The purpose of this study is to design a nutrition and exercise course for the elderly adults in the community, and to evaluate the effectiveness of this course intervention on the nutritional knowledge, nutritional status, sarcopenia, and health status of the elderly in the community. This study adopted convenience sampling and targeted 108 community elders over 65 years old in Taipei City. All participants receive 3 nutrition and exercise courses. Each course was separated by one week. Measurements and collections were conducted one week before and one week after the course. BMI (body mass index), muscle mass, calf circumference, grip strength, Mini Nutritional Assessment Form Short Form (MNA-SF), SARC-F scale, Taiwan Short Form 36 Health Scale (SF-36) and nutrition knowledge and attitude and behavioral questionnaires will be collected to evaluate the effectiveness of the course.

The elderly population in Taiwan, aged over 65, has exceeded 14%, officially marking the country's transition into an aging society. This demographic shift has brought forth numerous health-related challenges among the elderly, including malnutrition, sarcopenia, and frailty, thereby increasing the risk of falls, cognitive dysfunction, and morbidity rates. This also results in rising disability and mortality rates, ultimately driving up healthcare costs.

The primary aim of this study is to develop a nutrition and exercise program for elderly individuals within the community. This program will be carried out in collaboration with a team of nutrition and exercise professionals. Furthermore, the study seeks to assess the effectiveness of this intervention on the nutritional awareness, nutritional status, sarcopenia, and overall health of elderly community members.

The study employed convenience sampling and included 108 community elders aged over 65 from Taipei City, all of whom were sourced from the community congregated meal stations. Each participant received three nutrition and exercise courses, with each course separated by a week. Measurements for body weight, BMI (body mass index), muscle mass, calf circumference, grip strength, Mini Nutritional Assessment Form Short Form (MNA-SF), SARC-F scale, Taiwan Short Form 36 Health Scale (SF-36), as well as pre- and post-course knowledge, attitude, and behavior assessments were conducted one week before and after the program.

After collecting the questionnaire data, SPSS version 22 (IBM Corp., Armonk, NY, USA) was used for data storage and statistical analysis. A p-value less than 0.05 was considered statistically significant. Descriptive statistical analysis methods, including mean, standard deviation, and percentages, were employed to provide a basic overview of the participant group. To understand differences and correlations between variables, the study utilized Chi-square and Paired Sample T-test methods.

Through this project, the investigators aim to evaluate the impact of the nutrition and exercise course intervention for elderly individuals in Taipei City. This endeavor will empower participants to incorporate nutrition and exercise strategies into daily lives, ultimately fostering better health outcomes for the elderly adults.
