Objective To examine the relationship between smoking and tobacco-related mortality in a cohort of the aged Chinese armymen.Methods A cohort study was carried out in Xi'an,China from 1987 to 2005.A total of 1 268 retired male military cadres aged 55 or older were examined in 1987 and followed up in the next 18 years.At baseline,388 men were non-smokers,461 were former smokers,and 419 were current smokers.The current smoking rate was 33.04%,Quitted rate was 52.39%.The terminal main observation items included all-cause and tobacco-associated mortality.Results Up to Jun 30,2005,a total of 491 subjects died.Compared with non-smokers,the relative risks(95% confidence intervals(CI)) of ever-smokers for all-cause deaths,chronic obstructive pulmonary disease(COPD),lung cancer,and coronary heart disease(CHD) were 1.24(1.01-1.53),1.91(1.06-3.46),2.91(1.36-6.23),and 1.15(0.68-1.93),respectively.Compared with current smokers,the risks of total mortality and death from lung cancer for former smokers were decreased by 66.7% and 14.98%,respectively.Conclusions Cigarette smoking was a major death risk factor in the cohort and quitting smoking could save lives.

Chinese Journal of Prevention and Control of Chronic Diseases.2006;0(01):-.

Objective To explore the relationship between Body Mass Index (BMI), Waist-Hips-Ratio (WHR) and Blood lipids.Methods Body measurements including BMI, WHR and body fat percentage (FAT%), and blood lipid profile assessment and liver ultrasonography were conducted on 350 employees from Shanghai Waigaoqiao Free Trade Zone from January 2006 to August 2007. All subjects were classified into a group of overweight/obesity and a group of normal body weight based on their BMI. BMI, WHR, FAT%, blood lipid profile, the prevalence of fatty liver and dyslipidemia were compared between the two groups. Results WHR, FAT%, the level of TG and TC in overweight/obesity group were significantly higher than that in normal body weight group(P=0.000), but the level of HDL-C was significantly lower than that in normal body weight group (P=0.000). The prevalence of central obesity (88.70%), fatty liver (72.32%), and hypertriglyceridemia (49.7%),hypercholesterolemia (33.89%), low HDL-C (40.68%) in overweight/obesity group were significantly higher than those in normal body weight group (P=0.000). Concludes BMI, WHR were associated with blood lipids. Early identification and intervention on these people with high risk of cardiovascular diseases are possible by body measurement, which are significant for predicting and reducing the occurrence of cardiovascular diseases.

Objective To investigate.the survival rates in a follow-up group of patient with primary liver cancer.Methods The follow-up data of new primary liver cancer cases between year 2001-2004 in Xuhui district was investigated.The age distribution of patients was described.Survival rate was analyzed with single and multiple Cox proportional hazards regression model,respectively.Results The age proportion distribution of patients showed double apexes with one in age 45～50 and another in age 70～75.The arithmetic mean of survival month was 16.4 with 95%CI 14.8～18.1 and median month was 6.9.It was no significance between male and female.Patients who had liver operation owned longer survival time,RR=0.315 5(95%CI 0.243 2～ 0.4093).The sutdy showed 5-year survival rate was 40.90%and 3.95%for patients with or without operation,respectively.It had no significant effect on survival time by gender,age and family history.Conclusion The screening test and intervention in high-risk people shall be done preferentially before peak age,so as to find primary liver cancer earlier,and the more patients can accept a suitable surgery care,the more they can obtain longer survival time.

Objective To explore the risk factors for asthma in children.Methods A 1:1 matched and hospital-based case-control study was conducted to analyses risk factors for asthma in 300 pairs of children by logistic regression analysis. Results The result of univariate Logistic regression analysis showed that there were 17 related factors for children asthma, including disease history of parents in respiratory system,family income,atopie character,history of acute respiratory infections, eating habit,the amount of sea foods intakes,foam plastics,family decoration,the way of exhaust fume in kitchen,the exhaust effectiveness,raising pet in house,family history of asthma,family history of allergic rhinitis,family history of food allergy,dust allergy of parents,systemic therapy after the first attack.With multivariate Logistic regression analysis,7 factors were entered the model,6 risk factors including father's history of respiratory diseases(OR 3.771,95%CI 1.533～9.278),low family income(OR 1.503, 95%CI 1.258～1.795),atopy(OR 3.788,95%CI 2.368～6.058),meat-eating habit(OR 2.042,95%CI 1.481～2.815),asthma history of family members(OR 1.710,95%CI 0.988～2.958),the family history of allergic rhinitis(OR 1.991,95%CI 1.234～3.211), and 1 protective factor of raising pet in house(OR 0.443,95%CI 0.265～0.739).The coefficients of these factors in multivariate logistic regression model were 1.327、0.407、1.322、0.714、0.536、0.689、and-0.814 respectively.Conclusion Children asthma was a multi-factorial complex disease,and the interaction of environmental and genetic risk factors played an important role in the onset of this disease.

Objective To investigate the hazard of hypertension at initial diagnosis ages.Methods Using stratified cluster sampling,6 091 adults aged more than 18 years with/without hypertension were interviewed;meanwhile their blood pressures were measured.The hazard of hypertension at initial diagnosed age was analyzed with survival analysis.Results The prevalent rate of hypertension was 19.9%and the average initial diagnosed age of hypertension was 52.0?13.12)yrs.The hazard persistently increased with the age after 35 years old for male,and reached its peak of prevalent rate(26%)at the age of 75 years for female.Not significant difference of hazard existed between male and female.Conclusion Our data indicated that there is a close relationship between the risk of hypertension onset and the age,the hazard increasing with ages,especially for the population aged over 35 years old.Therefore,an early prevention of hypertension should be taken from adolescent period.
