Background: Meeting 24-hour movement behaviors (physical activity, sleep, and sedentary time) are linked to positive health benefits in young children. However, limited research is available of the proportions of preschool-aged children meeting these behavior guidelines and if the proportions vary based upon sex on a regional level. 

Purpose: To determine the proportion of preschoolers that meet 24-hour movement behavior guidelines for children under five in Western Massachusetts and assess if proportions vary based upon sex differences. 

Methods: We used a cross-sectional study of preschool aged children (3-5 yrs old) composed of two assessment phases. The first phase included a collection of child anthropometric measures. The second phase included monitoring the child’s 24-hour movement behaviors levels for one week via a wrist-worn GENEActiv activity monitor. This phase included a caregiver questionnaire and a daily log of their child’s movement behaviors. 

Planned Analysis: First, the proportion of the sample meeting the full 24-hour movement behavior guidelines, as well as each individual behavior recommendation will be calculated. Second a binary logistic regression will be used to examine whether the sex is associated with meeting the guidelines.

Implications: These findings will identify the proportion of young children from Western Massachusetts in our sample who are meeting the WHO guidelines, and this varies by sex. We anticipate that our findings will provide preliminary information to help identify needs and tailor future movement and sleep promotional approaches in this region.
