Depressive symptoms, sleep quality, physical fitness, and fatigue among adult women with different obesity status

PurposeThe aim of this cross-sectional study was to examine the association between depressive symptoms, sleep quality, objectively assessed physical fitness, and fatigue, among a sample of adult women with different obesity status.MethodsOne hundred and ninety-four volunteer adult women (36.111.1 years) participated in the study. Based on body mass index (BMI), the participants were allocated into three groups: normal weight (n=134), overweight (n=32), and obese (n=25). Physical fitness-related parameters such as aerobic fitness, flexibility, lower limb explosive strength, isometric handgrip strength, and sprint performance were assessed with a battery of field tests. Total body fat and trunk fat levels were assessed by bioelectrical impedance analysis. Depressive symptoms were assessed using the Beck depression inventory, sleep quality was assessed using the Pittsburg sleep quality index, and fatigue levels were examined using the fatigue severity scale.ResultsObese women experienced a significantly worse score regarding depressive symptoms (p<0.05). Similarly, the obese and overweight women were found to exhibit lower levels of aerobic fitness compared to women with normal BMI (p<0.05). All examined body composition variables were shown to be inversely associated with the score on all physical fitness tests as well as with poor sleep, depressive symptoms, and fatigue levels (p<0.05).ConclusionsDepressive symptoms and performance on various physical fitness tests were found to be significantly impaired in obese and overweight adult women indicating the negative impact of increased body weight in health and well-being.
