Purpose The purpose of this study was to examine the relationship between sleep duration and glycemic control in adult Hispanic patients with uncontrolled type 2 diabetes. Methods This cross-sectional study used baseline data from 317 Hispanic adults with uncontrolled type 2 diabetes who participated in a randomized controlled trial testing a peer support intervention to improve diabetes control. To be eligible, participants had to be 18 years or older and have A1C >7% in the 3 months prior to randomization. Glycemic control was assessed by A1C ascertained through medical chart review; higher A1C levels reflected poorer glycemic control. Sleep duration (hours/night), diabetes control behaviors, and demographics were obtained by interviewer-administered questionnaire. We used multivariable generalized linear models to estimate the association between sleep duration and glycemic control. Results Forty-three percent of participants reported sleeping fewer than 7 hours per night. Sleep duration (hours/night) was inversely associated with A1C levels; however, the relationship was no longer statistically significant after adjusting for insulin status. Conclusions Sleep duration was not significantly associated with glycemic control in this sample of Hispanic adults with uncontrolled type 2 diabetes when adjusting for insulin. Future research should continue to explore this relationship among Hispanic adults with diabetes using an objective measure of sleep duration and a larger sample of Hispanic adults with both controlled and uncontrolled type 2 diabetes to determine if these results hold true.
目的 本研究旨在探讨睡眠时长与血糖控制在未经控制的 2 型糖尿病西班牙裔成年患者中的关系。
方法 本横断面研究使用了参加一项测试同伴支持干预以改善糖尿病控制的随机对照试验的 317 名未经控制的 2 型糖尿病西班牙裔成年人的基线数据。符合条件的参与者必须年满 18 岁，且在随机分组前 3 个月的 A1C ＞7%。通过病历回顾确定糖化血红蛋白（A1C）来评估血糖控制情况；A1C 水平越高，表明血糖控制越差。通过访谈者管理的问卷获得睡眠时长（小时/夜）、糖尿病控制行为和人口统计学数据。我们使用多变量广义线性模型来估计睡眠时长与血糖控制之间的关联。
结果 43%的参与者报告每晚睡眠时间少于 7 小时。睡眠时长（小时/夜）与 A1C 水平呈负相关；然而，在调整胰岛素状态后，这种关系不再具有统计学意义。
结论 在调整胰岛素后，本研究中未经控制的 2 型糖尿病西班牙裔成年人中，睡眠时长与血糖控制之间无显著关联。未来的研究应继续使用睡眠时长的客观测量方法和更大的控制和未经控制的 2 型糖尿病西班牙裔成年人样本来探索该关系，以确定这些结果是否成立。
