Association between Laughter and Lifestyle Diseases after the Great East Japan Earthquake: The Fukushima Health Management Survey.

We investigated the association between the frequency of laughter and lifestyle diseases after the Great East Japan Earthquake. We included 41,432 participants aged 30-89 years in the Fukushima Health Management Survey in fiscal year 2012 and 2013. Gender-specific, age-adjusted and multivariable odds ratios of lifestyle diseases were calculated using logistic regressions stratified by evacuation status. Those who laugh every day had significantly lower multivariable odds ratios for hypertension (HT), diabetes mellitus (DM) and heart disease (HD) for men, and HT and dyslipidemia (DL) for women compared to those who do not, especially in male evacuees. The multivariable odds ratios (95% confidence intervals) of HT, DM and HD (non-evacuees vs. evacuees) for men were 1.00 (0.89-1.11) vs. 0.85 (0.74-0.96), 0.90 (0.77-1.05) vs. 0.77 (0.64-0.91) and 0.92 (0.76-1.11) vs. 0.79 (0.63-0.99), and HT and DL for women were 0.90 (0.81-1.00) vs. 0.88 (0.78-0.99) and 0.80 (0.70-0.92) vs. 0.72 (0.62-0.83), respectively. The daily frequency of laughter was associated with a lower prevalence of lifestyle disease, especially in evacuees.

Culturally sensitive disaster nursing by Public health nurses in Japan.

OBJECTIVE: To clarify culturally sensitive disaster nursing by public health nurses (PHNs) in Japan, an island nation located on the Pacific Rim, with regard to PHNs' intentions and comforting supports for affected people. DESIGN: Qualitative descriptive study. SAMPLE: Participants were 17 local PHNs and 13 affected people in nine disaster-affected municipalities throughout Japan. MEASUREMENTS: Semi-structured interviews were conducted between October 2018 and July 2019. Two types of categories were qualitatively created: categories for PHNs' culturally sensitive disaster nursing actions, including their intentions; and categories for comforting supports that PHNs provided for affected people through the four phases of disaster. The relationship between these two types of categories was determined. Cultural factors were extracted from the culturally sensitive disaster nursing actions of PHNs and categorized. RESULTS: Regarding intentions, in the acute phase, PHNs utilized culture. In the sub-acute phase, they utilized, acted based on, followed, thought of, and balanced cultural knowledge. In the mid-term-phase, they utilized, thought of, followed, and balanced with local culture. In the long-term phase, they merged, thought of, balanced, utilized, and followed local cultural practices. The actions associated with these intentions corresponded to comforting supports for affected people. Cultural factors, such as transportation style, were obtained in each phase. CONCLUSION: To enhance the resilience of a community affected by disaster, PHNs should focus on maximizing, preserving, and accommodating culture to maintain familiar life patterns when people's circumstances are totally disrupted by powerful forces of nature.

The association between body mass index and recovery from post-traumatic stress disorder after the nuclear accident in Fukushima.

Post-traumatic stress disorder (PTSD) and obesity share common risk factors; however, the effect of obesity on recovery from PTSD has not been assessed. We examined the association between body mass index (BMI) and recovery from PTSD after the Great East Japan Earthquake. We analyzed 4356 men and women with probable PTSD aged ≥ 16 years who were living in evacuation zones owing to the radiation accident in Fukushima, Japan. Recovery from probable PTSD was defined as Post-traumatic Stress Disorder Checklist-specific scores < 44. Using Poisson regression with robust error variance adjusted for confounders, we compared the prevalence ratios (PRs) and 95% confidence intervals (CIs) for this outcome in 2013 and 2014. Compared with point estimates for normal weight (BMI: 18.5-24.9 kg/m2), especially in 2013, those for underweight (BMI: < 18.5 kg/m2) and obesity (BMI: ≥ 30.0 kg/m2) tended to slightly increase and decrease, respectively, for recovery from probable PTSD. The multivariate-adjusted PRs (95% CIs) for underweight and obesity were 1.08 (0.88-1.33) and 0.85 (0.68-1.06), respectively, in 2013 and 1.02 (0.82-1.26) and 0.87 (0.69-1.09), respectively, in 2014. The results of the present study showed that obesity may be a useful predictor for probable PTSD recovery. Obese victims with PTSD would require more intensive support and careful follow-up for recovery.

Association between Psychological Factors and Evacuation Status and the Incidence of Cardiovascular Diseases after the Great East Japan Earthquake: A Prospective Study of the Fukushima Health Management Survey.

Evidence regarding the effect of psychological factors and evacuation on cardiovascular disease occurrence after large-scale disasters is limited. This prospective study followed up a total of 37,810 Japanese men and women aged 30-89 years from the Fukushima Prefecture with no history of stroke or heart disease at baseline (2012), until 2017. This period included 3000 cardiovascular events recorded through questionnaires and death certificates. The participants' psychological distress, trauma reaction, and evacuation status were defined, and divided into four groups based on combinations of psychological factors and evacuation status. We calculated the hazard ratios and 95% confidence intervals for only psychological, only evacuation, or both of them compared with neither using Cox proportional hazard models. Psychological factors along with evacuation resulted in approximately 5% to 25% higher magnitude of stroke and heart disease risk than psychological factors only among men. Compared to neither, the multivariable hazard ratios of those with both psychological distress and evacuation were 1.75 for stroke and 1.49 for heart disease, and those of both trauma reaction and evacuation were 2.01 and 1.57, respectively, among men. Evacuation combined with psychological factors increased the risk of stroke and heart disease risks especially in men after the Great East Japan Earthquake.

The association between self-reported sleep dissatisfaction after the Great East Japan Earthquake, and a deteriorated socioeconomic status in the evacuation area: the Fukushima Health Management Survey.

BACKGROUND: Currently, few studies have thoroughly investigated the socioeconomic factors related to sleep problems among evacuees following a disaster. OBJECTIVES: To examine sleep problems in evacuees using data from a large-scale cohort survey of evacuees conducted after the 2011 Great East Japan Earthquake (GEJE). METHODS: In sum, 73,433 residents who were living in evacuation zones responded to The 2011 Fukushima Health Management Survey. We excluded 16,659 participants who did not answer the question about sleep problems or those younger than 20 years. Thus, data from 56,774 participants (24,959 men and 31,815 women) were used for this analysis. Evacuees' self-reported sleep dissatisfaction was determined based on their response to the question 'Are you satisfied with the quality of your sleep? '. The response options 'Unsatisfied' and 'Very unsatisfied' were considered as the outcome for the present study. Prevalence ratios (PRs) and 95% confidence intervals (CIs) for the prevalence of self-reported sleep disturbance were estimated using modified Poisson regression models. RESULTS: Of the qualifying survey respondents, 20.3% (4387 men and 7128 women) reported sleep dissatisfaction. Compared with participants living in their own or a relative's home (PR = 1), those living in temporary housing or rental accommodation had a higher prevalence of sleep dissatisfaction (1.47; 95% CI 1.44-1.50 and 2.16; 95% CI 2.07-2.26 in men; 1.39; 95% CI 1.36-1.41 and 1.92; 95% CI 1.86-1.99 in women). Higher educational attainment was also associated with a higher prevalence of sleep dissatisfaction in men, as were job loss and decreased income in both men and women. CONCLUSION: Self-reported sleep dissatisfaction after the GEJE was associated with a deteriorated socioeconomic status among evacuees. However, future longitudinal studies are warranted.

[Association between evacuation condition and habitual physical activity in Great East Japan Earthquake evacuees: The Fukushima Health Management Survey].

Objectives: Prevalence of life-style disease has increased dramatically in evacuees due to the Great East Japan Earthquake. One reason may be that physical activity level decreased from life environment changes due to evacuation. However, associations between evacuation condition and habitual physical activity have not been studied. We examined this association in Fukushima residents who participated in the Fukushima Health Management Survey. Methods: In this study, 37,843 evacuees from 13 municipal evacuation zones from the nuclear-power accident caused by the Great East Japan Earthquake, born before April 1, 1995, were included in the analysis. Evacuation condition was defined by disaster living place (13 zones), evacuation place (inside or outside the prefecture), and current living status (evacuation shelter or temporary housing, rental housing/ apartment, and relative's home or own home). Habitual physical activity was defined from self-administered questionnaires as participants who responded "almost every day" and "2-4 times/week" of regular exercise. In the analysis, habitual physical activity prevalence was aggregated by gender and variables (living place in the disaster, evacuation place, and current living status). Prevalence was adjusted for age, disaster living place, evacuation place, and current living status by standard analysis of covariance methods. Results: Adjusted prevalences of habitual physical activity were: men, 27.9-46.5%; women, 27.0-43.7% in each disaster living place. The differences were 18.6% point in men and 16.7% point in women. For evacuation place, physical activity outside the prefecture for men (37.7%) and inside the prefecture for women (32.1%) were higher, but those differences were only 2.2% point and 1.8% point in men and women, respectively. For current living status, physical activity of those in rental housing/ apartment was the lowest; evacuation shelter or temporary housing was the highest in both genders (men: 38.9%, women: 36.7%). Compared with residents in evacuation shelter or temporary housing, those in rental housing/apartment were 5.4% point and 7.1% point lower and those in relative's home or own home were 2.0% point and 4.2% point lower in men and women. Conclusion: Habitual physical activity in residents who lived in 13 municipal evacuation zone differed by disaster living place and current living status, while it was similar regardless of placement in the prefecture. In particular, prevalence was the lowest in participants who lived in rental housing/ apartment. We need to plan and perform additional life-style disease prevention strategies for participants who become isolated.

Exposure of family members to antineoplastic drugs via excreta of treated cancer patients.

PURPOSES: (a) To measure the urinary excretion of antineoplastic drugs of three patients during 48 h after the administration of cyclophosphamide (two patients) and 5-fluorouracil (one patient). (b) To evaluate environmental contamination with antineoplastic drugs via excreta of patients in the home setting. (c) To evaluate exposure of family members to antineoplastic drugs by measuring the drugs in their urine during the 48 h after completion of the chemotherapy by the patients. METHODS: Two patients were administered cyclophosphamide by i.v. bolus injection. One patient was administered 5-fluorouracil by i.v. bolus injection and thereafter immediately administered the same drug by continuous infusion for 46 h. Urine samples from the patients administered cyclophosphamide and their family members, and wipe samples from their home environment, were analysed for the unchanged form of cyclophosphamide. For 5-fluorouracil, the urine samples from the patient and the family member were analysed for the 5-fluorouracil metabolite α-fluoro-ß-alanine. Wipe samples were analysed for 5-fluorouracil. Drugs were detected and quantified with gas chromatography in tandem with mass spectroscopy-mass spectroscopy or by high-performance liquid chromatography with ultraviolet-light detection. RESULTS: A total of 35 and 16 urine samples were collected from the three patients and their family members, respectively. The drugs were detected in all samples. Cyclophosphamide was detected at levels of 0.03-7.34 ng/cm(2) in 8 of the 12 wipe samples obtained from the homes of the patients administered cyclophosphamide. For the patient administered 5-fluorouracil, drug levels in his home environment were below the limit of detection. CONCLUSION: We demonstrated contamination of the home setting and exposure of family members to cyclophosphamide via the excreta of outpatient receiving chemotherapy. Exposure of the family member of the patient administered 5-fluorouracil was also demonstrated. These findings indicate the importance of strict precautions by the members of treated cancer patients as well as healthcare workers, to reduce the risk of exposure to antineoplastic drugs.

[Prospective study of the relation between exercise performance for health promotion, self-efficacy, and outcome expectation of elderly people].

AIM: Self-efficacy and outcome expectation are psychological factors influencing performance behavior. Self-efficacy is a person's confidence that one can successfully perform the behavior to produce depend outcomes. Outcome expectation is the estimate that a favorable consequence will be produced by the behavior. These psychological factors are important reasons to perform exercise for health promotion among elderly people, but little is known about the relations among them. Therefor this study examined the relation among exercise for health promotion, self-efficacy, and outcome expectation of elderly people. METHODS: This was a prospective study using self answered questionnaire. Data were collected from before and three follow-up investigations at 3 months intervals over a 9 month period. The sample was composed of 43 elderly people who applied for exercise program. RESULTS: A strong correlation (r = 0.375 - r = 0.412) was observed between self-efficacy and exercise performance after three months. There was a strong correlation (r = 0.349 - r = 0.665) between outcome expectation and exercise performance at 3 months, 6 months, and 9 months. CONCLUSION: These findings suggest that self-efficacy and outcome expectation are significant predictors of exercise performance for health promotion in elderly people.
