OBJECTIVETo evaluate the integrated effects of tobacco control programs through comparing the pre- and post-implementation of the Tianjin Tobacco Control Act (Act), in 4 successive years.

METHODSCase-related data on myocardial infarction was collected by Tianjin Surveillance System, New Case Registry. Both the representative sample size of indoor working places and public places for observation and PM2.5 monitored were selected through the calculation of Survey System, while the representative sample size of people involved in the survey for interview was under the Door to Door and Intercept.

RESULTSThrough comparing the pre- and post-implementation programs on Act, the posting of "No Smoking Sign" had become much more visible in hospitals, schools, governmental buildings and the waiting areas of public transportation. People smoked much less in the main public places, excepting for hotels and public bath rooms (P < 0.05). Exposure to secondhand smoking (SHS) had a 26.5% (P < 0.01) decline, than the Act was implemented in workplace and public place. Despite the number of cases increased in the entire population in Tianjin (β = -0.061, P = 0.00; β = 0.059, P = 0.00), cases with myocardial infarction presented at the hospitals were declining annually, among the indoor workers.

CONCLUSIONAct showed a positive effect in decreasing the number of smokers in public places thus protecting people from the negative effects on SHS. Message on health effect and social benefits on tobacco control should be disseminated to facilitate the comprehensive implementation of the Act.

INTRODUCTIONA local study completed in Singapore, which was part of an international multi-country study that aims to develop a global assessment of exposure to second-hand smoke in indoor workplaces, gathered data regarding the indoor air quality of public areas. It was hypothesised that air would be less polluted in non-smoking venues compared to places where smoking occurred.

MATERIALS AND METHODSA TSI SidePak AM510 Personal Aerosol Monitor was used to sample and record the levels of respirable suspended particles (RSP) in the air. A broad range of venues were sampled in Singapore. The primary goal of data analysis was to assess the difference in the average levels of RSP in smoke-free and non smoke-free venues. Data was assessed at 3 levels: (a) the mean RSP across all venues sampled compared with the mean levels of smoke-free and non smoke-free venues, (b) levels in venues where smoking occurred compared with similar venues in Ireland, and (c) comparison between smoke-free and non smoke-free areas according to the type of venue. Statistical significance was assessed using the Mann-Whitney U-test.

RESULTSThe level of indoor air pollution was 96% lower in smoke-free venues compared to non smoke-free venues. Averaged across each type of venue, the lowest levels of indoor air pollution were found in restaurants (17 microg/m3) and the highest in bars (622 microg/m3); both well above the US EPA Air Quality Index hazardous level of >or=251 ug/m3.

CONCLUSIONSThis study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public areas dramatically reduce exposure and improve worker and patron health.

OBJECTIVES: The regulatory changes in Korea during the national economic crisis 10 years ago and in the current global recession were analyzed to understand the characteristics of deregulation in labor policies. METHODS: Data for this study were derived from the Korean government's official database for administrative regulations and a government document reporting deregulation. RESULTS: A great deal of business-friendly deregulation took place during both economic crises. Occupational health and safety were the main targets of deregulation in both periods, and the regulation of employment promotion and vocational training was preserved relatively intact. The sector having to do with working conditions and the on-site welfare of workers was also deregulated greatly during the former economic crisis, but not in the current global recession. CONCLUSIONS: Among the three main areas of labor policy, occupational health and safety was most vulnerable to the deregulation in economic crisis of Korea. A probable reason for this is that the impact of deregulation on the health and safety of workers would not be immediately disclosed after the policy change.

The management system of occupational diseases in Korea can be assessed from the perspective of a surveillance system. Workers' compensation insurance reports are used to produce official statistics on occupational diseases in Korea. National working conditions surveys are used to monitor the magnitude of work-related symptoms and signs in the labor force. A health examination program was introduced to detect occupational diseases through both selective and mass screening programs. The Working Environment Measurement Institution assesses workers' exposure to hazards in the workplace. Government regulates that the employer should do health examinations and working conditions measurement through contracted private agencies and following the Occupational Safety and Health Act. It is hoped that these institutions may be able to effectively detect and monitor occupational diseases and hazards in the workplace. In view of this, the occupational management system in Korea is well designed, except for the national survey system. In the future, national surveys for detection of hazards and ill-health outcomes in workers should be developed. The existing surveillance system for occupational disease can be improved by providing more refined information through statistical analysis of surveillance data.

OBJECTIVES: To evaluate the impact of the workplace smoking ban in South Korea, where the male smoking rate is high (57%), on smoking behavior and secondhand smoke exposure. METHODS: A workplace smoking ban legislation implemented in April 2003 requires offices, meeting rooms, and lobbies located in larger than 3,000 square meter buildings (or 2,000 square meter multipurpose buildings) should be smoke free. A representative cross-sectional survey, the third wave (2005) of health supplements in the National Health Nutrition Survey of South Korea, was used to measure the impact of the 2003 workplace smoking ban implementation on smoking behavior. It contained 3,122 observations of adults 20 to 65 years old (excluding self-employed and non-working populations). A multivariate statistical model was used. The self-reported workplace smoking ban policy (full workplace ban, partial workplace ban, and no workplace ban) was used as the key measure. RESULTS: A full workplace smoking ban reduced the current smoking rate by 6.4 percentage points among all workers and also decreased the average daily consumption among smokers by 3.7 cigarettes relative to no smoking ban. Secondhand smoke showed a dramatic decrease of 86 percent (= -1.74/2.03)from the sample mean for full workplace ban. However, public anti-smoking campaign did not show any significant impact on smoking behavior. CONCLUSIONS: The full workplace ban policy is effective in South Korea. Male group showed bigger impact of smoking ban policy than female group. The public antismoking campaign did not show any effectiveness.
