BackgroundOn March 11, 2011, Japan experienced an unprecedented combination of earthquake/tsunami/nuclear accidents (the Great East Japan Earthquake; GEJE). We sought to identify mental health and psychosocial consequences of this compound disaster.MethodA systematic literature review was conducted of quantitative research articles addressing mental health of survivors and the psychological impact of the GEJE. For articles between March 2011 and December 2014, PubMed, PsychINFO, and EMBASE databases were searched with guidance on literature review method.ResultsForty-nine studies met the inclusion criteria. A substantial proportion of the affected individuals experienced considerable psychological distress. Mental health outcomes included, but were not limited to, posttraumatic stress disorder, depression, and anxiety symptoms. Physical health changes, such as sleeping and eating disturbances, also occurred. In Fukushima, radioactive release induced massive fear and uncertainty in a large number of people, causing massive distress among the affected residents, especially among mothers of young children and nuclear plant workers. Stigma was additional challenge to the Fukushima residents. The review identified several groups with vulnerabilities, such as disaster workers, children, internally displaced people, patients with psychiatric disorders, and the bereaved.ConclusionsFollowing the GEJE, a considerable proportion of the population was mentally affected to a significant degree. The affected individuals showed a wide array of mental and physical consequences. In Fukushima, the impact of nuclear disaster was immense and complex, leading to fear of radiation, safety issues, and stigma issues.
Alcohol-related injuries in college students are a major public health problem worldwide. We clarified the association between excessive drinking and alcohol-related injuries in Japanese college students. This was a cross-sectional study with a self-administered questionnaire. From January to March 2013, we sampled all college students and graduate students aged 20 years or older during annual health examinations at three colleges in Mie Prefecture in Japan. The questionnaire assessed the frequency of alcohol drinking, amount of alcohol consumed per day, binge drinking during the past year, alcohol-related injuries during the past year, and demographic data. Logistic regression analysis was conducted on the association between excessive alcohol use and alcohol-related injuries. A total of 2,842 students underwent health examinations, of whom 2,177 (76.6%) completed the questionnaire. Subjects included 1,219 men (56.0%) and 958 women (44.0%). Eighty-eight men (7.2%) and 93 women (9.7%) were classified as excessive weekly drinkers, while 693 men (56.8%) and 458 women (47.8%) were determined to be binge drinkers. Eighty-one men (6.6%) and 26 women (2.7%) had experienced alcohol-related injuries during the past year. In the logistic regression analysis, binge drinkers (odds ratio 25.6 [8.05-81.4]) and excessive weekly drinkers (odds ratio 3.83 [2.41-6.09]) had a history of significantly more alcohol-related injuries, even after adjusting for age and sex. In conclusion, alcohol-related injuries in college students in Japan were strongly associated with excessive drinking. As a strategy for preventing such injuries in this population, an interventional study is required to identify effective methods for reducing excessive alcohol use.
Binge drinking by college students is a problematic behavior. However, data on binge drinking and the reasons for drinking by college students in Japan are scarce. We explored the reasons for drinking among college students. The study used a cross-sectional design and a self-administered questionnaire. From December 2016 to March 2017, we sampled undergraduate and graduate students aged 20 or older at 35 colleges in the Kanto region of Japan. The questionnaire addressed 1) frequency of drinking alcohol, 2) amount of drinking per day, 3) frequency of binge drinking in the past year, and 4) reasons for drinking (with 12 possible responses). The t-test was used to compare the means between binge drinkers and non-binge drinkers. Logistic regression analysis was conducted on binge drinking and the reasons for drinking. The participants included 303 men and 260 women. Significant differences between men and women included the presence of binge drinking (men: 74.9%; women: 59.6%). Among male students, the statistically significant reasons given for binge drinking were "to feel happy or be in a good mood" and "to relieve stress," whereas among female students, the reasons were "to feel happy or be in a good mood," "to facilitate interpersonal relationships," "to forget something bad," and "to relieve stress." The reasons for drinking associated with binge drinking were identified. It is important to incorporate these results into preventive education about binge drinking aimed at college students in Japan.
The association between perfectionism and addictive behaviors has been examined in previous literature; however, few pieces of research have investigated the mediating and moderating mechanisms underlying this relationship. Using a sample of 2016 Chinese college students, the present study examined the mediator of depression between maladaptive perfectionism and Internet addiction and the moderator of gender in such associations. The findings indicated that maladaptive perfectionism was directly related to students’ Internet addiction and indirectly predicted students’ Internet addiction via the mediator of depression. Gender moderated the direct effect, rather than the indirect effect, of maladaptive perfectionism on Internet addiction. Even though males reported a lower score on Internet addiction compared to females, the effect of maladaptive perfectionism on Internet addiction was stronger for males than for females. These findings revealed the psychological mechanisms from perfectionism to Internet addiction, which contributed to the theoretical development in addiction research and provided implications for interventions to reduce Internet addiction among Chinese college students.
Binge drinking is a common and risky behavior among college students. In Japan, however, research on the prevalence of binge drinking and alcohol-related consequences, and the relationship between them, is currently scant. The aim of this study is to examine the status of binge drinking and alcohol-related problems, and the relationship between them, among Japanese college students. We conducted a crosssectional survey of college students who participated in a health seminar or lecture including alcoholrelated contents from December 2018 to January 2019. Drinking patterns and alcohol-related consequences were assessed using the Brief Young Adult Alcohol Consequences Questionnaire (B-YAACQ) and demographic data. A total of 382 students participated in the seminar, of whom 280 agreed to cooperate in this study and 249 had drinking experience. A total of 88 men (67.7%) and 42 women (32.2%) were classified as binge drinkers. Binge drinkers more significantly experienced various consequences, such as hangover, feeling remorse and embarrassing behavior and some of them were suspected of physical dependence. Furthermore, logistic analysis revealed that among men, the B-YAACQ scores of binge drinkers were 2.01-fold higher those of non-binge drinkers. The findings of this study indicated that binge drinking may cause not only physical consequences but also mental and social problems, especially among men. It is important to tell college students these risks properly not to engage in binge drinking.
