Description of intervention(s) / exposure
Multi-nutrient formula
Participants will be randomly assigned to receive either a multi-nutrient formula or an active control for twelve weeks. After twelve weeks, all participants will enter into an open-label phase where they can choose to take the multi-nutrient formula until the birth of their child. Both the multi-nutrient formula and the active control are in capsule form and are to be taken orally at a dose of 12 capsules per day; four capsules taken three times per day with food and water. The multi-nutrient formula and active control adhere to the New Zealand Ministry of Health recommendation for the daily intake of iodine for pregnant and lactating women. The multi-nutrient intervention is a blend of vitamins, minerals, antioxidants and amino acids. The formula, Daily Essential Nutrients, is being manufactured and donated by Hardy Nutritionals (Registered Trademark), Canada and consists of the following ingredients. The following doses are for 12 capsules (full dose per day): Vitamin A (as retinyl palmitate), 5,760 IU; Vitamin C (as ascorbic acid), 600 mg; Vitamin D (as cholecalciferol), 3,000 IU; Vitamin E (as d-alpha tocopheryl succinate), 360 IU; Vitamin K (75% as phylloquinone; 25% as menaquinone-7), 120 mcg; Thiamin (as thiamin mononitrate), 60 mg; Riboflavin, 18 mg; Niacin (as niacinamide), 90 mg; Vitamin B6 (as pyridoxine hydrochloride), 69.9 mg; Folate (as L-methylfolate calcium), 801 mcg; Vitamin B12 (as methylcobalamin), 900 mcg; Biotin, 1080 mcg; Pantothenic acid (as d-calcium pantothenate), 30 mg; Calcium (as chelate), 1,320 mg; Iron (as chelate), 13.8 mg; Phosphorus (as chelate), 840 mg; Iodine (as chelate), 204 mcg; Magnesium (as chelate), 600 mg; Zinc (as chelate), 48 mg; Selenium (as chelate), 204 mcg; Copper (as chelate), 7.2 mg; Manganese (as chelate), 9.6 mg; Chromium (as chelate), 624 mcg; Molybdenum (as chelate), 144 mcg; Potassium (as chelate), 240 mg. Proprietary blend: Choline bitartrate, Alpha-lipoic acid, Mineral wax, Inositol, Acetyl-L-carnitine, Grape seed extract, Ginkgo biloba leaf extract, L-methionine, N-acetyl-L-cysteine, Boron, Vanadium, Lithium orotate, Nickel. Other ingredients: Vegetarian capsule (hypromellose), microcrystalline cellulose, magnesium stearate, silicon dioxide, titanium dioxide.
Adherence to the intervention will be assessed fortnightly throughout the study period. Participants are required to report the number of capsules missed over a two week period and return any unused capsules to the study investigators every fourth week.

Comparator / control treatment
Active placebo formula
The active placebo formula is manufactured and donated by Hardy Nutritionals (Registered Trademark), Canada and consists of the following ingredients taken orally at a dose of 12 capsules per day; four capsules taken three times per day with food and water. The following doses are for 12 capsules: Riboflavin, 1.2g; Potassium iodide, 150 mcg; Silicon dioxide, 30mg; Magnesium stearate, 60mg; Microcrystalline cellulose, 6g.

Riboflavin is known to change the colour of urine and has been added to the active control so that both the intervention and active control group experience the same change in urine colour. Adding riboflavin to the active control formula will ensure the blind is maintained.

Reference group
A reference group of pregnant women will be recruited in order to further interpret the impact of the intervention. The reference group will not receive the intervention.
Control group
Active

Statistical methods / analysis
In 2014, there were 57,242 live births in New Zealand, 6,575 of which were in Christchurch (Statistics New Zealand, 2015). Assuming at least 12% meet criteria for PND and accounting for twin births of 1 in every 100 pregnancies, approximately 781 women per year would be eligible for the proposed study in Christchurch alone.

Based on previous research, to detect a medium effect (Cohens d = 0.6) on the EPDS between groups at a two tailed significance level of 0.05 and power of 0.8 the minimum sample size would be 90 (45 in each group). Assuming a 30% attrition rate (based on the mean attrition rate from previous nutrient RCTs using perinatal women) the adjusted number per treatment condition would be approximately 60. Therefore, the total target sample size for this study is 120 (60 in the micronutrient group and 60 in the placebo group). In order to further interpret the impact of the intervention, we will be following a non-randomized control group of pregnant women who are either not eligible to participate in the intervention trial or choose not to participate. The total sample size of this group is unknown.

All statistical analyses will be carried out using the Statistical Package for Social Science (SPSS). Demographic characteristics will be compared across the treatment groups using independent samples t-tests in order to test for potential failures of randomization. All data will be analyzed on an intention-to-treat basis using the last observation carried forward method.

For the primary outcomes (EPDS and CGI-I scores), the repeated measures of the outcome variables will be modelled using generalized linear mixed effects regression models. These models will permit the testing of differences between the micronutrient group and the placebo group over the course of the trial. In the case of the EPDS, baseline scores will be used as a covariate factor, as well as measures of demographic characteristics, behaviour and social support, and measures of inflammatory biomarkers.

For secondary outcomes (MADRS. DASS, biomarkers), linear mixed effects models will also be used, and again will be supplemented by as measures of demographic characteristics, behaviour and social support, and measures of inflammatory biomarkers.

The pooled mean scores (and standard deviations) over the course of the trial on each of the primary outcomes will be used to compute estimates of effect size (Cohen’s d).
