摘要

In reply to the comment of Kersting et al. [1], there is a need to mention that there are multiple health behaviors, which may relate to health-related quality of life. Nudelman and Shiloh attempted to cluster these behaviors and created a taxonomy consisting of 66 health behaviors [2]. In a network analytic approach, they screened all those behaviors for interrelatedness and centrality [3] and found eating behavior to be one of the most central ones. This, in turn, may substantiate the assumption determined by the authors of the respective comment that dietary behavior may be as important in the prediction of HRQoL as physical activity and screen time. A recent review and meta-analysis of Wu and colleagues [4] support this assumption, as the authors found that dietary behavior was indeed associated with health-related quality of life in children and adolescents.
