Association of BMI and pulmonary function test among adults: A cross-sectional study

Aim: To evaluate smoking and COPD prevalence amongst teachers working in the schools of Kocaeli City, Turkey.Method: In this cross-sectional study, a questionnaire focusing on respiratory symptoms and smoking habits was adminis- tered to all participants who accepted to join the study. All sub- jects also underwent a physical examination and a pulmonary function test performed with portable spirometer. According to GOLD criteria, subjects who had post-bronchodilator FEV1/FVC < 70% and negative reversibility test were classi- fied as COPD. Results: A total of 685 teachers were included [female n = 307 (45%), male n = 378 (55%)] with mean age 38.9 ± 8.9 years. Smoking habit was evaluated in 660 subjects: 291 (44.1%) were smokers, 252 (38.2%) were non-smokers and 117 (17.7%) were ex-smokers. Pulmonary function test was available in 651 subjects and 510 (78.3%) were defined as normal on spirometric analysis. Small airway obstruction was found in 115 of the cases (17.7%) in whom FEF25-75 level was found to be lower than 70% predicted. FEV1/FVC level was lower than 70% in 16 subjects (2.5%). Five subjects who had positive reversibility test were excluded from the study. The remaining 11 subjects who were considered as COPD consisted of 2 (18%) females and 9 (82%) males. Six of these subjects were aged over 40 years. Conclusion: Spirometry has an important role in early diagno- sis of COPD. Spirometric evaluation of cases with risk factors for COPD could be helpful in diagnosing patients before the progressive decline in lung function begins. Further studies are needed to evaluate whether the interventional strategies at this stage such as smoking cessation could prevent the progression of disease.

ABSTRACT CONTEXT AND OBJECTIVE: The combined effect of obesity and asthma may lead to significant impairment of quality of life (QOL). The aim here was to evaluate the prevalence of asthma among obese individuals, characterize the severity of impairment of quality of life and measure its relationship with pulmonary function. DESIGN AND SETTING: Observational cross-sectional study in public university hospital. METHODS: Morbidly obese individuals (body mass index > 40 kg/m2) seen in a bariatric surgery outpatient clinic and diagnosed with asthma, were included. Anthropometric data were collected, the Standardized Asthma Quality of Life Questionnaire (AQLQ(S)) was applied and spirometry was performed. The subjects were divided into two groups based on the median of the score in the questionnaire (worse < 4 and better > 4) and were compared regarding anthropometric data and pulmonary function. RESULTS: Among the 4791 individuals evaluated, 219 were asthmatic; the prevalence of asthma was 4.57%. Of these, 91 individuals were called to start multidisciplinary follow-up during the study period, of whom 82 answered the questionnaire. The median score in the AQLQ(S) was 3.96 points and, thus, the individuals were classified as having moderate impairment of their overall QOL. When divided according to better or worse QOL, there was a statistically difference in forced expiratory flow (FEF) 25-75%, with higher values in the better QOL group. CONCLUSION: The prevalence of asthma was 4.57% and QOL was impaired among the asthmatic obese individuals. The worst QOL domain related to environmental stimuli and the best QOL domain to limitations of the activities. Worse QOL was correlated with poorer values for FEF 25-75%.

The Relationship

Background: Obesity has long been recognized to have significant effect on respiratory functions. Many studies have reported exponential decrease in pulmonary function test (PFT) with increasing body mass index (BMI), which is a crude indicator of obesity. Also, the relationship between BMI and PFTs varies with age, race, geographical region and the different obesity standards used. To the best of our knowledge, not many studies have been done to examine the relationship between obesity and lung volumes among adults in our region, Jammu. This cross-sectional study was carried out with the objective of evaluating the effect of obesity on lung function test in obese but otherwise healthy adults of Jammu region.Methods: This cross-sectional study was conducted in Jammu region on subjects selected randomly from different colleges in the age group of 18-40 years. The study involved 300 subjects; divided into three groups of 100 each, based on BMI into normal, overweight and obese groups. Four respiratory parameters viz. FVC (Forced Vital Capacity), FEV1 (Forced Expiratory Volume in 1 second), FEV3 (Forced Expiratory Volume in 3 seconds), and MVV (Maximum Voluntary Ventilation) were used to assess their lung functions.Results: All the respiratory parameters exhibited statistically significant decrease in obese groups as compared to normal and overweight groups.Conclusions: The present study suggests that obesity alters the respiratory physiology by producing a restrictive ventilatory pattern.

Hypertensive Patients

Background. Hypertension imposes stresses on many organs like heart and kidney. However, studies that show the effect of hypertension on the lungs are limited. Objective. To assess pulmonary function status of hypertensive patients aged 30-64 years at Zewditu Memorial Hospital, 2017. Methods. Hospital based comparative cross-sectional study was conducted on 61 hypertensive patients (cases) and 61 nonhypertensive clients (controls) aged 30-64 years. Computerized spirometry was done in all cases and controls which were selected by systematic sampling technique. The study was conducted from January 20, 2017, to May 25, 2017. Result. The values of FVC, FEV1, and FEF25-75% were 3.52±1.02 liters, 2.97±0.89 liters, and 3.34±1.3 liters/second in hypertensive patients and 4.31±0.82 liters, 3.54±0.7 liters, and 3.94±1.09 liters/second in controls, respectively. These values were significantly lower (p<0.05) in hypertensive patients compared to controls. Restrictive pulmonary defect was dominant in hypertensive patients. FEV1% which was 85%±7% in hypertensive patients and 82%±5% in controls was significantly higher (p<0.05) in hypertensive patients compared to controls. Conclusion. Hypertensive patients exhibit lower pulmonary function values. Routine check-up of the pulmonary function status of such patients should be done to prevent undesired outcomes.
