Abstract :
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. Design: Community outreach
intervention with a quasi-experimental design. Participants and setting: 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.
intervention: 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. Measurements:
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 postintervention,
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). conclusion: 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.
