The Internet offers a valuable resource for promotion of healthy eating and Web-based communication between the dietetics practitioner and client. In a 16-week intervention examining the effects of energy restriction (500 kcal/day) and exercise on body composition in overweight/obese lactating women, MyPyramid Menu Planner for Moms was used to support dietary counseling. Random assignment occurred at 4 weeks postpartum to either an Intervention group (n=14) or Minimal Care group (n=13) from 2008 through 2010. Three 24-hour dietary recalls were obtained using the Nutrition Data System at 4 and 20 weeks postpartum. Individual MyPyramid Menu Planner accounts were created for the Intervention group and used in face-to-face dietary counseling. Repeated measures analysis of variance was used to test for differences between groups for change in dietary intake and weight. Changes in energy, saturated fat, and percent of energy from added sugars were significantly different between Intervention group and Minimal Care group (-613 [521] kcal vs -171 [435] kcal; P=0.03; -14.9 [14.0] g vs +0.9 [13.4] g; P<0.01; and -3.5% [5.3%] vs +2.2% [4.8%]; P<0.01, respectively). The Intervention group significantly increased their whole fruit servings and decreased their total grain and milk servings compared with the Minimal Care group (P<0.05). The Intervention group lost significantly more weight (-5.8 [3.5] kg) than the Minimal Care group (-1.6 [5.4] kg) (P=0.03). Although participants must have access to an Internet-based computer and possess basic food knowledge, these results suggest MyPyramid Menu Planner might prove to be an effective dietary counseling support tool for improving dietary intake and promoting weight loss during lactation.
互联网为促进健康饮食以及营养学家与客户之间的网络交流提供了有价值的资源。在一项为期 16 周的干预研究中，研究人员检查了能量限制（每天 500 卡路里）和锻炼对超重/肥胖哺乳期妇女身体成分的影响，在该研究中使用了 MyPyramid 孕妇食谱规划器来支持饮食咨询。2008 年至 2010 年期间，从产后 4 周开始，将参与者随机分配到干预组（n=14）或最低护理组（n=13）。在产后 4 周和 20 周时，使用营养数据系统获得了 3 次 24 小时饮食记录。为干预组创建了个人 MyPyramid 食谱规划器账户，并在面对面的饮食咨询中使用。使用重复测量方差分析来检验两组之间的饮食摄入和体重变化差异。干预组和最低护理组的能量、饱和脂肪和添加糖的能量百分比的变化差异有统计学意义（-613[521]kcal 与-171[435]kcal；P=0.03；-14.9[14.0]g 与+0.9[13.4]g；P<0.01；和-3.5%[5.3%]与+2.2%[4.8%]；P<0.01）。与最低护理组相比，干预组的全水果摄入量显著增加，而总谷物和牛奶摄入量显著减少（P<0.05）。与最低护理组相比，干预组的体重明显减轻（-5.8[3.5]kg），而最低护理组的体重减轻了（-1.6[5.4]kg）（P=0.03）。尽管参与者必须具备使用基于互联网的计算机的条件，并且具备基本的食物知识，但这些结果表明，MyPyramid 孕妇食谱规划器可能被证明是一种有效的饮食咨询支持工具，可用于改善哺乳期的饮食摄入和促进体重减轻。
