Impact of weight change on quality of life in adults with overweight/obesity in the United States: a systematic review.

Abstract：

OBJECTIVE:To review published evidence on the impact of weight/BMI change on health-related quality of life (HRQoL) in adults from the US with overweight/obesity. METHODS:The systematic review was conducted in accordance with PRISMA guidelines. MEDLINE, Embase, EconLit, and Cochrane Library databases were reviewed using pre-defined eligibility criteria to identify relevant US studies in adults with overweight/obesity, with ≥1 year follow-up, quantified weight change, and measured HRQoL. This manuscript focuses on HRQoL derived using the Short-Form 36 (SF-36) and Impact of Weight on Quality of Life-Lite (IWQOL-Lite) instruments. RESULTS:In total, 32 of 6793 identified publications reported HRQoL according to SF-36 or IWQOL-Lite; 20 provided adequate data for inclusion in this review. Although study design and outcomes were heterogeneous, improvements in HRQoL were generally observed with weight loss. Bariatric surgery studies provided the most evidence (12 publications) and demonstrated dramatic (≥20%) weight loss and associated HRQoL improvements. Sustained weight loss was associated with maintenance of HRQoL improvements out to 6 years in some studies. In lifestyle and pharmaceutical intervention studies showing weight loss of 5%-10%, some aspects of HRQoL improved, although the association with weight was not typically explored. Across the 20 publications, physical versus mental HRQoL improvements were more commonly statistically significant. CONCLUSION:Overweight/obesity is typically associated with poorer HRQoL than normal weight (BMI 18.5-24.9 kg/m(2)). This systematic review of US literature demonstrated that significant weight loss after bariatric surgery may be associated with improvements in HRQoL. In non-bariatric studies with weight loss of ≥5%, improvements in some aspects of HRQoL were noted, although the causal nature of the relationship is uncertain. Although many SF-36 and IWQOL-Lite domain scores increased, improvements were typically only significant for physical, rather than mental, HRQoL. This systematic review provides evidence supporting that weight loss may improve HRQoL in people with overweight/obesity.
