Sizes of horizontal wear facets of maxillary anterior teeth were studied longitudinally from the primary dentition at age five to the young adult dentition at the age of 18 years. By a planimetric method, we calculated the wear areas on dental casts taken at the ages of five, ten, 14, and 18 years from the dentition of 39 healthy, orthodontically untreated subjects with good morphological occlusion. For young adults, we also studied the association between the amount of wear and reported parafunctions, maximal bite force, salivary buffer capacity, salivary flow rate, and some cephalometric variables. Size of wear facets on all anterior teeth increased with age. Significant correlations were found between the total wear areas of the six anterior primary teeth at five years of age and those of their permanent successors at age 14 (r = 0.44) and 18 (r = 0.39). For an individual, tooth wear at five years of age was, however, of low predictive value for tooth wear in young adulthood, whereas tooth wear at 14 years of age predicted it well (r = 0.89). Highest correlations between tooth wear and background factors at 18 years of age were found for maximal anterior bite force (r = 0.44) and for the size of the gonial angle (r = -0.31). Wear of anterior teeth was not associated with reported parafunctions in young adulthood.

Immunogenicity and safety of the human papillomavirus (HPV)-16/18 AS04-adjuvanted vaccine were evaluated in healthy Chinese females aged 9–45 years in 2 phase IIIB, randomized, controlled trials. Girls aged 9–17 years (ClinicalTrials.gov, NCT00996125) received vaccine (n = 374) or control (n = 376) and women aged 26–45 years (NCT01277042) received vaccine (n = 606) or control (n = 606) at months 0, 1, and 6. The primary objective was to show non-inferiority of anti-HPV-16 and -18 immune responses in initially seronegative subjects at month 7, compared with Chinese women aged 18–25 years enrolled in a separate phase II/III trial (NCT00779766). Secondary objectives were to describe the anti-HPV-16 and -18 immune response, reactogenicity and safety. At month 7, immune responses were non-inferior for girls (9–17 years) vs. young women (18–25 years): the upper limit of the 95% confidence interval (CI) for the geometric mean titer (GMT) ratio (women/girls) was below the limit of 2 for both anti-HPV-16 (0.37 [95% CI: 0.32, 0.43]) and anti-HPV-18 (0.42 [0.36, 0.49]). Immune responses at month 7 were also non-inferior for 26–45 year-old women vs. 18–25 year-old women: the upper limit of the 95% CI for the difference in seroconversion (18–25 minus 26–45) was below the limit of 5% for both anti-HPV-16 (0.00% [–1.53, 1.10]) and anti-HPV-18 (0.21% [–1.36, 1.68]). GMTs were 2- to 3-fold higher in girls (9–17 years) as compared with young women (18–25 years). The HPV-16/18 AS04-adjuvanted vaccine had an acceptable safety profile when administered to healthy Chinese females aged 9–45 years. PMID:25424785

The study reported here examined the developmental antecedents of conservative versus liberal ideologies using data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development and a follow-up study conducted when the sample was 18 years old. Specifically, we examined variation in conservative versus liberal ideologies at age 18 years as a function of parenting attitudes and child temperament during the first 5 years of life. Consistent with long-standing theories on the development of political attitudes, our results showed that parents' authoritarian attitudes assessed when children were 1 month old predicted conservative attitudes in those children more than 17 years later. Consistent with the findings of Block and Block (2006), our results also showed that early childhood temperament predicted variation in conservative versus liberal ideologies.

To estimate differences in skeletal maturity and stature from birth to age 18 years between individuals who are overweight vs normal weight in young adulthood. Weight, length and height, and relative skeletal age (skeletal-chronological age) were assessed annually from birth to age 18 years in 521 subjects (255 women) in the Fels Longitudinal Study who were overweight or obese (body mass index (BMI) >25 kg m(-2), n=131) or normal weight (n=390) in young adulthood (18-30 years). Generalized estimating equations were used to test for skeletal maturity and stature differences by young adult BMI status. Differences in height increased during puberty, being significant for girls at ages 10 to 12 years, and for boys at ages 11 to 13 years (P-values<0.001), with overweight or obese adults being ∼3 cm taller at those ages than normal weight adults. These differences then diminished so that by age 18 years, overweight or obese adults were not significantly different in stature to their normal weight peers. Differences in skeletal maturity were similar, but more pervasive; overweight or obese adults were more skeletally advanced throughout childhood. Skeletal maturity differences peaked at chronological age 12 in boys and 14 in girls (P-values<0.001), with overweight or obese adults being ∼1 year more advanced than normal weight adults. This descriptive study is the first to track advanced skeletal maturity and linear growth acceleration throughout infancy, childhood and adolescence in individuals who become overweight, showing that differences occur primarily around the time of the pubertal growth spurt. Increased BMI in children on a path to becoming overweight adults precedes an advancement in skeletal development and subsequently tall stature during puberty. Further work is required to assess the predictive value of accelerated pubertal height growth for assessing obesity risk in a variety of populations.

Sunburn and sun protective behaviors among adults aged 18-29 years--United States, 2000-2010.

PubMed

2012-05-11

Skin cancer is an important public health concern. Nonmelanoma skin cancers, comprised mainly of basal cell carcinoma and squamous cell carcinoma, are the most common malignancies in the United States. Melanoma, although less common, is the deadliest form of skin cancer. Both melanoma and nonmelanoma skin cancers can be disfiguring, negatively affect quality of life, and create economic burden. Furthermore, age-adjusted incidence rates of both have increased in recent years. Different patterns of sun exposure are associated with different types of skin cancer. Continuous, chronic sun exposure, such as that observed among outdoor workers is associated with squamous cell carcinoma. Intermittent exposure, such as recreational exposure, is associated with melanoma and basal cell carcinoma. Sunburn typically occurs after intermittent exposure, and the risk for melanoma increases with an increasing number of sunburns during all periods of life. Sunburn is more common among persons aged 18-29 years compared with older adults. To evaluate trends in sunburn and sun protective behaviors among persons aged 18-29 years, CDC and the National Cancer Institute analyzed data from the 2000, 2003, 2005, 2008, and 2010 National Health Interview Survey (NHIS). The results indicated that although protective behaviors such as sunscreen use, shade use, and wearing long clothing to the ankles have increased in recent years, sunburn prevalence remains high, with 50.1% of all adults and 65.6% of whites aged 18-29 years reporting at least one sunburn in the past 12 months. These results suggest that additional efforts are needed to identify and implement effective strategies targeting younger adults to improve their sun protective behaviors and prevent sunburn and ultimately skin cancer.

To describe the intake of fruit and vegetables among employed migrant population aged 18 to 59 year-olds in China. Data from the Migrant Population Survey related to China Chronic Disease and Risk Factor Surveillance that conducted in 170 counties/districts in 31 provinces, 2012, was used. Information on non-communicable diseases and related risk factors among migrant population were collected through face-to-face questionnaire interview, physical measurement and lab tests. A total of 48 704 subjects aged 18 to 59 years old were included in our study. Sample was standardized by age and sex. Information on average daily fruit and vegetables intake, prevalence of low fruit and vegetables intake, grouped by sex, age, industries, and education level were analyzed. The average daily intakes of vegetables and fruits were 353.7 (95%CI:351.3-356.2) g and 125.1 (95%CI:123.4-126.9) g respectively, among the employed migrant population aged 18-59 years old in China. Prevalence of low fruit and vegetables intake was 44.1% (95% CI:43.5%-44.6% ) among employed migrant population, 46.2% (95% CI: 45.5%-47.0%)for males and 41.2% (95% CI:40.3%-42.0%)for females (χ(2) = 82.19, P < 0.05). Among different professions, the prevalence of low fruit and vegetables intake was the highest among people working in accommodation and restaurants (46.2%, 95%CI:45.0%-47.3%) while the lowest seen among those working in social services (42.5%, 95%CI:41.4%-43.7%,χ(2) = 15.81, P < 0.05). The prevalence of low fruit and vegetables intake showed a decrease along with the increase of education levels (χ(2) = 22.29, P < 0.05). In 2012, more than 40% of the employed migrant population aged 18 to 59 years old in China had low fruit and vegetables intake. Being male and with low education level were risk factors linked with the higher prevalence of low fruit and vegetables intake.

We characterized post-infancy child growth patterns and determined the incidence of becoming stunted and of recovery from stunting. Data came from Young Lives, a longitudinal study of childhood poverty in four low- and middle-income countries. We analysed length/height measurements for children at ages 1, 5 and 8 years. Children (n 7171) in Ethiopia, India, Peru and Vietnam. Mean height-for-age Z-score (HAZ) at age 1 year ranged from -1·51 (Ethiopia) to -1·08 (Vietnam). From age 1 to 5 years, mean HAZ increased by 0·27 in Ethiopia (P < 0·001) and decreased among the other cohorts (range: -0·19 (Peru) to -0·32 (India); all P < 0·001). From 5 to 8 years, mean HAZ increased in all cohorts (range: 0·19 (India) to 0·38 (Peru); all P < 0·001). Prevalence of stunting (HAZ<-2·0) at 1 year ranged from 21 % (Vietnam) to 46 % (Ethiopia). From age 1 to 5 years, stunting prevalence decreased by 15·1 percentage points in Ethiopia (P < 0·001) and increased in the other cohorts (range: 3·0 percentage points (Vietnam) to 5·3 percentage points (India); all P ≤ 0·001). From 5 to 8 years, stunting prevalence decreased in all cohorts (range: 5·0 percentage points (Vietnam) to 12·7 percentage points (Peru); all P < 0·001). The incidence of becoming stunted between ages 1 to 5 years ranged from 11 % (Vietnam) to 22 % (India); between ages 5 to 8 years, it ranged from 3 % (Peru) to 6 % (India and Ethiopia). The incidence of recovery from stunting between ages 1 and 5 years ranged from 27 % (Vietnam) to 53 % (Ethiopia); between ages 5 and 8 years, it ranged from 30 % (India) to 47 % (Ethiopia). We found substantial recovery from early stunting among children in four low- and middle-income countries.

To understand and analyze the current situation and secular trends for prevalence of malnutrition among Chinese children and adolescents aged 7-18 years from 2005 to 2014, and to provide important scientific basis for students' nutrition improvement. All the subjects aged 7-18 years in both sexes were sampled from 2005, 2010 and 2014 Chinese National Surveys on Students Constitution and Health. According to the new students' health standard of "Screening Standard for Malnutrition of school-age children and adolescents"(WS/T456-2014) in 2014 of China, the nutritional status of children in 31 provinces (autonomous regions and municipalities, excluding Hong Kong, Macao and Taiwan province) were analyzed and compared in different ages, genders, regions and provinces from 2005 to 2014. The Tibetan students was used with the data of Tibetan minority and all the other students from 30 provinces (autonomous regions, municipalities) were Han minority. The prevalence of malnutrition of children and adolescents of Han minority aged 7-18 years in 2014 was 10.0%. The prevalence of malnutrition components, including stunting, mild wasting and moderate severe wasting, were 0.8%, 3.7%, and 5.5%. Compared with 2005 and 2010, the prevalence of malnutrition of Han children and adolescents in 2014 had declined with 5.0 and 2.6 percentage points, respectively, and its components had declined with 1.0, 1.8, 2.2 and 0.4, 1.1, 1.2 percentage points, respectively. The prevalence of malnutrition of 2014 in boys was higher than in girls (11.1% vs.8.9%), the rural was higher than the urban (11.0% vs.9.1%) and the west (11.7%) was higher than the east (9.0%) and the middle (9.2%). Mild wasting of Chinese children and adolescents aged 7-18 years was the main component in malnutrition and the stunting in the Han and Tibetan children and adolescents only accounted for 8.0% and 7.5%, respectively. Compared with 2005 and 2010, the prevalence of malnutrition for Chinese children and adolescents aged

Epilepsy can be one of symptoms of the damage to CNS in children with neurodevelopmental deficits, it is more difficult however to diagnose seizures if they are the first symptom of severe brain damage. This retrospective research was conducted to study causes of symptomatic epilepsy in children aged 3-18 year hospitalized between 2006 and 2007 year in the Department of Pediatric Neurology. 156 children with symptomatic epilepsy occurred after 2 years of life were included. The diagnosis of symptomatic epilepsy was established including clinical picture, neuro-radiological tests and EEG. The information from parents was helpful to analyze the type of seizures. The clinical state of children was analyzed, especially psychomotor development, focal deficits, as well as results of CT and/or MRI, in some children psychological testing was performed, molecular or serological. 156 children with epilepsy were hospitalized, within encephalopathy was diagnosed in 61 children. In 42 children static encephalopathy was associated with birth trauma, in 7 progressive encephalopathy was diagnosed, in 1 child CO intoxication caused encephalopathy, and in 11 cases the cause was not identified. Malformations of nervous system were associated with epilepsy in 37 children, geneticaly determined syndromes in 6, and the head trauma in other 6 children. Disorders of vascular origin caused epilepsy in 16 children, and neuroinfections in 9 children. In 2 children epilepsy was associated with ADEM, and in 11 children nonspecific de/dysmyelination was detected. The brain tumor was detected in 6 children with symptomatic epilepsy. The most common disorder leading to epilepsy in children aged 3-18 years was encephalopathy, within hypoxic-ischemic encephalopathy. The other in sequence were malformations of nervous system and vascular diseases.

Childhood conduct problems are associated with poor functioning in early adulthood. We tested a series of hypotheses to understand the mechanisms underlying this association. We used data from the Environmental Risk (E-Risk) Longitudinal Twin Study, a birth cohort of 2,232 twins born in England and Wales in 1994 and 1995, followed up to age 18 years with 93% retention. Severe conduct problems in childhood were assessed at ages 5, 7, and 10 years using parent and teacher reports. Poor functioning at age 18 years, including cautions and convictions, daily cigarette smoking, heavy drinking, and psychosocial difficulties, was measured through interviews with participants and official crime record searches. Participants 18 years old with versus without a childhood history of severe conduct problems had greater rates of each poor functional outcome, and they were more likely to experience multiple poor outcomes. This association was partly accounted for by concurrent psychopathology in early adulthood, as well as by early familial risk factors, both genetic and environmental. Childhood conduct problems, however, continued to predict poor outcomes at age 18 years after accounting for these explanations. Children with severe conduct problems display poor functioning at age 18 years because of concurrent problems in early adulthood and familial risk factors originating in childhood. However, conduct problems also exert a lasting effect on young people's lives independent of these factors, pointing to early conduct problems as a target for early interventions aimed at preventing poor functional outcomes.

Purpose To evaluate the relationship between unilateral or bilateral criptorchidism, patient age, primary location of the gonad and modality of treatment with testicular volume and hormonal status at 18 years in patients diagnosed and treated for cryptorchidism during childhood. Materials and Methods Testicular volume, LH, FSH, and testosterone were evaluated in 143 young men at 18 years treated in childhood for unilateral (n=103) or bilateral (n=40) cryptorchidism. Results Unilateral cryptorchidism: Location of testis was prescrotal in 36 patients, inguinal in 52 and non-palpable in 15. The mean volume was 9.7 mL compared to 16.2 mL. for the spontaneously descended testicle in unilateral cryptorchidism. However, 22 patients who received HCG had a significantly bigger testis (11.8 mL.) than those treated with primary surgery (9.2 mL). The results showed a significant positive correlation between testicular volume and patient age at treatment. Bilateral cryptorchidism Location of testis was prescrotal in 34 cases, inguinal in 40 and 6 patients with non-palpable testicles. Mean volume at 18 years was 12.9 mL, greater than unilateral cryptorchid testis (9.7 mL) but smaller than healthy contralateral in unilateral cases (16.2 mL). There were significant differences in the testicular growth for bilateral patients with testicular descent after being treated with HCG (14.4 mL) in respect with those untreated (11.1 mL) or those who underwent primary surgery (11.4 mL). There was a significant positive correlation between the testicular volume and palpable (12.4 mL) or non-palpable testis (10.4 mL). There was a correlation between unilateral or bilateral cryptorchidism and levels of FSH. Conclusions Testicular volume and hormonal function at 18 years for patients diagnosed and treated for cryptorchidism during childhood are strongly influenced by whether the undescended testis was unilateral or bilateral. Location of the testes at diagnosis or age of initial treatment exerts

No study has quantified productivity losses associated with breast cancer in younger women aged 18-44 years. This study estimated productivity costs, including work and home productivity losses, among younger women who reported ever receiving a breast cancer diagnosis. A two-part regression model and 2000-2010 National Health Interview Survey data were used to estimate the number of work and home productivity days missed because of breast cancer, adjusted for socioeconomic characteristics and comorbidities. Estimates for younger women were compared with those for women aged 45-64 years. Data were analyzed in 2013-2014. Per capita, younger women with breast cancer had annual losses of $2,293 (95% CI=$1,069, $3,518) from missed work and $442 (95% CI=$161, $723) from missed home productivity. Total annual breast cancer-associated productivity costs for younger women were $344 million (95% CI=$154 million, $535 million). Older women with breast cancer had lower per capita work loss productivity costs of $1,407 (95% CI=$899, $1,915) but higher total work loss productivity costs estimated at $1,072 million (95% CI=$685 million, $1,460 million) than younger women. Younger women with a history of breast cancer face a disproportionate share of work and home productivity losses. Although older women have lower per capita costs, total productivity costs were higher for older women because the number of older women with breast cancer is higher. The results underscore the importance of continued efforts by the public health community to promote and support the unique needs of younger breast cancer survivors. Published by Elsevier Inc.

Although high-grade intraventricular hemorrhage (IVH; grades III-IV) in preterm and low birth weight infants are clearly associated with increased risk of long-term adverse neurodevelopmental sequelae, the impact of low-grade IVH (grades I-II) has been less clear. Some studies have followed these infants through early school age and have shown some conflicting results regarding cognitive outcome. Such studies that assess children at younger ages may not accurately predict outcomes in later childhood, as it is known that fluid and crystallized intelligence peak at age 26 years. There is paucity of data in current medical literature, which correlates low-grade IVH with outcomes in early adulthood. To determine the link between the occurrence of low-grade IVH in low birth weight (birth weight ⩽2500 g) infants born prematurely (gestational age <37 weeks) and intellectual function, academic achievement, and behavioral problems to the age of 18 years. This study is an analysis of data derived from the Infant Health and Development Program (IHDP), a multisite national collaborative study and a randomized controlled trial of education intervention for low birth weight infants from birth until 3 years of age with follow-up through 18 years of age. A total of 985 infants were enrolled in the IHDP. Of the 462 infants tested for IVH, 99 demonstrated sonographic evidence of low-grade IVH, whereas 291 showed no sonographic evidence of IVH. Several outcomes were compared between these two groups. Intelligence was assessed using Stanford-Binet Intelligence scales at age 3 years, Wechsler Intelligence Scale for Children (WISC-III) at age 8 years, Wechsler Abbreviated Scale of Intelligence (WASI) at age 18 years and Woodcock Johnson Tests of Achievement at age 8 and 18 years. Behavior was measured using the Achenbach Behavior Checklist at age 3 years and Child Behavior Checklist (CBCL) at age 8 and 18 years. Outcomes were compared between the IVH-positive and IVH-negative groups

Breast cancer affects women's health-related quality of life negatively, but little is known about how breast cancer affects this in younger women aged 18-44 years. This study measures preference-based health state utility (HSU) values, a scaled index of health-related quality of life for economic evaluation, for younger women with breast cancer and compares these values with same-age women with other cancers and older women (aged ≥45 years) with breast cancer. Data from the 2009 and 2010 Behavioral Risk Factor Surveillance System were analyzed in 2014. The sample included 218,852 women; 7,433 and 18,577 had histories of breast and other cancers. HSU values were estimated using Healthy Days survey questions and a published mapping algorithm. Linear regression models for HSU were estimated by age group (18-44 and ≥45 years). The adjusted breast cancer HSU impact was four times larger for younger women than for older women (-0.097 vs -0.024, p<0.001). For younger women, the effect of breast cancer on HSU was 70% larger than that of other cancers (-0.097 vs -0.057, p=0.024). Younger breast cancer survivors reported lower HSU values than older survivors, highlighting the impact of breast cancer on the physical and mental health of younger women. The estimates may be used to evaluate quality-adjusted life-years or expectancy for prevention or treatment of breast cancer. This study also indicates that separate quality of life adjustments for women by age group are important for economic analysis of public health breast cancer interventions.

Few studies have simultaneously addressed the importance of age of onset and persistence of eczema for the subsequent development of asthma and hay fever, particularly into early adulthood. A high-risk birth cohort was recruited comprising 620 infants, who were then followed up frequently until 2 years of age, annually from age 3 to 7, then at 12 and 18 years, to document any episodes of eczema, current asthma, and hay fever. The generalized estimation equation technique was used to examine asthma and hay fever outcomes at 6 (n = 325), 12 (n = 248) and 18 (n = 240) years, when there was consistency of associations across the follow-ups. Very early-onset persistent (onset <6 months, still present from 2 to 5 years) eczema was related to current asthma (adjusted OR = 3.2 [95% CI = 1.7-6.1]), as was very early-onset remitting eczema (onset <6 months but not present from 2-5 years, OR = 2.7, 95% CI = 1.0-7.2) and early-onset persistent eczema (onset from 6-24 months, OR = 2.3, 95% CI = 1.2-4.7). Late-onset eczema (commenced from 2-5 years) was associated with increased risk of asthma at 12 years (OR = 3.0, 95% CI=1.1-8.2) but not at age 6 years. Only very early-onset persistent eczema was associated with increased risk of hay fever (aOR = 2.4, 95% CI = 1.4-4.1). Eczema which commences in early infancy and persists into toddler years is strongly associated with asthma, and to a lesser extent hay fever, in high-risk children. If these associations are causal, prevention of early-life eczema might reduce the risk of respiratory allergy. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Congenital or early life infection with Toxoplasma gondii has been implicated in schizophrenia aetiology. Childhood cat ownership has been hypothesized as an intermediary marker of T. gondii infection and, by proxy, as a risk factor for later psychosis. Evidence supporting this hypothesis is, however, limited. We used birth cohort data from the Avon Longitudinal Study of Parents and Children (ALSPAC) to investigate whether cat ownership in pregnancy and childhood (ages 4 and 10 years) was associated with psychotic experiences (PEs) in early (age 13, N = 6705) and late (age 18, N = 4676) adolescence, rated from semi-structured interviews. We used logistic regression to examine associations between cat ownership and PEs, adjusting for several sociodemographic and socioeconomic factors, household characteristics and dog ownership. Missing data were handled via multiple imputation. Cat ownership during pregnancy was not associated with PEs at age 13 years [adjusted odds ratio (OR) 1.15, 95% confidence interval (CI) 0.97-1.35] or 18 years (OR 1.08, 95% CI 0.86-1.35). Initial univariable evidence that cat ownership at ages 4 and 10 years was associated with PEs at age 13 years did not persist after multivariable adjustment (4 years: OR 1.18, 95% CI 0.94-1.48; 10 years: OR 1.12, 95% CI 0.92-1.36). There was no evidence that childhood cat ownership was associated with PEs at age 18 years. While pregnant women should continue to avoid handling soiled cat litter, given possible T. gondii exposure, our study strongly indicates that cat ownership in pregnancy or early childhood does not confer an increased risk of later adolescent PEs.

To quantify the relation between prenatal famine exposure and adult mortality, taking into account mediating effects of intermediary life conditions. Historical follow-up study. The Dutch famine (Hunger Winter) of 1944-1945 which occurred towards the end of WWII in occupied Netherlands. From 408,015 Dutch male births born 1944-1947, examined for military service at age 18, we selected for follow-up all men born at the time of the famine in six affected cities in the Western Netherlands (n=25,283), and a sample of unexposed time (n=10,667) and place (n=9087) controls. These men were traced and followed for mortality through the national population and death record systems. All-cause mortality between ages 18 and 63 years using Cox proportional hazards models adjusted for intermediary life conditions. An increase in mortality was seen after famine exposure in early gestation (HR 1.12; 95% confidence interval (CI): 1.01-1.24) but not late gestation (HR 1.04; 95% CI: 0.96-1.13). Among intermediary life conditions at age 18 years, educational level was inversely associated with mortality and mortality was elevated in men with fathers with manual versus non-manual occupations (HR 1.08; CI: 1.02-1.16) and in men who were declared unfit for military service (HR 1.44; CI: 1.31-1.58). Associations of intermediate factors with mortality were independent of famine exposure in early life and associations between prenatal famine exposure and adult mortality were independent of social class and education at age 18. Timing of exposure in relation to the stage of pregnancy may be of critical importance for later health outcomes independent of intermediary life conditions. Copyright © 2013 Elsevier Ltd.

We analyzed the epidemiological data during 1990-2012 that investigated the blood lead level (BLL) in the population aged 0-18 years old in China mainland and provided evidence of the benefits of implementing policies to prevent lead pollution based on the dynamic changes of BLL. Data were collected through databases including China Knowledge Resource Integrated Database (CNKI), CBM disc, Wanfang Data, Pubmed and Medline. The inclusion criteria were: 1. Epidemiological study in healthy population not included studies limited to specific patient; 2. Study subject was not the specific lead exposure population; 3. Sample size should be no less than 100 (for neonatal, no less than 50); 4. BLL detection was under strict quality control; and 5. Results should be presented as BLL (arithmetic mean level or geometric mean level). 62 articles were included in this study. All the surveys in these articles contained 189,352 subjects in 19 provinces, autonomous regions and municipalities. Linear regression analysis showed a significant decrease between 1990 and 2012 with an estimated regression coefficient of 3.05/year (SE=0.01, p<0.001). BLL gradually declined since early 21st century. Median levels of BLL among the three economic zones were 51.4 μg/L in the eastern zone, 52.72 μg/L in the central zone and 46.2 μg/L in the western zone respectively. Median BLLs in male and female population aged 0-18 years old of China were 48.8 μg/L and 46.1μg/L. Median levels of BLL among the different age ranges were 74.9 μg/L in newborn, 46.4 μg/L in 0 to 3 years old, 57.6 μg/L in 3 to 7 years old and 55.6 μg/L in above 7 years old respectively. In conclusion, the BLL in the Chinese population of 0-18 years old has gradually dropped in the past 10 years. The decline in temporal trend still remains under potential impacts of several factors such as economical level, gender and age difference. Although, China has made significant achievements in the control prevention of lead

Approximately 70% of all US suicides are among working-age adults. This study was to determine whether and how 12-month suicidal ideation and suicide attempt were associated with specific occupations among currently employed adults aged 18-64 in the U.S. Data were from 184,300 currently employed adults who participated in the 2008-2013 National Surveys on Drug Use and Health (NSDUH). NSDUH provides nationally representative data on suicidal ideation and suicide attempt. Descriptive analyses and multivariable logistic regressions were conducted. Among currently employed adults aged 18-64 in the U.S., 3.5% had suicidal ideation in the past 12months (3.1% had suicidal ideation only, and 0.4% had suicidal ideation and attempted suicide). Compared with adults in farming, fishing, and forestry occupations (model adjusted prevalence (MAP)=1.6%), adults in the following occupations were 3.0-3.6 times more likely to have suicidal ideation in the past year (model adjusted relative risks (MARRs)=3.0-3.6): lawyers, judges, and legal support workers (MAP=4.8%), social scientists and related workers (MAP=5.4%), and media and communication workers (MAP=5.8%). Among employed adults aged 18-64 in the U.S., the 12-month prevalence of suicidal ideation varies by occupations. Adults in occupations that are at elevated risk for suicidal ideation may warrant focused suicide prevention. Published by Elsevier Inc.

There have been no clinical trials for approval of medications for treating multiple sclerosis in patients younger than age 18 years. All treatments are based on personal experience and data from open observational studies. Fingolimod is an oral drug for multiple sclerosis that has been shown to be efficient and safe in adults. The aim of our study is to describe patients with multiple sclerosis who started treatment with fingolimod before the age of 18 years. Seventeen patients treated with fingolimod were identified in the Brazilian database of children and adolescents with multiple sclerosis. The average time of use of the drug was 8.6 months. Fingolimod showed a good safety and efficacy profile in these patients, all of whom had very active multiple sclerosis. After starting treatment with fingolimod, only one patient had a relapse and a new lesion on magnetic resonance imaging. The patients' degree of disability did not progress. No major adverse events were reported in relation to the first dose of the drug, nor in the short- and medium-term treatment. No patient has been followed for longer than 18 months, thus limiting long-term conclusions. Off-label use of fingolimod in patients younger than age 18 years may be a good therapeutic option for multiple sclerosis control. Copyright © 2015 Elsevier Inc. All rights reserved.

A comparison of folic acid awareness and intake among young women aged 18-24 years.

Hilton, Judith Johnson

2007-10-01

To investigate public understanding of the importance of folic acid intake in young women aged 18-24 years. A written questionnaire designed by the researcher was administered to 138 young women aged 18-24 years attending college or those seeking care in the county health facility. A total of 88 complete questionnaires were used for the data analysis. Young women were not aware of the importance of folic acid, were not taking multivitamins containing folic acid, and were not consuming enough folic acid in their diets. No relationship existed between pregnancy intention and folic acid intake, suggesting that those who were planning a pregnancy in the near future were not consuming adequate amounts of folic acid. A lack of knowledge regarding the importance of folic acid may lead to poor pregnancy outcomes. Many educational opportunities exist and should be developed in clinics, physician's offices, and classes which involve young women in this age group.

Few population-based studies in erectile dysfunction (ED) included subjects less than 40 years old and analyzed the several factors and consequences potentially associated with this condition. Evaluation of the prevalence of erectile dysfunction (ED) and associated factors in a sample of Brazilian men aged 18 to 40 years old. Cross-sectional study in which subjects were contacted in public places of 18 major Brazilian cities and interviewed using an anonymous questionnaire. Survey data were submitted to chi-squared, student's t-test and logistic regression analyses. The data were collected by means of a self-administered questionnaire with 87 questions about sociodemographic variables, general health, habits and lifestyle-related factors, sexual behavior and sexual difficulties, including ED which was assessed by a single question. Prevalence of ED in 1,947 men was 35.0% (73.7% mild, 26.3% moderate/complete). Greater frequency of ED was seen in subjects that never had information about sex, experienced difficulties in the beginning of sexual life and have never masturbated. ED was associated to lower level of education, but not to race, sexual orientation, employment or marital status. Also, no association was found between ED and smoking, alcoholism, obesity, sedentary life, diabetes, hypertension, cardiovascular disease, hyperlipidemia, depression or anxiety. ED caused negative impact in men's self-esteem, interpersonal relationships, work and leisure activities, and in sexual life satisfaction. Less than 10% of men with ED had received medical treatment for this problem. Prevalence of ED in this young population was high, mostly of mild severity. Low education and psychosocial problems were associated to ED and, due probably to the sample subjects' young age, no association was found with organic problems. Measures in the fields of education and psychosocial difficulties prevention would have a positive impact in the control of erectile dysfunction in the young

The present study was undertaken to find out the prevalence of skeletal deformity due to nutritional rickets in children aged 1-18 years in tea garden community in Dibrugarh District of Assam. It was a cross-sectional study and two-stage cluster sampling was used. In the selected tea gardens, all the children aged 1-18 years were screened for skeletal deformity by house-to-house visit. The overall prevalence of skeletal deformity was 2.7 per thousand. Majority of children with deformities (57.27%) were between 7 and 12 years of age. Widening of wrists and ankle was the most frequent symptom (53.8%). Most of the children with deformity had moderate malnutrition (77.27%). Most of the children with skeletal deformity belong to lower (v) (45.45%) grade of Kuppuswamy's grading scale. Bilateral genu valgus deformity (54.54%) and bilateral genu varum (25.92%) deformity were the most common deformities. Widening of wrists and ankle was the most frequent symptom (61.66%). Of the 16,274 tea garden children included in our study (male and female) in the age group 1-18 years, 44 had skeletal deformity due to nutritional rickets. The prevalence of skeletal deformity due to nutritional rickets was found to be 2.7 per thousand children, which are significantly higher when compared with the only other such study, which was on general population in Bangladesh.

This paper discusses patterns of daily smokeless tobacco (SLT) use and correlates of poly SLT use among married women aged 18-40 years in a Mumbai slum community with implications for tobacco control. Using a mixed methods approach, the study included a structured survey with 409 daily SLT users and in-depth interviews with 42 women. Participants for the survey were selected using a systematic sampling procedure (one woman in every fourth eligible household). Univariate and bivariate analysis, and multiple logistic regressions were conducted to identify demographic and social factors associated with women's use of poly SLT products. To illustrate survey results, in-depth interviews were analyzed using Atlas ti software. Sixty-four percent of the women surveyed used only one type of SLT; of these, 30% used mishri, 32% used pan with tobacco and the rest used chewed tobacco (11%), gul (17%) or gutkha (10%). Thirty-six percent used more than one type of SLT. Poly SLT users chewed or rubbed 50% more tobacco as compared to single users (mean consumption of tobacco per day: 9.54 vs. 6.49 grams; p<0.001). Women were more likely to be poly SLT users if they were illiterate as compared to literate (adjusted odds ratio [AOR]=1.67; 95% confidence interval [CI]=1.07-2.71), if they had lived in Mumbai for 10 years or more, versus less than ten years (AOR=1.67, 95% CI=1.03-2.71); and if their husband was a poly SLT user as compared to a non SLT user (AOR=2.78, 95% CI=1.63-4.76). No differences were noted between pregnant and non-pregnant women in SLT consumption patterns. Tobacco control policies and programs must focus specifically on both social context and use patterns to address SLT use among women of reproductive age with special attention to poly SLT users, an understudied and vulnerable population.

Phosphatidylethanol (PEth), as measured in freshly drawn blood samples, could be a promising new biomarker for habitual alcohol consumption, but it is still unknown whether PEth can also be determined from blood samples having been stored frozen for a longer period. PEth 16:0/18:1 and PEth 18:1/18:1 were determined by LC-MS/MS from red blood cells (RBC) derived from blood samples of (I) 20 healthy volunteers (after 1 month of storage at -80 °C) and (II) 232 participants of the population-based European Prospective Investigation into Cancer and Nutrition (EPIC)-Heidelberg study (after 20 years of storage at -196 °C). Analyses involved liquid-liquid extraction from 100 μl aliquots with phosphatidylpropanol (PProp 18:1/18:1) as the internal standard. Extracts were subjected to a 10-min LC gradient separation, using multiple reaction monitoring of deprotonated molecules for quantification. After 1 month of storage at -80 °C, PEth was detectable in all samples at mean concentrations of 393.6 ± 12.4 ng/ml (PEth 16:0/18:1) and 43.3 ± 1.1 ng/ml (PEth 18:1/18:1). In samples stored for 20 years at -196 °C, PEth was detectable in 23.7% of all samples at mean concentrations of 412.2 ± 655.5 ng/ml (PEth 16:0/18:1) and 38.0 ± 74.8 ng/ml (PEth 18:1/18:1). PEth can be determined reliably from samples of moderate habitual alcohol consumers after 1 month of storage at -80 °C. Our data suggest that PEth is generally also detectable in samples after 20 years of storage at -196 °C. Further studies are needed to assess the still unknown impact of storage duration and temperature on different PEth specimen concentrations.

The first aim of the present study was to determine the change in speech recognition in noise over a period of 5 years in participants ages 18 to 70 years at baseline. The second aim was to investigate whether age, gender, educational level, the level of initial speech recognition in noise, and reported chronic conditions were associated with a change in speech recognition in noise. The baseline and 5-year follow-up data of 427 participants with and without hearing impairment participating in the National Longitudinal Study on Hearing (NL-SH) were analyzed. The ability to recognize speech in noise was measured twice with the online National Hearing Test, a digit-triplet speech-in-noise test. Speech-reception-threshold in noise (SRTn) scores were calculated, corresponding to 50% speech intelligibility. Unaided SRTn scores obtained with the same transducer (headphones or loudspeakers) at both test moments were included. Changes in SRTn were calculated as a raw shift (T1 - T0) and an adjusted shift for regression towards the mean. Paired t tests and multivariable linear regression analyses were applied. The mean increase (i.e., deterioration) in SRTn was 0.38-dB signal-to-noise ratio (SNR) over 5 years (p < 0.001). Results of the multivariable regression analyses showed that the age group of 50 to 59 years had a significantly larger deterioration in SRTn compared with the age group of 18 to 39 years (raw shift: beta: 0.64-dB SNR; 95% confidence interval: 0.07-1.22; p = 0.028, adjusted for initial speech recognition level - adjusted shift: beta: 0.82-dB SNR; 95% confidence interval: 0.27-1.34; p = 0.004). Gender, educational level, and the number of chronic conditions were not associated with a change in SRTn over time. No significant differences in increase of SRTn were found between the initial levels of speech recognition (i.e., good, insufficient, or poor) when taking into account the phenomenon regression towards the mean. The study results indicate that hearing

Childhood maltreatment is linked with increased risk for mental illness in adolescence and adulthood. However, little evidence is available on whether different forms of maltreatment have specific effects, and no prospective studies in low- or middle-income countries have addressed this issue. Participants in a population-based, birth cohort study in Pelotas, Brazil (N=3715) self-reported exposure to maltreatment (emotional abuse, physical neglect, physical abuse, sexual abuse, domestic violence) in confidential questionnaires at age 15 years, and were assessed for major depression in interviews at age 18 years, using the MINI. Confounding variables concerning family characteristics were measured in interviews with mothers in the perinatal period and at age 11 years. Females exposed to emotional abuse (OR=2.7; 95%CI=1.9, 3.8) and domestic violence (OR=1.9; 95%CI=1.2, 2.9) were at increased risk for depression after adjustment for confounders and other types of maltreatment. Females exposed to two or more forms of maltreatment were at particularly high risk for depression (OR=4.1; 95%Cl=2.8, 6.1) compared with females not exposed to maltreatment. In adjusted analyses, maltreatment was not associated with depression for males. Detailed information about maltreatment such as timing and frequency was not available, and 1534 individuals were not included in the analyses, who had poorer and less educated mothers. Emotional abuse and domestic violence are strong risk factors for major depression for females. Early intervention to prevent maltreatment and its consequences is critical, especially for girls exposed to poly-maltreatment. Copyright © 2017 The Authors. Published by Elsevier B.V.

Some small studies suggest that maternal postnatal depression is a risk factor for offspring adolescent depression. However, to our knowledge, no large cohort studies have addressed this issue. Furthermore, only 1 small study has examined the association between antenatal depression and later offspring depression. Understanding these associations is important to inform prevention. To investigate the hypothesis that there are independent associations between antenatal and postnatal depression with offspring depression and that the risk pathways are different, such that the risk is moderated by disadvantage (low maternal education) with postnatal depression but not with antenatal depression. Prospective investigation of associations between symptoms of antenatal and postnatal parental depression with offspring depression at age 18 years in a UK community-based birth cohort (Avon Longitudinal Study of Parents and Children) with data from more than 4500 parents and their adolescent offspring. Diagnosis of offspring aged 18 years with major depression using the International Classification of Diseases, 10th Revision. Antenatal depression was an independent risk factor. Offspring were 1.28 times (95% CI, 1.08-1.51; P = .003) more likely to have depression at age 18 years for each standard deviation increase in maternal depression score antenatally, independent of later maternal depression. Postnatal depression was also a risk factor for mothers with low education, with offspring 1.26 times (95% CI, 1.06-1.50; P = .01) more likely to have depression for each standard deviation increase in postnatal depression score. However, for more educated mothers, there was little association (odds ratio, 1.09; 95% CI, 0.88-1.36; P = .42). Analyses found that maternal education moderated the effects of postnatal but not antenatal depression. Paternal depression antenatally was not associated with offspring depression, while postnatally, paternal depression showed a similar pattern to

Gondii infection and, by proxy, as a risk factor for later psychosis. Evidence supporting this hypothesis is, however, limited. Method We used birth cohort data from the Avon Longitudinal Study of Parents and Children (ALSPAC) to investigate whether cat ownership in pregnancy and childhood (4, 10 years old) was associated with psychotic experiences (PEs) in early (age 13; N=6,705) and late (age 18; N=4,676) adolescence, rated from semi-structured interviews. We used logistic regression to examine associations between cat ownership and PEs, adjusting for several sociodemographic and socioeconomic factors, household characteristics and dog ownership. Missing data were handled via multiple imputation. Results Cat ownership during pregnancy was not associated with PEs at age 13 (adjusted odds ratio [OR]: 1.15, 95% confidence interval [CI]: 0.97-1.35) or 18 years (OR: 1.08, 95%CI: 0.86-1.35). Initial univariable evidence that cat ownership at 4 and 10 years was associated with PEs at age 13 years did not persist after multivariable adjustment (4 years OR: 1.18, 95%CI: 0.94-1.48; 10 years OR 1.12, 95%CI: 0.92; 1.36). There was no evidence that childhood cat ownership was associated with PEs at 18 years old. Conclusions While pregnant women should continue to avoid handling soiled cat litter, given possible T Gondii exposure, our study strongly indicates that cat ownership in pregnancy or early childhood does not confer an increased risk of later adolescent PEs.

Low levels of physical activity in childhood are associated with clustering of cardiovascular risk factors (CVRF) as predisposition for atherosclerosis. We assessed the association between sports engagement and age at first myocardial infarction (MI) in a cohort of men under 55 years of age. The Bern percutaneous coronary intervention Registry (NCT 02241291) was analyzed from March 2009 until January 2012. Male patients with first MI, age 18 to 54 years and body mass index ≤25kg/m2 were included. Patients were stratified into two groups based on their starting age with organized sports ≥1 h/week outside school (EARLY: <18, CONTROL: ≥18 years or never). We assessed age at time of first MI, CVRF, and volume of sports training. Of 4,394 consecutive patients, 123 fulfilled the inclusion criteria (EARLY n = 81, CONTROL n = 42). Age at the time of first MI was 3 years younger in the EARLY compared to the CONTROL group (46.8±6.0 vs. 49.8±4.6 years, p = 0.006). Total lifetime training hours, and average yearly training hours, both, before and after age 18, were significantly greater in the EARLY group. Years of training <18 years were weakly inversely correlated with age at first MI (r2 = 0.075, p = 0.002). The proportion of sports-related MI was not different between EARLY and CONTROL (13.6% vs. 11.9%). Patients in the EARLY group had fewer CVRF (2 vs. 3; p = 0.001). Prevalence of smoking was equally high in both groups (63.0% and 64.3%). In our patients aged 54 and younger, the first MI occurred 3 years earlier in those who started regular sports activity before age 18, despite a more active lifestyle and favorable CVRF profile.

Breast cancer in women aged 18-44 years accounts for approximately 27,000 newly diagnosed cases and 3,000 deaths annually. When tumors are diagnosed, they are usually aggressive, resulting in expensive treatment costs. The purpose of this study is to estimate the prevalent medical costs attributable to breast cancer treatment among privately insured younger women. Data from the 2006 MarketScan database representing claims for privately insured younger women were used. Costs for younger breast cancer patients were compared with a matched sample of younger women without breast cancer, overall and for an active treatment subsample. Analyses were conducted in 2013 with medical care costs expressed in 2012 U.S. dollars. Younger women with breast cancer incurred an estimated $19,435 (SE=$415) in additional direct medical care costs per person per year compared with younger women without breast cancer. Outpatient expenditures comprised 94% of the total estimated costs ($18,344 [SE=$396]). Inpatient costs were $43 (SE=$10) higher and prescription drug costs were $1,048 (SE=$64) higher for younger women with breast cancer than in younger women without breast cancer. For women in active treatment, the burden was more than twice as high ($52,542 [SE=$977]). These estimates suggest that breast cancer is a costly illness to treat among younger, privately insured women. This underscores the potential financial vulnerability of women in this age group and the importance of health insurance during this time in life.

Objectives This paper discusses patterns of daily smokeless tobacco (SLT) use and correlates of poly SLT use among married women aged 18–40 years in a Mumbai slum community with implications for tobacco control. Methods Using a mixed methods approach, the study included a structured survey with 409 daily SLT users and in-depth interviews with 42 women. Participants for the survey were selected using a systematic sampling procedure (one woman in every fourth eligible household). Univariate and bivariate analysis, and multiple logistic regressions were conducted to identify demographic and social factors associated with women’s use of poly SLT products. To illustrate survey results, in-depth interviews were analyzed using Atlas ti software. Results Sixty-four percent of the women surveyed used only one type of SLT; of these, 30% used mishri, 32% used pan with tobacco and the rest used chewed tobacco (11%), gul (17%) or gutkha (10%). Thirty-six percent used more than one type of SLT. Poly SLT users chewed or rubbed 50% more tobacco as compared to single users (mean consumption of tobacco per day: 9.54 vs. 6.49 grams; p<0.001). Women were more likely to be poly SLT users if they were illiterate as compared to literate (adjusted odds ratio [AOR]=1.67; 95% confidence interval [CI]=1.07-2.71), if they had lived in Mumbai for 10 years or more, versus less than ten years (AOR=1.67, 95% CI=1.03-2.71); and if their husband was a poly SLT user as compared to a non SLT user (AOR=2.78, 95% CI=1.63-4.76). No differences were noted between pregnant and non-pregnant women in SLT consumption patterns. Conclusions Tobacco control policies and programs must focus specifically on both social context and use patterns to address SLT use among women of reproductive age with special attention to poly SLT users, an understudied and vulnerable population.

Children's Interstitial and Diffuse Lung Disease (chILD) is a heterogeneous group of disorders that is challenging to categorize. In previous study, a classification scheme was successfully applied to children 0 to 2 years of age who underwent lung biopsies for chILD. This classification scheme has not been evaluated in children 2 to 18 years of age. This multicenter interdisciplinary study sought to describe the spectrum of biopsy-proven chILD in North America and to apply a previously reported classification scheme in children 2 to 18 years of age. Mortality and risk factors for mortality were also assessed. Patients 2 to 18 years of age who underwent lung biopsies for diffuse lung disease from 12 North American institutions were included. Demographic and clinical data were collected and described. The lung biopsies were reviewed by pediatric lung pathologists with expertise in diffuse lung disease and were classified by the chILD classification scheme. Logistic regression was used to determine risk factors for mortality. A total of 191 cases were included in the final analysis. Number of biopsies varied by center (5-49 biopsies; mean, 15.8) and by age (2-18 yr; mean, 10.6 yr). The most common classification category in this cohort was Disorders of the Immunocompromised Host (40.8%), and the least common was Disorders of Infancy (4.7%). Immunocompromised patients suffered the highest mortality (52.8%). Additional associations with mortality included mechanical ventilation, worse clinical status at time of biopsy, tachypnea, hemoptysis, and crackles. Pulmonary hypertension was found to be a risk factor for mortality but only in the immunocompetent patients. In patients 2 to 18 years of age who underwent lung biopsies for diffuse lung disease, there were far fewer diagnoses prevalent in infancy and more overlap with adult diagnoses. Immunocompromised patients with diffuse lung disease who underwent lung biopsies had less than 50% survival at time of last follow-up.

This investigation examined differences in functional sit-to-stand power/velocity between cohorts of adults aged 18-97 years. This study included 264 healthy adults classified into four cohorts (18-40, C1; 60-69, C2; 70-79, C2; ≥ 80, C4). Participants completed the sit-to-stand task five times. Power and velocity were measured via the TENDO power analyzer. Absolute average power was maintained from C1-C3, but decreased (p < .01) in C4. Absolute peak power decreased between C1-C2 (p < .01), was similar between C2-C3, and decreased in C4 (p < .01). Relative (to body weight) average and peak power decreased between C1-C2 (p < .01), was similar between C2-C3, and decreased in C4 (p < .01). Average velocity was similar between C1 and C2, but decreased in C3 (p < .01) and C4 (p < .01), respectively. Peak velocity was significantly different between all cohorts (p < .01). Declines in functional power may plateau during the seventh and eighth decades, accelerating after 80 years.

Objective Approximately 70% of all US suicides are among working-age adults. This study was to determine whether and how 12-month suicidal ideation and suicide attempt were associated with specific occupations among currently employed adults aged 18–64 in the U.S. Methods Data were from 184,300 currently employed adults who participated in the 2008–2013 National Surveys on Drug Use and Health (NSDUH). NSDUH provides nationally representative data on suicidal ideation and suicide attempt. Descriptive analyses and multivariable logistic regressions were conducted. Results Among currently employed adults aged 18–64 in the U.S., 3.5% had suicidal ideation in the past 12 months (3.1% had suicidal ideation only, and 0.4% had suicidal ideation and attempted suicide). Compared with adults in farming, fishing, and forestry occupations (model adjusted prevalence (MAP) = 1.6%), adults in the following occupations were 3.0–3.6 times more likely to have suicidal ideation in the past year (model adjusted relative risks (MARRs) = 3.0–3.6): lawyers, judges, and legal support workers (MAP = 4.8%), social scientists and related workers (MAP = 5.4%), and media and communication workers (MAP = 5.8%). Conclusions Among employed adults aged 18–64 in the U.S., the 12-month prevalence of suicidal ideation varies by occupations. Adults in occupations that are at elevated risk for suicidal ideation may warrant focused suicide prevention. PMID:26995251

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.

Background and purpose Hospital costs associated with atrial fibrillation (AFib) among stroke patients have not been well-studied, especially among people younger than 65 years. We estimated the AFib-associated hospital costs in U.S. patients aged 18-64 years. Methods We identified hospital admissions with a primary diagnosis of ischemic stroke from the 2010-2012 MarketScan Commercial Claims and Encounters inpatient datasets, excluding those with capitated health insurance plans, aged <18 or >64, missing geographic region, hospital costs below the 1st or above 99th percentile, and having carotid intervention (N=40,082). We searched the data for AFib and analyzed the costs for non-repeat and repeat stroke admissions separately. We estimated the AFib-associated costs using multivariate regression models controlling for age, sex, geographic region, and Charlson comorbidity index. Results Of the 33,500 non-repeat stroke admissions, 2,407 (7.2%) had AFib. Admissions with AFib cost $4,991 more than those without AFib ($23,770 vs. $18,779). For the 6,582 repeat stroke admissions, 397 (6.0%) had AFib. The costs were $3,260 more for those with AFib than those without ($24,119 vs. $20,929). After controlling for potential confounders, AFib-associated costs for non-repeat stroke admissions were $4,905, representing 20.6% of the total costs for the admissions. Both the hospital costs and the AFib-associated costs were associated with age, but not sex. AFib-associated costs for repeat stroke admissions were not significantly higher than for non-AFib patients, except for those aged 55-64 ($3,537). Conclusions AFib increased the hospital cost of ischemic stroke substantially. Further investigation on AFib-associated costs for repeat stroke admissions is needed. PMID:25851767

Objective: To understand and evaluate the prevalence of myopia and its trend in children and adolescents aged 7-18 years in Han ethnic group in China from 2005 to 2014, and provide evidence for the prevention of myopia. Methods: The data of 2005, 2010 and 2014 Chinese National Students Constitution and Health Surveys were collected. The children and adolescents with complete detection data of binoculus were selected as study subjects. The sample size of three studies were 233 108, 215 319 and 212 743, respectively. The method of curve fitting was used to simulate the myopia detection increase model and analyze the gender and area specific myopia detection increase trends and characteristics from 2005 to 2014. Results: The overall myopia detection rate increased gradually in the children and adolescents aged 7 to 18, which was 47.5 % in 2005, 55.5 % in 2010 and 57.1 % in 2014, respectively. The increase slowed in 2014. A"parabola" shape of myopia detection increase rate was observed. Myopia detection rate increased with age before puberty and decreased with age after puberty gradually. A"cross phenomenon" of myopia detection increase was observed in boys and girls between urban and rural areas. The increase of myopia detection was mainly in urban students before puberty and in rural students after puberty. The age of myopia prevalence peak has become earlier constantly in children and adolescents aged 7-18 years from 2005 to 2014, which was 13 years old in 2005, 12 years old in 2010 and 11 years old in 2014. The increase rate was about 7 % . During 2005-2014, the increase rate of myopia detection gradually increased in younger students and tended to zero in older students. Conclusion: The detection rate of myopia was still high in children and adolescents in China. The age of myopia prevalence peak has become earlier gradually.

A total of 462 schoolgirls aged 7-8 and 17-18 years were examined anthropometrically (45 body measurements and 10 skinfolds) in a cross-sectional study. The data were processed in two age groups: 7-8-year-olds (n = 205) and 17-18-year-olds (n = 257). Relying on average height and weight in the groups, both groups were divided into five body build classes: small, medium, large, pyknomorphous and leptomorphous. In these classes, the differences in all other body measurements were compared, and in both age groups, analogous systematic differences were found in length, width and depth measurements and circumferences. This enabled us to compare proportional changes in body measurements during ten years, using for this ratios of averages of basic measurements and measurement groups in the same body build classes. Statistical analysis by the sign test revealed statistically significant differences between various body build classes in the growth of averages. Girls belonging to the small class differed from the girls of the large class by an essentially greater increase in their measurements. Our results suggest that the growth rate of body measurements of girls with different body build can be studied by the help of body build classification.

In 2014, persons aged 13-29 years represented 23% of the U.S. population, yet accounted for 40% of diagnoses of human immunodeficiency virus (HIV) infection during the same year (1). During 2010-2014, the rates of diagnosis of HIV infection decreased among persons aged 15-19 years, were stable among persons aged 20-24 years, and increased among persons aged 25-29 years (1). However, these 5-year age groups encompass multiple developmental stages and potentially mask trends associated with the rapid psychosocial changes during adolescence through young adulthood. To better understand HIV infection among adolescents aged 13-17 years and young adults aged 18-29 years in the United States and identify ideal ages to target primary HIV prevention efforts, CDC analyzed data from the National HIV Surveillance System (NHSS)* using narrow age groups. During 2010-2014, rates of diagnosis of HIV infection per 100,000 population varied substantially among persons aged 13-15 years (0.7), 16-17 years (4.5), 18-19 years (16.5), and 20-21 years (28.6), and were higher, but less variable, among persons aged 22-23 years (34.0), 24-25 years (33.8), 26-27 years (31.3), and 28-29 years (28.7). In light of the remarkable increase in rates between ages 16-17, 18-19, and 20-21 years, and a recent study revealing that infection precedes diagnosis for young persons by an average of 2.7 years (2), these findings demonstrate the importance of targeting primary prevention efforts to persons aged <18 years and continuing through the period of elevated risk in their mid-twenties.

This observer-blind study compared the prophylactic human papillomavirus (HPV) vaccines, Cervarix (GlaxoSmithKline) and Gardasil (Merck), by assessing immunogenicity and safety through one month after completion of the three-dose vaccination course. Women (n = 1106) were stratified by age (18-26, 27-35, 36-45 years) and randomized (1:1) to receive Cervarix (Months 0, 1, 6) or Gardasil (Months 0, 2, 6). At Month 7 after first vaccination, all women in the according-to-protocol cohort who were seronegative/DNA negative before vaccination for the HPV type analyzed had seroconverted for HPV-16 and HPV-18 serum neutralizing antibodies, as measured by pseudovirion-based neutralization assay (PBNA), except for two women aged 27-35 years in the Gardasil group who did not seroconvert for HPV-18 (98%). Geometric mean titers of serum neutralizing antibodies ranged from 2.3-4.8-fold higher for HPV-16 and 6.8-9.1-fold higher for HPV-18 after vaccination with Cervarix compared with Gardasil, across all age strata. In the total vaccinated cohort (all women who received at least one vaccine dose, regardless of their serological and DNA status prior to vaccination), Cervarix induced significantly higher serum neutralizing antibody titers in all age strata (p < 0.0001). Positivity rates for anti-HPV-16 and -18 neutralizing antibodies in cervicovaginal secretions and circulating HPV-16 and -18 specific memory B-cell frequencies were also higher after vaccination with Cervarix compared with Gardasil. Both vaccines were generally well tolerated. The incidence of unsolicited adverse events was comparable between vaccinated groups. The incidence of solicited symptoms was generally higher after Cervarix, injection site reactions being most common. However, compliance rates with the three-dose schedules were similarly high (>or= 84%) for both vaccines. Although the importance of differences in magnitude of immune response between these vaccines is unknown, they may represent determinants

The assessment of the gender and age-specific seroprevalence of human papillomavirus (HPV) is essential for planning of HPV vaccine implementation into the preventive programs. In this study, we aimed to determine the age-specific seroprevalence of HPV-16 and 18 in both males and females in Tehran, Iran. Three hundred and seventy-eight women (10-35 years) and 162 men (10-25 years) from Tehran, Iran, were enrolled. Anti-HPV IgG antibodies against HPV-16 and HPV-18 were detected by ELISA using papillomavirus type 16 and 18 L1-capsids as antigen. HPV-16 antibody was detected in 15.6 and 13.6% of women and men, respectively. Antibody against HPV-18 was found positive in 12.7 and 8% of women and men, respectively. The highest seroprevalence of HPV-16 and 18 were seen in women aged 26-30 years (22.2 and 19.4%, respectively), and the lowest HPV-16 and 18 seropositivity rates were seen in males and females aged 10-15 years (9.3 and 1.9%, respectively). In our cohort of study, in males, both anti-HPV-16 and 18 increased after age 15 years, peaking in men aged 21-25 years. In women, both HPV-16 and 18 seropositivity increased after 15 years, declined at 21-25 years, peaked in women aged 26-30 years and again decreased after 30 years. Our data showed increasing exposure rate to high-risk HPV vaccine types in our studied population over 15 years of age. In order to prevent the HPV-related cancers, implementation of HPV vaccine into the national immunization program in Iran and vaccination of females and males less than 15 years of age are suggested.

The epidemiology of type 1 diabetes mellitus may provide insights into the pathogenesis of the disease. The aim of this work was to characterize the trend of the incidence of type 1 diabetes mellitus in Romanian children aged from 0 to 17 years over a 10-year interval. Data regarding new cases were obtained from two sources: (1) The Romanian Childhood Diabetes Registry and (2) Records of the Medical Center "Cristian Serban", Buzias. The demographic data were retrieved from the National Institute for Statistics. The incidence was calculated for the age groups 0-4, 5-9, 10-14, and 15-17 years. A total of 3196 new cases, aged below 18 years, were found by both the sources. There were significant differences between the groups (p=0.012), the mean incidence being highest in the age group 10-14 years (9.6/100,000/year, 95% CI 9-10.1) and lowest in children aged from 0 to 4 years (4.8/100,000/year, 95% CI 4.4-5.3). Boys were slightly more frequently affected than girls (p=0.038). The age and gender adjusted incidence of type 1 diabetes mellitus increased significantly (p<0.001) from 6.2/100,000/year (95% CI 5.5-6.9) in 2002 to 9.3/100,000/year (95% CI 8.4-10.3) in 2011. The raise in incidence was noticed in all age groups except for 15-17 years. Romania is a country with an intermediate incidence of type 1 diabetes mellitus in children, which is slightly higher in boys than in girls. The incidence of type 1 diabetes mellitus increased continuously during the 10-year survey, with the exception of the oldest teens.

Dual energy x-ray absorptiometry (DEXA) offers the possibility of assessing regional soft tissue composition, i.e. lean mass (LM) and fat mass: LM may be considered a measure of muscle mass. We examined age-related differences in LM, percentage fat (%fat) and muscle strength in 100 healthy non-athletic women aged 18-87 years. Relationships between muscle strength and leg LM in 20 elite female weight lifters and in 18 inactive women with previous hip fractures were also studied. The LM and %fat of the whole body, trunk, arms and legs were derived from a whole body DEXA scan. Isokinetic knee extensor strength (KES) and flexor strength (KFS) at 30 degrees.s-1 were assessed using an isokinetic dynamometer. The women aged 71-87 years had 35% lower KES and KFS than the women aged 18-40 years (P < 0.0001). Differences in LM were less pronounced. The LM of the legs, for instance, was 15% lower in the old than in the young women (P < 0.0001). In a multiple regression analysis with age, body mass, height and leg LM or KES as independent variables and KES or leg LM as the dependent variable, age was the most important predictor of KES (r(partial) = -0.74, P < 0.0001). The same applied to KFS. Body mass, not age, was the most important predictor of leg LM (r(partial) = 0.65, P < 0.0001) and of LM at all other measurement sites. The LM measured at different regions decreased equally with increasing age. The KES:leg LM ratio was negatively correlated with age (r = -0.70, P < 0.0001). The weight lifters had significantly higher KES:leg LM ratios than age-matched controls (+ 12%, P < 0.0001) and vice versa for the women with previous hip fractures (-36%, P < 0.0001). In conclusion, from our study it would seem that in healthy nonathletic women, age is a more important determinant of muscle strength than is LM as measured by DEXA. Muscle strengthening exercises and inactivity seem to have a considerably stronger influence on muscle strength than on LM.

The discovery of reliable means to determine the age of an individual is a fundamental objective in forensic medicine, in consideration of the constant increase of illegal immigration into the European community. In 2008 Cameriere et al. developed a method based on the relationship between age and the third molar index (I3m), which assesses the degree of maturation of the third molar through measurements made on orthopantomography. The purpose of this work was to test the accuracy of Cameriere's cut-off for I3m as a tool to assess full age (18) on a new sample of living subjects. Orthopantomographs of 287 Italian living subjects aged between 13 and 22 years have been randomly selected and included in the study. Identification number, gender, date of birth and date of execution of the radiograph were recorded for each patient on a Microsoft Excel® spreadsheet. Radiographs were digitalized and analyzed using a computerized image-processing program (Adobe® Photoshop® CS4). The results show that the sensitivity of the test was 84.1% and the specificity was 92.5%. The estimated post-test probability was 90.1%, with a confidence interval of 95% (83.6%, 95.2%). Thus, the probability that a person being positive to the test has 18 or more years of age was 90.1%. The results highlight the contribution of Cameriere's cut-off value for the I3m in the assessment of full age, always remembering that the simultaneous employment of previously introduced complementary methods is essential for the purpose.

In routine practice, intensive care physicians rarely have to manage children under 18years of age, particularly those under 15. This study's objectives were to assess the quality of training in pediatrics of adult intensive care teams, to document the workload generated by care of pediatric patients, and to identify the difficulties encountered in managing minors as patients. A survey was administered in Lower Normandy from 4 April 2012 to 1 September 2012. Physicians, residents, nurses, and nurses' aides practicing in one of the nine intensive care units of Lower Normandy were asked to complete an electronic or paper format questionnaire. This questionnaire assessed their level of pediatric training, the workload management of pediatric patients entailed, and the challenges posed by these patients. One hundred and nine questionnaires were returned (by 26 attending physicians, 18 residents, 38 nurses, and 27 nurses' aides). Eighty-three of the respondents (76%) had no experience in a pediatric unit of any kind. Forty-two percent thought that the pediatric age range lies between 3months and 15years of age. However, more than 50% of respondents would like the upper limit to be 16years or even older. Ninety-three respondents (85%) estimated having some exposure to pediatric patients in their routine practice, but this activity remained quite low. Seventy-three (67%) reported difficulties with the management of these young patients. This survey provides current information regarding the level of training of adult intensive care unit professionals and their concerns about managing patients under 18years of age, both in terms of workload and specific challenges.

The genetic and environmental etiology of individual differences was examined in initial level and change in psychopathic personality from ages 9 to 18 years. A piecewise growth curve model, in which the first change score (G1) influenced all ages (9-10, 11-13, 14-15, and 16-18 years) and the second change score (G2) only influenced ages 14-15 and 16-18 years, fit the data better did than the standard single slope model, suggesting a turning point from childhood to adolescence. The results indicated that variations in levels and both change scores were mainly due to genetic (A) and nonshared environmental (E) influences (i.e., AE structure for G0, G1, and G2). No sex differences were found except on the mean values of level and change scores. Based on caregiver ratings, about 81% of variance in G0, 89% of variance in G1, and 94% of variance in G2 were explained by genetic factors, whereas for youth self-reports, these three proportions were 94%, 71%, and 66%, respectively. The larger contribution of genetic variance and covariance in caregiver ratings than in youth self-reports may suggest that caregivers considered the changes in their children to be more similar as compared to how the children viewed themselves.

The prevalence of overweight and obesity has increased considerably in Saudi Arabia in the past two decades. We conducted this study because to examine trends in weight gain with age and related anthropometric measurements in Saudi Arabia such data are limited. To determine trends in overweight and obesity and examine anthropometric indices by age group. Analytical cross-sectional study. Universities, malls, and hospitals in the cities of Mecca, Jeddah, and Al-Taif. Participants were selected by convenience sampling. Body weight, body fat percentage, visceral fat percentage, and skeletal muscle percentage were measured with the Omron body composition monitor device. Waist circumference, height, and body mass index (BMI) were also measured. Changes in BMI, body fat percentage, visceral fat percentage, and skel-etal muscle with age for both genders. We selected 2548 Saudis, 1423 males and 1125 females, aged 18 to 60 years. A significant trend (ptrend < .001) for BMI and all anthropometric indices was observed with age for both genders. About 55.1% of the participants were overweight and obese (BMI > 25 kg/m2). Obesity and overweight were more prevalent in men than in women and was observed early in both genders, at the ages of 18-19 in men and 30-39 years for women. In the age range of 40-60 years, muscle mass dropped significantly (P < .05) for both genders. Mean waist circumference and visceral fat were significantly (P < .001) higher in men than in women, but the mean total body fat percentage was higher in females than in males (P < .001). Significant trends were observed for BMI, WC, body fat, visceral fat, and muscle mass for both genders with age. National programs should be maintained to encourage physical activity and weight reduction as well as focusing on obesity-related lifestyle and behaviors at early ages to prevent weight gain and possibly muscle wasting with age. There was an unequal distribution in numbers of subjects between study groups

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.

Background Immune specific genes as well as genes regulating the formation of skin barrier are major determinants for eczema manifestation. There is a debate as to whether allergic sensitization and filaggrin gene (FLG) variants lead to eczema or FLG variants and eczema increase the risk of allergic sensitization. To investigate the time-order between eczema and allergic sensitization with respect to FLG variants, data from a large prospective study covering infancy to late adolescence were analyzed. Methodology/Principal Findings Repeated measurements of eczema and allergic sensitization (documented by skin prick tests) at ages 1, 2, 4, 10, and 18 years were ascertained in the Isle of Wight birth cohort (n = 1,456). Three transition periods were analyzed: age 1-or-2 to 4, 4 to 10, and 10 to 18 years. FLG variants were genotyped in 1,150 participants. Over the three transition periods, in temporal sequence analyses of initially eczema-free participants, the combined effect of FLG variants and allergic sensitization showed a 2.92-fold (95% CI: 1.47–5.77) increased risk ratio (RR) of eczema in subsequent examinations. This overall risk was more pronounced at a younger age (transition period 1-or-2 to 4, RR = 6.47, 95% CI: 1.96–21.33). In contrast, FLG variants in combination with eczema showed a weaker, but significant, risk ratio for subsequent allergic sensitization only up to 10 years of age. Conclusions/Significance Taking the time order into account, this prospective study demonstrates for the first time, that a combination of FLG variants and allergic sensitization increased the risk of eczema in subsequent years. Also FLG variants interacted with eczema and increased the risk of subsequent allergic sensitization, which, was limited to the younger age. Hence, early restoration of defective skin barrier could prevent allergic sensitization and subsequently reduce the risk of eczema development. PMID:22403702

A quadrivalent human papillomavirus vaccination program targeting females aged 12-13 years commenced in Australia in 2007, with catch-up vaccination of 14-26 year olds through 2009. We evaluated the program's impact on HPV prevalence among women aged 18-35 in 2015. HPV prevalence among women aged 18-24 and 25-35 was compared with prevalence in these age groups in 2005-2007. For women aged 18-24, we also compared prevalence with that in a postvaccine study conducted in 2010-2012. For the 2015 sample, Vaccination Register-confirmed 3-dose coverage was 53.3% (65.0% and 40.3% aged 18-24 and 25-35, respectively). Prevalence of vaccine HPV types decreased from 22.7% (2005-2007) and 7.3% (2010-2012), to 1.5% (2015) (P trend < .001) among women aged 18-24, and from 11.8% (2005-2007) to 1.1% (2015) (P = .001) among those aged 25-35. This study, reporting the longest surveillance follow-up to date, shows prevalence of vaccine-targeted HPV types has continued to decline among young women. A substantial fall also occurred in women aged 25-35, despite lower coverage. Strong herd protection and effectiveness of less than 3 vaccine doses likely contributed to these reductions.

The purpose of this study was to estimate the vaccination coverage (VC) rate in persons aged from 9 months to 18 years and to describe it according to the predictive factors of good vaccination status. Descriptive and etiological study. The study involved 1332 persons aged below 18 years and members of 521 representative households in French Guiana. VC was estimated by the proportion of people with complete immunization for 13 vaccines (four mandatory, seven recommended, and two specific). This vaccination status was described in terms of sociodemographic characteristics. The relationship between vaccination status and predictive factors was analyzed in a hierarchical mixed, polytomic, and ordered regression model. For compulsory vaccination, VC was 81.2% for yellow fever, 63.4% for diphtheria, 61.7% for tetanus, and 61.6% for poliomyelitis. The proportion of people with complete immunization for recommended vaccines remains well below 50% (11.7% for pneumococcus and 6.2% for meningitis). Regardless of the vaccine, respondents aged 3-7 years were 2.5 times more likely to have an up-to-date vaccination compared to respondents younger than 3 years of age (P < 0.001). The VC observed in this study is still below the departmental objectives. The link between age and vaccination status could be explained by the efforts of the national education authorities to systematically check health cards for preschool and school enrollment.

Background The six-minute walk test (6MWT) is a safe, simple, inexpensive tool for evaluating the functional exercise capacity of patients with chronic respiratory disease. However, there is a lack of standard reference equations for the six-minute walk distance (6MWD) in the healthy Chinese population aged 18–59 years. Aims The purposes of the present study were as follows: 1) to measure the anthropometric data and walking distance of a sample of healthy Chinese Han people aged 18–59 years; 2) to construct reference equations for the 6MWD; 3) to compare the measured 6MWD with previously published equations. Method The anthropometric data, demographic information, lung function, and walking distance of Chinese adults aged 18–59 years were prospectively measured using a standardized protocol. We obtained verbal consent from all the subjects before the test, and the study design was approved by the ethics committee of Wenzhou People's Hospital. The 6MWT was performed twice, and the longer distance was used for further analysis. Results A total of 643 subjects (319 females and 324 males) completed the 6MWT, and average walking distance was 601.6±55.51 m. The walking distance was compared between females and males (578±49.85 m vs. 623±52.53 m; p < 0.0001) and between physically active subjects and sedentary subjects (609.3±56.17 m vs. 592±53.23 m; p < 0.0001). Pearson’s correlation indicated that the 6MWD was significantly correlated with various demographic and the 6MWT variables, such as age, height, weight, body mass index (BMI), heart rate after the test and the difference in the heart rate before and after the test. Stepwise multiple regression analysis showed that age and height were independent predictors associated with the 6MWD. The reference equations from white, Canadian and Chilean populations tended to overestimate the walking distance in our subjects, while Brazilian and Arabian equations tended to underestimate the walking distance.

Purpose Little is known about the risk factors for nonmedical use (NMU) of prescription stimulants among adolescent girls. We aimed to measure the association of nonmedical prescription stimulant use with empirically linked risk factors, including weight control behavior (WCB), gambling, and depressed mood, in pre-teen and teenaged girls. Methods We assessed the relationship between age and race, gambling, WCB, depressive mood, and nonmedical prescription stimulant use using multivariable logistic regression. The study sample included 5,585 females, aged 10–18 years, recruited via an entertainment venue intercept method in 10 U.S. metropolitan areas as part of the National Monitoring of Adolescent Prescription Stimulants Study (2008–2011). Results NMU of prescription stimulants was reported by 6.6% (n = 370) of the sample. In multivariable logistic regression, 1-year increase in age was associated with a 21% (95% confidence interval [CI]: .15, .28) increase in risk for NMU. Whites and other race/ethnicity girls had 2.67 (CI: 1.85, 3.87) and 1.71 (1.11, 2.65) times higher odds for NMU, compared to African-Americans. Depressive mood (adjusted odds ratio: 2.69, CI: 2.04, 5.57) and gambling (adjusted odds ratio: 1.90, 1.23, 2.92) were associated with increased odds for NMU. A dose-response was identified between WCB and NMU, where girls with unhealthy and extreme WCB were over five times more likely to endorse NMU. Conclusions We contribute to the literature linking WCB, depression, gambling, and the NMU of prescription stimulants in any population and uniquely do so among girls. PMID:27998704

To identify the trends of vegetables and fruits consumption among Chinese adults aged 18 to 44 years old from 1991 to 2011. Twenty four hour dietary recall data from China Health and Nutrition Survey (1991, 1993, 1997, 2000, 2004, 2006, 2009 and 2011) were used to identify the trends of vegetables and fruits consumption among Chinese between 18 and 44 years old. From 1991 to 2011, the proportion of daily consumption of vegetables rarely varied, while the vegetables intake declined significantly; and the proportion of daily consumption and intake of fruits kept increasing as follows. By 2011, the proportion of daily consumption and intake of vegetables and fruits among the respondents were 99.7%, 48.0%, 321.6 g/d, and 90.1 g/d respectively. A significant drop was found in the vegetables intake among the respondents against the vegetables intake as recommended by the Chinese dietary guidelines, up to 50.2% in 2011; a significant rise was found in the fruits intake of the respondents against the fruits intake as recommended by the said guidelines, up to 17.4% in 2011. The average daily intake of vegetables and fruits of young and middle-aged residents (18-44 age group) in nine provinces in China was found lower than that recommended in the Chinese dietary guidelines; in view of the high proportion of people having less vegetables and fruits intake that those recommended by the Chinese dietary guidelines, further measures are expected to encourage their vegetables and fruits intake.

The larger contribution of genetic variance and covariance in caregiver ratings than in youth self-reports may suggest that caregivers considered the changes in their children to be more similar as compared to how the children viewed themselves.

Objective: To investigate the characteristics of geographic distribution and change trend of myopia prevalence for children and adolescents aged 7-18 years old from 2005 to 2014, which provides the basis for the prevention of myopia. Methods: Research material was selected from the data of 2005, 2010, and 2014 Chinese National Survey on Students Constitution and Health, including 31 provinces (with the exception of Hong Kong, Macao, and Taiwan). The complete detection data of binoculus in children and adolescents aged 7-18 years old were selected as our research objects. The research objects of three studies were 233 505, 216 474, and 215 160, respectively. We analyzed the characteristics of geographic distribution and change trend of myopia prevalence for children and adolescents aged 7-18 years old in 31 provinces from 2005 to 2014. Results: The overall myopia detection rates in Chinese children and adolescents aged 7 to 18 years old in 31 provinces were 47.4% (111 707/235 505), 55.6% (120 456/216 474), and 57.2% (122 965/215 160) in 2005, 2010 and 2014, respectively. The growth range in this two phases were 8.0 percentage points, and 1.6 percentage points, respectively, and the difference was statistically significant ( P< 0.05). The detection rate of Myopia was growing quickly from 2005 to 2010 and only three provinces were in the situation of decline state including Tianjin, Hainan, and Ningxia. 90.3 percent (28/31) of provinces were in the situation of growth state and the growth range was 1.3%-22.3%. The growth of myopia was in the situation of slowdown from 2010 to 2014, and 38.7 percent (12/31) of the provinces were in negative growth districts including Hebei, Shanxi, Inner Mongolia, Zhejiang, Fujian, Shandong, Hubei, Guangxi, Guizhou, Tibet, Qianghai, and Xinjiang. The growth range in other provinces was 0.4%-24.7%. Conclusion: The myopia detection rate was at a higher level and growing constantly in China. There was large difference for myopia of

The purpose of this study was to explore the applicability of periodontal ligament visibility (PLV) at the 18-year threshold. This mandibular maturity marker is graded into four separate age related stages, PLV-A, PLV-B, PLV-C, and PLV-D. These are discernible on a dental panoramic tomograph (DPT). The sample comprised a total of 2000 DPTs evenly divided into half yearly age bands from 16.00 to 25.99 years with 50 females and 50 males in each age band. It was found that PLV-A and PLV-B had minimum values below the 18-year threshold. PLV-C and PLV-D in females had minimum values of 18.08 and 18.58 years, respectively. In males, the minimum values for PLV-C was 18.10 years and PLV-D was 18.67 years. It was concluded that the presence of PLV-C or PLV-D indicates that a subject is over 18 years with a very high level of probability.

Previous analyses have found that insurance status is a strong predictor of survival among patients with colorectal cancer aged 18 to 64 years. We investigated whether differences in comorbidity level may account in part for the association between insurance status and survival. We used 2003 to 2005 data from the National Cancer Data Base, a national hospital-based cancer registry, to examine the relationship between baseline characteristics and overall survival at 1 year among 64,304 white and black patients with colorectal cancer. In race-specific analyses, we used Cox proportional hazards models to assess 1-year survival by insurance status, controlling first for age, stage, facility type, and neighborhood education level and income, and then further controlling for comorbidity level. RESULTS; Comorbidity level was lowest among those with private insurance, higher for those who were uninsured or insured by Medicaid, and highest for those insured by Medicare. Survival at 1 year was significantly poorer for patients without private insurance, even after adjusting for important covariates. In these multivariate models, risk of death at 1 year was approximately 50% to 90% higher for white and black patients without private insurance. Further adjustment for number of comorbidities had only a modest impact on the association between insurance status and survival. In multivariate analyses, patients with > or = three comorbid conditions had approximately 40% to 50% higher risk of death at 1 year. CONCLUSION Among white and black patients aged 18 to 64 years, differences in comorbidity level do not account for the association between insurance status and survival in patients with colorectal cancer.

Since 2010, the Advisory Committee on Immunization Practices (ACIP) has recommended that all persons aged ≥6months receive annual influenza vaccination. We analyzed data from the 2015 National Internet Flu Survey (NIFS), to assess knowledge and awareness of the influenza vaccination recommendation and early influenza vaccination coverage during the 2015-16 season among adults. Predictive marginals from a multivariable logistic regression model were used to identify factors independently associated with adults' knowledge and awareness of the vaccination recommendation and early vaccine uptake during the 2015-16 influenza season. Among the 3301 respondents aged ≥18years, 19.6% indicated knowing that influenza vaccination is recommended for all persons aged ≥6months. Of respondents, 62.3% indicated awareness that there was a recommendation for influenza vaccination, but did not indicate correct knowledge of the recommended age group. Overall, 39.9% of adults aged ≥18years reported having an influenza vaccination. Age 65years and older, being female, having a college or higher education, not being in work force, having annual household income ≥$75,000, reporting having received an influenza vaccination early in the 2015-16 season, having children aged ≤17years in the household, and having high-risk conditions were independently associated with a higher correct knowledge of the influenza vaccination recommendation. Approximately 1 in 5 had correct knowledge of the recommendation that all persons aged ≥6months should receive an influenza vaccination annually, with some socio-economic groups being even less aware. Clinic based education in combination with strategies known to increase uptake of recommended vaccines, such as patient reminder/recall systems and other healthcare system-based interventions are needed to improve vaccination, which could also improve awareness.

1. To examine the prevalence of selected risk factors for atherosclerosis: overweight, tobacco smoking, low physical activity, psychological distress and type A personality (characterized by tenseness, impatience, competitiveness, and aggressiveness) in adolescents and to assess the frequency the coexistence of risk factors (≥3) in relation to gender, age and school type. A cross-sectional study was carried out in a representative sample of youth aged 16 and 18 years (N=2983) in 8 voivodeships in Poland. The frequency of five atherosclerosis risk factors and their coexistence (≥3) was examined using self-reported questionnaires, in relation to gender, age and school type. Logistic regression analyses were used to assess the influence of the variables (gender, age and school type) on odds ratios of risk factor coexistence. Low physical activity was the most common risk factor, statistically more frequent in students from Basic Vocational Schools than in other school types (p<0.05). In Basic Vocational Schools there was also the highest percentage of cigarette smokers (p<0.001). Psychological distress and type A behaviour were observed most frequently in students from General Upper Secondary Schools. The highest risk factor accumulation (≥3) was observed among students from Basic Vocational Schools (40%), significantly more frequent in girls than boys (47.5% and 37.5% respectively). Multivariable analyses show that students from Basic Vocational Schools had twice the odds (OR=2.25, p<0.001) to have the coexistence of risk factors for atherosclerosis as compared with students from General Upper Secondary Schools, girls had almost twice as many occurrences (OR=1.83, p<0.001) as boys and 18-year-olds 1.5 more than 16-year-olds (OR=1.46, p<0.001). 1. A significant difference in the prevalence of risk factors for atherosclerosis in youth from different school types requires precise definition of priority health promotion activities depending on school type. 2

To evaluate whether aggressive nutrition can improve long-term neurodevelopmental outcomes and growth in extremely low birth weight (ELBW) infants born appropriate for gestational age (AGA). This single-center cohort study included 137 ELBW AGA infants born in two epochs. The first group received standard nutrition (SN; n=79) consisting of amino acids started at 0.5g/kg/day on Day 4 of life and increased to 1.0g/kg/day. The second aggressive nutrition (AN) group received amino acids started at 1.5-2.0g/kg/day within 24h of life and increased to 3.5g/kg/day. Parenteral and enteral feedings were combined in both groups. Neurodevelopmental outcomes by the Kyoto Scale of Psychological Development and growth were followed up to 18months of corrected age or 3years of age and compared by univariate and multivariate analyses. Baseline characteristics were similar between the two groups. At 3years of age, AN children had a significantly greater mean value of head circumference, but not length or weight, than SN children (49.1 vs 48.0cm, p=0.014). The cognitive-adaptive (C-A) score in the AN group was also significantly higher than that in the SN group (98.3 vs 91.9 at 18months, p=0.039 and 89.5 vs 83.1 at 3years, p=0.047). AN infants born ≥26weeks of gestation were less likely to develop borderline disability in C-A, language-social and overall developmental scores compared to gestational age-matched SN infants. Parenteral and enteral AN after birth improved the long-term cognitive neurodevelopment in ELBW AGA infants, especially in those born ≥26weeks of gestational age, however results need to be confirmed in a larger, multi-site randomized trial.

Age 18 years is considered as the age of majority by most countries. To ascertain the age of interest, both third molar development (TMD) and eruption (TME) staging scores are beneficial without needing multiple imaging modalities. This study aimed to assess the chronological course of TMD and TME in a Malay sub-adult population and evaluate predictions when specific stage(s) of TMD and TME have been attained that are pertinent to the age group of interest (<18 years or ≥18 years). A sample of 714 digital panoramic images for subjects stratified by age between 14.1 and 23.9 years was retrospectively collected. The techniques described by Gleiser and Hunt (modified by Kohler) and Olze were employed to stage TMD and TME, respectively. A binary logistic regression was performed to predict the 18-year threshold with staging score as predictors. Stages 4-6 (TMD) and A-B (TME) for males and stages 4 (TMD) and A (TME) for females were found to discriminate the <18-year group. For both genders, stages 9-10 (TMD) and D (TME) can be used as reference stages to estimate whether a subject is likely to be ≥18 years, with 94.74-100% and 85.88-96.38% correct predictions, respectively. Stages 4 (TMD) and A (TME) can also be used to identify juveniles (<18 years) with a high degree of correct predictions, 100%. The juvenility of an individual is easily anticipated by using the specific staging scores of both third molar variables (TMD and TME) without complex calculations. Copyright © 2015 Elsevier Ltd.

Abstract Background. We previously reported the noninferiority 1 month after the last dose of 2-dose human papillomavirus 16/18 AS04-adjuvanted (AS04-HPV-16/18) vaccine schedules at months 0 and 6 (2D_M0,6) and months 0 and 12 (2D_M0,12) in girls aged 9–14 years compared with a 3-dose schedule at months 0, 1, and 6 (3D_M0,1,6) in women aged 15–25 years. Here, we report the results at study end (month 36 [M36]). Methods. Girls were randomized 1:1 and received 2 vaccine doses either 6 months (2D_M0,6) or 12 months apart (2D_M0,12); women received 3 doses at months 0, 1, and 6 (3D_M0,1,6). Endpoints included noninferiority of HPV-16/18 antibodies for 2D_M0,6 versus 3D_M0,1,6; 2D_M0,12 versus 3D_M0,1,6; and 2D_M0,12 versus 2D_M0,6; and assessment of neutralizing antibodies, T cells, B cells, and safety. Results. At M36, the 2D_M0,6 and 2D_M0,12 schedules remained noninferior to the 3D_M0,1,6 schedule in terms of seroconversion rates and 3D/2D geometric mean titers for anti-HPV-16 and anti-HPV-18. All schedules elicited sustained immune responses up to M36. Conclusions. Both 2-dose schedules in young girls remained noninferior to the 3-dose schedule in women up to study conclusion at M36. The AS04-HPV-16/18 vaccine administered as a 2-dose schedule was immunogenic and well tolerated in young girls. PMID:28591778

To develop and evaluate a test activity from which bimanual performance in adolescents with unilateral cerebral palsy (CP) can be observed and scored with the Assisting Hand Assessment (AHA), and to evaluate the construct validity of the AHA test items for the extended age range 18 months to 18 years. A new test activity was developed and evaluated for its ability to elicit bimanual actions in adolescents with (n=20) and without (n=10) unilateral CP. The AHA scores of 126 adolescents (mean age 14y 3mo, SD 2y 6mo; 71 males, 55 females) and 157 children with unilateral CP (mean age 6y 1mo, SD 2y 10mo; 102 males, 55 females) were analysed using the Rasch measurement model. The test activity elicited bimanual actions in 100% of typically developing adolescents and in 96.8% and 57.9% of adolescents with unilateral CP (moderately and severely limited hand function respectively). The scale demonstrated good construct validity; thus the same scoring criteria can be used for the age range studied. The new Assisting Hand Assessment for adolescents (Ad-AHA) activity is valid for use with 13- to 18-year-olds to elicit bimanual performance in adolescents with unilateral CP. The same AHA scoring criteria can be used both for children and for adolescents within the age range 18 months to 18 years. © 2016 The Authors.

To analyze lipid changes and their relationship with 25-hydroxy vitamin D3 (25-OH-D) levels in patients under 18 years old with type 1 diabetes mellitus (T1DM). A cross-sectional, descriptive study. Patients under 18 years with T1DM were enrolled by consecutive, nonrandomized sampling. Data collected included sex, age, pubertal stage, time since T1DM onset, weight, height, body mass index (BMI), waist circumference, glycosylated hemoglobin (HbA1c), 25-OH-D, total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), and triglycerides (TG). Results were stratified by sex, age, and pubertal stage. Data were analyzed using SPSS(®). Ninety patients with a mean age of 11.7 ± 3.6 years (51.1% males) and mean HbA1c levels of 7.5 ± 1.3% were enrolled. Of these, 26.6% had 25-OH-D levels<20 ng/mL and 13.3% 25-OH-D levels ≤ 15 ng/mL. No differences were found in 25-OH-D between patients with overweight or obesity and the rest. HDL-C levels<40 ng/mL were found in 1.1%, 34.4% had LDL-C levels ≥ 100 mg/dL, and 2.2% had TG levels ≥ 150 mg/dL. Patients with 25-OH-D<20 ng/mL had higher TG levels than the rest (76.80 ± 45.62 vs 57.55 ± 26.08; P=.04) in the multivariate analysis controlled for BMI, waist circumference, and HbA1c. A correlation was found between 25-OH-D and TG levels (-0.230; P=.029). Patients in our population with vitamin D deficiency had higher TG levels. Long-term follow-up should be performed to understand the potential impact of such levels on diabetes-related complications. Copyright © 2015 SEEN. Published by Elsevier España, S.L.U.

Data on the epidemiology of chronic kidney disease (CKD), which is a serious health problem and refers to a condition related to irreversible kidney damage that further progress to end-stage renal disease in children, are insufficient and data that are available were based on hospital records. The aim of this nationwide, population-based field study was to determine the prevalence of CKD in children in Turkey and to evaluate the association between CKD and possible risk factors such as obesity and hypertension. The study was the paediatric stratum (3622 children aged 5-18 years) of the previously published population-based survey of Chronic REnal Disease In Turkey (CREDIT study). Medical data were collected through home visits and interviews between November 2007 and July 2008; height, weight and blood pressure were also measured. Serum creatinine, total cholesterol, uric acid and complete blood count were determined from 12-h fasting blood samples, and spot urine tests were performed for subjects who gave consent to laboratory evaluation. Following adjustment according to gender, residence, age groups and geographical regions, the prevalence of children with estimated glomerular filtration rate (eGFR) <75 mL/min/1.73 m(2) was 0.94 [95% confidence interval (CI): 0.63-1.35], and the prevalence of children with CKD Stages 3-5 [National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (K/DOQI)] was 2600 (95% CI 1100-5100) per million age related population. The mean eGFR was found to increase with age; the ratios of children with eGFR <90 and <75 mL/min/1.73 m(2) were higher in younger age groups. The frequencies of overweight and obese children were 9.3 and 8.9%, respectively, and the mean eGFR was lower in patients with higher body mass index. The prevalence of hypertension and hypercholesterolaemia was 6.1 and 5.8%, respectively; the mean eGFR was lower in children with hypercholesterolaemia. This is the first population-based CKD study performed in

Victims of bullying are at risk for psychotic experiences in early adolescence. It is unclear if this elevated risk extends into late adolescence. The aim of this study was to test whether bullying perpetration and victimization in elementary school predict psychotic experiences in late adolescence. The current study is based on the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective community-based study. A total of 4720 subjects with bullying perpetration and victimization were repeatedly assessed between the ages of 8 and 11 years by child and mother reports. Suspected or definite psychotic experiences were assessed with the Psychosis-Like Symptoms semi-structured interview at age 18 years. Controlling for child's gender, intelligence quotient at age 8 years, childhood behavioural and emotional problems, and also depression symptoms and psychotic experiences in early adolescence, victims [child report at 10 years: odds ratio (OR) 2.4, 95% confidence interval (CI) 1.6-3.4; mother report: OR 1.6, 95% CI 1.1-2.3], bully/victims (child report at 10 years: OR 3.1, 95% CI 1.7-5.8; mother: OR 2.9, 95% CI 1.7-5.0) and bullies (child report at 10 years: OR 4.9, 95% CI 1.3-17.7; mother: OR 1.2, 95% CI 0.46-3.1, n.s.) had a higher prevalence of psychotic experiences at age 18 years. Path analysis revealed that the association between peer victimization in childhood and psychotic experiences at age 18 years was only partially mediated by psychotic or depression symptoms in early adolescence. Involvement in bullying, whether as victim, bully/victim or bully, may increase the risk of developing psychotic experiences in adolescence. Health professionals should ask routinely during consultations with children about their bullying of and by peers.

Persons from the United States who travel to developing countries are at substantial risk for hepatitis B virus (HBV) infection. Hepatitis B vaccine has been recommended for adults at increased risk for infection, including travelers to high or intermediate hepatitis B endemic countries. To assess hepatitis B vaccination coverage among adults ≥18 years traveling to a country of high or intermediate endemicity from the United States. Data from the 2015 National Health Interview Survey (NHIS) were analyzed to determine hepatitis B vaccination coverage (≥1 dose) and series completion (≥3 doses) among persons aged ≥18 years who reported traveling to a country of high or intermediate hepatitis B endemicity. Multivariable logistic regression and predictive marginal analyses were conducted to identify factors independently associated with hepatitis B vaccination. In 2015, hepatitis B vaccination coverage (≥1 dose) among adults aged ≥18 years who reported traveling to high or intermediate hepatitis B endemic countries was 38.6%, significantly higher compared with 25.9% among non-travelers. Series completion (≥3 doses) was 31.7% and 21.2%, respectively (P < 0.05). On multivariable analysis among all respondents, travel status was significantly associated with hepatitis B vaccination coverage and series completion. Other characteristics independently associated with vaccination (≥1 dose, and ≥3 doses) among travelers included age, race/ethnicity, educational level, duration of US residence, number of physician contacts in the past year, status of ever being tested for HIV, and healthcare personnel status. Although travel to a country of high or intermediate hepatitis B endemicity was associated with higher likelihood of hepatitis B vaccination, hepatitis B vaccination coverage was low among adult travelers to these areas. Healthcare providers should ask their patients about travel plans and recommend and offer travel related vaccinations to their

Objectives : The aim of the study was to determine the prevalence of smoking among children and adolescents aged 7-18 years, and also to determine the relationship between this addiction and the Body Mass Index (BMI). Methods : Basic anthropometric measurements were performed, and information concerning cigarette smoking and basic SES was gathered using the questionnaire method. Results : More than 5% of boys admit to smoking at the age of 10-11 years, and as many as 22% 18-year-olds admit to doing so. With regard to girls, the situation is slightly better because it is only among 14-year-olds that the percentage of smokers exceeds 5%. Smoking may affect average BMIs. Smoking had a negative impact on the magnitude of physical development indices among children between 8 and 12 years old. Conclusions : The percentage of smokers increases with age. Boys smoke more often than girls. Tobacco smoking in middle childhood (8-12 years) is associated with lower BMIs.

Anthrax vaccine adsorbed (AVA, BioThrax(®)) is recommended for post-exposure prophylaxis administration for the US population in response to large-scale Bacillus anthracis spore exposure. However, no information exists on AVA use in children and ethical barriers exist to performing pre-event pediatric AVA studies. A Presidential Ethics Commission proposed a potential pathway for such studies utilizing an age de-escalation process comparing safety and immunogenicity data from 18 to 20 year-olds to older adults and if acceptable proceeding to evaluations in younger adolescents. We conducted exploratory summary re-analyses of existing databases from 18 to 20 year-olds (n=74) compared to adults aged 21 to 29 years (n=243) who participated in four previous US government funded AVA studies. Data extracted from studies included elicited local injection-site and systemic adverse events (AEs) following AVA doses given subcutaneously at 0, 2, and 4 weeks. Additionally, proportions of subjects with ≥4-fold antibody rises from baseline to post-second and post-third AVA doses (seroresponse) were obtained. Rates of any elicited local AEs were not significantly different between younger and older age groups for local events (79.2% vs. 83.8%, P=0.120) or systemic events (45.4% vs. 50.5%, P=0.188). Robust and similar proportions of seroresponses to vaccination were observed in both age groups. AVA was safe and immunogenic in 18 to 20 year-olds compared to 21 to 29 year-olds. These results provide initial information to anthrax and pediatric specialists if AVA studies in adolescents are required. Copyright © 2015 Elsevier Ltd. All rights reserved.

Little is known about risk of custody loss or out-of-home placement among children whose mothers experience postpartum mental disorders, and whether this risk differs from that of children whose mothers had earlier onset of their mental disorder. National Danish registers comprising 1 868 467 births (1982-2012) were used to determine how the timing of maternal illness onset influences out-of-home placement risk up to age 18 years among children exposed to a maternal mental disorder. Compared to children unexposed to maternal mental illness, risk was higher for children exposed to a maternal mental disorder whose mothers had a first contact for a mental disorder in the 0-12 months of predelivery (8.17/1000 person-years; aIRR 4.56, 95% CI 4.08-5.09), the first 3 months postpartum (4.60/1000 person-years; 3.55, 2.95-4.26) and 4-12 months postpartum (6.49/1000 person-years; 3.93, 3.50-4.41). Risk was even higher for children exposed to a maternal mental disorder when illness onset was more than 1-year predelivery (9.11/1000 person-years; 5.48, 5.32-5.66). Risk of out-home placement in children exposed to mothers with a new-onset postpartum mental disorder is almost as high as in children whose mothers have long-standing illness. A better understanding of the trajectories of these mothers and children is warranted. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

To assess the estimated glucose disposal rate (eGDR), insulin dose, and lipoprotein profile in children with type 1 diabetes mellitus (T1DM) and overweight or obesity as compared to children with T1DM and normal weight. A total of 115 patients (aged 5-16 years) with T1DM on intensive insulin therapy were recruited. The following parameters were measured: weight, height, body mass index, waist and hip circumference, insulin dose, eGDR, glycosylated hemoglobin, blood pressure, and lipoprotein profile. Results were stratified by sex and age. No significant differences were found in eGDR between children with normal weight, overweight, and obesity. However, obese children older than 11 years had lower eGDR values (9.3±1.3 vs 10.1±0.8 mg kg(-1)min(-1); p<0.01). Insulin dose was higher in overweight and obese children, especially in IU/m2/day (37.7 vs 36.1 vs. 29.4 respectively; p<0.01). Obese children had higher low-density lipoprotein cholesterol levels than children with overweight and normal weight (106.5 vs 91.7 vs 91.5mg/dL respectively; p<0.01). No correlation was found between waist circumference and the different markers of insulin resistance. Values of eGDR values were lower in obese children with T1DM older than 11 years, and this may therefore be considered a marker of insulin resistance. Insulin dose was higher in diabetic patients with overweight or obesity, specially in IU/m2/day. Obese children with T1DM had a lipoprotein profile of cardiovascular risk. Copyright © 2012 SEEN.

Age-Dependent Human Hepatic Carboxylesterase 1 (Ces1) ...

EPA Pesticide Factsheets

Human hepatic carboxylesterase 1 and 2 (CES1 and CES2) are important for ester- and amide- bond containing pharmaceutical and environmental chemical disposition. Despite concern regarding juvenile sensitivity to such compounds, CES1 and CES2 ontogeny has not been well characterized. To define human hepatic microsomal and cytosolic CES1 and CES2 expression during early postnatal life, microsomal and cytosolic fractions were prepared using liver samples from subjects without liver disease [N=165, 1d-18 yrs]. Proteins were fractionated, detected and quantitated by western blotting. Median microsomal CES1 was lower among samples from subjects < 3 weeks of age (N=36) compared to the rest of the population (N=126; 6.27 vs 17.5 pmoles/mg microsomal protein, respectively; p<0.001; Kruskal Wallis test). Cytosolic CES1 increased sequentially with expression being lowest among samples from individuals between birth and 3 weeks of age (N=36), markedly greater among those from ages 3 weeks to 6 years (N=90), and then modestly greater still among those over 6 years of age (N=36; median values = 4.7, 15.8, and 16.6 pmoles/mg cytosolic protein, respectively; p values <0.001 and 0.05, respectively, Kruskal Wallis test). Microsomal CES2 also increased sequentially across the same three age groups with median values of 1.8, 2.9, and 4.2 pmoles/mg microsomal protein, respectively (p<0.001, both), whereas for cytosolic CES2, only the youngest age group differed from the two older g

A total of 1654 subjects (854 boys and 800 girls) who were part of the Ellisras Longitudinal Study completed the questionnaire. A significant (p < 0.05) number of boys (11.7%) compared to girls (8.8%) received free cigarettes from the members of the community. Bill boards were successful in advertising tobacco products among the Ellisras rural boys (17% boys and 12.8% for girls, p < 0.022). Multivariate analyses found significant association between cigarette smoking (OR = 1.7 95%CI 1.1-2.7 and Model 2 OR 1.6 95%CI 1.0-2.6 adjusted for age and gender) and advertisements of tobacco products on the TV screens, videos or movies. Exposure to tobacco products advertisements was high among Ellisras rural children. Though tobacco products legislation exists in South Africa, efforts should be taken by the health professionals to emphasize the danger of using tobacco products even among the illiterate. Teachers and parents should refrain from advertising tobacco products at schools and at homes.

Estimate the prevalence of dental caries based on clinical examinations and self-reports and compare differences in the prevalence and effect measures between the two methods among 18-year-olds belonging to a 1993 birth cohort in the city of Pelotas, Brazil. Data on self-reported caries, socio-demographic aspects and oral health behaviour were collected using a questionnaire administered to adolescents aged 18 years (n = 4041). Clinical caries was evaluated (n = 1014) by a dentist who had undergone training and calibration exercises. Prevalence rates of clinical and self-reported caries, sensitivity, specificity, positive and negative predictive values, absolute and relative bias, and inflation factors were calculated. Prevalence ratios of dental caries were estimated for each risk factor. The prevalence of clinical and self-reported caries (DMFT>1) was 66.5% (95%CI: 63.6%-69.3%) and 60.3% (95%CI: 58.8%-61.8%), respectively. Self-reports underestimated the prevalence of dental caries by 9.3% in comparison to clinical evaluations. The analysis of the validity of self-reports regarding the DMFT index indicated high sensitivity (81.8%; 95%CI: 78.7%-84.7%) and specificity (78.1%; 95%CI: 73.3%-82.4%) in relation to the gold standard (clinical evaluation). Both the clinical and self-reported evaluations were associated with gender, schooling and self-rated oral health. Clinical dental caries was associated with visits to the dentist in the previous year. Self-reported dental caries was associated with daily tooth brushing frequency. Based on the present findings, self-reported information on dental caries using the DMFT index requires further studies prior to its use in the analysis of risk factors, but is valid for population-based health surveys with the aim of planning and monitoring oral health actions directed at adolescents.

Abstract Background In Slovenia like in other countries, till recently, personal history of epithelial ovarian cancer (EOC) has not been included among indications for genetic counselling. Recent studies reported up to 17% rate of germinal BRCA1/2 mutation (gBRCA1/2m) within the age group under 50 years at diagnosis. The original aim of this study was to invite to the genetic counselling still living patients with EOC under 45 years, to offer gBRCA1/2m testing and to perform analysis of gBRCA1/2m rate and of clinico-pathologic characteristics. Later, we added also the data of previously genetically tested patients with EOC aged 45 to 49 years. Patients and methods All clinical data have to be interpreted in the light of many changes happened in the field of EOC just in the last few years: new hystology stage classification (FIGO), new hystology types and differentiation grades classification, new therapeutic possibilities (PARP inhibitors available, also in Slovenia) and new guidelines for genetic counselling of EOC patients (National Comprehensive Cancer Network, NCCN), together with next-generation sequencing possibilities. Results Compliance rate at the invitation was 43.1%. In the group of 27 invited or previously tested patients with EOC diagnosed before the age of 45 years, five gBRCA1/2 mutations were found. The gBRCA1/2m detection rate within the group was 18.5%. There were 4 gBRCA1 and 1 gBRCA2 mutations detected. In the extended group of 42 tested patients with EOC diagnosed before the age of 50 years, 14 gBRCA1/2 mutations were found. The gBRCA1/2m detection rate within this extended, partially selected group was 33.3%. There were 11 gBRCA1 and 3 gBRCA2 mutations detected. Conclusions The rate of gBRCA1/2 mutation in tested unselected EOC patients under the age of 50 years was higher than 10%, namely 18.5%. Considering also a direct therapeuthic benefit of PARP inhibitors for BRCA positive patients, there is a double reason to offer genetic testing to

Purpose Assessing medical and non-medical use of stimulants and diversion is a challenge, especially among youth, with different methods for recruitment, and definitions of non-medical use and use. The field needs inexpensive, yet effective and reliable, methods of data collection to understand the prescription drug use problem. Most studies of youth are school or web-based, and conducted with teens. Recent Findings The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) recruited 11,048 youth 10 to 18 years of age from urban, rural and suburban areas in ten US cities using an entertainment venue intercept study. This review discusses the effectiveness of the method and results from four cross sections as well as the representativeness of the sample. Lifetime prevalence of any stimulant use was 14.8%, with rates highest among rural 16 to 18 year olds. The rate of past 30 day use was 7.3%, with over half (3.9%) non-medical use. Nearly 12% of all youth (whether a user or not) reported lifetime incoming/outgoing diversion of prescription stimulants. Summary Because no study has focused on stimulant use among youth as young as 10 and 11, this study is a landmark for future comparisons and offers a unique strategy for sampling and data collection.

This clinical trial examined the safety and immunogenicity of annual revaccination with Fluzone(®) Intradermal (Sanofi Pasteur, Swiftwater, PA) vaccine compared to a standard intramuscular (IM) split-virion trivalent influenza vaccine (Fluzone(®), Sanofi Pasteur). This phase II, active-controlled, multi-centre, open-label trial was conducted in 2009 and 2010, and enrolled 1250 adults 18-64 years of age who were randomly selected from participants in a phase III influenza vaccine trial the previous year (NCT00772109). Subjects who had previously received the ID vaccine were randomized 2:1 to be revaccinated with the ID or IM vaccine and those who previously received the IM vaccine were randomized 1:1. Solicited reactions were recorded on the day of vaccination and continuing for the next 7 days, non-serious adverse events for 28 days, and serious adverse events for 6 months after vaccination. Hemagglutination inhibition antibody titres were assessed pre-vaccination and at day 28. Reactions were well-tolerated and resolved in the first 7 days, but erythema, induration, swelling, pruritus and ecchymosis were reported by more subjects receiving the ID vaccine than the IM vaccine. Compared to receipt of IM vaccine in the previous year, ID vaccine in the previous year led to statistically higher rates of erythema, swelling and induration after IM vaccine in the second year. Injection-site pain and systemic reactions did not differ between ID and IM vaccines. No treatment-related serious adverse events were reported. Geometric mean antibody titres, seroprotection rates, and seroconversion rates were non-inferior for the ID and IM vaccines for all three viral strains. The ID vaccine was as immunogenic as the IM vaccine, and raised no safety concerns. It can be used interchangeably with the IM vaccine for annual revaccination in adults 18-64 years of age in consecutive years without safety concerns. Copyright © 2013 Elsevier Ltd.

Peak oxygen uptake (VO2peak) is routinely scaled as mL O2 per kilogram body mass despite theoretical and statistical limitations of using ratios. To examine the contribution of maturity status and body size descriptors to age-associated inter-individual variability in VO2peak and to present static allometric models to normalize VO2peak in male youth soccer players. Total body and estimates of total and regional lean mass were measured with dual energy X-ray absorptiometry in a cross-sectional sample of Portuguese male soccer players. The sample was divided into three age groups for analysis: 8-12 years, 13-15 years and 16-18 years. VO2peak was estimated using an incremental maximal exercise test on a motorized treadmill. Static allometric models were used to normalize VO2peak. The independent variables with the best statistical fit explained 72% in the younger group (lean body mass: k = 1.07), 52% in mid-adolescent players (lean body mass: k = 0.93) and 31% in the older group (body mass: k = 0.51) of variance in VO2peak. The inclusion of the exponential term pubertal status marginally increased the explained variance in VO2peak (adjusted R(2 )= 36-75%) and provided statistical adjustments to the size descriptors coefficients. The allometric coefficients and exponents evidenced the varying inter-relationship among size descriptors and maturity status with aerobic fitness from early to late-adolescence. Lean body mass, lean lower limbs mass and body mass combined with pubertal status explain most of the inter-individual variability in VO2peak among youth soccer players.

The gold standard for diagnosis of HIV-1 infection in infants under the age of 2 years is DNA or reverse transcriptase polymerase chain reaction. However, these tests are expensive and therefore not available in resource-limited countries. With the increasing availability of antiretroviral drugs for prevention of mother-to-child transmission of HIV and treatment of AIDS in resource-poor countries, there is an urgent need to develop cheaper, alternative, and cost-effective laboratory methods for early diagnosis of infant HIV-1 infection that will be useful in identifying infected infants who may benefit from early cotrimoxazole prophylaxis or commencement of antiretroviral therapy. We evaluated an alternative method, the enzyme-linked immunosorbent assay-based qualitative ultrasensitive p24 antigen assay for diagnosis of subtype C HIV-1 infection in infants under the age of 2 years using DNA polymerase chain reaction as the reference method. The assay showed a sensitivity of 96.7% (95% CI: 93.0-100) for detection of HIV-1 infection among infants 0-18 months of age with a specificity of 96.1% (95% CI: 91.7-100). These evaluated parameters were not statistically different between infants aged 0-6 and 7-18 months. The ultrasensitive p24 antigen assay is a useful diagnostic test for detection of HIV-1 infection among infants aged 0-18 months.

The last study to establish centiles of main anthropometric measurements in Kinshasa was conducted over 60 years ago, which questions its current adequacy to describe or monitor growth in this population. To assess the nutritional status of school-aged children and adolescents and to estimate centile curves of height, weight and body mass index (BMI). A representative sample of 7541 school-aged children and adolescents (48% boys) aged 6-18 years was measured between 2010-2013. Smooth centiles of height, weight and BMI-for-age were estimated with the LMS method and compared with the WHO 2007 reference. Nutritional status was assessed by comparing measurements of height and BMI against the appropriate WHO cut-offs. Compared to the WHO reference, percentiles of height and BMI were generally lower. This difference was larger in boys than in girls and increased as they approached adolescence. The prevalence of short stature (< -2 SD) and thinness (< -2 SD) was higher in boys (9.8% and 12%) than in girls (3.4% and 6.1%), but the prevalence of overweight (> 1 SD) was higher in girls (8.6%) than in boys (4.5%). Children from Kinshasa fall below WHO centile references. This study established up-to-date centile curves for height, weight and BMI by age in children and adolescents. These reference curves describe the current status of these anthropometric markers and can be used as a basis for comparison in future studies.

According to the American Cancer Society, 25% of cancer survivors in the United States develop depression. The objective of this study is to assess factors associated with self-reported history of depression diagnosis among cancer survivors aged ≥18 years in the United States. Data were analyzed from the 2014 Behavioral Risk Factor Surveillance System (N = 6079). The Behavioral Risk Factor Surveillance System collects data about US residents regarding their health-related risk behaviors and events, chronic health conditions, and use of preventive services. Respondents were considered to have a history of depression diagnosis if they answered yes to the question "Has a doctor or other health care provider EVER told you that you have a depressive disorder, including depression, major depression, dysthymia, or minor depression?" Bivariate and multivariable logistic regression analyses were conducted to assess factors associated with depression in cancer survivors. Analyses were conducted using SAS 9.4. After adjusting for demographic and socioeconomic factors, females (AOR: 1.70; 95% CI, 1.50-1.97); those with an annual household income of $24 999 or less (AOR: 2.48; 95% CI, 1.95-3.16); $25 000 to $49 999 (AOR: 1.62; 95% CI, 1.31-2.02), and $50 000 to $74 999 (AOR: 1.35; 95% CI, 1.10-1.71); those who were not married (AOR = 1.37; 95% CI, 1.17-1.60); and those who perceived their health as poor (AOR = 2.33; 95% CI, 2.01-2.70), were significantly more likely to report a diagnosis of depression. The results indicate that gender, income, marital status, and perceived health status were associated with self-reported depression among cancer survivors aged ≥18 years in the United States.

Background: Infant-specific pertussis data, especially among neonates, are limited and variable. This study (NCT01890850) provides overall and age-specific pertussis incidence and associated health care utilization and costs among commercially insured infants in the US. Methods: Nearly 1.2 million infants born from 2005 to 2010 with commercial health plan coverage were followed during their first 12 months of life. Pertussis cases were identified from medical claims (International Classification of Diseases, 9th revision, Clinical Modification code: 033.0, 033.9, 484.3), and incidence rates were calculated. Each pertussis case was then matched to 10 comparators, so pertussis-related health care utilization and costs before and after the index date could be assessed. Results: The overall pertussis incidence rate among infants <12 months of age was 117.7/100,000 person-years; infants 3 months of age had the highest incidence rate (247.7/100,000 person-years). Infants diagnosed with pertussis were significantly more likely to have prior diagnoses of upper respiratory infection, cough and wheezing-related illnesses than comparators (P < 0.001). Pertussis cases were more likely to be hospitalized within 14 days after the index date (31.8% vs. 0.5%; P < 0.001) and their adjusted health care costs during follow-up were 2.82 times higher than comparators (P < 0.001; 95% confidence interval: 2.08–3.81). The incremental cost of pertussis during the 12-month follow-up period averaged $8271 (P < 0.001). The average incremental cost varied substantially by age, ranging from $18,781 (P < 0.001) to $3772 (P = 0.02) among infants 1 month and 7–12 months of age, respectively. Conclusions: The health burden of pertussis, particularly in the youngest infants, remains substantial, highlighting the need to intensify efforts to protect this most vulnerable population.

Preclinical animal model studies of brain energy metabolism and neuroinflammation in Alzheimer's disease have produced conflicting results, hampering both the elucidation of the underlying disease mechanism and the development of effective Alzheimer's disease therapies. Here, we aimed to quantify the relationship between brain energy metabolism and neuroinflammation in the APP/PS1-21 transgenic mouse model of Alzheimer's disease using longitudinal in vivo 18 F-FDG and 18 F-DPA-714) PET imaging and ex vivo brain autoradiography. APP/PS1-21 (TG, n = 9) and wild type control mice (WT, n = 9) were studied longitudinally every third month from age 6 to 15 months with 18 F-FDG and 18 F-DPA-714 with a one-week interval between the scans. Additional TG (n = 52) and WT (n = 29) mice were used for ex vivo studies. In vivo, the 18 F-FDG SUVs were lower and the 18 F-DPA-714 binding ratios relative to the cerebellum were higher in the TG mouse cortex and hippocampus than in WT mice at age 12 to 15 months ( p < 0.05). The ex vivo cerebellum binding ratios supported the results of the in vivo 18 F-DPA-714 studies but not the 18 F-FDG studies. This longitudinal PET study demonstrated decreased energy metabolism and increased inflammation in the brains of APP/PS1-21 mice compared to WT mice.

To investigate associations between disability and employment 1 year after traumatic brain injury (TBI) using the International Classification of Functioning, Disability and Health (ICF) as a conceptual model. A prospective study including 93 patients with moderate-to-severe TBI (aged 16-55 year). Disability components of the ICF model (impairments, activity limitations and participation restrictions) and personal factors (age, gender, pre-injury employment status) were used as independent variables. The outcome measure was employment at 1 year post-injury categorized into unemployed and employed groups. Personal factors, impairments (brain injury severity, overall trauma severity and number of impaired body functions) and activity limitations (motor and cognitive abilities) accounted for 57% of the variance in employment outcome. Multivariate analyses showed that the probabilities of being employed 1 year post-injury were 95% lower for patients who were unemployed pre-injury (OR = 0.05), 74% lower for those with more severe brain injury (OR = 0.26) and 82% lower for those with more cognitive limitations (OR = 0.18). Rehabilitation professionals should take into account the importance of the ICF model when planning vocational rehabilitation interventions for individuals with TBI and focus on targeting modifiable aspects related to employment outcome, such as the individual's cognitive ability.

The size and proportions of the human body change continuously in response to social change and economic development. As reported by papers on intergenerational changes in chest size, this part of the human body is also influenced by environmental factors. The aim of this study was to assess changes in the dimensions and proportions of the chest of children and adolescents over a span of 70 years. In 2010 an anthropological study was conducted on 3878 children and adolescents aged 3-18 years living in Kraków (Poland). Data on chest dimensions (breadth, depth, circumference, chest index) were compared to data from 1938 (3719 children) and 1983 (6464 children). In boys, chests became increasingly deep; in boys 18 years of age, the chest index increased by 4.8 units, unlike girls, whose chests markedly flattened. The chest index in girls 18 years of age decreased by 4.2 units. In almost all age categories these differences were statistically significant. Also, in all age categories, children studied in 2010 had a significantly bigger chest circumference than boys and girls surveyed in 1983, respectively, by averages of 3.6 cm and 3 cm. The main reason for these changes may be the socio-economic transformation, which has been especially strong in recent decades. These results may have practical importance in many areas of knowledge, including medicine, nutritional science, and sports. They can also be important for informing preventive measures that should be taken in order to increase the physical activity of children and youth, especially boys. © 2016 Wiley Periodicals, Inc.

To analyse the maternal identification of different stages of dental caries in children aged 1-3 years. A cross-sectional study was conducted with 274 children and their mothers. The mothers answered a questionnaire on the occurrence of dental caries in their children and completed questions addressing their demographic/socio-economic status. The oral examination of the children was performed using the International Caries Detection and Assessment System. Descriptive, Chi square test and Poisson regression statistical analyses were performed. The prevalence of initial and established/severe dental caries lesions by age were: 1 year (23.2 and 24.2%), 2 years (17.9 and 55.7%) and 3 years (23.3 and 60.3%) respectively. Significant associations between clinical examinations and the mothers' reports were observed among children aged 1 year old who had initial stage caries lesions (p = 0.006) and in children aged 1, 2 and 3 years old who had established/severe stage caries lesions (p < 0.001). After adjustment for confounding variables it was found that mothers were more able to identify dental caries both at initial (PR 4.01, 95% CI 1.35-11.94) and established/severe stages (PR 9.14, 95% CI 2.49-33.56) in children aged 1 year old. In children aged 2 and 3 years, this identification was more evident in the established/severe stage (2 years, PR 2.98, 95% CI 1.42-6.26; 3 years, PR 2.75, 95% CI 1.09-6.93). Mothers of children aged 1 year old identified dental caries at initial and established/severe stages. Mothers of children aged 2 and 3 years identified dental caries only at established/severe stages.

Participation in amateur street marathons has become increasingly popular and requires prior individual health risk assessment. The objective was to identify risk factors and readiness in registered runners. This was a cross-sectional study in a random sample (n = 510) of registered amateur runners 18-64 years of age, using a digital survey with IPAQ, Par-Q+, and STEPwise, with an expected physical inactivity rate of 35% (±5%). The study explored physical activity, (binge) alcohol consumption, fruit, vegetable, and salt intake, smoking, and readiness. Self-reported rates were: 97.4% recommended level of physical activity, 2.4% optimal fruit and vegetable intake, 3.7% smoking, and 44.1% binge drinking. 19.8% were Par-Q+ positive and 5.7% practiced supervised exercise. The analysis showed differences by age, sex, and socioeconomic status. Recreational runners followed the recommended levels of physical activity but did not score well on other risk factors. Prior evaluation of lifestyle-related risk factors and readiness provides a safer athletic strategy.

Lack of health insurance has been associated with poorer health status and with difficulties accessing preventive health services and obtaining medical care, especially for chronic diseases (1-3). Among workers, the prevalence of chronic conditions, risk behaviors, and having health insurance has been shown to vary by occupation (4,5). CDC used data from the 2013 and 2014 Behavioral Risk Factor Surveillance System (BRFSS) to estimate the prevalence of having no health care coverage (e.g., health insurance, prepaid plans such as health maintenance organizations, government plans such as Medicare, or Indian Health Service) by occupation. Among all workers aged 18-64 years, the prevalence of being uninsured declined significantly (21%) from 16.0% in 2013 to 12.7% in 2014. In both years there were large differences in the prevalence of being uninsured among occupational groups, ranging from 3.6% among the architecture and engineering occupations to 37.9% among the farming, fishing, and forestry occupations in 2013 and 2.7% among community and social services; and education, training, and library occupations to 37.0% among building and grounds cleaning and maintenance occupations in 2014 (p<0.001). In 2014, more than 25% of workers in four occupational groups reported having no health insurance (construction and extraction [29.1%]; farming, fishing, and forestry [34.6%]; food preparation and serving related [35.5%]; and building and grounds cleaning and maintenance [37.0%]). Identifying factors affecting differences in coverage by occupation might help to address health disparities among occupational groups.

Previously, we showed significant pairwise correlations among markedly impaired spatial learning and memory ability, decreased serum free triiodothyronine (FT3) and increased hippocampal SNAP-25 and Munc18-1 in old Kunming mice. However, whether these changes and the correlations occur in middle-age mice remains unclear. Since this age is one of the best stages to study age-related cognitive decline, we explored the spatial learning and memory ability, serum THs, cerebral SNAP-25 and Munc18-1 levels and their relationships of middle-aged mice in this study. The learning and memory abilities of 35 CD-1 mice (19 mice aged 6 months and 16 mice aged 12 months) were measured with a radial six-arm water maze (RAWM). The SNAP-25 and Munc18-1 levels were semi-quantified by Western blotting and the serum THs were detected by radioimmunoassay. The results showed the middle-aged mice had decreased serum FT3, increased dorsal hippocampal (DH) SNAP-25 and Munc18-1, and many or long number of errors and latency in both learning and memory phases of the RAWM. The Pearson's correlation test showed that the DH SANP-25 and Munc18-1 levels were positively correlated with the number of errors and latency in learning phases of the RAWM. Meanwhile, the DH SANP-25 and Munc18-1 levels negatively correlated with the serum FT3 level. These results suggested that reduced FT3 with increased DH SNAP-25 and Munc18-1 levels might be involved in the spatial learning ability decline in the middle-aged mice. © 2013 Elsevier B.V.

Significant changes in body composition are known to occur with aging. The aim of the present study was to provide a normative reference of body composition and to investigate age and sex-related differences in healthy subjects by multifrequency bioelectrical impedance analyzer (BIA).A cross-sectional study was conducted on a sample of 3451 healthy Chinese adults, 1611 males and 1840 females. The volunteers were enrolled in 5 different age bands (18-30, 31-40, 41-50, 51-60, 60+). All subjects were measured for weight and height and submitted to BIA, to determine body composition. Body composition measures accounted for differences between men and women.A decrease in fat-free mass and increase in percent body fat was observed with aging, although the phenomenon was proved to be attenuated in women. The central and visceral redistribution of fat mass was also shown along lifetime.This study is a report on body composition of healthy subjects, to be used as an important data for future investigations and differences between nationalities and countries.

MenACWY-CRM (Menveo®, Novartis Vaccines, Siena, Italy) is a quadrivalent meningococcal conjugate vaccine developed to help prevent invasive meningococcal disease caused by Neisseria meningitidis serogroups A, C, W, and Y. It is approved within the European Union in persons >2 years of age and in persons from 2 months to 55 years of age in the United States, among other countries. Little is known about the immunogenicity and safety of this vaccine in Taiwanese children >2 years and adolescents. This study assessed the immunogenicity and safety of a single injection of MenACWY-CRM vaccine in Taiwanese subjects aged 2-18 years old. In this phase III, multicentre, open-label study 341 subjects received one dose of MenACWY-CRM. Immunogenicity measures were rates of seroresponse (defined as the proportion of subjects with a postvaccination hSBA ≥1:8 if the prevaccination (baseline) titre was <1:4, or at least a fourfold higher hSBA titre than baseline if the prevaccination titre was ≥1:4), percentages of subjects with serum bactericidal activity (hSBA) ≥1:8 for serogroups A, C, W and Y and hSBA geometric mean titres (GMTs). Local and systemic reactions and all adverse events (AEs) were recorded for 7 days, and medically attended AEs for 1 month post-vaccination. Seroresponse rates after MenACWY-CRM vaccination at Day 29 for the serogroups A, C, W, and Y were 83%, 93%, 50%, and 65%, respectively. At Day 29 the percentages of subjects with hSBA ≥1:8 against all four serogroups A, C, W and Y were: 83%, 96%, 96% and 82%, respectively. GMTs against all serogroups rose by ≥7-fold from baseline to Day 29. The vaccine was well tolerated. A single dose of MenACWY-CRM demonstrated a robust immune response, and an acceptable safety profile in Taiwanese children and adolescents. Copyright © 2014 Elsevier Ltd. All rights reserved.

Background Many of the nongenetic causal risk factors of intellectual disability (ID) can be prevented if they are identified early. There is paucity on information regarding potential risk factors associated with this condition in Kenya. This study aimed to establish risk factors associated with severity of nongenetic intellectual disability (ID) among children presenting with this condition at Kenyatta National Hospital (KNH). Methods A hospital-based cross-sectional study was conducted over the period between March and June 2017 in pediatric and child/youth mental health departments of Kenyatta National Hospital (KNH), Kenya. It included children aged 2–18 years diagnosed with ID without underlying known genetic cause. Results Of 97 patients with nongenetic ID, 24% had mild ID, 40% moderate, 23% severe-profound, and 10% unspecified ID. The mean age of children was 5.6 (±3.6) years. Male children were predominant (62%). Three independent factors including “labor complications” [AOR = 9.45, 95% CI = 1.23–113.29, P = 0.036], “admission to neonatal intensive care unit” [AOR = 8.09, 95% CI = 2.11–31.07, P = 0.002], and “cerebral palsy” [AOR = 21.18, CI = 4.18–107.40, P ≤ 0.001] were significantly associated with increased risk of severe/profound nongenetic ID. Conclusion The present study findings suggest that perinatal complications as well as postnatal insults are associated with increased risk of developing severe-profound intellectual disability, implying that this occurrence may be reduced with appropriate antenatal, perinatal, and neonatal healthcare interventions.

On April 16, 1979, Massachusetts raised its legal drinking age from 18 to 20 years. Massachusetts was compared with New York State, exclusive of New York City and Nassau County. New York State retained an 18-year-old drinking age. Random telephone surveys with approximately 1,000 16-19 year olds in each state were undertaken prior to the law's enactment and twice at yearly intervals after the law to assess the law's impact on teenage drinking, driving after drinking, and non-fatal accident involvement. Fatal crash data reported to the US Department of Transportation by each state from April 16, 1976-April 15, 1981 were also analyzed. After the law, although the modes of procuring alcohol changed. No significant changes were observed in Massachusetts relative to New York in the proportion of surveyed teenagers who reported that they drank or in the volume of their consumption. The proportion of teenagers who drove after drinking heavily (six or more drinks at one time) did not decline in Massachusetts relative to New York. However, the frequency that teenagers reported driving after any drinking declined significantly in Massachusetts. Frequency of teenage driving after marijuana use and non-fatal teenage accidents declined at comparable rates in both states. The numbers of teenage nighttime single vehicle fatal accidents declined more in Massachusetts than New York, in the 18-19 year age group. Overall fatal accident trends among 16-19 year olds in the two states were similar.

Objective HbA1c is associated with cardiovascular risk in persons without diabetes and cardiovascular risk accumulates over the life course. Therefore, insight in factors determining HbA1c from childhood onwards is important. We investigated (lifestyle) determinants of HbA1c at age 12 years and the effects of growth on change in HbA1c and the tracking of HbA1c between the age of 8 and 12 years. Study Design and Methods Anthropometric measurements were taken and HbA1c levels were assessed in 955 children without diabetes aged around 12 years participating in the PIAMA birth cohort study. In 363 of these children HbA1c was also measured at age 8 years. Data on parents and children were collected prospectively by questionnaires. Results We found no significant association between known risk factors for diabetes and HbA1c at age 12 years. Mean(SD) change in HbA1c between ages 8 and 12 years was 0.6(0.7) mmol/mol per year (or 0.1(0.1) %/yr). Anthropometric measures at age 8 and their change between age 8 and 12 years were not associated with the change in HbA1c. 68.9% of the children remained in the same quintile or had an HbA1c one quintile higher or lower at age 8 years compared to age 12 years. Conclusion The lack of association between known risk factors for diabetes and HbA1c suggest that HbA1c in children without diabetes is relatively unaffected by factors associated with glycaemia. HbA1c at age 8 years is by far the most important predictor of HbA1c at age 12. Therefore, the ranking of HbA1c levels appear to be fairly stable over time. PMID:25875773

Objective: To compare the differences of CD(4) (+) T lymphocyte (CD(4)) counts between patients aged 18 and over, to explore the effect of age on treatment, 36 months after having received the China National Free AIDS Antiretroviral Treatment on HIV/AIDS. Methods: Through the National ART Information Ssystem, we selected those HIV/AIDS patients who initiated the ART 36 months after the ART, between January 1, 2010 and December 31, 2012 in Guangzhou, Liuzhou and Kunming. Patients were divided into age groups as 18-49, 50-59 and 60 or over year olds, at the baseline of treatment. Under different levels of baseline CD(4) counts, we chose the baseline and different time-point of CD(4) counts as dependent variables, applied mixed linear model to analyze the effects of age, viral suppression, gender, baseline CD(4)/CD(8) ratio and initial treatment regimen. Results: A total of 5 331 HIV/AIDS patients were recruited. No differences were found on age group ratios between different levels of baseline CD(4) counts. At the level of baseline CD(4)<200 cells/μl, both the 50-59 and 60 or above years old groups had lower CD(4) counts than the 18-49 year-old group, within 36 months after the initiation of ART. However, at the baseline CD(4) level of 200-350 cells/μl, no significant differences on CD(4) counts between the 50-59 year-old and 18-49 year-old groups were noticed. CD(4) counts seemed lower in the 60 and above year-old group than in the 18-49 year-old group. Conclusion: Age might serve as an influencing factor on CD(4) counts within 36 months after the initiation of ART, suggesting that earlier initiation of ART might be of help to the recovery of immune function in the 50-59 year-old group.

To examine the progression pattern of myopic maculopathy. Retrospective, observational case series. Highly myopic patients who had been followed up for 10 years or more. Using fundus photographs, myopic features were differentiated according to Meta-analysis of Pathologic Myopia (META-PM) Study Group recommendations. Progression pattern of maculopathy. The study included 810 eyes of 432 patients (mean age, 42.3±16.8 years; mean axial length, 28.8±1.9 mm; mean follow-up, 18.7±7.1 years). The progression rate of myopic maculopathy was 47.0 per 1000 eye-years. Within the pathologic myopia (PM) group (n = 521 eyes), progression of myopic maculopathy was associated with female gender (odds ratio [OR], 2.21; P = 0.001), older age (OR, 1.03; P = 0.002), longer axial length (OR, 1.20; P = 0.007), greater axial elongation (OR, 1.45; P = 0.005), and development of parapapillary atrophy (PPA; OR, 3.14; P < 0.001). Diffuse atrophy, found in 217 eyes without choroidal neovascularization (CNV) or lacquer cracks (LCs) at baseline, progressed in 111 (51%) eyes, leading to macular diffuse atrophy (n = 64; 64/111 or 58%), patchy atrophy (n = 59; 53%), myopic CNV (n = 18; 16%), LCs (n = 9; 5%), and patchy-related macular atrophy (n = 3; 3%). Patchy atrophy, detected in 63 eyes without CNV or LCs at baseline, showed progression in 60 eyes (95%), leading to enlargement of original patchy atrophy (n = 59; 59/60 or 98%), new patchy atrophy (n = 29; 48%), CNV-related macular atrophy (n = 13; 22%), and patchy-related macular atrophy (n = 5; 8%). Of 66 eyes with LCs, 43 eyes (65%) showed progression with development of new patchy atrophy (n = 38; 38/43 or 88%) and new LCs (n = 7; 16%). Reduction in best-corrected visual acuity (BCVA) was associated mainly (all P < 0.001) with the development of CNV or CNV-related macular atrophy and enlargement of macular atrophy. The most frequent progression patterns were an extension of peripapillary diffuse atrophy to macular diffuse

We evaluated the associations of teenage insulin and adolescent diet with 10-year weight gain in an analysis sample of black and white girls matched for pubertal stage, body mass index (BMI) (or fat mass), and insulin at ages 9 to 10 years. We hypothesized that preteen insulin and insulin resistance would interact with dietary factors to positively predict increases in BMI. Furthermore, we hypothesized that increased insulin and insulin resistance, interacting with higher caloric intake during adolescence, would lead to greater increments in BMI in black girls than in white girls. Prospective 10-year follow-up was performed on 215 pairs of black and white schoolgirls matched at baseline by BMI (or fat mass), insulin, and pubertal stage, with repeated measures of body habitus, insulin, and dietary intake. When matched for BMI, black girls had higher fat-free mass and white girls had higher fat mass at ages 9 to 10 years. Black-white differences in caloric intake were not significant at ages 9 to 10 years, but black girls consumed more calories at age 19 years. Black girls consumed a greater percentage of calories from fat throughout. At age 19 years, black girls had higher BMI, fat mass index, and insulin. When matched at ages 9 to 10 years for fat mass, black girls were heavier, had higher BMI, and had greater fat-free mass. By ages 18 to 19 years, black girls continued to have higher BMI, but had accrued higher fat mass and a higher percentage of body fat. By stepwise multiple regression, 10-year increases in BMI were predicted by ages 9 to 10 years BMI, 10-year change in insulin, and a 3-way interaction between ages 9 to 10 years insulin, adolescent caloric intake, and race (higher in black girls) (all Ps < .0001). Insulin at ages 9 to 10 years interacts with caloric intake to increase BMI by age 19 years. There appear to be intrinsic black-white metabolic differences that lead to greater gains in fat during adolescence in black girls. Evaluating BMI and insulin

Evaluating population-based data of hematologic malignancies (HMs) in older adults provides prognostic information for this growing demographic. Incidence rates and one- and five-year relative survival rates were examined for specific HMs among adults ages ≥75 years using data from the Surveillance, Epidemiology and End Results (SEER) Program. Hematologic malignancy cases (Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), multiple myeloma (MM), acute lymphocytic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML)) were reported to one of 18 SEER registries. Recent average annual (2010-2014) incidence rates and incidence trends from 1973 to 2014 were examined for cases ages ≥75 years. One- and five-year relative cancer survival rates were examined for adults ages ≥75 years diagnosed 2007-2013, with follow-up into 2014. From 1973 to 2014, incidence rates increased for NHL, MM, and AML, decreased for HL, and remained relatively stable for ALL, CLL, and CML among adults ages ≥75 years. The highest one- and five-year relative survival rates were observed among adults with CLL ages 75-84 years (1 year: 91.8% (95% CI = 91.8-90.8)) and 5 years: 76.5% (95% CI = 74.2-78.6)). The lowest one- and five-year survival rates were observed among adults with AML ages 75-84 (1 year: 18.2% (95% CI = 74.2-78.6) and 5 years: 2.7% (95% CI = 2.0-3.6)). Survival for older adults ages ≥75 years with HMs is poor, particularly for acute leukemia. Understanding the heterogeneity in HM outcomes among older patients may help clinicians better address the hematological cancer burden and mortality in the aging population. © 2018 The Authors.

Objectives. In 1999, New Zealand lowered the minimum purchasing age for alcohol from 20 to 18 years. We tested the hypothesis that this increased traffic crash injuries among 15- to 19-year-olds. Methods. Poisson regression was used to compute incidence rate ratios for the after to before incidence of alcohol-involved crashes and hospitalized injuries among 18- to 19-year-olds and 15- to 17-year-olds (20- to 24-year-olds were the reference). Results. Among young men, the ratio of the alcohol-involved crash rate after the law change to the period before was 12% larger (95% confidence interval [CI]=1.00, 1.25) for 18- to 19-year-olds and 14% larger (95% CI=1.01, 1.30) for 15- to 17-year-olds, relative to 20- to 24-year-olds. Among young women, the equivalent ratios were 51% larger (95% CI=1.17, 1.94) for 18- to 19-year-olds and 24% larger (95% CI=0.96, 1.59) for 15- to 17-year-olds. A similar pattern was observed for hospitalized injuries. Conclusions. Significantly more alcohol-involved crashes occurred among 15-to 19-year-olds than would have occurred had the purchase age not been reduced to 18 years. The effect size for 18- to 19-year-olds is remarkable given the legal exceptions to the pre-1999 law and its poor enforcement. PMID:16317197

In this observer-blind study (NCT00423046), women (N=1,106), stratified by age (18-26, 27-35, 36-45 y), were randomized (1:1) to receive the HPV-16/18 vaccine (Cervarix®, GlaxoSmithKline Biologicals, Months 0, 1, 6) or the HPV-6/11/16/18 vaccine (Gardasil® Merck & Co., Inc., Months 0, 2, 6). Month 7 results were previously reported; we now report Month 24 results. In the according-to-protocol cohort for immunogenicity (seronegative and DNA-negative at baseline for HPV type analyzed), seropositivity rates of neutralizing antibodies (nAbs) [pseudovirion-based neutralization assay] were, across all age strata, 100% (HPV-16/18 vaccine) and 97.5-100% (HPV-6/11/16/18 vaccine) for HPV-16, and 99.0-100% (HPV-16/18 vaccine) and 72.3-84.4% (HPV-6/11/16/18 vaccine) for HPV-18. Corresponding geometric mean titers (GMTs) were 2.4-5.8-fold higher for HPV-16 and 7.7-9.4-fold higher for HPV-18 with the HPV-16/18 vaccine versus the HPV-6/11/16/18 vaccine; HPV-16 and HPV-18 GMTs were significantly higher with the HPV-16/18 vaccine than the HPV-6/11/16/18 vaccine (p< 0.0001) in the total vaccinated cohort (received ≥1 vaccine dose, irrespective of baseline sero/DNA-status). Similar results were obtained using enzyme-linked immunosorbent assay (ELISA). Positivity rates and GMTs of antigen-specific IgG antibodies in cervicovaginal secretions (ELISA) were not significantly different between vaccines. At Month 24, CD4⁺ T-cell responses for HPV-16 and HPV-18 were higher with the HPV-16/18 vaccine; memory B-cell response was higher for HPV-18 with the HPV-16/18 vaccine and similar between vaccines for HPV-16. Both vaccines were generally well tolerated. Although an immunological correlate of protection has not been defined, differences in the magnitude of immune response between vaccines may represent determinants of duration of protection.

Anthropometric data indicate that the human phenotype is changing. Today's adult is greater in stature, body mass and fat mass. Accurate measurement of body composition is necessary to maintain surveillance of obesity within the population and to evaluate associated interventions. The aim of the present study was to construct and validate generalised equations for percentage body fat (%BF) prediction from anthropometry in 1136 adult men and women. Reference values for %BF were obtained using dual-energy X-ray absorptiometry. Skinfold thickness (SF) at ten sites and girth (G) at seven sites were measured on 736 men and women aged 18-81 years (%BF 5·1-56·8%). Quantile regression was employed to construct prediction equations from age and log-transformed SF and G measures. These equations were then cross-validated on a cohort of 400 subjects of similar age and fatness. The following generalised equations were found to most accurately predict %BF: Men: (age x 0·1) + (logtricepsSF x 7·6) + (logmidaxillaSF x 8·8) + (logsuprspinaleSF x 11·9) - 11·3 (standard error of the estimate: 2·5%, 95% limits of agreement: - 4·8, + 4·9) Women: (age x 0·1) + (logabdominalG x 39·4) + (logmidaxillaSF x 4·9) + (logbicepsSF x 11·0) + (logmedialcalfSF x 9·1) - 73·5 (standard error of the estimate: 3·0%, 95% limits of agreement: - 5·7, + 5·9) These generalised anthropometric equations accurately predict %BF and are suitable for the measurement of %BF in adult men and women of varying levels of fatness across the lifespan.

To describe the incidence and histologic patterns of eye cancers in Chinese in Taiwan. Beginning in 1979, cases of cancer in Taiwan were reported to the Taiwan National Cancer Registry. Information on all Chinese patients diagnosed with eye malignancies under the International Classification of Disease, Ninth Revision, site 190, was retrieved for analysis from the data bank of the Taiwan National Cancer Registry. In all, 733 cases with primary eye cancers were identified from 1979 to 1996, an 18-year period. The average annual age-standardized incidence of eye cancers was 2.46 per million population (2.57 for male and 2.33 for female). For cases less than 15 years of age, the most common eye malignancy was retinoblastoma (86.0%), followed by rhabdomyosarcoma (3.9%) and lymphoma (2.8%). For cases 15 years of age or older, the most common eye malignancy was melanoma (28.6%), followed by squamous cell sarcoma (21.0%) and lymphoma (20.8%). The time trends of the incidence of eye cancers were relatively stable over the 18-year period in Taiwan. Retinobalstoma, melanoma, and lymphoma were the three most common eye cancers in this Chinese population.

Depersonalization (DP) involves unpleasant experiences of detachment from one's sense of self or unreality in the environment. DP may occur in a broad range of conditions, among healthy persons due to sleep loss, drug induced, secondary to anxiety disorders or primary in depersonalization disorder. Although DP has an early age of onset, little is known about the prevalence and correlates of DP among adolescents. Between January and June 2011, we conducted a questionnaire-based representative survey of pupils aged 12-18 years in the federal state Rhineland-Palatinate of Germany. The final sample comprised 3,809 pupils. We analyzed the prevalence of depersonalization and its correlates regarding sociodemographic characteristics, substance abuse, global mental distress and resilience factors. One-third of the sample showed severe global mental distress, and 11.9 % were in the range of clinically significant depersonalization. Depersonalized students were less often living with both parents (67.3 vs. 75.7 %), came more often from an disadvantaged socioeconomic background, had a very severe level of global mental distress (comparable to psychiatric inpatients), were more often smoking and abusing cannabis and they suffered from specific impairments regarding social insecurity, global self-efficacy and active coping abilities. Experiences of depersonalization were very common among adolescents and may indicate an increased risk for poor academic achievement and mental health in the long term. Prospective studies are needed to investigate the course and clinical relevance of depersonalization for the development of the adolescents.

OBJECTIVE The authors examined the development of psychotic experiences and psychotic disorders in a large population-based sample of young adults and explored their relationship to psychotic phenomena earlier in childhood. METHOD The authors conducted a longitudinal birth cohort study of individuals assessed with the semistructured Psychosis-Like Symptom Interviews at ages 12 and 18 years. RESULTS Of the 4,724 individuals interviewed at age 18, 433 (9.2%) had either suspected (N=203 [4.3%]) or definite (N=230 [4.9%]) psychotic experiences. Of these, 79 (1.7%) met criteria for a psychotic disorder, and of those, only 50% sought professional help. All psychotic outcomes were more likely in young women and in those from socioeconomically disadvantaged backgrounds. Of the participants who had psychotic experiences at age 12, 78.7% had remitted by age 18. The risk of psychotic disorders at age 18 was greater in those with suspected (odds ratio=5.6, 95% CI=2.6-12.1) and especially in those with definite (odds ratio=12.7, 95% CI=6.2-26.1) psychotic experiences at age 12, and also among those with psychotic experiences at age 12 attributed to sleep or fever or with nonpsychotic experiences such as depersonalization. The positive predictive values for increasing frequency of experiences at age 12 predicting psychotic disorders at age 18 ranged from 5.5% to 22.8%. CONCLUSIONS Despite evidence for a continuum of psychotic experiences from as early as age 12, positive predictive values for predicting psychotic disorders were too low to offer real potential for targeted interventions. Psychotic disorders in young adults are relatively uncommon, but they constitute an important unmet need for care given that half of the individuals in this study who met criteria for a psychiatric disorder had not sought help for these problems despite high levels of associated distress and impairment.

The 'behaviour problems' are having major impact on child's bodily and social development. The family provides emotional support to an individual as well as plays a major role in the formation of one's personality. The quality and nature of the parental nurturance that the child receives will profoundly influence his future development. The knowledge of these family factors associated with behaviour problems may be helpful to identify at risk children. To study the family factors associated with behaviour problems amongst children of 6-18 Yrs age group. an adopted urban slum area of Govt. Medical College, Miraj Dist-Sangli. Cross sectional study. the sample size was calculated based upon 40% prevalence obtained in pilot study. Total 600 Children in the age group of 6-18 years residing in the urban slum area and their parents were interviewed with the help of predesigned, pretested proforma. chi-square test and risk estimate with Odd's ratio. Our study result reveals significant association between prevalence of behaviour problems with absence of either or both real parents and alcoholism in the parent or care taker. The behaviour problems have good prognosis if they are recognized earlier. Family has great role in prevention of behaviour problems in children, so parental counseling may be helpful.

Suicide among military personnel and young Veterans remains a health concern. This study examined stateside distribution of suicides by U.S. county to help focus prevention efforts. Using 2005-2012 National Violent Death Reporting System data from 16 states (963 counties, or county-equivalent entities), this study mapped the county-level distribution of suicides among current military and Veteran decedents aged 18-35 years. This study also compared incident circumstances of death between decedents in high-density counties (i.e., counties with the highest proportion of deaths) versus those in medium/low-density counties to better understand the precipitators of suicide in counties most affected. Last, this study identified potential military and Veteran Health Administration intervention sites. All analyses were conducted in 2015. Within the National Violent Death Reporting System participating states, an estimated 262 (33%) current military suicides occurred in just ten (1.0%) counties, and 391 (33%) Veteran suicides occurred in 33 (3.4%) counties. Mental health and intimate partner problems were common precipitating circumstances, and some circumstances differed between cases in high- versus those in medium/low-density counties. Multiple potential intervention sites were identified in high-density counties. These findings suggest that military and Veteran suicides are concentrated in a small number of counties. Increased efforts at these locales might be beneficial. Published by Elsevier Inc.

Objective: To examine the relation of performance on brief cognitive tests to development of clinically diagnosed Alzheimer disease (AD) dementia over the following 18 years in a sample of African Americans and European Americans. Methods: A composite cognitive test score based on tests of episodic memory, executive function, and global cognition was constructed in a prospective population-based sample of 2,125 participants (55% African American and 61% female) aged 65 years and older residing in 4 Chicago neighborhoods. Time before AD dementia diagnosis was categorized into 6 groups corresponding to data collection periods: 0.1–0.9, 1.0–3.9, 4.0–6.9, 7.0–9.9, 10.0–12.9, and 13.0–17.9 years. Results: Of 2,125 participants without clinical AD dementia, 442 (21%) developed clinical AD dementia over 18 years of follow-up. Lower composite cognitive test scores were associated with the development of AD dementia over the duration of the study. The magnitude of association between composite cognitive test score and development of AD dementia increased from an odds ratio of 3.39 (95% confidence interval 1.72, 6.67; p < 0.001) at 13.0–17.9 years to 9.84 (95% confidence interval 7.41, 13.06; p < 0.001) at 0.1–0.9 years, per SD increment. These associations were consistently larger among European Americans than among African Americans. Performance on individual cognitive tests of episodic memory, executive function, and global cognition also significantly predicted the development of AD dementia, with associations exhibiting a similar trend over 18 years. Conclusions: Our findings suggest that cognitive impairment may manifest in the preclinical phase of AD dementia substantially earlier than previously established. PMID:26109713

This study showed a retrospective analysis of the etiology, incidence and treatment of maxillofacial injuries in a pediatric and adolescent population of the State of Sao Paulo. We analyzed 2986 medical records of victims of facial trauma under 18 years, treated between 1999 and 2008 by the Department of Oral and Maxillofacial Surgery, Piracicaba Dental School, University of Campinas, Sao Paulo - Brazil. During this period, 757 patients under 18 were victims of maxillofacial trauma, of which, 112 patients had 139 lines of fracture in the mandible. The most affected age group were male adolescents. The bicycle accidents constituted the main etiology (34.82%). The conservative treatment was used in 51% of cases, and 49% received surgical treatment. Only 5 cases of postoperative complications were identified. The incidence of trauma and mandible fractures in pediatric and adolescent patients was high in the area of study. Bicycle accidents and falls being the main etiological factors. The group of adolescents was most affected. The conservative and surgical treatment was used almost in the same proportion.

The observer-blind, randomized, age-stratified, head-to-head study (NCT00423046) comparing immunogenicity and safety of HPV-16/18 and HPV-6/11/16/18 vaccines in healthy women aged 18-45 y was completed. Five y after vaccination, in subjects from the Month 60 according-to-protocol cohort (seronegative and DNA negative for HPV type analyzed at baseline), serum neutralizing antibody (nAb) responses induced by HPV-16/18 vaccine remained 7.8-fold (18-26-y stratum), 5.6-fold (27-35-y stratum) and 2.3-fold (36-45-y stratum) higher than those induced by HPV-6/11/16/18 vaccine for HPV-16. For HPV-18, the fold differences were 12.1, 13.0 and 7.8, respectively. At Month 60, all (100%) subjects in HPV-16/18 vaccine group and the majority (95.7%-97.5%) in HPV-6/11/16/18 vaccine group were seropositive for HPV-16. For HPV-18, the majority (98.1%-100%) of subjects in HPV-16/18 vaccine group were seropositive; however, seropositivity rates in HPV-6/11/16/18 vaccine group decreased considerably (61.1%-76.9%) across the 3 age strata. In the total vaccinated cohort (received ≥1 dose regardless of baseline HPV serostatus and DNA status), geometric mean titers for anti-HPV-16 and anti-HPV-18 nAb were higher in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. Based on the 5-y data, piece-wise and modified power-law models predicted a longer durability of nAb response for HPV-16/18 vaccine compared to HPV-6/11/16/18 vaccine. Beyond the differences apparent between the vaccines in terms of immunogenicity and modeled persistence of antibody responses, comparative studies including clinical endpoints would be needed to determine whether differences exist in duration of vaccine-induced protection.

Food insecurity is a preventable health threat and may precipitate central obesity and metabolic syndrome in children and adolescents in the United States. To examine (1) health by household food security status; and (2) differences and prevalence of central obesity among persons aged 12 to 18 years in the United States. The National Health and Nutrition Examination Survey was administered to a cross-sectional sample of persons aged 12 to 18 years in 1999 to 2006. Controlling for age, race/ethnicity, and sex differences in mean obesity and chronic disease factors across levels of food insecurity (analysis of covariance [Bonferroni post hoc] and ORs [logistic regression analyses]) were examined, as were differences in the rates of risk factors (χ(2) statistics). A total of 7435 participants were analyzed. Those from marginally food secure (n=751) and low-food secure (n=1206) (population size estimate, 26,714,182) households were significantly more likely than their high-food secure counterparts (n=4831) to be overweight (P=.036) (OR, 1.44), and those from marginally food secure households were 1.3-times more likely to be obese (P=.036). Nearly 25% of respondents from marginally food secure, low-food secure, and very low-food secure (n=647) households reported central obesity (P=.002), which was 1.4 to 1.5 times more likely than those from high-food secure households. Participants from high-food secure households had significantly higher mean high-density lipoprotein values (P=.019). Risk factors indicative of metabolic syndrome were present in 3.1%. Household food insecurity was associated with an increased likelihood of being overweight and having central obesity. Limitations included the use of cross-sectional data and some self-reported data and the inability to control for all moderating variables in obesity and overall health status.

There is accumulating literature on waning acellular pertussis vaccine-induced immunity, confirming the results of studies assessing the duration of protection of pertussis vaccines. To evaluate the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine's effect over time among those 11 to 18 years old, while accounting for the transition from whole-cell to acellular pertussis vaccines for the childhood primary series. Extended, retrospective analysis of reported pertussis cases between January 1, 1990, and December 31, 2014, in the United States. The analysis included all nationally reported pertussis cases. US Tdap vaccination program and the transition from whole-cell to acellular pertussis vaccines. Rate ratios of reported pertussis incidence (defined as incidence among 11- to 18-year-old individuals divided by the combined incidence in all other age groups) modeled with segmented regression analysis and age-specific trends in reported pertussis incidence over time. Between 1990 and 2014, 356 557 pertussis cases were reported in the United States. Of those, 191 914 (53.8%) were female and 240 665 (67.5%) were white. Overall incidence increased from 1.7 in 100 000 to 4.0 in 100 000 between 1990 and 2003, while latter years were dominated by epidemic peaks. Incidence was highest among infants younger than 1 year throughout the analysis period. Pertussis rates were comparable among all other age groups until the late 2000s, when an increased burden of pertussis emerged among children 1 to 10 years old, resulting in the second highest age-specific incidence. By 2014, 11- to 18-year-old individuals once again had the second highest incidence. While slope coefficients from segmented regression analysis showed a positive impact of Tdap immediately following introduction (slope, -0.4959; P < .001), a reversal in trends was observed in 2010 when rates of disease among 11- to 18-year-old individuals increased at a faster rate than

Introduction Young adults with hyperlipidemia, hypertension, and diabetes are at increased risk of developing heart disease later in life. Despite emphasis on early screening, little is known about awareness of these risk factors in young adulthood. Methods Data from the nationally representative cross-sectional survey National Health and Nutrition Examination Survey 2011–2014 were analyzed in 2017 to estimate the prevalence of self-reported awareness of hypercholesterolemia, hypertension, and diabetes in U.S. young adults aged 18–39 years (n=11,083). Prevalence estimates were weighted to population estimates using survey procedures, and predictors of awareness were identified using weighted logistic regression. Results Among U.S. young adults, the prevalence of hypercholesterolemia, hypertension, and diabetes was 8.8% (SE=0.4%), 7.3% (SE=0.3%), and 2.6% (SE=0.2%), respectively. The prevalence of borderline high cholesterol, blood pressure, and blood glucose were substantially higher (21.6% [SE= 0.6%], 26.9% [SE=0.7%], and 18.9% [SE=0.6%], respectively). Awareness was low for hypercholesterolemia (56.9% [SE=2.4%]) and moderate for hypertension and diabetes (62.7% [SE=2.4%] and 70.0% [SE=2.7%]); <25% of young adults with borderline levels of these risk factors were aware of their risk. Correlates of risk factor awareness included older age, insurance status, family income above the poverty line, U.S. origin, having a usual source of health care, and the presence of comorbid conditions. Conclusions Despite the high prevalence of cardiovascular risk factors in U.S. young adults, awareness remains less than ideal. Interventions that target access may increase awareness and facilitate achieving treatment goals in young adults. PMID:29433955

OBJECTIVE: The authors report on experience with liver transplantation for infants younger than 1 year of age. SUMMARY BACKGROUND DATA: Over the last 15 years, orthotopic liver transplant has become the only lifesaving procedure available for infants with end-stage liver disease. Many transplant centers initially required infants to reach a specific weight or age to minimize morbidity and mortality. Size-appropriate infant donors also were uncommon. As a result, many children, in the first few years of life, died of their disease. The availability of reduced-size cadaveric and living-related liver transplants has offered the ability to transplant the young infant with liver failure. METHODS: The authors instituted a program to aggressively transplant infants with liver failure in the first year of life using both cadaveric and living-related liver donors. RESULTS: Between June 1991 and January 1995, 13 infants were transplanted for rapidly progressive liver failure. Infant age ranged from 4 to 11 months (mean, 7.5 months). The cause of liver failure included biliary atresia (11), alpha 1-antitrypsin deficiency (1), and liver failure secondary to echovirus 7 (1). The United Network for Organ Sharing status at the time of transplant ranged from status 4, intensive care unit bound (4 patients); status 3, hospitalized (4 patients); or status 2, failing at home (5 patients). Six patients (46%) received cadaveric whole organ (2) or segmental transplants (4). Seven patients (54%) received left lateral segment living-related transplants from parental donors. After operation, patients received cyclosporine or FK506-based immunosuppression. Three patients (23%) required four retransplants (two cadaveric for primary nonfunction; one living-related for graft thrombosis in the face of fungal infection and bile leak). Postoperative complications included primary nonfunction (15%), rejection (85%), graft vascular thrombosis (15%, two of three revascularized successfully

This study aims to explore the prevalence of depression and anxiety in left-behind children, and to identify patterns of parents' migration and relative factors associated with depression and anxiety risk in this population. A cross-sectional survey using a school-based sample was conducted in Puyang, Hebei, North China in December 2012. 2283 students aged 10-18 years. Parental migration status, depression and anxiety disorder. 61.2% of participants were left-behind children. The prevalence rate of depression among left-behind children with both parents migrating (14.2%) was higher than that of children with one parent migrating (11.7%) and no parent migrating (12.6%). The prevalence rate of anxiety disorder for children with no parent migrating (25.1%) was higher than that for children living with one or neither parent (22.2% and 22.0%). The risk factors for depression were low-level social support (OR=3.46, 95% CI 2.00 to 6.01), average academic performance (OR=2.37, 95% CI 1.7 to 3.3) and low academic performance (OR=3.01, 95% CI 1.92 to 4.72), staying up late (OR=1.67, 95% CI 1.17 to 2.39), having difficulty falling asleep (OR=2.04, 95% CI 1.48 to 2.82) and being an only child (OR=1.73, 95% CI 1.04 to 2.89). The factors associated with anxiety disorder were being female (OR=2.09, 95% CI 1.64 to 2.66), being in high school (OR=1.8, 95% CI 1.38 to 2.36), physical abuse (OR=1.5, 95% CI 1.04 to 2.15), having difficulty falling asleep (OR=1.67, 95% CI 1.33 to 2.10) and low-level social support (OR=2.17, 95% CI 1.44 to 3.28) and middle-level social support (OR=1.82, 95% CI 1.3 to 2.56). Parents' migration was not associated with depression and anxiety in rural children aged 10-18 years, but academic performance at school, sleep problems and lack of social support were associated with depression and anxiety.

Jones, Jo

2008-08-01

This report presents national estimates of the prevalence of adoption for men and women 18-44 years of age, the demand for children to adopt by women, and women's preferences for characteristics of the adopted child. Analysis is based on data from the 2002 National Survey of Family Growth. This survey interviewed a nationally representative sample of women and men 15-44 years of age in their households. Results are weighted to produce national estimates of the characteristics of men and women who have adopted children, lifetime and current demand for adoption by women, and the characteristics of children preferred by women when they are considering adoption. Adoption remains rare in the United States. Among all women aged 18-44 in 2002, only 1.1% had adopted a child and 1.6% were currently seeking to adopt. Women were more likely to be currently seeking to adopt, to have ever sought to adopt, and to have actually adopted a child if they had used infertility services or had impaired fecundity. Older women and women who were in their second or later marriage were also more likely to have adopted a child. Hispanic and non-Hispanic black women were more likely to be currently seeking to adopt compared with non-Hispanic white women. More men than women have adopted children in their lifetimes. Among adopters, 17% of women and 6% of men were never married. Adopting a child has been and remains a relatively rare event in the United States. Adoption is a mechanism by which adults legalize their parental relationship to nonbiological children as well as a means to bring children into families. Studies examining adoption should include men as well as women and persons of all marital statuses.

The body mass index (BMI) is widely accepted as a measure of overweight and obesity in children. There are no BMI reference charts for Algerian children and adolescents. The purpose of this study was to construct BMI percentile curves appropriate for children aged 6-18 years in Algeria. The weight and height of 7772 (54.9% girls) healthy schoolchildren from Constantine (eastern Algeria) were measured in 2008/2009. Weight and height for age curves based on the same sample were published previously. The BMI for age percentile curves were estimated in girls and boys separately using the LMS smoothing method. In both sexes, the median BMI increased with age. Girls had lower BMI values than boys before the age of 10 years but they were higher after this age until 18 years of age. Within the study population, the prevalence of overweight (including obesity) and obesity in girls and boys together was 13.7% and 3.0%, respectively, according to the International Obesity Task Force (IOTF) and 16.9% and 4.9% according to the World Health Organization (WHO) (2007). The median BMI curves of Algerian girls and boys were generally lower than those observed in other Arab countries. Compared with other references, the median BMI values of girls were lower than those of a Belgian Flemish population and WHO 2007 until 14 years of age and higher than the French reference between 7 and 18 years of age. The BMI values of Algerian boys were close to the Belgian (Flemish population), French and WHO 2007 references between 6 and 9 years of age and generally lower thereafter. These BMI curves are complementary to the height and weight charts published previously for the assessment of growth in children and adolescents. They were developed according to international guidelines and could serve as a national reference. They could be used as a complement to the 0- to 5-year-old WHO 2006 standards.

Trends in sedentary lifestyle may have influenced adult body composition and metabolic health among individuals at presumably healthy weights. This study examines the nationally representative prevalence of prediabetes and abdominal obesity among healthy-weight adults in 1988 through 2012. We analyzed the National Health and Nutrition Examination Survey (NHANES) III (1988-1994) and NHANES for the years 1999 to 2012, focusing on adults aged 20 years and older who have a body mass index (BMI) of 18.5 to 24.99 and do not have diabetes, either diagnosed or undiagnosed. We defined prediabetes using glycated hemoglobin (HbA1c) level ranges from 5.7% to 6.4%, as specified by the American Diabetes Association. Abdominal obesity was measured by waist circumference and waist-to-height ratio. The prevalence of prediabetes among healthy-weight adults, aged 20 years and older and without diagnosed or undiagnosed diabetes, increased from 10.2% in 1988-1994 to 18.5% in 2012. Among individuals aged 45 years and older, the prevalence of prediabetes increased from 22.0% to 33.1%. The percentage of adults aged 20 years and older with an unhealthy waist circumference increased from 5.6% in 1988-1994 to 7.6% in 2012. The percentage of individuals with an unhealthy waist-to-height ratio increased from 27.2% in 1988-1994 to 33.7% in 2012. Adjusted models found that measures of abdominal obesity were not independent predictors of prediabetes among adults with a healthy BMI. Among individuals within a healthy BMI range, the prevalence of prediabetes and abdominal obesity has substantially increased. Abdominal obesity does not appear to be the primary cause of the increase. © 2016 Annals of Family Medicine, Inc.

This study aimed to systematically evaluate safety of probiotics and synbiotics in children ageing 0-18 years. This study is the third and final part in a safety trilogy and an update is provided using the most recent available clinical data (2008-2013) by means of the Common Terminology Clinical Adverse Events (CTCAE version 4.0) classification. Safety aspects are represented and related to number of participants per probiotic strain/culture, study duration, dosage, clinical condition and selected afflictions. Analysis of 74 clinical studies indicated that probiotic and/or synbiotic administration in children is safe with regard to the specific evaluated strains, dosages and duration. The population of children include healthy, immune compromised and obese subjects, as well as subjects with intestinal disorders, infections and inflammatory disorders. This study revealed no major safety concerns, as the adverse events (AEs) were unrelated, or not suspected to be related, to the probiotic or synbiotic product. In general the study products were well tolerated. Overall, AEs occurred more frequent in the control arm compared to children receiving probiotics and/or synbiotics. Furthermore, the results indicate inadequate reporting and classification of AEs in the majority of the studies. In addition, generalizability of conclusions are greatly limited by the inconsistent, imprecise and potentially incomplete reporting as well as the variation in probiotic strains, dosages, administration regimes, study populations and reported outcomes.

To succeed, pregnancies need to initiate immune biases towards T helper 2 (Th2) responses, yet little is known about what establishes this bias. Using the Illumina 450 K platform, we explored changes in DNA methylation (DNAm) of Th1, Th2, Th17, and regulatory T cell pathway genes before and during pregnancy. Female participants were recruited at birth (1989), and followed through age 18 years and their pregnancy (2011–2015). Peripheral blood DNAm was measured in 245 girls at 18 years; from among these girls, the DNAm of 54 women was repeatedly measured in the first (weeks 8–21, n = 39) and second (weeks 22–38, n = 35) halves of pregnancy, respectively. M-values (logit-transformed β-values of DNAm) were analyzed: First, with repeated measurement models, cytosine–phosphate–guanine sites (CpGs) of pathway genes in pregnancy and at age 18 (nonpregnant) were compared for changes (p ≤ 0.05). Second, we tested how many of the 348 pathway-related CpGs changed compared to 10 randomly selected subsets of all other CpGs and compared to 10 randomly selected subsets of other CD4+-related CpGs (348 in each subset). Contrasted to the nonpregnant state, 27.7% of Th1-related CpGs changed in the first and 36.1% in the second half of pregnancy. Among the Th2 pathway CpGs, proportions of changes were 35.1% (first) and 33.8% (second half). The methylation changes suggest involvement of both Th1 and Th2 pathway CpGs in the immune bias during pregnancy. Changes in regulatory T cell and Th17 pathways need further exploration.

The purpose of this study was to test the applicability of a standardised procedure for assessing Icelandic children's behaviour/emotional problems and competencies, and to identify differences related to demographic variables. This study focuses upon the method of using the Child Behavior Checklist (CBCL) by Achenbach to estimate the reported prevalence of parents and adolescents of emotional and behaviour problems in children from 2-16 years of age and self-reported prevalence of adolescents from 11-18 years, selected at random from the general population, both in urban and rural areas. The information was obtained by mailing checklists with a letter to parents of children 2-10 years of age. The checklists for adolescents 11-18 years of age were distributed by teachers in school. Those adolescents who were not in school received the checklists by mail at their homes. The Child Behavior Checklists used for analyses were completed by 109 parents of 2-3 year old children; 943 parents of 4-16 year old children, and 545 non-referred adolescents from the general population. The rate of response was lowest for the youngest age group 47%, but increased to 62% with increasing age of the child. The response rate among the adolescents answering the Youth Self Report was 64%. Comparisons with the Child Behavior Checklists from this study are presented with Dutch, American, French, Canadian, German and Chilean samples and show striking similarities in four of these countries on the behaviour/emotional problems reported.

Decrements in cognitive function may already be evident in young children with type 1 diabetes (T1D). Here we report prospectively acquired cognitive results over 18 months in a large cohort of young children with and without T1D. A total of 144 children with T1D (mean HbA1c: 7.9%) and 70 age-matched healthy controls (mean age both groups 8.5 years; median diabetes duration 3.9 years; mean age of onset 4.1 years) underwent neuropsychological testing at baseline and after 18-months of follow-up. We hypothesized that group differences observed at baseline would be more pronounced after 18 months, particularly in those T1D patients with greatest exposure to glycemic extremes. Cognitive domain scores did not differ between groups at the 18 month testing session and did not change differently between groups over the follow-up period. However, within the T1D group, a history of diabetic ketoacidosis (DKA) was correlated with lower Verbal IQ and greater hyperglycemia exposure (HbA1c area under the curve) was inversely correlated to executive functions test performance. In addition, those with a history of both types of exposure performed most poorly on measures of executive function. The subtle cognitive differences between T1D children and nondiabetic controls observed at baseline were not observed 18 months later. Within the T1D group, as at baseline, relationships between cognition (Verbal IQ and executive functions) and glycemic variables (chronic hyperglycemia and DKA history) were evident. Continued longitudinal study of this T1D cohort and their carefully matched healthy comparison group is planned.

To elucidate the effect of early growth patterns on the metabolic sensitivity to adiposity, we examined the relationship between the homeostatic model assessment of insulin resistance (HOMA-IR) and body mass index (BMI) levels at 12 years of age in 101 boys and 91 girls in a birth cohort. Children with an increase in BMI from the ages of 1.5 to 3 years exhibited a greater increase of HOMA-IR per BMI increase at 12 years of age compared to those with a decrease in BMI or stable BMI from 1.5 to 3 years. This suggests that children who show an increase in BMI from 1.5 to 3 years, a period normally characterized by a decreased or stable BMI, are more prone to developing insulin resistance at 12 years of age.

To investigate the gender-related differences in upper airway dimensions and hyoid bone position in Chinese Han children and adolescents (6-18 years) using cone-beam computed tomography (CBCT). CBCT-scans of 119 boys and 135 girls were selected and divided into four groups (group 1: 6-9 years; group 2: 10-12 years; group 3: 13-15 years; group 4: 16-18 years). The airway dimensions including the cross-sectional area (CSA), anteroposterior (AP) and lateral (LAT) width, length (L), mean CSA and volume (VOL) of upper airway segmentations and hyoid bone position including 11 linear and three angular measurements were investigated using Materialism's interactive medical image control system (MIMICS) 16.01 software. Gender-related differences were analyzed by two independent sample t-tests. No gender-related difference was found in values of the facial morphology, airway dimensions and hyoid bone position for group 1 (p > 0.05). The children and adolescents in groups 2, 3 and 4 showed significant gender-related differences in the measurement results of facial morphology, airway dimensions and hyoid bone positions (p < 0.05). What's more, the measurement values of boys were obviously larger than those of girls except some measurements in group 2. The measurements of airway dimensions and hyoid bone positions have gender-related differences in children and adolescents aged 10-18 years. These results could be taken into consideration during orthodontic diagnosis and treatment.

Nationally, motor vehicle crashes are the leading cause of death among youth ages 16 to 20 years. Graduated driver licensing (GDL) laws have been implemented to reduce motor vehicle crashes among teen drivers. Studies have shown decreases in teen crash rates and crash-related fatality rates following enactment of GDL laws. However, GDL laws typically apply to teens only until their 18th birthday; therefore, the effect, if any, that GDL laws have on youth drivers ages 18 to 20 years and whether these programs should be extended to include these older youth warrant further study. The objective of this study was to evaluate the effects of Ohio's 2007 revised GDL law on motor vehicle crashes and crash-related injuries for crashes involving teen drivers ages 16 to 20 years, with a focus on the effects on crashes involving drivers ages 18 to 20 years. Cross-sectional analysis of motor vehicle crashes involving drivers ages 16 to 20 years in Ohio in the pre-GDL (2004-2006) and post-GDL (2008-2010) periods was performed. Descriptive statistics and population-based crash rates for drivers and occupants ages 16 to 20 years were calculated, as well as rate ratios and 95% confidence intervals (CIs) comparing crashes in the pre-GDL and post-GDL periods. Compared with the pre-GDL period, the post-GDL period was associated with lower crash rates for drivers age 16 years (relative risk [RR] = 0.94; 95% CI, 0.90-0.98), age 17 years (RR = 0.90; 95% CI, 0.88-0.93), age 18 years (RR = 0.95; 95% CI, 0.92-0.97), and ages 16-17 years combined (RR = 0.92; 95% CI, 0.90-0.95). Crash rate was higher for the post-GDL period for drivers age 19 years (RR = 1.04; 95% CI, 1.01-1.07), age 20 years (RR = 1.09; 95% CI, 1.05-1.13), and ages 18-20 years combined (RR = 1.02; 95% CI, 1.00-1.03). Unlike previous studies, this investigation used linked data to evaluate the outcomes of all occupants in crashes involving drivers ages 16-20 years. The post-GDL period was associated with lower

Objective: This study was to determine the reliability of age-stratified diagnostic index in differential diagnosis of malignant and benign solitary lesions in the liver using fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18FDG PET/CT). Methods: The enrolled 272 patients with solitary lesions in the liver were divided into three age groups, younger group (under 50 years), middle-aged group (50-69 years), and elderly group (70 years and above). Patients' ages were compared, and the optimal cut-offs of the standard uptake value (SUV) ratio (tumor-to-non-tumor ratio of the SUV), as well as areas under the curves (AUC), were evaluated in terms of malignant and benign lesions in each age group by using receiver operating characteristic (ROC) analysis. Based on optimal cut-offs, the sensitivity, specificity, accuracy were calculated, and the diagnostic accordance rate was compared between each age group and all patients, supported by 18FDG PET/CT imaging data. Results: There was a significant age difference between the malignant and benign groups (t=3.905 p=0.0001). ROC analysis showed that the optimal cut-off value in all patients, younger group, middle-aged group and elderly group was 1.25, 1.17, 1.45 and 1.25 for SUVratio, and 0.856, 0.962, 0.650, 0.973 for AUC. The chi-square test proved that diagnostic accordance rate of 18FDG PET/CT in younger group and elderly group were superior to that in all patients (χ2=13.352, P=0.0003) and (χ2=8.494, P=0.0036). Conversely, overall diagnostic accordance rate in all patient group was higher than that in middle-aged group (χ2=9.057, P=0.0026). Representative 18FDG PET/CT imaging findings are demonstrated. Conclusion: This study indicates that diagnostic optimal cut-offs of SUVratio of liver solitary lesions of 18FDG PET/CT were different in each age group. In addition, the diagnostic performance of SUVratio was better in younger and elderly groups than that in all patients, and was poorer

The objective was to determine the frequency of headache subtypes, according to International Headache Society (IHS) criteria, in a population of children below 6 years visiting a Center for Diagnosis and Treatment of Headache in Youth. Medical records of the children below 6 years at their first visit, admitted for headache between 1997 and 2003, were studied. Headache was classified according to the IHS criteria 2004. Children with less than three headache attacks or less than 15 days of daily headache were excluded. We found 1598 medical records of children who visited our Headache Center in the study period. One hundred and five (6.5%) were children younger than 6 years. The mean age at the first medical control was 4.8+/-1.3 years (range 17-71 months). There were 59 males (56.1%) and 46 females (43.9%). The mean age at onset of headaches was 4.3 years (range 14-69 months). According to the IHS criteria we found 37 cases (35.2%) with migraine, 19 cases (18%) with episodic tension headache, 5 cases (4.8%) with chronic daily headache, 13 cases (12.4%) with primary stabbing headache, 18 cases (17.1%) with post-traumatic headache, 7 cases (6.6%) with other non-dangerous secondary headaches (otorhinolaryngological diseases, post-infectious headaches), 3 cases (2.85%) with dangerous headaches (Arnold-Chiari type 1 malformation, brain tumour) and 9 cases (8.6%) with unclassifiable headaches. Six children (5.7%) reported more than one headache subtype. The prevalence of dangerous headaches was higher than those in school age (chi(2)=4.70, p<0.05). Our study shows some differences in headaches in this population vs. school children. In fact at this age migraine is the most common headache, but we also found an increase of secondary causes among the chronic/recurrent and daily headaches, especially posttraumatic disorders and potentially dangerous headaches. Finally our study shows the highest prevalence of the idiopathic stabbing headache in pre-school children in

The observer-blind, randomized, age-stratified, head-to-head study (NCT00423046) comparing immunogenicity and safety of HPV-16/18 and HPV-6/11/16/18 vaccines in healthy women aged 18-45 y was completed. Five y after vaccination, in subjects from the Month 60 according-to-protocol cohort (seronegative and DNA negative for HPV type analyzed at baseline), serum neutralizing antibody (nAb) responses induced by HPV-16/18 vaccine remained 7.8-fold (18-26-y stratum), 5.6-fold (27-35-y stratum) and 2.3-fold (36-45-y stratum) higher than those induced by HPV-6/11/16/18 vaccine for HPV-16. For HPV-18, the fold differences were 12.1, 13.0 and 7.8, respectively. At Month 60, all (100%) subjects in HPV-16/18 vaccine group and the majority (95.7%-97.5%) in HPV-6/11/16/18 vaccine group were seropositive for HPV-16. For HPV-18, the majority (98.1%-100%) of subjects in HPV-16/18 vaccine group were seropositive; however, seropositivity rates in HPV-6/11/16/18 vaccine group decreased considerably (61.1%-76.9%) across the 3 age strata. In the total vaccinated cohort (received ≥ 1 dose regardless of baseline HPV serostatus and DNA status), geometric mean titers for anti-HPV-16 and anti-HPV-18 nAb were higher in HPV-16/18 vaccine group than in HPV-6/11/16/18 vaccine group. Based on the 5-y data, piece-wise and modified power-law models predicted a longer durability of nAb response for HPV-16/18 vaccine compared to HPV-6/11/16/18 vaccine. Beyond the differences apparent between the vaccines in terms of immunogenicity and modeled persistence of antibody responses, comparative studies including clinical endpoints would be needed to determine whether differences exist in duration of vaccine-induced protection.

Background Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. Objective To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. Design A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. Setting and Participants A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Main Outcome Measures Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Results Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Conclusions Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits. PMID:12796242

The majority of tobacco use emerges in individuals before they reach 21 years of age, and many adult distributors of tobacco to youths are young adults aged between 18 and 20 years. Raising the tobacco sales minimum age to 21 years across the United States would decrease tobacco retailer and industry sales by approximately 2% but could contribute to a substantial reduction in the prevalence of youths' tobacco use and dependency by limiting access.

Measles-mumps-rubella (MMR) vaccinations have been offered to Finnish children at 14-18 months and 6 years of age. In May 2011, the recommended age for the first vaccine dose was lowered to 12 months because of the European measles epidemic. Fingertip capillary blood samples were collected from 3-year-old Finnish children vaccinated once with MMR vaccine at 11-19 months of age. The immunoglobulin G (IgG) antibodies to all 3 MMR antigens were measured with enzyme-linked immunosorbent assay. Neutralizing antibodies and the avidity of antibodies were measured for measles virus. From April through October 2013, 187 children were enrolled. Equally high proportions of the samples were seropositive for measles virus, mumps virus, or rubella virus antibodies, and there were no significant differences in the IgG antibody concentrations in children vaccinated at 11-13 months of age, compared with those vaccinated at 17-19 months of age. However, among children vaccinated at 11-13 months of age, boys had lower antibody concentrations than girls. Neutralizing measles virus antibody titers were above the threshold for protective immunity in all 78 samples analyzed. The measles virus antibody avidity indexes were high for all children. MMR induces similar antibody responses in 12-month-old children as compared to 18-month-old children, but in boys increasing age appears to improve the antibody responses. © The Author 2016.

Thyroid Cancer Detection by Ultrasound Among Residents Ages 18 Years and Younger in Fukushima, Japan: 2011 to 2014

PubMed Central

Tokinobu, Akiko; Yamamoto, Eiji; Suzuki, Etsuji

2016-01-01

Background: After the Great East Japan Earthquake and Tsunami in March 2011, radioactive elements were released from the Fukushima Daiichi Nuclear Power Plant. Based on prior knowledge, concern emerged about whether an increased incidence of thyroid cancer among exposed residents would occur as a result. Methods: After the release, Fukushima Prefecture performed ultrasound thyroid screening on all residents ages ≤18 years. The first round of screening included 298,577 examinees, and a second round began in April 2014. We analyzed the prefecture results from the first and second round up to December 31, 2014, in comparison with the Japanese annual incidence and the incidence within a reference area in Fukushima Prefecture. Results: The highest incidence rate ratio, using a latency period of 4 years, was observed in the central middle district of the prefecture compared with the Japanese annual incidence (incidence rate ratio = 50; 95% confidence interval [CI] = 25, 90). The prevalence of thyroid cancer was 605 per million examinees (95% CI = 302, 1,082) and the prevalence odds ratio compared with the reference district in Fukushima Prefecture was 2.6 (95% CI = 0.99, 7.0). In the second screening round, even under the assumption that the rest of examinees were disease free, an incidence rate ratio of 12 has already been observed (95% CI = 5.1, 23). Conclusions: An excess of thyroid cancer has been detected by ultrasound among children and adolescents in Fukushima Prefecture within 4 years of the release, and is unlikely to be explained by a screening surge.

The objective of this study was to investigate the relationships between overweight and high waist circumference and cardiovascular risk factors in children. We carried out a secondary analysis of data from 1,944 participants of the 'National Diet and Nutrition Survey: young people aged 4-18 years'. Blood pressure and blood lipid levels were compared in overweight versus non-overweight and high versus low waist circumference groups. Overweight was defined using international cut-offs for body mass index. High waist circumference was defined as >or= 91st percentile of UK waist circumference charts. Analyses were done separately by sex and age group (4-10 and 11-18 years for overweight, and 11-17 years for waist circumference). Overweight and high waist circumference were associated with increased systolic blood pressure, mean arterial pressure, low-density lipoprotein cholesterol (LDLC) and triacylglycerol, and decreased high-density lipoprotein cholesterol (HDLC). Those who were both overweight and had a high waist circumference had the highest blood pressure, plasma LDLC and triacylglycerol, and the lowest plasma HDLC. Overweight and high waist circumference were associated with increased blood pressure and a less favourable lipid profile. Children who were both overweight and had a high waist circumference had the most unfavourable cardiovascular risk profile. Both measurements may be useful in identifying children with increased health risks.

Infliximab (IFX) is efficacious for induction and maintenance of remission in pediatric patients with moderate-to-severe inflammatory bowel disease (IBD). It has, however, not been studied in patients 7 years old and younger. Our aim was to characterize efficacy and safety of IFX therapy in this cohort. This was a retrospective study of patients with IBD ages 7 years and younger, treated with IFX between 1999 and 2011. Medical records were reviewed for age of diagnosis, disease phenotype, therapy, surgery, IFX infusion dates, dose, and intervals. Outcome measures included physician global assessment, corticosteroid requirement, and adverse events. Thirty-three children (ages 2.4-7 years) were included. Twenty patients had Crohn disease, 4 had ulcerative colitis, and 9 had indeterminate colitis. Maintenance of IFX therapy at 1, 2, and 3 years was 36%, 18%, and 12%, respectively. Patients of age 5 years and younger had the lowest rates of maintenance of therapy at 25% at year 1, and 10% at years 2 and 3 combined. Nine percent of all of the patients demonstrated response measured by the physician global assessment and were steroid free at 1 year. There were 8 infusion reactions. There were no malignancies, serious infections, or deaths. IFX demonstrated a modest response rate and a low steroid-sparing effect in patients with IBD 7 years old and younger. Although this is a limited study, there appears to be a trend for decreased sustained efficacy with IFX in this age group, particularly in children 5 years old and younger, when compared with the previously published literature in older children.

Chronic rhinitis (CR) is one of the most common causes accounting for lost-school days, absenteeism and resource utilization in pediatric patients. Distinction between common causes of CR, allergic (AR)and non-allergic rhinitis (NAR), based upon clinical features is critical, especially in primary care settings or facilities with lack of allergen sensitivity testing, as management strategies differ considerably. The current study elucidates clinical factors, particularly facial features associated with AR and NAR using a large cohort. In a retrospective cohort analysis of pediatric patients aged 6-18 years, we assessed patient demographics, clinical symptoms, and signs associated with allergic rhinitis using multivariable regression techniques. Overall, 1490 patients (mean age: 10.11 ± 3.31 years; 48% female; 69% AR and 31% NAR) were included in the study. In multivariable regression analysis, major clinical features associated with AR were: sneezing (OR: 3.53; 95% CI: 2.35-5.32; p < 0.001), rhinorrhea (OR: 1.77; 95% CI: 1.18-2.66; p = 0.006), nasal itching (OR: 17.88; 95% CI: 11.92-26.83; p < 0.001), horizontal nasal crease (OR: 5.09; 95% CI: 1.29-20.01; p = 0.020) and conjunctivitis (OR: 4.66; 95% CI: 3.28-6.62; p < 0.001). On the contrary, we noted presence of Dennie-Morgan fold (OR: 1.67; 95% CI: 1.11-2.56; p = 0.014), moderate to severe persistent or intermittent symptoms to be likely associated with NAR than AR. In pediatric patients presenting with symptoms of rhinitis, facial hallmarks serve as an adjunct to sensitivity testing in establishing a diagnosis as well as differentiating between NAR from AR, albeit individualized upon patient history and clinical features.

Birth order modifies the effect of IL13 gene polymorphisms on serum IgE at age 10 and skin prick test at ages 4, 10 and 18: a prospective birth cohort study

PubMed Central

2010-01-01

Background Susceptibility to atopy originates from effects of the environment on genes. Birth order has been identified as a risk factor for atopy and evidence for some candidate genes has been accumulated; however no study has yet assessed a birth order-gene interaction. Objective To investigate the interaction of IL13 polymorphisms with birth order on allergic sensitization at ages 4, 10 and 18 years. Methods Mother-infant dyads were recruited antenatally and followed prospectively to age 18 years. Questionnaire data (at birth, age 4, 10, 18); skin prick test (SPT) at ages 4, 10, 18; total serum IgE and specific inhalant screen at age 10; and genotyping for IL13 were collected. Three SNPs were selected from IL13: rs20541 (exon 4, nonsynonymous SNP), rs1800925 (promoter region) and rs2066960 (intron 1). Analysis included multivariable log-linear regression analyses using repeated measurements to estimate prevalence ratios (PRs). Results Of the 1456 participants, birth order information was available for 83.2% (1212/1456); SPT was performed on 67.4% at age 4, 71.2% at age 10 and 58.0% at age 18. The prevalence of atopy (sensitization to one or more food or aeroallergens) increased from 19.7% at age 4, to 26.7% at 10 and 41.1% at age 18. Repeated measurement analysis indicated interaction between rs20541 and birth order on SPT. The stratified analyses demonstrated that the effect of IL13 on SPT was restricted only to first-born children (p = 0.007; adjusted PR = 1.35; 95%CI = 1.09, 1.69). Similar findings were noted for firstborns regarding elevated total serum IgE at age 10 (p = 0.007; PR = 1.73; 1.16, 2.57) and specific inhalant screen (p = 0.034; PR = 1.48; 1.03, 2.13). Conclusions This is the first study to show an interaction between birth order and IL13 polymorphisms on allergic sensitization. Future functional genetic research need to determine whether or not birth order is related to altered expression and methylation of the IL13 gene. PMID:20403202

Objective: To analyze the rates on prevalence, awareness, status on treatment and control of type 2 diabetes mellitus among Chinese premenopausal women aged 18-49, in 2013. Methods: Data on China Chronic and Non-Communicable Disease Surveillance in year 2013 was used for analysis. Source of data covered 302 surveillance points which were selected by Multi-stage cluster random sampling method that including 176 534 adults over 18 years of age, with 46 674 premenopausal women aged 18-49. Plasma glucose and hemoglobin A1c levels were determined after a 10-hour overnight fast for all the participants, before a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes was defined according to the 1999 WHO diagnostic criteria-fasting blood glucose level as ≥7.0 mmol/L and/or 2 hours oral glucose tolerance test (OGTT-2 h) level as ≥11.1 mmol/L. After being weighed, according to complex sampling scheme and post-stratification, the sample was used to estimate the rates of prevalence, awareness, treatment and control of type 2 diabetes mellitus by age, education, urban and rural areas, and geographic locations. Results: The overall prevalence of type 2 diabetes mellitus was 5.6% among the Chinese premenopausal women aged 18-49. No statistical difference on the prevalence rates (5.7% and 5.4%, respectively) was seen, between participants from the rural or the urban areas. Prevalence rates in the eastern, central or western geographic areas were 5.8%, 6.2% and 4.4% respectively. The rates of awareness, treatment and control of diabetes appeared as 29.3%, 27.9% and 29.4% in childbearing women aged 18-49. The rate of treatment was 95.4% among those who knew their diabetic situation in childbearing women aged 18-49 years. The control rate of diabetes was 38.9% among those who had taken measures to control glucose, in 18-49-year-old childbearing women. The rate of awareness on diabetes in childbearing

The aim of this study was to investigate associations of yogurt and dairy consumption with energy, macronutrient, calcium, and vitamin D intakes, and associations with indicators of overweight/obesity in U.S. children in the National Health and Nutrition Examination Survey (NHANES 2005-2008). Using 24-hour recall data, children 8-18 years of age were classified to dairy consumption groups of <1, 1 to <2, or 2+ dairy servings, and yogurt consumers were those who reported eating yogurt during at least one of two dietary intake interviews. NHANES anthropometric measurements were used, and BMI and BMI-for-age percentiles were calculated. Yogurt and dairy consumption were associated with higher intakes of calcium, vitamin D and protein. Yogurt intake was associated with lower total fat and saturated fat intakes and body fat as measured by subscapular skinfold thickness. This study supports consumption of yogurt and higher amounts of dairy as eating patterns associated with greater intake of specific shortfall nutrients, and lower body fat in U.S. children.

This follow-up study reports on cerebral MRI findings in 20 very-low-birthweight (VLBW) infants without disabilities at age 1 year in relation to motor, intellectual, and perceptual function at age 6 years. MRI findings, anthropometrics, and Bayley Scales of Infant Development scores at age 1 year as predictors of psychomotor status at age 6 years are also evaluated and compared. Outcome parameters were the Peabody Developmental Motor Scales and the Wechsler Preschool and Primary Scale of Intelligence. The results show that infants with myelin hyperintensities including the centrum semiovale or with occipital hyperintensities with associated ventricular dilatation at age 1 scored lower on the Peabody Gross Motor Locomotion Scale at age 6 than infants with normal myelination or with isolated occipital hyperintensities. This may indicate damage to motor fibers caused by perinatal periventricular leukomalacia. No relation was found between abnormal MRI findings at age 1 and later fine motor, intellectual, and perceptual function. Comparing different age 1-year predictors, an abnormality score defined by MRI was used as an independent predictor of gross motor locomotion function at age 6 years. However, the Bayley Mental Development Index scores and weight at age 1 were more important predictors of later motor and intellectual outcome, respectively, than MRI findings. It is recommended that cerebral MRI should not be used routinely to examine VLBW infants without disabilities at 1 year of age.

Objective Poor nutrition is thought to predispose to externalizing behavior problems, but to date there appear to have been no prospective longitudinal studies testing this hypothesis. This study assessed whether 1) poor nutrition at age 3 years predisposes to antisocial behavior at ages 8, 11, and 17 years, 2) such relationships are independent of psychosocial adversity, and 3) IQ mediates the relationship between nutrition and externalizing behavior problems. Method The participants were drawn from a birth cohort (N=1,795) in whom signs of malnutrition were assessed at age 3 years, cognitive measures were assessed at ages 3 and 11 years, and antisocial, aggressive, and hyperactive behavior was assessed at ages 8, 11, and 17 years. Results In relation to comparison subjects (N=1,206), the children with malnutrition signs at age 3 years (N=353) were more aggressive or hyperactive at age 8 years, had more externalizing problems at age 11, and had greater conduct disorder and excessive motor activity at age 17. The results were independent of psychosocial adversity and were not moderated by gender. There was a dose-response relationship between degree of malnutrition and degree of externalizing behavior at ages 8 and 17. Low IQ mediated the link between malnutrition and externalizing behavior at ages 8 and 11. Conclusions These results indicate that malnutrition predisposes to neurocognitive deficits, which in turn predispose to persistent externalizing behavior problems throughout childhood and adolescence. The findings suggest that reducing early malnutrition may help reduce later antisocial and aggressive behavior. PMID:15514400

Nutritional disorders in childhood may cause a decline in motor abilities and increased morbidity and mortality in adulthood. To assess the association between nutritional status and motor abilities. A cross-sectional study was performed that included 12,872 children aged between 6 and 18 years who underwent a clinical evaluation and various physical tests. Among the children, 66% had a Tanner maturation stage 1 and 2, 6% were under-nourished, and 12.2% were at risk of overweight and obesity. The obese children had a decrease in aerobic power (in 2.72 mL O2 kg(-1)·min(-1); 95%CI: 1.89 to 3.56; P<.001), speed (0.14m·sec; 95%CI: 0.06 to 0.22; P<.001), explosive strength (0.10 m; 95%CI: 0.06 to 0.13; P<.001), agility, strength endurance and balance. Under-nourished children showed a decrease in speed (0.13 m·sec; 95%CI: 0.06 to 0.20; P<.001), explosive strength (0.04 m; 95%CI: 0.01 to 0 07; P<.004), and strength endurance. There was an association between nutritional status and motor abilities in the children included in this study. Obese children showed the worst results in physical tests, and the under-nourished ones showed a decrease in speed, explosive strength and strength endurance.

Meningococcal carriage is a prerequisite for invasive infection. This cross-sectional study assessed the pharyngeal carriage prevalence in healthy subjects aged 1-24 years in Embu das Artes city, São Paulo, Brazil. Pharyngeal swabs were examined for the presence of Neisseria meningitidis. The isolates were tested for different serogroups using agglutination and polymerase chain reaction. A logistic regression model assessed any independent association between Neisseria meningitidis carriage and various risk factors. A total of 87/967 subjects (9%, 95% Confidence Interval (CI): 7.3-11.0) tested positive for N. meningitidis: 6.2% (95% CI: 3.8-9.4) in 1-4 years, 8.5% (95% CI: 5.1-13.0) in 5-9 years, 12.5% (95% CI: 7.8-18.6) in 10-14 years, 12.6% (95% CI: 7.4-19.7) in 15-19 years and 9% (95% CI: 4.9-14.9) in 20-24 years age groups. Highest carriage prevalence was observed in adolescents 10-19 years old. Serogroup C was predominant (18.4%) followed by serogroup B (12.6%). The 15-19 years age group showed a significant association between number of household members and carriers of N. meningitidis. This cross-sectional study is the first in Brazil to evaluate meningococcal carriage prevalence and associated factors in a wide age range. Copyright © 2017 Sociedade Brasileira de Infectologia.

To understand the current status of liquid beverage consumption of adult residents in 15 provinces and cities in China, and discuss relevant factors that may affect the consumption of liquid beverage of adult residents, and provide data support to guide the rational consumption of liquid beverage. Using data from China Nutritional Transition Cohort Survey in 2015 on the subjects aged 18 to 59 years old in 15 provinces and cities in China with complete 24-hour-dietary for 3 days and food consumption frequency method, chi-square was used to analyze liquid beverage consumption rate, nonparametric test was used to analyze beverage consumption intake levels of different gender, age, education degree, urban and rural areas, income, region. The factors affecting the consumption of liquid beverage were analyzed by Logistic regression model. The result of complete 24-hour-dietary for 3 days showed that the consumption rate of liquid beverage was 2. 8% and the 99 th consumption of liquid beverage was 93. 3 g/d for adult residents in 15 provinces and cities in 2015. The consumption rate and P99 intake of liquid beverage increased gradually with the increase of educational degree and income; the city was higher than the rural areas; the eastern was higher than the central and west region. Logistic analysis showed that the distribution of education, urban and rural areas and region were the influencing factors of whether adult residents drank liquid beverage. The 50 th consumption of liquid beverage in the consumer group was 70. 0 g/d. Among them, 18-44 years old youth group was higher than 45-59 years old middle age group; junior middle school education was highest lowest; the rural was higher than the city; the central was higher than west and east region. The result of food consumption frequency showed that 25. 8% of adults were reported consumed liquid beverage in 2015. The main types of beverages were fruit juice and fruit juice beverages, carbonated drinks, accounting for

In order to assess if any differences exist in children germ cell tumours depending on age, we compared some features of germ cell tumours in two age groups:younger than 10 and between 11 and 18 years. Data of 146 patients with germ cell tumours treated in 15 Polish paediatric oncology departments between 1995 and 2005 were evaluated. They were divided into two groups: 76 children 0-10 years old (group I) and 70 patients 11-18 years old (group II). Tumour morphology, sex of patients, primary tumour and metastases localization, disease stage, biochemical markers, treatment response, disease relapse and long survival were analyzed. Every patient was treated according to the TGM 95 protocol. In group 1, 67 tumours were assessed histologically. 64%t tumours had homogenous structure with yolk sac tumour in predominance and 36% were mixed. Yolk sac tumour (YST) or teratoma as components of mixed tumours were the most commonly found. In older group 64 tumours were examined, 41% were homogenous, and seminoma/dysgerminoma predominated. In 59% mixed tumours the most common components were YST embryonal carcinoma and teratoma. The most common primary site in group I was the sacrococcygeal region while in group II - the gonads. Disseminated disease was recognized mostly in older children. Among two evaluated serum markers, AFP was increased mostly in younger patients (76% vs 44%), and 3HCG in older group (40% vs 9%). Treatment response was comparable in both groups. Two relapses were observed in each group. Poor outcome was noted in 17/140 analyzed patients: 9 (12%) in group I and 8 (11%) in group II. In 12 of patients with poor outcome the cause of death was progression and in 5 of them - treatment complications. 1. Germ cell tumours in younger and older children differ in histology, primary localization and serum level of biochemical markers. 2. In older patients germ cell tumours are recognized more frequently in advanced clinical stages. 3. Treatment response was

This study describes trends in dietary diversity and food intake over 12 years according to age at first participation in the study. Prospective cohort study. The National Institute for Longevity Sciences - Longitudinal Study of Aging, a community-based study. Participants included 922 men and 879 women who participated in the first study-wave (age, 40-79 years) and also participated in at least one study-wave from the second to seventh study-wave. Study-waves were conducted biennially. Dietary intake was calculated from 3-day dietary records with photographs. Dietary diversity was determined using the Quantitative Index for Dietary Diversity based on food intake. A mixed-effects model was used to estimate linear changes in dietary diversity and food intake over 12 years according to age at first study-wave. Mean (standard deviation (SD)) follow-up time and number of study-wave visits were 9.5 (3.7) years and 5.4 (1.8), respectively. Mean (SD, range) dietary diversity score was 0.86 (0.06, 0.52-0.96) in men and 0.88 (0.04, 0.66-0.96) in women, respectively. Fixed effects for interactions of age and time with dietary diversity score were statistically significant (p<0.05). The slope of dietary diversity among men aged 40 to 55 years increased (40-year-old slope = 0.00093/year, p<0.01; 55-year-old slope = 0.00035/year, p=0.04), with a decreasing trend started at 65 years old, although this trend was not significant (65-year-old slope = -0.00003/year, p=0.88; 79-year-old slope = -0.00057/year, p=0.21). The slope of dietary diversity among women aged 40 to 44 years increased (40-year-old slope = 0.00053/year, p=0.02; 44-year-old slope = 0.00038/year, p=0.04), whereas the slope of dietary diversity among women aged 63 to 79 years decreased (63-year-old slope = -0.00033/year, p=0.03; 79-year-old slope = -0.00092/year, p<0.001). Fruit, milk and dairy intake decreased in men around their 60s; milk and dairy intake decreased in women around their 50s; and beans and fruit

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.

In this study, seroprevalence of mumps, varicella and rubella was investigated in 803 unvaccinated children in eastern Turkey whose ages ranged between 1 and 16 years. Mumps IgG, varicella IgG and rubella IgG antibody levels in all children were studied by enzyme-linked immunosorbent assay (ELISA) method. Information regarding socioeconomic characteristics, number of siblings and disease history was gathered for each participant. No significant difference in seropositivity was detected between girls and boys. Seroprevalence of mumps increased with age, with a seropositivity rate of 29.9% in children aged 1-4 years and of 88.8% in those aged 13-16 years. Seroprevalence of varicella increased with age, with a seropositivity rate of 26.8% in children aged 1-4 years and of 90.3% in those aged 13-16 years. Seroprevalence of rubella also increased with age, with a seropositivity rate of 47.3% in the children aged 1-4 years and of 89.2% in those aged 13-16 years. There was a statistically significant increase in the rate of seropositivity with advancing age through the group of 13-16 years old (p < 0.05). In conclusion, in order to avoid mumps, varicella and rubella diseases and their possible complications, children should be vaccinated against these three diseases before the age of two, since seroprevalence increases with age.

Given the degree of HIV epidemic among women and the current antiretroviral therapy (ART) scale up in Ethiopia; considering the issue of fertility is vital to ensure the delivery of integrated reproductive health along with prevention services provided to positive women. This study was aimed to assess fertility intentions of women living with HIV attending public health institutions (hospitals & health centers) in Addis Ababa, Ethiopia. Institution based cross sectional survey was conducted, among 1855 HIV positive, women aged 18-49 years selected from different public health facilities in Addis Ababa; from June to October 2012. Information was gathered by using interviewer administered questionnaires. Data were double entered in EPI Info version 3.5.2 software, cleaned finally exported to IBM SPSS statistics version 20 for analysis. Logistic regression models were used to predict the association of study variables and adjusted for possible confounders. Overall, 44% of women reported fertility intention. ART users had higher fertility intention (AOR; 1.26, 95%CI; 1.01 to 1.60) than ART naïve. In addition to this, having partner being on sexual relationship, young age, being single and having fewer or no children were found to be predictors of fertility intentions. The presence of ART, improvement of health condition and the influence of husband were the main reasons for childbearing intentions of women in the study area. A considerable proportion of women reported fertility intention. There was an association between fertility intentions and ART use. It is important for health care providers and policy makers to strengthen the fertility need of HIV positive women along with HIV care so that women may decide freely and responsibly on their fertility issues.

This manuscript presents data on the persistence of Hemagglutination Inhibition (HI) immune response against the A/California/7/2009 strain, six and 12 mo after adults received one dose (n = 138) or two doses (n = 102; 21 d apart) of a 3.75 µg Hemagglutinin antigen AS03-adjuvanted H1N1 2009 vaccine (NCT00968526). Two hundred forty subjects (18-60 y: 120;>60 y: 120) were vaccinated. Immunogenicity end points were based on the European licensure criteria for pandemic influenza vaccines. Exploratory analyses assessed the cell-mediated immune response (CMI) up to Month 12 and the influence of previous influenza vaccination on persistence of immune response. At Month 6, the CHMP criteria were met in subjects aged 18-60 y who received one or two vaccine doses and in subjects aged>60 y who received two vaccine doses. At Month 12, the CHMP criteria were met only in subjects aged 18-60 y who received two vaccine doses. Persistence of HI immune response against the vaccine strain was higher in subjects without prior influenza vaccination. Exploratory analyses showed that two doses of the H1N1 2009 vaccine induced persistence of H1N1-specific CD4+ T cells up to Month 6 and memory B cells up to Month 12. In conclusion, HI immune responses persisted up to 12 mo after vaccination with one-dose and two-dose regimens of the AS03-adjuvanted 3.75 µg HA H1N1 2009 pandemic influenza vaccine, although not all three CHMP guidance criteria for both groups were met at Month 6 and Month 12. The CD4+ T cell and B cell responses also persisted up to Month 12.

Height is required for the assessment of growth and nutritional status, as well as for predictions and standardization of physiological parameters. To determine whether arm span, mid-upper arm and waist circumferences and sum of four skinfolds can be used to predict height, the relationships between these anthropometric variables were assessed among Ellisras rural children aged 8-18 years. The following parameters were measured according to the International Society for the Advancement of Kinathropometry: height, arm span, mid-upper arm circumference, waist circumference and four skinfolds (suprailiac, subscapular, triceps and biceps). Associations between the variables were assessed using Pearson correlation coefficients and linear regression models. Ellisras Longitudinal Study (ELS), Limpopo Province, South Africa. Boys (n 911) and girls (n 858) aged 8-18 years. Mean height was higher than arm span, with differences ranging from 4 cm to 11·5 cm between boys and girls. The correlation between height and arm span was high (ranging from 0·74 to 0·91) with P<0·001. The correlation between height and mid-upper arm circumference, waist circumference and sum of four skinfolds was low (ranging from 0·15 to 0·47) with P<0·00 among girls in the 15-18 years age group. Arm span was found to be a good predictor of height. The sum of four skinfolds was significantly associated with height in the older age groups for girls, while waist circumference showed a negative significant association in the same groups.

To determine the relationship between child marriage (before age 18 years) and morbidity and mortality of children under 5 years of age in Pakistan beyond those attributed to social vulnerabilities. Nationally-representative cross-sectional observational survey data from Pakistan Demographic and Health Survey, 2006-2007 was limited to children from the past 5 years, reported by ever-married women aged 15-24 years (n = 2630 births of n = 2138 mothers) to identify differences in infectious diseases in past 2 weeks (diarrhea, acute respiratory infection [ARI], ARI with fever), under 5 years of age and infant mortality, and low birth weight by early (<18) vs adult (≥ 18) age at marriage. Associations between child marriage and mortality and morbidity of children under 5 years of age were assessed by calculating adjusted OR using logistic regression models after controlling for maternal and child demographics. Majority (74.5%) of births were from mothers aged <18 years. Marriage before age 18 years increased the likelihood of recent diarrhea among children born to young mothers (adjusted OR = 1.59; 95% CI: 1.18-2.14). Even though maternal child marriage was associated with infant mortality and mortality of children under 5 years of age in unadjusted models, association was lost in the adjusted models. We did not find a relation between girl-child marriage and low birth weight infants, and ARI. Girl-child marriage increases the likelihood of recent diarrhea among children born to young mothers. Further qualitative and prospective quantitative studies are needed to understand the factors that may drive child morbidity and mortality among those married as children vs adults in Pakistan.

To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years. Copyright © 2015 Elsevier Inc. All rights reserved.

Most head circumference growth references are useful during the first years of life, but they are also useful for older children when screening for developmental, neurological, and genetic disorders. We aimed to develop head circumference growth reference charts for age, height, and waist circumference for Turkish children aged 5-18 years. Head circumference, height, and waist circumference measurements were obtained from 5079 students aged 5-18 years from İzmit, Kocaeli Province, Turkey. The LMS method was used to construct reference centile curves. Head circumference measurements were strongly correlated with height (r=0.74), weight (r=0.76), and waist circumference (r=0.68). The mean head circumference values for boys were larger than those for girls at all ages. Compared with data from the United States, the World Health Organization, and other studies from Turkey, our data showed a decrease in head circumference at all ages for both sexes. Local growth charts can be used to evaluate head circumference growth in older Turkish children and adolescents.

We sought to present the epidemiology of idiopathic pulmonary fibrosis (IPF) in adults 18-64 years old in the USA.From adults aged 18-64 years in a large administrative claims data in 2004-2010, patients with IPF were identified using diagnosis codes. We estimated annual incidence and cumulative prevalence of IPF over time, and examined potential risk factors for the IPF diagnosis.The annual cumulative prevalence increased steadily in the first few years (from 13.4 cases per 100 000 persons in 2005 to 18.2 cases in 2010 per 100 000 persons), which is likely due to a methodological reason, while the annual incidence of IPF decreased over time (from 7.9 cases per 100 000 person-years in 2005 to 5.8 cases in 2010 per 100 000 person-years). The overall decrease was mainly driven by a decreasing trend in the younger patients (aged 18-44 years), while the incidence in older patients remained stable. Consistent trends were observed in subgroups defined by previously published more restrictive algorithms for diagnosis. Older age and male sex were associated with a higher incidence of disease (p<0.05).In US adults younger than 65 years, we observed a decreasing incidence of IPF over time which may partially explain the plateau of cumulative prevalence in the last few years of our data.

Objective: To explore the prevalence of physical activity time <1 hour and related factors in students aged 9-22 years in China. Methods: A total of 220 159 students (110 039 boys and 110 120 girls) aged 9-22 years who completed the questionnaire of physical activity and lifestyle behaviors were selected from " 2014 National Physical Fitness and Health Surveillance" for the current study. All the participants were divided into 2 groups, i.e. physical activity time <1 hour and physical activity time ≥1 hour according the suggestion of Central Government, stratified by age and gender. χ (2) tests were used to compare the difference in the prevalence of physical activity time <1 hour between boys and girls in every age groups. Univariate and multivariate log-binomial regression models were used to explore the factors that influenced the prevalence of physical activity time <1 hour. Results: The boy's prevalence of physical activity time <1 hour was 73.3%, with the lowest (57.0%) in 9-years-old group, and highest (82.5%) in 18 years old group. The girl's prevalence of physical activity time <1 hour was 79.1%, with the lowest (60.1%) in 9-years-old group, and highest (89.8%) in 21 years old group. Overall, The prevalence of physical activity time <1 hour was significantly higher in girls than in boys ( P <0.001), and the prevalence were significantly higher in girls than in boys in all the age groups ( P <0.001), and it was observed that the prevalence of physical activity <1 hour increased with age in both boys and girls ( P <0.001). Multivariate log-binomial regression model found that being girl ( PR =1.05, 95 %CI : 1.05-1.06), parents' disliking children to participate physical activity ( PR =1.08, 95 % CI : 1.07-1.09), heavy homework ( PR =1.13, 95 % CI : 1.12-1.14), long homework time ( PR =1.08, 95 %CI : 1.07-1.08), long time spending on electronic screen watching ( PR =1.01, 95 %CI : 1.00-1.01) and disliking physical class ( PR =1.11, 95 %CI : 1.10-1

The Copenhagen Child Cohort, CCC 2000, was established to investigate developmental psychopathology prospectively from birth in a general population. A random sample of 211 children from the CCC 2000 was investigated when the children were 1(1/2) years of age. The prevalence and associates of mental health problems and psychopathology were studied by clinical and standardised strategies, including videotape recordings, parent interviews and the following instruments: The Child Behavior Check List 1(1/2)-5 (CBCL 1(1/2)-5), The Infant Toddler Symptom Check List (ITSCL), Checklist for Autism in Toddlers (CHAT), Bayley Scales of Infant Development II (BSID II), The Parent Child Early Relationship Assessment (PC ERA) and Parent Infant Relationship Global Assessment Scale (PIR-GAS). Mental health problems according to International Classification of Diseases (ICD-10) and Diagnostic Classification Zero to Three (DC 0-3) diagnoses were found in 16-18% of 1(1/2)-year-old children. Most common were disturbances of emotion, behaviour and eating and the DC 0-3 diagnosis of regulatory disorder. Parent-child relationship disturbances were found in 8%. High psychosocial risk was significantly associated with emotional and behavioural disorders (OR 3.1 95% (1.2-8.1)) and disturbed parent-child relationship (OR 5.0 95% (1.6-16.0)). The strongest association of risk was found between relationship disorders and emotional and behavioural disorders (OR 11.6 95% (3.8-37.5)). The prevalence and distribution of psychopathology in 1(1/2)-year-old children seem to correspond to the distributions among older children. Disturbances in parent-child relationship have a key position in the risk mechanisms in early child psychopathology.

Originating in the 1960s, the Achenbach System of Empirically Based Assessment (ASEBA) comprises a family of instruments for assessing problems and strengths for ages 1½-90+ years. To provide an overview of the ASEBA, related research, and future directions for empirically based assessment and taxonomy. Standardized, multi-informant ratings of transdiagnostic dimensions of behavioral, emotional, social, and thought problems are hierarchically scored on narrow-spectrum syndrome scales, broad-spectrum internalizing and externalizing scales, and a total problems (general psychopathology) scale. DSM-oriented and strengths scales are also scored. The instruments and scales have been iteratively developed from assessments of clinical and population samples of hundreds of thousands of individuals. Items, instruments, scales, and norms are tailored to different kinds of informants for ages 1½-5, 6-18, 18-59, and 60-90+ years. To take account of differences between informants' ratings, parallel instruments are completed by parents, teachers, youths, adult probands, and adult collaterals. Syndromes and Internalizing/Externalizing scales derived from factor analyses of each instrument capture variations in patterns of problems that reflect different informants' perspectives. Confirmatory factor analyses have supported the syndrome structures in dozens of societies. Software displays scale scores in relation to user-selected multicultural norms for the age and gender of the person being assessed, according to ratings by each type of informant. Multicultural norms are derived from population samples in 57 societies on every inhabited continent. Ongoing and future research includes multicultural assessment of elders; advancing transdiagnostic progress and outcomes assessment; and testing higher order structures of psychopathology.

To summarize the data on the prevalence of type 1 diabetes mellitus among 15-34-year-aged Lithuania inhabitants (1991-2010). New prevalent cases consist of growing-up patients with diabetes onset in childhood, i.e., up to 14 years, new onset 15-34-year-aged type 1 diabetic patients Lithuanian inhabitants, and immigrants. The data on type 1 diabetes was collected with the help of general practitioners and regional endocrinologists in Lithuania. On 31 December 1991, there were 1202 adolescent and adult 15-34-year-aged patients with type 1 diabetes mellitus or 103.59 per 100,000 inhabitants of the same age group (95% Poisson CI 97.90-109.62), and at the end of 2010 - 1533 or 187.80 (178.63-197.44), respectively in Lithuania. During 19-year period the mean increase of type 1 diabetic patients was 1.25±1.94% per year or 1.47±2.74 per 100,000 inhabitants per mean year of the study period (for males 1.42±2.14% or 1.69±3.05/100,000 and for females 1.05±1.99%, or 1.24±2.92/100,000). Regression-based linear trends showed that the prevalence of type 1 diabetes mellitus in 15-34-year-age group had a tendency to increase among males (r=0.953; p<0.001) and females (r=0.970; p<0.001). The age adjusted prevalence frequencies for males and females in 1991 were correspondingly 102.81/100,000 and 104.55/100,000, and in 2010 - 193.75 and 182.01.

Motor vehicle crashes are the leading cause of death for teens and young adults in the United States. Graduated driver licensing (GDL) systems were designed to protect young novice drivers by limiting their exposure to specific risks while they gain experience driving. In the United States, most states' GDL systems only apply to new drivers younger than 18. Some experts suggest that GDL might encourage young people to wait until age 18 to obtain a license, to avoid GDL requirements, resulting in older teenagers having less driving experience and higher crash risk than they might have had without GDL. This study examined the prevalence and timing of licensure among young adults, and explored factors associated with delaying licensure among those not licensed before age 18. An online questionnaire was completed by 1,039 persons aged 18-20 years, recruited from a representative panel of United States households. Main outcome measures were acquisition of driver's license (a) within 12 months of the state minimum age for licensure, (b) before age 18. Associations of timing of licensure with demographic characteristics were assessed using multivariable logistic regression. Respondents not licensed before age 18 were asked to rate the importance of various possible reasons for delaying licensure. 54% of respondents were licensed before age 18. Blacks (37%; adjusted Prevalence Ratio 0.67, 95% Confidence Interval 0.48-0.93) and Hispanics (29%; adjusted Prevalence Ratio 0.60, 95% Confidence Interval 0.45-0.81) were less likely than non-Hispanic whites (67%) to be licensed before age 18. Lower household income was independently associated with delayed licensure (P < .001). The most common self-reported reasons for not becoming licensed sooner were not having a car, being able to get around without driving, and costs associated with driving. There was little evidence that GDL is a major contributor to delayed licensure; however, a substantial minority of young people do

To determine whether the ability to predict severe motor impairment at age 5 years improves between birth and 18 months. Ancillary study of the Caffeine for Apnea of Prematurity Trial. International cohort of very low birth weight children who were assessed sequentially from birth to 5 years. Severe motor impairment was defined as a score <5th percentile on the Movement Assessment Battery of Children (MABC), or inability to complete the MABC because of cerebral palsy. Multivariable logistic regression cumulative risk models used four sets of predictor variables: early neonatal risk factors, risk factors at 36 weeks' postmenstrual age, risk factors at a corrected age of 18 months, and sociodemographic variables. A receiver operating characteristic curve (ROC) was generated for each model, and the four ROC curves were compared to determine if the addition of the new set of predictors significantly increased the area under the curve (AUC). Of 1469 children, 291 (19.8%) had a severe motor impairment at 5 years. The AUC increased from 0.650 soon after birth, to 0.718 (p<0.001) at 36 weeks' postmenstrual age, and to 0.797 at 18 months (p<0.001). Sociodemographic variables did not significantly improve the AUC (AUC=0.806; p=0.07). Prediction of severe motor impairment at 5 years of age using a cumulative risk model improves significantly from birth to 18 months of age in children with birth weights between 500 g and 1250 g.

The current standard treatment for patients with high-risk neuroblastoma includes initial induction chemotherapy with a 21-day interval between induction treatments. We aimed to assess whether an intensive chemotherapy protocol that had a 10-day interval between treatments would improve event-free survival (EFS) in patients aged 1 year or over with high-risk neuroblastoma. Between Oct 30, 1990, and March 18, 1999, patients with stage 4 neuroblastoma who had not received previous chemotherapy were enrolled from 29 centres in Europe. Patients were randomly assigned to rapid treatment (cisplatin [C], vincristine [O], carboplatin [J], etoposide [E], and cyclophosphamide [C], known as COJEC) or standard treatment (vincristine [O], cisplatin [P], etoposide [E], and cyclophosphamide [C], ie, OPEC, alternated with vincristine [O], carboplatin [J], etoposide [E], and cyclophosphamide [C], ie, OJEC). Both regimens used the same total cumulative doses of each drug (except vincristine), but the dose intensity of the rapid regimen was 1.8-times higher than that of the standard regimen. The standard regimen was given every 21 days if patients showed haematological recovery, whereas the rapid regimen was given every 10 days irrespective of haematological recovery. Response to chemotherapy was assessed according to the conventional International Neuroblastoma Response Criteria (INRC). In responders, surgical excision of the primary tumour was attempted, followed by myeloablation (with 200 mg/m2 of melphalan) and haemopoietic stem-cell rescue. Primary endpoints were 3-year, 5-year, and 10-year EFS. Data were analysed by intention to treat. This trial is registered on the clinical trials site of the US National Cancer Institute website, number NCT00365755, and also as EU-20592 and CCLG-NB-1990-11. 262 patients, of median age 2.95 years (range 1.03-20.97), were randomly assigned-132 patients to standard and 130 patients to rapid treatment. 111 patients in the standard group and 109

Using text messaging, underpinned by the Health Belief Model, this study aimed to improve tooth brushing frequencies among unemployed young adults aged 18-24 years. Set within Work and Income's Linwood Community Link office (one Christchurch branch of the New Zealand Government's employment and beneficiary services), unemployed young adults aged 18-24 years with access to a mobile phone were recruited using either a purpose-built computer kiosk or Work and Income's Facebook site. Participants completed a baseline survey and then received and responded to a series of motivational text messages over 10 weeks. Self-reported tooth brushing frequency was the primary outcome variable. Important socio-demographic (age, gender, ethnicity, employment status) and method-specific (level of attrition, distribution of successful text messages deliveries, active withdrawal) variables were also collected. Longitudinal analyses of these responses employed generalized estimating equation (GEE) models. Four hundred and three registered for the trial, of whom 171 (42%) were eligible. Self-reported tooth brushing twice or more per day increased from 51% at baseline to 70% at week 3, 74% at week 6, and 73% at week 9 - an increase significant in crude (P<0.001) and adjusted (P<0.001) GEE analyses. No important differences were noted between age, gender, or ethnic groups, although attrition was relatively high with only 26% participating by week 9. However, no evidence of differential attrition was observed. Invention through motivational text messaging improved the measured oral health self-care behavior in a hard-to-reach group carrying a disproportionately heavy oral health burden.

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

To establish reference values for fatty acids (FA) especially for n-3 and n-6 long-chain polyunsaturated FAs (LC PUFA) in whole-blood samples from apparently healthy 3-8-year-old European children. The whole-blood FA composition was analysed and the age- and sex-specific distribution of FA was determined. Blood samples for FA analysis were taken from 2661 children of the IDEFICS (identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study cohort. Children with obesity (n=454) and other diseases that are known to alter the FA composition (n=450) were excluded leaving 1653 participants in the reference population. The FA composition of whole blood was analysed from blood drops by a rapid, validated gas chromatographic method. Pearson correlation coefficients showed an age-dependent increase of C18:2n-6 and a decrease of C18:1n-9 in a subsample of normal weight boys and girls. Other significant correlations with age were weak and only seen either in boys or in girls, whereas most of the FA did not show any age dependence. For age-dependent n-3 and n-6 PUFA as well as for other FA that are correlated with age (16:0, C18:0 and C18:1n-9) percentiles analysed with the general additive model for location scale and shape are presented. A higher median in boys than in girls was observed for C20:3n-6, C20:4n-6 and C22:4n-6. Given the reported associations between FA status and health-related outcome, the provision of FA reference ranges may be useful for the interpretation of the FA status of children in epidemiological and clinical studies.

Four levels of precommercial thinning were applied with and without fertilization in a young, even-aged stand of northern conifers in east-central Maine. After 18 years, precommercial thinning resulted in longer and wider crowns and greater survival, growth, and yield of selected crop trees compared to untreated controls. Growth and yield were greater with uniform...

The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged <1 year; toddlers aged 1-2 years; preschoolers aged 3-4 years). Evidence from the review was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The new guidelines include a preamble to provide context, followed by the specific recommendations. The final guidelines benefitted from extensive on-line consultations with input from >900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged <1 year), toddlers (aged 1-2 years), and preschoolers (aged 3-4 years) spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

Fractures of the clavicle are common among adolescents and have traditionally been treated nonoperatively. Recent literature has demonstrated less satisfactory results than expected after conservative management of displaced fractures in adults. The purpose of this study was to evaluate the long-term patient-reported outcome after clavicle fractures in older children and adolescents. Children aged 10 to 18 years who sustained a fracture of the clavicle between 2006 and 2008 were identified in our institution's computerized files. The radiographs were examined and the fracture patterns, degree of dislocation, and shortening were measured. Medical records were reviewed and the patient-reported outcome was assessed using the Oxford Shoulder score and the Quick version of the Disability of Arm, Shoulder, and Hand questionnaire, and specific and general satisfaction scores. A total of 185 patients (median age, 14.4 y) with 172 midshaft and 13 lateral fractures were included in the study. Sixty-five (37.8%) of the midshaft fractures were displaced, and 9 of these were operated. There was one case of nonunion and one delayed union. One hundred twenty-two (70.9%) of the patients with a midshaft fracture responded to the questionnaires on an average 4.7 years after injury. Overall results were good to excellent for the majority of nonoperatively treated patients; however, shortening of the fracture had a negative effect on the Oxford Shoulder score (P=0.02), the cosmetic satisfaction score (P=0.02), and the overall satisfaction score (P=0.01). The long-term patient-reported outcome after nonoperatively treated fractures of the clavicle in adolescents is good to excellent for the majority of the patients, and nonunion is rare. However, shortening of the fracture had a small negative effect on the outcome. Conservative management should remain the mainstay of management for fractures of the clavicle in this age group. Level IV-retrospective case series.

OBJECTIVE There have been no reports on the long-term radiographic outcomes of posterior vertebral column resection (PVCR) in patients with congenital scoliosis. The purpose of this study was to evaluate the surgical outcomes and complications after PVCR and its long-term effects on correcting this deformity in children with congenital scoliosis. METHODS The authors retrospectively analyzed the medical records of 45 patients with congenital scoliosis who were younger than 18 years at the time of surgery and who underwent PVCR and fusion with pedicle screw fixation (PSF). The mean age of the patients at the time of surgery was 11.3 years (range 2.4-18.0 years), and the mean length of follow-up was 12.8 years (range 10.1-18.2 years). RESULTS The mean Cobb angle of the main curve was 46.5° before PVCR, 13.7° immediately after PVCR, and 17.6° at the last follow-up. For the compensatory cranial curve, PVCR corrected the preoperative Cobb angle of 21.2° to 9.1° postoperatively and maintained it at 10.9° at the last follow-up. For the compensatory caudal curve, the preoperative Cobb angle of 23.8° improved to 7.7° postoperatively and was 9.8° at the last follow-up. The authors noted 22 complications, and the overall incidence of complications was 48.9%. CONCLUSIONS Posterior vertebral column resection is an effective procedure for managing congenital scoliosis in patients younger than 18 years. Use of PVCR and fusion with PSF for congenital scoliosis achieved rigid fixation and satisfactory deformity correction that was maintained over the long term. However, the authors note that PVCR is a technically demanding procedure and entails risks for major complications and excessive blood loss.

Introduction Most head circumference growth references are useful during the first years of life, but they are also useful for older children when screening for developmental, neurological, and genetic disorders. We aimed to develop head circumference growth reference charts for age, height, and waist circumference for Turkish children aged 5–18 years. Methods Head circumference, height, and waist circumference measurements were obtained from 5079 students aged 5–18 years from İzmit, Kocaeli Province, Turkey. The LMS method was used to construct reference centile curves. Results Head circumference measurements were strongly correlated with height (r=0.74), weight (r=0.76), and waist circumference (r=0.68). The mean head circumference values for boys were larger than those for girls at all ages. Compared with data from the United States, the World Health Organization, and other studies from Turkey, our data showed a decrease in head circumference at all ages for both sexes. Conclusion Local growth charts can be used to evaluate head circumference growth in older Turkish children and adolescents. PMID:28360767

Peer influence on speeding behaviour among male drivers aged 18 and 28.

PubMed

2014-03-01

Despite extensive research, preventive efforts and general improvements in road safety levels, the accident risk of young male drivers remains increased. Based on a standardized survey of a random sample of 2018 male drivers at the age of 18 and 28, this study looked into attitudes and behaviours related to traffic violations of male drivers. More specifically, the role of peer influence on speeding was examined in both age groups. In regression analyses it could be shown that the descriptive subjective norm, i.e., the perception of friends' speeding, was the most important predictor of speeding in both age groups. Other significant factors were: negative attitude towards speed limits, injunctive subjective norm, and the perceived risk of having an accident when speeding. In the older age group it was more common to drive faster than allowed and their speeding was largely in line with the perceived level of their friends' speeding. In the younger age group a higher discrepancy between own and friends' speeding was found indicating that young male drivers are socialized into increased speeding behaviour based on peer pressure. By contrast for the 28-year-olds peer pressure mainly seems to maintain or justify individual speeding behaviour. It is suggested that preventive measures should take these different influences of peer pressure into account by using a peer-based approach for the 18-year-olds and a more individual approach for the 28-year-olds.

Although adolescent girls are the main population for prophylactic human papillomavirus (HPV) vaccines, adult women who remain at risk of cervical cancer can also be vaccinated. We report data from the interim analysis of the ongoing VIVIANE study, the aim of which is to assess the efficacy, safety, and immunogenicity of the HPV 16/18 AS04-adjuvanted vaccine in adult women. In this phase 3, multinational, double-blind, randomised controlled trial, we randomly assigned healthy women older than 25 years to the HPV 16/18 vaccine or control (1:1), via an internet-based system with an algorithm process that accounted for region, age stratum, baseline HPV DNA status, HPV 16/18 serostatus, and cytology. Enrolment was age-stratified, with about 45% of participants in each of the 26-35 and 36-45 years age strata and 10% in the 46 years and older stratum. Up to 15% of women in each age stratum could have a history of HPV infection or disease. The primary endpoint was vaccine efficacy against 6-month persistent infection or cervical intraepithelial neoplasia grade 1 or higher (CIN1+) associated with HPV 16/18. The primary analysis was done in the according-to-protocol cohort for efficacy, which consists of women who received all three vaccine or control doses, had negative or low-grade cytology at baseline, and had no history of HPV disease. Secondary analyses included vaccine efficacy against non-vaccine oncogenic HPV types. Mean follow-up time was 40·3 months. This study is registered with ClinicalTrials.gov, number NCT00294047. The first participant was enrolled on Feb 16, 2006, and the last study visit for the present analysis took place on Dec 10, 2010; 5752 women were included in the total vaccinated cohort (n=2881 vaccine, n=2871 control), and 4505 in the according-to-protocol cohort for efficacy (n=2264 vaccine, n=2241 control). Vaccine efficacy against HPV 16/18-related 6-month persistent infection or CIN1+ was significant in all age groups combined (81·1%, 97·7

Age has been suggested as a negative prognostic factor for hip arthroscopy. The purpose of this study was to compare patient characteristics and outcomes after hip arthroscopy in patients aged 50 years or older with a matched control group of patients aged 30 years or younger at a minimum postoperative follow-up of 2 years. Between September 2008 and March 2010, data were prospectively collected on all patients aged 50 years or older undergoing primary hip arthroscopy. Fifty-two patients met our inclusion and matching criteria, of whom all 52 (100%) were available for follow-up at a minimum of 2 years. This cohort was compared with a matched-pair control group of patients aged 30 years or younger who underwent similar procedures. The mean age of the study group was 54.8 years (range, 50 to 69 years), and that of the control group was 20.3 years (range, 13 to 30 years). The groups were matched at a 1:1 ratio, including 18 male patients (34.6%) and 34 female patients (65.4%) in each group, with a mean follow-up period of 32 months (range, 24 to 54 months). In the younger control group, the score improvement from preoperatively to 2 years' follow-up was 62.9 to 84.2 for the modified Harris Hip Score, 60.5 to 84.2 for the Non-Arthritic Hip Score, 63.1 to 86.5 for the Hip Outcome Score-Activities of Daily Living, and 42.2 to 72.7 for the Hip Outcome Score-Sport-Specific Subscale. In the older study group, the score improvement from preoperatively to 2 years' follow-up was 61.2 to 82.2 for the modified Harris Hip Score, 59.9 to 80.4 for the Non-Arthritic Hip Score, 63.9 to 83 for the Hip Outcome Score-Activities of Daily Living, and 41.2 to 64.6 for the Hip Outcome Score-Sport-Specific Subscale. All improvements in both groups were statistically significant at the 2-year postoperative follow-up (P < .001). There was no significant difference for all patient-reported outcome (PRO) scores at final follow-up between both groups. When we compared the change in PRO scores (�

The prevalence of asthma in girls increases after puberty. Previous studies have detected associations between sex hormones and asthma, as well as between sex hormones and T helper 2 (Th2) asthma-typical immune responses. Therefore, we hypothesized that exogenous or endogenous sex hormone exposure (represented by oral contraceptive pill (OCP) use and early menarche, respectively) are associated with DNA methylation (DNA-M) of the Th2 transcription factor gene, GATA3, in turn affecting the risk of asthma in girls, possibly in interaction with genetic variants. Blood samples were collected from 245 female participants aged 18 years randomly selected for methylation analysis from the Isle of Wight birth cohort, UK. Information on use of OCPs, age at menarche, and concurrent asthma were assessed by questionnaire. Genome-wide DNA-M was determined using the Illumina Infinium HumanMethylation450 beadchip. In a first stage, we tested the interaction between sex hormone exposure and genetic variants on DNA-M of specific cytosine-phosphate-guanine (CpG) sites. In a second stage, we determined whether these CpG sites interact with genetic variants in GATA3 to explain the risk of asthma. Interactions between OCP use and seven single nucleotide polymorphisms (SNPs) of GATA3 were analyzed for 14 CpG sites (stage 1). The interaction between OCP use and SNP rs1269486 was found to be associated with the methylation level of cg17124583 (P = 0.002, false discovery rate (FDR) adjusted P = 0.04). DNA-M of this same CpG site was also influenced by the interaction between age at menarche and rs1269486 (P = 0.0017). In stage 2, we found that cg17124583 modified the association of SNP rs422628 with asthma risk at the age of 18 years (P = 0.006, FDR adjusted P = 0.04). Subjects with genotype AG showed an increase in average risk ratio (RR) from 0.31 (95% CI: 0.10 to 0.8) to 11.65 (95% CI: 1.71 to 79.5) when methylation level increased from 0.02 to 0.12, relative to

The aim of this study was to investigate associations of yogurt and dairy consumption with energy, macronutrient, calcium, and vitamin D intakes, and associations with indicators of overweight/obesity in U.S. children in the National Health and Nutrition Examination Survey (NHANES 2005–2008). Using 24-hour recall data, children 8–18 years of age were classified to dairy consumption groups of <1, 1 to <2, or 2+ dairy servings, and yogurt consumers were those who reported eating yogurt during at least one of two dietary intake interviews. NHANES anthropometric measurements were used, and BMI and BMI-for-age percentiles were calculated. Yogurt and dairy consumption were associated with higher intakes of calcium, vitamin D and protein. Yogurt intake was associated with lower total fat and saturated fat intakes and body fat as measured by subscapular skinfold thickness. This study supports consumption of yogurt and higher amounts of dairy as eating patterns associated with greater intake of specific shortfall nutrients, and lower body fat in U.S. children.

Background: Chagas disease continues to be a serious public health problem, and accounts for 25-30% of the indications for cardiac stimulation in Brazil. Objective: To assess clinical and epidemiological characteristics of patients with Chagas disease, younger than 18 years, who had undergone pacemaker implantation in Brazil between 1994 and 2011, and its temporal trend. Methods: This was a cross-sectional analysis of data from the Brazilian Pacemaker Registry database. The following variables were analyzed: year when pacemaker was implanted, location, age, sex, ethnic group, functional class and the main electrocardiographic findings at baseline. Results: In a total of 183,123 implants performed between 1994 and 2011, 214 implants of cardiac stimulation device in Chagas disease patients aged younger than 18 years were identified. Mean age at implantation was 5.6 ± 6.2 years. Second- and third-degree atrioventricular blocks corresponded to 71% of indications for pacemaker implantation. Fifty-six percent of the procedures were performed in the southeast region. Regarding the total number of pacemaker implants per year, there was a remarkable increase in the implants for all causes. However, time series analysis of the implants in Chagas disease patients younger than 18 years revealed a significant reduction in the annual number of implants. Conclusion: There has been an important reduction in the number of pacemaker implantations among children and adolescents with Chagas disease, suggesting a reduction in the vertical transmission of the parasite.

To study the development of motor speed and associated movements in participants aged 5 to 18 years for age, sex, and laterality. Ten motor tasks of the Zurich Neuromotor Assessment (repetitive and alternating movements of hands and feet, repetitive and sequential finger movements, the pegboard, static and dynamic balance, diadochokinesis) were administered to 593 right-handed participants (286 males, 307 females). A strong improvement with age was observed in motor speed from age 5 to 10, followed by a levelling-off between 12 and 18 years. Simple tasks and the pegboard matured early and complex tasks later. Simple tasks showed no associated movements beyond early childhood; in complex tasks associated movements persisted until early adulthood. The two sexes differed only marginally in speed, but markedly in associated movements. A significant laterality (p<0.001) in speed was found for all tasks except for static balance; the pegboard was most lateralized, and sequential finger movements least. Associated movements were lateralized only for a few complex tasks. We also noted a substantial interindividual variability. Motor speed and associated movements improve strongly in childhood, weakly in adolescence, and are both of developmental relevance. Because they correlate weakly, they provide complementary information.

Age of complementary foods introduction is associated with childhood anemia, but the ideal age for the introduction of complementary foods to infants is a continuing topic of debate. We examined the longitudinal association between complementary foods introduction age and risk of anemia in 18,446 children from the Jiaxing Birth Cohort, who had detailed complementary feeding records at 3 and 6 months of age and had hemoglobin concentrations measured at 4-6 years. Early introduction of complementary foods at 3-6 months of age was significantly associated with a higher risk of anemia (odds ratio = 1.14; 95% confidence interval: 1.01-1.28) and a lower hemoglobin concentration of -0.84 g/L (95% confidence interval: -1.33 to -0.35) in children aged 4-6 years, compared with those fed complementary foods starting at 6 months of age. When it comes to the specific type of complementary foods, early introduction of all plant-based foods was associated with increased anemia risks and lower hemoglobin concentrations, while early introduction of most animal-based foods was not. These findings may be informative regarding the appropriate time to introduce complementary foods in infants.

To establish BMI percentile curves that describe the contemporary BMI distribution among Chinese children, and to compare their BMI percentile curves with those in two recently developed international references: the WHO and the US Centers for Disease Control and Prevention (US CDC) growth references. A cross-sectional national survey. Thirty provinces, municipalities and autonomous regions in China. Nationally representative sample of 232 140 school students aged 7-18 years. BMI percentile curves were established using the LMS method, and were compared with the percentiles of the WHO and the US CDC references. BMI distributions and growth patterns in Chinese children were dramatically different from those in the two international reference populations. Compared with the international reference populations, younger Chinese boys (7-12 years of age) had higher values of the percentiles above the median and lower values of the percentiles below the median, suggesting that they had larger proportions of extreme BMI values in both directions. Chinese girls and older Chinese boys (15-18 years of age) had substantially lower BMI percentiles than their counterparts in the reference populations, particularly those high percentiles among older age groups. The present study described the unique patterns of BMI curves at the national level, and these curves are useful as a reference for comparing different regions and for monitoring changes over time in Chinese children. Higher proportions of children with extreme values in both directions indicate that China is currently facing both an increasing level of obesity and a high level of undernutrition, simultaneously.

To assess the factors related to the presence of polycystic ovary syndrome (PCOS) in adolescents. This was a cross-sectional study, with female adolescents from 15 to 18 years old, divided into: group 1 (with a medical diagnosis of PCOS) and group 2 (not diagnosed with PCOS). The height-for-age index and the body mass index were used for classifying the nutritional status, and a semi-structured questionnaire was applied. The Mann-Whitney test, Fisher's exact test, Spearman correlation coefficients, and logistic regression were used. This study evaluated 485 adolescents with an average age of 16.3 ± 0.9 years old. The prevalence of PCOS was 6.2%. No difference was found between the groups regarding anthropometric parameters and period of contraceptive use; however, there were differences regarding the age at menarche (p < 0.004). Older age at menarche was a protection factor against the syndrome. An association was found between younger age at menarche and the development of the PCOS in adolescents.

IMPORTANCE Age-associated changes in brain imaging and fluid biomarkers are characterized and compared in presenilin 1 (PSEN1) E280A mutation carriers and noncarriers from the world’s largest known autosomal dominant Alzheimer disease (AD) kindred. OBJECTIVE To characterize and compare age-associated changes in brain imaging and fluid biomarkers in PSEN1 E280A mutation carriers and noncarriers. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional measures of 18F-florbetapir positron emission tomography, 18F-fludeoxyglucose positron emission tomography, structural magnetic resonance imaging, cerebrospinal fluid (CSF), and plasma biomarkers of AD were assessed from 54 PSEN1 E280A kindred members (age range, 20-59 years). MAIN OUTCOMES AND MEASURES We used brain mapping algorithms to compare regional cerebral metabolic rates for glucose and gray matter volumes in cognitively unimpaired mutation carriers and noncarriers. We used regression analyses to characterize associations between age and the mean cortical to pontine 18F-florbetapir standard uptake value ratios, precuneus cerebral metabolic rates for glucose, hippocampal gray matter volume, CSF Aβ1-42, total tau and phosphorylated tau181, and plasma Aβ measurements. Age at onset of progressive biomarker changes that distinguish carriers from noncarriers was estimated using best-fitting regression models. RESULTS Compared with noncarriers, cognitively unimpaired mutation carriers had significantly lower precuneus cerebral metabolic rates for glucose, smaller hippocampal volume, lower CSF Aβ1-42, higher CSF total tau and phosphorylated tau181, and higher plasma Aβ1-42 measurements. Sequential changes in biomarkers were seen at age 20 years (95% CI, 14-24 years) for CSF Aβ1-42, age 16 years (95% CI, 11-24 years) for the mean cortical 18F-florbetapir standard uptake value ratio, age 15 years (95% CI, 10-24 years) for precuneus cerebral metabolic rate for glucose, age 15 years (95% CI, 7-20 years) for CSF total tau

Food insecurity and anemia are prevalent among low-income families and infants. Anemia may reflect iron deficiency anemia (IDA) risk. IDA in infancy and early childhood may have long-lasting developmental effects. Few studies have examined food security status (FSS) as a risk factor for anemia. To examine the association between household FSS, sociodemographic and health-related variables, and anemia incidence at age 18 months among low-income infants in the Massachusetts Special Supplemental Nutrition Program for Women, Infants, and Children (MA/WIC). This was a longitudinal study using data from MA/WIC (August 2001 to November 2009) to assess the relationship between household FSS during the 12 months preceding the 1-year visit (age 9 to 15 months) and anemia at age 18 months. Infants included were not anemic at age 12 months and had complete data on household FSS and the following covariates (N=17,831): race/Hispanic ethnicity, maternal education, breastfeeding duration, household size, and child age. Multiple logistic regression was used to examine the association between household FSS during the prior 12 months and anemia at 18 months, controlling for infant age, sex, and race/Hispanic ethnicity, breastfeeding, maternal education, and household size. A majority of infants (56%) were nonwhite, and 19.9% lived in food-insecure households (4.8% in very-low food security). Of the infants who were not anemic at age 12 months, 11.7% became anemic by age 18 months. Infants living in low-food-secure households were 42% more likely (adjusted odds ratio 1.42, 95% CI, 1.27-1.60) to develop anemia at age 18 months than were their food-secure counterparts. Nonwhite race, higher household size, and lower maternal education were also associated with an elevated risk of anemia at age 18 months. Low food security appears to be associated with a significant increased risk of anemia, as do nonwhite ethnicity, lower maternal education, and larger household size. Knowledge of

To examine the prevalence and potential determinants of rear-facing car safety seat use among children approximately 18 months of age born at a university hospital. We administered a telephone survey to caregivers of children 17-19 months of age who were born between November 2013 and May 2014. The survey was designed to assess the prevalence of rear-facing car safety seat use and estimate the likelihood of rear-facing car safety seat use, compared with forward-facing car seat use, in reference to hypothesized determinants. aORs and 95% CIs were calculated using multivariable logistic regression. In total, 56% of potentially eligible caregivers (491/877) completed the survey; 62% of these reported rear-facing car safety seat use. Race, education, rurality, and household income were associated with rear-facing car safety seat use after controlling for potential confounders. Additionally, caregivers who reported having discussed car seats with their child's provider (aOR 1.7; 95% CI 1.1-2.6); receiving their child's primary care in pediatrics compared with family practice clinics (aOR 2.4; 95% CI 1.1-2.6); and being aware of the American Academy of Pediatrics rear-facing recommendation (aOR 2.8; 95% CI 1.8-4.1) were significantly more likely to report rear-facing car safety seat use. Conversely, caregivers who previously used a car seat with another child were less likely to have their child rear facing at 18 months of age (aOR 0.6; 95% CI  0.4-0.9). A large proportion of children were forward facing at 18 months of age. Future efforts focused on encouraging providers to discuss car seats during patient visits, increasing awareness of the American Academy of Pediatrics' rear-facing recommendation, and targeting high-risk populations may improve the prevalence of children who remain rear facing until 2 years of age.

Zelaya, Carla E; Lucas, Jacqueline W; Hoffman, Howard J

2015-09-01

Age is typically the most significant determinant of hearing loss (5,6). Among U.S. adults in 2014, self-reported hearing loss was most prevalent among adults aged 70 and over (43.2%), compared with adults aged 40-69 (19.0%) and aged 18-39 (5.5%). Age-related hearing loss is often overlooked due to its deceptively slow progression, lack of attention from providers, and public acceptance as a condition that is perceived to be a "normal" consequence of aging (7). Among U.S. adults aged 70 and over who had any trouble hearing, 56.8% had seen a doctor or other health care professional about their hearing or ear problems in the past 5 years, but only 42.0% had ever used a hearing aid. Younger adults (aged 18-39) who had any trouble hearing were even less likely to have seen a doctor or used a hearing aid, but they were more likely to have used other assistive technology because of their hearing compared with adults aged 40-69 or 70 and over. Among U.S. adults who had any trouble hearing without a hearing aid, 1.7% were deaf, but the majority (62.6%) had mild hearing loss (defined as "a little trouble hearing"). Men were more likely than women to have self-reported trouble hearing, a sex disparity that has been documented globally among all age groups (8). Men were also more likely than women to state they had moderate trouble hearing.

Empirical research about late sexual debut and its consequences is limited, and further research is needed. To explore how students who had not had intercourse by the age of 18 years differed in terms of sociodemographic factors, physical and psychological health, sexual behavior, and history of sexual abuse from those who had. This is a cross-sectional survey involving 3,380 Swedish 18-year-olds. Descriptive analyses were used to investigate different types of sexual behavior. Ordinal data concerning alcohol consumption, self-esteem, sexual and physical abuse, parental relationships, sense of coherence, and health were analyzed, and multiple regression was carried out to identify the most important factors associated with no sexual debut. Just under a quarter of the adolescents had not had oral, anal, or vaginal sex by the age of 18 years, and they comprised the index group. They were characterized by being more likely to have caring fathers, parents born outside Europe, lower pornography consumption, lower alcohol and tobacco consumption, less antisocial behavior, and above all lower sexual desire (sometimes, adjusted odds ratio [aOR] 3.8; never/seldom, aOR 13.3) and fewer experiences of sexual abuse (aOR 25.5). Family structure and culture matters when it comes to the age of sexual debut. Adolescents with no sexual debut at 18 years of age seemed to live a more stable and cautious life than more sexual experienced peers, exemplified by fewer antisocial acts, less smoking and alcohol/drug consumption, less sexual desire, and less experience of sexual abuse.

The 1979 Massachusetts law raising the legal drinking age from 18 to 20 is examined--the effects on the drinking, drinking and driving, and nonfatal and fatal crash involvement of 16-17 yr-olds, teenagers immediately younger than those targeted by the law. Data from Massachusetts are compared with those from New York State, where the drinking age remained at 18. A total of 3 yr of survey data from the two states and 6 yr of data from the Department of Transportation's Fatal Accident Reporting System provide for pre- and postlaw comparisons. The findings suggest that raising the drinking age had minimal effects on the drinking behavior of Massachusetts teenagers. Although there was a significant reduction in nonfatal crashes in Massachusetts compared with New York, no decline in single-vehicle nighttime fatal crashes or in overall fatal crashes was observed. It is suggested that changes in the drinking age may offer some reduction in teenage driving after drinking and traffic crash involvement, but that teenage drinking and driving after drinking remain serious problems even in states that raise their drinking ages.

Change in Body Weight from Age 20 Years Is a Powerful Determinant of the Metabolic Syndrome.

Higher body weight is a well-known determinant of the metabolic syndrome (MetS) and its components. It is however less well studied how the change in weight from age 20 years to middle age or old age affects MetS development. In the community-based EpiHealth (n = 19,000, age range 45 to 75 years, 56% females) and PIVUS (n = 1000, all aged 70 years, 50% females) studies, the participants were asked about their body weight at age 20 years. Data were collected to determine MetS prevalence (NCEP ATP III criteria). In EpiHealth, the probability of having MetS increased fairly linearly with increasing weight from age 20 in the obese [odds ratios (OR) 1.04 per kg change in weight, 95% confidence interval (CI) 1.03-1.05, P < 0.0001], as well as in the overweight (OR 1.15, 95% CI 1.14-1.17, P < 0.0001) and normal-weight (OR 1.18, 95% CI 1.14-1.21, P < 0.0001), subjects after adjustment for age, sex, body mass index (BMI) at age 20, alcohol intake, smoking, education, and exercise habits. Also in the PIVUS study, the change in weight over 50 years was related to prevalent MetS (OR 1.08 per kg change in weight, 95% CI 1.06-1.10, P < 0.0001). In both studies, self-reported BMI at age 20 was related to prevalent MetS. Self-reported weight gain from age 20 was strongly and independently associated with prevalent MetS both in middle age or old age. Interestingly, this relationship was not restricted only to obese subjects. Our data provide additional support for the importance of maintaining a stable weight throughout life.

An 18-year-old man with recurrent pneumothorax since he was 10-year-old.

An 18-year-old male patient was referred to the department of pediatric pulmonology with a history of recurrent pneumothorax. Initial pneumothorax occurred at the age of 10. Following diagnosis of congenital lobar emphysema, he had five episodes of pneumothorax and subsequently underwent right-lower lobe anterobasal segmentectomy. Based on thoracic computed tomography (CT) and clinical manifestation, Birt-Hogg-Dube (BHD) syndrome was suspected and confirmed following genetic testing. BHD syndrome is a rare tumor predisposition syndrome first described in 1977. The syndrome is characterized by skin fibrofolliculomas, lung cysts, recurrent spontaneous pneumothorax, and renal cell cancer. The underlying cause is a germline mutation in the folliculin (FLCN) gene located on chromosome 17p11.2. Clinical manifestation usually appears after the age of 20 years. In this case, we report a case of BHD with episodes of recurrent pneumothorax, the first of which occurred at the age of 10 years. Pulmonologists should be aware of this syndrome in patients with a personal and family history of pneumothoraces and CT findings of multiple pulmonary cysts as additional evaluation and testing may be warranted.

Genetic moderation of stability in attachment security from early childhood to age 18 years: A replication study.

PubMed

Raby, K Lee; Roisman, Glenn I; Booth-LaForce, Cathryn

2015-11-01

A longstanding question for attachment theory and research is whether genetically based characteristics of the child influence the development of attachment security and its stability over time. This study attempted to replicate and extend recent findings indicating that the developmental stability of attachment security is moderated by oxytocin receptor (OXTR) genetic variants. Using longitudinal data from over 550 individuals, there was no evidence that OXTR rs53576 moderated the association between attachment security during early childhood and overall coherence of mind ("security") during the Adult Attachment Interview at age 18 years. Additional analyses involving a second commonly investigated OXTR variant (rs2254298) and indices of individuals' dismissing and preoccupied attachment states of mind also failed to provide robust evidence for oxytonergic moderation of the stability in attachment security across development. The discussion focuses on research strategies for investigating genetic contributions to attachment security across the life span. (c) 2015 APA, all rights reserved).

Objective: To study the effect of family integrated care (FIC) in neonatal intensive care unit (NICU) to the development of preterm infants at 18 months of age. Method: This is a prospective parallel case-control study. Infants in FIC group were preterm infants enrolled in previous FIC study with gestational age (GA) 28-35 weeks. Study period was from July 2015 to July 2016. Subjects were all enrolled from Department of Child Healthcare in the Third Xiangya Hospital of Central South University. Infants in control group were gender, birth weight (BW), BW percentile and days of life (DOL) at follow-up matched (1∶1 ratio) preterm infants who did not enter FIC in NICU. The age at follow-up was 18 months. Study parameters were maternal education year, socioeconomic status (SES) by Graffar method, home observation for measurement of the environment (HOME), mental development index (MDI) and psychomotor development index (PDI) by mental and psychomotor Bayley scales of infant development (BSID). SPSS 20.0 of χ 2 test, t test, Pearson coefficient test and Spearman coefficient test were used for the statistical analysis. Result: Totally 67 infants were enrolled in each of FIC group and control group, with percentage of male gender 52% (35 infants) and 51% (34 infants), representatively. GA of FIC group and control group was (32.4±1.7) and (32.2±1.6) weeks, BW was (1 690±415) and (1 719±412) g. Weight at 18 months follow-up was (10±1) and (10±1) kg, maternal education year was (15±2) and (15±2) years, SES was (42±6) and (41±6) score, HOME was (31±5) and (32±5) score, representatively. There was no significant difference between FIC group and control group in the above parameters, making these 2 groups comparable. The MDI and PDI of FIC group were significantly higher than those of control group ((95±9) vs . (86±9), (87±9) vs . (80±8) score, t =5.506, 4.502, both P =0.000).

study, 246 were white (88%), 260 were non-Hispanic (93%), 210 were married (75%), and 201 were working full time (72%) at time of enrollment. The mean conditional weight gain score was lower among infants in the RP group compared with the control group (−0.18; 95% CI, −0.36 to −0.001), reflecting that the RP infants gained weight more slowly than control group infants (0.18; 95% CI, 0.02–0.34); this effect did not differ by feeding mode (predominantly fed breast milk or not). Infants in the RP group also had lower mean weight-for-length percentiles at 1 year than infants in the control group (57.5%; 95% CI, 52.56%–62.37% vs 64.4%; 95% CI, 59.94%–69.26%; P = .04) and were less likely to be overweight at age 1 year (5.5% vs 12.7%; P = .05). CONCLUSIONS AND RELEVANCE An RP intervention is associated with reduced rapid weight gain during the first 6 months after birth and overweight status at age 1 year.

The life expectancy of persons with Prader-Willi syndrome (PWS) has increased in recent years. Because of the paucity of reports on older persons with PWS, the natural history, the onset, and type of age-related problems are poorly understood. Twelve persons with a genetically confirmed diagnosis of PWS aged over 50 years are described (4 deletion; 8 mUPD). Data on physical, behavioral, psychiatric, and aging characteristics were collected through semi-structured interviews with the individuals with PWS and their main carers. Cardiovascular diseases, diabetes, dermatological, and orthopedic problems were common physical complaints in older people with PWS. Functioning in activities of daily living, psychological functioning, physical functions, and care dependence were substantially worse in the older age group (50+) compared to the control group (18-49 years). Seven out of eight persons with mUPD had a history of psychiatric illness. Behavioral problems were observed in the older age group. Given the combination of age-related physical morbidity, physical appearance, behavioral and psychiatric problems, and functional decline in our cohort, we hypothesize that premature aging occurs in PWS. The care for older people with PWS requires a lifespan approach that recognizes the presence, progression, and consequences of specific morbidity. Special medical surveillance of people with PWS from 40 years onwards would ensure that intervention and support is offered with respect to specific areas of decline at the earliest possible time.

To determine a range of anthropometric measurements including skinfold thickness measurements in four different areas of the body, to construct population growth charts for body mass index (BMI), skinfolds, and to compare these with growth charts from other countries. One aim was also to validate body fat charts derived from skinfold thickness. A national cross-sectional growth survey of children, 0-18 years old, was conducted using multistage stratified random sampling. The sample size included at least 200 children in each age-sex group. Height, weight, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, and mid-upper-arm circumference were measured in each child. We describe correlation, standard deviation scores relative to the other standards, and calculation of body density in the United Arab Emirates population. We determined whether any of the above is a good indicator of fatness in children. BMI, upper-arm circumference, sum of four skinfolds, and percentage body fat charts were constructed using the LMS method of smoothing. BMI was very significantly correlated with sum of skinfold thicknesses, and mid-upper-arm circumference. Prevalence of obesity and overweight in ages 13-17 years was respectively 9.94% and 15.16% in females and 6.08% and 14.16% in males. Derived body fat charts were found not to be accurate. A national BMI, upper-arm circumference, and sum of four skinfolds chart has been constructed that can be used as a reference standard for the United Arab Emirates. Sum of four skinfold thickness charts can be used as crude determinants of adiposity in children, but derived body fat charts were shown to be inaccurate.

To investigate factors associated with sleep duration in adolescence. Data are from the 1993 Pelotas Birth Cohort Study of 5249 live births. Of these individuals, 4563 were located for follow-up at 18 years of age, and 4106 agreed to be interviewed (follow-up rate 81.3%). Sleep duration was continuously assessed by survey as hours per weekday. Additional covariates were collected during the perinatal period and at the 11- and 18-year follow-ups. Linear regression models were used to estimate associations between sleep duration and its hypothesized influences. All analyses were sex-stratified. The average sleep duration among participants was 8.4 hours (standard deviation 1.9). Longer sleep duration at 18 years of age was associated with the following perinatal factors: low maternal schooling, low family income, maternal black skin color, and low birth weight; and with the following factors measured at 18 years of age: being out of school, low achieved schooling, low family income, absence of depressive symptoms, and high screen time. Social and demographic variables may play an important role in determining adolescents' sleep duration, but the nature of these relationships in Brazil may differ from those observed in higher-income contexts.

In young children, iron deficiency (ID)-the most common cause of anemia-may adversely affect long-term neurodevelopment and behavior. We prospectively evaluated the prevalence of ID and iron deficiency anemia (IDA) in 256 healthy 18- to 36-month-old children in Northern Israel. Complete blood count and ferritin evaluation were performed, and risk factors were assessed. Hemoglobin (Hgb) was compared with first-year routine screening. Complete data were obtained from 208 children: 56.2% were boys; the mean age was 26.1±5.27 months. A prevalence of 5.8% IDA, 16.3% ID without anemia, 9.6% anemia with normal ferritin, and 68.3% normal Hgb and ferritin was found. In nonanemic infants at 1 year of age (n=156), ID/IDA was found in 19.9%, and 12.8% became anemic at study evaluation. Despite iron supplementation in the first year, and normal Hgb at first-year screening, ID and IDA were still prevalent, and might develop during the second year of life. Recognition of this child subset and consideration of iron supplementation are mandatory.

In 2015, an estimated 18.4 million U.S. adults had current asthma, and 3,396 adult asthma deaths were reported (1). An estimated 11%-21% of asthma deaths might be attributable to occupational exposures (2). To describe asthma mortality among persons aged 15-64 years,* CDC analyzed multiple cause-of-death data † for 1999-2016 and industry and occupation information collected from 26 states § for the years 1999, 2003, 2004, and 2007-2012. Proportionate mortality ratios (PMRs) ¶ for asthma among persons aged 15-64 years were calculated. During 1999-2016, a total of 14,296 (42.9%) asthma deaths occurred among males and 19,011 (57.1%) occurred among females. Based on an estimate that 11%-21% of asthma deaths might be related to occupational exposures, during this 18-year period, 1,573-3,002 asthma deaths in males and 2,091-3,992 deaths in females might have resulted from occupational exposures. Some of these deaths might have been averted by instituting measures to prevent potential workplace exposures. The annual age-adjusted asthma death rate** per 1 million persons aged 15-64 years declined from 13.59 in 1999 to 9.34 in 2016 (p<0.001) among females, and from 9.14 (1999) to 7.78 (2016) (p<0.05) among males. The highest significantly elevated asthma PMRs for males were for those in the food, beverage, and tobacco products manufacturing industry (1.82) and for females were for those in the social assistance industry (1.35) and those in community and social services occupations (1.46). Elevated asthma mortality among workers in certain industries and occupations underscores the importance of optimal asthma management and identification and prevention of potential workplace exposures.

Early malnutrition is linked to poor cognition, but long-term effects have not been extensively examined and psychosocial confounds have not always been controlled. To test the hypothesis that malnutrition at age 3 years will be associated with poorer cognitive ability at age 11 years independent of psychosocial confounds. A prospective, longitudinal study of a birth cohort of 1559 children originally assessed at age 3 years for malnutrition (low hemoglobin level, angular stomatitis, kwashiorkor, and sparse, thin hair) and followed up to age 11 years. A community sample of 1559 children (51.4% boys and 48.6% girls) born between September 1, 1969, and August 31, 1970, in 2 towns in the island of Mauritius, with 68.7% Indians and 25.7% Creoles (African origin). Verbal and spatial ability measured at ages 3 and 11 years and reading, scholastic ability, and neuropsychologic performance measured at age 11 years. Malnourished children had poorer cognition at both ages. Deficits were stable across time, applied to all sex and ethnic groups, and remained after controlling for multiple measures of psychosocial adversity. Children with 3 indicators of malnutrition had a 15.3-point deficit in IQ at age 11 years. Malnutrition at age 3 years is associated with poor cognition at age 11 years independent of psychosocial adversity. Promoting early childhood nutrition could enhance long-term cognitive development and school performance, especially in children with multiple nutritional deficits.

The associations of parity and maternal age with small-for-gestational-age, preterm, and neonatal and infant mortality: a meta-analysis

PubMed Central

2013-01-01

Background Previous studies have reported on adverse neonatal outcomes associated with parity and maternal age. Many of these studies have relied on cross-sectional data, from which drawing causal inference is complex. We explore the associations between parity/maternal age and adverse neonatal outcomes using data from cohort studies conducted in low- and middle-income countries (LMIC). Methods Data from 14 cohort studies were included. Parity (nulliparous, parity 1-2, parity ≥3) and maternal age (<18 years, 18-<35 years, ≥35 years) categories were matched with each other to create exposure categories, with those who are parity 1-2 and age 18-<35 years as the reference. Outcomes included small-for-gestational-age (SGA), preterm, neonatal and infant mortality. Adjusted odds ratios (aOR) were calculated per study and meta-analyzed. Results Nulliparous, age <18 year women, compared with women who were parity 1-2 and age 18-<35 years had the highest odds of SGA (pooled adjusted OR: 1.80), preterm (pooled aOR: 1.52), neonatal mortality (pooled aOR: 2.07), and infant mortality (pooled aOR: 1.49). Increased odds were also noted for SGA and neonatal mortality for nulliparous/age 18-<35 years, preterm, neonatal, and infant mortality for parity ≥3/age 18-<35 years, and preterm and neonatal mortality for parity ≥3/≥35 years. Conclusions Nulliparous women <18 years of age have the highest odds of adverse neonatal outcomes. Family planning has traditionally been the least successful in addressing young age as a risk factor; a renewed focus must be placed on finding effective interventions that delay age at first birth. Higher odds of adverse outcomes are also seen among parity ≥3 / age ≥35 mothers, suggesting that reproductive health interventions need to address the entirety of a woman’s reproductive period.

To estimate (1) productive life years (PLYs) lost because of chronic conditions in Australians aged 45-64 years from 2010 to 2030, and (2) the impact of this loss on gross domestic product (GDP) over the same period. A microsimulation model, Health&WealthMOD2030, was used to project lost PLYs caused by chronic conditions from 2010 to 2030. The base population consisted of respondents aged 45-64 years to the Australian Bureau of Statistics Survey of Disability, Ageing and Carers 2003 and 2009. The national impact of lost PLYs was assessed with Treasury's GDP equation. Lost PLYs due to chronic disease at 2010, 2015, 2020, 2025 and 2030 (ie, whole life years lost because of chronic disease); the national impact of lost PLYs at the same time points (GDP loss caused by PLYs); the effects of population growth, labour force trends and chronic disease trends on lost PLYs and GDP at each time point. Using Health&WealthMOD2030, we estimated a loss of 347,000 PLYs in 2010; this was projected to increase to 459,000 in 2030 (32.28% increase over 20 years). The leading chronic conditions associated with premature exits from the labour force were back problems, arthritis and mental and behavioural problems. The percentage increase in the number of PLYs lost by those aged 45-64 years was greater than that of population growth for this age group (32.28% v 27.80%). The strongest driver of the increase in lost PLYs was population growth (accounting for 89.18% of the increase), followed by chronic condition trends (8.28%). Our study estimates an increase of 112 000 lost PLYs caused by chronic illness in older workers in Australia between 2010 and 2030, with the most rapid growth projected to occur in men aged 55-59 years and in women aged 60-64 years. The national impact of this lost labour force participation on GDP was estimated to be $37.79 billion in 2010, increasing to $63.73 billion in 2030.

We used growth and diet data from a fishery-independent survey of Chinook salmon Oncorhynchus tshawytscha, acoustic estimates of prey density and biomass, and statistical catch-at-age modeling to study the influence of the year-class strength of alewife Alosa pseudoharengus on the prey selection and abundance of age-1 Chinook salmon in Lake Michigan during the years 1992-1996 and 2001-2005. Alewives age 2 or younger were a large part of age-1 Chinook salmon diets but were not selectively fed upon by age-1 Chinook salmon in most years. Feeding by age-1 Chinook salmon on alewives age 2 or younger became selective as the biomass of alewives in that young age bracket increased, and age-1 Chinook salmon also fed selectively on young bloaters Coregonus hoyi when bloater density was high. Selection of older alewives decreased at high densities of alewives age 2 or younger and, in some cases, high densities of bloater. The weight and condition of age-1 Chinook salmon were not related to age-1 Chinook salmon abundance or prey abundance, but the abundance of age-1 Chinook salmon in year t was positively related to the density of age-0 alewives in year t - 1. Our results suggest that alewife year-class strength exerts a positive bottom-up influence on age-1 Chinook salmon abundance, prey switching behavior by young Chinook salmon contributing to the stability of the predator-prey relationship between Chinook salmon and alewives. ??

Mold exposures may contribute to the development of asthma, but previous studies have lacked a standardized approach to quantifying exposures. To determine whether mold exposures at the ages of 1 and/or 7 years were associated with asthma at the age of 7 years. This study followed up a high-risk birth cohort from infancy to 7 years of age. Mold was assessed by a DNA-based analysis for the 36 molds that make up the Environmental Relative Moldiness Index (ERMI) at the ages of 1 and 7 years. At the age of 7 years, children were evaluated for allergic sensitization and asthma based on symptom history, spirometry, exhaled nitric oxide, and airway reversibility. A questionnaire was administered to the parent regarding the child's asthma symptoms and other potential cofactors. At the age of 7 years, 31 of 176 children (18%) were found to be asthmatic. Children living in a high ERMI value (≥5.2) home at 1 year of age had more than twice the risk of developing asthma than those in low ERMI value homes (<5.2) (adjusted odds ratio [aOR], 2.6; 95% confidence interval [CI], 1.10-6.26). Of the other covariates, only parental asthma (aOR, 4.0; 95% CI, 1.69-9.62) and allergic sensitization to house dust mite (aOR, 4.1; 95% CI, 1.55-11.07) were risk factors for asthma development. In contrast, air-conditioning at home reduced the risk of asthma development (aOR, 0.3; 95% CI, 0.14-0.83). A high ERMI value at 7 years of age was not associated with asthma at 7 years of age. Early exposure to molds as measured by ERMI at 1 year of age, but not 7 years of age, significantly increased the risk for asthma at 7 years of age.

This paper reports the toxicity of OPEC/OJEC chemotherapy in stage 4 neuroblastoma patients over 1 year of age. Ninety-five patients with stage 4 neuroblastoma received alternating courses of OPEC/OJEC--vincristine 1.5 mg/m2 (O), cisplatin 80 mg/m2 (P), etoposide 200 mg/m2 (E), cyclophosphamide 600 mg/m2 (C), and carboplatin 500 mg/m2 (J), every 21 days if there was haematological recovery. Seventy out of ninety-five (74%) patients completed seven or more courses and were evaluable for toxicity. Of these 70 patients, 33% had more than three episodes of fever and sepsis, 35% required more than five blood or platelet transfusions, 36% had grade 2 or more gastrointestinal toxicity and 9% had neurotoxicity. There was a median reduction in GFR of 32 ml/min/1.73 m2 (-46 to 134) and there was one toxic death. OPEC/OJEC is a well-tolerated therapy for stage 4 neuroblastoma over 1 year of age.

Studies of aging usually focus on trajectories of physical and cognitive function, with far less emphasis on overall mental health, despite its impact on general health and mortality. This study examined linear and nonlinear trends of physical, cognitive, and mental health over the entire adult lifespan. Cross-sectional data were obtained from 1,546 individuals aged 21-100 years, selected using random digit dialing for the Successful AGing Evaluation (SAGE) study, a structured multicohort investigation that included telephone interviews and in-home surveys of community-based adults without dementia. Data were collected from 1/26/2010 to 10/07/2011 targeting participants aged 50-100 years and from 6/25/2012 to 7/15/2013 targeting participants aged 21-100 years with an emphasis on adding younger individuals. Data included self-report measures of physical health, measures of both positive and negative attributes of mental health, and a phone interview-based measure of cognition. Comparison of age cohorts using polynomial regression suggested a possible accelerated deterioration in physical and cognitive functioning, averaging 1.5 to 2 standard deviations over the adult lifespan. In contrast, there appeared to be a linear improvement of about 1 standard deviation in various attributes of mental health over the same life period. These cross-sectional findings suggest the possibility of a linear improvement in mental health beginning in young adulthood rather than a U-shaped curve reported in some prior studies. Lifespan research combining psychosocial and biological markers may improve our understanding of resilience to mental disability in older age and lead to broad-based interventions promoting mental health in all age groups. © Copyright 2016 Physicians Postgraduate Press, Inc.

The obesity and hypertension are the major risk factors of several life threatening diseases. The present study was aimed to investigate the relation between body mass index (BMI) the validated index of adiposity and different aspect of blood pressure (BP). Systolic and diastolic blood pressures and also weight and height of 7 to 18 years old children and adolescent collected in 2002 and 2004 respectively. Data was consisted of 14865 schoolchildren and adolescents from representative sample of country. BMI was classified according to CDC 2000 standards into normal (BMI<85th percentile), at risk of overweight (BMI≥85th and <95th percentile) and overweight (BMI≥95th percentile). Then, age-sex specific prevalence of being overweight was derived. ANOVA was used to investigate the effect of BMI on systolic blood pressure and diastolic blood pressure and mean arterial pressure of participants. Mean systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial blood pressure (MAP) significantly increased with BMI (P< 0.0001) and age groups (P< 0.0001), and was significantly (P< 0.0001) higher in boys than girls especially in older ages. (P< 0.0001, interaction of age and BMI level). The proportion of being overweight was significantly higher in boys than girls was (7.4% vs. 3.6%; P< 0.0001). There is an association between BP and BMI in children and adolescence. SBP, DBP and MAP are associated with rise in BMI and age, which was lower in girls. This data can provide basics for public health policy makers and primary prevention policies in the country.

Since Plasmodium falciparum transmission relies exclusively on sexual-stage parasites, several malaria control strategies aim to disrupt this step of the life cycle. Thus, a better understanding of which individuals constitute the primary gametocyte reservoir within an endemic population, and the temporal dynamics of gametocyte carriage, especially in seasonal transmission settings, will not only support the effective implementation of current transmission control programmes, but also inform the design of more targeted strategies. A 1-year prospective cohort study was initiated in June 2013 with the goal of assessing the longitudinal dynamics of P. falciparum gametocyte carriage in a village in Mali with intense seasonal malaria transmission. A cohort of 500 individuals aged 1-65 years was recruited for this study. Gametocyte prevalence was measured monthly using Pfs25-specific RT-PCR, and analysed for the effects of host age and gender, seasonality, and multiclonality of P. falciparum infection over 1 year. Most P. falciparum infections (51-89%) in this population were accompanied by gametocytaemia throughout the 1-year period. Gametocyte prevalence among P. falciparum-positive individuals (proportion of gametocyte positive infections) was associated with age (p = 0.003) but not with seasonality (wet vs. dry) or gender. The proportion of gametocyte positive infections were similarly high in children aged 1-17 years (74-82% on median among 5 age groups), while older individuals had relatively lower proportion, and those aged > 35 years (median of 43%) had significantly lower than those aged 1-17 years (p < 0.05). Plasmodium falciparum-positive individuals with gametocytaemia were found to have significantly higher P. falciparum multiclonality than those without gametocytaemia (p < 0.033 in two different analyses). Taken together, these results suggest that a substantial proportion of Pf-positive individuals carries gametocytes throughout the year, and

The pediatric perforated appendix rate is a quality metric measured by the Agency for Healthcare Research and Quality (AHRQ) that reflects access to care. The association of health care utilization prior to presentation with appendicitis is unknown. To determine whether increased health care utilization prior to presentation with appendicitis is associated with lower perforated appendicitis rates in children. Retrospective cohort study of privately insured children drawn from large employer and insurance company administrative data found in the Truven MarketScan national insurance claims database. Cases of appendicitis were identified among 38 348 children 18 years or younger from January 1, 2010, through December 31, 2013, with corresponding primary health care encounters from January 1, 2009, through December 31, 2012. In all, 19 109 eligible children were identified using International Classification of Diseases, Ninth Revision (ICD-9) diagnosis codes for appendicitis after excluding those patients who did not have continuous insurance coverage during the study period. Statistical analysis was performed from September 1, 2016, to October 15, 2017. Health care utilization was determined by the number of outpatient clinic encounters for each patient in the 1 to 12 months before presentation with appendicitis. Perforated appendicitis was defined according to the AHRQ by using ICD-9 codes for perforation and hospital length of stay of 3 or more days. Logistic regression models were used for perforated appendicitis after adjustment for age, sex, income, gastrointestinal comorbidities, geographic region, and insurance type. We identified 38 348 children 18 years or younger with ICD-9 diagnosis codes for appendicitis, and 19 109 children remained for analysis after applying exclusion criteria. Of these, 11 422 were boys (59.8%); the mean (SD) age was 12.4 (3.9) years. Of the 19 109 children identified who underwent appendectomy, 5509 (28.8%) presented with

Estimation of aggregate exposure and risk requires detailed information regarding dermal contact and mouthing activity. We analyzed micro-level activity time series (MLATS) of children aged 7-12 years to quantify these contact behaviors and evaluate differences by age and gender. In all, 18 children, aged 7-12 years, were videotaped while playing outdoors. Video footage was transcribed via Virtual Timing Device (VTD) software. We calculated the hand and mouth contact frequency, hourly duration and median duration of contact with 16 object categories. Median mouthing frequencies were 12.6 events/h and 2.6 events/h for hands and non-dietary objects, respectively. Median hourly mouthing duration was 0.4 min/h and 0.1 min/h with hands and objects. Median mouthing contact duration was 1 s and 1.5 s with hands and objects, respectively. The median object contact frequency for both the hands combined was 537.3 events/h with an hourly contact duration of 81.8 min/h and a median contact duration of 3 s. There were no significant differences in the mouthing activity between genders or age groups. Female children had longer and more frequent hand contacts with several surface types. Age was negatively correlated with hand contacts of floor and wood surfaces. Contact frequencies in this study are higher than current regulatory recommendations for this age group.

Upper and lower respiratory infections are common in early childhood and may be exacerbated by air pollution. We investigated short-term changes in ambient air pollutant concentrations, including speciated particulate matter less than 2.5 μm in diameter (PM2.5), in relation to emergency department (ED) visits for respiratory infections in young children. Daily counts of ED visits for bronchitis and bronchiolitis (n = 80,399), pneumonia (n = 63,359), and upper respiratory infection (URI) (n = 359,246) among children 0-4 years of age were collected from hospitals in the Atlanta, Georgia, area for the period 1993-2010. Daily pollutant measurements were combined across monitoring stations using population weighting. In Poisson generalized linear models, 3-day moving average concentrations of ozone, nitrogen dioxide, and the organic carbon fraction of particulate matter less than 2.5 μm in diameter (PM2.5) were associated with ED visits for pneumonia and URI. Ozone associations were strongest and were observed at low (cold-season) concentrations; a 1-interquartile range increase predicted a 4% increase (95% confidence interval: 2%, 6%) in visits for URI and an 8% increase (95% confidence interval: 4%, 13%) in visits for pneumonia. Rate ratios tended to be higher in the 1- to 4-year age group compared with infants. Results suggest that primary traffic pollutants, ozone, and the organic carbon fraction of PM2.5 exacerbate upper and lower respiratory infections in early life, and that the carbon fraction of PM2.5 is a particularly harmful component of the ambient particulate matter mixture. © The Author 2014.

College students have been the focus of many studies on suicidal ideation with or without suicidal behavior. Little attention has been given to their non-college-attending peers on these issues. We examined the 12-month prevalence and mental health treatment of suicidal ideation with or without suicidal behavior among college students aged 18-25 years and their non-college-attending peers in the United States. We assessed data from 135,300 persons aged 18-25 years who participated in the 2008-2013 National Surveys on Drug Use and Health. Descriptive analyses and multivariate logistic regression models were applied. Compared with full-time college students, high school students, those not enrolled in a school or college, and part-time college students were more likely to attempt suicide with a plan (model-adjusted prevalence = 0.67% vs 1.09%, 1.06%, and 1.07%, respectively). The mental health treatment rate among full-time college students with suicidal ideation with or without suicidal behavior was similar to the rates among the other 3 counterparts. The effects of race/ethnicity and serious mental illness on receipt of mental health treatment were significantly larger among those who did not perceive unmet treatment need than among those who perceived unmet treatment need (P = .019 and P = .001, respectively). Compared to full-time college students, non-college-attending young adults and part-time college students were at higher risk for attempting suicide with a plan. Suicide prevention and intervention strategies should emphasize increasing access to mental health treatment among both college students with suicidal ideation with or without suicidal behavior and their non-college-attending peers (particularly among minorities and those who seem to be at low risk because they are without serious mental illness and report no need for mental health treatment). © Copyright 2016 Physicians Postgraduate Press, Inc.

Epidemiological studies performed during last decades in many European countries and in the world proved increasing incidence rate of diabetes, especially diabetes type 1 in children (DMT1). In Europe there is one of the highest diabetes incidence rate. The aim of the study was to estimate the incidence rate of diabetes type 1 in children aged 0-14 years in North-East Poland during 2005-2012 years and to analyse this rates in relation to age, gender and season of the diabetes onset. The study was performed among patients staying under care of outpatient diabetes clinic of the Department of Pediatric, Endocrinologym Diabetology with Cardilogy Division, medical University of Białystok, Poland. The DMT1 incidence rate was calculated as the number of all newly diagnosed cases per 100 000 persons 0-14 aged matched. During the studied 8-years- period DMT1 was diagnosed in 306 children aged 0-14 years, 159 boys and 147 girls, in Podlasie Province. The highest number of new cases was found in 2011: 49, and 2012: 47, with the lowest number in 2005 and 2009: 32 each year. The average incidence rate in the studied period was 20,84/100 000 population, aged matched. The lowest incidence rate was found in 0-4 yrs old group: 14,59 /100 000, in 5-9 years old group was: 22,04/100 000, and was highest in 10-14 years old group: 24,94/100 000. The highest increase in incidence rate was noted in the youngest group: from 9,14/100 000 in 2005, to 23,45/100 000 in 2012. The greatest number of new recognisions was found in from November to March, and the lowest number from June to August. 1. The DMT1 incidence rate among children aged 0-14 years, in Podlasie Province, during 2005-2012 years was 20,84/100 000. 2. Increase in incidence rate was observed in the studied period from 15,23/100 000 in 2005 to 26,71/100 000 in 2012. The highest increase in incidence rate, 2,5 times, was fund in the youngest group, aged 0-4 years. 3. The seasonal incidence of New onset was observed with the

Objective Decrements in cognitive function may already be evident in young children with type 1 diabetes (T1D). Here we report prospectively acquired cognitive results over 18 months in a large cohort of young children with and without T1D. Methods 144 children with T1D (mean HbA1c: 7.9%) and 70 age-matched healthy controls (mean age both groups 8.5 years; median diabetes duration 3.9 yrs; mean age of onset 4.1 yrs) underwent neuropsychological testing at baseline and after 18-months of follow-up. We hypothesized that group differences observed at baseline would be more pronounced after 18 months, particularly in those T1D patients with greatest exposure to glycemic extremes. Results Cognitive domain scores did not differ between groups at the 18 month testing session and did not change differently between groups over the follow-up period. However, within the T1D group, a history of diabetic ketoacidosis (DKA) was correlated with lower Verbal IQ and greater hyperglycemia exposure (HbA1c area under the curve) was inversely correlated to executive functions test performance. In addition, those with a history of both types of exposure performed most poorly on measures of executive function. Conclusions The subtle cognitive differences between T1D children and nondiabetic controls observed at baseline were not observed 18 months later. Within the T1D group, as at baseline, relationships between cognition (VIQ and executive functions) and glycemic variables (chronic hyperglycemia and DKA history) were evident. Continued longitudinal study of this T1D cohort and their carefully matched healthy comparison group is planned. PMID:26786245

Teeth plays a major role in forensic sciences especially in age assessment of an individual, which can be used to aid in criminal or civil matters. The importance of teeth comes from their ability to survive inhumation well and because they are hardly affected by exogenous and endogenous factors. Third molars are the only teeth still developing after the age of 14 years and during the legal age of adulthood, which is 18 years. The consequences of criminal violation can strongly affect the individual's life, it is important to set different parameters to decide whether an individual is a minor or an adult in the absence of documents. Depending on the different legal requirement, such parameters can set above 90% probability for criminal matters and from 51% to civil matters. The aim of this research was to find the cut-off value of third molar development for the legal age of 18 amongst Saudi individuals using the third molar maturity index method by Cameriere et al. (2008) [17]. This was a cross sectional study on 300 archived orthopantomogram (OPG) of healthy Saudi patients between the ages 14 and 22 years attending the Dental Hospital at King Saud University, Riyadh, Saudi Arabia. All OPGs were taken by PLANMECA - ProMax machine and evaluated by the Romaxis software. The inclusion criteria were good quality OPGs taken during the course of treatment. All patients were healthy with no systemic diseases or disorders with the presence of third molars and clear root apex. The lower left mandibular third molar (LL3rdM) was assessed using third molar maturity index (I3m) to determine if the individual is younger or older than 18 years old. The cut-off value of I3m for the Saudi population was (I3m<0.08). The sensitivity of this method was 51.7% and the specificity was 98.5%. Early mineralization was found in males except when I3m was ranging from (0.0 to 0.4) and (0.9 to 1.7). Cameriere et al. (2014, 2008) [16,17] test was reproducible with good measure of reliability

Exposure to indoor tanning, especially at younger ages, is associated with increased risk of skin cancer. Even in states with parental consent requirements, teenagers used tanning facilities at high rates. In 2011, California became the first state to pass a complete ban on indoor tanning by those younger than 18 years. We sought to determine whether tanning facilities in California were in compliance with the new law. In a cross-sectional study, telephone calls were placed in May 2013 to a statewide random sample of tanning facilities by a study investigator indicating that she was 17 years old. Of 600 advertised indoor tanning facilities, 338 met inclusion criteria. A majority of respondents (77%, 95% confidence interval 72%-81%) told the underage caller that she could not use their ultraviolet tanning facility. Most facilities, however, denied any dangers from ultraviolet tanning (61%) and made unlawful claims of specific health benefits, including vitamin-D production (44%), skin disease treatment (22%), prevention of future sunburns (17%), and prevention or treatment of depression (8%). Tanning facilities may respond differently to a 17-year-old's request to tan in person versus by telephone. Given strong evidence linking indoor tanning to skin cancer, and the tanning industry's documented history of marketing specifically to teenagers, this study suggests that laws banning indoor tanning younger than 18 years can meaningfully impact access. Additional enforcement, however, may be required to bring about accurate disclosure of risk and prevent claims of unproven health benefits. Copyright © 2013 American Academy of Dermatology, Inc.

This study explored the association of unemployment and an increased risk of receiving disability pension, and the possibility that this risk is attributed to municipality-specific characteristics. A cohort of 7,985 40-42 year olds was followed for 18 years in national registers, identifying new episodes of unemployment and cases of disability pension. The association between an unemployment period and disability pension in the subsequent year was estimated using discrete time multilevel logistic regressions and clustering individuals by municipality. The association between unemployment and disability pension was adjusted for age in the follow up-period, sex, baseline health status, health behaviour and education level. A conditional intra-class correlation coefficient (ICC) was estimated as a measure of inter-municipality variance. In the follow-up period, 2784 (35%) of the participants were granted disability pension. The crude odds ratio for receiving disability pension after unemployment (adjusted for age in follow-up period and sex only) was 1.42 (95% CI 1.1-1.8). Adjusting for baseline health indicators reduced the odds ratio of unemployment to 1.33 (CI 1.1-1.7). A fully adjusted model, including education level, further reduced the odds ratio of unemployment to 1.25 (CI 1.00-1.6). The ICC of the municipality level was approximately 2%. Becoming unemployed increased the risk of receiving subsequent disability pension. However, adjusting for baseline health status, health behaviour and education attenuated this impact considerably. The multilevel analysis indicated that a minor, yet statistically significant, proportion of the risk of disability pension can be attributed to the municipality of residence.

The growing population of the elderly, as well as the occurrence of coexisting diseases and polypharmacy, is the reason why diseases of patients aged $65 years belong to the major issues of the contemporary medicine. Among the most frequent diseases of the elderly, there are respiratory system diseases. They are difficult to diagnose because of the patient group specificity, which is the reason for increased mortality among seniors, caused by underdiagnosis. The study objective was to assess the factors influencing spirometry results in hospitalized patients aged ≥65 years with respiratory system disorders. In the research, 217 (100%) patients aged ≥65 years who underwent spirometry at the Regional Medical Center of the Jelenia Góra Valley Hospital in Poland were analyzed. In the statistical analysis, the STATISTICA 9.1 program, the t-test, the Shapiro-Wilk test, the ANOVA test, and the Scheffé's test were applied. The majority of the patients (59.4%) were treated in the hospital. The most frequent diagnosis was malignant neoplasm (18%). The study showed a statistically significant dependence between the forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC parameters and the time of hospitalization, as well as between the FVC and FEV1 parameters and the age of patients. The FVC parameter values turned out to be dependent on the main diagnosis. Highest results were noted in patients with the diagnosis of sleep apnea or benign neoplasm. A low FVC index can reflect restrictive ventilation defects, which was supported by the performed analyses. Highest FEV1/FVC values were observed in nonsmokers, which confirms the influence of nicotine addiction on the incidence of respiratory system diseases. The respondents' sex and the established diagnosis statistically significantly influenced the FVC index result, and the diet influenced the FEV1/FVC parameter result.

There are limited objective measures of the severity of lung disease before children are able to routinely perform spirometry, generally at age 6 years. Identifying risk factors for reduced lung function at age 6 provides opportunities to intervene and slow the progression of cystic fibrosis (CF) lung disease. To evaluate early childhood predictors of lung function at age 6-7 in a large U.S. CF cohort in the current era of widespread early eradication therapy for Pseudomonas aeruginosa (P. aeruginosa). Participants were children with CF enrolled before age 4 in the Early Pseudomonas Infection Control (EPIC) Observational Study, a multicenter, longitudinal study that enrolled P. aeruginosa-negative children not exceeding 12 years of age. Linear regression was used to estimate the association between potential early childhood risk factors and the best FEV1% predicted at age 6-7 years. Four hundred and eighty-four children (of 1,797 enrolled in the EPIC Observational Study) met the eligibility criteria for this analysis. Mean (SD) age at enrollment was 2.0 (1.3) years. In a multivariable model adjusted for age at enrollment, the following risk factors were significantly associated with lower mean (95% confidence interval) FEV1% predicted at age 6-7: weight percentile less than 10% during the year of enrollment (-5.3 [-9.1, -1.5]), P. aeruginosa positive during the year of enrollment (-2.8 [-5.7, 0.0]), crackles or wheeze during the year of enrollment (-5.7 [-9.4, -1.9]), mother's education of high school or less (-4.2 [-7.3, -1.2]), and mother smoked during pregnancy (-4.4 [-8.8, 0.1]). In this large U.S. cohort, we identified several early childhood risk factors for lower FEV1 at age 6-7 years, most of which are modifiable.

The aging precipitation behavior in Mn18Cr18N austenitic stainless steel was investigated at temperatures from 600 °C to 900 °C. During isothermal aging treatment, the primary precipitate was Cr2N with a = 0.478 nm and c = 0.444 nm, and it preferentially nucleates along initial grain boundaries and gradually grows towards the interior of grains in discontinuous cellular way. Meanwhile, a small amount of granular face-centred cubic M23C6 with a = 1.066 nm also were observed, which mainly form along grain boundaries. The effect of these precipitates on mechanical properties of the alloy was studied. It was found that precipitates result in degeneration of the matrix hardness. Meanwhile, the SEM morphologies of aged tensile sample show that the brittle fracture predominates during deformation, i.e. the fracture mode transforms from intergranular fracture to transgranular fracture with the increasing of aging time. Compared with the solution-treated sample, the strength of the aged tensile samples slightly decreases and plasticity remarkably deteriorates.
