Subjects and methods: randomized intervention study zado controlled, in which 42 adults participated with obesity. Subjects assigned to the Intensive Program Lifestyle Change received a protocol of validated behavior change “Balancing Style Life ”in 12 sessions, weekly consultations with a nutritionist logo and meal replacements. The Traditional Treatment It consisted of monthly consultations with a nutritionist who provided nutritional and physical activity guidance. Results: after three months 97% was measured of the participants who started the study. The subjects Intensive Lifestyle Change Program and the Traditional Treatment showed the following changes in body weight: (median [25-75 percentile]) (-4.7 kg [-6.5, -3.1]) vs. (+0.4 kg [-0.3, 1.3]) 62% of Intensive Change Program participants Lifestyle lost more than 5% of body weight, against 0% in the Traditional Treatment group (p <0.001). Conclusions: this study is preliminary evidence that an Intensive Style Change Program of Life can be an effective alternative for treatment Obesity in the first level of attention.

OBESITY MANAGEMENT IN THE PRIMARY CARE SETTING BY AN INTENSIVE LIFESTYLE INTERVENTION Abstract Objective: the aim of this study was to compare an In- tensive Lifestyle Intervention against Traditional Treat- ment for obesity management in the primary care setting. Subjects and methods: interventional randomized controlled study with participation of 42 obese adults. Subjects assigned to the Intensive Lifestyle Intervention received a validated behavior change protocol “Group Lifestyle Balance ”in 12 sessions, weekly consultations by a nutritionist and meal replacements. Traditional Treat- ment consisted of monthly consultations with a nutritio- nist that provided nutritional assessment and physical activity. Results: almost all study participants (97%) were me- asured after 3 months of intervention. Intensive Lifestyle Intervention and Traditional Treatment subjects showed the following changes in body weight: (Median [25-75th percentile]) (-4.7 kg [-6.5, -3.1]) vs. (+0.4 kg [-0.3, 1.3]) Sixty two percent of Intensive Lifestyle Intervention group participants lost more than 5% body weight vs. 0 % in the traditional treatment group (p <0.001). Conclusions: this preliminary evidence showed that an Intensive Lifestyle Intervention can be an effective stra- tegy for obesity management in the primary care setting.

According to the last National Health and Nutrition Survey “ENSANUT 2012 ”obesity affects 32.4% of Mexicans 1 Likewise, the prevalence of obesity in Spain affects 17% of the adult population 2 and countries like Brazil, Argentina and Chile also have high prevalence lessons in the order of 19.5% to 29.4% 3. Obesity It is one of the main risk factors for diabetes type 2 and cardiovascular diseases 4 , which in turn They are among the leading causes of death in Mexico and other Spanish-speaking countries 5 . A loss of weight moderate 5% to 10% in individuals with obesity dad, is associated with significant improvements in the levels of glucose, plasma lipids, reduction in tension arterial, among other benefits 4 Recently, The Panel of Obesity Experts of the United States “Obesity 2013”, has proposed to Intensive Lifestyle Change Programs (PI- CEV) as the gold standard for handling sity 4 . These programs consist of group visits or weekly individuals (≥ 14 sessions in 6 months), in the initial phase of treatment with a health provider trained lud, where the goal is to make changes in diet, physical activity and body weight, using a validated behavior change protocol 4.6 The Diabetes Prevention Program study and the study Actions for Health in Diabetes showed in 2 multicenter randomized clinical trials cos, that it is possible to achieve adequate weight control body, through a PICEV 7.8 . In the study of Diabetes Prevention Program, participants they managed to lose an average of 7 kg per year of treatment and kept 80% of it at 2.8 years 7 . This it resulted in a reduction in the incidence of diabetes 58% among other benefits, compared to a control group 7 . In the study Actions for Health In Diabetes, patients who received PICEV lo- they recorded a 8.7% reduction per year of follow-up and maintained a loss of 4.4% at 4 years and 4.7% at 8 years old 8 . Concomitant to weight reduction, the patients showed improvements in risk factors diovascular 9 , remission of diabetes 10 , depression and apnea of sleep and urinary incontinence 11 in comparison With a control group.

Interventions Traditional treatment A loss target was set Gives weight of 5 to 10% of body weight. To the participants cipantes of this group were invited to attend consultations monthly during the 3 months of the study. It was awarded an advice, provided by the intern nutritionist in social service, which consisted of nutritional guidance tional, where feeding guides were explained as The Dish of Good Eating 20 , recommendation of physical activity, water and fiber consumption. He calculated the total energy expenditure, a restriction of 500 was made at 1000 calories and a meal plan was granted based on the Mexican Equivalent Food System tes 21 . The consultation time was 40 minutes for the first time and 15-20 minutes for consultations subsequent. Intensive Lifestyle Change Program (PICEV). The participants of this group are planned he had the same weight loss goal as when treating to traditional. It worked on 3 main areas to achieve that goal: 1) Behavior change protocol. It was provided to each participant a color manual of the “Equi- librio de Lifestyle ® ”(protocol implemented in the Diabetes Prevention Program) 7 . Said manual It can be obtained free of charge at: http: //www.diabetes- prevention.pitt.edu/index.php/for-the-public/group-lifes- tyle-balance-materials /. The program manual was revised in group sessions of 1.5 hours weekly, during 3 months of intervention (12 sessions in total). They are set a goal for physical activity of 150 minutes per week (2.5 hours), which should be achieved in a free way dual, as well as a goal of reducing consumption of fat, which ranged from 33 to 55 grams. The participants tes made a record of food consumed and a history of physical activity minutes as well as homework contained in each session, which were reviewed so much in the group session, as in the consultation. 2) Individualized nutritional consultation. The participants cipantes attended weekly consultation with the nu- internship triologist in social service, with a duration of one hour the first time, and 20-30 minutes I consulted them later tas. The intern nutritionist in social service granted a hypocaloric diet of 1200-1800 kcal / day (depending on the participant's energy expenditure) with macronutrient distribution of approximately 55% of carbohydrates, 20% protein and 25% gram s 22 . Within the meal plan, a meal replacement in the morning and one at night during the first month of intervention. The second month, full menus were given, five-stroke measure and last month we worked on teaching Mexican System of Equivalent Foods. In the Subsequent consultations checked the weight, progress of goals, adherence to the meal plan, between others. In case the participant is missing some se- sion or consultation, phone calls were made to schedule an appointment and monitor progress in case The patients did not attend the consultation. 3) Meal replacement. To each participant of the PICEV group, a food supplement was provided mentice (commercial smoothie) of 1 kg, similar to the one used in previous studies 8.23 and it was recommended that They will go for 2 meals a day (breakfast and dinner) during the first month. Subsequently, it was recommended to prepare milkshakes with homemade foods, based on milk Skim, seasonal fruits, oilseeds (such as almond, walnut or peanut) and fiber (5 grams of fi- bra psyllium ). The participants had the option of choose a meal plan developed by the nutritionist logo, from the beginning, if it were not your preference the use of food replacement. Training of internship nutritionists in service Social It was provided to the intern nutritionist in social service of the PICEV group a training in the management of obesity that contemplated readings and seminars (approxi- 25 hours) addressing the following topics on obesity: Epidemiology, causes, consequences cias, benefits of losing weight, review of the litter- The effectiveness of interventions for management jo of obesity in the first level and of the programs Page 4 11/20/2019 Management of obesity in the first level of care with an intensive lifestyle change program https://translate.googleusercontent.com/translate_f 4/9 1529 Nutr Hosp. 2015; 32 (4): 1526-1534 Management of obesity in the first level of attention with an intensive program lifestyle change Intensive lifestyle change, review of the efficacy in the management of obesity with different types of diets and meal replacements, clinical evaluation of the patient with obesity, behavioral strategies.

Measurement of interest variables For weight taking a digital scale was used (Model 872, Seca Gmbh & Co., Hamburg, Germany- girl; capacity 200 ± 0.05 kg), the size was used a portable stadiometer (model 213, Seca Gmbh & Co., Hamburg, Germany; capacity 20-205 ± 0.1 cm) following the techniques recommended by Suaver- za and Haua 24 . The BMI was calculated by dividing the weight of the person (kilograms) between the square of his size in meters (kg / m 2 ). The criteria of the Organization were used World Health Standardization (WHO) for classification tion of their nutritional status (overweight, obesity I and Obesity II) 25 . The waist was measured at the level of the scar umbilical and hip at maximum extension level of the buttocks 24 , using an anthropometric tape fiberglass (GÜLICK brand with scale from 0 to 150 cm) For the measurement of bicipital folds and tricipital 24 a harpenden brand plyometer was used, Model CE 0120 (Co. DJM Tanner, England; opening 80 mm and accuracy 0.2 mm.). Density was estimated body with the Durning prediction equation and Womersley 26 , the percentage was subsequently estimated of fat with the Siri equation. Once the body fat percentage, the participants were classified Pantes such as: 1) Healthy, 2) High in fat and 3) Obe- sity, as indicated by the guidelines of the Or- World Health award 27 . Pressure taking arterial was carried out with the use of a hand Omron brand meter, model HEM-7200 INT (Omron Healthcare Co., Ltd, USA), under the guidelines of the Official Mexican Standard-030 28 Statistic analysis Differences in baseline characteristics and changes in the variables of interest at 3 months are carried out by the t-test for samples Dependents for variables with normal distribution and Mann-Whitney U test in case of variables with non-normal distribution. Normality was verified of distributions through the Shapi test- ro-Wilk W., D'Agostino Skewness, Kurtosis and the cur- It is normal. In the comparison of proportions Chi square test was used. The analyzes of comparison of the changes between both groups is performed only with conservative analyzes by intention to treat. A value of p ≤ 0.05 was considered, using two-tailed test as a criterion for in- Dicar statistical significance. In the intentional analysis To discuss, all participants included were randomized at the beginning, regardless of the level of adherence to treatments.

Every year Statistical lysis was performed with the NCSS program 2009 (Number Cruncher Statistical System, Kaysville, UT, USA). Results Participants A total of 51 individuals were evaluated, of which only 42 participants met the criteria of inclusion. In the PICEV group, 21 individuals received the assigned intervention was rung and there were three interruptions premature (Fig. 1).

On the other hand, among the limitations nes of the study, it should be noted that the study was limited to a health center so it is not representative of the first level of attention. Also, the period intervention is only in the short term, so require studies with long-term follow-up. Conclusions The present study shows preliminary evidence that a PICEV can be an effective alternative to Obesity treatment at the first level of care tion. Similar interventions are required to this work but of greater duration and representativeness of first level of attention, which allow to generalize the findings found. Interest conflict None.
