摘要

背景：充足的睡眠时间是预防儿童肥胖的一个因素，但时间的作用尚不清楚。目的：在一个大型儿科数据库中调查睡眠时间和睡眠时间与BMI的关系。方法：收集2019年1月至2023年12月就诊的29 409名2-18岁儿童的病历和调查数据（重复测量横断面设计）。考虑重复测量的Logistic和线性混合效应回归模型估计了超重/肥胖的几率和基于疾病预防控制中心的连续bmi年龄百分位数，每增加/晚睡一小时，中点（就寝时间和清醒时间的中位数）和就寝时间，调整了潜在的混杂因素并按年龄组分层。结果：在幼儿（2-5岁）中，较短的睡眠时间而非睡眠时间与较高的超重/肥胖几率相关（高21%的几率，95% CI: 3%至36%）。在儿童中期（6-12岁），较短的睡眠时间和较晚的睡眠时间与较高的超重/肥胖几率相关（18%,95% CI = 9%, 26%; 32%, 95% CI = 17%, 49%）。在青少年（13-18岁）中，睡眠中点每晚一个小时，超重/肥胖的几率就会增加12%（95%置信区间：1%至23%）。线性模型相似。结论：年轻时较短的睡眠时间和青春期较晚的睡眠时间与较高的BMI有关。

Role of Sleep Duration and Timing on Paediatric BMI Across Childhood and Adolescence: Do Both Matter?

Background: Adequate sleep duration is a prevention factor for paediatric obesity, but the role of timing is still unclear.

Objectives: To investigate associations of sleep duration and timing with BMI in a large paediatric database.

Methods: Medical chart and survey data were collected from 29 409 children aged 2-18 years who attended well-child visits between Jan 2019 and Dec 2023 (repeated-measures cross-sectional design). Logistic and linear mixed effects regression models accounting for repeated measures estimated odds of overweight/obesity and continuous BMI-for-age CDC-based percentiles for each additional/later hour of sleep duration, midpoint (median of bedtime and wake time), and bedtime, adjusted for potential confounders and stratified by age groups.

Results: Among young children (2-5 years), shorter sleep duration but not sleep timing was related to higher odds of overweight/obesity (21% higher odds with 95% CI: 3% to 36%). In mid-childhood (6-12 years), shorter sleep duration and later midpoint were associated with higher odds of overweight/obesity (18%, 95% CI = 9%, 26%; 32%, 95% CI = 17%, 49%). Among adolescents (13-18 years), each hour of later sleep midpoint equated to 12% higher odds of living with overweight/obesity (95% CI: 1% to 23%). Linear models were similar.

Conclusions: Shorter sleep duration at younger ages and later sleep timing in adolescence were associated with higher BMI.

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
