Influence of post-disaster evacuation on incidence of hyperuricemia in residents of Fukushima Prefecture: the Fukushima Health Management Survey
Aim: After the Great East Japan Earthquake, over 160, 000 residents in Fukushima Prefecture were forced to evacuate the area around the Fukushima Daiichi power plant following nuclear accident there. Health problems in these evacuees have since become a major issue. We have examined the association between evacuation and incidence of hyperuricemia among residents in Fukushima. Methods: We conducted a cohort study of residents aged 40–90 years without hyperuricemia at the time of the Fukushima disaster. Among 8173 residents who met the inclusion criteria before the disaster, 4789 residents (men: 1971, women: 2818; follow-up duration: 1.38 years; and follow-up rate: 58.6%) remained available for follow-up examinations at the end of March 2013. The main endpoint was incidence of hyperuricemia, defined by the Japanese committee guidelines, using local health data from before and after the disaster. We divided participants by evacuation status and compared outcomes between groups. Using a logistic regression model, we estimated the odds ratio for incidence of hyperuricemia, adjusting for potential confounders, age, gender, waist circumference, physical activity, and alcohol consumption. Results: Incidence of hyperuricemia was higher in evacuees (men 10.1%; women 1.1%) than in non-evacuees (men 7.4%, women 1.0%). Evacuees had higher body mass index, waist circumference, triglycerides, LDL-cholesterol, fasting plasma glucose, HbA1c, and lower HDL-cholesterol after the disaster than non-evacuees. We found that evacuation was associated with incidence of hyperuricemia (adjusted odds ratio: 1.38; 95% confidence interval: 1.03-1.86). Conclusion: This is the first study to demonstrate an association between evacuation after a disaster and increased incidence of hyperuricemia
IAEA consultancy meeting on low-dose radiation for patients and population
This paper reports on the IAEA's Consultancy Meeting on "low-dose radiation for patients and population -Science, Technology and Society (STS) concepts for communication and perception among medical doctors and stakeholders-", which was held on October 21 and 22, 2020. The meeting consisted of seven presentation sessions, with a total of 27 presentations and 39 participants from seven countries. The meeting focused on various areas including environmental, food, and personal dosimetry;radiation and other secondary health effects after nuclear disasters;communication between medical professionals and patients or residents;and medical education on nuclear accidents. This meeting was convened to discuss STS perspectives related to nuclear emergencies, to share the findings of the Fukushima Health Management Survey and the current situation in Fukushima with international experts. The meeting confirmed the importance of coordinated recovery of affected areas and global preparedness in the aftermath of nuclear accidents
Parental Recognition of Bullying and Associated Factors Among Children After the Fukushima Nuclear Disaster: A 3-Year Follow-Up Study From the Fukushima Health Management Survey
This study examined parental recognition of bullying victimization and associated factors among evacuated children after the 2011 Fukushima Daiichi Nuclear Power Plant accident, using a 3-year follow-up data (wave 1: January 2012; wave 2: January 2013; wave 3: February 2014). The sample included the caregivers of 2,616 children in the first–sixth grades of elementary school, who lived in one of the 13 municipalities that were the target areas of the Mental Health and Lifestyle Survey, conducted as part of the Fukushima Mental Health Management Survey. Across 3 years, around 80% of caregivers responded “not true,” 15% responded “somewhat true,” and 5% responded “certainly true” in response to a question about bullying victimization of their children. Being male was significantly associated with the parental recognition of bullying victimization at wave 1 and wave 3. At wave 1, experiencing the nuclear plant explosion was significantly associated with parental recognition of bullying victimization. Moreover, age at wave 3 was negatively associated with parental recognition of bullying victimization. Our findings will be helpful for establishing community- and school-based mental health care for children, parents, and teachers
Cryptorchidism after the Fukushima Daiichi Nuclear Power Plant accident:causation or coincidence?
Cryptorchidism (undescended testes) is among the most common congenital diseases in male children. Although many factors have been linked to the incidence of cryptorchidism, and testicular androgen plays a key role in its pathogenesis, the cause remains unknown in most cases. Recently, a Japanese group published a speculative paper entitled, "Nationwide increase in cryptorchidism after the Fukushima nuclear accident." Although the authors implicated radionuclides emitted from the Fukushima accident as contributing to an increased incidence of cryptorchidism, they failed to establish biological plausibility for their hypothesis, and glossed over an abundance of evidence and expert opinion to the contrary. We assessed the adequacy of their study in terms of design setting, data analysis, and its conclusion from various perspectives. Numerous factors must be considered, including genetic, environmental, maternal/fetal, and social factors associated with the reporting of cryptorchidism. Other investigators have established that the doses of external and internal radiation exposure in both Fukushima prefecture and the whole of Japan after the accident are too low to affect testicular descent during fetal periods;thus, a putative association can be theoretically and empirically rejected. Alternative explanations exist for the reported estimates of increased cryptorchidism surgeries in the years following Japan's 2011 earthquake, tsunami, and nuclear crisis. Data from independent sources cast doubt on the extent to which cryptorchidism increased, if at all. In any case, evidence that radionuclides from the Fukushima Daiichi Nuclear Power Plant could cause cryptorchidism is lacking
Obesity and glucose metabolism abnormalities by post-disaster evacuation
Background: The objectives of this study were to determine the longer-term trends in childhood obesity and glucose metabolism abnormalities among residents of Fukushima Prefecture 5 years after the Great East Japan Earthquake. Methods: We evaluated the changes in height, weight, body mass index (BMI), BMI SD score, fasting plasma glucose (FPG) concentration, and hemoglobin A1c (HbA1c) among elementary and junior high school residents who had lived in the evacuation zone between 2011 and 2015. Results: Of the residents, 11,112 received health checks in 2011, while in 2012, 2013, 2014, and 2015, 5,737, 4522, 4297 and 3405 received health checks, respectively. The mean BMI SD score for all participants in 2011 was 0.149, and this score gradually decreased from 2011 to 2015. FPG levels and HbA1c levels for all participants with a BMI value +2SD or more in 2011 were higher than those in residents with a BMI value of less than +2SD. The frequency of participants with a FPG level of 126 mg/dl or more and the frequency of participants with a HbA1c level of 6.5% or more in 2011 were higher than those in 2012, 2013, and 2015. Conclusions: These results suggest that a number of pediatric residents suffered from obesity and glucose metabolism abnormalities. However, the longer-term observations indicated an improvement in obesity and glucose metabolism abnormalities. There was a strong association observed between obesity and glucose metabolism, thus, it is important to continue with health checks for children with obesity and strive to improve their health
Evacuation is a risk factor for diabetes development among evacuees of the Great East Japan earthquake: A 4-year follow-up of the Fukushima Health Management Survey
Psychosocial support for the examinees and their families during the secondary confirmatory examination: Analyses of support records at first visit
Background and Purpose The Thyroid Ultrasound Examination (TUE) program is conducted as part of the Fukushima Health Management Survey. Following the established criteria, examinees are called in for a secondary confirmation examination, which may induce high anxiety related to a thyroid cancer for both the examinees and their families. Therefore, Fukushima Medical University created the Thyroid Support Team to reduce anxiety. The purpose of this study is to analyze the psychosocial support for examinees and their families through two types of records, and to clarify the current issues and determine future directions of support. Materials and methods We analyzed 223 records of support for the first visit of examinees who attended the secondary confirmatory examination, conducted at Fukushima Medical University from September 2018 to March 2019. Results During the first visit, frequent topics and questions brought up by the examinees and their families were about the "Thyroid Ultrasound Examination (TUE) program" and "Examination findings". The Thyroid Support Team members assisted them by "Responding to questions", "Confirming the doctor's explanation" and "Providing information". The percentage of people with high anxiety decreased in both examinees and their family members after the examination. The level of anxiety was lower among those who had already taken the secondary confirmatory examination. Family members' anxiety was significantly higher than that of the examinees, and anxiety levels were highly correlated between examinees and their families. Conclusion The psychosocial support for examinees and their families was important in reducing their anxiety. Currently there are changes in social conditions and various opinions concerning the TUE. Thus, careful explanation and the need for decision-making supports for the examinees and their families increased. Also, we should take into account the aging of the examinees and expanding the available psychosocial support
Impact of lifestyle and psychosocial factors on the onset of hypertension after the Great East Japan earthquake: a 7-year follow-up of the Fukushima Health Management Survey
Natural disasters force many evacuees to change several aspects of their lifestyles. This longitudinal study aimed to investigate whether factors such as living environment and lifestyle factors were related to new-onset hypertension in survivors of the Great East Japan Earthquake over a long-term follow-up of up to 7 years after the earthquake. The present study examined data collected from 29,025 Japanese participants aged 39-89 years, sourced from general health checkups and the Fukushima Mental Health and Lifestyle Survey, which was conducted in 13 communities between 2011 and 2018. A total of 10,861 participants received follow-up examinations. During a median follow-up of 4.3 years, 3744 participants (1588 men, 41.4%; 2,156 women, 30.7%) had newly developed hypertension. Heavy drinking (adjusted hazard ratio 1.38, 95% confidence interval 1.21-1.57, p < 0.001) and obesity (adjusted hazard ratio 1.27, 95% confidence interval 1.19-1.37, p < 0.001) were significantly associated with new-onset hypertension after the disaster in multivariate-adjusted analysis. Furthermore, experiencing evacuation after the disaster was also significantly associated with the risk of new-onset hypertension in men (adjusted hazard ratio 1.14, 95% confidence interval 1.02-1.27, p = 0.016). The present study indicated that lifestyle factors, such as drinking and obesity, and evacuation experience in men had significant effects on the risk of new-onset hypertension in the long term after the earthquake
