Mothers of preterm infants face higher emotional stress and a greater risk of postpartum depression compared to mothers of full-term infants. This increased stress can negatively affect both the mothers ability to care for her baby and the infants health and development. The study focuses on mothers in Idaho, where preterm births are common and vitamin D deficiency risk is heightened due to limited winter sunlight exposure, which may influence postpartum mental health. The trial is evaluating whether vitamin D supplementation during lactation improves vitamin D levels and reduces stress and depression in mothers of preterm infants. Participants are randomly assigned to receive either 2,000 IU of vitamin D or a placebo. The study includes a triple-blind design and measures outcomes at baseline, 4 weeks, and 8 weeks to assess maternal stress, depression, vitamin D status, and milk composition. During the study, mothers will have their mental health, physiological stress, self-compassion, and vitamin D levels monitored through questionnaires and laboratory tests at three time points. Researchers will also analyze the immunomodulatory components in breast milk. The total participation period lasts 8 weeks, with careful follow-up to understand the effects of vitamin D supplementation on both mother and infant health.

This research aims to explore how regular consumption of specially developed trout, which contain higher levels of omega-3 fatty acids important for brain health, could support cognitive and emotional wellbeing in children and adults. The study addresses the knowledge gap regarding consumer preferences for these fish and how nutrition education strategies might increase fish consumption to benefit brain health and contribute to sustainable aquaculture. Participants will be involved in different groups to assess sensory preferences for three trout strains, effects of repeated exposure and child-centered nutrition messages on eating behaviors, and the impact of nutrition education including meal preparation and exposure to positive messages at home. Interventions include weekly servings of trout, nutrition phrases, puzzle games, and Eat Smart Idahos standard educational classes, with variations across experimental and control groups. Throughout the study, participants will provide feedback on trout liking and intake, and their cognitive and emotional wellbeing will be evaluated at baseline and after 12 weeks. The research includes consumer panels, childcare settings, and home-based interventions, with data collected on changes in liking, intake, cognition scores, and emotion scores. The total participation involves repeated assessments and exposure over up to 12 weeks to monitor brain health and eating behavior changes.
