A cross-sectional prevalence study was done in four primary care clinics (two rural and two urban sites) and four Native American clinics serving members of the Chippewa, Sioux, Hidasta, Arikara, and Mandan tribes, all in North Dakota, to determine the prevalence of prone, supine, and side sleeping position in white and Native American infants. Questionnaires for 325 infants (259 whites and 66 Native Americans) between birth and 6 months of age were completed by the infants' mothers. They reported that 69 percent of the infants slept prone, 17 percent slept supine, and 14 percent slept on their side. Native American infants, who are at 3.2 times the risk of Sudden Infant Death Syndrome compared with other North Dakota infants, slept prone 46.9 percent of the time compared with 74.4 percent of white infants (chi 2 = 23.61; 1 df; P < .0001). No differences were observed in the prevalence of the side sleeping position. Eighteen percent of the infants slept in the position reported due to advice from a physician or nurse, 8 percent of the infants slept with more than two blankets, and 5 percent slept with a pillow. Native American infants in North Dakota did not have a higher prevalence of exposure to prone sleeping position.
在北达科他州的四家初级保健诊所（两家农村诊所和两家城市诊所）以及四家为齐佩瓦族、苏族、希达萨族、阿里卡拉族和曼丹族成员服务的美国原住民诊所开展了一项横断面患病率研究，以确定白人和美国原住民婴儿中俯卧、仰卧和侧卧睡眠姿势的患病率。由婴儿母亲填写针对325名出生至6个月大婴儿（259名白人婴儿和66名美国原住民婴儿）的调查问卷。她们报告称，69%的婴儿俯卧睡眠，17%仰卧睡眠，14%侧卧睡眠。与其他北达科他州婴儿相比，美国原住民婴儿患婴儿猝死综合征的风险是其3.2倍，其中46.9%的时间俯卧睡眠，而白人婴儿这一比例为74.4%（卡方=23.61；自由度为1；P<0.0001）。侧卧睡眠姿势的患病率未观察到差异。18%的婴儿因医生或护士的建议而保持报告的睡眠姿势，8%的婴儿睡觉时盖着两条以上毯子，5%的婴儿睡觉时使用枕头。北达科他州的美国原住民婴儿俯卧睡眠姿势的暴露率并不更高。
