Obesity and metabolic risks in children.

Area of Science:

• Pediatric Health
• Public Health
• Metabolic Disorders

Background:

• Assessing the prevalence of overweight, obesity, abdominal obesity, hypertension, and dyslipidemia in Mexican school children.
• Investigating the relationship between overweight/obesity and other metabolic risk factors in this population.

Purpose of the Study:

• To establish the prevalence of key metabolic risk factors in Mexican school-age children.
• To determine the association between overweight and obesity with other cardiovascular risk factors.

Main Methods:

• Cross-sectional survey of 1819 children (6-13 years) from six elementary schools in Mexico City.
• Data collection included gender, age, weight, height, waist circumference, blood pressure, glucose, and triglyceride levels.
• Analysis involved calculating percentiles against American standards for BMI, waist circumference, and blood pressure.

Main Results:

• Mexican children were shorter and heavier than American references (BMI and waist circumference percentiles >50, height percentiles <50).
• Prevalence rates: overweight (22.3-23.6%), obesity (21.2-28%), abdominal obesity (11.7-22.1%), high triglycerides (11.3-15.4%), high blood pressure (4.8-5.8%).
• Overweight, obesity, and abdominal obesity were significantly associated with higher blood pressure and triglyceride levels (OR>1.0, p<0.05).

Conclusions:

• Mexican school-age children exhibit distinct anthropometric differences compared to American standards, being shorter and heavier.
• The prevalence of metabolic risks in this cohort is comparable to that observed in American adolescents.
• Findings highlight the need for targeted public health interventions for childhood obesity and metabolic health in Mexico City.
