Effects of Adolescents' Lifestyle Habits and Body Composition on Bone Mineral Density.

The incidence of osteoporosis is increasing as the population ages, as is the need to manage and prevent it. Adolescence is the period when the fastest development of bone mass takes place. Increasing adolescents' maximum bone mass and avoiding the risk factors for its loss are effective for preventing osteoporosis. This study investigated the factors influencing adolescents' bone mineral density (BMD). The participants were 126 middle- and high-school students from Gangwon-do; 47.6% (n = 60) were male, with an average age of 15 (range 12-18) years of age. It was found that age, carbonated beverages, snacks, and calcium supplements were variables that showed significant differences in adolescents' BMD. Additionally, through correlation analysis, it was found that height, weight, body mass index (BMI), body water, protein, minerals, body fat mass, and skeletal muscle mass were correlated with BMD. Multiple regression analysis identified age, calcium supplements, BMI, body fat mass, and skeletal muscle mass as BMD-associated factors. These results show that adolescents' BMD is higher with lower body fat mass, higher BMI and skeletal muscle mass, and a higher intake of calcium supplements.

Development of video-based educational materials for kidney-transplant patients.

INTRODUCTION: Treatment adherence has been evaluated as a major predictor of long-term outcome, and education has been suggested to improve adherence. Considering the characteristics of adult learners, it is necessary to implement educational programs that meet the needs of transplant patients. Multimedia education may be well-suited for this. This study aims to develop video education materials in accordance with transplant patients' self-care needs. METHODS: This study includes a literature review and patient interviews aimed at developing video education materials for the self-care needs of patients who underwent renal transplant surgery at a university hospital in Seoul. Ten patients were interviewed about the desired educational content, accessibility, and other preferences. After verifying the validity of the data, the video scenarios were produced and satisfaction surveys were conducted. RESULTS: Eleven self-care education items were identified through interviews with 10 kidney transplant patients. The expert validation of video-based educational content result was high (mean CVI = 0.94). The mean score of the patients' satisfaction evaluation of the completed 7-minute video instructional materials was also high (4.55 on a 5-point Likert scale). CONCLUSION: Findings indicate that the video education materials will meet the needs of adult learners and mitigate the limitations of the existing education programs by increasing interest and motivation and may contribute to increased treatment adherence and ultimately, positively effect self-care for new transplant patients.
