Study summary

This is a study evaluating the relationship between prenatal nutrition and neural development in infants born to mothers with Attention Deficit Hyperactivity Disorder (ADHD). We are hypothesizing that women randomized to a whole food, nutrient-dense diet during their 3rd trimester of pregnancy will have infants with more advanced neural development as compared to infants born to mothers receiving standard-of-care treatment.

Read the detailed description

Pregnant women with ADHD will be recruited from the patient population at Oregon Health \& Science University (OHSU). They will be recruited during their 1st or 2nd trimester. After consent, baseline measures will be collected including height, weight, body composition measurements using calipers, 24-hour dietary recalls, and blood and urine samples. Women will also complete questionnaires regarding ADHD symptoms, stress, depression, and lifestyle. Women will be given a one-week food diary to fill out at home, which will be mailed in upon completion. Upon receipt of the food diary, women will be randomized into either a nutrition intervention group or a standard-of-care group. Women who are randomized to the intervention group will receive individual nutritional counseling every 2 weeks during their 3rd trimester of pregnancy. Before delivery, the baseline measures described above will again be collected. At delivery, placenta and cord blood samples will be taken. After birth, the infant will undergo an MRI between 2 and 5 weeks of age. The scan is completed while the baby sleeps, and special ear protection is worn to limit sleep disruption from the noise of the MRI. When the infant is 3 months old, mothers will complete questionnaires about infant feeding, sleep and behavior.

Study arms

  • Experimental
    Dietary Intervention

    A whole food, nutrient-dense dietary intervention which restricts processed foods high in food additives and optimizes micronutrient intake.

    Behavioral: Whole Food, Nutrient-Dense Dietary Intervention

  • Placebo comparator
    Standard-of Care Group

    This group will receive normal standard-of-care for pregnancy.

    Behavioral: Standard of Care

Interventions

  • BehavioralWhole Food, Nutrient-Dense Dietary Intervention

    The dietary intervention will be a whole food, nutrient-dense diet which restricts processed foods high in food additives while optimizing micronutrient intake.

  • BehavioralStandard of Care

    Normal standard-of-care for pregnancy.

What researchers measure

Primary outcomes

  1. Functional neuroconnectivity of neonate assessed by MRI

    MRI will be used to examine brain morphology and functional connectivity in the neonates.

    Time frame: 2-5 weeks after birth

Secondary outcomes

  1. Blood nutrient concentrations

    Maternal blood nutrient concentrations will be examined to assess whether or not the intervention group had higher nutrient levels in the 3rd trimester than the standard-of-care group.

    Time frame: Assessed at consent and end of 3rd trimester
