Item Gender and rural-urban differences in the nutritional status of in-school adolescents in south-western Nigeria(Cambridge University Press, 2010) Omigbodun, O.O.; Adediran, K.I.; Akinyemi, J.O.; Omigbodun, A.O.; Adedokun, B.O.; Esan, O.B.This study assessed gender and rural/urban differences in height and weight, and the prevalence of stunting, underweight and overweight of school-going adolescents in south-west Nigeria, using 2007 WHO reference values for comparison. The influence of sexual maturity and the socio demographic correlates of growth performance were also examined. In this cross-sectional study, 924 male (51.4%) and 875 female (48.6%) students (1799 in total) aged 10–19 years from eighteen schools in Ibadan (five rural, nine urban public and four urban private) were interviewed and examined. Although males were significantly taller than females (p<0.05) stunting was more pronounced for males, who were 7.5 cm shorter than the 2007 WHO reference, compared with females who were 3.5 cm shorter. Body mass index (BMI) for girls was also greater than for boys (p<0.05) Rural adolescents had lower heights and BMIs compared with those in urban areas. The mean height of male adolescents in rural schools fell below 2 SDs of the 2007 WHO reference between 14 and 17 years, while heights of males and females in private schools were similar to the median 2007 WHO standard. Low height-for-age was observed in 282 adolescents (15.7%), which, after multivariate analysis, was significantly associated with school type, gender, number of mother’s children and puberty onset. Adolescents in rural schools were much more likely to be stunted than those in urban private schools (AOR 13.1; 95% CI 5.2–33.2) and males were three times more likely to be stunted compared with females (AOR 3.3; 95% CI 2.4–1.4). Low BMI-for-age was observed in 240 adolescents (18.9%), with correlates similar to stunting. Adolescents at the pre-puberty stage were twice as likely to have low BMI-for-age (OR 2.0; 95% CI 1.6–2.5) than those with signs of puberty. There were 2.3% overweight adolescents, who were significantly more likely to be female, in private school and post-pubertal. Innovative interventions for Nigerian adolescents, especially rural inhabitants and males, are needed to reduce the prevalence of stunting and underweightItem Sexual behaviour and contraceptie usage of secondary school adolescents in Ibadan, Nigeria(2007-12) Oladokun, A.; Morhason-Bello, I.O.; Enakpene, C. A.; Owonikoko, K.M.; Akinyemi, J.O.; Obisesan, K.A.Objective To determine the prevalence and pattern of sexual activity as well as the contraceptive practices among the selected secondary school adolescents in Ibadan, Nigeria. Methods A descriptive cross-sectional study was conducted among the selected senior secondary school students in Ibadan, Nigeria, following a stratified multistage random sampling technique. Results There were 695 respondents out of which the females constituted 51% and the males were 49%. Less than one third (28.3%) of the respondents have had previous sexual exposure at the time of the study. The median age of sexual debut among the sexually exposed was 15 years in both the males and the females. Bivariate analysis of sociodemographic characteristics of respondents with previous sexual exposure showed that, sex, religion, father’s and mother’s educational background and level of class were statistically significant(P<0.001). Further analysis using logistic regression model revealed that male respondents were 3 times more likely than females (95% CI 1.92-4.56) to have had sexual experience while those whose mother had tertiary educational background were less likely to have had previous sexual experience compared to those with secondary and lower educational background (OR= 1.76, 95% CI 1.11- 2.77). Of all the sociodemographic characteristics of respondents considered with the age of sexual partners using bivariate analysis showed that only level of class was significant (P=0.018). Less than half of the sexually active males (44.2%) were using modern method (male condom) of contraception, while 54.4% of the sexually active females were using different types of modern methods. Conclusion It is quite obvious that risky sexual behaviors are in practice among the secondary school students studied and by extension in the country. It therefore means that reproductive health issues especially concerning the adolescents will have to be openly discussed by all with our youths while abstinence/chastity should be cherished
