The present study is designed to to estimate the prevalence of frailty and pre-frailty and their associated factors in community-dwelling populations aged 50 years and above in Hong Kong, and to explore the views of participants taking part in a community health talks or activities on frailty about what the participants felt or had gained from participating, concerns, and suggestions for change or improvement.
A survey of 15000 people aged 50 years or older identified in community facilities will be conducted. The participants will be invited to their affiliated centres for a brief screening using the FRAIL scale and assessment. A series of community health talks or activities on frailty will be offered to the participants based on the frailty status.Questionnaire and screening tools will be administered by trained researchers.
A 30-month community survey will be conducted, and the survey will be divided into three phases, namely study preparation and subject recruitment (6 months), data collection (18 months), and data entry and analysis (6 months).
A survey of 15000 people aged 50 years or older identified in community facilities (e.g., neighbourhood elderly centre, social centre for the elderly) will be conducted. The participants will be invited to their affiliated centres for a brief screening using the FRAIL scale and assessment. A series of community health talks or activities on frailty will be offered to the participants based on the frailty status. Questionnaire and screening tools will be administered by trained researchers.
The primary outcome will be the prevalence of frailty and pre-frailty. Secondary outcomes will cover physical performance measures including hand-grip strength and 5-chair stand test. Anthropometric and demographic data will also be collected using standardized methods and questionnaires respectively.
Views of participants taking part in a community health talks or activities on frailty about what the participants felt or had gained from participating, concerns, and suggestions for change or improvement will be explored by client satisfaction questionnaires.

| Health screening, community health talks or activities on frailty | Behavioral | Screening for frailty using the FRAIL scale to categorize participant's status as robust, prefrail and frail. A series of community health talks or activities on frailty will be provided to each category of participants for the prevention or management of frailty. |
| Measure | Description | Time Frame |
|---|---|---|
| Frailty status | Frailty status (i.e. robust, prefrail or frail) measured using the frailty scale (FRAIL) in which unabbreviated scale name is unavailable for this scale. Frailty scores from 0 to 5 (i.e., 1 point for each component; 0 = best to 5 = worst) and represent robust (0), pre-frail (1-2), and frail (3-5) health status. | 1 day (Once only at screening) |
| Measure | Description | Time Frame |
