To analyze the prevalence of anemia and its proportions of severity, and to examine the association between anemia and nutritional status among Chinese students of ethnic minorities, so as to provide bases for the prevention and treatment of anemia. The subjects were Mongolian, Hui, Zhuang and Korean students aged 7, 9, 12, 14 and 17 years, sampled from the 2010 Chinese National Surveys on Students' Constitution and Health. World Health Organization (WHO) criteria for screening anemia (2001) was used, and the proportion rates of mild, moderate and severe were analyzed. The nutritional status was defined according to the growth references of body mass index (BMI)-for-age z-score for 5-19 years developed by the WHO. Stepwise Logistic regression was used to assess the association between anemia and nutritional status, gender, urban/rural areas, age and ethnic minorities. The prevalences of anemia were 4.4%, 26.4%, 6.6% and 5.8% in Mongolian, Hui, Zhuang and Korean students, respectively, of whom, the prevalence of anemia was highest in rural girls and reached 4.8%, 42.0%, 9.0% and 6.7%, respectively. Most of the ethnic minorities' students belonged to mild anemia, and the prevalence of severe anemia was 1.4%, 12.9%, 1.6% and 1.9% in Mongolian, Hui, Zhuang and Korean students, respectively. Stepwise Logistic regression showed that the girls, rural students, students aged 12 years and 17 years, Hui, Zhuang and Korean students were more likely to develop anemia than the boys, urban students, students aged 7 years and Mongolian students. The overweight students were less likely to develop anemia compared with the normal students and there was no significant association between anemia and thinness or obesity when the other factors were controlled (P>0.05). The epidemic of anemia was different in the different ethnic minorities and the prevalence of anemia in Hui students was of moderate public health concern according to the WHO's criteria. We should pay more attention to the prevention and treatment of anemia for Hui and ethnic minorities in rural areas, especially for rural girls. The nutritional status of students could not be a basis or judgement for anemia as there was no significant association between anemia and nutritional status.

To assess whether the density of alcohol sales outlets in specific geographic communities is associated with adolescent alcohol consumption. A cross-sectional representative sample of secondary school students from Victoria, Australia (N=10,143), aged between 12 and 17 years, self-reported on alcohol use in the last 30 days in 2009. The density of alcohol outlets per local community area was merged with this information. After controlling for risk factors, multilevel modelling (MLM) revealed a statistical interaction between age and density on alcohol consumption. While older adolescents had higher alcohol consumption, increases in the density of alcohol outlets were only significantly associated with increased risk of alcohol consumption for adolescents between the ages of 12 and 14. Increased alcohol availability was associated with an increased risk of alcohol consumption specifically for early adolescents (12 and 14 years). Potential mechanisms as to how density is associated with direct and indirect alcohol availability, such as through parents or older siblings, need to be explored in future research. © 2013 Elsevier Ltd.

To determine the prevalence of arterial hypertension, and cardiovascular and metabolic risk factors in school students, college students and women from community-based organizations (CBO) in four districts in Peru. Cross-sectional study conducted in 2011 in the districts of Lima, Callao, La Libertad and Arequipa with school students, university students and women from CBOs. A survey, anthropometric measurements, blood pressure measurements and fasting blood sampling were conducted to determine glucose and lipid levels. Thus, prevalence of overweight, hypertension, hypercholesterolemia, suspected diabetes, and other variables, were calculated. The main outcome variable was prevalence of overweight. 1,127 people were included: 283 (25.1%) school students, 431 (38.3%) university students, and 413 women (36.6%) from CBOs. Non-response rates were 3%, 0% and 8%, respectively. The average ages in the three groups were 14.3 ± 0.9; 19.6 ± 2.8; and 46.1 ± 15.3 years, respectively. Prevalence of overweight/obesity (BMI ≥ 25) was 11.3%, 20.9%, and 73.4%; hypertension was 0.7%; 1.2%, and 12.8%; high cholesterol (≥ 200 mg/dL) was 5.2%, 11.5%, and 50.1%; and suspected diabetes was 1.4%; 1.0%, and 20.3% respectively in each group of school students, university students and women from CBOs. The prevalence of cardiovascular and metabolic risk factors generally increased in older age groups. In school and university aged groups, the most frequent problems were overweight and obesity, particularly abdominal obesity.

In a sample of 527 academically at-risk youth, we investigated trajectories of friends' and parents' school involvement across ages 12–14 and the joint contributions of these trajectories to adolescents' age 15 school engagement and academic achievement. Girls reported higher levels of friends' and parents' school involvement than boys. Both parents' and friends' school involvement declined across ages 12–14. Combined latent growth models and structural equation models showed effects of the trajectories of friends' and parents' school involvement on adolescents' age 15 school engagement and academic achievement, over and above adolescents' prior performance. These effects were additive rather than interactive. Strategies for enhancing parent involvement in school and students' affiliation with peers who are positively engaged in school are discussed.

Sexual behavior, use of contraceptive methods and risk factors for HPV infections of students living in central Italy: implications for vaccination strategies.

2012-03-01

The most frequent risk factors related to the infection/persistence of HPV in the population are an early start of sexual activity, the number of sexual partners, smoking, and the utilization of some contraceptive methods. In Italy, HPV vaccine is offered free of charge to all 12-year-old female adolescents, with a possible extension to other age groups according to Regional policies. In order to value the suitability of the current HPV vaccination strategies in Italy, an epidemiological study on sexual habits in adolescents and young adults was organized. An anonymous questionnaire on sexual behavior and risk factors for HPV infection was administered to 2300 students aged 13-24 years attending secondary schools and universities in Tuscany during 2008-09. About 12% of the sample declared to be foreign citizen. The results highlight the early start of sexual activity among young students. Particularly, more than half of the interviewed students declared to be already sexually active. The mean and the median age of the first sexual intercourse was 15.4 +/- 1.4 years and 15 years (25th and 75th percentiles = 14-16), respectively. More than 77% of students at age 16 years declared they already had the first sexual intercourse, compared with 0.3% of those <12 years. Generally, females aged 13-16-years, if sexually active, had sexual contacts with a single partner. Most students declared to know common contraceptive methods (male condom and contraceptive pill). However, only half of them declared a regular use of male condom. These data confirm the importance of vaccination against HPV for young females before their sexual debut. In addition, the current multi-cohort strategy of HPV vaccination in Tuscany (free of charge in the age range 12-16 years) allows also to catch up those girls that have not yet had their first sexual experiences before 16 years (21.5% according to our study) but also to those girls already sexually active, who very rarely are already infected by all vaccine types at 16 years. Our results also show the importance of sexual health education and of promotion of correct behaviours in schools.

Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students at risk of later psychiatric events. Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves for unadjusted associations and multivariable cause-specific Cox proportional hazard analyses for adjusted hazard ratios (HRs). We identified 12,147 healthy students with exam-related beta-blocker use and 12,147 matched healthy students with no current or prior use of beta-blockers (median age, 19 years; 80.3% women). Among all healthy students, 0.14% had a first-time prescription for a beta-blocker during the exam period with the highest proportion among students aged 19 years (0.39%). Eighty-one percent of the students filled only that single prescription for a beta-blocker during follow-up. During follow-up, 2225 (18.3%) beta-blocker users and 1400 (11.5%) nonbeta-blocker users were prescribed an antidepressant (p < 0.0001); 1225 (10.1%) beta-blocker users and 658 (5.4%) nonbeta-blocker users were prescribed a psychotropic drug (p < 0.0001); and 16 (0.13%) beta-blocker users and 6 (0.05%) nonbeta-blocker users attempted suicide (p = 0.03). Exam-related beta-blocker use was associated with an increased risk of antidepressant use (adjusted HRs, 1.68 [95% confidence intervals (CIs), 1.57-1.79], p < 0.0001), other psychotropic medication use (HR, 1.93 [95% CI, 1.76-2.12] p < 0.0001), and suicide attempts (HR, 2.67 [95% CI, 1.04-6.82] p = 0.04). In healthy students, use of beta-blockers during the exam period was associated with an increased risk of psychiatric outcomes and might identify psychologically vulnerable students who need special attention.

2003-12-01

The present study examined effects of sex, attitude towards physical activity, perceived barriers for participation in physical activity, and students' perception of their parents' participation in physical activity on the intrinsic motivation of students participating in a health related program in physical education. 643 students (303 boys and 340 girls) responded to questionnaires measuring intrinsic motivation, attitudes towards physical activity, perceived barriers to exercise and perceived parents' participation in physical activity. Mean age was 12.9 yr. (SD=1.2, range 11-14 years). Analysis indicated that students' intrinsic motivation towards the program was influenced by perceived barriers to exercise. Sex, attitudes towards physical activity, and perceived parents' participation in physical activity seem to be less important.

To update the prevalence of overweight and obesity in children and adolescents from 2015. Data for this study were obtained from children and adolescents aged 7-17 years with measured weight and height from the National Surveys on Chinese Students' Constitution and Health in 2015. Measurements from 29 418 children and adolescents (14 480 boys and 14 938 girls) were analysed. Among children and adolescents aged 7-17 years, the prevalence of obesity was 13.2% (95% CI = 12.8-13.7%) in 2015. Moreover, the prevalence of obesity for children aged 7-12 years (20.3% (95% CI = 19.5-21.1%)) was significantly higher than in adolescents aged 13-17 years (9.6% (95% CI = 9.2-10.0%)) (p < 0.001). Obesity was much worse in children than adolescents in China; future studies are warranted to understand why these differences may be occurring.

To determine whether family structure (polygamous or monogamous) is associated with sexual activity among school students in Nigeria. Cross sectional school survey with a two stage, clustered sampling design. 4218 students aged 12-21 years attending 39 schools in Plateau state, Nigeria. Responses from 2705 students were included in the analysis. Report of ever having had sexual intercourse. Variables of interest included sexual history, age, sex, religion, family polygamy, educational level of parents, having a dead parent, and sense of connectedness to parents and school. Overall 909 students (34%) reported ever having had sexual intercourse, and 1119 (41%) reported a polygamous family structure. Sexual activity was more common among students from polygamous families (42% of students) than monogamous families (28%) (chi2=64.23; P<0.0001). Variables independently associated with sexual activity were male sex (adjusted odds ratio 2.52 (95% confidence interval 2.05 to 3.12)), older age (1.62 (1.24 to 2.14)), lower sense of connectedness with parents (1.87 (1.48 to 2.38)), having a dead parent (1.59 (1.27 to 2.00)), family polygamy (1.58 (1.29 to 1.92)), lower sense of connectedness with school (1.25 (1.09 to 1.44)), and lower educational level of parents (1.14 (1.05 to 1.24)). Multistep logistic regression analysis showed that the effect of polygamy on sexual activity was reduced by 27% by whether students were married and 22% by a history of forced sex. Secondary school students in Nigeria from a polygamous family structure are more likely to have engaged in sexual activity than students from a monogamous family structure. This effect is partly explained by a higher likelihood of marriage during adolescence and forced sex. Students' sense of connectedness to their parents and school, regardless of family structure, decreases the likelihood of sexual activity, and fostering this sense may help reduce risky sexual behaviour among Nigerian youth.

Unwanted Sexual Experiences in Young Men: Evidence from a Survey of University Students in Chile

2012-01-01

The public health problem of unwanted sexual experiences (USE) in male youths has received little attention. In this study, we examined prevalence of USE, risk factors, contexts, and barriers to disclosure with data from a quantitative survey of students enrolled in General Education courses at a public university in Chile. This study focused on the male sample (N = 466). Approximately 20.4% of participants reported some form of USE since age 14. Forced sex through physical coercion, forced sex through verbal coercion or while intoxicated, attempted forced sex, and less severe forms of USE were reported by 0.2%, 10.1%, 1.4%, and 8.7% of participants, respectively. USE before age 14 was reported by 9.4% of participants and was a significant predictor of USE since age 14 (AOR 6.38, 95% CI 3.22–12.65, p < .01). The perpetrator of USE since age 14 was most commonly identified as a date/partner or friend/acquaintance; other findings on contexts and barriers to disclosure were also generally consistent with previous results in the literature. In addition, we found substantial co-occurrence of USE since age 14 with two other forms of coercion: physical dating violence victimization and coerced condom non-use. The study findings indicate a need for further attention to these public health problems and have implications for the development of violence and HIV/STI prevention programs for adolescent boys and young adult men in Chile and elsewhere.

Insufficient sleep among children and adolescents is associated with increased risk for obesity, diabetes, injuries, poor mental health, attention and behavior problems, and poor academic performance (1-4). The American Academy of Sleep Medicine has recommended that, for optimal health, children aged 6-12 years should regularly sleep 9-12 hours per 24 hours and teens aged 13-18 years should sleep 8-10 hours per 24 hours (1). CDC analyzed data from the 2015 national, state, and large urban school district Youth Risk Behavior Surveys (YRBSs) to determine the prevalence of short sleep duration (<9 hours for children aged 6-12 years and <8 hours for teens aged 13-18 years) on school nights among middle school and high school students in the United States. In nine states that conducted the middle school YRBS and included a question about sleep duration in their questionnaire, the prevalence of short sleep duration among middle school students was 57.8%, with state-level estimates ranging from 50.2% (New Mexico) to 64.7% (Kentucky). The prevalence of short sleep duration among high school students in the national YRBS was 72.7%. State-level estimates of short sleep duration for the 30 states that conducted the high school YRBS and included a question about sleep duration in their questionnaire ranged from 61.8% (South Dakota) to 82.5% (West Virginia). The large percentage of middle school and high school students who do not get enough sleep on school nights suggests a need for promoting sleep health in schools and at home and delaying school start times to permit students adequate time for sleep.

2010-01-01

The study describes the prevalence of different forms of smoking, and the correlates of current smoking, by male students of King Faisal University, Saudi Arabia. A random sample of 1382 students at 9 colleges answered a self-administered questionnaire based on the Global Youth Tobacco Survey plus the modified Fagerström Test for Nicotine Dependence. The prevalence of current smoking was 28.1% (21.6% for cigarettes, 14.6% for waterpipe). Of current smokers, 41.4% were living in homes where others smoke and 17.0% initiated smoking below age 12 years. In logistic regression analysis older age, living away from home, smoking by family and close friends and exposure to tobacco promotion were predictors of current smoking status.

[Acceptance of a total smoking ban in schools: students' attitudes].

Morgenstern, M; Wiborg, G; Hanewinkel, R

2008-06-01

The purpose of this study was to measure students' attitudes towards a total smoking ban in schools and towards impositions in cases of violation. Cross-sectional survey of 1 738 students of 12 public schools in Schleswig-Holstein (grades 7-13, age 11-20 years). Data were collected by means of written questionnaires administered during class time. The following variables were assessed: attitude towards smoking ban, attitude towards impositions, age, sex, citizenship, perceived school climate, current smoking, lifetime smoking; for smokers, and additionally, the "Heaviness of Smoking Index". 76.5% of all students agreed with a total smoking ban, 66.4% agreed with the punishment of violations. Higher acceptance rates were found among girls, young students (11-15 years of age), for never-smokers, and for students who feel comfortable at school. Acceptance of the smoking ban is closely related to current smoking status: 93% of the non-smoking students, but only 14% of the daily smoking students agreed with the regulations. Refusal of the ban increased with increasing physical dependence. The intensification of the smoking ban in public schools meets approval by the majority of students. Smoking students should be more strongly involved in the implementation process, e.g., by supplemental cessation programmes.

Some local governments have implemented strategies to increase physical activity as a way to control obesity in children, but in Iranian students few studies have evaluated the effects of such interventions on overweight and obese children. The aim of this study was to evaluate the effects of a short-term school-based physical activity on obesity and cardiovascular fitness in 12-14-year-old boy students. This study showed an intervention effect on some health-related fitness factors in students. A number of 127 boy students aged 12-14 years, in the city of Isfahan, based on preventive plan of inactivity in children at the provincial Health office selected randomly as subjects. Measurement variables include; weight, height, body mass index (BMI), waist-hip ratio (WHR), body-fat percent and aerobic power of subjects measured by valid tests. This study revealed that body-fat percentage of this students changed near to 17.84% (42.25% pretest vs. 34.71% posttest), WHR 0.44%, (0.915 pretest vs. 0.911 posttest), VO2 max changed 8.54% (27.84 pretest vs. 30.22 posttest) whereas BMI was changed 2.61% (26.81 pretest vs. 26.03 posttest). Results also revealed that there were significant differences between fat percent, (P = 0.001) and VO2 max (P = 0.001), but there was no difference between BMI of subjects in pre and posttests (P = 0.452). Findings of this study signify that an implementation of short-term intervention components in the school system may have a beneficial effect on body-fat percentage and cardiovascular fitness of overweight/obese children.

According to the 2010 estimates by the World Health Organization, nearly 285 million (4.24% of total population) people of all ages worldwide are visually impaired. Almost 18.9 million children under 15 years of age are visually impaired globally. In developing countries, 7%-31% of childhood blindness and visual impairment is avoidable. The study was conducted as a cross-sectional study among 1884 school students in Puducherry, in the age group of 10-14 years. A child with presenting maximum vision ≤6/12 Snellen equivalent in the better eye is considered visually impaired. Data were entered in Microsoft Excel 2013 and analyzed using the statistical software SPSS version 21.0. Chi-square test was applied for testing difference in proportion and a P < 0.05 was considered statistically significant. The overall prevalence of visual impairment (vision ≤6/12) among the study participants was 6.37% (95% confidence interval = 5.27-7.47). The prevalence of visual impairment increased with age and it was found to be high among male students (6.6%) when compared to female students (6%). Presenting vision of 6/6 was observed in 79.8% of the children while with pinhole correction, the proportion increased to 94.6%. The prevalence of visual impairment in our study population was found to be 6.37% and the prevalence was even higher among children who belonged to schools of urban region or private schools. Children with a positive family history of spectacle use were more likely to have visual impairment.

Science-related Aspirations Across the Primary-Secondary Divide: Evidence from two surveys in England

Students' engagement with science and the numbers pursuing further study of science continue to be a concern among policy-makers, particularly in Western countries. Previous research reflects that most children have positive attitudes to science at age 10 but that, by age 14, attitudes towards and interest in further pursuit of science have declined. The Science Aspirations and Career Choice (ASPIRES) project, a 5-year longitudinal study, seeks to trace and track changes in students' interest in science and in scientific careers over the key period of ages 10-14. Building on an initial survey (consisting primarily of Likert-type items) of over 9,000 children in their last year of primary school, we explore shifts in attitudes and aspirations in science as reflected in a second survey of students from this cohort (over 5,600 students), completed when children were in their second year of secondary school (ages 12-13). Survey findings are supplemented by longitudinal interview data from 85 children. Contrary to previous research, descriptive, multivariate and multi-level modelling (MLM) analyses of the data indicate that the majority of our sample enjoy school science in secondary school and hold positive views of scientists. However, as with the primary school data, these positive attitudes also continue not to translate into an interest in 'being' a scientist. Attention is drawn to the importance of families and student experiences of school science in helping to explain this gap.

Objective To identify prevalence of previous blood pressure measurement and analyze some associated factors in adolescents. Methods This cross-sectional study included 6,077 adolescents aged 14 to 19 years. Demographic characteristics included (sex, age, period of study, region of residence, work, skin color, and economic) status, history of blood pressure measurement within last 12 months, local of blood pressure measurement, and reading obtained. To assess associations between previous blood pressure measurement with demographic characteristics and high blood pressure we used descriptive statistics and logistic regression analysis. Results Out of the adolescents, 56.8% reported no blood pressure measurement within the last 12 months. The health centers and the physician’s office were most mentioned places for blood pressure measurement (28.3% and 36.9%, respectively). Boys (odds ratio of 1.64 95%CI: 1.46-1.84) aged 14 to 16 years (odds ratio of 1.12; 95%CI: 1.01-1.25), whose economic status was unfavorable (odds ratio of 1.48; 95%CI: 1.32-1.67) were significantly associated with no blood pressure measurement. Working was a protective factor for was not blood pressure measurement (odds ratio of 0.84; 95%CI: 0.73-0.97). Conclusion Most of adolescents did not have their blood pressure measured within the last 12 months. Boys aged 14 to 16 years and those with unfavorable economic status had higher chance of not having their blood pressure measured. PMID:26466061

The present study is first of its kind to evaluate causes of visual impairment of blind students in Nepal and assess their need for low vision rehabilitation services. To evaluate causes of vision impairment of students enrolled in blind schools in Nepal and assess the need for low vision rehabilitation services in these students. A survey was conducted in 12 blind schools in Nepal, which were registered with Nepal Association for Welfare of Blindness (NAWB).It was conducted by a team of an ophthalmologist and an optometrist, by using standard eye examination protocols of the World Health Organization Prevention of Blindness Program (WHO/PBL). Of the 345 students enrolled in 12 schools, 285 students were examined (response rate of 82.61%). The students were in the 5 - 29 years age group. Nearly three-fourth of the children had become blind within one year of age and 52.3% visually impaired at birth and 20.7% developed vision impairment within one year of age. After refraction, 26 students (9.12%) had mild visual impairment, 21 students (7.37%) had severe visual impairment and 238 students (83.51%) were blind. The main cause of vision impairment was found to be corneal 35.79% and retina diseases, mainly dystrophy, 20.35% followed by problems with the whole globe, lens and optic nerve, accounting for 13.33%, 12.63% and 12.98% respectively. The major etiological factors were those of childhood such as Vitamin A deficiency, measles and similar causes (42.11%) followed by hereditary causes (25.26%). Of the total students examined, 48.07% were visually impaired due to preventable causes and 16.14% treatable aggregating to 64.21% of avoidable blindness. Fifty seven (28.22%) students could read smaller than 2 M print size after low vision assessment for near and 33(15.78%) students benefited with telescopic trial for distance low vision. In Nepal, renewed focus on providing best possible quality of life for visually impaired children by proper low vision assessment and eye health education focusing on, general public and community health workers, with governmental and institutional support is required to achieve Vision 2020 objectives to decrease childhood blindness.

Women have higher rates of auditory verbal hallucinations (AVH) than men; however, less is known about sex differences in the prevalence of AVH in early, middle and late adolescence. We sought to elucidate the differences in the prevalence of AVH and to examine the degree to which these differences could be explained by differences in levels of depressive symptoms. We used a cross-sectional design and a self-reported questionnaire. Participants were recruited from public junior and senior high schools in Tsu, Mie Prefecture and Kochi Prefecture, Japan. In total, 19 436 students were contacted and 18 250 participated. Responses from 17 451 students with no missing data were analysed (aged 12-18 years, M age =15.2 years (SD=1.7), 50.6% girls). AVH were assessed through one of four items adopted from the schizophrenia section of the Japanese version of the Diagnostic Interview Schedule for Children. Depressive symptoms were assessed using the 12-item General Health Questionnaire. The prevalence of AVH was 7.0% among early adolescents (aged 12-13 years), 6.2% among middle adolescents (aged 14-15 years) and 4.8% among late adolescents (aged 16-18 years). Being female was significantly associated with a higher prevalence of AVH through adolescence (OR=1.71, 95% CI 1.31 to 2.23 in early adolescence; OR=1.42, 95% CI 1.14 to 1.76 in middle adolescence; OR=1.52, 95% CI 1.23 to 1.87 in late adolescence); however, these differences became non-significant after adjusting for depressive symptoms (OR=1.21, 95% CI 0.92 to 1.60; OR=1.00, 95% CI 0.80 to 1.25; OR=1.16, 95% CI 0.93 to 1.44, respectively). Sex differences in auditory hallucinations are seen in both adult and youth populations. The higher rates of auditory verbal hallucinations seen in girls may be secondary to the differences in the rate of depressive symptoms. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2013-11-09

Dental caries remains one of the most common chronic diseases of adolescents. In Australia there have been few epidemiological studies of the caries experience of adolescents with most surveys focusing on children. The New South Wales (NSW) Teen Dental Survey 2010 is the second major survey undertaken by the Centre for Oral Health Strategy. The survey is part of a more systematic and efficient approach to support State and Local Health District dental service planning and will also be used for National reporting purposes. Data for the NSW Teen Dental Survey were collected in 2010 from a random sample of Year 9 secondary school students aged 14 to 15 years from metropolitan and non-metropolitan schools under the jurisdiction of the NSW Department of Education and Training, the Catholic Education Commission and Independent Schools in New South Wales. Nineteen calibrated examiners performed 1269 clinical examinations at a total of 84 secondary schools across NSW. The survey was accompanied by a questionnaire looking at oral health related behaviours, risk factors and the usage of the Medicare Teen Dental Plan. 175 schools were contacted, with 84 (48%) accepting the invitation to participate in the study. A total of 5,357 student consent forms and parent information packages were sent out and 1,256 students were examined; leading to a student participation rate of 23%. The survey reported a mean DMFT for 14 and 15 year olds of 1.2 and it was identified that 45.4% of students had an experience of dental caries. Major variations in caries experience reported occurred by remoteness, water fluoridation status, socio-economic status and household income levels. The NSW Teen Dental Survey provided state-wide data that will contribute to the national picture on adolescent oral health. The mean DMFT score of 1.2 is similar to the national caries experience data for this age group from the Australian Child Dental Health Survey in 2009.

The aim of this study was to evaluate the comparative status of oral health practices, oral hygiene, and periodontal status amongst visually impaired and sighted students. In this study, 142 visually impaired children from a blind school in the age group of 6-18 years were enrolled with a similar number of age and sex matched sighted students studying in different schools of Chandigarh. The outcome variables were oral hygiene practices, oral hygiene status, and periodontal status. The visually impaired had been found to have better oral hygiene practices, a nonsignificant difference of oral hygiene scores but a significantly high value for bleeding scores as compared to sighted students. Age wise comparisons showed that bleeding scores were highly significant in 9-11 years and 12-14 years age group as compared to 6-8 years and 15-18 years age group. It could be related that the increased prevalence of bleeding sites despite of better oral hygiene practices in visually impaired group might be the result of their handicap to visualize plaque. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

Logar, Ana; Peklaj, Cirila; Ferk Savec, Vesna

2017-09-01

The aim of the research was to optimize the effectiveness of student learning based on experimental work in chemistry classes in Slovenian primary schools. To obtain evidence about how experimental work is implemented during regular chemistry classes, experimental work was videotaped during 19 units of chemistry lessons at 12 Slovenian primary schools from the pool of randomly selected schools. Altogether 332 eight-grade students were involved in the investigation, with an average age of 14.2 years. Students were videotaped during chemistry lessons, and their worksheets were collected afterward. The 12 chemistry teachers, who conducted lessons in these schools, were interviewed before the lessons; their teaching plans were also collected. The collected data was analyzed using qualitative methods. The results indicate that many teachers in Slovenian primary schools are not fully aware of the potential of experimental work integrated into chemistry lessons for the development of students' experimental competence. Further research of the value of different kinds of training to support teachers for the use of experimental work in chemistry teaching is needed.

Background Adolescent substance use is associated with lower educational achievement but the directionality of the association remains uncertain. We analyzed data on drinking, smoking and educational achievement to study the associations between substance use and education from early adolescence to young adulthood. Methods Longitudinal data from four time points (ages 12, 14, 17, and 19-27 years) from a population-based cohort study of Finnish twin individuals were used to estimate bivariate cross-lagged path models for substance use and educational achievement, adjusting for sex, parental covariates, and adolescent externalizing behavior. A total of 4,761 individuals (49.4% females) were included in the analyses. Educational achievement was assessed with teacher-reported grade point average at ages 12 and 14, and with self-reported student status and completed education at age 17 and in young adulthood. From self-reported questionnaire items, frequency of any drinking, frequency of drinking to intoxication, any smoking and daily smoking were analyzed. Results Alcohol use and smoking behaviors at ages 12 and 14 predicted lower educational achievement at later time points even after previous achievement and confounding factors were taken into account. Lower school achievement in adolescence predicted a higher likelihood of engaging in smoking behaviors but did not predict later alcohol use. Higher educational attainment at age 17 predicted more frequent drinking in young adulthood. Conclusions Adolescent drinking behaviors are associated with lower future educational achievement independently of prior achievement, whereas smoking both predicts and is predicted by lower achievement. Early substance use indexes elevated risk for poor educational outcomes. PMID:24548801

To study or to sleep? The academic costs of extra studying at the expense of sleep.

Gillen-O'Neel, Cari; Huynh, Virginia W; Fuligni, Andrew J

2013-01-01

This longitudinal study examined how nightly variations in adolescents' study and sleep time are associated with academic problems on the following day. Participants (N = 535, 9th grade M(age) = 14.88) completed daily diaries every day for 14 days in 9th, 10th, and 12th grades. Results suggest that regardless of how much a student generally studies each day, if that student sacrifices sleep time to study more than usual, he or she will have more trouble understanding material taught in class and be more likely to struggle on an assignment or test the following day. Because students are increasingly likely to sacrifice sleep time for studying in the latter years of high school, this negative dynamic becomes increasingly prevalent over time. © 2012 The Authors.

To compare baseline scores of middle and high school students on the Sport Concussion Assessment Tool 2 (SCAT2) by sex and age. Cross-sectional study. Single private school athletic program. Three hundred sixty-one middle and high school student-athletes. Preseason SCAT2 was administered to student-athletes before athletic participation. Total SCAT2 score, symptoms, symptom severity, Glasgow coma scale, modified Balance Error Scoring System (BESS), coordination, and Standardized Assessment of Concussion (SAC) with subsections: Orientation, Immediate Memory, Concentration, and Delayed Recall. No differences were found in total SCAT2 scores between sex (P = 0.463) or age (P = 0.21). Differences were found in subcomponents of the SCAT2. Twelve year olds had significantly lower concentration scores (3.3 ± 1.2) than 15 and 18 year olds (3.9 ± 1.0 and 4.2 ± 1.0, respectively). The 12 year olds also had the lowest percentage of correct responses for the SAC's concentration 5-digit (46%), 6-digit (21%), and months' backward (67%) tasks. Females presented with more symptoms (20.0 ± 2.2 vs. 20.6 ± 2.1 P = 0.007) better immediate memory (14.6 ± 0.9 vs. 14.3 ± 1.0, P = 0.022) and better BESS scores (27.2 ± 2.3 vs. 26.6 ± 2.6, P = 0.043) than their male counterparts. Normative values for total SCAT2 and subscale scores show differences in concentration between ages, whereas symptoms, BESS, and immediate memory differed between sexes. We also found that 12 year olds have increased difficultly with the advanced concentration tasks, which lends support to the development of a separate instrument, such as the Child-SCAT3. The presence of developmental differences in the younger age groups suggests the need for annual baseline testing. Subtle differences between age and sex have been identified in many components of the SCAT2 assessment. These differences may support the current evolution of concussion assessment tools to provide the most appropriate test. Baseline testing should be used when available, and clinicians should be aware of potential differences when using normalized values.

Due to a problem of identification, how to estimate the distinct effects of age, time period and cohort has been a controversial issue in the analysis of trends in health outcomes in epidemiology. In this study, we propose a novel approach, partial least squares (PLS) analysis, to separate the effects of age, period, and cohort. Our example for illustration is taken from the Glasgow Alumni cohort. A total of 15,322 students (11,755 men and 3,567 women) received medical screening at the Glasgow University between 1948 and 1968. The aim is to investigate the secular trends in blood pressure over 1925 and 1950 while taking into account the year of examination and age at examination. We excluded students born before 1925 or aged over 25 years at examination and those with missing values in confounders from the analyses, resulting in 12,546 and 12,516 students for analysis of systolic and diastolic blood pressure, respectively. PLS analysis shows that both systolic and diastolic blood pressure increased with students' age, and students born later had on average lower blood pressure (SBP: −0.17 mmHg/per year [95% confidence intervals: −0.19 to −0.15] for men and −0.25 [−0.28 to −0.22] for women; DBP: −0.14 [−0.15 to −0.13] for men; −0.09 [−0.11 to −0.07] for women). PLS also shows a decreasing trend in blood pressure over the examination period. As identification is not a problem for PLS, it provides a flexible modelling strategy for age-period-cohort analysis. More emphasis is then required to clarify the substantive and conceptual issues surrounding the definitions and interpretations of age, period and cohort effects. PMID:21556329

2009-03-01

This study applied self-determination theory to investigate the effects of students' autonomous motivation and their perceptions of teacher autonomy support on need satisfaction adjustment, learning achievement, and cardiorespiratory fitness over a 4-month personal conditioning unit. Participants were 253 urban adolescents (121 girls and 132 boys, ages = 12-14 years). Based on a series of multiple regression analyses, perceived autonomy support by teachers significantly predicted students'need satisfaction adjustment and led to learning achievement, especially for students who were not autonomously motivated to learn in physical education. In turn, being more autonomous was directly associated with cardiorespiratory fitness enhancement. The findings suggest that shifts in teaching approaches toward providing more support for students' autonomy and active involvement hold promise for enhancing learning.

This study aimed to (1) evaluate the gap filling skills and reading mistakes of students with cochlear implants, and to (2) compare their results with those of their normal-hearing peers. The effects of implantation age and total time of cochlear implant use were analyzed in relation to the subjects' reading skills development. The study included 19 students who underwent cochlear implantation and 20 students with normal hearing, who were enrolled at the 6th to 8th grades. The subjects' ages ranged between 12 and 14 years old. Their reading skills were evaluated by using the Informal Reading Inventory. A significant relationship were found between implanted and normal-hearing students in terms of the percentages of reading error and the percentages of gap filling scores. The average order of the reading errors of students using cochlear implants was higher than that of normal-hearing students. As for the gap filling, the performances of implanted students in the passage are lower than those of their normal-hearing peers. No significant relationship was found between the variables tested in terms of age and duration of implantation on the reading performances of implanted students. Even if they were early implanted, there were significant differences in the reading performances of implanted students compared with those of their normal-hearing peers in older classes.

2011-05-01

The present study aims to analyze the psychometric properties of the student form (Grades 7 to 12) of the Social Skills Questionnaire authored by Gresham and Elliott (1990), on a sample of Portuguese adolescents. Participants included 573 students, both female and male, aged 14 to 19. Reliability was assessed through Cronbach's alpha and was .87 for the total scale, ranging from.58 to .72 for the subscales. A confirmatory factor analysis revealed that the main adjustment indices presented unexpected values. A principal components analysis indicated that several items of the cooperation subscale correlated with other factors. Adequate adjustment indices were found when cooperation was removed from the model. Semantic dualities due to cultural factors and difficulties assuming the cooperation dimension as an independent dimension might explain the results observed. The reorganization of the SSQ offers a reliable and valid instrument for research within the Portuguese population.

To analyze the prevalence and symptoms of asthma in students of the Brazilian Amazon municipality of Alta Floresta-MT. Cross-sectional study on the prevalence of asthma in 6 and 7 year-old children and 13 to 14 year-old adolescents, using the Study of Asthma and Allergies in Childhood - ISAAC method, phase I in 2007. Students who answered affirmatively question 2 - "presence of wheezing in the past 12 months" were considered asthmatic. Of the total 2,071 students, 1,072 (51.7%) were children and 999 (48.3%) were teenagers. The prevalence of asthma was 21.4% among schoolchildren, and 12.4% among adolescents (chi2 = 29.29; rho = 0.00). Children presented a higher prevalence than adolescents of the following asthma symptoms: wheezing sometime in life (49.9%), wheezing in the past 12 months (21.4%), 1 to 3 wheezing attacks in the past 12 months (16.4%), and dry cough at night (38.2%). Regarding physician-diagnosed asthma, no difference was observed between the two age groups, with a prevalence of around 6.0%. Male schoolchildren presented a higher prevalence of asthma, physician-diagnosed asthma and four or more wheezing episodes in the past 12 months (rho < 0.05). Male adolescents presented the highest prevalence of strong wheezing affecting speech (rho < 0.05). Alta Floresta presents one of the highest prevalences of asthma in Latin America among schoolchildren in the 6 and 7 year-old age group.

2017-02-21

A cross-sectional study was performed on a student population in grades 7-12 in 10 private schools in Dubai in the academic year 2012/13. The study was in two phases. The first was used to estimate incidence rate of injuries, where the total injuries that took place in the schools in 2012 was divided by the total student population in the studied schools in the same year multiplied by 1000. The second was to study the determinants of severity through randomly selecting 1000 cases of injuries. A self-administered questionnaire was given to the participants after obtaining verbal consent. Sociodemographic characteristics showed that most (74.2%) of the students in this study were male and about half (57.3%) were aged 12-14 years. The incidence rate of injuries was 297.7/1000, and most of the injuries (88.9%) were mild. Poor school safety was blamed for most of the injuries, and falls were the most frequent type of injury.

The aim of this study was to assess suicidal ideation and associated factors in school-going adolescents in the Association of Southeast Asian Nations (ASEAN) member states. The analysis included 30,284 school children aged 13-15 years from seven ASEAN countries that participated in the cross-sectional global school-based student health survey (GSHS) between 2007 and 2013. The overall prevalence of suicidal ideation in the past 12 months across seven ASEAN countries was 12.3%, significantly higher in girls (15.1%) than boys (9.3%). Among seven ASEAN countries with the highest prevalence of suicidal ideation was in the Philippines (17.0%) and Vietnam (16.9%) and the lowest in Myanmar (1.1%) and Indonesia (4.2%). In multivariable logistic regression analysis, female gender, older age (14 or 15 years), living in a lower middle income country, having no friends, loneliness, bullying victimisation, having been in a physical fight in the past 12 months, lack of parental or guardian support, tobacco use and having a history of ever got drunk were associated with suicidal ideation. Different rates of suicidal ideation were observed in ASEAN member states. Several risk factors for suicidal ideation were identified which can help guide preventive efforts.

This paper reports on a survey that was aimed at obtaining information for use in designing programs to reduce the incidence of adolescent pregnancy in Liberia. The sample of 1,488 never-married adolescents aged 14-21 was divided into subgroups based on age, sex, student status, and (for non-students) level of education. Although 57-93 percent of respondents claimed to have received information on reproductive health, only 2-21 percent could identify the monthly fertile period. Thirty to 49 percent of females ages 14-17 years have sexual relations at least once a month; over 80 percent of female non-students ages 18-21 years are sexually active. Highest levels of current contraceptive use were reported for 18-21-year-old female students (51 percent). Never-use of contraception among sexually active respondents was 97 percent for 14-17-year-old non-student females with a low educational level. Insufficient information about family planning methods and inaccessibility were the main reasons cited for non-use. Half of females ages 14-21 years who are currently attending school have been pregnant, as have 67 percent of those not in school. These results indicate a substantial unmet need on the part of Liberian adolescents with respect to reproductive health knowledge, information, and access to contraceptive methods.

To define age at entry into Tanner stages in children with perinatal HIV-1 infection. Multicentre longitudinal study including 212 perinatally HIV-1-infected children (107 girls and 105 boys) followed-up during puberty (from 8 and 9 years onwards in girls and boys, respectively). Healthy children (843 girls and 821 boys) provided reference percentiles. P2 or B2 stages in girls and P2 or G2 stages in boys defined onset of puberty. The cumulative probability [95% confidence limit (CI)] of entry into each stage at different ages was estimated by the Kaplan-Meier product-limit method; differences were evaluated by log rank test. Relationships were tested using the Spearman's rank correlation coefficient. Ages of girls [years (95%CI)] at P2 [12.9 (12.6-13.2)], P3 [13.4 (13.0-13.8)], P4 [14.6 (14.0-15.2)], B2 [12.7 (12.2-13.2)], B3 [13.3 (12.8-14.0)] and B4 [14.6 (14.0-15.2)] stages were > 97th percentile (> or = 21 month delay) of controls. Ages of boys [years (95%CI)] at P2 [12.6 (12.1-13.1)], P3 [13.9 (13.4-14.4)], P4 [14.9 (14.2-15.6)], G2 [12.1 (11.5-12.7)], G3 [13.6 (13.1-14.1)] and G4 [14.9 (14.1-15.7)] stages were at the 75-97th percentiles (< or = 15 month delay). Age at onset of puberty was not related to clinical and immunological condition, antiretroviral treatment, weigh for height and age at onset of severe disease or immune suppression. Perinatal HIV-1 infection interferes with sexual maturation. The mechanisms by which this occurs should be elucidated and intervention strategies designed. Intervention could save much psychological distress, since associated linear growth failure can exacerbate adolescents' feelings of being different and unwell.

Purpose To determine the prevalence of refractive errors among high school students. Methods In a cross-sectional study, we applied stratified cluster sampling on high school students of Aligoudarz, Western Iran. Examinations included visual acuity, non-cycloplegic refraction by autorefraction and fine tuning with retinoscopy. Myopia and hyperopia were defined as spherical equivalent of -0.5/+0.5 diopter (D) or worse, respectively; astigmatism was defined as cylindrical error >0.5 D and anisometropia as an interocular difference in spherical equivalent exceeding 1 D. Results Of 451 selected students, 438 participated in the study (response rate, 97.0%). Data from 434 subjects with mean age of 16±1.3 (range, 14 to 21) years including 212 (48.8%) male subjects was analyzed. The prevalence of myopia, hyperopia and astigmatism was 29.3% [95% confidence interval (CI), 25-33.6%], 21.7% (95%CI, 17.8-25.5%), and 20.7% (95%CI, 16.9-24.6%), respectively. The prevalence of myopia increased significantly with age [odds ratio (OR)=1.30, P=0.003] and was higher among boys (OR=3.10, P<0.001). The prevalence of hyperopia was significantly higher in girls (OR=0.49, P=0.003). The prevalence of astigmatism was 25.9% in boys and 15.8% in girls (OR=2.13, P=0.002). The overall prevalence of high myopia and high hyperopia were 0.5% and 1.2%, respectively. The prevalence of with-the-rule, against-the-rule, and oblique astigmatism was 14.5%, 4.8% and 1.4%, respectively. Overall, 4.6% (95%CI, 2.6-6.6%) of subjects were anisometropic. Conclusion More than half of high school students in Aligoudarz had at least one type of refractive error. Compared to similar studies, the prevalence of refractive errors was high in this age group.

To determine the prevalence of visual impairment attributable to refractive error and other causes in a youthful Ghanaian population. A prospective survey of all consecutive visits by first-year tertiary students to the Optometry clinic between August, 2013 and April, 2014. Of the 4378 first-year students aged 16-39 years enumerated, 3437 (78.5%) underwent the eye examination. The examination protocol included presenting visual acuity (PVA), ocular motility, and slit-lamp examination of the external eye, anterior segment and media, and non-dilated fundus examination. Pinhole acuity and fundus examination were performed when the PVA≤6/12 in one or both eyes to determine the principal cause of the vision loss. The mean age of participants was 21.86 years (95% CI: 21.72-21.99). The prevalence of bilateral visual impairment (BVI; PVA in the better eye ≤6/12) and unilateral visual impairment UVI; PVA in the worse eye ≤6/12) were 3.08% (95% CI: 2.56-3.72) and 0.79% (95% CI: 0.54-1.14), respectively. Among 106 participants with BVI, refractive error (96.2%) and corneal opacity (3.8%) were the causes. Of the 27 participants with UVI, refractive error (44.4%), maculopathy (18.5%) and retinal disease (14.8%) were the major causes. There was unequal distribution of BVI in the different age groups, with those above 20 years having a lesser burden. Eye screening and provision of affordable spectacle correction to the youth could be timely to eliminate visual impairment. Copyright © 2014 Spanish General Council of Optometry.

There have been few reports on Helicobacter pylori (H. pylori) infection in asymptomatic Japanese children and adolescents. We hypothesized that the prevalence of H. pylori infection is very low among Japanese children and that clinical variables such as serum pepsinogen and iron levels are associated with H. pylori infection. We conducted a cross-sectional analysis of a sample of 454 junior high school students aged 12-15 years in four areas in Nagano Prefecture. A commercial ELISA kit (E-plate Eiken H. pylori antibody) was used to measure IgG antibody against H. pylori. Serum pepsinogen and iron levels were also measured using standard methods. A urea breath test was performed for seropositive students. The overall prevalence of H. pylori was 3.1% (14/454). There were no significant differences in H. pylori prevalence among mountain, rural, and urban areas. The mean level of both serum pepsinogen (PG I) and PG II was significantly increased in the seropositive subjects compared with the seronegative subjects. When the cutoff values for adults (PG I: 70 ng/mL and PG I/II ratio: 3) were used, 4 of 14 subjects had PG I ≤70 ng/mL and PG I/II ratio ≤3. The results of a logistic regression analysis showed that low serum iron levels were significantly associated with H. pylori infection (P=.02). The prevalence of H. pylori infection is as low as 3% among junior high school students aged 12-15 years in Japan. The disappearance of H. pylori is accelerating in Japanese children. © 2016 John Wiley & Sons Ltd.

This study aims to broaden the current body of knowledge regarding the sexual behaviour of young Australians by examining the age and correlates of age of first intercourse in a national sample of Technical and Further Education apprentices. In 1995, students at randomly selected technical colleges in Australia were surveyed on HIV-related issues. Questionnaires were administered to a stratified cluster sample of automotive, hairdressing and commercial cookery apprentices. Respondents were asked the age at which they first had heterosexual vaginal or anal intercourse. Of 4,055 respondents aged 15-24 years, 3,848 answered the question; 3,195 (83%) had had intercourse. Males and females did not differ significantly. Median age at first intercourse was 16 (range 12-23). In multivariate analysis, older age at first intercourse was associated with: greater age at interview; higher school education; church attendance; and State of residence. The model, however, accounted for only 14% of the variance in age at first intercourse. In this sample, those apprentices who completed secondary school became sexually active later on average than those who left before the end of Year 10. For sex education to occur before sexual initiation, it needs to be offered in primary schools and the first year of high school (aged 11-13 years). Further, as technical college students are likely to initiate sex earlier than their age mates still at school, colleges may be in a position to take responsibility for the continuing sexual education of this group, especially for those students entering college at 15 or 16 years of age.

The purpose of the present study was to explore what parents know about their Children's boredom in school; specifically, the frequency, intensity, and antecedents of their Children's boredom, as well as how they cope with boredom. A questionnaire was administered to 437 grade 9 students (54% female, M age = 14.82) and their parents (72% mothers, 14% fathers, 12% both parents, M age = 45.26) measuring variables related to students boredom in mathematics class. Three different measurements were used to evaluate the accuracy of parents' judgments: (1) the correlation between parents' and students' answers, (2) the mean differences between parents' and students' answers, and (3) the mean values of absolute differences of parents' and students' answers. The results suggest that parents generally have an informed knowledge about their child's boredom and related facets. This is reflected by a mean correlation of medium size ( = 0.34) and a small mean effect size of the difference between parents' and students' judgments over all items ( = 0.20). Parents are also substantially better in judging their Children's boredom compared to guessing for all variables (mean effect size of = 0.65). They had the most precise judgments for the frequency and intensity of boredom. The antecedents of boredom (e.g., characteristics of instruction) were also well estimated by parents; specifically, parents tend to have a bias in favor for their children evidenced by overestimating antecedents that cannot be influenced by the students and underestimating those that can be influenced by the students. The least concordance was found between parents' and Children's perception of boredom coping strategies (e.g., accepting boredom), implying that parents lack information about how their children intentionally cope with boredom. Implications for research on student boredom are discussed as well as practical applications involving parents in boredom prevention.

We investigated the sleep problems and sleep habits of adolescents at three public primary schools and two high schools. Our study included 428 Turkish school children (244 girls and 184 boys). We used a questionnaire to determine the time they went to sleep at night; waking time in the morning; incidence of nightmares, snoring, daytime sleepiness, and intrafamilial physical trauma; concentration difficulty in class; and school success. The students were divided into age-related groups (group 1 = 11 to 13 years of age; group 2 = 14 to 15 years; group 3 = 16 to 18 years). The time they went to sleep was mostly between 10 and 11 p.m. in groups 1 and 2, and 11 to 12 p.m. in group 3. Difficulty in falling asleep was reported by 16.8 to 19.6% of the students in the three groups. Difficulty in waking up in the morning was reported by 12.7% of group 1, 16.0% of group 2, and 16.8% of group 3. Snoring was present in 12.1% of females and 22.0% of males. The occurrence of one nightmare in the preceding 3 months was reported by 11.3% of the students; 17.9% of the students reported having nightmares several times. Daytime sleepiness was present in 65.1%, and concentration difficulty was present in 56.8% of the students. We conclude that difficulty in falling asleep, snoring, and daytime sleepiness may be seen in adolescents who are in both primary and high schools. Watching inappropriate programs and movies on television and intrafamilial physical trauma may cause nightmares and sleeping problems in these adolescents. Students and families should be educated about the importance of sleep in academic performance. Countries' public health policies should address sleep problems and related educational activities.

Left-side LL and ST (n = 35 each) were obtained from U.S. Select carcasses classified at the grading stand by the U.S. Meat Animal Research Center visible and near-infrared spectroscopy tenderness system to have predicted slice shear force greater than 16.5 kg at 14 d postmortem. At 2 d postmortem, 2.54 cm thick steaks were cut from each muscle and assigned to 1 of the following treatments: 2 d fresh (2FRESH), 2 d freeze + thaw (2FREEZE), 2 d freeze + thaw + 12 d age (2FREEZE+12AGE), 14 d fresh (14FRESH), 14 d freeze + thaw (14FREEZE), 14 d freeze + thaw + 14 d age (14FREEZE+14AGE), and 28 d fresh (28FRESH). Steaks assigned to a freezing treatment were frozen at -26°C for 30 d before thawing/cooking or thawing with an additional aging period at 2°C. Slice shear force for LL and ST was lower (P < 0.01) for 2FREEZE (27.4 and 24.5 kg) and 14FREEZE (22.4 and 22.4 kg) compared to 2FRESH (33.0 and 29.2 kg) and 14FRESH (25.3 and 25.5 kg), respectively. Slice shear force for LL and ST was lower (P < 0.01) for 2FREEZE+12AGE (17.8 and 20.8 kg) and 14FREEZE+14AGE (14.6 and 19.0 kg) compared to 14FRESH (25.3 and 25.5 kg) and 28FRESH (18.7 and 21.7 kg), respectively. Desmin degradation for LL was not different (P > 0.05) between 2FREEZE (21.0%) and 2FRESH (14.6%) or between 14FREEZE (40.4%) and 14FRESH (38.4%); however, desmin degradation was higher (P < 0.06) in 2FREEZE+12AGE (46.7%) and 14FREEZE+14AGE (71.1%) when compared to 14FRESH (38.4%) and 28FRESH (60.5%), respectively. Cooking loss for LL was higher (P < 0.01) in 2FREEZE+12AGE (15.2%) compared to 14FRESH (14.0%) but was not different (P > 0.05) between 14FREEZE+14AGE (15.0%) and 28FRESH (14.3%). Freezing and thawing or a combination of freezing, thawing, and aging resulted in increased tenderness for LL and ST steaks when compared to fresh steaks with the same aging time. These results indicate freezing could be incorporated into normal commercial product distribution processes to improve the consistency of meat tenderness. Researchers who freeze steaks before tenderness assessment should be aware and acknowledge that freezing affects tenderness data.

To estimate the prevalence of bullying from the perspective of victims in students from the Southeast region of Brazil and analyze its association with individual variables and family context. Information on 19,660 adolescents from the National School-based Health Survey was analyzed, calculating the association between bullying and sociodemographic variables, risk behaviors, mental health, and family background. Multivariate analysis and the calculation of odds ratio and confidence intervals were performed. The prevalence of bullying was 7.8% (95%CI 6.5 - 9.2). After adjustment, the following associations were observed: students with less than 13 years of age (OR = 2.40; 1.4 - 3.93); protection for those aged 14, 15, and 16 years; male gender (OR = 1.47; 95%CI 1.35 - 1.59); black color (OR = 1.24; 95%CI 1.11 - 1.40); yellow color (OR = 1.38 95%CI 1.14 - 1.6); private school students (OR = 1.11; 95%CI 1.01 - 1.23); and students who work (OR = 1.30; 95%CI 1.16 - 1.45). Higher education of the mothers was a protective factor in all groups. Risk factors considered were feeling lonely (OR = 2.68; 95%CI 2.45 - 2.94), having insomnia (OR = 1.95; 95%CI 1.76 - 2.17), having no friends (OR = 1.47; 95%CI 1.24 - 1.75), suffering physical abuse from family members (OR = 1.83; 95%CI 1.66 - 2.03), missing classes without their parents' knowledge (OR = 1.23; 95%CI 1.12 - 1.34), as well as family supervision (OR = 1.14; 95%CI 1.05 - 1.23). To have drunk in the last 30 days (OR = 0.88 95%CI 0.8 - 0.97) was a protective factor. Bullying increases vulnerabilities among students, which suggests the need for an intersectoral approach in order to find measures to prevent them.

To identify the causes of blindness in children attending a school for the blind in Hong Kong. Cross-sectional observational study. School for blind children in Hong Kong. Eighty-two blind students at the Ebenezer School and Home for the Visually Impaired were examined between December 1998 and August 1999. Demographic data were obtained from students and a questionnaire assessment made of their medical and ocular history. Visual acuity was assessed and visual loss classified according to the World Health Organization classification of visual impairment. Complete ophthalmic assessments were performed in all students including slit-lamp examination and dilated binocular indirect ophthalmoscopy. The mean age of the students was 12.2 years. Ten (12.2%) had a family history of eye disease. Major past medical illnesses were reported in 50% with prematurity and diseases of the central nervous system found in 26.8% and 11.0% of students, respectively. The most common anatomical site for visual impairment was the retina (47.6%), followed by diseases of the optic nerve (14.6%), and diseases of the anterior segment and the lens (14.6%). The pattern of childhood blindness in Hong Kong is similar to that seen in other developed countries. Preventable causes of childhood blindness, such as prematurity and birth asphyxia, were responsible for a large proportion of cases. Early diagnosis and treatment of such conditions may reduce the incidence of childhood blindness in Hong Kong.

The aims of the present study were to assess the prevalence of bullying victimization among Korean adolescents by sex and age and to investigate the correlates of this phenomenon. Of 3,200 eligible subjects, 2,936 (91.8%) adolescents were recruited from four elementary schools (6th grade, age range: 10-12 years), five middle schools (8th grade, age range: 13-14 years), and three high schools (10th grade, age range: 15-17 years) located in the Jeju Special Self-Governing Province, Republic of Korea. This study used a self-administered questionnaire to collect data on sociodemographic characteristics and experiences of bullying victimization and employed the Korean form of the Children's Depression Inventory to evaluate depressive symptoms. Of the total sample of 2,936 students, 1,689 were boys (57.5%) and 1,247 were girls (42.5%). The prevalence of bullying victimization by age group was as follows: 10-12 years, 9.5%; 13-14 years, 8.3%; and 15-17 years, 6.4%. A significant difference in the prevalence of bullying victimization was observed by sex (boys: 45.0%, girls: 55.0%). Overall, the prevalence decreased with age. After adjusting for age and sex, bullying victimization was significantly associated with lower socioeconomic status (odds ratio [OR] =1.67; 95% confidence interval [CI] 1.04-2.67), lower than average academic achievement (OR =1.77; 95% CI 1.25-2.50), more depressive symptoms (OR =1.88; 95% CI 1.38-2.55), and poorer perceived relationship with parents (OR =1.46; 95% CI 1.00-2.14). Our findings will provide researchers and public health practitioners with data on the prevalence of bullying victimization and help to identify the risk factors for later behavioral and emotional problems.

To assess the prevalence of phosphodiesterase 5 (PDE5) inhibitor use and associated factors among University of Gondar undergraduate students. An institution-based, cross-sectional study, using a survey questionnaire, was conducted from October to December 2015 to assess PDE5 inhibitor use and associated factors among male students at the University of Gondar. A Self-Esteem and Relationship questionnaire (14 items), an International Index of Erectile Function questionnaire (15 items) and a questionnaire on PDE5 inhibitor use (14 items) were included in the survey. Across all respondents (age, 21.9±1.88 years), more than half (55.7%, n=233) had heard about PDE5 inhibitors, but only 23 men (5.5%) reported trying a PDE5 inhibitor drug at least once. Older students were more likely to use PDE5 inhibitors compared to younger students (adjusted odds ratio [AOR], 1.40; 95% confidence interval [CI], 1.109~1.768). Those students who were smokers were 5.15 times more likely to use PDE5 inhibitors as compared to their non-smoking counterparts (AOR, 5.15; 95% CI, 2.096~12.687). In addition, multivariate logistic regression showed that being in a relationship, alcohol use, greater number of cigarettes smoked per day, and more sexual partners were significantly associated with PDE5 inhibitor use. The prevalence of PDE5 inhibitor use among undergraduate students was 5.5%. Cigarette smoking and other substance use, older age, and greater number of sexual partners were significantly associated factors for PDE5 inhibitor use. These findings suggest that restricting access to PDE5 inhibitor drugs is essential to curtailing misuse among university students.

Background: Substance abuse prevalence and the number of suicides among university students is less than public population; however the sensitivity of society regarding the occurrence of such damages among students puts special emphasis on appraising these variables. More than 30% of Iranian students study in Islamic Azad University. Objectives: The current research aimed to appraise the vulnerability of substance abuse and the risk of suicide in students of region 12 of Islamic Azad University. Patients and Methods: In the current study, 1053 students (606 boys and 447 girls) with the average age of 22.55 years were selected through stratified sampling from Karaj, Takestan, Qazvin and Qom branches of Islamic Azad University. In order to assess the variables, Mental Health Worksheet of Central Counseling Office of the Ministry Science, Research and Technology was utilized. Results: Average, standard deviation, minimum and maximum scores in substance abuse vulnerability of the students in region 12 were measured as 36.28, 14.68, 11.22 and 92.87; and the same for risk of suicide were 31.29, 15.61, 7.93 and 96.30, respectively. Students in Qom branch were significantly less vulnerable to substance abuse and less exposed to the risk of suicide than their peers in Karaj, Qazvin and Takestan branches. Conclusions: Less significant possibility of substance abuse and risk of suicide in students of Qom branch in comparison with other branches could be due to numerous variables particularly their religious attitudes. Nevertheless the average of these variables among the students of region 12 were higher than the reported scores of their peers in the state universities which reflects the serious need for precise assessments and providing preventive services and mental health interventions.

This study explored whether college students who were first intoxicated by alcohol at ages younger than 19 are more likely to become alcohol dependent and frequent heavy drinkers, drive after drinking, ride with intoxicated drivers and be injured after drinking. It also investigated whether these results occur because these students believe they can drink more and still drive legally and safely. In 1999, 14,138 of 23,751 full-time 4-year students from a random sample of 119 college and universities nationwide completed self-administered questionnaires (response rate: 60%). This analysis focused on 12,550 who were aged 19 or older. Respondents were asked the age at which they first got drunk, as well as questions about recent alcohol-related behaviors and consequences. Compared with respondents first drunk at age 19 or older, those first drunk prior to age 19 were significantly more likely to be alcohol dependent and frequent heavy drinkers, to report driving after any drinking, driving after five or more drinks, riding with a driver who was high or drunk and, after drinking, sustaining injuries that required medical attention. Respondents first intoxicated at younger ages believed they could consume more drinks and still drive safely and legally; this contributed to their greater likelihood of driving after drinking and riding with high or drunk drivers. Educational, clinical, environmental and legal interventions are needed to delay age of first intoxication and to correct misperceptions among adolescents first drunk at an early age about how much they can drink and still drive safely and legally.

We assessed the effect of internal possession (IP) laws, which allow law enforcement to charge underage drinkers with alcohol possession if they have ingested alcohol, on underage drinking behaviors. We examined Youth Risk Behavior Survey (YRBS) data from 12 states with IP laws and with YRBS data before and after each law's implementation. We used logistic regression models with fixed effects for state to assess the effects of IP laws on drinking and binge drinking among high school students. Implementation of IP laws is associated with reductions in the odds of past-month drinking. This reduction was bigger among male than among female adolescents (27% vs 15%) and only significant among younger students aged 14 and 15 years (15% and 11%, respectively). Male adolescents also reported a significant reduction (24%) in the odds of past-month binge drinking under IP laws. These findings suggest that IP laws are effective in reducing underage drinking, particularly among younger adolescents.

Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45 ± 1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (p<0.05) and negatively associated with BMI (p<0.001). Students from urban areas attained menarche earlier than those from rural areas (p<0.05). Students from small-sized families attained menarche earlier than those from larger families (p<0.05). First-born students experienced menarche earlier than those who were seventh-born or later. Obese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

The present inquiry set to assess the relationship between snack consumption and meal skipping in Iranian children and adolescents. Overall, 14,880 students, aged 6-18 years, were selected via multistage cluster sampling method from rural and urban areas of 30 provinces of Iran. A validated questionnaire of food behaviors including questions on snacks consumption and taking/skipping meals was completed. Consuming and skipping meals and their related factors were reported in both crude and adjusted models. Overall, 13,486 students with a mean age of 12.47 ± 3.36 years completed the study (90.6% participation rate). Among them, 32.08, 8.89, and 10.90% skipped breakfast, lunch, and dinner, respectively. Compared to their counterpart groups, the frequency of meal skipping was higher in girls, urban inhabitants, and students in higher school grades (P < 0.05). Snack consumption was associated with an increased odds ratio of meal skipping in many types of snack groups. Meal skipping and snack consumption were frequent among Iranian children and adolescents. Evidence based interventions are proposed to improve the students' eating habits.

Analyses concerning peer violence among girls and boys aged 13-17 years, in the context of socio- -economic characteristics of the family: family structure, parental employment status and perceived family wealth. Preliminary data from the recent HBSC studies conducted in 12 voivodeships in Poland in 2013 was used. The analyzes concerned 2300 students aged 13-17 years (45% boys) and focused on the following types of violence: being a perpetrator and a victim of bullying, participation in fights and cyberbullying. Chi-square test analysis and multivariate logistic regression models were used. Significantly more boys than girls experienced bullying (28% vs. 22%) and was perpetrators of violence in the school (39% vs. 25%). The youth from single-parent families significantly more often than students from two-parent families, participated in fights and was the perpetrators of violence in the school. Being a perpetrator and a victim of violence concerned mostly students from poor families and boys, whose father was unemployed. The following risk factors was identified- among boys: low economic status of the family (victims of bullying) and single-parent family (victims of cyberbullying), father's unemployment (the perpetrator of bullying) and age 13-14 years (victims and perpetrators of bullying, participation in fights) and among girls: low economic status of the family (cyberbullying), mother's unemployment and age 13-14 years (victims of violence). The family socio-economic factors, gender and age determine the type and the prevalence of peer violence. Low economic status of the family and single-parent family increases the risk of experiencing violence. For the prevention of bullying the educational role of the father and his commitment to family budget are important.

Objective The purpose of this study was to document the prevalence and describe the characteristics of alcohol-related sexual assault among middle and high school students. Method A Web-based, self-administered survey was used to collect data on 7th- through 12th-grade students (n = 1,037) in a large metropolitan area in the Midwest. A modified version of the Sexual Experiences Survey was used to ask students about their sexual victimization experiences so as to examine the involvement of alcohol within specific assault events. The sample was equally distributed by biological gender and ethnicity (white vs black) and was, on average (SD), 14 (2) years of age. Results Findings from the study indicate that alcohol was involved in approximately 12%–20% of the assault cases, depending on age and gender of the respondent. For females, the presence of alcohol during assault differed significantly based on the location at which the assault occurred, ranging from 6% (at the survivor’s home) to 29% (at parties or someone else’s home). Furthermore, alcohol-related assault among females was more likely to involve physical force than non-alcohol-related assault. Conclusions Results are discussed in light of the risk factors of alcohol-related assault among adolescents as well as the nature of social contexts that fosters alcohol-related sexual assault among both adolescents and college students.

To identify the prevalence of smoking and the presence of variables associated with the habit in children and adolescents of both sexes, aged 7 to 17 years, resident in the city of Maceió. A cross-sectional epidemiological study of the student population of the both private and public education systems at elementary and high school level. Sample size was calculated based on the minimum predicted prevalence of a large number of variables, including smoking itself. Cluster sampling was employed. A questionnaire on smoking habits was completed during individual interviews with each student. Children who admitted having smoked on 1 or more day during the previous 30 were defined as current smokers. The variables analyzed were related to: the students (age, sex, previous experimentation with cigarettes and paid employment), their educational status (public/private school, daytime/evening lessons, grade and repeated years) and their families (economic status, smoking parents and separated parents). A total of 1,253 students were analyzed (547 were male, mean age was 12.4+/-2.9 years). Observed smoking prevalence was 2.4%. Multivariate statistical analysis demonstrated significant associations between smoking and: increased age (odds ratio: 1.31); previous experimentation with cigarettes (odds ratio: 33.96); studying during the evening (odds ratio: 5.43). It was observed that 286 students (22.8%) admitted having experimented with cigarettes (9% from 7 to 9 years; 21% from 10 to 14 years; 36% from 15 to 17 years). The prevalence of smoking among children and adolescents in the Maceió educational system is 2.4%, being most common among students aged 15 to 17 years, studying in the evening. Students who had experimented with cigarettes exhibited a 34 times greater chance of becoming smokers.

Sexual intercourse among Malaysian adolescents is a major concern, especially with the worry of HIV/AIDS. This study was done to determine the prevalence of sexual intercourse among secondary school students aged 12 to 19 years in Negeri Sembilan, Malaysia. This is a cross-sectional school survey conducted on 4,500 adolescent students based on a structured questionnaire. Data were collected using the self-administered questionnaire (translated version of the Youth Risk Behaviour Surveillance in Bahasa Malaysia). The study showed that 5.4 percent of the total sample were reported to have had sexual intercourse. The proportion among male students who had had sex was higher (8.3 percent) compared with female students (2.9 percent). The mean age at first sexual intercourse was 15 years. One percent of students reported that they had been pregnant or had made someone else pregnant. Adolescent sexual intercourse was significantly associated with (1) socio-demographical factors (age, gender); (2) environmental factors (staying with parents); and (3) substance use (alcohol use, cigarette smoking, drug use), even after adjustment for demographical factors. The survey showed that 20.8 percent of respondents had taken alcohol, 14.0 percent had smoked cigarettes, 2.5 percent had tried marijuana, 1.2 percent had tried ecstasy pills, 2.6 percent had tried glue sniffing, 0.7 percent had tried heroin, and 0.7 percent had intravenous drugs. Prevalence of sexual intercourse among Malaysian adolescents was relatively low compared to developed countries. However, certain groups of adolescents tend to be at higher risk of engaging in sexual intercourse. This problem should be addressed early by targeting these groups of high-risk adolescents.

This cross-sectional study aimed to assess dental health and odontogenic infections in students with special health care needs (SHCN) in the Free State of Thuringia, Germany. From 1283 students with SHCN aged 6-16 years, 66.0 % (n = 848 of whom are 35.7 % females and 64.3 % males) with intellectual/learning disabilities (ID/LD), physical disabilities (PD), and sensory disorders (SD) participated after informed consent in oral examinations according to WHO standards. Dental caries was assessed by dmft/DMFT, odontogenic infections by pufa/PUFA. Fissure sealants (FS) were scored in permanent molars. Data were compared to regional and national reference data and analysed by t test and age-adjusted logistic regression models. Students with SHCN revealed 41.2 % caries prevalence in permanent and 31.7 % in primary teeth. Highest prevalence/experience of caries and odontogenic infections in primary teeth was recorded in 6-11-year-olds with PD (65.1 %/2.3 dmft; 14.0 %/0.3 pufa). Most affected permanent teeth were observed in students with ID/LD (12-16-year-olds 59.6 %/2.4 DMFT; 6-11-year-olds 2.8 %/0.03 PUFA). All odontogenic infections in 12-16-year-olds occurred in males; n = 9 students revealed n = 9 teeth with pufa/PUFA. Students with ID/LD aged 6-11 years exhibited lowest prevalence of FS (29.0 %) and mean of 0.8 FS. Students with SHCN suffered more than twice as frequent from untreated dental caries and benefited up to 29.0 % less from FS than peers without disabilities. This first study investigating odontogenic infections of German students with SHCN revealed highest prevalence in primary teeth and in males. Oral health among students with SHCN is reduced, and FS are underutilized compared to German students without disabilities. Reinforcing the application of FS in students with SHCN might contribute to reducing disparities in oral health.

Al-Mathkoori, Radhia; Nur, Ula; Al-Taiar, Abdullah

2017-06-17

Background There is strong evidence that the mean age of menarche has declined over the last few decades in developed and developing countries. This is of a major concern because of its enormous public health implications. This study aimed to estimate the age of menarche in Kuwait and investigate the association between menarcheal age and academic performance among high school girls in Kuwait. Methods A cross-sectional study was conducted on randomly selected female high school students from private and public high schools in all governorates in Kuwait. Data on the age of menarche were collected by self-administered questionnaire from the students, while data on academic performance were extracted from the students' academic records. Results Of the 907 students we selected, 800 (88.2%) responded. The mean age of menarche was 12.33 [95% confidence interval (CI) 12.18-12.49] years. There was no evidence for significant association between age of menarche and students' academic performance before or after adjusting for potential confounders. Conclusion The calculated age of menarche among contemporary girls in Kuwait is similar to that of the girls in industrialized countries. Early menarcheal age is unlikely to lead to adverse behavior that may affect academic performance in our setting.

Education policies encourage inclusion of students with mild-intellectual disability (mild-ID) in community/school life. However, such policies potentially increase exposure to substance use. This article examines tobacco, alcohol and cannabis use among French students enrolled in special units for students with disabilities (ULIS) at mainstream junior high schools compared to those of general population of the equivalent age; and explores factors associated with substance use among ULIS students, known to present mostly mild-ID. In 2014, a questionnaire adapted from the international HBSC/WHO study was administered to 700 ULIS students (mean-age 14.2). Comparative data were gathered from 7023 junior high-school students (mean-age 13.6) in the general population. Among students <14 years-old, tobacco and alcohol use rates were similar between ULIS and general population. For students ≥14, alcohol use remained comparable, while tobacco and cannabis use were higher in general population. Among ULIS students, low perceived health/life satisfaction, divorced/separated parents and high perceived academic demands were associated with tobacco use. Bullying, not liking school very much and attending schools outside a deprived area were associated with alcohol use. Having had sexual intercourse and not perceiving one's health as excellent were associated with cannabis use. Having dated was associated with using all three substances.

This study examined the knowledge and practices of adolescent school girls in Kano, Nigeria around menstruation and menstrual hygiene. Data was collected quantitatively and analyzed using Epi info version 3.2.05. The mean age of the students was 14.4 +/- 1.2 years; majority was in their mid adolescence. The students attained menarche at 12.9 +/- 0.8 years. Majority had fair knowledge of menstruation, although deficient in specific knowledge areas. Most of them used sanitary pads as absorbent during their last menses; changed menstrual dressings about 1-5 times per day; and three-quarter increased the frequency of bathing. Institutionalizing sexuality education in Nigerian schools; developing and disseminating sensitive adolescent reproductive health massages targeted at both parents and their adolescent children; and improving access of the adolescents to youth friendly services are veritable means of meeting the adolescent reproductive health needs in Nigeria.

Suicide is a potentially preventable public health issue. It is therefore important to examine its immediate precursors, including suicidal ideation and attempts, to help in the development of future public health interventions. The present study reports the prevalence of suicidal ideation and attempts in the past 12 months in children and adolescents and identifies correlates of such behaviors in a large and diverse sample of middle and high school students. Data were drawn from a representative sample of Ottawa students (n=1922) aged 11-20 years (14.4±1.9 years) from three cycles (2009, 2011 and 2013) of the Ontario Student Drug Use and Health Survey (OSDUHS), a cross-sectional school-based appraisal of students in grades 7-12 across Ontario, Canada. Overall, 10.8% of students exhibited suicidal ideation and 3.0% reported suicide attempts in the past 12 months. The conditional probability of making an attempt was 25.5% among suicide ideators. Multivariable analyses indicated that being a girl and using alcohol and cannabis were positively associated with suicidal ideation, while tobacco was positively associated with suicide attempts. Being a victim of school bullying was significantly associated with reports of suicidal ideation and attempts, whereas school connectedness had protective effects against both suicidal ideation and attempts. These results indicate that suicidal ideation and attempts are related to other risky behaviors. Suicide-prevention efforts should be integrated within broader health-promoting initiatives.

Homophobic Bullying and Cyberbullying: Study of a Silenced Problem.

2018-01-01

Bullying and cyberbullying have been studied extensively. In lesbian, gay, bisexual, and questioning (LGBQ) students, these phenomena seem to be overrepresented so that, although they share some common elements, homophobic bullying and cyberbullying could be considered as specific phenomena. This study analyzed homophobic bullying and cyberbullying, with the participation of 533 Spanish secondary school students aged from 12 to 20 (M = 14.9, SD = 1.7). The results showed that students identified as non-heterosexual experienced a higher level of being targeted with bullying and cyberbullying, almost one half of them declaring that they had been victimized and more than 20% cybervictimized. Many stated they had suffered both kinds of harassment. In addition, the prevalence of all kinds of bullying was higher among non-heterosexual students. Regression analyses showed that sexual orientation could be considered a risk factor for suffering these aggressions. We discuss results in relation to previous research and look at their practical implications.

The degree of overweight-obesity varies according to the conditions of each population and depending on geographical area, race or ethnicity, socioeconomic status, and susceptibility of each individual. The aim of this study was to determine anthropometric measures in urban child population from 6 to 12 years of Ciudad Obregón, Sonora. We studied 684 schoolchildren from 6 to 12 years of age, of both genders in the urban area of Ciudad Obregón, Sonora. We measured weight, height, arm circumference (AC), waist, and body mass index (BMI). We used descriptive statistics (frequencies, percentages), and to compare the growth charts of this study vs. the reference standards (CDC and Ramos-Galván), we employed statistical inference (Student t test). On average, weight, height, AC, BMI for age by gender were higher than the reference standards at all ages. Seventy-four boys (22 %) and 51 girls (14.5 %) were above 95th percentile. With regards to size, 42 children (12.6 %) were below the 5th percentile and 37 (10.5 %) above the 95th percentile. Schoolchildren in the southern zone of Sonora showed a higher anthropometric pattern than the reference standards.

To evaluate the use of telehealth to teach reproductive health to rural areas with high rates of teen pregnancy. Prospective cohort study. Two high schools in rural West Virginia. High school female students who attended telehealth sessions. Teleconferencing equipment connected rural high schools to a distal academic institution. Telehealth sessions included reproductive health and life skills topics. Demographic information, session pre- and post-tests, and 6- month assessment was obtained. Reproductive health knowledge, behavior, and self-efficacy were assessed at intervention and at 6 months, along with Likert scale evaluation of telehealth as an educational tool. Fifty-five students participated in the program with an average age of 16.14 (SD 1.24) years. Only 20% (10/50) of subjects' mothers and 12% (6/50) of subjects' fathers had achieved education beyond high school, and 20% (10/50) of subject's mothers had experienced teen pregnancies (age 18 or younger). Sexual activity was reported among 52% (26/50) of subjects, 4/50 (8%) reported desire to become pregnant within the next year, and 4/50 (8%) reported already pregnant. Thirty-seven students completed the 6-month follow-up survey. Reported condom use increased from 20% (10/50) at baseline to 40% (15/37) at 6 months (P = .04) and hormonal contraception use increased from 22% (11/50) to 38% (14/37) (P = .12). Report of human papillomavirus vaccination increased from 38% (10/26) to 70% (26/37) (P = .001) among all subjects. At 6 months, 91.8% (34/37) reported the use of telehealth was "very effective" as a means to teach the material. Telehealth is an effective tool to teach reproductive health to rural areas.

Cigarette smoking is a major preventable cause of morbidity and mortality worldwide. Most adult smokers start smoking regularly some time before 18 years of age. The aim of this study was to determine the age at which children begin cigarette smoking, to study the environmental factors that influence children to smoke, and to understand the reasons why children smoke. The results of this study may help lead to the development of more effective smoking prevention programs. We carried out a cross-sectional survey of all students in grades 6 to 11 (ages: 11 to 17 years) in two high schools in the Jerusalem area, using an anonymous self-completion questionnaire. The students were asked questions regarding the age at which they began smoking, initiation, their smoking habits, their reasons for smoking, and their views on children who smoke. In addition, they were asked about the smoking status of their parents, siblings, and friends. Finally they were asked about the health hazards of smoking. Of the 847 students who answered the questionnaire, 35% stated that they had smoked at least once and 14% stated that they were currently smoking. The percentage of students who were currently smoking increased gradually with age to 36%. There was a sharp increase in experimental smoking after seventh grade (ages 12 to 13 years). Having a friend who smoked substantially increased the likelihood of smoking, whereas parental smoking or having a sibling who smoked did not increase the likelihood of smoking. The most common reason for starting to smoke was "to try something new" (55%). There was a significant difference between the views of students with different smoking statuses regarding children who smoke: nonsmoking children associated more negative characteristics to smoking. All of the children studied were well aware of the health hazards of cigarette smoking. Smoking is highly prevalent among schoolchildren in Jerusalem. The increase in the rate of smoking at the age of 12 years indicates that smoking prevention programs need to be started at an earlier age. Peer pressure is a very strong stimulus for smoking in children. Since children are aware of the health hazards of smoking, prevention policy should be aimed more at associating smoking with negative images and addressing peer pressure.

Many countries desire more students to study science subjects, although relatively few students decide to study non-compulsory physics at upper-secondary school and at university. To gain insight into students' intentions to study non-compulsory physics, a longitudinal sample (covering 2258 students across 88 secondary schools in England) was surveyed in year 8 (age 12/13) and again in year 10 (age 14/15). Predictive modelling highlighted that perceived advice, perceived utility of physics, interest in physics, self-concept beliefs (students' subjective beliefs of their current abilities and performance) and home support specifically orientated to physics were key predictors of students' intentions. Latent-transition analysis via Markov models revealed clusters of students, given these factors at years 8 and 10. Students' intentions varied across the clusters, and at year 10 even varied when accounting for the students' underlying attitudes and beliefs, highlighting that considering clusters offered additional explanatory power and insight. Regardless of whether three-cluster, four-cluster, or five-cluster models were considered, the majority of students remained in the same cluster over time; for those who transitioned clusters, more students changed clusters reflecting an increase in attitudes than changed clusters reflecting a decrease. Students in the cluster with the most positive attitudes were most likely to remain within that cluster, while students in clusters with less positive attitudes were more likely to change clusters. Overall, the cluster profiles highlighted that students' attitudes and beliefs may be more closely related than previously assumed, but that changes in their attitudes and beliefs were indeed possible.

We investigated activity patterns of 17 elementary school students aged 10-12, and 19 high school students aged 13-17, in suburban Los Angeles during the oxidant pollution season. Individuals' relationships between ventilation rate (VR) and heart rate (HR) were calibrated' in supervised outdoor walking/jogging. Log VR was consistently proportional to HR; although calibrations' were limited by a restricted range of exercise, and possibly by artifact due to mouthpiece breathing, which may cause overestimation of VR at rest. Each subject then recorded activities in diaries, and recorded HR once per minute by wearing Heart Watches, over 3 days (Saturday-Monday). For each activitymore » the subject estimated a breathing rate--slow (slow walking), medium (fast walking), or fast (running). VR ranges for each breathing rate and activity type were estimated from HR recordings. High-school students' diaries showed their aggregate distribution of waking hours as 68% slow inside, 8% slow outside, 10% medium inside, 9% medium outside, 1.5% fast inside, 1.5% fast outside. Elementary students' distribution was 47% slow inside, 15% slow outside, 20% medium inside, 12% medium outside, 2.5% fast inside, 3.5% fast outside. Sleep occupied 38% of high-school students' and 40% of elementary students' time; HR were generally lower in sleep than in slow waking activity. High school students' mean VR estimates were 13 L/min for slow breathing, 18 for medium, and 23 for fast; elementary students' were 14 slow, 18 medium, and 19 fast. VR distributions were approximately lognormal. Maximum estimated VR were approximately 70 L/min in elementary and approximately 100 L/min in high school students. Compared to adults studied similarly, students reported more medium or fast breathing, and had equal or higher VR estimates during slow and medium breathing despite their smaller size. These results suggest that, relative to body size, young people inhale larger doses of outdoor air pollutants than adults.« less

Headache has been described as a factor with significant negative impact on the quality of life of school-aged children with a high risk of developing in chronic and persistent form in adulthood. Among other headache associated triggers or aggravating factors, lifestyle and obesity has been investigated, but results are still conflicting. To evaluate the prevalence of headache in school-aged children and its relationship to anthropometric characteristics, lifestyle, and quality of life. A cross-sectional study was conducted in six schools located in two cities in southern Brazil, involving 750 students aged 7 to 14 years. Information was collected on sociodemographic characteristics, clinical variables (presence of headache and menarche), anthropometric data, lifestyle, and quality of life. A total of 185 (24.7%) students reported having headache crises in the last 3 months. Among students aged 10 to 14 years, presence of headache was associated with female sex, affecting 32.2% of girls vs. 23.3% of boys (p = 0.042, chi-square test). Anthropometric parameters (data on overweight/obesity) were consistent with national prevalence rates, and there was no association between Body Mass Index (BMI) and headache. Regarding lifestyle, 2.0% of students reported smoking and 1.6% consuming alcohol occasionally, and neither was associated with headache. Quality of life, especially aspects of social life, appeared to be affected by the presence of headache. This study found a high prevalence of headache in school-aged children, which was associated with female students aged 10-14 years and quality of life. Copyright © AULA MEDICA EDICIONES 2013.

We investigated the frequency of alcohol ads at all 113 subway and streetcar stations in Boston and the patterns of community exposure stratified by race, socioeconomic status, and age. We assessed the extent of alcohol advertising at each station in May 2009. We measured gross impressions and gross rating points (GRPs) for the entire Greater Boston population and for Boston public school student commuters. We compared the frequency of alcohol advertising between neighborhoods with differing demographics. For the Greater Boston population, alcohol advertising at subway stations generated 109 GRPs on a typical day. For Boston public school students in grades 5 to 12, alcohol advertising at stations generated 134 GRPs. Advertising at stations in low-poverty neighborhoods generated 14.1 GRPs and at stations in high-poverty areas, 63.6 GRPs. Alcohol ads reach the equivalent of every adult in the Greater Boston region and the equivalent of every 5th- to 12th-grade public school student each day. More alcohol ads were displayed in stations in neighborhoods with high poverty rates than in stations in neighborhoods with low poverty rates.

To compare medical students' preference of smart phone television display (SPTD) to a slit-lamp teaching telescope (SLTT) in undergraduate clinical ophthalmology education. This is a randomized, crossover, comparative study. Pairs of medical students were randomly assigned to 2 teaching sessions using either SPTD first followed by SLTT or in reverse order. Students were asked to give feedback on the 2 teaching devices by answering 6 questions using a numeric rating score from 1 to 10. All participating students were sent the results of the study 1 month after the completion of the study and were asked to reflect upon the outcome. Thirty-eight students were recruited. The overall satisfaction scores were significantly higher for SPTD than SLTT (8.6 ± 1.4 vs 7.5 ± 1.0, p < 0.01). The students preferred SPTD compared with SLTT in terms of "visualization" (8.5 ± 1.4 vs 7.0 ± 1.3, p < 0.01), "ocular sign description" (8.4 ± 1.3 vs 7.2 ± 1.2, p < 0.01), "ocular anatomy understanding" (8.3 ± 1.2 vs 7.6 ± 1.2, p < 0.01), and "confidence in identifying clinical signs" (8.4 ± 1.2 vs 7.5 ± 1.2, p < 0.01). A larger proportion of the students gave higher scores to SPTD compared with SLTT in all questions. All students who responded to the follow-up questionnaire (n = 14) agreed with our interpretation of the data and would support the use of SPTD in undergraduate clinical ophthalmology teaching. Our study has demonstrated that the utility of SPTD as a teaching aid can significantly increase the satisfaction of undergraduate medical students during their ophthalmology attachment. It offers specific practical advantages in teaching medical students over the traditional SLTT. Copyright © 2017 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.

The objective of this study was to evaluate alcohol consumption patterns among vocational school students in central Thailand. We conducted a cross sectional study among 1,803 vocational students (80.4 % aged < 17 years) in central Thailand using a self-administered questionnaire which consisted of 2 parts: sociodemographic factors and alcohol drinking behavior from December 2007 to February 2008. Descriptive statistics, a chi-square test and multiple logistic regression were used to analyze the data. The results of this study showed 40.9% of male students and 20.9% of female students drank alcoholic beverages. Multiple logistic regression analysis revealed 2 factors were associated with alcohol consumption among male subjects: field of study (OR 1.5, 95% CI 1.1-2.0), and GPA (OR < 2 = 1.8; 95% CI 1.2-2.7; OR > 3 = 0.6; 95% CI 0.4-0.9). The three most popular venues for drinking were at parties (43.1%), at home/in the dormitory (34.9%) and in bars or saloons near the school (20.9%). Fifty-three point two percent of males drinks alcohol 1-2 times per month and time, 47% drank > 2 times per month. Nearly 78% of female students drink alcohol 1-2 times per month and 22% drink alcohol > 2 time per month. Forty point nine percent of male students consumed 1-2 drinks per time and 36% consumed more than 4 drinks per time. Fifty point four percent of females drank 2 drinks per month. One-third of male students said they engaged in binge drinking in a 2-week period and 14% of girls said they binge drank in a 2-week period. Alcohol consumption is a significant problem among Thai vocational school students. Measures for managing this problem are discussed.

Objectives The aims of the present study were to assess the prevalence of bullying victimization among Korean adolescents by sex and age and to investigate the correlates of this phenomenon. Methods Of 3,200 eligible subjects, 2,936 (91.8%) adolescents were recruited from four elementary schools (6th grade, age range: 10–12 years), five middle schools (8th grade, age range: 13–14 years), and three high schools (10th grade, age range: 15–17 years) located in the Jeju Special Self-Governing Province, Republic of Korea. This study used a self-administered questionnaire to collect data on sociodemographic characteristics and experiences of bullying victimization and employed the Korean form of the Children’s Depression Inventory to evaluate depressive symptoms. Results Of the total sample of 2,936 students, 1,689 were boys (57.5%) and 1,247 were girls (42.5%). The prevalence of bullying victimization by age group was as follows: 10–12 years, 9.5%; 13–14 years, 8.3%; and 15–17 years, 6.4%. A significant difference in the prevalence of bullying victimization was observed by sex (boys: 45.0%, girls: 55.0%). Overall, the prevalence decreased with age. After adjusting for age and sex, bullying victimization was significantly associated with lower socioeconomic status (odds ratio [OR] =1.67; 95% confidence interval [CI] 1.04–2.67), lower than average academic achievement (OR =1.77; 95% CI 1.25–2.50), more depressive symptoms (OR =1.88; 95% CI 1.38–2.55), and poorer perceived relationship with parents (OR =1.46; 95% CI 1.00–2.14). Conclusion Our findings will provide researchers and public health practitioners with data on the prevalence of bullying victimization and help to identify the risk factors for later behavioral and emotional problems.

There are very few studies in Spain that treat underachievement rigorously, and those that do are typically related to gifted students. The present study examined the proportion of underachieving students using the Rasch measurement model. A sample of 643 first-year high school students (mean age = 12.09; SD = 0.47) from 8 schools in the province of Alicante (Spain) completed the Battery of Differential and General Skills (Badyg), and these students' General Points Average (GPAs) were recovered by teachers. Dichotomous and Partial credit Rasch models were performed. After adjusting the measurement instruments, the individual underachievement index provided a total sample of 181 underachieving students, or 28.14% of the total sample across the ability levels. This study confirms that the Rasch measurement model can accurately estimate the construct validity of both the intelligence test and the academic grades for the calculation of underachieving students. Furthermore, the present study constitutes a pioneer framework for the estimation of the prevalence of underachievement in Spain. PMID:26973586

Rapidly increasing tobacco use in developing countries will result in a large and increasing burden of tobacco-related illnesses as their populations age. The Republic of the Marshall Islands (RMI) is an island nation in the Pacific with a 1999 census population of 50,840, of whom more than fifty percent were under twenty years of age. There are limited data on the prevalence of smoking among youth in the RMI. A school survey of 3,294 RMI students in grades 5 through 12 was conducted in 2000. Urban and outer atoll schools were included in the sample. Demographic data and information on tobacco use and risk factors were collected. The overall smoking rate in this school sample was 10.6%. There were significantly higher smoking rates in the high school age group; the rate of smoking among 18 year olds was 33.5%. Smoking rates were higher among males compared to females (18.7% vs. 3.4%) and higher among outer atoll students compared to urban students (14.5% vs. 9.4%). The most prominent risk factors for smoking were: age, male gender, receiving or wearing tobacco-labeled equipment or clothing and willingness to participate in other high-risk behaviors. The survey provides an estimate of smoking rates among Marshallese school students and identifies and quantifies significant risk factors for smoking. This information can assist in guiding a comprehensive tobacco control strategy in the Republic of the Marshall Islands.

Purpose: Since March 2007, the Standing Committee on Vaccination (STIKO) recommends HPV vaccination for all 12–17 y-old females in Germany. In the absence of an immunization register, we aimed at assessing HPV-vaccination coverage and knowledge among students in Berlin, the largest city in Germany, to identify factors influencing HPV-vaccine uptake. Results: Between September and December 2010, 442 students completed the questionnaire (mean age 15.1; range 14–19). In total 281/442 (63.6%) students specified HPV correctly as a sexually transmitted infection. Of 238 participating girls, 161 (67.6%) provided their vaccination records. Among these, 66 (41.0%) had received the recommended three HPV-vaccine doses. Reasons for being HPV-unvaccinated were reported by 65 girls: Dissuasion from parents (40.2%), dissuasion from their physician (18.5%), and concerns about side-effects (30.8%) (multiple choices possible). The odds of being vaccinated increased with age (Odds Ratio (OR) 2.19, 95% Confidence Interval (CI) 1.16, 4.15) and decreased with negative attitude toward vaccinations (OR = 0.33, 95%CI 0.13, 0.84). Methods: Self-administered questionnaires were distributed to 10th grade school students in 14 participating schools in Berlin to assess socio-demographic characteristics, knowledge, and statements on vaccinations. Vaccination records were reviewed. Multivariable statistical methods were applied to identify independent predictors for HPV-vaccine uptake among female participants. Conclusions: HPV-vaccine uptake was low among school girls in Berlin. Both, physicians and parents were influential regarding their HPV-vaccination decision even though personal perceptions played an important role as well. School programs could be beneficial to improve knowledge related to HPV and vaccines, and to offer low-barrier access to HPV vaccination. PMID:22995838

Although the relationships between economic conditions and biological variables over the past two centuries in Poland are reasonably well-documented, the influence of economic and political disruptions, including nutritional privation, during the years immediately before, during and shortly after World War II (WWII) has received less attention. This paper considers the association between age at menarche and body size of university students born before, during and after WWII and father's level of education, a commonly used indicator of family economic status in Poland. Subjects were 518 university students surveyed between 1955 and 1972, birth years 1931 through 1951. The sample was divided into three birth cohorts: before (n=237), during (n=247) and after (n=34) WWII. Age at menarche was compared among birth cohorts, and by weight status and father's level of education. Age at menarche increased slightly but significantly among women born during WWII (14.4 yrs) compared to those born before (14.2 yrs) and after (13.9 yrs) the war. Controlling for year of birth and age of the student, age at menarche was significantly earlier in overweight (13.42±0.35 yrs) than in normal weight (14.33±0.06 yrs) and thin (14.54±0.21 yrs) women. Adjusted mean ages at menarche in small samples of overweight women did not differ by father's level of education, and were earlier than corresponding ages of thin and normal weight women. Adjusted mean ages at menarche did not differ between thin and normal weight women with fathers having primary or no education, but were slightly later in thin than in normal weight women with fathers having a vocational, secondary or higher education. Although age at menarche was associated with father's level of education, young adult weight status was a somewhat more important correlate. Copyright © 2017 Elsevier B.V. All rights reserved.

2007-10-01

The first longitudinal investigation of the extent to which same-age and older schoolmates' smoking and non-smoking are associated with adolescents' smoking transitions during three grade intervals. Same-age and older schoolmates' smoking and non-smoking were assessed when adolescents were at grades 5 (age 10), 7 (age 12) and 9 (age 14). Adolescents' smoking transitions were assessed at three grade intervals: 5th-7th (age 10-12), 7th-9th (age 12-14) and 9th-12th (age 14-17). Forty Washington State school districts. Smoking questionnaire data were gathered on a cohort of adolescents (n = 4354 for same-age schoolmate analysis; n = 1833 for older schoolmate analysis) that was 49% female and 91% Caucasian. No significant evidence that same-age schoolmates' smoking or non-smoking was associated with any of the adolescent smoking transitions at any of the three grade intervals. In contrast, the probability that each older schoolmate's smoking was associated with the adolescent making the transition to trying smoking was 1% (95% CI: 0.4%, 1.5%) and with the transition from trying to monthly smoking was also 1% (95% CI: 0.2%, 2.0%) during the 7th-9th grade (age 12-14) interval. Moreover, each older schoolmate's non-smoking was associated with a 1.001-1.006 (all P < 0.05) relative risk of an adolescent not trying smoking or escalating from trying to monthly smoking at several grade intervals. Interventions should perhaps focus on the influence of both smoking and non-smoking older schoolmates during late childhood and early adolescence.

Low physical activity and sedentary behaviors, two important determinants of childhood obesity, may be influenced by parental lifestyle and weight status. This study aims to determine the association of parental weight status with children's physical activity and screen time. This study was conducted on 14,440 Iranian schools students, aged 7-18 years, and one of their parents, who participated in the large national school-based surveillance program. The children's screen-based and physical activities were evaluated based on the World Health Organization's Global School Student Health Survey. Children and parental height, weight, and waist circumference were measured using standardized methods. Overall, 14,274 students and one of their parents completed the survey (participation rate: 99%). Mean (standard deviation) age of students was 12.3 (3.2) years, and the prevalence of low physical activity and high screen time was 58.2% and 17.7%, respectively. In multivariate model, the parental general obesity and abdominal obesity increased the odds of children having low physical activity, by 21% and 13%, respectively. Parental overweight, general obesity, and abdominal obesity increased the odds of the combination of low physical activity/high screen time in children by 33%, 26%, and 20%, respectively. This study showed that parental obesity was associated with increased screen-based activities and low physical activity in children. Focus on parental weight status, as an important factor influenced by their lifestyle, can be helpful for preventing sedentary behaviors in their children.

Resilience is a capacity to face and overcome adversities, with personal transformation and growth. In medical education, it is critical to understand the determinants of a positive, developmental reaction in the face of stressful, emotionally demanding situations. We studied the association among resilience, quality of life (QoL) and educational environment perceptions in medical students. We evaluated data from a random sample of 1,350 medical students from 22 Brazilian medical schools. Information from participants included the Wagnild and Young's resilience scale (RS-14), the Dundee Ready Educational Environment Measure (DREEM), the World Health Organization Quality of Life questionnaire - short form (WHOQOL-BREF), the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). Full multiple linear regression models were adjusted for sex, age, year of medical course, presence of a BDI score ≥ 14 and STAI state or anxiety scores ≥ 50. Compared to those with very high resilience levels, individuals with very low resilience had worse QoL, measured by overall (β=-0.89; 95% confidence interval =-1.21 to -0.56) and medical-school related (β=-0.85; 95%CI=-1.25 to -0.45) QoL scores, environment (β=-6.48; 95%CI=-10.01 to -2.95), psychological (β=-22.89; 95%CI=-25.70 to -20.07), social relationships (β=-14.28; 95%CI=-19.07 to -9.49), and physical health (β=-10.74; 95%CI=-14.07 to -7.42) WHOQOL-BREF domain scores. They also had a worse educational environment perception, measured by global DREEM score (β=-31.42; 95%CI=-37.86 to -24.98), learning (β=-7.32; 95%CI=-9.23 to -5.41), teachers (β=-5.37; 95%CI=-7.16 to -3.58), academic self-perception (β=-7.33; 95%CI=-8.53 to -6.12), atmosphere (β=-8.29; 95%CI=-10.13 to -6.44) and social self-perception (β=-3.12; 95%CI=-4.11 to -2.12) DREEM domain scores. We also observed a dose-response pattern across resilience level groups for most measurements. Medical students with higher resilience levels had a better quality of life and a better perception of educational environment. Developing resilience may become an important strategy to minimize emotional distress and enhance medical training.

Risk versus direct protective factors and youth violence: Seattle social development project.

2012-08-01

Numerous studies have examined predictors of youth violence associated with the individual child, the family, school, and the surrounding neighborhood or community. However, few studies have examined predictors using a systematic approach to differentiate and compare risk and direct protective factors. This study examines risk and protective factors associated with youth violence in an ongoing longitudinal panel study of 808 students from 18 Seattle public elementary schools followed since 1985 when they were in 5th grade. Predictors span the individual, family, school, peer, and neighborhood domains. Data were collected annually, beginning in 1985, to age 16 years, and then again at age 18 years. This paper provides findings of analyses in which continuous predictor variables, measured at ages 10-12 years, were trichotomized to reflect a risk end of the variable, a direct protective end, and a middle category of scores. Youth violence was measured at ages 13-14 years and 15-18 years. Bivariate analyses of risk and direct protective factors identified the following predictors of violence at ages 13-14 years and 15-18 years. Risk for violence was increased by earlier antisocial behavior (e.g., prior violence, truancy, nonviolent delinquency), attention problems, family conflict, low school commitment, and living in a neighborhood where young people were in trouble. Direct protective factors at ages 10-12 years include a low level of attention problems, low risk-taking, refusal skills, school attachment, and low access and exposure to marijuana at ages 10-12 years. Multivariate regressions showed neighborhood risk factors to be among the most salient and consistent predictors of violence after accounting for all other variables in the tested models. Relatively few direct protective factors were identified in these statistical tests, suggesting the need for further review and possible refinement of the measures and methods that were applied. Implications provide important information for programs and policy. Copyright © 2012 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

Objectives To determine whether family structure (polygamous or monogamous) is associated with sexual activity among school students in Nigeria. Design Cross sectional school survey with a two stage, clustered sampling design. Participants 4218 students aged 12-21 years attending 39 schools in Plateau state, Nigeria. Responses from 2705 students were included in the analysis. Main outcome measure Report of ever having had sexual intercourse. Variables of interest included sexual history, age, sex, religion, family polygamy, educational level of parents, having a dead parent, and sense of connectedness to parents and school. Results Overall 909 students (34%) reported ever having had sexual intercourse, and 1119 (41%) reported a polygamous family structure. Sexual activity was more common among students from polygamous families (42% of students) than monogamous families (28%) (χ2=64.23; P<0.0001). Variables independently associated with sexual activity were male sex (adjusted odds ratio 2.52 (95% confidence interval 2.05 to 3.12)), older age (1.62 (1.24 to 2.14)), lower sense of connectedness with parents (1.87 (1.48 to 2.38)), having a dead parent (1.59 (1.27 to 2.00)), family polygamy (1.58 (1.29 to 1.92)), lower sense of connectedness with school (1.25 (1.09 to 1.44)), and lower educational level of parents (1.14 (1.05 to 1.24)). Multistep logistic regression analysis showed that the effect of polygamy on sexual activity was reduced by 27% by whether students were married and 22% by a history of forced sex. Conclusions Secondary school students in Nigeria from a polygamous family structure are more likely to have engaged in sexual activity than students from a monogamous family structure. This effect is partly explained by a higher likelihood of marriage during adolescence and forced sex. Students' sense of connectedness to their parents and school, regardless of family structure, decreases the likelihood of sexual activity, and fostering this sense may help reduce risky sexual behaviour among Nigerian youth. What is already known on this topicIn 2000 Nigeria developed a national health policy aimed at preventing behaviour among adolescents leading to sexually transmitted infections (including HIV), pregnancy, and dropout from schoolEffective interventions in Nigeria have been hampered by inadequate information on contextual factors associated with sexual behaviour of adolescentsIn Western countries adolescents' sense of connectedness to their parents and to school is inversely associated with risky sexual behaviour, but these effects may differ in countries where polygamy is prevalent and where school attendance is lowWhat this paper addsA polygamous family structure is associated with early sexual activity among adolescents, an effect partly explained by a higher likelihood of marriage and history of forced sexual intercourseA greater sense of connectedness to parents and school decreases the likelihood of sexual activity, regardless of family structure PMID:12511453

Based on the National Highway Traffic Safety Association's (NHTSA) Report, fatalities due to distracted driving are on the rise and the highest proportion of fatalities by age group is the 20-29 year old category. To date little has been done to educate college students about the dangers of distracted driving and engage these students in promoting a safe driving culture. Intervening among college students has the potential for making real-time behavior change, can foster a lifetime of safe driving habits among these students, and can help contribute to a culture of safe driving that can be created and sustained through positive messages from peers. The goals of this study were to develop, implement and evaluate a distracted driving presentation for college students to change knowledge, attitude and behavior on distracted driving. A 30-min, multi-media presentation on distracted driving was presented to 19 colleges and universities, totaling 444 college students (mean age 23.7±7.0 years of age, 61% females, 39% males). Students completed three surveys: prior to the workshop (interview 1), immediately after the workshop (interview 2), and 3 months following the workshop (interview 3). We assessed changes between interview 1 and interview 2 and found 15 of the 15 attitude-knowledge based questions significantly improved after the course. In addition, we assessed changes from interviews 1 and 3, and found 11 of the 15 attitude-knowledge based questions maintained their significance. Responses to behavior related questions at three months were also compared to baseline, and significant improvements were found for 12 of the 14 questions. While this study was successful in improving the short-term attitude-knowledge and behaviors on distracted driving, work is needed to sustain (and evaluate) long-term effects.

Assessment of knowledge of melanoma risk factors, prevention, and detection principles in Texas teenagers.

PubMed

Lucci, A; Citro, H W; Wilson, L

2001-05-15

The incidence of melanoma has increased in the past 10 years more rapidly than any other cancer. Exposure to intense solar radiation in youth significantly increases the lifetime risk of developing melanoma. We postulate that teenagers have little awareness of melanoma prevention or detection principles. The purpose of this study was to assess the knowledge of teenagers about melanoma and to identify which age groups are most receptive to altering their sun exposure behaviors. Two hundred and ten examinations testing general knowledge of sun exposure and melanoma were completed and returned by junior high and high school students ages 12 to 18 in Dallas and Houston, Texas. All students completing and returning the examination were provided with the correct answers to the test and a detailed explanation of each of the test items as part of an educational exercise. A second questionnaire was then administered to determine the effect of the educational exercise on future sun exposure practices. Students were divided into two age groups (12 to 15 and >or=16 years old) for comparison of scores on the knowledge examination and responses to behavioral items. Comparison of response rates between age groups was performed using chi(2) analysis. The return rate was 100%, with 109 students age 12-15 years, and 101 students >or=16 years. Seventy-six percent of all respondents sunbathed outdoors, and 18% had used a tanning bed in the past 6 months. Thirty-three percent of students admitted to at least three blistering sunburns in the past. The average score on the knowledge assessment examination was 65% correct for students >or=16 years old and 54% correct for those 12-15 years old. Students 12 to 15 years old were significantly more likely to indicate they planned to change future behaviors regarding performance of skin self-examinations and limiting sun exposure as compared to the older students. A significant number of teenagers have already enhanced their risk for future melanoma by suffering severe sunburns. Students younger than 16 years of age were significantly more likely to indicate they planned to change future behaviors after receiving information about melanoma. The data from this pilot study support education aimed at younger age groups to most effectively achieve risk reduction and prevent future melanomas. Copyright 2001 Academic Press.

2016-01-01

Background In recent years resilience has gained clinical relevance in sociological, psychological, and medical disciplines, and a lot of scales measuring resilience have been developed and have been utilized in the western countries. The aim of the study was to assess the psychometric properties of the Italian version of the 14-item Resilience Scale (RS-14), by describing its validity and reliability. As agreed with the authors of the original English version of the RS-14, it was translated into Italian. Then the standard procedure for back-translation was followed. Methods In total, 150 participants among the nursing and professional education students of the University of Insubria of Varese and health workers of the “ASST dei Sette Laghi-Ospedale di Circolo” of Varese were enrolled. The responses to the questionnaires were collected only from the students and the health workers between the ages of 18 and 65 years who gave their consent to participate in the study from April to September 2015. A subsample of 26 students and health workers was retested on the RS-14, 5 weeks after the first assessment. The questionnaires were handed out to 214 people, and 150 sets of questionnaires (70%) were returned, of which eight were subsequently removed because >60% of the answers were missing. In order to ensure anonymity, every completed questionnaire was identified only via a code. Results No significant differences were found between the mean values of the resilience scores between women (76.1) and men (76.3), with unpaired t-test = −0.08 and P=0.93. Similarly, no difference between resilience scores were found between mean age group of 18–25 years (75.3) and 26–65 years (78.7), with t-test = 1.6. The overall Cronbach’s alpha of the RS-14 is 0.88, P=0.10. The RS-14 is negatively correlated with the Beck Depression Inventory-Primary Care Version and the 12-item General Health Questionnaire and positively correlated with the World Health Organization Quality of Life-Brief Version. The test-retest reliability, assessed on the 26 subjects 5 weeks after the first evaluation, highlighted an intraclass correlation coefficient value equal to 0.65. Factor analysis retains three factors, and it considers the factor loadings >0.40: RS-14-06 (‘I am determined’) is loaded on all the factors and RS-14-12 (‘In an emergency, I am someone people can generally rely on’) is not loaded on any factor. Conclusion This study demonstrates that the Italian RS-14 has psychometric properties with a good level of internal consistency (Cronbach’s alpha = 0.88), an adequate concurrent validity, verified by relationships with the other scales and as it was expected from literature, and an acceptable test-retest reliability.

The Assessing Care of Vulnerable Elders (ACOVE) comprehensive set of quality assessment tools for ill older persons is a standard designed to measure overall care delivered to vulnerable elders (ie, those aged > or =65 years) at the level of a health care system or plan. The goal of this research was to quantify the pretest and posttest results of medical students and house staff participating in a pharmacotherapist-led educational intervention that focused on the ACOVE quality of pharmacologic care standards. This was a before and after study assessing the knowledge ofACOVE standards following exposure to an educational intervention led by a pharmacotherapist. It was conducted at the 29-bed Acute Care for Elders (ACE) unit of Maimonides Medical Center, a 705-bed, independent teaching hospital located in Brooklyn, New York. Participants included all medical students and house staff completing a rotation on the ACE unit from August 2004 through May 2005 who completed both the pre-and posttests. A pharmacotherapist provided a 1-hour active learning session reviewing the evidence supporting the quality indicators and reviewed case-based questions with the medical students and house staff. Educational interventions also occurred daily through pharmacotherapeutic consultations and during work rounds. Medical students and house staff were administered the same 15-question, patient-specific, case-based, multiple-choice pre-and posttest to assess knowledge of the standards before and after receiving the intervention. A total of 54 medical students and house staff (median age, 28.58 years; 40 men, 14 women) completed the study. Significantly higher median scores were achieved on the multiple-choice test after the intervention than before (median scores, 14/15 [93.3%] vs 12/15 [80.0%], respectively; P = 0.001). A pharmacotherapist-led educational intervention improved the scores of medical students and house staff on a test evaluating knowledge of evidence-based recommendations for pharmacotherapy in the elderly.

Methods: Participants were 2,571 adolescents (56.1% female), with mean age of 16.6±1.2 years, who were students of public schools in Amazonas. The adolescents answered a questionnaire with sociodemographic questions (sex, age group, school year, study shift, maternal schooling and family income) and related to body weight dissatisfaction, romantic relationships (identified by the relationship status - with or without a partner) and perceived stress (dependent variable). Binary Logistic Regression was used to test the association between perceived stress, body weight dissatisfaction and romantic relationships. The analysis was adjusted by sex and age group. Results: The prevalence of perceived stress was 19.0% (95% confidence interval - 95%CI 17.5-20.3), and was higher among girls (23.2%; 95%CI 21.5-24.5) than boys (13.6%; 95%CI 12.2-14.7). Adolescents with partners (OR 1.76; 95%CI 1.14-2.71) and those who wanted to lose body weight (OR 1.53; 95%IC 1.18-1.98) were more likely to perceive themselves as stressed. Conclusions: There was an association between perceived stress, relationship status and body weight dissatisfaction. Regardless of sex and age group, the adolescents with a partner and those who wanted to lose weight were more likely to perceive themselves as stressed. Girls should receive special attention, as well as adolescents with partners and those who want to lose body weight. PMID:28977133

This randomized, open trial compared regimens including 2 doses (2D) of human papillomavirus (HPV) 16/18 AS04-adjuvanted vaccine in girls aged 9-14 years with one including 3 doses (3D) in women aged 15-25 years. Girls aged 9-14 years were randomized to receive 2D at months 0 and 6 (M0,6; (n = 550) or months 0 and 12 (M0,12; n = 415), and women aged 15-25 years received 3D at months 0, 1, and 6 (n = 482). End points included noninferiority of HPV-16/18 antibodies by enzyme-linked immunosorbent assay for 2D (M0,6) versus 3D (primary), 2D (M0,12) versus 3D, and 2D (M0,6) versus 2D (M0,12); neutralizing antibodies; cell-mediated immunity; reactogenicity; and safety. Limits of noninferiority were predefined as <5% difference in seroconversion rate and <2-fold difference in geometric mean antibody titer ratio. One month after the last dose, both 2D regimens in girls aged 9-14 years were noninferior to 3D in women aged 15-25 years and 2D (M0,12) was noninferior to 2D (M0,6). Geometric mean antibody titer ratios (3D/2D) for HPV-16 and HPV-18 were 1.09 (95% confidence interval, .97-1.22) and 0.85 (.76-.95) for 2D (M0,6) versus 3D and 0.89 (.79-1.01) and 0.75 (.67-.85) for 2D (M0,12) versus 3D. The safety profile was clinically acceptable in all groups. The 2D regimens for the HPV-16/18 AS04-adjuvanted vaccine in girls aged 9-14 years (M0,6 or M0,12) elicited HPV-16/18 immune responses that were noninferior to 3D in women aged 15-25 years.

This study examined spillover between daily family stressors and school problems among 589 ninth-grade students (mean age = 14.9 years) from Mexican, Chinese, and European backgrounds. Spillover was examined using a daily diary methodology in which adolescents reported on their school and family experiences each day for 2 weeks. Analyses using hierarchical linear modeling revealed reciprocal spillover effects between adolescents' daily functioning in the family and school domains that spanned several days. Longitudinal analyses indicated that spillover between family stressors and school problems also occurs across the high school years, from 9th to 12th grade, and that both are predictive of poorer academic performance in 12th grade. These findings have practical implications for adolescents' academic achievement trajectories and general well-being.

To examine demographic and behavioural correlates of unhealthy snack-food consumption among Australian secondary-school students and the association between their perceptions of availability, convenience and intake with consumption. Cross-sectional survey of students' eating, physical activity and sedentary behaviours using validated instruments administered via an online questionnaire. Australian secondary schools across all states/territories. Secondary-school students aged 12-17 years participating in the 2009-10 National Secondary Students' Diet and Activity (NaSSDA) survey (n 12 188). Approximately one in five students (21 %) reported consuming unhealthy snack foods ≥14 times/week ('frequent snackers'). After adjusting for all covariates, older students and those with a BMI of ≥25 kg/m² were less likely to be frequent snackers, while students who reported high fast-food and high sugar-sweetened beverage consumption and those who watched television for >2 h/d were more likely to snack frequently. Furthermore, after adjusting for all covariates and demographic factors, students who agreed that snack foods are usually available at home, convenient to buy and that they eat too many snack foods were more likely to be snacking frequently. Conversely, students who agreed that fruit is a convenient snack were less likely to be frequent snackers. Frequent unhealthy snack-food consumption appears to cluster with other poor health behaviours. Perceptions of availability and convenience are factors most readily amenable to change, and findings suggest interventions should focus on decreasing the availability of unhealthy snack foods in the home and promoting healthier options such as fruit as convenient snacks.

Is adolescence a critical period for learning formal thinking skills? A case study investigating the development of formal thinking skills in a short-term inquiry-based intervention program

NASA Astrophysics Data System (ADS)

Towne, Forrest S.

Current domestic and international comparative studies of student achievement in science are demonstrating that the U.S. needs to improve science education if it wants to remain competitive in the global economy. One of the causes of the poor performance of U.S. science education is the lack of students who have developed the formal thinking skills that are necessary to obtain scientific literacy. Previous studies have demonstrated that formal thinking skills can be taught to adolescents, however only 25% of incoming college freshman have these necessary skills. There is some evidence that adolescence (girls aged 11-13, boys aged 12-14) is a critical period where students must learn formal thinking skills, similar to the critical period that exists for young children learning languages. It is not known whether it is more difficult for students to learn formal thinking skills either prior to or following adolescence. The purpose of this quantitative case study is to determine whether adolescence is a critical period for students to learn formal thinking skills. The study also investigates whether a formal thinking skills focused program can improve students' intelligence. In this study 32 students who had not developed any formal thinking skills, ranging in age from 10-16, underwent an intensive four-week, inquiry-based, formal thinking skill intervention program that focused on two formal thinking skills: (1) the ability to control and exclude variables; and (2) the ability to manipulate ratios and proportionalities. The students undergoing the training were matched with control students by age, gender, formal thinking skill ability, and intelligence. The control group attended their traditional science course during the intervention periods. The results of the study showed that the intervention program was successful in developing students' formal thinking skills. The pre-adolescents (males, age 10-11, females, age 10) were unable to learn formal thinking skills. The data indicated that there is not a significant difference between adolescents and post-adolescents (up to 16-years-old) ability to learn formal thinking skills. Both groups (adolescent and post-adolescent) showed improvement in their formal thinking skill ability after the intervention. The intervention also demonstrated evidence of improving students' intelligence scores.

[Testis volume, pubic hair development and spermarcheal age in urban Chinese boys].

PubMed

Hua-mei, M A

2010-06-01

There is a trend that puberty is starting earlier in the 21st century, which is primarily based on studies of girls. The assessment of pubertal stages in the individual child is useful only if recent and reliable reference data from the same population are available for comparison. However, nationally representative pubertal data for Chinese boys in China are lacking. The aim of this study was to investigate the current pubertal development in healthy urban Chinese boys. A cross-sectional study of the pubertal development of a sample of 19,054 urban Chinese boys aged 3 - 19.83 years was conducted between 2003 and 2005. Testicular volume was determined with a Prader orchidometer. Pubic hair development was assessed according to the Tanner method. Data on spermarche were collected by the status quo method. Probit analysis was used to calculate the median age and 95% CI for onset of testicular and pubic hair development and spermarche. A testicular volume greater than or equal to 4 ml was taken as a definite sign of the onset of puberty. Mean ages for sexual development in boys were compared with other published series, while the spermarcheal age was compared to those in the similar population of the five National Surveys on Students Constitution and Health undertaken since 1979 in China. At the age of 9 years, 12.99% of the boys had a testicular volume 4 ml or more. The median age of onset of puberty as indicated by a testicular volume of 4 ml or more was 10.55 (95% CI 10.27 - 10.79) years. The median age for onset of pubic hair development (PH(2)) and spermarche was 12.78 (95% CI 12.67 - 12.89) years and 14.05 (95%CI 13.80 - 14.32) years, respectively. There was a highly significant downward secular trend for spermarcheal age of Chinese boys since 1979. Pubertal onset as indicated by testicular development in urban Chinese boys is earlier than currently used norms. Age of testicular development is among the earliest medians recorded in the world population, while onset of pubic hair development is among the oldest ones. Secular downward change of sexual maturation as indicated by initiation of spermarche has been significant since 1979.

Adolescents' alcohol consumption is a public health concern in Sweden as well as in many other countries. Underage drinking is associated with increased risks of alcohol-related injuries, risky sexual behaviours and dependence later in life. Different strategies have been used in the effort to prevent this behaviour, and to postpone the onset of alcohol. The Strengthening Families Programme 10-14 (SFP 10-14) from the USA has been highlighted as one of the more effective prevention programmes. The aim of the present article was to evaluate the effectiveness of a culturally adapted Swedish version of the SFP 10-14. This was a cluster randomized controlled trial including 587 sixth-grade students (age 12) and their parents in 19 elementary schools in Stockholm. Schools were randomly assigned to either control (9 schools, 216 students) or to the family skills training intervention (10 schools, 371 students). The SFP Swedish version consisted of two parts with seven and five sessions, respectively, held separately for youths and parents except two joint family sessions. Measures of students' self-reported episodes of drunkenness, smoking, illicit drug use and other norm-breaking behaviours were collected at baseline (March 2003) and at three subsequent yearly surveys. Data were analysed using multilevel models with an intention-to-treat approach. No preventive effects were found for smoking, alcohol and illicit drug use and other norm-breaking behaviours, nor did moderators affect the outcome. The Swedish version of the SFP 10-14 was not effective in preventing youths' substance use in a Swedish context. © The Author 2013.

To describe School Function Assessment (SFA) outcomes after 6 months of school-based physical therapy and the effects of age and gross motor function on outcomes. Within 28 states, 109 physical therapists and 296 of their students with disabilities, ages 5 to 12 years, participated. After training, therapists completed 10 SFA scales on students near the beginning and end of the school year. Criterion scores for many students remained stable (46%-59%) or improved (37%-51%) with the most students improving in Participation and Maintaining/Changing Positions. Students aged 5 to 7 years showed greater change than 8- to 12-year-olds on 5 scales. Students with higher gross motor function (Gross Motor Function Classification System levels I vs IV/V and II/III vs IV/V) showed greater change on 9 scales. Positive SFA change was recorded in students receiving school-based physical therapy; however, the SFA is less sensitive for older students and those with lower functional movement.

Background: This study aims to explore the frequency of aggressive behaviors among a nationally representative sample of Iranian children and adolescents. Methods: This nationwide study was performed on a multi-stage sample of 6–18 years students, living in 30 provinces in Iran. Students were asked to confidentially report the frequency of aggressive behaviors including physical fighting, bullying and being bullied in the previous 12 months, using the questionnaire of the World Health Organization Global School Health Survey. Results: In this cross-sectional study, 13,486 students completed the study (90.6% participation rate); they consisted of 49.2% girls and 75.6% urban residents. The mean age of participants was 12.47 years (95% confidence interval: 12.29, 12.65). In total, physical fight was more prevalent among boys than girls (48% vs. 31%, P < 0.001). Higher rates of involvement in two other behaviors namely being bullied and bulling to other classmates had a higher frequency among boys compared to girls (29% vs. 25%, P < 0.001 for being bullied) and (20% vs. 14%, P < 0.001 for bulling to others). Physical fighting was more prevalent among rural residents (40% vs. 39%, respectively, P = 0.61), while being bullied was more common among urban students (27% vs. 26%, respectively, P = 0.69). Conclusions: Although in this study the frequency of aggressive behaviors was lower than many other populations, still these findings emphasize on the importance of designing preventive interventions that target the students, especially in early adolescence, and to increase their awareness toward aggressive behaviors. Implications for future research and aggression prevention programming are recommended. PMID:25789141

Being bullied is a well-recognized trauma for adolescents. Bullying can best be understood through an ecological framework since bullying or being bullied involves risk factors at multiple contextual levels. The purpose of the study was to identify the risk and protective factors that best differentiate groups along with the outcome variable of interest (being bullied) using Classification and Regression Tree (CART) analysis. The study used the Health Behavior in School-Aged Children (HBSC) data collected from a nationally representative sample of students in grades six through ten during the 2005–2006 school years. This study identified that for adolescents 12 and younger, lower parental support is a critical risk factor associated with bullying and among those 13 to 14 with lower parent support, adolescent with higher academic pressure reported experiencing more bullying. For the older group of adolescents (aged 15 and older), school related factors were identified to increase the risk level of being bullied. There was a critical age (15 years old) for implementing victimization interventions to reduce the damage from being bullied. Service providers working with adolescents aged 14 and less should focus more on family-oriented intervention and those working with adolescents aged 15 and more should offer peer- or school-related interventions.

Sex-mental health of adolescence.

Ye, G

1990-09-20

From the answers to the questionnaire on mental health of adolescents by 4366 middle school students in Beijing, we can see that the knowledge about masturbation, emission, menstruation, the easiest time period of pregnancy and at which age males get fertile is very limited, especially to the question "at which time females are easy to be pregnant," only 7.21% of the students answered correctly. The % of girls who had advanced preparation at menarche, knowing that menstruation is a normal phenomenon is 55.7%. As for the resources of knowledge of emission and menstruation, almost half of the girls' knowledge on menstruation is from their mothers, followed by friends and peers. Newspapers and magazines rank 1st of the resources of knowledge emission, followed by friends and peers. Only 10% of the knowledge is learned from teachers. It suggests that school sex education has a long way to go. What we must pay attention to is that some of the students are ignorant of emission and menstruation, some of them have totally erroneous views. For example, 5.2% of the rural girls believed that menstruation is "bleeding from the urethra" while 15 students answered that menstruation is "bleeding from the anus." About 1.4 to 1.3 of the students knew that syphilis and gonorrhea were sexually transmitted diseases; fewer students knew that AIDS was a sexually transmitted disease. 25% were not afraid of AIDS; 30% did not know that AIDS could be transmitted through sexual intercourse. The results suggest that sex education needs to be strengthened. With regard to the behavior of adolescents, 42.14% of boys and 30.29% of girls have the experience of masturbation. 52.8% of male senior high schools students had masturbated once. The rate of students who are in love is 10-12% for boys and girls. The % of students who consider that dating is not necessarily bad while studying are: 36.9% for junior high school boys; 42.12% for girls; 63.54% for senior high school boys and 65.94% for the girls.

Hope, connectedness, and action: responses of adolescents and young adults to the threat of nuclear war

Fernald, M.C.

This study undertook to assess the degree to which a person's sense of interconnectedness with others may have a mediating effect on whether one reacts to the consciousness of nuclear threat with feelings of despair (helplessness and hopelessness) or with a sense of empowerment (hope, efficacy, and action for change). Subjects included 119 public high school students and 14 Friends' school students, ranging from 12-18 years of age; 58 university students ranging from 18-25 years of age; and 24 parents of public school students, 10 adult Friends, and 38 members of Physicians for Social Responsibility, ranging from 20-83 years ofmore » age. A self-rating questionnaire was administered to assess subjects' conscious level of concern about nuclear issues, feelings of connectedness with others in general and about nuclear concerns, feelings of hope and efficacy in general and with regard to nuclear issues, and participation in activities reflecting concerns about nuclear threat. Correlational analyses (multiple regression, Spearman Rho, Kendall's Tau) showed that general feelings of hope, level of activity, and feelings of connectedness about nuclear concerns were the best predictors of hope about nuclear concerns. Conscious level of concern and feelings of connectedness about nuclear concerns, along with age and SES were the best predictors of an active response to nuclear threat; additionally, parents' level of concern about nuclear issues was predictive of their children's degree of activity in response to nuclear threat. Adolescents' level of concern and degree of connectedness with others was predicted by their parents' degree of connectedness.« less

The undertaken research aimed at determining the frequency of deliberate self-injurious behaviour (D-SIB) among the students of secondary schools and also the analysis of the frequency of repeated Non-Suicidal Self-Injury (NSSI) occurrences in accordance with DSM-5 criteria in reference to the age and sex in the studied population. The data was collected via survey method according to the questionnaire prepared in compliance with the criteria DSM-5 and Self-Harm Inventory. The study included randomly selected students: 1193 boys and 1027 girls in Bialystok aged 12 and 19 (average age ± SD:16.8 ± 1.65). Statistical analysis of the data was carried out using the application Statistica 10.0 PL, StatSoft. These results indicate that D-SIB and NSSI affect both sexes. In the studied group 8.3 % of students engage in deliberate self-injurious behaviour. The percentage of NSSI was 4.8% (6.3% in the group of boys, 3.2 % among girls; p(Chi2)=0.01). Self-cutting was most common among 15-year-old pupils ((D-SIB:14.75%; NNSI:8.1%). The majority of respondents (82% of girls and 74% of boys) revealed that as a result of self-injury behaviour they experience relief. Conducting further research in the area of NSSI seems to be crucial due to chronicity and prevalence as well as the fact that numerous repeated self-injuries bringing relief or causing positive state of mind might indicate a mechanism similar to an addiction syndrome in adolescence.

Students aged 13 and 14 y, in a region in northern Norway with high blood cholesterol levels and high mortality from coronary heart disease (CHD) in the adult population, were studied with respect to lifestyle, dietary habits, nutritional intake and blood lipids including fatty acids in serum. The students came from a coastal community with seawater fish as an important part of the traditional diet, and an inland community with meat from reindeer as a major constituent of the diet. To investigate whether the traditional diet was maintained among the adolescents and to evaluate the lifestyle and blood lipids. The study was followed up after 1 y. The adolescents from the coastal region did not maintain the traditional diet. In the inland region the students had a high intake of meat, probably reflecting the traditional food culture. The inland boys had higher mean body mass index (BMI) than the coastal boys, and 12% had BMI>28, as compared to none of the coastal boys. Other findings showed that the students had higher levels of blood cholesterol than in the south of Norway and several other countries (about 25% had total cholesterol >5.2 mmol/l), higher intake of dietary sugar and fat than the national recommendations and little intake of seawater fish with corresponding low levels of n-3 fatty acids. This did not change after 1 y of follow up. Some 10-20% reported daily smoking and 8-13% reported that they rarely or never did physical exercise. About 30% of the students presented no factors negatively related to development of cardiovascular disease. The findings demonstrate, in the majority of students at the age of 13 and 14 y, the appearance of factors contributing to development of cardiovascular disease (CHD). This study was supported by the program 'Medisinsk forskning i Finnmark, University of Tromsø'.

Objectives. We investigated the frequency of alcohol ads at all 113 subway and streetcar stations in Boston and the patterns of community exposure stratified by race, socioeconomic status, and age. Methods. We assessed the extent of alcohol advertising at each station in May 2009. We measured gross impressions and gross rating points (GRPs) for the entire Greater Boston population and for Boston public school student commuters. We compared the frequency of alcohol advertising between neighborhoods with differing demographics. Results. For the Greater Boston population, alcohol advertising at subway stations generated 109 GRPs on a typical day. For Boston public school students in grades 5 to 12, alcohol advertising at stations generated 134 GRPs. Advertising at stations in low-poverty neighborhoods generated 14.1 GRPs and at stations in high-poverty areas, 63.6 GRPs. Conclusions. Alcohol ads reach the equivalent of every adult in the Greater Boston region and the equivalent of every 5th- to 12th-grade public school student each day. More alcohol ads were displayed in stations in neighborhoods with high poverty rates than in stations in neighborhoods with low poverty rates. PMID:21852632

Drawing on a 2-wave longitudinal sample spanning 40 years from childhood (age 12) to middle adulthood (age 52), the present study was designed to examine how student characteristics and behaviors in late childhood (assessed in Wave 1 in 1968) predict career success in adulthood (assessed in Wave 2 in 2008). We examined the influence of parental socioeconomic status (SES), childhood intelligence, and student characteristics and behaviors (inattentiveness, school entitlement, responsible student, sense of inferiority, impatience, pessimism, rule breaking and defiance of parental authority, and teacher-rated studiousness) on 2 important real-life outcomes (i.e., occupational success and income). The longitudinal sample consisted of N = 745 persons who participated in 1968 (M = 11.9 years, SD = 0.6; 49.9% female) and 2008 (M = 51.8 years, SD = 0.6; 53.3% female). Regression analyses and path analyses were conducted to evaluate the direct and indirect effects (via education) of the predictors on career success. The results revealed direct and indirect influences of student characteristics (responsible student, rule breaking and defiance of parental authority, and teacher-rated studiousness) across the life span on career success after adjusting for differences in parental SES and IQ at age 12. rd (c) 2015 APA, all rights reserved).

University students are potentially important targets for the promotion of healthy lifestyles as this may reduce the risks of lifestyle-related disorders later in life. This cross-sectional study examined differences in eating behaviours, dietary intake, weight status, and body composition between male and female university students. A total of 584 students (59.4% females and 40.6% males) aged 20.6 +/- 1.4 years from four Malaysian universities in the Klang Valley participated in this study. Participants completed the Eating Behaviours Questionnaire and two-day 24-hour dietary recall. Body weight, height, waist circumference and percentage of body fat were measured. About 14.3% of males and 22.4% of females were underweight, while 14.0% of males and 12.3% of females were overweight and obese. A majority of the participants (73.8% males and 74.6% females) skipped at least one meal daily in the past seven days. Breakfast was the most frequently skipped meal. Both males and females frequently snacked during morning tea time. Fruits and biscuits were the most frequently consumed snack items. More than half of the participants did not meet the Malaysian Recommended Nutrient Intake (RNI) for energy, vitamin C, thiamine, riboflavin, niacin, iron (females only), and calcium. Significantly more males than females achieved the RNI levels for energy, protein and iron intakes. This study highlights the presence of unhealthy eating behaviours, inadequate nutrient intake, and a high prevalence of underweight among university students. Energy and nutrient intakes differed between the sexes. Therefore, promoting healthy eating among young adults is crucial to achieve a healthy nutritional status.

The relationship between screen time (ST) and the frequency of snack consumption in a national sample of Iranian children and adolescents was assessed. The present nationwide survey was conducted on 14,880 school students living in urban and rural areas of 30 provinces in Iran. Trained healthcare providers conducted the physical examination and completed the questionnaire of the World Health Organization - Global School-Based Student Health Survey (WHO-GSHS). The association between ST (total time spent watching TV and using a computer in leisure time) and the frequency of snack consumption was determined using ordinal logistic regression analysis. The subjects were 13,486 students out of the 14,880 invited including 50.8% boys. The mean (SD) age of participants was 12.47 (3.36) years. In multivariate models, for students who had prolonged ST (more than 4 h/day), the odds of daily consumption of sweets (odds ratio, OR 1.25; 95% CI 1.14-1.4), salty snacks (OR 1.6; 95% CI 1.5-1.76), soft drinks (OR 1.52; 95% CI 1.4-1.7), canned fruit juice (OR 1.3; 95% CI 1.2-1.4), and fast food (OR 1.53; 95% CI 1.4-1.7) were higher compared to those with low ST. Furthermore, the odds of daily consumption of milk in students who had prolonged ST (more than 4 h/day) were lower compared to those with low ST (OR 0.9; 95% CI 0.8-0.99). Prolonged time spent watching TV and using a computer during leisure time might be associated with unhealthy dietary habits. Moreover, inactivity induced by prolonged ST may also lead to unhealthy dietary habits and in turn excess weight in children and adolescents.

To examine demographic and behavioural correlates of high consumption of soft drinks (non-alcoholic sugar-sweetened carbonated drinks excluding energy drinks) among Australian adolescents and to explore the associations between high consumption and soft drink perceptions and accessibility. Cross-sectional self-completion survey and height and weight measurements. Australian secondary schools. Students aged 12-17 years participating in the 2012-13 National Secondary Students' Diet and Activity (NaSSDA) survey (n 7835). Overall, 14 % of students reported consuming four or more cups (≥1 litres) of soft drinks each week ('high soft drink consumers'). Demographic factors associated with high soft drink consumption were being male and having at least $AU 40 in weekly spending money. Behavioural factors associated with high soft drink consumption were low fruit intake, consuming energy drinks on a weekly basis, eating fast foods at least once weekly, eating snack foods ≥14 times/week, watching television for >2 h/d and sleeping for <8 h/school night. Students who perceived soft drinks to be usually available in their home, convenient to buy and good value for money were more likely to be high soft drink consumers, as were students who reported usually buying these drinks when making a beverage purchase from the school canteen/vending machine. High soft drink consumption clusters with other unhealthy lifestyle behaviours among Australian secondary-school students. Interventions focused on reducing the availability of soft drinks (e.g. increased taxes, restricting their sale in schools) as well as improved education on their harms are needed to lower adolescents' soft drink intake.

This study aims to compare the dietary and physical activity (PA) habits in a nationally representative sample of Iranian children and adolescents based on their family and regional socioeconomic status (SES). This nationwide study was conducted on 14,880 students, aged 6-18 years, and one of their parents living in urban and rural areas of 30 provinces in Iran. Data regarding PA, screen time and dietary habits were recorded using two sets of questionnaires for both students and their parents. The results were compared according to the SES of the family and the living region. Overall, 13,486 students completed the study (90.6% participation rate) with a mean age of 12.5 (95% CI: 12.3-12.6) years. Comparing family SES, the level of PA was similar in the three SES groups. The total screen time, working computer with and watching TV was significantly higher in those with higher family SES (P < 0.05). Consumption of meat, dairy products, rice, fruit, and vegetables was significantly higher in families with higher SES. Consumption of salty snacks and sweet drinks was significantly lower in families with higher SES level. Sedentary lifestyle was more prevalent in regions with higher SES. The dietary habits of inhabitants of regions with low SES was similar to that reported for individuals with low family SES. Both family and regional SES might impact lifestyle habits from early life. Participants with higher SES had healthier dietary habits but lower PA level than their counterparts with lower SES. Socioeconomic disparities should be considered for public health interventions aiming to improve lifestyle habits.

To analyze the prevalence of asthma and asthma symptoms in students of two distinct age brackets residing in the city of Tangará da Serra, Brazil. Cross-sectional, population-based study of the prevalence of asthma in children from 6 to 7 years of age and adolescents from 13 to 14, using the standardized International Study of Asthma and Allergies in Childhood, phase 1 questionnaire, validated for use in Brazil. Students who responded affirmatively to question 2 (presence of wheezing in the preceding 12 months) were classified as suffering from asthma. The study comprised 3,362 students, of whom 1,634 (48.6%) were children and 1,728 (51.4%) were adolescents. Of the 1,634 children, 816 (49.9%) were male, and 818 (50.1%) were female. Of the 1,728 adolescents, 773 (45.0%) were male, and 955 (55.0%) were female. The prevalence of asthma among the children was 25.2%, whereas that among the adolescents was 15.9% (chi2 = 8.34; p = 0.00). The children presented higher prevalences of the following symptoms of asthma than did the adolescents: wheezing ever (54.3%), nocturnal dry cough (43.9%), wheezing in the preceding 12 months (25.2%), and from 1 to 3 attacks of wheezing in the preceding 12 months (19.1%). There were no differences between the two groups regarding physician-diagnosed asthma (approximately 4.5%). There were no statistical differences regarding the prevalence of asthma by gender in the two groups. Tangará da Serra has a high prevalence of asthma in children and adolescents, and this result is compatible with other studies carried out in Brazil and Latin America using the same methodology.

A large drop in atmospheric [sup 14]C/[sup 12]C and reduced melting in the younger dryas, documented with [sup 230]Th ages of corals

Paired carbon-14 ([sup 14]C) and thorium-230 ([sup 230]Th) ages were determined on fossil corals from the Huon Peninsula, Papua New Guinea. The ages were used to calibrate part of the [sup 14]C time scale and to estimate rates of sea-level rise during the last deglaciation. An abrupt offset between the [sup 14]C and [sup 230]Th ages suggests that the atmospheric [sup 14]C/[sup 12]C ratio dropped by 15 percent during the latter part of and after the Younger Dryas (YD). This prominent drop coincides with greatly reduced rates of sea-level rise. Reduction of melting because of cooler conditions during the YDmore » may have caused an increase in the rate of ocean ventilation, which caused the atmospheric [sup 14]C/[sup 12]C ratio to fall. The record of sea-level rise also shows that globally averaged rates of melting were relatively high at the beginning of the YD. Thus, these measurements satisfy one of the conditions required by the hypothesis that the diversion of meltwater from the Mississippi to the St. Lawrence River triggered the YD event. 41 refs., 5 figs., 1 tab.« less

The role of timing of maltreatment and child intelligence in pathways to low symptoms of depression and anxiety in adolescence.

Harpur, Lisa Jane; Polek, Ela; van Harmelen, Anne-Laura

2015-09-01

Research indicates that childhood maltreatment is strongly associated with high levels of adolescent depression and anxiety symptoms. Using LONGSCAN data and taking into account the range of family characteristics related to adversity (poverty, primary caregiver substance abuse) and protective factors (living with biological mother and father), the present study assessed the complex resilience process in which child intelligence (age 6) mediated the relationship between early childhood maltreatment (age 0-4) and adolescent symptoms of depression and anxiety (age 14). We also assessed if mid (age 6-8) and late (age 10-12) childhood maltreatment moderated this mediation. We found that mid-childhood intelligence mediated the negative effect of early childhood maltreatment (age 0-4) on anxiety symptoms (age 14), but not on depressive symptoms (age 14). We also found the effect of timing of maltreatment: early childhood maltreatment (age 0-4) predicted more anxiety symptoms in adolescence, whereas late childhood/early adolescent (age 10-12) maltreatment predicted more symptoms of depression in adolescence. In addition, mid (age 6-8) and late (age 10-12) childhood maltreatment dampened the protective effect of IQ (age 6) against anxiety (age 14). In sum, current evidence shows that low anxiety and depression symptoms in adolescence following childhood maltreatment was achieved through different pathways, and that early and late childhood/early adolescence were more sensitive periods for development of psychopathology related to depression and anxiety in adolescence.

This report presents data on US school enrollment from the October supplements to the Current Population Survey, collected in 1984 and 1985. The statistical tables present data for students attending nursery school through college by age, race, Spanish origin, sex, marital status, household relationship, residence, and family income. The tables are limited to enrollment of the civilian noninstitutional population in regular schools, and thus exclude enrollments in vocational schools, adult education classes, and special schools. Elementary and high school enrollment was 40.8 million in 1985, down from 46.1 million in 1975. Enrollment rates of 6- to 15-year-olds remained essentially the same, with changes in enrollments mirroring changes in the size of the school-age population. The enrollment rate of 16- and 17-year-olds grew slightly. There were 12.5 million college students in 1985, 15% above enrollment a decade earlier. The college enrollment rate of Black 18- to 21-year-olds did not change from 1975 to 1985; it remained at 25%, while the proportion of the age group who were high school drop-outs declined by 10% to 17%. Preprimary enrollment of 3- to 5-year-olds was 5.9 million in 1985, an 18% increase over the number enrolled a decade earlier, due to an increase in the population of 3- to 5-year-olds and a rise in their enrollment rate. In 1985, 38% of kindergarten students attended full-day, up from 14% in 1970. In 1985, 34% of nursery school students attended full-day, compared with 27% in 1970.

The study investigated the effects of a Special Olympics (SO) Unified Sport (UNS) soccer program on anthropometry, physical fitness and soccer skills of male youth athletes with and without intellectual disabilities (ID) who participated in a training group (TRG) and in a comparison group (CG) without specific training. Youth with ID (WID) were randomly selected out of all the students between the ages 12 and 15, with a diagnosis of educable mental retardation and no secondary disabilities, who were attending a special education school. Participants without ID (WoID) were randomly selected from a regular secondary school out of the same age groups of male students. All participants were given permission by their parents or guardians to participate in the study. Participants in the TRG included 23 youth WID and 23 youth WoID. Mean ages were = 14.1 (SD = 1.1) and 13.2 (SD = 0.79) respectively. Fifteen WID, and 15 WoID comprised the CG. Mean ages were 14.51 (SD = 0.81) and 13.78 (SD = 0.49) respectively. Prior to and following the program measurements were conducted, and data were collected on students' anthropometric and fitness components of the Brockport physical fitness test as well as a soccer skill performance based on the SO soccer skill test. Participants in the TRG trained 8 weeks, 1.5h per session, three times per week, in an after-school soccer program. CG did not participate in any sports program outside of the school physical education class. Dependent t tests and effect size calculations revealed that SO athletes and non-disabled partners scored significantly higher with regard to physical fitness and football skills in most variables compared with their CG. This Unified Program was successful in increasing fitness and soccer skill performance of youth WID as well as of those WoID. Copyright © 2012 Elsevier Ltd. All rights reserved.

Background In addition to the benefits on physical and mental health, cardiorespiratory fitness has shown to have positive effects on cognition. This study aimed to investigate the relationship between cardiorespiratory fitness and body weight status on academic performance among seventh-grade students. Methods Participants included 1531 grade 7 students (787 male, 744 female), ranging in age from 12 to 14 years (Mage = 12.3 ± 0.60), from 3 different cohorts. Academic performance was measured using the marks students had, at the end of their academic year, in mathematics, language (Portuguese), foreign language (English), and sciences. To assess cardiorespiratory fitness the Progressive Aerobic Cardiovascular Endurance Run, from Fitnessgram, was used as the test battery. The relationship between academic achievement and the independent and combined association of cardiorespiratory fitness/weight status was analysed, using multinomial logistic regression. Results Cardiorespiratory fitness and weight status were independently related with academic achievement. Fit students, compared with unfit students had significantly higher odds for having high academic achievement (OR = 2.29, 95% CI: 1.48-3.55, p < 0.001). Likewise, having a normal weight status was also related with high academic achievement (OR = 3.65, 95% CI: 1.82-7.34, p < 0.001). Conclusions Cardiorespiratory fitness and weight status were independently and combined related to academic achievement in seventh-grade students independent of the different cohorts, providing further support that aerobically fit and normal weight students are more likely to have better performance at school regardless of the year that they were born.

This study was designed to examine the association between sleep duration and being overweight/obese in primary, middle, and high school students. This was a multiple cross-sectional study using data from the 2010 and 2014 National Survey on Students’ Constitution and Health (CNSSCH). A total of 23,602 students aged 7⁻18 years were enrolled in this study. The prevalence of being overweight and obese—stratified by age, gender, and sleep duration—in 2010 and 2014 were compared. Sleep duration was categorized as <7 h, ≥7 to 8 h, ≥8 to 9 h, and ≥9 h. Overweight and obesity were defined according to the cut-point criteria in China. Multivariable logistic regression results in 2010 and 2014 revealed that students sleeping <7 h and aged 7⁻12 years had an increased risk of becoming overweight/obese. In 2010, the adjusted prevalence ratios of overweight for 7⁻12-year-old students sleeping <9 h was 1.196 (95%CI: 1.004⁻1.424) and 13⁻15-year-old students sleeping <8 h was 1.265 (95%CI: 1.023⁻1.565). In 2014, the adjusted prevalence ratios of overweight and obesity for 7⁻12-year-old students sleeping <9 h were 1.295 (95%CI: 1.091⁻1.537) and 1.231 (95%CI: 1.045⁻1.449); 16⁻18-year-old students sleeping <7 h were 1.530 (95%CI: 1.239⁻1.888) and 1.585 (95%CI: 1.270⁻2.081). Our study revealed that different levels of sleep curtailment increased the risk of becoming overweight/obesity in different age groups of students.

There is a paucity of recent data on Chinese childhood overweight and underweight prevalence especially since 2004. The purpose of this study was to examine trends in underweight and overweight/obesity ("overweight" hereafter) prevalence and energy balance-related behaviors of Chinese youth from 2004 to 2009. Data from the China Health and Nutrition Survey, 2004-2009 (N = 4,061 students aged 6-18 years), were analyzed. Trained health workers took anthropometric measures at the participant's house or at a local clinic following a reference protocol recommended by the World Health Organization. The international age- and sex-specific body mass index reference standard proposed by the International Obesity Task Force was used to define underweight and overweight children in this study. Among 6- to 11-year-old boys, underweight prevalence increased from 14.5% (2004) to 20.1% (2009, p = 0.068). Among 12- to 18-year-old boys, however, overweight prevalence increased from 7.5 to 12.6% (p = 0.034). From 2004 to 2009, after-school sedentary behavior increased from 2.3 to 3.4 h/day for 6- to 11-year-olds (p < 0.001) and from 2.2 to 3.1 h/day for 12- to 18-year-olds (p < 0.01). Meanwhile, the total energy intake decreased 7% for 6- to 11-year-olds (p < 0.05) and 10% for 12- to 18-year-olds (p < 0.01). Both underweight and overweight Chinese students are increasing, with underweight increases more pronounced in 6- to 11-year-olds and overweight increases more pronounced in 12- to 18-year-olds. Nationwide efficacious interventions are needed that improve the diet, decrease sedentary behavior, and encourage a healthy and realistic body image in Chinese youth.

Background: Cannabis use can have serious detrimental effects in children and adolescents. It is therefore important to continually assess the use of cannabis among young people in order to inform prevention efforts. We assessed the prevalence of cannabis use among middle and high school students in Ontario and examined its association with demographic and behavioural factors. Methods: Data were obtained from the 2015 Ontario Student Drug Use and Health Survey, a province-wide school-based survey of students in grades 7 through 12. Analyses included a representative sample of 9920 middle and high school students. Bivariate cross-tabulations and logistic regression analyses were used to investigate the factors associated with cannabis use. Results: Overall, 21.5% and 13.9% of students reported using cannabis in the previous year and previous month, respectively. The conditional probability that an adolescent who reported cannabis use in the previous year would report daily use was 12.5%. There was a significant dose-response gradient with age, with older students being more likely to use cannabis than younger students. In multivariable analyses, being in grades 10 through 12 (odds ratios [ORs] ranged from 3.71 to 3.85), being black (OR 2.67 [95% confidence interval (CI) 1.76-4.05]), using tobacco cigarettes (OR 10.10 [95% CI 8.68-13.92]) and being an occasional (OR 5.35 [95% CI 4.01-7.13]) or regular (OR 14.6 [95% CI 10.8-19.89]) alcohol user were associated with greater odds of cannabis use. Being an immigrant was associated with lower odds of cannabis use (OR 0.55 [95% CI 0.39-0.78]). Interpretation: The findings suggest that cannabis use is prevalent among middle and high school students in Ontario and is strongly associated with tobacco cigarette smoking and alcohol consumption. Future research should document trends in cannabis use over time, including its risks, especially when the legalization of recreational cannabis comes into effect. PMID:29367264

Ecological studies support the hypothesis that suicide may be "contagious" (i.e., exposure to suicide may increase the risk of suicide and related outcomes). However, this association has not been adequately assessed in prospective studies. We sought to determine the association between exposure to suicide and suicidality outcomes in Canadian youth. We used baseline information from the Canadian National Longitudinal Survey of Children and Youth between 1998/99 and 2006/07 with follow-up assessments 2 years later. We included all respondents aged 12-17 years in cycles 3-7 with reported measures of exposure to suicide. We included 8766 youth aged 12-13 years, 7802 aged 14-15 years and 5496 aged 16-17 years. Exposure to a schoolmate's suicide was associated with ideation at baseline among respondents aged 12-13 years (odds ratio [OR] 5.06, 95% confidence interval [CI] 3.04-8.40), 14-15 years (OR 2.93, 95% CI 2.02-4.24) and 16-17 years (OR 2.23, 95% CI 1.43-3.48). Such exposure was associated with attempts among respondents aged 12-13 years (OR 4.57, 95% CI 2.39-8.71), 14-15 years (OR 3.99, 95% CI 2.46-6.45) and 16-17 years (OR 3.22, 95% CI 1.62-6.41). Personally knowing someone who died by suicide was associated with suicidality outcomes for all age groups. We also assessed 2-year outcomes among respondents aged 12-15 years: a schoolmate's suicide predicted suicide attempts among participants aged 12-13 years (OR 3.07, 95% CI 1.05-8.96) and 14-15 years (OR 2.72, 95% CI 1.47-5.04). Among those who reported a schoolmate's suicide, personally knowing the decedent did not alter the risk of suicidality. We found that exposure to suicide predicts suicide ideation and attempts. Our results support school-wide interventions over current targeted interventions, particularly over strategies that target interventions toward children closest to the decedent.

Are impulsive adolescents differentially influenced by the good and bad of neighborhood and family?

Barker, Edward D; Trentacosta, Christopher J; Salekin, Randall T

2011-11-01

Using the differential susceptibility perspective (Belsky & Pluess, 2009) as a guiding frame-work, age 12 neighborhood disadvantage (ND) and family characteristics (parental knowledge) were examined as moderators of the relations between age 12 youth impulsivity and the development (ages 13, 14, and 15) of positive (community activities) and negative (antisocial behavior; ASB) adolescent behavior. An interaction between ND and youth impulsivity (age 12) operated with differential susceptibility, but only for female community activities at age 13: under low levels of ND, impulsive adolescent females engaged in the highest levels of community activities, whereas under high ND, they engaged in the lowest levels. Exploratory analysis showed the association between community activities and ND to be partially related to parents' or adults' engagement in informal social controls (e.g., alerting the police with misbehavior in the neighborhood). Differential susceptibility effects were not identified for: (i) parental knowledge and impulsivity; (ii) ASB (ages 13, 14 or 15); or (iii) community involvement at ages 14 and 15. Findings provide limited evidence for impulsivity as a differential susceptibility phenotype.

Some 12.8 million in the age group 5-15 years are visually impaired from uncorrected or inadequately corrected refractive errors. In Saudi Arabia, the size of this public health problem is not well defined especially among primary schoolchildren. The purpose of this cross-sectional study was to assess the prevalence and pattern of refractive errors among primary school children in Al Hassa, Saudi Arabia.  A total of 2246 Saudi primary school children aged 6 to 14 years of both genders were selected using multistage sampling method form 30 primary schools located in the three different areas of Al Hassa. School children were interviewed to collect demographics and vision data using a special data collection form followed by screening for refractive errors by trained optometrists within the school premises using a standardized protocol. Assessment of visual acuity and ocular motility evaluation were carried out and cover-uncover test was performed. Children detected with defective vision were referred for further examination employing subjective refraction with auto refractometer and objective refraction using streak retinoscopy after 1% cyclopentolate. Of the screened school children (N=2002), the overall prevalence of refractive errors was 13.7% (n=274), higher among females (Odds ratio, OR=1.39, P=0.012) and significantly more among students of rural residence (OR=2.40, P=0.001). The prevalence of refractive errors was disproportionately more among those aged 12-14 years (OR=9.02, P=0.001). Only 9.4% of students with poor vision were wore spectacles for correction. Myopia was the most commonly encountered refractive error among both genders (65.7% of the total errors encountered). Uncorrected refractive errors affected a sizable portion of primary school children in Al Hassa, Saudi Arabia. Primary schoolchildren especially females, rural and older children represents high risk group for refractive errors for which the included children were unaware.

Mak, Kwok-Kei; Ho, Sai-Yin; Day, Jeffrey R

2012-09-01

This study investigates the independent and combined effects of smoking of parents and best friend on smoking and the intention to initiate or quit smoking in adolescents. In this school-based survey, 6,553 Hong Kong students aged 13-18 reported their demographic characteristics, smoking status of themselves, parents, and best friend; and intention to smoke (initiation among never-smokers and reinitiation among ex-smokers) or quit smoking among current smokers. Logistic regression yielded adjusted odds ratios (AORs) of student smoking (current/ever) and intention to smoke or quit smoking for parental (paternal/maternal/both parents vs. none) and best friend (yes vs. no) smoking. Parental smoking and having a smoking best friend were associated with adolescent current smoking, ever smoking, and intention to initiate smoking. Having a smoking best friend was also associated with reinitiating and quitting smoking. The AORs (95% CI) of current smoking for having a smoking best friend, in addition to smoking father, mother, or both were 19.14 (14.36-25.51), 20.38 (12.42-33.43), and 24.18 (15.89-36.77). The respective AORs of ever smoking were 8.30 (6.74-10.22), 8.92 (5.63-14.12), and 11.99 (8.05-17.87). Parental smoking and best friend smoking have independent effects on adolescent smoking behaviors. Their combined effects on current and ever smoking were particularly large. Smoking prevention programs should pay special attention to adolescents with both best friend and parents who smoke.

Experiences in adolescence may have a lasting impact on adulthood. The objective of this study is to evaluate the association between adolescent (12-18 years of age) volunteerism with the incidence of illegal behaviors, arrests, and convictions in adulthood (>18 years of age). We conducted a retrospective cohort study using secondary data from the National Longitudinal Study of Adolescent to Adult Health. Students from grades 7-12 were recruited in 1994-1995 (n = 20,745), and then followed in 2001-2002 (n = 14,322) and in 2008-2009 (n = 12,288). In 2000-2001, participants were retrospectively asked about their volunteering experience from 12 to 18 years of age. Consequently, participants were divided into non-volunteers, self-volunteers, adult-required volunteers, and court-ordered volunteers. Groups were compared for rates of illegal behaviors, arrest, and convictions in adulthood (>18 years of age) using weighted generalized linear mixed negative binomial models while accounting for sampling design. Relative to non-volunteers, self-volunteers reported 11 % fewer illegal behaviors (RR: 0.89, 95 % CI: 0.80, 0.99), 31 % fewer arrests (RR: 0.69, 95 %: 0.57, 0.85), and 39 % fewer convictions (RR: 0.61, 95 % CI: 0.47, 0.79) by age 18-28 years, and 28 % fewer illegal behaviors, 53 % fewer arrests, and 36 % fewer convictions by age 24-34. In comparison the adult-required volunteers also reported fewer arrests and convictions; however, they reported more illegal behaviors than the non-volunteers. The court-ordered volunteers reported higher rates of criminal involvement than the non-volunteers, throughout. This study suggests that volunteering in adolescence may reduce crime involvement in adulthood.

Bortoli, Laura; Bertollo, Maurizio; Vitali, Francesca; Filho, Edson; Robazza, Claudio

2015-06-01

The purpose of this study was to examine the effects of task- and ego-involving climate manipulations on students' climate perception and psychobiosocial (PBS) states in a physical education setting. Two subsamples of female students (N = 108, 14-15 years of age) participated in 12 lessons on either a task- or an ego-involving climate intervention as grounded in the TARGET (tasks, authority, recognition, grouping, evaluation, and time) model. At the end of the treatment, the participants of the ego-involved group reported lower scores in the perceived task-involving climate and higher scores in the perceived ego-involving climate compared with their peers in the task-involved group. Lower scores in pleasant/functional PBS states and higher scores in unpleasant/dysfunctional PBS states were also observed in the ego-involved group as a consequence of the intervention. Findings suggested that teachers' induced achievement motivational climates can influence students' perceptions and prompt PBS states consistent with the motivational atmosphere.

2014-07-01

This study aimed to analyze the level of knowledge concerning emergency contraception among adolescents in public and private high schools. This was a cross-sectional study with 705 students 15 to 19 years of age enrolled in public and private high schools in a municipality in São Paulo State, Brazil. The authors used stratified probabilistic sampling by type of school and systematic sampling by class. Sexual initiation and use of emergency contraception were reported by 24.9% of private school students and 32% of public school students. The mean score on knowledge was 3.87 (SD = 2.12) in public schools and 5.14 (SD = 2.00) in private schools. Multiple linear regression analysis showed that higher scores on knowledge concerning emergency contraception were associated with: enrollment in private schools, female gender, older adolescents, sexual initiation, previous use of emergency contraception, and knowing someone who had used the method. The study concludes that few adolescents are properly informed about the method and that many harbor persistent misconceptions.

OBJECTIVE: To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group. METHODS: Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity. RESULTS: Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2). CONCLUSIONS: The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group. PMID:25119751

To investigate the prevalence of suspected myopia among students and to examine the relationship between time spent on physical exercise, sleep, homework and suspected myopia. A total of 8 030 primary and secondary school students from 4(th) to 12(th) grades were selected from the National Student Constitution and Health Survey (NSCHS) in Anhui province in 2014. Time spent on exercise, sleep and homework per day were collected using a self-administrated questionnaire. Visual acuity was examined using the Standard Logarithmic Visual Acuity Chart. The overall prevalence of suspected myopia was 69.03%. Prevalence rates of suspected myopia appeared higher in girls, in urban students, with the highest in the 16 to 18 year-old groups. RESULTS from the multiple logistic regression analysis showed that the amount of time spent on physical exercise, sleep and homework per day were all significantly associated with suspected myopia. Suspected myopia was associated with longer time on physical exercise among students aged 8 to 12 years (OR=0.80, 95%CI: 0.64-0.99), and longer sleep time among students in the age groups of 13 to 15 years and 16 to 18 years (OR=0.73, 95% CI: 0.56-0.94;OR=0.38, 95% CI: 0.21-0.68, respectively). Longer time spent on homework significantly increased the risk of suspected myopia among students in the age groups of 8 to 12 years and 13 to 15 years (OR=1.41, 95%CI: 1.11-1.79; OR=1.74, 95% CI: 1.36-2.23, respectively). Suspected myopia appeared common among students. Comprehensive intervention programs focusing on sufficient physical exercise and sleep but less homework might help to prevent myopia among students at different ages.

2013-12-01

To estimate the prevalence of myopia based on reduced unaided visual acuity (VA) in Chinese school children over the past 20 years. Guangzhou school health authorities have measured VA on Grade 1-12 students from 1988 to 2007 annually, using a LogMAR tumbling E chart. VA is reported as Snellen categories: normal (VA ≥ 6/6), mildly reduced (6/9 < VA <6/6), moderately reduced (6/18 < VA ≤ 6/9), and severely reduced VA (VA ≤ 6/18). In 1988, over 80% of children in Grade 1 (age 6 years) and about 30% in Grade 12 (age 17 years) had normal unaided VA. By 2007, this dropped to only 60% in Grade 1 and about 10% in Grade 12. Conversely, the prevalence of moderately and severely reduced unaided VA increased from 6.2% in Grade 1 and 62.5% in Grade 12 in 1988 to 14.5% in Grade 1 and 84.11% in Grade 12 in 2007. This rate was unchanged from 2003 to 2007 at both the Grade 1 and Grade 12 levels. In Guangzhou, the prevalence of reduced unaided VA has increased markedly in the past 20 years, but has stabilized in the past few years. This increase may result from environmental changes, such as increased schooling intensity and urbanization.

Objective Racial/ethnic differences in common carotid artery intima-media thickness (CIMT) and in risk factors associated with CIMT have been predominantly observed in middle-aged and older individuals. We aimed to characterize racial/ethnic differences CIMT and other cardiovascular risk factors in a healthy, young-adult population. Methods College students were recruited as part of a study to characterize determinants of atherogenesis. Students were eligible if they were lifetime non-smokers, lived in the United States since six months of age, and attended high school in the United States. Blood pressure, heart rate, height, and weight were measured, B-mode carotid ultrasound was performed, questionnaires were administered and a 12-hr fasting blood sample was collected. Associations between CIMT and other variables were assessed in 768 students aged 18 to 25 years using linear regression analysis. Results In models adjusted for common cardiovascular risk factors, sex exhibited the strongest influence on CIMT, with men having 15.4 µm larger CIMT compared to women (95%CI 6.6, 24.2). Race/ethnicity was also strongly associated with CIMT. African Americans had 17.3 µm greater CIMT (95% CI −0.3, 34.8) compared to non Hispanic Whites, whereas Asians and Hispanic Whites had 14.3 (95%CI −24.3, −4.4) and 15.4 (95%CI −26.2, −4.7) µm smaller CIMT, respectively. BMI and systolic blood pressure were positively associated with CIMT. Conclusion The risk factors associated with atherogenesis later in life are already present and observable in college-aged young adults, so targeted campaigns to reduce life-long cardiovascular disease burden should be initiated earlier in life to improve public health.

The current study explores whether theorized risk factors in Western countries can be used to predict school violence perpetration in an Asian cultural context. The study examines the associations between risk factors and school violence perpetration in Taiwan. Data were obtained from a nationally representative sample of 14,022 students from elementary to high school (Grades 4 to 12) across Taiwan. The analysis reported in this study focuses on only junior high school students (Grades 7 to 9, N = 3,058). The results of a regression analysis show that gender, age, direct victimization, witness victimization, alcohol use, smoking, anger traits, lack of impulse control, attitudes toward violence, poor quality of student-teacher relationships, and involvement with at-risk peers were significantly associated with school violence in Taiwan. The overall results suggest strong similarities in risk factors found in the West and school violence in Taiwan. They therefore point toward using similar strategies developed in the West to enhance students' positive experiences in their personal, family, and school lives to decrease school violence.

Adolescents in southern African high schools are a key population for HIV prevention interventions. We report on the prevalence of HIV, HSV-2 and pregnancy as indicators of high-risk sexual behaviour among high school students in rural KwaZulu-Natal. Bio-behavioural cross-sectional survey. Students completed a self-administered structured, standardised demographic and sexual behavioural questionnaire. Dried blood spot specimens were collected for HIV and HSV-2 testing. Urine specimens were used for pregnancy testing in female students. A total of 2675 (1423 females, 1252 males) consenting students were enrolled from 14 high schools between September and November 2010. The median age of students was 16 years (IQR 15-18). HIV prevalence was 1.4% (95% CI 0.9 to 1.9) in males and 6.4% (95% CI 4.6 to 8.3) in females (p<0.001). HSV-2 prevalence was 2.6% (95% CI 1.6 to 3.7) in males and 10.7% (95% CI 8.8 to 12.6) in females (p<0.001). Pregnancy prevalence was 3.6% (95% CI 2.6 to 4.5). Risk factors for prevalent HIV infection in female students included being over 18 years of age (adjusted OR (aOR)=2.67, 95% CI 1.67 to 4.27; p<0.001), prevalent HSV-2 infection (aOR=4.35, 95% CI 2.61 to 7.24; p<0.001), previous pregnancy (aOR=1.66, 95% CI 1.10 to 2.51; p=0.016) and experience of two or more deaths in the household in the previous year (aOR=1.97, 95% CI 1.13 to 3.44; p=0.016). The high prevalence of HIV, HSV-2 and pregnancy underscore the need for school-based sexual and reproductive health services, and provide further impetus for the inclusion of adolescents in behavioural and biomedical trials with HIV incidence endpoints.

Number Sense and Mathematics: Which, When and How?

PubMed Central

2017-01-01

Individual differences in number sense correlate with mathematical ability and performance, although the presence and strength of this relationship differs across studies. Inconsistencies in the literature may stem from heterogeneity of number sense and mathematical ability constructs. Sample characteristics may also play a role as changes in the relationship between number sense and mathematics may differ across development and cultural contexts. In this study, 4,984 16-year-old students were assessed on estimation ability, one aspect of number sense. Estimation was measured using 2 different tasks: number line and dot-comparison. Using cognitive and achievement data previously collected from these students at ages 7, 9, 10, 12, and 14, the study explored for which of the measures and when in development these links are observed, and how strong these links are and how much these links are moderated by other cognitive abilities. The 2 number sense measures correlated modestly with each other (r = .22), but moderately with mathematics at age 16. Both measures were also associated with earlier mathematics; but this association was uneven across development and was moderated by other cognitive abilities. PMID:28758784

Uncorrected refractive error and associated factors among primary school children in Debre Markos District, Northwest Ethiopia

PubMed Central

2014-01-01

Background Uncorrected Refractive Error is one of the leading cause amblyopia that exposes children to poor school performance. It refrain them from productive working lives resulting in severe economic and social loses in their latter adulthood lives. The objective of the study was to assess the prevalence of uncorrected refractive error and its associated factors among school children in Debre Markos District. Method A cross section study design was employed. Four hundred thirty two students were randomly selected using a multistage stratified sampling technique. The data were collected by trained ophthalmic nurses through interview, structured questionnaires and physical examinations. Snellens visual acuity measurement chart was used to identify the visual acuity of students. Students with visual acuity less than 6/12 had undergone further examination using auto refractor and cross-checked using spherical and cylindrical lenses. The data were entered into epi data statistical software version 3.1 and analyzed by SPSS version 20. The statistical significance was set at α ≤ 0.05. Descriptive, bivariate and multivariate analyses were done using odds ratios with 95% confidence interval. Result Out of 432 students selected for the study, 420 (97.2%) were in the age group 7–15 years. The mean age was 12 ± 2.1SD. Overall prevalence of refractive error was 43 (10.2%). Myopia was found among the most dominant 5.47% followed by astigmatism 1.9% and hyperopia 1.4% in both sexes. Female sex (AOR: 3.96, 95% CI: 1.55-10.09), higher grade level (AOR: 4.82, 95% CI: 1.98-11.47) and using computers regularly (AOR: 4.53, 95% CI: 1.58-12.96) were significantly associated with refractive error. Conclusion The burden of uncorrected refractive errors is high among primary schools children. Myopia was common in both sexes. The potential risk factors were sex, regular use of computers and higher grade level of students. Hence, school health programs should work on health information dissemination and eye health care services provision. PMID:25070579

ABSTRACT OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA. These results may assist in the preparation of preventive programs and policies on health and a better understanding of the factors associated with asthma in this age group. PMID:26910542

Our study is the first to describe the prevalence and correlates (demographics, body mass index [BMI], sedentary behaviors, and physical activity) of high school youth who report active videogame playing (active gaming) in a U.S. representative sample. The National Youth Physical Activity and Nutrition Study of 2010 provided data for this study. Active gaming was assessed as the number of days in the 7 days prior to the survey that students in grades 9-12 (14-18 years of age) reported participating in active videogames (e.g., "Wii™ Fit" [Nintendo, Kyoto, Japan], "Dance Dance Revolution" [Konami, Osaka, Japan]). Students reporting ≥1 days were classified as active gamers. Logistic regression was used to examine the association among active gaming and demographic characteristics, BMI, sedentary behaviors, and physical activity. Among 9125 U.S. high school students in grades 9-12 surveyed, 39.9 percent (95 percent confidence interval=37.9 percent, 42.0 percent) reported active gaming. Adjusting for covariates, the following characteristics were positively associated (P<0.05) with active gaming: being in 9th and 10th grades compared with being in 12th grade; being of black, non-Hispanic race/ethnicity; being overweight or obese; watching DVDs >0 hours/day; watching TV >0 hours/day; and meeting guidelines for aerobic and muscle-strengthening physical activity. Four out of 10 U.S. high school students report participating in active gaming. Active gamers tend to spend more time watching DVDs or TV, meet guidelines for physical activity, and/or be overweight or obese compared with nonactive gamers. These findings may serve to provide a baseline to track active gaming in U.S. youth and inform interventions that target sedentary behaviors and/or physical activity.

To study the effect of myopia and spectacle wear on bicycle-related injuries in rural Chinese students. Myopia is common among Chinese students but few studies have examined its effect on daily activities. Data on visual acuity, refractive error, current spectacle wear, and history of bicycle use and accidents during the past 3 years were sought from 1891 students undergoing eye examinations in rural Guangdong province. Refractive and accident data were available for 1539 participants (81.3%), among whom the mean age was 14.6 years, 52.5% were girls, 26.8% wore glasses, and 12.9% had myopia of less than -4 diopters in both eyes. More than 90% relied on bicycles to get to school daily. A total of 2931 accidents were reported by 423 participants, with 68 requiring medical attention. Male sex (odds ratio, 1.55; P < .001) and spectacle wear (odds ratio, 1.38; P = .04) were associated with a higher risk of accident, but habitual visual acuity and myopia were unassociated with the crash risk, after adjusting for age, sex, time spent riding, and risky riding behaviors. These results may be consistent with data on motor vehicle accidents implicating peripheral vision (potentially compromised by spectacle wear) more strongly than central visual acuity in mediating crash risk.

The current cross-national study investigates the potential buffering role of socio-motivational relationships for the association of achievement drive (AD) and test anxiety (TX) in secondary school students from Canada and Germany. One thousand and eighty-eight students (54% girls, M age = 13.71, SD = 0.53, age span 12-15 years) from the state of Brandenburg and 389 students from Quebéc (55.9% girls, M age = 13.43, SD = 0.82, age span 12-16 years) were asked about their socio-motivational relationships with their teachers and peers, their drive for achievement, and TX. Multigroup latent moderated structural equations were conducted to test for the moderator role of socio-motivational relationships that would buffer feelings of TX related to the drive for achievement. The analyses revealed the two-sided role socio-motivational relationships can have for students with different levels of AD; intensifying or mitigating feelings of TX. Thereby, the results of this study extend the buffering hypothesis by Cohen and Wills (1985). Cross-national differences between Canada and Germany were found concerning the studied moderators on the association of AD and TX: While for German students teacher-student relationships acted as moderator, for Canadian students student-student relationships and teachers acting as positive motivators displayed a moderator role.

To assess whether timing of introduction of fish and the amount of fish consumption in infancy were associated with asthmalike symptoms at preschool age. This study was embedded in the Generation R study (a population-based birth cohort in Rotterdam, Netherlands). At the age of 12 and 14 months, timing of introduction of fish into the infant's diet was assessed. The amount of fish consumption at 14 months was assessed by a semiquantitative food frequency questionnaire. Presence of asthmalike symptoms in the past year was assessed at the child's age of 36 and 48 months. Relative to no introduction in the first year of life, introduction between age 6 and 12 months was significantly associated with a lower risk of wheezing at 48 months (odds ratio [OR]: 0.64; 95% CI: 0.43-0.94). When compared with introduction between 6 and 12 months, no introduction in the first year and introduction between 0 and 6 months were associated with an increased risk of wheezing at 48 months (OR: 1.57; 95% CI: 1.07-2.31 and OR: 1.53; 95% CI: 1.07-2.19, respectively). The amount of fish at age 14 months was not associated with asthmalike symptoms (P > .15). Introduction of fish between 6 and 12 months but not fish consumption afterward is associated with a lower prevalence of wheezing. A window of exposure between the age of 6 and 12 months might exist in which fish might be associated with a reduced risk of asthma.

To examine one component of the instrument-based background in the University of California Keck Carbon Cycle AMS spectrometer, we have obtained measurements on a set of natural diamonds pressed into sample holders. Natural diamond samples (N = 14) from different sources within rock formations with geological ages greatly in excess of 100 Ma yielded a range of currents (∼110-250 μA 12C- where filamentous graphite typically yields ∼150 μA 12C-) and apparent 14C ages (64.9 ± 0.4 ka BP [0.00031 ± 0.00002 fm] to 80.0 ± 1.1 ka BP [0.00005 ± 0.00001 fm]). Six fragments cut from a single diamond exhibited essentially identical 14C values - 69.3 ± 0.5 ka-70.6 ± 0.5 ka BP. The oldest 14C age equivalents were measured on natural diamonds which exhibited the highest current yields.

Visual impairment is a significant loss of vision. It has an impact on the prosperity of different countries. It has been difficult to plan preventive measures against visual impairment due to the scarcity of data about the extent of the problem. The study was aimed at assessing the prevalence and identifying factors associated with visual impairment among school-age children in Ethiopia. A cross-sectional study design was used in four randomly selected schools found in Addis Ababa from May 15 to June 14, 2016. A total of 804 school-age students were selected using the simple random sampling method. Bivariable logistic regression and multivariable logistic regression were conducted. A p -value <0.05 was taken as a significant association. A total of 718 students participated in the study, obtaining a response rate of 89.3%. In all, 7.24% of school-age children were visually impaired, of whom 3.9% had low vision and 3.34% had severe visual impairment. Factors associated with visual impairment were being female (adjusted odds ratio [AOR], 2.28; 95% confidence interval [CI], 1.06-3.50), being in the age group of 10-13 years (AOR, 2.94; 95% CI, 1.36-6.22), being in the age group of 14-18 years (AOR, 4.06; 95% CI, 2.17-11.95), being a private school student (AOR, 2.61; 95% CI, 1.81-4.41), watching television for 2-4 hours/day (AOR, 3.56; 95% CI, 1.37-7.34), watching television at <1 m (AOR, 7.65; 95% CI, 2.59-34.61), watching television at 1-2 m (AOR, 6.89; 95% CI, 1.74-25.27), mobile exposure for 2-4 hours/day (AOR, 2.61; 95% CI, 1.35-4.58), mobile exposure for >4 hours/day (AOR, 3.05; 95% CI, 1.41-9.18), medical visit while experiencing symptoms (AOR, 11.32; 95% CI, 1.80-82.25) and no medical visit experience (AOR, 3.84; 95% CI, 0.46-31.76). The majority of the visually impaired school-age children had low vision. Sex, age, school type, television exposure duration, the distance of television exposure, mobile exposure and medical visit were factors associated with visual impairment. Increasing community awareness about early detection of visual impairment and providing affordable eye health service may decrease the prevalence of visual impairment.

To examine how adolescents' inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. DESIGN, SETTINGS: A prospective, longitudinal study: baseline at ages 11-12, follow-up at age 14. A population-based sample of Finnish twins, born 1983-1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Twin individuals (n = 4552), aged 11-12 at baseline and 14 (average 14.04 years) at follow-up. At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Inventory (MPNI, Teacher Form) and parental smoking with individual questionnaires completed by each twins' parents; at the age 14 follow-up, adolescent smoking was assessed with a self-report questionnaire. At age 14, 57% reported never having smoked, 34% had experimented with cigarettes and 9% were current smokers. Inattentiveness and parental smoking additively predicted both experimental and current smoking in adolescence. The effects were independent of each other. The risk related to inattentiveness itself is high, but in combination with the effects of parental smoking, the probability of current smoking can rise as high as 38%, compared with 5% without these two risk factors. For prevention purposes, parental commitment to non-smoking should be emphasized.

Systematic review and meta-analysis of published prevalence of scoliosis among primary and middle school students in Mainland China. To evaluate the prevalence of scoliosis among primary and middle school students in Mainland China. There is substantial uncertainty regarding the prevalence of scoliosis in Mainland China among the primary and middle school students. We conducted a systematic review aiming to describe the prevalence of scoliosis in Mainland China. We systematically reviewed the published epidemiological studies or reports on the prevalence of scoliosis in Chinese cities. Scopus, PubMed, WanFang Database, CNKI, China National Science and Technology Digital Library, and WeiPu Database were searched for studies reporting a prevalence estimate for scoliosis in primary and middle school students. Meta-analyses were performed to estimate the pooled prevalence of scoliosis by STATA 12.0. Subgroup analyses were conducted according to the sex, age, and geographical area. A total of 38 articles, including 697,043 patients, were eligible for inclusion in this review. Meta-analyses revealed the prevalence of scoliosis to be 1.02% (95% [confidence interval] CI, 0.85-1.18) among the primary and middle school students in Mainland China. The female to male ratio was 1.54 (95% CI, 1.35-1.74; P < 0.001). According to the subgroup analysis by different ages, the prevalence of scoliosis increased from 0.73% (95% CI, 0.55-0.90) to 1.14% (95% CI, 0.86-1.42). Meta-analyses showed that the prevalence of scoliosis in Mainland China was 1.02% among the primary and middle school students. The prevalence of scoliosis in females was higher than in males and the ratio was 1.54. As they grew older, the prevalence of scoliosis increased in the students.

The prevalence of childhood and adolescent obesity is increasing, with negative medical and psychosocial consequences. This study examines the association between weight status and nutrient intake, sport and leisure habits of middle school students in Bologna (Italy). Anthropometric data (height, weight) of 598 subjects (321 males and 277 females) 11-14 years old were collected. Questionnaires on nutrient intake, sport and leisure behaviour were administered. Protein, carbohydrate and total fat intakes of the adolescents were higher than the recommended ranges in all age groups and in both sexes. The proportion of energy from protein and total fat was higher than recommended, but the percentage from carbohydrate was lower. A significant proportion of the adolescents had a cholesterol intake above the Italian RDA and lower than recommended intakes for micronutrients. The prevalence of overweight and obesity is higher in males than in females at all ages (overweight: 35.2 vs 31.6 at 11 yrs.; 27.5 vs 20.2 at 12 yrs.; 18.6 vs 17.8 at 13 yrs.; 18.7 vs 10.9 at 14 yrs.; obesity: 5.5 vs 3.2 at 12 yrs.; 3.9 vs 1.1 at 13 yrs.; 5.3 vs 3.6 at 14 yrs.), except in subjects 11 years old (obesity: 7.4 vs 10.5). The overweight and obese adolescents consumed less carbohydrates and less fibre than their normal weight and underweight counterparts. The results of the present study indicate an unbalanced diet of the Bologna adolescents, which could damage their health and quality of life.

Proximal obstruction is reported to be the most common cause of ventriculoperitoneal (VP) shunt failure, suggesting that imperfect ventricular catheter placement and inadequate valve mechanisms are major causes. This study retrospectively examined patterns of shunt failure in 128 consecutive patients with symptoms of shunt malfunction over a 2-year period. Factors analyzed included site of failure, time from shunt placement or last revision to failure, age of patient at time of failure, infections, and primary etiology of the hydrocephalus. One hundred of these patients required revisions; 14 revisions were due to infections. In this series there was a higher incidence of distal (43%) than of proximal (35%) failure. The difference was not statistically significant when the overall series was considered; however, when factoring time to failure as a variable, marked differences were noted regardless of the underlying cause of hydrocephalus or the age of the patient. Of the 49 patients needing a shunt revision or replacement within 2 years of the previous operation, 50% had proximal malfunction, 14% distal, and 10% had malfunctions attributable directly to the valve itself. Also, 12 of the 14 infections occurred during this time interval. In sharp contrast, of the 51 patients having shunt failure from 2 to more than 12 years after the previous procedure, 72% had distal malfunction, 21% proximal, and only 6% had a faulty valve or infection. This difference between time to failure for proximal versus distal failures was statistically significant (P < 0.00001 for both Student's t-test and non-parametric Mann-Whitney U-test).(ABSTRACT TRUNCATED AT 250 WORDS)

2015-09-01

The purpose of the present article is to compare the individual, peer, family, and school risk and protective factors for both traditional and cyber-bullying victimization. This article draws on data from 673 students from Victoria, Australia, to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber-bullying victimization in Grade 9 (aged 14-15 years). Participants completed a modified version of the Communities That Care youth survey. There were few similarities and important differences in the predictors of traditional and cyber-bullying victimization. For Grade 9 cyber-bullying victimization, in the fully adjusted model, having been a victim of traditional bullying in Grade 7 and emotional control in Grade 7 were predictors. For Grade 9 traditional bullying victimization, predictors were Grade 7 traditional bullying victimization, association with antisocial peers, and family conflict, with family attachment and emotional control marginally statistically significant. The use of evidence-based bullying prevention programs is supported to reduce experiences of both traditional and cyber-bullying victimization, as is the implementation of programs to assist students to regulate their emotions effectively. In addition, traditional bullying victimization may be reduced by addressing association with antisocial friends, family conflict, and bonding to families. © The Author(s) 2014.

Competence skills help deter smoking among inner city adolescents.

To test whether higher levels of general competence are linked to more frequent use of refusal assertiveness that is in turn related to less subsequent smoking among inner city adolescents. Longitudinal study conducted during three year middle school or junior high school period. A sample of 1459 students attending 22 middle (ages 11-14 years) and junior high (ages 12-15 years) schools in New York City participated. Students completed surveys at baseline, one year follow up, and two year follow up. The students self reported smoking, decision making skills, personal efficacy, and refusal assertiveness. Teams of three to five data collectors administered the questionnaire following a standardised protocol. These data were collected in school during a regular 40 minute class period. Based on the tested structural equation model, decision making and personal efficacy (that is, general competence) predicted higher refusal assertiveness and this greater assertiveness predicted less smoking at the two year follow up. The tested model had a good fit and was parsimonious and consistent with theory. Adolescent smoking prevention programmes often teach refusal skills in order to help youth resist peer pressure to smoke. The present findings suggest that teaching general competence skills as well may help to reduce smoking because youth with better personal efficacy and decision making skills are better able to implement smoking refusal strategies.

Cyberbullying perpetration (using communication technology to engage in bullying) is a recent phenomenon that has generated much concern. There are few prospective longitudinal studies of cyberbullying. The current article examines the individual, peer, family, and school risk factors for both cyber and traditional bullying (the latter is bullying that does not use technology) in adolescents. This article draws on a rich data set from the International Youth Development Study, a longitudinal study of students in Victoria, Australia and Washington State, United States, which began in 2002. In this article, data from almost 700 Victorian students recruited in grade 5 are analyzed to examine grade 7 (aged 12-13 years) predictors of traditional and cyberbullying perpetration in grade 9 (aged 14-15 years). Fifteen per cent of students engaged in cyberbullying, 21% in traditional bullying, and 7% in both. There are similarities and important differences in the predictors of cyber and traditional bullying. In the fully adjusted model, only prior engagement in relational aggression (a covert form of bullying, such as spreading rumors about another student) predicted cyberbullying perpetration. For traditional bullying, previous relational aggression was also predictive, as was having been a victim and perpetrator of traditional bullying, family conflict, and academic failure. The use of evidence-based bullying prevention programs is supported to reduce experiences of all forms of bullying perpetration (cyber, traditional, and relational aggression). In addition, for traditional bullying perpetration, addressing family conflict and student academic support are also important. Copyright © 2012 Society for Adolescent Health and Medicine.

To compare rates of early addictive behaviours in a clinic sample of youth with childhood attention-deficit/hyperactivity disorder (ADHD) with those in community populations. We surveyed 142 adolescents (14.1 ± 1.14 years), diagnosed with ADHD before age 12, about early substance use and problem gambling using questions from two cross-sectional population studies: the Canadian National Longitudinal Survey of Children and Youth, Ontario subsample, (N=1,317; 10-15 years) and the Ontario Student Drug Use and Health Survey (N=9,288; 12-18 years). The ADHD sample reported using cigarettes, 17.8% (95% CI 12.1-25.5), alcohol, 27.1% (20.1-35.5), cannabis, 14.2% (8.9-21.7), at a similar or lower rate than the NLSCY (cigarettes, 28.3% (25.8-30.9), alcohol, 28.6% (26.0-31.3), cannabis, 16.5% (14.0-19.4), and OSDUHS samples (cigarettes, 21.9% (20.2-23.7), alcohol, 58.6% (56.0-61.2), cannabis, 26.0% (23.9-28.2). With regards to gambling, there is a non-significant trend for ADHD youth to report gambling more frequently than the provincial average, 7.9% (3.3-17.9) vs. 4.3% (2.9-6.3). Our findings support the emerging literature that youth diagnosed with ADHD in childhood may not be at greater risk for onset of substance use in early adolescence. The study identified two areas that warrant further investigation in this population; the possible increased risk for substance use among females and a trend toward early onset of gambling behaviours.

Background: This paper presents the methodology and early findings of the fifth survey of a school-based surveillance program in Iran. Methods: This nationwide study was conducted in 2015 as the fifth survey of a surveillance program entitled “Childhood and Adolescence Surveillance and PreventIon of Adult Non- communicable disease” (CASPIAN-V) study. The protocol was mainly based on the World Health Organization-Global School student Health Survey. We studied 14400 students, aged 7-18 years, and their parents living in 30 provinces in Iran. Fasting blood was obtained from a sub-sample of 4200 randomly selected students. Results: The participation rate for the whole study and for blood sampling were 99% and 91.5%, respectively. The mean (SD) age of participants was 12.3 (3.2) years, consisting of 49.4% girls and 71.4% urban residents. Overall, 16.1% were underweight (17.4% of boys and 14.8% of girls), and 20.8% had excess weight consisting of 9.4% (8.7% of boys and 10.2% of girls) of overweight and 11.4% (12.5% of boys and 10.3% of girls) of obesity. Abdominal obesity was documented in 21.1% of students (21.6% of boys and 20.5% of girls). Low HDL-C was the most prevalent abnormality of the lipid profile (29.5%) followed by high serum triglycerides (27.7%). Of students, 59.9% consumed whole wheat bread; and 57% reported that they never or rarely added salt to table. The reported daily consumption of fresh fruits, vegetables, and milk was about 60%, 32% and 40%, respectively. 13.7% of participants had at least 30-min daily leisure-time physical activity. Conclusions: The current findings provide an overview of the current health status and lifestyle habits of children and adolescents. This surveillance program would help planning preventive programs at individual and community levels. PMID:28217266

2011-06-01

The objective of this study was to explore whether the time at which sex education was provided had any impact on reported cases of unintended pregnancies. A cross-sectional survey of secondary school students and their teachers was conducted using self-administered questionnaires. The participants were 1,234 students aged 14-17 years and 46 teachers in 5 secondary schools in South Eastern Nigeria. The outcome measures were reported pregnancies within the last 3 years by type of school and class level; class level at the time of receiving sex education at school; and age at the time of receiving sex education at home. In all schools, sex education was provided at all the junior and senior secondary school levels (JSS and SSS, respectively). Overall, reported cases of unintended pregnancies were highest among the junior students. In the private schools, four in ten teachers reported pregnancies among JSS 3 students. Almost four in ten teachers in public schools reported pregnancies among JSS 2 students. Of all the students, about three in ten reported pregnancies among JSS 2 and 3 students respectively. At home, sex education was provided at the mean age of 16 years (SD ± 2.2). All participants cited financial need and marital promise as major predisposing factors. About four in ten students did not use contraceptives during their first sexual experience. This study highlights the need to introduce sex education much earlier, possibly before the JSS levels. At home, sex education may have greater impact if provided before the age of 14 years. Efforts should be made to address the factors predisposing to teenage pregnancy.

To describe the self-reported mental health of New Zealand secondary school students in 2012 and to investigate changes between 2007 and 2012. Nationally representative health and wellbeing surveys of students were completed in 2007 (n=9107) and 2012 (n=8500). Logistic regressions were used to examine the associations between mental health and changes over time. Prevalence data and adjusted odds ratios are presented. In 2012, approximately three-quarters (76.2%, 95% CI 74.8-77.5) of students reported good overall wellbeing. By contrast (also in 2012), some students reported self-harming (24.0%, 95% CI 22.7-25.4), depressive symptoms (12.8%, 95% CI 11.6-13.9), 2 weeks of low mood (31%, 95% CI 29.7-32.5), suicidal ideation (15.7%, 95% 14.5-17.0), and suicide attempts (4.5%, 95% CI 3.8-5.2). Between 2007 and 2012, there appeared to be slight increases in the proportions of students reporting an episode of low mood (OR 1.14, 95% CI 1.06-1.23, p=0.0009), depressive symptoms (OR 1.16, 95% CI 1.03-1.30, p=0.011), and using the Strengths and Difficulties Questionnaire - emotional symptoms (OR 1.38, 95% CI 1.23-1.54, p<0.0001), hyperactivity (OR 1.16, 95% CI 1.05-1.29, p=0.0051), and peer problems (OR 1.27, 95% CI 1.09-1.49, p=0.0022). The proportion of students aged 16 years or older reporting self-harm increased slightly between surveys, but there was little change for students aged 15 years or less (OR 1.29, 95% CI 1.15-1.44 and OR 1.10, 95% 0.98-1.23, respectively, p=0.0078). There were no changes in reported suicidal ideation and suicide attempts between 2007 and 2012. However, there has been an improvement in self-reported conduct problems since 2007 (OR 0.78, 95% CI 0.70-0.87, p<0.0001). The findings suggest a slight decline in aspects of self-reported mental health amongst New Zealand secondary school students between 2007 and 2012. There is a need for ongoing monitoring and for evidence-based, accessible interventions that prevent mental ill health and promote psychological wellbeing.

To determine the sexual behavioral pattern, consequences, and adopted solutions among senior secondary schools students in Ojo military barracks, Lagos. This was a cross-sectional study of 400 senior secondary schools students in Ojo military barracks, Lagos, selected using a multistage sampling technique. Data was collected using pre-tested, self-administered semi-structured questionnaires. Data was analysed using statistical package for social sciences version 17. Tests of statistical significance were carried out using χ2-test, and a p-value of <0.05 was considered significant. The majority of them 391 (97.8%), were in the age group (10-19 years) while the mean age was 15±2.4 for males and 15±2.2 for females, respectively. One hundred and fifty four (38.5%) of the respondents have had penetrative sexual intercourse and were influenced mainly by peer pressure (p=0.0000). Their age at first sexual intercourse ranged between 10-19 years. Ten (6.5%) of the respondents (all males) had their sexual debut with a commercial sex worker. More girls 41 (56.2%) than boys 12 (14.8%), were forced into sexual intercourse (p=0.0000). Over half of the sexually active respondents had at least two sexual partners for either sex. Findings from this study have shown that young people living in the barracks indulged in sexual activity at very early ages and engaged in risky sexual behavior. We therefore recommend an improved multi-sectoral approach in reproductive health and sexually transmitted infections including HIV/AIDS education.

To investigate the impact of emotional maltreatment on self-esteem among adolescents, and to see if gender makes a difference in this context. The cross-sectional study was conducted from January to April 2014, and comprised adolescents in the age range of 14 to 18 years who were selected using purposive sampling from various government and private schools and colleges of Sargodha, Punjab. The questionnaire on seven dimensions of emotional maltreatment at home and Rosenberg self-esteem scale were used. There were 400 subjects; 200(50%) boys and as many girls. The overall mean age was 16.14±1.36 years (range: 14-18 years). Correlation coefficient indicated significant negative relationship between emotional maltreatment and self-esteem (degrading r= -0.33, p<0.01; exploitation r= -0.30, p< 0.01; isolating r=-0.36, p<0.01; ignoring r= -0.32, p<0.01; rejecting r=-0.43, p< 0.01; and terrorizing r= -0.35, p<0.01) among students. Emotional maltreatment strongly predicted negative self-esteem (isolating?= -0.12, p<0.05; and rejecting ?= -0.30, p< 0.001) among adolescents. Findings indicated significant gender differences in degrading component of emotional maltreatment and self-esteem. Emotional maltreatment strongly predicted negative self-esteem among adolescents. Gender was a significant factor in the domain of degrading.

Attitudes of medical students to induced abortion.

Unsafe abortion causes 13% of maternal deaths worldwide. Safe abortion can only be offered under conditions where legislation has been passed for legal termination of unwanted pregnancy. Where such legislation exists, accessibility of safe abortion depends on the attitudes of doctors and other healthcare workers to induced abortion. Medical students as future doctors may have attitudes to abortion that will affect the provision of safe abortion. Little is known about the attitudes of South African medical students to abortion. To assess sexual practices and attitudes of medical students to induced abortion and to determine some of the factors that may influence these attitudes. A cross-sectional analytic study involving the self-administration of an anonymous questionnaire. The questionnaire was administered to medical students at a small, but growing, medical school situated in rural South Africa. Demographic data, sexual practices and attitudes to induced abortion. Two hundred and forty seven out of 300 (82.3%) medical students responded. Their mean age was 21.81 +/- 3.36 (SD) years, and 78.8% were Christians, 17.1% Hindus and 2.6% Muslims. Although 95% of the respondents were single, 68.6% were already sexually experienced, and their mean age at coitarche was 17.24+/-3.14 (SD) years. Although overall 61.2% of the respondents felt abortion is murder either at conception or later, the majority (87.2%) would perform or refer a woman for abortion under certain circumstances. These circumstances, in descending order of frequency, include: threat to mother's life (74.1%), in case of rape (62.3%), the baby is severely malformed (59.5%), threat to mother's mental health (53.8%) and parental incompetence (21.0%). Only 12.5% of respondents would perform or refer for abortion on demand, 12.8% would neither perform nor refer for abortion under any circumstances. Religious affiliation and service attendance significantly influenced some of these attitudes and beliefs. Although many of the medical students personally felt abortion is murder, the majority are likely to perform or refer patients for abortion under certain circumstances; only about a tenth are likely to perform or refer patients for abortion on demand.

The Children's Automatic Thoughts Scale (CATS) is a 40-item self-report questionnaire designed to measure children's negative thoughts. This study examined the psychometric properties of the Chinese translation of the CATS. Participants included 1,993 students (average age = 14.73) from three schools in Mainland China. A subsample of the participants was retested after 4 weeks. Confirmatory factor analysis replicated the original structure with four first-order factors loading on a single higher-order factor. The convergent and divergent validity of the CATS were good. The CATS demonstrated high internal consistency and test-retest reliability. Boys scored higher on the CATS-hostility subscale, but there were no other gender differences. Older adolescents (15-18 years) reported higher scores than younger adolescents (12-14 years) on the total score and on the physical threat, social threat, and hostility subscales. The CATS proved to be a reliable and valid measure of automatic thoughts in Chinese adolescents.

Repeated and deliberate practice is crucial in surgical skills training, and virtual reality (VR) simulation can provide self-directed training of basic surgical skills to meet the individual needs of the trainee. Assessment of the learning curves of surgical procedures is pivotal in understanding skills acquisition and best-practice implementation and organization of training. To explore the learning curves of VR simulation training of mastoidectomy and the effects of different practice sequences with the aim of proposing the optimal organization of training. A prospective trial with a 2 × 2 design was conducted at an academic teaching hospital. Participants included 43 novice medical students. Of these, 21 students completed time-distributed practice from October 14 to November 29, 2013, and a separate group of 19 students completed massed practice on May 16, 17, or 18, 2014. Data analysis was performed from June 6, 2014, to March 3, 2015. Participants performed 12 repeated virtual mastoidectomies using a temporal bone surgical simulator in either a distributed (practice blocks spaced in time) or massed (all practice in 1 day) training program with randomization for simulator-integrated tutoring during the first 5 sessions. Performance was assessed using a modified Welling Scale for final product analysis by 2 blinded senior otologists. Compared with the 19 students in the massed practice group, the 21 students in the distributed practice group were older (mean age, 25.1 years), more often male (15 [62%]), and had slightly higher mean gaming frequency (2.3 on a 1-5 Likert scale). Learning curves were established and distributed practice was found to be superior to massed practice, reported as mean end score (95% CI) of 15.7 (14.4-17.0) in distributed practice vs. 13.0 (11.9-14.1) with massed practice (P = .002). Simulator-integrated tutoring accelerated the initial performance, with mean score for tutored sessions of 14.6 (13.9-15.2) vs. 13.4 (12.8-14.0) for corresponding nontutored sessions (P < .01) but at the cost of a drop in performance once tutoring ceased. The performance drop was less with distributed practice, suggesting a protective effect when acquired skills were consolidated over time. The mean performance of the nontutored participants in the distributed practice group plateaued on a score of 16.0 (15.3-16.7) at approximately the ninth repetition, but the individual learning curves were highly variable. Novices can acquire basic mastoidectomy competencies with self-directed VR simulation training. Training should be organized with distributed practice, and simulator-integrated tutoring can be useful to accelerate the initial learning curve. Practice should be deliberate and toward a standard set level of proficiency that remains to be defined rather than toward the mean learning curve plateau.

Revisiting the Link Between Depression Symptoms and High School Dropout: Timing of Exposure Matters.

Recent reviews concluded that past depression symptoms are not independently associated with high school dropout, a conclusion that could induce schools with high dropout rates and limited resources to consider depression screening, prevention, and treatment as low-priority. Even if past symptoms are not associated with dropout, however, it is possible that recent symptoms are. The goal of this study was to examine this hypothesis. In 12 disadvantaged high schools in Montreal (Canada), all students at least 14 years of age were first screened between 2012 and 2015 (N screened  = 6,773). Students who dropped out of school afterward (according to school records) were then invited for interviews about their mental health in the past year. Also interviewed were matched controls with similar risk profiles but who remained in school, along with average not at-risk schoolmates (N interviewed  = 545). Interviews were conducted by trained graduate students. Almost one dropout out of four had clinically significant depressive symptoms in the 3 months before leaving school. Adolescents with recent symptoms had an odd of dropping out more than twice as high as their peers without such symptoms (adjusted odds ratio = 2.17; 95% confidence interval = 1.14-4.12). In line with previous findings, adolescents who had recovered from earlier symptoms were not particularly at risk. These findings suggest that to improve disadvantaged youths' educational outcomes, investments in comprehensive mental health services are needed in schools struggling with high dropout rates, the very places where adolescents with unmet mental health needs tend to concentrate.

2012-06-01

The aim of this study was to determine cognitive and motor status factors in female and male children aged 10-14, as well as developmental and/or integration functions according to gender. The study included 162 girls and 134 boys aged 10-14, divided into four groups: 84 girls aged 10-12 (mean age 11.26, SD 0.68), 84 boys aged 10-12 (mean age 11.41, SD 0.50), 78 girls aged 13-14 (mean age 13.52, SD 0.63) and 50 boys aged 13-14 (mean age 13.21, SD 0.53). The significance of quantitative differences between boys and girls in the overall system of variables was defined based on the results of canonic discriminant analysis of variance, and within each variable based on the results on univariate analysis of variance (ANOVA). In the younger age group (10-12 years), girls were superior to boys in a test assessing flexibility (Seated straddle stretch), whereas, compared to girls, boys had greater strength of the trunk (Crossed-arm sit-ups), greater explosive strength ofjump and sprint type (Standing broad jump and 20 m dash), and coordination (Obstacle course backwards and Steps laterally). In the older age group (13-14 years) differences in flexibility were even more prominent in favor of girls, whereas the differences in explosive strength increased in favor of boys, especially of the throwing type with better agility (Steps laterally), balance (Board balance) and greater static strength of arms and shoulders (Bent-arm hang). In order to determine qualitative differences between pubertal and prepubertal girls and boys, the matrix of variable inter-correlations was factorized by the procedure of principal components procedure, that were then transformed to promax solution. The results showed that cognitive functioning had a significant role in the motor efficacy of girls and boys aged 10 to 14. In the age group of 10-12 years, in females, cognitive functioning is related to the motor system which integrates the regulation of muscle tone with agility/coordination, whereas in males there is a relation between cognitive abilities and the regulator of speed of upper extremities movement frequency. In the age group of 13-14 years, in females, cognitive functioning is involved in forming the factors for regulation of coordination and the intensity of energy mobilization in lower extremities, and to some degree, in the factor for regulation of intensity of energy mobilization in upper extremities and strength of the trunk, whereas in males the integration of synergetic regulation of movement in terms of balance and agility in terms of speed of direction change is carried out with significant involvement of cognitive abilities.

Nutritional intake of various groups of Flemish vegetarians

PubMed Central

2011-01-01

Background The most recent national nutritional survey (2004) indicates that 1.2% of the Flemish population follows a vegetarian diet. Information on nutritional intake in vegetarians in this population is scarce. Objective The aim of the present study is to describe the nutritional intake and dietary adequacy of various groups of Flemish vegetarians. Materials and methods Nutritional intake was assessed in various vegetarian groups from different study designs: young children (aged 1 to 10 y; n = 27) (Group 1), adolescents and adults (aged 11 to 32 y; n = 50) (Group 2), college students (aged 18 to 24 y; n= 24) (Group 3), life-long vegetarians (aged 14 to 71 y; n = 36) (Group 4) and adults (aged 20 to 98; n= 106) (Group 5). Additionally, blood samples were collected and analysed in groups 3 and 4. Comparisons were made with standard references or with omnivores (Group 3). Results Nutritional intake was found to be close to the Belgian RDA. However, all groups showed a number of outliers with an intake of some nutrients above or below the RDAs. Blood biochemistry showed low cholesterol, iron and vitamin B12 levels in vegetarians when comparing respectively with omnivores pairs (Group 3) and with reference values (Group 4). Conclusions Data collected in Flemish vegetarians indicate that a vegetarian diet may be adequate. However, the outliers in all groups show that proper dietary planning is advisable.

The role of family relationship in adolescent use of emerging tobacco products, which have become increasingly popular, is unknown. We examined the associations of perceived family relationship quality with current use of poly-tobacco products including cigarettes, electronic cigarettes (e-cigarettes), waterpipe and smokeless tobacco in adolescents. Data from a representative sample of 42,250 US grade 7-12 equivalent students (mean ± SD age 14.6 ± 1.9 years; 51.3% boys) from 75 randomly selected secondary schools in Hong Kong (2012-13) were analysed. Logistic regressions yielded adjusted odds ratios (AORs) for current (past 30-day) use of cigarettes, e-cigarettes, waterpipe, smokeless tobacco and poly-tobacco (≥2 products) in relation to perceived family relationship quality, adjusted for age, sex, perceived family affluence, parental education, family structure, parental and sibling smoking and secondhand smoke exposure at home. Subgroup analyses were conducted to compare the associations in early (aged ≤14 years) versus late (>14) adolescents. The odds of current use increased with worse perceived family relationship quality with AORs (95% confidence interval) of up to 2.92 (2.32-3.68) for cigarettes, 7.28 (4.71-11.2) for e-cigarettes, 5.04 (3.44-7.40) for waterpipe, 8.09 (4.87-13.4) for smokeless tobacco and 5.25 (3.45-8.01) for poly-tobacco products use (all P for trend <.001). The associations for all tobacco use outcomes were stronger in early than late adolescents (all P for interaction <.001). Dose-response relationships were found between negatively perceived family relationship quality and current poly- and individual tobacco product use by Hong Kong Chinese secondary students. The associations were stronger for alternative tobacco products and in early adolescents. Copyright © 2018 Elsevier Ltd. All rights reserved.

To evaluate the efficacy and the rate of side effects of the pegylated aptamer pegaptanib in the treatment of patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) and a history of previous arterial thromboembolic events (ATEs). Twenty-three eyes of 23 patients with subfoveal CNV due to AMD and cerebrovascular accidents (n = 12) and myocardial infarction (n = 11) in the previous 6 months received intravitreal pegaptanib 0.3 mg according to a pro re nata regimen and were followed for 12 months. The paired Student t test was used to evaluate mean changes in best-corrected visual acuity (BCVA; primary outcome measure) and central foveal thickness (CFT). The mean patient age was 71.5 ± 4.6 years; there were 14 women and 9 men. The CNV was type 1, 2, and 3 in 18, 3, and 2 eyes, respectively. The mean BCVA improved from 0.67 ± 0.23 logMAR at baseline to 0.52 ± 0.31 logMAR at the end of 12-month follow-up (p = 0.044). Thirty-five percent of patients achieved ≥3 Early Treatment Diabetic Retinopathy Study lines improvement at 12 months. Mean CFT at baseline (381 ± 111 µm) decreased to 304 ± 82 µm at 12 months (p = 0.008). Patients received a mean of 4.3 ± 1.3 (range 3-7) injections. No systemic or ocular side effects occurred; no patient experienced further ATEs. Intravitreal pegaptanib can be considered a viable treatment option for patients with AMD-related CNV who are at high risk of ATEs.

To evaluate and compare the normative and subjective need for orthodontic treatment within different age groups in Turkey. One thousand and sixteen patients from seven different demographic regions of Turkey (Marmara, Black Sea, East Anatolia, Southeastern Anatolia, Mediterranean, Aegean, and Central Anatolia Region) (mean age ± SD: 12.80 ± 3.57 years) were randomly selected and divided into six age groups (7-8,9-10,11-12,13-14,15-16, and 17-18 year-olds) and categorized according to the dental health component (DHC) of the index for orthodontic treatment need (IOTN). Additionally, the patients were asked to indicate the photograph that was most similar to their own dentition from the 10-point scale of the aesthetic component of IOTN. The DHC of IOTN was not significantly different between the six age groups (P > 0.05). However, no/slight need (aesthetic component 1-4) for orthodontic treatment according to AC of IOTN was significantly higher in 13-14,15-16, and 17-18 age groups than 7-8, 9-10, and 11-12 age groups (P < 0.05). No sex differences were found in both DHC and aesthetic component of IOTN between age groups (P > 0.05). The normative need distribution was homogeneous within all the age groups according to DHC. However, the subjective need for orthodontic treatment was higher in the younger age groups.

Air pollutants have been associated with the exacerbation of respiratory diseases. They may intensify the inflammatory allergic response and airways reactivity to inhaled allergens. However, it is still not clear if air pollution contributes to the increased prevalence of asthma. To investigate if different levels of air pollution exposure can be related to differences in the prevalence of asthma. The International Study of Asthma and Allergies in Childhood (ISAAC) protocol was used to determine and compare the prevalence of asthma among schoolchildren in 2 cities of the metropolitan region of Rio de Janeiro, Brazil, Duque de Caxias (DC) and Seropédica (SR), which have different levels of atmospheric pollution. The research involved 4,064 students aged 13 to 14 years from 49 schools in DC and 1,129 from 17 schools in SR. Air pollution was evaluated by the concentration of inhalable particulate matter (PM10). ISAAC's written questionnaire was answered by 4,040 students aged 13 to 14 years in DC and 1,080 in SR. Between 1998 and 2000, the PM10 annual arithmetic mean was 124 microg/m3 in DC and 35 microg/m3 in SR (acceptable level is up to 50 microg/m3). The prevalence of wheezing ever was 35.1% in DC and 29.9% in SR (P = .001), and the prevalence of wheezing in the last 12 months was 19.0% in DC and 15.0% in SR (P = .002). In DC, 14.5% of the adolescents presented 1 to 3 crises of wheezing in the last year, whereas in SR only 11.0% presented 1 to 3 crises (P = .003). In this study, the prevalence of asthma in adolescents was directly related to atmospheric pollution.

Advanced Cardiovascular Life Support (ACLS) in life-threatening situations is perceived as a basic skill for dental professionals. However, medical emergency training in dental schools is often not standardized. The dental students' knowledge transfer to an ACLS setting thus remains questionable. The aim of the study was to evaluate dental pre-doctorate students' practical competence in ACLS in a standardized manner to enable the curriculum to be adapted to meet their particular needs. Thirty dental students (age 25.47 ± 1.81; 16 male/14 female) in their last year of dental studies were randomly assigned to 15 teams. Students' ability to successfully manage ACLS was assessed by a scenario-based approach (training module: Laerdal® ALS Skillmaster). Competence was assessed by means of (a) an observation chart, (b) video analysis and (c) training module analysis (Laerdal HeartSim®4000; Version 1.4). The evaluation was conducted by a trained anesthesiologist with regard to the 2010 guidelines of the European Resuscitation Council (ERC). Only five teams (33.3%) checked for all three vital functions (response, breathing and circulation). All teams initiated cardiopulmonary resuscitation (CPR). Only 54.12% of the compressions performed during CPR were sufficient. Four teams stopped the CPR after initiation. In total, 93% of the teams used the equipment for bag-valve-mask ventilation and 53.3% used the AED (Automated external defibrillator). ACLS training on a regular basis is necessary and, consistent with a close link between dentistry and medicine, should be a standardized part of the medical emergency curriculum for dental students with a specific focus on the deficiencies revealed in this study.

Binge Drinking Above and Below Twice the Adolescent Thresholds and Health-Risk Behaviors.

Underage drinking has been associated with health-risk behaviors: unintentional and unprotected sex; physical and sexual assault; suicide; homicide; traffic and other unintentional injuries; and overdoses. Five drinks consumed over 2 hours by adult males and 4 drinks by adult females typically produce blood alcohol levels (BALs) of ≥0.08%, which the National Institute on Alcohol Abuse and Alcoholism considers binge drinking. Being smaller, young adolescents can reach adult binge-drinking BALs of ≥0.08% with fewer drinks. Previous research indicates boys ages 9 to 13 would reach ≥0.08% with 3 drinks, 4 drinks at ages 14 to 15, and 5 drinks at ages ≥16. For girls, ≥0.08% is reached with ≥3 drinks at ages 9 to 17 and ≥4 drinks at ages ≥18. This study explores whether, among a national sample of high school students, adolescent binge drinking at ≥twice versus

The study evaluated the growth status and secular change in body size of indigenous Tarahumara children in northern Mexico. Heights and weights of Tarahumara children 6-14 years were measured in 1990 (n = 601) and 2007 (n = 583); the BMI was calculated. International criteria defined weight status while United States reference data defined stunting. Estimated secular gains in height from 1990 to 2007 were greatest in 6-7 year-old boys and declined with age to a small, non-significant secular decline in boys 12-14 years. Among girls secular gains in height were similar at 6-7 and 8-9 years, largest at 10-11 years and small and non-significant at 12-14 years. Secular gains in weight were similar among 6-7 and 8-9 year-old boys and girls, were greater in girls than in boys at 10-11 years and showed a small, non-significant secular decline in boys and girls 12-14 years. Secular change in the BMI paralleled those for weight. The prevalence of stunting declined from 1990 to 2007 in both sexes and all age groups except 12-14 year youth. Overweight was more prevalent in girls than boys in both years and increased from 4% to 7% in boys and 9% to 13% in girls. Obesity was not common among boys and girls in each age group and in both years. Stunting and overweight/obesity were not related in either 1990 or 2007. Positive secular changes in growth status have occurred in Tarahumara children 6-11 years in contrast to negligible changes among children 12-14 years. The results suggest recent improvements in health and nutrition sufficient to support a positive secular trend in younger children.

In adolescents aged 12-14, we measured attitudes to tobacco advertising. Our purpose is to understand the relation of these attitudes to tobacco use and identify the groups most influenced by the advertising. Survey of adolescents on Gran Canaria Island, Spain, about aspects of family, school, peers, tobacco consumption, and tobacco advertising. The subjects of the double-stratified cluster sample were 1910 students at the same grade level in 33 schools; 86.6% were 13 or 14 years old, and 51.2% were boys. We generated measures for attitudes to tobacco advertising from replies to seven questions with ordinal scales by an analysis of categorical principal components. To relate attitude to tobacco advertising and the profiles of these adolescents, we used multiple regression and logistic regression models. Attitudes to tobacco advertising are related to some home and school factors, but most significantly to tobacco and alcohol consumption, to amount of time at home without adults, and to peer influence. It is possible to draw up profiles of the students most vulnerable to tobacco advertising, and to cluster them in two groups, the "vitalists" and the "credulous." The effect of cigarette ads is different between these groups. This study can help to orientate smoking prevention.

It is now possible to create individual-specific genetic scores, called genome-wide polygenic scores (GPS). We used a GPS for years of education ( EduYears ) to predict reading performance assessed at UK National Curriculum Key Stages 1 (age 7), 2 (age 12) and 3 (age 14) and on reading tests administered at ages 7 and 12 in a UK sample of 5,825 unrelated individuals. EduYears GPS accounts for up to 5% of the variance in reading performance at age 14. GPS predictions remained significant after accounting for general cognitive ability and family socioeconomic status. Reading performance of children in the lowest and highest 12.5% of the EduYears GPS distribution differed by a mean growth in reading ability of approximately two school years. It seems certain that polygenic scores will be used to predict strengths and weaknesses in education.

School-based, free HPV vaccination for girls in the first year of secondary school was introduced in Flanders (Belgium) in 2010. Before that, non school-based, co-payment vaccination for girls aged 12-18 was in place. We compared vaccination coverage, age-specific coverage and socio-economic inequalities in coverage - 3 important parameters contributing to the effectiveness of the vaccination programs - under both vaccination systems. We used retrospective administrative data from different sources. Our sample consisted of all female members of the National Alliance of Christian Mutualities born in 1995, 1996, 1998 or 1999 (N=66,664). For each vaccination system we described the cumulative proportion HPV vaccination initiation and completion over time. We used life table analysis to calculate age-specific rates of HPV vaccination initiation and completion. Analyses were done separately for higher income and low income groups. Under non school-based, co-payment vaccination the proportions HPV vaccination initiation and completion slowly rose over time. By age 17, the proportion HPV vaccination initiation/completion was 0.75 (95% CI 0.74-076)/0.66 (95% CI 0.65-0.67). The median age at vaccination initiation/completion was 14.4 years (95% CI 14.4-14.5)/15.4 years (95% CI 15.3-15.4). Socio-economic inequalities in coverage widened over time and with age. Under school-based, free vaccination rates of HPV vaccination initiation were substantially higher. By age 14,the proportion HPV vaccination initiation/completion was 0.90 (95% CI 0.90-0.90)/0.87 (95% CI 0.87-0.88). The median age at vaccination initiation/completion was 12.7 years (95% CI 12.7-12.7)/13.3 years (95% CI 13.3-13.3). Socio-economic inequalities in coverage and in age-specific coverage were substantially smaller. Copyright © 2015. Published by Elsevier Ltd.

Suicidal behavior among adolescents is not a well-explored public health problem. Health policy decision-making on suicidal behavior needs reliable information on the prevalence of suicidal ideation (SI) and its associated risk factors to produce health promotion and prevention programs. The Global School Health Survey is a self-administered survey done on a random probabilistic sample among students of the 7th, 8th, and 9th grades in the Lara State, Venezuela, school period 2003 to 2004. Point prevalence of SI and associated factors were included and the odds (OR) of having SI was calculated given selected factors. Two-thousand seventy (2070) respondents, of which 13.5 % reported having SI in the last 12 months, and in females more than males (14.6% vs. 11.7%). The OR for SI, according to an associated risk factor, were among (a) females: age > or = 14 years (2.2), worries (3.42), loneliness (8.8), ever had sexual intercourse (5.58), alcohol (8.43) and (b) males: having only one or non close friends (3.69), alcohol (12.36), ever had sexual intercourse (2.73). Behavioral risk factors are relatively new in the field of surveillance systems; therefore, results on SI should be cautiously taken into consideration and a wide discussion should be encouraged as we learn how to best use the results for health promotion and disease prevention.

Menarche is an important milestone in the development of female adolescents. The study assessed the age at menarche using recall, its seasonality, and association with marital and nutritional status (using mid-upper arm circumference [MUAC]) among 3,923 female adolescents aged 12-19 years in a rural area of Bangladesh. At the time of assessment, most (88%) adolescents had attained menarche at the mean (standard deviation [SD]) age of 12.8 (1.4) years. Age of onset of menarche among married adolescents (13%) occurred earlier than in those who were unmarried (12.6 +/- 1.3 years vs 12.9 +/- 1.4 years, p < 0.01). Age at menarche was negatively associated with MUAC after adjusting for age and marital status (beta = -0.10, p < 0.01). More than 50% of the adolescents had an onset of menarche during winter (chi2 = 634.97; p < 0.001), with peaks in December and January. In this rural population, the current age at menarche was found to be slightly lower than the previous estimates of 13.0 years in Bangladesh. An early onset of menarche was associated with season and better nutritional status of the female adolescents and may be associated with early marriage.

The study aimed to determine the association between body mass index (BMI)-for-age and health-related quality of life (HRQOL) among high school students in Tehran. A total of 465 high school students (227 girls and 238 boys) and their parents were participated in this cross-sectional study. Body weight and height of the students were measured. For assessing HRQOL, both adolescent self-report and parent proxy-report of the Persian version of Pediatric Quality of Life Inventory (PedsQL™4.0) questionnaire were completed by adolescents and their parents respectively. The prevalence of overweight and obesity (38.5%) was higher than severe thinness and thinness (2.8%). Mean of adolescent self-reported and parent proxy-reported HRQOL total score were 80.26 ± 12.07 and 81.30 ± 14.08 respectively. In terms of HRQOL subscale scores, the highest subscale score of HRQOL was reported in social functioning (87.27 ± 14.40) and the lowest score was reported in emotional functioning (69.83 ± 18.69). Based on adolescent self-report, adolescent boys had significantly higher mean score for total and all subscale scores of HRQOL compared with girls (P < 0.05). BMI-for-age was inversely correlated to adolescent self-reported HRQOL total score (r = -0.25, P < 0.05). Based on adolescents self-report, HRQOL total score was significantly different by body weight status (F = 16.16, P < 0.05). Normal weight adolescents had significantly higher HRQOL total score compared with overweight (mean difference: 7.32; P < 0.05) and obese adolescents (mean difference: 9.10, P < 0.05). The HRQOL total score was not significantly different between normal weight and underweight adolescents (mean difference: 1.65, P = 0.96). However, based on parent proxy-reports, HRQOL total score was not significantly different by body weight status (F = 2.64, P = 0.059). More than one-third of adolescents were overweight and obese. BMI-for-age was inversely correlated to adolescent self-reported HRQOL. Based on adolescents' perspective, overweight and obese adolescents had poorer HRQOL compared with normal weight adolescents. Intervention studies are needed to improve the HRQOL of overweight and obese adolescents in Tehran. © 2013 John Wiley & Sons Ltd.

We tested whether effects of the Strengthening Families Program for Youth 10-14 (SFP10-14) diffused from intervention participants to their friends. We also tested which program effects on participants accounted for diffusion. Data are from 5,449 students (51% female; mean initial age = 12.3 years) in the PROmoting School-community-university Partnerships to Enhance Resilience community intervention trial (2001-2006) who did not participate in SFP10-14 (i.e., nonparticipants). At each of five waves, students identified up to seven friends and self-reported past month drunkenness and cigarette use, substance use attitudes, parenting practices, and unsupervised time spent with friends. We computed two measures of indirect exposure to SFP10-14: total number of SFP-attending friends at each wave and cumulative proportion of SFP-attending friends averaged across the current and all previous post-intervention waves. Three years post-intervention, the odds of getting drunk (odds ratio = 1.4) and using cigarettes (odds ratio = 2.7) were higher among nonparticipants with zero SFP-attending friends compared with nonparticipants with three or more SFP-attending friends. Multilevel analyses also provided evidence of diffusion: nonparticipants with a higher cumulative proportion of SFP-attending friends at a given wave were less likely than their peers to use drugs at that wave. Effects from SFP10-14 primarily diffused through friendship networks by reducing the amount of unstructured socializing (unsupervised time that nonparticipants spent with friends), changing friends' substance use attitudes, and then changing nonparticipants' own substance use attitudes. Program developers should consider and test how interventions may facilitate diffusion to extend program reach and promote program sustainability.

Adolescent-perceived parent and teacher overestimation of mathematics ability: Developmental implications for students' mathematics task values.

PubMed

Gniewosz, Burkhard; Watt, Helen M G

2017-07-01

This study examines whether and how student-perceived parents' and teachers' overestimation of students' own perceived mathematical ability can explain trajectories for adolescents' mathematical task values (intrinsic and utility) controlling for measured achievement, following expectancy-value and self-determination theories. Longitudinal data come from a 3-cohort (mean ages 13.25, 12.36, and 14.41 years; Grades 7-10), 4-wave data set of 1,271 Australian secondary school students. Longitudinal structural equation models revealed positive effects of student-perceived overestimation of math ability by parents and teachers on students' intrinsic and utility math task values development. Perceived parental overestimations predicted intrinsic task value changes between all measurement occasions, whereas utility task value changes only were predicted between Grades 9 and 10. Parental influences were stronger for intrinsic than utility task values. Teacher influences were similar for both forms of task values and commenced after the curricular school transition in Grade 8. Results support the assumptions that the perceived encouragement conveyed by student-perceived mathematical ability beliefs of parents and teachers, promote positive mathematics task values development. Moreover, results point to different mechanisms underlying parents' and teachers' support. Finally, the longitudinal changes indicate transition-related increases in the effects of student-perceived overestimations and stronger effects for intrinsic than utility values.

To examine the sleep pattern and observe differences in sleep routines, phase preferences, mood, attendance, and academic performance among different adolescent age students. Secondly, to observe the age at which sleep phase transition and changes in sleep requirement become evident. A cross-sectional study was conducted among 501 students (aged 11-15 y) of a school in Delhi, India. Students were evaluated for their sleep patterns, sleep duration, habits of napping, quality of sleep, sleepiness, depression, phase preferences by self-reported school sleep habits survey questionnaire along with school performance and attendance. Significant differences were found in sleep pattern of students aged 11-12 y and 13-15 y. Bedtime shifted to a later time with increasing age but early morning schools kept the wake time same, leading to a decline in total sleep duration of older adolescents. Older adolescents had higher depression but poor attendance and academic performance. Prevalence of sleep deprivation increased with age, from 83.7% to 87.1% in 11-12 y to 90.5% to 92.5% in 13-15 y. The study clearly identifies 12-13 y as age of transition of sleep pattern among adolescents. Though significant differences were found in the academic performance, mood and attendance among preteens and teens but no direct association was seen between academic performances and sleep pattern. A complex multifactorial association between sleep patterns, attendance, mood and academic performance which may change over days, months, or years should be explored further in a longitudinal follow up study.

Throughout the world, alcohol consumption is common among adolescents. Adolescent alcohol use and misuse have prognostic significance for several adverse long-term outcomes, including alcohol problems, alcohol dependence, school disengagement and illicit drug use. The aim of this study was to evaluate whether randomisation to a community mobilisation and social marketing intervention reduces the proportion of adolescents who initiate alcohol use before the Australian legal age of 18, and the frequency and amount of underage adolescent alcohol consumption. The study comprises 14 communities matched with 14 non-contiguous communities on socioeconomic status (SES), location and size. One of each pair was randomly allocated to the intervention. Baseline levels of adolescent alcohol use were estimated through school surveys initiated in 2006 (N=8500). Community mobilisation and social marketing interventions were initiated in 2011 to reduce underage alcohol supply and demand. The setting is communities in three Australian states (Victoria, Queensland and Western Australia). Students (N=2576) will complete school surveys in year 8 in 2013 (average age 12). (1) lifetime initiation and (2) monthly frequency of alcohol use. Reports of social marketing and family and community alcohol supply sources will also be assessed. Point estimates with 95% CIs will be compared for student alcohol use in intervention and control communities. Changes from 2006 to 2013 will be examined; multilevel modelling will assess whether random assignment of communities to the intervention reduced 2013 alcohol use, after accounting for community level differences. Analyses will also assess whether exposure to social marketing activities increased the intervention target of reducing alcohol supply by parents and community members. ACTRN12612000384853.

With a broader aim of controlling pulmonary tuberculosis (TB) among foreigners, here, we have reported the findings of chest radiography screening for TB among international students at Japanese language schools in Osaka city. Between April 2011 and December 2013, 4,529 international students from 19 Japanese language schools in Osaka city underwent chest radiography for TB screening. The chest radiographs were studied in reference to the student's sex, age, nationality, and date of entry to Japan as well as any health conditions present at the time of screening. We further analyzed the bacterial information and pulmonary TB classification based on chest radiography findings of students who were identified to be positive for TB. Information on the implementation of health education was also gathered. The results revealed that 52.5% of the students who underwent chest radiography came from China, 20.3 % from South Korea, and 16.3% from Vietnam. Of the students, 52.9% were male and 47.1% were female. The median age of students was 23 years (range: 14-70 years). The median number of days from the first date of entry to Japan up until the radiography screening was 63 days. Based on the chest radiography findings, 71 students (1.6%) were suspected to have TB; however, further detailed examination confirmed that 19 students (0.4%) had active TB. This percentage is significantly higher than the 0.1% TB identification rate among residents in Osaka city of the same time period (P<0.001), which was also determined by chest radiography. The median age of the 19 TB positive patients was 23 years. Among them, 14 (73.7%) were male. The median time from the date of entry to Japan to the date of the chest radiography screening was 137 days. For 16 of those students, the entry to Japan was within 1 year of the radiography. Of the 19 TB positive patients, 16 (84.2%) did not have respiratory symptoms, 15 (79.0%) had sputum smear negative results, and 17 (89.5%) had no cavity. Health education was conducted in 11 schools (for a total of 12 times) in the 3-year period. A total of 257 language school staff and students attended the health education seminars. The identification rate of TB positive students in Japanese language schools was higher than that of the general residents in Osaka city. In addition, most of these students came to Japan within 1 year. It is also important to note that the majority of TB positive students had sputum smear negative results. This study proves that medical examination after entry to Japan would be useful for early detection of TB positive patients. Furthermore, it would be beneficial to conduct chest radiography screenings among students at language schools on a continuous basis. It is also necessary to provide health education to the staff and students in Japanese language schools. Effective methods of disseminating health education, especially on the topic of TB, should be considered.

1998-12-01

The present study is a detailed evaluation of age at smoking initiation among university male students in Kuwait based on a random sample of 664 students selected from all students during 1993. The Acturial Life Table analysis revealed that almost one tenth of the students initiated cigarette smoking between ages 16 and 17 with the rate of initiation increasing rapidly thereafter and reaching 30% by age 20 and almost 50% by the time they celebrate their 24th birthday. The most important environmental risk factor positively associated for smoking initiation was observed to be the history of smoking among siblings with a relative risk of 1.4. Compared to students of medicine and engineering, the students of other faculties revealed a higher risk in smoking initiation with an RR = 1.77 for sciences and commerce and 1.61 for other faculties (arts, law, education and Islamic studies). The analysis revealed a rising generation trend in cigarette smoking. There is a need for reduction of this trend among young adults in Kuwait and throughout other countries in the region.

To observe the influence of preventive acupuncture (PA) and preventive moxibustion (PM) at "Guanyuan" (CV 4) on the immune function in natural climacteric rats. A total of 160 female SD rats were randomized into control, PA and PM groups, the former one group was further divided into 10 month (mon), 12 mon, 14 mon and 16 mon subgroups, and the later two groups were further divided into 12 mon, 14 mon and 16 mon subgroups, with 16 rats in each. In addition, other 16 female SD rats aged 3.5 mon were used as the young control (YC) group. "Guanyuan" (CV 4) was punctured with an acupuncture needle and the needle was retained for 20 min, or given with one ignited moxa-cone from the age of 10 mon on. The treatment was conducted twice every week, 8 weeks altogether. The expression of HSP 70 and HSP 70 mRNA of the spleen tissue was detected by using immunohistochemistry and in situ hybridization respectively, and serum IL-2 and TNF-alpha contents were assayed by using radio-immunoassay. In comparison with YC group, 1) the expression of spleen HSP 70 and HSP 70 mRNA increased significantly in 10 mon control (mon-C), 12 mon-PM and 12 mon-PA groups, and 14 mon-PA group (only HSP 70 mRNA) (P < 0.05, P < 0.01); 2) HSP 70 expression decreased remarkably in 14 mon-C, 16 mon-C and 16 mon-PA groups (P < 0.05, P < 0.01); 3) IL-2 contents decreased evidently in 12 mon-C and 14 mon-C groups, and TNF-alpha contents increased obviously in 12 mon-PM, 12 mon-PA and 16 mon-C groups (P < 0.05). In comparison with the corresponding same age control groups, HSP 70 and HSP 70 mRNA expression increased significantly in 12 mon-PM and 12 mon-PA groups, 14 mon-PM and 16 mon-PM (HSP 70 only), 14 mon-PA (HSP 70 mRNA only) groups (P < 0.05, P < 0.01); IL-2 level of 12 mon-PM group, and TNF-alpha contents of 12 mon-PM and 12 mon-PA groups increased markedly (P < 0.05, P < 0.01). No significant differences were found between PM and PA groups in most different age groups (P > 0.05). Both preventive acupuncture and preventive moxibustion can upregulate the expression of spleen HSP 70 and HSP 70 mRNA and serum IL-2 and TNF-alpha levels, which may contribute to their effects in enhancing the immune function in menopausal rats.

Photoaging Mobile Apps in School-Based Tobacco Prevention: The Mirroring Approach.

Brinker, Titus Josef; Seeger, Werner; Buslaff, Fabian

2016-06-28

Most smokers start smoking during their early adolescence, often with the idea that smoking is glamorous. Adolescent smoking can best be prevented through health education at schools. Interventions that take advantage of the broad availability of mobile phones as well as adolescents' interest in their appearance may be a novel way to improve prevention. In this first pilot study, we aimed to use mobile phone technology in accordance with the theory of planned behavior to improve school-based tobacco prevention. We used a free photoaging mobile phone app ("Smokerface") in three German secondary schools via a novel method called mirroring. The students' altered three-dimensional selfies on mobile phones or tablets were "mirrored" via a projector in front of their whole grade. Using an anonymous questionnaire, we then measured on a 5-point Likert scale the perceptions of the intervention among 125 students of both genders (average age 12.75 years). A majority of the students perceived the intervention as fun (77/125, 61.6%), claimed that the intervention motivated them not to smoke (79/125, 63.2%), and stated that they learned new benefits of non-smoking (81/125, 64.8%). Only a minority of students disagreed or fully disagreed that they learned new benefits of non-smoking (16/125, 12.8%) or that they were themselves motivated not to smoke (18/125, 14.4%). We have presented a novel method to integrate photoaging in school-based tobacco prevention that affects student peer groups and considers the predictors of smoking in accordance with the theory of planned behavior.

This is the first randomized trial testing whether heavy-drinking undergraduates mandated to the Brief Alcohol Screening and Intervention for College Students (BASICS) program following a campus alcohol violation would benefit as much as heavy-drinking volunteers up to 1 year postintervention using control groups with high-risk drinkers to model disciplinary-related and naturalistic changes in drinking. Participants (61% male; 51% mandated; 84% Caucasian; M age = 20.14 years) were screened for heavy drinking and randomized to BASICS (n = 115) or assessment-only control (n = 110). Outcome measures (drinking, alcohol problems) were collected at baseline, 4 weeks, 3, 6, and 12 months postintervention. At 4 weeks postintervention, intent-to-treat multilevel longitudinal models showed that regardless of referral group (mandated or volunteer), BASICS significantly decreased weekly drinking, typical drinks, and peak drinks relative to controls (ds = .41-.92). BASICS had a large effect on decreases in alcohol problems (d = .87). At 12 months postintervention, BASICS participants (regardless of referral group) reported significantly fewer alcohol problems (d = .56) compared with controls. Significant long-term intervention gains for peak and typical drinks were sustained in both referral groups relative to controls (ds = .42; .11). Referral group had no significant main effect and did not interact with intervention condition to predict outcomes. Given that BASICS was associated with less drinking and fewer alcohol problems (even among heavier drinking mandated students up to 1 year postintervention), provision of BASICS-style programs within disciplinary settings may help reduce heavy and problematic drinking among at-risk students.

A pilot yoga physical education curriculum to promote positive body image.

PubMed

Cox, Anne E; Ullrich-French, Sarah; Howe, Holly S; Cole, Amy N

2017-12-01

We examined the effects of a pilot yoga-based physical education (PE) curriculum by testing for change in trait body surveillance, physical self-worth, and body appreciation. Further, we examined the relationships among change in body image variables and the role of state mindfulness in predicting state body surveillance during classes. Adolescents participated in 12 weeks of yoga-based (n=20; M age =16.45, 90% female) or traditional (n=23;M age =14.52, 57% female) PE. Results showed significant (p=.004), moderate decreases in trait body surveillance and minimal nonsignificant (p=.11) increases in physical self-worth. Change in trait body surveillance was inversely related to change in physical self-worth and body appreciation in yoga participants. Multi-level modeling analyses revealed that more mindful students also surveyed their body less during class. Intentionally structured yoga participation may support positive body image among adolescents. Copyright © 2017 Elsevier Ltd. All rights reserved.

Preventing the link between SES and high-risk behaviors: "value-added" education, drug use and delinquency in high-risk, urban schools.

Tobler, Amy L; Komro, Kelli A; Dabroski, Alexis; Aveyard, Paul; Markham, Wolfgang A

2011-06-01

We examined whether schools achieving better than expected educational outcomes for their students influence the risk of drug use and delinquency among urban, racial/ethnic minority youth. Adolescents (n = 2,621), who were primarily African American and Hispanic and enrolled in Chicago public schools (n = 61), completed surveys in 6th (aged 12) and 8th (aged 14) grades. Value-added education was derived from standardized residuals of regression equations predicting school-level academic achievement and attendance from students' sociodemographic profiles and defined as having higher academic achievement and attendance than that expected given the sociodemographic profile of the schools' student composition. Multilevel logistic regression estimated the effects of value-added education on students' drug use and delinquency. After considering initial risk behavior, value-added education was associated with lower incidence of alcohol, cigarette and marijuana use; stealing; and participating in a group-against-group fight. Significant beneficial effects of value-added education remained for cigarette and marijuana use, stealing and participating in a group-against-group fight after adjustment for individual- and school-level covariates. Alcohol use (past month and heavy episodic) showed marginally significant trends in the hypothesized direction after these adjustments. Inner-city schools may break the links between social disadvantage, drug use and delinquency. Identifying the processes related to value-added education in order to improve school environments is warranted given the high costs associated with individual-level interventions.

2012-04-01

The Student-Teacher Relationship Scale (STRS) is widely used to examine teachers' relationships with young students in terms of closeness, conflict, and dependency. This study aimed to verify the dimensional structure of the STRS with confirmatory factor analysis, test its measurement invariance across child gender and age, improve its measurement of the dependency construct, and extend its age range. Teachers completed a slightly adapted STRS for a Dutch sample of 2335 children aged 3 to 12. Overall, the 3-factor model showed an acceptable fit. Results indicated metric invariance across gender and age up to 8years. Scalar invariance generally did not hold. Lack of metric invariance at ages 8 to 12 primarily involved Conflict items, whereas scale differences across gender and age primarily involved Closeness items. The adapted Dependency scale showed strong invariance and higher internal consistencies than the original scale for this Dutch sample. Importantly, the revealed non-invariance for gender and age did not influence mean group comparisons. Copyright © 2011 Society for the Study of School Psychology. Published by Elsevier Ltd.

Mental health of Aboriginal children and adolescents in violent school environments: protective mediators of violence and psychological/nervous disorders.

PubMed

Kaspar, Violet

2013-03-01

The effect of school violence on mental health was examined among 12,366 Aboriginal children and adolescents, primarily First Nations, Métis, and Inuit residing off reservations in the Canadian provinces and territories. Analyses were based on the 2006 Aboriginal Peoples' Survey, a postcensal national survey of Aboriginal youth aged 6-14 years. More than one-fifth of students in the sample attended schools where violence was perceived as a problem. The occurrence of psychological or nervous disorders was about 50% higher among students exposed to school violence than among other students. School violence was a significant predictor of mental health difficulties, irrespective of socioeconomic and demographic characteristics. Virtually the entire effect was mediated by interpersonal processes, or negative quality of parent-child and peer relationships, while the effect was not explained by cultural detachment through lack of interactions with Elders and traditional language ability/use. Results underscored school violence as a significant public health concern for Aboriginal elementary and high school students, and the need for evidence-based mental health interventions for at-risk populations.

This is a cross sectional descriptive community-based study. The aim was to assess the prevalence of anaemia among quranic schoolchildren in khalawi Wad EL Magboul village, rural Rufaa, Gezira State, central Sudan. A sample of 180 male participants were included in the study. Informed consent was obtained. Venous blood samples were obtained to measure the hematological parameters and blood films for malaria parasites. Urine and stool analyses were also done. Data were analyzed using SPSS. The mean age of participants was 12.31 years (SD +/- 2.26). The mean Hb value was 11.75g/dl and it was statistically significant correlation when compared with the mean Hb reference value (13.5g/dl) P value 0,000 (95% CI). Regarding period of stay in the khalwa up to the time of the study, 88 (49.28%) for one year, 54 (30.24%) for 2 years, 22 (12.32%) for 3 years and 16 (8.96%) for more than 3 years. About 77 students (42.78%) were pale on clinical examination. The Mean Cell Hemoglobin (MCH) mean value was 25.58 pg ( 3.55). Many conditions known to be associated with anemia were found; 49 students (27.2%) had a positive blood films for falciparum malaria, 14 students (7.8%) were found to have haematuria and ova of S. haematobium, In169 students (93.4%) stool examination was negative , while 11 students (6.6%) had intestinal worms (Enterobius vermicularis). Majority of the study participants had iron deficiency anaemia, followed by haemolytic, macrocytic and sickle cell anaemia. This might have negative health and educational implications.

The aim of this study was to assess the distribution of chronotypes in a sample of Iraqi Kurdish medical students. A descriptive cross-sectional study was conducted at the Hawler Medical University College of Medicine in Erbil City, Iraq, between 1(st) January and 31(st) March 2013. A total of 580 students were given the reduced version of the Horne and Ostberg Morningness-Eveningness Questionnaire (MEQr), a close-ended self-administered questionnaire. Of the 580 students, 130 (22.4%) were male and 450 (77.6%) were female. The mean age ± standard deviation was 20.3 ± 1.45 years, with a range of 17-24 years. Most of the students (52.6%) were in the intermediate class, followed by morning type (24.1%) and evening type (23.3%). Significant gender differences were detected in the proportion of morning, intermediate and evening types (P <0.001). The mean scores for the female students were 14.8 ± 2.2 and the mean scores for the male students were 14.6 ± 7.3, with no statistically significant differences (P = 0.45). Students in the College of Medicine were mostly classified as intermediate types. The morning type was more common among this student population, particularly male students, than has been reported in similar age groups in some Western countries. There was a significant gender difference in the proportion of MEQr types.

ABSTRACT Objective: The aim of the study was to determine the association between weight-teasing and physical activity in students from public schools of Curitiba, Paraná (Southern Brazil). Methods: The sample consisted of 95 students (48 boys and 47 girls) aged 12 to 14 years old. The Perception of Weight Teasing (POTS) and The Perception of Weight Teasing during Physical Activity Scale assessed the frequency of weight-teasing experienced by the participants. Accelerometers measured physical activity. BMI assessed the weight status of the participants. Pearson correlations analyzed the association between the teasing and physical activity variables at a significance level of 0.05. Results: The relationship between teasing variables and physical activity was not significant. A large proportion of participants failed to meet the recommended levels of physical activity regardless of sex (72%), and girls were significantly less physically active than boys (56.3% of boys and 89.4% of girls; p<0.01). Conclusions: Some participants were targets of weight-teasing, but teasing was not related to physical activity. Interventions are necessary to educate middle school students about the harmful consequences of weight teasing. PMID:28977290

Purpose Bullying has become a significant public health issue, particularly among youth. This study documents cyberbullying, homophobic bullying and bullying at school or elsewhere and their correlates among both heterosexual and sexual-minority high school students in Quebec (Canada). Method A representative sample of 8,194 students aged 14–20 years was recruited in Quebec (Canada) high schools. We assessed cyberbullying, homophobic bullying and bullying at school or elsewhere in the past 12 months and their association with current self-esteem and psychological distress as well as suicidal ideations. Results Bullying at school or elsewhere was the most common form of bullying (26.1%), followed by cyberbullying (22.9%) and homophobic bullying (3.6%). Overall, girls and sexual-minority youth were more likely to experienced cyberbullying and other form of bullying as well as psychological distress, low self-esteem and suicidal ideations. The three forms of bullying were significantly and independently associated with all mental health outcomes. Conclusions The results underscore the relevance of taking into account gender and sexual orientation variations in efforts to prevent bullying experience and its consequences. PMID:26047959

The purpose of this study was to investigate the role of Internet usage among adolescents in Northern Cyprus. A total of 686 adolescents (mean age of 14.4 years, range of 12-17 years) were recruited from elementary and high schools. Results showed that the Internet was used primarily by male students. Adolescents used the Internet generally for entertainment and communication. The quality of chat on the Internet was studied, and it was found that adolescents generally introduce themselves differently while chatting. Also, the type of games on the Internet and the correlation between playing these games and aggression was studied in this research. It was found that mostly violent games were played on the Internet and playing these games were related to anti-social aggression and aggression toward the self. Research findings indicated that 1.1% of the students who used the Internet were pathological Internet users. These pathological Internet users visited significantly more chat sites, mp3 sites, pornographic sites, and shopping sites than other users. Also, it was found that students' grade point average (GPA) decreased when pathological Internet usage increased.

Oral vs. Vaginal Sex Experiences and Consequences Among First-Year College Students

To fully understand late adolescents’ experiences of oral sex, we must consider both risk and normative developmental perspectives. Sexual experiences include a range of behaviors, but research on sexual behaviors and consequences focuses primarily on vaginal sex. Oral sex occurs at rates similar to vaginal sex, and carries some, though less, risk than vaginal sex. The current study examined the event-level prevalence and consequences of oral sex compared to vaginal sex with other-sex partners in first year college students. Daily data were from recently sexually active first year college students (N = 253 people, 834 days; M age, 18.4 years; SD = 0.4; 56% female; 31% Hispanic/Latino; 17% African American, 14% Asian American/Pacific Islander, 25% European American, 12% multiracial) who reported on sexual behaviors and consequences. Both positive (intimacy, physical satisfaction) and negative (worrying about health, guilt) consequences were less common for oral than vaginal sex. Gender differences suggested that female adolescents may find vaginal sex more rewarding than oral sex whereas male adolescents may find them equally rewarding. PMID:26597646

2016-09-01

The lack of diversity in physics is a known problem, and yet efforts to change our demographics have only had minor effects during the last decade. I will explain some of the hidden barriers that dissuade underrepresented minorities in becoming physicists using a framework borrowed from sociology, Maslow's hierarchy of needs. I will draw from current research at the undergraduate to faculty levels over a variety of STEM fields that are also addressing a lack of diversity. I will also provide analysis from the Joint Institute for Nuclear Astrophysics Center for the Evolution of Elements (JINA-CEE) outreach programs to understand the likelihood of current K-12 students in becoming physicists. Specifically, I will present results from the pre-surveys from our Art 2 Science Camps (ages 8-14) about their attitudes towards science as well as results from analysis of teacher recommendations for our high school summer program. I will conclude with a positive outlook describing the pipeline created by JINA-CEE to retain students from middle school through college.

Multiplatform digital media use and gaming have been increased in recent years. The aim of this study was to examine associations between sociodemographics and digital gaming behavior characteristics (i.e., gaming time, medium, and genres) with problematic gaming behavior in adolescents. A convenience sample of Finnish junior high school students (n = 560; mean age 14 years, ranging from 12 to 16 years) participated in the cross-sectional survey, of which, 83% (n = 465) reported having played digital games regularly. Sociodemographic data, different forms of digital media use, gaming behavior characteristics and problematic gaming behavior was assessed. Study participants spent on average one hour per day playing digital games; casual games (23.9%), shooting games (19.8%), and sport games (12.9%), were the most popular games among participants. By using regression analysis, a blended family structure and gaming time related positively to problematic gaming behavior. Preferences for game genres such as solo, Massively Multiplayer Online Role-Playing and strategy-management games were also positively associated with problematic use of digital games. These findings provide knowledge that can be utilized in the prevention of the possible negative consequences of digital gaming.

Statistics on China's 1996 social development.

PubMed

1997-04-01

1996 statistics released by China's State Statistical Bureau reflect the level of social development. Statistics are provided on education, health, population, income, employment, housing, social welfare, and environmental degradation. The number of higher education institutions declined slightly between 1995 and 1996. In 1996 there were 1032 universities and colleges and 1138 adult education higher learning institutions. The number of students enrolled in universities and colleges increased by 40,000 to 966,000. The total university population numbered 3.02 million in 1996. Increases in students occurred in adult education and graduate schools. Secondary vocational education expanded to 10.1 million students, or 56.8% of all senior middle school students. The 50.48 million junior middle school students represent an enrollment rate of 82.4%. The 136.15 million primary school students represent a 98.8% enrollment rate. About 4.07 million adults gained literacy. Preventive health work and rural public health work were strengthened in 1996. The birth rate in 1996 was 16.98/1000. The death rate was 6.56/1000. The 1996 end-of-the-year population was 1.22389 billion, an increase of 12.68 million over 1995. 29.4% were urban residents. The average family size was 3.70. 26.4% were children aged 0-14 years, and 9.4% were aged over 65 years. The average annual disposable income per capita was 4839 yuan for urban residents, 6235 yuan in provincial capital cities, and 1926 yuan for rural residents. Rural residents received the highest increase in income (9%) at constant prices. 688.5 million people were employed, of which 149.6 million were urban workers. The labor force increased by 9 million people during the year. 360 million sq. m of new buildings were added in urban areas in 1996; 760 million sq. m were added in rural areas.

Stronger vection in junior high school children than in adults.

PubMed

Shirai, Nobu; Imura, Tomoko; Tamura, Rio; Seno, Takeharu

Previous studies have shown that even elementary school-aged children (7 and 11 years old) experience visually induced perception of illusory self-motion (vection) (Lepecq et al., 1995, Perception, 24, 435-449) and that children of a similar age (mean age = 9.2 years) experience more rapid and stronger vection than do adults (Shirai et al., 2012, Perception, 41, 1399-1402). These findings imply that although elementary school-aged children experience vection, this ability is subject to further development. To examine the subsequent development of vection, we compared junior high school students' (N = 11, mean age = 14.4 years) and adults' (N = 10, mean age = 22.2 years) experiences of vection. Junior high school students reported significantly stronger vection than did adults, suggesting that the perceptual experience of junior high school students differs from that of adults with regard to vection and that this ability undergoes gradual changes over a relatively long period of development.

Individual differences in number sense correlate with mathematical ability and performance, although the presence and strength of this relationship differs across studies. Inconsistencies in the literature may stem from heterogeneity of number sense and mathematical ability constructs. Sample characteristics may also play a role as changes in the relationship between number sense and mathematics may differ across development and cultural contexts. In this study, 4,984 16-year-old students were assessed on estimation ability, one aspect of number sense. Estimation was measured using 2 different tasks: number line and dot-comparison. Using cognitive and achievement data previously collected from these students at ages 7, 9, 10, 12, and 14, the study explored for which of the measures and when in development these links are observed, and how strong these links are and how much these links are moderated by other cognitive abilities. The 2 number sense measures correlated modestly with each other (r = .22), but moderately with mathematics at age 16. Both measures were also associated with earlier mathematics; but this association was uneven across development and was moderated by other cognitive abilities.

To preliminarily survey the intakes of energy and macronutrients in rural boarding school students and analyse the affect factors of discrepancies between different sex and age groups. A total of 1834 rural boarding junior high school first grade students were selected from 16 provinces, and stratified cluster sampling method was used. The method of weight recording and three days dietary recall were used to investigate the diet of boarding school students. The ratios which reached the EER of energy intakes in boy and girl groups were 37.0% and 46.7% (P < 0.05) respectively, and the proportion of the intakes level of EER among the age groups of 11y ~ and 14y ~ for both boys and girls were 93.4%, 81.1% (P < 0.05) and 102.1%, 87.1% (P < 0.05) respectively. The ratios which reached the EAR of protein intakes in boy and girl groups were 57.7% and 61.4% ( P > 0.05) respectively, and the proportion of the intakes level of EAR among the age groups of 11y ~ and 14y ~ for both boys and girls were 124.8%, 107.3% (P > 0.05) and 134.8%, 112.1% (P < 0.05) respectively. The ratios which reached the EAR of total carbohydrate intakes in boy and girl groups were 85.0% and 77.5% (P < 0.05) respectively, and the proportion of the intakes level of EAR among the age groups of 11y ~ and 14y ~ for both boys and girls were 202.0% and 240.0% (P < 0.05), 180.1% and 205.4% (P < 0.05 ) respectively. The ratios which reached the AMDR of total fat intakes in boy and girl groups were 25.4% and 22.0% (P > 0.05) respectively, and among the age groups of 11y ~ and 14y ~ for both boys and girls were 21.8% and 30.5% (P < 0.05), 20.2% and 25.5% (P > 0.05) respectively. Double burden of nutrient might exist in the rural boarding schools. The status of nutrition could be improved evidently, by fulfilling the relative national policies, promoting the balance of the nutrition supplying in schools, and enriching the boarding students' knowledge of nutrition.

This study investigates the prevalence of asthma and asthma-related symptoms in New Orleans inner-city schoolchildren. A cross-sectional survey of 1535 elementary, middle, and high school children (aged 5-18) was conducted by using the International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire. Lifetime prevalence of wheezing was 39.4%, and lifetime prevalence of asthma was 24.4%. Wheezing during the previous 12 months was reported by 25.7% of the sample. Twenty-one percent of respondents reported having one or more attacks of wheezing per year, with 5.6% reporting four or more attacks per year. Many participants reported sleep disturbance (15.4%), with 6.2% reporting sleep disturbance more than once a week. The 12-month rate of speech limitation due to asthma exacerbation was 6.6%. Exercise-induced asthma was reported by 16.9% of the students, and nocturnal cough (not associated with cold) was reported by 27.3%. Overall, boys reported higher rates of symptoms than girls, and younger children (aged 6-7) reported greater symptoms than older children (aged 13-14). These findings show that prevalence of asthma in this population is elevated, and the ISAAC written questionnaire successfully identified inner-city children at risk for asthma in New Orleans.

To compare the age at menarche obtained by recall method according to the time elapsed since the event, in order to verify the importance of the recall bias. Were evaluated 1,671 girls (7-18 years) at schools in Campinas-SP regarding the occurrence of menarche by the status quo method (menarche: yes or no) and the recall method (date of menarche, for those who mentioned it). The age at menarche obtained by the status quo method was calculated by logit, which considers the whole group, and the age obtained by the recall method was calculated as the average of the mentioned age at menarche. In this group, the age at menarche was obtained by the difference between the date of the event and the date of birth. Girls who reported menarche (883, 52.8%) were divided into four groups according to the time elapsed since the event. To analyze the results, we used ANOVA and logistic regression for the analysis, with a significance level of 0.05. The age at menarche calculated by logit was 12.14 y/o (95% CI 12.08 to 12.20). Mean ages obtained by recall were: for those who experienced menarche within the previous year 12.26 y/o (±1.14), between > 1-2 years before, 12.29 y (±1.22); between > 2-3 years before, 12.23 y/o (±1.27); and more than 3 years before, 11.55y/o (±1.24), p < 0.001. The age at menarche obtained by the recall method was similar for girls who menstruated within the previous 3 years (and approaches the age calculated by logit); when more than 3 years have passed, the recall bias was significant.

Objective. Students with severe learning disabilities often show signs of anxiety, depression, and problem behaviors such as inattention and conduct problems. Mindfulness-based interventions (MBIs) in school settings constitute a promising option to alleviate these co-occurring symptoms. This pilot study aimed to evaluate the impact of an MBI on symptoms and behaviors of elementary school students with severe learning disabilities. Method. A one-group pretest-posttest design was used. The sample comprised 14 students aged 9 to 12 years with special education needs. Both student-report and teacher-report of the Behavior Assessment System for Children, Second Edition were used. Results. Repeated-measures analyses of variance revealed a significant impact of the MBI on symptoms and behaviors such as anxiety, depression, inattention, aggression, and conduct problems. Effect sizes for all variables were considered large (partial η2 = .31-.61). Conclusion. These preliminary results indicate that MBIs can reduce the frequency of symptoms and problem behaviors often found in children with learning disabilities in elementary schools. Further multiple baseline experimental trials with a long-term follow-up are warranted to establish more robustly the effect of MBIs for children with learning disabilities.

2018-03-01

This cross-sectional study examined how the progression and consistency of students' understanding of thermal concepts in everyday contexts changes across the grade levels. A total of 656 Turkish students from Grade 8 (age 13-14), Grade 10 (age 15-16), and the first year of college (age 19-20) participated in the study. The data were analysed using statistical procedures (descriptive and inferential). Findings indicated a substantial progression in the students' scientific understanding of thermal concepts across grade levels. In addition, the students' alternative conceptions about thermal concepts generally decreased in frequency across grade levels, but certain alternative conceptions were observed in every grade level to a similar extent. Even though the number of students who consistently used scientific ideas increased across grade levels, the number of students who consistently used non-scientific ideas decreased across grade levels. However, the number of students who used scientific and non-scientific ideas inconsistently generally increased as they progressed in the science curriculum. These findings can be associated with either fragmentation or alternative conceptions that result from the gradual enrichment processes students experience when they try to integrate scientific concepts into their conceptual frameworks.

To determine the prevalence of overweight and obesity according to the criteria of the WHO and CDC in adolescents from an urban district of Lima, Peru 2012. This cross-sectional study included 1,743 school children of 12 to 17 years of age selected from ten public and private educational institutions, using a randomized and stratified sample of "conglomerados" (neighborhoods). In the selected schools, weight and height were measured. For the diagnosis of overweight and obesity, criteria from the WHO and CDC were used. For data analysis, descriptive and inferential statistics were performed. According to the WHO criteria, the prevalence of overweight was 33.7% (95% CI 31.5-36.0) and obesity was 14.4% (95% CI 12.8-16.1). According to CDC criteria, the prevalence of overweight was 26.5% (95% CI 24.4-28.6) and obesity was 13.9% (95% CI 12.3-15.6). The prevalence of overweight and obesity was significantly higher in males aged 12 and 13 years old and private educational institutions (p<0.05). We found very good agreement between the WHO and CDC criteria for the diagnosis of overweight and obesity. A high prevalence of overweight and obesity was found, predominantly in male students between 12 and 13 years and private educational institutions. It is necessary to initiate intervention measures that can contribute to the prevention of chronic diseases in adulthood, secondary to obesity in adolescence.

Time to symptom resolution, return to school, and return to play after a sport-related concussion in children and adolescents (8-17 years of age) was examined using a retrospective cohort design. A total of 198 patients aged 8 to 17 years were included, with a mean age of 13.5 years (SD = 2.2). Patients aged 8 to 12 years were symptom-free in a median of 12.0 (range 1-60) days whereas 13- to 17-year olds were symptom-free in a median of 14.0 (range 1-300) days (P = .04). Patients aged 8 to 12 years returned to learn in a median of 4.0 (range 0-30) days compared with 2.5 (range 0-55.0) days in 13- to 17-year-olds (P = .86). Patients aged 8 to 12 years returned to play in a median of 14.0 (range 4-75) days compared with a median of 19.5 (range 5-75) days in 13- to 17-year-olds (P = .06). These results indicate that children and adolescents generally take 2 to 4 weeks to recover from a sport-related concussion. © The Author(s) 2015.

2017-02-01

To evaluate whether text-messaging programs can improve reproductive health among adolescent girls in low- and middle-income countries. We conducted a cluster-randomized controlled trial among 756 female students aged 14 to 24 years in Accra, Ghana, in 2014. We randomized 38 schools to unidirectional intervention (n = 12), interactive intervention (n = 12), and control (n = 14). The unidirectional intervention sent participants text messages with reproductive health information. The interactive intervention engaged adolescents in text-messaging reproductive health quizzes. The primary study outcome was reproductive health knowledge at 3 and 15 months. Additional outcomes included self-reported pregnancy and sexual behavior. Analysis was by intent-to-treat. From baseline to 3 months, the unidirectional intervention increased knowledge by 11 percentage points (95% confidence interval [CI] = 7, 15) and the interactive intervention by 24 percentage points (95% CI = 19, 28), from a control baseline of 26%. Although we found no changes in reproductive health outcomes overall, both unidirectional (odds ratio [OR] = 0.14; 95% CI = 0.03, 0.71) and interactive interventions (OR = 0.15; 95% CI = 0.03, 0.86) lowered odds of self-reported pregnancy for sexually active participants. Text-messaging programs can lead to large improvements in reproductive health knowledge and have the potential to lower pregnancy risk for sexually active adolescent girls.

Tics are the most frequent movement disorder in children and they are most prevalent during the school-age years. Most tics are transitory; however, certain tics can be chronic, causing negative repercussions at school, within the family, and socially. In some cases, tics are associated with obsessive compulsive disorder, attention-deficit hyperactivity disorder (ADHD) and other conditions that require diagnosis and prompt treatment. In South America, there are no indexed studies determining the prevalence of tics in school-age children. The aim of this study was to establish the prevalence of tics in schoolchildren aged 6 to 12 years. From 16 000 students aged 6 to 12 years who were enrolled in first to fifth grade, a sample of 346 school-aged children was chosen via a multistage sampling process that randomized the educational systems in terms of proportional size and the stratification between public and private schools and adjusted for the design effect. The students were screened and those who were positive for tics underwent clinical evaluations and semistructured interviews by the researchers to determine the prevalence of the disease. The parents and teachers of 323 students returned our surveys (93.3%). One hundred thirty-eight students (42.7%) were considered positive for tics based on parents' and teachers' reports. The clinical evaluation established a 17.97% prevalence of tics (58 students), and 25 students (43.2%) also met diagnostic criteria for ADHD. Of the students with tics, 27.6% presented with transitory tics, and 72.4% presented with chronic tics. Gilles de la Tourette syndrome was detected in 11 of the children (3.4%). The average age of child with tics was 9 ± 1.5 years, and the majority of the children with tics attended third grade at a basic primary school. Children from public and private schools were equally likely to present with tics. Tics are noteworthy in our field and are associated with other neurobehavioral disorders, such as ADHD. Both tic disorders and ADHD require diagnosis and prompt treatment to promote social and school performance.

Dental caries occurrence, distribution, oral health status and corresponding treatment needs in 12 - 15 year old children are useful tools for evaluation of oral health. Dental caries status along with its treatment needs was recorded according to World Health Organization (WHO) index (1997) in 366 children from five schools within Jorpati Village Development Committee (VDC), Kathmandu. Dental caries was diagnosed in 156 (42.6%) children, out of which 122 (78.21%) had caries in permanent teeth, 26 (16.67%) had caries in primary teeth, and 8 (5.13%) had caries in both dentition. The age wise distribution of dental caries showed the highest prevalence among 12 year old students (23.8%) and the lowest among 15 year olds (3.8%). Among the female students (177), 43.5% showed presence of dental caries, while the prevalence among male students (179) was 41.8%.Out of the total number of teeth affected by dental caries (336), 273 (81.25%) were permanent teeth and 63 (18.75%) were primary teeth. The intra arch distribution of dental caries in permanent as well as primary dentition was statistically significant (P < 0.05). Restorative treatment (89.38%) was the main need in permanent dentition, and endodontic treatment (60.32%) in primary dentition. Chronologic enamel hypoplasia was found in 14 (3.83%) of the total population, and 62 (16.94%) required oral prophylaxis. These findings are significant as they can initiate further research in this area, which may help establish reliable baseline data for implementation of preventive oral health programs.

The Tragedy of the Unexamined Cat: Why K-12 and University Education Are Still in the Dark Ages and How Citizen Science Allows for a Renaissance.

Dunn, Robert R; Urban, Julie; Cavelier, Darlene; Cooper, Caren B

2016-03-01

At the end of the dark ages, anatomy was taught as though everything that could be known was known. Scholars learned about what had been discovered rather than how to make discoveries. This was true even though the body (and the rest of biology) was very poorly understood. The renaissance eventually brought a revolution in how scholars (and graduate students) were trained and worked. This revolution never occurred in K-12 or university education such that we now teach young students in much the way that scholars were taught in the dark ages, we teach them what is already known rather than the process of knowing. Citizen science offers a way to change K-12 and university education and, in doing so, complete the renaissance. Here we offer an example of such an approach and call for change in the way students are taught science, change that is more possible than it has ever been and is, nonetheless, five hundred years delayed.

Anthropometry and neuromuscular fitness have been shown to relate with taekwondo (TKD) performance; however, little information is available on the variation of these fitness components by sex and age in athletes practicing this sport. The aim of the present study was to examine the anthropometry and neuromuscular fitness of TKD athletes by sex and age. A total of 393 athletes (7-48 years old), separated into six age groups (7-9, 10-11, 12-13, 14-17, 18-32, and 33+), were examined for anthropometry and performed a series of neuromuscular fitness tests (flexibility, agility, muscle power, and isometric strength). An age × sex interaction on body mass, body height, and body fat percentage (BF, p ≤0.003, η 2 ≥0.045), but not on body mass index ( p =0.172, η 2 =0.020), was shown, where a larger increase in body mass and body height from 12-13 to 14-17 groups was observed in males than in females, and the sex difference in BF increased from 12-13 to 14-17 age group. An age × sex interaction on sit-and-reach (SAR) test, mean power output in the Bosco test, and Abalakov jump ( p ≤0.038, η 2 ≥0.031) was observed with larger differences between 12-13 and 18-32 groups in males than in females. In SAR, it was remarkable that the male athletes achieved similar scores as female athletes in the 18-32 group. An age × sex group interaction on measures of isometric muscle strength (right and left handgrip, trunk, and legs) was also shown ( p ≤0.002, η 2 ≥0.068), where larger differences in male than female athletes were observed between the 12-13 and 14-17 groups. From a practical perspective, coaches can use these findings as reference for the evaluation of their athletes. Because the anthropometric characteristics and neuromuscular fitness varied by sex (i.e., highest scores in males, except flexibility) and age (i.e., highest scores in the 18-32 age group) with unique sport-specific patterns in TKD athletes, these findings would be important for the development of specific training programs.

The age threshold of 14 years is relevant in Italy as the minimum age for criminal responsibility. It is of utmost importance to evaluate the diagnostic accuracy of every odontological method for age evaluation considering the sensitivity, or the ability to estimate the true positive cases, and the specificity, or the ability to estimate the true negative cases. The research aims to compare the specificity and sensitivity of four commonly adopted methods of dental age estimation - Demirjian, Haavikko, Willems and Cameriere - in a sample of Italian children aged between 11 and 16 years, with an age threshold of 14 years, using receiver operating characteristic curves and the area under the curve (AUC). In addition, new decision criteria are developed to increase the accuracy of the methods. Among the four odontological methods for age estimation adopted in the research, the Cameriere method showed the highest AUC in both female and male cohorts. The Cameriere method shows a high degree of accuracy at the age threshold of 14 years. To adopt the Cameriere method to estimate the 14-year age threshold more accurately, however, it is suggested - according to the Youden index - that the decision criterion be set at the lower value of 12.928 for females and 13.258 years for males, obtaining a sensitivity of 85% and specificity of 88% in females, and a sensitivity of 77% and specificity of 92% in males. If a specificity level >90% is needed, the cut-off point should be set at 12.959 years (82% sensitivity) for females. © The Author(s) 2015.

The aims of this study were (a) to identify and compare the speed and agility of 12- and 14-year-old elite male basketball players and (b) to investigate relations between speed and agility for both age groups of basketball players, to help coaches to improve their work. Sixty-four players aged 12 (M = 11.98 years, SD = 0.311) and 54 players aged 14 (M = 14.092 years, SD = 0.275) were tested. Three agility tests: agility t-test, zigzag agility drill, and agility run 4 × 15 m and 3 speed tests: 20-m run, 30-m run, and 50-m run were applied. Fourteen-year-old players achieved significantly better results in all speed and agility tests compared with 12-year-old players. The correlation coefficient (r = 0.81, p = 0.001) showed that 12-year-old players have the same ability in the 30- and 50-m runs. The other correlation coefficient (r = 0.59, p = 0.001) indicated that 20- and 30-m runs had inherently different qualities. The correlation coefficients between agility tests were <0.71, and therefore, each test in this group represents a specific task. In 14-year-old players, the correlation coefficients between the speed test results were <0.71. In contrast, the correlation coefficients between the agility tests were >0.71, which means that all the 3 tests represent the same quality. During the speed training of 12-year-old players, it is advisable to focus on shorter running distances, up to 30 m. During the agility training of the same players, it is useful to apply exercises with various complexities. In speed training of the 14-year-old players, the 30- and 50-m runs should be applied, and agility training should include more specific basketball movements and activities.

We report human serum levels of selected persistent organic pollutants (POPs) categorized by age, sex, and race/ ethnicity from a statistically representative sampling of the U.S. population during 2003 and 2004. The serum levels are for several chemicals listed in the Stockholm Convention on Persistent Organic Pollutants, in the Geneva Convention on Long-Range Transboundary Air Pollution, or in both. Population data for each chemical are described by geometric means and percentiles and are categorized by age, sex, and race/ ethnicity. At the 90th and 95th percentile, the dioxin total toxic equivalency (TEQ), using the 2005 toxic equivalency factors (TEFs) for all persons 12 years of age and older was 30.9 pg/g lipid (95% confidence interval (CI): 28.2-33.9 pg/g lipid) and 37.8 pg/g lipid (95% CI: 35.3-43.4 pg/g lipid), respectively. At both the 90th and 95th percentiles total TEQ increased significantly with increasing age. The population geometric mean (GM) for the total PCB concentration (sum of 35 congeners) for all persons 12 years of age and older was 0.820 ng/g whole-weight (95% CI: 0.782-0.863 ng/g whole-weight) and 134.4 ng/g lipid (95% CI: 128.9-140.0 ng/g lipid). The population 95th percentile for the total PCB concentration for all persons 12 years of age and older was 3.53 ng/g whole-weight (95% CI: 3.23-3.92 ng/g whole-weight) and 531 ng/g lipid (95% CI: 498-570 ng/g lipid).

Performance assessment has become an invaluable component of monitoring player development and within talent identification programs in soccer, yet limited performance data are available for female soccer players across a wide age range. The aim of this study was to describe the physical performance characteristics of female soccer players ranging in age from 12 to 21 years. High-level female soccer players (n=414) were evaluated on linear sprinting (36.6 m with 9.1 m splits), countermovement jump (CMJ), and two agility tests. Separate one-way ANOVAs were used to compare performance characteristics between (1) each year of chronological age and (2) three age groups: 12-13 years, n=78, 14-17 years, n=223, and 18-21 years, n=113. Mean linear sprint speed over 9.1 m was similar across all chronological ages, however sprint speed over the final 9.1 m, CMJ height and agility scores improved until approximately 15-16 years. Outcomes from the group data indicated better performance on all tests for the 14-17-year-old group compared with the 12-13-year-old group. Additionally, sprint speed on the second and fourth 9.1 m splits and 36.6 m sprint speed as well as performance on the Illinois agility test was better in the 18-21-year-old group compared with the 14-17-year-old group. The findings from this study indicate that marked improvements of high intensity short duration work occur up until 15-16 years. Smaller gains in performance were observed beyond 16 years of age as evidenced by better performance on 36.6 m sprint speed, several sprint splits and the Illinois agility test in the college aged players (i.e., 18-21-year-old group). © 2010 John Wiley & Sons A/S.

The aim of this study was to investigate the factors associated with short sleep duration on southern Brazilian high school students. Our study was comprised of 1,132 adolescents aged 14 to 19 years, enrolled in public high schools in São José, Brazil. The students answered a questionnaire about working (work and workload), health perception, smoking, school schedule, sleep (duration and daytime sleepiness), and socio-demographics data. The results showed that more than two thirds of adolescent workers had short sleep duration (76.7%), and those with a higher workload (more than 20 hours) had a shorter sleep duration (7.07 hours) compared to non-workers (7.83 hours). In the analysis of factors associated with short sleep duration, adolescents who worked (OR = 2.12, 95% CI 1.53 to 2.95) were more likely to have short sleep duration compared to those who did not work. In addition, older adolescents (17-19 years) and students with poor sleep quality were 40% and 55% more likely to have short sleep duration compared to younger adolescents (14-16 years) and students with good sleep quality, respectively. Adolescents with daytime sleepiness were more likely to have short sleep duration (OR = 1.49, 95% CI 1.06 to 2.07) compared to those without excessive daytime sleepiness. In addition students of the morning shift (OR = 6.02, 95% CI 4.23 to 8.57) and evening shift (OR = 2.16, 95% CI 1.45 to 3.22) were more likely to have short sleep duration compared to adolescents of the afternoon shift. Thereby adolescents who are workers, older, attended morning and evening classes and have excessive daytime sleepiness showed risk factors for short sleep duration. In this sense, it is pointed out the importance of raising awareness of these risk factors for short sleep duration of students from public schools from São José, located in southern Brazil.

Healthy Together Victoria (HTV) - a complex 'whole of system' intervention, including an embedded cluster randomized control trial, to reduce chronic disease by addressing risk factors (physical inactivity, poor diet quality, smoking and harmful alcohol use) among children and adults in selected communities in Victoria, Australia (Healthy Together Communities). To describe the methodology for: 1) assessing changes in the prevalence of measured childhood obesity and associated risks between primary and secondary school students in HTV communities, compared with comparison communities; and 2) assessing community-level system changes that influence childhood obesity in HTC and comparison communities. Twenty-four geographically bounded areas were randomized to either prevention or comparison (2012). A repeat cross-sectional study utilising opt-out consent will collect objectively measured height, weight, waist and self-reported behavioral data among primary [Grade 4 (aged 9-10y) and Grade 6 (aged 11-12y)] and secondary [Grade 8 (aged 13-14y) and Grade 10 (aged 15-16y)] school students (2014 to 2018). Relationships between measured childhood obesity and system causes, as defined in the Foresight obesity systems map, will be assessed using a range of routine and customised data. This research methodology describes the beginnings of a state-wide childhood obesity monitoring system that can evolve to regularly inform progress on reducing obesity, and situate these changes in the context of broader community-level system change.

The purpose of this study was to examine associations between (a) self-reported reasons for and contexts of alcohol use and (b) high-intensity drinking (i.e., having 10+ drinks in a row in the past 2 weeks) among national samples of U.S. 12th grade students. Data were obtained from 16,902 students who reported any past 12-month alcohol use from nationally representative annual 12th grade student samples from 2005-2016. When asked about drinking behavior during the past 2 weeks, 72% reported consuming less than 5 drinks at most during 1 drinking occasion; 14% reported 5-9 drinks, 7% reported 10-14 drinks, and 7% reported 15+ drinks. Adolescent drinkers in all categories (<5, 5-9, 10-14, and 15+ drinks) endorsed "to have a good time" as the most prevalent reason for alcohol use, and "at a party" as the most prevalent context of alcohol use. However, high-intensity drinking was particularly likely among adolescents drinking for coping, compulsive use, and drug effect reasons, as well as those who enjoyed the taste. Having 15+ drinks (vs. 10-14 drinks) was particularly associated with compulsive use and enjoying the taste. The relative risk of any high-intensity drinking, and of higher levels of high-intensity drinking involvement, increased with the total number of reasons and contexts endorsed. Alcohol appears to serve a larger number of functions for high-intensity drinking adolescents than non-high-intensity drinking youth. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The purpose of the current in-vivo study was to assess the effect of using 0.12% chlorhexidine (CHX) mouth rinse, before bonding, on shear bond strength of polycarbonate brackets bonded with composite adhesive. Eighteen orthodontic patients with a mean age 21.41 ± 1.2 years, who were scheduled to have 2 or more first premolars extracted, were included in this study. Patients were referred for an oral prophylaxis program which included, in part, the use of a mouth rinse. Patients were divided into 2 groups, a test group of 9 patients who used 0.12% CHX gluconate mouth rinse twice daily and a control group of 9 patients who used a mouth rinse without CHX, but with same color. After 1 week, polycarbonate brackets were bonded to first premolars with Transbond XT composite adhesive. Premolars were extracted after 28 days and tested for shear bond strength on a universal testing machine. Student's t-test was used to compare shear bond strengths of both groups. No statistically significant difference was found in bond strengths' values between both groups. The test group (with CHX) has mean shear bond strength of 14.21 ± 2.42 MPa whereas the control group (without CHX) revealed a mean strength of 14.52 ± 2.31 MPa. The use of 0.12% CHX mouth rinse, for one week before bonding, did not affect the shear bond strength of polycarbonate brackets bonded with Transbond composite. Furthermore, these brackets showed clinically acceptable bond strength.

This study investigated the clinical characteristics of internet addiction using a cross-sectional survey and psychiatric interview. A structured questionnaire consisted of demographics, Symptom Checklist 90, Self-Rating Anxiety Scale, Self-Rating Depression Scale, and Young's Internet Addiction Test (YIAT) was administered to students of two secondary schools in Wuhan, China. Students with a score of 5 or higher on the YIAT were classified as having Internet Addiction Disorder (IAD). Two psychiatrists interviewed students with IAD to confirm the diagnosis and evaluate their clinical characteristics. Of a total of 1076 respondents (mean age 15.4 ± 1.7 years; 54.1% boys), 12.6% (n = 136) met the YIAT criteria for IAD. Clinical interviews ascertained the Internet addiction of 136 pupils and also identified 20 students (14.7% of IAD group) with comorbid psychiatric disorders. Results from multinomial logistic regression indicated that being male, in grade 7-9, poor relationship between parents and higher self-reported depression scores were significantly associated with the diagnosis of IAD. These results advance our understanding of the clinical characteristics of Internet addiction in Chinese secondary school students and may help clinicians, teachers, and other stakeholders better manage this increasingly serious mental condition. © 2014 The Authors.

Throughout the United States, over 70% of public schools with 12th grade offer school-sponsored work (SSW) programs for credit; 60% offer job-shadowing programs for students. Wisconsin offers a variety of work-based learning programs for students, including, but not limited to, job shadowing, internships, co-op education, and youth apprenticeship programs. No research has compared workplace injury and school-based behaviors in students enrolled in SSW programs who work only 1 job compared with those who work multiple jobs. A total of 6810 students in the 5 public health regions in Wisconsin responded to an anonymous questionnaire that was administered in 2003. The questionnaire asked about employment, injury, characteristics of injury, and school-based behaviors and performance. A total of 3411 high school students aged 14 to 18 reported they were employed during the school year. Among the working students, 13.5% were enrolled in a SSW program. Of the SSW students, 44% worked multiple jobs. SSW students who worked multiple jobs were more likely to do hazardous job tasks, to work after 11 PM, to work over 40 hours per week, to have a near-miss incident, to have a coworker injured, and to be injured at work. SSW students who are working multiple jobs are violating labor laws that put their safety and their school performance at risk. The responsibilities of employers and schools have to be addressed to ensure that SSW students are abiding by labor laws when working multiple jobs.

Adolescents are known to have high risk factors for sleep disorders, yet the youth rates of sleep disturbances are unknown. This study aimed to determine the prevalence of sleep disorders among New Zealand high school students. The Auckland Sleep Questionnaire (ASQ) was administered to high school students at six schools in the North Island. Schools were chosen to reflect a range of ethnicities and school deciles, which identify the socioeconomic status of households in the school catchment area. A total of 1388 students completed the ASQ. The median age was 17 years (range 14-23) and females represented 43.5% (n=604) of the total group. A total of 37.2% of the students surveyed reported having significant sleep symptoms lasting longer than one month. Depression and anxiety were present in 51.7% and 44.8% of students reporting a sleep problem, respectively. A moderate correlation was observed between sleep problems and depression (r=0.34, p<0.01), and sleep problems and anxiety (r=0.31, p<0.01). Problem alcohol use and other substance use were more common in students with sleep symptoms (12.2% and 5.5% respectively). No difference was found in the rate of sleep problems reported by different ethnic groups. A considerable proportion of students surveyed reported significant sleep symptoms. This study has the potential to aid physicians within New Zealand in better appreciating the burden of sleep disorders faced by young people and in effectively assessing and managing different causes of sleep symptoms in this demographic.

Despite increased use of zebrafish (Danio rerio) in biomedical research, consistent information regarding appropriate euthanasia methods, particularly for embryos, is sparse. Current literature indicates that rapid cooling is an effective method of euthanasia for adult zebrafish, yet consistent guidelines regarding zebrafish younger than 6 mo are unavailable. This study was performed to distinguish the age at which rapid cooling is an effective method of euthanasia for zebrafish and the exposure times necessary to reliably euthanize zebrafish using this method. Zebrafish at 3, 4, 7, 14, 16, 19, 21, 28, 60, and 90 d postfertilization (dpf) were placed into an ice water bath for 5, 10, 30, 45, or 60 min (n = 12 to 40 per group). In addition, zebrafish were placed in ice water for 12 h (age ≤14 dpf) or 30 s (age ≥14 dpf). After rapid cooling, fish were transferred to a recovery tank and the number of fish alive at 1, 4, and 12-24 h after removal from ice water was documented. Euthanasia was defined as a failure when evidence of recovery was observed at any point after removal from ice water. Results showed that younger fish required prolonged exposure to rapid cooling for effective euthanasia, with the required exposure time decreasing as fish age. Although younger fish required long exposure times, animals became immobilized immediately upon exposure to the cold water, and behavioral indicators of pain or distress rarely occurred. We conclude that zebrafish 14 dpf and younger require as long as 12 h, those 16 to 28 dpf of age require 5 min, and those older than 28 dpf require 30 s minimal exposure to rapid cooling for reliable euthanasia.

The TWEAK–Fn14 dyad is involved in age-associated pathological changes in skeletal muscle

Tajrishi, Marjan M.; Sato, Shuichi; Shin, Jonghyun

Highlights: • The levels of TWEAK receptor Fn14 are increased in skeletal muscle during aging. • Deletion of Fn14 attenuates age-associated skeletal muscle fiber atrophy. • Deletion of Fn14 inhibits proteolysis in skeletal muscle during aging. • TWEAK–Fn14 signaling activates transcription factor NF-κB in aging skeletal muscle. • TWEAK–Fn14 dyad is involved in age-associated fibrosis in skeletal muscle. - Abstract: Progressive loss of skeletal muscle mass and strength (sarcopenia) is a major clinical problem in the elderly. Recently, proinflammatory cytokine TWEAK and its receptor Fn14 were identified as key mediators of muscle wasting in various catabolic states. However, the rolemore » of the TWEAK–Fn14 pathway in pathological changes in skeletal muscle during aging remains unknown. In this study, we demonstrate that the levels of Fn14 are increased in skeletal muscle of 18-month old (aged) mice compared with adult mice. Genetic ablation of Fn14 significantly increased the levels of specific muscle proteins and blunted the age-associated fiber atrophy in mice. While gene expression of two prominent muscle-specific E3 ubiquitin ligases MAFBx and MuRF1 remained comparable, levels of ubiquitinated proteins and the expression of autophagy-related molecule Atg12 were significantly reduced in Fn14-knockout (KO) mice compared with wild-type mice during aging. Ablation of Fn14 significantly diminished the DNA-binding activity of transcription factor nuclear factor-kappa B (NF-κB), gene expression of various inflammatory molecules, and interstitial fibrosis in skeletal muscle of aged mice. Collectively, our study suggests that the TWEAK–Fn14 signaling axis contributes to age-associated muscle atrophy and fibrosis potentially through its local activation of proteolytic systems and inflammatory pathways.« less

1987-01-01

A survey of knowledge, attitude, and practices regarding human reproduction and sexuality was undertaken in 2 groups of secondary school students in Chile to assess whether greater knowledge of reproduction and sexuality is associated with greater permissiveness and earlier initiation of sexual activity. Students in 2 public schools, 1 coeducational and 1 for female students only, were of lower middle class background, while students at the coeducational private school were of higher socioeconomic status. An anonymous, semiclosed questionnaire was administered to students in the 3 schools. The schools were selected because their directors agreed to permit the study. 14.8% of the 351 public school students were aged 14 or under and 77.8% were 15-18, while 99.5% of the 197 private school students were aged 15-18. The students' levels of knowledge of human reproduction and sexuality were measured through direct personal assessments by the students themselves and through 21 questions to confirm the assessments. At least 93% of students in all schools said their level of knowledge was medium or high, but the test indicated that only 64% of public school students and 75% of private school students actually had medium or high levels of knowledge. 45.9% of private and 27.9% of public school students felt the information they received from their schools about sexuality was adequate, while 41.9% of private and 60.9% of public school students felt it was insufficient. There were no significant differences in the opinions of the 2 groups of students concerning premarital sex, but the reasons given by the private school students to explain their attitudes expressed a greater sense of commitment to the partner, while those of the public school students tended to be more functional. Among public school students, 38.7% of males and 9.7% of females reported having had sexual relations, while among private school students, 17.7% of males and 4.4% of females reported having done so. No significant differences were reported in the age of initiating sexual activity in the 2 groups. Students in the school with the highest overall level of knowledge of human reproduction and sexuality had lower overall levels of sexual activity.

2015-09-28

It has been shown that food insecurity is associated with poor diet quality and unfavourable health outcomes. However, little is known about the potential effects of food insecurity on the overall malnutrition status among children. In this study, we investigated the prevalence of food insecurity among 1583 elementary school students, aged 6-14 years, living in Chinese rural areas and examined its association with four malnutrition signs, including rickets sequelae, anaemia, stunting and wasting. Information on food security was collected via questionnaires. Rickets sequelae were assessed by an experienced paediatrician during the interview. Anaemia was determined by the WHO Hb thresholds adjusted by the local altitude. Weight and height were measured during the interview. Stunting and wasting were then evaluated according to WHO child growth standards (2007). We examined the association between food insecurity and the number of malnutrition signs (total number = 4), and the likelihood of having severe malnutrition (presence of 3+ signs), after adjusting for potential confounders, such as age, social-economic status and dietary intakes. During the previous 12 months, the overall prevalence of food insecurity was 6.1% in the entire studied population and 16.3% in participants with severe malnutrition. Participants with food insecurity had a slightly higher number of malnutrition signs (1.14 v. 0.96; P=0.043) relative to those who were food secure, after adjusting for potential confounders. Food insecurity was also associated with increased likelihood of having severe malnutrition (adjusted OR 3.08; 95% CI 1.47, 6.46; P=0.003). In conclusion, food insecurity is significantly associated with malnutrition among Chinese children in this community.

Radium-226 dose to a boy from playing on mill tailings

DOE Office of Scientific and Technical Information (OSTI.GOV)

Mays, C.W.; Lucas, H.F.; Lloyd, R.D.

Two boys born in September 1949 played on uranium mill tailings from about ages 8 to 12. One of these boys was diagnosed as having leukemia at age 15.5. The 226Ra body burden of the survivor was measured at age 38. The whole-body 226Ra content measured by counting in vivo was 0 {plus minus} 17 Bq and independently by Rn breath analysis as 4.3 {plus minus} 2.1 Bq. At the same time, a control subject with no known exposure to 226Ra, matched in age, height, and weight, was also measured. The whole-body content was estimated as 4 {plus minus} 15more » Bq and independently by Rn breath analysis as 5.5 {plus minus} 3.7 Bq. The body burden of the control subject was not significantly different from that of the exposed person. The radiation dose to the marrow-free skeleton assuming a constant 226Ra:Ca ratio since birth was 0.49 and 1.33 mGy at ages 14 and 38, respectively. The radiation dose to the marrow-free skeleton assuming 226Ra intake only between ages 8 to 12 was 1.4 and 2.8 mGy at ages 14 and 38, respectively. The best estimate is the mean of these two estimates: 0.9 and 2.1 mGy at ages 14 and 38, respectively. The alpha-particle dose to the red marrow from 226Ra and its decay products was 0.05 mGy at age 14 and 0.10 mGy at age 38. Since no excess was found for the radium dial painters whose doses were much higher, the induction of leukemia by doses of this magnitude would seem quite unlikely.« less

Objectives: The aim of this study was to assess the distribution of chronotypes in a sample of Iraqi Kurdish medical students. Methods: A descriptive cross-sectional study was conducted at the Hawler Medical University College of Medicine in Erbil City, Iraq, between 1st January and 31st March 2013. A total of 580 students were given the reduced version of the Horne and Ostberg Morningness-Eveningness Questionnaire (MEQr), a close-ended self-administered questionnaire. Results: Of the 580 students, 130 (22.4%) were male and 450 (77.6%) were female. The mean age ± standard deviation was 20.3 ± 1.45 years, with a range of 17–24 years. Most of the students (52.6%) were in the intermediate class, followed by morning type (24.1%) and evening type (23.3%). Significant gender differences were detected in the proportion of morning, intermediate and evening types (P <0.001). The mean scores for the female students were 14.8 ± 2.2 and the mean scores for the male students were 14.6 ± 7.3, with no statistically significant differences (P = 0.45). Conclusion: Students in the College of Medicine were mostly classified as intermediate types. The morning type was more common among this student population, particularly male students, than has been reported in similar age groups in some Western countries. There was a significant gender difference in the proportion of MEQr types. PMID:25097771

Objective To determine the nutritional status and prevalence of malnutrition and overweight in students in rural schools and their relationship with school absence rates. Methods Descriptive study carried out in 34 rural schools in Anapoima and La Mesa in 2013. A sample of 785 (82.4 %) students was selected by convenience sampling. The inclusion criteria were students registered for the period 2013 in grades 0-5 (ages 5-16) with parental consent and student assent. Weight and height of all subjects were taken. Overall absence rates and illness-related absence rates were recorded. Results 422 pupils were male (53.8 %) and 524 (66.8 %) had between 5-9 years old. A lower than average height for age occurred in 10.1 %(n=79) of the students. The thinness was recorded at 1.75 %(n=13), the overweight at 14.3 %(n=112) and the obesity at 4.5 %(n=45) of the students. The number of absence episodes per child per year due to any reason and due to disease was 5.7 and 1.4, respectively. Stunted growth and overweight students had a significantly higher number of absence days compared to students with adequate nutritional status (p <0.01). Stunted growth had the highest absence rates. Conclusions Malnutrition and obesity coexist in the study area. There is a significant relationship between school absence days (both general and illness-related) and stunting and overweight in students.

Many risk behaviours in adolescence are socially patterned. However, it is unclear to what extent socioeconomic position (SEP) influences adolescent drinking in various parts of Europe. We examined how alcohol consumption is associated with parental SEP and adolescents' own SEP among students aged 14-17 years. Cross-sectional data were collected in the 2013 SILNE study. Participants were 8705 students aged 14-17 years from 6 European cities. The dependent variable was weekly binge drinking. Main independent variables were parental SEP (parental education level and family affluence) and adolescents' own SEP (student weekly income and academic achievement). Multilevel Poisson regression models with robust variance and random intercept were fitted to estimate the association between adolescent drinking and SEP. Prevalence of weekly binge drinking was 4.2% (95%CI = 3.8-4.6). Weekly binge drinking was not associated with parental education or family affluence. However, weekly binge drinking was less prevalent in adolescents with high academic achievement than those with low achievement (PR = 0.34; 95%CI = 0.14-0.87), and more prevalent in adolescents with >€50 weekly income compared to those with ≤€5/week (PR = 3.14; 95%CI = 2.23-4.42). These associations were found to vary according to country, but not according to gender or age group. Across the six European cities, adolescent drinking was associated with adolescents' own SEP, but not with parental SEP. Socio-economic inequalities in adolescent drinking seem to stem from adolescents' own situation rather than that of their family.

Study Objective To examine associations between age at initiation of prescription stimulants and illicit use and abuse of prescription stimulants, alcohol, and other drugs among college students in the United States. Design Web-based survey of college students. Setting A large (full-time undergraduate population > 20,000) university. Intervention A Web-based survey was sent to a random sample of 5389 undergraduate college students plus an additional 1530 undergraduate college students of various ethnic backgrounds over a 2-month period. Measurements and Main Results Alcohol abuse was assessed by including a modified version of the Cut Down, Annoyance, Guilt, Eye-opener (CAGE) instrument. Drug use–related problems were assessed with a slightly modified version of the Drug Abuse Screening Test, short form (DAST-10). The final sample consisted of 4580 undergraduate students (66% response rate). For the analyses, five subgroups were created based on age at initiation of prescription stimulant use: no prescription stimulant use, grades kindergarten (K)–4, grades 5–8, grades 9–12, and college. Undergraduate students to whom stimulants were prescribed in grades K–4 reported similar rates of alcohol and other drug use compared with that of the group that had no prescription stimulant use. For example, students who started prescription stimulants in grades K–4 were no more likely to report coingestion of alcohol and illicit prescription stimulants (odds ratio [OR] 1.4, 95% confidence interval [CI] 0.2–11.5, NS] than the group that had no prescription stimulant use. However, undergraduate students whose prescription stimulant use began in college had significantly higher rates of alcohol and other drug use. For example, students who started a prescription stimulant in college were almost 4 times as likely (OR 3.7, 95% CI 1.9–7.1, p < 0.001) to report at least three positive indicators of drug abuse on the DAST-10 compared with the group that had no prescription stimulant use. Conclusions In concordance with results of previous research, these results indicate that initiation of prescription stimulants during childhood is not associated with increased future use of alcohol and other drugs.

Purpose: To evaluate refractive errors in school age children with color vision deficiency (CVD) and those with normal color vision (NCV) in order to make a better understanding of the emmetropization process. Methods: A total of 4,400 primary school students aged 7–12 years were screened for color vision using Ishihara pseudoisochromatic color vision plate sets. Of these, 160 (3.6%) students had CVD. A total of 400 age- and sex-matched students with NCV were selected as controls. Refractive status was evaluated using objective cyclorefraction. Results: The CVD group included 136 male (85%) and 24 female (15%) subjects with mean age of 10.1 ± 1.8 years. The NCV group comprised of 336 male (84%) and 64 female (16%) subjects with mean age of 10.5 ± 1.2 years. The prevalence of myopia (7.7% vs. 13.9%, P < 0.001) and hyperopia (41% vs. 57.4%, P = 0.03) was significantly lower in the CVD group. Furthermore, subjects with CVD subjects demonstrated a lower magnitude of refractive errors as compared to the CVD group (mean refractive error: +0.54 ± 0.19 D versus + 0.74 ± 1.12 D, P < 0.001). Conclusion: Although the lower prevalence of myopia in subjects with CVD group supports the role of longitudinal chromatic aberration in the development of refractive errors; the lower prevalence of hyperopia in this group is an opposing finding. Myopia is a multifactorial disorder and longitudinal chromatic aberration is not the only factor influencing the emmetropization process. PMID:25709775

2016-09-01

The aim of the study was to determine the incidence of intestinal parasitic diseases (IPD) and associated factors in primary school students and to assess the knowledge and practices of mothers about these diseases. This is a cross-sectional study carried out in January-March 2014 in 471 students aged 5-11 years, studying at 3 schools randomly selected from the city centre regions with different socioeconomic levels. Stratified sampling method was used in the present study and the data were collected in two stages. In the first stage, parents were informed about the study and pre-prepared questionnaire forms were used to collect the data about the students and parents. In the second stage, laboratory analyses of collected stool samples were performed. The total prevalence of IPD was 18.3%, it was higher in the primary school located in a region with a lower socioeconomic level compared to other two schools (27.6% vs. 14.4%, and 10%, respectively). Most commonly detected parasite was E. vermicularis (12.1%). The prevalence of IPD was not associated with the classroom, gender, number of siblings, and the use of purified drinking water at home, while it was found to decrease with the increasing maternal education level. The maternal knowledge level score was 12.01±4.29 vs. 13.41±3.94 in students with and without IPD, respectively. With regard to the methods used to treat IPD, 23% of the mothers reported that they are using conventional methods. The health education programmes about the associated risk factors are of great importance for early detection and treatment of childhood parasitic infections.

This study assessed students' attitudes toward science in Qatar. A cross-sectional, nationwide probability sample representing all students enrolled in grades 3 through 12 in the various types of schools in Qatar completed the 'Arabic Speaking Students' Attitudes toward Science Survey' (ASSASS). The validity and reliability of the 32-item instrument, encompassing five sub-scales, have already been shown to be robust. The present analysis focused on responses from 1978 participants representing the students who completed the ASSASS in Arabic. Descriptive statistics were computed and a competing pair of multiple indicators multiple causes models is presented that attempt to link patterns in students' responses to the ASSASS with a set of indicators. The final model retained student age, gender, nationality (i.e. Qatari vs. Non-Qatari Arab), and school type as indicators. Findings from this study suggest that participants' attitudes toward science decrease with age, and that these attitudes and related preferences are influenced by students' nationality and the type of school they attend. Equally important, the often-reported advantages for male over female precollege students in terms of attitudes toward science were much less prominent in the present study.

To assess the effectiveness of a positive youth development (PYD)-based sports mentorship program on the physical and mental well-being of adolescents recruited in a community setting. This is a randomized controlled trial in which we recruited students from 12 secondary schools in Hong Kong, China. Participants were randomly assigned in a 1:1 ratio to an intervention or a control arm after stratification for school from October 2013 to June 2014. Participants were not blinded to allocation because of the nature of the intervention. Students in the intervention arm received an after-school, PYD-based sports mentorship for 18 weeks. Each weekly session lasted 90 minutes. Students in the control arm received exclusive access to a health education Web site. Six hundred and sixty-four students (mean age 12.3 years [SD 0.76]; 386 girls [58.1%]) completed baseline and postintervention assessments. The intervention improved students' mental well-being (Cohen's d , 0.25; 95% confidence interval [CI], 0.10 to 0.40; P = .001), self-efficacy (Cohen's d , 0.22; 95% CI, 0.07 to 0.37; P = .01), resilience (Cohen's d , 0.19; 95% CI, 0.03 to 0.34; P = .02), physical fitness (flexibility [Cohen's d , 0.28; 95% CI, 0.13 to 0.43; P = .02], lower limb muscle strength [Cohen's d , 0.18; 95% CI, 0.03 to 0.33; P = .03], and dynamic balance [Cohen's d , 0.21; 95% CI, 0.06 to 0.37; P = .01]), and physical activity levels (Cohen's d , 0.39; 95% CI, 0.24 to 0.55; P < .0001). The intervention did not significantly improve physical well-being (Cohen's d , -0.01; 95% CI, -0.17 to 0.14; P = .86), BMI z scores (Cohen's d , -0.03; 95% CI, -0.18 to 0.12; P = .69), body fat proportion (Cohen's d , -0.15; 95% CI, -0.31 to 0.00; P = .051), and social connectedness (Cohen's d , -0.03; 95% CI, -0.18 to 0.12; P = .72). A PYD-based sports mentorship intervention improved healthy adolescents' mental well-being, psychological assets, physical fitness, and physical activity levels.

The purpose of the present study was to estimate the prevalence of depression in Chinese university students, and to identify the socio-demographic factors associated with depression in this population. A multi-stage stratified sampling procedure was used to select university students (N = 5245) in Harbin (Heilongjiang Province, Northeastern China), who were aged 16–35 years. The Beck Depression Inventory (BDI) was used to determine depressive symptoms of the participants. BDI scores of 14 or higher were categorized as depressive for logistic regression analysis. Depression was diagnosed by the Structured Clinical Interview (SCID) for the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV). 11.7% of the participants had a BDI score 14 or higher. Major Depressive Disorder was seen in 4.0% of Chinese university students. There were no statistical differences in the incidence of depression when gender, ethnicity, and university classification were analyzed. Multivariate analysis showed that age, study year, satisfaction with major, family income situation, parental relationship and mother's education were significantly associated with depression. Moderate depression is prevalent in Chinese university students. The students who were older, dissatisfied with their major, had a lower family income, poor parental relationships, and a lower level of mother's education were susceptible to depression.

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.

The reliability and construct validity of three age-adapted-intensity Yo-Yo tests were evaluated in untrained (n = 67) vs. soccer-trained (n = 65) 9- to 16-year-old schoolgirls. Tests were performed 7 days apart for reliability (9- to 11-year-old: Yo-Yo intermittent recovery level 1 children's test; 12- to 13-yearold: Yo-Yo intermittent endurance level 1; and 14- to 16-year-old: Yo-Yo intermittent endurance level 2). Yo-Yo distance covered was 40% (776 ± 324 vs. 556 ± 156 m), 85% (1252 ± 484 vs. 675 ± 252 m) and 138% (674 ± 336 vs. 283 ± 66 m) greater (p ≤ .010) for the soccer-trained than for the untrained girls aged 9-11, 12-13 and 14-16 years, respectively. Typical errors of measurement for Yo-Yo distance covered, expressed as a percentage of the coefficient of variation (confidence limits), were 10.1% (8.1-13.7%), 11.0% (8.6-15.4%) and 11.6% (9.2-16.1%) for soccer players, and 11.5% (9.1-15.8%), 14.1% (11.0-19.8%) and 10.6% (8.5-14.2%) for untrained girls, aged 9-11, 12-13 and 14-16, respectively. Intraclass correlation coefficient values for test-retest were excellent (0.795-0.973) in both groups. No significant differences were observed in relative exercise peak heart rate (%HRpeak) between groups during test and retest. The Yo-Yo tests are reliable for determining intermittent-exercise capacity and %HRpeak for soccer players and untrained 9- to 16-year-old girls. They also possess construct validity with better performances for soccer players compared with untrained age-matched girls, despite similar %HRpeak.

The Age-Varying Association of Student Status with Excessive Alcohol Use: Ages 18 to 30 Years.

2017-02-01

There is a well-known link between attending college and engaging in excessive alcohol use. This study examines in a national sample how the association between student status and excessive alcohol use changes from late adolescence through young adulthood and whether the association of student status with excessive alcohol use is different for students residing with versus away from parents during the school year. This study used cross-sectional data from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of noninstitutionalized civilian adults residing in the United States. Our analyses included nonhigh school young adults who were ages 18 to 30 years (n = 8,645). Excessive alcohol use included past-year (i) high-intensity drinking (men: ≥10 standard drinks; women: ≥8) and (ii) exceeding weekly drinking guidelines (men: >14 drinks per week; women: >7). Students who resided away from their parents and students who lived with their parents during the school year were compared to nonstudents. Analyses using time-varying effect modeling showed that the relationship of student status with excessive alcohol use varied as a function of age. Overall student status lost its association with excessive alcohol use in the early 20s, after controlling for demographics and other adult social roles. The association between student status and excessive alcohol use also varied considerably across age and depending on whether the student was residing with or away from parents. The association of student status with excessive alcohol use is heterogeneous in terms of both age and living arrangements, suggesting opportunities for interventions targeting problematic alcohol use. Future research should examine additional sources of heterogeneity of students in their risk for excessive alcohol use. Copyright © 2016 by the Research Society on Alcoholism.

Are Parenting Practices Associated with the Development of Narcissism? Findings from a Longitudinal Study of Mexican-origin Youth

Wetzel, Eunike; Robins, Richard W.

2016-01-01

Narcissism is an important and consequential aspect of personality, yet we know little about its developmental origins. Using data from a longitudinal study of 674 Mexican-origin families, we examined cross-lagged relations between parenting behaviors (warmth, hostility, monitoring) and narcissism (superiority, exploitativeness). Parental hostility at age 12 was associated with higher levels of exploitativeness at age 14, whereas parental monitoring at age 12 was associated with lower levels of exploitativeness at age 14. These effects replicated across three different parenting measures: child reports, spouse reports, and behavioral coding of parent-child interactions. None of the parenting dimensions was related to superiority, suggesting that parenting practices are more strongly related to the maladaptive than the adaptive component of narcissism. PMID:28042186

A community-wide school health project for the promotion of smoke-free homes was launched in June 2010 with the aim of promoting the benefits of smoke-free homes to all school-aged children (aged 6-18), and indirectly to their parents and family members. The 1-year project included health talks on a smoke-free life; the distribution of educational leaflets; slogan and visual art competitions; and a health fair held in June 2011. Two sets of questionnaires were developed to solicit a resolution and action from the participants regarding the establishment of a smoke-free home, and their decision to stay smoke-free. This is a paper to report on the activities of this project, the attempts to reach out to school-aged children, and their indications of agreement with, support for, and commitment to promoting smoke-free homes. The project reached an estimated 12,800 school-aged children in Hong Kong. A large proportion of those received educational leaflets (69.6-88.2 %). Of those who participated in the health fair, 69.7-87.6 % agreed to promote the concept of smoke-free homes to friends and family. More primary than secondary students pledged to not take up smoking (90.8 vs 85.8 %). About 82 % of those who had experimented with smoking pledged to stop. A small proportion of them reported already having established a smoke-free policy at home (14.9 %), placed a 'No Smoking' sign at home (16.4 %), informed visitors of their smoke-free policy at home (12.9 %), and asked visitors to dispose of lit cigarettes before entering their home (15.9 %). This community-wide school health project on the benefits of smoke-free homes reached a large number of students, and indirectly to family members, and home visitors. Public health efforts of this kind should be continued to reach younger generations and the general public.

Characteristics of self-harm differ across ages, but there is little work identifying age-related differences in younger people. Young people entering adolescence face emotionally and developmentally different challenges to those entering adulthood. This study investigates how Emergency Department (ED) presentations and management of self-harm differ through adolescence and early adulthood. 3782 consecutive self-harm episodes involving 2559 people aged 12-25 years were identified from an existing database of Leeds ED attendances from 2004 to 2007. Odds ratios for each of four age bands were compared to the remaining young people. The female to male ratio was 6.3:1 at 12-14 years old, decreasing with successive age groups to 1.2:1 at 22-25 years old. Self-poisoning was commoner in those under 18 years old. 18-25 year olds were more likely to self-poison with prescribed medications, mixed overdoses, alcohol or recreational drugs. 18-25 year olds more often required medical treatment for the effects of the self-harm. 12-14 year olds were more often seen urgently by ED medical staff and offered high intensity mental health aftercare. Repetition of self-harm was commonest in 12-14 year olds, although multiple repetition of self-harm was commonest in 22-25 year olds. Data were not collected on whether the aftercare offered was received. The study sample included hospital attenders only. The large excess of females over males in young people's self-harm is only true at the younger age range. Older adolescents present with more severe acts of self-harm, yet receive the lowest intensity of assessment and after care. Copyright © 2016 Elsevier B.V. All rights reserved.

2017-01-01

The aim of the study was to examine how psychological stress changes over time in young and middle-aged patients after experiencing an acute myocardial infarction (AMI) and whether these changes differ between men and women. We analyzed data obtained from 2358 women and 1151 men aged 18 to 55 years hospitalized for AMI. Psychological stress was measured using the 14-item Perceived Stress Scale (PSS-14) at initial hospitalization and at 1 month and 12 months after AMI. We used linear mixed-effects models to examine changes in PSS-14 scores over time and sex differences in these changes, while adjusting for patient characteristics and accounting for correlation among repeated observations within patients. Overall, patients' perceived stress decreased over time, especially during the first month after AMI. Women had higher levels of perceived stress than men throughout the 12-month period (difference in PSS-14 score = 3.63, 95% confidence interval = 3.08 to 4.18, p < .001), but they did not differ in how stress changed over time. Adjustment for patient characteristics did not alter the overall pattern of sex difference in changes of perceived stress over time other than attenuating the magnitude of sex difference in PSS-14 score (difference between women and men = 1.74, 95% confidence interval = 1.32 to 2.16, p < .001). The magnitude of sex differences in perceived stress was similar in patients with versus without post-AMI angina, even though patients with angina experienced less improvement in PSS-14 score than those without angina. In young and middle-aged patients with AMI, women reported higher levels of perceived stress than men throughout the first 12 months of recovery. However, women and men had a similar pattern in how perceived stress changed over time.

To investigate the nutritional status of school-age children in rural area in Hunan, China from 2012 to 2015 and to evaluate the effectiveness of the "Nutrition Improvement Program for Compulsory Education Students in Rural Area" (hereinafter referred to as "Nutrition Improvement Program"). The nutritional status of school-age children aged 6-14 years was evaluated after the implementation of the "Nutrition Improvement Program" and the changing trend of the children's nutritional status was analyzed. The statistical analysis was performed on the monitoring data of the school-age children aged 6-14 years in rural area in Hunan, China from 2012 to 2015, which came from "The Nutrition and Health Status Monitoring and Evaluation System of Nutrition Improvement Program for Compulsory Education Students in Rural Area". In 2015, female students aged 6-7 years in rural area in Hunan, China had a significantly greater body length than the rural average in China (P<0.05). However, the other age groups had significantly smaller body length and weight than the rural averages in China (P<0.05). After the implementation of "Nutrition Improvement Program", the prevalence rate of growth retardation decreased (P<0.05), but the prevalence rate of emaciation increased (P<0.05). At the same time, the prevalence rate of overweight/obesity increased (P<0.05) and the prevalence rate of anemia decreased (P<0.05). The implementation of "Nutrition Improvement Program" has achieved some success, but the nutritional status of school-age children has not improved significantly. Overweight/obesity and malnutrition are still present. Therefore, to promote the nutritional status of school-age children it is recommended to improve the measures for the "Nutrition Improvement Program".

The aim was to determine the distribution and associated factors of accommodative amplitude (AA) in six- to 12-year-old children and compare the results with those calculated using Hofstetter's formula. In a cross-sectional study in 2015, random sampling was done from urban and rural populations of Shahroud, northern Iran. Participating schoolchildren were examined for manifest, cycloplegic and subjective refraction, as well as uncorrected vision and visual acuity. The AA was measured with Donders' push-up method using a ruler. The near point of convergence (NPC) was also measured. Of the 6,624 selected children, 5,620 participated in the study and after applying the exclusion criteria, the final analyses were done on data from 5,444 schoolchildren. The mean age of the final sample was 9.24 ± 1.71 years (from six to 12 years) and 53.6 per cent (n = 2,919) were boys. Mean measured AA was 14.44 D (95 per cent confidence interval [CI]: 14.33-14.55). In all age groups, the mean measured AA was less than the predicted mean value calculated with the Hofstetter's equation. Mean measured AA was 14.44 D (95 per cent CI: 14.28-14.59) and 14.45 D (95 per cent CI: 14.29-14.6) in boys and girls, respectively (p = 0.926). AA significantly declined with age (coefficient: -0.18, 95 per cent CI: -0.23 to -0.12, p < 0.001). Mean AA in emmetropic, myopic and hyperopic children was 14.31 D, 17.30 D and 14.87 D, respectively. Older age (coefficient = -0.18), living in rural areas (coefficient = -0.48) and NPC (coefficient = 0.47) inversely related with AA and higher AA was associated with a shift of the spherical equivalent refraction toward myopia (coefficient = -0.41). The differences among groups with different types of refractive error and high AA in children with myopia are important findings of this study. The results of the present study suggest that Hofstetter's formula provides inaccurate AA estimates in children and thus, the interpretation of this index requires further population-based studies in different racial and ethnic groups. © 2017 Optometry Australia.

Stronger vection in junior high school children than in adults

PubMed Central

Shirai, Nobu; Imura, Tomoko; Tamura, Rio; Seno, Takeharu

2014-01-01

Previous studies have shown that even elementary school-aged children (7 and 11 years old) experience visually induced perception of illusory self-motion (vection) (Lepecq et al., 1995, Perception, 24, 435–449) and that children of a similar age (mean age = 9.2 years) experience more rapid and stronger vection than do adults (Shirai et al., 2012, Perception, 41, 1399–1402). These findings imply that although elementary school-aged children experience vection, this ability is subject to further development. To examine the subsequent development of vection, we compared junior high school students' (N = 11, mean age = 14.4 years) and adults' (N = 10, mean age = 22.2 years) experiences of vection. Junior high school students reported significantly stronger vection than did adults, suggesting that the perceptual experience of junior high school students differs from that of adults with regard to vection and that this ability undergoes gradual changes over a relatively long period of development.

2017-03-01

Background Three successive editions of the International Classification of Headache Disorders and multiple guideline papers on headache care have described evidence based diagnosis and treatment of headache disorders. It remains unknown, however, to which extent this has improved the diagnosis and management of headache. That was the aim of our study in which we also analysed differences between three social groups in Russia. Methods We studied 1042 students (719 females, 323 males, mean age 20.6, age range 17-40), 1075 workers (146 females, 929 males, mean age 40.4, age range 21-67) and 1007 blood donors (484 females, 523 males, mean age 34.1, age range 18-64). We conducted a semi-structured, validated, face-to-face professional interview. Data on prevalence and associated factors have previously been published. A section of the interview focused on previous diagnosis and treatment, the topic of this paper. Results Only 496 of 2110 participants (23%) with headache in Russia had consulted because of headache. Students consulted more frequently (35%), workers and blood donors less often (13% and 14%). Only 12% of the patients with ICHD-3beta diagnosis of migraine and 11.7% with ICHD-3beta diagnosis of tension-type headache (TTH) had previously been correctly diagnosed. Triptans were used by only 6% of migraine patients. Only 0.4% of migraine patients and no TTH patients had received prophylactic treatment. Conclusion Despite existing guidelines about diagnosis and treatment, both remain poor in Russia. According to the literature this is only slightly better in Europe and America. Dissemination of existing knowledge should have higher priority in the future.

2013-03-01

Determination of family dysfunction predictors in adolescent students of Cartagena, Colombia. A cross-sectional analytical research was conducted by means of a probabilistic sample per conglomerate of high-school students. Participation of students between 13 and 17 years was requested. Family dysfunction was identified through the family APGAR scale. Predictors were adjusted by binary logistic regression. A total of 1,730 students agreed to participate, mean age was 14.7 years (SD=1.2), and 52.7% were girls. The family APGAR scale showed a Cronbach alpha of 0.78. A group of 896 students (51.8%) reported family dysfunction. Predictors of family dysfunction were: clinically significant depressive symptoms (OR=3.61; IC 95%: 2.31-5.63), low religiosity (OR=1.73; CI 95%: 1.41-2.13), non-nuclear family (OR=1.71, CI 95% 1.71-2.09) (OR=1.73, 95% CI 1.41-2.13), non-nuclear family (OR=1.71, 95%: CI 1.41-2.09), consumption of any illegal substance in their lives (OR=1.67, CI 95%: 1.15-2.13), residents of depressed neighborhoods (OR = 1.49; CI 95%: 1.19-1.87), and poor academic performance (OR=1.43; CI 95%: 1.15-1.76). Clinically significant depressive symptoms, low religiosity and non-nuclear family are the main predictors of family dysfunction among adolescent students in Cartagena, Colombia. The association is possibly bidirectional. Copyright © 2013 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

Previous studies suggest that student athletes may be less likely than nonathletes to engage in sexual behavior. However, few have explored sexual risk behavior among athletes in early adolescence. In 2005, a sample of 10,487 students in 26 Los Angeles public middle and high schools completed a self-administered survey that asked about their demographic characteristics, sports participation, sexual behaviors and expectations, and parental relationships. Chi-square analyses compared reported levels of daily participation in sports, experience with intercourse, experience with oral sex and condom use at last intercourse by selected characteristics. Predictors of sexual experience and condom use were assessed in multivariate logistic regression analyses. One-third of students reported daily participation in sports. This group had higher odds of ever having had intercourse and ever having had oral sex than their peers who did not play a sport daily (odds ratios, 1.2 and 1.1, respectively). The increases in risk were greater for middle school sports participants than for their high school counterparts (1.5 and 1.6, respectively). Among sexually experienced students, daily sports participants also had elevated odds of reporting condom use at last intercourse (1.4). Students as young as middle school age who participate in sports daily may have an elevated risk for STDs and pregnancy. Health professionals should counsel middle school athletes about sexual risk reduction, given that young students may find it particularly difficult to obtain contraceptives, STD testing and prevention counseling.

The purpose of this study was to examine the test-retest reliability and construct validity of three age-adapted Yo-Yo intermittent tests in football players aged 9-16 years (n = 70) and in age-matched non-sports active boys (n = 72). Within 7 days, each participant performed two repetitions of an age-related intensity-adapted Yo-Yo intermittent test, i.e. the Yo-Yo intermittent recovery level 1 children's test for 9- to 11-year-olds; the Yo-Yo intermittent endurance level 1 for 12- to 13-year-olds and the Yo-Yo intermittent endurance level 2 test for 14- to 16-year-olds. Peak heart rate (HRpeak) was determined for all tests. The distance covered in the tests was 57% (1098 ± 680 vs. 700 ± 272 m), 119% (2325 ± 778 vs. 1062 ± 285 m) and 238% (1743 ± 460 vs. 515 ± 113 m) higher (p ≤ .016), respectively for football-trained than for non-sports active boys aged 9-11, 12-13 and 14-16 years. The typical errors of measurement for Yo-Yo distance, expressed as a percentage of the coefficient of variation (confidence interval), were 11.1% (9.0-14.7%), 10.1% (8.1-13.7%) and 8.5% (6.7-11.7%) for football players aged 9-11, 12-13 and 14-16 years, respectively, with corresponding values of 9.3% (7.4-12.8%), 10.2% (8.1-14.0%) and 8.5% (6.8-11.3%) for non-sports active boys. Intraclass correlation coefficient values for test-retest were excellent in both groups (range: 0.844-0.981). Relative HRpeak did not differ significantly between the groups in test and retest. In conclusion, Yo-Yo intermittent test performances and HRpeak are reliable for 9- to 16-year-old footballers and non-sports active boys. Additionally, performances of the three Yo-Yo tests were seemingly better for football-trained than for non-sports active boys, providing evidence of construct validity.

Schools have been identified as an important place in which to support adolescent emotional health, although evidence as to which interventions are effective remains limited. Relatively little is known about student and staff views regarding current school-based emotional health provision and what they would like to see in the future, and this is what this study explored. A random sample of 296 English secondary schools were surveyed to quantify current level of emotional health provision. Qualitative student focus groups (27 groups, 154 students aged 12-14) and staff interviews (12 interviews, 15 individuals) were conducted in eight schools, purposively sampled from the survey respondents to ensure a range of emotional health activity, free school meal eligibility and location. Data were analysed thematically, following a constant comparison approach. Emergent themes were grouped into three areas in which participants felt schools did or could intervene: emotional health in the curriculum, support for those in distress, and the physical and psychosocial environment. Little time was spent teaching about emotional health in the curriculum, and most staff and students wanted more. Opportunities to explore emotions in other curriculum subjects were valued. All schools provided some support for students experiencing emotional distress, but the type and quality varied a great deal. Students wanted an increase in school-based help sources that were confidential, available to all and sympathetic, and were concerned that accessing support should not lead to stigma. Finally, staff and students emphasised the need to consider the whole school environment in order to address sources of distress such as bullying and teacher-student relationships, but also to increase activities that enhanced emotional health. Staff and students identified several ways in which schools can improve their support of adolescent emotional health, both within and outside the curriculum. However, such changes should be introduced as part of a wider consideration of how the whole school environment can be more supportive of students' emotional health. Clearer guidance at policy level, more rigorous evaluation of current interventions, and greater dissemination of good practice is necessary to ensure adolescents' emotional health needs are addressed effectively within schools.

Perceived Medical School stress of undergraduate medical students predicts academic performance: an observational study.

Medical students are exposed to high amounts of stress. Stress and poor academic performance can become part of a vicious circle. In order to counteract this circularity, it seems important to better understand the relationship between stress and performance during medical education. The most widespread stress questionnaire designed for use in Medical School is the "Perceived Medical School Stress Instrument" (PMSS). It addresses a wide range of stressors, including workload, competition, social isolation and financial worries. Our aim was to examine the relation between the perceived Medical School stress of undergraduate medical students and academic performance. We measured Medical School stress using the PMSS at two different time points (at the end of freshman year and at the end of sophomore year) and matched stress scores together with age and gender to the first medical examination (M1) grade of the students (n = 456). PMSS scores from 2 and 14 months before M1 proved to be significant predictors for medical students' M1 grade. Age and gender also predict academic performance, making older female students with high stress scores a potential risk group for entering the vicious circle of stress and poor academic performance. PMSS sum scores 2 and 14 months before the M1 exam seem to have an independent predictive validity for medical students' M1 grade. More research is needed to identify potential confounders.

Coincidence-anticipation timing requirements are different in racket sports.

2012-10-01

The aim of this study was to compare the coincidence-anticipation timing accuracy of athletes of different racket sports with various stimulus velocity requirements. Ninety players (15 girls, 15 boys for each sport) from tennis (M age = 12.4 yr., SD = 1.4), badminton (M age = 12.5 yr., SD = 1.4), and table tennis (M age = 12.4 yr., SD = 1.2) participated in this study. Three different stimulus velocities, low, moderate, and high, were used to simulate the velocity requirements of these racket sports. Tennis players had higher accuracy when they performed under the low stimulus velocity compared to badminton and table tennis players. Badminton players performed better under the moderate speed comparing to tennis and table tennis players. Table tennis players had better performance than tennis and badminton players under the high stimulus velocity. Therefore, visual and motor systems of players from different racket sports may adapt to a stimulus velocity in coincidence-anticipation timing, which is specific to each type of racket sports.

Developmental changes in parent-child communication throughout adolescence.

PubMed

Keijsers, Loes; Poulin, François

2013-12-01

This study examined how parent-child communication regarding adolescent unsupervised activities develops over the course of adolescence. We used questionnaire data from 390 adolescents (58% girls; 90% European Canadian) who were followed from age 12 to 19. Latent growth curve modeling revealed curvilinear developmental changes that differed for boys and girls. From age 14 to 19 (but not from age 12 to 14) a linear decrease in parental control was found for both genders. For girls, parent-child communication decreased in early adolescence, as indicated by decreasing parental solicitation, decreasing adolescent disclosure, and increasing secrecy. Girls' communication with parents intensified in middle adolescence, as indicated by increasing parental solicitation, increasing adolescent disclosure, and decreasing adolescent secrecy. For boys, disclosure declined in early adolescence, but secrecy and solicitation were stable throughout adolescence. Parental knowledge decreased from age 12 to 19 for both genders but was temporarily stable for middle adolescent girls. The meaning of these developmental changes, their timing, and gender differences are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

[Natural evolution of excess body weight (overweight and obesity) in children].

2013-11-01

To analyze the chronological evolution of excess body weight (overweight and obesity) in order to raise public awareness within the different areas of intervention (family, school, business environment, health services) and to take effective actions. Weight, height and body mass index (BMI) of 604 healthy subjects (307 males and 297 females) have been recorded at birth and at the age of 1, 2, 3, 4, 6, 8, 10, 12 and 14 years. The excess body weight has been calculated according to national references from Ferrández et al. Prevalence of excess body weight at age 14 years was significantly higher (P<.05) in males (29%) than in females (12.8%). BMI (kg/m2) was significantly higher (P<.05) for both sexes in every age period, except for birth and age 1 year, in those patients with excess body weight at age 14, with respect to patients with normal nutritional status of the same age. Those groups with excess body weight at age 14 showed a BMI (Z-score) reaching overweight or obesity levels at age 4, and progressively increasing. Excess body weight probably starts at early stages in life, when dietary habits of the child depends almost exclusively on family habits, and may be aggravated during school attendance. Finally, a disproportionate weight increase occurs in adolescence that is probably related to unhealthy dietary habits and way of life. Copyright © 2013 Asociación Española de Pediatría.
