BACKGROUND: There are currently few appropriate instruments for assessing nutrition care competencies in clinical practice. This study aimed to develop a perceived nutrition care competencies (PNCC) scale for dietetic students and test its validity. Factors that influence PNCC scores were examined through a cross-sectional study. METHODOLOGY: This cross-sectional survey involved 501 dietetic students (mean age of 21.4 years, 428 females) and employed a web-based questionnaire between September 2022 and February 2023. A scale derived from previous research was used to assess nutrition management practices and basic dietetic competencies. Questionnaire data were analysed using exploratory factor analysis. RESULTS: Exploratory factor analysis identified five factors: nutritional status assessment and preparation for intervention, communication skills for nutritional support, nutritional diagnosis and recording, supplementation suggestions and coordination and dietitian orientation and attitude. Multivariate logistic regression analysis showed that field practice increased the 'nutrition diagnosis and recording' scores, and the subconcepts 'nutrition diagnosis and recording' and 'suggestion and coordination of nutritional supplementation' showed odds ratios (ORs) <1 for the 'online role-play among students' experience. In addition, experience with face-to-face simulated patients increased the total scores (OR 2.46, 95% confidence interval 1.43-4.22, p = 0.001). CONCLUSIONS: The PNCC scale demonstrated reliability and validity, offering a valuable measure of dietetics students' perceptions of their nutrition care practice competence. The findings highlight the need to increase the willingness of the students to work as dietitians and to incorporate realistic, safe learning experiences beyond on-site practice to enhance nutrition management practice competency.

PURPOSE: Electromyostimulation (EMS) induces a short-term change in muscle metabolism, and EMS training induces long-term improvements of muscle atrophy and function. However, the effects of EMS training on intramuscular fat in older adults are still poorly known. The purpose of this study was to examine whether the intramuscular fat index and biochemical parameters change with EMS training of the quadriceps femoris muscles in older adults. METHODS: Nineteen non-obese older men and women performed EMS training of the quadriceps femoris for 12 weeks (3 times/week; single session for 30 min). The intramuscular fat content index was estimated by echo intensity of the vastus lateralis and rectus femoris muscles on ultrasonography, and muscle thickness was also measured. Muscle strength was assessed as the maximal voluntary contraction during isometric knee extension. Echo intensity, muscle thickness, and muscle strength were measured before and after EMS training. A rested/fasting blood samples were collected before and after EMS training for measuring plasma glucose, insulin, free fatty acid, triglyceride, and interleukin-6 concentrations. To examine the acute effect of a single-EMS session on biochemical parameters, blood samples were taken before and after the EMS session. RESULTS: EMS training did not significantly change echo intensity in muscles, muscle thickness, muscle strength, or biochemical parameters. Regarding the acute effect on blood lipid concentrations, a single-EMS session increased free fatty acid and glucose concentrations. CONCLUSION: EMS sessions had an acute effect of increasing free fatty acid and glucose concentrations, but EMS training intervention did not improve intramuscular fat content.
