This study examined the effects of a nutrition education intervention on improving the intake and behaviors related to whole grain foods in congregate meal recipients in senior centers in north Georgia. Participants were a convenience sample and completed a pretest, an educational intervention, and a post-test (N = 84, mean age = 77 years, 88% female, 76% Caucasian, and 24% African American). At the pre-test, most participants agreed that eating more whole grain foods would help reduce their risk of cancer (69%), heart disease (76%), type 2 diabetes (65%), and bowel disorders (82%), but consumption of 11 whole grain foods was low (10.5 times/week). Following the intervention, participants were more likely to suggest one or more correct ways to identify whole grain foods (45 vs. 62%, P< or = 0.05), and to report an increased intake of whole grain bread, cereal, and crackers (5.8 vs. 6.9 times/week, P < or = 0.05). While awareness of the health benefits of whole grain foods was high, the intakes were low. As a first step, this intervention improved several aspects of the consumption of whole grain foods; however, additional interventions that target the individual and the congregate meal program are needed to increase intakes to the recommended three servings daily.
本研究调查了营养教育干预对改善佐治亚州北部老年中心集体用餐者全谷物食品摄入量及相关行为的影响。参与者为便利样本,完成了一项预测试、一次教育干预和一次后测试(N = 84,平均年龄 = 77岁,88%为女性,76%为白种人,24%为非裔美国人)。在预测试中,大多数参与者认为多吃全谷物食品有助于降低患癌症(69%)、心脏病(76%)、2型糖尿病(65%)和肠道疾病(82%)的风险,但11种全谷物食品的摄入量较低(每周10.5次)。干预后,参与者更有可能提出一种或多种正确识别全谷物食品的方法(45%对62%,P≤0.05),并报告全谷物面包、谷物和饼干的摄入量有所增加(每周5.8次对6.9次,P≤0.05)。虽然对全谷物食品健康益处的认知度较高,但摄入量较低。作为第一步,该干预改善了全谷物食品消费的几个方面;然而,需要针对个人和集体用餐计划的额外干预措施,以将摄入量提高到建议的每日三份。
