A new study from CHOICES, “Excess mortality associated with elevated body weight in the USA by state and demographic subgroup: A modelling study.” was published online today in eClinicalMedicine.
The study team, led by Zach Ward, developed a nationally-representative microsimulation (individual-level) model of US adults between 1999 and 2016, based on risk factor data from 6,002,012 Behavioral Risk Factor Surveillance System respondents, and simulated counterfactual scenarios to estimate excess mortality attributable to different levels of excess weight and smoking history. They estimate that excess weight was responsible for more than 1300 excess deaths per day (nearly 500,000 per year) and a loss in life expectancy of nearly 2·4 years in 2016, contributing to higher excess mortality than smoking, with rates varying by gender, race and ethnicity, and US state.
