In 2005, more than 25 million adults and children worldwide were living with HIV/AIDS and more than 75% of these were in sub-Saharan Africa. Studies indicate that the incidence of HIV infection and the prevalence of high-risk behaviors among young populations continue to rise in developing countries. AIDS has severe economic impacts, especially in high-risk countries such as Nigeria. This project used secondary data from the 2003 Nigeria Demographic and Health Survey. The 2003 NDHS is a cross-sectional, multistage, stratified survey with systematic sampling that was designed to obtain information on key population and health indicators such as sexual activity, knowledge about AIDS and other STDs, and behavior associated with AIDS and other STDs for the entire Nigerian population, including people living in rural areas, urban areas, and six major geographic regions. Analyses were restricted to sexually active adolescents and young adults 15 to 24 years of age who are Nigerians living in Nigeria in 2003. The sample size was (n=2,418), of which 2,009 are females and 409 are males. Non-Nigerians and Nigerians in Diaspora were excluded in the original design of the survey. Also, those younger than 15 years or older than 24 years were excluded in this study. This research examined the association between independent variables and other covariates with risky sexual behaviors such as lack of condom use and multiple sex partners, as well as possible difference by gender. Odds ratios (ORs) were calculated using multivariate logistic regression models, adjusting for age, education and religion. All tests were done at 95% significant leve. l-- Abstract.

The descriptive survey design was used for the study. A study sample of 378 adolescents in Akoko Northwest Local Government Area of Ondo State were randomly selected using the multi-stage random sampling technique.

Retrieval of instrument from respondents was immediate yielding a 100% return rate. SPSS was then combined with EPI Info to make a comprehensive result that was outlined in the results section. Descriptive statistics such as frequencies and percentage distribution was used to show the distribution of the study population according to selected study variables. There is no evidence of association between adolescents’ gender, class, and ethnicity while there is an association between adolescents’ age, religion and adolescent sexual behaviour. That majority of the adolescents were aware of HIV, Majority of the adolescents were aware of HIV/AIDS via peer group, Major prevalent risky sexual behaviours among adolescents is virginal sex, Majority of the respondent had their first sex at age 11-13 years, Majority of the respondent had never used condom.There is significant association between the level of awareness of HIV/AIDS and prevalent risky sexual behaviours of the adolescent.

It is universally agreed that HIV/AIDS constitutes one of the most serious threats to human life in our era. The immigration of Zimbabwean people into America plays a major role in the socialization of Zimbabwean adolescents. Zimbabwean adolescents are exposed to the Western culture of sexual socialization, which is different from the African culture. The social bonds and traditions that used to shape Zimbabwean young people's behavior and help them make the transition to adulthood have weakened in the face of migrating to Western countries. The main problem is the transition and loss of cultural identity that affect Zimbabwean adolescents' knowledge of HIV/AIDS transmission and sexual behavior.

The AIDS epidemic in Sub-Saharan Africa continues to affect all facets of life throughout the subcontinent. Deaths related to AIDS have driven down the life expectancy rate of residents in Zambia, Kenya, and Uganda with far-reaching implications. This book details the current state of the AIDS epidemic in Africa and what is known about the behaviors that contribute to the transmission of the HIV infection. It lays out what research is needed and what is necessary to design more effective prevention programs.
