Sexual behavior of in-school adolescents in Osun State, Southwest Nigeria: a comparative study.

OBJECTIVES: The sexual and reproductive health of adolescents is of utmost importance in many nations (especially in developing countries). Sexual behavior varies from location to location and the outcome (when negative) creates great concerns mainly due to the consequential impact on health and development. This study aimed at comparing sexual behavior of in-school adolescents in rural and urban areas of Osun state. METHODS: A comparative cross sectional study was conducted. A total of 760 in-school adolescents were recruited using multistage sampling technique. Pre-tested questionnaires were administered after ethical considerations. Data were analysed and p-value was placed at 0.05. RESULTS: A total of 380 rural and 380 urban adolescents participated in this study with a mean age of 14.90 ± 2.44 and 14.34 ± 2.31 years, respectively. About one-fifth (20.1%) had experienced their first sex (66% of rural and 34% of urban). The mean age at first sex was 14.05 years ± 2.3 years (13.89 ± 2.3 years for rural and 14.37 ± 2.3 years for urban). Only 76 (49.7%) sexually experienced respondents had used condom in the past (45.5% of rural, 57.7% of urban). Half of the urban respondents used condom during their first sex while only a quarter of their rural counterparts had done so (p=0.003). CONCLUSION: Sexual behavior was commoner among the rural respondents than their urban counterpart. There is an urgent need for sexuality education especially among rural adolescents in the study area.

Prevalence of obesity among adolescents in Ile-Ife, Osun state, Nigeria using body mass index and waist hip ratio: A comparative study.

BACKGROUND: Obesity is a global epidemic not just among adults but also among children and adolescents. This study described the prevalence and pattern of obesity among in-school adolescents in Ile-Ife, Osun State using two standard methods, Body Mass Index (BMI) and Waist Hip Ratio (WHR) with a view of comparing the two methods as well as identifying any correlation between the two methods. MATERIALS AND METHODS: Five hundred male and female respondents, aged 10-19 years, were randomly selected through a multistage sampling technique from private and public schools in Ife Central Local Government Area. Quantitative data were collected with the aid of a pre-tested, semi-structured, self-administered questionnaire. Anthropometric measurements of respondents, BMI and WHR, were recorded. Chi square and linear regression analyses were used. Statistical significance was tested at the 5% level. RESULTS: The prevalence of obesity was 4.2% using BMI of which 12 (57.1%) were females and nine (42.9%) were males. There was significant association between sex and BMI, χ(2) = 9.490 (P = 0.020). Using WHR, the prevalence was 37.2% of which 180 (96.8%) were females and six (3.2%) were males. There was also significant association between sex and WHR (P < 0.001). Weak correlation (r = 0.02) was found between BMI and WHR among the females, P = 0.043. CONCLUSION: There was a difference in the prevalence of obesity using the two methods. Although, the correlation between the two methods was weak among females, WHR yielded a higher prevalence for obesity with remarkable difference especially among the females. Prevention of adolescent obesity should be encouraged especially among females.
