Objective: To explore the effect of sleep nursing intervention on infants' sleep status and gross motor development. Methods: Eighty-nine normal infants aged 8-9 months were randomly divided into two groups: experimental group (n=45) and control group (n=44). The control group received general family nursing intervention, while the experimental group received sleep nursing intervention.The whole intervention lasted for 56 consecutive natural days.Before and after the intervention, polysomnography (PSG) was used to monitor the electrophysiology during sleep, and Gesell development assessment scale was used to assess the gross motor development of the subjects. Results: There were no significant difference in sleep duration ((79.6±15.0)min, (78.3±20.4)min), REM sleep ((28.3±5.9)%, (28.2±9.0)%), NREM sleep((71.2±3.6)%, (72.6±5.1)%), deep sleep ((13.0±2.7)%, (13.6±3.7)%), sleep latency ((9.1±3.6)min, (8.7±2.9)min)and sleep efficiency ((78.6±1.9)%, (84.4±5.5)%)before and after the intervention in the control group (all P>0.05). The sleep duration ((82.7±13.4) min, (95.6±12.1) min), the proportion of deep sleep((10.4±4.7)%, (16.6±3.0)%), the proportion of NREM period((74.9±1.6)%, (76.9±1.0)%), the sleep efficiency((82.3±2.6)%, (89.4±3.7)%) in the experimental group were significantly different before and after the intervention(P<0.05). The differences value of the total sleep duration, NREM sleep proportion, deep sleep proportion and sleep efficiency before and after the intervention in the experimental group were significantly higher than those in the control group (P<0.05). The difference value of gross motor development between the two groups before and after intervention was statistically significant (test group (6.0±3.0), control group (2.0±1.5), t=4.687, P<0.05). Conclusion Sleep nursing intervention can improve the proportion of deep sleep in infants and improve the development level of gross exercise.The community health service can make sleep nursing intervention plan according to different families and infants' psychological development to optimize infants' deep sleep and promote the level of gross motor development.

The sleep duration ((82. 7±13. 4) min,(95. 6±12. 1) min),the proportion of deep sleep (( 10. 4 ± 4. 7)%, ( 16. 6 ± 3. 0)%),the proportion of NREM period ((74. 9±1. 6)%,(76. 9±1. 0)%),the sleep efficiency(( 82. 3± 2. 6)%,(89. 4± 3. 7)%) in the experi-mental group were significantly different before and after the intervention(P<0. 05). The differences value of the total sleep duration,NREM sleep proportion,deep sleep proportion and sleep efficiency before and after the intervention in the experimental group were significantly higher than those in the control group (P< 0. 05).
