Secondary study design	Randomised controlled trial
Study setting(s)	Not specified
Study type	Prevention
Scientific title	The effects of antenatal multiple micronutrient supplementation on birth weight, gestation and infection: a double blind, randomised controlled trial conducted in Nepal
Study acronym	MIRA (Mother and Infant Research Activities) - a Nepali Non-Governmental Organisation (NGO): Janakpur Multiple Micronutrient Supplementation Study
Study objectives	Neonatal mortality is the biggest contributor to global mortality of children younger than five years, and low birth weight is a crucial underlying factor. This study is a double blind, randomised controlled trial of the effects of antenatal multiple micronutrient supplementation on birth weight, gestation and perinatal infection, conducted in Dhanusha district, Nepal. Added 15/02/2007: 1. Second and third trimester supplementation with a multiple micronutrient regime will increase birth weight 2. Second and third trimester supplementation with a multiple micronutrient regime will prolong gestation 3. Second and third trimester supplementation with a multiple micronutrient regime will make mothers less susceptible to infection
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Low birth weight
Intervention	Intervention arm (600 participants): Daily multiple micronutrient tablet from enrolment to delivery: Vitamin A 800 mcg, Vitamin E 10 mg, Vitamin D 5 mcg, Vitamin B1 1.4 mg, Vitamin B2 1.4 mg, Niacin 18 mg, Vitamin B6 1.9 mg, Vitamin B12 2.6 mcg, Folic acid 400 mcg, Vitamin C 70 mg, Iron 30 mg, Zinc 15 mg, Copper 2 mg, Selenium 65 mcg, Iodine 150 mcg. Control arm (600 participants): Daily government-recommended supplement from enrolment to delivery: Iron 60 mg, Folic acid 400 mcg.
Intervention type	Supplement
Primary outcome measure	Added 15/02/2007: Primary outcomes (1200 participants): 1. Birth weight, length and head circumference measured within 72 hours of birth 2. Gestation at birth calculated on the basis of obstetric ultrasound biometry at enrolment
Secondary outcome measures	Added 15/02/2007: 1. Micronutritional Outcomes (200 participants): venous blood collected at 32 weeks gestation for measurement of plasma vitamins A, C, E and ferritin 2. Immunological outcomes (600 participants): 2.1. Clinical indicators of infection at every contact 2.2. Venous blood collected at 32 weeks gestation for measurement of neopterin 2.3. Breast milk collected at one month postpartum for measurement of sodium/potassium ratio
