Abstract
Midwifery is a high-stressed job, and midwiferies are prone to many stresses threatening their health over long working hours; further, it also influences their ability and the quality of patient care. Midwifery is characterized with sleep disorder influenced by stress and working shifts. This research is conducted to study the effect of Ginkgo biloba on midwiferies sleep quality in hospitals. In this random controlled clinical trial, thirty midwiferies working in hospitals were assigned into two groups of receiving treatment and placebo. The participants suffering from sleep disorder received the packs containing G. biloba and/or placebo and a pill every 12 h was prescribed over 30 days. Demographic and Pittsburgh Sleep Quality Index questionnaire were distributed prior and after Ginkgo. Following a 1-week cleaning, Ginkgo group received placebo; while, the placebo received Ginkgo over 30 days. Pittsburgh Sleep Quality Index questionnaire was also completed at the beginning and end of this period. Data were collected and descriptive, and inferential statistics was analyzed by t-test, Anova test through SPSS-20. At significant level P = 0.457, it may be expressed that there is no significant difference seen in the total sleep quality following treatment in experimental and control group. Research results demonstrate that Ginkgo has no effect on sleep quality of working midwiferies. Therefore, it is necessary to conduct longer studies with larger sample volumes.
