ASSOCIATION BETWEEN CHILDREN’S SLEEP HABITS AND BLOOD PRESSURE AT SIX YEARS OF AGE

Introdução

Sleep habits play an important role on health maintenance and prevention of non-communicable chronic diseases in childhood and adulthood.

Objetivo

To evaluate the effect of sleep habits on blood pressure of six-year-old children.

Métodos

This research is a part of a bigger study denominated Predictors of Maternal and Infant Excess Body Weight – PREDI Study that was performed in Joinville-SC, Brazil. Data were collected at the homes of mothers and children that participated in the third follow-up of the PREDI Study in 2018. Sleep habits of the children were obtained by self-reports of the mothers by using the “Inventory of Sleep Habits for Preschool Children”. Children’s Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) were measured by a health professional through the auscultatory method and according to the “2017 Clinical Practice Guideline for Screening and Management of High Blood Pressure in Children and Adolescents”. Instructional therapeutic play was used as a strategy to avoid embarrassment to the children and to facilitate blood pressure assessment by the health professional.

Resultados

Of the 178 children that participated in the study, 21 (11.8%) presented elevated SBP (≥P90). Among these children, there was a greater prevalence poor sleep quality (57.1%). Additionally, children classified as having inadequate sleep habits showed significantly greater mean of SBP in comparison to children with adequate sleep habits, 61.5mmHg e 52.8mmHg respectively. The logistic regression analysis revealed that children with inadequate sleep habits had greater odds of having SBP≥P90 when compared to children with adequate sleep habits even after adjustment for nutritional status and years of education (OR=5.3, 95%CI=2.0-13.9, p=0.001).

Conclusões

Children with inadequate sleep habits have greater odds of developing high blood pressure at six years of age. Taking care of sleep quality in preschool age is essential to avoid the development of chronic-degenerative diseases that can last until adulthood.
