Epidemiology of cardiovascular risk factors in Greece: aims, design and baseline characteristics of the ATTICA study

BACKGROUND: In an attempt to evaluate the levels of several cardiovascular risk factors in Greece we conducted a population-based health and nutrition survey, the "ATTICA study". In this work we present the design and the methodology of the study, as well as the status of various baseline characteristics of the participants. METHODS: From May 2001 to December 2002 we randomly enrolled 1514 adult men and 1528 adult women, stratified by age – gender (census 2000), from the greater area of Athens. More than 300 demographic, lifestyle, behavioral, dietary, clinical and biochemical variables have been recorded. RESULTS: Regarding the frequency of the classical cardiovascular risk factors we observed that 51% of men and 39% of women reported smokers (p < 0.05), 37% of men and 25% of women were defined as hypertensives (p < 0.05), 46% of men and 40% of women had total serum cholesterol levels above 200 mg/dl (p < 0.05) and 8% of men and 6% of women had history of diabetes mellitus. Moreover, 20% of men and 15% of women were obese (p < 0.05), while men were more physically active as compared to women (42% vs. 39%, p < 0.05). 19% of men and 38% of women had mild to severe depressive symptoms (p < 0.01). Finally, 72 men (5%) and 45 (3%) women reported history of coronary heart disease at entry evaluation. CONCLUSIONS: The prevalence of the common cardiovascular risk factors in our population seems high. As a consequence a considerable proportion of Greek adults are at "high-risk" for future cardiovascular events

Epidemiology of acute coronary syndromes in a Mediterranean country; aims, design and baseline characteristics of the Greek study of acute coronary syndromes (GREECS)

BACKGROUND: The present study GREECS was conducted in order to evaluate the annual incidence of acute coronary syndromes (ACS) and to delineate the role of clinical, biochemical, lifestyle and behavioral characteristics on the severity of disease. In this work we present the design, methodology of the study and various baseline characteristics of people with ACS. METHODS/DESIGN: A sample of 6 hospitals located in Greek urban and rural regions was selected. In these hospitals we recorded almost all admissions due to ACS, from October 2003 to September 2004. Socio-demographic, clinical, dietary, psychological and other lifestyle characteristics were recorded. 2172 patients were included in the study (76% were men and 24% women). The crude annual incidence rate was 22.6 per 10,000 people and the highest frequency of events was observed in winter. The in-hospital mortality rate was 4.3%. The most common discharged diagnosis for men was Q-wave MI, while for women it was unstable angina. DISCUSSION: This study aims to demonstrate current information about the epidemiology of patients who suffer from ACS, in Greece

Second-hand smoke and chronic bronchitis in Taiwanese women: a health-care based study

<p>Abstract</p> <p>Background</p> <p>Cigarette smoking cannot fully explain the epidemiologic characteristics of chronic obstructive pulmonary disease (COPD) in women, particularly for those who rarely smoke, but COPD risk is not less than men. The aim of our study is to investigate the relationship between second-hand smoke (SHS) exposure and chronic bronchitis in Taiwanese women.</p> <p>Methods</p> <p>We used Taiwan's National Health Insurance Bureau claims data in 1999, and cross-checked using criteria set by the American Thoracic Society; there were 33 women with chronic bronchitis, 182 with probable chronic bronchitis, and 205 with no chronic bronchitis during our interview time between 2000 and 2005. We measured second-hand smoke (SHS) exposure by self-reported measures (household users and duration of exposure), and validated this by measuring urinary cotinine levels of a subset subjects. Classification of chronic bronchitis was also based on spirometry defined according to the GOLD guidelines to get the severity of COPD.</p> <p>Results</p> <p>Women who smoked and women who had been exposed to a lifetime of SHS were 24.81-fold (95% CI: 5.78-106.38) and 3.65-fold (95% CI: 1.19-11.26) more likely to have chronic bronchitis, respectively, than those who had not been exposed to SHS. In addition, there was a significant increasing trend between the severity of COPD and exposure years of SHS (<it>p </it>< 0.01). The population attributable risk percentages of chronic bronchitis for smokers and those exposed to SHS were 23.2 and 47.3% respectively.</p> <p>Conclusions</p> <p>These findings indicate that, besides cigarette smoking, exposure to SHS is a major risk factor for chronic bronchitis in Taiwanese women.</p

Isolation of Salmonellae from Sewage with a New Procedure of Enrichment

Forty samples of sewage on Moore&apos;s swabs were examined for the presence of salmonellae. They were first pre‐enriched in buffered peptone water. From each pre‐enrichment, three enrichments were made: (1) in a new, considerably modified, formula of Rappaport medium (R 10) incubated at 43 °C (R 10/43 °C), (2) in the usual formula (R25) of the same medium at 37 °C (R25/37 °C) and (3) in Muller‐Kauffmann&apos;s tetrathionate broth at 43 °C (MK/43 °C). Practically the same numbers of swabs were found positive by the first two enrichment procedures, 38 and 39 respectively, while only 17 were found positive by the MK procedure. The R10/43 °C method was superior to the two other procedures; it yielded 103 strains of salmonellae as against 82 with the second Rappaport procedure, and only 25 with the MK/43 °C technique. A similar observation was made concerning the frequency of isolation of different serotypes by the three procedures; the number of the isolated serotypes was 24, 19 and 11, respectively. The new R 10/43 °C method of enrichment had also a much stronger inhibitory effect on the competing bacteria than the two other procedures of enrichment used. Copyright © 1978, Wiley Blackwell.
