Abstract
Objective
To examine the utility of waist-to-height ratio to identify risk of high blood pressure when compared to body mass index and waist circumference in South Indian urban school children.
Design
Secondary data analysis from a cross-sectional study.
Setting
Urban schools around Bangalore, India.
Participants
1913 children (58.1% males) aged 6-16 years with no prior history of chronic illness (PEACH study).
Methods
Height, weight, waist circumference and of blood pressure were measured. Children with blood pressure ≥90th percentile of age-, sex-, and height-adjusted standards were labelled as having high blood pressure.
Results
13.9% had a high waist-to-height ratio, 15.1% were overweight/obese and 21.7% had high waist circumference. High obesity indicators were associated with an increased risk of high blood pressure. The adjusted risk ratios (95% CI) of high systolic blood pressure with waist-to-height ratio, body mass index and waist circumference were 2.48 (1.76, 3.47), 2.59 (1.66, 4.04) and 2.38 (1.74, 3.26), respectively. Similar results were seen with high diastolic blood pressure.
Conclusion
Obesity indicators, especially waist-to-height ratio due to its ease of measurement, can be useful initial screening tools for risk of high blood pressure in urban Indian school children.
