Prevalence of diabetes and cardiovascular risk factors of industrial area in southern Poland

Can Periodical Examinations of Employees Be Useful in Detection of Glycaemia Impairment and Improving Patients' Adherence to Medical Recommendations?

Worldwide epidemiological data indicates insufficient diagnosis of diabetes as an increasing public health problem. In the search for solutions to this disadvantageous situation, occupational medicine health services seem to open up a unique opportunity to recognize some abnormalities in the early stages, especially among the asymptomatic working-age population. 316 workers underwent obligatory prophylactic examinations. In patients with twice assayed FGL ≥ 126 mg/dL (7.0 mmol/L) an additional intervention was implemented, including further diagnostic processes and therapy in General Practice (GP), followed by examination by an occupational health specialist within 3 months. The diagnosis of previously unknown diabetes was established among 2.5% of examined workers. All patients referred to the GP due to detected glycaemia impairment visited their doctor and finished the diagnostic process, took up therapy constrained by the occupational health physician to show the effects of intervention within 3 months. Prophylactic medical check-ups allow improved compliance and medical surveillance over glycaemia impairment in patients with prediabetes states, unknown diabetes or uncontrolled clinical course of diabetes. Considering fasting glucose level during mandatory prophylactic examination helps effective prevention of diabetes and its complications and thus provides public health system benefits.

Residents' Self-Reported Health Effects and Annoyance in Relation to Air Pollution Exposure in an Industrial Area in Eastern-Estonia

Eastern Estonia has large oil shale mines and industrial facilities mainly focused on electricity generation from oil shale and shale oil extraction, which produce high air pollution emissions. The "Study of the health impact of the oil shale sector-SOHOS" was aimed at identifying the impacts on residents' health and annoyance due to the industrial processing. First, a population-wide survey about health effects and annoyance was carried out. Second, the total and oil shale sectors' emitted concentrations of benzene, phenol, and PM2.5 were modelled. Third, the differences between groups were tested and relationships between health effects and environmental pollution studied using multiple regression analysis. Compared to the control groups from non-industrial areas in Tartu or Lääne-Viru, residents of Ida-Viru more frequently (p < 0.05) reported wheezing, chest tightness, shortness of breath, asthma attacks, a long-term cough, hypertension, heart diseases, myocardial infarction, stroke, and diabetes. All health effects except asthma were reported more frequently among non-Estonians. People living in regions with higher levels of PM2.5, had significantly higher odds (p < 0.05) of experiencing chest tightness (OR = 1.13, 95% CI 1.02-1.26), shortness of breath (1.16, 1.03-1.31) or an asthma attack (1.22, 1.04-1.42) during the previous year. People living in regions with higher levels of benzene had higher odds of experiencing myocardial infarction (1.98, 1.11-3.53) and with higher levels of phenol chest tightness (1.44, 1.03-2.00), long-term cough (1.48, 1.06-2.07) and myocardial infarction (2.17, 1.23-3.83). The prevalence of adverse health effects was also higher among those who had been working in the oil shale sector. Next to direct health effects, up to a quarter of the residents of Ida-Viru County were highly annoyed about air pollution. Perceived health risk from air pollution increased the odds of being annoyed. Annoyed people in Ida-Viru had significantly higher odds of experiencing respiratory symptoms during the last 12 months, e.g., wheezing (2.30, 1.31-4.04), chest tightness (2.88, 1.91-4.33 or attack of coughing (1.99, 1.34-2.95).

Cost of severe hypoglycaemia in nine European countries

OBJECTIVE

Complications contribute largely to the economic gravity of diabetes mellitus (DM). How they arise and are treated differs substantially between countries. This paper assesses the total annual, direct, and indirect cost of severe hypoglycemia events (SHEs) in nine European countries: Bulgaria, Croatia, the Czech Republic, Greece, Hungary, Macedonia/the former Yugoslav Republic of Macedonia (MK), Poland, Slovenia, and Spain.

METHODS

Data was collected on epidemiology, treatment structure, SHE-driven resource consumption, and unit costs. Two systematic reviews-on the SHE rates and the resources used for treatment-and data on the days-of-work lost due to SHE along with salaries and employment rates were used. The total SHE cost in each country was calculated and how the differences are driven by individual parameters was analysed.

RESULTS

The annual costs of SHEs varied in absolute terms from €379,951.25 in MK up to €58,429,684.40 in Spain, or-when expressed per one drug-treated DM patient-from €5.47 in Bulgaria up to €17.74 in Spain. Indirect cost constituted between 6.01% (MK) and 26.49% (Hungary) of the total cost. The differences between countries are driven mostly by the cost of treating a single event, and this is related to general differences in prices.

LIMITATIONS

The main limitation is the lack of good quality data in some parts, and the necessity to use mean-value imputations, experts' opinions, etc. Additionally, we only considered DM treatment as the SHE driver, while other elements, e.g. style of living, may contribute substantially.

CONCLUSIONS

A common framework can be applied to estimate the economic burden of SHE in various countries, allowing one to identify the drivers of differences in cost. Treating DM is complex, and so no resolute conclusions ought to be drawn as to whether SHE management is better in one country than another.

Costs of diabetes and its complications in Poland

OBJECTIVE

Diabetes mellitus (DM) is a major health problem with severe complications and a significant impact on quality of life. It constitutes an enormous burden of disease due to high prevalence, severe co-morbidities and high costs for society. This study is the first comprehensive study on the direct and indirect costs of DM (type 1 and type 2) and associated complications in Poland.

METHODS

In order to estimate the direct medical costs of DM and its complications, including the costs of medical consultation, hospitalisation, rehabilitation, drugs and medical equipment, data from the National Health Fund were used. Indirect costs on loss of productivity due to diabetes and its complications were based on data obtained from the ZUS (Social Insurance Institution) and from GUS (Poland's Central Statistical Office). Attributable risk methodology was used to assess the burden of DM complications.

RESULTS

A continuous increase of the direct costs of diabetes has been observed since the year 2005. In the analysed time period (2005-2009) the direct costs of medical services for both types of DM doubled. DM is a cause of significant sickness absence and incapacity for work and therefore is associated with a growing productivity decline in Poland. The highest direct costs and indirect costs are associated with treatment of diabetes-related complications. Direct costs of hospital complication treatment were EUR 332 million, which exceeded by more than five times the direct costs of hospital treatment of diabetes per se, which in the same year amounted to EUR 58.5 million. The indirect costs of diabetes-related complications were higher by 41% compared with indirect costs related to DM itself. Total costs of health care services for DM and its complications amounted to EUR 654 million, which constitutes a 2.8% of total health care costs in Poland. Total DM cost in Poland in 2009 amounted EURO 1.5 billion.

CONCLUSIONS

DM is causing a growing economic burden on the health care system and on Polish society in terms of health care and productivity losses. Most of the total cost of diabetes are indirect costs caused by productivity losses. Both direct and indirect costs are driven by the cost of diabetes complications.

Diabetes mellitus in pancreatic cancer patients in the Czech Republic: sex differences

Aims. The prevalence of diabetes mellitus in pancreatic cancer patients and control subjects was compared. Methods. Retrospective evaluation of 182 pancreatic cancer patients and 135 controls. The presence of diabetes was evaluated and the time period between the diagnosis of diabetes and pancreatic cancer was assessed. A subanalysis based on patient sex was conducted. Results. Diabetes mellitus was present in 64 patients (35.2%) in pancreatic cancer group and in 27 patients (20.0%) in control group (χ² = 8.709; P = 0.003). In 18 patients (28.1% of diabetic pancreatic cancer patients) diabetes was new-onset. Diabetes was new-onset in 23.3% of females compared to 38.1% of males (χ² = 1.537; P = 0.215). The overall prevalence of diabetes was significantly higher among female pancreatic cancer patients (25% versus 43.9%; χ² = 7.070, P = 0.008), while diabetes prevalence was equally represented in the control group patients (22.1% versus 17.2%; χ² = 0.484, P = 0.487). Conclusion. The prevalence of diabetes mellitus in study group of pancreatic cancer patients was significantly higher when compared to control group. Pancreatic cancer patients with diabetes were predominantly females, while diabetes was equally prevalent among sexes in the control group. Therefore, patient sex may play important role in the risk stratification.

Prevalence rate of diabetes mellitus and impaired fasting glycemia in Hungary: cross-sectional study on nationally representative sample of people aged 20-69 years

AIM

To obtain correct evaluation of the prevalence rate of diabetes mellitus and impaired fasting glycemia (IFG) in Hungary.

METHOD

The study was performed on a nationally representative sample covered by the Hungarian General Practitioners' Morbidity Sentinel Stations Program. The source population consisted of all persons aged 20-69 years who were registered with the participating centers. The prevalence rates were adjusted to age and sex distribution of the total Hungarian population. Fasting blood samples of 1803 participants were evaluated. Response rate was 90.7%.

RESULTS

In addition to 130 (7.21%) patients with established diabetes, 26 participants with newly diagnosed diabetes were found, resulting in a total crude diabetes prevalence of 8.65% (men: 11.16%; women: 6.41%; P<0.001). After weighting for age and sex, the prevalence rate of diabetes in participants aged 20-69 years should be set at 7.47% (95% confidence interval [CI], 6.26-8.69) (men: 9.49%; 95% CI, 7.52-11.46; women: 5.58%; 95% CI, 4.12-7.04). In addition to 41 (2.27%) patients with established IFG (fasting blood glucose: 6.1-6.9 mmol/L), 47 participants with newly diagnosed IFG were found, resulting in a total crude IFG prevalence of 4.88% (men: 6.11%; women: 3.78%; P=0.022). After making corrections for weighting age and sex, the total IFG prevalence rate in participants aged 20-69 years should be set at 4.39% (95% CI, 3.44-5.34) (men: 5.52%; 95% CI, 3.99-7.06; women: 3.33%; 95% CI, 2.19-4.47).

CONCLUSION

The prevalence rate of diabetes and IFG in Hungary is higher than previously estimated by experts and authorities. The present data may serve as a base for comparative investigations in the future.
