COVID-19 Cases and Deaths in Skilled Nursing Facilities in Cook County, Illinois.

OBJECTIVE: The COVID-19 pandemic has had a devastating impact on older adults residing in skilled nursing facilities. This study examined the pathways through which community and facility factors may have affected COVID-19 cases and deaths in skilled nursing facilities. METHODS: We used structural equation modeling to examine the number of COVID-19 cases and deaths in skilled nursing facilities in Cook County, Illinois, from January 1 through September 30, 2020. We used data from the Centers for Medicare & Medicaid Services, the Illinois Department of Public Health, and the Cook County Medical Examiner's Office to determine the number of resident COVID-19 cases and deaths, number of staff cases, facility-level characteristics, and community-level factors. RESULTS: Poorer facility quality ratings and higher numbers of staff COVID-19 cases were associated with increased numbers of resident COVID-19 cases and deaths. For-profit ownership was associated with larger facilities and higher resident-to-staff ratios, which increased the number of staff COVID-19 cases. Furthermore, skilled nursing facilities with a greater percentage of White residents were in areas with lower levels of social vulnerability and were less likely to be for-profit and, thus, were associated with higher quality. CONCLUSIONS: For-profit ownership was associated with lower facility quality ratings and increases in the number of staff COVID-19 cases, leading to increased resident COVID-19 cases and deaths. Establishing enforceable regulations to ensure quality standards in for-profit skilled nursing facilities is critical to prevent future outbreaks and reduce health disparities in facilities serving racial and ethnic minority populations.

Association of diet quality and physical function among overweight and obese primarily African American older adults with lower extremity osteoarthritis.

BACKGROUND: Strategies to reduce osteoarthritis (OA) symptoms and increase physical function in persons with lower extremity (LE) OA is a public health priority. OBJECTIVE: To examine associations between diet quality and measures of physical function among overweight and obese older adults with self-reported LE OA. METHODS: 413 overweight and obese primarily African American adults ≥60 years old with LE OA were assessed. Diet quality was quantified using the Healthy Eating Index-2010 (HEI-2010) and Alternative Healthy Eating Index-2010 (AHEI-2010). The six-minute walk, 30-second chair-stands, and timed up-and-go tests were used to assess physical function. Unadjusted and multivariable linear regressions were performed to assess associations between the diet quality and measures of physical function. RESULTS: The mean age of the subjects was 67.8 (SD 5.9) years and mean BMI was 34.8 (SD 5.5) kg/m2. Adjusting for total calories, AHEI-2010 total score was associated with superior performance on the six-minute walk test. However, the association was attenuated when also controlling for age, gender, BMI, waist circumference, self-reported pain, and physical activity. HEI-2010 was not associated with the physical function measures. CONCLUSION: AHEI-2010 total score was positively associated with walking speed among older overweight and obese primarily AA older adults with LE OA. However, the association weakened when adjusting for subject covariates. The relationship between diet quality and physical function among health disparate populations should be further investigated in larger cohorts and using rigorous experimental study design.

Fit and Strong! Plus: Twelve and eighteen month follow-up results for a comparative effectiveness trial among overweight/obese older adults with osteoarthritis.

This comparative effectiveness trial compared the longer-term effectiveness (12 and 18 months) of the standard Fit & Strong! physical activity program to Fit & Strong! Plus, which combined physical activity and dietary weight loss. Outcomes were weight, diet quality, physical activity, osteoarthritis symptoms, performance measures, and anxiety/depression. In this study, 413 overweight/obese participants with OA, ≥60 years old and primarily African American, were randomly assigned to Fit & Strong! (F&S!) or Fit & Strong! Plus (F&S! Plus), with outcomes assessed at 2, 6, 12, and 18 months. 356 (86%) participants completed the 18-month visit. Compared with participants randomized to standard F&S!, F&S! Plus participants maintained longer-term benefits at 12 months in weight (mean change ± SE: -1.7 ± 0.3 kg for F&S! Plus vs -0.9 ± 0.3 kg for F&S!, p = 0.049), BMI (-0.6 ± 0.1 vs -0.3 ± 0.1 kg/m2, p = 0.04), waist circumference (-2.7 ± 0.6 vs -0.4 ± 0.6 cm, p = 0.004), and lower extremity strength (1.6 ± 0.2 vs 1.0 ± 0.2 chair stands, p = 0.046). At 18 months, F&S! Plus participants showed improved lower extremity strength (1.4 ± 0.2 vs. 0.7 ± 0.2 chair stands, p = 0.045. African American older adults in the F&S! Plus arm showed sustained modest improvements in weight, waist circumference, and lower extremity strength at 12 months and in lower extremity strength at 18 months compared to F&S!. Implications for the translation of evidence-based programs into community settings to support healthy behaviors in older adults are discussed.

Impact of Physical Activity and Weight Loss on Fat Mass, Glucose Metabolism, and Inflammation in Older African Americans with Osteoarthritis.

(1) Background: There are currently very few interventions performed within a community setting that compare the effects of physical activity (PA) versus PA plus weight loss on cancer and chronic disease risk in older African Americans. Therefore, we investigated the impact of an 8 week (24 session) PA intervention compared to a PA plus weight loss intervention on fat mass, glucose metabolism, and markers of inflammation in older, overweight and obese African Americans. (2) Methods: Subjects were randomized to a PA (n = 83) or PA plus weight loss (n = 72) intervention that met three times weekly for 8 weeks. At baseline and post-intervention, anthropometrics, body composition, systemic inflammation (high-sensitivity C-reactive protein, tumor necrosis factor-α, and interleukin 6), fasting glucose, insulin and homeostasis model assessment-insulin resistance (HOMA-IR) were determined. (3) Results: Subjects had a mean age of 67 years (SD = 5.3) and were mostly women (88%). The PA plus weight loss group lost more total and visceral fat than the PA group (-4.0% vs. +0.6% and -4.1% vs. +3.7%, respectively, p < 0.01 for both). Changes in inflammation and glucose metabolism were similar between groups post-intervention. Within the PA plus weight loss group only, serum insulin and HOMA-IR decreased significantly. (4) Conclusions: PA combined with weight loss can decrease total and visceral fat mass and improve insulin sensitivity, confirming that these cancer- and chronic disease-related risk factors are influenced by relatively modest lifestyle changes in the short term.

Fit & Strong! Plus Trial Outcomes for Obese Older Adults with Osteoarthritis.

BACKGROUND AND OBJECTIVES: We compared the effectiveness of standard Fit & Strong! (F&S!; targets physical activity [PA]) to Fit & Strong! Plus (F&S! Plus; targets PA and dietary weight loss) on weight, diet quality, and PA outcomes. RESEARCH DESIGN AND METHODS: We randomly assigned 413 overweight older adults with OA to the F&S! or F&S! Plus programs and assessed outcomes at 2 and 6 months. RESULTS: The F&S! Plus group lost -2.0 ± 0.2 kg (mean ± SE, 2% of starting weight) at 2 months that was maintained at 6 months. Two- and 6-month BMI and waist circumference improved significantly in the F&S! Plus group (p < .001). Diet quality at 2 months showed greater improvement in the F&S! Plus group: 4.6 ± 0.7 versus 2.0 ± 0.7, p = .006, with no significant difference between groups at 6 months. The F&S! Plus group differentially improved on PA engagement at 2 months and at 2 and 6 months in joint pain (6-month mean ± SE: -1.5 ± 0.3 vs -0.6 ± 0.3, p = .02), function (-4.7 ± 0.9 vs -1.5 ± 0.9, p = .01), and 6-min walk test (29.5 ± 5.1 m vs 14.1 ± 5.2 m, p = .04). DISCUSSION AND IMPLICATIONS: Adding a dietary weight loss component to F&S! achieved weight and waist circumference benefits that were maintained at 6 months. Importantly, the weight loss was accompanied by clinically meaningful improvements in OA symptoms and mobility. Future work should investigate minimum thresholds for weight reduction that improve long-term function in this population.

Diet Quality and Nutrient Intake of Urban Overweight and Obese Primarily African American Older Adults with Osteoarthritis.

Diet quality may be a unique target for preventing and managing obesity-related osteoarthritis (OA). Using the Healthy Eating Index-2010 (HEI-2010), this study examined the nutrient intake and diet quality of 400 urban overweight and obese primarily African American older adults with self-reported lower extremity OA. Associations between sociodemographic and health-related factors and diet quality were explored. Participants (mean age 67.8 years, SD 5.9) were included. Habitual dietary intake was assessed using a food frequency questionnaire (FFQ). Nutrient intake and diet quality were calculated from the FFQ. Results indicated that diet quality needs improvement (HEI-2010: 66.3 (SD 10.5)). Age, body mass index, employment (multivariable model only), and OA severity (bivariate model only) were significant predictors of HEI-2010 total score in linear models. Mean intakes for fiber, calcium, and vitamin D were below recommendations, while percentage of calories as total fat exceeded recommendations. These findings can inform future dietary intervention trials and public health messaging for a sub-population at a high risk for obesity-related OA.

Mechanisms of Change in Diet and Activity in the Make Better Choices 1 Trial.

OBJECTIVE: The Make Better Choices 1 trial demonstrated that participants with unhealthy diet and activity behaviors who were randomized to increase fruits/vegetables and decrease sedentary leisure achieved greater diet and activity improvement than those randomized to change other pairs of eating and activity behaviors. Participants randomized to decrease saturated fat and increase physical activity achieved the least diet-activity improvement. This study examined which psychological mechanisms mediated the effects of the study treatments on healthy behavior change. METHODS: Participants (n = 204) were randomized to 1 of 4 treatments: increase fruits/vegetables and physical activity; decrease saturated fat and sedentary leisure; decrease saturated fat and increase physical activity; increase fruits/vegetables and decrease sedentary leisure. Treatments provided 3 weeks of remote coaching supported by mobile decision support technology and financial incentives. Mediational analyses were performed to examine whether changes in positive and negative affect, and self-efficacy, stages of readiness to change, liking, craving and attentional bias for fruit/vegetable intake, saturated fat intake, physical activity, and sedentary leisure explained the impact of the treatments on diet-activity improvement. RESULTS: Greater diet-activity improvement in those randomized to increase fruits/vegetables and decrease sedentary leisure was mediated by increased self-efficacy (indirect effect estimate = 0.04; 95% bias corrected CI, 0.003-0.11). All treatments improved craving, stage of change and positive affect. CONCLUSION: Accomplishing healthy lifestyle changes for 3 weeks improves positive affect, increases cravings for healthy foods and activities, and enhances readiness to make healthy behavior changes. Maximal diet and activity improvement occurs when interventions enhance self-efficacy to make multiple healthy behavior changes. (PsycINFO Database Record

Integrating technology into standard weight loss treatment: a randomized controlled trial.

BACKGROUND: A challenge in intensive obesity treatment is making care scalable. Little is known about whether the outcome of physician-directed weight loss treatment can be improved by adding mobile technology. METHODS: We conducted a 2-arm, 12-month study (October 1, 2007, through September 31, 2010). Seventy adults (body mass index >25 and ≤40 [calculated as weight in kilograms divided by height in meters squared]) were randomly assigned either to standard-of-care group treatment alone (standard group) or to the standard and connective mobile technology system (+mobile group). Participants attended biweekly weight loss groups held by the Veterans Affairs outpatient clinic. The +mobile group was provided personal digital assistants to self-monitor diet and physical activity; they also received biweekly coaching calls for 6 months. Weight was measured at baseline and at 3-, 6-, 9-, and 12-month follow-up. RESULTS: Sixty-nine adults received intervention (mean age, 57.7 years; 85.5% were men). A longitudinal intent-to-treat analysis indicated that the +mobile group lost a mean of 3.9 kg more (representing 3.1% more weight loss relative to the control group; 95% CI, 2.2-5.5 kg) than the standard group at each postbaseline time point. Compared with the standard group, the +mobile group had significantly greater odds of having lost 5% or more of their baseline weight at each postbaseline time point (odds ratio, 6.5; 95% CI, 2.5-18.6). CONCLUSIONS: The addition of a personal digital assistant and telephone coaching can enhance short-term weight loss in combination with an existing system of care. Mobile connective technology holds promise as a scalable mechanism for augmenting the effect of physician-directed weight loss treatment.

Past major depression and smoking cessation outcome: a systematic review and meta-analysis update.

AIMS: To update our prior meta-analysis that showed past major depression (MD+) to be unrelated to smoking cessation outcome. METHODS: Eligible trials included 14 from our original review and 28 identified through an updated systematic review (2000-2009). We coded for assessment of past MD, exclusion for recent MD episode (MDE; ≤6 months versus no exclusion), duration/modality of cognitive behavioral treatment (CBT; face-to-face versus self-help) and other factors. To minimize influence of experimental treatments that may selectively benefit MD+ smokers we analyzed placebo/lowest intensity control arms only. Study-specific ORs for the effect of past MD on short-term (≤3 months) and long-term (≥6 months) abstinence were estimated and combined using random effects. Two-way interaction models of past MD with study methodology and treatment factors were used to evaluate hypothesized moderators of the past MD-abstinence association. RESULTS: MD+ smokers had 17% lower odds of short-term abstinence (n = 35, OR = 0.83, 95% CI = 0.72-0.95, P = 0.009) and 19% lower odds of long-term abstinence (n = 38, OR = 0.81, 95% CI = 0.67-0.97, P = 0.023) than MD- smokers after excluding the sole study of varenicline because of its antidepressant properties. The association between past MD and abstinence was affected by methodological (recent MDE exclusion, type of MD assessment) and treatment (CBT modality) factors. CONCLUSIONS: Past major depression has a modest adverse effect on abstinence during and after smoking cessation treatment. An increased focus on the identification of effective treatments or treatment adaptations that eliminate this disparity in smoking cessation for MD+ smokers is needed.

A smartphone-supported weight loss program: design of the ENGAGED randomized controlled trial.

BACKGROUND: Obesity remains a major public health challenge, demanding cost-effective and scalable weight management programs. Delivering key treatment components via mobile technology offers a potential way to reduce expensive in-person contact, thereby lowering the cost and burden of intensive weight loss programs. The ENGAGED study is a theory-guided, randomized controlled trial designed to examine the feasibility and efficacy of an abbreviated smartphone-supported weight loss program. METHODS/DESIGN: Ninety-six obese adults (BMI 30-39.9 kg/m2) will be randomized to one of three treatment conditions: (1) standard behavioral weight loss (STND), (2) technology-supported behavioral weight loss (TECH); or (3) self-guided behavioral weight loss (SELF). All groups will aim to achieve a 7% weight loss goal by reducing calorie and fat intake and progressively increasing moderate intensity physical activity to 175 minutes/week. STND and TECH will attend 8 group sessions and receive regular coaching calls during the first 6 months of the intervention; SELF will receive the Group Lifestyle Balance Program DVD's and will not receive coaching calls. During months 1-6, TECH will use a specially designed smartphone application to monitor dietary intake, body weight, and objectively measured physical activity (obtained from a Blue-tooth enabled accelerometer). STND and SELF will self-monitor on paper diaries. Linear mixed modeling will be used to examine group differences on weight loss at months 3, 6, and 12. Self-monitoring adherence and diet and activity goal attainment will be tested as mediators. DISCUSSION: ENGAGED is an innovative weight loss intervention that integrates theory with emerging mobile technologies. We hypothesize that TECH, as compared to STND and SELF, will result in greater weight loss by virtue of improved behavioral adherence and goal achievement. TRIAL REGISTRATION: NCT01051713.

Technology Interventions to Curb Obesity: A Systematic Review of the Current Literature.

Obesity is a public health crisis that has reached epidemic proportions. Although intensive behavioral interventions can produce clinically significant weight loss, their cost to implement, coupled with resource limitations, pose significant barriers to scalability. To overcome these challenges, researchers have made attempts to shift intervention content to the Internet and other mobile devices. This article systematically reviews the recent literature examining technology-supported interventions for weight loss and maintenance among overweight and obese adults. Thirteen studies were identified that satisfied our inclusion criteria (12 weight loss trials, 1 weight maintenance trial). Our findings suggest that technology interventions may be efficacious at producing weight loss. However, several studies are limited by methodologic shortcomings. There are insufficient data to evaluate their efficacy for weight maintenance. Further research is needed that employs state-of-the-art methodology, with careful attention being paid to adherence and fidelity to intervention protocols.

Multiple behavior changes in diet and activity: a randomized controlled trial using mobile technology.

BACKGROUND: Many patients exhibit multiple chronic disease risk behaviors. Research provides little information about advice that can maximize simultaneous health behavior changes. METHODS: To test which combination of diet and activity advice maximizes healthy change, we randomized 204 adults with elevated saturated fat and low fruit and vegetable intake, high sedentary leisure time, and low physical activity to 1 of 4 treatments: increase fruit/vegetable intake and physical activity, decrease fat and sedentary leisure, decrease fat and increase physical activity, and increase fruit/vegetable intake and decrease sedentary leisure. Treatments provided 3 weeks of remote coaching supported by mobile decision support technology and financial incentives. During treatment, incentives were contingent on using the mobile device to self-monitor and attain behavioral targets; during follow-up, incentives were contingent only on recording. The outcome was standardized, composite improvement on the 4 diet and activity behaviors at the end of treatment and at 5-month follow-up. RESULTS: Of the 204 individuals randomized, 200 (98.0%) completed follow-up. The increase fruits/vegetables and decrease sedentary leisure treatments improved more than the other 3 treatments (P < .001). Specifically, daily fruit/vegetable intake increased from 1.2 servings to 5.5 servings, sedentary leisure decreased from 219.2 minutes to 89.3 minutes, and saturated fat decreased from 12.0% to 9.5% of calories consumed. Differences between treatment groups were maintained through follow-up. Traditional dieting (decrease fat and increase physical activity) improved less than the other 3 treatments (P < .001). CONCLUSIONS: Remote coaching supported by mobile technology and financial incentives holds promise to improve diet and activity. Targeting fruits/vegetables and sedentary leisure together maximizes overall adoption and maintenance of multiple healthy behavior changes.

PDA+: A Personal Digital Assistant for Obesity Treatment - an RCT testing the use of technology to enhance weight loss treatment for veterans.

BACKGROUND: Obese adults struggle to make the changes necessary to achieve even modest weight loss, though a decrease in weight by as little as 10% can have significant health benefits. Failure to meet weight loss goals may in part be associated with barriers to obesity treatment. Wide-spread dissemination of evidence-based obesity treatment faces multiple challenges including cost, access, and implementing the programmatic characteristics on a large scale. AIMS: The PDA+: A Personal Digital Assistant for Obesity Treatment randomized controlled trial (RCT) was designed to test whether a PDA-based behavioral intervention enhances the effectiveness of the existing group weight loss treatment program at VA Medical Centers Managing Overweight/Obese Veterans Everywhere (MOVE!). We also aim to introduce technology as a way to overcome systemic barriers of traditional obesity treatment. METHODS/DESIGN: Veterans enrolled in the MOVE! group at the Hines Hospital VAMC with BMI ≥ 25 and ≤ 40 and weigh < 400 pounds, experience chronic pain (≥ 4 on the NRS-I scale for ≥ 6 months prior to enrollment) and are able to participate in a moderate intensity exercise program will be recruited and screened for eligibility. Participants will be randomized to receive either: a) MOVE! treatment alone (Standard Care) or b) Standard Care plus PDA (PDA+). Those randomized to PDA+ will record dietary intake, physical activity, and weight on the PDA. In addition, they will also record mood and pain intensity, and receive biweekly telephone support for the first 6-months of the 12-month study. All participants will attend in-person lab sessions every three months to complete questionnaires and for the collection of anthropomorphic data. Weight loss and decrease in pain level intensity are the primary outcomes. DISCUSSION: The PDA+ trial represents an important step in understanding ways to improve the use of technology in obesity treatment. The trial will address barriers to obesity care by implementing effective behavioral components of a weight loss intervention and delivering high intensity, low cost obesity treatment. This RCT also tests an intervention approach supported by handheld technology in a population traditionally considered to have lower levels of technology literacy. TRIAL REGISTRATION: ClinicalTrials.gov: NCT00371462.

Make Better Choices (MBC): study design of a randomized controlled trial testing optimal technology-supported change in multiple diet and physical activity risk behaviors.

BACKGROUND: Suboptimal diet and physical inactivity are prevalent, co-occurring chronic disease risk factors, yet little is known about how to maximize multiple risk behavior change. Make Better Choices, a randomized controlled trial, tests competing hypotheses about the optimal way to promote healthy change in four bundled risk behaviors: high saturated fat intake, low fruit and vegetable intake, low physical activity, and high sedentary leisure screen time. The study aim is to determine which combination of two behavior change goals--one dietary, one activity--yields greatest overall healthy lifestyle change. METHODS/DESIGN: Adults (n = 200) with poor quality diet and sedentary lifestyle will be recruited and screened for study eligibility. Participants will be trained to record their diet and activities onto a personal data assistant, and use it to complete two weeks of baseline. Those who continue to show all four risk behaviors after baseline recording will be randomized to one of four behavior change prescriptions: 1) increase fruits and vegetables and increase physical activity, 2) decrease saturated fat and increase physical activity, 3) increase fruits and vegetable and decrease saturated fat, or 4) decrease saturated fat and decrease sedentary activity. They will use decision support feedback on the personal digital assistant and receive counseling from a coach to alter their diet and activity during a 3-week prescription period when payment is contingent upon meeting behavior change goals. They will continue recording on an intermittent schedule during a 4.5-month maintenance period when payment is not contingent upon goal attainment. The primary outcome is overall healthy lifestyle change, aggregated across all four risk behaviors. DISCUSSION: The Make Better Choices trial tests a disseminable lifestyle intervention supported by handheld technology. Findings will fill a gap in knowledge about optimal goal prescription to facilitate simultaneous diet and activity change. Results will shed light on which goal prescription maximizes healthful lifestyle change. TRIAL REGISTRATION: Clinical Trials Gov. Identifier NCT00113672.
