Table 3 Energy balance, food intake and food choices in the setting of acute social stress by randomization group and weight category

From: Impact of physical activity on energy balance, food intake and choice in normal weight and obese children in the setting of acute social stress: a randomized controlled trial

  1. *p < 0.05; **p < 0.01; ***p < 0.001, § p = 0.058.
  2. LD = low density, HD = high density. LD salty food included bread, cherry tomatoes, rice cakes; HD salty food salami, crisps, peanuts; LD sweet food banana, apple and orange; HD sweet food milk chocolate, biscuits, gummy bears.
  3. The differences (95% confidence intervals) between randomization groups (children in the physical vs. the sedentary activity) or weight categories (overweight/obese vs. normal weight children) are adjusted for age, gender, parental socioeconomic status and migrant status and for weight category and randomization group, respectively.
