Risk Factors Of Low Birth Weight; Case-Control Study

Journal Title: JOURNAL OF CONTEMPORARY MEDICINE - Year 2017, Vol 7, Issue 2

Abstract

Aim: Low birth weight (LBW) (defined as a birth weight of less than 2500 grams) is associated with fetal and neonatal morbidity and mortality, impaired cognitive development, and the advent of chronic diseases in later life. The global incidence of LBW is around 15,5%. The aim of this study was to identify risk factors for low birthweight in the centre of Denizli province.Materials and methods: A case-control study was carried out and mothers of 295 newborns with birthweight between 1500-2499 g (cases) and 302 newborns with birthweight between 2500-4000 g (controls) were analyzed. The questionnare was applied to women using face to face technics between July,2009 and June,2010 . The questionnare included birth weight and birth lenght of newborn, the date of last pregnacy and type of last delivery, profile of mother, anthropometric measures, life styles, habits, addictions, sociodemographic and socioeconomic characteristics of mother and father of newborn. Analysis included frequency and percent distributions, means, standart deviations. In group comparisions for categorical variable, chi square test and odds ratio (OR) was used. Logistic regression model was performed for some selected risk factors. P<0.05 was considered statistically significant. Statistical Package for Social Sciences (SPSS) program, Version 10 was used for data entry and analysis. Results: When backward logistic regression model was performed for some selected factors in relation to low birth weight, there was a positive relationship between multiple pregnancy [OR(95%CI) 18.50 (8.54, 40.39)], BMI lower than 20 kg/m2 of mother before pregnancy andemployment status [OR(95%CI) 1.98 (1.23, 3.19)], weight gain of 7 kg and under during pregnanacy [OR(95%CI) 2.49 (1.56, 3.96)], a history of giving birth to low birth weight infant [OR(95%CI) 3.44 (1.69, 7.02)], first- degree and second- degree relative’s histories of giving birth to low birth weight infant [OR(95%CI) 4.28 (2.61, 6.94)], X- ray exposure in the three months before and during pregnancy [OR(95%CI) 3.35 (1.26, 8.91)], to be incomplete tetanus vaccinated [OR(95%CI) 4.83 (2.32, 10.08)], first live births [OR(95%CI) 3.43 (2.15, 5.49)], severe life experiences during pregnancy [OR(95%CI) 1.60 (1.01, 2.55)], unemployed [OR(95%CI) 1.69 (1.06, 2.70)], working in the informal labor [OR(95%CI) 2.44 (1.03, 5.82)]. Conclusion: Efforts to prevent risk factors determined in this study also reduce the incidence of LBW.
