[Group preventive consulting influence on body mass correction and nutrition disorders. 5-year prospective survey]

The aim of the work was to analyze education technologies efficacy using group methods of prevention (body mass correction school) in patients with overweight and obesity, living in Extreme North, according to a 5-year prospective survey. 181 Extreme North alien inhabitants have been investigated (23.2% men, 76.8% women) with overweight and obesity. 144 of them were surveyed during 5 years. Age median was 37 (29-49) years, including men - 33 (29-43) and women - 39.5 (27.5-48) (p=0.123). All participants were divided into 2 groups depending on preventive group education compliance. Group 1 received brief recommendations for the inspection, Group 2 was trained with the group of preventive counseling. Within 3 months of surveillance target body mass reduction was achieved by 11.3% of patients of the group 1 and 31.5% of patients of the group 2 (p=0.0018). By the end of the first year these parameters proved to be 7% and 16.4% (p=0.0453). After that there was no significant difference between groups, although about 5-6% of responders kept the achieved target of BM reduction even in group 1. Group prevention consulting is associated with short time reduction of such risk factors prevalence as low physical activity (from 86.3 to 61.1% during 3 months, p<0.005), insufficient fruits and vegetables consumption and violation of macro- and micronutrient composition of the daily diet. It is also accompanied with lower cumulative proportion of patients without all metabolic syndrome components (Cox's F-Test: F=2.61; p=0.0178) and a significant reduction of percent of patients having SCORE-risk >5% (p=0.0461) after 5 years of surveillance. Thus, group preventive consulting raises awareness of patients about their health status, leads to daily meal ratio impairment reduction, decreases prevalence of obesity and low physical activity in short time period and reduces MS - risk. During 3 months after consulting body mass reduction (of 5% or more) was observed in 30% of patients. Achieved result is stable within following 12 months in less than 16% of patients. In the longer term, education is accompanied by a decrease in MS risk and some reduction in SCORE-risk.
