This study shows the role of excess body weight, especially if the onset is during early adulthood, and elevated height in the risk of differentiated thyroid cancer in populations born in French Polynesia.

French Polynesia is a mild iodine deficiency area in which a higher consumption of food from the sea and a higher dietary iodine intake are significantly associated with a decreased risk of thyroid cancer. The quantification of this reduction requires specific investigation of iodine intake in traditional Polynesian food.
