简要总结
To pilot a stand-alone mobile phone intervention with Latino caregivers of 2- to 5-year olds, using a prospective control group design, to assess feasibility and preliminary effect sizes on children's BMI changes (primary outcome) and dietary and physical activity changes (secondary outcomes) at 6 months post-baseline, in preparation for a larger randomized trial to evaluate the intervention's efficacy.
详细描述
The investigators will pilot an mHealth intervention using a prospective control group design with 66 caregiver-child dyads (33 intervention and 33 comparison) recruited from two community based agencies in East Los Angeles. Fidelity and feasibility will be assessed. Pre- and post- intervention data (child dietary, physical activity, and media viewing behaviors and BMI z-scores) will be collected to estimate preliminary effect sizes and standard deviations. The mHealth intervention has been informed by a previous feasibility study and focus groups with Latino caregivers of 2- to 5-year old children. This mHealth childhood obesity intervention specifically targets Latino mothers, fathers, and grandmothers of 2- to 5-year olds. The intervention focuses on parenting skills, dietary, physical activity, and media-viewing behaviors consistent with American Academy of Pediatrics guidelines.

盲法说明
A research assistant not working on any other aspect of the study, and therefore having no knowledge of whether participants are in the control or intervention group, will measure child and caregiver height and weight. A 2nd research assistant, who is not blinded to participants, will be responsible for making appointments with participants for height and weight measures.
