Summary
Malnutrition negatively impacts lung function in Indian schoolchildren, reducing peak expiratory flow rate (PEFR). However, chronic malnutrition affects lung growth less than overall body growth.
Area of Science:
- Pediatric Nutrition
- Respiratory Physiology
- Public Health
Background:
- Malnutrition is a significant public health concern in developing countries, potentially affecting various physiological functions.
- Lung function development is crucial during childhood and can be influenced by nutritional status.
Purpose of the Study:
- To investigate the association between malnutrition and lung function in Indian schoolchildren.
- To differentiate the effects of acute versus chronic malnutrition on peak expiratory flow rate (PEFR).
Main Methods:
- A cross-sectional study involving 376 Indian schoolchildren aged 6-12 years.
- Nutritional status assessed using height-for-age (HFA) and weight-for-height (WFH) percentages based on Harvard standards.
- Peak expiratory flow rate (PEFR) measured using a Wright peak flow meter.
Main Results:
- Children with current malnutrition (wasted, WFH <80%) showed significantly reduced PEFR (p<0.01).
- Stunted children (HFA <90%) exhibited higher than average PEFR (p<0.05).
- After standardization for height and sex, these associations remained significant.
Conclusions:
- Current malnutrition adversely affects PEFR, likely due to impaired muscle function.
- Past or chronic malnutrition has a lesser impact on lung function growth compared to somatic growth.
- Early nutritional interventions may be crucial for optimal lung development in children.
