Are there anthropometric and body composition differences between children with autism spectrum disorder and children with typical development? Analysis by age and spectrum severity in a school population.

Esteban-Figuerola et al. (2021) measured height, weight, body fat, and heart-health markers in 206 school kids. Half had autism, half were neurotypical. They split the sample into preschool (3-5 y) and school-age (6-12 y) groups.

Nurses used stadiometers, digital scales, and skin-fold calipers. The team also checked waist size and blood pressure.

Preschoolers with ASD were about 2 cm taller than peers. The difference vanished by elementary years.

School-age kids with ASD carried more fat and showed higher obesity rates. Their waist size and blood pressure were also elevated.

Coffey et al. (2021) tested fitness in the same age range and found ASD kids weaker on every Eurofit task. Patricia’s team now shows the same children also carry extra fat. Together the papers sketch a picture: lower muscle and higher fat in ASD.

Miltenberger et al. (2013) used accelerometers and saw equal moderate-to-vigorous activity between groups. That seems to clash with the higher fat found here. The key is measurement: G counted minutes of hard movement, while Patricia counted body fat. A child can hit movement targets yet still over-eat, so both findings can be true.

Nadon et al. (2011) found triple the mealtime problems in ASD kids. Picky eating could explain the extra calories and fat Patricia observed.

Track growth charts at every clinic visit. Flag preschoolers who shoot up in height and school-age kids whose BMI or waist creeps up. Pair your behavioral plan with nutrition guidance and fun strength games to protect heart health.
