Abstract

Background: Limited studies have examined the contribution of lifestyle behaviors to dietary quality among individuals with and without type 2 diabetes. Objective: To examine the relationship between selected lifestyle behaviors independently, and in combination with other lifestyle behaviors, and dietary quality by diabetes status. Methods: This study used a representative sample of U.S. adults 20+ years of age (n = 4097) using NHANES 20072010. Six individual lifestyle behaviors were selected as main exposure variables: Self-reported alcohol consumption, sleep adequacy, on a special diet, supplement intake, smoking status, and physical activity. Total HEI-2010 and the AHEI-2010 were used as measures of dietary quality and were calculated using data from the first 24-hour dietary recall. Multivariable Linear Regression was used to examine relationships among lifestyle behaviors independently, and in combination with total HEI-2010 and AHEI-2010 scores, after adjusting for demographic and health characteristics. Results: Selected lifestyle behaviors independently, and in combination, were significantly associated with total HEI2010 and AHEI-2010 scores by diabetes status (p < 0.05). Diabetics were more likely to report being on a special diet, taking dietary supplements, and not drinking alcohol but were less likely to report getting adequate sleep and meeting physical activity guidelines. Results indicate that being on a special diet and taking dietary supplements had the highest coefficient in relation to dietary quality for diabetics [total HEI-2010 score: β = 5.08, p = 0.0011 for on a special diet, total AHEI-2010 score: β = 3.89, p = 0.0019 for supplement intake]. However, the coefficients of the combined Lifestyle Behaviors score in relation to dietary quality were fairly similar for diabetics and prediabetics (p < 0.001). Conclusion: Diabetics did better on several of the lifestyle indicators and had higher HEI-2010 and AHEI-2010 scores, suggesting that diabetic education and nutrition counseling may have influence on their behavior.
美国成年人糖尿病状况与饮食质量的生活方式行为
背景:有限的研究调查了患有和不患有2型糖尿病的个体的生活方式行为对饮食质量的贡献。目的:通过糖尿病状况,研究独立选择的生活方式行为以及与其他生活方式行为的结合与饮食质量之间的关系。方法:本研究使用NHANES 20072010对20岁以上的美国成年人(n=4097)进行代表性抽样。选择六种个人生活方式行为作为主要暴露变量:自我报告的饮酒量、睡眠充足率、特殊饮食、补充剂摄入、吸烟状态和体育活动。总HEI-2010和AHEI-2010被用作膳食质量的衡量标准,并使用第一次24小时膳食召回的数据进行计算。在对人口统计学和健康特征进行调整后,使用多变量线性回归独立检查生活方式行为之间的关系,并结合HEI-2010和AHEI-2010总分。结果:选择的生活方式行为独立或组合与糖尿病状态下的HEI2010和AHEI-2010总分显著相关(p<0.05)。糖尿病患者更有可能报告有特殊饮食、服用膳食补充剂和不饮酒,但不太可能报告有充足的睡眠和符合体育活动指南。结果表明,特殊饮食和服用膳食补充剂与糖尿病患者的饮食质量相关系数最高[HEI-2010总分:β=5.08,特殊饮食p=0.0011,AHEI-2010总分:β=3.89,补充剂摄入量p=0.0019]。然而,糖尿病患者和糖尿病前期患者的生活方式行为综合评分与饮食质量的相关系数非常相似(p<0.001)。结论:糖尿病患者在一些生活方式指标上表现更好,HEI-2010和AHEI-2010评分更高,这表明糖尿病教育和营养咨询可能会对他们的行为产生影响。
