Who uses covertly and what is the impact on contraceptive dynamics? Evidence from a national cohort of women in Uganda

Abstract

Background: Little is known regarding the specific role of covert use (i.e., use of contraception without partner knowledge) in contraceptive discontinuation and switching. Among a nationally representative cohort of women in Uganda, we sought to: 1) compare characteristics of covert, overt, and non-users of contraception at baseline; 2) assess the effect of using contraception covertly on switching and discontinuation over a one-year period. Methods: Analyses utilized PMA2020 Uganda Round 6 (April–May 2018), with longitudinal analyses incorporating data from a one-year follow-up survey (May–June 2019). Both cross-sectional (n=1,764) and longitudinal (n=616) samples included women in need of contraception. For cross-sectional analyses, multinomial regression compared risk of overt/covert use vs. non-use by user characteristics and logistic regression compared the odds of covert vs. overt use among contraceptive users. For longitudinal analyses, multinomial regression examined risk of contraceptive switching and discontinuation by baseline covert vs. overt use status. Results: Among contraceptive users, 14.1% reported using covertly. In cross-sectional analyses, higher wealth (aRRR=1.74; 95% CI=1.19-2.54), secondary or higher education (aRRR=2.52; 95% CI=1.42-4.49), and middle parity (aRRR=1.24; 95% CI=1.00, 2.28) were associated with an increased risk of overt use, and higher wealth (aRRR=2.08; 95% CI=1.09-3.98) and polygyny (aRRR=1.60; 95% CI=1.01-2.54) with covert use, compared to non-use. Among contraceptive users, women within polygynous unions had double the odds of using covertly compared to those with monogamous partners (aOR=1.97; 95% CI=1.28-3.03). Longitudinal analyses revealed large proportions of overt and covert users switched (30% overt, 26% covert) or discontinued methods (32% overt, 37% covert) at one-year follow-up, however, neither switching nor discontinuation was significantly related to overt/covert use status at baseline. Conclusions: Though significant differences by covert use status were not detected, approximately 33% of users discontinued over one year; these women represent important beneficiaries of family planning programming as they may remain at risk for unintended pregnancy.
