OBJECTIVE Scanty and controversial information is available on the impact of macroeconomic fluctuations on smoking behaviour. No study has quantified the effects of fiscal crises on smoking prevalence. This study aimed to investigate the effects of the 2007-2008 economic crisis on smoking prevalence and number of smokers in the USA. METHODS Using data from the repeated Behavioural Risk Factor...

The prevalence of no leisure-time physical activity (LTPA) among U.S. residents decreased from 31% in 1989 to 25% in 2002 and was still at 25% in 2008, based on Behavioral Risk Factor Surveillance System (BRFSS) data. Further reduction in the prevalence of no LTPA among all adults might be hindered by population subgroups that have exceptionally high rates of no LTPA, such as adults with arthri...

CONTEXT Intimate partner violence (IPV) is a public health problem that affects people across the entire social spectrum. However, no previous population-based public health studies have examined the prevalence of IPV in rural areas of the United States. Research on IPV in rural areas is especially important given that there are relatively fewer resources available in rural areas for the preven...

Transgender persons are at high risk for human immunodeficiency virus (HIV) infection; in a recent analysis of the results of over nine million CDC funded HIV tests, transgender women* had the highest percentage of confirmed positive results (2.7%) of any gender category (1). Transgender men,† particularly those who have sex with cisgender§ men, are also at high risk for infection (2). HIV test...

BACKGROUND Existing evidence on stress and asthma prevalence has disproportionately focused on pregnancy and postpregnancy early life stressors, largely ignoring the role of childhood adversity as a risk factor. Childhood adversity (neglect, stressful living conditions and maltreatment) may influence asthma prevalence through mechanisms on the hypothalamic-pituitary axis. METHODS Data from th...

When investigating health disparities, it can be of interest to explore whether adjustment for socioeconomic factors at the neighborhood level can account for, or even reverse, an unadjusted difference. Recently, we proposed new methods to adjust the effect of an individual-level covariate for confounding by unmeasured neighborhood-level covariates using complex survey data and a generalization...

The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing State-based telephone survey of adults, administered through State health departments. The survey estimates health status and the prevalence of various risk factors among respondents, who include both fee-for-service and managed care Medicare beneficiaries. In this article the authors present an overview of the BRFSS and repor...

BACKGROUND The 2009 pandemic influenza A (H1N1) virus (2009 H1N1) was first identified in April 2009 and quickly spread around the world. The first doses of influenza A (H1N1) 2009 monovalent vaccine (2009 H1N1 vaccine) became available in the U.S. in early October 2009. Because people with asthma are at increased risk of complications from influenza, people with asthma were included among the ...

INTRODUCTION Beginning in 2013, in addition to the 2-item disability question set asked since 2001, Behavioral Risk Factor Surveillance System (BRFSS) began using 5 of the 6 items from the US Department of Health and Human Services-recommended disability question set. We assess and compare disability prevalence using the 2-question and 5-question sets and describe characteristics of respondents...

Public health researchers have used a class of statistical methods to calculate prevalence estimates for small geographic areas with few direct observations. Many researchers have used Behavioral Risk Factor Surveillance System (BRFSS) data as a basis for their models. The aims of this study were to 1) describe a new BRFSS small area estimation (SAE) method and 2) investigate the internal and e...
