Effect of health education provided to couples on maternal knowledge, attitude and use of maternity waiting homes in rural Ethiopia: A cluster-randomized trial

Background: Maternity waiting home (MWH) has been advocated as an approach to improve women's access to obstetric services in low-resource settings; however, its use remains low. This study investigated the effectiveness of couple-based health education on maternal knowledge, attitudes, and use of MWHs in rural Ethiopia. Methods: A total of 320 couples from 16 clusters were allocated to the intervention and control groups using restricted randomization. Participants in the intervention group received group health education, home visits, and information flyers along with usual care, whereas those in the control group received usual care. Statistical differences were estimated using the chi-squared test. The impact of the intervention was evaluated using generalized linear regression and difference-in-differences models. Results: Baseline and endline data were collected from the 320 couples. The intervention increased knowledge by 37.5 % (95 % CI: 32.2 % - 42.8 %), attitude by 33.8 % (95 % CI: 28.8 %–39.2 %), and utilization of MWH by 32.9 % (95 % CI: 27.9 %–38.2 %) among women. In addition, compared to those in the control group, women in the intervention group were almost six times more likely to have increased knowledge of MWH (AOR 5.74, 95 % CI: 3.51–9.38), four times more likely to have improved attitudes of MWH (AOR 4.45, 95 % CI: 2.78 -7.13), and four times more likely to stay at MWH (AOR 4.45, 95 % CI: 2.78 -7.12). Conclusion: Providing health education to couples can improve maternal knowledge, attitudes, and the use of MWHs. Policymakers and healthcare cadres can use the current intervention strategy to enhance maternal health services, particularly MWHs, in rural Ethiopia.
