Abstract Introduction Healthy sleep is crucial for children's development. The literature suggests that higher parental education is associated with longer child sleep duration. However, little is known about how family education level affects children’s sleep patterns in Chile. We aimed to investigate the relationship between parental education level and sleep patterns and sleep duration during the week and on weekends. Methods Two hundred and fifty-eight participants (6-13 years; 50% girls) were included in this cross-sectional study. Data collected were parent-reported and included: educational level of the household head, categorized as no schooling or primary school, secondary school, technical or higher (graduate) college degree, bedtime, midpoint of sleep and sleep duration on weekdays and weekends. General linear models were tested to calculate adjusted differences between parental education level categories, adjusted for age and gender, followed by a Tukey post hoc test. Results We found that higher parental education level was significantly associated with advancing children’s bedtime on weekends (P = 0.007). Participants whose parents had a secondary school degree postponed their weekend bedtime by 0.36 hours (95% CI: 0.11, 0.61) compared to those whose parents had a technical or higher college degree. We also found that higher parental education level was significantly associated with advancing children’s weekend midpoint of sleep (P = 0.044). Specifically, the weekend midpoint of sleep was earlier (−0.29 h; 95% CI: −0.06, −0.53) for participants whose parents had a technical or higher college degree than for parents with a secondary school degree. Surprisingly, we found that lower parental education was associated with children sleeping longer on weekends (P = 0.026). In detail, participants whose parents had no schooling or primary education had 0.45 h longer weekend sleep duration (95% CI: 0.04, 0.87) compared to those whose parents had secondary school level. Conclusion Higher parental education level was associated with earlier weekend sleep patterns in children. However, lower parental education levels were associated with children sleeping longer on weekends. These results could be useful for the development of parenting programs targeting different levels of education to promote optimal sleep duration and time, as well as the well-being of Chilean children.
