Allocation: NON_RANDOMIZED
Intervention model: PARALLEL
Intervention model description: controlled, non-randomized community nutrition intervention
Primary purpose: PREVENTION

Brief summary: A community nutrition trial among a diverse low-income population that tested the effect of parent-child cooking nutrition intervention on vegetable intake among 9-12 children.

Detailed description: This study was a nonrandomized, controlled trial to determine whether a series of 6 weekly parent-child vegetable cooking skills classes and parent-led strategies informed by behavioral economics (1/week) (intervention group) improved dietary and non-dietary outcomes of a racially and ethnically diverse sample of low-income children (ages 9-12) more than a vegetable cooking skills program alone (control group).

Eligibility criteria: Inclusion Criteria:

* Participant child must be 9-12 years old
* Parent must be the main food preparer for the household
* The family must qualify for some form of public assistance
* Have a phone
* Must not have participated in a previous Cooking Matters for Families in the past 3 years
* Be able to read, speak, and understand English (or Spanish for Spanish-only courses).

Exclusion criteria:

\*No exclusions other than those that do not meet inclusion criteria

Primary outcomes:
measure: change in # of vegetable servings consumed by child measured by averaging vegetable serving data extracted from 3, 24-hr recalls.
timeFrame: change from baseline to 9 weeks post-baseline (i.e., immediate post-intervention)
measure: change in # of vegetable servings consumed by child measured by averaging vegetable serving data extracted from 3, 24-hr recalls.
