Mortality among production workers in pulp and paper mills.

A cohort of 3,572 pulp and paper mill workers employed for at least one year between 1945 and 1955 was followed through 31 March 1977. Vital status was determined for 99% of the cohort. The 915 deaths observed were 79% of the number expected on the basis of comparable United States mortality rates. Statistically nonsignificant excesses of deaths due to lymphosarcoma and reticulosarcoma and to stomach cancer were observed. These findings tend to corroborate reports based on state vital statistics, and preliminary case-referent and population-based studies of workers in the pulp or paper industries. No deaths due to nasal cancer were observed, but only 0.6 were expected. When process-specific analyses were conducted, the excess risk of lymphosarcoma and reticulosarcoma was increased only for men who worked in sulfate mills. The excess risk of stomach cancer was limited to men who worked in sulfite mills. Process-specific standardized mortality ratios for these causes were highest after 20 years since first employment in the mills.

Prenatal participation in WIC related to Medicaid costs for Missouri newborns: 1982 update.

This study replicates a 1980 evaluation of WIC prenatal participation in Missouri by using a file of 9,086 Missouri Medicaid records matched with the corresponding birth records. This file was divided into a WIC group containing 3,261 records and a non-WIC group of 5,825 records. The 1982 results generally confirm the 1980 results, with the 1982 findings showing slightly improved pregnancy outcomes for WIC participants and slightly reduced benefit-to-cost ratios compared with the 1980 findings. In 1982, WIC participation was found to be associated with an increase in mean birth weight of 31 grams and reductions in low birth weight rates (statistically significant) and in neonatal death rates (not statistically significant). The reduction in each rate was 23 percent. WIC participation was also associated with a reduction in Medicaid costs for newborns reported within 45 days of birth amounting to $76 per participant. For every dollar spent on WIC, about 49 cents in Medicaid costs were apparently saved. However, wide 95 percent confidence intervals ($.07, $.90) make it difficult to determine precisely what impact WIC has on Federal and State budget outlays.

Differential features of motor neuron disease mortality in Spain.

BACKGROUND: The objective of this study was to describe the temporal and spatial patterns of motor neuron disease (MND) in Spain. METHODS: We studied data where MND was stated as the principal cause of death in official statistics from Spain. Time trends were analysed for age-, sex-specific and age-adjusted rates for the period 1951-1990. Age-adjusted mortality and relative risk, obtained by Poisson regression adjusting for age, were calculated for each province from deaths during the period 1975-1988. Maps were constructed using log transformed rates. Statistical significance of spatial aggregation was assessed using the Ohno et al. test. RESULTS: The 1951-1990 mortality rate, age- and sex-adjusted to the European population, for the population aged > or = 40 years was 1.49 per 100,000; 1.90 and 1.21 for males and females respectively. In general, mortality increased with age. Age-adjusted rates rose until 1960, dropped by 70% during the 1960s and declined slightly over the 1951-1990 period as a whole. From 1970 onwards MND mortality rose evenly, particularly in the 60-69 age group. A North-South gradient was suggested for both sexes with statistically significant clustering in the Northern coastal regions and--for males alone--in the Midwest provinces. CONCLUSIONS: Mortality from MND in Spain displayed a magnitude and recently rising temporal trend similar to that described in several other countries. Specific traits were: a decrease during the 1960s, which has been described for Japan only, as well as spatial heterogeneity and a predominant recent increase among the 60-69 age group. The determinants of these unusual MND mortality patterns are unknown.

Consumption of meat and fruit in relation to oral and esophageal cancer: a cross-national study.

Using data from 59 countries, we conducted an international comparison study to identify nutritional predictors of age-adjusted oral and esophageal cancer mortality rates. Statistical models accounted for per capita tobacco disappearance data, alcohol consumption, and various measures of socioeconomic status. For oral cancer, stepwise regression results showed protective effects for milk/dairy products (B = -0.030, p < 0.0001) and cabbage consumption (B = -0.391, p = 0.01) and increased risk from vegetable oil (B = 0.072, p = 0.04) and excess animal fat calories (B = 0.344, p < 0.0001) as well as marginally increased risk from cereals (B = 0.008, p = 0.08). Results were obtained after accounting for all background factors, including sex (model R2 = 0.52). For esophageal cancer, stepwise results indicated protective effects for fruit (B = -0.046, p = 0.0006) and total caloric intake (B = -0.013, p < 0.0001) and increased risk from vegetable oil (B = 0.061, p = 0.04) and meat (B = 0.031, p < 0.0001) consumption (model R2 = 0.55). When analyzed separately by sex, results were similar, indicating that the risk factors are probably the same in both sexes, even though women consistently have fewer deaths, on average, from these cancers. On the basis of results from stepwise regression models, we also fitted general linear models for mortality rates of each cancer site, and results were similar in terms of magnitude and direction of effects. Although the evidence provided by this type of analysis using data aggregated by country is limited in terms of control for potential confounding effects and modeling of possible effect modification, an effect of high meat, animal product, or vegetable oil and low fruit and cabbage consumption is consistent with the known biology of these tumors.

Black/white comparisons of deaths preventable by medical intervention: United States and the District of Columbia 1980-1986.

Blacks in the US experience increased mortality (1113 versus 745 per 100,000 males; 631 versus 411 per 100,000 females) and decreased life expectancy (63.7 years versus 70.7 years for males; 72.3 years versus 78.1 years for females); compared to Whites. In an effort to determine if the excess mortality among Black Americans might be explained by differences in access or quality of health care services, we performed a race-specific analysis of conditions for which mortality is largely avoidable given timely and appropriate medical care. Using methodology proposed by Rutstein and Charlton, mortality due to 12 causes was evaluated including tuberculosis, cervical cancer, Hodgkin's disease, rheumatic heart disease, hypertensive heart disease, acute respiratory disease, pneumonia and bronchitis, influenza, asthma, appendicitis, hernias and cholecystitis. In the US, during 1980 to 1986, an average of 17,366 deaths and 286,813 years of potential life (YPLL) before age 65 were lost each year due to all 12 sentinel causes combined. Of these causes, hypertensive heart disease, pneumonia and bronchitis, cervical cancer and asthma accounted for the greatest number of deaths. The mortality rate for all 12 causes combined among Blacks was 4.5 times that of Whites. The highest relative rates among Blacks compared to Whites were observed for tuberculosis, hypertensive heart disease and asthma. The overall mortality rate in the District of Columbia for the selected causes was 3.7 times the national rate. Compared to national rates, statistically significant elevated rates in the District were observed for tuberculosis, hypertensive heart disease and pneumonia and bronchitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of advance directives on the management of elderly critically ill patients.

OBJECTIVE: To evaluate the effects of advance directives on the management of elderly, critically ill patients. DESIGN: Retrospective chart review. SETTING: Teaching hospital medical/surgical, noncardiac intensive care unit (ICU). PATIENTS: The medical records of 401 patients, > or =65 yrs of age, admitted to the ICU between 1992 and 1995 were reviewed. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Advance directive statements included refusal of cardiopulmonary resuscitation (CPR), nutrition, intravenous medications, antibiotics, mechanical ventilation, and blood products. Nineteen (5%) patients had advance directives (study group). These patients were compared with 28 case-matched (age, Acute Physiology and Chronic Health Evaluation II score, and diagnosis) critically ill patients without advance directives (control group). We compared the following data: cost per day; number of surgical procedures; number of radiographic studies; number of central venous and pulmonary artery catheter insertions; number of complete blood counts, electrolytes, and cultures sent for laboratory testing; number of days in the ICU/hospital; and mortality rates. Statistical analysis was performed using the Student's t-test for independent means and the chi-square equation. For all observed parameters, quantitative and dichotomous differences between study and control groups were not statistically significant. Two patients received CPR, despite advance directive statements refusing this treatment. CONCLUSIONS: Few critically ill seniors have advance directives. As assessed by objectively documented information, the level of care delivered to elderly ICU patients is not affected by the presence or absence of advance directive statements. Medical personnel need to be aware of whether or not patients have advance directive statements, as unauthorized CPR was administered to 11% of the patients who died with advance directives.
