Log-log regression analysis was used to estimate the power with which to raise height to control for the effect on weight and waist circumference.ResultsBMI correlated with height in girls (r=0.513, p=0.003) and boys (r=0.402, p=0.027). We have previously shown, in a group of Welsh schoolchildren, that BMI does not fully adjust for the effect of height during puberty and that waist to-height ratio (WaHtR) is more reliable (Lewitt et al., Ann Hum Biol 39:440, 2012).AimTo determine the relationship between height and weight, and height and waist circumference in overweight children participating in a family-based intervention programme (MEND) in Scotland.SubjectsGirls (n=32) and boys (n=30) aged 7-13 years and > 91st centile for BMI, adjusted for age and sex. Most programmes follow the weight/height2 (BMI). During the 10 week MEND intervention WaHtR decreased by 3.6% in girls and 3.5% in boys while BMI changed 2.9 and 2.5%, respectively (both p<0.001).ĬonclusionWaHtR is a more reliable than BMI in overweight children aged 7-13 years, and should be used to track responses to lifestyle interventions in this age group.Ībstract = "BackgroundFamily-based intervention programmes are effective for overweight children. There was no relationship between WaHtR and height in girls (r=-0.087,p=0.635) or boys (r=-0.005, p=0.977). Log-log regression analysis indicated that height needed to be raised to the power 2.9 and 2.7, respectively,to control for its effect on weight.
