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.
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.
About 40% of children were overweight or obese; 48% reported less-than- 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.
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.
自评健康 (SRH) 是健康相关生活质量的常用指标；然而，儿童的 SRH 知之甚少。本研究探讨了身体活动 (PA)、久坐行为 (SED) 和 BMI 与肥胖风险儿童的 SRH 之间的关联。
参与者为魁北克青少年脂肪和生活方式研究中的 527 名 8-10 岁儿童（纳入标准：≥ 1 名临床肥胖的父母）。通过加速度计测量 PA 和 SED，通过自我报告测量特定的 SED 行为，并测量身高和体重。
约 40%的儿童超重或肥胖；48%报告健康状况不佳。与体重正常的儿童相比，肥胖女孩（OR 3.0，95%CI 1.4-5.2）和男孩（OR 2.7，95%CI 1.5-6.1）报告健康状况不佳的可能性更高。未达到 PA 指南的男孩和处于最低中等至剧烈 PA 三分位数的男孩，报告 SRH 不佳的可能性分别是更活跃男孩的 2 倍和 6 倍。在女孩中，较高的电脑/视频时间和阅读时间分别与较低和较高的 SRH 不佳几率相关。
肥胖与男孩和女孩的 SRH 呈负相关，PA 与男孩的 SRH 呈正相关，SED 行为与女孩的 SRH 呈负相关。
