研究了水量和卫生条件（单独或两者结合）对婴儿体重增加和身长增加的影响。 1984 年 7 月至 1985 年 1 月期间，从莱索托农村的 20 个村庄收集了 119 名婴儿的数据。在控制了潜在的混杂因素后，卫生条件和用水量增加对体重增加 (p = 0.007) 和身长增加 (p = 0.006) 之间的相互作用非常显着。最大的增长效应取决于拥有厕所的家庭以及在温暖潮湿的季节增加用水量。与只有厕所相比，当这两个积极因素都存在时，婴儿体重增加了 1.031 公斤（95% 置信区间 (CI) 0.420 至 1.642）和 2.028 厘米（95% CI 0.523 至 3.533）。在没有厕所的情况下，与不增加用水量相比，增加用水量仅导致体重增加 0. 1 05 千克（95% Cl -0. 1 75 至 0.385），长度增加 -0.309 厘米（95% Cl - 1.005 至 0.387）。同样，如果这两个因素都起作用，则与家庭仅增加用水量的婴儿相比，婴儿体重增加了 1.106 公斤（95% Cl 0.484 至 1.728）和 2.076 厘米（95% Cl 0.559 至 3.593）。在未加水组中，有厕所和没有厕所之间的生长差异为0.180千克（95％Cl -0.093至0.453）和-0.261厘米（95％Cl -0.951至0.429）。供水计划应强调使用更多的水来保持个人卫生，卫生计划应在用水量高或因教育计划而增加的地方安装厕所设施。
The effects of water quantity and sanitation, alone and in combination with each other, on infant weight gain and length gain were examined. Data on 119 infants were collected from 20 villages in rural Lesotho between July 1984 and January 1985. The interactions between sanitation and increased water usage for weight gain (p = 0.007) and length gain (p = 0.006) were significant after potential confounding was controlled. The biggest growth effects were dependent on families possessing a latrine and increasing their use of water during the warm, wet season. Infants gained 1.031 kg (95% confidence interval (CI) 0.420 to 1.642) and 2.028 cm (95% Cl 0.523 to 3.533) more when both positive factors were present, as compared with only having a latrine. Increasing water usage compared with not increasing water usage resulted in only 0. 1 05 kg (95% Cl -0. 1 75 to 0.385) more weight gain and -0.309 cm (95% Cl - 1.005 to 0.387) more length in the absence of a latrine. Similarly, infants gained 1.106 kg (95% Cl 0.484 to 1.728) and 2.076 cm (95% Cl 0.559 to 3.593) more if both factors were operating than did infants whose families only increased their water usage. In the nonincreased water group, the difference in growth between having and not having a latrine was 0.180 kg (95% Cl -0.093 to 0.453) and -0.261 cm (95% Cl -0.951 to 0.429). Water supply programs should emphasize use of more water for personal hygiene, and sanitation programs should install toilet facilities where water usage is high or has been increased because of an educational program.
