Sleep duration and risk of high blood pressure in adolescents: a cross-sectional study from the Thai National Health Examination Survey VI, 2020 (NHES-VI)
摘要
Sleep duration has been shown to affect blood pressure, yet conflicting results persist. The present study aimed to investigate whether sleep duration was associated with high blood pressure in adolescents from the Thai National Health Examination Survey, VI (2020).
Materials and methodsThe survey was a nationwide, cross-sectional survey that used a multistage, stratified sample of the Thai population in both urban and rural areas across 5 regions, including Bangkok, Northern, Central, North-eastern, and Southern regions. Data from 4053 adolescents (2,029 females) aged 10–19, including demographic data, blood pressure, fasting lipid and glucose levels, sleep duration, and outdoor activity time, were collected. High blood pressure was diagnosed using the 2017 American Academy of Pediatrics guidelines. The results are presented as odds ratios (95% CI, p-values) for logistic regression and β coefficient (95% CI, p-values) for linear regression.
ResultsThe prevalence of high blood pressure was about 10% (weighted prevalence of 12.6%). Average sleep duration was 8.65 ± 1.28 h. The high blood pressure group had a higher body mass index (BMI), higher triglycerides (TG), longer weekday sleep duration, and lower high-density lipoprotein cholesterol than the normotensive group. In the multivariable logistic regression, BMI and TG were independently associated with high blood pressure, with ORs of 1.15 (95% CI: 1.11–1.20, p-value < 0.001) and 1.003 (95% CI 1.000-1.006, p-value = 0.048), respectively. Although sleep duration was not associated with high blood pressure (OR = 0.99, 95% CI 0.87–1.13), it was positively associated with systolic blood pressure in a multivariable linear regression model (β = 0.41, 95% CI 0.064– 0.764, p-value = 0.023).
ConclusionsThe prevalence of high blood pressure was about 10% in Thai adolescents. Although longer sleep duration was associated with higher systolic blood pressure, its effect was modest.
