The aim was to evaluate dietary intakes and their correlation to some risk factors for coronary heart disease.
The study was a population based survey with random sample selection stratified by age and sex.
352 adults living in a small town in Northern Italy took part in the study. Response rate was 46% among females and 48% among males. Refusal to take part was mainly due to the large number of tests involved.
Diets were high in protein (animal/vegetable ratio 1.7 in women and 1.4 in men) and in fat and low in carbohydrates. The hypercholesterolaemic and atherogenic potential of the diet, evaluated by the cholesterol/saturated fat index, was high in about 50% of the population. The thiamin and riboflavin intakes were lower than the Italian recommended allowances in more than 60% of the people tested, whereas the vitamin A intake was more than adequate in about 70%. A positive association was found in the younger groups (men and women 20-39 years old) between some nutrient components (energy, alcohol, total and saturated fats) and some blood lipids. In the older people blood lipids were correlated with body mass index.
The overall data indicate that a correlation exists between dietary intake and some risk factors for coronary heart disease; dietary intervention, at least in young adults, is suggested.
旨在评估饮食摄入量及其与冠心病某些危险因素的相关性。
该研究是一项基于人群的调查，通过按年龄和性别分层进行随机抽样。
352名居住在意大利北部一个小镇的成年人参与了该研究。女性的回应率为46%，男性为48%。拒绝参与主要是因为涉及大量检测。
饮食中蛋白质含量高（女性动物蛋白/植物蛋白比例为1.7，男性为1.4）、脂肪含量高且碳水化合物含量低。通过胆固醇/饱和脂肪指数评估，约50%人群的饮食具有高胆固醇血症和致动脉粥样硬化潜力。超过60%的受测者硫胺素和核黄素摄入量低于意大利推荐摄入量，而约70%的人维生素A摄入量充足。在较年轻组（20 - 39岁的男性和女性）中，某些营养成分（能量、酒精、总脂肪和饱和脂肪）与某些血脂之间存在正相关。在老年人中，血脂与体重指数相关。
总体数据表明饮食摄入量与冠心病某些危险因素之间存在相关性；建议至少对年轻人进行饮食干预。
