This study was done to develop a pregnancy nutrition knowledge scale and to examine the relationships between pregnancy nutrition knowledge and eating habits in pregnant women.
With convenient sampling, 189 pregnant women who used community health centers for their ante-natal care were recruited. Data were collected using a self administered questionnaire including items on pregnancy nutrition knowledge (18 items) developed by researcher and items on eating habits (14 items). Cronbach's alpha and exploratory factor analysis were examined to test reliability and construct validity of the scale. Pearson's correlation coefficients were used to identify the relationship between pregnancy nutrition knowledge and eating habits.
Cronbach's alpha of 18 items was .80. In factor analysis using principal components, 6 factors explained 65% of the total variance. The level of pregnancy nutrition knowledge was not sufficient but correlations between pregnancy nutrition knowledge and some of eating habits were significant. Specifically, pregnancy nutrition knowledge was positively correlated with good eating habits and negatively with bad eating habits.
The pregnancy nutrition knowledge scale developed in this study is acceptable for nutrition education led by nurses. Pregnancy nutrition knowledge and eating habits are considered as major variables for ante-natal nutrition education. In future studies, explorations are needed on dietary intake and physiological indices in pregnant women, comparison of women at risk with those not at risk, and development of nutritional education programs for pregnant women.
本研究旨在开发一种孕期营养知识量表,并探讨孕妇孕期营养知识与饮食习惯之间的关系。
采用方便抽样法,招募了189名在社区卫生中心进行产前检查的孕妇。使用自编问卷收集数据,问卷包括研究者编制的孕期营养知识项目(18项)和饮食习惯项目(14项)。通过检验克朗巴哈系数和探索性因子分析来测试量表的信度和结构效度。使用皮尔逊相关系数来确定孕期营养知识与饮食习惯之间的关系。
18个项目的克朗巴哈系数为0.80。在主成分因子分析中,6个因子解释了总方差的65%。孕期营养知识水平不足,但孕期营养知识与部分饮食习惯之间的相关性显著。具体而言,孕期营养知识与良好饮食习惯呈正相关,与不良饮食习惯呈负相关。
本研究开发的孕期营养知识量表可用于护士主导的营养教育。孕期营养知识和饮食习惯被视为产前营养教育的主要变量。在未来的研究中,需要对孕妇的饮食摄入量和生理指标进行探索,对有风险的女性与无风险的女性进行比较,并为孕妇制定营养教育计划。
