1Department of Respiratory Disease, The People's Hospital, Beijing University, Beijing 100044, China.
Insights
Children born with low birth weight exhibit reduced lung function in childhood. This study found a positive correlation between birth weight and lung function parameters, highlighting the long-term impact of birth weight on respiratory health.
Area of Science:
- Pediatric Pulmonology
- Neonatal Health Outcomes
- Respiratory Physiology
Context:
- Low birth weight (LBW) is a significant global health concern.
- Understanding the long-term respiratory consequences of LBW is crucial for early intervention.
- Gestational age and passive smoking are potential confounding factors in lung development.
Purpose:
- To investigate the association between birth weight and gestational age with lung function in later childhood.
- To compare lung function between children with LBW and healthy, normal birth weight controls.
- To identify specific lung function parameters affected by LBW.
Summary:
- A cohort study compared 35 LBW children (6-9 years) with 35 matched controls.
- Lung function tests (FVC, FEV1, etc.) revealed significantly lower values in the LBW group.
- Lung function positively correlated with birth weight but not gestational age.
Impact:
- LBW is a significant predictor of diminished lung function in childhood.
- Findings emphasize the need for monitoring respiratory health in LBW individuals.
- This research contributes to understanding the developmental origins of respiratory disease.
Objective:
To evaluate the effects of low birth weight, gestational age on lung function in later childhood.
Methods:
Height, body weight and lung function were measured in a cohort of 35 children with low birth weight (aged 6 approximately 9 y) and 35 healthy controls matched for sex and age with normal birth weight. At the same time, we inquired their gestational age and passive smoking history. The correlation analysis was used to analyze the relationship between lung function in these children and birth weight and gestational age.
Results:
FVC, FEV(1), FEV(1)% pred, V(75), V(50), V(50%) Pred, (V(25%) Pred in children with low birth weight were significantly lower than those in children with normal birth weight (P < 0.05). The lung function statistically positively correlated with birth weight (r = 0.245 approximately 0.365, P < 0.05), but not with gestational age (P > 0.05).
Conclusion:
Low birth weight was positively correlated with most lung function parameters in childhood.
