Fact of the day

Pooling 684 observational studies covering 44,979,527 adults, global metabolic syndrome prevalence was estimated at between 19% and 31%, with the highest figures reported in South Asia and in Latin America and the Caribbean. Prevalence did not differ significantly between pre-pandemic and post-pandemic studies.

⚠What it shows: Proportional meta-analysis of 684 observational studies reporting crude prevalence; heterogeneity was substantial, metabolic syndrome definitions and sampling differ between studies, and the socioeconomic correlates come from meta-regression, so they are ecological associations rather than causes.Study · Eur J Cardiovasc Nurs
