Summary
China's life expectancy increased by 9.44 years to 76.3 years by 2016. Reductions in infant mortality and later increases in cardiovascular diseases, chronic respiratory diseases, and neoplasms drove this gain.
Area of Science:
- Public Health
- Demography
- Epidemiology
Background:
- Achieving "Healthy China 2030" requires health policies informed by evolving mortality patterns.
- Understanding temporal trends in life expectancy (LE) and its determinants is crucial for effective policy development.
Purpose of the Study:
- To investigate the temporal patterns of life expectancy (LE) in China from 1990 to 2016.
- To analyze the age- and cause-specific contributions to changes in LE over this period.
Main Methods:
- Utilized the Joinpoint regression model.
- Employed Arriaga's decomposition method to analyze LE contributions.
Main Results:
- China's LE increased by 9.44 years to 76.3 years by 2016.
- Infant mortality reduction significantly boosted LE (1.27 years) from 1990-2002, primarily due to infectious diseases.
- Post-2002, LE gains were mainly driven by non-communicable diseases (cardiovascular, chronic respiratory, neoplasms) in the elderly, with changing impacts from injuries.
Conclusions:
- Cardiovascular diseases, chronic respiratory diseases, and neoplasms are key drivers of increased LE, particularly in males and the elderly.
- Health policies should focus on these non-communicable diseases to further enhance life expectancy in China.

430
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...

01:22Applications of Life Tables
270
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

02:20Longitudinal Research
13.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

00:57Population Growth
27.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

3.5K
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...
