“…All the parameters except FEF were decreased in AC users. Hence, the results were suggestive of mild airflow obstruction in AC users [4].…”

“…Increased airway resistance is detrimental to the air movement through the respiratory passages and affects respiration .This is reflected as decreased pulmonary function tests (especially FEV1, PEFR, FEF25-75%). Long term use of ACs is being implicated in the causation of obstructive disease like pattern [4]. The present study was conducted to evaluate the spirometry parameters in car drivers with exposure to AC over a long period.…”

“…The mean ± SD PEFR values for PPWs was 329.6 ± 107.2 lit/ min, while the controls presented with a far better mean PEFR values of 407.7 ± 83.2 lit/min. After reviewing similar literature on occupational exposure of organic vapours like petrol and diesel a reduction in PEFR values among PPWs was consistent, when compared to the general population( 1 , [14][15][16][17] ). Age and cigarette addiction are other factors that influence PEFR in adults.…”

Patient health questionnaire (PHQ9) Peak expiratory flow rate (PEFR) A B S T R A C TObjective: Fumes of petroleum products have an established toxic effect on haematological, respiratory and liver parameters and a definite neurotoxicity. According to study conducted in Italy, the highest concentration of benzene is in the breathing zone of petrol pump workers. This Analytical Cross-sectional study was conducted with the aim and objective to assess the effect of petrol and diesel vapours on the health status (respiratory and mental) of petrol pump workers and comparing the results with non petrol pump workers (controls). Methods: A sample size of 96 was obtained (study subject-32, controls -64). PHQ9 (Patient Health Questionnaire) and PEFR (Peak Expiratory Flow Rate) meter were used as study tools. Results: The study found a weak negative correlation (r = -0.233) between duration of exposure and PEFR. A significant difference between mean PEFR values of the two groups was observed. The PHQ9 values between the two groups were also significantly different (p = 0.022). A positive correlation exists between duration of exposure and PHQ9 values (r = +0.192).

“…Moreover, it was also reported that AC users have a predisposition to developing respiratory disorders. (34)(35)(36)(37)(38)(39)(40) Systolic BP was signi cantly higher in auto drivers than students, and it increased with age in males. This result was found to be similar to the previous studies reported.…”

Background: Lung function test is a useful indicator that measures the presence of mild abnormalities, if any. The present study aimed to compare the lung function in people from different occupations and to correlate with anthropometric measurements and blood pressure. Methods: This cross-sectional study was conducted among students, faculty, gardeners, housekeeping, and support staff of Melaka Manipal Medical College (MMMC) and auto drivers of Manipal. Peak expiratory flow rate (PEFR) and vital capacity (VC) were recorded using a digital spirometer. Breath-holding time (BHT), and blood pressure (BP) were recorded. Waist-to-hip ratio (WHR) and body mass index (BMI) were measured. The data were analyzed using the Prism statistical package. Results: Forty-one males and Thirty-two females participated in this study. PEFR did not significantly differ among the different occupations but was negatively correlated with WHR in females. For VC, male students showed a significantly higher value than gardeners, whereas female students and faculty members had a considerably higher value than housekeepers. VC negatively correlated with age in males. In females, it showed a negative correlation with age, WHR, duration of indoor non-AC exposure, and systolic BP. BHT of male students and staff was significantly higher than auto drivers, and it showed a negative correlation with age, duration of outdoor exposure, and systolic BP. Lung function parameters did not correlate with indoor AC exposure in males and females. Systolic BP was significantly higher in auto drivers than students, and it increased with age in males. In females, systolic BP negatively correlated with outdoor exposure and positively correlated with indoor non-AC exposure. Among females, WHR was significantly higher in housekeepers and staff than students and faculty. Conclusion: The study results showed that vital capacity was lowest among male gardeners and female housekeepers who tend to have occupational exposure to chemicals. Peak expiratory flow rate (PEFR) and vital capacity were lower in females with a tendency towards abdominal obesity. More considerable time spent indoors was associated with lower vital capacity and higher systolic blood pressure in females.
