Background: Most oral cancers are squamous cell carcinomas (90%) which are two to four times more common in men than in women. The reasons for these differences are associated with exposure to factors such as tobacco and alcohol. Age is also considered as a risk factor (about 90% of the cases are diagnosed after 45 years of age). Aim: To analyze the frequency of oral cavity cancer during the last years in Chile. Material and methods: Mortality rates were obtained from death records of the "Instituto Nacional de Estadísticas" and publications of the World Health Organization, from 1955 to 2002. Morbidity from 1969 to 2002 was obtained from hospital discharge records of the Chilean Ministry of Health. Results: Oral cancer corresponded to 1.6% of total cancer cases in Chile, with a male:female ratio of 2.3 to 1. Deaths due to oral cancer was 1% of all cancer deaths, with a male:female ratio of 2.8 to 1. The morbidity rate for both genders increased while the mortality rate was relatively constant. However, we observed an increase in the mortality rate among women from 1980 to 2002, associated with more than 100% increase in the frecuency of smoking, between 1970 and 1998. The most common anatomical location was the tongue. Conclusions: The incidences of oral cancer is increasing in Chilean women, but men are more commonly affected (Rev Méd Chile 2005; 133: 555-63).

... Estudios realizados últimamente indican que esta frecuencia se ha mantenido estable, con una prevalencia superior a 40%. Se debe también mencionar que se ha comprobado un alarmante consumo en los adolescentes y adultos jóvenes, en quienes la prevalencia sería superior a 55%, observándose además, un incremento de este hábito en las mujeres y una disminución en la edad de inicio de su consumo 14 . ...

Background: Smoking is the main risk factor for Chronic Obstructive Pulmonary Disease (COPD), an important cause of morbidity and mortality. Aim: To estimate smoking attributable risk and population attributable risk in COPD patients attended in Public Health Services of Santiago. Materials and methods: A case control study matched by sex and age was carried out. Crude and adjusted attributable risks as well as population attributable risk were estimated, controlled by potential confounders and by interaction variables. Results: Mean ages for cases and controls were 68 and 67 years respectively. When compared to the control group, COPD patients had a higher smoking prevalence (at least 100 cigarettes in their life span: 89.7% vs 60.3%; p <0.01). Among COPD patients, heavy smokers proportion was 4 times higher than in controls, they smoked for more years (43 vs 31; p <0.01) and more cigarettes per day (18 vs 5; p <0.01). Adjusted attributable risk was 87% (95% Confidence Interval (CI): 63.7-94.8). If a patient smoked at least 100 cigarettes in his/her life span and this risk was 92.7% (CI: 82.4-96.9) for heavy smokers. Projecting this index to Santiago inhabitants, about 87,000 individuals older than 40 years would be suffering COPD due to smoking. Conclusions: This article confirms the strong association between smoking and COPD. Attributable risks are high and significant, even when they are adjusted by confounding variables. Women had a higher risk than men, at lower levels of tobacco consumption Financiado por la Organización Panamericana de la Salud.

Introduction: in this century has been an unusual increase of smoking, habit that is the more important risk factor for development of ventilatory limitation, such action has became a problem in the health staff. Objective: to determine the possible repercussion of smoking on the pulmonary function. A cross-sectional and descriptive study was conducted in smokers working in the Dr. Carlos J. Finlay Central and Military Hospital. Sixty smokers underwent a spirometry study. Results: there was predominance of female sex from the 40 and 49 age-groups. The assistant staff was the group with a greater figure of smokers. Cigarette was the more consumed toxic agent. Also, there was predominance of moderate smokers (11-20 cigarettes by day) during more of 21 years with the greater figure of patients with respiratory symptoms. Conclusions: the predominant spirometry pattern was normal, but there was a significant percentage of smokers presenting with an obstructive ventilatory dysfunction, showing the damage to pulmonary function in the smokers staff.

Introduction and objectives Laryngeal cancer is the second most common respiratory cancer worldwide. In Chile, national registries of cancer incidence do not exist, only mortality statistics are available. The aim of this study is to analyze the trends in mortality rates from laryngeal cancer in Chile, during the period between 1990 and 2004, and its distribution by sex and age. Material and method The totalities of the deaths caused by laryngeal cancer were selected from the official mortality databases (1990-2004), and the projections of population elaborated by the National Statistics Institute were used for the calculation of age- and sex-adjusted mortality rates. Results In Chile, during the period studied a total of 1842 deaths caused by laryngeal cancer occurred, of which 85.78 % corresponded to men and 14.22 % to women. The crude and adjusted incidence rates were 0.90 and 0.82 per 100 000 inhabitants, respectively. They were greater in men, increased progressively with age, and diminished over time throughout the period studied. Conclusion Laryngeal cancer in Chile presented a constant decline over the period studied. Sex-and age-distributions were similar to international data. A substantial part of this decline could be explained by the increase in mortality from other causes and by therapeutic and diagnostic improvements.

Background: The association between lung cancer and smoking is well documented. However there is less information about the estimation of its attributable fraction and population burden. Aim: To estimate the attributable risk and population attributable risk of smoking among lung cancer patients attended in Public Health Services at Santiago. Material and methods: A case control study matched by age was carried out. Crude and adjusted attributable and population attributable risks were estimate, controlling for potential confounders and interaction variables. Results: Mean age for cases was 63 years for women and 67 years for men. Lung cancer patients had a higher smoking prevalence than controls (64.5% and 39.7% respectively among women: 95.8 and 67.1 respectively among men p <0.01). Heavy smoker proportion was 4 times higher among patients that smoked 5 to 10 years more (women and men respectively, p <0.01) and 3 times more cigarettes per day (p <0.01). attributable risk for women was 64.4% and 90.4% for men. Population attributable fraction was 41.9% and 86.3% for women and men, respectively. Projecting these estimates to the Chilean population, approximately 1975 new cases per year of lung cancer caused by smoking will be diagnosed. Conclusion: Attributable risks of smoking for lung cancer are high and significant, even when they are adjusted by confounding variables.

The aims of the study were to describe the trend in birthweight from 1985 to 2000 in Chile and ascertain the possible factors that may explain the changes in birthweight during the period. We used time series of birthweight and length at birth of all live births (n > 4,000,000). Multivariable regression analyses were carried out to assess whether the gender of the newborn, maternal education, maternal age and marital status could explain the trend in the total time series and by period. Birthweight adjusted for gestational age was analysed in terms of grams and Z scores. There was an increase in birthweight of 100 g between 1989 and 1994 that coincided with the re-establishment of democracy and economic growth in Chile. The changes in birthweight were not explained by the available independent variables and trends of caesarean section, maternal obesity and post-mature deliveries over the period. The birthweight difference between mothers with university education and those with primary education was 0.2 Z scores (equivalent to 110 g) in 1985 and was greatly reduced by 2000 (equivalent to 40 g). A positive sense of social well-being and economic growth may have influenced an increase in birthweight between 1989 and 1994 as socio-economic growth preceded and continued after the period of increasing birthweight. Our study showed a remarkable decrease in the differences in birthweight by educational level not shown in other countries of similar wealth.
