The impact of weight loss and low BMI on mortality of nursing home residents – Results from the nutritionDay in nursing homes

Nursing Home Organization Mealtimes and Staff Attitude Toward Nutritional Care: A Multicenter Observational Study

OBJECTIVES

The aims of this study were to investigate the practices of registered nurses and nurse aides at mealtimes in nursing homes (NHs) and to evaluate the attitudes of health care staff toward the nutritional care of older people.

DESIGN

This is a multicenter cross-sectional study.

SETTING AND PARTICIPANTS

The study involved a convenience sample of NH health care staff: physicians, registered nurses, and nurse aides.

METHODS

Data were collected on characteristics of the dining environment, organizational and nutritional care practices, staff-resident ratio, and staff activities during meals, using 2 questionnaires and staff attitudes were assessed with Staff Attitudes to Nutritional Nursing Care Geriatric Scale (SANN-G). Total score ranges from 18 to 90 points, with the following cutoffs: ≥72, positive attitude; ≤54, negative; and 55-71 points, neutral attitude.

RESULTS

A total of 1267 workers from 29 NHs in northern Italy participated in the study. The most common nutritional assessment tool used by nurses was the Malnutrition Universal Screening Tool. A median of 4.0 and 4.2 people (family caregivers, volunteers and staff) were present for feeding support, respectively, at lunch and dinner. A median of 2.5 and 2.0 staff members at lunch and at dinner, respectively, fed residents. Overall, 1024 health care workers responded to SANN-G of which 21.9% showed a negative attitude, 57.2% neutral, and 20.9% a positive attitude. Nurse aides (190/714) showed worse attitudes compared with registered nurses (20/204) and physicians (2/36); differences were statistically significant. Overall, the best attitudes were toward "habits," "interventions," and "individualization" of nutritional care. Staff who had received nutritional training (29.2%) had best attitudes.

CONCLUSIONS AND IMPLICATIONS

The results suggest that NHs should ensure adequate staff-resident ratio during meals, involving trained volunteers and relatives. Moreover, health professionals' knowledge and attitude toward nutritional care should be improved through continuous training.

Malnutrition as a prognostic factor for 2-year mortality in hospitalized patients in Norway: A matched cohort study

BACKGROUND

Risk of malnutrition and malnutrition have been previously associated with increased risk of mortality. It remains unclear, however, whether the severity of malnutrition differentiates in association with all-cause mortality. The aim was to assess the association between being at risk of malnutrition or being diagnosed with malnutrition according to the diagnostic assessment of the Global Leadership Initiative on Malnutrition (GLIM) with all-cause mortality during a 2-year follow-up in hospitalized patients.

METHODS

A matched cohort study was conducted in hospitalized patients (excluding cancer, intensive care, and transmissible infections) at a university hospital in Bergen, Norway. All patients underwent nutrition screening with the Nutritional Risk Screening 2002 and a further nutrition assessment using the GLIM criteria. All-cause mortality was estimated from the Norwegian death registry after 2 years, and risk factors were calculated by Cox regression analysis.

RESULTS

Among 326 patients included, 55 patients died within 2 years (17% mortality rate). Risk of malnutrition was associated with increased all-cause mortality, which disappeared after adjustment for age and sex. Malnutrition was associated with an increased risk of all-cause mortality at 2 years also after adjustment for age and sex and, additionally, for further comorbidities (hazard ratio = 2.50; 95% CI, 1.41-4.42). When analyzed separately only severe malnutrition was associated with mortality (hazard ratio = 2.73; 95% CI, 1.44-5.15).

CONCLUSION

The findings highlight a strong association between inpatients with severe malnutrition, defined by the GLIM criteria, and an increased risk of all-cause mortality within a 2-year follow-up.

Relationship between nutritional status and clinical outcomes among older individuals using long-term care services: A systematic review and meta-analysis

BACKGROUND & AIMS

Nutritional status is a significant issue in an aging society; however, the impact of the nutritional status of older individuals using long-term care services on the caregiving burden remains unclear. This systematic review and meta-analysis aimed to investigate the impact of nutritional issues on adverse outcomes in older individuals using long-term care services.

METHODS

We used data from the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Web of Science, CINAHL, and Ichu-shi Web databases. Original articles published in English or Japanese between January 2000 and July 2022 were included. The inclusion criteria were interventional and observational studies on individuals using long-term care services with aged ≥65 years and a focus on body weight or weight loss. Data on adverse outcomes related to caregiving burden, including the number of people requiring care, mortality, complications, activities of daily living (ADL), and quality of life, were collected.

RESULTS

The literature search yielded 7873 studies, of which 35 were ultimately included. Seven observational studies investigated mortality outcomes, and seven examined ADL outcomes. The meta-analysis revealed significantly higher mortality rates in individuals classified as underweight (BMI <18.5 kg/m2) than in those with BMI ≥18.5 kg/m2 (risk ratio [RR] 1.49; 95 % confidence interval [CI] 1.31 to 1.73, 0.22; I2 93 %). Further, on categorising the participants based on a BMI cutoff of 25 kg/m2, those with a BMI of <25 kg/m2 had a significantly increased mortality rate (RR 1.21; 95 % CI 1.04-1.40; I2 = 98 %). BMI and weight loss did not affect ADL.

CONCLUSIONS

Our findings indicate that underweight and weight loss are significantly associated with increased mortality in older individuals using long-term care services. Therefore, appropriate weight management is recommended for this population. However, further research is necessary owing to the high heterogeneity observed in this study.

Predictors of malnutrition among older residents in Qatari long-term care facilities: a retrospective study

BACKGROUND

Malnutrition is a prevalent issue among older adults in long-term care facilities and is associated with adverse health outcomes and increased healthcare costs. Identifying the predictors of malnutrition in this population is crucial for developing effective intervention strategies. This study aimed to explore the factors contributing to malnourishment among older individuals living in long-term care facilities in Qatar.

METHODS

This cross-sectional study included 75 older adults from two long-term care facilities (Rumailah Hospital and Enaya Specialized Care Center) in Qatar. Baseline characteristics, including age, sex, length of stay, mortality, weight, body mass index, co-morbidities, and laboratory parameters, were assessed. Data were analyzed using the most recent version of the SPSS software, version 29. Predictors of malnutrition and mortality were identified using logistic regression analysis.

RESULTS

Of the 75 older individuals included in the study, 85% (64) were malnourished. The average age of the participants was 74.89 years, with a standard deviation of 10.21. Of all participants, approximately 61% (46) were males, and 39% (29) were females. Most malnourished older adults were classified as either at "moderate (29.69%)" or "severe risk (37.50%)," according to the Geriatric Nutritional Risk Index. Malnourished participants experienced a significant percentage of weight change within 3 months (14.01 ± 7.89); the only statistically significant predictor of malnutrition was the percentage of weight change within 3 months with an odds ratio (OR) of 4.8 (confidence interval [CI] 1.56-14.75) and p-value of 0.006. Statistically significant predictors of mortality were malnutrition (OR 24.84, CI 1.09-564) and age (OR 1.07, CI 1.00-1.14).

CONCLUSIONS

A significant predictor of malnutrition in older adults identified in this study was the sudden and recent change in weight, which can be employed to detect individuals at risk early and guide tailored interventions. Malnutrition is a significant predictor of mortality. Employing a multidimensional strategy to tackle malnutrition can improve outcomes for the older individuals.

Ratio of waist circumference to body mass index: A novel predictor of clinical outcome in hypertension patients

We aim to investigate the influence of waist circumference and body mass index (BMI) on all-cause death and cardiovascular-specific death in patients with hypertension. This prospective cohort study, based on waist circumference and body mass index measurements in patients with hypertension, provided risk estimates of all-cause mortality and cardiovascular events. The waist circumference-to-BMI ratio (WtBR) is an anthropometric measure integrating waist circumference and BMI. We utilized multivariable Cox regression analysis, restricted cubic spline model, Kaplan-Meier plot, random forest analysis, and sensitivity analysis to assess the relationship of WtBR with all-cause mortality. Subsequently, Fine-Gray competing risk regression models were applied to precisely evaluate the probability of cardiovascular-specific death attributed to high WtBR. The results indicate that thea deceased group showed significantly higher WtBR and lower BMI compared with the alive groups (P < .05), while no significant difference was observed in waist circumference (P = .373). When analyzed as continuous, the risk of all-cause death elevated with increasing WtBR in the adjusted model with an HR of 2.42 (95% CI, 2.06-2.85). The restricted cubic spline illustrated an elevated risk of all-cause mortality as WtBR increased (J-shaped curve). Nevertheless, WtBR showed no significant association with cardiovascular-specific death and the prediction model exhibited a reliable performance in the testing set. This study supported that WtBR, an anthropometric measure, is independently associated with all-cause death in hypertensive patients. It's advisable to routinely assess waist circumference in hypertensive patients regardless of BMI, in order to more effectively manage the risk of obesity-related health.

Malnutrition significantly affected centenarian prognoses: A prospective study with 5-year follow-up

BACKGROUND

The world is currently facing a much-needed conundrum, and population aging has become an important worldwide problem. Appropriate nutritional intervention could prolong survival time and reduce mortality rate. However, scarce study has involved the effects of nutrition on survival time in centenarians and evaluated the malnutrition with prognostic nutritional index (PNI) in relation to healthy aging. This prospective study was designed to investigate the effects of malnutrition through PNI assessment on mortality rate and survival time with 5-year follow-up in Chinese centenarians.

METHODS

A household survey was conducted on the centenarians in 18 cities and counties of Hainan province, and malnutrition was evaluated by PNI as an effective tool in 423 centenarians followed up for 5-year.

RESULTS

Prevalence of malnutrition was 19.4%. Body mass index (BMI) was significantly lower and malnutrition was significantly more in the dead group than those in the survival group (all P < 0.05). Multivariate Cox regression analysis indicated that BMI [Hazard ratio (HR): 0.913; 95%CI: 0.854-0.977] negatively affected mortality rate, whereas malnutrition (HR: 2.630; 95%CI:1.474-4.695) positively affected mortality rate in centenarians (all P < 0.05). When BMI was <18.5 kg/m2, malnutrition (HR: 4.401; 95%CI: 1.948-9.943) also positively affected mortality rate (P < 0.05).

CONCLUSIONS

This prospective study with 5-year follow-up demonstrated that malnutrition had positive effect on mortality rate, especially when BMI was lower than 18.5 kg/m2, in Chinese centenarians. In order to reduce mortality rate and prolong survival time, it is essential to pay attention to malnutrition in elderly population.

Associations between obesity, self-reported weakness and their combinations with mortality in nursing home residents

OBJECTIVES

There are studies on associations between obesity and mortality in nursing home (NH) residents, but the presence of concomitant muscle weakness has not been examined. We considered that self-reported weakness might be a low muscle strength proxy marker. We aimed to examine associations of obesity alone, self-reported muscle weakness alone, and their combination with mortality in NH residents.

METHODS

This is a retrospective longitudinal follow-up study. We noted age, sex, nutritional status, functionality, number of chronic diseases, and regular medication. Obesity was assessed by the body fat-percentage method estimated by bioimpedance analysis. Weakness was identified by self-reported muscle weakness. Survival was evaluated with a univariate log-rank test and multivariate Cox regression analyses.

RESULTS

We included 214 participants. In a median follow-up time of 46 months, mortality occurred in 37.4%. In multivariate analysis adjusted by age, sex, undernutrition, number of chronic diseases, and regular medication, functional scores; 'non-weak non-obese' participants or 'weak alone' participants or 'weak+obese' participants had higher mortality risk when compared with the 'obesity alone' participants [hazard ratio (HR) = 2.6, 95% confidence interval (CI) = 1.2-5.5, p = 0.01; HR = 2.6, 95% CI = 1.2-5.9, p = 0.02; HR = 3.0, 95% CI = 1.2-7.7, p = 0.02].

CONCLUSION

This is the first report showing that obesity was associated with lower mortality risk if the weakness was not present in NH residents. However, obesity with concomitant weakness was associated with mortality risk similar to non-weak non-obese or weak alone participants. Our study suggests a simple consideration of weakness that can easily be integrated into everyday practice.

Assessment of Food Intake Assisted by Photography in Older People Living in a Nursing Home: Maintenance over Time and Performance for Diagnosis of Malnutrition

Malnutrition is related to poor outcomes. Food intake semi-quantitative assessment is helpful for malnutrition screening. Aims: to assess maintenance over one month of one-day semi-quantitative assessment of food intake (primary aim) and its performance in diagnosing malnutrition (secondary aim) in older people living in a nursing home. Food portions consumed at lunch and dinner were measured during 20 days by the Simple Evaluation of Food Intake (SEFI)^® assisted by photography (SEFI^®-AP) in 70 residents. Nutritional status was assessed in each patient during the first week of food intake monitoring according to Global Leadership Initiative on Malnutrition criteria. Food intake was decreased, i.e., SEFI^®-AP < 7, in 39% (n = 27/73) of patients. According to the methods, 36 to 48% (n = 25 to 33/73) of patients had malnutrition, and 6 to 37% (n = 4 to 25/73) sarcopenia. According to a generalized linear model on ranks with repeated measures, the SEFI^®-AP medians of lunch (p = 0.11) and means of lunch and dinner (p = 0.15) did not vary over time. Day 3 SEFI^®-AP anticipated decreased food intake from days 4 to 20, with a sensitivity of 78% (95% confidence interval (CI), 62-94), a specificity of 30% [95%CI, 17-44] and positive and negative predictive values of 41% [95%CI, 28-55] and 68% [95%CI, 48-89]. The performance of SEFI^®-AP for diagnosis of malnutrition using calf circumference <31 cm as a phenotypic criterion was correct: area under the curve = 0.71 [95%CI, 0.59-0.83]. SEFI^®-AP sensitivity was better if ≤9.5 than <7, and inversely for specificity. The food intake of older people living in nursing homes is stable over one month. One-day SEFI^®-AP correctly anticipates food intake during the following month and predicts diagnosis of malnutrition. Any decrease in food intake should lead to suspect malnutrition.

Weight Loss and Weight Gain: Multi-Level Determinants Associated with Resident 3-Month Weight Change in Long-Term Care

This study examined factors associated with weight change in 535 residents in 32 long term care homes where 3-month weight records were available. Trained researchers and standardized measures (e.g., nutrition status, food intake, home characteristics) were used to collect data; weight change was defined as ±2.5%. Just over 25% of the sample lost and 21% gained weight. Weight stability was compared to loss or gain. Weight loss was associated with being male, malnourished (MNA-SF or BMI <25), energy and protein intake and oral nutritional supplement use, while weight gain was associated with being female, and a physically (e.g., less noise) and socially supportive dining room. Weight stability was associated with better cognition. A high proportion of residents had a significant weight change in 3 months. Modifiable factors associated with weight stability or gain suggest focusing interventions that promote food intake and improve the mealtime environment.

Sarcopenic Dysphagia Is Associated With Mortality in Institutionalized Older Adults

OBJECTIVE

To estimate mortality associated with sarcopenic dysphagia.

DESIGN

A 3-year follow-up cohort.

SETTING AND PARTICIPANTS

Ninety-five nursing home residents were evaluated to determine the baseline presence or absence of oropharyngeal dysphagia and followed up for 3 years.

METHODS

The primary outcome was the risk of death. Dysphagia was assessed using a volume-viscosity swallow test. We used an algorithm to determine sarcopenic dysphagia based on grip strength, walking speed, calf circumference, and exclusion of neurologic or structural causes of dysphagia. We constructed 3 subgroups: without dysphagia, nonsarcopenic dysphagia, and sarcopenic dysphagia. Cox proportional regression analyses were used to predict the risk of death.

RESULTS

Thirty-five percent of participants had no dysphagia, 20% nonsarcopenic dysphagia, and 45% sarcopenic dysphagia. Sarcopenic dysphagia was independently associated with a higher risk of death [hazard ratio (HR) 2.44, 95% CI 1.02-5.80, P = .043] than without dysphagia. In addition, a higher Charlson Comorbidity Index score was associated with a higher risk of death (HR 1.33, 95% CI 1.01-1.75, P = .040).

CONCLUSIONS AND IMPLICATIONS

This study shows that sarcopenic dysphagia was associated with increased mortality among institutionalized older adults. These deaths could be potentially preventable.

Long-term body weight change assessed by non-contact load cells under the bed in older people with and without eating assistance: a preliminary study

Utilizing automatic daily body weight (BW) measurements may be helpful for assessing nutritional status and detecting underlying diseases particularly in older people who require nursing care. This preliminary study aimed to verify effectiveness of eating assistance for maintaining BW in older people using a contact-free load cells under the bed (Bed Sensor System: BSS). BW was measured every night for 3 months in eight nursing home older people with severe cognitive and physical dysfunctions. Body composition of the subject's trunk and each limb was measured using a segmented multi-frequency bioelectrical impedance analyzer (BIA). A monthly BW loss was estimated as a slope of linear regression of the daily BW plot. BSS successfully measured daily BW for the study period in all participants. The 4 residents with eating assistance gained slightly more weight, while the 4 residents without eating assistance lost weight. There was a significant difference between the two groups in the monthly BW change (- 0.79 ± 0.51 kg/month versus 0.20 ± 0.49 kg/month, P = 0.030). None of the BIA-derived parameters was associated with the monthly BW change. BSS revealed effectiveness of eating assistance to maintain BW in nursing home residents with severe cognitive and physical dysfunctions.

Mortality risks of body mass index and energy intake trajectories in institutionalized elderly people: a retrospective cohort study

Background

Many factors can identify the mortality risks of institutionalized elderly people; among all such factors, body mass index (BMI) and energy intake (EI) can be employed as independent predictors. The objective of this study was to elucidate about the mortality risks and the trajectory of two parameters obtained from continuously monitored data.

Methods

This retrospective cohort study targeted 218 elderly people who were admitted to a nursing home for at least 6 months between 2007 and 2020 and passed away at the nursing home. BMI and EI (kcal) per body weight (BW) were continuously measured until death.

Results

BMI continued to decrease for 5 years until death. The rate of change of BMI significantly increased for 3 years before death (P = 0.004). In contrast, the rate of change of EI per BW significantly increased after 1 year before death (P < 0.001); in addition, 2 months before death, this rate of change significantly exceeded that of BMI (P = 0.007). In the four risk groups that were examined, a BMI of <18.0 + EI per BW of <29.2 and a BMI of <17.3 + EI per BW of <28.3 were significantly correlated with a high risk of death (log-rank test: P < 0.001, P = 0.002, respectively). There was no significant difference in the hazard ratio based on the age at the time of admission; however, when EI per BW was <23.8, the risk of death was significantly higher [hazard ratio = 4.36; 95% confidence interval: 2.31–8.24].

Conclusions

Elderly people in the current study presented a tendency toward decreasing BMI starting 60 months prior to death even if EI per BW remained constant. In the 1 year before death, EI per BW rapidly decreased. When the rate of change of EI per BW exceeded the rate of decrease of BMI, it was considered to be the point of no return when death was imminent. Our study showed that identifying mortality risks from the relationship between the trajectories of the two parameters that were continuously measured for several months to years is possible.

Association between Weight Loss and Food Form in Older Individuals Residing in Long-Term Care Facilities: 1-Year Multicenter Longitudinal Study

Changing the food form for older adults requiring nursing care from a regular to dysphagia diet is thought to impact their nutritional status. We assessed the association between changes in food form and weight loss over 1 year in older adults. Older adults residing in long-term care facilities in Japan (n = 455) who participated in the baseline (2018) and follow-up (2019) surveys were divided into two groups (regular diet, n = 284; dysphagia diet, n = 171). The regular diet group was further divided into the weight loss (n = 80; weight loss ≥5% over 1 year) and weight maintenance (n = 204; weight loss <5%) groups. After 1 year, the Barthel Index significantly decreased, and the proportion of participants who switched from a regular diet to a dysphagia diet significantly increased in the weight loss group than in the weight maintenance group. Multivariate logistic regression analysis found that Barthel index variation (odds ratio (OR): 0.97, 95% confidence interval (CI): 0.94‒0.99), change from a regular diet to a dysphagia diet (OR: 4.41, 95% CI: 1.87‒10.41), and body weight at baseline (OR = 1.06, 95% CI: 1.01‒1.11) were significantly associated with weight loss. Our results suggest that maintaining the food form inhibits weight loss and improves health outcomes in older adults.

Determination of the Personal Nutritional Status of Elderly Populations Based on Basic Foodomics Elements

Nutritional status is a series of related parameters collected using different available methods. In order to determine the nutritional status of elderly populations and ensure nutritional support based on an individual approach, the implementation of the increasingly used foodomics approach is available; this approach plays a key role in personalized diets and in the optimization of diets for a population group, such as an elderly population. The Mini Nutritional Assessment (MNA) method and the Nottingham Screening Tool (NST) form were used on 50 users in a home for the elderly in northwest Croatia. A loss of body mass (BM) was statistically significantly higher for those who had the following: decreased food intake in the last week and users who had complete and partial feeding autonomy. Additionally, the obtained data on drug intake, fluid, individual nutrients, and physical activity are based on an individual approach. The available documentation provides insight into nutritional values and food preparation in an attempt to satisfy a holistic approach in the evaluation of exposure while trying to achieve as many elements of foodomics as possible.

The WeanCare nutritional intervention in institutionalized dysphagic older people and its impact on nursing workload and costs: A quasi-experimental study

AIM

The aim of this study is to explore how a nutritional intervention that improves the biochemical and functional profile of dysphagic older people impacts on nursing workload and costs for nursing homes.

BACKGROUND

Dysphagic institutionalized older people particularly at risk of malnutrition require more intensive support from nursing staff and higher costs for nursing homes.

METHOD

This is an open pre-post longitudinal multicentre quasi-experimental study without a control group.

RESULTS

There is a significant reduction in the number of enemas (from 3.51 to 1.11 enemas), with an average nursing workload reduction from 52 to 16 min per patient every month. Each nurse also spent 20 h less per patient every month spoon-feeding. This resulted in nursing staff cost savings.

CONCLUSIONS

The nutritional intervention led to a significantly better quality of life for the patients manifested through increased independence and social engagement. This reduced workload for nursing staff and costs for nursing home administrators.

IMPLICATIONS FOR NURSING MANAGEMENT

Sensitive, targeted nutritional interventions have the potential to improve nursing home residents' quality of life and enable a more efficient use of resources. This study revealed reduced workload and cost savings due to less time spent administering enemas and spoon-feeding, in addition to reduced malnutritional consequences.

Predictors of incident malnutrition-a nutritionDay analysis in 11,923 nursing home residents

Background/Objectives

Malnutrition (MN) in nursing home (NH) residents is associated with poor outcome. In order to identify those with a high risk of incident MN, the knowledge of predictors is crucial. Therefore, we investigated predictors of incident MN in older NH-residents.

Subjects/Methods

NH-residents participating in the nutritionDay-project (nD) between 2007 and 2018, aged ≥65 years, with complete data on nutritional status at nD and after 6 months and without MN at nD. The association of 17 variables (general characteristics (n = 3), function (n = 4), nutrition (n = 1), diseases (n = 5) and medication (n = 4)) with incident MN (weight loss ≥ 10% between nD and follow-up (FU) or BMI (kg/m²) < 20 at FU) was analyzed in univariate generalized estimated equation (GEE) models. Significant (p < 0.1) variables were selected for multivariate GEE-analyses. Effect estimates are presented as odds ratios and their respective 99.5%-confidence intervals.

Results

Of 11,923 non-malnourished residents, 10.5% developed MN at FU. No intake at lunch (OR 2.79 [1.56–4.98]), a quarter (2.15 [1.56–2.97]) or half of the meal eaten (1.72 [1.40–2.11]) (vs. three-quarter to complete intake), the lowest BMI-quartile (20.0–23.0) (1.86 [1.44–2.40]) (vs. highest (≥29.1)), being between the ages of 85 and 94 years (1.46 [1.05; 2.03]) (vs. the youngest age-group 65–74 years)), severe cognitive impairment (1.38 [1.04; 1.84]) (vs. none) and being immobile (1.28 [1.00–1.62]) (vs. mobile) predicted incident MN in the final model.

Conclusion

10.5% of non-malnourished NH-residents develop MN within 6 months. Attention should be paid to high-risk groups, namely residents with poor meal intake, low BMI, severe cognitive impairment, immobility, and older age.

Quotient of Waist Circumference and Body Mass Index: A Valuable Indicator for the High-Risk Phenotype of Obesity

OBJECTIVE

Measuring the body mass index (BMI) or waist circumference (WC) alone is insufficient for assessing possible health risks due to obesity. This study aimed to investigate whether the quotient of WC and BMI can be used as a proxy of the high-risk phenotype of obesity.

METHODS

Data for analysis were derived from the National Health and Nutrition Examination Survey (NHANES 1999-2014). The Waist-BMI Ratio was defined as WC divided by BMI. The associations between Waist-BMI Ratio and mortality were estimated using Cox regression models. Restricted cubic spline and two-piecewise linear regression models were used to identify non-linear relationships. The discriminative abilities of different anthropometric measures were compared using receiver operating characteristic curves (ROC).

RESULTS

This study is based on data from 35557 adults (51.1% female, mean age 44.9 years). During an average follow-up of 101.8 months, 3680 participants died, including 807 of cardiovascular causes. In fully adjusted models, Waist-BMI Ratio was independently associated with overall (hazard ratio [HR], 1.78; 95% confidence interval [CI], 1.48-2.13) and cardiovascular (HR, 1.77; 95% CI, 1.25-2.52) mortality. Spline analyses revealed that dose-response relationships existed between Waist-BMI Ratio and death. The mortality risk rises dramatically above the cut-off point of the Waist-BMI Ratio (HR, 3.22; 95% CI, 2.43-4.26 for overall mortality and HR, 3.07; 95% CI, 1.71-5.52 for cardiovascular mortality). ROC curve analysis suggested that Waist-BMI Ratio was a better discriminator of mortality (AUC 0.637 for overall and 0.639 for cardiovascular mortality) than BMI, WC, and waist-to-height ratio (Delong's test all P <0.001).

CONCLUSIONS

Waist-BMI Ratio was independently associated with overall and cardiovascular mortality in a J-shaped pattern, offering an immense potential risk marker for obesity in the clinical setting.

Hungry for more: Low resident social engagement is indirectly associated with poor energy intake and mealtime experience in long-term care homes

Mealtimes in long-term care (LTC) homes provide social engagement and nutritional intake to residents. Psychosocial challenges may detract from the mealtime experience, resulting in low food intake and increased risk of malnutrition. This study explores the independent effects of psychosocial factors on energy intake among LTC residents. Secondary data (Making the Most of Mealtimes [M3]) from residents in 32 Canadian LTC homes were analyzed. Data included 3-day weighed food intake, mealtime care actions taken by staff, loss of appetite, eating challenges, and other resident characteristics. Psychosocial factors (i.e., social engagement, depression, and aggressive behaviours) were measured using standardized scales. The independent effects of psychosocial factors on energy intake were tested using bivariate and linear regression analyses adjusted for loss of appetite, eating challenges, and demographic characteristics. The final sample included 604 residents (mean age = 86.8 ± 7.8 years; 31.8% male). Of the three psychosocial factors, only social engagement was associated with energy intake. Low social engagement was associated with cognitive and functional challenges, malnutrition risk, more task-focused mealtime actions by staff, and lower energy intake. Simple regression analysis revealed that individuals with low social engagement ate 59.6 kcal less per day (95% CI = -111.2, -8.0). This significant association remained when adjusting for loss of appetite, but was no longer significant when adjusting for eating challenges. Low social engagement occurs concurrently with physical and functional challenges among LTC residents, affecting both the nutritional and social aspects of mealtimes. Emphasis on socializing during mealtimes, especially for those with eating challenges (e.g., requiring assistance), may contribute to improved resident appetite and quality of life.

Double burden of malnutrition amongst patients with first-episode schizophrenia in a psychiatric hospital: A 1-year follow-up study

BACKGROUND

Despite the burgeoning data on the double burden of malnutrition (DBM) in sub-Saharan Africa, longitudinal studies to examine malnutrition amongst first-episode schizophrenia are uncommon in the modern literature.

AIM

To determine the extent of nutritional variations amongst persons with schizophrenia at intervals of 1-year treatment follow-up.

SETTING

This study was conducted at the Federal Neuropsychiatric Hospital, Enugu, Nigeria.

METHODS

Consecutive incident cases that fulfilled the criteria for schizophrenia were recruited into the study. After a baseline assessment, 206 incident cases of schizophrenia were followed up at 4th, 8th, 12th weeks, 6 months and 1 year for indicators of nutritional outcome. The body mass index (BMI) was used to measure the nutritional status amongst the study participants. Changes in the BMI across intervals of follow-up were examined using repeated measures analysis of variance, whereas the socio-demographic and clinical variables were evaluated as predictors of outcome using multiple regression analysis.

RESULTS

After 1 year of treatment with antipsychotics, the prevalence of underweight decreased from 19.9% (95% CI, 19.8% - 20.0%) at baseline to 16.0% (95% CI, 15.9% - 16.1%) at 1 year, but the prevalence of overweight/obesity increased from 29.1% (95% CI, 29.0% - 29.2%) at baseline to 43.2% (95% CI, 43.0% - 43.3%) at 1 year of follow-up. The predictors of BMI at 1 year were antipsychotic medication (32.7% variance), duration of vagrancy (24.0%) and age at onset (20.0%).

CONCLUSION

The finding of coexistence of undernutrition and overnutrition across the intervals of treatment follow-up underscores the need for comprehensive interventions to address both extremes of malnutrition amongst patients with schizophrenia.

Emergency department and hospital admissions among people with dementia living at home or in nursing homes: results of the European RightTimePlaceCare project on their frequency, associated factors and costs

Background

Evidence is lacking on the differences between hospitalisation of people with dementia living in nursing homes and those living in the community. The objectives of this study were: 1) to describe the frequency of hospital admission among people with dementia in eight European countries living in nursing homes or in the community, 2) to examine the factors associated with hospitalisation in each setting, and 3) to evaluate the costs associated with it.

Methods

The present study is a secondary data analysis of the RightTimePlaceCare European project. A cross-sectional survey was conducted with data collected from people with dementia living at home or who had been admitted to a nursing home in the last 3 months, as well as from their caregivers. Data on hospital admissions at 3 months, cognitive and functional status, neuropsychiatric symptoms, comorbidity, polypharmacy, caregiver burden, nutritional status, and falls were assessed using validated instruments. Multivariate regression models were used to investigate the factors associated with hospital admission for each setting. Costs were estimated by multiplying quantities of resources used with the unit cost of each resource and inflated to the year 2019.

Results

The study sample comprised 1700 people with dementia living in the community and nursing homes. Within 3 months, 13.8 and 18.5% of people living in nursing homes and home care, respectively, experienced ≥1 hospital admission. In the nursing home setting, only polypharmacy was associated with a higher chance of hospital admission, while in the home care setting, unintentional weight loss, polypharmacy, falls, and more severe caregiver burden were associated with hospital admission. Overall, the estimated average costs per person with dementia/year among participants living in a nursing home were lower than those receiving home care.

Conclusion

Admission to hospital is frequent among people with dementia, especially among those living in the community, and seems to impose a remarkable economic burden. The identification and establishment of an individualised care plan for those people with dementia with polypharmacy in nursing homes, and those with involuntary weight loss, accidental falls, polypharmacy and higher caregiver burden in the home care setting, might help preventing unnecessary hospital admissions.

Impact of morbidity on care need increase and mortality in nursing homes: a retrospective longitudinal study using administrative claims data

Background

A growing number of older people are care dependent and live in nursing homes, which accounts for the majority of long-term-care spending. Specific medical conditions and resident characteristics may serve as risk factors predicting negative health outcomes. We investigated the association between the risk of increasing care need and chronic medical conditions among nursing home residents, allowing for the competing risk of mortality.

Methods

In this retrospective longitudinal study based on health insurance claims data, we investigated 20,485 older adults (≥65 years) admitted to German nursing homes between April 2007 and March 2014 with care need level 1 or 2 (according to the three level classification of the German long-term care insurance). This classification is based on required daily time needed for assistance. The outcome was care level change. Medical conditions were determined according to 31 Charlson and Elixhauser conditions. Competing risks analyses were applied to identify chronic medical conditions associated with risk of care level change and mortality.

Results

The probability for care level change and mortality acted in opposite directions. Dementia was associated with increased probability of care level change compared to other conditions. Patients who had cancer, myocardial infarction, congestive heart failure, cardiac arrhythmias, renal failure, chronic pulmonary disease, weight loss, or recent hospitalization were more likely to die, as well as residents with paralysis and obesity when admitted with care level 2.

Conclusion

This paper identified risk groups of nursing home residents which are particularly prone to increasing care need or mortality. This enables focusing on these risk group to offer prevention or special treatment. Moreover, residents seemed to follow specific trajectories depending on their medical conditions. Some were more prone to increased care need while others had a high risk of mortality instead. Several conditions were neither related to increased care need nor mortality, e.g., valvular, cerebrovascular or liver disease, peripheral vascular disorder, blood loss anemia, depression, drug abuse and psychosis. Knowledge of functional status trajectories of residents over time after nursing home admission can help decision-makers when planning and preparing future care provision strategies (e.g., planning of staffing, physical equipment and financial resources).

Energy Gap between Doubly Labeled Water-Based Energy Expenditure and Calculated Energy Intake from Recipes and Plate Waste, and Subsequent Weight Changes in Elderly Residents in Japanese Long-Term Care Facilities: CLEVER Study

Unintentional weight loss is a major frailty component; thus, assessing energy imbalance is essential for institutionalized elderly residents. This study examined prediction errors of the observed energy intake (OEI) against the actual energy intake obtained from the doubly labeled water (DLW) method and clarified the relationship between the energy gap obtained by subtracting total energy expenditure (TEE) from OEI and subsequent weight changes in elderly residents in long-term care facilities. Overall, 46 participants were recruited in Japan. TEE was measured using the DLW method, and OEI was calculated from recipes and plate waste simultaneously over a 14–15-day period at baseline. The total energy intake (TEI_DLW) was determined on the basis of DLW and weight changes during the DLW period. The weight was longitudinally tracked monthly for 12 months in the 28 residents who still lived at the facilities. OEI was higher than TEI_DLW by a mean of 232 kcal/day (15.3%) among 46 residents at baseline. The longitudinal data of 28 residents showed that the energy gap tended to be correlated with the slope of weight change (ρ = 0.337, p = 0.080) and the median value was significantly lower in the weight loss group (152 kcal/day) than in the weight gain group (350 kcal/day) (p < 0.05). In conclusion, weight loss could occur at Japanese long-term care facilities even if the difference obtained by subtracting TEE from OEI was positive because OEI was overestimated by more than 200 kcal/day.

Body mass index, waist circumference, and mortality risks over 27 years of follow-up in old age

PURPOSE

This study investigates the predictive effects of body mass index (BMI) and waist circumference (WC) for all-cause mortality in old age over 27 years of follow-up.

METHODS

Participants were from the Berlin Aging Study (n = 444, M ± SD = 84.55 ± 8.38 years). Reported significance values for hazard ratios were adjusted for age, sex, socioeconomic status, smokers, depressive illness, functional status, cholesterol, and objectively assessed physical diseases.

RESULTS

BMI emerged as a significant predictor of all-cause mortality after adjustment. WC was not a significant predictor of mortality either within the unadjusted model or when fully adjusted, including BMI. After the introduction of WC alongside all covariates, the effect for BMI remained significant. A significant quadratic effect for BMI and mortality within the fully adjusted model also emerged.

CONCLUSIONS

Our results suggest that lower BMI in the oldest old is associated with increased mortality hazards, and risks were particularly elevated for people who are underweight. This study found no evidence that higher BMI in old age is associated with increased mortality hazards relative to normal weight ranges.

Association of oral health with body weight: a prospective study in community-dwelling older adults

BACKGROUND

To prevent involuntary weight loss in older people, the knowledge about factors affecting body weight (BW) is essential. Therefore, we aimed to investigate the longitudinal associations of multiple oral health aspects with BW in community-dwelling older adults.

METHODS

This analysis is based on prospective data with a 10-year follow-up of 657 Dutch community-dwelling older adults (age 66.4 ± 5.8 years, 54% female) from the Longitudinal Aging Study Amsterdam. Participants' characteristics, BW, and 12 oral health variables (teeth, dentures, nine oral problems, self-rated oral health) were assessed in 2005/07 and 2015/16. The association between oral health and BW was analyzed by mixed models and adjusted for demographic, socio-economic, smoking, health, and functional aspects considering data of both assessments.

RESULTS

Mean BW was 79.1 ± 13.3 kg at baseline (B) and 77.6 ± 13.8 kg at follow-up (FU). At baseline, 29.6% of the participants reported being edentulous (FU:34.4%) and 55.8% to wear dentures (FU:62.3%). Dental pain while chewing was the oral problem with the lowest (B:5.2%, FU:6.6%) and xerostomia with the highest prevalence at both examinations (B:24.3%, FU:30.0%). Most participants rated their oral status as healthy (B:65.2%, FU:66.9%). Neither edentulism and denture use nor oral problems showed a longitudinal association with BW. In contrast, self-rated oral health was associated with BW (b = 0.724, SE = 0.296, p = 0.015) after adjusting for multiple confounders.

CONCLUSIONS

In community-dwelling older adults self-rated oral health may indicate changes in body weight in the long term. Therefore, this simple measure could serve to identify a risk for weight loss and to initiate oral interventions in clinical practice.

Home Enteral Nutrition in Singapore's Long-Term Care Homes-Incidence, Prevalence, Cost, and Staffing

Introduction: Data on home enteral nutrition (HEN) in long-term care facilities (LTCF) in Singapore is scarce. This study aims to determine the prevalence and incidence of chewing/swallowing impairment and HEN, and the manpower and costs related. Methods: A validated cross-sectional survey was sent to all 69 LTCFs in Singapore in May 2019. Local costs (S$) for manpower and feeds were used to tabulate the cost of HEN. Results: Nine LTCFs (13.0%) responded, with a combined 1879 beds and 240 residents on HEN. An incidence rate (IR) of 15.7 per 1000 people-years (PY) and a point prevalence (PP) of 136.6 per 1000 residents were determined for HEN, and an IR of 433.0 per 1000 PY, with PP of 385.6 per 1000 residents for chewing/swallowing impairment. Only 2.5% of residents had a percutaneous endoscopic gastrostomy (PEG). The mean length of residence in LTCF was 45.9 ± 12.3 months. More than half of the residents received nasogastric tube feeding (NGT) for ≥36 months. Median monthly HEN cost per resident was S$799.47 (interquartile range (IQR): 692.11, 940.30). Nursing costs for feeding contributed to 63% of total HEN costs. Conclusions: The high usage and length of time on NGT feeding warrants exploration and education of PEG usage. A national HEN database may improve the care of LTCF residents.

Is low body mass index a risk factor for semen quality? A PRISMA-compliant meta-analysis

BACKGROUND

Male infertility has become a worldwide public health problem. However, the effect of low body mass index (BMI) is still controversial.

METHODS

Relevant articles in Pubmed, Embase, Web of science, and Wanfang database published until September 2017 were searched without language restriction. We performed a meta-analysis about low BMI and semen parameters containing total sperm count, concentration, semen volume, and sperm motility (overall and progressive), including 709 men with low BMI and 14,622 men with normal BMI.

RESULTS

Thirteen studies were included in this meta-analysis and a total of 15,331 individuals were accumulated. We pooled data from these articles and found standardized weighted mean differences in semen parameters (total sperm count and semen volume) showed significant difference between low BMI and normal BMI.

CONCLUSIONS

This systematic review with meta-analysis has confirmed that there was a relationship between low BMI and semen quality, which suggesting low BMI may be a harmful factor of male infertility. Yet lacking of the raw data may influence the accuracy of the results. Further researches are needed to identify the role of underweight in male sterility.

Nutritional status and factors associated with non-institutionalized people over 75 years of age

OBJECTIVE

to determine the factors related to the risk of malnutrition in a non-institutionalized population over 75 years of age.

METHOD

a cross-sectional study was conducted using a questionnaire in a sample of 326 individuals over 75 years of age in Castellón (Spain), during 2015, and selected through intentional sampling.

RESULTS

Malnutrition prevalence was 2.8%. 26.9% of the individuals were at risk of malnutrition, whereas women presented a higher rate (31.5%). Women with a good overall health status showed a lower rate than men, 55% and 69%, respectively. Individuals that showed a lower risk of malnutrition are those with a positive perception than those who have a good overall health. Frail elderly people showed a higher risk of malnutrition (57.5%) compared to non-frail subjects (20.2%) p< 0.001.

CONCLUSION

Frail women, self-assessed health, overall health, and use of health care services (nursing consultation) were related to a higher risk of malnutrition.

[Anemia in the aged]

Anemia in the aged is still often an underestimated clinical problem; however, in recent years increasing research on this topic has permitted deeper insights, allowing a differentiated approach to anemia in the aged. Meanwhile, multicausality and a negative impact on functional outcome have become characteristics of anemia in older people. This has led to a scientific discussion on the question of accepting anemia as a geriatric syndrome. The present article gives a concise overview of the current state of research on this clinically relevant subject.

The Impact of Dysphagia on Mortality of Nursing Home Residents: Results From the nutritionDay Project

OBJECTIVES

Dysphagia is a frequent finding in nursing home residents. The aim of this study is to evaluate the association of dysphagia and mortality in nursing home residents and identify further risk factors for mortality in residents with dysphagia.

DESIGN

One-day, annually repeated cross-sectional study, evaluating the nutritional situation of nursing home residents with 6-month mortality as outcome.

SETTING

191 nursing homes from 14 countries in Europe and the United States participating in the nutritionDay study between 2007 and 2012.

PARTICIPANTS

Data of all nursing home residents in the nutritionDay study aged 65 years or older with available information about dysphagia and outcome were analyzed.

MEASUREMENTS

Residents' characteristics and mortality rate were calculated by group comparison, and mortality risk was calculated by multivariate regression analysis with adjustment for potential confounding factors.

RESULTS

10,185 residents (78% female) with a mean age of 85 ± 8.1 years were included in the analysis. Dysphagia was reported in 15.4% of residents. The 6-month mortality of residents with dysphagia was significantly higher than of those without dysphagia (24.7% vs 11.9%; P < .001). The multivariate regression analysis revealed dysphagia [odds ratio (OR) 1.44, 95% confidence interval (CI) 1.24-1.68, P < .001] along with body mass index <20 (OR 1.78, 95% CI 1.55-2.03, P < .001) and weight loss >5 kg (OR 1.61, 95% CI 1.37-1.88, P < .001) as independent and significant risk factors for mortality. Because of significant interaction, a disproportionately high mortality of 38.9% was found in residents with dysphagia accompanied by previous weight loss >5 kg (OR for interaction 1.44; 95% CI 1.03-2.01; P = .032). Tube feeding was reported in 14.6% of residents with dysphagia. The mortality rate of dysphagic residents receiving tube feeding vs those who were not was not significantly different (21.4% vs 25.3%; P = .244).

CONCLUSION

In this nutritionDay study, dysphagia was identified as an independent risk factor for mortality in nursing home residents. Residents with dysphagia accompanied by weight loss are at a particularly high risk of mortality and should therefore receive special attention.

Underweight and hypoalbuminemia as risk indicators for mortality among psychiatric patients with medical comorbidities

AIM

Medical comorbidities are a major cause of death among patients with mental illness. The purpose of this study was to clarify the risk factors for mortality among psychiatric patients with medical comorbidities.

METHODS

We retrospectively reviewed the clinical files of patients transferred to Tokyo Metropolitan Matsuzawa Hospital from a psychiatric hospital to treat medical comorbidities during the 3-year period from January 2014 to December 2016. We analyzed the clinical differences between the expired and alive patients.

RESULTS

Of the 287 patients included, 29 (10.1%) had expired at the time of hospital discharge, while 258 (89.9%) were living. A multivariable analysis to determine the prognostic factors related to mortality from medical comorbidities showed that body mass index <18.5 had the highest odds ratio among the predictive factors (5.1; 95% confidence interval, 1.5-17.1; P < 0.05), followed by a serum albumin level < 3.0 mg/dL (3.0; 95% confidence interval, 1.1-8.1; P < 0.05).

CONCLUSION

We found that underweight and hypoalbuminemia were risk factors for mortality among psychiatric patients with medical comorbidities. Physicians at psychiatric hospitals should consider transferring patients with medical comorbidities to a general medical hospital in the presence of underweight and/or hypoalbuminemia.

[Neurogenic dysphagia]

Approximately half of neurological and geriatric inpatients suffer from oropharyngeal dysphagia. This often leads to pneumonia, malnutrition and dehydration; however, the underlying dysphagia is frequently not diagnosed and treated. This is particularly the case for patients with so-called silent aspiration. Knowledge on the physiology of swallowing, including the central nervous system control of swallowing and the therapeutic options have achieved considerable progress in recent years. In particular, the increasing implementation of flexible endoscopic evaluation of swallowing (FEES) has significantly contributed to this knowledge. It provides the ability to identify the individual pattern of oropharyngeal dysphagia leading to a suitable selection of therapeutic and compensatory strategies for individual patients. The various therapeutic options range from modification of the consistency of the diet, over diverse logopedic strategies and stimulation techniques up to interventional procedures.

Making the Most of Mealtimes (M3): protocol of a multi-centre cross-sectional study of food intake and its determinants in older adults living in long term care homes

BACKGROUND

Older adults living in long term care (LTC) homes are nutritionally vulnerable, often consuming insufficient energy, macro- and micronutrients to sustain their health and function. Multiple factors are proposed to influence food intake, yet our understanding of these diverse factors and their interactions are limited. The purpose of this paper is to fully describe the protocol used to examine determinants of food and fluid intake among older adults participating in the Making the Most of Mealtimes (M3) study.

METHODS

A conceptual framework that considers multi-level influences on mealtime experience, meal quality and meal access was used to design this multi-site cross-sectional study. Data were collected from 639 participants residing in 32 LTC homes in four Canadian provinces by trained researchers. Food intake was assessed with three-days of weighed food intake (main plate items), as well as estimations of side dishes, beverages and snacks and compared to the Dietary Reference Intake. Resident-level measures included: nutritional status, nutritional risk; disease conditions, medication, and diet prescriptions; oral health exam, signs of swallowing difficulty and olfactory ability; observed eating behaviours, type and number of staff assisting with eating; and food and foodservice satisfaction. Function, cognition, depression and pain were assessed using interRAI LTCF with selected items completed by researchers with care staff. Care staff completed a standardized person-directed care questionnaire. Researchers assessed dining rooms for physical and psychosocial aspects that could influence food intake. Management from each site completed a questionnaire that described the home, menu development, food production, out-sourcing of food, staffing levels, and staff training. Hierarchical regression models, accounting for clustering within province, home and dining room will be used to determine factors independently associated with energy and protein intake, as proxies for intake. Proportions of residents at risk of inadequate diets will also be determined.

DISCUSSION

This rigorous and comprehensive data collection in a large and diverse sample will provide, for the first time, the opportunity to consider important modifiable factors associated with poor food intake of residents in LTC. Identification of factors that are independently associated with food intake will help to develop effective interventions that support food intake.

nutritionDay in Nursing Homes-The Association of Nutritional Intake and Nutritional Interventions With 6-Month Mortality in Malnourished Residents

OBJECTIVES

Malnutrition in older persons is associated with an increased risk of mortality. Useful strategies to counteract malnutrition are nutritional interventions, such as fortified diets, oral nutritional supplements (ONS), tube feeding, and parenteral nutrition. Presently, it is not known if these strategies can reduce mortality risk of nursing home (NH) residents who are malnourished or at risk of malnutrition. Thus, the aim of this study was to investigate if nutritional intake and interventions are associated with mortality in this specific population.

DESIGN

One-day cross-sectional study with outcome evaluation after 6 months, repeated in yearly intervals since 2007.

SETTING

A total of 507 NH units from 15 countries.

PARTICIPANTS

NH residents participating in the nutritionDay between 2007 and 2014, aged 65 years or older with a poor nutritional status (body mass index <20 kg/m² or weight loss >5 kg in the last year or at risk of malnutrition or malnourished according to NH staff).

MEASUREMENTS

Data on resident and unit level were collected on nutritionDay and mortality status was assessed 6 months later. Residents' nutrition (intake at lunch on nutritionDay) and nutritional interventions (diet, use of ONS, supplementary tube feeding, supplementary parenteral nutrition) were of interest as influencing factors of 6-month mortality, adjusted for 23 potential confounders (residents' nutritional status, general residents' characteristics, and unit characteristics). Univariate generalized estimating equations were performed for all variables and significant predictors (P < .01) included in a multivariate analysis.

RESULTS

Six-month mortality rate of the included 4857 NH residents was 20.3%. Univariate analysis identified residents' diet, use of ONS, intake at lunch, and 14 confounders as predictors of mortality. Intake at lunch and 7 confounders remained in the multivariate model [area under the receiver operating curve = 0.687; 95% confidence interval (CI) 0.669-0.706; P < .001]. The less residents ate for lunch, the higher was the risk of mortality, with the highest odds ratio (OR) for residents who ate nothing (OR 3.38; 95% CI 2.58-4.42). Mortality risk was OR 2.36; 95% CI 1.91-2.92, and OR 1.64; 95% CI 1.29-2.07 times higher for immobile and partially mobile compared with mobile residents. Cancer, dysphagia, weight loss >5 kg in the last year, body mass index <20 kg/m², residents' country region, and increasing age were also associated with a higher mortality risk.

CONCLUSIONS

Poor intake at lunch on nutritionDay was a strong predictor of mortality, whereas the use of nutritional interventions was not associated with 6-month mortality in NH residents who are malnourished or at risk of malnutrition. The reasons for these findings need to be clarified.

Who receives oral nutritional supplements in nursing homes? Results from the nutritionDay project

BACKGROUND & AIMS

Oral nutritional supplements (ONS) can be helpful for nursing home (NH) residents to prevent or treat malnutrition. Presently little is known about the use of ONS in NHs and the factors associated with its use. Thus, the aim of this analysis was to describe the use of ONS in NHs participating in the nutritionDay project and to determine characteristics of NH residents receiving ONS.

METHODS

Data from nutritionDay (nD), a cross-sectional multicenter study with standardized questionnaires on resident and NH level were analyzed. NH residents participating between 2007 and 2014 aged 65 years or older were included. Unit characteristics (2 variables), general residents' characteristics (18), residents' nutritional status (3) and residents' nutrition (4) were of interest as potential predictors of the use of ONS (no vs yes). Univariate binary logistic regression (LR) analyses were performed for all variables, and significant predictors (p < 0.05) subsequently included in a multivariate analysis (backwards LR).

RESULTS

13.9% of 23,689 NH residents received ONS. Univariate analysis identified all variables as predictors. After multivariate analysis 19 variables remained in the model (Nagelkerke's R² = 0.319). Odds ratios (OR [95% Confidence Interval]) of receiving ONS were highest in residents receiving supplementary parenteral nutrition (29.05 [14.85-56.81]; however only 1.1% of all participants) and fortified diet (11.91 [8.52-16.64]; 5.7%). The odds ratio of receiving ONS was 3.26 ([2.86-3.71]; 18.3%) for residents being classified as at risk of malnutrition and 4.56 ([3.86-5.40]; 10.0%) for malnourished residents according to NH staff. Low BMI and weight loss in the last year increased the odds of receiving ONS by 2.34 ([1.93-2.84]; 16.0%) and 1.38 ([1.23-1.54]; 32.8%), respectively. Furthermore, increasing age, cognitive and functional impairment, low food intake on nD, neurological disease and cancer were associated with an increased likelihood of the use of ONS. In NH units with a nutritional expert (67.1%) and units performing a nutritional assessment at least once a month (71.6%), the odds of receiving ONS were also significantly increased (1.89 [1.71-2.10] and 1.17 [1.06-1.29]).

CONCLUSION

In NHs who participated in the nutritionDay, ONS are used for residents with poor nutritional and functional status and often in combination with other nutritional interventions. Future studies need to clarify the role of NH staff in the prescription and distribution of ONS and focus on the reasons for and adequacy of the use of ONS in NHs.

NutriLive: An Integrated Nutritional Approach as a Sustainable Tool to Prevent Malnutrition in Older People and Promote Active and Healthy Ageing—The EIP-AHA Nutrition Action Group

The present document describes a nutritional approach that is nested in the European Innovation Partnership for Active and Healthy Aging (EIP-AHA) and aims to provide the first common European program translating an integrated approach to nutritional frailty in terms of a multidimensional and transnational methodology. The document has been developed by the A3 Nutrition Action Area of the EIP-AHA and aims at providing a stepwise approach to malnutrition in older citizens, identifying adequate interventions based on a unified assessment and ICT-supported solutions. “NutriLive” is an integrated nutritional approach, represented by a structured Screening-Assessment-Monitoring-Action-Pyramid-Model (SAM-AP). Its core concept is the stratification of the nutritional needs, considered by the working group as the key for targeted, effective, and sustainable interventions. “NutriLive” tries to close gaps in epidemiological data within an aging population, creating a unified language to deal with the topic of nutrition and malnutrition in Europe. By assembling all the validated screening, assessment, and monitoring tools on malnutrition in a first pyramid, which is interrelated to a second intervention pyramid, the A3 Nutrition WG identifies a common, integrated vision on the nutritional approach to frailty, which applies to the various health care settings.

High prevalence of underweight and undernutrition in Japanese inpatients with schizophrenia: a nationwide survey

OBJECTIVES

To clarify the prevalence of underweight and overweight/obesity, and laboratory data for nutritional status in Japanese outpatients and inpatients with schizophrenia.

DESIGN

Cross-sectional study.

SETTING

A questionnaire conducted in inpatient and outpatient facilities in Japan.

PARTICIPANTS

The population of adult patients with schizophrenia in Japan (N=23,116).

MAIN OUTCOME MEASURES

The prevalence of underweight and undernutrition in Japanese inpatients and outpatients with schizophrenia.

RESULTS

We conducted a large-scale investigation of the prevalence of underweight and undernutrition in 520 outpatient facilities and 247 inpatient facilities belonging to the Japan Psychiatric Hospitals Association between January 2012 and July 2013. There were 7655 outpatients and 15,461 inpatients with schizophrenia. There was a significant difference in the distribution of three body mass index levels between outpatients and inpatients (p<0.001). The proportion of underweight inpatients with schizophrenia was significantly higher than that among outpatients (p<0.001). Age-specific analysis revealed that the proportion of underweight individuals aged ≥ 40 years was higher in inpatients than in outpatients and in the general Japanese population. The proportion of individuals with hypocholesterolaemia was significantly higher in inpatients with schizophrenia than in outpatients (p<0.001). There was a significant difference in the severity of underweight between outpatients and inpatients with schizophrenia; the proportion of severe underweight in inpatients was twofold higher than in outpatients.

CONCLUSIONS

The prevalence of underweight and undernutrition in Japanese inpatients with schizophrenia was higher than in outpatients and the general population. Therefore, the physical risk of inpatients should be carefully considered in clinical practice.
