Purpose To further understand the association between body dissatisfaction and sadness/loneliness among adolescent girls, we examine how this association, as reported by pre-teen and adolescent girls, is mediated or moderated by the quality of peer and family relationships. Methods Our data are from the Health Behavior of School-Aged Children 2009-2010, a nationally representative survey of school-aged children in the US. We analyze a sample of 5658 girls in Grades 5 through 10. We utilize ordinary least squares (OLS) regression techniques and adjust for the complex sampling design...

Information on heavy drinking over the life course might help to explain racial/ethnic disparities in alcohol-related problems, morbidity, and mortality. Using data from the 2009-2010 U.S. National Alcohol Survey (n = 3,026), we analyzed retrospective decades-based measures of heavy drinking during respondents' teens, 20s, 30s, and 40s. Results indicate that Latino men and African American women have greater risk for persistent-high (vs. declining) heavy-drinking trajectories than Caucasian men and women, and that socioeconomic disadvantage partly accounts for this disparity in women...

This qualitative study examines how youth in the San Francisco Bay Area perceive marijuana and their motives for using or not using marijuana. Current regular users were more likely to perceive marijuana smoking as an enjoyable activity, comparable to a hobby or sport. Current occasional users commonly reported smoking marijuana when it was offered to them, on special occasions, and sometimes as a result of not wanting to be left out. Most former regular users reported quitting marijuana use due to getting into trouble, being ordered into drug treatment and/or being drug tested...

MAMLD1 has been implicated in testicular function in both human and mouse fetuses. Although three patients with MAMLD1 mutations were reported to have hypergonadotropic hypogonadism in their teens, the functional significance of MAMLD1 in the postnatal testis remains unclear. Here, we analyzed the phenotype of Mamld1 knockout (KO) male mice at reproductive ages. The reproductive organs of KO male mice were morphologically unremarkable, except for relatively small testes. Seminiferous tubule size and number of proliferating spermatogonia/spermatocytes were reduced in the KO testis...

BACKGROUND: A growing number of studies suggest that bariatric surgery is safe and effective for adolescents with severe obesity. However, surprisingly little is known about changes in dietary intake and eating behavior of adolescents who undergo bariatric surgery. OBJECTIVE: Investigate changes in dietary intake and eating behavior of adolescents with obesity who underwent bariatric surgery (n = 119) or lifestyle modification (LM) (n = 169). SETTING: University-based health systems METHODS: A prospective investigation of 288 participants (219 female and 69 male) prior to bariatric surgery or LM and again 6, 12, and 24 months (surgery patients only) after treatment...

Vitamin D is thought to modulate innate immune responses, and recent studies have highlighted the autocrine and paracrine functions of vitamin D in the placenta. Our objective was to determine the relationship between maternal vitamin D status and placental antimicrobial peptide (AMP) expression in a group of racially and ethnically diverse pregnant adolescents. In this study, 158 pregnant adolescents were recruited from the Rochester Adolescent Maternity Program (RAMP) in Rochester, NY. Maternal serum concentrations of the vitamin D biomarkers, 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D), were measured at mid-gestation (∼26 weeks) and at delivery...

BACKGROUND: Most interventions designed to reduce teen pregnancy rates have not focused on pregnant and/or parenting adolescents. Therefore, a large randomized controlled trial was conducted regarding a motivational interviewing program entitled Teen Options to Prevent Pregnancy in a low income sample of adolescent mothers. This program recommended monthly sessions between a participant and a registered nurse over 18 months. This program also featured facilitated birth control access through transportation assistance and a part-time contraceptive clinic...

Vitamin D is known to regulate innate and adaptive immune processes at the cellular level, but the role of vitamin D status on associated inflammatory processes across pregnancy is unclear. Our primary objective was to evaluate the relationships between serum biomarkers of inflammation (interleukin [IL]-6, IL-10, tumor necrosis factor [TNF]-α), acute-phase proteins (C-reactive protein and hepcidin) and vitamin D status, 25-hydroxyvitamin D (25(OH)D) and 1,25-dihydroxyvitamin D (1,25(OH)2D), measured across pregnancy and in the neonate at birth...

During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43...

During 2013-2015, the percentage of children and teens aged 4-17 years who had ever received a diagnosis of ADHD was significantly higher among boys than among girls within all urbanization levels. Among boys, those living in small metro and nonmetro micropolitan areas were more likely to have received a diagnosis of ADHD (17.4% and 16.4%, respectively) than were those living in large central (11.4%) and large fringe (12.7%) metropolitan areas. Among girls, those living in large central areas were less likely to have received a diagnosis of ADHD (4...

BACKGROUND: There is very limited data available on the prevalence of Bancroftian filariasis in the Federated States of Micronesia (FSM). Considerable attempts to eliminate the disease had occurred in the Pacific region by the year 2003, and the prevalence in FSM was thought to be sufficiently low that the region was considered non-endemic. However, a survey conducted in 2003 on an isolated atoll of FSM, Satawal Island, challenged that assumption. METHODS: Participants on Satawal Island were recruited and their blood tested for Wuchereria bancrofti antigen by the filariasis immunochromatographic test (ICT) card and circulating microfilaria by Knott's concentration technique...

BACKGROUND: Adolescent medical interviewing is a difficult topic to teach and assess. Programmatic assessment has been gaining interest in medical teaching, and shifts the mode of assessment from the traditional assessment of learning (e.g. written exams) to the assessment for learning (e.g. feedback). The Structured Communication Adolescent Guide (SCAG) is a programmatic assessment tool that allows an adolescent patient to provide three types of feedback (written, numeric, grade) to a medical student in an authentic clinical workplace...

Bulimia nervosa (BN) emerges in the late teen years and is characterized by binge eating and related compensatory behaviors. These behaviors often co-occur with periods of negative affect suggesting an association between emotions and control over eating behavior. In the current study, we examined how cognitive control and neural processes change under emotional states of arousal in 46 participants with (n=19) and without (n=27) BN from the ages of 18-33 years. Participants performed a go/nogo task consisting of brief negative, positive and neutral emotional cues and sustained negative, positive and neutral emotional states of arousal during functional magnetic resonance imaging (fMRI)...

The objective of this analysis was to explore temporal and spatial variation in teen birth rates TBRs across counties in the USA, from 2003 to 2012, by using hierarchical Bayesian models. Prior examination of spatiotemporal variation in TBRs has been limited by the reliance on large-scale geographies such as states, because of the potential instability in TBRs at smaller geographical scales such as counties. We implemented hierarchical Bayesian models with space-time interaction terms and spatially structured and unstructured random effects to produce smoothed county level TBR estimates, allowing for examination of spatiotemporal patterns and trends in TBRs at a smaller geographic scale across the USA...

OBJECTIVE: Modification of sleep behaviors in teenagers has been observed over the past 30years with a reduction in overall sleep time and an increasing number of teenagers suffering from sleep deprivation. Sleep deprivation is linked to physical problems such as obesity but also to change in performance at school and mood disorders. Changes have been associated with the use of screens, cell phones, Internet and social media. Use of screens has been shown to delay sleep onset and melatonin secretion and stimulation of wake systems by interaction with social media may exacerbate these effects...

Blooms of the harmful dinoflagellate Akashiwo sanguinea are responsible for the mass mortality of fish and invertebrates in coastal waters. This cosmopolitan species includes several genetically differentiated clades. Four clonal cultures were established by isolating single cells from Xiamen Harbour (the East China Sea) for morphological and genetic analyses. The cultures displayed identical morphology but were genetically different, thus revealing presence of cryptic diversity in the study area. New details of the apical structure complex of Akashiwo sanguinea were also found...

INTRODUCTION: Hoarding disorder can cause problems with work performance, personal hygiene, health and well-being. The disorder is a growing social problem in Japan. Having difficulty discarding rubbish, decluttering and organising can signal a future hoarding disorder, and early intervention is important. We developed an educational workshop on decluttering and organising for teens and adults with difficulty organising. The objective of this study is to evaluate the effectiveness of a workshop for reducing clutter and improving quality of life among younger people with difficulty decluttering and organising...
