Regular nutrition label use may have important long-term health implications. To our knowledge, the role of nutrition label use in protecting against the development of chronic diseases was unexplored prospectively before this study. We tested the association between nutrition label use and risk of a future diabetes diagnosis in a multiethnic US cohort. Data from the ongoing National Longitudinal Survey of Youth-1979 (NLSY79) were analyzed. From 2002 (baseline) to 5 follow-up time points (2004-2012), 7150 diabetes-free, multiethnic young adults were prospectively followed for a diagnosis of incident diabetes. Nutrition label use, diabetes diagnosis, time to diabetes diagnosis, and all covariates were self-reported. Between January 2002 and September 2013, 430 participants (6.0%) were diagnosed with diabetes. A weighted, multivariable, extended Cox regression was conducted, which suggested that in nutrition label users, the HR of diabetes diagnosis risk decreased significantly with time (-nutrition label use × time interaction < 0.05) compared with risk in nutrition label nonusers. There is an association between nutrition label use and diabetes risk in the longer term. However, additional longitudinal research with a robust dietary intake assessment is needed to test this hypothesis.
经常使用营养标签可能对长期健康具有重要意义。据我们所知，在本研究之前，营养标签使用在预防慢性病发展方面的作用尚未得到前瞻性研究。我们在美国一个多民族队列中测试了营养标签使用与未来糖尿病诊断风险之间的关联。对正在进行的1979年全国青年纵向调查（NLSY79）的数据进行了分析。从2002年（基线）到5个随访时间点（2004 - 2012年），对7150名无糖尿病的多民族年轻成年人进行了前瞻性随访以诊断新发糖尿病。营养标签使用情况、糖尿病诊断、糖尿病诊断时间以及所有协变量均为自我报告。在2002年1月至2013年9月期间，430名参与者（6.0%）被诊断患有糖尿病。进行了加权多变量扩展Cox回归分析，结果表明与不使用营养标签者相比，使用营养标签者糖尿病诊断风险的风险比随时间显著降低（营养标签使用情况×时间交互作用<0.05）。从长期来看，营养标签使用与糖尿病风险之间存在关联。然而，需要进行更多具有可靠饮食摄入量评估的纵向研究来验证这一假设。
