Self-Management Support for Lung Cancer Patients With Cachexia

Feasibility of the self-management support program

Assessed by recruitment rate (percentage of eligible patients enrolled), retention rate (percentage of participants completing the 12-week study), and adherence to the wearable device and Line@ interaction.

Time frame: Week 12

Change from balseline in Body Mass Index(BMI)

BMI is calculated as weight in kilograms divided by the square of height in meters (kg/m\^2), measured using Bioelectrical Impedance Analysis (BIA) with the InBodyDial H20 device. Data are recorded and rounded to one decimal place.

Time frame: Baseline, Week 8, Week 12

Change from baseline in skeletal muscle mass

Measured using Bioelectrical Impedance Analysis (BIA) with the InBodyDial H20 device. Data are recorded in percentage (%) and rounded to one decimal place.

Time frame: Baseline, Week 8, Week 12

Change from basleline body fat mass at 12weeks

The body fat mass will be detected by InBodyDial H20. Data record with percentage and after the first decimal place.

Time frame: Baseline, Week 8, Week 12

Change from Baseline in Upper Body Muscle Endurance (30-Second Arm Curl Test)

Used to evaluate upper body muscle endurance. The participant sits on a chair with back supported and performs as many bicep curls as possible in 30 seconds using a dumbbell (5 lbs for females; 8 lbs for males). The total number of completed curls is recorded. Higher scores (more repetitions) indicate better upper body muscle endurance.

Time frame: Baseline, Week 8, Week 12

Change from Baseline in Lower Body Muscle Strength (30-Second Chair-Stand Test)

Used to evaluate lower body muscle strength. The participant sits in the middle of a chair with back straight and feet flat on the floor, then stands up completely and sits down repeatedly for 30 seconds. The total number of completed stands is recorded. Higher scores (more repetitions) indicate better lower body muscle strength.

Time frame: Baseline, Week 8, Week 12

Change from Baseline in cardiopulmonary function (6-Minute Walk Test)

Examine cardiopulmonary function in this study. Let the participant sit and rest 10 minutes before test. Check vital signs and oxygen situation for patient safety. Position the participant at the starting line, and walking back and forth along the mark on the floor. When the participant starts to walk, starts the times. Don't walk nor talk with him/ her, and count the laps attentively. Participant can walk longer distance means better cardiopulmonary function.

Time frame: Baseline, Week 8, Week 12

Change from basline in quality of life (FACT-L)

The Functional Assessment of Cancer Therapy-Lung (FACT-L) is used to determine quality of life in lung cancer patients. It contains 5 dimensions: physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), functional well-being (7 items), and lung cancer subscale (9 items). Items are rated on a 5-point Likert scale with total scores ranging from 0 to 144. Higher scores indicate better quality of life."

Time frame: Baseline, Week 12

Change from Baseline in Cancer anorexia-cachexia syndrome nutrition knowledge (CACSNKQ)

The CACSNKQ is designed to assess patients' knowledge regarding cancer anorexia-cachexia syndrome. All items are multiple-choice with one correct answer. The total score ranges from 0 to 21, with higher scores indicating better nutritional knowledge and self-management ability against the syndrome.

Time frame: Baseline, Week 12

Change from baseline in dietary intake (24 hours dietary recall)

To assess participants' nutritional intake. A 24-hour dietary recall interview is conducted to record all food and beverage consumption (including dish names, portion sizes, and preparation methods). Data are converted into total calories (kcal) and macronutrients (protein, fat, and carbohydrates in grams) by a registered dietitian using nutritional analysis software.

Time frame: Baseline, Week 8, Week12

Change from Baseline in amount of exercise

Measured using the Xiaomi Smart Band and a self-management support manual. The Xiaomi Smart Band is worn daily by participants to record continuous physical activity data, including daily step count, exercise duration, walking distance, and heart rate. Additionally, participants use the self-management support manual to log the specific duration and frequency of resistance training and stretching exercises.

Time frame: Baseline to Week 8, and Week 8 to Week 12
