title: [EFFICACY OF SELF-MONITORING IN WEIGHT LOSS: A SYSTEMATIC REVIEW OF RANDOMIZED CONTROLLED STUDIES].
abstract: BACKGROUND
  different studies have shown a strong relationship between self-monitoring and weight loss. The objective of this review was to analyze randomized clinical trials using self-monitoring as a strategy for weight loss.
  
  
  METHODS
  a search was conducted in PubMed database of randomized controlled trials using self-monitoring for weight loss in adults, published in English and Spanish, from January 1st, 2009 to April 30th, 2015. The sample size, age, weight loss, BMI, intervention strategy, duration, and retention rate, were recorded.
  
  
  RESULTS
  six studies met the selection criteria. The intervention and the follow-up ranged from 3 to 12 months. The study population ranged from 18-74 years of age and included subjects from 50-329. Weight loss ranged from 1.14 to 2.1 kg in the control group and -1.27 to -6.1 kg in the intervention group. The six studies determined a greater weight loss in the self-monitoring group with moderate to high evaluation evidence.
  
  
  CONCLUSIONS
  greater weight loss was consistently found in the self-monitoring group. These results suggest the need to use self-monitoring as a strategy for weight loss.
