The aim of the study is to determine dietary lutein and zeaxanthin (/) consumption and to evaluate its association with macular pigment optical density (MPOD) in Thai subjects. . This study was a cross-sectional study. A total of 120 ophthalmologically healthy subjects aged between 40 and 72 years were recruited from Bangkok and the vicinity area. Demographic data were collected using a questionnaire, while a semiquantitative food frequency questionnaire assessed the / intake. MPOD was determined using the reflectometry method (VISUCAM 500®, Carl Zeiss Meditec AG). Pearson's correlation coefficient analyzed the relationship between / consumption and MPOD. . The mean age of the participants was 50.7 ± 7.5 years. The mean consumption of / was 3.03 ± 2.65 mg per day. The mean MPOD was 0.102 ± 0.023 density units. Consumption of foods rich in /, including ivy gourd ( = 0.217, < 0.05), Chinese flowering cabbage ( = 0.194, < 0.05), balsam pear ( = 0.193, < 0.05), lettuce ( = 0.182, < 0.05), sweet corn ( = 0.181, < 0.05), and pumpkin ( = 0.181, < 0.05), was positively associated with the mean optical density (mean MPOD). Consumption of green onion ( = 0.212, < 0.05) was positively associated with the sum of optical densities (MPOD volume). In contrast, chilli pepper consumption showed a negative association with mean MPOD ( = -0.220, < 0.05) and amaranth showed a negative association with MPOD volume ( = -0.283, < 0.05). No association was found between total / consumption and MPOD. . / consumption is low among Thais living in Bangkok and the vicinity area, which may not be sufficient to ensure eye health, and total / consumption is not associated with MPOD.
该研究的目的是确定泰国受试者的膳食叶黄素和玉米黄质（/）摄入量，并评估其与黄斑色素光密度（MPOD）的关联。本研究为横断面研究。从曼谷及其周边地区招募了120名年龄在40至72岁之间的眼科健康受试者。使用问卷收集人口统计学数据，同时通过半定量食物频率问卷评估/摄入量。使用反射ometry方法（VISUCAM 500®，卡尔蔡司医疗技术股份公司）测定MPOD。皮尔逊相关系数分析了/摄入量与MPOD之间的关系。参与者的平均年龄为50.7±7.5岁。/的平均摄入量为每天3.03±2.65毫克。平均MPOD为0.102±0.023密度单位。食用富含/的食物，包括丝瓜（=0.217，<0.05）、小白菜（=0.194，<0.05）、苦瓜（=0.193，<0.05）、生菜（=0.182，<0.05）、甜玉米（=0.181，<0.05）和南瓜（=0.181，<0.05），与平均光密度（平均MPOD）呈正相关。食用葱（=0.212，<0.05）与光密度总和（MPOD体积）呈正相关。相比之下，食用辣椒与平均MPOD呈负相关（= -0.220，<0.05），食用苋菜与MPOD体积呈负相关（= -0.283，<0.05）。未发现总/摄入量与MPOD之间存在关联。居住在曼谷及其周边地区的泰国人的/摄入量较低，这可能不足以确保眼部健康，且总/摄入量与MPOD无关。
