Portable systems using three-dimensional (3D) scan data to calculate young child anthropometry measurements in population-based surveys and surveillance systems lack acceptability data from field workers and caregivers.
The aim was to assess acceptability and experiences with 3D scans measuring child aged 0-59 mo anthropometry in population-based surveys and surveillance systems in Guatemala, Kenya, and China (0-23 mo only) among field teams and caregivers of young children as secondary objectives of an external effectiveness evaluation.
Manual data were collected twice and 12 images captured per child by anthropometrist/expert and assistant (AEA) field teams (individuals/country, = 15/Guatemala, = 8/Kenya, = 6/China). Caregivers were interviewed after observing their child's manual and scan data collection. Mixed methods included an administered caregiver interview (Guatemala, = 465; Kenya, = 496; China, = 297) and self-administered AEA questionnaire both with closed- and open-ended questions, and 6 field team focus group discussions (FGDs; Guatemala, = 2; Kenya, = 3; China, = 1). Qualitative data were coded by 2 authors and quantitative data produced descriptive statistics. Mixed-method results were compared and triangulated.
Most AEAs were female with secondary or higher education. Approximately 80-90% of caregivers were the child's mother. To collect all anthropometry data, 62.1% of the 29 AEAs preferred scan, while 31% preferred manual methods. In FGDs, a key barrier for manual and scan methods was lack of child cooperation. Across countries, approximately 30% to almost 50% of caregivers said their child was bothered by each manual and scan method, while ≥95% of caregivers were willing to have their child measured by scans in the future.
Use of 3D scans to calculate anthropometry measurements was generally at least as acceptable as manual anthropometry measurement among AEA field workers and caregivers of young children aged <60 mo, and in some cases preferred.
在基于人群的调查和监测系统中，使用三维（3D）扫描数据来计算幼儿人体测量数据的便携式系统缺乏来自现场工作人员和照料者的可接受性数据。
作为一项外部有效性评估的次要目标，评估危地马拉、肯尼亚和中国（仅0 - 23个月）基于人群的调查和监测系统中，现场团队和幼儿照料者对测量0 - 59个月儿童人体测量的3D扫描的可接受性和体验。
人体测量师/专家及助手（AEA）现场团队（每个国家的人数分别为：危地马拉15人、肯尼亚8人、中国6人）对每个儿童手动收集两次数据并拍摄12张图像。在观察其孩子的手动和扫描数据收集后，对照料者进行访谈。混合方法包括一份对照料者进行的访谈（危地马拉465人、肯尼亚496人、中国297人）以及一份AEA自我填写的问卷，二者均包含封闭式和开放式问题，还有6次现场团队焦点小组讨论（FGD；危地马拉2次、肯尼亚3次、中国1次）。定性数据由两名作者进行编码，定量数据生成描述性统计。对混合方法的结果进行比较和三角互证。
大多数AEA是女性，具有中学或更高学历。大约80 - 90%的照料者是孩子的母亲。为收集所有人体测量数据，29名AEA中有62.1%更喜欢扫描，而31%更喜欢手动方法。在焦点小组讨论中，手动和扫描方法的一个关键障碍是儿童不配合。在各个国家，大约30%至近50%的照料者表示他们的孩子对每种手动和扫描方法都感到困扰，而≥95%的照料者愿意让他们的孩子在未来接受扫描测量。
对于＜60个月幼儿的AEA现场工作人员和照料者而言，使用3D扫描来计算人体测量数据通常至少与手动人体测量一样可接受，在某些情况下更受青睐。
