Abstract

Objectives

The objective of this study is to assess the concordance and its association with sociocultural background of a four-question survey with accelerometry in a multiethnic adolescent population, regarding sleep components. Based on questions from the Pittsburgh Sleep Quality Index and adapted to a school context, the questionnaire focussed on estimating sleep onset time, wake-up time and sleep duration on both weekdays and weekends. This subjective survey was compared with accelerometry data while also considering the influence of sociocultural factors (sex, place of living, ethnic community and socio-economic status).

Methods

Adolescents aged 10.5–16 years (n = 182) in New Caledonia completed the survey and wore an accelerometer for seven consecutive days. Accelerometry was used to determine sleep onset and wake-up time using validated algorithms. Based on response comparison, Bland–Altman plots provided agreement between subjective answers and objective measures. We categorized participants' answers to the survey into underestimated, aligned and overestimated categories based on time discrepancies with accelerometry data. Multinomial regressions highlighted the sociocultural factors associated with discrepancies.

Results

Concordance between the accelerometer and self-reported assessments was low particularly during weekends (18%, 26% and 19% aligned for onset sleep time, wake-up time and sleep duration respectively) compared with weekdays (36%, 53% and 31% aligned, respectively). This means that the overall concordance was less than 30%. When considering the sociocultural factors, only place of living was associated with discrepancies in onset sleep time and wake-up time primarily on weekdays. Rural adolescents were more likely to overestimate both onset sleep time (B = −1.97, p < 0.001) and wake-up time (B = −1.69, p = 0.003).

Conclusions

The study found low concordance between self-assessment and accelerometry outputs for sleep components. This was particularly low for weekend days and for participants living in rural areas. While the adapted four-item questionnaire was useful and easy to complete, caution should be taken when making conclusions about sleep habits based solely on this measurement.

太平洋岛屿国家和地区青少年睡眠成分的自我报告和加速度测量：探索社会文化背景的作用

研究目的本研究的目的是评估在多种族青少年群体中进行的有关睡眠成分的四问调查与加速度计的一致性及其与社会文化背景的关联。该问卷以匹兹堡睡眠质量指数中的问题为基础，并根据学校环境进行了调整，重点是估算平日和周末的睡眠开始时间、起床时间和睡眠持续时间。这项主观调查与加速度测量数据进行了比较，同时还考虑了社会文化因素（性别、居住地、民族社区和社会经济地位）的影响。方法新喀里多尼亚 10.5-16 岁的青少年（n = 182）完成了调查，并连续七天佩戴加速度计。加速度计采用经过验证的算法确定睡眠开始和醒来的时间。根据反应比较，布兰德-阿尔特曼图提供了主观答案与客观测量之间的一致性。根据与加速度测量数据的时间差异，我们将参与者的调查答案分为低估、一致和高估三类。多项式回归强调了与差异相关的社会文化因素。结果与平日（分别为 36%、53% 和 31%）相比，加速度计和自我报告评估之间的一致性较低，尤其是在周末（开始睡眠时间、起床时间和睡眠时间的一致性分别为 18%、26% 和 19%）。这意味着总体一致性低于 30%。在考虑社会文化因素时，只有居住地主要与平日开始睡眠时间和起床时间的差异有关。农村青少年更容易高估入睡时间（B = -1.97, p < 0.001）和起床时间（B = -1.69, p = 0.003）。结论该研究发现，自我评估与加速度计输出的睡眠成分之间的一致性较低。尤其是周末和居住在农村地区的参与者。虽然改编后的四项调查问卷有用且易于填写，但仅凭这一测量结果对睡眠习惯下结论时应谨慎。

期刊介绍： Child: care, health and development is an international, peer-reviewed journal which publishes papers dealing with all aspects of the health and development of children and young people. We aim to attract quantitative and qualitative research papers relevant to people from all disciplines working in child health. We welcome studies which examine the effects of social and environmental factors on health and development as well as those dealing with clinical issues, the organization of services and health policy. We particularly encourage the submission of studies related to those who are disadvantaged by physical, developmental, emotional and social problems. The journal also aims to collate important research findings and to provide a forum for discussion of global child health issues.
