Abstract

Objective

To compare the changes in children's height, weight, and BMI from two Maya communities during 1986–2023 in order to analyze if their differences in degrees of participation in market economy are reflected in secular changes in growth measures.

Material and Methods

We compared the changes in height, weight, and BMI of 1463 children (6–12 years) from two communities (Dzeal and Yalcoba) differing by speed and degree of market integration along three points in time: 1986/1987, 1996–1998/2000 and 2022/2023. Linear regression models were adjusted to estimate the changes in height-for-age (HAZ) and BMI-for-age Z-scores (BMIZ) in each community by age group and sex using the period of measurement as the independent variable.

Results

Increases in HAZ between 1986/1987 and 2022/2023 were greater in children from the community with slower integration into the market economy (Dzeal). Differences in total increases between 1986/1987 and 2022/2023 in HAZ between communities were 0.50 (boys) and 1.19 (girls) standard deviations (SD) score in the 6–8-year-old group and 0.40 (boys) and 0.41 SD (girls) in children aged 9–12. Total increases in BMIZ were 0.81 SD (boys) and 1.07 SD (girls) in children (6–8 years) from the community with rapid integration (Yalcoba); changes in children with slower integration were not significant.

Conclusion

The rapid integration of the community into the market economy seems to favor larger secular increases in children's BMI and smaller increases in linear growth.

墨西哥尤卡坦半岛两个玛雅社区的市场整合和人体测量特征的长期变化

目的比较1986-2023年两个玛雅社区儿童身高、体重和BMI的变化，分析其参与市场经济程度的差异是否反映在生长指标的长期变化上。材料和方法我们比较了来自两个社区（Dzeal和Yalcoba）的1463名6-12岁儿童（6-12岁）的身高、体重和BMI的变化，这些儿童在1986/1987年、1996-1998/2000年和2022/2023年三个时间点的市场一体化速度和程度不同。调整线性回归模型，以测量期为自变量，按年龄和性别估计各社区身高年龄比（HAZ）和体重年龄比z得分（BMIZ）的变化。结果1986/1987年和2022/2023年期间，HAZ在融入市场经济较慢的社区儿童中增加较多。1986/1987年和2022/2023年社区间HAZ总增加值的差异为：6 - 8岁组男孩0.50和女孩1.19标准差（SD）， 9-12岁组男孩0.40和女孩0.41标准差（SD）。来自快速整合社区（Yalcoba）的6-8岁儿童BMIZ总增加为0.81 SD（男孩）和1.07 SD（女孩）；在整合较慢的儿童中变化不显著。结论社区与市场经济的快速融合似乎有利于儿童BMI的较大长期增长和较小的线性增长。

期刊介绍： The American Journal of Human Biology is the Official Journal of the Human Biology Association. The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field. The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology. Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification. The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
