Lower Levels of Total Cholesterol Seen in More Recent Birth Cohorts
FRIDAY, Dec. 6, 2024 -- More recent birth cohorts have lower levels of total cholesterol and fasting triglyceride levels, and higher levels of fasting glucose, according to a study published online Dec. 6 in JAMA Network Open.
Xiaoning Huang, Ph.D., from the Northwestern University Feinberg School of Medicine in Chicago, and colleagues quantified national trends in total cholesterol, fasting triglyceride, and fasting glucose levels among cohorts born between 1920 and 1999 to examine the association of these patterns with body mass index (BMI) using data from the National Health and Nutrition Examination Survey 1999-2000 to 2017-2020 cycles.
Data were included for 52,006 participants, weighted to represent 264,664,915 U.S. adults. The researchers found that the mean difference per one-decade younger birth cohort was −7.1, −13.1, and 2.7 mg/dL for total cholesterol level, fasting triglyceride level, and fasting glucose level, respectively, for the 50th percentile of measures. The associations between birth cohort and lipid levels were attenuated by BMI, while the association with fasting glucose levels was enhanced by BMI. However, of the associations between birth cohorts and cardiometabolic outcomes, up to 80 percent were not mediated through BMI.
"While the mean lipid profile in younger generations was improved compared with older generations, this improvement hinges on an ongoing push to continue to educate the public and health care professionals about modifying risk even at a young age," the authors write.
