Abstract

Introduction: Cranium capacity can reflect the volume of a person's brain. Brain volume is used to estimate a person's intelligence. Intelligence is a person's ability to learn and to understand something new. Intelligence is governed by the left cerebral cortex. Learning achievement is influenced by level of intelligence. The aim of this study was to prove that the correlation between estimated brain volume and learning achievement. Methods: This research was an observational analytic study with cross-sectional design conducted in Medical Faculty of Sebelas Maret University in October, 2015. Samples from this study were 4th year male students of medical faculty. Sixty nine samples were selected by simple random sampling method. Head height, width and length of the participants were measured to determine the brain volume while exams scores were used as learning achievement indicator. Data analysis was performed using Pearson correlation test. Results: The mean of Estimated brain volume and learning achievement measurement were 1614.35, 105.08 cc and 63.9, 4.48 respectively. The majority of samples (85.5%) had an estimated brain volume more than 1500 cc while 14.5% of samples had an estimated brain volume less than 1500 cc. Most of the samples (89.9%) had satisfactory learning achievement while only 10.1% had a good learning achievement. Data analysis using Pearson correlation test showed p = 0.000 and r= 0.555. Conclusion: There was a positive correlation between estimated brain volume and learning achievement on Medical student of Sebelas Maret. This means that the higher estimated volume of brain, the higher the learning achievement. Keywords: estimated brain volume, learning achievement, medical student

Abstract

Introduction: Hypercholesterolemia refers to condition where levels of cholesterol in theblood are higher than normal reference. In Indonesia, prevalence of hypercholesterolemia are continously increased. Growing evidences indicate there is a relationship between sleep and hypercholesterolemia. The aim of this study was to examine relationship between sleep quality and total cholesterol of geriatric patient. Methods:This study usedobservational analytic method with cross sectional approach. Geriatric patients (n=30) in Geriatric Polyclinic RSUD Dr. Moewardi were recruited in this study used convenience sampling based on inclusion and exclusion criteria.Variables in this study were sleep quality, body mass index (BMI) and total cholesterol. Sleep quality was measure during face to face interviews using validated Pittsburgh Sleep Quality Index Indonesian translation. Total cholesterol was gotten from laboratory test result which was performed a day before. BMI was calculated from direct measurement of weight and height. Data were analyzed by Chi-Square test. BMI as confounding factor was assessed by Mantel-Haenszel. Results:There was a statistically significant positive association between poor sleep quality and total cholesterol of geriatric patients(p=0.029 significance level ? = 0.05). Compared with good sleepers, relative risk (odds ratio) of having cholesterol > 200 mg/dl among poor sleepers was 5.78(95% CI,1.12-29, 85). Conclusions: This study found association between sleep quality and total cholesterol of geriatric patients in RSUD Dr. Moewardi. Keywords: Total cholesterol, sleep quality
