Cognitive and behavioural determinants of multiple sexual partnerships and condom use in South Africa: Results of a national survey.

BACKGROUND: Human immunodeficiency virus (HIV) risky behaviours including multiple sexual partnership (MSP) and non-condom use (nCU) are known to be drivers of the spread of HIV; cognitive factors including perceived susceptibility of HIV, self-efficacy and attitudes play a significant role in influencing risky sexual behaviours. OBJECTIVES: We sought to investigate personal beliefs, perceptions, thoughts and actions that are associated with MSP and nCU in South Africa. METHODS: We analysed nationally representative data from the 2012 National HIV Communication Survey (NCS) that included about 10 000 participants aged 16-55 years. Five constructs were created to measure psychosocial and cognitive determinants. Cronbach's alpha coefficient for internal consistency reliability was calculated. Multivariable logistic regression was used to determine factors associated with MSP and nCU. RESULTS: Of the 6061 sexually active respondents, 13% (95% CI: 11.47-13.12) reported MSP and 52.7% (n = 3158 of 6039) (95% CI: 51.0-53.55) nCU at last sex. Factors associated with MSP included perceived benefits, adjusted odds ratio (aOR) = 2.16 (95% CI: 1.80-2.58), perceived susceptibility to HIV, aOR = 2.22 (95% CI: 1.83-2.69) and engaging in intergenerational sex, aOR = 2.14 (95% CI: 1.78-2.56). Predictors of nCU were perceived benefits, aOR = 1.25 (95% CI: 1.09-1.43); perceived susceptibility to HIV, aOR = 1.6 (95% CI: 1.39-1.83); and personal beliefs, aOR = 1.35 (95% CI: 1.13-1.62). CONCLUSION: Cognitive and behavioural factors were found to be predictors of risky sexual behaviours for HIV. This highlights the importance of considering personal perception and reasoning when attempting to understand and influence an individual's sexual behaviour. This could be done through enhancing awareness of HIV risk in the general population and by influencing cognitive behaviour change through community mobilisation, advocacy and creating activities to improve self-esteem.

Predictors of male condom use among sexually active heterosexual young women in South Africa, 2012.

BACKGROUND: In South Africa, young women are at disproportionate risk of HIV infection with about 2363 new infections per week in 2015. Proper condom use is one of the most effective HIV/AIDS prevention strategies among sexually active persons. Understanding factors associated with male condom use in this key population group is important to curb the spread of HIV. This study determined practices and predictors of male condom use among sexually active young women in South Africa. METHODS: The 2012 National HIV Communication Survey measured the extent of exposure to communication activities for HIV prevention among men and women aged 16-55 years in South Africa. We performed a secondary data analysis on a subset of this survey, focussing on 1031 women aged 16-24 years who reported having had sex in the past 12 months. We determined predictors of male condom use using the unconditional multivariable logistic regression model. RESULTS: Of the 1031 young women, 595 (57.8%) reported using a male condom at last sex, 68.4% in women aged 16-19 years and 54.5% in women aged 20-24 years (p < 0.001). Delayed sexual debut [20 years or above] (Adjusted Odds Ratio [aOR] 2.1, 95% CI: 1.2 to 3.7, p = 0.006); being a student (aOR 1.6, 95% CI: 1.2 to 2.3, p = 0.005); and exposure to HIV communication programmes (aOR 3.1, 95% CI: 1.2 to 8.6, p = 0.025) were significantly associated with male condom use at last sex. CONCLUSION: Male condom use was a common practice among young women and was associated with delayed sexual debut and exposure to HIV communication programmes. Behavioral interventions and HIV communication programmes should therefore encourage young women to delay initiation of sex and promote usage of male condoms.
