Excess mortality among cigarette smokers: changes in a 20-year interval.

OBJECTIVES: This study was undertaken to examine changes in smoking-specific death rates from the 1960s to the 1980s. METHODS: In two prospective studies, one from 1959 to 1965 and the other from 1982 to 1988, death rates from lung cancer, coronary heart disease, and other major smoking-related diseases were measured among more than 200,000 current smokers and 480,000 lifelong non-smokers in each study. RESULTS: From the first to the second study, lung cancer death rates (per 100,000) among current cigarette smokers increased from 26 to 155 in women and from 187 to 341 in men; the increase persisted after current daily cigarette consumption and years of smoking were controlled for. Rates among nonsmokers were stable. In contrast, coronary heart disease and stroke death rates decreased by more than 50% in both smokers and nonsmokers. The all-cause rate difference between smokers and nonsmokers doubled for women but was stable for men. CONCLUSIONS: Premature mortality (the difference in all-cause death rates between smokers and nonsmokers) doubled in women and continued unabated in men from the 1960s to the 1980s. Lung cancer surpassed coronary heart disease as the largest single contributor to smoking-attributable death among White middle-class smokers.

Excess mortality among urban residents: how much, for whom, and why?

OBJECTIVES: The goals of this study were to estimate prospective mortality risks of city residence, specify how these risks vary by population subgroup, and explore possible explanations. METHODS: Data were derived from a probability sample of 3617 adults in the coterminous United States and analyzed via cross-tabular and Cox proportional hazards methods. RESULTS: After adjustment for baseline sociodemographic and health variables, city residents had a mortality hazard rate ratio of 1.62 (95% confidence interval [CI] = 1.21, 2.18) relative to rural/small-town residents; suburbanites had an intermediate but not significantly elevated hazard rate ratio. This urban mortality risk was significant among men (hazard rate ratio: 2.25), especially non-Black men, but not among women. Among Black men, and to some degree Black women, suburban residence carried the greatest risk. All risks were most evident for those younger than 65 years. CONCLUSIONS: The mortality risk of city residence, at least among men, rivals that of major psychosocial risk factors such as race, low income, smoking, and social isolation and merits comparable attention in research and policy.

How can we combat excess mortality in Harlem: a one day survey of substance abuse in adult general care.

Our hypothesis was that a one-day survey of all patients hospitalized on Adult General Care would demonstrate a need for expanded addiction services in a municipal teaching hospital in East Harlem. We interviewed 276 patients in Adult General Care on February 16, 1990 to assess whether they abused drugs or alcohol or were hospitalized for reasons related to substance use. Of the 276 patients interviewed, 18 percent used alcohol alone, 14 percent used drugs alone, 17 percent used both drugs and alcohol and 2 percent were hospitalized for reasons related to substance use. One hundred forty or 51 percent of all patients were admitted because of substance use and its sequelae or as a result of violence associated with the buying or selling of drugs. The percentage was highest on one medical floor where 89 percent of the patients were substance users and on medical floors in general where the average was 60 percent. Forty patients or 14 percent were known to be HIV seropositive. Given the high mortality in Harlem, the results of our one-day survey indicate a need for expanded addiction services.

Excess mortality associated with antimicrobial drug-resistant Salmonella typhimurium.

In a matched cohort study, we determined the death rates associated with drug resistance in Salmonella Typhimurium. We linked data from the Danish Surveillance Registry for Enteric Pathogens with the Civil Registration System and the Danish National Discharge Registry. By survival analysis, the 2-year death rates were compared with a matched sample of the general Danish population, after the data were adjusted for differences in comorbidity. In 2,047 patients with S. Typhimurium, 59 deaths were identified. Patients with pansusceptible strains of S. Typhimurium were 2.3 times more likely to die 2 years after infection than persons in the general Danish population. Patients infected with strains resistant to ampicillin, chloramphenicol, streptomycin, sulfonamide, and tetracycline were 4.8 times (95% CI 2.2 to 10.2) more likely to die, whereas quinolone resistance was associated with a mortality rate 10.3 times higher than the general population.

Modelling excess mortality of the unemployed: choice of scale and extra-Poisson variability.

"Occupational mortality and morbidity is usually studied via standardized mortality (or morbidity) ratios, with little attention to the basic fit of the implicit underlying proportional hazards model. This paper presents a case study on unemployment and mortality, based on the complete Danish male population aged 20-64 years at the 1970 census. The effect of unemployment on the age-specific mortality rate is intermediate between additive and multiplicative and was fitted well by an additive effect on the square root of the mortality. The paper discusses and illustrates whether finer stratification or random residual variation ('frailty') is to be preferred for obtaining a statistically satisfactory fit."
