Abstract
Background: Stereotypies have been described in children with developmental disorders but their prevalence and characteristics in developmentally normal children is unknown. Objective: To estimate the prevalence of stereotypies in children without chronic diseases and describe their clinical and epidemiological characteristics.
Patients and Methods: A Cross-sectional study was performed. Mothers of children aged from birth to 12 years, who attended the outpatient clinic, answered survey questions.
Results: 406 surveys were completed; stereotypies were observed in 57% of patients, among the most frequent, finger sucking (21.8%) and nail biting (20%). A multivariate analysis identified that stereotypies are more likely in children with a history of stereotypy in parents, under stressful environments, and with mothers over 35 years old.
Conclusion: Stereo-typies showed a high prevalence in this study, most frequently in those children under stressful environments, mothers older than 35 years, and affected parents.
