To investigate acute, irreversible effects of exposure to ozone and other air pollutants, the authors examined daily death counts in relation to air pollution levels in Mexico City during 1990-1992. When considered singly in Poisson regression models accounting for periodic effects, the rate ratio for total mortality associated with a 100-ppb increment in(More)
Since its introduction in Mexico in 1998, the use of automated peritoneal dialysis (APD) has grown steadily and now 35% of Mexican patients are being treated with it. Peritonitis continues to be the most important infectious cause of drop out in peritoneal dialysis (PD) programs and naturally has an impact on technique survival. The objective of this study(More)
OBJECTIVE To determine the temporal mortality trends of uterine cervical cancer in Mexico for the period 1980-1990. STUDY DESIGN In Mexico, data from death certificates are collected in a national repository at the National Institute of Statistics, Geography and Informatics. These data were analyzed to obtain mortality trends, and regional variations were(More)
BACKGROUND Epidemiological data on impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) based on a representative Mexican sample are not available; thus, the objectives of this study were to determine the prevalence and distribution of IFG and IGT, and to establish its relationship with obesity in Mexican adults. METHODS We performed a(More)
BACKGROUND Despite certain contradictions, an association has been identified between adherence to drug treatment and the quality of life in patients with type 2 diabetes. The contradictions observed emphasize the importance of using different methods to measure treatment adherence, or the association of psychological precursors of adherence with quality of(More)
SETTING The city of Hermosillo, in Northwest Mexico, has a higher incidence of tuberculosis (TB) than the national average. However, the intra-urban TB distribution, which could limit the effectiveness of preventive strategies and control, is unknown. METHODS Using geographic information systems (GIS) and spatial analysis, we characterized the(More)
BACKGROUND Although several lines of evidence suggest that hypomagnesaemia is a risk factor for developing type 2 diabetes, there are no studies regarding the association between hypomagnesaemia and the risk for developing impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). Our objective was to examine the association between serum magnesium(More)
OBJECTIVE Several cutoff points of the homeostasis model assessment of insulin resistance (HOMA-IR; varying from 2.5 to 4.0) have been suggested for diagnosing IR in youth. In this study, we determined the distribution of the HOMA-IR in Mexican children and adolescents. DESIGN AND METHODS A total of 6132 children and adolescents from San Luis Potosi,(More)
BACKGROUND Cardiovascular (CV) risk factors are influenced by behavioral, cultural, and social factors, suggesting that acculturation plays a significant role in the emergency and growth of chronic disease. The objective of this study was to determine the relation between CV risk factors and the main components of acculturation, in Yaquis and Tepehuanos(More)
OBJECTIVE To determine childhood and adolescent cancer mortality by the level of marginalization in Mexico. MATERIALS AND METHODS We used 1990-2009 death certificates estimating age-standardized rates. We calculated the Average Annual Percent Change (AAPC) using the Joinpoint Regression program available at the National Cancer Institute to assess(More)
