Prevalence of Sleep Disorders Among Children 4 - 6 Years Old in Tehran Province, Iran

Epidemiology of Sleep Disturbances Among Primary School Students in Kerman, Iran, in 2019

Primary sleep disturbances are common in both children and adults and can lead to cognitive problems and educational and psychological disorders. In this study, we evaluated the epidemiology of sleep disturbances among children in Kerman, Iran, in 2019. This cross-sectional study was done in 2019 with 561 children in elementary schools of Kerman, Iran. Data were collected by a Pittsburgh Sleep Quality Index (PSQI) questionnaire that was filled out by parents and analyzed statistically. A total of 561children with a mean age of 9.54 ± 1.55 years were enrolled. The ratio of boys to girls was 1.01 and consistent across age groups. The prevalence of sleep disturbances in this population study was 26.7% (150 patients); 51.3% of them were girls. Sleep disturbances were associated with mothers' lower education level and parents' higher job positions (P < .05). This study showed the relatively high prevalence of sleep disturbances among children in this region. It can be reduced by a program such as sleep training or by promoting the level of parents' education. We recommend some educational programs and preschool screening to evaluate sleep disturbances and educating the parents to increase their responsiveness.

Effects of l-Carnosine Supplementation on Sleep Disorders and Disease Severity in Autistic Children: A Randomized, Controlled Clinical Trial

Sleep disorders are frequently reported in autistic patients. Evidences suggest that increased oxidative stress and reduced antioxidants may play a major role in the pathogenesis of these disorders. Carnosine acts as an antioxidant, antitoxic and neuroprotective agent. The aim of this trial study was to examine the effects of carnosine supplementation on the sleep disorders and severity of autism core symptoms in autistic patients. In this double-blind, randomized clinical trial, 43 autistic patients (31 boys and 12 girls; aged 4 to 16 years) were divided into two groups of carnosine and control that received 500 mg of carnosine and 500 mg of placebo per day for 2 months, respectively. Sleep disorders were measured using Children's Sleep Habits Questionnaires. Gilliam Autism Rating Scale 2 was used to assess the effects of carnosine supplementation on the autism severity. Carnosine supplementation did not change anthropometric indices (p > 0.05) and showed no effect on autism severity (p > 0.05), whereas it significantly reduced sleep duration (p = 0.04), parasomnias (p = 0.02) and total sleep disorders score by 7.59% (p = 0.006) when compared with the control group. The results suggest that carnosine supplementation could be effective in improving sleep disturbances, in particular sleep duration and parasomnias subscales.

Comparison of the Quality of Sleep and Intensity of Headache between Migraine, Tension Headache, and Healthy Children

OBJECTIVES

Headache and sleep problems are commonly reported in children, and both can adversely impact the child's life. We aimed to compare the sleep quality and intensity of headache between school-age children with migraine as well as tension headache and healthy children.

MATERIALS & METHODS

In this cross-sectional study, 198 children 6-12 yr old in three groups were enrolled from Aug 2015 to Mar 2016. Migraine and tension headache groups from the Outpatient Clinic of Imam Khomeini of Hamadan, western Iran and healthy group from elementary schools were randomly selected (66 children in each group). Data were collected using demographic questionnaire, Child Sleep Habits Questionnaire (CSHQ), Numeric Scale of Pain Intensity and Wong-Baker Faces Pain Rating Scale. The data were analyzed using SPSS by descriptive statistic and multivariate ANOVA, one way ANOVA, Chi-square, Kruskal-Wallis and linear regression tests.

RESULTS

Approximately, 45.5% of children with migraine and 37.9% of them with tension headache had experienced severe headache. Only a significant relationship was seen between mean scores of headache intensity and sleep quality in migraine group (P<0.05). There was a significant difference in mean scores of sleep quality among three groups (P<0.001).

CONCLUSION

The children with migraine experienced more unsuitable sleep in duration of severe headache. Highlighting the co-morbidity between intensity of headache and sleep problem of children with migraine and tension headache is important to improve treatment strategies and to know the impact of headache on their normal life.
