Obesity construed in terms of body mass index (BMI) values, in view of undesirable gain in BF, is a risk factor for cardio-metabolic disorders. Both detrimental processes clearly evidence a scope of involutionary changes characteristic of an aging population, also standing for one of its greatest burdens.Purpose: The present study aimed to assess the changes in body composition (BC), in conjunction with the relationship between BF% and BMI, for defining overweight and obesity status in middle-aged and older adults, against the select indicator variables under study.Materials and Methods: The study involved 4799 individuals (33.7% men), PONS Project participants, aged 43– 64 years. BF% was measured with the aid of bioelectrical impedance analysis (BIA) method. Age-induced changes in BC were determined against BF%, fat mass (FM), FFM, BMI, fat mass index (FMI), and fat-free mass index (FFMI). The relationship between BF% and BMI was established with the aid of Bayesian regression models, adjusted for gender and age.Results: In both genders, BF% increased with age at a similar annual rate. The reduction of FFM was noted mainly in men, which in conjunction with BF% gain ensured BMI stability. The increase in BF% in women with stable FFM affected an increase in BMI. Regardless of the BMI threshold, the anticipated (predicted) BF% increased with age in both genders.Conclusion: Monitoring of BC is of particular importance in older adults, in view of appreciably better characteristics of both the short- and long-term health predictors, as well as overall potential for developing specifically targeted, effective health interventions.Keywords: age, body fat percentage, body mass index, body composition, obesity, public healthMacek PTerek-Derszniak MBiskup MKrol HSmok-Kalwat JGozdz SZak MDove Medical Pressarticleagebody fat percentagebody mass indexbody compositionobesitypublic healthGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 15, Pp 2301-2311 (2020)
