Previous studies indicated that excessive screen time was associated with hypertension in children and adolescents. In our hospital, pregnant women tended to spend a lot of time on electronic devices like smartphones. We aimed to explore the relationship between the screen time and hypertensive disorders of pregnancy (HDP).
A case-control study was conducted from November 2019 to May 2020. A total of 160 women with HDP and 197 healthy controls who gave birth to children in the same hospital were recruited and information was recorded by questionnaires. Multivariate analysis was conducted to assess the effect of screen time on HDP.
The results showed that, exposure to electronic screen before nocturnal sleep in cases was significantly longer than that in controls (P = 0.011, odds ratio = 1.50). Smartphones (and/or tablet computers) used only for entertainment also significantly increased the susceptibility to HDP (P < 0.001, odds ratio = 2.84). Other related factors were following: work experience during pregnancy (P = 0.034, odds ratio = 0.53), history of diabetes mellitus (P = 0.013, odds ratio = 2.55), history of family hypertension (P < 0.001, odds ratio = 3.81), body mass index of pre-pregnancy (>25 kg/m ) (P < 0.001, odds ratio = 6.16).
In conclusion, long exposure to electronic screen before nocturnal sleep and the smartphones usage for only entertainment may be associated with the susceptibility to HDP.
既往研究表明，儿童和青少年屏幕使用时间过长与高血压有关。在我院，孕妇往往在智能手机等电子设备上花费大量时间。我们旨在探讨屏幕使用时间与妊娠期高血压疾病（HDP）之间的关系。
2019年11月至2020年5月进行了一项病例对照研究。共招募了160例患有HDP的女性和197例在同一家医院分娩的健康对照者，并通过问卷调查记录信息。进行多变量分析以评估屏幕使用时间对HDP的影响。
结果显示，病例组夜间睡眠前接触电子屏幕的时间明显长于对照组（P = 0.011，比值比 = 1.50）。仅用于娱乐的智能手机（和/或平板电脑）也显著增加了患HDP的易感性（P < 0.001，比值比 = 2.84）。其他相关因素如下：孕期工作经历（P = 0.034，比值比 = 0.53）、糖尿病史（P = 0.013，比值比 = 2.55）、家族高血压史（P < 0.001，比值比 = 3.81）、孕前体重指数（>25 kg/m²）（P < 0.001，比值比 = 6.16）。
总之，夜间睡眠前长时间接触电子屏幕以及仅将智能手机用于娱乐可能与患HDP的易感性有关。
