Summary
Adolescent sleep assessments show poor agreement between subjective reports and actigraphy, especially in boys. This highlights the need for careful interpretation of sleep data in this age group.
Area of Science:
- Adolescent sleep medicine
- Chronobiology
- Biomedical data analysis
Background:
- Limited studies exist on sleep measurement agreement in adolescents.
- Subjective sleep reports and actigraphy are common assessment tools.
- Understanding discrepancies is crucial for accurate sleep evaluation.
Purpose of the Study:
- To compare self-reported sleep duration with actigraphy in adolescents.
- To investigate gender differences in sleep measurement agreement.
- To utilize a novel survival agreement plot for data visualization.
Main Methods:
- 37 adolescents (12-17 years) participated.
- Sleep duration was assessed via questionnaires and 7-day actigraphy.
- Statistical analyses included Bland-Altman plots, intraclass correlation, and survival agreement plots.
Main Results:
- A significant difference of approximately one hour was found between subjective and actigraphy sleep duration (p < 0.01).
- Boys reported sleep duration discrepancies of 1.9 hours, compared to 0.5 hours in girls.
- Intraclass correlation coefficients indicated poor agreement overall, with higher correlation in girls (0.43) than boys (0.06).
Conclusions:
- Findings align with previous research indicating poor agreement between subjective sleep measures and actigraphy.
- This is the first study to examine this concordance in Brazilian adolescents.
- Results emphasize cautious use of subjective sleep measures in adolescents, particularly boys.

01:13Insufficient Sleep and Sleep Deprivation
1.2K
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:30Socioemotional Experience and Gender Development
366
Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
