    Early adolescence is a time when a transition away from sport and physical activity participation is at its highest level among female youth (Hedstrom & Gould, 2004). This has led to the identification of barriers and facilitators of physical activity participation for adolescent females. Consequently there have been calls to overcome barriers and augment facilitators via the creation of gender-relevant programming. Despite these calls and efforts, a gender disparity remains, and a detailed understanding of how girls experience and interpret physical activity within the context of their lives is still lacking. The current project aimed to gain further insight into the foregoing using tenets of Interpretive Phenomenology to further understand the lived physical activity experiences of females during early adolescence, delineating their barriers to participation and the factors enabling participation. Five themes were identified and made into vignettes to facilitate understanding from adolescent females' perspectives: friends or don't know anyone, good or not good enough, fun or not fun; good feeling or gross; and peer support or peer pressure. The physical activity promotion implications for female youth are discussed within the context of these themes. Key points Please provide 3-5 bullet points of the study. Inductive qualitative methodologies can encourage the much-needed voice of female youth in sport and physical activity research. Vignettes serve, not only as a method to illustrate data, but also as a medium to teach contextually relevant information to participants and sport science service providers. The barriers and solutions to female youth engagement in physical activity are best understood through the perspectives of the intended participant. Female youth can serve as central informants in the development and analysis of research projects relating to female youth physical activity. PMID:24149121

    To evaluate the association of body image with physical activity level, body composition, and sedentary behavior (SB) of female adolescents. Exploratory cross-sectional study conducted with 120 female adolescents aged between 14-19 years, from the city of Viçosa, Minas Gerais, Southeast Brazil. Body image was evaluated with a Body Silhouette Scale (BSS) and a Body Shape Questionnaire (BSQ). Weight, height, and waist circumference values were analyzed, as well as the waist-to-height ratio and body fat percentage. The physical activity level (PAL) was assessed by 24-hour Physical Activity Recall and SB by screen time, that is, time spent in front of a TV, playing video game, on the computer and using tablets, and, separately, the cell phone time. Mean age was 16.5±1.5 years, and most adolescents were eutrophic (77.6%), sedentary/low PAL (84.2%), with high screen time (85.2%) and cell phone time (58.7%). Body dissatisfaction was stated in 40.6% of BSQ and 45.8% of BSS evaluations. Body distortion was identified in 52.9% of participants. All body composition measures, along with cell phone time and PAL, were associated with body dissatisfaction, the more active adolescents presenting higher levels of dissatisfaction. This study concluded that female adolescents with higher cell phone time also present higher body dissatisfaction, as well as the most physically active ones. All body composition measurements were associated with body dissatisfaction, mainly body mass index, waist circumference, and waist-to-height ratio.

    Participation in sport and physical activity is reported to decline during adolescence, particularly for females. However we do not have a clear understanding of changes in the context (i.e., modes and settings) of participation throughout adolescence. This study investigated longitudinal changes in physical activity participation and the specific modes and settings of physical activity, together with cross-sectional comparisons, for two age cohorts of female adolescents. Survey of 729 adolescent girls (489 recruited in Year 7 and 243 in Year 11). Participation in eight different modes/settings was reported. PA was measured using 24-h recall diary and metabolic equivalent weighted energy expenditure (MET-min) in Leisure Time Moderate and Vigorous Physical Activity (LTMVPA) on the previous day was calculated. There were no significant changes in duration or total MET-min of LTMVPA on previous day. However, there were significant changes in the modes/settings of participation across time. Participation in school physical education rose during early adolescence before decreasing significantly, and participation in competitive sport and club sport significantly decreased over time; however there were increases in non-competitive forms of physical activity. Overall levels of physical activity did not significantly decrease over adolescence, which is positive for physical health. However, the transition from structured sport to non-organised physical activity may effect social and psychological health, which needs to be further examined.

    To identify factors associated with a positive pregnancy attitude among sexually active US teen females. Secondary database analysis of the National Survey of Family Growth. Adolescent females 15-19 years old. Nationally representative sample. Bivariate and multivariable analyses were performed of the 2002 and 2006-08 cycles to examine whether sociodemographic factors, contraceptive history, sexual education and behavior history, medical services history, and family and sexual attitudes were associated with a positive pregnancy attitude among sexually active teen females. Among the 975 sexually active US adolescent females surveyed, 15% reported a positive pregnancy attitude. Compared with adolescent females with a negative pregnancy attitude, those females with a positive pregnancy attitude were significantly (P < .05) more likely to have public insurance (43% vs 20%), to be poor (33% vs 10%), to have reached menarche at an earlier age (12 years old vs 13 years old), ever have HIV tested (35% vs 23%), but less likely to have ever been forced to have sex (1% vs 10%). In multivariable analyses, Latino race/ethnicity was associated with triple the odds, and African-American double the odds, of a positive pregnancy attitude. Older age of menarche and higher family income were associated with reduced odds of a positive pregnancy attitude. One in 7 sexually active US adolescent females had a positive pregnancy attitude. Minority race/ethnicity was associated with greater odds of a positive pregnancy attitude, whereas older age of menarche and a higher family income were associated with lower odds of a positive pregnancy attitude. Assessing pregnancy attitudes for these groups of adolescent females might prove useful to decrease adolescent pregnancy rates.

    Problem Physical activity has been promoted as a means of enhancing self-concept, yet the evidence for this connection is far from compelling. In particular, experimental research investigating this association during adolescence, a period during which many youth struggle to maintain a positive self-image, is noticeably lacking. This study investigates the impact on self-concept of a 9-month physical activity intervention among sedentary adolescent females. Method Female adolescents who were sedentary at baseline were assigned either to an exercise intervention or a comparison group as part of the controlled trial. The intervention was school-based, and assignment to groups was based on school attended. Intervention participants engaged in supervised activity 4 times per week and received didactic instruction promoting activity outside of school 1 day per week. Self-concept, physical activity participation, and cardiovascular fitness were assessed before, mid-way through, and after the 9-month intervention. Results The intervention had a significant positive impact on participation in vigorous activity and cardiovascular fitness. The intervention did not significantly influence any of the self-concept dimensions overall. There was, however, a three-way interaction such that there was an increase in global physical self-concept among those intervention participants who increased cardiovascular fitness. Conclusions These findings indicate that a physical activity intervention among sedentary adolescent females enhanced global physical self-concept for a subset of intervention participants who manifested positive changes in fitness.

    Background The activPAL has been identified as an accurate and reliable measure of sedentary behaviour. However, only limited information is available on the accuracy of the activPAL activity count function as a measure of physical activity, while no unit calibration of the activPAL has been completed to date. This study aimed to investigate the criterion validity of the activPAL, examine the concurrent validity of the activPAL, and perform and validate a value calibration of the activPAL in an adolescent female population. The performance of the activPAL in estimating posture was also compared with sedentary thresholds used with the ActiGraph accelerometer. Methodologies Thirty adolescent females (15 developmental; 15 cross-validation) aged 15–18 years performed 5 activities while wearing the activPAL, ActiGraph GT3X, and the Cosmed K4B2. A random coefficient statistics model examined the relationship between metabolic equivalent (MET) values and activPAL counts. Receiver operating characteristic analysis was used to determine activity thresholds and for cross-validation. The random coefficient statistics model showed a concordance correlation coefficient of 0.93 (standard error of the estimate = 1.13). An optimal moderate threshold of 2997 was determined using mixed regression, while an optimal vigorous threshold of 8229 was determined using receiver operating statistics. The activPAL count function demonstrated very high concurrent validity (r = 0.96, p<0.01) with the ActiGraph count function. Levels of agreement for sitting, standing, and stepping between direct observation and the activPAL and ActiGraph were 100%, 98.1%, 99.2% and 100%, 0%, 100%, respectively. Conclusions These findings suggest that the activPAL is a valid, objective measurement tool that can be used for both the measurement of physical activity and sedentary behaviours in an adolescent female population.

    2002-11-01

    A four-page survey was administered to 535 adolescents at two single-sex (one male, one female) high schools in Cincinnati, Ohio, to examine whether perceptions of physical activity differed by gender. More specifically, the survey assessed perceived cues, benefits, and barriers to exercising. Results indicated that the most helpful cue to physical activity for both female and male students was "having a friend to exercise with." The most commonly reported benefit of exercising among females was "to stay in shape," whereas the most commonly reported benefit to exercising among males was "to become strong." Among females, the most common barrier to exercising was "having no time to exercise," whereas males were most likely to report "wanting to do other things with my time." Multivariate analyses of covariance revealed that perceived cues, benefits, and barriers to physical activity differed significantly based on gender. Recommendations on specific strategies to increasing male and female adolescent physical activity levels are offered.

    Knowledge of the physical activity correlate profile of adolescent females will provide insight into decreasing physical activity patterns among adolescent females. Correlates of physical activity and physical activity stage of change were assessed during 2007-2008 among 871 Irish adolescent females in years 1-6 in secondary schools (15.28 ± 1.8 years). Multivariate Analysis of Variance was used to identify whether differences in correlates of physical activity could be detected across year in school and physical activity stages of change. Significant differences (P < .01) were found in 11 of the 16 measured correlates across year in school and in 14 of the 16 correlates across stage of change. Effect size estimates and regression analysis revealed perceived competence, peer social support and intention to be physically active (partial eta range (ηp2) .21-.25) to be the most important predictors of physical activity stage of change. Females in more senior years in school and in earlier physical activity stages of change reported a significantly less positive physical activity correlate profile than females in junior years and in later physical activity stages of change. This finding supports the construct validity of the physical activity stages of change.

    In Saudi Arabia, about 14.8% of female children and adolescents of less than 20 years old are obese, compared with only 9.4% of male children and adolescents. One major factor linked to the high prevalence of obesity and related chronic illnesses involves inadequate physical activity (PA). Only 25% of female adolescents in Saudi Arabia meet the recommendation calling for 60 minutes of moderate to vigorous PA per day. The aim of this research was to examine relationships among self-reported PA and cognitive and affective variables, including perceived barriers to PA, PA self-efficacy, enjoyment of PA, social support for PA, and commitment to PA. Female Saudi adolescents 13-18 years of age were recruited from 10 public intermediate and high schools in Jeddah, Saudi Arabia. Female adolescents who met the inclusion criteria completed surveys and participated in height and weight measurements at schools. A structural equation model based on the health promotion model was estimated, with commitment to PA hypothesized to mediate relationships between health promotion model (HPM) predictors and self-reported PA. A total of 405 female adolescents with a mean age of 15.4 years took part in the study, of whom 25.3% were overweight or obese. Mean PA level measured via the Physical Activity Questionnaire for Adolescents was 2.1 (SD = 0.66), which is low. Commitment to PA partially mediated the relationships of PA self-efficacy, enjoyment of PA, and social support for PA; 25.4% of the variance in PA was explained. The model did not support the indirect relationship of perceived barriers through commitment or the direct relationship between enjoyment and PA. This study indicates that Saudi female adolescents are in need of interventions to increase their PA. The findings suggest that addressing perceived barriers to PA and targeting PA self-efficacy, enjoyment of PA, and social support for PA to enhance commitment to PA may be a fruitful approach in nursing interventions to

  14. Female sexual dysfunction and adolescents.

    2010-10-01

    To review recent publications in the area of sexual dysfunction in females including the adolescent age group. Though as many as 40% of adult females have a sexual dysfunction, the incidence among adolescent females is unknown. Though over half of adolescents are sexually active, sexual dysfunction is not a term universally accepted among the general public as well as researchers. Research on sexual dysfunction in females typically starts with age 18 years or over. Causes of sexual dysfunction include medical disorders, gynecological problems, which started from the adolescent age, psychiatric disorders, and complications of medications such as selective serotonin reuptake inhibitors (SSRIs), antipsychotics, and others. Management includes identification of the specific sexual dysfunction and treatment of the underlying condition, including surgical treatment in such cases as absent vagina or obstetrics fistula. Psychological therapy is helpful when psychological factors are contributory to the dysfunction. Pharmacologic principles of management cases can, for example, include treatment of gynecological problems such as pelvic inflammatory disease (PID) or endometriosis as a cause of sexual dysfunction or include removal of the offending drug, use of glutamatergic strategies or trazodone in SSRI-association dysfunction, and addition of bupropion or other medications in select cases. No medication is FDA-approved for sexual dysfunction in females. Sexual dysfunction in females includes lack of sexual desire, sexual pain disorders (as dyspareunia), anorgasmia, and sexual arousal dysfunction. Acceptance of the high incidence of sexual dysfunction in all female populations is necessary to appreciate this phenomenon in the adolescent cohort, because some gynecological disease can arise from the adolescent age and can cause sexual dysfunction. Some sexual dysfunctions require immediate treatment, including surgical in the case of congenital anomaly, ovarian cyst, or

    To examine the relationship between female adolescent self-esteem, decision making, and contraceptive behavior in multiethnic, 14- to 17-year-olds, residing on the Big Island of Hawaii. This was a descriptive cross-sectional survey design using a convenience sample of 98 female adolescents aged 14-17 who came to five different clinics on the Big Island of Hawaii for health care. Along with a brief demographic questionnaire, global self-esteem was measured by Rosenberg's Self-Esteem Scale, decision making was measured by the Flinders Adolescent Decision Making Questionnaire, and sexual activity and contraception use was measured by a nonnormed Sexual History and Contraceptive Use Questionnaire developed for this study. Descriptive statistics, logistic regression, and correlations were used to analyze associations and correlations between age, global self-esteem, decision self-esteem, decision coping (vigilant and maladaptive), and contraceptive use for sexually active female adolescents. No significant associations or correlations were found between age, global self-esteem, decision self-esteem, decision coping (vigilance), and the decision to use contraception in sexually active adolescent females. There was, however, significant negative correlation (p < .05) between overall maladaptive decision making and contraceptive use in sexually active female adolescents. This suggests that sexually active adolescent females with higher maladaptive scores are less likely to use contraception. There was also significant association (p < .05) between maladaptive decision making in contraceptive use and sexually active female adolescents. For every one unit increase on the maladaptive scale, the odds of using contraception were estimated to decrease by 7%. Adolescence is a period of transition that involves biological, cognitive, psychological, and social changes. During the vulnerable transition period of adolescence, decisions relating to contraception may occur

    A modified form of Nathanson and Becker's (1983) Health Belief Model Questionnaire and other measures designed to assess cognitive processing were administered to low-income black adolescent female clients of an inner-city comprehensive health care clinic. The purpose of the study was to explore determinants of sexual activity and contraceptive use. Subjects were classified as not sexually active (n = 50), sexually active/noncontracepting (n = 20), or sexually active/contracepting (n = 72). Not sexually active subjects tended to be younger, more career motivated, to have a father at home, to be more influenced by family values, and to have more conservative attitudes regarding adolescent sexuality than did sexually active subjects. Sexually active/noncontracepting subjects tended to report fewer benefits and more barriers to the use of contraception. Level of cognitive processing did not differ among the three groups, but was at a lower-than-expected level for age. Finally, inconsistent contraceptive use was common to both sexually active groups.

    Children and adolescents today are the first generation raised in a society in which technological literacy is essential for effective citizenship in the 21st century. With many more youth using digital technologies for educational and recreational purposes, there has been an increase in social problems in cyberspace, exposing them to different forms of cyberviolence. This article gives an overview of the developments in cyberspace, describes different types of cyberviolence, and focuses on cyberbullying among girls and adolescent females as both victims and perpetrators of cyberbullying. At-risk online activities among girls and adolescent females as well as strategies to promote cybersafety are presented. Current research and future directions for research are reviewed.

    2017-01-01

    Adolescence is a period of transition that is associated with increased levels of stress and a heightened propensity to initiate drug use. Neuronal development is still occurring during this transitional period, which includes the continued development of the dopamine system during the adolescent period. In the present study, the effects of pre-test handling on cocaine-induced locomotor activity were investigated among female adolescent and young adult rats upon presentation to a novel environment. On postnatal days (PND) 41–44 and 56–59 animals were handled (b.i.d.) in the colony room for 3 min. On PND 45 or PND 60, animals were removed from the colony room, weighed, and administered an acute injection of either cocaine or saline and presented to a novel environment where behavior was recorded for 30 min. Adolescent females (PND 45) that were handled prior to cocaine administration demonstrated elevated levels of cocaine-induced activity relative to their age-matched non-handled counterparts and also to their handled-adult counterparts. In contrast, among non-handled animals, young adults (PND 60) exhibited elevated drug-induced locomotion at several time points during the trial. Non-handled adolescent animals demonstrated the previously described “hyporesponsive” behavioral profile relative to their non-handled adult counterparts. The results from the present experiment indicate that adolescent animals may be more sensitive to basic laboratory manipulations such as pre-test handling, and care must be taken when utilizing adolescent animals in behavioral testing. Handling appears to be a sensitive manipulation in elucidating differences in cocaine-induced behavioral activation between ages. PMID:16176824

    Objective Activity-based anorexia is a translational rodent model that results in severe weight loss, hyperactivity, and voluntary self-starvation. The goal of our investigation was to identify vulnerable and resistant phenotypes of activity-based anorexia in adolescent female rats. Method Sprague-Dawley rats were maintained under conditions of restricted access to food (N = 64; or unlimited access, N = 16) until experimental exit, predefined as a target weight loss of 30–35% or meeting predefined criteria for animal health. Nonlinear mixed effects statistical modeling was used to describe wheel running behavior, time to event analysis was used to assess experimental exit, and a regressive partitioning algorithm was used to classify phenotypes. Results Objective criteria were identified for distinguishing novel phenotypes of activity-based anorexia, including a vulnerable phenotype that conferred maximal hyperactivity, minimal food intake, and the shortest time to experimental exit, and a resistant phenotype that conferred minimal activity and the longest time to experimental exit. Discussion The identification of objective criteria for defining vulnerable and resistant phenotypes of activity-based anorexia in adolescent female rats provides an important framework for studying the neural mechanisms that promote vulnerability to or protection against the development of self-starvation and hyperactivity during adolescence. Ultimately, future studies using these novel phenotypes may provide important translational insights into the mechanisms that promote these maladaptive behaviors characteristic of anorexia nervosa.

    2018-06-22

    Despite evidence that strength and conditioning (S&C) programs decrease injury risk and increase sport performance, young females are rarely offered S&C programs comparable to those of their male counterparts. The purpose of this study was to evaluate the current body of available literature regarding S&C in adolescent female athletes, describe potential benefits, and generate recommendations for S&C programs for female adolescent athletes. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Systematic searches of the PubMed and Google Scholar databases were conducted using the following keywords: 'female athletes,' 'injury prevention,' 'adolescent,' 'physical fitness,' 'strength,' 'female adolescent,' and 'conditioning.' Studies included in this review evaluated the effectiveness of S&C protocols and/or the habits and attitudes of coaches and athletic trainers working with female adolescent athletes. Seven articles evaluating S&C programs for the adolescent female athlete were used as the basis for this systematic review. These articles described current protocols and/or factors that should be taken into account when designing S&C programs. The identified articles focused on improving the strength of adolescent female athletes, decreasing the risk of injury, and exposing female athletes to the benefits of S&C that are routinely afforded to their male counterparts. Despite the critical potential benefits of S&C training, such as improved landing mechanics, coaches and athletic trainers do not routinely implement S&C programs for female adolescent athletes. The lack of such programs is largely due to misconceptions surrounding female athletes, such as the perception that females fear bulking up. S&C programs for adolescent female athletes should incorporate stretching of the hip adductors, targeted hamstring, gluteal and quadriceps strengthening, and a synergistic adaptation model

    Physical activity and sport can influence the extent of the presence of the postural disturbances in children. The aim of this study was to investigate the occurrence of differences in the postural disturbances in female adolescents in relation to team handball training. This investigation involved 150 female adolescents with the average age of 13.4 ± 1.5 years divided into two groups (50 adolescents trained handball and 100 did non train it). The study determined a statistically significant difference in the total number of postural disturbances between the two groups of adolescents (p < 0.001). The presence of the flat foot was statistically significantly higher in untrained adolescents (p < 0.001), but the presence of the scoliosis, kyphosis, lordosis, and pes varus was not found (p > 0.05). Handball adolescents players have less postural disturbances than untrained adolescents. Flat foot is significantly less frequent in female adolescents handball players than in untrained ones. Findings obtained in this investigation can help us in planning continuous prevention, observation and care for untrained and trained team handball female adolescents with postural disturbances.

We conducted a cross-sectional survey in 169 Kuwaiti female adolescents attending both private and public schools spanning the six governorates in the State of Kuwait in order to explore female adolescents' self-image, body dissatisfaction, type of school (private versus public), TV viewing, and computer games and their relationship to body mass index. Results. Approximately half the students classified as obese perceived their body image to lie in the normal range. Females in the obese category were the most dissatisfied with their body image, followed by those in the overweight category. Eating behavior, level of physical activity, school type, television viewing, computer/video usage, and desired BMI were not significantly associated with level of obesity. Conclusion. This study was one of the few studies to assess adolescent females' body image dissatisfaction in relation to obesity in the State of Kuwait. The results suggest that including body image dissatisfaction awareness into obesity prevention programs would be of value.

    This study investigated the association between the different types of behavior regulation and competence on sport and physical activity (PA) and perceived health, and the influence of school year level (ie, year 7 and year 11) and setting (ie, metropolitan and rural) on these relationships. A cross sectional self-complete survey was conducted. Competence was measured using the 5-item perceived competence subscale of the 21-item Athletic Identity Questionnaire (AIQ); behavior regulation was measured using a modified version of the Behavior Regulation in Exercise Questionnaire (BREQ-2); PA was measured using an item to assess if adolescents are meeting recommended levels of PA; and perceived health was measured using the Short Form 1 (SF-1). This study included 732 participants, 71.2% from metropolitan schools, and 66.8% in year 7. Self-determined behavior regulation and competence were positively associated with PA and health. Intrinsic motivation was more strongly related to older adolescents' PA than it was for younger adolescents. Behavior regulators and competence were more strongly associated with health than PA. The findings of this study suggest that strategies that enhance intrinsic motivation and PA competence may improve the health of adolescent females; enhancing these may lead to greater health regardless of level of PA.

    Social support is a consistent correlate of youth physical activity (PA) but few studies have examined this in cultural sub-groups. Female adolescents (n=113; 13.9+/-0.6years) from a metropolitan single sex private school participated in this study. PA was estimated using the 3 Day Physical Activity Recall (3dPAR), and aspects of social support using a specifically designed questionnaire. Anglo-Australians (n=74), whose parents were both born in Australia, were compared with Vietnamese-Australians (n=39), whose parents were both born in Vietnam. There were non-significant trends towards higher engagement in all measures of PA among Anglo-Australians. Anglo-Australians perceived higher levels of social support to be physically active. In the whole sample and in cultural sub-groups, support by mothers was a consistent predictor of PA. Among Vietnamese-Australians, activities shared with the mother predicted moderate to vigorous PA. Interventions targeting PA among adolescent females should consider interactions of social support and cultural background.

    Iron deficiency is more prevalent in overweight children and adolescents but the mechanisms that underlie this condition remain unclear. The purpose of this cross-sectional study was to assess the relationship between iron status and excess adiposity, inflammation, menarche, diet, physical activity, and poverty status in female adolescents included in the National Health and Nutrition Examination Survey 2003-2004 dataset. Descriptive and simple comparative statistics (t test, chi(2)) were used to assess differences between normal-weight (5th < or = body mass index [BMI] percentile <85th) and heavier-weight girls (< or = 85th percentile for BMI) for demographic, biochemical, dietary, and physical activity variables. In addition, logistic regression analyses predicting iron deficiency and linear regression predicting serum iron levels were performed. Heavier-weight girls had an increased prevalence of iron deficiency compared to those with normal weight. Dietary iron, age of and time since first menarche, poverty status, and physical activity were similar between the two groups and were not independent predictors of iron deficiency or log serum iron levels. Logistic modeling predicting iron deficiency revealed having a BMI > or = 85th percentile and for each 1 mg/dL increase in C-reactive protein the odds ratio for iron deficiency more than doubled. The best-fit linear model to predict serum iron levels included both serum transferrin receptor and C-reactive protein following log-transformation for normalization of these variables. Findings indicate that heavier-weight female adolescents are at greater risk for iron deficiency and that inflammation stemming from excess adipose tissue contributes to this phenomenon. Food and nutrition professionals should consider elevated BMI as an additional risk factor for iron deficiency in female adolescents.

    Although there have been intense efforts to reduce the prevalence of cigarette smoking in the past three decades, smoking continues to be a critical public health problem. An area of particular concern is the increasing number of young women who are smoking. Gender specific research usually does not examine factors affecting smoking behaviours. Information on late adolescent female smoking is not readily found in the literature. The aims of this study were to explore the smoking patterns and processes of late adolescent females and to explore factors which may or may not be helpful in assisting them to stop smoking. A qualitative ethnographic approach was used to uncover the perceptions of 25 adolescent girls of their behaviour. Data were collected using tape-recorded semi-structured interviews and a questionnaire. Items for the questionnaire were derived from the Manitoba Youth Smoking Survey and from the Fagerstrorn Nicotine Tolerance Scale. Qualitative analysis resulted in four stories about smoking: the start story, the smoking story, the quit story, and the looking to the future story. Although many of the findings are congruent with the existing literature, much of the data reflected the purposive nature of smoking in late adolescent girls. Study findings support the need for holistic approaches to health promotion to ameliorate factors affecting smoking behaviour.

  13. Prevalence and correlates of contraceptive use among female adolescents in Ghana.

    Adolescence is a critical stage in the life course and evidence suggests that even though contraceptive use has been steadily increasing among women in Ghana over the past years, contraceptive prevalence and determinants among female adolescents is quite lacking. This paper examines the prevalence and correlates of contraceptive use among female adolescents in Ghana. The paper used data from the 2008 Ghana Demographic and Health survey. Bivariate analysis was carried out to determine the contraceptive prevalence among female adolescents while logistic regression analysis was applied to examine the correlates of female adolescent contraceptive use. The study founded that female adolescent contraceptive use was significantly determined by age of adolescent, education, work status, knowledge of ovulatory cycle, visit of health facility and marital status. This has implications for adolescent sexual and reproductive health programmes in Ghana. It is therefore essential to intensify girl child education and strengthen the provision of family planning information and services for female adolescents in the country.

    Peak bone mass (PBM) is a negative predictor of osteoporosis and life-long fracture risk. Because osteoporosis is such a prevalent disease with life-threatening consequences later in life, it is important to try to maximize PBM. Adolescence is a critical time for bone acquisition. This review discusses some of the differences in male and female skeletal development and modifiable factors that enhance bone accrual in this age group, particularly in athletes. Hormonal influences, physical activity effects, and nutritional contributions are presented, with a focus on the adolescent athlete. Emphasis is placed on the importance of appropriate energy availability in this age group. The Female Athlete Triad (the inter-relationship of decreased energy availability, menstrual irregularity, and low bone density) is an important issue for adolescent, athletic women, and is therefore reviewed, including prevention and treatment strategies. Recommendations for maximizing bone density in both male and female adolescents are discussed. PMID:21378496

    Body image concerns are common among adolescents as they undergo rapid physical growth and body shape changes. Having a distorted body image is a risk factor for the development of disordered eating behaviours and eating disorders. This study was undertaken to investigate body image concerns among Malaysian male and female adolescents aged 11-15 years. A total of 2,050 adolescents (1,043 males and 1,007 females) with a mean age of 13.1 +/- 0.8 years from secondary schools in Kedah and Pulau Pinang were included in the study. Questionnaires were used to collect socioeconomic data and body image indicators. The majority (87 percent) of the adolescents were concerned with their body shape. While the majority of underweight, normal weight and overweight male and female subjects perceived their body weight status correctly according to their body mass index (BMI), a noteworthy proportion in each category misjudged their body weight. About 35.4 percent of the males and 20.5 percent of the females in the underweight category perceived themselves as having a normal weight, while 29.4 percent and 26.7 percent of the overweight males and females respectively also perceived that they had a normal weight. A higher proportion of the females (20 percent) than males (9 percent) with a normal BMI perceived themselves as fat. Most of the male (78-83 percent) and female subjects (69-74 percent) in all the BMI categories desired to be taller than their current height. An appreciable proportion of both the males (41.9 percent) and females (38.2 percent) preferred to remain thin, or even to be thinner (23.7 percent of males and 5.9 percent of females). Females had a significantly higher mean body dissatisfaction score than males, indicating their preference for a slimmer body shape. More males (49.1 percent) preferred a larger body size while more females (58.3 percent) idealised a smaller body size. Compared to normal weight and underweight subjects, overweight males and females

  19. Rural female adolescence: Indian scenario.

    1995-01-01

    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values.

    Traditional health education may not provide adequate sexual information to female adolescents. Sexual health education for female adolescents broadens opportunities for nurses to help female adolescents adopt appropriate sexual attitudes and make appropriate decisions. The purpose of this study was to understand the effect of sexual empowerment on sexual decision making in female adolescents. Twenty-nine female students with steady boyfriends were invited to participate in a sexual empowerment course. Course activities specifically related to sexual empowerment were audio-tape-recorded. Dialogue content was analyzed, and content provided by each study participant was reconfirmed in face-to-face interviews to understand the entire empowerment process in terms of how such may affect responses and to assess the possibility of correctly reinterpreting findings during the member check process. This study also took into consideration degrees of reliability and rigorousness. The four themes found to underlie participant perceptions of their sexual empowerment to make sex-related decisions were as follows: (a) proactively seeking sexual knowledge, (b) reexamining relationships with boyfriends, (c) the right to say "no" and to engage in self-protection, and (d) the need to change sexual attitudes and behaviors. Using the peer group intervention in sexual empowerment may positively impact sexual health decision making in adolescent girls. Nursing professionals may consider peer group intervention as a sexual empowering method in healthcare.

    Breast cancer is the most common cancer among women in Malaysia, about one in 19 women being at risk. This study aimed to investigate knowledge and practice of breast self-examination (BSE), as well as knowledge of risk factors for breast cancer amongst female adolescents in Malaysia. Subsequently, relationships between demographic characteristics and knowledge level of BSE, risk factors for breast cancer and BSE practice were assessed. A descriptive, cross sectional survey was conducted using a sample of 500 Malaysian adolescents from the age of 15 to 19 years. A self-administered questionnaire was used to gather socio- demographic characteristics, knowledge of BSE, knowledge of risk factors for breast cancer and BSE practices. The findings of this study indicated that female adolescents in Malaysia demonstrated an inadequate knowledge level of BSE and risk factors for breast cancer. Only 27.8% of female adolescents performed BSE regularly. BSE practice, knowledge of BSE and knowledge of risk factors for breast cancer showed significant positive relationships. The study highlighted the importance of planning and implementing breast health education programs for female students in secondary schools in Malaysia. It will also provide the health care providers an avenue to stress on the importance of imparting breast health education to adolescents.

    Constitutive androstane receptor (CAR) is a nuclear receptor that not only regulates drug-metabolizing enzymes but also influences energy metabolism. TC, 1, 4-bis [2-(3, 5-dichloropyridyloxy)] benzene (TCPOBOP) has been shown to inhibit lipogenesis in the liver and adipose tissues. The mammary gland is mainly composed of fat pads and duct systems in adolescent female mice. Here, activation of CAR by TC reduces the mammary gland weight, blocks lipid accumulation by inhibiting lipogenesis and gluconeogenesis, and accelerates collagen formation and fibrosis in the mammary fat pad of adolescent female mice. This information provides a reference for CAR activation, which may affect mammary gland development in adolescent females. Copyright © 2018 Elsevier B.V. All rights reserved.

    Fish is an important source of long-chain n-3 fatty acids in the diets of female adolescents, which may affect adipose tissue deposition. The purpose of this study was to evaluate fish intake in Asian and white female adolescents, and to determine whether fish intake was associated with changes in body fatness and body fat distribution in this population. A cross-sectional analysis of fish intake using 3-day food records (n=200), and a prospective analysis of baseline fish intake on anthropometric measurements 2 years later was conducted (n=103). Participants included female adolescents (aged 9 to 14 years) who were recruited from the Kaiser Permanente Oahu membership database in 2000-2001 as part of the Female Adolescent Maturation study (N=349). Fish intake and the proportion of participants eating 8 oz fish per week was compared between Asian, white, and mixed Asian/white ethnic groups using Kruskal-Wallis test, Wilcoxon rank sum test, and χ(2) test, respectively. The effect of fish intake on anthropometric measurements was assessed using Spearman's rank correlation coefficient and linear regression analyses, adjusting for demographic, pubertal, anthropometric, activity, and dietary parameters. Asians consumed more fish (0.85 oz/wk [range=0.00 to 4.74 oz/wk]) than whites (0.00 oz/wk [0.00 to 0.40 oz/wk]; P=0.0001), and were more likely to eat 8 oz fish per week (13 of 68 vs 2 of 51, respectively; P=0.014). Greater fish intake corresponded to smaller changes in waist circumference when controlling for age, ethnicity, puberty, activity, energy intake, and baseline waist circumference (P=0.026), but not after adjusting for parental and additional dietary parameters (P>0.10). Most female adolescents did not consume the recommended amount of fish, a problem that was more common in whites than Asians. The protective effect of fish intake on abdominal obesity warrants further study. Copyright © 2014 Academy of Nutrition and Dietetics. Published by Elsevier Inc. All

This is an integrative literature review, conducted from July to August 2017 on LILACS, SciELO and PubMed, using the descriptors and the MeSH terms: confrontation, violence, adolescent, pregnant women, prenatal care. The sample comprised 9 articles that were organized and characterized according to year, country of study and coping strategy used. The main forms of coping involved the active search for cases and the primary care approach with all family members. Individualized prenatal care, the change in professional training and networking activities were pointed out as important components of the strategies for coping with violence against pregnant adolescents.

    This study investigated the relationship between predisposing, reinforcing, and enabling factors conceptualized within the Youth Physical Activity Promotion Model (YPAP) and moderate to vigorous physical activity (MVPA) of adolescent males and females. Specifically, self-efficacy to overcome barriers, enjoyment of physical activity; family support, peer support, perceived school climate, neighborhood safety and access to physical activity were examined. The Physical Activity Questionnaire for Adolescents (PAQ-A) and the Actigraph 7164 were used to obtain three different measures of MVPA in 205 adolescents (102 males, 103 females). Family support emerged as the most significant and consistent factor associated with the MVPA of both adolescent males and females. This relationship was noted even when different methods of measuring MVPA were employed. These findings should increase the confidence of public health officials that family support has the potential to positively alter the physical activity behavior of adolescents. PMID:19827453

    Background: Little is known about the effectiveness of behavioral strategies to prevent long-term weight gain among adolescents and young adults. Objective: The objective was to assess the relation of dietary and physical activity weight-control strategies, alone and together, with subsequent weight change. Design: This was a prospective study of 4456 female adolescents and young adults aged 14–22 y in the ongoing Growing Up Today Study. Weight-control behaviors, including dietary approaches and physical activity, were self-reported in 2001 and were used to predict weight change from 2001 to 2005. Results: In 2001–2002, 23.7% of female adolescents and young adults were trying to maintain their weight and another 54.4% were trying to lose weight. Approximately 25% used each of the following weight-control strategies: not eating snacks, following low-calorie or low-fat diets, and limiting portion sizes. In addition, 47.7% reported exercising at least occasionally for weight control. During 4 y of follow-up, participants gained an average of 3.3 kg. None of the dietary approaches to weight control predicted less weight change; however, females who exercised ≥5 d/wk gained significantly less weight than did their peers (−0.9 kg; 95% CI: −1.4, −0.4). The most successful strategy for weight-gain prevention among the females was to limit portion sizes (−1.9 kg; 95% CI: −2.6, −1.1) combined with frequent exercise. Conclusions: Our results suggest that physical activity is a necessary strategy for long-term weight control among adolescents and young adult females. Combining dietary weight-control approaches with physical activity is the most effective method for reducing weight gain. PMID:19889827

    We explored how Thai female adolescents describe the meaning and context of dating violence. Twenty-four students, aged 15-17, were purposively recruited from a secondary school in Bangkok for individually audio-taped interviews. The interviews lasted 45- 70 minutes. ATLAS ti 5.2 was selected for content analysis. Five themes emerged, including characteristics of adolescent romantic relationships, influences on adolescent romantic relationships, perceptions of dating violence, cycle of dating-violence experiences, and influences on adolescents' perceptions of dating violence. The findings indicate a foundation for developing culturally sensitive programs for dating-violence prevention among Thai adolescents.

    To examine the association between religiosity (defined by frequency of engaging in religious/spiritual activities) and African-American adolescent females' sexual behaviors, attitudes toward sex, and ability to negotiate safer sex. Between December 1996 and April 1999, 1130 female adolescents were screened for eligibility in a sexually transmitted disease (STD)/human immunodeficiency virus (HIV) prevention trial. Data collection was achieved through a confidential self-administered questionnaire that examined religiosity and a structured interview regarding sexual behavior. Descriptive statistics were used to characterize the sociodemographics of the sample and logistic regression was used to measure the association between religiosity and the outcome variables. In the study sample (n = 522), 64% of the adolescents had higher religiosity scores based on a 4-item scale (alpha =.68). Results indicate that adolescents who had higher religiosity scores were significantly more likely to have higher self-efficacy in communicating with new, as well as steady male partners about sex; about STDs, HIV, and pregnancy prevention; and in refusing an unsafe sexual encounter. These adolescents were also more likely to have initiated sex at a later age, used a condom in the past 6 months, and possess more positive attitudes toward condom use. Results from this study indicate a relationship between religiosity and sexual behaviors, attitudes toward sex, and ability to negotiate safer sex.

    Smoking is frequently co-morbid with depression. Although it is recognized that depression increases the risk for smoking, it is unclear if early smoking exposure may increase the risk for depression. To test this possibility we assessed the effects of adolescent nicotine exposure on the Forced Swim Test (FST), which is used as a measure of passive coping, and depressive-like behavior in rodents, and on the open field test (OFT), which is used as a measure of locomotion and exploratory behavior. Male and female mice received daily saline or nicotine (0.3 or 0.6 mg/kg) injections from postnatal day (PD) 30 to PD 44. FST and OFT were performed either 1 or 30 days after the last injection (PD 45 and PD 74, respectively). In females, treatment with 0.3 mg/kg nicotine lead to increased FST immobility (64%) and decreased OFT locomotor activity (12%) one day following the last nicotine injection (PD 45); while no effects were observed in adulthood (PD 74). In contrast, on PD45, nicotine treatment did not change the male FST immobility but lead to lower OFT locomotor activity (0.6 mg/kg, 10%). In adulthood (PD 74), both nicotine doses lead to higher FST immobility (87%) in males while 0.6 mg/kg nicotine to lower OFT locomotor activity (13%). The results (i) identify females as more vulnerable to the immediate withdrawal that follows nicotine discontinuation in adolescence and (ii) suggest that adolescent nicotine exposure may enhance the risk for passive response towards unavoidable stress in adult males.

    This study aimed to examine implementation feasibility and initial treatment outcomes of a behavioral activation (BA) based treatment for adolescent depression, the Adolescent Behavioral Activation Program (A-BAP). A randomized, controlled trial was conducted with 60 clinically referred adolescents with a depressive disorder who were randomized to receive either 14 sessions of A-BAP or uncontrolled evidenced-based practice for depression. The urban sample was 64% female, predominantly Non-Hispanic White (67%), and had an average age of 14.9 years. Measures of depression, global functioning, activation, and avoidance were obtained through clinical interviews and/or through parent and adolescent self-report at preintervention and end of intervention. Intent-to-treat linear mixed effects modeling and logistic regression analysis revealed that both conditions produced statistically significant improvement from pretreatment to end of treatment in depression, global functioning, and activation and avoidance. There were no significant differences across treatment conditions. These findings provide the first step in establishing the efficacy of BA as a treatment for adolescent depression and support the need for ongoing research on BA as a way to enhance the strategies available for treatment of depression in this population.

    Due to adolescents' future crucial roles, their health needs should be included in the national health system policy. In this cross-sectional study 2010 female adolescents were recruited from randomly selected schools in Iran. To obtain their health needs, the participants completed a self-administrated questionnaire. It was revealed that emotional needs were the most important health needs of adolescents. Furthermore, there was a meaningful relationship between health needs' score with the adolescents' age and their mothers' education level. Finally, the mean score of health needs was significantly higher in urban adolescents. Therefore, it is suggested that adolescents' emotional health needs to be paid attention; otherwise irrecoverable serious problems may occur in the next generation's health.

    Experiencing romantic love is important in individual development. Little is known about romantic love among adolescents in non-Western countries. The aim of the present study was therefore to explore romantic love among Iranian female adolescents. Eighty-six females (mean age: 17.97 years) took part in the study; 38 of them (44%) indicated they were experiencing romantic love at the time of survey, and 48 (56%) indicated they were not in love. Participants completed questionnaires related to affective states and physical activity, and a sleep log for seven consecutive nights. Compared to controls, participants in love had higher scores for hypomanic-like states, positive mood, physical activity, but not for better sleep quality or for depressive symptoms. Against expectations, hypomania scores increased with the duration of the romantic relationship, suggesting that culture-related issues might shape the way romantic love may be experienced.

    The prevalence of chronic or end-stage kidney disease in pediatric girls is lower than in boys, however, girls have unique morbidities that can have great effect on their quality of life. For female adolescents, creatinine excretion peaks at approximately 14 years of age and is significantly less than males, owing to lower muscle mass. Females have higher nitric oxide activity, and estrogens may contribute to lower blood pressure. Females excrete less growth hormone during the prepubertal and pubertal years. Females between the ages of 8 and 10 years show increased levels of parathyroid hormone and vitamin D, however, female adolescents with chronic kidney disease have less estrogen and loss of the luteinizing hormone pulsatile pattern. These biological, hormonal, and physical changes affect the psychosocial aspects of female adolescents with chronic kidney disease/end-stage kidney disease, and they must learn to manage their health to achieve good outcomes. Patients and their parents must learn disease management through a customized health care transition preparation in both the pediatric- and adult-focused settings. Clinical strategies are suggested for the care of these special patients. Copyright © 2017. Published by Elsevier Inc.

    Recent research indicates environmental factors and personal behaviors are related to breast cancer risk, but adopting a healthy lifestyle as early as adolescence can serve a protective function. To investigate perceptions of breast cancer risk and the environment, 10 focus groups (N = 91) were conducted with adolescent females (n = 55) and mothers (n = 36) across four counties in the Midwest, USA. The Uncertainty Management Theory provides a framework for discussing statements, and results suggest that uncertainty is maintained through ambiguity about environmental risk factors and breast cancer. Recommendations for prevention messages are presented. PMID:18987091

    Physical activity (PA) declines as adolescents get older, and the motivational determinants of PA warrant further investigation. The purposes of this study were to investigate the amount of physical and sedentary activity that adolescents participated in across age, gender, and race, and to investigate adolescents' attraction to PA and their perceived barriers and benefits across age, gender, and race. High school students (N = 1163) aged between 13 and 16 years completed questionnaires on minutes and intensity of physical and sedentary activity, interests in physical activity, and perceived benefits and barriers to participating in PA. A series of multivariate analyses of variance were conducted and followed up with discriminant function analysis. PA participation decreased in older females. In addition, fun of physical exertion was a primary attraction to PA for males more than females. Body image as an expected outcome of participating in PA contributed most to gender differences. There is a need to determine why PA drops-off as females get older. Findings underscore the importance of structuring activities differently to sustain interest in male and female adolescents, and highlights motives of having a healthy body image, and making PA fun to enhance participation.

    The present study was conducted to develop a Multi-dimensional Body Image Scale for Malaysian female adolescents. Data were collected among 328 female adolescents from a secondary school in Kuantan district, state of Pahang, Malaysia by using a self-administered questionnaire and anthropometric measurements. The self-administered questionnaire comprised multiple measures of body image, Eating Attitude Test (EAT-26; Garner & Garfinkel, 1979) and Rosenberg Self-esteem Inventory (Rosenberg, 1965). The 152 items from selected multiple measures of body image were examined through factor analysis and for internal consistency. Correlations between Multi-dimensional Body Image Scale and body mass index (BMI), risk of eating disorders and self-esteem were assessed for construct validity. A seven factor model of a 62-item Multi-dimensional Body Image Scale for Malaysian female adolescents with construct validity and good internal consistency was developed. The scale encompasses 1) preoccupation with thinness and dieting behavior, 2) appearance and body satisfaction, 3) body importance, 4) muscle increasing behavior, 5) extreme dieting behavior, 6) appearance importance, and 7) perception of size and shape dimensions. Besides, a multidimensional body image composite score was proposed to screen negative body image risk in female adolescents. The result found body image was correlated with BMI, risk of eating disorders and self-esteem in female adolescents. In short, the present study supports a multi-dimensional concept for body image and provides a new insight into its multi-dimensionality in Malaysian female adolescents with preliminary validity and reliability of the scale. The Multi-dimensional Body Image Scale can be used to identify female adolescents who are potentially at risk of developing body image disturbance through future intervention programs. PMID:20126371

    Physical inactivity is a leading cause of mortality worldwide. Many patterns of physical activity involvement are established early in life. To date, the role of easily identifiable early-life individual predictors of PA, such as childhood temperament, remains relatively unexplored. Here, we tested whether childhood temperamental activity level, high intensity pleasure, low intensity pleasure, and surgency predicted engagement in physical activity (PA) patterns 11 years later in adolescence. Data came from a longitudinal community study (N = 206 participants, 53% females, 70% Caucasian). Parents reported their children's temperamental characteristics using the Child Behavior Questionnaire (CBQ) when children were 4 & 5 years old. Approximately 11 years later, adolescents completed self-reports of PA using the Godin Leisure Time Exercise Questionnaire and the Youth Risk Behavior Survey. Ordered logistic regression, ordinary least squares linear regression, and Zero-inflated Poisson regression models were used to predict adolescent PA from childhood temperament. Race, socioeconomic status, and adolescent body mass index were used as covariates. Males with greater childhood temperamental activity level engaged in greater adolescent PA volume (B = .42, SE = .13) and a 1 SD difference in childhood temperamental activity level predicted 29.7% more strenuous adolescent PA per week. Males' high intensity pleasure predicted higher adolescent PA volume (B = .28, SE = .12). Males' surgency positively predicted more frequent PA activity (B = .47, SE = .23, OR = 1.61, 95% CI: 1.02, 2.54) and PA volume (B = .31, SE = .12). No predictions from females' childhood temperament to later PA engagement were identified. Childhood temperament may influence the formation of later PA habits, particularly in males. Boys with high temperamental activity level, high intensity pleasure, and surgency may directly seek out pastimes that involve PA

    Exergame use (or active video games that promote physical activity [PA]) has the potential to increase PA in youth, but there is a scarcity of information about PA of youth who are current exergamers. The current study examined PA behaviors in exergamers versus nonexergamers. Adolescents (N = 2,793; mean age = 14.4 ± 2.0 years) participating in EAT 2010 (Eating and Activity in Teens) self-reported sociodemographic characteristics and exergaming and PA behavior. Height and weight were measured. Both male and female exergamers tended to be younger and black compared with nonexergamers (p < .001). Generally, exergamers did not report significantly more PA than nonexergamers, except for female exergamers who engaged in more vigorous PA than female nonexergamers (p < .01; 1.3 ± .05 h/wk vs. 1.6 ± .06 h/wk, respectively). PA behavior in exergamers is similar to PA behavior in nonexergamers. However, when targeting vigorous PA, exergaming may be an innovative and appealing intervention strategy for adolescent girls.

    This study examines individual and family characteristics of a population of 29 adolescent females charged with homicide or attempted homicide in the juvenile justice system. The purpose of this study is to contribute to the limited knowledge about adolescent females charged with homicide. Data were collected including the MAYSI-2, a risk classification instrument, and social, educational and family histories. Findings include high rates of reported substance use, delinquent peers, early indicators of mental health problems, and limited control and supervision by parents. The most common weapon used was a car and the most common victim was a known person. A comparison was conducted on girls charged with homicide during the commission of another crime or committed during a conflict. The conflict group was found to victimize friends and family significantly more often than the crime group. The crime group showed higher use of alcohol and drugs, used a gun more and had co-offenders at a higher rate. A profile was developed to describe the typical adolescent female homicide offender found in this study. Treatment recommendations and future research were discussed.

    Prior research has documented favorable effects of active and educational videogames among adolescents. However, research on potential negative effects of such games is limited. Scholars have called attention to games portraying sexualized female characters. The purpose of the current study was to experimentally investigate the effect of playing a videogame with a sexualized female character on adolescents' acceptance of rape myths and tolerance for sexual harassment. Fifty-seven secondary school pupils, 12-15 years of age, participated in a 2 (gender: boys versus girls)×2 (game character: nonsexualized versus sexualized female) factorial design experiment. Participants played a game for 15 minutes and were randomly assigned to one of the two game characters. Afterward, they completed established scales to assess rape myth acceptance and tolerance for sexual harassment. Analyses of variance showed greater acceptance of rape myths (P=0.039) and greater tolerance of sexual harassment (P=0.046) in adolescents who played with the sexualized woman compared with adolescents in the control condition. We did not find significant differences between boys and girls or any interaction effect between gender and game character. Findings suggest that gameplaying with a sexualized woman may increase adolescents' acceptance of rape myths and tolerance for sexual harassment. These findings highlight attention to the use of sexualized female game characters in (educational and active) videogames that target adolescents.

    During adolescence, rats gain independence from their mothers and disperse from the natal burrow, with males typically dispersing further than females. We predicted that, if dispersal patterns are associated with responsiveness to novelty, exploratory behavior in novel environments would increase across adolescence, and males would explore more than females. Alternatively, females might explore more than males, if females are more motivated than males to learn about the immediate environment or if females have poorer spatial abilities than males. Twenty-five male and 21 female rats were exposed to two novel environments (open field and elevated plus-maze) during early, mid-, or late adolescence. Total locomotion and amount of exploration directed towards aversive areas increased across adolescence, even when body weight was included as a covariate. Female adolescents locomoted more and spent more time exploring aversive areas than males. Developmental changes in neural function potentially underlie age and sex differences in exploratory behavior. © 2009 Wiley Periodicals, Inc. Dev Psychobiol 51: 513–520, 2009. PMID:19582791

    Activity-based anorexia (ABA) is a widely used animal model for identifying the biological basis of excessive exercise and starvation, two hallmarks of anorexia nervosa (AN). Anxiety is correlated with exercise in AN. Yet the anxiety level of animals in ABA has not been reported. We asked: Does food restriction as part of ABA induction change the anxiety level of animals? If so, is the degree of anxiety correlated with degree of hyperactivity? We used the open field test before food restriction and the elevated plus maze test (EPM) during food restriction to quantify anxiety among singly housed adolescent female mice and determined whether food restriction alone or combined with exercise (i.e., ABA induction) abates or increases anxiety. We show that food restriction, with or without exercise, reduced anxiety significantly, as measured by the proportion of entries into the open arms of EPM (35.73 %, p= .04). Moreover, ABA-induced individuals varied in their open arm time measure of anxiety and this value was highly and negatively correlated to the individual’s food restriction-evoked wheel activity during the 24 hours following the anxiety test (R = − .75, p= .004, N = 12). This correlation was absent among the exercise-only controls. Additionally, mice with higher increase in anxiety ran more following food restriction. Our data suggest that food restriction-evoked wheel running hyperactivity can be used as a reliable and continuous measure of anxiety in ABA. The parallel relationship between anxiety level and activity in AN and ABA-induced female mice strengthens the animal model. PMID:25730124

    Alcohol use has been linked to risky sexual practices among adolescents. However, limited research on alcohol use and risky sexual behavior has been conducted among female adolescents. This study examined a high quantity of alcohol as a longitudinal predictor of risky sexual behavior and sexually transmitted diseases (STDs) among female adolescents. Three hundred ninety-three adolescent females aged 15-21 were assessed for alcohol use and risky sexual behaviors. Participants also provided 2 swab specimens that were assayed for STDs. Use of high alcohol quantity was defined as > or = 3 drinks in 1 sitting. Binary generalized estimating equation models were conducted assessing the impact of alcohol use at baseline on risky sexual behavior and STDs over a 12-month period. Age, intervention group and baseline outcome measures were entered as covariates. The results indicated that use of high alcohol quantity predicted inconsistent condom use, high sexual sensation seeking, multiple sexual partners, sex while high on alcohol or drugs, and having anal sex during 12-month follow-up period. These findings suggest that STD-related behavioral interventions for adolescents should discuss the link between alcohol and STD-risk behavior. Deeper understanding of alcohol as a predictor of risky sexual behavior among female adolescents is of paramount importance for development of efficient prevention programs at individual and community levels. The risk of acquiring an STD is higher among teenagers than among adults.

    Because sustained physical activity is important for a healthy life, this paper examined whether a greater diversity of sport activities during adolescence predicts higher levels of leisure-time physical activity (LTPA) in adulthood. From sport activity participation reported by 17-year-old twins, we formed five groups: 1, 2, 3, 4, and 5+ different sport activities. At follow-up in their mid-thirties, twins were divided into four activity classes based on LTPA, including active commuting. Multinomial regression analyses, adjusted for several confounders, were conducted separately for male (N=1288) and female (N=1770) participants. Further, conditional logistic regression analysis included 23 twin pairs discordant for both diversity of sport activities in adolescence and LTPA in adulthood. The diversity of leisure-time sport activities in adolescence had a significant positive association with adulthood LTPA among females. Membership in the most active adult quartile, compared to the least active quartile, was predicted by participation in 2, 3, 4, and 5+ sport activities in adolescence with odds ratios: 1.52 (P=.11), 1.86 (P=.02), 1.29 (P=.39), and 3.12 (P=5.4e-05), respectively. Within-pair analyses, limited by the small sample of twins discordant for both adolescent activities and adult outcomes, did not replicate the association. A greater diversity of leisure-time sport activities in adolescence predicts higher levels of LTPA in adulthood in females, but the causal nature of this association remains unresolved. © 2017 John Wiley & Sons A/S.

    We previously observed that social instability stress (SS: daily 1 h isolation and change of cage partners for 16 days) in adolescence, but not in adulthood, decreased context and cue memory after fear conditioning in male rats. Effects of stress are typically sex-specific, and so here we investigated adolescent and adult SS effects in females on the strength of acquired contextual and cued fear conditioning, as well as extinction learning, beginning either the day after the stress procedure or four weeks later. For SS in adolescence, SS females spent more time freezing (fear measure) during extinction than did controls, whereas SS in adulthood had no effect on any measure of fear conditioning. The results also indicated an effect of age: females in late adolescence show more rapid extinction of cue and better memory of extinction of context compared to adult females, which may indicate resilience to acute footshock in adolescence. Thus fear circuitry continues to mature into late adolescence, which may underlie the heightened plasticity in response to chronic stressors of adolescents compared to adults.

    Patellofemoral pain is one of the most common conditions seen in sports medicine practices, particularly among adolescent females. However, the natural history of the underlying pathology in patellofemoral pain during puberty remains poorly understood. The purpose of this longitudinal study is to assess changes in patellar maltracking patterns in subjects with patellofemoral pain as they mature from mid- to late adolescence. Cohort study; Level of evidence, 3. Three-dimensional patellofemoral kinematic data were acquired during active knee extension-flexion using dynamic magnetic resonance imaging in 6 girls (10 knees; mean age, 14.0 years) with clinically diagnosed patellofemoral pain. The subjects then returned as late adolescents (mean age, 18.5 years) for follow-up scanning. Three-dimensional patellofemoral kinematic parameters were evaluated across the range of motion, but comparison between time points was restricted to 10° of flexion. Participation in impact and nonimpact physical activities, pain score based on the visual analog scale, and the anterior knee pain score were also compared across initial and follow-up visits. All subjects reported improved patellofemoral pain symptoms at follow-up, and one subject reported complete resolution. However, relative to the initial visit, no differences were found in patellar maltracking. There was a decrease in hours engaged in impact physical activities for all subjects at follow-up. This study provides insight into the natural history of patellofemoral pain in adolescent females. The relatively unchanged patellofemoral maltracking across subjects suggests that potential anatomic and kinematic abnormalities contributing to patellofemoral pain during mid-adolescence persist during skeletal maturation. Symptom improvement for these subjects did not result from a change in patellofemoral tracking, but rather from other causes.

    Physical activity has been identified as a protective factor with regard to tobacco use, such that physically active adolescents are less likely to initiate smoking, and smokers are less physically active than non-smokers. These findings, along with the well-documented benefits of exercise on mood and well-being in adults, have stimulated interest in exercise-based smoking cessation interventions. However, little research has explored the relationship between physical activity and smoking characteristics within adolescent smokers. Also, gender differences in adolescents’ motives for smoking and exercise may have implications for intervention development, especially in clinical populations. The current study explored the relationship between physical activity and smoking in a sample of adolescent smokers (N = 191) and non-smokers (N = 48) receiving inpatient psychiatric treatment (61% female, mean age 15.3 years). Results indicated that smokers were less likely to be physically active than non-smokers. Additionally, there was a consistent pattern of gender differences in the relationship between smoking and physical activity within smokers. Specifically, physically active male smokers were less nicotine dependent and less prone to withdrawal, and had a trend toward greater motivation to quit, than their non-active counterparts. In contrast, physically active female smokers did not differ in dependence or withdrawal and were less motivated to quit than non-active female smokers. Taken together, these results suggest that within clinical populations of adolescent females, smoking and exercise may be used jointly as weight control strategies. Exercise-based interventions for smoking cessation for adolescent females, especially clinical populations, should address weight and body image concerns. PMID:23459125

    This paper investigated weight misperceptions as determinants of racial/ethnic disparities in body mass index (BMI) among adolescent females using data from the National Survey of Youth 1997. Compared to their white counterparts, higher proportions of black and Hispanic adolescent females underperceived their weight status; that is, they misperceived themselves to have lower weight status compared to their clinically defined weight status. Compared to their black counterparts, higher proportions of white and Hispanic adolescent females misperceived themselves to be heavier than their clinical weight status. Oaxaca-Blinder decomposition analysis showed that accounting for weight misperceptions, in addition to individual and contextual factors, increased the total explained portion of the black-white female BMI gap from 44.7% to 54.3% but only slightly increased the total explained portion of the Hispanic-white gap from 62.8% to 63.1%. Weight misperceptions explained 13.0% of the black-white female BMI gap and 3.3% of the Hispanic-white female BMI gap. The regression estimates showed that weight underperceptions were important determinants of adolescent female BMI, particularly among black and Hispanic adolescents. Education regarding identification and interpretation of weight status may play an important role to help reduce the incidence and racial disparity of female adolescent obesity. PMID:22701166

    To examine differences in factors associated with contraceptive use between younger and older adolescent age groups, which has not previously been well described. Age group-specific analyses were performed on cross-sectional survey data to identify factors associated with any contraceptive use at last sex among younger (14- to 16-year-old) and older (17- to 19-year-old) sexually active African American female adolescents; interaction analyses were used to assess whether these associations differed by age. Adolescent reproductive health clinic in Atlanta, Georgia. Sexually active African American female adolescents 14-19 years of age. No intervention tested; cross-sectional design. Self-reported contraceptive use during most recent vaginal sex with a male partner. The prevalence of contraceptive use at last sex was identical in both groups; however, factors associated with contraceptive use differed according to age. The only factor associated with contraceptive use in both age groups was involvement in decisions about sexual health in the most recent relationship. Associations between factors and contraceptive use significantly differed according to age. History of sexually transmitted infection, age difference with partner, discussion of condoms with partner, and concurrent partners were important factors among younger adolescents; worry about pregnancy and discussion of birth control with partner were important among older adolescents. Factors associated with contraceptive use at last sex differ according to adolescent age; this should be considered when designing counseling and interventions for teens, as well as research.

    This study explored post-migration experiences of recently migrated Pakistani Muslim adolescent females residing in the United States. In-depth, semi-structured interviews were conducted with thirty Pakistani Muslim adolescent females between the ages of 15 and 18 years living with their families in Houston, Texas. Data obtained from the interviews were evaluated using discourse analysis to identify major reoccurring themes. Participants discussed factors associated with the process of adaptation to the American culture. The results revealed that the main factors associated with adaptation process included positive motivation for migration, family bonding, social support networks, inter-familial communication, aspiration of adolescents to learn other cultures, availability of English-as-second-language programs, participation in community rebuilding activities, and faith practices, English proficiency, peer pressure, and inter-generational conflicts. This study provided much needed information on factors associated with adaptation process of Pakistani Muslim adolescent females in the United States. The results have important implications for improving the adaptation process of this group and offer potential directions for intervention and counseling services.

    Prior research has identified reduced reward-related brain activation as a promising endophenotype for the early identification of adolescents with major depressive disorder (MDD). However, it is unclear whether reduced reward-related brain activation constitutes a true vulnerability for MDD. One way of studying vulnerability is through a high-risk design. Therefore, the aim of the current study was to determine whether reward-related activation of the ventral striatum is reduced in nondepressed daughters of mothers with a history of MDD (high-risk) similarly to currently depressed adolescent girls, compared with healthy controls. By directly comparing groups with a shared risk profile during differing states, we aimed to shed light on the endophenotypic nature of reduced reward processing for adolescent depression. We compared reward-related neural activity through functional magnetic resonance imaging (fMRI) between three groups of female biological offspring (N = 52) of mothers with differential MDD status: (a) currently depressed daughters of mothers with a history of MDD (MDD group; n = 14), (b) age- and socioeconomic status (SES)-matched never-depressed daughters of mothers with a history of MDD (high-risk group; n = 19), and (c) age- and SES-matched control daughters of mothers with no past or current psychopathology in either the mother or the daughter (healthy control group; n = 19). For the outcome phase of the reward task, right-sided ventral striatum activation was reduced for both currently depressed and high-risk girls compared with healthy controls. This ventral striatal activity correlated significantly with maternal depression scores. These findings provide further evidence of aberrant functioning for the United States Department of Health & Human Services, National Institutes of Health, National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC)-defined domain of positive valence systems as a vulnerability factor for MDD and a

    This study investigates spatial and nonspatial working memory, anxiety related behavior, and motor activities in cadmium and/or nicotine exposed female adolescent mice. P28 female adolescent mice (albino strain) were divided into four groups of five (n = 5) mice each. A set of mice (Nic) received subcutaneous nicotine (2.0 mg/kg) while a separate set (Cd) was treated with 2.0 mg/kg cadmium (subcutaneous). For the combined treatments of cadmium and nicotine, we administered 2.0 mg/kg Nicotine and 2.0 mg/kg of Cd. Subsequently, a separate group of animals (n = 5; control) received normal saline. The total duration of treatment for all groups was 28 days (P28–P56). At P56, the treatment was discontinued, after which the animals were examined in behavioural tests. Nicotine and cadmium increased the metabolism and food intake in the female adolescent mice. This also corresponded to an increase in weight when compared with the control. However, a combined nicotine-cadmium treatment induced a decline in weight of the animals versus the control. Also, nicotine administration increased the motor function, while cadmium and nicotine-cadmium treatment caused a decline in motor activity. Both nicotine and cadmium induced a reduction in memory index; however, nicotine-cadmium treatment induced the most significant decrease in nonspatial working memory. PMID:25477708

    This study was conducted to examine if fluoxetine, a selective 5-hydroxytryptamine (5-HT) reuptake inhibitor, would reverse adverse behavioral effects of neonatal maternal separation in female rats. Sprague-Dawley pups were separated from dam daily for 3h during postnatal day (PND) 1-14 (maternal separation; MS) or left undisturbed (non-handled; NH). Female NH and MS pups received intraperitoneal injection of fluoxetine (10mg/kg) or vehicle daily from PND 35 until the end of the whole experimental period. Rats were either subjected to behavioral tests during PND 44-54, or sacrificed for neurochemical analyses during PND 43-45. Daily food intake and weight gain of both NH and MS pups were suppressed by fluoxetine, with greater effects in MS pups. MS experience increased immobility and decrease swimming in forced swim test. Swimming was increased, although immobility was not significantly decreased, in MS females by adolescence fluoxetine. However, adolescence fluoxetine increased immobility during forced swim test and decreased time spent in open arms during elevated plus maze test in NH females. Fluoxetine normalized MS-induced decrease of the raphe 5-HT levels and increased 5-HT metabolism in the hippocampus in MS females, and increased the hypothalamic 5-HT both in NH and MS. Fluoxetine decreased the raphe 5-HT and increased the plasma corticosterone in NH females. Results suggest that decreased 5-HTergic activity in the raphe nucleus is implicated in the pathophysiology of depression-like behaviors, and increased 5-HTergic activities in the raphe-hippocampus axis may be a part of anti-depressant efficacy of fluoxetine, in MS females. Also, an extra-hypothalamic 5-HTergic activity may contribute to the increased anorectic efficacy of fluoxetine in MS females. Additionally, decreased 5-HT in the raphe and elevated plasma corticosterone may be related with fluoxetine-induced depression- and/or anxiety-like behaviors in NH females.

    The objective of this study is to examine the association between physical and sexual violence exposure and somatic symptoms among female adolescents. We studied a nationally representative sample of 8,531 females, aged 11-21 years, who participated in the 1994-1995 Wave I of the National Longitudinal Study of Adolescent Health (Add Health). Female adolescents were asked how often they had experienced 16 specific somatic symptoms during the past 12 months. Two summary categorical measures were constructed based on tertiles of the distributions for the entire female sample: (a) total number of different types of symptoms experienced, and (b) number of frequent (once a week or more often) different symptoms experienced. Groups were mutually exclusive. We examined associations between adolescents' violence exposure and somatic symptoms using multinomial logistic regression analyses. About 5 % of adolescent females reported both sexual and non-sexual violence, 3 % reported sexual violence only, 36 % reported non-sexual violence only, and 57 % reported no violence. Adolescents who experienced both sexual and non-sexual violence were the most likely to report many different symptoms and to experience very frequent or chronic symptoms. Likelihood of high symptomatology was next highest among adolescents who experienced sexual violence only, followed by females who experienced non-sexual violence only. Findings support an exposure-response association between violence exposure and somatic symptoms, suggesting that symptoms can be markers of victimization. Treating symptoms alone, without addressing the potential violence experienced, may not adequately improve adolescents' somatic complaints and well-being.

    Background: Anger and aggression belong to the core symptoms of borderline personality disorder. Although an early and specific treatment of BPD is highly relevant to prevent chronification, still little is known about anger and aggression and their neural underpinnings in adolescents with BPD. Method: Twenty female adolescents with BPD (age 15–17 years) and 20 female healthy adolescents (age 15–17 years) took part in this functional magnetic resonance imaging (fMRI) study. A script-driven imagery paradigm was used to induce rejection-based feelings of anger, which was followed by descriptions of self-directed and other-directed aggressive reactions. To investigate the specificity of the neural activation patterns for adolescent patients, results were compared with data from 34 female adults with BPD (age 18–50 years) and 32 female healthy adults (age 18–50 years). Results: Adolescents with BPD showed increased activations in the left posterior insula and left dorsal striatum as well as in the left inferior frontal cortex and parts of the mentalizing network during the rejection-based anger induction and the imagination of aggressive reactions compared to healthy adolescents. For the other-directed aggression phase, a significant diagnosis by age interaction confirmed that these results were specific for adolescents. Discussion: The results of this very first fMRI study on anger and aggression in adolescents with BPD suggest an enhanced emotional reactivity to and higher effort in controlling anger and aggression evoked by social rejection at an early developmental stage of the disorder. Since emotion dysregulation is a known mediator for aggression in BPD, the results point to the need of appropriate early interventions for adolescents with BPD. PMID:29632476

    To estimate the proportion of physically active adolescents and identify associated factors. The sample was composed of 2,874 high school students (public and private schools) aged 14 to 19 years in the city of João Pessoa, Northeastern Brazil. Physical activity level was measured by means of a questionnaire and considered physically active if > 300 minutes/week. Sociodemographic variables were analyzed, as well as nutritional status, sedentary behavior, self-report of health status and participation in physical education classes. The prevalence ratio was used as association measure, estimated by means of Poisson regression. The prevalence of physical activity was 50.2% (95%CI: 47.3;53.1). Male adolescents were more physically active than female adolescents (66.3% vs. 38.5%; p<0.001). The factors directly associated with practice of physical activity were: father's higher level of schooling for the male sex and mother's higher level of schooling for the female sex, positive self-reported health status, and participation in physical education classes. The majority of the adolescents was classified as physically active, particularly the male youths. Adolescents with parents whose level of schooling was higher, with positive health status perception, and who participated in physical education classes were more likely to be physically active.

    In the United States, black women are at much greater risk for obesity than black men. We explored whether adolescent behaviors (family dinners, hours of television, playing sports with mother, playing sports with father, bouts of physical activity) were associated with gender disparity in 6-year obesity incidence in young adulthood. We used data from the nationally representative National Longitudinal Study of Adolescent Health to examine adolescent behaviors in nonimmigrant black (n = 1,503) and white (n = 4,452) youths in 1994-95 (aged 11-19 years) and 1995-96 (aged 12-20). We assessed gender disparity in obesity incidence (female incidence minus male incidence) during young adulthood (2001-02; aged 18-26). Standardized gender disparities were calculated using race- and gender-stratified, covariate-adjusted logistic regression models in which males and females were set to the same distributions of adolescent behaviors. In adolescence, black females reported less leisure-time physical activity and lower likelihood of playing sports with either parent compared with black males. Setting adolescent behaviors equal for black males and females did not reduce the estimated gender disparity in obesity incidence (nonstandardized: 9.8 percentage points (95% confidence interval (CI): 4.5, 15.1); fully standardized: 10.2 percentage points (5.2, 15.2)). There was little gender disparity in whites before or after adjustments. To our knowledge, this is the first study to examine to what extent behavioral differences during adolescence might account for gender disparity in obesity incidence in black young adults. Male-female differences in these adolescent behaviors did not appear to underlie the gender gap in young adult obesity.

    Background Little is known about the actual physical activity and screen time behaviors of an adolescent’s friends relative to the individual’s behavior. Purpose To determine the associations between an adolescent’s physical activity and screen time and his/her nominated friends’ physical activity and screen time. Methods Data were obtained from EAT 2010 (Eating and Activity Among Teens), a large cross-sectional study (n=2126) conducted in 20 middle schools and high schools in Minneapolis/St. Paul MN during the 2009–2010 academic year and analyzed during 2011. Each participant nominated up to six friends from a school roster, and data from those friends were obtained as part of the school-based data collection procedures. Physical activity and screen time were assessed with previously used and validated questionnaires. Generalized estimating equation models, stratified by gender, were used to assess associations between adolescents’ physical activity and screen time and their friends’ physical activity and screen time. Results Physical activity for female adolescents was associated with their male and female friends’ physical activity, including their male and female best friends (all p<0.05). Males’ physical activity was associated with their female friends’ physical activity (p<0.03). Females’ screen time was associated with their male and female friends’ screen time (p≤0.03), but not with that of their best friends. Males’ screen time was associated with only their female friends’ screen time (p=0.04). Conclusions The consistent association between female adolescents’ physical activity and their friends’ physical activity indicates a need to include peer effects on adolescent female physical activity in future intervention work.

    The late adolescent period is characterized by marked neurodevelopmental and endocrine fluctuations in the transition to early adulthood. Adolescents are highly responsive to the external environment, which enhances their ability to adapt and recover from challenges when given nurturing influences, but also makes them vulnerable to aberrant development when exposed to prolonged adverse situations. Female rats are particularly sensitive to the effects of chronic stress in adolescence, which manifests as passive coping strategies and blunted hypothalamo-pituitary adrenocortical (HPA) stress responses in adulthood. We sought to intervene by exposing adolescent rats to environmental enrichment (EE) immediately prior to and during chronic stress, hypothesizing that EE would minimize or prevent the long-term effects of stress that emerge in adult females. To test this, we exposed male and female rats to EE on postnatal days (PND) 33-60 and implemented chronic variable stress (CVS) on PND 40-60. CVS consisted of twice-daily unpredictable stressors. Experimental groups included: CVS/unenriched, unstressed/EE, CVS/EE and unstressed/unenriched (n = 10 of each sex/group). In adulthood, we measured behavior in the open field test and forced swim test (FST) and collected blood samples following the FST. We found that environmental enrichment given during the adolescent period prevented the chronic stress-induced transition to passive coping in the FST and reversed decreases in peak adrenocortical responsiveness observed in adult females. Adolescent enrichment had little to no effect on males or unstressed females tested in adulthood, indicating that beneficial effects are specific to females that were exposed to chronic stress.

    In Latin America, more than 80% of adolescent girls are physically inactive. Inactivity may be reinforced by female stereotypes and objectification in the Latin American sociocultural context. We examined the influence of objectification on the adoption of an active lifestyle among 192 adolescents (14 and 17 years old) from urban and rural areas in Costa Rica. Analyses of 48 focus-groups sessions were grounded in Objectification Theory. Vigorous exercises were gender-typed as masculine while girls had to maintain an aesthetic appearance at all times. Adolescents described how girls were anxious around the prospect of being shamed and sexually objectified during exercises. This contributed to a decrease in girls' desire to engage in physical activities. Among males, there is also a budding tolerance of female participation in vigorous sports, as long as girls maintained a feminine stereotype outside their participation. Self-objectification influenced Costa Rican adolescent girls' decisions to participate in physical activities. Interventions may include: procuring safe environments for physical activity where girls are protected from fear of ridicule and objectification; sensitizing boys about girl objectification and fostering the adoption of a modern positive masculine and female identities to encourage girls' participation in sports.

    Binge drinking is prevalent during adolescence, and its effect on neurocognitive development is of concern. In adult and adolescent populations, heavy substance use has been associated with decrements in cognitive functioning, particularly on tasks of spatial working memory (SWM). Characterizing the gender-specific influences of heavy episodic drinking on SWM may help elucidate the early functional consequences of drinking on adolescent brain functioning. Forty binge drinkers (13 females, 27 males) and 55 controls (24 females, 31 males), aged 16 to 19 years, completed neuropsychological testing, substance use interviews, and an SWM task during functional magnetic resonance imaging. Significant binge drinking status × gender interactions were found (p < 0.05) in 8 brain regions spanning bilateral frontal, anterior cingulate, temporal, and cerebellar cortices. In all regions, female binge drinkers showed less SWM activation than female controls, while male bingers exhibited greater SWM response than male controls. For female binge drinkers, less activation was associated with poorer sustained attention and working memory performances (p < 0.025). For male binge drinkers, greater activation was linked to better spatial performance (p < 0.025). Binge drinking during adolescence is associated with gender-specific differences in frontal, temporal, and cerebellar brain activation during an SWM task, which in turn relate to cognitive performance. Activation correlates with neuropsychological performance, strengthening the argument that blood oxygen level-dependent activation is affected by alcohol use and is an important indicator of behavioral functioning. Females may be more vulnerable to the neurotoxic effects of heavy alcohol use during adolescence, while males may be more resilient to the deleterious effects of binge drinking. Future longitudinal research will examine the significance of SWM brain activation as an early neurocognitive marker of alcohol impact to the

    The aim of the study was to examine the gender differences and predictors of leisure versus non-leisure time physical activities among Saudi adolescents aged 14-19 years. The multistage stratified cluster random sampling technique was used. A sample of 1,388 males and 1,500 females enrolled in secondary schools in three major cities in Saudi Arabia was included. Anthropometric measurements were performed and Body Mass Index was calculated. Physical activity, sedentary behaviours and dietary habits were measured using a self-reported validated questionnaire. The total time spent in leisure and non-leisure physical activity per week was 90 and 77 minutes, respectively. The males spent more time per week in leisure-time physical activities than females. Females in private schools spent more time during the week in leisure-time physical activities, compared to females in Stateschools. There was a significant difference between genders by obesity status interaction in leisure-time physical activity. Gender, and other factors, predicted total duration spent in leisure-time and non-leisure-time physical activity. The study showed that female adolescents are much less active than males, especially in leisure-time physical activities. Programmes to promote physical activity among adolescents are urgently needed, with consideration of gender differences.

    Background While males constitute the majority, female adolescent offenders are a sizeable minority of the overall delinquent population. Further, those females who become involved in delinquent activities appear to be doing so at a younger age, and they are involved in a wide range of criminal activities, including violent offenses. Objective The goal of this article is to consolidate an empirical base for our current knowledge about female juvenile offenders’ trauma-related mental health and rehabilitation issues. Method We searched for studies using PILOTS, PsycLIT, PsycINFO, and EBSCOhost electronic databases. Results Accordingly, we present a review of findings from 33 recent studies showing consistently high rates of trauma exposure, PTSD, and common comorbidities among female adolescent offenders. We also examined recent literature on risk and protective factors for female delinquency, as well as treatments for offenders, and found that there was some early representation of trauma and PTSD as important variables to be considered in etiology and treatment. Conclusion Future plans for addressing the mental health needs of female offenders should be better informed by these recent findings about widespread trauma exposure and related psychological consequences.

    This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia. We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model. Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia. The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents' risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

    Anorexia nervosa (AN) is a psychiatric illness characterized by restricted eating and irrational fears of gaining weight. There is no accepted pharmacological treatment for AN, and AN has the highest mortality rate among psychiatric illnesses. Anorexia nervosa most commonly affects females during adolescence, suggesting an effect of sex and hormones on vulnerability to the disease. Activity-based anorexia (ABA) is a rodent model of AN that shares symptoms with AN, including over-exercise, elevation of stress hormones, and genetic links to anxiety traits. We previously reported that ABA in adolescent female rats results in increased apical dendritic branching in CA1 pyramidal cells of the ventral hippocampus at postnatal day 44 (P44). To examine the long-term effects of adolescent ABA (P44) in female rats, we compared the apical branching in the ventral hippocampal CA1 after recovery from ABA (P51) and after a relapse of ABA (P55) with age-matched controls. To examine the age-dependence of the hippocampal plasticity, we examined the effect of ABA during adulthood (P67). We found that while ABA at P44 resulted in increased branching of ventral hippocampal pyramidal cells, relapse of ABA at P55 resulted in decreased branching. ABA induced during adulthood did not have an effect on dendritic branching, suggesting an age-dependence of the vulnerability to structural plasticity. Cells from control animals were found to exhibit a dramatic increase in branching, more than doubling from P44 to P51, followed by pruning from P51 to P55. The proportion of mature spines on dendrites from the P44-ABA animals is similar to that on dendrites from P55-CON animals. These results suggest that the experience of ABA may cause precocious anatomical development of the ventral hippocampus. Importantly, we found that adolescence is a period of continued development of the hippocampus, and increased vulnerability to mental disorders during adolescence may be due to insults during this

    Despite substantial increases in the prevalence of adolescent overweight and obesity documented in recent decades, few studies have prospectively tracked their development during the entire adolescent period. The aims of this study were to characterize developmental trends in prevalence, incidence, and remission of overweight and obesity using annual data collected from ages 12 to 19 for 496 adolescent females. Ethnic differences between African American (n = 37), Latina (n = 96), and European American (n = 348) adolescents were also compared. The prevalence of overweight decreased slightly across adolescence and remission rates exceeded incidence (onset). Obesity was more chronic, with increasing incidence accompanied by decreasing remission rates. Middle through late adolescence was the period of greatest risk for the transition from overweight to obesity. African American and Latina females had higher overweight and obesity prevalence than European American females throughout adolescence. Differences in prevalence were driven by higher onset rates for African American and Latina females, whereas remission rates were comparable across ethnic groups. Results suggest that adolescence is not a high-risk period for onset of obesity for European American adolescent females, but is for African American and Latina adolescent females. PMID:21499888

    To identify the role of the nurse practitioner in caring for female adolescents with type 1 diabetes mellitus at risk for disordered eating behaviour and to formulate clinical recommendations for nurse practitioners in the primary care setting. Transition into adulthood can be difficult for female adolescents with type 1 diabetes mellitus. Challenges associated with management of this illness may place adolescent females at an increased risk for disordered eating. Discussion paper. Sourced literature from 1991-2013, located through CINAHL, Health Source, Proquest, PubMed, PsychInfo, Web of Science and Medline databases. Nurses involved in the primary care of female adolescents with type 1 diabetes mellitus need to be aware of the increased risk for disordered eating behaviours and develop the competencies to care for both the adolescent and her family to reduce the serious consequences of these behaviours. Awareness and acquisition of the skills required to intervene will enable nurse practitioners to recognize clients at risk for disordered eating, gain appreciation of the motivation of female adolescents with type 1 diabetes mellitus towards disordered eating behaviours and give optimal opportunity for education, counselling and recovery. Future direction for research includes exploration of the experiences of adolescents with type 1 diabetes mellitus; early interventions in the primary care setting; effective educational, preventative or supportive services for adolescents with this illness and their families; and outcomes to emerging technologies for insulin therapy on disordered eating occurrence. © 2014 John Wiley & Sons Ltd.

    In the United States, Black women are at much greater risk for obesity than Black men. We explored whether adolescent behaviors (family dinners, hours of television, playing sports with mother, playing sports with father, bouts of physical activity) were associated with gender disparity in six-year obesity incidence in young adulthood. We used data from the nationally representative National Longitudinal Study of Adolescent Health to examine adolescent behaviors in non-immigrant Black (n=1503) and White (n=4452) youths in 1994–95 (aged 11–19 years) and 1995–96 (aged 12–20). We assessed gender disparity in obesity incidence (female incidence minus male incidence) during young adulthood (2001–02; aged 18–26). Standardized gender disparities were calculated using race- and gender-stratified, covariate-adjusted logistic regression models in which males and females were set to the same distributions of adolescent behaviors. In adolescence, Black females reported less leisure-time physical activity and lower likelihood of playing sports with either parent than Black males. Setting adolescent behaviors equal for Black males and females did not reduce the estimated gender disparity in obesity incidence (non-standardized: 9.8 percentage points [95% CI: 4.5, 15.1]; fully-standardized: 10.2 percentage points [5.2, 15.2]). There was little gender disparity in Whites before or after adjustments. To our knowledge, this is the first study to examine to what extent behavioral differences during adolescence might account for gender disparity in obesity incidence in Black young adults. Male-female differences in these adolescent behaviors did not appear to underlie the gender gap in young adult obesity. PMID:19875993

    To evaluate the convergent validity of the PAQ-A for assessing physical activity (PA) in overweight (including obese) adolescents. Two hundred and three Spanish adolescents (96 females), aged 13-17 years, were selected for this study. Levels of PA were self-reported by 3-day activity diary, activity rating and PAQ-A. Adolescents wore the ActiGraph accelerometer for 7 days. Overweight was classified according to International Obesity Task Force age- and sex-specific body mass index cut offs. Fifty-four (33 male and 21 female) adolescents (27%) were classified as overweight or obese. The PAQ-A was moderately related in the overweight adolescent group to an activity rating (ρ=0.52), total PA and moderate-to-vigorous PA assessed by activity monitor (ρ=0.52 and 0.43) and total PA and moderate-to-vigorous PA assessed by activity diary (ρ=0.32 and 0.47). There were no significant differences in the correlation coefficients between non-overweight and overweight adolescents. The PAQ-A shows a reasonable validity for assessing PA in Spanish overweight adolescents. Copyright © 2010 Elsevier España, S.L. All rights reserved.

  12. Female masturbation in adolescence and the development of the relationship to the body.

    PubMed

    Laufer, M E

    1982-01-01

    The significance of the role played by masturbation in the female is examined from a developmental point of view in order to question the assumption, often made, that female masturbation has the same normal significance as masturbation for the male. In order to do so, the difference between attitudes to male and female masturbation is defined as a difference in attitude to the use of the hand for masturbatory activity and is related to the observation that it is that activity that female children give up post-oedipally and again in post-puberty. The unconscious meaning of the hand, as identified with the mother's active handling of the child's body, is examined to show that masturbation is needed by the child to internalize a positive narcissistic cathexis of the body as well as a means of separating from the mother's body. The continued use of the hand during adolescence and adulthood by the girl or woman is then seen as a defensive means of maintaining a positive relationship to her own sexual body once the girl's body has become identified with that of her mother. The failure of this defence when used by the girl as a means to maintain a positive relationship to her own sexual body is seen as leading to the unconsciously determined need to attack her body, as can be observed clinically in those adolescents who physically attack their body.

    Recent research has highlighted the presence of Young's Early Maladaptive Schemas (EMSs) in individuals with an eating disorder (ED). This study assessed the EMSs reported by adolescent females with Anorexia Nervosa (AN) compared with a community group. Thirty-six adolescent females diagnosed with AN or subthreshold AN and 111 female secondary school students completed a questionnaire that included the Young Schema Questionnaire, the Behavior Assessment System for Children Self-report of Personality, and the Eating Disorder Screen for Primary Care. Two independent AN subtypes and two community subtypes were derived from responses to the questionnaire, and significant differences between the four comparison groups were found. High Pathology AN participants reported the highest level of psychological maladjustment. Social Isolation and Emotional Inhibition appeared to be most characteristic of adolescent AN in this sample. The results suggest that EMSs may require attention in the treatment of AN in adolescent females, and that different AN subtypes may require individualized treatment approaches.

  14. Adolescent opiate exposure in the female rat induces subtle alterations in maternal care and transgenerational effects on play behavior.

    The non-medical use of prescription opiates, such as Vicodin(®) and MSContin(®), has increased dramatically over the past decade. Of particular concern is the rising popularity of these drugs in adolescent female populations. Use during this critical developmental period could have significant long-term consequences for both the female user as well as potential effects on her future offspring. To address this issue, we have begun modeling adolescent opiate exposure in female rats and have observed significant transgenerational effects despite the fact that all drugs are withdrawn several weeks prior to pregnancy. The purpose of the current set of studies was to determine whether adolescent morphine exposure modifies postpartum care. In addition, we also examined juvenile play behavior in both male and female offspring. The choice of the social play paradigm was based on previous findings demonstrating effects of both postpartum care and opioid activity on play behavior. The findings revealed subtle modifications in the maternal behavior of adolescent morphine-exposed females, primarily related to the amount of time females' spend nursing and in non-nursing contact with their young. In addition, male offspring of adolescent morphine-exposed mothers (MOR-F1) demonstrate decreased rough and tumble play behaviors, with no significant differences in general social behaviors (i.e., social grooming and social exploration). Moreover, there was a tendency toward increased rough and tumble play in MOR-F1 females, demonstrating the sex-specific nature of these effects. Given the importance of the postpartum environment on neurodevelopment, it is possible that modifications in maternal-offspring interactions, related to a history of adolescent opiate exposure, plays a role in the observed transgenerational effects. Overall, these studies indicate that the long-term consequences of adolescent opiate exposure can impact both the female and her future offspring.

    The age of stressor exposure can determine its neurobehavioral impact. For example, exposure of adolescent male rats to resident-intruder stress impairs cognitive flexibility in adulthood. The current study examined the impact of this stressor in female rats. Rats were exposed to resident-intruder stress during early adolescence (EA), mid-adolescence (MA) or adulthood (Adult). They were tested in an operant strategy-shifting task for side discrimination (SD), reversal learning (REV) and strategy set-shifting (SHIFT) the following week. Performance varied with age, stress and coping style. MA and EA rats performed SD and SHIFT better than other ages, respectively. Social stress impaired performance in rats depending on their coping strategy as determined by a short (SL) or long (LL) latency to become subordinate. SL rats were impaired in SD and REV, whereas EA-LL rats were impaired in SHIFT. These impairing effects of female adolescent stress did not endure into adulthood. Strategy set-shifting performance for female adolescents was positively correlated with medial prefrontal cortex (mPFC) activation as indicated by c-fos expression suggesting that this region is engaged during task performance. This contrasts with the inverse relationship between these indices reported for male adolescent rats. Together, the results demonstrate that social stress produces cognitive impairments for female rats that depend on age and coping style but unlike males, the impairing effects of female adolescent social stress are immediate and do not endure into adulthood. Sex differences in the impact of adolescent social stress on cognition may reflect differences in mPFC engagement during the task. Copyright © 2015 Elsevier B.V. All rights reserved.

    1997-01-01

    This article describes the different preferences in learning styles of adolescent females and males, based on the pioneering work on adolescent values development by Lawrence Kohlberg and Carol Gilligan. Since values education programs are currently considered very important, educators need to explore the philosophical, psychological, and social influences on students' learning preferences before they can introduce appropriate curricula. An indication of problems in adolescent females frequently is the occurrence of voice changes, for example, girls may express viewpoints that do not represent their true beliefs and feelings. Curricular and co-curricular suggestions are presented.

    Staphylococcus saprophyticus is a rarely reported agent of urinary tract infection (UTI) in the pediatric population. In our retrospective 3-year study, S. saprophyticus comprised 24.5% of 106 isolates of UTIs in female adolescents 12-15 years of age who attended an emergency department. Clinicians should be aware of the high prevalence of this etiology when empirically treating UTIs in female adolescents.

    Breast development in the female is a process that becomes noticeable during puberty, and defines a girl's transition into adulthood. Various conditions can disrupt or alter the normal development, which may lead to abnormal breast changes and features. Further, the finding of a breast mass in adolescence can be unsettling to the patient and her family. While the majority of these breast changes and/or masses tend to be benign and self-limited, the appropriate evaluation is always warranted. This chapter will focus on the normal and abnormal development of breasts. We will also discuss the evaluation and management of breast masses that can be found in the adolescent female.

    A sedentary lifestyle is increasingly implicated in a negative metabolic health profile among youth. The present study examined relationships between clustered metabolic risk factors and TV viewing in female adolescents. The sample comprised 262 girls 14-17 years. Height, weight, fasting glucose, insulin, HDL cholesterol, triglycerides, and blood pressure were measured. Body mass index (BMI) was calculated. TV viewing time and moderate-to-vigorous physical activity (MVPA) were estimated from a 3-day diary. Outcome variables were normalized and expressed as Z scores which were summed into a metabolic risk score. Multiple linear regression analysis was used. TV viewing was independently associated with increased prevalence of clustered metabolic risk in girls after adjustment for several confounders (i.e., chronological age, BMI, MVPA, and parental education). The final model also indicated that lower levels of MVPA, higher BMI, and lower mother education were associated with higher metabolic risk. Increased TV viewing had an adverse effect on metabolic health of adolescent girls. The findings highlight the potential importance of preventive actions to ameliorate metabolic risk in youth which target both sedentary and physically active behaviors.

    Obesity has been linked to high dietary intake and low physical activity. Studies showed that those factors were not only regulated by environment but also by genetic. However, the relationship is less been understood in obese children and adolescents. The objective of this study was to examine the role of SNPs in GHSR rs292216 and rs509035 on dietary intake in obese female adolescents. This is an observational study with cross sectional design. Respondents were obese female adolescents enrolled from obesity screening done in six junior high schools in Yogyakarta. Dietary intake was measured using 6 days 24 hours inconsecutive dietary recall. Genotyping of 2 SNPs from GHSR was done using FRLP-PCR. There were 78 obese female adolescents joined this study. We found that no significant association between SNPs GHSR and dietary intake (p < 0.05). In addition, a SNP-SNP interaction analysis shown there is no difference between combination of GHSR rs292216 and rs509035 on dietary intake (p < 0.05). We concluded that SNPs on GHSR rs292216 and rs509035 were not related to dietary intake in Indonesian obese female adolescents. Further study is necessary to investigate the effect of those genes on dietary intake in the broader population.

    To test the hypothesis that low socioeconomic status (SES), a disturbed parent-daughter relationship, early sexual development, and antisocial behavior are risk factors in adolescent females affiliating with adult male sexual partners. To determine whether the relation between these risk factors and affiliating with adult male sexual partners is stronger in females with greater, rather than fewer, substance use disorders (SUD). Subjects were 180 adolescent females with SUD and 87 normal controls (14-18 years of age). The SUD group had a lower SES and more negative parent-daughter interactions, and exhibited greater antisocial tendencies. Also, the SUD group showed a more frequent affiliation with adult male sexual partners. Chronological age, age of menarche (sexual development), antisocial behavior, and quality of the parent-daughter relationship were significantly associated with affiliation with adult male sexual partners. Moreover, the number of SUD diagnoses enhanced the relation between the quality of the parent-daughter relationship and antisocial behavior with affiliation with adult male sexual partners. From a prevention perspective, interventions directed at enhancing child rearing practices, communication skills, and involvement in children's needs and activities might result in improved parent-child attachments that may attentuate young women's propensities to become involved in antisocial behavior and affiliate with adult sexual partners. Also, the risk imposed by an early sexual maturation may be offset by enhancing the female adolescent's social skills to select non-deviant and supportive male partners.

    This study was conducted to examine the effects of adolescence social isolation on food intake and psycho-emotional behaviors of female rats. Female littermates were either single-caged (social isolation) or group-caged (control) from postnatal day 28, and then subjected to behavioral sessions during postnatal day 50-53. Body weight gain of the isolates was accelerated during the experimental period and food intake was persistently greater than group-caged controls from postnatal day 35. Isolated females showed a selective increase in cookie intake when they had additional cookie access to standard chow. The isolates exhibited hyperactivity with increased ambulatory counts and rearings during the activity test as compared with group-caged controls. Behavioral scores of the elevated plus maze test did not differ between the isolates and group-caged controls; however, immobility time during the forced swim test was significantly increased in the isolates. Basal levels of plasma corticosterone were elevated, but the corticosterone increase responding to an acute stress was blunted, in the isolates compared with group-caged ones. Results suggest that adolescence social isolation induces hyperphagia and depression-like behaviors in female rats and a tonic increase of plasma corticosterone may be implicated in its underlying mechanisms.

    Over the last years, heavy ethanol consumption by teenagers/younger adults has increased considerably among females. However, few studies have addressed the long-term impact on brain structures’ morphology and function of chronic exposure to high ethanol doses from adolescence to adulthood in females. In line with this idea, in the current study we investigated whether heavy chronic ethanol exposure during adolescence to adulthood may induce motor impairments and morphological and cellular alterations in the cerebellum of female rats. Adolescent female Wistar rats (35 days old) were treated with distilled water or ethanol (6.5 g/kg/day, 22.5% w/v) during 55 days by gavage. At 90 days of age, motor function of animals was assessed using open field (OF), pole, beam walking and rotarod tests. Following completion of behavioral tests, morphological and immunohistochemical analyses of the cerebellum were performed. Chronic ethanol exposure impaired significantly motor performance of female rats, inducing spontaneous locomotor activity deficits, bradykinesia, incoordination and motor learning disruption. Moreover, histological analysis revealed that ethanol exposure induced atrophy and neuronal loss in the cerebellum. These findings indicate that heavy ethanol exposure during adolescence is associated with long-lasting cerebellar degeneration and motor impairments in female rats.

    Hock, R A; Curry, J F

    1983-12-01

    The historical view of masculinity/femininity posited essentially bipolar opposites, with the presence of one set of characteristics precluding the other. More recent studies of sex-role stereotypes have defined sexual orientation within clusters of socially desirable attributes which males and females perceive as differentiating males from females. This view negates the contention that psychological sex roles are composed of bipolar opposites, and concludes that the constructs of masculinity and femininity are independent dimensions rather than a single bipolar dimension. Little is known about the sex-role functioning of adolescents, yet it is during adolescence that qualitative shifts occur in interpersonal relationships and concurrent changes occur in cognitive functioning, with adolescents shifting toward hypothetical thinking and abstract ideal notions. In view of these changes, much can be learned about adult functioning by studying the sex-role perceptions of adolescents related to familial and social variables. This study examines the sex-role perceptions that adolescents hold of fathers, mothers, ideal males, ideal females, and selves. Differences exist between male and female adolescents, and significant linkages exist between sex-role identification and academic achievement.

    To generate a grounded theory about female adolescent behaviour in the sun. Nurses have key roles in health promotion and skin cancer prevention. Adolescents' resistance to sun safety messages and their vulnerability to sunburn are of concern internationally. Understanding why young women do as they do in the sun may enhance skin cancer prevention, but their behaviour has not been explained before in the UK. The study incorporated a qualitative grounded theory design using the approach of Glaser. Qualitative data were gleaned from group and one-to-one, semi-structured interviews with 20 female participants aged 14-17, research memos and literature. Sampling was purposive and theoretical. Data collection, analysis and theory generation occurred concurrently. Data were analysed using the constant comparative method. Data collection ended when a substantive theory had been generated. Data analysis revealed five categories of findings: fitting in, being myself, being physically comfortable, slipping up and being comfortable (the core category). The theory generated around the core explains how young women direct their sun-related activities towards meeting their physical and psychosocial comfort needs. A contribution of this research is the grounded theory explaining the behaviour of young women in the sun. Further, the theory challenges assumptions that female adolescents necessarily take risks; it explains their sun-related activities in terms of comfort. The theory extends findings from other researchers' descriptive qualitative studies and also appears to apply to young people in countries other than the UK. Understanding the sun-related activity of young women in terms of physical and psychosocial comfort may help nurses to develop new approaches to skin cancer prevention. These could complement existing messages and humanise health promotion. © 2013 John Wiley & Sons Ltd.

    This study used latent class analysis to identify patterns (i.e., classes) across a broad range of online sexual experiences among female adolescents (n = 312) and to explore offline sexual behavior and substance use correlates of as well as maltreatment differences in class membership. The following four classes were identified: Online Abstinent, Online Inclusive, Attractors, and Seekers. Maltreated female adolescents were more likely to be members of the Online Inclusive class and less likely to be members of the Online Abstinent class than nonmaltreated female adolescents. Offline sexual behaviors and substance use differentially predicted class membership. These results suggest online sexual experiences vary greatly and should not be aggregated together as a global risk factor for all female adolescents. © 2017 Society for Research on Adolescence.

    The present study examined components of adolescents' social environment (social network, extracurricular activities, and family relationships) in association with depression. A total of 332 adolescents presenting for a routine medical check-up were self-assessed for social network risk (i.e., smoking habits of best male and female friends), extracurricular activity level (i.e., participation in organized sports teams, clubs, etc.), family relationship quality (i.e., cohesion and conflict), and symptoms of depression (i.e., minimal, mild, moderate/severe). Results of a forward linear regression modeling indicate that social environment components were associated with a significant proportion of the variance in adolescent depression (Adjusted R (2) = .177, p < or = .05). Specifically, adolescent females (beta = .166, p < .01) and those having more smokers in their social network (beta = .107, p < .05) presented with significantly greater depression symptoms. Conversely, adolescents who engaged in more extracurricular activities (beta = -.118, p < .05) and experienced higher quality family relationships (beta = -.368, p < .001) presented with significantly lower depressive symptoms. These findings highlight the important role that the social environment plays in adolescent depression, as well as yields new insights into socially-based intervention targets that may ameliorate adolescent depression. These intervention targets may be gender-specific, include positive social network skills training, increase adolescents' engagement in organized activities, and attend to the quality of their family relationships.

    The 5-year survival rate for childhood cancer is over 80%, thereby increasing the number of young women facing infertility in the future because of the gonadotoxic effects of chemotherapy and radiation. The gonadotoxic effects of childhood cancer treatment vary by the radiation regimen and the chemotherapeutic drugs utilized. Although the American Society of Clinical Oncology guidelines recommend fertility preservation for all patients, there are several barriers and ethical considerations to fertility preservation in the pediatric and adolescent female population. Additionally, the fertility preservation methods for pre- and postpubertal females differ, with only experimental methods available for prepubertal females. We will review the risk of chemotherapy and radiation on female fertility, the approach to fertility preservation in the pediatric and adolescent female population, methods of fertility preservation for both pre- and postpubertal females, barriers to fertility preservation, cost, and psychological and ethical considerations.

    High rates of adolescent pregnancy, sexually transmitted infections, and unsafe abortions in Nigeria indicate the need for a greater understanding of factors that affect adolescent sexuality. The sexual health needs of adolescents remain poorly known and addressed particularly among vulnerable subpopulations like out-of-school adolescents. The objective of this study was to examine the sexual behavior of female out-of-school adolescents and to identify factors that influence their sexual behavior. This cross-sectional study was conducted among a representative sample of unmarried, out-of-school female adolescents (n = 332, mean age 17 y), selected using cluster sampling, who were working in a major market (Mushin) in Lagos, Nigeria. Data were collected using interviewer administered questionnaires. Many girls (43.7%) have had sexual intercourse. The mean age at initiation was 16 years. The main reason for initiation was curiosity. Risky sexual behavior and transactional sex was common. Nonconsensual sex was also reported. Sexual health knowledge was poor, and friends served as their main source of information on sexual health issues. Factors associated with the initiation of sexual activity were friends sexual behavior, the person adolescents reside with, parents marital status, availability of funds to meet basic needs, and watching pornography (p < .05). Out-of-school female adolescents engaging in risky sexual behavior are exposed to sexual abuse, lack skills to resist pressure, and have limited access to credible reproductive health information. Appropriate interventions including provision of sexuality education and a supportive environment must be instituted to address their needs.

    Within the past one and half decades many efforts have been made to improve the availability and access to adolescent sexual and reproductive health services. Despite these efforts, adolescents still face a number of sexual and reproductive health problems. This paper uses data from the 2003 and 2008 Ghana Demographic and Health Surveys to examine changes in contraceptive use among sexually active female adolescents (15-19 years old). The results show that between 2003 and 2008 there was a significant increase in the current use of any contraceptive method (from 23.7% to 35.1%, p = 0.03). It also indicates a shift from modern to traditional contraceptive methods. Traditional methods recorded about 60% (7.8 percentage points) increase as compared to 5.5% (2.6 percentage points) for modern methods. Also ever use of any traditional method recorded a higher increase as compared to any modem method. There was a slight decline 7% (4.4 parentage points) in the number of non-users who intended to use contraceptives in the future. On the whole the findings indicate increasing unmet need for modern contraception due to barriers such as limited access, cost and misconceptions about the effects of contraceptives.

    This article explores information relating to female adolescents knowledge, attitudes, and behaviors toward human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs) in Carriacou. The authors aimed at finding out whether adolescent females in Carriacou receive adequate information about HIV and other STDs. Where did students receive most of their information about HIV/STDs and whether the knowledge has influenced their sexual behaviors? Furthermore, this study focused on how female adolescents feel toward people living with HIV/STDs.Focus group method was employed with 2 age groups of female adolescent students. Content analysis was carried out by the researcher to analyze the data. Themes were developed using coding and thematic analysis.The findings revealed that female adolescents were highly aware of HIV/STDs-related facts. They were knowledgeable and have received adequate information about HIV/STDs.

    The aim of this study was to investigate heart rate variability (HRV) in a clinical sample of female adolescents with anxiety disorders (AD) and/or major depressive disorder (MDD) compared with healthy controls and to assess the effect of selective serotonin reuptake inhibitors (SSRI) on HRV. Heart rate variability was measured in adolescent female psychiatric patients with AD and/or MDD (n = 69), mean age 16.8 years (range: 14.5-18.4), from 13 out-patient clinics and in healthy controls (n = 65), mean age 16.5 years (range: 15.9-17.7). HRV was registered in the sitting position during 4 min with no interventions. Logarithmically transformed high frequency HRV (HF), low frequency HRV (LF) and standard deviation of inter beat intervals (SDNN) were lower in the clinical sample compared with the controls (Cohen's d for HF = 0.57, LF = 0.55, SDNN = 0.60). This was not explained by body mass index, blood pressure or physical activity. Medication with SSRI explained 15.5% of the total variance of HF, 3.0% of LF and 6.5% of SDNN. Adolescent female psychiatric patients with AD and/or MDD show reduced HRV compared with healthy controls. Medication with SSRI explained a part of this difference.

  20. Adolescent Activity-Based Anorexia Increases Anxiety-Like Behavior in Adulthood

    2010-01-01

    Activity-based anorexia is a paradigm that induces increased physical activity, reduced food intake, and heightened activity of the hypothalamic-pituitary-adrenal axis in adult rats. To investigate whether experience with activity-based anorexia produced enduring effects on brain and behavior, female adolescent rats experienced activity-based anorexia during adolescence and were tested in adulthood for anxiety-like behavior on an elevated plus maze and in an open field. Analysis of elevated plus maze and open field behavior in adulthood revealed that rats that experienced activity-based anorexia during adolescence, but not rats that were simply food restricted, displayed increased anxiety-like behavior in adulthood. Plasma corticosterone and expression levels of corticotropin- releasing hormone mRNA in the hypothalamic paraventricular nucleus and in the central nucleus of the amygdala were significantly elevated in adult rats that had undergone activity-based anorexia in adolescence in response to the open field exposure, as compared to control rats. These data demonstrate enduring effects of adolescent activity-based anorexia on anxiety-like behavior and neuroendocrine factors critical in stress responsivity in adulthood. Furthermore, we demonstrate that activity-based anorexia during adolescence serves as a model whereby prolonged anxiety is induced, allowing for evaluation of the behavioral and neural correlates of mediating anxiety-like behaviors in adulthood.

    Objective: To evaluate the inappropriate eating behaviors (IEB) of female adolescents over a one-year period. Methods: 290 adolescents aged between 11 and 14 years old participated in the three research stages (T1: first four months, T2: second four months and T3: third four months). The Eating Attitudes Test (EAT-26) was applied to assess the IEB. Weight and height were measured to calculate body mass index (BMI) in the three study periods. Analysis of variance for repeated measures was used to analyze the data, adjusted for the scores of the Body Shape Questionnaire and the Brazil Economic Classification Criteria. Results: Girls at T1 showed a higher frequency of IEB compared to T2 (p=0.001) and T3 (p=0.001). The findings also indicated higher values for BMI in T3 in relation to T1 (p=0.04). The other comparisons did not show statistically significant differences. Conclusions: IEB scores of female adolescents declined over one year. PMID:24676195

    This study examined how factors associated with body image predict regular smoking in adolescent females. Data were from the National Longitudinal Study of Adolescent Health (Add Health), a study of health-related behaviors in a nationally representative sample of adolescents in grades 7 through 12. Females in Waves I and II (n=6,956) were used for this study. Using SUDAAN to adjust for the sampling frame, univariate and multivariate analyses were performed to investigate if baseline body image factors, including perceived weight, perceived physical development, trying to lose weight, and self-esteem, were predictive of regular smoking status 1 year later. In univariate analyses, perceived weight (p<.01), perceived physical development (p<.0001), trying to lose weight (p<.05), and self-esteem (p<.0001) significantly predicted regular smoking 1 year later. In the logistic regression model, perceived physical development (p<.05), and self-esteem (p<.001) significantly predicted regular smoking. The more developed a female reported being in comparison to other females her age, the more likely she was to be a regular smoker. Lower self-esteem was predictive of regular smoking. Perceived weight and trying to lose weight failed to reach statistical significance in the multivariate model. This current study highlights the importance of perceived physical development and self-esteem when predicting regular smoking in adolescent females. Efforts to promote positive self-esteem in young females may be an important strategy when creating interventions to reduce regular cigarette smoking. PMID:18686177

    Rodent models provide valuable insight into mechanisms that underlie vulnerability to adverse effects of early-life challenges. Few studies have evaluated sex differences in anxiogenic or depressogenic effects of adolescent social stress in a rodent model. Furthermore, adolescent stress studies often use genetically heterogeneous outbred rodents which can lead to variable results. The current study evaluated the effects of adolescent social stress in male and female inbred (BALB/cJ) mice. Adolescent mice were exposed to repeat cycles of alternating social isolation and social novelty for 4 weeks. Adolescent social stress increased anxiety-related behaviors in both sexes and depression-related behavior in females. Locomotion/exploratory behavior was also decreased in both sexes by stress. Previously stressed adult mice produced less basal fecal corticosteroids than controls. Overall, the novel protocol induced sex-specific changes in anxiety- and depression-related behaviors and corticoid production in inbred mice. The chronic variable social stress protocol used here may be beneficial to systematically investigate sex-specific neurobiological mechanisms underlying adolescent stress vulnerability where genetic background can be controlled. © 2017 Wiley Periodicals, Inc.

We investigated 307 students between 12 and 17 years old from six private schools, in the months March to June 2007. We applied a form which recorded sedentarism, BMI, blood pressure and blood glucose. The chi-squared test was used for to analysis the proportions. About 68% of young people were sedentary. The sedentarism was higher in females surveyed (p=0, 000) and those with over-weight (p=0,001). Among adolescents active exercise was the most practiced football (42%) and weights (19%). The health education in schools can assist in combating the sedentarism of the adolescents.

    Previous studies report varying rates of time-loss injuries in adolescent female soccer, ranging from 2.4 to 5.3 per 1000 athlete-exposures or 2.5 to 3.7 per 1000 hours of exposure. However, these studies collected data using traditional injury reports from coaches or medical staff, with methods that significantly underestimate injury rates compared with players' self-reports. The primary aim was to investigate the injury incidence in adolescent female soccer using self-reports via mobile telephone text messaging. The secondary aim was to explore the association between soccer exposure, playing level, and injury risk. Descriptive epidemiology study and cohort study; Level of evidence, 2 and 3. During a full adolescent female soccer season in Denmark (February-June 2012), a population-based sample of 498 girls aged 15 to 18 years was included in the prospective registration of injuries. All players were enrolled on a team participating in Danish Football Association series. Soccer injuries and exposure were reported weekly by answers to standardized text message questions, followed by individual injury interviews. Soccer exposure and playing levels were chosen a priori as the only independent variables of interest in the risk factor analyses. Injury rates and relative risks were estimated using Poisson regression. Generalized estimation equations were used to take into account that players were clustered within teams. There were 498 players who sustained a total of 424 soccer injuries. The incidence of injuries was 15.3 (95% CI, 13.1-17.8), the incidence of time-loss injuries was 9.7 (95% CI, 8.2-11.4), and the incidence of severe injuries was 1.1 (95% CI, 0.7-1.6) per 1000 hours of soccer exposure. Higher average exposure in injury-free weeks was associated with a lower injury risk (P value for trend <.001), and players with low exposure (≤1 h/wk) were 3 to 10 times more likely to sustain a time-loss injury compared with other players (P < .01). Playing level was

    Knee injuries are common in adolescent female football. Self-reported previous knee injury and low Knee injury and Osteoarthritis Outcome Score (KOOS) are proposed to predict future knee injuries, but evidence regarding this in adolescent female football is scarce. The aim of this study was to investigate self-reported previous knee injury and low KOOS subscale score as risk factors for future knee injuries in adolescent female football. A sample of 326 adolescent female football players, aged 15-18, without knee injury at baseline, were included. Data on self-reported previous knee injury and KOOS questionnaires were collected at baseline. Time-loss knee injuries and football exposures were reported weekly by answers to standardized text-message questions, followed by injury telephone interviews. A priori, self-reported previous knee injury and low KOOS subscale scores (< 80 points) were chosen as independent variables in the risk factor analyses. The study showed that self-reported previous knee injury significantly increased the risk of time-loss knee injury [relative risk (RR): 3.65, 95% confidence (CI) 1.73-7.68; P < 0.001]. Risk of time-loss knee injury was also significantly increased in players with low KOOS subscale scores (< 80 points) in Activities of Daily Living (RR: 5.0), Sport/Recreational (RR: 2.2) and Quality of Life (RR: 3.0) (P < 0.05). In conclusion, self-reported previous knee injury and low scores in three KOOS subscales significantly increase the risk of future time-loss knee injury in adolescent female football. © 2015 John Wiley & Sons A/S.

    Many adolescents are not physically active enough to receive associated health benefits. Furthermore, participation in physical activity generally declines during adolescence, and to a greater degree for females. Longitudinal research is required to better understand the determinants of change in physical activity by adolescent females to inform physical activity-related policy and practice. This study explored patterns of change in socioecological factors hypothesised to be associated with physical activity and sport, across the adolescent period for females. This longitudinal study employed three annual surveys of females from metropolitan and non-metropolitan areas recruited in Year 7 (n = 328) and Year 11 (n = 112). Self-report measures included questions regarding general barriers to participation, as well as factors relating to the socioecological domains. The barriers where significant changes within or differences between cohorts were observed were mostly intrapersonal (lack of energy, lack of time due to other leisure activities). Lack of time was more prevalent in the Year 11 cohort than in the Year 7 cohort. Perceived importance of life priorities mainly related to education and study and more so for the Year 11 cohort. Perceived competence declined for the Year 7 cohort. Support from family and peers trended downwards in both cohorts, whereas access to facilities increased both within and between cohorts. Significant patterns of change in the determinants of physical activity participation were observed across the adolescent period. It is important to consider flexible structure and scheduling of physical activity and strategies to develop competency in childhood and early adolescence. Copyright © 2014 Sports Medicine Australia.

    To examine the prevalence of unhealthy behaviors among a cohort of Vietnamese adolescents in California; to examine the relationship between these behaviors and school-related variables (school performance, educational risk behaviors, higher-education aspirations, and participation in extracurricular activities); and to assess the differences that may exist between males and females with regard to these factors. We conducted telephone interviews with 783 Vietnamese adolescents, aged 12-17 years, recruited through telephone listings from four California counties where large Vietnamese populations reside: San Francisco, Santa Clara, Los Angeles, and Orange. Of the 783 completed interviews, 60.8% were conducted in English and 39.2% in Vietnamese. The main outcome measure is a health risk behavior scale that includes adolescents' reports of ever smoking a cigarette, sedentary vs. active lifestyle, consumption of fruits and vegetables, consumption of foods high in fat, ever drinking alcohol, and ever engaging in sexual behavior. Multiple regression analyses were employed to estimate the association among the demographic variables, acculturation, school performance, aspirations, extracurricular activities, and the overall health risk. Females were significantly more sedentary than males. Over one-quarter (29%) of the females reported not having participated in vigorous physical activity on 3 or more days per week, compared with just 18% of the males. Most adolescents reported they had never tried cigarettes (84%), never used alcohol (77%), and never had sex (97%). Males were more likely than females to report a higher frequency of experimentation with smoking and drinking. Overall, school performance and participation in extracurricular activities were significantly related to the health risk behavior scale. Adolescents who demonstrated at least one educational risk (ever skipped school or ever sent out of the classroom) were more likely to engage in other risky

    To determine the prevalence of substance use in adolescents with eating disorders, compare the results with a data set of Ontario high school students, and explore why adolescents with eating disorders do, or do not, use various substances. From January 1999 to March 2000, 101 female adolescents who met the DSM-IV criteria for an eating disorder were followed up in a tertiary care pediatric treatment center. They were asked to participate in a cross-sectional study using a self-administered questionnaire assessing substance use and investigating reasons for use and nonuse; 95 agreed to participate and 77 completed the questionnaire (mean age, 15.2 years). The patients were divided into two groups: 63 with restrictive symptoms only, 17 with purging symptoms. The rates of drug use between subjects and their comparison groups were compared by z-scores, with the level of significance set at.05. During the preceding year, restrictors used significantly less tobacco, alcohol, and cannabis than grade- and sex-matched comparison populations, and purgers used these substances at rates similar to those of comparison subjects. Other drugs seen frequently in the purgers included hallucinogens, tranquilizers, stimulants, LSD, PCP, cocaine, and "ecstasy." Both groups used caffeine and laxatives, but few used diet pills. Restrictors said they did not use substances because they were bad for their health, tasted unpleasant, were contrary to their beliefs, and were too expensive. Purgers generally used substances to relax, relieve anger, avoid eating, and "get away" from problems. Female adolescents with eating disorders who have restrictive symptoms use substances less frequently than the general adolescent population but do not abstain from their use. Those with purging symptoms use substances with a similar frequency to that found in the general adolescent population. Because the sample size for the purging group was small, firm conclusions cannot be drawn from our analysis

Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia. This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401) and females (1507) aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use), physical activity using a validated questionnaire and dietary habits. A very high proportion (84% for males and 91.2% for females) of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p < 0.05) more sedentary, much less physically active, especially with vigorous physical activity, and there were fewer days per week when they consumed breakfast, fruit, milk and diary products, sugar-sweetened drinks, fast foods and energy drinks than did males. However, the females' intake of French fries and potato chips, cakes and donuts, and candy and chocolate was significantly (p < 0.05) higher than the males'.

    To examine the association between observer ratings of physical attractiveness and weight preoccupation for female adolescents, and to explore any ethnic differences between Caucasian, African-American, and Hispanic females. Normal-weight female adolescents who had participated in the National Longitudinal Study of Adolescent Health in-home Wave II survey were included (n = 4,324). Physical attractiveness ratings were made in vivo by interviewers. Using logistic regression models stratified by ethnicity, the associations between observer-rated attractiveness and weight preoccupation were examined after controlling for demographics, measured body mass index (BMI) and psychosocial factors. Caucasian female adolescents perceived as being more attractive reported significantly greater weight preoccupation compared with those rated as being less attractive. Observed attractiveness did not relate to weight preoccupation among African-American or Hispanic youth when controlling for other factors. For Caucasian female adolescents, being perceived by others as more attractive may be a risk factor for disordered eating.

    Six female adolescents participated in open-ended interviews regarding their experiences of depression. The transcripts of their interviews were explored using Interpretative Phenomenological Analysis (Smith, 1991). The analysis revealed three inter-connected super-ordinate themes which were: communication, hurt self, and difference. These themes centred on communication processes in participants' families and with peers, issues relating to shifts in identity through adolescence, and feelings of being damaged, distressed, and hurt. Amongst a range of potentially relevant perspectives, an attachment theory (Bowlby, 1969) orientation was found to be particularly relevant and helpful in interpreting the themes that captured these young women's experiences. Some implications for clinical practice are discussed.

  19. Adolescent activity-based anorexia increases anxiety-like behavior in adulthood.

    2010-09-01

    Activity-based anorexia is a paradigm that induces increased physical activity, reduced food intake, and heightened activity of the hypothalamic-pituitary-adrenal axis in adult rats. To investigate whether experience with activity-based anorexia produced enduring effects on brain and behavior, female adolescent rats experienced activity-based anorexia during adolescence and were tested in adulthood for anxiety-like behavior on an elevated plus maze and in an open field. Analysis of elevated plus maze and open field behavior in adulthood revealed that rats that experienced activity-based anorexia during adolescence, but not rats that were simply food restricted, displayed increased anxiety-like behavior in adulthood. Plasma corticosterone and expression levels of corticotropin-releasing hormone mRNA in the hypothalamic paraventricular nucleus and in the central nucleus of the amygdala were significantly elevated in adult rats that had undergone activity-based anorexia in adolescence in response to the open field exposure, as compared to control rats. These data demonstrate enduring effects of adolescent activity-based anorexia on anxiety-like behavior and neuroendocrine factors critical in stress responsivity in adulthood. Furthermore, we demonstrate that activity-based anorexia during adolescence serves as a model whereby prolonged anxiety is induced, allowing for evaluation of the behavioral and neural correlates of mediating anxiety-like behaviors in adulthood.

    This study compared perceptions of adolescents' friendships between adolescents with an autism spectrum disorder (ASD) and their parents, examined factors associated with friendship qualities, and investigated the adolescents' reports on the activities they did with friends and how activity patterns differed by gender. Ninety-one adolescents with an ASD and their parents completed mail-based surveys during the summer months. Adolescents with an ASD identified more friends than did their parents, but they agreed on the friends' characteristics. About half of the adolescents spent an average of 4 hours per day with friends during the summer months. Male adolescents with an ASD most frequently played video games with friends, whereas females most frequently had conversations with friends. The findings suggest that adolescents with an ASD and their parents identify different peers as the adolescent's friends. The findings also reveal similarities and differences in friendships between adolescents with an ASD and typically developing adolescents.

    Researchers have given significant attention to abstinence among adolescents, but far less is known about purposeful avoidance of sexual activity (and relationship involvement). Typically, it is assumed that, once adolescents have initiated sexual activity, they will thereafter engage in sexual activity if given the opportunity. However, it is unclear whether that is true as some research indicates that many adolescents engage in sexual activity intermittently. Sexually experienced adolescents may purposefully avoid engaging in sexual activity for a period of time and, if so, this has implications for understanding their sexual decision-making. We used a mixed methods approach to investigate sexually experienced adolescents' decisions to purposefully avoid further sexual activity and/or romantic relationships with a focus on how common these decisions are and factors influencing them. Participants were 411 (56 % female) adolescents (16-21 years old) who completed an on-line survey that assessed reasons for each type of avoidance, religiosity, sexual esteem, sexual distress, sexual coercion, and dysfunctional sexual beliefs. Overall, 27 % of participants had engaged in sexual avoidance and 47 % had engaged in romantic avoidance. Significantly more female than male adolescents reported sexual and romantic avoidance. Adolescents' reasons for sexual avoidance included: lack of sexual pleasure or enjoyment, relationship reasons, negative emotions, values, fear of negative outcomes, negative physical experience, and other priorities. Reasons for romantic avoidance included: effects of previous relationship, not interested in commitment, wrong time, other priorities, negative emotions, no one was good enough, and sexual concerns. Logistical regressions were used to assess associations between age, religiosity, sexual esteem, sexual distress, experience of sexual coercion, and dysfunctional sexual beliefs and having engaged in romantic and/or sexual avoidance.

    The physical health detriments associated with adolescent females' having older romantic partners are well documented. However, little is known about the relationship between having an older partner and females' subsequent mental health. Two waves of data from 1,440 participants in the National Longitudinal Study of Adolescent Health were analyzed. The sample was restricted to females in grades 7-12 who had not had sex at Wave 1 (1994-1995) and reported at least one romantic relationship by Wave 2 (1996). A lagged dependent variable approach with ordinary least-squares regression measured changes in depression and self-esteem associated with sexual and nonsexual relationships with same-age and older partners. Intimate partner violence was tested as a mediator. Compared with respondents reporting a nonsexual relationship with a same-age partner, those reporting a nonsexual relationship with an older partner, sex with a same-age partner or sex with an older partner experienced greater increases in depression between surveys; mean predicted depression levels at Wave 2 ranged from 7.7 to 9.0 across these groups (possible range, 0-27). Intimate partner violence explained one-third of the difference between those who had had sex and those who had not had sex with same-age partners. Fewer associations were found for self-esteem, and differences between groups were small. Health correlates of adolescent sexual behavior go beyond physical health outcomes. Future research should identify mechanisms through which relationships, especially those with older partners, are associated with declines in mental health.

    This study aims to investigate whether experiences of offline sexual coercion are associated with adolescent females' involvement in different types of sexting behaviors. It draws on data from 450 ethnically diverse female adolescents with an average age of 19.02 years (SD = 0.74) who were originally recruited in southeast Texas. The participants were asked about their experiences with sexual coercion, and their engagement in sexting behavior (i.e., sending, requesting, and being asked for a sext, and receiving a sext without giving permission). Logistic regressions were used to analyze these relationships, while controlling for age, ethnicity, education level, living situation, and sexting behaviors in the year prior of the study. Offline sexual coercion was significantly associated with sending and being asked for a naked image, as well as receiving a naked image without giving permission. The results suggest that sexting could function as an online extension of offline forms of sexual coercion. Copyright © 2016 The Foundation for Professionals in Services for Adolescents.

    Female athletes are 2 to 8 times more likely than male athletes to injure the anterior cruciate ligament during a non-contact athletic maneuver. Identifying anterior cruciate ligament injury risk factors in female athletes may help with the development of preventive training programs aimed at reducing injury rates. Differences between genders in lower limb kinematics, kinetics, and neuromuscular patterns will be identified in an adolescent soccer population during an unanticipated side-cut maneuver. Controlled laboratory study. Forty-two elite adolescent soccer players (21 male and 21 female) performed an unanticipated side-cut maneuver, with the 3-dimensional kinematic, kinetic, and electromyographic lower limb data being analyzed using principal component analysis. The female athletes had higher gastrocnemius activity, normalized to maximal voluntary isometric contractions, and a mediolateral gastrocnemius activation imbalance that was not present in the male athletes during early stance to midstance of the side-cut. Female athletes demonstrated greater rectus femoris muscle activity throughout stance, and the only hamstring difference identified was a mediolateral activation imbalance in male athletes only. Female athletes performed the side-cut with less hip flexion and more hip external rotation and also generated a smaller hip flexion moment compared with the male athletes. This is the first study to identify gender-related differences in gastrocnemius muscle activity during an unanticipated cutting maneuver. The increased and imbalanced gastrocnemius muscle activity, combined with increased rectus femoris muscle activity and reduced hip flexion angles and moments in female subjects, may all have important contributing roles in the higher noncontact ACL injury rates observed in female athletes.

    Background Few studies have investigated factors that influence physical activity behavior during the transition from adolescence to adulthood. This study explores the associations of sociodemographic, behavioral, sociocultural, attitudinal and physical factors measured in childhood and adolescence with physical activity behavior during the transition from adolescence to adulthood. Methods Childhood and adolescent data (at ages 7-15 years) were collected as part of the 1985 Australian Health and Fitness Survey and subdivided into sociodemographics (socioeconomic status, parental education), behavioral (smoking, alcohol, sports diversity, outside school sports), sociocultural (active father, active mother, any older siblings, any younger siblings, language spoken at home), attitudinal (sports/recreational competency, self-rated health, enjoyment physical education/physical activity, not enjoying school sports) and physical (BMI, time taken to run 1.6 km, long jump) factors. Physical activity between the ages 15 and 29 years was reported retrospectively using the Historical Leisure Activity Questionnaire at follow-up in 2004-2006 by 2,048 participants in the Childhood Determinants of Adult Health Study (CDAH). Australia's physical activity recommendations for children and adults were used to categorize participants as persistently active, variably active or persistently inactive during the transition from adolescence to adulthood. Results For females, perceived sports competency in childhood and adolescence was significantly associated with being persistently active (RR = 1.88, 95% CI = 1.39, 2.55). Smoking (RR = 0.31 CI = 0.12, 0.82) and having younger siblings (RR = 0.69 CI = 0.52, 0.93) were inversely associated with being persistently active after taking physical and attitudinal factors into account. For males, playing sport outside school (RR = 1.47 CI = 1.05, 2.08), having active fathers (RR = 1.25 CI = 1.01, 1.54) and not enjoying school sport (RR = 4.07 CI

    The association between sleep and the menstrual cycle in the adolescent population has been scarcely studied. This study aimed to investigate the association between sleep duration and menstrual cycle irregularity among female adolescents using nationwide representative data from the South Korean population. This population-based, cross-sectional study used the data collected from Korea National Health and Nutrition Examination Survey 2010-2012, and the data from 801 female adolescents were analyzed. Hierarchical multivariable logistic regression analysis was performed to assess the risk of menstrual cycle irregularity in relation to sleep duration. Subjects with menstrual cycle irregularity accounted for 15% (N = 120). The mean sleep duration in subjects with menstrual cycle irregularity was significantly shorter than that in those without (p = 0.003). Menstrual cycle irregularity prevalence tended to decrease as sleep duration increased (p for trend = 0.004), which was significantly different based on sleep duration and presence of depressive mood (p = 0.011). Sleep duration ≤5 h per day was significantly associated with increased risk of menstrual cycle irregularity compared with that in the subjects whose sleep duration is ≥8 h per day even after adjusting for confounding variables. The odds ratios of menstrual cycle irregularity tended to increase for shorter sleep duration in all adjusted models. This study found a significant inverse association between sleep duration and menstrual cycle irregularity among Korean female adolescents. Increasing sleep duration is required to improve the reproductive health of female adolescents. Copyright © 2017 Elsevier B.V. All rights reserved.

    This study tested a mediated effects model of psychological and behavioral adaptation to puberty within the context of physical activity (PA). Biological maturity status, physical self-concept, PA, and health-related quality of life (HRQoL) were assessed in 222 female British year 7 to 9 pupils (mean age = 12.7 years, SD = .8). Structural equation modeling using maximum likelihood estimation and bootstrapping procedures supported the hypothesized model. Maturation status was inversely related to perceptions of sport competence, body attractiveness, and physical condition; and indirectly and inversely related to physical self-worth, PA, and HRQoL. Examination of the bootstrap-generated bias-corrected confidence intervals representing the direct and indirect paths between suggested that physical self-concept partially mediated the relations between maturity status and PA, and maturity status and HRQoL. Evidence supports the contention that perceptions of the physical self partially mediate relations maturity, PA, and HRQoL in adolescent females.

    Context: Physical activity may affect the concentrations of circulating endogenous hormones in female athletes. Understanding the relationship between athletic and physical activity and circulating female hormone concentrations is critical. Objective: To test the hypotheses that (1) the estradiol-progesterone profile of high school adolescent girls participating in training, conditioning, and competition would differ from that of physically inactive, age-matched adolescent girls throughout a 3-month period; and (2) athletic training and conditioning would alter body composition (muscle, bone), leading to an increasingly greater lean–body-mass to fat–body-mass ratio with accompanying hormonal changes. Design: Cohort study. Settings: Laboratory and participants' homes. Patients or Other Participants: A total of 106 adolescent girls, ages 14–18 years, who had experienced at least 3 menstrual cycles in their lifetime. Main Outcome Measure(s): Participants were prospectively monitored throughout a 13-week period, with weekly physical activity assessments and 15 urine samples for estrogen, luteinizing hormone, creatinine, and progesterone concentrations. Each girl underwent body-composition measurements before and after the study period. Results: Seventy-four of the 98 girls (76%) who completed the study classified themselves as athletes. Body mass index, body mass, and fat measures remained stable, and 17 teenagers had no complete menstrual cycle during the observation period. Mean concentrations of log(estrogen/creatinine) were slightly greater in nonathletes who had cycles of <24 or >35 days. Mean log(progesterone/creatinine) concentrations in nonathletes were less in the first half and greater in the second half of the cycle, but the differences were not statistically significant. Conclusions: A moderate level of athletic or physical activity did not influence urine concentrations of estrogen, progesterone, or luteinizing hormones. However, none of the

    Purpose: This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia. Methods: We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model. Results: Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia. Conclusion: The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents’ risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

    This paper describes the nature and characteristics of the dating relationships of adolescent females, including any of their experiences of abuse. A grounded theory approach was used with 22 theoretically sampled female adolescents ages 15-18. Several important themes emerged: Seven stages of dating consistently described the relationships of female adolescents. A circle consisting of two interacting same sex peer groups provided structure for each teen as they navigated the dating course. The circle was the central factor affecting a female adolescent's potential for risk or harm in dating relationships. Teens defined abuse as an act where the intention is to hurt. Having once succumbed to sexual pressure, teens felt unable to refuse sex in subsequent situations. An awareness of both the stages of dating and the dynamics of the circle will assist health care providers to plan and implement interventions in the female adolescent population. Study findings on factors and influences that support non-abusive versus abusive relationship might help identify female teens at risk and/or support interventions aimed at preventing dating violence.

    Rates of adult women receiving contraceptive provision when simultaneously prescribed a known teratogen are alarmingly low. The prevalence of this behavior among pediatric providers and their adolescent patients is unknown. The objective of this study was to describe pediatric provider behaviors for prescribing teratogens concurrently with counseling, referral, and/or prescribing of contraception (collectively called contraceptive provision) in the adolescent population. A retrospective review was conducted examining visits in 2008-2012 by adolescents aged 14 to 25 years in which a known teratogen (US Food and Drug Administration pregnancy risk category D or X) was prescribed. The electronic medical records were queried for demographic information, evidence of contraceptive provision, and menstrual and sexual histories. The data were analyzed using standard statistical methods. Within 4172 clinic visits, 1694 females received 4506 prescriptions for teratogenic medications. The most commonly prescribed teratogens were topiramate, methotrexate, diazepam, isotretinoin, and enalapril. The subspecialties prescribing teratogens most frequently were neurology, hematology-oncology, and dermatology. Overall, contraceptive provision was documented in 28.6% of the visits. Whites versus nonwhites and older versus younger girls were more likely to receive contraceptive provision. The presence of a federal risk mitigation system for the teratogen also increased the likelihood of contraceptive provision. Our data demonstrate female adolescents prescribed teratogens receive inadequate contraception provision, which could increase their risk for negative pregnancy outcomes. Although the presence of a federal risk mitigation system appears to improve contraceptive provision, these systems are costly and, in some instances, difficult to implement. Efforts to improve provider practices are needed. Copyright © 2016 by the American Academy of Pediatrics.

    This study sought to determine whether perceiving portrayals of sexual stereotypes in rap music videos was associated with adverse health outcomes among African American adolescent females. African American female adolescents (n = 522) were recruited from community venues. Adolescents completed a survey consisting of questions on sociodemographic characteristics, rap music video viewing habits, and a scale that assessed the primary predictor variable, portrayal of sexual stereotypes in rap music videos. Adolescents also completed an interview that assessed the health outcomes and provided urine for a marijuana screen. In logistic regression analyses, adolescents who perceived more portrayals of sexual stereotypes in rap music videos were more likely to engage in binge drinking (OR 3.8, 95% CI 1.32-11.04, p = 0.01), test positive for marijuana (OR 3.4, 95% CI 1.19-9.85, p = 0.02), have multiple sexual partners (OR 1.9, 95% CI 1.01-3.71, p = 0.04), and have a negative body image (OR 1.5, 95% CI 1.02-2.26, p = 0.04). This is one of the first studies quantitatively examining the relationship between cultural images of sexual stereotypes in rap music videos and a spectrum of adverse health outcomes in African American female adolescents. Greater attention to this social issue may improve the health of all adolescent females.

    Rural female adolescents experience unique circumstances to sexual health care and information as compared to urban adolescents. These circumstances are largely due to their more isolated geographical location and rural sociocultural factors. These circumstances may be contributing factors to an incidence of adolescent pregnancy that is higher in rural areas than in urban cities. Thus, this higher incidence of pregnancy may be due to the ways in which rural adolescents make decisions regarding engagement in sexual intercourse. However, the rural female adolescent sexual decision-making process has rarely, if ever, been studied, and further investigation of this process is necessary. Focusing on rural female adolescents aged 16-19 years is especially significant as this age range is used for reporting most pregnancy and birth statistics in Ontario. Charmaz's guidelines for a constructivist grounded theory methodology were used to gain an in-depth understanding of eight Ontario rural female adolescents' decision-making process regarding sexual intercourse and pregnancy, and how they viewed rural factors and circumstances influencing this process. Research participants were obtained through initial sampling (from criteria developed prior to the study) and theoretical sampling (by collecting data that better inform the categories emerging from the data). Eight participants, aged 16-19 years, were invited to each take part in 1-2-hour individual interviews, and four of these participants were interviewed a second time to verify and elaborate on emerging constructed concepts, conceptual relationships, and the developing process. Data collection and analysis included both field notes and individual interviews in person and over the telephone. Data were analyzed for emerging themes to construct a theory to understand the participants' experiences making sexual decisions in a rural environment.

    A fourteen-year-old female shot-putter developed midfoot pain with activity that initially responded to nonoperative care. However, the symptoms subsequently returned and became persistent. Advanced imaging demonstrated a fibrous cuboid-navicular tarsal coalition. Surgical resection of the tarsal coalition was performed when the patient was seventeen years old, and she returned to sports activities postoperatively with no pain. Although fibrous cuboid-navicular tarsal coalition is a very rare condition, it should be considered as one cause of persistent midfoot pain in an adolescent athlete. Surgical resection of the tarsal coalition can lead to a resolution of symptoms.

    Over 15 million adolescents use the emergency department (ED) each year in the United States. Adolescent females who use the ED for medical care have been found to be at high risk for unintended pregnancy. Given that adolescents represent the largest users of text messaging and are receptive to receiving text messages related to their sexual health, the ED visit represents an opportunity for intervention. The aim of this qualitative study was to explore interest in and preferences for the content, frequency, and timing of an ED-based text message intervention to prevent pregnancy for adolescent females. We conducted semistructured, open-ended interviews in one urban ED in the United States with adolescent females aged 14-19 years. Eligible subjects were adolescents who were sexually active in the past 3 months, presented to the ED for a reproductive health complaint, owned a mobile phone, and did not use effective contraception.

All were interested in receiving text messages from the ED about pregnancy prevention, favoring messages that were "brief," "professional," and "nonaccusatory." Respondents favored texts with links to websites, repeated information regarding places to receive "confidential" care, and focused information on contraception options and misconceptions. Preferences for text message frequency varied from daily to monthly, with random hours of delivery to maintain "surprise." No participant feared that text

    Background Over 15 million adolescents use the emergency department (ED) each year in the United States. Adolescent females who use the ED for medical care have been found to be at high risk for unintended pregnancy. Given that adolescents represent the largest users of text messaging and are receptive to receiving text messages related to their sexual health, the ED visit represents an opportunity for intervention. Objective The aim of this qualitative study was to explore interest in and preferences for the content, frequency, and timing of an ED-based text message intervention to prevent pregnancy for adolescent females. Methods We conducted semistructured, open-ended interviews in one urban ED in the United States with adolescent females aged 14-19 years. Eligible subjects were adolescents who were sexually active in the past 3 months, presented to the ED for a reproductive health complaint, owned a mobile phone, and did not use effective contraception. Using an interview guide, enrollment continued until saturation of key themes. The investigators designed sample text messages using the Health Beliefs Model and participants viewed these on a mobile phone. The team recorded, transcribed, and coded interviews based on thematic analysis using the qualitative analysis software NVivo and Excel. Results Participants (n=14) were predominantly Hispanic (13/14; 93%), insured (13/14; 93%), ED users in the past year (12/14; 86%), and frequent text users (10/14; 71% had sent or received >30 texts per day).

    FTO rs9939609 variant has been shown to be associated with insulin resistance in Caucasian children. However, studies in Asia show inconsistent findings. We investigated the association between FTO rs9939609 polymorphisms and insulin resistance in obese female adolescents in Indonesia, a genetically distinct group within Asia. A total of 78 obese female adolescents participated in this study. The risk allele (A) frequency of FTO rs9939609 variant in Indonesian obese female adolescence was 44.2%. The frequency of insulin resistance was higher in the subjects with AA (54.6%) or AT (59.6%) than the subject with TT genotype (50%), but did not statistically different (p = 0.81 and p = 0.47, respectively). The insulin resistance rate was also higher in the risk allele (A) than the non-risk allele (T) subjects (0.58 vs. 0.55), but did not statistically different (p = 0.75). There was no association between FTO rs9939609 variant and body mass index, fasting glucose level, fasting insulin level, homeostatic model assessment of insulin resistance, and waist circumference (p > 0.05). In conclusion, FTO rs9939609 variant may not be associated with insulin resistance in Indonesian obese female adolescents. A multicenter study with a larger sample size is needed to clarify these findings.

    The high prevalence of obesity in the pediatric age groups draws attention to lifestyle factors including diet and physical activity. Data on obesity in adolescents and their snacking behavior are conflicting. This study aimed to assess the association of snacking behavior and obesity among female adolescents in Isfahan, Iran. This cross-sectional study was carried out on 265 female Isfahanian students who were chosen by systematic cluster random sampling. Dietary intake was assessed using a validated self-administered semiquantitative food frequency questionnaire that included 53 food items. Snacking behavior was defined by healthy snack score in combination with the frequency of snack intake. Individuals who consumed more healthy snacks and those with snacking frequency of 4 times a day or more had significantly lower weight, body mass index (BMI), and waist circumference (p < 0.001). Decreased consumption of healthy snacks was significantly associated with a greater chance of being overweight, generally obese, and abdominally obese among adolescents (odds ratio [OR] = 1.98; 95% confidence interval [CI], 1.00-3.14, ptrend = 0.04 and OR = 2.10; 95% CI, 1.01-3.13, ptrend = 0.04, respectively). Frequency of snack intake was inversely related to overweight, general obesity, and abdominal obesity (OR = 3.23; 95% CI, 1.73-5.61, ptrend = 0.03 and OR = 1.84; 95% CI, 1.05-3.20, ptrend = 0.04, respectively). Healthy snack score in combination with frequency of snacking showed that those in the lowest tertile of snacking who consumed snacks less than 4 times/day had the highest risk of obesity compared to other categories (OR = 2.09, 95% CI, 1.11-3.20, p < 0.001). More frequent consumption of healthy snacks is associated with decreased prevalence of overweight, general obesity, and abdominal obesity in adolescents. Further studies, in particular of a prospective nature, are required to examine this association in other populations.

    To analyze the association between physical activity and social support from parents and friends on the physical activity level among adolescents. Data from 2,361 adolescents (56.6% females; mean age 16.4; SD = 1.2), from public and private high schools were analyzed. The physical activity level of the adolescents, parents, and friends were measured through a questionnaire. Parents' and friends' support and self-efficacy were measured using two previously tested scales. Data analysis was performed using the structural equation modeling in IBM® SPSS® Amos™ 20.0. Physical activity of friends was directly associated with physical activity level of adolescents. Physical activity of the father was associated with that of their sons, and the physical activity of mother was associated with that of their daughters. An indirect association was identified between the physical activity of parents and friends with physical activity level of the adolescents, mediated by social support. Social support was directly associated with physical activity in adolescents of both genders and indirectly mediated by self-efficacy. Parents and friends have a social influence on adolescents' level of physical activity through the mechanism of behavior modeling or through social support, mediated by self-efficacy.

    Peer-interactions are particularly important during adolescence and teenagers display enhanced sensitivity toward rejection by peers. Social rejection has been shown to induce alterations in pain perception in humans. However, the neurobiological consequences of adolescent social rejection have yet to be extensively characterized, and no appropriate animal model is available. Here, we propose inadequate playful interactions in adolescent rats as a novel animal model for social peer-rejection and examine potential long-term consequences into adulthood. Acute social pairing of female adolescent Wistar rats with an age-matched rat from the less playful Fischer344 strain was found to alter social play and decrease pain reactivity, indicating Fischer rats as inadequate social partners for Wistar animals. Therefore, in a second experiment, adolescent female Wistar rats were either reared with another Wistar rat (adequate social rearing; control) or with a Fischer rat (inadequate social rearing; play-deprived). Beginning on day 50, all Wistar rats were group housed with same-strain partners and tested for behavioral, neurobiological and endocrine differences in adulthood. Playful peer-interactions were decreased during adolescence in play-deprived animals, without affecting social contact behavior. Consequently, adult play-deprived rats showed decreased pain sensitivity and increased startle reactivity compared to controls, but did not differ in activity, anxiety-related behavior or social interaction. Both groups also differed in their endocrine stress-response, and expression levels of the cannabinoid CB1 receptor were increased in the thalamus, whereas FAAH levels were decreased in the amygdala. The present animal model therefore represents a novel approach to assess the long-term consequences of peer-rejection during adolescence. Copyright © 2013 Elsevier B.V. and ECNP.

    2011-01-01

    Background Physical inactivity is related to many morbidities but the evidence of its link with depression in adolescents needs further investigation in view of the existing conflicting reports. Methods The data for this cross-sectional study were collected from 1,100 Nigerian adolescents aged 12-17 years. Depressive symptomatology and physical activity were assessed using the Children's Depression Inventory (CDI) and the Physical Activity Questionnaire-Adolescent version (PAQ-A) respectively. Independent t tests, Pearson's Moment Correlation and Multi-level logistic regression analyses for individual and school area influences were carried out on the data at p < 0.05. Results The mean age of the participants was 15.20 ± 1.435 years. The prevalence of mild to moderate depression was 23.8%, definite depression was 5.7% and low physical activity was 53.8%. More severe depressive symptoms were linked with lower levels of physical activity (r = -0.82, p < 0.001) and moderate physical activity was linked with reduced risk of depressive symptoms (OR = 0.42, 95% CI = 0.29-0.71). The odds of having depressive symptoms were higher in older adolescents (OR = 2.16, 95% CI = 1.81-3.44) and in females (OR = 2.92, 95% CI = 1.82-3.54). Females had a higher risk of low physical activity than male adolescents (OR = 2.91, 95% CI = 1.51-4.26). Being in Senior Secondary class three was a significant predictor of depressive symptoms (OR = 3.4, 95% CI = 2.55-4.37) and low physical activity. Conclusions A sizable burden of depression and low physical activity existed among the studied adolescents and these were linked to both individual and school factors. Future studies should examine the effects of physical activity among clinical samples of adolescents with depression. PMID:21569581

    Adolescent smoking relates to numerous risk factors, of which beliefs and attitudes toward smoking may play a role. The study aimed to investigate the association between beliefs and attitudes and the risk of adolescent smoking. In a school-based cross-sectional study, 3,400 students were recruited from 34 intermediate and secondary schools in Madinah City, Al Madinah Region, Saudi Arabia. Data about sociodemographics, smoking-related factors, and beliefs and attitudes toward smoking were collected using a valid and reliable self-administered questionnaire. Prevalence of smoking was estimated and the studied beliefs and attitudes were compared by smoking status and sex using appropriate statistical analyses including multivariate logistic regression. Of the 3,322 respondents, 33.02% (38.9% males and 26.4% females) were current smokers. Beliefs and attitudes toward smoking significantly differed between smokers and nonsmokers in the studied male and female students. The adjusted risk of smoking was significantly increased among female adolescents who believed that male smokers were more attractive [odds ratio (OR) = 2.2; 95% confidence interval (CI) = 1.6-2.9] and among male smokers who believed that female smokers are more attractive (OR = 1.7; 95% CI = 1.2-2.2). The risk was also increased among all adolescents who believed that smoking lent comfort in social gatherings. Belief that smoking is harmful, however, was negatively associated with the risk of smoking, particularly among females (OR = 0.55; 95% CI = 0.35-0.91). The study revealed a considerable high prevalence of smoking among male and female adolescents. Addressing the beliefs and knowledge about smoking during childhood is crucial in any antismoking program.

    The rising prevalence of non-communicable diseases (NCDs) has become a serious public health issue. Among the multi-factorial drivers behind NCDs are modifiable health risk factors, most notably, physical inactivity. In response to the nearly global policy priority of encouraging regular participation in physical activity, the objective of the present study is to examine the factors that determine participation in physical activity among Malaysian adolescents. Nationally representative data consisting of a large sample size was used. A censored regression model was developed to estimate the likelihood of participation and time spent on physical activity. There are significant relationships between physical activity and gender, ethnicity, self-rated academic performance, maternal education, household size and time spent on physical education. The present study provides new insights into the factors affecting physical activity participation among adolescents. Specifically, self-rated excellent academic performance, household size and physical education can increase the likelihood of being physically active. Evidence of the present study implies that policy makers should pay special attention to females, Chinese, adolescents with self-rated poor academic performance and adolescents who have low maternal education.

    The article features a brief overview of theoretical and empirical studies in communication psychology and sociability of men and women, boys and girls. Russian and foreign studies are summarized to point out that girls and women place greater emphasis on communication and interpersonal relations than do boys and men. Moreover, female communication is more emotional. The article presents the results of the author's own empirical study of male and female communicative activity. Communicative activity is viewed as a complex psychological phenomenon, a degree of the subject's willingness to interact. Communicative activity was studied with the test proposed by the Russian psychologist, Krupnov, and designed to detect the following components of communicative activity: dynamic (natural), emotional, motivational, cognitive, regulatory, productive, and two sorts of communication difficulties (operational and personal). Gender differences in communicative activity are shown on a sample of 480 participants aged 18-40 (240 men and 240 women). The article then describes communicative styles of adolescents (130 boys and 130 girls, aged 19-24). Various communicative styles are featured, including "energetic, businesslike," "conformal, emotional," "diplomatic, externally oriented" for boys and "energetic, sociable," "emotional, difficult," and "complaisant, expressive" for girls. Every person's individuality and gender identity are shown to impact their communicative style.

    Given the increasing prevalence of obesity among Iranian adolescents and the role of consumption of unhealthy snacks in this issue, interventions that focus on factors influencing food choice are needed. This study was designed to delineate factors associated with unhealthy snack use among female Iranian adolescents. The theory of Planned Behavior served as the framework of the study. Qualitative data were collected via nine focus group discussions in two middle schools (6(th) to 8(th) grades) in a socio-economically diverse district in the city of Tehran in spring 2008. The study sample included 90 female adolescents aged 12-15 years. The sampling strategy was purposive method. Data analyzed using the "framework" method. Major factors identified by the respondents were taste, peer pressure, parental influence, easy access to unhealthy snacks, limited availability of healthy snacks, appeal of snacks, habit, high price of healthy snacks, and media advertisements. Nutritional value and healthiness was not one of the first priorities when buying snacks, as adolescents thought it was too early for them to worry about illness and adverse consequences of eating junk foods. For developing culturally sensitive evidence-based interventions that can motivate adolescents to choose healthy snacks, a broad range of factors should be taken into account.

    Based on Harter's (12,13) competence motivation theory, this study examined the relationship of coaches' performance feedback and motivational climate with female athletes' perceived competence, enjoyment, and intrinsic motivation. Female adolescent soccer players (N = 141) completed measures of relevant constructs toward the latter part of their season. Canonical correlation analysis revealed that athletes' perceptions of greater positive and informational feedback given by coaches in response to successful performance attempts, greater emphasis placed on a mastery climate, and less emphasis placed on a performance climate, were significantly related to greater ability perceptions, enjoyment, and intrinsic motivation. Exploratory analyses also showed that the relationship between feedback and the psychosocial outcomes may vary as a function of the perceived motivational climate. Overall, these results suggest that coaching feedback and motivational climate are important contributors to explaining adolescent females' continued motivation to participate in sport.

    Notter, Kathryn Betz

    of role models, the need for parental support, social stigmatisms and peer pressure are still major factors that determine whether adolescent females seek out STEM activities. An interesting finding, which was an exception to previous findings, was these female adolescents enjoyed the challenge of the competition. The informal learning environments encouraged an atmosphere of social engagement and cooperative learning. Many volunteers that led the afterschool programs were women (role models) and a majority of parents showed support by accommodating an afterschool situation. The young women that were engaged in the competition noted it was a friendly competition, but they were all there to win. All who participated in the competition had a similar learning environment: competitive but cooperative. Further research is needed to determine if it is the learning environment that lures adolescent females to the program and entices them to continue in the STEM fields or if it is the competitive aspect of the culminating activity.

    Theories of Erikson and Marcia were applied to assess the relation between identity status and academic achievement in female adolescents. The differences in identity status between bright high achieving vs. underachieving students were ascertained separately for occupational planning, attitudes toward religion, and peer relations. It was hypothesized that the component of identity most closely linked to high achievement in school is having made commitments to certain goals and values. It was found instead that experiencing and working through crises in beliefs and values are more closely associated with successful academic achievement and formation of identity among adolescent girls than having made specific commitments to career or ideology.

    This study used a person-centered approach to examine patterns of adjustment along psychological (i.e., depression, self-esteem, anxiety) and academic (i.e., academic motivation) domains in a sample (N = 338) of Mexican-origin female adolescents. Four adjustment profiles were identified. A High Functioning (n = 173) group, which exhibited high positive adjustment and academic functioning, an Average Functioning (n = 83) group, who exhibited average psychological and academic functioning, an Academically Oriented and Stressed (n = 19) group, who exhibited high academic motivation, but poor psychological functioning in anxiety and negative affect, and a Low Functioning” (n = 25) group, who exhibited poor adjustment overall. Further, paternal and maternal parenting characteristics (i.e., autonomy granting, parent-adolescent conflict, and supportive parenting) were differentially related to Mexican-origin female adolescents’ profiles, providing further evidence for the existence of the profiles. Results contribute to the current literature on Latino adolescents and highlight the importance of examining psychological and academic domains concurrently to determine how these two domains of adjustment are linked among this population.

    African-American adolescent females are at high risk for HIV infection, acquired primarily as a result of heterosexual intercourse. Multiple regression analyses was used to describe the correlates of the outcome variable, ever having had sex, for low-income African-American adolescent females in a cross-sectional study of 322 (N = 322) mother/daughter pairs. The results revealed that while the daughters' age was positively associated with the outcome variable, the daughters' perceptions of strictness of curfew and maternal monitoring, and the daughters'self-efficacy to refuse sex and their intention to refuse sex were negatively associated with the outcome variable. Mothers tended to report significantly more maternal monitoring and stricter curfews than what their daughters perceived them to be. The daughters'intention to refuse sex mediated the effects of age and self-efficacy to refuse sex on the outcome variable. These results suggest that health-care providers should promote clearer communication between mothers and daughters in order to reduce divergent perceptions and to help mothers facilitate their daughters' self-efficacy and their intention to refuse sex.

    Objective To explore age differences in factors associated with positive sexually transmitted diseases (STD) status among a sample of African-American adolescent females. Methods Data were collected via ACASI from 701 African-American adolescent females (14–20 years) seeking services at reproductive health clinics. Adolescents provided self-collected vaginal swabs assayed using NAAT to assess the prevalence of three STDs. Results Younger adolescents (14–17 years) had significantly higher rates of STDs than older adolescents (18–20 years), but older adolescents had significantly higher levels of STD-associated risk behavior. In controlled analysis, having a casual sex partner was the only variable significantly associated with a positive STD test for younger adolescents, and prior history of STD and higher impulsivity were significantly associated with testing STD positive among older adolescents. Conclusions These findings suggest that developmentally tailored STD/HIV prevention interventions are needed for younger and older subgroups of adolescent females to help reduce their risk of infection.

    Structural neuroimaging studies have demonstrated lower regional gray matter volume in adolescents with severe substance and conduct problems. These research studies, including ours, have generally focused on male-only or mixed-sex samples of adolescents with conduct and/or substance problems. Here we compare gray matter volume between female adolescents with severe substance and conduct problems and female healthy controls of similar ages. Female adolescents with severe substance and conduct problems will show significantly less gray matter volume in frontal regions critical to inhibition (i.e. dorsolateral prefrontal cortex and ventrolateral prefrontal cortex), conflict processing (i.e., anterior cingulate), valuation of expected outcomes (i.e., medial orbitofrontal cortex) and the dopamine reward system (i.e. striatum). We conducted whole-brain voxel-based morphometric comparison of structural MR images of 22 patients (14-18 years) with severe substance and conduct problems and 21 controls of similar age using statistical parametric mapping (SPM) and voxel-based morphometric (VBM8) toolbox. We tested group differences in regional gray matter volume with analyses of covariance, adjusting for age and IQ at p<0.05, corrected for multiple comparisons at whole-brain cluster-level threshold. Female adolescents with severe substance and conduct problems compared to controls showed significantly less gray matter volume in right dorsolateral prefrontal cortex, left ventrolateral prefrontal cortex, medial orbitofrontal cortex, anterior cingulate, bilateral somatosensory cortex, left supramarginal gyrus, and bilateral angular gyrus. Considering the entire brain, patients had 9.5% less overall gray matter volume compared to controls. Female adolescents with severe substance and conduct problems in comparison to similarly aged female healthy controls showed substantially lower gray matter volume in brain regions involved in inhibition, conflict processing, valuation of

    The aim of the study was to evaluate the influence of hirsutism on general quality of life, self-esteem and the prevalence of anxiety and depressive symptoms among adolescent girls. Fifty adolescent females with hirsutism, aged 13-18 years, were enrolled in the research group. The control group comprised 50 non-hirsute adolescents. A specific questionnaire was used as the research tool. It included self-evaluation inventories: Short Form-36 Health Survey Version 2, Hospital Anxiety and Depression Scale and Rosenberg Self-Esteem Scale. Quality of life indices for hirsute girls scored lower than for the controls and statistically significantly so with regard to physical functioning (p = 0.04), general health (p = 0.002) and social functioning (p = 0.007). Anxiety was diagnosed in 26% in the group of hirsute girls as compared with 10% of the controls (p = 0.03). The study analysis revealed more clinically significant problems of low self-esteem in hirsute adolescents compared with non-hirsute girls (14% vs. 2%). Hirsutism is associated with a decreased quality of life, a higher prevalence of anxiety disorder and lower self-esteem in adolescent females. The mother's level of education is associated with the quality of life in adolescent girls.

    Objective: To evaluate the relationship between the stages of somatic maturation and body composition in eutrophic female adolescents with or without excessive body fat. Methods: Cross-sectional study of 118 female adolescents, from 14 to 19 years-old, in Viçosa, Minas Gerais, Southeast Brazil. The adolescents were divided in two groups: Group 1 (G1), eutrophic with adequate body fat percentage, and Group 2 (G2), eutrophic with high body fat percentage. The somatic maturation was assessed by the formula for estimating the Peak Height Velocity (PHV). Results: The PHV had higher average score in G1 adolescents compared to G2 (0.26 versus 0.05; p=0.032). There was an association between G1, G2 and the somatic maturation (p=0.049). The female adolescents before and during PHV presented higher values of fat body BMI (p=0.034) and percentage of central fat (p=0.039) compared to the adolescents after PHV. There was a correspondence between before PHV stage and the excess of body fat (α=0.751). Conclusions: There was an association between somatic maturation and body composition in eutrophic female adolescents. Length, BMI and fat percentage were different among the somatic maturation stages. It is relevant to evaluate the somatic maturation and the changes occurring in the body composition during adolescence in order to better evaluate and manage the nutritional status and the body fat excess.

Through the last decades much attention has been directed toward various anatomical and biomechanical risk factors for non-contact ACL injury, and important information have been retrieved about the influence of external loading factors on ACL injury risk during given sports-specific movements. However, much less attention has been given to the aspect of neuromuscular control during such movements and only sparse knowledge exists on the specific muscle activation patterns involved during specific risk conditions. Therefore, the aim of this narrative review was (1) to describe anatomical aspects, strength aspects and biomechanical aspects relevant for the understanding of ACL non-contact injury mechanisms in young female athletes, and (2) to review the existing literature on lower limb muscle activation in relation to risk of non-contact ACL-injury and prevention of ACL injury in young female athletes. Studies investigating muscle activity patterns associated with sports-specific risk situations were identified, comprising cohort studies, intervention studies and prospective studies. Based on the retrieved studies, clear gender-specific differences in muscle activation and coordination were identified demonstrating elevated quadriceps activity and reduced hamstring activity in young female athletes compared to their male counterparts, and suggesting young female athletes to be at elevated risk of non-contact ACL injury. Only few studies ( n = 6) examined the effect of preventive exercise-based intervention protocols on lower limb muscle activation during sports-specific movements. A general trend toward enhanced hamstring activation was observed during selected injury risk situations (e.g., sidecutting and drop landings). Only a single study examined the association between muscle activation deficits and ACL injury risk

    Estimating whether adolescents' sedentary behaviour and their lack of physical activity is determined by family characteristics or socio-cultural aspects and their impact on health and adiposity level. 932 adolescents were surveyed. Information regarding physical activity, sedentary behaviour, anthropometric index and family characteristics (structure, dynamics and functioning) was estimated by adolescents answering a questionnaire. The sample's average age was 16.07±1.09 years old, 56.3 % were female, 66.3 % had a low level of physical activity and 51.9 % were sedentary. A lack of physical activity occurred more frequently in females (56.8 % cf 41.5 %: p=0.000); family characteristics did not influence such risk behaviour. A relationship between physical activity and sedentary lifestyle with BMI could not be demonstrated, whilst waist circumference was associated with risky behaviour patterns. Teenagers in good health were more active (36.1 % cf 27 %) and less sedentary (49.3 % cf 59.4 %) than those for whom an unhealthy state was reported. Sedentary behaviour and a lack of physical activity were more determined by socio-demographic factors than family aspects, such behaviour pattern having a direct influence on the adolescents' health.

    Background Sexual activities are increasingly changing from the cultural point of view what they used to be. Knowledge of these practices among adolescents may be a basis to create awareness among adolescents on practices that involve risks. This study aims to assess sexual practices among unmarried adolescents in Tanzania. Methods A cross-sectional survey was conducted among in-school and out-of-school but unmarried adolescents aged 10 to 19 in five locations in Tanzania. A questionnaire was used to collect information and to characterize sexual practices among these adolescents. Results About 32% of adolescents reported being sexually active; a higher proportion being males than females. The only inquired and reported sexual practices include vaginal sex, masturbation, oral and anal sex. About 15% of sexually active adolescents reported having multiple sexual partners. Significantly more males reported having multiple partners than females. Nearly 42% of sexually active adolescents reported having used a condom during most recent sexual act. Females reported older partners at first sexual act. Conclusion Adolescents experience several sexual practices that include penetrative and non-penetrative. More males reported being sexually active than females. Despite adolescents reporting having multiple sexual partners, reported condom use during the most recent sexual act was low. We advocate for a more enhanced approach of reproductive health education that includes safer sex to adolescents without forgetting those in-schools. PMID:19804651

    Given the importance of assessing depressive symptoms and suicidal ideation in adolescents with eating disorders (EDs), the aim was to provide normative data on the Children's Depression Inventory (CDI) for female adolescents presenting for treatment of an ED. The data source was the Helping to Outline Paediatric Eating Disorders (HOPE) Project registry (N = 1000), a prospective, ongoing registry study comprising consecutive pediatric tertiary ED referrals. Females (N = 256; 12-17 years) with DSM-5 EDs completed the CDI at intake. Results on the CDI revealed a pattern of increasing depressive scores with age and higher scores among patients with anorexic spectrum disorders. The prevalence of suicidal ideation was high and had the same pattern as CDI scores. The mean score on the CDI in the sample was higher than community samples and clinical samples of adolescents with post-traumatic stress disorder, obsessive compulsive disorder, and other clinical disorders. Females adolescents with EDs are at high-risk of depression and suicidal ideation. These data provide information about variation in CDI scores to guide clinicians in interpretation of scores. © 2014 Wiley Periodicals, Inc.

    To determine the frequency, experiences and correlates of sexual violence among female adolescents in Riyadh city, Kingdom of Saudi Arabia. A cross-sectional survey was conducted in 2 schools in Riyadh city for adolescent females starting from January 2008 for 3 months. Five classes with 25 students in each were randomly selected from intermediate and secondary grade of each school. Four hundred and nineteen students were included. A self-answering questionnaire was distributed and collected after 15 minutes by 3 research assistants. Forty-two adolescent students (10%) were exposed to sexual violence. Only 31% of the students were taught how to react to sexual violence. Students whose order was > or = 5th among siblings and who had unsupportive parents in discussing sexual issues were more exposed to sexual violence (chi2=4.02, p=0.044, chi2=4.24, p=0.039). Being > or = 5th in order among siblings and having unsupportive parents in discussing sexual issues were correlates for exposure to sexual violence.

    Carlson's developmental theory of self-concept provides a theoretical explanation for equivalent levels of self-esteem among both sexes, despite sex differences in self-concept. The present study tests the applicability of Carlson's theory for a sample of gifted and talented female adolescents by examining three dimensions of possible self-esteem antecedents: actual talent ratings, self-perceptions of talent, and personality attributes. According to Carlson, talent ratings, self-perceptions, and personality attributes consistent with the feminine gender-role stereotype and a social orientation should emerge as positive predictors of the female adolescent's social self-esteem. Results of the regression analyses indicate that the best prediction of the social self-esteem of gifted and talented female adolescents is obtained from a combination of stereotypic feminine socially oriented and stereotypic masculine personally oriented predictor variables. For this sample, constructs such as androgyny appear to be more relevant to the understanding of social self-esteem than dichotomies such as personal-social orientation.

    Little is known about the influence of different types and sources of social support on physical activity in adolescents. The aim of this study was to analyse the association between physical activity and different types and sources of social support in adolescents. The sample consisted of 2,859 adolescents between 14-19 years of age in the city of João Pessoa, in Northeastern Brazil. Physical activity was measured with a questionnaire and social support from parents and friends using a 10-item scale five for each group (type of support: encouragement, joint participation, watching, inviting, positive comments and transportation). Multivariable analysis showed that the types of support provided by parents associated with physical activity in adolescents were encouragement for females (P < 0.001) and adolescents between 14-16 years of age (P = 0.003), and transportation (P = 0.014) and comments (P = 0.037) for males. The types of social support provided by friends were: joint participation in male adolescents (P < 0.001) and in these 17-19-year-olds (P < 0.001), and comments in both genders (males: P = 0.009; females: P < 0.001) and 14-16-year-olds (P < 0.001). We conclude that the type of social support associated with physical activity varies according to its source, as well as the gender and age of the adolescents.

    Adenovirus 36 (Ad36) is the only adenovirus to date that has been linked with obesity in humans. Our previous studies in late-adolescent females suggest that excess weight in the form of fat mass is associated with lower cortical bone strength. The purpose of this study was to assess the relationship between Ad36-specific antibodies, adiposity, and bone strength in our sample of late-adolescent females. A cross-sectional study of 115 females aged 18 to 19 years was performed. Participants were classified according to adiposity by dual-energy X-ray absorptiometry (body fat percentage as normal-fat [<32% body fat; n=93] or high-fat [≥ 32% body fat; n=22]), and according to the presence of Ad36-specific neutralizing antibodies. Peripheral quantitative computed tomography measured bone parameters at the 4% (trabecular bone) and 20% (cortical bone) site, and muscle cross-sectional area (MCSA) at the 66% site, from the distal metaphyses of the radius and the tibia. Bone strength was determined from volumetric bone mineral density and bone geometry to calculate bone strength index (BSI; trabecular site) and polar strength–strain index (SSI; cortical site). After adjustment for MCSA and limb length, radial SSI was lower in Ad36+ versus Ad36− subjects from the high-fat group (p<0.03), but not the normal-fat group. No significant differences were observed between groups in tibial SSI or BSI. These data support an association of adiposity and cortical bone strength at the radius with the presence of neutralizing antibodies to Ad36 in late-adolescent females. PMID:23296755

    Objective The purpose of this study was to examine, using structural equation modeling, the associations between nominated friend physical activity (PA), friend social support with individual psychological factors, and adolescent PA. Methods Data were obtained from EAT 2010 (Eating and Activity Among Teens), a large cross-sectional study conducted in 20 middle and high schools. The sample consisted of 1951 adolescents (mean age: 14.25 ± 1.96, 54% female, 68% ethnic minorities). PA, parent and friend socia l support (perceived social support for PA from parents and friends), and psychological measures (PA enjoyment, PA self-efficacy, and PA barriers) were assessed by self-report questionnaires. The SEM analysis consisted of 1 observed variable: friend PA, and 2 latent constructs: psychological factors, perceived social support. Results The model was a good fit, indicating that there were significant direct effects of both friend PA (P < .01) and psychological factors (P < .0001) on adolescent PA. In addition, psychological factors mediated the association between friend PA and adolescent PA. Conclusion The results of this model suggest that psychological factors and friend PA are associated with adolescent PA, and that psychological factors may play an important role. Future studies should further examine the association of both friend PA and psychological variables with adolescent PA. PMID:27172613

    The aim of this study was to assess change in the number of adolescent females prescribed hormonal contraception in primary care following the publication in the United Kingdom of the Social Exclusion Unit report on Teenage Pregnancy. We conducted a retrospective observational study of 320 primary care practices in Scotland. Hormonal contraceptive prescribing to girls aged <16 years and those aged 16-19 years was assessed for April 1 to March 31 for the study years 2000-2001 to 2005-2006 from Scottish primary care practice data. Between 2000-2001 and 2005-2006, the proportion of girls aged <16 years and those 16-19 years who were prescribed hormonal contraception by their primary care physicians increased by 82% (p < .001) and 53% (p < .001) respectively. The increase became significant from age 12 years for the combined oral contraceptive, 14 years for the progestogen-only pill, and 15 years for depot progestogens. By 2005-2006, 2.9% of girls aged <16 years and 40.5% of those aged 16-19 years were prescribed some form of hormonal contraception by their primary care physicians. The small number of girls aged <12 years who were prescribed hormonal contraception remained constant over the study period. Since the publication in the United Kingdom of the Social Exclusion Unit Report on Teenage Pregnancy, there has been a significant increase in the number of female adolescents aged > or =12 years prescribed hormonal contraception by their primary care physicians. However the number of individuals prescribed hormonal contraception still remains relatively low in comparison to the reported levels of sexual activity among adolescents in the United Kingdom.

    Objectives We assessed the proportion of and socio-ecological factors associated with ever having had sex with female sex workers (FSWs) among heterosexual adolescents. We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs. Methods This is a cross-sectional study (response rate: 73%) of 300 heterosexually active male adolescents of 16 to 19 years attending a national STI clinic in Singapore between 2009 and 2014. We assessed the ecological factors (individual, parental, peer, school and medial influences) and sexual risk behaviors using a self-reported questionnaire. Poisson regression was used to obtain the adjusted prevalence ratios (aPR) and confidence intervals (CI). Results The proportion of heterosexual male adolescents who had ever had sex with FSWs was 39%. Multivariate analysis showed that significant factors associated with ever having had sex with FSWs were sex initiation before 16 years old (aPR 1.79 CI: 1.30–2.46), never had a sexually active girlfriend (aPR 1.75 CI 1.28–2.38), reported lower self-esteem score (aPR 0.96 CI: 0.93–0.98), higher rebelliousness score (aPR 1.03 CI: 1.00–1.07) and more frequent viewing of pornography (aPR 1.47 CI: 1.04–2.09). Lifetime inconsistent condom use with FSWs was 30%. Conclusions A significant proportion of heterosexual male adolescents attending the public STI clinic had ever had sex with FSWs. A targeted intervention that addresses different levels of influence to this behavior is needed. This is even more so because a considerable proportion of adolescents reported inconsistent condom use with FSWs, who may serve as a bridge of STI transmission to the community. National surveys on adolescent health should include the assessment of frequency of commercial sex visits and condom use with FSWs for long-term monitoring and surveillance. PMID:26808561

    Over 180 million people consume cannabis globally. Cannabis use peaks during adolescence with a trend for continued consumption by adults. Notably, several studies have shown that long-term and heavy cannabis use during adolescence can impair brain maturation and predispose to neurodevelopmental disorders, although the neurobiological mechanisms underlying this association remain largely unknown. In this study, we evaluated whether, in female rats, chronic administration of increasing doses of the psychotropic plant-derived cannabis constituent, delta-9-tetrahydrocannabinol (THC), during adolescence (PND 35-45) could affect microglia function in the long-term. Furthermore, we explored a possible contribution of microglia to the development of THC-induced alterations in mood and cognition in adult female rats. Present data indicate that adolescent THC administration induces a persistent neuroinflammatory state specifically localized within the adult prefrontal cortex (PFC), characterized by increased expression of the pro-inflammatory markers, TNF-α, iNOS and COX-2, and reduction of the anti-inflammatory cytokine, IL-10. This neuroinflammatory phenotype is associated with down-regulation of CB1 receptor on neuronal cells and up-regulation of CB2 on microglia cells, conversely. Interestingly, blocking microglia activation with ibudilast during THC treatment significantly attenuates short-term memory impairments in adulthood, simultaneously preventing the increases in TNF-α, iNOS, COX-2 levels as well as the up-regulation of CB2 receptors on microglia cells. In contrast, THC-induced depressive-like behaviors were unaffected by ibudilast treatment. Our findings demonstrate that adolescent THC administration is associated with persistent neuroinflammation within the PFC and provide evidence for a causal association between microglial activation and the development long-term cognitive deficits induced by adolescent THC treatment.

    Hispanic females in their late adolescence appear to be disproportionately affected by dating violence, yet the majority of victims never seek out formal services. The purpose of this study was to explore the dating violence and the help-seeking experiences of Hispanic females in their late adolescence. Participants were recruited from a social service agency providing wrap-around services to individuals-and families affected by abuse in South Florida. Eleven in-depth qualitative interviews were conducted with Hispanic female victims of dating violence in their late adolescence (18 to 24 years of age) in English or Spanish. A thematic analysis of transcripts identified four major themes: (a) conflict, culture, and context influences Hispanic couples; (b) missed opportunities to accessing help; (c) pivotal moments are needed to access formal services; and (d) family matters. Participants of this study believed that dating violence was more normative in Hispanic relationships than “American” relationships. Although participants had opportunities to seek formal services early in their relationships, formal services were only sought after pivotal moments. Families played an important role in supporting or further victimizing the participants. Findings from this study can be used to inform interventions addressing both informal and formal sources of support for Hispanic female victims of dating violence in their late adolescence.

    Adolescence represents a transitional period which is marked by physical, social and psychological changes. Changes in body shape and physical activity especially alter and shape the psychological well-being of adolescents. The purpose of this study was to determine the role of physical activity level, body mass index and maturity status in body-related perception and self-esteem of 11-18 years old adolescents. A total of 1012 adolescents participated in this study. The "Social Physique Anxiety Scale", "Body Image Satisfaction Scale", "Physical Self-Perception Profile for Children" and "Rosenberg Self-Esteem Inventory" were administered. Physical activity level and body mass index were assessed using the "Physical Activity Questionnaire" and "Bioelectrical Impedance Analyzer", respectively. Regression analysis indicated that body mass index was the only predictor of perceived body attractiveness, social physique anxiety, body image satisfaction and self-esteem for female adolescents. For male adolescents, both physical activity and body mass index were correlated with perceived body attractiveness and social physique anxiety. Pubertal status were not correlated with self-esteem and body-related perceptions for both males and females adolescents. In summary, body mass index and physical activity plays an important role in body-related perceptions and self-esteem of adolescents.

    Cross-sectional evidence has demonstrated the importance of motor skill proficiency to physical activity participation, but it is unknown whether skill proficiency predicts subsequent physical activity. In 2000, children's proficiency in object control (kick, catch, throw) and locomotor (hop, side gallop, vertical jump) skills were assessed in a school intervention. In 2006/07, the physical activity of former participants was assessed using the Australian Physical Activity Recall Questionnaire. Linear regressions examined relationships between the reported time adolescents spent participating in moderate-to-vigorous or organized physical activity and their childhood skill proficiency, controlling for gender and school grade. A logistic regression examined the probability of participating in vigorous activity. Of 481 original participants located, 297 (62%) consented and 276 (57%) were surveyed. All were in secondary school with females comprising 52% (144). Adolescent time in moderate-to-vigorous and organized activity was positively associated with childhood object control proficiency. Respective models accounted for 12.7% (p = .001), and 18.2% of the variation (p = .003). Object control proficient children became adolescents with a 10% to 20% higher chance of vigorous activity participation. Object control proficient children were more likely to become active adolescents. Motor skill development should be a key strategy in childhood interventions aiming to promote long-term physical activity.

    This paper aims to describe the prevalence of parent-adolescent conversations about eating, physical activity and weight across sociodemographic characteristics and to examine associations with adolescent BMI, dietary intake, physical activity and sedentary behaviors. Data from two linked epidemiological studies were used for cross-sectional analysis. Parents (n=3,424; 62% females) and adolescents (n=2,182; 53.2% girls) were socioeconomically and racially/ethnically diverse. Fathers reported more parent-adolescent conversations about healthful eating and physical activity with their sons and mothers reported more weight-focused conversations with their daughters. Parents of Hispanic/Latino and Asian/Hmong youth and parents from lower SES categories engaged in more conversations about weight and size. Adolescents whose mothers or fathers had weight-focused conversations with them had higher BMI percentiles. Adolescents who had two parents engaging in weight-related conversations had higher BMI percentiles. Healthcare providers may want to talk about the types of weight-related conversations parents are having with their adolescents and emphasize avoiding conversations about weight specifically.

    To study the relationship of adolescent development and eating disorder related quality of life in Indian females. 461 female school students (aged 12-17 yrs) were recruited from middle to high socio-economic status (SES), English speaking schools in Delhi, India. Adolescent development was measured by Tanner stage and months since menarche. Subjects completed the Quality of Life for Eating Disorders questionnaire (QOL ED), which included six subscores. Correlation and partial correlation coefficient analysis to control for Body Mass Index (BMI) were performed. After controlling for BMI, all adolescent development measures were correlated with the psychological feelings (PSY) subscore. This subscore contained items relating to confusion, social unease, sadness, difficulty coping, desiring perfection and loss of control. Tanner breast stage was correlated with the eating behaviour (EB) subscore. During adolescent development, Indian girls became more aware of their psychological feelings and emotions. Only those reporting breast development were using behaviours to control their body, weight and shape. These behaviours are not associated with the presence of disordered eating thoughts, such as preoccupation with food, eating, body weight or shape.

    Menstruation has important implications on the physical and emotional well-being of adolescents' reproductive health. This study aimed to investigate the perception towards menstruation and premenstrual syndrome (PMS), to provide insight into menstrual-related education information in order to help adolescent girls manage the physical and psychological changes associated with menstruation. This cross-sectional study included 1,092 adolescent females from 94 schools in the Federal Territory of Kuala Lumpur, Malaysia. A self-administered semi-structured questionnaire was used in the data collection. The results showed the mean scores on the menstrual attitude questionnaire to be 2.80 (SD ±1.88) out of six. A total of 80.7% and 83.6% of the participants experienced one or more affective and somatic symptoms respectively in the premenstrual phase. Irritability, mood swing and tension were the three most frequently reported affective symptoms, while fatigue and menstrual cramps were highly prevalent somatic symptoms in both the premenstrual and menstrual phases. The effects on functional impairment and quality of life, in order of importance, include poor class concentration, restriction of social and recreational activities, difficulty to mingle with friends, and poor class performance. Despite the evident impact, only 10.3% of adolescent girls consulted doctors for PMS symptoms, while one-third did nothing about their condition. There were ethnic differences in the seeking of treatment for PMS. The study calls for an education program related to PMS and menstrual-related disorders to provide information and support to adolescents. This will help them to cope better with menstrual-related problems, and encourage positive attitudes to menstruation.

The following physical activity correlates were measured: attitude, self-efficacy, social support from friends and parents, and perceived environmental characteristics. Physical activity was measured using a questionnaire. Multivariable ordinal logistic regression with proportional odds model analysis showed that the following factors are positively related to physical activity levels in adolescents: attitude, self-efficacy, as well as social support from parents and friends. Physical activity intervention programs should increase self-efficacy and social support from parents and friends, as well as a positive attitude toward physical activity.

    This study aimed to identify strategies caregiving professionals at shelters discuss and use in care delivery to violence situations lived by female adolescents; and to discuss educative practice as a care technology for coping with violence. Based on qualitative research, the data were produced through interviews with caregivers at a municipal adolescent shelter and were interpreted according to content analysis. The results evidenced individual and institutional strategies for care delivery to the adolescents. In conclusion, educative actions are care technologies in the reframing process of life's value by female adolescents living on the streets or in shelters, considering the cultural diversity - a dialogical action systemized and institutionalized for coping with the violence they experience.

    Research considering physical activity (PA), physical inactivity and health outcomes among urban and rural youth has produced equivocal findings. This study examined PA, physical inactivity, sedentary behaviours and cardiorespiratory fitness (CRF) in adolescents from urban and rural communities in the Portuguese Midlands. The sample included 362 adolescents (165 males, 197 females) of 13-16 years of age. CRF was assessed by the PACER test. A GT1M accelerometer was used to record 5 consecutive days of PA and time spent sedentary. Analyses of covariance (chronological age as co-variate) were performed to test the effect of the area of residence on sedentary behaviour, PA and CRF. Urban youth of both sexes spent less time in sedentary activities than rural youth. Urban males were more active than rural peers at the weekend, whereas urban females were significantly less active than rural females on week days and across all days assessed. Rural youth of both sexes had higher levels of CRF than urban youth. Area of residence was related to aerobic fitness, PA and time spent in sedentary behaviours among Portuguese youth. Interventions seeking to enhance health and active lifestyles in Portuguese youth should consider the potential impact of socio-geographic factors.

    This exploratory study compared the impact of sex education provided by parents to female adolescents against the same education provided in formal settings to female adolescents. Females, 16-24 years old, attending an adolescent medicine clinic in an urban area of the South were recruited prior to examination. Each patient completed an anonymous self-administered questionnaire. Data from 110 respondents were analyzed to compare those indicating they had learned about each of four topics from parents to those not indicating learning about all four topics from a parent. The same process was repeated relative to learning about the four topics in formal educational settings. In controlled, multivariate, analyses, adolescents not communicating with parents on all four topics were nearly five times more likely to report having multiple sex partners in the past three months. Further, these adolescents were 3.5 times more likely to have low self-efficacy for condom negotiation, 2.7 times more likely to report ever using alcohol or drugs before sex, and about 70% less likely to have ever talked about HIV prevention with a partner before engaging in sex. Differences relative to learning about the four topics in formal settings were not found. Findings suggest that teen females (attending teen clinics) may experience a protective benefit based on communication with parents. This protective effect was not observed for education delivered in formal settings.

    Although adolescents with delinquency are known to have higher-than-average rates of depression or substance use disorder (SUD), research on the topic is inconsistent. It remains unclear weather depression or SUD leads to delinquency, whether delinquency leads to depression or SUD, or whether there is bi-directionality. Utilizing the National Survey of Child and Adolescent Well-Being (Wave I: 2008-2009; Wave II: 18 months later: N=5872), we used logistic regression to predict depression from delinquency (and vice versa), and SUD from delinquency (and vice versa). After inclusion of control variables, we found that females with minor theft in Wave I were more than 4 times as likely (adjusted odds ratio [aOR]=4.34; 95% CI: 1.10-17.16) as females without minor theft to be depressed in Wave II, and those with public disorder in Wave I were almost 3 times as likely (aOR=2.74; 95% CI: 1.03-7.30) as those without public disorder to have SUD in Wave II. Overall delinquency also predicted depression or SUD, and SUD predicted delinquency. Practitioners could address risk for depression or SUD among child welfare-involved adolescent females by focusing on overall delinquency or on specific types of delinquency (minor theft for depression and public disorder for SUD) and by offering interventions (e.g., cognitive-behavioral psychotherapy) that have been shown to be effective in preventing depression or SUD. In addition, with respect to our finding that SUD predicts delinquency among adolescent females, practitioners can help prevent delinquency by offering interventions (e.g., intensive outpatient treatments) that have well documented effectiveness in addressing SUD.

    No study has yet compared body fat distribution before and after weight restoration in adolescent and adult patients with anorexia nervosa (AN) treated according to the same protocol. The study was set up to measure body fat distribution before and after short-term weight restoration in adolescent and adult patients with AN treated according to the same protocol in a specialist inpatient unit. We recruited 33 consecutive adolescent female patients with AN, and 33 controls matched by age and post-treatment BMI centile, as well as 33 adult female patients with AN, and 33 controls matched by age and post-treatment BMI. Dual-energy X-ray absorptiometry (DXA) was used to assess body composition before and after short-term weight restoration (BMI ≥ 18.5 kg/m²). Compared with controls, both adolescents and adults with AN showed that a greater amount of fat was lost from the extremities than the trunk before weight restoration, and that there was a central adiposity phenotype after short-term weight restoration. There were no significant differences in body fat distribution between adolescents and adults with AN before or after short-term weight restoration. Adolescent and adult females with AN have similar body fat distribution both before and after short-term weight restoration, and show a central adiposity phenotype after short-term weight restoration. The clinical implications of this finding are as yet unknown. Clinical Trials Registry- Regional Fat Distribution in Adolescent Girls and Adults with Anorexia Nervosa (ISRCTN73572502).

    Since the passage of Title IX in 1972, female sports participation has dramatically increased. The benefits of physical activity, including decreased risk for heart disease and diabetes as well as improved body image and self-esteem, far outweigh the risks. However, a select population of adolescent and young adult females may experience symptoms related to the female athlete triad (Triad), which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density (BMD). These conditions often manifest clinically as disordered eating behaviors, menstrual irregularity, and stress fractures; an individual may suffer from 1 or all of the Triad components simultaneously. Because of the complex nature of the Triad, treatment is challenging and requires a multidisciplinary approach. Team members often include a physician, psychologist or psychiatrist, nutritionist or dietitian, physical therapist, athletic trainer, coach, family members, and most importantly, the patient. A thorough physical examination by a primary care physician is essential to identify all organs/systems that may be impacted by Triad-related conditions. Laboratory tests, assessment of bone density, nutritional assessment, and behavior health evaluation guide the management of the female athlete with Triad-related conditions. Treatment of the Triad includes adequate caloric consumption to restore a positive energy balance; this is often the first step in successful management of the Triad. In addition, determining the cause of menstrual dysfunction (MD) and resumption of menses is very important. Nonpharmacologic interventions are the first choice; pharmacologic treatment for MD is reserved only for those patients with symptoms of estrogen deficiency or infertility. Lastly, adequate intake of calcium and vitamin D is critical for lifelong bone health. For this review, a comprehensive search of relevant databases from the earliest dates to July 2016 was performed. Keywords

  18. Attention and Working Memory in Female Adolescents With Chronic Pain and Pain-free Female Adolescents: A Preliminary Pilot Study.

    Adolescents with chronic pain often report inattention and poor memory. There has been little research on cognitive function in this population. The goal of this preliminary pilot study was to examine differences in cognitive function between adolescents with chronic pain to pain-free adolescents. All participants completed baseline assessments of pain, school absences, depression, anxiety, and sleep habits. Standardized neurocognitive tests were used to examine cognitive function with a focus on working memory and attention. Recruitment from the chronic pain clinic resulted in a female sample of 13 individuals (largely reflective of the clinical population). Pain-free age-matched and sex-matched individuals (n=12) were therefore also recruited as controls. Individuals with chronic pain had significantly lower working memory scores than controls. Differences were found between groups on the most difficult selective attention task and not on tests of sustained attention, divided attention, or attentional switching. In a stepwise regression with baseline characteristics entered in the first step, pain accounted for approximately 15% of the variance in working memory and medication score counted for 49% of the variance. This pilot study is the first study to examine differences in working memory and attention between participants with chronic pain and pain-free adolescents. Our findings suggest that chronic pain may negatively affect adolescents' working memory function and highlights the risk for cognitive difficulties and problems with educational progression in addition to negative health and social effects associated with chronic pain. The study provides a starting point for more research and has the potential to direct better identification and treatment of these cognitive deficits.

  20. The effects of early-life stress on dopamine system function in adolescent female rats.

    During adolescence, many neural systems, including the dopamine system, undergo essential remodeling and maturation. It is well known that early-life stress (ELS) increases the risk for many psychopathologies during adolescence and adulthood. It is hypothesized that ELS interferes with the maturation of the dopamine system. There is a sex bias in the prevalence of stress-related mental disorders. Information regarding the effects of ELS on brain functioning in females is very limited. In the current study, maternal separation (MS) procedures were carried out to study the effects of ELS on dopamine system functioning in adolescent female rats. Our study showed that MS increased the density of tyrosine hydroxylase immunoreactive fibers in the prelimbic cortex (PLC) and nucleus accumbens (Acb). These changes were accompanied by a decrease in the level of D5 receptor mRNA and an increase in D2 receptor mRNA expression in the PLC of MS females. Conversely, D1 and D5 receptor mRNA levels were augmented in the caudate putamen (CPu), while the expression of the D3 dopamine receptor transcript was reduced in MS females. Additionally, in the Acb, MS elicited a decrease in D2 receptor mRNA expression. At the behavioral level, MS increased apomorphine-induced locomotion; however, it did not change locomotor responses to selective D1/D5 receptor agonist and attenuated D2/D3 receptor agonist-triggered locomotion. Moreover, MS decreased D1/D5 receptor agonist-induced grooming behavior. These results indicate that ELS disrupts dopamine receptor function in the PLC and basal ganglia during adolescence in females and may predispose them to psychopathologies during adolescence and adulthood.

  2. Physical activity, cardiorespiratory fitness, and metabolic syndrome in adolescents: A cross-sectional study

    PubMed Central

    2011-01-01

    Background In adults, there is a substantial body of evidence that physical inactivity or low cardiorespiratory fitness levels are strongly associated with the development of metabolic syndrome. Although this association has been studied extensively in adults, little is known regarding this association in adolescents. The aim of this study was to analyze the association between physical activity and cardiorespiratory fitness levels with metabolic syndrome in Brazilian adolescents. Methods A random sample of 223 girls (mean age, 14.4 ± 1.6 years) and 233 boys (mean age, 14.6 ± 1.6 years) was selected for the study. The level of physical activity was determined by the Bouchard three-day physical activity record. Cardiorespiratory fitness was estimated by the Leger 20-meter shuttle run test. The metabolic syndrome components assessed included waist circumference, blood pressure, HDL-cholesterol, triglycerides, and fasting plasma glucose levels. Independent Student t-tests were used to assess gender differences. The associations between physical activity and cardiorespiratory fitness with the presence of metabolic syndrome were calculated using logistic regression models adjusted for age and gender. Results A high prevalence of metabolic syndrome was observed in inactive adolescents (males, 11.4%; females, 7.2%) and adolescents with low cardiorespiratory fitness levels (males, 13.9%; females, 8.6%). A significant relationship existed between metabolic syndrome and low cardiorespiratory fitness (OR, 3.0 [1.13-7.94]). Conclusion The prevalence of metabolic syndrome is high among adolescents who are inactive and those with low cardiorespiratory fitness. Prevention strategies for metabolic syndrome should concentrate on enhancing fitness levels early in life. PMID:21878095

    The purpose of the study was to examine the association between adolescents' psychological distress and their sexually transmitted disease/human immunodeficiency virus (STD/HIV)-associated sexual behaviors and attitudes. Sexually active black adolescent females (N = 522) completed, at baseline and again 6 months later, a self-administered questionnaire that assessed sexual health attitudes and emotional distress symptoms (using standardized measures, alpha =.84), a structured interview that assessed STD/HIV-associated sexual risk behaviors, and a urine screen for pregnancy. In multivariate analyses, controlling for observed covariates, adolescents with significant distress at baseline were more likely than their peers, after 6 months, to be pregnant (adjusted odds ratio [AOR]: = 2.0), have had unprotected vaginal sex (AOR = 2.1), have nonmonogamous sex partners (AOR = 1.7), and not use any form of contraception (AOR = 1.5). Additionally, they were also more likely to: perceive barriers to condom use (AOR = 2.2), be fearful of the adverse consequences of negotiating condom use (AOR = 2.0), perceive less control in their relationship (AOR = 2.0), have experienced dating violence (AOR = 2.4), feel less efficacious in negotiating condom use with a new sex partner (AOR = 1.6), and have norms nonsupportive of a healthy sexual relationship (AOR = 1.7). The findings suggest that psychological distress is predictive over a 6-month period of a spectrum of STD/HIV-associated sexual behaviors and high-risk attitudes. Brief screening to detect distress or depressive symptoms among adolescent females can alert the clinician to the need to conduct a sexual health history, initiate STD/HIV-preventive counseling, and refer for comprehensive psychological assessment and appropriate treatment. Among adolescents receiving STD treatment, those with even moderate emotional distress may be at heightened risk for further unhealthy outcomes. STD/HIV interventions should also consider

    Low IQ is associated with high BMI in childhood. There are inconsistent findings on the association between low SES and high BMI. Youth with low IQ have been reported to have poorer health behaviors, such as poor nutrition and less physical activity. Low IQ is significantly associated with obesity for both male and female adolescents, though more strongly for female adolescents. Physical activity has a mediating effect on the association between low IQ and obesity among both male and female adolescents, though more strongly for male adolescents. The association between low IQ and obesity is strongest among adolescents from high SES backgrounds. Previous studies have shown an association between low intelligence quotient (IQ), high body mass index and low socioeconomic status (SES). This study examined the cross-sectional association between IQ and obesity, exploring the roles of gender, SES and physical activity in this association. Subjects were 235,663 male and 169,259 female adolescents assessed by the Israeli military draft board. Low IQ was significantly associated with increased odds of obesity among male (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.36-1.52) and female adolescents (OR = 1.61, 95% CI = 1.51-1.73); this association was significantly stronger among female adolescents. Sobel tests indicated that physical activity had a significant mediating effect on this association for male and female adolescents, although more strongly for male adolescents. Dividing the sample according to SES, the association between low IQ and obesity was strongest in the high SES group (male adolescents: OR = 1.26, 95% CI = 1.10-1.43, female adolescents: OR = 1.61, 95% CI = 1.38-1.89), even when controlling for physical activity. The findings suggest that low IQ is associated with increased odds of obesity, particularly in female adolescents and in adolescents with high SES. Physical activity has a mediating effect on this

    To identify correlates of parent-daughter communication about abortion among nonpregnant adolescents. Nonpregnant African-American females aged 14-17 years attending one of three charter schools on Chicago's South Side were recruited and surveyed regarding parental relationship quality, attitudes toward sexual health, and communication about sexual health. We calculated odds ratios (ORs) for ever discussing abortion using multivariable logistic regression. Of the 265 adolescents, 43.0% had ever discussed abortion with a parent. While 72.3% would voluntarily tell a parent about an abortion plan, 19.2% feared a parent would physically hurt her, punish her, or evict her. Ever communicating about abortion was significantly associated with having a mother who had a teen pregnancy (OR, 1.99; 95% confidence interval [CI], 1.05-3.78); having a prochoice abortion attitude (OR, 3.27; 95% CI, 1.29-8.25); having discussed sexually transmitted infections (OR, 2.97; 95% CI, 1.13-7.77) or birth control (OR, 2.96; 95% CI, 1.35-6.47) with a parent; and perceived parental approval of adolescent sexual activity (OR, 3.07; 95% CI, 1.20-7.88). Ever communicating about abortion was inversely related to being sexually experienced (OR, .48; 95% CI, .23-.99) or anticipating supportive parental reactions to an abortion decision (OR, .31; 95% CI, .13-.75). Although almost half of our sample was sexually active, the majority had never talked to their parents about abortion. Some reported fears of harm should the situation arise. Public policy should focus on promoting parent-daughter communication before an unwanted pregnancy rather than forcing communication after it occurs.

    Central to the development of culturally competent violence prevention programs for Hispanic youth is the development of psychometrically sound violence risk and outcome measures for this population. A study was conducted to determine the psychometric properties of two commonly used violence measures, in this case for Mexican American adolescent females. The Conflict Tactics Scales (CTS2) and the Past Feelings and Acts of Violence Scale (PFAV) were analyzed to examine their interitem reliability, criterion validity, and discriminant validity. A sample of 150 low-risk and 150 high-risk adolescent females was studied. Discriminant validity was indicated by the perpetrator negotiation scale and by the victim psychological aggression and sexual coercion scales of the CTS2 and the PFAV. Analysis indicates that the CTS2 scales and the PFAV demonstrate adequate reliability, whereas strong criterion validity was evidenced by eight of the CTS2 scales and the PFAV.

    This study was performed to investigate relations between psychopathology and psychopathy in adolescent female and male detainees. We examined 91 male and 123 female adolescent detainees (aged 14-19) for psychopathology -using the Youth Self Report, the Overt Aggression Scale-Modified and a Conduct Disorder Self Report Scale- and for psychopathic dimensions using the psychopathy checklist youth version (PCL:YV). Based on a linear regression analysis we compared the specific associations between psychopathology and psychopathy in both male and female delinquent juveniles. Our results revealed higher scores for externalizing behavior and psychopathic dimensions in delinquent males, and higher internalizing problem scores in delinquent females. Furthermore, we found a positive relationship between suicidal behavior and the psychopathy total score as well as the affective, the lifestyle and the antisocial dimension only in girls. No association was found for suicidal behavior in boys. Regarding anxious-depressive behavior, we found a negative relation to the psychopathy total score and to the affective psychopathy factor for the boys. Expectedly, the population of incarcerated adolescents exhibited a high prevalence of psychopathology. At the same time our results referred to meaningful gender-related differences with respect to associations with psychopathy. The gender-related differences in psychopathological symptoms could indicate varied subtypes of psychopathy in boys and girls.

    To determine whether school context influences the BMI of adolescent males and females. Our sample was 17,007 adolescents (aged 12-19) from the National Longitudinal Study of Adolescent Health (Add Health). We used gender-stratified multilevel modeling to examine the contribution of schools to the overall variance in adolescent BMIs, calculated from self-reported weight and height. We then examined the associations of individual attributes with BMI after controlling for the average BMI of the school and the association of two school-level variables with BMI. Participants attended schools that were segregated by race/ethnicity and socioeconomic status (SES). In females, when controlling only for individual-level attributes, individual household income was inversely associated (beta = -0.043, P = 0.01) while Hispanic (beta = 0.89, P < 0.001) and black (beta = 1.61, P < 0.001) race/ethnicity were positively associated with BMI. In males, Hispanic (beta = 0.67, P < 0.001) race/ethnicity was positively associated with BMI; there was no difference in the BMIs of blacks compared with whites (beta = 0.24, P = 0.085). After controlling for the school racial/ethnic makeup and the school level median household income, the relationship between individual race/ethnicity and BMI was attenuated in both male and female adolescents. Higher school level median household income was associated with lower individual BMIs in adolescent girls (gamma = -0.37, P < 0.001) and boys (gamma = -0.29, P < 0.001) suggesting a contextual effect of the school. Male and female adolescents attending schools with higher median household incomes have on average lower BMIs. Resources available to or cultural norms within schools may constitute critical mechanisms through which schools impact the BMI of their students.

    Purpose To examine the differences in depressive symptoms and anxiety between (a) normal weight and overweight, and (b) morning type and evening type (sleep chronotype) adolescent girls. The interaction of sleep chronotype and weight and depressive symptoms and anxiety were also examined. Method The design consisted of a cross-sectional study of 264 adolescent females (mean age= 14.9 ± 2.2, range 11–17 years). Sleep chronotype, depressive symptoms, and anxiety were obtained by self-report questionnaire. The mean of three measurements of height and weight was used to calculate the body mass index (BMI). BMI was plotted on the CDC BMI-for-age growth charts to obtain percentile ranking. Participants were categorized into two groups according to BMI percentile: normal weight (<85th percentile) and overweight (≥85th percentile). Results Compared with normal-weight females, overweight females were more likely to be non- Caucasian, lower socioeconomic status, have more advanced pubic hair and breast stages, and earlier age at menarche. No differences were observed with respect to sleep chronotype, depressive symptoms, and trait anxiety between normal weight and overweight females. Evening chronotype was associated with more depressive symptoms (β = −.65, p < .01) and higher trait anxiety (β =−.22, p < .05). Evening chronotype was associated with more depressive symptoms in both normal-weight and overweight females. However, the association was stronger in overweight females. Conclusions Individually, sleep and weight impact physical and mental health during adolescence. The combination of evening chronotype and overweight appears to have the strongest association on the emotional health of adolescent females. Further investigations are needed to provide potential biological mechanisms for this relationship. PMID:19465319

    This study looks at the relationship between tobacco consumption and the physical activity and fitness levels of adolescents. In a sample of 533 adolescents, both a questionnaire to obtain information regarding tobacco consumption and the International Physical Activity Questionnaire for information on physical activity were implemented; a battery of tests to assess physical fitness were also applied. Tobacco consumption was significantly higher in females (32.5%) than in males (25.7%). Levels of physical activity in both males and females were significantly associated with tobacco consumption (p<0.0005). Moreover, subjects who consumed tobacco showed lower overall averages in physical fitness tests than those who did not (4.26 vs. 5.77 in males and 4.54 vs. 6.71 in females). Tobacco consumption is therefore shown to be related to lower levels of physical activity and physical fitness in adolescents.

    The prevalence of obesity in childhood and adolescence has increased in Mexico. This increase can be explained partly by a decrease in physical activity. The objective of this study was to assess the association between the prevalence of obesity and overweight with physical activity and inactivity among Mexican adolescents. We analyzed data from a longitudinal study with baseline and follow-up measures in 446 adolescents 12 to 17 years old, attending public schools in Cuernavaca, Morelos, Mexico. We collected information on weight, physical activity and demographic characteristics. Obesity and overweight were determined using as indicador the body mass index, and the cutoff points proposed by the International Obesity Task Force. The baseline prevalence of obesity or overweight was 37.22% (42.99% for males and 30.95% for females), and in the final measure 34.30% (38.46% for males and 32.28% for females). The median time of TV viewing was 3.90 h/d, with 0.73 h/d dedicated to vigorous physical activity and 0.58 h/d to moderate physical activity. Using logistic regression, after adjustment for obesity in the baseline measure, sex and clustering by school, we found no significant associations between the prevalence of obesity or overweight with time dedicated to TV viewing, vigorous or moderate physical activity. However, when conducting the analysis with an interaction term by sex, we found significantly lower risk of obesity or overweight associated with an increase in vigorous physical activity among males only (beta = 0.22, 95% CI (0.05, 0.89). Results suggest that vigorous physical activity may reduce the risk of obesity or overweight among male adolescents.

    The purpose of this study was to determine whether the relationships between short-term power and body dimensions in young females were similar whatever the age of the individuals. A cohort of 189 prepubescent (mean age 9.5 years), adolescent (mean age 14.4 years) and young adult (mean age 18.2 years) females performed three all-out sprints on a friction-loaded cycle ergometer against three braking forces corresponding to applied loads of 25, 50 and 75 g.kg-1 body mass (BM). For each sprint, peak power including flywheel inertia was calculated. Results showed that a braking load of 75 g.kg-1 BM was too high for prepubescent and adolescent girls. Therefore, when measuring short-term cycling performance in heterogeneous female populations, a braking load of 50 g.kg-1 BM (0.495 N.kg-1 BM) is recommended. During growth, cycling peak power (CPP; defined as the highest peak power obtained during the three sprints) increased, as did total BM, fat-free mass (FFM) and lean leg volume (LLV) (P < 0.001). Analysis of covariance revealed that the slopes of the linear relationships between CPP and biometric characteristics were similar in the three groups (P > 0.7 for the CPP/BM and CPP/FFM relationships, and P > 0.2 for the CPP/LLV relationship). However, the adjusted means were always significantly higher in young women (P < 0.001) compared with both of the other groups. Although differences in performance during anaerobic cycling in growing females are primarily dependent upon body dimensions, other as yet undetermined factors may be involved during late adolescence.

    Extracurricular activities provide adolescents with a number of positive personal and interpersonal developmental experiences. This study investigated whether developmental experiences that occurred during extracurricular activities were linked to a more positive self-concept for Australian adolescents, and whether this link was particularly salient for youth from disadvantaged schools. Adolescents (N = 1,504, 56% Female) from 26 diverse high schools across Western Australia were surveyed. The findings revealed that adolescents from low socio-economic status schools who participated in extracurricular activities had a more positive general self-worth and social self-concept than adolescents from similar socio-economic schools who did not participate in any extracurricular activities. Furthermore, the positive developmental experiences that occurred during extracurricular activities predicted a more positive general self-worth and social and academic self-concept, and this link was stronger for youth from low SES schools. These findings suggest that the developmental experiences afforded by extracurricular activities may foster positive adolescent development.

    Hart, Leary, and Rejeski have developed the Social Physique Anxiety Scale (SPA), a measure of the anxiety experienced in response to having one's physique evaluated by other people. The present study cross-validated the psychometric properties of this measure in a sample (N = 236) of adolescent competitive female gymnasts. Employing structural equation modeling, the proposed unidimensional factor structure of the SPA was supported, although some questions regarding the robustness of the fit are raised. Construct validity was demonstrated by significant inverse relationships between aspects of physical efficacy (perceived physical ability and physical self-presentation confidence) and degree of social physique anxiety. These findings are discussed in terms of possible alternative factor structures and integration of social anxiety and other psychosocial constructs to better understand physical activity behavior.

    The aim was to estimate the prevalence of metabolic syndrome (MetS) criteria, elevated C-reactive protein (CRP), and physical activity (PA) as well as the odds of MetS criteria in those active versus inactive utilizing a representative sample of U.S. adolescents. The study sample (n = 676) included male and female adolescent (12-17 years) participants in the 2007-2010 National Health and Nutrition Examination Survey. The criteria analyzed were based on a modified definition of MetS using the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults. Current adult cut points were used to determine elevated CRP. Activity was estimated using reported days per week and minutes per day of moderate/vigorous PA. The MetS criteria with the highest and lowest overall prevalence estimates were elevated fasting glucose and elevated blood pressure (20.7% [95% confidence interval, 17.02-24.38] and 5.7% [95% confidence interval, 3.70-7.70], respectively). The prevalence of elevated CRP was 7.1% (6.3% and 7.8% in males and females, respectively; p = .42). The prevalence of insufficient PA was 75.0%. Odds of low high-density lipoprotein cholesterol were significantly lower in active adolescents when compared with inactive adolescents (odds ratio = .39, p < .05). In a representative sample of U.S. adolescents, elevated fasting glucose is the most prevalent MetS criterion. One out of five U.S. adolescents has elevated fasting glucose, and three out four do not meet the daily federal PA recommendations. Adolescents meeting the federal PA recommendation demonstrate approximately 60% lower odds of having low high-density lipoprotein cholesterol.

    To assess the perceptions of rural and urban Costa Rican adolescents regarding which barriers and motivators affect their adoption of an active lifestyle. Data were collected in focus group discussions. 108 male and female adolescents aged 12 to 18 from the 7th to 11th grades. Two urban and 1 rural high school in San José, Costa Rica. Active lifestyle; barriers and motivators for active life. Data were reviewed for emerging themes, and themes were coded using content analysis procedures. Major barriers: (a) physical education curriculum was focused on competitive sports; (b) lack of facilities in the school and community environments; (c) family did not provide good role models and reinforced the socially expected gender roles. Key motivators: (a) changed the physical education curriculum to focus on leisure and recreational activities; (b) increased the availability of facilities both in the school and in the community; and (c) provided a strong social support network. The school, community, and family environments are potential targets for physical activity interventions for adolescents. Future studies should explore in depth the influence of adolescent socialization patterns (particularly for females) in the establishment of an active lifestyle.

    To determine the relationship of participation in organized and nonorganized physical activity with fundamental movement skills among adolescents. Male and female children in Grade 8 (mean age, 13.3 yr) and Grade 10 (mean age, 15.3 yr) were assessed on six fundamental movement skills (run, vertical jump, catch, overhand throw, forehand strike, and kick). Physical activity was assessed using a self-report recall measure where students reported the type, duration, and frequency of participation in organized physical activity and nonorganized physical activity during a usual week. Multiple regression analysis indicated that fundamental movement skills significantly predicted time in organized physical activity, although the percentage of variance it could explain was small. This prediction was stronger for girls than for boys. Multiple regression analysis showed no relationship between time in nonorganized physical activity and fundamental movement skills. Fundamental movement skills are significantly associated with adolescents' participation in organized physical activity, but predict only a small portion of it.

    The present study was designed to test the effects of methylphenidate (MPH) exposure on the maturation of endocrine functioning and sexual behavior. Female rat pups received either MPH (2.0mg/kg, i.p.) or saline twice daily between postnatal days 20-35. This period of exposure represents the time just prior to puberty as well as puberty onset. Approximately five weeks after the last injection of MPH or saline, female subjects were hormone-primed and tested during their first sexual experience. Subjects were given the choice to interact with a sexually active male or a sexually receptive female rat (i.e., the partner-preference test). The partner-preference paradigm allows us to assess multiple aspects of female sexual behavior. MPH exposure during peri-adolescence delayed puberty and, when mated for the first time, affected sexual behavior (e.g., increased time spent with the male stimulus and decreased the likelihood of leaving after mounts) during the test of partner preference. When monitoring estrous cyclicity, female subjects treated with MPH during peri-adolescence frequently experienced irregular estrous cycles. The results of the present study suggest that chronic exposure to a therapeutic dose of MPH around the onset of puberty alters long-term endocrine functioning, but with hormone priming, increases sensitivity to sexual stimuli.

    1997-06-01

    This article explored the concepts of resilience, equal opportunity, and coping within a person-process-context model among urban Black adolescents in the US. Data were obtained from narrative accounts and interviews among 20 pregnant and 16 nonpregnant Black female adolescents aged 17 and 19 years. Respondents were recruited from prenatal and family planning clinics of a large metropolitan hospital and were representative of a low-income community with many female household heads and at-risk behaviors. The instruments included a 24-item structured interview of demographic data, and the 56 item semi-structured Pregnancy Adulthood Negotiation of Status Interview (PANSI). The interview elicited responses based on concrete experience, dialogue for assessing knowledge, and an ethic of caring and personal accountability. Contextual analysis revealed seven themes: adulthood preparation, role model formulation, decision-making, protective sensibility, sex and gender role commitment, opportunity mobility, and mate selection. All females shared similar demographics. Most resided in female-headed households and were high school graduates. The subsample differed in behaviors and attitudes on church affiliation, college attendance, registered voter status, sense of care and protection of self and others, self expectancies of social mobility, dating, and mate selection. Nonpregnant females were more likely to have part-time work experience and have mothers with post-high school achievement. Low-income nonpregnant adolescents were effective contraceptors and had social mobility aspirations. Narratives suggest that nonpregnant adolescents had an inner strength and belief, and commitment to advancement of career and vocational goals. The affiliations acted as social supports. These women used skillful coping mechanisms. Clinical social workers should reinforce resilience and work values.

    Autism is a dimensional condition, representing the extreme end of a continuum of social competence that extends throughout the general population. Currently, little is known about how autistic social traits (ASTs), measured across the full spectrum of severity, develop during childhood and adolescence, including whether there are developmental differences between boys and girls. Therefore, we sought to chart the trajectories of ASTs in the general population across childhood and adolescence, with a focus on gender differences. Participants were 9,744 males (n = 4,784) and females (n = 4,960) from ALSPAC, a UK birth cohort study. ASTs were assessed when participants were aged 7, 10, 13 and 16 years, using the parent-report Social Communication Disorders Checklist. Data were modelled using latent growth curve analysis. Developmental trajectories of males and females were nonlinear, showing a decline from 7 to 10 years, followed by an increase between 10 and 16 years. At 7 years, males had higher levels of ASTs than females (mean raw score difference = 0.88, 95% CI [.72, 1.04]), and were more likely (odds ratio [OR]  = 1.99; 95% CI, 1.82, 2.16) to score in the clinical range on the SCDC. By 16 years this gender difference had disappeared: males and females had, on average, similar levels of ASTs (mean difference = 0.00, 95% CI [-0.19, 0.19]) and were equally likely to score in the SCDC's clinical range (OR = 0.91, 95% CI, 0.73, 1.10). This was the result of an increase in females' ASTs between 10 and 16 years. There are gender-specific trajectories of autistic social impairment, with females more likely than males to experience an escalation of ASTs during early- and midadolescence. It remains to be discovered whether the observed female adolescent increase in ASTs represents the genuine late onset of social difficulties or earlier, subtle, pre-existing difficulties becoming more obvious. © 2018 Association for Child and Adolescent Mental Health.

    The purpose of this study is to assess awareness, knowledge and beliefs about HPV, cervical cancer HPV vaccine and willingness to vaccinate among adolescent females aged 12-26 years at clinics and schools in the North West Region of Cameroon where the Cameroon Baptist Convention Health Services (CBCHS) conducted a sensitization and education campaign. A questionnaire survey was administered among female adolescents in schools and clinics. Descriptive statistics including frequencies, percentages and proportions were generated for independent variables and bivariate analyses (Chi square test) were used to assess the relationship between independent and outcome variables. Data were analyzed using SAS Version 9.2. Out of a sample of 650 adolescent girls 553 willingly participated in this anonymous survey. Awareness of HPV (86.8%), cervical cancer (82.3%), and prevention of HPV infections through vaccination (75.9%) was significantly higher than in previous studies conducted in Cameroon and other developing countries. Higher perceptions of risk were associated with being sexually active (p = 0.0013), age (p = 0.0031) and level of education (p = 0.0274). Age and educational level were associated with HPV knowledge (p = 0.007 and p = 0.0008), respectively. The mean level of interest in HPV vaccination was 4.0 (SD = 1.27), which is above the mean. Our data indicate high awareness about HPV, cervical cancer and HPV vaccine among adolescents, and interest in receiving the vaccine and learning about the disease. CBCHS' community education strategy effectively raised acceptability and generated demand for HPV vaccine, making it a potential model for HPV immunization in Cameroon and other developing countries.

    Adolescents with conduct problems are more likely to smoke, and tobacco advertising exposure may exacerbate this risk. Males' excess risk for conduct problems and females' susceptibility to advertising suggest gender-specific pathways to smoking. We investigated the associations between gender, conduct problems, and lifetime smoking and adolescents' exposure to tobacco advertising, and we examined prospective relationships with smoking behaviors. Adolescents completed baseline (2001-2004; n = 541) and 5-year follow-up (2007-2009; n =320) interviews for a family study of smoking risk. Baseline interviews assessed conduct problems and tobacco advertising exposure; smoking behavior was assessed at both timepoints. Generalized linear models analyzed gender differences in the relationship between conduct problems, advertising exposure, and smoking behavior at baseline and longitudinally. At baseline, among males, conduct problems were associated with greater advertising exposure independent of demographics and lifetime smoking. Among females at baseline, conduct problems were associated with greater advertising exposure only among never-smokers after adjusting for demographics. In longitudinal analyses, baseline advertising exposure predicted subsequent smoking initiation (i.e., smoking their first cigarette between baseline and follow-up) for females but not for males. Baseline conduct problems predicted current (i.e., daily or weekly) smoking at follow-up for all adolescents in adjusted models. The findings of this study reinforce that conduct problems are a strong predictor of subsequent current smoking for all adolescents and reveal important differences between adolescent males and females in the relationship between conduct problems, tobacco advertising behavior, and smoking behavior. The findings suggest gender-specific preventive interventions targeting advertising exposure may be warranted.

    Background While theorists have posited that adolescent depression is characterized by emotion processing biases (greater propensity to identify sad than happy facial expressions), findings have been mixed. Additionally, the neural correlates associated with putative emotion processing biases remain largely unknown. Our aim was to identify emotion processing biases in depressed adolescents and examine neural abnormalities related to these biases using high-density resting EEG and source localization. Methods Healthy (n = 36) and depressed (n = 23) female adolescents, aged 13–18 years, completed a facial recognition task in which they identified happy, sad, fear, and angry expressions across intensities from 10% (low) to 100% (high). Additionally, 128-channel resting (i.e., task-free) EEG was recorded and analyzed using a distributed source localization technique (LORETA). Given research implicating the dorsolateral prefrontal cortex (DLPFC) in depression and emotion processing, analyses focused on this region. Results Relative to healthy youth, depressed adolescents were more accurate for sad and less accurate for happy, particularly low-intensity happy faces. No differences emerged for fearful or angry facial expressions. Further, LORETA analyses revealed greater theta and alpha current density (i.e., reduced brain activity) in depressed versus healthy adolescents, particularly in the left DLPFC (BA9/BA46). Theta and alpha current density were positively correlated, and greater current density predicted reduced accuracy for happy faces. Conclusion Depressed female adolescents were characterized by emotion processing biases in favor of sad emotions and reduced recognition of happiness, especially when cues of happiness were subtle. Blunted recognition of happy was associated with left DLPFC resting hypoactivity. PMID:26032684

    2011-05-01

    A large number of female sex workers are children. Multiple studies demonstrate that up to 40% of women in prostitution started this work prior to age 18. In studies across India, Nepal, Thailand and Canada, young age at entry to sex work has been found to heighten vulnerability to physical and sexual violence victimisation in the context of prostitution, and relates to a two to fourfold increase in HIV infection. Although HIV risk reduction among adult female sex workers has been a major focus of HIV prevention efforts across the globe, no public health interventions, to date, have addressed the increased hazards and HIV risk faced by adolescent female sex workers. Beyond the structural barriers that limit access to this vulnerable group, historical tensions between HIV prevention and child protection agencies must be overcome in order to develop effective strategies to address this large scale yet little recognised human rights and HIV-related crisis.

    2006-09-01

    This research investigates the effects of extracurricular activities on alcohol use among male (n = 4,495) and female (n = 5,398) adolescents who participated in the 1990-92 National Education Longitudinal Study. Previous studies have assessed the association between extracurricular activities and alcohol use, but none have explored whether the association depends on the school context. Using a multilevel model, I examine whether school-level factors affect the relationship between involvement in athletic or nonathletic activities and changes in adolescent alcohol use from 1990 to 1992. The results indicate that the negative association between nonathletic activities and alcohol use is stronger among males in low-minority-population schools. Moreover the positive association between athletic involvement and alcohol use is stronger among females in lower-socioeconomic-status schools and males in higher-socioeconomic-status schools. I propose that these results reflect variation in high school cultures and in the resources available to schools.

    Current concepts suggest that exposure to THC during adolescence may act as a risk factor for the development of psychiatric disorders later in life. However, the molecular underpinnings of this vulnerability are still poorly understood. To analyze this, we investigated whether and how THC exposure in female rats interferes with different maturational events occurring in the prefrontal cortex during adolescence through biochemical, pharmacological and electrophysiological means. We found that the endocannabinoid system undergoes maturational processes during adolescence and that THC exposure disrupts them, leading to impairment of both endocannabinoid signaling and endocannabinoid-mediated LTD in the adult prefrontal cortex. THC also altered the maturational fluctuations of NMDA subunits, leading to larger amounts of gluN2B at adulthood. Adult animals exposed to THC during adolescence also showed increased AMPA gluA1 with no changes in gluA2 subunits. Finally, adolescent THC exposure altered cognition at adulthood. All these effects seem to be triggered by the disruption of the physiological role played by the endocannabinoid system during adolescence. Indeed, blockade of CB1 receptors from early to late adolescence seems to prevent the occurrence of pruning at glutamatergic synapses. These results suggest that vulnerability of adolescent female rats to long-lasting THC adverse effects might partly reside in disruption of the pivotal role played by the endocannabinoid system in the prefrontal cortex maturation.

    This paper examines connectedness to, communication with and monitoring of unmarried adolescents in Ghana by parents, other adults, friends and key social institutions and the roles these groups play with respect to adolescent sexual activity. The paper draws on 2004 nationally-representative survey data and qualitative evidence from focus group discussions and in-depth interviews with adolescents in 2003. Adolescents show high levels of connectedness to family, adults, friends, school and religious groups. High levels of adult monitoring are also observed, but communication with family about sex-related matters was not as high as with non-family members. The qualitative data highlight gender differences in communication. Multivariate analysis of survey data shows a strong negative relationship between parental monitoring and recent sexual activity for males and females, and limited effects of communication. Creating a supportive environment and showing interest in the welfare of adolescents appear to promote positive sexual and reproductive health outcomes.

    Suicide is the third leading cause of death among adolescents and recent data indicate that the suicide rate, particularly for young girls, is increasing. Excess body weight among adolescents has also been documented widely over the last two decades and is considered one of the most pressing public health concerns today. Previous literature has examined the relationship between actual body weight and suicidal behavior, but there is little evidence on self-perception of weight and suicidal behaviors. This study examines the relationship between body weight and suicidal behaviors using a rich longitudinal data set of a large nationally-representative sample of female adolescents to account for a number of confounding factors. The study explores the relationship, not only between actual weight status and suicidal behaviors, but also between self-perception of weight and suicidal behaviors. Using data from a nationally-representative sample of adolescents in the United States, the study ascertains the effect of body weight status on suicidal behaviors by estimating endogeneity-corrected models including school-level fixed effects to account for bi-directionality and unobserved confounders. Actual body weight status was calculated using interviewer-measured height and weight. The study also used a measure of self-perceived weight status to compare how actual versus self-perceived weight status affects suicidal behavior. Thinking about committing suicide and attempting to commit suicide in the past 12 months were utilized as dichotomous measures of suicidal behaviors. Potential mediators between suicidal behaviors and weight status such as family history of suicide, participation in risky health behaviors and parental characteristics were also controlled for in the analysis. The analytical sample consists of 5,430 adolescent females aged 11 to 18. The results suggest that both self-perceived and measured weight status (overweight or obese) increase a female adolescent

    Purpose Little is known about how adolescent sexual behaviors develop and the influence of personal or perceived social attitudes. We sought to describe how personal, perceived peer and perceived family attitudes towards adolescent sexual activity influences adolescent females’ sexual behaviors over time. Methods Between 1999–2006, 358 English-speaking females, aged 14–17 were recruited from three urban adolescent clinics. Participants completed quarterly and annual questionnaires over 4 years. Primary outcomes were engagement in eight sexual behaviors: kissing, having breasts or genitals touched, touching partners’ genitals, and oral (giving or receiving), anal, or vaginal sex. Three attitudinal scales assessed personal importance of abstinence, perceived peer beliefs about when to have sex and perceived family beliefs that adolescent sex is negative.. We used generalized estimating equations to identify predictors of each sexual behavior and compared whether personal, perceived peer or perceived family attitudes predicted sexual behaviors over time. Results The odds of reporting each sexual behavior increased with age but were lower among those whose personal or perceived family attitudes were less positive. Participants’ personal attitudes towards adolescent sex were the strongest predictor of engagement in all eight sexual behaviors even after controlling for perceived peer and perceived family attitudes. Conclusions Female adolescent’s personal attitudes towards abstinence appear to be the strongest predictor of engagement in a variety of sexual behaviors. Efforts to influence adolescent attitudes towards abstinence may be an important approach to reducing sexual behaviors that increase the risk for pregnancy and sexually transmitted infections.

    Pediatric obesity is a growing public health concern that contributes to high rates of negative long-term physical and mental health outcomes. Research focused on identifying risk for pediatric obesity has linked delay discounting, or an inclination for immediate rewards, as well as weight concern to individuals with greater Body Mass Index (BMI). The current study seeks to fill a void in the literature by examining how these two variables interact to promote higher BMI in female adolescents. Adolescent (n=60) females between the ages of 13-19years (mage=17.45, SD=1.74) of age completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Delay Discounting Questionnaire. A mediation model examined whether delay discounting accounted for the relationship between weight concern and BMI. Results indicate that in the current study weight concern was negatively related to delay discounting and delay discounting was negatively related to BMI. The overall model revealed that a partial mediation occurred [b=1.28, t(60)=4.92, p<0.01]. These results suggest that while impulsivity is an important factor to consider, other constructs may also be influential in how weight concerns contribute to greater BMI. Nevertheless, the results indicate that prevention and interventions should identify females with high levels of both weight concern and impulsivity as an increased risk for experiencing pediatric obesity and long-term negative health outcomes.

    This study investigated whether adolescent nicotine exposure in one generation of rats would impair the cognitive capacity of a subsequent generation. Male and female rats in the parental F0 generation were given twice-daily i.p. injections of either 1.0mg/kg nicotine or an equivalent volume of saline for 35days during adolescence on postnatal days 25-59 (P25-59). After reaching adulthood, male and female nicotine-exposed rats were paired for breeding as were male and female saline control rats. Only female offspring were used in this experiment. Half of the offspring of F0 nicotine-exposed breeders and half of the offspring of F0 saline control rats received twice-daily i.p. injections of 1.0mg/kg nicotine during adolescence on P25-59. The remainder of the rats received twice-daily saline injections for the same period. To evaluate transgenerational effects of nicotine exposure on complex cognitive learning abilities, F1 generation rats were trained to perform a highly structured serial pattern in a serial multiple choice (SMC) task. Beginning on P95, rats in the F1 generation were given either 4days of massed training (20patterns/day) followed by spaced training (10 patterns/day) or only spaced training. Transgenerational effects of adolescent nicotine exposure were observed as greater difficulty in learning a "violation element" of the pattern, which indicated that rats were impaired in the ability to encode and remember multiple sequential elements as compound or configural cues. The results indicated that for rats that received massed training, F1 generation rats with adolescent nicotine exposure whose F0 generation parents also experienced adolescent nicotine exposure showed poorer learning of the violation element than rats that experienced adolescent nicotine exposure only in the F1 generation. Thus, adolescent nicotine exposure in one generation of rats produced a cognitive impairment in the next generation. Copyright © 2016 Elsevier Inc. All rights

    Activity participation provides a unique context for adolescents and emerging adults to explore interests, talents, and skills and for identity work to occur. Research has found consistent gender differences in the types of activities in which males and females participate. The current study drew on Eudaimonistic identity theory to examine the subjective identity-related experiences of personal expressiveness, flow experiences, and goal-directed behaviour [Waterman, 1984; Waterman, 2004. Finding someone to be: Studies on the role of intrinsic motivation in identity formation. Identity, 4, 209-228] within a special type of activity, self-defining activities, or those activities that participants identify as being important to who they are as a person. This study also tested for gender and country differences in a sample of 572 adolescents and emerging adults from the United States, Italy, and Chile. Findings indicate gender and country differences in the types of self-defining activities for males and females, but no gender differences in the reported identity-related experiences within those activities. This finding held across the three countries. Results from Multivariate Analyses of Variance also indicate that identity-related experiences differ significantly across seven broad activity classes. Findings are discussed in the context of the growing literature on adolescent activity involvement and time use, gender, and their relations to identity exploration.

    Adolescent moderate to vigorous physical activity (MVPA) is influenced by many factors. MVPA-promotion interventions would fare better if these multiple determinants were better understood. To simultaneously assess overall and relative contributions of factors from personal, family, friend, school, and neighborhood contexts to adolescent MVPA. It was hypothesized that (1) key correlates would emerge in each context and (2) factors from more- versus less-proximal contexts would relate more strongly to MVPA. Students in grades 6-12 (n=2,793; mean age=14.4 [SD=2.0] years; 53% girls) were recruited from 20 Minnesota public schools in 2009-2010 to participate in the Eating and Activity in Teens 2010 study. Regression analyses conducted in 2013 examined factors related to weekly MVPA. Data were collected from adolescent participants, their parents and friends, school teachers and administrators, and GIS sources. Fifty multicontextual factors explained 25% of MVPA variance for boys and 27% for girls. Personal factors (e.g., self-efficacy) were most predictive of MVPA, followed by social factors (e.g., support for PA); environmental factors (e.g., access to PA resources) were least predictive of adolescent PA. Gender differences emerged for several predictors (e.g., in mutually adjusted analyses, MVPA among girls, but not boys, related positively to distance to trails and MVPA among female friends and fathers, and related negatively to perceived barriers). Stronger linkages exist between adolescent MVPA and more-proximal (personal, family, and friend) factors compared to more-distal (school and neighborhood) factors, suggesting the importance of working with adolescents, their families, and friends to promote PA.

    To examine the tracking of active travel through adolescence, and its association with body mass index (BMI) and fat mass at age 17 in a UK cohort. We analysed data collected from the Avon Longitudinal Study of Parents and Children (ALSPAC). The analyses include all participants with self-reported travel mode to school at ages 12, 14 and 16 years, and measured height, weight and body composition at age 17 ( n =2,026). Tracking coefficients were calculated for individual travel behaviours (including walking and cycling) through adolescence using Generalised Estimating Equations. Linear regression analyses examined associations between travel pattern (consistently passive, consistently active, active at two time points or active at one time point), BMI, and DXA-measured fat mass (expressed as internally derived standard deviation scores) at 17 years. Analyses were adjusted for height (where appropriate), sex, age, parental social class, and maternal education with interaction terms to assess sex differences. There was substantial tracking in active travel through adolescence, with 38.5% of males and 32.3% of females consistently walking or cycling to school. In males, a consistently or predominantly active travel pattern was associated with a lower BMI SD score at age 17 (consistently active: adjusted β =-0.23; 95% CI -0.40, -0.06; active at two time points: adjusted β -0.30; 95% CI -0.50, -0.10) compared to those with a consistently passive pattern. No associations were seen in females. Maintenance of active travel behaviours throughout adolescence may help to protect against the development of excess BMI in males. In addition to encouraging the adoption of active travel to school, public health messages should aim to prevent drop out from active travel to promote good health in youth.

    Anorexia nervosa (AN) is associated with abnormalities in biomarkers of cardiovascular risk. Arterial stiffness, as measured by pulse-wave velocity (PWV), is also a risk factor for cardiovascular disease. The aims of this study were to determine the stiffness of the aorta in female adolescents with AN and to determine if either the severity or the type of AN was associated with PWV. This was a retrospective case-control study. Adolescent patients with a clinical diagnosis of AN were included. Aortic diameter and pulse-wave transit time over a portion of the thoracic aorta were measured using Doppler echocardiography, and PWV was calculated. There were 94 female patients with AN and 60 adolescent female control subjects. There was no significant difference in age between patients with AN and control subjects (15.5 ± 1.7 vs 15.1 ± 2.6 years, P = .220). Body mass index (16.0 ± 2.4 vs 19.7 ± 2.7 kg/m 2 , P < .001) and body mass index percentile (9.4 ± 15.6 vs 45.5 ± 26.2, P < .001) were significantly lower for patients with AN than control subjects. PWV (443 ± 106 vs 383 ± 77 cm/sec, P < .001) was significantly higher in patients with AN than control subjects. Similar differences from control subjects were found in patients with AN with both lower and higher body mass index percentiles and also in patients with AN with the restrictive or the binge-purge subtype. Female adolescents with AN have increased aortic stiffness compared with control subjects. This study suggests that patients with AN may be at increased risk for future cardiovascular disease. Future studies are required to determine the reversibility of these changes with weight restoration. Copyright © 2018 American Society of Echocardiography. Published by Elsevier Inc.

    Volatile organic solvent (inhalant) abuse continues to be a major health concern throughout the world. Of particular concern is the abuse of inhalants by adolescents because of its toxicity and link to illicit drug use. Toluene, which is found in many products such as glues and household cleaners, is among the most commonly abused organic solvents. While studies have assessed outcomes of exposure to inhalants in adult male animals, there is little research on the neurobehavioral effects of inhalants in female or younger animals. In attempt to address these shortcomings, we exposed male and female Long-Evans rats to 20 min of 0, 2,000, 4,000, or 8,000 parts per million (ppm) inhaled toluene for 10 days in rats aged postnatal (PN) day 28-39 (adolescent), PN44-PN55, or >PN70 (adult). Animals were observed individually in 29-l transparent glass cylindrical jars equipped with standard photocells that were used to measure locomotor activity. Toluene significantly increased activity as compared to air exposure in all groups of male and female rats with the magnitude of locomotor stimulation produced by 4000 ppm toluene being significantly greater for female adults than during any age of adolescence. The results demonstrate that exposure to abuse patterns of high concentrations of toluene through inhalation can alter spontaneous locomotor behavior in rats and that the expression of these effects appears to depend upon the postnatal age of testing and sex of the animal.

    Background Adolescent participation in leisure activities is developmentally beneficial, but certain activities may increase health compromising behaviours, such as tobacco smoking. A limited range of leisure activities has been studied, with little research on out-of-school settings where parental supervision is a potential protective factor. Tobacco smoking is an important, potentially modifiable health determinant, so understanding associations between adolescent leisure activities, parental monitoring, demographic factors and daily smoking may inform preventive strategies. These associations are reported for a New Zealand adolescent sample. Methods Randomly selected schools (n = 145) participated in the 2006 Youth In-depth Survey, a national, biennial study of Year 10 students (predominantly 14-15 years). School classes were randomly selected and students completed a self-report questionnaire in class time. Adjustment for clustering at the school level was included in all analyses. Since parental monitoring and demographic variables potentially confound relations between adolescent leisure activities and smoking, variables were screened before multivariable modelling. Given prior indications of demographic differences, gender and ethnic specific regression models were built. Results and Discussion Overall, 8.5% of the 3,161 students were daily smokers, including more females (10.5%) than males (6.5%). In gender and ethnic specific multivariate analysis of associations with daily smoking (adjusted for age, school socioeconomic decile rating, leisure activities and ethnicity or gender, respectively), parental monitoring exhibited a consistently protective, dose response effect, although less strongly among Māori. Attending a place of worship and going to the movies were protective for non-Māori, as was watching sports, whereas playing team sport was protective for all, except males.

    We examine the association between depressive symptoms and contraceptive method choice among adolescents initiating prescription contraception. This cross-sectional study analyzes baseline data of 220 urban, minority adolescent females (ages 15-19 years) presenting for prescription contraceptive initiation at a comprehensive, free-of-cost, adolescent health center in New York City. All participants met with a health care provider who provided standard contraception counseling before initiating contraception. Each participant then selected a short- or long-acting contraceptive: a 3-month supply of the pill, patch, ring or a medroxyprogesterone acetate depot injection (short-acting), or placement/referral for an intrauterine device (IUD; long-acting). We assess the independent association between contraceptive method selection and symptoms of depression [assessed by the Center for Epidemiological Studies - Depression (CES-D) scale]. Ten percent (n=21/220) of adolescent females selected an IUD. Bivariate analysis revealed that those with elevated levels of depressive symptoms were more likely to select an IUD as compared to those with minimal symptoms (mean CES-D score 20 vs. 13; t=3.052, p=.003). In multivariate logistic regressions, adolescent females had increased odds of selecting an IUD if they reported moderate to severe depressive symptoms (adjusted odds ratio=4.93; confidence interval, 1.53-15.83; p=.007) after controlling for ethnicity/race, education, number of lifetime partners and gravidity. Inner-city, minority adolescents with elevated symptoms of depression who present for prescription contraceptive initiation may be more likely to select an IUD rather than shorter-acting methods. By recognizing adolescent females with depressive symptoms, providers can strategize their approach to effective contraception counseling. Copyright © 2015 Elsevier Inc. All rights reserved.

    Occurrence of temporomandibular disorders (TMDs) and temporomandibular joint (TMJ) osteoarthritis (OA) during adolescence may have interactions with mandibular and dental development. The aim of the present study was to investigate relationships between occurrence of TMD and TMJ OA and extents of dental and skeletal development in juvenile female patients. In total, 95 female adolescents (age range, 11-15 years) were selected. Among them, 15 subjects (control) had no signs of TMD, 39 TMD patients did not have OA (TMDnoOA), 17 TMD patients were at initial stage of TMJ OA (TMJOA), and 27 patients showed progressive stage of TMJ OA (TMJOA). Dental age was estimated by Demirjian's stages used in a previous study with Korean adolescents. Craniofacial parameters and cervical vertebrae maturation (CVM) stages, representing skeletal maturity levels, were measured using lateral cephalograms. The estimated dental age was significantly lower than chronological age in all groups, but CVM differences were not statistically significant. Dental age was the lowest, and differences between the chronological age and estimated dental age were the highest among initial stage of TMJOAs followed by progressive stage of TMJOAs, TMDnoOAs and control and were not associated with CVM stages. Cephalometric parameters revealed significant clockwise rotation of the mandible among the TMJOAs compared with controls and TMDnoOAs and were not associated with CVM stages as well. The juvenile female patients with TMD, particularly TMJ OA, showed retarded dental development, mandibular backward positioning and hyperdivergent facial profiles. The TMJ OA may be associated with retarded dental development but not with skeletal maturations. © 2017 John Wiley & Sons Ltd.

    In Bangladesh, 24 % of the total populations are adolescents. Twelve months intervention was implemented under Demand-Based Reproductive Health Commodity Project (DBRHCP) in two low performing areas: rural Sub-district Nabiganj (population 323,357) and an urban slum in Dhaka city (population 141,912). We evaluated the changes in knowledge of female unmarried adolescents on selected reproductive health issues over the project period in two low performing areas of Bangladesh. A pre-post study design was adopted. Under DBRHCP, interventions were focused on training of government service providers, disseminating behaviour change materials within the targeted communities, and employing community-based health promoters (Community Support Group and Peer Promoters) to foster linkages between the community and providers. All households were enumerated. A baseline survey was conducted during November 2006 to March 2007 and an end-line survey was conducted during November 2008 to March 2009. Eight hundred female unmarried adolescents (12-19 years) were selected independently for each survey from each study area through systematic random sampling, capturing changes over the 12 months intervention period. Data was analyzed using SPSS. A chi-square test was used to assess the changes in knowledge between baseline and end-line among the female unmarried adolescents. Female unmarried adolescents had significantly increased knowledge at the end-line about measures to be taken during menstruation like: using clean and dry cloths. Overall, two-third of female unmarried adolescents knew about Family Planning (FP) methods in both study areas but had significantly increased knowledge on injectables and condoms at the end-line. Overall knowledge on Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDs) was markedly different in the urban and rural areas, but a significantly higher proportion of female unmarried adolescents knew about HIV/AIDs from relatives and

    Motor, cognitive, social and behavioral problems have been found to persist in adolescents born extremely preterm. Leisure participation has been associated with health benefits; however, few studies have explored leisure participation in this population. The aim of this study was to describe leisure participation in adolescents born at ≤29week gestation. Secondary aims were to identify potential differences in participation related to sex, age, motor competence, and cognitive ability, and between adolescents born preterm and their siblings born at term. This cross-sectional study included 128 adolescents (mean age: 16.0years; 67 females) with a mean gestational age of 26.5weeks. All participants, as well as 22 siblings born at term, completed the Children's Assessment of Participation and Enjoyment. Participation levels were highest in social and recreational activities, and lowest in active-physical and skill-based activities. Boys participated in more active-physical activities (p=0.01) and more often (p<0.001) than girls, whereas girls had higher participation levels in social and self-improvement activities (p<0.05) than boys. Older adolescents engaged in more social activities (p=0.01) and more frequently (p=0.002) than younger adolescents. Overall, participants with poor motor and cognitive skills had lower participation levels in active-physical and social activities. Adolescents born preterm participated in fewer recreational activities compared to term-born siblings (p=0.013). Engagement in active-physical and skill-based leisure activities needs to be promoted in boys, and especially in girls with a history of prematurity. Activities should be adapted to sex and individual skill level in order to promote participation. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Ketamine is used by preadolescent and adolescent humans for licit and illicit purposes. The goal of the present study was to determine the effects of acute and repeated ketamine treatment on the unconditioned behaviors and conditioned locomotor activity of preadolescent and adolescent rats. To assess unconditioned behaviors, female and male rats were injected with ketamine (5-40 mg/kg), and distance traveled was measured on postnatal day (PD) 21-25 or PD 41-45. To assess conditioned activity, male and female rats were injected with saline or ketamine in either a novel test chamber or the home cage on PD 21-24 or PD 41-44. One day later, rats were injected with saline and conditioned activity was assessed. Ketamine produced a dose-dependent increase in the locomotor activity of preadolescent and adolescent rats. Preadolescent rats did not exhibit sex differences, but ketamine-induced locomotor activity was substantially stronger in adolescent females than males. Repeated ketamine treatment neither caused a day-dependent increase in locomotor activity nor produced conditioned activity in preadolescent or adolescent rats. The activity-enhancing effects of ketamine are consistent with the actions of an indirect dopamine agonist, while the inability of ketamine to induce conditioned activity is unlike what is observed after repeated cocaine or amphetamine treatment. This dichotomy could be due to ketamine's ability to both enhance DA neurotransmission and antagonize N-methyl-D-aspartate (NMDA) receptors. Additional research will be necessary to parse out the relative contributions of DA and NMDA system functioning when assessing the behavioral effects of ketamine during early ontogeny.

    The goal of this study was to investigate the association of physical activity (PA) and cardiorespiratory fitness with C-reactive protein (CRP) concentration in adolescents. The sample included 386 Portuguese adolescents (n = 207, female), age 12-18 years, assessed in the year 2012. The PA was assessed with the use of accelerometers, and the cardiorespiratory fitness was assessed by the Fitnessgram Pacer test. Blood samples were collected after a 10-hour fasting, and high-sensitivity PCR concentration was further assessed. Significant associations between CRP and cardiorespiratory fitness were found for females (r = -0.313; p < 0.001) and males (r = -0.163; p < 0.05); however, when adjusted by the BMI, the associations remained significant only for females (r = -0.215; p < 0.001). Regarding the association between CRP and PA, no significant associations were found for both genders. Therefore, CRP is apparently negatively associated with cardiorespiratory fitness, with differences between males and females; for females it seems less dependent than BMI.

    Dopamine systems vary through development in a manner that can impact drugs acting on those systems. Dietary factors can also impact the effects of drugs acting on dopamine systems. This study examined whether eating high fat chow alters locomotor effects of cocaine (1-56 mg/kg) in adolescent and adult female rats. Cocaine was studied in rats (n = 6/group) with free access to standard (5.7% fat) or high fat (34.3%) chow or restricted access to high fat chow (body weight matched to rats eating standard chow). After 1 week of eating high fat chow (free or restricted access), sensitivity to cocaine was significantly increased in adolescent and adult rats, compared with rats eating standard chow. Sensitivity to cocaine was also increased in adolescent rats with restricted, but not free, access to high fat chow for 4 weeks. When adolescent and adult rats that previously ate high fat chow ate standard chow, sensitivity to cocaine returned to normal. In adolescent and adult female rats eating high fat chow, but not those eating standard chow, sensitivity to cocaine increased progressively over once weekly tests with cocaine (i.e., sensitization) in a manner that was not statistically different between adolescents and adults. These results show that eating high fat chow alters sensitivity of female rats to acutely administered cocaine and also facilitates the development of sensitization to cocaine. That the type of food consumed can increase drug effects might have relevance to vulnerability to abuse cocaine in the female population.

    Objective To evaluate the impact of contamination, or the presence of child maltreatment in a comparison condition, when estimating the broad, longitudinal effects of child maltreatment on female health at the transition to adulthood. Methods The Female Adolescent Development Study (N = 514; age range: 14–19 years) used a prospective cohort design to examine the effects of substantiated child maltreatment on teenage births, obesity, major depression, and past-month cigarette use. Contamination was controlled via a multimethod strategy that used both adolescent self-report and Child Protective Services records to remove cases of child maltreatment from the comparison condition. Results Substantiated child maltreatment significantly predicted each outcome, relative risks = 1.47–2.95, 95% confidence intervals: 1.03–7.06, with increases in corresponding effect size magnitudes, only when contamination was controlled using the multimethod strategy. Conclusions Contamination truncates risk estimates of child maltreatment and controlling it can strengthen overall conclusions about the effects of child maltreatment on female health.

    Objective. To understand the relationships between participation in different types of leisure time sport activity and adolescent obesity, and how those relationships might differ based on race, gender, and household income. Methods. Data consisted of 6667 students that took part in the 1999 to 2006 National Health and Nutrition Examination Survey. The authors used adjusted Wald tests to examine differences in the prevalence of obesity (body mass index >95th percentile for age and sex) by sport for boys and girls separately. Results. Among adolescent youth age 12 to 19 years, 16.6% of male leisure time sport participants and 15.3% of female sport participants were obese, compared with 23.6% for male nonathlete participant-in-other-activities and 17.0% obesity rate for female nonathlete/participant-in-other-activities. For both males and females, reported participation in leisure time sports decreased between middle school and high school, and this reduction was associated with higher body mass index.

    To examine demographic, behavioral, and physical correlates of body esteem among female adolescents of lower socioeconomic background. Data were collected in a women's health clinic in southeast Texas as part of a larger investigation. A total of 271 female individuals aged 16-21 years completed the Body Esteem Scale (BES), which yields scores for total body esteem, sexual attractiveness, weight concern, and physical condition. Participants answered questions regarding smoking and the presence of acne. Height and weight were measured by a nurse using standard instrumentation and technique. Of the participants, 35% were African-American, 31% white, and 34% Hispanic; and 48% reported an annual household income less than $20,000. The mean body mass index (BMI) was 26.1 (SD = 6.5). Race/ethnicity was associated with total body esteem, sexual attractiveness, weight esteem, and physical condition (all p < .01). African-American participants demonstrated greater body esteem on all scales relative to white participants. Adolescents reporting annual household incomes less than $20,000 (vs. greater) demonstrated higher overall body esteem, sexual attractiveness, and physical condition (all p < .01). Current smokers (vs. non-smokers) reported lower physical condition (p < .01), lower weight concern (p < .05), and lower overall body esteem (p < .02). BMI was associated with weight concern (p < .001) and total body esteem (p = .05). Adolescents reporting acne (vs. not) reported lower scores for total body esteem, sexual attractiveness, and weight concern (all p < .05). Body esteem among adolescent females is affected by demographic, physical, and behavioral variables. Results highlight the importance of measuring multiple dimensions of body esteem.

    For many girls, the onset of puberty that occurs during adolescence marks a time of heightened vulnerability to early pregnancy, with its attendant complications and heightened risk of maternal mortality. National and international forums have recognized the need to address these problems through reproductive health education. This article assesses the reproductive-health-related knowledge and attitudes of female adolescents aged between 14 and 19 years. In addition, the authors assess the effectiveness of a reproductive health education program in improving the related knowledge of female adolescents. The study was conducted on female students in three secondary schools and in the preparatory year at Qassim University (N = 309). A 59-item structured questionnaire was used to test the knowledge and attitudes of all participants regarding reproductive health before and after the intervention program. Data collection was carried out between September and November 2012. A significant increase for the total sample in knowledge regarding puberty and menstruation was observed (p < .001) postintervention. Differences in overall knowledge regarding pregnancy and antenatal care were statistically significant. Knowledge regarding contraceptive intrauterine devices improved from 27.2% preintervention to 67.6% postintervention. This study clearly showed that the reproductive health education program improves knowledge among adolescent girls regarding reproductive health.

    The present study investigated the relationship between regular sport participation (soccer) and vigilance performance. Two groups of male and female adolescents differentiated in terms of their sport participation (athletes, n = 39, and non-athletes, n = 36) took part in the study. In one session, participants performed the Leger Multi-stage fitness test to estimate their aerobic fitness level. In the other session, participants completed the Psychomotor Vigilance Task (PVT) to evaluate their vigilance performance. Perceived arousal prior to the task and motivation toward the task were also measured in the PVT session. The results revealed that athletes had better cardiovascular fitness and showed better performance in the PVT. However, correlation analyses did not show any significant relationship between cardiovascular fitness and performance in the PVT. Athletes showed larger scores in motivation and perceived arousal measures with respect to non-athletes, although, once again, these variables were not correlated with PVT performance. Gender differences were observed only in the Leger test, with males showing greater fitness level than females. The major outcome of this research points to a positive relationship between regular sport participation and vigilance during adolescence. This relationship did not seem to be influenced by gender, perceived arousal, motivation toward the task or cardiovascular fitness. We discuss our results in terms of the different hypotheses put forward in the literature to explain the relationship between physical activity and cognitive functioning.

    School-based extracurricular activity involvement has been associated with lower levels of substance use among adolescents from various populations; however, these associations have only been slightly examined among American Indian (AI) adolescents. Building from various theoretical perspectives, it was hypothesized that AI adolescents' perceived access to and the intensity (i.e., frequency) of participation in extracurricular activities would be associated with lower substance use and less engagement in risky substance use behaviors (i.e., being drunk or high at school, riding/driving with an intoxicated driver, and selling drugs). The moderating influences of sex, age, reservation residence, and metropolitan status also were examined. Data from the 2010 Arizona Youth Survey were analyzed for 5,701 8th, 10th, and 12th grade AI adolescents (49.1% female). The expected protective effects of extracurricular participation were demonstrated, such that high levels of perceived availability and intensity of participation consistently predicted low levels of all outcomes. Some of these associations were moderated by one or more demographic factors, with unique patterns emerging for each behavior. Ultimately, the findings suggest that AI adolescents benefit from the availability of extracurricular activities and intensity of participation in them, but the degree of the effect is contingent upon other individual and contextual characteristics.

  13. Stress responses of adolescent male and female rats exposed repeatedly to cat odor stimuli, and long-term enhancement of adult defensive behaviors.

    In order to characterize the short- and long-term effects of repeated stressor exposure during adolescence, and to compare the effects of using two sources of cat odor as stressor stimuli, male and female adolescent rats (postnatal day (PND) ∼ 38-46) were exposed on five occasions to either a control stimulus, a cloth stimulus containing cat hair/dander, or a section of cat collar previously worn by a cat. Relative to control stimulus exposure, activity was suppressed and defensive behavior enhanced during exposure to either cat odor stimulus (most pervasively in rats exposed to the collar). Only cloth-exposed rats showed elevated levels of corticosterone (CORT), and only after repeated stressor exposure, but interestingly, rats exposed to the collar stimulus during adolescence continued to show increased behavioral indices of anxiety in adulthood. In this group, the time an individual spent in physical contact with a cagemate during the final adolescent exposure was negatively related to stress-induced CORT output in adulthood, which suggests that greater use of social support during adolescent stress may facilitate adult behavioral coping, without necessitating increased CORT release. These findings demonstrate that adolescent male and female rats respond defensively to cat odor stimuli across repeated exposures and that exposure to such stressors during adolescence can augment adult anxiety-like behavior in similar stressful conditions. These findings also suggest a potential role for social behavior during adolescent stressor exposure in mediating long-term outcomes. Copyright © 2012 Wiley Periodicals, Inc.

    Twenty-six female student dancers of Chung-hua school of Art (mean age 17.5 ± 0.5 years) and twenty-five healthy active female collegiate students (mean age 18.1 ± 1.0 years) participated in this study to investigate the effects of dancing exercise on postural stability of adolescent female through a comparison study of two cohorts. The groups were matched in height and weight. Participants were excluded for left-side dominance, sustained lower extremity injury, any known vestibular system dysfunction, uncorrected visual problems, and other neurological conditions. Static and dynamic standing balances were measured by means of Biodex Stability System in six conditions include bilateral, dominant, and nondominant single leg stances with eye-open and eye-closed conditions. To investigate the difference between static and dynamic stabilities, two protocols were performed: the first protocol consisted of four positions including static position, Level 8, Level 4, and Level 1, respectively. They were instructed to maintain a level platform as stably as possible for a period of 30 seconds for each test and given a 30-second rest between tests. The second protocol was descending stability level that was gradually changed from Level 12 to Level 1 for 60 seconds. Balance indices included overall stability index, anterior-posterior stability index (APSI), and medial-lateral stability index. The results of first protocol showed that there were significant differences in overall stability index score between study and control groups at Level 8 with dominant single leg standing in the eye-open condition and the APSI score at Level 8 and at Level 4 with dominant single-leg standing in the eye-closed condition. There was no significant difference in the second protocol. The possible explanation is loss of familiarization adaptation because of level change consequently in both the groups, not step-by-step as in the first protocol study. Furthermore, a positive correlation was

    Refusal skills training was extended to sexually active handicapped female adolescents who lacked an effective refusal strategy. Role-plays for assessment and training were developed using the who, what, when and where of situations which resulted in unwanted intercourse. Refusal skills were trained following the format of rationale, modeling, rehearsal, feedback, and reinforcement. Baseline rates of most target behaviors were quite low. High frequencies of target behaviors were observed as each behavior became the focus of training. Generalization across staff and time was also observed. The skillfulness and effectiveness of the subjects' refusal skills were judged to be improved as a function of training. One-year follow-up showed decreased sexual activity for each girl.

    The aim of this study was to examine the effects of Epstein's TARGET strategies on adolescents' intentions to be physically active and leisure-time physical activity (LTPA) levels. A total of 447 secondary education students (193 females and 254 males), range age 12-17 years, were divided in two groups: control (N = 224) and experimental (N = 223). Epstein's TARGET strategies were applied by especially trained teachers only to the experimental group in their physical education (PE) classes during 12 consecutive weeks. Participants' intentions to be physically active and their LTPA levels were assessed prior to the intervention (pre), at the end of it (post-1) and 3 months after the intervention (post-2). Significant increases were observed only in the experimental group in post-1 and post-2 on both variables. PE interventions based on TARGET strategies seem to be effective increasing adolescents' intentions to be physically active, as well as time spent in LTPA. As most adolescents participate in PE, these interventions could lead to substantial public health benefits. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Many adolescent female cancer patients will survive into their reproductive years. Pediatric oncologists are advised to discuss oncofertility during treatment planning. In this pilot study, 19 adolescent females completed a retrospective survey assessing recall of a fertility discussion, satisfaction with fertility knowledge, and multiple factors that may influence recall, including parental involvement in decision-making. Eleven respondents (58%) remembered a discussion about infertility risk and 9 (47%) about fertility preservation. Most who recalled a discussion were satisfied with their fertility knowledge (10/11, 90.9%). In this study, we validated the feasibility of survey administration and identified trends in oncofertility counseling at our center.

    The purpose of this study was to analyze risk factors for abortion among female teenagers from 12 to 19 years of age in the city of Maceió, Brazil. This is a cross-sectional study, conducted in ten schools. The sample was calculated by considering the number of admissions for postabortion curettage, obtained from the Information System of Hospitalization. Data were obtained through a semi-structured questionnaire divided into three basic blocks of data: sociodemographic, sexual life, and pregnancy/abortion. To analyze the data, the logistic regression model was used. The Forward Method was chosen to set the final model that minimizes the number of variables and maximizes the accuracy of the model. The significant analysis between the dichotomous variables provided eight significant variables. Two of them are protective for abortion: the ages 12-14 years and talking with parents about sex. After the logistic regression, the receipt of support for abortion was the most significant variable of all. The adolescent with an active sexual life, a previous pregnancy, who is married, and has received support for an abortion has a 99.74% probability for an abortion. The results of this study, demonstrating the importance of the group in adolescence, and the statistical significance of having a partner to support and approve the pregnancy appears as a preventive factor for abortion. It shows the importance of support and companionship for adolescent women.

    OBJECTIVE: To study anthropometrical and body composition variables as predictors of risk for metabolic alterations and metabolic syndrome in female adolescents. METHODS: Biochemical, clinical and corporal composition data of 100 adolescents from 14 to 17 years old, who attended public schools in Viçosa, Southeastern Brazil, were collected. RESULTS: Regarding nutritional status, 83, 11 and 6% showed eutrophia, overweight/obesity and low weight, respectively, and 61% presented high body fat percent. Total cholesterol presented the highest percentage of inadequacy (57%), followed by high-density lipoprotein (HDL - 50%), low-density lipoprotein (LDL - 47%) and triacylglycerol (22%). Inadequacy was observed in 11, 9, 3 and 4% in relation to insulin resistance, fasting insulin, blood pressure and glycemia, respectively. The highest values of the fasting insulin and the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) were verified at the highest quartiles of body mass index (BMI), waist perimeter, waist-to-height ratio and body fat percent. Body mass index, waist perimeter, and waist-to-height ratio were the better predictors for high levels of HOMA-IR, blood glucose and fasting insulin. Waist-to-hip ratio was associated to arterial hypertension diagnosis. All body composition variables were effective in metabolic syndrome diagnosis. CONCLUSIONS: Waist perimeter, BMI and waist-to-height ratio showed to be good predictors for metabolic alterations in female adolescents and then should be used together for the nutritional assessment in this age range.

    To determine whether household food insecurity (HFI) is associated with a higher prevalence of excessive weight (EW) in a large random sample of Brazilian female adolescents. Nationally representative cross-sectional study. EW was the outcome variable (BMI ≥ 85th percentile of WHO reference for adolescents aged 15-18 years and BMI ≥ 25 kg/m(2) for those aged 19 years). HFI was measured with the Brazilian Food Insecurity Scale. Associations were measured using crude and adjusted prevalence ratios (PR) with 95 % confidence intervals through Poisson regression models taking into account the complex sampling design. Data were derived from the third wave of the Demographic and Health Survey conducted in 2006-2007, in Brazil. The sample included 1529 female adolescents aged 15-19 years. The prevalence of any level of HFI was 40.8 %, with 26.6 % of households experiencing mild, 9.4 % moderate and 4.8 % severe food insecurity. The overall prevalence of EW was 21.9 % (12.9 % were overweight and 9.0 % obese). EW prevalence among those living in severely, moderately and mildly food-insecure households was 36.8 %, 14.9 % and 16.5 %, respectively (P for the overall association = 0.036). Women living in severely food-insecure households had an increased prevalence of EW compared with their food-secure counterparts (PR = 1.96; 95 % CI 1.18, 3.27; P = 0.007), after adjusting for important confounders. The study suggests that severe but not mild or moderate HFI is independently associated with EW among adolescents residing in Brazil, a middle-income country undergoing the nutrition transition.

    Physical activity, physical fitness and motor competence are important health-related constructs. However, the relationship among them, particularly for children and adolescents, is still unclear. In this study, motor competence (measured by the McCarron Assessment of Neuromuscular Development), pedometer-determined physical activity and physical fitness (aerobic fitness, muscle strength, muscle endurance, flexibility and body composition) were examined in a cohort of 1585 adolescents (771 girls, 814 boys) of mean age 14.06 years. Significant gender differences were observed for all measures except motor competence. Apart from hip and shoulder flexibility, males outperformed females. For both males and females, motor competence was associated with all fitness measures, physical activity was associated only with aerobic fitness and aerobic fitness was associated with physical activity, motor competence, BMI and chest pass. Among males, aerobic fitness was also associated with all other fitness tests. The correlations were, in general, moderate to weak. The results challenge the current focus on physical activity rather than physical fitness as the preferred intervention.

The objective of this study is to detect the pattern and predicting factors of interpersonal violence among adolescent female students in a nursing high school in Cairo. A cross-sectional study was conducted during the academic year 2011-2012 and included a total of 220 students using a self-administered questionnaire. Physical violence exposure at home, school and community among studied adolescents were 65.5, 30.4 and 25.9% respectively. Verbal violence was found in 55, 69 and 60% at home, school and community respectively. Finally 5 and 41.3% of studied students were exposed to sexual violence at home and community respectively. The highest violence exposure score was at school from teachers while the highest score of being violent was mainly towards the community. Multivariate regression analysis for violence scores revealed that younger students, students from urban residence and higher crowding index were significant predictors for total violence exposure and being violent scores. Prevention programmes should be given for all students especially high risk ones (young age, urban residence and high crowdness index families) and their families to address and overcome this problem.

    Positive associations between dog ownership and adult health outcomes have been observed, but research involving youth is lacking. The purpose of this study was to assess the relationship of family dog ownership to adolescent physical activity. Data were collected on dog ownership in 618 adolescent/parent pairs between 9/2006 and 6/2008 and analyzed in 2010. Adolescent physical activity was assessed by ActiGraph accelerometers. Adolescents' mean age was 14.6±1.8 years and 49% were male. White and higher-SES adolescents were more likely to own a dog. In models adjusted for age, puberty, gender, race, total household members, and SES, adolescent physical activity (mean counts·min(-1)day(-1)) remained significantly associated with dog ownership (β=24.3, SE=12.4, p=0.05), whereas the association with minutes of moderate to vigorous physical activity per day became nonsignificant (β=2.2, SE=1.2, p=0.07). No significant results were observed for other adolescent characteristics. Dog ownership was associated with more physical activity among adolescents. Further research using longitudinal data will help clarify the role that dog ownership may have on adolescent physical activity. Copyright © 2011 American Journal of Preventive Medicine.

    This study explored the relationship between the involvement of biological fathers and the sexual risk behaviors and dating violence/victimization and/or perpetration of adolescent girls. The data used in this cross-sectional analysis were drawn from the second wave of the public release of the National Longitudinal Study of Adolescent Health. Only adolescents who reported their biological sex as female, reported a history of being sexually active, and reported having a romantic partner in the previous 18 months were selected (N = 879). This study focused on overall positive sexual behaviors and use of contraception. Structural equation modeling (SEM) was used to best utilize capacity for dealing with latent variables and to test for possible mediation effects. The analysis demonstrated main effects of dating violence and father involvement on sexual behaviors. The more dating violence an adolescent girl experiences, the less likely she is to engage in healthy sexual behaviors. Likewise, the more involvement the biological father has in a woman's life, the more likely she is to engage in positive sexual behaviors. Perceived father involvement was associated with risky sexual behaviors among sexually experienced adolescent girls. Dating violence was directly associated with risky sexual behaviors among sexually experienced adolescent girls, particularly non-White girls. Future studies should use longitudinal models and test theoretically and empirically guided potential mediators. Future studies should also consider father figures such as step-fathers and grandfathers in addition to biological fathers, as having a father figure may be a stronger predictor of adolescent sexual behaviors than having a biological connection. © The Author(s) 2014.

    Objective To (i) compare fracture prevalence in adolescent females with anorexia nervosa (AN) vs. normal-weight controls and (ii) examine whether reductions in areal bone mineral density (aBMD) predict fracture risk in females with AN. Methods 418 females (310 with active AN and 108 normal-weight controls) 12–22 years old were studied cross-sectionally. Lifetime fracture history was recorded by a physician during participant interviews. Body composition and aBMD measurements of the whole body, whole body less head, lumbar spine, and hip were assessed by dual-energy x-ray absorptiometry (DXA), and bone mineral apparent density (BMAD) was calculated for the lumbar spine. Results Participants with AN and normal-weight controls did not differ for chronological age, sexual maturity, or height. The lifetime prevalence of prior fracture was 59.8% higher in those with AN compared to controls (31.0 % versus 19.4 %, p = 0.02), and the fracture incidence rate peaked in our cohort after the diagnosis of AN. Lower aBMD and lumbar BMAD were not associated with a higher prevalence of fracture in the AN or control group on univariate or multivariate analyses. Compared to controls, fracture prevalence was significantly higher in the subgroup of girls with AN who had normal aBMD or only modest reductions of aBMD (Z-scores > −1 or −1.5). Discussion This is the first study to show that the risk of fracture during childhood and adolescence is significantly higher in patients with AN than in normal-weight controls. Fracture prevalence is increased in this cohort of subjects with AN even without significant reductions in aBMD. PMID:24430890

    Background Appalachia is a geographic region with high cervical cancer incidence and mortality rates, yet little is known about human papillomavirus (HPV) vaccination in this region. We determined HPV vaccine coverage among adolescent females from Appalachia, made comparisons to non-Appalachian females, and examined how coverage differs across subregions within Appalachia. Methods We analyzed 2008–2010 data from the National Immunization Survey-Teen (NIS-Teen) for adolescent females ages 13–17 (n=1,951 Appalachian females and n=25,468 non-Appalachian females). We examined HPV vaccine initiation (receipt of at least one dose), completion (receipt of at least three doses), and follow-through (completion among initiators). Analyses used weighted logistic regression. Results HPV vaccine initiation (Appalachian=40.8% vs. non-Appalachian=43.6%; OR=0.92, 95% CI: 0.79–1.07) and completion (Appalachian=27.7% vs. non-Appalachian=25.3%; OR=1.12, 95% CI: 0.95–1.32) were similar between Appalachian and non-Appalachian females. HPV vaccine follow-through was higher among Appalachian females than non-Appalachian females (67.8% vs. 58.1%; OR=1.36, 95% CI: 1.07–1.72). Vaccination outcomes tended to be higher in the Northern (completion and follow-through) and South Central (follow-through) subregions of Appalachia compared to non-Appalachian U.S. Conversely, vaccination outcomes tended to be lower in the Central (initiation and completion) and Southern (initiation and completion) subregions. Conclusions In general, HPV vaccination in Appalachia is mostly similar to the rest of the U.S. However, vaccination is lagging in regions of Appalachia where cervical cancer incidence and mortality rates are highest. Impact Current cervical cancer disparities could potentially worsen if HPV vaccine coverage is not improved in regions of Appalachia with low HPV vaccine coverage. PMID:23136141

    There is a growing recognition of the importance of the out-of-school activities in which adolescents choose to participate. Youth activities vary widely in terms of specific activities and in time devoted to them but can generally be grouped by the type and total duration spent per type. We collected leisure time information using a 17-item leisure time questionnaire in a large sample of same- and opposite-sex adolescent twin pairs (N = 2847). Using both univariate and multivariate genetic models, we sought to determine the type and magnitude of genetic and environmental influences on the allocation of time toward different leisure times. Results indicated that both genetic and shared and nonshared environmental influences were important contributors to individual differences in physical, social, intellectual, family, and passive activities such as watching television. The magnitude of these influences differed between males and females. Environmental influences were the primary factors contributing to the covariation of different leisure time activities. Our results suggest the importance of heritable influences on the allocation of leisure time activity by adolescents and highlight the importance of environmental experiences in these choices.

    We examined the association of physical activity (PA), cardiovascular fitness (CVF) and fatness with total homocysteine (tHcy) concentrations in European adolescents. The present study comprised 713 European adolescents aged 14.8 ± 1.2 y (females 55.3%) from the multicenter HELENA cross-sectional study. PA was assessed through accelerometry, CVF by the 20-m shuttle run test, and body fat by skinfold thicknesses with the Slaughter equation. Plasma folate, cobalamin, and tHcy concentrations were measured. To examine the association of tHcy with PA, CVF, and fatness after controlling for a set of confounders including age, maturity, folate, cobalamin, creatinine, smoking, supplement use, and methylenetetrahydrofolate reductase 677 genotype (CC 47%, CT 43%, TT 10%), bivariate correlations followed by multiple regression models were performed. In the bivariate correlation analysis, tHcy concentrations were slightly negatively correlated (p<0.05) with CVF in females (measured both by stages: r=-0.118 and by VO2max: r=-0.102) and positively with body mass index (r=0.100). However, daily time spent with moderate and vigorous PA showed a weak positive association with tHcy in females (p<0.05). tHcy concentrations showed a tendency to decrease with increasing CVF and increase with increasing BMI in female European adolescents. However, tHcy concentrations were positively associated with moderate and vigorous PA in female European adolescents.

    To evaluate the influence of self-esteem on levels of body dissatisfaction among adolescent females. A group of 397 adolescents aged 12 to 17 years were enrolled in the study. The Body Shape Questionnaire (BSQ) was applied to assess body dissatisfaction. The Rosenberg Self-Esteem Scale was used to assess self-esteem. Weight, height, and skinfold thickness were also measured. These anthropometric data were controlled in the statistical analyses. The multiple regression model indicated influence of "positive self-esteem" (R(2)=0.16; p=0.001) and "negative self-esteem" (R(2)=0.23; p=0.001) subscales on the BSQ scores. Univariate analysis of covariance demonstrated differences in BSQ scores (p=0.001) according to groups of self-esteem. It was concluded that self-esteem influenced body dissatisfaction in adolescent girls from Juiz de Fora, MG. Copyright © 2014 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    This study investigated if motor proficiency (MP) in preschool age associate with physical activity (PA) in adolescence. In 2004, the Bruininks-Oseretsky Test of Motor Proficiency-Short Form (BOTMP-SF) (7) was administered to 413 children, aged 4-6 years, who were classified to MP groups according to their BOTMP-SF total score (TS). In 2014, the PA of 106 former participants (47 boys, 59 girls) was measured with Omron pedometers. MP [three (high; above average; average)] × gender (two) ANOVA and Bonferroni tests were computed on average of steps/week. A significant interaction between the two factors was revealed (F = 15.27, p < .001, η 2 =.153), indicating that MP influenced male and female PA differently. Only in average MP group, males presented higher PA than females, whereas there were no differences between the two genders in the higher MP groups. Moreover, the only significant difference in PA among male groups was that between high and above average MP groups, while in females there were significant differences among all groups. High MP at preschool age positively associated with the PA in adolescence, especially in females. Emphasis on the development of proficient young movers might be beneficial for lifelong PA.

    To evaluate the association between levels of physical activity and perception of the social and built environmental in adolescents from Northeastern Brazil. The sample comprised 2874 adolescents aged 14 to 19 years (57.8% females) enrolled in private or public secondary schools in the municipality of João Pessoa, Northeastern Brazil. Level of physical activity was measured by questionnaire. Perception of environmental characteristics was measured by means of fifteen questions rated on four-point Likert-type scales ranging from 1 ("strongly disagree") to 4 ("strongly agree"). The association between physical activity and perception of environmental characteristics was investigated using multivariate binary logistic regression. Multivariate analysis showed that adolescents living in neighborhoods where other adolescents were physically active (68.7% vs. 60.1%, OR=1.20; 95%CI: 1.05-1.56, among boys only) or who lived close to places they liked to frequent (71.8% vs. 53.4%, OR=1.96; 95%CI: 1.40-2.78 among boys; and 42.0% vs. 32.3% OR=1.33; 95%CI: 1.10-1.74 among girls) were more likely to be physically active. Adolescents with positive perceptions of certain environmental characteristics were more likely to be physically active. Environmental characteristics may relate differently to levels of physical activity among boys and girls. Published by Elsevier Inc.

    Body image satisfaction significantly influences self-esteem in female adolescents. Increased reports of lowered satisfaction in this population have raised concerns regarding their compromised self-esteem. This research study, therefore, sought to identify a culturally significant moderator of the association between body image satisfaction and self-esteem in Thai female adolescents. Orientation toward self-compassion, found to be particularly high in Thailand, was examined. A total of 302 Thai female undergraduates from three large public and private universities in the Bangkok metropolitan area responded to a set of questionnaires, which measured demographic information, body image satisfaction, self-compassion, and self-esteem. Data were analyzed using correlation and multiple regression analyses. Self-compassion was tested as a moderator of the relationship between body image satisfaction and self-esteem. Although its effect was relatively small, self-compassion significantly moderated the positive relationship between body image satisfaction and self-esteem. The relationship became less stringent for those with high self-compassion. The cultivation of self-compassion was recommended in female adolescents. In addition to moderating the association between body image satisfaction and self-esteem, the benefits to health and well-being of generalizing this cultivation are discussed.

    Purpose: For decades, researchers have proclaimed the positive psychosocial benefits of participation in physical activity. However, recent meta-analyses of the literature have found infrequent and inconclusive empirical support for the link between physical activity and psychosocial well-being. In this study, we use data from a longitudinal study to explore the links between participation in physical activity and global self-esteem among girls from childhood into early adolescence and the direction of this relationship. Methods: Participants included 197 non-Hispanic white girls. Girls' participation in physical activity and their global self-esteem were assessed when they were 9, 11, and 13 years old. Panel regression was used to assess the lagged effect of physical activity on self-esteem and the lagged effect of self-esteem on physical activity, controlling for family socioeconomic status (SES) and girls' body mass index (BMI). Results: A significant lagged effect of physical activity on self-esteem was identified. Specifically, higher physical activity at ages 9 and 11 years predicted higher self-esteem at ages 11 and 13 years respectively, controlling for covariates. Positive effects of physical activity on self-esteem were most apparent at age 11 and for girls with higher BMI. No support was gained for the lagged effect of self-esteem on physical activity. Conclusions: Results suggest that participating in physical activity can lead to positive self-esteem among adolescent girls, particularly for younger girls and those at greatest risk of overweight. These findings highlight the necessity of promoting physical activity among adolescent girls as a method of fostering positive self-worth. PMID:18023784

    The relationship between Australian adolescents' participation in extracurricular activities and their self-concepts was investigated. A total of 1489 adolescents (56% female; mean age 13.8 years) completed measures of social self-concept, academic self-concept, and general self-worth, and reported on their extracurricular activity participation. In general, participation in any type of extracurricular activity was associated with a higher social and academic self-concept, and general self-worth, compared to no participation. Adolescents who participated in both sports and non-sports also reported a more positive social self-concept and general self-worth, compared to those who only participated in one of the activity types. This research provides support for extracurricular activities as a context facilitative of positive self-concept, and demonstrates the importance of a mixed participation profile for an adolescent's self-concept.

    Adolescents, particularly African American adolescents, are at high risk for sexually transmitted infections (STIs). The association between psychosocial factors and risky sexual behavior has been well established. However, only a small number of studies have examined the relationship between depressive symptomatology among African American female adolescents, specifically over time. The present study examined depressive symptoms as a predictor of risky sexual behavior, sexual communication, and STIs longitudinally among African American female adolescents between the ages 15 and 21. Binary generalized estimating equation models were conducted assessing the impact of depressive symptoms at baseline on risky sexual behavior and STIs over six- and 12-months follow-up. Age, intervention group, and baseline outcome measures were entered as covariates. The results indicated that high levels of depressive symptoms predicted no condom use during last sexual encounter and multiple sexual partners over six-months follow-up. Depressive symptoms also predicted having a main partner with concurrent partners, high fear of communication about condoms, and sex while high on alcohol or drugs over six- and 12-months follow-up. These findings could be used to inform HIV/STI prevention intervention programs and clinicians providing regular health care maintenance to African American female adolescents engaging in risky sexual behavior. © 2011 Taylor & Francis

    Paediatric obesity is a public health concern worldwide as it can track into adulthood and increase the risk of adult morbidity and mortality. While the aetiology of obesity is multi-factorial, the roles of diet and physical activity are controversial. Thus, the purpose of this study was to report on the differences in energy intake, diet composition, time spent doing physical activity and energy expenditure among underweight (UW), normal weight (NW) and at-risk of overweight (OW) Malaysian adolescents (317 females and 301 males) aged 11-15 years. This was a cross-sectional study with 6,555 adolescents measured for weights and heights for body mass index (BMI) categorisation. A total of 618 subjects were randomly selected from each BMI category according to gender. The subjects' dietary intake and physical activity were assessed using self-reported three-day food and activity records, respectively. Dietary intake components included total energy and macronutrient intakes. Energy expenditure was calculated as a sum of energy expended for basal metabolic rate and physical activity. Time spent (in minutes) in low, medium and high intensity activities was also calculated. The OW adolescents had the highest crude energy intake and energy expenditure. However, after adjusting for body weight, the OW subjects had the lowest energy intake and energy expenditure (p-value is less than 0.001). The study groups did not differ significantly in time spent for low, medium and high intensity activities. Macronutrient intakes differed significantly only among the girls where the OW group had the highest intakes compared to UW and NW groups (p-value is less than 0.05). All study groups had greater than 30 percent and less than 55 percent of energy intake from fat and carbohydrate, respectively. The data suggested that a combination of low energy expenditure adjusted for body weight and high dietary fat intake may be associated with overweight and obesity among adolescents. To

Brain structure and cognitive function in female subjects with adolescent-onset anorexia nervosa assessed at long-term follow-up were studied in comparison with healthy female subjects, and associations with clinical outcome were investigated. Sixty-six female subjects (aged 21.3 +/- 2.3 years) who had a diagnosis of adolescent-onset anorexia nervosa and treated 6.5 +/- 1.7 years earlier in a tertiary care hospital and 42 healthy female control subjects (aged 20.7 +/- 2.5 years) were assessed. All participants underwent a clinical examination, magnetic resonance brain scan, and cognitive evaluation. Clinical data were analyzed first as a function of weight recovery (n = 14, <85% ideal body weight; n = 52, >or=85% ideal body weight) and as a function of menstrual status (n = 18, absent/irregular menses; n = 29, oral contraceptive pill; n = 19, regular menses). Group comparisons were made across structural brain volumes and cognitive scores. Compared with control subjects, participants with anorexia nervosa who remained at low weight had larger lateral ventricles. Twenty-four-hour urinary free-cortisol levels were positively correlated with volumes of the temporal horns of the lateral ventricles and negatively correlated with volumes of the hippocampi in clinical participants. Participants who were amenorrheic or had irregular menses showed significant cognitive deficits across a broad range of many domains. Female subjects with adolescent-onset anorexia nervosa showed abnormal cognitive function and brain structure compared with healthy individuals despite an extended period since diagnosis. To our knowledge, this is the first study to report a specific relationship between menstrual function and cognitive function in this patient

    To determine whether the level of physical activity or physical fitness (i.e., aerobic capacity and muscle strength) in Spanish adolescents influences lipid and metabolic profiles. From a total of 2859 Spanish adolescents (age 13.0-18.5 years) taking part in the AVENA (Alimentación y Valoración del Estado Nutricional en Adolescentes) study, 460 (248 male, 212 female) were randomly selected for blood analysis. Their level of physical activity was determined by questionnaire. Aerobic capacity was assessed using the Course-Navette test. Muscle strength was evaluated using manual dynamometry, the long jump test, and the flexed arm hang test. A lipid-metabolic cardiovascular risk index was derived from the levels of triglycerides, low-density lipoprotein cholesterol (LDLC), high-density lipoprotein cholesterol (HDLC), and glucose. No relationship was found between the level of physical activity and lipid-metabolic index in either sex. In contrast, there was an inverse relationship between the lipid-metabolic index and aerobic capacity in males (P=.003) after adjustment for physical activity level and muscle strength. In females, a favorable lipid-metabolic index was associated with greater muscle strength (P=.048) after adjustment for aerobic capacity. These results indicate that, in adolescents, physical fitness, and not physical activity, is related to lipid and metabolic cardiovascular risk. Higher aerobic capacity in males and greater muscle strength in females were associated with lower lipid and metabolic risk factors for cardiovascular disease.

    This paper analyzes real-life moral dilemmas of Israeli city and kibbutz adolescents. The contribution of Gilligan's theory to our knowledge of adolescent moral development as originally conceived by Kohlberg is emphasized. It is suggested that Kohlberg's view of the adolescent as a moral philosopher limits the understanding of the moral development of female adolescents, who use both care and justice in their self-descriptions within existing relationships.

    This report summarizes the experience of 61 female adolescents recruited through a private adolescent family planning clinic, and 183 9th through 12th-grade adolescents recruited from a private suburban high school regarding their experiences with dating relationships, sexual communication skills, and psychological status. The samples were predominantly white and middle to upper income. Perceptions of interpersonal communication skills were analyzed according to gender, clinic versus school, and history of sexual coercion. The adolescents were generally confident that they could assert their own preferences and stand up to other regarding sexual issues with the exception of the small group of high school males reporting having had experienced sexual coercion. This group (N = 20) expressed difficulty in talking to their partners about safer sex, getting their partner(s) to listen to them, or turning down alcohol or drugs prior to having sex. These boys were also more likely to report missing classes or having other kinds of trouble with school, to be concerned about use of alcohol and drugs, and about feeling unpopular. None of the female groups had this profile of communication and emotional problems. Implications for preventive education programming on interpersonal skills and sexuality are considered.

    Eating disorders were first described in black females in South Africa in 1995. A subsequent community based study of eating attitudes amongst adolescent females in an urban setting suggested that there would be increasing numbers of sufferers from within the black community. The current study sought to extend these findings using a larger, more representative urban sample. The results support those of the preliminary study. The underlying basis for the emerging phenomenon is discussed PMID:16633453

    For women, the nature and range of experiences during the high school years take on special significance, since it is during this period that they usually weigh their various roles and adjust their levels of aspirations accordingly. If the high school environment is successful in reducing the discrepancy between what are often viewed as conflicting roles, adolescent females may place greater emphasis on achievement. It is within this context that the present paper explored the differential benefits of single-sex and coeducational schooling. The issue explored is not whether one is preferable for females; rather, the concern here is how each of these settings influences both achievement and personal fulfillment.

    Most US adolescents do not meet guidelines of at least 60 daily minutes of moderate- to vigorous-intensity physical activity. In addition, sedentary behaviors among this age group are of increasing concern. This study examined the association of movement behaviors with cardiovascular fitness among US adolescents. Data from the 2012 NHANES National Youth Fitness Survey were used to assess the association of movement behaviors (physical activity, sedentary time, screen time) with cardiovascular fitness among adolescent males and females. Multiple logistic regressions were used to test the independent and interactive effects of movement behaviors on cardiovascular fitness. Among females, physical activity was directly associated with cardiovascular fitness; no significant association was observed between sedentary behaviors and CVF. Among males, sedentary time moderated the relationship between physical activity and cardiovascular fitness, such that a significant, direct association was only observed among those with high sedentary time (OR: 5.01; 95% CI: 1.60, 15.70). Results from this cross-sectional analysis suggest that among female US adolescents, physical activity, but not sedentary behavior, is associated with cardiovascular fitness. Among males, the interaction between physical activity and sedentary time seems to be important for cardiovascular fitness. Longitudinal studies are warranted to confirm these findings.

    Obesity and lack of physical activity are fast becoming a concern among Malaysian adolescents. This study aims to assess physical activity levels among Malaysian adolescents and investigate the association between physical activity levels and body composition such as body mass index (BMI), waist circumference (WC) and percentage of body fat. 1361 school-going 13 year old multi-ethnic adolescents from population representative samples in Malaysia were involved in our study. Self-reported physical activity levels were assessed using the validated Malay version of the Physical Activity Questionnaire for Older Children (PAQ-C). Height, weight, body fat composition and waist circumference (WC) were measured. Data collection period was from March to May 2012. 10.8% of the males and 7.4% of the females were obese according to the International Obesity Task Force standards. A majority of the adolescents (63.9%) were physically inactive. There is a weak but significant correlation between physical activity scores and the indicators of obesity. The adjusted coefficient for body fatness was relatively more closely correlated to physical activity scores followed by waist circumference and lastly BMI. This study demonstrates that high physical activity scores were associated with the decreased precursor risk factors of obesity. Copyright © 2014. Published by Elsevier Inc.

    Objective: To evaluate the influence of self-esteem on levels of body dissatisfaction among adolescent females. Methods: A group of 397 adolescents aged 12 to 17 years were enrolled in the study. The Body Shape Questionnaire (BSQ) was applied to assess body dissatisfaction. The Rosenberg Self-Esteem Scale was used to assess self-esteem. Weight, height, and skinfold thickness were also measured. These anthropometric data were controlled in the statistical analyses. Results: The multiple regression model indicated influence of "positive self-esteem" (R2=0.16; p=0.001) and "negative self-esteem" (R2=0.23; p=0.001) subscales on the BSQ scores. Univariate analysis of covariance demonstrated differences in BSQ scores (p=0.001) according to groups of self-esteem. Conclusion: It was concluded that self-esteem influenced body dissatisfaction in adolescent girls from Juiz de Fora, MG. PMID:25479855

    To evaluate the impact of contamination, or the presence of child maltreatment in a comparison condition, when estimating the broad, longitudinal effects of child maltreatment on female health at the transition to adulthood. The Female Adolescent Development Study (N = 514; age range: 14-19 years) used a prospective cohort design to examine the effects of substantiated child maltreatment on teenage births, obesity, major depression, and past-month cigarette use. Contamination was controlled via a multimethod strategy that used both adolescent self-report and Child Protective Services records to remove cases of child maltreatment from the comparison condition. Substantiated child maltreatment significantly predicted each outcome, relative risks = 1.47-2.95, 95% confidence intervals: 1.03-7.06, with increases in corresponding effect size magnitudes, only when contamination was controlled using the multimethod strategy. Contamination truncates risk estimates of child maltreatment and controlling it can strengthen overall conclusions about the effects of child maltreatment on female health. © The Author 2015.

    Purpose Left ventricular (LV) enlargement has been linked to sudden cardiac death among young athletes. This study aimed to model the effect of long-term incessant endurance training on LV dimensions in female adolescent runners. Methods Japanese female adolescent competitive distance runners (n = 36, age: 15 years, height: 158.1 ± 4.6 cm, weight: 44.7 ± 6.1 kg, percent body fat: 17.0 ± 5.2%) underwent echocardiography and underwater weighing every 6 months for 3 years. Since the measurement occasions varied across subjects, multilevel analysis was used for curvilinear modeling of changes in running performance (velocities in 1500 m and 3000 m track race), maximal oxygen uptake (VO2max), body composition, and LV dimensions. Results Initially, LV end-diastolic dimension (LVEDd) and LV mass were 47.0 ± 3.0 mm and 122.6 ± 15.7 g, respectively. Running performance and VO2max improved along with the training duration. The trends of changes in fat-free mass (FFM) and LVEDd were similarly best described by quadratic polynomials. LVEDd did not change over time in the model including FFM as a covariate. Increases in LV wall thicknesses were minimal and independent of FFM. LV mass increased according to a quadratic polynomial trend even after adjusting for FFM. Conclusions FFM was an important factor determining changes in LVEDd and LV mass. Although running performance and VO2max were improved by continued endurance training, further LV cavity enlargement hardly occurred beyond FFM gain in these adolescent female runners, who already demonstrated a large LVEDd.

    Estimate sexual activity among Congolese adolescents in Brazzaville and appreciate the influence of sociocultural and economic factors on sexual behaviour. Data were collected from 900 adolescents (389 males and 511 females) aged 10-19 years in the seven urban areas of Brazzaville. These subjects were randomly recruited by a two stage sampling. The data were gathered by an anonymous face-to-face questionnaire. Relative risk estimations were calculated for early or first sexual intercourse, multiple sexual partnerness and safe sex. A total of 474 respondents indicated that they were sexually active. Females were more sexually active, 270 compared with 204 males (p<0.05). The mean early age of coital debut was 14.6 years (S.D.=1.7 years). Early intercourse (before 14 years) was found in 73 males and 39 females (p<0.001). Multiple sexual partnerness was found in 81.3% of males, while the frequency of females was 51.1%. Risk factors for pregnancy and multiple sexual partnerness were unemployment mother, non school situation, early puberty and non sexual education. In contrast, regular religious activity was recognized as factor that had significant protection impact on sexual activity. The total use ratio of the condom was estimated at 42.2% in males. More females (41.7%) were using Ogino method of contraception. In addition, 102 females (36.8%) claimed to have already a pregnancy and the mean age was 16.1 years (S.D.=1.2 years). In 64.7% of these cases, teenagers chose the abortion as solution of an unwanted pregnancy. After the birth of a child, it was reported that 82.4% of adolescents gave up with school. Our results show the importance of problems associated to sexual activity among Congolese adolescents in Middle Africa. These data should be taken into account when planning the prevention of risk of sexual behaviours among adolescents.

  6. Consequences of Adolescent Exposure to the Cannabinoid Receptor Agonist WIN55,212-2 on Working Memory in Female Rats.

    Marijuana is a prevalent illicit substance used by adolescents, and several studies have indicated that adolescent use can lead to long-term cognitive deficits including problems with attention and memory. However, preclinical animal studies that observe cognitive deficits after cannabinoid exposure during adolescence utilize experimenter administration of doses of cannabinoids that may exceed what an organism would choose to take, suggesting that contingency and dose are critical factors that need to be addressed in translational models of consequences of cannabinoid exposure. Indeed, we recently developed an adolescent cannabinoid self-administration paradigm in male rats, and found that prior adolescent self-administration of the cannabinoid receptor agonist WIN55,212-2 (WIN) resulted in improved working memory performance in adulthood. In addition, the doses self-administered were not as high as those that are found to produce memory deficits. However, given known sex differences in both drug self-administration and learning and memory processes, it is possible that cannabinoid self-administration could have different cognitive consequences in females. Therefore, we aimed to explore the effects of self-administered vs. experimenter-administered WIN in adolescent female rats on adult cognitive function. Female rats were trained to self-administer WIN daily throughout adolescence (postnatal day 34-59). A control group self-administered vehicle solution. The acute effects of adolescent WIN self-administration on memory were determined using a short-term spatial memory test 24 h after final SA session; and the long-term effects on cognitive performance were assessed during protracted abstinence in adulthood using a delayed-match-to-sample working memory task. In a separate experiment, females were given daily intraperitoneal (IP) injections of a low or high dose of WIN, corresponding to self-administered and typical experimenter-administered doses, respectively, or

    Adolescent participation in academic/extracurricular activities is related to fewer diagnoses of sexually transmitted infections during adolescence. The role parents play in motivating participation in such activities is unclear. This mixed-methods study explored parental influences on academic/extracurricular activity participation, and the relationship of such participation to adolescents' future aspirations and sexual behavior, over a 4-year period. We utilized semistructured interviews with 28 White and Asian American adolescents (age 17-19) and event history calendar self-reports of activities, part-time jobs, and sexual behaviors. Data triangulation was used to integrate qualitative and quantitative data. Increased participation was correlated with abstinence and later sexual onset. Many adolescents reported that parents were reluctant to talk with them about sexual risks and instead preferred to keep them busy and ensure that they had the "right" friends. Adolescents endorsed the parental strategy of keeping them busy with activities. Findings and implications for school nursing practice are discussed.

    Purpose As more young female patients with cancer survive their primary disease, concerns about reproductive health related to primary therapy gain relevance. Cancer therapy can often affect reproductive organs, leading to impaired pubertal development, hormonal regulation, fertility, and sexual function, affecting quality of life. Methods The Children's Oncology Group Long-Term Follow-Up Guidelines for Survivors of Childhood, Adolescent, and Young Adult Cancer (COG-LTFU Guidelines) are evidence-based recommendations for screening and management of late effects of therapeutic exposures. The guidelines are updated every 2 years by a multidisciplinary panel based on current literature review and expert consensus. Results This review summarizes the current task force recommendations for the assessment and management of female reproductive complications after treatment for childhood, adolescent, and young adult cancers. Experimental pretreatment as well as post-treatment fertility preservation strategies, including barriers and ethical considerations, which are not included in the COG-LTFU Guidelines, are also discussed. Conclusion Ongoing research will continue to inform COG-LTFU Guideline recommendations for follow-up care of female survivors of childhood cancer to improve their health and quality of life.

    2007-05-01

    To determine if urinary symptoms or urinary tract infections (UTI) were associated with sexually transmitted infections (STI) and which history, clinical, and laboratory findings could distinguish these infections in symptomatic women. A cross-sectional sample of 296 sexually active females aged 14-22 years attending a hospital-based teen health center or emergency department were recruited. Genitourinary symptoms, medical and sexual history, and urinalysis results were recorded. STI was defined as a vaginal swab positive for Trichomonas vaginalis or urine nucleic acid amplification test positive for Neisseria gonorrheae or Chlamydia trachomatis. A urine culture with >10,000 colonies of a single pathogen was considered a positive UTI. In the full sample, prevalence of UTI and STI were 17% and 33%, respectively. Neither urinary symptoms nor UTI was significantly associated with STI. Further analyses are reported for the 154 (51%) with urinary symptoms: Positive urine leukocytes, more than one partner in the last three months and history of STI predicted STI. Urinalysis results identified four groups: (1) Normal urinalysis-67% had no infection; (2) Positive nitrites or protein-55% had UTI; (3) Positive leukocytes or blood-62% had STI; and (4) Both nitrites/protein and leukocytes/blood positive-28% had STI and 65% had UTI. Those without a documented UTI were more likely to have trichomoniasis than those with a UTI, and 65% of those with sterile pyuria had STI, mainly trichomoniasis or gonorrhea. Adolescent females with urinary symptoms should be tested for both UTI and STIs. Urinalysis results may be helpful to direct initial therapy.

    Anxiety disorders and nicotine use are significant contributors to global morbidity and mortality as independent and comorbid diseases. Early-life stress, potentially via stress-induced hypothalamic-pituitary-adrenal axis (HPA) dysregulation, can exacerbate both. However, little is known about the factors that predispose individuals to the development of both anxiety disorders and nicotine use. Here, we examined the relationship between anxiety-like behaviors and nicotine responses following adolescent stress. Adolescent male and female BALB/cJ mice were exposed to either chronic variable social stress (CVSS) or control conditions. CVSS consisted of repeated cycles of social isolation and social reorganization. In adulthood, anxiety-like behavior and social avoidance were measured using the elevated plus-maze (EPM) and social approach-avoidance test, respectively. Nicotine responses were assessed with acute effects on body temperature, corticosterone production, locomotor activity, and voluntary oral nicotine consumption. Adolescent stress had sex-dependent effects on nicotine responses and exploratory behavior, but did not affect anxiety-like behavior or social avoidance in males or females. Adult CVSS males exhibited less exploratory behavior, as indicated by reduced exploratory locomotion in the EPM and social approach-avoidance test, compared to controls. Adolescent stress did not affect nicotine-induced hypothermia in either sex, but CVSS males exhibited augmented nicotine-induced locomotion during late adolescence and voluntarily consumed less nicotine during adulthood. Stress effects on male nicotine-induced locomotion were associated with individual differences in exploratory locomotion in the EPM and social approach-avoidance test. Relative to controls, adult CVSS males and females also exhibited reduced corticosterone levels at baseline and adult male CVSS mice exhibited increased corticosterone levels following an acute nicotine injection.

    This study aimed to investigate the effects of both past and current physical activity and media use on women's body image. A sample of 144 female undergraduate students completed measures of current physical activity, media use and body image, as well as providing retrospective reports of their physical activity participation and media usage during childhood and adolescence. Regression analyses showed that childhood experiences of physical activity and media use predicted adult body-image concerns more strongly than current activities. It was concluded that early experiences of both physical activity and media use during childhood and adolescence play an important role in the development of adult women's body image.

    2013-02-01

    Grounded in Grych and Fincham's cognitive appraisal theory, this study examined whether female emerging adults' (N = 216) recalled sibling warmth moderated the relationship between exposure to inter-parental conflict in adolescence and their current depression. Findings indicated that sibling warmth moderated the relationship between the intensity and frequency of inter-parental conflict and depression, but not inter-parental conflict resolution. Compared to female emerging adults who reported lower sibling warmth, those who reported higher sibling warmth in the face of greater intensity and higher frequency of inter-parental conflict during adolescence had lower depression. The important role of siblings for youth from conflicted homes was highlighted.

    Anxiety disorders are more likely to occur in women than in men, usually emerge during adolescence and exhibit high comorbidity with alcohol use disorders (AUD). Adolescents with high levels of anxiety or heightened reactivity to stress may be at-risk for developing AUD. An approach to analyze if high levels of inborn anxiety predict greater ethanol drinking is to assess the latter variable in subjects classified as high- or low-anxiety responders. The present study assessed ethanol drinking in adolescent, female Wistar, rats classified as high-, low- or average-anxiety responders and exposed or not to restraint stress (RS, Exp. 1). Classification was made through a multivariate index derived from testing anxiety responses in an elevated plus maze and a light-dark box tests. RS was applied after animals had been initiated to ethanol drinking. Intake of sweetened ethanol was unaffected by level of anxiety response. Adolescents with high levels of inborn anxiety exhibited significantly higher intake of unsweetened ethanol than counterparts with standard levels of anxiety, yet this effect was inhibited by RS exposure. Experiment 2 assessed FOS immunoreactivity after RS. Stress induced a significant increase in FOS immunoreactivity at the paraventricular nucleus, yet this effect was unaffected by level of anxiety response. Female adolescents with high levels of basal anxiety may be at-risk for exhibiting increased predisposition for ethanol intake and preference.

    Intrauterine growth restriction (IUGR) is a risk factor for memory impairment and emotional disturbance during growth and adulthood. However, this risk might be modulated by environmental factors during development. Here we examined whether exposing adolescent male and female rats with thromboxane A2-induced IUGR to social defeat stress (SDS) affected their working memory and anxiety-like behavior in adulthood. We also used BrdU staining to investigate hippocampal cellular proliferation and BrdU and NeuN double staining to investigate neural differentiation in female IUGR rats. In the absence of adolescent stress, IUGR female rats, but not male rats, scored significantly lower in the T-maze test of working memory and exhibited higher anxiety-like behavior in the elevated-plus maze test compared with controls. Adolescent exposure to SDS abolished these behavioral impairments in IUGR females. In the absence of adolescent stress, hippocampal cellular proliferation was significantly higher in IUGR females than in non-IUGR female controls and was not influenced by adolescent exposure to SDS. Hippocampal neural differentiation was equivalent in non-stressed control and IUGR females. Neural differentiation was significantly increased by adolescent exposure to SDS in controls but not in IUGR females. There was no significant difference in the serum corticosterone concentrations between non-stressed control and IUGR females; however, adolescent exposure to SDS significantly increased serum corticosterone concentration in control females but not in IUGR females. These results demonstrate that adolescent exposure to SDS improves behavioral impairment independent of hippocampal neurogenesis in adult rats with IUGR. Copyright © 2015 Elsevier Inc.

    The authors compared cognitive-behavioral therapy (CBT) and psychodynamic therapy (PDT) for the treatment of bulimia nervosa (BN) in female adolescents. In this randomized controlled trial, 81 female adolescents with BN or partial BN according to the DSM-IV received a mean of 36.6 sessions of manualized disorder-oriented PDT or CBT. Trained psychologists blinded to treatment condition administered the outcome measures at baseline, during treatment, at the end of treatment, and 12 months after treatment. The primary outcome was the rate of remission, defined as a lack of DSM-IV diagnosis for BN or partial BN at the end of therapy. Several secondary outcome measures were evaluated. The remission rates for CBT and PDT were 33.3% and 31.0%, respectively, with no significant differences between them (odds ratio [OR] = 0.90, 95% CI = 0.35-2.28, p = .82). The within-group effect sizes were h = 1.22 for CBT and h = 1.18 for PDT. Significant improvements in all secondary outcome measures were found for both CBT (d = 0.51-0.82) and PDT (d = 0.24-1.10). The improvements remained stable at the 12-month follow-up in both groups. There were small between-group effect sizes for binge eating (d = 0.23) and purging (d = 0.26) in favor of CBT and for eating concern (d = -0.35) in favor of PDT. CBT and PDT were effective in promoting recovery from BN in female adolescents. The rates of remission for both therapies were similar to those in other studies evaluating CBT. This trial identified differences with small effects in binge eating, purging, and eating concern.

    Back pain is common in adolescents which has been associated with carrying a bag. However, there is little research examining the effects of bag style in female adolescents. The aim of the study was to investigate the effects of different bag conditions on muscle activity of the trapezius, erector spinae and latissimus dorsi muscles in female university students during walking. Twelve female university students walked on a treadmill for 5 minutes at 1.1 m/s during five conditions; control, 1 strapped rucksack, 2 strapped rucksack, ipsilateral shoulder strap and contralateral shoulder strap, each containing 10% bodyweight. Electromyography for the trapezius, erector spinae and latissimus dorsi was recorded for the last 30 s of each condition. Two-way ANOVA and paired t-tests were used to identify differences between right and left muscles and between bag conditions. Results showed that muscle activity of the left trapezius was significantly higher than the right trapezius during the 1 strap rucksack condition. For the left trapezius, the 2 strapped rucksack and the control condition had significantly lower muscle activity compared to the 1 strapped rucksack and the ipsilateral shoulder strap. For the left erector spinae muscle, there was significantly greater muscle activity when wearing the contralateral shoulder strap compared to the control. For the right erector spinae, significantly lower muscle activity was observed when wearing the 2 strapped rucksack compared to the ipsilateral shoulder strap and contralateral shoulder strap. There were no significant differences in muscle activity of the latissimus dorsi muscles between any of the bag conditions. These findings suggest that a two strapped rucksack should be used when carrying loads to reduce spinal muscle activity which may, in turn, reduce reports of back pain in female adolescents.

    Background Adverse life events have been associated with gambling and substance use as they can serve as forms of escapism. Involvement in gambling and substance use can also place individuals in adversely stressful situations. Objectives To explore potential male-female differences in the association between addictive behavior and adverse life events among an urban cohort of adolescents. Methods The study sample comprised of 515 adolescent participants in a randomized prevention trial. With self-reported data, four addictive behavior groups were created: Non-Substance Users and Non-Gamblers, Substance Users Only, Gamblers Only, and Substance Users and Gamblers. Multinomial logistic regression analyses with interaction terms of sex and adverse life events were conducted. Results Adverse life events and engaging in at least one addictive behavior were common for both sexes. Substance Users and Gamblers had more than twice the likelihood of Non-Substance Users and Non-Gamblers to experience any event as well as events of various domains (i.e., relationship, violence, and instability). Neither relationship nor instability events’ associations with the co-occurrence of substance use and gambling significantly differed between sexes. Conversely, females exposed to violence events were significantly more likely than similarly exposed males to report the co-occurrence of substance use and gambling. Conclusion Findings from the current study prompt future studies to devote more attention to the development of effective programs that teach adaptive coping strategies to adolescents, particularly to females upon exposure to violence.

    The purpose of this study was to evaluate the effects of systematic health education on female adolescents' knowledge of dysmenorrhea, menstrual attitudes, and dysmenorrhea-related self-care behaviors. Through the research process, a dysmenorrheal self-care pamphlet for female adolescents was developed. The study used a quasi-experimental intervention with a nonequivalent-control group design. Three vocational nursing schools were requested to participate in this study: one was assigned to the experimental group and two were assigned to the control group. Female students who had experienced dysmenorrheic cramps two or more times during the last 6 months since the interview were recruited for the study. There were 218 subjects randomly assigned to an experimental group, and 237 subjects to a control group. Intervention consisted of a three-session health education program in which the experimental group was split up into six smaller groups. Data were collected before, 2 weeks after, and 4 months after the intervention. Results revealed a significant increase in the experimental group members' dysmenorrhea-related knowledge and self-care behavior, but not in their attitudes. The findings of this study can serve as a guide to healthcare providers who want to design an effective systematic menstrual health education program for female adolescents.

    Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and body mass index (BMI). Socioeconomically and racially/ethnically diverse adolescents (N = 2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the Eating and Activity in Teens 2010 study. BMI was measured by research staff. Participants' mean age was 14.6 (standard deviation = 2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school. BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders. Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents' safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    We examined sexual orientation disparities in physical activity, sports involvement, and obesity among a population-based adolescent sample. We analyzed data from the 2012 Dane County Youth Assessment for 13,933 students in grades 9 through 12 in 22 Wisconsin high schools. We conducted logistic regressions to examine sexual orientation disparities in physical activity, sports involvement, and body mass index among male and female adolescents. When we accounted for several covariates, compared with heterosexual females, sexual minority females were less likely to participate in team sports (adjusted odds ratio [AOR] = 0.44; 95% confidence interval [CI] = 0.37, 0.53) and more likely to be overweight (AOR = 1.28; 95% CI = 1.02, 1.62) or obese (AOR = 1.88; 95% CI = 1.43, 2.48). Sexual minority males were less likely than heterosexual males to be physically active (AOR = 0.62; 95% CI = 0.46, 0.83) or to participate in team sports (AOR = 0.26; 95% CI = 0.20, 0.32), but the 2 groups did not differ in their risk of obesity. Sexual orientation health disparities in physical activity and obesity are evident during adolescence. Culturally affirming research, interventions, and policies are needed for sexual minority youths.

  7. The female athlete triad.

    PubMed

    Kazis, Keren; Iglesias, Elba

    2003-02-01

    The female athlete triad is a syndrome consisting of disordered eating, amenorrhea, and osteoporosis. The syndrome is increasing in prevalence as more women are participating in sports at a competitive level. Behaviors such as intense exercise or disordered eating patterns can lead to dysregulation of the hypothalamic-pituitarian-ovarian (HPO) axis, resulting in amenorrhea. Hypothalamic amenorrhea can lead to osteoporosis and increased fracture risk. Adolescents may particularly be at risk because it is during this crucial time that females attain their peak bone mass. Prevention of the female athlete triad through education and identification of athletes at risk may decrease the incidence of long-term deleterious consequences. Treatment of the female athlete triad is initially aimed at increasing caloric intake and decreasing physical activity until there is resumption of normal menses. Treatment of decreased bone mineral density and osteoporosis in the adolescent population, however, is controversial, with new treatment modalities currently being investigated in order to aid in the management of this disorder.

    To examine the association between tanning bed use and weight concerns, health risk behaviors, and peer influence. The Growing Up Today Study (GUTS) is an ongoing prospective cohort study of adolescents established in 1996. In 1999, a total of 6,373 adolescent females ages 12-18 (offspring of participants in the Nurses Health Study 2) completed the survey. Almost nine percent (8.6%) of the adolescent girls had used a tanning bed 1-9 times and an additional 5.4% had used tanning beds at least 10 times in the past year (frequent users). Logistic regression models revealed that frequent tanning bed use was associated with being highly concerned about weight (OR = 1.5, 95%CI = 1.1, 2.0), frequently dieting to lose weight (OR = 1.5, 95%CI = 1.1, 2.0), using laxatives or vomiting to control weight (OR = 3.6; 95%CI = 2.2-5.8), having friends who placed a lot of importance on being thin (OR = 2.6; 95%CI = 1.3-5.1), smoking cigarettes (OR=1.7, 95%CI = 1.1, 2.6), binge drinking (OR = 2.1, 95%CI = 1.3, 3.1), using recreational drugs (OR = 3.0; 95%CI = 2.4, 3.8), and trying to look like females in the media (sometimes/pretty much: OR = 1.3, 95%CI = 1.0, 1.8). Frequent tanning bed use among adolescent females is associated with a range of health risk behaviors. This effect may be mediated by peer influence and a desire to look like other females in the media. Multi-pronged approaches, particularly those that target attitudes of young females, are needed to combat increased use of tanning beds.

    An inconsistent relationship between physical activity and neck/shoulder pain (NSP) in adolescents has been reported in the literature. Earlier studies may be limited by not assessing physical activity in sufficient detail. The aim of this study was to comprehensively examine the association between NSP and the level and nature of physical activity, and type of sedentary activity in adolescents. A cross-sectional analysis using data from 924 adolescents in the Western Australian Pregnancy Cohort (RAINE) study was performed. Complete data were available for 643 adolescents (54.6% female) at the 14-year follow-up. Physical activity was measured using a detailed self-report electronic activity diary requiring participants to input details of all physical activities over the day in segments of 5 minutes for a one-week period. Physical activity levels were categorised as: sedentary, light, moderate, or vigorous based on metabolic energy equivalents. Nature of activity was determined by assigning each activity to categories based on the amount of movement (static/dynamic) and the main posture assumed for the activity (standing/sitting/lying). Type of sedentary activity was characterised by exposure time to watching TV, using a computer, and reading. Logistic regression was used to explore the association between NSP and activity. Females reported a higher prevalence of lifetime, 1-month and chronic NSP than males (50.9 vs 41.7%, 34.1 vs 23.5%, and 9.2 vs 6.2% respectively). No consistent, dose-response relationship was found between NSP and the level, nature, and type of physical activity. Self-reported one month and lifetime NSP prevalence in adolescents is not related to the level or intensity of physical activity or the type of sedentary activity over a one week period.

    Adolescent females with patellofemoral pain (PFP) have localized (around the knee) and distal (tibialis anterior muscle) hyperalgesia assessed by decreased pressure pain thresholds (PPT). This may have implications for treating PFP as both localized and central pain mechanisms may contribute to the manifestations of pain. The objective of this study was to compare the change in localized and distal hyperalgesia among female adolescents with PFP deeming themselves recovered compared with those not recovered 3 months after patient education with or without exercise therapy. This is an ancillary analysis of a cluster randomized controlled trial investigating the effect of patient education with or without exercise therapy on self-reported recovery in 121 adolescents with PFP. PPTs were measured at 4 sites around the knee and on tibialis anterior in a random subsample of 57 female adolescents. Changes in localized and distal hyperalgesia from baseline to follow-up were compared with self-reported recovery. Adolescents were categorized as recovered if they rated themselves as "completely recovered" or "strongly recovered" on a 7-point Likert scale. Thirty-nine adolescents (68%) were available for follow-up at 3 months and 10 adolescents reported being recovered. Recovered adolescents had a 68 kPa (95% CI, 1, 136; P=0.047) larger improvement in PPT around the knee and a 76 kPa (95% CI, -29, 181; P=0.16) nonsignificant improvement in PPT on the tibialis anterior compared with adolescents not recovered. Female adolescents with PFP who rated themselves as recovered had a larger reduction in localized hyperalgesia compared with those not recovered.

    Oligomenorrhea in active adolescent females of normal weight is presumed to be related to hypoestrogenism secondary to physical activity and decreased fat mass. We hypothesized that active adolescents with oligomenorrhea would have lower estrogen levels than normal controls with similar levels of cardiovascular fitness. Twenty healthy participants between the ages of 16 and 20 years were recruited at least 2 years postmenarche. Adolescents reporting fewer than 9 cycles a year (n = 6) were compared to 14 controls with monthly menstrual cycles. Histories of eating disorder, hirsutism, severe acne, depression, or amenorrhea were cause for exclusion. Body composition and bone density were measured by total body dual x-ray absorpitometry. Cardiovascular fitness was evaluated by measuring oxygen consumption during exercise. Control subjects were matched by age, body mass index (BMI), and fitness level. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, progesterone, and estradiol were obtained. Statistical analysis was performed using SAS 9.1. Cardiovascular fitness in both groups was within normal limits for age. No significant differences in BMI, estradiol concentrations, or bone density were found, but trunk fat mass was lower in adolescents with oligomenorrhea who also reported more frequent exercise. Testosterone concentrations and LH/FSH ratios were significantly higher in participants with irregular menstrual cycles (P = 0.0018 and <0.001, respectively). Adolescents with oligomenorrhea were leaner, yet they had higher testosterone levels and a greater LH/FSH ratio than their BMI-matched, cyclic counterparts. We hypothesize that, in active adolescents of normal weight, elevated androgen and LH concentrations are linked to ovarian dysfunction, which can masquerade as exercise-induced oligomenorrhea.

    Objective The aim of this study is to investigate psychological barriers (illness perceptions, insulin beliefs, and coping strategies) to optimal insulin therapy among adolescents with type 1 diabetes (T1D), with a specific focus on gender differences and mode of treatment (insulin pump vs pen). Methods A total of 105 males and females (12–20 years) participated in this study. The Brief Illness Perception Questionnaire, the Beliefs about Medicines Questionnaire, and the Adolescent Coping Orientation for Problem Experiences were completed. Additionally, diabetes clinical data were collected by the Norwegian Childhood Diabetes Registry. Results Females had significantly more negative illness perceptions than males on all dimensions (p<0.05), with moderate-to-large effect sizes. Regarding insulin beliefs, females scored significantly higher than males on insulin concern (p<0.001), indicating more concerns about insulin. There were no significant gender differences on perceptions of insulin necessity. Finally, females scored significantly higher on the coping strategies being social and solving family problems (p<0.01), indicating more positive coping among females than males for these subscales. In terms of treatment mode, the only statistically significant difference in the psychological aspects was for the illness perception treatment control, with patients using insulin pen reporting more negative perceptions on this dimension than patients using insulin pump. Conclusions Addressing psychological aspects may be a clinically important supplement to standard somatic T1D care. The consistent finding of gender differences across the psychological measures implies that a tailored treatment approach for males and females with T1D may be warranted. PMID:27403325

    Physical activity in adolescence may contribute to the development of healthy adult lifestyles, helping reduce chronic disease incidence. However, definition of the optimal amount of physical activity in adolescence requires addressing a number of scientific challenges. This article reviews the evidence on short- and long-term health effects of adolescent physical activity. Systematic reviews of the literature were undertaken using a reference period between 2000 and 2004, based primarily on the MEDLINE/PubMed database. Relevant studies were identified by examination of titles, abstracts and full papers, according to inclusion criteria defined a priori. A conceptual framework is proposed to outline how adolescent physical activity may contribute to adult health, including the following pathways: (i) pathway A--tracking of physical activity from adolescence to adulthood; (ii) pathway B--direct influence of adolescent physical activity on adult morbidity; (iii) pathway C--role of physical activity in treating adolescent morbidity; and (iv) pathway D - short-term benefits of physical activity in adolescence on health. The literature reviews showed consistent evidence supporting pathway 'A', although the magnitude of the association appears to be moderate. Thus, there is an indirect effect on all health benefits resulting from adult physical activity. Regarding pathway 'B', adolescent physical activity seems to provide long-term benefits on bone health, breast cancer and sedentary behaviours. In terms of pathway 'C', water physical activities in adolescence are effective in the treatment of asthma, and exercise is recommended in the treatment of cystic fibrosis. Self-esteem is also positively affected by adolescent physical activity. Regarding pathway 'D', adolescent physical activity provides short-term benefits; the strongest evidence refers to bone and mental health.

    Using data from the Korea Youth Risk Behavior Web-based Survey, this study seeks to investigate associations of suicide attempts with family, individual, and behavioral factors on the basis of gender. Among male adolescents, those who did not live with their parents, who had poor subjective academic achievement, depression, experiences of smoking and sexual coitus, drug abuse, suicidal ideation and plans were more likely to attempt suicide. Among the female adolescents, those who did not live with their parents, had depression, low self-rated health, experiences of drug abuse and sexual coitus, and expressed unhappiness, suicidal ideation and suicide plans were more likely to attempt suicide. Thus, the development of a suicide prevention program for Korean adolescents requires different approaches for males and females.

    This study reports six HR-HPV types’ infection prevalence discriminated by species and multiple infection in unvaccinated Colombian female adolescents, as well as some factors modulating the risk of infection. HPV DNA for six high-risk viral types was identified in cervical samples taken from 2,134 12–19 year-old females using conventional generic and type-specific PCR. Binomial logistical regression analysis was used for modelling HR-HPV infection and multiple infection risk. The interaction between variables in a stepwise model was also included in such analysis. Viral DNA was detected in 48.97% of the females; 28.52% of them had multiple infections, HPV-16 being the most frequently occurring type (37.44%). Cytological abnormality prevalence was 15.61%. Being over 16 years-old (1.66: 1.01–2.71 95%CI), white ethnicity (4.40: 1.16–16.73 95%CI), having had 3 or more sexual partners (1.77: 1.11–2.81 95%CI) and prior sexually-transmitted infections (STI) (1.65: 1.17–2.32 95%CI) were associated with a greater risk of HPV infection. Having given birth was related to a higher risk of infection by A7 species and antecedent of abortion to less risk of coinfection. Where the females in this study came from also influenced the risk of infection by A7 species as female adolescents from the Andean region had a lower risk of infection (0.42: 0.18–0.99 95%CI). The presence of factors related to risky sexual behaviour in the study population indicated that public health services should pay special attention to female adolescents to modify the risk of infection by high-risk HPV types and decrease their impact on this age group.

    Leisure-time physical activity is essential for healthy and physically active life; however, this domain of physical activity is less common in developing countries. Information on leisure time physical activity and sedentary behaviour among Nepalese population is not available. The study was carried out to assess leisure time physical activity and sedentary behaviour among high school adolescents and identify the associated factors in Nepal. A cross-sectional descriptive study was carried out in Banke district, Nepal in 2013 among higher secondary school students using self-administered questionnaire based on International Physical Activity Questionnaire. A sample of 405 students, 178 females and 227 males, of the age-group 15 to 20 years from seven schools were included in the study. Multivariate logistic regression analysis was carried out to identify factors associated with participation in leisure time physical activity and sedentary behaviour. Engagement of female in leisure time physical activity was lower but mean time spent on sitting per day was higher. Students who walked to school and have playground/parks near home, younger females (OR = 3.09, 95% CI: 1.18-8.08), females living in nuclear families (OR: 2.16, 95% CI: 1.01-4.62) and males who cycled to school (OR: 8.09, 95% CI: 2.35-27.80) and have provision of extra-curricular activities (OR: 2.49, 95% CI: 1.04-5.97) were more likely to be engaged in leisure time physical activity. On the other hand, students who did not have playground in school and lived in rural areas were more likely to sit for more than 6 hours a day. Likewise, male students of private school (OR: 6.41, 95% CI: 2.89-14.21), who used vehicle to reach school (OR: 5.90, 95% CI: 1.26-27.75) and have no provision of extra-curricular activities (OR: 2.98, 95% CI: 1.09-8.07) had longer sitting time. Difference in leisure time physical activity and sedentary behaviour was found among male and female school adolescents. Interventions

    Adolescence is a crucial period for the development of adaptive emotion regulation strategies. Despite the fact that structural maturation of the prefrontal cortex during adolescence is often assumed to underlie the maturation of emotion regulation strategies, no longitudinal studies have directly assessed this relationship. This study examined whether use of cognitive reappraisal strategies during late adolescence was predicted by (i) absolute prefrontal cortical thickness during early adolescence and (ii) structural maturation of the prefrontal cortex between early and mid-adolescence. Ninety-two adolescents underwent baseline and follow-up magnetic resonance imaging scans when they were aged approximately 12 and 16 years, respectively. FreeSurfer software was used to obtain cortical thickness estimates for three prefrontal regions [anterior cingulate cortex; dorsolateral prefrontal cortex (dlPFC); ventrolateral prefrontal cortex (vlPFC)]. The Emotion Regulation Questionnaire was completed when adolescents were aged approximately 19 years. Results showed that greater cortical thinning of the left dlPFC and left vlPFC during adolescence was significantly associated with greater use of cognitive reappraisal in females, though no such relationship was evident in males. Furthermore, baseline left dlPFC thickness predicted cognitive reappraisal at trend level. These findings suggest that cortical maturation may play a role in the development of adaptive emotion regulation strategies during adolescence. © The Author (2014).

    This is the second report of a multinational project undertaken in 1988 by the International Round Table for the Advancement of Counseling that sought, among other things, to compare and contrast the reported problems, coping strategies, and help-seeking behavior of 2129 male and 2307 female adolescents from a total of three different socioeconomic backgrounds in each of 16 countries (Australia, Brazil, Canada, Greece, Hong Kong, India, Israel, Japan Kuwait, the Netherlands, the Philippines, China, Puerto Rico, Turkey, the US, and Venezuela) and from a "classless" background in Russia. The first report described the study and research methodology and cited preliminary findings that 1) problems and coping strategies tended to be universal and age-related; 2) impoverished subjects from Brazil, India, the Philippines, and Venezuela had more problems than any other adolescents; 3) problems were usually related to school, family, and identity rather than to sexuality; and 4) the most common coping strategy was individual problem-solving. This report compares male/female identification of up to three problems that cause worry, response to such problems, and help-seeking behavior. All adolescents cited problems in school, identity, and family. Males and females reported similar coping strategies and showed a strong dependence on individual coping strategies. Both males and females choose personal friends and family members as those most likely to help with problems. Males exhibited a higher percentage of problems related to school and a lower percentage of family problems. Russian adolescents reported more problems relating to altruism than any other group, especially males. These results imply that strong similarities exist for males and females, and the findings are worrisome in that problems related to sexuality were not cited. Counselors should expect the concerns of adolescents to be developmentally related and to overwhelm gender differences.

    The current study investigated: (a) the relationships of exposure to the Adolescent Community Reinforcement Approach (A-CRA) with reductions in substance use, illegal activity, and juvenile justice system involvement in adolescents diagnosed with a substance use disorder, and (b) the pathways by which reductions in the target behaviors were achieved. This study is a secondary data analysis of longitudinal data from a large-scale implementation effort for A-CRA. The sample consisted of 1,467 adolescents who presented to substance use treatment and reported past-year engagement in illegal activity. Participants had an average age of 15.8 years (SD = 1.3) and were 25% female, 14% African American, 29% Hispanic, 35% Caucasian, 16% mixed ethnicity, and 6% other ethnicity. Path analyses provided support that participation in A-CRA had a significant, direct association with reduced substance use; a significant, indirect association with reduced illegal activity through reductions in substance use; and a significant indirect association with reduced juvenile justice system involvement through reductions in both substance use and illegal activity. In addition, post hoc analyses using a bootstrapping strategy provided evidence that reductions in substance use partially mediated the relationship between A-CRA and illegal activity.

    Physical activity (PA) is closely linked with child and youth health, and active travel may be a solution to enhancing PA levels. Activity spaces depict the geographic coverage of one's travel. Little is known about activity spaces and PA in adolescents. To explore the relation between adolescent travel (using a spatial measure of activity space size) and daily moderate-to-vigorous PA (MVPA), with a focus on school days. In Fall 2012, we used Global Positioning Systems to manually identify trips and generate activity spaces for each person-day; quantified by area for 39 students (13.8±0.6 years, 38% female) attending high school in urban Downtown Vancouver, Canada. We assessed the association between activity space area and MVPA using multi-level regression. We calculated total, school-day and trip-based MVPA for each valid person-day (accelerometry; ≥ 600 min wear time). On school days, students accrued 68.2 min/day (95% CI 60.4-76.0) of MVPA. Daily activity spaces averaged 2.2 km 2 (95% CI 1.3-3.0). There was no association between activity space size and school-day MVPA. Students accrued 21.8 min/day (95% CI 19.2-24.4) of MVPA during school hours, 19.4 min/day (95% CI 15.1-23.7) during travel, and 28.3 min/day (95% CI 22.3-34.3) elsewhere. School and school travel are important sources of PA in Vancouver adolescents, irrespective of activity space area covered.

    Despite the alarming increase in the prevalence of depression during adolescence, particularly among female adolescents, the pathophysiology of depression in adolescents remains largely unknown. Event-related potentials (ERPs) provide an ideal approach to investigate cognitive-affective processes associated with depression in adolescents, especially in the context of negative self-referential processing biases. In this study, healthy (n = 30) and depressed (n = 22) female adolescents completed a self-referential encoding task while ERP data were recorded. To examine cognitive-affective processes associated with self-referential processing, P1, P2, and late positive potential (LPP) responses to negative and positive words were investigated, and intracortical sources of scalp effects were probed using Low Resolution Electromagnetic Tomography (LORETA). Additionally, we tested whether key cognitive processes (e.g., maladaptive self-view, self-criticism) previously implicated in depression related to ERP components. Relative to healthy female subjects, depressed females endorsed more negative and fewer positive words, and free recalled and recognized fewer positive words. With respect to ERPs, compared to healthy female adolescents, depressed adolescents exhibited greater P1 amplitudes following negative words, which was associated with a more maladaptive self-view and self-criticism. In both early and late LPP responses, depressed females showed greater activity following negative versus positive words, whereas healthy females demonstrated the opposite pattern. For both P1 and LPP, LORETA revealed reduced inferior frontal gyrus activity in response to negative words in depressed versus healthy female adolescents. Collectively, these findings suggest that the P1 and LPP reflect biased self-referential processing in female adolescents with depression. Potential treatment implications are discussed.

    Media's prevailing thin-body ideal plays a vital role in adolescent girls' body image development, but the co-occurring impact of peer feedback is understudied. The present study used functional magnetic resonance imaging (fMRI) to test media imagery and peer feedback combinations on neural activity related to thin-body ideals. Twenty-four healthy female late adolescents rated precategorized body sizes of bikini models (too thin or normal), directly followed by ostensible peer feedback (too thin or normal). Consistent with prior studies on social feedback processing, results showed increased brain activity in the dorsal medial prefrontal cortex (dmPFC)/anterior cingulate cortex (ACC) and bilateral insula in incongruent situations: when participants rated media models' body size as normal while peer feedback indicated the models as too thin (or vice versa). This effect was stronger for girls with lower self-esteem. A subsequent behavioral study (N = 34 female late adolescents, separate sample) demonstrated that participants changed behavior in the direction of the peer feedback: precategorized normal sized models were rated as too thin more often after receiving too thin peer feedback. This suggests that the neural responses upon peer feedback may influence subsequent choice. Our results show that media-by-peer interactions have pronounced effects on girls' body ideals.

    Human papillomavirus (HPV) vaccination remains underused in the United States, and few population-level studies on effectiveness exist. We examined trends in rates of genital warts diagnoses and HPV vaccination rates (defined as receipt of 1 or more vaccine doses) among low-income and minority adolescents between 2004 and 2013. Data were obtained from a database containing de-identified medical record information including all outpatient visits to an urban medical center and 6 affiliated community health centers. International Classification of Diseases, Ninth Revision codes were used to determine genital warts diagnoses. We estimated annual rates of genital warts for each period for females and males using an interrupted time-series Poisson regression model. As HPV vaccination rates in low-income, minority adolescents rose from 0% to 59% (females) and 0 to 41% (males) between 2004 and 2013, genital warts rates decreased from 3.5% (females) and 3.6% (males) to 1.5% (females) and 2.9% (males). Rates of genital warts decreased significantly for both females and males from the prevaccination to the postvaccination periods (P < 0.05 for both comparisons). Genital warts rates for males began to decrease after the introduction of female vaccination and continued to decrease after male vaccination was introduced. Introduction of HPV vaccination correlated with lower rates of genital warts among a cohort of low-income and minority adolescents. Rates of genital warts began to decrease in females and males following the introduction of female vaccination and continued to fall after the introduction of male vaccination, indicating that male vaccination may confer additional benefit to both males and females over herd immunity alone, especially when vaccination rates are suboptimal.

    To highlight the perceived personal, social, and environmental barriers to healthy eating and physical activity among Arab adolescents. A multistage stratified sampling method was used to select 4698 students aged 15-18 years (2240 males and 2458 females) from public schools. Seven Arab counties were included in the study, namely, Algeria, Jordan, Kuwait, Libya, Palestine, Syria, and the United Arab Emirates. Self-reported questionnaire was used to list the barriers to healthy eating and physical activity facing these adolescents. It was found that lack of information on healthy eating, lack of motivation to eat a healthy diet, and not having time to prepare or eat healthy food were the main barriers to healthy eating among both genders. For physical activity, the main barriers selected were lack of motivation to do physical activity, less support from teachers, and lack of time to do physical activity. In general, females faced more barriers to physical activity than males in all countries included. There were significant differences between males and females within each country and among countries for most barriers. Intervention programmes to combat obesity and other chronic noncommunicable diseases in the Arab world should include solutions to overcome the barriers to weight maintenance, particularly the sociocultural barriers to practising physical activity.

    Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis is a marked feature of anorexia nervosa. Using a modified version of the activity-based animal model of anorexia nervosa, we examine whether factors known to affect HPA axis activity influence the development of activity-based anorexia (ABA). Male and female rats were subjected to maternal separation or handling procedures during the first two postnatal weeks and tested in a mild version of the ABA paradigm, comprised of 2-hr daily running wheel access followed by 1-hr food access, either in adolescence or adulthood. Compared to handled females, maternally separated females demonstrated greater increases in wheel running and a more pronounced running-induced suppression of food intake during adolescence, but not in adulthood. In contrast, it was only in adulthood that wheel running produced more prolonged anorexic effects in maternally separated than in handled males. These findings highlight the interplay between early postnatal treatment, sex of the animal, and developmental age on running, food intake, and rate of body weight loss in a mild version of the ABA paradigm.

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

    Neglecting to take account of the underlying context or type of physical activity (PA) that underpins overall involvement has resulted in a limited understanding of adolescents' PA participation. The purpose of the present research was to identify male and female adolescents' leisure time PA patterns and examine whether psychological processes derived from self-determination theory differ as a function of the pattern of PA undertaken. Nine hundred ninety-five students (61.2% females, 38.8% males; M age = 13.72 years, SD = 1.25) from eight secondary schools in Dublin, Ireland completed a physical activity recall 7 day diary and measures of intrinsic motivation, competence, relatedness, autonomy and autonomy support. Based on the diary five binary indicators of physical activity were derived reflecting recommended levels of MVPA on a minimum of 3 days, at least three sessions of non-organized physical activity (e.g. jog), team sport, individual sport, and organized non-sport physical activity (e.g. dance). Latent class analysis was used to identify subgroups of adolescents that engaged in similar patterns of physical activity. Profiles of physical activity participation were subsequently compared on motivational characteristics using Kruskal-Wallis tests. Latent class analysis revealed six distinct classes for girls (Organized Run/Swim & Dance/Gym; Organized Dance; Leisure Active Team Sport; Active Individual Sport; Walk/Run/Outdoor games; Non-Participation) and five for boys (Leisure Active Gym; Leisure Active Individual Sport; Active Team Sport; Active Mixed Type; Non-Participation). Significant differences were found between the classes. Girls characterized by participation in team or individual sport, and boys represented by team sport participation demonstrated significantly higher self-determined motivational characteristics relative to other profiles of physical activity. This research offers a nuanced insight into the underlying type of activities that

    Elevé is a fundamental dance movement practiced routinely by dance students and serving as an integral component of screening in dance. It consists of ankle plantar flexion (PF) movement and is considered to be a frequent cause of foot and ankle injuries among dancers, with adolescent female dance students being at greatest risk for such injuries. Therefore, gaining additional knowledge regarding elevé functional range of motion (ROM) and inter-leg weightbearing distribution (WBD) properties among adolescent dance students is warranted for pedagogic, screening, injury prevention, and rehabilitation purposes. The aims of this study were three-fold: 1. to report and compare dance-specific, functional kinematic (ankle PF maximum angle and ankle PF ROM), kinetic (inter-leg WBD), and self-reported level of difficulty (balance, muscular force, and concentration) properties of repeated and static elevé among adolescent female dance students; 2. to look for correlations between elevé properties and participants' demographics (age, height, weight, dance experience, and leg dominance); and 3. to describe the relationships between the two kinematic properties in both elevé tasks. Twenty-three adolescent female dance students (mean age 13.57 ± 0.50 years) were measured while performing two elevé tasks: 10 repetitions ("repeated elevé task") and 10 consecutive seconds hold ("static elevé task"). Data regarding ankle motion and WBD were collected and analyzed using three-dimensional motion capture and two force plates. The data gained from this study expand our current understanding of elevé dance movement and may contribute to clinical relevancy and applicability of screening procedures being conducted in pre-professional dance settings. This may help to identify adolescent dance students with the potential to undertake a career in professional dance as well as to investigate the parameters associated with risk of ankle injuries in this population.

    The high injury incidence during match-play in female adolescent football is a major concern. In football, males and females play matches with the same football size. No studies have investigated the effect of football size on injury incidence in female adolescent football. Thus, the aim of the present study was to investigate the effects of introducing a lighter, smaller football on the injury pattern in female adolescent football. We conducted a pilot cluster randomized controlled trial including 26 football teams representing 346 adolescent female football players (age 15-18 years). The teams were randomized to a new lighter, smaller football (INT, N.=12 teams) or a traditional FIFA size 5 football (CON, N.=14 teams) during a full match-season. Acute time-loss injuries and football-exposure during match-play were reported weekly by text-message questions and verified subsequently by telephone interview. In total, 46 acute time-loss injuries were registered (5 severe injuries), yielding an incidence rate of 15.2 injuries per 1000 hours of match-play (95% CI: 8.5-27.2) in INT and 18.6 injuries per 1000 hours of match-play (95% CI: 14.0-24.8) in CON. The estimated 22% greater injury incidence rate risk (IRR: 1.22 [95% CI: 0.64-2.35]) in the CON group was not significant. With an IRR of 1.22, a future RCT main study would need to observe 793 acute time-loss injuries during match-play, in order to have a power of 80%. A large-scaled RCT is required to definitively test for beneficial or harmful effects of a lighter, smaller football in adolescent female football.

    This study aims to investigate whether experiences of offline sexual coercion are associated with adolescent females’ involvement in different types of sexting behaviors. It draws on data from 450 ethnically diverse female adolescents with an average age of 19.02 years (SD = 0.74) who were originally recruited in southeast Texas. The participants were asked about their experiences with sexual coercion, and their engagement in sexting behavior (i.e., sending, requesting, and being asked for a sext, and receiving a sext without giving permission). Logistic regressions were used to analyze these relationships, while controlling for age, ethnicity, education level, living situation, and sexting behaviors in the year prior of the study. Offline sexual coercion was significantly associated with sending and being asked for a naked image, as well as receiving a naked image without giving permission. The results suggest that sexting could function as an online extension of offline forms of sexual coercion. PMID:27814493

    Data on menstrual experiences and their impact on quality of life among women in developing countries are scant. The aim of this study was to assess the prevalence of dysmenorrhoea among adolescent girls in Sidon city and suburbs, Lebanon, and to explore its possible relationship with menstrual experience. In a cross-sectional design, 389 post-menarcheal schoolgirls aged 13-19 years were selected using a cluster random sampling method. Of these 161 (41.4%) were regularly or sometimes absent from school due to menstrual problems and 289 (74.3%) experienced dysmenorrhoea. Nevertheless only 7.3% of the girls had consulted a physician about dysmenorrhoea. Three-quarters of these young women (75.2%) had scores indicating negative menstrual experience based on the Menstrual Experience and Behavior Questionnaire. Significant predictors of dysmenorrhoea were negative menstrual experience, younger age of girl, longer duration of bleeding and longer cycle length. Better reproductive health educational programmes focusing on menstruation are needed for female adolescents.

    Objective Over 15 million adolescents, many at high risk for pregnancy, use emergency departments (ED) in the United States annually, but little is known regarding reasons for failure to use contraceptives in this population. The purpose of this study was to identify the barriers to and enablers of contraceptive use among adolescent females using the ED and determine their interest in an ED-based pregnancy prevention intervention. Study Design We conducted semi-structured, open-ended interviews with females in an urban ED. Eligible females were 14-19 years old, sexually active, presenting for reproductive health complaints, and at risk for pregnancy, defined as non-use of effective (per the World Health Organization) contraception. Interviews were recorded, transcribed, and coded based on thematic analysis. Enrollment continued until no new themes emerged. A modified Health Belief Model guided the organization of the data. Results Participants (n=14) were predominantly Hispanic (93%), insured (93%), and in a sexual relationship (86%). The primary barrier to contraceptive use was perceived health risk, including effects on menstruation, weight, and future fertility. Other barriers consisted of mistrust in contraceptives, ambivalent pregnancy intentions, uncertainty about the future, partner's desire for pregnancy, and limited access to contraceptives. Enablers of past contraceptive use included the presence of a school-based health clinic and clear plans for the future. All participants were receptive to ED-based pregnancy prevention interventions. Conclusions The identified barriers and enablers influencing hormonal contraceptive use can be used to inform the design of future ED-based adolescent pregnancy prevention interventions.

    Adolescents living in orphanages are at a disadvantage with respect to mental health. The aim of this study was to assess the distribution of psychological symptoms and their association with the level of physical activity (PA) in adolescents living in orphanages. The study group consisted of 13-16-year-old adolescents (N=166) living in orphanages in Ankara, Turkey. Data were collected cross-sectionally in 2008 via questionnaires, including the Brief Symptom Inventory and Kiddo-KINDL Health-Related Quality of Life Questionnaire. Descriptive statistics were used to summarize data, whereas chi-square, ANOVA, Mann-Whitney U, Kruskal-Wallis, and t tests were used to compare groups. Median age of the participants was 16.0 years and 65.7% were male. Female gender, not going to school or work, dissatisfaction with school, contact with the family, chronic disease, chronic medication use, sleep problems, regular tobacco use, chronic disease in the family, and low quality of life score were associated with increased risk (GSI-Global Symptom Index>1 SD) for mental disorders. Physically active adolescents' use of tobacco, alcohol, other substances, and medications, as well as GSI and depression scores were lower and their quality of life scores were higher than those of their less active counterparts. Prevalence of psychological symptoms in adolescents living in orphanages were higher than in the general adolescent population. Physically active adolescents' mental health indices and abstinence behaviors with regard to tobacco, alcohol, and substances were more favorable. Encouraging adolescents to participate in sports and improving sports facilities in orphanages are interventions that can promote mental health.

    Adolescents are at a significant risk for binge drinking and illicit drug use. One way to protect against these behaviors is through participation in extracurricular activities. However, there is a debate about whether highly conscientious adolescents are more likely to participate in activities, which raises the concern of a confound. To disentangle these relationships, we tested the latent trajectories of substance use and personality across 3 years, with participation in activities and sports as time-varying predictors. We surveyed 687 adolescents (55 % female, 85.4 % Caucasian) in Western Australia schools across 3 years. At Time 1, the students were in Year 10 1 (mean age 15 years). The results showed that participation in activities and conscientiousness are related, but each uniquely predicts slower growth in substance use. Across waves, participation in activities predicted less risky substance use a year later, over and above conscientiousness development. These results suggest that there may be unique benefits of participation in activities that protect against risky substance use.

    Activity-based anorexia (ABA) is an animal model of anorexia nervosa that mimics core features of the clinical psychiatric disorder, including severe food restriction, weight loss, and hyperactivity. The ABA model is currently being used to study starvation-induced changes in the brain. Here, we examined hippocampal cell proliferation in animals with ABA (or the appropriate control conditions). Adolescent female Sprague-Dawley rats were assigned to 4 groups: control (24h/day food access), food-restricted (1h/day food access), exercise (24h/day food and wheel access), and ABA (1h/day food access, 24h/day wheel access). After 3 days of ABA, 5-bromo-2'-deoxyuridine (BrdU; 200mg/kg, i.p.) was injected and the rats were perfused 2h later. Brains were removed and subsequently processed for BrdU and Ki67 immunohistochemistry. The acute induction of ABA reduced cell proliferation in the dentate gyrus. This effect was significant in the hilus region of the dentate gyrus, but not in the subgranular zone, where adult neurogenesis occurs. Marked decreases in cell proliferation were also observed in the surrounding dorsal hippocampus and in the corpus callosum. These results indicate a primary effect on gliogenesis rather than neurogenesis following 3 days of ABA. For each brain region studied (except SGZ), there was a strong positive correlation between the level of cell proliferation and body weight/food intake. Future studies should examine whether these changes are maintained following long-term weight restoration and whether alterations in neurogenesis occur following longer exposures to ABA.

    Anorexia nervosa (AN) typically presents in adolescence and is highly comorbid with anxiety and depression, which often persist after elimination of AN symptomology. The activity-based anorexia (ABA) paradigm allows for evaluation of behavioral and neuroendocrine consequences of AN-like behaviors, including voluntary anorexia, hyperactivity, and disruption of the hypothalamic-pituitary-gonadal (HPG) and the hypothalamic pituitary adrenal (HPA) axis. Because ABA in adolescent females results in increased anxiety-like behavior in adulthood and the estrogen signaling system has been shown to play a role in anxiety and food intake, we investigated the role of ovarian hormones in adolescent ABA-treated rats, and long-term effects of mid- and late adolescent ABA exposure on behavior and estrogen signaling. While previous research demonstrated that two bouts of ABA during adolescence resulted in decreased time in the open arm of the elevated plus maze (EPM) and increased activity of the HPA axis in response to a novel stressor, here we show that one bout of ABA in mid-or late-adolescence did not result in the same behavioral outcome. Two exposures to ABA during adolescence were necessary to produce long-term anxiety-like behavior on the EPM. Finally, removal of ovarian hormones by ovariectomy (OVX) prior to puberty did not attenuate long-term behavioral consequences of ABA in adolescence, and estrogen receptor β (ERβ) expression level in the amygdala of ABA rats was significantly lower than control subjects. Taken together, these studies identify enduring effects of ABA in adolescent females that may be mediated by ABA-induced changes to CNS ERβ signaling that increase anxiety-like behaviors.

    Reduced vertebral strength is a clear risk factor for vertebral fractures. Men and women with vertebral fractures often have reduced vertebral size and bone mineral density (BMD). Vertebral strength is controlled by both genetic and developmental factors. Malnutrition and low levels of physical activity are commonly considered to result in reduced bone size during growth. Several studies have also demonstrated the general relationship between BMD and physical activity in the appendicular skeleton. In this study, we wanted to clarify the role of physical activity on vertebral bodies. Vertebral dimensions appear to generally be less pliant than long bones when lifetime changes occur. We wanted to explore the association between physical activity during late adolescence and vertebral strength parameters such as cross-sectional size and BMD. The association between physical activity and vertebral strength was explored by measuring vertebral strength parameters and defining the level of physical activity during adolescence. The study population consisted of 6,928 males and females who, at 15 to 16 and 19 years of age, responded to a mailed questionnaire inquiring about their physical activity. A total of 558 individuals at the mean age of 21 years underwent magnetic resonance imaging (MRI) scans. We measured the dimensions of the fourth lumbar vertebra from the MRI scans of the Northern Finland Birth Cohort 1986 and performed T2* relaxation time mapping, reflective of BMD. Vertebral strength was based on these two parameters. We analyzed the association of physical activity on vertebral strength using the analysis of variance. We observed no association between the level of physical activity during late adolescence and vertebral strength at 21 years. Copyright © 2013 Elsevier Inc. All rights reserved.

    Longitudinal cohort study. To compare functional outcomes between male and female patients before and after surgery for adolescent idiopathic scoliosis (AIS). There is no clear consensus in the existing literature with respect to sex differences in functional outcomes in the surgical treatment of AIS. A prospective, consecutive, multicenter database of patients who underwent surgical correction for adolescent idiopathic scoliosis was analyzed retrospectively. All patients completed Scoliosis Research Society-30 (SRS-30) questionnaires before and 2 years after surgery. Patients with previous spine surgery were excluded. Data were collected for sex, age, Risser grade, previous bracing history, maximum preoperative Cobb angle, curve correction at 2 years, and SRS-30 domain scores. Paired sample t tests were used to compare preoperative and postoperative scores within each sex. Independent sample t tests were used to compare scores between sexes. A P value of <0.05 was considered statistically significant. Seven hundred forty-four patients (621 females and 123 males) were included. On average, males were 1 year older than females. There were no differences between sexes in Risser grade, bracing history, maximum curve magnitude, or correction after surgery. Both males and females had similar improvement in all SRS-30 domains after surgery. Self-image/appearance had the greatest relative improvement. Males had better self-image/appearance scores preoperatively, better pain scores at 2 years, and better mental health and total scores both preoperatively and at 2 years. Both males and females were similarly satisfied with surgery. Males treated with surgery for AIS report better preoperative self-image, less postoperative pain, and better mental health than females. These differences may be clinically significant. For both males and females, the most beneficial effect of surgery is improved self-image/appearance. Overall, the benefits of surgery for AIS are similar for

    Research involving adolescent and young African American (AA) females has demonstrated that they face uncontrollable obstacles which can interfere with the negotiation of safer sexual behaviors. If these obstacles are perceived as uncontrollable, then these females may be at risk for the development of Learned Helplessness (LH). As the LH model predicts, if these obstacles are believed not to be in their control, it may lead to deficits in motivational or cognitive decision-making, deficits that could certainly influence their sexual risk taking behaviors. Therefore, the primary objective for this pilot study was to trial the Learned Helplessness Scale (LHS) to examine the perceptions of LH in this population. A convenience sample of 50 adolescent and young AA females between the ages of 16 and 21 were recruited from two clinics in Southeast Michigan. Scores on the LHS ranged from 20 to 57, with a mean score of 39.1 (standard deviation = 10.49). The higher range of scores in the sample demonstrates a continuum of LH among the participants in the study.

    To examine a computer-assisted, counselor-guided motivational intervention (CAMI) aimed at reducing the risk of unprotected sexual intercourse. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We conducted a 9-month, longitudinal randomized controlled trial with a multisite recruitment strategy including clinic, university, and social referrals, and compared the CAMI with didactic educational counseling in 572 female adolescents with a mean age of 17 years (SD = 2.2 years; range = 13-21 years; 59% African American) who were at risk for pregnancy and sexually transmitted diseases. The primary outcome was the acceptability of the CAMI according to self-reported rating scales. The secondary outcome was the reduction of pregnancy and sexually transmitted disease risk using a 9-month, self-report timeline follow-back calendar of unprotected sex. The CAMI was rated easy to use. Compared with the didactic educational counseling, there was a significant effect of the intervention which suggested that the CAMI helped reduce unprotected sex among participants who completed the study. However, because of the high attrition rate, the intent to treat analysis did not demonstrate a significant effect of the CAMI on reducing the rate of unprotected sex. Among those who completed the intervention, the CAMI reduced unprotected sex among an at-risk, predominantly minority sample of female adolescents. Modification of the CAMI to address methodological issues that contributed to a high drop-out rate are needed to make the intervention more acceptable and feasible for use among sexually active predominantly minority, at-risk, female adolescents.

  8. Melanoma risk: adolescent females' perspectives on skin protection pre/post-viewing a ultraviolet photoaged photograph of their own facial sun damage.

    Suntanning increases skin cancer risk and prematurely ages skin. Photoageing photography is an effective means of increasing adult ultraviolet radiation (UVR) awareness and skin-protection practices. While adults' largely positive suntanning-deterrence responses to photoageing photography are well-documented, comparatively little is known about the deterrence effectiveness of photoageing photography with adolescents. To help fill this knowledge gap, in-depth interviews were collected from 10 adolescent females and were subsequently subjected to interpretive phenomenological analysis. The emergent central theme - Having a tan and looking good in the short-term is okay, however, in the longer-term you can end up looking far worse… but still a tan is worth it - and its component subthemes reveal that the adolescent female's desire for a suntan is largely appearance driven. While photoaged photography is effective in increasing their awareness of the skin damage that UVR exposure causes, it does not alter their suntanning intentions. The analysis also revealed that one of the major barriers to adolescent females' adoption of skin-protective behaviours is their belief in their own invincibility. Hence, skin-protection interventions that lessen the aura of invincibility around adolescent females' understanding of their risk for developing skin cancers are vital to reducing the incidence of malignant melanoma.

  9. Influences of Tobacco Advertising Exposure and Conduct Problems on Smoking Behaviors Among Adolescent Males and Females

    PubMed Central

    2014-01-01

    Introduction: Adolescents with conduct problems are more likely to smoke, and tobacco advertising exposure may exacerbate this risk. Males’ excess risk for conduct problems and females’ susceptibility to advertising suggest gender-specific pathways to smoking. We investigated the associations between gender, conduct problems, and lifetime smoking and adolescents’ exposure to tobacco advertising, and we examined prospective relationships with smoking behaviors. Methods: Adolescents completed baseline (2001–2004; n = 541) and 5-year follow-up (2007–2009; n =320) interviews for a family study of smoking risk. Baseline interviews assessed conduct problems and tobacco advertising exposure; smoking behavior was assessed at both timepoints. Generalized linear models analyzed gender differences in the relationship between conduct problems, advertising exposure, and smoking behavior at baseline and longitudinally. Results: At baseline, among males, conduct problems were associated with greater advertising exposure independent of demographics and lifetime smoking. Among females at baseline, conduct problems were associated with greater advertising exposure only among never-smokers after adjusting for demographics. In longitudinal analyses, baseline advertising exposure predicted subsequent smoking initiation (i.e., smoking their first cigarette between baseline and follow-up) for females but not for males. Baseline conduct problems predicted current (i.e., daily or weekly) smoking at follow-up for all adolescents in adjusted models. Conclusions: The findings of this study reinforce that conduct problems are a strong predictor of subsequent current smoking for all adolescents and reveal important differences between adolescent males and females in the relationship between conduct problems, tobacco advertising behavior, and smoking behavior. The findings suggest gender-specific preventive interventions targeting advertising exposure may be warranted. PMID:24590388

    Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created 'obsessive-compulsive and related disorders' chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models. Self-report questionnaires assessing disorder symptoms were completed by 3149 Australian adolescents. The fit of correlated factor models was calculated separately in males and females, and measurement invariance testing compared parameters of the best-fitting model between males and females. All theoretical models of the classification of BDD had poor fit to the data. Good fit was found for a novel model where BDD symptoms formed a distinct latent factor, correlated with affective disorder and eating disorder latent factors. Metric non-invariance was found between males and females, and the majority of factor loadings differed between males and females. Correlations between some latent factors also differed by sex. Only cross-sectional data were collected, and the study did not assess a broad range of DSM-5 defined eating disorder symptoms or other disorders in the DSM-5 obsessive-compulsive and related disorders chapter. This study is the first to statistically evaluate competing models of BDD classification. The findings highlight the unique features of BDD and its associations with affective and eating disorders. Future studies examining the classification of BDD should consider developmental and sex differences in their models. Copyright © 2017. Published by Elsevier B.V.

    The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods). Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised. First year female students from three different Schools and Faculties at the University of Limpopo, Turfloop Campus, South Africa, participated in the study. Using the availability and convenient sampling method, 75 students were selected for this study. For the quantitative aspect of the study, the Rosenberg Self-esteem Measure was used to measure self-esteem. For the qualitative part, a topic guide was used for the focus group discussions. Analysis of Variance (ANOVA) and the Pearson's Product Moment Correlation were used to analyse the quantitative data, while the phenomenological principle of open coding used for the thematic analysis. Results showed that there is a relationship between body mass and self-concept and that overweight participants tend to have a low self-esteem. Low self-esteem was perceived to be aggravated by a number of factors, like the attitude of the media and the society. Participants who are overweight also indicated that they are limited in certain activities of daily living (e.g., sports) as a result of their body mass. They expressed mixed feelings and frustration when it comes to such activities. The above results did not differ from those reported from western cultures. Support groups, life-skills programmes and psychotherapy should be

    This study was an investigation of female adolescents' perceptions, attitudes, and beliefs towards science and reading science-related texts. Three surveys were used to collect data from 253 middle school students in Grade 7 and Grade 8 and six interviews were conducted with students. The interviews allowed a deeper analysis of the value students placed on science and on reading science-related texts. The quantitative data were collected through the following surveys: Test of Science Related Attitudes, Motivation for Reading Informational Books in School adapted, and Metacognitive Awareness Reading Strategies Inventory adapted. The purpose of the surveys was to provide a comprehensive picture of students' self-reported perceptions, attitudes, and beliefs towards science and the motivation to engage. Literacy processes and practices make engagement and learning in science possible; however, intrinsic motivation and cognitive strategies are critical influential components that educators cannot overlook. The female adolescents in this study expressed greater competence when involved in learning science through inquiry experimentation integrated with literacy presented in different formats.

    Adolescent females have a higher prevalence of depression in comparison to their male peers - a disparity that has been increasing over the past decade. Depression is of concern as it is associated with chronic disease and to immune dysregulation, which may be one mechanism linking depression to future pathology. This study examined the extent to which sex moderated the association between depressive symptoms and immune dysregulation during adolescence using Epstein-Barr virus (EBV) reactivation, a biomarker of cellular immune response, as a model. A representative community sample of 259 female and 279 male adolescents aged 11-17 years who were EBV IgG positive were examined. Trained interviewers collected the data during two home visits, one week apart. Depressive symptoms were measured at the first visit using the 9 item short-form of the Center for Epidemiologic Studies-Depression scale. EBV biomarkers were collected via saliva at the second visit and included a qualitative measure of EBV viral capsid antigen immunoglobulin G to assess prior EBV infection and a quantitative measure of EBV DNA to assess the number of viral copies shed in the saliva. In multivariable logistic regression analyses, increasing depressive symptoms were significantly associated with salivary shedding of EBV DNA for adolescent females only (logit=0.66, se=0.30, p<0.05), and the interaction between sex and depressive symptoms on salivary shedding of EBV DNA was statistically significant (logit=-1.19, se=0.42, p<0.01). Sensitivity analyses were conducted in which sex was examined as a moderator in the relationship between depressive symptoms and salivary EBV DNA quantitative copies via Tobit regression; results were consistent with the presented findings. Depressive symptoms are associated with EBV reactivation among EBV positive female adolescents, but not males. Future research is needed to examine EBV reactivation in female adolescents as a mechanism linking depression to future

    Background The potential synergistic effects of multiple dietary and physical activity behaviours on the risk of chronic conditions and health outcomes is a key issue for public health. This study examined the prevalence and clustering patterns of multiple health behaviours among a sample of adolescents in the UK. Methods Cross-sectional survey of 176 adolescents aged 12–16 years (49% boys). Adolescents wore accelerometers for seven days and completed a questionnaire assessing fruit, vegetable, and breakfast consumption. The prevalence of adolescents meeting the physical activity (≥ 60 minutes moderate-to-vigorous physical activity/day), fruit and vegetable (≥ 5 portions of FV per day) and breakfast recommendations (eating breakfast on ≥ 5 days per week), and clustering patterns of these health behaviours are described. Results Boys were more active than girls (p < 0.001) and younger adolescents were more active than older adolescents (p < 0.01). Boys ate breakfast on more days per week than girls (p < 0.01) and older adolescents ate more fruit and vegetables than younger adolescents (p < 0.01). Almost 54% of adolescents had multiple risk behaviours and only 6% achieved all three of the recommendations. Girls had significantly more risk factors than boys (p < 0.01). For adolescents with two risk behaviours, the most prevalent cluster was formed by not meeting the physical activity and fruit and vegetable recommendations. Conclusion Many adolescents fail to meet multiple diet and physical activity recommendations, highlighting that physical activity and dietary behaviours do not occur in isolation. Future research should investigate how best to achieve multiple health behaviour change in adolescent boys and girls. PMID:19624822

    Physical activity (PA) reduces symptoms of Attention Deficit Hyperactivity Disorder (ADHD); interventions to increase PA may improve functioning and health for adolescents with ADHD. Mobile health (mHealth) technology and social media constitute promising interactive modalities for engaging adolescents-who are at highest risk for ADHD treatment drop-out-in interventions to increase PA. The current pilot study evaluated feasibility and acceptability of an innovative intervention incorporating an mHealth-linked wearable activity tracker (Fitbit Flex) and a Facebook group to increase PA among adolescents with ADHD. 11 adolescents diagnosed with ADHD (age 14-18, m = 15.5; 54% female) participated in a 4-week trial utilizing the Fitbit Flex in conjunction with (1) weekly personalized step count goals (2) social support through a Facebook group and (3) daily text messages about PA. The study took place in the greater Seattle, Washington area in the fall of 2015. Adolescents completed online surveys twice per week to rate their ADHD symptoms and positive and negative mood states, and parents rated adolescent ADHD symptoms weekly. Participants were adherent to the study protocol and acceptability of the intervention was high. Linear mixed models indicated that participants significantly increased their average weekly steps over the course of the study and demonstrated improvements in both adolescent and parent-reported ADHD Inattentive symptoms. Results indicate that this mHealth intervention is engaging and promising for increasing PA among adolescents with ADHD, and warrant further study. Implications for improving ADHD symptoms and overall functioning for this undertreated population are discussed.

    This study fills a gap regarding the perspectives of Mexican American female adolescents on dating relationships and dating violence (DV). This was a qualitative descriptive study. Focus groups included 20 Mexican American young women, primarily first and second generation, mean age 14.5 years (SD= 2.5). Data were analyzed with categorical analysis. Participants described key components of DV and identified cultural aspects that may serve to promote healthy dating relationships. Family-based interventions to promote exploration of gender roles and parent-child communication may foster biculturalism as well as promote healthy dating relationships and prevent violence within this cultural group. In the United States, 10% to 40% of teens experience DV. Hispanic females experience more physical DV than their White peers. © 2012 Sigma Theta Tau International.

    Introduction. Deprivation of parents might decrease self-esteem (SE) and result in affective and social incompatibility. In this randomized control trial, we examined the effect of aerobics exercise on SE among female adolescents living with no natural family. Materials and Methods. The sample consisted of all female adolescents aged 13 to 19 years (n: 72) who were covered by Isfahan Welfare organization. Participants were assigned into intervention and control groups by matched random sampling. Intervention included 8 weeks of aerobics exercise. Coppersmith SE inventory was administered before and after intervention as well as after one month follow-up. Results. No significant difference was seen between pre-SE scores of intervention (32.7 ± 8.4) and control (33.0 ± 6.7) groups (t = .16, P = .87). A significant difference was obtained in post-SE scores (40.2 ± 5.7 versus 34.7 ± 6.8, t = 3.58, P = .001) and in one month follow-up scores (36.4 ± 5.2 versus 33.0 ± 5.2, t = 2.25, P = .03). Discussion. The results demonstrated a low level of pre-SE in both groups. However, a significant improvement was seen in posttest of intervention group which persisted even one month after intervention. It supports the use of aerobics for female adolescents deprived from family life. PMID:25610905

    The present study examined the relationship between body image and adolescent girls' activity on the social networking site (SNS) Facebook (FB). Research has shown that elevated Internet "appearance exposure" is positively correlated with increased body image disturbance among adolescent girls, and there is a particularly strong association with FB use. The present study sought to replicate and extend upon these findings by identifying the specific FB features that correlate with body image disturbance in adolescent girls. A total of 103 middle and high school females completed questionnaire measures of total FB use, specific FB feature use, weight dissatisfaction, drive for thinness, thin ideal internalization, appearance comparison, and self-objectification. An appearance exposure score was calculated based on subjects' use of FB photo applications relative to total FB use. Elevated appearance exposure, but not overall FB usage, was significantly correlated with weight dissatisfaction, drive for thinness, thin ideal internalization, and self-objectification. Implications for eating disorder prevention programs and best practices in researching SNSs are discussed.

    Background: Adolescents consume more sugar-sweetened beverages than do individuals in any other age group, but it is unknown how the type of sugar-sweetened beverage affects metabolic health in this population. Objective: The objective was to compare the metabolic health effects of short-term (2-wk) consumption of high-fructose (HF) and high-glucose (HG)–sweetened beverages in adolescents (15–20 y of age). Design: In a counterbalanced, single-blind fashion, 40 male and female adolescents completed two 2-wk trials that included 1) an HF trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g fructose/d and 15 g glucose/d) for 2 wk and 2) an HG trial in which they consumed 710 mL of a sugar-sweetened beverage/d (equivalent to 50 g glucose/d and 15 g fructose/d) for 2 wk in addition to their normal ad libitum diet. In addition, the participants maintained similar physical activity levels during each trial. The day after each trial, insulin sensitivity and resistance [assessed via Quantitative Insulin Sensitivity Check Index (QUICKI) and homeostatic model assessment of insulin resistance (HOMA-IR) index] and fasting and postprandial glucose, lactate, lipid, cholesterol, insulin, C-peptide, insulin secretion, and clearance responses to HF or HG mixed meals were assessed. Results: Body weight, QUICKI (whole-body insulin sensitivity), HOMA-IR (hepatic insulin resistance), and fasting lipids, cholesterol, glucose, lactate, and insulin secretion or clearance were not different between trials. Fasting HDL- and HDL3-cholesterol concentrations were ∼10–31% greater (P < 0.05) in female adolescents than in male adolescents. Postprandial triacylglycerol, HDL-cholesterol, HDL3-cholesterol, and glucose concentrations were not different between HF and HG trials. The lactate incremental area under the curve was ∼3.7-fold greater during the HF trial (P < 0.05), whereas insulin secretion was 19% greater during the HG trial (P < 0

    Patients with anorexia nervosa (AN) exhibit high rates of psychiatric comorbidity. To disentangle the effects of duration of illness on comorbid psychiatric symptoms, we investigated the rates of comorbid psychiatric disorders, suicidality and self-harm behaviour in adolescent patients with a first onset of AN. In adolescent females (n = 148) with a first onset of AN, body mass index, psychiatric comorbidity (according to DSM-IV), depressive symptoms, suicidality and self-injurious behaviour were assessed. Seventy patients (47.3%) met the criteria for at least one comorbid psychiatric disorder. The binge-purging subtype was associated with increased rates of psychiatric comorbidity, suicidality and self-injurious behaviour. The severity of eating disorder-specific psychopathology influenced current psychiatric comorbidity and suicidal ideation. Prevalence rates of comorbid psychiatric disorders and suicidal ideation are considerably lower among adolescents with AN compared with adults. An early and careful assessment, along with adequate treatment of the eating disorder, might prevent the development of severe psychiatric comorbidities.

    Placement into foster care is driven by a number of factors, many of which are associated with adolescent childbirth. Yet, there are few studies that identify the experiences and characteristics that predict adolescent childbirth among girls who spend time in foster care. A longitudinal, population-based data set was constructed by probabilistically matching California child protective service records for female foster youth to maternal information available on vital birth records for children born between 2001 and 2010. Rates of childbirth among girls in foster care after their 10th birthday were generated. Chi-square tests assessed differences and survival models were specified to determine the rate of childbearing across key characteristics. Among the 30,339 girls who spent time in foster care as adolescents, 18.3% (5,567) gave birth for the first time before their 20th birthday. At a bivariate level, significant differences (p < .001) in birth rates were observed across demographic characteristics, maltreatment history, and foster care placement experiences. In the fully adjusted survival model, the highest birth rates were observed among girls who entered care between ages 13 and 16 years; had been in care for relatively short periods of time; lived in congregate care at the estimated date of conception; had a history of running away; and were Latina, black, or Native American. The results suggest that there are identifiable risk factors associated with early childbirth among girls in foster care, which can help determine the timing and location of reproductive health services to minimize unintended pregnancy and maximize adolescent health and well-being.

    China, as other Southeast Asian countries, has witnessed an increased use in amphetamine-type stimulants (ATS) amongst urban youth. Amongst female adolescents who both sell sex and use ATS, risk behaviours are compounded resulting in even poorer health outcomes. However, limited knowledge exists on ATS use patterns and ATS-related risk behaviours, particularly in this context. This research aimed to improve the understanding of these issues amongst female adolescents who use ATS and sell sex, and to inform future programming. This study utilised monthly focus group discussions (four in total) with the same study participants in Yunnan, China. From within a drug-treatment programme, female adolescents who reported both a history of drug use and selling sex were purposively enrolled in the study. Participating adolescent females were aged 17-19 years and were all internal-migrants with low literacy. All reported polydrug use (mainly methamphetamine and heroin, whereas ecstasy and ketamine have been infrequently employed). Being less informed about risks of drug use and lack of sexual and reproductive health knowledge seemed to contribute to problematic drug use, rough and prolonged sexual intercourse, inconsistent condom use and ineffective contraceptive practice. For their income, participants largely relied on selling sex, which was frequently coupled with drug sharing services to clients. However, despite the practices, women did not self-identify as sex workers, and therefore did not think that existing intervention services targeting female sex workers were relevant to them. Moreover, criminalization and stigmatisation of drug use and selling sex impeded their access to care services. Current harm reduction and HIV/sexually transmitted infection (STI) prevention services are unlikely to address the demand of female adolescents engaged in drug use and commercial sex. Our findings highlight that a comprehensive and coordinated harm reduction and sexual and

    There is increasing evidence that heavy ethanol exposure in early life may produce long-lasting neurobehavioral consequences, since brain structural maturation continues until adolescence. It is well established that females are more susceptible to alcohol-induced neurotoxicity and that ethanol consumption is increasing among women, especially during adolescence. In the present study, we investigated whether chronic ethanol exposure during adolescence through early adulthood in female rats may induce hippocampal histological damage and neurobehavioral impairments. Female rats were treated with distilled water or ethanol (6.5 g/kg/day, 22.5% w/v) by gavage from the 35(th)-90(th) day of life. Ethanol-exposed animals displayed reduced exploration of the central area and increased number of fecal boluses in the open field test indicative of anxiogenic responses. Moreover, chronic high ethanol exposure during adolescence induced marked impairments on short-term memory of female rats addressed on social recognition and step-down inhibitory avoidance tasks. These neurobehavioral deficits induced by ethanol exposure during adolescence through early adulthood were accompanied by the reduction of hippocampal formation volume as well as the loss of neurons, astrocytes and microglia cells in the hippocampus. These results indicate that chronic high ethanol exposure during adolescence through early adulthood in female rats induces long-lasting emotional and memory deficits associated with morphological and molecular alterations in the hippocampus. © The Author(s) 2015.

    Accidental injury and homicide, relatively common among adolescents, often follow risky behaviors; those are done more by boys and by adolescents with greater behavioral disinhibition (BD). Neural processing during adolescents' risky decision-making will differ in youths with greater BD severity, and in males vs. females, both before cautious behaviors and before risky behaviors. 81 adolescents (PATIENTS with substance and conduct problems, and comparison youths (Comparisons)), assessed in a 2 x 2 design ( Comparisons x Male:Female) repeatedly decided between doing a cautious behavior that earned 1 cent, or a risky one that either won 5 or lost 10 cents. Odds of winning after risky responses gradually decreased. Functional magnetic resonance imaging captured brain activity during 4-sec deliberation periods preceding responses. Most neural activation appeared in known decision-making structures. PATIENTS, who had more severe BD scores and clinical problems than Comparisons, also had extensive neural hypoactivity. Comparisons' greater activation before cautious responses included frontal pole, medial prefrontal cortex, striatum, and other regions; and before risky responses, insula, temporal, and parietal regions. Males made more risky and fewer cautious responses than females, but before cautious responses males activated numerous regions more than females. Before risky behaviors female-greater activation was more posterior, and male-greater more anterior. Neural processing differences during risky-cautious decision-making may underlie group differences in adolescents' substance-related and antisocial risk-taking. Patients reported harmful real-life decisions and showed extensive neural hypoactivity during risky-or-cautious decision-making. Males made more risky responses than females; apparently biased toward risky decisions, males (compared with females) utilized many more neural resources to make and maintain cautious decisions, indicating an important risk

    Sex trafficking has been a long-standing concern in Nepal. Very little has been achieved, however, in terms of actual reduction in the number of victims despite numerous anti-sex trafficking programs. This situation may be attributable to a lack of empirical evidence upon which to formulate anti-sexual trafficking interventions. This study aimed to assess sex trafficking-related knowledge, awareness and attitudes, and factors associated with sex trafficking awareness and attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns among adolescent female students in Nepal. A cross-sectional study was conducted between August-September 2013 among 292 adolescent female students (>10 years old) using systematic random sampling from three high schools in Sindhupalchowk district, Nepal. As an initial step, descriptive analyses were employed to characterize the data and multivariate logistic regression analyses were used to explore factors associated with sex trafficking awareness and related attitudes. Seventy-six percent of sampled students reported that they were aware of sex trafficking and 94.6% indicated media (i.e., radio or television) as the primary sources of their knowledge. Fifty-one percent mentioned relatives/friends as mediators of sex trafficking, 60.4% reported promise for better jobs as the primary attraction behind sex trafficking, and 48.6% mentioned adolescent females as the most vulnerable group for sex trafficking. Over half (56.8%) of the respondents had positive attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns. Age (OR = 3.38, 95% CI:2.51-4.55), parents' occupation (OR = 3.89, 95% CI:1.58-9.58), and having a radio/TV at home (OR = 6.67, 95% CI:3.99-9.54) were significantly associated with awareness, whereas being younger (OR = 0.67, 95% CI:0.55-0.79) and having joint-family (OR = 2.67, 95% CI:1.49-4.80) were significantly associated with having a positive attitudes towards the

    The purpose of this study was to determine whether parents' current and previous physical activity practice is associated with adolescents' physical activity. The sample was composed of 1231 adolescents (14-17 years), and 1202 mothers and 871 fathers were interviewed. Weight and height of the adolescents were measured. Self-reported parents' weight and height were obtained. The current and previous physical activity levels (Baecke's questionnaire) of parents (during childhood and adolescence) and adolescents' physical activity levels were obtained using a questionnaire. The magnitude of the associations between parent and adolescent physical activity levels was determined by binary logistic regression (adjusted by sex, age, and socioeconomic level of adolescents and education level of parents). The current physical activity practice by parents was associated with adolescents' physical activity (p<0.001). The physical activities reported by parents in their childhood and adolescence were also associated with higher physical activity levels among adolescents. Adolescents whose parents were both physically active in the past and present were six times (OR=6.67 [CI=1.94-22.79]) more likely to be physically active compared to adolescents with no parents who were physically active in the past. The current and previous physical activities of parents were associated with higher levels of physical activity in adolescents, even after controlling for confounding factors.

    This study examined gender stereotypes in peer ratings of femininity and masculinity for adolescent participants in three sports. Following a preliminary study of gender stereotyping of several sports, high school students rated unfamiliar cohorts each of whom was described in a single paragraph as either a male or female dedicated participant in one of three sports. A total of 12 different descriptive paragraphs were used in a 2 (race) x 2 (sex) x 3 (sport) design. Each of these paragraphs, although short, ascribed a variety of traits that could be seen by raters as the independent variables: name (initials only), age, race, gender, hours of practice per week, number of competitions/performances per year, sport, and self-confidence. For this reason, raters were highly unlikely to surmise that sex and sport were the primary independent variables in the study. As predicted, there was a consistent decrease in rated femininity and increase in masculinity for both male and female adolescent targets as they switched from participating in a "feminine" (ballet) to a neutral (tennis) to a "masculine" (karate) sport. These results suggest that sex stereotypes for certain sports may influence who elects to participate and how participants are viewed by others.

    Past research has consistently shown that romantic experiences during adolescence affect the nature and quality of romantic relationships during emerging adulthood. However, less is known about the role of adolescent sexual experiences in future sexual and romantic relationships. The current study examined the impact of different forms of sexual activity at age 16 (within a romantic relationship or casual encounters) on the nature and quality of sexual experiences in romantic relationships at age 23. One hundred and forty four (59.7% females) 16 year olds reported on their sexual activity within a romantic relationship or sexual encounters. In addition they reported on the quality of relationships they were involved in and their tendency to suppress emotions (included as an aspect of personality). At age 23 they reported on their romantic and sexual experiences during the past 2 years (number of short lived relationships, numbers of friends with benefits, casual sex encounters) and the quality of their romantic relationships (the duration of their longest relationship, partner support and feelings of certainty in the relationships). Findings showed that the tendency to suppress emotions was associated with lower likelihood to engage in casual sex at age 23. However, greater sexual experience in casual encounters during adolescence was consistently longitudinally associated with different forms of casual sexual encounters and short romantic involvements above and beyond the contribution of personality. In contrast, sexual activity within a romantic relationship predicted only a few indices of the quality of romantic involvement at age 23. The distinctive role of casual sexual activity and sexual activity within a romantic relationship for future sexual and romantic activities is discussed.

    Alcohol use has been linked to risky sexual practices among adolescents. However, limited research on alcohol use and risky sexual behavior has been conducted on African-American female adolescents. This study examined high quantity of alcohol as a longitudinal predictor of risky sexual behavior and sexually transmitted diseases (STDs) among African-American female adolescents, a high-risk population for STDs. Three hundred ninety-three adolescent females, 15 to 21 years, were assessed on sociodemographics, alcohol use, and risky sexual behaviors. Participants also provided 2 swab specimens that were assayed for STDs. High quantity of alcohol use was defined as ≥ 3 drinks in 1 sitting. Binary generalized estimating equation models were conducted assessing the impact of alcohol use at baseline on risky sexual behavior and STDs over a 12-month period. Age, intervention group, and baseline outcome measures were entered as covariates. The results indicated that high quantity of alcohol use predicted positive TV test results, inconsistent condom use, high sexual sensation seeking, multiple sexual partners, sex while high on alcohol or drugs, and having anal sex over a 12-month follow-up period. These findings suggest that HIV/STD-related behavioral interventions for African-American adolescents should discuss the link between alcohol and HIV/STD-risk behavior. A deeper understanding is paramount to the development of efficacious prevention programs at individual and community levels.

    Primary dysmenorrhoea, the most common gynaecologic problem of adolescent females, is commonly treated with nonsteroidal anti-inflammatory drugs or oral contraceptive pills. To compare the effect of zinc sulphate with that of placebo on the control of pain severity and duration in adolescent girls with primary dysmenorrhoea. In a three-month randomised double-blind placebo-controlled clinical trial, 120 adolescent females with primary dysmenorrhoea were randomly divided into two groups of sixty: an intervention group (zinc) and a control group (placebo). Zinc was administered in the form of a capsule containing 50 mg/day zinc sulphate beginning on the first day of menses and continuing until three days prior to the end of menses. Each month, the duration and severity of primary dysmenorrhoea were determined. Severity scoring was performed by using a 0-10 scaling system. In the first month, the duration of pain was significantly lower in the zinc group compared with the placebo group (P-value = 0.044), while there was no significant difference in pain severity between the groups (P-value = 0.497). In the second and third month, pain severity and duration in the zinc group were significantly lower than the placebo group (P-value <0.001). Both pain duration and pain severity were decreased by taking oral zinc. The results of our interventional study suggests that zinc may be used to treat primary dysmenorrhoea in adolescents. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    OBJECTIVE To assess the prevalence and correlates of insufficient physical activity in adolescents in Peru. METHODS We used a self-administered questionnaire developed from Global school-based Student Health Survey to collect information from secondary school students in North Lima and Callao in 2015. We carried out Poisson regression with robust variance using generalized linear models to estimate the crude and adjusted prevalence ratios (APR) with 95% confidence intervals (95%CI) of insufficient physical activity for its correlates. RESULTS We have found that 78% of the adolescents did not meet the global recommendation of the World Health Organization on physical activity in the last week before the survey. Female respondents (APR = 1.13, 95%CI 1.04-1.21), respondents who perceived themselves as overweight (APR = 1.10, 95%CI 1.03-1.18), and respondents who consumed insufficient vegetables and fruits [no vegetables (APR = 1.30, 95%CI 1.06-1.59), no fruits (APR = 1.15, 95%CI 1.00-1.31) as compared to those who consumed ≥ 2 servings every day in the last seven days] were more likely to report insufficient physical activity. Adolescents who worked after school (APR = 0.92, 95%CI 0.84-0.99), had physical education classes five times per week (APR = 0.94, 95%CI 0.88-0.99), and had parental supervision (APR = 0.92, 95%CI 0.87-0.98) were less likely to report insufficient physical activity. CONCLUSIONS Sex, work after school, perceived body weight, physical education class, parental support, and healthy dietary behaviors were associated with insufficient physical activity. Attempts to improve physical activity should look for ways to enhance leisure-time physical activity, parental support, physical education classes, healthy dietary behaviors, and normal body weight maintenance in adolescents with integrated efforts from the family and school.

Female adolescents (N = 22) who were sexually experienced, predominately Hispanic (73%, n = 16) with a mean age of 17.7 years (range, 15-20 years). None. Interviews were used to assess perspectives on vaginal health, specific vaginal hygiene practices, and attitudes about vaginally-placed products (contraceptive rings, intrauterine devices), and proposed multipurpose technologies administered as ring or gel). The interviews were transcribed and coded for relevant themes. Overlapping themes included young women's view of their vagina as a space that needed to be healthy for sexual partners and future fertility. The vagina could not be presumed to be healthy and conversations about vaginal health were limited to include only specific individuals. All reported a variety of practices to maintain their vaginal health, including showering 1-5 times a day and using soaps specifically for the vagina. Attitudes about vaginally-placed products revealed concerns about the sensory experience of having a product in the vagina, safety concerns and interest in the product's objective (prevention of pregnancy or infection). Adolescents have very specific views and practices about their vaginas. Clinicians should initiate conversations about vaginal health and hygiene with adolescents and focus on the normalcy of the vagina. Development of vaginally-placed products should focus on the sensory experience, safety, and purpose of the product. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    The current study sought to explore subtypes of adolescents within a sample of female juvenile offenders. Using the Millon Adolescent Clinical Inventory with 101 female juvenile offenders, a two-step cluster analysis was performed beginning with a Ward's method hierarchical cluster analysis followed by a K-Means iterative partitioning cluster analysis. The results suggest an optimal three-cluster solution, with cluster profiles leading to the following group labels: Externalizing Problems, Depressed/Interpersonally Ambivalent, and Anxious Prosocial. Analysis along the factors of age, race, offense typology and offense chronicity were conducted to further understand the nature of found clusters. Only the effect for race was significant with the Anxious Prosocial and Depressed Intepersonally Ambivalent clusters appearing disproportionately comprised of African American girls. To establish external validity, clusters were compared across scales of the Behavioral Assessment System for Children - Self Report of Personality, and corroborative distinctions between clusters were found here.

    Unlike other types of cancer, skin cancer incidence rates are on the rise and adolescent females are particularly likely to tan indoors, a major risk factor. However, little research has examined the role of media use in encouraging or discouraging this dangerous behavior in this population. To empirically assess the links between media use, indoor tanning-related outcome expectations, and behavioral intentions. A survey of adolescent females ( N = 510) ages 15 to 18 in the Southeastern United States assessed demographics, types of media use, and indoor tanning intentions. Significant correlations between media use and indoor tanning outcome expectations were found. Use of interpersonal and social media (i.e., talking on the phone, texting, and online social media) were positively associated with positive outcome expectations about indoor tanning and negatively associated with negative outcome expectations. A path analysis revealed that interpersonal/social media use had indirect associations with indoor tanning intentions via tanning outcome expectations. Mass media use (e.g., news media, entertainment media, and magazines) was not significantly associated with most indoor tanning outcome expectations but did have a direct negative association with behavioral intentions. There are important relationships between media use, indoor tanning outcome expectations, and behavioral intentions. Interpersonal and social media use may help cultivate outcome expectations that encourage indoor tanning, which in turn may increase intentions to tan, while news media consumption in particular may reduce intentions to tan. These findings highlight the social nature of adolescent females and point to specific intervention channels for reducing indoor tanning among this population.

    Female adolescents in reproductive age are a susceptible group to anemia and micronutrient deficiencies. The objective of this study was to know the nutritional, anthropometric and dietetic status, the prevalence of anemia, depletion of iron deposits (FeD) and Vitamin A deficiency (VAD) in female adolescents. Seventy-eight not pregnant female adolescents (15.9 +/- 1.1 years old), from an urban and a periurban zone of Maracaibo, and a rural zone near this city, without infectious and inflammatory processes, were analyzed. Anemia in adolescents was considered when Hb < 120 g/L; FeD: ferritin < 12 microg/L; VAD serum retinol <20 microg/dL; risk of VAD (RVAD) 20-30 microg/dL. The data were analyzed with the SAS program and expressed as Means +/- Standard Deviations, statistical significance was considered when p < 0.05. The percentage of caloric and protean adjustment in all groups was below the daily requirements. Adolescents from the rural zone showed significant lower values of weight (p = 0.0024), height (p = 0.0027), body mass index BMI (p = 0.0487), fatty area (p = 0.0183), MCV (p = 0.0241), MCH (p = 0.0488), MHCC (p = 0.0228), and the highest prevalence of anemia (66.67%), anemia+FeD (33.33%), and anemia+FeD+RVAD (5.56%), with respect to adolescents from the urban zone. Although, anemic adolescents from the rural zone showed a non significant decrease of the iron percentage adjustment. Iron requirements are increased during adolescence, reaching a maximum at the peak of growth and remaining almost as high in girls after menarche, to replace menstrual losses. The low iron status among adolescents from the rural zone determine that this is a high risk group to anemia and FeD and they require prevention, control and suplementation strategies.

    Major depressive disorder (MDD) is a leading cause of disability worldwide and occurs commonly first during adolescence. The insular cortex (IC) plays an important role in integrating emotion processing with interoception and has been implicated recently in the pathophysiology of adult and adolescent MDD. However, no studies have yet specifically examined the IC in adolescent MDD during processing of faces in the sad-happy continuum. Thus, the aim of the present study is to investigate the IC during sad and happy face processing in adolescents with MDD compared to healthy controls (HCL). Thirty-one adolescents (22 female) with MDD and 36 (23 female) HCL underwent a well-validated emotional processing fMRI paradigm that included sad and happy face stimuli. The MDD group showed significantly less differential activation of the anterior/middle insular cortex (AMIC) in response to sad versus happy faces compared to the HCL group. AMIC also showed greater functional connectivity with right fusiform gyrus, left middle frontal gyrus, and right amygdala/parahippocampal gyrus in the MDD compared to HCL group. Moreover, differential activation to sad and happy faces in AMIC correlated negatively with depression severity within the MDD group. Small age-range and cross-sectional nature precluded assessment of development of the AMIC in adolescent depression. Given the role of the IC in integrating bodily stimuli with conscious cognitive and emotional processes, our findings of aberrant AMIC function in adolescent MDD provide a neuroscientific rationale for targeting the AMIC in the development of new treatment modalities.

  2. Active gaming in Dutch adolescents: a descriptive study

    PubMed Central

    2012-01-01

    Background Adequate levels of physical activity are part of a healthy lifestyle and in this way linked to better health outcomes. For children and adolescents, the physical activity guideline recommends at least 60 minutes of moderate-to-vigorous physical activity every day. However, many adolescents are not physically active enough and they spend a lot of their time on sedentary activities (such as video games). A new generation of video games that require body movements to play them, so-called "active games", could serve to increase physical activity in adolescents. The activity level while playing these games is comparable to light-to-moderate intensity physical activity. The current study aims to increase our understanding of 1) the demographic characteristics of adolescents who play active games regularly (≥ 1 hour per week) and non-regularly (<; 1 hour per week), 2) time spent on active games, 3) the contribution of active games to daily physical activity and 4) the type and amount of activities being replaced by active gaming. Methods A cross-sectional survey was conducted in a Dutch internet panel, questioning adolescents in conjunction with one of their parents. A random sample of 320 households (with stratification on gender of the parent and the adolescent, the age of the adolescent and the region of the household) was selected that owned a console or application for active video games and that had a child aged 12 through 16 years. 201 child–parent couples (63% response) completed an internet survey with questions about demographics, physical activity and sedentary behaviour, and gaming behaviour. The questionnaire also contained questions designed to assess whether and how active gaming replaces other activities. Besides descriptive analyses, independent t-test, Pearson’s chi-square and Mann–Whitney test (when data were not normally distributed) were used for comparisons between regular and non-regular active gamers.

    Self-compassion has been associated with well-being in adult samples, but has rarely been assessed in adolescents. In this study, 90 students ages 11–18 completed an online survey assessing self-compassion, life satisfaction, perceived stress and positive and negative affect. Findings indicated that older female adolescents had lower self-compassion than either older male adolescents or early adolescents of either gender, and self-compassion was associated significantly with all dimensions of emotional well-being with the exception of positive affect. Additionally, phase of adolescence, but not gender, was found to moderate the relationship between self-compassion and dimensions of well-being; for older adolescents, the inverse relationship between self-compassion and negative affect was stronger. Lastly, the influence of the various components of self-compassion was investigated and discussed. PMID:25750655

    The introduction of vaccination against Human Papillomavirus (HPV) in adolescent girls in 2006 has focused virological surveillance on this age group. As few studies have evaluated HPV infections in young populations, further data are needed in order to improve and extend prophylactic policy and to monitor epidemiological changes. The present study aimed at evaluating overall and type-specific HPV prevalence in both female and male adolescents in Italy. HPV DNA detection and genotyping was performed on urine samples collected from 870 unvaccinated adolescents (369 females, 501 males, 11-18 years of age) in five cities in Italy. Following DNA extraction by means of a commercial kit (NucliSENS®-miniMAG®, bioMérieux), the L1 gene fragment was PCR amplified and genotyped by restriction fragment length polymorphism analysis. HPV DNA was detected in 1.5% of all samples, and in 3% and 0.4% of samples from females and males, respectively. In approximately 70% of HPV DNA positive adolescents, the infection was due to a single genotype, with 88.9% of genotypes belonging to the HR-clade. The only two HPV-positive boys (14 and 18 years old) had HPV-70 genotype. Only one of the 11 HPV-infected girls was in the 11-14 age-group. HPV prevalence was 4.2% in girls aged 15-18 years and 60% of infections were due to vaccine types HPV-16 or HPV-6/-11. This is one of the few studies, the first conducted in Italy, on HPV infection in adolescents. Urine testing is the easier way of detecting HPV infection in younger populations. Our data revealed a very low HPV prevalence, and no infections were observed in the 12-year-old vaccine target population. The majority of infections were seen in females aged 15-18 years. Overall, more than 50% and 30% of the potentially persistent HPV infections detected in this group could have been prevented by the quadrivalent and the bivalent vaccines, respectively.

    Levels of perceived parental care and control among 24 female Israeli adolescents presenting at emergency rooms after a self-poisoning act of low lethality were compared to those found among 23 non-self-harming, community controls. Adolescents' perceived levels of parental care and control were measured via both adolescents' self-report and independent objective ratings of adolescents' unconstrained descriptions of their parents. Adolescents also completed a standardized psychological symptom checklist. Data from both measurement perspectives indicated that adolescents evidencing self-poisoning behavior perceived their mothers as less caring and more controlling--a parenting style characterized as "affectionless control"--than did the comparison group. Independent ratings of adolescents' descriptions of their parents suggested that those exhibiting self-poisoning also perceived their fathers as less caring. These effects were not moderated by level of psychological symptoms. The findings are consistent with those from previous research showing an association between perceived parental care and control and various self-harming behaviors among adolescents, and highlight the need for research on the potential clinical utility of employing family-based, attachment-promoting psychosocial interventions with this population.

    Purpose Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and BMI. Methods Socioeconomically and racially/ethnically diverse adolescents (N=2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the EAT 2010 (Eating and Activity in Teens) study. Body mass index (BMI) was measured by research staff. Participants’ mean age was 14.6 (SD=2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school. Results BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders. Conclusions Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents’ safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important. PMID:26206444

    To analyze the relationship between different physical activity (PA) domains and sociodemographic, psychological, behavioral and biological factors in Brazilian adolescents. 1,220 adolescents (55.1% female) aged between 10 and 16 years-old participated in this study. The Baecke questionnaire was used to evaluate different PA domains, namely occupational, sports and leisure-time. Socioeconomic status, number of siblings, friendships satisfaction, mother's and father's PA level and previous experience with sports were self-reported. Cardiorespiratory fitness, waist circumference, and somatic maturity were estimated by objective indicators. Linear regression was used for the main statistical analysis. The variables consistently related to all of the PA domains were gender (boys more active), friendship satisfaction (positive with sports and leisure-time PA and negative with occupational PA) and cardiorespiratory fitness (positive). There were also domain-specific relationships for occupational (number of siblings [β = 0.02] and father's PA [β = 0.13]), sport practice (previous experience with sports [β = 0.33], waist circumference [β = 0.01] and somatic maturity [β = -0.12]) and leisure-time PA (chronological age [β = -0.15], mother's PA [β = 0.47] and previous experience with sports [β = 0.17]). The different domains of PA are related to specific variables in adolescence. This information may be helpful in formulating strategies for physical activity promotion, particularly in adolescents from low-to-middle income countries. © 2015 Wiley Periodicals, Inc.

    Adolescent girls in Ghana still face a number of challenges accessing reproductive/sexual health services despite efforts to improve their accessibility. This paper explores the key socio-demographic factors associated with contraceptive use amongst adolescent girls in Ghana using the 2008 Ghana Demographic and Health Survey (GDHS). Data from the 2008 GDHS was analyzed. Socio-demographic variables were selected to assess their interaction with contraceptive use. Multivariable regression analyses were performed. Odds ratios and confidence intervals were computed. Place of residence and marital status were the most important predictors of contraceptive use among sexually active adolescents. Rural residents were less likely to use contraceptives compared to urban residents (OR 0.32, CI 0.12-0.84, p = 0.021) as well as married respondents compared to their unmarried peers (OR 0.27, 95% CI 0.11-0.67, p = 0.005). The accessibility of reproductive/sexual health services needs to be improved and promoted in rural areas and among married adolescent women.

    In a unified framework, the authors estimate whether romantic relationship activities and parental attitudes predict contraception use and consistency, and whether contraception use and consistency predict pregnancy risk among male and females adolescents in the United States. Data on 3717 participants of the first 2 waves of the National Longitudinal Study of Adolescent Health (Add Health) who were sexually experienced in their recent romantic relationship were analyzed to examine how presex activities in the romantic relationship and parental attitudes and communication are associated with contraception choices and how contraception choices are associated with pregnancies. In multivariate logistic regression analysis, only some relationship activities and parental communication about contraception were significant predictors of contraception, and their influence differed by gender. Going out with the partner increased contraception consistency among males (odds ratio, 2.04). Discussing contraception with the partner before having first sex increased the odds of ever using contraception for both genders (2.61 for females and 1.59 for males) and increased the odds of consistent contraception for females (1.505). Discussing contraception with parent increased the odds of consistent contraception among females (1.383). Merely, using contraception was not a significant predictor of the risk of pregnancy, whereas using contraception consistently significantly reduced the odds of getting partner pregnant for males (0.413) and the odds of pregnancy of females (0.343). Contraception and pregnancy education programs should take into account qualities of romantic relationship and emphasize consistent use of contraception and communication about contraception between partners and with parents.

    This study aimed to develop and evaluate the construct validity and reliability of modernized social cognitive measures relating to physical activity behaviors in adolescents. An instrument was developed based on constructs from Bandura's Social Cognitive Theory and included the following scales: self-efficacy, situation (perceived physical environment), social support, behavioral strategies, and outcome expectations and expectancies. The questionnaire was administered in a sample of 171 adolescents (age = 13.6 ± 1.2 years, females = 61%). Confirmatory factor analysis was employed to examine model-fit for each scale using multiple indices, including chi-square index, comparative-fit index (CFI), goodness-of-fit index (GFI), and the root mean square error of approximation (RMSEA). Reliability properties were also examined (ICC and Cronbach's alpha). Each scale represented a statistically sound measure: fit indices indicated each model to be an adequate-to-exact fit to the data; internal consistency was acceptable to good (α = 0.63-0.79); rank order repeatability was strong (ICC = 0.82-0.91). Results support the validity and reliability of social cognitive scales relating to physical activity among adolescents. As such, the developed scales have utility for the identification of potential social cognitive correlates of youth physical activity, mediators of physical activity behavior changes and the testing of theoretical models based on Social Cognitive Theory.

    A cross-sectional study was conducted to determine physical activity, eating behaviour, body weight management knowledge, perception of body image and their association with body weight status of adolescents. Respondents were 360 adolescents, aged between 13 to 14 years, from six randomly selected secondary schools in Kuantan, Pahang. Physical activity, eating behaviour, body weight management knowledge and perception of body image were measured by the Physical Activity Questionnaire for Older Children (PAQ-C), Eating Attitude Test-26 (EAT-26), Weight Management Knowledge Inventory (WMKI) and Contour Drawing Rating Scale (CDRS), respectively. Almost half of the respondents were categorised as having a normal BMI, while 30.3% were severely thin and thin and 20.3% were overweight and obese. Mean physical activity score was 2.06 +/- 0.45 with more males (35.0%) being physically active than females (17.3%). Mean eating behaviour score was 15.41 +/- 10.37, with 27.8% of the respondents being at-risk for eating disorders. Mean weight management knowledge score was 5.35 +/- 1.80, with more females (77.7%) having higher mean scores than males (42.3%). Further, mean discrepancy score for body image perception was 1.24 +/- 0.99, with 78.1% of the respondents being dissatisfied with their current body size. Positive associations were found between eating behaviour (r = 0.28, p < 0.05) and body image (r = 0.35, p < 0.05) with BMI. Respondents with high eating behaviour scores and body image discrepancy scores were more likely to have greater BMI. This study shows the need for healthy eating and body image intervention programmes to prevent overweight and obesity problems among adolescents.

    This study examined how the link between neighborhood poverty and the timing of sexual initiation varies as a function of age, gender, and background characteristics. A sample of N = 2,596 predominately White Canadian adolescents from the National Longitudinal Survey of Children and Youth was used. Sexual initiations occurring between 12 and 15 years old were considered. Results showed that younger adolescent females who lived in poor neighborhoods and who had a history of conduct problems were more likely to report early sexual activity. Peer characteristics partly accounted for this susceptibility. Among adolescent males, no direct neighborhood effects were found, but those who had combined risks at multiple levels appeared more vulnerable. The theoretical and practical implications of these findings are discussed.

    Dietary behaviours and physical activity are modifiable risk factors to address increasing levels of obesity among children and adolescents, and consequently to reduce later cardiovascular and metabolic disease. This paper explores perceptions, attitudes, barriers, and facilitators related to healthy eating and physical activity among adolescent girls in rural South Africa. A qualitative study was conducted in the rural Agincourt subdistrict, covered by a health and sociodemographic surveillance system, in Mpumalanga province, South Africa. Semistructured "duo-interviews" were carried out with 11 pairs of adolescent female friends aged 16 to 19 years. Thematic content analysis was used. The majority of participants considered locally grown and traditional foods, especially fruits and vegetables, to be healthy. Their consumption was limited by availability, and these foods were often sourced from family or neighbourhood gardens. Female caregivers and school meal programmes facilitated healthy eating practices. Most participants believed in the importance of breakfast, even though for the majority, limited food within the household was a barrier to eating breakfast before going to school. The majority cited limited accessibility as a major barrier to healthy eating, and noted the increasing intake of "convenient and less healthy foods". Girls were aware of the benefits of physical activity and engaged in various physical activities within the home, community, and schools, including household chores, walking long distances to school, traditional dancing, and extramural activities such as netball and soccer. The findings show widespread knowledge about healthy eating and the benefits of consuming locally grown and traditional food items in a population that is undergoing nutrition transition. Limited access and food availability are strong barriers to healthy eating practices. School meal programmes are an important facilitator of healthy eating, and breakfast

    This study examined the relationship between socio-demographic factors, screen media time usage, and light, moderate and vigorous activities on weekdays and weekends. Cross-sectional data was collected from 323 Spanish adolescents (mean age 13.59 years) who completed an interview administered recall questionnaire. Structural equation models indicated that male and younger adolescents spent more time on vigorous activities at the weekend, while females and older adolescents showed a greater involvement in light activities both on weekdays and weekends. State school students reported engaging in light and vigorous activities for longer periods than private school students on weekends. TV viewing was negatively linked to vigorous activities during weekdays and to light and moderate activities on weekends. The amount of mobile phone usage, however, was positively linked to light activities during weekdays, but negatively on weekends. The negative relationship between adolescents' use of screen media (TV and mobile phone) and physical activity and its possible displacement, depending on the type of day, added useful comparable knowledge for policies promoting an active lifestyle. Further research is required to provide evidence of the causality in the observed relationships. Copyright © 2010 The Foundation for Professionals in Services for Adolescents.

    Nutritional status, eating behaviors and menstrual function was examined in 23 nationally ranked female adolescent volleyball players using a health/weight/ dieting/menstrual history questionnaire, the Eating Disorder Inventory (EDI), and the Body Shape Questionnaire (BSQ). Nutrient and energy intakes (El) and energy expenditure (EE) were determined by 3-d weighed food records and activity logs. Iron (Fe), vitamins C, B12, and Folate status were assessed using serum and whole blood. Mean El (2248 +/- 414 kcal/d) was less than EE (2815 +/- 306 kcal/d). Mean carbohydrate (5.4 +/-1.0g/kg/d) and protein (1.1+/-0.3g/kg/d) intakes were below recommended levels for highly active women. Mean intakes for folate, Fe, Ca, Mg, and Zn were less than the respective RDAs/DRIs and almost 50% of the athletes were consuming less than the RDAs/DRIs for the B-complex vitamins and vitamin C. Three athletes presented with Fe deficiency anemia (Hb <12 mg/dL), while marginal vitamin B12 status (<200 pg/ml) and vitamin C status (<28 mmol/L) were found in 1 and 4 athletes, respectively. Approximately 1/2 of the athletes reported actively "dieting". Mean BSQ and EDI subscales scores were within the normal ranges; yet, elevated scores on these scales were reported by 26% and 35% of athletes, respectively. Past or present amenorrhea was reported by 17% of the athletes and 13% and 48%, reported past or present oligomenorrhea and "irregular" menstrual cycles, respectively. These results indicate that elite adolescent volleyball players are at risk for menstrual dysfunction and have energy and nutrient intakes that place them at risk for nutritional deficiencies and compromised performance.

  1. Female adolescents' compliance with contraceptive regimens.

    Although today's adolescents have access to a variety of contraceptive options, they remain inconsistent and suboptimal users of these methods. A particularly frustrating problem for those caring for adolescents is the issue of noncompliance with contraceptives, which is an important antecedent of adolescent pregnancy. In the future, new fertility-related developments such as subdermal hormonal implants may reduce the likelihood of noncompliance. For the present, however, systematic monitoring rather than only when noncompliance is suspected is essential in enhancing adolescents' contraceptive compliance.

    Physical activity in youth is associated with adult health. Understanding the prevalence and factors of moderate to vigorous physical activity among adolescents and young adults will guide public health and policy efforts. To describe the current patterns of physical activity and duration among adolescents and young adults and to identify the direction and magnitude of associations between physical activity and income, race/ethnicity, and sex. This cross-sectional secondary data analysis used the self-reported physical activity data of adolescents and young adults from the National Health and Nutrition Examination Survey from 2007 through 2016. This data set is a multistage probability sample of the noninstitutionalized US population and allows estimates that represent the US population. The years 2007 through 2016 were selected because of the consistent physical activity questions during this period. Adolescents and young adults aged 12 to 29 years who responded to the survey were included. Individuals who were underweight were excluded. Data analysis was performed from October 17, 2017, to April 27, 2018. Self-reported physical activity duration and intensity. Of the 9472 participants, 4771 (50.4%) were males, and the weighted mean age (range) was 20.6 (12-19) years. Across all demographic categories, females reported less physical activity than did their male counterparts. White adolescent males were most likely (89.3%; 95% CI, 86.5%-92.1%) and black females aged 18 to 24 years were least likely (45%; 95% CI, 39.0%-51.0%) to report any physical activity. Among those who were active, black males aged 18 to 24 years reported the longest duration of activity (77.9 minutes per day; 95% CI, 66.4-89.3 minutes per day), and black females aged 25 to 29 years reported the shortest duration of activity (33.2 minutes per day; 95% CI, 28.1-38.2 minutes per day). In adjusted models, younger age, white race, and higher income were associated with greater physical activity

    To analyze the association between physical activity, participation in Physical Education classes, and indicators of social isolation among adolescents. This was an epidemiological study based on secondary analysis of data from a representative sample of students (14-19 years) from public high schools (n=4,207). Data were collected through the questionnaire Global School-based Student Health Survey. The independent variables were the level of physical activity and enrollment in Physical Education classes, while the dependent variables were two indicators of social isolation (feeling of loneliness and having few friends). Descriptive and inferential procedures were used in the statistical analysis. Most of the adolescents were classified as insufficiently active (65.1%) and reported not attending Physical Education classes (64.9%). Approximately two in each ten participants reported feeling of loneliness (15.8%) and, in addition, about one in each five adolescents reported have only one friend (19.5%). In the bivariate analysis, a significantly lower proportion of individuals reporting social isolation was observed among adolescents who referred higher enrollment in Physical Education classes. After adjustment for confounding variables, binary logistic regression showed that attending Physical Education classes was identified as a protective factor in relation to the indicator of social isolation 'having few friends,' but only for girls. It was concluded that participation in Physical Education classes is associated with reduced social isolation among female adolescents. Copyright © 2015 Sociedade Brasileira de Pediatria.

    Although activity involvement has been linked to positive youth development, the value that adolescents place on these activities (i.e., how much they enjoy the activities, find them important, and spend time on them) has received less attention. The purpose of the present study was to examine the bidirectional longitudinal association between engagement in valued activities and adolescent positive adjustment (optimism, purpose in life, and self-esteem), as well as investigate a possible underlying mechanism for this link. High school students (N = 2,270, 48.7% female) from Ontario, Canada completed questionnaires annually in grades 10, 11, and 12. Auto-regressive cross-lagged path analyses were conducted over time, controlling for gender, parental education, and academic grades. Greater engagement in valued activities predicted higher optimism, purpose, and self-esteem over time. Importantly, the results did not support an alternate hypothesis of selection effects, in that adolescents who were better adjusted were not more likely than their peers to engage in valued activities over time. We also found that the longitudinal associations between valued activities and positive adjustment may be due partly to an underlying effect of increased positive mood. Thus, engagement in valued activities appears to be important for adolescent positive adjustment, and may help to foster thriving. Communities, educators, and parents should actively support and encourage adolescents to develop valued activities, and seek to ensure that there are ample opportunities and resources available for them to do so.

    The aim of this brief report is to report on the utility of the Theory of Planned Behaviour (TPB) for predicting the physical activity intentions and behaviour of British adolescents from lower-than-average socio-economic backgrounds. A prospective questionnaire design was employed with 197, 13-14 year olds (76 males, 121 females). At time 1 participant completed standard measures of TPB variables. One week later (Time 2), participants completed the Physical Activity Questionnaire for Adolescents (PAQ-A) as a measure of physical activity behaviour. Hierarchical regression analyses showed that attitude and perceived behavioural control jointly accounted for 25% of the variance in intention (p = 0.0001). Perceived behavioural control emerged as the only significant predictor of physical activity behaviour and explained 3.7% of the variance (p = 0.001). Therefore, attitude and PBC successfully predicts intention towards physical activity and PBC predicts physical activity behaviour in British adolescents from lower-than-average socio-economic backgrounds.

    Objective To determine the association between oral contraceptive and condom use, and laboratory‐confirmed sexually transmitted infection (STI) among African‐American adolescent females at a high risk of STI acquisition. Methods A cross‐sectional study of 715 African‐American adolescent females (15–21 years old) was conducted. Data collection included (a) an audio‐computer‐assisted self‐interview and a self‐collected vaginal swab for nucleic acid amplification testing of Trichomonas vaginalis, Chlamydia trachomatis and Neisseria gonorrhoeae. Results The age‐adjusted odds ratio (AOR) indicated a modest protective effect of oral contraceptive use against unprotected vaginal sex (UVS) using a 60‐day recall period (AOR = 0.66; 95% CI 0.43 to 0.99). The age‐adjusted difference in mean frequency of UVS in the past 60 days was non‐significant (p = 0.23) as was condom use at last sex (p = 0.34). The age‐AOR relative to STI prevalence also showed a protective effect (AOR = 0.60; 95% CI 0.36 to 0.98) for those using oral contraceptives. Conclusion The findings suggest that the use of oral contraceptives may not preclude safer sex practices for the prevention of STIs among high‐risk African‐American adolescent females. PMID:17569720

    There is strong evidence that early pubertal timing is associated with adolescent problem behaviors. However, there has been limited investigation of the mechanisms or developmental relationships. The present study examined longitudinal models incorporating pubertal timing, delinquency, and sexual activity in a sample of 454 adolescents (9–13 years old at enrollment; 47% females). Participants were seen for three assessments approximately 1 year apart. Characteristics of friendship networks (older friends, male friends, older male friends) were examined as mediators. Structural equation modeling was used to test these associations as well as temporal relationships between sexual activity and delinquency. Results showed that early pubertal timing at Time 1 was related to more sexual activity at Time 2, which was related to higher delinquency at Time 3, a trend mediation effect. None of the friendship variables mediated these associations. Gender or maltreatment status did not moderate the meditational pathways. The results also supported the temporal sequence of sexual activity preceding increases in delinquency. These findings reveal that early maturing adolescents may actively seek out opportunities to engage in sexual activity which appears to be risk for subsequent delinquency. PMID:21191640

    This study assessed the relationship between physical activity and beverage consumption among adolescents with a population based cross-sectional survey was carried out in the Balearic Islands, Spain (n = 1988; 12-17 years old). Body composition, educational and income level, physical activity (PA), and beverage consumption and energy intake were assessed. Sixty-two percent of adolescents engaged in >300 min/week of PA. Boys were more active than girls, younger adolescents were more active than older counterparts, low parental income was associated with physical inactivity, and time spent watching TV (including, TV, Internet or handheld cellular devices) was inversely associated with PA practice. The average beverage intake of the studied adolescents was 0.9 L/day, higher in boys than in girls. Beverage intake was positively associated with PA practice, and the highest amount of energy intake from beverages was observed in active boys and girls. Most of the studied adolescent population met the PA recommendations. Gender, age, parental income, and time spent watching TV were significant determinants of PA. Type and amount of beverages drunk varied according to gender and PA, and general daily total beverage intake was lower than recommended adequate fluid intake. PA behavior should be considered when analyzing beverage consumption in adolescents.

    The purpose of this study was to examine the impact of age and weight status on adolescents' body dissatisfaction and its change over 20 months in a gender-comparing design. The influence of body image concern on eating concern was also investigated. In a prospective study, 675 male and female adolescents aged 12-16 were assessed using self-report questionnaires on weight, shape, muscularity, and eating concerns. Height and weight measurements were taken by trained personnel. Data were analyzed using structural equation modeling. Analyses of latent means revealed more pronounced weight/shape concern in females than males and more pronounced muscularity concern in males than females. Weight/shape concern increased in females over time, whereas muscularity concern remained stable in both genders. Baseline levels of weight/shape concern could be predicted by age and weight status in females and by weight status in males. The only predictor of change in weight/shape concern was weight status in males. Baseline levels of muscularity concern could be predicted by age in females and by weight status in males. Similar effects were found for changes in muscularity concern in both genders. Increases in weight/shape and muscularity concern were associated with more pronounced eating concern. The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:139-147). © 2016 Wiley Periodicals, Inc.

    This article describes a quasi-experimental evaluation of a community-based, culturally and ecologically tailored HIV prevention intervention for Mexican American female adolescents grounded in the AIDS risk reduction model. A total of 378 Mexican American female adolescents (mean age = 15.2) participated in either the nine-session SHERO's (a female-gendered version of the word hero) intervention or a single session information-only HIV prevention intervention. Assessment data were collected at pretest, posttest, and 2-month follow up. Significant improvements across all time points were revealed on measures of self-esteem, condom attitudes, beliefs regarding a woman's control of her sexuality, beliefs regarding sexual assault, perceived peer norms, and HIV/AIDS and STI knowledge. At posttest SHERO's participants were more likely to carry condoms and to report abstaining from vaginal sex in the previous 2 months; and at 2-month follow up they reported using condoms more often in the preceding 2 months and planned on using them more frequently in the coming 2 months. Findings support the development of community-based adolescent HIV prevention interventions that address culturally specific ecological factors.

    This study aimed at testing a model in which cognitive, dispositional, and social factors were integrated into a single perspective as predictors of gambling behavior. We also aimed at providing further evidence of gender differences related to adolescent gambling. Participants were 994 Italian adolescents (64% Males; Mean age = 16.57). Hierarchical logistic regressions attested the predictive power of the considered factors on at-risk/problem gambling - measured by administering the South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA) - in both boys and girls. Sensation seeking and superstitious thinking were consistent predictors across gender, while probabilistic reasoning ability, the perception of the economic profitability of gambling, and peer gambling behavior were found to be predictors only among male adolescents, whereas parental gambling behavior had a predictive power in female adolescents. Findings are discussed referring to practical implications for preventive efforts toward adolescents' gambling problems. Copyright © 2012 The Foundation for Professionals in Services for Adolescents.

    To assess eating disorders, nutritional status, body composition, and food intake in adolescents presenting with fibromyalgia. In a cross-sectional study, we evaluated the nutritional status (z score of body mass index [ZBMI]), waist circumference, body fat percentage by bioelectrical impedance analysis, symptoms of disordered eating, and possible eating disorders (Kids' Eating Disorders Survey [KEDS]) of 23 female adolescents with fibromyalgia and 23 matched healthy control subjects. Median age for both groups was 15 years. In the fibromyalgia group, the median time for diagnosis was 13.5 months. We did not observe a statistically significant difference between the control and fibromyalgia groups in relation to ZBMI, fat mass percentage, food intake, and symptoms of disordered eating (KEDS). In the fibromyalgia group, there was a significant correlation between fat mass percentage and the total KEDS score (r = .587, p = .003); the same correlation was observed for ZBMI (r = .0778, p < .001). This study verified an absence of nutritional and eating disorders in adolescents recently diagnosed with fibromyalgia that, in addition to the correlation between adiposity indexes and KEDS total score, emphasizes the importance of nutritional and body composition assessment, allowing an early and adequate nutritional intervention.

    Background Sex trafficking has been a long-standing concern in Nepal. Very little has been achieved, however, in terms of actual reduction in the number of victims despite numerous anti-sex trafficking programs. This situation may be attributable to a lack of empirical evidence upon which to formulate anti-sexual trafficking interventions. This study aimed to assess sex trafficking-related knowledge, awareness and attitudes, and factors associated with sex trafficking awareness and attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns among adolescent female students in Nepal. Methods A cross-sectional study was conducted between August–September 2013 among 292 adolescent female students (>10 years old) using systematic random sampling from three high schools in Sindhupalchowk district, Nepal. As an initial step, descriptive analyses were employed to characterize the data and multivariate logistic regression analyses were used to explore factors associated with sex trafficking awareness and related attitudes. Results Seventy-six percent of sampled students reported that they were aware of sex trafficking and 94.6% indicated media (i.e., radio or television) as the primary sources of their knowledge. Fifty-one percent mentioned relatives/friends as mediators of sex trafficking, 60.4% reported promise for better jobs as the primary attraction behind sex trafficking, and 48.6% mentioned adolescent females as the most vulnerable group for sex trafficking. Over half (56.8%) of the respondents had positive attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns. Age (OR = 3.38, 95% CI:2.51–4.55), parents’ occupation (OR = 3.89, 95% CI:1.58–9.58), and having a radio/TV at home (OR = 6.67, 95% CI:3.99–9.54) were significantly associated with awareness, whereas being younger (OR = 0.67, 95% CI:0.55–0.79) and having joint-family (OR = 2.67, 95% CI:1.49–4.80) were significantly associated with

    Adolescent African-American females are disproportionately impacted by HIV, thus there is a clear need to understand factors associated with increased HIV-risk behaviors among this vulnerable population. We sought to explore the association between a dopamine D4 receptor gene (DRD4), a genetic marker associated with natural variations in rewarding behaviors, and self-reported alcohol-use and sexual risk-behaviors, while controlling for other known correlates of risk-taking such as impulsivity, sensation seeking, and peer norms among a group of high-risk African American female adolescents to evaluate whether this biological factor enhances our understanding of patterns of risk in this vulnerable group.

    To assess the prevalence and clustering patterns of cardiometabolic risk factors among low-income, female adolescents. Cross-sectional study involving 196 students of public schools (11-19 years old). The following risk factors were considered in the analysis: excess weight, central obesity, dyslipidemia, high blood pressure, and high fasting glucose. The ratio between observed and expected prevalence and its confidence interval were used to identify clustering of risk factors that exceeded expected prevalence in the population. The most prevalent risk factors were dyslipidemia (70.9%), and central obesity (39.8%), followed by excess weight (29.6%), and high blood pressure (12.8%). A total of 42.9% of adolescents had two or more risk factors, and 24% had three or more. Excess weight, central obesity, and dyslipidemia were common risk factors in the clustering patterns that showed higher-than-expected prevalence. Clustering of risk factors (≥ two factors) among the adolescents showed considerable prevalence, and there was a non-casual coexistence of excess weight, central obesity, and dyslipidemia (mainly low HDL-cholesterol).

    2016-05-01

    Adolescents are recommended to achieve ≥ 60 min/day of moderate-to-vigorous physical activity (PA) and ≤2 h/day of screen time (ST). This study examined the relationships between the use of social networking sites (SNSs) and adherence to PA and ST recommendations in a large sample of Canadian adolescents. This cross-sectional school-based survey included a representative sample of 9388 students in grades 7 to 12 across Ontario, Canada. After adjustment for several confounding variables, results showed that male adolescents who use SNSs for fewer hours (≤ 1 h/day) had greater odds of adherence to PA and to both PA and ST recommendations concurrently, while those who use it for more hours (≥ 3 h/day) had lower odds of adherence to the ST recommendation. Female adolescents who use SNSs for more hours had lower odds of adherence to the ST recommendation (use of SNSs ≥ 2 h/day) and to both PA and ST recommendations concurrently (use of SNSs ≥ 5 h/day). Heavy use of SNSs has a negative influence on the adherence to the ST recommendation in both males and females; however, infrequent use of SNSs was related to the adherence to the PA recommendation and concurrent adherence to both recommendations in males only.
