Summary of "Examining Pica in NYC Pregnant Women with Elevated Blood Lead Levels."

We sought to describe the impact of pica, the craving for and intentional ingestion of substances not defined as food, as a risk factor for lead poisoning in New York City (NYC) pregnant women. In order to describe pregnant women with elevated blood lead levels (BLLs) who report pica, NYC health department data from 491 cases of lead-poisoned pregnant women from January 2001 to June 2009 were reviewed. Descriptive frequencies were obtained for women reporting pica. Data were compared between women reporting and not reporting pica. In NYC, of the 43 (9%) lead-poisoned pregnant women reporting pica, 42 (97.7%) were immigrants and 28 (64.6%) had consumed soil. Compared to lead-poisoned pregnant women not reporting pica, women reporting pica had higher peak BLLs (29.5 vs. 23.8 μg/dL, P = 0.0001), were more likely to have had a BLL ≥ 45 μg/dL (OR = 3.3, 95% CI, 1.25, 8.68) and receive chelation (OR = 10.88, 95% CI, 1.49, 79.25), more likely to have emigrated from Mexico (OR = 3.05, 95% CI, 1.38-6.72), and less likely to have completed high school (OR = indeterminate; 0 vs. 34%; P = 0.003). Among NYC lead-poisoned pregnant women, pica was associated with higher peak BLLs. Providers in NYC, and possibly other urban settings, should be vigilant and question pregnant women, especially immigrants, about pica and strongly consider testing this at-risk population for lead poisoning.

Medical and Biotech [MESH] Definitions

A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.

A syndrome of HEMOLYSIS, elevated liver ENZYMES, and low blood platelets count (THROMBOCYTOPENIA). HELLP syndrome is observed in pregnant women with PRE-ECLAMPSIA or ECLAMPSIA who also exhibit LIVER damage and abnormalities in BLOOD COAGULATION.

Human females who are pregnant, as cultural, psychological, or sociological entities.

Neurologic disorders occurring in children following lead exposure. The most frequent manifestation of childhood lead toxicity is an encephalopathy associated with chronic ingestion of lead that usually presents between the ages of 1 and 3 years. Clinical manifestations include behavioral changes followed by lethargy; CONVULSIONS; HALLUCINATIONS; DELIRIUM; ATAXIA; and vomiting. Elevated intracranial pressure (HYPERTENSION, INTRACRANIAL) and CEREBRAL EDEMA may occur. (From Adams et al., Principles of Neurology, 6th ed, p1210-2)

A pregnane found in the urine of pregnant women and sows. It has anesthetic, hypnotic, and sedative properties.
