Descrição detalhada
This study is designed to develop and evaluate a sedentary behavior intervention for older adults with coronary heart disease and frailty based on the Integrated Theory of Health Behavior Change (ITHBC). The intervention framework incorporates the three major components of ITHBC: knowledge and beliefs, self-regulation skills and abilities, and social facilitation.
The intervention is intended to improve participants' knowledge and beliefs regarding sedentary behavior and its health consequences, strengthen their motivation and confidence for behavior change, enhance self-regulation skills such as goal setting, self-monitoring, action planning, feedback, and behavioral adjustment, and provide appropriate professional, family, and social support. These strategies are integrated to facilitate the initiation and maintenance of sedentary behavior change.
The study consists of a 1-month structured intervention period followed by a 2-month follow-up period, resulting in a total study duration of 3 months for each participant. Participants in the intervention group will receive the ITHBC-based sedentary behavior intervention according to the study protocol, while participants in the control group will receive the comparator specified in the protocol. The effectiveness of the intervention will be evaluated by comparing changes in sedentary behavior and other prespecified health-related outcomes between the groups during the intervention and follow-up periods.

Experimental: ITHBC-Based Sedentary Behavior Intervention
Participants in this arm will receive a 1-month sedentary behavior intervention based on the Integrated Theory of Health Behavior Change (ITHBC), in addition to usual care.
The intervention incorporates strategies targeting knowledge and beliefs, self-regulation skills and abilities, and social facilitation.
Participants will subsequently be followed for 2 months, resulting in a total study duration of 3 months.
|
The intervention is a 1-month nurse-delivered sedentary behavior intervention based on the Integrated Theory of Health Behavior Change (ITHBC).
It addresses three core components of ITHBC: knowledge and beliefs, self-regulation skills and abilities, and social facilitation.
Intervention strategies include health education related to sedentary behavior and coronary heart disease, individualized goal setting, self-monitoring, action planning, feedback, and professional and family/social support to facilitate reduction of sedentary behavior and promote physical activity.
After the 1-month intervention period, participants will receive a 2-month follow-up to support maintenance of behavior change.
|
|
Sem intervenção: Usual Care
Participants in this arm will receive usual care provided by the clinical team and will not receive the ITHBC-based sedentary behavior intervention.
Participants will be followed for the same 3-month study period as the intervention group.

Prazo |

|
Change in Average Daily Sedentary Time
Prazo: Baseline, Day 8, Month 1, and Month 3
|
Average daily sedentary time will be assessed using the Older Adults Sedentary Behavior Questionnaire.
The questionnaire assesses sedentary behavior during the previous 7 days across seven common sedentary domains, including watching television or videos, using a mobile phone or listening to music or radio, reading, socializing with family or friends, engaging in sedentary hobbies, resting or napping, and other sedentary activities.
Time spent in each domain is reported in 15-minute increments from 0 minutes to 6 hours.
Daily total sedentary time will be derived from the reported sedentary time across the seven domains and expressed as time spent sedentary per day.
Lower values indicate less sedentary time.

Change From Baseline in Longest Continuous Sedentary Bout Duration
Prazo: Baseline, Day 8, Month 1, and Month 3
|
The longest continuous sedentary bout duration will be assessed using the Older Adults Sedentary Behavior Questionnaire.
Participants will report the longest uninterrupted period of sitting, reclining, or lying during the day.
Responses range from 0 minutes to 6 hours in 15-minute increments.
A shorter duration indicates less prolonged sedentary behavior.

Change From Baseline in Frequency of Sedentary Bouts Lasting 30 Minutes or Longer
Prazo: Baseline, Day 8, Month 1, and Month 3
|
The frequency of prolonged sedentary bouts will be assessed using the Older Adults Sedentary Behavior Questionnaire.
Participants will report the number of times per day that they remain sitting, reclining, or lying continuously for 30 minutes or longer.
Response options range from 0 times to 10 or more times per day.
A lower frequency indicates fewer prolonged sedentary bouts.

Change From Baseline in Self-Efficacy to Reduce Sedentary Behavior
Prazo: Baseline, Day 8, Month 1, and Month 3
|
Self-efficacy for reducing sedentary behavior will be assessed using the Chinese version of the Self-Efficacy to Reduce Sedentary Behavior (SRSB) Scale.
The scale contains 9 items, each rated on a 5-point scale from 1 ("not at all confident") to 5 ("very confident").
The total score ranges from 9 to 45, with higher scores indicating greater confidence in reducing sedentary behavior.

Change From Baseline in Fried Frailty Phenotype Score
Prazo: Baseline, Month 1,Month 3
|
Frailty will be assessed using the Fried Frailty Phenotype, which includes five criteria: unintentional weight loss, reduced grip strength, exhaustion, slow walking speed, and low physical activity.
Each criterion contributes 1 point, resulting in a total score ranging from 0 to 5. A score of 0 indicates robust status, 1-2 indicates pre-frailty, and 3-5 indicates frailty.
Higher scores indicate greater frailty.

Change From Baseline in Health-Related Quality of Life Assessed by the SF-36
Prazo: Baseline, Month 1 and Month 3
|
Health-related quality of life will be assessed using the Chinese version of the 36-Item Short Form Health Survey (SF-36).
The instrument contains 36 items covering eight health domains: physical functioning, role limitations due to physical health, bodily pain, general health, vitality, social functioning, role limitations due to emotional problems, and mental health.
Higher scores indicate better health-related quality of life.
