The association between the dietary approach to stop hypertension (DASH) and sleep status is well-documented. Nevertheless, a consistent relationship with employees population has yet to be known. Thus, we aimed to investigate the relationship between the DASH diet and sleep quantity/quality among Iranian employees of both genders.
We enrolled 337 persons whose Sleep status was assessed through the Pittsburgh Sleep Quality Index. A validated Food Frequency Questionnaire was used to measure the DASH diet score. Analysis of variance and covariance, chi-square, and multinomial logistic regression tests were used as appropriate.
Our findings demonstrated that, even after adjusting for multiple potential confounders the odds of poor sleep quality were not significantly related to the higher DASH diet adherence (OR = 0.69, 95% CI: 0.38-1.27). However, participants in the highest tertiles of DASH had lower chances of experiencing short sleep duration compared to those in the lowest one (OR = 0.53; 95% CI: 0.30-0.96).
The present study indicated that Iranian employees with a higher adherence to the DASH diet had considerably lower odds of having short sleep; however DASH adherence has no significant effect on sleep quality. More prospective and controlled investigations are required to confirm these findings.
采用终止高血压膳食疗法（DASH）与睡眠状况之间的关联已有充分记录。然而，其与员工群体之间的稳定关系尚不清楚。因此，我们旨在调查伊朗男女员工中DASH饮食与睡眠数量/质量之间的关系。
我们招募了337名通过匹兹堡睡眠质量指数评估睡眠状况的人员。使用经过验证的食物频率问卷来测量DASH饮食得分。根据情况使用方差分析、协方差分析、卡方检验和多项逻辑回归检验。
我们的研究结果表明，即使在对多个潜在混杂因素进行调整后，睡眠质量差的几率与较高的DASH饮食依从性也没有显著关联（比值比[OR]=0.69，95%置信区间[CI]：0.38-1.27）。然而，与处于最低三分位数的参与者相比，处于DASH最高三分位数的参与者经历短睡眠时间的几率较低（OR=0.53；95%CI：0.30-0.96）。
本研究表明，伊朗员工中对DASH饮食依从性较高者出现短睡眠的几率显著较低；然而，DASH依从性对睡眠质量没有显著影响。需要更多前瞻性和对照研究来证实这些发现。
