title: Low social support level is associated with non-adherence to diet at 1 year in the Family Intervention Trial for Heart Health (FIT Heart).
abstract: OBJECTIVE
  Evaluate the relationship between low social support (SS) and adherence to diet in a cardiovascular disease (CVD) lifestyle intervention trial.
  
  
  METHODS
  Prospective substudy.
  
  
  METHODS
  Blood relatives/cohabitants of hospitalized cardiac patients in a randomized controlled trial (n=458; 66% female, 35% nonwhite, mean age 50 years).
  
  
  METHODS
  Non-adherence to diet using MEDFICTS (Meats, Eggs, Dairy, Fried foods, fat In baked goods, Convenience foods, fats added at the Table, and Snacks) tool; SS using the Enhancing Recovery in Coronary Heart Disease Patients Social Support Instrument.
  
  
  METHODS
  Logistic regression models adjusted for confounders.
  
  
  RESULTS
  Significant predictors (P<.05) of non-adherence to diet recommendations at 1 year included low SS, increased body mass index and waist size, lower physical activity, depression, pre-action stages of change, control group assignment, and being male. Those with low SS at baseline 2.7 greater odds of being non-adherent to diet at 1 year vs those with higher SS (95% confidence interval=1.1-6.4); there was no interaction by group assignment.
  
  
  CONCLUSIONS
  Low SS at baseline was independently associated with non-adherence to diet at 1 year, suggesting that family members with low SS may be at heightened CVD risk as a result of poor dietary adherence.
