This paper demonstrates that although modern BMIs in the US have increased, 19th century BMIs in Philadelphia were lower than elsewhere within Pennsylvania, indicating that urbanization and agricultural commercialization were associated with lower BMIs. After controlling for stature, blacks consistently had greater BMI values than mulattos and whites; therefore, there is no evidence of a 19th century mulatto BMI advantage in the industrializing North. Farmers' BMIs were consistently heavier than those of non-farmers.
本文表明，尽管美国现代 BMI 指数有所上升，但 19 世纪费城的 BMI 指数却低于宾夕法尼亚州的其他地区，这表明城市化和农业商业化与较低的 BMI 指数有关。控制身高后，黑人的 BMI 值始终高于黑白混血儿和白人；因此，在工业化的北方，没有 19 世纪黑白混血儿 BMI 优势的证据。农民的 BMI 指数始终高于非农民。
