Abstract

Objectives

To identify factors affecting early childhood sleep, and investigate the relationship between sleep and overweight/obesity in childhood.

Study Design

Data were collected using parental-completed questionnaires from N = 10.840 one-year-old children in the prospective ABIS-study (All Babies in Southeast Sweden), followed up until 8 years of age. Chi-squared test and Pearson Correlation were used to assess the relationship between covariates affecting the children's sleep. Subsequently, longitudinal mixed model analyses were used to predict the effect of different sleep dimensions (bedtime, sleep duration, sleep quality, and the number of awakenings) on BMI Z-scores.

Results

Children to parents born in Sweden, parents with higher education, non-single parents, non-smoking mothers during pregnancy, and children with fewer siblings, were more likely to have appropriate sleep habits at 1 year age. A greater number of awakenings and nocturnal feeds, and particularly later bedtime (β = −0.544, p < 0.0001) were linked to shorter sleep duration. Sleep duration early in life was negatively associated with BMI Z-scores (adjusted effect estimate [95% CI]: β = −0.09, [(−0.15) – (−0.03)], p = 0.005) later. In addition, higher birth weight, small size for gestational age, unhealthy food habits, children of mothers who smoked during pregnancy, and higher parental BMI resulted in higher BMI Z-scores.

Conclusion

The child's BMI Z-score increases by 0.09 units with every hour shorter sleep duration, indicating that short sleep duration might increase the risk of overweight and obesity in children. Parental educational interventions advising appropriate sleeping patterns should be considered when implementing strategies to combat the development of childhood obesity.

儿童睡眠和肥胖风险:一项对10000名瑞典儿童的前瞻性队列研究

目的了解儿童早期睡眠的影响因素，探讨儿童睡眠与超重/肥胖的关系。研究设计采用前瞻性abis研究(瑞典东南部所有婴儿)中N = 10.840名1岁儿童的父母填写的问卷收集数据，随访至8岁。采用卡方检验和Pearson相关来评估影响儿童睡眠的协变量之间的关系。随后，采用纵向混合模型分析来预测不同睡眠维度(就寝时间、睡眠持续时间、睡眠质量和醒来次数)对BMI z得分的影响。结果父母出生在瑞典、父母受过高等教育、非单亲父母、怀孕期间母亲不吸烟、兄弟姐妹较少的儿童在1岁时更有可能有适当的睡眠习惯。更多的醒来次数和夜间进食次数，特别是更晚的就寝时间(β = - 0.544, p < 0.0001)与更短的睡眠时间有关。生命早期的睡眠时间与随后的BMI z分数呈负相关(调整后的效应估计[95% CI]: β = - 0.09， [(- 0.15) - (- 0.03)]， p = 0.005)。此外，较高的出生体重、胎龄小、不健康的饮食习惯、母亲在怀孕期间吸烟的孩子以及父母的BMI较高都会导致较高的BMI z分数。结论睡眠时间每缩短1小时，儿童BMI Z-score升高0.09个单位，提示睡眠时间过短可能增加儿童超重和肥胖的风险。在实施对抗儿童肥胖发展的策略时，应考虑建议适当睡眠模式的父母教育干预措施。

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.
