Abstract

. The authors conducted a longtitudinal study of poor pregnant women and their infants to examine the determinants of maternal and infant lead levels. To accurately depict these determinants, one must account for secular and seasonal variations in these levels. The women's lead levels declined over the 5-y period of study by approximately 20%/y, depending on when in the course of pregnancy measurements were made. After correction for secular trend, we found a periodic effect that differed from that typically seen in children (i.e., peak occurs in summer). In this study, lead levels in these women peaked during December-March. If the effects of lead are greatest in the youngest concepts, early pregnancies that occur in the December-March period pose the largest prenatal risk., NEONATAL LEAD LEVELS are predictors of important health outcomes, including the child's cognitive and physical development.[1] Lead transfers through the placenta; therefore, the neonate's lead exposure results from the mother's [...]

Abstract

The New York State Farm Family Health and Hazard Surveillance was conducted to assess the health status and safety practices among year-round adult farmers and farm residents in New York State and included a telephone interview survey of 1,727 persons from 552 farms. To determine the extent to which self-reported hearing loss is in agreement with audiometry, a subset of 376 participants who completed a hearing loss interview and pure-tone audiometry was analyzed. Thirty-six percent of the participants had self-reported hearing loss, defined as at least some difficulty hearing in one or both ears. The prevalence of audiometric hearing impairment, defined as a threshold average greater than 25 dB hearing level, was 9% for the binaural low-frequency average (500, 1000, and 2000 Hz), 29% for the binaural mid-frequency average (1000, 2000, 3000, and 4000 Hz), and 47% for the binaural high-frequency average (3000, 4000, 6000, and 8000 Hz). Agreement between self-report and audiometry was highest for the binaural mid-frequency average (kappa statistic 55%, sensitivity 77%, and specificity 82%). Self-reported hearing loss was found to be a moderately good measure of hearing impairment. We conclude that a simple questionnaire focusing on hearing difficulty is a useful and valid tool for conducting epidemiologic studies of farmers. Whenever possible, a substudy using audiometry should be conducted. [ABSTRACT FROM AUTHOR]
