Respiratory function, physical activity and body composition in adult rural population

objective. The aim of this study was to evaluate functioning of the respiratory system and to estimate the correlation between the function parameters of the respiratory system and the level of physical activity and body composition in the adult rural population. The study involved a group of 116 people from rural population aged 35–60 years, staying on 3-week rehabilitation camps. They were divided into two groups: men (29) and women (87). The somatic features: body height, body weight, Body Mass Index (BMI) and body copmposition were analysed, on the status of smoking and declared level of physical activity (PA) was checked. For the evaluation of the functional parameters of the respiratory system the pattern of flow volume curve was used. The following parameters were determined: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), MEF50 (maximum expiratory flow at 50% of VC) and Tiffenau index. Hand grip and maximum torque of the knee join flexor and extensor muscles was measured. As expected, men had significantly higher levels of respiratory parameters. In analyzing the status of smoking cigarettes, it can be stated that the majority of subjects are smokers. conclusions. The values of functional parameters of the respiratory system were suitable for the age they were within the norm and did not show lung ventilation disorder. Most subjects of the study declared low physical activity which may be due to manual work on the farm. Smoking cigarettes significantly lowered the value of such parameters as FEV1, PEF and MEF50 only in the male group but the values did not indicate ventilatory disorder. Parameters of the respiratory system show the highest correlations with the parameters of muscle strength. Significant correlations with body compositions parameters (FFM, water) have been noticed too

The suggested effects include alteration in bone remodeling rates as well as the multifaceted etiology of edentulism. There is also a question if other body-related variables besides BMD, such as body composition, may be associated with tooth number and general periodontal health. The aim of this study was to evaluate if tooth number and marginal periodontal status are associated with body composition and BMD in a sample of elderly women. Materials and methods: The study involved 91 postmenopausal women. Data included basic anthropometric characteristics, body composition via bioelectrical impedance analysis, and BMD analysis at the distal end of the radial bone of the nondominant arm via peripheral dual-energy X-ray absorptiometry. A dental examination was performed to assess tooth number, periodontal pocket depth (PD), and gingival bleeding. Results: In nonosteoporotic women, a significant positive correlation was found between BMD and lean body mass, total body water, and muscle mass. The indicators of bone metabolism correlated negatively with PD. Such relationships did not appear in osteoporotic women. In both groups, basic anthropometric characteristics and body composition were significantly and positively correlated with PD and bleeding on probing. Conclusion: The results suggest that body composition and BMD are not significantly correlated with tooth number and gingival bleeding.
