“The term hidden elder is used in Chinese society to describe older adults who are socially isolated and refuse social participation. Substantial evidence has indicated the important role of social isolation in increasing psychiatric morbidity and mortality risks in later life.“
 
”Innovative service is promptly needed to address the social and psychological health needs of hidden elders. We aimed to test the feasibility and the preliminary effectiveness of a peer-assisted tai-chi-qigong programme in strengthening social networks and enhancing psychosocial wellbeing of Chinese hidden elders.”
.
”In the 3-month tai-chi-qigong programme, participants practiced two 60-min sessions each week, during which they were paired up with socially active older adults.“
.
”Participants who received the peer-assisted tai-chi-qigong programme generally showed better improvement in outcomes than the control group. With support from peer elders, the compliance rate of elders participating in tai-chi-qigong was 71%.”
.
“This pilot study showed that peer-assisted tai-chi-qigong is a feasible social intervention for hidden elders. A full-scale trial is needed to assess the possible benefits for social and physical health.”

“In a large sample of Chinese oldest old, we found a dose-response association between psychological wellbeing and all-cause mortality. Our results, if substantiated by future research, suggest that psychological factors in older age might have a role in longevity.”
