Body Composition Analysis in Perimenopausal Women Considering the Influence of Vitamin D, Menstruation, Sociodemographic Factors, and Stimulants Used.

ABSTRACT

(1) The perimenopausal period and menopause are physiological stages of a woman's life, and they may result in the occurrence of many health problems. The aim of this study was to assess the impact of sociodemographic factors related to the use of stimulants and the presence of menstruation and vitamin D concentration in women's health based on the analysis of their body composition parameters. (2) The study was carried out among 191 women. The diagnostic poll method was used, the levels of serum vitamin D were tested, and a body composition analysis was carried out. (3) Correlations between the vitamin D serum concentration and the following factors were established adipose tissue mass (%) (rho = -0.18; p = 0.011), visceral adipose tissue (rho = -0.18; p = 0.014), BMI (rho = -0.22; p = 0.002), muscle mass (rho = -0.19; p = 0.008), osseous tissue mass (rho = -0.18; p = 0.013), and the phase angle value (rho = -0.2; p = 0.005). A statistically significant correlation between adipose tissue mass (Mdn = 34.4 vs. 32.2; p = 0.018; η2 = 0.029), visceral adipose tissue (Mdn = 8 vs. 6; p = 0.000; η2 = 0.106), and metabolic age (Mdn = 49 vs. 42; p = 0.000; η2 = 0.098) exists. (4) The following conclusions were made (i) Menstruating women were characterized by increased body composition parameters, especially adipose tissue mass, visceral adipose tissue, and metabolic age. Greater muscle and osseous masses were noted in regularly menstruating women. (ii) A correlation between the vitamin D concentration and body composition parameters in the studied women was observed.
