To evaluate the relationship between children's lifestyles and health-related quality of life and to explore whether this relationship varies among children from different world regions.
This study used cross-sectional data from the International Study of Childhood Obesity, Lifestyle and the Environment. Children (9-11 years) were recruited from sites in 12 nations (n = 5759). Clustering input variables were 24-hour accelerometry and self-reported diet and screen time. Health-related quality of life was self-reported with KIDSCREEN-10. Cluster analyses (using compositional analysis techniques) were performed on a site-wise basis. Lifestyle behavior cluster characteristics were compared between sites. The relationship between cluster membership and health-related quality of life was assessed with the use of linear models.
Lifestyle behavior clusters were similar across the 12 sites, with clusters commonly characterized by (1) high physical activity (actives); (2) high sedentary behavior (sitters); (3) high screen time/unhealthy eating pattern (junk-food screenies); and (4) low screen time/healthy eating pattern and moderate physical activity/sedentary behavior (all-rounders). Health-related quality of life was greatest in the all-rounders cluster.
Children from different world regions clustered into groups of similar lifestyle behaviors. Cluster membership was related to differing health-related quality of life, with children from the all-rounders cluster consistently reporting greatest health-related quality of life at sites around the world. Findings support the importance of a healthy combination of lifestyle behaviors in childhood: low screen time, healthy eating pattern, and balanced daily activity behaviors (physical activity and sedentary behavior).

评估儿童生活方式与健康相关生活质量之间的关系，并探讨这种关系在来自不同世界区域的儿童中是否存在差异。
本研究使用了来自儿童肥胖、生活方式与环境国际研究的横断面数据。从12个国家的研究点招募了9至11岁的儿童（n = 5759）。聚类输入变量为24小时加速度计测量结果以及自我报告的饮食和屏幕使用时间。健康相关生活质量通过儿童生活质量量表-10（KIDSCREEN-10）进行自我报告。在每个研究点分别进行聚类分析（使用成分分析技术）。比较各研究点之间的生活方式行为聚类特征。使用线性模型评估聚类成员与健康相关生活质量之间的关系。
12个研究点的生活方式行为聚类相似，聚类通常具有以下特征：（1）高身体活动水平（活跃型）；（2）高久坐行为（久坐型）；（3）高屏幕使用时间/不健康饮食模式（垃圾食品屏幕族）；以及（4）低屏幕使用时间/健康饮食模式且身体活动/久坐行为适度（全面发展型）。全面发展型聚类中的儿童健康相关生活质量最高。
来自不同世界区域的儿童聚集成生活方式行为相似的群体。聚类成员与不同的健康相关生活质量相关，全面发展型聚类中的儿童在世界各地的研究点始终报告最高的健康相关生活质量。研究结果支持童年时期生活方式行为健康组合的重要性：低屏幕使用时间、健康饮食模式以及平衡的日常活动行为（身体活动和久坐行为）。
