Challenges of Accurately Measuring and Using BMI and Other Indicators of Obesity in Children

Abstract: BMI is an important indicator of overweight and obesity in childhood and adolescence. When measurements are taken carefully and compared with appropriate growth charts and recommended cutoffs, BMI provides an excellent indicator of overweight and obesity that is sufficient for most clinical, screening, and surveillance purposes. Accurate measurements of height and weight require that adequate attention be given to data collection and management. Choosing appropriate equipment and measurement protocols and prov… Show more

“…Second, our analyses were based on indirect measures of adiposity (BMI), although it has been found to be sufficiently accurate and widely used in epidemiological studies. 41 Third, the BP was measured on 1 occasion only. When possible, BP should be measured in different days to establish the true level of BP.…”

“…Our decision to use change in BMI rather than BMI z-score as the primary outcome measure was based on several factors. BMI is a popular indicator of weight status for children 20,21 and has been suggested to explain more variance in body weight than BMI z-scores among children aged 10 years and younger. 21 Furthermore, research suggests that change in BMI is more powerful and interpretable than change in BMI z-scores when assessing longitudinal changes in BMI.…”

“…Es preciso mencionar que en los niños menores de cinco años, tanto en el caso peso para la talla (P/T) como para el IMC, las 2z son el punto de corte que la OMS denomina sobrepeso (27,28) , estimación que corresponde a un percentil mayor que el 95 (1,64z); el cual ha sido llamado obesidad por otras organizaciones incluyendo el Centro de Prevención y Control de Enfermedades (CDC) (29) . Para efectos de análisis del presente artículo, usaremos el punto de corte propuesto por la OMS considerando en una sola categoría, de acuerdo con lo empleado con mayor frecuencia en la literatura nacional (la prevalencia nacional usando 3z es 3,4% en el MONIN), así como por el hecho de que la obesidad es una condición clínica relacionada con el exceso de grasa corporal, por lo que la medición de indicadores antropométricos sería solo una estimación (27) .…”
