OBJECTIVE: The objective of this study was to estimate the incidence of positional plagiocephaly in infants 7 to 12 weeks of age who attend the 2-month well-child clinic in Calgary, Alberta, Canada. %26lt;br%26gt;METHODS: A prospective cohort design was used to recruit 440 healthy full-term infants (born at %26gt;= 37 weeks of gestation) who presented at 2-month well-child clinics for public health nursing services (eg, immunization) in the city of Calgary, Alberta. The study was completed in 4 community health centers (CHCs) from July to September 2010. The CHCs were selected based on their location, each CHC representing 1 quadrant of the city. Argenta%26apos;s (2004) plagiocephaly assessment tool was used to identify the presence or absence of plagiocephaly. %26lt;br%26gt;RESULTS: Of the 440 infants assessed, 205 were observed to have some form of plagiocephaly. The incidence of plagiocephaly in infants at 7 to 12 weeks of age was estimated to be 46.6%. Of all infants with plagiocephaly, 63.2% were affected on the right side and 78.3% had a mild form. %26lt;br%26gt;CONCLUSIONS: To our knowledge, this is the first population-based study to investigate the incidence of positional plagiocephaly using 4 community-based data collection sites. Future studies are required to corroborate the findings of our study. Research is required to assess the incidence of plagiocephaly using Argenta%26apos;s plagiocephaly assessment tool across more CHCs and to assess prevalence at different infant age groups. The utility of using Argenta%26apos;s plagiocephaly assessment tool by public health nurses and/or family physicians needs to be established.
