Insights
Low birth weight (LBW) affects neonatal health, with maternal anemia, inadequate antenatal care, and premature delivery being key risk factors. Addressing maternal health is crucial to reduce LBW prevalence and improve infant outcomes.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Health
- Public Health
Background:
- Low birth weight (LBW) is a significant determinant of neonatal morbidity and mortality, with global prevalence at nearly 15%.
- India faces a substantial LBW burden, ranging from 16-30%, influenced by maternal factors.
- Understanding these influencing parameters is critical for targeted interventions.
Purpose of the Study:
- To determine the key influencing parameters for the occurrence of low birth weight (LBW) in a tertiary care setting.
- To identify independent risk factors associated with LBW.
- To explore the association between LBW and neonatal complications.
Main Methods:
- A retrospective observational study was conducted over 24 months.
- Data were collected from 1216 live newborns delivered at a tertiary care center.
- Information was recorded using a predesigned questionnaire from institutional medical records.
Main Results:
- The prevalence of LBW was 27.55% (335/1216), with a 1:3 ratio of LBW to normal birth weight (NBW) babies.
- Significant risk factors for LBW included maternal anemia (59.39%), young maternal age (30.39%), parity ≥ 3 (35.71%), fewer than 3 antenatal care (ANC) visits (56.88%), and premature delivery (71.57%).
- Maternal anemia (OR 4.7), inadequate ANC (OR 2.2), and prematurity (OR 7.6) were independent risk factors. LBW was associated with neonatal complications (OR 1.6).
Conclusions:
- Inadequate antenatal care, maternal anemia, and illnesses leading to premature delivery are critical determinants of LBW.
- These factors contribute significantly to neonatal mortality and morbidity.
- Improving maternal health status is essential for reducing the burden of LBW.
Objectives:
LBW is the strong determinant of neonatal morbidity and mortality with a global prevalence of nearly 15%. India's prevalence, though not yet established, ranges from 16-30% and influenced by maternal nutritional status, antenatal care and associated maternal morbidity. Hence, the study was aimed to determine the influencing parameters for occurrence of LBW.
Study Design:
A retrospective observational study conducted for all live newborns delivered in a tertiary care centre during the study period of twenty four months.
Methods:
Data from institutional medical record section was recorded on predesigned questionnaire from a total of 1216 newborns.
Results:
The percentage of LBW was found to be 27.55% (335/1216) with a proportion of LBW to NBW babies was approximately 1:3. The occurrence of LBW was significantly higher in babies of anemic mothers (59.39%, P < 0.0001), young mothers (30.39%, P < 0.01), mothers with parity ≥ 3 (35.71%, P < 0.05), those with <3 ANC check-up (56.88%, P < 0.0001) and those with premature delivery (71.57%, P < 0.0001). Maternal anemia (OR 4.7, 95%CI 3.4-6.7, P < 0.001); ANC with <3 visits (OR 2.2, 95%CI 1.4-3.4, P < 0.01) and prematurity (OR 7.6, 95%CI 5.1-11.2, P < 0.0001) were considered as independent risk factor for LBW. Significant association of neonatal complications was found with LBW babies (OR 1.6, 95%CI 1.1-2.5, P < 0.05).
Conclusions:
Inadequate antenatal care, maternal anemia and other maternal illness causing premature delivery are considered critical determinants for LBW and thus associated with high neonatal mortality and morbidity. Continued focus for improving the overall maternal health status would lead to lowering burden of LBW.
