Low birth weight in newborns and associated maternal and neonatal factors in a colombian gineco-obstetrical hospital

Objectives To determine the prevalence of Low Birth Weight (LBW) in newborns treated at the Rafael Calvo Maternity Clinic (CMRC) during 2016 and their possible maternal and neonatal factors associated. Methods Cross-sectional retrospective observational study with a population of 7,217 pregnant women who had a live birth in the CMRC. The prevalence of total and term (≥37 gestation weeks "GW") LBW were estimated from the weight of the newborn. Risk factors associated with LBW were estimated through a logistic regression model. Modeled variables were weight, maternal age, prenatal control, mother´s education level, area of residence and multiplicity of pregnancy. Statistical significance was defined in 5% and 10%. Results The prevalence of total and term LBW in the CMRC were 11.6% (838 cases out of 7,217) and 4.2% (259 out of 6,203) respectively. The risk of LBW is 16.6% (p=0.061) and 37.0% (p=0.044) lower in mothers between 20 and 34 years and 35 years or more respectively, than in mothers under 20. A child born at term represents a lower risk (β = 0.03, p=0.000) of LBW than a pre-term (<37GW). Mothers with controlled pregnancy (4 or more prenatal visits) have a lower risk (β =18.6%, p=0.042) to have a baby with LBW than mothers who are not controlled. Expecting two or more children in the same pregnancy increases the risk (β=3.3, p=0.000) of LBW compared to expecting a single child. Living in urban areas decreases the risk of LBW by 21% (p = 0.057) compared to living in rural areas. Conclusions We found significant low birth weight in newborns in the CMRC. The prevalence of total LBW (11.6%) was above figures for Colombia (9.0%) and Cartagena (8.9%) in 2015. Controlling the risk factors associated to LBW could be favorable for its reduction.
