Insights
Sleep problems are common in school-aged children and often persist from preschool years. Recognizing and addressing persistent childhood sleep issues is crucial for overall health and development.
Area of Science:
- Pediatric Health
- Sleep Medicine
- Developmental Psychology
Background:
- Childhood sleep disturbances are prevalent.
- Understanding the persistence of sleep problems from preschool to school age is vital for early intervention.
Purpose of the Study:
- To determine the prevalence of sleep problems in Finnish school-aged children.
- To assess the persistence of sleep problems from preschool to school age over a 4-year follow-up period.
Main Methods:
- Longitudinal study involving 481 children in a Finnish community sample.
- Parents completed the Sleep Disturbance Scale for Children questionnaire at preschool (3-6 years) and school age (7-11 years).
- Follow-up included questionnaires on family structure and socio-economic status.
Main Results:
- Sleep problems slightly decreased at the population level from preschool to school age.
- A significant persistence of sleep disorders was observed: 35% of preschool sleep disorder cases continued into school age (9% of the community sample).
- Children without preschool sleep problems rarely developed them later.
Conclusions:
- Sleep problems are common and persistent in children from preschool to school age.
- Persistent sleep problems require clinical attention due to potential links with somatic, cognitive, and psychiatric issues.
- Paediatric healthcare should focus on identifying and intervening in prolonged childhood sleep problems.
Objective:
To study the prevalence of various sleep problems at school age in a Finnish community sample and to evaluate the persistence of the sleep problems from the preschool age to school age in a 4-year follow-up.
Methods:
Parents completed the Sleep Disturbance Scale for Children questionnaire on their child's sleep during the preschool years (3-6 years) and again during the school years (7-11 years). At follow-up the parents also completed a questionnaire on family structure and socio-economic status.
Results:
The parents of 481 children completed the questionnaires during both the first study and the follow-up (girls 49%, boys 51%; mean age 9, range 7-11). At the population level, sleep problems slightly declined from preschool to school age (P < 0.05). However, sleep problems at preschool age showed a strong persistence to school age. At the follow-up, 35% of the children who were considered to have a sleep disorder at preschool age still suffered from it at school age. At the community level, this equates to 9% of the children. The children with no sleep problems at preschool age rarely developed sleep problems at school age.
Conclusions:
This study showed that various types of sleep problems are common at school age. Sleep problems persisted from preschool to school age at the individual level. It is important to recognize all types of sleep problems, especially persistent ones. Persistent sleep problems in children may cause and exacerbate other somatic, cognitive and psychiatric problems. Therefore, more attention should be focused on sleep problems in paediatric health care with interventions aimed particularly at children with prolonged sleep problems.
