Plain English Summary
Background and study aims
Breast milk is the best milk to give to preterm babies when they are first ready to receive milk, and breast feeding may also be the best milk to give them when they are ready to go home. However, between now and when they are ready for home, we know that your baby will need some extra energy, protein and vitamins to help him/her grow adequately. To give your baby these extra nutrients, our standard practice would be to give your baby a combination of breast milk and a special formula designed for preterm babies so they would usually get half and half. An alternative would be to give your baby all his/her milk as breast milk but add some extra nutrients using a fortifier. This comes as a powder which we simply add to the breast milk before giving it. We do not know which is the best option for babies like yours, and this study is trying to help find out why. Although it might seem more logical to add a fortifier, there are concerns that this may disturb the delicate blend of breast milk. On the other hand, supplementing with a preterm formula milk may mean we dont give as much breast milk early on as you would like.
Who can participate?
Preterm babies (less than 35 weeks gestation) receiving maternal breast milk.
What does the study involve?
If you are happy to take part we will open a sealed envelope which will tell us whether to give your baby breast milk plus formula or to use a fortifier. The envelopes have been prepared in a random order by a computer so we do not know which one your baby will get until we open it. There is a 50-50 chance that your baby will receive fortifier or formula supplementation. Your baby will then only be fed by that option until they are ready to go home. During the study we will measure your babys weight and length every week. Your baby will only have blood tests if these are decided to be necessary by the doctors looking after your baby i.e. this study does not involve extra blood tests or investigations. Most preterm babies like your will need their bloods checking about once a week, or more often if they are not well. If you change from providing breast milk, or there is not enough breast milk is available we will use the most appropriate formula available to make up the shortfall.
When your baby is ready to go home we will ask you a few short questions on how you think the study went. We will keep in contact with you by phone after discharge to see how long you continue to breast feed (if you have decided to continue) and when you decide to wean your baby (start solids). If your baby needs to see a doctor after discharge this would take place in the normal way. We will make sure you know this before you go home.
What are the possible benefits and risks of participating?
We hope that both ways of feeding your baby will be successful but we do not know for sure which is best. We hope that the information we get from this study will help us look after babies like yours better in the future. As far as we are aware there are no significant risks associated with the study. The study conforms to internationally recommended guidelines. Both formula and fortifier are already widely used in other units. Because both these methods of feeding are already being widely used we do not believe that taking part in this study will harm your baby.

Study information
Scientific title
SUPFOR breast milk study: a randomised controlled trial in preterm infants receiving expressed breast milk comparing the use of breast milk fortification versus SUPplementation using a preterm FORmula
Acronym
SUPFOR
Study hypothesis
The use of a Breast Milk Fortifier (BMF) compared with supplementation using a preterm formula will result in improved growth without an increased incidence of biochemical abnormalities or adverse effect. The use of a BMF will also result in greater parental satisfaction and improved duration of breast feeding.

Condition
Nutrition in preterm infants
Intervention
Groups are minimised on:
1. Growth retarded less than 10 cm
2. Multiple pregnancy
3. Gestation greater than 31 weeks
Interventions:
Formula supplement (control): 50% of total enteral feeds are provided by a low birth weight formula. We are using Nutriprem (Cow & Gate, Nutricia, Trowbridge, UK) and the intervention continues until initial hospital discharge. Follow up finishes then.
Fortifier arm (intervention): fortifier is added to all enteral breast milk feeds until hospital discharge. Follow up finishes then.

Primary outcome measures
1. Weight gain (g/day) during initial hospital stay, measured three times a week
2. Length gain (mm/week) and head growth (mm/week) during initial hospital stay, measured once a week
3. Duration and amount of breast milk provided, measured daily
Secondary outcome measures
1. Maternal satisfaction, measured weekly and then at discharge
2. Incidence of abnormal biochemistry, measured when samples are taken - usually once a week
