Reducing stunting and underweight through mother's birth spacing: evidence from Ghana

Researchers over the years have underscored the role of birth spacing on maternal health, however, inadequate maternal repletion due to shorter birth intervals could also affect the health of the child. Even so, limited studies exist on the linkage between birth spacing and child nutrition. This study examines the association between birth spacing and child stunting and underweight using the 2014 Ghana Demographic and Health Survey.

The study sourced data on 1, 904 children less than 59 months from the 2014 Ghana Demographic and Health Survey. The study employed bivariate analysis and logistic regressions to establish the association between birth spacing, and child stunting and underweight.

The analyses reveal that childbirth spacing between 24 and 35 months (OR = 0.62, 95% CI: 0.38-0.99; p < 0.05), 36 to 47 months (OR = 0.42, 95% CI: 0.25-0.70; p < 0 0.01), and beyond 47 months (OR = 0.47, 95% CI: 0.28-0.78; p < 0.01) have lower odds of child stunting than children with birth spacing less than 24 months. Children with birth spacing between 24 and 35 months (OR = 0.53, 95% CI: 0.29-0.98; p < 0.05), 36 to 47 months (OR = 0.44, 95% CI: 0.22-0.90; p < 0.01) and beyond 47 months (OR = 0.49, 95% CI: 0.26-0.94; P < 0.05) have lower odds of being underweight than those with birth spacing less than 24 months.

The study reveals that mothers with a birth spacing of at least two to three years compared to their counterparts with less than two years of birth spacing have lower odds of having a stunted and underweight child under age five. The study recommends that Ghana Health Service and other healthcare providers should educate mothers on the gains of birth spacing of at least two years on their children.
