Factors associated with sexual and reproductive health service utilisation in high migration communities in six Southern African countries

BACKGROUND: Migration among women has significant health consequences on their access to and utilisation of health services, particularly sexual and reproductive health services. Despite the large quantity of research on migrant health, there is a paucity of research on the factors associated with utilization of modern methods of contraception, intimate partner violence services and sexual and reproductive health (SRH) referral services among non-migrants, internal and international migrant women. Consequently, understanding the factors associated with utilisation of SRH services among women in Southern Africa motivates this study. METHODS: The study uses secondary data from a cross sectional survey conducted in 2018. Logistic regression models were fitted to investigate the factors associated with utilisation of sexual and reproductive health services among 2070 women aged 15–49 years in high migrant communities in six Southern African countries. RESULTS: Factors found to be associated with current non-use of modern contraceptive methods were country, employment status, educational level, comprehensive knowledge about SRH, comprehensive knowledge about HIV, desire for another child, partner’s age and partner’s educational level. Regarding utilisation of SRH services, important factors were ever denied access to a public healthcare facility, country, marital status and comprehensive knowledge about HIV. Factors associated with utilising IPV services were migration status, age and attitude towards wife beating. CONCLUSION: The findings highlight that migration status is associated with utilisation of IPV services. Comprehensive knowledge about SRH and partner characteristic variables were associated with current non-use of modern contraceptive methods. There is a need for SRH programs that can disseminate accurate information about SRH and encourage male involvement in SRH related issues. In addition, the SRH programs should target all women regardless of their migration status, age, educational level and marital status.
