Improving the Validity of the Behavioral Risk Factor Surveillance System Alcohol Measures.

ABSTRACT:

Background

Valid measurement of alcohol use can be difficult in surveys, which are subject to biases like underreporting and differential nonresponse. Still, monitoring trends, policy impacts, disparities, and related issues all require valid individual- and state-level drinking data collected over time. Here, we propose a double-adjustment approach for improving the validity of the Behavioral Risk Factor Surveillance System (BRFSS) alcohol measures.

Methods

Validity analyses of the 1999 to 2016 BRFSS, a general population survey of U.S. adults. Measures are aggregated to state level for N = 918 observations, single-adjusted for BRFSS methodologic changes, and double-adjusted by per capita consumption. Fixed-effects models: (i) assess predictive validity using adjusted BRFSS drink volume to predict mortality outcomes and (ii) assess outcome validity using state-level alcohol taxes to predict adjusted BRFSS volume.

Results

Neither the raw nor the single-adjusted BRFSS drinking measures were related to mortality in the expected direction, while double-adjusted BRFSS volume and 5+ days were significantly positively related to mortality, as expected. Spirits and beer taxes were not related to single-adjusted BRFSS drinking in the expected direction. However, spirits and beer taxes were both significantly related to double-adjusted BRFSS volume in the expected directions.

Conclusions

Future studies should consider using the double-adjusted BRFSS measures to ensure the validity of drinking survey data in analyses where variation over time is considered.

Project description:INTRODUCTION:Adverse childhood experiences (ACEs) are negative life events occurring before the age of 18 y. ACEs are risk factors for heart disease and diabetes in adult life. Furthermore, individuals who experience ACEs are more likely to smoke and become obese-factors associated with poor oral health. OBJECTIVE:This study investigated likely associations between ACEs and the oral health measures of the 2010 Behavioral Risk Factor Surveillance System (BRFSS). METHODS:Data from 16,354 participants of the 2010 BRFSS were analyzed with SAS 9.4. ACE scores were calculated in 2 domains: abuse (emotional, physical, or sexual) and household challenges (parental separation or divorce, intimate partner violence, household substance abuse, household mental illness, and incarceration). ACE scores, ranging from 0 to 8, were categorized into 0, 1, 2, 3, and ≥4. The 2010 BRFSS oral health measures included >1 y since last dental visit, ≥6 teeth extracted, and ≥2 y since last dental cleaning. Survey logistic regression estimated prevalence odds ratios and 95% CIs, adjusted for age, sex, race/ethnicity, and educational attainment. RESULTS:The weighted mean ACE score was 1.74 (95% CI = 1.68 to 1.81), and the weighted and age-standardized percentages of study participants with ACE scores of 0, 1, 2, 3, and ≥4 were 33.1%, 24.3%, 14.9%, 9.69%, and 18.1%, respectively. There appeared to be a dose-response association between categories of ACE scores and the oral health measures. Specifically, when compared with participants with an ACE score of 0, participants with ACE scores of 1, 2, 3, and ≥4 had adjusted prevalence odds ratios (95% CIs) of 1.10 (0.82 to 1.47), 1.20 (0.90 to 1.60), 1.35 (0.98 to 1.85), and 1.72 (1.31 to 2.26), respectively, for reporting ≥2 y since last dental cleaning. CONCLUSIONS:Findings suggest that ACEs may be associated with poor oral health measures in adulthood, even after adjusting for important oral diseases risk factors. Longitudinal follow-up studies are needed to delineate pathways by which this relationship occurs. KNOWLEDGE TRANSFER STATEMENT:Our findings indicate that exposure to childhood trauma may have negative impacts on oral health in adulthood. Oral health practitioners need to be aware of the potential impacts of childhood trauma on health behaviors that ultimately affect oral health outcomes.

Project description:BackgroundDiabetes mellitus (DM) is a leading contributor to morbidity and mortality in the United States (US). Prior DM prevalence estimates in Asian Americans are predominantly from Asians aggregated into a single group, but the Asian American population is heterogenous.ObjectiveTo evaluate self-reported DM prevalence in disaggregated Asian American subgroups to inform targeted management and prevention.DesignSerial cross-sectional analysis.ParticipantsRespondents to the US Behavioral Risk Factor Surveillance System surveys who self-identify as non-Hispanic Asian American (NHA, N=57,001), comprising Asian Indian (N=11,089), Chinese (N=9458), Filipino (N=9339), Japanese (N=10,387), and Korean Americans (N=2843), compared to non-Hispanic White (NHW, N=2,143,729) and non-Hispanic Black (NHB, N=215,957) Americans.Main measuresPrevalence of self-reported DM. Univariate Satterthwaite-adjusted chi-square tests compared the differences in weighted DM prevalence by sociodemographic and health status.Key resultsSelf-reported fully adjusted DM prevalence was 8.7% (95% confidence interval 8.2-9.3) in NHA, compared to 14.3% (14.0-14.6) in NHB and 10.0% (10.0-10.1) in NHW (p<0.01 for difference). In NHA subgroups overall, DM prevalence was 14.4% (12.6-16.3) in Filipino, 13.4% (10.9-16.2) in Japanese, 10.7% (9.6-11.8) in Asian Indian, 5.1% (4.2-6.2) in Chinese, and 4.7% (3.4-6.3) in Korean Americans (p<0.01). Among those aged ≥65 years, DM prevalence was highest in Filipino (35.0% (29.4-41.2)) and Asian Indian (31.5% (25.9-37.8)) Americans. Adjusted for sex, education, and race/ethnicity-specific obesity category, NHA overall had a 21% higher DM prevalence compared to NHW (prevalence ratio 1.21 [1.14-1.27]), while prevalence ratios were 1.42 (1.24-1.63) in Filipinos and 1.29 (1.14-1.46) in Asian Indians.ConclusionsAdjusted self-reported DM prevalence is higher in NHA compared with NHW. Disaggregating NHA reveals heterogeneity in self-reported DM prevalence, highest in Filipino and Asian Indian Americans.

Project description:Importance:The prevalence of the use of electronic cigarettes (e-cigarettes) in the United States has grown rapidly since their introduction to the market more than a decade ago. While several studies have demonstrated an association between combustible cigarette smoking and depression, the association between e-cigarette use and depression has not been thoroughly studied. Objective:To examine the association between e-cigarette use and depression in a nationally representative sample of the adult population in the United States. Design, Setting, and Participants:Cross-sectional study of the Behavioral Risk Factor Surveillance System database, 2016 to 2017. The Behavioral Risk Factor Surveillance System is the largest national telephone-based survey of randomly sampled adults in the United States. A total of 892 394 participants with information on e-cigarette use and depression were included. Data analysis was conducted in May 2019. Exposures:Electronic cigarette use status defined by self-report as never, former, or current use. Main Outcomes and Measures:Self-reported history of a clinical diagnosis of depression. Results:Of the 892 394 participants (414 326 [29.0%] aged ≥60 years; 502 448 [51.3%] women), there were 28 736 (4.4%) current e-cigarette users, of whom 13 071 (62.1%) were aged between 18 and 39 years. Compared with never e-cigarette users, current e-cigarette users were more likely to be single, male, younger than 40 years, and current combustible cigarette smokers (single, 120 797 [24.3%] vs 10 517 [48.4%]; men, 318 970 [46.6%] vs 14 962 [60.1%]; aged 18-39 years, 129 085 [32.2%] vs 13 071 [62.1%]; current combustible cigarette use, 217 895 [7.9%] vs 8823 [51.8%]). In multivariable adjusted models, former e-cigarette users had 1.60-fold (95% CI, 1.54-1.67) higher odds of reporting a history of clinical diagnosis of depression than never users, whereas current e-cigarette users had 2.10 (95% CI, 1.98-2.23) times higher odds. Additionally, higher odds of reporting depression were observed with increased frequency of use among current e-cigarette users compared with never users (daily use: odds ratio, 2.39; 95% CI, 2.19-2.61; occasional use: odds ratio, 1.96; 95% CI, 1.82-2.10). Similar results were seen in subgroup analyses by sex, race/ethnicity, smoking status, and student status. Conclusions and Relevance:This study found a significant cross-sectional association between e-cigarette use and depression, which highlights the need for prospective studies analyzing the longitudinal risk of depression with e-cigarette use. If confirmed by other study designs, the potential mental health consequences may have regulatory implications for novel tobacco products.

Project description:Obesity is a well-established risk factor for cardiovascular disease (CVD), but the underweight population of body mass index (BMI) below 18.5 kg/m has not been an object of concern. The objective of this study is to investigate whether underweight could be an independent risk factor for CVD in a population-based cross-sectional study.Cross-sectional data of 2013 Behavioral Risk Factor Surveillance System (BRFSS) database encompassing 491,773 US adult subjects were used to assess risk for CVD. Primary outcomes were the incidence and relative risks (RRs) of CVD including stroke, heart attack/myocardial infarction, or coronary artery disease according to BMI category. All analyses used weighted sampling probabilities of data source.The underweight population had a 19.7% greater risk of CVD than did the normal-weight, and the overweight and obese population had a 50% and 96% increased risk, respectively. When adjusted with covariates, the relative risk for CVD elevated in underweight population (adjusted RR 1.34 [95% confidence interval (CI) 1.335-1.348]). Conversely, the adjusted relative risk was significantly attenuated in the obese group (adjusted RR 1.149 [95% CI 1.147-1.151]) and it was even insignificant in the overweight group (adjusted RR 1.00 [95% CI 1.000-1.003]). In subanalysis for each CVD category, being underweight among BMI status was the strongest independent risk factor for stroke (adjusted RR 1.441 [95% CI 1.431-1.450]), heart attack/ myocardial infarction (MI) (adjusted RR 1.23 [95% CI 1.217-1.233]), and angina/coronary artery disease (adjusted RR 1.20 [95% CI 1.189-1.206]). Especially among the population below 40-year old, relative risk estimates remained increased in the underweight population; persons who were underweight had a 2.3-fold greater adjusted relative risk of CVD as compared with those with normal weight when we stratified with age.Underweight below BMI 18.5 kg/m may be another risk factor for CVD, and CVD risk of the overweight and obese population largely depended on other comorbidities accompanied by obesity.
