BCNN Studies

Currently Enrolling:

LiBra: This study examines the relationship among diet, physical health, and cognitive performance in children ages 8 to 13 years.  Participation involves 2 visits to Freer Hall and possibly 3 visits to Beckman Institute.  Measures will include health behaviors such as diet and physical activity, weight status, brain imaging, and a blood draw.  Participants will receive up to $300.  IRB #19811

SHELL Study: This study examines the relationships among dietary intake, retinal health, and cognition in children ages 7-12 years. Participation involves 1 to 2 in-person visits to our laboratory (2.5hours/day) and 1 to 2 online sessions (1 hour each). During these visits, children will be asked to complete eye tests and perform computer-based cognitive tasks. Participants may also qualify to receive daily snacks for 4 weeks. Families will earn between $100 to $300 for their participation. IRB #18305

SNACKing Study: This study investigates the relationship among diet, gut health, and metabolic health in adults between the ages of 30-60 years.  Participation consists of a 12-week period where participants consume a pre-packaged snack twice per day.  Participants are asked to visit the lab for 3 sessions to complete a body composition scan, liver ultrasounds, and blood draws and be asked to complete questionnaires remotely.  Six stool samples will also be collected.  Participants will receive $50 after the first two visits and $250 upon completion. IRB #20154

LUMES: Lutein and Multiple Sclerosis Evaluation Study. LUMES is examining the relationship between macular carotenoids, retinal health, and cognition in people with Multiple Sclerosis in adults ages 18-64 years.  IRB #20012


BAT Kids: Behavioral Associations with Thinking in Kids is a study for children ages 4-5 years that is investigating the relationship between early life nutrition and thinking ability.

CATS:  The aim of this study is to determine the relationship among the various nutrition status assessment techniques in adults. Participation in this study involves up to 1 session about 3.5 hours long where will measure your height, weight, waist circumference and ask you to complete surveys to understand your diet and physical activity habits. We will also conduct cognitive tests and conduct simple eye tests and a skin test to understand your habitual diet.  Participants receive $40 upon completion.

EPOCH: Evidence-based dietary strategies provide behavioral means of mitigating the effects of obesity on physical and cognitive function in adults ages 25-45 years. The EPOCH study aims to investigate effects of a fermented dairy beverage consumption and a lactose-free dairy beverage with added dietary prebiotic fiber on changes in behavioral and biological measures of cognition and stress among obese adults.

Gardening and Family Health Study: This study aims to understand the relationship between gardening and individual and family health.  Two adults between the ages of 18-45 and one child between the ages of 5-17.

Gut-Brain: A cross-sectional study in adults ages 25-44 years aimed at examining the relationship between lifestyle behaviors, gut function, metabolism, and thinking ability.

HAPPIMOMs: Health Assessments Pre and Postpartum Involving Macular pigments, Obesity/Overweight, and Microbiome Study. HAPPIMOMs examines the relationship among aspects of nutrition, gut health, and weight changes during and after pregnancy.  Women in any stage of pregnancy or those who have recently given birth (<12 weeks prior) can participate. Sessions last about 1.5 hours each and include surveys and several non-invasive measurements.  Participants will receive up to $150.

PATH: A 12-week dietary intervention in adults ages 25-45 years aimed at examining the relationships between dietary intake, gut function, metabolism, and thinking ability.

RETLU: This study retrospectively investigates the effects of early life nutrition on brain structure, function, and cognition among current and previous child participants ages 7-12 years.

WITIKids: Water Intervention for Thinking in Kids ages 9-10 years. This study aims to assess the effects of fluid intake reduction on markers of hydration status and cognitive function.
