Abstract:
Objective:To investigate the correlation between sleep fragmentation and body composition/blood pressure in female students of middle school, so as to provide theoretical guidance for preventing health risks associated with sleep fragmentation.
Methods:From September 2022 to December 2023, 505 female students aged 12-15 years in Nanyang City were selected through stratified cluster random sampling and conducted Pittsburgh Sleep Quality Index(PSQI) survey. Participants were divided into Q 1- Q 4 groups based on sleep fragmentation index (SFI) quartiles. Body composition and blood pressure measurements were measured by adopting body composition analyzer and traditional mercury sphygmomanometer, and data were analyzed using χ 2 tests and linear regression.
Results:Significant intergroup differences for Q 1- Q 4 were observed with increasing SFI levels for body mass index(BMI), fat percentage, muscle mass, bone mass, trunk fat percentage, systolic blood pressure, diastolic blood pressure, and PSQI total scores ( F =15.25,7.33,8.38,5.97,11.24,16.85,6.87,15.73, all P <0.05). SFI showed positive correlations with BMI, fat percentage, trunk fat percentage, and blood pressure( β =0.37,0.45,0.34,0.42,0.38), but negative correlations with muscle mass and bone mass( β =-0.35,-0.48) (all P <0.05). The χ 2 trend test revealed a significant increase in hypertension detection rates with elevated SFI ( χ 2=42.75, P <0.05). The χ 2 testing demonstrated statistically significant differences in hypertension incidence among different quartiles groups ( χ 2=14.16, P <0.05). After adjusting the significance level, hypertension incidence differences remained significant between Q 1and Q 4 ( χ 2=10.77), Q 2 and Q 4 groups ( χ 2=6.28) (both P <0.008 3).
Conclusions:Sleep fragmentation correlates significantly with body composition and blood pressure indicators in female students of middle school. Implementing sleep fragmentation interventions is essential for safeguarding female students health in middle school.
