The purpose of this cross-sectional study was to determine the differences in areal bone mineral density (aBMD) based on alcohol consumption behaviors, bone-loading history as assessed by a bone-specific physical activity questionnaire (BPAQ), and the body mass index (BMI). College-aged female students ( = 112) were recruited from the universities in Seoul and Gyeonggi province, South Korea. The aBMD of the lumbar spine and non-dominant side of the proximal femur (total hip, TH; femoral neck, FN; femoral trochanter, FT) were measured using dual energy X-ray absorptiometry (DXA). Alcohol consumption was determined by the frequency and amount of alcohol intake during the past 12 months using a self-reported questionnaire. The X-scan plus II was used to measure height (cm), body mass (kg), fat-free mass (FFM, kg), and % body fat. Drinking two or more times alcohol per week was associated with greater aBMD of the TH ( = 0.04-0.002) and FN ( = 0.043) compared to a lower frequency of alcohol consumption and 2-4 times per month, respectively. Based on the drinking amount per occasion, there were no significant group differences ( > 0.05) in aBMD at any of the sites. The highest group of total BPAQ had greater aBMD of the TH, FN, and FT versus the lowest ( = 0.023-0.009) and mid of total BPAQ groups ( = 0.004-0.009). Additionally, the highest group had greater aBMD of the lumbar spine compared to the mid group ( = 0.001). No significant group differences in aBMD at any of the sites were noted based on the BMI ( > 0.05). Young college-aged women with greater bone-loading physical activity showed greater aBMD at the TH, FN, FT, and lumbar spine, while a moderate alcohol intake was associated with greater aBMD of the TH and FN. These findings have clinical implications for young women who may not participate in high-impact physical activity and are binge drinkers.
本横断面研究旨在确定基于饮酒行为、骨特异性体力活动问卷 (BPAQ) 评估的骨负荷史和体重指数 (BMI) 的骨密度 (aBMD) 差异。从韩国首尔和京畿道的大学招募了 112 名年轻的女大学生。使用双能 X 射线吸收法 (DXA) 测量腰椎和非优势侧股骨近端 (全髋，TH；股骨颈，FN；股骨转子间，FT) 的 aBMD。使用自我报告的问卷通过过去 12 个月的饮酒频率和饮酒量来确定饮酒情况。使用 X 扫描加 II 测量身高 (cm)、体重 (kg)、去脂体重 (FFM，kg) 和体脂百分比。与较低的饮酒频率（每周饮酒 1-2 次）相比，每周饮酒 2 次或以上与 TH（=0.04-0.002）和 FN（=0.043）的 aBMD 更高，而每月饮酒 2-4 次。基于每次饮酒量，任何部位的 aBMD 在各组之间均无显著差异（>0.05）。总 BPAQ 的最高组与最低和中间组相比，TH、FN 和 FT 的 aBMD 更高（=0.023-0.009）。此外，最高组的腰椎 aBMD 高于中间组（=0.001）。任何部位的 aBMD 在各组之间均无显著差异（>0.05）。具有较大骨负荷体力活动的年轻女大学生 TH、FN、FT 和腰椎的 aBMD 更高，而适度饮酒与 TH 和 FN 的 aBMD 更高相关。这些发现对可能不参加高强度体力活动和 binge 饮酒的年轻女性具有临床意义。
