Prevalence and correlates of smoking on the roof of the world

Determinant factors of tobacco use among ever-married men in Bangladesh

Background

The burden of tobacco use is shifting from developed to developing countries. This study aimed to explore the different types of tobacco use, and to identify the determinant factors associated with the tobacco use among ever-married men in Bangladesh.

Data and methods

Data of 3,771 ever-married men, 15–54 years of age were extracted from the Bangladesh Demographic and Health Survey 2007. Prevalence rate, chi-square (χ²) test, and binary logistic regression analysis were used as the statistical tools to analyze the data.

Results

Tobacco use through smoking (58.68%) was found to be higher than that of chewing (21.63%) among men, which was significantly more prevalent among the poorest, less educated, and businessmen. In bivariate analysis, all the socioeconomic factors were found significantly associated with tobacco use; while in multivariate analysis, age, education, wealth index, and occupation were identified as the significant predictors.

Conclusion

Tobacco use was found to be remarkably common among males in Bangladesh. The high prevalence of tobacco use suggests that there is an urgent need for developing intervention plans to address this major public health problem in Bangladesh.

Quit smoking for life--social marketing strategy for youth: a case for Pakistan

Smoking is the single most avoidable risk factor for cancers. Majority of smokers know about this fact but it is difficult for them to give it up mainly in the face of widespread smoking advertisements by the tobacco industries. To reduce the prevalence of smoking and its associated cancers, immediate actions are required by public health authorities. Social marketing is an effective strategy to promote healthy attitudes and influence people to make real, sustained health behavior change by transiting through different stages which include precontemplation, contemplation, preparation, action, and maintenance. Social marketing can influence smokers to voluntarily accept, reject, modify, or abandon their smoking behavior. In Pakistan, the smoking prevalence has been increasing, necessitating effective measures. The trend of its usage has been going upwards and, according to the World Health Organization, in Pakistan, the usage of cigarette smoking is increased by 30% compared to 1998 figures. The Pakistan Pediatrics Association has estimated 1,000 to 1,200 school-going children between the ages of 6 and 16 years take up smoking every day. In Pakistan, ex-smokers in the low socioeconomic group reported spending 25% of the total household income on this habit. This paper focuses on the antismoking social marketing strategy in Pakistan with an aim to reduce smoking prevalence, especially among the youth.

Tobacco use among the elderly: a systematic review and meta-analysis

The aim of this study was to combine the results of identified surveys on the prevalence of tobacco use in old age to estimate world prevalence of tobacco use and possible factors related to such behavior among the elderly. The literature search included electronic databases such as MEDLINE, LILACS, and Biological Abstracts, hand-searching of specialist journals and cited reference searches. The combined global prevalence was estimated using the random effects model. The total number of elderly subjects included in all surveys was 140,058, with data available from all the continents. Overall prevalence of tobacco use was 13% in both genders (22% male and 8% female). The prevalence rates were heterogeneous among surveys and were associated with smoking definition, questionnaire application, and country economic status. Few epidemiological studies assessed tobacco use among the elderly. A higher prevalence rate of tobacco use in males who live in higher income countries could be found, although additional evidence regarding elderly samples is still required.

Body mass index associated with elevated blood pressure in Mexican school-aged adolescents

OBJECTIVE

To evaluate the relationship between blood pressure and body mass index among adolescents.

METHODS

A 14-month period cross-sectional study was carried out among 2387 adolescents attending public schools in the state of Morelos, Mexico between 2005 and 2007. We measured blood pressure during four visits, obtaining elevated blood pressure prevalence according to the guidelines for children and adolescents of the United States National Educational Program on High Blood Pressure (at least three visits needed to assess elevated blood pressure on the basis of 95th percentile specific for gender, age and height). We used specific body mass index percentiles for age and gender. We employed multiple linear and Cox proportional hazards models to identify factors related to elevated blood pressure.

RESULTS

The overall prevalence of elevated blood pressure was 3.9%. Multiple linear models showed that overweight subjects had systolic and diastolic blood pressures that were 5.1 and 2.5 mmHg higher, respectively, compared with adolescents with a normal body mass index, while obese subjects had 11.3 and 6.2 mmHg higher levels, respectively. Cox proportional hazards models indicated high risk of elevated blood pressure among overweight (RR, 3.6; 95%CI, 1.5-8.5) and obese subjects (RR, 14.2; 95%CI, 7.2-27.75) compared with adolescents with a normal body mass index.

CONCLUSION

Our results suggest that a higher body mass index is associated with elevated systolic and diastolic blood pressure levels, indicating the importance of incorporating strategies for ongoing screening and for promoting educational programs on healthy lifestyles to prevent hypertension in adolescents.

Prevalence and correlates of smoking among urban adult men in Bangladesh: slum versus non-slum comparison

BACKGROUND

Smoking is one of the leading causes of premature death particularly in developing countries. The prevalence of smoking is high among the general male population in Bangladesh. Unfortunately smoking information including correlates of smoking in the cities especially in the urban slums is very scarce, although urbanization is rapid in Bangladesh and slums are growing quickly in its major cities. Therefore this study reported prevalences of cigarette and bidi smoking and their correlates separately by urban slums and non-slums in Bangladesh.

METHODS

We used secondary data which was collected by the 2006 Urban Health Survey. The data were representative for the urban areas in Bangladesh. Both slums and non-slums located in the six City Corporations were considered. Slums in the cities were identified by two steps, first by using the satellite images and secondly by ground truthing. At the next stage, several clusters of households were selected by using proportional sampling. Then from each of the selected clusters, about 25 households were randomly selected. Information of a total of 12,155 adult men, aged 15-59 years, was analyzed by stratifying them into slum (= 6,488) and non-slum (= 5,667) groups. Simple frequency, bivariable and multivariable logistic regression analyses were performed using SPSS.

RESULTS

Overall smoking prevalence for the total sample was 53.6% with significantly higher prevalences among men in slums (59.8%) than non-slums (46.4%). Respondents living in slums reported a significantly (P < 0.001) higher prevalence of smoking cigarettes (53.3%) as compared to those living in non-slums (44.6%). A similar pattern was found for bidis (slums = 11.4% and non-slums = 3.2%, P < 0.001). Multivariable logistic regression revealed significantly higher odds ratio (OR) of smoking cigarettes (OR = 1.12, 95% CI = 1.03-1.22), bidis (OR = 1.90, 95% CI = 1.58-2.29) and any of the two (OR = 1.23, 95% CI = 1.13-1.34) among men living in slums as compared to those living in non-slums when controlled for age, division, education, marital status, religion, birth place and types of work. Division, education and types of work were the common significant correlates for both cigarette and bidi smoking in slums and non-slums by multivariable logistic regressions. Other significant correlates of smoking cigarettes were marital status (both areas), birth place (slums), and religion (non-slums). Similarly significant factors for smoking bidis were age (both areas), marital status (slums), religion (non-slums), and birth place (both areas).

CONCLUSION

The men living in the urban slums reported higher rates of smoking cigarettes and bidis as compared to men living in the urban non-slums. Some of the significant correlates of smoking e.g. education and division should be considered for prevention activities. Our findings clearly underscore the necessity of interventions and preventions by policy makers, public health experts and other stakeholders in slums because smoking was more prevalent in the slum communities with detrimental health sequelae.

Investigating socio-economic-demographic determinants of tobacco use in Rawalpindi, Pakistan

BACKGROUND

To investigate the socio-economic and demographic determinants of tobacco use in Rawalpindi, Pakistan.

METHODS

Cross sectional survey of households (population based) with 2018 respondent (1038 Rural; 980 Urban) was carried out in Rawalpindi (Pakistan) and included males and females 18-65 years of age. Main outcome measure was self reported daily tobacco use.

RESULTS

Overall 16.5% of the study population (33% men and 4.7% women) used tobacco on a daily basis. Modes of tobacco use included cigarette smoking (68.5%), oral tobacco (13.5%), hukka (12%) and cigarette smoking plus oral tobacco (6%). Among those not using tobacco products, 56% were exposed to Environmental tobacco smoke. The adjusted odds ratio of tobacco use for rural residence compared to urban residence was 1.49 (95% CI 1.1 2.0, p value 0.01) and being male as compared to female 12.6 (8.8 18.0, p value 0.001). Illiteracy was significantly associated with tobacco use. Population attributable percentage of tobacco use increases steadily as the gap between no formal Education and level of education widens.

CONCLUSION

There was a positive association between tobacco use and rural area of residence, male gender and low education levels. Low education could be a proxy for low awareness and consumer information on tobacco products. As Public health practitioners we should inform the general public especially the illiterate about the adverse health consequences of tobacco use. Counter advertisement for tobacco use, through mass media particularly radio and television, emphasizing the harmful effects of tobacco on human health is very much needed.

Tobacco use in the Dominican Republic: understanding the culture first

OBJECTIVE

To conduct formative research on the landscape of tobacco use to guide survey and subsequent intervention development in the Dominican Republic (DR).

DESIGN

Rapid Assessment Procedures, systematic qualitative methods (participant-observations, in-depth interviewing, focus groups) using bilingual mixed age and gendered teams from the United States and DR.

SUBJECTS

Over 160 adults (men and women), ages 18 to 90 years, current, former and never smokers, community members and leaders from six underserved, economically disadvantaged DR communities.

MAIN OUTCOME MEASURES

Key domains: tobacco use patterns and attitudes; factors affecting smoking initiation, continuation, quitting; perceived risks/benefits/effects of smoking; and awareness/effects of advertising/regulations.

RESULTS

Perceptions of prevalence varied widely. While "everybody" smokes, smokers or ex-smokers were sometimes difficult to find. Knowledge of health risks was limited to the newly mandated statement "Fumar es prejudicial para la salud" [Smoking is harmful to your health]. Smokers started due to parents, peers, learned lifestyle, fashion or as something to do. Smoking served as an escape, relaxation or diversion. Quit attempts relied on personal will, primarily for religious or medical reasons. Social smoking (custom or habit) (< 10 cigarettes per day) was viewed as a lifestyle choice rather than a vice or addiction. Out of respect, smokers selected where they smoked and around whom. Health care providers typically were reactive relative to tobacco cessation, focusing on individuals with smoking related conditions. Tobacco advertising was virtually ubiquitous. Anti-tobacco messages were effectively absent. Cultures of smoking and not smoking coexisted absent a culture of quitting.

CONCLUSIONS

Systematic qualitative methods provided pertinent information about tobacco attitudes and use to guide subsequent project steps. Integrating qualitative then quantitative research can be replicated in similar countries that lack empirical data on the cultural dimensions of tobacco use.

Assessing obesity and overweight in a high mountain Pakistani population

OBJECTIVES

To estimate the prevalence of obesity and overweight among adults in a high mountain rural population of Pakistan, and to determine the correlates of excess body weight. Design Cross-sectional study.

METHODS

A random sample of 4203 adults (aged 18 years and over) was selected by stratified random sampling from 16 villages in north Pakistan. Trained medical students measured height, weight and blood pressure. Trained interviewers obtained information from participants on sociodemographic variables, use of snuff, daily cigarette consumption, hypertension and family history of hypertension. Body mass index (BMI) calculated as kg/m(2) was used to define overweight (BMI > or = 25 kg/m(2)) and obesity (BMI > or = 30 kg/m(2)).

RESULTS

Using weight and height data available for 1391 men and 2754 women, mean BMI was 22.4 (95% CI 21.9, 22.9) for men and 22.6 (95% CI 21.9, 23.2) for women. The age-adjusted prevalence of BMI > or = 25 (overweight/obesity) was 13.5% for men and 14.1% for women. Overweight/obesity increased with age and the increase per year was identical for both men and women [adjusted odds ratio (AOR) = 1.01, 95% CI 1.01, 1.03]. Overweight/obese men and women were more likely to be hypertensive (men, AOR = 3.32, 95% CI 2.16, 5.09; women, AOR = 1.70, 95% CI 1.21, 2.39). Overweight/obese women were more likely to work in business or as skilled workers (AOR = 6.24, 95% CI 1.18, 32.83) while overweight/obese men were more likely to work as government employees (AOR = 2.59, 95% CI 1.66, 4.03). Family history of hypertension was a significant correlate of overweight/obesity in men (P value 0.004) and women (P value 0.000). Overweight/obese men and women were less likely to use smokeless tobacco (men, AOR = 0.65, 95% CI 0.43, 0.97; women, AOR = 0.54, 95% CI 0.35, 0.85).

CONCLUSION

The prevalence of risk factors for non-communicable diseases (NCDs) in Pakistan is expected to increase as further epidemiologic, nutritional and demographic changes occur. The assessment of excess body weight, and patterns and determinants of other risk factors for NCDs is important to provide useful guidelines in the planning of interventions to counter a growing problem.
