Development of hypertension is more potentially associated with the more progressive NAFLD than normal or milder state. In addition, NAFLD was an independent risk factor for hypertension.

Elevation of serum ferritin level is significantly associated with NAFLD and blood ALT elevation in Korean general population.

The aim of this study was to assess the secular growth changes in Korean children and adolescents during the last four decades. In 2005, 68,790 boys and 62,557 girls were recruited for this study across the nation in 2005. Anthropometric data (weight, height, etc.) were measured. We compared the results of previous nationwide growth studies with this study. The results of this survey indicate that the growth and developmental status of Korean children and adolescents has been changed substantially compared with those in 1965, 1975, 1984, and 1997. The data presented in this study show a distinct secular increase in growth in body height and weight of Korean children and adolescents spanning this period. A nationwide survey every 5 years would be beneficial to establish a reference standard for the growth of children and adolescents according to the socioeconomic, environmental, and nutritional changes.

There have been many studies between serum uric acid (UA) and chronic kidney disease (CKD). However, as far as we know, little research has been done to examine the prospective association between serum UA and development of CKD in Korean men. This prospective cohort study was performed using 18,778 men who participated in a health checkup program both on January, 2005 and on December, 2009. CKD was defined as an estimated glomerular filtration rate < 60 mL/min per 1.73 m2. The odds ratio (OR) from binary logistic regressions for the development of CKD was determined with respect to the quintiles grouping based on serum UA. During 74,821.4 person-years of follow-up, 110 men were found to develop CKD. The OR for the development of CKD increased as the quintiles for baseline serum UA levels increased from the first to fifth quintiles (1.00 vs 1.22, 1.19, 2.59, and 3.03, respectively, p for linear trend < 0.001) after adjusting for covariates. The adjusted OR comparing those participants with hyperuricemia ( ≥ 7.0 mg/dL) to those with normouricemia ( < 7.0 mg/dL) was 1.96 (1.28-2.99). Elevated serum UA levels were independently associated with increased likelihood for the development of CKD in Korean men (IRB number: KBC10034).
