Suicide Death Rate after Disasters: A Meta-Analysis Study
Summary
Suicide death rates significantly increased globally after disasters, particularly in men. This highlights the critical need for post-disaster mental health support to prevent suicide.
Area of Science:
- Public Health
- Epidemiology
- Mental Health Research
Background:
- Disasters negatively impact individual health, leading to psychosocial disorders and potential suicide.
- Quantifying suicide death rates post-disaster is crucial for understanding public health implications.
Purpose of the Study:
- To measure the global rate of suicide deaths following various types of disasters.
- To analyze trends in suicide mortality in relation to disaster events.
Main Methods:
- A comprehensive meta-analysis of English-language studies published up to 2019.
- Data sourced from major electronic databases including PubMed, Web of Science, and Google Scholar.
- Statistical analysis using fixed- and random-effects models in STATA, including meta-regression and Cochrane tests.
Main Results:
- Eleven studies with 65,495,867 participants were analyzed.
- Global suicide death rates increased from 13.61 to 16.68 per population.
- Significant increases were observed in men (28.36 to 32.17), but not in women (12.71 to 12.69).
Conclusions:
- Disasters are associated with a significant rise in suicide death rates, underscoring their detrimental effect on population health.
- Implementing targeted supportive and interventional measures post-disaster is essential for suicide prevention efforts.

Hazard Rate
322
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...

Actuarial Approach
223
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.

Censoring Survival Data
425
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Assumptions of Survival Analysis
302
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.

Introduction To Survival Analysis
621
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.

Hazard Ratio
456
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.
