BACKGROUND:<\/strong>
\nPoor nutrition contributes to high rates of coronary heart disease among Australian Aboriginal populations. Since late 1993, the Aboriginal community described here has operated a healthy lifestyle program aimed at reducing the risk of chronic disease.<\/p>\n

OBJECTIVE:<\/strong>
\nWe evaluated the effectiveness of a community-directed intervention program to reduce coronary heart disease risk through dietary modification.<\/p>\n

DESIGN:<\/strong>
\nIntervention processes included store management policy changes, health promotion activities, and nutrition education aimed at high-risk individuals. Dietary advice was focused on decreasing saturated fat and sugar intake and increasing fruit and vegetable intake. Evaluation of the program included conducting sequential, cross-sectional risk factor surveys at 2-y intervals; measuring fasting cholesterol, lipid-soluble antioxidants, and homocysteine concentrations; and assessing smoking status. Nutrient intakes were estimated from analysis of food turnover in the single community store.<\/p>\n

RESULTS:<\/strong>
\nThere was a significant reduction in the prevalence of hypercholesterolemia (age-adjusted prevalences were 31%, 21%, and 15% at baseline, 2 y, and 4 y, respectively; P < 0.001). There were significant increases in plasma concentrations of alpha-tocopherol, lutein and zeaxanthin, cryptoxanthin, and beta-carotene across the population. Retinol and lycopene concentrations did not change significantly. Mean plasma homocysteine concentrations decreased by 3 µmol\/L. There was no significant change in smoking prevalence between the 2 follow-up surveys. There was an increase in the density of fresh fruit and vegetables and carotenoids in the food supply at the community store.<\/p>\n

CONCLUSION:<\/strong>
\nThis community-directed dietary intervention program reduced the prevalence of coronary heart disease risk factors related to diet.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56080","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"ROWLEY KG,UNIV MELBOURNE,ST VINCENTS HOSP
