title: [Association between overweight and early childhood caries].
abstract: OBJECTIVE
  To determine whether overweight is a risk factor for the development of early childhood caries (ECC) in preschoolers.
  
  
  METHODS
  An observational retrospective cohort study was performed in 196 children under 2 years of age at Calbuco Hospital, Los Lagos Region, Chile, who were admitted between 2007 and 2009. Patients were grouped based on their nutritional status at admission in the two following categories: eutrophic and overweighed children as a result of excessive intake. Information regarding caries incidence and nutritional status were annually retrieved from records until the age of 5 years, according to medical and dental records.
  
  
  RESULTS
  At the beginning of the study, 33.67% were overweight and 16.33% were obese, reaching 40% overweight and 20.56% obese at four years of age. The incidence of early childhood caries in overweighed children was 57.14% compared to 40.82% in normal weight children (p = 0.022), with 1.4 RR (95% CI, 1044-1.88).
  
  
  CONCLUSIONS
  The increased risk of early childhood decay in overweighed patients makes necessary to create instances of timely mutual referral between the professional that diagnoses overweighed children and the pediatric dentist in order to develop preventive treatments for both diseases.
