To assess how diet quality, physical activity and body weight are related to health-related quality of life (HRQOL) among children in the Canadian province of Alberta.
In 2008, we surveyed 3421 grade 5 students and their parents from 148 randomly selected schools. Students completed the Harvard Food Frequency Questionnaire, questions on physical activities, and had their height and weight measured. The HRQOL of the students was assessed using the EQ-5D-Y. Parents completed questions on socio-economic background and children's lifestyle. We applied multilevel regression methods to examine the importance of children's diet quality, physical activity and weight status for the EQ-5D-Y Visual Analogue Scale and for the EQ-5D-Y dimensions.
The province of Alberta, Canada.
Grade 5 students.
Students with better diet quality, higher physical activity levels and normal body weights were statistically significantly more likely to report better HRQOL than students who ate less healthily, were less active or were overweight or obese.
The importance of diet quality, physical activity and body weight status for HRQOL may help justify broader implementation of school health programmes that promote healthy eating and active living, as these programmes will help reduce the burden of childhood obesity and improve quality of life.
评估加拿大艾伯塔省儿童的饮食质量、身体活动和体重与健康相关生活质量（HRQOL）之间的关系。
2008 年，我们调查了来自 148 所随机选择的学校的 3421 名五年级学生及其家长。学生完成了哈佛食物频率问卷、身体活动问题，并测量了他们的身高和体重。学生的 HRQOL 使用 EQ-5D-Y 进行评估。家长填写了关于社会经济背景和孩子生活方式的问题。我们应用多层次回归方法来检查儿童的饮食质量、身体活动和体重状况对 EQ-5D-Y 视觉模拟量表和 EQ-5D-Y 维度的重要性。
加拿大艾伯塔省。
五年级学生。
饮食质量更好、身体活动水平更高、体重正常的学生，与饮食不健康、活动较少、超重或肥胖的学生相比，报告的 HRQOL 明显更好。
饮食质量、身体活动和体重状况对 HRQOL 的重要性可能有助于证明更广泛地实施促进健康饮食和积极生活的学校健康计划是合理的，因为这些计划将有助于减少儿童肥胖的负担并提高生活质量。
