Can School Feeding Programs Reduce Malnutrition in Rural China?

Area of Science:

• Public Health
• Nutrition Science
• Pediatrics

Background:

• Childhood malnutrition is prevalent in China's poor rural communities.
• China initiated a nationwide school-feeding program (SFP) in 2012 to combat this issue.
• This study assessed malnutrition rates before and after SFP implementation.

Purpose of the Study:

• To evaluate the effectiveness of China's nationwide school-feeding program (SFP) in reducing childhood malnutrition.
• To identify factors influencing malnutrition trends post-SFP implementation.

Main Methods:

• Analysis of data from two cross-sectional surveys in 100 rural primary schools in northwestern China.
• Utilized ordinary least squares regression and propensity score matching.
• Measured anemia rates, hemoglobin levels, BMI, and height-for-age Z scores in fourth and fifth graders.

Main Results:

• Malnutrition rates among students remained unchanged three years after SFP implementation.
• The SFP showed no significant impact on anemia rates or BMI.
• A notable increase in students with below-normal height-for-age Z scores was observed.

Conclusions:

• China's SFP, despite significant investment, failed to decrease childhood malnutrition prevalence.
• The program's meals provided insufficient micronutrients, falling short of national recommendations.
• Enhanced funding and human resources are crucial for improving the SFP's efficacy.
