Lifestyle Factors Associated With Undernutrition in Older People After the Great East Japan Earthquake. A Prospective Study
Background: The aim of this study was to conduct a longitudinal examination to assess the relationship between lifestyle habits, including exercise habits, and the incidence of undernutrition after the Great East Japan Earthquake.
Methods: We included residents aged 60 years or more who lived in the evacuation area municipalities from 2008 to 2010 before the disaster. A total of 31,411 participants (14,350 men and 17,061 women) who underwent a physical examination during this period were followed-up through 2017. We estimated the associations between undernutrition after the disaster and lifestyle factors using a multivariate-adjusted analysis with a Cox proportional hazard regression model. The variables included the model were evacuation, exercise habits, meals before bedtime, history of gastrointestinal surgery, history of lifestyle-related diseases, and 2 or more subjective symptoms.
Results: In all, 1721 of the 13,378 participants were newly undernourished after the disaster. The statistically significant variables influencing the occurrence of undernutrition were non-evacuation (hazard ratio, 1.31; 95% confidence interval 1.17–1.47), poor exercise habits (HR, 1.14; 95% CI 1.03–1.50), and poor physical activity (HR, 1.12; 95% CI 1.01–1.25). Other related variables were surgical history, lifestyle-related diseases, and two or more subjective symptoms. No statistically significant interactions with exercise habits were identified for each lifestyle factor.
Conclusions: These results suggest that regular exercise and/or maintaining physical activity might be important, regardless of sex, other lifestyle habits, or past medical history, in preventing undernutrition following a disaster.
