Importance of periodic measurements in evaluating feeding programmes
The Indian Journal of Medical Research
|February 1, 1992
Summary
Periodic measurements are crucial for assessing feeding program effectiveness due to significant individual growth variations. Longitudinal studies reveal alternating growth priorities, highlighting the need for detailed tracking in children.
Area of Science:
- Pediatrics
- Nutrition Science
- Growth Monitoring
Background:
- Evaluating the impact of feeding programs requires understanding growth dynamics.
- Significant "within-child" variation in growth increments can obscure overall program effects.
Purpose of the Study:
- To demonstrate the importance of periodic measurements in assessing feeding program impacts.
- To analyze growth patterns and correlations in children from different socio-economic backgrounds.
Main Methods:
- Longitudinal study design involving 273 children across two kindergartens (one with a feeding program, one without).
- Three sets of weight and height measurements taken over a 7-month period.
- Statistical analysis of weight and height increments, including simple and cross-correlations.
Main Results:
- Normal children showed significant weight gain, while malnourished children exhibited significant height gain.
- Overall program significance did not always translate to significance in shorter, equal time intervals.
- Weight increment in one period correlated significantly with height increment in the subsequent period, indicating alternating growth priorities.
Conclusions:
- Periodic measurements are essential for accurately evaluating feeding programs due to inherent growth variability.
- Longitudinal growth studies are vital for a comprehensive understanding of child development and program efficacy.
- Observed alternating growth priorities suggest complex physiological regulation influencing child development.
