本研究的目的是调查的频率一起吃饭和老年人的体重减轻的风险之间的关系。MethodsThis是一个为期三年的后续前瞻性队列研究的基础上自我报告的问卷调查。我们使用了2016年和2019年进行的日本老年学评估研究（JAGES）的数据。参与者为日本年龄≥65岁的独立老年人。我们使用随访期间体重减轻>5%作为结果变量，一起吃饭的频率作为解释变量。相对危险度（RR）和95%置信区间（95%CI）的基础上估计的泊松回归模型与Huber-White三明治估计的标准误，包括可能的confounders.Resultsamong 56,919参与者，平均年龄为73.0岁（1 SD = 5.5）在基线，47.9%是男性。大约15.1%（n= 8，596）的参与者在随访期间体重减轻>5%。“每天”、“一周几次”、“一月几次”、"一年几次“和”很少“的比例分别为36.6%、10.3%、26.8%、20.5%和5.8%。与'每天'相比，只有'一年几次（RR = 1.07，95%CI = 1.01-1.13）“和”很少（RR = 1.17，95%CI = 1.08-1.27）“与>5%的风险增加显著相关结论：在独立个体中，不经常一起吃饭与体重减轻风险增加之间存在时间关联。老年人
Objectivethe present study aimed to investigate the relationship between the frequency of eating together and the risk of weight loss in older adults.Methodsthis was a three-year follow-up prospective cohort study based on a self-reported questionnaire. We used data from the Japan Gerontological Evaluation Study (JAGES) conducted in 2016 and 2019. The participants were independent older adults aged ≥65 years in Japan. We used >5% weight loss during follow-up as the outcome variable and frequency of eating together as the explanatory variable. The relative risks (RRs) and 95% confidence intervals (95% CIs) were estimated based on the Poisson regression model with a Huber–White sandwich estimator for standard errors, including possible confounders.Resultsamong 56,919 participants, the mean age was 73.0 years (1SD = 5.5) at baseline, and 47.9% were male. About 15.1% (n= 8,596) of the participants experienced >5% weight loss during follow-up. The proportion of each category of the eating together frequency was 36.6% for ‘every day’, 10.3% for ‘several times a week’, 26.8% for ‘several times a month’, 20.5% for ‘several times a year’ and 5.8% for ‘seldom’. Compared to ‘every day’, only ‘several times a year (RR = 1.07, 95% CI = 1.01–1.13)’ and ‘seldom (RR = 1.17, 95% CI = 1.08–1.27)’ were significantly associated with the increased risk of >5% weight loss.Conclusionthere is a temporal association between less frequent opportunities to eat together and the increased risk of weight loss among independent older adults.
