A schistosomiasis research project, carried out in part of the Machakos area, yielded data by which it was possible to relate household egg outputs to some socioeconomic and other environmental variables. A significant negative correlation with schistosome scores was found for most variables when tested individually. Multiple regression analysis revealed a relatively strong relation with altitude and a much weaker association with some other variables. It is discussed whether the influence of altitude may be explained by differences in temperature, 'distance from infected water', or both. Furthermore it is hypothesized whether relations with social and economical variables are due to the fact that members of wealthier families stay away from contaminated water more often, have more knowledge of schistosomiasis and differ in hygienic behaviour.
在马查科斯地区部分地方开展的一项血吸虫病研究项目得出了一些数据，利用这些数据能够将家庭虫卵产出量与一些社会经济及其他环境变量联系起来。对大多数变量进行单独测试时，发现它们与血吸虫病评分呈显著负相关。多元回归分析表明，与海拔高度的关系相对较强，与其他一些变量的关联则弱得多。文中讨论了海拔高度的影响是否可以用温度差异、“与受感染水源的距离”或两者来解释。此外，还假设与社会和经济变量的关系是否归因于富裕家庭的成员更经常远离受污染水源、对血吸虫病有更多了解以及在卫生行为方面存在差异。
