Adequate nutrient intakes among women of reproductive age (WRA) are important determinants of maternal, neonatal and child health outcomes. However, data on dietary intake for WRA in Vietnam are lacking. This paper aimed to examine the adequacy and determinants of energy and macronutrient intakes among WRA enrolled in a study of preconceptual micronutrient supplementation (PRECONCEPT) being conducted in 20 rural communes in Thai Nguyen province, Vietnam.
Dietary intakes were determined for 4983 WRA who participated in the baseline survey using a previously validated 107-item (semi-quantitative) food-frequency questionnaire that was administered by trained field workers. Multivariate linear and logistic regression analyses were used to examine factors associated with energy and macronutrient intakes.
A disproportionate number of energy came from starches, primarily rice. Carbohydrate, fat and protein constituted 65.6%, 19.5% and 14.8% of total energy, respectively. Fat intake was below recommended levels in 56.5% of respondents, but carbohydrate intakes were above recommended level in 54.6%. Only 0.1% and 5.2% of WRA achieved adequate intake of n-3 and n-6 long-chain polyunsaturated fatty acids, respectively. Multivariate linear regression revealed that low education, low socioeconomic status, and food insecurity were significant predictors of reduced total energy intake, reduced energy from protein and fat, and greater energy from carbohydrates. Logistic regression confirmed that inadequate macronutrient intake was more common among the poor, food insecure, and less educated.
Imbalanced dietary intakes among underprivileged women reflect lack of dietary diversity. Nutrition programs should be linked with social development, poverty reduction, education programs and behavior change counseling in order to improve the nutritional status of WRA in Vietnam.
育龄妇女充足的营养素摄入是孕产妇、新生儿及儿童健康状况的重要决定因素。然而,越南育龄妇女的饮食摄入数据匮乏。本文旨在研究参与越南太原省20个农村公社开展的孕前微量营养素补充研究(PRECONCEPT)的育龄妇女能量和宏量营养素摄入的充足性及其决定因素。
对参与基线调查的4983名育龄妇女,采用经过先前验证的由经过培训的现场工作人员发放的107项(半定量)食物频率问卷来确定其饮食摄入量。使用多变量线性和逻辑回归分析来研究与能量和宏量营养素摄入相关的因素。
能量来源中淀粉类食物占比过高,主要是大米。碳水化合物、脂肪和蛋白质分别占总能量的65.6%、19.5%和14.8%。56.5%的受访者脂肪摄入量低于推荐水平,但54.6%的受访者碳水化合物摄入量高于推荐水平。分别只有0.1%和5.2%的育龄妇女达到了n-3和n-6长链多不饱和脂肪酸的充足摄入量。多变量线性回归显示,低教育水平、低社会经济地位和粮食不安全是总能量摄入减少、蛋白质和脂肪能量减少以及碳水化合物能量增加的显著预测因素。逻辑回归证实,宏量营养素摄入不足在贫困人口、粮食不安全人群和受教育程度较低者中更为常见。
贫困妇女饮食摄入不均衡反映出饮食多样性不足。营养项目应与社会发展、减贫、教育项目及行为改变咨询相结合,以改善越南育龄妇女的营养状况。
