Prevalence and co-occurrence of unhealthy lifestyle habits and behaviours among secondary school students in Tuscany, central Italy.

OBJECTIVES: Unhealthy habits acquired during adolescence may persist in adulthood and eventually increase the risk of chronic illnesses. STUDY DESIGN: We reported on a survey conducted in 2013-2015 among secondary school students in Tuscany, central Italy. METHODS: We compared the prevalence of self-reported lifestyle characteristics and overweight/obesity between genders and age groups (14-16 vs 17-21 years). We partitioned each gender- and age-specific stratum into groups based on cigarette smoking and engagement in sport activities, and compared the prevalence of other unhealthy lifestyles across groups using Poisson regression. RESULTS: Overall, 2167 students (53.3% males, mean age 16.8 years) were included. Males were more frequently overweight/obese than females. Cigarette smoking increased with age and did not differ by gender. Males were more likely to engage in sport activities, drink alcoholic beverages and adopt other unhealthy lifestyle habits, whereas females reported a more frequent use of painkillers. Cigarette smoking was the single lifestyle characteristic most consistently associated with other unhealthy habits. CONCLUSIONS: The prevalence and patterns of co-occurrence of unhealthy lifestyle habits varied by gender and age group among secondary school students in Italy. Our findings should be taken into account when planning public health initiatives aiming to combat obesity and tackle unhealthy lifestyles among secondary school students in Italy.

Genetic determinants of alcohol addiction and metabolism: a survey in Italy.

BACKGROUND: Although multiple genes are involved in alcoholism and can contribute differently to the risk of dependence and liver damage, no studies have investigated susceptibility to addiction in combination with susceptibility to liver damage due to differences in ethanol metabolism. METHODS: We evaluated the role of three polymorphic genes related to alcohol metabolism (CYP2E1) and, possibly, dependence (DRD2 and SLC6A4 promoter) in a series of 60 alcoholics admitted to a specialized referral center in Florence, Italy. Eighteen had a diagnosis of liver cirrhosis. A control series of 64 blood donors were identified at the same hospital. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism methods. RESULTS: No difference was found in the frequency of the CYP2E1 Rsal c2 allele (2.5% among alcoholics and 4.7% among controls) and the DraI C allele (6.7% and 10.1%). Similarly, no difference was found in the frequency of the DRD2 A1 allele (15.8% and 13.3%) and the B1 allele (10.8% and 8.6%). The proportion of controls with a combined B1 genotype (B1/B1 or B1/B2) was significantly associated with smoking (p = 0.03). The distribution of the S and L allele of the SLC6A4 gene was similar in the two groups, with 15% and 14%, respectively, homozygous S/S carriers. A significant association, however, emerged in the group of alcoholics, with a five times higher risk for S/S carriers of developing cirrhosis (p < 0.05). This association with liver persisted even after exclusion of the subgrouped of 10 hepatitis C virus positive alcoholics. CONCLUSIONS: Overall, our results provided no evidence of an increased susceptibility to develop alcoholism that was associated with the three genotypes investigated, either alone or in combination. An increased risk of developing liver cirrhosis for S/S homozygous carriers among alcohol-dependent patients was observed for the first time.

Introduction: community action research and the prevention of alcohol problems at the local level.

Many community action projects from around the world exist to reduce alcohol problems at the local level. The role of research within this international movement is discussed within this introduction for the entire special issue on community action research in alcohol problem prevention. Previous community prevention programs have utilized a variety of prevention strategies: (a) an educational approach which focuses on changing behavior through changes in knowledge, attitudes, and information; and (b) an environmental approach which focuses on changing behavior through changes in the social and economic systems within a community. Many projects have used both approaches. This special issue provides a current overview of many types of community action projects from different countries and summarizes what has been learned to date from these experiences.

Alcohol carousel and children's school drawings as part of a community educational strategy.

Within a community action research program, messages for the community population can be conveyed through already existing channels (newspapers, magazines, TV, radio) or special tools can be created. As part of the Rifredi Health District (16,900 inhabitants), Florence, Italy, Community Alcohol Action Research Project, 5,500 alcohol carousels (translated and adapted from the Stockholm carousel) were distributed during 1996 in the project's area where they were freely available. Two samples, one of a consumers' association (response rate 26%) and the other of school parents, employed a questionnaire. A few local key people underwent a qualitative interview. In all circumstances the carousel proved to be understandable, useful, and able to elicit discussions about alcohol issues. In 1996-97, after a 2-year training program in communication skills and alcohol prevention, 13 teachers in local preschools, elementary schools, and middle schools planned and implemented a health education program on the issues of alcohol and food. One outcome was nine drawings produced by the school children. The drawings were exhibited in some schools and supermarkets, and were hung in city buses.
