Differences in health and religious beliefs about tobacco use among waterpipe users in the rural male population of Egypt.

Waterpipe use is a highly prevalent form of tobacco use in the Eastern Mediterranean Region that is rooted in long-held cultural traditions that predate the use of cigarettes and present a particular challenge for tobacco control efforts. We did a stratified sampling of 4,994 Egyptian men from rural households of Egypt in order to conduct an interviewer-administered prevalence survey to identify differences in attitudes and beliefs toward smoking and smoking cessation between waterpipe users, cigarette smokers, mixed users (cigarette + waterpipe), and non-smokers. We found that cigarette smokers, mixed users, and/or non-smokers were (1) two- to ninefold more likely to believe that smoking decreased adult life expectancy and harmed a fetus than waterpipe users, (2) significantly more likely to believe that smoking is a sin ("haram") than were waterpipe users. Among tobacco users, we found that cigarette smokers and/or mixed users were significantly more likely to indicate pre-contemplation, contemplation, or intention to quit tobacco than waterpipe users. Our findings from rural Egyptian men indicate that waterpipe users are distinct from cigarette smokers in their perception that their form of tobacco use is less harmful and/or less subject to religious proscription. These beliefs may explain why waterpipe users seem less inclined to quit their tobacco habit and need to be considered in the design of tobacco cessation and prevention methods in Egypt and the region.

Waterpipe Smoking And The DRD2/ANKK1 Genotype.

BACKGROUND: Waterpipe smoking is increasingly a worldwide phenomenon. Few studies have been conducted on the epidemiology of waterpipe smoking behavior and its genetic determinants. A polymorphism (TaqI) in the 3' untranslated region of the dopamine receptor gene (DRD2), later localized to the neighboring ANKK1 gene, has been previously linked to cigarette smoking. Since all tobacco products share the ability of stimulating the dopaminergic reward system, variation in the DRD2 genotype might be associated with waterpipe smoking addiction. AIM: This study aims to explore genetic variations in DRD2 gene and waterpipe smoking, motives and addiction in Egyptian rural males. MATERIAL AND METHODS: The subjects (N=154) were selected from participants in a household smoking prevalence survey if they were adults, males, currently smoking waterpipe and not smoking cigarettes. Participants were interviewed about their smoking behaviors. Blood samples were genotyped by polymerase chain reaction (PCR). Subjects were subsequently classified as either the A1 (presence of at least one A1 allele) or A2 group (A2 homozygotes). RESULTS: The prevalence of A1 genotype was 34.4 % in current waterpipe users, and was associated with the maximum duration before smokers experienced craving to smoke: after adjusting for age of smoking initiation, smoking for addictive motives, and average daily tobacco consumption, the A1 carriers were more likely to experience craving within a shorter duration after abstinence (the first 24 hours) compared to subjects with A2/A2 genotype (Odds ratio [OR] 2.70, 95% confidence interval [CI]: 1.18 - 6.23). In addition, the frequent visitors of shisha cafes were more likely to be younger, heavy smokers and carriers of A1 allele (OR, 2.52, 95% CI: 1.06-6.02). CONCLUSION AND RECOMMENDATIONS: This study revealed that the maximum duration before experiencing craving to smoke waterpipe and frequency of visiting cafés to smoke may be influenced by an inherited variations in the DRD2 genotype.

Nondaily, light daily, and moderate-to-heavy cigarette smokers in a rural area of Egypt: a population-based survey.

INTRODUCTION: Understanding tobacco use among nondaily and light daily cigarette smokers is needed because they are dissimilar from other smokers and may require specific prevention efforts. METHOD: We compared three groups of adult male smokers in rural Egypt: light daily and nondaily smokers versus moderate-to-heavy daily smokers. Data were obtained from a household survey in 2003 in six randomly selected villages in the Nile Delta region of Egypt. There were 7,657 adult participants, of whom 48.6% were male and 51.4% were female. Among them, 1,401 males (37.6%) and 5 females (0.1%) were self-identified as current cigarette smokers; further analysis focused on males. We restricted data analysis to those who reported a stable pattern of 3+ years of smoking. There were 42 nondaily smokers. Daily smokers were subdivided into two groups: light daily smokers (who smoked no more than 10 cigarettes/day; n = 223) and moderate-to-heavy daily smokers (who smoked at least 11 cigarettes/day; n = 769). RESULTS: We found statistically significant differences between these groups on nearly every measure: nondaily smokers tended to be younger and unmarried, but they also had higher levels of education and professional occupations compared with the other smokers. Nondaily and the light daily smokers were more likely than moderate-to-heavy smokers to be planning to quit and to have self-efficacy for quitting, and they were less likely to be smoking in the presence of their wife and children at home. DISCUSSION: Further understanding of nondaily and light daily smokers may aid in tailoring specific interventions.

Genotoxic effects of waterpipe smoking on the buccal mucosa cells.

Waterpipe smoking is popular in many parts of the world. Micronuclei (MN) evaluation in the exfoliated oral cells of smokers is a non-invasive technique for evaluation of possible tobacco harm. We aimed to assess whether MN levels are higher in waterpipe smokers than in never smokers. We examined oral smears of 128 adult male waterpipe smokers and 78 males who never smoked tobacco in rural Egypt. The total number of MN per 1000 cells per subject, and the number of MN-containing cells per individual were compared. We observed a higher level of total MN in waterpipe smokers (10 +/- 4) than in never smokers (4 +/- 2, p < 0.001). A similar difference was found for the mean number of affected cells per individual (8 +/- 3 vs. 4 +/- 1.62, p < 0.001). MN levels were not significantly dose related. This study is among the first to assess the association between waterpipe smoking and a cytogenetic measure of tobacco harm. The twofold increase in MN level is consistent with previous reports of MN in cigarette smokers. More research is needed to determine if such MN levels are predictive of future health consequences.

Body mass index and up-to-date colorectal cancer screening among Marylanders aged 50 years and older.

INTRODUCTION: Overweight and obese individuals are at increased risk for developing and dying from colorectal cancer. Studies suggest that overweight and obese women are more likely to avoid or delay cancer screening. Our objective was to determine whether overweight or obese adults aged 50 years and older living in Maryland in 2002 were less likely to be up-to-date with colorectal cancer screening than normal and underweight adults. METHODS: The relationship between body mass index and colorectal cancer screening was evaluated based on responses from 3436 participants aged 50 years and older to the Maryland Cancer Survey 2002, a population-based random-digit-dial telephone survey. The survey contains self-reported information on colorectal cancer screening, height, weight, and potential confounders. Logistic regression was performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for age, sex, race, employment, marital status, education, area of residence, and health-care-related variables. RESULTS: Overall, 64.9% of Marylanders aged 50 and older were up-to-date with colorectal cancer screening. Compared with normal and underweight individuals, overweight individuals had similar odds of being up-to-date with colorectal cancer screening (OR, 1.05; 95% CI, 0.83-1.33). Obese individuals had slightly lower odds, but this difference was not statistically significant (OR, 0.84; 95% CI, 0.65-1.09). Recommendation by a health care provider for colorectal cancer screening was strongly associated with up-to-date colorectal cancer screening (OR, 36.7; 95% CI, 28.7-47.0). CONCLUSION: Our study shows no statistically significant association between body mass index levels and up-to-date colorectal cancer screening. We recommend that physicians and other health care providers increase up-to-date colorectal cancer screening rates in the population by referring their patients for appropriate screening.

Evaluation of Papanicolaou stain for studying micronuclei in buccal cells under field conditions.

OBJECTIVE: To compare Papanicolaou (Pap) and May-Grünwald Giemsa (MGG) stain as 2 techniques for staining for buccal mucosal cells to detect micronuclei (MN) infield studies. STUDY DESIGN: Eighty cytologic smears (2 per individual) were taken from the buccal mucosa of 40 cigarette smokers recruited at a rural village in Egypt. Forty smears were stained with Pap stain and 40 with MGG stain. All were assessed for cellularity and scored for MN. RESULTS: Pap stain was faster and easier to process and transport in the field study than was MGG stain. Regarding MGG smears, bacteria and cell debris masked the MN as compared to Pap smears, in which the fixative destroyed the bacteria and made the cell boundaries clearly demarcated. Using Pap stain, MN were seen easily in transparent cytoplasm. CONCLUSION: Pap stain is the preferred method infield studies for scoring and detecting MN in cells of buccal mucosa.

Comparison of cigarette and water pipe smoking among female university students in Egypt.

This study investigated behavioral and sociodemographic factors associated with tobacco use among female university students patronizing water pipe cafes in Cairo, Egypt. We interviewed two groups of female university student smokers (100 and 96 students from a public and a private university, respectively). The interviews took place in nine water pipe cafes near the two universities. A logistic regression model was developed to analyze the relationship between tobacco-related knowledge and beliefs and the choice between smoking water pipe or cigarettes. Among these smokers, 27% smoked cigarettes only, 37.8% smoked water pipe only, and 35.2% smoked both types of tobacco. Most of the water pipe smokers (74.1%) preferred this method because they believe it to be less harmful than smoking cigarettes. More than half of the subjects were encouraged to start smoking by other females (56.6%). Curiosity was a significant factor for initiation (OR = 2.8, 95% CI = 1.3-6.2, p<.01). We found no significant differences between water pipe and cigarette smokers regarding current age, age at initiation, quit attempts, knowledge about the hazards of smoking, wanting to be fashionable, or smoking with friends. About one in four (23.7%) attempted to quit, with health cited as a major reason. An urgent need exists for correction of the misperception among this study population that water pipe smoking is safe and less harmful than cigarette smoking.

DRD2/ANKK1 TaqI polymorphism and smoking behavior of Egyptian male cigarette smokers.

Little is known about the genetic contribution to cigarette smoking and nicotine addiction in Egypt. The dopamine D2 receptor gene contains a TaqI repeat fragment length polymorphism creating two alleles with functional significance, DRD2*A1 and DRD2*A2. We investigated the relationship between these alleles and tobacco use in a study of 389 Egyptian male current smokers (mean age = 40 years; SD = 12). Participants were interviewed in 2004 on their smoking behaviors and quit attempts, and were given the Fagerström Test for Nicotine Dependence (FTND). Blood samples were obtained and genotyped for DRD2 A1and A2 alleles. The frequencies of A1/A2, A1/A2, and A2/A2 genotypes were 6%, 29%, and 65%, respectively. We found no statistically significant association between genotype and age at onset of smoking, years of smoking, FTND score, or average number of cigarettes smoked per day. DRD2 genotype was associated with the number of cigarettes smoked in the past 48 hr (42.2 in A1 carriers vs. 37.6 in A2, p = .03), the previous quit duration (28% in A1 vs. 40% in A2 quit for more than 1 month, p = .05), and the depth of inhalation (82% in A1 vs. 72% in A2 inhaled the smoke deeply, p = .03). Logistic regression analysis including DRD2 genotype, FTND score, age at smoking initiation, marital status, and education as predictors showed that maximum duration of quit time was associated with FTND score (p = .003), DRD2 genotype (p = .01), marital status (p = .03), and age at smoking initiation (p = .04). These findings suggest a modest association between DRD2 genotype and quitting behavior in male cigarette smokers in Egypt.

Oral cancer exams among cigarette smokers in Maryland.

BACKGROUND: Current and former smokers are at increased risk to develop oral cancer. This analysis was performed to determine whether current and former smokers are more likely to undergo an exam for oral cancer than non-smokers. METHODS: The Maryland Cancer Survey performed in 2002 was a population-based random digit dial, statewide survey on cancer screening and risk behaviors, targeting adults aged 40 years and older. The dataset contains self-reported information on oral cancer examinations, current smoking status, and health care access information for 4840 Maryland residents. RESULTS: 2062 (42.6%) of Marylanders aged 40 years and older reported ever having had an oral cancer examination. Dentists and dental hygienists performed 90.9% of the exams. Current and former smokers were no more likely than those who have never smoked to have ever had the examination (adjusted OR = 1.02, 95% CI = 0.85-1.23 and OR = 1.09, 95% CI = 0.94-1.25, respectively). Other predictors associated with having an oral cancer exam included having more than a high school of education, being female, non-black, being in good to excellent health, and having a recent physical exam. Having visited the dentist in the last year had the highest odds of having ever had an oral cancer exam. CONCLUSIONS: Current and former smokers are a high-risk group who need to be targeted for oral cancer exams by dental professionals and primary care physicians.

Smoking prevention and treatment in Egypt.

The basic ingredients for a successful prevention program for Egypt are all present but to be successful, these efforts need to be maintained year round with additional resources for prevention and treatment made available to reach out to all regions and neighborhoods in Egypt. We need to expand our treatment capabilities by training primary care physicians to be more active in the area of smoking prevention and treatment.

Egyptian Smoking Prevention Research Institue (ESPRI).

The overall goal of the ESPRI is to reduce tobacco use in Egypt by carrying out interlocking observational, intervention and policy research, and through capacity building for research, prevention, communications and policy on smoking prevention. Having the ability to rely on ESPRI for the best scientific knowledge will add momentum to the current efforts underway to curb smoking in Egypt.

Review on water pipe smoking.

Water-pipe smoking may lead to cancers, genetic damage, diseases of the lungs and other disease conditions. Many of the studies on these subjects are merely anecdotal or lack the necessary rigorous study design or the power needed to be certain of the results. Given the large number of people who smoke waterpipe and the fact that waterpipe smoking has become a fashionable trend in the Middle East and the Western world among the youth, it is essential to study the health effects of waterpipe smoking with renewed emphasis.

Water pipe (Sisha) smoking in cafes in Egypt.

Shisha café patrons in Cairo, Egypt were interviewed to assess their knowledge, attitudes and practices regarding smoking and health. The median age of initiation of Shisha smoking is 20 years. Shisha smokers know about the hazards of smoking and believe that Shisha smoking is less dangerous than cigarette smoking. Over half the Shisha smokers have tried to quit in the past year. The younger adults who smoke Shisha also tend to smoke more often with friends, smoke cigarettes in addition to Shisha and prefer fruit flavored tobacco as compared to tobacco mixed with molasses favored by Shisha smokers who are older. Heavy Shisha smoking was not related to age.

Impact of religious rulings (Fatwa) on smoking.

An interview survey was carried out in a rural village and two nearby schools in Qalyubia Governorate to assess the pattern of smoking and knowledge about religious ruling (Fatwa) and its impact on the quit attempts. Also, a similar survey was conducted in 6 Shisha cafés in Cairo. The results showed that the majority of respondents (81% among rural adults, 83.2% among Shisha café patrons, 73.3% among rural youth and 81.4% among rural students) knew about the Fatwa on smoking. Higher proportions of all participants thought that smoking is a sin (97.3% among rural adults, 80.8% among Shisha café patrons, 94.4% among rural youth and 98.4% among rural students). There was a significantly higher knowledge about Fatwa on smoking among men than women. This indicates a successful outreach program targeted mainly to men through mosques. Knowledge about Fatwa on smoking increased significantly with increased exposure to antismoking messages from religious leader. Knowledge about the Fatwa on smoking or belief that smoking is a sin had no significant effect on quit attempts. Our results point to the need for intensive efforts on the part of religious leaders to translate the current belief that smoking is a sin into quitting among smokers. Better results may be achieved through personal interactions in small groups rather than in mosque settings.

Nicotine dependance among adult male smokers in rural Egypt.

Nicotine dependence is a significant public health problem. This study describes the nicotine dependence status among male adults in rural communities in Egypt. A survey was carried out in five rural villages in Egypt to study the smoking prevalence. A total of 938 current smokers were identified and their nicotine dependence status was studied. About 9% of all smokers in the studied villages were found to have heavy dependence to nicotine. Heavy dependence was associated with younger age of smoking initiation (p<0.05) and more smoking in the first hours of the day (p<0.001). Heavy dependent smokers are less likely to quit smoking (p<0.001), lack the confidence to quit by themselves (p<0.001) and less likely to have tried to quit earlier (p<0.001). Dependent smokers are more likely to smoke in the presence of their children (p<0.001). Reasons for smoking included the habit of smoking helping them to keep them going when tired, to make them alert and not knowing what to do with their hands without a cigarette. The main reasons they identified for restarting smoking after quitting were the signs of withdrawal namely headaches, irritability and difficulty in concentration. Nicotine dependence status and attributes were comparable to studies reported in other countries around the world. Enhanced behavioral and medical intervention strategies are needed to motivate helping both low and heavy nicotine dependent smokers to increase the number and effectiveness of quit attempts.

Prevalence of smoking among rural secondary school students in Qualyobia governorate.

A cross sectional study was carried out in two rural secondary schools in Qualyobia governorate in the academic year 2002-2003 in order to assess the students' knowledge, attitudes and practice toward smoking. An anonymous self-administered questionnaire was used. A total of 635 students, 416 males and 219 females were interviewed. The response rate was 100%. The prevalence of ever tried cigarette was 29% (40% among males and 7% among females) with a median age of initiation at 11 years of age. The prevalence of current cigarette smoking among all students was 7.7 (11.5% among males and 0% among females). Waterpipe (Shisha) smoking was reported by 19% (26% among males and 5% among females) with median age of initiation at 12 yearsof age. The risk of smoking is higher among sons of highly educated mothers (OR=3.7, 95% CI=1-12), Boy only school students have almost half the risk of smoking than mixed school male students (OR=0.4, 95% CI=0.2-0.8). On studying the effect of having a smoker family member or friends on students smoking, having a smoker friend increases the risk of male students three time (OR=3, 95%CI=2-5) while others smoking was not statistically significant. More than 90% of the students (both males and females) thought that active and passive smoking are harmful. More females than males thought smoking is addictive (89% of the females and 81% of the males) while more males than females agreed that smokers have more friends (34% of males, 26% of the females) and that smoking makes boys look handsome (8% of males, 3% of females).
