- Estado actual e evolução da epidemia tabágica: em Portugal e na EuropaPublication . Precioso, J; Calheiros, JM; Pereira, D; Campos, H; Antunes, H; Rebelo, L; Bonito, JTobacco smoking is the cause of more than half million deaths/year in the European Union (EU). Monitoring smoking prevalence is an important tool to evaluate the epidemic and its evolution and to assess the effectiveness of preventive measures. The comparison between countries may help us identify good control practices. OBJECTIVE: To describe the current state and evolution of the smoking epidemic in several EU countries, and to characterize the Portuguese situation in comparison with those countries. METHODS: To characterize smoking habits and their evolution in the population over 15 years old, several Eurobarometer reports from 1995 to 2007 were used. The characterization of School Aged Children's smoking habits was based on the Health Behaviour in School-Aged Children data of 1993-4 and 2002. The Portuguese situation also used the information available from the National Health Surveys of 1987 up to 2005/06. RESULTS: The global prevalence of smoking in adult population in most of the European countries is over 25%. The average prevalence of male and female smokers in School-Aged Children over 15 years of age is approximately 18% if we consider both genders together. In most countries the prevalence of tobacco consumption is higher in girls when compared to boys. In Portugal, the prevalence in the population over 15 years of age has one of the lowest values among European countries (30,6 % for men and 11,6% for women). Despite these crude prevalence rates, high age-sex-specific prevalence rates were found in age groups 25-34 and 35-44 in men (39,9% e 44,6% respectively) and in women (17,6 e 21,2% respectively). In 2002, at the age of 15, the percentage of daily smoking girls in Portugal was 19.5%. This value reveals that Portugal is among the countries with higher prevalence rates of smoking among adolescent girls. Over the last decade (1996-2006), a decrease in tobacco consumption has been observed in most EU countries, both in adult population and in School-Aged Children. In Portugal, this consumption has levelled off in adult men and in youngsters aged 15, but shows a significant increase in female adults and school-aged girls. CONCLUSIONS: Although Portugal presents low global prevalence rates in the European context, the substantial increases observed in the young adult female population are of particular concern because of its impact on women's health and the risk of pre and post-natal associated childhood exposure. These results reveal that current preventive strategies in Portugal are ineffective in reducing smoking prevalence among children and young adults.
- Exposição das crianças ao fumo ambiental do tabaco (FAT): avaliação de uma intervenção preventivaPublication . Precioso, J; Samorinha, C; Calheiros, JM; Macedo, M; Antunes, H; Campos, HTo evaluate the effectiveness of the preventative programme "Smoke-free Homes" undertaken in 4th year children and their parents or guardians, aiming to reduce children's exposure to second hand smoke (SHS) in the home. MATERIAL AND METHODS: This was a pre- and post-test pre-experimental study, in students from 32 Braga district primary schools 2007/08. A self-administered and structured questionnaire was given out to 795 students in the classroom before and after the programme. In analysing data, we used the chi-squared test for the categorical variables. RESULTS: The rate of children exposed to regular or occasional SHS due to living with at least one smoker dropped from 42.2% to 32.6% (p=0.001). The percentage of students, children of smokers who stated that their father smoked regularly or occasionally at home, dropped from 68.0% pre-test to 51.6% posttest (p=0.000). No significant reduction was seen in mothers. CONCLUSION: Based on the data, we can conclude that the "Smoke-free Homes" programme was effective in preventing smoking in the home, and therefore reducing the rate of children exposed to SHS by about 10%. However, it appears that about a third of children are still exposed, which highlights the need for further measures in this area. Healthcare professionals, particularly those working in Paediatrics, should advise parents to quit smoking, especially in the home.
