Exploring Mortality Rates for Major Causes of Death in Korea

Abstract

Background:The trends and patterns of the mortality rates for causes of death are meaningful information. They can provide a basis for national demographic and health care policies by identifying the number, causes, and geographical distribution of deaths.Objective:To explore and analyze the characteristics of the mortality rates for major causes of death in Korea.Methods:Some common data analysis methods were used to describe the data. We also used some visualization techniques such as heat maps and line plots to present mortality rates by gender, age, and year.Results:Our analysis shows the crude mortality rates have continually decreased over the last 25 years from 1983, though they have increased slightly since 2006. In addition, the top eight causes of death accounted for 80% of all Korean deaths in 2015. During the period 2005-2015, the leading cause of death was cancer in male and circulatory diseases in female. The trend for respiratory diseases shows a steep upward trend in males, while a similar trend can be observed for respiratory and nervous system diseases in females.Conclusion:The deaths for circulatory, respiratory, nervous system, digestive, and infectious diseases are the highest in the age 80 to 84, while cancer is the leading cause of death for ages 75 to 79. In addition, the mortality rates for circulatory, nervous, and respiratory diseases increase rapidly after the age of 80. Therefore, policies on health and welfare for the elderly are getting more and more important.

Prediction of the Mortality Risk in Peritoneal Dialysis Patients using Machine Learning Models: A Nation-wide Prospective Cohort in Korea

“…Data source and study patients. We conducted our analyses with data obtained from the database in consents every end-of-year in study observation 46 . In our study patients' , a total of 156 patients were dropped out for kidney transplantation, and censored.…”

Low‐density lipoprotein cholesterol reduction and target achievement after switching from statin monotherapy to statin/ezetimibe combination therapy: Real‐world evidence

“…Atherosclerotic cardiovascular disease, including ischaemic heart disease, cerebrovascular disease and atherosclerosis, is the second most common cause of death, after neoplasms, 1 with a mortality in 2017, of 119.6 per 1 000 000 persons 2 . Dyslipidaemia, characterized by high levels of low‐density lipoprotein cholesterol (LDL‐C), is a well‐established major risk factor for atherosclerotic disease 3 .…”

Low serum total CO2 and its association with mortality in patients being followed up in the nephrology outpatients clinic

“…The primary outcome was to clarify the all-cause mortality according to the TCO 2 level, and the secondary outcome was to find a new development of ESRD that required dialysis and progression to mortality from various causes. We obtained mortality information from the national statistics office 17 , and ESRD incidence was defined as follows: patients recently undergoing hemodialysis were extracted from the electronic medical records using the clinical data warehouse in our study centers. Patients who had started hemodialysis therapy were identified by the combination of operational definitions as follows: the occurrence of a new claim for the payment code of hemodialysis by screening ICD-10 codes, and vascular access operations; incident dialysis was also identified by the first date of when dialysis was suggested.…”
