RESUMEN
INTRODUCTION: Sleep duration has been associated with dementia and stroke. Few studies have evaluated sleep pattern-related outcomes of brain disease in diverse Hispanics/Latinos. METHODS: The SOL-INCA (Study of Latinos-Investigation of Neurocognitive Aging) magnetic resonance imaging (MRI) study recruited diverse Hispanics/Latinos (35-85 years) who underwent neuroimaging. The main exposure was self-reported sleep duration. Our main outcomes were total and regional brain volumes. RESULTS: The final analytic sample included n = 2334 participants. Increased sleep was associated with smaller brain volume (ßtotal_brain = -0.05, p < 0.01) and consistently so in the 50+ subpopulation even after adjusting for mild cognitive impairment status. Sleeping >9 hours was associated with smaller gray (ßcombined_gray = -0.17, p < 0.05) and occipital matter volumes (ßoccipital_gray = -0.18, p < 0.05). DISCUSSION: We found that longer sleep duration was associated with lower total brain and gray matter volume among diverse Hispanics/Latinos across sex and background. These results reinforce the importance of sleep on brain aging in this understudied population. HIGHLIGHTS: Longer sleep was linked to smaller total brain and gray matter volumes. Longer sleep duration was linked to larger white matter hyperintensities (WMHs) and smaller hippocampal volume in an obstructive sleep apnea (OSA) risk group. These associations were consistent across sex and Hispanic/Latino heritage groups.

INTRODUCTION: Few studies have examined the associations of psychosocial factors with cognitive change in Hispanics/Latinos. METHODS: Data from the Hispanic Community Health Study/Study of Latinos-Investigation of Neurocognitive Aging (HCHS/SOL INCA) and Sociocultural studies were used (n = 2,155; ages ≥45 years). Psychosocial exposures included intrapersonal (ethnic identity, optimism, purpose in life), interpersonal (family cohesion, familism, social networks, social support), and social factors (ethnic discrimination, loneliness, subjective social status). Survey-linear regression models examined associations between psychosocial exposures and 7-year cognitive change (global cognition [GC], verbal learning, memory, word fluency [WF], and digit symbol substitution [DSS]). RESULTS: Familism predicted decline in GC, verbal learning, and memory; family cohesion predicted DSS decline; and loneliness predicted memory decline. Ethnic identity was protective against decline in GC and memory, optimism and social support were protective against decline in memory, and purpose in life was protective against WF decline. DISCUSSION: Psychosocial factors are differentially related to cognitive changes. Culturally relevant factors should be explored in Hispanic/Latino cognitive aging research. HIGHLIGHTS: Psychosocial factors are differentially related to cognitive changes in Latinos. Role of culturally relevant factors on cognition should be further explored. Familism predicted decline in global cognition, verbal learning, and memory. Ethnic identity predicted increase in global cognition and memory.

INTRODUCTION: Reproductive health history may contribute to cognitive aging and risk for Alzheimer's disease, but this is understudied among Hispanic/Latina women. METHODS: Participants included 2126 Hispanic/Latina postmenopausal women (44 to 75 years) from the Study of Latinos-Investigation of Neurocognitive Aging. Survey linear regressions separately modeled the associations between reproductive health measures (age at menarche, history of oral contraceptive use, number of pregnancies, number of live births, age at menopause, female hormone use at Visit 1, and reproductive span) with cognitive outcomes at Visit 2 (performance, 7-year change, and mild cognitive impairment [MCI] prevalence). RESULTS: Younger age at menarche, oral contraceptive use, lower pregnancies, lower live births, and older age at menopause were associated with better cognitive performance. Older age at menarche was protective against cognitive change. Hormone use was linked to lower MCI prevalence. DISCUSSION: Several aspects of reproductive health appear to impact cognitive aging among Hispanic/Latina women.

INTRODUCTION: We conducted admixture mapping and fine-mapping analyses to identify ancestry-of-origin loci influencing cognitive abilities. METHODS: We estimated the association of local ancestry intervals across the genome with five neurocognitive measures in 7140 diverse Hispanic and Latino adults (mean age 55 years). We prioritized genetic variants in associated loci and tested them for replication in four independent cohorts. RESULTS: We identified nine local ancestry-associated regions for the five neurocognitive measures. There was strong biological support for the observed associations to cognitive function at all loci and there was statistical evidence of independent replication at 4q12, 9p22.1, and 13q12.13. DISCUSSION: Our study identified multiple novel loci harboring genes implicated in cognitive functioning and dementia, and uncovered ancestry-relevant genetic variants. It adds to our understanding of the genetic architecture of cognitive function in Hispanic and Latino adults and demonstrates the power of admixture mapping to discover unique haplotypes influencing cognitive function, complementing genome-wide association studies. HIGHLIGHTS: We identified nine ancestry-of-origin chromosomal regions associated with five neurocognitive traits. In each associated region, we identified single nucleotide polymorphisms (SNPs) that explained, at least in part, the admixture signal and were tested for replication in independent samples of Black, non-Hispanic White, and Hispanic/Latino adults with the same or similar neurocognitive tests. Statistical evidence of independent replication of the prioritized SNPs was observed for three of the nine associations, at chr4q12, chr9p22.1, and chr13q12.13. At all loci, there was strong biological support for the observed associations to cognitive function and dementia, prioritizing genes such as KIT, implicated in autophagic clearance of neurotoxic proteins and on mast cell and microglial-mediated inflammation; SLC24A2, implicated in synaptic plasticity associated with learning and memory; and MTMR6, implicated in phosphoinositide lipids metabolism.
RESUMEN
OBJECTIVES: The Wealth Accumulation and Losses in Later life Early Cognitive Transitions (WALLET) study data was used to examine correlates with excess spending in older adults who do and do not have early memory loss. METHODS: The WALLET study collected detailed financial information from participants' primary checking account statements (n = 150). Information on participant sociodemographic, health, and disability status, memory functioning, financial decision-making, and financial literacy was also collected. Participants either had no memory problems or early memory loss. Bivariate and multiple regression analyses were conducted. RESULTS: The early memory loss group had significantly higher excess spending than those with no memory loss. Financial decision-making and higher-risk financial behaviors were also linked to higher excess spending. Early memory loss was no longer statistically significant after accounting for financial stressors and resources. CONCLUSIONS: The multidimensional nature of financial capacity assessment has long been known. The WALLET study data is unique, however, in that it demonstrates the links between excess spending with decision-making, early memory loss, and a set of specific financial behaviors. CLINICAL IMPLICATIONS: Real-world assessments of financial management and financial decision-making yield important information about how older adults are managing money and making key financial decisions. Checking account reviews can be used to determine excess spending.
RESUMEN
OBJECTIVE: Neuropsychological assessment among U.S. Arabic-speaking older adults is virtually non-existent due to lack of translated measures and normative data, as well as researchers' limited access to Middle Eastern/Arab Americans. The Montreal Cognitive Assessment (MoCA) is the only validated, widely-used dementia screen with Arabic language norms/cutoffs, yet, Arabic MoCA translations vary across countries and studies. We examined utility of a modified translation among Arabic-speaking immigrants in metro-Detroit. METHODS: The Arabic MoCA was modified to reflect consistency with the original English version while remaining meaningful in the Arabic language. The MoCA was then administered to 32 Arabic-speaking adults age 65 + living in metro-Detroit. Eight (25%) had an Alzheimer's disease or related dementia (ADRD) diagnosis. Each item was standardized and Cronbach's alpha assessed reliability. Ordinary least squares models examined whether an ADRD diagnosis predicts the total MoCA score and each item, adjusting for demographics. RESULTS: The mean age of the sample was 73 years old. The alpha was acceptably high at 0.87. Bivariate analyses show those with ADRD diagnosis scored lower overall on the MoCA. However, probability of diagnosis and age were confounded in the sample such that in multivariate analyses ADRD diagnosis did not explain additional variation beyond what is explained by age. Orientation, cube-copy test and serial 7s best distinguished those with ADRD. CONCLUSION: The modified Arabic language MoCA shows promise distinguishing those with an ADRD diagnosis. This translation provides a resource for neuropsychologists looking for translated tests when working with Arabic-speaking patients in the U.S.
RESUMEN
OBJECTIVE: This study examined education, partnership status, and the moderating role of the lockdown period on social connectedness during the COVID-19 pandemic in a sample of urban African-American older adults. METHODS: Five hundred thirty-four African-American adults living in Detroit (91.0% female, Mage = 74.53) reported demographic information pre-pandemic and answered one social connectedness questionnaire between April and December 2020. RESULTS: Participants interviewed after the lockdown (post-June 2020) reported more loneliness than those interviewed during the lockdown (April-June, 2020). Married/partnered participants reported less loneliness and social isolation. Loneliness did not differ between those with high education levels interviewed during the lockdown compared to post-lockdown. However, among individuals with low education levels, those interviewed after the lockdown reported more loneliness than those interviewed during the lockdown period. CONCLUSION: Our findings suggest partnership status is associated with more social connectedness during the pandemic and education accentuates the effects of forced isolation related to loneliness among urban African-American older adults.
RESUMEN
INTRODUCTION: We studied the replication and generalization of previously identified metabolites potentially associated with global cognitive function in multiple race/ethnicities and assessed the contribution of diet to these associations. METHODS: We tested metabolite-cognitive function associations in U.S.A. Hispanic/Latino adults (n = 2222) from the Community Health Study/ Study of Latinos (HCHS/SOL) and in European (n = 1365) and African (n = 478) Americans from the Atherosclerosis Risk In Communities (ARIC) Study. We applied Mendelian Randomization (MR) analyses to assess causal associations between the metabolites and cognitive function and between Mediterranean diet and cognitive function. RESULTS: Six metabolites were consistently associated with lower global cognitive function across all studies. Of these, four were sugar-related (e.g., ribitol). MR analyses provided weak evidence for a potential causal effect of ribitol on cognitive function and bi-directional effects of cognitive performance on diet. DISCUSSION: Several diet-related metabolites were associated with global cognitive function across studies with different race/ethnicities. HIGHLIGHTS: Metabolites associated with cognitive function in Puerto Rican adults were recently identified. We demonstrate the generalizability of these associations across diverse race/ethnicities. Most identified metabolites are related to sugars. Mendelian Randomization (MR) provides weak evidence for a causal effect of ribitol on cognitive function. Beta-cryptoxanthin and other metabolites highlight the importance of a healthy diet.

INTRODUCTION: Studies suggest bilingualism may delay behavioral manifestations of adverse cognitive aging including Alzheimer's dementia. METHODS: Three thousand nine hundred sixty-three participants (unweighted mean population age ≈56 years) at Hispanic Community Health Study/Study of Latinos baseline (2008-2011) self-reported their and their parents' birth outside the United States, Spanish as their first language, and used Spanish for baseline and comparable cognitive testing 7 years later (2015-2018). Spanish/English language proficiency and patterns of use were self-rated from 1 = only Spanish to 4 = English > Spanish. Cognitive testing included test-specific and global composite score(s) of verbal learning, memory, word fluency, and Digit Symbol Substitution (DSS). Survey linear regression models examined associations between baseline bilingualism scores and cognition. RESULTS: Higher second-language (English) proficiency and use were associated with higher global cognition, fluency, and DSS at follow-up and better than predicted change in fluency. DISCUSSION: The bilingual experience was more consistently related to 7-year level versus change in cognition for Hispanics/Latinos.
RESUMEN
INTRODUCTION: Despite increased risk of cognitive decline in Hispanics/Latinos, research on early risk markers of Alzheimer's disease in this group is lacking. Subjective cognitive decline (SCD) may be an early risk marker of pathological aging. We investigated associations of SCD with objective cognition among a diverse sample of Hispanics/Latinos living in the United States. METHODS: SCD was measured with the Everyday Cognition Short Form (ECog-12) and cognitive performance with a standardized battery in 6125 adults aged ≥ 50 years without mild cognitive impairment or dementia (xÌage = 63.2 years, 54.5% women). Regression models interrogated associations of SCD with objective global, memory, and executive function scores. RESULTS: Higher SCD was associated with lower objective global (B = -0.16, SE = 0.01), memory (B = -0.13, SE = 0.02), and executive (B = -0.13, SE = 0.02, p's < .001) function composite scores in fully adjusted models. DISCUSSION: Self-reported SCD, using the ECog-12, may be an indicator of concurrent objective cognition in diverse middle-aged and older community-dwelling Hispanics/Latinos.

OBJECTIVE: To study differences in screening adherence and follow-up after an abnormal Pap test in Non-Hispanic Black (Black) and Non-Hispanic White (White) women. METHODS: An observational cohort study using 2010 National Health Interview Survey cancer module to examine HPV knowledge, screening behavior, and follow-up to abnormal Pap test in Black and White women 18 years of age or older without a hysterectomy. We fit logistic regression models to examine associations between race and primary outcome variables including: HPV awareness, Pap test in the last three years, provider recommended Pap test, received Pap test results, had an abnormal Pap test, recommended follow-up, and adhered to the recommendation for follow-up. RESULTS: Analyzing data for 7509 women, Black women had lower odds ratios [OR] for: 1) HPV awareness (71% vs 83%; OR = 0.42; 95% CI = 0.36-0.49); 2) reporting Pap screening was recommended (59% vs 64%; OR = 0.76; 95% CI = 0.66-0.88), and 3) acknowledging receipt of Pap results (92% vs 94%; OR = 0.64; 95% CI = 0.49-0.83). Group differences persisted after covariates adjustment. In adjusted models, Black women had higher odds of reporting recent Pap screening (84% vs 77%; OR = 1.7; 95% CI = 1.42-2.03), but reported lower odds of receiving a follow-up recommendation subsequent to abnormal test (78% vs 87%; OR = 0.54; 95% CI = 0.31-0.95). CONCLUSION: Black women reported higher cervical cancer screening adherence but lower rates of being informed of an abnormal Pap test and contacted for follow-up treatment. We recommend a multilevel approach to deliver culturally appropriate education and communication for patients, physicians, clinicians in training, and clinic level ancillary staff.

Immigrants have lower and disproportionate use of preventive care. We use longitudinal panel data to examine how the 2014 full implementation of the ACA mandates affected change in preventive services (PS) use among immigrants that gained insurance. We used data on Foreign-Born (FB) and US-Born (USB) adults, ages 26-64 years, from the 2013/16 Medical Expenditures Panel Survey longitudinal files to examine within-person change in yearly utilization of age/sex specific United States Preventive Services Task Force (USPSTF) recommended services. We included five primary care (e.g., influenza immunization), three behavioral (e.g., diet), and seven cancer screening (e.g., mammography) measures. We used generalized estimating equations and difference-in-differences tests to assess the effects of insurance gain on: (1) change in PS utilization, and (2) reduction in utilization disparities between USB and FB adults, adjusting for predisposing, health enabling, and health needs factors. Our results showed that newly-insured FB adults substantially increased their use of all primary care checks, and exercise and diet advice. We also found improvements in use of endoscopies, two modalities of colon cancer screening, and prostate cancer screening, but not in receipt of mammography and clinical breast exams. Newly-insured FB PS use remained lower than use among continuously-insured USB adults, but some of the differences were explained by adjustment to enabling and health needs factors. Briefly, health insurance gains among immigrants translated into substantial improvements in use of recommended PS. Still, notable disparities persist among the newly-insured FB, and more so among the 1 in 5 that remain continuously uninsured.

INTRODUCTION: We aimed to determine whether obesity or metabolic syndrome (MetS) modify associations between sleep-disordered breathing (SDB), self-reported sleep duration (SD), and phenotypes of combined SDB/SD with 7-year neurocognitive decline (ND) in a community based-cohort of U.S. Hispanic/Latinos (N = 5500) in different age and sex groups. METHODS: The exposures were baseline SDB (respiratory event index ≥ 15), sleepiness (Epworth Sleepiness Scale ≥ 10), SD (< 6 hours, 6-9 hours, ≥ 9 hours). The outcome was 7-year ND. RESULTS: Mean age was 56.0 years, 54.8% were females. Obesity modified the association between SDB/SD and ND in memory (F = 21.49, P < 0.001) and global cognition (F = 9.14, P < 0.001) in the oldest age group. Women without MetS with combined long sleep/SDB exhibited most pronounced decline in global cognition (F = 3.07, P = 0.010). DISCUSSION: The association between combined SDB/long sleep and declines in memory and global cognition was most pronounced in obese older adults. Among women, MetS status modified the association between long sleep/SDB and decline in global cognition.

INTRODUCTION: We determined if actigraphy-derived sleep patterns led to 7-year cognitive decline in middle-aged to older Hispanic/Latino adults. METHODS: We examined 1035 adults, 45 to 64 years of age, from the Hispanic Community Health Study/Study of Latinos. Participants had repeated measures of cognitive function 7 years apart, home sleep apnea studies, and 1 week of actigraphy. Survey linear regression evaluated prospective associations between sleep and cognitive change, adjusting for main covariates. RESULTS: Longer sleep-onset latency was associated with declines in global cognitive function, verbal learning, and verbal memory. Longer sleep-onset latency was also cross-sectionally associated with verbal learning, verbal memory, and word fluency. Sleep fragmentation was not associated with cognitive change. CONCLUSION: In a cohort of mostly middle-aged Hispanic/Latinos, actigraphy-derived sleep-onset latency predicted 7-year cognitive change. These findings may serve as targets for sleep interventions of cognitive decline.

INTRODUCTION: Apolipoprotein E (APOE) alleles are associated with cognitive decline, mild cognitive impairment (MCI), and Alzheimer's disease in Whites, but have weaker and inconsistent effects reported in Latinos. We hypothesized that this heterogeneity is due to ancestry-specific genetic effects. METHODS: We investigated the associations of the APOE alleles with significant cognitive decline and MCI in 4183 Latinos, stratified by six Latino backgrounds, and explored whether the proportion of continental genetic ancestry (European, African, and Amerindian) modifies these associations. RESULTS: APOE ε4 was associated with an increased risk of significant cognitive decline (odds ratio [OR] = 1.15, P-value = 0.03), with the strongest association in Cubans (OR = 1.46, P-value = 0.007). APOE-ε2 was associated with decreased risk of MCI (OR = 0.37, P-value = 0.04) in Puerto Ricans. Amerindian genetic ancestry was found to protect from the risk conferred by APOE ε4 on significant cognitive decline. DISCUSSION: Results suggest that APOE alleles' effects on cognitive outcomes differ across six Latino backgrounds and are modified by continental genetic ancestry.

Since 2011, the Affordable Care Act (ACA) requires the provision of certain recommended clinical preventive services without cost-sharing for individuals in Medicare. We re-visited the effects of the ACA on preventive services utilization under Medicare, using data from the Medical Expenditure Panel Survey (MEPS) and examined the ACA's longer-term effects on preventive services utilization among Medicare beneficiaries. We analyzed nationally representative data on non-institutionalized Medicare beneficiaries (nâ¯=â¯27,124) from the 2006-2010 and 2012-2016 Medical Expenditure Panel Survey. Preventive services of interest were cholesterol test, blood pressure test, flu shot, endoscopy, blood stool test, clinical breast exam, mammography and prostate exam. We estimated propensity score weighted difference-in-difference (DID) models to test for differences in preventive services utilization based on Medicare insurance status. Nationwide, among beneficiaries with traditional Medicare only, who stood to gain the most from eliminating cost-sharing for preventive services, the percentage of women receiving clinical breast exams rose post-reform (Δâ¯=â¯8.1%; pâ¯<â¯0.015) as compared to Medicare beneficiaries with supplemental private coverage, while at the same time the percentage receiving other preventive services did not change post-reform (all pâ¯>â¯0.05). Based on this analysis of MEPS data spanning 2006-2016, the ACA's enhancement of Medicare coverage had only modest effects on the percentage of beneficiaries receiving a range of preventive services. Medicare beneficiaries should be better informed of the availability of these services and encouraged by their physicians to avail the no cost-sharing incentive of these reforms.

PURPOSE: To examine cross-sectional associations between perceived neighborhood environment and cognitive function among middle-aged and older Hispanic/Latino women and men. METHODS: Data from the Hispanic Community Health Study/Study of Latinos (2008-2011) and its Sociocultural Ancillary Study (2009-2010) were used. Participants were Hispanic/Latino women (n = 1812) and men (n = 1034) aged 45-74 years. Survey-weighted linear regression models were used to examine associations between self-reported perceived neighborhood environment (i.e., neighborhood social cohesion and problems categorized as quintiles, and neighborhood safety from crime categorized as low, medium, or high) with cognitive function (i.e., global cognition, verbal learning, memory, verbal fluency, and processing speed scores) in women and men. Final model adjusted for age, Hispanic/Latino background, language, field site, household income, education, years lived in neighborhood, and depressive symptoms. RESULTS: Women in the lowest quintile of perceived neighborhood problems (vs. highest quintile) had higher global cognition (ß 0.48, 95% CI 0.03, 0.94, p trend 0.229) and memory scores (0.60, 95% CI 0.11, 1.09, p trend: 0.060). Women in the highest quintile of perceived neighborhood social cohesion (vs. lowest quintile) had lower global cognition (ß - 0.56, 95% CI - 1.02, - 0.09, p trend 0.004), verbal learning (B - 1.01, 95% CI - 2.00, - 0.03, p trend 0.015), verbal fluency (B - 2.00, 95% CI - 3.83, - 0.16, p trend 0.006), and processing speed (B - 2.11, 95% CI - 3.87, - 0.36, p trend 0.009). There was no association between perceived neighborhood safety from crime and cognition among women, or between any perceived neighborhood environment measure and cognition among men. CONCLUSIONS: Middle-aged and older Hispanic/Latina women living in neighborhoods with the lowest perceived problems had higher global cognition and memory. Women living in neighborhoods with the highest perceived social cohesion had lower global cognition, verbal learning, verbal fluency, and processing speed.

BACKGROUND: Patient-centered healthcare in the context of a medical home (PCMH) is an important pathway to reducing healthcare inequities. To date, no work has examined the prevalence of care experiences associated with PCMH among non-elderly Black males. METHODS: We analyzed data, on 22 indicators representative of six healthcare domains associated with PCMH experiences, from non-Latino White (NLW) and Black males aged 18-64 from the 2008-2016 Medical Expenditure Panel Survey (n = 47,405). We used generalized linear models to test whether Behavioral Model factors attenuate any differences in access to these domains between NLW and Black males, and decomposition techniques to examine the contribution of these factors to reported differences. RESULTS: Black males reported 1) lower access to personal primary care providers, 2) poorer quality communication with providers, and 3) lower levels of care comprehensiveness (all p < 0.05). Differences between groups were attenuated but not eliminated by accounting for the Behavioral Model factors particularly through enabling and predisposing factors. Group health characteristics were not a primary driver of racial differences in care experiences across all the considered domains. CONCLUSIONS: Black men, in the U.S, continue to face barriers to accessing high quality, patient-centered care, specifically as it relates to accessing specialty care, medical tests, and patient-provider communication.

INTRODUCTION: To determine if sleep-disordered breathing (SDB), daytime sleepiness, insomnia, and sleep duration predict seven-year neurocognitive decline in US Hispanics/Latinos (N = 5247). METHODS: The exposures were baseline SDB, daytime sleepiness, insomnia, and sleep duration. The outcomes were change in episodic learning and memory (B-SEVLT-Sum and SEVLT-Recall), language (word fluency [WF]), processing speed (Digit Symbol Substitution), and a cognitive impairment screener (Six-item Screener [SIS]). RESULTS: Mean age was 63 ± 8 years, with 55% of the population being female with 7.0% Central American, 24.5% Cuban, 9.3% Dominican, 35.9% Mexican, 14.4% Puerto Rican, and 5.1% South American background. Long sleep (>9 hours), but not short sleep (<6 hours), was associated with decline (standard deviation units) in episodic learning and memory (ßSEVLT-Sum= -0.22 [se = 0.06]; P < .001; ßSEVLT-Recall = -0.13 [se = 0.06]; P < .05), WF (Pwf = -0.20 [se 5 0.06]; P < .01), and SIS (ßSIS = -0.16 [se = 0.06]; P < .01), but not processing speed, after adjusting for covariates. SDB, sleepiness, and insomnia were not associated with neurocognitive decline. CONCLUSION: Long sleep duration predicted seven-year cognitive decline.

BACKGROUND: Targeting habit-development (behavioral automaticity) as part of healthy lifestyle behavior change interventions may improve the adoption and maintenance of healthful behaviors. Few studies, however, have evaluated the feasibility of using a habit-development approach to foster the adoption of recommended physical activity and dietary behaviors. We report quantitative and qualitative data from a feasibility study evaluating a habit-formation intervention to foster healthy dietary and physical activity habits among middle aged African Americans with metabolic syndrome. METHODS: Using a non-comparative design we evaluated the feasibility an 8-week, hybrid format (telecoaching and face-to-face sessions), habit-focused intervention targeting the development of healthful dietary and physical activity habit development among 24 African Americans aged 40 and older with metabolic syndrome recruited from the emergency department - a setting where individuals in under-resourced communities often go for primary care. We administered behavioral automaticity measures tailored to participants' self-selected habits biweekly during the intervention and collected clinical outcomes of systolic blood pressure, weight, waist circumference, and BMI at baseline week 20. RESULTS: Participant attrition from the program was high (~ 50%). Despite high levels of attrition, 92% of intervention completers were extremely satisfied with the program. Intervention completers also experienced gains in behavioral automaticity for both dietary and physical activity habits. Overall, higher levels of adherence were associated with higher positive gains in automaticity with the statistical significance of the associations being more pronounced for physical activity habit plans relative to dietary habit plans. CONCLUSIONS: Our preliminary data support a habit-development approach for fostering the adoption of healthful dietary and physical activity habits. However, in this pilot study high rates of attrition were seen, suggesting that strategies to improve retention and participant engagement should be included in future studies, particularly when targeting African American emergency department patients.
