Type 2 diabetes mellitus is associated with obesity, smoking and low socioeconomic status in large and representative samples of rural, urban, and suburban adult Greek populations.

OBJECTIVE: In this cross-sectional epidemiologic study we examined the association between type 2 diabetes mellitus and demographic, clinical, and socioeconomic parameters in large rural, urban and suburban populations of adult Greeks. DESIGN: Of the total target adult population (≥19 years, n=14233) in nine selected geographical regions covering rural, suburban, and urban areas of Greece, 10,647 subjects were included in the study. Data were collected by physicians who interviewed subjects at their homes between 1996 and 1999. RESULTS: A total of 8740 subjects participated (response rate 82.1%). Among participants there were 360 subjects with type 2 diabetes. Multivariate logistic regression analysis after adjustment for factors associated with type 2 DM in univariate analyses including occupation, education level, place of residence, and number of persons living together demonstrated that advancing age, obesity-but not overweight status-and smoking in the past were associated with higher odds of type 2 diabetes. Moreover, low socioeconomic status was associated with type 2 diabetes independently of the effects of age, obesity, and smoking. CONCLUSIONS: In large representative rural, urban, and suburban populations of adult Greeks, type 2 Diabetes was associated with advancing age, obesity, exposure to smoke, and low socioeconomic status.

Prevalence of rheumatic diseases in Greece: a cross-sectional population based epidemiological study. The ESORDIG Study.

OBJECTIVE: To assess the prevalence of rheumatic diseases in Greek urban, suburban, and rural adult general populations. METHODS: This cross-sectional population based epidemiological study of rheumatic diseases in Greece (the ESORDIG Study) was conducted on the total adult population of 2 urban, one suburban, and 4 rural communities (8547 subjects), as well as on 2100 out of 5686 randomly selected subjects in one suburban and one rural community. The study, based on a standardized questionnaire and clinical evaluation and laboratory investigation when necessary, was carried out by rheumatologists who visited the target population at their homes. Either established classification criteria or criteria set for the purposes of the study were used for diagnosis. RESULTS: A total of 8740 subjects participated in the study (response rate 82.1%). The overall age and sex adjusted prevalence (prevalence(asa)) of rheumatic diseases in the total target adult population was 26.9% (95% CI 26.2-27.6), being significantly higher among women (33.7%) than men (19.9%) (p < 0.0005). Disease prevalence(asa) increased significantly with age (p < 0.0005). The most common disease group was low back pain, with a prevalence(asa) of 11.0%, followed by symptomatic peripheral osteoarthritis (7.9%), neck pain (4.8%), miscellaneous rheumatic disorders (4.4%), soft tissue rheumatism disorders (4.3%), and inflammatory rheumatic disease (2.1%). Logistic regression analysis showed a significant positive association of female or male sex, age >or= 50 years, high body mass index, low level of education, moderate or heavy alcohol consumption, and high socioeconomic level with particular diseases or disease groups. CONCLUSION: These findings indicate rheumatic diseases are very common in the general adult population of Greece; 26.9% of adults currently have active or chronic rheumatic disease in remission.
