Abstract
Background: Low birth weight (LBW) is a major global public health problem and a leading cause of neonatal mortality, as well as a significant risk factor for infant and under-five morbidity and mortality.
Objective: The study aimed to determine the association between maternal lifestyle factors and low birth weight, and to investigate the relationship between maternal hemoglobin levels and LBW infants.
Methods: A total of 518 samples were included in the study, comprising 259 cases and 259 controls. Data were collected using a standard questionnaire administered through interviews and medical record reviews. The questionnaire covered maternal lifestyle factors and hemoglobin levels. Logistic regression was employed to analyze the associations between maternal lifestyle risk factors, hemoglobin levels, and low birth weight. Descriptive statistics were calculated for each variable, and statistical relationships were assessed using IBM SPSS version 25, with a significance level set at 0.05.
Results: The study found that maternal hemoglobin levels (OR=0.742, 95% CI: 0.644-0.855, p<0.001) and gestational age (OR=0.776, 95% CI: 0.696-0.866, p<0.001) were inversely associated with low birth weight. Conversely, previous pregnancies (OR=5.043, 95% CI: 2.004-12.689, p=0.001 for one previous pregnancy), low maternal income (OR=7.156, 95% CI: 2.369-21.617, p<0.001), specific occupations (OR=2.354, 95% CI: 1.416-3.914, p=0.001), and being underweight (OR=26.829, p<0.001) were positively associated with low birth weight.
Conclusion: These findings emphasize the importance of considering various socio-economic and health factors in the prevention and management of low birth weight, with a particular focus on maternal occupational status, income, previous pregnancies, gestational age, pregnancy complications, and maternal hemoglobin levels.
