HE was a 12-week program that included 24 training courses on cognitive health. Specifically, the HE project focused on the determination of participants’ risk and early identification of cognitive impairment. It provided health guidance on maintaining cognitive function around the risk and on protective factors of cognitive impairment, such as dietary advice, methods of physical exercise, and memory strategies in daily life. Participants in the HE group were required to receive 30–60 min of cognitive HE provided by geriatric nurses in the hospital twice a week. The organization mainly included live health lectures and discussion of health tweets in WeChat groups.
