BACKGROUND:
Although numerous studies have indicated that exposure to natural disasters may increase survivors’ risk of post-traumatic stress disorder (PTSD) and anxiety, studies focusing on the long-term psychological outcomes of flood survivors are limited. Thus, this study aimed to estimate the prevalence of PTSD and anxiety among flood survivors 17 years after the 1998 Dongting Lake flood and to identify the risk factors for PTSD and anxiety.
METHODS:
This cross-sectional study was conducted in December 2015, 17 years after the 1998 Dongting Lake flood. Survivors in hard-hit areas of the flood disaster were enrolled in this study using a stratified, systematic random sampling method. Well qualified investigators conducted face-to-face interviews with participants using the PTSD Checklist-Civilian version, the Zung Self-Rating Anxiety Scale, the Chinese version of the Social Support Rating Scale and the Revised Eysenck Personality Questionnaire-Short Scale for Chinese to assess PTSD, anxiety, social support and personality traits, respectively. Logistic regression analyses were used to identify factors associated with PTSD and anxiety.
RESULTS:
A total of 325 participants were recruited in this study, and the prevalence of PTSD and anxiety was 9.5% and 9.2%, respectively. Multivariable logistic regression analyses indicated that female sex, experiencing at least three flood-related stressors, having a low level of social support, and having the trait of emotional instability were risk factors for long-term adverse psychological outcomes among flood survivors after the disaster.
CONCLUSION:
PTSD and anxiety were common long-term adverse psychological outcomes among flood survivors. Early and effective psychological interventions for flood survivors are needed to prevent the development of PTSD and anxiety in the long run after a flood, especially for individuals who are female, experience at least three flood-related stressors, have a low level of social support and have the trait of emotional instability.

Objective. This study mainly aimed to explore the association between brain-derived neurotropic factor (BDNF) Val66Met
polymorphism and posttraumatic stress disorder (PTSD) among flood survivors in China. Methods. Individuals who experienced
the 1998 Dongting Lake flood in Southeast Huarong, China, were enrolled in this study. Qualified health personnel carried out
face-to-face interviews with participants. PTSD was identified using PTSD Checklist-Civilian version (PCL-C). Blood samples
were collected from the participants to extract DNA for genotyping. Results. A total of 175 participants were enrolled in this study.
The prevalence of PTSD among flood survivors at 17-year follow-up was 16.0% (28/175). Individuals with PTSD were more likely to
be female, experience at least three flood-related stressors, experience at least three postflood stressors, and carry the Met than those
without PTSD. Compared with Val/Val homozygotes, Met carriers had higher scores of PCL-C (mean ± standard error: 23.60±7.23
versus 27.19±9.48, 𝑃 < 0.05).Multivariable logistic regression analysis indicated that Met carriers (aOR = 4.76, 95% CI = 1.02–22.15,
𝑃 < 0.05) were more likely to develop PTSD than Val/Val homozygotes. Conclusions. Met carriers for BDNF rs6265 are at higher
risk of developing PTSD and also exhibitmore severe PTSD symptoms than Val/Val homozygotes among flood survivors in China.

Prevalence of Posttraumatic Stress Disorder among Breast Cancer Patients: A Meta-analysis
Wu, Xin; Wang, Jieru; Cofie, Reuben; Kaminga, Atipatsa C.; Liu, Aizhong
BACKGROUND: Prevalence estimates of Posttraumatic Stress Disorder (PTSD) among breast cancer pa-tients varied widely in existing studies. This study aimed to provide an overall prevalence estimate of PTSD among breast cancer patients, and the prevalence estimates related to specific PTSD diagnosis tools.
METHODS: Systematic search of relevant articles was made from seven databases. Freeman-Tukey Dou-ble Arcsine Transformation was used to estimate the overall prevalence of PTSD. Sub-group and meta-regression analyses were used to investigate the between-study sources of heterogeneity. Publication bias was examined using Egger’s funnel plot and Begg test.
RESULTS: The pooled prevalence of PTSD among breast cancer patients was [9.6%, 95% confidence in-tervals (95%CI)=7.9-11.5%]. Studies that used Clinician Administered PTSD Scale-Form (CAPS) method alone yielded much higher prevalence (19.0%, 95%CI=13.1-25.5%, n=5) than three or fourth edition Structured Clinical Interview for Diagnostic and Statistical Manual (SCID) method alone (3.0%, 95%CI= 2.2-3.9%, n=11). Prevalence estimates for studies that used the methods: PTSD Checklist—Civilian Version (PCL-C) cut-off, PCL-C cluster, and Impact of Event Scale (IES) cut-off were (7.0%, 95%CI= 3.9-10.8%, n=10), (11.5%, 95%CI= 8.6-15.6%, n=11) and (15.1%, 95%CI= 12.3-18.2%, n=4), respectively. Heterogeneity between-study was substantial (I2=44.9–92.3%).
CONCLUSION: About 9.6% of the breast cancer patients would develop the PTSD symptoms. Those who were younger, non-Caucasian and recently completed treatment would be at a greater risk of developing PTSD.

BACKGROUND: Floods are some of the most common and destructive natural disasters in the world, potentially leading to both physical injuries and psychological disorders, including post-traumatic stress disorder (PTSD). PTSD can damage functional capacity and interfere with social functioning. However, little is known about recovery from PTSD after floods. This study used 2013-2014 follow-up data on survivors of the 1998 Dongting Lake flood who were diagnosed with PTSD in 2000 to measure the prevalence rate of PTSD at follow-up and identify predictors of recovery from the PTSD diagnosis in 2000.
METHODS: Participants included survivors who had been diagnosed as having PTSD in 2000 after the 1998 Dongting Lake flood. PTSD at follow-up was reassessed using the PTSD Checklist-Civilian version. Information on demographics, trauma-related stressors, post-trauma stressors, social support, and coping style were collected through face-to-face interviews. The association between the independent variables and PTSD at follow-up was analyzed using logistic regression analyses.
RESULTS: A total of 201 participants with a PTSD diagnosis in 2000 were included in this study. A total of 19.4 % of the flood survivors with PTSD in 2000 continued to suffer from PTSD in 2013-2014. In the multivariable logistic regression model, individuals who had lost relatives (OR = 12.37, 95 % CI = 2.46-62.16), suffered from bodily injury (OR = 5.01, 95 % CI = 1.92-13.08), had a low level of social support (OR = 5.47, 95 % CI = 1.07-27.80), or had a negative coping style (OR = 4.92, 95 % CI = 1.89-12.81) were less likely to recover from PTSD.
CONCLUSION: The prevalence rate of PTSD at follow-up indicates that natural disasters such as floods may have a negative influence on survivors' mental health for an extended period of time. Individuals who have lost relatives, suffered from bodily injury, had a low level of social support, or had a negative coping style were less likely to recover from PTSD. Therefore, effective psychological intervention measures are necessary for facilitating the recovery process from PTSD, especially for individuals with adverse prognostic factors.
