Sedentary behaviors (SB) are associated with health indicators; however, there are currently very few studies that have examined these associations, especially in conjunction with psychological factors, in children. The current study examined the independent relationship between objectively assessed SB, and indicators of obesity and psychological well-being, among Japanese children.
A total of 967 elementary-school children completed a cross-sectional survey. SB was measured with accelerometers for 7 consecutive days. Psychological well-being data (eg, anxiety and behavior problems) were collected via a self-report questionnaire. To determine the relationship of SB with degree of obesity and psychological well-being, linear regression analyses were conducted to relate the indicators of obesity and psychological well-being on SB, adjusted by gender, grade, percentage of moderate-to-vigorous physical activity per day, duration spent wearing the accelerometer, and degree of obesity.
SB was significantly related to behavioral/emotional problems (β = .280, P = .010, R = .015). There was a statistically significant relationship between SB and anxiety (β = .206, P = .059, R = .007). No significant association with degree of obesity was found.
Excess SB relates higher levels of behavioral/emotional problems and anxiety. These results can inspire the development of interventions that promote well-being and enhance psychological health, by focusing on SB in Japanese children.
久坐行为（SB）与健康指标相关；然而，目前很少有研究探讨这些关联，尤其是在儿童中结合心理因素进行的研究。本研究调查了日本儿童中客观评估的久坐行为与肥胖指标及心理健康之间的独立关系。
共有967名小学生完成了一项横断面调查。使用加速度计连续7天测量久坐行为。通过自我报告问卷收集心理健康数据（如焦虑和行为问题）。为了确定久坐行为与肥胖程度和心理健康的关系，进行了线性回归分析，以关联久坐行为的肥胖指标和心理健康指标，并根据性别、年级、每天中度至剧烈身体活动的百分比、佩戴加速度计的时长以及肥胖程度进行调整。
久坐行为与行为/情绪问题显著相关（β = 0.280，P = 0.010，R = 0.015）。久坐行为与焦虑之间存在统计学上的显著关系（β = 0.20 , P = 0.059，R = 0.007）。未发现与肥胖程度有显著关联。
久坐行为过多与更高水平的行为/情绪问题和焦虑相关。这些结果可以启发通过关注日本儿童的久坐行为来开发促进幸福感和增强心理健康的干预措施。
