Lifetime low-level exposure to environmental lead and children's emotional and behavioral development at ages 11-13 years: the Port Pirie Cohort Study

Article Abstract:

Lead exposure may impact later behavioral and emotional problems of children. Researchers studied the emotional problems of 322 children aged 11 to 13 relative to environmental lead exposure in an Australian lead smelting community. Aggressive and delinquent behavior in boys and withdrawn/anxious behavior in girls rose as the amount of lead exposure increased. In contrast to boys, girls had problems in both externalizing and internalizing behaviors.

Comparison of the entropy technique with two other techniques for detecting disease clustering using data from children with high blood lead levels

Article Abstract:

The entropy method and the nearest neighbor technique may be able to detect a wide variety of cluster types. Moran's IPOP technique may be generally less effective than the other two methods of clustering. Researchers contrasted the three methods for detecting disease clustering in children with high blood levels of lead in south-central Los Angeles, CA.

Prisoners of the proximate: loosening the constraints on epidemiology inan age of change

Article Abstract:

The constraints upon modern epidemiology are loosening. Epidemiologists must broaden causal models that examine disease in individuals in terms of behavior, exposure metabolic factors and genes. Epidemiologists need to recognize the effect of social-environmental influences on health and disease, especially at the advent of a new century.
