Assessment of diet and physical activity and their determinants still remains a demanding task, especially when the objective is to evaluate the efficacy of lifestyle interventions. In the context of the Feel4Diabetes study (a European community based intervention study in families with school aged children and at high risk of developing diabetes), we aimed to develop questionnaires for the assessment of food-frequency and eating behaviors, and physical activity and sedentary behaviors in both parents and school-aged children and a questionnaire for overall family’s energy balance-related behaviors. Questionnaires were developed to be used in 6 countries under standardized harmonization procedures and included questions regarding not only food intake and physical activity, but also questions of their determinants. A reliability study was conducted in 191 pairs of parents and their children (N = 191). Parents completed the questionnaires on two occasions, within a 1–2 week interval. Reliability was tested by the intra-class correlation coefficients (ICC) of test-retest. Most of the questions in all questionnaires had excellent reliability, assessed as an ICC of > 0.810. Mean ICCs for food-frequency and eating behaviors questionnaires were 0.838 and 0.787, and for physical activity and sedentary behaviors questionnaires were 0.734 and 0.793, in adults and children respectively. Mean ICC for overall family’s energy balance-related behaviors and their determinants was 0.659. The developed questionnaires showed acceptable reliability and may be valuable tools in the assessment of children’s and parents’ behaviors related to diet, physical activity, sedentary behavior and overall energy balance in school- and community-based interventions.

在欧洲多个国家中评估饮食和身体活动行为的问卷的开发和可靠性Feel4Diabetes研究

饮食和身体活动及其决定因素的评估仍然是一项艰巨的任务，尤其是当目标是评估生活方式干预的有效性时。在Feel4Diabetes研究（基于欧洲社区的学龄儿童和罹患糖尿病高风险家庭的干预研究）的背景下，我们旨在开发用于评估食物频率和饮食行为，身体活动和久坐的问卷调查表父母和学龄儿童的行为以及家庭整体能量平衡相关行为的问卷。制定了调查表，以在6个国家/地区采用标准化的协调程序，不仅包括食物摄入和身体活动的问题，还包括决定因素的问题。在191对父母及其子女中进行了可靠性研究（N = 191）。父母在1-2周的间隔内两次完成了问卷。可靠性通过测试-再测试的类内相关系数（ICC）进行测试。所有问卷中的大多数问题都具有极好的可靠性，ICC≥0.810。成年人和儿童的饮食频率和进食行为问卷的平均ICC分别为0.838和0.787，体育活动和久坐行为问卷的ICC分别为0.734和0.793。整个家庭与能量平衡相关的行为及其决定因素的平均ICC为0.659。编制的调查表显示出可接受的可靠性，可能是评估儿童和父母与饮食，身体活动，
