很少有研究描述健康的非洲年轻妇女的骨密度(BMD)。在我们对496名年龄25岁的乌干达妇女的研究中，我们发现妇女的健康骨密度平均低于标准参考范围。可用于骨密度测量的参考范围需要更高的精确度。目的描述撒哈拉以南非洲健康年轻女性的骨密度(BMD)、营养物质摄入量和身体成分的数据有限。使用一组年轻、健康的乌干达妇女的基线数据，我们总结了骨健康和骨量减少的相关危险因素。方法使用16-25岁乌干达妇女的基线数据，她们参加了一项正在进行的骨健康队列研究，同时使用注射避孕药和口服HIV暴露前预防措施，我们描述了骨密度、营养摄入量、体力活动和身体成分的分布。结果在496名健康的乌干达妇女中，平均年龄为20岁(四分位数范围[IQR]19-21)，平均脂肪/瘦质量比为0.55(IQR 0.46-0.64)，腰椎和总髋部BMD中位数分别为0.9g/cm2(IQR 0.9-1.0)。对于腰椎，Z分数分布总体上低于参考人群，分别有9.3%和36.3%的女性Z分数标准差低于参考范围。就全髋关节而言，Z评分与参考人群相似，分别有1.0%和12.3%的女性Z评分标准差低于参考范围。在注册前一周，41.1%的女性摄入了7份钙，56.5%的女性摄入了7份维生素D，98.6%的女性报告了≥2.5小时的体力活动。体脂越多，下腰椎BMD的发生率越高(P<；0.01，脂肪：瘦质量比、全身脂肪百分比、腰围和BMI)。结论乌干达年轻女性的骨密度健康水平低于参考范围人群。
Few studies have characterized bone mineral density (BMD) among health young African women. In our study of 496 Ugandan women age ≤25 years, we found that women had healthy BMD that were lower on average than the standard reference ranges. Reference ranges available for BMD measurements need greater precision.PurposeData describing bone mineral density (BMD), nutrient intake, and body composition among healthy, young women in sub-Saharan Africa are limited. Using baseline data from a cohort of young, healthy Ugandan women, we summarize bone health and associated risk factors for reduced bone mass.MethodsUsing baseline data from Ugandan women ages 16–25 years who enrolled in an ongoing cohort study of bone health with concurrent use of injectable contraception and oral HIV pre-exposure prophylaxis, we describe the distribution of BMD, nutrient intake, physical activity, and body composition. The association of low BMD (1 or more standard deviations below the age, sex, and race-matched reference range from the USA) and calcium intake, vitamin D intake, physical activity, and body composition was estimated using multivariable logistic regression.ResultsIn 496 healthy, Ugandan women with median age of 20 years (interquartile range [IQR] 19–21) and median fat:lean mass ratio of 0.55 (IQR 0.46–0.64), median lumbar spine and total hip BMD was 0.9g/cm2(IQR 0.9–1.0) each. For lumbar spine,Z-score distributions were lower overall than the reference population and 9.3% and 36.3% of women hadZ-score >2 and >1 standard deviations below the reference range, respectively. For total hip,Z-scores were similar to the reference population and 1.0% and 12.3% of women hadZ-score >2 and >1 standard deviations below the reference range, respectively. In the week prior to enrollment, 41.1% of women consumed >7 servings of calcium, 56.5% had >7 servings of vitamin D, and 98.6% reported ≥2.5 h of physical activity. Having greater body fat was associated with greater frequency of low lumbar spine BMD (p<0.01 for fat:lean mass ratio, total body fat percentage, waist circumference, and BMI).ConclusionYoung Ugandan women exhibited healthy levels of BMD that were lower than the reference range population.
