Human Ecological Study on Health Impacts of Volcanic Eruption

1995年云禅府根山的火山喷发已经停止，但岛原市和府前镇的许多居民仍然与生存经济和居住地点的变化所带来的许多困难相矛盾。通过火山喷发进行的连续实地研究揭示了以下几点。1)由于居民为躲避剧烈喷发而避难，灾区人口迅速减少，即使火山活动停止后，这种趋势仍在继续。在爆发初期，死胎率迅速上升。呼吸系统疾病的死亡率似乎高于其他地区。对呼吸系统**的慢性影响应持续检查。2)随着出疹次数的减少，眼部和呼吸系统的刺激性症状迅速减少，而呼吸系统的刺激性症状则缓慢减少。3)通过对学龄期儿童哮喘与家庭环境的关系分析，火山爆发后家庭成员的变化似乎对哮喘发作有显著影响。4)后续研究表明，即使火山喷发已经停止，难民的心理健康状况仍然紧张。心理保健管理是预防创伤后精神障碍的必要措施。

The volcanic eruption of Unzen-Fugen mountain has ceased in 1995 but many dwellers in Shimabara city and Fukae town are still conflicting with many difficulties caused by changes of subsistance economies and residential places. Continious field studies through volcanic eruption revealed following points. 1) Populations of disasterous areas had rapidly decreased by refuge of dwellers for avoiding acute eruption and this trend is still continued even after volvanic action has ceased. The rapid increase of still birth rate was observed at the early stage of eruption. Mortality rate from respiratory diseases seems to be higher than other areas. Chronic effects on respiratory system **oud be continously examined. 2) According with decline of frequency of eruption, irritant symptoms in eyes and thoat have rapidly became to be less frequent, but those in respiratory system have slowly decreased. 3) By analysis on relationship with asthma and domestic environment among school children, changes of family member by volcanic eruption seemed to affect significantly the incidence of asthma attack. 4) Follow up studies revealed that mental health condition of refugees hsve been stressful even though the volcanic eruption has ceased. Administration on mental health care should be necessary for preventing Post Traumatic Disorders.
