Implementing Prevention against Tobacco Dependence (PAD) "Toward the Tobacco-Free Schools, Neighborhoods, and Cities": Study Protocol.

INTRODUCTION: Although tobacco consumption in Iran has decreased in recent years, in 2010, the exposure to cigarette smoke was the fifth leading risk factor for death in Iran. This article is presenting the protocol for the prevention against tobacco dependence (PAD) project, an initiative planned and implemented by the Iranian Anti-Tobacco Association (IATA) of Iran in the city of Varamin. STUDY DESIGN: A prospective cohort study. METHODS: This project is carried out based on a participatory community-oriented approach and an action research method. It includes four inter-related, prospective studies phases; pilot, tobacco-free school (TFS), tobacco-free neighborhood (TFN), and tobacco-free city (TFS). The measuring tools for each phase were designed primarily using CDC and WHO guidelines and preliminary details were identified. Each phase is a combination of different methods (including systematic observation, questionnaire, heuristic interview, and structured interview). The studies will examine twelve goals and meet 9 project objectives in a comprehensive evaluation of ongoing progress with TFS, TFN, and TFC. DISCUSSION: This project seeks to achieve indicators of tobacco-free schools, neighborhoods, and cities through direct and indirect education of all the target groups in the community. Participation of stakeholders and supporters in problem-solving can increase the effectiveness and influence of the project. The outcomes of the first two phases will be expanded to the wider settings.

Prevalence of smoking and its association with health-related behaviours among Iranian university students: a large-scale study.

BACKGROUND: The prevalence of smoking and contributing factors among Iranian university students has been paid little attention. AIMS: The aim of this study was to assess the prevalence of smoking in Iranian university students and its association with health-related behaviours. METHODS: This cross-sectional study was carried out on a sample of 82 806 Iranian university students admitted in 2012-2013. Information on demographic characteristics and health-related behaviours, including physical activity, sleep pattern, use of electronic devices and dietary habits, were collected using a standardized questionnaire. Weight and height were measured using a standard protocol and body mass index calculated. Smokers were defined as students who smoked ≥ 1 cigarette per week. RESULTS: Smoking was prevalent among 6.0% of university students (males 6.6%, females 5.6%). Moderate physical activity was inversely associated with odds of smoking. A significant positive association was also found between obesity and odds of being a smoker. Higher intake of fruits and dairy products were associated with lower odds of smoking. However, intake of vegetables, fast foods and carbonated beverages was positively associated with smoking. Breakfast consumption was also associated with greater odds of being a smoker. CONCLUSIONS: Demographic characteristics and health-related behaviours, including marital status, occupation, economic status, sleep pattern, physical activity, use of electronic devices and dietary intake, were significantly associated with smoking.

Air pollutants associated with smoking in indoor/outdoor of waterpipe cafés in Tehran, Iran: Concentrations, affecting factors and health risk assessment.

Despite increasingly growth in waterpipe smoking in Tehran, so far no study has been conducted on the air quality of the waterpipe and cigarette cafés. Thirty-six cafés were selected and the concentration of three pollutants including formaldehyde, carbon monoxide and nicotine were measured in both indoor and outdoor air of cafés two times (week-day and weekend's session). Air sampling was performed for 180 min for each pollutant. It was observed that the concentration of pollutants inside the cafés was higher during weekend session (with a higher number of "active waterpipe heads") compared with findings during the week-day sessions. Furthermore, the concentration of pollutants in the indoor air of the cafés was significantly higher than that of the outdoors (p < 0.05). According to path analysis, the number of "active waterpipe heads" had the maximum impact on generation of pollutants inside the cafés, followed by the type of tobacco as the second influential factor. The average of lifetime cancer risk (LTCR) resulted by formaldehyde exposure through inhalation in waterpipe (WS), cigarette (CS), waterpipe and cigarette (WCS) and none-smoking (NS) cafés in week-day and weekend sessions were estimated to be 111 × 10-5 and 61.2 × 10-5, 33.7 × 10-5 and 39.4 × 10-5, 271 × 10-5 and 322 × 10-5, and 4.80 × 10-5 and 5.90 × 10-5, respectively, which exceed the limit value by the U.S.EPA and WHO. The concentration of pollutants in the indoor air of smoking cafés in Tehran is significantly high, such that it can pose serious risks for the health of both personnel and customers. Therefore, decision makers are expected to enact applicable and strict policies so as to abate this public health risk.
