Patient Preferences for Lifestyle Management in a Multi-site Randomized Lifestyle Trial for Remission of the Metabolic Syndrome.

BACKGROUND: Randomized behavioral clinical trials are the gold standard for evaluating efficacy of a behavioral treatment. However, because participants are generally unblinded to treatment, preference for a specific treatment option can lead to biased results and/or reduced treatment efficacy. The purpose was to describe the relative frequency and correlates of existence of a preference and patient preference for either an in-person group-based or a remote self-directed, lifestyle treatment prior to randomization to one of these treatments. METHODS: The Enhanced Lifestyles for Metabolic Syndrome (ELM) trial is a multi-site behavioral clinical trial that compares efficacy of a group-based vs. a self-directed approach to lifestyle change on 2-year remission of the metabolic syndrome. Prior to randomization, participants were asked whether they had a preference for a particular treatment and, if so, which approach they preferred. Baseline data were used for a series of logistic regression models to determine behavioral correlates of treatment preference, independent of socioeconomic factors. RESULTS: Of the 331 participants, 131 (39.6%) had no preference for either treatment. Among the 200 with a preference, 56 (28.0%) preferred the self-directed program. Strength of a pre-existing habit of eating vegetables on most days was an independent correlate of no preference (adjusted OR, 1.27; 95% CI, 1.01-1.61; p = 0.03) and preference for a self-directed program (adjusted OR, 1.55; 95% CI, 1.09-2.22; p = 0.01). CONCLUSION: A pre-existing habit of eating vegetables was associated with no preference and preference for a less intensive lifestyle treatment. Post-treatment follow-up of the trial results will determine if concordance between preference and treatment assignment influences outcomes.

Prognostic significance of ischemic electrocardiographic changes with regadenoson stress myocardial perfusion imaging.

BACKGROUND: In patients undergoing regadenoson SPECT myocardial perfusion imaging (MPI), the prognostic value of ischemic ST-segment depression (ST↓) and the optimal ST↓ threshold have not been studied. METHODS: A retrospective cohort study of consecutive patients referred for regadenoson stress MPI was conducted. Patients with uninterpretable ECG were excluded. Two diagnostic thresholds of horizontal or downsloping ST↓ were studied, ≥ 0.5 mm and ≥ 1.0 mm. The primary endpoint was the composite major adverse cardiac events (MACE) of cardiac death, myocardial infarction, or coronary revascularization. RESULTS: Among 8615 subjects (mean age 62 ± 13 years; 55% women), 89 (1.0%) had ST↓ ≥ 1.0 mm and 133 (1.5%) had ST↓ ≥ 0.5 mm. Regadenoson-induced ST↓ was more common in women (P < .001). Mean follow-up was 2.5 ± 2.2 years. After multivariate adjustment, ST↓ ≥ 1.0 mm was associated with a non-significant increase in MACE risk (P = .069), irrespective to whether MPI was abnormal (P = .162) or normal (P = .214). Ischemic ST↓ ≥ 0.5 mm was independently associated with MACE in the entire cohort (HR 2.14; CI 1.38-3.32; P = .001), whether MPI is normal (HR 2.07; CI 1.07-4.04; P = .032) or abnormal (HR 2.24; CI 1.23-4.00; P = .007), after adjusting for clinical and imaging covariates. An ST↓ threshold of ≥ 0.5 mm provided greater incremental prognostic value beyond clinical and imaging parameters (Δχ2 = 12.78; P < .001) than ≥ 1.0 mm threshold (Δχ2 = 3.72; P = .093). CONCLUSION: Regadenoson-induced ischemic ST↓ is more common in women and it provides a modest independent prognostic value beyond MPI and clinical parameters. ST↓ ≥ 0.5 mm is a better threshold than ≥ 1.0 mm to define ECG evidence for regadenoson-induced myocardial ischemia.

Body mass index versus bioelectrical impedance analysis for classifying physical function impairment in a racially diverse cohort of midlife women: the Study of Women's Health Across the Nation (SWAN).

BACKGROUND: Body composition strongly influences physical function in older adults. Bioelectrical impedance analysis (BIA) differentiates fat mass from skeletal muscle mass, and may be more useful than body mass index (BMI) for classifying women on their likelihood of physical function impairment. AIMS: This study tested whether BIA-derived estimates of percentage body fat (%BF) and height-normalized skeletal muscle mass (skeletal muscle mass index; SMI) enhance classification of physical function impairment relative to BMI. METHOD: Black, White, Chinese, and Japanese midlife women (N = 1482) in the Study of Women's Health Across the Nation (SWAN) completed performance-based measures of physical function. BMI (kg/m2) was calculated. %BF and SMI were derived through BIA. Receiver-operating characteristic (ROC) curve analysis, conducted in the overall sample and stratified by racial group, evaluated optimal cutpoints of BMI, %BF, and SMI for classifying women on moderate-severe physical function impairment. RESULTS: In the overall sample, a BMI cutpoint of ≥ 30.1 kg/m2 correctly classified 71.1% of women on physical function impairment, and optimal cutpoints for %BF (≥ 43.4%) and SMI (≥ 8.1 kg/m2) correctly classified 69% and 62% of women, respectively. SMI did not meaningfully enhanced classification relative to BMI (change in area under the ROC curve = 0.002; net reclassification improvement = 0.021; integrated discrimination improvement = - 0.003). Optimal cutpoints for BMI, %BF, and SMI varied substantially across race. Among Black women, a %BF cutpoint of 43.9% performed somewhat better than BMI (change in area under the ROC curve = 0.017; sensitivity = 0.69, specificity = 0.64). CONCLUSION: Some race-specific BMI and %BF cutpoints have moderate utility for identifying impaired physical function among midlife women.

Associations of Psychological Well-Being With Carotid Intima Media Thickness in African American and White Middle-Aged Women.

OBJECTIVES: The present cross-sectional study aimed to a) examine associations between measures of psychological well-being, specifically life satisfaction and life engagement, and intima media thickness, a subclinical marker of atherosclerosis; b) investigate if the interaction of psychological well-being and life events correlated with intima media thickness; and c) explore these relationships across race. METHODS: A sample of 485 women (38% African American and 62% white; mean [standard deviation] age = 50.2 [2.9] years) underwent ultrasonography to assess carotid artery intima media thickness (IMT). The women completed self-report measures of life satisfaction, life engagement, and life events. RESULTS: Average (standard deviation) IMT was 0.666 (0.10) mm. Life satisfaction showed a significant, independent, inverse relationship with IMT, after controlling for demographic, behavioral, psychological, and cardiovascular covariates (ß = -0.105, p = .039), such that each 1-point higher life satisfaction score was correlated with a significant 0.008-mm lower level of mean IMT. No significant association was seen between life events and IMT (r = 0.05, p = .32), and life satisfaction did not interact with life events on IMT (ß = -0.036, p = .46). No significant interaction between life satisfaction and race on IMT was observed (ß = 0.068, p = .37). In contrast to life satisfaction, life engagement was not a significant correlate of IMT (r = -0.07, p = .12). CONCLUSIONS: Life satisfaction, a measure of psychological well-being, is an important independent correlate of subclinical atherosclerosis in middle-aged women.

Addressing asthma and obesity in children with community health workers: proof-of-concept intervention development.

BACKGROUND: The objective of this study was to design and test the feasibility and impact of a community health worker (CHW) intervention for comorbid asthma and obesity. METHODS: Using a proof of concept study design, we collected pre/post outcomes from a single intervention cohort of urban low-income in a single community area. A community-based participatory research approach was employed. Forty-six children and their caregivers were recruited. Children were 5-12 years old with physician-diagnosed asthma and body mass index (BMI) > 85%. Families were offered 12 home visits from CHWs that integrated asthma and obesity core curriculums. The primary asthma outcome was asthma control, measured via the Childhood Asthma Control Test (cACT). The primary obesity outcome was child body mass index (BMI). RESULTS: Families received a median of 10 out of the 12 home visits over 1 year. At 1 year, there was a significant improvement in the number of children with controlled asthma as measured via cACT (85.7% at 1 year compared to 61.9% at baseline, p = 0.01). Activity limitations and emergency utilization were reduced while inhaler technique improved (p < 0.01 for all). Child BMI z-score was reduced: mean = 1.97 (SD 0.79) at 1 year compared to mean = 2.13 (SD 0.40) at baseline, p < 0.01. No association was seen between change in child BMI and change in asthma control. Worse baseline child depression scores were associated with less improvement in asthma control (p = 0.003) and higher baseline caregiver post-traumatic stress disorder scores were associated with increased child BMI (p = 0.012). CONCLUSIONS: The CHW intervention has promise for improving asthma and weight outcomes in high-risk children with comorbid asthma and obesity; this model warrants further development and investigation.

Results from a community-based trial testing a community health worker asthma intervention in Puerto Rican youth in Chicago.

UNLABELLED: Abstract Objective: Puerto Rican children suffer disproportionately from asthma. Project CURA tested the efficacy of a community health worker (CHW) intervention to improve use of inhaled corticosteroids (ICS) and reduce home asthma triggers in Puerto Rican youth in Chicago. METHODS: This study employed a behavioral randomized controlled trial design with a community-based participatory research approach. Medications and technique were visually assessed; adherence was determined using dose counters. Home triggers were assessed via self-report, visual inspection and salivary cotinine. All participants received education on core asthma topics and self-management skills. Participants in the CHW arm were offered home education by the CHW in four visits over four months. The attention control arm received four newsletters covering the same topics. RESULTS: While most of the participants had uncontrolled persistent asthma, <50% had ICS at baseline. In the CHW arms, 67% of participants received the full four-visit intervention. In the Elementary school cohort (n=51), the CHW arm had lower odds of having an ICS (OR=0.2; p=0.02) at 12-months; no differences were seen in other outcomes between arms at any time point. The only significant treatment arm difference in the high school cohort (n=50) was in inhaler technique where the CHW arm performed 18.0% more steps correct at five months (p<0.01) and 14.2% more steps correct at 12 months (p<0.01). CONCLUSIONS: While this CHW intervention did not increase the number of participants with ICS or reduce home asthma triggers, important lessons were learned including challenges to CHW intervention fidelity and the need for CHWs to partner with clinical providers.

Body image satisfaction and depression in midlife women: the Study of Women's Health Across the Nation (SWAN).

With aging, women's bodies undergo changes that can affect body image perception, yet little is known about body image in midlife. The purpose of this study was to examine associations between body image and depressive symptoms in Caucasian and African-American midlife women from the Study of Women's Health Across the Nation (SWAN) Chicago site. Body image was measured using the Stunkard Adult Female Figure Rating Scale, and a clinically significant level of depressive symptoms was defined as Center for Epidemiologic Studies Depression Scale (CES-D) score of ≥16 (N=405; N=63 (15.6%) with clinically significant levels of depressive symptoms). Differences between perceived actual, perceived ideal, and actual body size and responses to questions concerning weight satisfaction and attractiveness were examined using logistic regression for associations with a CES-D score of ≥16. Women with body image dissatisfaction (odds ratio (OR)=1.91; p=0.04) or who perceived themselves as "unattractive" (OR=7.74; p<0.01) had higher odds of CES-D of ≥16. We found no significant difference by race. Our results were not confounded by BMI. These results suggest that midlife women with poor body image may be more likely to have clinically significant levels of depressive symptoms. Larger prospective studies are needed to better understand this association.

Correlates of 15-year maintenance of physical activity in middle-aged women.

BACKGROUND: Interventions to increase sustained physical activity are needed and should be based on proven theories. PURPOSE: To gain a better understanding of the correlates of sustained physical activity in midlife women, we used longitudinal epidemiologic data to investigate links between sustained physical activity and constructs advocated by three basic behavioral and social science theories: (1) self-determination, (2) social cognitive, and (3) social networks. A random sample of 90 midlife women, stratified by level of physical activity over 15 years, was selected from the Chicago cohort of the Longitudinal Study of Women's Health Across the Nation (SWAN). METHODS: Using data on self-reported physical activity collected over 15 years, women were categorized into consistently active, sporadically active, and sedentary. New data were collected on theory-relevant constructs, i.e., autonomous motivation (assessed by the Treatment Self-Regulation Questionnaire) and self-efficacy (assessed by the Self-Efficacy and Exercise Habits Survey). Every SWAN woman identified a close female friend who also completed the physical activity questionnaire. RESULTS: SWAN women with higher autonomous motivation (p = 0.002) and higher self-efficacy (p < 0.001) were more likely to be consistently physically active in analyses adjusted for age, race, and socioeconomic status. Sixty-one percent of SWAN women with a history of consistent physical activity had a friend who is currently highly active, versus 38 and 23 % for sporadically active and sedentary women, respectively (test for trend p = 0.008). CONCLUSION: In midlife women, constructs advocated by basic behavioral and social science theories were consistent with long-term patterns of physical activity behavior. Special focus should be given to these basic theories in the design of interventions to promote sustained physical activity in mid-life women.

Childhood Sexual Abuse and Pelvic Floor Dysfunction in Midlife Women in the Study of Women's Health Across the Nation.

Objectives: Research has shown a link between childhood sexual abuse (CSA) and lower urinary tract and sexual disorders in clinical settings. We examined whether CSA was associated with two specific aspects of high tone, elevated resting tension pelvic floor dysfunction (PFD) in community-dwelling women. Materials and Methods: Data were from 2068 participants (25.5% Black, 9.6% Chinese, 10.8% Japanese, 5.0% Hispanic, and 49.1% Non-Hispanic White) in the Study of Women's Health Across the Nation (SWAN), a multirace/multiethnic longitudinal observational study of women's midlife health. At baseline, enrolled women were 42-52 years old and premenopausal or early perimenopausal. Annual or biennial assessments conducted over 20 years (1996 through 2017) included single-item queries about urgency urinary incontinence and pain with sexual activity used to assess PFD outcomes. The 12th follow-up visit conducted in 2009-2011 assessed the primary exposure, history of CSA, using a single-item response. Multivariate logistic regression models tested study objectives. Results: The prevalence of CSA was 15%, self-reported in 313/2068 women. CSA and PFD, both pain with sexual activity (odds ratio [OR] = 1.56 confidence interval [95% CI = 1.12-2.18]) and urgency urinary incontinence (OR = 1.87 [95% CI = 1.29-2.71]), were significantly associated in unadjusted models. The final adjusted model that included sociodemographic variables and physical and behavioral risk factors was significant for pain with sexual activity (OR = 1.48 [95% CI = 1.08-2.02]), but not for urgency urinary incontinence (OR = 1.38 [95% CI = 0.96-1.98]). Conclusions: In midlife women, pain with sex, but not urgency urinary incontinence, was associated with a history of CSA. A multidisciplinary diagnostic and therapeutic approach to PFD is key, inclusive of CSA screening.

Pre- and Early Peri-menopausal Physical Function and Risk of Cardiovascular Events: The Study of Women's Health Across the Nation.

OBJECTIVES: To determine whether physical function (PF) before menopause is related to cardiovascular disease (CVD) risk. METHODS: Participants were N = 2950 pre-/early peri-menopausal women (median age 46, (25th-75th percentile: 43-48 years). Physical function was assessed at baseline using the Physical Function subscale of the SF-36 and scores were trichotomized (no, some, or substantial limitations). Clinical CVD events were ascertained at annual/biennial clinical assessments through the 15th follow-up visit. Risk of CVD was determined with Cox proportional hazards models. Results: Women were followed for a median of 19.1 years, during which 220 women had a CVD event. In fully adjusted models, women with substantial limitations at baseline had higher CVD risk compared to women with no limitations (hazards ratio [HR] = 1.55, 95% confidence interval [CI]: 1.12-2.33). Discussion: Substantial PF limitations in pre- and early peri-menopausal women are associated with higher risk of clinical CVD events, consistent with literature in older adults.

How well does the body adiposity index capture adiposity change in midlife women?: The SWAN fat patterning study.

OBJECTIVES: The body adiposity index (BAI) is a proposed alternative to the body mass index (BMI) that has shown good cross-sectional agreement with percent body fat (%BF) in validation studies. The objective of this study was to examine the ability of BAI to track adiposity change over time in a biracial sample of midlife women. METHODS: African-American (n = 159) and Caucasian (n = 206) women, aged 42-60 years, at the Chicago site of the Study of Women's Health Across the Nation were followed from 2002 to 2008. BAI and BMI were calculated from measurements taken at annual assessments. %BF was quantified using whole-body dual-energy X-ray absorptiometry. Difference scores (BAI(Δ) , BMI(Δ) , and %BF(Δ) ) quantified adiposity change over a mean of 1.6 (SD = 0.7) years. Lin's concordance correlation (ρ(c) ) and Bland-Altman limits-of-agreement assessed agreement between BAI and %BF. RESULTS: In examining adiposity change, BAI(Δ) showed poor agreement with %BF(Δ) in the overall sample (ρ(c) = 0.41), African-American women (ρ(c) = 0.36), and Caucasian women (ρ(c) = 0.43). BAI(Δ) estimated %BF(Δ) with minimal bias (+0.4%) but low precision (±6.3%BF limits-of-agreement). %BF(Δ) had weaker correlations with BAI(Δ) (rs = 0.38-0.48) than with BMI(Δ) (rs = 0.48-0.59). BAI and BMI showed similar cross-sectional associations with %BF in the overall sample and within each race (rs > 0.74). CONCLUSIONS: We conclude that BAI is less accurate than BMI in tracking adiposity change in midlife women, and would not be a suitable replacement for BMI in most research applications involving adiposity change.

Longitudinal associations of mid-life employment status with impaired physical function in the Study of Women's Health Across the Nation.

PURPOSE: This study examined whether employment status during mid-life and older adulthood is associated with physical function impairment. METHODS: Participants were 2700 women in the multiracial/multiethnic Study of Women's Health Across the Nation. Time-varying, lagged, and cumulative exposure analyses modeled associations between self-reported employment status and the likelihood of severe physical function impairment across 19 years of follow-up. RESULTS: Independent of demographic variables, women who were not working (OR = 1.58, 95% CI = 1.22, 2.04) or employed part-time (OR = 1.29, 95% CI = 1.04, 1.61) were more likely to report severe physical function impairments than women employed full-time. This same pattern was seen in lagged analyses predicting risk of physical function impairment from employment status at the prior assessment (not working vs. full-time: OR = 1.53, 95% CI = 1.08, 2.18; part-time vs. full-time: OR = 1.53, 95% CI = 1.17, 2.00). The likelihood of severe physical function impairment increased by 20% for every additional 10% of follow-up spent not working (OR = 1.02, 95% CI: 1.01, 1.03). Associations were robust to adjustment for health-related variables, body mass index, and physical activity. CONCLUSIONS: Women with lower levels of employment from mid-life to older adulthood were more likely to experience severe impairment in physical function. However, the underlying mechanisms, and the timescales over which associations unfold, require further study.

Contribution of common chronic conditions to midlife physical function decline: The Study of Women's Health Across the Nation.

BACKGROUND: Chronic conditions are associated with worse physical function and commonly develop during midlife. We tested whether the presence of 8 chronic conditions, or the development of these conditions, is associated with declines in physical function among midlife women as they transition into early late life. METHODS: Participants (N = 2283) were from the Study of Women's Health Across the Nation. Physical function was assessed at 8 visits starting at the study's fourth clinic visit in 2000/2001 through follow-up visit 15 (2015/2017) using the Short Form-36 Physical Function subscale. Chronic conditions included diabetes, hypertension, osteoarthritis, osteoporosis, stroke, heart disease, cancer, and depressive symptoms. Repeated-measures Poisson regression modeled associations between 1) prevalent chronic conditions at analytic baseline (visit 4) and longitudinal physical function, and 2) change in physical function associated with developing a new condition. Models were adjusted with the total number of other chronic conditions at visit 4. RESULTS: In separate fully-adjusted longitudinal models, prevalent heart disease and osteoporosis were associated with 18% (IRR = 0.815, 95% confidence interval [CI]: 0.755-0.876) and 12% (IRR = 0.876, 95% CI: 0.825-0.927) worse initial physical function, respectively. Prevalent osteoarthritis was associated with approximately 6% (IRR = 0.936, 95% CI: 0.913-0.958) worse initial physical function, and a slight additional worsening over time (IRR = 0.995, 95% CI: 0.994-0.996). A 12% (IRR = 0.878, 95% CI: 0.813-0.950) decrease in physical function concurrent with stroke development was evident, as was accelerated decline in physical function concurrent with heart disease development (IRR = 0.991, 95% CI: 0.988-0.995). CONCLUSIONS: Initial prevalent conditions related to the musculoskeletal system were associated with worse initial physical function, with some evidence of accelerated decline in physical function with osteoarthritis. Stroke and heart disease are less common than osteoarthritis in this age group, but the severe effects of these conditions on physical function shows the need for a greater focus on cardiovascular health during midlife. Women who develop chronic conditions during midlife may be at particular risk for poor physical function as they age, warranting disability prevention efforts focused on this population.

Impact of Chronic Medical Condition Development on Longitudinal Physical Function from Mid- to Early Late-Life: The Study of Women's Health Across the Nation.

BACKGROUND: Chronic medical conditions (CMCs) often emerge and accumulate during the transition from mid- to late-life, and the resulting multimorbidity can greatly impact physical function. We assessed the association of CMC presence and incidence on trajectories of physical function from mid- to early late-life in the Study of Women's Health Across the Nation. METHODS: Physical function was assessed at eight clinic visits (average 14 years follow-up) using the physical function subscale of the Short Form-36. CMCs included osteoarthritis, diabetes, stroke, hypertension, heart disease, cancer, osteoporosis, and depressive symptomatology, and were considered cumulatively. Repeated-measures Poisson models estimated longitudinal change (expressed as percent difference) in physical function by chronic CMCs. Change-points assessed physical function change coincident with the development of a new condition. RESULTS: Women (N = 2,283) followed from age 50.0 ± 2.7 to 64.0 ± 3.7 years; 7.3% had zero CMCs through follow-up, 22.5% (N = 513) had no baseline CMCs but developed ≥1, 22.7% women had ≥1 baseline CMC but never developed another, and 47.6% had ≥1 baseline CMC and developed ≥1 more. Each additional baseline CMC was associated with 4.0% worse baseline physical function and annual decline of 0.20%/year. Women with more baseline CMCs had greater decline in physical function with a new CMC (-1.90% per condition); and annual decline when developing a new condition accelerated by -0.33%/year per condition. CONCLUSIONS: Self-reported physical function changes are evident from mid- to early late-life with the development of CMCs. Preventing or delaying CMCs may delay declines in physical function, and these potential pathways to disability warrant further research.

Depressive symptoms and increased visceral fat in middle-aged women.

OBJECTIVE: To examine whether depressive symptoms are differentially associated with visceral adipose tissue (VAT), which is more metabolically active and confers greater cardiovascular risk than subcutaneous fat (SAT). Prior research has shown an association between depression and central adiposity. Mechanisms underlying the association between depression and increased cardiovascular risk remain poorly understood. Central adiposity is one potential pathway. METHODS: We investigated the cross-sectional association between depressive symptoms, assessed by the Center for Epidemiological Studies Depression Scale (CES-D), and VAT and SAT, assessed by computed tomography, in a sample of 409 middle-aged women (44.7% African-Americans, 55.3% Whites; mean age = 50.4 years) participating in the Chicago site of the Study of Women's Health Across the Nation (SWAN). RESULTS: With adjustments for age, race, total percent fat, and sex hormone binding globulin (SHBG), each 1-point higher score on the CES-D was associated with 1.03-cm(2) greater VAT (p < .001). Women with a CES-D score of >or=16, indicative of clinically relevant depressive symptomatology, had 24.5% more VAT than women with lower CES-D scores (p < .001). Further adjustment for Framingham Risk Score and physical activity did not alter the findings, and associations did not vary by race. Associations were strongest in obese and overweight women. Depressive symptoms were unrelated to SAT. CONCLUSIONS: Increased visceral fat may be one pathway by which depression contributes to excess risk for cardiovascular disease and diabetes. Further research is needed to examine whether depressive symptoms influence accumulation of VAT over time.

Hostility is associated with visceral, but not subcutaneous, fat in middle-aged African American and white women.

OBJECTIVE: To examine the cross-sectional association between hostility and measures of abdominal fat (visceral, subcutaneous) in middle-aged African American and white women. Because fat-patterning characteristics are known to differ by race, we were particularly interested in examining whether these associations were similar for women of both racial/ethnic groups. METHODS: Participants were 418 (45% African American, 55% white) middle-aged women from the Chicago site of the Study of Women's Health Across the Nation. Visceral and subcutaneous fat were measured by computed tomographic scans and hostility was assessed via questionnaire. Multivariate linear regression models were conducted to test associations among race/ethnicity, hostility, and measures of abdominal fat. RESULTS: In models adjusted for race/ethnicity and total percent fat, higher levels of hostility were associated with a greater amount of visceral fat (B = 1.8, standard error = 0.69, p = .01). This association remained significant after further adjustments for education, and multiple coronary heart disease (CHD) risk factors. Hostility was not associated with subcutaneous fat (p = .8). Although there were significant racial/ethnic differences in hostility (p < .001) and the amount of total body (p < .001), subcutaneous (p < .001) and visceral fat (p < .001), the associations between hostility and measures of abdominal fat did not differ for African American compared with white women (race/ethnicity x hostility interaction, p = .67 for visceral, p = .85 for subcutaneous). CONCLUSIONS: Hostility may affect CHD risk in women via the accumulation of visceral fat. Despite significant black-white differences in fat patterning and overall CHD risk, the association between hostility and visceral fat seems to be similar for both African American and white women.

Development of a lifestyle intervention for the metabolic syndrome: Discovery through proof-of-concept.

OBJECTIVE: The aim was to describe the early phases of the progressive development of a lifestyle treatment for sustained remission of the metabolic syndrome (MetS) using the Obesity-Related Behavioral Intervention Trials (ORBIT) model for behavioral treatment development as a guide. METHODS: Early discovery and design phases produced a 3-component (diet, physical activity, stress), group-based lifestyle treatment with an intensive 6-month phase followed by monthly, participant-led maintenance meetings. In the proof-of-concept phase, 26 participants with the MetS (age 53 ± 7 years, 77% female, and 65% ethnic minority) were recruited in a quasi-experimental design to determine if treatment could achieve the prespecified benchmark of MetS remission in ≥50% at 2.5 years. Exploratory outcomes focused on MetS components, weight, and patient-centered benefits on energy/vitality and psychosocial status. RESULTS: MetS remission was achieved in 53.8% after a median of 2.5 years. At 2.5 years, an increase of +15.4% reported eating ≥3 servings of vegetables/day, +7.7% engaged in ≥150 minutes of moderate-to-vigorous physical activity/week; and +11.5% reported experiencing no depression in the past 2 weeks. Weight loss ≥5% was achieved by 38.5%, and energy/vitality, negative affect, and social support improved. Median group attendance over 2.5 years was 73.8%. CONCLUSIONS: It is plausible that this lifestyle program can produce a remission in the MetS, sustained through 2.5 years. After refinements to enhance precision and strength, progression to feasibility pilot testing and a randomized clinical trial will determine its efficacy as a cost-effective lifestyle option for managing the MetS in the current health care system.

What Really Happens in the Home: The Medication Environment of Urban, Minority Youth.

BACKGROUND: Asthma disproportionately affects minority youth. Understanding the home medication environment and its relation to medication adherence can shape interventions to improve health outcomes. OBJECTIVE: The objective of this study was to describe the asthma medication environment in the homes of urban minority youth and to determine predictors of medication use and technique in this population. METHODS: Baseline data from 2 cohorts of minority youth with asthma in Chicago were combined for cross-sectional analysis. Bilingual research assistants (RAs) collected data in the home. RAs asked caregivers and children to self-report medications using pictures and observed children's asthma medications and inhaler technique. RESULTS: The sample contained 175 mainly Latino youth (85.6%) ranging from 5 to 18 years old. Most were on public insurance (80%) and had uncontrolled asthma by self-report (89.7%). Only 27.4% had a spacer, 74.9% had a quick relief medicine, and 48.6% had any controller medicine. RA observations of controllers agreed with children (36%) and parental self-report (42.3%) but did not match the specific observed controllers. Children reported less parental help with medications (43%) than their parents (58.1%). One child was able to properly demonstrate 100% of the inhaler steps and 35.6% achieved >70% of inhaler steps. A better medication technique was associated with having a controller (b = 12.2, SE = 3.0, P < .0001), quick reliever (b = 8.05, SE = 3.5, P = .023), and a spacer (b = 9.3, SE = 3.54, P = .009). CONCLUSIONS: This rigorous evaluation of the home medication environment of high-risk youth demonstrated that many families lack critical medications, devices, and a technique for proper management of asthma.

Recruitment and Baseline Characteristics of Participants in the Lifestyle Improvement Through Food and Exercise (LIFE) Study.

African Americans experience poorer diabetes outcomes than non-Hispanic Whites. Few clinical trials of diabetes self-management interventions specifically target African Americans, perhaps due to well-documented barriers to recruitment in this population. This paper describes strategies used to successfully recruit 211 low-income African Americans from community clinics of a large, urban public hospital system to a randomized clinical trial of an 18-month diabetes self-management intervention. Diabetes-related physiological, psychosocial, and behavioral characteristics of the sample are reported. The sample was 77% female, mean age = 55, mean A1C = 8.5%, 39% low health literacy, 28.4% moderate/severe depression, and 48.3% low adherence. Participants ate a high-fat diet with low vegetable consumption. Relative to males, females had higher BMI, depression, and stress, and better glycemic control, less physical activity, and less alcohol consumption. Males consumed more daily calories, but females consumed a greater proportion of carbohydrates. Gender-specific diabetes self-management strategies may be warranted in this population.

Cynical hostility and carotid atherosclerosis in African American and white women: the Study of Women's Health Across the Nation (SWAN) Heart Study.

BACKGROUND: Hostility is associated with increased cardiovascular disease mortality and morbidity and may be related to subclinical atherosclerosis; less is known about this association among women and minority groups. METHODS: We examined the association between hostility and intimal-medial thickening (IMT) as well as presence/absence of plaque in the carotid arteries in middle-aged white and African American women. Hostility was measured by a 13-item questionnaire and IMT and plaque were assessed by B-mode ultrasonography in 589 participants from the Chicago and Pittsburgh sites of the SWAN. RESULTS: In age- and site-adjusted models, each 1-point increment in hostility score predicted a significant 0.0057-mm higher mean IMT (P < .0001) and 0.0081-mm higher maximum IMT (P < .0001)--effects that were identical in magnitude to each 1-year increment in age. Adjustments for race, education, body mass index, resting systolic blood pressure, and smoking diminished these associations, but they remained significant (P < or = .01). With hostility scores modeled in approximate tertiles, high scorers (> or = 6) had greater mean (P = .0005) and maximum (P = .0004) IMT than low scorers (0 or 1); moderate and low scorers did not differ (age-adjusted mean values for low, moderate, and high scorers were 0.657, 0.662, and 0.694 mm, respectively, for mean IMT; those for low, moderate, and high scorers were 0.855, 0.860, and 0.906 mm, respectively, for maximum IMT). Hostility was unrelated to presence of plaque and did not interact with race, education, smoking, and body mass index. CONCLUSIONS: Hostility is related to small but significantly greater subclinical atherosclerosis in middle-aged women; this association is not explained by traditional risk factors.
