The data collected showed that lung cancer ncidence and mortality rates ranks first among all other malignant tumor and had been on the increase from year to year. The mortality rate in urban area was higher than that in its suburbs. While the male incidence was higher than that of the female. The sex ratio of the male to female incidence rates was 1.56. The incidence rate rises with age. The lung cancer is one of the lesser prevised cancer and the five-year relative survival rate is 6.5% for both sexes in 19S2 ?1983. The lung cancer mortality rate in Beijing urban area is compared in this report with other countries in the world, and it is found that the female mortality rate of lung cancer in Beijing is among the highest.展开更多

Data on demographic features, lifestyle or dietary habits, health status, living environment conditions, sleep and mental status, and asthenopia symptoms were collected through a self -administered validated questionnaire. Univariate logistic regression and multivariate logistic regression analysis modified by the factor analysis were performed to evaluate risk factors for asthenopia. ·RESULTS: Fifty-seven percent of the college students complained of asthenopia. Statistically significant risk factors for asthenopia in the univariate analysis included 13 variables. Multivariate analysis revealed a significant relationship between the use of computer and asthenopia (OR 1.21, 95% CI: 1.09 to 1.35). Good sleep and mental status (OR 0.86, 95% CI: 0.76 to 0.97), good living environment conditions (OR 0.67, 95% CI: 0.60 to 0.76), and high intake of green leafy vegetables (OR 0.89, 95% CI: 0.80 to 0.98) were found to be strong predictors of decreasing the occurrence of asthenopia complaints. ·CONCLUSION: Asthenopia symptom appeares to be common among college students; and it is strongly associated with computer use, psychosocial state, environment conditions and dietary habits, suggesting that additional studies are warranted to verify these risk factors and establish prevention guidelines, especially for college students. ·展开更多
