Abstract

The growing elderly population in Indonesia is accompanied by a high risk of sarcopenia due to inadequate protein and vitamin D intake, as well as low nutritional knowledge. This study aimed to analyze the effect of educational media (hand-fan poster, WhatsApp video, and booklet) on increasing knowledge and attitudes (protein and vitamin D intake) among elderly women for sarcopenia prevention. A quasi-experimental pre-test and post-test control group design was conducted involving 30 elderly women in Tambun Selatan District, divided into three intervention groups (n = 10$). The 7-day intervention evaluated knowledge using a structured questionnaire and attitude through 2x24-hour dietary recall to assess protein (%RDA) and vitamin D adequacy. Data were analyzed using paired sample t-test and Wilcoxon signed-rank test. Results showed that all three media significantly increased elderly knowledge: hand-fan poster (p<0.05), WhatsApp video (p<0.05), and booklet (p<0.05), with the booklet yielding the highest improvement. Regarding attitude, a significant increase in protein intake adequacy occurred only in the hand-fan poster group (p<0.05), whereas WhatsApp video (p>0.05) and booklet (p>0.05) showed no significant effect. Significant improvements in vitamin D intake adequacy were found in both the hand-fan poster (p<0.05) and booklet groups (p<0.05), while WhatsApp video was not significant (p>0.05). In conclusion, nutrition education effectively improves knowledge among elderly women, but functional printed media such as hand-fan posters are more consistent in driving behavior and attitude changes in daily nutrient intake compared to digital media.
