BACKGROUND: HIV-infected (HIV-pos) male children/youth showed lower bone mineral density at sexual maturity than HIV-uninfected (HIV-neg) females. It is not known whether complications of HIV disease, including abnormal body fat distribution, contribute to lower bone accrual in male HIV-pos adolescents. METHODS: In a cross-sectional study, we evaluated the relationship between body composition (fat and lean mass) and bone mass in HIV-pos and HIV-neg children/youth and determined if it is modified by HIV status and sex...

INTRODUCTION: Sexual violence against children is a hidden problem. Medical examination and evaluation is needed to search for possible injuries, exclude infections, procure legal evidence and ensure the child´s welfare. We assessed medical evaluations done at Landspitali University Hospital and in the Reykjavik Children's House, a specialized clinic for childhood abuse cases. MATERIAL AND METHODS: Retrospective descriptive analysis was performed on the standardized medical examinations...

There are limited data on the prevalence of risky sexual behaviours in individuals failing first-line antiretroviral therapy (ART) and changes in sexual behaviour after switch to second-line ART. We undertook a sexual behaviour sub-study of Ugandan adults enrolled in the Europe-Africa Research Network for the Evaluation of Second-line Therapy trial. A standardized questionnaire was used to collect sexual behaviour data and, in particular, risky sexual behaviours (defined as additional sexual partners to main sexual partner, inconsistent use of condoms, non-disclosure to sexual partners, and exchange of money for sex)...

This study explored sexual satisfaction in older heterosexual Australians using data from a national sample of 1,583 men and women aged 60+ who hoped or planned to have sex in the future. Data collection took place in 2015; participants were recruited using a variety of online and offline advertisements. Less than half the sample (46%) reported they were very or extremely satisfied with their sexual lives. Those who had sex more often and were more interested in sex were more likely to be satisfied, while those who wanted sex more often in the future were less likely to be satisfied, as were men who had experienced sexual difficulties...

Recent developments in cancer diagnostics and treatments have considerably improved long-term survival rates. Despite improvements in chemotherapy regimens, more focused radiotherapy and diverse surgical options, cancer treatments often have gonadotoxic side-effects that can manifest as loss of fertility or sexual dysfunction, particularly in young cancer survivors. In this review, we focus on two pertinent quality-of-life issues in female cancer survivors of reproductive age-fertility preservation and sexual function...

Age at maturity is a key life-history trait of most organisms. In anadromous salmonid fishes such as Atlantic Salmon (Salmo salar), age at sexual maturity is associated with sea age, the number of years spent at sea before the spawning migration. For the first time, we investigated the presence of two nonsynonymous vgll3 polymorphisms in North American Atlantic Salmon populations that relate to sea age in European salmon and quantified the natural variation at these and two additional candidate SNPs from two other genes...

STUDY OBJECTIVE: Most women begin sexual activity as teenagers but nearly 20% of women in France younger than 25 years rely on less effective contraceptive methods (condoms or methods such as withdrawal or periodic abstinence). We sought to analyze the association with less effective contraception among women aged 15-24 years in France and communication about sex and contraception with their parents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS AND MAIN OUTCOME MEASURES: The analyses focused on 713 sexually active women who did not currently want a child, were using contraception, and were interviewed in 2010 in a national cross-sectional probability survey (FECOND) when they were 15-24 years old...

BACKGROUND: Pediatricians play a crucial role in the identification and management of child abuse and neglect (CAN) but they often don't have a formal specialized training. METHODS: We analysed retrospectively data about patients, 0 - 18 years of age, victims of CAN between 1 April 2005 and 30 April 2015. The aim of the study was to evaluate the effect of a multidisciplinary educational program, "CAN: prevention strategies, individuation and treatment", on the knowledge, case recognition, treatment and follow-up of physicians of Gemelli University Hospital in Rome, regarding physical, sexual abuse and neglect...

Phenotypic differences between males and females are ubiquitous throughout the animal kingdom. Therefore, investigating the extent to which sex-dependent genetic effects contribute to phenotypic variation is important in understanding the evolutionary response of each sex to natural and artificial selection. Sex-specific differences in growth patterns and age at sexual maturity have been observed in a number of anadromous salmonid fishes. In these species, faster growing individuals in a given cohort often mature earlier than conspecifics, and earlier maturing individuals are often males...

Impulse control disorders (ICDs), such as compulsive gambling, buying, sexual, and eating behaviors, are a serious and increasingly recognized complication in Parkinson's disease (PD), occurring in up to 20% of PD patients over the course of their illness. Related behaviors include punding (stereotyped, repetitive, purposeless behaviors), dopamine dysregulation syndrome (DDS) (compulsive medication overuse), and hobbyism (e.g., compulsive internet use, artistic endeavors, and writing). These disorders have a significant impact on quality of life and function, strain interpersonal relationships, and worsen caregiver burden, and are associated with significant psychiatric comorbidity...

In archeology or forensics, the analysis of the ilia is often used to determine the age and sex of unknown individuals. However, sex determination using the skeletal remains of individuals who did not develop secondary sexual characteristics remains controversial. Accurately estimating the sex of subadults is hampered by a small number of studies based on identified skeletal collections of juvenile individuals. Here, we analyzed the sexual dimorphism of the subadult ilia using geometric morphometric techniques and individuals from the osteological collection of identified subadults from San José's graveyard (Granada)...

BACKGROUND: Over the past several decades, the age of pubertal onset in girls has shifted downward worldwide. As early pubertal onset is associated with increased risky behavior and psychological issues during adolescence and cardiometabolic disease and cancer in adulthood, this is an important public health concern. Exposure to endocrine disrupting chemicals during critical windows of in utero development may play a role in this trend. Our objective was to investigate trimester-specific phthalate and BPA exposure in relation to pubertal development among girls in the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENT) birth cohort...

This cross-sectional study assesses the association between age of sexual initiation during adolescence and a selection of well-being outcomes regarding that first relationship. High-school adolescents from El Salvador (2,686) and from Peru (3,399) replied to a paper-pencil questionnaire. Those who were sexually initiated replied to several questions regarding their age at sexual initiation, condom use, satisfaction and reasons/circumstances for that sexual relationship. Approximately 19% of participants were sexually initiated (n = 1,179)...

REVIEW
Bradley R Williams, Janet Soojeung Cho
Natural aging brings reduced production of growth and sex hormones, beginning in middle age, with noticeable physiologic changes by the sixth or seventh decade of life: reduced muscle mass, energy, and exercise capacity and alterations in sexual function. Hormones and hormone precursors have been investigated to delay changes in body composition, strength, and physical and cognitive function. Menopausal hormone therapy is effective for vasomotor and genitourinary symptoms. Testosterone is effective in men with hypogonadism and declines in physiologic function...

BACKGROUND: Female sex workers (FSWs) have been identified as a core group in the transmission of HIV and other sexually transmitted infections (STIs). Young FSWs are particularly more vulnerable to HIV due to the combination of vulnerabilities associated with their youth and the sex work they engage in. This study aims to give more insight into HIV prevalence and sexual risk behaviour of young FSWs in Nigeria, by focusing on the differences between BB and NBB young FSWs. METHODS: Data was obtained from the Nigeria Integrated Biological and Behavioural Surveillance Survey (IBBSS) for high-risk groups conducted in 2010...

BACKGROUND: Low sensitivity (LS) to alcohol's acute effects is a known risk factor for heavy drinking and its negative consequences. However, LS could be protective due to LS drinkers being less impaired at a given level of consumption. Here, we tested whether LS is associated with differences in men's and women's reports of alcohol-related regretted sex. METHODS: Eight hundred and one young adults (393 women) aged 21 to 35 (M = 23.11 years) recruited for a study of alcohol's effects on cognition completed self-report measures of alcohol sensitivity, typical alcohol use, and alcohol consequences (including regretted sex)...

CDC's 2006 recommendations for human immunodeficiency virus (HIV) testing state that all persons aged 13-64 years should be screened for HIV at least once, and that persons at higher risk for HIV infection, including sexually active gay, bisexual, and other men who have sex with men (MSM), should be rescreened at least annually (1). Authors of reports published since 2006, including CDC (2), suggested that MSM, a group that is at highest risk for HIV infection, might benefit from being screened more frequently than once each year...

Focus group methods were used to explore heterosexual women's receptive anal sex attitudes and motivations. Behaviors under investigation included penile-anal intercourse (PAI), manual-anal stimulation, oral-anal contact, and the use of sex toys. A total of 33 self-identified heterosexual women ages 18 to 30 recruited from two metropolitan areas in the Midwestern United States participated in one of six focus groups. The findings suggest that women viewed heterosexual anal sex as an emerging norm. Attitudes and motivations were complex and varied by behavior...

In the USA, partner non-monogamy is reported to be more common among African American women than White women and may contribute to African American women's increased risk for HIV and other sexually transmitted infections (STIs). Few studies have explicitly and comprehensively described the protective behaviours that African American women employ with non-monogamous partners to reduce their HIV risk. We conducted interviews to examine protective behaviours among 11 African American women aged 18-24 years who perceived that a partner in the preceding 12 months had another sex partner...
