    Objectives: This study was designed to evaluate bone mineral density (BMD) in healthy female Brazilian adolescents in five groups looking at chronological age, bone age, and pubertal breast stage, and determining BMD behavior for each classification. Methods: Seventy-two healthy female adolescents aged between 10 to 20 incomplete years were divided into five groups and evaluated for calcium intake, weight, height, body mass index (BMI), pubertal breast stage, bone age, and BMD. Bone mass was measured by bone densitometry (DXA) in lumbar spine and proximal femur regions, and the total body. BMI was estimated by Quetelet index. Breast development was assessed by Tanner’s criteria and skeletal maturity by bone age. BMD comparison according to chronologic and bone age, and breast development were analyzed by Anova, with Scheffe’s test used to find significant differences between groups at P≤0.05. Results: BMD (g·cm-2) increased in all studied regions as age advanced, indicating differences from the ages of 13 to 14 years. This group differed to the 10 and 11 to 12 years old groups for lumbar spine BMD (0.865±0.127 vs 0.672±0.082 and 0.689±0.083, respectively) and in girls at pubertal development stage B3, lumbar spine BMD differed from B5 (0.709±0.073 vs 0.936±0.130) and whole body BMD differed from B4 and B5 (0.867±0.056 vs 0.977±0.086 and 1.040±0.080, respectively). Conclusion: Bone mineralization increased in the B3 breast maturity group, and the critical years for bone mass acquisition were between 13 and 14 years of age for all sites evaluated by densitometry.

    To investigate sociodemographic factors associated with adolescent females ages 14-16 years having children fathered by males age 20 years or older and identify differences in correlates across rural, urban, and border areas. The method section was a cross-sectional study using Texas birth record data. From 2000 through 2004, there were 29,186 births to adolescent females aged 14-16 years with valid paternal age. Prevalence of and adjusted odds of paternal age of 20 years or older were identified by paternal and maternal factors. The Results section Having both parents born outside of the U.S. was associated with a 5.29 (95% CI: 4.82, 5.80) times increase in the odds of paternal age of 20 years or older as compared to having both parents born in the U.S. Parental place of birth was associated with greater odds of paternal age of 20 years or older in urban areas compared to rural or border areas. Compared to those with average or high educational attainment relative to age, low educational attainment relative to age was associated with an increase in the odds of paternal age of 20 years or older. This association was present whether maternal or paternal educational attainment was low relative to age. Messages are needed to help adolescent females avoid pregnancy with adult males. In addressing this specific prevention challenge, it is important to consider maternal/paternal place of birth and its association with adolescent births with adult males.

  3. Age and adolescent social stress effects on fear extinction in female rats.

    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.

  4. Self-esteem and social anxiety in an adolescent female eating disorder population: age and diagnostic effects.

    2013-01-01

    This study explored symptoms of social anxiety and multidimensional self-esteem in a clinical, adolescent female eating disorder population. Using self-report measures, data from 344 females revealed significant negative relationships between dimensions of self-esteem and social anxiety. A diagnostic difference emerged, with the restricting subgroup reporting significantly higher perceived physical appearance and global self-worth than those with binge/purge symptoms or bulimia nervosa. No significant age differences or age by diagnosis interaction effects emerged. These findings suggest that in clinical samples of adolescent eating disorders, self-esteem and social anxiety share a significant inverse relationship and seem to remain fairly constant across adolescence.

    We aimed to determine the association between household food insecurity (HFI) and the co-occurrence of overweight and anemia among women of reproductive age in the Mexican population. We analyzed data on 4,039 nonpregnant female adolescents (15-19 years) and 10,760 nonpregnant adult women of reproductive age (20-49 years) from the 2012 National Health and Nutrition Survey of Mexico. The survey uses a two-stage sampling design, stratified by rural and urban regions. The Latin American and Caribbean Food Security Scale was used to assess HFI. We assessed overweight and obesity in women based on World Health Organization classifications for body mass index, and BMI-for-age Z-scores for female adolescents, and defined anemia as an altitude-adjusted hemoglobin (Hb) concentration < 120 g/L based on measurement of capillary Hb concentrations. In multiple logistic regression models adjusting for potential confounding covariates, HFI was not associated with the co-occurrence of anemia and overweight among female adolescents. The adjusted odds of women of reproductive age from mildly and moderately food-insecure households, respectively, experiencing concurrent anemia and overweight were 48% (OR: 1.48; 95% CI: 1.15, 1.91) and 49% (OR: 1.49; 95% CI: 1.08, 2.06) higher than among women from food-secure households. Severe HFI was not associated with concurrent overweight and anemia among female adolescents or women. HFI may be a shared mechanism for dual forms of malnutrition within the same individual, simultaneously contributing to overconsumption and dietary inadequacy.

  10. Female fecundity and age.

    DeCherney, A H; Berkowitz, G S

    1982-02-18

    Studies have shown that fertility (defined as number of live births) declines with age in women. However, it is not known to what extent other factors, such as male reproductive capacity and coital patterns affect this decrease. Male fecundity may also decline with age, and coital frequency is believed to decline with length of marriage. All these factors are closely related to the woman's age. The effects of male fecundity and coital frequency can be eliminated in evaluating female fecundity by studying patients who have received artificial insemination and restricting the group to those with azoospermic husbands. In 2193 patients drawn from 11 centers in France that offer artificial insemination with frozen donor semen, women over 30 exhibited a marked decline in fecundity. The cumulative success rate after 12 cycles of insemination was 73% for those under 25, 74.1% for the 26-30 age group, 61.5% for those 31-35 years old, and 53.6% for those over 35 years. The difference in fecundity with age was consistent across the centers, an important factor to note since the mean success rate per cycle differed considerably among the participating centers. The decreased fecundity in women over 30 may be attributed to gynecologic diseases, or effects of age on the incidence of tubal deciliation and occurrence of ovulatory disorders. New guidelines for counseling on reproduction may be needed for women over 30. Currently, counseling regarding reproduction and maternal age is limited to increased risks of Down's syndrome and other genetic abnormalities and risks of spontaneous abortion and perinatal deaths. The age of a woman should be considered when deciding when to start an infertility workup or stop treatment for infertility, and in selecting appropriate candidates for tubal surgery and in vitro fertilization. There is also a need to reevaluate individual and societal goals regarding childbearing to accommodate women's desires to have both a family and a career.

    Feeding in infancy is necessary to allow proper growth and development. Health of these early stages of life may influence the development of many diseases in the future (atherosclerosis, osteoporosis, hypertension, obesity ...). Furthermore habits set in childhood will endure throughout life. Therefore, getting adequate dietary and health patterns in childhood is vital. In adolescence occur a number of changes: rapid growth, development of secondary sexual characteristics, changes in body composition, ... that will be a challenge when getting or keeping that adequate feeding and habits. In female population requirements of different micronutrients are increased (mainly iron) and also higher energy requirement than in later stages of life occurs. However, adolescents are the main population at risk for developing eating disorders, which can pose serious problems to meet these nutritional requirements to achieve optimal development. These features and others, such as pregnant adolescents, are what make them a population that should be taken special care from nutritional point of view.

    Adolescence is usually defined as the period of rapid physical and psychological growth and development occurring during the second decade of life. After the introduction about the physiology of puberty and menstrual cycle, the major problems in female adolescents are discussed: delayed puberty, hypo and hypergonadotropic hypogonadism, causes of primary and secondary amenorrhea, menstrual irregularity, dysfunctional uterine bleeding, dysmenorrhea, breast disorders, hirsutism, acne. Finally, adolescent pregnancy prevention and contraception are discussed. The Authors want to stress the importance of the endocrinological and gynaecological disorders in female adolescents and their impact on the psychological and emotional development at this very delicate age.

    2011-02-01

    Peak bone mass (PBM) is a negative predictor of osteoporosis and lifelong fracture risk. Because osteoporosis is such a prevalent disease with life-threatening consequences, it is important to try to maximize PBM. Adolescence is a critical period for bone acquisition. This article 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, effects of physical activity, and nutritional contributions are included, with a focus on the adolescent athlete. Emphasis is placed on the importance of appropriate energy availability in this age group. We also review prevention and treatment strategies for the female athlete triad (ie, the inter-relationship of decreased energy availability, menstrual irregularity, and low bone density) in adolescents and athletic women. Recommendations for maximizing bone density in both male and female adolescents are discussed.

    2001-01-01

    Young female offenders (n = 29) and female high school students (n = 47) were compared in terms of delinquent behavior and relationships with their best female friend and peer group. Young offenders exhibited significantly more delinquent behavior than did high school students in the past year. Delinquents and nondelinquents did not significantly differ in amount of companionship, conflict, help, security, and closeness with their best female friend, and amount of trust, alienation, and perceived intimacy in their peer group. Less communication and more perceived peer pressure in the peer group distinguished delinquent females from nondelinquent females. Perceived peer pressure significantly predicted delinquent behavior in female adolescents. In short, friendships of delinquent and nondelinquent female adolescents are essentially similar despite higher levels of peer pressure among delinquents.

    2009-09-01

    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.

    2016-12-01

    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.

    In this study, we determined the specificity of a low frequency taekwondo training programme on physical fitness levels in adolescent females who receive limited physical education instruction (i.e. 2 days per week). Major components of physical fitness assessed were: skeletal muscle fitness (hand grip strength, bent arm hang, standing long jump, and isokinetic strength), flexibility (sit-and-reach test), speed and agility (10 × 5-m shuttle run), and cardiovascular fitness (VO(2max) and 20-m shuttle run). Changes in body composition were also assessed (dual X-ray absorptiometry, DXA). Participants were divided into two groups, a taekwondo training group (n = 21), which trained 50 min a day, 2 days per week for 12 weeks, and a control group (n = 10). Taekwondo training improved isokinetic strength, standing long jump, and sit-and-reach performance. Body fat mass and percent body fat were reduced. No changes in grip strength, bent arm hang time, speed and agility, or cardiorespiratory fitness were observed. Results indicate that low frequency taekwondo training in adolescent females produces beneficial changes in skeletal muscle fitness, flexibility, and body composition in a relatively short period of time. Consequently, this specific type of training can be useful to female adolescents in structured school environments where physical education classes are limited and there is little free time for physical activity.

    The aims of the study were to determine (1) whether the presence of High blood pressure (HBP) states in the youth associate a steeper rate of age-related change in arterial geometrical and wall properties with respect to subjects with no previous cardiovascular risk factor (CRF) exposure, (2) in which parameters and in what magnitude, and (3) the existence of a gender-related difference in the impact of this condition on arterial properties. 300 individuals (mean/range: 15/4-29 years; 133 females) were included. Two groups were assembled: (1) Reference: nonprevious exposure to traditional CRF and (2) HBP: subjects with arterial hypertension and/or elevated blood pressure (BP) levels during the study. Additionally, HBP subjects were separated in BP-related subgroups. Measured parameters were (1) central (aortic) arterial BP and aortic pulse wave analysis parameters, (2) carotid and femoral artery local (pressure-strain elastic modulus) and regional (pulse wave velocity; PWV) stiffness, and (3) arterial diameters and carotid intima-media thickness (CIMT). Age-related changes in these parameters (absolute values and z-scores) were explored by obtaining simple linear regression models for each group. HBP presented a steeper rate of change (accelerated vascular aging; VA) for most of the parameters assessed, mainly in central (aortic) hemodynamics. VA increased as the HBP level got higher. Both males' and females' aging rates were affected by this condition, but females presented a more marked relative age-related increase with HBP exposure. HBP states in the youth gradually associate accelerated VA, with a progressive hemodynamic-structural-functional onset of damage, with females presenting a more marked relative HBP-associated arterial repercussion.

    Background: 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. Purpose: 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. Study Design: Cohort study; Level of evidence, 3. Methods: 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. Results: 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. Conclusion: 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. PMID:28210658

    PubMed

    Blythe, M J; Rosenthal, S L

    2000-03-01

    Health care providers must recognize the specific challenges and rewards of providing services for adolescents. Quality care begins with the establishment of trust, respect, and confidentiality between the health care provider and the adolescent. Data suggest that the normal age for beginning puberty is decreasing, which has important clinical, educational, and social implications. The health care provider should be aware of the broad range of potential sexual behaviors involving adolescents, as well as the teen's acceptance of such behaviors, often dictated by age, gender, culture, and education. When providing gynecologic care to adolescent girls, the physician should not only provide contraception and screen for sexually transmitted diseases but should contribute to the development of the patient's sexual health. Especially when providing care for the younger teen, the health care provider must focus on involving a member of the family or another significant adult to provide needed support and guidance. Anticipatory guidance for parents should focus on assessing their parenting styles and promoting supervision. Although parents should strive to maintain open communication with their adolescents, they may not accurately estimate the sexual activity of and the sexual risk for their teenage children. Parents need to be encouraged to consider the implications of their own sexual behaviors. The provider should attempt to foster a comfortable environment in which youth may seek help and support for appropriate medical care while reserving the right to disclose their sexual identity when ready. Health care professionals cannot exclude heterosexual behavior on the basis that a young woman self-identifies as homosexual. Her reported sexual behaviors may not indicate her sexual orientation. Self-definition of sexual orientation is a dynamic process including factors such as fantasies, desires, and behaviors. Self-definition of sexual identity is affected by individual

    Background: Gender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females. Methods: A total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2nd or 3rd days, 14th days, and 28th days, respectively. Serum estradiol (E2) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above. Results: In young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (χ2 = 6.35, P = 0.042). The vision during the 14th and 28th day was higher compared to that on the 2nd or 3rd days (P = 0.021). Serum E2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E2 levels reached its maximum value on the 14th day and the minimum value on the 2nd or 3rd day. Conclusions: In adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage. PMID:25698200

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.

    This study examined sleep patterns in female adolescents with chronic musculoskeletal pain. Twenty-six participants with chronic musculoskeletal pain completed questionnaires during their clinic visit, and three 24-Hour Sleep Patterns Interviews during the following 2 weeks. Compared to normative data (Acebo & Carskadon, 2002), adolescents with chronic pain reported similar total sleep time (TST) and bedtimes. However, study participants reported significantly longer sleep onset latency, more night wakings, a later morning wake time, and more symptoms of daytime sleepiness. Pain improved after sleep for 27% of the study sample, and was associated with longer TST. Finally, depression and anxiety were related to daytime sleepiness, but not total sleep time or sleep onset latency. Female adolescents with chronic pain either may be more sensitive to the chronic sleep debt that is common in this age group, or they may experience underlying physiological sleep disrupters (e.g., periodic limb movement disorder) or sleep abnormalities (e.g., alpha-delta intrusions) not measured in this study. Additional research is needed to examine the complex relation between sleep and chronic musculoskeletal pain.

    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

    Although pregnant adolescents are at high risk of poor birth outcomes, the majority of adolescents go on to have full-term, healthy babies. Data from the National Longitudinal Study of Adolescent Health, a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States who were surveyed from 1994-1995 through 2008, were used to examine the epidemiology of preterm birth and low birth weight within this population. Outcomes of pregnancies were reported by participants in the fourth wave of data collection (when participants were 24-32 years of age); data were compared between female participants who reported a first singleton livebirth at less than 20 years of age (n = 1,101) and those who were 20 years of age or older (n = 2,846). Multivariable modeling was used to model outcomes; predictors included demographic characteristics and maternal health and behavior. Among black adolescents, low parental educational levels and older age at pregnancy were associated with higher birth weight, whereas low parental educational levels and being on birth control when one got pregnant were associated with higher gestational age. In nonblack adolescents, lower body mass index was associated with lower birth weight, whereas being unmarried was associated with lower gestational age. Predictors of birth outcomes may differ by age group and social context.

    1983-01-01

    A questionnaire survey on sex knowledge of 930 female vocational students (17-18 year olds) was done to assess future needs in sex education. Main points in the questionnaire were sex upbringing and education received; peer groups, couple and contraceptive behavior; and attitude to family and family planning. Socioeconomic factors, parents' occupation, and size of residence were considered. Results showed: 70.4% had some kind of sex upbringing before age 12; 24.5% after age 12. Whereas up to 80% wanted sex education from parents, only about 55% actually received this (mothers mostly); 80% of actual sex information came from books and TV. Peers proved closer to the girls in confidence than parents. Although teachers were 3rd in line to provide actual sex education they were last as persons desired by the girls to provide this. Nearly 60% of the subjects desired more information in the areas of love and marriage, sex in adolescence, effects and side effects of the pill, general contraceptive methods and sex behavior. Conclusions from the survey point to the need to start sex education at an early age and extend it into adolescence and beyond; it should be direct, continuous and goal-oriented. Teenagers desire interpersonal dialogue with concerned adults. There should be cooperation in sex education between parents, teachers, and youth organizations. Teachers are insufficiently prepared to assume the role as sex educator. Teenagers need more factual information on conscious family planning and contraceptive methods.

  6. Age and sex differences in reward behavior in adolescent and adult rats.

    Hammerslag, Lindsey R; Gulley, Joshua M

    2014-05-01

    Compared to adults, adolescents are at heightened risk for drug abuse and dependence. One of the factors contributing to this vulnerability may be age-dependent differences in reward processing, with adolescents approaching reward through stimulus-directed, rather than goal-directed, processes. However, the empirical evidence for this in rodent models of adolescence, particularly those that investigate both sexes, is limited. To address this, male and female rats that were adolescents (P30) or adults (P98) at the start of the experiment were trained in a Pavlovian approach (PA) task and were subsequently tested for the effects of reward devaluation, extinction, and re-acquisition. We found significant interactions between age and sex: females had enhanced acquisition of PA and poorer extinction, relative to males, while adolescents and females were less sensitive to reward devaluation than male adults. These results suggest that females and adolescents exhibit reward behavior that is more stimulus-directed, rather than goal-directed.

    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.

    Congenital breast and genital tract anomalies are seen frequently in the care of children and adolescents. Breast and internal gynecologic anomalies more often present in adolescence than in early childhood. Management is best delivered through a multidisciplinary team approach. Carefully timed surgical intervention is of importance to optimize psychological, aesthetic and functional outcomes. An understanding of the female breast and genital tract embryology and anatomy is important for a meticulous clinical examination and appropriate surgical treatment. This article will review the normal embryology and anatomy of the adolescent female breast and genital tract.

    Approaches for the development of preclinical models of depression extensively use adult and male animals owing to the discrepancies arising out of the hormonal flux in adult females and adolescents during attainment of puberty. Thus the increased vulnerability of females towards clinical depression and anxiety-related disorders remains incompletely understood. Development of clinical models of depression in adolescent females is essential in order to evolve effective treatment strategies for adolescent depression. In the present study, we have examined the anxiety and depressive-like profiles in a putative animal model of childhood depression, the Wistar Kyoto (WKY) rat, during early adolescence (∼postnatal day 30) and mid-adolescence (∼postnatal day 40). Female adolescent WKY rats, tested on a series of behavioural tests modelling anxiety- and depressive-like behaviours with age-matched Wistars as controls, demonstrated marked differences during early adolescence in a strain- and age-specific manner. Anxiety indices were obtained from exposure to the elevated plus maze, where social communication vide 50-kHz ultrasonic vocalizations was also assessed, while immobility and other parameters in the forced swim test were screened for depressive-like profiles. Sucrose preference, used as a measure of anhedonia in animals, was lower in WKYs at both ages tested and decreased with age. Anxiety-related behaviours were prominent in WKY rats only during early adolescence. WKY female rats are anxious during early adolescence and exhibit anhedonia as a core symptom of depression during early- and mid-adolescence, thus indicating that inclusion of female animals in preclinical trials is essential and will contribute to gender-based approaches to diagnosis and treatment of adolescent depression in females.

    Objective 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. Hypotheses: 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). Methods 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. Results 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. Conclusions 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

    2009-06-01

    This study investigated the patterns of spirituality, gender, and age in cybergossip practices among Nigerian adolescents. The study utilized a descriptive survey method. Five hundred thirty adolescent students, randomly selected from four major cities in Nigeria, participated in the study. Their age range was 16 to 21. General Spirituality and Gossip Purpose scales were used to collect data from the participants. Data collected were subjected to t test statistics. Findings showed that there is no significant difference in the cybergossiping practices of adolescents based on their levels of spirituality. This reveals that spirituality is not an inhibiting factor in cybergossiping practices among the adolescents. However, there is significant difference between male and female youths in their cybergossiping practices. The results showed that females are more likely than males to be involved in cybergossiping activities. There is also significant difference between early and late adolescents' cybergossiping activities. The implication is that gossip and cybergossip is a natural tendency that involves communicative expression with a pleasure-seeking purpose. It is a habit that excludes no one despite spiritual, gender, or age factors. Therefore, this behavior should be positively directed away from abusive computing and communication. This work is unique because of the need for parents, guardians, and psychologists to design measures to identify and manage various moderating variables in children's computing practices for optimal positive outcomes.

    This study addresses the epidemiology of injuries in adolescent male and female soccer players in Germany. Therefore, the purpose of the study was to analyse the injuries in male and female youth soccer players in Germany. This study was designed as a cross-sectional web-based survey. From March until December 2011 we investigated 1110 soccer players (male n = 841; female n = 269) aged 12 - 19 years (15.0 ± 2.0 years) from 60 clubs in Southern Germany. A total of 664 (79 %) of the 841 boys and 67 (25 %) of the 269 girls reported being injured due to soccer. The total number of injuries was 2373. Respectively the frequency of injury was 2.85 in boys and 7.10 in girls. The lower extremities were affected in 70 % of all reported cases. Strains were the most common injuries in the lower and upper extremities (35 %). The boys reported in 51.5 % of all injuries that the injury was non-contact in nature. In contrast, 52.1 % of the injuries in girls were reported as contact injuries. Similar amounts of injuries were observed in training versus games for both genders. Prevention procedures, such as a thorough warm-up, should be implemented before every game and training to reduce the risk of injury.

Participants included 44 adolescents parented by same-sex female couples and 44 adolescents parented by opposite-sex couples, matched on demographic characteristics and drawn from a national sample. On both self-reported and peer-reported measures of relations with peers, adolescents were functioning well, and the quality of their peer relations was not associated with family type. Regardless of family type, adolescents whose parents described closer relationships with them reported higher quality peer relations and more friends in school and were rated as more central in their friendship networks.

    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.

    2014-03-01

    We present the first longitudinal data on cognitive and motor aging in the chimpanzee (Pan troglodytes). Thirty-eight adult female chimpanzees (10-54 years old) were studied. The apes were tested longitudinally for 3 years in a modified Primate Cognition Test Battery, which comprised 12 tests of physical and social cognition. The chimpanzees were also administered a fine motor task requiring them to remove a steel nut from rods of various complexity. There was little evidence for an age-related decline in tasks of Physical Cognition: for most tasks, performance was either stable or improved with repeated testing across age groups. An exception was Spatial Memory, for which 4 individuals more than 50 years old experienced a significant performance decline across the 3 years of testing. Poorer performance with age was found in 2 tasks of Social Cognition, an attention-getting task and a gaze-following task. A slight motor impairment was also observed, with old chimpanzees improving less than younger animals with repeated testing on the simplest rod. Hormonal status effects were restricted to spatial memory, with non-cycling females outperforming cycling females independently of age. Unexpectedly, older chimpanzees were better than younger individuals in understanding causality relationships based on sound.

    Psychopathy-related paralimbic and limbic structural brain abnormalities have been implicated in incarcerated adult and adolescent male samples. However, there have been few neuroimaging studies of psychopathic traits in females in general and no studies from incarcerated female youth in particular. Here we present the first study to examine the relationship between brain gray matter volumes and psychopathic traits (assessed using the Psychopathy Checklist-Youth Version [PCL-YV]) in a sample of maximum-security incarcerated female adolescents (N = 39; mean age = 17.6 years). Consistent with male samples, regional gray matter volumes were negatively related to psychopathic traits in female youth offenders in limbic and paralimbic areas, including orbitofrontal cortex, parahippocampal cortex, temporal poles, and left hippocampus. These results provide evidence that psychopathic traits manifest similar neural abnormalities across sex and age. PMID:24682609

    The study examined the associations between female adolescents' individuation during mid-adolescence and their adjustment two years later to leaving home for mandatory military service. Forty nine daughter-mother dyads participated. Individuality and connectedness during adolescent-mother interactions were observed at age 16. Two years later girls reported on their psychological distress and negative expectations regarding the upcoming conscription, and both daughters and mothers reported on maternal support of daughters' autonomy. Controlling for these concurrent perceptions, girls' higher connectedness was associated with less psychological distress and their higher individuality in the context of low to medium connectedness was related to more negative expectations. These findings contribute to the literature on home leaving by showing that early individuation may play a role in female adolescents' adjustment to this transition.

    Purpose The purpose of this qualitative study was to assess the coping styles of female adolescent cancer patients regarding potential loss of fertility. Expectations and desires for the future, coping styles in typical adolescence, and coping styles when faced with potential loss of fertility due to cancer treatment are discussed. Methods Female adolescents diagnosed with cancer aged 12–18 years at study (N=14) were administered a 10-item values clarification tool to pilot test the readability and relevance of the items on reproductive concerns, followed by a cognitive debriefing interview asking participants how they would respond to each item. These qualitative responses were assessed for coping style type using the constant comparative approach. Results All adolescent participants reported having a strong desire for biological children in the future. Reactions to questions regarding the loss of fertility fell into two categories of coping styles: emotion-focused coping or problem-focused (engagement) coping. Within emotion-focused coping, there were three distinct styles: externalizing attribution style, internalizing attribution style, and repressive adaptation. Problem-focused coping adolescents displayed optimism. Conclusion Successful interventions aimed at promoting adaptive coping styles should seek to uncover adolescents' values about future parenthood and reproduction. Development of an age-appropriate assessment to stimulate dialogue regarding fertility and initiate an adolescent's cognitive processing of potential fertility loss is warranted. PMID:23781403

    According to the 1982 National Survey of Family Growth, 46% women aged 15-19 had experienced premarital intercourse. Projections based on this study show that by their 20th birthdays, 70% of all women in the US will have experienced premarital intercourse. This article examines the effects of various factors on the likelihood that teenagers will become sexually active. Data for this study were taken from the National Survey of Family Growth, Cycle III. Fieldwork was done in 1982 and included interviews of 7969 women aged 15-44. Data include background characteristics, measures of fertility and contraception, measures of fecundity and birth expectations, use of family planning services, and the respondent's marital history. The study concludes that family stability (intact families), Hispanic ethnicity, high parental education, religious affiliation, regular church attendance, and reproductive education decrease the occurrence of 1st intercourse. Other factors characterize an environment that is unstable and unstructured and has a liberalizing influence upon 1st intercourse. Teens from broken homes, blacks, and the lower social classes are more likely to initiate intercourse. Geographic factors have a very small influence upon the initiation of sexual activity among teens. Similar patterns of influence appear regarding contraceptive use. The same factors that encourage stability, such as high father's education, Catholic or Jewish religious affiliation, religious attendance, and reproductive instruction shift the odds in favor of contracepted rather than noncontracepted sex. Family instability and low social class increase the risk that 1st intercourse will not be contracepted. Providing too much sex education, such as instruction on birth control, may actually contribute to the leniency of the environment, although the authors find no evidence that school-based birth control instruction increases the chances that contraceptives will be used.

    OBJECTIVE: To describe the prevalence of headache and its interference in the activities of daily living (ADL) in female adolescent students. METHODS: This descriptive cross-sectional study enrolled 228 female adolescents from a public school in the city of Petrolina, Pernambuco, Northeast Brazil, aged ten to 19 years. A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05. RESULTS: After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001); interference in ADL (p<0.001); medication use (p<0.001); age (p=0.045) and seek for medical care (p<0.022). CONCLUSIONS: The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance. PMID:25119759

    This article examines the health implications of new age technology use among adolescents. As Internet prevalence has increased, researchers have found evidence of potential negative health consequences on adolescents. Internet addiction has become a serious issue. Pornography is now easily accessible to youth and studies have related pornography with several negative health effects. Cyberbullying has become a large problem as new age technologies have created a new and easy outlet for adolescents to bully one another. These technologies are related to increased morbidity and mortality, such as suicides due to cyberbullying and motor vehicle deaths due to texting while driving.

    The purpose of this study was to elucidate the etiological pathways towards substance use and risky sexual behavior in female adolescent substance abusers. The study had three aims: (1) to determine the relations between behavioral dysregulation, negative affectivity, and childhood victimization with substance use and risky sexual behavior, (2) to determine whether these relations are mediated by internalizing symptomatology, antisocial behavior, and affiliating with an adult boyfriend; and (3) to determine whether age of menarche moderates the relation between the mediating variables and substance use and risky sexual behavior. Multiple behavioral, psychiatric interview, and self-report measures were used to index behavioral dysregulation, negative affectivity, childhood victimization, internalizing symptomatology, antisocial behavior, affiliation with adult boyfriends, substance use, and risky sexual behavior in 125 substance abusing female adolescents and 78 controls between the ages of 14-18 years. Structural equation modeling was used to determine the etiological pathways. Results indicated that behavioral dysregulation, negative affectivity, and childhood victimization were related to substance use and risky sexual behavior. Age of menarche was significantly correlated with affiliation with an older boyfriend and risky sexual behavior. Antisocial behavior mediated the associations between behavioral dysregulation, negative affectivity and childhood victimization with substance use and risky sexual behavior. Affiliation with an adult boyfriend was directly associated with substance use involvement and accounted for the relationship between chronological age and risky sexual behavior. Finally, late menarche enhanced the association between internalizing symptomatology and substance use involvement. The results highlight the importance of behavioral dysregulation, negative affectivity, and childhood victimization in predicting substance use and risky sexual

    Egypt assessed tobacco use among young people and adults through implementation in 2009 of the Global Youth Tobacco Survey (GYTS) among school students aged 13-15 years and the nationally representative Global Adult Tobacco Survey (GATS) among adults aged 15+ years. Both surveys employed cluster sampling to produce nationally representative samples and used standard core questionnaires with optional, country-specific questions. The results indicated that a higher percentage of adolescent girls in Egypt used tobacco than did adult females. Overall, 3.8% of girls aged 13-15 years used some form of tobacco compared with 0.6% of women aged 15+ years. Adolescents were over 14 times more likely than adult women to currently smoke cigarettes and 11 times more likely to smoke waterpipes. Moreover, the prevalence of cigarette smoking among adolescent girls had increased from 1.4% in the 2005 GYTS to 2.8% in 2009, indicating that social and cultural norms may be changing.

    Consistent condom use among high risk groups such as female sex workers (FSWs) remains low. Adolescent female sex workers are especially at higher risk for HIV/STI infections. However, few published studies have compared the sexual risk negotiations among adolescent, emerging adult, and older age groups or the extent a manager's advice about condom use is associated with an FSW's age. Of 1,388 female bar/spa workers surveyed in the southern Philippines, 791 FSW who traded sex in the past 6 months were included in multivariable logistic regression models. The oldest FSWs (aged 36–48) compared to adolescent FSWs (aged 14–17) were 3.3 times more likely to negotiate condoms when clients refused condom use. However, adolescent FSWs received more advice from their managers to convince clients to use condoms or else to refuse sex, compared to older FSWs. Both adolescent and the oldest FSWs had elevated sexually transmitted infections (STIs) and inconsistent condom use compared to other groups. Having a condom rule at the establishment was positively associated with condom negotiation. Factors such as age, the advice managers give to their workers, and the influence of a condom use rule at the establishment need to be considered when delivering HIV/STI prevention interventions.

    Substantial evidence exists for 3- and 4-factor models of psychopathy underlying patterns of covariation among the items of the Psychopathy Checklist-Revised (PCL-R) in diverse adult samples. Although initial studies conducted with the Psychopathy Checklist: Youth Version (PCL:YV) indicated reasonable fit for these models in incarcerated male adolescents in the United States and the United Kingdom, only one published study has addressed the factor structure of PCL:YV psychopathy in female adolescents, and no prior studies have addressed it outside of these countries. We used confirmatory factor analysis to investigate the factor structure underlying PCL:YV scores in 314 incarcerated (143 male, 171 female) and 193 in-school (99 male, 94 female) adolescents, ages 14 to 19 years. The 2-factor model provided adequate fit only for incarcerated male adolescents and the 4-factor model was problematic in all samples, but the 3-factor solution provided an adequate model in incarcerated and community male adolescents. None of the models provided consistently acceptable fit among female adolescents. Current findings provide evidence for the robustness of the 3-factor model of psychopathy in incarcerated and community male adolescent samples but raise doubts about the applicability of this model to female adolescents.

    Adolescent depression is a severe mental health problem. Philippines has the highest incidence of depression in South East Asia. Depressed female adolescents habitually seek and retain negative experiences. Aim of this research was to develop and to assess effectiveness of a Taking in the Good Based-Bibliotherapy Intervention Program for female adolescents. As an innovative type of psychotherapy treatment, program aimed to build up their inner strengths by experiencing, enriching and absorbing daily events with a positive attitude and installing them in brain. Program was conducted in two phases: 1. Development of taking in the good based-bibliotherapy intervention. 2. Implementation and assessment of pioneering treatment for alleviating depression and thereby increasing positive cognitive appraisal by employing true experimental research design particularly between subjects. Beck Depression Inventory-II, Asian Adolescent Depression Scale and Kutcher Adolescent Depression Scale-11 were administered before and after implementation of the program. A total of 30 female adolescents, Filipino High School students, (mean age=13.9), were randomly assigned to experimental (n=15) and control (n=15) conditions. Data analysis was done by employing percentage and frequency distribution, mean scores, standard deviation, dependent t-test, independent t-test statistics and Cohen's d. The null hypothesis was tested at the 0.05 level of significance. Statistical analysis between the pre-test and post-test scores of the experimental group showed significant difference (p=0.000) and scores of control and experimental group showed significant difference (p=0.000) in all dependent variables in the post-test. These results revealed that "Taking in the Good based-Bibliotherapy Intervention" was effective in reducing depression in female adolescents.

    In spite of the advances in knowledge on the multi-factorial nature of obesity, many questions related to the consequences of the disease continue to be unanswered. Several studies have reported biomechanic and kinematic adaptation and alterations in walking and in tasks of every day life, motivated by the additional load of fat mass in children and adults. The main objective of this study was to understand the effect of obesity in the electromyographic activity of four lower extremity muscles during three speeds of walking and during a countermovement jump (CMJ) in twenty two (9 obese and 13 normal weight) female adolescents aged 13. Although electromyographic differences were not observed between groups for normal, slow and fast speeds, data suggests that the preferred pace of the obese is less efficient than that of the normal weight group. In CMJ task, differences in the after-fall jump phase were observed. More studies are needed to explain if the few differences observed between groups are caused by the bigger amount of fat mass.

    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.

    The relationship between sexual sensation seeking and sexual risk taking has been investigated among adult populations. There are limited data, however, regarding this relationship for adolescents. Since African-American adolescent females continue to be disproportionately diagnosed with STDs, including HIV, we examined this association among a clinic-based sample of African-American adolescent females (N=715) enrolled in an STD/HIV prevention intervention. Participants (ages 15-21) endorsing higher levels of sexual sensation seeking reported higher levels of sexual risk-taking behaviours (e.g. frequency of vaginal intercourse, number of sexual partners, and poorer condom use). Results remained significant after controlling for known covariates associated with sexual risk-taking behaviours. Results are consistent with the adult literature and highlight the need for future investigations examining sexual sensation seeking among adolescents. These results, though preliminary, could be used to better inform prevention interventions and clinicians/health educators who provide direct services to adolescents.

    2016-01-01

    Female adolescent oncology patients undergo many physical changes throughout treatment that have challenging psychological, emotional, and social implications. Body image for this population is a subject that tends to be overlooked in the midst of the cancer experience. This article will examine the complex concept of body image and discuss why female adolescent patients are at such high risk for negative body image. Assessment and care strategies are needed to foster a positive body image, resiliency, and overall well-being. Although survivorship studies may offer insightful information about the effects of the cancer journey on long-term body image, focus should be on prevention and holistic care as part of the treatment itself. The health care team, especially nursing professionals, should acknowledge, recognize, and address this vital issue as a critical part of oncology care.

    2011-08-01

    Age-specific behavioral and neural characteristics may predispose adolescents to initiate and escalate use of alcohol and drugs. Adolescents may avidly seek novel experiences, including drugs of abuse, because of enhanced incentive motivation for drugs and natural rewards, perhaps especially when that incentive motivation is sensitized by prior drug exposure. Using a Pavlovian conditioned approach (PCA) procedure, sign-tracking (ST) and goal-tracking (GT) behavior was examined in amphetamine-sensitized and control adolescent and adult female Sprague-Dawley rats, with expression of elevated ST behavior used to index enhanced incentive motivation for reward-associated cues. Rats were first exposed to a sensitizing regimen of amphetamine injections (3.0 mg/kg/ml d-amphetamine per day) or given saline (0.9% wt/vol) once daily for 4 days. Expression of ST and GT was then examined over 8 days of PCA training consisting of 25 pairings of an 8-s presentation of an illuminated lever immediately followed by response-independent delivery of a banana-flavored food pellet. Results showed that adults clearly displayed more ST behavior than adolescents, reflected via both more contacts with, and shorter latencies to approach, the lever. Prior amphetamine sensitization increased ST (but not GT) behaviors regardless of age. Thus, when indexed via ST, incentive motivation was found to be greater in adults than adolescents, with a prior history of amphetamine exposure generally sensitizing incentive motivation for cues predicting a food reward regardless of age.

  13. Views of adolescent female youth on physical activity during early adolescence.

    2012-01-01

    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.

    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.

    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

    Adolescence is a period of substantial neuroplasticity in stress regulatory neurocircuits. Chronic stress exposure during this period leads to long-lasting changes in neuroendocrine function and emotional behaviors, suggesting adolescence may be a critical period for development of stress vulnerability. This study investigated the effects of exposure to 14 days of chronic variable stress (CVS) in late-adolescent (pnd 45–58) female rats on neuroendocrine function, neuropeptide mRNA expression and depressive-like behavior in adolescence (pnd 59) and in adulthood (pnd 101). Adult females exposed to CVS in adolescence have a blunted hypothalamo-pituitary-adrenocortical (HPA) axis in response to a novel stressor and increased immobility in the forced swim test. Blunted HPA axis responses were accompanied by reduced vasopressin mRNA expression in the paraventricular nucleus of the hypothalamus (PVN), suggesting decreased central drive. Adolescent females tested immediately after CVS did not exhibit differences in stress reactivity or immobility in the forced swim test, despite evidence for enhanced central HPA axis drive (increased CRH mRNA expression in PVN). Overall, our study demonstrates that exposure to chronic stress in adolescence is sufficient to induce lasting changes in neuroendocrine drive and behavior, potentially altering the developmental trajectory of stress circuits as female rats age into adulthood.

    The objective of the current study was to characterize the association between dating violence victimization and dispositional aggression in predicting nonsuicidal self-injury (NSSI) among psychiatrically hospitalized male and female adolescents. One hundred fifty-five adolescents (ages 13-17) and their parents completed the Schedule for Affective Disorders and Schizophrenia for School-Age Children clinical interview to assess NSSI and child abuse; adolescents completed self-report measures of aggression and dating violence victimization (verbal, physical, and sexual). Dating violence victimization and NSSI were found to be highly prevalent among both males and females in this psychiatric inpatient sample. Two moderational models were supported, wherein dating violence was associated with NSSI in the context of elevated trait anger in males and indirect aggression in females. Findings suggest that helping victims of dating violence acquire skills to address certain forms of dispositional aggression may attenuate NSSI.

    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

  2. Review: magnetic resonance imaging of male/female differences in human adolescent brain anatomy

    2012-01-01

    Improvements in neuroimaging technologies, and greater access to their use, have generated a plethora of data regarding male/female differences in the developing brain. Examination of these differences may shed light on the pathophysiology of the many illnesses that differ between the sexes and ultimately lead to more effective interventions. In this review, we attempt to synthesize the anatomic magnetic resonance imaging (MRI) literature of male/female brain differences with emphasis on studies encompassing adolescence – a time of divergence in physical and behavioral characteristics. Across all ages total brain size is consistently reported to be about 10% larger in males. Structures commonly reported to be different between sexes include the caudate nucleus, amygdala, hippocampus, and cerebellum – all noted to have a relatively high density of sex steroid receptors. The direction and magnitude of reported brain differences depends on the methodology of data acquisition and analysis, whether and how the subcomponents are adjusted for the total brain volume difference, and the age of the participants in the studies. Longitudinal studies indicate regional cortical gray matter volumes follow inverted U shaped developmental trajectories with peak size occurring one to three years earlier in females. Cortical gray matter differences are modulated by androgen receptor genotyope and by circulating levels of hormones. White matter volumes increase throughout childhood and adolescence in both sexes but more rapidly in adolescent males resulting in an expanding magnitude of sex differences from childhood to adulthood.

    Aim: 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. Methods: 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. Results: 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. Conclusions: 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. PMID:20121706

    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.

    The adolescent female athlete has become a common part of the sports environment at all levels from childhood play to professional adult sports. This article considers various issues common to this athlete to help clinicians care for their patients. Basic sports physiology is reviewed and then specific conditions are considered, including iron deficiency anemia, stress urinary incontinence, breast issues (ie, pain, asymmetry, galactorrhea, injury), the female athlete triad (ie, menstrual dysfunction, abnormal eating patterns, and osteopenia or osteoporosis), and injuries. Clinical conundrums are considered including the difficulty in caring for a dedicated athlete whose intense love of her sport may lead to menstrual and bone loss complications. The knowledgeable clinician in the twenty-first century can be of considerable help to the female athlete who is at and beyond puberty.

    Background This paper describes the nature and characteristics of the dating relationships of adolescent females, including any of their experiences of abuse. Methods A grounded theory approach was used with 22 theoretically sampled female adolescents ages 15–18. Results 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. Conclusion 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.

    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.

    Compared to adults, adolescents are at heightened risk for drug abuse and dependence. One of the factors contributing to this vulnerability may be age-dependent differences in reward processing, with adolescents approaching reward through stimulus-directed, rather than goal-directed, processes. However, the empirical evidence for this in rodent models of adolescence, particularly those that investigate both sexes, is limited. To address this, male and female rats that were adolescents (P30) or adults (P98) at the start of the experiment were trained in a Pavlovian approach (PA) task and were subsequently tested for the effects of reward devaluation, extinction, and re-acquisition. We found significant interactions between age and sex: females had enhanced acquisition of PA and poorer extinction, relative to males, while adolescents and females were less sensitive to reward devaluation than male adults. These results suggest that females and adolescents exhibit reward behavior that is more stimulus-directed, rather than goal-directed. PMID:23754712

    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.

    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.

    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

    Osteochondroma or osteocartolaginous exostosis is by far the most common benign bone tumour, which accounts for 35% to 50% of benign bone neoplasms and 10% to 15% of all primary bone tumours. Osteochondroma represents a developmental enchondromatous hyperplasia which leads to formation of cartilage capped bony protrusions on bony surfaces. We present a case report of a 14-year- old female, who presented to us with a hard, gradually progressing, large painless swelling, over the left side of her neck. Swelling was nontender, extending from dorsal to ventral aspect, measuring 6 x 8 cm. Therefore, we are interested in introducing our case to medical fraternity, in which a giant lower cervical spine osteochondroma was seen in an adolescent female patient. PMID:24995199

    Marathon runners are ranked in 5-year age groups. However the extent to which 5-year groupings facilitates equitable competition has not been evaluated. The aim of this study was to evaluate the effect of relative age in male and female marathon running. Marathon finishing times for the top ten male (aged 20-69 years) and female athletes (aged 20-64 years) were obtained from the 2013 New York and Chicago marathons. Intra-class and inter-class validity were evaluated by comparing performances within (intra-class) and between (inter-class) the 5-year age groups. Results showed intra-class effects in all male age groups over 50 years, in all female age groups over 40 years, and in male and female 20-24 age groups (p < 0.05). Inter-class differences existed between the 20-24 and 25-29 age groups in both males and females, between all male age groups over 50 years, and between all female age groups over 40 years (p < 0.05). This study provided the first evaluation of the effects of relative age in male and female marathon running. The results provide preliminary but compelling evidence that the relatively older male athletes in age groups over 50 years and the relatively older females in age groups over 40 years are competitively disadvantaged compared to the younger athletes in these age groups. Key points Results showed a curvilinear relationship between age and marathon running performance with the negative effect of age becoming more pronounced in older runners. Relative age effects were found in all age groups over age 50 years in males and over age 40 years in females indicating that the relatively older runners were competitively disadvantaged compared to the relatively younger runners in these age groups. Relative age affected the 20-24 age classification which is consistent with the hypothesis that marathon performance improves until peak performance occurs in the 25-29 age classification.

    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). 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

    This study aims to examine the associations between BMI, disordered eating attitude, body dissatisfaction in female adolescents, and descriptive attributes assigned to silhouettes of varying sizes in male and female adolescents, aged 11 to 15, in rural South Africa. Height and weight were measured to determine BMI. Age and sex-specific cut-offs for underweight and overweight/obesity were determined using the International Obesity Task Force cut-offs. Body image satisfaction using Feel-Ideal Discrepancy (FID) scores, Eating Attitudes Test-26 (EAT-26), and perceptual female silhouettes were collected through self-administered questionnaires in 385 adolescents from the Agincourt Health and Socio-Demographic Surveillance System (HSDSS). Participants self-reported their Tanner pubertal stage and were classified as early pubertal (< = Tanner stage 2), and mid to post pubertal (Tanner stage > 2). Mid to post pubertal boys and girls were significantly heavier, taller, and had higher BMI values than their early pubertal counterparts (all p<0.001). The prevalence of overweight and obesity was higher in the girls than the boys in both pubertal stages. The majority (83.5%) of the girls demonstrated body dissatisfaction (a desire to be thinner or fatter). The girls who wanted to be fatter had a significantly higher BMI than the girls who wanted to be thinner (p<0.001). There were no differences in EAT-26 scores between pubertal groups, within the same sex, and between boys and girls within the two pubertal groups. The majority of the boys and the girls in both pubertal groups perceived the underweight silhouettes to be “unhappy” and “weak” and the majority of girls in both pubertal groups perceived the normal silhouettes to be the “best”. These findings suggest a need for policy intervention that will address a healthy body size among South African adolescents. PMID:27171420

    Fertility and sexuality are important aspects in the quality of life of long-term survivors of cancer. Adolescents in particular are in a very vulnerable period of their lives with respect to future fertility and sexuality. Special attention should be paid to preserve their fertility whenever possible. The gonadotoxic effect of chemotherapy is largely drug- and dosedependent and is related to age. The effect of radiotherapy is also dependent on dose and age and on the radiation therapy field. The prepubertal ovary is the least susceptible to gonadotoxicity. Ablative regimens for stem cell transplantation have an extremely high risk of ovarian failure. Alternative chemotherapy protocols can reduce long-term gonadotoxicity. Alkylating agents impose the highest risk in causing ovarian failure and should be avoided whenever possible. Up to now, the results of gonadoprotective hormonal therapy have been disappointing and contradictory. Transposition of the ovaries should be considered in each case of planned pelvic or whole body irradiation, where ovarian involvement is unlikely and chemotherapy not necessary. Cryopreservation of preimplantation embryos will seldom be possible in female adolescents due to the lack of a stable relationship with a male partner. Cryopreservation of mature and immature oocytes (necessitating in vitro maturation) is still assumed not to be safe for the offspring. Cryopreservation and transplantation of ovarian tissue seems to be the most promising way of future fertility preservation in female adolescents. At present, it is in its early experimental stage. Its safety and possibilities for fertility preservation in humans are not proven as yet. Additionally, technical and ethical issues need to be addressed. The counseling of female adolescents who are facing the threat of cancer needs careful consideration with regards to the psychosocial impact of the treatment and its consequences. Special attention should be paid to aspects of future

  1. Age-varying associations between nonmarital sexual behavior and depressive symptoms across adolescence and young adulthood.

    Research has demonstrated associations between adolescent sexual behavior and depressive symptoms, but no single study has examined individuals at different ages throughout adolescence and young adulthood in order to determine at what ages sexual behavior may be associated with higher or lower levels of depressive symptoms. Using nationally representative longitudinal data and an innovative method, the time-varying effect model (TVEM), which examines how the strength of an association changes over time, this study examines how nonmarital sexual intercourse is associated with depressive symptoms at different ages, which behaviors and contexts may contribute to these associations, and whether associations differ for male and female participants. Findings indicate that sexual behavior in adolescence is associated with a higher level of depressive symptoms, particularly for female adolescents, and this association is relatively consistent across different partner types and adolescent contexts. Associations between sexual behavior and depressive symptoms in young adulthood are more dependent on partner factors and adolescent contexts; sexual behavior in young adulthood is associated with fewer depressive symptoms for women who have sex with a single partner and for men whose parents did not strongly disapprove of adolescent sexual behavior. Findings suggest that delaying sexual behavior into young adulthood may have some benefits for mental health, although contextual and relationship factors also play a role. (PsycINFO Database Record

    This phenomenological study was undertaken to explore in depth the experiences of registered nurses caring for adolescent anorexic females within paediatric wards of general hospitals in Victoria, Australia. A qualitative design underpinned by the philosophy of Edmund Husserl was employed for this study. Audio taped in-depth interviews with five registered nurses working within the public health care system were conducted. Using Colaizzi's procedural steps of analysis, six themes of meaning were explicated. They were: (a) personal core values of nurses; (b) core values challenged; (c) emotional turmoil; (d) frustration; (e) turning points; and (f) resolution. These themes, when taken together, described the essence of the journey undertaken by registered nurses who cared for adolescent anorexic females. The findings of this study indicated that there is a need for extensive registered nurse preparation, on-going support, and development of education programmes to enable registered nurses to care for these patients with greater understanding. Further, the participants identified the need for new care regimes and protocols to be developed that incorporated new ways of thinking. They also expressed a desire to be have greater involvement in the planned care of their patients.

    We explored the role that sexual and social partners play in the expression of female homosexual behavior among adolescent female Japanese macaques at Arashiyama, Japan. Our data fully or partially supported all the predictions related to four non-mutually exclusive hypotheses, namely the "adult male disinterest in adolescent females" hypothesis, the "numerous homosexual adult females" hypothesis, the "safer homosexual interactions" hypothesis and the "same-sex sexual interactions" hypothesis. Our results show that both sexual context (e.g., lack of adolescent female attractivity toward adult males, presence of motivated same-sex sexual partners), and social context (e.g., risk of aggression) help explain the high frequency and prevalence of homosexual behavior in adolescent females in the Arashiyama group of Japanese macaques. As with adult females, whose homosexual consortships do not reflect generalized patterns of social affiliation or kinship, we found that adolescent females' same-sex sexual partners were neither kin, nor were they non-kin individuals with whom adolescent females were closely affiliated outside of a consortship context. Our study furthers the growing database of female homosexual behavior in Japanese macaques and provides additional evidence that homosexual behavior as expressed by adolescent female Japanese macaques is, like heterosexual behavior, sexual in nature. We discuss the relevance of our findings to a broader comparative approach that may shed light upon the development and evolution of human homosexuality.

    The objective of this study is to characterize voice intensity and stability of fundamental frequency, formants and diadochokinesis, vocal modulations, rhythms, and speed of speech in adolescents during follicular and luteal phases of the menstrual cycle. Twenty-three adolescent females who were nonusers of oral contraceptives participated in a cross-sectional study of menstrual cycle influences on voicing and speaking tasks. Acoustic analyses were performed during both phases of the menstrual cycle using the Kay Elemetrics Computer Speech Lab Software Package. Data were analyzed using Student's paired sample t test. Phono-articulatory parameters were similar in both phases of the menstrual cycle (fundamental frequency: 192.6+/-23.9 Hz; minimum formant 891.7+/-110.3 Hz; and maximum formant: 2471.5+/-203.6 Hz). In diadochokinesis, they had a speed of 5.6+/-0.6 seg/s and vocal intensity was 61.5+/-2.6 dB. The mean values for the variations in voice modulations were as follows: anger (21.7+/-8.7 Hz)adolescents showed similar voice fundamental frequency and intensity, formants, speed of speech, and suprasegmental speech parameters. The results shown in this study may be used as standard of acoustic phono-articulatory for adolescents.

    Social interactions in rodents are rewarding and motivating and social isolation is aversive. Accumulating evidence suggests that disruption of the social environment in adolescence has long-term effects on social interactions, on anxiety-like behavior and on stress reactivity. In previous work we showed that adolescent isolation produced increased reactivity to acute and to repeated stress in female rats, whereas lower corticosterone responses to acute stress and decreased anxiety-related behavior were noted in isolated males. These results indicate a sex specific impact on the effects of social stress in adolescence. However, little is known about whether social isolation impacts behaviors related to affect and whether it does so differently in male and female rats. The present study investigated the impact of adolescent social isolation from day 30-50 of age in male and female Sprague Dawley rats on behavior in the forced swim test at the end of adolescence and in adulthood and on behavior in the sucrose preference test in adulthood. Adult female rats that were isolated in adolescence exhibited increased climbing on the first and second day of the forced swim test and showed an increased preference for sucrose compared to adult females that were group-housed in adolescence. There were no effects in male rats. The results indicate that social isolation in adolescence produces a stable and active behavioral phenotype in adult female rats. PMID:21907226

    Early detection of the female athlete triad is essential for the long-term health of adolescent female athletes. The purpose of this study was to assess relationships between common anthropometric markers (ideal body weight [IBW] via the Hamwi formula, youth-percentile body mass index [BMI], adult BMI categories, and body fat percentage [BF%]) and triad components, (low energy availability [EA], measured by dietary restraint [DR], menstrual dysfunction [MD], low bone mineral density [BMD]). In the sample (n = 320) of adolescent female athletes (age 15.9± 1.2 y), Spearman's rho correlations and multiple logistic regression analyses evaluated associations between anthropometric clinical cutoffs and triad components. All underweight categories for the anthropometric measures predicted greater likelihood of MD and low BMD. Athletes with an IBW >85% were nearly 4 times more likely to report MD (OR = 3.7, 95% CI [1.8, 7.9]) and had low BMD (OR = 4.1, 95% CI [1.2, 14.2]). Those in <5th percentile for their age-specific BMI were 9 times more likely to report MD (OR 9.1, 95% CI [1.8, 46.9]) and had low BMD than those in the 50th to 85th percentile. Athletes with a high BF% were almost 3 times more likely to report DR (OR = 2.8, 95% CI [1.4, 6.1]). Our study indicates that low age-adjusted BMI and low IBW may serve as evidence-based clinical indicators that may be practically evaluated in the field, predicting MD and low BMD in adolescents. These measures should be tested for their ability as tools to minimize the risk for the triad.

    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.

    The rationale for our study was to determine the pattern of ethanol drinking by the high alcohol-drinking (HAD) replicate lines of rats during adolescence and adulthood in both male and female rats. Rats were given 30 days of 24 h free-choice access to ethanol (15%, v/v) and water, with ad lib access to food, starting at the beginning of adolescence (PND 30) or adulthood (PND 90). Water and alcohol drinking patterns were monitored 22 h/day with a "lickometer" set-up. The results indicated that adolescent HAD-1 and HAD-2 males consumed the greatest levels of ethanol and had the most well defined ethanol licking binges among the age and sex groups with increasing levels of ethanol consumption throughout adolescence. In addition, following the first week of adolescence, male and female HAD-1 and HAD-2 rats differed in both ethanol consumption levels and ethanol licking behavior. Adult HAD-1 male and female rats did not differ from one another and their ethanol intake or licking behaviors did not change significantly over weeks. Adult HAD-2 male rats maintained a relatively constant level of ethanol consumption across weeks, whereas adult HAD-2 female rats increased ethanol consumption levels over weeks, peaking during the third week when they consumed more than their adult male counterparts. The results indicate that the HAD rat lines could be used as an effective animal model to examine the development of ethanol consumption and binge drinking in adolescent male and female rats providing information on the long-range consequences of adolescent alcohol drinking.

    In this study we explored the role of personal, familial, and cultural attitudes and social norms for physical activity (PA) on actual PA behavior among female adolescents of the Indian diaspora. Six girls, 15 to 19 years of age, from a spiritual center participated in interviews and a focus group. Data were analyzed using content analysis. Participants were high in familism, and felt that PA was important for physical and mental health, and to strengthen relationships with family. Fathers and brothers were considered most influential on PA patterns. Differentiated gender roles in PA emerged: boys were deemed more aggressive and competitive, and girls were perceived to promote fun-based learning environments. The importance of religion and spirituality as influences on PA emerged among participants with strong affinities for Indian cultures. Results show that cultural heritage impacts PA norms, attitudes, and patterns, and must be considered when evaluating adolescent PA participation in multicultural societies.

    Purpose The reproductive health needs of unmarried adolescents in Bangladesh are largely unmet. This study aimed to explore treatment-seeking behaviour of unmarried female adolescents for selected reproductive health (RH) concerns in two low-performing areas of Bangladesh. Methods As part of a large community based-project, a cross-sectional survey was conducted from November 2006 to March 2007. From each of two select study areas, 800 unmarried female adolescents aged 12–19 years were selected for participation by simple random sampling through household listing and were recruited into the study. Trained interviewers administered a structured questionnaire to participating female adolescents. Descriptive and bivariate analytic methods were used compare RH conditions and healthcare seeking behaviour of adolescents across urban and rural settings. Results Approximately 50% of the sample reported experiencing menstrual problems in the last year. The predominant problems reported by participants included: lower abdominal pain, back pain, irregular menstruation, and excessive bleeding during menstruation. Irrespective of study area, only 40% of the female adolescents with menstrual problems sought treatment from qualified physicians. Otherwise, utilization of healthcare facilities and care providers for reported problems varied significantly by rural and urban areas. Higher proportions of adolescents in the urban setting (15%) also reported recent symptoms of sexually transmitted infections (STIs), compared to those in the rural setting (9%; p < 0.001). Across sites, however, self-treatment was the most commonly reported method of care for those who experienced any symptoms of STI. Conclusions In general, treatment-seeking behaviours by unmarried female adolescents was low for menstrual problems. A vast majority of unmarried female adolescents practiced self-care for symptoms of STIs while only small proportions sought treatment from qualified physicians. These

    Sex disparities in dental caries have been observed across many populations, with females typically exhibiting higher prevalence and more affected teeth. In this study we assessed the sex disparities in two Northern Appalachian populations from West Virginia (WV, N = 1997) and Pennsylvania (PA, N = 1080) by comparing caries indices between males and females across four phases of dental development: primary dentition in children aged 1–5 years, mixed dentition in children aged 6–11 years, permanent dentition in adolescents aged 12–17 years, and permanent dentition in adults aged 18–59 years. No significant sex differences were observed for children aged 1–5 years. Contrary to national and international trends, WV girls aged 6–11 years had 1.5 fewer affected teeth than boys (p < 0.001). However, by ages 12–17, caries indices in the WV girls matched those in boys. In both WV and PA adults, women and men had similar total counts of affected teeth (i.e., DMFT), although women had more dental restorations (p < 0.001) and men had more current decay (p < 0.001). These results suggest that in some Appalachian populations, young girls benefit from protection against caries that is lost during adolescence and that adult women utilize dental health care to a greater degree than men.

    Physical activity in adolescence is associated with several health benefits, including a direct influence on adolescent morbidity and an indirect effect on adult health mediated by physical activity levels in adulthood. This study assessed the prevalence of sedentary lifestyle and associated variables in 4,452 adolescents aged 10-12 years, belonging to the 1993 Pelotas Birth Cohort Study, representing 87.5% of the original cohort. Sedentary lifestyle, defined as < 300 minutes per week of physical activity, was reported by 58.2% (95%CI: 56.7-59.7) of the cohort. In the multivariate analysis, sedentary lifestyle was positively associated with female gender, socioeconomic status, maternal physical inactivity, and television viewing, but inversely correlated with time spent playing videogames. Adolescents with low socioeconomic status were more likely to walk or bicycle to and from school. Effective strategies against sedentary lifestyle in adolescence are needed because of its high prevalence and association with physical inactivity in adulthood.

    2014-01-01

    Background Anxiety disorders are associated with adverse psychosocial functioning, and are predictive of a wide range of psychiatric disorders in adulthood. Objective The present study examined the associations between anxiety disorders during childhood and adolescence and psychosocial outcomes at age 30, and sought to address the extent to which psychopathology after age 19 mediated these relations. Method Eight hundred and sixteen participants from a large community sample were interviewed twice during adolescence, at age 24, and at age 30. They completed self-report measures of psychosocial functioning and semi-structured diagnostic interviews during adolescence and young adulthood. Results Childhood anxiety only predicted less years of completed education at age 30, whereas adolescent anxiety predicted income, unemployment, maladjustment, poor coping skills, more chronic stress and life events. Adult major depressive disorder (MDD) was the only disorder predicted by childhood anxiety, whereas adolescent anxiety predicted MDD, substance (SUD) and alcohol abuse/dependence (AUD) in adulthood. No adult psychopathology mediated the relationship between childhood anxiety disorders and psychosocial outcomes at age 30. Adult MDD, SUD and AUD partially or completely mediated the association between adolescent anxiety and most domains of psychosocial functioning at age 30. Limitations The participants are ethically and geographically homogenous, and changes in the diagnostic criteria and the interview schedules across the assessment periods. Conclusion Adolescent anxiety, compared to childhood anxiety, is associated with more adverse psychosocial outcomes at age 30. Adolescent anxiety affects negative outcomes at age 30 directly and through MDD, SUD and AUD. PMID:24456837

    Little data exist for upper and lower body mechanical power capability of adolescent athletes. This study compared arm (A) and leg (L) anaerobic peak and mean power (PP and MP) of 20 male and 20 female adolescent athletes after normalization for body mass (BM), fat-free mass (FFM), and lean A and L cross-sectional area (CSA). Power outputs were assessed by the Wingate anaerobic test. FFM and CSA were estimated via anthropometry. No significant (P > 0.05) differences existed between the sexes in Tanner sexual maturity, chronological age, or overall training activity. Males had higher (P < 0.001) absolute PP (W) (L 694 vs 442; A 494 vs 309) and MP (L 548 vs 307; A 337 vs 214). Ratio normalization and ANCOVA were used to remove the influence of body size differences. Ratio normalization showed that males had greater leg PP/BM, MP/BM, MP/FFM, MP/CSA, as well as arm PP/BM and MP/BM, whereas all leg and arm PP and MP ANCOVA adjusted means for BM, FFM, and CSA, except arm MP adjusted for FFM, were significantly (P < 0.01) higher for males than females. We conclude that factors other than muscle mass, possibly qualitative in nature, are responsible for the sex difference in anaerobic performance of adolescent athletes.

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.

    The study aimed to examine the role of dissociation (persistent versus peritraumatic) in self-injurious behavior among at-risk Israeli female adolescents. In addition, the relationship between childhood sexual abuse, depression, dissociation, and potency was investigated. A convenience sample of 93 female adolescents aged 12 years to 18 years were recruited from institutions for at-risk adolescent girls in Israel. Participants were administered an anonymous self-report questionnaire that included six measures: Demographics, Dissociative Experiences Scale, Center for Epidemiologic Studies Depression Scale, the Peritraumatic Dissociative Experiences Questionnaire, the Traumatic Events Questionnaire, and the Potency Scale. Results indicated that childhood sexual abuse increases the risk for self-injurious behavior more than threefold. Higher levels of persistent dissociation were found among girls who reported child sexual abuse compared to those who did not. Self-injurious behavior was predicted by persistent dissociation. Girls who engaged in self-injurious behavior had lower potency and higher depression levels, regardless of childhood sexual abuse history.

    A longitudinal study examined the emotional and interpersonal processes involved in contraceptive behavior among 201 sexually active female adolescents 14-19 years of age recruited from adolescent medicine clinics in San Francisco, California (US). At study entry, adolescents completed questionnaires regarding sociodemographics, sexual and reproductive history, sexual self-acceptance, sexual communication with partners, and current contraceptive use. At a 6-month follow-up interview, participants reported on all sexual activity and contraceptive use since study enrollment. Path analysis indicated greater sexual self-acceptance was significantly related to more sexual communication and more contraceptive communication. Contraceptive communication, in turn, was associated with more frequent and more effective contraceptive use. Higher levels of contraceptive communication predicted both more frequent and more effective contraceptive use at the 6-month follow-up even when the effects of baseline contraceptive use were controlled. When the association between sexual self-acceptance and subsequent contraceptive behavior was examined apart from communication about sexuality and contraception, sexual self-acceptance directly predicted contraceptive effectiveness but not frequency. These findings underscore the importance of interpersonal processes in sexual and contraceptive behavior and suggest the utility of interventions that provide adolescents with skills for discussing contraception.

    A 16-year-old girl presented with primary amenorrhea and had had cyclical abdominal pain for almost a year. At examination we observed a painful mass in the lower abdomen and normal secondary sex characteristics. Perineal examination showed a bluish bulging hymen. Transabdominal ultrasonography revealed a dense mass in the pelvis measuring about 12×11 cm. We diagnosed an imperforate hymen with haematocolpos and haematometra. The hymen was opened surgically and a large quantity of menstrual blood was drained from the vagina and uterus. Postoperative recovery was normal without any pain. The patient now menstruates regularly. An imperforate hymen occurs in 0.05% of women. It is important to be aware of this while examining a female adolescent presenting with cyclical abdominal pain and primary amenorrhea. Late discovery of an imperforate hymen may lead to pain, infections, hydronephrosis and endometriosis with subfertility as a possible consequence. PMID:21686660

  11. Acute exertional anterior compartment syndrome in an adolescent female.

    Acute compartment syndromes usually occur as a complication of major trauma. While the chronic exertional anterior tibial compartment syndrome is well described in the sports medicine literature, reports of acute tibial compartment syndromes due to physical exertion, or repetitive microtrauma, are rare. The case of an adolescent female who developed an acute anterior compartment syndrome from running in a soccer game is described in this report. Failure to recognize the onset of an acute exertional compartment syndrome may lead to treatment delay and serious complications. Whereas the chronic exertional anterior compartment syndrome is characterized by pain that diminishes with the cessation of exercise, the onset of the acute exertional anterior compartment syndrome is heralded by pain that continues, or increases, after exercise has stopped. Compartment pressure measurement confirms the clinical diagnosis and helps guide treatment. True compartment syndromes require urgent fasciotomy.

    Age at first sexual intercourse (AFSI) is the initial factor related to adolescents' sexual life that may increase the risk of adolescent pregnancy. We explored the biological, social, cultural, and political predictors of AFSI addressing several gaps that prevent us from generalizing the results of past research to adolescent pregnancy prevention. We also explored the moderating effects of cultural variables on the links between social and political predictors and AFSI. Our sample consisted of 889 Portuguese female adolescents aged 12-19. Earlier age at menarche, non-intact family structure, maternal history of adolescent pregnancy, lower maternal emotional warmth, absence of religious involvement, and living in Portugal's mainland and in a legal context penalizing abortion predicted earlier AFSI. School attendance predicted earlier AFSI among adolescents of European ethnic origin; adolescents of non-European ethnic origin presented the opposite, but non-significant, pattern. These findings suggest that, in addition to isolated characteristics, factors from different ecological contexts should be considered when planning interventions designed to foster healthy and informed transitions to sexual initiation and prevent the related risks of unwanted outcomes. We discuss implications for future research and practice.

    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.

    Aim The aim of this study was to evaluate the use of the London Atlas of Human Tooth Development and Eruption for age estimation in Saudi Arabian children and adolescents (aged 2–20 years), for forensic odontology application. Materials and methods This cross-sectional survey analyzed orthopantomograms (OPGs) of the complete dentition (including root development) to estimate the deviation from chronological age. Each OPG was de-identified and analyzed individually and classified into age-groups by the lead author, using the methods of the Atlas of Tooth Development. Results OPGs from a total of 252 patients [110 (44%) males, 142 (56%) females] aged 2–20 years (24–240 months) were examined in this study. The average estimated and chronological ages of subjects differed significantly p < 0.001 (143 ± 55.4 vs. 145 ± 57.9 months). Most (65.5%) estimates were within 12 months of subjects’ chronological ages; 19% overestimated and 15.5% underestimated age by >12 months. Conclusion This study, conducted in a sub-population of different origin than the UK sample used for the development of the London Atlas, identified variation in age estimates that may have significant impacts on results. The establishment of a composite international repository of atlas-based data for diverse ethnic sub-populations would be of great value to clinicians across the globe. PMID:26236126

    Purpose: There is lack of evidence on the effects of health-promoting programmes among adolescents. Health behaviour models and studies seldom compare the underlying factors of unhealthy behaviours between different adolescent age groups. The main objective of this study was to investigate factors including sociodemographic parameters that were associated with vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours in different adolescent age groups. Methods: A survey was conducted among 10,590 pupils in the age groups of 13–14, 15–16 and 17–18 years. Structural equation modelling was performed to determine whether health-damaging behaviours (smoking and alcohol consumption) and non-adoption of health-enhancing behaviours (regular meal habits and physical activity) shared an underlying vulnerability. This method was also used to determine whether gender and socio-economic status were associated with an underlying vulnerability to unhealthy behaviours. Results: The findings gave rise to three models, which may reflect the underlying vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours at different ages during adolescence. The four behaviours shared what was interpreted as an underlying vulnerability in the 15–16-year-old age group. In the youngest group, all behaviours except for non-participation in physical activity shared an underlying vulnerability. Similarly, alcohol consumption did not form part of the underlying vulnerability in the oldest group. Lower socio-economic status was associated with an underlying vulnerability in all the age groups; female gender was associated with vulnerability in the youngest adolescents and male gender among the oldest adolescents. Conclusions: These results suggest that intervention studies should investigate the benefits of health-promoting programmes designed to prevent health-damaging behaviours and promote health-enhancing behaviours in

    Some youths develop multiple substance use disorders early in adolescence and have severe, persistent courses. Such youths often exhibit impulsivity, risk-taking, and problems of inhibition. However, relatively little is known about the possible brain bases of these behavioral traits, especially among females. Methods We recruited right-handed female patients, 14–19 years of age, from a university-based treatment program for youths with substance use disorders and community controls similar for age, race and zip code of residence. We obtained 43 T1-weighted structural brain images (22 patients and 21 controls) to examine group differences in cortical thickness across the entire brain as well as six a priori regions-of-interest: 1) medial orbitofrontal cortex; 2) rostral anterior cingulate cortex; and 3) middle frontal cortex, in each hemisphere. Age and IQ were entered as nuisance factors for all analyses. Results A priori region-of-interest analyses yielded no significant differences. However, whole-brain group comparisons revealed that the left pregenual rostral anterior cingulate cortex extending into the left medial orbitofrontal region (355.84 mm2 in size), a subset of two of our a priori regions-of-interest, was significantly thinner in patients compared to controls (vertex-level threshold p = 0.005 and cluster-level family wise error corrected threshold p = 0.05). The whole-brain group differences did not survive after adjusting for depression or externalizing scores. Whole-brain within-patient analyses demonstrated a positive association between cortical thickness in the left precuneus and behavioral disinhibition scores (458.23 mm2 in size). Conclusions Adolescent females with substance use disorders have significant differences in brain cortical thickness in regions engaged by the default mode network and that have been associated with problems of emotional dysregulation, inhibition, and behavioral control in past studies.

    The aim of this study was to estimate the level of knowledge about sexuality, attitudes and sexual behaviour of female adolescents. The study included 194 female students, 117 from Medical High School (MHS) and 77 from General High School (GHS) in Zagreb. Data was collected using an anonymous self-administered questionnaire. In addition to items on personal data (age, parental education etc.), the participants were asked to define terms about sexuality (e.g. menstruation, puberty) the definitions of which are found in biology textbooks for the fifth and eighth grade of primary school. The aim of the third part of the survey was to collect information about attitudes and behaviour of female adolescents. The results showed a low level of knowledge in students of both schools. General High School students showed a higher level of knowledge than their Medical High School peers. One fifth of General High School students and 1/3 of Medical High School students were unable to define the term "menstruation". The majority of adolescents talk about sexuality with their friends, 92.1% of General High School and 81.2% of Medical High School students. Almost 50% of students of both schools would like to talk about sexuality with their school doctor. 6.9% of Medical High School students had at least one sexual intercourse while none of the General High School students had been sexually active at the time of the survey. As the majority of students were not sexually active and results showed a rather low level of knowledge, this seems to be the ideal period for the implementation of educational programs aimed at increasing the level of knowledge, and thus preventing unwanted consequences (STD, pregnancy, abortion, infertility).

    Purpose Child sexual abuse and sexual dating violence victimization are common problems that are known to have long-term negative consequences. This study aimed to compare the sociodemographic, abuse-related, and clinical features of female adolescents who were sexually abused by different perpetrators, and identify the factors associated with suicidality and nonsuicidal self-injury (NSSI) in these cases. Patients and methods Data of 254 sexually abused female adolescents between the ages of 12–18 years were evaluated. The cases were classified into three groups, namely “sexual dating violence”, “incest”, and “other child sexual abuse”, according to the identity of the perpetrator. The three groups were compared in terms of sociodemographic, abuse-related, and clinical features. Results Major depressive disorder was the most common psychiatric diagnosis, which was present in 44.9% of the cases. Among all victims, 25.6% had attempted suicide, 52.0% had suicidal ideation, and 23.6% had NSSI during the postabuse period. A logistic regression analysis revealed that attempted suicide was predicted by dating violence victimization (adjusted odds ratio [AOR] =3.053; 95% confidence interval [CI] =1.473, 6.330) and depression (AOR =2.238; 95% CI =1.226, 4.086). Dating violence victimization was also the strongest predictor of subsequent suicidal ideation (AOR =3.500; 95% CI =1.817, 6.741). In addition, revictimization was determined to be an important risk factor for both suicidal ideation (AOR =2.897; 95% CI =1.276, 6.574) and NSSI (AOR =3.847; 95% CI =1.899, 7.794). Conclusion Perpetrator identity and revictimization are associated with negative mental health outcomes in sexually victimized female adolescents. Increased risk of suicidality and NSSI should be borne in mind while assessing cases with dating violence and revictimization histories, in particular. PMID:27382291

    Background 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. Aims To empirically assess the links between media use, indoor tanning-related outcome expectations, and behavioral intentions. Method 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. Results 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. Discussion 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. Conclusion These findings highlight the social nature of adolescent females and point to specific intervention channels for reducing indoor tanning among this population.

    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.

    Traditional pregnancy prevention strategies employed with adults and older teens do not recognize significant developmental differences between early adolescents and other age groups. Methods that compliment, reflect, and are consistent with developmental needs of the young teen provide cogent approaches to teen pregnancy prevention. Particular emphasis should be placed on interpersonal relationships and their importance in the young woman's life, especially the relationship between the young teen and her parents. Developing and improving all relationships instrumental in positively affecting teen decision-making represent potent approaches to pregnancy prevention. The axioms of Piaget, Erikson, and Mercer are examined in regard to cognitive, social, emotional, and psychosexual development in the 12-14 year old. Young teens' responses to sex education as well as their use of contraception are reviewed in relation to developmental theory.

    While cognitive and emotional systems both undergo development during adolescence, few studies have explored top-down inhibitory control brain activity in the context of affective processing, critical to informing adolescent psychopathology. In this study, we used functional magnetic resonance imaging to examine brain response during an Emotional Conflict (EmC) Task across 10-15-year-old youth. During the EmC Task, participants indicated the emotion of facial expressions, while disregarding emotion-congruent and incongruent words printed across the faces. We examined the relationships of age, sex, and gonadal hormones with brain activity on Incongruent vs. Congruent trials. Age was negatively associated with middle frontal gyrus activity, controlling for performance and movement confounds. Sex differences were present in occipital and parietal cortices, and were driven by activation in females, and deactivation in males to Congruent trials. Testosterone was negatively related with frontal and striatal brain response in males, and cerebellar and precuneus response in females. Estradiol was negatively related with fronto-cerebellar, cingulate, and precuneus brain activity in males, and positively related with occipital response in females. To our knowledge, this is the first study reporting the effects of age, sex, and sex steroids during an emotion-cognition task in adolescents. Further research is needed to examine longitudinal development of emotion-cognition interactions and deviations in psychiatric disorders in adolescence.

    The southeastern US sustains the highest high school dropout rates, and gangs persist in underserved communities. African American female adolescents who drop out of school and are gang members are at substantial risk of exposure to severe violence, physical abuse, and sexual exploitation. In this study of 237 female African American adolescents 16-19 years of age from North Carolina who dropped out or considered dropping out, 11% were current or past gang members. Adolescents who reported gang membership began smoking marijuana at a mean age of 13, whereas those who reported no gang membership began at a mean age of 15 years (P<0.001). The mean ages of first alcohol use were 14 years and 15 years for gang members and non-gang members, respectively (P=0.04). Problem alcohol use was high in both groups: 40% and 65% for non-gang and gang members, respectively (P=0.02). Controlling for frequent marijuana use and problem alcohol use, adolescents who reported gang membership were more likely than non-gang members to experience sexual abuse (odds ratio [OR] =2.60, 95% confidence interval [CI] [1.06, 6.40]), experience physical abuse (OR =7.33, 95% CI [2.90, 18.5]), report emotional abuse from their main partner (OR =3.55, 95% CI [1.44, 8.72]), run away from home (OR =4.65, 95% CI [1.90, 11.4]), get arrested (OR =2.61, 95% CI [1.05, 6.47]), and report violence in their neighborhood including murder (OR =3.27, 95% CI [1.35, 7.96]) and fights with weapons (OR =3.06, 95% CI [1.15, 8.11]). Gang members were less likely to receive emotional support (OR =0.89, 95% CI [0.81, 0.97]). These findings reinforce the urgent need to reach young African American women in disadvantaged communities affiliated with gangs to address the complexity of context and interconnected risk behaviors.

    We previously reported that males undergoing chronic social stress (SS) (daily 1h isolation and new cage partner on days 30-45 of age) in adolescence habituated (decreased corticosterone release) to the homotypic stressor, but females did not. Here, we report that adolescent males exposed to chronic social stress had potentiated corticosterone release to a heterotypic stressor (15 min of swim stress) compared to acutely stressed and control males. The three groups of males did not differ in depressive-like behaviour (time spent immobile) during the swim stress. Corticosterone release in socially stressed females was elevated 45 min after the swim stress compared to acutely stressed and control females, and socially stressed females exhibited more depressive behaviour (longer durations of immobility and shorter durations of climbing) than the other females during the swim stress. Separate groups of rats were tested as adults several weeks after the social stress, and there were no group differences in corticosterone release after the swim stress. The only group difference in behaviour among the adults was more time spent climbing in socially stressed males than in controls. Thus, there are sex-specific effects of social stress in adolescence on endocrine responses and depressive behaviour to a heterotypic stressor, but, unlike for anxiety, substantial recovery is evident in adulthood in the absence of intervening stress exposures.

Sixteen adolescent soccer players were studied (age 13.4 ± 0.5 years) across 14 weeks. The control group (general soccer training only) had 6 subjects, and the plyometric training (general soccer training plus plyometric exercise) group had 10 subjects. All subjects were tested for VJ and kicking distance on 3 occasions: pre-test, 7 weeks, and 14 weeks. Data were analyzed using a 2 (Training) × 3 (Test) analysis of variance (ANOVA) with repeated measures on the factor test. No significant difference in kicking distance was found between groups at pre-test (p = 0.688) or 7 weeks (p = 0.117). The plyometric group had significantly greater kicking distance after 14 weeks (p < 0.001). No significant difference in VJ height was found between groups at pre-test (p = 0.837) or 7 weeks (p = 0.108). The plyometric group had a significantly higher VJ after 14 weeks (p = 0.014). These results provide strength coaches with a safe and effective alternative to high-intensity plyometric training. Based on these findings, to increase lower-body power resulting in increased VJ and kicking distance, strength coaches should implement once-weekly, low-impact plyometric training programs with their adolescent athletes.

    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.

    Few childhood studies have investigated racial differences in volumetric bone mineral density (vBMD), bone geometry, and bone strength indices measured by three-dimensional bone imaging. The purpose of this study was to compare trabecular and cortical bone parameters at the radius and tibia between late adolescent white and black females using peripheral quantitative computed tomography (QCT). White (n = 25) and black females (n = 25), 18-19 years of age, were pair-matched for age, height, and fat-free soft tissue mass. Peripheral QCT scans were obtained at the 4% (trabecular bone), 20% (cortical bone), and 66% [muscle cross-sectional area (CSA)] sites from the distal metaphyses. Bone strength was determined from vBMD and bone geometry to calculate bone strength index (BSI; trabecular site) and polar strength-strain index (SSI; cortical site). Radial SSI was not different between groups; however, blacks had greater radial BSI (P = 0.02) than whites. After adjustment for the longer forearm in blacks, the greater radial BSI in blacks no longer remained. At the tibia, blacks versus whites had greater bone strength at the trabecular and cortical bone sites (BSI, P = 0.03; SSI, P = 0.04, respectively). When controlling for differences in tibial length and muscle CSA, the higher estimates of bone strength persisted in blacks versus whites (BSI, P = 0.01; SSI, P = 0.02). Our data suggest that when differences in body size are considered, late adolescent black versus white females have a stronger bone profile, due to greater bone geometry and vBMD, at the trabecular and cortical regions of the tibia but not at the radius.

    Thyroid autoimmune disease, a widespread phenomenon in female population, impairs thyroid function during pregnancy. Identifying cases, which will develop hypothyroidism during pregnancy, is crucial in the follow-up process. The study group comprised 108 females, with ages between 20-40 years; with known inactive autoimmune thyroid disease, before pregnancy that became pregnant in the study follow-up period. They were monitored by means of clinical, hormonal and immunological assays. Supplemental therapy with thyroid hormones was used, where needed. Maternal age and level of anti-thyroid antibodies were used to predict thyroid functional impairment.

    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.

    This is the first study to explore whether mandated reporters who work with adolescent females, ages 10 to 17, recognize domestic minor sex trafficking (DMST) and associated risk factors. Because mandated reporters are required by law to report child abuse, neglect, and child exploitation, lack of specific DMST training or not believing DMST exists in communities continues to place young females at risk for revictimization. Results indicate that 60% of mandated reporters in the sample (N = 577) had no specific training on DMST. Furthermore, almost 25% of respondents did not believe DMST existed in their communities. Implications for practice are discussed. (PsycINFO Database Record

    Objective To test the feasibility of a randomized-controlled trial measuring the impact of an adapted mindfulness-based intervention (MBI) in female adolescents with chronic pain. Methods This was a single center, single-blind, prospective, experimental, longitudinal trial conducted in a pediatric tertiary care center. Participants had a history of chronic pain during at least three months. They were randomized into an intervention group or a wait-list control group. Both groups successively followed an adapted eight-week MBI designed specifically for adolescents with chronic pain. Pre-determined criteria were established to assess the feasibility, validity and acceptability of the study model. Data evaluating changes in quality of life, depression, anxiety, pain perception, psychological distress and salivary cortisol were collected throughout the 4-month study period. Results Nineteen female participants completed the study and had a mean age of 15.8 years (range 13.9 -17.8). Attrition rate was low (17%). Attendance to mindfulness sessions (84%) and compliance to study protocol (100%) were high. All participants reported a positive change in the way they coped with pain. No changes in quality of life, depression, anxiety, pain perception, and psychological distress were detected. Significant reductions in pre-and post-mindfulness session salivary cortisol levels were observed (p<0.001). Conclusions Mindfulness is a promising therapeutic approach for which limited data exist in adolescents with chronic pain. Our study indicates the feasibility of conducting such interventions in teenage girls. A large trial is needed to demonstrate the efficacy and bio-physiological impacts of MBIs in teenagers with chronic pain. PMID:27924146

    2016-02-01

    We examined how genotype-environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother-adolescent and father-adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and nonpassive genotype-environment correlation based on biometric moderation findings. The findings indicated that nonpassive gene-environment correlation played a stronger role for positivity in mother- and father-adolescent relationships in families with older adolescents than in families with younger adolescents, and that passive gene-environment correlation played a stronger role for positivity in the mother-adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed.

    BACKGROUND AND OBJECTIVE: Most clinic-based weight control treatments for youth have been designed for preadolescent children by using family-based care. However, as adolescents become more autonomous and less motivated by parental influence, this strategy may be less appropriate. This study evaluated a primary care–based, multicomponent lifestyle intervention specifically tailored for overweight adolescent females. METHODS: Adolescent girls (N = 208) 12 to 17 years of age (mean ± SD: 14.1 ± 1.4 years), with a mean ± SD BMI percentile of 97.09 ± 2.27, were assigned randomly to the intervention or usual care control group. The gender and developmentally tailored intervention included a focus on adoptable healthy lifestyle behaviors and was reinforced by ongoing feedback from the teen’s primary care physician. Of those randomized, 195 (94%) completed the 6-month posttreatment assessment, and 173 (83%) completed the 12-month follow-up. The primary outcome was reduction in BMI z score. RESULTS: The decrease in BMI z score over time was significantly greater for intervention participants compared with usual care participants (−0.15 in BMI z score among intervention participants compared with −0.08 among usual care participants; P = .012). The 2 groups did not differ in secondary metabolic or psychosocial outcomes. Compared with usual care, intervention participants reported less reduction in frequency of family meals and less fast-food intake. CONCLUSIONS: A 5-month, medium-intensity, primary care–based, multicomponent behavioral intervention was associated with significant and sustained decreases in BMI z scores among obese adolescent girls compared with those receiving usual care.

    2017-01-01

    Evaluation of the female reproductive system in a general toxicity setting can be challenging for the toxicologic pathologist due to the cyclic nature of the estrous and menstrual cycles, timing of puberty and reproductive senescence, and species differences. Age in particular can have a significant impact on the histologic appearance of the female reproductive system and create challenges when trying to distinguish test article-related findings from normal developmental or senescent changes. This review describes the key physiologic and histologic features of immaturity, the transition through puberty, sexual maturity, and reproductive senescence in the female reproductive system, with an emphasis on practical applications for the toxicologic pathologist, and includes recommendations for distinguishing and documenting these developmental periods. Rats and cynomolgus monkeys are used as examples throughout with correlations to clinically observed end points to better aid the toxicologic pathologist in understanding how age may impact study interpretation.

    The purpose of this study was to assess differences in the levels of plasma visfatin among female adolescents and changes in plasma visfatin and insulin resistance in obese female adolescents after 12 wk of aerobic exercise training. Twenty normal-weight female students (body-mass index [BMI] < 22.9 kg/m² and body fat ≤ 29.9) and 18 obese female students (BMI ≥ 25 kg/ m² and body fat ≥ 30%) participated in this study. Eleven obese students were assigned to an exercise group and completed a 12-wk aerobic exercise-training program that included four 40- to 50-min sessions per wk with an energy expenditure of 300-400 kcal/d. Seven obese students were assigned to a control group that received no exercise sessions or dietary restriction. The plasma visfatin levels of obese female adolescents were significantly higher (p < .05) than those of the normal-weight female adolescents. The plasma visfatin levels (294.00 ± 124.74 ng/ml to 185.55 ± 67.30 ng/ml, p < .01) and insulin resistance (p < .05) were significantly reduced after 12 wk of aerobic exercise. The results suggest that aerobic exercise resulting in an energy expenditure of 1,200-1,600 kcal/wk for 12 wk decreases plasma visfatin and insulin resistance in obese female adolescents.

    Purpose To examine whether perceived peer/parent norms or personal beliefs about adolescent substance use influence substance use among female adolescents with chronic medical conditions. Methods 68 females reported on substance use, personal beliefs, and perceived peer/parent norms. Results Personal beliefs and perceived peer/parent norms were associated with adolescent’s current and future substance use. Although perceived peer norms accounted for variance in current substance use, only personal beliefs accounted for variance in future alcohol use. Conclusions Targeting perceived peer norms may be effective for intervention efforts among adolescents endorsing current substance use, whereas alcohol use prevention efforts should target personal beliefs.

    Macromastia in adolescents is multifactorial and usually idiopathic, associated with obesity or hormonal imbalances. Less commonly, it can result from virginal or juvenile breast hypertrophy, a rare condition of unknown etiology, where an alarmingly rapid breast enlargement occurs during puberty. Breast hypertrophy in the adolescent population can have significant long-term medical and psychological impacts. Although symptoms can be severe, many plastic surgeons, pediatricians, and parents are often reluctant to surgically treat adolescent macromastia. However, reduction mammoplasty is a safe and effective treatment and may be the only way to alleviate the increased social, psychological, and physical strain caused by macromastia in adolescents.

    Background. The State of Kuwait has a growing obesity epidemic in both genders and all age groups; however, obesity rates in the young seem to be rising. Methods. 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.

    Behavioural mimicry is a potential mechanism explaining why adolescents appear to be influenced by their parents' eating behaviour. In the current study we examined whether there is evidence that adolescent females mimic their parents when eating. Videos of thirty-eight parent and female adolescent dyads eating a lunchtime meal together were examined. We tested whether a parent placing a food item into their mouth was associated with an increased likelihood that their adolescent child would place any food item (non-specific mimicry) or the same item (specific mimicry) in their mouth at three different time frames, namely, during the same second or within the next fifteen seconds (+15), five seconds (+5) or two second (+2) period. Parents and adolescents' overall food intake was positively correlated, whereby a parent eating a larger amount of food was associated with the adolescent eating a larger meal. Across all of the three time frames adolescents were more likely to place a food item in their mouth if their parent had recently placed that same food item in their mouth (specific food item mimicry); however, there was no evidence of non-specific mimicry. This observational study suggests that when eating in a social context there is evidence that adolescent females may mimic their parental eating behaviour, selecting and eating more of a food item if their parent has just started to eat that food.

  18. Lifetime Number of Mates Interacts with Female Age to Determine Reproductive Success in Female Guppies

    PubMed Central

    Evans, Jonathan P.

    2012-01-01

    In many species, mating with multiple males confers benefits to females, but these benefits may be offset by the direct and indirect costs associated with elevated mating frequency. Although mating frequency (number of mating events) is often positively associated with the degree of multiple mating (actual number of males mated), most studies have experimentally separated these effects when exploring their implications for female fitness. In this paper I describe an alternative approach using the guppy Poecilia reticulata, a livebearing freshwater fish in which females benefit directly and indirectly from mating with multiple males via consensual matings but incur direct and indirect costs of mating as a consequence of male sexual harassment. In the present study, females were experimentally assigned different numbers of mates throughout their lives in order to explore how elevated mating frequency and multiple mating combine to influence lifetime reproductive success (LRS) and survival (i.e. direct components of female fitness). Under this mating design, survival and LRS were not significantly affected by mating treatment, but there was a significant interaction between brood size and reproductive cycle (a correlate of female age) because females assigned to the high mating treatment produced significantly fewer offspring later in life compared to their low-mating counterparts. This negative effect of mating treatment later in life may be important in these relatively long-lived fishes, and this effect may be further exacerbated by the known cross-generational fitness costs of sexual harassment in guppies.

    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

    The present study aimed to examine differences in psychosocial and developmental characteristics between Adolescent Females who have committed Sexual Offenses (AFSOs; n = 40), Adolescent Females who have committed nonsexual Violent Offenses (AFVOs; n = 533), and Adolescent Males who have committed Sexual Offenses (AMSO, n = 743). Results showed that AFSOs and AMSOs were remarkably similar, whereas AFSOs and AFVOs were remarkably different on the measured variables. Compared to AFVOs, AFSOs less often had antisocial friends and problems in the domains of school (truancy, behavior problems, dropping out of school) and family (e.g., parental problems, poor authority and control, and run away from home). Victimization of sexual abuse outside the family and social isolation were found to be more common in AFSOs than in AFVOs. Victimization of sexual abuse outside the family was the only specific characteristic of female adolescent sexual offending, as this was more common in AFSOs than in both AMSOs and AFVOs.

    Objective Previous research has yielded evidence of increased attentional processing of negatively valenced body parts in women with anorexia nervosa (AN), especially for those with high depressive symptomatology. The present study extended previous research by implementing an experimental mood manipulation. Method In a within-subjects design, female adolescents with AN (n = 12) and an age matched female control group (CG; n = 12) were given a negative and a positive mood induction at a one-week interval. After each mood induction, participants underwent a 3-min mirror exposure, while their eye movements were recorded. Results After the positive mood induction, both AN and CG participants displayed longer and more frequent gazes towards their self-defined most ugly relative to their self-defined most beautiful body part. However, after the negative mood induction, only females with AN were characterized by increased attention to their most ugly compared to their most beautiful body part, while CG participants’ attention distribution was balanced. Furthermore, in the negative (but not in the positive) mood induction condition gaze frequency and duration towards the most ugly body part was significantly stronger in the AN group relative to the CG. Discussion The results emphasize the role of negative mood in the maintenance of pathological information processing of the self-body. This increased body-related negativity-bias during negative mood may lead to the persistence and aggravation of AN patients’ body image disturbance. PMID:27123587

    Background: Exposure to environmental phenols (e.g., bisphenol A, benzophenone-3, and triclosan) and parabens is widespread in the population. Many of these chemicals have been shown to have anti-androgenic effects both in vitro and in vivo. Objective: We examined the association of bisphenol A (BPA), benzophenone-3 (BP-3), triclosan (TCS), and parabens with serum total testosterone (TT) levels in child and adolescent participants (ages 6–19 years) in the National Health and Nutrition Examination Survey (NHANES) 2011–2012. Methods: We performed multivariable linear regression to estimate associations between natural log–transformed serum TT and quartiles of urinary BPA, BP-3, TCS, and parabens in male and female children (ages 6–11 years) and adolescents (ages 12–19 years). Results: BP-3 and BPA were associated with significantly lower TT in male adolescents, and BPA was associated with significantly higher TT in female adolescents. TT was not consistently associated with TCS or total parabens in children or adolescents of either sex. Conclusions: To our knowledge, this is the first study to report an association of both BP-3 and BPA with serum TT in adolescents. Associations between BPA and TT differed according to sex in adolescents, with inverse associations in boys and positive associations in girls. BP-3 was associated with significantly lower TT in adolescent boys only. However, because of the limitations inherent to the cross-sectional study design, further studies are needed to confirm and elucidate on our findings. Citation: Scinicariello F, Buser MC. 2016.

    The literature on relative age position effects is rather inconsistent. In this study we examined intra-classroom age position (or relative age) effects on Dutch adolescents’ school progress and performance (as rated by teachers), physical development, temperamental development (fear and frustration), and depressive symptoms, all adjusted for age at the time of measurement. Data were derived from three waves of Tracking Adolescents' Individuals Lives Survey (TRAILS) of 2230 Dutch adolescents (baseline mean age 11.1, SD = 0.6, 51% girls). Albeit relative age predicted school progress (grade retention ORs = 0.83 for each month, skipped grade OR = 1.47, both p<.001), our key observation is the absence of substantial developmental differences as a result of relative age position in Dutch adolescents with a normative school trajectory, in contrast to most literature. For adolescents who had repeated a grade inverse relative age effects were observed, in terms of physical development and school performance, as well as on depressive symptoms, favoring the relatively young. Cross-cultural differences in relative age effect may be partly explained by the decision threshold for grade retention. PMID:26076384

    Background Genital secretions collected from adult women exhibit in vitro activity against herpes simplex virus (HSV) and Escherichia coli (E. coli), but prior studies have not investigated this endogenous antimicrobial activity or its mediators in adolescent females. Methodology/Principal Findings Anti-HSV and anti-E.coli activity were quantified from cervicovaginal lavage (CVL) specimens collected from 20 sexually active adolescent females (15–18 years). Soluble immune mediators that may influence this activity were measured in CVL, and concentrations of Lactobacillus jensenii and crispatus were quantified by PCR from vaginal swabs. Results for adolescents were compared to those obtained from 54 healthy, premenopausal adult women. Relative to specimens collected from adults, CVL collected from adolescent subjects had significantly reduced activity against E. coli and diminished concentrations of protein, IgG, and IgA but significantly increased anti-HSV activity and concentrations of interleukin (IL)-1α, IL-6 and IL-1 receptor antagonist. Vaginal swabs collected from adolescent subjects had comparable concentrations of L. crispatus but significantly reduced concentrations of L. jensenii, relative to adult swabs. Conclusions/Significance Biomarkers of genital mucosal innate immunity may differ substantially between sexually active adolescents and adult women. These findings warrant further study and may have significant implications for prevention of sexually transmitted infections in adolescent females. PMID:22808157

  13. The role of the brain in female reproductive aging.

    In middle-aged women, follicular depletion is a critical factor mediating the menopausal transition; however, all levels of the hypothalamic-pituitary-gonadal (HPG) axis contribute to the age-related decline in reproductive function. To help elucidate the complex interactions between the ovary and brain during middle-age that lead to the onset of the menopause, we utilize animal models which share striking similarities in reproductive physiology. Our results show that during middle-age, prior to any overt irregularities in estrous cyclicity, the ability of 17beta-estradiol (E(2)) to modulate the cascade of neurochemical events required for preovulatory gonadotropin-releasing hormone (GnRH) release and a luteinizing hormone (LH) surge is diminished. Middle-aged female rats experience a delay in and an attenuation of LH release in response to E(2). Additionally, although we do not observe a decrease in GnRH neuron number until a very advanced age, E(2)-mediated GnRH neuronal activation declines during the earliest stages of age-related reproductive decline. Numerous hypothalamic neuropeptides and neurochemical stimulatory inputs (i.e., glutamate, norepinephrine (NE), and vasoactive intestinal peptide (VIP)) that drive the E(2)-mediated GnRH/LH surge appear to dampen with age or lack the precise temporal coordination required for a specific pattern of GnRH secretion, while inhibitory signals such as gamma-aminobutyric acid (GABA) and opioid peptides remain unchanged or elevated during the afternoon of proestrus. These changes, occurring at the level of the hypothalamus, lead to irregular estrous cycles and, ultimately, the cessation of reproductive function. Taken together, our studies indicate that the hypothalamus is an important contributor to age-related female reproductive decline.

    In Japan, where the society is fast aging at an unprecedented pace, osteoporosis is estimated to affect more than 15 million individuals, thus representing a "common" disease, which exactly meets the definition of a lifestyle-related disease. As osteoporosis has a predominantly female prevalence and bone accounts for the most marked gender difference all organs commonly affected in males and females alike, to have an understanding of the development and aging of bone in women represents an urgent task toward gaining a better understanding of the pathophysiology of osteoporosis affecting them as well as its clinical stages. In this context, the benefit of ensuring bone health has been identified as maintenance of ADL/QOL in the elderly as well as prevention of osteoporotic fractures which lead to affected individuals becoming bed-ridden and requiring nursing care.

    Selection can favour the evolution of a high reproductive rate early in life even when this results in a subsequent increase in the rate of mortality, because selection is relatively weak late in life. However, the optimal reproductive schedule of a female may be suboptimal to any one of her mates, and males may thus be selected to modulate female reproductive rate. Owing to such sexual conflict, coevolution between males and females may contribute to the evolution of senescence. By using replicated beetle populations selected for reproduction at an early or late age, we show that males evolve to affect senescence in females in a manner consistent with the genetic interests of males. 'Late' males evolved to decelerate senescence and increase the lifespan of control females, relative to 'early' males. Our findings demonstrate that adaptive evolution in one sex may involve its effects on senescence in the other, showing that the evolution of optimal life histories in one sex may be either facilitated or constrained by genes expressed in the other.

    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.

    Although quantifiable assessment of the singing voice is now commonplace, research on young (child and adolescent) voices is still in its infancy. There is still insufficient data on young people's voices based on which, "norms" in behavior could be modeled, particularly for contemporary commercial music (CCM), such as musical theater (MT). The objective of this study was to assess if quantifiable differences in vocal production and acoustic output of young singers exist between "classical" and "MT" styles. The study was a prospective cohort study of 20 adolescent female singers aged 12-17 years training their voices using a system, which includes both "classical" and "MT" styles. The study examined laryngographically derived closed quotient (CQ), average vowel spectra (AVS) and long-term average spectra (LTAS) measures of the sung voices of singers in "classical" and "MT" styles. The spectral slope was shallower for the MT voice, and the mean CQ was significantly higher across the pitch range when singing in an MT style than in a "classical" style. The second to fifth harmonics were stronger in the MT style than in classical, with a significant difference between the two styles. The increase in relative intensity in the first five harmonics was disproportionately higher than the increase in CQ. Results, therefore, suggested that MT singing primarily uses change in resonance strategy rather than raised vocal tension to achieve the tonal changes associated with the genre.

    African Americans make up the greater proportion of AIDS cases in adolescent girls but little is understood about the development of sexual risk behaviors during the early adolescent years. This article will explore ecological factors influencing adolescent sexual risk behaviors. In the focus groups, which were conducted using 28 African American mothers and their early adolescent daughters, 2 major themes emerged: exposure and support systems. Mothers described the impact community had on their daughters and how monitoring and support systems worked together to control exposure. The girls detailed the different ways they were impacted by the community. Attitudes the girls adopted from their exposures resulted in risk-taking behaviors or a determination to positively impact the community. Community was shown to be the context of the acquisition of sexual knowledge and attitudes. These findings support the development of interventions to address the impact of community on the participation of sexual risk behaviors.

    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.

    Gray matter loss in cortical regions is a normal ageing process for the healthy brain. There have been few studies on the process of ageing of the brain in chronic neurological disorders. In this study, we evaluated changes in the cortical thickness by age in 92 female subjects (46 migraine patients, and 46 healthy controls) using high field MRI. The results indicate that in contrast to healthy subjects migraineurs show lack of thinning in the insula by age. The functional significance of the lack of thinning is unknown, but may contribute to the overall cortical hyperexcitability of the migraine brain since the region is tightly involved in a number of majo brain networks involved in interoception, salience, nociception, and autonomic function, including the default mode network.

    Background: Adolescents who suffer from depression early in life, have an increase in suicidal tendency, anxiety, conduct disorders, substance abuse, and continue to be depressed, later on in life. This study was conducted to identify the prevalence and correlates of depression among adolescent girls in Riyadh city in order to carry out early intervention. Methods: A cross-sectional, school-based survey was conducted among 1028 adolescent girls aged 15–19 years in secondary schools of Riyadh city. Riyadh was divided into clusters and within each cluster, both public and private schools were enrolled. From the selected schools students from grade 10–12 were surveyed. Survey was conducted using a structured questionnaire including the beck depression inventory-II, and questions exploring the correlates of depression. Results: About 30% of participants were found to be depressed. Depression was more prevalent among female adolescents whose household income was <12,000 Saudi Riyal/month (odds ratio [OR] 2.17, confidence interval [CI] 0.97–6.84), did not have a good relationship with peers and family members (OR 4.63, CI 2.56–8.41), lived with single parent or alone (OR 1.77, CI 0.97–3.23), been emotionally abused (OR 3.45, CI 2.56–8.41), and those who had been subjected to physical violence, at least once (OR 3.34, CI 1.89–5.91). Conclusions: Strategies need to be developed to identify early signs and symptoms of depression among Saudi female adolescents. Training can be given to groups of students to help their peers, and also to the teachers to identify, and help students identify early signs of depression and provide them with better-coping strategies to combat progression of depression and anxiety among such adolescents.

    2012-01-01

    Background Elite adolescent female figure skaters compete in an aesthetic-based sport that values thin builds and lithe figures. To conform to the sport’s physical requirements, skaters may alter their eating patterns in unhealthful directions. This study assesses the eating attitudes and dietary intakes of elite adolescent female figure skaters to assess the potential nutritional risks among them. Methods Thirty-six elite competitive adolescent female figure skaters (mean age 16 ± 2.5 SD years) completed self-administered three-day records of dietary intake and simultaneous physical activity records during training season. Two months later, they attended a national training camp during which they completed the Eating Attitudes Test (EAT-40), provided fasting blood samples, and had heights and weights measured. Results Participants’ mean body mass index (BMI) was 19.8 ± 2.1 SD. Their BMIs were within the normal range, and the majority (70%) did not report a history of recent weight loss. The mean EAT-40 score was normal (19.5 ± 13.5 SD) and below the cut-off score of 30 that indicates clinically significant eating pathology. However, one-quarter of the skaters had EAT-40 scores above 30. The skaters reported a mean energy intake of 1491 ± 471 SD kcal/day (31 ± 10 SD kcal/kg), with 61.6% of calories from carbohydrate, 14.6% from protein, and 23.7% from fat. Their reported dietary intakes were high in carbohydrates but low in total energy, fat, and bone-building nutrients. Conclusions Although these highly active young women compete in a sport that prizes leanness, they had appropriate weights. The athletes reported dietary intakes that were far below estimated energy needs and were at moderate risk of disordered eating. Anticipatory guidance is warranted to improve their dietary intakes, particularly of bone-building nutrients. PMID:23237333

  6. The age-crime curve in adolescence and early adulthood is not due to age differences in economic status.

    2013-06-01

    One of the most consistent findings in developmental criminology is the "age-crime curve"-the observation that criminal behavior increases in adolescence and decreases in adulthood. Recently, Brown and Males (Justice policy J 8:1-30, 2011) conducted an analysis of aggregate arrest, poverty, and population data from California and concluded that the widely-observed adolescent peak in rates of offending is not a consequence of developmental factors, but rather an artifact of age differences in economic status. Youngsters, they argue, offend more than adults because they are poorer than adults. The present study challenges Brown and Males' proposition by analyzing data from the National Longitudinal Study of Youth (NLSY97; N = 8,984; 51% female; 26% Black, 21% Hispanic, 52% non-Black, non-Hispanic; ages 12-18 at Wave 1), which collected measures of criminal behavior and economic status at multiple time points. Consistent with scores of other studies, we find that criminal offending peaks in adolescence, even after controlling for variation in economic status. Our findings both counter Brown and Males' claim that the age-crime curve is illusory and underscore the danger of drawing inferences about individual behavior from analysis of aggregated data.

    This study of 522 African American female adolescents, ages 14 to 18, investigated associations between condom use and infrequently communicating with sex partners about sexually transmitted diseases (STDs) and pregnancy prevention. Correlates of infrequent communication were identified. Sexually active adolescents were recruited from schools and adolescent medicine clinics in low-income neighborhoods of Birmingham, Alabama. Adolescents completed a self-administered survey and face-to-face interview. Communication frequency was assessed using a five-item scale. Infrequent communication was significantly associated with lower odds of condom use. Multivariate correlates of infrequent communication were less frequent communication with parents about STD/pregnancy prevention, recent sex with a nonsteady partner, low perceived ability to negotiate condom use and fear of this negotiation, and low motivation to use condoms. Given the importance of partner communication in promoting safer sex behaviors, STD and pregnancy prevention programs may benefit adolescents by addressing the identified psychosocial correlates of infrequent communication with their partners.

    The study was performed to evaluate relationships among the major anthropological parameters: (body mass - BM, height, body mass index - BMI, lean body mass - FFM, proportion of fat mass -Fat%), physical capacity, and the tennis federations ranking position as an index of the temporal sport success. Seventeen elite female tennis players, divided into three age-matched groups (15, 16, and 17 yr) participated in this study. All the players had a national singles ranking (positions between 1st-80th) and in International Tennis Federation's Junior Circuit ranking (ITFJC; 21st to 990th position of ITF). Body composition was assessed via bioelectrical impedance. Maximal aerobic capacity (VO2max) was calculated from the distance covered in 12-min run test via Cooper's formula. Wingate test with lactate assay was used as an index of anaerobic capacity. There was a significant age-related trend for an increase in BM, height, FFT, and Fat%, associated with impressive shift of the anthropological indexes of body weight and height, assessed by the percentile chart analysis. The unexpected body growth spurt evidently observed between aged 15 and 17 is supposed to reflect a delay in somatic development, related to extensive exercise load. Body composition did not correlate to the ranking positions. All tested tennis players revealed excellent aerobic capacity associated with poor indices of anaerobic fitness. The position in the tennis federations rankings correlated to VO2max but not with maximal power or maximal work output assessed by Wingate test. In the whole group the maximal power and work output were proportional to BMI and FFM, but not to Fat%. In conclusion, in light of the contradictory reports concerning a possible link between strenuous regular exercise performed by young children and adolescent elite sportsmen our data indicate a delayed growth spurt in the elite female tennis players to occur between ages 15 and 17.

    Gonadal hyperfunction is the most frequent endocrine dysfunction in females with McCune-Albright syndrome (MAS). Peripheral precocious puberty is usually the first MAS manifestation in children, characterized by episodes of hypersecretion of estrogens with a consequent reduction in gonadotropin secretion. Little is known about the course of this endocrine disease in adolescence and during young adult life. The aim of this study was to evaluate ovarian function in 10 females with MAS (age 11.4-20.1 years) to detect the persistence of autonomous ovarian hyperfunction throughout and following adolescence, after at least 1 year wash out of any treatment for precocious puberty. LH, FSH, estradiol, prolactin, androgen secretion, ovarian and breast sonography in luteal and follicular phases of some menstrual cycles were evaluated. We demonstrated the persistence of some ovarian autonomy, documented by hyperestrogenism and/or low or absent gonadotropin secretion and/or ovarian cysts.

    Landing awkwardly from a jump is a common mechanism of injury for the anterior cruciate ligament (ACL) of the knee. Augmented feedback, such as verbal or visual instruction, has been shown to cause an immediate, positive change in landing biomechanics in a laboratory setting. No data exist on the longer term effects of feedback on jump landing biomechanics in a sports-specific setting. The purpose of this study was to explore whether providing video and verbal feedback to adolescent (12-14 years old) female volleyball athletes would improve their landing technique. Trunk and lower extremity kinematic variables were measured in 19 participants before a feedback session was provided to the intervention group (IG). Follow-up kinematic measurements of the IG were taken immediately postintervention, and again after 2 and 4 weeks. Two-way repeated measures analysis of variance (ANOVA) was used to compare the IG with a control group (CG), who received no feedback. The IG (n = 10) demonstrated increased maximal hip and trunk flexion compared with the CG (n = 9) at week 4 (p ≤ 0.05). One-way repeated measures ANOVA was used to determine if changes were evident within the IG over time. Ankle dorsiflexion, right knee and hip flexion, and trunk flexion changed significantly (p ≤ 0.05) over the 4-week period. Augmented feedback appeared to produce a positive change in landing biomechanics in adolescent female volleyball athletes performing a sports-specific skill. Courtside video and verbal feedback may present a relatively simple, cost-effective method of introducing one component of a comprehensive ACL injury prevention program at a young age.

    Despite growing trends in adolescent female aggression, much adolescent aggression research has focused on males to the exclusion of their female counterparts. Using relational-cultural and social role theories, the current study identifies the risk and promotive factors associated with adolescent female aggression. Using data from the Rural Adaptation Project (a 5 year longitudinal panel study of youth from two rural, ethnically diverse, low income counties in North Carolina), a 2-level hierarchical linear model was estimated (N = 3580). Internalizing symptoms, association with delinquent friends, peer pressure, and parent-child conflict emerged as risk factors whereas teacher support was a significant promotive factor. Results suggest that interventions should focus on negative relationships in both the parent and peer domains and underscore the need for mental health services for aggressive girls.

    2012-01-01

    Adolescent health and health literacy are critical health topics recognized in Healthy People 2020. Evidence indicates that adolescents who are d/Deaf have unique health-related needs, yet health communication efforts have not reached them. Despite the Internet's exponential growth and the growth of online health information-seeking behavior among adolescents, reliable information devoted specifically to d/Deaf adolescents who communicate primarily in ASL is rare. D/deaf adolescent females face numerous challenges accessing web-based health information to enhance their decision making about important health issues such as body image, physical activity and nutrition, puberty, and relationships. A strong need exists for interdisciplinary professionals to investigate the health interests and online health information-seeking behaviors of this group in order to effectively plan, implement, and evaluate a web-based health repository that delivers content in ASL. This Call to Action represents a first step in addressing that need.

    2013-04-01

    The aim of this study was to evaluate the metabolic syndrome (MetS) prevalence in adolescents using three different definitions for this age group. The evaluated sample consisted of 718 male and 743 female adolescents. Definitions by Cook et al., de Ferranti et al. and International Diabetes Federation (IDF) for adolescents were used to estimate the prevalence of MetS. The prevalence of MetS was 8.5, 2.5 and 1.2% by de Ferranti et al., Cook et al. and IDF definitions, respectively. High fasting glucose component had the lower prevalence whereas high triglycerides levels component was the most prevalent. In obese adolescents, the prevalence of MetS was higher. MetS classification in adolescents strongly depends on the definition chosen. Further research is required for the evaluation of the current definitions (multicentric studies), and for addition or design of new and useful criteria.

    We compared age-related changes in wrinkles in eight areas of facial skin (forehead, glabella, upper eyelid, corner of the eye, lower eyelid, nasolabial groove, cheek, and corner of the mouth) and sagging in the subzygomatic area of Caucasian females and of Japanese females. The subjects studied included 85 healthy Caucasian females (ages 20-69 years) living in Cincinnati in the U.S. and 70 Japanese females (ages 20-69 years) living in Tokyo. Photos of the face in frontal and in oblique 45 degrees views were analyzed. Wrinkles in the face and sagging in the subzygomatic area were graded on Japanese photoscales, respectively, by the same experienced observer. The wrinkle score increased with age in all eight areas of the face examined in Caucasian females as well as in Japanese females. In the group aged 20-29 years, the wrinkle score in each area was significantly higher in Caucasian females than in Japanese females. The wrinkle scores in the forehead, glabella, upper eyelid, and corner of the eye were similar at advanced ages between the two groups, while the wrinkle scores in lower areas of the face (lower eyelid, nasolabial groove, cheek, and corner of the mouth) were markedly higher in Caucasian females than in Japanese females in each age group, and reached an upper limit at advanced ages in Caucasian females. The sagging score also increased with age in Caucasian females as well as in Japanese females. The sagging score was significantly higher in Caucasian females than in Japanese females in the groups aged 40 years or more. These results suggest more marked wrinkle formation in all areas of the face in younger age groups of Caucasian females living in North America than in Japanese females living in Tokyo. In particular, Caucasian females showed marked age-related wrinkle formation in the lower areas of the face, probably due to sagging in the subzygomatic area, which suggests a higher susceptibility to sagging in the subzygomatic area of Caucasian females.

    The current study tested a developmental-contextual model of depressive symptomatology among Mexican-origin, female early and middle adolescents and their mothers. The final sample comprised 271 dyads. We examined the interrelations among cultural (i.e., acculturation dissonance), developmental (i.e., pubertal development and autonomy expectation discrepancies), and interpersonal (i.e., mother-daughter conflict and maternal supportive parenting) factors in predicting adolescents' depressive symptoms. For both early and middle adolescents, maternal support was negatively associated with mother-daughter conflict and depressive symptoms. Mother-daughter autonomy expectation discrepancies were positively associated with mother-daughter conflict, but this association was found only among early adolescents. Further, mother-daughter acculturation dissonance was positively associated with mother-daughter conflict but only among middle adolescents. Findings call for concurrently examining the interface of developmental, relational, and cultural factors in predicting female adolescents' depressive symptomatology and the potential differences by developmental stage (e.g., early vs. middle adolescence).

  16. Developmentally Sensitive Markers of Personality Functioning in Adolescents: Age-Specific and Age-Neutral Expressions.

    2016-05-23

    Criterion D of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association [APA], 2013) refers to a possible onset of personality disorders (PDs) in adolescence and in Section II the development/course in adolescence is described by some typical characteristics for several PDs. Yet, age-specific expressions of PDs are lacking in Section III. We urgently need a developmentally sensitive assessment instrument that differentiates developmental and contextual changes on the one hand from expressions of personality pathology on the other hand. Therefore we investigated which items of the Severity Indices for Personality Problems-118 (SIPP-118) were developmentally sensitive throughout adolescence and adulthood and which could be considered more age-specific markers requiring other content or thresholds over age groups. Applying item response theory (IRT) we detected differential item functioning (DIF) in 36% of the items in matched samples of 639 adolescents versus 639 adults. The DIF across age groups mainly reflected a different degree of symptom expressions for the same underlying level of functioning. The threshold for exhibiting symptoms given a certain degree of personality dysfunction was lower in adolescence for areas of personality functioning related to the Self and Interpersonal domains. Some items also measured a latent construct of personality functioning differently across adolescents and adults. This suggests that several facets of the SIPP-118 do not solely measure aspects of personality pathology in adolescents, but likely include more developmental issues. (PsycINFO Database Record

    Introduction The objective of this study was to examine age-, hormone-, and sex-dependent differences to the behavioral effects of nicotine using place-conditioning procedures in female rats. Methods Animals received nicotine in their initially non-preferred side and saline on alternate days in their initially preferred side. Following four conditioning trials, rats were retested for their preference. To examine developmental differences, we compared the effects of various nicotine doses in female and male adolescent and adult rats. To examine whether our developmental differences are specific to nicotine, we included adolescent and adult females that were conditioned with various amphetamine doses. To examine the influence of hormones on the behavioral effects of nicotine, we compared the effects of various nicotine doses in intact females that were tested during different phases of the estrous cycle and in separate females that were ovariectomized. Result The rewarding effects of nicotine were observed at a lower nicotine dose in adolescents versus adults. Amphetamine produced similar rewarding effects across age groups in females. The shifts in preference produced by nicotine were similar across the different phases of estrous. Females lacking ovarian hormones did not display rewarding effects of nicotine at any dose. The rewarding effects of nicotine were enhanced in adult female versus male rats. An intermediate nicotine dose produced rewarding effects in adolescent male but not female rats, suggesting that developmental differences to nicotine may be enhanced in males. Conclusion In females, nicotine reward is enhanced during adolescence and is facilitated by the presence of ovarian hormones. PMID:19629450

  20. National and state vaccination coverage among adolescents aged 13-17 years--United States, 2012.

    PubMed

    2013-08-30

    At ages 11 through 12 years, the Advisory Committee on Immunization Practices (ACIP) recommends that preteens receive 1 dose of tetanus, diphtheria, and acellular pertussis (Tdap) vaccine, 1 dose of meningococcal conjugate (MenACWY) vaccine, and 3 doses of human papillomavirus (HPV) vaccine. ACIP recommends administration of all age-appropriate vaccines during a single visit. ACIP also recommends that pre-teens and older adolescents receive an annual influenza vaccine as well as any overdue vaccines (e.g., varicella). To monitor vaccination coverage among persons aged 13-17 years, CDC analyzed data from the National Immunization Survey-Teen (NIS-Teen). This report highlights findings of that analysis. From 2011 to 2012, coverage increased for ≥1 Tdap vaccine dose (from 78.2% to 84.6%), ≥1 MenACWY vaccine dose (from 70.5% to 74.0%) and, among males, ≥1 HPV vaccine dose (from 8.3% to 20.8%). Among females, vaccination coverage estimates for each HPV vaccine series dose were similar in 2012 compared with 2011. Coverage varied substantially among states. Regarding Healthy People 2020 targets for adolescents, 36 states achieved targets for Tdap, 12 for MenACWY, and nine for varicella vaccine coverage. Large and increasing coverage differences between Tdap and other vaccines recommended for adolescents indicate that substantial missed opportunities remain for vaccinating teens, especially against HPV infection. Health-care providers should administer recommended HPV and meningococcal vaccinations to boys and girls during the same visits when Tdap vaccine is given. In addition, whether for health problems or well-checks, providers, parents, and adolescents should use every health-care visit as an opportunity to review adolescents' immunization histories and ensure that every adolescent is fully vaccinated.

  1. 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.

  2. Sex Trafficking Related Knowledge, Awareness, and Attitudes among Adolescent Female Students in Nepal: A Cross-Sectional Study

    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

    BACKGROUND Brazil has witnessed dramatic changes in its fertility patterns in recent decades. The decline to below-replacement fertility has been accompanied by increases in the proportion of children born to young mothers. Yet we know little about the well-being of children born to young mothers in Brazil. OBJECTIVE and METHODS Using data from the 2006 Pesquisa Nacional de Demografia e Saúde and a quasi-natural experimental approach, this study examines the implications of maternal age at first birth for the education of Brazilian adolescents. RESULTS We find that being born to a young mother is associated with educational disadvantages in adolescence, but that these disadvantages are attenuated once we account for mothers’ selection into early childbearing. We also find that, in southern Brazil, adolescents born to young mothers have poorer educational outcomes compared with their peers born to older mothers, but that in northern Brazil no such disparities exist. CONCLUSIONS Adolescent educational disadvantages associated with being born to a young mother are not an artifact of selectivity, at least in southern Brazil. Regional variation in the effect of maternal age at first birth on adolescent education suggests the important role of the extended family and the father’s presence as mechanisms through which disadvantages operate.

    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. The study also indicates that stress may exert differential effects on adolescent ethanol intake as a function of the level of anxiety response.

    Background Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. 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. Methods 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. Results 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'. Screen time was significantly (p < 0.05) correlated inversely with the intake of breakfast, vegetables and fruit. Physical activity had a significant (p < 0.05) positive relationship with fruit and vegetable intake but not with sedentary behaviors.

    PubMed

    Fox, Jeremy K; Halpern, Leslie F; Ryan, Julie L; Lowe, Kelly A

    2010-02-01

    Although the tripartite model reliably distinguishes anxiety and depression in adolescents, it remains unclear how negative affectivity (NA) and positive affectivity (PA) influence developmental pathways to internalizing problems. Based on models which propose that affectivity shapes how youth react to stress, the present study attempted to investigate the relative roles of NA, PA, and stressful life events in characterizing and differentiating adolescent anxiety and depression. A sample of adolescent females (N=63), including a sub-sample of adolescent mothers, completed measures of NA, PA, negative life event (NLE) occurrence, anxiety, and depression. Findings supported the tripartite model as a "temperamental reactivity to stress" approach. Anxious and depressive symptoms were predicted by a combination of high NA and high NLE occurrence. However, a combination of low PA and high NLE occurrence was uniquely linked to greater depressive symptoms. Implications of these findings for early identification and prevention programs are discussed.

    Research to elucidate early alterations of higher cognitive processes in adolescents with BPD is rare. This study investigated differences in dual-task performance in adolescents with BPD during stress and non-stress conditions. The study sample comprised 30 female adolescents with BPD and 34 healthy controls. The impact of stress on dual-task performance was measured using a standardized stressor. Self-reports of distress and measures of heart rate (HR) were obtained to measure stress reactivity. There were no group differences in task performance. Under stress conditions, the performance on the auditory task decreased in both groups but without significant group differences. Healthy controls showed an increase of mean HR after stress induction compared to no change in the BPD group. The finding of attenuated HR response to acute stress in adolescent patients with BPD may contradict current theories that the affective hyperresponsivity in BPD is based on a biologically determined mechanism.

    2011-10-01

    The purpose of the present study was to investigate the coping strategies and self-concept of Korean female early adolescents. These adolescents (n = 351) were enrolled in a middle school in Seoul. The subjects completed the Multidimensional Self-Concept Scale and Coping Responses Inventory questionnaires. The subjects exhibited the greatest positivity with regard to family self-concept and the greatest negativity with regard to academic self-concept. The subjects most frequently used the seeking guidance strategy of approach coping and the seeking alternative rewards strategy of avoidance coping. Self-concept was positively or negatively related with various coping skills. Using content analysis, seven categories including discord in family relationships were identified. The results of this study provide information that will aid school nurses working with adolescents with regard to helping the adolescents develop a positive self-concept and more effective coping strategies.

    Increasing emphasis is being placed on optimizing calcium intake during growth as a way to enhance peak bone mass. Although some studies in adults have shown that high calcium intake may negatively affect magnesium utilization, few data are available regarding the interaction of calcium and magnesium in healthy children. The purpose of our study was to measure the effect of calcium intake on magnesium balance in 26 adolescent girls (mean age 11.3 y) during a 14-d period. Subjects ate a controlled basal diet containing 667 mg Ca and 176 mg Mg. In addition to the basal diet, subjects were randomly assigned in a double-blind fashion to consume 1000 mg elemental Ca/d as calcium citrate malate or a placebo. Magnesium use did not differ between the low-calcium and high-calcium groups as measured by absorption (50% compared with 55%), urinary excretion (70 compared with 74 mg/d), and fecal excretion (88 compared with 79 mg/d). Accordingly, magnesium balance was not different in subjects consuming 667 or 1667 mg Ca/d and averaged 21 mg Mg/d for the whole study group. Magnesium balance was significantly correlated with magnesium intake (r = 0.511, P = 0.008) and magnesium absorption (r = 0.723, P < 0.001). Prediction intervals from the regression of magnesium balance on intake indicated that the current recommended dietary allowance of magnesium would result in magnesium balance > or = 8.5 mg/d in 95% of the girls. This value appears consistent with long-term accretion rates needed to account for the expansion of the total-body magnesium pool during growth. In summary, our observations support the adequacy of the current recommended dietary allowance for magnesium and indicate that alterations in magnesium utilization should not be anticipated in adolescent females consuming a high-calcium diet.

    Bisphenol-A (BPA), a common environmental endocrine disruptor, modulates estrogenic, androgenic, and antiandrogenic effects throughout the lifespan. We recently showed that low dose BPA exposure during adolescence increases anxiety and impairs spatial memory independent of sex. In this study, six week old Sprague Dawley rats (n=24 males, n=24 females) received daily subcutaneous injections (40 µg/kg bodyweight) of BPA or vehicle for one week. Serum corticosterone levels in response to a 1 h restraint stress and spine density were examined at age 7 (cohort 1) and 11 (cohort 2) weeks. Adolescent BPA exposure did not alter stress dependent corticosterone responses but decreased spine density on apical and basal dendrites of pyramidal cells in the medial prefrontal cortex (mPFC) and hippocampal CA1 region (CA1). Sex differences in spine density were observed on basal dendrites of the mPFC and CA1 with females having greater spine density than males. This sex difference was further augmented by both age and treatment, with results indicating that BPA-dependent decreases in spine density were more pronounced in males than females on mPFC basal dendrites. Importantly, the robust neuronal alterations were observed in animals exposed to BPA levels below the current U.S.E.P.A. recommended safe daily limit. These results are the first demonstrating that BPA given during adolescence leads to enduring effects on neural morphology at adulthood. Given that humans are routinely exposed to low levels of BPA through a variety of sources, the decreased spine density reported in both male and female rats after BPA exposure warrants further investigation.

    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.

  15. Along came a spider who sat down beside her: Perceived predation risk, but not female age, affects female mate choosiness.

    Organisms often exhibit behavioral plasticity in response to changes in factors, such as predation risk, mate density, and age. Particularly, female mate choosiness (the strength of female's attraction to male traits as they deviate from preferred trait values) has repeatedly been shown to be plastic. This is due to the costs associated with searching for preferred males fluctuating with changes in such factors. Because these factors can interact naturally, it is important to understand how female mate choosiness responds to these interactions. We studied the interaction between perceived predation risk and female age on the variable field cricket, Gryllus lineaticeps. Females were either exposed or not exposed to predation cues from a sympatric, cursorial, wolf spider predator, Hogna sp. We then tested the females at one of three adult ages and measured their choosiness by recording their responsiveness to a low quality male song. We found female choosiness plasticity was affected by neither age nor the interaction between age and perceived predation risk. Perceived predation risk was the only factor to significantly affect the plasticity of female mate choosiness: females were less choosy when they perceived predation risk and were more choosy when they did not. Predation may be such a strong source of selection that, regardless of differences in other factors, most individuals respond similarly.

    Objectives We investigated the similarities and differences in the factors related to human papillomavirus (HPV) vaccination of female adolescents in three sub-regions of the Intermountain West (IW). Methods We analyzed 2011-2012 National Immunization Survey-Teen data. Respondents (parents) who were living in the IW and who had daughters aged 13-17 years old with provider-verified immunization records were included in our analyses. East, Central, and West sub-regions were defined based on geographic contiguity and similarity in HPV vaccination rates and sociodemographic characteristics. Survey-weighted Chi square tests and multivariable Poisson regressions were performed. Results In all three sub-regions, older teen age and receipt of other recommended adolescent vaccinations were significantly associated with HPV vaccination. In the East sub-region, providers' facility type and source of vaccines were significantly related to HPV vaccination. In the Central sub-region, teens with married parents were significantly less likely to be vaccinated than were those with unmarried parents. In the West sub-region, non-Hispanic teens were significantly less likely to be vaccinated than were Hispanic teens. Conclusions for Practice In order to improve HPV vaccine coverage in the IW, region-wide efforts to target younger teens and to promote the HPV vaccine with other recommended adolescent vaccinations should be supplemented with sub-regional attention to the health care system (East sub-region), to married parents (Central sub-region), and to non-Hispanic teens (West sub-region).

    Research on intimate partner violence (IPV) has evolved over the last decade with increasing interest in how IPV develops over adolescence and young adulthood. Studies examining patterns of IPV over time have generally focused on victimization with less attention to temporal shifts in perpetration. While it is generally assumed that IPV peaks during young adulthood, this has not been empirically verified and documented. Additionally, prior longitudinal analyses of IPV have focused on identifying trajectories and their accompanying risk factors, with less attention given to within-individual change in IPV experiences across and within relationships. Drawing on five waves of data from the Toledo Adolescent Relationships Study (TARS), we examined patterns of the perpetration of IPV among a diverse sample of adolescents and young adults (51.1% female, 63.9% non-Hispanic White, 24.6% non-Hispanic Black, 11.5% Hispanic) spanning the ages of 13–28 years (N = 1,164). Analyses demonstrated that IPV patterns deviate from the age-crime curve, with women’s involvement in IPV increasing, while their involvement in other antisocial behaviors is decreasing. Traditional behavioral and psychological risk factors (delinquency, alcohol and drug use, depressive symptoms) accounted for some of the age variation in IPV for men, but these factors did not account for age variation in IPV among women. Relationship risk factors including frequency of disagreements, trust, jealousy, validation and self-disclosure, however, accounted for substantial portions of the age-IPV perpetration relationship for male and female youth. These findings reinforce recent calls for prevention efforts that focus on the development and maintenance of healthy relationships. PMID:25081024

    A study was conducted to examine how interpersonal norms, media norms, attitudes, perceived behavioral control, perceived barriers, and self-efficacy had an influence on healthy eating intention among adolescents. A probability sample of 544 adolescents aged 12 to 18 was conducted. Results indicated that girls had a more favorable attitude and intention toward healthy eating than boys. Healthy eating intention among boys was predicted by attitude, perceived behavioral control, perceived barriers, and self-efficacy, and among girls was predicted by perceived behavioral control and self-efficacy. Different marketing strategies to promote healthy eating among adolescent boys and girls should be adopted.

    Aims To determine how genetic and environmental contributions affecting the number of psychoactive substances used varies with age and gender over the course of adolescence Design Estimates of genetic, shared environmental, and non-shared environmental contributions to total variance in diversity of substances used at ages 11, 14 , and 17 were obtained by fitting a multivariate behavior genetic (Cholesky) model. Participants 711 male and 675 female twins. Measurements Participants reported whether they had used each of 11 substances. Findings The average diversity of substances used increased over time for both males and females, and males generally reported a wider diversity of substances used than females. Influences of genetic factors increased with age and were greater for males than for females at ages 14 and 17. Genetic factors remained consistent (i.e. highly correlated) across ages for both males and females, as did shared environmental influences for males. Non-shared environmental factors for both sexes and females’ shared environmental factors were age-specific. Conclusions Regardless of sex, the proportion of variance in substances used attributable to genetic factors increases during adolescence, although it is greater for males than females at later ages. These findings indicate that prevention interventions may be most effective if they target early adolescence when environmental factors account for the majority of variance in substance use. The high correlation of genetic factors across ages suggests that early use may sometimes signal an early expression of a developmentally stable genetic predisposition. PMID:18821880

    Pace, Ugo; Cacioppo, Marco; Schimmenti, Adriano

    2012-04-01

    The present study examined the association between quality of attachment, perception of the father's bond, and binge eating symptoms in a sample of female late adolescents. In total, 233 female students aged between 18 and 20 years completed measures on binge eating, quality of attachment and parent-child relationship. Data showed that respondents with binge symptoms reported lower scores on secure attachment and father's care, and higher scores on preoccupied and fearful attachment. Binge eating symptoms were associated with father's care, but not with father's overprotection. Also, binge symptoms were negatively associated with secure attachment styles, and positively with preoccupied and fearful attachment. The data, finally, provided evidence that at higher levels of preoccupied attachment, the impact of binge symptoms tended to be lower when father's care was high.

    2005-01-01

    Background: In adults, about 40% of the variance in risk of Major Depressive Disorder (MDD) is due to genetic factors, but little data exist on the heritability of youth MDD. The goal of this study was the genetic analysis of MDD in an epidemiologically and genetically representative sample of adolescent female twins. Methods: A sample of 3416 female adolescent twins systematically ascertained from birth records was assessed using a structured telephone interview that included a comprehensive DSM-IV-based section for the diagnostic assessment of MDD. Mean subject age at time of assessment was 15.5 and participation rate exceeded 85%. Genetic modeling was conducted taking into consideration the problem of censoring, i.e., that younger adolescents were not through their period of risk for adolescent onset of MDD. Results: Lifetime self-reported MDD prevalence ranged from 1% under age 12 to 17.4% at age 19 and older. The genetic variance in risk of MDD was 40.4% (95% confidence interval (CI): 23.9–55.1), with the remaining variance explained by non-shared environmental effects 59.6% (95%CI: 44.9–76.1). Shared environmental effects were not significant. A significant recall bias was observed with older respondents on average reporting later onsets for their first episode of MDD. Conclusions: The genetic and environmental contributions to risk of MDD in this representative sample of female adolescent twins are remarkably analogous to findings from adult samples. These results are congruent with a conceptualization of adolescent MDD and adult MDD as having very similar etiologic determinants. PMID:14531581

    The current study tested a developmental-contextual model of depressive symptomatology among early and middle adolescent Mexican-origin females and their mothers. The final sample was comprised of 271 dyads. We examined the interrelations among cultural (i.e., acculturation dissonance), developmental (i.e., pubertal development and autonomy expectation discrepancies), and interpersonal (i.e., mother-daughter conflict and maternal supportive parenting) factors in predicting adolescents’ depressive symptoms. For both early and middle adolescents, maternal support was negatively associated with mother-daughter conflict and depressive symptoms. Importantly, mother-daughter autonomy expectation discrepancies were positively associated with mother-daughter conflict, but this association was found only among early adolescents. Further, mother-daughter acculturation dissonance was positively associated with mother-daughter conflict, but only among middle adolescents. Findings call for concurrently examining the interface of developmental, relational, and cultural factors in predicting female adolescents’ depressive symptomatology and the potential differences by developmental stage (e.g., early vs. middle adolescence) PMID:21967564

  7. Male Age Affects Female Mate Preference, Quantity of Accessory Gland Proteins, and Sperm Traits and Female Fitness in D. melanogaster.

    2015-01-01

    For species in which mating is resource-independent and offspring do not receive parental care, theoretical models of age-based female mate preference predict that females should prefer to mate with older males as they have demonstrated ability to survive. Thus, females should obtain a fitness benefit from mating with older males. However, male aging is often associated with reductions in quantity of sperm. The adaptive significance of age-based mate choice is therefore unclear. Various hypotheses have made conflicting predictions concerning this issue, because published studies have not investigated the effect of age on accessory gland proteins and sperm traits. D. melanogaster exhibits resource-independent mating, and offspring do not receive parental care, making this an appropriate model for studying age-based mate choice. In the present study, we found that D. melanogaster females of all ages preferred to mate with the younger of two competing males. Young males performed significantly greater courtship attempts and females showed least rejection for the same than middle-aged and old males. Young males had small accessory glands that contained very few main cells that were larger than average. Nevertheless, compared with middle-aged or old males, the young males transferred greater quantities of accessory gland proteins and sperm to mated females. As a result, females that mated with young male produced more eggs and progeny than those that mated with older males. Furthermore, mating with young male reduced female's lifespan. These studies indicate that quantity of accessory gland proteins and sperm traits decreased with male age and females obtain direct fitness benefit from mating with preferred young males.

    Objectives Physical activity behavior begins to decline during adolescence and continues to decrease throughout young adulthood. This study aims to explain factors that influence physical activity behavior in a sample of female adolescents using a health promotion model framework. Methods This cross-sectional survey was used to explore physical activity behavior among a sample of female adolescents. Participants completed measures of physical activity, perceived self-efficacy, self-esteem, social support, perceived barriers, and perceived affect. Interactions among the variables were examined using path analysis within a covariance modeling framework. Results The final model accounted for an R2 value of 0.52 for physical activity and offered a good model-data fit. The results indicated that physical activity was predicted by self-esteem (β=0.46, p<0.001), perceived self-efficacy (β=0.40, p<0.001), social support (β=0.24, p<0.001), perceived barriers (β=-0.19, p<0.001), and perceived affect (β=0.17, p<0.001). Conclusions The findings of this study showed that the health promotion model was useful to predict physical activity behavior among the Iranian female adolescents. Information related to the predictors of physical activity behavior will help researchers plan more tailored culturally relevant health promotion interventions for this population. PMID:24570808

    Despite substantial evidence for the fit of the 3- and 4-factor models of Psychopathy Checklist-based ratings of psychopathy in adult males and adolescents, evidence is less consistent in adolescent females. However, prior studies used samples much smaller than recommended for examining model fit. To address this issue, we conducted a confirmatory factor analysis of 646 adolescent females to test the fit of the 3- and 4-factor models. We also investigated the fit of these models in more homogeneous subsets of the full sample to examine whether fit was invariant across geographical region and setting. Analyses indicated adequate fit for both models in the full sample and was generally acceptable for both models in North American and European subsamples and for participants in less restrictive (probation/detention/clinic) settings. However, in the incarcerated subsample, the 4-factor model achieved acceptable fit on only two of four indices. Although model fit was not invariant across continent or setting, invariance could be achieved in most cases by simply allowing factor loadings on a single Psychopathy Checklist: Youth Version (Forth, Kosson, & Hare, 2003) item to vary across groups. In summary, in contrast to prior studies with small samples, current findings show that both the 3- and 4-factor models fit adequately in a large sample of adolescent females, and the factor loadings are largely similar for North American and European samples and for long-term incarcerated and shorter-term incarcerated/probation/clinic samples.

    Despite substantial evidence for the fit of the three- and four-factor models of Psychopathy Checklist-based ratings of psychopathy in adult males and adolescents, evidence is less consistent in adolescent females. However, prior studies used samples much smaller than recommended for examining model fit. To address this issue, we conducted a confirmatory factor analysis of 646 adolescent females to test the fit of the three- and four-factor models. We also investigated the fit of these models in more homogeneous subsets of the full sample to examine whether fit was invariant across geographical region and setting. Analyses indicated adequate fit for both models in the full sample and was generally acceptable for both models in North American and European subsamples and for participants in less restrictive (probation/detention/clinic) settings. However, in the incarcerated subsample, the four-factor model achieved acceptable fit on only two of four indices. Although model fit was not invariant across continent or setting, invariance could be achieved in most cases by simply allowing factor loadings on one PCL: YV item to vary across groups. In summary, in contrast to prior studies with small samples, current findings show that both the three- and four-factor models fit adequately in a large sample of adolescent females, and the factor loadings are largely similar for North American and European samples and for long-term incarcerated and shorter-term incarcerated/probation/clinic samples.

    Endobronchial carcinoid tumors are the most common intrabronchial tumors in children and adolescents. Common signs and symptoms include persistent cough and wheezing not responsive to bronchodilators, hemoptysis, and recurrent fever. Diagnosis is frequently made by imaging and direct visualization with flexible bronchoscopy; surgery remains the gold standard treatment, and lung-sparing resections should be performed whenever possible. Though carcinoid syndrome—characterized by flushing, palpitations, wheezing, shortness of breath, and diarrhea—has been found in association with adult bronchial carcinoid tumors, to our knowledge only one previous study has reported the presence of carcinoid syndrome in a pediatric patient with an endobronchial carcinoid. Here, we report a case of a 14-year-old girl with chronic cough found to have an endobronchial carcinoid tumor and signs and symptoms consistent with carcinoid syndrome. PMID:27895950

    To examine whether perceived peer/parent norms or personal beliefs about adolescent substance use influence substance use among female adolescents with chronic medical conditions. Sixty-eight females reported on substance use, personal beliefs, and perceived peer/parent norms. Personal beliefs and perceived peer/parent norms were associated with adolescent's current and future substance use. Although perceived peer norms accounted for variance in current substance use, only personal beliefs accounted for variance in future alcohol use. Targeting perceived peer norms may be effective for intervention efforts among adolescents endorsing current substance use, whereas alcohol use prevention efforts should target personal beliefs.

    Purpose Different relative aerobic energy contribution (WAER%) has been reported for the two female Olympic kayaking disciplines (i.e. 200 and 500m). The purpose of this study was to investigate whether the adopted method of energy calculation influenced the value of WAER% during the kayaking time trials. Methods Eleven adolescent female kayakers (age 14±1 yrs, height 172±4 cm, body mass 65.4±4.2 kg, VO2peak 42.6±4.9 ml·min(-1)·kg(-1), training experience 1.5±0.3 yrs) volunteered to participate in one incremental exercise test and two time trials (40s and 120s) on the kayak ergometer. A portable spirometric system was used to measure gas metabolism. Capillary blood was taken from the ear lobe during and after the tests, and analyzed for lactate afterwards. The method of modified maximal accumulated oxygen deficit (m-MAOD) and the method based on the fast component of oxygen uptake off-kinetics (PCr-La-O2) were utilized to calculate the energy contributions. Results The anaerobic energy portions from m-MAOD were lower than those from PCr-La-O2 in the 40s (41.9±8.8 vs. 52.8±4.0 kJ, p<0.05) and 120s (64.1±27.9 vs. 68.2±10.0 kJ, p>0.05) time trials, which induced differences of WAER% between m-MAOD and PCr-La-O2 (36.0 vs. 30.0% in 40s, p<0.05; 60.9 vs. 57.5% in 120s, p>0.05). Conclusions The reported different WAER% in the female Olympic kayaking could be partly attributed to the adopted method of energy calculation (i.e. m-MAOD vs. PCr-La-O2). A fixed method of energy calculation is recommended during the longitudinal assessment on the relative energy contribution in female Olympic kayaking.

    Background: Despite clear reasons for necessity of sexual health education for adolescents, it is a contested issue and has faced challenges in most cultures. Providing sexual education for non-married adolescents is culturally unacceptable in most Muslim societies. Objective: This qualitative study addressed socio-cultural challenges to sexual health education for female adolescents in Iran. Materials and Methods: Qualitative data from female adolescents (14-18 yr), mothers, teachers, authorities in health and education organizations, health care providers and clergies were collected in two large cities of Iran including Mashhad and Ahvaz through focus group discussions and individual in-depth interviews. Data were analyzed using conventional qualitative content analysis with MAXqda software. Results: Our results revealed that the main socio-cultural challenges to sexual health education for adolescents in Iran are affected by taboos surrounding sexuality. The emergent categories were: denial of premarital sex, social concern about negative impacts of sexual education, perceived stigma and embarrassment, reluctance to discuss sexual issues in public, sexual discussion as a socio-cultural taboo, lack of advocacy and legal support, intergenerational gap, religious uncertainties, and imitating non-Islamic patterns of education. Conclusion: It seems that cultural resistances are more important than religious prohibitions, and affect more the nature and content of sexual health education. However, despite existence of salient socio-cultural doubtful issues about sexual health education for adolescents, the emerging challenges are manageable to some extent. It is hoped that the acceptability of sexual health education for adolescents could be promoted through overcoming the cultural taboos and barriers as major obstacles. PMID:24639734

    There is a growing need to accurately assess exercise energy expenditure (EEE) in athletic populations that may be at risk for health disorders because of an imbalance between energy intake and energy expenditure. The Actiheart combines heart rate and uniaxial accelerometry to estimate energy expenditure above rest. The authors' purpose was to determine the utility of the Actiheart for predicting EEE in female adolescent runners (N = 39, age 15.7 ± 1.1 yr). EEE was measured by indirect calorimetry and predicted by the Actiheart during three 8-min stages of treadmill running at individualized velocities corresponding to each runner's training, including recovery, tempo, and 5-km-race pace. Repeated-measures ANOVA with Bonferroni post hoc comparisons across the 3 running stages indicated that the Actiheart was sensitive to changes in intensity (p < .01), but accelerometer output tended to plateau at race pace. Pairwise comparisons of the mean difference between Actiheart- and criterion-measured EEE yielded values of 0.0436, 0.0539, and 0.0753 kcal × kg-1 × min-1 during recovery, tempo, and race pace, respectively (p < .0001). Bland-Altman plots indicated that the Actiheart consistently underestimated EEE except in 1 runner's recovery bout. A linear mixed-model regression analysis with height as a covariate provided an improved EEE prediction model, with the overall standard error of the estimate for the 3 speeds reduced to 0.0101 kcal × kg-1 × min-1. Using the manufacturer's equation that combines heart rate and uniaxial motion, the Actiheart may have limited use in accurately assessing EEE, and therefore energy availability, in young, female competitive runners.

    Achievement goal theory has long been a dominant model in the study of student motivation. However, a relatively small number of researchers have investigated gender differences in achievement goals or have considered the possible role that social and extrinsic goals may play in student academic motivation. Adopting a person-centered multiple goals perspective based on personal investment theory, this longitudinal study investigated whether males and females shared similar goal profiles, and whether the predictors (facilitating conditions) and outcomes (learning processes, task perseverance, and future aspirations) of these profiles were equivalent across genders. Profiles were extracted from 8 types of academic goals, based on a large sample of Hong Kong high school students (N = 7,848). Findings revealed 5 distinctive profiles for both males and females. Although the relative size of these profiles differed across samples of male and female students, the results show that 4 of these profiles were mostly equivalent across genders. Predictors of membership into these profiles were also equivalent across genders, whereas their relative outcomes were specific to gender. (PsycINFO Database Record

    Health status is often analyzed in population surveys. Self-rated health (SRH) is a single-item summary measure of the perception of one's health. In Brazil, studies on the SRH of adolescents remain scarce, especially those aiming to understand the domains that compose this construct. Therefore, the aim of this study is to determine the prevalence of poor SRH and its associated factors among 11- to 13-year-olds and 14- to 17-year-olds living in a large urban center in Brazil. This cross-sectional study was conducted using a household survey across Belo Horizonte that included 1,042 adolescents. Stratified logistic regression models were used for each age group to assess the associations between worse SRH and the following variables: socio-demographic, social and family support, lifestyles, psychological health, and anthropometry. Approximately 11% (95% CIs = 8.7-13.6) of the studied adolescents rated their health as poor, and SHR decreased with age among males and females. This trend was more pronounced among girls (from 6.9% among 11- to 13-year-old girls to 16.9% among 14- to 17-year-old girls) than boys (from 8.3% among 11- to 13-year-old boys to 11% among 14- to 17-year-old boys). Worse SRH was associated with family support (as assessed by the absence of parent-adolescent conversations; odds ratio [OR] = 3.5 among 11- to 13-year-olds), family structure (OR = 2.8 among 14- to 17-year-olds), and argument reporting (OR = 8.2 among 14- to 17-year-olds). Among older adolescents, the consumption of fruit fewer than five times per week (OR = 2.4), life dissatisfaction (OR = 2.8), underweight status (OR = 6.7), and overweight status (OR = 2.7) were associated with poor SRH. As adolescents age, their universe expands from their relationship with their parents to include more complex issues, such as their lifestyles and life satisfaction. Therefore, these results suggest the importance of evaluating SRH across adolescent age groups and demonstrate the influence of the

    Thirty-one adolescent females, aged 14 to 20 years, underwent cholecystectomy for pathologically documented cholesterol gallstones. A retrospective study, using the Mantel-Haenzel method of statistical analysis, showed a strong association between cholesterol cholelithiasis and obesity and parity. The patients with gallstones had a higher rate of oral contraceptive use, which just failed to attain statistical significance. These findings indicate that adolescent cholelithiasis is largely preventable. Dietary obesity can be controlled by balanced diets and physical exercise. Early pregnancy should be discourgaed, espeically if there is a strong family history of cholelithiasis and if weight control is unsuccessful. Oral contraceptives should be used cautiously in the presence of other predisposing factors.

    The transition into menopause is a complex process that affects fertility and increases the risk for a number of health problems in aging women that include, but are not limited to osteoporosis, heart disease, diabetes mellitus and cognitive dysfunction. Improved nutrition and enhanced access to medical care have increased the average lifespan for women in developed countries, and many will spend more than one-third of their life in a post-menopausal state. Epidemiological studies indicate that a delayed natural menopause confers longevity and decelerates the appearance of much age-related morbidity, suggesting that developing treatments to delay menopause would significantly improve quality of life for women. Although menopause is ultimately defined by ovarian follicular exhaustion, several lines of scientific evidence in humans and animals now suggest that dysregulation of estradiol feedback mechanisms and hypothalamic-pituitary dysfunction contributes to the onset and progression of reproductive senescence, independent of ovarian failure. This article provides a brief update on our current understanding of the role of the hypothalamic-pituitary axis in the onset of and transition into female reproductive senescence.

    Is Female Genital Cosmetic Surgery for an adolescent with Body Dysmorphic Disorder ever ethically justified? Cosmetic genital surgery (specifically labioplasty) for adolescent girls is one of the most ethically controversial forms of cosmetic surgery and Body Dysmorphic Disorder is typically seen as a contraindication for cosmetic surgery. Two key ethical concerns are (1) that Body Dysmorphic Disorder undermines whatever capacity for autonomy the adolescent has; and (2) even if there is valid parental consent, the presence of Body Dysmorphic Disorder means that cosmetic surgery will fail in its aims. In this article, we challenge, in an evidence-based way, the standard view that Body Dysmorphic Disorder is a contraindication for genital cosmetic surgery in adolescents. Our argument gathers together and unifies a substantial amount of disparate research in the context of an ethical argument. We focus on empirical questions about benefit and harm, because these are ethically significant. Answers to these questions affect the answer to the ethical question. We question the claim that there would be no benefit from surgery in this situation, and we consider possible harms that might be done if treatment is refused. For an adolescent with Body Dysmorphic Disorder, the most important thing may be to avoid harm. We find ourselves arguing for the ethical justifiability of cosmetic labioplasty for an adolescent with Body Dysmorphic Disorder, even though we recognize that it is a counter intuitive position. We explain how we reached our conclusion.

    This study aimed to estimate the prevalence of abdominal obesity and investigate their association with parameters markers of metabolic syndrome (MS) and its risk factors in female adolescents. It is a cross-sectional study with 150 adolescents from 10 public schools in the Federal District, Brazil. The presence of abdominal obesity was considered by measuring waist circumference above the 80th percentile, according to Taylor et al. (2000). The associated factors included sociodemographic characteristics, health status of adolescents and their parents, physical activity, eating habits, blood pressure and biochemical profile. The abdominal obesity prevalence ratio (PR) was estimated by Poisson regression model, with 95% CI. Among the adolescents studied (age= 15.6 +/- 0.8 years; BMI = 21.0 +/- 3.0 kg/m2), prevalence of abdominal obesity was 20%, and this condition was not associated with sociodemographic variables, physical activity and diet. However, abdominal obesity was significantly associated with intake of less than 4 meals a day (PR = 2.27; IC95% 1.27-4.10), previous obesity (PR = 2.36; IC95% 1.31-4.01), history of parental chronic disease (PR = 3.55; IC 95% 1.63-7.75), fasting insulin = 15 uUi/mL (PR = 3.05; IC 95% 1.36-6.82) e HDL-c > 40 mg/dL (PR = 0.39; IC95% 0.23-0.67). In this population, modifiable factors, family history and determinants of MS, such as insulin and HDL-c were associated with abdominal obesity, which points to the need for effective health promotion among adolescents.

    The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality.

    The objective of the study was to compare the prevalence of self-reported physician-diagnosed asthma and age at asthma onset between Swedish adolescent elite skiers and a reference group and to assess risk factors associated with asthma. Postal questionnaires were sent to 253 pupils at the Swedish National Elite Sport Schools for cross-country skiing, biathlon, and ski-orienteering ("skiers") and a random sample of 500 adolescents aged 16-20, matched for sport school municipalities ("reference"). The response rate was 96% among the skiers and 48% in the reference group. The proportion of participants with self-reported physician-diagnosed asthma was higher among skiers than in the reference group (27 vs. 19%, p = 0.046). Female skiers reported a higher prevalence of physician-diagnosed asthma compared to male skiers (34 vs. 20%, p = 0.021). The median age at asthma onset was higher among skiers (12.0 vs. 8.0 years; p < 0.001). Female sex, family history of asthma, nasal allergy, and being a skier were risk factors associated with self-reported physician-diagnosed asthma. Swedish adolescent elite cross-country skiers have a higher asthma prevalence and later age at asthma onset compared to a reference population. Being an adolescent elite skier is an independent risk factor associated with asthma. This article is protected by copyright. All rights reserved.

Method Interviews with 102 urban African American and Hispanic adolescent females examined physical abuse, emotional/verbal abuse, and threats, and their unique and combined associations with depression. Results One-quarter of the sample experienced all three types of abuse. Non-physical forms of IPV were significantly associated with depression. Conclusions Some urban adolescent females from lower income households experience high rates of IPV.

    In the present study we examined how genotype-environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother-adolescent and father-adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and non-passive genotype-environment correlation based on biometric moderation findings. Findings indicated that non-passive rGE played a stronger role for positivity in mother- and father- adolescent relationships in families with older adolescents than families with younger adolescents, and that passive rGE played a stronger role for positivity in the mother-adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed. PMID:25924807

    Social anxiety is a common psychological disorder that often emerges during adolescence and is associated with significant impairment. Efforts to prevent social anxiety disorder require sound assessment measures for identifying anxious youth, especially those from minority backgrounds. We examined the factorial invariance and latent mean differences of the Social Anxiety Scale for Adolescents (SAS-A) across gender and age groups in Hispanic American adolescents (N = 1,191; 56% girls; 15-18 years) using multigroup confirmatory factor analyses. Results indicated that the factorial configuration of the correlated three-factor model of the SAS-A was invariant across gender and age. Analyses of latent mean differences revealed that boys exhibited higher structured means than girls on the Social Avoidance and Distress-General (SAD-General) subscale. On all SAS-A subscales, Fear of Negative Evaluation, Social Avoidance and Distress-New, and SAD-General, estimates of the structured means decreased with adolescent age. Implications for further research and clinical practice are discussed.

    Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N=191; 52.4% female) between the ages of 11 and 18 (M=14.4 years, SD=1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of five adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

    2007-01-01

    Background By mid adolescence there is an excess in female physical and/or psychosomatic, as well as psychological morbidity. This paper examines the contribution of a range of factors (self-esteem, body image, gender-role orientation, body mass index, smoking and physical activity) to explaining the female excess in three psychosomatic symptoms (headaches, stomach ache/sickness, and dizziness) and depressive mood at age 15. Methods A cohort of 2,196 school pupils (analyses restricted to 2,005 with complete data) surveyed at age 15. All measures were obtained via self-completion questionnaires, apart from body mass index, derived from measured height and weight. Analyses examined (a) sex differences in each potential explanatory factor; (b) their associations with the health measures; (c) the effect of adjustment for these factors on sex differences in the health measures; and (d) the existence of interactive effects between sex and the explanatory factors on the health measures Results Each potential explanatory factor was significantly differentiated by sex. Self-esteem, body image (represented by weight-related worries), smoking and physical activity were related to the health measures. These factors accounted for one third of the female excess in headaches and stomach problems, half the excess in dizziness and almost all that in respect of depressive mood. Self-esteem and body image were the factors most consistently related to health, and adjustment for these resulted in the largest reductions in the odds of a female excess in both the psychosomatic symptoms and depressive mood. Conclusion Adjustment for a range of potential psychosocial and behavioural factors largely explains (statistically) excess female depressive mood. These factors also partially explain the female excess in certain psychosomatic symptoms. PMID:17953744

Materials and Methods: Adolescent (n = 102, aged 15.2 ± 2.0 year) and adult (n = 57, 25.9 ± 5.0 year) players were examined for anthropometric characteristics and body composition, and performed the physical working capacity in heart rate 170 min-1 test, a force-velocity test, the Wingate anaerobic test (WAnT), sit-and-reach test (SAR), handgrip strength test (HST) and countermovement vertical jump (CVJ). Results: Based on international BMI cut-off points, 27.5% (n = 28) of adolescent and 12.3% (n = 7) of adult participants were classified as overweight, with the prevalence of overweight being higher in girls than in women (χ2 = 4.90, P = 0.027). BMI was correlated with BF in both age groups (r = 0.72, P < 0.001 in girls; r = 0.75, P < 0.001 in women). Normal participants had superior certain physical and physiological characteristics than those who were overweight. For instance, normal girls and women had higher mean power during WAnT than their overweight counterparts (P = 0.003 and P = 0.009 respectively). Except for flexibility, BMI and BF were inversely related with physical fitness (e.g., BMI vs. HST r = -0.39, P < 0.001 in girls; BF vs. CVJ r = -0.45, P < 0.001 in women). Conclusion: The findings confirmed the negative effect of overweight and fatness on selected parameters of physical fitness. The prevalence of overweight in adolescent volleyball players was higher than in general population, which was a novel finding, suggesting that proper exercise interventions should be developed to target the excess of body mass in youth volleyball clubs.

    ABSTRACT Purpose Knee abduction moment (KAM) is an injury risk factor for anterior cruciate ligament (ACL) injury that shows divergent incidence between males and females during adolescence. The objective of this study was to determine the relation between skeletal growth and increased KAM. The hypotheses tested were that females would demonstrate peak KAM during landing at peak height velocity (PHV) and that they would diverge from males at PHV. Methods The subject pool consisted of 674 females and 218 males (1387 female and 376 male assessments) who participated in a preseason testing session before their basketball or soccer seasons. They were tested longitudinally for multiple years (2 ± 1 yr) to capture maturation via estimates of percent (%) adult stature and biomechanical analysis during a drop vertical jump maneuver. Data were analyzed using three-dimensional motion analysis that used a 37 retroreflective marker body model and inverse dynamics to calculate segment joint centers and peak KAM. Results Mature females, as defined as 92% adult stature or greater, displayed increased peak KAM and knee abduction angles relative to growing (≤91% adult stature) adolescent females (P < 0.001). A significant sex–maturation (% adult stature) interaction (P < 0.001) in peak KAM was observed. Post hoc analyses showed consistent sex differences in groups greater than or equal to, but not less than, 92% adult stature, which is approximately at PHV. Hence, sex differences in peak KAM and PHV coincide. Conclusions Increases in peak KAM during and after PHV seem to coincide with increased risk of ACL injury in females. KAM peaked in females at PHV. Tracking longitudinal increases in peak KAM may be useful for the identification of females at increased risk of ACL injury. PMID:25970663

    Background Biobehavioural research methodology can be invasive and burdensome for participants—particularly adolescents with mental illnesses. Human biological researchers should consider how methodological impositions may hinder adolescent research participation. However, literature on adolescent’s voices and concerns toward biobehavioural research participation is virtually non-existent. Aim This study was designed to determine adolescents’ perceptions of participation in research involving the collection of biomarkers via blood, saliva and/or urine samples. Subjects and methods Urban adolescent females (aged 12–19) receiving outpatient mental health treatment (n = 37) participated in focus groups with concurrent survey administration to explore attitudes, beliefs and willingness/intentions toward biobehavioural research participation. Results Participants had favourable attitudes toward biobehavioural research and were amenable to provide each specimen type. Mistrust for research emerged, however, and concerns related to privacy and confidentiality were expressed. Conclusion Participant recruitment is a critical component in study design and implementation; this includes knowledge of population-specific recruitment barriers and facilitators. This innovative paper provides a context for the research participants’ decision-making process, strategies to allay fears and concerns and concrete areas to target in research-related interventions. Although the findings are from a specific, US-based sample, the implications warrant replication of the research in other geosocial settings. PMID:23822716

    Tubo-ovarian abscess (TOA) is a common acute complication of pelvic inflammatory disease (PID). It can also develop as a complication of pelvic or abdominal surgery, malignancy, and intra-abdominal processes such as appendicitis. In premenopausal women, PID is the most common cause of tubo-ovarian abscess. We report a case of tubo-ovarian abscess in a virginal adolescent female with no past surgical history and no known history of appendicitis, inflammatory bowel disease, or cancer. Cultures of the tubo-ovarian abscess drainage grew Abiotrophia/Granulicatella species. This case supports including TOA in the broad differential diagnosis for abdominal pain with fever in adolescent females regardless of sexual history.

    Adolescents are the highest consumers of sugar sweetened drinks. Excessive consumption of such drinks is a likely contributor to the development of obesity and may be associated with enduring changes in the systems involved in reward and motivation. We examined the impact of daily sucrose consumption in young male and female rats (N=12 per group) across the adolescent period on the motivation to perform instrumental responses to gain food rewards as adults. Rats were or were not exposed to a sucrose solution for 2 h each day for 28 days across adolescence [postnatal days (P) 28-56]. They were then trained as adults (P70 onward) to lever press for a palatable 15% cherry flavored sucrose reward and tested on a progressive ratio (PR) schedule to assess motivation to respond for reinforcement. Female rats exposed to sucrose had higher breakpoints on the PR schedule than controls, whereas male rats exposed to sucrose had lower breakpoints than controls. These results show that consumption of sucrose during adolescence produced sex-specific behavioral changes in responding for sucrose as adults.

    Depression during pregnancy has been linked to in utero stress and is associated with long-lasting symptoms in offspring, including anxiety, helplessness, attentional deficits, and social withdrawal. Depression is diagnosed in 10-20% of expectant mothers, but the impact of antidepressant treatment on offspring development is not well documented, particularly for females. Here, we used a prenatal stress model of maternal depression to test the hypothesis that in utero antidepressant treatment could mitigate the effects of prenatal stress. We also investigated the effects of prenatal stress and antidepressant treatment on gene expression related to GABAergic and serotonergic neurotransmission in the amygdala, which may underlie behavioral effects of prenatal stress. Nulliparous female rats were implanted with osmotic minipumps delivering clinically-relevant concentrations of escitalopram and mated. Pregnant dams were exposed to 12 days of mixed-modality stressors, and offspring were behaviorally assessed in adolescence (postnatal day 28) and adulthood (beyond day 90) to determine the extent of behavioral change. We found that in utero stress exposure, regardless of escitalopram treatment, increased anxiety-like behavior in adolescent females and profoundly influenced amygdala expression of the chloride transporters KCC2 and NKCC1, which regulate GABAergic function. In contrast, prenatal escitalopram exposure alone elevated amygdala expression of 5-HT1A receptors. In adulthood, anxiety-like behavior returned to baseline and gene expression effects in the amygdala abated, whereas deficits emerged in novel object recognition for rats exposed to stress during gestation. These findings suggest prenatal stress causes age-dependent deficits in anxiety-like behavior and amygdala function in female offspring, regardless of antidepressant exposure. PMID:26032436

    Improved survival rates among reproductive-age females diagnosed with cancer have increased the focus on long-term quality of life, including maintenance of the ability to conceive biological children. Cancer-directed therapies such as high-dose alkylating agents and radiation to the pelvis, which deplete ovarian reserve, radiation to the brain, which affects the hypothalamic-pituitary-gonadal axis, and surgical resection of reproductive structures can decrease the likelihood of having biological children. Standard fertility preservation strategies such as embryo and oocyte cryopreservation before the onset of therapy offer the opportunity to conserve fertility, but they may not be feasible because of the urgency to start cancer therapy, financial limitations, and a lack of access to reproductive endocrinologists. Ovarian tissue freezing is considered experimental, with limited data related to pregnancies, but it minimizes treatment delay. Studies evaluating gonadotropin-releasing hormone analogues have had mixed results, although a recent randomized, prospective study in women with breast cancer demonstrated a protective effect. Fertility preservation programs are increasingly being developed within cancer programs. In this article, we describe risks to infertility and options for preservation, raise psychosocial and ethical issues, and propose elements for establishing an effective fertility preservation program.

    Age, height and weight are intricately related to performance in a specific sporting activity. Optimum standards derived from 32 female Olympic finalists from two jumping events are listed as a sample from a much larger set of 824 finalists from 47 events. An example of variation is that high jumpers are taller by 6.3 cm and younger by 2.9 years than long jumpers. Conversely, considerable variation in body weight is shown for a group of finalists all with a height of 171 cm. The weights of these finalists range from 56 kg for a 400 m runner to 85 kg for a discus thrower. Many other events are listed between these examples and a number of events are found to share the same combination of height and weight (height 171 cm, weight 59-62 kg) swimming freestyle and medley, 200 m run, rowing, canoeing, volleyball and handball. These findings are expected to be of use for potential champions looking for optimum standards in specific events. They are also of use for trainers counselling athletes in the most appropriate selection of the event befitting her physique. Many sporting activities are found to be seriously biased in favour of the taller members of the population. This is a cause for concern as is the need for some remedial action.

    Ancient human mobility at the individual level is conventionally studied by the diverse application of suitable techniques (e.g. aDNA, radiogenic strontium isotopes, as well as oxygen and lead isotopes) to either hard and/or soft tissues. However, the limited preservation of coexisting hard and soft human tissues hampers the possibilities of investigating high-resolution diachronic mobility periods in the life of a single individual. Here, we present the results of a multidisciplinary study of an exceptionally well preserved circa 3.400-year old Danish Bronze Age female find, known as the Egtved Girl. We applied biomolecular, biochemical and geochemical analyses to reconstruct her mobility and diet. We demonstrate that she originated from a place outside present day Denmark (the island of Bornholm excluded), and that she travelled back and forth over large distances during the final months of her life, while consuming a terrestrial diet with intervals of reduced protein intake. We also provide evidence that all her garments were made of non-locally produced wool. Our study advocates the huge potential of combining biomolecular and biogeochemical provenance tracer analyses to hard and soft tissues of a single ancient individual for the reconstruction of high-resolution human mobility.

    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.

    Female remating behaviour is a key mating system parameter that is predicted to evolve according to the net effect of remating on female fitness. In many taxa, females commonly resist male remating attempts because of the costs of mating. Here, we use replicated populations of the seed beetle Acanthoscelides obtectus selected for either early or late life reproduction and show that ‘Early’ and ‘Late’ females evolved different age-specific rates of remating. Early females were more likely to remate with control males as they aged, while Late females were more resistant to remating later in life. Thus, female remating rate decreases with age when direct selection on late-life fitness is operating and increases when such selection is relaxed. Our findings not only demonstrate that female resistance to remating can evolve rapidly, but also that such evolution is in accordance with the genetic interests of females. PMID:17148327

    To our knowledge, there are no former studies in which subgroups of female adolescent sexual offenders are studied. Therefore, we examined differences in risk factors for general recidivism between female adolescents who have committed a felony sexual offense against a younger child (CSO, n=25), female adolescents who have committed a felony sexual offense with a peer victim (PSO, n=15) and female adolescents who have committed a misdemeanor sexual offenses (MSO, n=31). Results showed that CSOs had considerably fewer problems in the domains of school (truancy, behavior problems, dropping out of school), family (e.g., parental alcohol problems, parental mental health problems, poor authority and control, out of home placements and run away from home) and friends (antisocial friends) than MSOs and/or PSOs. No differences were found in the prevalence of mental health problems, physical abuse, sexual abuse and neglect. Implications for theory and practice are discussed.

    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

    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.

    A low chronologic age (less than or equal to 15 years) and low gynecologic age (less than or equal to 2 years) have been considered factors that increase medical complications among adolescent pregnant women. Gynecologic age (GA) is defined in this study as age in years at conception minus age at menarche. Two hundred twelve consecutive pregnant teenagers were followed prospectively in the Teen OB Clinic at the University of California, San Diego Medical Center, between August 1978 and July 1981. The clinic population consisted of 37.3 percent Whites, 35.8 percent Hispanics, 20.8 percent Blacks, and 6.1 percent other (mostly Indochinese). Sixty-eight percent of the patients were funded by MediCal. The patient population was divided by chronological age (CA) at conception into those 15 years or less or 16 years or older. A low chronological age was found to be a significant risk factor for premature rupture of membranes. Teenagers with a low gynecologic age (less than or equal to 2) had a lower mean pre-pregnancy weight and body mass index (Kg/M2) than teenagers with a higher gynecologic age. In this study, we did not find that a low CA or GA was correlated with a higher frequency of pregnancy-induced hypertension, prenatal medical problems, obstetrical problems at labor or delivery, or an excessive number of low-birthweight infants.

    Competition between females is particularly intense in cooperatively breeding mammals, where one female monopolises reproduction in each group. Chronic competition often affects stress and may therefore have long-term consequences for fitness, but no studies have yet investigated whether intrasexual competition has effects of this kind and, in particular, whether it affects rates of reproductive senescence. Here, we use long-term data from a wild population of meerkats to test whether reproductive success and senescence in dominant females are affected by the degree of intrasexual competition experienced prior to dominance acquisition. Females that experienced greater competition had lower breeding success and higher rates of reproductive senescence. Furthermore, females that were evicted from the group more frequently as subordinates had lower breeding success when dominant. We conclude that the intense intrasexual competition between females in cooperatively breeding groups may carry fitness costs over a longer period than is usually recognised.

    Human papillomavirus (HPV) vaccine uptake among 18–26 y old women varies by geographic region in the US. However, little is known about regional variations in vaccination among girls who are in the vaccine's targeted age groups. Regional variation in HPV vaccination among female adolescents (9–17 y old) was examined using cross-sectional data from the Behavioral Risk Factor Surveillance System (BRFSS) between 2008 and 2010. Multivariable logistic regression estimated the association of region of residence (10 states included questions about adolescent HPV vaccination) with uptake and completion of the 3-shot HPV vaccine series. Among 7,849 adolescents, 26.9% initiated, and 55.2% of initiators completed the series. Adolescents from Northeast/Midwest/West states were 1.74 (95% CI: 1.45-2.10) times more likely to have initiated HPV vaccination compared to the South/Southwestern states. Among initiators, vaccine series completion did not vary significantly between the South/Southwestern and Northeast/Midwest/West states. Flu vaccination was associated with increased odds of initiation in both regions and completion of the HPV vaccine series in the South/Southwestern states only. Girls 9–10 and 11–12 y old were less likely to have initiated and 11–12 y olds were less likely to have completed the HPV vaccine series compared to 13–17 y olds. The observed regional variations in vaccination could cause rates of cervical cancer to remain higher in the South/Southwest and widen currently observed regional disparities in cervical cancer rates.

    The experience of child maltreatment is a known risk factor for the development of psychopathology. Structural and functional modifications of neural systems implicated in stress and emotion regulation may provide one mechanism linking early adversity with later outcome. The authors examined two well-documented biological markers of stress vulnerability [resting frontal electroencephalogram (EEG) asymmetry and cardiac vagal tone] in a group of adolescent females exposed to child maltreatment (n = 38; M age = 14.47) and their age-matched non-maltreated (n = 25; M age = 14.00) peers. Maltreated females exhibited greater relative right frontal EEG activity and lower cardiac vagal tone than controls over a 6-month period. In addition, frontal EEG asymmetry and cardiac vagal tone remained stable in the maltreated group across the 6 months, suggesting that the neurobiological correlates of maltreatment may not simply reflect dynamic, short-term changes but more long lasting alterations. The present findings appear to be the first to demonstrate stability of two biologically based stress-vulnerability measures in a maltreated population. Findings are discussed in terms of plasticity within the neural circuits of emotion regulation during the early childhood period and alternative causal models of developmental psychopathology.

  2. Female adolescents and their sexuality: notions of honour, shame, purity and pollution during the floods.

    This paper explores the experiences of female adolescents during the 1998 floods in Bangladesh, focusing on the implications of socio-cultural norms related to notions of honour, shame, purity and pollution. These cultural notions are reinforced with greater emphasis as girls enter their adolescence, regulating their sexuality and gender relationships. In Bangladeshi society, adolescent girls are expected to maintain their virginity until marriage. Contact is limited to one's family and extended relations. Particularly among poorer families, adolescent girls tend to have limited mobility to safeguard their 'purity'. This is to ensure that the girl's reputation does not suffer, thus making it difficult for the girl to get married. For female adolescents in Bangladesh, a disaster situation is a uniquely vulnerable time. Exposure to the unfamiliar environment of flood shelters and relief camps, and unable to maintain their 'space' and privacy from male strangers, a number of the girls were vulnerable to sexual and mental harassment. With the floods, it became difficult for most of the girls to be appropriately 'secluded'. Many were unable to sleep, bathe or get access to latrines in privacy because so many houses and latrines were under the water. Some of the girls who had begun menstruation were distressed at not being able to keep themselves clean. Strong social taboos associated with menstruation and the dirty water that surrounded them made it difficult for the girls to wash their menstrual cloths or change them frequently enough. Many of them became separated from their social network of relations, which caused them a great deal of anxiety and stress. Their difficulty in trying to follow social norms have had far-reaching implications on their health, identity, family and community relations.

    Low levels of human papillomavirus (HPV) awareness and knowledge have been observed in the few studies conducted among school-going adolescents. Such data are lacking in Germany. To assess awareness of HPV and of vaccination status among girls attending grades 8-13 in Bremen and Bremerhaven, two German cities. Participants completed a questionnaire in school including questions on demographic characteristics, about HPV awareness and on vaccination status. We analysed the relationship between awareness of HPV, of vaccination status and vaccine uptake and several variables including age and migrant background using univariate and multivariate logistic regression. Six hundred and thirty-two girls aged 12-20 years completed the questionnaire. 50 % had no awareness of HPV, 12 % reported being vaccinated against HPV and 57 % did not know whether or not they were vaccinated against HPV. In multivariate analyses, ever had sex was associated with awareness of HPV, and ever been to a gynaecologist with awareness of vaccination status. Our results may be an indication that female adolescents in Germany are not adequately informed and counselled about HPV and associated issues.

    Abstract Objective: to verify the association among the knowledge attitude and practice of women in relation to the smear test and the age range. Method: a cross-sectional research was undertaken, associated with the knowledge, attitude and practice survey at a Primary Health Care service. The sample consisted of 775 women, distributed in three age ranges: adolescent, young and elderly. Results: although high rates of inappropriate knowledge were found in all age ranges, it was significantly higher among the adolescents (p=0.000). A similar trend was found in the attitude component, with percentages of inappropriateness in adolescence that drop as age advances (p=0.000). Nevertheless, no statistical difference among the groups was found in terms of practice (p=0.852). Conclusion: the study demonstrated a relation between the age range and knowledge, attitude and practice of the smear test. PMID:27305183

    Human adolescents often consume alcohol in a binge-like manner at a time when changes are occurring within specific brain structures, such as the medial prefrontal cortex (mPFC) and the basolateral nucleus of the amygdala (BLN). In particular, neuron and glia number are changing in both of these areas in the rat between adolescence and adulthood (Markham et al., 2007; Rubinow and Juraska, 2009). The current study investigated the effects of ethanol exposure during adolescence on the number of neurons and glia in the adult mPFC and BLN in Long-Evans male and female rats. Saline or 3 g/kg ethanol was administered between postnatal days (P) 35–45 in a binge-like pattern, with 2 days of injections followed by 1 day without an injection. Stereological analyses of the ventral mPFC (prelimbic and infralimbic areas) and the BLN were performed on brains from rats at 100 days of age. Neuron and glia densities were assessed with the optical disector and then multiplied by the volume to calculate the total number of neurons and glia. In the adult mPFC, ethanol administration during adolescence resulted in a decreased number of glia in males, but not females, and had no effect on the number of neurons. Adolescent ethanol exposure had no effects on glia or neuron number in the BLN. These results suggest that glia cells in the prefrontal cortex are particularly sensitive to binge-like exposure to ethanol during adolescence in male rats only, potentially due to a decrease in proliferation in males or protective mechanisms in females.

    Using survey methodology, this exploratory study examined the attitudinal and perceptual dimensions of body image among 1,272 eighth- and ninth-grade males and females from higher and lower socioeconomic backgrounds in Buenos Aires, Argentina (n = 195), Guatemala City, Guatemala (n = 212), Havana, Cuba (n = 213), Lima, Peru (n = 218), Panama City, Panama (n = 195), and Santiago, Chile (n = 239). The two dimensions of body image were assessed by showing the participants nine male and nine female silhouettes depicting body sizes ranging from extremely thin (#1) to extremely obese (#9). Approximately 50% of the male and female adolescents chose silhouette #3 as best depicting the attractive male body. Silhouette #2 was chosen by 45% of the females as best depicting feminine attractiveness, while 45% of the males chose silhouette #3. When identifying the silhouette that best depicted the healthy male body, 26% of the participants chose silhouette #2, 41% chose #3, and 19% chose #4. Silhouette #2 was selected by 33% of the adolescents as best depicting the healthy female body, 38% chose #3, and 14% chose #4. In all cities, the effect of body mass index (BMI) on body satisfaction was highly significant (p < 0.001). Almost 40% of the middle weight adolescents indicated a preference to be thinner, even though 72% of the males and 84% of the females in this subgroup already perceived themselves as thin. Similarly, 89% of the heavier weight participants indicated a preference to be thinner, even though only 10% of the males and 2% of the females in this subgroup perceived themselves as heavy. In five of the six cities, a significantly higher (p < 0.05) percentage of females than males desired to be thinner, the exception being Havana, where the distribution of desired change in body size was almost identical for males and females. Findings suggest a need for culturally sensitive, age- and gender-specific preventive interventions focusing on the importance of achieving a

    The current study aimed to situate the development of adolescent narrative identity in the context of past-event conversations between adolescents and their mothers, extending work on conversational contexts in early childhood to adolescence. We examined a cross-section of 63 adolescents with 2 goals: (1) to examine how adolescent age and gender interacted with mothers' scaffolding behaviors and how those interactions were associated with adolescents' narrative processes of meaning-making, vulnerability, and resolution; (2) to examine mothers' behaviors in conversation and how the interactions between those behaviors and event type (important, sad, and happy themes) were associated with those narrative processes. We found that maternal behavior in the conversation was related to adolescent narrative processes, yet this link varied as a function of characteristics of the adolescent and type of event discussed. Overall results suggest that those with potentially less practice at narrating the self in elaborative ways--younger adolescents and boys--receive more supportive scaffolding, and that for those with likely more practice with elaborative narration--girls and older adolescents--mothers engage in more negation behavior. The role of these scaffolding behaviors in adolescent narrative identity development is discussed.

    We hypothesized that longer and more frequent dosing gaps among boys in Botswana taking antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection compared to girls could account for previously seen gender-specific differences in outcomes. We monitored 154 male and 134 female adolescents for 2 years with medication event monitoring systems (MEMS). Median adherence was 95.6 % for males and 95.7 % for females (p = 0.40). There were no significant gender differences in the number of ≥7 day (p = 0.55) and ≥14 day (p = 0.48) dosing gaps. The median maximal gap was 7.7 days for males and 8.0 days for females (p = 0.47). These findings are not consistent with clinically meaningful gender differences in adherence.

    This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=−0.19; p<0.01) and that higher body mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=−0.17, p<0.01) only in non-practitioners. The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η2=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η2=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group. PMID:25713641

    Adolescent pregnancy has social, economic, and educational consequences and is also linked to adverse perinatal outcomes. However, studies show a positive relationship between pregnancy and increased social status among low-income adolescents. This study aims to assess the association between planned pregnancy and years of schooling among low-income Brazilian adolescents. This is a secondary analysis of a cohort study conducted from May 2005 to March 2007 in public primary care clinics in São Paulo, Brazil. Participants (n=168) completed a detailed structured questionnaire. Logistic regression was used to examine the association between years of schooling and planned pregnancy. After adjusting for the covariates income, wealth score, crowding, age, marital status, and race, planned pregnancy was independently associated with lower years of education (odds ratio: 1.82; 95% confidence interval: 1.02–3.23). Although this finding may be related to these adolescents having less access to information and health services, another possible explanation is that they have a greater desire to have children during adolescence.

    Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis has been implicated in the induction and prolongation of a variety of psychiatric disorders. As such, much effort has been made to understand the molecular mechanisms involved in its control. However, the vast majority of the studies on the HPA axis have used adult animals, and among these the majority has used males. Here we show that in knockout mice lacking the guanine nucleotide exchange factor, RasGRF1, habituation to 30 minutes a day of restraint stress is markedly accelerated, such that these mice do not display elevated corticosterone levels or enhanced locomotion after 7 days of stress exposure, like WT mice do. Strikingly, this phenotype is present in early-adolescent female RasGRF1 knockout mice, but not in their early-adolescent male, mid-adolescent female, adult female or adult male counterparts. Moreover, not only is there a clear response to restraint stress in early-adolescent female RasGRF1 knockout mice, their response after 1, 3, and 5 exposures is magnified ~3-fold compared to WT mice. These findings imply that distinct mechanisms exist to regulate the HPA axis in early-adolescent females that involves RasGRF1. A full understanding of how RasGRF1 controls the HPA axis response to stress may be required to design effective strategies to combat stress-associated psychiatric disorders initiated in young females.

    Objective Adolescents living with HIV are sexually active and engaged in risky sexual behaviors. Knowledge on how and to what extent adolescents in HIV care are affected by pregnancy is needed so as to adopt better preventive services. We estimated 4-year pregnancy incidence and correlates among HIV-infected female adolescents in HIV care in urban Côte d'Ivoire. Design We conducted retrospective analysis of a pediatric prospective cohort of the International epidemiological Databases to Evaluate AIDS (IeDEA) West Africa Collaboration. Female patients with confirmed HIV infection aged 10–19 years, having at least one clinical visit in 2009 to health facilities participating in the pediatric IeDEA West African cohort in Abidjan, Côte d'Ivoire, were included. Data on incident pregnancies were obtained through medical records and interviews with health professionals. Pregnancy incidence rate was estimated per 100 person-years (PY). Poisson regression models were used to identify factors associated with the first pregnancy and provided incidence rate ratios (IRR) with 95% confidence intervals (CI). Results In 2009, 266 female adolescents were included, with a median age of 12.8 years (interquartile range, IQR: 10.0–15.0), CD4 cell counts of 506 cells/mm3 (IQR: 302–737), and 80% on antiretroviral treatment. At the 48th month, 17 new pregnancies were reported after 938 PY of follow-up: 13 girls had one pregnancy while 2 had two pregnancies. Overall incidence rate of pregnancy was 1.8/100 PY (95% CI: 1.1–2.9). High incidence was observed among those aged 15–19 years: 3.6/100 PY (95% CI: 2.2–5.9). Role of maternal death in the risk of pregnancy was at the limit of statistical significance (adjusted IRR: 3.1, 95% CI: 0.9–11.0; ref. non-maternal orphans). Conclusions Incidence of pregnancy among HIV-infected adolescents in care aged 15–19 years reached a level observed in adult cohorts in Sub-Saharan Africa. Health personnel in pediatric care have to

    Childhood sexual abuse (CSA) is associated with multiple negative outcomes, including increased risky sexual behavior. To date, the majority of research on the relationship between CSA and risky sex in adolescence has been limited, with a lack of focus on males and youth receiving child welfare services. Participants in the current study were 297 youth (mean age=15.98; SD=1.01, 57.6% female) from the child welfare system who reported being sexually active at the time of the survey. CSA was associated with severity of other types of maltreatment for both genders, and exposure to intimate partner violence for females only. In general, males engaged in more sexual risk behaviors than females. Males with CSA had stronger motives to have sex for: (1) coping, (2) peer approval and (3) partner approval, as compared to non-CSA males; as well as (4) greater motives for partner and peer approval compared to females with CSA. Males with no CSA had stronger sexual motives for enhancement (e.g., feeling pleasure) compared to females with no CSA. Mediation analyses revealed a significant indirect effect for coping motives for males: CSA was associated with increased motives to use sex for coping which was associated with increased sexual risk-taking. These findings provide important information regarding the relationship between CSA and sexual risk-taking for child welfare sample and highlight coping with negative affect as a potential mechanism that underlies the CSA-risky sex relationship. It also encourages further consideration of motives for risk and resilience behaviors among youth.

    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. PMID:21713113

    This article discusses one of the emergent themes of a qualitative research carried out with female adolescents in the neighborhood of Acaba Mundo, in the city of Belo Horizonte, State of Minas Gerais, and aims at understanding their social representations on sexual initiation concerning gender. The data was collected in four workshops and analyzed on the basis of the social representation theory by means of the discourse analysis technique. Two empirical categories and their consequences emerged from the discourse: leaving childhood behind and fear of pregnancy. The understanding of the social representations and of the gender relationships made the values, ideas and practices of the adolescents and their family clear. It also made clear that those values, ideas and practices were in frequent transformation in the social field.

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

    The occurrence of mate solicitation by virgin females was investigated in the butterfly Euremahecabe. Young (1-day-old) virgin females rarely showed mate solicitation to male model, however, old (at least 6-day-old) virgin females frequently showed such flight. The duration of solicitation was significantly longer in older females than in younger ones. The age-related behavioral change occurs with female oogenesis (Hiroki and Kato 1996), and such behavior may thus be a result of female adaptation to maximize their fecundity.

    Methylphenidate (MPD), or Ritalin, is a psychostimulant that is prescribed for an extended period of time to children and adolescents with attention deficit hyperactivity disorder. Adolescence is a time of critical brain maturation and development, and the drug exposure during this time could lead to lasting changes in the brain that endure into the adulthood. Circadian rhythms are 24 h rhythms of physiological processes that are synchronized by the master-clock, the suprachiasmatic nucleus, to keep the body stable in a changing environment. The aim of present study is to observe the effect of repeated MPD exposure on the locomotor diurnal rhythm activity patterns of female adolescent Sprague-Dawley (SD) rats using the open field assay. 31 female adolescent SD rats were divided into four groups: control, 0.6 mg/kg, 2.5 mg/kg, and 10 mg/kg MPD group. On experimental day 1, all groups were given an injection of saline. On experimental days 2-7, animals were injected once a day with either saline, 0.6 mg/kg, 2.5 mg/kg, or 10 mg/kg MPD, and experimental days 8-10 were the washout period. A re-challenge injection was given to each animal on experimental day 11 with the similar dose as the experimental days 2-7. The locomotor movements were counted by the computerized animal activity monitoring system. The data were analyzed statistically to find out whether the diurnal rhythm activity patterns were altered. The obtained data showed that repeated administrations of 2.5 mg/kg and 10 mg/kg MPD were able to change the locomotor diurnal rhythm patterns, which suggests that these MPD doses exerts long-term effects.

  7. The evolution of alternative cryptic female choice strategies in age-structured populations.

    PubMed

    Jones, Adam G

    2002-12-01

    Cryptic female choice is a potentially important aspect of the sexual selection process. According to the theory of sexual dialectics, postcopulation manipulation of relative male fertilization success can provide an avenue by which females can circumvent attempts by males to control female reproduction. Here I use stochastic models to investigate the evolution of cryptic female choice in populations with and without age structure. In populations without age structure, cryptic female choice will evolve only when (1) precopulatory mate choice by females is inefficient, (2) variation in male fitness is correlated with a trait upon which a female can base her choice of mates, and (3) the cost of multiple mating is not too high. In populations with age structure, similar conditions apply. However, selection sometimes favors females that employ alternative strategies of female choice at different ages. These results help to define the types of biological systems in which we should expect to see the evolution of cryptic female choice. They also illustrate that the evolution of choice strategies in females may be complex and may mirror in some important respects the evolution of alternative mating tactics in males.

    We assessed relations between early temperament and behavior problems across 12 years in an unselected sample of over 800 children. Temperament measures were drawn from behavior ratings made by examiners who observed children at ages 3, 5, 7, and 9. Factor analyses revealed 3 dimensions at each age: Lack of Control, Approach, and Sluggishness. Temperament dimensions at ages 3 and 5 were correlated in theoretically coherent ways with behavior problems that were independently evaluated by parents and teachers at ages 9 and 11, and by parents at ages 13 and 15. Lack of Control was more strongly associated with later externalizing behavior problems than with internalizing problems; Approach was associated with fewer internalizing problems among boys; and Sluggishness was weakly associated with both anxiety and inattention, especially among girls. Lack of Control and Sluggishness were also associated with fewer adolescent competencies. These results suggest that early temperament may have predictive specificity for the development of later psychopathology.

    Psychosocial stress, including stress resulting from racial discrimination (RD), has been associated with elevated depressive symptoms. However, individuals vary in their reactivity to stress, with some variability resulting from genetic differences. Specifically, genetic variation within the linked promoter region of the serotonin transporter gene (5-HTTLPR) is related to heightened reactivity to emotional environmental cues. Likewise, variations within this region may interact with stressful life events (e.g., discrimination) to influence depressive symptoms, but this has not been empirically examined in prior studies. The objective of this study was to examine whether variation in the 5-HTTLPR gene interacts with RD to predict depressive symptoms among a sample of African–American adolescent females. Participants were 304 African–American adolescent females enrolled in a sexually transmitted disease prevention trial. Participants completed a baseline survey assessing psychosocial factors including RD (low vs. high) and depressive symptomatology (low vs. high) and provided a saliva sample for genotyping the risk polymorphism 5-HTTLPR (s allele present vs. not present). In a logistic regression model adjusting for psychosocial correlates of depressive symptoms, an interaction between RD and 5-HTTLPR group was significantly associated with depressive symptomatology (AOR = 3.79, 95% CI: 1.20–11.98, p = 0.02). Follow-up tests found that high RD was significantly associated with greater odds of high depressive symptoms only for participants with the s allele. RD and 5-HTTLPR status interact to differentially impact depressive symptoms among African–American adolescent females. Efforts to decrease depression among minority youth should include interventions which address RD and strengthen factors (e.g., coping, emotion regulation, building support systems) which protect youth from the psychological costs of discrimination.

    Background Social anxiety is one of the most common psychological disorders that exists among children and adolescents, and it has profound effects on their psychological states and academic achievements. Objectives The aim of this study was to determine the effectiveness of mindfulness-based cognitive therapy (MBCT) on diminishing social anxiety disorder symptoms and improving the self-esteem of female adolescents suffering from social anxiety. Patients and Methods Semi-experimental research was conducted on 30 female students diagnosed with social anxiety. From the population of female students who were studying in Tehran’s high schools in the academic year of 2013 - 2014, 30 students fulfilling the DSM-5 criteria were selected using the convenience sampling method and were randomly assigned to control and experimental groups. The experimental group received eight sessions of MBCT treatment. The control group received no treatment. All participants completed the social phobia inventory (SPIN) and Rosenberg self-esteem scale (RSES) twice as pre- and post-treatment tests. Results The results from the experimental group indicated a statistically reliable difference between the mean scores from SPIN (t (11) = 5.246, P = 0.000) and RSES (t (11) = -2.326, P = 0.040) pre-treatment and post-treatment. On the other hand, the results of the control group failed to reveal a statistically reliable difference between the mean scores from SPIN (t (12) = 1.089, P = 0.297) and RSES pre-treatment and post-treatment (t (12) = 1.089, P = 0.000). Conclusions The results indicate that MBCT is effective on both the improvement of self-esteem and the decrease of social anxiety. The results are in accordance with prior studies performed on adolescents. PMID:28191335

    The influence of female age on male mating preference and reproductive success has been studied using a promiscuous cabbage beetle, Colaphellus bowringi Baly (Coleoptera: Chrysomelidae). In a simultaneous choice test, middle-aged females had significantly greater mating success than young and old females. In single pair trials, when paired with middle-aged virgin males, middle-aged females mated faster, copulated longer, and had greater fecundity and fertility than young or old females, while the longevity of males was not significantly affected by female age. This study on C. bowringi suggests that middle-aged females are more receptive to mating, which can result in the highest male reproductive success.

    INTRODUCTION Fertility in women declines with increasing age. With the deferment of marriage and childbearing, couples are turning to assisted reproductive technology to counteract this decline. We aimed to evaluate the results of in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) in women of different age groups, and highlight the cost-effectiveness of IVF treatment in these groups while assessing its implications on the national healthcare provision model. METHODS Retrospective analysis of 3,412 stimulated IVF/ICSI cycles in a hospital-based IVF centre was performed from January 2008 to December 2010. Patients were stratified into seven age groups: < 30 years; 30–35 years; 36–37 years; 38 years; 39 years; 40–44 years; and ≥ 45 years. RESULTS Age had a significant effect on the number of cycles leading to embryo transfer (p < 0.001). The number of oocytes retrieved decreased across the various age groups (p < 0.001) and was the highest among women aged < 30 (mean 18.5 ± 10.3) years. With increasing age, there was a trend toward a lower fertilisation rate. Age also had a significant effect on the rates of clinical pregnancy, live birth and multiple pregnancies (p < 0.001). CONCLUSION Patients aged < 30 years had the best IVF outcomes, reflecting optimal reproductive capacity. Age-related decline in fertility starts after 30 years. Women opting for IVF should be counselled about age-specific success rates while taking into account individual risk factors. PMID:25017405

    Background: Nemaline rod disease is a congenital myopathy, presentation of which may mimic myasthenia gravis. Method: We report a suspected case of nemaline rod disease in a female adolescent who presented with features similar to myasthenia gravis but failed to respond effectively to its conventional management. She had features of respiratory failure and cardiomyopathy. Results: Patient had a turbulent clinical course and finally succumbed to illness on the fifth day of admission. Conclusion: This report is meant to sensitize child neurologists and general paediatricians on the need to have a broad spectrum of considerations in the management of suspected myasthenia gravis, especially when response to anticholinesterase is poor.

  15. Survival of female Lesser Scaup: Effects of body size, age, and reproductive effort

    In birds, larger females generally have greater breeding propensity, reproductive investment, and success than do smaller females. However, optimal female body size also depends on how natural selection acts during other parts of the life cycle. Larger female Lesser Scaup (Aythya affinis) produce larger eggs than do smaller females, and ducklings from larger eggs survive better than those hatching from smaller eggs. Accordingly, we examined patterns of apparent annual survival for female scaup and tested whether natural selection on female body size primarily was stabilizing, a frequent assumption in studies of sexually dimorphic species in which males are the larger sex, or was directional, counter-acting reproductive advantages of large size. We estimated survival using mark-recapture methods for individually marked females from two study sites in Canada (Erickson, Manitoba; St. Denis, Saskatchewan). Structurally larger (adults) and heavier (ducklings) females had lower survival than did smaller individuals in Manitoba; no relationship was detected in adults from Saskatchewan. Survival of adult females declined with indices of increasing reproductive effort at both sites; consequently, the cost of reproduction could explain age-related patterns of breeding propensity in scaup. Furthermore, if larger females are more likely to breed than are smaller females, then cost of reproduction also may help explain why survival was lower for larger females. Overall, we found that advantages of large body size of female scaup during breeding or as young ducklings apparently were counteracted by natural selection favoring lightweight juveniles and structurally smaller adult females through higher annual survival.

    A central tenet of evolutionary explanations for ageing is that the strength of selection wanes with age. However, data on age-specific expression and benefits of sexually selected traits are lacking—particularly for traits subject to sexual conflict. We addressed this by using as a model the responses of Drosophila melanogaster females of different ages to receipt of sex peptide (SP), a seminal fluid protein transferred with sperm during mating. SP can mediate sexual conflict, benefitting males while causing fitness costs in females. Virgin and mated females of all ages showed significantly reduced receptivity in response to SP. However, only young virgin females also showed increased egg laying; hence, there was a narrow demographic window of maximal responses to SP. Males gained significant ‘per mating’ fitness benefits only when mating with young females. The pattern completely reversed in matings with older females, where SP transfer was costly. The overall benefits of SP transfer (hence opportunity for selection) therefore reversed with female age. The data reveal a new example of demographic variation in the strength of selection, with convergence and conflicts of interest between males and ageing females occurring over different facets of responses to a sexually antagonistic trait.

    It was reported in 1980s that ages at which peak performance was observed had remained remarkably stable in the past century, although absolute levels of athletic performance increased dramatically for the same time span. The emergence of older (masters) athletes in the past few decades has changed the demographics and age-spectrum of Olympic athletes. The primary aim of the present study was to determine whether the ages at which peak performance was observed had increased in the recent decades. The data spanning 114 years from the first Olympics (1898) to the most recent Olympics (2014) were collected using the publically available data. In the present study, ages at which Olympic medals (gold, silver, and bronze) were won were used as the indicators of peak performance age. Track and field, swimming, rowing, and ice skating events were analyzed. In men, peak performance age did not change significantly in most of the sporting events (except in 100 m sprint running). In contrast, peak performance ages in women have increased significantly since 1980s and consistently in all the athletic events examined. Interestingly, as women's peak performance age increased, they became similar to men's peak ages in many events. In the last 20-30 years, ages at which peak athletic performance is observed have increased in women but not in men.

    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

    Body composition and sport participation have been associated with bone mass. The purpose of this study was to determine the associations of lean and fat mass measures with whole body bone mineral content (BMC) and bone mineral density (BMD) in female adolescent weightlifters, swimmers and non-athletic counterparts. This study included a total of 25 female adolescents (mean age: 15.3±1.1 years). Body composition and bone mass were measured by dual-energy X-ray absorptiometry. In most of the studied variables weight lifters had higher values compared to swimmers and non-athletes (p < 0.05). No significant difference was observed between swimmers and non-athletes (p > 0.05). Lean and fat mass measures were positively associated with BMC and BMD for the total participants (p < 0.05) while the associations differed when the study groups were analysed separately. In conclusion, both lean and fat mass measures were strongly related to BMC and BMD in female adolescents while these associations differed in swimmers, weightlifters and non-athletes.

    2010-03-05

    This report presents a case of a displaced stress fracture of the femoral neck in an adolescent female distance runner with amenorrhea. Both reduction and internal fixation were performed early after the injury. At 24 months postoperatively, magnetic resonance imaging and bone scintigraphy showed no positive signs of femoral head necrosis and bone union was confirmed on plain X-ray. A medical examination for the presence of the signs of the female athlete triad by checking weight, calorie intake and menstrual cycles is most important to prevent such stress fractures. Athletes as well as their coaches or parents therefore need to understand female athlete triad.

    Tubo-ovarian abscess (TOA) in non-sexually active female adolescents is a rare presentation to the pediatric emergency department. In the following case, bilateral TOA secondary to Streptococcus constellatus was diagnosed in a 13-year-old virginal female. The patient was seen 4 months before presentation for interventional radiology-guided drainage and antibiotic treatment for an intra-abdominal abscess due to suspected appendiceal rupture. Exploratory laparotomy on the most recent presentation demonstrated an appendix with inflammation and serositis on pathology report, a concern for chronic appendicitis with microperforation and subsequent bacterial translocation of the bilateral ovaries. This case report identifies a rare cause, pathogen, and the patient's demographics presenting with bilateral TOA. Most importantly, this case demonstrates the need for emergency medicine physicians to have a high index of suspicion for TOA in patients with a significant medical history of intra-abdominal pathology to promptly diagnose and treat high-morbidity pathology.

    This study investigated the prevalence of disordered eating cognitions and behaviours across mid-adolescence in a large European sample, and explored the extent to which prevalence ratings were affected by informant (parent/adolescent), or the sex or age of the adolescent. The Development and Well-Being Assessment was completed by parent-adolescent dyads at age 14 (n = 2225) and again at age 16 (n = 1607) to explore the prevalence of 7 eating disorder symptoms (binge eating, purging, fear of weight gain, distress over shape/weight, avoidance of fattening foods, food restriction, and exercise for weight loss). Informant agreement was assessed using kappa coefficients. Generalised estimating equations were performed to explore the impact of age, sex and informant on symptom prevalence. Slight to fair agreement was observed between parent and adolescent reports (kappa estimates between 0.045 and 0.318); however, this was largely driven by agreement on the absence of behaviours. Disordered eating behaviours were more consistently endorsed amongst girls compared to boys (odds ratios: 2.96-5.90) and by adolescents compared to their parents (odds ratios: 2.71-9.05). Our data are consistent with previous findings in epidemiological studies. The findings suggest that sex-related differences in the prevalence of disordered eating behaviour are established by mid-adolescence. The greater prevalence rates obtained from adolescent compared to parent reports may be due to the secretive nature of the behaviours and/or lack of awareness by parents. If adolescent reports are overlooked, the disordered behaviour may have a greater opportunity to become more entrenched.

    Reward/behavioral approach system hypersensitivity is implicated in bipolar disorders (BD) and in normative development during adolescence. Pediatric onset of BD is associated with a more severe illness course. However, little is known about neural processing of rewards in adolescents with BD or developmental (i.e., age) associations with activation of these neural systems. The present study aims to address this knowledge gap. The present sample included 21 adolescents with BD and 26 healthy adolescents, ages 13 to 19. Participants completed a functional magnetic resonance imaging (fMRI) protocol using the Monetary Incentive Delay (MID) task. Behavioral performance was similar between groups. Group differences in BOLD activation during target anticipation and feedback anticipation periods of the task were examined using whole-brain analyses, as were group differences in age effects. During both target anticipation and feedback anticipation, adolescents with BD, compared to adolescents without psychopathology, exhibited decreased engagement of frontal regions involved in cognitive control (i.e., dorsolateral prefrontal cortex). Healthy adolescents exhibited age-related decreases, while adolescents with BD exhibited age-related increases, in activity of other cognitive control frontal areas (i.e., right inferior frontal gyrus), suggesting altered development in the BD group. Longitudinal research is needed to examine potentially abnormal development of cognitive control during reward pursuit in adolescent BD and whether early therapeutic interventions can prevent these potential deviations from normative development.

    High rates of posttraumatic stress disorder (PTSD) symptoms and elevated levels of aggression are common among youth in inpatient psychiatric settings. Several models link trauma exposure to aggression through anomalous mental state reasoning. Some theoretical frameworks linking trauma to aggression specify that the over-attribution of hostile mental states contributes to the development of aggressive behavior whereas other theories suggest that an inhibition of mental state reasoning leads to aggressive behavior. Using a sample of inpatient adolescents, the current study examined relations between PTSD symptoms and four forms of aggression, exploring the role of both over- and under-mentalizing (i.e., hypo- and hypermentalizing) as mediators and gender as a moderator. The results suggest that hypermentalizing, but not hypomentalizing, mediates the relation between trauma and aggression, extending prior research related to inpatient adolescents for the first time. Evidence of moderated mediation was noted, such that this mediational relation was evident for females but not males. The current study offers support for differential underlying causes of aggression among males and females with PTSD symptoms.

    Eucommia ulmoides is one of the popular tonic herbs for the treatment of low back pain and bone fracture and is used in Korean medicine to reinforce muscles and bones. This study was performed to investigate the effects of E. ulmoides extract on longitudinal bone growth rate, growth plate height, and the expressions of bone morphogenetic protein 2 (BMP-2) and insulin-like growth factor 1 (IGF-1) in adolescent female rats. In two groups, we administered a twice-daily dosage of E. ulmoides extract (at 30 and 100 mg/kg, respectively) per os over 4 days, and in a control group, we administered vehicle only under the same conditions. Longitudinal bone growth rate in newly synthesized bone was observed using tetracycline labeling. Chondrocyte proliferation in the growth plate was observed using cresyl violet dye. In addition, we analyzed the expressions of BMP-2 and IGF-1 using immunohistochemistry. Eucommia ulmoides extract significantly increased longitudinal bone growth rate and growth plate height in adolescent female rats. In the immunohistochemical study, E. ulmoides markedly increased BMP-2 and IGF-1 expressions in the proliferative and hypertrophic zones. In conclusion, E. ulmoides increased longitudinal bone growth rate by promoting chondrogenesis in the growth plate and the levels of BMP-2 and IGF-1. Eucommia ulmoides could be helpful for increasing bone growth in children who have growth retardation.

    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.

    The psychostimulants considered the gold standard in the treatment of attention deficit hyperactivity disorder, one of the most common childhood disorders, are also finding their way into the hands of healthy young adults as brain augmentation to improve cognitive performance. The possible long-term effects of psychostimulant exposure in adolescence are considered controversial, and thus, the objective of this study was to investigate whether the chronic exposure to the psychostimulant amphetamine affects the behavioral diurnal rhythm activity patterns of female adolescent Wistar-Kyoto (WKY) rat. The hypothesis of this study is that change in diurnal rhythm activity pattern is an indicator for the long-term effect of the treatment. Twenty-four rats were divided into two groups, control (N = 12) and experimental (N = 12), and kept in a 12:12-h light/dark cycle in an open-field cage. After 5-7 days of acclimation, 11 days of consecutive non-stop behavioral recordings began. On experimental day 1 (ED1), all groups were given an injection of saline. On ED2 to ED7, the experimental group was injected with 0.6 mg/kg amphetamine followed by 3 days of washout from ED8 to ED10, and amphetamine re-challenge on ED11 similar to ED2. The locomotor movements were counted by the computerized animal activity monitoring system, and the cosinor statistical test analysis was used to fit a 24-h curve of the control recording to the activity pattern after treatment. The horizontal activity, total distance, number of stereotypy, vertical activity, and stereotypical movements were analyzed to find out whether the diurnal rhythm activity patterns were altered. Data obtained using these locomotor indices of diurnal rhythm activity pattern suggest that amphetamine treatment significantly modulates the locomotor diurnal rhythm activity pattern of female WKY adolescent rats.

    Background Population-based studies for prevalence of metabolic syndrome (M.S) in children and adolescents are relatively rare. The aim of this study was to assess the Prevalence of M.S and correlated factors among children and adolescents aged 10 to 19 years in Ahvaz. Methods In this descriptive-analytical population- based study, 2246 children and adolescents, 10–19 years old (1113 male and 1133 female) in Ahvaz, were evaluated. Anthropometry, biochemical measurement and blood pressure (BP) were assessed. Modified ATP III criteria 2005 were used for M.S. definition. Center for disease and Control preventions (CDC) percentile were applied to define cut off points of waist circumference and BP. Results Prevalence of M.S. was 9% (95% CI: 8-10%) with prevalence in male 11% (95% CI: 10-12%) and female 7% (95% CI 6-8%). Among individuals with M.S, triglyceride (TG) and decreased high density lipoprotein (HDL) cholesterol levels were the most common components (33.5% and 24.1%, respectively). Prevalence of M.S was higher in overweight persons comparing to participants with at risk and normal weight group (in male: 24.1%, 14.3% and 9.9% respectively P = 0.0001), (in female: 22.6%, 18.3% and 4.5% respectively P = 0.0001). Among the correlated factors of M.S age (P = 0.0006), sex and BMI (P = 0.0001) had significant differences between subjects with and without M.S. whereas there was no significant difference between two groups in ethnicity, history of breast fed, birth weight neonatal ICU admission, maternal history(GDM, gestational HTN, Parity) and family history of HTN, obesity and DM (P > 0.05). Conclusion This study shows high prevalence of M.S in Children and Adolescents in south west of Iran (Ahvaz) especially in overweight persons. PMID:24860794

    Background Many observational studies have shown a protective effect of physical activity on cognitive ageing, but interventional studies have been less convincing. This may be due to short time scales of interventions, suboptimal interventional regimes or lack of lasting effect. Confounding through common genetic and developmental causes is also possible. Objectives We aimed to test whether muscle fitness (measured by leg power) could predict cognitive change in a healthy older population over a 10-year time interval, how this performed alongside other predictors of cognitive ageing, and whether this effect was confounded by factors shared by twins. In addition, we investigated whether differences in leg power were predictive of differences in brain structure and function after 12 years of follow-up in identical twin pairs. Methods A total of 324 healthy female twins (average age at baseline 55, range 43-73) performed the Cambridge Neuropsychological Test Automated Battery (CANTAB) at two time points 10 years apart. Linear regression modelling was used to assess the relationships between baseline leg power, physical activity and subsequent cognitive change, adjusting comprehensively for baseline covariates (including heart disease, diabetes, blood pressure, fasting blood glucose, lipids, diet, body habitus, smoking and alcohol habits, reading IQ, socioeconomic status and birthweight). A discordant twin approach was used to adjust for factors shared by twins. A subset of monozygotic pairs then underwent magnetic resonance imaging. The relationship between muscle fitness and brain structure and function was assessed using linear regression modelling and paired t tests. Results A striking protective relationship was found between muscle fitness (leg power) and both 10-year cognitive change [fully adjusted model standardised β-coefficient (Stdβ) = 0.174, p = 0.002] and subsequent total grey matter (Stdβ = 0.362, p = 0.005). These effects were robust in discordant

    Prescription opiate use by adolescent girls has increased significantly in the past decade. Preclinical studies using rats report alterations in morphine sensitivity in the adult offspring of adolescent morphine-exposed females (MOR-F1) when compared with the offspring of adolescent saline-exposed females (SAL-F1). To begin to elucidate the development of these next generation modifications, the present study examined the effects of acute morphine administration on sedation and corticosterone secretion in prepubescent SAL-F1 and MOR-F1 male and female rats. In addition, alterations in proopiomelanocortin (POMC) gene expression in the arcuate nucleus, as well as in tyrosine hydroxylase (TH) and μ-opioid receptor (OPRM1) gene expressions in the ventral tegmental area, were analyzed using quantitative PCR, to determine whether differential regulation of these genes was correlated with the observed behavioral and/or endocrine effects. Increased morphine-induced sedation, coupled with an attenuation of morphine-induced corticosterone secretion, was observed in MOR-F1 males. Significant alterations in both POMC and OPRM1 gene expressions were also observed in MOR-F1 males, with no change in TH mRNA expression. Overall, these data suggest that the transgenerational effects of adolescent morphine exposure can be discerned before pubertal development and are more pronounced in males, and suggest dysregulation of the hypothalamic-pituitary-adrenal axis in the offspring of adolescent morphine-exposed females.

    The link between obesity and self-esteem among minority youth has received minimal empirical evaluation. This study aims to describe the magnitude of risk that body mass index, household income, and transitional age have on global self-esteem levels among African-American adolescents. These analyses were conducted on cross-sectional data obtained from 264 urban-dwelling African-American females between 14 and 18 years of age. Survey data on global self-esteem levels, transitory age, and socioeconomic levels were collected using self-administered questionnaires. Measured height and weight values were used to calculate and categorize weight status according to body mass index. Logistic regression models examined the probability of reporting less than average levels of global self-esteem. Adolescent African-American females residing in low-income households were 10 times more likely to report lower global self-esteem scores than those individuals from more affluent households (95% CI: 1.94, 60.19, p < .001). Neither weight status (95% CI: 0.81, 2.55; p = .26) nor age (95% CI: 0.05, 1.87; p = .82) were significant risk indicators for lower than average levels of global self-esteem among participants in this study. Household income appears to be the greatest predictor of global self-esteem levels. Further research in this area is needed to fully elucidate precursors for psychological health vulnerability and facilitate intervention development.

    Aim The aim of this study was to investigate long-term cognitive outcome in a cohort of 18-year-olds born preterm and previously assessed at the age of 5.5. Methods We tested 134 adolescents born preterm with a very low birthweight of <1500 g and 94 term-born controls with a comprehensive cognitive battery at 18 years of age. The cohort was subdivided into 73 extremely preterm, 42 very preterm and 19 moderately preterm infants with gestational ages of 23–27, 28–31 and 32–36 weeks, respectively. The moderately preterm group was dominated by adolescents born small for gestational age. Results Very preterm adolescents performed on a par with term-born controls. In contrast, extremely preterm adolescents displayed inferior results on all cognitive tests, more so if they had suffered neonatal complications. Moderately preterm adolescents scored lower than very preterm and full-term born adolescents, particularly on complex cognitive tasks. Conclusion Adolescents born at 28 weeks of gestation or later, with appropriate birthweight and no perinatal complications, functioned like term-born peers at 18 years of age. Extremely preterm birth per se posed a risk for long-term cognitive deficits, particularly executive deficits. Adolescents born moderately preterm but small for gestational age were at risk of general cognitive deficits. PMID:25394225

    Adopting a multi-level approach, this study examined risk factors for adolescent suicidal ideation, with specific attention to (a) hypothalamic-pituitary-adrenal (HPA) axis stress responses and (b) the interplay between HPA-axis and other risk factors from multiple domains (i.e., psychological, interpersonal and biological). Participants were 138 adolescent females (M(age) = 14.13 years, SD = 1.40) at risk for suicidal behaviors. At baseline, lifetime suicidal ideation and a number of risk factors were assessed (i.e., depressive symptoms, impulsiveness, pubertal status and peer stress). Participants were exposed to a psychosocial stress task and HPA-axis responses were assessed by measuring cortisol levels pre- and post-stressor. At 3 months post-baseline, suicidal ideation again was assessed. Using group-based trajectory modeling, three groups of cortisol stress-response patterns were identified (i.e., hyporesponsive, normative, and hyperresponsive). As compared to females in the normative and hyporesponsive group, females in the hyperresponsive group were more likely to report a lifetime history of suicidal ideation at baseline, above and beyond the effects of the other predictors. Moreover, as compared to females in the normative group, females in the hyperresponsive group were at increased risk for reporting suicidal ideation 3 months later, after controlling for prior ideation. No interactions between cortisol group and the other risk factors were significant, with the exception of a non-significant trend between impulsiveness and cortisol group on lifetime suicidal ideation. Findings highlight the importance of HPA-axis responses to acute stressors as a risk factor for suicidal ideation among adolescents.

    Cancer represents the second cause of death in prepubertal children and adolescents, although it is currently associated with an overall survival rate of 80%–85%. The annual incidence rate is 186.6 per 1 million children and adolescents aged up to 19 years. Both disease and treatment options are associated with life-altering, long-term effects that require monitoring. Infertility is a common issue, and as such, fertility preservation represents an essential part in the management of young patients with cancer who are at risk of premature gonadal failure. This review deals with the up-to-date available data on fertility risk assessment and preservation strategies that should be addressed prior to antineoplastic therapy in this vulnerable subgroup of cancer patients.

    Objective Although research has found an inverse correlation between physical activity and depression among adolescents, few studies have examined this relation prospectively. Thus, we tested whether physical activity reduces risk for future escalations in depression and whether depression decreases likelihood of future change in physical activity. Method Data from a longitudinal study involving annual assessments of 496 adolescent girls (M age = 13, SD 0.7) followed over a 6-year period were analyzed to address these questions. Results Physical activity significantly reduced risk for future increases in depressive symptoms and risk for onset of major/minor depression and depressive symptoms and major/minor depression significantly reduced future physical activity, controlling for several covariates, though predictive effects were modest. Conclusions Results support a bidirectional relation between exercise and depression and imply that interventions that increase physical activity may reduce risk for depression among this high-risk population.

    Nocturnal concentrations of melatonin in serum decline significantly with advancing pubertal development in both children and non-human primates and elevated levels may be associated with anovulation in adults. Three studies, using female rhesus monkeys, were performed to determine whether (1) the decline in nocturnal melatonin concentrations in adolescents was due to maturational increases in serum oestradiol, (2) the experimental elevation in nocturnal melatonin would delay the normal progression of puberty in post-menarchial monkeys, and (3) the experimental elevation in nocturnal melatonin would disrupt normal ovulatory function in adults. In experiment 1, juvenile female rhesus monkeys, housed indoors in a fixed photoperiod (12 h light:12 h darkness), were assigned randomly to one of two treatment groups: ovariectomized with no replacement therapy (control; n = 4) or ovariectomized with oestradiol replacement therapy maintaining oestradiol at approximately 90 pmol/l (treated; n = 8). Twenty-four hour as well as daytime serum samples were collected from 19 to 35 months of age. Nocturnal melatonin concentrations declined significantly in all females with advancing chronological age and this change was unaffected by oestradiol treatment. The decline in nocturnal melatonin concentrations occurred, on average, 2.0 +/- 0.2 months after the initial rise in serum LH in control females and 6.0 +/- 0.8 months in treated females. Furthermore, this decline in night-time melatonin was not related to significant developmental changes in body weight. In experiment 2, control (n = 6) and melatonin-treated (treated; n = 6) adolescent female monkeys were studied from -30 to +105 days from menarche. Beginning at 45 days following menarche, treated females received 30 days of nocturnal melatonin infusion to elevate levels to prepubertal values. Developmental changes in perineal swelling and coloration as well as serum oestradiol and insulin-like growth factor-I (IGF-I) were

    Purpose This study examined the relationships between early menarche and sexual behaviors among Korean female adolescents. Methods We analyzed data from the eighth Korea Youth Risk Behavior Web-based survey that was conducted on female high school students in grades 10-12. The survey included 17,867 students, and 974 students were assigned to the early menarche group because they had experienced menarche when they were in grade four or below, and 16,893 students were assigned to the normal menarche group because they had experienced menarche during or after grade five. The characteristics of the sexual behaviors in the early menarche and normal menarche group were analyzed. Results The early menarche group was at a higher risk of intersexual kissing or petting (odds ratio [OR], 1.54; 95% confidence interval [CI], 1.28-1.87), intersexual intercourse (OR, 2.35; 95% CI, 1.65-3.36), homosexual kissing or petting (OR, 3.53; 95% CI, 2.22-5.59), homosexual intercourse (OR, 7.70; 95% CI, 4.04-14.66), being the victim (OR, 2.89; 95% CI, 1.98-4.22) or the assailant (OR, 13.55; 95% CI, 6.61-27.78) of sexual assaults, intercourse without any contraception (OR, 1.92; 95% CI, 1.06-3.46), and pregnancy (OR, 5.72; 95% CI, 2.31-14.15) than the normal menarche group. Conclusion Early menarche is associated with risky sexual behaviors among adolescent females; therefore, developing comprehensive sexual health education programs and tools for early intervention are required for children who are expected to experience early menarche.

    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

    Tobacco use is prevalent in the adolescent population. It is a major concern because tobacco is highly addictive and has also been linked to illicit drug use. There is not much research, however, on the interaction between nicotine and other stimulant drugs in animal models of early adolescence. This study examined the effects of chronic nicotine alone and on cocaine-stimulated activity in male and female periadolescent rats compared to male and female adult rats. During the seven-day nicotine pretreatment period, nicotine increased locomotor activity in all groups compared to vehicle controls. Male and female adult rats and female periadolescent rats developed sensitization to the locomotor-activating effects of nicotine over the 7-day treatment period, while male periadolescent rats did not. All groups treated with nicotine, however, exhibited sensitization to nicotine-induced repetitive motion over the 7-day nicotine treatment period. On day 8, male periadolescent rats pretreated with nicotine were more markedly sensitized to the locomotor-activating effects of cocaine than male adult rats, while female rats pretreated with nicotine were not sensitized to cocaine. In contrast, male and female periadolescent rats, but not adult rats, had increased amounts of repetitive beam breaks induced by cocaine after nicotine pretreatment. Overall, it appears that cross-sensitization to cocaine is greater in periadolescent than in adult rats, and that males are more sensitized than females. Thus, it may be that nicotine use during adolescence carries a greater risk than during adulthood and that male adolescents may be particularly vulnerable to the risk of cocaine abuse after nicotine use. This information should be taken into account so as to help us better understand the development of drug addiction in adolescents compared to adults.

    Background Globally adolescent fertility has been associated with increased risk to maternal and child health morbidity and mortality. The low use of contraception has been associated with high fertility levels, which is remains a public health concern that efforts have been raised to avert this. We examine the influence history of a previous birth and age at first birth would have on young women’s use of contraception. Methods Using the 2011 Uganda Demographic and Health Survey data, we examine the predictors of contraceptive use on a sample of 3692 young females in Uganda. While controlling for education and age of respondents, logistic regression analyses were run to provide the net effect of the examined predictors on contraceptive use. The study variables included age of respondents, marital status, age at first birth, births in past five years, socioeconomic status, residence, region, education level, religion, occupation and whether the last child was wanted. Results The findings show that only 12% of the adolescents were using contraception at the time of the survey. The key predictors of contraceptive use among young women in Uganda were age at first birth, history of previous birth, current age, and place of residence, education and socioeconomic status. Respondents who had a birth in the 5 years prior to the survey had five times (OR = 5.0, 95% CI = 3.7-6.5) the odds of contraceptive use compared to those who had never had a birth. Further, adolescent females with at least a secondary education were more likely to use contraceptives (OR = 1.55, 95% CI = 1.2-2.0) than those with primary education. The odds of contraceptive use were least among adolescents from Northern region (OR = 0.39, 95% CI = 0.2-0.6) compared to those from central region of Uganda. Muslim adolescent females were more likely to use contraceptives compared to Catholics (OR = 1.59, 95% CI = 1.1-2.3). Conclusion There is great need to address issues that hinder young people from using

    Ballet dancing is a multifaceted activity requiring muscular power, strength, endurance, flexibility, and agility; necessitating demanding training schedules. Furthermore dancers may be under aesthetic pressure to maintain a lean physique, and adolescent dancers require extra nutrients for growth and development. This cross-sectional study investigated the nutritional status of 47 female adolescent ballet dancers (13-18 years) living in Auckland, New Zealand. Participants who danced at least 1 hr per day 5 days per week completed a 4-day estimated food record, anthropometric measurements (Dual-energy X-ray Absorptiometry) and hematological analysis (iron and vitamin D). Mean BMI was 19.7 ± 2.4 kg/m2 and percentage body fat, 23.5 ± 4.1%. The majority (89.4%) of dancers had a healthy weight (5th-85th percentile) using BMI-for-age growth charts. Food records showed a mean energy intake of 8097.3 ± 2155.6 kJ/day (48.9% carbohydrate, 16.9% protein, 33.8% fat, 14.0% saturated fat). Mean carbohydrate and protein intakes were 4.8 ± 1.4 and 1.6 ± 0.5 g/kg/day respectively. Over half (54.8%) of dancers consumed less than 5 g carbohydrate/kg/day, and 10 (23.8%) less than 1.2 g protein/kg/day. Over 60% consumed less than the estimated average requirement for calcium, folate, magnesium and selenium. Thirteen (28.3%) dancers had suboptimal iron status (serum ferritin (SF) < 20 μg/L). Of these, four had iron deficiency (SF < 12 μg/L, hemoglobin (Hb) ≥ 120 g/L) and one iron deficiency anemia (SF < 12 μg/L, Hb < 120 g/L). Mean serum 25-hydroxy vitamin D was 75.1 ± 18.6 nmol/L, 41 (91.1%) had concentrations above 50 nmol/L. Female adolescent ballet dancers are at risk for iron deficiency, and possibly inadequate nutrient intakes.

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

    Objective To compare rates of contraception between reproductive-aged cancer survivors and women in the general U.S. population. Among survivors, the study examined factors associated with use of contraception and emergency contraception. Methods This study analyzed enrollment data from an ongoing national prospective cohort study on reproductive health after cancer entitled the Fertility Information Research Study. We compared current contraceptive use in survivors with that of the general population ascertained by the 2006–2010 National Survey for Family Growth. Log-binomial regression models estimated relative risks for characteristics associated with use of contraception, World Health Organization tiers I–II (sterilization and hormonal) contraceptive methods, and emergency contraception in survivors. Results Data from 295 survivors (mean age 31.6 ± 5.7 years, range 20–44 years) enrolled in this prospective study (85% response rate) were examined. Age-adjusted rates of using tiers I–II contraceptive methods were lower in survivors than the general population (34% [28.8–40.0] compared with 53% [51.5–54.5], P<.01). Only 56% of survivors reported receiving family planning services (counseling, prescription or procedure related to birth control) since cancer diagnosis. In adjusted analysis, receipt of family planning services was associated with both increased use of tiers I–II contraceptive methods (relative risk 1.3, 95% confidence interval [CI] 1.1–1.5) and accessing emergency contraception (relative risk 5.0, 95% CI 1.6–16.3) in survivors. Conclusion Lower rates of using Tiers I–II contraceptive methods were found in reproductive-aged cancer survivors compared to the general population of U.S. women. Exposure to family planning services across the cancer care continuum may improve contraception utilization among these women.

    The pelvic floor as lower closure of the abdominal cavity has to withstand the abdominal pressure. Meanwhile, the pelvic floor has to allow physiologic functions like micturition, defecation, sexual function and reproduction. But while pregnancy and vaginal delivery damage the pelvic floor directly, chronic stress like caugh, heavy lifting, or obesity lead to a chronic overstraining of the pelvic floor. Aging, structural changes, and possibly estrogen deficiency have a negative impact on the pelvic floor.

    PubMed

    Eiguer, A

    1996-12-01

    The author holds that the crisis of adolescence is in fact one of psychic reality, its elements being loss of boundaries, externalisation and the involvement of a third party. In this view, it is essential to conceive of adolescence differently from adulthood, in that, for example, an adolescent's acting out may not be solely a matter of regression but to a considerable extent a consequence of his or her physical development. It is noted that the boundaries between psychic and material reality are fluid throughout life and that adolescents crave identificatory models. The author stresses the importance of the psychic reality of the other in the adolescent's crisis. After considering various views, including those of Freud, on psychic reality and the crises of adolescence, he illustrates his thesis by the clinical example of two adolescent episodes of perversion forming part of an adult female patient's material. In the author's view, these instances of acting out had helped the patient to regain her auto-erotic capacity in the pleasure of fantasy life. He considers that a mutative interpretation must touch upon the primal fantasy and therefore involve the entire person of the analyst in the transference.

    This study examined the psychometric properties of a new scale to measure adolescents’ worry regarding outcomes of risky sexual behavior (i.e. sexually transmitted infections, including HIV [STI/HIV], and unintended pregnancy). The 10-item worry about sexual outcomes (WASO) scale, resulting in two subscales STI/HIV worry and pregnancy worry, was administered to a sample of 522 African-American female adolescents ranging in age from 14 to 18, residing in the southeast United States and participating in a sexual risk reduction intervention. The WASO demonstrated internal consistency across multiple administrations and yielded satisfactory construct validity. Worry was found to negatively correlate with sexual communication self-efficacy (with a new male partner and a steady male partner), frequency of sexual communication with male partner, attitudes about condom use and social support; worry was positively correlated with perceived barriers to condom use, condom negotiation, locus of control and depression. Overall, the results indicate that the WASO is a reliable and valid measure of assessing adolescents’ worry about STIs, HIV and pregnancy. The WASO represents a brief self-administered instrument that can be easily integrated into sexual risk reduction assessments and interventions. Future studies employing the WASO might consider testing it with more diverse samples in terms of gender, race/ethnicity, age and sexual orientation. PMID:18353760

    The aim of this study were to assess bullying and its associated factors in school-going adolescents in Thailand. Using data from the Thailand Global School-Based Student Health Survey (GSHS) 2008, the prevalence of being bullied and its associated factors among adolescents (N=2758) was assessed. The study found an overall prevalence of being bullied on one or more days during the past 30 days of 27.8%, 32.9% among males and 23.2% among females. The predominant forms of being bullied were among boys being hit, kicked, pushed, shoved around, or locked indoors and among girls making fun of with sexual jokes, comments, and gestures. Among boys risk factors for having been bullied were younger age (adjusted odds ratio to (AOR): 0.34; 95% confidence interval (CI): 0.18-0.65), having been in a physical fight (AOR: 3.64; 95% CI: 2.84-4.66), being physically inactive (AOR: 1.49; 95% CI: 1.04-2.15), truancy (AOR: 1.66; 95% CI: 1.13-2.45), and psychosocial distress (AOR: 2.07; 95% CI: 1.14-3.74), and among girls risk factors for having been bullied were having been in a physical fight (AOR: 2.91; 95% CI: 2.00-4.24), lack of parental bonding (AOR: 0.71; 95% CI: 0.51-0.99), and psychosocial distress (AOR: 2.37; 95% CI: 1.39-4.03). Results may inform school health programmes on the prevalence and correlates of bullying among adolescents in Thailand.

    Heightened impulsivity is a feature of some psychiatric disorders, including addiction, that also have sex-specific patterns of expression. The relationship between addiction and impulsivity may be driven by drug-induced changes in behavior caused by long term adaptations in signaling within the medial prefrontal cortex (mPFC). Here, we used a response inhibition task that is sensitive to changes in mPFC function to examine the effects of sex and exposure to amphetamine (AMPH) on impulsive action and vigilance. We also examined drug-induced alterations in glutamatergic and dopaminergic signaling through challenge injections with the NMDA receptor antagonist MK-801 (dizocilpine) and AMPH. Male and female Sprague Dawley rats were injected (i.p.) with saline or 3 mg/kg AMPH every other day during adolescence (postnatal day (P) 27–45) or adulthood (P85–103). Starting on P125–135, rats were tested for their ability to lever press for a food reward during periods of signaled availability and withhold responding during a “premature response” phase. In experiment 1, rats received challenge injections (i.p.) of MK-801 and AMPH followed by tests of task performance and locomotor activity. In experiment 2, rats received intra-mPFC infusion of MK-801. We found that females had better inhibitory control and poorer vigilance than males and that AMPH exposure had both sex- and age-of-exposure dependent effects on impulsivity. Systemic drug challenges disrupted task performance, particularly in females, and increased impulsivity while intra-mPFC infusions had modest effects. AMPH exposure did not affect responses to drug challenges. Together, these results suggest that sex mediates both trait and drug-induced impulsivity. PMID:24462963

    OBJECTIVE: To devise a flowchart suitable for assessing risk of trichomoniasis, chlamydia and gonorrhoea in an adolescent population, not all of whom will be sexually experienced or currently in a relationship. METHODS: The data used to derive the flowchart were generated from cross-sectional microbiological surveys of girls aged 14-19 years in Port Harcourt, Nigeria. The flowchart screened on the basis of: (i) sexual experience; (ii) recent sexual activity; (iii) a positive urine leukocyte esterase (LE) test; and (iv) among LE negatives, a history of malodorous/pruritic discharge. FINDINGS: Using this flowchart, we found that 26.2% of all adolescents screened would receive treatment for cervicitis and vaginitis. Chlamydial, gonococcal, and trichomonal infections were correctly diagnosed in 37.5%, 66.7%, and 50% of the cases, respectively. CONCLUSION: Although the flowchart is more suitable for an adolescent population than the vaginal discharge algorithm used in syndromic management protocols, it still lacks precision and needs adapting to local settings.

    Healthy brain aging and cognitive function are promoted by exercise. The benefits of exercise are attributed to several mechanisms, many which highlight its neuroprotective role via actions that enhance neurogenesis, neuronal morphology and/or neurotrophin release. However, the brain is also composed of glial and vascular elements, and comparatively less is known regarding the effects of exercise on these components in the aging brain. Here, we show that aerobic exercise at mid-age decreased markers of unhealthy brain aging including astrocyte hypertrophy, a hallmark of brain aging. Middle-aged female mice were assigned to a sedentary group or provided a running wheel for six weeks. Exercise decreased hippocampal astrocyte and myelin markers of aging but increased VEGF, a marker of angiogenesis. Brain vascular casts revealed exercise-induced structural modifications associated with improved endothelial function in the periphery. Our results suggest that age-related astrocyte hypertrophy/reactivity and myelin dysregulation are aggravated by a sedentary lifestyle and accompanying reductions in vascular function. However, these effects appear reversible with exercise initiated at mid-age. As this period of the lifespan coincides with the appearance of multiple markers of brain aging, including initial signs of cognitive decline, it may represent a window of opportunity for intervention as the brain appears to still possess significant vascular plasticity. These results may also have particular implications for aging females who are more susceptible than males to certain risk factors which contribute to vascular aging.

  20. Association between age at first sexual relation and some indicators of sexual behaviour among adolescents.

    2012-06-01

    This study explores the relationship between age at first sexual intercourse and four indicators of sexual behaviour among adolescents aged 14 to 19 years in Burkina Faso, Malawi and Uganda. Analyses are conducted using data from National Surveys of Adolescents, organized in 2004. Multivariate analyses are performed using dichotomous logistic regression and ordered polychotomic logistic regression. Analyses show that initiation of sexual activity before age 14 is more likely to be associated with having a casual sex partner. It is less likely to be associated with condom use at first sexual relation or with systematic condom use in the past 12 months. These associations vary depending on adolescents' country and gender. Delaying onset of sexuality could be a surer and safer way to protect health during adolescence. However, sexual and reproductive health programs that advocate abstinence only are likely to have few positive effects on young people. To better implement this strategy, sexual education for adolescents should be integrated.

    While adults are assumed to have the capacity to consent to medical research, and young children to have no capacity, adolescents' capacity to consent is not well described. Adapting the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), we describe adolescents' capacity to consent to medical research and factors influencing that capacity. Our pilot study included a community-based sample of 30 adolescents, 14 to 21 years of age, who completed the MacCAT-CR after undergoing a simulated informed consent process. We found that adolescents' capacity to consent to research was associated with age, health literacy, and family affluence. These findings suggest that investigators and institutional review boards should be aware that factors other than age may influence capacity to consent, and, for modifiable factors, such as health literacy, consent processes for medical research with adolescents can be modified.

    The purpose of this study was to develop and pilot-test an interactive CD-ROM aimed at the prevention of sexually transmitted infections (STIs) in female adolescents. The CD-ROM includes prevention information, models skills for negotiating abstinence and consistent condom use, teaches media literacy, and allows the user to choose a culturally appropriate host to guide them through the CD-ROM. Forty-seven female adolescents attending a health department clinic were randomized to receive the CD-ROM plus an educator-led didactic session versus the didactic session alone. The CD-ROM was highly acceptable and feasible for use among female adolescents in the clinic setting. Hispanic and African American adolescents were more likely to choose hosts of the same race/ethnicity to guide them through the CD-ROM. HIV/STI knowledge increased significantly and nearly all adolescents intended to use condoms at next intercourse after viewing the CD-ROM. However, there were no significant differences measured between CD-ROM and comparison groups.

    2016-04-01

    Individuals with greater expression of secondary sexual traits are often older and have higher survivorship than individuals with lower expression; if so, assessment of such indicator traits may provide genetic and/or direct benefits to potential mates. I examined the relationship between ornament expression, age, and survival in the striped plateau lizard, Sceloporus virgatus, a species with female-specific ornamentation that honestly signals reproductive quality. I followed a group of females from 2008 to 2013, examined ornament color and size as females aged, and compared ornamentation of survivors versus non-survivors. In addition, I explored whether other (non-ornamental) phenotypic characters predicted survival. I found that peak ornament expression (both color and size) of individual females changed year to year but appeared to be a weak signal of age due to high among-female variation in ornament expression that occurred independent of age and a non-linear pattern of change for ornament color. However, both absolute and relative ornament size did increase significantly as an individual aged and therefore may provide some age-related information such as reproductive investment, which is expected to increase as residual reproductive value declines with age. Individual survival was unrelated to peak ornament expression and to other phenotypic variables measured, providing no support for the ornament as a viability indicator and suggesting that individual survival prospects are affected by stochastic and environmental factors.

    2010-04-01

    This study aimed to explore the role of depression as a moderator of sociocultural influences on eating disorder symptoms. A sample of 509 adolescents (56% female) completed self-report questionnaires assessing depression, body dissatisfaction, drive for thinness, bulimic symptoms and sociocultural influences on appearance from family, peers and the media. Both girls and boys displaying high levels of depressive symptoms perceived stronger media and peer influences on appearance. Among girls, eating disorder symptoms were directly affected by sociocultural influences, in particular media influences, as well as by depression. However, depression played only a limited role as a moderator of these relationships. Among boys, sociocultural influences and depression revealed fewer direct effects on eating disorder symptoms. However, depression had a greater moderating effect on these relationships. Future research into the role of depression may increase the understanding of gender differences in body dissatisfaction, drive for thinness and bulimic symptoms.

    2012-11-01

    Aging results in reduced water and sodium intake responses in male rats. Because sex differences exist for water and sodium ingestion of young adult animals, we hypothesized that these sex differences would protect against the diminished water and sodium ingestion of aged female rats. Water and sodium intakes were examined in male and female young adult and aged Brown Norway rats in response to dipsogenic stimuli. Aged rats of both sexes consumed less water than young adult rats in response to 24-h water deprivation, thermal dehydration and hypertonic NaCl injection, but not to peripheral angiotensin II. Aged females consumed more water than males in response to hypertonic NaCl injection. Following sodium depletion, intake of 0.5 M NaCl solution over 2 h was higher in young adult rats than in aged rats. Aged animals had reduced angiotensin receptor 1A (AT(1A)) and atrial natriuretic peptide (ANP) mRNA expression in hypothalamic tissue with no sex differences. These data indicate that female rats are not protected from water and sodium intake deficits that occur in aging and that sex differences in sodium intake in young adult rats are eliminated with aging.

    Objective To determine the prevalence of vitamin D deficiency (<37.5 nmol/L) among young adolescents in Malaysia and its association with demographic characteristics, anthropometric measures and physical activity. Design This is a cross-sectional study among Form 1 (year 7) students from 15 schools selected using a stratified random sampling design. Information regarding sociodemographic characteristics, clinical data and environmental factors was collected and blood samples were taken for total vitamin D. Descriptive and multivariable logistic regression was performed on the data. Setting National secondary schools in Peninsular Malaysia. Participants 1361 students (mean age 12.9±0.3 years) (61.4% girls) completed the consent forms and participated in this study. Students with a chronic health condition and/or who could not understand the questionnaires due to lack of literacy were excluded. Main outcome measures Vitamin D status was determined through measurement of sera 25-hydroxyvitamin D (25(OH)D). Body mass index (BMI) was classified according to International Obesity Task Force (IOTF) criteria. Self-reported physical activity levels were assessed using the validated Malay version of the Physical Activity Questionnaire for Older Children (PAQ-C). Results Deficiency in vitamin D was seen in 78.9% of the participants. The deficiency was significantly higher in girls (92.6%, p<0.001), Indian adolescents (88.6%, p<0.001) and urban-living adolescents (88.8%, p<0.001). Females (OR=8.98; 95% CI 6.48 to 12.45), adolescents with wider waist circumference (OR=2.64; 95% CI 1.65 to 4.25) and in urban areas had higher risks (OR=3.57; 95% CI 2.54 to 5.02) of being vitamin D deficient. Conclusions The study shows a high prevalence of vitamin D deficiency among young adolescents. Main risk factors are gender, ethnicity, place of residence and obesity. PMID:27540095

    The current study examined how parents' use of restrictive and active monitoring and deference changed over three years, and examined both adolescent and parent characteristics as predictors of initial levels of media monitoring, as well as change in media monitoring. Participants included 276 mother-child dyads (M age of child = 12.08, SD = .63, 50% female) taken from Time 2 of the Flourishing Families Project, 96% of whom had complete data for Time 4 (N = 266). Active monitoring was the most common approach at the first and second time points, while active monitoring and deference were equally common by the final time point. Latent growth curve analysis revealed that restrictive and active monitoring decreased over time, while deference increased. In addition, both adolescent and parent characteristics were predictive of initial levels of all three types of monitoring, and of change in restrictive monitoring. Discussion focuses on developmental implications of these findings.

    2010-01-01

    PURPOSE. This case study was written to demonstrate the usefulness of standardized nursing diagnoses, outcomes, and interventions in nurse anesthetist care of an adolescent trauma patient. DATA SOURCES. Literature reviews using Academic Premier, Google Scholar, and CINAHL databases were done to find current, relevant articles concerning evaluation and support of female African-American adolescents living in socially vulnerable and economically exploited environments. DATA SYNTHESIS. A case is presented and evidence from current publications is analyzed to support the diagnosis, outcomes, and interventions. CONCLUSION. The investment in extra time, care, and effort sometimes required for the full development of a treatment plan for teenagers who live where they are at high risk for violence and other consequences of stressful environments is a worthwhile one, even if results may require contact over an extended time period. PRACTICE IMPLICATIONS. Nurses of all specialty backgrounds need to be concerned with the progress of their patients. Sometimes nurses can best serve their patients by stepping away from the physiological event and focusing instead on responses in the domain of coping and stress tolerance as the root of difficulties.

    Objective Age screening and preventive medication for future myocardial infarction and stroke has been previously described. We aimed to ascertain whether different age cut-offs are needed for males and females. Methods We determined five parameters for each sex according to age cut-off: detection rate (sensitivity), false-positive rate, proportion of the population eligible for treatment with a polypill, proportion who benefit from taking a polypill (simvastatin 20 mg, losartan 25 mg, hydrochlorothiazide 12.5 mg, amlodipine 2.5 mg), and among these, years of life gained without a first myocardial infarction or stroke. Results Approximately one-third benefit, regardless of the age cut-off. For males and females combined, using ages 40 and 80, the detection rates are 98% and 52%, false-positive rates are 51% and 7%, population percentages eligible for treatment are 52% and 7%, and years of life gained without a first myocardial infarction or stroke are 8.4 and 3.6. Using age 50, detection rates are 93% (males) 98% (females), false-positive rates 37% (males) 40% (females), percentage of the population eligible for treatment 38% (males) 41% (females), percentage who benefit 35% (males) 33% (females), and years of life gained without an event 8.5 (males) 7.0 (females). At a given age cut-off, the sex differences are relatively small. Conclusion A single age cut-off can be used for both sexes.

  12. Persistent Genital Hyperinnervation Following Progesterone Administration to Adolescent Female Rats1

    Liao, Zhaohui; Smith, Peter G.

    2014-01-01

    ABSTRACT Provoked vestibulodynia, a female pelvic pain syndrome affecting substantial numbers of women, is characterized by genital hypersensitivity and sensory hyperinnervation. Previous studies have shown that the risk of developing provoked vestibulodynia is markedly elevated following adolescent use of oral contraceptives with high progesterone content. We hypothesized that progesterone, a steroid hormone with known neurotropic properties, may alter genital innervation through direct or indirect actions. Female Sprague Dawley rats received progesterone (20 mg/kg subcutaneously) from Days 20–27; tissue was removed for analysis in some rats on Day 28, while others were ovariectomized on Day 43 and infused for 7 days with vehicle or 17beta estradiol. Progesterone resulted in overall increases in vaginal innervation at both Day 28 and 50 due to proliferation of peptidergic sensory and sympathetic (but not parasympathetic) axons. Estradiol reduced innervation in progesterone-treated and untreated groups. To assess the mechanisms of sensory hyperinnervation, we cultured dissociated dorsal root ganglion neurons and found that progesterone increases neurite outgrowth by small unmyelinated (but not myelinated) sensory neurons, it was receptor mediated, and it was nonadditive with NGF. Pretreatment of ganglion with progesterone also increased neurite outgrowth in response to vaginal target explants. However, pretreatment of vaginal target with progesterone did not improve outgrowth. We conclude that adolescent progesterone exposure may contribute to provoked vestibulodynia by eliciting persistent genital hyperinnervation via a direct effect on unmyelinated sensory nociceptor neurons and that estradiol, a well-documented therapeutic, may alleviate symptoms in part by reducing progesterone-induced sensory hyperinnervation.

    The purpose of this study was to examine the direct and indirect ecological influences of teacher and friend social support on body weight and diet behaviors in African-American adolescent females. Using a quantitative, cross-sectional research design, a convenience sample of 182 urban African-American adolescent females (12–17 years old) completed a 39-item questionnaire. The questionnaire assessed perceived teacher social support, friend social support, nutrition self-efficacy, and diet behaviors (with internal reliability values of scale items: alpha=0.74, 0.81, 0.77, and 0.69 respectively). Anthropometric assessments were conducted to measure height and weight to compute BMI. Majority of the participants were in middle or early high school (65 %) and were overweight or obese (57.7 %). Both teacher social support and friend social support demonstrated a positive, indirect influence on child weight status through nutrition self-efficacy and diet behaviors following two different and specific paths of influence. Diet behaviors, in turn, demonstrated a positive, direct effect on child weight status. In the structural model, teacher social support had the greatest effect on diet behaviors, demonstrating a direct, positive influence on diet behaviors (B=0.421, p<0.05), but its direct effect on nutrition self-efficacy was not significant. Friend social support demonstrated a positive, direct effect on nutrition self-efficacy (B=0.227, p<0.05), but its direct effect on diet behaviors was not statistically significant. The study’s findings call for actively addressing the childhood obesity epidemic in the school environment by implementing health behavior change strategies at various social and ecological environmental levels.

    Among various factors influencing mood disorders, the impact of micronutrient deficiencies has attracted a great attention. Zinc deficiency is considered to play a crucial role in the onset and progression of mood disorders in different stages of life. The main objective of this study was to assess the correlation between serum zinc levels and mood disorders in high school female students. This cross-sectional study was conducted on a random sample of 100 representative high school female students. The participants completed 24-h food recall questionnaires to assess the daily zinc intakes. Serum zinc status was assessed using flame atomic absorption spectrometry, and zinc deficiency was defined accordingly. Mood disorders were estimated by calculating the sum of two test scores including Beck's depression inventory (BDI) and hospital anxiety depression scale (HADS) tests. General linear model (GLM) and Pearson's regression test were applied to show the correlation of serum zinc levels and mood disorder scores and the correlation between zinc serum levels and BDI scores, respectively. Dietary zinc intake was higher in subjects with normal zinc concentrations than that of zinc-deficient group (p = 0.001). Serum zinc levels were inversely correlated with BDI and HADS scores (p < 0.05). Each 10 μg/dL increment in serum zinc levels led to 0.3 and 0.01 decrease in depression and anxiety scores, respectively (p < 0.05). Serum zinc levels were inversely correlated with mood disorders including depression and anxiety in adolescent female students. Increasing serum levels of zinc in female students could improve their mood disorders.

    Objective To determine the relationship between relative body composition and body mass to height, anterior knee pain, or patellofemoral pain (PFP) in adolescent female athletes. Background Patellofemoral pain is common in female athletes and has an undefined etiology. The purpose of this study was to examine whether there was an association among higher body mass index (BMI), BMI z-scores, and relative body fat percentage in the development of PFP in an adolescent female athlete population. We hypothesized that female athletes who developed PFP over the course of a competitive basketball season had higher relative body mass or body fat percentage compared with those who did not develop PFP. Methods Fifteen middle school basketball teams that consisted of 248 basketball players (mean age, 12.76 ± 1.13 years; height, 158.43 ± 7.78 cm; body mass, 52.35 ± 12.31 kg; BMI, 20.73 ± 3.88 kg/m2) agreed to participate in this study over the course of 2 basketball seasons, resulting in 262 athlete-seasons. Testing included the completion of the Anterior Knee Pain Scale (AKPS), International Knee Documentation Committee (IKDC) form, standardized history, physician-administered physical examination, maturational estimates, and anthropometrics. Results Of the 262 athlete-seasons monitored, 39 athletes developed PFP over the course of the study. The incidence rate of new PFP was 1.57 per 1000 athlete-exposures. The cumulative incidence of PFP was 14.9%. There was no difference in BMI between those who developed PFP (mean body mass, 20.2 kg/m2; 95% CI, 18.9–21.4) and those who did not develop PFP (mean body mass, 20.8 kg/m2; 95% CI, 20.3–21.3; P > 0.05). Body mass index z-scores were not different between those who developed PFP (mean, 0.3; 95% CI, 0.7–0.6) and those who did not develop PFP (mean, 0.4; 95% CI, 0.3–0.6; P > 0.05). A similar trend was noted in relative body fat percentage, with mean scores of similar ranges in those who developed PFP (mean body fat

    Unequal gender norms and age-disparate sexual relationships can lead to power imbalances and are also associated with intimate partner violence (IPV), sexual coercion and violence, and sexual risk behaviors. The present study examined these variables from both victim and perpetrator perspectives among adolescent gang members. Age-disparate sexual relationships were defined as sex partners 5 or more years older among female participants and 5 or more years younger among male participants. Participants were recruited from a mid-sized Midwestern city and completed a 60-90-min audio computer-assisted self-interview in a community-based setting. Participants in this study included 107 female gang members (68 % African-American, 19 % Latina; mean age, 17.6) and 169 male gang members (62 % African-American, 28 % Latino; mean age, 17.7). As hypothesized, endorsing unequal gender norms toward women was significantly related to IPV victimization among female participants and perpetration among male participants, and engagement in group sex in the past month among both female and male participants (ps < 0.05). Additionally, unequal gender norms were significantly related to male participants' perpetrating rape (p < 0.05). As hypothesized, female gang members who had been in age-disparate sexual relationships were significantly more likely to have experienced more IPV and report being raped and males gang members who had age-disparate sexual relationships were significantly more likely to perpetrate IPV in the past year and perpetrate rape (ps < 0.05). Age-disparate sexual relationships were also significantly related to being gang raped among female gang members and participating in a gang rape among male gang members, and engaging in group sex among both female and male gang members (ps < 0.05). Female participants who had been in age-disparate sexual relationships were more likely to have been pregnant (ps < 0.05). It is essential for researchers and

    Human female life expectancy is higher than that of males. Intriguingly, it has been reported that women display faster rates of age-related cognitive decline and a higher prevalence of Alzheimer's disease (AD). To assess the molecular bases of these contradictory trends, we analyzed differences in expression changes with age between adult males and females, in four brain regions. In the superior frontal gyrus (SFG), a part of the prefrontal cortex, we observed manifest differences between the two sexes in the timing of age-related changes, that is, sexual heterochrony. Intriguingly, age-related expression changes predominantly occurred earlier, or at a faster pace, in females compared to men. These changes included decreased energy production and neural function and up-regulation of the immune response, all major features of brain aging. Furthermore, we found that accelerated expression changes in the female SFG correlated with expression changes observed in AD, as well as stress effects in the frontal cortex. Accelerated aging-related changes in the female SFG transcriptome may provide a link between a higher stress exposure or sensitivity in women and the higher prevalence of AD.

  1. Media Use in School-Aged Children and Adolescents.

    PubMed

    2016-11-01

    This policy statement focuses on children and adolescents 5 through 18 years of age. Research suggests both benefits and risks of media use for the health of children and teenagers. Benefits include exposure to new ideas and knowledge acquisition, increased opportunities for social contact and support, and new opportunities to access health-promotion messages and information. Risks include negative health effects on weight and sleep; exposure to inaccurate, inappropriate, or unsafe content and contacts; and compromised privacy and confidentiality. Parents face challenges in monitoring their children's and their own media use and in serving as positive role models. In this new era, evidence regarding healthy media use does not support a one-size-fits-all approach. Parents and pediatricians can work together to develop a Family Media Use Plan (www.healthychildren.org/MediaUsePlan) that considers their children's developmental stages to individualize an appropriate balance for media time and consistent rules about media use, to mentor their children, to set boundaries for accessing content and displaying personal information, and to implement open family communication about media.

    2007-02-01

    Age-appropriate communication style is a core condition in order to screen successfully for exploratory behaviours during adolescence. To offer the adolescent patient to see the doctor alone for some time and to provide assurance of confidentiality even with regard to their parents enhances the doctor-patient relationship and enables the communication about personal issues such as the consumption of psychoactive substances and other potentially harmful behaviours. In order to assure confidentiality even with regard to the adolescent's parents, an evaluation of the adolescent patient's rights for minor consent as well as the potential risk for self-harm and / or homicide has to be performed. Age-appropriate communication that includes conversation about psychoactive drugs and other harmful behaviours has the potential to improve the adolescents' health substantially.

    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

    This study continues a longitudinal analysis of rhesus macaque social behavior following bilateral neonatal ibotenic acid lesions of the amygdala or hippocampus, or sham operations. The social behavior of female subjects was evaluated at a critical developmental time point-the transition to adulthood. At approximately 4 years of age, female subjects were housed in small groups with other female subjects and reproductively viable adult males. As compared with neurologically intact control animals and animals with early amygdala damage, animals with early hippocampal damage were more social with their female peers. In contrast, as compared with control animals, animals with early amygdala damage spent less time with the males, engaged less frequently in behaviors typical of reproductive consortships, had higher frequencies of self-directed stereotypies, and became pregnant later. Males also generated fewer communicative signals toward animals with early amygdala damage than to control animals and animals with early hippocampus damage. Rates of sexual behavior were generally low for all animals, and there were no lesion-based differences in their frequencies. Discriminant function analyses demonstrated that patterns of affiliative social behaviors differed across the 3 experimental groups, both in terms of the social behaviors directed to the males, and the social behaviors generated by the males toward the females. In 4 of the 5 social groups, amygdala-lesioned animals were lowest ranked, potentially contributing to reduced sociability interactions with males. Other potential mechanisms and the experiments needed to elucidate them are discussed. (PsycINFO Database Record

    The objectives of the current study were to explore: (1) the association between the social environment at the city and family levels and risky eating behaviors in adolescent females and (2) the interaction between the social and cultural environment and body mass index (BMI). The data were obtained from a representative survey of female high school students in Mexico State, Mexico (15-19 years). A questionnaire was applied on risky eating behaviors and socio-demographic data. The municipal social and cultural environment was evaluated using the municipal marginalization index. Data analysis used multivariate regression. Prevalence of risky eating behaviors was 4.23%. BMI and family socioeconomic status were directly associated with risky eating behaviors. The municipal marginalization index was not associated with risky eating behaviors. Possible explanations for the latter are that the relevant components of the social and cultural environment were not measured, or that the municipal level does not exert a contextual effect on risky eating behaviors. The effect of BMI on risky eating behaviors was greater in more marginalized municipalities.

    Exposure to multiple traumatic events and high rates of mental health problems are common among juvenile offenders. This study draws on Conservation of Resources (COR) stress theory to examine the impact of a specific trauma, Hurricane Katrina, relative to other adverse life events, on the mental health of female adolescent offenders in Mississippi. Teenage girls (N=258, 69% African American) were recruited from four juvenile detention centers and the state training school. Participants were interviewed about the occurrence and timing of adverse life events and hurricane-related experiences and completed a self-administered mental health assessment. Hierarchical linear regression models were used to identify predictors of anxiety and depression. Pre-hurricane family stressors, pre-hurricane traumatic events, hurricane-related property damage, and receipt of hurricane-related financial assistance significantly predicted symptoms of anxiety and depression. Findings support COR theory. Family stressors had the greatest influence on symptoms of anxiety and depression, highlighting the need for family based services that address the multiple, inter-related problems and challenges in the lives of female juvenile offenders.

    A 16-year-old female presented with dribbling of urine along with voluntary voiding since birth. Renal imaging revealed hydroureteronephrosis on the right side; the uterus and ovary were normal. A radionuclide scan showed a left nonfunctional kidney. On cystovaginoscopy, the urethra was shown to be normal and the urinary bladder was tubular with small capacity and an absent trigone. Although the vagina was capacious, no ureteric orifices were found. Computed tomography corroborated the diagnosis of bilateral, single ectopic ureters draining into a grossly dilated vagina. This case is unique because it is a bilateral single-system ureteral ectopia in a completely differentiated female genital tract that presented late in adolescence. To the best of our knowledge, this is the second such ureteral abnormality reported in the literature so far. The patient underwent ileocystoplasty with right ureteric reimplantation and nephroureterectomy for the left nonfunctional kidney, which histopathology showed to be tuberculosis. The patient is continent with cystometric capacity of more than 300 mL. PMID:23878693

    Women and girls' engagement in antisocial behavior represents a psychological issue of great concern given the radiating impact that women's antisociality can have on individuals, families, and communities. Despite its importance and relevance for psychological science, this topic has received limited attention to date and no systematic review of risk factors exists. The present paper aims to systematically review the empirical literature informing risk factors relevant to women's antisocial behavior, with a focus on adolescence and adulthood. Primary aims are to 1) review empirical literatures on risk factors for female antisocial behavior across multiple levels of influence (e.g., person-level characteristics, risky family factors, and gender-salient contexts) and fields of study (e.g., psychology, sociology); 2) evaluate the relevance of each factor for female antisocial behavior; and 3) incorporate an analysis of how gender at both the individual and ecological levels shapes pathways to antisocial behavior in women and girls. We conclude that women's antisocial behavior is best-understood as being influenced by person-level or individual vulnerabilities, risky family factors, and exposure to gender-salient interpersonal contexts, and underscore the importance of examining women's antisocial behavior through an expanded lens that views gender as an individual level attribute as well as a social category that organizes the social context in ways that may promote engagement in antisocial behavior. Based on the present systematic review, an integrative pathway model is proposed toward the goal of synthesizing current knowledge and generating testable hypotheses for future research.

    Partner age is associated with youth's sex risk behaviors and sexually transmitted infections. At present, however, it is not known whether the co-occurrence of other risk behaviors is associated with having older sex partners during adolescence and young adulthood. Using growth curve modeling, this study first describes the shape of the age difference between participants and their sex partners across adolescence and young adulthood in a sample of African American youth. Second, whether this model varied systematically by sex, mother's education, and high school dropout was tested. Third, whether age differences were associated with youth's self-acceptance, alcohol use, and employment trajectories over these two developmental periods was assessed. Finally, whether these associations had non-proportional effects over both periods was tested. This study modeled sex partners' age differences nonlinearly, with females being more likely to date older partners at baseline and over time. High school dropouts also reported older partners at baseline. Self-acceptance and the number of hours worked were associated with sex partners' age differences over time, with the effect decreasing over young adulthood years. Alcohol use frequency was also associated with having older partners over time. This study discusses the findings from a health perspective on youth's sexual development.

    Information is sparse about aspects of female wolf (Canis lupus) breeding in the wild, including age of first reproduction, mean age of primiparity, generation time, and proportion of each age that breeds in any given year. We studied these subjects in 86 wolves (113 captures) in the Superior National Forest (SNF), Minnesota (MN), during 1972–2013 where wolves were legally protected for most of the period, and in 159 harvested wolves from throughout MN wolf range during 2012–2014. Breeding status of SNF wolves were assessed via nipple measurements, and wolves from throughout MN wolf range, by placental scars. In the SNF, proportions of currently breeding females (those breeding in the year sampled) ranged from 19% at age 2 to 80% at age 5, and from throughout wolf range, from 33% at age 2 to 100% at age 7. Excluding pups and yearlings, only 33% to 36% of SNF females and 58% of females from throughout MN wolf range bred in any given year. Generation time for SNF wolves was 4.3 years and for MN wolf range, 4.7 years. These findings will be useful in modeling wolf population dynamics and in wolf genetic and dog-domestication studies.

    Objective: The aim of the present study was to document ovarian cyst frequency and characteristics as well as distribution of these parameters with respect to age in children and adolescents. Methods: We retrospectively analyzed the medical records of 1009 girls between the ages of 5-18 years who presented to our pediatric emergency department (PED) with pelvic pain and therefore underwent pelvic ultrasound examination between June 2011 and May 2014. Results: In total, 132 of 1009 girls (13.1%) were identified as having ovarian cysts ≥1 cm in diameter. The frequency of ovarian cysts was found to be 1.8% (6/337) in children aged 5-9 years and 18.8% (126/672) in those aged 10-18 years. All the cysts detected in children aged 5-9 years were small (<3 cm) and simple with age-specific frequencies ranging between 1.5-2.7%. With the onset of adolescence, ovarian cyst frequency started to increase with age and ranged between 3.8-31.3% throughout adolescence. Age of peak ovarian cyst frequency was 15 years with a rate of 31.3%. Large ovarian cysts (>5 cm) were identified in 19 adolescents (15.1%) with most occurring during middle adolescence. Of the 19 adolescents, five were found to have cyst-related significant ovarian pathologies including cystadenoma (n=3) and ovarian torsion (n=2). Conclusion: In children aged 5-9 years, ovarian cysts were infrequent and small (<3 cm). Peak ovarian cyst frequency was detected at the age of 15 years. All patients diagnosed with cyst-related significant ovarian pathologies were adolescents having a cyst >5 cm in diameter with a complex appearance in most. PMID:28044991

    Effects of nine social life indicators on age-adjusted and age-specific annual suicide mortality of male and female Japanese population in the years 1953-96 were investigated by multiple regression analysis on time series data. Unemployment rate was significantly related to the age-adjusted mortality in both males and females. Also, female labour force participation was positively related to the male mortality; persons and 65 and above was inversely related to the male mortality. Results on the age-specific mortality indicated that: during the 44 yr, (1) unemployment significantly related with the mortality of young, middle-aged and elderly males and young females; (2) female labour force participation significantly related with the mortality of young and elderly males and young females; aged population significantly related with the mortality of middle-aged and elderly males; (4) young population significantly related with the mortality of young and middle-aged males and females; (5) divorce significantly related with the mortality of middle-aged and elderly males and young males and females; (6) persons employed in primary industries significantly related with the mortality in middle-aged males and young males and females; and (7) population density significantly related with the mortality of middle-aged males and young females.

    Adverse early life experiences can potentially increase risk for drug abuse later in life. However, little research has been conducted studying the effects of maternal separation (MS), an experimental model for early life stress, on the rewarding effects of nicotine. Cognitive function may be affected by MS. So, we also investigated whether nicotine administration affect spatial learning and memory in MS adolescent female rats. Rat pups were subjected to daily MS for 15min (MS15) or 180min (MS180) during the first 2 weeks of life or reared under normal animal facility rearing (AFR) conditions. The place preference test was performed with nicotine (0.6mg/kg,s.c.) or vehicle over a period of 6 conditioning trials during adolescence. Spatial learning and memory performance was evaluated by using Morris water maze (MWM). In our study, adolescent female rats exposed to MS180 shown a significantly greater preference for a nicotine-paired compartment during the testing phase than the MS15 group. Nicotine altered the MS-induced spatial learning defects in the MS180 group. These findings suggest that MS may increase sensitivity to the rewarding effects of nicotine and also it is possible to suggest that nicotine administration may influence learning dysfunction induced by MS in adolescent female rats.

    Mental health problems including emotional and behavioral problems during puberty may be under influence of different risk factors including cultures, living in urban or rural areas and ethnic factors which may vary between different countries. The main aim of this study is to investigate the profile of emotional and behavioral problems and the role of factors such as age, stage of puberty, ethnicity, rurality and living in urban area, as risk factors in Iranian girls. As a part of a large national study we evaluated the emotional and behavioral problems in different stages of puberty in a community sample of Iranian adolescent girls from public schools that were selected by clustered random sampling method. In all subjects, demographic characteristics, and pubertal stages were measured. Emotional and behavioral problems were evaluated using Strength and Difficulties Questionnaire (SDQ). The associations of age, pubertal development indices, socioeconomic and demographic factors with the behavioral problems were assessed. A total number of 4576 students enrolled the study and responded to the questions. The mean age of participants was 13.83 ± 2.19 years. The mean total score of difficulties in participants was 14.34 ± 5.81. According to these results 813 (17.8%) adolescents had total problem scores higher than Goodman's cutoff points and the most frequent problem domain was conduct problems (20.5%). According to the results the most related variable with the total difficulty score of SDQ were ethnicity, residency in urban areas and development of menstrual cycle respectively. The results of this study showed that the most correlated factors with mental health problems in Iranian girls during puberty are ethnicity, urbanity and development of menstrual cycle.

    Little is known about the factorial invariance across gender and age for self-report measures of social anxiety in adolescence. This study examined the factorial invariance and latent mean differences of the Social Anxiety Scale for Adolescents (SAS-A) across gender and age groups in 1570 Spanish adolescents (54% girls), ranging in age from 14 to 17 years. Equality of factor structures was compared using multi-group confirmatory factor analyses. Measurement invariance for the correlated three-factor model of the SAS-A was found across gender and age samples. Analyses of latent mean differences revealed that girls exhibited higher means than boys on two SAS-A subscales, Fear of Negative Evaluation and Social Avoidance and Distress-New (SAD-New). In addition, on the SAD-New subscale, the structured means significantly diminished from 14-year olds to 16- and 17-year olds and from 15-year olds to 17-year olds. Findings are discussed in terms of the use of the SAS-A with Spanish adolescents.

    For asthma and psychological morbidity, it is well established that higher prevalence among males in childhood is replaced by higher prevalence among females by adolescence. This review investigates whether there is evidence for a similar emerging female 'excess' in relation to a broad range of physical morbidity measures. Establishing whether this pattern is generalised or health outcome-specific will further understandings of the aetiology of gender differences in health. Databases (Medline; Embase; CINAHL; PsycINFO; ERIC) were searched for English language studies (published 1992-2010) presenting physical morbidity prevalence data for males and females, for at least two age-bands within the age-range 4-17 years. A three-stage screening process (initial sifting; detailed inspection; extraction of full papers), was followed by study quality appraisals. Of 11 245 identified studies, 41 met the inclusion criteria. Most (n = 31) presented self-report survey data (five longitudinal, 26 cross-sectional); 10 presented routinely collected data (GP/hospital statistics). Extracted data, supplemented by additional data obtained from authors of the included studies, were used to calculate odds ratios of a female excess, or female:male incident rate ratios as appropriate. To test whether these changed with age, the values were logged and regressed on age in random effects meta-regressions. These showed strongest evidence of an emerging/increasing female excess for self-reported measures of headache, abdominal pain, tiredness, migraine and self-assessed health. Type 1 diabetes and epilepsy, based on routinely collected data, did not show a significant emerging/increasing female excess. For most physical morbidity measures reviewed, the evidence broadly points towards an emerging/increasing female excess during the transition to adolescence, although results varied by morbidity measure and study design, and suggest that this may occur at a younger age than previously thought.

    Existing studies of the labor market status of cancer survivors have focused on the extent to which cancer disrupts the employment of individuals who were working when diagnosed with cancer. We examine how surviving cancer affects labor market entry and usual hours of work among females aged 28 to 54 years who were not working when first diagnosed. We find that prime-age females have employment rates 2 to 6 years after diagnosis that are 12 percentage points lower than otherwise similar women who were initially out of the labor force, full-time employment rates that are 10 percentage points lower, and usual hours of work that are 5 hours per week lower. These estimates are somewhat larger than estimates for prime-age women employed at the time of diagnosis and highlight the importance of considering nonworking females when assessing the economic and psychosocial burden of cancer.

    Background Prevention of substance use disorder (SUD) is impeded by the large number, complexity and idiosyncratic configuration of etiological factors. Effective prevention of SUD is feasible however when intervention resources are prioritized to individuals who are objectively determined as high risk and tailored to their specific characteristics and circumstances. Objective This study had the aim of developing a rapid accurate screening instrument for determining current presence of and future risk for SUD. Methods The sample consisted of 182 girls recruited when they were 10–12 years of age and tracked to 22 years of age. From a large item pool the Drug Use Screening Inventory Quick Screen for Females (DQS-F) was derived consisting of the Substance Involvement Index and the Problem Severity Index. Results The DQS for Females (DQS-F) has high sensitivity for identifying girls who currently qualify for SUD diagnosis. Furthermore, accuracy of predicting future SUD with the DQS-F is in the good range at age 16 and in the very good range at age 19. Conclusions Requiring only three minutes for administration on the Web the DQS-F is an efficient method for identifying girls requiring thorough assessment prior to implementing individualized intervention PMID:25089182

    Aging is associated to oxidative damage and alterations in inflammatory and apoptotic pathways. Aging impairs secretion of several hormones, including melatonin and estrogens. However, the mechanisms involved in aging of smooth muscle are poorly known. We have studied the changes induced by aging in the colonic smooth muscle layer of female rats and the protective effect of hormonal therapy. We used young, aged, and ovariectomized aged female rats. Two groups of ovariectomized rats (22 months old) were treated either with melatonin or with estrogen for 10 weeks before sacrifice. Aging induced oxidative imbalance, evidenced by H(2)O(2) accumulation, lipid peroxidation, and decreased catalase activity. The oxidative damage was enhanced by ovariectomy. In addition, aged colonic muscle showed enhanced expression of the pro-inflammatory enzyme cyclooxygenase 2. Expression of the activated forms of caspases 3 and 9 was also enhanced in aged colon. Melatonin and estrogen treatment prevented the oxidative damage and the activation of caspases. In conclusion, aging of colonic smooth muscle induces oxidative imbalance and activation of apoptotic and pro-inflammatory pathways. Hormonal therapy has beneficial effects on the oxidative and apoptotic changes associated to aging in this model.

    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.

    Context Single-sport specialization (SSS) is becoming more prevalent in youth athletes. Deficits in functional movement have been shown to predispose athletes to injury. It is unclear whether a link exists between SSS and the development of functional movement deficits that predispose SSS athletes to an increased risk of knee injury. Objective To determine whether functional movement deficits exist in SSS athletes compared with multi-sport (M-S) athletes. Design Cross-sectional study. Setting Soccer practice fields. Patients or Other Participants A total of 40 (21 SSS [age = 15.05 ± 1.2 years], 19 M-S [age = 15.32 ± 1.2 years]) female high school athlete volunteers were recruited through local soccer clubs. All SSS athletes played soccer. Intervention(s) Participants were grouped into 2 categories: SSS and M-S. All participants completed 3 trials of the standard Landing Error Scoring System (LESS) jump-landing task. They performed a double-legged jump from a 30-cm platform, landing on a rubber mat at a distance of half their body height. Upon landing, participants immediately performed a maximal vertical jump. Main Outcome Measure(s) Values were assigned to each trial using the LESS scoring criteria. We averaged the 3 scored trials and then used a Mann-Whitney U test to test for differences between groups. Participant scores from the jump-landing assessment for each group were also placed into the 4 defined LESS categories for group comparison using a Pearson χ2 test. The α level was set a priori at .05. Results Mean scores were 6.84 ± 1.81 for the SSS group and 6.07 ± 1.93 for the M-S group. We observed no differences between groups (z = −1.44, P = .15). A Pearson χ2 analysis revealed that the proportions of athletes classified as having excellent, good, moderate, or poor LESS scores were not different between the SSS and M-S groups ( = 1.999, P = .57). Conclusions Participation in soccer alone compared with multiple sports did not affect LESS scores in

    The effect of the constant illumination on the development of spontaneous tumors in female 129/Sv mice was investigated. Forty-six female 129/Sv mice starting from the age of 2 mo were kept under standard light/dark regimen [12 h light (70 lx):12hr dark; LD, control group], and 46 of 129/Sv mice were kept under constant illumination (24 h a day, 2,500 lx, LL) from the age of 5 mo until to natural death. The exposure to the LL regimen significantly accelerated body weight gain, increased body temperature as well as acceleration of age-related disturbances in estrous function, followed by significant acceleration of the development of the spontaneous uterine tumors in female 129/Sv mice. Total tumor incidence as well as a total number of total or malignant tumors was similar in LL and LD group (p > 0.05). The mice from the LL groups survived less than those from the LD group (χ2 = 8.5; p = 0.00351, log-rank test). According to the estimated parameters of the Cox’s regression model, constant light regimen increased the relative risk of death in female mice compared with the control (LD) group (p = 0.0041). The data demonstrate in the first time that the exposure to constant illumination was followed by the acceleration of aging and spontaneous uterine tumorigenesis in female 129/Sv mice. PMID:23656779

    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.

    A substantial body of evidence documents that the frequency and intensity of posttraumatic stress disorder (PTSD) symptoms are linked to such demographic variables as female sex (e.g., Kaplow et al., 2005) and age (e.g., Meiser-Stedman et al., 2008). Considerably less is known about relations between biological sex and age with PTSD's latent factor structure. This study systematically examined the roles that sex and age may play as candidate moderators of the full range of factor structure parameters of an empirically supported five-factor PTSD model (Elhai et al., 2011). The sample included 6591 trauma-exposed children and adolescents selected from the National Child Traumatic Stress Network's Core Data Set. Confirmatory factor analysis using invariance testing (Gregorich, 2006) and comparative fit index difference values (Cheung and Rensvold, 2002) reflected a mixed pattern of test item intercepts across age groups. The adolescent subsample produced lower residual error variances, reflecting less measurement error than the child subsample. Sex did not show a robust moderating effect. We conclude by discussing implications for clinical assessment, theory building, and future research.

    To evaluate the age-related changes in capacity to adjust the nutrient intake to needs, self-selecting male and female Lou/C/jall rats of 4, 6, 12, 16 and 23 months of age were submitted to a swimming exercise. They were given 6 consecutive days of moderate intensity training (3 x 15 minutes per day). Exercise and postexercise periods were compared with results from the pretraining period. During swimming, a body weight loss and a decrease in both caloric intake and fat selection were observed. This effect was more marked in older groups compared to 4 month-old groups. An increase in protein intake was observed in females, specially in older groups, whereas no effect was seen in males. The ability to increase caloric ingestion and regain weight during the postexercise period decreased with advancing age and was better in females than in males. We also showed an age-related effect on the recovery of initial nutrient intake rate that was more pronounced and more precocious for males. Moreover, males tended to decrease their protein intake, whereas females significantly increased it. The present findings suggest a decrease of capacity of adjusting feeding behavior to metabolic needs in aged rats, may be due to a deterioration of the central control of food intake.

    Background This study examined changes according to age group in the number of finishers and running times for athletes in female and male mountain ultramarathoners competing in the 78 km Swiss Alpine Marathon, the largest mountain ultramarathon in Europe and held in high alpine terrain. Methods The association between age and performance was investigated using analysis of variance and both single and multilevel regression analyses. Results Between 1998 and 2011, a total of 1,781 women and 12,198 men finished the Swiss Alpine Marathon. The number of female finishers increased (r2 = 0.64, P = 0.001), whereas the number of male finishers (r2 = 0.18, P = 0.15) showed no change. The annual top ten men became older and slower, whereas the annual top ten women became older but not slower. Regarding the number of finishers in the age groups, the number of female finishers decreased in the age group 18–24 years, whereas the number of finishers increased in the age groups 30–34, 40–44, 45–49, 50–54, 55–59, 60–64, and 70–74 years. In the age groups 25–29 and 35–39 years, the number of finishers showed no changes across the years. In the age group 70–74 years, the increase in number of finishers was linear. For all other age groups, the increase was exponential. For men, the number of finishers decreased in the age groups 18–24, 25–29, 30–34, and 35–39 years. In the age groups 40–44, 45–49, 50–54, 55–59, 60–64, 70–74, and 75–79 years, the number of finishers increased. In the age group 40–44 years, the increase was linear. For all other age groups, the increase was exponential. Female finishers in the age group 40–44 years became faster over time. For men, finishers in the age groups 18–24, 25–29, 30–34, 40–44, and 45–49 years became slower. Conclusion The number of women older than 30 years and men older than 40 years increased in the Swiss Alpine Marathon. Performance improved in women aged 40–44 years but

    Single-ventricle congenital heart disease (SVCHD) requires multiple palliative surgical procedures that leave visible surgical scars and physical deficits, which can alter body-image and self-esteem. This study aimed to compare sex and age differences in body-image, self-esteem, and body mass index (BMI) in adolescents and adults with SVCHD after surgical palliation with those of a healthy control group. Using a comparative, cross-sectional design, 54 adolescent and adult (26 male and 28 female) patients, age 15–50 years, with SVCHD were compared with 66 age-matched healthy controls. Body-image and self-esteem were measured using the Multidimensional Body-Self Relations Questionnaire–Appearance Scale and Rosenberg Self-Esteem Scale. Height and weight were collected from retrospective chart review, and BMI was calculated. Female adolescents and adult patients with SVCHD reported lower body image compared with males patients with SVCHD and healthy controls (p = 0.003). Specific areas of concern were face (p = 0.002), upper torso or chest (p = 0.002), and muscle tone (p = 0.001). Patients with SVCHD who were \\21 years of age had lower body image compared with healthy controls (p = 0.006). Self-esteem was comparable for both patients with SVCHD and healthy peers. There were no sex differences in BMI; BMI was higher in subjects[21 years of age (p = 0.01). Despite the similarities observed in self-esteem between the two groups, female patients with SVCHD\\21 years of age reported lower perceived body-image. Our findings support the need to recognize poor psychological adjustment related to low self-esteem in patients with SVCHD; female patients warrant increased scrutiny. Strategies to help patients with SVCHD cope with nonmodifiable aspects of body-image during the difficult adolescent–to–young adult years may potentially enhance self-esteem and decrease psychological distress.

    This study examined a broad variety of adverse childhood experiences in a consecutive sample of female adolescent inpatients with borderline personality disorder (BPD; n = 44) compared with a clinical control (CC; n = 47) group with mixed psychiatric diagnoses. BPD was diagnosed using a structured clinical interview; different dimensions of childhood adversity were assessed using the Childhood Experiences of Care and Abuse Questionnaire, the Parental Bonding Instrument, and the Family Assessment Device. A history of childhood adversity was significantly more common in patients with BPD than in the CC group. Using a multivariate model, sexual abuse (OR = 13.8), general family functioning (OR = 8.9), and low maternal care (OR = 7.6) were specific and independent predictors of adolescent BPD. The results increase our knowledge of the specific role of different dimensions of childhood adversity in adolescent BPD. They have important implications for prevention and early intervention as they highlight the need for specific strategies for involving the family.

    Background: Aging contains morphological and functional deterioration in biological systems. D-galactose (D-gal) generates free radicals and accelerates aging. Portulaca oleracea (Purslane) may have protective effect against oxidative stress. Objective: Purslane ethanolic extract effects were evaluated on antioxidant indices and sex hormone in D-gal aging female mice. Materials and Methods: 48 female NMRI mice (25-35 gr) were randomly divided into, 6 groups: 1- control (normal saline for 45 days), 2- Purslane (200 mg/kg for last 3 weeks), 3-D-gal (500 mg/kg for 45 days), 4-D-gal+Purslane, 5- Aging, 6-Aging+Purslane. Sex hormones, antioxidants and malondialdehyde (MDA) level of ovary and uterus were measured. Histological assessment was also done. Results: In D-gal treated and aging animals, LH and FSH levels were significantly increased (p<0.001) while estrogen and progesterone levels were significantly reduced (p<0.001) in comparison with control group. MDA contents were significantly increased in ovaries and uterus of D-gal and aging groups (p<0.01). Superoxide dismutase (SOD) (p<0.001) and catalase (p<0.01) activities were significantly decreased in both aging and D-gal treated animals. Ovarian follicles were degenerated and atrophy on uterine wall and endometrial glands was observed in D-gal and aging groups. Alteration in hormone levels, MDA contents and antioxidant activity were significantly reversed by Purslane (p<0.05). Purslane could also improve histological changes such as atrophy of endometrium. Conclusion: These findings indicate that Purslane can attenuate aging alternations induced by D-gal and aging in female reproductive system. PMID:27294220

    Women and girls’ engagement in antisocial behavior represents a psychological issue of great concern given the radiating impact that women’s antisociality can have on individuals, families, and communities. Despite its importance and relevance for psychological science, this topic has received limited attention to date and no systematic review of risk factors exists. The present paper aims to systematically review the empirical literature informing risk factors relevant to women’s antisocial behavior, with a focus on adolescence and adulthood. Primary aims are to 1) review empirical literatures on risk factors for female antisocial behavior across multiple levels of influence (e.g., person-level characteristics, risky family factors, and gender-salient contexts) and fields of study (e.g., psychology, sociology); 2) evaluate the relevance of each factor for female antisocial behavior; and 3) incorporate an analysis of how gender at both the individual and ecological level shapes pathways to antisocial behavior in women and girls. We conclude that women’s antisocial behavior is best-understood as being influenced by person-level or individual vulnerabilities, risky family factors, and exposure to gender-salient interpersonal contexts, and underscore the importance of examining women’s antisocial behavior through an expanded lens that views gender as an individual level attribute as well as a social category that organizes the social context in ways that may promote engagement in antisocial behavior. Based on the present systematic review, an integrative pathway model is proposed toward the goal of synthesizing current knowledge and generating testable hypotheses for future research.

    This cross-sectional study of urban high schools in Johannesburg, South Africa, sought to examine eating attitudes, body image and self-esteem among male adolescents (n = 391). Anthropometric measurements, Eating Attitudes Test-26 (EAT-26), Rosenberg self-esteem, body image satisfaction and perception of females were collected at age 13, 15 and 17 years. Descriptive analysis was done to describe the sample, and non-parametric Wilcoxon Mann-Whitney test was used to test for significant differences between data that were not normally distributed (EAT-26). Spearman's rank correlation coefficient analyses were conducted to test for associations between self-esteem scores and eating attitudes, body mass indices and body image satisfaction scores. To assess the differences between groups that were normally distributed chi-square tests were carried out. Ethnic differences significantly affected adolescent boys' body mass index (BMI), eating attitudes and self-esteem; White boys had higher self-esteem, BMI and normal eating attitudes than the Black boys did. BMI was positively associated with self-esteem (p = 0.01, r = 0.134) and negatively with dieting behaviour in White boys (p = 0.004, r = -0.257), and with lower EAT-26 bulimic and oral control scores in Black boys. In conclusion, the findings highlight ethnic differences and a need to better understand cultural differences that influence adolescent attitudes and behaviour.

    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.

    The effects of hormone status and age on the development of tolerance to Δ9-THC were assessed in sham-operated (intact) or ovariectomized (OVX) female rats that received either intraperitoneal saline or 5.6 mg/kg of Δ9-THC daily from postnatal day (PD) 75–180 (early adulthood onward) or PD 35–140 (adolescence onward). During this time, the four groups for each age (i.e., intact/saline, intact/THC, OVX/saline, and OVX/THC) were trained in a learning and performance procedure and dose-effect curves were established for Δ9-THC (0.56–56 mg/kg) and the cannabinoid type-1 receptor (CB1R) antagonist rimonabant (0.32–10 mg/kg). Despite the persistence of small rate-decreasing and error-increasing effects in intact and OVX females from both ages during chronic Δ9-THC, all of the Δ9-THC groups developed tolerance. However, the magnitude of tolerance, as well as the effect of hormone status, varied with the age at which chronic Δ9-THC was initiated. There was no evidence of dependence in any of the groups. Hippocampal protein expression of CB1R, AHA1 (a co-chaperone of CB1R) and HSP90β (a molecular chaperone modulated by AHA-1) was affected more by OVX than chronic Δ9-THC; striatal protein expression was not consistently affected by either manipulation. Hippocampal brain-derived neurotrophic factor expression varied with age, hormone status, and chronic treatment. Thus, hormonal status differentially affects the development of tolerance to the disruptive effects of delta-9-tetrahydrocannabinol (Δ9-THC) on learning and performance behavior in adolescent, but not adult, female rats. These factors and their interactions also differentially affect cannabinoid signaling proteins in the hippocampus and striatum, and ultimately, neural plasticity. PMID:26191005

    Adolescent females are disproportionately represented among reported cases of sexual victimization. Because sexual victimization is associated with an array of negative sequelae (e.g., depression, alcohol abuse), psychometrically sound instruments are urgently needed to assess sexual victimization or coercion. The investigation conducts a preliminary analysis of the reliability and validity of the Sexual Experiences Survey (SES) for a sample drawn from a high-risk population-African American adolescent females. Our analyses indicate good internal consistency for the SES with this sample. Convergent validity is demonstrated. Specifically, scores on the SES are associated with significantly lower levels of self-esteem and mastery, higher levels of depression, lower levels of family cohesion, higher levels of family conflict, and higher levels of using alcohol and being a smoker. Preliminary support for discriminant validity is also obtained. This study is a stepping stone for future investigations into the psychometric evaluation of the SES.
