Years of Life Lost due to Suicide in Southern Iran 2011–18: A Population–Based Study

Abstract

Background: Suicide is a major public health concern with diversity in epidemiological aspects and applied methods. In this study, we estimate years of life lost (YLLs) related to completed suicidal in the Fars province, southern Iran. Methods: Our study included data of all mortality events during 2011-2018 from Fars Suicide Surveillance System (FSSS). The validity of qualitative and quantitative variables was assessed through contrasting data between different sources and phone call justification. Case-fatality rates, age-specific and gender-specific mortality rates, ASR (age standardized rate), and YLLs through WHO’s 2015 "YLL template" were calculated. Results: During the study period, 2384 mortalities with a mean age of 32.73±15.65 had been registered. Most of them were males (male: 70.05% vs. female: 29.95%; male-female ratio: 2.33), hanging was the most frequent method (29.94%), and an increasing pattern in successful suicidal attempts was observed. The total YLLs were calculated to be 58669 years (14.71 per 1000 persons). Regardless of year or gender, suicide had the largest YLLs amongst those aged 15-29 years. Conclusion: Regarding the increasing trend in YLLs and observing the highest rate of successful suicidal attempts amongst active and productive members of community, a comprehensive inter organizational reaction is demanded.

Epidemiological study of hepatitis B and hepatitis C infection in Kohgiluyeh and Boyer‐Ahmad province (Iran) from 2008 to 2021: A cross‐sectional study

“…20 The opposite of linear regression is based on slope and loglinear regression is based on the APC. 21 Joinpoint regression analysis was performed using Joinpoint Regression Program (version 4.9.0.0). The protocol of this study was As illustrated in Figure 1, the highest and lowest number of cases of hepatitis B and C were reported in the age groups of 25-34 and 0-14 years, respectively.…”

“…This analysis fits a series of straight lines on a log scale to provide the annual percentage change (APC) in rates and specifies the point in time (calendar years) at which trends change significantly 20 . The opposite of linear regression is based on slope and log‐linear regression is based on the APC 21 …”

Years of Life Lost Due to Complete Suicide in Iran: A National Registry-Based Study

“…YLLs were computed for each age group using the earlier formula. However, to align with previous studies, 3 , 6 the calculated YLLs were integrated and reconstructed into 10-to-15-year age intervals. This step was taken to ensure consistency and comparability with earlier research efforts.…”

“…In Iran, limited research has been conducted on the YLL due to suicide. 3 , 6 , 7 This study thus aimed to estimate the YLL due to complete suicide in Iran. The study’s findings can inform targeted suicide prevention efforts, leading to more effective measures for preventing suicide and reducing the burden of complete suicide in Iran.…”

Burden of upper gastrointestinal cancers in the east of Golestan province (Golestan cohort study)

“…In this formula, N is equal to the number of deaths due to UGCs in a certain age and sex group, and L is equal to the standard life expectancy of deceased people of the same age and sex. 16 The mean age was used to calculate YLD. The disability weight was estimated using the items described in the GBD and was considered 0.544.…”
