Abstract

Objectives An increasing percentage of the US population is obese. Cardiometabolic risk in the population increases with body mass index (BMI), but whether this correlation changes over time is unknown. We analysed the National Health and Nutrition Examination Survey (NHANES) database from 1999 to 2016 to determine if the prevalence of cardiometabolic disease and cardiovascular events within each BMI category is changing over time as the BMI of the population is increasing. Study design For each of the nine survey cycles covering this period, we divided the population by BMI category (normal, overweight, class 1 obesity, class ≥2 obesity) and subsequently by the presence of cardiovascular events or cardiometabolic disease. NHANES participants are a group of 5000 individuals/cycle selected to be representative of the US population. We used the weighted data sets to perform trend analyses for each risk/BMI group adjusted for relevant confounders. Results The distribution of the highest risk category (cardiovascular event) has not changed over time within any BMI category. The distribution of the lowest risk category (cardiometabolically healthy) increased significantly over time in all BMI categories. This was noted in the 18-to 45-year subgroup but not in the group aged >45 years. Conclusions The increase in the prevalence of overweight and obese individuals might be associated with a a € healthy obesity' phenotype in those <45 years; however, individuals >45 years showed a proportional increase in associated cardiometabolic risk.
