Resumen
Abstract
Objectives: While altered sleep patterns (ie, low sleep time) have been studied and
reported in adults as a new cardiometabolic risk factor, less information is available
on how sleep patterns impact children of different ethnicities. The aim of this study
was to compare the levels of blood pressure and other cardiometabolic risk factors
in relation to different levels of sleep time in schoolchildren of Amerindian Mapuche
or European-ancestry of Southern Chile.
Methods: In a cross-sectional study, 540 Chilean schoolchildren (6-13 years) were
divided into two ethnic groups (n = 119 Mapuche Amerindians and n = 421
European-ancestry). Groups were analyzed according to sleep time per day as registered
by parents' report and distributed into quartile categories of sleep time:
Mapuche (quartile 1 [Q1] ≥10.0 h, n = 34; Q2 9.5-10.0 h, n = 29; Q3 8.5-9.0 h,
n = 31; and Q4 ≤ 8.5 h, n = 25), and European (Q1, n = 99; Q2, n = 77; Q3,
n = 144; Q4, n = 101). The main cardiovascular parameters (systolic [SBP] and
diastolic blood pressure) were complemented with anthropometric/body composition
(body mass, body mass index [BMI], waist circumference, fat mass, muscle
mass, lean mass), cardiorespiratory (heart rate rest, oxygen saturation), and muscle
strength (handgrip of dominant and non-dominant arm) outcomes.
Results: From Q1 and across Q2, Q3, and Q4, there was an increase in delta mean
SBP in both Mapuche (Δ +17.6 mm Hg) and European (Δ +7.3 mm Hg)
schoolchildren with 30-90 min of decreased sleep time (using ≥10 h as reference
in Q1). The tendency for worsening of other cardiometabolic risk factors was
maintained for delta mean BMI (Δ +2.6 kg/m2), waist circumference (Δ +12 cm),
and fat mass (Δ +8.3%) in Mapuches, whereas European peers showed only worsened
waist circumference (Δ +6 cm) across Q2, Q3, and Q4 in comparison with
reference Q1. There was also a higher prevalence of hypertension in Mapuche
(31.1%) compared to in European schoolchildren (17.6%).
