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.

Spirometry and Peak Expiratory Flow Rate (PEFR) are important measurements in diagnosing and monitoring of COPD and asthma. Ethnic specific reference equations are necessary in interpretation of these parameters. However, equations for Sri Lankan Tamil adults are not available. This study aims to establish reference equations for lung function parameters of Sri Lankan Tamils. A descriptive cross sectional study was carried out in all 5 districts of Northern Sri Lanka. Participants were selected by cluster sampling. Base line data were obtained by a questionnaire. Height, sitting height, weight, arm span, mid arm circumference, and chest expansion were measured. Respiratory functions were assessed by a calibrated spirometer (Cosmed Micro Quark, Italy) and Wright compatible peak expiratory flow meter. Means, and standard deviations for Vital Capacity (VC), Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), FEV1%, Peak Expiratory Flow Rate (PEFR) and for other forced expiratory parameters of 775 males and 687 females were determined. Lung function parameters have significant p<0.05 positive correlations with most of the anthropometric measures. Age had a significant p<0.05 negative correlation with lung function parameters in adults >20 years and positive correlation p<0.05 in 14–20 years group. Step wise multiple regression analysis was used to determine the prediction equations. Also equations based on age, height and age, arm span were derived. Age, height based equations were retested in the same population. Predicted values by the developed equations had better agreement than that of GLI 2012 equations. This can be useful in assessing the respiratory function in Sri Lankan Tamil population as there are no already existing equations.

Background: Asthma remain the most common chronic inflammatory lung disease in childhood. Asthma management needs lung function assessment. Peak Expiratory Flow Rate (PEFR) is one of the lung function test. PEFR has been used as measure of ventilatory capacity for long mainly because of a simple, less tiring procedure than other lung function test. It is easy to use, inexpensive, portable, reliable can be used by patients, parents, home & clinic. There is no national nomogram on PEFR in Bangladesh. We always use the nomogram of other countries for diagnosis, management of Asthma. This study was taken to establish what is the normal pattern of PEFR in Bangladeshi children of rural and urban area and to construct nomogram of PEFR in healthy Bangladeshi children. Materials and methods : It is a cross sectional study conducted in different 6 schools (Urban & rural) in Chattogram District of both sexes (5-15 yrs old) in equal proportion of child. Study period was from April 2009 to November 2009 under supervision of Pediatrics Department of Chattogram Medical College. Sample was selected by non-probability technique. Data were collected by pretested questionnaire including exclusion criteria. Results: A total of 1424 healthy school children (Age 5-15 yrs) of equal sexes of both rural and urban school were included during study. The best of three PEFR of boys ranged from 90 to 750 I/min (Mean 291 I/min, SD 143) and in case of girls ranged from 80 to 540 (L/min (mean 236 L/min, SD 94.38). The positive correlation of PEFR with various anthrometric parameters specially height and observed difference with boys and girls. The most significant correlation was observed PEFR with height and also found different value of PEFR between rural and urban children. Conclusion : This study concluded that there is significant difference of PEFR between Bangladeshi boys and girls (5-15 yrs). Height is the best predictor of PEFR value than any other anthrometric parameters PEFR value of Bangladeshi Girls is lower than that of Boys and significant difference between PEFR values among urban & rural Bangladeshi children.

Ventilatory Lung Function

Peak expiratory flow rate (PEFR) is the maximal expiratory flow rate sustained by a subject for at least 10 milliseconds expressed in Litre per minute (L/min). PEFR is a simple, reliable, reproducible and easily measurable ventilatory lung function test. This simple test had been measured by various types and shapes of instruments for long since, now mini- Wright peak flow meter is widely used to measure the of PEFR values. Mini-Wright peak flow meter is cheap, easily portable and reproducible device for PEFR even below the age 5 years. Different countries use their own nomogram or prediction equation to find out mean PEFR values of particular height. Similarly, the prediction equation for calculation of PEFR values of Bangladeshi boys and girls are 5.96XHeight-495 and 5.70XHeight-479 respectively. Peak expiratory flow rate is very useful tool for diagnosis, management and follow up of reversible airway diseases.

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). 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.
