Abstract

Background

Cross-sectional research has suggested associations between diet, sleep and obesity, with sparse longitudinal research.

Objectives

To identify longitudinal mechanistic associations between sleep, diet and obesity.

Methods

We used longitudinal data from a sample of Black adolescent girls. At T1 (enrolment), 6 months (T2) and 18 months (T3), we estimated sleep duration and quality (7-day accelerometry), diet quality (Healthy Eating Index [HEI-2020]) and body mass z-scores (zBMI) from measured height and weight. Longitudinal mediation using structural equation models examined the mechanistic roles of sleep, diet quality and zBMI.

Results

At enrolment, girls (n = 441) were mean age 12.2 years (±0.71), 48.3% had overweight/obesity, and mean HEI 55.8 (±7.49). The association between sleep and diet quality did not vary over time. Sleep duration at T1 was not associated with diet quality at T2 nor was diet associated with zBMI at T3. The bootstrapped indirect effect was not significant. Sleep quality at T1 was not associated with diet quality at T2 nor was diet associated with zBMI at T3. The bootstrapped indirect effect was not significant.

Conclusions

Diet was not a mediator between sleep and obesity. Study strengths are the longitudinal design and direct measures of sleep and zBMI among a homogeneous sample.

评估黑人少女睡眠、饮食质量与BMI z-score之间的纵向关联。

背景：横断面研究表明饮食、睡眠和肥胖之间存在关联，而纵向研究较少。目的：确定睡眠、饮食和肥胖之间的纵向机制联系。方法：我们使用了一个黑人少女样本的纵向数据。在T1（入组）、6个月（T2）和18个月（T3）时，我们根据测量的身高和体重估计睡眠时间和质量（7天加速度计）、饮食质量（健康饮食指数[HEI-2020]）和体重z分数（zBMI）。采用结构方程模型纵向中介检验睡眠、饮食质量与zBMI的作用机制。结果：入组时，女孩（n = 441）平均年龄12.2岁（±0.71），48.3%超重/肥胖，平均HEI为55.8（±7.49）。睡眠和饮食质量之间的关系并没有随着时间的推移而变化。T1时的睡眠时间与T2时的饮食质量无关，T3时的饮食与zBMI也无关。自举间接效应不显著。T1时的睡眠质量与T2时的饮食质量无关，T3时的饮食与zBMI也无关。自举间接效应不显著。结论：饮食不是睡眠和肥胖之间的中介。研究的优势在于纵向设计和在同质样本中直接测量睡眠和zBMI。

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.
