Introduction/Objective. Diabetes mellitus and its chronic complications
impair quality of life when compared to the one of the general population.
The objective of this study was to determine the prevalence of > 14
unhealthy days per month among the patients with diabetes in Serbia and to
determine the association of the socio-demographic characteristics and
health characteristics with the total of > 14 unhealthy days. Methods.
Serbian version of a generic self-administered questionnaire from Centers
for Disease Control and Prevention (CDC-HRQOL-4) was used for data
collection in all three levels of care. Results. The study involved 4898
patients with diabetes, 2283 (46.6%) men and 2611 (53.4%) women. Overall
mean age was 57.3 ? 12.2 years with over one fifth (23.2 %) were younger
than 50 years. Multivariate logistic regression analyses indicated that age
> 65 (OR:1.575, 95%CI 1.100-2.256), being a woman (OR: 1.287, 95% CI
1.042-1.588), lower education (OR: 1.383, 95%CI 1.091-1.754), felt depressed
? 14 days (OR: 3.689, 95% CI 2.221-6.128), felt anxious ? 14 days (OR:
1.749, 95% CI 1.113-2.749), poor sleep ? 14 days (OR:2.161, 95%CI
1.569-2.988), fair or poor self-rated health ? 14 days (OR: 4.322, 95%CI
3.474-5.376) were associated with unhealthy days ? 14 days. The strongest
negative association was observed between limited physical activity ? 14
days and a decrease in the quality of life of people with diabetes (OR:
22.176, 95%CI 10.971-44.824). Conclusion. This study highlights association
between impaired quality of life in patients with diabetes and physical
activity limitations. Limited physical activity is the factor with the
greatest negative impact on the quality of life particularly in older, less
educated women with diabetes.
