Shared plate eating (SPE), defined as two or more individuals eating directly from the same plate or bowl, is a common household food consumption practice in many Low- and Middle-Income Countries (LMICs). Examination of household engagement in SPE remains largely unexplored, highlighting a gap in research when interpreting dietary information obtained from these settings. The dearth of research into SPE can be attributed to the inherent limitations of traditional dietary assessment methods which constrain their usability in settings where SPE is common.
In this expository narrative, we describe what SPE is when it is practiced in an LMIC such as Ghana; and also compare the frequency of SPE versus individual plate eating (IPE) by different household members in rural and urban households using a wearable camera (Automatic Ingestion Monitor version 2: AIM-2).
Purposive convenience sampling was employed to recruit and enroll 30 households each from an urban and a rural community ( = 60 households) in Ghana. The AIM-2 was worn on eyeglass frames for 3 days by selected household members. The AIM-2, when worn, automatically collects images to capture food consumption in participants' environments, thus enabling passive capture of household SPE dynamics.
A higher percentage of SPE occasions was observed for rural (96.7%) compared to urban (36.7%) households ( < 0.001). Common SPE dynamics included only adults sharing, adults and children sharing, only children sharing, and non-household member participation in SPE.
The wearable camera captured eating dynamics within households that would have likely been missed or altered by traditional dietary assessment methods. Obtaining reliable and accurate data is crucial for assessing dietary intake in settings where SPE is a norm.
共盘进食（SPE）被定义为两个或更多人直接从同一个盘子或碗中取食，这是许多低收入和中等收入国家（LMICs）常见的家庭食物消费行为。家庭共盘进食行为的研究在很大程度上仍未得到充分探索，这凸显了在解释从这些环境中获得的饮食信息时的研究空白。对共盘进食研究的匮乏可归因于传统饮食评估方法的固有局限性，这些局限性限制了它们在共盘进食普遍存在的环境中的可用性。
在这篇说明性叙述中，我们描述了在加纳等低收入和中等收入国家实行的共盘进食是什么样的；并且还使用可穿戴摄像头（自动摄入监测器第2版：AIM-2）比较了农村和城市家庭中不同家庭成员共盘进食与分盘进食（IPE）的频率。
采用目的便利抽样法，从加纳的一个城市社区和一个农村社区各招募并纳入30户家庭（n = 60户）。选定的家庭成员将AIM-2戴在眼镜框上3天。佩戴AIM-2时，它会自动收集图像，以捕捉参与者环境中的食物消费情况，从而能够被动捕捉家庭共盘进食动态。
观察到农村家庭（96.7%）的共盘进食情况比例高于城市家庭（36.7%）（P < 0.001）。常见的共盘进食动态包括只有成年人共享、成年人与儿童共享、只有儿童共享以及非家庭成员参与共盘进食。
可穿戴摄像头捕捉到了家庭内部的进食动态，而这些动态很可能会被传统饮食评估方法遗漏或改变。在共盘进食成为常态的环境中，获取可靠准确的数据对于评估饮食摄入量至关重要。
