AIM. To investigate illness perception in patients with type 2 diabetes mellitus and its association with the degree of control over relevant cardiovascular risk factors. METHODS. A cross-sectional questionnaire-based study was performed from June 2007 to March 2008. A stratified random sample of 46 Croatian general practitioners was asked to select, using systematic sampling, the first 6 patients with type 2 diabetes mellitus aged > or =18 years who visited them for consultation during the study period. Data on 250 patients included patient illness perception assessment (Brief Illness Perception Questionnaire, IPQ), cardiovascular risk factors, and socio-demographic data. RESULTS. The patients' mean age was 63.0+/-10.9 years and mean duration of diabetes was 9.3+/-7.8 years. The patients' illness perception assessment on an 11-point (0 to 10) scale showed the highest median scores (interquartile range): 10 (8 to 10) for "timeline" and 8 (7 to 9) for "treatment control," followed by 7 (5 to 8) for "personal control," 7 (5 to 9) for "understanding," 5 (3 to 7) for "consequences," 6 (4 to 7) for "concern," and 5 (2 to 7) for "emotional response." The lowest score was 3 (1 to 5) for "identity." Multivariate logistic regression showed that the Brief IPQ item "concern" (P<0.001) was a significant predictor of body mass index; "personal control" (P<0.001) and "concern" (P=0.048) were significant predictors of fasting blood glucose; "treatment control" (P=0.009) was a significant predictor of total cholesterol; and "understanding" (P=0.010) was a significant predictor of blood pressure. CONCLUSION. As patients' beliefs seem to be associated with the degree of control over cardiovascular risk factors, they should be included in routine clinical assessments.

Our data suggest that firefighters are at risk for developing acute and chronic respiratory symptoms as well as obstructive airway changes.

In this cross-sectional study, the prevalence of acute and chronic respiratory symptoms and lung function were investigated in 236 (169 male and 67 female) livestock farmworkers raising domestic animals, including cattle and horses. The prevalence of acute and chronic respiratory symptoms was recorded by administering a modified version of the British Medical Research Council questionnaire on respiratory symptoms. Lung function was measured by recording the maximum expiratory flow-volume curves from which the forced vital capacity, the one-second forced expiratory volume, and the maximum expiratory flow rates at 50% and the last 25% were measured. There was a significantly higher prevalence of almost all chronic respiratory symptoms in farmers compared with controls: highest among men for chronic cough (27.2%) and highest among women for dyspnea (28.3%). Typical symptoms of occupational asthma were diagnosed in 3.6% of the male and 1.5% of the female livestock farmers. A logistic regression analysis performed on chronic respiratory symptoms of livestock workers indicate significant effects of smoking (P < 0.001) on all symptoms except occupational asthma. A large number of male and female livestock farmworkers complained of acute work-related symptoms: highest for dry cough (52.2%) and shortness of breath (44.9%). Lung function data among these workers demonstrated a trend toward lower lung function in general. Multivariate analysis of lung function parameters indicate significant effects of length of employment and smoking in male and length of employment in female livestock farmworkers. The data suggest that employment in livestock farming may be associated in a dose-dependent manner with the development of acute and chronic respiratory symptoms and lung function changes.
