OBJECTIVETo assess the implementation of five key tobacco control policies in China: protection from second-hand smoke (SHS); offering help to quit; health warnings regarding tobacco use; the enforcement of bans on tobacco advertising, promotion, and sponsorship; and increasing tobacco taxes and prices.
METHODSUsing 2010 Global Adults Tobacco Survey in China (GATS-China), 10 indicators are used to assess the implementation of five key tobacco control policies of MPOWER in China.
RESULTSOverall, 63.3% and 72.7% of adults noticed people smoking indoor workplaces and public places, respectively. Approximately 60% of smokers were not asked about their smoking habits and approximately 67% were not advised to quit on their visit to a health worker. Sixty percent of adults noticed health warning messages on cigarette packaging and in the media in the last 30 days, 63.6% stated that they would not consider quitting. Twenty percent of respondents noticed tobacco advertising, promotion, and/or sponsorship activities in the 30 days prior to the survey. Among them, 76.3% noticed the direct advertising and 50% noticed from TV programs. Although purchasing price of one pack of cigarettes ranged from 1 to 200 RMB, 50% of current smokers (about 150 million) spent 5 RMB or less on one pack of cigarette. The expenditure on 100 packets of cigarettes represents 2% of 2009 GDP per capita.
CONCLUSIONThe average score for the implementation of the 5 policies of MPOWER in China is 37.3 points, indicating tobacco control policies in China is poor and there is a large gaps from the FCTC requirements.

Objective: To understand the prevalence and influencing factors of tobacco dependence among the population aged 15-69 in Tianjin to provide the basis for formulating targeted smoking control intervention policies and carrying out scientific smoking cessation intervention services. Methods: The data of this study comes from the 2018 Tianjin residents' health literacy monitoring survey. Probability-proportional-to-size sampling is adopted for sampling. SPSS 26.0 software was used for data cleaning and statistical analysis, and χ2 test and binary logistic regression were used to analyze the influencing factors. Results: A total of 14 641 subjects aged 15-69 were included in this study. After standardized, with a smoking rate of 25.5%, including 45.5% for men and 5.2% for women. Among the population aged 15-69, the prevalence of tobacco dependence was 10.7%; among current smokers, the prevalence rate of tobacco dependence is 40.1%, of which the prevalence rate of male tobacco dependence is 40.0%, and the prevalence rate of female tobacco dependence is 40.6%. According to multivariate logistic regression analysis, people who live in rural areas, have an education level of primary school or below, smoke every day, smoke the first cigarette ≤15 years old, smoke ≥21 cigarettes per day, and smoke for more than 20 packet years, people who report poor physical health are more likely to suffer from tobacco dependence (all P<0.05); age and smoking age did not affect the possibility of tobacco dependence (all P>0.05). Among current smokers, there was no significant difference in their willingness to quit smoking whether they had tobacco dependence (P>0.05). The proportion of people with tobacco dependence who have tried to quit smoking and failed is higher (P<0.001). Conclusions: The prevalence of tobacco dependence among smokers aged 15-69 in Tianjin is high, and the demand for quitting smoking is great. Therefore, smoking cessation publicity should be carried out for key groups, and smoking cessation intervention work in Tianjin should be continuously promoted.

BACKGROUND: This study evaluated the association between nicotine dependence and depressive mood in patients who visited a secondary hospital for smoking cessation treatment.METHODS: From March 2016 to February 2017, a total of 48 patients who visited the smoking cessation clinic of a secondary hospital in Seoul were surveyed through questionnaires. Nicotine dependence was assessed by the Fagerström Test for Nicotine Dependence. The Beck Depression Inventory (BDI) was used to assess depressive mood.RESULTS: The mean BDI score was positively associated with nicotine dependence (P=0.01). In multivariable logistic regression analysis, increasing BDI was associated with higher odds (1.21, 95% confidence interval; 1.02–1.44) of high nicotine dependence after adjusting for all confounding variables.CONCLUSION: Depressive mood was positively associated with nicotine dependence among patients who visited a smoking cessation clinic. Consideration of depressive mood in smoking cessation treatment may be helpful for smoking cessation among patients with a willingness to quit smoking.

OBJECTIVETo describe the prevalence of smoking, quitting smoke, and passive smoking in different populations by education status, occupation and geographic distribution.
METHODSSurveillance on risk behaviors in 145 disease surveillance points (DSP) was carried out in 2002 by multi-steps random sampling through questionnaires. 16,407 records had been completed with 16 056 used for analysis. Indicators as smoking, current smoking, average cigarettes smoked and the cost per day, etc., were calculated by weight on age proportions from the 2000 census.
RESULTSEver-smoking rates in males and females aged 15 and over were 66.0% and 3.1%, respectively with ever-smoking rate dropped 1.8% in whole population, but increased in people aged 15-24. The number of total smokers was about 350 million, 30 million more than that in 1996. There were no obvious geographic differences seen among male, but big difference was seen in female smokers. Higher smoking rates were seen in the northeast and northern parts of the country. Rate of quitting smoking was increasing, from 9.42% in 1996 to 11.5% in 2002, referring to an increase of 10 million quitters. However, the rate of no intention to quit among smokers was still very high--74%. The average cigarettes consumption per person-day was the same as that in 1996--14.8 cigarettes/day, which cost 2.73 RBM/day. The cost was various in different groups of population with a 15 times difference. The level of exposure for passive smokers was not improved. The prevalence of passive smoking in nonsmokers were 53% in 1996 and 52% in 2002. Knowledge on smoking and health condition in population had been greatly improved, but still poor in the western areas. 60% of the people claimed in supporting banning of smoking in public places, 45% supporting the banning of all cigarettes ads, but big difference was seen in different geographic areas.
CONCLUSIONThe prevalence of smoking in Chinese males had reached its peak, leveling but had not yet obvious dropped. Communication on the knowledge of harm in smoking remained weak since people did not understand or support the strategies on tobacco control, especially in the western areas. Data indicated that the prevalence of tobacco use would not decrease over in short period and the disease burden caused by tobacco use would still be heavy in the next 30-50 years. The government and public health authorities should develop effective tobacco control in no time to decrease disease burden caused by smoking and passive smoking.

7.The effect of smoke and alcohol abuse to voice.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2008;22(15):686-687
OBJECTIVE:
To explore parameters which can discriminate the voice of smoke and alcohol abuse and healthy voice by contrasting the voice parameters of two groups, and to study the pathogenic mechanism of the adverse effect of smoke and alcohol abuse to voice by the change of parameters.
METHOD:
Selecting 33 male subjects with smoke and alcohol abuse, and selecting other 33 healthy male subjects with no smoking and alcohol abuse and no ENT disease as control, randomly. Assessed by "vocal assessment", each subject was required to phonate /ae/ for 3 s, voice parameters including F0, Jitter, NNE and CQ were collected for multivariate analysis.
RESULT:
There were significant difference between smoke and alcohol abuse group and controlled group on the voice parameters (P < 0.01). F0 of the former is significantly lower than that of the latter (P < 0.01). Jitter of the former is significantly larger than that of the latter (P < 0.01). NNE of the former is significantly larger than that of the latter. CQ of the former is significantly smaller than that of the latter (P < 0.01).
CONCLUSION
Smoke and alcohol abuse had the adverse effect on the human voice. Both theory and experiment analysis were useful methods of selecting sensitive parameters. F0, Jitter, NNE and CQ were effect parameters which can reflect the voice characteristic of smoke and alcohol abuse, and can be used to monitor the effect of therapy for this kind of pathological voice.

OBJECTIVETo review the current evidence that links smoking to obstructive sleep apnea (OSA) and to discuss some potential mechanisms proposed for these links.
DATA SOURCESWe searched PubMed and Medline to identify studies investigating the interaction between smoking and OSA.
STUDY SELECTIONArticles regarding the relationship between smoking and OSA were selected. Studies considered smoking as a confounding factor were excluded.
RESULTSThe association of smoking and OSA has been confirmed in several studies. The effects of smoking on the pathophysiology of OSA may include smoking-induced upper airway inflammation, stimulant effects of nicotine on upper airway muscles, and a "rebound effect" due to nightly short-term nicotine withdrawal, or all of the above. In addition, the coexistence of OSA and smoking may have more widespread implications for cardiovascular dysfunction in patients with OSA. Finally, OSA might be responsible for the addiction to nicotine.
CONCLUSIONSSmoking may act as a risk factor for OSA and join with OSA in a common pathway to increase the risk of systematic injury. OSA, in turn, may be a predisposing factor for smoking. Thus, smoking cessation is recommended when considering treatment for OSA, and treating OSA may be a necessary precondition for successful smoking cessation.

INTRODUCTIONThis study assessed occupational differences in the prevalence of mental and physical disorders in an employed general population sample in Singapore and investigated the impact of these disorders on work productivity losses in terms of work-loss days and work-cutback days. The association of occupation with alcohol use disorders (AUD) and nicotine dependence (ND) was also investigated.
MATERIALS AND METHODSData from a population-based mental health survey of a representative sample of multi-ethnic residents aged 18 years and above were used. The World Health Organization's (WHO) Composite International Diagnostic Interview (CIDI) was administered to establish the lifetime diagnosis of key mental disorders. Self-report on sociodemographic characteristics, productivity loss, ND, and lifetime physical conditions were obtained. Nine occupational groups were included in this analysis.
RESULTSThe sample comprised 4361 participants with a mean (SD) age of 42.2 (11.9) years, ranging between 19 to 80 years. 'Associate professionals and technicians' (26.2%), 'Services and sales workers' (17.7%) and 'Professionals' (15.4%) were the 3 predominant occupational categories. Sociodemographic characteristics differed significantly across occupations (P <0.001). The lifetime prevalences of having 'any mental disorder' and 'any physical disorder' were 13.0% and 37.9%, respectively; major depressive disorder was the most prevalent mental disorder (5.9%) and hypertension was the most common physical disorder (15.6%). There were no significant differences in work productivity loss across occupations. Sociodemographic and occupational correlates for AUD and ND were identified.
CONCLUSIONSociodemographic and health disparities exist in the major occupational categories in Singapore. The strength of the associations between occupation and AUD and ND are significant, indicating the need for preventative measures in select occupations.

OBJECTIVETo determine the level of awareness of the hazards of tobacco smoking and secondhand smoke inhalation among adults in China.
METHODSHousehold surveys were conducted with a total of 13,354 respondents aged 15 years or over from 100 counties of 28 Chinese provinces using a stratified multi-stage geographically clustered sample design.
RESULTSThe findings revealed that 81.8% of the population was aware that smoking causes serious diseases, and 27.2% and 38.7% were aware that smoking causes stroke and heart attack, respectively. Only 64.3% of respondents were aware that secondhand smoke can cause serious diseases, and 27.5%, 51.0%, and 52.6% were aware that secondhand smoke causes heart disease in adults, lung disease in children and lung cancer in adults, respectively. Awareness regarding smoking-related hazards across all participants was significantly associated with several factors, including gender, smoking status, urban/rural residency, education level and exposure to tobacco control publicity in the last 30 days. Awareness regarding tobacco-related hazards in smokers was significantly associated with urban/rural residency, education level, exposure to tobacco control publicity in the last 30 days, and physician's advice. Awareness relating to the hazards of inhaling secondhand smoke was associated with smoking status, urban/rural residency, age, education level, and exposure to tobacco control publicity in the last 30 days. Medical professionals were found to know more about the health hazards of tobacco compared with people in other types of employment.
CONCLUSIONSOverall awareness of the health hazards of tobacco has improved in the last 15 years in China, but is still relatively poor. Improved means of communicating information and more effective warning labels on cigarette packaging are necessary for increasing public awareness of tobacco hazards, particularly among rural residents and people with less education.
