Excess added sugar intake contributes to tooth decay risk in Alaska Native communities. The goal of this exploratory study was to determine if there is seasonal variation in total added sugar intake or in the leading sources of added sugars in a Yup'ik population. Data were collected in spring and winter from 2008-2010 using self-reported intake data measured by 24-hour recall and by hair biomarker (carbon and nitrogen stable isotope). Seventy Yup'ik participants ages 14-70 years were recruited from two communities and data were collected twice from a subset of 38 participants. Self-reported added sugar intake (g/day), biomarker-predicted added sugar intake (g/day), and leading sources of added sugar were calculated. Seasonal variation was evaluated using a paired sample t-test. Total added sugar intake was 93.6 g/day and did not significantly differ by season. Sodas and other sugar-sweetened beverages (e.g. Tang, Kool-Aid) were the leading sources and added sugar from these sources did not significantly differ by season (p=.54 and p=.89, respectively). No seasonal variation in added sugar intake was detected by either self-report or biomarker. Dietary interventions that reduce intake of added sugars have the potential to reduce tooth decay in Yup'ik communities.
过量的添加糖摄入会增加阿拉斯加原住民社区的龋齿风险。本探索性研究的目的是确定Yup'ik 人群的总添加糖摄入量或添加糖的主要来源是否存在季节性变化。2008-2010 年期间，通过 24 小时回忆和头发生物标志物（碳和氮稳定同位素）测量的自我报告摄入量数据，在春季和冬季收集数据。从两个社区招募了 70 名年龄在 14-70 岁的Yup'ik 参与者，并从 38 名参与者的亚组中两次收集数据。计算了自我报告的添加糖摄入量（g/天）、生物标志物预测的添加糖摄入量（g/天）和添加糖的主要来源。使用配对样本 t 检验评估季节性变化。总添加糖摄入量为 93.6g/天，季节间无显著差异。苏打水和其他含糖饮料（如 Tang、Kool-Aid）是主要来源，这些来源的添加糖摄入量在季节间无显著差异（分别为 p=.54 和 p=.89）。无论是通过自我报告还是生物标志物，都没有检测到添加糖摄入量的季节性变化。减少添加糖摄入量的饮食干预有可能减少 Yup'ik 社区的龋齿。
