Study on effect of mindfulness intervention on sleep quality and pre-bedtime mobile phone dependence in young patients with acute myocardial infarction
Objective To explore the effect of mindfulness intervention on sleep quality and pre-bedtime mobile phone dependence in young patients with acute myocardial infarction.Methods A total of 66 young patients with acute myocardial infarction were selected by convenience sampling method.They were evaluated by semi-structured interview,Pittsburgh Sleep Quality Index(PSQI),Mobile Phone Addiction Index(MPAI)and Self-rating Anxiety Scale(SAS),and also intervened by mindfulness therapy.The clinical data were analyzed,and sleep quality,mobile phone dependence and anxiety were compared before and after the intervention.Results Among the 66 young patients with acute myocardial infarction,staff and other independent occupations accounted for 81.8%(54/66),body mass index(BMI)overweight(25-30 kg/m2)and obesity(>30 kg/m2)accounted for 71.2%(47/66),they used mobile phones too long at bedtime,fell asleep late,and had high probability of using mobile phones the first time after waking up in mid-night and getting up.Before intervention,the duration of mobile phone use at bedtime,the total score of MAPI,PSQI and SAS were(5.08±2.52)h,(71.59±1.98)points,(11.03±3.95)points and(49.08±8.44)points;at 4 weeks of intervention,they were(4.21±1.73)h,(62.64±4.10)points,(9.58±3.37)points and(45.29±8.62)points;at 8 weeks of intervention,they were(3.97±1.60)h,(57.06±4.43)points,(8.80±2.88)points and(42.24±5.64)points.There were significant differences in the duration of mobile phone use at bedtime,total MAPI score,total PSQI score,and total SAS score in young patients with acute myocardial infarction before intervention and at 4 and 8 weeks of intervention(P<0.05).At 4 and 8 weeks of intervention,the duration of mobile phone use at bedtime was shorter than that before intervention,and the total MAPI score,total PSQI score,and total SAS score were lower than those before intervention in young patients with acute myocardial infarction(P<0.05).At 8 weeks of intervention,the total MAPI score and total SAS score of young patients with acute myocardial infarction were lower than those at 4 weeks of intervention(P<0.05).At 4 and 8 weeks of intervention,the duration of mobile phone use at bedtime of young patients with acute myocardial infarction were gradually earlier than before intervention.Conclusion Mindfulness intervention can reduce the duration of pre-bedtime mobile phone use,and improve the sleep quality,mobile phone dependence and anxiety of young patients with acute myocardial infarction.
