Public health problem of tobacco use
One of major preventable causes of death.Morbidity and mortality:Lung cancer, CVD, COPD, atherosclerosis.Over 4 millions die each year due to smoking 1 death due to smoking every 8 seconds
globally.
Economic impact on family:Smoking diverts money from basic needs. WHO, 2002

Situation in Armenia
Major public health problem, with a greater impact on urban areas.
Smoking rates among Armenian men one of the highest globally.
Smoking rates: male-60%, female-2% (age group -16 years and above), 2005.
National survey on Drug, Alcohol and smoking prevalence among general population of Armenia, 2005

Situation in India
Smoking is responsible for half of cancers in men and a quarter of cancers in women
WHO projects tobacco deaths may exceed 1.5 million by 2020 in India.
Smoking rates: male-57%, female-11% (age group -15 to 54 years), 2005-2006.
National Family Health Survey, India,2005-2006

Rationale for study
High smoking rates in Armenia and India.
No other comparative study conducted for these two countries
Finding common and different risk factors and protective factors associated with tobacco use between the two cities will inform and strengthen tobacco control programs.

DiscussionFemale students more likely to take up
regular smoking in New Delhi than in Yerevan
Regular smoking rates were higher in the earlier ages in New Delhi and were higher in later ages in Yerevan.
Rates of increase in smoking rates over age higher in Yerevan than Delhi.

20
DiscussionFathers almost twice as likely to be
smokers in Yerevan than in New Delhi.Students in Yerevan twenty times more
likely to accept and smoke a cigarette offered by their best friend than in New Delhi.
Anti-smoking references seen on posters and in newspapers and magazines were more frequently seen by non-regular smokers than regular smokers.

21
Limitations
There were too few girls who smoked to analyze them separately from boys
Because of lack of matches between the instruments, some questions were dropped out
![Page 22: Final Master Proj Presentation With Hyren Dp (1)](https://reader033.fdocuments.in/reader033/viewer/2022060118/5589a600d8b42ad43f8b4669/html5/thumbnails/22.jpg)
22
Strengths
Large sample size of New Delhi and adequate sample size of Yerevan
Surveys conducted only three year apart (2001 and 2004).
Surveys conducted prior to law banning tobacco advertising in both the cities.
![Page 23: Final Master Proj Presentation With Hyren Dp (1)](https://reader033.fdocuments.in/reader033/viewer/2022060118/5589a600d8b42ad43f8b4669/html5/thumbnails/23.jpg)
23
Conclusions
Smoking fathers and peer pressure are associated with increased risk of student smoking.
Family members discussing harmful effects of tobacco is substantially associated with reduced risk of smoking.
Unknown and unmeasured cultural and environmental factors different between the two cities associated with smoking
![Page 24: Final Master Proj Presentation With Hyren Dp (1)](https://reader033.fdocuments.in/reader033/viewer/2022060118/5589a600d8b42ad43f8b4669/html5/thumbnails/24.jpg)
24
RecommendationsSmoking fathers and peer pressure in Armenia
should be especially targeted for more effective anti-tobacco campaign
Family members included in anti-smoking programs to prepare them to discuss harmful effects of smoking.
More comparative studies needed to further explore unknown and unmeasured cultural/environmental factors.
