Medical ecology of malaria and lifestyle change after the ethnic tension in the Northen Guadalcanal, Solomon Islands

在1980年代和90年代，所罗门群岛的东塔辛博科地区经历了人口迅速增长和西化，包括经常访问首都霍尼亚拉。附近有三个诊所，人们很容易就能得到氯喹和其他一些药物，因此死亡率正在下降。但在2000年前后，瓜达尔卡纳尔岛发生了种族紧张局势，人们在瓜达尔卡纳尔岛和马莱塔两岛之间发生了战斗。紧张局势改变了一切。大约66%的人失去了东塔辛博科的住房。由于桥梁和铺设的道路被毁，人们失去了前往霍尼亚拉的交通工具。诊所也被破坏，药品供应受到很大损害，本研究旨在澄清族裔紧张局势对东Tasimboko居民健康和生活的影响。Mbambala地区由7个村庄组成，可以分为两个。在4个村庄，人口自然/社会增长，但在其他3个村庄， 关于我们 由于搬迁到其他村庄或疟疾可能造成的高死亡率而改变或减少。尿液诊断提示健康状况总体改善。考虑到2006年2月尿pH值的双峰分布，以及较富裕（因此更肥胖）的人受到更多物质影响的事实，可以判断健康状况的变化是由于一些较富裕的肥胖人群由于购买的食物短缺而减少了能量摄入。然而，在2006年9月，尿液pH值分布变回单峰，大多数人每天服用购买的斯台普斯超过一次。WHOQOL-BREF显示生活质量处于中等水平，但环境领域得分相对较低。2006年9月研究后，立即重新建立了到霍尼亚拉的交通。它应该会使人们的生活发生翻天覆地的变化。前往霍尼亚拉的次数增加了，西瓜和葱等经济作物的种植也重新开始。一些村民开始在家里储存啤酒，然后卖给其他村民。购买食物的频率增加。2007年9月和2008年2月的WHOQOL-BREF澄清了环境领域得分的急剧增加，这可能反映了到霍尼亚拉的定期交通的重新建立。另一方面，在2008年2月，社会领域的得分似乎下降。种族紧张的心理后果也可能消失。疟疾的流行似乎在恶性疟原虫中持续下降。疟疾阳性者分布不均匀，而是集中在几个家庭中。应进一步研究地理/家庭效应。少

During 1980's and 90's, the East Tasimboko area of the Solomon Islands experienced rapid population growth and Westernization including frequent visit to Honiara, the capital city. There were three nearby clinics, where people easily obtained chloroquine and some other medicines so that mortality was decreasing. However, around 2000, the ethnic tension occurred in Guadalcanal Island, in which people fought between the two islands, Guadalcanal and Malaita. The tension changed everything. About 66% people lost their housings in East Tasimboko. People lost the transportation to Honiara due to the destruction of bridges and paved roads. Clinics were also broken so that availability of medicine was largely damaged.The present study aimed to clarify the effect of the ethnic tension on the health and life of the East Tasimboko residents. Mbambala area is made of 7 hamlets, which can be grouped into the two. In 4 hamlets, populations were naturally/socially increased, but in other 3 those unch … More anged or decreased due to move-out to other hamlets or high mortality probably caused by malaria. Urine diagnosis suggested overall improvement of health status. Considering the bimodal urine pH distribution in February 2006 and the fact that richer (and thus more obese) people suffered from more material effect, the change of health status can be judged as that some richer-obese people reduced energy intake due to the shortage of purchased food. However, in September 2006, urine pH distribution changed back to unimodal and most people took purchased staples more than once a day. WHOQOL-BREF showed moderate level of QOL, except that the scores of environmental domain were relatively lower than other domains.Immediately after the research in Sep. 2006, the transportation to Honiara has been re-established. It should make people's life drastically changed. Frequencies of going to Honiara were raised and cultivation of cash-crops like watermelon and shallot restarted. Some villagers started to store beer in their houses to sell them to other villagers. Frequency of eating purchased food increased. The WHOQOL-BREF in Sep. 2007 and Feb. 2008 clarified the drastic increase in the scores of environmental domain, which may reflect the re-establishment of regular transportation to Honiara. On the other hand, in Feb. 2008, the scores of social domain look decreasing. There is a possibility that psychological aftereffect of the Ethnic Tension has also disappeared. The prevalence of malaria seems to continuously decrease, amongst P. falciparum. Malaria positive individuals were not evenly distributed but converged into several households. The geographic/family effects should be further studied. Less
