Abstract
BACKGROUND Addressing disparities in blood pressure control must include supporting antihypertensive medication adherence (MA). Developing effective MA interventions requires identifying the most important factors influencing MA. OBJECTIVE In this review, the authors aimed to meta-analyze the results of research testing associations between factors potentially influencing antihypertensive MA and assessed antihypertensive MA in historically underrepresented populations. Additional exploratory analyses focused on system-level factors, which have been understudied and may particularly impact disparities in MA. METHODS A health sciences librarian assisted with searching across 10 databases. Inclusion criteria included (1) published in English, (2) sample of adults with hypertension, (3) ≥50% of participants having self-identified as a race/ethnicity underrepresented in the country where the study was conducted, and (4) reporting sufficient data to calculate effect size(s). RESULTS Fifty-eight studies were eligible for inclusion. Nine factors met criteria for planned analyses. Older age (r = 0.08, P < .01; k = 26 studies) and higher income (r = 0.11, P = .01; k = 15) were significantly correlated with better MA. Having depressive symptoms was significantly correlated with worse MA (r = -0.18, P < .01; k = 11). Effect sizes for sex, education level, marital status, number of medications, comorbidities, and perceived social support were not significant. System-level factors examined included insurance coverage, access to healthcare, perceived barriers, having a primary care provider, perceptions of their healthcare provider, and experiences of discrimination in healthcare. CONCLUSIONS Understanding the impact of factors associated with antihypertensive MA in historically underrepresented adults can support development of targeted, culturally relevant MA interventions. Future research should examine the impact of system-level factors on antihypertensive MA among historically underrepresented populations.

Abstract
BACKGROUND Ketogenic therapies have shown benefit for seizure reduction in epilepsy but their impact on other neurologic conditions is less known. In this literature review, the efficacy of ketogenic therapies were assessed in Parkinson's disease (PD), Alzheimer's disease (AD), and mild cognitive impairment (MCI). METHODS A literature search was conducted using PubMed, Scopus, and Google Scholar focusing on ketogenic therapies in PD, AD, and MCI. RESULTS A total of 2565 records were identified with a total of 15 studies (3 for PD and 12 for MCI/AD) meeting criteria for analysis. The ketogenic diet was used in all the PD studies and did show significant improvement in motor function either through vocal quality, gait, freezing, tremor, and/or balance. A variety of ketogenic therapies were utilized in the MCI and AD groups including a ketogenic diet, low-carbohydrate diet, modified Adkins diet, Mediterranean diet with coconut oil supplementation, a ketogenic diet with a ketogenic medium chain triglyceride (kMCT) supplement, as well as ketogenic supplements including a ketogenic drink with kMCT, oral ketogenic compounds (Axona and AC-1202), and MCT oil or emulsion. The ketogenic diet independently showed a non-significant trend towards improvement in cognition. The Mediterranean diet, modified Adkins diet, and low-carbohydrate diet showed statistically significant improvements in some, although not all, of their cognitive measures. Use of ketogenic supplements, drinks, or compounds showed variable results in the AD and MCI groups. The Axona and AC-1202 compounds showed no significant improvement in cognition at the end of their respective 90-day trials. Most MCT supplements did show cognitive improvements, although only after 6 months of adherence. Adherence to the intervention was problematic in most of the diet studies. CONCLUSION Ketogenic therapies have promise in PD, AD, and MCI for symptom improvement although larger studies are needed to support their implementation in clinical practice.

Abstract
PURPOSE Before the COVID-19 pandemic and the disruptions it brought, medication adherence was already a challenging and complex health behavior. The purpose of this study was to describe patients' interactions in clinic, pharmacy, and home contexts and associated medication management and adherence during the early phase of the COVID-19 pandemic. PATIENTS AND METHODS A survey questionnaire was developed using the Medication Adherence Context and Outcomes framework and distributed via social media between May and July 2020 targeting adults taking a daily prescribed medication. Survey questions assessed sociodemographics, interactions with healthcare providers, clinics, pharmacies, medication management experiences, habit strength, and life chaos perceptions during the pandemic. Medication adherence was assessed by the self-report BAASIS© scale to measure implementation, discontinuation, and overall nonadherence. RESULTS A total of 134 adults from the United States, mean age 50.0 (SD 16.1) years were included in this analysis. Respondents took a median of 3.50 (interquartile range 4) daily medications. Delays in seeing a provider were reported by 47 (35.1%). Pharmacy encounters were impacted; 25 (18.7%) indicated their method for obtaining medication changed. Medication nonadherence was reported among 62 (46.3%) and was significantly greater among those who delayed prescription refills (p=0.032), pillbox users (p=0.047), and those who experienced greater life chaos (p=0.040) and lower habit strength (p<0.001) in the early phase of the pandemic. CONCLUSION Although the early phase of the pandemic affected access to care for nearly one-third of the sample, distance-accessible care options and strategies to obtain needed services without being in-person supported respondents medication management. Helpful strategies included provider accessibility, telehealth, home delivery/mail-order, drive-thru's, 90-day supplies, and online/automatic refills. Methods to develop and reestablish habits are critical. Care providers in clinic and pharmacy settings can educate and remind patients about services like distance-accessible technologies and online ordering of medications and establishing routines to support medication adherence.

Abstract
Poor medication adherence is a significant problem, yet interventions to improve it have been largely ineffective. Existing ecological models indicate that adherence is multi-dimensional; however, they do not reflect understanding of context-specific processes and how they lead to adherence outcomes. A framework that reflects context-specific processes is important because it could be used to inform context-specific intervention delivery and measure associated adherence outcomes. The purpose of this paper is to describe the Medication Adherence Context and Outcomes (MACO) framework, which includes contexts (ie, clinics, pharmacies, and home) and context-specific processes (ie, shared decision-making, prescription filling strategies, home medication management) that lead to adherence outcomes (initiation, implementation, discontinuation, and persistence). The Medication and Adherence Contexts and Outcomes (MACO) framework was iteratively developed between 2015 and 2018 based on theory, practice, and research and combining patient experience journey mapping to chronologically describe the environmental contexts and actions (processes) that occur within the contexts and how they contribute to medication adherence as outcome. The three distinct yet interrelated contexts described in the MACO framework are 1) clinical encounters, 2) pharmacy encounters, and 3) day-to-day home management. Within these contexts are specific medication management actions that occur (processes) in order to produce adherence-related outcomes (initiation, implementation, and discontinuation/persistence). The MACO framework distinguishes context-specific processes and outcomes. The MACO framework may be useful to understand at which point(s) along the continuum people experience problems with managing medications. This understanding is potentially useful for developing and delivering context-specific interventions that are based on processes that underlie nonadherence and selecting adherence measures appropriate for the contexts.

Abstract
OBJECTIVE The purpose of this review was to identify and describe physical activity (PA) interventions that have been implemented with American Indian and Alaska Natives (AIANs) in the U.S. and Canada since 2006. DATA SOURCE Searches were conducted in 8 databases plus grey literature sources. STUDY INCLUSION AND EXCLUSION CRITERIA Eligible studies: (a) described an intervention designed to increase PA; (b) targeted AIANs residing in the U.S. or Canada, or if a multiethnic population, contained an AIAN subanalysis; (c) were published in 2006 or later; and (d) reported a PA outcome. DATA EXTRACTION Two reviewers independently extracted data, with conflicts resolved through discussion. DATA SYNTHESIS Data were synthesized by participant characteristics, intervention strategies, PA outcomes, and impact. RESULTS We identified 25 eligible studies, most targeting children and youth. Intergenerational, environmental policy, cultural adaptation, and curriculum-based approaches were used. Twenty studies used self-reported PA measures. 80% of studies used an element of cultural adaptation, mostly considering cultural needs in design, not program or outcome evaluation. Sedentary behavior and leisure-time PA were rarely assessed. Significant changes in PA outcomes were achieved post-intervention in 13 studies (52%). CONCLUSION Future interventions should target AIAN adults to evaluate sedentary behavior and leisure-time PA. Interventions should incorporate psychometrically tested objective measures and prioritize the Native perspective from intervention design through project evaluation.

Abstract
Adverse childhood experiences (ACEs) are associated with poor treatment adherence and worse health outcomes among adults, but evidence among adolescents is less clear. The current systematic review identified and synthesized results from studies examining associations between ACEs and treatment adherence among adolescents. An expert medical librarian conducted searches in seven databases. Results were analyzed using a narrative synthesis framework. A total of six studies were eligible for review. Assessment strategies for ACEs and treatment adherence varied across studies. Most studies assessed for histories of maltreatment and neglect. Treatment adherence was most often defined as some form of attendance in a treatment program. Results support a relationship between ACEs and treatment nonadherence in adolescents. ACEs related to maltreatment, particularly emotional abuse, may be more predictive of treatment nonadherence than other types of ACEs. Specific qualities of ACEs (e.g., timing, intensity, frequency) may influence the relationship between ACEs and treatment nonadherence.

Abstract
BACKGROUND/OBJECTIVE As pharmacists work to ensure reimbursement for chronic disease management services on the national level, evidence of their impact on important health metrics, such as medication adherence, is needed. However, summative evidence is lacking on the effectiveness of pharmacists to improve medication adherence in older adults. The objective was to assess the effectiveness of pharmacist-led interventions on medication adherence in older adults (65+ years). DESIGN/SETTING/PARTICIPANTS Using a systematic review and meta-analytic approach, a comprehensive search of publications in PubMed, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Google Scholar was conducted through April 2, 2020 for randomized clinical trials of pharmacist-led interventions to improve medication adherence in older adults. A standardized mean difference effect size (Cohen's d) was calculated for medication adherence in each study. Study effect sizes were pooled using a random-effects model, with effect sizes weighted by inverse of its total variance. MEASUREMENTS Medication adherence using any method of measurement. RESULTS Among 40 unique randomized trials of pharmacist-led interventions with data from 8822 unique patients (mean age, range: 65-85 years), the mean effect size was 0.57 (k = 40; 95% Confidence Interval [CI]: 0.38-0.76). When two outlier studies were excluded from the analysis, the mean effect size reduced to 0.41 (k = 38; 95% CI: 0.27-0.54). A sensitivity analysis of medication adherence outcome by time point resulted in a mean effect size of 0.64 at 3 months (k = 12; 95% CI: 0.32-0.97), 0.30 at 6 months (k = 13; 95% CI: 0.11-0.48), 0.22 at 12 months (k = 12; 95% CI: 0.08-0.37), and 0.36 for outcome time points beyond 12 months (k = 5; 95% CI: 0.02-0.70). CONCLUSION This meta-analysis found a significant improvement in medication adherence among older adults receiving pharmacist-led interventions. Implementation of pharmacist-led interventions supported by Medicare reimbursement could ensure older adults' access to effective medication adherence support.

Abstract
Hypertension is a chronic condition that disproportionately affects African Americans. Managing high blood pressure (HBP) requires adherence to daily medication. However, many patients with hypertension take their HBP medication inconsistently, putting them at heightened risk of heart disease. Researchers have shown that these health risks are greater for African Americans than for Caucasians. In this article, we examine barriers and facilitators of medication adherence among urban African Americans with hypertension. We interviewed 24 African Americans with hypertension (58.5% women, average age 59.5 years) and conducted a comprehensive thematic analysis. Twenty-two barriers and 32 facilitators to medication adherence emerged. Barriers included side effects and forgetting while facilitators included reminders, routines, and social support. Using this data, we developed a diagram of theme connectedness of factors that affect medication adherence. This diagram can guide multi-level HBP intervention research that targets African Americans to promote medication adherence, prevent heart disease, and reduce ethnic and racial health disparities.

Abstract
PURPOSE Medication nonadherence is a significant and multidimensional problem contributing to an increased risk of morbidity and mortality. Inconveniences in pharmacy and home contexts may increase nonadherence. This research examined inconveniences in pharmacy and home contexts associated with self-reported nonadherence, controlling for demographic and medication-taking covariates. METHODS Data from 4682 individuals who reported self-managing medications in an online marketing survey between October and December 2017 were analyzed in this secondary analysis. Nonadherence was dichotomized using a single question about likelihood to take medications as prescribed (adherence=always; nonadherence=most of the time, some of the time, never). Multivariable logistic regression with backwards elimination was used to examine the pharmacy (use of home delivery, number prescriptions picked up and visits to pharmacy) and home context (method used to organize/manage medications, satisfaction, and bother with management) variables and the demographic (age, sex, race/ethnicity, education, income, insurance) and medication (number of oral medications, medication changes and frequency of taking) covariates associated with nonadherence. RESULTS Overall, 25.8% of the responses indicated nonadherence. Nonadherence was more likely for individuals making fewer separate pharmacy trips (OR 0.98; 95% CI 0.97-0.99); picking up fewer prescriptions (OR 0.96; 95% CI 0.93-0.99); never, rarely or sometimes using mail order compared with always (OR 1.71; 95% CI 1.30-2.26); not satisfied with managing medications (OR 2.13; 95% CI 1.42-3.19); and using pill pouches and being bothered by them (OR 8.28; 95% CI 1.83-37.31). Using pill pouches or a pillbox and not being bothered by them significantly decreased nonadherence likelihood. Younger and female respondents and those reporting medication changes in the last year were also more likely to report nonadherence. CONCLUSION Though reasons for nonadherence are multidimensional, this study suggests that inconveniences in both the pharmacy and home context are important.

Abstract
AIM To synthesize and compare outcomes from controlled trials of interventions to improve heart failure self-care among adults. BACKGROUND Heart failure self-care interventions are recommended for preventing and detecting exacerbations, improving symptom management and preventing hospitalizations. Little is known about the overall effectiveness of heart failure self-care programmes and which types of interventions show the greatest improvement in outcomes. DESIGN Systematic review and meta-analysis, including moderator analyses. METHODS Multiple databases (including MEDLINE/PubMed, CINAHL, PsycINFO, Scopus and Cochrane Central Register of Controlled Trials) will be searched from inception through 2018 along with grey literature searches to identify trials testing interventions to improve self-care outcomes of adults with heart failure. Data will be extracted from eligible studies on sample, methodological and intervention characteristics and data to calculate effect sizes. Data will be analysed using random-effects models. Moderator variables will be analysed with meta-regression and sub-group analyses. Risk for bias will be assessed using the Cochrane Risk for Bias tool and by examining potential sources of bias as moderator variables. Funding for this project began in July 2017. DISCUSSION We will analyse self-care behaviour outcomes and clinical outcomes including hospitalizations, mortality, disease severity and quality of life. This will be the most extensive meta-analysis of heart failure self-care interventions to date. IMPACT Comparative effectiveness of existing self-care interventions is not yet known. This research will identify the most promising self-care intervention components for designing better interventions and guide targeting of interventions to specific sub-populations.

Abstract
This systematic review applied meta-analytic procedures to integrate primary research that examined blood pressure outcomes of medication adherence interventions. Random-effects model analysis calculated standardized mean difference effect sizes. Exploratory dichotomous and continuous moderator analyses using meta-analytic analogues of ANOVA and regression were performed. Codable data were extracted from 156 reports with 60,876 participants. The overall weighted mean difference systolic effect size was 0.235 across 161 treatment versus control comparisons. The diastolic effect size was 0.189 from 181 comparisons. Effect sizes were significantly heterogeneous. Common risks of bias included lack of allocation concealment, unmasked data collectors, and absent intention-to-treat analyses. Exploratory moderator analyses suggested that habit-based interventions may be most effective. The largest effect sizes were for interventions delivered by pharmacists. The modest magnitude effect sizes suggest future research should explore novel higher dose interventions that might address multiple levels of influence on adherence behavior.

Abstract
BACKGROUND Despite the known benefits of medication therapy for secondary prevention of coronary artery disease (CAD), many patients do not adhere to prescribed medication regimens. Medication nonadherence is associated with poor health outcomes and higher healthcare cost. OBJECTIVE The purpose of this meta-analysis was to determine the overall effectiveness of interventions designed to improve medication adherence (MA) among adults with CAD. In addition, sample, study design, and intervention characteristics were explored as potential moderators to intervention effectiveness. METHODS Comprehensive search strategies helped in facilitating the identification of 2-group, treatment-versus-control-design studies testing MA interventions among patients with CAD. Data were independently extracted by 2 trained research specialists. Standardized mean difference effect sizes were calculated for eligible primary studies, adjusted for bias, and then synthesized under a random-effects model. Homogeneity of variance was explored using a conventional heterogeneity statistic. Exploratory moderator analyses were conducted using meta-analytic analogs for analysis of variance and regression for dichotomous and continuous moderators, respectively. RESULTS Twenty-four primary studies were included in this meta-analysis. The overall effect size of MA interventions, calculated from 18,839 participants, was 0.229 (P < .001). The most effective interventions used nurses as interventionists, initiated interventions in the inpatient setting, and informed providers of patients' MA behaviors. Medication adherence interventions tested among older patients were more effective than those among younger patients. The interventions were equally effective regardless of number of intervention sessions, targeting MA behavior alone or with other behaviors, and the use of written instructions only. CONCLUSIONS Interventions to increase MA among patients with CAD were modestly effective. Nurses can be instrumental in improving MA among these patients. Future research is needed to investigate nurse-delivered MA interventions across varied clinical settings. In addition, more research testing MA interventions among younger populations and more racially diverse groups is needed.

Abstract
BACKGROUND Poor adherence to medications is a significant problem that leads to increased morbidity, mortality, and health care costs. Recommended approaches to address medication adherence vary, and existing practice guidelines are unclear. PURPOSE This review evaluated clinical practice guidelines designed to help health care providers address patients' medication adherence. METHOD Multiple search methods were used to identify national or international guidelines addressing medication adherence. We included guidelines published in English, as well as guidelines with an English-language summary or translation. RESULTS We identified 23 guidelines of varying detail and quality. Recommendations were categorized as assessment strategies (n = 20 guidelines); educational strategies (n = 18); behavioral strategies (n = 17); therapeutic relationship, communication, and provider factors (n = 19); and addressing outside influences/co-morbidities (n = 10). CONCLUSION Future guidelines should be more clearly guided by research findings and comparative effectiveness methods. When implemented, guidelines will facilitate health care providers and health systems in supporting optimal adherence and improved health outcomes.

Abstract
BACKGROUND Poor adherence to medications is a common problem among heart failure (HF) patients. Inadequate adherence leads to increased HF exacerbations, reduced physical function, and higher risk for hospital admission and death. Many interventions have been tested to improve adherence to HF medications, but the overall impact of such interventions on readmissions and mortality is unknown. METHODS AND RESULTS We conducted a comprehensive search and systematic review of intervention studies testing interventions to improve adherence to HF medications. Mortality and readmission outcome effect sizes (ESs) were calculated from the reported data. ESs were combined using random-effects model meta-analysis methods, because differences in true between-study effects were expected from variation in study populations and interventions. ES differences attributed to study design, sample, and intervention characteristics were assessed using moderator analyses when sufficient data were available. We assessed publication bias using funnel plots. Comprehensive searches yielded 6665 individual citations, which ultimately yielded 57 eligible studies. Overall, medication adherence interventions were found to significantly reduce mortality risk among HF patients (relative risk, 0.89; 95% CI, 0.81, 0.99), and decrease the odds for hospital readmission (odds ratio, 0.79; 95% CI, 0.71, 0.89). Heterogeneity was low. Moderator analyses did not detect differences in ES from common sources of potential study bias. CONCLUSIONS Interventions to improve medication adherence among HF patients have significant effects on reducing readmissions and decreasing mortality. Medication adherence should be addressed in regular follow-up visits with HF patients, and interventions to improve adherence should be a key part of HF self-care programs.

Abstract
OBJECTIVE This systematic review applied meta-analytic procedures to integrate primary research that examined theory- or model-linked medication adherence interventions. METHODS Extensive literature searching strategies were used to locate trials testing interventions with medication adherence behavior outcomes measured by electronic event monitoring, pharmacy refills, pill counts, and self-reports. Random-effects model analysis was used to calculate standardized mean difference effect sizes for medication adherence outcomes. RESULTS Codable data were extracted from 146 comparisons with 19,348 participants. The most common theories and models were social cognitive theory and motivational interviewing. The overall weighted effect size for all interventions comparing treatment and control participants was 0.294. The effect size for interventions based on single-theories was 0.323 and for multiple-theory interventions was 0.214. Effect sizes for individual theories and models ranged from 0.041 to 0.447. The largest effect sizes were for interventions based on the health belief model (0.477) and adult learning theory (0.443). The smallest effect sizes were for interventions based on PRECEDE (0.041) and self-regulation (0.118). CONCLUSION These findings suggest that theory- and model-linked interventions have a significant but modest effect on medication adherence outcomes.

Abstract
BACKGROUND Inadequate medication adherence is a pervasive, under-recognized cause of poor health outcomes. Many intervention trials designed to improve medication adherence have targeted adults with adherence problems. No previous reviews have synthesized the effectiveness of medication adherence interventions focused on subjects with medication adherence difficulties. OBJECTIVE This systematic review and meta-analysis synthesized findings from medication adherence intervention studies conducted among adults with medication adherence difficulties. METHODS Primary research studies were eligible for inclusion if they tested an intervention designed to increase medication adherence among adults with documented adherence difficulties and reported medication adherence behavior outcomes. Comprehensive search strategies of 13 computerized databases, author and ancestry searches, and hand searches of 57 journals were used to locate eligible primary research. Participant demographics, intervention characteristics, and methodological features were reliably coded from reports along with medication adherence outcomes. Effect sizes for outcomes were calculated as standardized mean differences, and random effects models were used to estimate overall mean effects. Exploratory dichotomous and continuous variable moderator analyses were employed to examine potential associations between medication adherence effect size and sample, intervention, and methodological characteristics. RESULTS Data were extracted from 53 reports of studies involving 8243 individual primary study participants. The overall standardized mean difference effect size for treatment vs. control subjects was 0.301. For treatment pre- vs. post-intervention comparisons, the overall effect size was 0.533. Significantly larger effect sizes were associated with interventions incorporating prompts to take medications than interventions lacking medication prompts (0.497 vs. 0.234). Larger effect sizes were also found for interventions that linked medication taking with existing habits compared to interventions that did not (0.574 vs. 0.222). Effect sizes were largest among studies that measured adherence by pill counts or electronic event monitoring systems. Analysis of study design features identified several potential risks of bias. Statistically significant publication bias was detected, but adherence effect sizes were not significantly associated with other risks of bias. CONCLUSIONS These findings document that interventions targeting individuals with medication adherence problems can have modest but significant effects on medication-taking behavior. The findings support the use of behavioral strategies such as prompts and linking medications to habits to increase medication adherence in adults with adherence challenges. Face-to-face interventions appear to be critical for patients who have experienced past problems with medication adherence.

Abstract
OBJECTIVE Using meta-analytic procedures to synthesize changes in patient-centered outcomes after medication adherence interventions. METHODS Strategies to locate studies included online searches of 13 databases and 19 research registries, hand searches of 57 journals, and author and ancestry searches of all eligible studies. Search terms included patient compliance, medication adherence, and related terms. Searches were conducted for all studies published since 1960. Eligible published or unpublished primary studies tested medication adherence interventions and reported medication knowledge, quality of life, physical function, and symptom outcomes. Primary study attributes and outcome data were reliably coded. Overall standardized mean differences (SMDs) were analyzed using random-effects models. Dichotomous and continuous moderator analyses and funnel plots were used to explore risks of bias. RESULTS Thorough searching located 141 eligible reports. The reports included 176 eligible comparisons between treatment and control subjects across 23,318 subjects. Synthesis across all comparisons yielded statistically significant SMDs for medication knowledge (d = 0.449), quality of life (d = 0.127), physical function (d = 0.142), and symptoms (d = 0.182). The overall SMDs for studies focusing on subsamples of patients with specific illnesses were more modest but also statistically significant. Of specific symptoms analyzed (depression, anxiety, pain, energy/vitality, cardiovascular, and respiratory), only anxiety failed to show a significant improvement after medication adherence interventions. Most SMDs were significantly heterogeneous, and risk of bias analyses suggested links between study quality and SMDs. CONCLUSIONS Modest but significant improvements in patient-centered outcomes were observed after medication adherence interventions.

Abstract
This systematic review applied meta-analytic procedures to synthesize medication adherence interventions that focus on adults with hypertension. Comprehensive searching located trials with medication adherence behavior outcomes. Study sample, design, intervention characteristics, and outcomes were coded. Random-effects models were used in calculating standardized mean difference effect sizes. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression to explore associations between effect sizes and sample, design, and intervention characteristics. Effect sizes were calculated for 112 eligible treatment-vs.-control group outcome comparisons of 34,272 subjects. The overall standardized mean difference effect size between treatment and control subjects was 0.300. Exploratory moderator analyses revealed interventions were most effective among female, older, and moderate- or high-income participants. The most promising intervention components were those linking adherence behavior with habits, giving adherence feedback to patients, self-monitoring of blood pressure, using pill boxes and other special packaging, and motivational interviewing. The most effective interventions employed multiple components and were delivered over many days. Future research should strive for minimizing risks of bias common in this literature, especially avoiding self-report adherence measures.

Abstract
OBJECTIVE This systematic review applied meta-analytic procedures to synthesise medication adherence (also termed compliance) interventions that focus on healthcare providers. DESIGN Comprehensive searching located studies testing interventions that targeted healthcare providers and reported patient medication adherence behaviour outcomes. Search strategies included 13 computerised databases, hand searches of 57 journals, and both author and ancestry searches. Study sample, intervention characteristics, design and outcomes were reliably coded. Standardised mean difference effect sizes were calculated using random-effects models. Heterogeneity was examined with Q and I(2) statistics. Exploratory moderator analyses used meta-analytic analogue of ANOVA and regression. RESULTS Codable data were extracted from 218 reports of 151,182 subjects. The mean difference effect size was 0.233. Effect sizes for individual interventions varied from 0.088 to 0.301. Interventions were more effective when they included multiple strategies. Risk of bias assessment documented larger effect sizes in studies with larger samples, studies that used true control groups (as compared with attention control), and studies without intention-to-treat analyses. CONCLUSION Overall, this meta-analysis documented that interventions targeted to healthcare providers significantly improved patient medication adherence. The modest overall effect size suggests that interventions addressing multiple levels of influence on medication adherence may be necessary to achieve therapeutic outcomes.

Abstract
Considerable research has tested physical activity (PA) interventions to prevent and treat overweight and obesity. This comprehensive meta-analysis synthesized the anthropometric effects of supervised exercise interventions and motivational interventions to increase PA. Eligible intervention studies included healthy participants with reported anthropometric outcomes [e.g., body mass index (BMI)]. Extensive searching located 54,642 potentially eligible studies. We included data from 535 supervised exercise and 283 motivational interventions in our syntheses, which used random-effects analyses. Exploratory moderator analyses used meta-analytic analogues of ANOVA and regression. We synthesized data from 20,494 participants in supervised exercise and 94,711 undergoing motivational interventions. The overall mean effect sizes (ES, d) for treatment versus control groups in supervised exercise interventions were 0.20 (treatment vs. control within-group comparison) and 0.22 (between-group comparison). The ES of 0.22 represents a post-intervention BMI of 26.7 kg/m(2) for treatment participants relative to 27.7 kg/m(2) for controls. The corresponding mean ES for motivational interventions was significantly smaller (d = 0.09 for between group, d = 0.10 for treatment vs. control within-group). Control group within-group comparisons revealed slightly worsening anthropometric outcomes during study participation (d = -0.03 to -0.04). Moderator analyses identified potential variables for future research. These findings document significant improvements in anthropometric effects from both supervised exercise and motivational interventions.

Abstract
This article describes cultural relevance in physical activity intervention research with underrepresented populations. Seventy-one extant studies which tested interventions to increase physical activity among underrepresented adults were included. Verbatim descriptions of efforts to enhance cultural relevance of study designs and interventions were extracted and then content analyzed. We found strategies to enhance cultural relevance of interventions as soliciting input from population members, linking intervention content with values, addressing language and literacy challenges, incorporating population media figures, using culturally relevant forms of physical activity, and addressing specific population linked barriers to activity. Methodological approaches included specialized recruitment and study locations, culturally relevant measures, underrepresented personnel, and cost-awareness study procedures to prevent fiscal barriers to participation. Most reported activities were surface matching. Existing research neither compared the effectiveness of cultural relevance approaches to standardized interventions nor addressed economic, education, geographic, or cultural heterogeneity among groups.

Abstract
OBJECTIVE Inadequate medication adherence is a widespread problem that contributes to increased chronic disease complications and health care expenditures. Packaging interventions using pill boxes and blister packs have been widely recommended to address the medication adherence issue. This meta-analysis review determined the overall effect of packaging interventions on medication adherence and health outcomes. In addition, we tested whether effects vary depending on intervention, sample, and design characteristics. RESEARCH DESIGN AND METHODS Extensive literature search strategies included examination of 13 computerized databases and 19 research registries, hand searches of 57 journals, and author and ancestry searches. Eligible studies included either pill boxes or blister packaging interventions to increase medication adherence. Primary study characteristics and outcomes were reliably coded. Random-effects analyses were used to calculate overall effect sizes and conduct moderator analyses. RESULTS Data were synthesized across 22,858 subjects from 52 reports. The overall mean weighted standardized difference effect size for two-group comparisons was 0.593 (favoring treatment over control), which is consistent with the mean of 71% adherence for treatment subjects compared to 63% among control subjects. We found using moderator analyses that interventions were most effective when they used blister packs and were delivered in pharmacies, while interventions were less effective when studies included older subjects and those with cognitive impairment. Methodological moderator analyses revealed significantly larger effect sizes in studies reporting continuous data outcomes instead of dichotomous results and in studies using pharmacy refill medication adherence measures compared with studies with self-report measures. CONCLUSIONS Overall, meta-analysis findings support the use of packaging interventions to effectively increase medication adherence. Limitations of the study include the exclusion of packaging interventions other than pill boxes and blister packs, evidence of publication bias, and primary study sparse reporting of health outcomes and potentially interesting moderating variables such as the number of prescribed medications.

Abstract
OBJECTIVE This meta-analysis systematically compiles intervention research designed to increase medication adherence among underrepresented adults. METHOD Comprehensive searching located published and unpublished studies with medication adherence behavior outcomes. Studies were included if samples were adults living in North America who had any of the following backgrounds or identities: African American, Native American, Latino, Latino American, Asian, Asian American, Pacific Islander, Native Alaskan, or Native Hawaiian. Random-effect analyses synthesized data to calculate effect sizes as a standardized mean difference and variability measures. Exploratory moderator analyses examined the association between specific efforts to increase the cultural relevance of medication adherence studies and behavior outcomes. RESULTS Data were synthesized across 5559 subjects in 55 eligible samples. Interventions significantly improved medication adherence behavior of treatment subjects compared to control subjects (standardized mean difference=0.211). Primary studies infrequently reported strategies to enhance cultural relevance. Exploratory moderator analyses found no evidence that associated cultural relevance strategies with better medication adherence outcomes. CONCLUSION The modest magnitude of improvements in medication adherence behavior documents the need for further research with clear testing of cultural relevance features.

Abstract
OBJECTIVES To meta-analyze lipid outcomes from supervised exercise interventions among healthy adults. METHODS Comprehensive search strategies identified trials testing supervised exercise interventions in samples of healthy adults. Data were coded and analyzed using random effects meta-analysis methods. Moderator analyses explored whether design, sample, or intervention characteristics were linked with lipid outcomes. RESULTS Data were analyzed from 344 comparisons. The overall mean effect size for 2-group comparisons was 0.28, corresponding to reduced total cholesterol of 8.65 mg/dl. Study effect sizes were greater where participants were obese at baseline, and for interventions utilizing low-intensity exercise. CONCLUSIONS Supervised exercise interventions can improve lipid outcomes for healthy adults, with possible greater improvement for obese individuals, and through low-intensity exercise.

Abstract
OBJECTIVE Although exercise can improve insulin sensitivity, no adequate synthesis exists of exercise intervention studies with regard to their effect on insulin sensitivity. This comprehensive meta-analysis synthesized the insulin sensitivity outcomes of supervised exercise interventions. METHOD Extensive literature searching located published and unpublished intervention studies that measured insulin sensitivity outcomes. Eligible studies tested supervised exercise interventions among healthy adults. Primary study characteristics and results were coded. Random-effects meta-analyses of standardized mean differences included moderator analyses. RESULTS Data were synthesized across 2509 subjects (115 samples, 78 reports). The overall mean effect size for 2-group postintervention comparisons was 0.38 (95% confidence interval [CI] = 0.25-0.51, I (2) = 0%) and for 2-group pre-post comparisons was 0.43 (95% CI = 0.30-0.56, I (2) = 52%; higher mean insulin sensitivity for treatment than control subjects). The postintervention mean of 0.38 is consistent with treatment subjects ending studies with a mean fasting insulin of 6.8 mU/L if control participants' mean fasting insulin were 7.9 mU/L. Exploratory moderator analyses did not document different insulin sensitivity effect sizes across intervention characteristics or sample attributes. CONCLUSION This study documented that exercise is a valuable primary care and community health strategy for healthy adults to improve insulin sensitivity and lower the risk for diabetes conferred by insulin resistance.

Abstract
Comparative effectiveness research seeks to identify the most effective interventions for particular patient populations. Meta-analysis is an especially valuable form of comparative effectiveness research because it emphasizes the magnitude of intervention effects rather than relying on tests of statistical significance among primary studies. Overall effects can be calculated for diverse clinical and patient-centered variables to determine the outcome patterns. Moderator analyses compare intervention characteristics among primary studies by determining whether effect sizes vary among studies with different intervention characteristics. Intervention effectiveness can be linked to patient characteristics to provide evidence for patient-centered care. Moderator analyses often answer questions never posed by primary studies because neither multiple intervention characteristics nor populations are compared in single primary studies. Thus, meta-analyses provide unique contributions to knowledge. Although meta-analysis is a powerful comparative effectiveness strategy, methodological challenges and limitations in primary research must be acknowledged to interpret findings.

Abstract
This meta-analysis is a systematic compilation of research focusing on various exercise interventions and their impact on the health and behavior outcomes of healthy African American, Hispanic, Native American, and Native Hawaiian adults. Comprehensive searching located published and unpublished studies. Random-effects analyses synthesized data to calculate effect sizes (ES) as a standardized mean difference (d) and variability measures. Data were synthesized across 21,151 subjects in 100 eligible samples. Supervised exercise significantly improved fitness (ES=.571-.584). Interventions designed to motivate minority adults to increase physical activity changed subsequent physical activity behavior (ES=.172-.312) and anthropometric outcomes (ES=.070-.124). Some ES should be interpreted in the context of limited statistical power and heterogeneity. Attempts to match intervention content and delivery with minority populations were inconsistently reported. Healthy minority adults experienced health improvements following supervised exercise. Interventions designed to motivate subjects to increase physical activity have limited magnitude heterogeneous effects.

Abstract
Older adults with hypertension are dependent on medication to control blood pressure and reduce risk for cardiovascular disease and renal impairment. Unfortunately, adherence to antihypertensive regimens remains low. This pilot study examines the relation among medication beliefs, demographic variables, and antihypertensive medication adherence in a sample of older adults (median age = 74 years). Medication beliefs were measured using the Beliefs About Medicines Questionnaire (BMQ), and medication adherence was measured by electronic monitoring. Among study participants (n = 33), concerns about medications were found to be related to poorer antihypertensive adherence. In particular, older adults with lower medication adherence were concerned about dependency and long-term effects from their medications. When controlling for other factors that may influence antihypertensive adherence, beliefs about medication necessity were related to adherence (odds ratio: 2.027, 95% confidence interval: 1.10-3.75).

Abstract
OBJECTIVE To explore the medication-taking behavior of successful kidney transplant recipients and determine what behaviors were common among this group. METHODS Open-ended interviews were conducted by telephone with 19 individuals who had successfully maintained a transplanted kidney for 25 years or more. Data were coded by using a grounded theory approach to explore patterns of phenomena, common descriptions, and relationships. RESULTS Four themes emerged as participants described the behaviors they developed to adhere successfully to the immunosuppressive medication required for maintaining their transplanted kidneys. The themes were reminder methods, obtaining medications, maintaining routines, and problem-solving strategies. Kidney transplant recipients identified the importance of developing and maintaining medication-taking skills and routines on medication adherence. Problem-solving abilities were also valuable during times of disruption of normal routines. CONCLUSIONS Interventions focusing on medication-taking skills, habit formation, and resources for problem solving may improve immunosuppressive medication adherence and clinical outcomes in kidney transplant recipients.

Abstract
This literature review explores the range and nature of medication adherence interventions tested with older adults. The unique needs of older adults require specifically designed and tailored interventions. Low medication adherence rates among some elderly contribute to inadequate pharmacological management of illnesses. Searches were conducted to identify randomized controlled trials of medication adherence; computerized databases, journal hand searches, and ancestry searches yielded 63 studies published between 1977 and 2005 where participants' mean age was > 60 years. Interventions were categorized by focus (patient, medication, and administration factors). Most were geared toward promoting knowledge and skills for medication-taking and adherence. Gaps were noted in addressing memory aids and self-monitoring strategies; further development of interventions addressing medication and administration factors influencing adherence are also needed. Identified interventions are geared toward self-medicating patients and fail to address caregivers administering medications. Finally, interventions do little to address variations in patterns of adherence among older adults.

Abstract
Prior exercise experiences may influence interpretations of exercise, ultimately affecting exercise behavior. This study examines differences in interpretations of exercise in older adults based on prior exercise behavior. Older adults who report more exercise behavior were hypothesized to score more positively on measures of interpretations of exercise than older adults reporting less exercise behavior. Two hundred fifteen older adults reported prior-year exercise behavior, and within a 2-week exercise training program reported their episode-specific and general interpretations of exercise. High exercisers reported higher perceptions of energy (p = .021), life enhancement (p = .023), and overall psychological outlook (p = .003) than low exercisers. Several gender differences were also noted. These results support earlier findings that older adults' beliefs and interpretations of exercise activity influence exercise behavior.
