Low birth weight (LBW) is a well-known contributing factor to neonatal health, emphasizing the importance of maternal health and socio-economic conditions. The birth weight of a newborn is a major public health problem, which is more common in low-middle-income countries (LMICs).
The objective of this study is to assess the association of different socio-economic and maternal factors with LBW babies in Lahore.
This case-control study was carried out at the Obstetrics and Gynecological Department in Mayo Hospital, Lahore, Pakistan from September 25, 2023 to December 31, 2023. A total of 186 mothers who delivered in the maternity ward, categorized into two groups (93 cases and 93 controls), were included and data was collected with the help of a self-administered structured tool. A chi-square test was used to identify maternal risk factors significant for LBW babies. The strength of association between maternal risk factors and LBW babies was presented using the odds ratio (OR) with the respective 95% confidence interval (CI).
The study revealed that maternal anemia [OR: 3.378, 95% CI: 1.568, 7.275] and inadequate nutritional status [OR: 1.031, 95% CI: 0.014, 0.071] were more likely to cause delivery of LBW babies. Regarding socio-demographic factors, household income < 25000 [OR: 5.185, 95% CI: 2.770, 9.707] and illiterate mothers [OR: 3.325, 95% CI: 1.820, 6.074] were associated with increased likelihood of LBW babies. Maternal age < 20 had a strong association [OR: 10.920, 95% CI: 2.455,48.575] with delivery of LBW children.
