How to Try This: The Mini Nutritional Assessment

Evaluation of oral health, taste perception, nutritional status and emotional well-being in post-menopausal women

BACKGROUND

In postmenopausal women (PMW), vasomotor symptoms, emotional oscillations and sleep disturbances can affect physiological and psychological functioning. However, the effect of menopause on oral health-related parameters is not been thoroughly studied.

OBJECTIVE

To evaluate oral health, taste perception, eating habits, nutritional status and emotional well-being in PMW compared with a group of young and healthy pre-menopausal women (PrMW).

MATERIALS AND METHODS

Two groups (Group I: PMW and Group II: PrMW) with 30 participants each, participated in the cross-sectional study. The study proforma contained measures of oral health, taste perception, nutritional status and anxiety levels of the women in both groups using validated and previously used tools were designed and implemented. The data were analysed with student t, Mann-Whitney U, and chi-squared tests to evaluate the differences between the two groups.

RESULTS

The cross-sectional study indicates no major differences in oral health, taste perception, nutritional and emotional status between PMW and PrMW. Nonetheless, there was a significant difference in perception of 'front teeth lengthening in size' and change in hot and cold sensations between the groups. Furthermore, the study group with PMW tends to have fewer natural teeth than the reference group.

CONCLUSION

Overall, menopause does not appear to affect oral health, taste perception, nutrition or emotional health. It is suggested that oral health and taste perception, as well as nutritional and emotional status, are associated with gradual aging processes that may or may not be affected by menopause.

Nutritional status of the free-living elderly

OBJECTIVES

Measuring malnutrition is difficult in all settings and confused with the signs of aging. Mini nutritional assessment is an effective tool designed to identify older adults who have a risk of developing malnutrition.

METHODS

Three hundred and one free-living elderly who lived with their family or alone were included in the study. Nutritional screening was performed with mini nutritional assessment and mini nutritional assessment short form. Dietary intake was assessed by a 3-days weighted food record.

RESULTS

According to mini nutritional assessment in the 65-74 years young-old group, malnutrition, risk of malnutrition, and normal nutrition was 2.4%, 39.5%, 58.2%, respectively, and in the 75-84 years old-old group it was 10.2%, 48.7%, 41.0%, respectively, and in the older than 85 years oldest-old group 92.3%, 7.7%, 0%, respectively. The lowest nutritional intake by recommended dietary allowance was zinc and the highest intake was sodium. Neither young-old group nor old-old group nor oldest-old group met the B12 and zinc requirements.

CONCLUSIONS

The free-living elderly at an age of 85 years and above are, accompanied by the existence of factors which may mask their weight losses, under a severe risk of malnutrition unless they receive adequate medical care and attention.

Malnutrition and Dysphagia in long-term care: a systematic review

Determining the co-occurrence of malnutrition and dysphagia is important to understand the extent to which swallowing impairment contributes to poor food intake in long-term care (LTC). This review investigated the impact of dysphagia on malnutrition in LTC by synthesizing the results of published literature. Seven electronic databases were used to search for English-language publications reporting malnutrition and dysphagia in LTC facilities from 1946 to 2013. Fourteen studies were eligible for inclusion. Overall, the literature on the co-occurrence of malnutrition and dysphagia in LTC shows a paucity of high-quality evidence. Articles reviewed lacked consistent definitions for both conditions. Methods used to confirm each diagnosis also differed and were of questionable validity. Based on a review of the literature, evidence of the existence of concurrent concerns with respect to malnutrition and dysphagia emerges. The reported frequency of participants in LTC with dysphagia ranges from 7% to 40%, while the percentage of those who were malnourished ranges from 12% to 54%. Due to discrepancies used to describe and measure these conditions, it is difficult to determine the exact prevalence of either condition separately, or in combination. Consequently, the impact of dysphagia on malnutrition must be considered and studied using valid definitions and measures.

Accumulation of geriatric conditions is associated with poor nutritional status in dependent older people living in the community and in nursing homes

AIM

To clarify the association between nutritional status and the prevalence of geriatric conditions in dependent older adults.

METHODS

A cross-sectional observational study of dependent older adults aged 65years or older who were living either in the community (n = 511, mean age 81.2years) or in nursing homes (n = 587, mean age 85.2years) was carried out. Data included the participants' demographic characteristics, basic activities of daily living, Charlson Comorbidity Index and the prevalence of eight geriatric conditions (visual impairment, hearing impairment, falls, bladder control problems, cognitive impairment, impaired mobility, swallowing disturbance and loss of appetite). Nutritional status was assessed by the Mini Nutritional Assessment short form (MNA-SF).

RESULTS

Of 1098 participants, 21.4% (n = 235) were categorized as "malnourished", according to the MNA-SF classification. Participants in the "malnourished" group had a greater number of geriatric conditions than those in the other two groups. A higher prevalence of all the geriatric conditions except for falls was detected in the group with poorer nutritional status. Multivariate logistic regression analysis showed that malnutrition was associated with the number of geriatric conditions, but not with that of comorbidities, even after controlling for confounders.

CONCLUSIONS

Malnutrition was confirmed to have significant associations with geriatric conditions in dependent older adults.

Nutritional status of older persons presenting in a primary care clinic in Nigeria

The study objective was to determine the nutritional status and its association with sociodemographic characteristics and health complaints of older persons presenting at the General Outpatients Department (GOPD) Clinic of University College Hospital (UCH), Ibadan, Nigeria. A cross-sectional descriptive design was used to select 500 consecutively presenting participants aged 60 years and older between September and December, 2009. The Mini-Nutritional Assessment (MNA) tool and body mass index were used to assess undernutrition and overweight, respectively. The prevalence of nutritional problems was 61.9% (undernutrition = 7.8% and overweight = 54.1%). Being unmarried (P < 0.001), engagement in a job after the age of 60 years (P < 0.001), constipation (P = 0.009), rectal bleeding (P = 0.008), and oral problems (mouth, teeth, and tongue) were significantly (P < 0.001) associated with undernutrition. Younger age (P = 0.050) and female gender (P = 0.011) were significantly associated with being overweight. Logistic regression analysis showed being unmarried OR = 1.355 (95%CI 1.075-1.708) to be the most important factor for the development of undernutrition. The high prevalence of nutritional problems in this study underscores the need for intervention in this population. Correlation analysis (Pearson's) showed a positive association between BMI and MNA scores (r = 0.152, P = 0.001).

Health Inequalities, General Trends in Mortality and Morbidity, and Associated Factors

All measures of health status are ultimately derived from observations of individuals. At the field level we have such measures as self-assessed health status, report of a specific disease, record of a particular death, or an individual’s test on a biomarker, such as blood pressure or serum cholesterol. The observations for individuals are combined and summarized to represent subnational geographic areas, demographic or socioeconomic groups within countries, or national populations. The summary measures, whether they are percentages, averages, or rates, apply to groups. A problem arises when the measures that are based on groups are assumed to represent individuals. The analysis becomes especially problematic when the units analyzed are geographic areas and inferences are being made about individuals from the analysis for these geographic areas.

Is serum albumin a marker of malnutrition in chronic disease? The scleroderma paradigm

BACKGROUND

Malnutrition is common in many chronic diseases, but physicians may rely on a low albumin value before deciding that malnutrition is present.

OBJECTIVE

To determine the relationship between serum albumin and malnutrition in systemic sclerosis (SSc) as a paradigm for other chronic diseases.

DESIGN

Cross-sectional, multicenter study of patients from the Canadian Scleroderma Research Group Registry. We used the Malnutrition Universal Screening Tool (MUST) to evaluate patients for malnutrition. Disease extent was measured in several ways, including physician global assessment. Multiple linear regression was performed to identify independent predictors of serum albumin.

RESULTS

Two hundred fifty-eight patients were studied. The mean (SD) serum albumin level was 44.4 (4.2) g/L. Only 2% of the values were below normal and all these patients were in MUST category > or =2, or high risk for malnutrition, which included 21.3% of the cohort. MUST, shorter disease duration, greater disease severity (physician global assessment of disease severity and modified Rodnan skin score), and greater disease activity (physician global assessment of disease activity, C-reactive protein, and Scleroderma Disease Activity Index) all correlated significantly but weakly with albumin. Multivariate analysis demonstrated that a higher MUST score and worse disease severity were independently associated with lower serum albumin, but only 7% of the variance of albumin was explained in the adjusted model.

CONCLUSIONS

Serum albumin is not useful as a marker for malnutrition in SSc and should not be assumed to be useful as a marker in other chronic diseases. More attention should be paid to clinical features of malnutrition, including assessment of body mass index and unplanned weight loss, and overall disease severity.
