    This article describes the life conditions of female adolescents in India and issues such as health, discrimination in nutrition and literacy, child labor, early marriage, juvenile delinquency, and violence against girls in rural areas of India. Data are obtained from interview samples conducted among 12 villages in north India. Female adolescents suffer from a variety of poverty-ridden village life conditions: caste oppression, lack of facilities, malnutrition, educational backwardness, early marriage, domestic burden, and gender neglect. Girls carry a heavy work burden. Adolescence in rural areas is marked by the onset of puberty and the thrust into adulthood. Girls have no independent authority to control their sexuality or reproduction. Girls are expected to get married and produce children. Control of female sexuality is shifted from the father to the husband. There is a strong push to marry girls soon after menstruation, due to the burden of imposing strict restrictions on female sexuality, the desire to reduce the burden of financial support, and the need to ensure social security for daughters. Girls may not go out alone or stay outside after dark. Many rural parents fear that education and freedom would ruin their daughter. Girls develop a low self-image. Rural villages have poor sanitation, toilet facilities, and drainage systems. Girls are ignorant of health and sex education and lack access to education. The neglect of female children includes malnutrition, sex bias, and early marriage. In 1981, almost 4 out of every 100 girls had to work. 5.527 million girls 5-14 years old were child laborers. Girls are veiled, footbound, circumcised, and burnt by dowry hungry in-laws. Female delinquents are subjected to sexual harassment and sometime to sexual abuse while in custody. Cows are treated better in rural India than women. Gender disparity is caused by the perpetuation of patriarchal masculine values. PMID:12158005

    2016-04-01

    Harari, Shamay-Tsoory, Ravid, and Levkovitz (2010) demonstrated a "double dissociation" in empathy in borderline personality disorder (BPD), such that BPD patients had higher affective than cognitive empathy, whereas controls exhibited the opposite pattern. Two processes that may relate to this dissociation are emotion dysregulation (ER) and hypermentalization. However, these interrelated processes have not been studied concomitantly, and the dissociation of empathy types has not been examined in adolescents with BPD. This study examined the relations between ER, hypermentalization, and cognitive and affective empathy in 252 adolescent inpatients with and without BPD. Participants completed a computerized task of hypermentalization and measures of ER and empathy. Findings only partially replicated Harari et al.'s findings, with differential performance in cognitive and affective empathy demonstrated across groups. Multivariate analyses revealed that in both groups, ER related to increased affective empathy. Hypermentalizing related to decreased cognitive empathy in BPD patients, whereas hypermentalizing did not relate to either empathy type in non-BPD patients.

    2008-08-01

    Acne vulgaris, a multifactorial condition often conferring significant psychosocial morbidity, affects an estimated 40 million people in the United States. The majority of these individuals are adolescents and young adults. The pathophysiology of the condition is still not fully known, but it is believed to be related in part to excess sebum production, follicular hyperkeratinization, microbial colonization by P acnes, and inflammation. Prior to initiating treatment in a female patient, a hyperandrogenic state must be considered and ruled out through history, physical exam, and laboratory evaluation if necessary. Treatment options are vast and include hormonal therapy among others. Hormonal therapies have long been noted to reduce acne lesions and offer a valuable adjuvant to standard therapy. Hormonal agents are thought to improve acne by blocking the androgen receptor and/or decreasing circulating androgens which leads to decreased sebum production. Hormonal treatment options include spironolactone, other antiandrogens, and oral contraceptives. The use of these agents to effectively treat acne has been demonstrated in several randomized, placebo-controlled clinical trials. Optimal results are often achieved with combination therapy with the goal of targeting multiple pathogenic pathways in acne development. PMID:18656070

    Full Text Available Exposure to stress during puberty can lead to long-term behavioral alterations in adult rodents coincident with sex steroid hormone-dependent brain remodeling and reorganization. Social isolation is a stress for social animals like mice, but little is known about the effects of such stress during adolescence on later reproductive behaviors. The present study examined sexual behavior of ovariectomized, estradiol and progesterone primed female mice that were individually housed from 25 days of age until testing at approximately 95 days, or individually housed from day 25 until day 60 (during puberty, followed by housing in social groups. Mice in these isolated groups were compared to females that were group housed throughout the experiment. Receptive sexual behaviors of females and behaviors of stimulus males were recorded. Females housed in social groups displayed greater levels of receptive behaviors in comparison to both socially isolated groups. Namely, social females had higher lordosis quotients and more often displayed stronger lordosis postures in comparison to isolated females. No differences between female groups were observed in stimulus male sexual behavior suggesting that female ’attractiveness’ was not affected by their social isolation. Females housed in social groups had fewer cells containing immunoreactive estrogen receptor (ER α in the anteroventral periventricular nucleus (AVPV and in the ventromedial nucleus of the hypothalamus (VMH than both isolated groups. These results suggest that isolation during adolescence affects female sexual behavior and re-socialization for one month in adulthood is insufficient to rescue lordosis behavior from the effects of social isolation during the pubertal period.

    This study examines individual and family characteristics of a population of 29 adolescent females charged with homicide or attempted homicide in the juvenile justice system. The purpose of this study is to contribute to the limited knowledge about adolescent females charged with homicide. Data were collected including the MAYSI-2, a risk classification instrument, and social, educational and family histories. Findings include high rates of reported substance use, delinquent peers, early indicators of mental health problems, and limited control and supervision by parents. The most common weapon used was a car and the most common victim was a known person. A comparison was conducted on girls charged with homicide during the commission of another crime or committed during a conflict. The conflict group was found to victimize friends and family significantly more often than the crime group. The crime group showed higher use of alcohol and drugs, used a gun more and had co-offenders at a higher rate. A profile was developed to describe the typical adolescent female homicide offender found in this study. Treatment recommendations and future research were discussed. PMID:17696677

    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.

    Full Text Available This article came from the monographic study “Resilience and Sexual Violence: a study of adolescents victimized by sexual abuse assistance” (MARANHÃO, 2008, in which was investigated the building resilience in victimized adolescents. Resilience is characterized as overcoming adversity, setting up as something procedural, promoted by the interaction of personal and collective protection, in particular context of risk or social vulnerability. We made the trimming about the meanings and feelings of sexual victimization within the family from the perception of adolescents between 12 and 16 years of age that received care in a Specialized Reference Social Assistance in 2010. The research is qualitative, having as theoretical-methodological referential the Historic-Cultural Theory. Data collection was used by semi-structured interview. We realize that the profile of the victims are set up by females, the beginning of sexual abuse occurred between childhood and preadolescence. The profile of perpetrators are men, adults, acting the role of the stepfather, father and uncle. Despite an abject sense, adolescents could not break the cycle of violence. Friends, extended family, and the work of professionals emerged as support for the redefinition of the abusive relationships.

    The study of body image-related problems in non-Western countries is still very limited. Thus, this study aims to identify the main influential sources and show how they affect the body image perceptions of Bangkok adolescents. The researcher recruited 400 Thai male and female adolescents in Bangkok, attending high school to freshmen level, ranging from 16-19 years, to participate in this study. Survey questionnaires were distributed to every student and follow-up interviews conducted with 40 students. The findings showed that there are eight main influential sources respectively ranked from the most influential to the least influential: magazines, television, peer group, familial, fashion trend, the opposite gender, self-realization and health knowledge. Similar to those studies conducted in Western countries, more than half of the total percentage was the influence of mass media and peer groups. Bangkok adolescents also internalized Western ideal beauty through these mass media channels. Alike studies conducted in the West, there was similarities in the process of how these influential sources affect Bangkok adolescent body image perception, with the exception of familial source. In conclusion, taking the approach of identifying the main influential sources and understanding how they affect adolescent body image perceptions can help prevent adolescents from having unhealthy views and taking risky measures toward their bodies. More studies conducted in non-Western countries are needed in order to build a cultural sensitive program, catered to the body image problems occurring in adolescents within that particular society.

    Drug abuse has been widely linked to suicide risk. We examined the factors that affect adolescent drug users' suicide attempts in South Korea. This study analyzed the data of 311 adolescents who had used drugs such as inhalants, psychotropic drugs, and marijuana (195 males and 116 females). Among 311 subjects, 109 (35.0%) had attempted suicide during the last 12 months. After adjusting for other variables, depressive mood (OR=19.79) and poly-drug use (OR=2.79), and low/middle levels of academic achievement compared with a high level (OR=3.72 and 4.38) were independently associated with increased odds of a suicide attempt, while better perceived health (OR=0.32) was independently associated with reduced odds of a suicide attempt. For adolescent drug users, preventive work should be directed toward the active treatment of drug use, depression, and physical health and reinforcing proper coping strategies for academic and other stress.

Additionally, general nutritional habits, family, friends, commercials, and availability of the food are also important for food preferences. Also, past experiences with foods are related to preferring or rejecting some foods. Socializing more with increasing age causes change in the food preferences of adolescents. Unhealthy nutrition habits form as a result of the adolescents consuming fast foods, spending time with their friends outside the house, and consuming more ready-made foods. Current developments in the food industry result in an increase in variety and consumption of snacks such as cookies, chocolate, chips, and crackers in adolescents. Considering all these, in this rewiev article, environmental and personal factors affecting food preferences have been investigated. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 121-7

    We recently observed that social interactions influence morphine responsiveness in adolescent males. Given sex-related differences in both social interactions and responses to morphine, the present study examines social influences on morphine sensitization in adolescent female mice. Four experimental groups were examined: (1) morphine-treated mice (twice daily, 10-40 mg/kg, s.c.) housed physically and visually separated from saline-treated mice ('morphine only'), (2) morphine-treated mice housed together with saline-treated mice ('morphine cage-mates (of saline)'), (3) saline-treated mice housed together with morphine-treated mice ('saline cage-mates (of morphine)'), and (4) saline-treated mice housed physically and visually separated from morphine-treated mice ('saline only'). Following the treatment period, mice were tested individually for their locomotor response to 20 mg/kg morphine (s.c.). There were no significant differences in morphine-induced hyper-locomotion between saline only and saline cage-mates (of morphine) female adolescent mice. Notably, morphine only mice exhibited significantly greater morphine sensitization as compared to morphine cage-mates (of saline). Thus, this study demonstrates social influences on morphine sensitization in adolescent females. Drug use during early adolescence is a key predictor of later drug abuse and dependence during adulthood. Thus, understanding the specific vulnerabilities to drug use in this age group may represent a first step in helping develop more effective treatment programs. PMID:20456874

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

    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.

    Full Text Available Objective. We sought to identify amount of physical activity and relationship of physical activity to glycemic control among adolescent females 11 to 19 years of age with type 1 diabetes mellitus (T1DM. We also sought to evaluate associations of age and ethnicity with physical activity levels. Research Design and Methods. Adolescent females ages 11–19 years (n=203 were recruited during their outpatient diabetes appointment. Physical activity was obtained by self-report and was categorized as the number of days subjects had accumulated 60 minutes of moderate-to-vigorous physical activity during the past 7 days and for a typical week. Results. Girls reported being physically active for at least 60 minutes per day on 2.7±2.3 days in the last week, and on 3.1±2.2 days in a typical week. A greater number of physically active days in a typical week were associated with lower A1c (P=.049 in linear regression analysis. Conclusion. Adolescent females with T1DM report exercising for at least 60 minutes about 3 days per week, which does not meet the international recommendations of 60 minutes of moderate-to-vigorous activity per day. It is particularly important that adolescent girls with T1DM be encouraged to exercise since a greater number of physically active days per week is associated with better glycemic control.

    Studies have shown impairments in cognitive function among adult patients with anorexia nervosa (AN) and affective disorders (AD). The association between cognitive dysfunctions, AN and AD as well as the specificity for these psychiatric diagnoses remains unclear. Therefore, we examined cognitive flexibility and processing speed in 47 female adolescent patients with AN, 21 female adolescent patients with unipolar affective disorders and 48 female healthy adolescents. All participants completed a neuropsychological test battery. There were no significant group differences regarding cognitive function, except for psychomotor processing speed with poorer performance in patients with AN. A further analysis revealed that all groups performed with the normal range, although patients with AN were over represented in the poorest performing quartile. We found no severe cognitive impairments in either patient group. Nevertheless, belonging to the AN group contributed significantly to poor performances in neuropsychological tasks. Therefore, we conclude that the risk for cognitive impairments is slightly higher for patients with AN. PMID:26695683

    1985-03-01

    Past research has suggested that parents may contribute to the positive development of their daughter's identity formation. Theoretical notions from both social learning and symbolic interaction indicate that parents can either facilitate or hinder positive growth. Therefore, to test the predictions that (a) more mature (moratorium and achieved) identity status parents would have daughters with more mature identities, and (b) that both positive and negative parenting styles can be detected to differentiate between less (diffused and foreclosed) and more mature identity status youths, 45 families (145 subjects) were assessed on parent-child relations and identity status formation. In contrast to much past research, parent-child relations were assessed from both the adolescents' and the parents' perspectives. The findings indicate that parental identity status formation may have an effect on the adolescent's identity formation and that parent-child relations differentiate between less and more mature female adolescent identities.

  13. Body Image and the Female Adolescent Oncology Patient.

    Burg, Alison Joy

    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.

    We investigated whether short durations (5 minutes) of exposure to distorted bodies can change subsequent perceptions of attractiveness and normality. Participants rated 110 female bodies, varying in width, on either their attractiveness or normality before and after exposure to either extremely narrow (-50% of original width in Experiments 1 and 2) or extremely wide bodies (+50% of original width in Experiment 1, and +70% of original width in Experiment 2). In both experiments, the most attractive and most normal looking bodies became significantly and substantially narrower after exposure to narrow bodies. The most normal looking body changed significantly after exposure to wide bodies, but the most attractive body did not. These results show that perceptions of body attractiveness can be influenced by experience, but that there is an asymmetry between the effects of exposure to narrow and wide bodies. We consider a possible mechanism for this unexpected asymmetry, as well as possible implications for the effects of media exposure on body-image. The most attractive body shape was consistently narrower than the most normal looking body shape. Substantial changes in what looked normal were accompanied by congruent changes in what looked attractive, suggesting that a normal or average body shape may function as a reference point against which body attractiveness is judged.

    2012-03-01

    Full Text Available 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.

    Full Text Available 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.

    2007-09-01

    Full Text Available Abstract 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.

    Full Text Available 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.

    Full Text Available Abstract Background The effectiveness of conservative treatment of scoliosis is controversial. Some studies suggest that brace is effective in stopping curve progression, whilst others did not report such an effect. The purpose of the present study was to effectiveness of Progressive Action Short Brace (PASB in the correction of thoraco-lumbar curves, in agreement with the Scoliosis Research Society (SRS Committee on Bracing and Nonoperative Management Standardisation Criteria. Methods Fifty adolescent females (mean age 11.8 ± 0.5 years with thoraco-lumbar curve and a pre-treatment Risser score ranging from 0 to 2 have been enrolled. The minimum duration of follow-up was 24 months (mean: 55.4 ± 44.5 months. Antero-posterior radiographs were used to estimate the curve magnitude (CM and the torsion of the apical vertebra (TA at 5 time points: beginning of treatment (t1, one year after the beginning of treatment (t2, intermediate time between t1 and t4 (t3, end of weaning (t4, 2-year minimum follow-up from t4 (t5. Three situations were distinguished: curve correction, curve stabilisation and curve progression. The Kruskal Wallis and Spearman Rank Correlation tests have been used as statistical tests. Results CM mean value was 29,30 ± 5,16 SD at t1 and 14,67 ± 7,65 SD at t5. TA was 12.70 ± 6,14 SD at t1 and 8,95 ± 5,82 at t5. The variation between measures of Cobb and Perdriolle degrees at t1,2,3,4,5 and between CM t5-t1 and TA t5-t1 were significantly different. Curve correction was accomplished in 94% of patients, whereas a curve stabilisation was obtained in 6% of patients. Conclusion The PASB, due to its peculiar biomechanical action on vertebral modelling, is highly effective in correcting thoraco-lumbar curves.

    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.

    2015-01-01

    This article reports the findings of a pilot study designed to: test the feasibility of implementation, assess implementation barriers, and determine the effectiveness of a modified evidence-based program designed for adolescent female offenders in a women's correctional facility in the United States. A therapeutic expressive arts behavioral program, Leadership, Education, Achievement and Development (LEAD), has been used in community settings as a health promotion program. This behavioral program was adapted to LEAD-Corrections (LEAD-C) and serves incarcerated adolescent female offenders. Results of this pilot study show that it is feasible to offer LEAD-C in a correctional setting. Positive effects were noted on session satisfaction surveys as well as formative and summative evaluations. Implementation of LEAD-C, using therapeutic expressive arts interventions, included coping strategies to help adolescents become confident and self-assured and review better choices. Adolescents were taught to utilize these learned coping strategies in their life, which may help to overcome adversity, enhance resilience, and support youth transition at the time of reentry to the community.

    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 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. PMID:19526700

    Full Text Available Abstract Background This study was developed to establish whether betaine was present in the sweat of females and to determine any correlations with other sweat components. Methods Sweat patches were placed on eight trained adolescent Highland dancers (age = 13.6 ± 2.3 yr, who then participated in a dance class for 2 hours. Patches were removed, and the sweat recovered via centrifugation. The sweat was subsequently analyzed for betaine, choline, sodium, potassium, chloride, lactate, glucose, urea and ammonia. Results Betaine was present in the sweat of all subjects (232 ± 84 μmol·L-1, which is higher than typically found in plasma. The concentration of several sweat components were correlated, in particular betaine with most other measured components. Conclusion Betaine, an osmoprotectant and methyl donor, is a component of sweat that may be lost from the body in significant amounts.

    Trauma experienced in childhood and adolescence negatively affects the development of adaptive regulation of emotions and is associated with greater symptoms of anger. Prior research has suggested that high levels of anger may impede the outcome of treatment in adults with posttraumatic stress disorder (PTSD). The current study investigated whether high levels of anger resulted in poorer treatment outcomes in adolescent girls with PTSD. Participants included 61 female adolescent survivors of sexual abuse or assault who were randomized to either prolonged exposure for adolescents (PE-A) or client-centered therapy (CCT) for traumatized children for 8-14 weekly sessions. Participants were followed for 12 months posttreatment. High levels of state anger at baseline were associated with less improvement in PTSD symptoms in the CCT group than the PE-A group (d = 0.62). The moderating effects of state anger on improvement in PTSD symptoms was significant with emotion regulation difficulties, which may underlie anger symptoms (d = 0.58) in the model. The results of this study suggessted that high state anger was less of an impediment to treatment of PTSD for those receiving PE-A than those receiving less differentiated approaches such as CCT.

    The development of reward-based learning and decision-making, and the neural circuitry underlying these processes, appears to be influenced negatively by adverse child-rearing environments characterized by abuse and other forms of maltreatment. No research to-date has investigated whether normative variations in the child-rearing environment have effects on adolescent brain structure. We examined whether normative variations in maternal responses to adolescents' positive affective behavior were associated with morphometric measures of the adolescents' affective neural circuitry, namely the amygdala, orbitofrontal cortex (OFC), and anterior cingulate cortex (ACC). Healthy adolescents (N = 113) participated in laboratory-based interaction tasks with their mothers, and underwent high-resolution (3T) structural magnetic resonance imaging (MRI). The mother-adolescent interactions included a pleasant event-planning interaction (EPI) and a conflictual problem-solving interaction (PSI). Adolescents, whose mothers displayed more punishing responses to their positive affective behavior during both tasks, and only during the PSI, had larger left dorsal ACC and bilateral OFC volumes, respectively. In addition, boys whose mothers evidenced this pattern of behavior during the EPI had larger right amygdala volumes. These results suggest that normative variations in maternal responses to affective behavior are associated with the structural characteristics of adolescents' affective neural circuitry, which may have implications for the development of their social, cognitive and affective functioning.

    Initial antidepressant treatment can paradoxically worsen symptoms in depressed adolescents by undetermined mechanisms. Interestingly, antidepressants modulate GABAA receptors, which mediate paradoxical effects of other therapeutic drugs, particularly in females. Although the neuroanatomic site of action for this paradox is unknown, elevated GABAA receptor signaling in the nucleus accumbens can disrupt motivation. We assessed fluoxetine's effects on motivated behaviors in pubescent female hamsters - anhedonia in the reward investigational preference (RIP) test as well as anxiety in the anxiety-related feeding/exploration conflict (AFEC) test. We also assessed accumbal signaling by RT-PCR and electrophysiology. Fluoxetine initially worsened motivated behaviors at puberty, relative to adulthood. It also failed to improve these behaviors as pubescent hamsters transitioned into adulthood. Low accumbal mRNA levels of multiple GABAA receptor subunits and GABA-synthesizing enzyme, GAD67, assessed by RT-PCR, suggested low GABAergic tone at puberty. Nonetheless, rapid fluoxetine-induced reductions of α5GABAA receptor and BDNF mRNA levels at puberty were consistent with age-related differences in GABAergic responses to fluoxetine and disruption of the motivational state. Whole-cell patch clamping of accumbal slices also suggested low GABAergic tone by the low amplitude of miniature inhibitory postsynaptic currents (mIPSCs) at puberty. It also confirmed age-related differences in GABAergic responses to fluoxetine. Specifically, fluoxetine potentiated mIPSC amplitude and frequency at puberty, but attenuated the amplitude during adulthood. These results implicate GABAergic tone and GABAA receptor plasticity in adverse motivational responses and resistance to fluoxetine during adolescence. PMID:27068049

  5. Musculoskeletal pain syndromes that affect adolescents.

    Szer, I S

    1996-07-01

    Musculoskeletal pain is one of the most common pains of adolescence, along with headache and abdominal pain, and arthralgia is the single most common reason for referral to the pediatric rheumatologist. Not surprisingly, the pediatric rheumatologist is frequently called to distinguish organic from functional symptoms. During the past decade, the pediatric rheumatology community has been evaluating increasing numbers of adolescents and preadolescents who experience musculoskeletal symptoms presumably as a defense against emotional stress from achievement either in academic work or in sports. To complicate the challenge further, coexistent organic and psychologic disturbance is not rare. Clearly, organic illness does not protect a patient from emotional plan, and it may be most difficult to differentiate nonorganic pain in a patient with a known organic illness. Conversely, adolescents with organic illness may use their disease for secondary gain. Fear of misdiagnosis of physical illness as psychiatric and the notion that all of the patient's complaints should be explained by a unifying diagnosis cause diagnostic error in both psychogenic illness with physical manifestations and physical illness with psychogenic symptoms.

    It was recently observed that dehydration causes shrinkage of brain tissue and an associated increase in ventricular volume. Negative effects of dehydration on cognitive performance have been shown in some but not all studies, and it has also been reported that an increased perceived effort may be required following dehydration. However, the effects of dehydration on brain function are unknown. We investigated this question using functional magnetic resonance imaging (fMRI) in 10 healthy adolescents (mean age = 16.8, five females). Each subject completed a thermal exercise protocol and nonthermal exercise control condition in a cross-over repeated measures design. Subjects lost more weight via perspiration in the thermal exercise versus the control condition (P Dehydration following the thermal exercise protocol led to a significantly stronger increase in fronto-parietal blood-oxygen-level-dependent (BOLD) response during an executive function task (Tower of London) than the control condition, whereas cerebral perfusion during rest was not affected. The increase in BOLD response after dehydration was not paralleled by a change in cognitive performance, suggesting an inefficient use of brain metabolic activity following dehydration. This pattern indicates that participants exerted a higher level of neuronal activity in order to achieve the same performance level. Given the limited availability of brain metabolic resources, these findings suggest that prolonged states of reduced water intake may adversely impact executive functions such as planning and visuo-spatial processing.

  7. On a disturbance of affectivity in schizophrenic adolescents: implications for affect theory.

    1980-01-01

    As recently as 1969 Loeb stated, "Not only has adolescent schizophrenia been largely ignored by the clinician and research worker but until recent years the entire subject of adolescence had received scant attention" (p. 462). Since that time, a number of investigators have attended to similarities and differences between the schizophrenic syndrome, as a whole, and schizophrenia as it appears in adolescence. One of the findings that has been alluded to by some authors concerns the notion that affect is less severely disturbed, especially in the dimension of affective responsiveness, in adolescent schizophrenics (Sands, 1956). Observations by the author and others suggest that greater attention be paid to the variety of affectivity to delineate this area of symptomatology, which both Kraepelin and Bleuler considered so fundamental and typical in their designations of dementia praecox and schizophrenia. Indeed the purpose of this study concerns the description and dynamic understanding of a typical disturbance of affectivity in adolescent schizophrenics. This disturbance is characterized by a quality of affective communication in which the patient relates to the people around him in a superficial, socially acceptable, receptionist-like manner which induces in the observer the impression that the individual's genuine feelings are not prominent. For want of a better term, we may designate this affective state "airline-hostess affectivity" (A.H.A.). The disturbance is not exclusive to adolescent schizophrenics but can also be observed in young adults too before a phase of chronic adaptation to the schizophrenic process. PMID:7369002

  8. Weight Misperceptions and Racial and Ethnic Disparities in Adolescent Female Body Mass Index

    Full Text Available 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.

    The goal of the current investigation was to address whether affective decision making would serve as a unique neuropsychological marker to predict drinking behaviors among adolescents. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu city, China. In their 10th grade (ages 15-16), these adolescents were tested for their affective decision-making ability using the Iowa Gambling Task (IGT) and working memory capacity using the Self-Ordered Pointing Test. Self-report questionnaires were used to assess academic performance and drinking behaviors. At 1-year follow-up, questionnaires were completed to assess drinking behaviors, and the UPPS Impulsive Behavior Scale was used to examine four dimensions of impulsivity: urgency, lack of premeditation, lack of perseverance, and sensation seeking. Results indicated that those adolescents who progressed to binge drinking or exhibited consistent binge drinking not only performed poorly on the IGT but also scored significantly higher in urgency compared to those who never or occasionally drank. Moreover, better IGT scores predicted fewer drinking problems and fewer drinks 1 year later after controlling for demographic variables, the previous drinking behaviors, working memory, and impulsivity. These findings suggest that deficits in affective decision making may be important independent determinants of compulsive drinking and potentially addictive behavior in adolescents. PMID:19573273

    This study aimed to assess the extent, patterns, and predictors of feelings of body dissatisfaction experienced by female German adolescents. Using 3D-avatar software, a sample population of 144 girls between 14 and 17 years of age was asked to estimate their actual body image, their desired body image (individual ideal), and the body image they believed their parents and their best female friend considered to be the ideal body image for them. The participants estimated their actual body mass index (BMI) to be 18.82 ± 3.01. The individual ideal body shape reported was significantly thinner, with a BMI score of 16.84 ± 2.51. Given a girl who stands 1.65 m and weighs 55 kg, this corresponds to a difference in weight of about 5.5 kg. After adjustment for the participant's self-reported BMI, participating in an esthetic sport was correlated with a significantly lower body dissatisfaction. Conversely, low socio-economic status and the amount of time spent watching TV was correlated with a significantly higher body dissatisfaction. Negative body image-related comments made by parents were significantly associated with body dissatisfaction. The girls who participated in this study would like to be an average of 1.97 BMI units thinner. The findings presented here suggest that future intervention measures should focus on the risk groups of physically inactive girls, those who smoke, and those with a lower social status and high rates of TV consumption. Intervention measures would be especially effective in German schools which offer lower education levels and should include the pupils' parents, who should be informed about the negative effects weight- and diet-related comments have on their children's body images.

It is imperative to address the intersection of these two urgent public health issues, particularly as these affect African-American adolescent girls. This study assessed the prevalence of rape victimization (RV among a sample of African-American adolescent females and examined the extent to which participants with a history of RV engage in STI/HIV associated risk behaviors over a 12-month time period.Methods: Three hundred sixty-seven African-American adolescent females ages 15-21, seeking sexual health services at three local teenager-oriented community health agencies in an urban area of the Southeastern United States, participated in this study. Participants were asked to complete an audio computer-assisted self-interview (ACASI at baseline, six- and 12-month follow-up. We assessed sociodemographics, history of RV and sexual practices. At baseline, participants indicating they had experienced forced sex were classified as having a history of RV.Results: Twenty-five percent of participants reported a history of RV at baseline. At six- and 12-months, victims of RV had significantly lower proportions of condom-protected sex (p=.008, higher frequency of sex while intoxicated (p=.005, more inconsistent condom use (p=.008, less condom use at last sex (p=.017, and more sex partners (p=.0001 than non-RV victims. Over the 12-month follow-up period, of those who did not report RV at baseline, 9.5% reported that they too had experienced RV at some point during the 12-month time frame.Conclusion: African-American adolescent females who experience RV are engaging in more risky sexual behaviors over time than non-RV girls, thereby placing themselves at higher risk for contracting STIs. In light of the results from this unique longitudinal study, we discuss considerations for

    Recent research has highlighted the presence of Young's Early Maladaptive Schemas (EMSs) in individuals with an eating disorder (ED). This study assessed the EMSs reported by adolescent females with Anorexia Nervosa (AN) compared with a community group. Thirty-six adolescent females diagnosed with AN or subthreshold AN and 111 female secondary school students completed a questionnaire that included the Young Schema Questionnaire, the Behavior Assessment System for Children Self-report of Personality, and the Eating Disorder Screen for Primary Care. Two independent AN subtypes and two community subtypes were derived from responses to the questionnaire, and significant differences between the four comparison groups were found. High Pathology AN participants reported the highest level of psychological maladjustment. Social Isolation and Emotional Inhibition appeared to be most characteristic of adolescent AN in this sample. The results suggest that EMSs may require attention in the treatment of AN in adolescent females, and that different AN subtypes may require individualized treatment approaches. PMID:25464069

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.

In the study, descriptive method was employed. The sample group of the study is 300 secondary school female students between 16-18 years of age. Body Cathexis Scale and Coopersmith Self-Esteem Inventory were applied to the adolescents in the sample group. Results have shown that there are a high level, negative and significant relationship between the body image and self-esteem (r=-0,365, p<.01 of female adolescents. Findings also illustrate that an increase in female adolescents’ content with their body image leads to an increase in their self-esteem. Results of the study revealed that female adolescents with positive body image have a high level of self-esteem and so female adolescents with negative body image have a low level of self-esteem. In this respect, in this study, the importance of female adolescents’ realistic appreciation concerned with their body image is discussed.

    1997-01-01

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

    Full Text Available Introduction: Body dysmorphic disorder is one of the common disorders in which adolescents give excessive attention to their appearances. In fact, it may causes disruptions in adolescents' individual and social life. Therefore, this study aimed to investigate the prevalence of body dysmorphic disorder in female adolescents of Yazd. Method: In this cross-sectional study, the population consisted of all high school female students of Yazd (N= 10737 in 2012-2013, among which 371 students were selected as the study sample by using Cochran formula and cluster sampling method. Moreover, the participants completed a series of demographic questions as well as the questionnaire of Yale-Brown Obsessive Compulsive Scale-Body Dysmorphic Disorder (Y-BOCS-BDD. Results: The findings revealed that 41% of sample were reported to have unusual concern about appearance and body shape in range of low to very severe. As a matter of fact, most of them experienced moderate severity and 7.1% showed severe body dysmorphic disorder that required immediate psychological intervention. The prevalence in female adolescents was estimated as 7.1% and most prevalent age of suffering was 17. Conclusion: In this research, it was endeavored to provide a more realistic image of body dysmorphic disorder in Yazd adolescents by utilizing a precise methodology. Considering the high prevalence of this disorder in female adolescents and its adverse consequences, some programs are recommended to be applied for diagnosis and early treatment of body dysmorphic disorder to promote adolescents mental health.

    Pelvic tumors in adolescent females are very uncommon. While the most common presentation is pelvic discomfort, we report the case of a 14-year-old female presenting with menorrhagia which is an unusual initial complaint for a large pelvic tumor. Adolescent females who present with heavy menstrual bleeding initially undergo assessment to rule out a bleeding disorder. In this case, careful history and physical examination helped in making a quick diagnosis and management. Ultrasound of abdomen showed a huge cystic mass due to serous cystadenoma of the ovary.

    2015-02-01

    This study investigated the relationship between stress and body satisfaction in adolescence. A sample consisting of 515 adolescents aged 12-16 years completed a series of self-report questionnaires assessing general and specific aspects of adolescent stress, body satisfaction and the psychological constructs of self-esteem, depressive symptoms and body importance. Results revealed a significant association between higher body dissatisfaction and higher ratings of peer stress, lower self-esteem and greater body importance for female and male adolescents. These findings suggest that adolescent stress relates to satisfaction with the body and that this stress is specifically focused on the peer environment for both genders during adolescence. This may have implications for intervention programmes aimed at improving body satisfaction, suggesting that the inclusion of stress management training in these programmes could specifically focus on difficulties within the peer domain.

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

    Full Text Available Positive (PA and negative affect (NA are two separate systems markers of subjective well-being and measures of the state depression (low PA combined with high NA. The present study investigated differences in temperament, character, locus of control, and depressive symptoms (sleep quality, stress, and lack of energy between affective profiles in an adolescent sample. Participants (=304 were categorized into four affective profiles: “self-fulfilling” (high PA, low NA, “high affective” (high PA, high NA, “low affective” (low PA, low NA, and “self-destructive” (low PA, high NA. Personality was measured by the Temperament and Character Inventory and affective profiles by the Positive Affect and Negative Affect Schedule. The “self-fulfilling” profile was characterized by, compared to the other affective profiles, higher levels of sleep quality, less stress and more energy and also higher levels of persistence and a mature character (i.e., high scores in self-directedness and cooperativeness. “Self-destructive” adolescents reported higher levels of external locus of control, high scores in harm avoidance and reward dependence combined with less mature character. The results identify the importance of character maturity in well-being and suggest that depressive state can be positively influenced by promoting positive emotions which appears to be achieved by character development.

    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. PMID:23837266

    Full Text Available INTRODUCTION/OBJECTIVES: The pattern of drug use among adolescents is not well known. Epidemiologic studies have reported no difference in the prevalence of drug use between genders. The present study wanted to assess the difference in drug use between genders in adolescents. The following variables were assessed: gender ratio of those looking for treatment; age they looked for treatment; age of the first drug use; substances used; with whom they first used drugs; pattern of drug use; possibly-related behavior (illegal acts, problems with the police and school delay. METHODS: Medical records of adolescents treated between 1993 and 2000 in a public medical center of the city São Paulo were analyzed. RESULTS: One-hundred and five medical records of adolescents aged 10 to 17 were reviewed. There were no differences between genders according to: age they looked for treatment; age of the first drug use; substances used; and illegal acts. There was a higher prevalence of male adolescents regarding to problems with the police and school delay. CONCLUSIONS: Data suggest that the behavioral consequences of drug use in female adolescents are less evident than in male adolescents, what could explain the lower frequency in which female adolescents had specialized treatment.

    Full Text Available Abstract Background Adolescents rarely seek psychiatric help; they even hesitate to disclose their feelings to their parents. However; the adolescents especially the females experience depressive symptoms more frequently than general population. Do they experience classic depressive symptoms? Are there symptoms specific to this subpopulation? Aim of the study Through this study, the authors aimed to estimate the prevalence of depressive disorders in Egyptian adolescent female students. They also expected a characteristic profile of symptoms for the adolescent females. However available literature provides no guidance in the description of this profile of symptoms. Methods A number of 602 adolescent females were interviewed, and subjected to General Health Questionnaire (GHQ; Children Depression Inventory (CDI, Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I, then Hamilton Rating Scale for Depression (Ham-D. Results were analyzed by the use of SPSS-15. Results The study revealed the prevalence of depression in the sample of the study to be 15.3% (measured by CDI, and 13.3% (measured by SCID-I. Fatigue was the most common presenting depressive symptom (81.3%, in addition to other emotional, cognitive and physiological symptoms. Suicidal ideations were the most common suicidal symptoms in depressed adolescent females (20%, with 2.5% serious suicidal attempts. Conclusions The somatic symptoms were by far the most common presenting symptom for female adolescents suffering from depressive disorders. Depressive phenomena including unexplained fatigue, decreased energy, psychomotor changes, lack of concentration, weight changes and suicidal ideations may be the presenting complaints instead of the classic sad mood.

    The study examines the social and cultural experiences of adolescent female belonging to various south Asian immigrant groups in Canada. Applying qualitative research method, the authors interviewed 22 adolescent girls of Indian, Pakistani and Bangladeshi origin in Montreal. Like other immigrant communities, south Asian families undergo acculturation stress. South Asians tend to integrate secular European cultural elements with their culture; however, family and community structure remain male dominated. The study showed that gender roles were maintained through gender segregation, control over social activities of girls and arranged marriage. Interviewees felt that their parents and communities have more stringent rules for female socialization than any other community in Canada. The study also found that adolescent girls perceived high social cost attached to protest and dissent, therefore, they accept prevalent conditions and expect to change social situation gradually. Some adolescents undergo stress resulting in behavioral problems.

    2002-11-01

    A four-page survey was administered to 535 adolescents at two single-sex (one male, one female) high schools in Cincinnati, Ohio, to examine whether perceptions of physical activity differed by gender. More specifically, the survey assessed perceived cues, benefits, and barriers to exercising. Results indicated that the most helpful cue to physical activity for both female and male students was "having a friend to exercise with." The most commonly reported benefit of exercising among females was "to stay in shape," whereas the most commonly reported benefit to exercising among males was "to become strong." Among females, the most common barrier to exercising was "having no time to exercise," whereas males were most likely to report "wanting to do other things with my time." Multivariate analyses of covariance revealed that perceived cues, benefits, and barriers to physical activity differed significantly based on gender. Recommendations on specific strategies to increasing male and female adolescent physical activity levels are offered. PMID:12557633

    2016-01-01

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

    African American female adolescents have a disproportionate risk of sexually transmitted infections (STIs) and other adverse sexual health outcomes. Both alcohol and marijuana use have been shown to predict sexual risk among young African American women. However, no studies have attempted to differentiate alcohol and marijuana typologies use as predictors of sexual risk outcomes exclusively among adolescents who use these substances. This study compared recent alcohol and/or marijuana use as predictors of sexual risk outcomes over 18 months among 182 African American female adolescents. African American females (14-20 years) completed interviews at baseline, 6-, 12-, and 18-months. At each assessment, pregnancy testing was conducted and self-collected vaginal swab specimens were assayed for Trichomonas vaginalis, Chlamydia trachomatis, and Neisseria gonorrhoeae using DNA amplification. Logistic subject-specific random-intercept models compared sexual risk outcomes during follow-up among adolescents who reported recent use of alcohol only (AO), marijuana only (MO) or both substances (A + M) at the baseline assessment. Relative to baseline AO use, baseline MO use predicted condom non-use at last sex. Relative to AO use, A + M use predicted pregnancy. Relative to MO use, A + M use predicted pregnancy and acquisition of T. vaginalis and any STI. The results suggest that African American female adolescents who use A + M may represent a priority population for STI, HIV, and pregnancy prevention efforts.

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

    Atwell, Ashley; Wagner, William E

    2015-06-01

    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. PMID:25857998

    2014-06-01

    Full Text Available 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.

    Attachment behaviors play a critical role in regulating emotion within the context of close relationships, and attachment theory is currently used to inform evidence-based practice in the areas of adolescent health and social care. This study investigated the association between female adolescents' interview-based attachment behaviors and two markers of hypothalamic-pituitary-adrenal axis activity: cortisol and dehydroepiandrosterone (DHEA). Unlike the classic stress hormone cortisol, there is very limited investigation of DHEA-a quintessential developmental hormone-in relation to attachment, especially in adolescents. Fifty-five healthy females mean age 14.36 (±2.41) years participated in the attachment style interview. A smaller cortisol awakening response was related to anxious attachment attitudes, including more fear of rejection, whereas greater morning basal DHEA secretion was only predicted by lower levels of reported confiding in one's mother. These attachment-hormone relationships may be developmental markers in females, as they were independent of menarche status. These findings highlight that the normative shifts occurring in attachment to caregivers around adolescence are reflected in adolescents' biological stress regulation. We discuss how studying these shifts can be informed by evolutionary-developmental theory.

    Human papillomavirus (HPV) vaccination coverage among adolescent females is well below national public health goals. Many known barriers to HPV vaccine receipt can be addressed in parent-physician conversations. This study sought to explore parent experiences and attitudes related to HPV vaccination of adolescent girls, focused on interactions with providers. We conducted a cross-sectional survey of parents using a nationally representative online panel. Among parents with ≥1 daughter aged 11 to 17 years, provider recommendations for HPV vaccine and specified age to begin the HPV vaccine series were associated with HPV vaccine status. Parents who reported their daughters were unlikely to complete the HPV series were more likely to have had no discussion of HPV vaccine with the provider. Efforts to increase HPV vaccination rates among adolescent females should continue to focus on improving provider discussion of HPV vaccine. PMID:26450982

    2012-01-01

    Despite the growing number of epidemiologic studies about the prevalence of non-suicidal self-injury (NSSI), little knowledge exists regarding the way adolescents view NSSI, whether differences in the attitudes towards NSSI between affected and non-affected adolescents exist and whether the acquaintance with adolescents engaging in NSSI influence one's attitudes towards self-injury? In an epidemiological study of non-suicidal self-injury, we assessed the attitudes of 447 ninth grade students (age 15 years SD = 0.7, 52% male) NSSI using a self-constructed questionnaire with three factors. Sixty one (13.6%) pupils reported that they had intentionally injured themselves once in their life time. 43% (n = 179) indicated that they discuss the topic with others, though over half of these pupils 54% (n = 98) stated feeling burdened by discussions with friends affected by NSSI. Comparisons between affected and non-affected adolescents revealed that adolescents who had never exhibited NSSI tend to believe that NSSI is mostly interpersonally motivated. Moreover, the adolescents affected by NSSI assessed the emotional reaction as more appropriate than non-affected adolescents. This should be considered in the design and refinement of inpatient treatment concepts. Our results suggest focusing on intrapersonal motives in psychotherapeutic sessions and reducing interpersonal motives for self-injurious behaviour through the establishment of clear and transparent milieu therapeutic structural conditions.

    Data from both human and animal studies suggest that exposure to stressful life events at neonatal stages may increase the risk of psychopathology at adulthood. In particular, early maternal deprivation, 24 h at postnatal day (pnd) 9, has been associated with persistent neurobehavioural changes similar to those present in developmental psychopathologies such as depression and schizophrenic-related disorders. Most neuropsychiatric disorders first appear during adolescence, however, the effects of MD on adolescent animals' brain and behaviour have been scarcely explored. In the present study, we aimed to investigate the emotional and cognitive consequences of MD in adolescent male and female rats, as well as possible underlying neurobiological mechanisms within frontal cortex and hippocampus. Animals were exposed to a battery of behavioural tasks, from pnd 35 to 42, to evaluate cognitive [spontaneous alternation task (SAT) and novel object test (NOT)] and anxiety-related responses [elevated plus maze (EPM)] during adolescence. Changes in neuronal and glial cells, alterations in synaptic plasticity as well as modifications in cannabinoid receptor expression were investigated in a parallel group of control and adolescent (pnd 40) male and female animals. Notably, MD induced a significant impairment in recognition memory exclusively among females. A generalized decrease in NeuN expression was found in MD animals, together with an increase in hippocampal glial fibrillar acidic protein (GFAP) expression exclusively among MD adolescent males. In addition, MD induced in the frontal cortex and hippocampus of male and female adolescent rats a significant reduction in brain derived neurotrophic factor (BDNF) and postsynaptic density (PSD95) levels, together with a decrease in synaptophysin in frontal cortex and neural cell adhesion molecule (NCAM) in hippocampus. MD induced, in animals of both sexes, a significant reduction in CB1R expression, but an increase in CB2R that was

    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. PMID:22940911

    Knee injuries are common in adolescent female football. Self-reported previous knee injury and low Knee injury and Osteoarthritis Outcome Score (KOOS) are proposed to predict future knee injuries, but evidence regarding this in adolescent female football is scarce. The aim of this study was to investigate self-reported previous knee injury and low KOOS subscale score as risk factors for future knee injuries in adolescent female football. A sample of 326 adolescent female football players, aged 15-18, without knee injury at baseline, were included. Data on self-reported previous knee injury and KOOS questionnaires were collected at baseline. Time-loss knee injuries and football exposures were reported weekly by answers to standardized text-message questions, followed by injury telephone interviews.

    Full Text Available Abstract Elite adolescent figure skaters must accommodate both the physical demands of competitive training and the accelerated rate of bone growth that is associated with adolescence, in this sport that emphasizes leanness. Although, these athletes apparently have sufficient osteogenic stimuli to mitigate the effects of possible low energy availability on bone health, the extent or magnitude of bone accrual also varies with training effects, which differ among skater disciplines. Purpose We studied differences in total and regional bone mineral density in 36 nationally ranked skaters among 3 skater disciplines: single, pairs, and dancers. Methods Bone mineral density (BMD of the total body and its regions was measured by dual energy x-ray absorptiometry (DXA. Values for total body, spine, pelvis and leg were entered into a statistical mixed regression model to identify the effect of skater discipline on bone mineralization while controlling for energy, vitamin D, and calcium intake. Results The skaters had a mean body mass index of 19.8 ± 2.1 and % fat mass of 19.2 ± 5.8. After controlling for dietary intakes of energy, calcium, and vitamin D, there was a significant relationship between skater discipline and BMD (p = 0.002, with single skaters having greater BMD in the total body, legs, and pelvis than ice dancers (p  Conclusions Single and pair skaters have greater BMD than ice dancers. The osteogenic effect of physical training is most apparent in single skaters, particularly in the bone loading sites of the leg and pelvis.

    Data suggest that depressed affect and dietary restraint are related to disinhibited eating patterns in children and adults. Yet, experimental research has not determined to what extent depressed affect acutely affects eating in the absence of physiological hunger (EAH) in adolescents. In the current between-subjects experimental study, we measured EAH in 182 adolescent (13-17 y) girls (65%) and boys as ad libitum palatable snack food intake after youth ate to satiety from a buffet meal. Just prior to EAH, participants were randomly assigned to view either a sad or neutral film clip. Dietary restraint was measured with the Eating Disorder Examination. Adolescents who viewed the sad film clip reported small but significant increases in state depressed affect relative to adolescents who viewed the neutral film clip (p affective state and dietary restraint, is required to elucidate how state affect may interact with dietary restraint to influence EAH during adolescence.

    We examined the associations between observed expressions of positive and negative emotions during conflict discussions and depressive symptoms during a 2-year period in a sample of 160 adolescents in 80 romantic relationships (M age = 15.48, SD = 1.16). Conflict discussions were coded using the 10-code Specific Affect Coding System. Depressive symptoms were assessed at the time of the observed conflict discussions (Time 1) and 2 years later (Time 2). Data were analyzed using actor-partner interdependence models. Girls' expression of both positive and negative emotions at T1 was related to their own depressive symptoms at T2 (actor effect). Boys' positive emotions and negative emotions (actor effect) and girls' negative emotions (partner effect) were related to boys' depressive symptoms at T2. Contrary to expectation, relationship break-up and relationship satisfaction were unrelated to changes in depressive symptoms or expression of negative or positive emotion during conflict discussion. These findings underscore the unique quality of adolescent romantic relationships and suggest new directions in the study of the link between mental health and romantic involvement in adolescence.

    Full Text Available 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.

    A study of 152 adolescents enrolled in school-based programs for pregnant and parenting youth in Colorado in 1987-88 found no differences in overall stress levels between these two groups; however, salient predictors of stressful life events for pregnant teens were not the same as those for teen mothers. The mean age of study subjects was 16.5 years (range 14-19 years); most were living with a parent rather than the child's father. The dependent variable, level of stress, was measured through use of an abbreviated Life Events Questionnaire. Independent variables were assessed through administration of the Inventory of Social Supportive Behaviors, Rosenberg Self-Esteem Scale, and the Adolescent Coping Orientation for Problem Experiences scale. Of the 5 sources of stress measured (family, accidents, autonomy, deviance, relocation, and distress), only stress related to accidents differed significantly between pregnant and parenting adolescents. For pregnant adolescents, self-esteem was the only significant predictor of the overall level of stress; among parents, the only significant predictor was objective social support. Among adolescents, self-esteem was associated with more frequent use of social support and coping strategies. For parenting adolescents, self-esteem was correlated with the frequency of use of social support, satisfaction resulting from such use, and frequent use of coping strategies. Overall, the independent variables of social support, self-esteem, coping, and age were stronger predictors of stress in pregnant than in parenting adolescent females. This finding suggests that parenting teens may have successfully negotiated the multiple transitions involved in this new stage of the life-cycle. An important implication of this study is the need to design separate counseling components of school-based programs for pregnant versus parenting adolescents rather than to use a single curriculum.

    Full Text Available Background: The pattern of Islamic fasting differs from other forms of fasting, therefore its effecton health also differs. This research studies the effect of Islamic fasting on gonadotropin hormonesaround the time of the ovulatory cycle and ovulation.Materials and Methods: This self-controlled study was performed on 24 adult females. Bloodsampling was performed during Ramadan and two months later to determine the levels of folliclestimulating hormone (FSH, luteinizing hormone (LH, estrogen and progesterone. Ultrasonographywas done in order to detect ovulation and the results were compared.Results: The mean values of FSH, LH and estrogen during the 14th day of menstruation werecomparable with non-fasting values. There was no significant difference in ovulation.Conclusion: Islamic fasting causes neither significant variation in hormone secretion aroundovulation nor does it influence the occurrence of ovulation.

    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, ele...

    A manual for a disorder oriented psychodynamic treatment of bulimia nevosa and atypical bulimia nervosa of female adolescents and young adults is presented. This manual is applied in a therapy project, which started in 2007. The work on conflicts and structural dysfunctions is meant to lead to the removal or alleviation of the symptoms and an improvement of eating behavior and body image. The bulimic symptoms are contextualized and focussed according to the conflicts and ego-structural deficits of the patients. Typical patterns of interpersonal relationships, transference, conflict, defence and structural problems as well as therapeutic steps are described. The typical psychosocial situation of female adolescence and young adult age is taken into account. Special emphasis is laid on the limitedness of the therapy to 60 sessions and the active structuring of the final phase of he therapy by the therapist. PMID:24693801

    This qualitative study examines the self-reported reasons for fighting among female adolescents (N = 72). Data are drawn from brief intervention sessions addressing violent behavior and alcohol use. Young women age 14 to 18 (Mean = 16) were recruited in an urban emergency department (58.3% African American/Black, 31.9% White, and 9.7% other races/ethnicities). Participants identified multiple reasons that they engage in fights including self-protection/self-defense, enhancing social status and respect, safety (e.g., preventing future fights or sexual assaults), revenge/retaliation, social motivations (e.g., defending family or friends, fighting over romantic interests), coping, and enjoyment. Results provide insight into opportunities and challenges in developing interventions addressing aggression among female adolescents. PMID:27018828

    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. PMID:26826605

    For women, the nature and range of experiences during the high school years take on special significance, since it is during this period that they usually weigh their various roles and adjust their levels of aspirations accordingly. If the high school environment is successful in reducing the discrepancy between what are often viewed as conflicting roles, adolescent females may place greater emphasis on achievement. It is within this context that the present paper explored the differential benefits of single-sex and coeducational schooling. The issue explored is not whether one is preferable for females; rather, the concern here is how each of these settings influences both achievement and personal fulfillment. PMID:1414569

    Female remating in target pest species can affect the efficacy of control methods such as the Sterile Insect Technique (SIT) but very little is known about the postcopulatory mating behavior of these pests. In this study, we investigated the remating behavior of female Anastrepha serpentina (Diptera: Tephritidae), an oligophagous pest of Sapotaceae. First, we tested how long the sexual refractory period of females lasted after an initial mating. Second, we tested the effect of male and female sterility, female ovipositing opportunities and male density on female propensity to remate. Lastly, we tested if the amount of sperm stored by females was correlated to the likelihood of females to remate. We found that receptivity of mass-reared A. serpentina females had a bimodal response, with up to 16% of mass-reared A. serpentina females remating five days after the initial copulation, decreasing to 2% at 10 and 15 days and increasing to 13% after 20 days. Compared to fertile males, sterile males were less likely to mate and less likely to inhibit females from remating. Copula duration of sterile males was shorter compared to fertile males. Remating females were less likely to mate with a sterile male as a second mate. Sterile females were less likely to mate or remate compared to fertile females. Opportunity to oviposit and male density had no effect on female remating probability. Sperm numbers were not correlated with female likelihood to remate. Information on the post-copulatory behavior of mass-reared A. serpentina will aid fruit fly managers in improving the quality of sterile males. We discuss our results in terms of the differences this species presents in female remating behavior compared to other tephritids. PMID:26616467

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

    Full Text Available Abstract 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.

We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs.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.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%.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.

    Abstract Background Adolescent females have been highlighted as a particularly sedentary population and the possible negative effects of a sedentary lifestyle are being uncovered. However, much of the past sedentary research is based on self-report or uses indirect methods to quantity sedentary time. Total time spent sedentary and the possible intricate sedentary patterns of adolescent females have not been described using objective and direct measure of body inclination. The objectives of this article are to examine the sedentary levels and patterns of a group of adolescent females using the ActivPAL™ and to highlight possible differences in sedentary levels and patterns across the week and within the school day. A full methodological description of how the data was analyzed is also presented. Methods One hundred and eleven adolescent females, age 15-18 yrs, were recruited from urban and rural areas in the Republic of Ireland. Participants wore an ActivPAL physical activity monitor for a 7.5 day period. The ActivPAL directly reports total time spent sitting\\/lying every 15 seconds and accumulation (frequency and duration) of sedentary activity was examined using a customized MATLAB ® computer software programme. Results While no significant difference was found in the total time spent sitting\\/lying over the full 24 hour day between weekday and weekend day (18.8 vs. 18.9 hours; p = .911), significantly more sedentary bouts of 1 to 5 minutes and 21 to 40 minutes in duration were accumulated on weekdays compared to weekend days (p < .001). The mean length of each sedentary bout was also longer (9.8 vs. 8.8 minutes; p < .001). When school hours (9 am-3 pm) and after school hours (4 pm-10 pm) were compared, there was no difference in total time spent sedentary (3.9 hours; p = .796) but the pattern of accumulation of the sedentary time differed. There were a greater number of bouts of > 20 minutes duration during school hours than after school hours (4.7 vs. 3

    Spatial abilities allow animals to retain and cognitively manipulate information about their spatial environment and are dependent upon neural structures that mature during adolescence. Exposure to stress in adolescence is thought to disrupt neural maturation, possibly compromising cognitive processes later in life. We examined whether exposure to chronic unpredictable stress in adolescence affects spatial ability in late adulthood. We evaluated spatial learning, reference and working memory,...

    Full Text Available 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 ( 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.

    Full Text Available Evidence supports the importance of parental involvement for youth’s ability to manage weight. This study utilized the stages of change (SOC model to assess readiness to change weight control behaviors as well as the predictive value of SOC in determining BMI outcomes in forty adolescent-parent dyads (mean adolescent age = 15 ± 1.84 (13–20, BMI = 37 ± 8.60; 70% white participating in a weight management intervention for adolescent females with polycystic ovary syndrome (PCOS. Adolescents and parents completed a questionnaire assessing their SOC for the following four weight control domains: increasing dietary portion control, increasing fruit and vegetable consumption, decreasing dietary fat, and increasing usual physical activity. Linear regression analyses indicated that adolescent change in total SOC from baseline to treatment completion was not predictive of adolescent change in BMI from baseline to treatment completion. However, parent change in total SOC from baseline to treatment completion was predictive of adolescent change in BMI, (t(24 = 2.15, p=0.043. Findings support future research which carefully assesses adolescent and parent SOC and potentially develops interventions targeting adolescent and parental readiness to adopt healthy lifestyle goals.

    Full Text Available The purpose of this study was to determine differences in bone mineral density (BMD among adolescent female tennis players (TPs and nontennis players (NTPs and to assess body composition as a predictor variable of BMD. Nineteen female TPs and 19 female NTPs, ages 14 to 18 years, participated in this study. Lumbar spine, total hip, femoral neck, forearms BMD, and body composition were assessed using dual-energy X-ray absorptiometry (DXA. Lumbar spine and total hip BMD measurements for TP were greater than NTP. However, these differences were not statistically significant (=0.37 and 0.12, resp.. TP had significantly greater femoral neck BMD than NTPs (=0.02. This difference might play an important role in preventing osteoporosis and decreasing the risk of fractures at the hip later in life.

    Full Text Available Background and Objectives: Acne vulgaris is a distressing skin condition, which can carry with it significant psychological disability. Oxidant/antioxidant imbalance leads to increased production of free radicals, that cause many diseases. Some nutrients, along with systemic oxidative stress, have been implicated in acne vulgaris. The goal of the present study was to assess oxidant and antioxidant status in correlation with the incidence of acne vulgaris in adolescent obese females. Materials and Methods: A total of 60 adolescent females (age 16-22 years were divided into four groups (15 each as follows: The first included obese females with acne; the second included obese females without acne; the third included non obese with acne and the fourth included non obese without acne. Fasting serum Malondialdehyde (MDA, β-carotene, and Vitamins A, E, and C were measured. In addition, platelet monoamineoxidase (MAO, and erythrocyte catechol-o-methyltransferase (COMT activities were determined. Results: It was found that serum MDA was statistically significantly decreased in obese and non obese subjects with acne, as compared to those without acne ( P < 0.05, P < 0.001 respectively. In contrast, the levels of β-carotene, vitamins A, E and C and the activity of MAO were significantly decreased in the obese and non obese with acne, as against the obese and non obese without acne. Interpretation: In obese subjects, increased fat content facilitates free radical production and lipid peroxidation, as indicated by increased MDA level, which is scavenged by the antioxidant vitamins. The decreased activity of MAO may be inhibited by free radicals and this causes psychological depression in adolescents. However there were non significant changes in the activity of COMT among the studied groups. Conclusion: The nutritional factors and a weakened antioxidant defense system may interplay, to increase the risk of psychological sequelae in acne vulgaris.

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

    This study contrasted female and male early adolescent sex role attitude and behavior development in an ecological context as defined by Bronfenbrenner. Data were the results of a state-wide survey of early adolescents and their parents. Hierarchical multiple regression was used to test both sex role attitude development and behavior development models. Only the models for attitude development were significant. The level of traditionalism of female sex role attitude development was significantly influenced by maternal employment, the level of traditionalism of the father's sex role attitudes in interaction with the amount of time he spent with his daughter, and chronological age. In contrast, the level of traditionalism of male sex role attitude development was significantly influenced by the level of traditionalism of the mother's sex role attitudes in interaction with the level of closeness to the mother that was reported by the son, and both mother's and father's perception of pubertal age. The implications of the findings for human development theory, early adolescence as a stage of development, and sex role theory and research are discussed.

    The intergenerational transmission of violence and the tendency for abused and neglected children to become abusers, delinquents, and violent offenders in their adult life is an important field to be understood. It is also important to understand these backgrounds to guide future preventative interventions. Through a cross-sectional study, the occurrence of abuse during childhood and adolescence of adult women incarcerated in a female state prison at Recife in northeast Brazil was investigated. Among 219 prisoners, 190 accepted to join the research; 149 were young women (23-27 years) with severe educational deficiency. Living in poor socioeconomical conditions with problematic and violent familiar relations, 116 (61 per cent) left home at the end of their adolescence and the same number reported having been abused (p abuses suffered and witnessed by the subjects and the perpetration of abuse against children and adolescents by themselves (p abuse suffered in childhood and adolescence of these women drove them to be abusers in adult life and could have been a predictive marker for their conduct disorders and subsequent criminal behavior.

    Full Text Available Background: Menstruation is an important milestone that results in development of sexual and reproductive capacity of girls. Adolescent girls do not have adequate knowledge about the abnormalities and healthy practices to be followed during menstruation. Objective:To find out the knowledge, attitude, practices regarding menstruation and treatment seeking behaviour for menstrual problems in adolescent females.Material & methods: The present cross sectional study was carried out in an urban field practice area of Department of Community Medicine, LLRM Medical College, Meerut on adolescent girls. A sample of 384 was derived and girls were selected by systematic random sampling technique. Detailed information was collected on a predesigned and pretested questionnaire. Results:38.5% girls were aware of menstruation prior to its onset out of which 66.9% learned from their mother. Only 14.6% of the menstruating girls were aware of at least one menstrual disorder. Dysmenorrhoea was found to be the most frequently occurring problem (58.4%, followed by oligomenorrhoea (16.2%, menorrhagia (13.9%, premenstrual tension (13.6%, infrequent menstruation (12.3% and polymenorrhoea (12.2%. Out of the 226(72.7% girls having menstrual problems 77.9% did not seek any treatment for their problems. 55.2% of the menstruating girls were using sanitary pads during menstruation. Conclusion: The adolescent girls are not well prepared and do not have adequate information regarding menstruation which is an important event of life.

    Adherence to self-management and medication regimens is required to achieve optimal blood glucose control in adolescents with type 1 diabetes mellitus. Non-adherence places adolescents at serious risk of short and long-term health complications. Adherence difficulties may be exacerbated by concurrent eating disorders. Diabulimia is a term used to describe the deliberate administration of insufficient insulin to maintain glycaemic control for the purpose of causing weight loss. This article explores the concept of diabulimia and the compounding complications of an eating disorder on maintaining self-management regimens in adolescents with diabetes. PMID:25204951

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

    Full Text Available 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.

    Full Text Available Women are major affected segment of society in any disaster in under developed countries. Floods of 2010, in Pakistan, affected more than 17 million people. Ultimately, it created several social, psychological and financial problems for affected females. The current paper aimed to study the socio-economic affects of floods on female teachers of private schools in tehsil headquarters Jampur. There were sixty two registered and non-registered private schools in the city in which five hundreds and seventy nine female teachers were working. Eight schools were selected as cluster to collect the data. Totally sample was comprised fifty eight female teachers. Semi structure interview and focus group discussion techniques were used to gather the data. Collected data were analyzed use thematic analysis approach. Findings indicated that female school teachers working in private school of city Jampur were badly affected in floods 2010. They had to face several social and financial problems. There was much space to improve relief and aid activities in the affected areas. Separate health facilities for women were also needed. The paper recommends better planning and its transparent and fair implementations in next rainy season.

The purpose of this study is to investigate whether exercise therapy and patient education are associated with larger improvements in neuromuscular...... knee control and maximal quadriceps torque compared with patient education alone. METHODS: This is an ancillary analysis of a cluster randomized controlled trial investigating the effect of patient education and exercise therapy on self-reported recovery in 121 adolescents with patellofemoral pain...... flexion/extension kinematics and maximal quadriceps torque. FINDINGS: There was an 8-15% greater decrease in the complexity of surface electromyography suggesting an improvement in neuromuscular knee control among those randomized to exercise therapy (0.08

  4. Neural systems supporting cognitive-affective interactions in adolescence: The role of puberty and implications for affective disorders

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Evidence from longitudinal studies suggests that adolescence may represent a period of vulnerability that, in the context of adverse events, could contribute to developmental trajectories toward behavioral and emotional health problems, including affective disorders. Adolescence is also a sensitive period for the development of neural systems supporting cognitive-affective processes, which have been implicated in the pathophysiology of affective disorders such as anxiety and mood disorders. In particular, the onset of puberty brings about a cascade of physical, hormonal, psychological, and social changes that contribute in complex ways to the development of these systems. This article provides a brief overview of neuroimaging research pertaining to the development of cognitive-affective processes in adolescence. It also includes a brief review of evidence from animal and human neuroimaging studies suggesting that sex steroids influence the connectivity between prefrontal cortical and subcortical limbic regions in ways that contribute to increased reactivity to emotionally salient stimuli. We integrate these findings in the context of a developmental affective neuroscience framework suggesting that the impact of rising levels of sex steroids during puberty on fronto-limbic connectivity may be even greater in the context of protracted development of prefrontal cortical regions in adolescence. We conclude by discussing the implications of these findings for future research aimed at identifying neurodevelopmental markers of risk for future onset of affective disorders.

    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 measures should be tested for their ability as tools to minimize the risk for the triad. PMID:26252427

    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 (Pgang 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.

    Emma L Anderson

    Full Text Available Epidemiological evidence for associations of Anti-Müllerian hormone (AMH with cardiometabolic risk factors is lacking. Existing evidence comes from small studies in select adult populations, and findings are conflicting. We aimed to assess whether AMH is associated with cardiometabolic risk factors in a general population of adolescent females.AMH, fasting insulin, glucose, HDLc, LDLc, triglycerides and C-reactive protein (CRP were measured at a mean age 15.5 years in 1,308 female participants in the Avon Longitudinal Study of Parents and Children (ALSPAC. Multivariable linear regression was used to examine associations of AMH with these cardiometabolic outcomes.AMH values ranged from 0.16-35.84 ng/ml and median AMH was 3.57 ng/ml (IQR: 2.41, 5.49. For females classified as post-pubertal (n = 848 at the time of assessment median (IQR AMH was 3.81 ng/ml (2.55, 5.82 compared with 3.25 ng/ml (2.23, 5.05 in those classed as early pubertal (n = 460, P≤0.001. After adjusting for birth weight, gestational age, pubertal stage, age, ethnicity, socioeconomic position, adiposity and use of hormonal contraceptives, there were no associations with any of the cardiometabolic outcomes. For example fasting insulin changed by 0% per doubling of AMH (95%CI: -3%,+2% p  = 0.70, with identical results if HOMA-IR was used. Results were similar after additional adjustment for smoking, physical activity and age at menarche, after exclusion of 3% of females with the highest AMH values, after excluding those that had not started menarche and after excluding those using hormonal contraceptives.Our results suggest that in healthy adolescent females, AMH is not associated with cardiometabolic risk factors.

  8. Adolescent knowledge and awareness about AIDS/HIV and factors affecting them in Bangladesh

    International Nuclear Information System (INIS)

    Adolescents are more vulnerable than adults of unplanned pregnancies, sexually transmitted diseases and HIV/AIDS. Among the adolescents, girls are more vulnerable to STDs including HIV/AIDS. Their knowledge about different diseases is very poor. This paper investigated adolescent's knowledge about sexually transmitted diseases including HIV/AIDS, its mode of transmission and ways of its prevention. Methods: Cross sectional study design was adopted for this study. A multistage cluster sampling technique was used to select the sample. Data on 3362 female adolescents irrespective of their marital status was analyzed. Results: The study found that a large proportion of adolescents were not aware about sexually transmitted diseases and AIDS. More than half (54.8%) of the adolescents ever heard about AIDS respectively. On an average, about one tenth of them had better knowledge on AIDS in terms of mode of transmission and prevention. The multivariate logistic regression analysis revealed that adolescent age, years of schooling and knowledge on STDs appeared to be important predictors of the awareness about AIDS (p<0.05). Conclusions: Useful and fruitful media campaigns to educate the adolescents regarding the health consequences of STDs including HIV/AIDS and integrated approach is strongly suggested for creating knowledge and awareness to control the spread of HIV and AIDS among young people in Bangladesh.

    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

    Data suggest that depressed affect and dietary restraint are related to disinhibited eating patterns in children and adults. Yet, experimental research has not determined to what extent depressed affect acutely affects eating in the absence of physiological hunger (EAH) in adolescents. In the current between-subjects experimental study, we measured EAH in 182 adolescent (13-17 y) girls (65%) and boys as ad libitum palatable snack food intake after youth ate to satiety from a buffet meal. Just prior to EAH, participants were randomly assigned to view either a sad or neutral film clip. Dietary restraint was measured with the Eating Disorder Examination. Adolescents who viewed the sad film clip reported small but significant increases in state depressed affect relative to adolescents who viewed the neutral film clip (p < .001). Yet, there was no main effect of film condition on EAH (p = .26). Instead, dietary restraint predicted greater EAH among girls, but not boys (p < .001). These findings provide evidence that adolescent girls' propensity to report restrained eating is associated with their greater disinhibited eating in the laboratory. Additional experimental research, perhaps utilizing a more potent laboratory stressor and manipulating both affective state and dietary restraint, is required to elucidate how state affect may interact with dietary restraint to influence EAH during adolescence.

    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 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. PMID:20205723

  16. Factors Affecting sex pheromone production in female cotton leaf worm moth, Spodoptera littoralis (boisd.)

    International Nuclear Information System (INIS)

    Factors influencing sex pheromone production in the cotton leaf worm female moth with emphasis on gamma radiation were investigated. To determine the effect of age on sex pheromone production, ether extracts of the female abdominal tips were prepared from virgin females of various ages in a concentration of 0.01 FE/mu L. Each female extract was tested against 1-2 days-old males. The obtained results indicated that virgin females could secrete sex pheromone early at the beginning of their life. The pheromone production increased rapidly to reach its maximum on the second day. To study the effect of daytime on sex pheromone production, the ether extracts of 1-2 days old virgin female abdominal tips were prepared at 3 hour-intervals, throughout the photo phase and scotophase in a concentration of 0.01 FE/mu L. The obtained results indicated that pheromone production showed a minimum concentration at mid-day during the photo phase. It then increased to a moderate concentration from 7:0 p.m. to 10:0 p.m. and reached its maximum titer at almost mid-night. The obtained data on the effect of gamma irradiation indicated that irradiation of 3 and 6-day-old female pupae with doses of 60 and 120 Gy, respectively caused a reduction of 28.1 and 27.3 % in male response, respectively, to female sex pheromone extracts. When full-grown female pupae were irradiated with 200 and 350 Gy, a reduction of 15.6 and 75% in male response, respectively, was reached. Thus, an irradiation dose of 350 Gy applied to full-grown female pupae could severely affect pheromone production of the emerging female moths

  19. Bone mineral density and nutritional indices in adolescent females with recently diagnosed anorexia

    International Nuclear Information System (INIS)

    Full text: Osteopenia/osteoporosis and fractures have been shown to occur with anorexia nervosa (AN). This study evaluated adolescent females diagnosed with AN less than 12 months previously to determine the presence of any significant bone mass reduction at this early stage of diagnosis and to evaluate the correlation between total body (TB) and lumbar spine (LS) bone mineral densities (BMD) and bone mineral content (BMC), and nutritional indices (body weight, body mass index (BMI), lean mass, fat mass and percentage fat). The subjects were 22 adolescent females aged 12-17 years (mean= 14.3 years) diagnosed with AN less than 12 months earlier (range 2.5-11 months; mean = 6.7 months). They had bone density measurements of the TB and LS using a Lunar DPX-L densitometer. Comparison was made with values of age-matched controls in the Lunar normative database. Although there was a tendency towards low TB and LS bone mass, these changes were not statistically significant. Bivariate analyses showed significant correlation between TB BMD and lean mass (P < 0.001) and weight (P < 0.001) and between TB BMC and lean mass (P < 0.001) and weight (P < 0.01). There was similar significant correlation between LS BMD and lean mass (P < 0.01) and weight (P<0.01), and between LS BMC and lean mass (P < 0.01) and weight (P < 0.01). With stepwise regression analysis, only lean mass remained significantly correlated with TB BMD and BMC and LS BMD and BMC. There was no longer any significant correlation with weight. In this study, the weight percentile was found to be correlated highly with the LS BMD Z-score (P < 0.01). Therefore, during adolescence, the lean mass in particular, but also body weight, are good indicators of bone densities. Adolescent females do not appear to show bone mass reduction in the early stages of diagnosis of anorexia nervosa. This suggests early intervention may preserve bone gain and attainment of normal peak bone mass

    Bennett, Camille

    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.

    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. PMID:25087723

    Full Text Available Background: nowadays, hypertension is a health problem directly causing disability and death. Epidemiological data suggest that pre- and postnatal nutrition can be an important factor in the etiopathogenesis of this disease. Objective: to evaluate the effects of low birth weight on blood pressure and kidney size in adolescent females. Methods: a cross-sectional study was conducted in 50 adolescent females from Marianao, Havana. The following variables were measured: weight, height, systolic and diastolic blood pressure, birth weight and length and body mass index. Kidney length, width, parenchyma and volume were measured by ultrasound. Results: differences in blood pressure related to weight and length at birth were nonsignificant. Renal variables did not show significant changes in the classification by birth weight. An important relationship between systolic blood pressure and two indicators of the relative kidney size was found. Conclusion: results did not show an association between low birth weight and high blood pressure. It is demonstrated that blood pressure values are positively related to body adiposity and small kidney size.

    The lower genital tracts of 20 sexually active adolescent females were examined for the presence of Mycoplasma hominis, Ureaplasma urealyticum, Corynebacterium genitalium, and Corynebacterium pseudogenitalium. Fifty percent of the asymptomatic adolescent females and 50% of the symptomatic adolescent females were colonized with M. hominis, which is higher than the percentage reported in adult females. None of the asymptomatic adolescent females and only 10% of the symptomatic adolescent females were colonized with U. urealyticum, which is much lower than the percentage reported in adults. None of the study patients was colonized with C. genitalium, but 25% were colonized with C. pseudogenitalium. No relationship was found between the presence of M. hominis in the lower genital tract and a clinically identifiable vaginal discharge or inflammatory changes in exfoliated cervical and vaginal epithelial cells. The presence of M.hominis in the lower genital tract does not appear to be influenced by use of oral contraceptives or antecedent pregnancy. PMID:7333925

    While depression is reportedly more prevalent in women than men, a neurobiological basis for this difference has not been documented. Chronic mild stress (CMS) is a widely recognized animal model, which uses mild and unpredictable environmental stressors to induce depression. Studies of chronic stress, mainly in males, have reported an increase in the relative intake of "comfort food" as a means of counteracting the effects of stress. This study was designed to test the hypothesis that genes for certain neurotrophic factors, stress markers, and appetite regulators would be expressed differentially in male and female rats exposed to chronic, mild stressors with access to a preferred diet. Gene expression for neuropeptide Y was upregulated in females purely in response to stressors, whereas that for the epidermal growth factor receptor (EGFR) and arginine vasopressin (AVP) in males and fatty acid synthase (FASN) in females responded primarily to diet. Genes for brain-derived neurotrophic factor (BDNF), AVP, and the cocaine-amphetamine regulator of transcription (CART) in males, and leptin in females, showed a significant response to the interaction between stressors and diet. Every affected gene showed a different pattern of expression in males and females. This study confirms the intimate relationship between dietary intake and response to stress at the molecular level, and emphasizes the sex- and gene-specific nature of those interactions. Therefore, it supports a neurobiological basis for differences in the affective state response to stress in males and females. PMID:17917078

    The neuropeptide oxytocin (OT), given acutely, reduces self-administration of the psychostimulant drug methamphetamine (METH). Additionally, chronic OT administration to adolescent rats reduces levels of alcohol consumption in adulthood, suggesting developmental neuroplasticity in the OT system relevant to addiction-related behaviors. Here, we examined whether OT exposure during adolescence might subsequently inhibit METH self-administration in adulthood. Female Sprague-Dawley rats were administered vehicle or OT (1 mg/kg, i.p.) once daily from postnatal days (PND) 28 to 37 (adolescence). At PND 62 (adulthood), rats were trained to self-administer METH (intravenous, i.v.) in daily 2-hour sessions for 10 days under a fixed ratio 1 (FR1) reinforcement schedule, followed by determination of dose-response functions (0.01-0.3 mg/kg/infusion, i.v.) under both FR1 and progressive ratio (PR) schedules of reinforcement. Responding was then extinguished, and relapse to METH-seeking behavior assessed following priming doses of non-contingent METH (0.1-1 mg/kg, i.p.). Finally, plasma was collected to determine pre-treatment effects on OT and corticosterone levels. Results showed that OT pre-treatment did not significantly inhibit the acquisition of METH self-administration or FR1 responding. However, rats pre-treated with OT responded significantly less for METH under a PR reinforcement schedule, and showed reduced METH-primed reinstatement with the 1 mg/kg prime. Plasma OT levels were also significantly higher in OT pre-treated rats. These results confirm earlier observations that adolescent OT exposure can subtly, yet significantly, inhibit addiction-relevant behaviors in adulthood.

    Anoplophora malasiaca (Coleoptera: Cerambycidae) is a serious pest that destroys various landscape and crop trees in Japan. We evaluated the precopulatory responses of three different A. malasiaca populations collected from mandarin orange, willow and blueberry trees. Most of the males accepted mates from within the same host plant population as well as females from the willow and blueberry populations. However, significant number of males from the blueberry and willow populations rejected females from the mandarin orange population immediately after touching them with their antennae. Because all three of the female populations produced contact sex pheromones on their elytra, the females of the mandarin orange population were predicted to possess extra chemicals that repelled the males of the other two populations. β-Elemene was identified as a key component that was only found in mandarin orange-fed females and induced a rejection response in willow-fed males. Our results represent the first example of a female-acquired repellent against conspecific males of different host plant populations, indicating that the host plant greatly affects the female's sexual attractiveness.

    Full Text Available Adolescence is a period of major physical, hormonal and psychological change. It is also characterized by a significant increase in the incidence of psychopathologies and this increase is gender-specific. Likewise, stress during adolescence is associated with the development of psychiatric disorders later in life. Previously, using a rat model of psychogenic stress (exposure to predator odor followed by placement on an elevated platform during the pre-pubertal period (postnatal days 28-30, we reported sex-specific effects on auditory and contextual fear conditioning. Here, we study the short-term impact of psychogenic stress before and during puberty (postnatal days 28-42 on behavior (novelty seeking, risk taking, anxiety and depression and hypothalamus-pituitary-adrenocortical (HPA axis activation during late adolescence (postnatal days 45-51. Peri-pubertal stress decreased anxiety-like behavior and increased risk taking and novelty seeking behaviors during late adolescence (measured with the elevated plus maze, open field and exposure to novel object tests and intake of chocopop pellets before or immediate after stress. Finally neither depressive-like behavior (measured at the forced swim test nor HPA response to stress (blood corticosterone and glucose were affected by peri-pubertal stress. Nevertheless, when controlling for the basal anxiety of the mothers, animals exposed to peri-pubertal stress showed a significant decrease in corticosterone levels immediate after an acute stressor. The results from this study suggest that exposure to mild stressors during the peri-pubertal period induces a broad spectrum of behavioral changes in late adolescence, which may exacerbate the independence-building behaviors naturally happening during this transitional period (increase in curiosity, sensation-seeking and risk taking behaviors.

    Full Text Available The purpose of this research was to determine the expected progression of adolescent female swimming performances using a longitudinal approach. The performances of 514 female swimmers (12–19 year olds who participated in one or more FINA-regulated annual international schools’ swimming championships over an eight-year period were analysed. Quadratic functions for each of the seven individual events (50, 100, 200 m freestyle, 100 m backstroke, breaststroke, butterfly, 200 m individual medley were determined using mixed linear models. The predicted threshold of peak performance ranged from 16.8 ± 0.2 (200 m individual medley to 20.6 ± 0.1 (100 m butterfly years of age, preceded by gradual rates of improvement (mean rate of 1.6% per year. However, following cross validation, only three events (100 m backstroke, 200 m individual medley and 200 m freestyle produced reliable models. Identifying the factors that contribute to the progression of female performance in this transitory period of life remains challenging, not least since the onset of puberty is likely to have occurred prior to reaching 12 years of age, the minimum competition age for this championship.

  16. Negative Mood Increases Selective Attention to Negatively Valenced Body Parts in Female Adolescents with Anorexia Nervosa.

    Jennifer Svaldi

    Full Text Available 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.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.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.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.

    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

    Full Text Available Abstract 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.

    Large brains are thought to result from selection for cognitive benefits, but how enhanced cognition leads to increased fitness remains poorly understood. One explanation is that increased cognitive ability results in improved monitoring and assessment of predator threats. Here, we use male and female guppies (Poecilia reticulata), artificially selected for large and small brain size, to provide an experimental evaluation of this hypothesis. We examined their behavioural response as singletons, pairs or shoals of four towards a model predator. Large-brained females, but not males, spent less time performing predator inspections, an inherently risky behaviour. Video analysis revealed that large-brained females were further away from the model predator when in pairs but that they habituated quickly towards the model when in shoals of four. Males stayed further away from the predator model than females but again we found no brain size effect in males. We conclude that differences in brain size affect the female predator response. Large-brained females might be able to assess risk better or need less sensory information to reach an accurate conclusion. Our results provide experimental support for the general idea that predation pressure is likely to be important for the evolution of brain size in prey species.

    The objective of this study was to study the proportion of Ecuadorian students fulfilling criteria on the Eating Attitudes Test (EAT) in relation to socioeconomic status. Seven hundred and twenty three female adolescent participants recruited from Quito, Ecuador were administered a brief questionnaire consisting of the EAT-40 as well as lifestyle questions. Mean EAT-40 score was 17.12, with 14% fulfilling criteria. Lower socioeconomic status and watching more television predicted higher scores; however BMI, age, and positive smoking status failed to correlate. The presently unvalidated Spanish version of the EAT-26 highly correlated with the validated EAT-40 (R=0.94). A higher than expected proportion of Ecuadorians are at risk for eating disorders, especially among lower socioeconomic groups. The EAT-26 should be considered for validation as a primary screening tool in Latin America. PMID:18307113

    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.

    Full Text Available Early life events influence life-long patterns of emotionality and stress responsiveness and alter the rate of brain and body aging.  Much research attention has focused on the programming effects of the hypothalamus pituitary axis (HPA in early life and on understanding HPA function in response to stressors in adulthood. In comparison, there has been relatively little research on adolescence, a time of significant brain development particularly in the frontal lobe and a time which is of great importance for mental and physical health. The hippocampus, amygdala, and prefrontal cortex undergo stress-induced structural remodeling, which alters behavioral and physiological responses. During adolescence, HPA function is characterized by a prolonged activation in response to stressors compared to adulthood, which may render ongoing development of the brain vulnerable. Stress reactivity is markedly influenced by both the pubertal maturation and the experience of the individual. The frequency of the pulses is increased in chronic stress, since the neuroendocrine system is such a good candidate for mediators of many diseases linked to chronic stress. The activity of HPA axis  in life time of female,  sex maturity, pregnancy or lactation is a plasticity of the diurnal rhythm of pulse amplitude; chronic stress can change this program for   formation disorder in behavioral and physiological responses.

    2010-05-01

    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. PMID:19595563

    Depressive symptomatology is associated with impaired recognition of emotion. Previous investigations have predominantly focused on emotion recognition of static facial expressions neglecting the influence of social interaction and critical contextual factors. In the current study, we investigated how youth and maternal symptoms of depression may be associated with emotion recognition biases during familial interactions across distinct contextual settings. Further, we explored if an individual's current emotional state may account for youth and maternal emotion recognition biases. Mother-adolescent dyads (N = 128) completed measures of depressive symptomatology and participated in three family interactions, each designed to elicit distinct emotions. Mothers and youth completed state affect ratings pertaining to self and other at the conclusion of each interaction task. Using multiple regression, depressive symptoms in both mothers and adolescents were associated with biased recognition of both positive affect (i.e., happy, excited) and negative affect (i.e., sadness, anger, frustration); however, this bias emerged primarily in contexts with a less strong emotional signal. Using actor-partner interdependence models, results suggested that youth's own state affect accounted for depression-related biases in their recognition of maternal affect. State affect did not function similarly in explaining depression-related biases for maternal recognition of adolescent emotion. Together these findings suggest a similar negative bias in emotion recognition associated with depressive symptoms in both adolescents and mothers in real-life situations, albeit potentially driven by different mechanisms.

  13. Hormonal status and age differentially affect tolerance to the disruptive effects of delta-9-tetrahydrocannabinol (Δ9-THC on learning in female rats

    Full Text Available The effects of hormone status and age on the development of tolerance to D9-THC were assessed in sham-operated (intact or ovariectomized (OVX female rats that received either intraperitoneal saline or 5.6 mg/kg of D9-THC daily from postnatal day (PD 75 to 180 (early adulthood onward or PD 35 to 140 (adolescence onward. During this time, the 4 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 D9-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 D9-THC, all of the D9-THC groups developed tolerance. However, the magnitude of tolerance, as well as the effect of hormone status, varied with the age at which chronic D9-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 D9-THC; striatal protein expression was not consistently affected by either manipulation. Hippocampal BDNF 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 (D9-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.

    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

    2008-06-26

    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.

    Full Text Available Objective: In Nigeria the rate of contraceptive use among sexually active adolescents is about 30%, considerably lower than the rates reported for developed countries. This study aimed to determine the knowledge, perception and practice of emergency contraception among female adolescent hawkers in Rigasa community, a suburb of Kaduna town.Materials and Methods: A cross sectional descriptive study of 1200 adolescent female hawkers aged 15–29 years was carried out in 2008, using both self and interviewer administered questionnaires. Results: Vast majority of the respondents are divorcees, constituting 92%. About 46% of them have never attended formal school before marriage. Of the 18 participants who were aware of emergency contraception; none correctly identified 72 hours as the time limit for the method’s use. Antibiotics or home remedies such as dye Robin Blue mixed with Coca cola or mixed with lime or lime mixed with potash and salt water were mentioned as unlisted methods of emergency contraception by responders. Conclusion: It is glaring that there exist a yawning gap of information and knowledge on contraception in general and emergency contraception in particular among female adolescent hawkers. The need to inform this target group about reproductive health generally and unwanted pregnancy in particular would not be out of place.

    2009-01-01

    Full Text Available Background: Investigations have suggested that poor compliance could be an indicator of poor relationship with family and could be related to the person′s personality traits. Aim: The aim of this study was to determine the effect of parents attitude, the anxiety during treatment and self-confidence/self-care of the patient on cooperation during orthodontic treatment. Materials and Methods: The study material consisted of questionnaires completed by 82 adolescent patients and their parents. The patients were divided into two groups of 42 compliant and 40 non-compliant patients. The above-mentioned questionnaries were State-Trait Anxiety Inventory-STAI, Piers-Harris Children′s Self Concept Scale and The Exercise of Self-Care Agency for the patients and Mc Master Family Assessment Device and Parental Attitude Research Instrument-PARI for the parents. Results: The problem solving and caring attitude of the father and his determinative role in the family had a positive infulence on the compliance of the child. The patients who showed better compliance also had a lower state of anxiety, which could also be explained by the positive effect of the attitude of the father in the family. Conclusion: It would be useful to overcome the increased state of anxiety of the child in the orthodontic clinic by using educational and relaxation techniques. Besides, it would be wise to ask the father to be present at the first appointment during part of the education of the child.

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

    Previous research has illustrated associations among daily experiences, emotions and stress-responding physiological systems. Recently, investigators have examined salivary alpha-amylase (sAA), a surrogate marker of the autonomic nervous system, and its associations with affect. The current study examined associations among affective valence, arousal and sAA across three different time courses at the momentary, daily and inter-individual level to understand varying influences of adolescents' daily emotional experiences on sAA reactivity and diurnal sAA activity. Adolescents (N=82) provided salivary samples and diary reports of affect and experiences five times a day for three consecutive days. They also completed self-report questionnaires on trait affect. Findings from multilevel growth curves demonstrated that adolescents in our sample displayed typical sAA diurnal rhythms with levels dropping 30 min after waking and then increasing across the day to a peak in the late afternoon. Within person momentary experiences of high arousal positive affect were associated with momentary sAA reactivity. Prior day experiences of high arousal negative affect were associated with a greater amylase awakening response (i.e., greater decrease) and flatter slopes the next day. Trait positive affect was also associated with flatter sAA slopes. Our findings suggest that both affective arousal and valence should be accounted for when examining differences in sAA reactivity and diurnal patterns. Further, our results indicated that emotion-physiology transactions among adolescents occur over varying time scales for salivary alpha-amylase as well as cortisol. PMID:25076484

    Objective To identify predictors of developing a stress fracture among adolescent females during a seven-year period. Design Prospective cohort study Setting Adolescent females living throughout the United States Participants 6831 females, aged 9–15 years at baseline, in the Growing Up Today Study (GUTS), an ongoing prospective cohort study. Main Exposures Exposures were assessed by self-report questionnaires completed by adolescent girls in 1996, 1997, 1998, 1999, 2000, 2001, and 2003. The adolescent girl’s history of stress fracture, including age when fracture occurred and site, were reported by their mothers, who are registered nurses, in 2004. Cox proportional hazards models were used in the analysis. Main Outcome Measure Incident stress fracture that occurred between 1997 and 2004. Results During seven years of follow-up, 267 females (3.9%) developed a stress fracture. Independent of age, age at menarche, family history of fracture, and hours per week of low and moderate impact activity, hours per week of running (relative risk (RR)=1.13, 95% confidence interval (CI) 1.04–1.23), basketball (RR=1.12, 95% CI 1.03–1.22) and cheerleading and gymnastics (RR=1.12, 95% CI 1.02–1.23) were significant predictors of developing a stress fracture. No other type of high impact activity was associated with an increased risk. Conclusions Females who engage in running, basketball, cheerleading, or gymnastics should be encouraged to include varied training in lower impact activities to decrease the cumulative amount of impact in order minimize their risk of stress fractures.

    X-linked sideroblastic anemia (XLSA) is a rare hereditary disorder that typically manifests in males as microcytic anemia. Here, we report a family with XLSA that affects females and manifests as macrocytic anemia. The proband was a Japanese woman harboring a heterozygous mutation c.679C>T in the ALAS2 gene. This mutation causes the amino acid substitution R227C, which disrupts the enzymatic activity of erythroid-specific δ-aminolevulinic acid synthase. The mutation was not detected in the ALAS2 complementary DNA from peripheral blood red blood cells of the proband, indicating that the cells were mostly derived from erythroblasts expressing wild-type ALAS2. The proband's mother, who had been diagnosed with myelodysplastic syndrome, also had XLSA with the same mutation. Clinicians should be aware that XLSA can occur not only in males but also in females, in whom it manifests as macrocytic anemia. PMID:26862056

    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. PMID:25905734

    Cannabis continues to be the most accessible and popular illicit recreational drug. Whereas current data link adolescence cannabinoid exposure to increased risk for dependence on other drugs, depression, anxiety disorders and psychosis, the mechanism(s) underlying these adverse effects remains controversial. Here we show in a mouse model of female adolescent cannabinoid exposure deficient endocannabinoid (eCB)-mediated signaling and presynaptic forms of long-term depression at adult central glutamatergic synapses in the prefrontal cortex. Increasing endocannabinoid levels by blockade of monoacylglycerol lipase, the primary enzyme responsible for degrading the endocannabinoid 2-arachidonoylglycerol (2-AG), with the specific inhibitor JZL 184 ameliorates eCB-LTD deficits. The observed deficit in cortical presynaptic signaling may represent a neural maladaptation underlying network instability and abnormal cognitive functioning. Our study suggests that adolescent cannabinoid exposure may permanently impair brain functions, including the brain's intrinsic ability to appropriately adapt to external influences. PMID:25979486

    Early maternal deprivation (MD), 24h of dam-litter separation on postnatal day (PND) 9, has been proposed as a suitable animal model to investigate some neuropsychiatric disorders with a base in neurodevelopment that also compromises metabolic and endocrine homeostasis. Atypical antipsychotics are frequently prescribed to children and adolescents as first-line treatment for several mental disorders despite the adverse metabolic effects frequently reported. However, persistent long-term effects after adolescent drug therapy have been scarcely investigated. In the present study we aimed to investigate the long-lasting metabolic and behavioral effects of MD in combination with the administration of an atypical antipsychotic, i.e. olanzapine, during adolescence. For that purpose, male and female Wistar rats not exposed (control group, Co) and exposed to the MD protocol were administered with oral olanzapine (Olan, 7.5mg/kg/day) or vehicle (Vh, 1mM acetic acid) in drinking water from PND 28 to PND 49. Body weight gain, glycaemia and plasma triglyceride (TG) levels were evaluated as relevant metabolic parameters. MD significantly diminished body weight gain, while Olan administration only induced a subtle decrease in body weight gain among female animals in the long-term. Olan discontinuation decreased plasma TG levels in adult rats, an effect that was counteracted by neonatal exposure to the MD protocol. Both MD and Olan treatment impaired cognitive function in the novel object recognition test, although no interaction between treatments was observed. Neither MD nor Olan administration affected psychotic-related symptoms evaluated in the prepulse inhibition task, although animals treated with Olan showed an increased reactivity to the first acoustic stimulus. MD diminished the corticosterone stress-induced response among females, and reduced the expression of CB1 receptors in the hippocampus of both male and female rats. Notably, Olan administration tended to

    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.

    This study aimed to investigate the effects of Phlomis umbrosa root on bone growth and growth mediators in rats. Female adolescent rats were administered P. umbrosa extract, recombinant human growth hormone or vehicle for 10 days. Tetracycline was injected intraperitoneally to produce a glowing fluorescence band on the newly formed bone on day 8, and 5-bromo-2'-deoxyuridine was injected to label proliferating chondrocytes on days 8-10. To assess possible endocrine or autocrine/paracrine mechanisms, we evaluated insulin-like growth factor-1 (IGF-1), insulin-like growth factor binding protein-3 (IGFBP-3) or bone morphogenetic protein-2 (BMP-2) in response to P. umbrosa administration in either growth plate or serum. Oral administration of P. umbrosa significantly increased longitudinal bone growth rate, height of hypertrophic zone and chondrocyte proliferation of the proximal tibial growth plate. P. umbrosa also increased serum IGFBP-3 levels and upregulated the expressions of IGF-1 and BMP-2 in growth plate. In conclusion, P. umbrosa increases longitudinal bone growth rate by stimulating proliferation and hypertrophy of chondrocyte with the increment of circulating IGFBP-3. Regarding the immunohistochemical study, the effect of P. umbrosa may also be attributable to upregulation of local IGF-1 and BMP-2 expressions in the growth plate, which can be considered as a GH dependent autocrine/paracrine pathway.

    This paper investigates the effect of body size on dating and sexual experiences of white (non-Hispanic) and African American (non-Hispanic) female adolescents. Using data from Add-Health, we estimate the effects of obesity and BMI z-score on the probability of having been involved in a romantic relationship, having ever been touched in the genital area in a sexual way, and having ever engaged in sexual intercourse. We find that obese white teenage girls are less likely to have been in a romantic relationship compared to their non-obese counterparts. In addition, obese white girls are less likely to ever have had sex (intercourse) or to ever have been intimate. There are no systematic differences in relationship experiences and sexual behaviors between obese and non-obese black girls. Overall, the estimated relationships are very robust to common environmental influences at the school-level and to the inclusion of proxies for low self-esteem, attitudes toward sex and interviewer assessment of appearance and personality. Instrumental variables estimates and estimates from models with lagged weight status confirm the overall patterns. PMID:24361085

    Juvenile hormone (JH) and dopamine are involved in the stress response in insects. The insulin/insulin-like growth factor signalling pathway has also recently been found to be involved in the regulation of various processes, including stress tolerance. However, the relationships between the JH, dopamine and insulin signalling pathways remain unclear. Here, we study the role of insulin signalling in the regulation of JH and dopamine metabolism under normal and heat stress conditions in Drosophila melanogaster females. We show that suppression of the insulin-like receptor (InR) in the corpus allatum, a specialised endocrine gland that synthesises JH, causes an increase in dopamine level and JH-hydrolysing activity and alters the activities of enzymes that produce as well as those that degrade dopamine [alkaline phosphatase (ALP), tyrosine hydroxylase (TH) and dopamine-dependent arylalkylamine N-acetyltransferase (DAT)]. We also found that InR suppression in the corpus allatum modulates dopamine, ALP, TH and JH-hydrolysing activity in response to heat stress and that it decreases the fecundity of the flies. JH application restores dopamine metabolism and fecundity in females with decreased InR expression in the corpus allatum. Our data provide evidence that the insulin/insulin-like growth factor signalling pathway regulates dopamine metabolism in females of D. melanogaster via the system of JH metabolism and that it affects the development of the neuroendocrine stress reaction and interacts with JH in the control of reproduction in this species.

    Adolescence is a unique period of development, marked by maturation of the prefrontal cortex (PFC), a region important for executive functioning. During this time, the human PFC decreases in overall volume and thickness. Likewise in adolescent rodents, losses of neurons, dendrites, dendritic spines and neurotransmitter receptors have been documented within the medial prefrontal cortex (mPFC), sometimes with sex and layer specificity. However, changes in the number of synapses during this time have not been examined. In the present study, we stereologically quantified the number of synaptophysin-immunoreactive boutons in the male and female rat mPFC across multiple time points from the juvenile period through adulthood (postnatal days (P) 25, 35, 45, 60 and 90). In females, there was a significant decrease in synaptophysin boutons between P35 and P45, coinciding with the onset of puberty. In males, there was no significant main effect of age on synaptophysin boutons; however, in both males and females, pubertal onset was associated with significant synaptic losses. These results suggest that puberty is a critical period for synaptic pruning within the rat mPFC, potentially contributing to maturation of adolescent executive function.

    Full Text Available The objective of this study was to determine what factors female consumers valued more when they buy nail polish. Ninety-eight female consumers participated in a nail polish consumer study at the Sensory Analysis Center, Kansas State University. A questionnaire containing a check-all-that-apply (CATA question, behavior questions and demographic questions was presented to each consumer. In the CATA question, the factors that may affect consumers’ decision to buy a nail polish were asked, including both sensory and non-sensory factors. The frequency in percent for the factors was calculated. Sensory appeal, price and convenience of usage were the top factors that affected consumers’ buying decisions. Consumers valued sensory appeal and convenience of usage; this suggested that a nail polish company’s product development and advertising departments may want to focus on these two areas, primarily. The information presented in this study could help a nail polish company understand more about consumer segmentation and advertising strategy.

    Background Sexually transmitted infections (STIs) are common among adolescents, and multiple STIs over one’s lifetime can increase health risks. Few studies have assessed lifetime STI prevalence. This study evaluates minority, underserved adolescents’ self-reported lifetime STI history and objective STI rates. Methods Lifetime STI rates of female patients at an urban adolescent health center were obtained from self-administered questionnaires. Additionally, STI test results were retrieved from electronic medical records. Results Patients reported a high lifetime prevalence of STIs. By comparing self-report and objective data, underreporting was identified for chlamydia, gonorrhea, and herpes. Conclusions STI rates in at-risk adolescent females are higher than in the general population and remain elevated over time. Lifetime STI reports could expand our understanding of sexual health and should be further studied. Underreporting, which may increase health risks and hinder health care delivery, requires further investigation. Improvements in STI screening and prevention targeting at-risk populations are warranted. PMID:24807980

    Many researchers underscore the importance of coping in the daily lives of adolescents, yet very few studies measure this and related constructs at this level. Using a daily diary approach to stress and coping, the current study evaluated a series of mediational coping models in a sample of low-income minority adolescents (N = 89). Specifically, coping was hypothesized to mediate the relationship between attributional style (and dimensions) and daily affect. Using random coefficient regression modeling, the relationship between (a) the locus of causality dimension and positive affect was completely mediated by the use of acceptance and humor as coping strategies; (b) the stability dimension and positive affect was completely mediated by the use of both problem-solving and positive thinking; and (c) the stability dimension and negative affect was partially mediated by the use of religious coping. In addition, the locus of causality and stability (but not globality) dimensions were also directly related to affect. However, the relationship between pessimistic explanatory style and affect was not mediated by coping. Consistent with previous research, these findings suggest that attributions are both directly and indirectly related to indices of affect or adjustment. Thus, attributions may not only influence the type of coping strategy employed, but may also serve as coping strategies themselves. PMID:22029618

    Full Text Available Background: Globally, domestic violence against females is common across culture, religion, class and ethnicity. There are various reasons for domestic violence and it might have serious health outcomes. Objectives: The study was undertaken to determine the prevalence, characteristics, reasons and the socio-demographic correlates of domestic violence, if any, and to find out the perceptions of the females to cope with the act of violence and to overcome the situation. Materials and Methods: A cross-sectional observational study was undertaken by interviewing 141 adult and adolescent females residing in a village of West Bengal, with the help of a pre-designed and pre-tested questionnaire. Data were analyzed statistically by simple proportions and tests of significance (Chi-square test. Results: Out of 141 respondents, 33 (23.4% adult and adolescent females in this village were exposed to domestic violence in the past year. Among the demographic characteristics, statistically significant maximum prevalence was observed among 30-39 years age group, illiterate and unmarried females. For most of the females who were exposed to domestic violence, their husbands acted as the perpetrators (72.73% and they reported slapping as the specific act of physical assault (72.73%. Majority of the respondents reported that opportunity of education (31.9%, being economically productive (31.9% and better family income (23.4% would help them to overcome the situation. Conclusion: This study emphasizes the need for justified female empowerment and this calls for multidisciplinary approach to develop public health measures, which would most effectively address the problem of domestic violence.

    Full Text Available Sex trafficking has been a long-standing concern in Nepal. Very little has been achieved, however, in terms of actual reduction in the number of victims despite numerous anti-sex trafficking programs. This situation may be attributable to a lack of empirical evidence upon which to formulate anti-sexual trafficking interventions. This study aimed to assess sex trafficking-related knowledge, awareness and attitudes, and factors associated with sex trafficking awareness and attitudes towards the victims of sex trafficking and/or anti-sex trafficking campaigns among adolescent female students in Nepal.A cross-sectional study was conducted between August-September 2013 among 292 adolescent female students (>10 years old using systematic random sampling from three high schools in Sindhupalchowk district, Nepal. As an initial step, descriptive analyses were employed to characterize the data and multivariate logistic regression analyses were used to explore factors associated with sex trafficking awareness and related attitudes.Seventy-six percent of sampled students reported that they were aware of sex trafficking and 94.6% indicated media (i.e., radio or television as the primary sources of their knowledge.

    Animals signal their reproductive status in a range of sensory modalities. Highly social animals, such as primates, have access not only to such signals, but also to prior experience of other group members. Whether this experience affects how animals interpret reproductive signals is unknown. Here, we explore whether familiarity with a specific female affects a male's ability to assess that female's reproductive signals. We used a preferential looking procedure to assess signal discrimination...

    Although adolescent cigarette smoking remains a critical public health concern, little is known about the reinforcing mechanisms governing smoking in this vulnerable population. To assess predictions derived from both positive and negative reinforcement models of drug use, the authors measured the acute effects of nicotine, as administered via tobacco cigarettes, on both positive and negative affect in a group of 15- to 18-year-old smokers. A matched group of nonsmokers served as a comparison group. Findings revealed that whereas adolescents who smoked a cigarette experienced reductions in both positive and negative affect, the observed reductions in negative affect were moderated by nicotine content of the cigarette (high yield vs. denicotinized), level of nicotine dependence, level of baseline craving, and smoking expectancies pertinent to negative affect regulation. Nonsmokers experienced no change in affect over the 10-min assessment period, and no interaction effects were observed for positive affect. Overall, the findings conform to a negative reinforcement model of nicotine effects and strongly suggest that, even among young light smokers, nicotine dependence and resultant withdrawal symptomatology may serve as motivating factors governing smoking behavior.

    Introduction Success of orthodontic retention with removable retainers almost entirely depends on patients’ compliance. Aim This study was carried out to investigate the relationship between adolescent orthodontic patients’ compliance and various clinical and social factors. Materials and Methods The data were collected from 77 orthodontic patients aged 7-11 years old who had finished the full fixed appliance therapy. Hawley’s retainers were used in 34 patients and 43 patients used Vacuum Formed Retainers (VFRs). The subjects completed a questionnaire including several identifiers allowing the respondents to be classified into subgroups. They were also asked to indicate how long they wore their retainers during the day, by writing the number of hours in the report-card for the next three months. Comparison of the results was performed by one-way ANOVA and independent sample-t tests. Results No significant differences were found between males and females. Type of the retainer, patients’ grade of study, mothers’ occupation, clinicians’ and parents’ attitudes and filling the report cards had significant effect on mean wear hours per day. When compliance of the patients was assessed according to treatment location, Living place, parents’ educational degrees and ethnicity, no significant differences could be found. Conclusion The adolescent patients’ compliance was greater with VFRs than with Hawley’s retainers. Parental attitude and doctor-patient relationship had a great impact on adolescent patients’ compliance.

    When the human papillomavirus (HPV) vaccine was approved in 2006, an extensive direct-to-consumer (DTC) advertising campaign raised awareness and promoted vaccination. This study explores adolescents' exposure to and understanding of the messages in these advertisements. Sixty-seven African American females participated in a focus group about DTC advertising for the HPV vaccine. Virtually all adolescents had seen an HPV vaccine DTC advertisement, but most did not understand the health information contained in it. If DTC advertising is to be an effective source of health information for adolescents in the future, it must take into account the unique features of an adolescent audience. PMID:22054031

    Physical activity modulates bone growth during adolescence, but an effective activity has not been identified for general use. PURPOSE To examine the effect of a school-based resistance-training program on skeletal growth in peri-menarcheal females. METHODS 6th grade girls participated in a 7-month, resistance-training program (INT) embedded in physical education classes (PE). Age and maturity matched controls (CON) from a neighboring school participated in standard PE. INT dose defined high (HI) and low (LO) groups. At baseline (BL) and follow-up (FU), Non-INT organized activity (PA, h/wk) and maturity status were recorded; DXA scans assessed total-body, distal radius, proximal femur, and lumbar spine. Regression models analyzed growth in bone outcomes for HI v CON, accounting for age, Tanner stage, height, and PA. RESULTS 44 girls (22 HI, 22 CON) were 11.7 ± 0.3 yrs at BL; all were ≤6 mo post-menarche and did not differ in bone growth over the course of the intervention (p>0.05). However, in a sub-analysis limited to subjects who were Tanner breast II (T2) or III (T3) at BL (n=21 CON, n=17 HI), T2 HI had greater gains in narrow neck (NN) width (p=0.01) compared to T2 CON, while T3 HI had greater gains in L3 BMD (p=0.03) compared to T3 CON. CONCLUSIONS In a group of T2 and T3 6th grade girls, a school-based resistance-training intervention produced maturity-specific differential gains for HI v CON at the hip and spine. PMID:24114402

    Chewing behavior may show sex differences; thus, the present study aimed to compare the masticatory aspects and the prediction of masticatory performance between male and female adolescents. Ninety-one healthy subjects (47 girls, 44 boys), caries-free and aged 14-17years, were included. Masticatory performance and maximal bite force were evaluated using a color-changeable chewing gum and digital gnathodynamometer, respectively. Masticatory behavior was assessed by the subjective aspect of the quality of the masticatory function (validated questionnaire) and the Orofacial Myofunctional Evaluation with Scores expanded (OMES-e) was used to determine chewing time, frequency of chewing cycles and other aspects. Salivary flow rate was also assessed. The physical examination involved measurements of facial morphometry, body weight, height, skeletal muscle mass, and dental/occlusal evaluations. It was observed that boys showed larger facial dimensions, higher bite force and chewing frequency and better masticatory performance than girls. They also showed shorter chewing time, fewer chewing cycles and lower score for OMES-e (that is, more changes in orofacial myofunctional aspects). Bite force showed a weak correlation with skeletal muscle mass only in boys (r=0.3035; p=0.0451). The masticatory performance was dependent on the bite force in boys (Adj R(2)=19.2%; Power=84.1%); among girls, masticatory performance was dependent on the frequency of chewing cycles and masticatory behavior (subjective aspect) (Adj R(2)=34.1%; Power=96.1%). The findings support the existence of sex differences in many masticatory aspects of function and behavior, hence the importance of considering sex differences when evaluating masticatory function and myofunctional therapy outcomes among young subjects.

    Full Text Available Selective serotonin reuptake inhibitor medications are one of the most common treatments for mood disorders. In humans, these medications are taken orally, usually once per day. Unfortunately, administration of antidepressant medications in rodent models is often through injection, oral gavage, or minipump implant, all relatively stressful procedures. The aim of the present study was to investigate how administration of the commonly used SSRI, fluoxetine, via a wafer cookie, compares to fluoxetine administration using an osmotic minipump, with regards to serum drug levels and hippocampal plasticity. For this experiment, adult female Sprague-Dawley rats were divided over the two administration methods: (1 cookie and (2 osmotic minipump and three fluoxetine treatment doses: 0, 5, or 10 mg/kg/day. Results show that a fluoxetine dose of 5 mg/kg/day, but not 10 mg/kg/day, results in comparable serum levels of fluoxetine and its active metabolite norfluoxetine between the two administration methods. Furthermore, minipump administration of fluoxetine resulted in higher levels of cell proliferation in the granule cell layer (GCL at a 5 mg dose compared to a 10 mg dose. Synaptophysin expression in the GCL, but not CA3, was significantly lower after fluoxetine treatment, regardless of administration method. These data suggest that the administration method and dose of fluoxetine can differentially affect hippocampal plasticity in the adult female rat.

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

    Depression may be a risk factor for overweight status, but mechanisms involved in this relationship are unclear. This study explored behavioral factors involved in the relationship between adolescent depression symptoms and adult overweight status. A population-based cohort of female participants in Project EAT (n=1035) was followed over 10 years and reported on psychological functioning, weight status and eating and activity patterns in early/middle adolescence (1999=Time 1; T1), middle adolescence/early young adulthood (2004=Time 2; T2) and early/middle young adulthood (2009=Time 3; T3). Structural equation models were fit which included T1 depression scores predicting overweight status at T3, with T2 fruit and vegetable consumption, moderate-to-vigorous physical activity and binge eating examined as mediators. There were small but significant effects of T1 depression scores predicting an increased likelihood of T3 overweight status (standardized estimate=0.038; P=0.007), and of T2 binge eating mediating the relation between T1 depression and T3 overweight status (standardized indirect effect estimate=0.036; P=0.009). Binge eating may be one pathway to overweight among depressed females, suggesting that recognition and treatment of eating pathology in individuals with depression may help prevent overweight. Examination of other behavioral (and non-behavioral) factors explaining the relationship between depression and overweight is warranted.

    RTI International is acknowledged for supporting the time of Susan McRitchie, Keeley Pratt and Susan Sumner to participate in the design, execution, or analysis of this study. East Carolina University would like to acknowledge Brittney France for being a triangulated investigator for the qualitative analysis and to the Pitt Memorial Hospital Foundation for financial support of the healthy lifestyles camp. Our purpose was to evaluate the views of obese African-American (AA) female adolescents concerning parent and family factors relating to obesity and a healthy lifestyle. Obese AA female adolescents enrolled in a residential healthy lifestyle program completed inventories measuring family functioning and perceptions of parenting styles, and participated in focus groups to identify themes regarding parent and family involvement in healthy lifestyle change. The majority of participants' mothers were scored as "inductive/authoritative" and fathers were "indulgent". Mothers reportedly were seen as more likely to encourage dieting to control weight than fathers. Common themes of the focus groups included a desire for family involvement, identification of family behaviors that were supportive as well as those which were perceived as unhelpful. Though generalizability of these results is limited by a homogenous small sample size, our results suggest that obese adolescents seeking weight loss treatment desire significant family involvement in their efforts.

    In crustaceans, mating occurs during the ecdysis after female molting. During this period, a male transfers its spermatophore into a female which, in some species, stores the spermatophore for a long period prior to spawning and fertilization. However, in some species including the giant freshwater prawn, Macrobrachium rosenbergii, the male deposits its spermataphore onto the external surface of the thoracic segment of the female which affects the spawning time and maternal behavior. This study investigated the spawning behavior of the M. rosenbergii females, which was divided into pre-spawning, spawning, and post-spawning phases. It was revealed that mated female prawns with attached spermatophore exhibited an earlier spawning than unmated individuals, leading to assessment of the factors that may elicit this phenomenon. Four groups of female prawns were allocated to groups including mating females with spermatophore still attached, mating females with the spermatophore removed, artificially inseminated females with spermatophores, and an unmated control. There was a significant reduction in the time of egg-spawning in the presence of spermatophores, and the mating activity was also a contributing factor. Furthermore, over 90% of the mated and artificially inseminated females in which spermatophores were deposited carried the eggs in the abdominal brood chamber until completion of embryonic development while others discarded the eggs within 2 days post-spawning. This study implies that the spermatophore may contain ovulation-inducing factors which stimulate an earlier spawning and fostering of brooding behavior.

    Fragile X syndrome (FXS) is associated with executive function (EF) and independent living skills (ILS) deficits. We examined the role of childhood EF in ILS during adolescence/early adulthood in females with FXS and two comparison groups in the same age range (matched for IQ [IQ/Age group] and with another genetic condition, Turner syndrome [TS group]). EF and ILS were significantly higher for the FXS group than the IQ/Age group but did not differ from the TS group. For the FXS group, age and EF were significant predictors of ILS during adolescence/early adulthood, but there were no statistically significant longitudinal associations between EF and ILS. Our findings suggest that impairments in EF may have a significant effect on ILS in FXS. PMID:27611354

  11. Is competition making a comeback? Discovering methods to keep female adolescents engaged in STEM: A phenomenological approach

    Science.gov (United States)

    Notter, Kathryn Betz

    The decreasing number of women who are graduating in the Science, Technology, Engineering and Mathematics (STEM) fields continues to be a major concern. Despite national support in the form of grants provided by National Science Foundation, National Center for Information and Technology and legislation passed such as the Deficit Reduction Act of 2005 that encourages women to enter the STEM fields, the number of women actually graduating in these fields is surprisingly low. This research study focuses on a robotics competition and its ability to engage female adolescents in STEM curricula. Data have been collected to help explain why young women are reticent to take technology or engineering type courses in high school and college. Factors that have been described include attitudes, parental support, social aspects, peer pressure, and lack of role models. Often these courses were thought to have masculine and "nerdy" overtones. The courses were usually majority male enrollments and appeared to be very competitive. With more female adolescents engaging in this type of competitive atmosphere, this study gathered information to discover what about the competition appealed to these young women. Focus groups were used to gather information from adolescent females who were participating in the First Lego League (FLL) and CEENBoT competitions. What enticed them to participate in a curriculum that data demonstrated many of their peers avoided? FLL and CEENBoT are robotics programs based on curricula that are taught in afterschool programs in non-formal environments. These programs culminate in a very large robotics competition. My research questions included: What are the factors that encouraged participants to participate in the robotics competition? What was the original enticement to the FLL and CEENBoT programs? What will make participants want to come back and what are the participants' plans for the future? My research mirrored data of previous findings such as lack

    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.

    The current study aimed to compare the prevalence, stability, and psychosocial correlates of DSM-IV-TR and DSM-5 eating disorders, in a population-based sample of male and female adolescents followed prospectively from 14 to 20 years of age. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective, population-based cohort study that has followed participants from prebirth to young adulthood. Detailed self-report questionnaires were used to assess eating disorder symptoms when participants were aged 14, 17, and 20 years. Comparisons between DSM-IV-TR and DSM-5 were conducted using McNemar chi-square tests and Fisher's exact tests. Changes in eating disorder prevalence over time were considered using generalized estimating equations. Eating disorder prevalence rates were significantly greater when using DSM-5 than DSM-IV-TR criteria, at all time points for females and at age 17 only for males. "Unspecified"/"other" eating disorder diagnoses were significantly less common when applying DSM-5 than DSM-IV-TR criteria, but still formed 15% to 30% of the DSM-5 cases. Diagnostic stability was low for all disorders, and DSM-5 binge eating disorder or purging disorder in early adolescence predicted DSM-5 bulimia nervosa in later adolescence. Cross-over from binge eating disorder to bulimia nervosa was particularly high. Regardless of the diagnostic classification system used, all eating disorder diagnoses were associated with depressive symptoms and poor mental health quality of life. These results provide further support for the clinical utility of DSM-5 eating disorder criteria, and for the significance of binge eating disorder and purging disorder.

    Female investment during reproduction may reduce survivorship due to increased predation risk. During pregnancy, the locomotor performance of gravid females might be diminished due to the additional weight acquired. In addition, egg production may also increase thermoregulatory, metabolic and physiological costs. Also, pregnant females have greater potential fitness and should take fewer risks. Thus, females should ponder their reproductive state when considering their behavioural responses under risky situations. Here, we examine how reproductive state influence risk-taking behaviour in different contexts in female Spanish terrapins (Mauremys leprosa). We simulated predator attacks of different risk levels and measured the time that the turtles spent hiding entirely inside their own shells (i.e. appearance times). We also assessed the subsequent time after emergence from the shell that the turtles spent immobile monitoring for predators before starting to escape actively (i.e. waiting times). Likewise, we performed a novel-environment test and measured the exploratory activity of turtles. We found no correlations between appearance time, waiting time or exploratory activity, but appearance times were correlated across different risk levels. Only appearance time was affected by the reproductive state, where gravid females reappeared relatively later from their shells after a predator attack than non-gravid ones. Moreover, among gravid females, those carrying greater clutches tended to have longer appearance times. This suggests that only larger clutches could affect hiding behaviour in risky contexts. In contrast, waiting time spent scanning for predators and exploratory activity were not affected by the reproductive state. These differences between gravid and non-gravid females might be explained by the metabolic-physiological costs associated with egg production and embryo maintenance, as well as by the relatively higher potential fitness of gravid females.

    Adolescence is a period of major physical, hormonal, and psychological change. It is also characterized by a significant increase in the incidence of psychopathologies and this increase is gender-specific. Likewise, stress during adolescence is associated with the development of psychiatric disorders later in life. Previously, using a rat model of psychogenic stress (exposure to predator odor followed by placement on an elevated platform) during the pre-pubertal period (postnatal days 28–30),...

    There have been rapid advances in understanding a broad range of changes in brain structure and function during adolescence, and a growing interest in identifying which of these neurodevelopmental changes are directly linked with pubertal maturation—at least in part because of their potential to provide insights into the numerous emotional and behavioral health problems that emerge during this developmental period. This review focuses on what is known about the influence of puberty on white matter development in adolescence.We focus on white matter because of its role in providing the structural architectural organization of the brain and as a structural correlate of communication within complex neural systems. We begin with a review of studies that report sex differences or sex by age interactions in white matter development as these findings can provide, although indirectly,information relevant to puberty-related changes. Studies are also critically reviewed based on methodological procedures used to assess pubertal maturation and relations with white matter changes. Findings are discussed in light of their implications for the development of neural systems underlying the regulation of emotion and behavior and how alterations in the development of these systems may mediate risk for affective disorders in vulnerable adolescents.

    Thyroidectomy induces pancreatic edema and immune cells infiltration similarly to that observed in pancreatitis. In spite of the controverted effects of hypothyroidism on serum glucose and insulin concentrations, the number and proliferation of Langerhans islet cells as well as the presence of extracellular matrix are affected depending on the islet size. In this study, we evaluated the effect of methimazole-induced hypothyroidism on the vascularization and immune cells infiltration into islets. A general observation of pancreas was also done. Twelve Chinchilla-breed female adult rabbits were divided into control (n = 6) and hypothyroid groups (n = 6, methimazole, 0.02% in drinking water for 30 days). After the treatment, rabbits were sacrificed and their pancreas was excised, histologically processed, and stained with Periodic Acid-Schiff (PAS) or Masson's Trichrome techniques. Islets were arbitrarily classified into large, medium, and small ones. The external and internal portions of each islet were also identified. Student-t-test and Mann-Whitney-U test or two-way ANOVAs were used to compare variables between groups. In comparison with control rabbits, hypothyroidism induced a strong infiltration of immune cells and a major presence of collagen and proteoglycans in the interlobular septa. Large islets showed a high vascularization and immune cells infiltration. The present results show that hypothyroidism induces pancreatitis and insulitis. PMID:26175757

    Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, accounting for the large majority of cervical cancer and anogenital warts cases. Two HPV vaccines are currently licensed and recommended for women and girls. However, vaccination rates have been suboptimal, with evidence of disparities influencing both uptake and series completion among African American and Hispanic adolescents. There has been a dearth of theory-based, behavioral interventions targeted to prevent HPV infection and increase HPV vaccine uptake among urban adolescents. This article describes the development of two skills-based intervention curricula aimed to increase HPV prevention and vaccination among low-income urban adolescent females 9 to 18 years old. Guided by the theory of planned behavior, elicitation research was conducted to elucidate the social psychological factors that underlie HPV vaccination intentions (N = 141). The findings were subsequently used to identify theoretical mediators of behavioral change to drive the intervention. Culturally relevant strategies to promote HPV vaccination were translated into the curricula content. Both curricula were designed to motivate and empower participants to reduce risk of being infected with HPV. Targeting theoretical mediators of behavioral change, derived from the voices of the community, may prove to be successful in increasing HPV vaccination and preventing HPV. PMID:23099659

    2013-01-01

    The purpose of this study was two-fold: to determine the relationship between ethnic identity and self-esteem as dimensions of one's self-concept; and to determine if differences exist among one's ethnicity, ethnic identity, and/or self-esteem when examining at-risk eating disordered behaviors. A total of 893 urban adolescent females completed three behavioral subscales: the Eating Disorder Inventory, Rosenberg's Self-Esteem Scale, and Phinney's Multigroup Ethnic Identity Measure. As hypothesized, ethnic identity was significantly associated with self-esteem to form one's self-concept. When compared to Mexican American and White females, only Black females who were in the higher ethnic identity and self-esteem categories had significantly lower at-risk eating disordered scores. Our findings suggest eating disorder status in Mexican American and White females may not be associated as much with ethnic identity as with other acculturation and self-concept factors. Further, this study demonstrated ethnicity, self-esteem, and ethnic identity play significant roles in eating disorder risks.

    Communal nesting (CN), an early social enrichment procedure in which multiple females rear the offspring in a single nest, increases maternal care levels received by offspring and interaction with peers. It has been shown that male mice reared under CN conditions show increased social competence and propensity to social interactions at adulthood. In the present study we investigated long-term behavioural effects of CN on female offspring. Mouse pups were reared under two different experimental conditions: standard nesting (SN, where single mother rears her pups) and CN (three females rearing their pups in a single nest). At adulthood CN and SN virgin females underwent three different behavioural tests: (i) maternal induction following presentation of foster pups; (ii) social recognition test in which ultrasound vocalizations (USVs) and social investigation behaviour emitted by a resident female in the presence of a female partner were recorded; (iii) zero-maze to analyze anxiety profiles. CN females showed (i) decreased licking response in the maternal induction test accompanied by an increased sniffing response; (ii) decreased of social interest towards a novel partner (during the Retest Different phase), and decreased USV emission rate in the social recognition test; CN and SN females did not differ in the emotional responses measured in the zero-maze apparatus. As a whole these data suggest that CN rearing render female mice less reactive to social novelty. PMID:18940203

    Full Text Available Abstract 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.

    Assessments of adolescents' smoking intentions indicate that many are susceptible to smoking initiation because they do not have resolute intentions to abstain from trying smoking in the future. Although researchers have developed personality and affect-related risk factor profiles to understand risk for the initiation of substance use and abuse (e.g., alcohol), few have examined the extent to which these risk factors are related to the tobacco use intentions of adolescents who have yet to try tobacco smoking. The objective of this study was to examine the relationships between personality and affect-related risk factors measured by the Substance Use Risk Profile Scale (SURPS) and smoking intentions in a sample of adolescents who have not experimented with tobacco smoking. Data is based on responses from 1352 participants in the British Columbia Adolescent Substance Use Survey (56% female, 76% in Grade 8) who had never tried smoking tobacco. Of these 1352 participants, 29% (n=338) were classified as not having resolute intentions to not try smoking. Generalized estimating equations were used to examine the relationship between each SURPS dimension (Anxiety Sensitivity, Hopelessness, Impulsivity and Sensation Seeking) and the intention to try cigarettes in the future. Hopelessness (AOR 1.06, 95% CI [1.03, 1.10], p<.001), Impulsivity (AOR 1.07 [1.03, 1.11], p<.001) and Sensation Seeking (AOR 1.05 95% CI [1.02, 1.09], p<.01) had independent statistically significant associations with having an intention to try smoking. These findings may be used to inform a prevention-oriented framework to reduce susceptibility to tobacco smoking. PMID:26803399

    There are many hypotheses regarding factors that may encourage female students to pursue careers in the physical sciences. Using multivariate matching methods on national data drawn from the Persistence Research in Science and Engineering (PRiSE) project (n=7505), we test the following five commonly held beliefs regarding what factors might impact females’ physical science career interest: (i) having a single-sex physics class, (ii) having a female physics teacher, (iii) having female scientist guest speakers in physics class, (iv) discussing the work of female scientists in physics class, and (v) discussing the underrepresentation of women in physics class. The effect of these experiences on physical science career interest is compared for female students who are matched on several factors, including prior science interests, prior mathematics interests, grades in science, grades in mathematics, and years of enrollment in high school physics. No significant effects are found for single-sex classes, female teachers, female scientist guest speakers, and discussing the work of female scientists. However, discussions about women’s underrepresentation have a significant positive effect.

    2012-04-01

    The purpose of this study was to identify factors that affect the self-care behaviour of female high school students with dysmenorrhoea. This cross-sectional study utilized a questionnaire-based survey to understand the self-care behaviour of female high school students dysmenorrhoeal, along with the factors that affect this behaviour. A cluster random sampling method was adopted and questionnaires were used for data collection. Study participants experienced a moderate level of discomfort from dysmenorrhoea, and perceived dysmenorrhoea as serious. This investigation finds that cues to action raised perceived susceptibility to dysmenorrhoea and the perceived effectiveness of self-care behaviour and, therefore, increased the adoption of self-care behaviour. Hence, school nurses should offer female high school students numerous resources to apply correct self-care behaviour.

    Given the lack of literature on Undergraduate African American females in the sciences (UAAFS), this study sought to explicate their experiences at one large, predominantly White, Research I institution in the southwestern United States. In particular, the purpose of this study was to identify factors that affect the academic success and persistence of Black females in the natural and physical sciences. Data was collected via in-depth, semi-structured interviews with 15 Black female science majors. Findings from this study identified several supportive mechanisms for academic success: family, religion, teaching assistants and friends. Also identified were seven barriers to academic success: employment, lack of diversity, cultural dissonance, unwelcoming Research I environment, faculty, advisors, classmates, and lab groups. Further, an analysis of students' responses revealed numerous instances of racial and gender micro-aggressions. Recommendations are provided to address factors identified as affecting student academic success and persistence as well as a culture of micro-aggressive behavior.

    Sex is a motive force bringing a man and a woman into intimate contact. Sexuality is a central aspect of being human throughout life and encompasses sex, gender identities and roles, sexual orientation, eroticism, pleasure, intimacy, and reproduction. Sexuality is experienced and expressed in thoughts, fantasies, desires, beliefs, attitudes, values, behaviors, practices, roles and relationships. Though generally, women are sexually active during adolescence, they reach their peak orgasmic frequency in their 30 s, and have a constant level of sexual capacity up to the age of 55 with little evidence that aging affects it in later life. Desire, arousal, and orgasm are the three principle stages of the sexual response cycle. Each stage is associated with unique physiological changes. Females are commonly affected by various disorders in relation to this sexual response cycle. The prevalence is generally as high as 35-40%. There are a wide range of etiological factors like age, relationship with a partner, psychiatric and medical disorders, psychotropic and other medication. Counseling to overcome stigma and enhance awareness on sexuality is an essential step in management. There are several effective psychological and pharmacological therapeutic approaches to treat female sexual disorders. This article is a review of female sexuality. PMID:26330647

    Oxytocin has a modulatory role in natural and drug reward processes. While the role of oxytocin in pair bonding and reproduction has been extensively studied, sex differences in conditioned and unconditioned behavioral responses to oxytocin treatment have not been fully characterized. Here, we determined whether male and female rats would show similar dose response curves in response to acute oxytocin on measures of locomotor activity, sucrose seeking, and sucrose intake. Male and freely cycling female rats received vehicle or oxytocin (0.1, 0.3, 1, 3 mg/kg, IP) injections before behavioral tests designed to assess general motor activity, as well as sucrose self-administration and seeking. Lower doses of oxytocin decreased motor activity in a novel environment in females relative to males. Likewise, lower doses of oxytocin in females decreased responding for sucrose during maintenance of sucrose self-administration and reinstatement to sucrose-conditioned cues. However, sucrose seeking in response to a sucrose prime was only decreased by the highest oxytocin dose in both sexes. In general, oxytocin had similar effects in both sexes. However, females were more sensitive to lower doses of oxytocin than males. These findings are consistent with the notion that oxytocin regulates many of the same behaviors in males and females, but that the effects are typically more profound in females. Therapeutic use of oxytocin should include sex as a factor in determining dose regimens. PMID:25647756

    Little is known about the impact of early-life stressors such as parental loss on cognitive-affective processing during adolescence, especially in regions chronically affected by war and armed conflict. Here, we tested 72 male adolescents living in Northern Uganda (ages 14-19), 52 of whom still had both of their parents and 20 participants who had experienced parental loss. Participants completed a classic color-naming Stroop task as well as an affective interference task, the opposite emotions test (OET). Adolescents with parental loss showed a decrease in performance over time, especially on the Stroop task. Critically, this decrement in performance was positively associated with reported symptoms of trauma, but only in the parental loss group. The current data suggest a difficulty in maintaining cognitive control performance in youths with experience of parental loss. The findings are discussed in relation to traumatic stress and mental health in post-conflict regions. PMID:25899130

    Estrogenic chemicals are able to alter mammary gland development in female rodents, but little is known on the effects of anti-androgens and mixtures of endocrine disrupting chemicals (EDCs) with dissimilar modes of action. Pregnant rat dams were exposed during gestation and lactation to mixtures...... of environmentally relevant EDCs with estrogenic, anti-androgenic or dissimilar modes of action (TotalMix) of 100-, 200- or 450-fold high end human intake estimates. Mammary glands of prepubertal and adult female and male offspring were examined. Oestrogens increased mammary outgrowth in prepubertal females...... and the mRNA level of matrix metalloproteinase-3, which may be a potential biomarker for increased outgrowth. Mixtures of EDCs gave rise to ductal hyperplasia in adult males. Adult female mammary glands of the TotalMix group showed morphological changes possibly reflecting increased prolactin levels...

    Loss of control eating confers risk for excess weight gain and exacerbated disordered eating. Affect theory proposes that loss of control eating is used to cope with negative mood states. Self-report data suggest that negative affect may contribute to the etiology of loss of control eating, but this theory has not been well-tested using laboratory paradigms. We examined associations between pre-meal affective states and intake during a laboratory test meal. One-hundred and ten adolescent girl...

    Full Text Available Abstract Introduction The differential allocation hypothesis (DAH predicts that individuals should adjust their parental investment to their current mate’s quality. Although in principle the DAH holds for both sexes, male adjustment of parental investment has only been tested in a few experimental studies, revealing contradictory results. We conducted a field experiment to test whether male blue tits (Cyanistes caeruleus allocate their parental effort in relation to female ornamentation (ultraviolet colouration of the crown, as predicted by the DAH. Results We reduced the UV reflectance in a sample of females and compared parental care by their mates with that of males paired to sham-manipulated control females. As predicted by the DAH our results demonstrate that males paired with UV-reduced females invested less in feeding effort but did not defend the chicks less than males paired with control females. Conclusions To our knowledge, this is one of the first studies providing support for male differential allocation in response to female ornamentation.

    Full Text Available The present work aims to reflect on the influence of HIV / AIDS on social relations, sexuality and adolescent affectivity. We conducted a literature review and subsequent theoretical discussion on the topic, with the methodology of qualitative analysis of texts and scientific articles. The findings of the study demonstrated that it is necessary to fully consider the various psychosocial aspects of this dynamic, since the psychological aspects significantly influence disease progression and quality of life of HIV patient. For adolescents, this influence becomes even greater, because puberty is a specific stage of biological development, emotional and social, where social interaction plays an important role for the construction of the subject's personality. It is hoped that this study may contribute to the reflection on the importance of creating themselves coping strategies and health care interventions geared to this particular group, especially with regard to the psychologist, who should seek to accommodate these demands subjects, contributing to a healthy psychosocial development, considering its specific features.

    This study examined various psychometric properties of the items comprising the shame and guilt scales of the Test of Self-Conscious Affect-Adolescent (TOSCA-A) in a group children between 8 and 11 years of age. A total of 699 children (367 females and 332 males) completed these scales, and also measures of depression and empathy. Confirmatory factor analysis (CFA) provided support for an oblique two-factor model, with the originally proposed shame and guilt items comprising shame and guilt factors, respectively. There was good internal consistency reliability for the shame and guilt scales, with omega coefficient values of 0.77 and 0.81 for shame and guilt, respectively. Also, shame correlated with depression symptoms positively (0.34, p empathy (-0.07, ns). Guilt correlated with depression symptoms negatively (-0.28, p empathy positively (0.13. p children with a separate group of adolescents (320 females and 242 males), based on the chi-square difference test, supported full metric invariance, the intercept invariance of 17 of the 30 shame and guilt items, and higher latent mean scores among children for both shame and guilt. The non-equivalency for intercepts and mean scores were of small effect sizes. Comparisons based on the difference in root mean squared error of approximation values supported full measurement invariance and no group difference for latent mean scores. The findings in the current study support the use of the TOSCA-A in children and the valid comparison of scores between children and adolescents, thereby opening up the possibility of evaluating change in the TOSCA-A shame and guilt factors over these developmental age groups.

    Research in context: Due to lack of biological markers, diagnosis and treatment of psychiatric disorders are subjective. There is utmost urgency to identify biomarkers for clinics, research, and drug development. We found that XIST and KDM5C gene expression may be used as a biological marker for diagnosis of major affective disorders in a significantly large subset of female patients from the general population. Our studies show that over-expression of XIST and some X-linked escapee genes may be a common mechanism for development of psychiatric disorders between the patients with rare genetic diseases (XXY or XXX and the general population of female psychiatric patients.

    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.

    The purpose of this longitudinal study was to examine the role of peer groups and sex in adolescents' task values and physical activity. The participants were 330 Finnish Grade 6 students (173 girls, 157 boys), who responded to questionnaires that assessed physical education task values during the spring semester (Time 1). Students' physical activity was assessed one year later (Time 2). The results indicated that adolescent peer groups were moderately homogeneous in terms of task values toward physical education and physical activity. Girls' peer groups were more homogeneous than those of boys in regards to utility and attainment values. Furthermore, the results for both girls and boys showed that particularly intrinsic task value typical for the peer group predicted group members' physical activity. The findings highlight the important role of peer group membership as a determinant of future physical activity. PMID:21526593

    Because an attractive appearance is so essential to the feminine gender role, the search for beauty causes special adjustment problems for adolescent girls. Psychologically they suffer from negative body image, lowered self-esteem, and achievement conflicts. Physically their health is undermined by current beauty norms which foster eating disorders, cosmetic acne, and breast surgery. The effects of physical fitness programs, the role of the media, and the influence of changing gender roles are also discussed. PMID:6235678

    2013-10-01

    Achieving a sense of purpose during adolescence is a developmental asset; however, searching for that purpose may be a developmental stressor. Supportive parent-child relationships may help youth during this stressful experience. The present study included 207 female students in the sixth, eighth, and tenth grades from two competitive private schools. Searching for purpose negatively predicted self-esteem. Hierarchical linear regression examined moderating effects of parental trust and alienation on searching for purpose as a predictor of self-esteem. Parental alienation significantly moderated the association between search for purpose and girls' self-esteem; conversely, parental trust did not moderate the association. Results suggest that parent-child relationships characterized by high levels of parental alienation may exacerbate the pernicious effects of search for purpose. Person-based analyses found four clusters corresponding to Foreclosed Purpose, Diffused Purpose, Uncommitted Purpose/Moratorium, and Achieved Purpose. We discuss implications for practice and research based on these results. PMID:24011100

    This study investigates morphological and biochemistry effects of binge ethanol consumption in parotid (PG) and submandibular (SG) salivary glands of rats from adolescence to adulthood. Female Wistar rats (n = 26) received ethanol at 3 g/kg/day (20% w/v) for 3 consecutive days/week from the 35th until the 62nd day of life. Animals were treated in two periods: 1 week (G1) and 4 weeks (G2), with a control (treated with distilled water) and an ethanol group to each period. In morphological analysis, morphometric and immunohistochemistry evaluation for smooth muscle actin (αSMA), cytokeratin-18 (CK-18), and vimentin (VIM) were made. Biochemical changes were analyzed by concentration of nitrites and levels of malondialdehyde (MDA). The difference between groups in each analysis was evaluated by Mann-Whitney U test or Student's t-test (p ≤ 0.05). PG showed, at one week of ethanol exposure, lower CK-18 and α-SMA expression, as well as MDA levels. After four weeks, lower CK-18 and higher MDA levels were observed in PG exposed to ethanol, in comparison to control group. SG showed lower α-SMA expression after 1 and 4 weeks of ethanol exposure as well as higher MDA levels after 1 week. Ethanol binge consumption during adolescence promotes tissue and biochemical changes with only one-week binge in acinar and myoepithelial PG cells. PMID:27579155

    We examined the effects of 16 weeks of training on diurnal pattern of salivary alpha-amylase (sAA), cortisol, and the ratio of sAA over cortisol (AOC) in 12 national adolescent female tennis players. Stress and recovery were also evaluated using the Recovery-Stress-Questionnaire for Athletes-RESTQ-Sport. Data were collected after a 2-week rest (January, W0), and 4 months after W0 (W16). Subjects collected five saliva samples throughout a day. While all participants displayed the previously shown decrease after awakening in adolescents at W0, they showed a rise in the alpha-amylase awakening response and a higher alpha-amylase activity output (pcortisol we found subjects having a low overall output of salivary cortisol (pSport-specific recovery score. Our findings offer support for the hypothesis that increase of training load during the study period induced asymmetry activation between the two stress systems, in relation to psychological alterations and performance decrease. These results provide encouragement to continue exploring the impact of training program using a psychobiological approach among young athletes in order to prevent fatigue and preserve the health of these athletes.

    The Sexual Competence and Interaction Competence in Youth is a self-report questionnaire that aims to measure sexual competence and interaction competence in adolescents. The study sample consisted of 276 female undergraduate students (M = 20.95 years, SD = 2.00 years). The factor structure of the questionnaire was calculated on full sample data. A subsample was used to calculate the validity and internal consistency (N = 236; M = 20.88 years, SD = 1.96). The test-retest reliability was also calculated in a subsample (N = 82; M = 21.45 years, SD = 1.74 years). On the basis of an exploratory factor analysis, 8 factors were extracted: (a) communication about sex, (b) refusing sex, (c) positive sexual attitudes, (d) male role in sexual interaction, (e) contraceptive use, (f) not suppressing problems and desires regarding sex, (g) sexual assertiveness, and (h) sexual hedonism. The subscales possess adequate internal consistency and moderate to excellent test-retest reliability. A higher order principal component analysis revealed a 2-factor structure that appears to adequately represent the sexual competence and interaction competence constructs. Furthermore, convergent and discriminant validity were considered to be good. The results indicate that the Sexual Competence and Interaction Competence in Youth may be a useful instrument to measure sexual and interaction competence among adolescents. PMID:24949740

    Full Text Available Abstract Background Knee injuries in football are common regardless of age, gender or playing level, but adolescent females seem to have the highest risk. The consequences after severe knee injury, for example anterior cruciate ligament (ACL injury, are well-known, but less is known about knee injury prevention. We have designed a cluster randomized controlled trial (RCT to evaluate the effect of a warm-up program aimed at preventing acute knee injury in adolescent female football. Methods In this cluster randomized trial 516 teams (309 clusters in eight regional football districts in Sweden with female players aged 13–17 years were randomized into an intervention group (260 teams or a control group (256 teams. The teams in the intervention group were instructed to do a structured warm-up program at two training sessions per week throughout the 2009 competitive season (April to October and those in the control group were informed to train and play as usual. Sixty-eight sports physical therapists are assigned to the clubs to assist both groups in data collection and to examine the players' acute knee injuries during the study period. Three different forms are used in the trial: (1 baseline player data form collected at the start of the trial, (2 computer-based registration form collected every month, on which one of the coaches/team leaders documents individual player exposure, and (3 injury report form on which the study therapists report acute knee injuries resulting in time loss from training or match play. The primary outcome is the incidence of ACL injury and the secondary outcomes are the incidence of any acute knee injury (except contusion and incidence of severe knee injury (defined as injury resulting in absence of more than 4 weeks. Outcome measures are assessed after the end of the 2009 season. Discussion Prevention of knee injury is beneficial for players, clubs, insurance companies, and society.

  20. A study of the factors affecting the attitudes of young female students toward chemistry at the high school level

    Science.gov (United States)

    Banya, Santonino K.

    Chemistry is a human endeavor that relies on basic human qualities like creativity, insights, reasoning, and skills. It depends on habits of the mind: skepticism, tolerance of ambiguity, openness to new ideas, intellectual honesty, curiosity, and communication. Young female students begin studying chemistry curiosity; however, when unconvinced, they become skeptical. Researches focused on gender studies have indicated that attitudes toward science education differ between males and females. A declining interest in chemistry and the under representation of females in the chemical science was found (Jacobs, 2000). This study investigated whether self-confidence toward chemistry, the influence of role models, and knowledge about the usefulness of chemistry were affecting the attitudes toward chemistry, of 183 high school young females across the United States. The young female students surveyed, had studied chemistry for at least one year prior to participating in the study during the fall semester of 2003. The schools were randomly selected represented diverse economic backgrounds and geographical locations. Data were obtained using Chemistry Attitude Influencing Factors (CAIF) instrument and from interviews with a focus group of three young female students about the effect of self-confidence toward chemistry, the influence of role models, and knowledge about the usefulness of chemistry on their decision to study chemistry. The CAIF instrument consisted of a 12-items self-confidence questionnaire (ConfiS), 12-items each of the influence of role models (RoMoS) and knowledge about usefulness of chemistry (US) questionnaire. ConfiS was adopted (with permission) from CAEQ (Coll & Dalgety, 2001), and both RoMoS and US were modified from TOSRA (Fraser, 1978), public domain document. The three young female students interviewed, gave detailed responses about their opinions regarding self-confidence toward chemistry, the influence of role models, and knowledge about the

    Full Text Available Background. Open family discussion on reproductive health (RH issues often leads to increased awareness on RH matters and reduces risky behaviors among adolescents. This study was conducted to assess factors affecting parent-adolescent discussion on RH issues in Harar, Ethiopia. Methods. A cross-sectional survey using face to face interview supplemented with focus group discussion (FGD was conducted on 751 randomly selected parents of 10–19-year-old adolescents. Data was analyzed using SPSS version 15. Results. More than one-fourth (28.76% of parents reported discussing RH issues with their adolescents during the last six months. In the logistic regression, parents who have demonstrated good RH knowledge and positive attitude towards RH were almost six times and seventy percent (AOR 5.69, 95% CI: 3.67–8.82; AOR 1.70, 95% CI: 1.08–2.68 higher in discussing RH with their adolescents than their counterparts, respectively. Conclusion. Parent-adolescent discussion about RH issues rarely occurs and is bounded by lack of knowledge, sociocultural norms, and parental concern that discussion would encourage premarital sex. Reproductive health programs should target on improving awareness of parents and addressing sociocultural norms surrounding reproductive health issues.

    Vitellogenin (Vg), a yolk protein precursor, is the primary egg nutrient source involved in insect reproduction and embryo development. The Cotton Boll weevil (CBW) Anthonomus grandis Boheman, the most important cotton pest in Americas, accumulates large amounts of Vg during reproduction. However, the precise role of this protein during embryo development in this insect remains unknown. Herein, we investigated the effects of vitellogenin (AgraVg) knockdown on the egg-laying and egg viability in A. grandis females, and also characterized morphologically the unviable eggs. AgraVg transcripts were found during all developmental stages of A. grandis, with highest abundance in females. Silencing of AgraVg culminated in a significant reduction in transcript amount, around 90%. Despite this transcriptional reduction, egg-laying was not affected in dsRNA-treated females but almost 100% of the eggs lost their viability. Eggs from dsRNA-treated females showed aberrant embryos phenotype suggesting interference at different stages of embryonic development. Unlike for other insects, the AgraVg knockdown did not affect the egg-laying ability of A. grandis, but hampered A. grandis reproduction by perturbing embryo development. We concluded that the Vg protein is essential for A. grandis reproduction and a good candidate to bio-engineer the resistance against this devastating cotton pest. PMID:27419079

  3. An Investigation of Factors Affecting Elementary Female Student Teachers' Choice of Science as a Major at College Level in Zimbabwe

    Mlenga, Francis

    This article focuses on factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe. In Sub-Saharan Africa, there has been an unprecedented expansion in education in the last 2 decades. This reflects the broad recognition that education contributes to national development. This expansion has not been matched with equal access and opportunity to education. The education of females still lags behind that of males in most developing countries, and in Sub-Saharan Africa in particular (Hyde, 1989). Fewer girls than boys study science at both secondary and college levels. The study took place in Zimbabwe at Mkoba Teachers' College. Two groups of elementary female student teachers participated in the study, namely science majors and nonscience majors. Ten science majors and nine nonscience majors took part in individual interviews. For focus group interviews, there were three groups of six each from science and nonscience majors. The study was conducted between May 2004 and July 2004. Out-of-school experiences, culture, and attitudes toward science emerged as factors affecting female student teachers' choice of science as a major. A number of implications have been discussed as well as suggestions for further research. Limitations of the study have been analyzed as well.

    2010-08-01

    Experimental testing and retrospective examination of breeding records were used to examine the influence of sex composition and/or size of males' birth litters on female mate-choice. Sexually naïve female prairie voles (Microtus ochrogaster) avoided males derived from all-male litters, but showed no preference for, or aversion to, males from single-male litters or from more typical mixed-sex litters. Examination of the pregnancy status of females after two weeks of pairing with a male allowed us to estimate the probabilites of a pups' intrauterine position relative to siblings for various litter sizes. The typical prairie vole pup derived from a mixed-sex litter comprised of 4.4 pups, and had a 13% chance of being isolated from siblings in utero and a 22% chance of being between siblings in utero. Pups from single-sex litters tended to be larger at weaning than did pups from mixed-sex litters; however, male size did not influence female choice behavior. These results suggest that some aspect of the perinatal experience of prairie vole pups from single sex litters can influence social interactions later in life.

    Full Text Available Aim: Hypertension, obesity, insulin resistance and lipid levels are risk factors for cardiovascular disease. The association of cardiovascular risk with C-reactive protein and homocysteine has been debated for decades. Resistin and microalbuminuria are presumed to be associated with diabetes mellitus, insulin resistance and cardiovascular disease. The objective of our study was to investigate the relationship of microalbuminuria with antropometric and metabolic parameters, C-reactive protein, homocyteine and resistin in non-diabetic hypertensive females. Methods: We conducted a randomized study including 37 female non-diabetic hypertensives without microalbuminuria and 47 female non-diabetic hypertensive patients with microalbuminuria. We made comparisons of anthropometric and metabolic parameters, C-reactive protein, homocysteine, insulin resistance index and resistin between the groups. Results: C-reactive protein, homocysteine, resistin, insulin levels and homeostasis model assessment of insulin resistance were higher in hypertensives with microalbuminuria than in hypertensives without microalbuminuria (all p<0.05. Conclusion: We found that microalbuminuria may have an influence on C-reactive protein, homocysteine and resistin levels in non-diabetic hypertensives. We also think that insulin and insulin resistance may also be related with microalbuminuria in non-diabetic hypertensive female patients. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 172-6

    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.

    Study Design. The Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST) included skeletally immature high-risk patients with adolescent idiopathic scoliosis (AIS) with moderate curve sizes (20°– 40°). BrAIST was a multicenter, controlled trial using both randomized and preference treatment arms into either an observation group or a brace treatment group. Objective. The aim of this study was to analyze and compare body image and quality-of-life (QOL) in female AIS patients who were observed or treated with a brace. Summary of Background Data. Brace treatment is an effective means for controlling progressive scoliosis and preventing the need for surgery, but there is no consensus regarding the effect of brace treatment on body image or on QOL in adolescents with AIS. Methods. Data from female BrAIST patients in the randomized (n = 132) or preference (n = 187) arms and were observed (n = 120) or brace treated (n = 199) were analyzed. Patients completed the Spinal Appearance Questionnaire (SAQ) and the Pediatric Quality of Life Inventory (PedsQOL) 4.0 Generic Scales at baseline and 6 month follow-up visits up to 2 years. Items on the SAQ measured three body image constructs (self, ideal, and overall). The PedsQOL measured health, activities, feelings, social factors, and school. Results. . In general, there were no significant differences within or between study arms or treatments regarding body image or QOL through 2 years of follow-up. Poorer body image was significantly correlated with poorer QOL during the first 2 years of follow-up regardless of study arm or treatment. Patients who crossed-over to a different treatment and patients with largest Cobb angles ≥ 40 degrees had significantly poorer body image, in particular self-body image, compared with those that did not. Conclusion. This study does not support findings from previous research indicating that wearing a brace has a negative impact on or is negatively impacted by body image or

    Full Text Available The relative importance of genetic and socio-cultural influences contributing to the success of east Africans in endurance athletics remains unknown in part because the pre-training phenotype of this population remains incompletely assessed. Here cardiopulmonary fitness, physical activity levels, distance travelled to school and daily energy expenditure in 15 habitually active male (13.9±1.6 years and 15 habitually active female (13.9±1.2 adolescents from a rural Nandi primary school are assessed. Aerobic capacity ([Formula: see text] was evaluated during two maximal discontinuous incremental exercise tests; physical activity using accelerometry combined with a global positioning system; and energy expenditure using the doubly labelled water method. The [Formula: see text] of the male and female adolescents were 73.9±5.7 ml(. kg(-1. min(-1 and 61.5±6.3 ml(. kg(-1. min(-1, respectively.

    Full Text Available During development, environmental estrogens are able to induce an estrogen mimetic action that may interfere with endocrine and neuroendocrine systems. The present study investigated the effects on the reproductive function in female mice following developmental exposure to pharmaceutical ethinylestradiol (EE2, the most widespread and potent synthetic steroid present in aquatic environments. EE2 was administrated in drinking water at environmentally relevant (ENVIR or pharmacological (PHARMACO doses (0.1 and 1 µg/kg (body weight/day respectively, from embryonic day 10 until postnatal day 40. Our results show that both groups of EE2-exposed females had advanced vaginal opening and shorter estrus cycles, but a normal fertility rate compared to CONTROL females. The hypothalamic population of GnRH neurons was affected by EE2 exposure with a significant increase in the number of perikarya in the preoptic area of the PHARMACO group and a modification in their distribution in the ENVIR group, both associated with a marked decrease in GnRH fibers immunoreactivity in the median eminence. In EE2-exposed females, behavioral tests highlighted a disturbed maternal behavior, a higher lordosis response, a lack of discrimination between gonad-intact and castrated males in sexually experienced females, and an increased anxiety-related behavior. Altogether, these results put emphasis on the high sensitivity of sexually dimorphic behaviors and neuroendocrine circuits to disruptive effects of EDCs.

    This research examines the ontogenic patterns of changes in growth during adolescence, pelvis variations and growth during twenties and thirties of age, structural remodeling of pelvis related to childbirth and relationship of pelvis area with physique based on the cross-sectional data on 391 females from the state of Haryana. Peak growth velocity for body height and breadths of skeletal traits occurred between 11 and 12 years, much before mean age of menarche at 13.5 years; while for body weight and body mass index (BMI) occurred between 14 and 15 years, after the mean age of menarche. Untill the age 11 years, 11.87% of growth in stature was remaining, 19.37% for bi-cristal breadth, 25.96% for bi-ischial breadth and 35.82% for pelvic area. The hypothesis of critical value of pelvic width of 240mm at iliocristale for menarche to occur has been only a statistical association. Higher prevalence of malnutrition during pubertal phase than pre- and post-pubertal phases was due to greater nutritional needs during puberty. Among adult females, BMI was very poorly correlated with stature but very strongly correlated with body breadths, body breadth-stature indices and body weight. The body mass and pelvis size continued to change during 20s and first half of 30s. The continued increase of BMI was due to increase in body fat and muscle mass in females 18 years and older. To tease apart age and parturition effects on pelvis variations, the analysis showed that pelvic bones remodeling took place after the first child was born and not after the subsequent births, and it was a sign of childbirth phenotypic plasticity rather than age. Pelvis area was strongly associated with stature, BMI and age. Mean pelvic area of tall females was greater than those of medium and short stature. Females with broad shoulders had significantly greater mean pelvis area than those with narrow shoulders and medium shoulders. Females having thin/lean physique had the smallest mean pelvis area

    The current study examined internalizing symptoms, affect reactivity, and distress intolerance as prospective predictors of increases in eating disorder (ED)-attitudes during adolescence. Adolescents (n = 206) took part in a six-year longitudinal study examining the development of psychopathology. Latent growth curve analysis was used to examine associations between predictors and later ED-attitudes. Distress intolerance and internalizing symptoms were associated with ED-attitudes at baseline, but did not predict increases over time. Affect reactivity, however, was significantly associated with increases in ED-attitudes over time. Baseline affect reactivity did not interact with baseline distress intolerance to predict increases in ED-attitudes; however higher baseline internalizing symptoms interacted with distress intolerance to predict increases in ED-attitudes across adolescence. These results are among the first to document that affect reactivity alone and the combined effect of high internalizing symptoms and high distress intolerance early in adolescence are risk factors for the later development of ED-attitudes.

    Full Text Available Background: The objectives of this study were to examine (a the prevalence of overweight/obesity, and (b the relationship between body mass index (BMI, body fat percentage (BF and physical fitness in adolescent and adult female volleyball players. 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.

    Full Text Available Kleine-Levine Syndrome (KLS is a disorder characterized by a triad of periodic hypersomnia, hyperphagia, and hypersexuality. KLS, although more common in young males, it has also been seen in females. Treatment options available for its management include mood stabilisers like lithium, stimulants like amphetamines, antidepressants and other options including electroconvulsive therapy. Modafinil is one of the new stimulant medications approved for narcolepsy. Herein, we report a young female with KLS and showing favorable response to modafinil. More data is required to establish the effectiveness of modafinil in this syndrome.

    Neuropeptide Y (NPY) stimulates feeding, depresses sexual behavior, and its expression in the brain is modulated by energetic status. We examined the role of NPY in female musk shrews, a species with high energetic and reproductive demands; they store little fat, and small changes in energy can rapidly diminish or enhance sexual receptivity. Intracerebroventricular infusion of NPY enhanced acute food intake in shrews, however, NPY had little affect on sexual receptivity. The distribution of N...

    Limited research has examined HPV vaccination in Appalachia, a region with cervical cancer disparities. We analyzed 2008-2010 National Immunization Survey-Teen data for adolescent females ages 13-17 from Appalachia (n=1951) to identify correlates of HPV vaccination and reasons why their parents do not intend to vaccinate. HPV vaccine initiation was 40.8%, completion was 27.7%, and follow-through was 67.8%. Vaccination outcomes tended to be higher among females who were older, had visited their healthcare provider in the last year, or whose parents reported receiving a provider recommendation to vaccinate. Only 41.0% of parents with unvaccinated daughters intended to vaccinate in the next year. The most common reasons for not intending to vaccinate were believing vaccination is not needed or not necessary (21.5%) and lack of knowledge (18.5%). Efforts to reduce missed opportunities for vaccination at healthcare visits and address reasons why parents are not vaccinating may help increase HPV vaccination in Appalachia.

    Background: young persons are most strongly affected by displacement through political/military actions. This is also a European problem as well as an issue for the European Union. Applying the social-ecological model by Bronfenbrenner we concentrated on micro- and mesosystems of Austrian adolescents and migrant adolescents of war-affected countries.

    Methods: a questionnaire was administered to adolescents in Austria attending schools beyond the mandatory school age, yielding a sample of about 1 100 students from Austrian and immigrant background. We used analysis of variance to compare host and immigrant youth as well as regression analysis to assess the impact of risk and protective factors on youth outcomes.

    Results: we do find sex differences for protective factors and youth outcomes but few differences between immigrant and Austrian adolescents. Youth outcomes analysed were somatic symptoms, anxiety, depression, self-esteem, anti-social behaviour, substance use, and academic performance. Important risk factors turned out to be intergenerational conflict, exposure to violence, and social distance. Protective factors include family connectedness, parental monitoring, school connectedness, peer support, and neighbourhood attachment.

    Conclusions: the most important protective factor is school connectsdness. Social distance and intergenerational conflict are the dominant risk factors influencing youth outcomes. Our research leads to a better understanding of factors determining the well-being of adolescents and contributes to finding new approaches to prevent or cope with mental health problems of young immigrants. In particular it appears to be important to keep young persons in education and/or training since school connectedness influences mental health and well-being positively.

    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, the number of neurons and glia is 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 3g/kg ethanol was administered between postnatal days (P) 35-45 in a binge-like pattern, with 2days 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.

    This paper reviews research on the psychological impact of onset of menstruation (menarche). Menarche is an important event for all girls, yet there is relatively little research on this topic, and the existing research contains a number of conceptual and methodological problems. In this paper, we review attitudes toward menarche and personality characteristics of pubertal girls. Then we look at memories of menarche from late adolescents and adult women. Finally, we examine studies of the impact of timing (early and late menarche). Overall, the studies indicate that menarche is a memorable and significant event for girls. Frequently the experience is perceived negatively, but there is also a positive, integrating result to menarche. Factors influencing the psychological impact of menarche include age at time of first period, social factors, amount of preparation, and cultural factors. The paper focuses on research problems and provides suggestions for future research. PMID:6756807

    Numerous basic and epidemiological studies have connected prenatal maternal immune activation with the occurrence of schizophrenia and/or autism. Depending on subtle differences in protocols of the used animal model, a variety of behavioral abnormalities has been reported. This study investigated behavioral differences in Wistar rat offspring of both genders, exposed to the 100 μg/kg per day dose of lipopolysaccharide (LPS) in late embryogenesis (embryonic days 15 and 16), while tested at their adolescent and young adult age (postnatal days 40 and 60, respectively). Immune activation was confirmed by detecting high levels of TNF-α and IL-6 in dam blood withdrawn 2h after the first dose of LPS. The animals were assessed in three consecutive trials of locomotor activity (novelty exploration, response to i.p. saline injection and challenge with 0.5mg/kg amphetamine), Morris water maze and social interaction tests. Overt behavioral dysfunction was perceived in adult rats only, and these changes were gender-distinctive. When compared with control rats, LPS females displayed baseline hypolocomotion and a decreased reactivity to amphetamine, while LPS males exhibited spatial learning (acquisition trials) and memory (probe trial) impairments. Prenatal treatment did not affect the time spent in social interaction. As maternal exposure to LPS in late gestation resulted in behavioral changes in offspring in early adulthood, it may model schizophrenia-like, but not autism-like endophenotypes. However, lack of a potentiated response to amphetamine testified that this model could not mimic positive symptoms, but rather certain traits of cognitive dysfunction and deficit symptoms, in males and females, respectively.

    The primary purpose of this paper was to compare the epidemiology of mental health problems and self-esteem of conflict hit adolescents living in charitable seminaries with their counterparts brought up in natural homes. Substantive body of the literature illustrates the emotional and behavioral issues experienced by these adolescents. In this study, 27 adolescents from a charitable Muslim seminary and 30 adolescents from a regular school were recruited. Self-report measures and clinical interview were used to measure mental health and self-esteem. The findings indicate that adolescents in institution setting may not be having mental health and self-esteem-related issues when compared to adolescents living in intact by parent homes. While the authors acknowledge the limitations of the study, these findings need further research to examine the causes for these differences.

    Adolescence is a time of developmental changes and reorganization in the brain. It has been hypothesized that stress has a greater neurological impact on adolescents than on adults. However, scientific evidence in support of this hypothesis is still limited. We treated adolescent (4-week-old) and adult (8-week-old) rats with social instability stress for five weeks and compared the subsequent structural and functional changes to amygdala neurons.

    Full Text Available People’s thoughts often focus on the suicide victim immediately after a completed suicide. Yet, the real victims of such an event are those individuals who are left behind to cope with the aftermath of the suicide. This phenomenological psychological study explored the lived experiences of late-adolescent suicide survivors, particularly those negative experiences that seemed to worsen in the weeks and months after a significant other’s completed suicide. The research participants were five female late-adolescents (aged 17–22 years who were recruited by means of purposive sampling at a South African tertiary institution and at youth camps. Data collection consisted of collage-facilitated, face-to-face phenomenological interviews. In addition, some participants provided documentary material in the form of personal diaries, letters and poems. The data analysis was conducted according to Giorgi’s phenomenological method. The following salient experiences emerged during the data analysis: guilt, self-blame, blaming others or God, anger, loss or restriction of ‘self’, depression, suboptimal behavioural coping patterns, changes in relationship dynamics, and suicidality. The results of this study can be used by mental health professionals and caregivers to support adolescent suicide survivors effectively, in the midst of their mourning.

    The pubertal surge in gonadal hormones that occurs during adolescence may impact the long-term effects of early alcohol exposure and sex differences in drinking behavior in adulthood. We investigated this hypothesis by performing sham or gonadectomy surgeries in Long Evans rats around postnatal day (P) 20. From P35–45, males and females were given saline or 3.0 g/kg ethanol using a binge-like model of exposure (8 injections total). As adults (P100), they were trained to self-administer ethanol via a sucrose-fading procedure and then given access to different unsweetened concentrations (5–20% w/v) for 5 days/concentration. We found that during adolescence, ethanol-induced intoxication was similar in males and females that underwent sham surgery. In gonadectomized males and females, however, the level of intoxication was greater following the last injection compared to the first. During adulthood, females drank more sucrose per body weight than males and binge-like exposure to ethanol reduced sucrose consumption in both sexes. These effects were not seen in gonadectomized rats. Ethanol consumption was higher in saline-exposed females compared to males, with gonadectomy reversing this sex difference by increasing consumption in males and decreasing it in females. Exposure to ethanol during adolescence augmented ethanol consumption in both sexes, but this effect was statistically significant only in gonadectomized females. Together, these results support a role for gonadal hormones during puberty in the short- and long-term effects of ethanol on behavior and in the development of sex differences in consummatory behavior during adulthood.

  3. Influence of ghrelin and adipocytokines on bone mineral density in adolescent female athletes with amenorrhea and eumenorrheic athletes.

    2010-01-01

    Adolescent female athletes are at increased risk for low bone mineral density (BMD) secondary to exercise-induced hypogonadism. Of particular concern is that the adolescent years are also a critical time for bone accrual, and deficits incurred during this period could lead to suboptimal peak bone mass acquisition and subsequent fracture risk in later life. Although weight-bearing exercise is typically associated with an increase in BMD, amenorrheic athletes have lower BMD than eumenorrheic athletes and nonathletic controls as a consequence of low energy availability and subsequent hypogonadism. It is important to recognize that critical interactions exist between net energy availability and the hypothalamo-pituitary-gonadal (H-P-G) axis that are key to the development of a hypogonadal state when energy intake cannot keep pace with expenditure. While the link between energy availability and gonadtotropin pulsatility patterns is well established, the actual metabolic signals that link the two are less clear. Decreased energy availability in athletes is associated with decreases in fat mass, and alterations in adipokines (such as leptin and adiponectin) and fat-regulated hormones (such as ghrelin and peptide YY). These hormones impact the H-P-G axis in animal models, and it is possible that in athletes alterations in fat-related hormones signal the state of energy availability to the hypothalamus and contribute to suppression of gonadotropin pulsatility, hypothalamic amenorrhea and consequent decreased BMD. A better understanding of pathways linking low energy availability with functional hypothalamic amenorrhea and low BMD is critical for the development of future therapeutic strategies addressing these issues in amenorrheic athletes.

    Although Web-based treatments have significant potential to assess and treat difficult-to-reach populations, such as trauma-exposed adolescents, the extent that such treatments are accessed and used is unclear. The present study evaluated the proportion of adolescents who accessed and completed a Web-based treatment for postdisaster mental health symptoms. Correlates of access and completion were examined. A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context. PMID:25622071

    Philippe R Mutwa

    Full Text Available INTRODUCTION: Adherence to combination antiretroviral therapy (cART is vital for HIV-infected adolescents for survival and quality of life. However, this age group faces many challenges to remain adherent. We used multiple data sources (role-play, focus group discussions (FGD, and in-depth interviews (IDI to better understand adherence barriers for Rwandan adolescents. Forty-two HIV positive adolescents (ages 12-21 and a selection of their primary caregivers were interviewed. All were perinatally-infected and received (cART for ≥ 12 months. Topics discussed during FGDs and IDIs included learning HIV status, disclosure and stigma, care and treatment issues, cART adherence barriers. RESULTS: Median age was 17 years, 45% female, 45% orphaned, and 48% in boarding schools. We identified three overarching but inter-related themes that appeared to influence adherence. Stigma, perceived and experienced, and inadvertent disclosure of HIV status hampered adolescents from obtaining and taking their drugs, attending clinic visits, carrying their cARTs with them in public. The second major theme was the need for better support, in particular for adolescents with different living situations, (orphanages, foster-care, and boarding schools. Lack of privacy to keep and take medication came out as major barrier for adolescents living in congested households, as well the institutionalization of boarding schools where privacy is almost non-existent. The third important theme was the desire to be 'normal' and not be recognized as an HIV-infected individual, and to have a normal life not perturbed by taking a regimen of medications or being forced to disclose where others would treat them differently. CONCLUSIONS: We propose better management of HIV-infected adolescents integrated into boarding school, orphanages, and foster care; training of school-faculty on how to support students and allow them privacy for taking their medications. To provide better care and

Hence, cautious use of such medication should be advocated especially when managing couples for infertility.

  7. Gender separation increases somatic growth in females but does not affect lifespan in Nothobranchius furzeri.

    Directory of Open Access Journals (Sweden)

    Michael Graf

    Full Text Available According to life history theory, physiological and ecological traits and parameters influence an individual's life history and thus, ultimately, its lifespan. Mating and reproduction are costly activities, and in a variety of model organisms, a negative correlation of longevity and reproductive effort has been demonstrated. We are employing the annual killifish Nothobranchius furzeri as a vertebrate model for ageing. N. furzeri is the vertebrate displaying the shortest known lifespan in captivity with particular strains living only three to four months under optimal laboratory conditions. The animals show explosive growth, early sexual maturation and age-dependent physiological and behavioural decline. Here, we have used N. furzeri to investigate a potential reproduction-longevity trade-off in both sexes by means of gender separation. Though female reproductive effort and offspring investment were significantly reduced after separation, as investigated by analysis of clutch size, eggs in the ovaries and ovary mass, the energetic surplus was not reallocated towards somatic maintenance. In fact, a significant extension of lifespan could not be observed in either sex. This is despite the fact that separated females, but not males, grew significantly larger and heavier than the respective controls. Therefore, it remains elusive whether lifespan of an annual species evolved in periodically vanishing habitats can be prolonged on the cost of reproduction at all.

  8. Estradiol affects liver mitochondrial function in ovariectomized and tamoxifen-treated ovariectomized female rats

    International Nuclear Information System (INIS)

    Given the tremendous importance of mitochondria to basic cellular functions as well as the critical role of mitochondrial impairment in a vast number of disorders, a compelling question is whether 17β-estradiol (E2) modulates mitochondrial function. To answer this question we exposed isolated liver mitochondria to E2. Three groups of rat females were used: control, ovariectomized and ovariectomized treated with tamoxifen. Tamoxifen has antiestrogenic effects in the breast tissue and is the standard endocrine treatment for women with breast cancer. However, under certain circumstances and in certain tissues, tamoxifen can also exert estrogenic agonist properties. We observed that at basal conditions, ovariectomy and tamoxifen treatment do not induce any statistical alteration in oxidative phosphorylation system and respiratory chain parameters. Furthermore, tamoxifen treatment increases the capacity of mitochondria to accumulate Ca2+ delaying the opening of the permeability transition pore. The presence of 25 μM E2 impairs respiration and oxidative phosphorylation system these effects being similar in all groups of animals studied. Curiously, E2 protects against lipid peroxidation and increases the production of H2O2 in energized mitochondria of control females. Our results indicate that E2 has in general deleterious effects that lead to mitochondrial impairment. Since mitochondrial dysfunction is a triggering event of cell degeneration and death, the use of exogenous E2 must be carefully considered

    Establishment of adequate levels of sialylation is crucial for sperm survival and function after insemination; however, the mechanism for the addition of the sperm sialome has not been identified. Here, we report evidence for several different mechanisms that contribute to the establishment of the mature sperm sialome. Directly quantifying the source of the nucleotide sugar CMP-beta-N-acetylneuraminic acid in epididymal fluid indicates that transsialylation occurs in the upper epididymis. Western blots for the low-molecular-mass sialoglycoprotein (around 20-50 kDa) in C57BL/6 mice epididymal fluid reflect that additional sialome could be obtained by glycosylphosphatidylinositol-anchored sialoglycopeptide incorporation during epididymal transit in the caput of the epididymis. Additionally, we found that in Cmah (CMP-N-acetylneuraminic acid hydroxylase)-/- transgenic mice, epididymal sperm obtained sialylated-CD52 from seminal vesicle fluid (SVF). Finally, we used Gfp (green fluorescent protein)+/+ mouse sperm to test the role of sialylation on sperm for protection from female leukocyte attack. There is very low phagocytosis of the epididymal sperm when compared to that of sperm coincubated with SVF. Treating sperm with Arthrobacter ureafaciens sialidase (AUS) increased phagocytosis even further. Our results highlight the different mechanisms of increasing sialylation, which lead to the formation of the mature sperm sialome, as well as reveal the sialome's function in sperm survival within the female genital tract.

    Full Text Available Abstract Background Leprosy is a chronic infectious disease that has an impact on the Health-Related Quality of Life (HRQOL of sufferers as well as their children. To date, no study has investigated the effects of parental leprosy on the well-being of adolescent children. Methods A cross-sectional study was conducted in the Lalitpur and Kathmandu districts of Nepal. Adolescents with leprosy-affected parents (n = 102; aged 11–17 years and those with parents unaffected by leprosy (n = 115; 11–17 years were investigated. Self-reported data from adolescents were collected using the Kinder Lebensqualität Fragebogen (KINDLR questionnaire to assess HRQOL, the Center for Epidemiological Studies-Depression Scale (CES-D, and the Rosenberg Self-esteem Scale (RSES. Analysis of covariance (ANCOVA was used to compare scores between the two groups. Multiple regression analysis was conducted to explore the determinants of HRQOL for adolescents with leprosy-affected parents. Results ANCOVA revealed that the KINDLR and RSES scores were significantly lower among adolescents with leprosy-affected parents compared with unaffected parents. However, the scores of “Friends” and “School” subscales of KINDLR were similar between the two groups. The CES-D score was significantly higher among adolescents with leprosy-affected parents than for adolescents with unaffected parents. The KINDLR scores for adolescents with both parents affected (n = 41 were significantly lower than the scores for those with one parent affected (n = 61. Multiple regression analysis revealed that adolescents with leprosy-affected parents who had higher levels of depressive symptoms were more likely to have lower KINDLR scores. A similar result was seen for adolescents where both parents had leprosy. Conclusions Adolescents with leprosy-affected parents had higher levels of depressive symptoms, lower levels of self-esteem, and lower HRQOL compared with adolescents whose

    Different forms of anxiety-related behavior have been reported after a single drug use of many abused substances, however, less is known about how males and females are affected differently from exposure to various drugs. Furthermore, chronic prenatal methamphetamine (MA) exposure was shown to predispose the animal to an increased sensitivity to drugs administrated in adulthood. Using the Elevated plus-maze test (EPM), the first aim of the present study was to examine how male and female rats are affected by acute drug treatment with subcutaneously (s.c.) administrated (a) MA (1mg/kg); (b) drugs with a similar mechanism of action to MA: amphetamine (AMP, 1mg/kg), cocaine (COC, 5mg/kg), 3,4-methylenedioxymethamphetamine (MDMA, 5mg/kg); and (c) drugs with different mechanisms of action: morphine (MOR, 5mg/kg), and Δ 9-tetrahydrocannabinol (THC, 2mg/kg). The second aim was to determine if prenatally MA-exposed (5mg/kg) animals show an increased sensitivity to adult drug treatment. The parameters analyzed were divided into two categories: anxiety-related behavior and anxiety-unrelated/exploratory behavior. Our results showed in female rats a decreased percentage of the time spent in the closed arms (CA) after MA, and an increased percentage of the time spent in the open arms (OA) after MA, AMP, and COC treatment, indicating an anxiolytic-like effect. In females, MDMA and THC treatment increased the percentage of the time spent in the CA. An increased percentage of the time spent in the CA was also seen after MOR treatment in females as well as in males, indicating an anxiogenic-like effect. As far as the interaction between prenatal MA exposure and adult drug treatment is concerned, there was no effect found. In conclusion, it seems that: (a) in some cases female rats are more vulnerable to acute drug treatment, in terms of either anxiogenic- or anxiolytic-like effects; (b) prenatal MA exposure does not sensitize animals to the anxiety-related effects of any of the

    Knowledge of the mechanisms that regulate courtship and mating behavior in Psyttalia concolor (Szépligeti)-a koinobiont endophagous solitary parasitoid of the olive fruit fly,Bactrocera oleae (Rossi),and of other fruit flies-is essential to its mass rearing and management.Augmentative releases ofP.concolor for olive fruit fly control started in the Mediterranean areas in the 1950s and still continue with limited success.We determined the influence of visual and chemical cues on courtship and mating behavior of this braconid and the possible effect of the mating status of males and females in the perception of these cues.Our results suggest that integration of visual and chemical stimuli are fundamental for mate location and courtship.Indeed,the optimal response of the male was achieved when physical and chemical cues were simultaneously presented and vision and olfaction worked synergistically.

    Nearly 80% of adult smokers begin smoking during adolescence. Binge alcohol consumption is also common during adolescence. Past studies report that nicotine and ethanol activate dopamine neurons in the reward pathway and may increase synaptic levels of dopamine in the nucleus accumbens through nicotinic acetylcholine receptor (nAChR) stimulation. Activation of the reward pathway during adolescence through drug use may produce neural alterations affecting subsequent drug consumption. Consequently, the effect of nicotine exposure on binge alcohol consumption was examined along with an assessment of the neurobiological underpinnings that drive adolescent use of these drugs. Adolescent C57BL/6J mice (postnatal days 35-44) were exposed to either water or nicotine (200μg/ml) for ten days. On the final four days, ethanol intake was examined using the drinking-in-the-dark paradigm. Nicotine-exposed mice consumed significantly more ethanol and displayed higher blood ethanol concentrations than did control mice. Autoradiographic analysis of nAChR density revealed higher epibatidine binding in frontal cortical regions in mice exposed to nicotine and ethanol compared to mice exposed to ethanol only. These data show that nicotine exposure during adolescence increases subsequent binge ethanol consumption, and may affect the number of nAChRs in regions of the brain reward pathway, specifically the frontal cortex.

    Full Text Available This study aimed to assess cases of self-inflicted poisoning among adolescents reported by the Toxicological Care Center of a reference hospital in Recife-PE, Brazil. The data were collected between March and May 2010 from hospital charts and structured interviews with the participants and parents/guardians. Among the 25 cases of attempted suicide registered in the period, 21 were female adolescents, who made up the sample of the present study. The adolescents were between 13 and 19 years of age. Pesticides were the most frequent toxic agent used (61.9%. The results of the present study underscore the importance of studying suicide in this population, with a focus on family relations, in order to lay the foundation for the development of prevention and treatment programs for this vulnerable group.

    Children and adolescents with Autism Spectrum Disorder (ASD) are characterized by an impaired Theory of Mind (ToM). Recent evidence suggested that two aspects of ToM (cognitive ToM versus affective ToM) are differentially impaired in individuals with ASD. In this study, we examined the neural correlates of cognitive and affective ToM in children and adolescents with ASD compared to typically developing children (TDCs). Twelve children and adolescents with ASD and 12 age, IQ matched TDCs participated in this functional MRI study. The ToM task involved the attribution of cognitive and affective mental states to a cartoon character based on verbal and eye-gaze cues. In cognitive ToM tasks, ASD participants recruited the medial prefrontal cortex (mPFC), anterior cingulate cortex (ACC), and superior temporal gyrus (STG) to a greater extent than did TDCs. In affective ToM tasks, both ASD and TDC participants showed more activation in the insula and other subcortical regions than in cognitive ToM tasks. Correlational analysis revealed that greater activation of the mPFC/ACC regions was associated with less symptom severity in ASD patients. In sum, our study suggests that the recruitment of additional prefrontal resources can compensate for the successful behavioral performance in the ToM task in ASD participants. PMID:27084690

    blunted the hormonal response. However, severe shocks were followed by a surge of plasma corticosterone levels in both male and female clomipramine-treated rats. These results demonstrate that duration and intensity of stressful stimuli may deeply affect the behavioral response of rats in forced swim test and influence clomipramine effect in this behavioral model depending on gender-based variables, probably of the hormonal type. Plasma corticosterone levels correlate with the behavioral response to clomipramine treatment suggesting that reactivity of hypothalamus-pituitary-adrenal axis to stress may be involved in the antidepressant effect of this drug.

    Mlenga, Francis Howard

    The purpose of the study was to determine factors affecting elementary female student teachers' choice of science as a major at college level in Zimbabwe. The study was conducted at one of the Primary School Teachers' Colleges in Zimbabwe. A sample of two hundred and thirty-eight female student teachers was used in the study. Of these one hundred and forty-two were non-science majors who had been randomly selected, forty-one were science majors and forty-five were math majors. Both science and math majors were a convenient sample because the total enrollment of the two groups was small. All the subjects completed a survey questionnaire that had sixty-eight items. Ten students from the non-science majors were selected for individual interviews and the same was done for the science majors. A further eighteen were selected from the non-science majors and divided into three groups of six each for focus group interviews. The same was done for the science majors. The interviews were audio taped and transcribed. Data from the survey questionnaires were analyzed using Binary Logistic Regression which predicted factors that affected students' choice of science as a major. The transcribed interview data were analyzed used using domain, taxonomic and componential analyses. Results of the study indicated that elementary female students' choice of science as a major at college level is affected by students' attitudes toward science, teacher behavior, out-of-school experiences, role models, gender stereotyping, parental influence, peer influence, in-school experiences, and societal expectations, namely cultural and social expectations.

    Adolescence has long been viewed as a time of rapid change in many domains including physical, cognitive, and social. Adolescents must adapt based on developing skills and needs and acclimate to growing environmental pressures. Deaf adolescents are often faced with the additional challenge of managing these adaptations in a hearing world, where communication and access to information, especially about their social world, are incomplete at best and nonexistent at worst. This article discusses the research on several factors that influence a deaf adolescent's adaptation, including quality of life, self-concept, and identity development. Gaps in our knowledge are pointed out with suggestions for future research programs that can facilitate optimal development in adolescents who are deaf. PMID:27186150

    Major depressive disorder (MDD) often begins during adolescence and is projected to become the leading cause of global disease burden by the year 2030. Yet, approximately 40 % of depressed adolescents fail to respond to standard antidepressant treatment with a selective serotonin reuptake inhibitor (SSRI). Converging evidence suggests that depression is related to brain mitochondrial dysfunction. Our previous studies of MDD in adult and adolescent females suggest that augmentation of SSRI pharmacotherapy with creatine monohydrate (CM) may improve MDD outcomes. Neuroimaging with phosphorus-31 magnetic resonance spectroscopy (31P-MRS) can measure the high-energy phosphorus metabolites in vivo that reflect mitochondrial function. These include phosphocreatine (PCr), a substrate for the creatine kinase reaction that produces adenosine triphosphate. As part of the National Institute of Mental Health’s experimental medicine initiative, we conducted a placebo-controlled doseranging study of adjunctive CM for adolescent females with SSRI-resistant MDD. Participants were randomized to receive placebo or CM 2, 4 or 10 g daily for 8 weeks. Pre- and post-treatment 31P-MRS scans were used to measure frontal lobe PCr, to assess CM’s target engagement with cerebral energy metabolism. Mean frontal lobe PCr increased by 4.6, 4.1 and 9.1 % in the 2, 4 and 10 g groups, respectively; in the placebo group, PCr fell by 0.7 %. There was no group difference in adverse events, weight gain or serum creatinine. Regression analysis of PCr and depression scores across the entire sample showed that frontal lobe PCr was inversely correlated with depression scores (p = 0.02). These results suggest that CM achieves target engagement with brain bioenergetics and that the target is correlated with a clinical signal. Further study of CM as a treatment for adolescent females with SSRI-resistant MDD is warranted. PMID:26907087

    Full Text Available The objective of this study was to analyze the relationship between depressive symptoms and eating disorders in female adolescents. The sample included 371 girls ranging from 12 to 16 years of age in Juiz de Fora, Minas Gerais State, Brazil. The study used the Eating Attitudes Test (EAT-26 and Major Depression Inventory (MDI to evaluate eating disorders and depressive symptoms, respectively. The linear regression model showed that 18% of the EAT-26 scores were influenced by MDI (F(1, 370 = 14.18; p = 0.001. Moreover, the findings indicated a statistically significant association between depressive symptoms and eating disorders (χ2 = 14.71; Wald = 12.90; p = 0.001. The authors concluded that depressive symptoms were related to eating disorders in female adolescents. Thus, girls with some level of depression showed a greater tendency to adopt disordered eating as a daily habit.

    Body dissatisfaction is particularly prevalent during adolescence and has recently been linked to stress in females and males. However, prospective studies are needed to better understand the relationship between stress and body dissatisfaction. The present study investigates the direction of this association and the mediating role of self-esteem and body image importance. A sample of 298 adolescent females and males in Grades 7 to 10 (ages 12 to 17 years) were surveyed at two time points over a one-year period. Hierarchical regression analyses revealed that stress significantly predicted body dissatisfaction one year later. Furthermore, a multiple mediation analysis controlling for gender revealed a significant indirect effect in both cross-sectional and longitudinal models, indicating that stress predicts reductions in self-esteem and increases in body importance, which in turn predict body dissatisfaction. These findings suggest that stress, self-esteem, and body importance should be included in programmes aimed at improving body dissatisfaction. PMID:23993480

    Objective to assess Female Sexual Function Index (FSFI) scores and delay to resume sexual activity associated with a previous severe maternal morbidity. Method This was a multidimensional retrospective cohort study. Women who gave birth at a Brazilian tertiary maternity between 2008 and 2012 were included, with data extraction from the hospital information system. Those with potentially life-threatening conditions and maternal near miss episodes (severe maternal morbidity) were considered the exposed group. The control group was a random sample of women who had had uncomplicated pregnancy. Female sexual function was evaluated through FSFI questionnaire, and general and reproductive aspects were addressed through specific questions. Statistical analyses were performed using Mann-Whitney and Pearson´s Chi-square for bivariate analyses. Logistic regression was used to identify variables independently associated with lower FSFI scores. Results 638 women were included (315 at exposed and 323 at not exposed groups). The majority of women were under 30 years-old in the control group and between 30 and 46 years-old in the exposed group (p = 0.003). Women who experienced severe maternal morbidity (SMM) had statistically significant differences regarding cesarean section (82.4% versus 47.1% among deliveries without complications, p<0.001), and some previous pathological conditions. FSFI mean scores were similar among groups ranging from 24.39 to 24.42. It took longer for exposed women to resume sexual activity after index pregnancy (mean 84 days after SMM and 65 days for control group, p = 0.01). Multiple analyses showed no significant association of FSFI below cut-off value with any predictor. Conclusion FSFI scores were not different in both groups. However, they were lower than expected. SMM delayed resumption of sexual activity after delivery, beyond postpartum period. However, the proportion of women in both groups having sex at 3 months after delivery was similar

    Alterations in social behavior are a hallmark of many neurodevelopmental disorders in humans. In rodents, social behavior is affected by prenatal insults. The outcomes are dependent on the timing of the insult as well as the sex and age of the animal tested. The limbic system is particularly important for social behavior, and a peak of neurogenesis within this system occurs on gestational day (G)15. Neurons appear particularly vulnerable to ethanol insult around the time they become post-mito...

    This study aimed to examine the alterations in physiological and biochemical markers, after 17 weeks of ballet training in high level ballet dancers. Twenty four female ballet dancers from 12 to 15 years old took part in the study. The study followed 17 weeks of ballet training and analyzed changes in body composition, the autonomic nervous system and biochemical variables before and after (post) training. The internal training load was obtained using the session rating of perceived exertion (session-RPE) method, calculated as the mean weekly session-RPE, monotony and strain. After 17 weeks of training there were significant increases in body mass, height, lean body mass, total protein, urea, hemoglobin concentration, testosterone and thyroxine. During this period, decreases in relative body fat, uric acid, red blood cells, C-reactive protein, and ferritin were also found. After the training period, the autonomic modulation demonstrated significant positive alterations, such as increases in parasympathetic related indices. Based on the results obtained we concluded that ballet training led to improvements in body composition and autonomic modulation. In general hematological and biochemical variables demonstrated that the training did not have adverse effects on the health state of the adolescents. PMID:26555850

Based on the results obtained we concluded that ballet training led to improvements in body composition and autonomic modulation. In general hematological and biochemical variables demonstrated that the training did not have adverse effects on the health state of the adolescents.

    Heightened psychosocial stress coupled with maladaptive coping may be associated with greater sexual risk engagement. This study examined the association between stress levels and coping strategy use as predictors of sexual risk behavior engagement over 24 months among African-American adolescent females (N = 701; M = 17.6 years) enrolled in an STI/HIV risk-reduction intervention program. Participants completed audio computer assisted self-interview (ACASI) measures of global stress, interpersonal stress, coping strategy use, and sexual behaviors prior to intervention participation. Follow-up ACASI assessments were conducted at 6, 12, 18, and 24 months post-intervention. Generalized estimated equation models examined associations between baseline stress levels and coping strategy use as predictors of condom use (past 90 days, last sex) and multiple partners during follow-up. Global stress and individual coping strategy usage were not associated with differences in condom use. Higher interpersonal stress was associated with lower proportion condom use (p = .018), inconsistent condom use (p = .011), and not using a condom at last sex (p = .002). There were no significant associations between stress levels, coping strategy use, and multiple partners. Future research should explore mechanisms that may underlie the association between elevated interpersonal stress and decreased condom use among this population.

    This study aimed to examine the alterations in physiological and biochemical markers, after 17 weeks of ballet training in high level ballet dancers. Twenty four female ballet dancers from 12 to 15 years old took part in the study. The study followed 17 weeks of ballet training and analyzed changes in body composition, the autonomic nervous system and biochemical variables before and after (post) training. The internal training load was obtained using the session rating of perceived exertion (session-RPE) method, calculated as the mean weekly session-RPE, monotony and strain. After 17 weeks of training there were significant increases in body mass, height, lean body mass, total protein, urea, hemoglobin concentration, testosterone and thyroxine. During this period, decreases in relative body fat, uric acid, red blood cells, C-reactive protein, and ferritin were also found. After the training period, the autonomic modulation demonstrated significant positive alterations, such as increases in parasympathetic related indices. Based on the results obtained we concluded that ballet training led to improvements in body composition and autonomic modulation. In general hematological and biochemical variables demonstrated that the training did not have adverse effects on the health state of the adolescents. PMID:26555850

    It is well established that the parental phenotype can influence offspring phenotypic expression, independent of the effects of the offspring's own genotype. Nonetheless, the evolutionary implications of such parental effects remain unclear, partly because previous studies have generally overlooked the potential for interactions between parental sources of non-genetic variance to influence patterns of offspring phenotypic expression. We tested for such interactions, subjecting male and female Drosophila melanogaster of two different age classes to an immune activation challenge or a control treatment. Flies were then crossed in all age and immune status combinations, and the reproductive success of their immune- and control-treated daughters measured. We found that daughters produced by two younger parents exhibited reduced reproductive success relative to those of other parental age combinations. Furthermore, immune-challenged daughters exhibited higher reproductive success when produced by immune-challenged relative to control-treated mothers, a pattern consistent with transgenerational immune priming. Finally, a complex interplay between paternal age and parental immune statuses influenced daughter's reproductive success. These findings demonstrate the dynamic nature of age- and immune-mediated parental effects, traceable to both parents, and regulated by interactions between parents and between parents and offspring.

    Full Text Available We proposed that first year medical students who voluntarily participated in the Healthy Sexuality adolescent program would perform better than their peers on an adolescent counseling station at the year-end OSCE (Objective Structured Clinical Examination. In addition we compared medical students’ communication skills at the time of the program as assessed by self, peers and participating adolescents. Methods: Nineteen first year medical students voluntarily participated in the ongoing Healthy Sexuality program. Adolescent participants, medical student peer participants and medical students assessed communication components on a 7-point Likert scale at the end of the program. At the year-end OSCE, all first year medical students at the University of Western Ontario were assessed at an adolescent counseling station by a standardized patient (SP and a physician examiner. Statistical analysis examined differences between the two groups. Results: Students who participated in the Healthy Sexuality program did not perform better than their colleagues on the year-end OSCE. A statistically significant correlation between physician examiner and SP evaluations was found (r = 0.62. Adolescent participants communication skills assessments in the Healthy Sexuality Program demonstrated no significant correlation with medical student assessments (self or peer. Conclusions:Voluntary intervention with adolescents did not result in improved communication skills at the structured year-end examination. Further investigation will be directed towards delineating differences between SP and physician examiner assessments.

    In assessing the mental health of HIV/AIDS-affected children and adolescents in Sub-Saharan Africa, researchers often employ mental health measures developed in other settings. However, measures derived from standard Western psychiatric criteria are frequently based on conceptual models of illness or terminology that may or may not be an appropriate for diverse populations. Understanding local perceptions of mental health problems can aid in the selection or creation of appropriate measures. ...

  3. Adolescent Heavy Drinking Does Not Affect Maturation of Basic Executive Functioning: Longitudinal Findings from the TRAILS Study.

    Sarai R Boelema

    Full Text Available Excessive alcohol use is assumed to affect maturation of cognitive functioning in adolescence. However, most existing studies that have tested this hypothesis are seriously flawed due to the use of selective groups and/or cross-sectional designs, which limits the ability to draw firm conclusions. This longitudinal study investigated whether patterns of alcohol use predicted differences in maturation of executive functioning in adolescence. Additionally, gender was tested as a possible moderator.We used data from the Tracking Adolescents' Individual Lives Survey (TRAILS, which comprises a cohort of 2,230 Dutch adolescents. Maturation of executive functioning was measured by assessing the standardized improvement on each of four basic executive functions (i.e., inhibition, working memory, and shift- and sustained attention between ages 11 and 19. Participants were assigned to one of six (heavy drinking groups (i.e., non-drinkers, light drinkers, infrequent heavy drinkers, increased heavy drinkers, decreased heavy drinkers, and chronic heavy drinkers. We conducted linear regression analyses, and adjusted for relevant confounders.The six drinking groups did not reveal significant differences in maturation between drinking groups. E.g., maturation executive functioning of chronic heavy drinkers in comparison to non-drinkers; inhibition: B = -0.14, 95% CI [-0.41 to 0.14], working memory: B = -0.03, 95% CI [-0.26 to 0.21], shift attention: B = 0.13, 95% CI [-0.17 to 0.41], sustained attention: B = 0.12, 95% CI [-0.60 to 0.36]. Furthermore, gender was not found to be a significant moderator.Four years of weekly heavy drinking (i.e., chronic heavy drinkers did not result in measurable impairments in four basic executive functions. Thus, regular heavy drinking in adolescence does not seem to affect these basic behavioural measures of executive functioning.

    Background: Since type-2 diabetes is the most common chronic disease among Iranian female adolescents, we applied theory of planned behavior to examine the effect of training to intention to preventative nutritional behaviors for type-2 diabetes among female adolescents. Methods: In this experimental study 200 (11-14 year old) girls from 8 schools of Tehran city (100 in each intervention and control group) were recruited based on cluster sampling method during two stages. For intervention group, an educational program was designed based on the theory of planned behavior and presented in 6 workshop sessions to prevent type-2 diabetes. The data were collected before and two months after the workshops using a valid and reliable (α=0.72 and r=0.80) authormade questionnaire based on Ajzens TPB questionnaire manual. The data were analyzed using t-test, chi-square test and analysis of covariance. Results: Findings indicate that the two groups were homogeneous regarding the demographic characteristics before education, but the mean score of the theory components (attitudes, subjective norms, perceived behavioral control, and intention) was higher in the control group. Also, results showed all of the theory components significantly increased after the education in the intervention group (p=0.000). Conclusion: Training based on the theory of planned behavior enhances the intention to adherence preventative nutritional behaviors for type-2 diabetes among the studied female adolescents.

    Full Text Available Background: Interpersonal violence (IPV is associated with higher risk of depression. Female Chinese rural-to-urban migrants may experience greater depression following exposure to IPV due to lack of social support and integration within their receiving communities. The current study estimated the prevalence of IPV among rural-to-urban migrants in Guangzhou, China, and evaluated the moderating effects of social resources on migrant's depression symptoms. Method: We recruited 1,368 women (1,003 migrants and 365 local-born of childbearing age from population and family planning centers in two districts using a quota sampling method matched to the 2012 population census. Chinese versions of the Conflict Tactics Scale 2 Short Form, Center for Epidemiological Studies Depression Scale and the Social Support Rating Scale measured IPV, depression, and social support. Social integration was measured with a locally derived scale. Results: Migrants reported a similar prevalence for IPV (41.20% to local women (39.20%. Bivariate comparisons demonstrated that migrants reported greater depression (11.8±8.9 vs. 10.0±8.8, t=−3.27, p<0.001 and less social support (22.2±5.1 vs. 27.1±5.5, t=14.84, p<0.001. Regression analysis indicated that the effect of violence on depression symptoms for migrant women was moderated by social integration. Women who experienced violence and had greater integration in their community reported less depression than women who experienced violence but reported less social integration. Conclusion: A high prevalence of IPV was reported in our sample. Social integration is a key risk factor for migrant mental health. Social services aimed to reduce IPV and integrate migrants in their new communities are needed.

    Papillon-Lefevre Syndrome (PLS) is a rare inherited autosomal-recessive condition with one-third of the patients' showing consanguinity of the parents. Lesions are characterised by palmar-plantar hyperkeratosis and hyperhidrosis. Early onset of periodonditis, severe periodontal destruction in both primary and permanent dentitions, and calcification of the duramater form the three important features of this disease. Here, we present a case of a 14-year-old female who presented to the Department of Oral Medicine and Radiology with a complaint of mobility of the teeth since four months. Oral examination of the patient showed generalised mobility of the teeth. General physical examination of the patient showed dry scaly skin on dorsum of bilateral feet, hands, and knee. The patient had familial history positive for consanguinity. The patient was medically diagnosed as positive for PLS. The patients with PLS show combination of dermatological and dental lesions and it requires the dentist to assume a more prominent role in early treatment and rehabilitation. There is a need for symbiotic and synergetic approach between the two specialties for effective management of this rare disease.

    The influence of amount and type of dietary fat on circulating concentrations of prolactin and estradiol-17 beta in female F344 rats from which blood was sampled by decapitation under ether anesthesia was compared with that in rats from which blood was collected without anesthesia. The animals were fed isonutrient (adjusted for differences in energy density) semipurified diets containing 5% or 20% (by weight) sunflower seed oil or lard. Blood was sampled by decapitation with or without standardized ether anesthesia during the afternoon of proestrus-estrus or the morning of metestrus-diestrus, as determined by examination of vaginal smears. Plasma hormone concentrations were measured by radioimmunoassay. Prolactin levels were lower during proestrus-estrus in rats fed a low-fat diet than in animals fed a high-fat diet, statistically independent of the type of dietary fat, but only when blood was sampled by decapitation under ether anesthesia [p = 0.0384, 2-way analysis of variance (ANOVA)]. No such difference was found in rats decapitated without anesthesia. This effect of amount of dietary fat on prolactin in proestrus-estrus animals anesthetized with ether was predominantly present in animals fed polyunsaturated fat (p rats fed saturated fat diets. During metestrus-diestrus, prolactin levels were significantly lower in animals fed a high-saturated fat diet than in those fed low-saturated fat, low-unsaturated fat, or high-unsaturated fat diets, independent of the blood sampling conditions (p conversion efficiency was lower in animals fed low-fat diets than in those fed high-fat diets. This study confirms the hypothesis that effects of dietary fat, particularly polyunsaturated fat, on circulating prolactin occur only during (ether) stress. Because stress is a frequent and normal phenomenon, this observation implies that the mammary glands of animals with a high dietary intake of polyunsaturated fat are frequently exposed to higher circulating prolactin concentrations

    Full Text Available Background: Although sexual issues are openly discussed in the media, sexuality and reproductive functions are treated as taboo. Menstruation is a normal physiologic process, but carries various meanings within cultures and is rarely discussed amongst families and communities.Purpose: This study sought to assess the knowledge and practices of secondary school girls towards menstruation in the Thulamela municipality of Limpopo Province, South Africa.Methods: A quantitative descriptive study design was used and respondents were selected by means of convenience sampling from a population of secondary school girls. The sample consisted of 273 secondary school girls doing Grades 10–12. A self-administered questionnaire was used to collect data, which was analysed by computing frequencies and percentages using the Statistical Package for Social Sciences (SPSS version 12.Findings: The findings revealed that respondents experienced menarche at 13 years and that menstruation is a monthly bleeding (80% that happens to every female; it is a sign of adulthood (91%. 15% reported that it is the removal of dirt from the stomach and abdomen, 67% indicated the source of menstruation being the uterus, 65% the vagina and 13% from the abdomen. 73% reported having fear and anxiety at the first experience of bleeding and that they could not maintain adequate hygienic practices due to a lack of privacy and sanitarytowels.Conclusion: Interventions are needed to increase girls’ opportunities to discuss menstruation and access information from adults including mothers, parents and guardians. School-based sexuality education should be comprehensive, begin early and be regularly repeated.

    The human stress response evolved to maximize an individual's probability of survival when threatened. The present study addressed whether physical danger modulates perception of an unrelated ambiguous threat and, if so, to what extent this response is sex- specific. The authors utilized a first-time tandem skydive as a stressor, which had been previously validated as producing a highly-controlled, genuinely stressful environment. In a counter-balanced within-subjects design, participants wore a virtual reality helmet to complete an emotion-identification task during the plane's ascent (stress condition) and in the laboratory (control condition). Participants were presented static male faces morphed between 20-80% aggression, which gradually emerged from degraded images. Using a binary forced-choice design, participants identified each ambiguous face as aggressive or neutral. Results showed that participants characterized emotion more rapidly under stress versus control conditions. Unexpectedly, the results also show that while women were more sensitive to affect ambiguity than men under control conditions, they exhibited a marked decrease in sensitivity equivalent to men while under stress.

    Experiences during critical periods, such as the neonatal and adolescence, play a critical role in determining adult stress-coping behavior. Based on the aforementioned we developed an experimental protocol, which included a neonatal experience and a social stress during adolescence. The serotonergic system is known as an important modulator of coping ability and, in general, emotional balance in both normal and pathological states, such as depression and anxiety, for which females are more vulnerable. Thus in the present work we used female rats and determined 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), and 5-hydroxytryptamine receptor type 1A (5-HT(1A)) receptor levels in the prefrontal cortex (PFC) and the amygdala (AMY). During postnatal days 10-13 (PND 10-13) rat pups were exposed to a T-maze, one arm of which lead to the mother. One group of animals was allowed contact with the mother (rewarded-receiving expected reward (RER)), whereas the other was denied the expected reward (DER). High performance liquid chromatography (HPLC) analysis revealed that in both the PFC and in AMY, adult RER animals had higher basal 5-HT levels. Furthermore, in the AMY of this group of animals, higher levels of 5-HT(1A) receptors were detected by Western blot analysis. In adulthood rats were exposed to the Forced Swimming Test/Stress (FST/S). RER animals not exposed to the adolescent stress exhibited longer immobility time during both the first and second day of FST. Corticosterone levels following the FST fell faster in the DER animals. Adolescent stress affected the responses to the adult FSS only in the DER animals, which had decreased 5-HT in the AMY and increased immobility time on both days of the FST, compared with the DER, not stressed in adolescence. The phenotype of the DER animals is in line with the "match-mismatch" hypothesis, which states that if two events during critical periods of life "match" in being mildly stressful, their interaction can be adaptive.

    Objective This study investigated the association of cervical Human Papillomavirus (HPV) infection with cumulative psychosocial risk reflecting family disadvantage, psychological distress, and unhealthy life style. Methods The sample (N=745) was comprised of sexually-active female adolescent patients (12-19 years), primarily ethnic minorities, enrolled in a free HPV vaccination program. Subjects completed questionnaires and provided cervical swabs for HPV DNA testing. Unweighted and weighted Principal Component Analyses (PCA) for categorical data were used to derive multi-systemic psychosocial risk indices using nine indicators: low socioeconomic status, lack of adult involvement, not attending high-school/college, history of treatment for depression/anxiety, antisocial/delinquent behavior, number of recent sexual partners, use of alcohol, use of drugs, and dependency risk for alcohol/drugs. The association between cervical HPV (any-type, high risk-types, vaccine-types) assayed by polymerase chain reaction and self-reported number of psychosocial risk indicators was estimated using multivariable logistic regression. Results Subjects had a median of three psychosocial risk indicators. Multiple logistic regression analyses showed associations with unweighted and weighted number of psychosocial indicators for HPV any-type (adjusted odds ratio [aOR]=1.1; 95% confidence interval [CI]: 1.0-1.2 ); with the strongest associations between weighted drug/alcohol use, drug/alcohol dependency risk, and antisocial/delinquent behavior and detection of HPV vaccine-types (aOR=1.5; 95%CI: 1.1-2.0) independent of number of recent sexual partners and vaccine dose (0-3). Conclusion Increased HPV infections including HPV vaccine-types were associated with greater number of psychosocial risk indicators even after controlling for demographics, sexual behavior, history of chlamydia, and vaccine dose.

    Little is known about the psychosocial functioning of persons who have recovered from dysthymic disorder. Such information might be useful in identifying trait markers for dysthymia, and for guiding continuation and maintenance treatment. We explored this issue using data from the Oregon Adolescent Depression Project, a large community-based study of the epidemiology of psychiatric disorders in a high school population. Four groups of adolescents were identified: 38 with a past history of dysthymic disorder; 217 with a past history of major depressive disorder; 142 with a past history of non-affective disorders; and 1079 with no lifetime history of psychopathology. The groups were compared on an extensive battery of psychosocial variables. The most consistent and diagnostically specific finding was that adolescents with a past history of dysthymic disorder reported having a significantly lower level of social support from friends than each of the other three groups of adolescents. Adolescents with a past history of dysthymic disorder also reported significantly higher levels of depressive, internalizing and externalizing symptoms and daily hassles than adolescents with no lifetime history of psychopathology. In addition, they reported higher levels of depressive symptoms and self-consciousness, but fewer externalizing symptoms than adolescents with a past history of non-affective disorders. These data suggest that adolescents with dysthymic disorder continue to experience significant difficulties in psychosocial functioning even after recovery.

    Full Text Available Introduction & Objective: Sedentary women are at risk for problems such as obesity, diabetes, depression and cardiovascular disease. Meanwhile, due to long working hours and excessive travel time from home to work and vice versa the employees have minimal physical activity .The purpose of this study was to investigate the effective psychometric factors on physical activity of female employees, according to the Trans-theoretical Model and theory of planned behavior. Materials & Methods: In this cross-sectional study, 95 female staff of Tehran University was selected through a call. In order to collect data, a questionnaire with acceptable, reliability and validity, including demographic data, and constructs of planned behavior theory as well as Trans-theoretical Model was used. The data was analyzed using SPSS version 21 statisti-cal tests; correlation and stepwise regression were also performed. Results: In this study, 72% of the population was in the inactive stages (pre-contemplation, contemplation and preparation and only 28% of patients had regular physical activity. There was a significant positive correlation between the behavioral intention and attitude scores (P = 0.02, perceived behavioral control (P = 0.000, self-efficacy (P = 0.000 and stage of change (P = 0.000, but subjective norms score (P = 0.605 was irrelevant. Conclusion: The results of this study showed that self-efficacy and perceived behavioral con-trol can affect female employees’ intention and physical activity behaviors. So, the authori-ties should seriously consider these factors in educational planning for this stratum of society, remove barriers for the participation of more employees in sporting activities, and offer fa-cilitators at the community level.

METHODS AND RESULTS: Although we found no differences on NO production in females SAM prone (SAMP, aged compared to SAM resistant (SAMR, young, by either DAF-2 fluorescence or plasmatic nitrite/nitrate (NO2/NO3, in both cases, E2 treatment increased NO production in SAMR but had no effect in SAMP. Those results are in agreement with changes of eNOS protein and gene expression. E2 up-regulated eNOS expression in SAMR but not in SAMP. E2 is also known to increase NO by decreasing its catabolism by superoxide anion (O(2(-. Interestingly, E2 treatment decreased O(2(- production in young females, while increased O(2(- in aged ones. Furthermore, we observed that aging changed expression ratio of estrogen receptors (ERβ/ERα and levels of DNA methylation. Increased ratio ERβ/ERα in aged females is associated to a lack of estrogen modulation of NO production and with a reversal in its antioxidant effect to a pro-oxidant profile. CONCLUSIONS: Together, our data suggest that aging has detrimental effects on E2-mediated benefits on NO bioavailability, partially by affecting the ability of E2 to induce up regulation of eNOS and decrease of O(2(-. These modifications may be associated to aging-mediated modifications on global DNA methylation status, but not to a specific methylation at 5'flanking region of ERα gene.

    Children with a facial difference are presumed to be at risk of social stigmatization. The purposes of this study were twofold: (1) to assess the effect of facial differences on social perceptions by unaffected children and adolescents; and (2) to identify perceiver characteristics that predict stereotypical attitudes toward facial differences. Participants were 344 non-affected children and adolescents, ages 8-17 years. Participants rated digitally altered images of 12 children depicted either with or without a facial difference. Results show that participants attributed less favorable characteristics to children with a facial difference than to those without. Moreover, participants reported less willingness to interact with or befriend a child with a facial difference. Significant predictors of low discriminative attitudes were older participant age and previous contact with someone with a facial difference. Our data call attention to the need for public education programs targeted at reducing negative attitudes toward facial differences.

    The relationship between negative affectivity (NA) and emotion regulation (ER) in determining anxiety and depressive symptomatology was examined in a large (n=1441) sample of adolescents (12-17 years old). Two models, diverging only as to inclusion or exclusion of a path from NA to negative ER, were analyzed through structural equation modeling; the goal was to explore the mediational or non-mediational role of ER in determining anxiety symptoms. The models yielded similar adequate fit to data, indicating that both NA and negative ER contribute to anxiety symptoms which, in turn, significantly determine depressive symptomatology. The mediational model better captures the relationships revealed in the data, with NA determining negative ER to a great extent. Additionally, most individuals scoring highly in NA also tend to score highly in negative ER, indicating that adolescents with heightened NA are prone to a dysfunctional style of ER.

    Full Text Available This study investigates the relationship between three different cognitive processes underlying the Iowa Gambling Task (IGT and adolescent smoking behaviors in a longitudinal study. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu City, China. The participants were followed from 10th grade to 11th grade. When they were in the 10th grade (Time 1, we tested these adolescents’ decision-making using the Iowa Gambling Task and working memory capacity using the Self-ordered Pointing Test (SOPT. Self-report questionnaires were used to assess school academic performance and smoking behaviors. The same questionnaires were completed again at the one-year follow-up (Time 2. The Expectancy-Valence (EV Model was applied to distill the IGT performance into three different underlying psychological components: (i a motivational component which indicates the subjective weight the adolescents assign to gains versus losses; (ii a learning-rate component which indicates the sensitivity to recent outcomes versus past experiences; and (iii a response component which indicates how consistent the adolescents are between learning and responding. The subjective weight to gains vs. losses at Time 1 significantly predicted current smokers and current smoking levels at Time 2, controlling for demographic variables and baseline smoking behaviors. Therefore, by decomposing the IGT into three different psychological components, we found that the motivational process of weight gain vs. losses may serve as a neuropsychological marker to predict adolescent smoking behaviors in a general youth population.
