Reason behind Death The pattern and magnitude of the hazard ratios varied according to the broad reason behind death . The hazard-ratio estimates associated with a BMI of 25.0 or more were highest for loss of life from cardiovascular conditions and were lowest for cancers. For a BMI of less than 22.5, the hazard ratios had been highest for other notable causes of loss of life and were not elevated for deaths due to cancer. Although absolute death rates varied relating to sex, the hazard ratios were similar. Discussion In this large, pooled analysis of prospective studies, both overweight and obesity were associated with increased all-trigger mortality in analyses limited to participants who never smoked and didn’t have diagnosed cancer or cardiovascular disease.
