Six cohorts with a mean age \u2264 65 years, examining all-cause mortality risk per increment in VAT area (cm\n                      <jats:sup>2<\/jats:sup>\n                      ) or volume (cm\n                      <jats:sup>3<\/jats:sup>\n                      ), showed a 11-98% relative risk increase with higher VAT parameters. However, the association lost significance after adjusting for glycemic indices, body mass index, or other fat parameters. In 4 cohorts with a mean age &amp;gt;65 years, the findings on mortality were inconsistent. Conversely, in two cohorts (mean age 73-77 years), a higher VAT density, was inversely proportional to VAT area, and implied a higher mortality risk.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A high abdominal VAT area seems to be associated with increased all-cause mortality in individuals \u2264 65 years, possibly mediated by metabolic complications, and not through an independent effect. This relationship is weaker and may reverse in older individuals, most likely secondary to confounding bias and reverse causality. An individual participant data meta-analysis is needed to confirm our findings, and to define an abdominal VAT area cutoff implying increased mortality risk.<\/jats:p>\n
