Women with diabetes are at high risk of adverse pregnancy outcomes if glycemic control is poor. Delaying pregnancy with effective contraception is crucial to allow diabetes to be optimised. Lack of encouragement and disapproval from the husbands leads to poor contraceptive use among women. Therefore, this study assessed the intention to use modern contraception among spouses of women with diabetes and its associated factors. A cross-sectional study was conducted in two clinics from December 2022 to March 2023. A total of 207 men aged 18 years and above, with wives having diabetes, within the reproductive age group were recruited. An online questionnaire was distributed, comprising sociodemographic characteristics, reproductive aspects, including intention for modern contraception use, past experience of contraception, spousal communication, a desire for children, and received contraceptive counselling. Knowledge of diabetes-related pregnancy risk and perception of contraception use in women were also included in the questionnaire. Only 52.7% of men had the intention. Educational level (AOR 2.41, 95% CI: 1.17-4.96), previous experience (AOR 3.3, 95% CI: 1.55-6.99), spousal communication (AOR 2.63, 95% CI: 1.19-5.85), wife’s age (AOR 0.94, 95% CI: 0.89-0.99) and perception towards contraception (AOR 0.98, 95% CI: 0.96-0.99) were the significant factors. Efforts should be made to ensure men have knowledge and correct perceptions towards contraception.
