Parental Education and Children's Sleep Disturbance: Minorities' Diminished Returns

Area of Science:

• Child development
• Sociology
• Public Health

Background:

• Parental education is linked to fewer childhood sleep problems.
• Minorities' Diminished Returns (MDRs) theory suggests socioeconomic resources have weaker health impacts for minority groups due to systemic inequities.
• Racial disparities in the protective effect of parental education on child sleep are not well understood.

Purpose of the Study:

• To investigate the association between parental education and children's sleep problems.
• To examine if this association varies by race/ethnicity, testing the MDRs theory.

Main Methods:

• Cross-sectional study of 11,718 American children aged 9-10 from the ABCD study.
• Parental education (independent variable) and children's sleep problems (dependent variable) were analyzed.
• Mixed-effects regression models were used, with race/ethnicity as an effect modifier.

Main Results:

• Parental education showed an association with children's sleep problems.
• This protective association was weaker in non-Latino Black and Latino families compared to non-Latino White families.
• A significant interaction between race/ethnicity and parental education confirmed these disparities.

Conclusions:

• The diminished protective effect of parental education on sleep problems for Black and Latino children aligns with MDRs theory.
• These findings suggest that racial inequities may exacerbate sleep problems in minority children.
• Worse sleep in middle-class minority children could contribute to increased health risks.
