Waist to height ratio as a simple tool for predicting mortality: a systematic review and meta-analysis
Authors' conclusion
Higher levels of WHtR, indicating central obesity, were associated with an increased hazard of CVD and all-cause mortality. This measure can be used in the clinical setting as a simple tool for predicting mortality.
Study context
- Population
- Cohort studies in the general population reporting HRs for waist-to-height ratio (WHtR) and all-cause and cause-specific mortality; searched PubMed, Web of Science, Scopus, Google Scholar until May 202220 studies
- Comparison
- Higher vs lower waist-to-height ratio, categorical or continuous
- Outcome
- All-cause mortality
Methodological detailsrandom effect meta-analysis, Newcastle-Ottawa quality assessment, GRADE certainty assessment, Quality assessment score of all included studies was high
