A Narrative Review of Cardiometabolic Profiles among U.S. Adults: Temporal Trends and Implications

To provide a narrative overview of trends and disparities in the cardiometabolic profiles of U.S. adults by synthesizing findings from nationally representative studies conducted between 1999 and 2020.

During the study period, the cardiometabolic profiles of U.S. adults displayed a complex mix of trends. While there were notable improvements in specific risk factors, such as reductions in total cholesterol, triglycerides, and low-density lipoprotein cholesterol levels, other aspects of cardiometabolic health worsened. The mean body mass index and hemoglobin A1c levels increased, accompanied by significant rises in the prevalence of obesity, type 2 diabetes, and metabolic syndrome. Despite some progress in blood pressure and lipid profiles, the overall cardiometabolic health of the population declined, with only a small percentage of adults maintaining optimal health by 2018. Furthermore, significant disparities persisted across racial and socioeconomic groups, with non-Hispanic Black participants and those with lower education and income facing higher cardiometabolic risks compared to their counterparts. Despite improvements in certain aspects of cardiometabolic profiles among U.S. adults, significant challenges remain, particularly with the rising rates of obesity, type 2 diabetes, and metabolic syndrome. Persistent disparities in cardiometabolic health across sociodemographic groups emphasize the need for comprehensive public health strategies that address medical care, lifestyle factors, and social determinants of health. Future efforts should prioritize reducing these disparities and enhancing health equity to mitigate the overall burden of cardiometabolic disease.
