Placental biomarkers of PAH exposure and glutathione-S-transferase biotransformation enzymes in an obstetric population from Tijuana, Baja California, Mexico.

Environmental exposures along the US-Mexico border have the potential to adversely affect the maternal-fetal environment. The purpose of this study was to assess placental biomarkers of environmental exposures in an obstetric population at the California-Baja California border in relation to detoxifying enzymes in the placenta and nutritional status. This study was conducted on consenting, full-term, obstetric patients (n=54), delivering in a hospital in Tijuana, Baja California (BC), Mexico.

[Prenatal care in the border city of Tijuana, Mexico].

This study was intended to explore the conditions under which prenatal care is delivered in the border city of Tijuana, Baja California, Mexico, and to assess the possible associations between that care and neonatal results in terms of birthweight, health of the neonate, and prematurity. Seven hospitals serving persons from different socioeconomic strata were chosen, and between December 1993 and March 1994 interviews were conducted with 279 women who were in the first 24 to 48 hours of puerperium. During the interviews data were collected on socioeconomic level; the mothers' knowledge, attitudes, and practices concerning obstetric health; the mothers' perceptions of access to prenatal care; the quality of prenatal care visits (evaluated in terms of having blood and urine tested and weight and blood pressure measured); and the gynecological and obstetric and health history of the mother.

[The relationship between health and job quitting in female workers of the electronics assembly industry in Tijuana].

Objective: To examine the health, labor and social factors which contribute to quitting work in two transnational electronic parts factories in Tijuana, Mexico.

Material And Methods: A cohort study of 725 women employed either at a Japanese or an American electronic parts factory in Tijuana was performed between January 1992 and March 1994. The sample was stratified in two time intervals < or = 30 or > 30 days of work.

Drug-resistant pulmonary tuberculosis in the Baja California-San Diego County border population.

A study was conducted to determine the frequency of, and risk factors for, drug-resistant pulmonary tuberculosis (TB) among Baja California (BC) and San Diego County (SDC) residents. Another purpose was to document the amount of contact between pulmonary TB patients and residents of the opposite side of the the border. During the period from February 1995 to May 1996, pulmonary TB patients from BC (n = 427) and SDC (n = 331) were evaluated with cultures, drug susceptibility tests, and questionnaires.
