This study aimed to examine whether eating alone, folate intake, and n-3 PUFA intake are independently associated with psychological distress in older adults.
We analyzed cross-sectional data from 1011 study participants aged ≥65 years in Japan. We assessed psychological distress using the Kessler 6 scale, whether the participants ate alone or with others, folate and n-3 PUFA intake using a short food frequency questionnaire.
Of the 1011 study participants, 465 (46.0%) were male and mean (SD) age was 71.6 (4.8) years. In a multivariable logistic regression analysis, the odds ratio (OR) for psychological distress in participants eating alone compared to those eating with others was 1.32 (95% confidence interval [CI], 0.76-2.31). The ORs in the second and third tertiles com-pared to the first tertile, which had the lowest folate intake, were 0.92 (95% CI, 0.62-1.37) and 1.12 (95% CI, 0.73-1.73), respectively. The ORs in the second and third tertiles compared to the first tertile, which had the lowest n-3 PUFA intake, were 0.83 (95% CI, 0.56-1.24) and 0.95 (95% CI, 0.62-1.45), respectively. Also, the OR in those eating alone combined with the first tertile of n-3 PUFA intake compared to those eating with others with the third tertile was 2.18 (95%CI, 1.05-4.55).
Although eating alone combined with low n-3 PUFA intake was associated with psychological distress in older adults, eating alone, folate intake, and n-3 PUFA intake were not independently associated with psychological distress.
本研究旨在探讨独自用餐、叶酸摄入量和n-3多不饱和脂肪酸摄入量是否与老年人的心理困扰独立相关。
我们分析了来自日本1011名年龄≥65岁研究参与者的横断面数据。我们使用凯斯勒6项量表评估心理困扰，通过简短食物频率问卷评估参与者是独自用餐还是与他人一起用餐、叶酸和n-3多不饱和脂肪酸的摄入量。
在1011名研究参与者中，465名（46.0%）为男性，平均（标准差）年龄为71.6（4.8）岁。在多变量逻辑回归分析中，独自用餐的参与者与与他人一起用餐的参与者相比，心理困扰的比值比（OR）为1.32（95%置信区间[CI]，0.76 - 2.31）。与叶酸摄入量最低的第一三分位数相比，第二和第三三分位数的OR分别为0.92（95%CI，0.62 - 1.37）和1.12（95%CI，0.73 - 1.73）。与n-3多不饱和脂肪酸摄入量最低的第一三分位数相比，第二和第三三分位数的OR分别为0.83（95%CI，0.56 - 1.24）和0.95（95%CI，0.62 - 1.45）。此外，独自用餐且n-3多不饱和脂肪酸摄入量处于第一三分位数的参与者与与他人一起用餐且n-3多不饱和脂肪酸摄入量处于第三三分位数的参与者相比，OR为2.18（95%CI，1.05 - 4.55）。
尽管独自用餐且n-3多不饱和脂肪酸摄入量低与老年人的心理困扰相关，但独自用餐、叶酸摄入量和n-3多不饱和脂肪酸摄入量并非与心理困扰独立相关。
