title: The effects of diet education plus light resistance training on coronary heart disease risk factors in community-dwelling older adults.
abstract: OBJECTIVE
  To examine the effects of diet education (DE) plus light resistance training (RT) on coronary heart disease risk (CHD) factors, specifically dietary quality, blood lipid and C-Reactive protein (CRP) concentrations in overweight and obese older adults in a community setting.
  
  
  METHODS
  Community outreach intervention with a quasi-experimental design.
  
  
  METHODS
  A total of 96 subjects, 16 males and 80 females, aged 69.2 ± 6.2 years, community-dwelling, and from one of four senior centers in Rhode Island.
  
  
  METHODS
  Subjects participated in 30 minutes of DE (once per week) and ~80 minutes of RT (two separate sessions per week) for eight weeks. The DE sessions were led by a registered dietitian.
  
  
  METHODS
  Anthropometrics (height, weight, waist circumference, hip circumference, and body composition), clinical (blood pressure), biochemical (lipid profile, glucose, and CRP concentrations), and diet quality measured by the Dietary Screening Tool (DST).
  
  
  RESULTS
  A significant change was seen in DST risk categories from baseline to post-intervention, χ² (2)=20.43, p < 0.01. Significant differences were seen in triacylglycerol (p=0.028) as well as in systolic and diastolic blood pressures, weight, waist circumference, hip circumference, percent body fat, fat mass, and body mass index (all p<0.05).
  
  
  CONCLUSIONS
  This intervention effectively decreased CHD risk in overweight and obese older adults. Future research is needed to examine the effects of longer DE plus RT interventions with greater weight loss on the lipid profile and CRP concentrations in overweight and obese older adults at risk for CHD.
