Effectiveness of the intervention on male partners’ knowledge of and attitude towards MWHs
REGRESSIONS
Health education intervention provided to couples significantly improved male partners’ knowledge of and attitude towards MWHs. Male partners’ knowledge about MWH was increased by 39.4% in the intervention group, while it was increased by 3.8% in the control group. Thus, the net effect (diff-in-diff) of the intervention on increasing good knowledge about MWH was 35.6% (95% CI 31–40.2%, p < 0.001) among male partners. Likewise, the level of favorable attitude towards MWH among male partners’ was increased by 40.6% in the intervention group, whilst it was increased by 4.4% in the control group. As a result, the net effect of the intervention on increasing favorable attitude towards MWHs was 36.2% (95% CI 31.1–41.3%, p < 0.001) (Table Statistical summary of the outcome variables from a cluster-randomized trial in rural Ethiopia, Sep 15, 2022 to Apr 30, 2023.Moreover, generalized linear model regressions were performed to compare the odds of outcomes between the intervention and control groups both at baseline and endline. At baseline, the odds of having good knowledge about MWH (AOR: 1.11, 95% CI 0.71–1.74, P = 0.46), and favorable attitude towards MWH (AOR: 1.18, 95% CI 0.74–1.88, p = 0.48) did not show statistically significant difference between the groups. However, at the endline, male partners in the intervention group were 5.5 times more likely to have good knowledge about MWHs (AOR: 5.55, 95% CI 3.37–9.14, p < 0.001), and 5.6 times more likely to have favorable attitude towards MWHs (AOR: 5.61, 95% CI 3.45–9.10, p < 0.001) compared to those in the control groups.
