However, even with the above increased understanding, and availability of dietary supplements like cod liver oil, in early-mid twentieth century rickets continued to be common. This is beautifully illustrated in a publication originating from the Renwick hospital for sick infants in Sydney, Australia in Food fortification, dietary supplementation with cod liver oil, and increased use of vitamin D fortified infant formula led to a decrease in rickets over subsequent decades Again, a public health campaign of vitamin D supplementation targeting these recent immigrants predisposed to vitamin D deficiency reduced rickets presentations Figure 2.
In part, this is caused by reduced UVB exposure due to sun avoidance measures such as sunscreen and clothing, including for cultural reasons and other modern lifestyle factors. Complacency and our short memories for diseases from the past, including clear lapses in awareness of preexisting public health strategies for vitamin D supplementation to high risk populations have also contributed. These strategies are well-covered in recent global consensus guidelines for prevention and management of vitamin D deficiency rickets, with recommended treatment and prevention doses of vitamin D for nutritional rickets in children presented in Table 1 4.
Table 1. Suggested vitamin D cholecalciferol doses for the prevention and treatment of nutritional rickets in children 4. In conclusion, rickets is not just a modern disease. However, we can learn from the past, and an awareness of successful vitamin D supplementation campaigns over the last century is helpful. If we are to successfully prevent nutritional rickets in children, efforts to promote the existing clear guidelines on prevention are needed 4.
Please read the global consensus recommendations 4 to help in the worldwide effort to eradicate this rare but fully preventable disorder.

Arch Dis Child. Glisson F, Bate G. De rachitide, typis T. Because of growing concerns, the Centers for Disease Control will be putting out a bulletin on rickets this fall, a spokesman says. As late as the s, rickets was a common childhood ailment, killing thousands of children annually until doctors learned that that vitamin D in milk and sunlight could largely prevent it.
Today, fortified milk and prepared baby formula both contain vitamin D, largely eliminating the problem. But because breast milk contains much lower levels of vitamin D, babies exclusively fed on it may be at risk, especially if they have darker skin that blocks out sunlight; live in northern climates and receive less light or have moms with vitamin D deficiencies themselves.
The number of African-American women who are breast-feeding has been on the rise in the past decade, from about 5 to 22 percent, the Pediatrics study reports. Doctors Fail to Warn Besides the increase in breast-feeding contributing to this rise in rickets, pediatricians also may not be telling mothers to supplement the breast milk with vitamin D.
