The purpose of this study is to measure the changes in life expectancy at birth caused by the changes at older ages(age 65 and over) in patterns of mortality In Korea during the last decades. This study used data on the life tables(1990-2008) and the annual report on the cause of death statistics(2000-2008) released by the National Statistical Office Republic of Korea. The contribution of different ages, sexes and causes of death to the change in life expectancy at birth during the 1990-2008 was estimated with a decomposition technique developed by Arriaga. During the last decades, life expectancy of the elderly population has increased in Korea. The mortality change at the age 65 and over had the largest impact on the life expectancy at birth during the 1990-2008, contributing in both sexes with 2.98(32.22%; males) and 4.12(52.96%; females) years respectively, and has increased since 1990. The impact of the sex mortality differential at ages 70-74 years in 2008 was larger than the total sex differential of life expectancy at birth in 1990, 1995, 2000, 2005 and 2008. In 2000-2008, mortality reduction of cerebrovascular diseases(0.49; male, 0.71; female) at age groups(over 65 age) made the largest contribution of life years to all groups of causes to any age groups. While an increase In mortality from respiratory tuberculosis, malignant neoplasm of stomach, malignant neoplasm of lung, heart diseases, pneumonia, chronic lower respiratory diseases and diseases of liver tended to reduce life expectancy. Accordingly the improvement of the mortality of elderly people will contribute largely to the increase in life expectancy.

The purpose of this study was to measure the changes in life expectancy at birth caused by the changes in patterns of mortality in korea during last decades. This study used data on the life tables (2000-2013) released by the National Statistical Office Republic of Korea. The contribution of age, sex and cause of death to the change in life expectancy at birth during the 2000-2013 was estimated with a decomposition technique developed by Arriaga``s method. During the last decade, life expectancy of the elderly population has increased in Korea. The mortality changes at the age 65 and over had the largest impact on the life expectancy at during the 2000-2013, contributing in both sexes with 2.757 years (44.0%; male) and 3.780 years (69.3%; female) respectively, and have increased since 2000. During 2000-2013, the sex mortality differential life expectancy at birth aged 75-79 years contributed the most to the total sex differential of life expectancy at birth, and the sex differential at the older ages contributed to the increase in the total sex differential of life expectancy at birth. During the periods, mortality increases from cerebrovascular disease, and malignant neoplasm were the largest contributor of years of life. And mortality reduction of cerebrovascular diseases (0.74 in male, 1.04 in female) at age groups (aged 65 years) made the largest contribution of life years to all groups of causes to any age groups.

Objectives: To compare contribution of age distribution and age specific death rates to intentional self-harm (ISH) between 1985-89 and 2010-14. Methods: We used 1985-89 (16,977 deaths) and 2010-14 (73,883 deaths) ISH death data of Korea Statistics. We decomposed the contributions of age-specific ISH death rates and age distribution of population (Kitagawa`s decomposition method) to overall increment of ISH death rates during the period. Odds ratio (OR) and 95% confidence intervals were calculated to describe the secular trend of ISH death rates by age groups. Results: Between 1985-89 and 2010-14, ISH death rates (per 100,000 persons) increased from 8.16 to 29.57 (OR: 3.62, 95% confidence interval: 3.56-3.86). ISH death rates increased from 11.74 to 40.45 in male (OR: 3.44) and increased from 4.53 to 18.66 in female (OR: 4.12). ISH death rates have risen with advancing age, peaking at 60 years & older in both gender. In 1985-2014, a prominent increase in ISH death rates occurred among those aged 60 years and older (3.82 times in male, and 4.28 times in female), and followed by the group of 40-59 years (2.81 times in male, and 3.54 times in female). Most (59.6 percent) of the overall increase in the ISH death rates was attributable to male age group of 40-59 years and 60 years & older, and 25.3 percent of the overall increase of death rates was attributable to female age group of 40 years & older. Conclusions: The remainder of the total increment in the ISH death rates during the period was explained by increase the proportion and the excessive death rates of male age group of 40-59 years and 60 years & older. There was a need to close attention in male age group of 40 years & older to reduce ISH death rates and understand the contributing factors to ISH death.

Objectives: To determine the contribution of specific age groups and causes of death contributing to the changes in the Korea-Japan life expectancy gap from 2000-2019. Methods: Standard life table techniques were used decompose the change in the Korea-Japan life expectancy gap by combing absolute changes in age-specific mortality with relative changes in the distribution of causes of death. Results: Among males, the Korea-Japan life expectancy gap increased 4.2 years in the period 2000-2019. The decline in the life expectancy gap was lager among males, declining by 21.53% (5.289 to 1.139). Nearly all of the 2.07-year decline among males was due to relative mortality improvement among korea at ages 65 to 74 years. primarily due to increased mortality from malignant neoplasms. The gap among females increased by 3.8 years in the period 2000-2019, primarily due to increased mortality from cerebrobascular disease. The decline in the life expectancy gap was larger among males at older ages. Conclusions: The Korea-Japan life expectancy gap has declined because of relative mortality improvements in malignant neoplasms and cerebrobascular diseases. Further narrowing of the gap will require concerted efforts in public health and health care to address the major causes of th remaining gap from malignant neoplasms, cerebrobascular diseases, hypertension diseases.

The objective of this study is to observe the method of delivery by analyzing the data of National Health Insurance Service (2003-2012; 4,098,432 singleton birth, excluding medical benefits). The rate of single spontaneous delivery (SSD) decreased by more than 2 percent in 2012(53.4 percent) compared with in 2006-2011 (54.4-54.8 percent). The caesarean section (CS) rate decreased nearly 4 percent from 2003 (36.0 percent) to 2011 (34.5 percent), but for the most recent 2-year of 2011-2012, the rate of CS increased from 34.5 percent to 35.6 percent. The urilization rate of forceps and vacuum extractor (FVE) decreased from 6.1 percent to 5.5 percent during 2003-2012. CS rete increased with advancing maternal age(≤ 24 yeats, 26 percent; ≥40 years, 61.1 percenys) while SSD rate decreased (≤ 24 years, 61.2 percent; ≥ 40years, 32.4 percents). The rate of FVE use and breech extraction decreased with maternal age. The odds ratio of CS in age group ≤ 24, 30-34, 35-39 and ≥ 40 years were 0.85 (95% confidence interval: 0.84-0.86), 1.19 (1.19-1.20), 1.57 (1.56-1.58).2.00(1.99-20.1). respectively. Compared with rete of CS for 25-29 age group. The odds ration of SSD comparing 25-29 years old were 1.07(1.06-1.07) for aged ≤24 years, 0.93 (0.93-0.93) for 30-34 years, 0.77 (1.76-0.77)for 35-39 years and 0.56(0.55-0.57) for aged ≥40 years.

The purpose of this study is to measure the changes in life expectancy at birth caused by the changes in patterns of mortality in Korea during the last decades. This study used data on the life tables (1975-2005) and the annual report on the cause of death statistics (1995-2005) released by the National Statistical Office Republic of Korea. The contribution of different ages, sexes and causes of death to the change in life expectancy at birth during the 1975-2005 was estimated with a decomposition technique developed by Arriaga. The mortality change of age 65+ had the largest impact on life expectancy at birth during the 1995-2005. And the contribution of life expectancy at birth in age groups of over 65 years was more increased than any other age groups did, furthermore, this trend of females was even more remarkable. During 1975-2005, the sex mortality differential life expectancy at birth at ages 55-64 years contributed the most to the total sex differential of life expectancy at birth. Particularly in 2005, the sex moratality differential at the oldest ages contributed to the increase in the total sex differential of life expectancy at birth. In 1995-2005 periods, mortality reduction from hypertensive diseases was the largest contributor of years of life in both periods, Especially, the mortallity increases of transport accidents, cerebrovascular diseases, malignant neoplasm of trachea, bronchus and lung, malignant neoplasm of liver and intrahepatic bile ducts was the contributor of years of life during that first period. And mortality reduction of hypertensive diseases (0.65; male, 0.34; female) at age groups (over 65 age) made the largest contribution of life years to all groups of causes to any age groups.

Objectives: The objective of the study was to analyze the weekly variation of deaths from intentional self-harm by hanging, strangulation and suffocation (HSS: KCD-6 code, X70). Methods: There were 44,794 HSS deaths from the death certificate data (2010-15) of Korea Statistics. For analyzing weekly pattern of HSS deaths, we used the average number of daily HSS deaths and the index of death occurrence (IDO). IDO was calculated as a ratio of the average number of HSS deaths per day of the week to the average number of HSS deaths per day during 6 years. Results: Through 2010-15, the HSS death rate (per 100,000) decreased from 22.1 to 16.3. The HSS death rate was 27.0 in male and 11.1 in female. The HSS death rate by age was 13.0 in aged 20-39 years, 19.4 in aged 40-59 years, and 28.6 in aged 60 years and older. The average number of HSS deaths per day was 20.4 deaths during the period. The daily average of HSS deaths was lower at weekends and holidays than that of weekdays, they have become more concentrated on Monday. On Saturday (17.9 deaths, IDO: 88), the number of HSS death per day was the lowest, and Monday (23.4 deaths, IDO: 115) was the highest. The daily HSS deaths was less likely to occur on holidays (18.0 deaths, IDO: 88). In both gender, all age group and all seasons, the pattern of daily HSS deaths were more prevalent on Monday and were less likely to occur on Saturday, Sunday and holidays. The variations of daily HSS deaths in consecutive holidays (lunar new year’s day and Korean thanksgiving day) showed wide fluctuation from a trough deaths (a holiday) to a peak deaths (after a holiday). The daily HSS deaths 4 days after a holiday increased I.5 times in both gender as compared with daily HSS deaths of a holiday. The daily HSS deaths during 4 days after a holiday increased 1.4 times in aged 40-59 years, and 1.9 times in aged 60 years and older than that of a holiday. Conclusions: The daily HSS deaths were more prevalent on Monday and were less likely to occur on Saturday and public holidays. The daily HSS deaths among aged 40-59 and ≥60 years increased in the week after consecutive holidays.

To figure our the contribution of maternal age to multiple birth tate, we analyzed the birth certificated data of 1,901,505 births in 1997-99 and 1,359,908 births in 2011-13 among married women. We decomposed the contributions of age-specific multiple birth rate and maternal age distribution (Kitagawa``s decomposition method) to overall multiple birth rates during the periods. Between 1997-99 and 2011-13, multiple birth rates among women increased from 1.50 percent to 3.27 percent (odds ratio: 2.18, 95% confidence interval: 2.14-2.21). Multiple birth rates have risen with advancing maternal age, peaking at 35-39 years (2.58 percent in 1997-99, and 4.63 percent in 2011-13) and declining thereafter. Multiple birth rates greatly increased for women aged 30-34 years (odds ratio: 1.83), during the period. The rates increased 1.79 (OR) for women aged 35-39, followed by women aged 40 years and older (OR: 1.71), aged 25-29 0.70), and aged 20-24 (1.32). Most (73.2%) of the overall increase in the multiple birth rates was attributable ro the increase in the proportion of women aged 30-34 years, and 35.5 percent for women aged 35-39 years. There was a need to more research in this area to understand the contributing maternal age factors ro multiple birth rates.
