目的：我们评估了纤维摄入量和水果/蔬菜消费量与体重增加的可能性在过去的5年在地中海population.Methods：我们进行了一个多用途的前瞻性队列（Seguimiento大学纳瓦拉研究）的参与者（5094名男性和6613名女性）的横断面分析。饮食测量使用半定量的食物频率问卷，以前在西班牙验证。我们根据能量调整的纤维摄入量的五分位数和水果/蔬菜摄入量的五分位数计算了前5年体重增加的比值比。我们还考虑了纤维摄入和水果/蔬菜消费的联合暴露。在纤维摄入量的五分之一至五分之一中，体重增加的多变量调整优势比为1.00男性为0.86、0.86、0.70和0.52（趋势P < 0.001），女性为1.00（参考）、0.99、1.08、1.05和0.72（趋势P = 0.005）。我们还观察到水果/蔬菜总摄入量与体重增加之间存在显著的负相关，但仅限于男性（调整后的比值比为0.78，0.89，0.70和0.54，五分位数2至5，趋势P < 0.001）。在过去5年中，水果/蔬菜摄入量与体重增加之间的负相关在总纤维摄入量高的人群中更为明显，而总纤维的益处在水果和蔬菜摄入量高的人群中更为明显。这项研究为纤维或水果/蔬菜摄入量与体重增加之间的负相关性提供了额外的支持，因此强调了用这些食物和富含纤维的产品代替某些膳食化合物的重要性，这可能有助于避免体重增加。(C)2006年爱思唯尔公司All rights reserved.
Objective: We assessed the association between fiber intake and fruit/vegetable consumption with the likelihood of weight gain in the previous 5 y in a Mediterranean population.Methods: We conducted a cross-sectional analysis of participants (5094 men and 6613 women) in a multipurpose prospective cohort (Seguimiento Universidad de Navarra Study). Diet was measured by using a semiquantitative food-frequency questionnaire that was previously validated in Spain. We calculated the odds ratios of weight gain in the previous 5 y according to quintiles of energy-adjusted fiber intake and quintiles of energy-adjusted of fruit/vegetable consumption. We also considered the joint exposure to fiber intake and fruit/vegetablc consumption.Results: Multivariate-adjusted odds ratios for weight gain across quintiles 1 to 5 of fiber intake were 1.00 (reference), 0.86, 0.86, 0.70, and 0.52 (P for trend < 0.001) among men and 1.00 (reference), 0.99, 1.08, 1.05, and 0.72 (P for trend = 0.005) among women. We also observed a significant inverse association between total fruit/vegetable consumption and weight gain, but only among men (adjusted odds ratios, 0.78, 0.89, 0.70, and 0.54 for quintiles 2 to 5, P for trend < 0.001). The inverse association between fruit/vegetable consumption and weight gain in the previous 5 y was more evident among those with a high intake of total fiber, and the benefit of total fiber was more evident among those with a high consumption of fruits and vegetables.Conclusions: This study provides additional support to the inverse association between fiber or fruit/vegetable consumption and weight gain, thus emphasizing the importance of replacing some dietary compounds by such foods and fiber-rich products, which may help to avoid weight gain.
