Mean gait speed changed from 0.33m/s (baseline) to 0.39m/s
(p = 0.047), from 0.29m/s to 0.42m/s (p = 0.024), and from 0.34m/s
to 0.36m/s (p = 0.450) whereas mean grip strength changed from
4kg (baseline) to 5 kg (p =0.180), from 5.17 kg to 12.17 kg (p =0.027)
and from 2.6 kg to 2.2 kg (p =0.713) in groups A, B and C respectively.
Mean frailty score changed from 5.0 to 3.0 (p = 0.131), from 4.67 to
2.67 (p =0.034), and from 4.4 to 4.0 (p = 0.157) in groups A, B and C
respectively.
Conclusion: Frail elderly must receive both nutritional as well as
exercise intervention for the alleviation of their frail status. Exercise
intervention in the form of nordic walking can be an attractive op-
tion for significant functional improvement in frail older patients.

Introduction: The aim of this study was to determine the
association of frailty with serum 25-hydroxyvitamin D in a
population-based sample of older men.
Methods: Cross-sectional analyses were performed on data from a
longitudinal study in 264 ambulatory men aged 72 to 87 years and
registered in the community of Merelbeke (Ghent, Belgium) in 1997.
Frailty status (robust vs. prefrail or frail) was assessed using the
Study of Osteoporotic Fractures (SOF) index with the components
of weight loss, inability to rise from a chair 5 times without
using arms, and reduced energy level. Serum 25-hydroxyvitamin D
was determined after extraction by radioimmunoassay. Low 25-
hydroxyvitamin D level was defined as <30 ng/ml. Logistic
regression models adjusted for age and body mass index examined
the relationship between (low) 25-hydroxyvitamin D level and
(pre)frailty.
Results: Mean age was 76.7±3.9 years. According to the SOF
index, 181 men (69%) were robust, 79 men (30%) were prefrail or
frail. Serum 25-hydroxyvitamin D concentration was significantly
associated with (pre)frailty (OR per ng/ml decrease = 1.05, 95%CI =
1.01–1.09, P = 0.009). Older men with low 25-hydroxyvitamin D
levels had 2.7 times more odds of being (pre)frail than older men
with normal 25-hydroxyvitamin D levels (OR=2.71, 95%CI = 1.38–
5.40, P = 0.005).
Key conclusions: Our findings suggest that lower serum 25-
hydroxyvitamin D levels are associated with (pre)frailty in
older men.

Nutrition plays a gender-dependent role in disability in an
elderly Sardinian population
D. Concu, G.M. Pes

Introduction: In the elderly population the disability rate is lower
in men than in women, although in the latter life expectancy in
generally higher. In Sardinia island a remarkable gender equality
in mortality has been reported (Poulain et al., 2004), but it is
not known if this also holds true for disability. We evaluated the
disability level in a sample of elderly subjects and correlated it with
lifestyle and socio-demographic variables.
Subjects and Methods: One-hundred subjects (50% men, aged
78–93) recruited in the island’s main cities. A comprehensive
assessment was carried out in each participant: ADL, IADL, Barthel
index, MMSE, Exton-Smith and Tinetti scale, km/wk and MNA. The
association of predictors with disability was performed by multiple
linear regression analysis.
Results: Among women the strongest predictors of disability,
as reflected by IADL, were MNA (p=0.0001), SPMSQ (p =0.004)
and Tinetti score (p = 0.001), whereas in males physical activity
expressed as km/wk (p =0.039), the Exton-Smith score (p = 0.0001)
and MMSE (p =0.001) were the most important predictors.
Conclusion: These results suggest that IADL disability in males
is mostly linked to cognitive and motor impairment, whereas
in women is influenced also by a concomitant malnutrition. We
suggest that physical activity is a protective factor for disability in
men, while women lacking this protective mechanism are more
vulnerable to a nutritional deficiency.

Frailty and health-related quality of life in ambulatory older
men

Introduction: The aim of this study was to investigate the
relationship between frailty status and health-related quality of
life in a population-based sample of ambulatory older men.
Methods: Cross-sectional analyses were performed on data from a
longitudinal study in 260 ambulatory men aged 72 to 87 years and
registered in the community of Merelbeke (Ghent, Belgium) in 1997.
Frailty status (robust, prefrail, frail) was assessed using the Study of
Osteoporotic Fractures (SOF) index with the components of weight
loss, inability to rise from a chair 5 times without using arms, and
reduced energy level. Health-related quality of life was assessed
using the eight domains of the Short Form-36 questionnaire.
Subjects in the lowest quartile of the distribution were classified
as having ‘poor’ status for each domain. Logistic regression models
adjusted for age examined the relationship between frailty status
and poor status on the Short Form-36 domains.
Results: Mean age was 76.7±3.9 years. According to the SOF index,
181 men (69%) were robust, 69 men (26%) were prefrail, and 10 men
(4%) were frail. The distribution of the Short Form-36 domain scores
differed significantly across frailty statuses (Table 1). Prefrailty and
frailty were significantly associated with increased prevalence of
poor status for all 8 Short-Form 36 domains.
Key conclusions: Our findings suggest that both prefrailty and
frailty are associated with poorer health-related quality of life in
older men, independent of age.

Introduction: Contactless monitoring is increasingly used to
enhance qualitative and cost-effective care for older persons.
Succesful implementation of this technology, depends on its
acceptance by older people. The purpose was to explore attitudes
and perceptions of adults aged ≥60 years towards contactless
monitoring.
Methods: A questionnaire was developed, validated and used
in a cross-sectional survey with a convenience sample (n =245).
Descriptive and bivariate statistics were used for data analysis.
