【摘要】：目的研究孕妇饮食行为及其影响因素。方法对624名早期妊娠孕妇、619名中期妊娠孕妇及738名晚期妊娠孕妇进行饮食行为问卷调查研究。结果被调查的孕妇年龄18~45岁,74%的孕妇体质量指数(BMI)在正常范围,超过43%的孕妇由母亲照顾,其次是丈夫。在合理营养方面,妊娠各期孕妇碳水化合物、脂肪和蛋白质摄入与推荐值比较,差异无统计学意义(P0.05)。在食物选择上,妊娠中晚期进食谷类、奶类、水产品、豆类量不足,各期进食水果、坚果过多(P0.05)。结构方程模型分析结果显示,主观行为规范并不直接影响膳食行为,而是通过对行为态度及行为意向的影响间接影响孕妇的膳食行为,标准化回归系数分别为0.245(P=0.000)和0.718(P=0.000)。结论研究对象的膳食行为较好,但在食物的选择和合理搭配上存在问题,特别是水果进食过多。主观行为规范通过对行为态度及行为意向的影响间接影响孕妇的膳食行为,与孕妇直接接触的人中,孕妇的母亲对其膳食态度和行为意向的影响最明显。
[Abstract]:Objective to study the dietary behavior of pregnant women and its influencing factors. Methods A questionnaire survey was conducted among 624 pregnant women in early pregnancy, 619 pregnant women in the middle trimester and 738 pregnant women in the third trimester of pregnancy. Results the age of the surveyed pregnant women was 18 times 45 years old. 74% of the pregnant women had a body mass index (BMI) in the normal range, more than 43% of the pregnant women were cared for by their mothers, followed by their husbands. In terms of reasonable nutrition, there was no significant difference in carbohydrate, fat and protein intake between pregnant women and recommended values (P 0.05). In food selection, eating cereals, milk, aquatic products, beans in the third trimester of pregnancy, eating fruit and nuts in each stage (P 0.05). The results of structural equation model analysis showed that the subjective behavior norm did not directly affect the dietary behavior, but indirectly affected the dietary behavior of pregnant women through the influence of behavior attitude and behavior intention. The standardized regression coefficients were 0.245 (P 鈮，
