Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Nutrition is regarded as an important etiologic factor in the development of frailty in older adults. To date the relation between nutrition and frailty is only poorly described.

Thus, it is the purpose of this study to investigate the association between different nutrition characteristics and frailty in older community-living persons.

206 volunteers aged 75 years or older were included in this cross-sectional study. Nutritional assessment included the Mini-Nutritional Assessment (MNA), a food-frequency questionnaire and a standardised three-day dietary record. Intake of energy and nutrients was calculated using the German nutrient database BLS II.2. Dietary patterns were described by different dietary scores. Frailty was defined according to Fried et al. based on the following criteria: weight loss, exhaustion, grip strength, walking speed and physical activity. In addition several standardised tests were performed to characterise physical performance (Timed Up & Go, repeated chair stands, balance tests).

The association between nutritional aspects and physical performance is evaluated in an explorative manner.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Frailty (according to Fried et al.)
Time Frame: 1 day

Frailty is defined as the presence of at least 3 of the following criteria:

  • self-reported weight loss of more than 4.5 kg in the last year
  • exhaustion (self-reported feeling that everything was an effort or one could not get "going" > 2 times a week)
  • low grip strength (men ≤ 29-32 kg, women ≤ 17-21 kg depending on BMI),
  • low walking speed (> 6-7 sec/ 4.57 m, depending on gender and height)
  • low physical activity (men < 383 kcal/ week, women < 270 kcal/ week)
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Impaired physical performance (according to Guralnik et al.)
Time Frame: 1 day

Impaired physical performance is definded as less than 9 points in the Short Physical Performance Battery (SPPB).

Three physical performance tests (balance, walking speed and chair-rise) are performed in a standardised manner and rated with 0-4 points each. SPPB is the sum score of these three test resuslts with a maximum of 12 points indicating the best physical performance.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2009

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
