研究小规模人群中的幼儿生长对于了解人类生活史变异和通过全球公共卫生倡议增强为这些社区服务的能力至关重要。本研究描述了幼儿生长轨迹，并确定了Daasanach半游牧牧民儿童生活在炎热，干旱地区的北方Keny.MethodsA大样本的身高和体重的措施，从儿童（N= 1756;总观察值= 4508;年龄= 0-5岁）之间的国际参考之间的生长模式的差异收集2018年和2020年。Daasanach的增长进行了比较，国际参考标准和Daasanach特定的百分位数的增长曲线和伪速度模型使用广义加法模型的位置规模和size.ResultsCompared世界卫生组织（WHO）的参考，相对较少的Daasanach儿童发育迟缓（14.3%），而很大一部分体重不足（38.5%）和浪费（53.6%）。此外，Daasanach儿童有一种独特的生长模式，其特征是24个月后线性生长速度增加，并且在幼儿期其余时间内线性生长速度相对较高。结论这些结果发现了小规模人群中儿童早期生长停滞的独特模式，可能反映了他们对炎热、干旱环境的体温调节适应。由于线性生长和体重增加仍然是健康的重要指标，这项研究的结果提供了对生长速度变化的见解。这项研究对全球公共卫生工作具有重要意义，以确定和解决小规模人群中早期生长迟缓和营养不良的来源。
ObjectivesInvestigations of early childhood growth among small‐scale populations are essential for understanding human life history variation and enhancing the ability to serve such communities through global public health initiatives. This study characterizes early childhood growth trajectories and identifies differences in growth patterns relative to international references among Daasanach semi‐nomadic pastoralist children living in a hot, arid region of northern Kenya.MethodsA large sample of height and weight measures were collected from children (N= 1756; total observations = 4508; age = 0–5 years) between 2018 and 2020. Daasanach growth was compared to international reference standards and Daasanach‐specific centile growth curves and pseudo‐velocity models were generated using generalized additive models for location scale and size.ResultsCompared to World Health Organization (WHO) reference, relatively few Daasanach children were stunted (14.3%), while a large proportion were underweight (38.5%) and wasted (53.6%). Additionally, Daasanach children had a distinctive pattern of growth, marked by an increase in linear growth velocity after 24 months of age and relatively high linear growth velocity throughout the rest of early childhood.ConclusionsThese results identify a unique pattern of early childhood growth faltering among children in a small‐scale population and may reflect a thermoregulatory adaptation to their hot, arid environment. As linear growth and weight gain remain important indicators of health, the results of this study provide insight into growth velocity variations. This study has important implications for global public health efforts to identify and address sources of early growth faltering and undernutrition in small‐scale populations.
