Generating Health Estimates by Zip Code: A Semiparametric Small Area Estimation Approach Using the California Health Interview Survey
Objectives. We propose a method to meet challenges in generating health estimates for granular geographic areas in which the survey sample size is extremely small. Methods. Our generalized linear mixed model predicts health outcomes using both individual-level and neighborhood-level predictors. The model’s feature of nonparametric smoothing function on neighborhood-level variables better captures the association between neighborhood environment a…
Small Area Estimates Reveal High Cigarette Smoking Prevalence in Low-Income Cities of Los Angeles County
Outcomes of a Breast Health Project for Hmong Women and Men in California
Objectives. We used a community-based research approach to test a culturally based breast cancer screening program among low-income Hmong women in central and southern California. Methods. We designed a culturally informed educational program with measures at baseline and 1-year follow-up in 2 intervention cities and 1 comparison city. Measures included changes in breast cancer screening, knowledge, and attitudes. Results. Compared with women in …
Who is Using Emergency Contraception
Role of Health Insurance Coverage in Women’s Access to Prescription Medicines
Small-Area Estimation of Health Insurance Coverage for California Legislative Districts
Objectives. To aid state and local policymakers, program planners, and community advocates, we created estimates of the percentage of the population lacking health insurance in small geographic areas of California. Methods.Finally, calibration ensured the consistency and stability of the estimates when they were aggregated. Results. Health insurance coverage among nonelderly persons varied widely across assembly districts, from 10% to 44%. The ut…
Effects of Community Factors on Access to Ambulatory Care for Lower-Income Adults in Large Urban Communities
This study examines the effects of community-level and individual-level factors on access to ambulatory care for lower-income adults in 54 urban metropolitan statistical areas in the United States. Drawing on a conceptual behavioral and structural framework of access, the authors developed multivariate models for insured and uninsured lower-income adults to assess the adjusted effects of community- and individual-level factors on two indicators o…
A Comparison of Hispanic and White Adolescent Females' Use of Family Planning Services in California
Access to Medical Care for Low-Income Persons: How do Communities Make a Difference?
This paper considers the impact of community-level variables over and above the effects of individual characteristics on healthcare acess for low-income children and adults residing in large metropolitan statistical areas (MSAs). Further, we rank MSAs’ performance in promoting healthcare access for their low-income populations. The individual-level data come from the 1995 and 1996 National Health Interview Survey (NHIS). The community-level varia…
Perceptions of Health and Use of Ambulatory Care: Differences between Korean and White Elderly
This study identifies whether culturally based differences in perceptions of health resulted in differences in ambulatory care use among the elderly. Methods:The authors conducted stratified Poisson regressions on data from a 1992 survey of older Koreans and Whites in Los Angeles County. The models included measures of demographics, health, functioning, income, insurance, social support, and culture (perceptions of health or other beliefs). Resul…
