Relationship between environment and growth for Mopan children in Belize

Area of Science:

• Pediatric Nutrition
• Human Growth and Development
• Socioeconomic Determinants of Health

Background:

• Child growth is influenced by environmental and socioeconomic factors, particularly in impoverished communities.
• Understanding growth patterns is crucial for assessing public health and resource allocation.
• Mopan Maya children in Belize face unique challenges related to poverty and resource access.

Purpose of the Study:

• To evaluate the growth status (stature, weight, BMI, etc.) of Mopan Maya children aged 9-14.
• To identify associations between child growth and household/environmental factors linked to poverty.
• To examine child growth in the context of national resource distribution.

Main Methods:

• One-way ANOVA for age-related growth differences.
• T-tests to compare growth parameters between genders.
• Correlation and regression analyses for socioeconomic and demographic factors.

Main Results:

• Significant age-related differences in growth z-scores were observed.
• Boys had lower weight, arm circumference, and muscle mass z-scores but higher fat z-scores than girls.
• Household socioeconomic status, birth order, home environment, and gender significantly explained growth variations.

Conclusions:

• San Antonio children exhibit growth faltering compared to US reference data, likely due to chronic undernutrition.
• Inadequate infrastructure and limited resource access in Toledo District contribute to suboptimal growth.
• Household socioeconomic and environmental factors are critical determinants of Mopan Maya child growth.
