The prevalence of night blindness during pregnancy and lactation was assessed in a sample of 426 women living in the rural terai of Nepal. These women were also examined for ocular signs of vitamin A deficiency. Among 241 lactating women, 16.2% reported experiencing night blindness at some time during the pregnancy that produced the infant they were now breast-feeding. Among 185 pregnant women, 8.1% reported being night-blind at the time of the interview. The odds of night blindness in the current pregnancy were six times greater for women who reported night blindness in their previous pregnancy. Night-blind women were more likely to come from households with lower socioeconomic status. Teenage women and those over the age of 30 were at highest risk, particularly those of higher parity within these age groups. Vitamin A deficiency, for which night blindness is a marker, seems to be a problem in this population of pregnant and lactating women, with potential health consequences for women and their infants.
对居住在尼泊尔特莱平原农村地区的426名妇女进行抽样调查，评估她们在孕期和哺乳期夜盲症的患病率。这些妇女还接受了维生素A缺乏的眼部体征检查。在241名哺乳期妇女中，16.2%的人报告在孕育她们正在哺乳的婴儿的孕期曾在某个时候出现过夜盲症。在185名孕妇中，8.1%的人报告在接受访谈时患有夜盲症。曾在前次孕期出现过夜盲症的妇女，本次孕期患夜盲症的几率高出六倍。夜盲妇女更有可能来自社会经济地位较低的家庭。青少年女性和30岁以上女性风险最高，尤其是这些年龄组中生育次数较多的女性。夜盲症作为维生素A缺乏的一个指标，在这群孕妇和哺乳期妇女中似乎是一个问题，可能会对妇女及其婴儿的健康产生影响。
