<![CDATA[To compare the effect of "CEMAS" (Cegah Malnutrisi dengan Aksi Sehat / Preventing Malnutrition with Healthy Action) nutrition education delivered through a facilitated PowerPoint presentation versus a printed leaflet on maternal knowledge and self-reported parenting practices. In a two-group pretest posttest quasi-experimental study, 60 mothers of stunted children aged 6 59 months were randomly sampled from the eligible register of a primary health centre catchment area in South Balikpapan District and allocated by service schedule to a PowerPoint group (n = 30) or a leaflet group (n = 30); individual random assignment was not performed. Each group received a single 30 60 minute CEMAS session. Within-group change was tested with paired t-tests and between-group difference in change with independent-samples t-tests, with an analysis of covariance adjusting for baseline score as a supporting analysis. Knowledge and parenting-practice scores rose in both groups (all p < 0.001). The mean pre-to-post change was larger in the PowerPoint group for knowledge (8.30 versus 5.00 points) and for parenting practice (12.43 versus 4.30 points). Post-intervention scores also favoured PowerPoint for knowledge (mean difference 5.13; 95% CI 3.94 to 6.32; p < 0.001; Cohen's d = 2.23) and for parenting practice (mean difference 5.83; 95% CI 4.70 to 6.96; p < 0.001; Cohen's d = 2.67). Baseline scores differed between groups, so these estimates are not adjusted for the starting point unless stated. CEMAS-based nutrition education improved maternal knowledge and self-reported parenting practices under both delivery formats, with larger gains under the PowerPoint format. Because allocation was not random, follow-up was short and no anthropometric outcome was measured, any effect on child linear growth remains unestablished and requires confirmation in controlled studies.]]>
