研究饮食模式往往比单独的营养素或食物更能提供信息。我们发现，谨慎的饮食模式（富含蔬菜和鱼类）与老年男性髋部骨密度减少有关。谨慎的饮食模式可能是减少骨质流失的潜在生活方式策略。本研究旨在通过因子分析确定老年男性队列的基线饮食模式，并评估饮食模式是否与全髋关节和股骨颈骨密度随时间变化（%ΔBMD）相关。参与者（n = 4379，平均年龄72.9±5.5岁）来自男性骨质疏松性骨折（MrOS）前瞻性队列研究，在基线（2000年3月- 2002年4月）收集饮食数据，在基线和第二次访问（2005年3月- 2006年5月）测量骨密度。通过简短的街区食物频率问卷（FFQ）评估膳食摄入量；因子分析用于推导饮食模式。采用双能x线骨密度仪（DXA）测定骨密度；%ΔBMD从基线到第2次访问计算。我们使用广义线性回归来估计饮食模式评分四分位数中%ΔBMD的最小二乘（LS）平均值，并对潜在的混杂因素进行了调整。得出了两种主要的饮食模式：谨慎型（大量食用蔬菜、沙拉和非炸鱼）和西式（大量食用汉堡、薯条、加工肉类、奶酪和糖果/甜点）。坚持谨慎模式与总髋关节%ΔBMD之间存在负相关（在调整年龄和临床位置后p趋势= 0.028；在进一步调整吸烟、钙补充剂使用、糖尿病、高血压和总能量摄入后p趋势= 0.033）。饮食模式和%ΔBMD之间没有其他一致的联系。更坚持谨慎的饮食模式可能会减轻老年男性髋部骨密度损失（%ΔBMD）。
Studying dietary patterns is often more informative than individual nutrients or foods. We found that a Prudent dietary pattern (rich in vegetables and fish) was associated with reduced loss of total hip BMD in older men. A Prudent dietary pattern may be a potential lifestyle strategy for minimizing bone loss. This study aimed to identify baseline dietary patterns using factor analysis in a cohort of older men and to evaluate whether the dietary patterns were associated with bone mineral density change (%ΔBMD) at the total hip and femoral neck over time. Participants (n = 4379; mean age 72.9 ±5.5 years) were from the Osteoporotic Fractures in Men (MrOS) prospective cohort study and had dietary data collected at baseline (March 2000-April 2002) and BMD measured at baseline and Visit 2 (March 2005-May 2006). Dietary intake was assessed with a brief Block food frequency questionnaire (FFQ); factor analysis was used to derive dietary patterns. BMD was measured by dual-energy x-ray absorptiometry (DXA); %ΔBMD was calculated from baseline to Visit 2. We used generalized linear regression to estimate least square (LS) means of %ΔBMD in quartiles of the dietary pattern scores adjusted for potential confounding factors. Two major dietary patterns were derived: Prudent (abundant in vegetables, salad, and non-fried fish) and Western (rich in hamburger, fries, processed meats, cheese, and sweets/desserts). There was an inverse association between adherence to the Prudent pattern and total hip %ΔBMD (p-trend = 0.028 after adjusting for age and clinical site; p-trend = 0.033 after further adjustment for smoking, calcium supplement use, diabetes, hypertension, and total energy intake). No other consistent associations between dietary patterns and %ΔBMD were observed. Greater adherence to a Prudent dietary pattern may attenuate total hip BMD loss (%ΔBMD) in older men.
