An Ecological Approach to Obesity in Mexican American Children

Area of Science:

• Pediatric Health
• Nutritional Epidemiology
• Public Health

Background:

• Childhood obesity is a growing public health concern, particularly in minority populations.
• Identifying specific risk factors in Mexican American children is crucial for targeted interventions.
• The Ecological Model of Growth provides a framework for understanding multifaceted influences on child development.

Purpose of the Study:

• To explore risk factors associated with obesity in Mexican American children.
• To compare risk factors between obese and normal-weight Mexican American children.
• To inform evidence-based practices for nurses in reducing obesity-related behaviors.

Main Methods:

• Cross-sectional descriptive study design comparing obese and normal-weight Mexican American children.
• Data collected from 55 mother-child dyads in South Texas using anthropometrics, dietary intake, home environment, maternal stress, and acculturation measures.
• Statistical analyses included independent sample t tests, chi-square tests, Fisher exact tests, and hierarchical logistic regression.

Main Results:

• Childhood obesity positively correlated with children's age and maternal body mass index (BMI).
• Significant differences observed in prolonged bottle feeding, outdoor play duration, and fruit drink consumption between weight groups.
• Host and agent factors identified as key differentiators between normal-weight and obese children.

Conclusions:

• Maternal BMI and child's age are significant predictors of childhood obesity.
• Dietary habits (fruit drinks) and lifestyle factors (bottle feeding, outdoor play) play a critical role.
• Involving family in nutrition, childcare, and physical activities can mitigate obesity risks.
