Abstract
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.
