Background

Families face a range of barriers in supporting their children’s active play in nature including family circumstances, environmental constraints, and behavioral factors. Evidence-based strategies to address these barriers are needed. We aimed to develop and pilot test a primary care-based family-centered behavioral intervention to promote active outdoor play in 4–10 year-old children.

Methods

Project Nature, a provider-delivered intervention that provides informational resources and an age-appropriate toy for nature play, was initially developed for children ages 0–3. With stakeholder input, we adapted existing materials for 4–10 year-olds and conducted usability testing at an urban clinic serving families from diverse backgrounds. Subsequently, we conducted a mix-methods pilot study to evaluate intervention feasibility and acceptability. Parents of 4–10 year-olds completed pre- and post-surveys (n = 22), and a purposive subset (n = 10) completed qualitative interviews. Post-intervention, pediatric providers (n = 4) were interviewed about their implementation experiences.

Results

The majority (82%) of parents liked the information provided and the remaining (18%) were neutral. Qualitatively, parents reported that: the toy provided a tangible element to help children and parents be active, they did not use the website, and they wished the intervention emphasized strategies for physical activity during cold and wet seasons. Providers felt the materials facilitated discussion about behavior change with families. There were no statistically significant changes in PA and outdoor time pre- and post-intervention.

Conclusions

Project Nature was welcomed by providers and families and may be a practical intervention to promote outdoor active play during well-child visits. Providing an age-appropriate nature toy seemed to be a critical component of the intervention, and may be worth the additional cost, time and storage space required by clinics. Building from these results, Project Nature should be revised to better support active outdoor play during suboptimal weather and evaluated to test its efficacy in a fully-powered trial.

Visual Acuity Assessment and Vision Screening Using a Novel Smartphone Application

OBJECTIVES:

To evaluate a smartphone-based application's (Peek Acuity) ability to assess visual acuity and screen for ocular conditions in children, we compared visual acuity assessment between Peek Acuity and the pediatric ophthalmology examination and evaluated Peek Acuity's ability to identify children with referable ocular conditions.

STUDY DESIGN:

We prospectively recruited 111 children age 3-17 years, presenting to a pediatric ophthalmology clinic, who could follow instructions. Monocular visual acuity assessments by Peek Acuity and standard clinical methods were performed in randomized order. We compared visual acuity assessments between methods using intraclass correlation coefficient (ICC) and evaluated Peek Acuity's ability to identify children with referable ocular conditions.

RESULTS:

ICC comparing visual acuity assessed between methods was 0.88 (95% CI 0.83-0.92) for first and 0.85 (95% CI 0.78-0.89) for second eyes examined. ICC among 3 to 5-year-olds (preschool-age children) was 0.88 (95% CI 0.77-0.94) for first and 0.45 (95% CI 0.13-0.68) for second eyes examined. Peek Acuity had a sensitivity of 83%-86% for decreased vision and 69%-83% for referable ocular disease. Sensitivity was highest among 3 to 5-year-olds with decreased vision, 93%-100%.

CONCLUSIONS:

Overall, Peek Acuity visual acuity assessment correlated well with visual acuity assessed by standard clinical methods, though preschool-age children appeared more susceptible to examination fatigue. Peek Acuity performed adequately as a screening tool and had the greatest sensitivity among those with decreased vision and preschool-age children.
