摘要

目的这项研究旨在分析环境变化对经历快速工业化的墨西哥皮马人的身体成分、总能量消耗和体力活动的影响：我们使用双标记水，比较了 1995 年和 2010 年墨西哥皮马人（n = 26；女性：12）的纵向队列中的能量消耗和体力活动。通过生物阻抗分析评估了身体质量和组成。为了确定环境因素对体重的影响与年龄无关，我们将 1995 年的纵向队列与 2010 年年龄和性别匹配的横截面队列（n = 26）进行了比较：结果：1995 年至 2010 年间，体重、脂肪量和无脂肪量均显著增加。尽管体重平均增加了 13%，但体重调整后的每日总能量消耗却大幅下降。在对体重进行调整后，1995 年至 2010 年间测量的体力活动水平也有所下降：我们的研究结果表明，墨西哥索诺拉州梅科巴地区最近的工业化导致体力活动减少，进而导致墨西哥皮马人体重增加和代谢性疾病。

Changes in energy expenditure and physical activity over 15 years of environmental changes: The Maycoba project

Objective

This work aimed to parse out the role of changing environments on body composition, total energy expenditure, and physical activity in the Mexican Pima, a population experiencing rapid industrialization.

Methods

Using doubly labeled water, we compared energy expenditure and physical activity in a longitudinal cohort of Mexican Pima (n = 26; female: 12) in 1995 and 2010. Body mass and composition were assessed by bioimpedance analysis. To determine the effects of environmental factors on body weight independent of age, we compared the 1995 longitudinal cohort with an age- and sex-matched cross-sectional cohort (n = 26) in 2010.

Results

Body mass, fat mass, and fat-free mass all significantly increased between 1995 and 2010. Despite a 13% average increase in body weight, weight-adjusted total daily energy expenditure decreased significantly. Measured physical activity levels also decreased between 1995 and 2010, after we adjusted for weight.

Conclusions

Our results suggest that the recent industrialization of the Maycoba region in Sonora, Mexico, has contributed to a decrease in physical activity, in turn contributing to weight gain and metabolic disease among the Mexican Pima.
