Psychological distress in children and adolescent disaster survivors.

BACKGROUND: This study aimed to clarify the association between mental and behavioral changes and subsequent psychological distress among children and adolescents living in areas affected by the 2011 Great East Japan Earthquake. METHODS: We conducted a two-wave study, with waves 1 and 2 occurring in 2011 and 2014, respectively. Data of 462 respondents aged 9-14 years during wave 1 and who participated in both surveys were used in the present analysis. A factor analysis was performed using the mental and behavioral changes reported by respondents in wave 1. Psychological distress was defined as a score of ≥5 on the six-item Kessler Psychological Distress Scale, as measured in wave 2. With the factors generated in this analysis set as independent variables, the odds ratios (OR) (95% confidence intervals, 95% CIs) for psychological distress were calculated using logistic regression, adjusting for age, sex, house damage, living environment, and loss of family or friends. RESULTS: Psychological distress was present in 108 (23.4%) of the respondents. The factor analysis yielded three factors describing mental and behavioral changes: interpersonal issues, brain fog, and anxiety and panic. Of these, interpersonal issues were significantly associated with subsequent psychological distress, with an OR of 2.59 (95% CI 1.58-4.25). This association did not change even when stratified by age and sex. CONCLUSIONS: This study suggests that interpersonal issues are a significant predictor of psychological distress in children and adolescents living in areas affected by a large-scale disaster.

Association between Milk Intake and Incident Stroke among Japanese Community Dwellers: The Iwate-KENCO Study.

We aimed to evaluate the association between the milk consumption and incident stroke in a Japanese population, where milk consumption is lower than that of Western countries. In total, 14,121 participants (4253 men and 9868 women) aged 40-69 years, free from cardiovascular diseases (CVD) were prospectively followed for 10.7 years. Participants were categorized into four groups according to the milk intake frequency obtained from a brief-type self-administered diet questionnaire. The adjusted HRs of total stroke, ischemic stroke and haemorrhagic stroke associated with milk intake frequency were calculated using the Cox proportional hazards model. During the follow-up, 478 stroke cases were detected (208 men and 270 women). Compared to women with a milk intake of <2 cups/week, those with an intake of 7 to <12 cups/week had a significantly low risk of ischemic stroke in a model adjusting CVD risk factors; the HR (95% CI) was 0.53 (0.32-0.88). No significant associations were found in men. This study suggested that milk intake of 7 to <12 cups/week decreased the risk of ischemic stroke in Japanese women. Milk intake of about 1 to <2 cups/day may be effective in the primary prevention of ischemic stroke in a population with low milk intake.
