“…Our finding that suicide risk among cancer survivors was higher in large cities than in small cities or rural areas conflicts with previous reports about the general Korean population (22,33). Studies are needed to determine how type of residential area is related to suicide risk.…”

“…We built the regression model reflecting variables that correlated significantly with risk in univariate analysis (sex, age at diagnosis, year of diagnosis, time to suicide or cancer death, site of cancer, marital status, and educational status) and known suicide risk factors, namely, sex (1,3), age at diagnosis (6,21), marital status (1, 3), site of cancer (1,(3)(4)(5), and residential area (22,33). Because we obtained the sociodemographic data from a mortality database, the study was necessarily limited to deceased patients.…”

“…The number of people who live with the aftereffects of cancer and its treatment-disability, fear of recurrence, and economic burden-is growing (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). Factors related to suicide include mainly clinical characteristics such as age at diagnosis (6,21), prognosis (5), psychiatric status (21,22), stage (1,3,6), time since diagnosis (1,6,21), and period of diagnosis (1,(4)(5)(6), and sociodemographic characteristics such as sex (1,3), race (1,21), and marital status (1,3,21).…”

Background: As the number of cancer survivors increases, suicide risk approaches that of the general population. We therefore investigated suicide rates and risk factors among Korean cancer patients.Methods: We observed 816,295 cancer patients for 3,007,294 person-years from 1993 to 2005 through a nationwide cancer registry. We calculated their sex-and age-standardized mortality ratios (SMR) and studied suicide risk factors using rate ratios (RR) based on a log-linear Poisson regression model.Results: Compared with the Korean general population, the suicide rate among cancer patients was high [SMR, 2.00; 95% confidence interval (95% CI), 1.91-2.08]. The rates were highest in the year following the cancer diagnosis (SMR, 3.45; 95% CI,) and were still elevated 5 years later (SMR, 1.23; 95% CI, 1.12-1.36). The clinical groups at highest risk were male pancreas cancer patients (SMR, 6.01; 95% CI, 4.33-8.33) and female lung cancer patients (SMR, 3.55; 95% CI, 2.55-4.94). The sociodemographic groups at highest risk were those who had no spouse versus those who were married (RR, 1.50; 95% CI, 1.35-1.68), those who were not employed versus those who were (RR, 1.39; 95% CI, 1.26-1.54), and those who did not have high school education versus those who had (RR, 1.52; 95% CI, 1.30-1.79).Conclusions: Korean cancer patients are at increased risk of suicide. Both clinical and sociodemographic factors play a role.Impact: There is a need for social support and suicide prevention strategies for cancer survivors in Korea.

ImportanceDespite individual studies suggesting that sex differences exist in the association between alcohol use disorder (AUD) and suicide, most existing systematic reviews and meta-analyses have reported associations across the sexes.ObjectiveTo estimate the sex-specific association between AUD and suicide mortality.Data SourcesEmbase, MEDLINE (including MEDLINE In-Process), PsycINFO, PubMed, and Web of Science were searched from database inception to April 27, 2022.Study SelectionInclusion criteria consisted of the following: (1) original, quantitative study, (2) inclusion of a measure of association and its corresponding measure of variability (or sufficient data to calculate these [eg, 95% CI]), and (3) results stratified by sex.Data Extraction and SynthesisData extraction was completed by one reviewer and then cross-checked by a second reviewer. Risk of bias was assessed by study design. Categorical random-effects meta-analyses were conducted to obtain sex-specific pooled estimates of the association between AUD and suicide mortality risk. Methodological moderators (ie, study design and comparator group) were assessed using sex-stratified meta-regressions.Main Outcomes and MeasuresThe association between AUD and suicide mortality.ResultsA total of 16 347 unique records were identified in the systematic search; 24 studies were ultimately included for 37 870 699 participants (59.7% male and 40.3% female) (23 risk estimates for male and 17 for female participants). Participants ranged in age from 15 years to 65 years or older. Sex-specific meta-regression models indicated that study design (ie, longitudinal vs cross-sectional study design) affected the observed association between AUD and suicide mortality for both male participants (log odds ratio, 0.68 [95% CI, 0.08-1.28]; P = .03) and female participants (log odds ratio, 1.41 [95% CI, 0.57-2.24]; P &lt; .001). For males and females, among longitudinal studies, the pooled odds ratios were 2.68 (95% CI, 1.86-3.87; I2 = 99% [n = 14]) and 2.39 (95% CI, 1.50-3.81; I2 = 90% [n = 11]), respectively.Conclusions and RelevanceThis systematic review and meta-analysis yielded substantive evidence that AUD was associated with suicide mortality and that the association was similar across the sexes. The findings underscore the importance of identifying and treating AUD as part of a comprehensive suicide prevention strategy.
