Background: Cooking smoke is a major source of indoor air pollution affecting millions of people worldwide. To date, there has been no epidemiological study to show the variation in health effects resulting from work at different kinds of restaurants in Thailand. This study determines lung function and chronic respiratory symptoms of workers in four types of eateries commonly found in Thailand. Methods: This is a cross-sectional study of 321 people working in four common types of restaurants in Thailand: ‘tamsang’ restaurants (from the Thai word ร้านอาหารตามสั่ง, a restaurant that makes a variety of foods to order) (170 people), papaya salad restaurants (51 people), noodle restaurants (50 people), and barbecue stalls (50 people).  The restaurant workers’ demographic data as well as information on their working conditions was collected using a questionnaire administered in a face to face interview. Each worker’s peak expiratory flow rate was measured using a portable peak flow meter. Results: This study found that working in a ‘tamsang’ restaurant is associated with a higher risk of poor lung function (OR = 2.59, 95% CI 1.33–5.06) and a higher prevalence of moderate dyspnea symptoms (OR = 3.79, 95% CI 1.63–8.79) compared to working in a papaya salad restaurant. The study also found that each of the following were associated with poor lung function and/or chronic respiratory symptoms: cooking with palm oil, having irritated teary eyes while cooking, cooking without a ventilation hood, long past experience working at restaurants, and working in a small cooking area (1–6 m2). Conclusions: Work in different kinds of restaurants with variations in cooking methods and work conditions produces diverse effects on airway and lung function. Regulatory organizations should pay careful attention to protecting the health of restaurant workers, especially those working in ‘tamsang’ restaurants.

Background: The objective of this research was to study the peak expiratory flow rate (PEFR) values and its correlation with height in children aged between 6 to 14 years and height.Methods: A cross sectional study was conducted among 1205 children aged 6 to 14 years in department of paediatrics at a medical college hospital. In a pre-structured questionnaire, the age, sex, height and PEFR values were recorded. PEFR was considered as primary outcome variable. SPSS version 20 was used for data analysis.Results: Among 1205 study participants, height showed a steady relationship with PEFR. As height increases PEFR increases progressively in both boys and girls. (R2=0.691). The linear regression model for PEFR with height of all age shows, one centimeter increase in height there was 5.1% increase in PEFR with a constant (-458.0) and a 95% confidence interval 4.9 to 5.3, a lesser R2=69.1% which was found to be statistically significant.Conclusions: The PEFR values derived and its height correlation in this study can be used as reference for children in and around Chennai district.

Introduction: Modern lifestyle has resulted in an increased prevalence of cardiovascular and respiratory diseases along with being overweight. An interaction between the three factors has also been demonstrated. Aim: The study aimed to assess the relationship of Body Mass Index (BMI), Mean Arterial Pressure (MAP) and Peak Expiratory Flow Rate (PEFR) in healthy individuals. Materials and Methods: This cross-sectional, observational study was done in the Department of Physiology, KGMU, Lucknow from 30 July 2019 to 30 July 2020. Forty healthy individuals, aged 18-35 years were assessed for height, weight, blood pressure and spirometric parameter of PEFR. PEFR was chosen as it was a reliable representative of airways functioning. PEFR reflects proximal airway calibre changes which might be due to effect of airway geometry. A correlation test was run to test the relation between BMI and PEFR and MAP and PEFR. Results: A weak correlation (r=-0.136) was noted between BMI and PEFR indicating that as BMI increased, PEFR compromised. A linear correlation was observed between MAP and PEFR. Conclusion: The present study confirms a weak association of BMI and MAP with PEFR.

Each worker’s peak expiratory flow rate was measured using a portable peak flow meter. Results: This study found that compared to the other three types of restaurants, working in a ‘tamsang’ restaurant has more adverse health effects. Participants from ‘tamsang’ restaurant were at greater  of poor lung function (OR = 2.59, 95% CI 1.33–5.06) and  moderate dyspnea symptoms (OR = 3.79, 95% CI 1.63–8.79) compared to participants  from papaya salad restaurant. The study also found that each of the following were associated with poor lung function and/or chronic respiratory symptoms: cooking with palm oil, having irritated teary eyes while cooking, cooking without a ventilation hood, long past experience working at restaurants, and working in a small cooking area (1–6 m 2).
