Student and Staff Knowledge of School Tobacco Policies and Student E‐Cigarette Use, California 2022–2023
BACKGROUND: Since 2016, California has prohibited e-cigarette use alongside smoking in K-12 schools. School tobacco policies may reduce student e-cigarette use. METHODS: We analyzed 2022 to 2023 California Healthy Kids Survey (CHKS) and School Staff Survey data (n = 219,114). Multivariable logistic regression was used to examine associations between student and staff awareness of school tobacco policies and current e-cigarette use, adjusting for …
The impact of neighborhood social and built environment factors across the cancer continuum: Current research, methodological considerations, and future directions
Neighborhood social and built environments have been recognized as important contexts in which health is shaped. The authors reviewed the extent to which these neighborhood factors have been addressed in population‐level cancer research by scanning the literature for research focused on specific social and/or built environment characteristics and their association with outcomes across the cancer continuum, including incidence, diagnosis, treatmen…
Validation of the PROMIS physical function measures in a diverse US population-based cohort of cancer patients
Impact of neighborhoods and body size on survival after breast cancer diagnosis
Racial/Ethnic and Socioeconomic Differences in Short-Term Breast Cancer Survival Among Women in an Integrated Health System
Objectives. We examined the combined influence of race/ethnicity and neighborhood socioeconomic status (SES) on short-term survival among women with uniform access to health care and treatment. Methods. Using electronic medical records data from Kaiser Permanente Northern California linked to data from the California Cancer Registry, we included 6262 women newly diagnosed with invasive breast cancer. We analyzed survival using multivariable Cox p…
The Association Between Neighborhood Characteristics and Body Size and Physical Activity in the California Teachers Study Cohort
Objectives. We considered interactions between physical activity and body mass index (BMI) and neighborhood factors. Methods. We used recursive partitioning to identify predictors of low recreational physical activity ( 2 ) among 118 315 women in the California Teachers Study. Neighborhood characteristics were based on 2000 US Census data and Reference US business listings. Results. Low physical activity and being overweight or obese were associa…
Disparities in Breast Cancer Survival Among Asian Women by Ethnicity and Immigrant Status: A Population-Based Study
Objectives. We investigated heterogeneity in ethnic composition and immigrant status among US Asians as an explanation for disparities in breast cancer survival. Methods. We enhanced data from the California Cancer Registry and the Surveillance, Epidemiology, and End Results program through linkage and imputation to examine the effect of immigrant status, neighborhood socioeconomic status, and ethnic enclave on mortality among Chinese, Japanese, …
Hidden Breast Cancer Disparities in Asian Women: Disaggregating Incidence Rates by Ethnicity and Migrant Status
Objectives. We estimated trends in breast cancer incidence rates for specific Asian populations in California to determine if disparities exist by immigrant status and age. Methods. To calculate rates by ethnicity and immigrant status, we obtained data for 1998 through 2004 cancer diagnoses from the California Cancer Registry and imputed immigrant status from Social Security Numbers for the 26% of cases with missing birthplace information. Popula…
Outdoor Falls Among Middle-Aged and Older Adults: A Neglected Public Health Problem
Objectives. Although risk factors for indoor falls among older individuals have been well studied, little is known about the etiology of outdoor falls. We examined risk factors for outdoor falls among middle-aged and older adults. Methods. We analyzed data on the most recent fall during the past year among participants aged 45 years and older in the control group (N=2193) of a case–control study of fractures. The study was conducted at 5 Northern…
