睡眠时间短与一系列不良的心理和身体健康结果有关。然而，这种风险可能会受到性别和种族/族裔等人口因素的影响。在一个不同的社区样本中，目前的研究检查了性别、种族/民族和客观测量的睡眠时间之间的关系，控制了选定的潜在混淆。参与者是300名社区成年人(50%是女性)，年龄在21岁到70岁之间，其中包括60%的非西班牙裔白人，15%的非西班牙裔黑人，19%的西班牙裔/拉丁裔，以及6%的其他人。作为一项更大规模研究的一部分，参与者在两个晚上佩戴运动记录仪来评估睡眠时间(两个晚上的平均值)。以性别和种族/民族作为分组变量，以年龄、收入和就业状况为协变量，采用双向协方差分析(ANCOVA)预测客观评估的总睡眠时间。男性的平均睡眠时间比女性少34分钟(p=0.002)。在控制了社会经济因素后，存在种族/民族交互作用的性别(p=0.030)。在男性中，西班牙裔比非西班牙裔白人少睡45分钟(p=.002)，比非西班牙裔白人少睡57分钟(p=.008)。在非西班牙裔白人(差异=−22.9；p=.016)和西班牙裔(差异=−77.1p<；.001)组中，男性的睡眠时间也明显少于女性。这项研究扩展了之前的研究，为日常生活中基于性别和种族/民族的客观睡眠时间差异提供了额外的证据。这些数据表明，与睡眠时间相关的风险在性别和种族/民族方面具有重要的模式；这种信息可用于定制预防工作。
Short sleep duration has been linked with a wide array of poor mental and physical health outcomes. Such risks, however, may be moderated by demographic factors such as gender and race/ethnicity. In a diverse community sample, the current study examined the relationship between gender, race/ethnicity and objectively measured sleep duration, controlling for select potential confounds. Participants were 300 community adults (50% female), aged 21 to 70 years, and included 60% non-Hispanic Whites, 15% non-Hispanic Blacks, 19% Hispanic/Latino, and 6% Other. As part of a larger study, participants wore an actigraphy device over two nights to assess sleep duration (averaged across both nights). Gender and race/ethnicity were used as grouping variables in a two-way analysis of covariance (ANCOVA) predicting objectively assessed total sleep time, with age, income and employment status as covariates. On average, males slept 34 min less than females (p=0.002). After controlling for socioeconomic factors, there was a gender by race/ethnicity interaction (p=0.030). Within males, Hispanics slept 45 min less than non-Hispanic Whites (p=.002) and 57 min less than non-Hispanic Others (p=.008). Males also slept significantly less than females within the non-Hispanic White (difference=−22.9; p=.016) and the Hispanic (difference=−77.1; p<.001) groups. Extending previous research, the current study provides additional evidence for differences in objective sleep duration based on gender and race/ethnicity in daily life. These data suggest that risk associated with sleep duration is patterned in important ways across gender and race/ethnicity; such information can be used to tailor prevention efforts.
