Effects of a Multidisciplinary Lifestyle Intervention for Obesity on Mental and Physical Components of Quality of Life: The Mediatory Role of Depression

Abstract

The current study investigates the effects of a multidisciplinary lifestyle intervention for obesity on Health Related Quality of Life (HRQoL). In this study, 92 adults with obesity were weighed and completed the Short Form Health Survey (SF-36) and the Center for Epidemiologic Studies Depression Scale (CES-D) at the baseline and at the end of a 3-month intervention. Repeated measures analysis of variance (ANOVA), a series of hierarchical regressions, and the statistical mediation analysis of Baron and Kenny were conducted. (a) Over 3 months, changes in weight and the mental and physical scales of the SF-36 and depression were all significant. (b) The results indicate a significant mediation of changes in depression scores for the association between weight loss and enhancement on the General Health scale of the SF-36. Improvements to HRQoL from a multidisciplinary lifestyle intervention seem to affect both the physical and mental components of the SF-36 score and to reduce depression, contributing to enhanced self-perceptions of well-being.

Quality of Life and Mental Health in Older Adults with Obesity and Frailty: Associations with a Weight Loss Intervention

“…Although vitality (SF-36) is a domain for the mental health composite QOL, it is also recognized as an important factor for physical QOL (33). These QOL improvements are consistent with studies showing QOL benefits derived from weight loss interventions in obese middle-aged and older individuals (8, 34). Given that our sample of obese older adults had impaired physical function at baseline and that weight loss improves physical function, it is not surprising that the participants experienced significant improvements in their physical QOL.…”

Impact of lifestyle interventions on depressive symptoms in individuals at-risk of, or with, type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled trials

“…However, lifestyle modification is more challenging among patients with diabetes who have psychiatric comorbidities, such as depression [64,65]. Interdisciplinary interventions focused on behavioral change are being utilized effectively to control depression symptoms, improve quality of life, and enhance self-care by maintaining a healthy lifestyle [66,67]. This systematic review assessed the impact of dietary and lifestyle interventions on depression scores in individuals at risk of or diagnosed with T2DM.…”
