Busyness (the density of activities) and daily routine (patterns of organizing time) are two understudied factors that likely impact medication-taking behaviors. We examined the association between busyness and routine with medication adherence (MA) in 405 older adults with adequate cognition using multivariable models. The final model included an interaction term between daily routine and busyness. MA scores (measured by the ASK-12, higher scores mean more barriers to adherence) were higher for individuals reporting low and moderate levels of daily routine versus those with high daily routine. MA scores were higher for individuals reporting moderate and high busyness versus those reporting low busyness. The busyness/routine interaction term was significant for MA; among highly busy individuals, those with high daily routine had lower MA scores than those with low routine. A daily routine may be a modifiable factor for improving MA among older adults, particularly among those with busy lives.

忙碌（活动密度）和日常生活（安排时间的方式）是可能影响服药行为的两个未被充分研究的因素。我们使用多变量模型检查了 405 名具有足够认知能力的老年人的忙碌和常规与药物依从性 (MA) 之间的关联。最终模型包括日常生活和忙碌之间的交互项。MA 分数（由 ASK-12 衡量，分数越高意味着坚持的障碍越多）对于那些报告日常生活水平低和中等水平的人与那些日常生活水平高的人相比更高。报告中度和高度忙碌的个人与报告低度忙碌的人相比，MA 得分更高。忙碌/日常交互项对 MA 很重要；在非常忙碌的人中，日常活动多的人的 MA 分数低于日常活动少的人。日常生活可能是改善老年人 MA 的一个可修改因素，尤其是那些生活忙碌的人。
