Mobile Device Use Among Rural, Low-Income Families and the Feasibility of an App to Encourage Preschoolers' Physical Activity: Qualitative Study.

Background: As mobile devices are becoming ubiquitous, technology-based interventions provide a promising strategy to positively influence health behaviors of families with young children. However, questions remain about the feasibility and acceptability of intervention delivery via mobile apps in low-income, rural settings and among families with preschoolers.

Objective: The aims of this study were to understand the content and context of mobile device use for preschoolers; explore parent beliefs on this topic, including the acceptability of intervention delivery via mobile devices; and test a prototype of an app to encourage preschoolers' physical activity with both parents and children.

HEROs: Design of a Mixed-Methods Formative Research Phase for an Ecocultural Intervention to Promote Healthy Eating and Activity Behaviors in Rural Families With Preschoolers.

Objective: To describe the mixed-methods formative research phase in the development of the Healthy Environments Study (HEROs), a technology-based, interactive family intervention to promote healthy eating and activity behaviors for young children in the home environment.

Design: A mixed-method iterative approach, using ecocultural theory as a framework, will guide the development of both quantitative and qualitative formative research assessments.

Setting: Rural eastern Colorado.

Parent Perceptions of Mobile Device Use Among Preschool-Aged Children in Rural Head Start Centers.

Objective: To describe child use and parents' beliefs and comfort with young children's use of mobile devices in low-income, rural communities.

Methods: This was a descriptive, cross-sectional study. The survey, which consisted of 18 multiple-part questions, was distributed to families at 5 Head Start/preschool centers in Colorado.

The Bioenhancer Piperine is at Least Trimorphic.

Polymer-induced heteronucleation (PIHn), a powerful crystalline polymorph discovery method, has revealed two novel polymorphs of the low solubility bioenhancer piperine. Both of these forms exhibit enhanced solubility when compared to the commercial polymorph, thereby potentially improving the efficacy of piperine as a bioenhancer. Structural comparison of the three forms reveals that π-π interactions are only present in the two newly discovered forms.
