Closeness in relationships as a mediator between sexual abuse in childhood or adolescence and psychopathological outcome in adulthood.

The risk of adverse psychological outcomes in adult victims of childhood and adolescent sexual abuse (CSA) has been documented; however, research on possible mediating variables is still required, namely with a clinical perspective. The attachment literature suggests that secure interpersonal relationships may represent such a variable. Twenty-eight women who had experienced episodes of CSA, and 16 control women, were interviewed using Bremner's Early Trauma Inventory and the DSM-IV Global Assessment of Functioning; they also responded to Collins' Relationship Scales Questionnaire, evaluating adult attachment representations in terms of Closeness, Dependence and Anxiety. Subjects with an experience of severe abuse reported significantly more interpersonal distance in relationships (low index of Closeness) than other subjects. The index of psychopathological functioning was correlated with both the severity of abuse and attachment (low index of Closeness). Regression analysis on the sample of abused women revealed that attachment predicted psychopathology when abuse was controlled for, whereas abuse did not predict psychopathology when attachment was controlled for. Therefore, preserving a capacity for closeness with attachment figures in adulthood appears to mediate the consequences of CSA on subsequent psychopathological outcome.

Oxytocin response to an experimental psychosocial challenge in adults exposed to traumatic experiences during childhood or adolescence.

Long-term implications of the exposure to traumatizing experiences during childhood or adolescence, such as sexual abuse, or cancer, have been documented, namely the subjects' response to an acute stress in adulthood. Several indicators of the stress response have been considered (e.g. cortisol, heart rate). Oxytocin (OT) response to an acute stress of individuals exposed to trauma has not been documented. Eighty subjects (n=26 women who had experienced episodes of child abuse, n=25 men and women healthy survivors of cancer in childhood or adolescence, and 29 controls) have been submitted to a laboratory session involving an experimental stress challenge, the Trier social stress test. Overall, there was a clear OT response to the psychosocial challenge. Subjects having experienced a childhood/adolescence life-threatening illness had higher mean levels of OT than both abused and control subjects. There was a moderate negative relationship between OT and salivary cortisol. It is suggested that an acute stress stimulates OT secretion, and that the exposure to enduring life-threatening experiences in childhood/adolescence has long-lasting consequences regarding the stress system and connected functions, namely the activation of OT secretion. Better knowledge of such long-term implications is important so that to prevent dysregulations of the stress responses, which have been shown to be associated to the individual's mental health.

Changing the future: experiencing adolescence in contemporary Ireland: sexual health and behaviour.

If we create the space in which children and young people can talk openly and in their own language even upon challenging subjects such as sex, then we are likely to learn more from what they tell usâ?T proposes the final UNICEF Ireland report which examines adolescent perspectives on sexual health and behaviour. Key findings in the report included: 63%, and 1 in 5 sixteen year old respondents, reported that they have had sex; 1 in 5 sexually active respondents reported that they did not use a condom the first time that they had sex; 2 in 5 girls who were sexually active reported that they had consumed alcohol before their first sexual experience, compared to 3 in 10 boys; The majority of respondents (54%) reported that they had watched pornography on the internet, and more than one third of the respondents who had watched pornography on the internet believed that it was accurate or educational; Only 1 in 5 respondents reported that they ever speak to their parents about sex. Noting â?~the broad spectrum from which young people living in Ireland draw down information about sexâ?T the UNICEF Ireland report concludes that â?~we must be sure that when a young person is making decisions about their sexual health and behaviour, every opportunity is afforded them in terms of open discussion, understanding, support, information and adviceâ?T Commenting on the Report, Amel Yucef a Youth Health Coordinator at the Base Youth Centre, Ballyfermot said â?oAs the participants in UNICEF Irelandâ?Ts survey have shown, many young people do not feel equipped with the information and support they need to make informed choices about their sexual health. Providing those supports is a priority for us at the Base.â? The Youth Health Programme, that Amel co-ordinates is a HSE funded initiative which was created to respond to the health needs of young people, as identified by the young people of the Dublin 10 area themselves. The Programme delivers community-based and youth-friendly health responses, based upon a harm-reduction model. The Youth Health Programme works towards building the capacity of young people to access health services, while also encouraging those services to deliver in an accessible and youth-friendly way.This resource was contributed by The National Documentation Centre on Drug Use.

The influence of attachment on perceived stress and cortisol response to acute stress in women sexually abused in childhood or adolescence.

The long-term implications of sexual abuse in childhood or adolescence (CSA) have been relatively well documented regarding attachment (disorganized attachment in childhood, unresolved trauma in adulthood), stress reactions (altered patterns of stress reactivity under experimental conditions), and psychopathology. Attachment has been shown to mediate the implications of CSA, namely on psychopathology. The implication of attachment on stress responses of abused persons has not been documented. Twenty-seven 20-46 years old women who had experienced episodes of CSA, and 17 controls have been interviewed using the Adult Attachment Interview. Sixty-three percent of abused women presented an unresolved trauma (12% for the controls). Thirty-six women (14 controls and 22 abused) came again to the laboratory for a session involving an experimental stress challenge (TSST). Subjects provided repeated appreciations of perceived stress on visual analogue scales and saliva samples were collected to assay cortisol levels. Whereas abused women with unresolved trauma showed the highest levels of perceived stress, they simultaneously presented the most suppressed cortisol reactions (there were significant post hoc differences between "unresolved abused" and controls on the increase of perceived stress and on cortisol recovery after the acute stress). It is suggested that important stressful experiences (such as CSA), especially when they have not been psychologically assimilated, may cause a disconnection, during subsequent mildly stressful circumstances, between the perception of stress and natural defensive body reactions.

Education and male-female differences in later-life cognition: international evidence from latin america and the Caribbean.

This study explores the role of early-life education for differences in cognitive functioning between men and women aged 60 and older from seven major urban areas in Latin America and the Caribbean. After documenting statistically significant differences in cognitive functioning between men and women for six of the seven study sites, I assess the extent to which these differences can be explained by prevailing male-female differences in education. I decompose predicted male-female differences in cognitive functioning based on various statistical models for later-life cognition and find robust evidence that male-female differences in education are a major driving force behind cognitive functioning differences between older men and women. This study therefore suggests that early-life differences in educational attainment between boys and girls during childhood have a lasting impact on gender inequity in cognitive functioning at older ages. Increases in educational attainment and the closing of the gender gap in education in many countries in Latin America and the Caribbean may thus result in both higher levels and a more gender-equitable distribution of later-life cognition among the future elderly in those countries.

Association between obesity indices and cardiovascular risk factors in late adolescence in the Seychelles.

ABSTRACT: BACKGROUND: The ability of different obesity indices to predict cardiovascular risk is still debated in youth and few data are available in sub Saharan Africa. We compared the associations between several indices of obesity and cardiovascular risk factors (CVRFs) in late adolescence in the Seychelles. METHODS: We measured body mass index (BMI), waist circumference, waist/hip ratio (WHiR), waist/height ratio (WHtR) and percent fat mass (by bioimpedance) and 6 CVRFs (blood pressure, LDL-cholesterol, HDL-cholesterol, triglycerides, fasting blood glucose and uric acid) in 423 youths aged 19-20 years from the general population. RESULTS: The prevalence of overweight/obesity and several CVRFs was high, with substantial sex differences. Except for glucose in males and LDL-cholesterol in females, all obesity indices were associated with CVRFs. BMI consistently predicted CVRFs at least as well as the other indices. Linear regression on BMI had standardized regression coefficients of 0.25-0.36 for most CVRFs (p<0.01) and ROC analysis had an AUC between 60%-75% for most CVRFs. BMI also predicted well various combinations of CVRFs: 36% of male and 16% of female lean subjects (BMI P90). CONCLUSION: There was an elevated prevalence of obesity and of several CVRFs in youths in Seychelles. BMI predicted single or combined CVRFs at least as well as other simple obesity indices.

Médecine de l'adolescence. La Guglera: une réponse nouvelle et originale aux adolescents gravement obèses et sans travail [Adolescent medicine in Guglera: a novel approach for unemployed, severely obese adolescents]

The Center "la Guglera", located in the canton of Fribourg (Switzerland) provides a novel approach to the care of severely obese adolescents who are currently unemployed. These young people, whose BMI is usually higher than 35 to 40 kg/m2 spend a 6 to 12 months long stay in an in-patient institution which also takes care of other unemployed non obese adolescents on an outpatient basis. Besides a nutritional education which is part of the everyday life of the institution, the program includes a generous amount of hours of physical activities and sports. The adolescents also participate in a rehabilitation training program which fosters the future integration in a professional milieu, such as an apprenticeship. The short term results of la Guglera seem very promising. The program is financially co-supported by the Swiss and cantonal administrations, the insurance companies and the parents.

Smoking and adolescence: Exploring tobacco consumption and related attitudes in three different age groups in Switzerland

The present study constitutes an investigation of tobacco consumption, related attitudes and individual differences in smoking or non-smoking behaviors in a sample of adolescents of different ages in the French-speaking part of Switzerland. We investigated three school-age groups (7th-grade, 9th-grade, and the second-year of high school) for differences in attitude and social and cognitive dimensions. We present both descriptive and inferential statistics. On an inferential level, we present a binary logistic regression-based model predicting risk of smoking. The resulting model most importantly suggests a strong relationship between smoking and alcohol consumption (both regular and sporadic). We interpret this result in terms of both the impact of the actual campaigns and the cognitive processes associated with adolescence.

Late morbidity during childhood and adolescence in previously premature neonates after patent ductus arteriosus closure.

The health status of previously premature neonates after closure of a patent ductus arteriosus (PDA) was analyzed in childhood and adolescence. Physician questionnaires were used to study 180 hospital survivors among 210 consecutive premature neonates who underwent PDA closure between 1985 and 2005. Complete follow-up data were obtained for 129 patients (72%). During a median follow-up period of 7 years (range, 2-22 years), three late deaths (2.3%) had occurred. Only 45% of the patients were considered healthy. Morbidity included developmental delay (41.1%), pulmonary illness (12.4%), neurologic impairment (14.7%), hearing impairment (3.9%), gastrointestinal disease (3.1%), and thoracic deformity (1.2%). None of the adverse variables during the neonatal period (intraventricular hemorrhage, bradycardia apnea syndrome, bronchopulmonary dysplasia, pulmonary bleeding, hyaline membrane disease, artificial respiration time [continuous positive airway pressure + intubation], or necrotizing enterocolitis) statistically predicted respective system morbidity at the follow-up evaluation. Hyaline membrane disease (odds ratio, 2.5; p = 0.026) and longer hospitalization time (odds ratio, 1.2 days per 10 hospitalization days; p = 0.032) in the newborn period were significant predictors of an unhealthy outcome at the last follow-up evaluation. Survival until childhood after closure of a hemodynamically significant PDA in premature neonates is satisfactory. However, physical and neurodevelopmental co-morbidity persist for half of the patients, perhaps as a sequela of prematurity unrelated to ductus closure.

Troubles du cycle à l'adolescence: une banalité [Menstrual disorders in adolescents: commonplace or worrisome?].

The first menstrual cycles following menarche are often caracterized by irregular and/or heavy bleeding. The adolescent patient may be worried by these episodes of bleeding. In 50-80% of cases these are anovulatory bleeding due to the immaturity of the gonadotrophic axis. Nevertheless pathologies such as von Willebrand disease, genital infection, polycystic ovary syndrom, eating disorders, a tumor or a pregnancy may be diagnosed by bleeding abnormalities. The challenge for the physician is to distinguish between bleeding abnormalities secondary to anovulation and pathologies where investigations and specific follow-up is mandatory. Adolescents who experience abnormal bleeding must be counceled according to their perceptions and expectations.

Improved statistical evaluation of group differences in connectomes by screening-filtering strategy with application to study maturation of brain connections between childhood and adolescence.

Detecting local differences between groups of connectomes is a great challenge in neuroimaging, because the large number of tests that have to be performed and the impact on multiplicity correction. Any available information should be exploited to increase the power of detecting true between-group effects. We present an adaptive strategy that exploits the data structure and the prior information concerning positive dependence between nodes and connections, without relying on strong assumptions. As a first step, we decompose the brain network, i.e., the connectome, into subnetworks and we apply a screening at the subnetwork level. The subnetworks are defined either according to prior knowledge or by applying a data driven algorithm. Given the results of the screening step, a filtering is performed to seek real differences at the node/connection level. The proposed strategy could be used to strongly control either the family-wise error rate or the false discovery rate. We show by means of different simulations the benefit of the proposed strategy, and we present a real application of comparing connectomes of preschool children and adolescents.

Personality traits, cognition and volumetric MRI changes in elderly patients with early-onset depression: A 2-year follow-up study.

Previous studies revealed personality changes in elderly patients with early-onset depression (EOD) that persist in euthymic stages. However, depression in older patients is a complex disorder that may affect not only personality, but also cognition and brain structure. To address this issue, a cross-sectional comparison and 2-year follow-up of 28 EOD elderly patients and 48 healthy controls included detailed neurocognitive assessment, estimates of brain volumes in limbic areas and white matter hyperintensities, as well as evaluation of the Five Factor Model of personality, in a remitted mood state. Results revealed that cognitive performances as well as brain volumes were preserved in EOD patients both at baseline and at follow-up. The increased Neuroticism factor and Anxiety facet scores as well as the decreased Warmth and Positive Emotions facet scores found at baseline reached the level of healthy controls after 2years. Only the Depression facet scores remained significantly higher in EOD patients compared to controls upon follow-up. Results were independent of depressive relapse since baseline (25% of patients). These findings suggest that both cognitive performances and brain volumes show long-term preservation in older EOD patients. In contrast, the depression-related personality facet might be a trait like marker that persists in the long-term evolution of this disorder.
