Mediation of effects of a theory-based behavioral intervention on self-reported physical activity in South African men.

Objective: Increasing physical activity is an important public-health goal worldwide, but there are few published mediation analyses of physical-activity interventions in low-to-middle-income countries like South Africa undergoing a health transition involving markedly increased mortality from non-communicable diseases. This article reports secondary analyses on the mediation of a theory-of-planned-behavior-based behavioral intervention that increased self-reported physical activity in a trial with 1181 men in Eastern Cape Province, South Africa.

Method: Twenty-two matched-pairs of neighborhoods were randomly selected.

Theory-based behavioral intervention increases self-reported physical activity in South African men: a cluster-randomized controlled trial.

Objective: To determine whether a health-promotion intervention increases South African men's adherence to physical-activity guidelines.

Method: We utilized a cluster-randomized controlled trial design. Eligible clusters, residential neighborhoods near East London, South Africa, were matched in pairs.

Protective factors and HIV risk behavior among South African men.

The primary mode of HIV transmission in South Africa is heterosexual sexual behavior. HIV prevention research specifically focusing on men in South Africa is limited. We assessed self-reported HIV risk behaviors in 1,181 men ages 18 to 45 years in randomly selected neighborhoods in Eastern Cape Province, South Africa.

Cluster-randomized controlled trial of an HIV/sexually transmitted infection risk-reduction intervention for South African men.

Objectives: We tested the efficacy of a sexual risk-reduction intervention for men in South Africa, where heterosexual exposure is the main mode of HIV transmission.

Methods: Matched-pairs of neighborhoods in Eastern Cape Province, South Africa, were randomly selected and within pairs randomized to 1 of 2 interventions based on social cognitive theory and qualitative research: HIV/sexually transmitted infection (STI) risk-reduction, targeting condom use, or attention-matched control, targeting health issues unrelated to sexual risks. Sexually active men aged 18 to 45 years were eligible.
