[Effectiveness of a protocol treatment for overweight/obese patients (SIAN - ASL RMA)].

To evaluate the efficacy of treatment protocols in patients overweight/obese, pertaining to outpatient of dietary preventive of SIAN (in English: Service of Food Hygiene and Nutrition) RMA.We extracted data from the medical records of patients with BMI≥25 (2009-2012). It was conducted a descriptive analysis, univariate analysis (chi-square test; p≤0.05) and multivariate logistic regression analysis considering as "weight loss" the outcome measure.There were 762 records (76.2% female; mean age 52 years). BMI average of beginning treatment: 30.26; BMI of the end of treatment: 28.37; minimum maximum range of variation of weight after treatment: -28.9 Kg and +6.5 Kg. The 55.2% of the sample has lost up to 4.9 kg, 32.4% from 5.0 to 9.9 kg, 8.1% from 10.0 to 19.9 Kg, 0.9% from 20 to 28.9 Kg. The higher initial BMI and the longer treatment, have a lower likelihood of weight loss (B=-1.267, p<0.001; B =-0.408, p<0.001); females and those who have an older age are more likely to lose weight (B=0.030, p<0.003; B=1.260, p<0.001).The current study highlight the efficacy of treatment protocols in overweight/obese patients. The population that benefits from the treatment more rigidly set on the estimated caloric needs is the one that starts from lower BMI and who therefore need less time to reach a certain weight loss. Instead, those who started from higher BMI is a population supposedly "binger", more resistant to the single dietary treatment and, as recognized by the scientific community, it requires a multidisciplinary approach.
