目的:短期和长期睡眠都与肾功能下降有关;然而,很少有研究研究睡眠之间的关系,水合状态,和普通的水摄入。这项研究旨在评估睡眠质量之间的关系,水合状态,和孕妇的白开水摄入量。
方法:采用横断面研究方法,收集了2019年5月至2021年2月在医院进行定期检查的380名孕妇的数据。
结果:每天的普通水摄入量有统计学上的显着差异(x2=14.118,p=0.001),PSQI评分(x2=77.708,p<0.001),睡眠持续时间(x2=67.569,p>0.001),主观睡眠质量(x2=67.441,p=0.001),入睡时间(x2=64.782,p<001),睡眠障碍(x2=70.853,p<0.001),不同水合状态组的日间功能障碍(x2=38.441,p<0.001)。序数logistic回归分析结果表明,普通水的摄取量≥1500mL/d(OR=0.40,95%CI=0.24~0.67),良好的主观睡眠质量(OR=0.15,95%CI=0.07~0.32),入睡时间短(OR=0.32,95%CI=0.14~0.70),睡眠8h(OR=0.06,95%CI=0.02~0.17),睡眠时间6~7h(OR=0.19,95%CI=0.07~0.54),无睡眠障碍(OR=0.31,95%CI=0.11~0.89),高睡眠效率(OR=0.46,95%CI=0.03〜0.79)是与最佳水合状态相关的因素。睡眠持续时间和白天功能障碍部分介导了普通水摄入对水合状态的影响。睡眠时长的中介效应为-0.036,占整体效应的14.006%。日间功能障碍的中介效应为-0.024,占总效应的9.459%。
结论:孕妇的水合状态可能受每日普通水摄入量和睡眠质量的影响。
OBJECTIVE: Both short and long sleep durations are associated with decreased kidney function; however, few studies have examined the relationship between sleep, hydration status, and plain water intake. This study aimed to assess the relationship between sleep quality, hydration status, and plain water intake in pregnant women.
METHODS: A cross-sectional study method was used to collect data from 380 pregnant women with regular examinations at the hospital between May 2019 and February 2021.
RESULTS: There were statistically significant differences in daily plain water intake (x2 = 14.118, p = 0.001), PSQI score (x2 = 77.708, p < 0.001), sleep duration (x2 = 67.569, p > 0.001), subjective sleep quality (x2 = 67.441, p = 0.001), time to fall asleep (x2 = 64.782, p < 001), sleep disorders (x2 = 70.853, p < 0.001), and daytime dysfunction (x2 = 38.441, p < 0.001) among different hydration status groups. Ordinal logistic regression results indicated that the intake of plain water ≥1500 mL/d (OR = 0.40, 95% CI = 0.24~0.67), good subjective sleep quality (OR = 0.15, 95% CI = 0.07~0.32), short time to fall asleep (OR = 0.32, 95% CI = 0.14~0.70), 8 h of sleep (OR = 0.06, 95% CI = 0.02~0.17), 6-7 h of sleep (OR = 0.19, 95% CI = 0.07~0.54), no sleep disturbance (OR = 0.31, 95% CI = 0.11~0.89), and high sleep efficiency (OR = 0.46, 95% CI = 0.03~0.79) were factors that were correlated with optimal hydration status. Sleep duration and daytime dysfunction partially mediated the effect of plain water intake on hydration status. The mediating effect of sleep duration was -0.036, accounting for 14.006% of the overall effect. The mediating effect of daytime dysfunction was -0.024, accounting for 9.459% of the overall effect.
CONCLUSIONS: The hydration status in pregnant women may be affected by daily plain water intake and sleep quality.
