Age-Related Differences in Body Fatness and Nutritional Status in Large Sample of Serbian Women 20–70 Years of Age

Obesity due to increased body fatness has been recognized internationally as one of the leading factors affecting individual and public health. The aim of this study was to determine age-related differences in body fatness in a representative sample of women in Serbia. The study included 1937 Serbian females aged 20 to 69.9 years from all regions of the Republic of Serbia. The obesity and body fatness were analyzed using body mass index (BMI), body fat mass (BFM), percent of body fat (PBF), body fat mass index (BFMI), and visceral fat area (VFA). Multivariate analysis of variance with post hoc pairwise comparisons revealed the largest differences between the age categories in VFA followed by BFMI, PBF, and BMI. The prevalence of overweight, obese, and extremely obese subjects in the overall sample by BMI was 30.77, 1.32, and 1.40%, respectively. The prevalence was higher when calculated by PBF, with 37.84 and 20.11% for overweight and obese subjects. The prevalence of overweight and obesity, as calculated by BMI and PBF, was higher in older age groups of Serbian women. The prevalence of overweight women in the oldest group was 4.32 times higher, while the rate of obesity was 8.67 times higher than in the youngest group. Our results are a good basis for planning and implementing preventive health activities and monitoring changes in morphological parameters in Serbian women of different ages.
