Development and Validation of the Italian "Brief Five-Item Chronic Pain Questionnaire" for Epidemiological Studies.

Background: Chronic pain (CP) prevalence estimates addressing a wide phenotype are still quite fragmented and may vary widely due to the lack of standardized tools of investigation. There is an urgent need to update general population CP estimates. Methods: For this purpose, the Brief Five-item Chronic Pain Questionnaire was developed through experts' consultations for design and content validity assessment; literature analysis of measures used to investigate CP for general population surveys; understandability evaluation through a survey on a convenience sample of affected and non-affected individuals; reliability assessment by means of two double-wave online surveys carried out by the Italian Twin Registry; criterion and construct validity assessment through the third wave of the 2019 European Health Interview Survey (Ehis). Results: Key dimensions were defined to describe CP main aspects from a public health perspective. Literature analysis showed that validated questionnaires were rarely used to address important public health CP aspects. Understandability of the measure was good. Test-retest analyses showed adequate reliability of the measure: k values were at least "moderate" with highest values regarding CP "occurrence" and "intensity". Correlations of CP with well-known comorbidities (cancer, depression), and specific traits (age, education) as well as of CP and its intensity with "physical pain occurrence and intensity" detected in the Ehis 2019, confirmed, respectively, a good construct and criterion validity. Construct validity was also evaluated through the correlation between "perceived treatment effectiveness" and "interference of pain in daily life activities" as recorded in the Ehis 2019. Conclusion: The designed questionnaire is a brief self-administered measure, particularly suitable to detect persistent states of pain and related intensity in large-scale general population surveys by means of a first filtering item followed by four further items. It is, in fact, designed to detect CP possible underlying causes/triggers, drugs/treatments taking and frequency, and self-perceived effectiveness among CP sufferers. Further validation of the measure in different social and cultural contexts is desirable.

The Perceived Health Status from Young Adults to Elderly: Results of the MEHM Questionnaire within the CUORE Project Survey 2008-2012.

Improving healthy life years requires an effective understanding and management of the process of healthy ageing. Assessing the perceived health status and its determinants is a relevant step in this process. This study explored the potentialities of the Minimum European Health Module (MEHM) to cope with this critical issue. Investigation was conducted on 4798 Italian residents (49.7% women, aged 35-79 years), participating in the CUORE Project Health Examination Survey 2008-2012. The three MEHM questions-perceived health status, chronic morbidity and activity limitations-were examined also in association with living context, seasonality, marital status and level of education. A higher prevalence of health status negative perception was associated with older age (9% and 24% respectively in men and women aged 35-44 years; 46% and 61% respectively in men and women aged 75-79 years). In women, this negative perception was higher than in men in any age group, and reached 50% in the 65-69 age group, 10 years earlier than in men. For both sexes, the level of education had a strong impact on this negative perception (odds ratio 2.32 and 2.72 in men and women respectively), while "living alone" played a greater impact in women than in men. MEHM activity limitations subscale was as much as 30% higher for questionnaires answered during the hottest months. This study identified potential predictors of perceived health status in adults aged 35-79 years, which can be used to target interventions aimed at improving self-perceived health status.

Is the association between precarious employment and mental health mediated by economic difficulties in males? Results from two Italian studies.

BACKGROUND: Flexible employment is increasing across Europe and recent studies show an association with poor mental health. The goal of the current study is to examine this association in the Italian population to assess the possible mediating role of financial strain. METHODS: Data were obtained by two Italian cross-sectional studies (PASSI and HIS) aimed at monitoring the general population health status, health behaviours and determinants. Mental health status was assessed using alternatively two validated questionnaires (the PHQ-2 and the MCS-12 score) and Poisson regression models were performed to assess if precarious work was associated with poor mental health. A formal mediation analysis was conducted to evaluate if the association between precarious work and mental health was mediated by financial strain. RESULTS: The analyses were performed on 31,948 subjects in PASSI and on 21,894 subjects in HIS. A nearly two-fold risk of depression and poor mental health was found among precarious workers, compared to workers with a permanent contract, which was strongly mediated by financial strain. CONCLUSIONS: Even with the limitations of a cross-sectional design, this research supports that precarious employment contributes through financial strain to reduce the mental health related quality of life and to increase mental disorders such as symptoms of depression or dysthymia. This suggests that when stability in work cannot be guaranteed, it would be appropriate to intervene on the wages of precarious jobs and to provide social safety nets for ensuring adequate income.

[The inappropriateness in the use of female cancer screening tests in Italy: over- and under-utilization determinants]. / L'inappropriatezza nell'uso dei test di screening oncologici femminili in Italia: determinanti di sovra e sottoutilizzo.

OBJECTIVES: to identify the determinants of over and under-use of Pap test and mammography in the screening programme target population. DESIGN: cross-sectional study. SETTING E PARTICIPANTS: we used data from the National Health interview conducted by the Italian National Institute of Statistics in 2012-2013 obtaining nation-wide representative samples of the female resident population aged 25-64 years (No. 32,831; target age of Pap test) and 50-69 years (No. 16,459; target age of mammography). MAIN OUTCOME MEASURES: overall coverage: proportion of women in the target age with at least one test in lifetime; appropriate coverage: proportion of women reporting to have at least one or more tests following the first one with the recommended frequency (three and two years for Pap test and mammography, respectively); over-use: women reporting to repeat test at higher frequency; under-use: women reporting not having ever had a test or having test at longer intervals. For frequency outcomes, only women aged 28-64 years and 52-69 years were included for Pap test and mammography, respectively. RESULTS: 11.9% of women have Pap test at the recommended frequency, 48.5% at shorter intervals, and 19.6% at longer intervals than recommended, while 20.0% never had a Pap test at all (39.6% under-use). 41.1% of women have a mammography at the recommended interval, 18.4% at shorter intervals, and 20.2% at longer intervals, while 20.3% never had a mammography at all. For both tests, in the North-East higher appropriate coverage and less over-use are observed, while in the South more under-use is highlighted. Young, foreigners, single, less educated, and unoccupied women have, at the same time, more over- and under-use for Pap test. Foreigner women reporting economic difficulties and single women have more mammography over and under-use. CONCLUSIONS: Pap test and, in a minor measure, mammography over-use are relevant in Italy, while large part of the population is still not covered.

Geographical and socioeconomic differences in uptake of Pap test and mammography in Italy: results from the National Health Interview Survey.

OBJECTIVE: The Italian National Health Service instituted cervical and breast cancer screening programmes in 1999; the local health authorities have a mandate to implement these screening programmes by inviting all women aged 25-64 years for a Pap test every 3 years (or for an Human Papilloma Virus (HPV) test every 5 years) and women aged 50-69 years for a mammography every 2 years. However, the implementation of screening programmes throughout the country is still incomplete. This study aims to: (1) describe cervical and breast cancer screening uptake and (2) evaluate geographical and individual socioeconomic difference in screening uptake. METHODS: Data both from the Italian National Health Interview Survey (NHIS) conducted by the National Institute of Statistics in 2012-2013 and from the Italian National Centre for Screening Monitoring (INCSM) were used. The NHIS interviewed a national representative random sample of 32 831 women aged 25-64 years and of 16 459 women aged 50-69 years. Logistic multilevel models were used to estimate the effect of socioeconomic variables and behavioural factors (level 1) on screening uptake. Data on screening invitation coverage at the regional level, taken from INCSM, were used as ecological (level 2) covariates. RESULTS: Total 3-year Pap test and 2-year mammography uptake were 62.1% and 56.4%, respectively; screening programmes accounted for 1/3 and 1/2 of total test uptake, respectively. Strong geographical differences were observed. Uptake was associated with high educational levels, healthy behaviours, being a former smoker and being Italian versus foreign national. Differences in uptake between Italian regions were mostly explained by the invitation coverage to screening programmes. CONCLUSIONS: The uptake of both screening programmes in Italy is still under acceptable levels. Screening programme implementation has the potential to reduce the health inequalities gap between regions but only if uptake increases.

[Self-perceived health status among immigrants in Italy]. / Capitolo 2: Lo stato di salute percepito della popolazione immigrata in Italia.

OBJECTIVES: to evaluate self-perceived health status of immigrants in Italy. DESIGN: cross-sectional study based on the representative national samples of the multipurpose surveys "Health conditions and use of health services" conducted in 2005 and 2013 by the Italian National Institute of Statistics (Istat). SETTING AND PARTICIPANTS: the study was conducted on the age group of 18-64: No. 80,661 in 2005, among which 3.2% were immigrants, and No. 72,476 in 2013, among which 7.1% were immigrants. MAIN OUTCOME MEASURES: prevalence rate ratios (PRR) calculated through log-binomial regression models, stratified by survey edition and gender, by evaluating the association between the Physical Component Score (PCS), the Mental Component Score (MCS), and the overall health index and citizenship. Adjustment for the following confounding factors was performed: age, educational level, working condition, perceived economic resources, body mass index (BMI). RESULTS: in 2005, immigrants had a lower probability of poor-perceived physical health, both among men (PRR: 0.79; 95%CI 0.70-0.89) and women (PRR: 0.89; 95%CI 0.82- 0.97), compared to Italians. In 2013, the perceived health advantage of immigrants was reduced for both genders (PRR males: 0.87; 95%CI 0.80-0.95; PRR females: 0.94; 95%CI 0.88-0.99). In the considered period, the prevalence of people with worse mental health conditions increases, with lower PRR among immigrants, compared to Italians. Higher probability of «NOT good¼ overall perceived health was also observed among immigrants residing in Italy for at least 10 years (PRR men: 1.24; PRR women: 1.15) and among immigrants men from America (PRR: 1.35). CONCLUSIONS: from 2005 to 2013, immigrants seemed to maintain a better perception of health status than Italians. Nevertheless, study results show a decrease in self-perceived health, particularly mental health, in the considered period - apart from demographic, socioeconomic, and lifestyle factors - as well as a worse overall self-perceived health status among immigrants who stayed in Italy longer. Such results lead to suppose that the "healthy migrant effect" tends to disappear over time, maybe due to the world financial crisis. Unemployment increases and lower income also made the access to medical care more difficult, particularly among the most fragile population groups, including migrants. In this context, it is essential to promote health policies supporting equity of access to healthy lifestyles and effective health services, which are fundamental to reduce health inequalities.

[Cervical and breast cancer screening among immigrant women resident in Italy]. / Capitolo 3: La prevenzione dei tumori femminili nelle donne immigrate residenti in Italia.

OBJECTIVES: to compare Pap test and mammography uptake in 2005 and 2013 between Italian and immigrant women residing in Italy and to evaluate factors associated with probability of being up-to-date with screening testing in immigrant women. DESIGN: cross-sectional study based on data of "Multipurpose survey on health and use of health services" conducted in 2005 and 2013 by the Italian National Institute of Statistics (Istat). SETTING AND PARTICIPANTS: the analysis includes the interviews of women included in the target age group for Pap test (25-64 years: No. 32,831) and mammography (50- 69 years: No. 16,459). Women resident in Italy with foreign citizenship are defined as "immigrants". MAIN OUTCOME MEASURES: standardized prevalence rates of women self-reporting having had a Pap test and a mammography in the absence of symptoms "at least once in a lifetime"; standardized prevalence ratio of up-to-date test uptake according to recommendation, i.e., in the last three years for Pap test and two years for mammography. A logistic regression model has been built to evaluate the association between up-to-date test uptake and demographic, socioeconomic, behavioural, and health service utilization factors in immigrant women. RESULTS: prevalence of Pap test and mammography uptake was lower in immigrants, both in 2005 and 2013. This difference reduced in 2013 due to a stronger increase in immigrants than in Italians, except for mammography. The increase in Pap test uptake among immigrant women was stronger in North-Eastern (+26,4%) and Central Italy (+26,4%), while in Southern Italy and in the Islands the increase was stronger among Italian women. Test uptake in immigrants increases with longer length of stay in Italy for both tests. Among immigrants (No. 2,601), Pap test uptake was higher in women who: had a preventive examination in the previous month (OR: 2.13); have an Italian partner (OR: 1.72); have been staying in Italy for more than 13 years; are graduated (OR: 1.87); perceive their economic resources as adequate or optimal (OR: 1.39); come from the Americas (68% more if compared to Africans). As regards mammography uptake in immigrants (No. 636), associated factors are: having had a preventive examination in the previous month (OR: 3.35); having high educational level (OR: 2.51); perceiving economic resources as adequate or optimal (OR: 1.75). CONCLUSION: this study shows that there is a lower screening uptake in immigrant women, as observed in other studies conducted both in Italy and in industrialized Countries, even with longer history of immigration. In the South of Italy, the uptake is very low also for Italian women, with prevalence lower than immigrants in Northern Italy. This phenomenon suggests that high accessibility to screening facilities is effective in increasing uptake in both Italian and immigrant women. The decreasing trend in differences with longer lengths of stay, the improvement in 2013 compared to 2005, and the advantage of women with Italian partners suggest a positive effect of integration on preventive behaviours, even if there are differences between immigrants' areas of origin.

[Factors associated to medical visits: comparison among Italians and immigrants resident in Italy]. / Capitolo 6: Fattori associati al ricorso a visite mediche: confronto tra cittadini italiani e stranieri residenti in Italia.

OBJECTIVES: to evaluate the role of factors potentially associated with the use of medical visits by the immigrant population living in Italy, making a comparison with the Italian population. DESIGN: cross-sectional study based on the representative sample of the population residing in Italy considered in the Survey "Health and use of health services" conducted by the Italian National Institute of Statistics (Istat) in 2013. SETTING AND PARTICIPANTS: the study was conducted on a sample of citizens aged 18-64 years (72,476 individuals) representing a population of 37,290,440 residents in Italy (33.9 million Italians and 3,390,440 foreigners) in 2013. MAIN OUTCOME MEASURES: an indicator on the use of medical visits has been used as an outcome, based on people who had replied affirmatively to the question: «In the last four weeks, have you been examined by the family doctor, by the pediatrician, or by medical specialists, as an eye doctor, dentist, etc.?¼. Starting from this outcome, the question «Can you indicate the main reason of the visits made in the last 4 weeks?¼ was used to build two additional outcome variables for separately evaluating the use of medical examinations for "diseases or disorders" from the use of medical examination for "health check in the absence of diseases or disorders". For each outcome, a logistic regression model was fitted, considering as independent variables information related to socioeconomic status and to the respondent's health condition. RESULTS: 21.4% of foreigners (18-64 years) living in Italy used medical visits during the four weeks before the interview, a percentage lower than the one recorded among Italian citizens (27.0%). Taking into account the socioeconomic characteristics, lifestyle and health status of respondents, the results of logistic regression models showed that foreigners have a lower probability than Italians to make a medical examination, both for visits motivated by any health problems (OR: 0.80; 95%CI 0.73-0.87), and in case of medical examination carried out for preventive purposes (OR: 0.72; 95%CI 0.64-0.82). CONCLUSION: the more the time living in the host Country increases, the more immigrants residing in Italy tend to have the same health problems of the most disadvantaged groups of the autochthonous population, maybe beacuse of the deterioration of the so-called "healthy immigrant effect". In this context, they should be considered as more vulnerable in terms of health, and special attention must be paid to prevention. The lower use of medical visits highlights inequities in access to services. In order to reduce health inequalities, barriers that affect equitable access to health care should be removed, taking into account the heterogeneity of these sub-groups, characterized by different cultures and attitudes towards the health system.

[Differences in influenza vaccination coverage among subgroups of adult immigrants residing in Italy at risk for complications (2012-2013)]. / Capitolo 7: Differenze nella copertura vaccinale antinfluenzale tra sottogruppi di immigrati adulti residenti in Italia a rischio di complicanze (2012-2013).

OBJECTIVES: to evaluate differences in influenza vaccination coverage (IVC) in immigrants at risk for influenza-related complications, according to their area of origin and length of stay in Italy. DESIGN: cross-sectional survey conducted on the sample of foreign citizens included in the survey on health conditions and use of health services of the Italian resident population (Italian national institute of statistics, 2012-2013). SETTING AND PARTICIPANTS: analysis conducted on 885 foreign adult citizens (≥18 years) at risk for influenza-related complications (elderly residents ≥65 years and residents with specific chronic diseases). MAIN OUTCOME MEASURES: vaccination coverage ratios (VCR) comparison between long-term immigrants (≥10 years) and recent immigrants (<10 years), and between non-African and African immigrants, adjusted by demographic and socioeconomic characteristics and level of health services utilization. RESULTS: IVC among immigrants was 15.6%, significantly higher in long-term immigrants (18.3%) compared to recent immigrants (10.2%) (VCR: 1.79; 95%CI 1.21-2.66), and in non-African immigrants (17.1%) compared to African immigrants (9.4%) (VCR: 1.82; 95%CI 1.04-3.17). After adjusting on the basis of demographic and socioeconomic characteristics and for level of health services utilization between the compared subgroups, the difference in IVC according to the length of stay was greatly reduced (VCR: 1.41; 95%CI 0.94- 2.10), while IVC difference reduction according to area of origin was less relevant (VCR: 1.66; 95%CI 0.95-2.91). CONCLUSIONS: demographic and socioeconomic characteristics and level of health services utilization explained part of the difference in IVC between the compared subgroups, particularly between long-term and recent immigrants. The difference in IVC between African immigrants and immigrants from other areas remained quite pronounced even after adjusting on the basis of these factors. This suggests that IVC, especially in African immigrants, is affected by other informal barriers, such as cultural and linguistic barriers, that need to be addressed when planning effective immunization access strategies.

The variation in the health status of immigrants and Italians during the global crisis and the role of socioeconomic factors.

BACKGROUND: The effects of the recent global economic and financial crisis especially affected the most vulnerable social groups. Objective of the study was to investigate variation of self-perceived health status in Italians and immigrants during the economic global crisis, focusing on demographic and socioeconomic factors. METHODS: Through a cross-sectional design we analyzed the national sample of multipurpose surveys "Health conditions and use of health services" (2005 and 2013) conducted by the Italian National Institute of Statistics (ISTAT). Physical Component Summary (PCS) and Mental Component Summary (MCS) scores, derived from SF-12 questionnaire, were assumed as study outcome, dichotomizing variables distribution at 1st quartile. Prevalence rate ratios (PRR) were estimated through log-binomial regression models, stratified by citizenship and gender, evaluating the association between PCS and MCS with surveys' year, adjusting for age, educational level, employment status, self-perceived economic resources, smoking habits, body mass index. RESULTS: From 2005 to 2013 the proportion of people not employed or reporting scarce/insufficient economic resources increased, especially among men, in particular immigrants. Compared with 2005 we observed in 2013 among Italians a significant lower probability of worse PCS (PRR = 0.96 both for males and females), while no differences were observed among immigrants; a higher probability of worse MCS was observed, particularly among men (Italians: PRR = 1.26;95%CI:1.22-1.29; immigrants: PRR = 1.19;95%CI:1.03-1.38). Self-perceived scarce/insufficient economic resources were strongly and significantly associated with worse PCS and MCS for all subgroups. Lower educational level was strongly associated with worse PCS in Italians and slightly associated with worse MCS for all subgroups. Being not employed was associated with worse health status, especially mental health among men. CONCLUSIONS: Our findings support the hypothesis that economic global crisis could have negatively affected health status, particularly mental health, of Italians and immigrants. Furthermore, results suggest socioeconomic inequalities increase, in economic resources availability dimension. In a context of public health resources' limitation due to financial crisis, policy decision makers and health service managers must face the challenge of equity in health.

Differences in Influenza Vaccination Coverage between Adult Immigrants and Italian Citizens at Risk for Influenza-Related Complications: A Cross-Sectional Study.

BACKGROUND: Due to their increased vulnerability, immigrants are considered a priority group for communicable disease prevention and control in Europe. This study aims to compare influenza vaccination coverage (IVC) between regular immigrants and Italian citizens at risk for its complications and evaluate factors affecting differences. METHODS: Based on data collected by the National Institute of Statistics during a population-based cross-sectional survey conducted in Italy in 2012-2013, we analysed information on 42,048 adult residents (≥ 18 years) at risk for influenza-related complications and with free access to vaccination (elderly residents ≥ 65 years and residents with specific chronic diseases). We compared IVC between 885 regular immigrants and 41,163 Italian citizens using log-binomial models and stratifying immigrants by area of origin and length of stay in Italy (recent: < 10 years; long-term: ≥ 10 years). RESULTS: IVC among all immigrants was 16.9% compared to 40.2% among Italian citizens (vaccination coverage ratio (VCR) = 0.42, 95% confidence interval (CI): 0.36-0.49). Adjusting for sex, age and area of residence, this difference was greatly reduced but remained statistically significant (VCR = 0.71, 95 CI: 0.61-0.81). Further adjustment for socio-economic factors (education, occupation, family composition and economic status) and a composite indicator of health-services utilization did not affect the difference (VCR = 0.78, 95% CI: 0.68-0.90). However, after adjustments, only long-term immigrants from Africa (VCR = 0.49, 95% CI: 0.28-0.85) and recent immigrants (VCR = 0.58, 95% CI: 0.43-0.78) showed a significantly different IVC compared to Italian citizens. CONCLUSIONS: Differences in demographic characteristics, socio-economic conditions and health-services utilization explained the reduced IVC in most long-term immigrants compared to Italian citizens. By contrast, these differences did not explain the reduced IVC in long-term immigrants from Africa and recent immigrants. This suggests that IVC in these sub-groups is affected by other informal barriers (e.g., cultural and linguistic) that need to be investigated to promote effective immunization access strategies.

Health observation compared to health reporting: findings from a pilot study in Florence.

PURPOSE: Both health interview surveys (HISs) and health examination surveys (HESs) are used to describe the health status of populations. In Italy, to determine the feasibility of conducting a national-level HES, a pilot HES was conducted in the city of Florence among participants of a previous national-level HIS. The aim of the present analysis was to compare the results of the two surveys. METHODS: The study population consisted of the 343 Florence residents 35 to 74 years of age who participated in both surveys (sample drawn with probabilistic criteria). We compared the self-reported HIS data to the HES health measurements for diabetes, hypertension, osteoporosis, smoking, height, weight, and body mass index. For categorical variables, contingency tables were used, calculating symmetric and asymmetric indices. For the continuous variables, Student's t test for matched samples was used. RESULTS: The prevalence of the most important pathologic conditions and risk factors determined with HES measurements was significantly higher than that based on self-reported HIS data. CONCLUSIONS: The results stress that individuals have poor knowledge of their own health; therefore health measurements need to be taken.

[Differences of perceived health and lifestyle by occupational groups in the Italian ISTAT (Central Statistic Institute) health survey]. / Differenze occupazionali nello stato di salute e negli stili di vita nell'indagine ISTAT sulla salute 1999-2000.

BACKGROUND: Little is known about the distribution by occupation of chronic illness, disability, morbidity, and lifestyles which put health at risk. OBJECTIVES: To provide a map of the social inequalities in various dimensions of health and lifestyle by social class and for specific occupational groups. To formulate a hypothesis about the mechanisms which generate these inequalities. METHODS: Prevalence rate ratios and prevalence odds ratios of perceived health, chronic illness, disability, absenteeism, trauma, smoking, and obesity calculated with data from the 1999-2000 Italian ISTAT (Central Statistics Institute) health survey; the study population includes adults (aged over 18 years) employed, or searching for a job, or withdrawn from the workforce. RESULTS: Among workers in manual unskilled labour, construction and agriculture are noted for worse health and more unhealthy lifestyles than average. For example, perceived bad health is more widespread among agricultural labourers (OR = 1.63), masons and construction machine operators (OR = 1.75), transport drivers (OR = 1.40), male caretakers, custodians, janitors and domestic help (OR = 1.46), electro-technicians (OR = 1.44), leatherworkers and shoemakers (OR = 3.58), miners and quarrymen (OR = 2.60), earthenware and stone workers (OR = 2.14), garment and furnishings workers (OR = 1.86); in female workers excess risk for perceived bad health was present among agricultural labourers (OR = 2.08), caretakers, custodians, janitors and domestic helpers (OR = 1.49), waitresses, cooks and bartenders, (OR = 1.44), and textile workers (OR = 1.67). Smoking was more widespread among chemical workers (OR = 1.41), and in miners and quarrymen (OR = 1.30). An excess risk of smoking of 20-25% was evident in spinners, weavers and finishers; masons, (and) builders; waiters, cooks and bartenders; garment and furnishings workers; porters and warehouse workers. The risk was 10% higher among foundry workers and forgers, plumbers, carpenters and welders, and transport drivers. Among women the propensity to smoke was higher among waitresses, cooks and bartenders (OR = 1.37), cleaners, commerce and service workers (OR = 1.22). Other occupational groups with an increased smoking prevalence, where women were less represented, included: chemical workers (OR = 2.25), butchers (OR = 1.97), postwomen (OR = 1.58), plastics workers (OR = 1.56), shippers (OR = 1.37). CONCLUSIONS: It can be hypothesized on the one hand that there are factors and mechanisms common to the various occupational groups belonging to the same social class; on the other, there are factors and mechanisms specific to certain occupational categories. The latter can generate specific health subcultures. A greater integration between qualitative and quantitative research is recommended, which would yield better explanations of the observed inequalities.

[Characteristics of unconventional medicine users and their households in Italy]. / Caratteristiche individuali e familiari degli utilizzatori di terapie non convenzionali in Italia.

The results presented in this paper are part of the largest survey on unconventional medicine conducted so far (more than 140 000 people). Families with high socio-economical levels had the highest probability of choosing unconventional medicine. The use is strongly related to geographic area probably due to different availability of structures able to provide these therapies. At individual level the choice to use unconventional medicine seems a "cultural" trend associated with healthy life styles, and with positive attitudes towards prevention. It is interesting also to underline that the use of unconventional medicine is more frequent among women. Almost all users of unconventional medicine (80%) declare to be in good health, and this can indicate that unconventional therapies are mostly used for not serious and self limited conditions. Furthermore, use of unconventional medicine is often associated with a greater use of conventional drugs and with a greater frequency of check-up. This suggests a "complementary", more than "alternative" use of this kind of therapies.

Use of unconventional medicine in Italy: a nation-wide survey.

OBJECTIVE: To investigate the prevalence of use of unconventional therapies in Italy, the main health problems associated with and the motivations for use of these therapies. METHODS: Questions about the use of unconventional therapies were inserted in a nation-wide survey conducted by face-to-face interviews with all members of sampled families by the National Institute of Statistics during four quarters of the years 1999-2000. Data presented here are based on the results of the first two quarters of the survey (September and December 1999) during which a representative sample of 30,000 Italian families (70,898 individuals) was interviewed. RESULTS: Almost 9 million people (15.6% of the Italian population) used at least one unconventional therapy during the period 1997-1999. Homeopathy was the most frequently used (8.2% of the population), followed by manual treatments (7%), herbal medicine (4.8%) and acupuncture (2.9%). Homeopathy was also quite commonly used by children (7.7% of Italian children). The main reason for use was concern about potential toxicity of "conventional medicine". The health problem most frequently treated with all kinds of unconventional therapies was pain. CONCLUSIONS: Use of unconventional therapies has almost doubled since 1991. However, with 15.6% of the Italian population (9 million people) using at least one therapy, Italy ranks among the "light" users compared with other European countries. Homeopathy is the most frequently used therapy. The typical user is, as in other western countries, a highly educated woman aged 35-44 years and resident in the richest part of the country (north-eastern Italy).
