Background: HIV prevalence in Zambia continues to be among the highest in Sub-Saharan Africa; estimates indicate that 16.5% of 15-49 year olds in Zambia are HIV+. The Health Communication Partnership (HCP) seeks to decrease HIV transmission through strengthening community-based systems and networks, mobilizing leaders and youth, and promoting the change of harmful social and gender norms. The objective of this study is to examine baseline determinants of condom use in HCP project areas in Zambia.

Methods: Using modified two-stage cluster sampling methodology, data were collected from 2005 baseline community-level (n=391), household-level (n=2,689) and individual-level (n=4, 431) surveys. Preliminary chi-square analyses were conducted; further analyses using multi-level logistic regression models will estimate the odds that a respondent reports condom use, controlling for combined effects of hierarchical socioeconomic and socio-demographic variables.

Results and Conclusions: Among females, 12.8% and 9.4% reported using a condom at last sex with casual and regular partners, respectively. Among males, levels were 28.8% and 9.4%, respectively, among casual and regular partners. Among both sexes, preliminary chi-square analyses indicate that the proportion of respondents using condoms at last sex with a casual partner differed by age (P<0.01), education (P<0.01), urban/rural residence (P < 0.05), radio listenership (P<0.01) and television viewership (P<0.01). For condom use at last sex with a regular partner, proportions differed by age (P<0.01), urban/rural residence (P < 0.05) and radio listenership (P<0.01) among males, and by urban/rural residence among females (P<0.01). Results will provide useful information for targeting and future evaluation of the HCP Zambia project.

Learning Objectives: By the end of the session, participants will be able to

• Identify key determinants of condom use with regular and casual partners.
• Describe a hierarchical framework for condom use in Zambia.
• Recognize strengths and limitations of hierarchical analysis for evaluating determinants of condom use with regular and casual partners.
