This position will support a randomized controlled trial of a primary care-based intervention to prevent obesity among low-income Latino infants and toddlers. Roles may include trial recruitment, data collection via surveys and medical records review, and conducting 24-hour dietary recalls with parents of infants and toddlers at well child visits and over the phone. The study will take place at two sites: the San Francisco General Hospital Children’s Health Center and the Santa Clara Valley Medical Center outpatient clinic in Sunnyvale, CA and will enroll low-income Latino families who are primarily Spanish speaking. Candidates should expect to work in person at the San Francisco site approximately 2.5 days week and at the Sunnyvale site on the other days. There will be a limited amount of remote work each week.
