缺乏身体活动是造成疾病负担的一个主要因素，在许多国家都很严重。一些初步研究表明，循环中的叶黄素浓度与高水平的体力活动（PA）有关。我们的目的是评估在不同国家进行的两项研究中，含叶黄素食物（包括蔬菜和鸡蛋）的摄入量是否与PA水平相关。分析了两项横断面研究参与者的饮食数据和PA数据：在美国中央纽约进行的缅因州-锡拉丘兹纵向研究（MSLS）（n = 972）和卢森堡研究心血管危险因素观察（ORISCAV-LUX）（n = 1331）。在两个研究地点，较高的叶黄素摄入量，包括绿色叶菜，与较高水平的PA相关。增加富含叶黄素的食物的消费可能会对PA水平产生积极影响。这需要在随机对照试验中进一步探索。
Levels of physical inactivity, a major contributor to burden of disease, are high in many countries. Some preliminary research suggests that circulating lutein concentrations are associated with high levels of physical activity (PA). We aimed to assess whether the intake of lutein-containing foods, including vegetables and eggs, is associated with levels of PA in two studies conducted in different countries. Dietary data and PA data collected from participants in two cross-sectional studies: the Maine-Syracuse Longitudinal Study (MSLS), conducted in Central New York, USA (n = 972), and the Observation of Cardiovascular Risk Factors in Luxembourg Study (ORISCAV-LUX) (n = 1331) were analyzed. Higher intakes of lutein containing foods, including green leafy vegetables, were associated with higher levels of PA in both study sites. Increasing the consumption of lutein-rich foods may have the potential to impact positively on levels of PA. This needs to be further explored in randomized controlled trials.
