Examine the distribution of symptoms and risk factors, and estimate the prevalence of obstructive sleep apnea (OSA) among Māori and non-Māori New Zealanders.
Mail-out survey to a stratified random sample from the electoral roll of 10,000 people aged 30-59 y, and overnight MESAM IV monitoring during sleep of a similarly aged stratified random sample of 364 people from the Wellington electoral roll.
Nationwide survey of OSA symptoms (71% response rate) and regional home-based measurement of respiratory disturbance index (RDI, 4% oxygen desaturations/h of sleep, plus bursts of snoring or > or = 10/min increase in heart rate).
Sample designs aimed for equal numbers of Māori and non-Māori participants, men and women, and participants in each decade of age.
N/A.
Māori were more likely than non-Māori to report OSAS risk factors and symptoms. After controlling for sex and age, Māori were 4.3 times more likely to have RDI > or = 15 (95% CI = 1.3-13.9). Ethnicity was not an independent risk factor after controlling for body mass index (BMI) and neck circumference. The prevalence of OSAS (RDI > or = 5 and ESS > 10) was conservatively estimated to be 4.4% for Māori men, 4.1% for non-Māori men, 2.0% for Māori women, and 0.7% for non-Māori women.
The national survey and the regional monitoring study indicate a higher prevalence of OSA among Māori and among men. The higher prevalence among Māori appears to be attributable to recognized risk factors, notably body habitus. In addition to increased prevention and treatment services, strategies are needed to reduce ethnic disparities in OSAS prevalence.
研究症状和风险因素的分布情况，并估计毛利人和非毛利新西兰人阻塞性睡眠呼吸暂停（OSA）的患病率。
对从10000名年龄在30 - 59岁的选民名单中分层随机抽取的样本进行邮寄调查，并对来自惠灵顿选民名单的364名年龄相仿的分层随机样本在睡眠期间进行夜间MESAM IV监测。
全国范围内对OSA症状进行调查（回复率71%），并在区域内进行基于家庭的呼吸紊乱指数（RDI，每小时睡眠中4%的血氧饱和度下降，加上打鼾发作或心率每分钟增加≥10次）测量。
样本设计旨在使毛利人和非毛利参与者、男性和女性以及每个年龄段的参与者数量相等。
无。
毛利人比非毛利人更有可能报告OSAS风险因素和症状。在控制性别和年龄后，毛利人RDI≥15的可能性是非毛利人的4.3倍（95%可信区间 = 1.3 - 13.9）。在控制体重指数（BMI）和颈围后，种族不是一个独立的风险因素。保守估计，毛利男性OSAS（RDI≥5且ESS>10）的患病率为4.4%，非毛利男性为4.1%，毛利女性为2.0%，非毛利女性为0.7%。
全国性调查和区域监测研究表明，毛利人和男性中OSA的患病率较高。毛利人患病率较高似乎归因于公认的风险因素，尤其是体型。除了增加预防和治疗服务外，还需要采取策略来减少OSAS患病率方面的种族差异。
