	Barker collected low birth weight data in the early 1900’s in the south east of England which he then compared with these same babies later health outcomes and it was this statistical analysis that lead to the theory that postnatal health is linked with prenatal development. Therefore the theory was originally called the “Barker Hypothesis” but recently the theory has been renamed as the “fetal origins hypothesis” or “programming hypothesis”		Barker collected low birth weight data in the early 1900’s in the south east of England which he then compared with these same babies later health outcomes and it was this statistical analysis that lead to the theory that postnatal health is linked with prenatal development.

	The main hormone that both initiates and maintains labour during birth is Oxytocin, which is a 8aa peptide hormone which is secreted by the maternal posterior pituitary. Another group of hormone that are involved in the initiation and maintenance of labour are the Prostaglandins such as PGF2 Alpha and these are synthesised by the placenta.

	The affects of iodine deficiency or in other words low dietary iodine affect non-endocrine system development by causing problems at and before birth such as miscarriage and still birth and mental retardation. Children that have an iodine deficiency can have a stunted growth, low body weight, low body temperature, poor muscle tone and are usually lethargic. They may also not be able of normal speech, hearing and movement due to this iodine deficiency.
