An intervention program was undertaken to assess dietary habits and the impact of nutrition education among pregnant women in the rural county of Florina, northern Greece. Analysis of dietary habits, nutrient intake, hemoglobin, and serum vitamin concentrations in an intervention and control group indicated that the population was adequately nourished although nutrient intake was below recommended levels for pregnant women. Nutrition counseling was associated with improvements in dietary intake and significantly greater maternal weight gain (p less than 0.05). Mean birth weight was slightly higher in the intervention group but so was the incidence of low birth weight (4.5% vs 3.9%). The prematurity rate was marginally lower in the intervention group (p less than 0.04), as was the number of perinatal deaths (9 vs 11). The results indicate that nutrition counseling during pregnancy can improve dietary intake and maternal weight gain but the mediating influence on low frequency pregnancy outcomes is indeterminate in a population that is not nutritionally at risk.
在希腊北部弗洛里纳县的农村地区，开展了一项干预项目，以评估孕妇的饮食习惯以及营养教育的影响。对干预组和对照组的饮食习惯、营养素摄入量、血红蛋白和血清维生素浓度进行分析后发现，尽管营养素摄入量低于孕妇的推荐水平，但该人群营养状况良好。营养咨询与饮食摄入量的改善以及孕妇体重显著增加有关（p小于0.05）。干预组的平均出生体重略高，但低出生体重的发生率也较高（4.5%对3.9%）。干预组的早产率略低（p小于0.04），围产期死亡人数也较少（9例对11例）。结果表明，孕期营养咨询可改善饮食摄入量和孕妇体重增加，但对于一个不存在营养风险的人群，其对低发生率妊娠结局的介导影响尚不确定。
