Weight Loss Interventions Have Little Effect on Quality of Life

Am Fam Physician. 2005 Oct 1;72(7):1328.

Clinical Question: Do weight loss interventions improve health-related quality of life?

Setting: Outpatient (any)

Study Design: Systematic review

Synopsis: For this review, the authors systematically searched several databases. However, they excluded research not published in English and did not describe any attempts to find unpublished studies. After obtaining the initial articles, the authors applied exclusion criteria (i.e., studies of children or pregnant women) and were left with a few hundred studies. The authors then read the abstracts to exclude nonrandomized studies and those that did not address quality of life, leaving 34 eligible trials.

The authors independently extracted the data and assessed the quality of the studies. In general, the studies had several methodologic shortcomings that typically biased the findings in favor of the intervention. The included trials were six weeks to two years in duration and evaluated a variety of interventions (e.g., medications, surgeries, behavior modifications). Only nine of the 34 studies showed improvement in general health-related quality of life. There was no overall effect on depression.

Bottom Line: Based on existing research, weight loss interventions have little effect on health-related quality of life. The overall quality of the existing research, however, is poor. (Level of Evidence: 1a)
