Problems most concerning to parents of children with ADHD and emotional dysregulation in a randomized controlled trial of multinutrients: MADDY secondary analysis.

Objective: With dual focus on structured, objective quantification of parent observations of child's behavior and identifying behaviors most amenable to change, this report examines Parent Target Problems (PTP) as a secondary outcome in a randomized clinical trial (RCT) of children with attention-deficit/ hyperactivity disorder (ADHD) in which one primary outcome, Clinical Global Impression-Improvement, showed a significant advantage of multinutrients over placebo and the other, Likert-type parent ratings, showed significant improvement in both groups, without significant difference between them.

Method: In a multisite 8-week RCT of broad-spectrum micronutrients ("multinutrients"), parents of children ages 6-12 (N = 126, 73% male, 88% white) with ADHD and emotional dysregulation nominated their child's most concerning problem(s) at baseline and quantified them by frequency, duration, impairment, and consequences. At subsequent visits, parents re-quantified the problem(s).

Evaluating mineral biomarkers as mediators and moderators of behavioural improvements in a randomised controlled trial of multinutrients for children with attention-deficit/hyperactivity disorder.

Essential minerals are cofactors for synthesis of neurotransmitters supporting cognition and mood. An 8-week fully-blind randomised controlled trial of multinutrients for attention-deficit/hyperactivity disorder (ADHD) demonstrated three times as many children (age 6-12) had significantly improved behaviour ('treatment responders') on multinutrients (54 %) compared with placebo (18 %). The aim of this secondary study was to evaluate changes in fasted plasma and urinary mineral concentrations following the intervention and their role as mediators and moderators of treatment response.

Dr. Johnstone et al. Reply to Dr. Hamilton.

We thank Dr. Hamilton for his interest in our research and for provoking a more nuanced and detailed approach to analyzing the relationship among treatment assignment, treatment response, and correct treatment guessing in randomized controlled trials; in this case, the Micronutrients for ADHD in Youth (MADDY) study..

Dr. Johnstone et al. Reply to Dr. Elmrayed.

We thank Dr. Elmrayed and colleagues for highlighting clinical cautions in using broad-spectrum micronutrients to treat attention-deficit/hyperactivity disorder (ADHD) in children, in particular manganese (Mn) levels. We appreciate the opportunity to provide additional information and rationale for the vitamin and mineral doses contained in the studied formula.

Food Related Challenges and Mental Health Among U.S. African Migrants: A Narrative Review.

The United States' (US) African immigrant (AI) population is growing, yet they are underrepresented in health and nutrition research. This population experiences difficulties finding culturally appropriate foods and navigating the US food environment (FE), is highly food insecure (FI), and vulnerable to mental disorders. This review examined the current evidence for AIs' food and mental health outcomes and connections; and identified gaps in the literature and future research opportunities.
