The Prevalence of Parasomnias in Preadolescent School-aged Children: a Turkish Sample

Abstract

These results suggest that the prevalence of parasomnias was high in the 9- and 10-year-old age groups. Parasomnias are associated with a history of physical illness and neurobehavioral abnormalities.

Factors affecting nightmares in children: parents’ vs. children’s ratings

“…The absolute prevalence rates obtained in this study lies within the range of figures reported in the literature, nevertheless immediate comparison to other studies is not possible because each study used different definitions of nightmares, for example, [3] applied the complete criteria of the nightmare disorder of the DSM IV [4]. In addition, answering categories differed across the studies: In this study sometimes/often were presented to the participants whereas in the Simonds and Parraga [36] study the cutoff was once a week.…”

“…Many large-scaled surveys [3,30,36,41] are based on questionnaires or interviews completed by the child's parents. Several studies [17,23,24,[26][27][28], however, reported a marked underestimation of nightmare occurrence in the parents' responses in comparison to the answers of the child, so that epidemiological studies based on data obtained from the parents have to be interpreted with caution.…”

Association of infantile bruxism and the terminal relationships of the primary second molars

“…1,3,[16][17][18][19] The literature has demonstrated a significant frequency of this habit compared with temporomandibular dysfunctions, which are less prevalent in this age group. 12 However, there are studies that have found lower frequencies, ranging from 5.9% 1,20,21 to 11%. 8,15 The origin of these differences regarding childhood bruxism is assumed to potentially be related to the lack of methodological uniformity in the studies, cultural differences existent among countries, 21,22 or even by the variety in the age groups studied.…”

Development and validation of the Sleep Disturbances Scale for School-age Children

“…9,10 Parasomnias also represent an important complaint, between 6.2 and 14.4%,the more frequent of them being night terrors, somniloquy, enuresis and bruxism. [11][12][13] Respiratory problems during sleep can occur up to 7.5%, 14 while sleep movement disorders, such as restless legs syndrome and periodic limb movement, occur between 2 and 23%. 15,16 Overall, sleep disorders could affect more than 40% of children.…”
