Early Sexual Initiation

Background Early adolescence is a critical stage in adolescents. This is the phase at which many young people start their sexual life early, increasing the risk of sexually transmitted infections and unintended pregnancy. Few studies have analyzed the factors associated with early sexual initiation in very young adolescents in low- and middle-income countries. Therefore, this study assessed the early sexual initiation stratified by sex and its correlates in a sample of Brazilian adolescents. Methods The study sample included Brazilian adolescents aged 12–14 who participated in The Study of Cardiovascular Risk in Adolescents (ERICA), a multicenter, school-based, country-wide, cross-sectional study. Early sexual initiation was defined as the first sexual intercourse at or before 14 years old. Multivariate logistic regression was used to identify independent factors associated with early sexual initiation. Results The prevalence of early sexual initiation was 7% among girls and 18% in boys. In a multivariate analysis, the adolescent’s age, mother’s schooling, smoking, alcohol consumption, and Tanner Stages were associated with early sexual initiation for both boys and girls. For girls, living with both parents, common mental disorders, and age at menarche were predictors of early sexual initiation, while race and type of school were correlated to early sexual initiation only for boys. Conclusions The early sexual initiation was associated with sociodemographic, lifestyle risk factors and secondary sexual characteristics in both sexes, while there were differences between the predictors of early sexual initiation among girls and boys. It emphasizes the importance of sex education and promotes healthy lifestyles in environments through families and schools in early adolescence.

Age Of Menarche

Background: Present study highlights that the worldwide trend of declining age at menarche is also seen in urban Indian girls. The aim of the study was to evaluate the age of menarche and to find out the factors associated with the timing of menarche.Methods: The study was an observational cross sectional study. 258 healthy, menstruating, adolescent girls aged 10-16 years, were selected by simple random sampling. Pre-designed structured questionnaires were distributed after taking informed consent. Anthropometric measurements were taken using standard techniques. The average age of menarche was calculated. The association of the age at menarche with the proposed factors was analyzed using chi square test and Pearson’s correlation coefficient. “P value” less than 0.05 was considered as significant.Results: The mean age at menarche was found to be 12.23±1.09 years. The study found a strong association between the respondent’s age at menarche and her sister’s age at menarche (p=0.002). The study also found a strong association between age at menarche and the socioeconomic status (p=0.021). This study however found no association of menarcheal age with factors like birth weight, type of diet, frequency of milk intake, body mass index, waist hip ratio, amount of exercise, unstable environment at home and psychosocial stress.Conclusions: The worldwide trend of declining age at menarche is also seen in urban Indian girls. This trend underlines the importance of investigating the factors associated with it and studying the future implications of a lower age at menarche.

Abstract Background: To determine the prevalence of premarital sex and its risk factors in Nepal.Methods: A cross-sectional study was carried out among adolescents in Nepal. A self-administered questionnaire was used to collect information from 6,147 unmarried adolescents. Random sampling by using a lottery method was applied to select 20 colleges from all three districts. All the students who were studying at those colleges were enrolled in the study. Simple and multivariate logistic regression analyses were carried out to analyse the associations of risk factors and premarital sex.Results: The prevalence of premarital sex was 38.1%. Male students were more likely to engage in premarital sex (adjusted odds ratio [AOR]=2.04, confidence interval [CI]=1.76-2.36) than female students. Alcohol consumption (AOR=1.26, CI=1.08-1.47), smoking (AOR=1.69, CI=1.41-2.02), drug use (AOR=1.85, CI=1.23-2.83), going to night clubs (AOR=1.46, CI=1.24-1.70), clothing style of girls AOR=1.35, CI=1.15-1.58), clothing style of boys (AOR=3.51, CI=2.74-4.53), and unmarried friends having sex (AOR= 1.51, CI=1.31-1.73) were found to be major influencing factors for premarital sex. Moreover, students who had never received sex education were 2.92 times more likely to engage in premarital sex (CI=2.22-3.85) than those who had previously received sex education.Conclusions: We found several risk factors associated with premarital sex in Nepal. Preventing premarital sex may require the promotion of sex education.

Abstract Objective: to identify risk factors related to overactive bladder syndrome. Method: a cross-sectional study was performed with elderly women (>60 years) from the community of Ceilândia, in the Distrito Federal, Brazil, with or without symptoms of OBS, who were evaluated through interviews and questionnaires. The clinical and sociodemographic variables analyzed were: age; body mass index (BMI); parity, schooling, previous abdominal and urogynecologic surgeries, physical activity, smoking, constipation, systemic arterial hypertension (SAH), diabetes mellitus; depression and anxiety. The questionnaires applied were the Overactive Bladder Awareness Tool (OAB-V8), the Geriatric Depression Scale and the Beck Anxiety Scale. Data were analyzed descriptively. Binary logistic regression was used to evaluate the significant associations between the independent variables and the outcome of interest. Risk ratios were calculated for each independent variable with 95% confidence intervals. Result: A total of 372 volunteers were recruited, 292 of whom were eligible. Of these, 172 were allocated to the case group (58.9%) and 120 (41.1%) were control subjects. The two groups were homogeneous between one another. There was a high prevalence of OBS in the study population and significant differences for the variables presence of SAH, abdominal surgery and pelvic surgery, with the case group presenting a higher frequency of these events. In multivariate analysis, it was observed that an active sexual life reduces the chance of having OBS by 70.8%, while urogynecologic surgeries increase this risk 3.098 times. Conclusion: In univariate logistic regression analysis, BMI, SAH, a previous history of abdominal and urogynecologic surgery, number of abortions and the presence of symptoms of depression and anxiety, were found to be factors associated with OBS.

Abstract Objective: To estimate the prevalence of probability of common mental disorders in pregnant women and associated factors. Methods: A cross-sectional study with a quantitative and descriptive approach was performed with 330 pregnant women enrolled in a Women's Health Service located in Mid-West Brazil. Data were obtained through a questionnaire about socio-demographic characteristics and family or personal history. The Self-Reporting Questionnaire and Poisson regression were applied to screen for common mental disorders, aiming to identify factors associated with it. Results: The prevalence of probability of common mental disorders among pregnant women was 57.1% and it was associated with marital status, gestational age, unplanned pregnancy and bleeding. Conclusion: The prevalence of pregnant women likely to have common mental disorders and the average Self-Reporting Questionnaire score estimated in this study were higher than those found in other studies with samples from the general population.
