| Methods |
Study design: RCT Duration of study: the study was conducted from October 2017 to July 2018. Country: China Income classification: upper‐middle‐income country from 2017 to 2018 Geographical scope: urban—Hangzhou City Healthcare setting: 2 community health centres |
| Participants | 1. Age: 75.78 ± 6.28 years old 2. Gender: both 3. Socioeconomic background: 60+% had a monthly income < average value in the local city. 4. Educational background: less than 20% were illiterate. Inclusion criteria: a. community‐dwelling elderly people aged 60 or above; b. identified with mild cognitive impairment by the Montreal Cognitive Assessment (Chinese version, MoCA‐C). Exclusion criteria: a. participants with conditions that were contraindicated for exercise training according to the American College of Sports Medicine (ACSM); b. prescription of antidepressant agents, which may confound the outcome measurement; c. severe neurological disorders (e.g. brain injury, stroke, Parkinson’s disease) which greatly impair cognitive function; d. regular engagement in moderate or vigorous‐intensity aerobic exercises of > 150 min per week. Note: at baseline, the intervention and control group scores for Geriatric Depression Scale (GDS) were, respectively, 5.33 (3.48) and 5.67 (3.7). At baseline, the intervention and control group scores for Quality of Life—Alzheimer’s disease scale (QOL‐AD) were, respectively, 29.80 (3.23) and 29.18 (2.70). Stated purpose: to evaluate the effects of a moderate‐intensity aerobic exercise programme on the cognitive function and health‐related quality of life of Chinese elderly with mild cognitive impairment and to explore the mediating roles of depressive mood and sleep quality in the exercise‐cognition relationship. |
| Interventions |
Name: moderate‐intensity aerobic exercise training Title/name of PW and number: nurses (2) 1. Selection: not specified 2. Educational background: registered nurses 3. Training: 4‐week training programme 4. Supervision: the nurses performed a return demonstration during the training and exhibited good protocol compliance. 5. Incentives/remuneration: not specified Prevention type: indicated – participants presented with some level of distress as indicated by GDS scores. Intervention details: 16‐week aerobic stepping exercise programme with three 60‐minute group training sessions (20 participants per group) per week. Motivational strategies, including goal‐setting, verbal encouragement, and emotional incentives based on the self‐efficacy theory, were incorporated into this exercise intervention to ensure compliance. Control: active control – the control intervention was a 16‐week health education programme that was delivered by a general practitioner in the community healthcare centre. The health education programme included eight biweekly educational classes (45 min/each session). No information relating to brain health and physical exercise was included. |
