Sense of coherence in people with and without type 2 diabetes mellitus: an observational study from Greece.

Abstract

Background Antonovsky's concept of sense of coherence (SOC) has been suggested to relate to health, especially mental health and preventive health behaviours. Psychological distress has been identified as a risk factor for pre-diabetes and type 2 diabetes mellitus. The study of SOC and diabetes has not received much attention in Greece. This study aims to explore the extent to which type 2 diabetes mellitus can affect the SOC score. Methods An observational design was used to test the study hypothesis that individuals with type 2 diabetes mellitus would have a lower SOC than those without diabetes mellitus. A total of 202 individuals were studied, consisting of 100 people with diabetes mellitus (the study group) and 102 people with non-chronic orthopaedic conditions (the control group). All of the participants were patients of the Diabetic Clinic or the Orthopaedic Clinic of Livadia Hospital in Central Greece. SOC was assessed using a 29-item SOC questionnaire that had been translated into Greek and validated. Results Patients without type 2 diabetes mellitus had 2.4 times higher odds of having a high SOC score than patients with type 2 diabetes mellitus (P = 0.036; odds ratio [OR] = 2.35, 95% confidence interval [CI] = 1.06-5.23). Male patients had 3.9 times higher odds of having a high SOC score (P < 0.001; OR = 3.85, 95% CI = 1.71-8.67) than female patients. With regard to education, patients with a lower level of education had almost three times higher odds of having a high SOC score than patients with a higher level of education (P = 0.024; OR = 2.97, 95% CI = 1.15-7.67). Conclusions This study adds to the existing literature and indicates that SOC is a health asset. A study with an experimental design would clarify the interesting hypothesis of this study.
