Associations of anthropometric indices with all-cause and cause-specific mortality among US adults with a self-reported history of cancer: a population-based cohort study.

TL;DR

Higher ABSI was associated with higher all-cause and CVD mortality among U.S. adults with a self-reported history of cancer, while continuous BRI and BMI were not independently associated with outcomes.

Key Findings

Higher ABSI was independently associated with higher all-cause mortality among US adults with a self-reported history of cancer.

  • Analysis of 3,230 NHANES participants (2003-2018) using survey-weighted Cox models.
  • Each 1-SD higher ABSI: HR 1.24, 95% CI 1.11-1.38 for all-cause mortality.
  • 937 all-cause deaths occurred during a survey-weighted median potential follow-up of 7.9 years.
  • Models were adjusted for sociodemographic, behavioral, and cancer-related factors.

Higher ABSI was strongly associated with CVD mortality.

  • Each 1-SD higher ABSI: HR 1.55, 95% CI 1.26-1.90.
  • 197 CVD deaths occurred during follow-up.

ABSI was not significantly associated with cancer mortality.

  • Each 1-SD higher ABSI: HR 1.12, 95% CI 0.96-1.29.
  • 315 cancer deaths occurred during follow-up.

Continuous BRI and BMI were not independently associated with the mortality outcomes in the primary models.

  • The abstract reports that continuous BRI and BMI were not independently associated with all-cause, cancer, or CVD mortality.

Underweight BMI category was associated with higher all-cause mortality.

  • Underweight BMI: HR 2.44, 95% CI 1.46-4.08 for all-cause mortality.

BMI showed a nonlinear association with all-cause mortality.

  • P for nonlinearity = 0.002.
  • Nonlinear analyses were performed as part of the study.

The ABSI findings were robust across sensitivity analyses.

  • ABSI findings 'remained similar across sensitivity analyses'.
  • The authors state further studies are needed to confirm the associations.

What This Means

This study looked at about 3,200 US adults who reported having had cancer, using national health survey data collected from 2003 to 2018. Researchers tested whether different body measurements were linked to dying from any cause, from cancer, or from heart and blood vessel disease over roughly 8 years of follow-up. A measure called ABSI (a body shape index, which accounts for waist size relative to height and weight) stood out. People with higher ABSI had a higher risk of dying overall and of dying from cardiovascular disease, but the link with cancer death was not statistically clear. In contrast, BMI and another shape measure (body roundness index) were not independently tied to death risk when treated as continuous measures. Being underweight by BMI was linked to higher overall mortality, and the BMI relationship with death was not a straight line. This research suggests that where body fat is carried, not just total weight, may matter for survival after cancer, and that BMI alone may miss important information. Because this was an observational study relying on self-reported cancer history, it cannot show cause and effect, and the authors note that more studies are needed to confirm the results.
