Tobacco smoking is an emerging problem among adolescents in the United Arab Emirates (UAE). This study aimed to measure the prevalence of current tobacco use and its associated factors among school students in Dubai Emirate and to determine the impact of an intervention programme on knowledge and attitudes towards tobacco use. A school-based intervention programme was carried out among 2457 students aged 10-20 years and data were collected with a self-administered questionnaire. Of the students, 14.6% were tobacco users, mostly cigarettes (11.2%) and waterpipes (2.2%). The most common self-reported reasons for smoking were for the experience (29.4%), for stress relief (22.5%) and because their peers smoked (21.9%). Stepwise logistic regression analysis showed that the predictors of tobacco use were: male, higher age, UAE national, higher school level, government school, low knowledge about tobacco and family history of smoking. There were significant improvements in knowledge and attitudes scores after the health education intervention programme. 1Primary Health Care, Dubai Health Authority, Dubai, United Arab Emirates (Correspondence to H.A. Obaid: haobaid@dha.gov.ae). Parmi les élèves interrogés, 14,6 % étaient des consommateurs de tabac, principalement de cigarettes (11,2 %) ou de pipes à eau (2,2 %). Les raisons les plus fréquentes motivant la consommation de tabac étaient le fait d'expérimenter (29,4 %), l'atténuation du stress (22,5 %) et la consommation de tabac par les pairs (21,9 %). L'analyse de régression logistique par étapes a démontré que les facteurs prédictifs du tabagisme étaient les suivants : être de sexe masculin, être plus âgé, avoir la nationalité émirienne, avoir un niveau scolaire plus élevé, fréquenter une école publique, avoir de faibles connaissances sur le tabac et venir d'une famille de fumeurs. Des améliorations notables ont été constatées dans les scores sur les connaissances et les attitudes après la mise en oeuvre du programme d'interventions d'éducation pour la santé.
The trend of incidence of ovarian cancer was studied, the 5-year survival rate calculated and prognostic factors for survival determined. Data were collected from the Alexandria Cancer Registry and medical records in various hospitals. A total of 358 cases of ovarian cancer were diagnosed from 1988 to 1997. A significant increasing trend in incidence of ovarian cancer from 1.23/100 000 in 1988 to 3.16/100 000 in 1997 was found. The overall 5-year survival rate was 46%. The 5-year survival rates for tumour stages I to IV were 85%, 71%, 41% and 22% respectively, which was statistically significant. Survival rates with poorly differentiated tumours were significantly worse than with moderate or well differentiated tumours
