This paper examines comparable national surveys of breastfeeding from the Philippines carried out in 1973 and 1983. The probability of breastfeeding at selected infant ages is estimated, using the weighted life table. The conclusions are that a 5 per cent decline in the proportion of infants ever breast-fed occurred during the referenced period, and that median length of breastfeeding remained essentially the same.
本文考察了1973年和1983年在菲律宾开展的全国性母乳喂养对比调查。运用加权生命表对选定婴儿年龄的母乳喂养概率进行了估算。得出的结论是,在所述期间,曾经接受母乳喂养的婴儿比例下降了5%,而母乳喂养的中位时长基本保持不变。
