Abstract

Nutritional status is an important determinant of overall health and well-being, having a major influence on growth, development, and overall health outcomes. The prevalence of stunting, wasting, and underweight among children in low- and middle-income countries around the world decreased by 29.1%, 6.3%, and 13.7% respectively between 2006 and 2018. For this investigation, PDCA (Plan-Do-Check-Action Method) is used. A total of 165 people participated in a community outreach initiative conducted in March 2024 at an elementary school located in West Java, Indonesia. Early detection of nutritional status is carried out by taking anthropometric measurements. Nutrition during childhood and adolescence is critical for optimal development, growth, and long-term health. Rapid assessment of nutritional status will facilitate timely interventions aimed at preventing disease and reducing premature mortality

Abstract

Caffeine is a commonly consumed stimulant known for its ability to enhance alertness and cognitive performance. One of its most extensively studied effects is its potential to reduce reaction time. However, existing research presents inconsistent findings regarding the effectiveness and duration of caffeine’s impact on cognitive speed.This study aimed to examine the effect of caffeine consumption on reaction time among medical students from the 2022 and 2023 cohorts at the Faculty of Medicine, Universitas Tarumanagara (FK UNTAR). A quasi-experimental design was employed using a comparative pre-test/post-test approach. The sample was selected through non-random consecutive sampling, without stratification. Inclusion criteria included being an academically active student in good physical and mental health.Reaction time was measured using the Ruler Drop Test before caffeine intake, and again at 15 and 30 minutes post-consumption. Data were analyzed using paired t-tests to assess within-group differences and independent t-tests to compare between groups.The results indicated a statistically significant reduction in reaction time following caffeine consumption (p < 0.05). The average reaction time before caffeine intake was 0.202 seconds, decreasing to 0.184 seconds at 15 minutes and 0.163 seconds at 30 minutes post-consumption. These findings suggest that the effect of caffeine on reaction time is most pronounced within 15–30 minutes after ingestion.
