title: Maternal literacy modifies the effect of toilets and piped water on infant survival in Malaysia.
abstract: The effect of toilets, piped water, and maternal literacy on infant mortality was analyzed using data from the Malaysian Family Life Survey collected in 1976-1977. The effect of toilets and piped water on infant mortality was dependent on whether or not mothers were literate. The impact of having toilets was greater among the illiterate than among the literate, but the impact of piped water was greater among the literate than among the illiterate. The effect on the infant mortality rate for toilets decreased from 130.7 +/- 17.2 deaths in the absence of literate mothers to 76.2 +/- 25.9 deaths in the presence of literate mothers. The reduction in the mortality rate for maternal literacy dropped from 44.4 +/- 14.1 deaths without toilets to -10.1 +/- 23.9 deaths with toilets. Reductions in mortality rates for piped water increased from 16.7 +/- 12.7 deaths without literate mothers to 36.8 +/- 21.0 deaths with literate mothers. Similarly, reductions in the mortality rate for maternal literacy rose from 44.4 +/- 14.1 deaths in the absence of piped water to 64.5 +/- 19.5 deaths in the presence of piped water. The results from a logistic model provided inferences similar to those from ordinary least squares. The authors infer that literate mothers protect their infants especially in unsanitary environments lacking toilets, and that when piped water is introduced, they use it more effectively to practice better hygiene for their infants.
