Sažetak
Introduction: Overweight and obesity present major challenges for the public healthcare system. Number of persons with diagnosed obesity is continuously increasing, which is concerning because obesity is a significant risk factor for cardiovascular disorders. It has been shown that educational interventions may be effective for obesity, but there are various component that may be included in such interventions and thus contribute to their comparative effectiveness. Participants and methods: We tested the effect of education as an intervention for adults with obesity in a non-controlled clinical study. The education consisted of an individual nutrition plan based on nutrition habits estimated by the Food frequency questionnaire (FFQ) and the 24h dietary recall interview method together with anthropometric analysis which included measuring body mass (BM), height, body mass index (BMI), %fat, %muscle tissue, visceral fat and the basal metabolic rate (BMR). All the participants had to go through the individual nutrition counselling. Body mass reduction was monitored in the period of 3 months, minimum number of visits was 3 and maximal 7. Participants were divided in subgroups according to sex and we used Mann-Whitney U test, t-test and Pearson correlation coefficient to analyse the differences. Participants were asked do they conduct some sort of physical exercise and 48.8% of men and 38.3% women stated that they attend fitness centers at least two to six days in a week, their training regimen was not surveyed. Results and Debate: The study included 41 men (min BM=69 kg ; max BM=139 kg ; min BMI=22.2 ; max BMI=42.1) and 180 women (min BM=57 kg ; max BM=134 kg ; min BMI=20.8 ; max BMI=50.2). After 3 months from baseline, average body mass decreased 6.86% in women and 7.1% in men. There were 92% of participants whose body mass was lower after 3 months (range of body mass decrease in men was 2-18.2% and in women 0- 21.3%). The results indicated positive correlation (p=0.48) between number of counselling sessions attended in all participants (p<0.05) meaning that the higher rate of attendance lead to the higher loss of body mass. However, the same association was not found in subgroups based on sex (women p=0.43 ; men p= 0.58). At the beginning of the study adipose tissue (AT) and muscle tissue (MT) percentage was measured (men AT 31.49%, MT 32.43%), (women AT 44.15%, MT 24.72%) so as at the end of the study (men AT 28.21%, MT 34.37%), (woman AT 41.01%, MT 26.24%) and body composition change was in men AT -2.2%, MT +1.26% and in woman AT -3.23%, MT +1.53%. Conclusion: In conclusion, our study provided evidence that an educational intervention consisting of individual nutrition plan and counselling sessions can lead to decrease of body mass in adults with obesity. Our study indicates that education provided by a nutritionists may play a significant role in body mass regulation since the study noted higher rate of success in weight loss among patients with repeated occurrence of nutrition counselling sessions.
