Abstract: abstract smoking in presently one of the most important public health problems worldwide. even though smoking is a preventable cause of morbidity and mortality, it still contributes importantly to the burden of disease. in mexico, contrary to what is happening in other parts of the world, the smoking epidemic is in an early phase, as evidenced by the low number of lung cancer cases or deaths, and by the minimal public health efforts to control tobacco consumption. one of the most important advances is its recognition as a priority public health problem by public health workers and society in general. effective interventions to reduce tobacco consumption have been launched to render the country free of tobacco. these public health interventions are being countered by the tobacco industry and the market forces that strive to preserve smoking as a life style of the population. the present work reviews the production means of the mexican tobacco industry, particularly those of cigarettes, the market structure, and the product expansion in the mexican population. this information should be useful to frame effective preventive measures, in the short and long term, to control this epidemic.
La industria tabacalera en México

Abstract: El tabaquismo es uno de los problemas de salud pública más importantes del siglo pasado y del presente. Lo paradójico de la práctica de la salud pública es que el tabaquismo es un evento totalmente prevenible que ha estado presente en el desarrollo de la sociedad, contribuyendo de manera importante en la morbilidad y mortalidad, aun a costa de la evolución que ha tenido la salud pública mundial. En el caso de México, al contrario que en otras partes del mundo, la ola epidémica del tabaquismo se encuentra en su primera fase, expresada en la morbilidad y mortalidad asociadas, como el cáncer pulmonar, así como por las mínimas actividades preventivas instrumentadas; pero un buen avance ha sido el reconocimiento que como problema prioritario de salud se ha dado por los trabajadores de la salud pública y la sociedad. Se han iniciado las acciones de intervención tendientes a disminuir el consumo de tabaco entre la población y, con ello, dejar sembrado el camino de la prevención para futuras generaciones libres de tabaco. Frente a estas acciones de intervención se encuentran la industria tabacalera y los mecanismos de reproducción del mercado que opera para mantener el consumo de tabaco como un hábito de vida poblacional. El presente trabajo revisa los mecanismos de producción del tabaco, en especial de los cigarrillos, así como la comercialización, estructura del mercado y penetración del producto en la población mexicana, para contribuir con elementos de comprensión de la epidemia mexicana de tabaquismo para la implantación de medidas preventivas exitosas, presentes y futuras, para el control de la epidemia.

Abstract: objetive. to describe the geographical coverage of the mexican healthcare system (mhs) services and to assess the utilization of its general hospitals. material and methods. a geographic information system (gis) was used to include sociodemographic data by locality, the geographical location of all mhs healthcare services, and data on hospital discharge records. a maximum likelihood estimation model was developed to assess the utilization levels of 217 mhs general hospitals. the model included data on human resources, additional infrastructure, and the population within a 25 km radius. results. in 1998, 10,806 localities with 72 million inhabitants had at least one public healthcare unit, and 97.2% of the population lived within 50 km of a healthcare unit; however, over 18 million people lived in rural localities without a healthcare unit. the mean annual hospital occupation rate was 48.5 ± 28.5 per 100 bed/years, with high variability within and between states. hospital occupation was significantly associated with the number of physicians in the unit, and in the mexican institute of social security units utilization was associated with additional health infrastructure, and with the population's poverty index. conclusions. gis analysis allows improved estimation of the coverage and utilization of mhs hospitals.

Abstract: Objective. To assess the reproducibility and validity of a 116 item semi-quantitative food frequency questionnaire (FFQ), designed to assess the relation between dietary intake and chronic diseases. Material and methods. To test the reproducibility of the FFQ questionnaire, the FFQ was administered twice to 134 women residing in Mexico City at an interval of approximately one year; to assess the validity we compared results obtained by the FFQs with those obtained by four 4-day 24-hour recalls at three month intervals. Validity and reproducibility were evaluated using regression analysis and Pearson and intraclass correlation coefficients of log-e and calorie-adjusted nutrient scores. Results. Mean values for intake of most nutrients assessed by the two food frequency questionnaires were similar. However, means for the 24-hr recall were significantly lower. Intraclass correlation coefficients for nutrient intakes, assessed by questionnaires, administered one year apart, ranged from 0.38 for cholesterol to 0.54 for crude fiber. Correlation coefficients between energy-adjusted nutrient intakes, measured by diet recalls, and the first FFQ ranged from 0.12 for polyunsaturated fatty acids to 0.67 for saturated fatty acids. Regression coefficients between 24-hr recall and FFQ,s were all significant were significant for all nutrients, except for polyunsaturated fat, folic acid, vitamin E and Zinc. Conclusions. These data indicate that this semi-quantitative FFQ is reproducible and provides a useful estimate by which to categorize individuals by level of past nutrient intake. However, its application outside Mexico City or in different age and gender populations will require additional modifications and validation efforts.
