To describe bone mineral density (BMD) at the hip and spine and prevalence of low bone mass and osteoporosis in Navajo men and women across age, gender, and body mass index (BMI) compared with non-Hispanic (NH) Whites from NHANES (2005-2008).
Cross-sectional dual energy x-ray absorptiometry measurements at the hip and spine in 1,097 participants from the Education and Research Towards Health study.
Bone mineral density was lower among younger Navajo than NH-Whites at lower BMI, and in overweight, younger men at lumbar spine and total hip. Spine BMD was lower in Navajo women, across BMI. Prevalence of low bone mass and osteoporosis in Navajo was higher than NH-Whites, particularly among women.
Further research is needed to understand if lower BMD among younger Navajo signals a risk for future fracture, and fracture risk relative to BMD, given the challenges in health care access and fracture morbidity among minorities.
描述纳瓦霍族男性和女性在不同年龄、性别和体重指数（BMI）情况下，髋部和脊柱的骨矿物质密度（BMD）以及低骨量和骨质疏松症的患病率，并与来自美国国家健康与营养检查调查（NHANES，2005 - 2008年）的非西班牙裔（NH）白人进行比较。
对来自“健康研究与教育”研究的1097名参与者进行髋部和脊柱的横断面双能X线吸收测定。
在较低BMI时，较年轻的纳瓦霍族人的骨矿物质密度低于非西班牙裔白人，且在超重的较年轻男性中，腰椎和全髋部的骨矿物质密度也较低。在所有BMI水平下，纳瓦霍族女性的脊柱骨矿物质密度均较低。纳瓦霍族人中低骨量和骨质疏松症的患病率高于非西班牙裔白人，尤其是在女性中。
鉴于少数族裔在获得医疗保健方面面临的挑战以及骨折发病率，需要进一步研究以了解较年轻的纳瓦霍族人较低的骨矿物质密度是否预示着未来骨折的风险，以及相对于骨矿物质密度的骨折风险。
