Abstract
The effect of a behaviorally-oriented program to reduce calories and increase physical activity on HDL cholesterol level was evaluated in overweight older adult subjects (n = 31). HDL cholesterol increased from 45.8 to 52.1 mg/dl (p < .0003), and total mean cholesterol increased from 238.0 to 249.5 mg/dl (p < .05). Body weight decreased from 175.0 lbs to 172.6 lbs (p < .03). Analysis of baseline and 40 week food frequency questionnaires indicated that the mean caloric intake had decreased from 1535 to 1303 kcal/day (p < .02), and total fat intake decreased by 9.8 gm/day (p < .01). Weight loss accounted for 13% of the variance in HDL cholesterol change (p < .05). Decreasing fat intake resulted in a smaller increase in HDL cholesterol (F, (l,29) = 5.91, p < .03). Our findings provide further support that a prudent approach to weight reduction can be beneficial in an older adult population.
