目的：评价一项心血管疾病（CVD）生活方式干预试验中低社会支持（SS）与饮食依从性之间的关系。设计：前瞻性子研究。背景和参与者：随机对照试验中住院心脏病患者的血亲/同居者（n = 458； 66%为女性，35%为非白人，平均年龄50岁）。主要结局指标：使用MEDFICTS（肉类、鸡蛋、乳制品、油炸食品、烘焙食品中的脂肪、方便食品、餐桌上添加的脂肪和零食）工具不遵守饮食；促进冠心病患者康复的社会支持量表的SS应用分析：逻辑回归模型调整混杂因素。结果：1年内不遵守饮食建议的显著预测因子（P < 0.05）包括低SS、体重指数和腰围增加、体力活动减少、抑郁、行动前阶段变化、对照组分配和男性。基线时SS低2.7的患者与SS高的患者相比，1年后不坚持饮食的几率更大（95%置信区间= 1.1 - 6.4）；没有小组间的互动。结论和意义：基线时的低SS与1年后不坚持饮食独立相关，表明低SS的家庭成员可能由于饮食依从性差而增加心血管疾病的风险。
Objective: Evaluate the relationship between low social support (SS) and adherence to diet in a cardiovascular disease (CVD) lifestyle intervention trial.Design: Prospective substudy.Setting and Participants: Blood relatives/cohabitants of hospitalized cardiac patients in a randomized controlled trial (n = 458; 66% female, 35% nonwhite, mean age 50 years).Main Outcome Measures: Non-adherence to diet using MEDFICTS (Meats, Eggs, Dairy, Fried foods, fat In baked goods, Convenience foods, fats added at the Table, and Snacks) tool; SS using the Enhancing Recovery in Coronary Heart Disease Patients Social Support Instrument.Analysis: Logistic regression models adjusted for confounders.Results: Significant predictors (P < .05) of non-adherence to diet recommendations at 1 year included low SS, increased body mass index and waist size, lower physical activity, depression, pre-action stages of change, control group assignment, and being male. Those with low SS at baseline 2.7 greater odds of being non-adherent to diet at 1 year vs those with higher SS (95% confidence interval = 1.1 - 6.4); there was no interaction by group assignment.Conclusion and Implications: Low SS at baseline was independently associated with non-adherence to diet at I year, suggesting that Family members with low SS may be at heightened CVD risk as a result of poor dietary adherence.
