Entertainment education and the promotora model are 2 evidence-based health communication strategies. This study examined their combined effect on promoting healthy eating among mothers in a family-based intervention. Participants were 361 Mexican-origin families living in Imperial County, California, who were randomly assigned to an intervention or delayed treatment condition. The intervention involved promotoras (community health workers) who delivered 11 home visits and 4 telephone calls. Home visits included a 12-minute episode of a 9-part situation comedy depicting a family struggling with making healthy eating choices; an accompanying family workbook was reviewed to build skills and left with the family. Baseline and immediate postintervention data were collected from the mothers, including the primary outcome of daily servings of fruits and vegetables. Other dietary and psychosocial factors related to healthy eating were examined. At postintervention, mothers in the intervention reported increases in daily vegetable servings (p ≤ .05); however, no changes were observed in fruit consumption. Improvements were observed in behavioral strategies to increase fiber (p ≤ .001) and to decrease fat intake (p ≤ .001), unhealthy eating behaviors (p ≤ .001), and individual (p ≤ .05) and family-related (p ≤ .01) perceived barriers to healthy eating. Entertainment education and promotoras engaged families and improved mothers' diets. Further research should examine the dose needed for greater changes.
娱乐教育和推广者模式是两种基于证据的健康传播策略。本研究在一项基于家庭的干预措施中,考察了它们对促进母亲健康饮食的综合效果。研究对象为居住在加利福尼亚州帝国县的361个墨西哥裔家庭,这些家庭被随机分配到干预组或延迟治疗组。干预措施包括由推广者(社区卫生工作者)进行11次家访和4次电话随访。家访内容包括一部9集情景喜剧的12分钟剧集,该剧描绘了一个在做出健康饮食选择方面苦苦挣扎的家庭;同时还会查看一本配套的家庭工作手册,以培养相关技能并留给家庭。从母亲们那里收集了基线数据和干预后即时数据,包括水果和蔬菜每日摄入量这一主要结果。还考察了与健康饮食相关的其他饮食和心理社会因素。干预后,干预组的母亲报告称每日蔬菜摄入量有所增加(p≤0.05);然而,水果摄入量未观察到变化。在增加纤维摄入量(p≤0.001)、减少脂肪摄入量(p≤0.001)、不健康饮食行为(p≤0.001)以及个人(p≤0.05)和家庭相关(p≤0.01)的健康饮食感知障碍方面均观察到了改善。娱乐教育和推广者模式让家庭参与其中并改善了母亲的饮食。进一步的研究应考察实现更大变化所需的剂量。
