Objectives Early life is a critical period to enhance the optimal child growth and development, and sleep is an essential influential factor as well as indicator of well-being. However, little is known about the relationship between sleep and length/height growth. This study aims to examine this association in infants and toddlers based on a national multicentre sample.
Methods A total of 1056 (males 54.5%) full term and healthy children aged 3-36 months were recruited through a multistage sampling strategy from 8 provinces in China from 2011 to 2013. Anthropometric data (length/height and weight) were conducted by experienced pediatricians, and the validated Chinese version of the Brief Infant Sleep Questionnaire (BISQ) was completed by parents/caregivers. Total sleep duration (TSD) was categorized as short, optimal and long according to the age-specific recommendations in 2015 from the National Sleep Foundation. Multivariable linear regression was used to evaluate the associations between TSD categories and length/height with adjustment for age, gender, birth weight, feeding methods, parental height, parental education, sampling sites and seasons which would affect the child sleep.
Results Mean age was 14.5 months (SD 9.5). Overall, 1.6% of children showed stunting growth, 16.3% had short TSD, and 4.0% had long STD. Compared to those children with optimal TSD, the length/height was 0.87cm (95% CI: -1.71, -0.03; p<0.04) shorter in children with long TSD and 0.12cm (95% CI: -0.58, 0.35; p>0.05) shorter in children with short TSD after adjusting for confounding factors, though the later did not reach statistical significance.
Conclusions In conclusion, although the effect size was very small, the short and long sleep duration were both negatively associated with body length/height for the infants and toddlers. And this topic warrant further examination with more objective measures in the prospective cohort studies.
