The prevalence of cardiovascular risk factors in obese children

Area of Science:

• Pediatrics
• Public Health
• Cardiology

Background:

• Childhood obesity is a significant public health concern in Ireland.
• Obesity in children is associated with metabolic diseases and increased cardiovascular disease risk.
• Early identification and management of cardiovascular risk factors in obese children are crucial.

Purpose of the Study:

• To determine the prevalence of cardiovascular risk factors in a cohort of obese Irish children.
• To investigate the relationship between physical activity levels and cardiovascular risk factors in this population.
• To highlight the need for targeted interventions in pediatric obesity management.

Main Methods:

• Cross-sectional study of 59 obese children (21 prepubertal, 38 pubertal/post-pubertal) attending a weight management clinic.
• Assessment of physical activity levels using pedometers and self-report questionnaires.
• Metabolic profiling and measurement of BMI, Waist Circumference, and Body Fat percentage.

Main Results:

• High prevalence of obesity indicated by mean z scores for BMI (+3.29), Waist Circumference (+3.98), and Body Fat % (+2.75).
• 43% of prepubertal and 68% of pubertal/post-pubertal obese children had at least one additional cardiovascular risk factor.
• Higher moderate-to-vigorous physical activity levels correlated with a lower incidence of cardiovascular risk factors.

Conclusions:

• Obese children in Ireland, both prepubertal and pubertal/post-pubertal, exhibit a significant prevalence of cardiovascular risk factors.
• Physical activity is a key modifiable factor in mitigating cardiovascular risk in obese pediatric populations.
• Urgent public health strategies are needed to address childhood obesity and its associated health complications in Ireland.
