Characterize vegetable and fruit (VF) intake in a Yup'ik community using self-reported intake and skin carotenoid status (SCS) and evaluate the relationship between SCS and fish intake.
Self-reported VF intake was measured using the 24-hour recall, SCS was measured by reflection spectroscopy via the Veggie Meter (Longevity Link Corporation), and fish intake was estimated by the nitrogen isotope ratio (NIR) for 80 participants in a remote community in Southwestern Alaska. Bivariate correlations were used to assess the relationship between self-reported VF intake, SCS, and NIR.
Intake of all VF subgroups was low. The SCS was higher for males (262.7 vs 185.3; P = 0.002) and participants consuming more than 1 VF serving (232.5 vs 183.0; P = 0.02). It was not associated with the NIR.
Increasing VF intake is a way to improve diet in Yup'ik communities and the Veggie Meter is a simple and noninvasive tool to facilitate surveillance efforts.
使用自我报告摄入量和皮肤类胡萝卜素状况 (SCS) 来描述Yup'ik 社区的蔬菜和水果 (VF) 摄入量，并评估 SCS 与鱼类摄入量之间的关系。
通过 24 小时回忆法测量自我报告的 VF 摄入量，通过反射光谱法通过 Veggie Meter（长寿链接公司）测量 SCS，通过氮同位素比 (NIR) 估计 80 名生活在阿拉斯加西南部偏远社区的参与者的鱼类摄入量。使用双变量相关性来评估自我报告的 VF 摄入量、SCS 和 NIR 之间的关系。
所有 VF 亚组的摄入量都很低。男性的 SCS 更高（262.7 与 185.3；P=0.002），并且摄入超过 1 份 VF 食物的参与者的 SCS 更高（232.5 与 183.0；P=0.02）。它与 NIR 无关。
增加 VF 摄入量是改善Yup'ik 社区饮食的一种方法，而 Veggie Meter 是一种简单且非侵入性的工具，可以促进监测工作。
