对东京八王子市西部65岁以上独居老人进行了一项横断面调查，调查其维生素A、B1和C的状况及相关因素。在 159 名受试者中，有 17 名男性和 81 名女性参与了这项调查。对社会经济状况、健康状况、生活方式和饮食习惯进行问卷调查和访谈，并进行体检并采集血液并进行分析。分别根据血清维生素A浓度、全血维生素B1浓度和血清维生素C浓度评估维生素A、B1和C状态。大多数参与者都是日常生活中比较活跃的人。 33% 的参与者被评估为维生素 B1 状况不佳，而分别有 1% 和 4% 的参与者被评估为维生素 A 和 C 状况不佳。全血维生素 B1 与血清维生素 A 浓度之间以及全血维生素 B1 与血清维生素 C 浓度之间存在显着相关性。大约 10% 的参与者血液维生素 B1 浓度低于 35 ng/ml，同时血清维生素 A 和 C 浓度显着低于其他人。因此，营养摄入不足或饮食摄入不当被认为是一个原因。虽然良好的维生素状况与使用维生素制剂或维生素补充剂有关，但维生素状况较低与饮食习惯或行为密切相关，例如对食物组合的饮食漠不关心、更偏爱大米作为主食以及据报道准备膳食有困难。
A cross-sectional survey was performed to examine the vitamin A, B1 and C status and relating factors among the elderly aged over 65 years and living alone in the western parts of Hachioji, Tokyo. Of 159 subjects, 17 men and 81 women participated in this survey. A questionnaire and interview on the socioeconomic conditions, state of health and life-style and easting habits, and a medical examination were conducted and blood collected and analyzed. Vitamin A, B1 and C status was evaluated on the basis of serum vitamin A concentration, whole blood vitamin B1 concentration and serum vitamin C concentration, respectively. Most of the participants were those who were comparatively active in daily life. Thirty-three percent of the participants were assessed to be in poor vitamin B1 status, while 1% and 4% were assessed to be in poor vitamin A and C status, respectively. Significant correlations were found between whole blood vitamin B1 and serum vitamin A concentrations and between whole blood vitamin B1 and serum vitamin C concentrations. About 10% of the participants had blood vitamin B1 concentrations as below 35 ng/ml and at the same time, significantly lower serum vitamin A and C concentrations than others. Thus, inadequate nutrient intakes or inappropriate diet intakes were suggested as a cause. While good vitamin status was linked with use of vitamin preparations or vitamin supplements, lowered vitamin status was found to be closely associated with such dietary practices or behavior as dietary indifference to food combinations, a higher preference of rice as the staple food and having a reported difficulty in preparing meals.
