Dr. Sacheck's recent research includes several school- and community-based intervention studies focused on diverse lower-income children and youth. Primary outcomes of these studies have included improving physical activity and dietary patterns with the ultimate goal of improving health outcomes including obesity prevention, cardiometabolic risk, cognitive health, and well-being.  

Ongoing Research Studies:

SPLASH Study (Supporting Physical Literacy at School and at Home, 2019 - present) NIH NCI R21/R33CA226829-01

The overall objective of the SPLASH Study is to increase children’s physical activity through a multilevel, comprehensive physical literacy-focused program that will reach children both at school and at home.  Primary outcomes will include changes in physical literacy and physical activity relative to engagement in school- and home-based programming.

COACHES Study  (Creating Opportunities for Adolescents through Coaching, Healthy Eating, and Sports) (2019 - present) Department of Health and Human Services CPIMP191186

This initiative is utliziing coaches trained in sports-based youth development and trauma-informed coaching strategies to improve the physical activity, physical fitness, nutritional behaviors, and social and emotional learning (SEL) of 6th and 7th grade students from urban schools who are overweight and/or at risk for obesity. 

Completed Trials:

The FLEX Study (Fueling Learning through Exercise; 2014-2019) NIH - R01HD080180-01A1

The FLEX Study was a cluster-randomized controlled trial conducted in 18 diverse public elementary schools. The overall objective was to examine the impact of two low-cost and easy to implement school-based activity programs (100 Mile Club and CHALK/Just Move) on school-time and daily physical activity among schoolchildren over two school years.  Secondary outcomes included the impact of physical activity programming on cognitive outcomes and academic achievement. 

The Daily D Health Study  (2011-2015) NIH - R01HL106160

The Daily D Health Study (Daily D) was a randomized double-blind clinical trial examining the impact of three supplemental doses of vitamin D on changes in serum 25(OH)D and cardiometabolic risk factors over six months among diverse urban children and youth. Children were randomized to 600, 1000, or 2000 IU/day of vitamin D3 for six months, and subsequently followed for another 6 months post-supplementation.
