New Bone Fractures Findings from Fukushima Medical University Published (Association between post-traumatic stress disorder symptoms and bone fractures after the Great East Japan Earthquake in older adults: a prospective cohort study from the …)

2021 JAN 27 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- Investigators publish new report on bone fractures. According to news originating from Fukushima Medical University by NewsRx correspondents, research stated, “It has been reported that psychological stress affects bone metabolism and increases the risk of fracture. However, the relationship between bone fractures and post-traumatic stress disorder (PTSD) is unclear.”

Funders for this research include National Health Fund for Children and Adults Affected by the Nuclear Incident.

Our news correspondents obtained a quote from the research from Fukushima Medical University: “This study aimed to evaluate the effects of disaster-induced PTSD symptoms on fracture risk in older adults. This study evaluated responses from 17,474 individuals aged 65 years without a history of fractures during the Great East Japan Earthquake who answered the Mental Health and Lifestyle Survey component of the Fukushima Health Management Survey conducted in 2011. The obtained data could determine the presence or absence of fractures until 2016. Age, sex, physical factors, social factors, psychological factors, and lifestyle factors were subsequently analyzed. Survival analysis was then performed to determine the relationship between the fractures and each factor. Thereafter, univariate and multivariate Cox proportional hazard models were constructed to identify fracture risk factors. In total, 2,097 (12.0%) fractures were observed throughout the follow-up period. Accordingly, univariate and multivariate Cox proportional hazard models showed that PTSD symptoms (total PTSD checklists scoring 44) [hazard ratio (HR): 1.26; 95% confidence interval (CI): 1.10-1.44; P = 0.001], history of cancer (HR: 1.49; 95% CI: 1.24-1.79; P < 0.001), history of stroke (HR: 1.25; 95% CI: 1.03-1.52; P = 0.023), history of heart disease (HR: 1.30; 95% CI: 1.13-1.50; P < 0.001), history of diabetes (HR: 1.23; 95% CI: 1.09-1.39; P < 0.001), current smoking (HR: 1.29; 95% CI: 1.02-1.63; P = 0.036), and high dissatisfaction with sleep or no sleep at all (HR: 1.33; 95% CI: 1.02-1.74; P = 0.035) promoted a significant increase in fracture risk independent of age and sex.”

According to the news reporters, the research concluded: “The present study indicates that disaster-induced PTSD symptoms and insomnia contribute to increased fracture risk among older adults residing in evacuation areas within the Fukushima Prefecture.”
