The prevalence of neck-shoulder pain, back pain and psychological symptoms in association with daytime sleepiness – a prospective follow-up study of school children aged 10 to 15

Abstract

Abstract Background and aims Chronic and recurrent pain is prevalent in adolescents and generally girls report more pain symptoms than boys. Also, pain symptoms and sleep problems often co-occur. Pain symptoms have negative effects on school achievement, emotional well-being, sleep, and overall health and well-being. For effective intervention and prevention there is a need for defining factors associated with pain symptoms and daytime sleepiness. The aim of this longitudinal study was to investigate the prevalence and association between neck-shoulder pain, back pain, psychological symptoms and daytime sleepiness in 10-, 12- and 15-year-old children. This study is the first that followed up the same cohort of children from the age of 10 to 15. Methods A cohort study design with three measurement points was used. Participants (n=568) were recruited from an elementary school cohort in a city of 1,75,000 inhabitants in South-Western Finland. Symptoms and daytime sleepiness were measured with self-administered questionnaires. Regression models were used to analyze the associations. Results Frequent neck-shoulder pain and back pain, and psychological symptoms, as well as daytime sleepiness, are already common at the age of 10 and increase strongly between the ages 12 and 15. Overall a greater proportion of girls suffered from pain symptoms and daytime sleepiness compared to boys. Daytime sleepiness in all ages associated positively with the frequency of neck-shoulder pain and back pain. The more that daytime sleepiness existed, the more neck-shoulder pain and back pain occurred. Daytime sleepiness at the age of 10 predicted neck-shoulder pain at the age of 15, and back pain at the age of 10 indicated that there would also be back pain at the age of 15. In addition, positive associations between psychological symptoms and neck-shoulder pain, as well as back pain, were observed. Subjects with psychological problems suffered neck-shoulder pain and back pain more frequently. Conclusions This study is the first study that has followed up the same cohort of children from the age of 10 to 15. The studied symptoms were all already frequent at the age of 10. An increase mostly happened between the ages of 12 and 15. Moreover, the self-reported daytime sleepiness at the age of 10 predicted neck-shoulder pain at the age of 15. More attention should be paid to the daytime sleepiness of children at an early stage as it has a predictive value for other symptoms later in life. Implications School nurses, teachers and parents are in a key position to prevent adolescents’ sleep habits and healthy living habits. Furthermore, the finding that daytime sleepiness predicts neck-shoulder pain later in adolescence suggests that persistent sleep problems in childhood need early identification and treatment. Health care professionals also need take account of other risk factors, such as psychological symptoms and pain symptoms. The early identification and treatment of sleep problems in children might prevent the symptoms’ development later in life. There is a need for an individuals’ interventions to treat adolescents’ sleep problems.
