Association of all-cause mortality with overweight and obesity using standard body mass index categories: a systematic review and meta-analysis.

ABSTRACT:

Importance

Estimates of the relative mortality risks associated with normal weight, overweight, and obesity may help to inform decision making in the clinical setting.

Objective

To perform a systematic review of reported hazard ratios (HRs) of all-cause mortality for overweight and obesity relative to normal weight in the general population.

Data sources

PubMed and EMBASE electronic databases were searched through September 30, 2012, without language restrictions.

Study selection

Articles that reported HRs for all-cause mortality using standard body mass index (BMI) categories from prospective studies of general populations of adults were selected by consensus among multiple reviewers. Studies were excluded that used nonstandard categories or that were limited
