Beliefs and attitudes related to narghile (waterpipe) smoking among university students in Syria

PURPOSE: To assess the beliefs and attitudes related to narghile (waterpipe) smoking that are likely to contribute to its increased popularity among young people in Syria. METHODS: In 2003, a cross-sectional survey was administered to university students in Aleppo, using an interviewer-administered questionnaire. Overall, 587 students participated in the study (278 males, 309 females; mean age, 21.8 +/- 2.1; response rate 98.8%). RESULTS: The most common positive perceptions of narghile were related to its smell and taste. Negative perceptions of narghile included the smoke produced, the pollution, and perceived adverse health effects. Students believed the popularity of narghile to be part of a rising regional trend in its use, due to its being an appealing way to spend leisure time socializing with friends. More students (49.7%) believed narghile to be more harmful to health than cigarettes, compared with 30% who believed the opposite. Respiratory disease was the most commonly cited health effect of narghile smoking. Family attitudes regarding tobacco use by younger members were more permissive about narghile compared with cigarettes, and, surprisingly, were more permissive about females smoking narghile than males doing so. CONCLUSIONS: The rise in narghile smoking as a trendy social habit appears to be occurring despite considerable appreciation of its potential health risks. Permissiveness of adult family members towards narghile use by young female members, especially in the presence of a strong taboo against female cigarette smoking may contribute to the continuous spread of narghile smoking among women in Syria.     

Can an information booklet on an ethnic minority increase the knowledge base of junior doctors?

Many doctors encounter people of different cultural backgrounds for the first time as patients. In Leicester a significant proportion of the area's population comes from a Gujarati and Hindu background. In an attempt to better inform junior doctors about the views and beliefs of their patients, a group of clinicians and administrators developed an information booklet about the beliefs and practices of people from this community. The impact of this booklet on a group of 54 junior doctors' knowledge was investigated over a period of one month. Such an information booklet was found to significantly increase awareness of the cultural background of patients from a minority community and this knowledge was maintained for at least one month after distribution. The study did not investigate impact on attitudes.     

Estimating the beginning of the waterpipe epidemic in Syria

Background

Waterpipe smoking is becoming a global public health problem, especially in the Eastern Mediterranean region (EMR).

Methods

We try in this study, which is a cross sectional survey among a representative sample of waterpipe smokers in cafes/restaurants in Aleppo-Syria, to assess the time period for the beginning of this new smoking hype. We recruited 268 waterpipe smokers (161 men, 107 women; mean age ± standard deviation (SD) 30.1 ± 10.2, response rate 95.3%). Participants were divided into 4 birth cohorts (≤ 1960, 1961–1970, 1971–1980, >1980) and year of initiation of waterpipe smoking and daily cigarette smoking were plotted according to these birth cohorts.

Results

Data indicate that unlike initiation of cigarette smoking, which shows a clear age-related pattern, the nineties was the starting point for most of waterpipe smoking implicating this time period for the beginning of the waterpipe epidemic in Syria.

Conclusion

The introduction of new flavored and aromatic waterpipe tobacco (Maassel), and the proliferation of satellite and electronic media during the nineties may have helped spread the new hype all over the Arab World.

     

Measuring the prevalence of overweight in Texas schoolchildren

OBJECTIVES: We describe results from year 1 of a surveillance system to monitor body mass index in children at the state level. METHODS: A sample of 6630 children attending Texas public schools, weighted to represent 4th, 8th, and 11th grades within race/ethnic subpopulations, was assessed. Body mass index was calculated from measured height and weight; demographic information was obtained from a questionnaire. RESULTS: Prevalence of overweight was 22.4%, 19.2%, and 15.5% for 4th-, 8th-, and 11th-grade students, respectively. Overweight prevalence was highest among Hispanic boys (29.5%-32.6%), fourth-grade Hispanic girls (26.7%), and fourth- and eighth-grade African American girls (30.8% and 23.1%, respectively). Eleventh-grade White/other girls had the lowest prevalence of overweight (5.5%). CONCLUSIONS: These data confirm the increasing prevalence of overweight among US children, especially among Hispanic and African American students compared to White/other students and fourth-grade students relative to 8th- and 11th-grade students.     

Phenolic acid metabolites as biomarkers for tea- and coffee-derived polyphenol exposure in human subjects

Tea and coffee are rich in polyphenols with a variety of biological activities. Many of the demonstrated activities are consistent with favourable effects on the risk of chronic diseases. 4-O-methylgallic acid (4OMGA) and isoferulic acid are potential biomarkers of exposure to polyphenols derived from tea and coffee respectively. 4OMGA is derived from gallic acid in tea, and isoferulic acid is derived from chlorogenic acid in coffee. Our major objective was to explore the relationships of tea and coffee intake with 24 h urinary excretion of 4OMGA and isoferulic acid in human subjects. The relationships of long-term usual (111 participants) and contemporaneously recorded current (344 participants) tea and coffee intake with 24 h urinary excretion of 4OMGA and isoferulic acid were assessed in two populations. 4OMGA was related to usual (r 0.50, P<0.001) and current (r 0.57, P<0.001) tea intake, and isoferulic acid was related to usual (r 0.26, P=0.008) and current (r 0.18, P<0.001) coffee intake. Overall, our present results are consistent with the proposal that 4OMGA is a good biomarker for black tea-derived polyphenol exposure, but isoferulic acid may be of limited usefulness as a biomarker for coffee-derived polyphenol exposure.     

Effect of 5-MCA-NAT, a putative melatonin MT3 receptor agonist, on intraocular pressure in glaucomatous monkey eyes

PURPOSE: 5-MCA-NAT, a putative melatonin MT3 receptor agonist, reduced intraocular pressure (IOP) in ocular normotensive rabbit eyes. This study evaluates the effect of topical application of 5-MCA-NAT on IOP in monkey eyes with laser-induced unilateral glaucoma. METHODS: A multiple-dose study was performed in 8 glaucomatous monkey eyes. One 25-microL drop of 5-MCA-NAT (2%) was applied topically to the glaucomatous eye at 9:30 am and 3:30 pm for 5 consecutive days. IOP was measured hourly for 6 hours beginning at 9:30 am for one baseline day, one vehicle-treated day, and treatment days 1, 3, and 5 with 5-MCA-NAT. RESULTS: Compared with vehicle treatment, twice daily administration of 5-MCA-NAT for 5 days reduced (P < 0.05) IOP from 1 hour to 5 hours after the first dose, and the IOP-lowering effects were shown to last at least 18 hours following administration, based on IOP measurements made after the fourth and eighth doses. The ocular hypotensive effect of 5-MCA-NAT was enhanced with repeated dosing. The maximum reduction (P < 0.001) of IOP occurred at 3 hours after each morning dose, and was 4.0 +/- 0.5 (mean +/- SEM) mm Hg (10%) on day 1, 5.6 +/- 0.8 mm Hg (15%) on day 3, and 7.0 +/- 1.1 mm Hg (19%) on day 5. Adverse ocular or systemic side effects were not observed during the 5 days of treatment. CONCLUSIONS: 5-MCA-NAT, a putative melatonin MT3 receptor agonist, reduces IOP in glaucomatous monkey eyes. Melatonin agonists with activity on the putative MT3 receptor may have clinical potential for treating elevated IOP.
