先前关于家庭用餐环境的研究表明，家庭用餐与儿童和青少年的积极健康结果有关。研究人员已经开始使用直接观察的方法来了解家庭用餐的关键方面，如用餐的健康程度和家庭用餐的频率，以解释家庭用餐的保护性质。然而，直接观测研究可能会耗费大量资源，也会给参与者带来负担。需要使用直接观察性研究方法提供有关充分描述典型膳食健康特征所需天数的信息。目前的研究旨在通过对家庭食物环境的直接观察、混合方法研究，制定关于在家庭聚餐场合接近典型膳食健康所需的膳食数量的指导意见。家庭在2012-2013年间从明尼阿波利斯-圣保罗大都市区的初级保健诊所招募(N=120)。作为家庭聚餐活动的一部分，总共收集了800顿饭！混合方法研究。采用膳食健康指数评价8个家庭用餐场合的膳食健康状况。参与的家庭获得了一台iPad(苹果公司)，并被要求对连续8天的家庭聚餐进行视频记录，其中至少有两顿周末聚餐。用餐后，家庭完成用餐筛查，这是一种自我报告的、无限制的衡量用餐时提供的食物的指标。周末和工作日的用餐在衡量膳食健康程度方面有所不同，这表明至少有一个工作日和一个周末是接近膳食健康所必需的。单日测量将提供的食物的质量和摄入量之间的关系的强度错误地描述了近50%，而3到4个观察日足以表征典型的每周膳食健康(r=0.94；P<；.001)。相对较少的家庭用餐直接观测天数数据似乎需要在一周内近似估计用餐的健康程度。具体地说，需要1个工作日和1个周末的观测，包括总共3至4天的直接观测膳食数据。这些发现可能会为未来的直接观察性研究设计提供参考，以减少研究成本和参与者在评估饮食环境特征方面的负担。
Prior research around the home meal environment has demonstrated that family meals are associated with positive health outcomes for children and adolescents. Researchers have begun using direct observational methods to understand key aspects of family meals such as meal healthfulness and family meal frequency to explain the protective nature of family meals. Direct observational research, however, can be resource intensive and also burdensome for participants. Information about the number of days needed to sufficiently characterize typical meal healthfulness using direct observational research methods is needed. The current study aimed to produce guidance about the number of meals necessary to approximate typical meal healthfulness at the family dinner meal occasion in a direct observational, mixed methods study of the home food environment. Families were recruited between 2012-2013 from primary care clinics in the Minneapolis–St Paul metropolitan area (N=120). A total of 800 meals were collected as part of the Family Meals LIVE! mixed methods study. The Healthfulness of Meal Index was used to evaluate meal dietary healthfulness of foods served at 8 family meal occasions. Participating families were provided an iPad (Apple Inc) and asked to video-record 8 consecutive days of family dinner meals with a minimum of two weekend meals. After the meal, families completed a meal screener, which is a self-reported, open-ended measure of the foods served at the meal. Weekend and weekday meals differed in their measurement of meal healthfulness, indicating that at least one weekday and one weekend day are necessary to approximate meal healthfulness. Single-day measurement mischaracterized the strength of the relationship between the quality of what was served and intake by almost 50%, and 3 to 4 observation days were sufficient to characterize typical weekly meal healthfulness (r=0.94; P<.001). Relatively few direct observational days of family meals data appear to be needed to approximate the healthfulness of meals across 1 week. Specifically, 1 weekday and 1 weekend observation are needed, including a total of 3 to 4 days of direct observational meal data. These findings may inform future direct observational study designs to reduce both research costs and participant burden in assessing features of the meal environment.
