Immediate Seven Day Outcomes and Risk Factors of Low Birth Weight Neonates at Referral Hospitals in Mwanza City, Tanzania in October 2020

Abstract

Background:
Every year more than 20 million neonates worldwide are born with low birth weight (LBW) per year. Ninety-five percent of LBW births occur in developing countries. The aim of this study was to determine Immediate Seven Day Outcomes and Risk Factors of Low Birth Weight Neonates at Referral Hospitals in Mwanza City.
Materials and Methods:
This was a hospital based observational prospective cohort study of neonates with LBW whom were followed up for seven days in the neonatal wards at referral hospitals in Mwanza city. Maternal social-demographic, newborns clinical data and vitality outcomes were collected. Categorical and continuous variables were summarized and presented in tables or bar charts. Any p-value of < 0.05, at 95% confidence interval was regarded as statistically significant.
Results:
Total of 200 neonates with median age of 0.8 days at baseline were enrolled. Amongst 148 (74 %) had prolonged hospitalization; due to sickness 88 (59%), and 60 (40%) due to poor weight gain. Whereas, the remaining 42 (21%) were discharged and 10 (5%) died within seven days. Prolonged hospitalization was associated with family income (p-value= <0.001) and place of delivery (p-value = <0.001). Neonatal death was associated with family income (p-value =0.035) and birth weight (p-value = 0.019). Early discharge associated with gestational age at first antenatal visit, family income, mode of delivery, APGAR score at one minute, time interval between delivery and admission and timing of medication initiation.
Conclusion:
LBW neonates are at high risk of death and prolonged hospitalization due to sickness or due to poor weight gain. Associated factors of these outcomes were family income, place of delivery, birth weight, gestation age during first antenatal visit, mode of delivered and low APGAR score.
