<![CDATA[Background: Stunting remains a major public health concern in Aceh, Indonesia. Posyandu cadres play an important role in monitoring child growth and identifying early signs of nutritional problems. However, manual recording systems and inconsistent anthropocentric measurement practices may limit the accuracy and effectiveness of growth monitoring. Digital health innovations combined with standardized training may help address these challenges. Objective: This study aimed to analyze the effect of the AA-PoDiTa (Digital Posyandu for Infants and Toddlers) application combined with WHO-standard anthropocentric training on Posyandu cadres’ knowledge and practical skills. Methods: A quantitative pre-experimental study with a one-group pretest and post-test design was conducted among 20 active Posyandu cadres in Gampong Blang Teue, Lhokseumawe, Indonesia. Participants were selected using total sampling. The intervention consisted of eight training sessions conducted over six months (April–September 2026). Knowledge was assessed using a structured questionnaire, while practical skills were evaluated using an observation checklist. Data were analyzed using the Shapiro–Wilk test and Wilcoxon signed-rank test. Results: The mean knowledge score increased from 55.00 at pretest to 86.20 at post-test. Similarly, the mean practical skill score improved from 53.60 to 87.60. Both improvements were statistically significant (p < 0.001), with large effect sizes (r ≈ 0.88). All participants demonstrated improvements in their knowledge and practical skills following the intervention. Conclusion: The combination of the AA-PoDiTa application and WHO-standard anthropocentric training significantly improved Posyandu cadres’ knowledge and practical skills. This integrated approach offers a promising strategy for strengthening community-based growth monitoring, supporting Posyandu digitalization, and improving stunting prevention efforts.]]>
