Type 2 diabetes mellitus is a risk factor for developing dementia and a public health concern around the world. Identifying any predictive factors associated with diabetes‐related dementia prevention behaviors are of value in helping to prevent dementia. From six community hospitals in Chiang Mai, Thailand, 182 people aged 30–60 years were enrolled in a cross‐sectional study and completed a written questionnaire on dementia prevention behaviors and perceptions of health beliefs. Multiple linear regression analysis was applied to determine possible associations between dementia prevention behaviors and health belief perceptions. A high level of preventive behavior was associated with high perceptions of the benefits of, and barriers to, dementia prevention and longer duration of patients' diabetes. Findings indicate the predictive role of the two factors in the perception of health beliefs about dementia prevention behaviors among the participants. Although further testing with different samples and in different locations is warranted, education programs for health practitioners that integrate the findings of this study would be beneficial to improvement of dementia prevention behaviors in people with diabetes.

Healthy lifestyle levels are low among adults with hypertension (HTN). Unfortunately, psychosocial factors contributing to patients’ inability to meet healthy lifestyle recommendations are not well-understood. This integrative review examined the relationships of three psychosocial factors (self-efficacy, outcome expectancy, and social support) with dietary adherence (DA) and physical activity (PA) among adults with HTN. In total, 24 peer-reviewed studies were assessed. Results showed self-efficacy had small-to-large relationships with PA ( r = 0.02–0.46) and DA ( r = 0.06–0.79), with the strength of the associations varying by the assessed domain and country of origin. However, few studies reported a small relationship between the remaining factors (outcome expectancy and social support) and PA and DA. Thus, more efforts are needed to delineate the contributions of social support and outcome expectancies on DA or PA. When designing an intervention that focuses on improving PA or DA among adults with HTN, these psychosocial factors should be targeted.

Effective strategies to promote a long-term healthy lifestyle among hypertensive patients remain unclear. Social cognitive theory (SCT)-based interventions have demonstrated some effectiveness in promoting sustainable lifestyle change in this population. This systematic review aims to synthesize randomized controlled trials (RCTs) examining the effect of SCT-based interventions on healthy lifestyles, including physical activity [PA] and/or diet adherence [DA], in hypertensive patients. Four electronic databases (CINAHL, PubMed, Scopus, and Web of Science) were searched to identify RCTs that: 1) targeted hypertensive patients; 2) reported PA and/or DA as proximal outcomes; and 3) included an intervention guided by the SCT. Narrative and tabulation synthesis were conducted to present the effects of the SCT-based interventions. Fifteen studies were included in this systematic review with 3,388 hypertensive patients (mean age = 52.21, 68.70% female). Findings were inconsistent for the SCT-based interventions targeting multiple behaviors, including DA and PA. Multiple-component interventions, including PA training and identification of PA barriers through group discussion, had a greater effect size on PA improvement (d = .93–.99) than interventions without these components (d = .29–.44). Interventions with a longer duration (> 12 weeks), greater length of time for sessions (150 minutes/session), and higher session frequency (2 days/week) were more effective on DA change (d = .65) than interventions with a shorter duration (< 12 weeks), shorter session length (60–90 minutes), or lesser session frequency (monthly meeting) (d = .09–.51).
