Models and theories of health behavior and clinical interventions in aging: a contemporary, integrative approach

The meaning of health to persons aging with longstanding multiple sclerosis

Understanding how persons aging with a chronic condition view their health is essential for planning and delivering person-centered care. The purpose of this study was to explore how persons aging with the chronic and disabling condition multiple sclerosis (MS) describe their health and how this has changed over time using data from Years 1 to 26 of an ongoing longitudinal survey study of health promotion and quality of life for persons with MS. The survey included measures of perceived meaning of health, self-rated health, health behaviors and quality of life outcomes. The sample included 168 persons with MS who returned the survey at Time 1 (1996) and again at Time 26 (2022). In 2022, participants had a mean age of 70.13 (SD = 8.19) and had been diagnosed with MS for an average of 34.47 years (SD = 6.27). Sixty percent of participants rated their overall health as good or excellent. Decreases in health self-ratings over time were not significant. Participants consistently agreed more strongly with items reflecting a wellness-oriented view of health than those reflecting a more clinical/biomedical model. At both time points, clinical definitions of health were negatively related and wellness definitions were positively related to reported frequency of health behaviors. Findings suggest that persons aging with the chronic condition of MS may be more responsive to health messages that emphasize function in daily living, carrying out normal responsibilities, and adjusting to changes in environment and demands. Patient or Public Contribution: Persons with MS provided study data, input on design, and construct measurement.

Medical weight loss in older persons with obesity

The prevalence of individuals with obesity or overweight has steadily increased over the past decades both worldwide, and in the United States. This trend is also evident in the older adult population, which has experienced a continuous rise in the number of individuals with overweight or obesity. This is relevant due to the impact of obesity in older adults' quality of life, physical function, morbidity, and healthcare costs. This review aims to provide practical guidance and currently available approaches for healthcare professionals in managing this population. Both non-pharmacological methods such as intensive behavioural therapy, nutritional interventions, and physical activity, as well as anti-obesity medications, are discussed, with a focus on their potential positive and negative effects in older adults. Additionally, bariatric therapy is evaluated, including current procedures available and the associated results and risks in the older population.

Does government food demonstration intervention influence household dietary diversity in the Upper West Region of Ghana?

Dietary diversity is crucial in ensuring food and nutrition security. In low-middle-income countries, people frequently prioritize the quantity of food they consume over its quality due to a lack of availability and financial limitations. As a result, achieving dietary diversity is often overlooked in favor of ensuring adequate caloric intake. Through a social cognitive theory perspective, our study examines the relationship between food demonstrations and household dietary diversity in Ghana's Upper West Region utilizing cross-sectional survey data from 517 smallholder farmer households. The results from ordered logistic regression presented in odds ratio (OR) show that participating in food demonstrations (OR: 2.585, p<0.01), engaging in home gardening (OR: 1.932, p<0.001), having access to credit (OR: 1.609, p<0.01), self-rated good nutritional status (OR: 1.747, p<0.01), and Waala ethnicity (OR: 3.686, p<0.001) were all positively associated with high household dietary diversity. Conversely, living in the Wa West district was associated with lower dietary diversity (OR: 0.326, p<0.001). Our research findings suggest that policymakers may want to consider implementing community-based educational programs, such as home and school visits for food demonstrations and sensitizations, promoting mother-to-mother support groups for dietary diversity education, nutrition counseling services, and using role-play and local media. In addition, strengthening local agricultural policies through food banks, indigenous seed development, and mobile food markets and enhancing public-private partnerships like the Ghana Schools Feeding Programme and National Food Buffer Stock company could improve the supply chain and distribution networks for diverse food items. Implementing these interventions in the Upper West Region of Ghana could improve health, well-being, food security, and nutritional outcomes.

Addressing Disparities in Acute Stroke Management and Prognosis

There are now abundant data demonstrating disparities in acute stroke management and prognosis; however, interventions to reduce these disparities remain limited. This special report aims to provide a critical review of the current landscape of disparities in acute stroke care and highlight opportunities to use implementation science to reduce disparities throughout the early care continuum. In the prehospital setting, stroke symptom recognition campaigns that have been successful in reducing prehospital delays used a multilevel approach to education, including mass media, culturally tailored community education, and professional education. The mobile stroke unit is an organizational intervention that has the potential to provide more equitable access to timely thrombolysis and thrombectomy treatments. In the hospital setting, interventions to address implicit biases among health care providers in acute stroke care decision-making are urgently needed as part of a multifaceted approach to advance stroke equity. Implementing stroke systems of care interventions, such as evidence-based stroke care protocols at designated stroke centers, can have a broader public health impact and may help reduce geographic, racial, and ethnic disparities in stroke care, although further research is needed. The long-term impact of disparities in acute stroke care cannot be underestimated. The consistent trend of longer time to treatment for Black and Hispanic people experiencing stroke has direct implications on long-term disability and independence after stroke. A learning health system model may help expedite the translation of evidence-based interventions into clinical practice to reduce disparities in stroke care.

The Use of the Health Belief Model in the Context of Heatwaves Research: A Rapid Review

As heatwaves increase and intensify worldwide, so has the research aimed at outlining strategies to protect individuals from their impact. Interventions that promote adaptive measures to heatwaves are encouraged, but evidence on how to develop such interventions is still scarce. Although the Health Belief Model is one of the leading frameworks guiding behavioral change interventions, the evidence of its use in heatwave research is limited. This rapid review aims to identify and describe the main themes and key findings in the literature regarding the use of the Health Belief Model in heatwaves research. It also highlights important research gaps and future research priorities. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 10 articles were included, with a geographic distribution as follows: United States (n = 1), Australia (n = 1), Pakistan (n = 1), and China (n = 1), as well as Malaysia (n = 2), Germany (n = 1), and Austria (n = 1). Results showed a lack of research using the Health Belief Model to study heatwaves induced by climate change. Half of the studies assessed heatwave risk perception, with the 2 most frequently used constructs being Perceived Susceptibility and Perceived Severity. The Self-efficacy construct was instead used less often. Most of the research was conducted in urban communities. This review underscores the need for further research using the Health Belief Model.

Pressurizing or encouraging: Health behaviors among long-distance couples

Couples in long-distance relationships face unique challenges that affect their health outcomes and relationship dynamics in ways that are different from couples in close proximal relationships (PR). The results of previous literature analyzing health outcomes for long-distance relationship (LDR) couples have been mixed, and factors such as couple satisfaction and gender of the individuals contribute to the variance. This study examined the good health practices of couples in LDRs, the ways in which partners influence each other's health, and the health outcomes of these couples as compared to couples in PRs. Multilevel multivariate analysis showed that couples in LDRs had better health practices than those in PRs, and men overall had poorer health practices than women. There was no main effect seen for LDRs when we examined strategies used for influencing health. There was a main effect for gender, though, and we found that women tend to use more collaborative and pressurizing strategies for influencing their partner's health. On health indices, we found that LDR couples tended to have lower levels of fatigue and sleep disturbance as compared to PR couples. In the adjusted model with covariates, which included age, income, couple satisfaction, and married or unmarried couples, we found that lower couple satisfaction and lower income significantly predicted poorer health on all health indices. These results are discussed in light of unequal gender roles, social control, and positive aspects of LDRs on health in an attempt to understand LDRs better and destigmatize the narrative of these relationships as 'less than' PRs. Implications for health and mental health practitioners are also discussed.

Understanding the diabetes self-care behaviour in rural areas: Perspective of patients with type 2 diabetes mellitus and healthcare professionals

BACKGROUND

Diabetes self-care behaviour plays a crucial role in managing the diabetes effectively and preventing complications. Patients with type 2 diabetes mellitus (T2DM) and health care professionals (HCPs) of rural areas often face unique challenges when it comes to diabetes self-care practices (SCPs). Therefore, this study aim to explore the perspectives of patients with T2DM and HCPs on diabetes SCPs.

METHODS

Eight focus group discussions (FGDs) among individuals with T2DM and In-depth interviews (IDIs) with 15 HCPs were conducted in rural areas of Punjab, North India. Capability, Opportunity, Motivation, and Behaviour model (COM-B) was employed for thematic framework analyses.

RESULTS

The study participants perceived that a limited understanding of diabetes mellitus (DM), beliefs in alternative therapies, drug side effects, attitudes towards DM (psychological capability), comorbidities (physical capability), family support (social opportunity), financial and time constraints, and weather conditions (physical opportunity) contributed to lack of DM SCPs. Physicians' guidance and support were motivating them to adhere to SCPs, especially when aligned with their sense of self-efficacy (reflective motivation). HCPs constraints in providing patient-centred care are due to training limitations (psychological capability) and a lack of essential resources (physical opportunities). Participants expressed need for comprehensive diabetes care (automatic motivation) through structured diabetes education intervention to improve diabetes SCPs.

CONCLUSIONS

The study findings indicate that various factors influence diabetes SCPs from the perspectives of both patients with T2DM and HCPs and emphasizes the need for a multi-faceted approach to improve diabetes SCPs in rural areas. Implementing a structured diabetes self-care intervention strategy in rural areas may help for preventing and mitigating the impact of diabetes-related complications in rural areas.

Timing theory integrated nursing combined behavior change integrated theory of nursing on primiparous influence

BACKGROUND

The comprehension and utilization of timing theory and behavior change can offer a more extensive and individualized provision of support and treatment alternatives for primipara. This has the potential to enhance the psychological well-being and overall quality of life for primipara, while also furnishing healthcare providers with efficacious interventions to tackle the psychological and physiological obstacles encountered during the stages of pregnancy and postpartum.

AIM

To explore the effect of timing theory combined with behavior change on self-efficacy, negative emotions and quality of life in patients with primipara.

METHODS

A total of 80 primipara cases were selected and admitted to our hospital between August 2020 and May 2022. These cases were divided into two groups, namely the observation group and the control group, with 40 cases in each group. The nursing interventions differed between the two groups, with the control group receiving routine nursing and the observation group receiving integrated nursing based on the timing theory and behavior change. The study aimed to compare the pre- and post-nursing scores of Chinese Perceived Stress Scale (CPSS), Edinburgh Postpartum Depression Scale (EPDS), Self-rating Anxiety Scale (SAS), breast milk knowledge, self-efficacy, and SF-36 quality of life in both groups.

RESULTS

After nursing, the CPSS, EPDS, and SAS scores of the two groups was significantly lower than that before nursing, and the CPSS, EPDS, and SAS scores of the observation group was significantly lower than that of the control group (P = 0.002, P = 0.011, and P = 0.001 respectively). After nursing, the breastfeeding knowledge mastery, self-efficacy, and SF-36 quality of life scores was significantly higher than that before nursing, and the breastfeeding knowledge mastery (P = 0.013), self-efficacy (P = 0.008), and SF-36 quality of life (P = 0.011) scores of the observation group was significantly higher than that of the control group.

CONCLUSION

The integration of timing theory and behavior change integrated theory has been found to be an effective approach in alleviating negative mood and stress experienced by primipara individuals, while also enhancing their self-efficacy and overall quality of life. This study focuses on the key concepts of timing theory, behavior change, primipara individuals, negative mood, and quality of life.

Genus Curcuma: chemical and ethnopharmacological role in aging process

Aging or senescence is part of human life development with many effects on the physical, mental, and physiological aspects which may lead to age-related deterioration in many organs. Genus Curcuma family Zingieraceae represents one of the well-studied and medically important genera with more than eighty species. The genus is reported to contain different classes of biologically active compounds that are mainly presented in diphenylheptanoids, diphenylpentanoids, diphenylalkanoids, phenylpropene derivatives, alkaloids, flavonoids, chromones, terpenoids, phenolic acids and volatile constituents. Rhizomes and roots of such species are rich with main phytoconstituents viz. curcumin, demethoxycurcumin and bis-demethoxycurcumin. A wide variety of biological activities were demonstrated for different extracts and essential oils of genus Curcuma members including antioxidant, anti-inflammatory, cytotoxic and neuroprotective. Thus, making them as an excellent safe source for nutraceutical products and as a continuous promising area of research on lead compounds that may help in the slowing down of the aging process especially the neurologic and mental deterioration that are usually experienced upon aging. In this review different species of the genus Curcuma were summarized with their phytochemical and biological activities highlighting their role as antiaging agents. The data were collected from different search engines viz. Pubmed®, Google Scholar®, Scopus® and Web of Science® limiting the search to the period between 2003 up till now.

The theory behind and factors influencing the use of telemedicine during the COVID-19 pandemic: A systematic review

A paradigm change in patient health care toward telemedicine services was necessary in 2020 due to the COVID-19 pandemic, which broke out at the end of 2019. Theories used in determining the determinants of telemedicine utilization are various theories. Research conducted on the use of telemedicine still has doubts about the basic theory used in analyzing the factors that influence telemedicine, especially during the Covid-19 pandemic. The goal of this study is to outline the fundamental principles of telemedicine utilization during the Covid-19 outbreak and the variables that affect it. This Literature Review uses the scoping review method with the tool procedure, namely PRISMA. Based on the conducted literature review, there are 12 scholarly papers addressing the variables that affect the utilization of telemedicine services. During the Covid 19 epidemic, more individuals in many nations used telemedicine services. Anderson's theory of health care use and the idea of technology adoption or acceptance serve as the foundational theories for forecasting the variables that affect the use of telemedicine. The utilization of telemedicine is influenced by 29 different factors that come from different theories. The desire for health, exposure to COVID 19, co-morbidities, social media usage, avoiding contamination, time efficiency, ease of use of services, social impact, and hedonic incentive are among the factors associated to the COVID 19 pandemic.

Understanding COVID-19 Vaccine Uptake and Hesitancy among People with HIV in Freetown, Sierra Leone: A Cross-Sectional Study

People with HIV (PWH) incur a higher risk of COVID-19-related morbidity and mortality rates, yet less is known about COVID-19 vaccine uptake and hesitancy in this group. We conducted a cross-sectional study in Freetown, Sierra Leone, from April to June 2022, using the VAX scale, a validated instrument, to assess attitudes towards COVID-19 vaccination and calculate the hesitancy (VAX) scores. We used generalized linear models to identify the factors associated with vaccine hesitancy. Overall, 490 PWH were enrolled (71.4% female, median age: 38 years, median CD4 count: 412 cells/mm3). About 17.3% received ≥1 dose of a COVID-19 vaccine. The mean VAX score was 43.14 ± 7.05, corresponding to 59.9% participants being vaccine-hesitant. A preference for natural immunity (65.8%) and concerns about profiteering (64.4%) were the commonest reasons for hesitancy, followed by a mistrust of vaccine benefits (61.4%) and worries about future effects (48.0%). In the adjusted regression analysis, being a Muslim (β = 2.563, p < 0.001) and having an urban residence (β = 1.709, p = 0.010) were associated with greater vaccine hesitancy, while testing for COVID-19 was associated with reduced vaccine hesitancy (β = -3.417, p = 0.027). These findings underscore the importance of addressing vaccine hesitancy as a critical element boosting COVID-19 vaccine uptake among PWH.

Factors Associated with COVID-19 Vaccine Hesitancy and Case Status among New Jersey Secondary Educational Professionals

BACKGROUND

Vaccine hesitancy remains a societal problem, including during the COVID-19 pandemic. New Jersey (NJ) Safe Schools Program provides work-based learning training to supervisory-level career-technical-vocational education teachers and administrators who have to consider varied state and local mandates concerning COVID-19 vaccination and exemptions.

METHODS

In early 2022, we distributed an online survey via PsychData to individuals trained between 2014 and 2022 to understand NJ teachers' practices and concerns regarding COVID-19 vaccines. Overall, 269 completed the survey. We stratified data by vaccination status, number of doses, booster status, age, teaching experience, gender, race, county of work, and COVID-19 diagnosis status.

RESULTS

Overall, results suggested differences in COVID-19-related concerns, including access to, perceptions of, and confidence in COVID-19 vaccines and COVID-19-related practices. About 90.7% received the initial vaccine; 77.7% received the booster. About half the participants had received a positive COVID-19 diagnosis by the time of the survey; they were less likely to get the vaccine or booster if they had received the initial vaccine.

CONCLUSIONS

Data suggested differences in levels of COVID-19-related concerns and confidence in, or importance of, vaccines when comparing different demographic factors and vaccination practices. The data informs efforts to understand factors affecting vaccine hesitancy among educational professionals.

Differences in the association of oral health knowledge, attitudes, and practices with frailty among community-dwelling older people in China

BACKGROUND

Oral health and frailty are significantly related and should be well examined, especially in late life. Few studies have explored the relationship of oral health knowledge, attitudes, and practices with frailty and examined sociodemographic variations in this association. This study aimed to examine the association between oral health knowledge, attitudes, practices and frailty, with a special focus on comparing differences in their association among the Chinese community-dwelling older population.

METHODS

This study included 4218 community-dwelling older adults (aged ≥ 60 years) who participated in a cross-sectional survey. Sociodemographic characteristics, oral health knowledge, attitudes, practices, and frail status (non-frailty, pre-frailty, and frailty) were collected with a face-to-face questionnaire-based interview. Multivariate logistic regression models were used to evaluate the association of oral health knowledge, attitudes, and practices with frailty.

RESULTS

Of the 4218 participants, 36.2% (n = 1527) and 18.8% (n = 792) were classified as pre-frailty and frailty. Age, gender and educational attainments differences existed in the association of oral health knowledge with frailty. Urban-rural differences in the association of oral health knowledge and practices with frailty were also found. Specifically, oral health knowledge was significantly related to frailty only among participants aged 70-79 years (adjusted odds ratio [95% confidence interval]) (1.08 [1.02-1.15]), females (1.05 [1.00-1.10]), rural residents (1.06 [1.01-1.12]), and those who were primary school and lower education (1.06 [1.01-1.11]), whereas oral health practices were related to frailty only among urban participants (0.96 [0.92-1.00]).

CONCLUSION

This study confirmed the different associations of oral health knowledge and practices with frailty among community-dwelling older people in China. Further research is needed to better understand the abovementioned differences and public health strategies are required to improve oral health literacy and thereby contain the development of frailty in later life.

Telehealth Use Among Older Adults With Sensory, Cognitive, and Physical Impairments: A Substitute or Supplement to Traditional Care?

OBJECTIVES

Telehealth use flourished during the COVID-19 pandemic, as older patients faced obstacles to seeking in-person care. Heavy reliance on telehealth may continue postpandemic, due to increased Medicare investments in its use. However, it is unclear if older adults with disabilities face obstacles to effective telehealth use. We evaluate (a) how sensory, physical, and cognitive impairments affect older adults' use of telehealth only, traditional in-person care only, neither, or both (i.e., combined care); and (b) whether these patterns differ on the basis of socioeconomic and social resources that may facilitate telehealth use.

METHOD

Data are from the Self-Administered Questionnaire in the 2020 wave of the Health and Retirement Study (n = 4,453). We estimated multinomial logistic regression models to evaluate associations between impairments and health care service use and tested 2-way interaction terms to evaluate moderation effects.

RESULTS

Persons without impairments were most likely to use combined care, considered the optimal form of care. Persons with vision or cognitive impairment were more likely to use telehealth or traditional care only, whereas persons with 3 or more physical limitations were least likely to use telehealth alone, relative to combined care. Patterns did not differ significantly on the basis of any of the potential moderators.

DISCUSSION

We discuss implications for health care policy and practice, in light of reimbursement changes proposed by the Centers for Medicare and Medicaid Services for telehealth services. These proposals include the elimination of voice-only services which may be particularly beneficial to vision-impaired older adults.

Understanding COVID-19 Vaccine Uptake and Hesitancy Among People With HIV in Freetown, Sierra Leone: A Cross-sectional Study

Objectives

People living with HIV (PWH) are at increased risk of COVID-19 related morbidity and mortality, yet less is known about COVID-19 vaccination uptake and hesitancy, especially in sub-Saharan Africa. We aimed to evaluate COVID-19 vaccine uptake and hesitancy among PWH in Sierra Leone.

Methods

We conducted a cross-sectional study in a convenience sample of PWH in routine care at Connaught Hospital in Freetown, Sierra Leone from April through June 2022. We collected sociodemographic and health-related data. We used the VAX Scale, a validated instrument to assess attitudes towards COVID-19 vaccination. From the responses, we constructed hesitancy (VAX) scores, with higher scores implying negative attitudes towards vaccination. We used generalized linear models to identify factors associated with vaccine hesitancy.

Results

A total of 490 PWH were enrolled (71.4% female, median age 38 years, median CD4 count 412 cells/mm3, 83.9% virologically suppressed). About 17.3% had received at least one dose of a COVID-19 vaccine. The mean VAX score was 43.14 ± 7.05, corresponding to 59.9% participants classified as vaccine hesitant. Preference for natural immunity (65.8%) and concerns about commercial profiteering (64.4%) were the commonest reasons for hesitancy, followed by mistrust of vaccine benefits (61.4%) and worries about future side effects (48.0%). In adjusted regression analysis, being Muslim (β = 2.563, p < 0.001) and residence in urban areas (β = 1.709, p = 0.010) were associated with greater vaccine hesitancy, while having tested ever for COVID-19 was associated with lesser vaccine hesitancy (β = -3.417, p = 0.027).

Conclusion

We observed a low COVID-19 vaccine uptake and high hesitancy among PWH in Sierra Leone. Our findings underscore the need to address vaccine hesitancy as a critical element of efforts to boost COVID-19 vaccine uptake among this population in Sierra Leone.

Subjective expectation of reaching age 85: agreement with population statistics and association with behavioral and psychological factors

BACKGROUND

It is not clearly known how well Danes estimate their chances of reaching the average life expectancy and whether identifiable population subgroups misestimate their life expectancy, and potentially also investments and savings in health and pensions. Therefore, in this study, we examined on the individual level whether subjective life expectancy is in line with the statistically calculated chance of reaching age 85, and further explored the psychological and behavioral factors associated with under or overestimation.

METHODS

We opted for a cross-sectional survey design based on a sample of 5,379 Danish citizens aged 50-70 years, returning a web-based questionnaire with socio-demographic data supplemented from a national registry. Average participant estimates of their chance of reaching age 85 for each age range and sex group were compared with actuarial data. We then performed multiple linear regression analyses to examine factors associated with the subjective expectancy of reaching age 85 years.

RESULTS

We found that 32% of females and 23% of males reported 100% certainty of reaching age 85, and average expected survival chance exceeded the statistically predicted survival chance for 23% of males and 16% for females in age-ranges 50-60 and 61-70. Our multivariable analysis found that health literacy, internal health locus of control, willingness to take health risks, self-rated health, and health and life satisfaction all showed a significant positive association with expectation of reaching age 85. Moreover, those on daily medications, ex- or current smokers, and heavy drinkers were significantly less optimistic about reaching age 85.

CONCLUSIONS

Particularly for the population groups with inaccurate life expectancies, the significant associations with psychological and behavioral factors open a way for initiatives based on behavior change theories to reach a better agreement between subjective and statistical life expectancy.

Logic model for opioid safety in chronic non-malignant pain management, an in-depth qualitative study

BACKGROUND

Opioids are commonly used for the management of chronic non-malignant pain in Pakistan; but there is a lack of literature around precursors or motivators in the use of opioids.

AIM

The study holistically explored factors contributing towards the unsafe use of opioids and identifies strategies to overcome them.

METHOD

Exploratory qualitative methods using interviews, focus groups and non-participant observational case studies were used. Interviews and focus groups were carried out face-to-face as well as virtually and observations were conducted in community pharmacies in Islamabad and Khyber Pukhtoon Khuwa province, Pakistan. Data were collected from 4 stakeholder groups; pharmacy policy makers (n = 11), people with chronic non-malignant pain (n = 14), doctors (n = 31) and community pharmacists (n = 36) by purposive critical case sampling method. Data were analysed inductively using reflexive thematic analysis and then deductively mapped to a social ecological framework. Non-participant observations were analysed using a cross case synthesis using explanation building technique. Data from all three methods were triangulated to develop a logic model.

RESULTS

Identified factors at macro (regulation), meso (social perceptions of pain and opioids) and micro levels (uncontrolled pain, self-medication, health literacy) and strategies are presented holistically and were used to develop a logic model for the prevention and mitigation of factors currently causing unsafe use of opioids.

CONCLUSION

The study provides an in-depth view of factors contributing towards diversion of pharmaceutical opioids and can help guide national and international policy makers in their future initiatives to promote safe use of opioids in the management of chronic non-malignant pain in Pakistan.

Older patients' perspectives on participating in multimodal rehabilitation including anabolic steroids following hip fracture: a qualitative study embedded within a pilot RCT

PURPOSE

To explore patient perspectives of participating in a pilot RCT evaluating feasibility and effect of anabolic steroid, physiotherapy and nutritional supplement following hip fracture.

METHODS

Semi-structured telephone-based interviews of 16 women and three men (average age 73 years) were conducted at baseline and after a 12-week intervention. Qualitative content analysis was performed.

RESULTS

Two main categories were identified: (1) Trust and hope for a positive change with three sub-categories; reflections on anabolic steroids, anticipation of extra attention, lack of energy. (2) Curiosity, care, and commitment with four sub-categories; a sense of anabolic steroids, feeling of exclusivity and privileges, challenges and sense of obligation, and perspectives on personal gain.

CONCLUSIONS

Findings suggest high acceptability of the intervention. Participants motivated their participation on a trust that the intervention would "do more good than harm". They found the randomization and possibility of receiving anabolic steroids intriguing, and especially valued trial participation because of their experience of getting extra care and "deluxe" rehabilitation including close contact and support by health professionals. Our findings may help inform future research recruiting older patients and generally considered relevant for health professionals in rehabilitation, emphasizing the impact of professional guidance and social support to encourage self-efficacy.Implications for rehabilitationWith muscle enhancing medicine being suggested as a supplement in rehabilitation following hip fracture, exploring patients' perspectives is warranted and may help inform future trials in this area.Factors reported as important by older adults for engaging in rehabilitation trials are: simple but thorough information, friendly and trustful relation with study staff and opportunities of extra care and attention.Older patients with hip fracture highly valued professional guidance and support by health professionals during the rehabilitation intervention. High acceptability was identified for the supervised outpatient rehabilitation, where especially the individually structured progressive strength training was highlighted as the "active ingredient" accelerating recovery and potentially promoted self-efficacy.

Self-reported visual impairment and depression of middle-aged and older adults: The chain-mediating effects of internet use and social participation

Background

Visual impairment (VI) is a strong predictor of depression in middle-aged and older adults. However, the underlying mechanisms and pathways have not been well characterized. The purpose of this study was to determine whether Internet use and social participation mediate the effects of self-reported VI on depression.

Methods

The study used the fourth wave of cross-sectional data from the China Health and Retirement Longitudinal Study, including 19,766 Chinese adults. Depression was assessed according to the CES-D 10 International Scale. Logistic regression models were used to examine the relationship between self-reported VI and depression. While adjusting for relevant covariates, the PROCESS macro (model nos. 6 and 91) was used to assess the chain-mediating effects of Internet use and social participation.

Results

A total of 17,433 respondents were included in this study. The CES-D 10 results showed that 7,327 middle-aged and older adults had depressive symptoms, of whom 39.5% were male and 10.2% were ≥75 years old. 32.1% of respondents self-reported VI. Regression analysis showed a positive association between VI and depression, while Internet use and social participation had a negative predictive effect on depression. In the mediation analysis, the social participation pathway contributed the most to the total effect, accounting for 52.69% of it. The proportion of Internet use is 37.72%. When these two mediators were considered together in the full model, they accounted for 9.58% of the total effect of VI on depression.

Conclusion

Internet use and social participation were important mediators that mitigated the effects of VI on depression. Combined with previous evidence, online activities such as e-health and m-health can effectively promote disease monitoring and diagnosis, and various offline social participation activities can also play a role in regulating emotions. Therefore, Internet use and social participation factors may serve as relevant entry points for the development of intervention programs that may further improve the mental health of the visually impaired.

A remote group-mediated daylong physical activity intervention for older adults with chronic pain: Results of the MORPH-II randomized pilot trial

Chronic pain is a debilitating condition that affects many older adults who often have limited access to non-pharmacological pain management strategies. One potentially effective and novel lifestyle medicine for chronic pain involves increasing physical activity through frequent movement across the day, thereby also decreasing the presence of extended sedentary bouts. The MORPH-II pilot randomized controlled refinement trial iterated on the MORPH trial, which was a first-of-its-kind group-mediated daylong physical activity (DPA) intervention for older adults with chronic pain rooted in social cognitive and self-determination theories and supported by an mHealth toolset designed to foster social connection and awareness of physical activity patterns. MORPH-II was delivered fully remotely via videoconference software and supported by a technology kit comprising an iPad, activity monitor, and wireless weight scale. It was also implemented a refined coaching model designed to help participants better understand their own patterns of activity. A total of 44 participants were randomized to receive the 12-week group-mediated DPA intervention or to a low-contact control. Qualitative interviews suggest the program was well-received by participants and that participants developed an understanding of how patterns of physical activity related to their pain symptoms. Participants also highlighted several additional areas for refinement related to the coaching model and feedback provided within the mHealth app. Analyses of covariance, controlling for baseline values, revealed a small effect (η 2 = 0.01) on pain intensity favoring the intervention condition, though both groups improved during the study period. There was a large effect favoring the intervention condition on ActivPAL-assessed average daily steps (η 2 = 0.23) and postural shifts (η 2 = 0.24). Control participants spent less time in short sedentary bouts (η 2 = 0.09), and there was a small effect (η 2 = 0.02) indicating intervention participants spent less time in extended sedentary bouts. Finally, relative to control, intervention participants demonstrated a moderate improvement in autonomy satisfaction (η 2 = 0.05), relatedness frustration (η 2 = 0.05), and competence frustration (η 2 = 0.06), and a large magnitude improvement in competence satisfaction (η 2 = 0.22). These findings indicate that the MORPH-II intervention was feasible and acceptable, and may positively impact steps, postural breaks, and several key domains of basic psychological needs detailed in self-determination theory.

A Machine-Learning Based Approach for Predicting Older Adults' Adherence to Technology-Based Cognitive Training

Adequate adherence is a necessary condition for success with any intervention, including for computerized cognitive training designed to mitigate age-related cognitive decline. Tailored prompting systems offer promise for promoting adherence and facilitating intervention success. However, developing adherence support systems capable of just-in-time adaptive reminders requires understanding the factors that predict adherence, particularly an imminent adherence lapse. In this study we built machine learning models to predict participants' adherence at different levels (overall and weekly) using data collected from a previous cognitive training intervention. We then built machine learning models to predict adherence using a variety of baseline measures (demographic, attitudinal, and cognitive ability variables), as well as deep learning models to predict the next week's adherence using variables derived from training interactions in the previous week. Logistic regression models with selected baseline variables were able to predict overall adherence with moderate accuracy (AUROC: 0.71), while some recurrent neural network models were able to predict weekly adherence with high accuracy (AUROC: 0.84-0.86) based on daily interactions. Analysis of the post hoc explanation of machine learning models revealed that general self-efficacy, objective memory measures, and technology self-efficacy were most predictive of participants' overall adherence, while time of training, sessions played, and game outcomes were predictive of the next week's adherence. Machine-learning based approaches revealed that both individual difference characteristics and previous intervention interactions provide useful information for predicting adherence, and these insights can provide initial clues as to who to target with adherence support strategies and when to provide support. This information will inform the development of a technology-based, just-in-time adherence support systems.

Implementation practice models for development in low- and middle-income countries: systematic review of peer-reviewed literature

Introduction

This study operationally defines a relatively small, but growing field of study on implementation practice models for health behavior change in the context of international development. We define ‘implementation practice models’ as theoretical models that take a practical and practitioner-focused approach to behavior change, and we illustrate how these models have been developed and applied. The paper examines the continuum of behavioral theories and their application in the context of development programs and research in low- and middle-income countries (LMICs). We describe implementation practice models, examine how they have been used to design and evaluate theory-based interventions in LMIC, and describe the state of evidence in this field of study.

Methods

The authors conducted a systematic search of the published, peer-reviewed literature following the widely accepted PRISMA methods for systematic reviews. We aimed to identify all relevant manuscripts published in the English language in health, social science, and business literature that apply implementation practice models, located in an LMIC, with a behavior change objective. We located 1,078 articles through database searching and 106 through other means. Ultimately, we identified 25 relevant articles for inclusion.

Results

We found that the peer-reviewed literature on implementation practice models for development has been growing in recent years, with 80% of reviewed papers published since 2015. There was a wide range of different models revealed by this review but none demonstrated clear-cut evidence of being most effective. However, the models found in this review share common characteristics of focusing on the three central tenets of Opportunity, Ability, and Motivation (OAM).

Conclusions

This review found that implementation practice models for development are a promising and growing approach to behavior change in LMICs. Intervention practice models research should be expanded and applied in new domains, such as vaccination.

The role of age and opioid agonist treatment on substance use treatment completion in the United States

BACKGROUND

There is a large body of research indicating that substance use disorder treatment completion leads to higher rates of sustained recovery. However, not much is known about how age and opioid treatment programs (OTPs) OTPinteract to affect treatment completion. The purpose of this article is to better understand the pathway between age, OTP, and treatment completion.

METHODS

Data from the US 2017 Treatment Episodes Data Set was analyzed. Seemingly unrelated bivariate probit regression was used to determine whether OTP access mediates the relationship between age and treatment completion. We used propensity score matching to simulate the effects of a randomized control trial and to attenuate the likelihood of a Type 1 error.

RESULTS

Older adults have a higher likelihood than their younger counterparts of completing treatment regardless of OTP status in inpatient and outpatient settings. Those who received OTP in inpatient treatment had a 45% increased probability of completing treatment in detox settings and a 41% increased probability of completing treatment in inpatient settings. Older adults (age 50+) were more likely to receive OTP than their younger counterparts. There is a small but significant indirect effect of age on treatment completion in inpatient settings.

CONCLUSIONS

Older adults are more likely to receive OTP in both inpatient and outpatient settings. However, age does not appear to affect the probability of treatment completion when individuals receive OTP, except in inpatient settings. Implications are discussed.

Atp11b Deletion Affects the Gut Microbiota and Accelerates Brain Aging in Mice

The microbiota-gut-brain axis has attracted significant attention with respect to studying the mechanisms of brain aging; however, the specific connection between gut microbiota and aging remains unclear. The abnormal expression and mutation of proteins belonging to the P4-ATPase family, including Atp11b, results in a variety of neurological diseases. The results of our analysis demonstrate that there was a shift in the abundance of certain gut microbiota in Atp11b-knockout (KO) mice. Specifically, there was an increase in pro-inflammatory bacteria that accelerate aging and a decrease in probiotics that delay aging. Consequently, an enhanced oxidative stress response was observed, which was characterized by a reduction in the superoxide dismutase (SOD) activity and an increase in malondialdehyde (MDA) and reactive oxygen species (ROS) levels. In addition, our data demonstrate that there was a decrease in the number of cells in the dentate gyrus (DG) region of the hippocampus, and aggravation of aging-related pathological features such as senescence β-galactosidase (SA-β-Gal), p-HistoneH2AX (Ser139), and p16^INK4. Moreover, KO mice show typical aging-associated behavior, such as memory impairment and slow pain perception. Taken together, we demonstrate a possible mechanism of aging induced by gut microbiota in Atp11b-KO mice, which provides a novel perspective for the treatment of aging through the microbiota-gut-brain axis.

Risk Perception in the COVID-19 pandemic; a health promotion approach

BACKGROUND

Many measures have been taken so far to minimize the outbreak of COVID-19, but it is still unclear to what extent people have understood the risk. Public participation plays a vital role in better and effective control of the coronavirus, and the importance of risk perception is effective in their preventive behavior. The aim of this study was to investigate the pandemic risk perception of coronavirus disease after began of pandemic in Iranian society.

MATERIALS AND METHODS

This cross-sectional study was conducted in Iran in spring 2020. The data collection tool was a researcher-made questionnaire. The questions were extracted through interviews with experts and summarizing the opinions of public interviews, etc., The questionnaire was made available to the public through social media. The information was collected within 3 months. Quantitative data were reported as mean ± standard deviation and the qualitative data were reported as number and percent. Multiple linear regression and cross were also used to examine the demographic factors associated with risk perception. Data Analysis was performed using the SPSS version 21 statistical software.

RESULTS

In this study, 402 individuals from 28 provinces (Azarbaijan Gharbi, Azarbaijan Sharghi, Alborz, Ardabil, Bushehr, Chaharmahal and Bakhtiari, Esfahan, Fars, Ghazvin, Gilan, Golestan, Hamedan, Hormozgan, Ilam, Kerman, Kermanshah, Khorasan Razavi, Khorasan Shomali, Khuzestan, Kohgiluyeh and Boyerahmad, Kurdistan, Lorestan, Mazandaran, Semnan, Sistan and Baluchestan, Tehran, Yazd, and Zanjan) of Iran participated. The risk perception score obtained from the sum of the scores of the questions was classified into quartiles. Accordingly, the risk perception score of (22.9) 92 people was very low, (26.6) 107 people low, (26.9) 108 people moderate, and (23.6) 95 people high. The results of multiple linear regression showed that the variables of gender (P = 0.008) and occupation (P = 0.013) had a significant relationship with risk perception. There was no significant relationship between risk perception and variables of age, marital status, and level of education (P > 0.05).

CONCLUSION

The study showed that the risk perception of the people is more in categories of moderate to high. Assessing the risk perception of a pandemic can be helpful for preventive measurements and planning, and also, according to the results of the research, can be done appropriate educational interventions. Given that 47.5% of respondents were employees, of course, it should be noted that in sending a questionnaire virtually, there is usually a lot of loss and this is a limitation of the research. The results of this study can be useful in making prevention decisions and maintaining safety and health in the workplace.

The feasibility and efficacy of the home-based exercise programs in patients with cognitive impairment: A pilot study

OBJECTIVE

To examine the feasibility and efficacy of home-based aerobic and resistance exercise interventions for geriatric individuals with cognitive impairment.

METHODS

Fourteen participants with cognitive impairment were allocated to either the aerobic group (n = 8) or the resistance group (n = 6), after which they implemented a two-month home-based training program. Feasibility and efficacy outcomes were evaluated. A semi-structured interview was performed after the intervention.

RESULTS

All fourteen participants completed the two-month training program. The adherence rate was 0.94 for the aerobic group and 0.96 for the resistance group. No adverse events occurred. The results revealed a trend of group×time interaction effect on delayed recall. Significant group×time interaction effects were revealed on simple physical performance and body composition. Semi-structured interviews identified four motivators for participating in this program, four facilitators for and three barriers to keeping exercising, and some perceived benefits.

CONCLUSION

Home-based aerobic and resistance exercise programs are feasible for geriatric individuals with cognitive impairment. The efficacy needs to be further examined.

Longitudinal relationship of baseline functional brain networks with intentional weight loss in older adults

OBJECTIVE

The goal of this study was to determine whether the degree of weight loss after 6 months of a behavior-based intervention is related to baseline connectivity within two functional networks (FNs) of interest, FN1 and FN2, in a group of older adults with obesity.

METHODS

Baseline functional magnetic resonance imaging data were collected following an overnight fast in 71 older adults with obesity involved in a weight-loss intervention. Functional brain networks in a resting state and during a food-cue task were analyzed using a mixed-regression framework to examine the relationships between baseline networks and 6-month change in weight.

RESULTS

During the resting condition, the relationship of baseline brain functional connectivity and network clustering in FN1, which includes the visual cortex and sensorimotor areas, was significantly associated with 6-month weight loss. During the food-cue condition, 6-month weight loss was significantly associated with the relationship between baseline brain connectivity and network global efficiency in FN2, which includes executive control, attention, and limbic regions.

CONCLUSION

These findings provide further insight into complex functional circuits in the brain related to successful weight loss and may ultimately aid in developing tailored behavior-based treatment regimens that target specific brain circuitry.

The Effects of a Pain Management-Focused Mobile Health Behavior Intervention on Older Adults' Self-efficacy, Satisfaction with Functioning, and Quality of Life: a Randomized Pilot Trial

BACKGROUND

This report investigates the impact of a remote physical activity intervention on self-efficacy, satisfaction with functioning, and health-related quality of life (HRQOL) as assessed by the SF-36 in obese older adults with chronic pain. The intervention was group-mediated in nature and based in social cognitive theory and mindfulness-based relapse prevention.

METHODS

Participants (N = 28; 70.21 ± 5.22 years) were randomly assigned to receive either the active intervention, which focused on reducing caloric intake and increasing steps across the day or to a waitlist control condition.

RESULTS

Over 12 weeks, intervention participants reported a moderate, positive improvement in self-efficacy for walking relative to control. They also reported large magnitude improvements in satisfaction for physical functioning as well as improvements on pain and the physical functioning subscales of the SF-36.

CONCLUSIONS

These findings expand on previous research showing similar effects in response to structured exercise, this time via a protocol that is likely to be scalable and sustainable for many older adults. Additional work on larger and more diverse samples is warranted.

Postmenopausal women's adherence to pelvic floor muscle exercises over 2 years

OBJECTIVE

This study aimed to investigate women's adherence patterns to pelvic floor muscle exercises (PFME), their associated factors and within-pattern changes.

METHODS

This was a secondary analysis using data collected from 647 women aged 55 years and older in the USA. Women were randomly assigned to either a 2-h class group or an equivalent content 20-min DVD group to receive PFME complemented with adherence enhancement strategies. Adherence was assessed at 3, 12 and 24 months using three self-reported items matching PFME parameters. The k-mean clustering and multinomial logistic regression were used to investigate adherence patterns and their associated factors, respectively. Descriptive statistics were used for within-pattern changes over time.

RESULTS

Four adherence patterns, A, B, C and D, were identified. Women who displayed optimal adherence to all three aforementioned items, i.e. adherence pattern A, constituted 49.1%, 38.2% and 37.2% of women at 3, 12 and 24 months, respectively. Women with income > US$100,000 were more likely to display adherence pattern A within 12 months. Of women who had adherence pattern A at 3 months, 63.9% and 49.2% continued in this pattern at 12 and 24 months.

CONCLUSIONS

Fewer than half of women displayed adherence pattern A for 2 years. Early optimal adherence predicted women's subsequent optimal adherence.

Building on Lessons Learned in a Mobile Intervention to Reduce Pain and Improve Health (MORPH): Protocol for the MORPH-II Trial

BACKGROUND

Engaging in sufficient levels of physical activity, guarding against sustained sitting, and maintaining a healthy body weight represent important lifestyle strategies for managing older adults' chronic pain. Our first Mobile Health Intervention to Reduce Pain and Improve Health (MORPH) randomized pilot study demonstrated that a partially remote group-mediated diet and daylong activity intervention (ie, a focus on moving often throughout the day) can lead to improved physical function, weight loss, less pain intensity, and fewer minutes of sedentary time. We also identified unique delivery challenges that limited the program's scalability and potential efficacy.

OBJECTIVE

The purpose of the MORPH-II randomized pilot study is to refine the MORPH intervention package based on feedback from MORPH and evaluate the feasibility, acceptability, and preliminary efficacy of this revised package prior to conducting a larger clinical trial.

METHODS

The MORPH-II study is an iteration on MORPH designed to pilot a refined framework, enhance scalability through fully remote delivery, and increase uptake of the daylong movement protocol through revised education content and additional personalized remote coaching. Older, obese, and low-active adults with chronic multisite pain (n=30) will be randomly assigned to receive a 12-week remote group-mediated physical activity and dietary weight loss intervention followed by a 12-week maintenance period or a control condition. Those in the intervention condition will partake in weekly social cognitive theory-based group meetings via teleconference software plus one-on-one support calls on a tapered schedule. They will also engage with a tablet application paired with a wearable activity monitor and smart scale designed to provide ongoing social and behavioral support throughout the week. Those in the control group will receive only the self-monitoring tools.

RESULTS

Recruitment is ongoing as of January 2021.

CONCLUSIONS

Findings from MORPH-II will help guide other researchers working to intervene on sedentary behavior through frequent movement in older adults with chronic pain.

Applying social cognitive theory to predict physical activity and dietary behavior among patients with type-2 diabetes

INTRODUCTION

Non-communicable diseases, arising out of changing lifestyle habits of people, are the foremost causes of mortality and morbidity worldwide. Most of these diseases occur in low and middle-income countries. Chronic diseases can be managed with the help of health behaviors such as proper diet, physical exercise, adherence to medication, and avoidance of health risk behaviors such as smoking, alcohol consumption, sedentary lifestyle, etc. The social cognitive theory addresses the role of personal and environmental factors in an individual's health behavior. The current study aims to understand the role of social cognitive theory on physical activity and dietary behavior amongst individuals diagnosed with type-2 diabetes.

METHODS

A correlational study was conducted among 225 participants with type-2 diabetes, who are under medication. The data was collected using social cognitive questionnaire for physical activity & dietary behavior and Health-Promoting Lifestyle Profile II. Descriptive statistics, Pearson's correlation coefficient and multiple linear regression analysis were used to analyze the data.

RESULTS

It was found from the study results that, all the domains of social cognitive theory were significantly correlated with physical activity (p<0.001) and the SCT domains- self-regulation (p<0.001), social support (p<0.001), and outcome expectancy (p<0.05) were significantly correlated with dietary behavior. The results of multiple linear regressions indicated that the domains self- regulation and self- efficacy were the significant predictor for physical activity behavior (R2=.21, p ≤ 0.001) while the domains social support and self-regulation were the significant predictor of dietary behavior (R2=.09, p ≤ 0.001).

CONCLUSION

The study results show that there is an influence of social cognitive domains on physical activity and dietary behaviour. Further, this study suggests that social cognitive theory based intervention can be used to promote healthy behaviour.

Six-month changes in ghrelin and glucagon-like peptide-1 with weight loss are unrelated to long-term weight regain in obese older adults

BACKGROUND AND OBJECTIVE

Weight loss (WL) and subsequent regain are complex physiologic processes, and our understanding of the hormonal changes associated with these processes continues to evolve. We aimed to examine the effects of behavioral WL on 6-month changes in ghrelin and GLP-1 and evaluate the effects of these changes in gut hormones on weight regain among older adults.

SUBJECTS AND METHODS

One hundred seventy-seven obese (BMI: 33.5 (3.5) kg/m2) older adults (66.9 ± 4.7 years, 71.2% female, 67.6% white) were randomized to WL (WL; n = 68), WL plus aerobic training (n = 79), or WL plus resistance training (n = 75) for 18 months. Ghrelin, GLP-1, power of food scale (PFS), and weight were measured at baseline, 6 months, and 18 months.

RESULTS

There was no differential treatment effect on change in either gut hormone, however, there was a significant time effect across all groups (p < 0.001), with increases in ghrelin (∆ = +106.77 pg/ml; 95% CI = + 84.82, +128.71) and decreases in GLP-1 (∆ = -4.90 pM; 95% CI = -6.27, -3.51) at 6-month. Ratings on the PFS decreased from baseline to 6-month and there was significant loss of weight from baseline to either 6- or 18-month, ∆ = -7.96 kg; 95% CI = -7.95, -8.78 and ∆ = -7.80 kg; 95% CI = -8.93, -6.65, respectively (p < 0.001). Changes in ghrelin and GLP-1 at 6-month did not predict weight regain from 6- to 18-month.

DISCUSSION AND CONCLUSION

Among older adults with obesity and cardiometabolic disease, the intensive phase of dietary WL results in increasing levels of ghrelin and decreasing levels of GLP-1 that are unrelated to weight regain a year later. Registered with ClinicalTrials.gov (NCT01547182).

Associations of Body Dissatisfaction With Lifestyle Behaviors and Socio-Demographic Factors Among Saudi Females Attending Fitness Centers

OBJECTIVE

To examine body image perception and the associations of body dissatisfaction (BD) with socio-demographic and lifestyle factors among Saudi women attending fitness centers in Riyadh.

METHODS

Saudi females aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using stratified clustered sampling technique (n = 460). Height and weight were measured to calculate actual body mass index (BMI). A previously validated instrument was used to collect socio-demographic and lifestyle variables including physical activity (PA), sedentary behaviors, sleep and dietary habits. Stunkard Figure Rating Scale silhouettes were used to assess perceived and desired body shape.

RESULTS

The participants had a mean (SD) age of 29.2 (8.2). The majority were not married (57%), with no children (66%) and had college degrees (78%). While 63% were overweight or obese, nearly 40% of women underestimated their perceived body shape. The majority of respondents (87%) were dissatisfied with their body shape including 68% of normal weight women. Females who had BD were significantly older, had higher BMI, reported more weight loss attempt and had expended less time in vigorous (p = 0.033) and total (p = 0.042) PA than those who were satisfied with their body shape. However, when adjusting for socio-demographic variables, logistic regression analysis revealed significant associations of BD with higher BMI, shorter membership duration of fitness club, and reduced dairy products and energy drinks consumption.

CONCLUSION

Except for BMI and decreased dairy products and energy drinks consumption, many lifestyle behaviors did not associate with BD among Saudi females attending fitness centers. The findings can inform healthcare providers when intervention strategy is implicated for females with BD. Future studies should compare the associations of BD with lifestyle behaviors between males and females attending fitness centers and seeking weight loss.

Functional Brain Networks: Unique Patterns with Hedonic Appetite and Confidence to Resist Eating in Older Adults with Obesity

OBJECTIVE

The purpose of this study was to determine whether baseline measures of hedonic hunger-the Power of Food Scale-and self-control for food consumption-the Weight Efficacy Lifestyle Questionnaire-were associated with network topology within two sets of brain regions (regions of interest [ROIs] 1 and 2) in a group of older adults with obesity. These previously identified brain regions were shown in a different cohort of older adults to be critical for discriminating weight loss success and failure.

METHODS

Baseline functional magnetic resonance imaging data (resting state and food cue task) were collected in a novel cohort of 67 older adults with obesity (65-85 years, BMI = 35-42 kg/m² ) participating in an 18-month randomized clinical trial on weight regain.

RESULTS

The Power of Food Scale was most related to ROI 1, which includes the visual cortex and sensorimotor processing areas during only the food cue state. During both the food cue and resting conditions, the Weight Efficacy Lifestyle Questionnaire was associated with ROI 2, which includes areas of the attention network and limbic circuitry.

CONCLUSIONS

Our findings show critical, distinct links between brain network topology with self-reported measures that capture hedonic hunger and the confidence that older adults have in resisting the consumption of food because of both intrapersonal and social/environmental cues.

Promoting Active Aging: Lessons Learned in an Implementation Pilot in Primary Care

BACKGROUND

Physical activity (PA) preserves mobility, but few practices screen older adults for mobility impairment or counsel on PA.

DESIGN

"Promoting Active Aging" (PAA) was a mixed-methods randomized-controlled pilot, to test the feasibility and acceptability of a video-based PA counseling tool and implementation into practice of two mobility assessment tools.

SETTING

Three primary care practices affiliated with Wake Forest Baptist Health.

PARTICIPANTS

Adults aged 65 years and older who presented for primary care follow-up and were willing and able to answer self-report questions and walk 4 meters (n = 59).

INTERVENTION

Video-based PA counseling intervention versus control video, "Healthy Eating."

MEASUREMENTS

Potential participants completed mobility assessments: self-report (Mobility Assessment Tool-short form (MAT-sf)) and performance based (4-meter walk test). We assessed PAA's implementation-feasibility, acceptability, and value-via interviews and surveys. Effectiveness was measured via participant attendance at a PA information session.

RESULTS

Of 92 patients approached, 89 (96.7%) agreed to mobility assessment. Eighty-nine completed MAT-sf, and 97.8% (87/89) completed 4-meter walk test. Sixty-seven (75%) met eligibility criteria, and 59 (88%) consented to be randomized either to the PA counseling intervention (Video-PA) or to active control (Video-C). Most participants viewed the walk test positively (51/59; 86.4%). Staff reported that completion of patient surveys, MAT-sf, and videos required significant staff time and support (median = 26 minutes for all), resulting in low acceptability of MAT-sf and the videos. Attendance at a PA information session did not differ by randomization group (Video-PA = 11/29 (37.9%); Video-C = 12/30 (40%); 95% confidence interval for difference in proportion = -0.29 to 0.25).

CONCLUSIONS

Mobility assessment, particularly a 4-meter walk test, was feasible in primary care. Tablet-based assessment (MAT-sf) and video counseling tools, selected to reduce staff effort, instead required significant time to implement. Future work to promote PA should identify effective ways to facilitate adoption of PA in sedentary older adults that do not burden staff.

Using behavioral science theory to enhance public health nursing

The application of behavioral science theory is instrumental in advancing nursing research and practice. Nurses can benefit from a thorough understanding of theoretical perspectives related to health behavior change. Behavioral science theory can provide a conceptual context for understanding patient behavior, it can guide research on the determinants of health behavior and health service delivery, and it can offer alternative approaches to nursing practice that may improve the effectiveness of patient care. The aim of this paper is to provide some examples of behavioral theories that can be used in nursing research and practice, and provide an example of how one theory, Stages of Change (Transtheoretical Model), can be applied to older adult fall prevention. Given the critical role behavior plays in premature morbidity and mortality, public health nurses and researchers can benefit by broadening the use of theory in the design and implementation of interventions, using behavioral theory as their guide.

Effects of health beliefs, social support, and self-efficacy on sun protection behaviors among medical students: testing of an extended health belief model

Sun protection behaviors (SPB) are important modifiable risk factors for skin cancer. As the most common malignancies in the world, skin cancers account for significant morbidity, mortality, and economic burden. Physicians play a key role in educating patients about proper SPB. Medical education provides the foundation for physician understanding of SPB and future patient education. The Health Belief Model (HBM) is a theoretical model that offers constructs to help explain health behaviors. This cross-sectional study examined a convenience sample of 186 medical student to assess their engagement in SPB through the lens of the 6 HBM constructs and social support. Overall, we found engagement in SPB among our cohort to be low. About 70.4% report never using wide-brimmed hats and only 44.6% often or always use sunscreen. Hierarchical multiple regressions were performed in three blocks to analyze the relationship between the independent variables (HBM constructs and social support) and dependent variable (SPB) after controlling for the influence of demographic covariates. In our health constructs model, beliefs about susceptibility, benefits minus barriers, and self-efficacy were found to be significant predictors of engaging in SPB. Addition of social support in the final model did not significantly improve prediction of SPB engagement. These findings support use of educational programs based on HBM for the improvement of SPB among medical students.
