[Injury mortality among Chinese aged 5 to 24 years from 1990 to 2019].
Summary
Injury mortality in Chinese children and adolescents (ages 5-24) significantly decreased from 1990-2019. Road injuries became the leading cause of death, surpassing drowning, with self-harm also a major concern.
Area of Science:
- Public Health
- Epidemiology
- Injury Prevention
Background:
- Injury remains a significant cause of mortality among children and adolescents globally.
- Understanding temporal trends and risk factors for injury mortality is crucial for effective public health interventions.
- China has experienced rapid socioeconomic changes, potentially impacting injury patterns in young populations.
Purpose of the Study:
- To analyze trends in injury mortality among Chinese children and adolescents (ages 5-24) from 1990 to 2019.
- To identify the leading causes of injury death and their changes over three decades.
- To provide a basis for developing targeted injury prevention policies.
Main Methods:
- Utilized Global Burden of Disease (GBD) 2019 data for mortality statistics in China (1990-2019).
- Described changes in overall injury mortality and specific causes (road injuries, drowning, self-harm).
- Applied Age-Period-Cohort (APC) analysis to assess age, period, and cohort effects on mortality risks.
Main Results:
- Overall injury mortality for ages 5-24 in China decreased from 46.22 to 20.36 per 100,000 between 1990 and 2019.
- Road injuries replaced drowning as the leading cause of injury death; self-harm emerged as the third leading cause.
- APC analysis indicated decreasing risks for road injuries, drowning, and self-harm with period and cohort, but age-related U-shaped trends for road injuries and increasing trends for self-harm.
Conclusions:
- Significant reduction in injury mortality among Chinese youth over 30 years.
- Distinct patterns in cause-specific injury deaths across different subgroups (gender, age).
- Need for targeted policies addressing specific injury types and demographic vulnerabilities to further reduce mortality.

188
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,...

119
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...

01:11Hazard Rate
184
The hazard rate, also known as the hazard function or failure rate, is a statistical measure used to describe the instantaneous rate at which an event occurs, given that the event has not yet happened. From a probabilistic perspective, it represents the likelihood that a subject will experience the event in a very small time interval, conditional on surviving up to the beginning of that interval. In terms of frequency, the hazard rate can be viewed as the ratio of the number of events to the...

The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

334
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
