Outline
To explore the association between nighttime social media use, sleep duration, and executive function decline in pregnant women, as well as the isotemporal substitution effect.
Pregnant women attending the obstetric outpatient department of Qilu Hospital in Jinan, Shandong Province were recruited using the convenience sampling method for a questionnaire survey. Single-factor, partition and isotemporal substitution models were used to analyze the relationship between nighttime social media use, sleep duration, and executive function decline in pregnant women.
A total of 628 pregnant women were included in the study. After adjusting for confounding factors, both the single model and the partition model indicated that nighttime social media use duration was significantly positively correlated with scores in total executive function decline (β=0.980; β=0.965), memory (β=0.595; β=0.585), and inhibitory control dimension (β=0.385; β=0.379) (all P<0.01). In contrast, sleep duration was significantly negatively correlated with scores in total executive function decline (β=-0.414; β=-0.402), memory (β=-0.255; β=-0.248), and inhibitory control dimension (β=-0.159; β=-0.154) (all P<0.05). The isotemporal substitution model showed that increasing sleep by 30 minutes to replace an equivalent amount of nighttime social media use was associated with a decrease in the total score of executive function decline among pregnant women (β=-2.047, P<0.001). The improvement in the memory dimension (β=-1.261, P<0.001) was greater than that in the inhibitory control dimension (β=-0.786, P<0.001).
Replacing 30 minutes of nighttime social media use with sleep is associated with reduced executive function decline in pregnant women. It is recommended that sleep management and digital behavior adjustment be incorporated into clinical interventions and health education to promote cognitive health in pregnant women and improve maternal and neonatal outcomes.
