In a cross-sectional questionnaire survey of 1226 students, the lifetime prevalence of ecstasy use was 5.6%. The lifetime prevalence of use of other drugs, mostly cannabis and opium, was 4.6%. A fifth of students (21.8%) were current cigarette smokers and 24.8% had ever used alcohol. After logistic regression, the factors influencing ever use of ecstasy were ever use of other drugs, ever use of alcohol, current cigarette smoking and living alone or with friends. Targeted prevention programmes should be conducted in all colleges.

Tobacco smoking by women is culturally unacceptable in India, but still women smoke tobacco at various times of their life. AIMS: The aim was to estimate the prevalence and pattern of tobacco use among women and to study the associated sociodemographic factors. SETTINGS AND DESIGN: This cross-sectional study was conducted among women aged 30 years or over in an urban resettlement colony for the migrant population at Chandigarh, India. METHODOLOGY: The study included women used tobacco products on one or more days within the past 30 days. Through systematic random sampling, 262 women were studied. As a part of the study 144 bidi smoking women were interviewed using detailed semi-structured questionnaire. STATISTICAL ANALYSIS: Descriptive statistics and hypothesis testing with Chi-squared test and logistic regression were done using SPSS 16.0 version. RESULTS: Overall, the prevalence of tobacco use was 29.4% and that of bidi, zarda and hookah were 19.8%, 8.8%, and 2.7%, respectively. Around 6.2% women used tobacco during pregnancy. Teenage was the most common age of initiation of bidi smoking. Logistic regression analysis showed that the prevalence of tobacco use was high among Hindu unemployed women with no formal education belonged to scheduled caste, and those having grandchildren. CONCLUSIONS: This study highlighted high rates of tobacco use and explored both individual and family factors related to tobacco use among women. Affordable, culturally acceptable, sustainable and gender-sensitive individual and community-specific interventions will reduce the prevalence and effects of tobacco use.

DESIGN: A cross-sectional survey of subjects from randomly selected households. SETTING: Four thousand one hundred forty-two households in Hong Kong. SUBJECTS: A total of 11,779 persons, aged 15 years or older, were enumerated (response rate = 74.0%). MEASURES: A validated structured questionnaire was used for data collection. The questionnaire sought information on the subject's sociodemographic background, smoking habits, and workplace attitude to smoking. The predictors for successful quitting, past quitting attempts, and intention to quit were assessed by chi2 tests and multiple logistic regression. RESULTS: Of the respondents, 14.4% were current smokers, 7.5% were ex-smokers, and 78.1% were nonsmokers. Of the daily smokers, 52% intended to quit. The factors associated with quitting were being married, being in the student/retired/others category, being older, having received higher education, not smoking to kill time, and smoking because of curiosity. Being married and not smoking to kill time were associated with past quitting attempts. Being male, married, and not smoking to kill time were associated with the intention to quit smoking. CONCLUSION: The findings of this study indicate that differing predictors may contribute to the different transitional stages of smoking cessation. Population-based smoking-cessation programs should take these predictors into consideration in the design of interventions.

Most smokers initiate the smoking habit as adolescents or young adults. METHODS: Survey data from the 2007 Lusaka (Zambia) Global Youth Tobacco Survey were used to estimate the prevalence of current cigarette smoking and assess whether exposure to pro-tobacco media and perception of the potential harm of secondhand smoke are associated with adolescents' smoking. Logistic regression analysis was used to estimate the associations. RESULTS: Altogether, 2378 students, of whom 56.8% were females, participated in the study. Overall, 10.5% of the students (9.3% among males and 12.1% among females) smoked cigarettes in the 30 days prior to the survey. Students who favored banning smoking in public places were 33% (OR = 0.67; 95% CI [0.47, 0.96]) less likely to smoke cigarettes compared to those who were not in favor of the ban. Seeing actors smoking in TV shows, videos or movies was positively associated with smoking (OR = 1.90; 95% CI [1.26, 2.88]). However, possessing an item with a cigarette brand logo on it, seeing advertisements of cigarettes on billboards and being ever offered a free cigarette by a cigarette sales representative were negatively associated with smoking (OR=0.39, 95% CI [0.26, 0.58]; OR=0.63, 95% CI [0.43, 0.92]; and OR=0.43, 95% CI [0.29, 0.65], respectively). CONCLUSION: Findings from this study indicate that TV advertisement-promotion-sponsorship was positively associated with smoking, while it was the opposite with other forms of advertisement; there is a need for further studies.

Studies on multiple use among waterpipe smokers are limited. Objectives: We aimed to estimate the proportion of other tobacco products used by current adult waterpipe smokers in Egypt and identify the determinants of multiple tobacco product use. Methods: Population-based surveys were conducted using interview questionnaires during 2015-2017 in urban Cairo and rural Menoufia. Participants aged 18 years and older were selected using purposive quota non-random sampling. The total sample included 2 014 participants. We analysed the data on 1 490 current waterpipe smokers. Variables recorded included: tobacco use, health beliefs, waterpipe smoking behaviour, sociodemographic characteristics, and perceived effectiveness of pictorial health warnings on waterpipe tobacco packs. Current waterpipe smokers were classified as waterpipe-only users and multiple tobacco product users. Results: Almost half (47.9%) of the current waterpipe smokers used multiple tobacco products; 93.4% were dual users and 6.6% poly-users. The other tobacco products used were cigarettes (86.4%), electronic nicotine delivery systems (ENDS) (7.0%) or both (6.6%). Multiple users were more likely to be younger than waterpipe-only users. Young adult female waterpipe smokers used ENDS 12 times more than young adult males (48.8% versus 4.1% respectively). Non-daily waterpipe smoking, usually smoking at cafes, higher education and knowledge of pictorial health warnings were independent predictors of multiple tobacco product use. Conclusion: Multiple tobacco product use was common among current waterpipe smokers in our study. Interventions to tackle non-cigarette and multiple tobacco use, especially in young adults, are urgently needed. Descriptors Links Book Title Database Publisher . Some rights reserved.

It has been suggested that PHWs would be more salient if placed on the waterpipe device itself. This qualitative study explored how participants perceived the effects placing PHWs on waterpipe devices would have on warning salience and uptake or quitting of WTS. METHODS: We conducted 10 focus groups and 10 in-depth interviews with 90 adult waterpipe smokers and non-smokers, men and women, who lived in rural, semi-urban and urban regions of Egypt. We presented participants with four novel PHWs of different sizes positioned randomly at four locations on a waterpipe device (the glass body, metal holder, mouthpiece or hose), one at a time. At each session, participants viewed a PHW on all four locations. Novel warnings were shown on plain labels with a dark uniform background and featured pictures, text and the quitline number. Transcripts were analysed using thematic analysis. RESULTS: Participants thought placing PHWs on waterpipe devices might increase salience, prevent WTS initiation or trigger quit attempts; they favoured placing PHWs on the glass body, mouthpiece or waterpipe hose. Both waterpipe smoker and non-smoker participants thought these potential effects would affect non-smokers or non-established smokers more than established waterpipe users. CONCLUSIONS: Our exploratory study suggests that PHWs featured prominently on waterpipe devices could potentially deter experimentation with waterpipe tobacco products and promote cessation, especially among non-established users.

Bonding to cervical enamel can generate significantly lower bond strengths than bonding to other enamel areas. The effect of enamel pretreatment on bond strengths of self-etch and self-adhesive resin cements to cervical enamel remains undetermined. PURPOSE: The purpose of this study was to evaluate cervical enamel bond strengths of self-adhesive, self-etch resin cements according to acid pretreatment, using a total-etch resin cement as the control. MATERIAL AND METHODS: The proximal surfaces of 20 extracted molars were sectioned to obtain 40 enamel rectangles with an area of 8.0 x 4.0 mm. The rectangular enamel specimens were assigned to 1 of 5 enamel experimental groups: intact enamel + RelyX Unicem (UN), etched enamel + UN (UNpa), intact enamel + Multilink (ML), etched enamel + ML (MLpa), and the total-etch-based RelyX ARC (RX; control group). Standard 8.0 x 4.0 x 6.0-mm composite resin blocks (Z250) were cemented to all specimens. The bonded enamel surfaces were sectioned into sticks with a cross-section of 0.8 +/-0.2 mm(2) and tested to failure in tension mode at a crosshead speed of 1 mm/min. The data were submitted to 1-way analysis of variance (ANOVA), followed by Tukey's HSD post hoc test (alpha=.05). Additionally, the enamel etching pattern was investigated for all experimental groups using field-emission electron microscopy. RESULTS: Statistical analysis showed significant differences among different resin cements (P RX (19.40 (9.47)). Acid etching of enamel before application of self-etch resin cement did not improve the mean bond strengths (SD) for self-etch resin cement [ML (5.38 (5.97)); MLpa (5.23 (1.1))]. Self-adhesive and self-etch resin cements yielded the lowest significant mean bond strengths (SD) when applied on intact enamel: UN (13.03 (2.82)) > ML (5.38 (5.97)). Scanning electron microscopy showed a consistent etching pattern for phosphoric acid-etched specimens. Self-etch and self-adhesive resin cements applied directly to intact enamel showed inconsistent areas of etching. CONCLUSIONS: Etching cervical enamel surfaces resulted in significantly higher bond strengths for self-adhesive resin cement. For self-etch resin cement, etching did not improve bond strength.

METHOD AND MATERIALS: One hundred twenty extracted teeth were wet ground to create a flat bonding area on enamel and dentin. Three bonding agents (Adper Prompt-L-Pop, Clearfil SE Bond, and Xeno III) were applied to either dentin or enamel according to the manufacturers' directions. In half of the specimens, bonding agents were light cured immediately after their application (Group PRC). The other half were not light cured until resin composite application (Group COC). Resin composite was placed into a Teflon tube and light cured over the adhesive. Specimens were stored in deionized water for 24 hours at room temperature before being loaded in shear until failure with an Instron testing machine. Shear bond strength (in megapascals) was analyzed with 2-factor ANOVA, separate single-factor ANOVA models for cure and material, and Tukey's Honestly Significant Differences multiple comparison procedure. All testing was performed at the 5% significance level (n=10). RESULTS: Light-curing the adhesive separately produced significantly higher bond strengths to dentin (P <.001) than did the co-cure method. Group PRC did not produce significantly different bond strengths to enamel (P = .420). CONCLUSIONS: Pre-curing of self-etching adhesives before curing of the resin composite produces greater bond strength to dentin. The curing technique has no significant effect on enamel bond strength of self-etching adhesives.
