What is the PINK trial?PINK

The PINK trial is a study funded by the National Health and Medical Research Council of Australia.The PINK trial will determine whether increasing the amount of iodine in the diet during pregnancy will improve child development and maternal health and wellbeing.

What is Iodine?

Iodine is a nutrient and like calcium and iron, is found in the foods we eat. Iodine is needed by our bodies to make hormones for normal growth and plays a role in the way the brain works and develops. Getting enough iodine in pregnancy is important because the baby's brain is growing quickly and it relies on adequate iodine supply from the mother, which is influenced by the amount of iodine in the mother's diet. Recently it has been reported that the level of iodine in the diets of Australians has fallen. The Australian and New Zealand governments have introduced mandatory iodine fortification of bread. The PINK trial will determine whether pregnant women need extra iodine over and above the fortification.

What does the PINK involve?

Women will be randomly assigned (like tossing a coin) to one of two groups. One group will be asked to take tablets containing iodine and the other group will be asked to take tablets with no iodine. Women will be asked to take their tablets daily until their baby is born.

Women will be asked to complete short questionnaires about mood, well-being and diet, to provide a blood sample and urine samples to assess iodine levels.

The children will be asked to attend a developmental assessment when they are 24 months old. The assessment will take approximately one hour and involves your baby walking, moving, standing as well as playing with puzzles and other toys.

Who can participate in PINK?

Pregnant women who are less than 20 weeks gestation and are not taking supplements containing iodine.

Are the PINK supplements safe?

Yes. The amount of iodine in the tablets ensures that women who have a diet low in iodine will get enough iodine with the supplements. On the other hand women who have a diet high in iodine will not be getting too much iodine as the upper safety level is 7 times the dose of the iodine in the tablets.
