Background As COVID-19 continues to spread globally, it is important to understand psychological factors that may influence compliance with social distancing. Purpose The present study examined whether Theory of Planned Behavior (TPB) constructs were associated with social distancing, with a focus on exploring moderators of the intention–behavior relationship. Methods Using a longitudinal design, U.S. adults (N = 507) self-reported TPB constructs and social distancing behavior at baseline and 3 months later. Participants were from 48 U.S. States and the District of Columbia and were on average 50.39 years old (SD = 15.32, range = 18–80). The majority were Non-Hispanic White (71.6%), had a bachelor’s degree or higher (55.3%), and resided in suburban areas (55.8%). Results While positive attitudes toward social distancing increased over time (p = .002), subjective norms weakened (p < .001) and perceived behavioral control (PBC) remained stable (p = .22). Interestingly, despite an increase in intentions from baseline to follow-up (p < .001), there was a significant decrease in social distancing behavior over time (p < .001). Consistent with the TPB, baseline attitudes (p < .001), subjective norms (p < .001), and PBC (p < .001) for social distancing were all associated with baseline intentions to social distance. In turn, baseline intentions were significantly associated with social distancing behavior at follow-up (p < .001). Younger adults (p < .001) and non-White participants (p = .002) displayed a greater intention–behavior gap relative to older and White participants. In contrast, participants with more stable intentions over time displayed a stronger intention–behavior relationship (p < .001). Conclusions Targeting individuals’ attitudes, norms, and PBC may effectively promote protective behaviors intended to mitigate the spread of COVID-19 and similar viral outbreaks. Future research should examine effective strategies for translating social distancing intentions into actions., Social distancing attitudes, norms, perceived behavioral control, and intentions were associated with social distancing behavior at 3-month follow-up. Racial minorities and younger adults displayed larger intention-behavior gaps.

The current study sought to identify subgroups of adult drinkers who differ in their level of association between alcohol-related Theory of Planned Behavior (TPB) constructs (attitudes, perceived norms, self-efficacy, and intentions), and explore if distinct subgroup profiles relate to alcohol use two weeks later.Participants (N = 121) were recruited to participate in a two-week study about daily experiences with exercise and alcohol (Alcohol attitudes, subjective norms, alcohol refusal self-efficacy, and intentions were used to create class membership. Behavioral outcomes included (1) drinking frequency, (2) drinking quantity, and (3) drinking to get drunk.Two classes of drinkers were determined - Class 1 was categorized by moderate scores on all constructs, whereas Class 2 was categorized by moderate scores on attitudes and high scores on norms, alcohol refusal self-efficacy, and intentions. Class designation was associated with frequency, but not quantity of use.The current study suggests that a minority of individuals who score moderately across all constructs should receive intervention efforts that focus on just those included in the TPB, while the vast majority may require additional constructs to be addressed.

Background In August 2019, the U.S. Food and Drug Administration proposed a set of 13 new graphic warnings for cigarette packaging and advertisements. Purpose We evaluated these warnings relative to text-only equivalents for their ability to educate the public regarding harms of smoking and influence outcomes associated with quitting. Methods In an experimental within-subjects design, U.S. adult nonsmokers, smokers, and dual smoker/electronic cigarette (e-cigarette) users (N = 412) recruited from an online internet platform evaluated the newly proposed graphic warnings and corresponding text-only warnings on understandability, perceived new knowledge, worry elicited about the content of the warning, discouragement from smoking, and encouragement to use e-cigarettes. Results Graphic warnings were generally rated as providing better understanding, more new knowledge, eliciting more worry about harms of smoking, and providing more discouragement from smoking relative to text-only warnings. Conclusions The newly proposed graphic warnings could influence important responses to warnings associated with motivation to reduce smoking.

Background: Physician denial of patient requests is associated with lower patient satisfaction. Our objective was to explore factors that influence physician request denial and patient satisfaction after request denial. Methods: Cross-sectional observational study of 1141 adult patients seen during 1319 outpatient visits with 56 primary care physicians. We measured patients9 postvisit self-report of requests and request fulfillment, visit satisfaction, sociodemographics, health status, symptom burden, life satisfaction, medical skepticism, and whether patients saw their usual physician and a faculty or resident physician. We used mixed-effects regression analyses to identify predictors of request denial and visit satisfaction among patients who had a request denied. Results: Patients made at least 1 request at 867 visits (65.7%) with at least 1 denied request reported at 182 visits (21.0%). Patients who saw their usual physician were less likely to report a request denial (adjusted Odds Ratio [aOR], 0.61; 95% CI, 0.42 to 0.88), and patients with the highest symptom burden (aOR, 2.21; 95% CI, 1.38 to 3.55) or greater medical skepticism (aOR, 1.35; 95% CI, 1.03 to 1.78) were more likely to report request denials. After request denials, patients seeing their usual physicians reported significantly greater visit satisfaction compared with not seeing their usual physician (adjusted percentile rank in visit satisfaction: 12.4%; 95% CI, 3.5% to 21.2%). Conclusions: Approximately one fifth of visits in primary care have a denied request. Having an office visit with one9s usual physician is associated with reduced likelihood of request denial and may mitigate the adverse impacts of request denial on patient visit satisfaction.

Importance Opioid-related mortality and national prescribing guidelines have led to tapering of doses among patients prescribed long-term opioid therapy for chronic pain. There is limited information about risks related to tapering, including overdose and mental health crisis. Objective To assess whether there are associations between opioid dose tapering and rates of overdose and mental health crisis among patients prescribed stable, long-term, higher-dose opioids. Design, Setting, and Participants Retrospective cohort study using deidentified medical and pharmacy claims and enrollment data from the OptumLabs Data Warehouse from 2008 to 2019. Adults in the US prescribed stable higher doses (mean ≥50 morphine milligram equivalents/d) of opioids for a 12-month baseline period with at least 2 months of follow-up were eligible for inclusion. Exposures Opioid tapering, defined as at least 15% relative reduction in mean daily dose during any of 6 overlapping 60-day windows within a 7-month follow-up period. Maximum monthly dose reduction velocity was computed during the same period. Main Outcomes and Measures Emergency or hospital encounters for (1) drug overdose or withdrawal and (2) mental health crisis (depression, anxiety, suicide attempt) during up to 12 months of follow-up. Discrete time negative binomial regression models estimated adjusted incidence rate ratios (aIRRs) of outcomes as a function of tapering (vs no tapering) and dose reduction velocity. Results The final cohort included 113 618 patients after 203 920 stable baseline periods. Among the patients who underwent dose tapering, 54.3% were women (vs 53.2% among those who did not undergo dose tapering), the mean age was 57.7 years (vs 58.3 years), and 38.8% were commercially insured (vs 41.9%). Posttapering patient periods were associated with an adjusted incidence rate of 9.3 overdose events per 100 person-years compared with 5.5 events per 100 person-years in nontapered periods (adjusted incidence rate difference, 3.8 per 100 person-years [95% CI, 3.0-4.6]; aIRR, 1.68 [95% CI, 1.53-1.85]). Tapering was associated with an adjusted incidence rate of 7.6 mental health crisis events per 100 person-years compared with 3.3 events per 100 person-years among nontapered periods (adjusted incidence rate difference, 4.3 per 100 person-years [95% CI, 3.2-5.3]; aIRR, 2.28 [95% CI, 1.96-2.65]). Increasing maximum monthly dose reduction velocity by 10% was associated with an aIRR of 1.09 for overdose (95% CI, 1.07-1.11) and of 1.18 for mental health crisis (95% CI, 1.14-1.21). Conclusions and Relevance Among patients prescribed stable, long-term, higher-dose opioid therapy, tapering events were significantly associated with increased risk of overdose and mental health crisis. Although these findings raise questions about potential harms of tapering, interpretation is limited by the observational study design.

This study aims to determine the rate of chronic pain in a community sample of young adult cannabis users, assess the extent to which pain relief is an important motivation for cannabis use, and explore differences in consumption patterns and problem behaviors between users with and without chronic pain. The study design was cross-sectional. Self-selected community-dwelling young adults (ages 18–29 years; n = 143) who regularly use cannabis completed an online survey. Results revealed that approximately 40% of the sample met the criteria for chronic pain, and pain relief was their primary motivation for use. There were no differences between groups with respect to frequency of use or estimated potency of their preferred strains; however, users with chronic pain reported using a wider variety of administration methods and a greater quantity of cannabis with each use. Users with chronic pain also reported more extensive histories of use, with younger age at initiation and longer duration of regular use. Despite riskier consumption patterns, there were no between-group differences in negative consequences owing to use after controlling for gender and educational status. On average, the total sample reported approximately 8 problems in the past 30 days owing to use. These findings suggest that chronic pain is commonly experienced among young adult cannabis users and pain relief is the primary motivation for users with pain. For some users, clinically significant chronic pain and pain-related interference persist despite heavy use. Cannabis users with and without chronic pain report experiencing several negative consequences owing to their use. Perspective This article compares motivations for cannabis use and describes differences in consumption patterns among a community sample of young adult users with and without chronic pain. This information may be useful for providers who assess and treat pain in young adults, particularly in settings that have legalized recreational use.

Background: Patient requests for tests, treatments, or referrals occur frequently during primary care visits and pose challenges for clinicians to address, but little is known about patient characteristics that may predict requests. Objective: To identify patient characteristics associated with a higher rate of patient requests during primary care visits. Design, Setting, and Sample: Cross-sectional analyses of data from 1141 adult patients attending 1319 visits with 56 primary care physicians (including 45 resident and 11 faculty physicians) in an academic family medicine practice. Measurements: Postvisit patient surveys including measures of patient requests for tests, prescriptions, and referrals; sociodemographics; mental and physical health status; symptom bother or worry (3-item scale; range, 3 to 15; Cronbach9s α = 0.83); global life satisfaction; medical skepticism; and Five Factor Model personality traits. Results: Patients made 1 or more requests in 867 visits (65.7%). In multivariate analyses of the within-visit request count, the following patient variables were statistically significantly associated with a higher rate of requests: age in years (incidence rate ratio [IRR], 1.01 [95% CI, 1.00 to 1.01]), increased symptom bother or worry (IRR, 1.06 [95% CI, 1.03 to 1.08]), a more extroverted personality (IRR, 1.12 [95% CI, 1.03 to 1.08]), greater life satisfaction (IRR, 1.01 [95% CI, 1.00 to 1.02]), and any prior encounter with the visit physician (IRR, 1.17 [95% CI, 1.04 to 1.32]). Conclusions: Primary care physicians should expect a greater frequency of requests from older patients, patients with greater symptoms bother or worry, more extroverted patients, patients with greater global life satisfaction, and patients with whom they have had prior visits.

The COVID-19 global pandemic is an unprecedented health threat for which behavior is critical to prevent spread and personal factors could contribute to decisions for protective action. The purpose of this study was to describe associations of COVID-19 related behaviors capturing a snapshot in time during the height of the first wave of the pandemic. We tested perceptions of likelihood and severity of infection, worry, and their associations with behavior. We further explored relationships by demographic characteristics, and tested main and interactive relationships between these characteristics and beliefs and protective behaviors. Using an online cross-sectional survey, U.S. adults (N = 795) reported their perceptions of likelihood and severity of, and worry about, contracting COVID-19 for self and others, and engagement in protective behaviors. In bivariate tests, all cognitive and affective beliefs were positively associated with hygiene behaviors, but only worry and personal and others’ severity were associated with greater likelihood of social distancing. Controlling for other beliefs and demographic factors, perceived personal severity remained associated with social distancing, and worry with hygiene behaviors. How people think and feel about risk could have implications for communicating information about this novel health threat and motivating action to mitigate its spread.

INTRODUCTION: There are no population-level estimates in the United States for achievement of blood pressure goals in patients with diabetes and hypertension by obesity weight class. AIM: We sought to examine the relationship between the extent of obesity and the achievement of guideline-recommended blood pressure goals and other quality of care metrics among patients with diabetes. METHODS: We conducted an observational population-based cohort study of electronic health data of three large health systems from 2010–2012 in rural, urban and suburban settings of 51,229 adults with diabetes. Outcomes were achievement of diabetes quality of care metrics: blood pressure, A1c, and LDL control, and A1c and LDL testing. Two blood pressure goals were examined given the recommendation for adults with diabetes of 130/80 mmHg from JNC7 and the recommendation of 140/90 mmHg from JNC8 in 2014. RESULTS: Patients in obesity classes I, II, and III with diagnosed hypertension were less likely to achieve blood pressure control at both the 140/90 mmHg and 130/80 mmHg control levels. The patients from obesity class III had the lowest likelihood of achieving control at the 130/80 mmHg goal, and control was markedly worse for the 130/80 mmHg threshold in all weight classes. There were minimal to no differences by weight class in LDL and A1c control and LDL and A1c testing. CONCLUSIONS: Although the cardiovascular risk for patients with obesity and diabetes is greater than for non-obese patients with diabetes, we found that patients with obesity are even further behind in achieving blood pressure control.

Importance A 2016 Centers for Disease Control and Prevention prescribing guideline cautioned against higher-dose long-term opioid therapy and recommended tapering daily opioid doses by approximately 10% per week if the risks outweigh the benefits. Warnings have since appeared regarding potential hazards of rapid opioid tapering. Objectives To characterize US trends in opioid dose tapering among patients prescribed long-term opioids from 2008 to 2017 and identify patient-level variables associated with tapering and a more rapid rate of tapering. Design, Setting, and Participants This retrospective cohort study used deidentified medical and pharmacy claims and enrollment records for 99 874 commercial insurance and Medicare Advantage enrollees, representing a diverse mixture of ages, races/ethnicities, and geographical regions across the United States. Adults with stable, higher-dosage (mean, ≥50 morphine milligram equivalents [MMEs]/d) opioid prescriptions for a 12-month baseline period and 2 or more months of follow-up from January 1, 2008, to December 31, 2017, were included in the study. Main Outcomes and Measures Tapering was defined as 15% or more relative reduction in mean daily MME during any of 6 overlapping 60-day windows within a 7-month follow-up period. The rate of tapering was computed as the maximum monthly percentage dose reduction. Results Among the 99 874 participants (53 358 [53.4%] women; mean [SD] age, 57.4 [11.8] years), from 2008 to 2015, the age- and sex-standardized percentage of patients tapering daily opioid doses increased from 12.7% to 16.2% (adjusted incidence rate ratio [aIRR] per year, 1.05 [95% CI, 1.05-1.06]) before increasing to 18.6% in 2016 and 23.1% in 2017 (aIRR in 2016-2017 vs 2008-2015, 1.16 [95% CI, 1.12-1.20]). Patient-level covariates associated with tapering included female sex (aIRR, 1.09 [95% CI, 1.07-1.11]) and higher baseline dose (aIRR for ≥300 MMEs/d vs 50-89 MMEs/d, 2.19 [95% CI, 2.12-2.27]). Among patients tapering daily opioid doses, the mean (SD) maximum dose reduction was 34.0% (27.4%) per month, and 26.5% of patients had a maximum tapering rate exceeding 40% per month (ie, faster than 10% per week). Higher maximum dose reduction rate was associated with age 18 to 34 years (vs older age groups), male sex, a high school education or less (vs more education), small town or rural residence (vs metropolitan, micropolitan, or unknown), a Charlson Comorbidity Index score of 3 or higher (vs 0) (adjusted difference, 1.9% [95% CI, 0.9%-2.9%]), lower baseline doses (50-89 MMEs vs 150-299 or ≥300 MMEs), and a recent drug overdose (adjusted difference, 10.2% [95% CI, 6.8%-13.6%]). Conclusions and Relevance Patients using long-term opioid therapy are increasingly undergoing dose tapering, particularly women and those prescribed higher doses; in addition, dose tapering has become more common since 2016. Many patients undergoing tapering reduce daily doses at a rapid maximum rate.

Young adults (aged 18 to 39years) have the lowest hypertension control rates compared with older adults. Shorter follow-up encounter intervals are associated with faster hypertension control rates in older adults; however, optimal intervals are unknown for young adults. The study objective was to evaluate the relationship between ambulatory blood pressure encounter intervals (average number of provider visits with blood pressures over time) and hypertension control rates among young adults with incident hypertension. A retrospective analysis was conducted of patients aged 18 to 39 years (n = 2990) with incident hypertension using Kaplan-Meier survival and Cox proportional hazards analyses over 24months. Shorter encounter intervals were associated with higher hypertension control: 6months (13%). Young adults with shorter encounter intervals also had lower medication initiation, supporting the effectiveness of lifestyle modifications. Sustainable interventions for timely young adult follow-up are essential to improve hypertension control in this hard-to-reach population.

BackgroundPatient experience measures are widely used to compare performance at the individual physician level.ObjectiveTo assess the impact of unmeasured patient characteristics on visit-level patient experience measures and the sample sizes required to reliably measure patient experience at the primary care physician (PCP) level.DesignRepeated cross-sectional design.SettingAcademic family medicine practice in California.ParticipantsOne thousand one hundred forty-one adult patients attending 1319 visits with 56 PCPs (including 45 resident and 11 faculty physicians).MeasurementsPost-visit patient experience surveys including patient measures used for standard adjustment as recommend by the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Consortium and additional patient characteristics used for expanded adjustment (including attitudes toward healthcare, global life satisfaction, patient personality, current symptom bother, and marital status).ResultsThe amount of variance in patient experience explained doubled with expanded adjustment for patient characteristics compared with standard adjustment (R2 = 20.0% vs. 9.6%, respectively). With expanded adjustment, the amount of variance attributable to the PCP dropped from 6.1% to 3.4% and the required sample size to achieve a reliability of 0.90 in the physician-level patient experience measure increased from 138 to 255 patients per physician. After ranking of the 56 PCPs by average patient experience, 8 were reclassified into or out of the top or bottom quartiles of average experience with expanded as compared to standard adjustment [14.3% (95% CI: 7.0-25.2%)].ConclusionsWidely used methods for measuring PCP-level patient experience may not account sufficiently for influential patient characteristics. If methods were adapted to account for these characteristics, patient sample sizes for reliable between-physician comparisons may be too large for most practices to obtain.

Objective To find clinically relevant combinations of chronic conditions among patients with diabetes and to examine their relationships with six diabetes quality metrics. Data Sources/Study Setting Twenty-nine thousand five hundred and sixty-two adult patients with diabetes seen at eight Midwestern U.S. health systems during 2010–2011. Study Design We retrospectively evaluated the relationship between six diabetes quality metrics and patients' combinations of chronic conditions. We analyzed 12 conditions that were concordant with diabetes care to define five mutually exclusive combinations of conditions (“classes”) based on condition co-occurrence. We used logistic regression to quantify the relationship between condition classes and quality metrics, adjusted for patient demographics and utilization. Data Collection We extracted electronic health record data using a standardized algorithm. Principal Findings We found the following condition classes: severe cardiac, cardiac, noncardiac vascular, risk factors, and no concordant comorbidities. Adjusted odds ratios and 95 percent confidence intervals for glycemic control were, respectively, 1.95 (1.7–2.2), 1.6 (1.4–1.9), 1.3 (1.2–1.5), and 1.3 (1.2–1.4) compared to the class with no comorbidities. Results showed similar patterns for other metrics. Conclusions Patients had distinct quality metric achievement by condition class, and those in less severe classes were less likely to achieve diabetes metrics.

BACKGROUND: In a prior study, we found patient satisfaction was associated with mortality. However, that study included few deaths, yielding wide confidence intervals, was criticized for possible morbidity under-adjustment, and lacked power to explore sociodemographic moderation. OBJECTIVE: To revisit the satisfaction-mortality association in a larger national sample, allowing more precise risk estimates, sequential morbidity adjustment, and exploration of sociodemographic moderation. DESIGN: Prospective cohort study. PARTICIPANTS: 2000–2015 Adult Medical Expenditures Panel Surveys (MEPS) respondents (N = 92,952), each enrolled for 2 consecutive years. MAIN MEASURES: We used five Consumer Assessment of Health Plans Survey (CAHPS) items to assess patients’ year 1 satisfaction with their clinicians. Death during the 2 years of MEPS participation was determined by proxy report. We modeled the satisfaction-mortality association in sequential regressions: model 1 included sociodemographics, model 2 added health status (approximating recommended CAHPS adjustment), and model 3 added smoking status, disease burden, and healthcare utilization. KEY RESULTS: Satisfaction was not associated with mortality in model 1. In model 2, higher satisfaction was associated with higher mortality (hazard ratios [95% CIs] for 2nd, 3rd, and 4th (top) quartiles vs. 1st quartile: 1.28 (1.01, 1.62), P = 0.04; 1.43 (1.12, 1.82), P = 0.004; and 1.57 (1.25, 1.98), P

Most patients with diabetes have comorbid chronic conditions that could support (concordant) or compete with (discordant) diabetes care. We sought to determine the impact of the number of concordant and discordant chronic conditions on diabetes care quality.Logistic regression analysis of electronic health record data from 7 health systems on 24,430 patients with diabetes aged 18-75 years. Diabetes testing and control quality care goals were the outcome variables. The number of diabetes-concordant and the number of diabetes-discordant conditions were the main explanatory variables. Analysis was adjusted for health care utilization, health system and patient demographics.A higher number of concordant conditions were associated with higher odds of achieving testing and control goals for all outcomes except blood pressure control. There was no to minimal positive association between the number of discordant conditions and outcomes, except for cholesterol testing which was less likely with 4+ discordant conditions.Having more concordant conditions makes diabetes care goal achievement more likely. The number of discordant conditions has a smaller, inconsistently significant impact on diabetes goal achievement. Interventions to improve diabetes care need to align with a patient's comorbidities, including the absence of comorbidities, especially concordant comorbidities.

OBJECTIVE Although graphic cigarette warnings have important benefits that may aid in motivating smoking quit attempts and discouraging smoking initiation, 1 possible negative consequence might be psychological reactance to graphic warnings. Reactance to warnings might be shaped by stereotypical views of smokers. This research examined the associations of positive and negative smoker stereotypes with perceptions of the educational value of warnings as well as affective and motivational responses to them. METHOD Using a cross-sectional design, young adult smokers and nonsmokers (N = 396) completed an online questionnaire assessing positive and negative smoker stereotypes and then evaluated a series of graphic-plus-text and text-only cigarette warnings on perceived new knowledge gained from the warning, understandability of the warning, worry about the consequences of smoking elicited by the warning, and discouragement from smoking elicited by the warning. RESULTS Negative smoker stereotypes were associated with all warning perceptions-more negative stereotypes were associated with higher levels of perceived new knowledge, perceived understandability, worry, and discouragement from smoking. Positive smoker stereotypes were only associated with more perceived new knowledge. Neither smoking status nor warning type moderated the relationships between smoking stereotypes and warning evaluations. CONCLUSIONS Focusing on enhancing negative smoker portrayals, rather than reducing positive portrayals, may be more effective for antismoking campaigns. (PsycINFO Database Record

Background Chronic alcohol abuse is related to numerous deleterious neurobiological consequences, including loss of gray matter, damage to white matter (WM), and impairment of cognitive and motor functions. Aerobic exercise has been demonstrated to slow cognitive decline and decrease the negative neural changes resulting from normal aging and from several diseases. It is possible that exercise may also prevent or repair alcohol-related neurological damage. This study tested the hypothesis that aerobic exercise protects WM in anterior and dorsal areas of the brain from damage related to heavy alcohol use. Methods Sixty individuals underwent a diffusion tensor imaging session and completed measures of alcohol consumption, loss of control over drinking, and aerobic exercise participation. Analyses examined the relationship of exercise, alcohol, and their interaction to fractional anisotropy (FA) in the superior longitudinal fasciculus (SLF), external capsule (EC), superior and anterior corona radiata, and fornix. The relationship of aerobic exercise and alcohol consumption to self-reported loss of control over drinking were also examined. Results A significant interaction was observed between alcohol consumption and aerobic exercise participation on FA in the SLF and EC. In the models examining loss of control over drinking, a significant interaction between aerobic exercise and alcohol consumption was observed, such that alcohol consumption was associated with loss of control more strongly for low exercisers than high exercisers. Conclusions These results indicate that the association between heavy alcohol consumption and WM damage in the EC and SLF and the association between alcohol consumption and loss of control over drinking are greater among individuals who do not exercise regularly. These results are consistent with the notion that exercise may protect WM integrity from alcohol-related damage.

Affective responses during exercise are often important determinants of exercise initiation and maintenance. Current physical activity may be one individual difference that is associated with the degree to which individuals have positive (or negative) affective experiences during exercise. The objective of this study was to explore physical and cognitive explanations of the relationship between current activity status (more versus less active) and affective response during a 30-minute bout of moderate-intensity exercise. Participants reported their current level of physical activity, exercise self-efficacy and affect during a 30-minute bout of moderate-intensity exercise. More active individuals experienced higher levels of positive affect and tranquillity and lower levels of negative affect and fatigue during exercise. Multivariate models for each affective state indicated separate processes through which physical activity may be associated with changes in affect during exercise. These models indicate that affect experienced during physical activity is related to the current activity level and these relationships can be partially explained by the physical and cognitive factors explored in this study. Recommendations for future research to elucidate whether positive affective response to physical activity improves as a function of becoming more active over time are discussed.

Objective To explore how physician training in self-efficacy enhancing interviewing techniques (SEE IT) affects patient psychological health behavior change mediators (HBCMs). Methods We analyzed data from 131 patients visiting primary care physicians ≥4 months after the physicians participated in a randomized controlled trial. Experimental arm physicians (N = 27) received SEE IT training during three ≤20 min standardized patient instructor (SPI) visits. Control physicians (N = 23) viewed a diabetes medications video during one SPI visit. Physicians were blinded to patient participation. Outcomes were self-care self-efficacy, readiness, and health locus of control (Internal, Chance, Powerful Others), examined as a summary HBCM score (average of standardized means) and individually. Analyses adjusted for pre-visit values of the dependent variables. Results Patients visiting SEE IT-trained physicians had higher summary HBCM scores (+0.42, 95% CI 0.07–0.77; p = 0.021). They also had greater self-care readiness (AOR 3.04, 95% CI 1.02–9.03, p = 0.046) and less Chance health locus of control (−0.27 points, 95% CI −0.50–0.04, p = 0.023), with no significant differences in other HBCMs versus controls. Conclusion Improvement in psychological HBCMs occurred among patients visiting SEE IT-trained physicians, Practice implications If further research shows the observed HBCM effects improve health behaviors and outcomes, SEE IT training might be offered widely to physicians.

Individuals who exercise are at lower risk for breast cancer and have better post-diagnosis outcomes. The biological mechanisms behind this association are unclear, but DNA methylation has been suggested.We developed a composite measure of DNA methylation across 45 CpG sites on genes selected a priori. We examined the association of this measure to self-reported physical activity and objectively measured cardiovascular fitness in a sample of healthy nonsmoking adults (n = 64) in an exercise promotion intervention.Individuals who were more physically fit and who exercised more minutes per week had lower levels of DNA methylation. Those who increased their minutes of physical activity over 12 months experienced decreases in DNA methylation.DNA methylation may be a mechanism linking exercise and cancer incidence and could serve as a biomarker for behavioral intervention trials. Studies with larger samples, objectively measured exercise, and more cancer-related markers are needed.

A transdisciplinary approach incorporating biological, psychological, behavioral, and genetic factors was taken to better identify proposed moderators of the effectiveness of an intervention to increase physical activity. This paper illustrates how theory-based individual difference variables can be integrated into a complex randomized controlled trial. The transdisciplinary framework guiding the selection of moderators, the COSTRIDE intervention study and sample, and the relationships among baseline variables are provided. Participants were non-active individuals randomly assigned to either the STRIDE exercise or health-and-wellness contact control condition. Structural equation modeling was utilized to demonstrate that relationships among baseline variables confirm hypothesized relationships in the transdisciplinary framework. Preliminary data from COSTRIDE suggest that interventions among sedentary individuals may be more effective if a broader range of factors influencing physical activity are considered.

Objective The purpose of this study was to investigate smokers' thoughts and worries about their smoking behavior. Researchers have sometimes asked smokers to make such self-assessments but typically using retrospective summary judgments. Design Using ecological momentary assessment, community and student smokers reported five times daily during two separate 1-week intervals. Main outcome measures Smokers reported their thoughts about smoking, worries about smoking, and level of contemplation to quit smoking. Results Smokers reported thinking negatively about their smoking 26.8% of the time they had a cigarette. The most frequent thoughts reported by smokers related to immediate reinforcement of smoking (e.g., "How I smell like cigarettes"). However, smokers reported more intense worry about thoughts related to health concerns (e.g., "Symptoms I'm having because of smoking"). The occurrence of negative thoughts was significantly and positively related to contemplation about quitting, worry about smoking, and risk perceptions. Finally, self-reported worry intensity was more strongly related to contemplation of quitting than negative thought occurrence. Conclusion Our results show that thoughts about smoking (i.e., cognitions) and feelings about smoking (i.e., worry) are loosely connected and it is feelings rather than cognitions that are most related to contemplation to quit.

Although much research on graphic cigarette warnings has focused on motivational responses, little focus has been given to how much individuals learn from these labels. This study aims to investigate whether graphic warnings provide greater perceived new knowledge of smoking consequences compared to text-only warnings, and to test a mediational model whereby perceived new knowledge promotes discouragement from smoking through its impact on worry. In two studies, young adult smokers and nonsmokers (ages 18–25) evaluated graphic + text and corresponding text-only labels on perceived knowledge, worry about the harms addressed by the warning, and discouragement from smoking. Compared to text-only labels, graphic + text labels were rated as providing better understanding, more new knowledge, and being more worrisome and discouraging. Perceived new knowledge predicted greater discouragement from smoking directly and through worry. Graphic warnings may be more efficacious than text-based warnings in increasing knowledge and worry about harms, and discouragement from smoking.

BackgroundEarly hypertension control reduces the risk of cardiovascular complications among patients with diabetes mellitus. There is a need to improve hypertension management among patients with diabetes mellitus.ObjectiveWe aimed to evaluate rates and associations of hypertension diagnosis and treatment among patients with diabetes mellitus and incident hypertension.DesignThis was a 4-year retrospective analysis of electronic health records.ParticipantsAdults ≥ 18 years old (n = 771) with diabetes mellitus, who met criteria for incident hypertension and received primary care at a large, Midwestern academic group practice from 2008 to 2011 were includedMain measuresCut-points of 130/80 and 140/90 mmHg were used to identify incident cases of hypertension. Kaplan-Meier analysis estimated the probability of receiving: 1) an initial hypertension diagnosis and 2) antihypertensive medication at specific time points. Cox proportional-hazard frailty models (HR; 95 % CI) were fit to identify associations of time to hypertension diagnosis and treatment.Key resultsAmong patients with diabetes mellitus who met clinical criteria for hypertension, 41 % received a diagnosis and 37 % received medication using the 130/80 mmHg cut-point. At the 140/90 mmHg cut-point, 52 % received a diagnosis and 49 % received medication. Atrial fibrillation (HR 2.18; 1.21-4.67) was associated with faster diagnosis rates; peripheral vascular disease (HR 0.18; 0.04-0.74) and fewer primary care visits (HR 0.93; 0.88-0.98) were associated with slower diagnosis rates. Atrial fibrillation (HR 3.07; 1.39-6.74) and ischemic heart disease/congestive heart failure (HR 2.16; 1.24-3.76) were associated with faster treatment rates; peripheral vascular disease (HR 0.16; 0.04-0.64) and fewer visits (HR 0.93; 0.88-0.98) predicted slower medication initiation. Diagnosis and treatment of incident hypertension were similar using cut-points of 130/80 and 140/90 mmHg.ConclusionsAmong patients with diabetes mellitus, even using a cut-point of 140/90 mmHg, approximately 50 % remained undiagnosed and untreated for hypertension. Future interventions should target patients with multiple comorbidities to improve hypertension and diabetes clinical care.

Background: The majority of health care utilization decisions in the United States are made by persons with multiple chronic conditions. Existing public reports of health system quality do not distinguish care for these persons and are often not used by the consumers they aim to reach. Objective: Our goal was to determine if tailoring quality reports to persons with diabetes mellitus and co-occurring chronic conditions would increase user engagement with a website that publicly reports the quality of diabetes care. Methods: We adapted an existing consumer-focused public reporting website using adult learning theory to display diabetes quality reports tailored to the user’s chronic condition profile. We conducted in-depth cognitive interviews with 20 individuals who either had diabetes and/or cared for someone with diabetes to assess the website. Interviews were audiotaped and transcribed, then analyzed using thematic content analysis. Results: Three themes emerged that suggested increased engagement from tailoring the site to a user’s chronic conditions: ability to interact, relevance, and feeling empowered to act. Conclusions: We conclude that tailoring can be used to improve public reporting sites for individuals with chronic conditions, ultimately allowing consumers to make more informed health care decisions.

Using ecological momentary assessment (EMA), we sought to determine whether differences in reporting would exist for smokers who self-monitored their smoking-related negative thoughts five times daily in comparison to a non-EMA control group. One hundred and seventeen smokers were randomly assigned to two conditions. Eighty-eight smokers carried personal digital assistants (PDAs) for two weeks and monitored negative thoughts each day and 29 smokers did not self-monitor their negative thoughts. All smokers completed pretest and posttest assessments reporting their perceived risk and worry associated with smoking consequences. The data revealed evidence of self-monitoring effects, as smokers in the EMA condition reported less worry after two weeks of self-monitoring compared to smokers in the control condition. The two conditions did not differ in their reports of perceived risk of smoking consequences. These data suggest that EMA procedures asking respondents to self-monitor their thoughts about smoking may influence feelings about their smoking behavior.

Background:Maximal oxygen uptake (VO2max), an assessment of cardiorespiratory fitness, is regularly used as the primary outcome in exercise interventions. Many criteria have been suggested for validating such tests—most commonly, a plateau in oxygen consumption. The current study investigated the proportion of inactive individuals who reached a plateau in oxygen uptake and who achieved a valid test as assessed by secondary criteria (RERmax ≥ 1.1; RPEmax ≥ 18; age predicted HRmax ±10bpm), and the correlates of a successful plateau or achievement of secondary criteria during a VO2max session.Methods:Participants (n = 240) were inactive individuals who completed VO2max assessments using an incremental treadmill test. We explored physical, behavioral, and motivational factors as predictors of meeting criteria for meeting a valid test.Results:Approximately 59% of the sample achieved plateau using absolute (increase of VO2 of 150ml O2 or less) and 37% achieved plateau using relative (increase of VO2 of 1.5ml/kg O2 or less) criteria. Being male, having a higher BMI, a greater waist-to-hip ratio, and increased self-efficacy were associated with lower odds of achieving an absolute plateau, whereas none of these factors predicted odds of achieving relative plateau.Conclusion:Findings raise questions about the validity of commonly used criteria with less active populations.

Research concerning motives for smoking cessation has focused on beliefs (cognitions) that people have, especially risk perceptions, with less attention directed to worry (negative affect) concerning one's smoking.We tested a manipulation to encourage smokers to think and worry more about their smoking behavior. We contrasted risk perceptions and worry as predictors of contemplation to quit smoking.Smokers were randomly assigned to two conditions in which they carried personal digital assistants for 2 weeks. When signaled, smokers read smoking consequence statements or daily hassle statements.After 2 weeks, experimental smokers reported greater perceived risk and worry about developing a medical condition compared to control smokers. Both perceived risk and worry independently mediated the relationship between the experimental manipulation and increased contemplation to quit smoking; however, worry was the strongest mediator in a multiple mediation model.Worry may be foremost for motivating smokers to attempt quitting.

Objective: Accurate measurement of beliefs about risk probability is essential to determine what role these beliefs have in health behavior. This study investigated the ability of several types of risk perception measures and of other constructs from health behavior theories to predict influenza vaccination. Design: Prospective study in which students, faculty, and staff at 3 universities (N 428) were interviewed in the fall, before influenza vaccine was available, and again early in the next calendar year. Main Outcome Measure: Self-reported influenza vaccination. Results: Two interview questions that asked about feeling at risk and feeling vulnerable predicted subsequent behavior better (r .44, p .001) than 2 questions that asked for agreement or disagreement with statements about risk probability (r .25, p .001) or 4 questions that asked respondents to estimate the magnitude of the risk probability (r .30, p .001). Of the 4 perceived risk magnitude scales, a 7-point verbal scale was the best predictor of behavior. Anticipated regret was the strongest predictor of vaccination (r .45, p .001) of all constructs studied, including risk perceptions, worry, and perceived vaccine effectiveness. Conclusion: Risk perceptions predicted subsequent vaccination. However, perceived risk phrased in terms of feelings rather than as a purely cognitive probability judgment predicted better. Because neither feeling at risk nor anticipated regret is represented in the most commonly used theories of health behavior, the data suggest that these theories are missing important constructs.

Between 1980 and 1991, 13 of 1312 carotid artery reconstructions were performed for aneurysms of the extracranial internal carotid artery. The patients included 12 men and one woman, mean age 56 years. Postoperative aneurysms and aneurysms involving the common carotid artery were excluded from the study. In six cases, the upper part of the aneurysm was higher than a line joining the mandibular to the tip of the mastoid process. Six aneurysms were atherosclerotic, two post-traumatic, four dysplasic and one post-traumatic and atherosclerotic. Nine patients had focal neurological symptoms (seven hemispherical, two ocular), one presented with cranial nerve compression, two had non-hemispherical symptoms and one was symptom-free. Surgical reconstruction was achieved by 12 venous grafts and one aneurysmorrhaphy. A conventional cervical approach was used in seven cases; in four cases subluxation of the mandible with resection of the posterior belly of the digastric muscle and division of the styloid process and its attached muscles was used. An infratemporal approach with release of the 7th nerve and opening up of the first portion of the carotid canal was used in two patients. There were no deaths or strokes but two patients had a transient ischaemic attack. In four cases, a cranial nerve palsy developed; one involving the 9th nerve did not recover. Patency was assessed by postoperative angiography in all cases. Mean (range) follow-up was 46 (4-126) months. One patient died after 2 years as a result of myocardial infarction. One patient had a transient ischaemic attack during the 2nd postoperative year. All survivors were assessed in January 1992, when all reconstructed arteries were patent.

Ten patients (eight men, two women) who underwent surgical reconstruction of the superior vena cava using an expanded polytretrafluoroethylene (ePTFE) prosthesis between 1981 and 1991 were reviewed to assess the therapeutic value of such surgery. The mean (s.d.) age was 55(12) years. Obstruction of the superior vena cava was caused by pulmonary or mediastinal cancer in nine patients and chronic mediastinitis in one. Eight patients had superior vena cava syndrome and two had symptoms of lung disease. The diagnosis of superior vena cava obstruction was made before surgery by computed tomography or superior venacavography in eight patients and during the surgical procedure in two. Tumour resection was performed in five patients. Venous reconstruction was achieved by interposition of an ePTFE graft between the proximal and distal end of the vena cava in three patients and between one (four cases) or two (three cases) tributaries of the superior vena cava and the right atrium in seven. No patient died during the perioperative period. Symptoms of superior vena cava obstruction disappeared promptly after operation in all patients. Postoperative patency was assessed by cavography or computed tomography; all the grafts were patent. During follow-up no patients presented with recurrent superior vena cava syndrome. Eight patients died. The cumulative survival rates were 70, 25 and 12.5% at 1, 2 and 5 years, respectively. Surgical reconstruction of the superior vena cava with an ePTFE prosthesis provided immediate and long-term relief of symptoms of superior vena cava obstruction with a low surgical morbidity, even in patients with unresectable malignancy.

From July 1990 to July 1993, we performed 41 percutaneous intra-arterial thrombolysis procedures for the treatment of obstructed infra-inguinal bypass grafts in 32 patients. There were 27 men and five women with a mean age of 63 +/- 17 years (range 21 to 83 years). The symptoms of occlusion were intermittent claudication in three cases, rest pain in 12 cases, severe ischemia without sensitive-motor loss in 26 cases. Bypasses were achieved using a prosthesis in 18 cases (43.9%), a saphenous vein in 10 cases (24.4%), an arterial allograft in nine cases (21.9%), and a composite prosthesis-vein graft in four cases (9.8%) (table I). The distal anastomosis of the bypass graft was located on the popliteal artery in 26 cases (63.4%) and a crural artery in 15 cases (36.6%). The mean duration of the occlusion was 4.9 +/- 3.4 days (range 1 to 15 days). The percutaneous approach was through the contralateral common femoral artery in 26 cases (63.4%), through the ipsilateral common femoral artery in seven cases (17.1%), through the left humeral artery in eight cases (19.5%). In all cases the thrombolytic agent was the recombinant tissue-type plasminogen activator (rt-PA). Each procedure began with the injection of a five milligram bolus of rt-PA into or onto the thrombus followed by infusion of rt-PA into the thrombus at a dose of 0.05 mg/kg/h. Intravenous heparin was simultaneously administered. Serum fibrinogen, prothrombin time, and partial thromboplastin time (PTT) were measured every three hours.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1980 and January 1985, 462 consecutive patients underwent lung resection for bronchogenic carcinoma. Eighty of these patients (17.3 percent) had atherosclerosis involving mainly the coronary arteries (40 percent). The mortality rate was significantly higher in patients with atherosclerosis (10 percent) than in those without it (4.7 percent), but the long-term survival was not affected with the presence of atherosclerosis. The lung carcinoma-atherosclerosis association raises two problems: what investigations should be carried out in this group of patients at risk, and what treatment should be given priority when vascular lesions are present and likely to become complicated by pulmonary surgery? However, the presence of atherosclerosis should not lead to a re-evaluation of the need for lung resection.

Internal carotid aneurysms at the base of the skull after blunt trauma are infrequent but their management is difficult, leading many surgeons to only attempt ligation. We report 2 cases presenting with high traumatic aneurysms, following motorcycle accidents. The 2 aneurysms underwent repair by a venous graft. The petrous portion of the carotid artery was approached and controlled by an ENT surgeon. This "infratemporal" approach was used exposing the facial nerve, combined with temporary anterior sub-luxation of the temporomaxillary joint to expose the lower part of the carotid canal which was opened up with a drill in order to control the carotid artery in the petrous canal. Both patients developed facial nerve palsies which improved within 3 months. Postoperative angiography showed patent vein grafts and the patients were doing well, without any symptoms 18 and 24 months later.

Between March 1982 and December 1987, 112 patients with oesophageal cancer were treated by gastroplasty following oesophagectomy to restore gastrointestinal continuity. This technique was used in all oesophageal cancers regardless of their site, with the exception of paryngo-oesophageal and oesophago-cardio-fundal cancers. The overall mortality of 12.5% fell to below 6% during the last two years. The postoperative course was straightforward in 54.5% of cases. The most frequent complications were respiratory tract complications (19 cases of ARDS out of 112 patients, i.e. 17%) and fistulae at the oesophago-gastric anastomosis (9 cases out of 112, i.e. 8%). The secondary complications were dominated by anastomotic stenoses (19/98, i.e. 19.3%).

Background The purpose of this research was to replicate a successful intervention to increase physical activity in a different region of the country, and explore genetic and physiological moderators of intervention efficacy drawn from a transdisciplinary theoretical framework. Method A randomized controlled trial comparing a print-based physical activity intervention (COSTRIDE) to a print-based health and wellness contact control (HW) intervention was conducted. Sedentary participants (n = 219) completed assessments at baseline and follow-up assessments at 3, 6, 9, and 12 months following the initiation of the intervention. Results Participants in both conditions significantly increased exercise behavior in the first six months, and then leveled off or decreased physical activity in the second six months of the study. Those in the COSTRIDE intervention increased significantly more than those in the HW intervention, and were better able to maintain their exercise behavior. Genetic factors (BDNF, rs6265; FTO, rs8044769), but not selected physiological (body temperature, blood lactate, systolic blood pressure, plasma norepinephrine, and heart rate) or subjective (perceived pain, affect) responses to physical activity, moderated response to the intervention. Conclusions There are underlying genetic factors that influence response to behavioral intervention, and a better understanding of these factors has the potential to influence the development, targeting and tailoring of behavioral interventions to increase physical activity.
