Background About 1 million people worldwide commit suicide each year, and college students with suicidal ideation are at high risk of suicide. The prevalence of suicidal ideation in college students has been estimated extensively, but quantitative syntheses of overall prevalence are scarce, especially in China. Accurate estimates of prevalence are important for making public policy. In this paper, we aimed to determine the prevalence of suicidal ideation in Chinese college students. Objective and Methods Databases including PubMed, Web of Knowledge, Chinese Web of Knowledge, Wangfang (Chinese database) and Weipu (Chinese database) were systematically reviewed to identify articles published between 2004 to July 2013, in either English or Chinese, reporting prevalence estimates of suicidal ideation among Chinese college students. The strategy also included a secondary search of reference lists of records retrieved from databases. Then the prevalence estimates were summarized using a random effects model. The effects of moderator variables on the prevalence estimates were assessed using a meta-regression model. Results A total of 41 studies involving 160339 college students were identified, and the prevalence ranged from 1.24% to 26.00%. The overall pooled prevalence of suicidal ideation among Chinese college students was 10.72% (95%CI: 8.41% to 13.28%). We noted substantial heterogeneity in prevalence estimates. Subgroup analyses showed that prevalence of suicidal ideation in females is higher than in males. Conclusions The prevalence of suicidal ideation in Chinese college students is relatively high, although the suicide rate is lower compared with the entire society, suggesting the need for local surveys to inform the development of health services for college students.

To determine the prevalence of exclusive breast feeding in working women and to identify the factors effecting exclusive breast feeding in working women. This cross-sectional survey was conducted in Faisalabad city within a period of six months from June 2016 to December 2016. Working women of age 18 to 45 years, working as doctors, teachers, nurses and bankers in public (government) setup were included. The data was collected using interview method by pre-structured questionnaire. Multi-variable logistic regression model was developed considering EBF practice as dependent and the significant independent variables. Results were reported as Crude Odds Ratio (COR) or Adjusted Odds Ratio (AOR) with 95% Confidence Intervals (CIs). Prevalence of exclusive breast feeding (EBF) was 166 (41.5%). EFB practice was significantly less in doctors and bankers as compared to nurses and teachers (p-value <0.001). Women working as nurses and teachers, having one or two children and short working hours had higher prevalence of exclusive breast feeding. Women having prior knowledge about EBF, training of EBF and women who had previously heard about EBF had five time higher rate of breast feeding. Women having knowledge of colostrum had three times higher EBF practice [odds ratio: 3.02 (1.86-4.91)]. Women having knowledge about hazards of bottle feeding had 12.7 times higher prevalence of EBF [odds ratio: 12.72 (5.70-28.38)]. Those who knew about expression of breast milk had three times higher prevalence of EBF [odds ratio: 3.0 (1.98-4.55)]. Mothers working in organizations that support EBF had 4.1 times higher prevalence of EBF [odds ratio: 4.1 (2.67-6.21)]. And proper training of mothers about correct expression technique of breast milk had 12 time [odds ratio: 12.06 (4.97-29.23)] higher prevalence of EBF. Long working hours, banking profession, family income and lack of proper knowledge about exclusive breast feeding are responsible for non-EBF practice in working women. Proper Knowledge and awareness about exclusive breastfeeding and provision of facilities for exclusive breastfeeding (EBF) by the organizations can play a significant role in promoting it.

We studied to what extent the level of scientific knowledge on exceptionally rare metabolic inherited diseases and their potential orphan medicinal products is associated with sponsors deciding to apply for an orphan designation at the US Food and Drug Administration (FDA) or the European Medicines Agency (EMA). All metabolic diseases with a genetic cause and prevalence of less than 10 patients per 1 million of the population were selected from the 'Orphanet database of Rare diseases'. The outcome of interest was the application for an orphan designation at FDA or EMA. The level of publicly available knowledge of the disease and drug candidate before an orphan designation application was defined as whether the physiological function corresponding with the pathologic gene and initiation of the pathophysiological pathway was known, whether an appropriate animal study was identified for the disease, whether preclinical proof of concept was ascertained and the availability of data in humans. Other determinants included in the study were metabolic disease class, the prevalence of the disease, prognosis and time of first description of the disease in the literature. Univariate relative risks (RRs) and 95% confidence intervals (CIs) of an orphan designation application were calculated for each of these determinants. In addition, a multivariate Cox regression analysis was conducted (Forward LR). In total, 166 rare metabolic genetic diseases were identified and included in the analysis. For only 42 (25%) of the diseases an orphan designation application was submitted at either FDA or EMA before January 2012. The multivariate analysis identified preclinical proof of concept of a potential medicinal product as major knowledge related determinant associated with an orphan designation application (RRadj 3.9, 95% CI 1.9-8.3) and confirmed that prevalence of the disease is also associated with filing an application for an orphan designation (RRadj 2.8, 95% CI 1.4-5.4). For only one out of four known exceptionally rare metabolic inherited diseases sponsors applied for an orphan designation at FDA or EMA. These applications were found to be associated with the prevalence of the rare disease and the level of available scientific knowledge on the proof of concept linking possible drug candidates to the disease of interest.

Objectives To determine the prevalence and health outcomes of meticillin-resistant Staphylococcus aureus (MRSA) colonisation in elderly care home residents. To measure the effectiveness of improving infection prevention knowledge and practice on MRSA prevalence. Setting Care homes for elderly residents in Leeds, UK. Participants Residents able to give informed consent. Design A controlled intervention study, using a stepped wedge design, comprising 65 homes divided into three groups. Baseline MRSA prevalence was determined by screening the nares of residents (n=2492). An intervention based upon staff education and training on hand hygiene was delivered at three different times according to group number. Scores for three assessment methods, an audit of hand hygiene facilities, staff hand hygiene observations and an educational questionnaire, were collected before and after the intervention. After each group of homes received the intervention, all participants were screened for MRSA nasal colonisation. In total, four surveys took place between November 2006 and February 2009. Results MRSA prevalence was 20%, 19%, 22% and 21% in each survey, respectively. There was a significant improvement in scores for all three assessment methods post-intervention (p≤0.001). The intervention was associated with a small but significant increase in MRSA prevalence (p=0.023). MRSA colonisation was associated with previous and subsequent MRSA infection but was not significantly associated with subsequent hospitalisation or mortality. Conclusions The intervention did not result in a decrease in the prevalence of MRSA colonisation in care home residents. Additional measures will be required to reduce endemic MRSA colonisation in care homes. PMID:22240647

To determine laypeople's knowledge and awareness of stuttering in Japan. A total of 303 respondents, recruited by street sampling, completed a questionnaire assessing the prevalence, onset, gender distribution, occurrence in different races, cause, treatment, association with intelligence, and hereditariness of stuttering. The questionnaire used was a Japanese version of that devised by Van Borsel, Verniers, and Bouvry (1999) for use in Belgium. Although around half of the respondents had heard or met a stutterer, they tended to misunderstand the stuttering; e.g., respondents estimated the prevalence of stuttering as high. Knowledge also differed according to age, gender, and education level. Specifically, older individuals, females, and individuals with higher levels of education tended to have greater knowledge of stuttering. In comparing the results of the present study with similar studies conducted in Belgium, China, and Brazil, we observed several similarities and differences. Although most respondents were to some extent familiar with stuttering, their overall knowledge of the condition was limited. Certain factors could be involved in having knowledge of stuttering, such as one's life experience, cultural background, and social attitudes toward stuttering. The findings suggest the need for growing knowledge and awareness of stuttering. Copyright © 2018 Elsevier Inc. All rights reserved.

To investigate the prevalence and determinants of student and parental attitudes toward the education of children affected by HIV/AIDS in areas of rural China where AIDS is prevalent. A cross-sectional study of a random sample of students (n=732) and their parents (n=732) conducted in April 2010, using a questionnaire and in-depth interview. Twenty-six per cent of students and 29% of parents had a 'good' attitude toward the education of children affected by HIV/AIDS. Following adjustment for sociodemographic characteristics, students' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (adjusted odds ratio [aOR]= 3.13) and their parents' attitudes (aOR= 2.38), but not with knowledge of HIV/AIDS transmission, prevention or their parents' knowledge. Parents' attitudes were significantly associated with knowledge of HIV/AIDS non-transmission (aOR= 2.12) and their children's attitudes (aOR= 2.52), but not with knowledge of HIV/AIDS transmission, prevention or their children's knowledge. Stigma and discrimination undermine the right to education of HIV/AIDS-affected children in rural China. Improving non-transmission knowledge may improve caring attitudes. HIV/AIDS public health educational campaigns highlighting non-transmission and extending family education, combined with school education, may help to enhance an environment of non-discrimination and safeguard public support programs for the right to education of children affected by HIV/AIDS. © 2013 The Authors.

Soil-transmitted helminths (STH) and Schistosoma mansoni infections are the major neglected tropical diseases that result in serious consequences on health, education and nutrition in children in developing countries. The Ethiopian Orthodox church students, who are called Yekolotemari in Amharic, live in areas with poor sanitation and hygiene. Moreover, they are not included in the national STH control programs. Thus, STH and S. mansoni infections prevalence is unknown. A cross-sectional study was conducted on 384 students in June 2014 to determine STH and S. mansoni infections prevalence. Moreover, the knowledge of students about STH and S. mansoni was assessed. Data on knowledge and clinical symptoms were collected using structured questionnaires via face to face interview. Stool specimens were examined by formol-ether concentration method. The overall prevalence of intestinal helminths infections was 85.9% (95% confidence interval (CI): 82.1-89%). STHs infections prevalence was 65.6% (95% CI: 60.7-70.2%). The prevalence of hookworm, Ascaris lumbricoides and Trichuris trichiura were 31.8% (95% CI: 27.3-36.6%), 29.4% (25-31%) and 3.1% (1.8-5.4%), respectively. On the other hand, S. mansoni prevalence was 14.3% (95% CI: 11.1-18.1%). Majority of students infected with S. mansoni had bloody stool with crud odds-ratio of 2.9 (95% CI: 1.5-5.5). Knowledge assessment showed that 50 (13%) and 18 (4.9%) of the respondents knew about transmission of STH and S. mansoni, respectively. The prevalence of STH and S. mansoni infections were high thus de-worming program should include the students of Ethiopian Orthodox churches. Furthermore, provision and use of sanitary facilities, health education for students to create awareness of parasitic infections and improved personal hygiene should be in place.

A cross-sectional study was conducted among 308 lactating camels selected from 15 herds from three different camel milk clusters in Isiolo County, Kenya, to determine prevalence of bovine and avian tuberculosis using Single Comparative Intradermal Tuberculin Skin test. Seventy-five (75) questionnaires were administered to pastoralists/herders, and focus group discussions were conducted among 3-5 pastoralists/herders selected from each camel herd to collect information on camel husbandry and health management practices and knowledge on tuberculosis in livestock and wildlife. An overall prevalence of bovine and avian reactors was 3.57 and 18.18%, respectively, with bovine and avian reactors for different clusters being 2.38, 3.82, and 4.48% and 25, 17.2, and 11.94%, respectively. There was significant difference (p < 0.05) in prevalence of bovine and avian reactors between different clusters. There was a negative correction (r = -0.1399) between herd size and bovine reactors, while there was a positive correlation (r = 0.0445) between herd size and avian reactors. The respondents indicated that camel herds are exposed to several risk factors like close contact with other herds or livestock or wildlife during grazing and at watering points. Pastoralists have poor knowledge on mode of infection and transmission of bovine or avian tuberculosis. The high prevalence of bovine and avian reactors and pastoralists' poor knowledge on mode of transmission signify potential risk to public health.

The aims of this study are (a) To determine the effect of training on the multiple-target lesion search performance; and (b) To examine the effect of target prevalence on the performance of radiologists and novices. We conducted four sessions of 500 trials in a lesion search on a medical image task in which participants searched for three different target lesions. Participants were 10 radiologists and novices. In each session, the prevalence of the different target lesions varied from low (2%) to high (40%). The sensitivity of novices was higher in the later sessions than in the first session, whereas there were no differences among sessions in radiologists. The improvement on sensitivity of novices was largely due to attenuations of false alarm (FA) errors. In addition, miss rates of the three targets did not differ in data of novices, whereas radiologists produced a higher miss rate for the highest prevalence target lesion (non-serious lesion) than for the other two lesions (serious lesions). The conclusions are (a) The training for the multiple-target lesion search task can be effective to reduce FA errors; and (b) The prevalence effect on lesion search can be attenuated by the multiple-target identification and the knowledge about seriousness of lesions. This suggests that acquired knowledge about normal cases and serious lesions is an important aspect of a radiologists’ skill in searching for medical lesions and their high performance levels.

In Kenya, RTIs had the second highest increase in disability-adjusted life years between 1990 and 2010, compared to other conditions. This study aims to determine the prevalence, knowledge, attitudes and practices for speeding in Thika and Naivasha districts in Kenya. Direct observations of vehicle speed were conducted at various times during the day and different days of the week on six roads selected based on a multi-stage sampling method in two districts to determine the prevalence of speeding. Roadside KAP interviews were administered to drivers, at motorcycle bays, petrol stations, and rest areas. Eight rounds of speed observations and four rounds of KAP interviews were conducted between July 2010 and November 2012. Results from the speeding observational studies show an overall high proportion of vehicles speeding above posted limits in both districts, with an average of 46.8% in Thika and 40.2% in Naivasha. Trend analysis revealed a greater decline in this prevalence in Thika (OR: 0.804, 95% CI: 0.793-0.814) than in Naivasha (OR: 0.932, 95% CI: 0.919-0.945) over the study period. On average, 58.8% of speeding vehicles in Thika and 57.2% of speeding vehicles in Naivasha travelled at 10 km/h or higher above speed limit. While the majority of respondents agreed that speeding is a cause of road traffic crashes in both Thika (70.3%) and Naivasha (68.7%), knowledge of speed limits at the location of the interview was limited. Enforcement levels also remained low, but subsequent rounds of data collection showed improvement, especially in Thika. This study demonstrates an improvement in the prevalence of speeding in two districts of Kenya over 2010-2012. It also highlights the need for further action to be taken to address the problem, and represents new data on speeding in Kenya and Africa. Copyright © 2013 Elsevier Ltd. All rights reserved.

Hepatitis B and HIV infections are endemic in sub-Saharan Africa including Ghana. Understanding the extent of the co-infection is critical to the optimal care of persons living with HIV and AIDS (PLHIV). We determined the prevalence and risk factors of HBV co-infection in PLHIV and assessed the knowledge of health care workers (HCW) in Antiretroviral Therapy (ART) clinics regarding the co-infection. A cross sectional study was conducted in five ART clinics to obtain data from a systematic random sample of PLHIV in the Eastern region of Ghana from March to June 2012. We used self-administered questionnaires to assess knowledge of HCW on knowledge and management of the co-infection. Descriptive statistics and logistic regression models were used for analysis at 5% significance level. Of 320 PLHIV recruited into study, with median age of 40 years (IQR: 33-50 years), 28 tested positive for HBsAg giving an overall prevalence of 8.8%. There were significant associations between HBV infection and being an adult (p=0.004), increasing serum ALT levels (p=0.002) and partner with history of HBV infection (p=0.010). HCW obtained 84.2% (SD± 20.53; 95% CI: 89-98.1) and 53.1% (SD± 35.06; 95% CI: 13.0-88.9) in the "general knowledge" and "management practice" indexes respectively. Prevalence of HBV-HIV co-infection was relatively high among PLHIV in Eastern region. Knowledge of HCW on management practices of HBV-HIV co-infection and HBV vaccination coverage among PLHIV were found to be relatively low. Regular trainings of HCW and a HBV vaccination programme targeted at PLHIV should be considered.

The Health-promotion through Obesity Prevention across Europe (HOPE) project aims to bring the European scientific knowledge on overweight, obesity and their determinants together and use the expertise of researchers across Europe to contribute to tackling the obesity epidemic. This special issue of Public Health Nutrition presents important results from one of the work packages of the HOPE project that aims at gaining and integrating knowledge on the determinants of nutrition, physical activity and obesity among schoolchildren and adolescents (aged 10-18 years) in different European regions. It includes contributions from Northern Europe (Norway), Central and Eastern Europe (Germany, Poland and the Czech Republic), Southern Europe (Greece) and Western Europe (Belgium and The Netherlands), as well as an overview of the availability of good-quality data on prevalence rates and trends in overweight (including obesity) among adolescents in European Union (EU) countries. The studies that are included report prevalence differences, data on relevant nutrition and physical activity behaviours, as well as potential physical and environmental behavioural determinants. These papers provide further evidence on differences in obesity and overweight prevalence among different EU regions and countries, and contribute to the further exploration of risk factors that may or should be addressed in obesity prevention efforts for school-aged children and adolescents in EU countries.

AIM: To investigate physicians’ knowledge including chronic hepatitis B (CHB) diagnosis, screening, and management in various stages of their training. METHODS: A voluntary 20-question survey was administered in Santa Clara County, CA where Asian and Pacific Islanders (API) account for a third of the population. Among the 219 physician participants, there were 63 interns, 60 second-year residents, 26 chief residents and 70 attending physicians. The survey asked questions regarding respondents’ demographics, general hepatitis B virus knowledge questions (i.e., transmission, prevalence, diagnostic testing, prevention, and treatment options), as well as, self-reported practice behavior and confidence in knowledge. RESULTS: Knowledge about screening and managing patients with CHB was poor: only 24% identified the correct tests to screen for CHB, 13% knew the next steps for patients testing positive for CHB, 18% knew the high prevalence rate among API, and 31% knew how to screen for liver cancer. Wald chi-square analysis determined the effect of training level on knowledge; in all cases except for knowledge of liver cancer screening (P = 0.0032), knowledge did not significantly increase with length in residency training or completion of residency. CONCLUSION: Even in a high-risk region, both medical school and residency training have not adequately prepared physicians in the screening and management of CHB. PMID:26078568

The aim of this study was to determine the prevalence of usage and the knowledge and attitudes towards dietary supplements among medical sciences and nonmedical sciences students from Croatia. The study was conducted based on a questionnaire about dietary supplement usage, knowledge and attitudes. The prevalence of dietary supplement use, among 910 university students was 30.5%. The most-used dietary supplements were vitamins (18.0% in medical sciences students and 9.8% in non-medical sciences students). For all students, the internet (66.1%) was the most common source of information, followed by healthcare professionals (33.2%). The most common reason for taking dietary supplements was to maintain good health (26.4%). Use of the internet rather than health professionals as a trusted information source should be revised among this young population. Supplement intake was significantly associated with body mass index (BMI) ( p = 0.016) and physical activity ( p = 0.050). Students with normal BMI (61.5%) and the most physically active students (37.7%) took significantly more dietary supplements. Results of this study could help medicine faculties to improve their curriculum and support the development of public health messages aimed at wise and safe use of dietary supplements.

Introduction Human African Trypanosomiasis (HAT) is a vector borne parasitic disease transmitted to humans by infected tse-tse flies cause morbidity including delayed child mental development. Reports of nuisance and bites from tse-tse flies by residents of Kachia grazing led to the study to determine the knowledge, practices and prevalence of HAT among residents of the grazing reserve. Methods We conducted active case search in a cross-sectional study using multi-stage sampling with probability proportionate to size. We administered structured questionnaire on Knowledge, practices relating to HAT prevention and screened for HAT using card agglutination test for Trypanosomiasis (CATT). Knowledge of HAT was scored 0-5 and categorized good (3-5) and poor (0-2) based on score, predisposition to risk of HAT as exposure to ≥two risk factors and, a case of HAT as any respondent that tested positive on CATT. We analysed data using Epi-info and MS-excel. Results Of the 300 respondents, mean age 39(±17years) interviewed, 56.3% were males, 12.0% had good knowledge of HAT and 76.3% were exposed to HAT risk factors. Prevention practices included clearing of overgrown bushes around houses (99%), use of insecticidal treated nets (75.7%) and protective clothing (41.0%). Males {Odds Ratio [OR] 5.0; 95% Confidence Interval (CI) 1.8 - 13.6}, age above 40 years {OR 5.0; 95% CI 1.1 - 24.4} and family history of HAT {OR 8.7; 95% CI 2.4 - 32.1} were significantly associated with HAT knowledge. None tested positive on CATT. Conclusion Despite poor knowledge of HAT, residents practiced HAT preventive measures and zero HAT prevalence was recorded. PMID:27222686

A random sample of 176 patients seen at least once during 1997 in a University hospital outpatient clinic serving rheumatology and geriatric patients were surveyed in a telephone interview to determine the prevalence of, and reasons for taking, alternative medications. Interviews were conducted from November 1997-March 1998. The survey elicited information about patients' ability to provide self-care, demographics, work status, satisfaction with current disease management, types of alternative medications taken, sources of information about the products, where they obtained the products, and reasons for taking the products. Patients also were questioned as to their knowledge of safety of these products. Statistical comparisons were determined between patients who used alternative agents and those who did not. Prevalence of use was 66%. Most patients thought that the agents were safe and took them because they believed they have "added benefits."

The gestation period is the period that determines the quality of human resources in the future because the development of the child is determined from the time of the fetus in utero. The most common nutrition problems suffered by pregnant women in Indonesia is Chronic Energy Deficiency (CED) and anemia. The aim of this research to determine the prevalence of anemia in pregnant women and the risk factors associated with anemia in urban and rural areas of North Sumatera Province. This research is as descriptive analyticwith cross-sectional approach. Total sample 140 pregnant women from the Medan City, Langkat District and South Labuhan Batu District, and was from June to October 2016. Data collected by using interviews, hemoglobinometer tool and analyzed with Chi-square test. Anemia was in 40.7% of pregnant women, and the incidence of anemia is more common in pregnant women in urban areas than in rural areas. The factors associated with anemia in pregnant women is parity, knowledge of nutrition, diet and the risk of chronic energy deficiency (p <0.05). This study concludes that the prevalence of anemia in pregnant women in North Sumatra was higher than the national prevalence.

Background Soil-transmitted helminths (STH) and Schistosoma mansoni infections are the major neglected tropical diseases that result in serious consequences on health, education and nutrition in children in developing countries. The Ethiopian Orthodox church students, who are called Yekolotemari in Amharic, live in areas with poor sanitation and hygiene. Moreover, they are not included in the national STH control programs. Thus, STH and S. mansoni infections prevalence is unknown. Methods A cross-sectional study was conducted on 384 students in June 2014 to determine STH and S. mansoni infections prevalence. Moreover, the knowledge of students about STH and S. mansoni was assessed. Data on knowledge and clinical symptoms were collected using structured questionnaires via face to face interview. Stool specimens were examined by formol-ether concentration method. Results The overall prevalence of intestinal helminths infections was 85.9% (95% confidence interval (CI): 82.1–89%). STHs infections prevalence was 65.6% (95% CI: 60.7–70.2%). The prevalence of hookworm, Ascaris lumbricoides and Trichuris trichiura were 31.8% (95% CI: 27.3–36.6%), 29.4% (25–31%) and 3.1% (1.8–5.4%), respectively. On the other hand, S. mansoni prevalence was 14.3% (95% CI: 11.1–18.1%). Majority of students infected with S. mansoni had bloody stool with crud odds-ratio of 2.9 (95% CI: 1.5–5.5). Knowledge assessment showed that 50 (13%) and 18 (4.9%) of the respondents knew about transmission of STH and S. mansoni, respectively. Conclusions The prevalence of STH and S. mansoni infections were high thus de-worming program should include the students of Ethiopian Orthodox churches. Furthermore, provision and use of sanitary facilities, health education for students to create awareness of parasitic infections and improved personal hygiene should be in place. PMID:27203749

To measure the perceived risk of acquired immunodeficiency syndrome (AIDS) among international travellers, to measure their knowledge of the transmission and prevention of HIV infection abroad and to identify some of the determinants of this knowledge. Survey. Travellers' immunization clinic providing mostly primary preventive care to international travellers. All clients aged 18 to 50 years seen at the clinic between Oct. 2 and Dec. 21, 1989, before their departure. Sixteen statements measured knowledge of transmission and prevention of HIV infection. Standardized scales measured health beliefs. The response rate was 81% (331/409). Compared with other diseases AIDS was perceived to be associated with a low risk except by those travelling to countries with a high prevalence of AIDS. Most of the clients were found to have a good knowledge of HIV transmission to travellers, although some myths remained popular and some real routes of transmission, especially blood, remained underrated. In all, 70% of the subjects believed in the efficacy of condoms when used with local people, as compared with 79% when used with other tourists; this difference was greatest among travellers who perceived AIDS as being particularly severe but difficult to prevent. The determinants of the knowledge of HIV transmission and prevention were a high level of education, a mother tongue other than French, unmarried status, a high prevalence of AIDS at the destination, the duration of the trip and a high perceived risk of HIV infection. Counselling should teach travellers (a) not to underestimate their risk of HIV infection during their trip, (b) to decrease the risk of requiring health care in developing countries and (c) to rely on their own prudent sexual behaviour rather than on their assessment of the level of risk posed by the environment.

The global health professional survey is a project organized by the World Health Organization, to determine the smoking habits, knowledge and attitude towards tobacco control of health professionals in several countries around the world. This paper presents data from Kuwait and Bahrain. The survey period was between May 2000 and March 2001. A questionnaire was distributed to all physicians in Bahrain and to a random sample from Kuwait. The responses to knowledge and attitude questions were on a scale of 1-5, (1 strongly agree, 2 agree, 3 unsure, 4 disagree and 5 strongly disagree). Four hundred and seventy physicians from Bahrain and 1095 from Kuwait completed the questionnaire. The prevalence of cigarette smoking in Kuwait was: current smokers 18.4%, previous smokers 15.8%, Bahrain 14.6% and 14.3%. The prevalence of shisha smoking was 12% and 6.4% for Kuwait and Bahrain, (p=0.004). The mean scores of agreement with the association between passive smoking and lung diseases, lower respiratory tract infections in children were 1.6, 1.7 and 1.8, 1.9 for non smoking physicians and smoking physicians (P<0.01). The mean scores of agreement with the following policies: large health warning on cigarette packages, complete ban on tobacco advertisement and an increase in the price of cigarette were 1.3, 1.4, 1.7 and 1.7, 1.7, 2.5 for smoking and non-smoking physicians (p<0.01). Smoking physicians have less knowledge and less favorable attitude towards tobacco control compared to non-smokers. There was no difference in the prevalence of cigarette smoking between Kuwait and Bahrain, but the prevalence of shisha smoking was higher in Kuwait.

Painful sunburns at any age are one of the main risk factors for skin cancer. To determine the prevalence and predictors of sunburn among beachgoers. A cross-sectional health survey was conducted at the beach during the summer. Adults >18 years with an understanding of Spanish were interviewed using a questionnaire about behaviours, attitudes and knowledge related to sun exposure at the beach. A descriptive analysis was performed, and a log-binomial regression model was used to determine predictors of sunburn. The survey was completed by 1054 beachgoers, with a mean age of 43.8 (SD: 18.7) years, 61.2% women, skin phototypes i (13.6%), ii (22.3%), iii (34.0%) and iv (30.2%). 46.9% of responders reported at least one painful sunburn during the previous summer. Age, sex, education, skin phototype, midday sun exposure, sun protection habits, attitudes towards tanning and knowledge about skin cancer were identified as independent predictors of sunburn. It is necessary to develop photoprotection campaigns aimed at beachgoers, particularly in young people, men, those with skin phototypes I-III and secondary or university education. Educational strategies should be aimed at discouraging sun exposure at midday, changing attitudes towards tanning and improving knowledge about skin cancer. © 2017 John Wiley & Sons A/S.

Aim: Present study aimed to systematically review and quantitatively synthesize published data about the prevalence of Hepatitis B Virus (HBV) infection among high risk groups in Iran. Background: Determining true burden of Hepatitis B Virus (HBV) infection among high-risk groups relies on knowledge of occurrence measures such as prevalence rate. There is no conclusive and comprehensive data regarding to prevalence of HBV infection among high risk groups in Iran. Methods: Relevant studies were searched in PubMed, Scopus, Web of Knowledge and local databases. In addition, reference lists of relevant studies were searched manually. Two independent authors reviewed the eligibility of retrieved studies and extracted the required data. Studies reporting HBV infection among high risk groups were included in the meta-analysis using random effects models. Meta regression and sub-group analysis were considered as additional analyses. Results: The initial search yielded 566 citations. After the primary screen, 37 studies were selected for review. Meta-analysis results showed that pooled prevalence of HBV infection among high risk groups in Iran was 4.8% (95% confidence interval: 3.6%-6.1%), with the highest prevalence among in prisoners (5%; 3%-6%), and in central regions of Iran (7%; 4%-11%). Year of study may affect the observed heterogeneity in the estimated prevalence of HBV infection among injection drug users (IDUs) and prisoners. Conclusion: Our results indicate that prevalence of HBV infection among high risk groups was seemingly high in Iran. Health policy decision makers should be aware of prevalence of HBV infection among different high risk groups and in different regions of Iran.

Food allergy: epidemiology and natural history.

The prevalence of food allergy is rising for unclear reasons, with prevalence estimates in the developed world approaching 10%. Knowledge regarding the natural course of food allergies is important because it can aid the clinician in diagnosing food allergies and in determining when to consider evaluation for food allergy resolution. Many food allergies with onset in early childhood are outgrown later in childhood, although a minority of food allergy persists into adolescence and even adulthood. More research is needed to improve food allergy diagnosis, treatment, and prevention. Copyright © 2015 Elsevier Inc. All rights reserved.

Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 - 0.83, P = 0.004), unemployment (0.67; 0.49 - 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 - 0.92, P < 0.012). Whilst, older age (1.73; 1.30 - 2.29, P < 0.001) and residing in Lira (2.02; 1.50 - 2.72, P < 0.001) were independent determinants of higher knowledge of TB. This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

People living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions, and misunderstandings that have persisted for many years. In the last decade, there has been an increase in individual literacy rate and increased access to technology in rural population. However, it is unclear if this has any effect on knowledge, attitude, and practice (KAP) attitude toward epilepsy. Our primary aim is to evaluate KAP toward epilepsy. In addition, we also estimated the prevalence of stroke and epilepsy in rural South India. Using a 14-item questionnaire, we assessed KAP toward epilepsy and identified determinants of inappropriate attitudes toward people with epilepsy and 10-item questionnaires to assess the prevalence of epilepsy and stroke among 500 randomly selected populations in a Pattaravakkam village (Tamil Nadu, India). About 87.7% of the people had heard or read about epilepsy. Negative attitudes appeared to be reinforced by beliefs that epilepsy is hereditary (23.1%), kind of insanity (22.6%), or as contagious (12.0%). The knowledge about the clinical characteristics and first aid to a person during a seizure was 25.8%. About 36.5% of people think that society discriminates people with epilepsy. Moreover, our prevalence study showed that 8.7% people are suffering from epilepsy and 3.7% had stroke previously and at the day of survey, the stroke prevalence is 3.3%. Even with increased literacy, technology, and communication devices, the KAP of people toward epilepsy is relatively low. General public education campaigns and specific school education campaigns children should be encouraged to increase the KAP toward epilepsy. The prevalence and pattern of epilepsy and stroke is on the higher side in the village of Pattaravakkam. Future research regarding the value of targeted education in improving KAP will be worthwhile.

To determine the prevalence of major risk factors including dietary modification, Body Mass Index (BMI), Blood Pressure (BP) and physical activity in medical students of government teaching hospitals of Karachi. A cross sectional study was conducted on students of Dow Medical College, Karachi, Pakistan through a structured pre-tested questionnaire. Non-probability purposive sampling was used. Smoking, hypertension, family history of cardiovascular disease (CVD), overweight and low physical activity levels are risk factors the presence of which can lead to development of CVD. Prevalence of these risk factors was determined by asking appropriate questions and through measurement of BMI and blood pressure for overweight and hypertension respectively. Awareness of risk factors was determined through knowledge of the effect of various food substances on development of CVD and of adoption of dietary changes keeping in mind the risk of developing CVD. SPSS 16.0 was used for statistical analysis. A total of 132 medical students were included in the study of which 57 (43.2%) and 75 (56.8%) were male and female respectively with mean age of 20.85 +/- 1.21 years. About 15.9% of students had elevated blood pressure i.e. > or = 140/90 mmHg. Twenty eight percent of the total students were found to be underweight and 17.4% were overweight, 5% had some history of CVD, 56.8% had family history of CVD, 9.4% were smokers and 29.5% had high physical activity level. About 87.1% had modified their diet for preventing CVD. Most of the students had adequate knowledge about the cardiovascular risk factors Majority of students were not overweight. A high prevalence of cardiovascular risk factors; family history and elevated blood pressure was present. Awareness in terms of knowledge was satisfactory but implementation in terms of diet modification and adequate physical activity was lacking.

Introduction The burden of non-communicable diseases (NCDs) is growing in sub-Saharan Africa combined with an already high prevalence of infectious disease, like HIV. Engaging the formal employment sector may present a viable strategy for addressing both HIV and NCDs in people of working age. This study assesses the presence of three of the most significant threats to health in Namibia among employees in the formal sector: elevated blood pressure, elevated blood glucose, and HIV and assesses the knowledge and self-perceived risk of employees for these conditions. Methods A health and wellness screening survey of employees working in 13 industries in the formal sector of Namibia was conducted including 11,192 participants in the Bophelo! Project in Namibia, from January 2009 to October 2010. The survey combined a medical screening for HIV, blood glucose and blood pressure with an employee-completed survey on knowledge and risk behaviors for those conditions. We estimated the prevalence of the three conditions and compared to self-reported employee knowledge and risk behaviors and possible determinants. Results 25.8% of participants had elevated blood pressure, 8.3% of participants had an elevated random blood glucose measurement, and 8.9% of participants tested positive for HIV. Most participants were not smokers (80%), reported not drinking alcohol regularly (81.2%), and had regular condom use (66%). Most participants could not correctly identify risk factors for hypertension (57.2%), diabetes (57.3%), or high-risk behaviors for HIV infection (59.5%). In multivariate analysis, having insurance (OR:1.15, 95%CI: 1.03 – 1.28) and a managerial position (OR: 1.29, 95%CI: 1.13 – 1.47) were associated with better odds of knowledge of diabetes. Conclusion The prevalence of elevated blood pressure, elevated blood glucose, and HIV among employees of the Namibian formal sector is high, while risk awareness is low. Attention must be paid to improving the knowledge of health-related risk factors as well as providing care to those with chronic conditions in the formal sector through programs such as workplace wellness.

Summary Background In 2004, cases of HIV and syphilis were reported in an indigenous community in the Peruvian Amazon. This study sought to determine the prevalence of HIV and syphilis in four remote communities of the same indigenous ethnic group located further from an urban center than the original community, and to identify risk factors for HIV and syphilis transmission. Methods Rapid and confirmatory tests for HIV and syphilis were performed. A questionnaire elicited demographic information, risk factors for sexually transmitted infections, and knowledge/beliefs about HIV/AIDS. Results We collected 282 blood samples and conducted interviews with 281 (99.6%) participants. The confirmed syphilis prevalence rate was 3.2% (9/282; 3.7% (5/135) for men and 2.7% (4/147) for women). The confirmed HIV prevalence rate was 0.7% (2/282), with both infections in men who had sex with men (MSM). Self-reported MSM activity was 39.7%. There was poor knowledge about HIV infection, transmission, and prevention, and low acceptance of known prevention methods. Conclusions HIV and syphilis are now prevalent in remote Amazonian communities of an indigenous group in Peru. Expansion of the HIV epidemic into the Amazon requires an urgent public health response.

Determine the prevalence and characteristics of tobaccoism, as well as some attitudes and their knowledge about tobaccoism in nursing university students in Catalonia. A descriptive study with transversal section has been done. A self-filling anonymous questionnaire was designed following the guidelines of the European Regional Office of the W.H.O. We selected a sample of conglomerates of classrooms at random which was stratified according to levels in all the university schools in Catalonia. The field work was performed during the first term of the academic year 1994-1995 handing the questionnaires individually to the students and collecting them once filled. In the data analysis we used the ji squared test to Pearson with the Yates' correction and the lineal tendency test of Mantel-Haenszel. 904 students answered the questionnaire. The global prevalence of smokers is 38.7% (IC 95%: 35.8-41.6). There were no significant differences when considering levels or sex. The prevalence of tobaccoism in students over 24 years of age is 13% higher (p < 0.01) than in the group between 18 and 24 years of age. The group of daily smokers consumes an average of 12 cigarettes per day (DE: 5.9 cig/day). Significant differences were observed between smokers and nonsmokers in all the attitude variables analysed towards tobaccoism. 32% of third year students consider their knowledge is not enough in order to give advice against tobacco. A prevalence higher than 30% of the established objective in the Health Plan in Catalonia has been observed for the nursing professionals in the year 2000.

This study aimed to determine the relationship between child feeding practices, food habits, and anthropometric indicators with cognitive performance of preschoolers aged 4-6 years in Peninsular Malaysia (n=1933). Parents were interviewed on socio-demographic background, nutrition knowledge, child feeding practices and food habits. Height and weight of the preschoolers were measured; BMI-for-age, weight-for-age and height-for-age were determined. Cognitive performance was assessed using Raven's Colored Progressive Matrices. The mean monthly household income was RM3610 and 59.6% of parents attained secondary education. Thirty-three percent of parents had good knowledge on nutrition, 39% satisfactory and 28% poor. For child feeding practices, perceived responsibility had the highest mean score (M=3.99, SD=0.72), while perceived child weight had the lowest (M=2.94, SD=0.38). The prevalence of possible risk of overweight, being overweight, and obesity were 3.9%, 7.9% and 8.1%, respectively, whereas the prevalence of underweight and stunting were 8.0% and 8.4%, respectively. Breakfast was the second most frequently skipped meal (16.8%) after dinner (18.1%). The mean cognitive score was 103.5 (SD=14.4). Height-for-age and consumption of dinner were found to contribute significantly towards cognitive performance after controlling for socio-demographic background and parent's nutrition knowledge.

Knowledge about symptoms and transmission of tuberculosis determines health seeking behavior and helps in prevention of tuberculosis transmission in the community. Such data is useful for policy makers to formulate information, education and communication strategies for tuberculosis control. A secondary data analysis of India demographic and health survey, 2005/6 was carried out. Questions about self-reported tuberculosis, transmission and curability of tuberculosis were analysed. Correct knowledge (without misconceptions) about tuberculosis transmission was used as a dependant variable and the explanatory variables tested were: demographic data, education, wealth quintiles, frequency of exposure to media and the curability of tuberculosis. Determinants of correct knowledge without misconceptions were tested by univariate and multivariate analyses using national weighting factor to adjust for complex sampling design. A total of 109,070 households (response rate of 93.5%) and 198,718 participants (response rate of 91.6%) completed the survey. The samples of men and women interviewed were 74,360 and 124,358 respectively. Prevalence rate of self-reported tuberculosis was 445 per 100,000 usual household residents and 4.60 per 1,000 participants. The number of respondents who had "heard of an illness called tuberculosis" was 177,423 (89.3%). Of these 47,487 (26.8%) participants did not know and 55.5% knew about the correct mode of tuberculosis transmission i.e. "Through the air when coughing or sneezing". The common misconceptions about transmission were "Through food" (32.4%), "Sharing utensils" (18.2%), and "Touching a person with tuberculosis" (12.3%). Only 52,617 (29.7%) participants had correct knowledge without misconceptions. Being male (aOR 1.17, 95% CIs 1.14, 1.21), being a Hindu (aOR 1.20, 95% CIs 1.14, 1.26) or Muslim (aOR 1.26, 95% CIs 1.18, 1.34), listening to radio (aOR 1.08, 95% CIs 1.04, 1.13) and "Tuberculosis can be cured" (aOR 1.47, 95% CIs 1.41, 1.53) were associated with correct knowledge without misconceptions. Knowledge about tuberculosis transmission is very poor and misconceptions still exist. Among the traditional mass media, the frequency of listening to radio was associated with correct knowledge about tuberculosis transmission. Strategies to deliver information, education and communication campaigns could be improved.

The need for a basic epidemiological study, according to international standards, of the prevalence of IBD in Slovakia was increased by the dissolution of Czechoslovakia. This paper presents the results of CD prevalence to 30 April 1994 in Slovakia. To evaluate the statistical data of the prevalence of the disease according to age, sex, regions and districts, the authors employed the multi-dimensional Kruskal-Wallis test and cluster analysis and determined that the prevalence of CD in Slovakia is 6.75/100.000 inhabitants. The distribution differences indicate the need for further investigations of environmental differences. The socio-economic and psychological evaluation of the patients examined revealed some interesting associations. The psychological reaction to the disease is neurotic and depressive and a higher occurrence of affective symptomatology was observed in patients with permanent partnership and with children. On the other hand, the educational level and knowledge concerning the disease on the part of the patient had a positive influence on the reaction to the disease.

Arterial hypertension is among the most important risk factors of atherosclerosis and associated cardiovascular pathology with a prevalence rate estimated at 20-30% of the adult population. Nowadays, it is recommended to perform an individual assessment of cardiovascular risk in a patient and to determine the threshold value for arterial hypertension, even though blood pressure classification values according to the European Society of Hypertension and the European Society of Cardiology (ESH/ESC), as well as the Polish Society of Hypertension (PTNT) have remained unchanged. To determine what nurses with a Bachelor of Nursing degree know about the prevalence and classification of arterial blood pressure, as well as sequellae of arterial hypertension. This study was done in 116 qualified nurses (112 females, 4 males; age 21-50; seniority 0-29 years). The research period was from June 2007 to January 2008. The research tool was a questionnaire devised by the authors. We found that half (on the average) of those questioned have an up-to-date knowledge regarding classification of blood pressure and prevalence of arterial hypertension but just one out of three respondents (on the average) was able to describe its sequellae. Relatively less known among nurses with a Bachelor of Nursing degree were aspects of "white coat hypertension". Statistically significant differences regarding correct answers were noted depending on seniority (p = 0.002), place of work p < 0.001), or position (p < 0.001). There were no differences depending on age, place of residence, marital status, or form of postgraduate education of nurses with a Bachelor of Nursing degree. It is necessary to improve knowledge among students of nursing (BN degree) about current classification of blood pressure, as well as prevalence of arterial hypertension and its sequellae.

Early childhood is a period during which many factors influence the development of lifelong eating habits. This study aimed to assess the nutritional status of young children and to determine factors related to eating habits. A total of 992 children aged 5-6 years attending kindergartens that participated in the Bright Start Nutrition programme in the Klang Valley were included in the study. Anthropometric measurements were taken and body mass index (BMI) calculated. A questionnaire to assess the children's nutrition knowledge was administered through interviews, while their mothers self-administered another set of questionnaires regarding knowledge, attitude and practice on nutrition. The mean BMI was 15.7 +/- 2.7 kg/m2 in boys and 15.4 +/- 2.4 kg/m2 in girls. Based on the WHO 2007 growth reference, the prevalence of overweight and obesity were 9.1% and 9.3%, respectively; while the prevalence of thinness and stunting were 5.8% and 3.9%, respectively. Most of the children consumed breakfast (86.4%), lunch (94.1%) and dinner (93.4%) daily. The majority liked fruits (95.1%), snacks (93.8%), Western fast food (93.3%) and milk (90.8%), while less than two-thirds (65.1%) liked vegetables. The mean nutrition knowledge scores for the children and mothers were 73.2 +/- 9.8% and 60.2 +/- 18.8%, respectively. Maternal nutrition knowledge was correlated positively with children's vegetable intake (r=0.111, p<0.05) and negatively with snack intake (r = -0.134, p<0.05). These results showed a higher prevalence of overweight and obesity than underweight and thinness among the urban young children studied. As mother's nutrition knowledge was found to exert a positive influence on children's eating habits, it is important to provide nutrition education to both mothers and children when conducting intervention programmes.

Socio-demographic determinants and prevalence of Tuberculosis knowledge in three slum populations of Uganda

PubMed Central

2012-01-01

Background Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. Methods A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. Results We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 – 0.83, P = 0.004), unemployment (0.67; 0.49 – 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 – 0.92, P < 0.012). Whilst, older age (1.73; 1.30 – 2.29, P < 0.001) and residing in Lira (2.02; 1.50 – 2.72, P < 0.001) were independent determinants of higher knowledge of TB. Conclusion This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

OBJECTIVES: To measure the perceived risk of acquired immunodeficiency syndrome (AIDS) among international travellers, to measure their knowledge of the transmission and prevention of HIV infection abroad and to identify some of the determinants of this knowledge. DESIGN: Survey. SETTING: Travellers' immunization clinic providing mostly primary preventive care to international travellers. PARTICIPANTS: All clients aged 18 to 50 years seen at the clinic between Oct. 2 and Dec. 21, 1989, before their departure. MAIN OUTCOME MEASURES: Sixteen statements measured knowledge of transmission and prevention of HIV infection. Standardized scales measured health beliefs. RESULTS: The response rate was 81% (331/409). Compared with other diseases AIDS was perceived to be associated with a low risk except by those travelling to countries with a high prevalence of AIDS. Most of the clients were found to have a good knowledge of HIV transmission to travellers, although some myths remained popular and some real routes of transmission, especially blood, remained underrated. In all, 70% of the subjects believed in the efficacy of condoms when used with local people, as compared with 79% when used with other tourists; this difference was greatest among travellers who perceived AIDS as being particularly severe but difficult to prevent. The determinants of the knowledge of HIV transmission and prevention were a high level of education, a mother tongue other than French, unmarried status, a high prevalence of AIDS at the destination, the duration of the trip and a high perceived risk of HIV infection. CONCLUSIONS: Counselling should teach travellers (a) not to underestimate their risk of HIV infection during their trip, (b) to decrease the risk of requiring health care in developing countries and (c) to rely on their own prudent sexual behaviour rather than on their assessment of the level of risk posed by the environment.

Low back pain (LBP) and neck pain are part of the common work-related musculoskeletal disorders with a large impact on the affected person. Despite having a multifactorial aetiology, ergonomic factors play a major role thus necessitating workers' education. To determine the prevalence of ergonomic-related LBP and neck pain, and describe the effect of a knowledge-based ergonomic intervention amongst administrators in Aga Khan University Hospital, Nairobi. This study applied a mixed method design utilizing a survey and two focus group discussions (FGD). A self-administered questionnaire was distributed to 208 participants through systematic sampling. A one hour knowledge-based ergonomic session founded on the survey results was thereafter administered to interested participants, followed by two FGDs a month later with purposive selection of eight participants to explore their experience of the ergonomic intervention. Quantitative data was captured and analyzed using SPSS by means of descriptive and inferential statistics, whereas thematic content analysis was used for qualitative data. Most participants were knowledgeable about ergonomic-related LBP and neck pain with a twelve month prevalence of 75.5% and 67.8% respectively. Continual ergonomic education is necessary for adherence to health-related behaviours that will preventwork-related LBP and neck pain.

University students and HIV in Namibia: an HIV prevalence survey and a knowledge and attitude survey

PubMed Central

2012-01-01

Background With an overall adult HIV prevalence of 15.3%, Namibia is facing one of the largest HIV epidemics in Africa. Young people aged 20 to 34 years constitute one of the groups at highest risk of HIV infection in Namibia. However, little is known about the impact of HIV on this group and its access to healthcare. The purpose of this study was to estimate HIV prevalence, to assess the knowledge of and attitudes towards HIV/AIDS, and to assess access to healthcare among university students in Namibia. Methods We assessed HIV/AIDS knowledge and attitudes, HIV prevalence and access to healthcare among students at the Polytechnic of Namibia and the University of Namibia. HIV prevalence was tested through anonymous oral fluid-based tests. Results Half (n = 2790/5568) of the university students and 45% (n = 2807/6302) of the Polytechnic students participated in the knowledge and attitudes surveys. HIV/AIDS knowledge was reasonable, except for misperceptions about transmission. Awareness of one's own HIV status and risks was low. In all, 55% (n = 3055/5568) of university students and 58% (n = 3680/6302) of Polytechnic students participated in the HIV prevalence survey; 54 (1.8%) university students and 103 (2.8%) Polytechnic students tested HIV positive. Campus clinics were not the major providers of healthcare to the students. Conclusions Meaningful strategies addressing the gap between knowledge, attitude and young people's perception of risk of HIV acquisition should be implemented. HIV prevalence among Namibian university students appears relatively low. Voluntary counselling and testing should be stimulated. Efforts should be made to increase access to healthcare through the campus clinics. PMID:22353579

We used an exploratory sequential mixed methods approach to study the association between cultural continuity, self-determination, and diabetes prevalence in First Nations in Alberta, Canada. We conducted a qualitative description where we interviewed 10 Cree and Blackfoot leaders (members of Chief and Council) from across the province to understand cultural continuity, self-determination, and their relationship to health and diabetes, in the Alberta First Nations context. Based on the qualitative findings, we then conducted a cross-sectional analysis using provincial administrative data and publically available data for 31 First Nations communities to quantitatively examine any relationship between cultural continuity and diabetes prevalence. Cultural continuity, or "being who we are", is foundational to health in successful First Nations. Self-determination, or "being a self-sufficient Nation", stems from cultural continuity and is seriously compromised in today's Alberta Cree and Blackfoot Nations. Unfortunately, First Nations are in a continuous struggle with government policy. The intergenerational effects of colonization continue to impact the culture, which undermines the sense of self-determination, and contributes to diabetes and ill health. Crude diabetes prevalence varied dramatically among First Nations with values as low as 1.2% and as high as 18.3%. Those First Nations that appeared to have more cultural continuity (measured by traditional Indigenous language knowledge) had significantly lower diabetes prevalence after adjustment for socio-economic factors (p =0.007). First Nations that have been better able to preserve their culture may be relatively protected from diabetes.

Background Undergraduate nursing education standards include acquisition of knowledge of ethics principles and the prevalence of health-care ethical dilemmas mandates that nursing students study ethics. However, little research has been published to support best practices for teaching/learning ethics principles. Purpose This study sought to determine if participation in an ethics consultation simulation increased nursing students' knowledge of nursing ethics principles compared to students who were taught ethics principles in the traditional didactic format. Methods This quasi-experimental study utilized a pre-test/post-test design with randomized assignment of students at three universities into both control and experimental groups. Results Nursing students' knowledge of nursing ethics principles significantly improved from pre-test to post-test ( p = .002); however, there was no significant difference between the experimental and control groups knowledge scores ( p = .13). Conclusion Further research into use of simulation to teach ethics principles is indicated.

Sexually transmitted infections constitute economic burden for developing countries, exposure to causative agents is an occupational hazard for female sex workers. Targeted interventions for this population can reduce the incidence and prevalence of sexually transmitted infections including human immunodeficiency virus, but barriers exists which can hinder effective implementation of such programs. This descriptive cross sectional study sought to assess the prevalence, knowledge and treatment practices of sexually transmitted infections among brothel based female sex workers. Three hundred and twenty three consenting female sex workers were surveyed using pre tested, interviewer administered questionnaires. More than half of the respondents (54.2%) had poor knowledge of symptoms of sexually transmitted infections. Only 13.9% were aware that sexually transmitted infections could be asymptomatic. The self reported prevalence of symptomatic sexually transmitted infections was 36.5%. About half of those with sexually transmitted infectionss sought treatment in a hospital or health centre while 32.5% from a patent medicine vendor. Most respondents (53.8%) mentioned the perceived quality of care as the main reason for seeking treatment in their chosen place. More of the respondents with good knowledge of sexually transmitted infections reported symptoms compared to those with fair and poor knowledge. The knowledge of sexually transmitted infections among these female sex workers is poor and the prevalence is relatively high. Efforts to improve knowledge promote and encourage preventive as well as effective treatment practices must be made for this population.

Occupational hazards, exposure to blood and body fluids (BBF) accidents and safety precautions constitute an important public health issue. We assessed the prevalence and determinants of exposure to occupational hazards among nurses, and their knowledge of occupational safety precautions. In a cross-sectional study, we surveyed 332 nurses working in 4 hospitals, Nablus, West Bank, Palestine, by a questionnaire. Bivariate analysis tested the associations between ever exposure and the high likelihood of BBF exposure and the independent socio-demographic and occupational variables. Binary logistic regression analysis was used to assess the associations between the same two exposures and selected independent variables (those significant in the bivariate analysis). Prevalence of ever exposure to BBF was 51.7%, and was associated with working in private and charitable hospitals (OR 2.62, 2.68, respectively), having 4-6 family members (OR 0.52) and "nursing" being as one's top career choice at university (OR 0.48). The prevalence of high likelihood of BBF exposure was 62.2%, and was associated with working in charitable and private hospitals (OR 7.81, 2.43, respectively) and "nursing" being as one's top career choice (OR 0.57). Regarding knowledge, most respondents believed it is necessary to enact laws and regulations regarding occupational safety precautions, reported the use of sharps containers, immediate disinfection after an accident, reporting an accident, and using personal protective equipment. Nurses had adequate knowledge of the risks of their hospital work. Nevertheless, they exhibited high prevalence of exposure to BBF accidents. Future studies are needed to re-evaluate existing occupational safety guidelines in hospitals, establish monitoring and evaluation protocols for health care workers' adherence to the guidelines, and institute well-defined policies for reporting occupational injury incidents so these can be handled appropriately.

Introduction: People living with epilepsy continue to suffer from enacted or perceived stigma that is based on myths, misconceptions, and misunderstandings that have persisted for many years. In the last decade, there has been an increase in individual literacy rate and increased access to technology in rural population. However, it is unclear if this has any effect on knowledge, attitude, and practice (KAP) attitude toward epilepsy. Objective: Our primary aim is to evaluate KAP toward epilepsy. In addition, we also estimated the prevalence of stroke and epilepsy in rural South India. Materials and Methods: Using a 14-item questionnaire, we assessed KAP toward epilepsy and identified determinants of inappropriate attitudes toward people with epilepsy and 10-item questionnaires to assess the prevalence of epilepsy and stroke among 500 randomly selected populations in a Pattaravakkam village (Tamil Nadu, India). Results: About 87.7% of the people had heard or read about epilepsy. Negative attitudes appeared to be reinforced by beliefs that epilepsy is hereditary (23.1%), kind of insanity (22.6%), or as contagious (12.0%). The knowledge about the clinical characteristics and first aid to a person during a seizure was 25.8%. About 36.5% of people think that society discriminates people with epilepsy. Moreover, our prevalence study showed that 8.7% people are suffering from epilepsy and 3.7% had stroke previously and at the day of survey, the stroke prevalence is 3.3%. Conclusion: Even with increased literacy, technology, and communication devices, the KAP of people toward epilepsy is relatively low. General public education campaigns and specific school education campaigns children should be encouraged to increase the KAP toward epilepsy. The prevalence and pattern of epilepsy and stroke is on the higher side in the village of Pattaravakkam. Future research regarding the value of targeted education in improving KAP will be worthwhile.

The highest prevalence of HIV infection occurs in Sub-Saharan Africa and hepatitis B virus (HBV), and hepatitis C virus (HCV) prevalence are the second highest in Sub-Saharan Africa including Malawi. Health-care workers (HCWs) play an important role in the prevention of, response to, and management of these infectious diseases. There is, however, no published research about the level of knowledge and attitudes toward HIV, HBV, and HCV infection among Malawian HCWs. The purpose of this study was to explore and determine the knowledge of and attitudes toward HIV, HBV, and HCV among a targeted population of Malawian HCWs. A cross-sectional community-based participatory research with 194 HCWs was completed employing health survey method. The project was a collaborative effort between nursing faculties in the USA and Malawian. A one-way analysis of variance (ANOVA) with the Bonferroni adjustment for multiple comparisons was used to assess the differences in knowledge and attitude among three subgroups of HCWs. Of 194 of Malawian HCWs surveyed, 41% were support staff, 37% were nursing students, and 22% were health-care professionals. Both health-care professionals and support staff had high knowledge scores related to HIV/AIDS, and their attitudes were mainly positive. However, a series of one-way ANOVAs revealed significant differences in knowledge and attitude toward HIV/AIDs, HBV, and HCV among HCWs ( P < 0.01). The majority had less knowledge about HBV and HCV and more negative attitudes toward hepatitis. This study highlights the ongoing need for reducing negative attitudes toward HIV, HBV, and HCV; and providing health education among HCWs, especially focusing on HBV and HCV prevention. The findings of the research project can be used to develop interventions addressing low HBV- and HCV-related knowledge and attitudes.

In spite of intervention efforts, in Uganda, as in other developing countries, high levels of anaemia among pregnant women continue. Anaemia among women of reproductive age (15-49 years) is a matter of national concern. This study was carried out to assess determinants of anaemia in Kiboga district. This was a single cross-sectional, descriptive survey. The anaemia status of the pregnant women was determined by measuring their haemoglobin levels. Possible determinant factors including socio-economic characteristics, knowledge, attitudes, practices and food intake were assessed using a structured questionnaire. Results showed that the prevalence of anaemia among pregnant women in Kiboga district was high enough (63.1%) to be described as a severe public health problem. The uptake and utilisation of the public-health intervention package to combat anaemia in pregnancy was low, with iron/folic acid supplementation at 13.2%, use of intermittent preventive treatment of malaria 45.4%, and use of de-worming medicines 14.5%. Women from households without a functional radio were 2.07 times more likely be anaemic (95%CI, 1.08-3.00) compared with women from households where there was a functional radio. There was little awareness and functional knowledge about anaemia among pregnant women. The high prevalence of anaemia observed in Kiboga district can be attributed to poverty and limited access to nutrition and health education information which lead to low uptake and utilization of the public-health intervention package to combat anaemia in pregnancy.

To determine whether cholera risk factor prevalence in the Dominican Republic can be explained by nationality, independent of other factors, given the vulnerability of many Haitians in the country and the need for targeted prevention. A cross-sectional, observational household survey (103 Haitian and 260 Dominican) was completed in 18 communities in July 2012. The survey included modules for demographics, knowledge, socioeconomic status, and access to adequate water, sanitation, and hygiene (WASH) infrastructure. Logistic regression assessed differential access to WASH infrastructure and Poisson regression assessed differences in cholera knowledge, controlling for potential confounders. Dominican and Haitian households differed on demographic characteristics. Haitians had lower educational attainment, socioeconomic status, and less knowledge of cholera than Dominicans (adjusted odds ratio [aOR] = 0.66; 95% confidence interval [95%CI] = 0.55-0.81). Access to improved drinking water was low for both groups, but particularly low among rural Haitians (aOR = 0.21; 95%CI: 0.04-1.01). No differences were found in access to sanitation after adjusting for sociodemographic confounders (aOR = 1.00; 95%CI: 0.57-1.76). Urban/rural geography and socioeconomic status play a larger role in cholera risk factor prevalence than nationality, indicating that Haitians' perceived vulnerability to cholera is confounded by contextual factors. Understanding the social dynamics that lead to cholera risk can inform control strategies, leading to better targeting and the possibility of eliminating cholera from the island.

Objectives Noise is known to be one of the environmental and occupational hazards listed in the Factory and Machinery Act 1967. Quarries with loud deafening sounds from trucks and machineries pose the risk of noise-induced hearing loss to workers. This study was designed to assess the knowledge, attitude and practice towards noise-induced hearing loss and to determine the prevalence of noise-induced hearing loss and its associated factors among quarry workers in a north-eastern state of Malaysia. Methods A cross-sectional study was conducted at six quarries in a north-eastern state of Malaysia, with 97 consented respondents who answered a validated version of a questionnaire and underwent pure tone audiogram. The respondents were male, aged between 18 to 50 years, working in the quarry area for at least 6-months duration with no family history of ear diseases. Results The mean percentage scores of knowledge, attitude and practice were 44 (11), 70 (10) and 28 (16) percent, respectively. The prevalence of noise-induced hearing loss was found to be 57 (95% CI: 47, 67) with 46 (84%) having mild and moderate noise-induced hearing loss, and 34 (62%) involved both ears. Multiple logistic regressions showed that age and practice score were the associated factors with odd ratios of 1.1 (95% CI: 1.1, 1.2; p<0.001) and 0.9 (95% CI: 0.8, 1.0; p=0.008), respectively. Conclusion The knowledge, attitude and practice scores of the respondents were poor and the high prevalence of noise-induced hearing loss was contributed by factors such as poor practice and old age.

Cigarette smoking remains a major preventable public health problem associated with premature deaths worldwide. Adolescence is a unique developmental stage between childhood and adulthood. Smoking is a lifestyle habit acquired during adolescence and into adulthood, with its associated morbidity and mortality. It is therefore important to determine the factors associated with cigarette smoking in these adolescents in order to institute preventive measures and health policies to protect these adolescents early. This study aims to determine the prevalence of smoking, factors associated with smoking, and knowledge of the harmful effects of smoking in these adolescents. A cross-sectional study of 1120 adolescents aged 10-19 years selected from 10 secondary schools in Port Harcourt was conducted using a multistage sampling technique. The Global Youth Tobacco Survey (GYTS) core questionnaire was used to collect data from the subjects. A smoker was defined as one who had ever smoked a cigarette or who had one or two puffs, while a current smoker was defined as one who had taken a puff or smoked cigarettes in the last 30 days preceding the day of the questionnaire's completion. Eighty subjects (7.1%) were smokers. This was significantly (p=<0.001) higher in males (9.7%) than in females (4%). Thirty seven (3.3%) subjects were current smokers. The mean age at which smoking was initiated was 12.47±3.0 years. Twenty six (32.5%) of the smokers reported that they were initiated into cigarette smoking by their friends, 36 (45%) just wanted to experiment, 7 (8.8%) were influenced by media advertisements while 5 (6.3%) were due to parental exposure. Parental history of smoking and poor knowledge of cancer of the lungs as a harmful effect of smoking, was significantly (p=<0.05) associated with cigarette smoking. The prevalence of smoking in adolescents in Port Harcourt is high and is associated with parental smoking and poor knowledge of cancer of the lungs as a harmful effect. We recommend that adolescent health education with an emphasis on the harmful effects of smoking be included in the curriculum of all secondary schools.

Tobacco use has been identified as the single biggest cause of inequality in morbidity. The objective of this study is to examine the role of social determinants on current tobacco use in thirteen low-and-middle income countries. We used nationally representative data from the Global Adult Tobacco Survey (GATS) conducted during 2008-2010 in 13 low-and-middle income countries: Bangladesh, China, Egypt, India, Mexico, Philippines, Poland, Russian Federation, Thailand, Turkey, Ukraine, Uruguay, and Viet Nam. These surveys provided information on 209,027 respondent's aged 15 years and above and the country datasets were analyzed individually for estimating current tobacco use across various socio-demographic factors (gender, age, place of residence, education, wealth index, and knowledge on harmful effects of smoking). Multiple logistic regression analysis was used to predict the impact of these determinants on current tobacco use status. Current tobacco use was defined as current smoking or use of smokeless tobacco, either daily or occasionally. Former smokers were excluded from the analysis. Adjusted odds ratios for current tobacco use after controlling other cofactors, was significantly higher for males across all countries and for urban areas in eight of the 13 countries. For educational level, the trend was significant in Bangladesh, Egypt, India, Philippines and Thailand demonstrating decreasing prevalence of tobacco use with increasing levels of education. For wealth index, the trend of decreasing prevalence of tobacco use with increasing wealth was significant for Bangladesh, India, Philippines, Thailand, Turkey, Ukraine, Uruguay and Viet Nam. The trend of decreasing prevalence with increasing levels of knowledge on harmful effects of smoking was significant in China, India, Philippines, Poland, Russian Federation, Thailand, Ukraine and Viet Nam. These findings demonstrate a significant but varied role of social determinants on current tobacco use within and across countries.

Malaria is endemic in 13 districts of Bangladesh. A baseline malaria prevalence survey across the endemic districts of Bangladesh was conducted in 2007, when the prevalence was reported around 39.7 per 1000 population. After two rounds of Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM)-funded intervention by the National Malaria Control Programme (NMCP) and a BRAC-led NGO consortium, a follow-up survey was conducted across the malaria-endemic districts of Bangladesh to measure the change in prevalence rate and in people's knowledge of malaria. The survey was carried out from August to November 2013 in 70 upazilas (sub-districts) of 13 malaria-endemic districts of Bangladesh, following the same multi-stage cluster sampling design and the same number of households enrolled during the baseline prevalence survey in 2007, to collect 9750 randomly selected blood samples. For on-the-spot diagnosis of malaria, a rapid diagnostic test was used. The household head or eldest person available was interviewed using a pre-coded structured questionnaire to collect data on the knowledge and awareness of malaria in the household. Based on a weighted calculation, the overall malaria prevalence was found to be 1.41 per 1000 population. The proportion of Plasmodium falciparum mono-infection was 77.78% while both Plasmodium vivax mono-infection and mixed infection of the two species were found to be 11.11%. Bandarban had the highest prevalence (6.67 per 1000 population). Knowledge of malaria signs, symptoms and mode of transmission were higher in the follow-up survey (97.26%) than the baseline survey. Use of bed nets for prevention of malaria was found to be high (90.15%) at respondent level. People's knowledge of selected parameters increased significantly during the follow-up survey compared to the baseline survey conducted in 2007. A reduced prevalence rate of malaria and increased level of knowledge were observed in the present malaria prevalence survey in Bangladesh.

It is relevant to understand every aspect, regarding to strategies that will determine immunization coverage. Thus the main objective in this research is to identify the prevalence of depressive symptoms as well as low immunization uptake, identifying the caretakers' profile, considering his/her level of education, social-demographic character, marital status and also knowledge about immunization in which a Beck Inventory questionnaire was applied to the children's caretakers. Children's age ranged from 0 to 5 years and the number of subjects was 339 enrolled in a group of Family Health Strategy at the city of Cachoeirinha, in the state of Rio Grande do Sul, Brazil. The depression symptoms prevalence was 38.6%. The association between depression symptoms and the low immunization uptake was not statistical significant (OR=1.0, CI 95%, 0.62-1.73). The low immunization uptake rate was 23.3%. The high prevalence of depressive symptoms between mothers and the high percentage of immunization delay means the need of social help and the search of better effectivity of primary attention in health.

Egypt has by far the largest hepatitis C virus (HCV) prevalence in the world with 14.7% of the population being antibody positive for HCV. The aim of this study was to examine the association between knowledge of HCV and HCV antibody positivity among the Egyptian population. We characterized different measures of HCV knowledge and examined their associations with HCV prevalence, by analyzing a nationally representative database using standard epidemiologic methods. The database, the 2008 Egyptian Demographic and Health Survey, included demographic, health, and HCV biomarker information for a sample of over 12,000 individuals. Basic knowledge of HCV was found to be high, but multiple gaps were identified in the specific knowledge of HCV and its modes of transmission. There was no statistically significant difference in HCV prevalence between those who have heard of HCV infection and those who have not (14.4% vs. 15.9%, p>.05). Similar results were found for the other HCV knowledge measures including those specific to HCV modes of transmission and to the sources of information for HCV awareness. Logistic regression analyses did not demonstrate an association between HCV knowledge and HCV prevalence. Our results do not provide support for an effect of awareness on reducing the risk of HCV infection in Egypt. Public health messages directed at the lay public may not provide sufficient empowerment for individuals to avoid HCV infection, and should be complemented with prevention programs to promote and strengthen infection control in the settings of exposure, particularly in health care facilities.

As future health educators, nursing and physiotherapy students will play an essential role in the prevention of smoking. To determine the prevalence of smoking among students and to analyse their knowledge of and attitudes towards smoking. This was a descriptive cross-sectional study using an anonymous questionnaire and conducted in a Spanish Faculty of Health Sciences in 2013. 247 nursing and physiotherapy students (82.33%) participated in the study. The global prevalence of smoking (18.2%) was lower compare with the general population group of the same age. We have observed statistical significance in relation to previous studies. Nursing and physiotherapy students showed a low nicotine dependence. We found a lack of knowledge about the harmful effects of cigarette consumption on health. Statistically significant results were also found in relation to degree courses (p < 0.01) as regards students' opinions about their knowledge of strategies and methods to help patients stop smoking. Most students started smoking before commencing their university studies; consequently, interventions should focus on cessation programmes. An analysis of university curricula leading to the award of a degree in the health sciences could serve to identify educational deficiencies in order to implement the necessary modifications. This paper presents an update in tobacco use characteristics amongst nursing and physiotherapy students. Those results have showed a need to improve the curricula in order to develop specific programmes to improve knowledge, attitudes and beliefs. Measures to prevent smoking must be taken at school. © 2015 International Council of Nurses.

High job strain, mental stress, sedentary lifestyle, increase in BMI are among the factors associated with significantly higher incidence of hypertension. The job of bank employees is both sedentary in nature and accompanies high mental stress. The aim of this study is to assess the level of knowledge of risk factors among respondents and to compare the blood pressure pattern of bankers and traffic wardens. The study design is a descriptive cross-sectional conducted among bankers and traffic wardens in Ilorin to determine the pattern and knowledge of blood pressure. Self-administered questionnaires, weighing scale (Omron Digital scale), stadiometer and sphygmomanometer were used as the research instruments. Simple random sampling was used to select respondents involved in the study. The prevalence of hypertension in this study was 34.4% in bankers and 22.2% in traffic wardens. The risk factors the bankers commonly had knowledge of are alcohol, obesity, high salt intake, certain drugs, stress, emotional problems and family history while the traffic wardens commonly had knowledge of all these in addition to cigarette smoking. Also, more bankers (32.2%) than traffic wardens (13.3%) were smoking cigarette and more of these cigarette smokers that are bankers (17.8%) had elevated blood pressure compared to the traffic wardens (3.3%). Workers in the banking industry as well as traffic wardens should be better educated about the risk factors of hypertension and bankers should be encouraged to create time for exercise.

Soil-transmitted helminths (STH) are among the most important groups of infectious agents responsible for physical and intellectual growth retardation in children worldwide. Current status is need requiredfor the development of control programs. To determine the STH infections among the schoolchildren in the Mekong River basin near rural Ubon Ratchathani, Thailand and Champassak, Laos PDR, including their caregiver knowledge and attitude concerning prevention of STH infections. A cross sectional survey was designed as a home healthcare programfrom October 2009 to April 2012. 1,957 fecal samples were collected from children aged 5-12 years in five districts of Ubon Ratchathani province (1,012 fecal samples; Khong Chiam, Si Mueang Mai, Phibun Mangsahan, Sirindhorn, and Pho Sai), Thailand, and one district of Champassak Province (945 fecal samples; Pakse), Lao PDR. Fecal samples were prepared by the modified formalin ethylacetate concentration technique, and determined by light microscope. The knowledge and attitude of children's caregivers concerning prevention of soil-transmitted helminth infections were completed interviewed by semi-structured questionnaires. The overall intestinal helminth prevalence rate was 11.88%. Classified by species the STHs were as follows: Ascaris lumbricoides (30.9%), Trichuris trichiura (21.7%), and hookworm (20.5%). The highest prevalence was recorded in children aged 9 years and above. The highest prevalence of STH infection was found in the Pakse district of Laos PDR (16.08%). The intensities of infection with A. lumbricoides, T trichiura, and Hookworm were 1.82 ± 0.36, 1.32 ± 0.30, and 1.29 ± 0.32, respectively. 1,077 of caregivers were completed interviewed and found that the caregivers had fair levels of knowledge and attitude regarding soil-transmitted helminthiasis. These results suggest that priority should be given to STH eradication, the development of control programs in the Mekong River Basin, and the provision of education about STH to caregivers to reduce the risk of STH infection in their schoolchildren.

This study sought to determine the prevalence of common bacterial sexually transmitted infections, including Chlamydia trachomatis and Neisseria gonorrhoeae, in women attending clinics in the Solomon Islands. We conducted a sexual health survey among women attending three nurse-led community outpatient clinics in August 2014, to establish the prevalence of bacterial sexually transmitted infections in female clinic attenders in Honiara, Solomon Islands. Vaginal swab samples were tested for infection with C. trachomatis and N. gonorrhoeae using a commercial strand displacement amplification assay. Serum samples were tested for syphilis. We enrolled 296 women, aged 16-49, attending three clinics. Knowledge of safe sexual practices was high but reported condom usage was low. The prevalence of infection with C. trachomatis was 20%. The prevalence of infection with N. gonorrhoeae and syphilis were 5.1% and 4.1%, respectively. Bacterial sexually transmitted infections are a major health problem in the Solomon Islands. Interventions are urgently needed. Published by the BMJ Publishing Group Limited.

The aim of this study was to determine the prevalence of use of hearing aids by older adults in Chile and the influence of some variables such as education level, income level and geographic area of residence on the prevalence of hearing aids. A national cross-sectional survey which was carried out in 2009. A representative sample of 4766 Chilean older adults aged 60 years and above. The percentage of older adults in Chile who self-reported hearing problems and used hearing aids was 8.9%. Such prevalence increased for adults living in urban areas and for those who knew about the new Chilean programme of universal access to health services (AUGE). For older adults who did not know about this programme, significant associations between the use of hearing aids and the variables of age, geographic area of residence, and income level were found. People's knowledge about AUGE programme may positively influence the use of hearing aids, although a direct effect cannot be attributed.

The objectives of the study are to estimate the prevalence of left-hand dominance among children of selected mothers in an urban city and to determine the mothers' stereotypes about left-handedness. A cross-sectional study of mothers (N = 222) selected by systematic random sampling was done. The mothers were interviewed with structured questionnaires. Data were analyzed with appropriate descriptive statistics on SPSS. The estimated prevalence of left-hand dominance in their children was 7.52%. A left-handed mother was more likely to have a left-handed child. A substantial number of the mothers held negative stereotypes about left-hand dominance and showed a good knowledge about other types of handedness with a significant difference in the responses between right-handers and left-handers. The prevalence of left-hand dominance in their children supports previous reports which show that left-handedness usually occurs in less than 10% of the population. The mothers' negative stereotypes signify the likelihood of stigmatizing the children with this hand dominance.

This study explored the intervention effect of the "Nutrition on the Go" strategy on the prevalence of overweight and obesity (OW+O), according to the role played by different patterns. Pattern Groups (PG) were determined based on schools' food availability and other variables at individual level: nutrition knowledge, physical activity, socioeconomic level and self-efficacy, using an ecological approach. The PG classification was achieved using Ward's cluster method. The prevalence of OW+O was higher in PGI (intermediate food availability and high socioeconomic index [SEI]) compared to PG 2 (high availability of food and lower SEI) and PG 3 (low availability of food and medium SEI) with a lower prevalence (p<0.00I). The PG-intervention interaction showed differences for PG 3 (p=0.066), the stage-PG interaction showed differences between PGs I and 3 (p=0.014) and between PGs 2 and 3 (p=0.055). Differences between PGs have important implications for the prevalence of OW+O.

There is a scarcity of research into the use of non-physician-sourced cross-sex hormones in the transgender population. However, when medication is not prescribed by health professionals, users' knowledge of such medication may be adversely affected. This study aims to define the prevalence of Internet-sourced sex hormone use in a population attending for initial assessment at a gender identity clinic, to compare the prevalence between gender-dysphoric men and women, and to compare knowledge of cross-sex hormone side effects between users who source cross-sex hormones from medical doctors and those who source them elsewhere. In the first part of the study, a cross-sectional design is used to measure the overall prevalence of sex hormone use among individuals referred to a gender clinic. The second part is a questionnaire survey aiming at measuring sex hormone knowledge among individuals referred to this clinic. Main outcome measures were (i) categorical data on the prevalence and source of cross-sex hormone use and (ii) knowledge of sex hormone side effects in a population referred to a gender clinic. Cross-sex hormone use was present in 23% of gender clinic referrals, of whom 70% sourced the hormones via the Internet. Trans men using testosterone had a sex hormone usage prevalence of 6%; one-third of users sourced it from the Internet. Trans women had a sex hormone usage prevalence of 32%; approximately 70% of users sourced hormones from the Internet. Cross-sex hormone users who sourced their hormones from physicians were more aware of side effects than those who used other sources to access hormones. One in four trans women self-prescribe cross-sex hormones before attending gender clinics, most commonly via the Internet. This practice is currently rare among trans men. Self-prescribing without medical advice leaves individuals without the knowledge required to minimize health risks. © 2014 International Society for Sexual Medicine.

The Tangled Tale of Genes and Environment: Moore's The Dependent Gene: The Fallacy of “nature VS. Nurture”

Nature–nurture views that smack of genetic determinism remain prevalent. Yet, the increasing knowledge base shows ever more clearly that environmental factors and genes form a fully interactional system at all levels. Moore's book covers the major topics of discovery and dispute, including behavior genetics and the twin studies, developmental psychobiology, and developmental systems theory. Knowledge of this larger life-sciences context for behavior principles will become increasingly important as the full complexity of gene–environment relations is revealed. Behavior analysis both contributes to and gains from the larger battle for the recognition of how nature and nurture really work.

Internal tremor (IT) is a poorly recognized symptom that has been described in Parkinson's disease (PD). Described as a feeling of tremor in the extremities or trunk without actual movement, ITs are not debilitating but can be bothersome to patients. The origin of the sensation is unknown., and ITs may be prevalent in other diseases than PD. The present study sought to expand knowledge about IT by confirming their presence in PD, and determining their prevalence in Multiple Sclerosis (MS), and Essential Tremor (ET). A survey was developed in order to determine the prevalence of IT in PD, MS, and ET and to learn what associations with various disease characteristics were present. The survey was administered to 89 consecutive PD, 70 MS, and 11 ET patients. ITs were found to be a prevalent symptom in all three disorders (32.6% of PD, 35.9% of MS, and 54.5% of ET subjects reported experiencing ITs). ITs were found to be associated both with the subjects' perceived levels of anxiety and the presence of visible tremors. ITs appear to be a common symptom in all three disorders studied. These results need to be confirmed and compared to appropriate control populations. Copyright © 2015. Published by Elsevier Ltd.

Bacterial vaginosis (BV) is a vaginal disorder which occurs either symptomatic or asymptomatic because of an imbalance between H 2 O 2 -producing Lactobacillus and Gardnerella vaginalis in the vagina. This systematic review and meta-analysis is the first to determine the prevalence of BV in pregnant and non-pregnant women in Iran. We used national (SID, Irandoc, Iranmedex and Magiran) and international (PubMed, Scopus, Google Scholar and ISI web of knowledge) electronic databases to systematically search and collect available studies using related keywords (up to 1 December 2017). Inclusion and exclusion criteria were defined to select eligible studies. The overall prevalence of BV among Iranian women was 18.9% (95% CI 14-25). Gardnerella vaginalis was the most prevalent isolated bacteria. The prevalence of BV in non-pregnant women was 28% (95% CI 15.1-45.9) which was higher compared with pregnant women who had a prevalence of 16.5% (95% CI 12.5-21.6). The present review revealed a high prevalence of BV in non-pregnant women. Given that BV is associated with a series of reproductive complications such as infertility, taking preventive measures such as awareness of patients as well as monitoring and controlling of syndrome are essential.

Despite the large population of stray dogs in Thailand, there is limited information on the prevalence of canine vector-borne diseases (CVBDs). In this study, a molecular survey was conducted to determine the prevalence of Babesia spp., Ehrlichia canis, Hepatozoon spp., Anaplasma platys and Mycoplasma spp. in dogs in Thailand. Of the 181 dog blood samples tested by PCR, 78/181 (43.1%) were found to be infected with one or more pathogens. The overall prevalence rates of Mycoplasma spp., Hepatozoon spp., Babesia spp., A. platys and E. canis infections were 19.9%, 18.8%, 9.4%, 4.4% and 3.9%, respectively. To the authors' knowledge, this is the first report of Mycoplasma infection in Thailand in dogs. The current findings are important for future surveillance of CVBDs and designing appropriate approaches for diagnosis and control for the diseases in Thailand. Copyright © 2016 Elsevier Ireland Ltd.

An increase in prevalence of hypertension has been observed in all ethnic groups in India. The objective of the present study was to estimate prevalence and determinants of hypertension among tribals and their awareness, treatment practices and risk behaviours in nine States of India. A community based cross-sectional study adopting multistage random sampling procedure was carried out. About 120 Integrated Tribal Development Authority villages were selected randomly from each State. From each village, 40 households were covered randomly. All men and women ≥ 20 yr of age in the selected households were included for various investigations. A total of 21141 men and 26260 women participated in the study. The prevalence of hypertension after age adjustment was 27.1 and 26.4 per cent among men and women, respectively. It was higher in the s0 tates of Odisha (50-54.4%) and Kerala (36.7-45%) and lowest in Gujarat (7-11.5%). The risk of hypertension was 6-8 times higher in elderly people and 2-3 times in 35-59 yr compared with 20-34 yr. Only <10 per cent of men and women were known hypertensives and more than half on treatment (55-68%). Men with general and abdominal obesity were at 1.69 (CI: 1.43-2.01) and 2.42 (CI: 2.01-2.91) times higher risk of hypertension, respectively, while it was 2.03 (CI=1.77-2.33) and 2.35 (CI 2.12-2.60) times higher in women. Those using tobacco and consuming alcohol were at a higher risk of hypertension compared with the non users. The study revealed high prevalence of hypertension among tribals in India. Age, literacy, physical activity, consumption of tobacco, alcohol and obesity were significantly associated with hypertension. Awareness and knowledge about hypertension and health seeking behaviour were low. Appropriate intervention strategies need to be adopted to increase awareness and treatment practices of hypertension among tribals.

Research, policy, and programmatic considerations from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project

The Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project sought to inform the interpretation of iron and vitamin A biomarkers (ferritin, serum transferrin receptor, and retinol binding protein) in settings of prevalent inflammation as well as the prevention of and control strategies to address anemia. Our purpose is to comment on the contributions of the BRINDA to advance global knowledge with regard to iron and vitamin A status assessment in women and preschool children and to analyze the findings in terms of their rigor and usefulness for global nutrition research and programs. BRINDA investigators found that the acute-phase response is so prevalent that it must be assessed in surveys of iron and vitamin A status for valid interpretation of micronutrient biomarkers. Furthermore, they found that C-reactive protein and α-1-acid glycoprotein provide important and different information about these responses and that common survey variables cannot replace the information they provide. Developing a method for adjusting micronutrient biomarkers for the independent influence of inflammation is challenging and complex, and BRINDA has brought greater clarity to this challenge through the use of large and diverse data sets. When comparing approaches, the regression methods appear to perform best when sample sizes are sufficient and adequate statistical capacity is available. Further correction for malaria does not appear to materially alter regression-adjusted prevalence estimates. We suggest that researchers present both adjusted and unadjusted values for the micronutrient biomarkers. BRINDA findings confirm that iron deficiency is a common and consistent risk factor for anemia globally and that anemia control must combine iron interventions with control of infection and inflammation. Anemia control strategies must be informed by local data. By applying the knowledge in these studies, researchers, program planners, and evaluators working in populations with prevalent inflammation can use and interpret biomarkers with more confidence, tempered with necessary caution.

Migration has been linked to the spread of HIV epidemic from the urban areas of western India to the rural areas of north India. This is the first population-based study among the wives of migrant workers of Muzaffarpur district in Bihar with objectives to describe their sexual behavior within marriage, estimate the prevalence of HIV, and to know their awareness regarding HIV/AIDS. A two-stage cluster survey was conducted by randomly selecting 25 eligible wives from each of the 34 selected villages. A total of 850 wives were interviewed and the blood samples were collected for HIV testing. To determine the factors associated with HIV/AIDS-awareness, we calculated adjusted odds ratios and 95% confidence intervals (CI) using multiple logistic regression analysis. 34 (3%) of 850 wives reported condom use with their husband. HIV prevalence was 0.59% (95% CI: 0.19-1.37%) among the wives of migrant workers. Out of 850 wives, 132 (15.5%) had heard about HIV. Condoms use (OR = 3.21, 95% CI: 1.22-7.90) and premarital sex (OR=7.44, 95% CI: 1.6-33.67) were found significantly positively associated with HIV knowledge of wives. HIV awareness of the wives was significantly associated with age-group 15-24 years, literacy status, and possession of television and husbands' literacy status. The knowledge about HIV among wives had significant positive impact on condoms use and premarital sex. HIV prevalence among the wives of migrant workers was higher than the prevalence among women in the general population. Education was found to be positively associated with awareness about HIV. Effective interventions are needed for increasing awareness of HIV among wives of migrant workers in Bihar.

The aim of this study is to determine the knowledge, attitude, behaviour and practices regarding HIV/AIDS among the fishermen community in the coastal areas of Balochistan. A cross-sectional survey. This study was conducted between September-October 2000 at Gidani, a coastal area of Balochistan. About 1000 fishermen were interviewed to assess the knowledge, attitude, behaviour and practices regarding HIV/AIDS. It was a community based survey involving the key informants, interviews and focused group discussions. There was little awareness regarding causes and prevention of HIV/AIDS in the community. While healthcare providers believe that the prevalence of HIV/AIDS is high, the community did not consider themselves at risk. Adolescents with any sexual health problems visit hakims and quacks. The community was aware of the etiology and some of the risk factors associated with AIDS, most probably due to the recent public health campaigns against the disease. Considering the suspected high prevalence of HIV/AIDS and the relative lack of knowledge, it is imperative that a public health intervention program be initiated in these areas. This must include educating not only the community but also the health workers. The Government's initiative to train community workers in reproductive health is a step in the right direction.

Prevalence, sociodemographic factors, psychological distress, and coping strategies related to compulsive buying: a cross sectional study in Galicia, Spain.

Compulsive buying has become a serious problem affecting a growing number of people in contemporary consumer societies. Nevertheless, research examining its prevalence in representative samples from the general population is still scarce and mainly focused on the exploration of sociodemographic factors, neglecting other aspects like psychological distress and coping styles. Therefore, this study intends to contribute to the cumulative knowledge by assessing compulsive buying prevalence in a representative sample from the general population in the region of Galicia, in Spain. Sociodemographic determinants, psychological symptoms, and coping strategies are also analyzed to clarify their role in this phenomenon. A random routes procedure was employed in the recruitment of the sample which was comprised of 2159 participants who were classified as either compulsive buyers or non-compulsive buyers. Both groups were compared regarding sociodemographic determinants, symptoms, and coping strategies through chi-square tests or analyses of variance. A multivariate logistic regression analysis was conducted to determine which of these determinants might play a part in the make up of a risk profile for compulsive buying. Estimated prevalence of compulsive buying was 7.1%. Compulsive buyers and non-compulsive buyers differed significantly in sex and age, with women and younger people showing a higher propensity for this phenomenon. Individuals with compulsive buying presented significantly higher scores on all the psychological symptoms considered. They also employed passive-avoidance coping strategies much more frequently and active strategies of problem solving and cognitive restructuring much less frequently. The logistic regression analysis results confirmed that being female, experiencing symptoms of anxiety, depression, and obsession-compulsion, and employing the passive-avoidance coping strategies of problem avoidance, wishful thinking, and self-criticism, all constituted risk factors for compulsive buying, whilst the increased age and the use of the active coping strategies of problem solving and cognitive restructuring were protection factors. Our findings revealed a substantial prevalence of compulsive buying. Additionally, the relevance of sociodemographic determinants, psychological distress, and coping strategies in this problem was confirmed. The establishment of a risk profile for compulsive buying based on these different sets of determinants would likely contribute to the development of more effective intervention programs.

Objectives: To investigate the prevalence, knowledge, and treatment of TIA in a Chinese adult population. Methods: We conducted a complex, multistage, probability sampling–designed, cross-sectional, nationwide survey of 98,658 Chinese adults in 2010. Possible TIA cases were first identified by symptoms recall or self-reported history of TIA through face-to-face interviews, and the final diagnosis was then made by expert neurologists through phone interviews or record review. Results: The age-standardized prevalence of TIA was 2.27%. Clinically, only 16.0% of the participants were diagnosed before the study. The prevalence of TIA was higher in women and in patients who were older, had less education, were current smokers, lived in rural or undeveloped areas, and had a history of stroke, hypertension, myocardial infarction, dyslipidemia, or diabetes. Based on the survey responses, approximately 3.08% of Chinese adults had knowledge of TIA. Among patients with TIA, only 5.02% received treatment and 4.07% received guideline-recommended therapy. Conclusions: TIA is prevalent and an estimated 23.9 million people in China may have experienced a TIA. Public knowledge on TIA is very limited. TIA appears to be largely undiagnosed and untreated in China. There is an urgent need to develop strategies to improve the identification and appropriate management of TIA. PMID:25957333

Objective This study aimed to investigate total and device-specific screen viewing (SV) and its determinants in children aged 2 years and below. Design Cross-sectional study conducted in February 2014. Setting Well-child clinics in Singapore national polyclinics. Participants Parents of children (Singapore citizens or permanent residents) aged 2 years and below were enrolled during routine clinic visits. Out of 794 eligible parent–child dyads, 725 (91.3%) provided informed consent and were included in the analysis. Main outcome measures Device-specific information on SV and determinants was ascertained using interviewer-administered survey questionnaires. The prevalence and duration of aggregate and device-specific SV were reported. Associations with potential determinants were investigated using multiple logistic regression analysis. A p value less than 0.05 was considered statistically significant. Results The prevalence of daily SV and SV ≥2 h/day constituted 53.5% and 16.3%, respectively. The majority of children aged 18–24 months (88.2%) engaged in daily SV. TVs and mobile devices were the most commonly used screen devices, followed by computers and video consoles. In multivariable analysis, younger child age, Chinese ethnicity and setting rules on time of SV were strongly and consistently associated with lower levels of any SV and SV ≥2 h/day. Parental knowledge of SV recommendations and less parental SV were additionally associated with lower levels of SV ≥2 h/day. The number of screen devices was not associated with children's SV. Conclusions In contrast to recommendations, SV prevalence in children aged less than 2 years is high and appears to increase steadily across age groups. TVs and mobile devices are most frequently used. Improving parental knowledge of SV recommendations, reducing parental SV and especially the implementation of strict rules on SV time could be successful strategies to reduce SV in young children.

Education of healthcare workers is a core element of multicomponent delirium strategies to improve delirium care and, consequently, patient outcomes. However, traditional educational strategies are notoriously difficult to implement. E-learning is hypothesised to be easier and more cost effective, but research evaluating effectiveness of delirium education through e-learning is scarce at present. Aim is to determine the effect of a nursing e-learning tool for delirium on: (1) in-hospital prevalence, duration and severity of delirium or mortality in hospitalized geriatric patients, and (2) geriatric nurses' knowledge and recognition regarding delirium. A before-after study in a sample of patients enrolled pre-intervention (non-intervention cohort (NIC); n = 81) and post-intervention (intervention cohort (IC); n = 79), and nurses (n = 17) of a geriatric ward (university hospital). The intervention included an information session about using the e-learning tool, which consisted of 11 e-modules incorporating development of knowledge and skills in the prevention, detection and management of delirium, and the completion of a delirium e-learning tool during a three-month period. Key patient outcomes included in-hospital prevalence and duration of delirium (Confusion Assessment Method), delirium severity (Delirium Index) and mortality (in-hospital; 12 months post-admission); key nurse outcomes included delirium knowledge (Delirium Knowledge Questionnaire) and recognition (Case vignettes). Logistic regression and linear mixed models were used to analyse patient data; Wilcoxon Signed Rank tests, McNemar's or paired t-tests for nursing data. No significant difference was found between the IC and NIC for in-hospital prevalence (21.5% versus 25.9%; p = 0.51) and duration of delirium (mean 4.2 ± SD 4.8 days versus 4.9 ± SD 4.8 days; p = 0.38). A trend towards a statistically significant lower delirium severity (IC versus NIC: difference estimate - 1.59; p = 0.08) was noted for delirious IC patients in a linear mixed model. No effect on patient mortality and on nurses' delirium knowledge (p = 0.43) and recognition (p = 1.0) was found. Our study, the first in its area to investigate effects of delirium e-learning on patient outcomes, demonstrated no benefits on both geriatric patients and nurses. Further research is needed to determine whether delirium e-learning nested within a larger educational approach inclusive of enabling and reinforcing strategies, would be effective.

Posttraumatic stress disorder (PTSD) is the most common consequence of traumatic experiences. The North Central Nigeria to which Plateau State belongs has witnessed many ethno-religious crises. While previous studies suggested a high prevalence of PTSD among students, to the best of our knowledge, no such study has been reported in Nigeria. The study aimed to determine the prevalence and correlates of PTSD among medical students in a university. Cross-sectional systematic random sampling was used to select 200 medical students. A two staged interview with questionnaire on sociodemographic variables, PTSD Checklist-Civilian Version, Impact of Event Scale, and Composite International Diagnostic Interview was carried out. SPSS Inc. Released 2007. SPSS for Windows, version 16.0. Chicago, SPSS Inc. was used for statistical analysis. Prevalence of PTSD among the students was 23.5%. Previous childhood trauma and personal experiences during the crisis were significantly associated with having PTSD. High prevalence rate of PTSD among medical students in Jos is an indicator of psychological consequences of the recurring crises on the inhabitants. There is a need for follow-up and counseling/trauma healing for those identified.

Taking Costs and Diagnostic Test Accuracy into Account When Designing Prevalence Studies: An Application to Childhood Tuberculosis Prevalence.

When planning a study to estimate disease prevalence to a pre-specified precision, it is of interest to minimize total testing cost. This is particularly challenging in the absence of a perfect reference test for the disease because different combinations of imperfect tests need to be considered. We illustrate the problem and a solution by designing a study to estimate the prevalence of childhood tuberculosis in a hospital setting. All possible combinations of 3 commonly used tuberculosis tests, including chest X-ray, tuberculin skin test, and a sputum-based test, either culture or Xpert, are considered. For each of the 11 possible test combinations, 3 Bayesian sample size criteria, including average coverage criterion, average length criterion and modified worst outcome criterion, are used to determine the required sample size and total testing cost, taking into consideration prior knowledge about the accuracy of the tests. In some cases, the required sample sizes and total testing costs were both reduced when more tests were used, whereas, in other examples, lower costs are achieved with fewer tests. Total testing cost should be formally considered when designing a prevalence study.

Susceptibility to smoke has been recognized as a strong predictor of smoking experimentation and taking up regular smoking habit. The identification of smoking susceptible individuals and its determinants is important in the efforts to reduce future smoking prevalence. The aims of this study are to estimate prevalence of susceptibility to smoke among adolescents, and identify factors associated with it. Cross sectional data was obtained from Global Youth Tobacco Survey conducted in three cities of Pakistan in year 2004. Study population consisted of students in grades, 8th, 9th, and 10th; aged 13 to 15 years. Secondary analysis using univariate and multivariate logistic regression analyses were performed to estimate the associations between smoking susceptibility and co-variates. Descriptive statistics were reported in proportions, and adjusted odds ratios with 95% confidence interval were used to report logistic regression analyses. Approximately 12% of nonsmoking students were found susceptible to smoking. Students, who were females (OR = 1.53, 95% CI [1.24-1.89]); whose parents (OR = 1.64, 95% CI [1.35-1.99]); or close friend smoked (OR = 2.77, 95% CI [2.27- 3.40]) were more susceptible to cigarette smoking. Students who had good knowledge about harmful effects of smoking (OR = 0.54, 95% CI [0.43-0.69]); and had access to anti-smoking media (OR = 0.73, 95% CI [0.59-0.89]) were less likely to be susceptible to smoking. Students who were females, had smoking parents, friends or exposure to newspaper/magazines cigarette marketing, were more susceptible to cigarette smoking among Pakistani adolescents. While knowledge of harmful effects of smoking and access to anti-smoking media served as protective factors against susceptibility to smoking.

Low-moisture foods (LMF) are increasingly implicated in outbreaks of foodborne illness resulting in a significant public health burden. To inform the development of a new Codex Alimentarius code of hygienic practice for LMF, we applied a rapid knowledge synthesis and transfer approach to review global research on the burden of illness, prevalence, and interventions to control nine selected microbial hazards in eight categories of LMF. Knowledge synthesis methods included an integrated scoping review (search strategy, relevance screening and confirmation, and evidence mapping), systematic review (detailed data extraction), and meta-analysis of prevalence data. Knowledge transfer of the results was achieved through multiple reporting formats, including evidence summary cards. We identified 214 unique outbreaks and 204 prevalence and 126 intervention studies. ‘Cereals and grains’ (n=142) and Salmonella spp. (n=278) were the most commonly investigated LMF and microbial hazard categories, respectively. Salmonella spp. was implicated in the most outbreaks (n=96, 45%), several of which were large and widespread, resulting in the most hospitalizations (n=895, 89%) and deaths (n=14, 74%). Salmonella spp. had a consistently low prevalence across all LMF categories (0-3%), while other hazards (e.g. B. cereus) were found at highly variable levels. A variety of interventions were investigated in small challenge trials. Key knowledge gaps included under-reporting of LMF outbreaks, limited reporting of microbial concentration data from prevalence studies, and a lack of intervention-efficacy research under commercial conditions. Summary cards were a useful knowledge transfer format to inform complementary risk ranking activities. This review builds upon previous work in this area by synthesizing a broad range of evidence using a structured, transparent, and integrated approach to provide timely evidence-informed inputs into international guidelines.

Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria) for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans), mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis), ticks (Rhipicephalus sanguineus, Ixodes sp.), and lice (Trichodectes canis); and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%). Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases.

Breastfeeding provides beneficial health outcomes for infants and their mothers, and increasing its practice is a national priority in many countries. Despite increasing support to exclusively breastfeed, the prevalence at 6 months remains low. Breastfeeding behavior is influenced by a myriad of determinants, including breastfeeding attitudes, knowledge, and social support. Effective measurement of these determinants is critical to provide optimal support for women throughout the breastfeeding period. However, there are a multitude of available instruments measuring these constructs, which makes identification of an appropriate instrument challenging. Research aim: Our aim was to identify and critically examine the existing instruments measuring breastfeeding attitudes, knowledge, and social support. A total of 16 instruments was identified. Each instrument's purpose, theoretical underpinnings, and validity were analyzed. An overview, validation and adaptation for use in other settings was assessed for each instrument. Depth of reporting and validation testing differed greatly between instruments. Content, construct, and predictive validity were present for most but not all scales. When selecting and adapting instruments, attention should be paid to domains within the scale, number of items, and adaptation.

This article presents elements to better understand health systems from the complety paradigm, innovative perspective that offers other ways in the conception of the scientific knowledge prevalent away from linear, characterized by the arise of emerging dissociative and behaviors, based on the intra and trans-disciplinarity concepts such knowledges explain and understand in a different way what happens in the health systems with a view to efficiency and effectiveness. The complexity paradigm means another way of conceptualizing the knowledge, is different from the prevalent epistemology, is still under construction does not separate, not isolated, is not reductionist, or fixed, does not solve the problems, but gives other bases to know them and study them, is a different strategy, a perspective that has basis in the systems theory, informatics and cybernetics beyond traditional knowledge, the positive logics, the newtonian physics and symmetric mathematics, in which everything is centered and balanced, joint the "soft sciences and hard sciences", it has present the Social Determinants of Health and organizational culture. Under the complexity paradigm the health systems are identified with the following concepts: entropy, neguentropy, the thermodynamic second law, attractors, chaos theory, fractals, selfmanagement and self-organization, emerging behaviors, percolation, uncertainty, networks and robusteness; such expressions open new possibilities to improve the management and better understanding of the health systems, giving rise to consider health systems as complex adaptive systems.

This study assessed knowledge, prevalence, associated factors and mechanisms of coping with stress among bankers in Lagos State. It was a descriptive cross sectional study. A two stage sampling technique was used to select two hundred and twenty seven (227) respondents. Data was collected using a structured self administered questionnaire. The analysis was done using Epi-info version 2002 software and Chi Square was used to determine association between variables at p value 0.05. Fischer's Exact test was used where Chi-square was not valid. The age range of respondents was between 20 and 49 years while the mean age was 31.3 +/- 5.0 years. Only 3.6% had good level of knowledge about stress, 42.2% had fair level while more than half of the respondents had poor level of knowledge about stress (54.3%). Majority (67.0%) of the respondents were moderately stressed while one quarter (24.7%) were highly stressed. Majority (92.4%) of the respondents used good coping mechanisms though 69.5% of the respondents also used bad coping mechanisms. A greater proportion of those who had poor knowledge about stress were stressed or highly stressed (p = 0.002). A statistically significant association was also found between the departments in the bank and level of stress of the respondents (p = 0.002). The prevalence of stress was high among the bank workers studied. It is recommended that effective stress management programmes are implemented to address the problem of stress among bank workers.

Abstract Background. Complete prevalence proportions illustrate the burden of disease in a population. This study estimates the 2010 complete prevalence of malignant primary brain tumors overall and by Central Brain Tumor Registry of the United States (CBTRUS) histology groups, and compares the brain tumor prevalence estimates to the complete prevalence of other common cancers as determined by the Surveillance, Epidemiology, and End Results Program (SEER) by age at prevalence (2010): children (0–14 y), adolescent and young adult (AYA) (15–39 y), and adult (40+ y). Methods. Complete prevalence proportions were estimated using a novel regression method extended from the Completeness Index Method, which combines survival and incidence data from multiple sources. In this study, two datasets, CBTRUS and SEER, were used to calculate complete prevalence estimates of interest. Results. Complete prevalence for malignant primary brain tumors was 47.59/100000 population (22.31, 48.49, and 57.75/100000 for child, AYA, and adult populations). The most prevalent cancers by age were childhood leukemia (36.65/100000), AYA melanoma of the skin (66.21/100000), and adult female breast (1949.00/100000). The most prevalent CBTRUS histologies in children and AYA were pilocytic astrocytoma (6.82/100000, 5.92/100000), and glioblastoma (12.76/100000) in adults. Conclusions. The relative impact of malignant primary brain tumors is higher among children than any other age group; it emerges as the second most prevalent cancer among children. Complete prevalence estimates for primary malignant brain tumors fills a gap in overall cancer knowledge, which provides critical information toward public health and health care planning, including treatment, decision making, funding, and advocacy programs.

Racial differences in secular changes in cardiovascular disease risk factor knowledge and behaviors were assessed among adults with low levels of education throughout a community-wide cardiovascular disease prevention program. Four independent cross-sectional telephone surveys were conducted with the random-digit-dialing technique in 1987, 1988, 1989, and 1991 in a biracial South Carolina community. Community-wide cardiovascular disease intervention programs were initiated in 1988 and continued through 1990. Changes in the prevalence of cardiovascular risk factor knowledge, dietary fat intake, leisure-time physical activity, smoking, and cholesterol screening behavior were compared between African-American and white respondents in a population subset with less than 12 years of education using analysis of covariance regression techniques. Mean intake of high fat foods was lower in 1991 than in 1987 among both white and African-American respondents; the trend for lower mean intake began in 1989 among African-American adults. Prevalence of the correct exercise knowledge was higher in 1988 than in 1987 for both groups, but this trend was maintained only among white respondents. However, prevalence of leisure-time physical activity did not change significantly between 1987 and 1991. Prevalence of cholesterol level knowledge and screening behavior increased over time among both groups; however, greater increasing trends between 1987 and 1991 were observed among white adults. Favorable secular changes in fat intake, exercise knowledge, cholesterol level knowledge, and cholesterol screening behavior were observed among both race groups during a time period that coincided with community-wide intervention efforts and messages. Greater changes in most of these behaviors and knowledge were observed among white adults suggesting that health behavior messages may not have reached all segments of this community.

Men who have sex with men (MSM) are at growing risk of HIV infection in many parts of the world; however, the epidemic has not been well explored among this population in most Arab countries. To estimate the prevalence of HIV and related risk behaviors among MSM in Yemen, we recruited 261 adult MSM from the port cities of Aden and Al-Hudaydah through venue- and facility-based sampling. Behavioral data were collected with a face-to-face questionnaire, and HIV status was determined by serological testing. HIV prevalence was 5.9 % (95 % CI 4.8-7.3). One-fourth (25.8 %, 95 % CI 20.7-31.5) had tested for HIV in the last year and received results; 27.8 % (95 % CI 22.5-33.7) had comprehensive knowledge about HIV; 20.0 % (95 % CI 15.8-25.0) reported condom use at last anal sex; and 31.4 % (95 % CI 25.9-37.3) reported that they or their sexual partner had a sexually transmitted disease symptom. Injecting drugs in the last year was reported by 0.8 % (95 % CI 0.1-9.2). Multiple risk behaviors, low HIV knowledge, few preventive behaviors, and HIV prevalence greater than 5 % denote a concentrated and potentially expanding HIV epidemic among MSM in Yemen. No time should be lost in intervening to prevent further expansion of the epidemic to levels already seen among MSM outside the Middle East.

To determine the prevalence, attitude and knowledge of self-medication amongst university students of Karachi, Pakistan. This cross-sectional, study was conducted from Jan-Feb 2007. A convenience sample was taken from 2 medical and 2 non-medical universities of the city of Karachi, Pakistan. Data was analyzed using SPSS v 14 and associations were tested using the Chi square test. Of the 572 participants (mean age=21 +/- 1.8 years, Male: Female ratio=1:1.5), 295 were medical and 277 were non-medical students. The prevalence of self-medication was 76%. Forty three percent students stated that they alter the regimen of prescribed medicines while 61.9% stated that they stop taking a prescribed medicine without consulting a doctor. The most common reason for self-medication was previous experience (50.1%) and the most common symptoms were headache (72.4%), flu (65.5%), and fever (55.2%). Commonly used medicines were analgesics (88.3%), antipyretics (65.1%) and antibiotics (35.2%). Eighty seven percent of students thought self-medication could be harmful and 82.5% students thought that it was necessary to consult a doctor before taking a new medicine. There was no significant difference between the self medication practices of medical and non medical students (p=0.8) Prevalence of self-medication is high in the educated youth, despite majority being aware of its harmful effects. There is a need to educate the youth to ensure safe practices. Strict policies need to be implemented on the advertising and selling of medications to prevent this problem from escalating.

Coronary artery disease (CAD) is a major public health problem worldwide. To our knowledge, there is no national data available from community based studies on prevalence of CAD in the Kingdom of Saudi Arabia (KSA). Therefore, we designed this study with the objective to determine the prevalence of CAD among Saudis of both sexes, between the ages of 30-70-years in rural as well as urban communities. Further, to determine the prevalence and clinical pattern of the major modifiable risk factors for CAD among the same population. This work is part of a major national study on CAD in Saudis Study (CADISS). This is a community based study conducted by examining subjects in the age group of 30-70-years of selected households during 5-year period between 1995 and 2000 in KSA. Data were obtained from history using a validated questionnaire, and electrocardiography. The data were analyzed to provide prevalence of CAD and risk assessment model. Nine hundred and forty-four subjects, out of 17232 were diagnosed to have CAD. Thus, the overall prevalence of CAD obtained from this study is 5.5% in KSA. The prevalence in males and females were 6.6% and 4.4% (P<0.0001). Urban Saudis have a higher prevalence of 6.2% compared to rural Saudis of 4% (P<0.0001). The following variables are found to be statistically significant risk factors in KSA: age, male gender, body mass index (BMI), hypertension, current smoking, fasting blood glucose, fasting cholesterol and triglycerides. The overall prevalence of CAD in KSA is 5.5%. A national prevention program at community level as well as high risk groups should be implemented sooner to prevent the expected epidemic of CAD that we are seeing, beginning. Measures are needed to change lifestyle and to address the management of the metabolic syndrome, to reduce modifiable risk factors for CAD. A longitudinal study is needed to demonstrate the importance of reducing modifiable risk factors for CAD in KSA.

The ecological conditions of Yucatan made it a suitable region for the acquisition of vector-borne diseases such as dengue, rickettsiosis, and Chagas disease. As the epidemiological burden of these diseases shows an alarming increase of severe cases, the early establishment of diagnosis and therapeutics by first-contact physicians is a critical step that is not being fulfilled due to several reasons, including poor knowledge. To determine the level of knowledge related to dengue, Chagas disease, and rickettsiosis among rural first-contact physicians of Yucatan. A survey was applied to 90 first-contact physicians from rural clinics of Yucatan, which included 32 items related to the diagnosis, treatment, and prevention of dengue, rickettsiosis, and Chagas disease. Answers were analyzed by central tendency statistics. Differences were observed among every category, however; diagnosis and therapeutics showed the lower values. Globally, 62.5% of respondents showed moderate knowledge, 37.5% poor knowledge, and 0% adequate knowledge. Results suggest that a strong campaign for a continuous diffusion of knowledge regarding these diseases is needed. In regions with high prevalence of these kinds of diseases, like Yucatan, the impact of these results on the epidemiological burden of these diseases must be evaluated.

Purpose To: 1) determine prevalence of heel-strike in a mid-size city marathon, 2) determine if there is an association between foot-strike classification and race performance, and 3) determine if there is an association between foot-strike classification and gender. Methods Foot-strike classification (fore-foot strike, mid-foot strike, heel strike, or split-strike), gender, and rank (position in race) were recorded at the 8.1 kilometer (km) mark for 2,112 runners at the 2011 Milwaukee Lakefront Marathon. Results 1,991 runners were classified by foot-strike pattern, revealing a heel-strike prevalence of 93.67% (n=1,865). A significant difference between foot-strike classification and performance was found using a Kruskal-Wallis test (p < 0.0001), with more elite performers being less likely to heel-strike. No significant difference between foot-strike classification and gender was found using a Fisher’s exact test. Additionally, subgroup analysis of the 126 non-heel strikers found no significant difference between shoe wear and performance using a Kruskal-Wallis test. Conclusions The high prevalence of heel-striking observed in this study reflects the foot-strike pattern of the majority of mid- to long-distance runners and more importantly, may predict their injury profile based on the biomechanics of a heel strike running pattern. This knowledge can aid the clinician in the appropriate diagnosis, management, and training modifications of the injured runner. PMID:23006790

With the social development and lifestyle transition, increasing trends of overweight and obesity prevalence are commonly reported worldwide. Data focusing on overweight and obesity trends in rural residents and rural-to-urban migrants in China are limited. This study aims to assess the changes and related factors of overweight and obesity in Yi farmers and migrants in southwest China from 2007 to 2015, and to assess the disparities in prevalence changes. Pseudo-panel data was obtained from two cross-sectional studies conducted in Sichuan province, southwest China in 2007 and 2015. Standardized prevalence of overweight and obesity were evaluated by direct method using the 2010 national census population as the standard. Prevalence differences of overweight and obesity were calculated in each group and compared between groups to evaluate the disparity in prevalence changes. Generalized linear mixed model was performed to determine factors related to overweight/obesity. Standardized prevalence of overweight increased in both groups (from 5.54 to 16.65% in Yi farmers, from 27.91 to 33.61% in Yi migrants). Standardized prevalence of obesity increased only in Yi farmers (from 0.37 to 3.13%). Prevalence difference of overweight in Yi farmers was higher than that in Yi migrants (11.11 vs. 5.70), but prevalence differences of obesity were not significantly different between Yi farmers and migrants. Prevalence of overweight and obesity in Yi farmers, and prevalence of overweight in Yi migrants increased from 2007 to 2015. Yi farmers were developing overweight at a greater pace than migrants. More attention should be paid to spread health knowledge and encourage healthy lifestyle in Yi people, especially Yi farmers.

This study aimed to assess the prevalence of cigarette smoking among medical students, and to determine their level of knowledge regarding risk associated with cigarette smoking and their attitude and behavior towards tobacco control strategies and policies. A stratified random sampling approach was used to select participants. A modified version of the the Global Health Professional Students Survey questionnaire was self-administered. Descriptive statistics were applied and comparisons were done using chi-square test. Multivariate logistic regression was used to obtain the significant determinants of smoking. A P < 0.05 was considered significant. A total of 250 students participated in the study with a response rate of 89.2%. The mean age (years) was 21.4 ± 3. Rate of ever smoking and current smoking was 9.6 and 1.2%, respectively. Age > 21, having a smoking father, and use of alcohol were significantly associated with ever smoking. Knowledge of smoking as a risk for emphysema was 72.8%, coronary artery disease 82.8%, stroke 68.8%, and low birth weight 76.4%. There were 103 (41.2%) students aware of antidepressant usage in smoking cessation. One hundred and ninety-five (78%) offered smoking cessation advice if a smoker had no smoking-related disease and did not seek their opinion about smoking, 68.8% affirmed to having adequate knowledge on smoking cessation, and 56.8% had received formal training on smoking cessation techniques. The ban on cigarette smoking in enclosed public places was supported by 92.4%. The prevalence of current cigarette smoking among medical students in Lagos is relatively low. Gaps exist in the level of knowledge of the students regarding risks of cigarette smoking, tobacco cessation strategies, and in their attitude and behavior towards offering tobacco cessation advice. There is need therefore to include formal training on tobacco control strategies at an early stage in the medical curriculum.

Evidence from high income countries shows mothers who are supplemented with folic acid in their periconceptional period and early pregnancy have significantly reduced adverse outcomes like birth defects. However, in India there is a paucity of data on association of birth defects and folic acid supplementation. We identified a few important questions to be answered using separate scientific methods and then planned to triangulate the information. In this paper, we describe the protocol of our study that aims to determine the association of folic acid and pregnancy outcomes like neural tube defects (NTDs) and orofacial clefts (OFCs). We decided to fill the gaps in knowledge from India to determine public health consequences of folic acid deficiency and factors influencing dietary and periconceptional consumption of folic acid. The proposed study will be carried out in five stages and will examine the questions related to folic acid deficiency across selected locations in South and North India. The study will be carried out over a period of 4 years through the hierarchical evidence-based approach. At first a systematic review was conducted to pool the current birth prevalence of NTDs and orofacial clefts OFCs in India. To investigate the population prevalence, we plan to use the key informant method to determine prevalence of NTDs and OFCs. To determine the normal serum estimates of folic acid, iron, and vitamin B12 among Indian women (15-35 years), we will conduct a population-based, cross-sectional study. We will further strengthen the evidence of association between OFCs and folic acid by conducting a hospital-based, case-control study across three locations of India. Lastly, using qualitative methods we will understand community and health workers perspective on factors that decide the intake of folic acid supplements. This study will provide evidence on the community prevalence of birth defects and prevalence folic acid and vitamin B12 deficiency in the community. The case-control study will help understand the association of folic acid deficiency with OFCs. The results from this study are intended to strengthen the evidence base in childhood disability for planning and policy initiatives.

In Iran, breast cancer is the most prevalent cancer in women and a major public health problem. A cross sectional study was carried out to determine knowledge on breast cancer and breast self- examination (BSE) practices of 384 females living in the city of Hamadan, Iran. A purposive sampling method was adopted and data were collected via face-to-face interviews based on a validated questionnaire developed for this study. Among respondents 268 (69.8%) were married and 144 (37.5%) of the respondents reported having a family history of breast cancer. One hundred respondents (26.0%) claimed they practiced BSE. Level of breast cancer knowledge was significantly associated with BSE practice (p=0.000). There was no association with demographic details (p<0.05). The findings showed that Iranian women's knowledge regarding breast cancer and the practice of BSE is inadequate. Targeted education should be implemented to improve early detection of breast cancer.

Campylobacter spp. are one of the most common causes of acute bacterial gastroenteritis in human beings which are transmitted mostly via food originating from animals. This study was conducted to determine the prevalence and antimicrobial resistance of Campylobacter spp. isolated from retail raw meats in Iran. From June 2008 to June 2009, a total of 722 raw meat samples from camel (n = 107), beef (n = 190), lamb (n = 225), and goat (n = 180) were purchased from randomly selected retail outlets in Isfahan and Yazd, Iran, and were evaluated for the presence of Campylobacter spp. In this study, 50 of the 722 meat samples (6.9%) were contaminated with Campylobacter spp. The highest prevalence of Campylobacter spp. was found in lamb meat (12.0%), followed by goat meat (9.4%), beef meat (2.4%), and camel meat (0.9%). The most prevalent Campylobacter spp. isolated from the meat samples was Campylobacter jejuni (84.0%); the remaining isolates were Campylobacter coli (16.0%). Susceptibilities of 50 Campylobacter isolates were determined for 10 antimicrobial drugs using the disk-diffusion assay. Resistance to tetracycline was the most common finding (68.0%), followed by resistance to ciprofloxacin (46.0%) and nalidixic acid (40.0%). All of the isolates were susceptible to erythromycin, gentamicin, and chloramphenicol. Significantly higher prevalence rates of Campylobacter spp. (p < 0.05) were found in the lamb meat samples taken in spring (20.0%) and summer (18.9%). To our knowledge, this study is the first report of the isolation of Campylobacter spp. from raw camel, lamb, and goat meat in Iran.

Background Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. Methods In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria) for ectoparasites and intestinal helminths. In addition, a questionnaire regarding knowledge and practices was applied to pet owners. Results Nine ectoparasite species belonging to four taxa and six intestinal helminth species were identified: fleas (Ctenocephalides canis, Pulex irritans, Tunga penetrans), mites (Demodex canis, Otodectes sp., Sarcoptes scabiei var. canis), ticks (Rhipicephalus sanguineus, Ixodes sp.), and lice (Trichodectes canis); and Toxocara canis, Ancylostoma sp., Trichuris vulpis, Dipylidium caninum, Taenidae and Strongyloides sp. Overall prevalence of ectoparasites was 60.4% and of intestinal helminths 68.4%. The occurrence of C. canis, R. sanguineus, T. canis, Ancylostoma sp. and T. vulpis was most common (prevalence 14.4% to 41.7%). Prevalence patterns in helminths were age-dependent, with T. canis showing a decreasing prevalence with age of host, and a reverse trend in other parasite species. Knowledge regarding zoonoses was very limited and the diseases not considered a major health problem. Treatment with antiparasitic drugs was more frequent in urban areas. Conclusion Parasites of importance for human health were highly prevalent in Nigerian dogs. Interventions should include health education provided to dog owners and the establishment of a program focusing on zoonotic diseases. PMID:19068110

To determine attitudes, opinions and knowledge of domestic violence among medical and nursing staff. We performed a descriptive study of prevalence using an ad hoc questionnaire. A random sample of 321 health professionals were asked about their opinions and knowledge of domestic violence and its relationship with health. A total of 287 health professions completed the questionnaire. Most (87.1%) considered that intimate partner violence was an important problem, but not a health issue. Sixty percent of the health professionals believed that they could play an important role in detecting patients in this situation. Knowledge about the management of this problem was low. Nursing professionals were more sensitive to this issue and better prepared than medical staff. Healthcare personnel are sensitive to the problem of intimate partner violence but do not consider this issue to be a health problem. Education about this phenomenon and its management is required.

A cross-sectional descriptive study was conducted with self-administered questionnaires among 368 Myanmar migrant workers to investigate the prevalence of and to determine the risk factors for musculoskeletal disorders (MSDs) in the Thai seafood industry. The results showed the prevalence of MSDs was 45.1% occurring in the last 7 days. Marital status, number of dependents, other health problems, working hours, repetitive hand movements, awkward posture of wrists, prolonged standing, and manual handling of heavy loads were found to be associated with MSDs. Multiple logistic regression indicated that the workers who were married, had more than two dependents, and had more exposure to awkward wrist postures were at significantly increased risk of MSDs. The study findings suggest the need for adequate knowledge of ergonomics and for awareness campaign programs focusing on prevention of MSDs, especially low back pain, to be initiated in industries for earlier detection of symptoms among seafood processing workers.

To determine factors associated with an unknown HIV serostatus among pregnant women admitted in labor to Mulago Hospital, Kampala, Uganda. In total, 665 pregnant women admitted to Mulago Hospital were interviewed about their sociodemographic characteristics, obstetric history, access to prenatal care, fears regarding HIV testing, and knowledge about modes of mother-to-child-transmission (MTCT). Knowledge of the HIV serostatus was assessed by self-report and verified by prenatal card review. The prevalence of unknown HIV serostatus at the time of labor was 27.1%. Factors associated with an unknown HIV serostatus included high parity (odds ratio [OR] 1.9; 95% confidence interval [CI], 1.16-3.14), preterm delivery (OR 2.60; 95% CI, 1.06-6.34), prenatal care at a private clinic (OR 12.87; 95% CI, 5.68-29.14), residence more than 5 km from the nearest prenatal clinic (OR 2.86; 95% CI, 1.18-17.9), high knowledge about MTCT (OR 0.25; 95% CI, 0.07-0.86), and fears related to disclosing the test result to the partner (OR 3.60; 95% CI, 1.84-7.06). The high prevalence of unknown HIV serostatus among women in labor highlights the need to improve accessibility to HIV testing services early during pregnancy to be able to take advantage of antiretroviral therapy.

Tricyclic Antidepressants

NASA Astrophysics Data System (ADS)

Schmidt, Gary J.

The use of tricyclic antidepressant drugs is becoming increasingly prevalent for the treatment of depressed patients. It has been suggested that, analogous to many other drug substances, the tricyclic drugs exhibit clinical effectiveness within a defined therapeutic concentration range (1-10). Very recently, both Dito (11) and Orsulak and Schildkraut (12) have summarized the usefulness of measuring serum concentrations of these drugs. These authors suggest that knowledge of the plasma concentrations of these drugs aid the physician in determining patient compliance and initiating the best possible drug treatment.

2014-01-01

Background Tobacco use in India is characterized by a high prevalence of smoking and smokeless tobacco use, with dual use also contributing a noticeable proportion. In the context of such a high burden of tobacco use, this study examines the regional variations, and socioeconomic, demographic and other correlates of smoking, smokeless tobacco and dual use of tobacco in India. Methods and Findings We analyzed a cross sectional, nationally representative sample of individuals from the Global Adult Tobacco Survey in India (2009–10), which covered 69,296 individuals aged 15 years and above. The current tobacco use in three forms, namely, smoking only, smokeless tobacco use only, and both smoking and smokeless tobacco use were considered as outcomes in this study. Descriptive statistics, cross tabulations and multinomial logistic regression analysis were adopted as analytical tools. Smokeless tobacco use was the major form of tobacco use in India followed by smoking and dual tobacco use. Tobacco use was higher among males, the less educated, the poor, and the rural population in India. Respondents lacking knowledge of health hazards of tobacco had higher prevalence of tobacco use in each form. The prevalence of different forms of tobacco use varies significantly by states. The prevalence of tobacco use increases concomitantly with age among females. Middle-aged adult males had higher prevalence of tobacco use. Age, education and region were found to be significant determinants of all forms of tobacco use. Adults from the poor household had significantly higher risk of consuming smokeless tobacco. Lack of awareness about the selected hazards of tobacco significantly affects tobacco use. Conclusions There is an urgent need to curb the use of tobacco among the sub-groups of population with higher prevalence. Tobacco control policies in India should adopt a targeted, population-based approach to control and reduce tobacco consumption in the country. PMID:25474196

Dental caries is one of the most prevalent chronic diseases affecting children in Sub-Saharan Africa. Previous studies show a higher prevalence of dental caries in children from low socio-economic status backgrounds. The purpose of this study was to determine the prevalence of dental caries among 12 year old children in urban and rural areas of Zimbabwe and establish preliminary baseline data. A descriptive cross-sectional study was conducted among 12 year old children at primary schools in Harare and Bikita district. A Pre-tested questionnaire was administered to elicit information from the participants on tooth cleaning, dietary habits and dental experience. Dental caries status was assessed using the DMFT index following World Health Organization (WHO) guidelines. Our results showed a high prevalence of dental caries in both urban (59.5%) and rural (40.8%) children. The mean DMFT in urban and rural areas was 1.29 and 0.66, respectively. Furthermore, our data showed a general lack of knowledge on oral health issues by the participants. There is high prevalence of dental caries among 12 years old school children in both urban and rural areas of Zimbabwe. This calls for early preventive strategies and treatment services. We recommend incorporation of oral health education in the elementary school curricula.

Prevalence, sociodemographic factors, psychological distress, and coping strategies related to compulsive buying: a cross sectional study in Galicia, Spain

PubMed Central

2014-01-01

Background Compulsive buying has become a serious problem affecting a growing number of people in contemporary consumer societies. Nevertheless, research examining its prevalence in representative samples from the general population is still scarce and mainly focused on the exploration of sociodemographic factors, neglecting other aspects like psychological distress and coping styles. Therefore, this study intends to contribute to the cumulative knowledge by assessing compulsive buying prevalence in a representative sample from the general population in the region of Galicia, in Spain. Sociodemographic determinants, psychological symptoms, and coping strategies are also analyzed to clarify their role in this phenomenon. Methods A random routes procedure was employed in the recruitment of the sample which was comprised of 2159 participants who were classified as either compulsive buyers or non-compulsive buyers. Both groups were compared regarding sociodemographic determinants, symptoms, and coping strategies through chi-square tests or analyses of variance. A multivariate logistic regression analysis was conducted to determine which of these determinants might play a part in the make up of a risk profile for compulsive buying. Results Estimated prevalence of compulsive buying was 7.1%. Compulsive buyers and non-compulsive buyers differed significantly in sex and age, with women and younger people showing a higher propensity for this phenomenon. Individuals with compulsive buying presented significantly higher scores on all the psychological symptoms considered. They also employed passive-avoidance coping strategies much more frequently and active strategies of problem solving and cognitive restructuring much less frequently. The logistic regression analysis results confirmed that being female, experiencing symptoms of anxiety, depression, and obsession-compulsion, and employing the passive-avoidance coping strategies of problem avoidance, wishful thinking, and self-criticism, all constituted risk factors for compulsive buying, whilst the increased age and the use of the active coping strategies of problem solving and cognitive restructuring were protection factors. Conclusions Our findings revealed a substantial prevalence of compulsive buying. Additionally, the relevance of sociodemographic determinants, psychological distress, and coping strategies in this problem was confirmed. The establishment of a risk profile for compulsive buying based on these different sets of determinants would likely contribute to the development of more effective intervention programs.

Triceps tendon injuries are reported to be very rare. To our knowledge, there have been no studies describing its prevalence or injury patterns on MR imaging. The purpose of this retrospective study was to determine the prevalence and patterns of triceps injuries based on a large series of consecutive MR examinations. Clinical correlation was obtained. From 801 consecutive elbow MR examinations over a 15-year period, 28 patients with 30 triceps tendon injuries were identified and graded as partial tendon tear and complete tendon tear. The patients' medical records were reviewed to determine age, gender, cause of tears, and management. The prevalence of triceps tendon injuries was 3.8%. There were 5 women and 23 men with partial or complete tears (mean age: 46.6 years; range: 2.7 to 75.1 years). The most common injury was partial tear, found in 18 patients. There were 10 patients with 12 complete tears (2 had re-torn following surgical repair). A tear was suspected in 12 out 28 (43%) patients prior to the MRI. The most common presenting symptom was pain. The most common cause was athletic injury (8 patients [29%], including weightlifting [2 patients]). Tendon tear was found to be a complication of infection in 6 patients, and in 3 patients the tears were a complication of steroid use. Thirteen tendon tears were surgically repaired (8 of these were complete tears). Triceps tendon injury is not as rare as commonly reported and may often be clinically underdiagnosed.

The primary objective of this study was to determine the prevalence of Metabolic Syndrome (MS) in people between 40-70 years of age in the province of Albacete (Spain). A population-based, cross-sectional study was made of people between 40-70 years of age in three representative municipalities of the province of Albacete. A total of 425 subjects were included, with a mean age of 53.1 years (95% CI: 52.3-54). Women represented 50.4% of the series and males 49.6%. All participants were subjected to general laboratory testing, physical examination and the measurement of anthropometric parameters. MS was defined according to the ATP-III criteria. Prevalence of MS and its distribution according to the different epidemiological characteristics were calculated. Total prevalence of MS was 20.9% (88/421), with a mean age of 57 years (95% CI: 55.1-59). Prevalence was seen to increase with age, reaching up to one-third of all subjects over 60 years. Significant differences were observed in relationship to a background of ischemic heart disease, ultrasensitive C-reactive protein elevation and the detection of microalbuninuria in MS subjects. Arterial hypertension and abdominal obesity were the most prevalent criteria in MS subjects. Taking into consideration the important co-morbidity of MS, knowledge of the prevalence and characteristics of the syndrome in our setting and its early identification and intervention targeted to the different factors underlying MS will contribute to reduce the number of cardiovascular events associated with the syndrome.

Chronic malnutrition is one of the major causes of morbidity and mortality among preschool children and the future productivity of nations. To understand the prevalence of chronic malnutrition and to identify the factors affecting height-for-age z-score (HAZ) among preschool children, a cross-sectional study was conducted among 380 randomly-selected children aged less than five years in Dhaka city, Bangladesh. Results of analysis of this study data revealed that the prevalence of stunting among preschool children in Dhaka city was 39.5%, with 25% severely stunted and 14% moderately stunted (p<0.001). Results of bivariate analysis revealed that socioeconomic and demographic factors were most significantly associated with the stunting of children. Children were found to be well-nourished if their parents had a tertiary-level education or higher and if the mother held a job and had good knowledge of nutrition. Well-nourishment of the children were also associated with the height of mothers (above 148 cm), good family educational background, normal birthweight, greater frequency of food intake (more than six times/day), and fewer fever episodes in the last six months. Results of multivariate linear regression models showed that height of mothers, birthweight of children, education of fathers, knowledge of mothers on nutrition, and frequency of feeding were the most significant factors that had an independent and direct influence on the stunting of children. To achieve the Millennium Development Goal target of 34% malnutrition prevalence by 2015, it is important to have specific government intervention to focus on the causes that directly influence the stunting of children.

Summary Introduction. Brucellosis is endemic in Nigeria and risk factors enhancing its transmission are prevalent. Methods. Following serological evidence of brucellosis and isolation of B. abortus from slaughtered cattle in Ibadan, Nigeria, we administered a semi-structured questionnaire to determine the prevalence and predictors of eating and selling bovine gravid uterus among 350 meat handlers from five major meat processing facilities. We conducted key informant interview for five leading traditional healers to document its use. Data were analyzed using Stata 12. Results. The prevalence of eating and selling gravid uterus were 29.7% and 40.3% respectively. Being meat/offal processor (OR=1.9, 95%CI: 1.11-3.3, P = 0.008) and not knowing that eating undercooked contaminated gravid uterus could expose humans to brucellosis (OR=19.5; 95%CI: 5.73-66.03; P = 0.000) were strong predictors of eating gravid uterus. Similarly, being adult (OR = 1.7, 95%CI: 1.08-2.57, P = 0.02) and inadequate knowledge of brucellosis as a preventable disease (OR = 0.03; 95%CI: 0.004-0.27, P = 0.001) predicted selling gravid uterus. Qualitative data from the traditional healers revealed using gravid uterus as special medicinal preparations to hasten parturition in overdue pregnancies, treat infertility and old age diseases in humans. Conclusions. We demonstrated a high prevalence of risk factors for brucellosis transmission, and some meat handlers' sociodemographic characteristics and brucellosis knowledge-based markers as predictors of these factors. The traditional healers' practices portend a challenge to the current brucellosis control strategy. These findings provide insights into designing all-inclusive health programmes aimed at controlling brucellosis spread in Nigeria and other similar settings in developing countries. PMID:27980381

BACKGROUND: There is limited knowledge concerning chronic bronchitis (CB) in Canadian Aboriginal peoples. OBJECTIVE: To determine the prevalence (crude and adjusted) of CB and its associated risk factors in Canadian Aboriginal children and youth six to 14 years of age. METHODS: Data from the cross-sectional Aboriginal Peoples Survey were analyzed in the present study. Logistic regression analysis was used to determine risk factors influencing the prevalence of CB among Aboriginal children and youth. The balanced repeated replication method was used to compute standard errors of regression coefficients to account for clustering inherent in the study design. The outcome of interest was based on the question: “Have you been told by a doctor, nurse or other health professional that you have chronic bronchitis?” Demographics, environment and population characteristics (predisposing and enabling resources) were tested for an association with CB. RESULTS: The prevalence of CB was 3.1% for boys and 2.8% for girls. Other significant risk factors of CB were age (OR 1.38 [95% CI 1.24 to 1.52] for 12 to 14 year olds versus six to eight year olds), income (OR 2.28 [95% CI 2.02 to 2.59] for income category <$25,000/year versus ≥$85,000/year), allergies (OR 1.96 [95% CI 1.78 to 2.16] for having allergies versus no allergies), asthma (OR 7.61 [ 95% CI 6.91 to 8.37] for having asthma versus no asthma) and location of residence (rural/urban and geographical location). A significant two-way interaction between sex and body mass index indicated that the relationship between the prevalence of CB and body mass index was modified by sex. DISCUSSION: The prevalence of CB was related to well-known risk factors among adults, including older age and lower annual income. PMID:23248806

Abuse of the injection services, namely unnecessary injections and unsafe injections, exists extensively in developing countries. Unsafe injection practices contribute to the transmission of blood-borne pathogens. The aims of this study were to survey the prevalence of injections and knowledge of injection safety among the rural residents in Jingzhou district, Hubei, China and to provide scientific data for developing a health educational programme. A retrospective cross-sectional study was conducted in 12 villages, which were selected from the Jingzhou district by the random sampling method. 50 rural residents were interviewed per village using a questionnaire. Among the 595 residents studied, 192 had received at least one injection in the past three months, with an injection prevalence of 32.3 percent and an average of 0.93 injections. 90.3 percent of the rural residents knew that unsafe injections could transmit the following blood-borne pathogens: human immunodeficiency virus (74.4 percent), hepatitis B virus (55.8 percent) and hepatitis C virus (22.9 percent). Logistic regression analysis showed that the residents' age, educational level and residential area were important factors in influencing their knowledge about injection safety. The results indicated that the injection prevalence was high among rural residents in the study area, and their knowledge regarding injection safety should be further improved.

In Ethiopia, knowledge of contraceptive methods is high though there is low contraceptive prevalence rate. This study was aimed to assess prevalence and associated factors of long acting and permanent contraceptive methods in Jinka town, southern Ethiopia. Community based cross sectional survey was conducted to assess the prevalence and factors affecting long acting and permanent methods of contraceptives utilization from March to April 2008. Eight hundred child bearing age women were participated in the quantitative study and 32 purposively selected focus group discussants were participated in the qualitative study. Face to face interview was used for data collection. Data were analyzed by SPSS version 13.0 statistical software. Descriptive statistics and logistic regression were computed to analyze the data. The prevalence of long acting and permanent contraceptive method was 7.3%. Three fourth (76.1%) of the women have ever heard about implants and implant 28 (50%) were the most widely used method. Almost two third of women had intention to use long acting and permanent methods. Knowledge of contraceptive and age of women have significant association with the use of long acting and permanent contraceptive methods. The overall prevalence of long acting and permanent contraceptive method was low. Knowledge of contraceptive and age of women have significant association with use of long acting and permanent contraceptive. Extensive health information should be provided.

Viet Nam is experiencing a shift in its burden of disease profile with injuries becoming more prominent. A history of high alcohol involvement in road traffic crashes despite stringent laws led to increased enforcement by police, enhanced public education messaging and targeted social marketing campaigns in Ha Nam and Ninh Binh provinces in Viet Nam. This study aims to illustrate the changes in prevalence (November 2010 to December 2011) and knowledge, attitudes and practices (KAP) around alcohol use and drink-driving for the year 2011. Breath Alcohol Concentration (BrAC) was collected through police enforcement checkpoints in the two provinces. The proportion of drivers with BrAC above the legal limit was plotted over time for both provinces. The trend in prevalence of drink-driving over time was further assessed using Poisson regression models. Prevailing KAPs were determined through surveying randomly selected road users over the age of 17 years at gas stations at quarterly intervals. Cross tabulations of key variables as well Chi-Square statistic were used to assess associations. A total of 8,404 drivers were tested for BrAC levels of which less than 0.25% were female. Of 1,639 drivers displaying BrAC levels in excess of the legal limit, 87.3% were car drivers, 7.9% motorcyclists and 86% were between the ages of 25 and 44 years. KAP surveys captured 1,661 drivers over the study period. The prevalence of self-reported drink-driving increased 6 percentage points among respondents aged 27-36. Between 44% (January 2011) and 49% (December 2011) of respondents indicated awareness of a drinking and driving Blood Alcohol Concentration (BAC) or BrAC limit and only 25% of all study participants recalled being penalized for a traffic violation - none of which were for drink-driving. While there has been some reduction in drink-driving prevalence, inadequate or incorrect knowledge on drink-driving legislation appears to be an impediment to greater gains. Increased attention needs to be paid to enforcement activities and social marketing campaigns need to be part of a multi-faceted programme that also works on improving existing legislation, takes into consideration gender issues, and enhances visible enforcement of the laws.

To determine the prevalence and barriers to human papillomavirus (HPV) vaccine uptake among 11-18 year olds in the Hawai'i's four major ethnic groups-Native Hawaiians, Filipinos, Japanese, and Caucasians. A telephone survey assessed parents' knowledge of HPV and the HPV vaccine, status of their child's HPV vaccine uptake, variables operationalizing the Health Belief Model, and barriers and motivators to uptake. Across the groups, 799 parents completed the survey. About 35% of daughters and 19% of sons had received all three shots. Although ethnic differences in vaccine uptake were seen in bivariate analysis (with significantly lower uptake in Filipino youth), in multivariable logistic regression analysis, only Caucasian parents were significantly less likely to start their sons on the HPV vaccine series compared with Japanese parents (reference group). Having heard about the vaccine, believing in its effectiveness, and older age of the child were also associated with vaccine uptake. Motivators for HPV vaccination were physician's recommendation and wanting to protect one's child. The primary barrier to uptake was lack of knowledge about the vaccine. Findings reinforce the fact that a physician's recommendation and receipt of information about the vaccine are strong motivators for parents to vaccinate their children, regardless of ethnicity.

Milling machine operators perform physically demanding tasks that can lead to work related musculoskeletal disorders (WRMSDs), but literature on WRMSDs among milling machine operators is scarce. Knowledge of prevalence and risk factors of WRMSDs can be an appropriate base for planning and implementing ergonomics intervention programs in the workplace. This study aimed to determine the prevalence, pattern and associated factors of WRMSDs among commercial milling machine operators in Enugu, Nigeria. This cross-sectional survey involved 148 commercial milling machine operators (74 hand-operated milling machine operators (HOMMO) and 74 electrically-operated milling machine operators (EOMMO)), within the age range of 18-65 years, who were conveniently selected from four markets in Enugu, Nigeria. A standard Nordic questionnaire was used to assess the prevalence of WRMSDs among the participants. Data were summarized using descriptive statistics. There was a significant difference (p = 0.001) related to prevalence of WRMSDs between HOMMOs (77%) and EOMMOs (50%). All body parts were affected in both groups and shoulders (85.1%) and lower back (46%) had the highest percentage of prevalence. Working in awkward and same postures, working with injury, poor workplace design, repetition of tasks, vibratory working equipments, reduced rest, high job demand and heavy lifting were significantly associated with the prevalence of WRMSDs. WRMSDs are prevalent among commercial milling machine operators with higher occurrence in HOMMOs. Ergonomic interventions, including the re-design of milling machines and appropriate work posture education of machine operators are recommended in the milling industry.

Taeniasis and cysticercosis are important but underreported parasitic zoonoses in the Lao People's Democratic Republic (Lao PDR). Reports of human and pig cysticercosis are rather limited and based largely on anecdotal evidence. To date, no structured surveys of disease prevalence or incidence have been reported. However, one unpublished pilot survey of pig cysticercosis in a slaughterhouse in northern Laos estimated prevalence to be 1.7%, without speciation of parasite cysts. Over the past 20 years, nine surveys of intestinal helminthic infection have been conducted; the prevalence of human taeniasis ranged from 0 to 14.0%. The study designs and sample sizes varied greatly, however a high degree of spatial and age variation in taeniasis prevalence was evident. These results are however inconclusive as the species of tapeworm infecting the people was not determined. To further our knowledge of taeniasis and cysticercosis in Lao PDR, structured community-based surveys in high-risk areas are required in combination with the use of sensitive and specific diagnostic tests capable of identifying the pork tapeworm, Taenia solium. This will enable the development and implementation of control measures that are both appropriate and sustainable if T. solium is shown to be a public health threat.

Studies have revealed high prevalence rates of Trichomonas vaginalis in men and women worldwide. In Brazil, where reporting is not mandatory, the true prevalence rate is unknown. This study determined the prevalence of the parasite in women attending public health units in the city of Uberlândia, Minas Gerais, Brazil, identifying possible risk factors for infection, and also compared three diagnostic techniques for detecting the parasite. Samples of vaginal secretions collected from 742 women attending public health units were analyzed by direct wet mount examination, culture and smear test. Epidemiological questionnaires were administered. Of the total of 742 samples analyzed, 19 (2.6%) tested positive for T. vaginalis. The variables significantly associated with infection were: being of black ethnicity, smoking, having knowledge about sexually transmitted diseases and presenting clinical signs. The culture method was considered the gold standard test. Although there are programs to control other sexually transmitted diseases, there are none for trichomoniasis. The results of this study indicate the presence of T. vaginalis in the female population, and points to the need for more research in Brazil to gain a better understanding of the profile and epidemiology of the parasite.

Since human papillomavirus (HPV) is the central casual factor in cervical cancer, understanding the epidemiology and geographical area distribution of the most prevalent HPV genotypes constitutes an important step towards development of strategies of prevention. The aim of this study was to investigate the prevalence of HPV infection and to determine HPV types distribution among 822 HPV positive women and some sexual male partners in Apulia (Italy). HPV DNA detection and genotyping was performed by nested-PCR for the L1 region and reverse line blot hybridization allowing the specific detection of 24 HPV genotyping both high risk (HR) and low risk (LR). The most prevalent HPV genotypes were HPV 16 (35%), HPV 31 (16%) HPV 6 (9%), HPV 58 and 66 (7%), followed by HPV 33 (6%), HPV 18 and 56 (4%), HPV 70 and 45 (3%), HPV 53 and 11 (2%). Currently 1.5% of tested specimens remained unclassified. Multiple infections with at last two different high- risk HPV genotypes were observed in 10% of specimens. This finding adds knowledge to HPV epidemiological investigation, and addresses further studies aimed to consider public health for identifying groups at risk for cervical cancer.

In Ethiopia national breastfeeding practice is poor because of traditional and cultural beliefs, low educational levels, heavy workload of mothers, poor sanitary conditions, type of assistance at delivery, duration of stay at home, ethnicity, poor maternal knowledge, age, parity, antenatal service utilization and place of delivery. This study is aimed to assess the prevalence and determinants of exclusive breastfeeding practice in mothers in Enderta woreda (district), Ethiopia. A community based cross-sectional study with multistage sampling method was used to select 541 mothers with children less than 24 months of age in Enderta woreda. Data was collected by administered structured questionnaire. Bivariate and Multivariable logistic regression was used to check the associations and controlling confounding variables. A total of 530 mothers were included with a response rate 98%. The mean (± SD) age of the mothers was 26.9 (± 5.98) years. Majority of the mothers (70.2%) were practiced exclusive breastfeeding. Age of the mother (AOR 0.12; 95% CI: 0.02, 0.97), age of the child (AOR 0.52 95% CI: 0.27, 0.99) and postnatal care (AOR; 2.68; 95% CI: 1.44, 4.98) were found statistically significant with exclusive breastfeeding. The prevalence rate of exclusive breastfeeding was high in Enderta woreda. The age of the mother, age of the child and receiving postnatal care were the determinant factors for exclusive breastfeeding in the study area.

The prevalence of colorectal cancer (CRC) among older people is high. Screening for CRC presents a cost-effective secondary prevention and control strategy which results in a significant reduction in mortality. This study aims to describe the prevalence of CRC screening and examine its risk factors among Chinese community-dwelling older people guided by a comprehensive model combining Health Belief Model and Extended Parallel Processing Model. A descriptive correlational study was conducted. A convenience sample of 240 community-dwelling adults aged ≥60 was recruited in May-July in 2012 in Hong Kong. Participants were asked to complete a questionnaire which collected information on demographic variables, CRC-related psychosocial variables and whether they had a CRC screening in the past 10 years. Among the participants, 25.4% reported having a CRC screening test. Results of logistic regression analyses indicated that participants with a higher level in cue to action, and lower perceived knowledge barriers and severity-fear were significantly associated with participation in CRC screening. But there were no significant associations between fatalism and cancer fear with screening. The prevalence of CRC screening was low in Hong Kong Chinese community-dwelling elders. A number of modifiable factors associated with CRC screening were identified which provides specific targets for interventions. This study also adds to the knowledge regarding the associations between fatalism and fear with CRC screening behaviors among Chinese older people. Copyright © 2015 Elsevier Ltd.

Adolescent girls' family context and psychological characteristics play important roles in their sexual behavior, including the use of the emergency contraceptive pill (ECP). This study aims to (1) determine the prevalence of ECP use among girls who have had sexual intercourse and (2) comparatively analyze their family and psychological profiles according to whether they have used ECPs. The sample of 1735 Spanish girls aged 15 to 18 came from a representative sample of the 2014 edition of the Health Behaviour in School-aged Children (HBSC) study. Of this sample, 398 girls had sexual intercourse and reported their ECP use. Data collection for the HBSC study was performed through an online questionnaire to which adolescents responded anonymously in school. Data analyses were descriptive and bivariate and were performed with the statistical program IBM SPSS Statistics 23. The results demonstrated that 30.65% of girls who had sexual intercourse used ECPs. Noticeable differences in paternal knowledge and communication with the father were observed between girls who used the ECP at least once and those who did not use it. In contrast, differences between girls who used the ECP once and those who used it twice or more were pronounced with regard to parental knowledge, communication with parents, maternal affection, life satisfaction, sense of coherence and depression. This work demonstrates a high prevalence of ECP use and a more positive family and psychological profile for girls who used ECP once compared with those who used it twice or more.

Background/ Objective: Diabetes mellitus is a non-communicable disease which has become a major global public health issue. This systematic review summarized epidemiological studies related to the prevalence, risk factors, complications, incidence, knowledge, attitude and practices of Diabetes Mellitus (DM) among Arab population in the United Arab Emirates (UAE). PubMed, Scopus databases, Science direct, Wiley online library, and other local journals were searched to identify relevant literature using appropriate keywords to retrieve studies conducted in the UAE. Search limits were restricted to studies in English language, between 2007 and 2016, and on UAE population (both citizens and expatriates). Electronic database search yielded 24 studies about the prevalence, incidence, complications, risk factors, knowledge, attitudes and practices of diabetes, including cross sectional studies (n =18), population-based survey (n = 1), retrospective cohort studies (n = 3), qualitative (n=1), and randomized controlled trial (n = 1). Countrywide prevalence estimates of Diabetes Mellitus were reported to be high. The major determinants of Diabetes Mellitus involved hypertension, physical inactivity, sedentary lifestyle, and unhealthy diet. Even though past evidences have promulgated the role of numerous causative factors, the epidemiological implications of some of the risk factors including family history, educational level, and the use of alcohol remains elusive. This systematic review signifies epidemiology of Diabetes Mellitus in the United Arab Emirates and suggests that extra efforts are needed for preventive and curative strategies in order to decrease the burden of this non-communicable disease.

Androgenic-anabolic steroids (AAS) are abused by a growing number of bodybuilders. This descriptive cross-sectional study was conducted to determine prevalence and patterns of AAS use by bodybuilders in Hamadan, western Iran. In this cross-sectional study, participants were recruited from five gym clubs in two area of Hamadan (a total of 10 clubs). Twenty-five bodybuilders from each club were administered. Questions investigating demographic information, sport history, education level, general knowledge about AAS, and their side effects were asked. Statistical analysis was performed using SPSS 16. The frequency of AAS use was 28.8% (72/250). Fifty-four percent of users were 25 years or younger. AAS abuse showed a significant association with duration of exercise. The drugs were suggested mostly from peers (43.1%) and coaches (36.1%). The most commonly consumed anabolic steroid was testosterone (66.7%). The most commonly reported AAS side effect was acne (18.1%). There was not significant association between general knowledge about side effects of ASS and their use. The results of current survey indicate that frequency of ASS use is high in adolescents and young adult bodybuilders. Well educated bodybuilders have a higher prevalence of abuse. Awareness about the side effects of drugs is not deterrent factor for their abuse. Iranian Ministry of Sport and the Youth, and the National Council for Youth, should be urged to conduct more effective prevention strategies.

The prevalence of extended-spectrum β-lactamase-producing Escherichia coli (ESBL-EC) has increased recently. The aim of this study was to further characterise and to assess the occurrence of ESBL-EC in Riyadh, to use pulsed field gel electrophoresis (PFGE) typing to investigate the epidemiology of ESBL-EC and to determine the prevalence of ST131 in ESBL-EC. A total of 152 E. coli isolates were collected at a tertiary hospital in Riyadh from September 2010 to June 2011. Genotypic and phenotypic methods were used to characterise ESBLs. PFGE was used to determine genetic relatedness. Detection of ST131 and CTX-M-like ESBLs was performed using real-time PCR. Of 152 strains, 31 were positive for ESBLs by phenotypic methods. The blaCTX-M-15 gene was highly prevalent (30/31 strains, 96.77%) among the 31 ESBL-positive E. coli strains. The blaCTX-M-27 gene was detected in one strain. Twenty (64.5%) out of 31 of ESBL-EC were ST131. PFGE revealed 29 different pulsotypes. Our study documented the high prevalence of ESBLs in E. coli isolates, with CTX-M-15 as the predominant ESBL gene. ST131 clone producing CTX-M-15 has a major presence in our hospital. The high prevalence of CTX-M producers was not due to the spread of a single clone. To the best of our knowledge, this study represents the first report of CTX-M-15 and CTX-M-27 β-lactamases and the detection of the ST131 clone in Saudi E. coli isolates.

In this study, we aimed to conduct a meta-analysis on the results of eligible studies to estimate the prevalence of asthma, COPD, and Chronic bronchitis in Iran. International and Iranian databases including PubMed, Scopus, Web of Science, Iranmedex, and scientific information database (SID) were searched for population-based studies that had reported the prevalence of asthma and COPD from 1990 to 2015. We conducted the meta-analysis using metaprop application of Stata statistical software. I-Squared was used for calculating heterogeneity among the studies. To determine causes of heterogeneity, subgroup analysis and meta-regression method were used. Based on the results of random effect method, the overall prevalence of asthma ever was 4.56% (3.76%-5.36%) among men while it was 4.17% (3.42%-4.91%) among women. Pooled prevalence of current asthma was 7.95% while confidence interval changed from 5.85% to 10.06% (men 5.83% (2.75%-8.92%), women 9.13% (3.35%-14.94%)). Also based on the results of random effect model pooled prevalence of chronic bronchitis of five studies was 5.57%. It seems that the total crude prevalence of current asthma in Iran is less than many other countries such as Kuwait, Lebanon, Thailand, Japan, Australia and Germany and is higher than some other countries such as Oman, Pakistan, South Korea, India, China, Taiwan, Indonesia, Spain, Russia, and Greece. On the other hand, Iran is in middle situation in terms of the prevalence current asthma. Our results can fill the information and knowledge gaps about the status of the prevalence of respiratory diseases in Iran.

Young girls in sub Saharan Africa are reported to have higher rates of human immunodeficiency virus (HIV) infection compared to boys in the same age group. Knowledge of HIV status amongst high schools learners provides an important gateway to prevention and treatment services. This study aimed at determining the HIV prevalence and explored the feasibility of HIV testing among high school learners. Between September 2010 and February 2011, a linked, anonymous cross-sectional survey was conducted in two public sector high schools in the rural KwaZulu-Natal midlands. Following written informed consent, dried blood spot samples (DBS) were collected and tested for HIV. The overall and age-specific HIV prevalence were compared with select demographic variables. The HIV prevalence in learners aged 12 to 25 in school A was 4.7% (95% CI 2.8-6.5) compared to 2.5% (95% CI 1.6-3.5) in school B, (p=0.04). Whilst the HIV prevalence was similar for boys at 1.3% (95% CI 0-2.8) in school A and 1.7% (95% CI 0.5-2.8) in school B, the prevalence in girls was consistently higher and was 7.7% (95% CI 4.5-10.9) in school A and 3.2% (95% CI 1.8-4.6) in school B. The age-specific HIV prevalence in girls increased 1.5 to 2 fold for each two year age category, while for boys the prevalence was stable across all age groups. The high HIV prevalence in female learners underscores the importance of sexual reproductive health and schools-based HIV testing programs as an important gateway to prevention and treatment services.

In semistructured interview sessions, 18 moderately retarded men undergoing deinstitutional training, were questioned to determine their understanding of pictures of homosexual embrace, masturbation, dating, marriage, intercourse, pregnancy, childbirth, drunkenness, and their knowledge of anatomical terminology. The frequencies of various response categories revealed a range of comprehension, the lowest answering only 10 percent correctly, the median consisting of 28 percent correct, and only 1 subject correctly answering as many as one-half of the items. Correct conceptual responses significantly correlated with WAIS Full Scale and Verbal IQs and were also significantly related to the Adaptive Behavior Scale domains of Language, Socialization, and Responsibility. Serious errors of fact and conceptual confusion, though most prevalent in responses by the low comprehenders, were found in at least some responses by all of the men.

Barriers to high blood pressure (BP) awareness and control are exacerbated by poor knowledge of the consequences and uncertainty regarding how to and who should direct care. We developed a social marketing hypertension awareness program to determine baseline awareness, knowledge, and treatment behavior, and then studied the impact of a targeted, media intervention among randomly surveyed adults at risk in a representative urban community compared to a control community immediately and 6 months after the intervention. The program consisted of three random-digit telephone surveys conducted in two mid-sized Ontario cities to determine high BP awareness, knowledge, and treatment behavior. Using baseline knowledge and attitudes toward high BP in both communities, a social marketing awareness strategy and mass media intervention campaign incorporating television, radio, print, direct to patient, and interactive techniques was developed and implemented in the test city only. Both test and control cities were resurveyed immediately after and at 6 months post-media intervention to detect change and decay. A sample of 6873 men and women more than 35 years old who were aware of their high BP demonstrated a high prevalence of high BP in the general population ( approximately 34% in both communities). At baseline this population had poor knowledge of their own BP numbers and poor understanding of the diseases related to high BP. Although few considered high BP a health concern, they had good understanding of lifestyle interventions for high BP prevention and control. The number of the respondents who claimed to have high BP increased immediately after intervention in the test city (38%; P < .02), whereas the number of respondents who were treated and uncontrolled decreased (P < .05) compared to control. There was a significant increase in patients' knowledge of consequences and in their perception that they were most responsible for high BP control in the test city (P < .005) compared to control. At 6 months, no further changes were observed in those claiming to have high BP in either city, whereas decay to baseline in those treated but not controlled and those claiming responsibility for their BP control was observed in the test city. No changes were observed in the control city accept for an increase from baseline to 6 months in the percentage claiming to be treated but uncontrolled. We were unable to determine whether the increase in number treated but uncontrolled was due to a higher treatment rate, similar treatment rate but more patients being uncontrolled, or a combination of these scenarios. High BP is very prevalent in adults and knowledge of lifestyle options for management is encouraging. In the short-term, although our media awareness program increased the number of respondents claiming to have high BP and patient self-efficacy for BP control, this was not maintained. We did not change knowledge of consequences or importantly, the health importance of BP control among those at risk. Hence, in addition to a mass media campaign, attention should be focused on dissemination of awareness knowledge information through medical professionals at the point of care.

To assess the knowledge of Abaye Deneba community members regarding intestinal parasites and prevalence of intestinal parasitic infections. Knowledge about intestinal parasites was assessed by administering a questionnaire to 345 randomly selected household heads. Parasitological stool examination of 491 randomly selected individuals was done using the formol ether concentration technique. Knowledge of the Abaye Deneba community about parasitic diseases such as schistosomiasis, amoebiasis, ascariasis and taeniasis was very low. However, 204 (59.3%) members correctly responded that the cause of giardiasis is related to contaminated water and 176 (51.2%) knew how to prevent it. In some cases, respondents did correctly identify causes, symptoms of intestinal parasite infection and ways to prevent it, but they did not accurately link it to the appropriate disease caused by the different intestinal parasite species. Among the 491 stool samples examined, 50.2% of study participants showed infection with at least one intestinal parasite. Schistosoma mansoni was the most prevalent (41.3%) followed by Trichuris trichiura(9.4%), Ascaris lumbricoides (8.4%), Taenia saginata (2.4%), Enterobius vermicularis (2.0%) and hookworm (0.4%). Prevalence of schistosomiasis was highest in men aged 15-24 years. Intestinal parasitic infection is highly prevalent in communities of the Abaye Deneba area. Nevertheless, the knowledge of the community members about the parasite is less. Implementation of preventive chemotherapy, supplemented with health education, provision and use of sanitary facilities would be recommended to reduce morbidity and control transmission of intestinal parasites in this area.

Army barracks in Nigeria have low contraceptive prevalence rates (CPRs) and many children per family. The aim of this interventional study, involving 963 married women, is to determine the impact of health education on family planning knowledge, attitudes, and practices among married barrack women. The intervention group attended a 50-minute health talk and demonstrations on family planning methods. In the intervention group, the mean knowledge score rose significantly, from 5.5 points to 7.8 points post-intervention (t = -16.7281, p = 0.0000, df = 460). In addition, the CPR increased significantly, from 11.8% at baseline to 22.4% post-intervention (McNemar's chi2 = 125.41, p = 0.0000). Such significant changes were not noted in the control group. We conclude that health education is an effective intervention for improving knowledge about and attitudes towards contraceptives and their use among married women in military barracks in Nigeria. Intense and sustained health education is therefore recommended in addressing the low CPR in Nigeria.

Tooth wear is an oral lesion with multifactorial causes. The prevalence is increasing with an increasing age. Knowledge of tooth wear is part of oral health and essential requirements are needed to modify health related behaviors. This study was aimed to determine the knowledge, attitude and practice of tooth wear and to compare with the socio-demographic factors. A cross-sectional study using a modified version of self-administered questionnaire was distributed among 390 adults (aged more than 18 years old) from three government institutions in Bertam, Penang. A total of 349 (89.5%) subjects had participated in this study with 55.3% were males and majority of the subjects were Malays. About 58.2% had low level of knowledge with mean score at 20.8. Meanwhile, 93.4% subjects had a positive attitude and 84.2% had poor level of practice on oral hygiene. The low mean score of knowledge among subjects was not necessary an indicator that attitude and practice were affected. However, identification of etiological factors emphasizes on educational approaches, and empowerment of patients and community towards awareness are the most important factors for preventive strategies.

Chronic pain is prevalent in the western world; however fear of pain often has a greater impact than the degree of initial injury. The aim of this study was to explore the relationship between knowledge of the neurophysiology of pain and fear avoidance in individuals diagnosed with chronic pain. Twenty-nine people with chronic musculoskeletal pain were recruited and completed questionnaires to determine their understanding of pain neurophysiology and the degree of their fear avoidance beliefs. There was an inverse relationship between knowledge of pain neurophysiology and the level of fear avoidance. Patients with higher pain knowledge reported less fear avoidance and lower perceived disability due to pain. There was no relationship with the educational level or compensable status for either variable. The findings suggest that fear avoidance is positively influenced by neurophysiology of pain education, so that a higher level of pain knowledge is associated with less activity-related fear. The clinical implication is that reducing fear avoidance/kinesiophobia using neurophysiology of pain education in people with chronic pain may provide an effective strategy to help manage fear avoidance and related disability in the chronic pain population in order to improve treatment outcomes.

To determine the prevalence of delayed discharges of elderly inpatients and associated costs. We searched Medline, Embase, Global Health, CAB Abstracts, Econlit, Web of Knowledge, EBSCO - CINAHL, The Cochrane Library, Health Management Information Consortium, and SCIE - Social Care Online for evidence published between 1990 and 2015 on number of days or proportion of delayed discharges for elderly inpatients in acute hospitals. Descriptive and regression analyses were conducted. Data on proportions of delayed discharges were pooled using a random effects logistic model and the association of relevant factors was assessed. Mean costs of delayed discharge were calculated in USD adjusted for Purchasing Power Parity (PPP). Of 64 studies included, 52 (81.3%) reported delayed discharges as proportions of total hospital stay and 9 (14.1%) estimated the respective costs for these delays. Proportions of delayed discharges varied widely, from 1.6% to 91.3% with a weighted mean of 22.8%. This variation was also seen in studies from the same country, for example, in the United Kingdom, they ranged between 1.6% and 60.0%. No factor was found to be significantly associated with delays. The mean costs of delayed discharge also varied widely (between 142 and 31,935 USD PPP adjusted), reflecting the variability in mean days of delay per patient. Delayed discharges occur in most countries and the associated costs are significant. However, the variability in prevalence of delayed discharges and available data on costs limit our knowledge of the full impact of delayed discharges. A standardization of methods is necessary to allow comparisons to be made, and additional studies are required-preferably by disease area-to determine the postdischarge needs of specific patient groups and the estimated costs of delays. © The Author 2017.

The aim of the study was to determine the prevalence of shisha smoking and associated factors among medical students in Malaysia. A cross-sectional study was conducted at the Management and Science University from December 2011 until March 2012. The questionnaire consisted of five sections including socio-demographic, social environment, knowledge about shisha, psychosocial factors, and personal shisha smoking behavior. Obtained data were analyzed using Statistical Package for the Social Sciences (SPSS 13). T-test was used to determine the relationships between shisha smoking and socio-demographic characteristic. A total number of 300 medical students participated in this study. Mean age was 22.5±2.5 years. The majority were female, Malay, single, from urban areas (67%, 54%, 97%, 73%; respectively). The prevalence of shisha smoking among medical students was found to be 20%. The study revealed that many students believed that shisha does not contains nicotine, carbon monoxide, does not lead to lung cancer, dental problems and does not lead to cardiovascular diseases (25%, 20.7%, 22.3%, 29%, 26.7%; respectively). Age and sex were found to be significantly associated with smoking shisha status among medical students (p=0.029, p<0.001; respectively). Furthermore, having parents, siblings and friends smokers of shisha were found to be significantly associated with shisha smoking status (p<0.001, p<0.001, p<0.001; respectively). Furthermore, family problems, problems with friends, financial problems and university life were found to significantly associated with shisha smoking status among medical students (p<0.001, p=0.002, p<0.001, p=0.002; respectively). There is a high prevalence of shisha smoking and a poor knowledge about its impact on health among medical students. More attention is needed to focus on medical education in this regard. The policies that are currently employed in order to reduce the cigarettes smoking should be applied to shisha smoking and shisha products.

To determine percentages of domestic cats and dogs vaccinated against rabies, identify barriers to vaccination, and assess knowledge about rabies in a semirural New Mexico community after a skunk rabies outbreak. Cross-sectional, door-to-door, bilingual, community-based participatory survey. 366 residential properties in Eddy County, NM. The New Mexico Department of Health and CDC administered surveys and analyzed data. Individuals at 247 of the 366 residential properties participated in the survey. One hundred eighty of the 247 (73%) households owned a dog (n = 292) or cat (163). Cats were more likely than dogs to not have an up-to-date rabies vaccination status (prevalence ratio, 3.2; 95% confidence interval, 2.3 to 4.4). Cost and time or scheduling were the most frequently identified barriers to vaccination. One hundred sixty (65%) respondents did not know livestock can transmit rabies, 78 (32%) did not know rabies is fatal, and 89 (36%) did not know a bat scratching a person can be an exposure. Only 187 (76%) respondents indicated they would contact animal control if they saw a sick skunk, and only 166 (67%) indicated they would contact animal control if bitten by a dog they did not own. Findings indicated that rabies vaccination prevalence among pet dogs and cats was low, despite the fact that the region had experienced a skunk rabies outbreak during the previous 2 years. In addition, substantial percentages of respondents did not have correct knowledge of rabies or rabies exposure.

Background In 2010, an estimated 141 new HIV infections occurred per day in Cameroon and reports suggest an upsurge of these rates by 2020 if current trends continue. Mother—to—child transmission (MTCT) of HIV is a major public health challenge, and maternal knowledge on HIV transmission during pregnancy and its prevention is important in curtailing paediatric HIV acquisition. Objectives We aimed at establishing the prevalence of maternal HIV infection as well as assessing knowledge on HIV, MTCT and prevention of MTCT (PMTCT) of HIV among pregnant women in a rural area of Cameroon. Methods This study was conducted in two phases: a 29 month retrospective analysis of 1866 deliveries within three rural health facilities in the Babessi sub—division, Northwest Cameroon and a 1 month prospective phase wherein 150 consenting pregnant women attending antenatal care (ANC) at the study centres were consecutively recruited. Results Overall, the prevalence of maternal HIV infection was 5.0% (100/2016). All (100%) of the interviewed pregnant women were aware of HIV infection and most (76.7%) had adequate knowledge on its routes of transmission. Meanwhile, only 79.3% (119/150) of them were aware of MTCT with slightly above a third (37.0%) having adequate knowledge on the periods of transmission. The proportions of women correctly stating: during pregnancy, during labour/delivery and during breastfeeding as possible periods of MTCT of HIV were 63.0%, 60.5% and 89.1% respectively. A majority (76.3%) of these women had inadequate knowledge on PMTCT of HIV. Conclusion The overall prevalence of maternal HIV warrants strengthening of current intervention strategies including scaling—up of PMTCT measures. Among others, intensification of HIV—related ANC services to improve the pregnant women’s awareness and knowledge on MTCT and its prevention are vital steps in curbing the growing burden of paediatric HIV.

Equestrian sport carries with it an implicit risk of injury. Despite the frequency of injuries in equestrian sports, there is no published study on injuries of equestrian athletes in Malaysia. The objective of this study was to determine the prevalence of injuries and its correlates among horseback riders. A web-based standardized questionnaire was used to collect data for this cross-sectional survey. Horseback riders aged 18 years and above were included in the study. Out of 169 participants, 93 were females and 76 were males. The correlation of injuries to gender, age, level of experience, exercise habits, use of safety measures, and type of equestrian sport were determined. Chi-square test was performed to test for statistical significance. The prevalence was high with 85.8% of the participants reporting symptoms and characteristics of injuries in the past 12 months. The most frequently perceived symptoms reported were in the upper extremities (43.4%) followed by lower extremities (40.7%), head injury (8.3%) and injuries of upper and lower back (3.4%). There was a higher prevalence of injury among female participants (55.03%) than males (42.60%). A significant correlation was found between gender and prevalence of injuries. About 70% of the riders sustained soft tissue injuries. Fifty-five percent of the injured were involved in recreational riding. The most common mechanism of injury was a fall from a horse. Sixty percent of the injured riders did not seek medical attention after being injured, and physiotherapy consultation was even lower with 10.3%. The high prevalence of injuries and low rate of medical consultation emphasize the need for education programs on safety in Malaysia. Sessions should be held to improve coaching for riders and instructors, and their knowledge of the nature of the horse, mechanisms of injuries, horse handling, and riding skills to help them host safe equestrian activities.

Orthorexia nervosa (ON) describes the constant pathological preoccupation with "healthy" nutrition. The current results regarding the prevalence of ON differ widely possibly because of invalid measurement tools. This study aimed to investigate ON prevalence in a sample of German students and to examine age, gender, semester, and nutritional knowledge as potential predictors of ON by comparing nutrition science (NS) with economics (ES) students. A total of 446 university students participated in the survey (NS 188, ES 268). ON was determined using the 21-item-DOS, which is a well-constructed, validated, and reliability-tested questionnaire. Age, gender, and semester were also assessed. Of the total sample, 3.3 % were classified as having ON and 9.0 % were at risk of developing ON. Older students scored significantly higher on the subscale "avoidance of additives" compared with younger students and students of lower semester suffered significantly more often from ON than students of higher semester. In addition, comparing field of study showed no significant difference in the prevalence of ON or the risk of developing ON between female NS and ES students. However, mean values for the three DOS subscales were higher among female NS students, albeit far below values indicating pathological behavior. The prevalence of ON appears to be low in this sample of German university students. Female NS students do not seem to have higher prevalence of ON or risk of developing ON.

Objective To determine the degree of knowledge that cardiologists from São Paulo, Brazil, have regarding a low-prevalent entity associated with a high rate of sudden death—Brugada syndrome. Methods Two hundred forty-four cardiologists were interviewed by an instrument divided in two parts: in the first, we recorded gender, age, and data related to academic profile. The second—answered only by the professionals that manifested having some degree of knowledge on the syndrome—had 28 questions that evaluated their knowledge. The answers were spontaneous and they did not have a chance to consult. We used uni- and multivariate analysis on the average percentage of right and wrong answers, and the influence of the academic profile. Results The predominant gender was the male gender (61.1%), the average age was 44.32 ± 10.83 years, 40% with more than 20 years after obtaining their degree, 44% were educated in public institutions, 69% had a residency in cardiology, 20% had overseas practice, 12% had postdegree, 41% were linked to an educational institution, 24% with publication(s) in an indexed journal, 17.2% were authors of chapters in books, 2.5% had edited books, and 10% were linked to the Brazilian Society of Cardiac Arrhythmias. The average percentage of right answers was 45.7%. Conclusion The sample studied revealed a little knowledge on the entity. A residency in cardiology was the factor of greater significance in the percentage of right answers. Other significant factors were the link of the interviewed person to an educational institution, or the Brazilian Society of Cardiac Arrhythmias, and having a specialist degree. PMID:18973492

The aims of this study are to assess prevalence of awareness of sun protection campaigns among parents in Bavaria, Germany, to analyse the impact of sociodemographic factors on campaign knowledge and the association between parental campaign knowledge and sun protection behaviour in their children. A cross-sectional survey was undertaken in 2010-2011 in Bavaria, Germany, with parents of 4,579 children aged 5-6 years (response rate 61%). Prevalence of knowledge of sun protection campaigns is 13% among parents in Germany and independent of sociodemographic factors. Ignorance of sun protection campaigns is associated with inadequate sun protection behaviour in children independent of sociodemographic and exposure characteristics. Awareness of sun protection campaigns is low among parents. Knowledge of adequate sun protection behaviour should be further increased at the population level in Germany independently of sociodemographic status. © Georg Thieme Verlag KG Stuttgart · New York.

Cervical cancer is the third most common cancer in women in peninsular Malaysia and very prevalent worldwide. HPV vaccination and routine Pap smear testing are the best preventive measures. The objective of this study was to determine the knowledge level of secondary school students from Sarawak, East Malaysia regarding cervical cancer and its prevention. Multistage random sampling with various methods in each step was employed to select the sample of 76 students. Results showed that 61.8% had poor knowledge level of cervical cancer and its prevention. There were 60.5% of students who were aware of cervical cancer with Chinese and form four students showing significantly the highest awareness (p<0.05). The main source of cervical cancer information was from their parents (25.9%). HPV vaccination acceptance among students was 22.3% and an association was found between knowledge of cervical cancer with race and HPV vaccination acceptance (p<0.05). In conclusion, the students had poor knowledge level of cervical cancer, its prevention and HPV vaccination acceptance. More efforts should be made to improve cervical cancer knowledge and awareness of the public especially secondary school students in Sarawak. This in turn will enhance the practice of prevention against cervical cancer among students.

Aim . To assess the prevalence of dental caries, oral hygiene knowledge, status, and practices among visually impaired individuals in Chennai, Tamil Nadu. Materials and Methods . A cross-sectional study was conducted among 404 visually impaired individuals in Chennai city, Tamil Nadu. Four schools were randomly selected for conducting the study. The oral hygiene status, prevalence of caries, and knowledge and attitude towards oral care among visually impaired individuals were collected and analysed. Results . In the present study, whilst 42% of individuals had fair oral hygiene status, 33% had good hygiene followed by 25% having poor oral hygiene. The overall mean number of DMFT was estimated to be 4.5 ± 2.7. The mean number of decayed teeth was 3.1 ± 2.2, mean number of missing teeth was 0.8 ± 1.4, and mean number of filled teeth was 0.5 ± 1.3. Conclusion . Whilst oral hygiene status was found to be relatively fair, there was a high rate of dental caries among the sample population. This shows that there is lack of knowledge regarding oral health maintenance. Therefore, early identification of caries coupled with effective oral health promotion programs providing practical knowledge to visually impaired students would prove beneficial.

To analyse knowledge, attitudes and sexual practices on HIV/AIDS, and estimate HIV prevalence among residents of Sucre (Bolivia). Population-based survey of residents aged 15-49 randomly selected during 2008/2009. Blood samples were collected on Whatman-filter paper and tested with enzyme-linked immunosorbent assay. Knowledge on HIV/AIDS, sexual risk practices and discriminatory attitudes against people living with HIV/AIDS (PLWHA) were modelled with multiple logistic regression. Of 1499 subjects, 59% were women. All subjects were HIV-negative. Inadequate knowledge of HIV/AIDS transmission and prevention was observed in 67% and risk factors varied by gender (interaction p-value<0.05). Discriminatory attitudes were displayed by 85% subjects; associated factors were: rural residence, low educational level and low income. Unsafe sex was reported by 10%; risk factors varied by residence area (interaction p-value<0.05). In urban areas, risk factors were male sex, younger age and being in common-law union. Prevalence of HIV infection is very low and unsafe sex is relatively uncommon. Inadequate knowledge on HIV/AIDS and discriminatory attitudes towards PLWHA are extremely high and are associated to gender, ethnic and economic inequalities. Copyright © 2015 Elsevier Editora Ltda.

There is a dearth of published literature that demonstrates the impact and effectiveness of school-based oral health education (OHE) program in Bangladesh and it is one of the most neglected activities in the field of public health. Keeping this in mind, the objectives of this study were to assess the effectiveness of OHE program in: 1) increasing oral health knowledge, attitude, and practices and 2) decreasing the prevalence of untreated dental caries among 6-8 grade school students in Bangladesh. This intervention study was conducted in Araihazar Thana, Narayanganj district, Bangladesh during April 2012 to March 2013. The total participants were 944 students from three local schools. At baseline, students were assessed for oral health knowledge, attitude and practices using a self-administered structured questionnaire and untreated dental caries was assessed using clinical examination. Follow up study was done after 6 months from baseline. McNemar's chi-square analysis was used to evaluate the impact of OHE program on four recurrent themes of oral health between the baseline and follow-up. Multiple logistic regression analyses were used to determine the impact of the intervention group on our outcome variables. Significant improvement was observed regarding school aged adolescents' self-reported higher knowledge, attitude and practices scores (p < 0.001) at follow-up compared with baseline. The prevalence of untreated dental caries of the study population after the OHE program was significantly (p < 0.01) reduced to 42.5 %. Multiple logistic regression analyses showed that the OHE intervention remained a significant predictor in reducing the risk of untreated dental caries (adjusted odds ratio [AOR] =0.51; 95 % confidence interval [CI] = 0.37, 0.81). In the follow-up period participants were 2.21 times (95 % CI = 1.87, 3.45) more likely to have higher level of knowledge regarding oral health compared to baseline. Compared with baseline participants in the follow-up were 1.89 times (95 % CI = 1.44-2.87) more likely to have higher attitude towards oral health. In addition, OHE intervention was found to be significantly associated with higher level of practices toward oral health (AOR = 1.64; 95 % CI = 1.12, 3.38). This study indicated that OHE intervention was effective in increasing i) knowledge, ii) attitude, and iii) practices towards oral health; it also significantly reduced the prevalence of untreated dental caries among school aged adolescents from grade 6-8 in a deprived rural area of Bangladesh.

Iron deficiency anemia (IDA) affects 70% of under-5 children in India. The primary prevention strategy is regular iron supplementation. Little is known about what helps families adhere to daily iron supplementation. Our study explored the knowledge, attitudes, and practices of mothers and village health workers (VHWs) involved in a community health program in one hill district of Tamil Nadu. We conducted 30 semistructured interviews and 3 group discussions involving mothers, VHWs, and community stakeholders. Knowledge of IDA was widespread, yet no children were receiving the iron supplementation as recommended. The main determinants to adherence included the perception of its need, the ease of access, and the activity of VHWs. Preventive care requiring daily supplements is challenging. Our study suggests that increasing community awareness of mild anemia, simplifying dosage instructions, and further strengthening the supportive environment for VHWs would help in reducing the prevalence of IDA. © 2013 APJPH.

To determine the prevalence and type of human papilloma virus deoxyribonucleic acid (DNA) in cases of laryngeal squamous cell carcinoma. We analysed the prevalence of human papilloma virus infection in archived paraffin block specimens taken from 99 cases of laryngeal squamous cell carcinoma between 1990 and 2005, using polymerase chain reaction techniques. Biopsy specimens from five proven verrucous skin lesions were used as positive controls, and peripheral blood samples from five healthy volunteers were used as negative controls. Four test samples were found to have inadequate deoxyribonucleic acid purity and were therefore excluded from the study. Human papilloma virus deoxyribonucleic acid was detected in seven of 95 cases of laryngeal squamous cell carcinoma (7.36 per cent). Human papilloma virus genotyping revealed double human papilloma virus infection in three cases and single human papilloma virus infection in the remaining four cases. The human papilloma virus genotypes detected were 6, 11 and 16 (the latter detected in only one case). In our series, a very low human papilloma virus prevalence was found among laryngeal squamous cell carcinoma cases. The human papilloma virus genotypes detected were mostly 6 and/or 11, and 16 in only one case. To the best of our knowledge, this is the first report of human papilloma virus prevalence in laryngeal squamous cell carcinoma, based on polymerase chain reaction genotyping in a Turkish population.

People with disabilities are known to experience disparities in behavioral health risk factors including smoking and obesity. What is unknown is how disability, race/ethnicity, and socioeconomic status combine to affect prevalence of these health behaviors. We assessed the association between race/ethnicity, socioeconomic factors (income and education), and disability on two behavioral health risk factors. Data from the 2007-2010 Behavioral Risk Factor Surveillance System were used to determine prevalence of cigarette smoking and obesity by disability status, further stratified by race and ethnicity as well as income and education. Logistic regression was used to determine associations of income and education with the two behavioral health risk factors, stratified by race and ethnicity. Prevalence of disability by race and ethnicity ranged from 10.1 % of Asian adults to 31.0 % of American Indian/Alaska Native (AIAN) adults. Smoking prevalence increased with decreasing levels of income and education for most racial and ethnic groups, with over half of white (52.4 %) and AIAN adults (59.3 %) with less than a high school education reporting current smoking. Education was inversely associated with obesity among white, black, and Hispanic adults with a disability. Smoking and obesity varied by race and ethnicity and socioeconomic factors (income and education) among people with disabilities. Our findings suggest that disparities experienced by adults with disabilities may be compounded by disparities associated with race, ethnicity, and socioeconomic factors. This knowledge may help programs in formulating health promotion strategies targeting people at increased risk for smoking and obesity, inclusive of those with disabilities.

The prevalence of cervicovaginal infections during pregnancy has been associated with adverse perinatal outcomes however, the actual approach used for diagnosis is not effective. The aim of this study was to compare the diagnosis of vaginal infections in pregnant women using clinical, molecular diagnostic and traditional microbiological culture in a pilot study, to determine the prevalence and association with the development of preterm labor. We performed a nested cross-sectional study composed by 54 women in a cohort of pregnant women in Mexico City. Cervicovaginal infections were evaluated by clinical methods, microbiology culture and a commercially available molecular biology test. Prevalence of cervicovaginal infections during pregnancy was estimated between 28% and 50% according to methodologies. Considering the clinical diagnosis of preterm labor as the gold standard, all diagnostic tests were poor as predictors of preterm labor. Traditional approaches to establish the significance of cervicovaginal infection in pregnancy are exhausted, so be sought new ways to understand this complex relationship. Meanwhile it is recommended to continue to use traditional methods to identify infections during pregnancy in both knowledge of new methods aimed at understanding these relationships are sophisticated.

It is widely advocated that integrated strategies for the control of neglected tropical diseases (NTDs) are cost-effective in comparison to vertical disease-specific programmes. A prerequisite for implementation of control interventions is the availability of baseline data of prevalence, including the population at risk and disease overlap. Despite extensive literature on the distribution of schistosomiasis on the mainland in Uganda, there has been a knowledge gap for the prevalence of co-infections with malaria, particularly for island communities in Lake Victoria. In this study, nine lakeshore and island districts were surveyed for the prevalence of NTDs and malaria, as well as educational and health infrastructure. A total of 203 communities were surveyed, including over 5000 school-age children. Varying levels of existing health infrastructure were observed between districts, with only Jinja District regularly treating people for NTDs. Community medicine distributors (CMD) were identified and trained in drug delivery to strengthen capacity. Prevalence levels of intestinal schistosomiasis and soil-transmitted helminthiasis were assessed via Kato-Katz thick smears of stool and malaria prevalence determined by microscopy of fingerprick blood samples. Prevalence levels were 40.8%, 26.04% and 46.4%, respectively, while the prevalence of co-infection by Schistosoma mansoni and Plasmodium spp. was 23.5%. Socio-economic status was strongly associated as a risk factor for positive infection status with one or more of these diseases. These results emphasise the challenges of providing wide-scale coverage of health infrastructure and drug distribution in remote lakeshore communities. The data further indicate that co-infections with malaria and NTDs are common, implying that integrated interventions for NTDs and malaria are likely to maximize cost-effectiveness and sustainability of disease control efforts.

Background Obesity is a major risk factor for emerging non-communicable diseases (NCDS) in middle income countries including South Africa (SA). Understanding the multiple and complex determinants of obesity and their true population attributable impact is critical for informing and developing effective prevention efforts using scientific based evidence. This study identified contextualised high impact factors associated with obesity in South Africa. Methods Analysis of three national cross sectional (repeated panel) surveys, using a multilevel logistic regression and population attributable fraction estimation allowed for identification of contextualised high impact factors associated with obesity (BMI>30 kg/m2) among adults (15years+). Results Obesity prevalence increased significantly from 23.5% in 2008 to 27.2% in 2012, with a significantly (p-value<0.001) higher prevalence among females (37.9% in 2012) compared to males (13.3% in 2012). Living in formal urban areas, white ethnicity, being married, not exercising and/or in higher socio-economic category were significantly associated with male obesity. Females living in formal or informal urban areas, higher crime areas, African/White ethnicity, married, not exercising, in a higher socio-economic category and/or living in households with proportionate higher spending on food (and unhealthy food options) were significantly more likely to be obese. The identified determinants appeared to account for 75% and 43% of male and female obesity respectively. White males had the highest relative gain in obesity from 2008 to 2012. Conclusions The rising prevalence of obesity in South Africa is significant and over the past 5 years the rising prevalence of Type-2 diabetes has mirrored this pattern, especially among females. Targeting young adolescent girls should be a priority. Addressing determinants of obesity will involve a multifaceted strategy and requires at individual and population levels. With rising costs in the private and public sector to combat obesity related NCDS, this analysis can inform culturally sensitive mass communications and wellness campaigns. Knowledge of social determinants is critical to develop “best buys”. PMID:26061419

Noise induced hearing loss (NIHL) is an irreversible sensorineural hearing loss associated with exposure to high levels of excessive noise. Prevention measures are not well established in developing countries. This comparative cross sectional study aims to determine the prevalence of hearing loss in both a group of high risk workers and a control group and to assess their knowledge of the effects of noise on hearing health. A total of 101 market mill workers and 103 controls employed within markets in the city of Accra, Ghana, were evaluated using a structured questionnaire and pure tone audiometry. The questionnaire assessed factors including self-reported hearing loss, tinnitus, knowledge on the effects of noise on hearing health and the use of hearing protective devices. Pure tone audiometric testing was conducted for both mill workers and controls. Noise levels at the work premises of the mill workers and controls were measured. Symptoms of hearing loss were reported by 24 (23.76%) and 8 (7.7%) mill workers and controls respectively. Fifty-five (54.5%) and fifty-four (52.37%) mill workers and controls exhibited knowledge of the effects of noise on hearing health. Five (5.0%) mill workers used hearing protective devices. There was significant sensorineural hearing loss and the presence of a 4 kHz audiometric notch among mill workers when compared with controls for the mean thresholds of 2 kHz, 3 kHz and 4 kHz (P = 0. 001). The prevalence of hearing loss in the better hearing ears of the mill workers and controls was 24.8% and 4.8% respectively (P < 0.5). The prevalence of hearing loss, which may be characteristic of NIHL in the better hearing ears of the mill workers and controls was 24.8% and 4.8% respectively. The majority of mill workers did not use hearing protection.

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters.

This study aimed to determine the prevalence and social determinants of waterpipe (WP) smoking among secondary school students in Al-Hassa, Saudi Arabia and to assess their health related knowledge and attitudes toward WP. A cross-sectional study was conducted with 1,652 Saudi secondary school students of both genders aged between 15-19 years selected by multistage sampling method. A self-administered anonymous Arabic version of Global Youth Tobacco Survey modified with items dedicated to WP smoking and to assess perception of health related hazards and attitudes towards WP was employed for data collection. Prevalence of current smokers 'all forms' was 30.3% among males (C.I= 27.5- 33.2%) and 8.5% in females (C.I= 6.6-10.9%). WP was used by 53.9% of the current tobacco users, significantly higher among older age students. Of the regular WP smokers, 20.7% smoked WP on daily basis, 23.8% weekly, 64.2% stated using flavored " Muassel " tobacco. Primary motives for WP smoking were outings with friends, company, boredom and wasting time. Of the total, 49.7% of students stated that WP smoking is less harmful than cigarettes, 60.5% believed that harmful substances were purified through water filtration, with non-addictive properties in 67.8%. Knowledge about health hazards of WP smoking was low, irrespective of student's smoking status. WP smoking is more socially acceptable than cigarettes (52.1%), represents a good opportunity for gathering of friends and family (33.8%), and smoking of WP can relieve stress and tensions (37.8%). Hierarchical regression analysis showed that socializing motives, cigarette smoking, smoking among close family and friends, male gender and increasing age were positive predictors for WP smoking. Social acceptability, poor knowledge of WP health related hazards and certain socio demographics are favoring the increasing current trend of WP use among adolescents in Al Hassa, Saudi Arabia.

The high prevalence of childhood obesity is a major concern in developed and developing countries. An increase in fruit and vegetable (F&V) intake is perceived as one of the numerous strategies to prevent and reduce the risk of adiposity. The purpose of this study was to investigate the relevance of personal and social determinants in explaining children's F&V intake. Written questionnaire data were collected from 702 parent-child pairs that included 3rd and 4th graders (aged 7 to 10) and their parents. Children's F&V intake was recorded over three food records. Hierarchical linear regression models were applied to assess the impact of personal and social determinants on children's F&V intake. Regression models focusing on personal and social determinants revealed that the most promising personal determinants pertained to the knowledge of different types of F&V and preferences for F&V. Moreover, an exclusive focus on social determinants indicated that parental modeling and peer influence had significant and positive relationships with children's F&V intake, whereas verbal directives to eat F&V exhibited a significant and negative relationship. In combination, the following four personal and social determinants were demonstrated to be significant: knowledge of different types of F&V, preferences for F&V and parental modeling, all of which had positive relationships, and verbal directives to eat F&V, which had a negative impact. The results identify important associative determinants of children's F&V intake. These are in part personal and in part social and are shown by our analysis to be of equal and perhaps mutual importance. Therefore, we suggest that interventions aimed at improving children's F&V intake should address children's preferences for F&V, impart knowledge concerning the variety of F&V and encourage parents to act as role models.

Nowadays, there is a trend of HIV prevalence transmitting from high-risk group to average-risk group in China. Rural China is the weak link of HIV prevention, and rural areas of Henan province which is one of the most high-risk regions in China have more than 60% of the AIDS patients in the province. Thus, improving the HIV awareness and implementing health education become the top-priority of HIV/AIDS control and prevention. A multistage sampling was designed to draw 1129 people living with HIV/AIDS (PLWHAs) and 1168 non-PLWHAs in 4 prevalence counties of Henan province. A health promoting and social-psychological support model was constructed to improve the health knowledge of participants. Chi-square tests and unconditional logistic regression were performed to determine the intervention effect and influencing factors. All groups had misunderstandings towards the basic medical knowledge and the AIDS transmission mode. Before the intervention, 59.3% of the HIV/AIDS patients and 74.6% of the healthy people had negative attitudes towards the disease. There was statistically significant difference in the improvement of knowledge, attitude and action with regards to HIV prevention before and after intervention (P<0.05). PLWHAs who were males (OR=1.731) and had higher education level (OR=1.910) were found to have better HIV/AIDS health knowledge, whereas older PLWHAs (OR=0.961) were less likely to have better HIV/AIDS health knowledge. However, the intervention effect was associated with the expertise of doctors and supervisors, the content and methods of education, and participants' education level. It was concluded that health education of HIV/AIDS which positively influences the awareness and attitude of HIV prevention is popular in rural areas, therefore, a systematic and long-term program of HIV control and prevention is urgently needed in rural areas.

Objective To determine physicians’ knowledge, awareness and preferences regarding the care of familial hypercholesterolaemia (FH) in the Asia-Pacific region. Setting A formal questionnaire was anonymously completed by physicians from different countries/regions in the Asia-Pacific. The survey sought responses relating to general familiarity, awareness of management guidelines, identification (clinical characteristics and lipid profile), prevalence and inheritance, extent of elevation in risk of cardiovascular disease (CVD) and practice on screening and treatment. Participants Practising community physicians from Australia, Japan, Malaysia, South Korea, Philippines, Hong Kong, China, Vietnam and Taiwan were recruited to complete the questionnaire, with the UK as the international benchmark. Primary outcome An assessment and comparison of the knowledge, awareness and preferences of FH among physicians in 10 different countries/regions. Results 1078 physicians completed the questionnaire from the Asia-Pacific region; only 34% considered themselves to be familiar with FH. 72% correctly described FH and 65% identified the typical lipid profile, with a higher proportion of physicians from Japan and China selecting the correct FH definition and lipid profile compared with those from Vietnam and Philippines. However, less than half of the physician were aware of national or international management guidelines; this was significantly worse than physicians from the UK (35% vs 61%, p<0.001). Knowledge of prevalence (24%), inheritability (41%) and CVD risk (9%) of FH were also suboptimal. The majority of the physicians considered laboratory interpretative commenting as being useful (81%) and statin therapy as an appropriate cholesterol-lowering therapy (89%) for FH management. Conclusions The study identified important gaps, which are readily addressable, in the awareness and knowledge of FH among physicians in the region. Implementation of country-specific guidelines and extensive work in FH education and awareness programmes are imperative to improve the care of FH in the region. PMID:29074516

The aim of this study was to identify determinants of occupational sunburn in agricultural workers and assess their occupational and recreational sun protection habits. Specific surveys of agricultural workers in Switzerland and France were conducted (N = 1538). Multivariate logistic regressions identified occupational sunburn determinants. Occupational and recreational sun protection habits were estimated and correlated. One-year occupational and recreational sunburn prevalences were 19.8% and 11.5%, respectively. Occupational sunburn increased with having a recent recreational sunburn, highly sensitive skin, young age, high perceived skin cancer risk, using sunscreen, and not wearing a hat. Correlation between protection habits during work and leisure was substantial (rs 0.5 to 0.7). Skin health knowledge was high and pro-tanning attitude moderate. Potentially modifiable sunburn determinants and suboptimal recreational and occupational sun protection practices were identified in agricultural workers. Refining and tailoring sun protection messages targeting the agricultural sector are needed.

This study compared mental health and physical health literacy using five health problems from each area. The aim was to determine whether the same group had better physical than mental health literacy Method: A sample of 263 participants completed an online questionnaire requiring them to name a problem/illness described in 10 vignettes and suggest treatment options. Five vignettes described mental health problems (anxiety, bipolar-disorder, depression, OCPD and schizophrenia) and five physical problems (angina, COPD, diabetes, a heart attack, and sinusitis). Participants were also asked to rate their sympathy and estimates of prevalence for each disorder. Recognition of the mental health disorders was superior compared recognition of the physical disorders. Analysis of treatment beliefs, sympathy and prevalence ratings also showed significant differences between disorders. Results highlight the importance of education and the lack of public knowledge regarding major physical health conditions.

Female sex workers (FSWs) are at heightened risk of HIV infection. This research aims to determine the prevalence of HIV and relevant risk factors and related behavior among FSWs in Ba Ria - Vung Tau, a southeast province of Vietnam. 420 FSWs were interviewed using a structured questionnaire and biological samples tested for HIV. 2.6 % were found to be HIV positive. HIV infection was significantly higher in FSWs who had low income (≤AUD 200 per month), have had anal sex, have had sex with injecting drug users, and had a low level of HIV/AIDS-related knowledge. Improved employment opportunities and income are important to reduce the pressure for young women to engage in sex work for income purposes, but in public health terms, existing HIV treatment, prevention and intervention programs needs better targeting and improvements to reduce the risk of HIV infection.

Previous studies in the world reported inconsistent results about the relationship of medical professional education with medical students' smoking behaviors, and no similar research had been published in China. This paper aims to explore whether the differences of smoking-related knowledge, attitudes, and behaviors existed between medical and non-medical undergraduate students. Eight thousand one hundred thirty-eight undergraduate students sampled from a university in Guangzhou were investigated with a self-administered structured questionnaire about their smoking-related knowledge, attitude and behaviors, and other relevant factors. General linear model and multinomial logistic regression were conducted to test the differences in smoking-related knowledge, attitude, and behaviors between medical and non-medical students while controlling for potential confounding variables. There was no difference in smoking-related knowledge scores between medical and non-medical freshmen, but medical sophomores and juniors had higher scores of smoking-related knowledge than their non-medical counterparts. The medical sophomores had higher mean score of attitudes towards smoking than non-medical ones. Before entering university, the difference in the prevalence of experimental and regular smoking between medical and non-medical college students was not significant. After entering university, in contrast, the overall prevalence of regular smoking was significantly higher among male non-medical college students than among male medical students. Stratified by current academic year, this difference was significant only among male sophomores. Medical students have higher smoking-related knowledge, stronger anti-smoking attitude, and lower prevalence of regular smoking than non-medical college students of similar age, which may be associated with medical professional education.

This multicentre study aimed to assess compliance of the reporting environment with best ergonomic practice and to determine the prevalence of musculoskeletal symptoms related to working as a radiologist. All 148 radiology trainees and consultants in 10 hospitals across the region were invited to complete a musculoskeletal symptoms and reporting ergonomics questionnaire. Best ergonomic reporting practice was defined, following literature review, as being able to alter the following: monitor, desk, chair and armrest height, chair back support, ambient light, and temperature. The frequency that these facilities were available and how often they were used was determined. One hundred and twenty-three out of 148 (83%) radiologists responded, and 38% reported radiology-associated occupational injury. Lower back discomfort was the commonest radiology associated musculoskeletal symptom (41%). Only 13% of those with occupational injury sought the advice of occupational health. No reporting environments conformed completely to best ergonomic practice. Where certain facilities were available, less than a third of radiologists made personal ergonomic adjustments prior to starting a reporting session. Radiologists who had good self-assessed knowledge of best ergonomic practice had significantly less back discomfort than those with poor self-assessed knowledge (P < 0.005). We demonstrated high prevalence of musculoskeletal symptoms amongst radiologists. Poor compliance of the reporting environment with best ergonomic practice, in combination with our other findings of a low level of ergonomic awareness, low rates of making ergonomic adjustments and seeking appropriate help, may be implicated. We hope this study raises awareness of this issue and helps prevent long-term occupational injury amongst radiologists from poor ergonomic practice.

Haemoproteus spp. are common blood parasites of pigeons. They have been reported in pigeons in many regions worldwide, including Turkey. Pigeon breeding is a popular hobby in Kirikkale province, and there is no information about the prevalence of Haemoproteus spp. The present study aimed to determine the prevalence of Haemoproteus spp. in tumbler pigeons in Kirikkale province (Kırıkkale and Yahsihan district). Blood samples were taken from the wing vein of pigeons (n: 173) through microcapillary (with/heparin) tubes between February and March 2016. Blood smears were stained with 5% Giemsa solution. Ectoparasites of the pigeons were collected in separate sealed boxes. Epidemiological data of the sampled pigeons (age and sex) were obtained from the breeders. In total, 23 (%13.2) of 173 pigeons were infected with Haemoproteus spp. Parasite was detected in 73.9% of pigeons over 1 year old and 26.1% of pigeon under 1 year age. Haemoproteus spp. was observed in 56.2% of females (13/23) and 43.4% of males (10/23), Sex-related differences were not observed (p = 0.821). Ectoparasites of the pigeons were identified as Columbicola spp. To the best of our knowledge, this is the first study in Kirikkale province that reported the prevalence of Haemoproteus spp. in pigeons.

Objectives. We monitored the prevalence and patterns of use of the array of tobacco products available to young adults, who are at risk for initiation and progression to established tobacco use. Methods. We used data from waves 1 to 3 of GfK’s KnowledgePanel (2011–2012), a nationally representative cohort of young adults aged 18 to 34 years (n = 2144). We examined prevalence and patterns of tobacco product use over time, associated demographics, and state-level tobacco policy. We used multivariable logistic regression to determine predictors of initiation of cigarettes as well as noncombustible and other combustible products. Results. The prevalence of ever tobacco use rose from 57.28% at wave 1 to 67.43% at wave 3. Use of multiple products was the most common pattern (66.39% of tobacco users by wave 3). Predictors of initiation differed by product type and included age, race/ethnicity, policy, and use of other tobacco products. Conclusions. Tobacco use is high among young adults and many are using multiple products. Efforts to implement policy and educate young adults about the risks associated with new and emerging products are critical to prevent increased initiation of tobacco use. PMID:24922152

With the urbanisation of the population in developing countries and the process of globalisation, Chagas has become an emerging disease in the urban areas of endemic and non-endemic countries. In 2006, it was estimated that the prevalence of Chagas disease among the general Bolivian population was 6.8%. The aim of the present study was to determine the prevalence of Trypanosoma cruzi infection among Bolivian immigrants living in São Paulo, Brazil. This study had a sample of 633 volunteers who were randomly selected from the clientele of primary care units located in the central districts of São Paulo, Brazil. Infection was detected by two different ELISA assays with epimastigote antigens, followed by an immunoblot with trypomastigote antigens as a confirmatory test. The prevalence of the infection was 4.4%. Risk factors independently associated with the infection were: a history of rural jobs in Bolivia, knowledge of the vector involved in transmission, and having relatives with Chagas disease. Brazil has successfully eliminated household vector transmission of T. cruzi, as well as its transmission by blood transfusion. The arrival of infected immigrants represents an additional challenge to primary care clinics to manage chronic Chagas disease, its vertical transmission, and the blood derivatives and organ transplant programs.

Background Dentists may be the first health care professionals to treat patients who have experienced Oro-facial trauma resulting from Domestic violence (DV). Hence, as a national health concern, it challenges the social responsibility of a dentist in bringing down its prevalence. Objective To assess the knowledge of Domestic violence among dentists of Karnataka. Materials and Methods A cross-sectional questionnaire survey was conducted among dentists of Karnataka to know their knowledge, its relation to dentistry and measures they practice to bring down the prevalence of DV victims. Results Overall knowledge about DV was very less among the dentists & out of 64% who said the dentist has a role in bringing down the prevalence, 28% reported the need for training. Conclusion Based on analysis of the data, dentists were interested and would benefit from additional education opportunities concerning recognizing, referring and managing patients who may be the victim of domestic violence in order to enhance their role.

The purpose of this study was to describe the overall prevalence of migraines within National Collegiate Athletic Association Division I men's and women's basketball players. In addition, the prevalence of migraines was determined across gender and ethnic groups for the same sample. Although numerous studies have assessed the prevalence of migraines within the general population, college students, professional groups, industrial/work place settings, and overseas populations, little has been done with athletes. To the best of our knowledge, no study of the incidence of migraines in athletes has been previously conducted. It has also been reported that migraines cause depression, insomnia, fatigue, anorexia, nausea, and vomiting, all of which might hinder athletic performance. Sports medicine clinicians and researchers also agree that migraines in athletes are probably underreported and often misdiagnosed. Seven hundred ninety-one Division I men and women basketball players representing 51 colleges and universities were mailed a previously validated survey asking questions about headaches. All surveys were analyzed with a validated diagnostic algorithm consistent with the International Headaches Society's (IHS) criteria for headache diagnosis. Descriptive statistics were used to report the prevalence rate for gender and ethnic groups, as well as the entire sample. Chi-square tests were performed (P = 0.05) to determine if there were any differences in the prevalence of migraines among gender and ethnic groups. Results showed that 2.9% (n = 23 of 791) of the total sample was classified as having migraines meeting IHS guidelines. In addition, 0.9% (n = 3 of 332) of men and 4.4% (n = 20 of 459) of women were classified as having migraines meeting IHS guidelines. Additionally, results showed that women reported migraines (chi2 = 8.140, P = 0.004) more often than men. When comparing the prevalence rates of migraines between ethnic groups, results showed that Caucasians had a rate of 3.3% (n = 14 of 429), whereas African Americans had a rate of 3.1% (n = 9 of 287). There was no significant difference found between ethnic groups in migraine prevalence (chi2 = 2.491, P = 0.2888). In conclusion, it was found that the prevalence of migraines in National Collegiate Athletic Association Division I men's and women's basketball players was generally less than in the general population, that women showed an increased prevalence of migraines when compared with men, and that Caucasians and African Americans did not differ in prevalence of migraines.

The aim of this study was to determine the dentists' opinions on causes for high prevalence of dental caries in the country and to assess their level of knowledge about preventive dental care. A questionnaire based national crosssectional survey among 500 dentists was conducted under the auspices of Directorate of Dentistry, Ministry of Health. The data was analyzed using SPSS software version 11.0 and descriptive statistics were obtained. The response rate was 87.8% (n = 439). 83% of dentists identified poor oral hygiene as the major reason for high prevalence of caries, only 39% of patients reportedly brushed teeth at least once a day, oral prophylaxis (83%) is the most common preventive practice followed, social factors (62.5%) are the most challenging barriers in preventive dental programs, 71.3% always give chair side dental health education, school based programs (66.6%) are most effective tools for dental health education. Majority of dentists in Saudi Arabia are adequately informed and motivated toward preventive dental care but they are in need of further support from policy makers to enhance preventive dental programs in the Kingdom. Oral hygiene should be improved in the country by reaching out to the entire community through extensive and continued education programs.

Malariometric surveys generate data on malaria epidemiology and dynamics of transmission necessary for planning and monitoring of control activities. This study determined the prevalence of malaria and the knowledge, attitude, and practice (KAP) towards malaria infection in Ibeshe, a coastal community. The study took place during the dry season in 10 villages of Ibeshe. All the participants were screened for malaria. A semistructured questionnaire was used to capture sociodemographic data and KAP towards malaria. A total of 1489 participants with a mean age of 26.7 ± 20.0 years took part in the study. Malaria prevalence was 14.7% (95% CI 13.0-16.6%) with geometric mean density of 285 parasites/μL. Over 97% of participants were asymptomatic. Only 40 (2.7%) of the participants were febrile, while 227 (18.1%) were anemic. Almost all the participants (95.8%) identified mosquito bite as a cause of malaria, although multiple agents were associated with the cause of malaria. The commonest symptoms associated with malaria were hot body (89.9%) and headache (84.9%). Window nets (77.0%) were preferred to LLIN (29.6%). Malaria is mesoendemic in Ibeshe during the dry season. The participants had good knowledge of symptoms of malaria; however, there were a lot of misconceptions on the cause of malaria.

Environmental Factors and Zoonotic Pathogen Ecology in Urban Exploiter Species.

Knowledge of pathogen ecology, including the impacts of environmental factors on pathogen and host dynamics, is essential for determining the risk that zoonotic pathogens pose to people. This review synthesizes the scientific literature on environmental factors that influence the ecology and epidemiology of zoonotic microparasites (bacteria, viruses and protozoa) in globally invasive urban exploiter wildlife species (i.e., rock doves [Columba livia domestica], European starlings [Sturnus vulgaris], house sparrows [Passer domesticus], Norway rats [Rattus norvegicus], black rats [R. rattus] and house mice [Mus musculus]). Pathogen ecology, including prevalence and pathogen characteristics, is influenced by geographical location, habitat, season and weather. The prevalence of zoonotic pathogens in mice and rats varies markedly over short geographical distances, but tends to be highest in ports, disadvantaged (e.g., low income) and residential areas. Future research should use epidemiological approaches, including random sampling and robust statistical analyses, to evaluate a range of biotic and abiotic environmental factors at spatial scales suitable for host home range sizes. Moving beyond descriptive studies to uncover the causal factors contributing to uneven pathogen distribution among wildlife hosts in urban environments may lead to targeted surveillance and intervention strategies. Application of this knowledge to urban maintenance and planning may reduce the potential impacts of urban wildlife-associated zoonotic diseases on people.

In formulating the second national strategic plan for prevention of HIV/AIDS in the Islamic Republic of Iran a more evidence-based approach was needed. This paper reports on a systematic review of the local evidence about the determinants of HIV/AIDS transmission in 3 categories: poor knowledge and negative attitudes about HIV transmission; injection drug use; and sexual promiscuity. Of 93 reports reviewed, 53 met the inclusion criteria. Information about the prevalence and magnitude of effect for the 3 risk determinants at the national and regional level was scarce. Heterogeneity between studies, even in the same sub-population, was significant. An improved research base and better sharing of information are needed within countries of the Eastern Mediterranean Region.

Khanna, Rahul; Jariwala, Krutika

2012-01-01

In the past few decades, the prevalence of autism has increased tremendously in the United States. The prevalence of autism is now higher than the combined prevalence of juvenile diabetes, pediatric cancer, and pediatric AIDS. As health care professionals with a high visibility in a community, pharmacists are likely to encounter more and more families having a child affected by this disorder. The purpose of this study was to assess pharmacists' awareness and knowledge of autism. The study aimed to assess pharmacists' familiarity with autism symptoms, treatment medications, and community resources devoted to this disorder. Further, pharmacists' knowledge of common myths associated with autism, etiology, prognosis, and treatment were assessed. Using a cross-sectional design, an online survey of pharmacists registered in the state of Mississippi (MS) was conducted, using the Qualtrics software program. Descriptive analysis of study items was conducted. A total of 147 usable responses (5.8%) were received. The results indicated gaps in pharmacists' awareness and knowledge of autism. Approximately, 23% of pharmacists did not know that autism is a developmental disorder, and 32% did not believe that genetics has a major role in autism etiology. More than 18% believed that vaccines can cause autism. Most (>90%) felt that they could benefit from autism continuing education (CE). Policy makers and autism agencies should consider providing educational interventions or CE programs to increase pharmacists' awareness and knowledge of autism. Copyright © 2012 Elsevier Inc.

The objectives of this study were to assess the association between children and parents' knowledge of caries preventive practices, the parents' caries preventive oral health behaviours and children's caries preventive oral health behaviour and caries experience. Three hundred and twenty four participants aged 8-12 years, 308 fathers and 318 mothers were recruited through a household survey conducted in Suburban Nigeria. A questionnaire was administered to generate information on fathers, mothers and children's knowledge of caries prevention measures and their oral health behaviour. Clinical examination was conducted on the children to determine their dmft/DMFT. Analysis was conducted to determine the predictors of the children's good oral health behaviour. The mothers' oral health behaviours were significant predictors of the children's oral health behaviours. Children who had good knowledge of caries prevention measures had significant increased odds of brushing their teeth twice daily or more. The children's caries prevalence was 13.9%, the mean dmft was 0.2 and the mean DMFT was 0.09. None of the dependent variables could predict the presence of caries in children. The study highlights the effect of maternal oral health behaviour on the oral health behaviour of children aged 8 years to 12 years in suburban Nigeria. A pilot study is needed to evaluate how enhanced maternal preventive oral health practices can improve the oral health preventive practices of children.

Prevalence, determinants and systems-thinking approaches to optimal hypertension control in West Africa

PubMed Central

2014-01-01

Background In West Africa, hypertension, once rare, has now emerged as a critical health concern and the trajectory is upward and factors are complex. The true magnitude of hypertension in some West African countries, including in-depth knowledge of underlying risk factors is not completely understood. There is also a paucity of research on adequate systems-level approaches designed to mitigate the growing burden of hypertension in the region. Aims In this review, we thematically synthesize available literature pertaining to the prevalence of hypertension in West Africa and discuss factors that influence its diagnosis, treatment and control. We aimed to address the social and structural determinants influencing hypertension in the sub-region including the effects of urbanization, health infrastructure and healthcare workforce. Findings The prevalence of hypertension in West Africa has increased over the past decade and is rising rapidly with an urban-rural gradient that places higher hypertension prevalence on urban settings compared to rural settings. Overall levels of awareness of one’s hypertension status remain consistently low in West African. Structural and economic determinants related to conditions of poverty such as insufficient finances have a direct impact on adherence to prescribed antihypertensive medications. Urbanization contributes to the increasing incidence of hypertension in the sub-region and available evidence indicates that inadequate health infrastructure may act as a barrier to optimal hypertension control in West Africa. Conclusion Given that optimal hypertension control in West Africa depends on multiple factors that go beyond simply modifying the behaviors of the individuals alone, we conclude by discussing the potential role systems-thinking approaches can play to achieve optimal control in the sub-region. In the context of recent advances in hypertension management including new therapeutic options and innovative solutions to expand health workforce so as to meet the high demand for healthcare, the success of these strategies will rely on a new understanding of the complexity of human behaviors and interactions most aptly framed from a systems-thinking perspective.

This review aims to determine the prevalence and severity of oral health diseases in the Africa and Middle East region (AMER). The profile of oral diseases is not homogeneous across the AMER. There are large disparities between groups. Reliable data are scarce. The prevalence and severity of oral diseases appear to be increasing in the African region, as does associated morbidity. There are substantial differences in inequalities in oral health. Dental caries prevalence is less severe in most African countries than in developed countries, but the high rate of untreated caries reflects the limited resources available and difficulties of access and affordability to essential oral health care services. The prevalence of gingival inflammation is very high in all age groups in several African countries. The prevalence of maxillofacial trauma has increased in many countries, with a wide variation of the incidence and high prevalence of traumatic dental injuries in primary and permanent teeth. Orofacial clefts are among the most common birth defects. Annual incidence of oral cancer is estimated as 25 cases per 100,000 people in Africa. Noma is a major public health problem for the Middle East and North African (MENA) region. Data about human immunodeficiency virus/AIDS are limited, particularly in the MENA region. According to the World Health Organization Regional Committee for Africa report, some fundamental key basic knowledge gaps need to be underlined. They include inequalities in oral health, low priority for oral health, lack of adequate funding, inadequate dental student training, obstacles to medical and dental research, and poor databases. There are very few effective public prevention and oral health promotion programs in the AMER. Universal health coverage is not achievable without scientific research on the effectiveness of health promotion interventions. © International & American Associations for Dental Research 2015.

The incidence of oropharyngeal cancer (OPC) and a subset of oral cavity cancer (OCC) is increasing in the United States. To the authors' knowledge, the presumed growing prevalence of survivors of OPC and OCC has not been investigated to date. Retrospective analysis of Surveillance, Epidemiology, and End Results data (1975-2012) estimated changes in incidence, 5-year cause-specific survival, and prevalence for OPC and OCC. Changes in incidence, cause-specific survival and prevalence were estimated by linear regression and expressed as the percentage change (B). Differences in incidence trends over time were determined by joinpoint analysis. The incidence of OPC increased by 62.6% from 1975 through 2012. Notable increases in OPC incidence were observed among men, white individuals, and those of younger ages. The 5-year survival for OPC increased significantly for all sexes, races, and individuals aged >30 years, with white individuals and males experiencing the largest increase in survival. By contrast, the incidence of OCC declined by 22.3% during the same time period. OCC incidence decreased across all groups but increased among individuals aged 30 to 39 years. Significant increases in survival were observed for OCC, except for those who were female, black, and aged <40 years. The prevalence of survivors of OPC increased from 2000 to 2012 (B, 115.1 per 100,000 individuals per year; P<.0001), whereas the prevalence of survivors of OCC significantly decreased (B, -15.8 per 100,000 individuals per year; P<.0001). The prevalence of survivors of OPC is increasing, whereas the prevalence of survivors of OCC is declining. These data portend significant implications for long-term care planning for survivors of OPC and OCC. Cancer 2016;122:1380-1387. © 2016 American Cancer Society. © 2016 American Cancer Society.

Tonsilloliths and abnormal stylohyoid complex may have similar symptoms to others of different aetiology. Individuals with cleft lip and palate describe similar symptoms because of the anatomical implications that are peculiar to this anomaly. The aim of this study was to determine the prevalence of abnormal stylohyoid complex and tonsilloliths on cone beam computed tomography in individuals with cleft lip and palate. According to the inclusion and exclusion criteria, 66 CT scans out of of 2,794 were analysed, on i- Cat ® vision software with 0.8 index Kappa intra-examiner. The total prevalence of ossification of the incomplete stylohyoid complex in individuals with cleft lip and palate was 66.6%; the prevalence of these findings in females was 75% and 61.9% in males. The total prevalence of tonsilloliths was 7.5%. It is important to ascertain calcification of the stylohyoid complex and tonsilloliths in the radiological report, due to the anatomical proximity and similarsymptomatology to other orofacial impairments inindividuals with cleft lip and palate, focusing on females with oral cleft formation, patients with incisive trans foramen cleft and incisive post foramen cleft because they are more prevalent. Greater knowledge of the anatomical morphometry of individuals with cleft lip and palate greatly contributes towards the selection of clinical behaviours and the quality of life of these patients, since cleft lip and palateis one of the most common anomalies.

Allergic conditions have high prevalence in the general population. Misconceptions regarding the diagnosis and management of allergic disease among physicians can lead to suboptimal clinical care. To determine the extent of allergy-related knowledge deficits among physicians. Pediatric and internal medicine resident and attending physicians from 2 separate academic medical centers were asked to answer an anonymous electronic survey. Survey questions addressed 7 different allergy content areas. Four hundred eight physicians completed surveys (23.9% response rate). Respondents had few correct answers (mean ± SD 1.91 ± 1.43). Pediatric respondents had a larger number of correct answers compared with medicine-trained physicians (P < .001). No individual answered every survey question correctly, and 50 respondents (12.3%) had no correct answer. Three hundred seventy-eight respondents (92.6%) were unable to provide correct answers for at least 50% of survey questions. Level of residency training and prior rotation through an allergy and immunology elective correlated with a larger number of correct responses (P < .01). Only 1 survey question had an overall correct response rate higher than 50% (n = 261, 64%). Correct response rate was lower than 30% for 7 of the 9 possible questions. There are significant knowledge deficits in many areas of allergy-related content among pediatric and internal medicine physicians and across all levels of training and specialty. Given the prevalence of allergic conditions, the potential implications of a negative impact on clinical care are staggering. Copyright © 2015 American College of Allergy, Asthma & Immunology.

Risky sexual behaviors (RSB) are becoming an important problem all over the world. RSB are defined as behaviors leading to sexually transmitted diseases and unintended pregnancies. The objective of this study was to determine the prevalence and associated factors of RSB among undergraduate students in state universities of Western Province in Sri Lanka. A descriptive cross sectional study was conducted on1575 second and third year undergraduates using stratified cluster sampling of the selected universities. A pretested self-administered questionnaire was used to assess socio-demographic, knowledge attitudes and behavior on reproductive health. RSB was defined as reporting of one or more following behavior/s; having more than one sexual partner, use of alcohol or inability to use condom or other contraceptive methods in sexual activities. The results were expressed as prevalence and its 95% confidence interval (CI) of RSB. Multiple logistic regression was performed ascertain the association between RSB and possible associated factors. The results were expressed as adjusted odds ratios (AOR). Prevalence of RSB in last 1 year and 3 months periods were 12.4%, (95% CI: 11.8-13.1) and 12.1% (95% CI: 11.5-12.7) respectively. The significantly associated risk factors for RSB were, attended night clubs in last month (AOR = 3.58, 95% CI: 1.29-9.88), alcohol consumption within last 3 months (AOR = 2.67, 95% CI: 1.87-3.80) and good knowledge on condoms (AOR = 2.82, 95% CI: 1.94-4.10). Those who thought religion was very important to their lives (AOR = 0.68, 95% CI: 0.48-0.95) was a protective factor. Alcohol consumption and attending night clubs were associated with RSB. Necessary measures should be taken to reduce risk behaviors within university to reduce RSB.

Breast cancer epidemiological patterns vary in European countries, which present different incidence rates. Data have suggested that the reduction in breast cancer mortality is not only due to the early detection of the disease, but is, in almost equal part, due to screening and to the advances that have been made in molecular medicine and the development of novel therapies. The aim of the present study is to quantify the actual number of cases of breast cancer present in both of the sexes by calculating the prevalence of silent breast cancer in corpses. To achieve this quantification, bilateral subcutaneous radical mastectomies are performed in corpses of either sex above 40 years of age that lacked any clinical manifestation of the disease, and where the breast cancer or its complications was not the cause of death. Only five publications exist in the international literature based on medico-legal autopsies that were designed to define the ‘natural reservoir’ of the disease. To the best of our knowledge, the present study is the first one to appraise breast tissue via imaging by means of orienting the biopsy incision. In conclusion, to the best of our knowledge, the design of the present study is the first of its type, where image-guided biopsies are used to define the prevalence of silent breast cancer. The study aims to demonstrate that the ‘disease reservoir’ is, in reality, higher than was originally considered to be so. Furthermore, the study aims to contribute towards an improved definition of the disease by determining which tumour profiles potentially do not benefit from aggressive treatments (for example, in case where a high prevalence of low-grade ductal carcinoma in situ is to be detected). According to our pilot study, this analysis represents a feasible protocol. PMID:28781784

Chauhan, Astha; Nagarajappa, Sandesh; Dasar, Pralhad L; Mishra, Prashant

To determine and compare oral health status, knowledge and attitude among siblings of mentally disabled with siblings of normal healthy children. 240 study subjects consisting of 120 each of siblings of mentally disabled and normal, healthy children (control group) matched for age and gender were selected by convenience sampling. Oral health was assessed using the WHO-1997 proforma. A pretested questionnaire (30 items) was used for oral health knowledge and attitude assessment. Statistical analysis was performed using the chi-squared and Mann-Whitney tests. Caries prevalence among the siblings of mentally disabled and control group was 82% (mean DMFT 1.68 ± 1.18) and 45% (mean DMFT 0.58 ± 0.72), respectively (p < 0.05). The siblings of mentally disabled children also showed good oral health knowledge (mean 7.1 ± 1.4) and a positive attitude (p < 0.05). Siblings of mentally disabled children showed higher caries experience. Knowledge and attitude towards oral health was comparatively good among siblings of mentally disabled children. They exhibited favourable attitudes and involvement in helping their sibling to maintain oral health.

Despite the relatively high prevalence of aphasia, research indicates that, world-wide, public awareness of aphasia is lacking. Of the surveys that have been conducted internationally, none has studied the Canadian public's awareness of aphasia. The purpose of the present survey was to assess public awareness and basic knowledge of aphasia of individuals in southern Ontario, Canada. Using the same questionnaire that has been used in other countries, face-to-face surveys were conducted in public places (e.g. parks) at various locations in southern Ontario. Respondents were asked questions pertaining to their awareness and knowledge of aphasia. The number of surveys retained for analysis was 831. In addition to an evaluation of public awareness and knowledge of aphasia, the potential influences of age, gender, and occupation were analysed. For those who had heard of aphasia, questions were asked to determine how or where they had heard of aphasia. Consistent with the literature, overall public awareness and basic knowledge of aphasia in southern Ontario was found to be limited. The factors of age, gender and occupation were found to influence the results. This investigation supports the need for better promotion of aphasia awareness to the public in southern Ontario and, by extension, in Canada.

The purpose of this study is twofold: to evaluate the extent of knowledge possessed by young people residing in an urban sexually transmitted disease (STD) and AIDS epicenter about STDs, including AIDS; and to determine whether knowledge levels varied by age, gender, race/ ethnicity, and/or previous health instruction. A total of 867 adolescents (472 females and 395 males) attending a large public high school in New York City completed a self-administered survey. Levels of knowledge about AIDS transmission and prevention were high (mean percentage correct = 91.8%). Nonetheless, adolescent respondents locked awareness about the prevalence of common STDs, had limited understanding of the ways in which these diseases can be transmitted and prevented, and were unaware of potentially serious sequelae resulting from exposure to infectious agents (e.g., infertility from chlamydial infections). Young people who had taken a health education course in which STDs were discussed did slightly better on the knowledge survey than did their peers. While the prevention of HIV infection is, and should be, a national priority, more concerted efforts are needed to better educate young people about other STDs in the overall context of sexual health.

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practices and AIDS risk knowledge. Men in high AIDS-prevalence areas were found to have had a greater number of sexual partners, were more knowledgeable about AIDS, were much more likely to engage in low-risk practices (such as mutual masturbation or body rubbing), and had unprotected anal intercourse less frequently than gay men in smaller cities. The most common sexual activity among gay men in the larger city was mutual masturbation, a low-risk practice. The most common sexual activity among gay men in the smaller cities was unprotected anal intercourse. Increased efforts are needed to educate gay men and to promote risk behavior changes among those living in smaller cities and in communities outside the prominent AIDS epicenters. PMID:2502813

Herbal medication usage is prevalent in both developing and developed countries. The low level of awareness of the possible dangers of some herbs during pregnancy increases the risk of unwarranted sequelae. This manuscript describes the first study of herbal medication use among pregnant women in Saudi Arabia. It aims to determine the prevalence of herbal medication use during pregnancy, during labor and after delivery in the central region of Saudi Arabia. A cross-sectional descriptive study was conducted over a 5-month period from May 15 to October 15, 2016. A self-administered questionnaire was distributed at 4 main hospitals and 3 primary care centers in Riyadh and Al Kharj. Data from 612 participants were collected and analyzed. Descriptive statistics in the form of frequency and percentage were determined, and Chi-squared tests were performed. Of the 612 participants, 25.3%, 33.7% and 48.9% used herbs during pregnancy, during labor, and after delivery, respectively. The primary motives for using herbal medication during pregnancy, during labor and after delivery were to boost general health, ease and accelerate labor and clean the womb, respectively. There was a significant association between use during pregnancy and prior use (P = 0.001). Most pregnant women used herbs based on advice from family and friends (52.9%). Only 40.7% of pregnant women disclosed their herbal use to their doctors. The prevalence of herbal medication use among pregnant Saudi women in Riyadh and Al Kharj is relatively high. Doctors should be aware of evidence regarding the potential benefits or harm of herbal medication use during pregnancy.

Seasonal outbreaks of Lassa fever in West Africa cause significant morbidity and mortality across all ages. In addition to present efforts to raise awareness, school children can be targeted to become peer and family health educators. The study was carried out to determine the knowledge of Lassa fever among secondary school children, and household practices that increase risk of the infection. In a cross sectional survey, 561 secondary school students randomly selected from schools in Edo State were interviewed by means of a self - administered questionnaire that sought information on knowledge of Lassa fever and practices within the home that favour rodent contact . Data were analyzed using Statistical Package for Social Sciences version 15. Knowledge of Lassa fever was poor among 259 (49.4%) respondents, fair in 216 (41.2%) and good in 49 (9.4%). Female gender (< 0.01), monogamous family structure (p < 0.04) , and being in senior secondary class ( p=0.01) were predictors of high knowledge score. Self- reported Lassa fever risk conditions were found to be of low prevalence in 311(55.4%) and high in 250 (44.6%) homes, and associated with educational status of mother ( p=0.00) and father, (p =0.00). School children in endemic communities lack good knowledge of Lassa fever, but when properly guided, have the potential to become peer and family educators.

To determine the prevalence of domestic violence (physical, psychological or sexual) during pregnancy and to characterise these women. Pregnant women are not immune to domestic violence and therefore may be subject to any form of physical, psychological or sexual violence by partners. Health professionals' knowledge and awareness are important in the identification and intervention of pregnant women who experience domestic violence. Quantitative, descriptive, correlational study, using a nonprobabilistic convenience sample consisting of a total of 852 postpartum women, of whom 370 were experiencing domestic violence according to the criteria adopted through the modified scale of prevalence, applied between February-June 2012 in two Portuguese public health institutions. Authorisation was given by the Ethics Committees/Administration Councils of both institutions involved and the National Committee of Data Protection. The prevalence of DV during pregnancy was 43·4% (physical violence - 21·9%; psychological violence - 43·2%; and sexual violence - 19·6%). These women had the following profile: immigrant (OR = 5·70; IC95% 3·32-9·78), non-Caucasian (OR = 6·27; IC95% 3·76-10·46), single/divorced/widowed (OR = 2·28; IC95% 1·70-3·05), academic qualifications up to year 9 (OR = 4·94; IC95% 3·31-7·37); between 10-12 years of schooling (OR = 2·36; IC95% 1·70-3·29); unemployed (OR = 2·01; IC95% 1·50-2·69); and with a monthly income <1000 euros (OR = 1·90; IC95% 1·44-2·50). Through logistic regression, the following protective factors have been identified: nationality (Portuguese), race (Caucasian) and place of residence (city). Almost half of the sample had experienced some form of domestic violence. This is associated with certain sociodemographic factors identified in the study. Psychological violence was the most prevalent during pregnancy. Knowledge of the prevalence and characteristics of pregnant women who experience domestic violence is of paramount importance in planning appropriate strategies for their needs during pregnancy. Results indicate the need for nurses to intervene when warning signs of domestic violence against pregnant women are detected. © 2017 John Wiley & Sons Ltd.

Introduction. Parasitic diseases are the major causes of human health problem in Ethiopia. The high prevalence of parasitic infections is closely correlated with poverty, poor environmental hygiene, and impoverished health services. Objective. The study was conducted to assess the impact of health-conscious Awramba cooperative community and its neighboring communities on the prevalence of parasitic infections in South Gondar, Ethiopia. Methods. Single stool specimens were collected from 392 individuals from Awramba and the neighboring communities. Specimens were examined microscopically for the presence of parasites using microscopy. Questionnaire was administered to determine the knowledge attitude and practice (KAP) of study participants. Results. Of the total 392 study participants examined, 58(14.8%) were positive for malaria and 173 (44.1%) for intestinal parasites. The prevalence of malaria in Awramba community (5.1%) was less than that in neighboring communities (24.5%). The prevalence of parasitic infections in Awramba (18.8%) was less than that of the neighboring communities (69.4%). Conclusion. This study showed that good household and environmental hygiene, good toilet construction and usage, and proper utilization of ITN in Awramba cooperative community have significantly contributed to the reduction of the burden of parasitic infections. Thus, the positive achievement in reducing parasitic infections in Awramba cooperative community could be used as a model for affordable health intervention in the neighboring communities, in particular, and the whole country in general.

The prevalence of online modules for continuing education in the health professions has been increasing in recent years. However, the effectiveness of online modules for pharmacist learning has not been thoroughly studied. The primary aim of this study was to determine if providing education to pharmacists through a self-paced enhanced online module was non-inferior to a face-to-face learning module with respect to knowledge application on the topic of postoperative insulin dosing. Secondary aims were to determine pharmacists' knowledge gain and retention, as well as their satisfaction with the modules. The participants in this prospective, randomized, parallel-group non-inferiority trial were pharmacists in a large multicentre health region. Outcomes were measured by comparing scores obtained on pre- and post-module knowledge-assessment questionnaires. A between-group difference in change on knowledge application scores of less than 25 percentage points was the predetermined non-inferiority margin. A total of 74 pharmacists consented to participate, 38 randomly assigned to use the enhanced online module and 36 to attend the face-to-face learning session. For questions examining knowledge application, the mean improvement achieved by the online learning group was 26 percentage points greater than that achieved by the face-to-face learning group (95% confidence interval [CI] 25 to 27; p < 0.001). For questions testing knowledge gain, the improvement achieved by the online learning group was 7 percentage points less than that achieved by the face-to-face learning group (95% CI 2 to 12; p = 0.008). Therefore, the enhanced online module was deemed to be non-inferior to the face-to-face learning session in terms of knowledge application and knowledge gain. Insufficient data were available to analyze the secondary outcome of knowledge retention over time. Participant satisfaction was similar for the 2 groups (p = 0.62). The self-paced enhanced online module was non-inferior to facilitated face-to-face learning in terms of improving application and knowledge of insulin dosing. Pharmacists had similar levels of satisfaction with the 2 modes of learning.

Refusal bias in HIV prevalence estimates from nationally representative seroprevalence surveys.

To assess the relationship between prior knowledge of one's HIV status and the likelihood to refuse HIV testing in populations-based surveys and explore its potential for producing bias in HIV prevalence estimates. Using longitudinal survey data from Malawi, we estimate the relationship between prior knowledge of HIV-positive status and subsequent refusal of an HIV test. We use that parameter to develop a heuristic model of refusal bias that is applied to six Demographic and Health Surveys, in which refusal by HIV status is not observed. The model only adjusts for refusal bias conditional on a completed interview. Ecologically, HIV prevalence, prior testing rates and refusal for HIV testing are highly correlated. Malawian data further suggest that amongst individuals who know their status, HIV-positive individuals are 4.62 (95% confidence interval, 2.60-8.21) times more likely to refuse testing than HIV-negative ones. On the basis of that parameter and other inputs from the Demographic and Health Surveys, our model predicts downward bias in national HIV prevalence estimates ranging from 1.5% (95% confidence interval, 0.7-2.9) for Senegal to 13.3% (95% confidence interval, 7.2-19.6) for Malawi. In absolute terms, bias in HIV prevalence estimates is negligible for Senegal but 1.6 (95% confidence interval, 0.8-2.3) percentage points for Malawi. Downward bias is more severe in urban populations. Because refusal rates are higher in men, seroprevalence surveys also tend to overestimate the female-to-male ratio of infections. Prior knowledge of HIV status informs decisions to participate in seroprevalence surveys. Informed refusals may produce bias in estimates of HIV prevalence and the sex ratio of infections.

There are limited data regarding the prevalence of vancomycin-intermediate Staphylococcus aureus (VISA)/heterogeneous VISA (hVISA) among pediatric population. Our objective was to determine the distribution of vancomycin and daptomycin minimum inhibitory concentrations (MICs) and explore the phenomenon of vancomycin MIC creep and the VISA/hVISA prevalence among the methicillin-resistant Staphylococcus aureus (MRSA) strains belonging to pediatric population by population analysis profile-area under the curve (PAP-AUC) and Etest macromethod. Vancomycin and daptomycin susceptibilities of 94 pediatric isolates of MRSA were tested by broth microdilution (BMD) and Etest methods. To determine the prevalence of VISA/hVISA, Etest macromethod and PAP-AUC was performed on all isolates. All isolates were susceptible to vancomycin and daptomycin by both BMD and Etest methods. Twenty-eight (29.8%) isolates had vancomycin MICs of 2 μg/ml by BMD. No increase in vancomycin MICs was observed over time. There were no VISA among 94 MRSA tested but 20 (21.3%) hVISA isolates were identified by PAP-AUC. Results of Etest macromethod were compared to PAP-AUC. Etest macromethod was 60.0% sensitive and 90.5% specific. The hVISA isolates represented 53.6% of isolates with vancomycin MICs of 2 μg/ml. Also, 75% of hVISA isolates had vancomycin MICs of 2 μg/ml. To our knowledge, this is the first study investigating the prevalence of VISA/hVISA among MRSA isolated from pediatric patients by PAP-AUC method. Based on our findings, MRSA isolates, which have vancomycin MIC of 2 μg/ml can be investigated for the presence of hVISA. In this study, daptomycin showed potent activity against all isolates and may represent a therapeutic option for MRSA infections.

This study was designed to determine the prevalence of and risk factors for schistosomiasis among a group of preschool children in Malawi. Schistosomiasis burden among preschoolers in Malawi is not well documented in the literature. This study used field research (in the form of a snail survey), laboratory work (urinalysis and microscopy for parasite identification), and questionnaire-guided interviews to determine the prevalence of and risk factors for urinary schistosomiasis among children, aged between 6 and 60 months, in Malengachanzi, Nkhotakota District, Malawi. Urinary schistosomiasis prevalence among preschool children was 13%. Of the factors evaluated, only age (P = 0.027) was statistically significantly associated with urinary schistosomiasis risk. Four-year-old preschool children were five times more likely to contract urinary schistosomiasis than twoyear-old children (odds ratio [OR] = 5.255; 95% confidence interval [CI] = 1.014-27.237; P = 0.048). Increased contact with infested water among older children likely explains much of their increased risk. Infestation was evidenced by the presence of infected Bulinus globosus snails in the water contact points surveyed. Multiple regression analysis showed that visiting water contact sites daily (OR = 0.898, 95% CI = 0.185-4.350, P = 0.894), bathing in these sites (OR = 9.462, 95% CI = 0.036-0.00, P = 0.430) and lack of knowledge, among caregivers, regarding the causes of urinary schistosomiasis (OR = 0.235, 95% CI = 0.005-1.102, P = 0.066) posed statistically insignificant risk increases for preschoolers contracting urinary schistosomiasis. Urinary schistosomiasis was prevalent among preschool children in Malengachanzi, Nkhotakota District. Contact with infested water puts these children and the general population at risk of infection and reinfection. Inclusion of preschool children in treatment programmes should be considered imperative, along with safe treatment guidelines. To prevent infection, the population in the area should be provided with health education and safe alternative water sources.

Health and safety instructions are important components of occupational prevention. Albeit instruction is mandatory in most countries, research suggests that safety knowledge varies among the workforce. We analysed a large European sample to explore if all subgroups of employees are equally reached. In a comparative perspective, we also investigated if country-level determinants influence the variance of safety knowledge between countries. We used data on 24,534 employees from 27 countries who participated in the 2010 European Working Conditions Survey. Safety knowledge was measured as self-assessed quality of safety information. Country-level determinants were added from Eurostat databases (gross domestic product) and the European Survey of Enterprises on New and Emerging Risks (ESENER) study (% companies with A: safety plan or B: a labour inspectorate visit). Associations between knowledge, sociodemographic, occupational characteristics and macrodeterminants were studied with hierarchical regression models. In our sample, 10.1% reported a low degree of health and safety knowledge. Across all countries, younger workers, lower educated workers, production workers, private sector employees, those with less job experience or a temporary contract, or those who work in small businesses were more likely to report low levels of information. Moreover, low information prevalence varied by country. Countries with a high proportion of companies with a safety plan and recent labour inspectorate on-site visits had higher proportions of informed workers. A vast majority reported to be well informed about safety risks but systematic inequalities in the degree of knowledge between subgroups were evident. Further efforts on the workplace, the organisational and the political level are needed to universally implement existing occupational safety regulations.

Bhimani, Rozina

2016-01-01

The incidence and prevalence of work-related musculoskeletal nursing injuries is a top concern for nurses. These injuries are thought to be a dynamic interplay of multiple factors. A literature review reveals a knowledge gap in understanding context-specific patterns of nursing injuries. Using a cross-sectional descriptive research design, 58 rehabilitation nurses participated in this study. Anonymous paper surveys were sent to all rehabilitation nursing personnel on the unit. Six themes emerged: lack of time and help, patient acuity, ergonomics, body movement issues, knowledge deficit, and communication. Nursing input is critical in understanding and reducing context-specific work-related musculoskeletal injuries. Further research that includes nursing voices is advocated. Rehabilitation nursing injuries appear to be a complex interaction of multiple determinants; therefore, multifaceted solutions using a quality improvement lens are recommended to improve the working conditions on the units. © 2014 Association of Rehabilitation Nurses.

Interaction between HIV awareness, knowledge, safe sex practice and HIV prevalence: evidence from Botswana.

PubMed

Ray, Ranjan; Sinha, Kompal

2012-05-01

This paper makes methodological and empirical contributions to the study of HIV in the context of Botswana, a country with high HIV prevalence. Comparable evidence is presented from India to put the Botswana results in perspective. The results point to the strong role played by affluence and education in increasing HIV knowledge, promoting safe sex and reducing HIV prevalence. The study presents African evidence on the role played by the empowerment of women in promoting safe sex practices such as condom use. The lack of significant association between HIV prevalence and safe sex practice points to the danger of HIV-infected individuals spreading the disease through multiple sex partners and unprotected sex. This danger is underlined by the finding that females with multiple sex partners are at higher risk of being infected with HIV. These results take on special policy significance in the context of Botswana, where the issue of multiple sex partners has not been adequately addressed in the programme to contain the spread of HIV.

The purpose of this analysis was to estimate human immunodeficiency virus (HIV) prevalence and testing patterns among injection drug users (IDUs) in St. Petersburg, Russia. HIV prevalence among 387 IDUs in the sample was 50%. Correlates of HIV-positive serostatus included unemployment, recent unsafe injections, and history/current sexually transmitted infection. Seventy-six percent had been HIV tested, but only 22% of those who did not report HIV-positive serostatus had been tested in the past 12 months and received their test result. Correlates of this measure included recent doctor visit and having been in prison or jail among men. Among the 193 HIV-infected participants, 36% were aware of their HIV-positive serostatus. HIV prevalence is high and continuing to increase in this population. Adequate coverage of HIV testing has not been achieved, resulting in poor knowledge of positive serostatus. Efforts are needed to better understand motivating and deterring factors for HIV testing in this setting. PMID:18843531

Alarming Prevalence of Emergency Hypertension Levels in the General Public Identified by a Hypertension Awareness Campaign.

2017-03-01

Hypertension is a major cause of mortality and morbidity today. The "silent" nature of hypertension makes it critical to determine its prevalence and its severity in the general public and to identify strategies to identify people unaware of its presence. A mobile hypertension awareness campaign was created to: (i) determine the prevalence and types of hypertension in an urban North American center, (ii) increase hypertension awareness, and (iii) identify reasons for lack of therapy adherence. Mobile clinics were provided at shopping malls, workplaces, hospitals, and community centres to measure blood pressure in the public. Blood pressure recordings were done on a voluntary basis. Of 1097 participants, 50% presented with high blood pressure which was higher than expected. Of particular clinical significance, an unexpectedly large number of participants (2%) exhibited a hypertensive urgency/emergency. Most of these people were not adherent to medications (if their hypertension was detected previously), were unaware of their hypertensive state, and/or unwilling to acknowledge or ignored the clinical significance of the extremely high blood pressure readings. Reasons for lack of adherence included: denial, being unaware of health consequences, and proper management of hypertension. A relatively large segment of an urban population lives unaware of severe emergency levels of hypertension. A public mobile hypertension clinic provides a valuable strategy for identifying hypertension in the general public and for knowledge translation of hypertension management. © American Journal of Hypertension, Ltd 2017.

The aim of this work was to conduct a radiological micro-CT study and meta-analysis to determine the morphological features of the root canal anatomy of the maxillary molars. The radiological study included micro-CT scans of 110 maxillary first molars and 98 maxillary second molars. To identify articles eligible for inclusion in our meta-analysis, PubMed, Embase, and Web of Science were search comprehensively. The following data were extracted: study type (cadaveric, intraoperative or imaging), Vertucci types of canal configuration, presence/number of canals, roots, apical foramina, apical deltas, and inter-canal communications. The mesiobuccal root was the most variable with respect to canal configuration, type I being the most common configuration followed by type II and type IV. Type I was the most common canal configuration in the distobuccal and palatal root. Regarding the number of canals in the maxillary first and second molars, one canal was most prevalent in all roots of the three molars, except for the mesiobuccal root of maxillary first molar, in which two canals were most prevalent. The most prevalent number of roots in all maxillary molars was three. Knowledge of endodontic anatomy determines the parameters of root canal treatment and significantly affects the probability of success. It is therefore especially important to know the morphology of the root canal system in order to perform endodontic treatment correctly. This article is protected by copyright.

The prevalence of diabetes mellitus is rapidly increasing particularly in developing countries. The aim of this study was to assess the knowledge and self-care practices of diabetes patients and to assess the contribution of the education to this knowledge level and glycemic control. We formed patient groups consisting of 15-30 diabetic patients. First, patients were surveyed using a diabetes self-care knowledge questionnaire (DSCKQ-30). Sunsequently, a standard PowerPoint presentation about diabetes self-management was made to the patients who were then surveyed again using DSCKQ-30. All patients were invited to hospital to measure their control glycated hemoglobin (HbA1c) level 3 months later. Of the total 364 participants, 62.9% were females. Significant increases in the percentage of correct responses were determined in all components between, before and after education. There was a significant decline of 1.1 in HbA1c levels after 3 months of education. Married or active working patients had a better understanding of the education about diabetes and had a greater knowledge of self-care management regardless of their level of education or income. Education about diabetes can significantly improve knowledge of self-care management and can help in achieving glycemic control. Continuing education about self-care management and complications is crucial and this should be accompanied by a regular assessment of pateients' diabetic knowledge.

Understanding the way in which societal and individual factors interact to shape sex workers' vulnerability would better inform interventions. 326 female sex workers, recruited throughout Goa using respondent-driven sampling, completed interviewer-administered questionnaires. Biological samples were tested for Trichomonas vaginalis, Neisseria gonorrhoea, Chlamydia trachomatis and antibodies to herpes simplex virus type 2 (HSV-2) and HIV. Multivariate analysis was used to define the determinants of HIV infection and any bacterial sexually transmitted infection (STI). Infections were common, with 25.7% prevalence of HIV and 22.5% prevalence of bacterial STI; chlamydia 7.3%, gonorrhoea 8.9% and trichomonas 9.4%. Antibodies to HSV-2 were detected in 57.2% of women. STI were independently associated with factors reflecting gender disadvantage and disempowerment, namely young age, lack of schooling, no financial autonomy, deliberate self-harm, sexual abuse and sex work-related factors, such as having regular customers and working on the streets. Other factors associated with STI were Goan ethnicity, not having an intimate partner and being asymptomatic. Having knowledge about HIV and access to free STI services were associated with a lower likelihood of STI. HIV was independently associated with being Hindu, recent migration to Goa, lodge or brothel-based sex work and dysuria. Sex workers working in medium prevalence states of India are highly vulnerable to HIV and STI and need to be rapidly incorporated into existing interventions. Structural and gender-based determinants of HIV and STI are integral to HIV prevention strategies.

Afghanistan has some of the worst maternal and infant mortality indicators in the world and malaria is a significant public health concern. Study objectives were to assess prevalence of malaria and anaemia, related knowledge and practices, and malaria prevention barriers among pregnant women in eastern Afghanistan. Three studies were conducted: (1) a clinical survey of maternal malaria, maternal anaemia, and neonatal birthweight in a rural district hospital delivery-ward; (2) a case-control study of malaria risk among reproductive-age women attending primary-level clinics; and (3) community surveys of malaria and anaemia prevalence, socioeconomic status, malaria knowledge and reported behaviour among pregnant women. Among 517 delivery-ward participants (1), one malaria case (prevalence 1.9/1000), 179 anaemia cases (prevalence 346/1000), and 59 low-birthweight deliveries (prevalence 107/1000) were detected. Anaemia was not associated with age, gravidity, intestinal parasite prevalence, or low-birthweight at delivery. Among 141 malaria cases and 1010 controls (2), no association was found between malaria infection and pregnancy (AOR 0.89; 95 % CI 0.57-1.39), parity (AOR 0.95; 95 % CI 0.85-1.05), age (AOR 1.02; 95 % CI 1.00-1.04), or anaemia (AOR 1.00; 95 % CI 0.65-1.54). Those reporting insecticide-treated net usage had 40 % reduced odds of malaria infection (AOR 0.60; 95 % CI 0.40-0.91). Among 530 community survey participants (3), malaria and anaemia prevalence were 3.9/1000 and 277/1000 respectively, with 34/1000 experiencing severe anaemia. Despite most women having no formal education, malaria knowledge was high. Most expressed reluctance to take malaria preventive medication during pregnancy, deeming it potentially unsafe. Given the low malaria risk and reported avoidance of medication during pregnancy, intermittent preventive treatment is hard to justify or implement. Preventive strategy should instead focus on long-lasting insecticidal nets for all pregnant women.

HIV, STI prevalence and risk behaviours among women selling sex in Lahore, Pakistan

PubMed Central

2011-01-01

Background More than 340 million cases of curable sexually transmitted infections (STIs) were estimated to have occurred worldwide in 1995. Previous studies have shown that the presence of other concomitant STIs increases the likelihood of HIV transmission. The first national study of STIs conducted in Pakistan in 2004 revealed a high burden of STIs among women selling sex. The HIV epidemic in Pakistan has thus far followed the "Asian epidemic model". Earlier studies among women selling sex have shown a low prevalence of HIV coupled with a low level of knowledge about AIDS. The aim of our study was to estimate the prevalence of HIV and STIs, and assess knowledge and risk behaviours related to HIV/STI, among women selling sex in Lahore, Pakistan. Methods A total of 730 participants were recruited through respondent-driven sampling. The participants were women selling sex in three areas (referred to as "A", "B", and "C") of Lahore. A structured questionnaire addressing demographic information, sexual life history, sexual contacts, and knowledge and practices related to HIV/STI prevention was administered by face-to-face interview. Biological samples were obtained from all participants and tested for HIV, Treponema pallidum, Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. Pearson's chi-square and multivariable logistic regression analysis were performed to test associations between potential risk factors and specified diagnosed infections. Results The prevalence of HIV infection was 0.7%, T pallidum 4.5%, N gonorrhoeae 7.5%, C trachomatis 7.7% and T vaginalis 5.1%. The participants had been selling sex for a median period of seven years and had a median of three clients per day. Sixty five percent of the participants reported that they "Always use condom". The median fee per sexual contact was Rs. 250 (3 Euro). Compared to Areas A and C, women selling sex in Area B had a significantly higher risk of chlamydial infection, gonorrhoea and trichomoniasis. Among the participants, 37% had correct knowledge about HIV/AIDS transmission and its prevention. Conclusions The prevalence of HIV was <1%, and of any other STI 18.5% among participating women selling sex in Lahore, Pakistan. A reasonably high condom use, a relatively low number of sexual partners, and a relatively low prevalence of STIs might have contributed to the low HIV prevalence. PMID:21569319

The objectives were to determine the prevalence and associated factors for smoking among university students in Malaysia. A cross-sectional study was conducted among 199 students in the period from December of academic year 2009 until April of academic year 2010 in Management and Science University (MSU), Shah Alam, Selangor, Malaysia. The questionnaire was distributed randomly to all faculties of MSU by choosing one of every 3 lecture rooms, as well as the library and cafeterias of the campus randomly by choosing one from every 3 tables. Questions concerned socio-demographic variables, knowledge, attitudes and practice toward smoking. Participant's consent was obtained and ethical approval was provided by the ethics committee of the University. Data entry and analysis were performed using descriptive statistics, chi square test, Student t- test and logistic multiple regression with the SPSS version 13.0, statistical significance being concluded at p < 0.05. About one third of students were smokers (29%). The most important reason of smoking was stress (20%) followed by 'influenced by friends' (16 %). Prevalence of smoking was significantly higher among male and those in advanced semesters (p = >0.001, p = 0.047). Smokers had low level of knowledge (p < 0.05), had wrong beliefs on smoking (p < 0.05), and negative attitude toward tobacco control policies compared to non smokers (p < 0.05). On multiple logistic regression, significant predictors of smoking in the model were gender (p = 0.025), age (p = 0.037), semester of study (p = 0.025) and attitude toward smoking (p < 0.001). This study found that 29% of university students were smokers. Males and students in advanced semesters were more likely to smoke. The results provide baseline data to develop an anti-smoking program to limit smoking in the university by implementing policies against smoking.

School children have been increasingly recognized as health messengers for malaria control. However, little evidence is available. The objective of this study was to determine the impact of school-based malaria education intervention on school children and community adults. This study was conducted in the Dangme-East district of the Greater Accra Region, Ghana, between 2007 and 2008. Trained schoolteachers designed participatory health education activities and led school children to disseminate messages related to malaria control to their communities. Three schools and their respective communities were chosen for the study and assigned to an intervention group (one school) and a control group (two schools). Questionnaire-based interviews and parasitological surveys were conducted before and after the intervention, with the intervention group (105 children, 250 community adults) and the control group (81 children, 133 community adults). Chi-square and Fisher's Exact tests were used to analyse differences in knowledge, practices, and parasite prevalence between pre- and post-intervention. After the intervention, the misperception that malaria has multiple causes was significantly improved, both among children and community adults. Moreover, the community adults who treated a bed net with insecticide in the past six months, increased from 21.5% to 50.0% (p < 0.001). Parasite prevalence in school children decreased from 30.9% to 10.3% (p = 0.003). These positive changes were observed only in the intervention group. This study suggests that the participatory health education intervention contributed to the decreased malaria prevalence among children. It had a positive impact not only on school children, but also on community adults, through the improvement of knowledge and practices. This strategy can be applied as a complementary approach to existing malaria control strategies in West African countries where school health management systems have been strengthened.

Seborrheic dermatitis (SD) is considered the second most frequently dermatosis associated with the genus Malassezia but little is the knowledge about the epidemiology of this association. To determinate the prevalence of Malassezia species associated with SD and to analyse their distribution according to the location of the lesion on the body. This study was performed in Resistencia city, located in a subtropical area in northeast Argentina. In this study, 226 skin samples from patients with lesions compatible with SD were studied. Age, gender and body sites lesion were recorded. Strains were identified by PCR-RFLP. One hundred and thirty-one positive cultures were obtained. Association of 2 species was detected in 10 cases; therefore, 141 strains were isolated. Malasezzia globosa (43.3%) was the most frequent species isolated, followed by Malasezzia furfur (20.6%), Malasezzia sympodialis (17%) and Malasezzia restricta (16.3%). Three isolates of Malasezzia slooffiae (2.1%) and one of Malasezzia pachydermatis (0.7%) were obtained. Statistical significance (P<0.05) was found between M. globosa and scalp. Malasezzia restricta was isolated only in head areas. This study suggests M. globosa is the most related species to SD. The prevalence of other species is different from that reported by other authors. Only M. globosa and M. restricta presented a pattern of relationship with the body sites of the lesions. It is noteworthy is the isolation of the zoophylic species M. pachydermatis. The Malassezia genus ecology and the pathogenic role of its species are still under study. This work is a contribution to this knowledge. Copyright © 2012 Revista Iberoamericana de Micología. Published by Elsevier Espana. All rights reserved.

A coprological survey to know the presence of gastro-intestinal nematode parasites infecting sheep was done in Galicia (NW Spain), an area with Atlantic climate where sheep production is replacing cattle due to the Agricultural Community Politics of the European Union. From September 2001 to November 2002, 1710 faecal samples were randomly collected from 49 sheep farms and examined by using the flotation technique to determine the prevalence of gastro-intestinal nematode parasites. The sheep-level prevalence was 100%, and the genera identified were Chabertia, Cooperia, Haemonchus, Nematodirus, Oesophagostomum, Teladorsagia, Trichostrongylus and Trichuris spp. A questionnaire was distributed to the farmers (at the same time as sampling) about parasite-control practices during the year before sampling (2000). Ninety percent (95% CI 81%, 98%) of the farmers said they used antiparasitic drugs occasionally, but none of them asked for a coprological analysis prior to the treatment and the efficacy of the drugs was never evaluated. A higher median EPG was observed in the treated sheep (163) than in the untreated ones (26). Chemotherapy was the only parasite-control practice. Flocks that treated according to the farmer's previous experience had higher median EPG (236) than other flocks (185 following the prescription of their veterinary clinician and 232 based on the commercial agent's counsel). Typically, one benzimidazole-treatment per year was applied in autumn and non-veterinary counsel was used. Sheep treated with imidotiazoles had lower EPG (144) than other drugs (164 for the benzimidazoles and 166 for the macrocyclic lactones). We found a higher median EPG in the sheep receiving two treatments/year (175) than in those treated only once per year (156). These results suggest lack of knowledge about worm-control strategies and anthelmintic use or unwillingness to apply such knowledge.

Sexual self-efficacy (SSE) - one's confidence in their ability to perform given sexual behaviours, has been shown to predict adolescents' HIV-prevention practices (e.g., Condom use). Few studies within sub-Saharan Africa, where HIV incidence and prevalence disproportionately affects young women, have examined gendered differences in SSE. We used multivariable logistic regression to identify correlates of high-SSE separately among adolescent men and women (aged 14-19) in Soweto, South Africa using a previously validated SSE scale (high-SSE [>3/6 items]; study-alpha = 0.75). SSE scale items assessed self-efficacy related to sexual refusal and condom use. Adolescent women were significantly more likely to report high-SSE than adolescent men (72.3% versus 49.5%; p < 0.01). High-SSE among adolescent men was associated with more positive beliefs about sexual relationships and negatively associated with probable depression. High-SSE among adolescent women was associated with increased HIV knowledge, more positive beliefs about condom use and sexual relationships, having an adult in the home, and negatively associated with being an older adolescent (16-17 versus ≤15), and ever experiencing physical violence. Differences in prevalence and correlates of SSE among adolescent men and women in South Africa highlight important areas for gender-sensitive interventions. Targeted efforts to reduce negative sexual beliefs, improve HIV knowledge and mental well-being may improve SSE and thus the uptake of HIV-prevention practices among adolescent men. For adolescent women, findings indicate programming should move beyond individual-levels determinants of behaviour to focus on improving enabling environments (e.g., Reduced violence and improved family relationships) in which sexual agency can be enacted.

We assessed the prevalence of breastfeeding and its determinants and mothers' knowledge and practices towards this issue among 354 women attending primary health centres for their child's 6- month vaccination in the region of Monastir in 2008. The mean age of the women was 30 (SD 5.5) years. Most (90.8%) knew that breastfeeding helped prevent infections in babies but only 38.5% knew that breast milk supplies all infant feeding needs until 6 months of age. While was 94.4% breastfed their babies to start, only 1.9% continued exclusive breastfeeding until 6 months. Main reasons for stopping breastfeeding were perceived breast milk insufficiency followed by return to work. Exclusive breastfeeding over 3 months was associated with skin-to-skin contact (OR = 1.93; 95% CI: 1.016-3.69) and mothers' knowledge about breast milk benefits (OR = 2.8; 95% CI: 1.2-6.6). Early weaning was related to using pacifiers and breast-milk substitutes (OR = 0.17; 95% CI: 0.08-0.36 and OR = 0.14; 95% CI: 0.05-0.38 respectively).

The objective of this study was to determine the knowledge and attitudes of practicing Nigerian lawyers towards issues relating to reproductive health and reproductive rights, and their opinions about abortion law reform. It was a population- based study which consisted of interviews with practicing lawyers in north-east Nigeria. The results showed poor knowledge of issues related to reproductive health and reproductive rights among the lawyers. However, the majority (56.9%) disagreed that a woman can practice family planning without the consent of her husband. The prevalence of contraceptive use among the lawyers was low and attitude to abortion law not satisfactory. Only few lawyers (22.4%) supported safe abortion in cases of failed contraception. We conclude that reproductive health advocates must target legal professionals with a view to educating them on issues relating to sexual and reproductive health and rights. Lawyers in Nigeria should undergo capacity building in reproductive health laws and be encouraged to specialize in reproductive rights protection as obtainable in other developed countries.

Migrant men who have sex with men (MSM) have a higher predisposition for HIV transmission. We aimed to determine and compare the prevalence and trends of HIV, Syphilis, and HCV between migrant and resident MSM in Shandong, China. A serial cross-sectional study was conducted in eight cities in Shandong, China from 2010 to 2014. The surveys collected information on demographics, HIV-related knowledge, and HIV-related behaviors including the serologic status of HIV, syphilis, and HCV. Bivariate and multivariable logistic regressions were used to determine differences between migrant and resident MSM. The overall prevalence of HIV among the 15,705 MSM (14120 were resident, 1580 were migrant and 5 were missing) was 2.6%, with an increase of 1.0% in 2010 to 4.4% in 2014. Prevalence of HIV was higher among migrant MSMs (5.5%) compared to resident MSMs (2.3%). Compared to residents, migrants also had higher prevalence of syphilis (7.5% vs 4.9%) and HCV (1.1% vs 0.6%). We found that there was an increase in the proportion of migrant MSM engaging in anal sex [adjusted OR (AOR) = 1.41 in migrants vs 1.12 in residents], condom use during last anal sex (AOR = 1.14 in residents, P for trend = 0.32), consistent condom use (AOR = 1.04 residents, P for trend = 0.11) and drug use (AOR = 1.51 in migrants and 1.29 among residents). Except in the year 2011, receiving some health services in last year was significant for people who were HIV-positive compared to negative. (P for trend <0.05). Prevalence of HIV increased in resident as well as migrant MSMs. The migrant MSMs had higher STIs compared to resident MSMs and therefore, should be targeted for effective interventions aimed at reducing their risk behaviors. Deeper understanding of the role of migration in health issues is required for combating the persistently high and gradually increasing HIV burden in MSM in China.

Factors associated with violence and the abuse of older adults are understudied and its prevalence in Mexico has not been reported. The aim of this study was to identify the prevalence and factors associated with violence and abuse of older adults in Mexico. We used Mexico's 2012 National Health and Nutrition Survey, which included a sample of 8,894 individuals who are 60 years or older and who self-reported a negative health event related to robbery, aggression or violence in the previous 12 months. We used chi-squared test and Fisher's exact test to analyze the variables related to violence. Adjusted estimates were completed with multiple logistic regression models for complex surveys. The prevalence of violence was 1.7 % for both men and women. In 95 % of the cases, the aggression was from an unknown party. Verbal aggressions were the most prevalent (60 %). Among men, physical aggression was more common. Violence frequently occurred in the home (37.6 %); however, men were primarily assaulted in public places (42.4 %), in comparison to women (30.7 %). There were also differences in the risk factors for violence. Among men, risk was associated with younger age (60-64 years), higher education (secondary school or above) and higher socioeconomic status. Among women, risk was associated with depression, not being the head of the family, and region of the country. Violence against older adults presents differently for men and women, which means it is necessary to increase knowledge about the dynamics of the social determinants of violence, particularly in regards to the role of education among men. The relatively low prevalence found in this study may reflect the difficulty and fear of discussing the topic of violence. This may occur because of cultural factors, as well as by the perception of helplessness perpetuated by the scarce access to social programs that ensure protection and problem solving with regards to the complex social determinants of individual and family violence that this population group endures.

Background Data on sociological and behavioural aspects of malaria, which is essential for an evidence-based design of prevention and control programmes, is lacking in Bangladesh. This paper attempts to fill this knowledge gap by using data from a population-based prevalence survey conducted during July to November 2007, in 13 endemic districts of Bangladesh. Methods A two-stage cluster sampling technique was used to select study respondents randomly from 30 mauzas in each district for the socio-behavioural inquiry (n = 9,750). A pre-tested, semi-structured questionnaire was used to collect data in face-to-face interview by trained interviewers, after obtaining informed consent. Results The overall malaria prevalence rate in the 13 endemic districts was found to be 3.1% by the Rapid Diagnostic Test 'FalciVax' (P. falciparum 2.73%, P. vivax 0.16% and mixed infection 0.19%), with highest concentration in the three hill districts (11%). Findings revealed superficial knowledge on malaria transmission, prevention and treatment by the respondents. Poverty and level of schooling were found as important determinants of malaria knowledge and practices. Allopathic treatment was uniformly advocated, but the 'know-do' gap became especially evident when in practice majority of the ill persons either did not seek any treatment (31%) or practiced self-treatment (12%). Of those who sought treatment, the majority went to the village doctors and drugstore salespeople (around 40%). Also, there was a delay beyond twenty-four hours in beginning treatment of malaria-like fever in more than half of the instances. In the survey, gender divide in knowledge and health-seeking behaviour was observed disfavouring women. There was also a geographical divide between the high endemic south-eastern area and the low-endemicnorth-eastern area, the former being disadvantaged with respect to different aspects of malaria studied. Conclusion The respondents in this study lacked comprehensive knowledge on different aspects of malaria, which was influenced by level of poverty and education. A gender and geographical divide in knowledge was observed disfavouring women and south-eastern area respectively. They preferred allopathic treatment for malaria, although a substantial proportion did not seek any treatment or sought self-treatment for malaria-like fever. Delay in seeking care was common. The implications of these findings for programme development are discussed. PMID:19640282

Objectives: Sri Lanka experienced the worst ever outbreak of leptospirosis in 2008. One major determinant of control and prevention of communicable diseases is public awareness on the disease. The purpose of the present study was to determine the awareness on leptospirosis among public Sri Lanka. Methods: A national household survey was carried out as a part of research methodology training of first year medical undergraduates in Rajarata Medical School. Each student visited 10 households surrounding his/her house to complete the interviewer administered questionnaire. The questionnaire was based on the factsheet published by the Epidemiology Unit for public health. Results: Altogether 602 participants from 14 districts participated in the study. Of them 93.7% were aware of rat as a reservoir animal, but only 3% were aware of the role of cattle and buffalo. Contact with infected water as a mode of transmission was reported by 57.9% of the population. Only 30.8% of the subjects were aware of that the infection can go through skin breeches. Farming as a risk activity was reported by 63.5% of the patients, but knowledge on other exposure activities were less than 20%. Paddy field work and cleaning garbage were correctly identified as risk occupations by 89.7% and 27.6% of the sample, respectively. Respondents were aware of fever (86%), malaise (30.8%), headache (29.6%) and muscle tenderness (28.8%) as main clinical features of the disease. Most of them (73.7%) knew leptospirosis as a lethal condition and 39.5% were aware of chemoprophylaxis. Conclusions: Although there is not adequate information on MDD prevalence in some areas of Iran, the overall current prevalence of MDD in the country is high and females are at the greater risk of disease.

Parasites have a profound impact on wildlife population dynamics. However, until some years ago, studies on the occurrence and prevalence of wildlife parasites were neglected comparatively with the studies on humans and domestic animals. In this study, we determined the parasite prevalence of two sympatric wild canids: the endangered Iberian wolf (Canis lupus signatus) and the widespread red fox (Vulpes vulpes), in central Portugal. From November 2014 to July 2015, fresh fecal samples from both species were collected monthly in several transects distributed throughout the study area. All samples were submitted to several coprological techniques. In total, 6 helminth parasites (Crenosoma vulpis, Angiostrongylus vasorum, Toxocara canis, Trichuris vulpis, Ancylostomatidae, Toxascaris leonina), and a protozoa (Balantidium coli) were identified based on size and morphology. The red fox was infected by seven different parasites while the Iberian wolf was infected by four. All parasites present in wolf were also present in the red fox. C. vulpis had the higher prevalence in red fox, while Ancylostomatidae were the most prevalent parasites in wolf. To our knowledge, this is the first study in this isolated subpopulation of the Iberian wolf. Our results show that both carnivores carry parasites that are of concern as they are pathogenic to humans and other wild and domestic animals. We suggest that surveillance programs must also include monitoring protocols of wildlife; particularly endangered species.

Tobacco smoking is considered to be the key preventable risk factor for morbidity and mortality at the global level. The aim of this study was to determine the prevalence of tobacco smoking and factors associated with the initiation of smoking among university students in Dhaka, Bangladesh. A cross-sectional survey study was conducted with 264 students of Jahangirnagar University, Dhaka, Bangladesh in 2015. A standard, self-administered questionnaire consisting of questions on socio-demographic variables, tobacco smoking status, family and peer tobacco smoking history, attitudes and beliefs about tobacco smoking, as well as knowledge about the negative health consequences of tobacco smoking was administered to participants. Data were analyzed using logistic regression models, chi square, and Fisher exact tests. The overall prevalence of tobacco smoking was 60.2%, where males smoked at higher rates than females (68.81% and 19.56%, respectively). The influence of friends was the most significant reason for initiating tobacco smoking (OR: 0.862; CI: 0.810-0.917). Perception regarding tobacco smoking was significantly related to continuing tobacco use. Logistic regression models identified that smoking-related attitudes, potential health problems, and family members dying from cardiovascular disease and cancer were significantly associated with tobacco smoking. The current tobacco smoking prevalence among university students in Bangladesh is over 60%. We suggest adopting WHO Framework Convention on Tobacco Control (FCTC) policies, especially for university students.

Cervical cancer is one of the leading causes of cancer in women worldwide. One way by which the incidence of this malignant disease can be minimized is by imparting knowledge through health education. This study aimed at developing an educational package on cervical cancer (EPCC) and determining its effectiveness in terms of significant increase in knowledge of rural women regarding cervical cancer. A one group pre-test, post-test design was adopted. Thirty rural women were selected using a convenient sampling method. Data were collected using a demographic questionnaire and a structured knowledge questionnaire developed by the researchers. The EPCC was designed for a duration of one hour and 10 minutes. The structured knowledge questionnaire was first administered as the pre-test, following which knowledge on cervical cancer was imparted using the EPCC. On the 8th day, the post-test was administered. Data were analyzed using descriptive and inferential statistics. The mean post-test knowledge score of the women regarding cervical cancer was significantly higher than that of their mean pre-test score, indicating that the EPCC was effective in improving the knowledge of rural women on cervical cancer. The association between pre-test knowledge scores and selected demo-graphic variables were computed using chi-square test showed that pre-test knowledge score of the women regarding cervical cancer was independent of all the socio-demographic variables. It was concluded that the EPCC is effective in improving the knowledge of women, regarding cervical cancer. Since the prevalence of cervical cancer is high, there is an immediate need to educate women on prevention of cervical cancer.

Cervical cancer is common among women worldwide. A multitude of risk factors aggravate the disease. This study was conducted to: (1) determine the prevalence and (2) make a comparative analysis of the socio-demographic and behavioural risk factors of cervical cancer and knowledge, attitude and practice between rural and urban women of North Bengal, India. Community-based cross-sectional study. A survey (first in North Bengal) was conducted among 133 women in a rural area (Kawakhali) and 88 women in an urban slum (Shaktigarh) using predesigned semi-structured questionnaires. The respondents were informed of the causes (including HPV), signs and symptoms, prevention of cervical cancer and treatment, and the procedure of the PAP test and HPV vaccination. The prevalence of risk factors like multiparity, early age of marriage, use of cloth during menstruation, use of condom and OCP, early age of first intercourse was 37.2%, 82%, 83.3%, 5.4%, 15.8% and 65.6% respectively. Awareness about the cause, signs and symptoms, prevention of cervical cancer, PAP test and HPV vaccination was 3.6%, 6.3%, 3.6%, 9.5% and 14.5% respectively. Chi-square testing revealed that in the study population, significant differential at 5% exists between rural and urban residents with respect to number of children, use of cloth/sanitary napkins, family history of cancer and awareness regarding causes of cervical cancer. Regarding KAP, again using chi-square tests, surprisingly, level of education is found to be significant for each element of KAP in urban areas in contrast to complete absence of association between education and elements of KAP in rural areas. A large number of risk factors were present in both areas, the prevalence being higher in the rural areas. The level of awareness and role of education appears to be insignificant determinants in rural compared to urban areas. This pilot study needs to be followed up by large scale programmes to re-orient awareness campaigns, especially in rural areas.

Burnout is an important problem in health care professionals and is associated with a decrease in occupational well-being and an increase in absenteeism, turnover and illness. Nurses are found to be vulnerable to burnout, but emergency nurses are even more so, since emergency nursing is characterized by unpredictability, overcrowding and continuous confrontation with a broad range of diseases, injuries and traumatic events. This systematic review aims (1) to explore the prevalence of burnout in emergency nurses and (2) to identify specific (individual and work related) determinants of burnout in this population. A systematic review of empirical quantitative studies on burnout in emergency nurses, published in English between 1989 and 2014. The databases NCBI PubMed, Embase, ISI Web of Knowledge, Informa HealthCare, Picarta, Cinahl and Scielo were searched. Seventeen studies were included in this review. On average 26% of the emergency nurses suffered from burnout. Individual factors such as demographic variables, personality characteristics and coping strategies were predictive of burnout. Work related factors such as exposure to traumatic events, job characteristics and organizational variables were also found to be determinants of burnout in this population. Burnout rates in emergency nurses are high. Job demands, job control, social support and exposure to traumatic events are determinants of burnout, as well as several organizational variables. As a consequence specific action targets for hospital management are formulated to prevent turnover and burnout in emergency nurses. Copyright © 2014 Elsevier Ltd. All rights reserved.

To determine the prevalence of cystine uroliths in domestic ferrets with urolithiasis and determine whether age, breed, sex, reproductive status, anatomic location, and season are risk factors associated with cystine urolith formation. Retrospective cross-sectional case-control study. Records of 435 ferrets (Mustela putorius furo) with uroliths submitted for analyses between 1992 and 2009, of which 70 were cystine uroliths. Specific descriptive information was obtained about each ferret to determine whether specific risk factors were associated with the development of cystine uroliths. Cystine uroliths comprised 70 of the 435 (16%) uroliths. Cystine uroliths were more common in male (n = 54) than in female (16) ferrets. All cystine uroliths were retrieved from the lower portion of the urinary tract (bladder and urethra [n = 67]) or were voided (3); none of the uroliths were retrieved from the upper portion of the urinary tract (kidney and ureters). Awareness of the prevalence of cystine uroliths along with knowledge of etiologic, demographic, and environmental risk and protective factors for urolithiasis may facilitate development of surveillance strategies that result in earlier detection of cystinuria. Genetic factors associated with this disease have not yet been reported in ferrets, but a familial pattern of inheritance determined to be a major underlying factor in cystine urolithiasis in dogs and humans suggests that this may be a factor in ferrets and that the parent stock of ferrets in the present study may have been inbred.

With the worldwide increase in the incidence and prevalence of diabetes, there has been an increase in the scope and scale of nursing care and education required for patients with diabetes. The high prevalence of diabetes in Saudi Arabia makes this a particular priority for this country. The aim of this study was to examine nurses' perceived and actual knowledge of diabetes and its care and management in Saudi Arabia. A convenience sample of 423 nurses working in Prince Sultan Medical Military City in Saudi Arabia was surveyed in this descriptive, cross-sectional study. Perceived knowledge was assessed using the Diabetes Self-Report Tool, while the Diabetes Basic Knowledge Tool was used to assess the actual knowledge of participants. The nurses generally had a positive view of their diabetes knowledge, with a mean score (SD) of 46.9 (6.1) (of maximum 60) for the Diabetes Self-Report Tool. Their actual knowledge scores ranged from 2 to 35 with a mean (SD) score of 25.4 (6.2) (of maximum of 49). Nurses' perceived and actual knowledge of diabetes varied according to their demographic and practice details. Perceived competency, current provision of diabetes care, education level and attendance at any diabetes education programs predicted perceived knowledge; these factors, with gender predicted, with actual diabetes knowledge scores. In this multi-ethnic workforce, findings indicated a significant gap between participants' perceived and actual knowledge. Factors predictive of high levels of knowledge provide pointers to ways to improve diabetes knowledge amongst nurses. Crown Copyright © 2017. Published by Elsevier Inc. All rights reserved.

The Joint United Nations Program on HIV/AIDS estimates that between 0.3% and 0.7% of adults aged 15 to 49 years were living with HIV in Ecuador in 2013. However, very little is known about the HIV prevalence rate among men who have sex with men (MSM) in that country. A cross-sectional survey was conducted to investigate the knowledge, attitudes, and practices regarding HIV/AIDS as well as to estimate the prevalence of HIV among MSM in one of the cities with high HIV prevalence rates in Ecuador. In this study, questionnaires were administered to 307 adult MSM. An HIV prevalence of 10% was observed. Knowledge about HIV was high; 91% of participants could identify how HIV is transmitted. Although consistent condom use for anal sex was relatively high (89%) among participants who reported having pay-for-service clients, only 64% reported using a condom during oral sex with a client. Participants who had multiple male sexual partners (i.e., their stable male partners plus other partner[s]) had 3.7 times higher odds of testing positive for HIV compared with those who did not. They also had reduced odds of condom use. Participants who were forced to have anal receptive sex had 3 times higher odds of testing positive for HIV. Despite the finding that participants exhibited high knowledge about HIV/AIDS, a high prevalence rate of HIV was observed, which warrants targeted behavioral interventions. These data are consistent with MSM being one of the highest at-risk population groups for HIV in this region of Ecuador.

Active cigarette smoking is the major cause of lung cancer and an important established cause of cardiovascular disease mortality. Risks have been shown to increase with even light or intermittent active smoking. To assess the prevalence of smoking, age of initiation and the knowledge and attitude towards smoking among dental college students of Rajasthan, India. A cross-sectional study was conducted among 1,383 undergraduate and postgraduate dental college students of Rajasthan using self-administered closed-ended questionnaires consisting of 14 questions divided into four sections. A chi-square test was used to determine the association between dependent and independent variables. Of all the participants, 777 (56.2%) were male and 606 (43.8%) were female. Among these 258 (33.2%) males and 51 (8.4%) females had tried or experimented smoking. Majority of males (24.7%) initiated this habit at a very young age, before 16 years. About 79.5% males and 72.3% females felt that it was difficult to quit smoking. According to 88.1% females and 48.7% males, people feel less comfortable at public places or social gatherings. The study has shown that the smoking prevalence among dental college students is high and has managed to contribute additional information regarding their attitude towards smoking. Comprehensive tobacco education and smoking cessation programmes should be aggressively promoted in dental settings. © 2013 FDI World Dental Federation.

An omnibus telephone survey of 1200 adult Australians determined self-reported prevalence of and attitudes to sunburn and sunspots, knowledge of the term solar keratosis and prevalence of skin checks. Half reported they had been sunburnt in the previous year. Seventy-eight per cent considered sunburn to be extremely or very serious, while 73% considered sunspots as serious or very serious. While 29% reported currently having sunspots, 69% had never heard of the term solar keratosis, 30% had never had a skin check and 28% had their last skin check more than 12 months ago. Respondents 18-29 years old (odds ration [OR] = 2.6; P = 0.002) and men (OR = 2.4; P < 0.001) were most likely to experience multiple sunburn. Persons living in capital cities (OR = 0.63; P = 0.006) and having a university degree (OR = 0.52; P = 0.001) had reduced OR for multiple sunburns. Men (OR = 0.45; P < 0.001) were less likely to consider sunburn serious or extremely serious than women. Compared with respondents 18-29 years old, those 55 years or older were 7.4-fold more likely to have had a skin check (P < 0.001). Sun-protection campaigns need to continue using evidence-based interventions targeting younger people and men to reduce sunburn. The terms used in health promotion need to be understood by the target audience.

Malaria has become one of the major health problems currently facing the urban communities. The rapid increase in urbanization, rural-urban migration and climatic changes are among the main factors contributing for the rise of malaria in urban areas. To our knowledge, there has been no malaria prevalence study so far conducted in Gondar Town. The aim of this study was to determine the prevalence of malaria infection and its associated risk factors in Gondar Town. A community-based survey was conducted in three randomly selected malarious Kebeles of Gondar Town during November-December 2004. Blood films were collected from a finger-prick of 734 members of the selected households for microscopic examination of malaria parasites. Among 734 examined blood films, 39 (5.3%) were positive for malaria infection, of which 29 (74.4%) were due to Plasmodium falciparum and 10 (25.6%) due to P. vivax. Seven (18%) malaria infections were reported from children under the age of five years, indicating the endemicity of malaria to the study area. Age-specific rates show that higher malaria prevalence rate was found among under-five children (7.2%) and 15-19 year-old age group (7.3%). Proximity to mosquito breeding sites was found to be the main risk factor for malaria infection (OR = 2.4, 95% CI. 1.2-5.1). The prevalence of malaria in Gondar Town was found to be high. The prevalence was strongly associated with proximity of residence to potential mosquito breeding sites. The occurrence of the disease among under-five children would indicate that malaria is indigenous to the area. Use of personal protection methods such as insecticide treated mosquito nets should be scaled up, and malaria control interventions should target residents who are at a closer proximity to mosquito breeding sites.

Introduction For obvious reasons, athletes are at greater risk of sustaining a lumber (lower) spine injury due to physical activity. To our knowledge, no previous studies have examined the prevalence of low back pain (LBP) in a Tunisian sports and physical education institute. Aim To assess the prevalence of LBP in different sports among students studying in a sports and physical education institute in Tunisia, to determine the causes of the injuries, and to propose solutions. Methods A total of 3,379 boys and 2,579 girls were studied. A retrospective cross-sectional survey was conducted on a group of students aged 18.5–24.5 years at the Higher Institute of Sport and Physical Education of Sfax to estimate the prevalence of LBP and its relation to the type of sports. Data on age, weight, height, smoking, and the sport in which the student was injured in the low back were collected from the institute health service records from 2005 until 2013. Results LBP was reported by 879 of the 5,958 study participants (14.8%). The prevalence of LBP was significantly higher (p<0.001) in females (17.6%) than in males (12.5%). LBP prevalence did not differ by body mass index or smoking habit (p>0.05). The sports associated with the higher rates of LBP were gymnastics, judo, handball, and volleyball, followed by basketball and athletics. Conclusion LBP is frequent among undergraduate students of a sports and physical education institute in Tunisia. It is strongly associated with fatigue after the long periods of training in different sports. Gymnastics, judo, handball, and volleyball were identified as high-risk sports for causing LBP.

There are gaps in our knowledge of the prevalence of adult atopic dermatitis (AD). To estimate the prevalence of AD in adults and by disease severity. This international, cross-sectional, web-based survey was performed in the United States, Canada, France, Germany, Italy, Spain, United Kingdom, and Japan. Adult members of online respondent panels were sent a questionnaire for AD identification and severity assessment; demographic quotas ensured population representativeness for each country. A diagnosis of AD required subjects to be positive on the modified UK Working Party/ISAAC criteria and self-report of ever having an AD diagnosis by a physician. The proportion of subjects with AD who reported being treated for their condition was determined and also used to estimate prevalence. Severity scales were Patient-Oriented SCORAD, Patient-Orientated Eczema Measure, and Patient Global Assessment. Among participants by region, the point prevalence of adult AD in the overall/treated populations was 4.9%/3.9% in the US, 3.5%/2.6% in Canada, 4.4%/3.5% in the EU, and 2.1%/1.5% in Japan. The prevalence was generally lower for males vs females, and decreased with age. Regional variability was observed within countries. Severity varied by scale and region; however, regardless of the scale or region, proportion of subjects reporting severe disease was lower than mild or moderate disease. Prevalence of adult AD ranged from 2.1% to 4.9% across countries. Severe AD represented a small proportion of the overall AD population regardless of measure or region. © 2018 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Introduction The prevalence, disease progression, and treatment outcomes for patients with type 2 diabetes vary significantly between ethnic groups. The Bihari community constitutes one of the most vulnerable populations in Bangladesh on the basis of access to health services and other fundamental rights. Our study aimed at finding out the prevalence and risk factors of type 2 diabetes among the Bihari adults in Dhaka city. Methods This cross-sectional community-based study was carried out among stranded Pakistanis (known as Bihari) living in camps in the Mirpur area from July 2014 to June 2015. Laboratory-based oral glucose tolerance test (OGTT) was the basis for the diagnosis of type 2 diabetes mellitus (DM). Anthropometric measurements, blood pressure, biochemical tests, family history, and socioeconomic information were obtained to determine the risk factors. Results The prevalence of diabetes mellitus (DM), impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) were estimated at 10.11%, 8.74%, and 4.55%, respectively. Increased diastolic blood pressure, serum triglyceride, and cholesterol level were observed to be significantly (p < 0.05) associated with diabetes. Also, the presence of diabetes, high blood pressure, and obesity among relatives significantly increased the probability of diabetes. Conclusions To the best of our knowledge, this is the first study on diabetes prevalence among the Bihari community in Bangladesh. The prevalence of type 2 diabetes mellitus was found to be higher among the Bihari community compared to the general population in Bangladesh. Health planners and policymakers should realize the alarming situation and identified risk factors and consider the minor ethnic groups during decision-making regarding prevention and control of diabetes and other noncommunicable diseases.

To measure parental awareness of government physical activity guidelines and knowledge of the amount of physical activity recommended for youth (ie, 60 minutes per day, 7 days per week) as specified in the 2008 Physical Activity Guidelines for Americans. A cross-sectional national sample of adults responded to physical activity guideline questions added to the HealthStyles survey in 2009 (n = 1552). The prevalence of parents aware of government physical activity guidelines and knowledgeable of the youth physical activity guideline, specifically, was estimated overall and by parental demographic characteristics (sex, education, income level, race/ethnicity, age group, marital status) and body mass index. In 2009, 34.8% of parents reported being aware of physical activity guidelines, and 9.7% were knowledgeable of the amount of physical activity recommended for youth. Many parents lack awareness and knowledge of the youth physical activity guidelines. The low prevalence estimates suggest the 2008 Physical Activity Guidelines for Americans has not been effectively disseminated. These results may also indicate a need for effective communication strategies to educate and inform parents, an important influencer of children's health behaviors.

Global evidence shows that sexually transmitted infections (STIs) prevalence and sexual risk behaviours are high among youth, and knowledge about STIs is low. In Tanzania, there is limited recent evidence regarding these issues. The aim of this study was to describe the health seeking behaviour of youth reporting STI symptoms in semi-rural Tanzania and to evaluate the association of socio-demographic characteristics, STI knowledge and sexual risk behaviour with STI symptom reporting. This was a cross-sectional study involving 2251 sexually experienced youth (15-24 years), who participated in a larger baseline survey of a cohort within Ifakara town. Interview data were electronically collected by trained field workers. Logistic regression analysis was used to identify factors that influence the risk of reporting STI symptoms within the past year, using Stata 12.1. The prevalence of self-reported STI symptoms in the past year was 19.9%. Almost all of youth had heard of STIs and 32.7% of youth could mention at least one sign. 34.4% had sought care for their STI symptoms, the majority at private facilities. Only 20% of HIV-STI co-infected youth was aware of their HIV status. Youth with more knowledge of STI symptoms reported to have had symptoms more often (OR = 1.28; 95% CI 1.01-1.62), and those reporting having first sex at 16 or under were more likely to report STI symptoms than those who delayed to 17-19 years (OR 1.27; 95% CI 1.003-1.62). These findings highlight the need to improve the implementation of Adolescent Friendly Health Services available in Tanzania (especially in semi-rural areas). The inclusion of private facilities and pharmacies in AFHS scale-up would potentially raise the level of STI knowledge, lower the STI prevalence and reduce HIV incidence among youth.

There is a push to use classroom technology and active teaching methods to replace didactic lectures as the most prevalent format for resident education. This multisite collaborative cohort study involving nine residency programs across the United States compared a standard slide-based didactic lecture, a facilitated group discussion via an engaged classroom, and a high-fidelity, hands-on simulation scenario for teaching the topic of acute dyspnea. The primary outcome was knowledge retention at 2 to 4 weeks. Each teaching method was assigned to three different residency programs in the collaborative according to local resources. Learning objectives were determined by faculty. Pre- and posttest questions were validated and utilized as a measurement of knowledge retention. Each site administered the pretest, taught the topic of acute dyspnea utilizing their assigned method, and administered a posttest 2 to 4 weeks later. Differences between the groups were compared using paired t-tests. A total of 146 residents completed the posttest, and scores increased from baseline across all groups. The average score increased 6% in the standard lecture group (n=47), 11% in the engaged classroom (n=53), and 9% in the simulation group (n=56). The differences in improvement between engaged classroom and simulation were not statistically significant. Compared to standard lecture, both engaged classroom and high-fidelity simulation were associated with a statistically significant improvement in knowledge retention. Knowledge retention after engaged classroom and high-fidelity simulation did not significantly differ. More research is necessary to determine if different teaching methods result in different levels of comfort and skill with actual patient care.

Student nurses are at high risk of blood-borne pathogens transmitted via Needle Stick Injury (NSI). Understanding various aspects of NSI is essential if they are to avoid the risks associated with it. The study was conducted to measure student nurses' level of knowledge about NSI and to examine its prevalence and post-exposure measures in Jordan. A cross-sectional and descriptive design was used. A sample of 279 student nurses studying at one private and four government universities distributed throughout Jordan. The study used an online survey composed of 22 questions developed from NSI literature. The questionnaire was divided into three parts: background, to measure students' demographics; knowledge, to measure nurses' understanding of NSI; and prevalence, to measure exposure to NSI and the follow-up measures. Student nurses were recruited through Facebook. The survey was available online for one full semester in 2016/2017. The total number of completed surveys was 279 (response rate=61%). Most of the students were female (n=198; 71%), in their fourth year (n=114; 40.9%). Their mean age was 21years (SD=2.5). The mean score for the knowledge part was 7 out of 10 (SD=1.7). Almost a third of the students had at least one incident of exposure to NSI (n=73; 26.2%). Most of the students who had suffered NSI did not inform their clinical instructors (67.1%) or write an incident report (86.3%). The results showed that there was no significant difference in the knowledge total scores between males and females or between students across different universities. However, a significant difference was found between students in different years of study (F (276, 2)=6.77, p=0.001). Student nurses in Jordan have a moderate understanding of issues regarding NSI. This knowledge improved with seniority. However, exposure to NSI and its under-reporting is a prevalent problem. This study recommends focusing on NSI in the nursing curriculum, and providing more protection and post-exposure intervention for students during their clinical practice.

Background: Students, clergymen and teachers as role models can be very important in encouragement or prevention of cigarette smoking in young people. The aim of this study was to compare prevalence of smoking in 3 male groups of teachers, clergymen and university students. Also, study their knowledge and attitude towards it and the prediction of their future consumption. Methods: In a cross sectional study in 2009 in Tehran, Iran, 1,271 male students, 549 clergymen and 551 teachers were randomly enrolled. Each participant completed the global adult tobacco survey questionnaire. Knowledge, attitude and prediction of smoking for the next 5 years were questioned in these 3 groups. Chi-squared test and logistic regression were used for analysis. P < 0.05 was considered significant. Results: Prevalence of cigarette smoking was 31.1%, 21.9% and 27.2% among students, clergymen and teachers, respectively. Smoking in students was not associated with poor knowledge but were in teachers and clergymen. The odds ratio of smoking in students, clergymen and teachers was higher among those with having inappropriate attitude towards it (OR = 1.6, 6.1 and 4.5). Those with poor knowledge had an inappropriate attitude and predicted higher chance of cigarette consumption in the next 5 years (P < 0.0001). Inappropriate attitude in all 3 groups resulted in higher prediction of future smoking (P = 0.008). Conclusions: This study revealed that the prevalence of smoking among male students and teachers was higher than general population and clergymen who equally smoked. Also, level of knowledge and attitude of students were lower than teachers and clergymen. PMID:23930167

A project implemented from 2003 to 2005 trained women in Chitwan District, Nepal, in hygienic dairy production using a process of social mobilization. The aim of this research was to assess if the prevalence of mastitis in water buffalo in the households of women who were trained was lower one year after training than in untrained households, if the training influenced knowledge and practices for the prevention or control of mastitis, and if these practices and knowledge were associated with a lower prevalence of mastitis. A total of 202 households from Eastern and Western Chitwan District were included in the study. Of these, 60 households had participated in the project and 142 had not. Milk samples were collected from 129 households (33 project households and 96 non-project households). Clinical mastitis was determined using visual inspection of udders and detection of macroscopic clots and flakes in milk. The California Mastitis Test was used to diagnose sub-clinical mastitis from milk samples, and the IDEXX SNAP test to identify the presence of tetracycline residues. The prevalence of mastitis in trained households (39.4%) was 43.78% of that in untrained households (60.4%), lower but not significantly so (p=0.08, 95% CI 0.17-1.12). Thirteen indicators of knowledge or practice for the control or prevention of mastitis were more likely to occur in trained households, four significantly so (not consuming milk from sick buffalo (p=0.001), using soap to wash hands before milking (p=0.001), discarding milk after antibiotic usage (p=0.01), and choosing appropriate flooring for their livestock (p=0.03)). Trained households that discarded milk from sick buffalo were 2.96 times more likely to have at least one animal with mastitis in the household (p=0.03, 95% CI 1.15-7.65). Trained households that knew to wash buffalos' teats after milking were less likely (OR 0.25) to have mastitis in their herd (p=0.02, 95% CI 0.08-0.80). Of the 138 buffalos tested, only one tested positive for tetracycline residues. 2010 Elsevier B.V. All rights reserved.

Aim: Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada. Materials and Methods: Blood samples from 366 indigenous chickens and 92 commercial chicken layers were collected from all parishes of the island and tested for antibodies against CAstV using commercial enzyme-linked immunosorbent assay. Results: The seroprevalence of antibodies against astrovirus was 57.6% (95%, Confidence interval [CI]: 47.4-67.2) in commercial layers and 61.5% (95%, CI: 56.4-66.3) in indigenous chickens. The results show the presence of infection throughout the island. Conclusion: The results show the infection with CAstV in approximately half of the chicken population in Grenada. This is the first report on the prevalence of CAstV in chickens in Grenada and the Caribbean region. PMID:28717315

Recently, human papilloma virus (HPV) has been implicated to cause several throat and oral cancers and HPV is established to cause most cervical cancers. A human papilloma virus vaccine has been proven successful to reduce infection incidence in FDA clinical trials, and it is currently available in the USA. Current intervention policy targets adolescent females for vaccination; however, the expansion of suggested guidelines may extend to other age groups and males as well. This research takes a first step toward automatically predicting personal beliefs, regarding health intervention, on the spread of disease. Using linguistic or statistical approaches, sentiment analysis determines a text's affective content. Self-reported HPV vaccination beliefs published in web and social media are analyzed for affect polarity and leveraged as knowledge inputs to epidemic models. With this in mind, we have developed a discrete-time model to facilitate predicting impact on the reduction of HPV prevalence due to arbitrary age- and gender-targeted vaccination schemes.

Metabolic syndrome (MS) is a complex disorder defined by a cluster of abdominal obesity, atherogenic dyslipidemia, hyperglycemia, and hypertension; the condition is recognized as a risk factor for diabetes and cardiovascular disease. This study assessed the effects of the Sasang constitution group (SCG) on the risk of MS in Korean subjects. We have analyzed 1,617 outpatients of Korean oriental medicine hospitals who were classified into three SCGs, So-Yang, So-Eum, and Tae-Eum. Significant differences were noted in the prevalence of MS and the frequencies of all MS risk factors among the three SCGs. The odds ratios for MS as determined via multiple logistic regression analysis were 2.004 for So-Yang and 4.521 for Tae-Eum compared with So-Eum. These results indicate that SCG may function as a significant risk factor of MS; comprehensive knowledge of Sasang constitutional medicine may prove helpful in predicting susceptibility and developing preventive care techniques for MS.

Giardia duodenalis is one of the most prevalent enteroparasites in children. This parasite produces several clinical manifestations. The aim of this study was to determine the prevalence of genotypes of G. duodenalis causing infection in a region of southeastern Mexico. G. duodenalis cysts were isolated (33/429) from stool samples of children and molecular genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis, targeting the triosephosphate isomerase ( tpi ) and glutamate dehydrogenase ( gdh ) genes. The tpi gene was amplified in all of the cyst samples, either for assemblage A (27 samples) or assemblage B (6 samples). RFLP analysis classified the 27 tpi -A amplicons in assemblage A, subgenotype I. Samples classified as assemblage B were further analysed using PCR-RFLP of the gdh gene and identified as assemblage B, subgenotype III. To our knowledge, this is the first report of assemblage B of G. duodenalis in human clinical samples from Mexico. PMID:24676655

Sexual behavior during travel has increasingly become a focus of travel medicine research. The perceived freedom when away from home can lead to increased casual sexual activities, often unprotected. Local sexual partners, particularly those who are in close contact with tourists due to their occupation, need to be considered more in research. The purpose of this study was to explore the sexual behavior, knowledge of STI prevention, and prevalence of serum markers of selected STIs in tour guides in Cuzco/Peru. In this cross-sectional study, 161 tour guides completed a questionnaire consisting of information on demographics, sexual behavior, and knowledge about STI prevention. Blood samples of the participants were tested for antibodies against HSV2, Chlamydia trachomatis, and Treponema pallidum using commercial enzyme-linked immunosorbent assay kits. The majority of guides (65%) were sexually active during the year prior to the study and 10% had foreign partners. Consistent condom use was reported by 38.1%, but almost 42% did not use condoms. In total, 27.6% reported symptoms compatible with STI. Three quarters of the participants had previously received information on STI prevention, predominantly from health professionals. In total, 22% considered themselves at high risk for STI. Antibodies against C trachomatis were prevalent in 15%, while 88.2% were against HSV2. None had antibodies against T pallidum. There is an inconsistency in reported sexual behavior and reported knowledge about STI prevention. Because of the tour guides' bridging position between potential STI carriers in tourists and the local population, the reported nonuse of condoms is of concern. The prevalence of serum markers supports this concern, which is aggravated by the potential of noncurable infections. Current sexual health education strategies seem unsatisfactory, and major modifications are highly recommended.

A high prevalence of dental trauma exists and its effects on function and esthetics deserve the attention of general dentists. The aim of this study was to assess the level of general dental practitioners' (GDPs) knowledge about guidelines for dental avulsion and its prevention using a questionnaire. The 21-item questionnaire was distributed among 264 GDPs and the survey was realized between August-November 2006. The data obtained were statistically analyzed using descriptive analysis and Pearson's Chi-square test to determine associations between knowledge regarding emergency treatment and dentists from public or private dental schools and years of experience. The results showed that the participants exhibited appropriate knowledge concerning procedures in cases of tooth avulsion and its prevention. The number of correct answers was low in relation to recommended treatment at the site of injury. Storage medium, preparation of the alveolus and splint time for receiving the avulsed tooth received a high number of correct answers. One statistically significant association between years of experience and recommended treatment at the site of the injury in the case an avulsed tooth (chi(2) = 9.384, P = 0.009). In conclusion, this survey showed appropriate knowledge of dental avulsion management and its prevention among the surveyed dentists. The findings also showed that communication between dentists and the population is deficient, especially concerning practitioners of high risk and contact sports.

Senior nurses' control expectations and the development of pressure ulcers.

PubMed

Maylor, M

The aim of this research was to establish whether the attitudes and expectations of senior nursing staff might adversely affect patient outcomes in the prevention of pressure ulcers. The hypothesis was that nursing locus of control affects clinical outcomes in patients. In particular, it affects departmental prevalence of pressure damage. A population of nurses (n = 439) in an acute and community NHS trust were surveyed to test knowledge, control beliefs and value of pressure ulcer prevention relative to prevalence. The research was designed to provide different data against which to test the hypothesis: first, to assess acceptability of nurses' knowledge of prevention and appropriate use of risk assessment and equipment; second, to calculate a mean departmental pressure ulcer prevalence; and third, to measure locus of control and value, which is the focus of this article. There were strong associations between departmental prevalence of pressure ulcers and attitudes of senior nursing staff. For example, the more that ward sisters believed they could control pressure ulcer prevention, the higher the prevalence of ulcers in their department. The more that sisters believed that they could not control prevalence, the lower the prevalence of ulcers. The study shows that failure to account for beliefs, values and expectations of staff could lead to patient harm. It is suggested that it might be counterproductive to put great effort into developing clinical guidelines and refinement of risk assessment methods. The findings have important implications for nursing, and challenge the assumption that nurse leaders are universally beneficial to patients.

Nosocomial infections due to Klebsiella pneumoniae is a significant problem in health care settings worldwide. In this study, we examined the antimicrobial susceptibility, genetic profiles and mechanisms of antibiotic resistance in K. pneumoniae isolates of Indian origin. To our knowledge this is the first report demonstrating the high prevalence of β-lactamases, aminoglycoside modifying enzymes, quinolone resistance genes besides demonstrating the involvement of active efflux in K. pneumoniae Indian isolates. This study has enabled us to correlate the phenotypic and genotypic characteristics in K. pneumoniae, providing an important base for continued monitoring and epidemiological studies of this emerging nosocomial pathogen in Indian hospitals.

To determine physicians' knowledge, awareness and preferences regarding the care of familial hypercholesterolaemia (FH) in the Asia-Pacific region. A formal questionnaire was anonymously completed by physicians from different countries/regions in the Asia-Pacific. The survey sought responses relating to general familiarity, awareness of management guidelines, identification (clinical characteristics and lipid profile), prevalence and inheritance, extent of elevation in risk of cardiovascular disease (CVD) and practice on screening and treatment. Practising community physicians from Australia, Japan, Malaysia, South Korea, Philippines, Hong Kong, China, Vietnam and Taiwan were recruited to complete the questionnaire, with the UK as the international benchmark. An assessment and comparison of the knowledge, awareness and preferences of FH among physicians in 10 different countries/regions. 1078 physicians completed the questionnaire from the Asia-Pacific region; only 34% considered themselves to be familiar with FH. 72% correctly described FH and 65% identified the typical lipid profile, with a higher proportion of physicians from Japan and China selecting the correct FH definition and lipid profile compared with those from Vietnam and Philippines. However, less than half of the physician were aware of national or international management guidelines; this was significantly worse than physicians from the UK (35% vs 61%, p<0.001). Knowledge of prevalence (24%), inheritability (41%) and CVD risk (9%) of FH were also suboptimal. The majority of the physicians considered laboratory interpretative commenting as being useful (81%) and statin therapy as an appropriate cholesterol-lowering therapy (89%) for FH management. The study identified important gaps, which are readily addressable, in the awareness and knowledge of FH among physicians in the region. Implementation of country-specific guidelines and extensive work in FH education and awareness programmes are imperative to improve the care of FH in the region. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2016-08-01

Within the European activities for the 'Monitoring and Collection of Information on Zoonoses', annually EFSA publishes a European report, including information related to the prevalence of Campylobacter spp. in Germany. Spatial epidemiology becomes here a fundamental tool for the generation of these reports, including the representation of prevalence as an essential element. Until now, choropleth maps are the default visualization technique applied in epidemiological monitoring and surveillance reports made by EFSA and German authorities. However, due to its limitations, it seems to be reasonable to explore alternative chart type. Four maps including choropleth, cartogram, graduated symbols and dot-density maps were created to visualize real-world sample data on the prevalence of Campylobacter spp. in raw chicken meat samples in Germany in 2011. In addition, adjacent and coincident maps were created to visualize also the associated uncertainty. As an outcome, we found that there is not a single data visualization technique that encompasses all the necessary features to visualize prevalence data alone or prevalence data together with their associated uncertainty. All the visualization techniques contemplated in this study demonstrated to have both advantages and disadvantages. To determine which visualization technique should be used for future reports, we recommend to create a dialogue between end-users and epidemiologists on the basis of sample data and charts. The final decision should also consider the knowledge and experience of end-users as well as the specific objective to be achieved with the charts. © 2015 The Authors.

Slocum, Sarah; Holroyd, Suzanne

2016-08-01

Conversion disorder (CD) is believed to be the manifestation of physical and/or neurological symptoms for primary gain without an identifiable organic cause. Although it is believed to be more common in rural areas, the literature examining this claim is sparse. To our knowledge, no study has been published evaluating the prevalence of CD in a rural Appalachian population. The aim of this study was to characterize and determine the prevalence of CD per Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, criteria in a rural Appalachian psychiatric consultation service and to compare this population with control patients from the same service. We performed a retrospective chart review of all patients diagnosed as having CD per Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, criteria on a psychiatric consultation service at a rural Appalachian academic medical center during a 13-month time period. For each case, two consecutive control patients were selected from the same service and time span. There were 21 cases and 42 controls in this study, with a CD prevalence rate of 6.0% (N = 21/351). Sociodemographic, comorbidity, and recent symptomatology data were obtained. Compared with controls, cases were significantly younger and were more likely to have a history of sexual abuse, seizure disorder, antiepileptic use, neurologic referral, electroencephalogram, magnetic resonance imaging of the brain, and history of CD. We found it interesting that fewer cases reported alcohol and drug use. The observed prevalence of 6.0% does not support the historical theory that CD is more prevalent in rural or lower socioeconomic populations. Our data add to the characterization of the Appalachian CD population.

Background The Middle East region has one the highest prevalence rates of diabetes in the world. Little is known about the determinants of adherence and the role of knowledge in diabetes self-management within these populations. Objective To investigate the relationship between patients knowledge of diabetes therapeutic targets with adherence to self-care measures in a sample of patients with type 2 diabetes in Kuwait. Setting Primary care chronic care clinics within the Ministry of Health of Kuwait. Methods A cross sectional survey was carried out with 238 patients from six clinics. A multistage stratified clustered sampling method was used to first randomly select the clinics and the patients. Self-reported adherence to three behaviours: medication taking, diet and physical activity. Results Respondents were able to correctly report a mean (SD) of 1.6 (1.3) out of 5 of the pre-specified treatment targets. Optimal adherence to physical activity, diet and medications was reported in 25, 33 and 47 % of the study cohort, respectively. A structural equation model analysis showed better knowledge of therapeutic goals and own current levels translated into better adherence to medications, diet and physical activity. Conclusion Knowledge of therapeutic goals and own recent levels is associated with adherence to medications, diet, or physical activity in this Kuwaiti cohort of patients with diabetes. Low adherence to self-care management and poor overall knowledge of diabetes is a big challenge to successful diabetes care in Kuwait.

The burden of undernutrition in South Asia is greater than anywhere else. Policies and programmatic efforts increasingly address health and non-health determinants of undernutrition. In Nepal, one large-scale integrated nutrition program, Suaahara, aimed to reduce undernutrition among women and children in the 1,000-day period, while simultaneously addressing inequities. In this study, we use household-level process evaluation data (N = 480) to assess levels of exposure to program inputs and levels of knowledge and practices related to health, nutrition, and water, sanitation, and hygiene (WASH). We also assess Suaahara's effect on the differences between disadvantaged (DAG) and non-disadvantaged households in exposure, knowledge, and practice indicators. All regression models were adjusted for potential confounders at the child-, maternal-, and household levels, as well as clustering. We found a higher prevalence of almost all exposure and knowledge indicators and some practice indicators in Suaahara areas versus comparison areas. A higher proportion of DAG households in Suaahara areas reported exposure, were knowledgeable, and practiced optimal behaviors related to nearly all maternal and child health, nutrition, and WASH indicators than DAG households in non-Suaahara areas and sometimes even than non-DAG households in Suaahara areas. Moreover, differences in some of these indicators between DAG and non-DAG households were significantly smaller in Suaahara areas than in comparison areas. These results indicate that large-scale integrated interventions can influence nutrition-related knowledge and practices, while simultaneously reducing inequities. © 2017 John Wiley & Sons Ltd.

Objective In China, policy and social taboo prevent unmarried adolescents from accessing sexual and reproductive health (SRH) services. Research is needed to determine the SRH needs of highly disadvantaged groups, such as adolescent female sex workers (FSWs). This study describes SRH knowledge, contraception use, pregnancy, and factors associated with unmet need for modern contraception among adolescent FSWs in Kunming, China. Methods A cross-sectional study using a one-stage cluster sampling method was employed to recruit adolescents aged 15 to 20 years, and who self-reported having received money or gifts in exchange for sex in the past 6 months. A semi-structured questionnaire was administered by trained peer educators or health workers. Multivariable logistic regression was conducted to determine correlates of low knowledge and unmet need for modern contraception. Results SRH knowledge was poor among the 310 adolescents surveyed; only 39% had heard of any long-acting reversible contraception (implant, injection or IUD). Despite 98% reporting not wanting to get pregnant, just 43% reported consistent condom use and 28% currently used another form of modern contraception. Unmet need for modern contraception was found in 35% of adolescents, and was associated with having a current non-paying partner, regular alcohol use, and having poorer SRH knowledge. Past abortion was common (136, 44%). In the past year, 76% had reported a contraception consultation but only 27% reported ever receiving SRH information from a health service. Conclusions This study demonstrated a low level of SRH knowledge, a high unmet need for modern contraception and a high prevalence of unintended pregnancy among adolescent FSWs in Kunming. Most girls relied on condoms, emergency contraception, or traditional methods, putting them at risk of unwanted pregnancy. This study identifies an urgent need for Chinese adolescent FSWs to be able to access quality SRH information and effective modern contraception. PMID:25625194

Prevalence of autism spectrum disorders--autism and developmental disabilities monitoring network, six sites, United States, 2000.

2007-02-09

Data from a population-based, multisite surveillance network were used to determine the prevalence of children aged 8 years with autism spectrum disorder (ASD) in six areas of the United States and to describe the characteristics of these children. 2000. Children aged 8 years were identified as having an ASD through screening and abstraction of evaluation records at multiple sources, with clinician review of abstracted records to determine case status. Children whose parent(s) or legal guardian(s) resided in one of the six surveillance areas during 2000 and whose records documented behaviors consistent with the American Psychiatric Association's criteria for diagnosing 1) autistic disorder, 2) pervasive developmental disorder-not otherwise specified, or 3) Asperger disorder were classified as having an ASD. For 2000, across six sites, a total of 1,252 children aged 8 years were identified as having an ASD. The overall prevalence of ASDs per 1,000 children aged 8 years ranged from 4.5 in West Virginia to 9.9 in New Jersey. With the exception of one surveillance site (Georgia), no statistically significant (p<0.05) differences were identified in the rate of ASDs between non-Hispanic black and non-Hispanic white children. The ratio of male-to-female prevalence varied (range: 2.8:1.0-5.5:1.0). The majority of children with ASDs received special education services and had a documented history of concerns regarding their development before age 3 years. The prevalence of children with a previously documented ASD classification varied across sites, but the median age of earliest documented ASD diagnosis was similar across sites (age 52-56 months). For three sites with sufficient data on intelligence quotient (IQ), cognitive impairment (i.e., IQ of

Human papillomaviruses (HPVs) remain a serious world health problem due to their association with cervical and head and neck cancers. While over 100 HPV types have been identified, only a few subtypes are associated with malignancies. HPV 16 and 18 are the most prevalent oncogenic types in head and neck cancers. Although it has been proven that some subsets of benign and malignant head and neck lesions are associated with HPV, the general population have very little awareness and knowledge of their association with HPV. Therefore, the purpose of this study was to determine the knowledge of HPV and its links with head and neck benign and malignant lesions in a group of Pakistani dental patients who attended the Dental Department of the Sandeman provincial hospital in Quetta, Pakistan. One hundred and ninety-two patients were recruited and requested to answer a questionnaire. It was revealed that there was a low level of knowledge about HPV and its association with head and neck benign and malignant lesions among the participants. This result suggested that more education regarding the relationship of HPV in inducing head and neck benign and malignant lesions is required in this group of patients.

As recent events attest, sexual harassment is an important yet misunderstood problem. Because it has only recently been recognized as a significant issue, research on sexual harassment is somewhat limited. Knowledge of the prevalence and effects on sexual harassment on campus is necessary to ensure that all people have access to a safe and…

Knowledge of the prevalence and risk factors associated with maternal infection is the first step to develop a surveillance system for congenital transmission of Chagas disease. We conducted a cross-sectional study in Casanare, a disease-endemic area in Colombia. A total of 982 patients were enrolled in the study. A global prevalence of Trypanosoma cruzi infection of 4.0% (95% confidence interval [CI] = 2.8–5.3%) was found. Multivariate analysis showed that the most important risk-associated factors were age > 29 years (adjusted odds ratio [aOR] = 3.4, 95% CI = 0.9–12.4), rural residency (aOR = 2.2, 95% CI = 1.0–4.6), low education level (aOR = 10.2, 95% CI = 1.6–82.7), and previous knowledge of the vector (aOR = 2.2, 95% CI = 1.0–4.9). Relatives and siblings of infected mothers showed a prevalence of 9.3%. These findings may help physicians to investigate congenital cases, screen Chagas disease in siblings and relatives, and provide early treatment to prevent the chronic complications of Chagas disease.

Present study was aimed to investigate the prevalence and knowledge about different aspects of somnambulism in general population of Buner District, KP, Pakistan, during December 2015-November 2016. Data was collected through convenient sampling technique which was comprised of structured and detailed questionnaire. Collected data regarding different actions performed by sleepwalkers were adjusted through a weighted variable to generalize results. Univariate and multivariate logistic regression was used to evaluate association between variables related to somnambulism. Their odds ratios (ORs) were reported with their corresponding 95% CIs. In total, 11,881 individuals were surveyed, of which 448 (4%) suffered with sleep disorder. Females 256/448 (57%) were more prevalent as compared to males 192/448 (43%). Prevalence of somnambulism among children was 38% whereas 94% sufferers reported no effect on their growth. Majority of respondents reported that main cause of sleepwalking is stress and tension. Somnambulism was taken normal and mostly amusing disorder by sufferers and their families. Sleepwalking is not age specific and serious disorder. Sleepwalkers need special care during their episode due to unconsciousness.

To assess the association between human immunodeficiency virus (HIV) and pregnancy intentions and safer conception knowledge among female sex workers in Port Elizabeth, South Africa. This cross-sectional study recruited female sex workers in Port Elizabeth using respondent-driven sampling and completed an interviewer-administered questionnaire alongside HIV testing and counseling. In this secondary analysis, robust Poisson regression was used to model prevalence ratios for positive fertility intentions in this cross-sectional study. Knowledge of safer conception methods by HIV status was compared using Fisher exact tests. Overall 391 women were represented in the analyses. More than 50% had a prior HIV diagnosis, and an additional 12% were diagnosed with HIV during the study. Approximately half (n=185) of the women reported future pregnancy intentions. In univariate analysis, a prior HIV diagnosis was negatively associated with pregnancy intentions as compared with HIV-negative women (prevalence ratio 0.68, 95% confidence interval 0.55-0.85). Only parity remained independently associated with future pregnancy intentions in multivariate regression after controlling for HIV status, age, race, relationship status, and years selling sex. Knowledge of safer conception methods such as timed sex without a condom, preexposure prophylaxis, or self-insemination was low and similar between those with and without future pregnancy plans. Pregnancy intentions did not significantly vary according to HIV status. Fertility intentions were high, however, and knowledge of safer conception methods low, suggesting a need to provide female sex workers with advice around options to conceive safely in the context of high HIV prevalence.

Knowledge and Attitude of Nursing Students toward Electroconvulsive Therapy

Sharma, Nitasha; Ghai, Sandhya; Grover, Sandeep

2017-01-01

Background: Electroconvulsive therapy (ECT) is one of the commonly used treatment modalities for patients with severe mental disorders. However, acceptance of ECT by the patient and relatives often depends on how the health-care professionals themselves present the treatment modality to the patients and their relatives. There is a lack of information about the knowledge and attitude toward ECT among health professionals. Aim: This study aimed to evaluate the knowledge about and attitude toward ECT among nursing students. Methodology: Knowledge of and attitudes toward ECT among nursing students were assessed using ECT knowledge and attitude questionnaires. Results: The study included 183 nursing students. Majority (n = 62; 60.8%) of the participants obtained information about ECT from media (movies, television, print media, etc.). None of the students had full knowledge about ECT. Although a significant proportion of students had knowledge about the ECT procedure and consent procedure, majority of them had poor knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitudes were also highly prevalent, with more than two-thirds of the participants having negative attitudes toward ECT on more than half of the attitude items of the scale. Total knowledge score positively correlated with total attitude score, suggesting that higher knowledge was associated with more positive attitude. Conclusions: Although nursing students have knowledge about basic ECT procedure and consent, they lack knowledge about the effectiveness, mechanism of action, indications, and side effects of ECT. Negative attitude toward ECT is also highly prevalent among nursing students. Accordingly, there is a need to improve the knowledge and address the negative attitude of nursing students, which may ultimately lead to better acceptance of the treatment. PMID:28936064

Background Food allergy prevalence is increasing in US children. Presently, the primary means of preventing potentially fatal reactions are avoidance of allergens, prompt recognition of food allergy reactions, and knowledge about food allergy reaction treatments. Focus groups were held as a preliminary step in the development of validated survey instruments to assess food allergy knowledge, attitudes, and beliefs of parents, physicians, and the general public. Methods Eight focus groups were conducted between January and July of 2006 in the Chicago area with parents of children with food allergy (3 groups), physicians (3 groups), and the general public (2 groups). A constant comparative method was used to identify the emerging themes which were then grouped into key domains of food allergy knowledge, attitudes, and beliefs. Results Parents of children with food allergy had solid fundamental knowledge but had concerns about primary care physicians' knowledge of food allergy, diagnostic approaches, and treatment practices. The considerable impact of children's food allergies on familial quality of life was articulated. Physicians had good basic knowledge of food allergy but differed in their approach to diagnosis and advice about starting solids and breastfeeding. The general public had wide variation in knowledge about food allergy with many misconceptions of key concepts related to prevalence, definition, and triggers of food allergy. Conclusion Appreciable food allergy knowledge gaps exist, especially among physicians and the general public. The quality of life for children with food allergy and their families is significantly affected. PMID:18803842

Most U.S. clinical trials are funded by industry. Opportunities exist for sponsors to influence research in ways that jeopardize research objectivity. The purpose of this study was to survey U.S. medical school faculty to assess financial arrangements between investigators and industry to learn about investigators’ first hand knowledge of the effects of industry sponsorship on research. Here we show first-hand knowledge that compromises occurred in: research participants’ well-being (9%), research initiatives (35%), publication of results (28%), interpretation of research data (25%), and scientific advancement (20%) because of industry support. Financial relationships with industry were prevalent and considered important to conducting respondents’ research. PMID:19353387

Borsheski, Robert; Johnson, Quinn L

2014-01-01

Pain is a highly prevalent and clinically important problem in the elderly. Unfortunately, due to difficulties in assessing pain in geriatric patients, the complexities of multiple comorbidities, and the high prevalence of polypharmacy, many practitioners are reluctant to treat pain aggressively in this unique patient population. Safe and effective treatment therefore, requires a working knowledge of the physiologic changes associated with aging, the challenges of accurately assessing pain, the unique effects of common therapeutic agents upon the elderly as well as the importance of adjunctive therapies. The following review is intended to provide the practitioner with practical knowledge for safer and more effective treatment of pain.

2012-03-01

Heterosexual transmission of HIV through contact with female sex workers (FSWs) is a growing concern for the HIV/AIDS epidemic in China. Using consecutive cross-sectional surveys, we examined the prevalence of HIV and sexually transmitted infections (STIs), risk behaviours, HIV knowledge and the utilization of intervention services among FSWs in Shandong Province. Of 3460 participants, half reported ever having STI-related symptoms, 57.8% had ≥7 clients in the last week, half reported inconsistent use of condoms with clients and 11.2% reported ever using illicit drugs. Consistent use of condoms with clients was associated with higher education, being 20-24 years of age, being recruited from hotels, having ever received free condoms and was inversely associated with STI-related symptoms. HIV-related knowledge was associated with higher education, ever testing for HIV and inversely associated with self-reported STI-related symptoms. The low rates of condom use, high number and frequent turnover of clients, high prevalence of self-reported STIs and drug use highlight the urgency for more effective intervention in these FSWs.

How does domain-specific knowledge influence the experts' performance in their domain of expertise? Specifically, can visual search experts find, with uniform efficiency, any type of target in their domain of expertise? We examined whether acquired knowledge of target importance influences an expert's visual search performance. In some professional searches (e.g., medical screenings), certain targets are rare; one aim of this study was to examine the extent to which experts miss such targets in their searches. In one experiment, radiologists (medical experts) engaged in a medical lesion search task in which both the importance (i.e., seriousness/gravity) and the prevalence of targets varied. Results showed decreased target detection rates in the low prevalence conditions (i.e., the prevalence effect). Also, experts were better at detecting important (versus unimportant) lesions. Results of an experiment using novices ruled out the possibility that decreased performance with unimportant targets was due to low target noticeability/visibility. Overall, the findings suggest that radiologists do not have a generalized ability to detect any type of lesion; instead, they have acquired a specialized ability to detect only those important lesions relevant for effective medical practices.

The purpose of this study was to evaluate the rate of detection of coagulase negative staphylococci (CoNS) in environmental samples of 17 services in a Tunisian hospital, determining the antimicrobial resistance phenotypes and genotypes of recovered isolates. To our knowledge, this is the first study that determines the prevalence of CoNS with correlation of antibiotic resistance in the hospital environment in Tunisia. CoNS were obtained from 83 of the 200 tested samples (41.5%). Staphylococcus haemolyticus was the most prevalent species (45.8%), followed by S. saprophyticus (36.1%). The remaining CoNS species detected were S. epidermidis, S. cohnii, S. warneri, S. sciuri, S. simulans, S. pasteuri, S. arlettae, and S. xilosus. Methicillin-resistant CoNS were detected in 20 of the 200 tested samples (10%), and the mecA gene was demonstrated in 18 S. haemolyticus, one S. epidermidis and one S. saprophyticus isolates. Methicillin susceptible isolates were detected in 63 samples (31.5%). Antimicrobial resistance genes detected were as follows (number of isolates): erythromycin [msr(A) (n = 32); erm(C) (n = 8)], tetracycline [tet(K) and/or tet(M) (n = 21)], gentamicin [aac(6')-Ie-aph(2″)-Ia (n = 16)], kanamycin [(aph(3')-IIIa (n = 19)], tobramycin [ant(4')-Ia (n = 14)], and streptomycin [ant(6')-Ia (n = 3)]. The high frequency of detection of multi-drug-resistant CoNS in the hospital environment, especially S. haemolyticus and S. saprophyticus, is of relevance and could be due to cross-transmission between patients, staff, and environment.

Tobacco use is one of the leading and preventable causes of global morbidities and premature mortalities. The study explores gender differences in the prevalence and determinants of tobacco use among school-aged adolescents (11-17 years) in Sudan and South Sudan. The study utilized the national Global Youth Tobacco Survey (GYTS) data collected in 2005 for Sudan (4,277 unweighted; 131,631 weighted). Univariate and bivariate analyses were conducted to examine the associations between the dependent (tobacco use status) and independent variables. Logistic regression analyses were performed to identify the key factors which influence tobacco consumption among adolescents in the 2 Sudans for ever cigarette users, current cigarette users, and users of noncigarette tobacco products. There were significant gender differences in the prevalence of ever cigarette users (21.8%; male=13.1%, female=6.5%, p<0.05) and current cigarette users (6.9%; male=4.9%, female = 1.3%, p<0.05) but not among users of noncigarette tobacco products (14.7%; male=6.8%, female=6.1%). Adolescent tobacco use was significantly associated with availability of monthly income or allowance, exposure to tobacco industry promotions, and tobacco-use behavior of familial relations. Knowledge about the harmful effects of secondhand smoke was related with decreased likelihood of tobacco use. School programs that focus on health messages alone may not work for the adolescent population. Legislations that ban all types of tobacco advertisements, promotions, and sponsorships among adolescents are needed in the 2 countries.

There is a dearth of research examining the health correlates of tobacco use within the homeless population, particularly with respect to homeless Veterans. An aim of the present study was to compare homeless Veteran and homeless non-Veteran smokers across a series of socio-demographic and health variables, and to determine whether any of these variables were independently associated with Veteran status. A subsequent aim was to compare the socio-demographic and health profiles of Veteran smokers and Veteran nonsmokers, and to determine whether any of these variables were independently associated with current smoking. Data were obtained from the 2009 Homelessness in Minnesota survey conducted by the Wilder Research Foundation. The final sample included 4750 homeless individuals living throughout Minnesota. The prevalence of smoking was greater among homeless Veterans (74%) than homeless non-Veterans (70%). The prevalence of physical and mental health problems was higher among homeless Veteran smokers than homeless non-Veteran smokers, although these variables were not independently associated with Veteran status after controlling for socio-demographics. Analyses of the homeless Veteran sample indicated that receipt of Veterans' benefits, type of discharge, and alcohol and/or chemical dependence were independently associated with current smoking. Homeless Veteran smokers exhibit heightened rates of physical and mental health problems compared to homeless non-Veteran smokers. Military service and discharge characteristics may contribute to this high smoking prevalence. Future efforts should focus on increasing Veterans' access to and knowledge of Veterans' health resources, and on developing innovative strategies to boost cessation in this population.

2016-01-01

Introduction: Transgender populations have been underrepresented in HIV epidemiologic studies and consequently in HIV prevention, care, and treatment programs. Since 2012, there has been a dramatic increase in research focused on transgender people. Studies highlight the burden of HIV and risk determinants, including intersecting stigmas, as drivers of syndemics among transgender populations. This review synthesizes the most recent global epidemiology of HIV infection and describes current gaps in research and interventions to inform prioritization of HIV research for transgender populations. Methods: A systematic review was conducted of the medical literature published between January 1, 2012 and November 30, 2015. The data focused on HIV prevalence, determinants of risk, and syndemics among transgender populations. Results: Estimates varied dramatically by location and subpopulation. Transfeminine individuals have some of the highest concentrated HIV epidemics in the world with laboratory-confirmed prevalence up to 40%. Data were sparse among trans masculine individuals; however, they suggest potential increased risk for trans masculine men who have sex with men (MSM). No prevalence data were available for transgender people across Sub-Saharan Africa or Eastern Europe/Central Asia. Emerging data consistently support the association of syndemic conditions with HIV risk in transgender populations. Discussion: Addressing syndemic conditions and gender-specific challenges is critical to ensure engagement and retention in HIV prevention by transgender populations. Future research should prioritize: filling knowledge gaps in HIV epidemiology; elucidating how stigma shapes syndemic factors to produce HIV and other deleterious effects on transgender health; and understanding how to effectively implement HIV interventions for transgender people.

Background: Transmission of Mycobacterium tuberculosis (M. tuberculosis) can occur in different ways. Furthermore, drug resistant in M. tuberculosis family is a major problem that creates obstacles in treatment and control of tuberculosis (TB) in the world. One of the most prevalent families of M. tuberculosis is Haarlem, and it is associated with drug resistant. Our objectives of this study were to determine the prevalence and occurrence rate of M. tuberculosis Haarlem family multi-drug resistant (MDR) in the worldwide using meta-analysis based on a systematic review that performed on published articles. Materials and Methods: Data sources of this study were 78 original articles (2002-2012) that were published in the literatures in several databases including PubMed, Science Direct, Google Scholar, Biological abstracts, ISI web of knowledge and IranMedex. The articles were systematically reviewed for prevalence and rate of MDR. Data were analyzed using meta-analysis and random effects models with the software package Meta R, Version 2.13 (P < 0.10). Results: Final analysis included 28601 persons in 78 articles. The highest and lowest occurrence rate of Haarlem family in M. tuberculosis was in Hungary in 2006 (66.20%) with negative MDR-TB and in China in 2010 (0.8%), respectively. From 2002 to 2012, the lowest rate of prevalence was in 2010, and the highest prevalence rate was in 2012. Also 1.076% were positive for MDR and 9.22% were negative (confidence interval: 95%).0020. Conclusion: Many articles and studies are performed in this field globally, and we only chose some of them. Further studies are needed to be done in this field. Our study showed that M. tuberculosis Haarlem family is prevalent in European countries. According to the presence of MDR that was seen in our results, effective control programs are needed to control the spread of drug-resistant strains, especially Haarlem family. PMID:25767526

Escherichia coli O157 (EcO157) infection has been recognized as an important global public health concern. But information on the prevalence of EcO157 in cattle at the global and at the wider geographical levels is limited, if not absent. This is the first meta-analysis to investigate the point prevalence of EcO157 in cattle at the global level and to explore the factors contributing to variation in prevalence estimates. Seven electronic databases- CAB Abstracts, PubMed, Biosis Citation Index, Medline, Web of Knowledge, Scirus and Scopus were searched for relevant publications from 1980 to 2012. A random effect meta-analysis model was used to produce the pooled estimates. The potential sources of between study heterogeneity were identified using meta-regression. A total of 140 studies consisting 220,427 cattle were included in the meta-analysis. The prevalence estimate of EcO157 in cattle at the global level was 5.68% (95% CI, 5.16-6.20). The random effects pooled prevalence estimates in Africa, Northern America, Oceania, Europe, Asia and Latin America-Caribbean were 31.20% (95% CI, 12.35-50.04), 7.35% (95% CI, 6.44-8.26), 6.85% (95% CI, 2.41-11.29), 5.15% (95% CI, 4.21-6.09), 4.69% (95% CI, 3.05-6.33) and 1.65% (95% CI, 0.77-2.53), respectively. Between studies heterogeneity was evidenced in most regions. World region (p<0.001), type of cattle (p<0.001) and to some extent, specimens (p = 0.074) as well as method of pre-enrichment (p = 0.110), were identified as factors for variation in the prevalence estimates of EcO157 in cattle. The prevalence of the organism seems to be higher in the African and Northern American regions. The important factors that might have influence in the estimates of EcO157 are type of cattle and kind of screening specimen. Their roles need to be determined and they should be properly handled in any survey to estimate the true prevalence of EcO157.

Background: Comorbidity is an area of increasing interest in multiple sclerosis (MS). Objective: The objective of this review is to estimate the incidence and prevalence of comorbidity in people with MS and assess the quality of included studies. Methods: We searched the PubMed, SCOPUS, EMBASE and Web of Knowledge databases, conference proceedings, and reference lists of retrieved articles. Two reviewers independently screened abstracts. One reviewer abstracted data using a standardized form and the abstraction was verified by a second reviewer. We assessed study quality using a standardized approach. We quantitatively assessed population-based studies using the I2 statistic, and conducted random-effects meta-analyses. Results: We included 249 articles. Study designs were variable with respect to source populations, case definitions, methods of ascertainment and approaches to reporting findings. Prevalence was reported more frequently than incidence; estimates for prevalence and incidence varied substantially for all conditions. Heterogeneity was high. Conclusion: This review highlights substantial gaps in the epidemiological knowledge of comorbidity in MS worldwide. Little is known about comorbidity in Central or South America, Asia or Africa. Findings in North America and Europe are inconsistent. Future studies should report age-, sex- and ethnicity-specific estimates of incidence and prevalence, and standardize findings to a common population. PMID:25623244

To assess the association between genital cleansing practices and the prevalence of sexually transmitted diseases and of sexual health knowledge among female sex workers in Bali, Indonesia. Low priced commercial sex workers (CSWs) participated in the Bali STD/AIDS Study, a 3 year educational project evaluating the effect of education on the subsequent use of condoms and the prevalence of STDs and AIDS. Structured interviews, genital evaluation, laboratory evaluation for STDs, and treatment were performed. Vaginal cleansing characteristics including frequency, type, and reasons for use, were evaluated. Associations between these characteristics and the presence of bacterial and viral genital infections were assessed. Of 625 female sex workers evaluated between May and July 1998, 99.1% used substances, such as soap and toothpaste, to clean the vagina at least daily, with 69.3% performing this after each intercourse. The women using such cleansers after each client did not differ from those using them once or less daily in education, AIDS and condom use knowledge, time working as a CSW, or number of clients in the previous day. However, they were younger than those using vaginal cleansers daily or less, and reported lower condom usage in the past week. Several genital symptoms, such as discoloured discharge and odour, were reported less by women with the highest frequency of vaginal cleanser use. Prevalence of genital infections in this population of women was substantial, with bacterial infections more prevalent than viral infections. Infections were not associated with the type of cleanser used, using a genital cleanser on the day of examination, or using a cleanser after each client versus daily or less, except for candida colonisation, which was more prevalent in women cleansing after each client (OR=1.87, 95% CI 1.21, 2.90). However, symptomatic candida vulvovaginitis (positive culture plus presence of symptoms) was not associated with the prevalence of genital cleansing. Women using genital cleansing in part for "infection avoidance" (39.7%) were more likely to have heard of STDs and AIDS, but were less knowledgeable about these infections, compared with women not citing this reason for genital cleansing. Commercial sex workers in low priced brothels in Bali have a high rate of genital infections, with lower rates of viral compared with bacterial infections. Genital cleansers, on a daily or after each intercourse schedule, are used routinely. Although genital cleansing after each intercourse was associated with fewer genital symptoms, the prevalence of STDs did not differ significantly based on this frequency, and the women's knowledge of STDs and AIDS was less than that of women cleansing less often. The effect of genital cleansing in general on STD and AIDS prevalence could not be assessed in this population owing to the lack of a non-cleansing cohort. Further study to elucidate the effect of vaginal cleansing practices on STD prevalence and resistance is needed.

Opioid overdose is still the first cause of preventable death among young men in Barcelona. Sound knowledge of opioid overdose prevention is important to avoid complications and deaths. This study aimed to identify the factors associated with limited knowledge of overdose prevention and to assess the possible effect of treatment and overdose prevention training programs on this variable. From October 2008 to March 2009, current injecting opioid users attending harm reduction centers in Catalonia (Spain) were interviewed. Crude and adjusted prevalence ratios of limited knowledge about overdose prevention were calculated by adjusting Poisson regression models with a robust variance. In this sample, 28.7% of clients had limited knowledge of overdose prevention. Factors associated with limited knowledge were country of origin, never having received treatment for drug dependency, having a low educational level, and never having experienced an overdose. In contrast, treatment at the time of the interview was not associated with a lower prevalence of limited knowledge about overdose prevention. These findings suggest that preventive programs would benefit from accounting for linguistic and educational limitations and from participation in every treatment episode. Comprehensiveness and broad coverage of such programs could help to maximize their impact. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

Abstract There are no proper statistics available to assess how much of a burden it is to them. This study was conducted to gauge the pooled prevalence and offer evidence in support of few prevention and regulation strategies. A methodical literature search was conducted with the help of the Web of Knowledge, PubMed, Chinese Web of Knowledge, Wanfang, and Chongqing VIP databases. Furthermore, articles published from 2000 to 2014, reporting about the estimated prevalence of depression among college students in mainland China, were covered as well. In this study, a meta-analysis was deployed to approximate the overall prevalence of depression among college-goers in mainland China. A total of 45 studies were conducted on 50,826 participants. The average pooled prevalence of depression was 30.39% (26.38–34.55%). Subgroup analyses showed that 29.45% (22.88–36.48%) were men and 28.65% (23.44–34.16%) were women. Furthermore, 28.10% (22.83–33.70%) were from the northern part and 32.44% (26.67–38.48%) were from the southern. The prevalence of depression was 30.45% (23.96–37.36%) for sample sizes of <500 subjects, 30.99% (25.08–37.23%) for samples with 500 to 1000 people, and 29.54% (33.32–37.33%) in case of samples with >1000 people. Publications between 2000 and 2006 showed a depression prevalence of 8.45% (22.34–35.00%), whereas 30.52% (21.30–40.61%) and 31.79% (27.31–36.45%) were the corresponding values according to publications during 2007 to 2011 and 2012 to 2014. The prevalence of depression among college students in mainland China had reached the world's epidemic level. PMID:26683916

Background Publications on Libya’s HIV epidemic mostly examined the victims of the tragic nosocomial HIV outbreak in the 1990s and the related dispute about the detention of foreign medical workers. The dispute resolution in 2003 included an agreement with the European Union on humanitarian cooperation and the development of Libya’s first National HIV Strategy. As part of this we conducted Libya’s first bio-behavioural survey among men having sex with men (MSM) and female sex workers (FSW). Methods Using respondent-driven sampling, we conducted a cross-sectional study to estimate the prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and related risk factors among 227 MSM and 69 FSW in Tripoli (FSW recruitment ended prematurely due to the political events in 2011). Results For MSM we estimated an HIV prevalence of 3.1%, HBV prevalence of 2.9%, and HCV prevalence of 7.3%, and for FSW an HIV prevalence of 15.7%, HBV prevalence of 0%, and HCV prevalence of 5.2%. We detected high levels of risk behaviours, poor HIV-related knowledge, high stigma and lack of prevention programmes. These results must be interpreted in the context of the political situation which prohibited reaching an ideal sample size for FSW. Conclusion There is urgent need to implement an effective National HIV Strategy informed by the results of this research. The risk of transmission within different risk groups and to the general population may be high given the recent military events that led to increased violence, migration, and the disruption of essential HIV-related services.

Introduction. Community-acquired urinary tract infections (CAUTIs) are usually treated empirically. Geographical variations in etiologic agents and their antibiotic sensitivity patterns are common. Knowledge of antibiotic resistance trends is important for improving evidence-based recommendations for empirical treatment of UTIs. Our aim was to determine the major bacterial etiologies of CAUTIs and their antibiotic resistance patterns in a cosmopolitan area of Cameroon for comparison with prescription practices of local physicians. Methods. We performed a cross-sectional descriptive study at two main hospitals in Yaoundé, collecting a clean-catch mid-stream urine sample from 92 patients having a clinical diagnosis of UTI. The empirical antibiotherapy was noted, and identification of bacterial species was done on CLED agar; antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Results. A total of 55 patients had samples positive for a UTI. Ciprofloxacin and amoxicillin/clavulanic acid were the most empirically prescribed antibiotics (30.9% and 23.6%, resp.); bacterial isolates showed high prevalence of resistance to both compounds. Escherichia coli (50.9%) was the most common pathogen, followed by Klebsiella pneumoniae (16.4%). Prevalence of resistance for ciprofloxacin was higher compared to newer quinolones. Conclusions. E. coli and K. pneumoniae were the predominant bacterial etiologies; the prevalence of resistance to commonly prescribed antibiotics was high.

To determine prevalence of heel strike in a midsize city marathon, if there is an association between foot-strike classification and race performance, and if there is an association between foot-strike classification and gender. Foot-strike classification (forefoot, midfoot, heel, or split strike), gender, and rank (position in race) were recorded at the 8.1-km mark for 2112 runners at the 2011 Milwaukee Lakefront Marathon. 1991 runners were classified by foot-strike pattern, revealing a heel-strike prevalence of 93.67% (n = 1865). A significant difference between foot-strike classification and performance was found using a Kruskal-Wallis test (P < .0001), with more elite performers being less likely to heel strike. No significant difference between foot-strike classification and gender was found using a Fisher exact test. In addition, subgroup analysis of the 126 non-heel strikers found no significant difference between shoe wear and performance using a Kruskal-Wallis test. The high prevalence of heel striking observed in this study reflects the foot-strike pattern of most mid-distance to long-distance runners and, more important, may predict their injury profile based on the biomechanics of a heel-strike running pattern. This knowledge can help clinicians appropriately diagnose, manage, and train modifications of injured runners.

In Vietnam, hypertension was estimated to cause a large number of deaths in hospitals. However, population-based knowledge about the magnitude of hypertension in Vietnam and its relationship with socioeconomic status, especially in the rural communities, still remains scarce. This paper, taking advantage of a study on noncommunicable disease (NCD) risk factors in Bavi district, Vietnam, using the WHO STEPs approach, estimates the prevalence of hypertension in the setting and examines its association with some socioeconomic factors. A representative sample comprising 2000 adults aged 25-64 years were selected randomly and surveyed in 2002. The JNC VII criteria for hypertension were used. Socioeconomic status of the study subjects was estimated by assessing their education, occupation and economic conditions. Descriptive techniques and multivariate logistic regression were used. The prevalence of hypertension was 14.1%. Of hypertensives, only 17.4% were aware of their hypertensive status. Men were hypertensive more often than women and age was positively associated with hypertension. The association between hypertension and socioeconomic status was complex and differed between men and women. Among men, those with lower educational and occupational status but who were richer were more likely to be hypertensive. More women with lower occupational and economic status were hypertensive.

Smokeless tobacco consumption is one of the causes of oral cancer. The aim of this study was to determine the prevalence of smokeless tobacco consumption among male students of Zahedan universities and associated factors in 2012. In this cross-sectional study, 431 students were selected from the universities of Zahedan using multi-stage random cluster sampling. The data collection tool was a questionnaire including questions about demographic information, history of smokeless tobacco consumption, and awareness of smokeless tobacco hazards. Data were analyzed by SPSS19 using Chi-square test and multinomial logistic regression, with p<0.05 considered significant. At the time of conducting this study, 102 students (23.7%) had already consumed smokeless tobacco and 49 students (11.4%) were current users (consuming at least once in 30 days before the study). There was a significant relationship between history of smokeless tobacco consumption, university/college, place of living, mean GPA, and mother's education level (p<0.05). Also there was a significant association between knowledge and prevalence of smokeless tobacco use (p<0.001). There is a relatively high prevalence of smokeless tobacco consumption among the male students of universities of Zahedan, which shows the need to emphasize the provision and implementation of prevention programs in universities.

To investigate the effect of demographic, socioeconomic, educational and family variables on HIV/AIDS knowledge among adolescents aged 11 years. 3,949 adolescents born in Pelotas (Brazil). HIV/AIDS knowledge was assessed through a self-administered questionnaire and measured through five questions about HIV transmission: heterosexual intercourse, homosexual intercourse, needle sharing, open-mouth kissing and hugging someone with AIDS. All the analyses were adjusted based on a hierarchical model, using Poisson regression with robust adjustment of variance. Prevalence of wrong answers to the examined questions were 17.2% for heterosexual transmission, 44.1% for homosexual intercourse, 34.9% for needle sharing, 25.6% for kiss on the mouth and 16.2% for hugging someone with AIDS. In adjusted analysis, lower knowledge levels were more prevalent among boys, adolescents with lower socioeconomic status and with less maternal education level, among those who had not talked about sex with mother and without sexual education lessons at school. Knowledge was not associated with school type (public or private), skin color or talk about sex with father. Providing information to adolescents is essential to improve knowledge about HIV and other sexually transmitted infections, especially among young males, with lower socioeconomic status and with lower maternal education level. Public policies aimed to reducing HIV infection should consider maternal and school relevance to improve knowledge on adolescents.

The objective of this investigation was to determine the prevalence and characteristics of extended-spectrum-β-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae in ready-to-eat (RTE) vegetables. A total of 189 RTE vegetable samples (91 sprouts and 98 mixed salads) were collected in a retail market in South Korea from October 2012 to February 2013. The prevalence of ESBL-producing E. coli and K. pneumoniae was 10.1%. Of these, 94.7% were from the sprout samples. All isolates were resistant to cefotaxime, and many of the ESBL producers were also resistant to non-β-lactam antibiotics, including gentamicin, trimethoprim/sulfamethoxazole, and ciprofloxacin (73.7%, 63.2%, and 26.3% respectively). TEM-1, SHV-1, -2, -11, -12, -27, -28 and -61, and CTX-M-14, -15 and -55 β-lactamases were detected alone or in combination. The genetic platforms of all CTX-M producing isolates were ISEcp1-blaCTX-M-orf477 and ISEcp1-blaCTX-M-IS903 in CTX-M groups 1 and 9, respectively. To our knowledge, this is the first report of the prevalence and characterization of ESBL-producing E. coli and K. pneumoniae isolated from RTE vegetables. The results of this study indicate that RTE vegetables, sprouts, in particular, may play a role in spreading antimicrobial resistant bacteria and ESBL genes to humans. Copyright © 2015 Elsevier B.V.

The aim of the study was to explore prevalence of food allergies and intolerances among children in preschools in Reykjavik, Iceland. Also, to investigate how well preschools maintain a safe environment for children with food allergies. In 2014, a questionnaire designed specifically for this study, was sent to 65 preschools. Forty-nine participated (75%) representing a total of 4225 children. Prevalence of food allergy and intolerance was determined based on medical certificates from physi-cians delivered to the preschools. Descriptive statistics were used to assess whether there were protocols related to food allergy, and if there was a difference between schools based on staff's education and number of children. The prevalence of documented food allergies/intolerances in children aged 2-6 years was 5%, 1% had severe allergy and 1% had multiple food allergies. Lactose intolerance was most frequent (2%), then milk allergy (2%) and egg allergy (1%). Only 41% preschools had a protocol that was activated if food with an allergen was accidentally given. Moreover, only 55% of preschools with children with severe -allergy reported all of their staff to have knowledge of symptoms related to anaphylaxis and only 64% were trained to respond to an anaphylactic shock. The education of preschool principals, kitchen employees and number of children in preschool were not related to having an active protocol at site. Prevalence of food allergy and intolerance was 5% in preschools in Reykjavik. Strategy for an active protocol related to food allergy was lacking in 59% of pre-schools.

In many developing countries nutritional, and epidemiological transitions are emerging into continuing undernutrition and escalating overnutrition, giving rise to the double burden of the malnutrition phenomenon. This study aims to determine the prevalence of the dual form of malnutrition (overweight mother/underweight child) in the same household and its associated factors in the Gaza Strip. A total of 357 mother-child pairs from the same households were surveyed from three different geographical locations in the Gaza Strip, namely, El Remal urban area, Jabalia refugee camp, and Al Qarara rural area. The height and weight of mothers aged 18-50 years were measured, and their body mass index (BMI) was computed. The mothers were categorized according to the criterion of the World Health Organization (WHO) for BMI as overweight if they have a BMI ≥ 25 kg/m2. Anthropometric indices were measured for children aged two to five years to classify the underweight children Z-score <-1. The results showed the prevalence of the dual form of malnutrition in the Gaza Strip was 15.7%, and its associated factors were child's birth order (ORadj, 1.50, 95% CL, 1.22, 1.82; p = <0.001), father's educational (low or medium) levels (ORadj, 3.19, 95% CL, 1.07, 9.5; p = 0. 036), or (ORadj, 3.4, 95% CL, 1.12, 10.37; p = 0. 031), high scores of mothers' nutrition knowledge (ORadj, 1.23, 95% CL, 1.01, 1.52; p = 0. 048), and low monthly income (ORadj, 0.28, 95% CL, 0.09, 0.88; p = 0. 030). The results from this study showed the dual form of malnutrition in the same household was prevalent in the Gaza Strip. This is a public health issue that must be understood and addressed and policy makers must implement an appropriate nutrition action plan to control dual form of malnutrition based on the underlying specific risk factors in the study population. In addition, interventions are needed to help individuals to translate their nutrition knowledge into healthy dietary behaviors.

Current smoking prevalence in Thailand decreased from 1991 to 2004 and since that time the prevalence has remained flat. It has been suggested that one of the reasons that the prevalence of current smoking in Thailand has stopped decreasing is due to the use of RYO cigarettes. The aim of this study was to examine characteristics of users of manufactured and RYO cigarettes and dual users in Thailand, in order to determine whether there are differences in the characteristics of users of the different products. The 2009 Global Adult Tobacco Survey (GATS Thailand) provides detailed information on current smoking patterns. GATS Thailand used a nationally and regionally representative probability sample of 20,566 adults (ages 15 years and above) who were chosen through stratified three-stage cluster sampling and then interviewed face-to-face. The prevalence of current smoking among Thai adults was 45.6% for men and 3.1% for women. In all, 18.4% of men and 1.0% of women were current users of manufactured cigarettes only, while 15.8% of men and 1.7% of women were current users of RYO cigarettes only. 11.2% of men and 0.1% of women used both RYO and manufactured cigarettes. Users of manufactured cigarettes were younger and users of RYO were older. RYO smokers were more likely to live in rural areas. Smokers of manufactured cigarettes appeared to be more knowledgeable about the health risks of tobacco use. However, the difference was confounded with age and education; when demographic variables were controlled, the knowledge differences no longer remained. Smokers of manufactured cigarettes were more likely than dual users and those who used only RYO to report that they were planning on quitting in the next month. Users of RYO only appeared to be more addicted than the other two groups as measured by time to first cigarette. There appears to be a need for product targeted cessation and prevention efforts that are directed toward specific population subgroups in Thailand and include information on manufactured and RYO cigarettes.

Objective The goal of this study was to understand the knowledge about AIDS, identify the correlates and determine the prevalence of HIV infection, syphilis, HCV among migrant workers in Zhejiang, China. Methods A cross-sectional study using face-to-face anonymous questionnaire interviews was conducted and blood samples were collected for HIV, syphilis and Hepatitis C infection screening. Results 17,377 (92.8%) of 18,730 migrant workers approached were interviewed. Among 17,377 participants, the HIV/AIDS knowledge rate was 66.2%. A total of 12,694 (73%) of the participants reported having ever had sexual intercourse, with 30.1% of single participants reporting having had sexual intercourse. Among those respondents with sexual experiences, 7.5% admitted they had two or more sexual partners and 4.9% reported having had sex with casual (unpaid) partners in the previous 12 months, whilst 3.7% had paid for sex. More than half of those who had paid for sex (59.4%) had not used a condom every time in their sexual acts with the sex workers. Multiple logistic regression analysis indicated that high risk sexual behavior (defined as sex with a casual or commercial sex partner without using a condom consistently) was associated with being divorced or widowed (P<0.05 for single); male gender; shorter duration of stay in Zhejiang; working in factory, market or domestic service (P<0.05 for odd job); having a province of origin inside Zhejiang; and drug use. The prevalence of HIV and HCV infections were 0.02% (95% CI: 0.01%–0.06%) and 0.40% (95%CI: 0.31%–0.51%), respectively. The prevalence of syphilis among those who were sexually active was 0.55% (95% CI: 0.43%–0.70%). Risk factors for syphilis included shorter duration of stay in Zhejiang, ethnic minority status, being divorced or widowed and having had multiple sex partners. Conclusions Much greater efforts are needed to promote safer sex, and programs for the control of syphilis need to be tailored for migrant workers in China. PMID:23451193

This study compares sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. From the Barakholka Market, 209 male and 213 female market vendors were randomly recruited. Self-reported data were collected through standardized face-to-face interviews. Dry blood spot was used as specimen for syphilis testing. Propensity score stratification was used to estimate adjusted prevalence or rate ratios by gender. Compared to male migrant workers, females had lower HIV knowledge and were less likely to have multiple sexual partners. There was no evidence of a gender difference for prevalence of syphilis, condom use with unsteady partners, and safe sex communication between couples. Associations between mobility patterns and engagement in multiple sexual partnerships were stronger among women than men. Efforts should be made to mitigate the gender differential in HIV knowledge among migrants, especially women. Such efforts need to be implemented in both home and host countries.

This study aimed to identify associations between GP patient's knowledge about the spectrum of effectiveness of antibiotics and the probability of vaccination against influenza. The underlying hypothesis was that individuals with an understanding that antibiotics are ineffective against viruses, common colds, and flu were more likely to be vaccinated than persons lacking this knowledge. This cross-sectional study was conducted within the context of the European APRES project in Austria. Between November 2010 and July 2011, patients were recruited from GP practices to complete questionnaires about their knowledge about antibiotics and their influenza vaccination status. Statistical analyses included subgroup analyses and logistic regression models. Data of 3224 patients was analyzed, demonstrating that patients with better knowledge concerning antibiotics had a significantly higher likelihood of being vaccinated (OR 1.35, CI 95 % 1.18-1.54). While the overall vaccination rate was low (18.6 % in 2009/2010 and 14.0 % in 2010/2011), elderly compared to younger adults (OR 0.06 CI 95 % 0.03-0.13) and healthcare workers (OR 2.24, CI 95 % 1.42-3.54) demonstrated higher likelihood of vaccination. Additionally, female GPs had significantly more vaccinated patients than male GPs (OR 2.90, CI 95 % 1.32-6.40). There has been little prior study on the association between a patient's knowledge of the effectiveness spectrum of antibiotics and influenza vaccination status. Given the public health imperative to increase annual prevalence of influenza vaccination, understanding this educational gap can improve specificity in counseling as well as vaccination rates. Ultimately, we found that those with a better knowledge on about antibiotics had a significantly higher likelihood of being vaccinated. The results of this study demonstrate that vaccination prevalence is associated with patient's knowledge about antibiotics. It can be concluded that one strategy to improve the overall low vaccination rates for seasonal influenza in Austria would be, particularly for male GPs, to have a specific discussion with patients about these circumstances by focusing on younger patients. Further, public health efforts could supplement in-office strategies to improve this area of health literacy.

This study was completed to determine the current knowledge and documentation patterns of nursing staff in the prevention of pressure ulcers and to identify the prevalence of pressure ulcers. This pre-post intervention study was carried out in three phases. In phase 1, 67 nursing staff members completed a modified version of Bostrom's Patient Skin Integrity Survey. A Braden Scale score, the presence of actual skin breakdown, and the presence of nursing documentation were collected for each patient (n = 43). Phase II consisted of a 20-minute educational session to all staff. In phase III, 51 nursing staff completed a second questionnaire similar to that completed in phase I. Patient data (n = 49) were again collected using the same procedure as phase I. Twenty-seven staff members completed questionnaires in both phase I and phase III of the study. No statistically significant differences were found in the knowledge of the staff before or after the educational session. The number of patients with a documented plan of care showed a statistically significant difference from phase I to phase III. The number of patients with pressure ulcers or at risk for pressure ulcer development (determined by a Braden Scale score of 16 or less) did not differ statistically from phase I to phase III. Knowledge about pressure ulcers in this sample of staff nurses was for the most part current and consistent with the recommendations in the Agency for Health Care Policy and Research guideline. Documentation of pressure ulcer prevention and treatment improved after the educational session. Although a significant change was noted in documentation, it is unclear whether it reflected an actual change in practice.

Ineffective communication among the health care team is a leading cause of errors in the patient care setting. Studies assessing training related to communication and teamwork in the clinical team are prevalent, however, teamwork training at the administrative level is lacking. This includes individuals in leadership positions such as health care risk managers. The purpose was to determine the impact of an educational intervention on the knowledge and attitudes related to communication and teamwork in the health care risk management population. The educational intervention was an adaptation of a national teamwork training program and incorporated didactic content as well as video vignettes and small group activities. Measurement of knowledge and attitudes were used to determine the impact of the education program. Knowledge and attitudes were assessed pre- and postcourse. Findings indicate that teamwork education tailored to the needs of the specific audience resulted in knowledge gained and improved attitudes toward the components of teamwork. The attitudes that most significantly improved were related to team structure and situation monitoring. There was no improvement in participants' attitudes toward leadership, mutual support, and communication. Team training has been shown to improve safety culture, patient satisfaction, and clinical outcomes. Including risk managers in training on teamwork, communication, and collaboration can serve to foster a common language among clinicians and management. In addition, a measurement related to implementation in the health care setting may yield insight into the impact of training. Qualitative measurement may allow the researcher to delve deeper into how these health care facilities are using team training interventions. © 2016 American Society for Healthcare Risk Management of the American Hospital Association.

The prevalence of dementia is increasing in Australia. Limited research is available on access to Cognitive Dementia and Memory Services (CDAMS) for people with dementia from Culturally and Linguistically Diverse (CALD) communities. This study aimed to determine the barriers and enablers to accessing CDAMS for people with dementia and their families of Chinese and Vietnamese backgrounds. Consultations with community members, community workers and health professionals were conducted using the "Cultural Exchange Model" framework. For carers, barriers to accessing services included the complexity of the health system, lack of time, travel required to get to services, language barriers, interpreters and lack of knowledge of services. Similarly, community workers and health professionals identified language, interpreters, and community perceptions as key barriers to service access. Strategies to increase knowledge included providing information via radio, printed material and education in community group settings. The "Cultural Exchange Model" enabled engagement with and modification of the approaches to meet the needs of the targeted CALD communities.

There has been a growing interest in patterns of contraceptive use among adolescents, due, in particular, to the social relevance attached to pregnancy in this age group. Therefore, the objective of the study was to investigate factors associated with the use of contraceptive methods among female adolescent students. A cross-sectional study was conducted, by means of selfapplied questionnaires, among 500 adolescent girls ranging from 15to 19 years of age. Prevalence with respect to the knowledge of contraceptive methods, condom use, and AIDS was calculated. Among the 500 students who participated in study only one was sexually active .The factors associated with knowledge lack and misconception are less discussion at home or at school or college level. There were many negative beliefs like impotence after condom use, weakness after sterilization, fear of becoming obese as reasons for choosing different contraceptive methods. These results confirm the there is a need for reproductive health education in school and college as well as robust research to determine the contraceptive needs of adolescents.

The burden of malaria in mobile populations remains poorly documented in sub-Saharan Africa. This study determined the prevalence of malaria among hawkers and long-distance truck drivers in the Greater Accra region of Ghana. A cross-sectional design using consecutive sampling method between June and July 2016 in Accra and Tema in Ghana was used in this study. The study population was hawkers who roam and sleep in the Market Streets, and long-distance truck drivers. Participants completed closed ended interview questionnaires on socio-demographic characteristics, primary residence and knowledge about malaria. Rapid diagnostic test and thick blood smears of each participant were stained with Giemsa and read using microscopy. Geographical position system (GPS) was used to collect the station locations of these mobile populations. The overall prevalence of malaria was 15.1% and Plasmodium falciparum was responsible for all malaria infection. The malaria prevalence was 18.9 and 10.9% respectively among hawkers and truck drivers (p < 0.05). The hawkers, the single and the no formal educated participants were more likely to get malaria than the long-distance truck drivers (OR = 1.91, 95% CI 1.07-3.42), the married (OR = 1.94 95% CI 1.11-3.40) and the educated participants (OR = 2.56 95% CI 1.10-5.93), respectively. After controlling for other variables, marital status (OR = 2.60 95% CI 1.43- 4.73) and educational level (OR = 2.70 95% CI 1.08-6.77) were statistically significantly associated with malaria. This study demonstrated that the prevalence of malaria is high among hawkers and long distance truck drivers. Sociodemographic characteristics, such as marital status, occupation and educational level are significantly associated with malaria. The station locations as determined by GPS technology will make these mobile populations easier to reach for any malaria intervention.

ABSTRACT The knowledge of the internal anatomy of three-rooted mandibular molars may help clinicians to diagnose and plan the root canal treatment in order to provide adequate therapy when this variation is present. Objectives: To determine the prevalence of three-rooted mandibular molars in a Brazilian population using cone beam computed tomography (CBCT) and to analyze the anatomy of mandibular first molars with three roots through micro-CT. Material and Methods: CBCT images of 116 patients were reviewed to determine the prevalence of three-rooted first mandibular molars in a Brazilian subpopulation. Furthermore, with the use of micro-CT, 55 extracted three-rooted mandibular first molars were scanned and reconstructed to assess root length, distance between canal orifices, apical diameter, Vertucci's classification, presence of apical delta, number of foramina and furcations, lateral and accessory canals. The distance between the orifice on the pulp chamber floor and the beginning of the curvature and the angle of canal curvature were analyzed in the distolingual root. Data were compared using the Kruskal-Wallis test (α=0.05). Results: The prevalence of three-rooted mandibular first molars was of 2.58%. Mesial roots showed complex distribution of the root canal system in comparison to the distal roots. The median of major diameters of mesiobuccal, mesiolingual and single mesial canals were: 0.34, 0.41 and 0.60 mm, respectively. The higher values of major diameters were found in the distobuccal canals (0.56 mm) and the lower diameters in the distolingual canals (0.29 mm). The lowest orifice distance was found between the mesial canals (MB-ML) and the highest distance between the distal root canals (DB-DL). Almost all distal roots had one root canal and one apical foramen with few accessory canals. Conclusions: Distolingual root generally has short length, severe curvature and a single root canal with low apical diameter. PMID:27812625

The purpose of this study was to determine the prevalence and severity of dental caries in preschool children from nurseries and kindergartens in Iaşi, an urban city in Romania. The study assessed the dental health status in 2 age groups. The first group included 366 children aged 2, 5-3 years and the second group included 455 children aged 4,5-5 years in 2005. The children were subjected to dental examination in 2005 and 2006 and the prevalence and severity of caries for each age group were determined. Evaluation was based on questionnaire completed by mothers and on clinical assessment of preschool children's oral health status. The mean number of decayed, missing and filled primary teeth (dmft) in the first group was 1.76 in 2005 and 2.39 in 2006, while the significant caries index increased from 4.79 to 6.35 during this period of time. For the 4.5-5 year children, the mean values for the dmft index were 3.95 in 2005 and 3.67 in 2006, while significant caries index increased from 7.89 to 8.4. Early childhood caries are the result of both inadequate diet behavior and cariogenic germs transmission from mother. The presence and extension of carious lesions in primary teeth are the most important predictors of permanent teeth disease. The high prevalence and severity of dental caries in pre-school children indicated that dental health program that include both prevention and treatment services targeted for young children and their parents is urgently needed. Socio-economic status improvement, changes in lifestyle, effective use of oral health services, and most of all, oral hygiene and use of fluoride would lead to obvious changes in caries prevalence and severity of disease. The study high-lights the importance of change of attitudes and improvement of knowledge in parents, children and educators in order to reach a healthy lifestyle.

Although dehydration of ≥ 2% body weight (BW) loss significantly impairs endurance performance, dehydration remains prevalent among athletes and may be owing to a lack of knowledge in relation to fluid requirements. The aim of this study was to assess the hydration status of university/club level athletes (n = 430) from a range of sports/activities (army officer cadet training; bootcamp training; cycling; Gaelic Athletic Association camogie, football and hurling; golf; hockey; netball; rugby; running (sprinting and endurance); Shotokan karate and soccer) immediately before and after training/competition and to assess their nutritional knowledge. Urine specific gravity (USG) was measured immediately before and after exercise and BW loss during exercise was assessed. Nutritional knowledge was assessed using a validated questionnaire. 31.9% of athletes commenced exercise in a dehydrated state (USG >1.020) with 43.6% of participants dehydrated posttraining/competition. Dehydration was particularly prevalent (>40% of cohort) among karateka, female netball players, army officer cadets, and golfers. Golfers that commenced a competitive 18 hole round dehydrated took a significantly higher number of strokes to complete the round in comparison with their euhydrated counterparts (79.5 ± 2.1 vs. 75.7 ± 3.9 strokes, p = .049). Nutritional knowledge was poor among participants (median total score [IQR]; 52.9% [46.0, 59.8]), albeit athletes who were euhydrated at the start of exercise had a higher overall score in comparison with dehydrated athletes (55.2% vs. 50.6%, p = .001). Findings from the current study, therefore, have significant implications for the education of athletes in relation to their individual fluid requirements around exercise.

The reported prevalence of infertility in Pakistan is approximately 22% with 4% primary and 18% secondary infertility. Infertility is not only a medical but also a social problem in our society as cultural customs and perceived religious dictums may equate infertility with failure on a personal, interpersonal, or social level. It is imperative that people have adequate knowledge about infertility so couples can seek timely medical care and misconceptions can be rectified. We aim to assess the knowledge, perception and myths regarding infertility and suggest ways to improve it. A cross-sectional survey was carried out by interviewing a sample of 447 adults who were accompanying the patients at two tertiary care hospitals in Karachi, Pakistan. They were interviewed one-on-one with the help of a pretested questionnaire drafted by the team after a thorough literature review and in consultation with infertility specialists. The correct knowledge of infertility was found to be limited amongst the participants. Only 25% correctly identified when infertility is pathological and only 46% knew about the fertile period in women's cycle. People are misinformed that use of IUCD (53%) and OCPs (61%) may cause infertility. Beliefs in evil forces and supernatural powers as a cause of infertility are still prevalent especially amongst people with lower level of education. Seeking alternative treatment for infertility remains a popular option for 28% of the participant as a primary preference and 75% as a secondary preference. IVF remains an unfamiliar (78%) and an unacceptable option (55%). Knowledge about infertility is limited in the population and a lot of misconceptions and myths are prevalent in the society. Alternative medicine is a popular option for seeking infertility treatment. The cultural and religious perspective about assisted reproductive technologies is unclear, which has resulted in its reduced acceptability.

Psychotropic drug use among people with intellectual disability before and after deinstitutionalization.

The use of psychotropic medication among people with intellectual disability (ID) is widespread, and they are one of the most medicated groups in society. A substantial number of individuals with ID receive psychotropic medications that may be inappropriate for their diagnosis. One of the main reasons for the use of psychotropic medication is challenging behaviours. Almost all prevalence studies show higher prevalence rates of psychotropic medication in institutions compared with community living. Studies on deinstitutionalization and the use of psychotropic medication are few and inconclusive. The present study is a prospective cohort study without control group. It examines the use of psychotropic medication among 109 subjects aged between 16 and 65 years before (1987) and after (1995) deinstitutionalization. Psychotropic drug dosages were transformed to percentage of defined daily dosage. We found no major changes in the use of neuroleptics after deinstitutionalization neither in frequency nor in dosages, and the trend seemed indiscriminate in relation to diagnosis. The people with schizophrenia or an anxiety disorder did not receive proper drug treatment, nor did they before deinstitutionalization. The main predictor variable for neuroleptic dosage both before and after deinstitutionalization was challenging behaviour. The reason for this may be the difficulties in determining the extent to which presenting behaviours are the result of a psychiatric disorder or a behaviour disorder, the lack of knowledge among the caretakers and the ensuing referral practice, the lack of knowledge among the general practitioners, and the lack of access to specialized health services.

To determine the prevalence of anaemia and associated factors among under-fives and their mothers in a rural area of Western Uganda. A cross-sectional investigation using both qualitative and quantitative methods of data collection. Stratified multistage sampling methods were used to select the study sample. A haemoglobinometer was used to assess Hb levels in the blood. A rural district in Western Uganda. Children aged 6-59 months and their mothers aged 15-49 years. The overall prevalence of Fe-deficiency anaemia among children and their mothers was 26.2 % and 17.9 %, respectively. There was a significant correlation (r = 0.5, P = 0.008) between the Hb levels of the mothers and their children. Place of birth, age of the child, factors related to complementary foods, and formal education and nutrition knowledge of the mother were major factors that were significantly associated (r = 0.05, P = 0.05) with low Hb levels among the children. The most important factors that were associated with low Hb levels of the mothers were their formal education, nutrition knowledge and health status. Fe-deficiency anaemia was found to be a major problem in this cohort of children and their mothers. Dietary factors and sociodemographic factors were the major factors associated with high levels of anaemia among the children and their mothers. It is therefore recommended that rural mothers should be sensitized on best practices for prevention of anaemia among both women and children.

Background This study was conducted to develop a questionnaire in order to evaluate knowledge, attitude and practice (KAP) of the faculty members and students toward plagiarism. Methods: A KAP study was conducted from June to October 2011 enrolling 390 volunteers anonymously (response rate 96%). The questionnaire included the following four parts: (a) general characteristics like gender, academic degree and education level; (b) nine questions regarding knowledge (Min=0, Max=9); (c) nine questions regarding attitude (Min=9, Max=27); and (d) eight questions regarding practice (Min=0, Max=8). A pilot study was conducted to assess reliability of the questions regarding knowledge and attitude. Cronbach’s alpha coefficient for the knowledge and attitude questions was 0.70 and 0.74 respectively. Results: The overall prevalence of at least once plagiarism commission was 38% (SD=0.035). The overall mean score of knowledge, attitude and practice was 5.94 (SD=1.66), 24.12 (SD=2.99), and 0.66 (SD=1.15) respectively. Knowledge of plagiarism was significantly higher among higher academic degrees and females. Their negative attitude toward plagiarism was stronger too. No statistically significant difference regarding plagiarism commission was observed among different academic degrees in both sexes. According to linear regression analysis, plagiarism commission decreased 13% per one unit increase in score of knowledge (P=0.005) and 16% per one unit increase in score of attitude (P<0.001). Conclusions: This knowledge, attitude, and practice (KAP) questionnaire was developed as a standard tool in order to assess perception of subjects toward plagiarism and to estimate the prevalence and the type of plagiarism commission.

An Ecological Approach Toward Prevention and Care of Victims of Domestic Minor Sex Trafficking.

PubMed

Sanchez, Rosario V; Pacquiao, Dula F

Sex trafficking is a widespread form of human trafficking that exists globally. The forced sexual exploitation of young women for profit at the hands of traffickers is a human rights violation. Sex trafficking is a form of modern-day slavery where youths are sold as a commodity. It is difficult to determine the wide range of negative health outcomes associated with domestic minor sex trafficking due to the hidden nature of the crime and its lack of statistical data to determine prevalence. Viewing domestic minor sex trafficking through an ecological lens assists in the understanding of the multiple complex interactions between victims, their relationships, and environments that influence their health. Forensic nurses are poised as experts in the healthcare of vulnerable populations and possess the knowledge to understand that social determinants of vulnerability depend on the distinct setting or environment where victims of sex trafficking reside and how different factors affect their victimology, resilience, and well-being.

Nonalcoholic fatty liver disease (NAFLD) is a major chronic liver disease in children in the United States and is associated with insulin resistance. In adults, NAFLD is also associated with type 2 diabetes. To our knowledge, the prevalence of type 2 diabetes in children with NAFLD is unknown. To determine the prevalence of type 2 diabetes and prediabetes in children with NAFLD and assess type 2 diabetes and prediabetes as risk factors for nonalcoholic steatohepatitis (NASH). This was a multicenter, cross-sectional study at 12 pediatric clinical centers across the United States participating in the National Institute of Diabetes and Digestive and Kidney Diseases NASH Clinical Research Network. Children younger than 18 years with biopsy-confirmed NAFLD enrolled in the NASH Clinical Research Network. The presence of type 2 diabetes and prediabetes as determined by American Diabetes Association screening criteria using clinical history and fasting laboratory values. There were 675 children with NAFLD included in the study with a mean age of 12.6 years and mean body mass index (calculated as weight in kilograms divided by height in meters squared) of 32.5. Most of the children were boys (480 of 675) and Hispanic (445 of 675).The estimated prevalence of prediabetes was 23.4% (95% CI, 20.2%-26.6%), and the estimated prevalence of type 2 diabetes was 6.5% (95% CI, 4.6%-8.4%). Girls with NAFLD had 1.6 (95% CI, 1.04-2.40) times greater odds of having prediabetes and 5.0 (95% CI, 2.49-9.98) times greater odds of having type 2 diabetes than boys with NAFLD. The prevalence of NASH was higher in those with type 2 diabetes (43.2%) compared with prediabetes (34.2%) or normal glucose (22%) (P < .001). The odds of having NASH were significantly higher in those with prediabetes (OR, 1.9; 95% CI, 1.21-2.9) or type 2 diabetes (OR, 3.1; 95% CI, 1.5-6.2) compared with those with normal glucose. In this study, nearly 30% of children with NAFLD also had type 2 diabetes or prediabetes. These children had greater odds of having NASH and thus were at greater long-term risk for adverse hepatic outcomes.

Approximately 80% of deaths attributed to malaria worldwide occurred mainly in Africa in 2015. Kenya is one of the major malaria endemic countries, making malaria the leading public health concern in this country. This study intended to document the prevalence of malaria and determine associated factors including socioeconomic status among children aged 6 months to 14 years in Kenya. This study analyzed the secondary data extracted from the 2015 Kenya Malaria Indicator Survey (KMIS), a cross-sectional country representative survey. Associations of demographic, socioeconomic, community-based, and behavioral factors with the prevalence of malaria in children were analyzed using multivariable logistic regression analysis. Data from 7040 children aged 6 months to 14 years were analyzed. The prevalence of malaria showed an upward trend in terms of age, with the highest prevalence among children aged 11-14 years. Prevalence was also higher among rural children (10.16%) compared to urban children (2.93%), as well as poor children (11.05%) compared to rich children (3.23%). The likelihood of having malaria was higher among children aged 10-14 years (AOR = 4.47, 95% CI = 3.33, 6.02; P <  0.001) compared with children aged under 5 years. The presence of anemia (AOR = 3.52, 95% CI = 2.78, 4.45; P  < 0.001), rural residence (AOR = 1.71, 95% CI = 1.31, 2.22; P <  0.001), lack of a hanging mosquito net (AOR = 2.38, 95% CI = 1.78, 3.19; P <  0.001), primary education level of the household head (AOR = 1.15, 95% CI = 1.08, 2.25; P <  0.05), and other factors, such as the household having electricity and access to media such as television or radio, were also associated with the likelihood of infection. This study demonstrated the need to focus on awareness programs to prevent malaria and to use existing knowledge in practice to control the malaria burden in Kenya. Furthermore, this study suggests that improving the information available through the mass media and introducing behavior change communication and intervention program specifically for those of poor socioeconomic status will help to reduce malaria cases.

Objectives To estimate the prevalence of HIV and related risk behaviours among prisoners in Iran in 2009. Methods Using multistage random sampling, we recruited 5,530 prisoners from 27 prisons in Iran. Behavioural data were collected using a face-to-face questionnaire-based interview, and HIV status was determined by ELISA of dried blood spots. Weighted estimates were calculated based on the sampling probability and response rate. Results HIV prevalence was 2.1% (95% CI 1.2 to 3.6). One in eight prisoners (12.3%, 95% CI 8.0% to 16.6%) had been tested for HIV in the last year and received results, 20.5% (95% CI 15.1 to 27.4%) had comprehensive knowledge about HIV and 24.7% (95% CI 17.9% to 32.9%) reported condom use at last vaginal/anal sex in prison. Although 16.5% (95% CI 12.5% to 21.5%) acknowledged a lifetime history of drug injection, only 22 prisoners reported drug injection inside the prison in the month preceding the interview. Of note, 12.9% (95% CI 10.6% to 15.6%) had been tattooed in prison. There were significant associations between HIV prevalence and a history of drug injection (adjusted odds ratio (AOR): 7.8, 95% CI 4.7 to 13.2), tattooing (AOR: 2.1, 95% CI 1.1 to 4.2) and age over 30 years (AOR: 1.4, 95% CI 1.1 to 1.9). Conclusions Considerable HIV prevalence among prisoners is found in Iran. Expanding harm reduction programmes inside prisons with inclusion of sexual risk reduction programmes and post-release programmes will help directly prevent acquisition and transmission of infection inside prisons and indirectly slow onward transmission in the outside communities.

The prevalence of phenotypic females with a 46,XY karyotype is low, thus current knowledge about age and clinical presentation at diagnosis is sparse even for the most frequent conditions, androgen insensitivity syndrome (AIS), and gonadal dysgenesis. To estimate incidence, prevalence, age at diagnosis, and clinical presentation at diagnosis in 46,XY females. A nationwide study covering all known females with a 46,XY karyotype in Denmark since 1960. The diagnosis of 46,XY disorder of sex development (DSD) was determined by medical record evaluation, data from the Danish National Patient Registry, and genetic testing, if available. A total of 166 females registered as 46,XY females in the Danish Cytogenetic Central Registry were identified. A total of 124 females were classified as having 46,XY DSD, 78 with AIS and 25 with gonadal dysgenesis, whereas the remaining subjects had a variety of different diagnoses. The prevalence of 46,XY females was 6.4 per 100 000 live born females, and for AIS and gonadal dysgenesis, it was 4.1 and 1.5 per 100 000, respectively. Median age at diagnosis was 7.5 years (95% confidence interval, 4.0-13.5; range, 0-34 y) in AIS and 17.0 years (95% confidence interval, 15.5-19.0; range, 0-28 y) in gonadal dysgenesis (P = .001). Clinical presentation was dependent on cause of DSD. The first estimate on prevalence of 46,XY females is 6.4 per 100 000 live born females. The presentation of AIS and gonadal dysgenesis is distinctly different, with AIS being diagnosed during childhood and gonadal dysgenesis during pubertal years. The presenting phenotype is dependent on the cause of 46,XY DSD.

After two decades of civil war, South Sudan has limited published data on HIV prevalence and behavioral determinants of HIV infection risk. A surge in HIV/AIDS prevalence is a real concern for this new country with limited access to medical or HIV preventive services, and low education and literacy levels. We present findings from the first bio-behavioral surveillance survey conducted within the Sudan People's Liberation Army (SPLA). A cross-sectional survey of 1,149 randomly selected soldiers from thirteen SPLA bases was conducted in two phases: July to August 2010 and April to May 2012. Consenting participants received HIV rapid tests, pre- and post-test counseling, and a personal interview. Demographics, knowledge, attitudes, and behaviors, including sexual behavior, alcohol use, and mental health were assessed using computer-assisted interviews. The final sample included 1,063 survey participants (96.7% male). Education levels within the SPLA are low; only 16.4% attended school beyond the primary level. The overall HIV prevalence in the sample was 5.0% (95% confidence interval [CI]: 3.6-6.9). High-risk behaviors (e.g., multiple or concurrent sexual partners, heavy alcohol use, low condom use) were noted among SPLA members. High levels of HIV stigma were identified: 90.6% (n = 916) responded with one or more negative beliefs towards PLHIV, and 60.3% thought a healthy-looking person with HIV should not be allowed to remain in the SPLA. Results from this first evaluation of risk behaviors and HIV prevalence among the SPLA highlight high-risk behaviors that may contribute to the spread of HIV. Understanding potential comorbid conditions will be critical to designing strategies to reduce HIV risk. This survey represents the first steps in understanding the HIV epidemic within the SPLA context.

Neck pain is a musculoskeletal condition with high prevalence that may affect the physical, social, and psychological aspects of the individual, contributing to the increase in costs in society and business. To determine the prevalence of neck pain and associated factors in a population-based sample of adults aged 20 and more. Cross-sectional study based on a population survey. A total number of 600 individuals were interviewed in their homes, and the following data were collected: (1) participant characteristics (demographic, socioeconomic, and work-related aspects) using a pre-coded questionnaire; (2) physical activity level using the IPAQ; and (3) musculoskeletal symptoms using the Nordic questionnaire. Descriptive, bivariate, and Poisson regression analyses were performed. The prevalence of neck pain was 20.3% (95% CI 17.3-23.7). The adjusted analyses showed that individuals who were widowers or separated (PR=2.26; 1.42-5.88), had a low income (PR=1.32; 1.22-6.27) or low educational level (PR=1.83; 1.02-5.26), worked while sitting and leaning (PR=1.55; 1.08-2.40), and who reported having two or more diseases (PR=1.71; 1.55-6.31) remained associated with neck pain. This study reveals the high prevalence of neck pain and remarkable association with widowed/separated people who have low income and low educational level, who perform their occupational activities in sitting and leaning positions, and who reported having two or more diseases. Knowledge of these risk factors will contribute to the development of forms of assistance in which neck pain can be prevented and better managed.

Temperature, precipitation and humidity are known to be important factors for the development of schistosome parasites as well as their intermediate snail hosts. Climate therefore plays an important role in determining the geographical distribution of schistosomiasis and it is expected that climate change will alter distribution and transmission patterns. Reliable predictions of distribution changes and likely transmission scenarios are key to efficient schistosomiasis intervention-planning. However, it is often difficult to assess the direction and magnitude of the impact on schistosomiasis induced by climate change, as well as the temporal transferability and predictive accuracy of the models, as prevalence data is often only available from one point in time. We evaluated potential climate-induced changes on the geographical distribution of schistosomiasis in Zimbabwe using prevalence data from two points in time, 29 years apart; to our knowledge, this is the first study investigating this over such a long time period. We applied historical weather data and matched prevalence data of two schistosome species (Schistosoma haematobium and S. mansoni). For each time period studied, a Bayesian geostatistical model was fitted to a range of climatic, environmental and other potential risk factors to identify significant predictors that could help us to obtain spatially explicit schistosomiasis risk estimates for Zimbabwe. The observed general downward trend in schistosomiasis prevalence for Zimbabwe from 1981 and the period preceding a survey and control campaign in 2010 parallels a shift towards a drier and warmer climate. However, a statistically significant relationship between climate change and the change in prevalence could not be established.

The prevalence of male homosexuality is difficult to elicit considering the sensitivity of one's sexual orientation. The Global Online Sexuality Survey (GOSS) is an online epidemiologic study of male and female sexuality. The online nature of GOSS allows more confidentiality and wider geographic reach, particularly important in investigating sexual issues within the more conservative societies. This study aims to determine the prevalence of male homosexuality among Internet users in the Arabic-speaking Middle East and the unique characteristics of this subset of the population. Prevalence of male homosexuality. In the year 2010, GOSS was offered to Arabic-speaking web surfers above 18 years of age in the Middle East. Potential participants were invited via advertising on Facebook®. Invitations were dispatched randomly with the exception of geographic region and age, regardless web surfing preferences. GOSS relied in part on validated questionnaires such as the International Index of Erectile Function, as well on other nonvalidated questions. 17.1% reported desire toward the same sex, of whom 5.6% had homosexual encounters, mostly in the form of external stimulation rather than intercourse, and exclusively undercover. An overwhelming majority was ego-dystonic (78.2%). This is--to our knowledge--the first online survey to address the prevalence of homosexual orientation and practice in the Middle East, discriminating desire from practice, ego-syntonic from ego-dystonic, and investigating the pattern of practice. Homosexual desire is present in the Middle East as it is around the world, and homosexual encounters are as prevalent. Yet, the undercover and ego-dystonic states prevail. © 2014 International Society for Sexual Medicine.

A cross sectional study was conducted in Moroto and Bukedea districts of Uganda from May to September 2013 to determine the prevalence and risk factors of Echinococcus granulosus infection in dogs. Fresh dog faecal samples were collected, preserved in 70 % ethanol, and later screened for presence of taeniid eggs using zinc chloride floatation method. Positive samples were confirmed by a copro-PCR (polymerase chain reaction) for E. granulosus using NADH dehydrogenase sub-unit 1 gene (NADH1) as a target molecular marker. Structured questionnaires and focus group discussions were used to collect quantitative and qualitative data for risk factor identification. Study sub-counties were selected by simple random sampling. Overall apparent prevalence of taeniid infection in dogs of 14.9 % (39/261, confidence interval 10.6-19.2) in both districts was recorded using the faecal floatation test. The sensitivity of the faecal floatation test was found to be 78 % (25/32), while the specificity was 93 % (215/229). Copro-PCR results revealed a true prevalence of 14.4 % (9.91-19.0, 95 % CI) in dogs in Moroto district and 7.4 % (2.14-12.60, 95 % CI) in Bukedea district. The overall true prevalence of cystic echinococcosis (CE) was 12.2 % (8.70-15.76, 95 % CI) in both districts. The major risk factors identified using logistic regression were uncontrolled access of dogs to animal slaughter facilities, higher cattle herd sizes and lack of knowledge about the disease. It was recommended that restricting dog access to infected tissues and public health education about epidemiology of CE should be done.

There is a knowledge gap in primary school teachers that affects their ability to detect attention deficit hyperactivity disorder (ADHD). This study measured primary school teachers' knowledge about ADHD, and implemented a training programme to improve early detection of ADHD. The prevalence and risk factors of ADHD were also studied. The training programme was implemented through a 2-day workshop for 39 primary school teachers who completed a validated Arabic version of the ADHD Rating Scale for 873 primary school children. The children's parents completed the questionnaire to explore ADHD risk factors. The teachers' pre-training knowledge scores of ADHD ranged from 17.9 to 46.2%. Post-training, their scores improved significantly to 69.2-94.9%. Prevalence rate of ADHD was 12.60%. On logistic regression, independent predictors of ADHD were female gender, unemployed fathers and rural residence. In conclusion, ADHD is a significant health problem among primary school children in Mansoura, Egypt. Efforts should be made to improve teachers' knowledge about ADHD and control modifiable risk factors.

herpes simplex virus type 2 (HSV-2) and human papillomavirus (HPV) are the most frequent sexually transmitted infections (STI) among college students 18-24 years old. Educational interventions for STI prevention can help to decrease viral STI prevalence among students. to know the change in knowledge, perception of risk and sexual behavior among 182 students of the Autonomous University of the State of Morelos. a community intervention trial (before-after) was carried out, using brochures for prevention of HSV-2 and HPV, including information about these STI, with emphasis on the risk factors identified in students of the same university. we found a change in the perception of STI risk during the intervention (56.5 before vs. 67.7% after intervention), possibly the brochures assisted students to learn more about their own risk behaviors. Likewise, there was an increase in knowledge in both HPV and HSV-2. it is necessary to increase the sample size in future interventions to assess further the change in knowledge, sexual behaviors and the prevalence of infections.

Several studies have shown that Alaska Native people have higher smoking prevalence than non-Natives. However, no population-based studies have explored whether smoking-related knowledge, attitudes, and behaviors also differ among Alaska Native people and non-Natives. We compared current smoking prevalence and smoking-related knowledge, attitudes, and behavior of Alaska Native adults living in the state of Alaska with non-Natives. We used Alaska Behavioral Risk Factor Surveillance System data for 1996 to 2010 to compare smoking prevalence, consumption, and cessation- and second-hand smoke-related knowledge, attitudes, and behaviors among self-identified Alaska Native people and non-Natives. Current smoking prevalence was 41% (95% CI: 37.9%-44.4%) among Alaska Native people compared with 17.1% (95% CI: 15.9%-18.4%) among non-Natives. Among current every day smokers, Alaska Natives were much more likely to smoke less than 10 cigarettes per day (OR = 5.0, 95% CI: 2.6-9.6) than non-Natives. Compared with non-Native smokers, Alaska Native smokers were as likely to have made a past year quit attempt (OR = 1.4, 95% CI: 0.9-2.1), but the attempt was less likely to be successful (OR = 0.5, 95% CI: 0.2-0.9). Among current smokers, Alaska Natives were more likely to believe second-hand smoke (SHS) was very harmful (OR = 4.5, 95% CI: 2.8-7.2), to believe that smoking should not be allowed in indoor work areas (OR = 1.9, 95% CI: 1.1-3.1) or in restaurants (OR = 4.2, 95% CI: 2.5-6.9), to have a home smoking ban (OR = 2.5, 95% CI: 1.6-3.9), and to have no home exposure to SHS in the past 30 days (OR = 2.3, 95% CI: 1.5-3.6) than non-Natives. Although a disparity in current smoking exists, Alaska Native people have smoking-related knowledge, attitudes, and behaviors that are encouraging for reducing the burden of smoking in this population. Programs should support efforts to promote cessation, prevent relapse, and establish smoke-free environments.

Genesis of Prolactinomas: Studies Using Estrogen-Treated Animals

Sarkar, Dipak K.

2010-01-01

Prolactin-secreting adenomas (prolactinomas) are the most prevalent form of pituitary tumors in humans. Our knowledge of the formation of these tumors is limited. Experimental work in animal has uncovered that estradiol exposure leads to prolactinoma formation via orchestrated events involving dopamine D2 receptors, transforming growth factor-β (TGF-β) isoforms and their receptors, as well as factors secondary to TGF-β action. Additionally, these studies determined that TGF-β and b-FGF interact to facilitate the communication between lactotropes and folliculo-stellate cells that is necessary for the mitogenic action of estradiol. The downstream signaling that governs lactotropic cell proliferation involves activation of the MAP kinase p44/42-dependent pathway. PMID:16809921

Burn-related injuries are prevalent worldwide. Caregiver first aid can mitigate the devastating effects of paediatric burn injuries. Our aim was to assess knowledge of paediatric burns first aid among caregivers and determine whether knowledge levels can be raised following a short educational intervention. Over a 13-week period we surveyed 274 caregivers at the children's emergency department of KK Women's and Children's Hospital. The questionnaire assessed caregiver demographics and knowledge of burn first aid pre-intervention. There was an educational interlude during which the moderator educated the caregiver using a simple pictorial guide. The survey resumed thereafter and the post-intervention questions were completed. Of the 274 surveys conducted, 272 complete responses were obtained. We found a substantial and statistically significant increase in knowledge of caregivers immediately following the intervention. Two statistically significant predictors of adequate post-interventional scores were the caregivers' highest educational level and their total score in the pre-interventional assessment. Caregivers who scored well in the post-intervention questionnaire relied on school (p=0.013) and the Internet (p=0.130) as sources of information on burns first aid. Caregivers without prior personal experience with burns tended to fare better in the post-interventional survey. Our study shows it is possible to correct knowledge gaps in the immediate period through a simple pictorial guide. Our study also identified a structure for a focused national educational campaign.

Prevalence of autism in mainland China, Hong Kong and Taiwan: a systematic review and meta-analysis

PubMed Central

2013-01-01

Background The prevalence of autism spectrum conditions (ASC) is 1% in developed countries, but little data are available from mainland China, Hong Kong and Taiwan. This study synthesizes evidence relating to the prevalence of ASC in these areas and assesses the effects of research methodology on prevalence estimates. Methods Systematic literature searches were conducted in PubMed, Web of Knowledge, China Web of Knowledge and Weipu databases, as well as relevant papers published from 1987 to 2011, reporting prevalence estimates of ASC or childhood autism in mainland China, Hong Kong and Taiwan. Summary estimates of prevalence were calculated with a random effects model. The effects of research methodology on the prevalence estimates were assessed using a meta-regression model. Results There were 25 studies eligible for review, 18 of which were suitable for inclusion in a meta-analysis. Pooled prevalence of childhood autism was 11.8 per 10,000 individuals (95% confidence interval (CI): 8.2, 15.3) in mainland China. Pooled prevalence of ASC was 26.6 per 10,000 (95% CI: 18.5, 34.6) in three areas. Substantial heterogeneity was identified between studies (I2>75%). The prevalence estimate of childhood autism was most strongly associated with the choice of screening instrument. After adjustment for age group, the odds ratio for prevalence estimates when using the Autism Behavior Checklist (ABC) as the screening instrument compared with those using the Clancy Autism Behavior Scale (CABS) was 0.29 (95% CI: 0.12, 0.69), and 1.79 (95% CI: 0.70, 4.55; P= 0.20) when using the Checklist for Autism in Toddlers (CHAT) compared to the CABS. Conclusions The available studies investigating the prevalence of ASC in China, Hong Kong and Taiwan have focused mainly on childhood autism rather than the whole spectrum. The prevalence estimates are lower than estimates from developed countries. Studies using more recently developed screening instruments reported higher prevalence than older ones. However, available studies have methodological weaknesses and therefore these results lack comparability with those from developed countries. Our findings indicate a potential under-diagnosis and under-detection of ASC in mainland China, Hong Kong and Taiwan, and a need to adopt more advanced methods for research of ASC in these areas.

Understanding how evolution of antimicrobial resistance increases resistance to other drugs is a challenge of profound importance. By combining experimental evolution and genome sequencing of 63 laboratory-evolved lines, we charted a map of cross-resistance interactions between antibiotics in Escherichia coli, and explored the driving evolutionary principles. Here, we show that (1) convergent molecular evolution is prevalent across antibiotic treatments, (2) resistance conferring mutations simultaneously enhance sensitivity to many other drugs and (3) 27% of the accumulated mutations generate proteins with compromised activities, suggesting that antibiotic adaptation can partly be achieved without gain of novel function. By using knowledge on antibiotic properties, we examined the determinants of cross-resistance and identified chemogenomic profile similarity between antibiotics as the strongest predictor. In contrast, cross-resistance between two antibiotics is independent of whether they show synergistic effects in combination. These results have important implications on the development of novel antimicrobial strategies. PMID:25000950

Exploration of the integration of care for persons with a traumatic brain injury using social network analysis methodology.

Integration is a popular strategy to increase the quality of care within systems of care. However, there is no common language, approach or tool allowing for a valid description, comparison and evaluation of integrated care. Social network analysis could be a viable methodology to provide an objective picture of integrated networks. To illustrate social network analysis use in the context of systems of care for traumatic brain injury. We surveyed members of a network using a validated questionnaire to determine the links between them. We determined the density, centrality, multiplexity, and quality of the links reported. The network was described as moderately dense (0.6), the most prevalent link was knowledge, and four organisation members of a consortium were central to the network. Social network analysis allowed us to create a graphic representation of the network. Social network analysis is a useful methodology to objectively characterise integrated networks.

Inherited chromosomally integrated human herpesvirus-6 (iciHHV-6) results in the germ-line transmission of the HHV-6 genome. Every somatic cell of iciHHV-6+ individuals contains the HHV-6 genome integrated in the telomere of chromosomes. Whether having iciHHV-6 predisposes humans to diseases remains undefined. DNA from 19,597 participants between 40 and 69 years of age were analyzed by quantitative PCR (qPCR) for the presence of iciHHV-6. Telomere lengths were determined by qPCR. Medical records, hematological, biochemical, and anthropometric measurements and telomere lengths were compared between iciHHV-6+ and iciHHV-6- subjects. The prevalence of iciHHV-6 was 0.58%. Two-way ANOVA with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on continuous outcomes. Two-way logistic regression with a Holm-Bonferroni correction was used to determine the effects of iciHHV6, sex, and their interaction on disease prevalence. Of 50 diseases monitored, a single one, angina pectoris, is significantly elevated (3.3×) in iciHHV-6+ individuals relative to iciHHV-6- subjects (P = 0.017; 95% CI, 1.73-6.35). When adjusted for potential confounding factors (age, body mass index, percent body fat, and systolic blood pressure), the prevalence of angina remained three times greater in iciHHV-6+ subjects (P = 0.015; 95%CI, 1.23-7.15). Analyses of telomere lengths between iciHHV-6- without angina, iciHHV-6- with angina, and iciHHV-6+ with angina indicate that iciHHV-6+ with angina have shorter telomeres than age-matched iciHHV-6- subjects (P = 0.006). Our study represents, to our knowledge, the first large-scale analysis of disease association with iciHHV-6. Our results are consistent with iciHHV-6 representing a risk factor for the development of angina.

Objectives. We sought to improve public health surveillance by using a geographic analysis of emergency department (ED) visits to determine local chronic disease prevalence. Methods. Using an all-payer administrative database, we determined the proportion of unique ED patients with diabetes, hypertension, or asthma. We compared these rates to those determined by the New York City Community Health Survey. For diabetes prevalence, we also analyzed the fidelity of longitudinal estimates using logistic regression and determined disease burden within census tracts using geocoded addresses. Results. We identified 4.4 million unique New York City adults visiting an ED between 2009 and 2012. When we compared our emergency sample to survey data, rates of neighborhood diabetes, hypertension, and asthma prevalence were similar (correlation coefficient = 0.86, 0.88, and 0.77, respectively). In addition, our method demonstrated less year-to-year scatter and identified significant variation of disease burden within neighborhoods among census tracts. Conclusions. Our method for determining chronic disease prevalence correlates with a validated health survey and may have higher reliability over time and greater granularity at a local level. Our findings can improve public health surveillance by identifying local variation of disease prevalence. PMID:26180983

Intestinal parasites are the causative agents of common infections responsible for significant public health problems in developing countries and generally linked to lack of sanitation, safe water, and improper hygiene. More than two billion people throughout the world live with unrelenting illness due to intestinal parasitic infections (IPIs). The purposes of this study are to assess knowledge, attitudes, and practices on IPIs and investigate the relationship with prevalence of intestinal parasites among a low-income group of inhabitants from two communities of the Travessão District area, Campos dos Goytacazes, north of Rio de Janeiro State, Brazil. The two communities are known as "Parque Santuário," which is an urban slum with miserable living conditions, and "Arraial," where the socioeconomic and educational levels are better, neither having a sanitary infrastructure with an excreta collection system. Questionnaires revealed that both communities had local and specific codification to denominate the intestinal parasites and present correct knowledge on the theme but ignored some aspects of IPI transmission, with the Arraial population being better informed (p < 0.05). The overall prevalence of IPIs in Parque Santuário (49.7%) was greater than in Arraial (27.2%) (p < 0.001; prevalence ratio/95% confidence interval 1.83/1.50-2.23). This study reports the real IPI situation in the Travessão District and also reinforces the need to continue the investigation on the impact of combined prophylactic methods, educational measures, and socioeconomic and sanitary improvements by governmental authorities and the local popular organization.

Background Bovine Tuberculosis (bTB) is still a serious public health threat in developing countries. The aim of this study is to determine the social and cognitive factors predicting one of the risk behaviours amongst meat handlers in Nigeria, namely, eating Fuku Elegusi. This is the practice of eating the visibly infected parts of the lung in-order to convince customers to buy meat. The study is guided by the health belief model (HBM). Methods This is a cross-sectional study of 349 randomly selected meat handlers in Oko-Oba Abattoir, in Lagos State. Descriptive statistics and multiple logistic regression analysis were employed to determine perceptions and prevalence of risk behaviours and to identify predictors of eating Fuku Elegusi. Results Just over a quarter (28.1%) of the study participants knew that eating Fuku Elegusi could be a source of bTB in humans. The prevalence of eating Fuku Elegusi was found to be 22%. Across all knowledge indicators related to bTB, those who don't eat Fuku Elegusi exhibited better knowledge. Strong predictors of eating Fuku Elegusi were: being male (OR: 2.39, 95% CI: 1.10 to 5.19; p = 0.03), not knowing that eating Fuku Elegusi exposes to bTB (OR: 3.72, 95% CI: 1.69 to 8.22; p = 0.001), and the perception that one cannot sell meat without tasting it (perceived barrier) (OR: 1.35, 95% CI: 1.13 to 1.60; p = 0.001). Lower risk of eating Fuku Elegusi was predicted by perceived susceptibility to bTB due to another risk behaviour, namely, not washing hands after handling meat (OR: 0.78, 95% CI: 0.64 to 0.96; p-value = 0.021). Television and radio were the most acceptable media for TB prevention messages (78.5% and 75.6% respectively). Conclusion Meat handlers in developing countries bear high risk to bTB owing to prevailing social and cognition determinants. Findings were largely consistent with the propositions of HBM.

The study aimed to determine the following among the workforce of the Jaipur Dental College, India: their awareness regarding biomedical (BM) waste management policy and practices, their attitude towards biomedical waste management, and their awareness regarding needle-stick injury and its prevalence among different categories of health care providers. A cross-sectional study was conducted using a questionnaire with closed-ended questions. It was distributed to 144 dentists, nurses, laboratory technicians and Class IV employees (cleaners and maintenance personnel) at Jaipur Dental College. The questionnaire was used to assess their knowledge of biomedical medical waste disposal. The resulting answers were graded and the percentage of correct and incorrect answers for each question from all the participants was obtained. Of the 144 questionnaires, 140 were returned and the answers graded. The results showed that there was a poor level of knowledge and awareness of biomedical waste generation hazards, legislation and management among health care personnel. It was surprising that 36% of the nurses had an extremely poor knowledge of biomedical waste generation and legislation and just 15% of the Class IV employees had an excellent awareness of biomedical waste management practice. It can be concluded from the present study that there are poor levels of knowledge and awareness about BM waste generation hazards, legislation and management among health care personnel in Jaipur Dental College. Regular monitoring and training are required at all levels.

Background and aim Self-medication (SM) is one part of self-care which is known to contribute to primary health care. If practiced appropriately, it has major benefits for the consumers such as self-reliance and decreased expense. However, inappropriate practice can have potential dangers such as incorrect self-diagnosis, dangerous drug-drug interactions, incorrect manner of administration, incorrect dosage, incorrect choice of therapy, masking of a severe disease, and/or risk of dependence and abuse. The main objective of this study was to assess the prevalence and determinants of the self-medication practice (SMP) in Addis Ababa. Methodology A community based cross-sectional study was conducted among selected households in Addis Ababa from April 2016 to May 2016, with a recall period of two months before its conduction. Trained data collectors were employed to collect the data from the 604 sampled participants using pre-tested and validated questionnaires. Result Among the 604 participants involved in this study, 422 (69.9%) were female and 182 (30.1%) were male and there was a mean age of 41.04 (± 13.45) years. The prevalence of SM in this study was 75.5%. The three most frequently reported ailments were headache 117 (25.7%), abdominal pain 59 (12.9%) and cough 54 (11.8%). The two main reasons for SM were mildness of illness 216 (47.4%) and previous knowledge about the drug 106 (23.2%). The two most frequently consumed medications were paracetamol 92 (20.2%) and traditional remedies 73 (16.0%), while drug retail outlets 319 (83.3%) were the main source of drugs. The two most frequently reported source of drug information were health professionals 174 (45.4%) and experience from previous treatment 82 (21.4%). Moreover, there were statistically significant differences among respondents who reported practicing SM based on income and knowledge about appropriate SMP. Conclusion and recommendation Self-medication was practiced with a range of drugs from the conventional paracetamol and NSAIDs to antimicrobials. Being that the practice of SM is inevitable, health authorities and professionals are highly demanded to educate the public not only on the advantages and disadvantages of SM but on its proper use.

This cross-sectional study investigated the prevalence of brucellosis and bovine tuberculosis (BTB) in local cattle and goat breeds of Oromo and Afar pastoralist communities living in two distinct parts around the Awash National Park. A questionnaire survey was carried out to assess information on husbandry, milk consumption habits, and on knowledge-attitude-practice regarding both diseases. Among a total of 771 animals from all sites tested by comparative intradermal tuberculin test (CIDT) none were BTB reactors with the >4mm cut-off. Using the >2mm cut-off, individual apparent prevalence was 0.9% (95%CI: 0.23-3.56%) in cattle and 0.7% (95%CI: 0.12-3.45%) in goats. Herd prevalence in Oromia and Afar sites was 0% and 66.7% respectively in goats and 16.7% and 50% in cattle. Among the 327 animals tested by enzyme linked immunoassay for brucellosis, 4.8% (95%CI: 1.2-17.1%) of cattle and 22.8% (95%CI: 5.98-29.5%) of goats were reactors. Highest individual prevalence of both diseases was found in Afar settlements with brucellosis being as high as 50%. Respondent ethnicity was the only risk factor for brucellosis positivity in goats in the univariable risk factor analysis. Knowledge about the diseases was poor. Raw goat milk was regularly consumed by women and children, putting them at risk for brucellosis. This study highlighted an increased prevalence gradient of BTB and brucellosis from West to East along the study sites with high brucellosis individual prevalence and abortion rates among Afar settlements in particular.

2016-01-01

Healthcare workers, especially those with direct patient contact are amongst professions with the highest rate of workrelated musculoskeletal disorders (WMSDs), physical therapists (PTs) being one of them. Our objective was to review current knowledge relating to the prevalence, risk factors and prevention of WMSDs among PTs. Pubmed, Google Scholar and PEDro databases were searched for terms relating to WMSDs in PTs from inception to 2015. The prevalence of WMSDs among PTs was high, with lifetime prevalence reported as 55-91%, and 12-month prevalence ranges 40-91.3%, and the lower back as the most frequently affected, with estimates of a lifetime prevalence ranging 26-79.6%, and a 12-month prevalence ranging 22-73.1%, followed most often by the neck, upper back and shoulders. The major risk factors for workrelated low back pain (LBP) were: lifting, transferring, repetitive movements, awkward and static postures, physical load, treating a large number of patients in a single day and working while injured. Low back pain seems to be age- and genderrelated with a higher prevalence in females, younger PTs and PTs working in rehabilitation settings. Physical therapists, as a consequence of work-related LBP, may seek treatment, modify their daily living and leisure (lifestyle) activities, use aids and equipment or change their specialty area either within the profession or by leaving it. Skills and knowledge as to correct body mechanics do not prevent work-related injuries. Mechanical aids used for a patient transfer should be adopted by PTs and new strategies should be developed to reduce their WMSDs without compromising the quality of treatment.

1969-01-01

Blood protozoa were first reported from wild birds in 1884. Since then numerous surveys throughout the world have demonstrated their presence in a wide variety of hosts and localities with continuing designations of new species. Taxonomic determinations include parasites in the genera Plasmodium, Haemoproteus, Leucocytozoon, Babesia, Lankesterella and Trypanosoma. Transmission of Plasmodium by mosquitoes was demonstrated with a bird parasite before these insects were proven as vectors of human malaria. All the genera under consideration require an insect vector to complete their life-cycles and susceptible vectors have been demonstrated. Most experimental work on the blood protozoa of birds has been carried on with captive birds. An extensive volume of research has been conducted on Plasmodium because of its close similarity to malaria in man. Field studies that would provide information on the epizootiology of occurrence of these parasites in wild populations have been very limited, mainly confined to single blood film surveys. Such data are inadequate to provide an understanding of true prevalence or incidence or of factual knowledge of their impact on the wild population. Mechanisms for procuring such information are available in some cases and can be developed to fit other situations. Isodiagnosis, inoculation of blood from wild birds into susceptible captive hosts, has revealed a prevalence of over 60 % for Plasmodium in situations where microscope examination of single peripheral blood preparations yielded less than 1 %. Culture of bone marrow collected by biopsy demonstrates high prevalence of trypanosomes even when none are evident from microscopic examination of blood. Often preparations of tissues collected at necropsy reveal Leucocytozoon and Lankesterella when examination of peripheral blood gave no indication of infection. Methods developed by bird ringers provide techniques for obtaining repeat examinations of free-living birds that can yield further pertinent data. The use that has been made of these techniques, beyond the mere procurement of a single blood film, is reviewed from the standpoint of providing knowledge of the epizootiology of the blood protozoa of birds and their further potential is projected.

Cardiovascular disease (CVD) is the leading cause of death throughout the world. Despite its high prevalence, the atherosclerotic process can be slowed and its consequences markedly reduced by preventive measures. The lack of risk factor awareness is a major barrier. We aimed to assess total CV risk, determine the knowledge and awareness regarding CVD, and evaluate the effectiveness of education program in urban population of Turkey. A 24-item questionnaire was used to detect CV risk factors and the awareness of participants about CVD. The feedback data for the education program were collected by either questionnaires or individual interviews with participants. For comparison of total CVD risk in men and women in different age groups, a sample t test was used. The level of statistical significance was set at p < 0.05. The prevalence of hyperlipidemia was established to be 41.3%. Nearly one-quarter of the women and one-third of the men were smokers (p < 0.001). One-quarter of the responders had a history of hypertension (men: 21.5%, women: 18.6%), and one-tenth were diabetic. The high CV risk rate was more pronounced among men (p < 0.01) and those with low socioeconomic level (p < 0.01). Awareness regarding CV risk factors following the educational program increased from 6.6% to 12.7% for high blood pressure, from 3.9% to 9.2% for diabetes mellitus, and from 10.2% to 15.1% for elevated cholesterol levels. All the increases were statistically significant. The educational program significantly increased the awareness of CVD and risk factors. The prevalence of CV risk factors was higher in low socioeconomic level groups. The knowledge and awareness of the risk factors for CVD before the education program was very low in our study group. The awareness of CVD and risk factors significantly increased following our education programs. Copyright © 2013 World Heart Federation (Geneva). Published by Elsevier B.V. All rights reserved.

Pediculosis caused by head lice (Pediculus humanus capitis) infestation is still an important health problem in schoolchildren, especially girls, worldwide, including in Thailand. Although pediculicidal agents effectively kill head lice, the re-infestation rate is still high. Thus, prevention is an important strategy for any sustainable control program. We aimed to develop and evaluate the efficacy of a health education program for increasing knowledge, changing attitudes and promoting preventive practices to reduce prevalence of pediculosis among school girls in Amphoe Muang, Khon Kaen, northeastern Thailand. Six schools were selected using multistage simple randomization and were allocated into intervention or control groups. A total of 267 girls was enrolled from these schools. A "knowledge, attitude and practice" (KAP) questionnaire, consent forms and health education materials were constructed and tested by experts and in one pilot school before the main investigation. Baseline prevalence of adult lice and nits was determined. The health education package was given only to the intervention group. The KAP questionnaire was re-evaluated at two months after intervention. At baseline, the prevalence and intensity of head lice infestation, and the KAP scores did not differ significantly between the two groups. After re-evaluation at two months, the KAP score was significantly greater in the intervention group. A significant decrease of the infestation rate from 59% to 44% was observed in the intervention group, whereas infestation increased in the control group (from 56% to 65%). The incidence of new cases in the intervention group (6.14%) was lower than in the control group (12.62%). These findings indicated that the newly-established health education package is an effective tool for increasing KAP and reducing head lice infestation in school girls. Efforts to combat pediculosis in schoolchildren elsewhere may consider including this, or a similar, health education package in their programs.

Prevalence of Helicobacter pylori infection in Nepal, a low-risk country for gastric cancer, is debatable. To our knowledge, no studies have examined H. pylori virulence factors in Nepal. We determined the prevalence of H. pylori infection by using three different tests, and the genotypes of virulence factors were determined by PCR followed by sequencing. Multilocus sequence typing was used to analyze the population structure of the Nepalese strains. The prevalence of H. pylori infection in dyspeptic patients was 38.4% (56/146), and was significantly related with source of drinking water. In total, 51 strains were isolated and all were cagA-positive. Western-type-cagA (94.1%), cagA pre-EPIYA type with no deletion (92.2%), vacA s1a (74.5%), and m1c (54.9%) were the predominant genotypes. Antral mucosal atrophy levels were significantly higher in patients infected with vacA s1 than in those infected with s2 genotypes (P = 0.03). Several Nepalese strains were H. pylori recombinants with genetic features of South Asian and East Asian genotypes. These included all East-Asian-type-cagA strains, with significantly lesser activity and inflammation in the corpus than the strains of the specific South Asian genotype (P = 0.03 and P = 0.005, respectively). Although the population structure confirmed that most Nepalese strains belonged to the hpAsia2 population, some strains shared hpEurope- and Nepalese-specific components. Nepalese patients infected with strains belonging to hpEurope showed higher inflammation in the antrum than strains from the Nepalese specific population (P = 0.05). These results support that ancestor roots of Kathmandu`s people not only connected with India alone. PMID:26226153

The aim of this study was to determine estimates of the prevalence and social correlates of physical inactivity among university students in 23 low-, middle- and high-income countries. The International Physical Activity Questionnaire was used to collect data from 17,928 undergraduate university students (mean age 20.8, SD = 2.8) from 24 universities in 23 countries. The prevalence of physical inactivity was 41.4 %, ranging from 21.9 % in Kyrgyzstan to 80.6 % in Pakistan. In multivariate logistic regression, older age (22-30 years), studying in a low- or lower middle-income country, skipping breakfast and lack of social support were associated with physical inactivity. In men, being underweight, being overweight or obese, not avoiding fat and cholesterol, not having severe depression symptoms, low beliefs in the health benefits of physical activity, low personal control and knowledge of exercise-heart link, and in women, not trying to eat fibre, low personal mastery and medium personal control were additionally associated with physical inactivity. Four in each ten students are physically inactive, calling for strategic interventions by relevant professionals in higher educational institutions.

To estimate prevalence and identify correlates of age of smoking initiation among adolescents in Africa. Data (n = 16,519) were obtained from nationally representative Global Youth Tobacco Surveys in nine West African countries. Study outcome was adolescents' age of smoking initiation categorized into six groups: ≤7, 8 or 9, 10 or 11, 12 or 13, 14 or 15 and never-smoker. Explanatory variables included sex, parental or peer smoking behavior, exposure to tobacco industry promotions, and knowledge about smoking harm. Weighted multinomial logit models were conducted to determine correlates associated with adolescents' age of smoking initiation. Age of smoking initiation was as early as ≤7 years; prevalence estimates ranged from 0.7 % in Ghana at 10 or 11 years age to 9.6 % in Cote d'Ivoire at 12 or 13 years age. Males, exposures to parental or peer smoking, and industry promotions were identified as significant correlates. West African policymakers should adopt a preventive approach consistent with the World Health Organization Framework Convention on Tobacco Control to prevent an adolescent from initiating smoking and developing into future regular smokers.

Microbial endoliths, which inhabit interior pores of rocks, skeletons and coral, are ubiquitous in terrestrial and marine environments. In the present study, various colored layers stratified the endolithic environment within the skeleton of Isopora palifera; however, there was a distinct green-pigmented layer in the skeleton (beneath the living coral tissue). To characterize diversity of endolithic microorganisms, 16S ribosomal RNA gene amplicon pyrosequencing was used to investigate bacterial communities in the green layer of Isopora palifera coral colonies retrieved fromGreen Island, Taiwan. The dominant bacterial group in the green layer belonged to the bacterial phylum Chlorobi, green sulphur bacteria capable of anoxygenic photosynthesis and nitrogen fixation. Specifically, bacteria of the genus Prosthecochloris were dominant in this green layer. To our knowledge, this is the first study to provide a detailed profile of endolithic bacteria in coral and to determine prevalence of Prosthecochloris in the green layer. Based on our findings, we infer that these bacteria may have an important functional role in the coral holobiont in the nutrient-limited coral reef ecosystem.

Despite the use of competency-based frameworks to evaluate physicians, the role of competency-based objectives in undergraduate medical education remains uncertain. By use of an audit methodology, we sought to determine how the six Accreditation Council for Graduate Medical Education (ACGME) competencies, conceptualized as educational domains, would map onto an undergraduate medical curriculum. Standardized audit forms listing required activities were provided to course directors, who were then asked to indicate which of the domains were represented in each activity. Descriptive statistics were calculated. Of 1,500 activities, there was a mean of 2.13 domains per activity. Medical Knowledge was the most prevalent (44%), followed by Patient Care (20%), Interpersonal and Communication Skills (12%), Professionalism (9%), Systems-Based Practice (8%), and Practice-Based Learning and Improvement (7%). There was considerable variation by year and course. The domains provide a useful framework for organizing didactic components. Faculty can also consider activities in light of the domains, providing a vocabulary for instituting curricular change and innovation.

Childhood visual impairment (CVI) has not been given due attention. Knowledge of CVI is important in planning preventive measures. The aim of this study was determine the prevalence, etiology and the factors associated with childhood visual impairment among the children attending the eye clinic in Mulago National Referral Hospital. This was a cross sectional hospital based study among 318 children attending the Mulago Hospital eye clinic between January 2015 to March 2015. Ocular and general history was taken and patient examination done. The data generated was entered by Epidata and analyzed by STATA 12. The prevalence of CVI was 42.14%, 134 patients with 49 patients (15.41%) having moderate visual impairment, 45 patients (14.15%) having severe visual impairment and 40 patients (12.58%) presenting with blindness. Significant predictors included; increasing age, delayed developmental milestones and having abnormal corneal, refractive and fundus findings. There is a high burden of visual impairment among children in Uganda. It is vital to screen all the children presenting to hospital for visual impairment. Majority of the causes of the visual impairment are preventable.

Geometric reasoning

1987-01-01

Cognitive robot systems are ones in which sensing and representation occur, from which task plans and tactics are determined. Such a robot system accomplishes a task after being told what to do, but determines for itself how to do it. Cognition is required when the work environment is uncontrolled, when contingencies are prevalent, or when task complexity is large; it is useful in any robotic mission. A number of distinguishing features can be associated with cognitive robotics, and one emphasized here is the role of artificial intelligence in knowledge representation and in planning. While space telerobotics may elude some of the problems driving cognitive robotics, it shares many of the same demands, and it can be assumed that capabilities developed for cognitive robotics can be employed advantageously for telerobotics in general. The top level problem is task planning, and it is appropriate to introduce a hierarchical view of control. Presented with certain mission objectives, the system must generate plans (typically) at the strategic, tactical, and reflexive levels. The structure by which knowledge is used to construct and update these plans endows the system with its cognitive attributes, and with the ability to deal with contingencies, changes, unknowns, and so on. Issues of representation and reasoning which are absolutely fundamental to robot manipulation, decisions based upon geometry, are discussed here, not AI task planning per se.

Attention deficit hyperactivity disorder (ADHD) is the most common neurobehavioural disorder among schoolchildren. It may persist into adulthood and affect performance in the academic, social, occupational and familial spheres, and increase the use and abuse of alcohol and psychoactive substances and the risk of having an accident. Its prevalence throughout the world varies widely and further knowledge about this situation would be valuable for the development of policies in the sector of education. The aim of this research was to determine the prevalence of ADHD and its distribution according to subtypes in schoolchildren from Sabaneta, Antioquia, Colombia, in 2001. The analysis involved a cross-sectional descriptive study using a representative randomised multistage sample (which was proportional to the size of the groups) of schoolchildren between 4 and 17 years old. Measurement was performed in two stages, first by application of a screening form according to DSM IV criteria, and later a structured interview, Conners' and Intelligence tests. Prevalence was found to be 20.4% and 15.8% if only children with an intelligence quotient of 80 or above were considered. The combined subtype was the most frequent, with 9.6%. In public schools it was 16.2%, private 15.3%, age group from 7-11 years 16.9%, 12-17 years old 14.2%, males 20.9%, females 10.1%, low 14.7%, medium 17.4% and high socioeconomic level 10.7%, with a male to female prevalence ratio of 3.88 to 1. Prevalence of ADHD in the school population in a municipality in the Metropolitan Area of Medellin, Colombia, is high. The most frequent subtype was the combined type, which was predominant in males, had repercussions on academic performance and low proportions of pharmacological interventions for the disorder (15%). Programmes must be developed for the detection of this problem and subsequent intervention in the school population.

Stroke is a major chronic disease and a common cause of adult disability and mortality. Although there are many known risk factors for stroke, lower income is not one that is often discussed. To determine the unadjusted and adjusted association of income distribution on the prevalence of stroke in Saskatchewan, Canada. Information was collected from the Canadian Community Health Survey conducted by Statistics Canada for 2000-2008. In total, 178 variables were analysed for their association with stroke. Prior to statistical adjustment, stroke was seven times more common for lower income residents than higher income residents. After statistical adjustment, only four covariates were independently associated with stroke prevalence, including having high blood pressure (odds ratio (OR) = 2.62; 95% confidence interval (CI) = 2.12-3.24), having a household income below CAD$30,000 per year (OR = 2.49; 95% CI = 1.88-3.29), being a daily smoker (OR = 1.36; 95% CI = 1.16-1.58) and being physically inactive (OR = 1.27; 95% CI = 1.13-1.43). After statistical adjustment, there were five covariates independently associated with high blood pressure prevalence, including having a household income below CAD$30,000 per year (OR = 1.52; 95% CI = 1.41-1.63). After statistical adjustment, there were five covariates independently associated with daily smoking prevalence, including having a household income below CAD$30,000 per year (OR = 1.29; 95% CI = 1.25-1.33). Knowledge of disparities in the prevalence, severity, disability and mortality of stroke is critically important to medical and public health professionals. Our study found that income distribution was strongly associated with stroke, its main disease intermediary - high blood pressure - and its main risk factor - smoking. As such, income is an important variable worthy of public debate as a modifiable risk factor for stroke.

This could bring them into closer contact with humans and increase the risk of zoonotic pathogen transmission. To describe the prevalence and diversity of Cryptosporidium spp., microsporidia and Giardia intestinalis in orangutans at seven sites on Sumatra and Kalimantan, and to evaluate the impact of orangutans' habituation and location on the occurrence of these zoonotic protists. The overall prevalence of parasites in 298 examined animals was 11.1%. The most prevalent microsporidia was Encephalitozoon cuniculi genotype II, found in 21 animals (7.0%). Enterocytozoon bieneusi genotype D (n = 5) and novel genotype Pongo 2 were detected only in six individuals (2.0%). To the best of our knowledge, this is the first report of these parasites in orangutans. Eight animals were positive for Cryptosporidium spp. (2.7%), including C. parvum (n = 2) and C. muris (n = 6). Giardia intestinalis assemblage B, subtype MB6, was identified in a single individual. While no significant differences between the different human contact level groups (p = 0.479-0.670) or between the different islands (p = 0.992) were reported in case of E. bieneusi or E. cuniculi, Cryptosporidium spp. was significantly less frequently detected in wild individuals (p < 2×10-16) and was significantly more prevalent in orangutans on Kalimantan than on Sumatra (p < 2×10-16). Our results revealed that wild orangutans are significantly less frequently infected by Cryptosporidium spp. than captive and semi-wild animals. In addition, this parasite was more frequently detected at localities on Kalimantan. In contrast, we did not detect any significant difference in the prevalence of microsporidia between the studied groups of animals. The sources and transmission modes of infections were not determined, as this would require repeated sampling of individuals, examination of water sources, and sampling of humans and animals sharing the habitat with orangutans.

Background Travel to foreign countries involves the risk of becoming a carrier of antibiotic-resistant bacteria, especially when the destination is a country with a high prevalence of this type of bacteria. Aim and methods The aim of this study was to learn about the knowledge of antibiotic resistance, and the behaviour and risk-taking among travellers, who had become carriers of extended spectrum beta-lactamases (ESBL)-producing bacteria during travel to a high-prevalence country. A modified version of grounded theory was used to analyse 15 open interviews. Results The analysis resulted in a core category: A need for knowledge to avoid risk-taking. Before the journey, the participants did not perceive there to be any risk of becoming a carrier of antibiotic- resistant bacteria. The low level of knowledge of antibiotic-resistant bacteria and transmission routes influenced their behaviour and risk-taking during their journey, resulting in them exposing themselves to risk situations. After their trip, the majority did not believe that their personal risk behaviour could have caused them to become carriers of ESBL. Conclusion The participants’ lack of knowledge of antibiotic-resistant bacteria resulted in unconscious risk-taking during their journey, which may have resulted in becoming carriers of ESBL-producing bacteria.

The present study examined the knowledge of Alzheimer's disease and correlates of the disease knowledge among Vietnamese Americans. Cross-sectional survey interviews were conducted with 95 middle-aged and older Vietnamese Americans. Vietnamese Americans showed limited knowledge about Alzheimer's disease. Normalization of Alzheimer's disease in old age was prevalent. They lacked knowledge about treatment and cure of Alzheimer's disease. Those who reside longer in the U.S. and are more exposed to Alzheimer's disease are likely to have higher levels of Alzheimer's disease knowledge. Our study identified current Alzheimer's disease knowledge level and status, and areas of misconceptions and knowledge gaps among Vietnamese Americans, calling for urgent needs for educational outreach to improve knowledge about Alzheimer's disease among Vietnamese Americans. Information about who can be more or less knowledgeable about Alzheimer's disease can be used to strategize and tailor outreach efforts for different segments of the Vietnamese American population.

Iraqi Kurdistan region is one of the areas where female genital mutilation is reportedly widely practiced but inadequately studied. The aim of this study was to determine (i) the prevalence of female genital mutilation among Muslim Kurdish women in Erbil city, (ii) the patterns and types of female genital mutilation, (iii) the factors associated with this practice and (iv) women's knowledge and attitudes towards this practice. A cross-sectional study was conducted in the primary health care centers and the Maternity Teaching Hospital in Erbil city, involving 1987 women aged 15-49 years. Data were obtained about female genital mutilation status and knowledge and perception towards this practice. The participants were clinically examined to verify the self-reported female genital mutilation status. The self-reported prevalence of female genital mutilation was 70.3%, while it was 58.6% according to clinical examination of the women's genitalia. The most common type of female genital mutilation was type I (99.6%) and the most common age at which mutilation was performed was 4-7 years (60.2%). This practice was mostly performed by traditional birth attendants (72.5%). Only 6.4% of mutilated women reported having complications after mutilation, most commonly bleeding (3.6%). The practice was more reported among housewives (OR = 3.3), those women whose mothers were mutilated (OR = 15.1) or with unknown mutilation status (OR = 7.3) and those women whose fathers were illiterate (OR = 1.4) or could only read and write (OR = 1.6). The common reasons for practicing female genital mutilation were cultural tradition (46.7%) and dictate of religion (38.9%). Only 30% of the participants were aware about the health consequences of female genital mutilation. More than one third (36.6%) of the women support the practice and 34.5% have intention to mutilate their daughters. Prevalence of female genital mutilation among Muslim Kurdish women in Erbil city is very high; although, most cases are of type I. There is clear lack of knowledge about the health consequences of female genital mutilation and a relatively important segment of women support this practice. Custom or tradition and dictate of religion are the main reasons for this practice that need further in-depth exploration.

Inflammatory bowel disease (IBD) is the term used for a group of diseases with yet unknown etiology, prevalence of which is increasing almost everywhere in the world. The disease was almost non-existent four decades ago in the east, including the middle-east, while now a days it is seen more and more. In addition to the increasing prevalence, our knowledge about its pathogenesis, clinical course, diagnosis, and treatment has changed dramatically over the past couple of decades. This has changed our concept of this group of diseases, their diagnosis, treatment, and treatment goals. Considering the vast literature on the subject, it is timely to review major topics in IBD with a look on the regional progress and knowledge as well. This essay is aimed to cover this task.

Use a presurvey of primary care providers (PCPs) enrolled in a continuing medical education (CME) program on headache management to ascertain their existing knowledge, attitudes, and beliefs regarding migraine and use a postsurvey to determine the extent to which the CME program has brought participant knowledge, attitudes, and skills closer to conformance with best evidence. Migraine is a common and debilitating condition, which PCPs may not always manage satisfactorily. In an effort to improve management, the American Headache Society has developed a CME program called BRAINSTORM that encourages PCPs to adopt the US Headache Consortium Guidelines for headache care. A 20-item questionnaire was developed that covered the essential elements of migraine care. The questionnaire was administered before and after a BRAINSTORM presentation to 254 consenting primary care clinicians attending a medical meeting at 1 of 6 sites. A control group of 112 comparable physicians who did not attend the presentation completed the same questionnaire. Prepresentation scores of attendees were compared to scores of nonattendees to assess the generalizability of results. Prepresentation scores on selected questions were used to assess participant baseline knowledge, attitudes, and beliefs. Pre- and postpresentation scores for attendees at all sites were compared using the Mantel-Haenszel statistic to assess the effectiveness of the BRAINSTORM CME. Pre- and postpresentation scores were compared by site using the Breslow-Day test to evaluate any differential impact based on CME location. Prepresentation scores of attendees and nonattendees were found to be similar. No significant difference in performance was noted across sites. A chi-square analysis revealed a statistically significant difference between pre- and postpresentation scores for 16 of the test's 20 questions. In the pretest, all participants scored <66% on 2 questions related to prevalence, impact, and pathophysiology of migraine, 2 questions pertaining to history taking/physical examination, and 3 migraine management questions. Attendee scores improved to >66% posttest on all except 2 questions related to prevalence, impact, and pathophysiology of migraine. Our results indicate that PCPs need to acquire greater understanding about the epidemiology and pathophysiology of migraine and may require guidance in history taking and physical examination of migraine patients. Improvement in scores posttest confirms that the BRAINSTORM program has a significant immediate impact on the knowledge, beliefs, and attitudes of participants. The program could be strengthened to improve emphasis in some areas where posttest scores showed no improvement.

To evaluate the prevalence of vitamin supplementation in Thai children aged 1-5 years at Queen Sirikit National Institute of Child Health (QSNICH), parental knowledge of vitamins, practices, and related factors such as nutritional status in vitamin supplementation. A cross-sectional study was performed at the Well Child Clinic, QSNICH, from 1-31 May 2005. Five hundred parents of young children, aged 1-5 years were interviewed by using the questionnaire to obtain information regarding knowledge and practices of vitamin supplementation. Weight and length/height were measured and nutritional status was assessed using the Thai growth reference. The relationships among vitamin supplement, nutritional status, and other related factors were analyzed using Chi-square test. The p-value < 0.05 was considered statistically significant. Prevalence of vitamin supplementation was 76%, including vitamin C 62%, multi-vitamin (MTV) 35%, and cod-liver oil 20%. Regarding parental knowledge of vitamins, 57% of them knew the health benefits but 74% did not know the toxic effects of vitamins. The reasons for vitamin supplementation were poor feeding 63%, under-weight 23% and unhealthy status 14%. Vitamins were obtained from over-the-counter 59%, health services 40%, and friends 1%. Vitamin supplementation was significantly higher in children over 2 years of age, whose parents knew the benefits of vitamins, and in those children with malnutrition. The prevalence of vitamin supplementation was high in malnourished children, over 2 years of age whose parents had knowledge about benefits of vitamins. Parents should be warned about the dangers of high dose of vitamin consumption.

Non communicable diseases are currently a major health challenge facing humanity. Nyeri County has one of the highest diabetes prevalence in Kenya (12.6%), compared to the country's prevalence of 5.6%. The purpose of the study was to document; diabetes knowledge, medicinal plants and demand for the services of traditional medicine practitioners, in the management and treatment of diabetes. A cross-sectional study was carried out in the six constituencies in Nyeri, using pre-tested semi-structured questionnaires. Thirty practicing traditional medicine practitioners were purposively selected for the study. Field observation and identification was carried out on all plants that were cited during the interview. Plant samples were collected and voucher specimen deposited in the University of Nairobi Herbarium in the - School of Biological Sciences. The study revealed 30 plant species in 28 genera and 23 families that are used by the traditional medicine practitioners to treat and manage diabetes. Demand for traditional medicine practitioners' services in the treatment of diabetes is low and often occurs when conventional drugs fail. Interaction with the TMPs unveiled significant diversity of potential anti diabetic medicinal plants and in-depth ethnobotanical knowledge that they possessed. Preference for traditional herbal medicine was low despite wide ethnobotanical knowledge in the face of high prevalence of diabetes in the locality. The findings form the basis of pharmacological studies for standardization of the documented ethnomedicine used in the treatment and management of diabetes in the study area.

Excessive sodium intake is a key modifiable risk factor for hypertension and cardiovascular disease. Although 95% of U.S. adults exceed intake recommendations, knowledge is limited regarding whether doctor or health professional advice motivates patients to reduce intake. Our objectives were to describe the prevalence and determinants of taking action to reduce sodium, and to test whether receiving advice was associated with action. Analyses, conducted in 2014, used data from the 2013 Behavioral Risk Factor Surveillance System, a state-based telephone survey representative of non-institutionalized adults. Respondents (n=173,778) from 26 states, the District of Columbia, and Puerto Rico used the new optional sodium module. We estimated prevalence ratios (PRs) based on average marginal predictions, accounting for the complex survey design. Fifty-three percent of adults reported taking action to reduce sodium intake. Prevalence of action was highest among adults who received advice (83%), followed by adults taking antihypertensive medications, adults with diabetes, adults with kidney disease, or adults with a history of cardiovascular disease (range, 73%-75%), and lowest among adults aged 18-24 years (29%). Overall, 23% of adults reported receiving advice to reduce sodium intake. Receiving advice was associated with taking action (prevalence ratio=1.59; 95% CI=1.56, 1.61), independent of sociodemographic and health characteristics, although some disparities were observed across race/ethnicity and BMI categories. Our results suggest that more than half of U.S. adults in 26 states and two territories are taking action to reduce sodium intake, and doctor or health professional advice is strongly associated with action.

To determine the prevalence, characteristics and effects on the activities of daily living of menstruation disturbances among adolescent girls. Descriptive, cross-sectional study. A public school in the city of Petrolina, Brazil. 218 female adolescents of ages between 12 and 17 years. We used a structured questionnaire addressing the socio-demographic and menstrual characteristics of the adolescents. The intensity of menstrual pain and its effect on the activities of daily living were measured using an 11-point numeric rating scale. The mean age of adolescent girls was 13.7 ± 1.5 years. The menstrual cycles of 67% were regular, while 33% were irregular. Dysmenorrhea had a prevalence of 73%, and school absenteeism was observed among 31% of the adolescents. In addition, 66% of the participants considered that dysmenorrhea affected their activities of daily living. Associations were found between the intensity of pain and the variables: school absenteeism; affected activities of daily living; need to use medications; and between affected activities of daily living and school absenteeism (P < .05). Among the menstrual disturbances observed dysmenorrhea stood out due to its high prevalence among adolescents with a negative effect on adolescents' activities of daily living. Early diagnosis and knowledge about menstrual disturbances are essential because in addition to reiterating the importance of implementing health education actions, they also help to choose appropriate treatments, thus minimizing the negative effects of these disturbances on the lives of adolescents.

Habitat characteristics determine the presence of individuals through resource availability, but at the same time, such features also influence the occurrence of parasites. We analyzed how birds respond to changes in interior forest structures, to forest management regimes, and to the risk of haemosporidian infections. We captured and took blood samples from blackcaps (Sylvia atricapilla) and chaffinches (Fringilla coelebs) in three different forest types (beech, mixed deciduous, spruce). We measured birds' body asymmetries, detected avian haemosporidians, and counted white blood cells as an immune measure of each individual per forest type. We used, to our knowledge for the first time, continuous forest structural parameters to quantify habitat structure, and found significant effects of habitat structure on parasite prevalence that previously have been undetected. We found three times higher prevalence for blackcaps compared with chaffinches. Parasite intensity varied significantly within host species depending on forest type, being lowest in beech forests for both host species. Structurally complex habitats with a high degree of entropy had a positive effect on the likelihood of acquiring an infection, but the effect on prevalence was negative for forest sections with a south facing aspect. For blackcaps, forest gaps also had a positive effect on prevalence, but canopy height had a negative one. Our results suggest that forest types and variations in forest structure influence the likelihood of acquiring an infection, which subsequently has an influence on host health status and body condition; however, responses to some environmental factors are host-specific.

To determine the prevalence and molecular characteristics of drug-resistant tuberculosis in Hunan province, drug susceptibility testing and spoligotyping methods were performed among 171 M. tuberculosis isolates. In addition, the mutated characteristics of 12 loci, including katG, inhA, rpoB, rpsL, nucleotides 388 to 1084 of the rrs gene [rrs(388-1084)], embB, pncA, tlyA, eis, nucleotides 1158 to 1674 of the rrs gene [rrs(1158-1674)], gyrA, and gyrB, among drug-resistant isolates were also analyzed by DNA sequencing. Our results indicated that the prevalences of isoniazid (INH), rifampin (RIF), streptomycin (SM), ethambutol (EMB), pyrazinamide (PZA), capreomycin (CAP), kanamycin (KAN), amikacin (AKM), and ofloxacin (OFX) resistance in Hunan province were 35.7%, 26.9%, 20.5%, 9.9% 15.2%, 2.3%, 1.8%, 1.2%, and 10.5%, respectively. The previously treated patients presented significantly increased risks for developing drug resistance. The majority of M. tuberculosis isolates belonged to the Beijing family. Almost all the drug resistance results demonstrated no association with genotype. The most frequent mutations of drug-resistant isolates were katG codon 315 (katG315), inhA15, rpoB531, rpoB526, rpoB516, rpsL43, rrs514, embB306, pncA96, rrs1401, gyrA94, and gyrA90. These results contribute to the knowledge of the prevalence of drug resistance in Hunan province and also expand the molecular characteristics of drug resistance in China.

Female genital mutilation/cutting (FGM/C) has no medical benefits and is associated with serious health complications. FGM/C including medicalization is illegal in Kenya. Capacity building for nurse-midwives to manage and prevent FGM/C is therefore critical. Determine the current FGM/C knowledge and effect of training among nurse-midwives using an electronic tool derived from a paper-based quiz on FGM/C among nurse-midwives. Nurse-midwives ( n =26) were assessed pre- and post-FGM/C training using a quiz comprising 12 questions. The quiz assessed the following factors: definition, classification, determining factors, epidemiology, medicalization, prevention, health consequences, and nurse-midwives' roles in FGM/C prevention themes. The scores for individuals and all the questions were computed and compared using SPSS V22. The mean scores for the quiz were 64.8%, improving to 96.2% p < 0.05 after training. Before the training, the following proportions of participants correctly answered questions demonstrating their knowledge of types of cutting (84.6%), link with health problems (96.2%), FGM/C-related complications (96.2%), communities that practice FGM/C (61.5%), medicalization (43.6%), reinfibulation (46.2%), dissociation from religion (46.2%), and the law as it relates to FGM/C (46.2%). The participants demonstrated knowledge of FGM/C-related complications with the proportion of nurse-midwives correctly answering questions relating to physical impact (69.2%), psychological impact (69.2%), sexual impact (57.7%), and social impact (38.5%). Additionally, participant awareness of NM roles in managing FGM/C included the following: knowledge of the nurse-midwife as counselor (69.2%), advocate (80.8%), leader (26.9%), role model (42.3%), and caregiver (34.6%). These scores improved significantly after training. Substantial FGM/C-related knowledge was demonstrated by nurse-midwives. They, however, showed challenges in preventing/rejecting medicalization of FGM/C, and there were knowledge gaps concerning sexual and social complications, as well as the specific roles of NM. This underscores the need to implement innovative FGM/C training interventions to empower health professionals to better respond to its management and prevention.

The unlimited access to sexual features in the World Wide Web has raised concerns about excessive and problematic online-sex use. However, little is known about antecedents of internet-sex use of different intensity. Based on a representative German sample of 2,522 participants between the ages of 14 and 97 years, the aims of the present study were (1) to determine the prevalence rates of online-sex users with the short version (ISSTGSV) of the Internet Sex Screening Test and (2) to associate online-sex use with anxious vs. avoidant partner attachment patterns and "Big Five" personality traits as potential antecedents. The ISST is a brief, one-dimensional and reliable measure of online-sex activities (rtt = .69). Overall, 14.7% of respondents reported occasional and 4.2% intensive online-sex use. In multivariate analysis, online-sex use was significantly positively associated with male sex, younger age, unemployment and an anxious partner attachment pattern and negatively with conscientiousness and agreeableness. Arousal and satisfaction by virtual enactment of sexual phantasies may be attractive for anxiously attached persons who find it difficult to commit to a real life relationship due to fear of rejection or low self-esteem. More knowledge about the individual antecedents of intensive online-sex use may also be helpful for the development of consultation and treatment strategies for excessive and addictive online-sex use.

Results The ISST is a brief, one-dimensional and reliable measure of online-sex activities (rtt = .69). Overall, 14.7% of respondents reported occasional and 4.2% intensive online-sex use. In multivariate analysis, online-sex use was significantly positively associated with male sex, younger age, unemployment and an anxious partner attachment pattern and negatively with conscientiousness and agreeableness. Conclusions Arousal and satisfaction by virtual enactment of sexual phantasies may be attractive for anxiously attached persons who find it difficult to commit to a real life relationship due to fear of rejection or low self-esteem. More knowledge about the individual antecedents of intensive online-sex use may also be helpful for the development of consultation and treatment strategies for excessive and addictive online-sex use.

A cross-sectional study was conducted among youth clients of hotel-based female sex workers (YCHBFSWs) in nine randomly selected hotels in Bangladesh to examine sexual-risk behaviour, condom use and determinants of condom use in last sex, knowledge of HIV, sexually transmitted infection (STI) prevalence and STI care-seeking behaviour. A prestructured questionnaire was used to collect sociodemographic, behavioural, clinical information; urine specimens (before sex) and blood were collected for diagnosis of Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, syphilis and herpes simplex virus 2 (HSV2) infection. One thousand and thirteen participants were enroled in the study. Approximately half of them reported visiting female sex workers (FSWs) at least once a month and 25% visited FSWs at least once a week. Only 12% of participants reported regular condom use. The prevalence of N. gonorrhoeae, C. trachomatis, T. vaginalis, syphilis and HSV2 was 2.2%, 3.9%, 7.2%, 2.6% and 12.9%, respectively. Only 15.3% of the YCHBFSW sought STI care in the past year. Negotiation of condom use with FSWs was the main determinant (odds ratio = 17.95) for condom use at last sex. Male clients of FSWs, including YCHBFSW, are an important bridge population for HIV transmission in Bangladesh and HIV interventions should be designed and implemented for them.

Besides the aging population in China, the following have become serious public health problems: increasing urban population, lifestyle changes and diabetes. We assessed the epidemiology of type 2 diabetes mellitus in China between 2000 and 2014, and analyzed time trends to better determine the prevalence status of diabetes in China and to provide a basis for prevention and decision-making. In our systematic review, we searched China National Knowledge Infrastructure, Chinese VIP Information, Wanfang and PubMed databases for studies on type 2 diabetes mellitus between 2000 and 2014 in China. Two investigators extracted the data and assessed the quality of the included literature independently. We excluded studies that did not use 1999 World Health Organization criteria for diabetes. We also excluded reviews and viewpoints, studies with insufficient data, studies that were not carried out in mainland China and studies on troops, community, schools or physical examination people. We used stata 12.0 to combine the prevalence of all studies, calculated the pooled prevalence and its 95% confidence interval, and analyzed the differences among men/women, urban/rural areas and year of study. We calculated the prevalence of seven geographic areas of China, respectively, and mapped the distribution in the whole country to estimate the pooled prevalence of each area. Our search returned 4,572 studies, 77 of which satisfied the inclusion criteria. The included studies had a total of 1,287,251 participants, in which 680,574 cases of type 2 diabetes mellitus were recorded. The overall prevalence (9.1%) has been increasing since the 1970s, and it increased rapidly with age. The prevalence of the 65-74 years group was as high as 14.1%. Meanwhile, the prevalence among men/women and urban/rural areas was significantly different. The prevalence was 9.9% for men and 11.6% for women, which were significantly higher than the average at the end of the last century and the beginning of this century. The prevalence rate in urban areas (11.4%) was significantly higher than that in rural areas and in urban-rural fringe areas, and the prevalence in rural areas (8.2%) was slightly higher than that in urban-rural fringe areas (7.5%). In addition, the prevalence in each geographic area were estimated and mapped, which showed a large imbalance in the map. Our analysis suggested that type 2 diabetes mellitus is highly prevalent in China. These results underscore the urgent need for the government to vigorously strengthen the management of diabetes prevention and control. © 2016 The Authors.

Objective Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, is an often-severe, understudied disorder. We determined BDD’s prevalence and clinical features on a general adult psychiatric inpatient unit. To our knowledge, only one previous prevalence study has been done in this setting. Method One hundred patients completed 3 self-report measures: the Body Dysmorphic Disorder Questionnaire (BDD-Q), Beck Anxiety Inventory (BAI) and Center for Epidemiologic Studies Depression Scale (CES-D). Those who screened positive for BDD were interviewed to confirm DSM-IV BDD and its clinical features. Charts were reviewed for demographic and clinical information. Results BDD was diagnosed in 16.0% (95% CI=8.7–23.3%) (n=16) of patients. A high proportion of those with BDD reported that BDD symptoms contributed to suicidality. Patients revealed BDD symptoms to a mean of only 15.1%±33.7% lifetime mental health clinicians; only one (6.3%) reported symptoms to his current inpatient psychiatrist. Most did not disclose their symptoms due to embarrassment. Those with BDD were younger (P=.008) and had higher CES-D scores (P=.008). The two groups did not significantly differ on BAI score, demographic characteristics or discharge diagnoses. Conclusions BDD is relatively common but underdiagnosed in psychiatric inpatients and is associated with more severe depressive symptoms. PMID:18164943

The prevalence of and risk factors for shedding Toxocara eggs in cats older than 6 months were determined by examining 670 faecal samples collected in 4 cross-sectional studies in the Netherlands. Additionally, cat owners provided information on their attitude towards routine deworming. Samples were examined using the centrifugal sedimentation flotation method. Overall Toxocara prevalence was 7.2 %. Multivariable logistic regression analysis revealed that young age and living in rural areas were significant risk factors for shedding Toxocara eggs. Moreover, the more time a cat was allowed to roam outdoors, the higher was its risk to shed Toxocara as compared to cats with no outdoor access at all. For 199 cats (81.6 % of cats subjected to a deworming regimen) owners provided the reason for treatment. The main reason for routine deworming (80.4 %) concerned the cat's health and only 10.6 % of the cats were treated for public health reasons. Moreover, the generally advocated four-times-a-year deworming advice was applied on only 24.5 % of cats. We concluded that free roaming is a key factor in the acquisition of patent Toxocara infections leading to the environmental contamination with Toxocara eggs. Additionally, the knowledge of cat owners is still insufficient to expect them to make sound decisions on routine deworming.

To determine HIV prevalence among female sex workers in the Gambia and HIV risk factors, we accrued participants (n = 251) through peer-referral and venue-based recruitment. Blood samples were screened for HIV and participants were administered a questionnaire. Bivariate and multivariate logistic regression identified factors associated with HIV status. Forty respondents (15.9%) were HIV-positive: 20 (8.0%) were infected with HIV-1 only, 10 (4.0%) with HIV-2 only, and 10 (4.0%) with both HIV-1 and HIV-2; 12.5% (n = 5/40) knew their status. Condom usage at last sex was 97.1% (n = 170/175) with new clients and 44.2% (n = 53/120) with non-paying partners. Having a non-paying partner, living with relatives or friends, having felt scared to walk in public, selling sex in multiple locations, and recent depressive symptoms were positively associated with HIV under multivariate regression. Female sex workers have a higher prevalence of HIV compared to the general Gambian population. Interventions should be rights-based, promote safer sex practices and regular testing for female sex workers and linkage to HIV treatment and care with adherence support for those living with HIV. In addition, service providers should consider non-paying partners of female sex workers, improve knowledge and availability of condoms and lubricant, and address safety and mental health needs.

This study determined the prevalence of intestinal parasites, particularly pathogenic Entamoeba sp. (E. histolytica), in patients attending three hospitals in Jeddah City, King Abdulaziz University Hospital, King Abdulaziz Hospital and King Fahad Hospital for gastro-intestinal troubles. 186 stool specimens were examined microscopically for parasites and by ELISA kit (E. histolytica II) for true E. histolytica. 83 samples (44.6%) were positive by microscopy for at least one parasite. Of which, 23 (12.4%) showed two parasites and 15 (8.1%) three parasites. Eight different parasite species were identified. The most prevalent were E. histolytica/dispar (n = 26, 31.3%) and Giardia lamblia (n = 13, 15.7%). Others were Blastocytosis hominis (n = 12, 14.5%), Entamoeba coli (n = 11, 13.3%), Trichuris trichuria (n = 8, 9.6%), Endolymax nana (n = 6, 7.2%), Hymenolepes nana (n = 4, 4.8%) and Chilomastix mesnili (n = 3, 3.6%). Only five stool samples (19%) from those identified by microscopy to contain E. histolytica/dispar, were E. histolytica positive by E. histolytica II ELISA. For the first time to the authors' knowledge the true prevalence of E. histolytica in Saudi Arabia was 2.7%. E. histolytica II ELISA proved to be a highly useful technique to differentiate pathogenic E. histolytica from non pathogenic E. dispar.

To determine the prevalence and associated risk factors of diabetic peripheral neuropathy (DPN) among newly diagnosed diabetes mellitus patients in Mulago Hospital. A cross-sectional study was conducted among 248 newly diagnosed adult diabetic patients. Using the standard Neuropathy Symptom Score (NSS) and Neuropathy Disability Score (NDS) criteria, we screened them for neuropathy. Data on the socio-demographics, age, duration of symptoms and history of diabetic ulcer were analyzed using a multiple logistic regression. A p-value <0.05 was considered significant. The majority of study patients (62.1%) were male. The overall prevalence of DPN was 29.4 %. Nearly sixteen percent had moderate neuropathy and only five percent had severe neuropathy. Age above 60 years was significantly associated with the presence of DPN; (OR 3.72; 95% CI 1.25 - 11.03; p=0.018). The history of ever having a foot ulcer was significantly associated with peripheral neuropathy (OR 2.59; 95% CI: 1.03 - 6.49, p = 0.042). DPN occurs in 1 in 4 of newly diagnosed diabetic patients in Mulago hospital. Two thirds of these patients had moderate to severe neuropathy. DPN was independently associated with increasing age. Early diagnosis of diabetes mellitus, increased diabetes knowledge and regular blood sugar screenings would play an important role in identifying this problem.

Objective To determine the prevalence rate of head louse infestation among elementary students, and examine the associated factors with infection in the city of Aran and Bidgol. Methods A total of 19 boys' and girls' primary schools were selected by multistage, systematic random sampling. Overall, 3 590 students were examined for head lice infestation in urban areas of Aran and Bidgol during 2008. The diagnosis was based on live louse or nit on the scalp of students. The students were screened by standard questionnaire and demographic data in addition to related information were obtained by interview and observation. The data were analyzed by SPSS software using chi-square and Fisher's exact tests. Results The mean age of students was (8.68±1.58) years ranging between 6-12 years. The total prevalence of head louse infestation was 0.47%. This rate was 0.42% and 0.05% in female and male, respectively. There was a significant association between pediculosis and sex, father's job, mother's education, access to bathroom in home, prior infection, drug use and nationality, respectively (P<0.05). Conclusions The results showed that pediculosis was not a major health priority among primary school in city of Aran and Bidgol. However, enhancing the knowledge of students about head lice infestation and the existence of health teachers in schools can play a significant role in disease control.

The purpose of this study was to determine the prevalence of stress urinary incontinence (SUI) in recreationally active women attending gyms or exercise classes. Data were collected on the frequency and severity of incontinence and the prevalence of SUI risk factors; screening for PFM dysfunction in a fitness appraisal; symptom modification strategies; knowledge of pelvic floor muscle (PFM) exercises and the Pelvic Floor First (PFF) initiative. Three hundred and sixty-one women aged 18-83 who attended exercise classes or gyms in Western Australia were surveyed. Nearly half (49.3 %) of participants reported SUI, the majority of whom slight or moderate leakage. Ninety-six per cent reported at least one SUI risk factor, with the mean being 2.7 (SD = 1.4). Almost all women surveyed had heard of PFM exercises (97.2 %), but only 15.2 % of participants were screened for PFM dysfunction in a fitness appraisal. Forty-three per cent reported that a fitness instructor cued PFM activation during a workout. Less than 1 in 10 (9.7 %) of the women surveyed had heard about the PFF initiative. Urinary incontinence is common in women attending gyms or exercise classes, but is rarely screened for. More education is required to encourage fitness leaders to screen exercise participants and to provide PFM-'friendly" modifications.

Smoking, diet, and physical exercise are key determinants of health. This study assessed changes over 10 years and their relationship to changes in health beliefs and risk awareness. A survey was carried out of university students from 13 European countries (Belgium, England, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, The Netherlands, Poland, Portugal, and Spain) in 1990 (4,701 men, 5,729 women) and repeated in 2000 (4,604 men, 5,732 women). We assessed smoking, exercise, fruit and fat intake, beliefs in the importance of behaviors for health, and awareness of the influence of behaviors on heart disease risk. Smoking prevalence increased and fruit consumption decreased between 1990 and 2000, while physical exercise and fat intake were more stable. There were large variations between country samples. Health beliefs weakened, with marked decreases in beliefs about smoking and diet. Across country samples, changes in beliefs correlated with changes in the prevalence of behaviors. Awareness of the effects of smoking and exercise was stable, but knowledge of the role of fat intake increased over the decade. The differences in health behaviors, beliefs, and risk awareness between the two surveys were disappointing in this educated sector of young adult Europeans. The association between changes in beliefs and prevalence of behavior emphasizes the importance of enhancing positive attitudes to healthier lifestyles.

Background Hepatitis B Virus (HBV) may progress to serious consequences and increase dramatically beyond endemic dimensions that transmits to or from health care workers (HCWs) during routine investigation in their work places. Basic aim of this study was to canvass the safety of HCWs and determine the prevalence of HBV and its possible association with occupational and non-occupational risk factors. Hepatitis B vaccination coverage level and main barriers to vaccination were also taken in account. Results A total of 824 health care workers were randomly selected from three major hospitals of Peshawar, Khyber Pakhtunkhwa. Blood samples were analyzed in Department of Zoology, Kohat University of Science and Technology Kohat, and relevant information was obtained by means of preset questionnaire. HCWs in the studied hospitals showed 2.18% prevalence of positive HBV. Nurses and technicians were more prone to occupational exposure and to HBV infection. There was significant difference between vaccinated and non-vaccinated HCWs as well as between the doctors and all other categories. Barriers to complete vaccination, in spite of good knowledge of subjects in this regard were work pressure (39.8%), negligence (38.8%) un-affordability (20.9%), and unavailability (0.5%). Conclusions Special preventive measures (universal precaution and vaccination), which are fundamental way to protect HCW against HBV infection should be adopted. PMID:21645287

The common manifestations of atopic dermatitis (AD) appear sequentially with involvement of the cheeks in infancy, flexural extremities in childhood, and hands in adulthood. Although less common clinical manifestations are well described, they have not been the subject of epidemiologic studies to describe their prevalence in specific age groups. This observational, cross-sectional, comparative study included 131 children younger than 18 of both sexes with AD who attended the clinics of the Dermatology Department of the National Institute of Pediatrics in Mexico City. Patients were examined to determine the presence of infrequent clinical manifestations of AD during infancy, preschool and school age, and adolescence and stratified according to sex, age, and number of clinical signs. A chi-square test was used to detect differences according to age and sex. Logistic regression analysis was also performed. The main findings according to age were genital dermatitis and papular-lichenoid dermatitis variant in infants; atopic feet, prurigo-like, nummular pattern, and erythroderma in preschool and school-aged children; and eyelid eczema and nipple dermatitis in adolescents. The risk of development of nipple dermatitis and eyelid eczema increased with age, and the development of genital dermatitis decreased with age. The knowledge of the prevalence of less common clinical manifestations of AD according to age in different populations might be helpful in diagnosing incipient cases of AD. © 2012 Wiley Periodicals, Inc.

Background Escherichia coli O157 (EcO157) infection has been recognized as an important global public health concern. But information on the prevalence of EcO157 in cattle at the global and at the wider geographical levels is limited, if not absent. This is the first meta-analysis to investigate the point prevalence of EcO157 in cattle at the global level and to explore the factors contributing to variation in prevalence estimates. Methods Seven electronic databases- CAB Abstracts, PubMed, Biosis Citation Index, Medline, Web of Knowledge, Scirus and Scopus were searched for relevant publications from 1980 to 2012. A random effect meta-analysis model was used to produce the pooled estimates. The potential sources of between study heterogeneity were identified using meta-regression. Principal findings A total of 140 studies consisting 220,427 cattle were included in the meta-analysis. The prevalence estimate of EcO157 in cattle at the global level was 5.68% (95% CI, 5.16–6.20). The random effects pooled prevalence estimates in Africa, Northern America, Oceania, Europe, Asia and Latin America-Caribbean were 31.20% (95% CI, 12.35–50.04), 7.35% (95% CI, 6.44–8.26), 6.85% (95% CI, 2.41–11.29), 5.15% (95% CI, 4.21–6.09), 4.69% (95% CI, 3.05–6.33) and 1.65% (95% CI, 0.77–2.53), respectively. Between studies heterogeneity was evidenced in most regions. World region (p<0.001), type of cattle (p<0.001) and to some extent, specimens (p = 0.074) as well as method of pre-enrichment (p = 0.110), were identified as factors for variation in the prevalence estimates of EcO157 in cattle. Conclusion The prevalence of the organism seems to be higher in the African and Northern American regions. The important factors that might have influence in the estimates of EcO157 are type of cattle and kind of screening specimen. Their roles need to be determined and they should be properly handled in any survey to estimate the true prevalence of EcO157. PMID:24691253

Uremic sarcopenia and dynapenia are prevalent in chronic kidney disease patients, including dialysis patients. The present study was designed to determine the prevalence of sarcopenia and dynapenia and their determinants in peritoneal dialysis (PD) patients in Tehran, Iran. All eligible PD patients at the peritoneal dialysis centers of Tehran were included in this cross-sectional study. Skeletal muscle mass and muscle strength were assessed using bioelectrical impedance analysis and hand grip strength, respectively. Physical performance was determined by a 4-m walk gait speed test. The prevalence rates of dynapenia and sarcopenia were 43.0% and 11.5% in the PD patients, respectively. There were significant associations between the prevalence of dynapenia and the age of patients (P = .03), physical activity level (P = .04), and the presence of diabetes mellitus (P = .005). In addition, a significant association was found between the prevalence of sarcopenia and sex (P = .009). This study indicates that uremic sarcopenia and dynapenia are prevalent in PD patients in Tehran, Iran. These conditions may contribute to physical disability, decreased the quality of life, increased morbidity, and a high mortality rate. Therefore, prevention and treatment of uremic sarcopenia and dynapenia are necessary for Iranian PD patients.

Background Multidrug resistant tuberculosis (MDR-TB), is an emerging public health problem in sub-Saharan Africa (SSA). This study aims to determine the trends in prevalence of MDR-TB among new TB cases in sub-Saharan Africa over two decades. Methods We searched electronic data bases and accessed all prevalence studies of MDR-TB within SSA between 2007 and 2017. We determined pooled prevalence estimates using random effects models and determined trends using meta-regression. Results Results: We identified 915 studies satisfying inclusion criteria. Cumulatively, studies reported on MDR-TB culture of 34,652 persons. The pooled prevalence of MDR-TB in new cases was 2.1% (95% CI; 1.7–2.5%). There was a non-significant decline in prevalence by 0.12% per year. Conclusion We found a low prevalence estimate of MDR-TB, and a slight temporal decline over the study period. There is a need for continuous MDR-TB surveillance among patients with TB. PMID:28945771

Verify the knowledge of teachers from public and private schools about stuttering and attest the effectiveness of the Teacher Training Program on Stuttering in the expansion of this knowledge. The study sample comprised 137 early-childhood teachers. Initially, the teachers responded to a questionnaire on stuttering. After that, 75 teachers attended a 4-hour Teacher Training Program on Stuttering. One month later, the teachers responded to the same questionnaire again. The following points were observed after the training program: increased percentage of teachers who consider as low the prevalence of stuttering in the population; beginning of reports stating that stuttering is more frequent in males; increased number of teachers who consider stuttering hereditary; decreased incidence of teachers who believe stuttering is psychological; prevalence of those who believe stuttering is a consequence of multiple causes; decreased rate of teachers who believe stuttering is emotional; a better understanding of how educators should behave to help stutterers. Before the course, the teachers had some knowledge regarding stuttering, but it was insufficient to differentiate from other language disorders. The Program expanded their knowledge on stuttering. However, it proved to be more effective with respect to the characteristics of stuttering than to the attitudes of the teachers.

Breast cancer (BC) is the most common female malignancy in the world and Turkey. Its prevalence and mortality are surprisingly increasing at a rapid rate. The objective of this study was to determine the effectiveness of training sessions on women's knowledge of relevant risk factors of BC and screening methods, screening behaviors and health beliefs among of healthy women in Turkey. In this study, in order to establish the efficiency of BC training, a semi-empirical single group pre-test & post-test research model was used. The data were collected by using a self-administered questionnaire and by using the Turkish version of Champion's health belief model scale (CHBMS). The pre-test was performed before the training and after one week of the training, post-test was performed with a questionnaire having the same content. In total, 244 women participated in the study. The average age of the women was 39.44 (SD=1.06) years. The mean total knowledge score increased significantly (p<.001) from 9.05 in the pre-test to 16.53 in the post-test. The results showed that both mean knowledge scores and CHBMS subscales scores of the women were increased significantly (p<.001) from the pre-test to the post-test. In multiple linear regression analysis, BC screening knowledge of women with susceptibility, benefit, self-efficacy and health motivation subscales of CHBMS, breast self-examination (BSE) practice and self-efficacy were also significant in the post-test; in the pre- and post-tests, a significant relationship among the level of education of women, susceptibility and seriousness was found (p<.001). The study showed that the training program had profound effects on BC knowledge, screening behaviors and health beliefs of women.

To present the results of a pilot study of an innovative methodology for translating best evidence about spinal cord injury (SCI) for family practice. Review of Canadian and international peer-reviewed literature to develop SCI Actionable Nuggets, and a mixed qualitative-quantitative evaluation to determine Nuggets' effect on physician knowledge of and attitudes toward patients with SCI, as well as practice accessibility. Ontario, Newfoundland, and Australia. Forty-nine primary care physicians. Twenty Actionable Nuggets (pertaining to key health issues associated with long-term SCI) were developed. Nugget postcards were mailed weekly for 20 weeks to participating physicians. Prior knowledge of SCI was self-rated by participants; they also completed an online posttest to assess the information they gained from the Nugget postcards. Participants' opinions about practice accessibility and accommodations for patients with SCI, as well as the acceptability and usefulness of Nuggets, were assessed in interviews. With Actionable Nuggets, participants' knowledge of the health needs of patients with SCI improved, as knowledge increased from a self-rating of fair (58%) to very good (75%) based on posttest quiz results. The mean overall score for accessibility and accommodations in physicians' practices was 72%. Participants' awareness of the need for screening and disease prevention among this population also increased. The usefulness and acceptability of SCI Nugget postcards were rated as excellent. Actionable Nuggets are a knowledge translation tool designed to provide family physicians with concise, practical information about the most prevalent and pressing primary care needs of patients with SCI. This evidence-based resource has been shown to be an excellent fit with information consumption processes in primary care. They were updated and adapted for distribution by the Canadian Medical Association to approximately 50,000 primary care physicians in Canada, in both English and French.

Aim To determine the prevalence of mental and social disorders in adults who attend primary care health centers in Bosnia and Herzegovina. Methods Sixty-nine family physicians from the Primary Care Research Network in Bosnia and Herzegovina each invited 20 randomly selected patients from their practices to complete the Patient Health Questionnaire (PHQ), which consists of 26-58 questions about symptoms and signs of depression, anxiety, somatization disorder, eating disorders, and alcoholism. A total of 1574 patients were invited to participate in the study. Physicians reviewed the PHQ and calculated the final score, which determined a provisional diagnosis. Definitive diagnosis was determined by further questioning and clinical knowledge of the patient. Data collection was performed between November 2003 and January 2004. Lists of non-participants were maintained by the physicians. Results The response rate was 82%. Of 1285 respondents, 61% were women. At least one type of mental or social disorder was found in 26% of the respondents, and 12% had more than one disorder. Somatization disorder, major depression syndrome, and panic syndrome were experienced by 16%, 10%, and 14% of respondents, respectively, while 5% or less were suffering from eating disorders or alcohol abuse. More women than men had somatization disorder, panic syndrome, and binge eating disorder, while more men than women reported alcohol abuse. Conclusion More than one-quarter of all adults who attended family medicine centers in Bosnia and Herzegovina presented with at least one type of mental or social disturbance. New health policies, strengthened professional training, and accessible support networks need to be developed throughout the country. PMID:16758527

The speedy rate of change in the environmental and socio-economics factors may increase the incidence, prevalence and risk of schistosomiasis infections in Zambia. However, available information does not provide a comprehensive understanding of the biogeography and distribution of the disease, ecology and population dynamics of intermediate host snails. The current study used an information-theoretical approach to understand the biogeography and prevalence schistosomiasis and identified knowledge gaps that would be useful to improve policy towards surveillance and eradication of intermediate hosts snails in Zambia. To summarise the existing knowledge and build on past and present experiences of schistosomiasis epidemiology for effective disease control in Zambia, a systematic search of literature for the period 2000-2017 was done on PubMed, Google Scholar and EBSCOhost. Using the key words: 'Schistosomiasis', 'Biomphalaria', 'Bulinus', 'Schistosoma mansoni', 'Schistosoma haematobium', and 'Zambia', in combination with Booleans terms 'AND' and 'OR', published reports/papers were obtained and reviewed independently for inclusion. Thirteen papers published in English that fulfilled the inclusion criteria were selected for the final review. The papers suggest that the risk of infection has increased over the years and this has been attributed to environmental, socio-economic and demographic factors. Furthermore, schistosomiasis is endemic in many parts of the country with infection due to Schistosoma haematobium being more prevalent than that due to S. mansoni. This review also found that S. haematobium was linked to genital lesions, thus increasing risks of contracting other diseases such as HIV and cervical cancer. For both S. haematobium and S. mansoni, environmental, socio-economic, and demographic factors were influential in the transmission and prevalence of the disease and highlight the need for detailed knowledge on ecological modelling and mapping the distribution of the disease and intermediate host snails for effective implementation of control strategies.

Acinetobacter seifertii is a recently described species that belongs to the Acinetobacter calcoaceticus-Acinetobacter baumannii complex. It has been recovered from clinical samples and is sometimes associated with antimicrobial resistance determinants. We present here the case of three A. seifertii clinical isolates which were initially identified as Acinetobacter sp. by phenotypic methods but no identification at the species level was achieved using semi-automated identification methods. The isolates were further analysed by whole genome sequencing and identified as A. seifertii. Due to the fact that A. seifertii has been isolated from serious infections such as respiratory tract and bloodstream infections, we emphasize the importance of correctly identifying isolates of the genus Acinetobacter at the species level to gain a deeper knowledge of their prevalence and clinical impact.

Asthma affects more than two million Australians, and of growing concern for the Australian health system is asthma in the over 65+ age group. Between 1997 and 2001, 61% of all deaths attributable to asthma occurred in people aged over 65 and mortality in this group remains higher than the rate for all other groups. An investigation of older Australians' perceptions of asthma prevalence and impact was conducted in the Illawarra region of New South Wales. Eight focus groups with the target audience were conducted to explore their attitudes, knowledge and skills with regard to asthma symptoms, prevalence, diagnosis and treatment. Additionally, 12 in-depth interviews were conducted with a broad range of health professionals to ascertain their opinion of the target audience's asthma knowledge and understanding. Results indicate that these older Australians are unaware of the prevalence and severity of asthma in their age group, have limited understanding of symptoms and treatments, and associate the condition with children. Health professionals reported that older people minimise respiratory symptoms as a natural part of ageing. Qualitative analysis using the Health Belief Model, suggests that heightened knowledge and awareness is necessary to bring about voluntary behaviour change in order to reduce asthma mortality and morbidity in the 65+ age group.

To find and describe perceptions, beliefs, knowledge and attitudes adopted by healthy people regarding liver disease, who attend at three medical institutions. To estimate how the academic and socioeconomic level operate as determinant factors. Descriptive transversal study that includes a 31 question-questionnaire made in a group of 390 healthy people who were in the waiting rooms at Hospital Cayetano Heredia (HNCH), Policlinico Peruano Japones (PPJ) and Clinica Angloamericana (CAA), reflecting low, medium and medium-high socio economic status respectively. Data was processed with SPSS software. We found that 218/390 (56%) people had higher education level, and 64% were women. "Eating high-fat meals" had the highest percentage (91%) among perceptions of liver disease. "Bad breath" and "heartburn" were referred as symptoms of liver disease, among people with a higher education level. Less than 50% of people knew about routes of transmission of hepatitis B, associated with its prevention and treatment. Beliefs and wrong perceptions about liver disease are prevalent among people; dyspepsia was inaccurately associated. There is an inappropriate knowledge about routes of transmission, preventive measures and treatment, which was reflected in people with lower education level as well as in those with higher education and socioeconomic level.

Notwithstanding the efforts of health educators and other health professionals regarding tobacco and smoking cessation, research indicates that hookah smoking among college students remains a health concern. Research shows an upward trend in college students' hookah use. The purpose of this study was to identify and describe potential patterns/differences in college students' hookah use, and the relations among attitudes toward and knowledge about hookah use and use of this drug. A four-page, 20-item survey was used to collect data from participants (N = 403) and to measure participants 'recent use, knowledge of health risks, attitudes and reasons for hookah use among college students. Results indicated increased prevalence rates (53.8%) among participants of this study. Participants' recent hookah use was consistent with that of current research. Study findings supports current research, which found that college students have low negative perceptions of the health risks (addictive and detrimental properties) of hookah use. Analyses also determined that college students' attitudes toward hookah was associated with use of this drug. Regarding reasons why students may use hookah, data analysis indicated statistical significance in lifetime hookah use based on reasons for use. Study provide information for health educators creating hookah risk awareness educational programs aimed at reducing rates of hookah smoking among college students.

Disaster Mental Health Epidemiology: Methodological Review and Interpretation of Research Findings.

North, Carol S

2016-01-01

Worldwide, disasters are increasing in frequency and severity. Mental health consequences of disasters are extensive, and knowledge of anticipated mental health effects is needed for effective disaster response. Difficulties inherent in conducting disaster research have limited the understanding of research findings. This article presents and interprets disaster mental health research findings in the context of research methods. A brief history of the disaster mental health research field is provided, and the presentation of findings is ordered into topical areas of disaster mental health consequences and timing and prediction of mental health outcomes. Results of different studies varied greatly by several main characteristics of research methods, especially methods of psychiatric assessment, sampling and exposure group determination, and consideration of confounding variables. In conclusion, many complexities in conducting disaster mental health research have limited the understanding and interpretation of available knowledge needed to inform efforts to plan and carry out effective mental health responses to disasters. Thoughtful interpretation of findings in the context of research design and methods is vital to accurate understanding of the types, prevalence, and predictors of anticipated mental health effects of disasters. A wealth of knowledge from disaster mental health research has accumulated in recent decades, but more research is still needed to resolve inconsistent findings through methodological refinements.

This is a cross-sectional, descriptive study among Malay women admitted in the antenatal and postnatal ward to determine the prevalence and use of herbal medicines during pregnancy and elemental analysis in the most popular herbs. A total of 460 women were surveyed. Herbal medicine use during pregnancy was 34.3%, while 73% utilized herbal medicines during labor, because of a belief that it may shorten and ease labor. The most commonly used herbal medicines in pregnancy were Anastatica hierochuntica L. (60.1%) followed by coconut oil (35.4%). The majority of women (89.2%) used only one type of herbal medicines and took one capsule/glass (38%) per day. Herbal medicines use by pregnant women is largely unsupervised (81%), with most women getting information from their parents (60.7%) and buying the products directly from traditional midwives (32.2%) and 77% agreed upon its efficacy and safety. From the 460 respondents, 89.8% women were in the low end of the herbs knowledge. There was a significant difference found between knowledge score and income (P < 0.05). Microdiffraction analysis revealed significant presence of carbon, oxygen, silica, calcium, magnesium, aluminium, potassium, zinc, and iron that were found in Anastatica hierochuntica L. and proved to have good benefits for pregnancy.

The objective of this study was to determine the prevalence of waterpipe (shisha) smoking and associated factors among Malaysian university students. A total of 200 university students from Management and Science University participated in this study. The survey was conducted by simple random sampling by randomly distributing self-administered questionnaires to the library, cafeterias and classes. The protocol of this study was approved by the ethics committee of Management and Science University. Consent forms were obtained from the students before they answered the questionnaire. Statistical analyses were performed using the Statistical Package for Social Science (SPSS) version 13. with the Student's t-test for comparison of the mean practice and backward multiple linear regression for multivariate analysis. The majority of the subjects were male, single, Malay and from urban areas (61.5%, 94.5%, 66%, 76.5%; respectively). In this study 30% of the study participants were shisha smokers. Regarding knowledge about shisha smoking, the majority (48.5%) mentioned that shisha is less harmful than cigarettes and 55% reported that shisha is less addictive. Univariate analysis showed that age, race, sex and income significantly influenced the practice of smoking shisha among university students (p=0.019, p=0.002, p=0.001, p=0.018; respectively). For multivariate analysis, income and gender demonstrated significant influence (both p=0.001). There was a high prevalence of shisha smoking among Malaysian university students and knowledge about the dangers is low. Income and gender significantly influenced the practice of smoking shisha in our population. Banning of smoking including shisha smoking in public places is strongly recommended.

Generationing, Stealthing, and Gift Giving: The Intentional Transmission of HIV by HIV-Positive Men to their HIV-Negative Sex Partners.

Klein, Hugh

2014-11-06

Gift giving is the process by which an HIV-positive person purposely infects an HIV-negative person with HIV, usually with that person's knowledge and consent. Little has been written about this HIV transmission practice. In this paper, two specific types of gift giving - generationing and stealthing - are explained and introduced to the scientific literature. Generationing is a type of gift giving in which one gift giver successfully infects a previously-uninfected man with HIV, and then the two men collaborate in an effort to seroconvert another man, and so forth. Stealthing is another type of gift giving in which an HIV-positive man actively tries to infect an HIV-negative man with HIV, without the latter's knowledge or consent. The present study reports on the prevalence of gift giving (4.6%) in a population of men who use the Internet specifically to identify partners for unprotected sex. The research is based on a national random sample of 332 men who have sex with men, identified from 16 websites. Data were collected via telephone interviews conducted between January 2008 and May 2009. The paper concludes with a discussion of the implications of these findings for HIV prevention and intervention efforts. Most notably, to the extent that generationing, stealthing, and gift giving occur among MSM, they represent a very high risk of HIV transmission. More work needs to be done to understand these behaviors, the factors that underlie them, and to determine how prevalent they are in the bare-backing population of MSM.

Computer vision syndrome (CVS) is a condition in which a person experiences one or more of eye symptoms as a result of prolonged working on a computer. To determine the prevalence of CVS symptoms, knowledge and practices of computer use in students studying in different universities in Malaysia, and to evaluate the association of various factors in computer use with the occurrence of symptoms. In a cross sectional, questionnaire survey study, data was collected in college students regarding the demography, use of spectacles, duration of daily continuous use of computer, symptoms of CVS, preventive measures taken to reduce the symptoms, use of radiation filter on the computer screen, and lighting in the room. A total of 795 students, aged between 18 and 25 years, from five universities in Malaysia were surveyed. The prevalence of symptoms of CVS (one or more) was found to be 89.9%; the most disturbing symptom was headache (19.7%) followed by eye strain (16.4%). Students who used computer for more than 2 hours per day experienced significantly more symptoms of CVS (p=0.0001). Looking at far objects in-between the work was significantly (p=0.0008) associated with less frequency of CVS symptoms. The use of radiation filter on the screen (p=0.6777) did not help in reducing the CVS symptoms. Ninety percent of university students in Malaysia experienced symptoms related to CVS, which was seen more often in those who used computer for more than 2 hours continuously per day. © NEPjOPH.

Studies completed outside of Canada have reported a high rate of mental illness and psychotropic medication use among bariatric surgery candidates with variable impacts on surgical and mental health outcomes. To our knowledge, there has been no published Canadian data on this issue. We conducted a secondary analysis of de-identified data from the Ontario Bariatric Registry for all individuals who completed both a baseline and psychological assessment between April 1, 2010, and February 9, 2015 (N = 10,698). We determined the rates of reported mental illness and psychotropic medication use overall and by fiscal year of assessment. A past or present mental illness, most commonly depression, was recorded for 51 % of individuals. At baseline, 38 % were taking at least one psychotropic medication, most commonly antidepressants. Only a small proportion of the population were taking psychotropic medications known to be associated with high potential for weight gain. Although the prevalence of mental illness increased steadily from 35 % in 2010/2011 to 63 % in 2014/2015, there was no corresponding increase in reported medication use. Of those taking psychotropic medications, 13 % did not have a recorded history of mental illness. Consistent with other international studies, our results indicate a high prevalence of mental illness and psychotropic medication use among people referred for bariatric surgery in Ontario, Canada. This supports that accurate screening practices, knowledge about how to manage psychotropic medication pre- and post-operatively and recognition for opportunities to change medications that may be associated with weight gain are required.

Pasteurized donor human milk ("donor milk") is an alternative to formula for supplementation of breastfed infants. We conducted a survey to determine (1) prevalence, trends, and hospital-level correlates of donor milk use for healthy newborns in the northeast United States and (2) clinician knowledge and opinions regarding this practice. We conducted parallel surveys of clinicians (88% nurse and/or lactation consultant) at (1) all birth hospitals in Massachusetts (MA) and (2) all birth hospitals served by a northeast United States milk bank. We asked about hospital use of donor milk for newborns ≥35 weeks' gestation and receiving Level I care in well nursery, hospital-related factors we hypothesized would be associated with this practice, and clinician knowledge and opinions about donor milk use. 35/46 (76%) of MA birth hospitals and 51/69 (74%) of hospitals served by the milk bank responded; 71 unique hospitals were included. Twenty-nine percent of MA birth hospitals and 43% of hospitals served by the milk bank reported using donor milk for healthy newborns. Hospitals that used donor milk for healthy newborns had higher exclusive breastfeeding at hospital discharge than hospitals that did not (77% versus 56%, p = 0.02). Eighty-three percent of respondents agreed or strongly agreed that using donor milk is an effective way to increase the hospital's exclusive breastfeeding rate. Many northeast United States birth hospitals currently use donor milk for healthy newborns. This practice is associated with higher exclusive breastfeeding at hospital discharge. Relationships with breastfeeding after discharge and related outcomes are unknown.

Symposium on understanding and influencing consumer food behaviours for health: executive summary report.

Food consumption patterns in Asia are rapidly changing. Urbanization and changing lifestyles have diminished the consumption of traditional meals based on cereals, vegetables and root crops. These changes are accompa-nied by an increasing prevalence of chronic diseases among Asian populations. ILSI Southeast Asia and CSIRO, Australia jointly organized the Symposium on Understanding and Influencing Food Behaviours for Health, focusing on the use of consumer science to improve food behaviour. The goals of the Symposium were to present an understanding of Asian consumers and their food choices, examine the use of consumer research to modify food choices towards better health, illustrate how health programs and food regulations can be utilized effectively to promote healthier choices, and identify knowledge gaps regarding the promotion of healthy food behaviour in Asian populations. There is no difference in taste perception among Asians, and Asian preference for certain tastes is determined by exposure and familiarity largely dictated by culture and its underlying values and beliefs. Cross-cultural validity of consumer science theories and tools derived from western populations need to be tested in Asia. Information on consumption levels and substitution behaviours for foods and food products, obtained using consumer research methods, can guide the development of food regulations and programs that will enable individuals to make healthier choices. Existing knowledge gaps include consumer research techniques appropriate for use in Asian settings, diet-health relationships from consumption of traditional Asian diets, and methods to address the increasing prevalence of over- and undernutrition within the same households in Asia.

Muscle dysmorphia: current insights.

2016-01-01

Since 1997, there has been increasing research focusing on muscle dysmorphia, a condition underpinned by people's beliefs that they have insufficient muscularity, in both the Western and non-Western medical and scientific communities. Much of this empirical interest has surveyed nonclinical samples, and there is limited understanding of people with the condition beyond knowledge about their characteristics. Much of the existing knowledge about people with the condition is unsurprising and inherent in the definition of the disorder, such as dissatisfaction with muscularity and adherence to muscle-building activities. Only recently have investigators started to explore questions beyond these limited tautological findings that may give rise to substantial knowledge advances, such as the examination of masculine and feminine norms. There is limited understanding of additional topics such as etiology, prevalence, nosology, prognosis, and treatment. Further, the evidence is largely based on a small number of unstandardized case reports and descriptive studies (involving small samples), which are largely confined to Western (North American, British, and Australian) males. Although much research has been undertaken since the term "muscle dysmorphia" entered the psychiatric lexicon in 1997, there remains tremendous scope for knowledge advancement. A primary task in the short term is for investigators to examine the extent to which the condition exists among well-defined populations to help determine the justification for research funding relative to other public health issues. A greater variety of research questions and designs may contribute to a broader and more robust knowledge base than currently exists. Future work will help clinicians assist a group of people whose quality of life and health are placed at risk by their muscular preoccupation.

The prevalence of smoking is higher in Latvia than in most EU countries. This study aimed to determine the level of knowledge of dental students in Latvia about the effects of smoking on oral health and their attitudes toward smoking and its cessation. A cross-sectional survey among all the dental students in Latvia was conducted in 2011. Students at the Riga Stradins University were asked to participate in this anonymous, voluntary survey. The questionnaire included items concerned with the students' own smoking habits, their knowledge of smoking as an addiction and its health effects and their attitudes towards its prevention and cessation in a dental setting. The response rate was 87% (173/200). The Chi-square test and logistic regression were used for the statistical analyses. About one quarter of the students (24%) were daily or occasional smokers and almost half of the male students (46%) had smoked at least 100-times in their lifetime. The students revealed a lack of knowledge about the addictive nature of smoking, in that about half of the students did not consider smoking physically or socially addictive. About one fifth (21.4%) didn't consider environmental tobacco smoke (ETS) harmful to one's health. Although the students' awareness of smoking improved during their studies, the most significant factor related to their knowledge was their own smoking history (OR=2.7; p=0.021). Smoking was frequent among undergraduate dental students and they lacked knowledge of its addictiveness. More emphasis ought to be placed on education with regard to smoking and on cessation services.

In Nigeria, inequity and poor accessibility to quality health care has been a persistent problem. This study aimed to determine knowledge and attitude of civil servants in Osun state towards the National Health Insurance Scheme (NHIS). This is a descriptive, cross sectional study of 380 civil servants in the employment of Osun state government, using multi stage sampling method. The research instruments was pre-coded, semi structured, self administered questionnaires. About 60% were aware of out of pocket as the most prevalent form of health care financing, while 40% were aware of NHIS, television and billboards were their main sources of awareness, However, none had good knowledge of the components of NHIS, 26.7% knew about its objectives, and 30% knew about who ideally should benefit from the scheme. Personal spending still accounts for a high as 74.7% of health care spending among respondents but respondents believed that this does not cover all their health needs. Only 0.3% have so far benefited from NHIS while 199 (52.5%) of respondents agreed to participate in the scheme. A significant association exists between willingness to participate in the NHIS scheme and awareness of methods of options of health care financing and awareness of NHIS (P < 0.05) Poor knowledge of the objectives and mechanism of operation of the NHIS scheme characterised the civil servants under study. The poor knowledge of the components and fair attitude towards joining the scheme observed in this study could be improved upon, if stakeholders in the scheme could carry out adequate awareness seminars targeted at the civil servants.

Defining food literacy: A scoping review.

Truman, Emily; Lane, Daniel; Elliott, Charlene

2017-09-01

The term "food literacy" describes the idea of proficiency in food related skills and knowledge. This prevalent term is broadly applied, although its core elements vary from initiative to initiative. In light of its ubiquitous use-but varying definitions-this article establishes the scope of food literacy research by identifying all articles that define 'food literacy', analysing its key conceptualizations, and reporting outcomes/measures of this concept. A scoping review was conducted to identify all articles (academic and grey literature) using the term "food literacy". Databases included Medline, Pubmed, Embase, CAB Abstracts, CINAHL, Scopus, JSTOR, and Web of Science, and Google Scholar. Of 1049 abstracts, 67 studies were included. From these, data was extracted on country of origin, study type (methodological approach), primary target population, and the primary outcomes relating to food literacy. The majority of definitions of food literacy emphasize the acquisition of critical knowledge (information and understanding) (55%) over functional knowledge (skills, abilities and choices) (8%), although some incorporate both (37%). Thematic analysis of 38 novel definitions of food literacy reveals the prevalence of six themes: skills and behaviours, food/health choices, culture, knowledge, emotions, and food systems. Study outcomes largely focus on knowledge generating measures, with very few focusing on health related outcome measures. Current definitions of food literacy incorporate components of six key themes or domains and attributes of both critical and functional knowledge. Despite this broad definition of the term, most studies aiming to improve food literacy focus on knowledge related outcomes. Few articles address health outcomes, leaving an important gap (and opportunity) for future research in this field. Copyright © 2017 Elsevier Ltd. All rights reserved.

As primary caregiver to under-five children in Ethiopia, mothers' knowledge, perception, and management skills are important to minimize the effects of morbidity and mortality associated with diarrhoeal diseases. A community-based comparative cross-sectional study was conducted in Abramo and Megele 37 kebeles (the last administration division) in Assosa district of western Ethiopia in July 2010. Quantitative data were obtained by a structured questionnaire from 232 randomly-selected mothers having children aged less than five years regarding their knowledge, perception, and management. Qualitative data were also collected by arranging four focus group discussions involving mothers from the two communities. The prevalence of diarrhoeal diseases among under-five children was 33.2%, and the knowledge of mothers about the causes, transmission, and prevention of diarrhoea in the study area was 37.5%. The prevalence of diarrhoeal disease was higher in the settlement area whereas mothers' knowledge was better in the indigenous community; 62.9% of mothers were categorized as having good attitude on causes, transmission, and prevention of diarrhoeal disease. Community water source, water storage container, and knowledge of mothers remained a strong predictor of diarrhoeal morbidity after conducting logistic regression analysis (OR=8.4, CI 3.59-31.85; OR=2.2, CI 1.02-4.89; and OR=3.62, CI 1.23-4.71 respectively). Diarrhoeal morbidity was high in the study areas. On the contrary, knowledge and attitude of mothers, recognizing the danger sign of dehydration due to diarrhoea, and the prevention and management of childhood diarrhoeal diseases were not adequate. Information, education and communication strategy may help increase the knowledge and create positive attitude among mothers regarding the cause, prevention, and management of diarrhoea.

Prevalence of pregnancy experiences and contraceptive knowledge among single adults in a low socio-economic suburban community in Kuala Lumpur, Malaysia

2014-01-01

Background This study aimed to investigate the prevalence of pregnancy experience and its association with contraceptive knowledge among single adults in a low socio-economic suburban community in Kuala Lumpur, Malaysia. Methods A cross-sectional survey was conducted in 2012 among the Kerinchi suburban community. Of the total 3,716 individuals surveyed, young single adults between 18 and 35 years old were questioned with regard to their experience with unplanned pregnancy before marriage. Contraceptive knowledge was assessed by a series of questions on identification of method types and the affectivity of condoms for the prevention of sexually transmitted diseases. Results A total of 226 female and 257 male participants completed the survey. In total, eight female (3.5%) participants reported experience with an unplanned pregnancy before marriage, and five male (1.9 %) participants had the experience of impregnating their partners. The participants had a mean total score of 3.15 (SD = 1.55) for contraceptive knowledge out of a possible maximum score of five. Female participants who had experienced an unplanned pregnancy had a significantly lower contraceptive knowledge score (2.10 ± 1.48) than who had never experienced pregnancy (3.30 ± 1.35), p<0.05. Likewise, male participants who had experienced impregnating their partners had a significantly lower contraceptive knowledge score (1.60 ± 1.50) than those who did not have such experience (3.02 ± 1.59), p<0.05. Conclusion The results showed evidence of premarital unplanned pregnancy among this suburban community. The low level of contraceptive knowledge found in this study indicates the need for educational strategies designed to improve contraceptive knowledge. PMID:25438066

Noninfectious uveitis (NIU) is a collection of intraocular inflammatory disorders that may be associated with significant visual impairment. To our knowledge, few studies have investigated NIU prevalence overall or stratified by inflammation location, severity, presence of systemic conditions, age, or sex. To estimate NIU prevalence using a large, retrospective, administrative claims database. This analysis used the OptumHealth Reporting and Insights database to estimate 2012 NIU prevalence. Analysis was conducted in September 2016. The large administrative insurance claims database includes 14 million privately insured individuals in 69 self-insured companies spanning diverse industries. Included in the study were patients with NIU with 2 or more uveitis diagnoses on separate days in 2012 and continuous enrollment in a health plan for all of 2012 and categorized by inflammation site. We estimated overall NIU prevalence by inflammation site, severity, sex, and age. Patients with anterior NIU were categorized by the presence of systemic conditions. Of the approximately 4 million eligible adult patients, approximately 2.1 million were women, and of the 932 260 children, 475 481 were boys. The adult prevalence of NIU was 121 cases per 100 000 persons (95% CI, 117.5-124.3). The pediatric NIU prevalence was 29 cases per 100 000 (95% CI, 26.1-33.2). Anterior NIU accounted for 81% (3904 cases) of adult NIU cases (98 per 100 000; 95% CI, 94.7-100.9) and 75% (207 cases) of pediatric NIU cases (22 per 100 000; 95% CI, 19.3-25.4). The prevalences of noninfectious intermediate, posterior, and panuveitis were, for adults, 1 (95% CI, 0.8-1.5), 10 (95% CI, 9.4-11.5), and 12 (95% CI, 10.6-12.7) per 100 000, respectively, and for pediatric patients, 0 (95% CI, 0.1-1.1), 3 (95% CI, 1.8-4.1), and 4 (95% CI, 2.9-5.6) per 100 000, respectively. The prevalence of NIU increased with age and was higher among adult females than males. Application of these estimates to the US population suggests that NIU affected approximately 298 801 American adults (95% CI, 290 512-307 324) and 21 879 children (95% CI, 19 360-24 626) in 2015. The estimated prevalence of NIU was 121 cases per 100 000 for adults (95% CI, 117.5-124.3) and 29 per 100 000 for children (95% CI, 26.1-33.2). Prevalence was estimated using administrative claims from a commercially insured population, which may have a different prevalence than other segments of the US population. A better understanding of the prevalence of NIU will help to determine the number of patients affected.

This study examined the association between metabolic syndrome, lifestyle behaviors, and perception and knowledge of current health and cardiovascular disease (CVD) among Asian Indians in the US. The sample comprised of 143 adult Asian Indians recruited through health fairs for survey and bioclinical measures. The prevalence of metabolic syndrome was 32%, much higher than other ethnic groups, did not vary by gender but increased with age. Respondents had high physical inactivity and poor knowledge of CVD risk factors. Dietary behavior, age, number of years lived in the US, self-rated physical and mental health and BMI were significant predictors and explained 40.1% of variance in metabolic syndrome score. Poorer physical health status had the greatest predictive influence on metabolic syndrome. Asian Indians are a high risk group for CVD.

To assess smoking behavior, knowledge of smoking harm, and attitudes toward campus smoking policy at an Egyptian university, an online survey of students, staff, and faculty was conducted (N = 992). The smoking prevalence of 38% among men was in line with Egypt's national average, but the smoking prevalence among women of 20% was much higher than the national average. Smoking status influenced beliefs about smoking harm and attitudes toward smoking policy, with nonsmokers having stronger beliefs about the harm of smoking and showing stronger support for smoking regulations than smokers. Smokers were more knowledgeable about smoking policy than were nonsmokers and differed slightly in their preferences for smoking policy enforcement strategies. These findings contribute to our understanding of how to tailor college smoking policy and programs to an Egyptian context.

Knowledge, perceptions and myths regarding infertility among selected adult population in Pakistan: a cross-sectional study

PubMed Central

2011-01-01

Background The reported prevalence of infertility in Pakistan is approximately 22% with 4% primary and 18% secondary infertility. Infertility is not only a medical but also a social problem in our society as cultural customs and perceived religious dictums may equate infertility with failure on a personal, interpersonal, or social level. It is imperative that people have adequate knowledge about infertility so couples can seek timely medical care and misconceptions can be rectified. We aim to assess the knowledge, perception and myths regarding infertility and suggest ways to improve it. Methods A cross-sectional survey was carried out by interviewing a sample of 447 adults who were accompanying the patients at two tertiary care hospitals in Karachi, Pakistan. They were interviewed one-on-one with the help of a pretested questionnaire drafted by the team after a thorough literature review and in consultation with infertility specialists. Results The correct knowledge of infertility was found to be limited amongst the participants. Only 25% correctly identified when infertility is pathological and only 46% knew about the fertile period in women's cycle. People are misinformed that use of IUCD (53%) and OCPs (61%) may cause infertility. Beliefs in evil forces and supernatural powers as a cause of infertility are still prevalent especially amongst people with lower level of education. Seeking alternative treatment for infertility remains a popular option for 28% of the participant as a primary preference and 75% as a secondary preference. IVF remains an unfamiliar (78%) and an unacceptable option (55%). Conclusions Knowledge about infertility is limited in the population and a lot of misconceptions and myths are prevalent in the society. Alternative medicine is a popular option for seeking infertility treatment. The cultural and religious perspective about assisted reproductive technologies is unclear, which has resulted in its reduced acceptability. PMID:21970548

Many athletes continue to participate in practices and games while experiencing concussion-related symptoms, potentially predisposing them to subsequent and more complicated brain injuries. Limited evidence exists about factors that may influence concussion-reporting behaviors. To examine the influence of knowledge and attitude on concussion-reporting behaviors in a sample of high school athletes. Cross-sectional study. Participants completed a validated survey instrument via mail. A total of 167 high school athletes (97 males, 55 females, 5 sex not indicated; age = 15.7 ± 1.4 years) participating in football, soccer, lacrosse, or cheerleading. Athlete knowledge and attitude scores served as separate predictor variables. We examined the proportion of athletes who reported continuing to participate in games and practices while symptomatic from possible concussion and the self-reported proportion of recalled concussion and bell-ringer events disclosed after possible concussive injury. Only 40% of concussion events and 13% of bell-ringer recalled events in the sample were disclosed after possible concussive injury. Increased athlete knowledge of concussion topics (increase of 1 standard deviation = 2.8 points) was associated with increased reporting prevalence of concussion and bell-ringer events occurring in practice (prevalence ratio [PR] = 2.27, 95% confidence interval [CI] = 1.60, 3.21) and the reporting prevalence of bell-ringer-only events overall (PR = 1.87, 95% CI = 1.38, 2.54). Athlete attitude scores (increase of 1 standard deviation = 11.5 points) were associated with decreases in the proportion of athletes stating they participated in games (PR = 0.74, 95% CI = 0.66, 0.82) and practices (PR = 0.67, 95% CI = 0.59, 0.77) while symptomatic from concussions. Most recalled concussion events in our study were not reported to a supervising adult. Clinicians should be aware that knowledge and attitude influence concussion reporting. Clinicians and administrators should make concussion education a priority and encourage an optimal reporting environment to better manage and prevent concussive injuries in young athletes.

Anaemia in pregnancy is still a concern during the reproductive period, as it is associated with increased maternal and perinatal mortality and morbidity. This study examined the maternal risk factors associated with increased prevalence of anaemia among antenatal and postnatal women. A prospective-retrospective cohort approach was carried out among 1,077 antenatal and 1,000 postnatal women. The haemoglobin was estimated using the cyanmethaemoglobin method. The maternal factors included were age, parity, education, socioeconomic status, spacing, history of bleeding, worm infestation, period of gestation, knowledge regarding anaemia in pregnancy, food selection ability and compliance to iron supplementation. Of the 1,077 antenatal women studied, 540 were anaemic. Among the 1,000 postnatal women, the prevalence was 537 (53.7%). The high prevalence was strongly associated with low socioeconomic status (OR 1.409 [1.048-1.899]; p < 0.023) which affected their knowledge and health seeking behaviour in both the groups. Hence it can be concluded that empowering women in terms of education and economic status is the key factor in combating anaemia in pregnancy to prevent the vicious cycle of associated problems.

Current status of knowledge on public-speaking anxiety.

Pull, Charles B

2012-01-01

This review examines the current knowledge on public-speaking anxiety, that is, the fear of speaking in front of others. This article summarizes the findings from previous review articles and describes new research findings on basic science aspects, prevalence rates, classification, and treatment that have been published between August 2008 and August 2011. Recent findings highlight the major aspects of psychological and physiological reactivity to public speaking in individuals who are afraid to speak in front of others, confirm high prevalence rates of the disorder, contribute to identifying the disorder as a possibly distinct subtype of social anxiety disorder (SAD), and give support to the efficacy of treatment programs using virtual reality exposure and Internet-based self-help. Public-speaking anxiety is a highly prevalent disorder, leading to excessive psychological and physiological reactivity. It is present in a majority of individuals with SAD and there is substantial evidence that it may be a distinct subtype of SAD. It is amenable to treatment including, in particular, new technologies such as exposure to virtual environments and the use of cognitive-behavioral self-help programs delivered on the Internet.

Globally, the prevalence of oesophageal cancer cases is particularly high in China. Since 1982, oncogenic human papillomavirus (HPV) has been hypothesized as a risk factor for oesophageal cancer, but no firm evidence of HPV infection in oesophageal cancer has been established to date. We aimed to conduct a meta-analysis to estimate the high-risk HPV-18 prevalence of oesophageal cancer in the Chinese population. Eligible studies published from 1 January 2005 to 12 July 2014 were retrieved via computer searches of English and Chinese literature databases (including Medline, EMBASE, Chinese National Knowledge Infrastructure and Wanfang Data Knowledge Service Platform). A random-effects model was used to calculate pooled prevalence and corresponding 95% confidence intervals (CIs). A total of 2556 oesophageal cancer cases from 19 studies were included in this meta-analysis. Overall, the pooled HPV-18 prevalence in oesophageal cancer cases was 4·1% (95% CI 2·7-5·5) in China, 6·1% (95% CI 2·9-9·3) in fresh or frozen biopsies and 4·0% (95% CI 2·3-5·8) in paraffin-embedded fixed biopsies, 8·2% (95% CI 4·6-11·7) by the E6/E7 region and 2·2% (95% CI 0·9-3·6) by the L1 region of the HPV gene. This meta-analysis indicated that China has a moderate HPV-18 prevalence of oesophageal cancer compared to cervical cancer, although there is variation between different variables. Further studies are needed to elucidate the role of HPV in oesophagus carcinogenesis with careful consideration of study design and laboratory detection method, providing more accurate assessment of HPV status in oesophageal cancer.

Background The aim of the study was to measure knowledge about the symptoms, prevalence and natural history of stroke; the level of concern about having a stroke; understanding of the possibilities for preventing stroke, and the relationship between age, sex, country of origin, educational level, income, self-reported risk factors, and the above factors. Methods A random sample of households was selected from an electronic telephone directory in Newcastle and Lake Macquarie area of New South Wales, Australia, between 10 September and 13 October 1999. Within each household the person who was between 18 and 80 years of age and who had the next birthday was eligible to participate in the study (1325 households were eligible). The response rate was 62%. Results The most common symptoms of stroke listed by respondents were "Sudden difficulty of speaking, understanding or reading" identified by 60.1% of the respondents, and "paralysis on one side of body" identified by 42.0% of the respondents. The level of knowledge of the prevalence of a stroke, full recovery after the stroke, and death from stroke was low and generally overestimated. 69.9% of the respondents considered strokes as being either moderately or totally preventable. There were few predictors of knowledge. Conclusion The study suggests that educational strategies may be required to improve knowledge about a wide range of issues concerning stroke in the community, as a prelude to developing preventive programmes.

Carbon Dioxide Capture and Storage (CCS) is assumed to be one of the key technologies in the mitigation of climate change. Public acceptance may have a strong impact on the progress of this technology. Benefit perception and risk perception are known to be important determinants of public acceptance of CCS. In this study, the prevalence and effect of cognitive concepts underlying laypeople's risk perception and benefit perception of CCS were examined in a representative survey (N=654) in Switzerland. Results confirm findings from previous qualitative studies and show a quantification of a variety of widespread intuitive concepts that laypeople hold about storage mechanisms as well as about leakage and socioeconomic issues, which all appeared to influence risk perception and benefit perception. The perception of an overpressurized reservoir and concerns about diffuse impacts furthermore amplified risk perception. Appropriate images about storage mechanisms and climate change awareness were increasing the perception of benefits. Knowledge about CO2 seemed to lower both perceived benefits and perceived risks. Implications for risk communication and management are discussed.

To determine factors associated with adult squash players' protective eyewear behaviours. A survey of 303 players (aged >or =18 years) was conducted at three squash venues in Melbourne, Australia over a three week period in June 2000 to obtain information about protective eyewear use. Of 303 participants the response rate was 98.1%; 66.1% were males, with a mean age of 40.5 years. The majority (68.4%) had played squash for 10 years or more. Although 18.8% of players reported using protective eyewear, only 8.9% reported wearing approved eyewear. Both age group (p<0.05) and years of squash experience (p<0.01) were significantly associated with any eyewear use. The two main influences were personal experience of eye injuries (50.0%) and knowledge of eye injury risk (33.9%). A commonly reported barrier was restriction of vision (34.2%). These findings demonstrate a low prevalence of voluntary use of appropriate protective eyewear. Future prevention strategies incorporating education campaigns should focus on increasing players' knowledge of risks. The barriers to use and misconceptions about which types of eyewear is most protective need to be addressed as a priority.

Theileria annulata, a tick-borne apicomplexan protozoan, causes a lymphoproliferative disease of cattle with high prevalence in tropical and sub-tropical regions. Understanding the genetic diversity and structure of local populations will provide more fundamental knowledge for the population genetics and epidemics of protozoa. In this study, 78 samples of T. annulata collected from cattle/yaks representing 6 different geographic populations in China were genotyped using eight micro- and mini-satellite markers. High genetic variation within population, moderate genetic differentiation, and high level of diversity co-occurring with significant linkage disequilibrium were observed, which indicates there is gene flow between these populations in spite of the existence of reproductive and geographical barriers among populations. Furthermore, some degree of genetic differentiation was also found between samples from China and Oman. These findings provide a first glimpse of the genetic diversity of the T. annulata populations in China, and might contribute to the knowledge of distribution, dynamics, and epidemiology of T. annulata populations and optimize the management strategies for control.

There is hearsay that prevalence of hydatid disease in Khammam and Nalgonda districts of Andhra Pradesh is high. We report here a preliminary study conducted to determine the magnitude of the problem of hydatid disease and the morbidity associated with it in patients attending MGH, KMM, A.P. (rural hospital). Eleven cases were identified during the period from November 2005 to May 2006 (seven months). Pain in abdomen, mass per abdomen, loss of appetite, pregnancy complicated by cystic echinococcosis (CE), and jaundice were the main clinical symptoms and signs. Ultrasonography, detection and removal of the cysts on the operation table, microscopic examination of the aspirated hydatid fluid were confirmatory. Ziehl-Neelsen stain of the aspirated fluid revealed acid-fast scolices. Interrogation of the patients and their family members (50) revealed that there was a total lack of knowledge of dog-tapeworm-caused infection in humans. They knew 'rabies' as the only disease man gets from dogs, and tapeworms are from pork and beef.

To evaluate the prevalence of tuberculosis (TB) stigma and to determine the relation between socio-demographic characteristics and TB stigma among TB cases and their controls in Gezira State, Sudan. A case-control study design was used. New smear-positive TB patients registered in Gezira State in 2010 (n = 425) and controls who attended the same health facility for other reasons (n < 850) formed the study population. Stigma was measured using a standard modified World Health Organization TB KAP (knowledge, attitudes, practice) instrument. TB stigma did not differ between TB cases and controls; mild stigma was found in both groups. The higher degree of stigma among both groups was significantly associated with higher age, lower level of education, residence in rural areas, unemployment and poor TB awareness, while sex had no association with the degree of stigma in either group. Although TB stigma among the Gezira population was found to be mild, it can affect treatment adherence. Empowering both TB patients and communities by increasing their knowledge through proper education programmes could effectively contribute to the effort of controlling TB in the state.

Toxoplasmosis, listeriosis and cytomegalovirus (CMV) can negatively affect pregnancy outcomes, but can be prevented by simple precautions of pregnant women. Literature suggests that pregnant women are not always adequately informed by their care provider about preventable infectious diseases and most pregnant women have a low level of knowledge regarding these topics. There is not much information about the actual risk behaviour of pregnant women. The purpose of this study was to assess knowledge and risk behaviour related to toxoplasmosis, listeriosis and CMV infection prevention in pregnant women. A cross-sectional survey among pregnant women from twenty midwifery practices across the Netherlands that participated in the DELIVER study, between October 2010 and December 2010. The questionnaire items covered respondents' knowledge of preventive practices in general, risk behaviour, and sources of received information. Of the 1,097 respondents (response 66.0%), 75.3% had heard, read or seen information about toxoplasmosis, 61.7% about listeriosis and 12.5% about CMV. The majority reported having heard about these infections from their care providers or read about these in printed media or on the Internet. Respondents showed limited knowledge about preventive practices for toxoplasmosis, listeriosis or CMV infection. Regarding toxoplasmosis, risk behaviour was more prevalent among respondents who had a high level of education, had the Dutch nationality, did not take folic acid during their first trimester, and had ever worked in a children day-care setting. Regarding listeriosis, risk behaviour was more prevalent among respondents who where in their third trimester. Regarding CMV infections, risk behaviour was less prevalent among respondents who were in their third trimester of pregnancy. Of the respondents, a substantial part did not have knowledge about preventive practices to avoid listeriosis, toxoplasmosis and CMV infections during pregnancy. Many pregnant women are appropriately avoiding risk behaviour, without knowing what they are avoiding. Advising pregnant women about behaviours and life-style habits to prevent infectious diseases remains important and information about preventive practices need to be complete and adequate. However, it may be less important to give pregnant women specific infectious diseases information. More attention towards CMV is necessary.

Evidence-based guidelines for pressure ulcer prevention have been developed and promoted by authoritative organizations. However, nonadherence to these guidelines is frequently reported. Negative attitudes and lack of knowledge may act as barriers to using guidelines in clinical practice. To study the knowledge and attitudes of nurses about pressure ulcer prevention in Belgian hospitals and to explore the correlation between knowledge, attitudes, and the application of adequate prevention. A cross-sectional multicenter study was performed in a random sample of 14 Belgian hospitals, representing 207 wards. Out of that group, 94 wards were randomly selected (2105 patients). Clinical observations were performed to assess the adequacy of pressure ulcer prevention and pressure ulcer prevalence. From each participating ward, a random selection of at least five nurses completed an extensively validated knowledge and attitude instrument. In total, 553 nurses participated. A logistic regression analysis was performed to evaluate the correlation between knowledge, attitudes, and the application of adequate prevention. Pressure ulcer prevalence (Category I-IV) was 13.5% (284/2105). Approximately 30% (625/2105) of the patients were at risk (Bradenscore <17 and/or presence of pressure ulcer). Only 13.9% (87/625) of these patients received fully adequate prevention whilst in bed and when seated. The mean knowledge and attitude scores were 49.7% and 71.3%, respectively. The application of adequate prevention on a nursing ward was significantly correlated with the attitudes of the nurses (OR = 3.07, p = .05). No independent correlation was found between knowledge and the application of adequate prevention (OR = 0.75, p = .71). Knowledge of nurses in Belgian hospitals about the prevention of pressure ulcers is inadequate. The attitudes of nurses toward pressure ulcers are significantly correlated with the application of adequate prevention. No correlation was found between knowledge and the application of adequate prevention. Copyright ©2011 Sigma Theta Tau International.

Purpose The purpose of this study was to determine the influence of demographic characteristics, breast cancer knowledge, fatalistic beliefs, health beliefs, and subjective norms on Jordanian women’s intention to participate in mammography screening. Design A cross-sectional survey was used to collect data at 14 comprehensive healthcare centers in Amman and Zarqa, Jordan. A convenience sample of 142 Jordanian women 40 years of age or older with no history of breast cancer and able to read and write in Arabic participated. Methods Self-report surveys included a combination of researcher-designed and existing instruments to measure the study variables. Data were analyzed using descriptive statistics, Pearson’s correlation, t tests, and multiple logistic regression. Findings Jordanian women surveyed lacked knowledge about breast cancer. Social norms and self-efficacy highly influenced these women’s intention to engage in mammography screening. Younger women were more willing to indicate intention to engage in mammographic screening. Conclusions Self-efficacy and the social connectedness of Jordanian society, but not religious beliefs or perceived barriers to screening, influence Jordanian women’s intention to undergo mammography. Future research should examine cultural influences, rather than religious beliefs, and investigate Jordanian women’s potentially unique perspectives on barriers to actual mammography screening behavior. Clinical Relevance The prevalence of mammography screening may be enhanced by focusing interventions on Jordanian women’s support systems and empowering women by providing knowledge and skills needed to engage in the procedure.

Morocco stays far behind other countries in the domain of organ donation and transplantation. Improving the knowledge of Moroccan students, about organ donation and transplantation, can be a key factor in the development of transplant activity. The aim of this study is to evaluate the knowledge, attitudes and beliefs of students concerning organ donation and transplantation. The opinion survey was conducted in Marrakech city, with four high education structures with a pre-established questionnaire. The survey questions answered four main themes, which are: the evaluation of knowledge, the opinion and attitude of citizen, the explanation of refusal and the propositions to encourage organ donation in Morocco. Hundred percent of surveyed subjects answered the questionnaire. Among them, 40.3% were men. The middle age was 21.5 years. Out of 503 surveyed students, 89.4% were aware of organ transplant in Morocco. A quarter of students believed that removal and transplant acts were realized just in public health establishments, which have the authorization. Two persons out of 3 were able to identify transplantable organs and tissues. More than half accepted to donate their organs after death. The religious reason was in the head list of refusal determinants of organ donation after death, with a prevalence of 39.7%. Young Moroccans have limited knowledge relating to organ donation. The development of this therapy needs to establish an adequate project of information and motivation of general population. Copyright © 2015 Association Société de néphrologie.

HIV testing is important in terms of prevention and treatment. However, HIV testing rates in the Spanish general population remains low. Therefore, HIV testing promotion constitutes a key issue. A high level of knowledge about HIV/AIDS is associated with having been tested for HIV. The general aim of this study was to determine the prevalence of people who had ever been tested for HIV in Spain. The sample consisted of 1,106 participants from the general population - 60.0% females and 40.0% males - aged between 17 and 55 years old. The assessment instruments were a questionnaire on sociodemographic data and HIV testing, a scale of knowledge about STIs and HIV/AIDS, and a scale of concern about STIs/HIV. Results showed that greater knowledge about STIs and HIV was associated with a greater likelihood of being tested for HIV (OR = .77; 95.0% CI = .73-.82; p < .05). In addition, higher concern about HIV/AIDS decreased the likelihood of not having been tested for HIV (OR = .87; 95.0% CI = .83-.92; p < .05). In fact, the higher participants concern about STIs was, the lower their likelihood of not having been tested for HIV was (OR = .87; 95.0% CI = .83-.91; p < .05). It is necessary to promote HIV testing in the general population as well as to consider their socio-demographic and psychological characteristics.

Background and Objectives: Inappropriate complementary feeding is a major cause of child malnutrition and death. This study determined the complementary feeding knowledge, practices, minimum dietary diversity, and acceptable diet among mothers of under-five children in an urban Local Government Area of Lagos State, Southwest Nigeria. Methods: This descriptive cross-sectional study was conducted in Eti-Osa area of Lagos State, Nigeria. Multi-stage sampling technique was employed to select 355 mothers and infants. Data was collected using a pre-tested interviewer administered questionnaire and 24-hour diet recall was used to assess dietary diversity. Data was analyzed using Epi-Info. Results: Knowledge of complementary feeding was low (14.9%) and was associated with older mothers’ age, being married, and higher level of education. The prevalence of timely initiation of complementary feeding (47.9%), dietary diversity (16.0%) and minimum acceptable diet for children between 6 and 9 months (16%) were low. Overall, appropriate complementary feeding practice was low (47.0%) and associated with higher level of mothers’ education and occupation. Conclusions and Global Health Implications: Complementary feeding knowledge and practices were poor among mothers of under-5 especially the non-literate. Reduction of child malnutrition through appropriate complementary feeding remains an important global health goal. Complementary feeding education targeting behavioral change especially among young, single and uneducated mothers in developing countries is important to reduce child morbidity and mortality.

The design of mechanical circulatory support devices typically requires a priori knowledge of the hemodynamic requirements of their intended use. These requirements are difficult to determine because of limited clinical experience. This is especially true for the pediatric population, for whom there is a dearth of longitudinal data. This report aims to provide both engineers and physicians with benchmarks for determining the optimal flow requirements and settings for pediatric ventricular assist devices that are currently being developed. Criteria were developed on the basis of estimates derived from various sources. The potential patient population was estimated by using the prevalence of children on the heart transplant waiting list and those placed on extracorporeal membrane oxygenation. Cardiac outputs were determined for individual weights and body surface areas, using published values for healthy and sick pediatric patients. The recommended pump range was optimized to include the most patients, while considering the design constraints. This study identifies a significant population of patients who would benefit from a device providing 0.52 to 1.92 l/min.

The results presented here are part of a five-year cluster-randomised intervention trial that was implemented to understand how best to gain and sustain control of schistosomiasis through different preventive chemotherapy strategies. This paper presents baseline data that were collected in ten districts of Cabo Delgado province, northern Mozambique, before treatment. A cross-sectional study of 19,039 individuals was sampled from 144 villages from May to September 2011. In each village prevalence and intensity of S. haematobium were investigated in 100 children first-year students (aged 5-8 years), 100 school children aged 9-12 years (from classes 2 to 7) and 50 adults (20-55 years). Prevalence and intensity of S. haematobium infection were evaluated microscopically by two filtrations, each of 10 ml, from a single urine specimen. Given that individual and community perceptions of schistosomiasis influence control efforts, community knowledge and environmental risk factors were collected using a face-to-face interview. Data were entered onto mobile phones using EpiCollect. Data summary was made using descriptive statistics. Chi-square and logistic regression were used to determine the association between dependent and independent variables. The overall prevalence of urogenital schistosomiasis was 60.4% with an arithmetic mean intensity of infection of 55.8 eggs/10 ml of urine. Heavy infections were detected in 17.7%, of which 235 individuals (6.97%) had an egg count of 1000 eggs/10 ml or more. There was a significantly higher likelihood of males being infected than females across all ages (62% vs 58%; P < 0.0005). Adolescents aged 9-12 years had a higher prevalence (66.6%) and mean infection intensity (71.9 eggs/10 ml) than first-year students (63.1%; 58.2 eggs/10 ml). This is the first study in Mozambique looking at infection rates among adults. Although children had higher levels of infection, it was found here that adults had a high average prevalence and intensity of infection (44.5%; 23.9 eggs/10 ml). Awareness of schistosomiasis was relatively high (68.6%); however, correct knowledge of how schistosomiasis is acquired was low (23.2%) among those who had heard of the disease. Schistosomiasis risk behaviour such as washing (91.3%) and bathing (86.7%) in open water sources likely to be infested with host snails was high. Urogenital schistosomiasis is widespread in Cabo Delgado. In addition, poor community knowledge about the causes of schistosomiasis and how to prevent it increases the significant public health challenge for the national control program. This was the first study in Mozambique that examined infection levels among adults, where results showed that S. haematobium infection was also extremely high. Given that this controlled trial aims to understand the impact of different combinations of schistosomiasis control through treatment of communities, schools, and treatment holidays over a five-year period, these findings highlight the importance of examining the impact of different treatment approaches also in adults. The trials have been registered with the International Standard Randomised Controlled Trial registry under ISRCT 14117624 Mozambique (14 December 2015).

The aim of this study was to evaluate the prevalence of dental anomalies (DAs) in Odisha population using panoramic radiographs. In this study, 1,080 panoramic radiographs were evaluated for DAs. Dental records were reviewed for diagnostic confirmation. Anomalies related to the shape, size, position of teeth, and number of roots (supernumerary roots) were evaluated. The study results showed the prevalence of DAs to be 35.27%. The most prevalent was dilaceration, which was seen in 46.71% cases followed by peg laterals in 20.99%. Dental anomalies were present in more than one-third of the study group, which was mostly related to shape of the teeth. Early diagnosis of these DAs helps in avoiding complications. Identification of DAs requires proper examination and thereby subsequent correct diagnosis. These anomalies can pose complications in normal functioning of orofacial complex. The knowledge of the prevalence of such anomalies aids dental practitioners for a proper treatment plan.

This epidemiological study in a group of Italian children was undertaken in order to increase our knowledge of the prevalence of Molar Incisor Hypomineralisation (MIH) in different European countries. A population of school children aged 7.3 - 8.3 years, living in Lissone, Northern Italy, was examined for the presence and severity of MIH. Of a total of 227 children (113 females), 31 (13.7%) had MIH, the tooth prevalence in the permanent first molars being 5.8%. Fifteen children (6.6%) had demarcated opacities in the incisors with a tooth prevalence of 2.1%. The defects in the molars were mild with the exception of one child who had severe defects. MIH was quite common in this Italian town, and the prevalence figures were near those reported in Scandinavian countries but clearly higher than those from Dresden, Germany.

One billion of the world’s population has hypertension, resulting in four million deaths per year. Data on the prevalence of hypertension in the Arab world are very limited. This review summarizes existing knowledge regarding prevalence, awareness, and control of hypertension in Arab countries. The PubMed, Cochrane Library, Scopus, and CINAHL databases were searched for publications on HTN among Arab people from 1980 to January 2011. Only 13 studies were identified in the literature from 10 Arab countries. The overall estimated prevalence of hypertension was 29.5% (n = 45 379), which indicates a higher prevalence of hypertension among Arabs compared to people from the USA (28%) and sub-Saharan African (27.6%). Awareness of hypertension was reported for 46% of the studies and varied from 18% (Jordan) to 79.8% (Syria). The control rate varied from 56% (Tunisia) to 92% (Egypt and Syria). The prevalence of hypertension was found to increase with age, occurring more frequently in Arab women. PMID:24118852

Diabetic retinopathy is the first cause of blindness during working years. Provide knowledge of screening coverage, prevalence and level of diabetic retinopathy in patients that belong to the Cardiovascular Health Program in primary care. Analysis of retinographies performed to 9076 diabetic patients aged 61 ± 13 years (61% women) adscribed to a Cardiovascular Health program in primary care centers of South-East Metropolitan Santiago. The examination was carried out by the evaluation of retinographies by trained optometrists. The coverage of the screening program was 21%. The prevalence of sight threatening diabetic retinopathy was 3,1%. The prevalence of these entities was 45% higher in people aged between 18 and 44 years than in older people. Their prevalence in urban communities was 32% higher than in rural locations. The coverage of the screening program is low. Diabetic patients aged 18 to 44 years and those coming from urban communities have a higher prevalence of severe non-proliferative and proliferative diabetic retinopathy.

Malaria is one of the most severe global public health problems worldwide, particularly in Africa, where Nigeria has the greatest number of malaria cases. This community-based study was designed to investigate the prevalence and risk factors of malaria and to evaluate the knowledge, attitudes, and practices (KAP) regarding malaria among rural Hausa communities in Kano State, Nigeria. A cross-sectional community-based study was conducted on 551 participants from five local government areas in Kano State. Blood samples were collected and examined for the presence of Plasmodium species by rapid diagnostic test (RDT), Giemsa-stained thin and thick blood films, and PCR. Moreover, demographic, socioeconomic, and environmental information as well as KAP data were collected using a pre-tested questionnaire. A total of 334 (60.6 %) participants were found positive for Plasmodium falciparum. The prevalence differed significantly by age group (p < 0.01), but not by gender or location. A multivariate analysis showed that malaria was associated significantly with being aged 12 years or older, having a low household family income, not using insecticide treated nets (ITNs), and having no toilets in the house. Overall, 95.6 % of the respondents had prior knowledge about malaria, and 79.7, 87.6 and 95.7 % of them knew about the transmission, symptoms, and prevention of malaria, respectively. The majority (93.4 %) of the respondents considered malaria a serious disease. Although 79.5 % of the respondents had at least one ITN in their household, utilization rate of ITNs was 49.5 %. Significant associations between the respondents' knowledge concerning malaria and their age, gender, education, and household monthly income were reported. Malaria is still highly prevalent among rural Hausa communities in Nigeria. Despite high levels of knowledge and attitudes in the study area, significant gaps persist in appropriate preventive practices, particularly the use of ITNs. Innovative and Integrated control measures to reduce the burden of malaria should be identified and implemented in these communities. Community mobilization and health education regarding the importance of using ITNs to prevent malaria and save lives should be considered.

A common approach to the application of epidemiological models is to determine a single (point estimate) parameterisation using the information available in the literature. However, in many cases there is considerable uncertainty about parameter values, reflecting both the incomplete nature of current knowledge and natural variation, for example between farms. Furthermore model outcomes may be highly sensitive to different parameter values. Paratuberculosis is an infection for which many of the key parameter values are poorly understood and highly variable, and for such infections there is a need to develop and apply statistical techniques which make maximal use of available data. A technique based on Latin hypercube sampling combined with a novel reweighting method was developed which enables parameter uncertainty and variability to be incorporated into a model-based framework for estimation of prevalence. The method was evaluated by applying it to a simulation of paratuberculosis in dairy herds which combines a continuous time stochastic algorithm with model features such as within herd variability in disease development and shedding, which have not been previously explored in paratuberculosis models. Generated sample parameter combinations were assigned a weight, determined by quantifying the model's resultant ability to reproduce prevalence data. Once these weights are generated the model can be used to evaluate other scenarios such as control options. To illustrate the utility of this approach these reweighted model outputs were used to compare standard test and cull control strategies both individually and in combination with simple husbandry practices that aim to reduce infection rates. The technique developed has been shown to be applicable to a complex model incorporating realistic control options. For models where parameters are not well known or subject to significant variability, the reweighting scheme allowed estimated distributions of parameter values to be combined with additional sources of information, such as that available from prevalence distributions, resulting in outputs which implicitly handle variation and uncertainty. This methodology allows for more robust predictions from modelling approaches by allowing for parameter uncertainty and combining different sources of information, and is thus expected to be useful in application to a large number of disease systems.
