Abstract

Background: Despite low birth weight (LBW) role on child growth, development, and survival in developing countries, it has not been given the desired priority in terms of research, at the national level in Nigeria. Our study aims to estimate the trend in the prevalence of small size babies and to identify its predictors using nationally representative data.

Methods: We used the 2013 and 2018 data from the Nigeria Demographic and Health Survey using the statistical methods of descriptive analysis and logistic regression modelling.

Results: The proportion of babies reported to have small size at birth in Nigeria declined from 14.9% in 2013 to 13.7% in 2018. Various factors from demographic, socio-economic, and health-seeking behaviour were identified as significant predictors. Women who received iron pills and tetanus toxoids during pregnancy had at most 79% and 80% less risk of having small size babies, respectively, than those who received none of these two. Female children had at least 21% more chance of being small in size than male children. Other key predictors were geopolitical region, maternal age at child birth, maternal literacy level, wealth status, religion, source of water supply, number of ANC visits during pregnancy, and desirousness of pregnancy.

Conclusion: In light of the adverse effects of low birth weight on child well-being, we recommend the implementation and prioritization of active, resourceful public health interventions that account for the findings of this study, if Nigeria is to sustain the progress achieved so far in reducing its current high rate.
