A diet high in fruits and vegetables (F&Vs) is associated with decreased risk for cardiovascular disease, diabetes, and cancer. This study investigated the relationship between sociodemographic, health, and psychosocial factors and F&V consumption among overweight and obese U.S. veterans. Participants were recruited from two Veterans Affairs medical center sites in 2005. Two hundred eighty-nine participants completed a self-administered survey. Bivariate and multivariate linear regression models were built to examine the association between sociodemographic, health, and psychosocial variables and F&V consumption. Older age (B = 0.01; p < 0.001) and being Black (B = -0.18; p < 0.05) were related to increased F&V consumption. Reported tobacco use was inversely associated with F&V consumption (B = -0.30; p < 0.01). Greater self-efficacy (B = 0.07; p < 0.05), fewer perceived barriers (B = -0.14; p < 0.01), and correct knowledge of recommended daily F&V intake (B = 0.12; p <0.05) were related to eating more F&Vs. U.S. veterans disproportionately experience overweight and obese conditions. Age, race, tobacco use, and psychosocial factors should be considered carefully when developing dietary interventionsamong overweight ana obese U.S. veterans.
富含水果和蔬菜的饮食与心血管疾病、糖尿病和癌症风险降低相关。本研究调查了美国超重和肥胖退伍军人的社会人口统计学、健康和心理社会因素与水果和蔬菜摄入量之间的关系。2005年从两个退伍军人事务医疗中心招募了参与者。289名参与者完成了一份自我管理的调查问卷。构建了双变量和多变量线性回归模型,以检验社会人口统计学、健康和心理社会变量与水果和蔬菜摄入量之间的关联。年龄较大(B = 0.01;p < 0.001)和黑人身份(B = -0.18;p < 0.05)与水果和蔬菜摄入量增加有关。报告的吸烟情况与水果和蔬菜摄入量呈负相关(B = -0.30;p < 0.01)。自我效能感较高(B = 0.07;p < 0.05)、感知到的障碍较少(B = -0.14;p < 0.01)以及对每日推荐的水果和蔬菜摄入量有正确认识(B = 0.12;p < 0.05)与摄入更多水果和蔬菜有关。美国退伍军人中超重和肥胖的情况尤为普遍。在为超重和肥胖的美国退伍军人制定饮食干预措施时,应仔细考虑年龄、种族、吸烟情况和心理社会因素。
