The study is based on the results of measurement of height, mass and body mass index in 1783 residents of a large industrial center – 45 years and older patients of polyclinics, with and without endocrine pathology. There was revealed the incidence of normal weight, overweight and obesity. It was revealed that 40% of the patients were suffering from obesity of various degree, 38% were overweight. It was proved that the patients with diagnosed chronic endocrine disorders were 1.2 times more likely to have obesity, and 1.1 times less likely to be overweight if they had no endocrine system pathologies. The greatest incidence of overweight patients was registered in men over 70 with chronic endocrine disorders, and in women of 60-69; the greatest incidence of obese patients was registered in women over 60. It was shown that more than 60% of obese patients, visitors to clinics, are not monitored by endocrinologists, which indicates the need to improve health care provided to clinics visitors, including endocrine patients with the presence of excess body weight.
