Objective Obesity is becoming a global public health problem, but it is unclear how it impacts different generations over the life course. Here, a descriptive analysis of the age‐related changes in anthropometric measures and related cardiometabolic risk factors across different generations was performed. Methods The development of anthropometric measures and related cardiometabolic risk factors was studied during 26 years of follow‐up in the Doetinchem Cohort Study (N = 6,314 at baseline). All analyses were stratified by sex and generation, i.e., 10‐year age groups (20‐29, 30‐39, 40‐49, and 50‐59 years) at baseline. Generalized estimating equations were used to test for generational differences. Results Weight, BMI, waist circumference, and prevalence of overweight and obesity were higher, in general, in the younger generations during the first 10 to 15 years of follow‐up. From age 50 to 59 years onward, these measures converged in all generations of men and women. Among cardiometabolic risk factors, only type 2 diabetes showed an unfavorable shift between the two oldest generations of men. Conclusions It was observed that, compared with the older generations, the younger generations had obesity at an earlier age but did not reach higher levels at midlife and beyond. This increased exposure to obesity was not (yet) associated with increased prevalence of cardiometabolic risk factors.
