Сравнение анамнестических характеристик, особенностей образа жизни и сопутствующих заболеваний у пациентов с ожирением при наличии и отсутствии сахарного диабета 2 типа

Abstract

Background : Obesity is one of the most significant risk factors for type 2 diabetes (T2D), but a large number of patients with morbid obesity maintain normal glycemia for a long time. There are no definite easy-to-measure clinical features that distinguish severely obese people who will or will not develop T2D. These features may be useful in clinical practice to predict T2D development in obese patients. Aims: We aimed to identify clinical features (lifestyle factors, obesity history, concomitant diseases) that may be associated with T2D in obese patients. Materials and methods : The study was conducted at single center during 2002 and 2017 and recruited patients with BMI≥30 kg/m2 who attended bariatric surgeon. Patients weight and height were assessed by the doctor, other features were obtained from the questionnaire: overweight and obesity history (age of onset, duration, family history of obesity), lifestyle factors, T2D and concomitant diseases medical history. Patients were divided into 2 groups with regard to the presence of T2D. Data analysis was performed with Statistica 13.3. Results : The study included 170 patients with known T2D and 528 patients without history of T2D and prediabetes. Both groups had similar gender structure, as well as current and peak BMI. There were no significant differences in overweight/obesity duration, obesity family history, lifestyle factors and smoking status of patients. Obese patients without T2D were younger than T2D patients at the time of T2D onset (median age 40 and 45 years respectively). Patients without T2D started to gain weight earlier than those with T2D (median age 17 and 25 years respectively) and reached their peak BMI during 1 year before study entry, while patients with T2D went through maximum weight previously. The frequencies of concomitant diseases didn’t differ between the groups with the exception of hypertension that started later in patients with T2D (median age 51 and 47 years in patients with and without T2D respectively); also patients with T2D had gastroesophageal reflux disease (GERD) and chronic back pain less often than patients without T2D with regard to age. Conclusions : Clinical features that distinguished obese patients with and without T2D were age at the start of overweight/ obesity and concomitant disease profile (hypertension, GERD, chronic back pain) at corresponding age.
