A pilot randomized controlled trial using Baduanjin qigong to reverse frailty status among post-treatment older cancer survivors.

OBJECTIVES: To evaluate the feasibility and potential effects of qigong Baduanjin for reversing frailty status among older cancer survivors. MATERIALS AND METHODS: Twenty-eight older cancer survivors screened as pre-frail or frail were recruited. They were randomly assigned (1:1) to receive a sixteen-week Baduanjin intervention or an active control condition (light flexibility exercise). Frailty status (primary outcome) and secondary outcomes (physical performance, activities of daily living performance, psychological well-being, and health-related quality of life) were measured by physical performance tests and questionnaires. Qualitative interviews were conducted to explore participants' perspectives on the intervention. RESULTS: Twenty-one participants (75%) completed the study, with reasons of withdrawal mainly relating to the COVID-19 pandemic. Attendance at Baduanjin sessions and adherence to self-practice were satisfactory, with all retained participants attending all sessions and 81.8% practicing Baduanjin for more than 90 min per week. Qualitative findings demonstrated that participants accepted Baduanjin. The proportion of improvement in frailty status at post-intervention appeared to be higher in the intervention group (26.7%; 95% confidence interval [CI], 10.1% to 54.0%) than the control group (15.4%; 95% CI, 3.7% to 46.0%); yet the difference was not statistically significant (p = 0.461). CONCLUSIONS: Baduanjin qigong appears to be feasible and acceptable among older cancer survivors. To confirm the intervention effect, an adequately powered trial is warranted.

Sleep and Mood Disturbances during the COVID-19 Outbreak in an Urban Chinese Population in Hong Kong: A Longitudinal Study of the Second and Third Waves of the Outbreak.

In response to the worsening situation of the COVID pandemic, this follow-up study aimed to assess the impact of the "third wave" of the outbreak on sleep and mood disturbances among Hong Kong citizens. A total of 339 respondents included in our last study during the second wave (4-11 August 2020) joined this survey (response rate = 51.1%). The questionnaire collected data on sleep conditions, mood, stress, and risk perception. The sleep quality and mood status were assessed using the Insomnia Severity Index (ISI), General Anxiety Disorder-7 (GAD-7), and Patient Health Questionnaire-9. The weighted prevalence of insomnia, anxiety, and depression was 33.6%, 15.3%, and 22.0%, respectively. Compared with the last survey, five out of six sleep parameters significantly worsened despite the lack of difference in the ISI score. The GAD-7 score was significantly lower. Old-aged adults were less likely to maintain good sleep quality compared with middle-aged adults (adjusted OR = 4.03, 95% CI: 1.04-15.73). Respondents without psychiatric disorder were more likely to be anxiety-free across the two time points (adjusted OR = 7.12, 95% CI: 1.33-38.03). One-third of Hong Kong people reported poor sleeping quality in the third wave of the COVID-19 outbreak. Policy-makers need to propose a contingent plan to allocate mental health resources to vulnerable subpopulations.
