Objective: Inspite of unquestionable progress, the protection of girls at first sexual intercourse is still not perfect. The main risks are well known (sexually transmitted infections [STIs], unwanted pregnancies, psychological consequences) and seem to be higher in the case of early sexual initiation. The aim of this epidemiological study is to analyse factors associated with early heterosexual intercourse (age 15 or before) among girls, considered as risk factors for pregnancies and STIs.
Population And Methods: Our data come from the 2002 international survey Health Behaviour in School-aged Children (HBSC)/WHO. The questionnaire is completed anonymously in class and measures health, health behaviours and their contexts among 11-, 13- and 15-year-old students. Only the 15 year-olds are asked about their sexual behaviour. In France, 1264 15-year-old (plus or minus six months) girls have answered the survey.
Results: Two hundred and twenty-four girls (17,7 %) state they have already had sexual intercourse. Among these, 88,4 % say that condoms and/or pills were used at last sexual intercourse. Multivariate analysis (n=1159) show that seven variables are significantly and independently linked to a higher frequency of early sexual intercourse: single-parent or reconstructed family, repeated drunkenness, daily smoking, cannabis experimentation, frequent evenings out, negative life appreciation and early menarche.
Discussion And Conclusion: Identifying factors associated with early sexual initiation should help professionals to better take care of those high risk adolescent girls.

Compared to our closest primate relatives, human life history involves greater longevity, which includes a distinctive postmenopausal life stage. Given mammalian reproductive physiology in which females build a finite stock of cells that can become oocytes early in life, which then continuously deplete mostly through cell death while males produce new sperm throughout adulthood, the postmenopausal stage makes the sex ratio in the fertile pool, called the adult sex ratio (ASR), male biased. Additionally, this affects a more fine-grained ratio, the operational sex ratio (OSR), defined as the ratio of males to females currently able to conceive.

Cervical cancer is the second most common malignancy among South African women and the load of abnormal cervical smears has clinical, programmatic and policy implications. This cross-sectional study of women who presented for cervical cancer screening aimed to determine the prevalence of abnormal cervical smears and associated factors in primary health care (PHC) facilities in Gauteng-the most densely populated province in South Africa. A questionnaire collected data on socio-demography, tobacco use, sexual behaviours, HIV status, past treatment for sexually transmitted infections (STI) and cervical cancer screening in the past 10 years.

Background: Despite global declines in cervical cancer incidence, certain regions observe unexpected rising trends among younger generations.
Methods: This study uses the age-period-cohort model to examine long-term incidence trends of invasive cervical cancer in Taiwan. Data were sourced from the Taiwan Cancer Registry.

The term early life stress encompasses traumatic events occurring before the age of 18 years, such as physical abuse, verbal abuse, household dysfunctions, sexual abuse, childhood neglect, child maltreatment, and adverse childhood experiences. Adverse psychological experiences in early life are linked to enduring effects on mental and physical health in adulthood. In this review, we first describe the effects and potential mechanisms of early life stress on the components of the vasculature.

, the bacteria that causes syphilis, is typically acquired through sexual contact but can also be transmitted transplacentally (through the placenta), causing congenital infection. Syphilis in pregnancy is a major contributing factor to perinatal morbidity and mortality. Untreated neonates may develop complications affecting the central nervous system, bones, joints, teeth, eyes, and skin.
