Abstract

This study prepared Functional Foods (FF) with softened chicken moose and milkfish without fin for older adults and compared the different effects of FF from those of Music Aerobic Exercise (MAE) on the complete blood counts, blood biochemistry, including nutrition index of albumin, and cholesterol levels, and frailty scores before and after institution of FF and MAE among residents of long-term care institutes. The FF significantly increased the high-density lipoprotein cholesterol and albumin levels. In contrast, MAE significantly increased Red Blood Cells (RBC), and decreased the rates of frailty items on fatigue feeling and low physical activity. In comparison between FF and MAE groups, we found that the FF significantly improved better on HDL-C and MCV while the MAE improved significantly better on hematopoiesis as increases in red blood cells and platelets. A combination of FF and MAE might improve better nutrition, physical function, and frailty for older adults.

Introduction

Older adults with Chewing Difficulty (CD) are prone to insufficient intake of meat and plant fibers. They are more likely to cause many health problems, such as malnutrition, frailty, and sarcopenia. Similarly, older adults with Insufficient Physical Activity (IPA) are prone to frailty, sarcopenia, and anabolic resistance to muscle metabolism. The prevalence of CD and IPA in older adults with sarcopenia has increased by over 30% and 50%, respectively [1].

Older adults with CD and/or IPA are closely correlated to frailty and linked with geriatric syndrome. There is an urgent need to promote healthy physical activity and prepare functional foods for older adults to prevent malnutrition and frailty. We have previously shown that moderate exercise such as Tai Chi Chuan, Yoga, and Music Aerobic Exercise (MAE) could enhance immune function, stress adaptation, and neural function. Tai Chi Chuan exercise for 12 weeks improved immune regulation and neuropathy Yoga exercise could improve stress adaptation and MAE could enhance immune function decrease depression, and increase brain-derived neurotrophic factor levels. We also found that CD is prevalent in nursing homes and correlated to the institution of gastric tube feeding and frailty. Here, we postulated that the FF made in softened meat and jelly fruit juice for older adults could be comparative to or different from the effects of the MAE on frailty and blood biochemistry [2].

This study aimed to compare the different effects between the Moderate Exercise of music (MAE) and Functional Food (FF) made in softened chicken meat or fish with antioxidant herbs and fresh jelly fruit juices on complete blood counts, blood biochemistry including nutrition index of albumin, and cholesterol levels, and rates of the frailty items among residents of long-term care institutes [3-5].

Materials and Methods

Study design

This quasi-experimental research was conducted in communities around the northeastern coast of Taiwan. Eighty-five older adults in eight long-term care institutes were recruited to participate in the FF group (n=36 in 2 senile centers) or MAE group (n=49 in 2 senile centers) after obtaining informed consent for the participation agreement from the institutes and residents. This comparative study was initially designed to do a parallel comparison between FF and MAE groups for 10 weeks. During the COVID-19 pandemic, the quarantine policy for group meals at long-term care facilities was changed to prohibit extramural preparation of group meals so that the study period of the FF group was cut off at 5 weeks. The MAE group performed the study as scheduled three times a week, each for 50 minutes of performance for 10 weeks. Inclusion criteria are older adults who were over 65 years old, signed the participation agreement, and moved independently. Exclusion criteria for participation are those who were bedridden, unable to move or eat softened food [6].

Preparation of functional foods

Functional foods, including softened chicken meat, softened milkfish, and jelly fruit juice for older adults with CD, were made in tongue-crushed food with a physical property tester of less than 2.0 × 104 N/m2 [16]. Choosing a technique of vacuum low-temperature cooking of the meat and fish with phytochemical-rich herbs makes meat sufficiently soft to be broken up by the tongue and gives a good taste of herbs’ fragrance. The FF included softened milkfish (Figure 1) and chicken moose with herbs containing ginseng and wolfberry, and the jelly fruit juice was made from golden and green fruits (apple, pineapple, kiwi, and strawberry) prepared by a central kitchen. The low-temperature cooking foods were put into the vacuum packaging of aluminum foil for better storage of 6 months. The two FF products fulfilled the microbiological standards for frozen foods requirement at less than 10 colonyforming units of E. coli. The FF group consumed original meals plus chicken moose and milkfish 5 packs and two bottles of fresh fruit jelly per week for 5 weeks [7].

D) The MAE practice with musical rhythm were carried out in 2 long-term care centers.

Moderate exercise of Music Aerobic Exercise (MAE)

The physical activity for older adults with IPA should be moderate exercise and harmonious balance without cardiopulmonary exacerbation. Previous studies showed that the MAE was a moderate exercise for community adults, effectively improving stress adaptation and immune regulatory function. The MAE included rhythmic exercise for 50 minutes (10 minutes of warm-up, 30 minutes of musical exercise, and 10 minutes of cool-down exercise) 3 times a week for 10 consecutive weeks. Before and after the program, the participants received tests on frailty, biochemistry, and complete blood counts [8-9].

Assessment of complete blood counts and biochemistry

Blood samples (5 ml) were subject to measurement of CBC and biochemistry. The biochemistry, including high-density lipoprotein cholesterol (HDL-C, mg/dl), low-density lipoprotein cholesterol (LDL-C, mg/dl), and albumin (gm/dl), were measured by Roche c702 (Roche Diagnostics, Indianapolis, USA). The complete blood counts including WBC (cells/ul), RBC (x106/ul), Hemoglobin (gm/dl), Hematocrit (%), MCV (pl/cell), MCH (pg/ cell), MCHC (gm/dl), Platelet (x103/ul), Neutrophil (cells/ul), Lymphocyte (cells/ul), Monocyte (cells/ul), Basophil (cells/ul) and Eosinophil (cells/ul) were measured by Sysmex XP300 (Sysmex Diagnostics, Seattle, USA) [10].

Measurement of the rate changes of the frailty items

Employing Fried’s frailty assessment scales, including body weight loss, fatigue feeling, low physical activity, decreased muscle strength, and slowed walking speed we assessed the rate changes of the frailty items before and after the FF or MAE program. The cut-off values for the frailty items were defined as 1) Weight loss: Less than 20% of peers; 2) Fatigue feeling: Tired 3 or more days a week; 3) Decreased muscle strength: Grip strength test in male (female) <26 (18) kg determined by a digital hand dynamometer (Handexer Inc., Sacramento, CA); 4) Slowly walking speed less than 0.8 m/s (6 minutes <288 m); and 5) Low physical activity: Less than 20% of peers. The rates (percentages) of the 5 frailty items were assessed before and after the FF and MAE programs [11].

Data analyses and statistics

This study recruited older adults in eight long-term care facilities, where the institutes and residents were willing to participate in moderate exercise or function food study. The sample size was estimated based on the effect size on the changes in cholesterol levels or blood counts at 0.2 before and after MAE or FF intake, study power of 0.8, and alpha level of 0.05. The estimated number of effective samples was calculated as 40. Statistical analyses are performed using SPSS version 22 (IBM, Inc., Armonk, NY, USA). The Chi-square test was applied to compare the difference of rates (percentages), paired t-test was applied to test the normally distributed changes before and after the FF or MAE program, and the Generalized Estimating Equation (GEE) statistics were used to compare the differences between the effects of FF and MAE [12].

Results

Demographic data of the FF and MAE groups

This study was designed to do a parallel 10-week comparison between FF and MAE groups for the different effects on nutrition biochemistry, CBC, and frailty rates. The FF study was cut off to a 5-week study due to the change of quarantine policy in the COVID-19 periodic outbreaks. Forty-nine participants in two long-term care institutes completed the 10-week MAE study, and thirty-six participants completed the 5-week FF study. The demographic data of the two studies are shown in Table 1. More female residents participated in the MAE group, and more male residents participated in the FF group. The population studied had an average of 76 years old. Neither FF nor MAE group had a significant difference in age, weight, height, or blood pressure [13].

Effects of the FF on biochemistry, CBC and frailty

As shown in Table 2, we found that the intake of FF increased the HDL-C from 48.8 ± 12.7 mg/dl to 50.8 ± 14.6 mg/dl (p=0.049). The albumin levels increased from 4.13 ± 0.32 g/dl to 4.25 ± 0.27 g/dl (p=0.027) after the intake of FF for 5 weeks. Total White Blood Cells (WBC) and Red Blood Cells (RBC) were not significant difference before and after the intake of FF. Differential counts of WBC were not significantly different except basophils increased significantly from 0.69 to 0.76 cells/ul. Hemoglobin (Hb) and Hematocrit (Hct) levels were not significant differences, but Mean Corpuscular Volume (MCV) significantly increased from 91.9 to 92.4 (pl/cells) after the intake of FF. As shown in Table 3, we found that the frailty rate in the study population was 35% (â?§ 3 of 5 items). The intake of FF improved the frailty at slow walking speed (p=0.021) but not weight loss, fatigue feeling, low physical activity, or grip strength (Table 3) [14].

Effects of MAE on biochemistry, CBC, and frailty

The MAE for 10 weeks did not significantly increase blood albumin or cholesterol levels (Table 4). The MAE did increase the RBC significantly from 4.26 to 4.33 (x106 cells/ul), but decreased the MCV from 94.8 to 94.2 pl/cell. The platelet counts increased from 203.1 to 212.6 (x103/ul), which did not reach a significant increase (p=0.085). The MAE for 10 weeks had no significant effects on differential counts of WBC. The MAE improved the frailty at fatigue feeling (p=0.001) and low physical activity (p=0.006) but not at slowly walking speed, weight loss, or grip strength (Table 4) [15].

The comparative effects between FF and MAE

We used Generalized Estimating Equation (GEE) statistics to compare the different effects of the FF and MAE on CBC and biochemistry (Table 5). We found that the participants in the FF group revealed a significantly better impact on the HDL-C level (Wald X2=4.32, p=0.038). In contrast, participants in the MAE group compared to the FF group significantly increased RBC (Wald X2=3.86, p=0.049) and platelets (Wald X2=6.69, p=0.01), suggesting that MAE for 10 weeks tends to enhance hematopoiesis on RBC and platelets [16].

Discussion

Results from this study showed that the intake of FF increased the HDL-C and albumin levels, suggesting improvement in metabolism and nutrition. In contrast, the MAE appeared to increase RBC and platelets, suggesting the MAE might enhance erythropoiesis and thrombopoiesis in older adults with age over 70 in this study [17].

Frailty is closely associated with IPA and nutritional status. Inappropriate nutrient intake has been shown to cause a risk of malnourishment and frailty in older adults [18]. Poor appetite, and low protein intake and low vitamin D intake have been correlated to frailty. A clinical trial with higher protein intake for 12 weeks has been shown to increase muscle mass and physical activity in frail elders. Proper supplementation of functional food may be applied to improve nutrition and functional activity. We showed in this study that additional supplementation of chicken moose and milkfish in softened texture with herbs fragrance 5 times a week for 5 weeks did improve the blood albumin level, HDL-C level, and better walking speed. Although this short-term administration of higher protein intake did not improve fatigue feeling, weight gain, or muscle strength, a more prolonged supplementation or a combination with physical exercise may improve both nutrition and physical activity [18].

Different exercises have been shown to prevent physical dysfunctions and reverse frailty in older adults. However, older adults with different ages and comorbidities may require different styles of exercises, aerobic, resistant, or balanced training. Combined training on strength, endurance, and balance has been shown the best to prevent falls and improve balance and physical performance in the frailty elderly. The problem is how to encourage older adults to exercise regularly and practice moderate exercise without falls or cardiopulmonary exacerbation safely. Employing the MAE, which is a moderate exercise with harmonious posture in musical rhythm we showed that the MAE exercise 3 times (50 minutes a session) a week for 12 weeks, increased erythropoiesis and thrombopoiesis in addition to improving fatigue feeling and physical activity. The MAE alone did not improve nutrition status on blood albumin levels or blood cholesterol levels in the study population with an average of 76 years of age [19].

Limitations of the study include 1) This study was not a randomized control trial, 2) The FF group completed only 5 weeks of additional high protein FF, and 3) The participants in the MAE group had a high rate of female participants. Moreover, the outcome measurements were limited to blood biochemistry and frailty scales but not biomarkers of senescence or aging. We recently identified that older adults had a significantly higher Senescence-Associated Secretory Phenotype (SASP) in urinary extracellular vesicles than young adults. We thus propose that a combination of active aging exercise and functional food might improve nutrition, immunity, and frailty based on the pre- and post-interventional monitoring of aging biomarkers by non-invasive point-of-care tests of SASP in urinary extracellular vesicles [20].

Conclusion

Results from this study suggest that FF and MAE for older adults have different effects on nutrition status, hematopoiesis, biochemistry, and frailty. Further studies will investigate whether a combination of both FF and MAE for older adults improves physical function, nutrition, frailty, and mental health scales.
