We aimed to find the relationship between sleep duration and impaired fasting glucose according to working type in non-regular workers using the 2016 and 2017 Korean National Health And Nutrition Examination (KNHANE, 7th revision).
In the 1st and 2nd year (2016, 2017) of the 7th KNHANE, 16,277 people participated. Minors were excluded because this study was intended for individuals aged 19 years and older. As this study was based on wage workers, unemployment, self-employed workers, employers, unpaid family workers, and those who have insufficient answers such as unknown or no response were excluded. Regular workers were excluded because this study was intended for non-regular workers. Finally, a total of 2,168 people were included in the survey, except those who had been diagnosed with diabetes, had a fasting blood glucose level of 126 mg/dL or higher, or taking hypoglycemic agents or receiving insulin injections. To find the relationship between sleep duration and impaired fasting glucose according to work type in non-regular workers, multiple logistic regression analysis was performed by adjusting the general and occupational characteristics after stratification according to work type. All statistical analyses were performed using the SPSS software (version 26.0; SPSS Inc., Chicago, IL, USA).
In the case of insufficient sleep duration in irregular female workers, the odds ratio (OR) of impaired fasting glucose was statistically insignificant, but in the case of insufficient sleep duration in irregular male workers who have shift work, the odds ratio (OR) of impaired fasting glucose was significantly higher than that of sufficient sleep duration (Model 1, OR: 3.05, 95% confidence interval [CI]: 1.18-7.90; Model 2, OR: 2.81, 95% CI: 1.08-7.29).
Our findings demonstrate that insufficient sleep duration was associated with an increase in fasting blood glucose levels in non-regular male workers working shifts. This means that non-regular workers are in desperate need for adequate sleep and health care. We hope that our study will help improve the health of non-regular workers and more systematic and prospective follow-up studies will be conducted to further improve the health of non-regular workers.
我们旨在利用2016年和2017年韩国国家健康与营养检查（KNHANE，第7版），找出非正规工人中睡眠时长与空腹血糖受损之间按工作类型划分的关系。
在第7次KNHANE的第1年和第2年（2016年、2017年），有16277人参与。由于本研究针对19岁及以上的个体，因此排除了未成年人。由于本研究基于受薪工人，所以排除了失业者、个体经营者、雇主、无薪家庭工人以及那些回答不充分（如未知或无回应）的人。由于本研究针对非正规工人，所以排除了正规工人。最后，除了那些已被诊断患有糖尿病、空腹血糖水平在126mg/dL或更高、正在服用降糖药或接受胰岛素注射的人之外，共有2168人被纳入调查。为了找出非正规工人中按工作类型划分的睡眠时长与空腹血糖受损之间的关系，在根据工作类型分层后，通过调整一般和职业特征进行了多元逻辑回归分析。所有统计分析均使用SPSS软件（版本26.0；SPSS公司，美国伊利诺伊州芝加哥）进行。
在非正规女性工人睡眠时长不足的情况下，空腹血糖受损的优势比（OR）在统计学上不显著，但在从事轮班工作的非正规男性工人睡眠时长不足的情况下，空腹血糖受损的优势比（OR）显著高于睡眠充足时长的情况（模型1，OR：3.05，95%置信区间[CI]：1.18 - 7.90；模型2，OR：2.81，95%CI：1.08 - 7.29）。
我们的研究结果表明，从事轮班工作的非正规男性工人睡眠时长不足与空腹血糖水平升高有关。这意味着非正规工人迫切需要充足的睡眠和医疗保健。我们希望我们的研究将有助于改善非正规工人的健康状况，并且将进行更系统和前瞻性的随访研究，以进一步改善非正规工人的健康。
