Introduction: Cigarette smoking is an intractable public health problem that carries a threat to the health of the entire population. Smoking is a known risk factor for chronic obstructive pulmonary diseases, cardiovascular diseases, certain cancers especially lung cancer. Objectives:To assess the effect of cigarette smoking on peak expiratory flow rate (PEFR) among cigarette smokers and examine whether PEFR differs between cigarette smokers and non-smokers. Materials and Methods: This is cross-sectional comparative study was done for one year from July 2014 to June 2015. A total of 150 subjects were recruited from the medicine and allied outpatient departments of Mymensingh Medical College Hospital and Mymensingh locality. They are divided into 50 non-smokers (Group I) and 100 smokers (group II) with a duration of smoking 5-10 years (group IIA) and more than 10 years (Group IIB). PEFR was recorded by using Wright’s mini Peak flow meter. A questionnaire including demographic data was completed in all cases. The data were collected and analyzed using SPSS version 11.5. Results: Mean PEFR among non-smokers was 449.20±6.83 L/min whereas among smokers of 5-10 years duration(Group IIA) and above 10 years duration (Group IIB), it was 301.20±2.17 L/min and 297.80±2.54 L/min respectively. Mean PEFR values were significantly lower in smokers than non-smokers of both groups. Conclusion: Cigarette smoking has deleterious effects on lung function causing a significant reduction of PEFR in smokers compared to nonsmokers. Coordinated national strategies for tobacco prevention, cessation, and control are essential for the establishment of a smoke-free environment. JAFMC Bangladesh.

“…As supported by research conducted by Sawant (2019), the prevalence of abnormal PEF was found in 84% of smokers. 8 Another parameter that can be used to see a decrease in lung function due to smoking is forced expiratory volume in 1 second (FEV1). A study conducted in Switzerland reported a decrease in FEV1 of 10.4 mL in men and 13.8 mL in women for each pack of cigarettes used per day.…”

BackgroundIndonesia has highest prevalence of smokers above 15 years old. According to WHO, with a percentage of 76.2%. Smoking‐induced lung damage is characterized by inflammation, leading to the destruction of lung parenchyma and airway obstruction, ultimately worsening lung function parameters. This study aims to investigate the correlation between smoking based on the Brinkman Index (BI) and peak expiratory flow (PEF) rate.MethodsBrinkman Index was calculated by obtaining smoking years and the amount of smoking through history taking. PEFR was obtained by taking the average of three peak flowmeter measurements, each separated by a 2‐min interval. Inclusion criteria include male active smokers, aged 30 to 40 years, who have had a smoking history for at least 1 year. Exclusion criteria are as follows: (1) uses e‐cigarretes for smoking, (2) has a history of chronic lung diseases such as tuberculosis, pneumonia, post‐COVID‐19 syndrome, and asthma, and (3) has not smoked in the last 28 days.ResultsA total of 48 male smokers are included in this study. The mean age of participants was 35.91 years, with a history of smoking of 18.12, and 12.5 cigarettes smoked daily. Patients included in this study had BI classified as mild (47.91%), moderate (47.91%), and severe (4.16%). PEFR in patients was classified into green (10.41%), yellow (83.33%), and red (6.25%). Analysis showed significant negative correlation between BI and PEFR (r = −0.721; p < 0.001).ConclusionHigher BI correlates with a decrease in PEFR. PEFR may prove to be useful in early detection of reduced pulmonary function. Further trials conducted on larger sample sizes and evaluating other lung function parameters are recommended.

“…11 These results are also in agreement with other international studies, reporting reduced PEFR values in smokers. 12,13 Repeated inflammation is frequent and constant pathological finding in cigarette smokers destroying alveolar walls, which might be the possible reason for the reduction in PEFR. Increase secretion of inflammatory mediators causing hyper-reactivity are the hallmarks of tobacco consumption that enhances the tone of alveolar smooth muscles.…”

“…Increase secretion of inflammatory mediators causing hyper-reactivity are the hallmarks of tobacco consumption that enhances the tone of alveolar smooth muscles. 12 Alveolar wall thickness and narrowing due to bronchopulmonary leakage and edema eventually causes decreased diffusing capacity and further aggravate airway obstruction leading to a reduction in PEFR. [13][14][15] The current study showed a negative association of PEFR with smoking, β coefficient of −7.89 suggested that each unit increase in smoking rate will lead to a 7.89 unit decrease in PEFR.…”

Objective: To compare peak expiratory flow rate among smokers and nonsmokers and to establish a relation between PEFR and smoking.Methodology: A cross-sectional study was conducted at Bahria Medical and Dental College, Karachi from August to October 2020. It was comprised of 151 male smokers and nonsmokers healthy subjects of 20 to 25 years age. After taking ethical approval (ERC 21/2020), hundred and fifty one subjects, who fulfill the inclusion criteria were enrolled in the study. PEFR values were estimated by Wright’s Peak flow meter. Data was analyzed by SPSS22. Mean PEFR was compared among smokers and nonsmokers. Association between PEFR and smoking was determined by regression analysis. p-value ?0.05 was considered significant.Results: This study was comprised of 151 male participants. Of total subjects, 49 (32.5%), 102(67.5%) were smokers and nonsmokers respectively. Mean±SD age of the study participant’s was 22.74±2.657 years. Smokers have lower PEFR values as compared to nonsmokers (323.94 versus 352.65L/min.), this difference was statistically significant (p-value 0.04). Regression analysis showed the negative association of PEFR with smoking, however, this association was not statistically significant (p-value 0.17). Conclusion: Peak expiratory rate was comparatively lower in smokers than nonsmokers healthy young subjects.
