Introduction:
Adverse health behaviors changes are reported during emerging adulthood, inter alia the reduced level of physical activity (PA), worse diet quality etc. There are only very few studies concerned with the relationship between health behaviors and body composition in healthy young adults.
Aim:
The aim was to investigate the relationship between behavioral components of prohealthy lifestyle and body composition assessed by bioelectrical impedance (BIA) in the cohort of Polish young adults.
Material and methods:
A cross-sectional observational study of health behaviors, anthropometric indices and BIA body composition was conducted in Polish young adults (n = 92) aged 18–24 (mean 19.33, SD 0.915), 71 females. Behavioral variables included: general health behaviors, PA, eating behaviors and nutritional knowledge. Body composition was analyzed by means of the BIA phase-sensitive 8-electrode medical SECA mBCA 525 device.
Results and discussion:
A higher level of PA was associated with a lower volume of visceral adipose tissue in females (r = –0.27; P < 0.05). In the males, the intensification of unhealthy diet was negatively correlated with the muscle mass (r = 0.65; P < 0.01), and the higher level of nutritional knowledge resulted in a smaller waist circumference (r = –0.45; P < 0.05). Behavioral components of pro-healthy lifestyle were not significant predictors of body composition/anthropometric indices such as waist circumference, fat mass index, fat free mass index and body mass index.
Conclusions:
The reported studies provide an important insight into the sex-specific correlations between the behavioral components of the pro-healthy lifestyle and body composition in healthy young adults.
