不同国家的饮食摄入量与健康结果之间的关联存在差异，尤其是在老年人中。我们使用金标准饮食评估方法，一个称重的食物记录，检查饮食模式和死亡率之间的关系，在一个代表性的样本，来自英国的社区居住参与者年龄在65岁及以上。在基线时记录了1017名老年参与者（520名男性，497名女性，平均年龄76.3±7.4岁）的饮食摄入量。研究人员进行了探索性因素分析，以检查饮食模式，并对参与者的死亡率进行了平均9.2年的随访。因子分析显示四个可解释的主成分约占总方差的9.8%，性别间的模式相似。“地中海式”的饮食模式解释了最大比例的变异（3.7%），其次是“健康意识”（2.2%），“传统”（2.0%）和“甜和脂肪”（1.9%）的因素。随访期间共有683例死亡。调整潜在混杂因素后，只有地中海式饮食模式仍与死亡率相关（最高vs最低三分位数;风险比=0.82，95%CI，0.68-1.00）。地中海式饮食的益处仅在女性中观察到（风险比=0.71，95% CI 0.52-0.96），尽管在男性中传统饮食是死亡率的风险因素（风险比=1.30，95% CI 1.00-1.71）。使用金标准方法，我们的研究结果证实了先前的证据，即饮食模式对老年人的长寿很重要。
There is variability in the association between dietary intake and health outcomes across different countries, especially among the elderly. We used the gold standard dietary assessment method, a weighed food record, to examine the association between dietary pattern and mortality in a representative sample of community dwelling participants from Great Britain aged 65 years and older. Dietary intake was recorded at baseline in 1017 elderly participants (520 men, 497 women, mean age 76.3±7.4 years). Exploratory factor analysis was performed to examine dietary patterns and participants were followed up over an average of 9.2 years for mortality. The factor analysis revealed four interpretable principal components accounting for approximately 9.8% of the total variance, with similar patterns across sex. A ‘Mediterranean-style’ dietary pattern explained the greatest proportion of the variance (3.7%), followed by ‘health-aware’ (2.2%), ‘traditional’ (2.0%) and ‘sweet and fat’ (1.9%) factors. There were a total of 683 deaths through follow-up. After adjustment for potential confounders, only the Mediterranean-style dietary pattern remained associated with mortality (highest vs lowest tertile; hazard ratio=0.82, 95% CI, 0.68–1.00). The benefits of the Mediterranean-style diet were only observed among women (hazard ratio=0.71, 95% CI 0.52–0.96) although in men the traditional diet was a risk factor for mortality (hazard ratio=1.30, 95% CI 1.00–1.71). Using a gold standard approach, our results confirm previous evidence that dietary patterns are important in longevity among the elderly.
