Waist circumference (WC) and waist-to-height ratio (WHtR) begin to gain attention as measures of adiposity and as important cardiometabolic disease risk factors also among children. Still, little research has been done on behavioral determinants of WC and WHtR in children. The purpose of this study was to examine associations between health behaviors, WC and WHtR in children.
The study was a cross-sectional study conducted in Swedish-speaking schools in Helsinki region in 2006. In all, 1146 children were recruited, from which 55 % took part in the study. A total of 604 9-11-year-old children (312 girls, 292 boys) were measured by research staff and completed a study questionnaire on their health behaviors, including breakfast intake, TV viewing, sleep duration and physical activity, and a 16-item food frequency questionnaire. Covariance analysis was used as the statistical analysis method.
When controlling for other health behaviors, for example, irregular breakfast (B-coefficient 2.49 CI, 0.64-4.34; P<0.01), TV viewing (B-coefficient 0.89 CI, 0.17-1.61; P<0.05), a TV in child's room (B-coefficient 2.30 CI, 0.73-3.86; P<0.01) and physical inactivity during school breaks (B-coefficient 0.78 CI, 0.19-1.37; P<0.01) were associated with larger WC. Results were similar with WHtR.
Many health behaviors were related to children's WC and WHtR. Determinants were associated to both WC and WHtR similarly.
腰围（WC）和腰高比（WHtR）作为肥胖的衡量标准，并作为重要的心血管代谢疾病风险因素，在儿童中也开始受到关注。尽管如此，针对儿童 WC 和 WHtR 的行为决定因素的研究仍然很少。本研究旨在探讨儿童健康行为与 WC 和 WHtR 之间的关系。
该研究是 2006 年在赫尔辛基地区的瑞典语学校进行的横断面研究。共有 1146 名儿童参加，其中 55%的儿童参加了研究。共有 604 名 9-11 岁儿童（312 名女孩，292 名男孩）由研究人员进行测量，并完成了一份关于其健康行为的研究问卷，包括早餐摄入、看电视、睡眠时间和身体活动，以及一份 16 项食物频率问卷。协方差分析被用作统计分析方法。
在控制其他健康行为（例如不规则的早餐（B 系数 2.49，CI：0.64-4.34；P<0.01）、看电视（B 系数 0.89，CI：0.17-1.61；P<0.05）、孩子房间里的电视（B 系数 2.30，CI：0.73-3.86；P<0.01）和课间不活跃（B 系数 0.78，CI：0.19-1.37；P<0.01））后，WC 更大。WHtR 也有类似的结果。
许多健康行为与儿童的 WC 和 WHtR 相关。决定因素与 WC 和 WHtR 均相关。
