Association of Nutritional Status with Physical Function and Disability in Community-Dwelling Older Adults: A Longitudinal Data Analysis

Sex differences in clinical presentation, treatment response, and side effects of nutritional therapy among patients at nutritional risk: a secondary analysis of the randomized clinical trial EFFORT

BACKGROUND

Considering sex-specific factors has become an increasingly recognized area for research and practice, in the field of clinical nutrition, there is insufficient evidence regarding differences in clinical presentation, treatment response, and side effects of nutritional therapy among female and male patients.

OBJECTIVES

We hypothesized that the clinical presentation, response to nutritional therapy, and side effects from the intervention would differ in the two sexes.

METHODS

This secondary analysis investigated differences among female and male patients at risk for malnutrition regarding initial presentation, clinical outcomes, and treatment response in patients included in the Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), a randomized controlled trial comparing individualized nutritional support to usual care.

RESULTS

Of 2028 patients included in the trial, 964 were females and 1064 were males. The nutritional history and clinical presentation of female patients was different: they consumed less food and had a greater loss of appetite than the male population. Male patients had higher risk for mortality at 180 d [27% compared with 19%; adjusted hazards ratio (HR): 1.35; 95% CI: 1.12, 1.63] and further adverse clinical outcomes. However, there was no difference in the effect of nutritional support on mortality among female and male patients (HR: 0.76; 95% CI: 0.45, 1.27, compared with HR: 0.81; 95% CI: 0.54, 1.21, respectively; P-interaction = 0.939).

CONCLUSIONS

Results of this multicenter randomized trial suggest that multimorbid female inpatients have a different clinical presentation and are more prone to loss of appetite and reduced daily dietary intake than male inpatients. Importantly, the favorable response to nutritional interventions was similar in both sexes. This trial was registered at clinicaltrials.gov as NCT02517476.

Nutritional status of older adults in India: An exploration of the role of oral health and food insecurity factors

Background

In this study, we attempted to generate insights into the determinants of nutritional status among older adults in India by exploring the role of factors including oral health, food insecurity, socioeconomic, demographic and health-related variables. The study also examined the moderating role of tooth loss with the association between chewing ability and nutritional status.

Methods

The data was obtained from Longitudinal Ageing Study India (LASI) - Wave 1 (2017-18). The sample consisted of 27,411 older adults (Male = 13, 232; Female = 14, 179) aged 60 years and above. In addition to descriptive and bivariate analysis, we employed multinominal logistic regression analysis.

Result

There was a significant association between the ability to chew solid food and tooth loss in the nutritional status of older adults. It was further revealed that tooth loss acted as a moderator (aRRR = 1.50, 95 % CI: 1.08-2.08) between the chewing ability and the risk of being underweight. The weight loss due to food insecurity increased the relative risk ratio of being underweight (aRRR = 1.58, 95 % CI: 1.25-2.00). Further evidence showed that self-rated health (SRH), Instrumental Activities of Daily Living (IADL), morbidity status and socioeconomic factors had a significant role in determining the nutritional status among older adults.

Conclusion

Chewing ability, tooth loss, and food insecurity determine nutritional status among older adults. It is suggested to care for oral and general physical health as these factors increase the risk of nutritional deficits. Also, policy measures should be strengthened to address the specific health and food security needs of older adults from vulnerable socioeconomic circumstances.

Prevalence of Undernutrition in Community-Dwelling Older Adults in The Netherlands: Application of the SNAQ65+ Screening Tool and GLIM Consensus Criteria

The aim of this study was to provide recent data on the prevalence of undernutrition based on screening and diagnosis in Dutch community-dwelling older adults. The data from the 2021 to 2022 examination wave from the Longitudinal Aging Study Amsterdam (n = 1138) and the Dutch National Food Consumption Survey 2019-2021 (n = 607) on community-dwelling men and women aged 65 years and older were used. The prevalence of undernutrition was based on a positive score on the Short Nutritional Assessment Questionnaire 65+ (SNAQ65+) screening tool, a positive diagnosis using the Global Leadership Initiative on Malnutrition (GLIM) criteria and their combination. Of the combined sample (n = 1745), the mean age was 74 (SD 6) years, where 16.7% were aged 80 years or older, 50.5% was female, 56.9% had a high education level, and 30.3% lived alone. The prevalence of undernutrition based on the SNAQ65+ screening in the combined sample was 8.5% (95% CI 7.3-9.9%). In the subgroup of LASA participants with complete data on all GLIM criteria (n = 700), the prevalence of undernutrition was 5.4% based on SNAQ65+ and 7.1% based on GLIM. A positive SNAQ65+ screening followed by a positive GLIM diagnosis resulted in a lower prevalence (3.1%). Being female, older, living alone, receiving formal home care, and having poor self-rated health, poor appetite, or mobility limitations, they were all associated with a higher prevalence, with more than two-fold higher prevalence rates in some subgroups. The results show that currently one out of twelve community-dwelling adults aged 65 years and older is undernourished based on the SNAQ65+ screening, and one out of fourteen is undernourished based on the GLIM diagnosis criteria. Awareness is needed to increase early recognition and treatment in community and primary care, especially among the more vulnerable groups.

Interaction between malnutrition and physical disability in older adults: is there a malnutrition-disability cycle?

Malnutrition and physical disability are urgent issues in super-aging societies and the 2 phenomena are closely linked in older adults. Both conditions have common underlying causes, including physiological changes due to aging and burdens imposed by disease or injury. Accordingly, a concept of the malnutrition-disability cycle was generated and a comprehensive literature search was performed. There was insufficient evidence to prove an interrelationship between malnutrition and physical disabilities, because of the study design and poor quality, among other factors. However, some evidence exists for the interaction between low body mass index and swallowing disorders, and the effects of some malnutrition and disability components. This review provides the rationale for this interaction, the concept of a malnutrition-disability cycle is proposed, and the available evidence is critically appraise.

Sensory-Enhanced, Fortified Snacks for Improved Nutritional Intake Among Nursing Home Residents

The present study aimed to determine if providing sensory-enhanced, fortified snacks changed nutrient consumption among nursing home residents. Nursing home residents were provided typical facility snacks or sensory-enhanced, fortified snacks across two separate 8-week time blocks. The enhanced snack supplements included quick-dissolving (transitional-state) crisps, puree dips, and dry soup blends that are intended to be accessible for individuals with a wide range of masticatory and swallowing abilities (e.g., oral frailty). Snacks were weighed before and after sessions using a food scale. Calories, fat, carbohydrates, protein, sodium, sugar, and fiber consumed were calculated daily. Despite consuming a smaller percentage of snack weight, participants consumed increased protein and fat, and fewer carbohydrates and sugar in the enhanced snack condition, with no significant difference in caloric intake. Sensory-enhanced, fortified snacks may be viable options for increasing the quality of nutritional intake among nursing home residents, particularly in light of decreased quantity of intake.

Individually tailored nutritional guidance improved dietary intake of older family caregivers: a randomized controlled trial

PURPOSE

Older family caregivers (FCs) are vulnerable to insufficient dietary intake and risk of malnutrition. The aim of this study was to assess the impact of individually tailored nutritional guidance on the dietary intake and nutritional status of older FCs and their care recipients' (CRs') nutritional status.

METHODS

This study was a randomized controlled 6-month nutrition intervention in Eastern Finland. The inclusion criteria for FCs were having a home-living CR aged 65 or above and a valid care allowance. The exclusion criterion was CR receiving end-of-life care at baseline. Participants were randomly assigned to an intervention (FCs n = 63, CRs n = 59) and a control (FCs n = 50, CRs n = 48) group. Individually tailored nutritional guidance targeted to FCs was given to an intervention group by a clinical nutritionist. The main outcomes were dietary intake (3-day food record).

RESULTS

After the 6-month intervention, 63 FCs and 59 CRs in the intervention group and 50 FCs and 48 CRs in the control group were analyzed. In the intervention group of FCs, the intakes of protein, riboflavin, calcium, potassium, phosphorus, and iodine differed significantly (p < 0.05) compared to the control group. In addition, the intake of vitamin D supplementation improved in the intervention group of the FCs and CRs (p < 0.001).

CONCLUSION

Individually tailored nutrition guidance improves the intake levels of crucial nutrients, such as the intake levels of protein, vitamin D, and calcium of the FCs. Further studies are warranted to optimize the methods to improve the nutrition of FCs. Registration number of Clinical Trials: ClinicalTrials.gov NCT04003493 (1 July 2019).

The Nutritional Status of Long-Term Institutionalized Older Adults Is Associated with Functional Status, Physical Performance and Activity, and Frailty

Among older adults living in long-term nursing homes (LTNHs), maintaining an adequate functional status and independence is a challenge. Whilst a poor nutritional status is a potential risk factor for a decreased function in this population, its role is not fully understood. Here, using a transversal multicenter study of 105 older adults living in 13 LTNHs, we analyzed the associations between nutritional status, as measured by the Mini Nutritional Assessment (MNA), and the parameters of functional status, physical performance, physical activity, and frailty as well as comorbidity and body composition. The MNA scores were positively correlated with the Barthel Index, handgrip strength, Short Physical Performance Battery (SPPB) scores, absolute muscle power, and Assessment of Physical Activity in Frail Older People (APAFOP) scores and were negatively correlated with dynamic balance and frailty. In a multiple linear regression model controlling for gender and age, the APAFOP score (β = 0.386), BMI (β = 0.301), and Barthel Index (β = 0.220) explained 31% of the variance in the MNA score. Given the observed close relationship between the MNA score and functional status, physical performance and activity, and frailty, interventions should jointly target improvements in both the nutritional status and functional status of LTNH residents. Strategies designed and implemented by interdisciplinary professional teams may be the most successful in improving these parameters to lead to better health and quality of life.

Associations between physical activity levels with nutritional status, physical fitness and biochemical indicators in older adults

BACKGROUND & AIMS

A sedentary lifestyle is one of the major health concerns of all societies that is associated by an increased risk of cardiovascular diseases. In this regard, we compared the anthropometric parameters, physical fitness (PF), lipid profile, and nutritional status of older adults with different levels of physical activity (PA).

METHODS

In this cross sectional study, 220 older people (age: 67.39 ± 2.08 yrs) according to their PA levels had been categorized at high (n = 72), moderate (78) and low (n = 70) PA groups. The International Physical Activity Questionnaires and food frequency questionnaire has been used to determine the PA and nutritional status, respectively. Waist and hip circumference, height, weight, and body mass index of subjects were measured and calculated. Both lower and upper body strength, flexibility, static and dynamic balance, and endurance performance factors were used to determine the level of PF. To assess blood biochemical factors, subjects were asked to visit the laboratory after 12 h of fasting.

RESULTS

The results showed waist circumference, hip circumference, and body fat percent were significantly lower in the high PA group compared to the low PA group in both males and females (P ≤ 0.05). Upper body strength, lower body strength, static balance, dynamic balance flexibility and endurance were significantly better in the high PA group compared to the low PA group in both males and females (P ≤ 0.05). Moreover, triglyceride was significantly lower in the high PA group compared to the low PA group in both males and females (P ≤ 0.05). According to the post hoc results, high-density lipoprotein, low-density lipoprotein and fasting glucose were significantly better in the high PA group compared to the low PA group in both males and females (P ≤ 0.05). All participants regardless PA levels showed insufficient consumption of zinc, calcium, vitamin E, and vitamin D (P ≤ 0.05). On the other hand, carbohydrate, sodium, iron, vitamin C and niacin intake significantly above recommended dietary allowance (P ≤ 0.05).

CONCLUSIONS

The results of the current work showed that a higher level of PA improved anthropometric indicators, PF, and lipid profile in Iranian older adults. Moreover, older nutrition should be monitor to maintain their physical health and to prevent them from developing chronic diseases and their malnutrition complications.

The Gender-Specific Relationship between Nutritional Status, Physical Activity and Functional Mobility in Irish Community-Dwelling Older Adults

Research suggests that both nutrition and physical activity can protect mobility in older adults, but it is yet to be determined whether these relationships are affected by gender. Thus, we investigated the gender-specific relationship between nutritional status, physical activity level and functional mobility in Irish older adults. A cross-sectional study was undertaken in 176 community-dwelling older adults (73.6 ± 6.61 years) living in Cork, Ireland. Nutritional status was measured using the Mini Nutritional Assessment-Short Form (MNA-SF) and physical activity was assessed via the Physical Activity Scale for the Elderly (PASE). Functional mobility was measured using the Timed Up and Go (TUG) test. The gender-stratified relationship between variables was assessed using Pearson's correlations and multiple linear regression. Partial correlations (p < 0.05) were observed for TUG with PASE score in both genders, and with MNA-SF score in females, only. Multiple regression showed that physical activity was a predictor of TUG in both genders (β = 0.257 for males, β = 0.209 for females, p < 0.05), while nutritional status was a predictor of TUG in females, only (β = -0.168, p = 0.030). Our results suggest that physical activity is associated with functional mobility in both genders, while the relationship between nutritional status and mobility may be specific to older females. These findings may be of interest for the design of functional preservation strategies.
