Background:

Self-rated health (SRH) is a common indicator of health-related quality of life; however, little is known about SRH in children. This study explored the associations of physical activity (PA), sedentary behavior (SED), and BMI with SRH in children at risk for obesity.

Methods:

Participants were 527 children aged 8–10 years in the Quebec Adipose and Lifestyle Investigation in Youth study (inclusion criteria: ≥ 1 parent clinically obese). PA and SED were measured by accelerometer, specific SED behaviors by self-report, and height and weight measured.

Results:

About 40% of children were overweight or obese; 48% reported lessthan- excellent health. The odds of reporting less-than-excellent health were higher among obese girls (OR 3.0, 95% CI 1.4–5.2) and boys (OR 2.7, 95% CI 1.5–6.1) versus healthy weight children. Boys not meeting PA guidelines and boys in the lowest moderate-to-vigorous PA tertile were at 2 and 6 times higher odds of less-than-excellent SRH, respectively, versus more active boys. In girls, higher computer/video time and reading time were associated with higher and lower odds of less-than-excellent SRH, respectively.

Conclusions:

Obesity is inversely associated with SRH in boys and girls, PA is positively associated with SRH in boys, and SED behaviors are associated with SRH in girls.
