Objectives:

To study whether the association between Body Mass

Index (BMI) and hip fracture differs according to gender and age.

Methods:

Cohort Norway comprises ten population-based health

surveys (1994–2003). Information includes socio-demographic

factors, lifestyle, health and diseases. Weight and height were

measured. Hip fractures treated in Norwegian hospitals (1994–

2008) were retrieved from patient administrative systems. Analyses

were limited to 29,511 women and 32,276 men 50–79 years with

valid baseline data. Regression models were used to estimate

relative risk (RR) of hip fracture. Age-standardized fracture

incidence rates per 1,000 person years were calculated.

Results:

During follow-up (median 8.4 years) 1,603 women and 951

men suffered a hip fracture. Participants with BMI

22 kg/m

had

a two-fold risk of hip fracture compared to overweight individuals

(BMI 25–29.9 kg/m

) (Women: RR = 1.85, 95% Cl 1.60–2.14, Men:

RR = 2.16, 95% Cl 1.77–2.63).

In women 70–79 years the risk of hip fracture decreased in those

with BMI above 25 kg/m

. In all other categories of age and gender

there was no significant corresponding decrease at BMI above

25 kg/m

. The largest difference in absolute risk across BMI groups

was found among women 70–79 years.

Conclusions:

In this large prospective population-based study,

a higher BMI was protective of hip fracture, but the

association differed extensively with age and gender. To be thin

(BMI

22 kg/m

) was an important risk factor, and underweight

should be monitored and prevented to avoid hip fractures.

Cutoff point of gait speed to predict falls, dependence, and

mortality in Korean community-dwelling elderly: 3 year

prospective finding from living profiles of older people survey

in Korea

Seoul, Republic of Korea

Objectives:

The mean of gait speed in Asian elderly including

Korean is lower than in Western. For example, the cutoff of the

lowest quartile in American elderly is 0.6m/sec in both men and

women, while that in Korean elderly is around 0.5 m/s in men and

around 0.4 m/s in women.

Methods:

We analyzed with National Older People Survey in year

2008 (15,146 elderly participants aged 60 years or older) and

its follow-up data in 2011. Using a multi-stage cluster sampling

design, the elderly were selected from households stratified into

25 districts(seven metropolitan and 18 provincial). The gait speeds

of the elderly in year 2008 were categorized by their quintiles

and were analyzed in terms of mortality, falls, and instrumental

activities of daily living in year 2011.

Results:

The number of falls continuously decreased with gait

speed increased. In western country, a Gait Velocity

1.1m/s was

considered normal and a cut-off

0.8 m/s predicts falls. The cut-off

to predict falls in Korean elderly is lower than 0.8 m/s.

The number of indoor fallers decreased with gait speed increasing.

The number of outdoor fallers decreased with gait speed increasing

until the gait speed of 1.0–1.3 m/s, but slightly increased after that.

Cut-off poinst of gait velocity in Korean elderly to predict mortality,

falls, and instrumental activities of daily living after 3 years will be

presented.

Conclusions:

The cut-off point to predict adverse outcomes in

Korean elderly seems to be lower than that in Western elderly.

Hospital, Oslo, Norway

Objective:

Cross sectional analysis of sarcopenia in hip fracture

patients.

Methods:

Consecutive patients with hip fracture admitted 2011–

2013 at three hospitals in Norway. Inclusion criteria were written

informed consent, age

65, being able to walk, no unstable

illness, a remaining life expectancy

3 months and living in the

community. Sarcopenia status was determined at follow-up by

the method of the European Working Group on Sarcopenia in

Older People. Low muscle mass was determined by anthropometry

by the method of Heymsfield, as ≤5.67 kg/m

for women and

≤7.25 kg/m

for men. Low handgrip strength was

20 kg for women

and

30 kg for men. Low physical performance was by New Mobility

Score of

5. Correlations with clinical associations were analysed

with Spearman’s rho.

Results:

1592 patients were admitted for hip fracture during the

period of inclusion, 282 were included and 225 returned for

follow-up. 37% of patients had low muscle mass, 51% had low

hand grip strength and 21% had low physical performance. 64%

had no sarcopenia, 9% pre-sarcopenia, 16% had sarcopenia and

9% had severe sarcopenia. Male gender (0.318), nutrition score

of NRS2002 (0.256), medications on discharge (0.164), ASA score

(0.201) and Charlson co-morbidity index (0.146) were associated

with sarcopenia. Body mass index (0.401) and increasing Barthel

ADL (0.148) was protective. There was no association with bone

mineral density or vitamin D.

Conclusions:

25% of robust hip fracture patients have sarcopenia.

Sarcopenia is correlated with increasing age, male gender,

malnutrition, polypharmacy, high ASA score, co-morbidity and

impaired activities of daily living.

Objectives:

The sarcopenia diagnosis algorithm developed by the

European Working Group on Sarcopenia in Older People and used

in the present study needs further validation trough cross-sectional

and longitudinal studies. The aim of the present study is to assess,

using this algorithm, the prevalence of sarcopenia and the clinical

components linked to this geriatric syndrome.

Methods:

Participants were community dwelling subjects aged 65

years or older. Muscle mass was measured by DXA, muscle strength

by a handgrip dynamometer and gait speed was assessed on a 4-

meter distance. Large amounts of socio-demographic and clinical

data were collected.

Results over one year:

534 subjects were recruited for this study

(60.5% of women, mean age of 73.5

6.16 years), among whom

73 subjects were diagnosed sarcopenic (prevalence of 13.7%).

Sarcopenic subjects were older, had a lower BMI, presented

more cognitive impairments, more comorbidities, were more often
