Prevalence of water pipe smoking in the city of Mashhad (North East of Iran) and its effect on respiratory symptoms and pulmonary function tests.

Boskabady MH, Farhang L, Mahmoodinia M, Boskabady M, Heydari GR - Lung India (2014)

Bottom Line: There were negative correlations between PFT values and positive correlation between RS and duration, rate, as well as total smoking (duration X rate) (P < 0.05 to P < 0.001).In this study the prevalence of WP smoking in Mashhad city was evaluated for the first time.The results also showed a significant effect of WP smoking on PFT values and respiratory symptoms.

ABSTRACT

Background: The prevalence of water pipe (WP) smoking was studied using a standard questionnaire. Pulmonary function tests were also compared between WP smokers and non-smokers.

Materials and methods: The prevalence of WP smoking was studied using a standard questionnaire. Pulmonary function tests including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), maximal mid-expiratory flow (MMEF), peak expiratory flow (PEF), maximal expiratory flow at 75%, 50%, and 25% of the FVC (MEF75,50,25) were compared between WP smokers and non-smokers.

Results: A total of 673 individuals including 372 males and 301 females were interviewed. The number of WP smokers was 58 (8.6%) including 24 males (6.5%) and 34 females (11.3%). All pulmonary functional test (PFT) values in WP smokers were lower as compared to the non-smokers (P < 0.05 to P < 0.001). The prevalence and severity of respiratory symptoms (RS) in WP smokers were higher than non-smokers (P < 0.05 to P < 0.001). There were negative correlations between PFT values and positive correlation between RS and duration, rate, as well as total smoking (duration X rate) (P < 0.05 to P < 0.001).

Conclusion: In this study the prevalence of WP smoking in Mashhad city was evaluated for the first time. The results also showed a significant effect of WP smoking on PFT values and respiratory symptoms.

Comparison of pulmonary functional tests (PFT) between water pipe (WP) smokers and non smokers (controls) subjects. Values were presented as mean ± SD of percent predicted (for smokers and non smokers n = 58 and 50 respectively). FVC = Forced vital capacity, FEV1 = Forced expiratory volume in one second, MMEF = Maximal mid expiratory flow, PEF = Peak expiratory flow, MEF75, MEF50, and MEF25 = Maximal expiratory flow at 75%, 50%, and 25% of the FVC, respectively. * = P < 0.005, * = P < 0.001

Mentions: All values of PFT in WP smokers were significantly lower than those of non-smokers (P < 0.05 to P < 0.001) [Figure 2].
