除了强度和质量外，活动的多样性将是解释老年人健康结果的一个重要因素。然而，很少有研究调查了活动多样性和健康结果之间的关系。本研究旨在探讨日本社区老年人活动多样性与身体虚弱之间的关系。参与者是社区居住的老年人，他们参加了2018年的队列研究“Otassya-Kenshin”。被试被要求在一周内进行20项日常活动、室内/室外家务、有/没有体力活动、与朋友直接/间接接触等活动的频率，并使用香农熵公式计算活动多样性得分。虚弱是由日本版的心血管健康研究标准定义的。体弱组与非体弱组的多样性评分差异采用t检验。采用协变量、年龄、性别、经济状况、独居、BMI、Mini-Mental State Examination和IADL进行Logistic回归分析，寻找活动多样性评分与虚弱存在的相关性。在分析的652名参与者（年龄：72.8±6.3，女性：60.6%）中，27名（4.1%）被定义为虚弱。虚弱组活动多样性评分明显低于非虚弱组（0.66±0.11 vs 0.75±0.08，P<0.01）。控制协变量后，多样性得分每降低0.2分，脆弱几率增加5倍。我们发现老年受试者的活动多样性与健康结果之间存在显著关系。活动多样性可以为活动的数量或强度提供额外的信息。
In addition to intensity and quality, diversity of activity will be an important factor to explain health outcomes among older adults. Few studies, though, examined an association between activity diversity and health outcomes. This study aimed to examine the association between activity diversity and frailty among community-dwelling older Japanese. Participants were community-dwelling older adults who participated in a cohort study, the “Otassya-Kenshin” in 2018 . The participants were asked frequency of 20 daily activities, inside/outside chores, leisure activities with/without physically, direct/indirect contact with friends and so on, in a week and activity diversity score were calculated using the formula of Shannon’s entropy. Frailty was defined by the Japanese version of the Cardiovascular Health Study criteria. The difference in diversity score between frail and non frail were examined by t-test. Logistic regression analysis with covariates, age, sex, economic status, living alone, BMI, Mini-Mental State Examination, and IADL was adopted to find association between activity diversity score and presence of frailty. Of 652 participants (age: 72.8±6.3, women: 60.6%) analyzed, 27 (4.1%) were defined as frail. Frailty group revealed significantly lower activity diversity score than non-frailty group (0.66±0.11 vs 0.75±0.08, P<0.01). 0.2 point of decrease in diversity score increase 5 times chance of frailty after controlling covariates. We found significant relationship between activity diversity and health outcome among older subjects. The activity diversity may provide additional information to number or intensity of activity.
