Associations of short‐term changes in obesity indices with all‐cause mortality and cardiovascular disease

Obesity (Silver Spring)Published Longitudinal cohort study

Authors' conclusion

Short-term changes in obesity indices show complex mortality risks, urging personalized approaches beyond a simple weight loss focus.

Study context

Population
Participants of the MJ Health Centre with repeated obesity measures over 1, 3 or 5 years1-year study
Participants
43,304 participants
Exposure
Short-term reduced or increased obesity indices vs stable
Outcome
All-cause mortality and CVD risk
Follow-up
Median 15.8, 13.9 and 12.3 years (1-, 3-, 5-year studies)
Methodological detailstime-dependent coefficient Cox regression, restricted cubic splines, multivariable linear regression
  • Time-dependent coefficient Cox regression
  • Restricted cubic splines
  • Multivariable linear regression

Main finding

As reported in the abstract

All-cause and CVD mortality
  • All-cause mortality negatively associated with short-term weight and BMI changes; greater reductions, poorer outcomes
  • Short-term reduced weight and BMI vs stable: greater risk of all-cause mortality and cardiovascular disease (CVD)-specific mortality (5-year study only)
  • 1- and 3-year reduced or 3-year increased waist circumference and waist to height ratio: higher all-cause and CVD deaths vs stable, respectively

Observational data: associations, not effects.

Further findings

Nonlinear relationships with all-cause mortality

Lower cutoff values for short-term changes in obesity indices in predicting all-cause mortality

Framingham Risk Score / CVD profiles

Decreased obesity indices significantly improved CVD profiles
