The purpose of this study was to examine the relationships among waist-to-height ratio (WHtR), aerobic fitness, and cardio-metabolic risk factors in Hispanic children from low-income U.S. schools.
Participants were 198 Hispanic children from low-income schools (Mean age = 10.3 ± 0.5 years; 119 girls, 79 boys). Waist circumference, height, and cardio-metabolic blood markers were collected in a fasted state. Estimated VO2 Peak scores were also collected. Multilevel generalized mixed effects models were employed to examine the independent effect of WHtR and aerobic fitness classification on a child meeting recommended levels for each cardio-metabolic blood marker.
A child having a WHtR < 0.5 related to meeting recommended levels for HDL cholesterol (OR = 3.25, p < .01), triglycerides (OR = 2.94, p < .01), glucose (OR = 3.42, p < .01), and related to a lower continuous Mean Arterial Pressure (MAP) score (β = −8.5 mmHg, p < .01). Aerobic fitness classification only independently related to meeting recommended levels for HDL cholesterol (OR = 2.94, p = .010).
Having a WHtR < 0.5 independently associated with favorable cardio-metabolic blood markers and thus serves as an effective screening tool for cardio-metabolic risk in Hispanic children from low-income schools.
