OBJECTIVES: The purpose of this study was to identify behaviors associated with change in body mass index or with weight gain at the waist. METHODS: A cohort of 79236 White, non-Hispanic, healthy adults was questioned in 1982 and 1992 about diet and 10 physical activities. Estimates were made of the mean effects of stable behaviors on 10-year change in body mass index and on odds ratios for gain at the waist. RESULTS: Ten-year changes in body mass index was associated positively with meat consumption and smoking cessation and inversely with vegetable consumption, vitamin E supplementation, continued smoking, and some vigorous activities (e.g., jogging/running). Women's body mass index decreased with walking 4 or more hours per week and with regular alcohol intake, but these behaviors had a smaller effect on men's body mass index. weight gain was inversely associated with high vegetable consumption, walking 4 or more hours per week, and jogging/running 1 to 3 hours per week but not with less demanding physical activities. CONCLUSIONS: Simple derivation of behaviors associated with weight loss or reduced abdominal obesity may enhance programs designed to prevent obesity and chronic diseases.

Background We investigated the effect of influenza vaccination on disease severity in adults hospitalized with laboratory-confirmed influenza during 2013–14, a season in which vaccine viruses were antigenically similar to those circulating. Methods We analyzed data from the 2013–14 influenza season and used propensity score matching to account for the probability of vaccination within age strata (18–49, 50–64, and ≥65 years). Death, intensive care unit (ICU) admission, and hospital and ICU lengths of stay (LOS) were outcome measures for severity. Multivariable logistic regression and competing risk models were used to compare disease severity between vaccinated and unvaccinated patients, adjusting for timing of antiviral treatment and time from illness onset to hospitalization. Results Influenza vaccination was associated with a reduction in the odds of in-hospital death among patients aged 18–49 years (adjusted odds ratios [aOR] = 0.21; 95% confidence interval [CI], 0.05 to 0.97), 50–64 years (aOR = 0.48; 95% CI, 0.24 to 0.97), and ≥65 years (aOR = 0.39; 95% CI, 0.17 to 0.66). Vaccination also reduced ICU admission among patients aged 18–49 years (aOR = 0.63; 95% CI, 0.42 to 0.93) and ≥65 years (aOR = 0.63; 95% CI, 0.48 to 0.81), and shortened ICU LOS among those 50–64 years (adjusted relative hazards [aRH] = 1.36; 95% CI, 1.06 to 1.74) and ≥65 years (aRH = 1.34; 95% CI, 1.06 to 1.73), and hospital LOS among 50–64 years (aRH = 1.13; 95% CI, 1.02 to 1.26) and ≥65 years (aRH = 1.24; 95% CI, 1.13 to 1.37). Conclusions Influenza vaccination during 2013–14 influenza season attenuated adverse outcome among adults that were hospitalized with laboratory-confirmed influenza.

The key epidemiologic features of a measles outbreak in the Amish community in Ohio were transmission primarily within households, the small proportion of Amish people affected, and the large number of people in the Amish community who sought vaccination. As a result of targeted containment efforts, and high baseline coverage in the general community, there was limited spread beyond the Amish community.

Context.-Cancer registries have reported an increased incidence of melanoma and certain noncutaneous cancers following nonmelanoma skin cancer (NMSC). Whether these findings were attributable to intensified surveillance, shared risk factors, or increased cancer susceptibility remains unclear. Objective.-To determine whether a history of NMSC predicts cancer mortality. Design.-Prospective cohort with 12-year mortality follow-up adjusted for multiple risk factors. Setting.-Cancer Prevention Study II, United States and Puerto Rico. Participants.-Nearly 1.1 million adult volunteers who completed a baseline questionnaire in 1982. Main Outcome Measure.-Deaths due to all cancers and common cancers. Results.-After adjusting for age, race, education, smoking, obesity, alcohol use, and other conventional risk factors, a baseline history of NMSC was associated with increased total cancer mortality (men's relative risk [RR], 1.30; 95% confidence interval [

The authors examined the relation between smoking and the risk of fatal prostate cancer in a large prospective mortality study of 450,279 men who were cancer free at enrollment in 1982. During 9 years of follow-up, 1,748 deaths occurred from prostate cancer. Cox proportional hazards modeling was used to adjust for other risk factors. Current cigarette smoking was associated with fatal prostate cancer (rate ratio = 1.34, 95% confidence interval (CI) 1.16-1.56). The rate ratio was greater at younger ages, decreasing from 1.83 (95% CI 1.04-3.24) among men below the age of 60 years to 1.11 (95% CI 0.79-1.58) among men aged 80 years and above (p for trend = 0.16). No trend in risk was observed with the number of cigarettes per day or with the duration of smoking among current smokers at baseline, and no increased risk was found among former smokers. Race did not significantly modify the association between cigarette smoking and fatal prostate cancer. These data, together with those of three other large prospective studies that find higher death rates from prostate cancer in current cigarette smokers, and inconsistent findings in incidence studies suggest that smoking may adversely affect survival in prostate cancer patients.
