背景资料：健康的饮食模式和体重增加之间的负相关性已经在白色人群中显示出来，但在少数几项针对非裔美国人的研究中并不明显，非裔美国人是肥胖的高危人群。这项研究包括41,351名年龄在21 - 54岁之间的妇女，她们于1995年参加了黑人妇女健康研究。参与者通过邮寄问卷每两年报告一次1995年和2001年的饮食摄入量和当前体重。通过因子分析，确定了两种主要的饮食模式：“蔬菜/水果”模式和“肉类/油炸食品”模式。采用多变量混合线性回归模型，根据每种饮食模式估计14年随访的平均体重增加。结果：在1995年和2001年保持相似饮食模式的妇女中，蔬菜/水果模式与14年以上体重增加显著减少相关（最高和最低五分位数分别为10.88和11.94公斤;趋势P = 0.003），而肉类/油炸食品模式与体重增加显著相关（最高和最低五分位数分别为12.02和10.15千克;趋势P <0.001）。这些关联在年龄较大的女性中更为强烈
Background: An inverse association between healthy dietary patterns and weight gain that has been shown in white populations is not evident in the few studies in African Americans, a population at high risk of obesity.Objective: We prospectively assessed dietary patterns in relation to weight gain in African American women.Design: The study included 41,351 women aged 21-54 y at enrollment in 1995 in the Black Women's Health Study. Participants reported dietary intake in 1995 and 2001 and current weight every 2 y through mailed questionnaires. By using factor analysis, 2 major dietary patterns were identified: a "vegetables/fruit" pattern and a "meat/fried foods" pattern. Multivariable mixed linear regression models were used to estimate mean weight gain in 14 y of follow-up according to each dietary pattern.Results: Among women who maintained similar dietary patterns in 1995 and 2001, the vegetables/fruit pattern was associated with significantly less weight gain over 14 y (10.88 and 11.94 kg in the highest and lowest quintiles, respectively; P for trend = 0.003), whereas the meat/fried foods pattern was associated with significantly greater weight gain (12.02 and 10.15 kg in the highest and lowest quintiles, respectively; P for trend < 0.001). The associations were stronger among women aged
