Step by Step: Investigating Children's Physical Activity and Enjoyment in Outdoor Walking with Their Parents

Background/Objectives: Although public health organizations encourage family walking, no studies have examined children's physical activity and enjoyment during outdoor parent-child walks. This study addresses those gaps by examining children's moderate-to-vigorous physical activity (MVPA) and enjoyment during outdoor walks with their parents, along with parental barriers and their relationship with parent's self-efficacy and co-activity minutes. Methods: Fifty parent-child dyads (children aged 6-12 years) completed 10 min, self-paced outdoor walks while wearing waist-worn ActiGraph monitors. Parents reported perceived barriers to walking outdoors with their child and self-efficacy for supporting their child's daily physical activity. Results: Children reported high enjoyment (mean = 5.1 on a six-point scale) and attained high physical activity intensity (71.3% of time in MVPA, 22.0% in vigorous activity, mean step count = 1200). Parents reported an average of 2.6 barriers (SD = 1.0) to walking outdoors with their child, with poor weather (70%) and lack of time (70%) reported most frequently. Each additional barrier was associated with a 1.3-point reduction in parents' self-efficacy (p = 0.007). Two barriers ('diverse interests between parent and child' and 'other parent-suggested barriers') were significantly associated with fewer co-activity minutes per week (p < 0.001). Conclusions: Our study highlights the benefits of parent-child outdoor walking for promoting MVPA and enjoyment in children. Because perceived barriers may lower parents' self-efficacy in supporting their child's physical activity, addressing these barriers may be essential for the success of family-based interventions that encourage walking together outdoors.
