Connect Active Programme (CAP): A Pilot RCT to Enhance Physical Activity and Intergenerational Relationships Through Dyadic Digital Walking Exercises

<b>Background/Objectives</b>: Sedentariness is a common phenomenon among both the elderly and the young in modern society. Changes in work structure, leisure activities, and technological advancements have contributed to excessive sitting time. To address sedentary lifestyles across generations, this randomised controlled pilot trial aimed to investigate the effectiveness of the Connective Active Programme (CAP) in improving intergenerational relationships, psychological well-being, and physical fitness among older adults. <b>Methods</b>: Twenty dyads of older and younger adults from the same family were recruited and randomly allocated to an experimental group or a control group in a 1:1 ratio. The experimental group participated in six weekly 2-h dyadic walking sessions supported by digital information and mobile applications, whereas the control group received weekly digital pamphlets. <b>Results</b>: Compared to the control group, the experimental group showed significant improvements in younger participants' intergenerational relationship quality, as well as in older participants' 6-Minute Walk Test performance and WHOQOL-BREF scores. <b>Conclusions</b>: The CAP appears to be a viable strategy to enhance intergenerational relationships and promote healthy ageing among community-dwelling older adults in Hong Kong.
