Assessment of the energy expenditure of Belgian nursing home residents using indirect calorimetry

A systematic review and meta-analysis of the dietary fiber menu provision and consumption for older adults living in residential care facilities

BACKGROUND

Older adults living in residential care facilities are commonly given laxatives to treat constipation; however, these may not always provide full relief, and side effects include diarrhea. Dietary fiber effectively prevents constipation, and international guidelines recommend 25 g/d for optimal laxation. Older adults in residential care rely on the facility menu to provide their nutritional requirements, including adequate dietary fiber. Little is known about how much dietary fiber is provided and consumed.

OBJECTIVES

We aimed to determine the provision and consumption of dietary fiber for older adults living in residential care facilities.

METHODS

We systematically searched available literature for studies reporting the analysis of residential care menus and meals consumed by residents aged over 65 y. A meta-analysis was performed on the studies that provided the mean amount of dietary fiber provided and consumed by residents. A random effect model was applied due to the heterogeneity of study methodologies.

RESULTS

The literature search yielded 4406 publications, but only 28 studies were eligible for our meta-analysis. The study sample comprised 4817 residents. The mean amount of fiber provided to residents was 21.4 g/d [standard error (SE): 1.2; 95% confidence interval: 18.8, 24.2 g/d], the mean amount of fiber consumed by residents was 15.8 g/d (SE: 0.6; 95% confidence interval: 14.7, 16.9 g/d).

CONCLUSIONS

Older adults living in care facilities are provided with dietary fiber below the recommended guidelines. Compounding this is that residents consume much less than what is provided and do not meet the recommendations for dietary fiber consumption. There is scope to improve dietary fiber provision, promote consumption to residents to aid laxation, and potentially reduce laxative use and the unwanted side effects of diarrhea. This trial was registered at PROSPERO as CRD42023427265.

Current agreement between ActiGraph and CUPAR in measuring moderate to vigorous intensity physical activity for adolescents

The study aims to develop and validate the Curriculum-related Physical Activity Recall questionnaire (CUPAR) as a measure of physical activity in adolescents. 83 middle-school students (13.23 ± 0.74 yrs) completed the CUPAR and whore ActiGraph accelerometers for seven consecutive days. Correlations and Bland-Altman plots were to examine the agreement between these two measures. Significant correlations were observed between the CUPAR and ActiGraph accelerometer for 5-day MPA (r = 0.29, p < 0.01), and for both 5-day and 7-day VPA (r = 0.47 and 0.79, ps < 0.01), and MVPA (r = 0.79 and 0.42, ps < 0.01). Plots showed reasonable agreement between the CUPAR and ActiGraph estimates of VPA and MVPA. The agreement between CUPAR and ActiGraph was higher for in-school VPA (r = 0.58, p < 0.01) and MVPA (r = 0.44, p < 0.01) as compared to the out-school VPA (r = 0.22, p < 0.05) and MVPA (r = 0.26, p < 0.05). The CUPAR can reduce respondents' burden, representing a reliable and efficient measure of physical activity among adolescents, especially for PA occurred during in-school sessions and at vigorous intensity.

Too low protein and energy intake in nursing homes residents

OBJECTIVES

An optimal diet contributes to reducing malnutrition prevalence in the nursing home population. For this population, recommended daily intakes are ≥1.0 g protein/kg body weight and ≥27 energy kcal/kg body weight. The aim of this study was to identify the protein and energy intake of nursing home residents and to assess groups at increased risk for low intake.

METHODS

Cross-sectional data regarding food intake was collected by three-day observations in 189 residents (aged ≥65 y, mean age 85.0 y) of five different nursing homes. Linear mixed models were used to examine associations of protein and energy intake as dependent variables with demographic and disease-related problems as determinants. Results were adjusted for age, sex, and mobility levels and stratified by a protein/energy-enriched diet (P/E+).

RESULTS

The daily protein intake of the residents was 0.80 (SD 0.22) g/kg body weight, with 84.7% having an intake below the recommended daily 1 g/kg body weight. Mean daily energy intake was 20.7 (SD 6.1) kcal/kg body weight, with 85.2% having an intake below recommendation. Protein/energy intake was higher in the P/E+ group compared with standard diet: 0.92 (SD 0.23) versus 0.74 (SD 0.19) g/kg body weight, and 23.9 (SD 6.1) versus 19.1 (SD 5.4) kcal/kg body weight, respectively. The oldest age groups (>85 y), chair-bound residents, women, and residents having difficulties with chewing, dysphagia, a reported decreased food intake, or a decreased appetite were at a higher risk for a low protein/energy intake.

CONCLUSION

Nearly all nursing home residents were at increased risk for not meeting the minimum protein/energy requirements. Intakes should, on average, be increased with ≥15 g protein and ≥520 kcal to reach the minimum intake targets. Although using a P/E+ diet was associated with higher intakes, even these residents had intakes below the requirements.

Clinical Impact of Nutritional Status and Energy Balance in Elderly Hospitalized Patients

OBJECTIVES

This study aimed 1) to assess the nutritional status of patients hospitalized in a geriatric ward using the recent Global Leadership Initiative on Malnutrition (GLIM) criteria, 2) to determine the balance between the energy intake (EI) with an enriched diet and the energy requirement (ER) using indirect calorimetry, and 3) to assess whether undernutrition is associated with 1-year outcome.

DESIGN

This is a prospective cross-sectional study.

SETTING

This study was performed in a geriatric unit.

PARTICIPANTS

Patients of this geriatric unit were eligible for the study if they agreed to participate and if they did not meet the exclusion criteria (presence of malignant tumour, uncontrolled heart or renal failure, thyroidal disease, uncontrolled sepsis, oedema of the lower limbs, wearing of a pacemaker, biological thyroid dysfunction and inability to perform walking tests).

MEASUREMENTS

Rest energy expenditure (REE) was measured by indirect calorimetry within the week of hospitalization. Total energy expenditure (TEE) was obtained by multiplying REE by a physical activity level coefficient and energy expenditure that was related to thermogenesis (i.e., 10% of the total amount of energy ingested over 24 h) was added. Food intake was measured over a 3-day period. Undernutrition was defined using MNA and the criteria of the GLIM leadership. Clinical outcomes included 1-year institutionalisation and mortality.

RESULTS

Seventy-nine patients (84.9 ± 5.3 years) were included. A total of 21 (26.6 %) patients were found undernourished. REE was 1088 ± 181kcal/day (17.8 ± 2.9 kcal/kg/day) and TEE was 1556 ± 258 kcal/day (25.4 ± 4.2 kcal/kg/day). Weight-adjusted REE and TEE were higher in undernourished patients compared to those well-nourished (19.8 ± 3.1 vs. 17.1 ± 2.6 kcal/day and 28.4±4.5 vs. 24.4±3.7 kcal/day) (p<0.05). The lower was the Body Mass Index (BMI), the higher was the energy needs (p<0.01). EI was significantly greater than energy requirements (difference requirements - intake with enriched diet = -354 ± 491 kcal/day; p<0.0001). This difference did not depend on BMI (p=0.82), appendicular skeletal mass index (ASMI) (p=0.63), or the presence of undernutrition (p=0.33). At 1-year follow-up, 15 (19%) patients died and 20 (25.6%) were institutionalized. On multivariable analysis, male gender (OR=5.63; p=0.015) and undernutrition (OR=7.29; p=0.0043) emerged as independently associated with death. On multivariable analysis, only ASMI (OR 0.59 (0.35-0.99), p=0.044) and activities of daily living (ADL) (OR 1.14 (1.00-1.30), p=0.043) were significantly associated with institutionalization.

CONCLUSIONS

Undernutrition as assessed by the GLIM criteria remains common in elderly patients hospitalized in a geriatric unit and is associated with increased 1-year mortality but not with institutionalization. Energy requirements are higher in undernourished patients and in patients with a low BMI. Enriched energy intakes could sufficiently cover the energy needs of this population.
