Stimulant substance use and gambling behaviour in adolescents. Gambling and stimulant use. / Uso de sustancias estimulantes y comportamiento de juego en adolescentes. Juego y uso de estimulantes.

Gambling is widely recognized as an important public health problem. Despite the rising use of stimulant substances among adolescents, there are still very few studies focusing on whether adolescents' use of stimulants is associated with their gambling behaviour. Therefore, the aim of this study was to investigate the association between gambling habits and consumption of stimulants such as coffee, energy drinks, and new psychoactive substances in a sample of Italian adolescents. A survey was conducted in 2017 with a representative sample of Italians between the ages of 14-17 years, comprising 15,833 students attending 201 secondary schools. Logistic regression analyses were run to assess the association between at-risk/problem gambling (O1) and independent predictors: the model included independent variables (coffee, energy drinks and new psychoactive substance consumption) and covariates (demographic variables, social environment variables and risk-taking behaviour variables). A sensitivity analysis was also conducted to examine a second dependent variable regarding any experience of gambling behaviour (O2). Adolescents who were at-risk gamblers or problem gamblers were significantly more likely to consume energy drinks than non-gamblers or not-at-risk gamblers. A similar pattern was seen for consumption of new psychoactive substances. No significant association emerged with coffee consumption. The sensitivity analysis showed that, compared with non gamblers, the group of gamblers had higher odds for frequent coffee consumption, as well as for consumption of energy drinks and/or new psychoactive substances. Screening for gambling and stimulant use may provide important information, as it may be necessary to take action to reduce stimulant substance use as part of efforts to deal with unhealthy gambling habits.

El juego es un importante problema de salud pública ampliamente reconocido. A pesar del creciente uso de sustancias estimulantes entre los adolescentes, todavía son escasos los estudios centrados en verificar la existencia de una asociación entre el uso de estimulantes y los comportamientos relacionados con el juego en adolescentes. Por tanto, este estudio tuvo como objetivo investigar la asociación entre los hábitos relacionados con el juego y el consumo de sustancias estimulantes como el café, las bebidas energizantes y las nuevas sustancias psicoactivas en una muestra de adolescentes italianos. En 2017 se realizó una encuesta en una muestra representativa de jóvenes italianos de 14 a 17 años, constituida por 15 833 estudiantes provenientes de 201 escuelas de educación secundaria. Se realizó un análisis de regresión logística para evaluar la asociación entre juego de riesgo/juego problemático (R1) y factores predictivos independientes: el modelo incluyó variables independientes (café, bebida energética y consumo de nuevas sustancias psicoactivas) y otras covariables demográficas, del entorno social y de conductas de riesgo. También se realizó un análisis de sensibilidad para examinar una segunda variable dependiente con respecto a cualquier experiencia de conductas relacionadas con el juego (R2). Los adolescentes clasificados como jugadores de riesgo o jugadores con problemas tenían una probabilidad significativamente mayor de consumir bebidas energizantes que los no jugadores o los jugadores sin riesgo. Se observó un patrón similar en el consumo de nuevas sustancias psicoactivas. No se evidenció ninguna asociación significativa con el consumo de café. El análisis de sensibilidad mostró que, en comparación con los no jugadores, el grupo de jugadores tenía mayores probabilidades de consumo frecuente de café, bebidas energéticas y/o nuevas sustancias psicoactivas. La evaluación del juego y el uso de sustancias estimulantes puede proporcionar información importante. Por consiguiente, podría ser necesario tomar medidas para reducir el uso de sustancias estimulantes como parte de los esfuerzos dirigidos a lidiar con los hábitos de juego poco saludables.

Increasing prevalence of HIV infection among first time clients in Italian drug treatment services - is it sexual transmission?

BACKGROUND: Over the last two decades, the proportion of people who inject drugs among newly reported HIV cases in Italy has been continuously declining. This trend is reflected in the prevalence of HIV infection among problem drug users followed in drug treatment services. We report nationwide trends in the prevalence of HIV and HCV among tested clients in charge to drug addiction services from 2005 to 2011. METHODS: Data on the prevalence of HIV and HCV among drug users from public drug treatment services across Italy were collected and analyzed for the period from 2005 to 2011. Prevalence of HIV and HCV were compared between clients returning to treatment and those entering treatment for the first time, and by gender. Due to the high percentage of missing data, the "inverse probability weight" method was used. Trends in testing uptake were also analysed. RESULTS: A significant decrease of HIV and HCV prevalence is observed among all PDUs entering treatment (from 14.7% to 11.1% and from 61.6% to 50%, respectively, in 2005-2011). By contrast, among those entering the services for the first time, after an initial decline the prevalence of HIV infection steadily increased in both sexes, from 2.2% in 2009 to 5.3% in 2011. Self-reported injecting rates in this group decreased over time, and in 2011 the proportion reporting drug injecting was lower among new clients than in people returning to services (14.5 vs. 34.4%). We also observed a progressive and significant reduction in HIV and HCV testing in drug treatment services. CONCLUSIONS: Changes in injection practice and type of drugs used, coupled with a concurrent reduction in HCV prevalence, do not support drug injection as the main explanation for an increased HIV transmission in people entering drug treatment services for the first time. While reductions in testing rates raise concerns over data quality, the possibility of increased sexual transmission needs to be considered.

Mapping SAGE questionnaire to the International Classification of Functioning, Disability and Health (ICF).

The collaborative research on ageing in Europe protocol was based on that of the World Health Organization Study on global AGEing and adult health (SAGE) project that investigated the relationship between health and well-being and provided a set of instruments that can be used across countries to monitor health and health-related outcomes of older populations as well as the strategies for addressing issues concerning the ageing process. To evaluate the degree to which SAGE protocol covered the spectrum of disability given the scope of the World Health Organization International Classification of Functioning, Disability and Health (ICF), a mapping exercise was performed with SAGE protocol. Results show that the SAGE protocol covers ICF domains in a non-uniform way, with environmental factors categories being underrepresented, whereas mental, cardiovascular, sensory functions and mobility were overrepresented. To overcome this partial coverage of ICF functioning categories, new assessment instruments have been developed. PRACTITIONER MESSAGE: Mapping exercises are valid procedures to understand the extent to which a survey protocol covers the spectrum of functioning. The mapping exercise with SAGE protocol shows that it provides only a partial representation of body functions and activities and participation domains, and the coverage of environmental factors is poor. New instruments are therefore needed for researchers to properly understand the health and disability of ageing populations.

Validation of the COURAGE Built Environment Self-Reported Questionnaire.

UNLABELLED: The built environment (BE) impacts on people's disability and health, in terms of overweight, depression, alcohol abuse, poor self-rated health and presence of psychological symptoms; it is reasonable to assume that BE also impacts on participation levels. This paper presents the validation of the COURAGE Built Environment Self-Reported Questionnaire (CBE-SR), an instrument designed to evaluate BE in the context of health and disability. Subjects participating to COURAGE, a cross-sectional study conducted on 10,800 citizens of Poland, Finland and Spain, completed a protocol inclusive of the CBE-SR. Psychometric properties and factor structure were analysed, and factor scores created. Gender differences, differences between persons from different age groups and persons reporting the environment as facilitating, hindering or neutral were calculated. Eight items were deleted so that the final version of CBE-SR comprises 19 items. Cronbach's alpha ranged from 0.743 to 0.906, and test-retest stability was demonstrated for the majority of items. Four subscales were identified: Usability of the neighbourhood environment; Hindrance of walkable environment; Easiness of use of public buildings, places and facilities; and Risk of accidents and usability of the living place. Younger respondents reported their neighbourhood as more usable but perceived walkways as more hindering and public buildings as less easy to use; gender differences were almost inexistent. The CBE-SR is a four-scale instrument with good psychometric properties that measures the person-environment interaction. It is sensitive across age groups and is consistent with the subject's overall judgement of the degree to which the environment is facilitating or hindering. KEY PRACTITIONER MESSAGE: Poor built environments have a negative impact on the level of a person's participation. However, instruments measuring the person-environment interaction are lacking. The CBE-SR is a valid and reliable instrument that researchers can use to assess the relationships between the intrinsic health state and the objective features of the environment. Understanding this relationship would provide further insight into the need of addressing the individual's functioning either by means of interventions directed to the individual or by making changes to the individual's environment.

The COURAGE Built Environment Outdoor Checklist: an objective built environment instrument to investigate the impact of the environment on health and disability.

UNLABELLED: A tool to assess the built environment, which takes into account issues of disability, accessibility and the need for data comparable across countries and populations, is much needed. The Collaborative Research on Ageing in Europe (COURAGE) in Europe Built Environment Outdoor Checklist (CBE-OUT) helps us to understand when features of the neighbourhood environment have either a positive or negative impact on the accessibility of neighbourhoods for healthy ageing. The CBE-OUT is composed of 128 items that can be recorded when present in the evaluated environment. Audits were performed in households randomly selected from each cluster of the sample for Finland, Poland and Spain, following precise rules defined by experts. Global scores were computed both section by section and in the overall checklist, rescaling the resulting scores from 0 (negative environment) to 100 (positive). The total number of completed CBE-OUT checklists was 2452 (Finland, 245; Poland, 972; and Spain, 1235). Mean global score for our sample is 49.3, suggesting an environment composed both of facilitating and hindering features. Significant differences were observed in the built environment features of the three countries and in particular between Finland and the other two. The assessment of features of built environment is crucial when thinking about ageing and enhanced participation. The COURAGE in Europe project developed this tool to collect information on built environment in an objective evaluation of environmental features and is a recommended methodology for future studies. KEY PRACTITIONER MESSAGE: The CBE-OUT checklist is an objective evaluation of the built environment and is centred on technical measurement of features present in the environment and has its foundations in the concepts of disability and accessibility operating in the International Classification of Functioning, Disability and Health (ICF) model. The CBE-OUT checklist can be analysed using both the total score and the single section score, allowing an evaluation of the facilitating or hindering role of the environment and is usable for predictive analysis of ageing trends. The CBE-OUT checklist makes it possible to collect information about the built environment by means of an objective evaluation of environment features and is a recommended methodology for future studies about the built environment.

Psychosocial risk and protective factors for youth problem behavior are associated with food addiction in the Generation Z.

Objective: Food Addiction (FA) and other well-known risk behavior as substance misuse tend to co-occur and may share similar risk and protective factors. The aim of this study was to assess the association between the diagnosis/severity of FA and psychosocial domains typically related to risk behavior syndrome in a large, nationally representative community sample of Generation Z underage Italian students. Method: The sample consisted of 8,755 students (3,623 from middle schools, 5,132 from high schools). A short version of the Yale Food Addiction Scale 2.0 was administered to evaluate FA. Risk and protective factors related to demographic, personality, behavior, and family variables were examined. Stepwise multivariate logistic and linear regressions were conducted. Results: The prevalence of FA was 30.8%. Female gender, social anxiety and depression symptoms, social withdrawal risk, Internet gaming disorder, social media addiction, current substance use, social challenge engagement and experienced doxing boosted the chance of FA diagnosis, whereas eating fruit and vegetables, playing competitive sports and an average sleep duration of 7-8 h per night reduced these odds. FA severity was significantly and positively associated with trait impulsiveness, social anxiety and depressive symptoms, risk of social withdrawal, recent substance use, social media, and gaming addiction, doxing suffered and risky social challenges participation. Negative associations between the severity of FA and fruit and vegetable diet habits were found. Conclusion: Our findings confirm that FA is widespread among Italian adolescents. The associations between the diagnosis and severity of FA and psychosocial risk factors for health, including, addictive and deviant behaviors related to digital misuse, suggest its belonging to the risk behavior constellation. Health promotion schemes based on a multicomponent strategy of intervention should consider the inclusion of FA and its psychosocial correlates.

Cancer incidence in immigrants by geographical area of origin: data from the Veneto Tumour Registry, Northeastern Italy.

Objective: We investigated whether there are differences in cancer incidence by geographical area of origin in North-eastern Italy. Methods: We selected all incident cases recorded in the Veneto Tumour Registry in the period 2015-2019. Subjects were classified, based on the country of birth, in six geographical areas of origin (Italy, Highly Developed Countries-HDC, Eastern Europe, Asia, Africa, South-central America). Age-standardized incidence rates and incidence rate ratio (IRR) were calculated, for all cancer sites and for colorectal, liver, breast and cervical cancer separately. Results: We recorded 159,486 all-site cancer cases; 5.2% cases occurred in subjects born outside Italy, the majority from High Migratory Pressure Countries (HMPC) (74.3%). Incidence rates were significantly lower in subjects born in HMPC in both sexes. Immigrants, in particular born in Asia and Africa, showed lower rates of all site cancer incidence. The lowest IRR for colorectal cancer was observed in males from South-Central America (IRR 0.19, 95%CI 0.09-0.44) and in females from Asia (IRR 0.32, 95%CI 0.18-0.70). The IRR of breast cancer appeared significantly lower than Italian natives in all female populations, except for those coming from HDC. Females from Eastern Europe showed a higher IRR for cervical cancer (IRR 2.02, 95%CI 1.57-2.61). Conclusion: Cancer incidence was found lower in subjects born outside Italy, with differences in incidence patterns depending on geographical area of origin and the cancer type in question. Further studies, focused on the country of birth of the immigrant population, would help to identify specific risk factors influencing cancer incidence.

Current practice in colonoscopy in the elderly.

Colonoscopy in the elderly is a reliable practice of great diagnostic and management value. However, patient's age has long been considered to affect the success of the procedure, achieved when the cecum is intubated, there is a good view of the colon if preparation has been properly carried out, and the examination does not cause excessive discomfort or complications. Substantial improvements have been made to the latter two aspects, due to more widespread use of deep sedation with propofol and cardiocirculatory monitoring during the procedure. The aim of our work was to assess whether, in the everyday practice of an open-access, digestive endoscopy teaching center, staffed by various providers delivering screening for polyposis, age is still a limitation to the success of the procedure and whether appropriate measures have been taken to improve colonoscopy in geriatric patients. We analysed 1480 consecutive colonoscopies, of which 319 were performed in patients aged over 73 years. The examination was significantly less successful in this group of patients (88.1 vs 94.4, p=0.0001), but there were no major technical or use-related complications connected with administration of propofol for sedation purposes, despite lower doses to the elderly (2.2 ± 1.1 mg/kg total dose, mean 151 ± 72.4 mg vs 2.9 ± 1.3 mg/kg total dose, mean 199 ± 77.9 mg in younger patients, p<0.001). More experienced technical staff were not allocated to these colonoscopies (for endoscopic or anesthesiological purposes) and, according to the results of multivariate stepwise logistic regression analysis, inadequate preparation was the main factor affecting the success of the procedure in elderly patients (OR 5.9, 95% CI 2.25-15.72; p=0.0003). Only body weight over 60 kg facilitated it (weight ≥ 60 kg, OR 0.46, 95% CI 0.26-0.83). In colonoscopy in the elderly, safety appears to be the primary concern and, good outcomes can be achieved, but sometimes at the expense of diagnostic accuracy. This could probably be improved through better pre- and post-procedure care, not currently differentiated between young and elderly patients.

Usefulness of a fast track list for anxious patients in a upper GI endoscopy.

BACKGROUND: To determine whether patients with no alarm signs who ask the endoscopist to shorten their waiting time due to test result anxiety, represent a risk category for a major organic pathology. METHODS: At our open-access endoscopy service, we set up an expedite list for six months for outpatients who complained that the waiting time for gastroscopy was too long. Over this period we studied 373 gastroscopy patients. In addition to personal details, we collected information on the presence of Hp infection and compliance with dyspepsia guideline indications for gastroscopy. RESULTS: Average waiting time was 38.2 days (SD 12.7). The 66 patients who considered the waiting time too long underwent gastroscopy within 15 days. We made 5 diagnoses of esophageal and gastric tumour and gastric ulcer (7.6%) among the expedite list patients and 14 (4.6%) among those on the normal list (p=0.31). On including duodenal peptic disease in the analysis, the total prevalence rate rose to 19.7% in the short-wait group and to 10.4% (p=0.036) in the longer-wait group. DISCUSSION AND CONCLUSIONS: Our data suggests that asking to be fast-tracked does not have prognostic impact on the diagnosis of a major (gastric ulcer and cancer) pathology.

Difficult colonoscopies in the propofol era.

BACKGROUND: To study the relationship between endoscopic practice and adverse events during colonoscopy under standard deep sedation induced and monitored by an anesthetist. METHODS: We investigated the routine activity of an endoscopy center at the Padova University teaching hospital. We considered not only endoscopic and cardiorespiratory complications, but also the need to use high-dose propofol to complete the procedure, and the inability to complete the procedure. Variables relating to the patient's clinical conditions, bowel preparation, the endoscopist's and the anesthetist's experience, and the duration of the procedure were input in the model. RESULTS: 617 procedures under deep sedation were performed with a 5% rate of adverse events. The average dose of propofol used was 2.6 ± 1.2 mg/kg. In all, 14 endoscopists and 42 anesthetists were involved in the procedures. The logistic regression analysis identified female gender (OR=2.3), having the colonoscopy performed by a less experienced endoscopist (OR=1.9), inadequate bowel preparation (OR=3.2) and a procedure lasting longer than 17.5 minutes (OR=1.6) as the main risk factors for complications. An ASA score of 2 carried a 50% risk reduction (OR=0.5). DISCUSSION AND CONCLUSIONS: Our model showed that none of the variables relating to anesthesiological issues influenced which procedures would prove difficult.

An Item Response Theory-Based Scoring of the South Oaks Gambling Screen-Revised Adolescents.

The South Oaks Gambling Screen-Revised Adolescent (SOGS-RA) is one of the most widely used screening tools for problem gambling among adolescents. In this study, item response theory was used for computing measures of problem gambling severity that took into account how much information the endorsed items provided about the presence of problem gambling. A zero-inflated mixture two-parameter logistic model was estimated on the responses of 4,404 adolescents to the South Oaks Gambling Screen-Revised Adolescent to compute the difficulty and discrimination of each item, and the problem gambling severity level (θ score) of each respondent. Receiver operating characteristic curve analysis was used to identify the cutoff on the θ scores that best distinguished daily and nondaily gamblers. This cutoff outperformed the common cutoff defined on the sum scores in identifying daily gamblers but fell behind it in identifying nondaily gamblers. When screening adolescents to be subjected to further investigations, the cutoff on the θ scores must be preferred to that on the sum scores.

Maximizing the general success of cecal intubation during propofol sedation in a multi-endoscopist academic centre.

BACKGROUND: Achieving the target of 95% colonoscopy completion rate at centres conducting colorectal screening programs is an important issue. Large centres and teaching hospitals employing endoscopists with different levels of training and expertise risk achieving worse results. Deep sedation with propofol in routine colonoscopy could maximize the results of cecal intubation. METHODS: The present study on the experience of a single centre focused on estimating the overall completion rate of colonoscopies performed under routine propofol sedation at a large teaching hospital with many operators involved, and on assessing the factors that influence the success rate of the procedure and how to improve this performance, analyzing the aspects relating to using of deep sedation. Twenty-one endoscopists, classified by their level of specialization in colonoscopic practice, performed 1381 colonoscopies under deep sedation. All actions needed for the anaesthesiologist to restore adequate oxygenation or hemodynamics, even for transient changes, were recorded. RESULTS: The "crude" overall completion rate was 93.3%. This finding shows that with routine deep sedation, the colonoscopy completion rate nears, but still does not reach, the target performance for colonoscopic screening programs, at centers where colonoscopists of difference experience are employed in such programs.Factors interfering with cecal intubation were: inadequate colon cleansing, endoscopists' expertise in colonoscopic practice, patients' body weight under 60 kg or age over 71 years, and the need for active intervention by the anaesthesiologist. The most favourable situation--a patient less than 71 years old with a body weight over 60 kg, an adequate bowel preparation, a "highly experienced specialist" performing the test, and no need for active anaesthesiological intervention during the procedure--coincided with a 98.8% probability of the colonoscopy being completed. CONCLUSIONS: With routine deep sedation, the colonoscopy completion rate nears the target performance for colonoscopic screening programs, at centers where colonoscopists of difference experience are employed in such programs. Organizing the daily workload to prevent negative factors affecting the success rate from occurring in combination may enable up to 85% of incomplete procedures to be converted into successful colonoscopies.

Pathways connecting socioeconomic variables, substance abuse and gambling behaviour: a cross-sectional study on a sample of Italian high-school students.

OBJECTIVES: The aim of this study was to elucidate the pathway of associations linking gambling, alcohol intake, smoking habit, cannabis consumption between each other and with demographic and socioeconomic variables. SETTING AND PARTICIPANTS: A survey was conducted in 2017 on a representative sample of 15 602 Italian 14-year-olds to 17-year-olds attending 201 secondary schools. OUTCOME MEASURES: Structural Equation Models analysis was used to assess the pathway between gambling, alcohol intake, smoking, cannabis consumption, demographics and socioeconomic factors. RESULTS: Irrespective of socioeconomic or demographic variables, gambling is positively associated with alcohol and cannabis consumption, while cannabis consumption is predicted by smoking and by alcohol intake, smoking is predicted by alcohol intake. Adolescents with a higher weekly income are more at risk of gambling, drinking alcohol and smoking, while the degree of economic dissatisfaction was positively associated with alcohol intake, cannabis consumption and smoking. Maternal employment appeared to be positively associated with adolescents' smoking, alcohol intake and cannabis consumption. CONCLUSIONS: This is one of the first studies to shed light on the pathways of associations connecting various health-risk behaviours among adolescents with demographic and socioeconomic factors.

Factors influencing challenging colonoscopies during anesthesiologist-assisted deep sedation.

BACKGROUND/AIM: Increased demand for colon cancer screening procedures can significantly impact on routine colonoscopy management at dedicated facilities, prompting a review of the factors that can negatively affect workflow. Although potential adverse effects and impact on costs of deep sedation have been documented elsewhere, this study focuses on variables that can influence performance of colonoscopy in deep sedation and interfere with normal procedure scheduling in settings where the presence of an anesthesiologist is mandatory. PATIENTS AND METHODS: We performed a cross-sectional study of the activities of a colonoscopy screening unit, applying Bayesian Network (BN) analysis, designed to assess interdependencies among variables that can affect a process in complex, multidimensional systems. The study was performed at a teaching hospital where endoscopists and anesthesiologists of varying work experience operate on a rota basis. During a six-month period, we analyzed 1485 consecutive colonoscopies performed under deep propofol sedation, administered by an anesthesiologist via hand-controlled syringe. The BN was constructed with the variables: Gender, age, ASA status, bowel preparation, baseline blood pressure, endoscopist's experience, anesthesiologist's experience, presence of polypectomy, and the target node, "challenging procedure." This previously undefined category refers to any events disrupting the scheduled rota. RESULT AND CONCLUSION: Two distinct networks were identified. One deals mainly with relationships among the variables, patients' demographic and clinical characteristics (procedures with polypectomy, ASA and baseline blood pressure). The other explains relationships among the variables, "challenging procedure," bowel preparation, and endoscopist's experience. The factors associated with the anesthesiologist's activity do not influence challenging colonoscopies.

Population surveys compared with wastewater analysis for monitoring illicit drug consumption in Italy in 2010-2014.

BACKGROUND: Monitoring consumption by population surveys (PS) is an important way to challenge the spread of illicit drugs (ID). To improve the information, we explored a complementary method, particularly wastewater analysis (WWA). METHODS: We estimated the prevalence of use by PS, and the consumption by WWA, of cocaine, opioids, cannabis, methamphetamine and MDMA (ecstasy) from 2010 to 2014 in Italy and compared the results. RESULTS: According to PS, cannabis and cocaine were the ID most used in Italy (last month prevalence 3.0% and 0.43% respectively in 2010) followed by opioids (0.17%) and amphetamines (0.14%). WWA gave similar findings, with cannabis consumption (4.35 g THC/day/1000 inhabitants) exceeding cocaine (0.78 g), heroin (0.092 g), methamphetamine and MDMA (0.103 g). The time trend investigated by PS showed significant decreases for all ID from 2010 to 2012. WWA also indicated a reduction of consumption for methamphetamine (p<0.0001) and heroin (p<0.01). Both methods showed an increase for cannabis in 2014 (p<0.001) with the other ID unchanged. Spatial investigations by WWA showed that cannabis and cocaine were consumed significantly more in central Italy than in the north and south. PS indicated the same but only for cannabis. WWA was helpful to study weekly patterns of consumption, showing increases in cocaine and MDMA at weekends. CONCLUSIONS: PS and WWA were confirmed as complementary methods and when used together improved the information on ID use in Italy. We suggest that the combined use of the two approaches can give better information on ID use in the population.

Emerging trends in consuming behaviours for non-controlled substances by Italian urban youth: a cross sectional study.

INTRODUCTION: We investigated emerging trends in consuming behaviours for non-controlled substances in a cross sectional study on urban Italian adolescents and young adults, the reasons for consumption and risk perception as function of age, the relation with lifestyles and finally risk factors associated. METHODS: The survey methodology involved the administration of an anonymous questionnaire. It consisted of 68 questions, divided into five sections: personal details, socioeconomic characteristics, family and peer group, free time and lifestyles, and substances use. RESULTS: A total of 2621 adolescents and young adults (14-35 years old) from seven different Italian cities answered the questionnaire. The substances examined were mainly used recreationally (alcohol, energy drinks and smart-drugs) or to improve physical and sexual performance (physical performance-enhancing drugs, anabolic steroids and male sexual enhancement). The knowledge of the health related harm arising from the use of these products was very high for alcohol (> 90%), high for smart-drugs (> 70%), but significantly lower for anabolic steroids, drugs for sexual enhancement (~ 60%), physical performance-enhancing drugs or energy drinks (~ 55%). The principal risks factors for consumption were: the influence of friends (OR: 8.8), attending recreational places (OR: 5.4) aged between 25-35 years (OR: 3.0), be male (OR: 2.5) and having a bad relationship with the mother (OR: 2.1). CONCLUSIONS: These results have implication for prevention and early intervention programs of "physically and psychologically enhancing" non controlled substances use, which similarly to what is frequently advised for classical illicit drugs should focus on information campaigns and awareness initiatives especially addressed to young male adults who go clubbing, live outside the family and showed closed links with peers.

Disability-free life expectancy: a cross-national comparison among Bulgarian, Italian, and Latin American older population.

OBJECTIVE: To present sociodemographic and health status harmonized variables constructed to evaluate cross-national differences in term of Disability Free Life Expectancy (DFLE) across different surveys. METHOD: The study comprises national surveys conducted in Bulgaria, Italy, and Latin America and the Caribbean. A homogeneous group of health determinants for the older population was created and the DFLE indicator based on Sullivan's method was developed considering the harmonized common variables on disability. RESULTS: For all countries, DFLE values decline as age increases for both sexes, with a pronounced decline among women. Regardless the native country, women always present higher Life Expectancy than men at each age; however, they live a higher percentage of these years with disability. DISCUSSION: Further research should be carried out with standardized instruments that allow a more direct comparison, along with measurements of the potential differences across countries, which could explain differences in disability prevalence and DFLE.

Multidimensional profiles of health status: an application of the grade of membership model to the world health survey.

BACKGROUND: The World Health Organization (WHO) conducted the World Health Survey (WHS) between 2002 and 2004 in 70 countries to provide cross-population comparable data on health, health-related outcomes and risk factors. The aim of this study was to apply Grade of Membership (GoM) modelling as a means to condense extensive health information from the WHS into a set of easily understandable health profiles and to assign the degree to which an individual belongs to each profile. PRINCIPAL FINDINGS: This paper described the application of the GoM models to summarize population health status using World Health Survey data. Grade of Membership analysis is a flexible, non-parametric, multivariate method, used to calculate health profiles from WHS self-reported health state and health conditions. The WHS dataset was divided into four country economic categories based on the World Bank economic groupings (high, upper-middle, lower-middle and low income economies) for separate GoM analysis. Three main health profiles were produced for each of the four areas: I. Robust; II. Intermediate; III. Frail; moreover population health, wealth and inequalities are defined for countries in each economic area as a means to put the health results into perspective. CONCLUSIONS: These analyses have provided a robust method to better understand health profiles and the components which can help to identify healthy and non-healthy individuals. The obtained profiles have described concrete levels of health and have clearly delineated characteristics of healthy and non-healthy respondents. The GoM results provided both a useable way of summarising complex individual health information and a selection of intermediate determinants which can be targeted for interventions to improve health. As populations' age, and with limited budgets for additional costs for health care and social services, applying the GoM methods may assist with identifying higher risk profiles for decision-making and resource allocations.
