摘要

The riboflavin nutritional status of 128 pregnant women in the central part of Taiwan was evaluated by determining their glutathione reductase activity coefficient (AC). Twenty four-hours dietary recalls method was also performed in order to obtain supplementary information for the evaluation.
The overall average AC value among the pregnant women was 1.26. The mean AC value for urban pregnant women was only 1.21 compared with 1.30 for rural pregnant women. 45.1% of the urban women had AC values greater than 1.20 and 11.8% had values greater than 1.40, whereas 58.5% of the rural women had AC values greater than 1.20 and 32.5% of them greater than 1.40. Thus, the urban pregnant women appeared to have better riboflavin nutriture than the rural women.
It was further evaluated whether the greater AC values were related to trimester of pregnancy, the number of previous pregnancies, educational status and economic condition. Although no significant difference was found related to trimester of pregnancy, the AC value was found to increase with each trimester. The incidence was higher among educationally deprived group and the low income group.
The lower riboflavin intakes were also found in rural area compared with urban area (0.9mg/day vs. 1.1mg/day). This is in agreement with the AC value we obtained in this research.
