Pica iron deficiency3/17/2023 Department of Agriculture and the National Institutes of Health. “My hope is that these studies put pica on the radar as a legitimate public health issue.” “The public health importance of pica really needs to be acknowledged,” said Young. Pica was defined as the daily compulsive eating of food or non-food items, singly or in combination, not ordinarily part of the patient's habitual diet or preferences, for more than one month, and not reasonably attributable to causes other than iron deficiency by the patient or treating physician. At the same time, “ice is not going to change someone’s iron status,” said O’Brien, leading to her hypothesis that iron deficiency may have an effect on brain chemistry that leads to these cravings. It can occur in adults who crave a specific type of texture in the mouth. When people crave ice, they consume “cups and cups and cups of it,” said Young. Pica is usually temporary and can affect pregnant people and others with iron-deficiency anemia or other nutrient deficiencies who may crave certain minerals found in dirt, or eat earthy material like clay. Texture appears to be very important to those engaged in pica and is one commonality among the types of substances consumed. Of the nearly 47 percent of adolescents who reported pica behaviors, most – 82 percent – craved ice, followed by starches, powders, soap, paper, plastic foam such as pillow stuffing or sponges, baking soda, and a few other items. The study included African-American, white and Latina pregnant teens. Pica is Prevalent and Strongly Associated with Iron Deficiency, but not Anemia, among Mexican-born. “As anemia increased, so did these behaviors, but we don’t know what happens first,” said Kimberly O’Brien, professor of nutritional sciences and the study’s senior author. Aditi Roy, Elena Fuentes-Afflick, Lia Fernald, Sera Young. In the study, pica behaviors and iron deficiency increased over the course of the pregnancies. “In this study, the strength of the association between pica and anemia is as big as any known causal factor of anemia in pregnant teens this is a very strong association,” said Sera Young, a research scientist in nutritional sciences in Cornell’s College of Human Ecology and a co-author of the study published online in the Journal of Nutrition. Low iron in pregnant teens raises the risk of premature births and babies with low birth weights, which in turn increases infant mortality rates. Pregnant teens, regardless of pica, are at higher risk for low hemoglobin, which can lead to iron deficiency and anemia. In rare cases when iron deficiency is very bad, a child may develop pica, which is a craving to eat items that are not food, such as dirt, paint chips, chalk. A desire to eat peculiar substances such as dirt or ice (a condition called pica). 28.Moreover, such teens had significantly lower iron levels as compared with teens who did not eat nonfood substances. The condition is often associated with iron deficiency with the. The mechanisms whereby iron deficiency produces pica are not known, but iron sup- plementation relieves cravings rapidly, even before correction of the anemia.
