目的了解云南省建水县农村育龄妇女叶酸服用情况及其影响因素,为提高叶酸干预效果提供科学依据。方法采用整群抽样的方法,选取云南省建水县2014年1-12月产生妊娠结局并建立健康档案的2 680名农村妇女作为研究对象。结果叶酸正确开始服用率为33.80%,经多因素Logistic回归分析显示,年龄越大(OR=1.03,95%CI:1.01~1.06)、末次月经准确(OR=3.41,95%CI:1.61~7.23)的育龄妇女叶酸正确开始服用率越高;叶酸规律服用率为90.07%,经多因素Logistic分析显示,年龄越大(OR=1.07,95%CI:1.04~1.10)、无不良妊娠史(OR=1.45,95%CI:1.11~1.89)、末次月经准确(OR=3.18,95%CI:2.08~4.86)的农村育龄妇女叶酸规律服用率越高。结论云南省建水县农村育龄妇女正确开始服用叶酸率较低,规律服用率较高;年龄越大、末次月经准确者叶酸正确开始服用率及规律服用率越高;无不良妊娠史的农村育龄妇女叶酸规律服用率越高。
Objective To understand the situation of folic acid intake and its influencing factors among rural women of childbearing age in Jianshui County, Yunnan Province, and to provide a scientific basis for improving the effect of folic acid intervention. Methods A cluster sampling method was used to select 2 680 rural women who had a pregnancy outcome and a health record from January to December 2014 in Jianshui County, Yunnan Province. Results The correct rate of folic acid intake was 33.80%. Multivariate Logistic regression analysis showed that the older the age was (OR = 1.03, 95% CI: 1.01-1.06), the last menstrual period was accurate (OR = 3.41, 95% CI: 1.61-7.23 (OR = 1.07, 95% CI: 1.04 ~ 1.10), no history of adverse pregnancy (OR = 1.07, 95% CI: 1.04 ~ 1.10), and the rate of folic acid intake was 90.07% .The multivariate Logistic analysis showed that the age = 1.45, 95% CI: 1.11-1.89). The higher the prevalence of folic acid in rural women of childbearing age with the last menstruation (OR = 3.18,95% CI: 2.08-4.86) Conclusions The incidence rate of folic acid in rural women of child-bearing age in Jianshui County of Yunnan Province is relatively low, and the regular taking rate is higher. The older the age, the correct taking of folic acid in the last menstruation and the regular taking rate are higher; Women folic acid law taking the higher rates.
