Home-schooled children are thinner, leaner, and report better diets relative to traditionally schooled children.

To examine and compare the relationships among diet, physical activity, and adiposity between home-schooled children (HSC) and traditionally schooled children (TSC).
DESIGN AND METHODS
Subjects were HSC (n=47) and TSC (n=48) aged 7-12 years old. Dietary intakes were determined via two 24-h recalls and physical activity was assessed with 7 days of accelerometry. Fat mass (FM), trunk fat, and percent body fat (%BF) were measured by dual-energy X-ray absorptiometry (DXA).
Relative to HSC, TSC demonstrated significantly higher BMI percentiles, FM, trunk fat, and %BF; consumed 120 total kilocalories more per day; and reported increased intakes of trans fats, total sugar, added sugars, calcium, and lower intakes of fiber, fruits, and vegetables (P<0.05). At lunch, TSC consumed significantly more calories, sugar, sodium, potassium, and calcium compared to HSC (P<0.05). Physical activity did not differ between groups. Traditional schooling was associated with increased consumption of trans fat, sugar, calcium (P<0.05); lower intakes of fiber, and fruits and vegetables (P<0.05); and higher FM, %BF, and trunk fat (P<0.01), after adjustment for covariates.
These data suggest HSC may consume diets that differ in energy and nutrient density relative to TSC, potentially contributing to differences in weight and adiposity.
