Augmented BMI and waist to height ratio as screening tools for overweight and obesity among school going children aged 5 to 15 years
Keywords:Anthropometry, Augmented BMI, Metabolic syndrome, Waist to height ratio
Background: Worldwide raising trend in obesity among children is causing serious public health concerns and in developing countries it is threatening the viability of basic health care delivery. The objective of this study was to screen for overweight and obesity among school going children using the established methods as well as the newer screening tools and to compare the efficacy of the various screening tools
Methods: Prospective cross sectional study was conducted various government and non-government schools within city limits. And participants involves 1000 children in the age group of 5 to 15 years who met the predefined criteria were selected by purposive sampling.
Results: Using BMI as a screening tool, 6.3% were identified as overweight and 5.8% as obese. Using Waist circumference alone, 5.2% were identified as overweight and 4.5% as obese. 13.8% and 5% were identified as overweight and obese respectively by waist circumference to height ratio. Using augmented BMI, 14.7% were identified as overweight and 4.3% as obese.
Conclusions: Using WHTR and Augmented BMI, larger percentage of children were identified as overweight while the percentage of children identified as obese remained similar to using BMI or Waist circumference alone.
