Intervention/exposure

Study type

Interventional

Description of intervention(s) / exposure

1. High - DHA feeding practice: mothers diet supplemented with tuna oil capsules 6x 500mg DHA rich tuna oil capsules per day to increase DHA in breast milk. If formula is required a high DHA commercial preterm formula is used.
The intervention will commence within 5 days of the preterm infant commencing enteral feeds and continue until the expected term date (40 weeks post menstrual age).
Follow up will occur at 4, 12 and 18 months corrected age.

Intervention code [1]

Other interventions

Comparator / control treatment

2. Standard infant feeding practice. Mothers take 6x500mg placebo soy oil capsules or standard preterm infant formula.

Control group

Placebo

Summary

Brief summary

Docosahexaenoic Acid (DHA) is a long chain omega 3 polyunsaturated fatty acid which is important for growth and development. DHA also plays an essential role in the development of the central nervous system and retinal function in infants. Preterm infants are denied the large amount of DHA which is normally delivered via the placenta in the last trimester of pregnancy. The DINO trial is a multi-centre, randomized controlled trial to determine whether increasing the level of DHA in breast milk will improve the developmental outcome of preterm infants who are born less than 32 weeks gestation. Study participants, clinicians and trial personnel will be blinded to treatment allocation.
