Universal home visits improve male knowledge and attitudes about maternal and child health in Bauchi State, Nigeria: Secondary outcome analysis of a stepped wedge cluster randomised controlled trial.

BACKGROUND

The World Health Organization recommends increased male involvement to improve maternal and newborn health in low- and middle-income countries, but few studies have measured the impact of male-engagement interventions on targeted men. A trial of universal home visits to pregnant women and their spouses in Nigeria improved maternal and child health outcomes. This analysis examines the impact of the visits on male spouses.

METHODS

In Toro Local Government Area in Bauchi State, Nigeria, we randomly allocated eight wards into four waves, beginning the intervention at one-year intervals. The intervention comprised two-monthly evidence-based home visits to discuss local risk factors for maternal and child health with all pregnant women and their male spouses. Measured secondary outcomes of the intervention in the men included knowledge about danger signs in pregnancy and childbirth, beliefs about heavy work in pregnancy, discussion with their wives about pregnancy and childbirth, knowledge about causes and intentions about management of childhood diarrhoea, and views about childhood immunisation. The analysis compared outcomes between men in visited wards (intervention group) and pre-intervention wards (control group), using a cluster test. Generalised linear mixed modelling accounted for the effect of socio-economic differences on the measured impact.

RESULTS

The analysis included 6931 men in the intervention group and 9434 in the control group. More men in the intervention group knew four or more danger signs in pregnancy (risk difference (RD) = 0.186, 95% confidence interval (CI)  = 0.044 to 0.327), and three danger signs in childbirth (RD = 0.091, 95%CI = 0.013 to 0.170), thought pregnant women should reduce heavy work before the third trimester (RD = 0.088, 95% CI = 0.015 to 0.162), and had discussed pregnancy and childbirth with their spouse (RD = 0.157, 95% CI = 0.026 to 0.288). More knew correct management of childhood diarrhoea with fluids and feeding (RD = 0.300, 95% CI = 0.203 to 0.397) and less would give a child medicine to stop diarrhoea (RD = 0.206, 95% CI = 0.125 to 0.287). Socio-economic differences did not explain the effect of the intervention on any of the outcomes.

CONCLUSION

Universal home visits improved knowledge of male spouses about maternal and child health, which could contribute to improved maternal and child outcomes.
