摘要
目的 探究睡眠碎片化与中学女生体成分、血压的相关性,为预防睡眠碎片化所引起的健康危害提供参考依据。方法 2022年9月—2023年12月,采用分层整群随机抽样方法选取南阳市505名12~15岁女生为研究对象并进行匹兹堡睡眠质量量表(PSQI)调查,根据睡眠碎片化指数(SFI)四分位数将测试女生分为Q1~Q4组,采用体成分仪和传统汞式血压计测量体成分、血压,采用χ^(2)检验和线性回归分析对数据进行比较和分析。结果 南阳市12~15岁中学女生随着SFI的升高,体质量指数(BMI)、脂肪率、肌肉量、骨量、躯干脂肪率、收缩压、舒张压、PSQI总得分Q1~Q4组间差异均有统计学意义(F值分别为15.25,7.33,8.38,5.97,11.24,16.85,6.87,15.73,P值均<0.05),且SFI与BMI、脂肪率、躯干脂肪率、血压(收缩压/舒张压)呈正相关(β值分别为0.37,0.45,0.34,0.42,0.38),与肌肉量、骨量均呈负相关(β值分别为-0.35,-0.48)(P值均<0.05);χ^(2)趋势检验显示,随着SFI升高,高血压的检出率呈增高趋势(χ^(2)=42.75,P<0.05);χ^(2)检验显示不同四分位数组间高血压发生率差异有统计学意义(χ^(2)=14.16,P<0.05);调整检验水准后,Q1与Q4组(χ^(2)=10.77)、Q2与Q4组(χ^(2)=6.28)女生间的高血压发生率差异有统计学意义(P值均<0.008 3)。结论 中学女生睡眠碎片化与体成分、血压具有相关性,采取睡眠碎片化干预措施,对于保护中学女生健康是非常必要的。
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 Q1-Q4 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 usingχ^(2) tests and linear regression.Results Significant intergroup differences for Q1-Q4 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).Theχ^(2) trend test revealed a significant increase in hypertension detection rates with elevated SFI(χ^(2)=42.75,P<0.05).Theχ^(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 Q1and Q4(χ^(2)=10.77),Q2 and Q4 groups(χ^(2)=6.28)(both P<0.0083).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.
