Contraceptive method and self-reported HIV status among women in Malawi.

OBJECTIVES: We aimed to describe contraceptive methods used by women in Malawi and determine whether contraceptive use differed by self-reported HIV status. Effective contraception is a primary method of preventing mother-to-child transmission of HIV.

STUDY DESIGN: Analysis is based on 12,658 nonpregnant, sexually debuted women ages 15-49 years in the 2010 Malawi Demographic and Health Survey. Analysis was restricted to respondents with contraceptive need (i.e., fecund and did not want a child in the next 12 months) who reported their last HIV test result. We accounted for the two-stage cluster sampling design by applying cluster, stratum and sample weights. We assessed differences in contraceptive method use by HIV status with χ2 tests and multivariable logistic regression.

RESULTS: A total of 893 (7.0%) of respondents reported being HIV positive. Use of long-acting reversible contraception (LARC) was low and did not differ between HIV-positive (1.4%) and HIV-negative (1.9%) women [adjusted odds ratio (aOR)=0.7, 95% confidence interval (CI), 0.4-1.4]. HIV-positive women (15.6%) were less likely than HIV-negative women (30.4%) to use progestin-only injectable contraception (aOR, 0.7; 95% CI, 0.5-0.8). Prevalence of female sterilization was higher among HIV-positive women (17.9%) compared to HIV-negative women (9.2%; aOR=1.7; 95% CI, 1.2-2.3).

CONCLUSIONS: LARC use was low among adult women with contraceptive need in Malawi. HIV-positive women were less likely to report progestin-only injectable use but more likely to report having undergone female sterilization compared to their HIV-negative counterparts. Noncoercive interventions that provide highly effective methods of contraception to HIV-positive women with contraceptive need are valuable methods of vertical transmission prevention in Malawi.

IMPLICATIONS: Contraceptive use differed by self-reported HIV status among adult women with contraceptive need in Malawi. Female sterilization was significantly higher, and use of progestin-only injectables was significantly lower, among HIV-positive women compared to their HIV-negative counterparts. Use of long-acting reversible contraception was low among both HIV-positive and HIV-negative women.
