Sleep characteristics in Brazilian children and adolescents: a population-based study.

ABSTRACT:

Objective/background

To evaluate sleep characteristics in Brazilian children and adolescents aged 0-19 years and determine the prevalence of sleep disturbances (SDs) and their association with regional differences and socioeconomic status (SES).

Patients/methods

The target population was divided into three age groups: 0-3 years, 4-12 years, and 13-19 years. An online questionnaire based on Brazilian versions of instruments for sleep assessment was made available to participants from 2014 to 2017. Sleep habits were characterized following the recommendations of the instruments and of the National Sleep Foundation. Data were evaluated by bivariate analyses and logistic regression analyses (p ≤ 0.05).

Results

A total of 1180 respondents were included, representative of all Brazilian regions and SES levels. Inadequate bedtime habits and total sleep time below the recommended levels were observed in all age groups. Overall SD prevalence was 25.5%. Increased risk of SDs was associated with a current health problem in children aged 0-3 years, with hospitalization after birth and sleeping in parents' bed in children aged 4-12 years, and with medication use and playing video games/using the cell phone before sleep in adolescents. There was no significant difference in SD rates between the regions. There was an increased risk of SDs in children with low SES (0-3 years), lower middle SES (4-12 years), and high SES (13-19 years).

Conclusions

Brazilian children and adolescents overall present inadequate sleep habits and sleep duration lower than recommended. SDs increased with age, reaching a peak in adolescence, with an influence of SES on these disturbances.

Project description:BackgroundData regarding the geographical distribution of cases and risk factors for COVID-19 death in children and adolescents are scarce. We describe the spatial distribution of COVID-19 cases and deaths in paediatric population and their association with social determinants of health in Brazil.MethodsThis is a population-based ecological study with a spatial analysis of all cases and deaths due to COVID-19 in Brazil among children and adolescents aged 0-19 years from March 2020 to October 2021. The units of analysis were the 5570 municipalities. Data on COVID-19 cases and deaths, social vulnerability, health inequities, and health system capacity were obtained from publicly available databases. Municipalities were stratified from low to very high COVID-19 incidence and mortality using K-means clustering procedures, and spatial clusters and relative risks were estimated using spatial statistics with Poisson probability models. The relationship between COVID-19 estimates and social determinants of health was explored by using multivariate Beta regression techniques.FindingsA total of 33,991 COVID-19 cases and 2424 deaths among children and adolescents aged 0-19 years were recorded from March 2020 to October 2021. There was a spatial dependence for the crude mortality coefficient per 100,000 population in the paediatric population aged 0-19 years (I Moran 0·10; P < 0·001). Forty municipalities had higher mortality rates, of which 20 were in states from the Northeast region. Seven spatial clusters were identified for COVID-19 mortality, with four clusters in the Northeast region and three in the North region. Municipalities with higher social inequality and vulnerability had higher COVID-19 mortality in the paediatric population.InterpretationThe main clusters of risk for mortality among children and adolescents were identified in municipalities in the North and Northeast regions, which are the regions with the worst socioeconomic indicators and greatest health disparities in the country. Our findings confirmed the higher burden of COVID-19 for Brazilian paediatric population in municipalities with higher social inequality and vulnerability and worse socioeconomic indicators. To reduce the burden of COVID-19 on children, mass immunisation is necessary.FundingNone.
