Impact of Whole Versus Low-fat Milk on Child Health

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effects of whole cow's milk compared to 1% low-fat milk on child obesity and health outcomes in toddlers aged 2 to 3 years. It aims to determine how different milk fat types influence adiposity, measured by waist-to-height ratio and other metrics. The study will recruit 625 parents and randomly assign their toddlers to either milk group for one year, with a focus on understanding the implications of milk fat on early childhood growth and development.

Why it matters

Who can join: the full rules

Inclusion Criteria:

Parents of children: 1) willing to be randomized to provide either only whole or 1% milk to their child for 1 year, 2) access to a smart phone and a tablet, laptop or computer with internet and email at home, 3) ability to speak and read English or Spanish for the purposes of receiving study communications and completing surveys and dietary assessments (to avoid needing to translate all study materials and have research staff fluent in other languages due to budget limits), 4) not planning to move outside of the San Francisco Bay Area or discontinue being child's primary caregiver for the next year (e.g., foster care, parent separation).

Exclusion Criteria:

Children: 1) \<23 months or \>48 months old at recruitment; 2) condition or medication that affects growth or daily feeding, or cardiometabolic health such as hypopituitarism, growth hormone deficiency, inborn error of metabolism, syndromic obesity, familial hypercholesterolemia, 3) weight-for-length or height below the 2nd percentile, 4) lactose intolerance, milk allergy or other dietary restrictions (e.g., vegan) that impact ability to consume dairy or otherwise limit dietary intake, 5) resides in more than one household (e.g., shared care by separated parents), and 6) not covered by public or private medical insurance (may reduce well-child doctor visits). If two eligible children are in a household, one will be randomly selected to participate.
