To investigate sexual behaviours, types and frequencies, among Swedish children in the age group of 7-13 years, as observed and reported by their parents and to give professionals in different areas a greater knowledge of sexual behaviour among younger school children. Methods: The parents of 418 children answered questionnaires about their child’s behaviour, both general and sexual, and about their own attitudes. Results: We found that most sexual behaviours we asked about were reported by the parents as common, and are in part related to, or vary with, age and gender. A small number of sexual behaviours often referred to as problematic behaviour were found to be very unusual in this normative group of Swedish children.Behaviours usually referred to as sexualized and problematic were rare in this normative sample of children at 7-13 years of age. The results are of importance for clinicians’ evaluation of sexual behaviours reported by parents.
