Is government action out‐of‐step with public opinion on tobacco control? Results of a New South Wales population survey

Objective: To assess community attitudes towards smoking bans, tobacco availability, promotion and product regulation, tobacco industry donations to political parties, and government spending on tobacco control activities. To compare public preferences on these issues with policies of the NSW and Commonwealth governments. Method: Anonymous, computer assisted telephone interviews of adults from randomly selected households in the NSW Electronic White Pages conducted in 2004. All subjects completed a core question set and subsequently, one of three sub‐sets. Results: Overall 49.1% of eligible subjects consented. Data from two sub‐samples containing 1,191 and 1,158 subjects are reported. Majority support existed for smoking bans in all six settings assessed: children's playgrounds (89%), sports stadia (77%), licensed premises (72%), outdoor dining (69%), beaches (55%) and motor vehicles carrying children (55%). Respondents nominated vastly higher tobacco control budgets than current levels of government expenditure. On a scale assessing support for tobacco control (maximum score = 13), the mean scores of both non‐smokers (10.4) and smokers (8.0) were high. Of seven variables tested, only two: living with a smoker and personal smoking status were independent predictors of having a high pro‐tobacco control score. Conclusion: There is strong community support for additional government regulation mandating smoke‐free provision and other counter tobacco measures. Implications: Continued advocacy campaigns are required to align government tobacco control agenda more closely with public preferences.     

Smoking Bans in the Home and Car: Do Those Who Really Need Them Have Them?

Background. This paper addresses the question of whether individuals who are most in need of household and car smoking bans, such as individuals with children living at home or who have many friends who smoke, are the ones who have them.Method. A representative sample of 6985 California adults ages 18 and older participated in telephone interviews.Results. Overall, 76% of adults report having home smoking bans and 66% have car smoking bans. Being a smoker or African American, not having children in the home, having more friends who smoke, and lower household income were associated with lower prevalence of both home and car smoking bans (P < 0.01). In multivariate analyses, nonsmokers were 7.9 (95% CI = 3.56, 17.31) times more likely to have a home smoking ban when none of their friends were smokers compared to when most of their friends were smokers. Among smokers, there was an interaction between having children at home and the proportion of friends who smoke. Only 27 to 55% of smokers had home smoking bans unless most of their friends were smokers, then the odds of having a ban were 6.1 (95% CI = 2.76, 13.68) times higher for smokers with children (67% with home bans) than for smokers without children at home (25% with home bans).Conclusions. Efforts to increase home and car smoking bans for nonsmokers who have friends who smoke and smokers with children living at home are needed.     

Socioeconomic differences in exposure to tobacco smoke pollution (TSP) in Bangladeshi households with children: findings from the International Tobacco Control (ITC) Bangladesh Survey

This study assessed the pattern of exposure to tobacco smoke pollution (TSP; also known as, secondhand smoke) in Bangladeshi households with children and examined the variations in household smoking restrictions and perception of risk for children's exposure to TSP by socioeconomic status. We interviewed 1,947 respondents from Bangladeshi households with children from the first wave (2009) of the International Tobacco Control (ITC) Bangladesh Survey. 43.5% of the respondents had complete smoking restrictions at home and 39.7% were very or extremely concerned about TSP risk to children's health. Participants with lower level of education were significantly less likely to be concerned about the risk of TSP exposure to children's health and less likely to adopt complete smoking restrictions at home. Logistic regression revealed that the predictors of concern for TSP exposure risk were educational attainment of 1 to 8 years (OR = 1.94) or 9 years or more (OR = 4.07) and being a smoker (OR = 0.24). The predictors of having complete household smoking restrictions were: urban residence (OR = 1.64), attaining education of 9 years or more (OR = 1.94), being a smoker (OR = 0.40) and being concerned about TSP exposure risk to children (OR = 3.25). The findings show that a high proportion of adults with children at home smoke tobacco at home and their perceptions of risk about TSP exposure to children's health were low. These behaviours were more prevalent among rural smokers who were illiterate. There is a need for targeted intervention, customized for low educated public, on TSP risk to children's health and tobacco control policy with specific focus on smoke-free home.     

Home Exposure to Secondhand Smoke among People Living in Multiunit Housing and Single Family Housing: a Study of California Adults, 2003–2012

Public health education efforts continue to encourage people to adopt voluntary smoking bans at home; nonetheless, the home remains a place where many people are exposed to secondhand smoke (SHS). Little is known about how SHS exposure in the home differs between adults residing in multiunit housing (MUH) and those residing in single family housing (SFH). This study (1) compared the socio-demographic characteristics, chronic disease conditions, and smoking status of adults living in MUH with those living in SFH, (2) assessed the correlates of living in MUH for adults, and (3) evaluated the association of residency in MUH and SFH with the odds of being exposed to SHS at home using population-based survey data of California adults. Smoking prevalence was significantly higher among MUH residents than SFH residents. The adjusted odds of exposure to SHS at home were 32 % higher for MUH smokers than SFH smokers but were not significantly different for non-smokers. This study presents evidence that there are significant socio-demographic differences between MUH residents and SFH residents and that MUH smokers have higher rates of exposure to SHS at home than SFH smokers after adjusting for other covariates. To reduce home exposure to SHS among MUH residents, it is important to adopt tobacco control policies that are aimed at reducing SHS exposure in and around MUH and at reducing cigarette smoking among current smokers in MUH.     

Children’s exposure to second‐hand smoke in the home: A household survey in the North of England

Exposure of children to second‐hand smoke (SHS) leads to increased risk of health and social problems and uptake of smoking in the future. We aimed to assess the prevalence of children’s exposure to SHS in their homes, in a deprived area in the North of England and identify what people thought would help them achieve a smoke‐free home (SFH). We performed a cross‐sectional survey of 318 households with at least one child aged under 16 years in Beeston Hill, a deprived locality in Leeds, England in June 2008. One hundred and seventy‐three households [54%, 95% confidence interval (C.I.) 49–60] had at least one smoker in the house. In 42% (95% C.I. 35–50) of these households (n = 73), smoking took place in the presence of children. The odds of allowing smoking in front of children were 2.2 (95% C.I. 1.1–4.5) times greater in households whose head had less than A‐level (national exams at 18 years) or equivalent qualification than in homes with a more qualified head of household. 92% of respondents were aware that SHS has negative effects on children’s health. However, 71% felt more information about health risks to children would help reduce exposure to SHS in the home. Smoking in the presence of children takes place in a relatively high proportion of households with smoker(s), despite media awareness campaigns regarding the dangers of passive smoking launched alongside the recently enforced smoke‐free public and workplaces legislation. Specific promotion of SFHs is needed to protect the health of children.     

Young adult perceptions of smoking in outdoor park areas

PurposeSmoking restrictions in recreational settings are established to promote anti-smoking norms and reduce exposure to secondhand smoke. Outdoor smoke-free policies are increasing, yet little is known about the perceptions of such restrictions.MethodsData were collected from a population-based sample of young adults (n=2289) in upper Midwestern United States. Cross-sectional multivariate logistic regression was used to assess predictors of the perceived difficulty to smoke in outdoor park areas.ResultsLiving in an area with a smoke-free park policy was associated with a 1.4 times higher odds of perceiving difficulty to smoke compared to those living in an area without such a policy, after controlling for past month smoking, physical activity, age, and gender. Both smokers and non-smokers living in an area with a smoke-free park policy had higher odds of perceiving difficulty to smoking in park areas (OR=1.6 and 1.3 respectively) compared to smokers and non-smokers living in areas without such policies.ConclusionBanning smoking in park areas was associated with a heightened perception of difficulty in smoking for young adult smokers and non-smokers.     

Tobacco use behaviors and household smoking bans among Chinese Americans

PURPOSE: To assess the relationship between household smoking restrictions and smoking patterns among Chinese American adults. DESIGN: This is a cross-sectional analysis based on a National Institutes of Health-funded population-based household and telephone survey of 2537 Chinese American adults. SETTING: Two communities in New York City. SUBJECTS: The analyses focused on male current smokers (N = 600). MEASURES: Demographic characteristics, smoking status, household smoking restrictions, cigarettes smoked per day, and past quit attempts were based on self-reported data. RESULTS: Among current smokers, 37% reported living in a home with a complete smoking ban. Smokers with a full household smoking ban smoked fewer cigarettes on weekdays and weekends than smokers with no household smoking ban (p < or = .05) and were 3.4 times (p < .01) more likely to report having at least one quit attempt in the past 12 months. Smokers with knowledge of the dangers of environmental tobacco smoke (ETS) exposure were 2.8 times (p < or = .01) more likely to have at least one quit attempt in the last 12 months compared with those who were unaware of the danger of ETS and more likely to live in a smoke-free household. CONCLUSIONS: Smoke-free home policies and interventions to raise awareness among smokers of the dangers of ETS have the potential to significantly reduce tobacco use and exposure to household ETS among this immigrant population.     

Electronic cigarette use in New South Wales,Australia: reasons for use,place of purchase and use in enclosed and outdoor places

Objective: To monitor patterns of use of e‐cigarettes to understand their potential impact on the New South Wales (NSW) population in Australia. Methods: A cross‐sectional online survey was carried out with a sample of adults in NSW in February 2016. Ever and past 30‐day use of e‐cigarettes, reasons for use, place of purchase and use within outdoor and enclosed public places were assessed along with sociodemographic characteristics. Results: Ever and past 30‐day use was reported by 13% and 4% of the sample, respectively. More than one‐third of participants did not purchase their own e‐cigarette (36.3%). The most frequently reported reason for using an e‐cigarette for smokers and ex‐smokers was to help quit smoking (45.3% and 44.7%, respectively) while for non‐smokers it was novelty (40%). E‐cigarettes were most commonly used at home (59.4%), in outdoor dining areas (36.8%) and in the workplace (27.8%). Conclusions: E‐cigarettes are being used by a small percentage of the NSW population. Reasons for e‐cigarette use varied with smoking status. Different sociodemographic characteristics were associated with ever and past 30‐day use of e‐cigarettes. E‐cigarettes are being used in areas that are covered by smoke‐free legislation. Implications for public health: Given e‐cigarettes are being used in smoke‐free areas, policy‐makers could take a precautionary approach by including e‐cigarette use under smoke‐free legislation.     

Effects of restaurant and bar smoking regulations on exposure to environmental tobacco smoke among Massachusetts adults

OBJECTIVES: We examined the association of local restaurant and bar regulations with self-reported exposure to environmental tobacco smoke among adults. METHODS: Data were derived from a telephone survey involving a random sample of Massachusetts households. RESULTS: Compared with adults from towns with no restaurant smoking restrictions, those from towns with strong regulations had more than twice the odds of reporting nonexposure to environmental tobacco smoke (odds ratio [OR]=2.74; 95% confidence interval [CI]=1.97, 3.80), and those from towns with some restrictions had 1.62 times the odds of reporting nonexposure (OR=1.62; 95% CI=1.29, 2.02). Bar smoking bans had even greater effects on exposure. CONCLUSIONS: Strong local clean indoor air regulations were associated with lower levels of reported exposure to environmental tobacco smoke in restaurants and bars.     

Letter – Community perceptions of smoking bans in NSW licensed venues

Environmental tobacco smoke increases the risk of lung cancer and coronary heart disease, as well as causing irritation to the eyes, nose and throat. In recent years it has become clear that the only way to protect non‐smokers from exposure to environmental tobacco smoke in indoor areas is by eliminating smoking in those areas. In 2004 the New South Wales (NSW) Government announced that smoking in the indoor areas of licensed premises would be phased out by July 2007. The reason for this decision was to protect workers and patrons in these venues from the detrimental health effects of prolonged exposure to environmental tobacco smoke. At the same time, NSW Health conducted a study to monitor community attitudes to the phased introduction of smoking bans in these venues between 2003 and 2007 to gauge public understanding and acceptance of the government action and inform policy roll out. In combination with other data these surveys provide a powerful tool for health policy development.     

Household smoking and respiratory disease in under-five children

Environmental tobacco smoke is an important respiratory tract irritant in young children. To identify factors associated with respiratory disease and determine the main source of smoking exposure in the household, a cross-sectional study of 2,037 children who were immunized in primary health care clinics was conducted (in a sample of 10 out of 38 clinics with 200 children each). Parents answered a questionnaire about children's birth, passive smoking, former and current respiratory morbidity, socio-demographic characteristics, and living conditions. Analysis was based on hierarchical logistic regression. Prevalence of respiratory symptoms was 59.9% for children who live with smokers. Asthma and bronchitis showed the strongest association with smoking. In multivariate logistic regression, the following variables remained associated with asthma/bronchitis: socioeconomic status (OR = 2.93; 95%CI: 1.57-5.45), maternal schooling (OR = 1.46; 95%CI: 1.08-1.98)] and occupation (OR = 1.68; 95%CI: 1.04-2.74), neighborhood (OR = 1.47; 95%CI: 1.06-2.02), child's age (OR = 3.38; 95%CI: 2.31-4.95) and sex (OR = 1.46; 95%CI: 1.09-1.94), breastfeeding (OR = 1.66; 95%CI: 1.15-2.40), and household smoking (OR = 1.58; 95%CI: 1.18-2.11). Children with lower socioeconomic status and exposed to household smoking showed increased risk of respiratory disease.     

An examination of smoking initiation rates by age: results from a large longitudinal study in New Zealand

Objective: Investigations of smoking initiation often focus on the experiences of children and youth. However, prevalence data from the Tobacco Use Surveys (TUS) and the New Zealand (NZ) census suggest substantial uptake of smoking occurs after 15 years of age, including among young adults aged 18–24 years. Identifying initiation rates is difficult using cross‐sectional prevalence data, particularly among older age groups, which are subject to cohort effects and where quitting and premature mortality reduce prevalence. We aimed to identify initiation rates using a prospective study design. Methods: The SoFIE‐Health longitudinal survey included 15,095 subjects aged 15 years or older who responded in the three years that include the health module: 2004/05, 2006/07 and 2008/09. We calculated the proportion of ‘never smokers’ who became regular smokers (initiation) by age at baseline. Results: Initiation between 2004/05 and 2008/09 was 14.2% for 15–17 year olds, 7.0% for 18–19 years, 3.1% for 20–24 years and 1.4% for 25–34 years, with low levels of initiation (<1.0%) among older age groups. Conclusions: There were strong age‐related gradients in smoking initiation. Substantial initiation occurs among older youth and young adults, but is rare after age 24. Implications: Efforts to prevent initiation of smoking should focus not only on adolescents but also on older youth and young adults.     

Household smoking behaviours and exposure to environmental tobacco smoke among infants: are current strategies effectively protecting our young?

Objective: To determine the prevalence of infant exposure to environmental tobacco smoke (ETS) among infants attending child health clinics in regional NSW; the association between such exposure and household smoking behaviours; and the factors associated with smoking restrictions in households with infants. Methods: Parents completed a computer‐based questionnaire and infant urine samples were collected. Information was obtained regarding the smoking behaviours of household members and samples were analysed for cotinine. Results: Twenty seven per cent of infants had detectable levels of cotinine. Infant ETS exposure was significantly associated with the smoking status of household members, absence of complete smoking bans in smoking households and having more than one smoker in the home. Smoking households were significantly less likely to have a complete smoking ban in place. Conclusions: This study suggests that a significant proportion of the population group most vulnerable to ETS were exposed. Implications: Future efforts to reduce children's exposure to ETS need to target cessation by smoking parents, and smoking bans in households of infants where parents are smokers if desired reductions in childhood ETS‐related illness are to be realised.     

Factors Associated with Prenatal Smoking Among Black Women in Eastern North Carolina

Objectives: The objective of this research was to explore prenatal smoking behaviors among Black women attending prenatal clinics. Despite the racial disparities in poor pregnancy outcomes, and the well-known association of smoking with harmful outcomes, little research has been conducted about prenatal smoking among Black women. Methods: Women were enrolled in the study and interviewed at the time of the first prenatal visit. The interview contained items to assess prenatal smoking and cessation, depressive symptoms, demographic factors, and beliefs about smoking. Reports of smoking cessation were verified using urinary cotinine. Results: The sample consisted of 811 Black women. Fourteen percent of the women were self-reported smokers, 12.6% reported cessation and 73% were nonsmokers. Twenty percent of the self-reported quitters had elevated cotinine; when these women were reclassified, 17% of the women were smokers. Factors associated with smoking in logistic regression analysis included elevated maternal depressive symptoms (OR = 1.7, 95% CI: 1.1–2.6), maternal age 20 years or older (OR = 1.94; 95% CI: 1.1, 3.3), less than a high school education (OR = 2.2; 95% CI: 1.2, 3.8), unmarried/not living with a partner (OR = 1.9; 95% CI: 1.0, 3.6), and allowing smoking in the home (OR = 5.5; 95% CI: 3.4, 8.6). Conclusions: The prevalence of maternal prenatal smoking was much higher among women in this sample than has been previously reported. The rate of nondisclosure of smoking among self-reported quitters was also high. Maternal behavioral (allowing smoking in the home) and psychosocial factors (depressive symptoms) were associated with prenatal smoking.     

Household smoking bans: which households have them and do they work?

BACKGROUND: This study characterized Oregon households according to type and degree of restrictions on smoking and explored whether smoking restrictions are associated with decreased environmental tobacco smoke (ETS) exposure. METHODS: A population-based, random-digit-dialed cross-sectional telephone survey of 6,199 adult Oregonians was performed in 1997 to provide baseline data on tobacco use in Oregon. RESULTS: Seventy percent of Oregon households were composed of nonsmokers only, and 85% of those had a full ban on smoking inside the home. Of the households containing one or more smokers, 38% had a full household ban on smoking. Among respondents with a full ban in place, 99% of nonsmoker-only households reported that no one smoked in the home in the previous month, compared with 91% of households with at least one smoker. In both nonsmoker-only households and those with at least one smoker, full bans were strongly associated with awareness of the harm of ETS (OR = 12.8, 95% CI 7.3-22.3, and OR = 6.6, 95% CI 3.6-12.3, respectively). The presence of children in the household was also closely associated with full bans in the two types of households (OR = 4.6, 95% CI 2.8-7.6, and OR = 3.0, 95% CI 2.1-4.4, respectively). Nevertheless, 50% of households with children and a smoker present did not have a full ban in place. CONCLUSIONS: While the prevalence of household smoking restrictions is high in Oregon, there remains room for improvement, since 50% of households with a smoker and a child present do not have a full ban on indoor smoking. Public health messages that focus on household smoking restrictions may help protect nonsmokers from exposure to ETS.     

Prevalence of tobacco use and associated factors among women in Paraná State, Brazil

This study aimed to estimate the prevalence of tobacco use and to describe the demographic profile of female smokers in Paraná State, Brazil. The study used a cross-sectional population-based design with cluster sampling (n = 2,153) of women 18 years or older in seven cities. Prevalence of smoking was 13.4%, ranging from 10% in Cascavel to 19% in Irati. According to multivariate analysis, city of residence, marital status, and schooling were significantly associated with tobacco use. Women in Irati (OR = 2.08; 95%CI: 1.22-3.54) were more likely to smoke than those in Cambé. Married women and widows were less likely to smoke (OR = 0.47; 95%CI: 0.30-0.73 and OR = 0.43; 95%CI: 0.22-0.87) than single women. Women living with a partner (but not married) were more likely to smoke than single women (OR = 2.49; 95%CI: 1.12-5.53), and women with university degrees were less likely to smoke than those with eight years of school or less (OR = 0.41; 95%CI: 0.22-0.87). The results confirm the need for tobacco control programs that take gender and regional differences into account.     

Environmental tobacco smoke in homes,motor vehicles and licensed premises: community attitudes and practices

OBJECTIVE: To assess community knowledge, attitudes and practices in relation to environmental tobacco smoke (ETS) especially in homes, private motor vehicles and licensed premises, and to document levels of support for further government legislation. METHODS: 656 persons aged 18 years and over, a sub-sample in a computer-assisted telephone survey of 2,087 randomly selected respondents across NSW, answered 12 ETS-specific questions. The whole sample was asked demographic, smoking status and household membership questions. The overall response rate was 61.4% (consent rate 75.4%). RESULTS: Overall, 32.8% (95% CI 27.8-37.8) of children aged 0-4 years in the households surveyed were reported to live with at least one smoker. Agreement about ETS hazards was lowest in relation to child ear problems (31.2%) and sudden infant death syndrome (50.6%). Complete bans on smoking were reported in 69.9% of homes and 77.1% of private motor vehicles. The percentages favouring total bans in homes (p < 0.001) and private motor vehicles (p < 0.001) were significantly lower among smokers than non-smokers. Overall, 55.8% supported legislation to ban smoking in private vehicles carrying children. The majority support restrictions on smoking in non-eating areas of licensed clubs (88.7%) and hotels (84.8%). Overall, the data indicate a ban on smoking in licensed premises is likely to increase business. CONCLUSION: Smoking is banned in most NSW homes and private motor vehicles. Acceptance of ETS risks is high but there are important knowledge gaps. Considerable support exists for further government regulation of ETS. Media campaigns are likely to reinforce a public environment already receptive of the need for more government ETS restrictions.     

Neighbourhood and individual socioeconomic inequalities in smoking: the role of physical neighbourhood stressors

OBJECTIVE: To explore the association between physical neighbourhood stressors and smoking, and the contribution of these stressors to neighbourhood and individual socioeconomic inequalities in smoking. METHODS: Data were analysed of participants of the baseline measurement of the Dutch GLOBE study (1991), aged 20 years and older, who lived in 79 neighbourhoods of the city of Eindhoven (n = 9062). The neighbourhood socioeconomic environment was assessed from aggregated self reported information of participants' education and occupation level, and employment status. Neighbourhood stressors included were the physical quality (decay), required police attention, noise pollution from traffic, and population density in neighbourhoods. Current smokers were distinguished from previous and never smokers. RESULTS: Compared with those living in the most advantaged neighbourhoods, residents living in the socioeconomically most disadvantaged neighbourhoods were more likely to smoke (adjusted for age, sex, education, occupation, and employment status) (OR = 1.24, 95% CI 1.05 to 1.46). An increase in a summary neighbourhood stressor score was associated with smoking, independently of the neighbourhood socioeconomic environment (OR = 1.57, 95% CI 1.11 to 2.21, in the neighbourhoods with the highest stress score). Adjustment for the score substantially reduced the odds ratio for living in the socioeconomic most disadvantaged neighbourhoods (OR = 1.03, 95% CI 0.84 to 1.28, for those in the most disadvantaged neighbourhoods). Neighbourhood stressors contributed 10% to the increased probability of smoking in the lowest educated persons. CONCLUSIONS: Physical neighbourhood stressors are related to smoking and contribute substantially to neighbourhood inequalities in smoking over and above individual level characteristics.     

Cigarette smoking behavior among US Latino men and women from different countries of origin

OBJECTIVES: This study sought to compare smoking behavior among Latino men and women from different countries of origin. METHODS: A telephone-administered survey was conducted in 8 cities with Latino men and women of different national origin living in census tracts with at least 70% Latino individuals. RESULTS: A total of 8882 participants completed the survey; 53% were women. The average age of respondents was 44 years; 63% were foreign-born, and 59% preferred Spanish for the interview. Current smoking was more prevalent among men (25.0%, 95% confidence interval [CI] = 23.7, 26.3) than among women (12.1%, 95% CI = 11.1, 13.0). Smoking rates were not significantly different by national origin among men, but Puerto Rican women had higher rates of smoking than other women. Central American men and women had the lowest smoking rates. Foreign-born respondents were less likely to be smokers (odds ratio [OR] = 0.77, 95% CI = 0.66, 0.90) than US-born respondents, and respondents with 12 years or less of education had an increased odds of smoking (OR = 1.17, 95% CI = 1.01, 1.35). High ac culturation was associated with more smoking in women (OR = 1.12, 95% CI = 1.00-1.25) and less smoking in men (OR = 0.86, 95% CI = 0.78-0.95). Puerto Rican and Cuban respondents were more likely to be current smokers and to smoke more than 20 cigarettes per day. CONCLUSIONS: Older, US-born, and more-educated respondents were less likely to be current smokers. Respondents of Puerto Rican and Cuban origin were more likely to smoke. Acculturation has divergent effects on smoking behavior by sex.     

综合评价法在明确中学生吸烟影响因素主导效应中的运用

目的了解深圳市光明新区中学生吸烟情况及影响因素的分布,并对特定人群进行分类,为针对性开展中学生吸烟干预提供依据.方法:运用分层整群抽样法对深圳市光明新区学校544名中学生进行吸烟状况,烟草有关知识,态度和行为,周围环境控烟情况等调查,SAS9.0软件进行分析.结果:深圳市光明新区中学生尝试吸烟率为15.1 %,吸烟率为3.13%.多因素非条件logistic回归分析:女性(OR=0.50, 95%CI:0.26~0.96)为尝试吸烟的保护性因素(P<0.001),好朋友吸烟(OR=1.88, 95%CI:1.08~3.27),具有好朋友给烟肯定会吸意愿(OR=3.11, 95%CI:2.12~4.54),年龄增加(OR=1.33, 95%CI:1.04~1.69)均增加了尝试吸烟的危险因素,CHAID法决策树分析显示,好朋友给烟肯定会吸和男性分别能对50.0%(41/82) 和36.6%( 30 /82) 的尝试吸烟者进行准确分类.尝试吸烟人群中,吸烟者与非吸烟者多因素非条件logistic回归分析,好朋友给烟肯定会吸(OR=8.38, 95%CI:2.27~30.93),父母未告诫不要吸烟(OR=12.29, 95%CI:1.21~34.73)是吸烟的危险因素,而认为吸烟会减少体重(OR=0.25, 95%CI:0.07~0.87)是保护因素;类平均法聚类分析显示,好朋友给烟是否会吸和父母是否告诫不要吸烟将吸烟者分为三类,其中为父母告诫不要吸烟但好朋友给烟会吸者占64.71%(11/17).结论:新区中学生吸烟状况比较严重,对影响尝试吸烟,吸烟的独立影响因素进行分类分析以确定特定因素及特定人群,而进行相应干预将更有助于提高新区中学生控烟效果.
