Maternal Health Services as Determinant Factors for Low Birth Weight in public hospitals of Addis Ababa, Ethiopia: a Case-control Study.

Abstract Background: The birth weight of a newborn has a substantial impact on infant mortality, morbidity, development, and long-term health. It is determined by the mother's overall health status. More than 20 million babies are born with low birth weight across the world. In developing countries, almost 17% of all newborns are born with low birth weights, with no exception in Ethiopia. Alleviating this problem, needs a clear understanding of the determinants. Thus, this study was done in Addis Ababa, the most populous city in the country, where the lifestyles of mothers might be affected by the dynamic city life.Method: An unmatched case-control study was applied to assess the risk factors of low birth weight in three randomly selected public hospitals in Addis Ababa, Ethiopia. Data was collected through interviewer-administered structured questionnaires. Data analysis was done using SPSS version 24. Descriptive statistics using frequencies and percentages were used to describe the socio-demographic characteristics of the study participants. Bi-variable and multi-variable logistic regression analyses were used to assess the possible effect of determinant factors on low birth weight, with their respective odds ratios and 95% confidence intervals. P-values of less than 0.05 were considered statistically significant.Result: We enrolled 168 cases and 336 controls; all completed the study with no refusal. Of all pregnancies, 90 (17.8%) were unplanned and unwanted. And, 153 (30.3%) of mothers have a history of prior abortion. Among the factors we studied, maternal age below 18 years (AOR: 2.69, 95% CI: 1.24, 5.84), unwanted and unplanned pregnancy (AOR: 1.25, 95% CI: 1.09, 2.66), ANC visit in the last pregnancy below three (AOR: 3.23, 95% CI: 1.61, 6.49), female neonate (AOR: 1.09, 95% CI: 2.04, 3.20), not supplemented with iron and folic acid (AOR: 3.11, 95% CI: 1.36, 7.11) and hematocrit level of < 30 (AOR: 2.29, 95% CI: 1.00, 5.22) showed a statistically significant association with low birth weight.Conclusion: This study demonstrates that the age of mothers below 18 years, unwanted and unplanned pregnancy, low ANC visits, lack of iron and folic acid supplements, and low maternal hemoglobin level were the significant determinants of low birth weight among term babies. Thus, women of childbearing age should be screened and educated about the risks of pregnancy and should get the necessary care and support when they get pregnant.
