“…21 Patients received tailored counseling for each target behavior based on their current stage of change. SMI used the processes of change using the cognitive and behavioral activities found to be most effective for each stage, 22,23 and incorporated decisional balance and self-efficacy. For the decisional balance, the pros and cons of each behavior were elicited, and the counselor explored why each pro endorsed was important to the participant.…”

Effectiveness of a Tailored Behavioral Intervention to Improve Hypertension Control

M ore than 65 million American adults have hypertension.1 Diet, exercise, and drugs are mainstays of hypertension management. 2 The efficacy of hypertension treatment in preventing cardiovascular events is established.2 Although the system and provider interventions have improved blood pressure (BP) control rates from the previous low rate (27% 3 ) to more respectable rates (51% 1 to 79% 4,5 ), the substantial proportion remains uncontrolled. However, we may have reached the maximum control achievable with nontailored interventions targeting clinics or hospitals with growing concerns that such interventions may lead to overtreatment and adverse outcomes. 4,6 To optimize hypertension control further, approaches to identify and target patients at risk, to whom appropriately tailored therapy can then be offered, are needed.Suboptimal adherence is a common, but modifiable, problem leading to inadequate hypertension control. Fewer than 10% of adults with hypertension adhere fully to diet recommendations, 7 ≈35% exercise regularly, 8 and only 50% to 60% are fully medication adherent.9 In-person counseling to improve adherence requires time and is labor-intensive and costly. Telephone counseling offers a promising alternate approach, 10 and such counseling can be delivered at a convenient time and setting. 11Telephone interventions have improved medication adherence, 12,13 physical activity, 14 and diet, 15 all key to lowering BP. It is not known, however, whether novel theory-based behavioral interventions can be delivered by telephone and whether they are effective in busy, clinical settings.We conducted a randomized controlled trial to evaluate the effectiveness of targeting patients with repeated uncontrolled hypertension with either a tailored or a nontailored intervention in improving hypertension control and systolic blood pressure (SBP). Methods Design, Setting, and ParticipantsThe study was a randomized controlled trial to evaluate whether a telephone-delivered, behavioral stage-matched intervention (SMI) or a nontailored health education intervention (HEI) would lead to better BP control than usual care (UC) in patients with uncontrolled BP.The study was approved by the institutional review board. All participants provided written informed consent. Procedures were See Editorial Commentary, pp 273-275Abstract-Blood pressure (BP) control rates are suboptimal. We evaluated the effectiveness of 2 behavioral interventions to improve BP control via a 3-arm, randomized controlled trial of 533 adults with repeated uncontrolled BP, despite antihypertensive drug treatment for ≥6 months. The interventions were a tailored stage-matched intervention (SMI) or a nontailored health education intervention (HEI) of 6 monthly calls targeting diet, exercise, and medication. Control was usual care (UC). There were no baseline group differences.

“…It appears that other variables, not measured in this study, may have caused the changes in physical activity. For example, behavioral processes of change (transtheoretical model), which have been shown to mediate change in physical activity in other studies, [15,21,33] were not assessed in this study. Although social support, self-efficacy and self-regulation were not found to be significant mediators in this study, the importance of these variables in changing older adults' physical activity should not be discounted.…”

“…Many theoretical constructs have been tested as mediators of change and results are not consistent. Self-efficacy, [10,16,20] Social support, [10] goal setting, [16,19] and behavioral processes [15,21] have been found to mediate change in physical activity behavior in some studies, although other studies have not found support for some of these constructs [12,13,16,19]. It is important to note that the samples included in these studies are quite diverse (i.e., older adults, pregnant women, cancer survivors, healthy populations).…”

Objective: Although progress has been made in developing effective interventions that change physical activity behaviors, much work remains in understanding how interventions exert their effects. The purpose of this study was to examine psychosocial mediators of change in physical activity resulting from a group-based, behavioral, physical activity intervention (Active Living Every Day) in older adults. Methods:This study was a randomized controlled trial carried out in 2015. Participants (n=47) completed a survey assessing demographic and psychosocial variables, and wore an Actigraph at baseline and 12 weeks (postintervention). A multiple mediator model, testing social support (family and friends separately), self-efficacy, and self-regulation as mediators of change in physical activity was conducted. Results:Results showed that the intervention was not successful in changing the targeted mediators, and changes in mediators were not associated with changes in physical activity. None of the variables examined were significant mediators of change in physical activity. Conclusion:Despite significant changes in physical activity, the mechanisms by which the changes occurred are unknown. Potential explanations and implications of the null findings are discussed. Continued efforts focused on understanding how behavioral interventions exert their effects on physical activity outcomes are needed in an effort to develop the most efficacious and costeffective interventions aimed at improving health.

ResumoDiabetes Mellitus (DM) tipo 2 (DM2) é um problema de saúde pública que requer cuidados contínuos e multidisciplinares. A presente revisão tem por objetivo destacar a importância da inclusão de atividades físicas em programas de atenção em DM2, salientando seu efeito no controle glicêmico e aspectos que influenciam a adesão de usuários, bem como associar a temá-tica às atuais políticas públicas de atenção básica em saúde no Brasil. Artigos originais, revisões sistemáticas e de meta-análise que continham os termos DM2, adesão, exercício físico, atividade física e programa de educação em DM (em português e inglês) encontrados nos bancos de dados PubMed, Scopus e BioMed Central foram incluídos. Políticas públicas e diretrizes (guidelines) também foram utilizadas para contextualização e discussão. Evidências indicam que a participação em programas de atenção à DM2 se associa a um melhor prognóstico da doença; indivíduos mais aderentes apresentam melhores resultados no controle glicêmico e redução da massa corporal que os menos aderentes. Fatores como supervisão profissional, envolvimento em grupos, apoio familiar, tipo de exercício e frequência de encontros podem influenciar diretamente a adesão a esses programas. Educação em DM, atividades físicas e terapia nutricional são importantes no tratamento da DM2, porém, há escassez de programas públicos de saúde que, de forma multidisciplinar e contínua, contemplem estas ações terapêuticas. Palavras-chaveDiabetes mellitus tipo 2; Atenção primária em saúde; Terapia e educação; Exercício; Glicemia.
