Epidemiologic study the prevalence of hypertension in snoring in adults aged over 35 years in Kelamayi city

Abstract

Objective To study the prevalence of hypertension in snoring in adults aged over 35 years in Kelamayi city.and relationship among snoring,nocturnal desaturation and hypertension.Methods 1144 subjects (age≥35) were derived from the population living in three districts in Kelamayi city.All subjects were asked at home to answer questions about their snoring by himself or bed partner.They were asked to answer the questions concerniug snoring,hypertension history etc,and meaturing the height,weight,neck circumference,abdominal circumference,waistline and hip circumference.and home pulse oximeter testing.Results The body mass index [(26.7±3.9) kg/m2 vs (25.6±4.1) kg/m2],neck circumference [(36.5 ± 3.4)cm vs ( 35.6 ± 3.1)cm],abdominal circumference [(92.8 ± l1.3) cm vs (89.8±11.3)cm],the number of desaturations≥4％ per hour (ODI4)[(11.0±11.0) times/h vs(6.5±7.4) times/h],the mean nocturnal arterial oxygen saturation ( MSaO2 ) [( 92.8 ± 4.5 ) ％ vs (93.3±2.8)％],the nadir arterial oxygen saturation (LSaO2) [(82.6 ± 6.3)％ vs (84.0 ± 8.0)％],systolic BP(SBP)[(130.3±18.3)mm Hg vs (125.1±16.5)mm Hg] and diastolic BP (DBP)[(82.8±12.7) mm Hg vs (78.5±12.1) mm Hg] were significantly different bettween with and without snoring groups ( P ＜0.01).The body mass index [(26.7±4.1)kg/m2 vs (25.5±3.7)kg/m2],neck circumference [(36.4±3.4) cm vs (35.6±3.1)cm],abdominal circumference [(93.4±11.3) cm vs (88.4±10.8) cm].SBP[(130.2±17.8) mmHg vs(124.5±17.0) mm Hg]and DBP[(82.2±12.66)mm Hg vs (78.7±12.3) mm Hg] were significantly different bettween with and without nocturnal desaturation groups ( P ＜0.01),there are significant difference on the prevaleuce of hypertension between with and without snoring groups (32.9％ vs 20.2％)( P ＜0.01),there are significant difference on the prevalence of hypertension between with and without nocturnal desaturation (35.9％ vs 17.1％)( P ＜0.01).Conclusions The prevalence of hypertension of snoring in adults over 35 yr old was 32.9％in Kelamayi city,hypertension corrclated with snoring and nocturnal desaturation,snoring and nocturnal desaturation can to cause hypertension,that the disease needs better understanding and study.
