second criterion resulted in respective AUCS of 0.53 (0.49
–
0.58) and
0.59 (0.53
–
0.64).
Key conclusions:
The ESPEN criteria for diagnosis of malnutrition
show good construct validity in older adults based on significant
associations with relevant adverse health outcomes. The criteria
may be simplified by leaving out FFMI and BMI (in those with a
BMI < 28 kg/m
2
) from the second criterion as similar validity was
observed.

What is the most reliable obesity index in Korean elderly
population?
J. Kim.
Sanggye Paik Hospital Inje University
Background:
Obesity is a major risk factor for cardiovascular diseases.
However, there is no confirmed index for diagnosing obesity in elderly
population. Thus, we examined the accuracy of the currently used
obesity indices and tried to find the most reliable index reflecting
obesity among elderly Korean population.
Methods:
We analyzed the data from the Fourth Korean National
Health and Nutrition Examination Survey. The subjects of this study
included elderly population of 1,193 people over 60 years of age. We
analyzed the correlations among the appendicular skeletal muscle
mass, truncal fat mass, total muscle mass, waist circumference, BMI,
and total body fat percentage, The relevance between each obesity
index was evaluated with each metabolic markers, such as fasting
plasma glucose, total cholesterol, HDL-C, triglycerides, LDL-C, and
HOMA-IR,
Results:
No significant correlation was found between BMI and total
body fat percentage although significant correlation was noted
between BMI and waist circumference. Total body fat percentage
correlated with appendicular skeletal muscle mass, truncal fat mass,
and total muscle mass, Waist circumference showed significant
correlations with fasting plasma glucose, HDL-C, triglycerides, and
HOMA-IR. BMI correlated with HDL-C, triglycerides, and HOMA-IR.
In females, BMI had significant correlations with fasting plasma
glucose and total cholesterol. Total body fat percentage, appendicular
skeletal muscle mass, truncal fat mass, and total muscle mass failed
to show any significant correlations with metabolic indices.
Conclusion:
Waist circumference and BMI were the most reliable
obesity indices regarding metabolic markers among the elderly
Korean population.

The relationship between obesity and thyroid nodules in healthy
Korean adults
J. Yoon.
Inju University Sanggye Paik Hospital
Background:
Thyroid nodules are common disease in Korean
population and their presentations are important in the public
health aspects. Previous studies have provided an evidence for the
association between thyroid cancer and obesity, but little is known
about the relationship between thyroid nodules and obesity. We
investigated the relation of thyroid nodules and obesity in healthy
Korean adults.
Method:
We obtained data from 2922 subjects (Male: 1883, Female:
1039) who underwent a routine health checkup at the Health
Screening and Promotion Center of Sanggye Paik Hospital. We
reviewed their height, weight, obesity indices (Body mass index:
BMI, Total body fat: TBF), and thyroid ultrasonography results. Obesity
indices are divided into four groups.
Results:
Both men and womenwho have a higher BMI had a increased
prevalence of thyroid nodules (p = 0.004 in men, p < 0.001 in women).
In addition, thyroid nodules increased significantly with higher TBF in
men and women (p = 0.001 in men, p < 0.001 in women).
Conclusion:
We observed positive relationship between obesity
indices (BMI, TBF) and thyroid nodules in both men and women.
Our results suggest that obesity might be important in the prevalence
of thyroid nodules as well as thyroid cancer.

Background:
Anemia is a common concern in geriatric health,
but its exact incidence and prevalence are unclear. In United States,
10.2% of women aged 65 and older are anemic. Several other cross-
sectional studies in the elderly persons have reported the asso-
ciation of anemia with functional disability and poorer physical
performance, decreased muscular strength, fall injury events at home,
and increased frailty risk. Interestingly, cognitive impairment has
also been shown to be linked with anemia. Anemia may result
from chronic infectious disease, chronic inflammatory disease,
chronic renal failure, and endocrine disease. The present study
investigates the prevalence of Anemia among the elderly in Qatar.
Research design and methods A cross sectional review of electronic
Cerner and medical record from January 2013-december 2013 of
individuals were used to identify studies that reported on prevalence
of anemia in cohorts of at least 450 individuals predominantly
aged 60 years and over living in Qatar, together with criteria used
to define anemia, the level below 12 g/dL inwomen and below 13 g/dL
in men. The study has been approved by the medical research
institutional ethics committee. Measurements: Patient characteristics
and outcomes were analyzed and compared according to the severity
of Anemia. Patient population included both males and females.
Patients who underwent baseline hemogram profile on study period
were included for the study. Laboratory parameters collected include
hemoglobin, hematocrit value, mean corpuscular volume (MCV),
mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin
concentration (MCHC), reticulocyte count, iron profile, serum folate,
and serum creatinine. Charlsons comorbidity index, Activity of Daily
Living and Bergs Balance Scoring level were compared with severity
of Anemia.
Results:
A total of 447 elderly patients with mean age 77.9 ± 8.6 years
were studied. The females (68.5%) are participated more than males
(31.5%) in this study. The 78% of populations are Qatar nationalities
compared to expatriates (22%). The index hemoglobin concentration
in elderly was 10.9 ± 1.6 g/dL and lowest hemoglobin concentrations
were 9.7 ± 1.6 g/dL. The severity of anemia was classified as mild
deficiency was 17.0%, moderate 61.1% and severe anemia 21.9% among
total cases. The severity in the hemogram values among patients
showed statistical significance only for hematocrit (p = 0.001), Serum
Iron (p = 0.001) and Serum Ferritin (p = 0.02). There was significant
negative correlation between hemoglobin level and creatinine level
(p = 0.001) among elderly patients.
Conclusions:
Among the elderly patients 98 (21.7%) had severe
anemia (hemoglobin below 8 g/dL), but majority of elderly suffering
from moderate anemia 273(61%). The common type of anemia
was diagnosed as normocytic normochromic anemia (72.7%) than
microcytic anemia (26.8%), it indicates that anemia of chronic disease
is highly prevalent than iron deficiency anemia in elderly. Further
population based studies are warranted to evaluate the point pre-
valence of anemia and its prevention among the elderly.
