Factors associated with the evolution of weight of children in a supplementary feeding program

Area of Science:

• Public Health Nutrition
• Pediatrics
• Socioeconomic Determinants of Health

Background:

• Childhood malnutrition remains a significant public health concern, particularly in low-income populations.
• Understanding factors influencing nutritional status is crucial for effective public health policies and interventions.
• Supplementary feeding programs (SFPs) aim to improve nutritional outcomes for vulnerable children.

Purpose of the Study:

• To investigate sociodemographic and biological factors associated with children aged 6-23 months improving their weight-for-age status within an SFP.
• To identify predictors of maintaining or exiting low weight-for-age status during nutritional intervention.
• To inform strategies for enhancing the effectiveness of SFPs.

Main Methods:

• A cohort study involving 327 low-income children aged six months at SFP entry.
• Data collected on maternal characteristics (marital status, schooling, age, work) and child characteristics (weaning status, gender, birth weight, age at weighing).
• Multiple multilevel logistic regression analysis was employed to model the dependent variable: maintained low weight-for-age.

Main Results:

• Higher age at weighing (OR=1.20) and higher birth weight (OR=1.0011) were positively associated with improved weight-for-age.
• Being weaned at program entry was negatively associated with maintaining low weight-for-age (OR=0.20), indicating a protective effect.
• The study identified key factors influencing children's nutritional status within the SFP.

Conclusions:

• Promoting adequate birth weight and breastfeeding are essential foundational strategies.
• Timely and appropriate introduction of complementary feeding is critical for optimizing weight gain in early childhood.
• These findings support targeted interventions to maximize the benefits of SFPs for low-income children.
