RESUMO
Background: Obesity is a global health burden. Accumulation of fat in body is associated with cardiovascular abnormalities. It is the need of the hour to conduct various autonomic function tests among obese subjects and create awareness of the drawback of obesity as it is a reversible lifestyle disorder. Aim and Objective: The aim of the study was to investigate the autonomic cardiovascular parameters in obese adult males and females and compare the result with controls. Materials and Methods: Sympathetic cardiovascular parameters of both healthy obese and non-obese subjects were compared and correlated in a tertiary medical college and hospital. Criteria for obesity were according to the WHO criteria of body mass index. The tests were carried out with Mercury Sphygmomanometer. The data were collected; statistically analyzed and valid conclusions were drawn. Results: The baseline diastolic blood pressure (DBP) and the change in DBP after isometric exercise and cold pressure test when compared between obese and non-obese subjects found to be significant. Conclusions: Obesity by causing instability in autonomic function makes disorder in cardiovascular system which may lead to disease like hypertension in later life.
RESUMO
Background: Obesity is worldwide health problem, with increasing incidence and prevalence, high costs, and poor outcomes. Accumulation of adipose tissue mass is associated with respiratory abnormalities. There is a need to conduct pulmonary function tests (PFTs) among obese subjects and create awareness of the drawback of obesity as it is reversible lifestyle disorder.Aim and Objective: The aim of the study was to assess the PFT in obese adult males and females and compare the result with controls.Materials and Methods: PFTs of healthy non-obese subjects and obese but healthy subjects were compared and correlated in a tertiary medical college and hospital. Criteria for obesity were according to the WHO criteria of body mass index. The PFTs were carried out with a computerized spirometer (Med-Spiror).The data were collected, statistically analyzed, and valid conclusions were drawn. Results: There was a statistically significant decrease in the value of forced expiratory volume (FEV) 1 and FEV3. Peak expiratory flow rate in obese males and females whereas forced vital capacity and force expiratory flow 25–75% significantly decreased anly in obese male subjects.Conclusions: Obesity influences respiratory functions. The cause of this reduction of various pulmonary functions is due to the inability of the chest wall and thoracic cavity to expand which lead to a decrease in ventilatory volumes and total lung capacity.
