简要总结
This pilot study will provide a theory-based low-cost and easy-to-operate program in the area of healthy lifestyle promotion among community dwelling older adults. The blended intervention product will be helpful for health professionals, social workers and practitioners working in the elderly centers and health centers to promote older adults' PA, healthy diet and wellness. Furthermore, this study would initiate advocacy for policymakers to disseminate cost-saving, time-efficient and effective healthy lifestyle programs to the communities for healthy aging promotion.
详细描述
Project Objectives
- To review and meta-analyze lifestyle interventions for promotion of physical activity, diet and health among older adults.
- To assess the feasibility of the pilot study.
- To assess acceptability of the pilot study.
- To examine between-group differences in changes of physical activity (min/week), diet (portion/day), physical health-related outcomes (physical fitness, blood pressure, fasting blood sugar, and blood lipids), mental health-related outcomes (depression, loneliness) and health-related quality of life (QoL) among the sample.
A series of generalized linear mixed models (GLMM) will be applied to evaluate the intervention effects on outcome measures at T2, with time, groups, and their interaction as fixed effects. Per-protocol analyses will be used for primary analyses, while intention-to-treat approach will be used for sensitivity tests.

结局指标
主要结局
Change of weekly Physical activity (minutes per week)
时间窗: Change from baseline to10 week follow-up
Walking; moderate physical activity; vigorous physical activity The waist-worn accelerometer will be used to objectively assess PA (GT3X+, ActiGraph Inc, Pensacola, FL, USA). The Chinese version of the International Physical Activity Questionnaire-short form (IPAQ-C). If there is an increase, the result means a better outcome.
Change of Meat, Fish, Egg & Alternatives (MFEA) (taels/day)
时间窗: Change from baseline to10 week follow-up
To assess the Meat, Fish, Egg \& Alternatives consumption, individuals will be asked to answer three items. To assess the Meat, Fish, Egg \& Alternatives during the past seven days, participants will be asked "how many taels of meat do they have today", "how many taels of eggs do they have today" and "how many taels of Alternatives do they have today". Participants were asked to keep a record for seven days, then to get an average intake of Meat, Fish, Egg \& Alternatives for each day. If there is a change, and the follow-up result is between 5 and 6, the result is better.
Change of Fruit and Vegetable Intake (portions/day)
时间窗: Change from baseline to10 week follow-up
To assess the fruit and vegetable intake during the past seven days, participants will be asked "how many portions of fruit they have today" and "how many portions of vegetables they have today". Participants were asked to keep a record for seven days, then to get an average for each day. If there is an increase, the result means a better outcome.
