RESUMO

AIM: To increase maintenance of breastfeeding through improved primary care support. METHOD: A cluster randomised controlled trial recruited 15 rural family doctor's offices and 330 women who were currently breastfeeding took part. Eight practices formed the intervention group (154 women) and seven formed the control group (176 women). The practice nurses who provided the intervention used a specially designed motivational flowchart to speak to the mothers when they brought their child for immunisation at 2, 4 and 6 months. The nurses also attended preparatory workshops on breastfeeding management, counselling skills, motivational interviewing and reflective practice and were given resources and support. Breastfeeding rates were measured at 4 and 6 months. RESULTS: Randomisation equally distributed all measured variables except prenatal intentions to rejoin employment within 12 months (70% intervention, 56% control, p < 0.05). After adjustment, the 4-month figures showed significantly higher rates of exclusive breastfeeding (OR 1.88; 95%CI 1.01-3.50; p = 0.047) and full breastfeeding (water/juice allowed) (OR 1.95; 95%CI 1.03-3.69; p = 0.04) in the intervention group. There were no differences at 6 months. CONCLUSION: A motivational interviewing intervention by primary care health professionals who have undertaken a replicable training programme is feasible and effective in increasing exclusive breastfeeding and full/predominant breastfeeding at 4 months.

RESUMO

INTRODUCTION: The quality of life (QoL) is an important outcome indicator for heart failure management. As the use of a validate questionnaire in a different cultural context can affect data interpretation our main objective is the Italian translation and linguistic validation of the Severe Heart Failure Questionnaire (SHF) and its comparison with the MLHF (Minnesota Living with Heart Failure) Questionnaire. METHODS: The SHF and "The Minnesota Living with Heart Failure Questionnaire" were translated. A consensus involving parallel back-translations was established among a group of cardiologists, psychologists and biostatisticians. SHF and MLHF were both administrated to a sample of 50 patients. RESULTS: The patients' median age was 63 years. Ace inhibitors therapy was administered in 88% of cases and betablockers in 56% of cases. Finally the Italian version of SHF correlates well with MLHF for all domains, except life satisfaction SHF domain. DISCUSSION: The Italian version of the SHF correlates well with MLHF for almost all domains and it represents a valid alternative for quality of life assessment in heart failure patients.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a condition associated with high morbidity, mortality and cost to the community. Patients often report symptomatic improvement with long acting beta-2 agonists (LABAs) and anticholinergic bronchodilator medications, both of which are recommended in COPD guidelines. These medications have different mechanisms of action and therefore theoretically could have an additive effect when combined. As these medications are prescribed in COPD as long term therapy, it is important to assemble reliable evidence on their relative and additive effects. OBJECTIVES: To compare the relative efficacy and safety of regular long term use (at least four weeks) of ipratropium bromide and LABA in patients with stable COPD. Comparisons were made between single agents and in combination versus LABAs alone. SEARCH STRATEGY: We searched the Cochrane Airways Group Specialised Register of Trials (August 2005) and reference lists of articles. We also contacted drug companies for relevant trial data. SELECTION CRITERIA: All randomised controlled trials comparing treatment for at least four weeks with an anticholinergic agent (ipratropium bromide) alone or in combination with LABA versus LABA alone, delivered via metered dose inhaler or nebuliser, in non-asthmatic adult subjects with stable COPD. DATA COLLECTION AND ANALYSIS: Three review authors independently performed data extraction and study quality assessment. We contacted study authors and pharmaceutical companies for missing data. MAIN RESULTS: Seven studies met the inclusion criteria of the review (2652 participants). Monotherapy comparison (six studies): There was a significantly greater change in favour of salmeterol in morning PEF and FEV1. There were no significant differences in quality of life, exacerbations, or symptoms. Formoterol appeared to confer some benefits over ipratropium treatment in terms of morning peak flow. Combination comparison (three studies): There was a significant improvement in post-bronchodilator lung function, supplemental short-acting beta-agonist use and HRQL in favour of combination therapy compared with salmeterol alone. AUTHORS' CONCLUSIONS: The available data from the trials suggest that there is little difference between regular long term use of IpB alone and salmeterol if the aim is to improve COPD symptoms and exercise tolerance. However, salmeterol was more effective in improving lung function variables. In terms of post-bronchodilator lung function, combination therapy conferred modest benefits and a significant improvement in HRQL, and reduced supplemental short-acting beta-agonist requirement, although this effect was not consistent. Additional studies are needed to assess the relative effects of combining therapies, using validated subjective measurements, and should consider concordance and the convenience of people having to use different inhaler devices.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a condition associated with high morbidity, mortality and cost to the community. Patients often report symptomatic improvement with short-acting beta-2 agonists (SABA) and anticholinergic bronchodilator medications, and both are recommended in COPD guidelines. These medications have different mechanisms of action and therefore could have an additive effect when combined. OBJECTIVES: To compare the relative efficacy and safety of regular long term use (at least four weeks) of ipratropium bromide and short- acting beta-2 agonist therapy in patients with stable COPD. SEARCH STRATEGY: The Cochrane Airways Group Specialised Register of Trials was searched. Bibliographies were checked to identify relevant cross-references. Drug companies were contacted for relevant trial data. The searches are current to August 2005. SELECTION CRITERIA: All randomised controlled trials comparing at least 4 weeks of treatment with an anticholinergic agent (ipratropium bromide) alone or in combination with a beta-2 agonist (short acting) versus the beta-2 agonist alone, delivered via metered dose inhaler or nebuliser, in non-asthmatic adult subjects with stable COPD. DATA COLLECTION AND ANALYSIS: Data extraction and study quality assessment was performed independently by three reviewers. Authors of studies and relevant manufacturers were contacted if data were missing. MAIN RESULTS: Eleven studies (3912 participants) met the inclusion criteria of the review. Small benefits of ipratropium over a short-acting beta-2 agonist were demonstrated on lung function outcomes. There were small benefits in favour of ipratropium on quality of life (HRQL), as well as a reduction in the requirement for oral steroids. Combination therapy with ipratropium plus a short-acting beta-2 agonist conferred benefits over a short-acting beta-2 agonist alone in terms of post-bronchodilator lung function. There was no significant benefit of combination therapy in subjective improvements in HRQL, but again there was a reduction in the requirement for oral steroids. AUTHORS' CONCLUSIONS: The available data from the trials included in this review suggest that the advantage of regular long term use of ipratropium alone or in combination with a short-acting beta-2 agonist or over a beta-2 agonist alone are small, if the aim is to improve lung function, symptoms and exercise tolerance. Until further data are available, the strategy of providing a short-acting beta-2 agonist on a PRN basis, and then either continuing with the short-acting beta-2 agonist regularly or conducting an "n of 1" trial of regular beta-2 agonist or regular anticholinergic to determine the treatment that gives the best relief of symptoms (and continuing with it), would seem cost effective. This strategy does need formal evaluation. Patient preference is also important, as is the relative importance of avoiding the use of systemic corticosteroids.

RESUMO

We have examined the potential for cholesterol lowering in secondary prevention of coronary heart disease based on data from the European Action on Secondary Prevention through Intervention to Reduce Events (EUROASPIRE) study carried out in 1995-1996 in nine European centres (Czech Republic, Finland, France, Germany, Hungary, Italy, The Netherlands, Slovenia and Spain). Consecutive patients aged < or = 70 years in four diagnostic categories--coronary artery bypass grafting, percutaneous transluminal coronary angioplasty, acute myocardial infarction, and acute myocardial ischaemia without infarction--were identified from hospital records and invited for an interview and risk factor assessment at least 6 months after hospital admission. Plasma lipid measurements were carried out in a central laboratory. Combining patients from all centres and diagnostic categories (n = 2749) the medians (interquartile ranges) for plasma lipids were: total cholesterol 5.36 (4.76-6.03) mmol/l, high density lipoprotein (HDL) cholesterol 1.19 (1.01-1.42) mmol/l, triglycerides 1.55 (1.15-2.24) mmol/l, and low density lipoprotein (LDL) cholesterol 3.32 (2.76-3.91) mmol/l. Only 33% of the patients received lipid-lowering drugs. If the therapeutic goal given in the 1998 European recommendations, total cholesterol < 5.0 mmol/l, were applied, 67% of these patients would have needed an intensified cholesterol-lowering action, and with an even stricter goal, total cholesterol < 4.5 mmol/l, this proportion would have been as high as 84%.

RESUMO

BACKGROUND: Population-based data on coronary events are generally lacking for large areas, such as at the nation-wide level. While mortality data are currently and exhaustively collected in all developed countries and in a few developing countries, incidence and prevalence are often available only for certain subgroups of the population under study. METHODS: We propose to estimate population-based incidence and prevalence of coronary events through a mathematical method using mortality and survival data as input, and to forecast coronary event occurrence using an age, period and cohort approach. The method reconstructs incidence and prevalence of major coronary events in Italy from 1970 to 1997 and projects trends up to the year 2007 using survival data on coronary events from the Area Friuli-MONICA (MONItoring of CArdiovascular diseases) register. RESULTS: Major coronary event incidence has been decreasing since 1977 for men and since 1974, for women. Conversely, major coronary event prevalence increased up to the end of the 1980s for men and up to the early 1980s for women, and it has been declining thereafter. Major coronary event prevalence results from three main effects: increasing survival, population ageing, and incidence trend. CONCLUSIONS: Availability of national population data, collection of population-based survival data from the MONICA registers and appropriate statistical and mathematical methods help to estimate and project incidence and prevalence trends for major coronary events. This information is essential to plan and implement actions aimed at improving medical care services, and to evaluate the impact of public health interventions as well as spontaneously changing habits.

RESUMO

BACKGROUND: The human health effects of exposure to indoor nitrogen dioxide (NO2) are unclear, and few studies have examined the effects of short-term peak levels of exposure. METHODS: The association between indoor exposure to NO2 and respiratory illness was examined in 388 children aged 6-11 years. The NO2 levels were monitored during winter in 41 classrooms, from four schools with unflued gas heating and four schools with electric heating. Each classroom was monitored daily with 6-hour passive diffusion badge monitors over nine alternate weeks, and with hourly monitors over two of those weeks. Children living in homes with unflued gas appliances were also monitored daily over four evenings during times of gas use. RESULTS: Exposure to NO2 at hourly peak levels of the order of > or = 80 ppb, compared with background levels of 20 ppb, was associated with a significant increase in sore throat, colds and absences from school. An increase in cough with phlegm was marginally significant. Significant dose-response relationships were demonstrated for these four measures with increasing levels of NO2 exposure. CONCLUSIONS: Short-term peak levels of exposure are important to consider in relation to adverse respiratory effects associated with NO2 exposure.

RESUMO

BACKGROUND: The major objectives are to report on coronary event mortality, incidence and attack rates and changes over time observed in the Italian MONICA populations and to assess if trends are consistent when different disease definitions are considered. An analysis of diagnostic agreement between clinical and MONICA categories is presented in the context of developing a model for estimating disease incidence in a population, based on currently available data. METHODS: Data were provided by the three Italian MONICA (MONItoring trends and determinants of CArdiovascular diseases) registers. The areas of Brianza and Friuli, both located in northern Italy, completed the 10-year period of registration. Data from the MONICA Latina area, located close to Rome, were limited to the first 3 years of registration. These data are used for assessing geographical differences in rates in the mid- 1980s and estimating the diagnostic agreement between International Classification of Diseases (ICD) codes and MONICA categories. Two diagnostic aggregates have been used: the standard MONICA diagnostic definition for myocardial infarction (MI), which includes non-fatal definite myocardial infarction and fatal coronary events, and the coronary event definition which includes, in addition, non-fatal possible myocardial infarctions. RESULTS: From the mid-1980s to the mid-1990s, a considerable reduction in all-cause, cardiovascular and coronary mortality rates occurred in the monitored populations. Data from the MONICA registers confirm the accuracy of official reports of death rates and changes in Italy. Comparisons of time differences in attack and incidence rates of myocardial infarction and all coronary events indicate that the impact of the more severe manifestations of coronary heart diseases (fatal coronary event and acute MI) reduced during the period of observation, but when less severe events (minor myocardial infarction and angina pectoris) are considered, the overall impact of the disease on the population remained stable. CONCLUSION: Epidemiological surveillance of coronary syndromes is relevant over this time period of impressive changes in prevention and treatment. Continuing restrictions in available resources necessitate the development of simplified registration systems.

RESUMO

Over the last years--late 1970s to early 1990s--the incidence of prostate carcinoma has nearly doubled, even though many more patients die suffering from prostate cancer than because of it. This finding, together with the slow growth of this tumor and the absence of a controlled trial that would suggest a benefit from screening, makes early diagnosis of this disease quite questionable. On the other hand, it is well known that prostatic carcinoma is curable as long as it is intracapsular, and that there is an ever increasing encouragement to early detection in all diseases. The costs of screening and the difficulty in balancing the benefits of screening against its negative effects, such as psychological impact and overtreatment, must be taken into account as well. In our opinion, one of the advantages of early diagnosis should be that the patients' quality of life improves, because the stage at diagnosis and, as a result, the number of patients suffering from bone metastasis decrease, and unknown benign pathologies can be cured. These observations are not at all negligible. Our study aims to demonstrate that by using PSA as an initial test, the screening costs are reasonable and the disease incidence is just as expected.

RESUMO

OBJECTIVE: The aim of this ecological study was to examine the relationship between potential cyanobacterial exposure through drinking water during pregnancy and birth outcomes. METHOD: One hundred and fifty-six communities in South-Eastern Australia were involved, providing 32,700 singleton live newborn during the period 1992-94. Cyanobacterial occurrence and cell density (alert level) in drinking water sources during the first trimester, the total gestational period for premature births or limited to 36 weeks in term infants, and the last 12 weeks prior to preterm births or up to and including 36 weeks in term infants were used as estimates of exposure. RESULTS: There were statistically significant differences between the proportion of time during the first trimester with cyanobacterial occurrence and the percentage of births that were low birth weight (LBW) and very low birth rate (VLBW). Significant differences were also found among various categories of first trimester exposure based on average cell density and LBW, prematurity and congenital defects. However, the pattern of these results does not suggest a causal link to cyanobacteria. There were no clear dose-response relationships. Analyses based on exposure during the last 12 weeks and total gestation also showed no significant dose-response effects. CONCLUSION: The results of this study provide no clear evidence for an association between cyanobacterial contamination of drinking water sources and adverse pregnancy outcomes.

RESUMO

OBJECTIVES: To examine the prevalence of self-reported asthma, bronchitis/emphysema, wheezing, night cough and smoking in Port Adelaide; to explore the relationship of the disorders to the presence of industry, tobacco smoke, indoor appliances and air quality. METHODS: Prevalence data from a 1995 survey of Port Adelaide residents were compared with data from the 1995 National Health Survey and the 1995 South Australian Health Omnibus Survey. These data were then compared across three geographic areas in Port Adelaide, one being highly industrialised. Their relation to tobacco smoke and the presence of unflued gas appliances were examined. Finally, outdoor gaseous air pollutants were examined across the three areas. RESULTS: Males in Port Adelaide had higher rates of asthma and bronchitis/emphysema than nationally. Asthma was significantly higher for children aged 5-14 years and for adults aged 25-44 years. Bronchitis/emphysema was significantly higher for males aged 25-64. The highly industrial area had a higher rate of asthma (OR 1.85, 95% CI 1.07-3.22) in males that appeared unrelated to smoking or ambient gaseous pollutants. Smoking in Port Adelaide was significantly higher than in the general population, and was significantly associated with wheeze, night cough and bronchitis/emphysema. The presence of unflued gas heaters at home was significantly associated with asthma prevalence in males (OR 3.27, 95% CI 1.40-7.64). CONCLUSIONS: Respiratory disease appeared to be independently related to an area of high industry, smoking and presence of unflued gas appliances in Port Adelaide.

RESUMO

BACKGROUND: Few studies have assessed the validity or reliability of drinking water intake estimations. In studies investigating potential waterborne disease, this is very important. METHODS: We carried out a validity and reliability study to evaluate water intake estimations. The validity part of the study compared a telephone questionnaire to a diary. The reliability part of the study compared two telephone questionnaires. RESULTS: 253 participants were recruited. The most commonly consumed water intake categories were plain and boiled tap water. For persons aged less than 12 years, the median volume of plain water consumption was 2.9 glasses/day according to the diary. For persons aged 12 years and over, the median volume of plain water consumption was 3.0 glasses/day and for boiled water 3.0 glasses/day according to the diary. There was negligible systematic over or under reporting by participants for the telephone questionnaire in comparison to the diary and for the comparison of both telephone questionnaires. Water intake estimates were converted to categorical variables and the per cent agreement and weighted kappa statistics were calculated. For both the validity and reliability parts of the study the per cent agreement was 57-78% and the weighted kappa was 0.57-0.81. CONCLUSION: Water intake estimates show only moderate levels of validity and reliability when using a telephone questionnaire in comparison to a diary. IMPLICATIONS: Investigators of potential waterborne disease or nutritional research should exercise some caution in drawing conclusions from minor differences in drinking water intake that are obtained from a telephone questionnaire.

RESUMO

The aim of this study was to investigate effects on health of exposure to cyanobacteria as a result of recreational water activities. Participants, who were aged six years and over, were interviewed at water recreation sites in South Australia, New South Wales and Victoria on selected Sundays during January and February 1995. Telephone follow-up was conducted two and seven days later to record any subsequent diarrhoea, vomiting, flu-like symptoms, skin rashes, mouth ulcers, fevers and eye or ear irritations. On the Sundays of interview, water samples from the sites were collected for cyanobacterial cell counts and toxin analysis. There were 852 participants, of whom 75 did not have water contact on the day of interview and were considered unexposed. The 777 who had water contact were considered exposed. No significant differences in overall symptoms were found between the unexposed and exposed after two days. At seven days, there was a significant trend to increasing symptom occurrence with duration of exposure (P = 0.03). There was a significant trend to increasing symptom occurrence with increase in cell count (P = 0.04). Participants exposed to more than 5000 cells per mL for more than one hour had a significantly higher symptom occurrence rate than the unexposed. Symptoms were not correlated with the presence of hepatotoxins. These results suggest symptom occurrence was associated with duration of contact with water containing cyanobacteria, and with cyanobacterial cell density. The findings suggest that the current safety threshold for exposure of 20,000 cells per mL may be too high.

RESUMO

Pro-apoptotic molecules are generated during sepsis which may be responsible for alteration of organ function in sepsis. Removal of systemic apoptotic activity may affect recovery from sepsis. Current high flux membranes might not be sufficiently permeable to eliminate pro-apoptotic factors. We evaluated the elimination of pro-apoptotic factors induced by LPS in human whole blood by a super-permeable cellulose triacetate membrane (SUREFLUX FH 150, Nipro, Osaka, Japan) in comparison to a standard high flux cellulose triacetate membrane (UT 700, Nipro, Osaka, Japan) and a polyethersulfone plasmafilter (Bellco, Mirandola Italy) in an in vitro blood circulation. We spiked human whole blood with lipopolysaccharide from Escherichia coli (Serotype 026-86, 10 mg/ml), incubated it for 3 hours to allow cytokine generation and recirculated it at 300 ml/min for 3 hours. The UF line was first returned to the blood module at 10 min. After this, the UF was drained from 10 to 60 min at a rate of 1000 ml/h. Zero balance was obtained by re-infusion of bicarbonate buffered hemofiltration fluid. Apoptosis was assessed on U937 monocytes (incubated with plasma or ultrafiltrate) by fluorescence microscopy dyes (Hoechst 33342, propidium iodide) and annexin V flow cytometry. Caspase-3 and Caspase-8 activity was assessed on the recirculated blood monocytes by spectrophotometric methods. IL-2, IL-10 and TNFalpha were determined by commercially available ELISAs. Sieving coefficients and clearances were determined for the different cytokines. Caspase-3 and Caspase-8 were activated by LPS and remained either stable or increased during in vitro circulation. Apoptosis activity of U937 cells, when incubated with the ultrafiltrate, increased in parallel with arterial plasma values (for Uf: UT700 = 23.1%; Sureflux FH150 = 42.5%). However, by 60 min the apoptotic activity recorded with the ultrafiltrate was reduced to the levels of arterial plasma (for Uf: UT700 = 19.8%; Sureflux FH150 = 11.2%). Sieving coefficients in the super-permeable membrane were significantly higher for all measured cytokines in comparison to the standard high flux membrane (e.g. TNFalpha 0.72 vs 0.03 p < 0.001) and close to the values observed for the plasmafiltration membrane. Nevertheless protein losses measured by albumin leakage were much lower with the Sureflux filter in comparison to the plasmafilter. In conclusion, pro-apoptotic factors can be eliminated by dialytic membranes with the removal rate maximized by using super high flux dialysers which may represent a compromise between hemofiltration and plasmafiltration membranes.

RESUMO

A "Community Control Programme of Hypertension" has been implemented in a Northern Italian population as part of an international co-operative pilot project promoted by World Health Organization. The programme was planned to last five years. Three years after the start we performed what we called a "capillary" screening in the community involved in the project. In fact a team of physicians and medical students moved about in the villages of the area where extemporary ambulances were set up with the aim of identifying new hypertensives, evaluating the state of the control of hypertension as compared with the situation at the outset of the study and, more generally, as a means of strengthening the ties between the project organization and the community. In doing so we also evaluated the feasibility of an alternative approach, based upon the cooperation with an organization outside the health service system, namely the Catholic Church, to achieve the set aims in a very religious population as ours. The parish priests of the villages did eagerly cooperate with our work both in the form of propaganda and in making available the parish buildings in which the ambulances were set up. We examined 1306 subjects (47.3% males), of whom 39.5% were hypertensives ("casual" blood pressure at or above 160 or 95 or treated). Of all the hypertensives, 28.6% were new hypertensives ("unaware"), 45.3% were being treated and 13.7% had a blood pressure lower than 160/95 mmHg while under treatment "effectively treated"); 16%, though, had blood pressure values at or above 200 or 120 mmHg. The state of control of hypertension was better in women and with increasing age. As compared with the findings at the outset of the study, 27,6% more "aware", 23.9% more treated and 9.6% more "effectively treated" hypertensives were found. Using the support of an alternative (non-medical) organization in a programme of preventive medicine in the community has proved to be, in our experience, a feasible, valuable and very cheap approach.

RESUMO

BACKGROUND: When considering large areas, population-based data on coronary events are generally lacking, and such is the case for the national level. While mortality data are currently and exhaustively collected, data regarding the incidence and prevalence are often available only for subgroups of the population. METHODS: The incidence and prevalence of coronary events were estimated using a mathematical method on the basis of official mortality and population data from national statistics and survival data on coronary events from the Area Friuli of the MONICA Project, and forecasted for northern, central and southern Italy. RESULTS: The incidence is described from 1970 to 1994 and projected to the year 2004; prevalence is reported at the years 1990 and 2000. The coronary event incidence has been decreasing since 1977 among men and since 1974, 4 years before the observed mortality decline, among women. The prevalence has continued to increase as a result of three main factors: increasing survival, population aging, and incidence trend. CONCLUSIONS: Incidence and prevalence data distributed for northern, central and southern Italy are essential to plan and implement major projects aimed at improving medical care services and to evaluate the impact of public health interventions and of spontaneously changing habits among the population.

RESUMO

EUROASPIRE study has been carried out in 9 European countries with the aim of assessing coronary risk factors in high-risk patients admitted to hospital to undergo coronary revascularization procedures (coronary angioplasty or coronary artery bypass grafting) or because of angina or myocardial infarction. The results of the initial stage of the study in Italy, investigating the data from 691 hospital medical records, showed that management of risk factors in these patients was inferior than expected. In particular, the prevalence of hyperlipidaemia (63%), hypertension (40%) and diabetes (27%) was remarkably high. These results suggest that there is still a need for secondary prevention of coronary heart disease.

RESUMO

BACKGROUND: During menopause, women are more exposed to cardiovascular risk factors, some of them can be easily modified by primary and secondary prevention. This paper describes some demographic indicators and cardiovascular risk factors among Italian women. METHODS: This study describes the Italian women's cardiovascular risk, using the data collected and updated at the end of the 1990s, within the Cardiovascular Epidemiological Observatory, an Italian Collaborative Project of the Istituto Superiore di Sanità and the Italian Association of Cardiologists. RESULTS: Women aged 60 years and over represent 13% of the population; regional differences on mean values of cardiovascular risk factors are evident. Hypertension, hypercholesterolemia, diabetes and obesity are prevalent particularly in Southern Italy and among the social classes in the lowest education level. CONCLUSIONS: The data confirm the importance of the main objectives stated by the National Health Plan 1998-2000: promotion of healthier dietary habits, of physical activity, and reduction of smoking habits. This requires specific action to improve women's health condition, to provide for their special needs and to create awareness among women about the importance of preventive action also during the aging process.

RESUMO

BACKGROUND: Cardiovascular diseases are more frequent among the poorer social classes of the population. Studies including social and economic factors offer useful information when planning the strategy required in primary prevention. The aim of this investigation was to evaluate the association between socio-economic levels and cardiovascular risk factors in 3198 women and 3218 men aged 35-74 years enrolled for a cross sectional study within the Cardiovascular Epidemiologic Observatory, carried out in 1998 to evaluate the distribution of risk factors and the prevalence of cardiovascular risk conditions. METHODS: The level of education was used to determine the socio-economic status; the distribution of the risk factors and the prevalence of risk conditions were analyzed for the different levels of education. Models of logistic regression were used to evaluate the relation between the socio-economic status and obesity, cigarette smoking, hypertension, and hypercholesterolemia. RESULTS: A higher level of education is significantly protective against both obesity and cigarette smoking. With regard to obesity among males compared to those with a university degree the odds ratio increased to 1.6 for those with an upper secondary education diploma (95% confidence interval--CI 1.09-2.51) and to 3.5 for those without any qualification (95% CI 1.97-6.21). Among women the odds ratio increased to 3.2 (95% CI 1.81-5.81) and to 4.8 (95% CI 2.55-8.98) for the same levels of education. With regard to smoking among males compared to those with a university degree the odds ratio increased to 1.4 for those holding an upper secondary education diploma (95% CI 1.07-1.94) and to 2.3 for those without any qualification (95% CI 1.40-3.68). For men living in central or southern Italy, the odds ratio for cigarette smoking increased to 1.3 (95% CI 1.06-1.57) and to 1.5 (95% CI 1.24-1.82) and the odds ratio for hypercholesterolemia decreased to 0.8 (95% CI 0.62-0.95) and to 0.7 (95% CI 0.58-0.89); with regard to women, living in the same geographic areas the odds ratio for obesity increased to 1.3 (95% CI 1.03-1.65) and to 2.3 (95% CI 1.81-2.83). CONCLUSIONS: In primary prevention it is important to focus the attention on obesity and on smoking habits among the poorer social classes.
