Sedentary behavior, overweight and obesity: a systematic literature review on direction of causality
Year: 2016
Type: review
Study design: Systematic Review
Abstract: Background: Sedentary behavior has emerged as a new field of science, whereas it has been\nassociated with several health problems such as obesity, independent of level of physical\nactivity. However, it is unclear whether sedentary behavior is a cause or a result of\noverweight or obesity, or vice versa. To date, there is no review of prospective studies that\nsystematically examine this relationship\nObjective: To provide a systematic literature review of the existing literature of prospective\npopulations-based studies investigating the bidirectional relationship between sedentary\nbehavior and overweight and obesity among non-patient children to middle-aged adults, and\nto consider the directions of this causality\nMethod: This systematic literature review was conducted according to the PRISMA\nguideline, and searches were performed in four different databases; PsycINFO, EMBASE,\nPubMED and Web of Science, with search terms covering sedentary behavior and overweight\nand obesity.\nResults: Out of 23,452 articles, 161 articles were assessed for eligibility, and 10 studies were\nincluded in the final sample. Most of the studies included children ≤11 years old at baseline\n(n=4) or adults (n=4). Six studies use self-reported sedentary behavior, while the remaining\nfour studies used objective measurements. Whether baseline weight was associated with\nchange in sedentary behavior over time, four studies found no association, while one study\nfound an unfavorable association in second half of the study, and five studies found an\nadverse association. Whether baseline sedentary behavior was associated with weight gain\nover time, seven studies found no association, while one study found mixed associations\n(between various exposure- and outcome variables), and two studies found an adverse\nassociation.\nConclusion: Current evidence suggests that baseline weight predicts later sedentary\nbehavior, and that the evidence regarding a reverse- or bidirectional relationship to date is not\nof sufficient quality to determined such relationship. Future well-conducted prospective\nstudies are therefore warranted to increase knowledge in this field as well as to enhance\nheath-promoting strategies.
