Malnutrition–Sarcopenia Syndrome and Self-Management Behaviors in Continuing-Care Retirement Community Residents

Associations Between Components of Self-Management Theory and Falls Among Older Adults

PURPOSE

To examine the relationship of key individual and family self-management theory (IFSMT) components, including self-management process variables on proximal (self-management behaviors) and distal (falls) outcomes in older adults.

METHOD

A secondary data analysis was conducted using data of 99 older adults living in continuing care retirement communities in the U.S. Midwest. Descriptive statistics, multiple regression, and logistic regression were performed to analyze the data.

RESULTS

The multiple regression model demonstrated a positive association between self-efficacy for physical activity and steps per day. The logistic regression model showed that high expectations regarding aging are associated with reduced likelihood of meeting daily protein intake.

CONCLUSION

Key components of the IFSMT, such as self-efficacy, steps per day, and expectations regarding aging, are important when designing self-management interventions to prevent falls. [Journal of Gerontological Nursing, 50(8), 19-28.].

A Concept Analysis of Self-Management of Physical Frailty

This review aimed to clarify the concept of self-management in the context of physical frailty and to provide insights that support the development of interventions to prevent physical frailty. A concept analysis using thirty-three studies was performed, six attributes of the concept "self-management of physical frailty" were identified: {Cooperating with healthcare professionals or familiar persons}, {Investing and managing in resources}, {Acquisition and maintenance of individualized self-management strategies}, {Self-directed process}, {Goal setting and personalized action planning} and {Living with one's own health condition with a positive attitude}. Self-management of physical frailty can be defined as a process in which an individual independently sets goals and action plans, engages in strategies such as exercise and nutritional management, and lives with one's own health condition with a positive attitude by collaborating with healthcare professionals and others, in addition to utilizing resources. To support the process in which an individual independently sets goals and action plans, engages in strategies, self-management support based on learning theories that lead to cognitive, emotional, and behavioral changes is necessary.

The association between sedentary behaviour and sarcopenia in older adults: a systematic review and meta-analysis

BACKGROUND

Sedentary behaviour is considered to contribute to sarcopenia when combined with physical inactivity. Whether sedentary behaviour is independently associated with sarcopenia remains controversial. The aim of this study is to explore the association between sedentary behaviour and sarcopenia in older adults in community and long-term care facility settings.

METHODS

Eight electronic databases including MEDLINE, PsycINFO, Wanfang were searched from inception until August 2023. The review included cross-sectional and longitudinal studies concerning the association between sedentary behaviour and sarcopenia among participants over 60 years old. Evidence was pooled by both random-effects meta-analysis and narrative synthesis. Subgroup analyses explored variation according to adjustment of physical activity, settings, and measurements of sedentary behaviour and sarcopenia. Quality assessment for individual studies was performed with the Joanna Briggs Institute (JBI) Critical Appraisal Checklist.

RESULTS

Seventeen articles (16 cross-sectional studies and 1 longitudinal study) of 25,788 participants from community or long-term care facility settings were included. The overall quality of the included studies was rated high. Meta-analysis of 14 cross-sectional studies showed that sedentary behaviour was independently positively associated with sarcopenia: pooled odd ratio 1.36 (95% confidence interval, 1.18-1.58). The independent positive association remained in subgroup analyses by adjustment of physical activity, settings, and measurements of sedentary behaviour and sarcopenia. The narrative analysis corroborated the findings of the meta-analysis and provided additional evidence suggesting that interruptions in sedentary periods were linked to a decreased likelihood of developing sarcopenia.

CONCLUSIONS

The findings support the hypothesis that sedentary behaviour is independently positively associated with sarcopenia in older adults, providing vital indications for the development of strategies to prevent sarcopenia.

Nutritional Status and Risk of Sarcopenia among Hospitalized Older Adults Residing in a Rural Region in Turkey

BACKGROUND

This study aimed to determine the prevalence of sarcopenia and its associated factors in community-dwelling older adults at risk of malnutrition based on the Mini Nutritional Assessment (MNA), Prognostic Nutritional Index (PNI), and Geriatric Nutritional Risk Index (GNRI).

METHODS

The study participants were 345 adults aged >65 years who visited Geriatric Internal Medicine outpatient clinics. The study included people without acute illness for whom the risk of malnutrition could be assessed and appropriate measurements taken. At the baseline visit, participants' data and measurements were gathered. The primary data included sociodemographic details, anthropometric measurements, malnutrition screening tests, and functional assessments.

RESULTS

The participants' mean age was 76.21±5.59 years, and 57.1% were men (n=97). The prevalence rate of sarcopenia was 45.5%. Compared to individuals without sarcopenia, those with it were older; had lower MNA, PNI, and GNRI scores; and had lower muscle mass, muscle strength, and lower leg circumferences (p<0.001). After adjusting for potential confounding factors, we found that sarcopenia, advanced age, male sex, high risk of malnutrition, calf circumference, and a low PNI score were all significantly associated with a low GNRI score (p<0.001).

CONCLUSION

Sarcopenia was significantly associated with advanced age, male sex, and high risk of malnutrition. Patients' nutritional and functional status should always be assessed for therapeutic interventions and lifestyle changes.

Multivitamin/Multimineral Supplementation Prevents or Reverses Decline in Vitamin Biomarkers and Cellular Energy Metabolism in Healthy Older Men: A Randomized, Double-Blind, Placebo-Controlled Study

Despite the reported prevalence of micronutrient deficiencies in older adults, it is not yet established whether multivitamin/multimineral (MV/MM) supplements improve blood micronutrient status in individuals over the age of 65. Therefore, a cohort of 35 healthy men (>67 years) was recruited for an MV/MM supplementation trial. The primary endpoint was, as an indicator of micronutrient status, changes in blood micronutrient biomarkers from baseline to at least six months of supplementation with MV/MM or placebo. The secondary endpoint was basal O2 consumption in monocytes as an indicator of cellular metabolism. MV/MM supplementation improved blood concentrations of pyridoxal phosphate, calcifediol, α-tocopherol, and β-carotene concentrations throughout the cohort. By contrast, those in the placebo group generally showed declines in blood vitamin concentrations and an increased prevalence of suboptimal vitamin status during the study period. On the other hand, MV/MM supplementation did not significantly affect blood mineral concentrations, i.e., calcium, copper, iron, magnesium, and zinc. Interestingly, MV/MM supplementation prevented the decline in monocyte O2 consumption rate. Overall, MV/MM use improves or prevents declines in vitamin, but not mineral, status and limits declines in cellular O2 consumption, which may have important implications for metabolism and immune health in healthy older men.

Internet+Continuous Nursing Mode in Home Nursing of Patients with T-Tube after Hepatolithiasis Surgery

This study was to explore the effect of a continuous nursing model based on the mobile Internet in the home nursing of patients with T-tube after hepatolithiasis surgery. A continuous nursing system based on the mobile Internet was constructed, and 94 discharged patients with T-tube after biliary tract surgery were selected as the study subjects. The differences of complication rate, referral rate, nursing satisfaction, self-care ability, and quality of life score through the 36-item short form health survey (SF-36) after routine health education nursing (control group, n = 47) and continuous nursing mode based on the Internet (observation group, n = 47) were explored. The results showed that the success rate of the continuous nursing system based on mobile Internet in processing user requests was 96.2%. After nursing, the total complication rates of the control group and the observation group were 34.0% and 6.4%, the total satisfaction rates were 42.6% and 87.2%, and the referral rates were 23.4% and 6.4%, respectively, and the difference was statistically significant (P < 0.05). After nursing, the scores of self-care ability and SF-36 quality of life in the observation group were higher than those in the control group, and the difference was statistically significant (P < 0.05). In summary, the continuous nursing platform based on mobile Internet technology can meet the needs of users, and the nursing mode can significantly improve the home self-care ability of discharged patients with T-tube after surgery and improve the nursing effect, which is conducive to the rehabilitation of patients.
