Screening mammography use in Medicare beneficiaries reflects 4-year mortality risk.

Objective: Breast cancer screening guidelines recommend that women and physicians consider life expectancy when making screening decisions in older women. However, prior studies suggest that screening mammography patterns are dependent on age rather than health status or mortality risk of women. Our objective is to determine the association between 4-year mortality risk and use of screening mammography in women aged ≥ 65 years using Medicare Current Beneficiary Survey data.

The effect of vaccinated children on increased hepatitis B immunization among high-risk adults.

Objectives: We sought to examine trends in hepatitis B virus (HBV) vaccination among high-risk adults and assess the potential effect vaccinated adolescents have on these trends as they age.

Methods: We used data from the National Health Interview Survey 2000, 2002, and 2004 to examine trends in HBV vaccination among high-risk adults aged 18 to 49 years and in age subgroups (18-29, 30-39, and 40-49 years). We investigated temporal differences in vaccination rates for the 18- to 29-year-old cohort with model-based linear contrasts constructed from a logistic regression model with age and survey year as predictors.

Association between length of residence and cardiovascular disease risk factors among an ethnically diverse group of United States immigrants.

Background: Although differences in cardiovascular disease (CVD) risk factors between immigrants and nonimmigrants have been examined previously, the effect of acculturation on CVD risk factors in immigrants has been less well studied.

Objective: To determine the association between length of U.S.
