Summary
Global suicide mortality rates declined overall between 2000-2019, but increased in the Americas and specific countries. Further research is needed to understand and address these unfavorable suicide mortality trends.
Area of Science:
- Global Health
- Epidemiology
- Public Health
Background:
- Limited studies exist on global suicide mortality.
- Previous evaluations often focused on specific populations.
Purpose of the Study:
- To analyze global, regional, and national suicide mortality trends from 2000 to 2019.
Main Methods:
- Utilized World Health Organization and Global Burden of Disease Study mortality data.
- Calculated age-standardized rates (ASRs) per 100,000 population.
- Employed joinpoint regression analysis to determine average annual percent change (AAPC).
Main Results:
- In 2019, 759,028 suicide deaths occurred globally (523,883 male, 235,145 female).
- Global suicide mortality ASR was 9.0/100,000, with Africa having the highest rates (11.2) and Eastern Mediterranean the lowest (6.4).
- Globally, suicide mortality ASR decreased by 2.4% annually (2000-2019), but increased in the Americas. Barbados, Grenada, Serbia, and Venezuela showed the most significant declines, while Lesotho, Cyprus, and Paraguay showed notable increases.
Conclusions:
- Most countries experienced decreasing suicide mortality trends.
- A concerning increase in suicide mortality was observed in specific populations.
- Further research is recommended to investigate reasons for unfavorable trends and enhance suicide prevention efforts.

01:52Regression Toward the Mean
6.4K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

105
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...

01:14Parametric Survival Analysis: Weibull and Exponential Methods
550
Parametric survival analysis models survival data by assuming a specific probability distribution for the time until an event occurs. The Weibull and exponential distributions are two of the most commonly used methods in this context, due to their versatility and relatively straightforward application.
Weibull Distribution
The Weibull distribution is a flexible model used in parametric survival analysis. It can handle both increasing and decreasing hazard rates, depending on its shape parameter...

01:20Comparing the Survival Analysis of Two or More Groups
256
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

01:15Assumptions of Survival Analysis
175
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
