Intention for weight change stats

[Guest guest]

Hi All,

The below paper appears to document how many older adults lose, gain or maintain

stable weight and is pdf-avaialble.

Intention to lose weight has always been a concern to how to evaluate

weight/calorie

intake changes with regard to their justifying the CR life.

In addition, what fraction of the methods used to induce weight change involve

CR?

These issues are addressed in the below paper, for which excerpts are shown.

Rubin, and Anne B Newman

Short-term weight changes in community-dwelling older adults: the Health, Aging,

and

Body Composition Weight Change Substudy

Am J Clin Nutr 2005 82: 644-650.

Background: ... Unintentional weight loss may be more likely to continue than

intentional weight loss. ...

Design: A total of 522 older adults with either a 5% weight gain (n = 116) or a

5%

weight loss (n = 171) in the previous year were compared with a random sample of

weight-stable older adults (<5% weight loss or gain, n = 235) at the fourth

annual

visit of the ongoing Health ABC Study. ... assessed by an interview. ...

Results: Compared with the weight-stable participants, the participants who had

lost

or gained weight at the substudy baseline were more likely to have subsequent

weight

changes. The direction of the subsequent weight change, however, was more likely

toward either maintenance of or recovery from the previous weight change. Only

4% of

the participants who gained weight and 11% of those who lost weight continued to

gain or lose weight, respectively. Continued weight loss was more common in the

participants with unintentional weight loss than in those with intentional

weight

loss, but the difference was not significant.

....................................

Methods Proportion of responses n (%)

....................................

Reduced food intake 44 (33.1)

Reduced fat intake 24 (18.1)

Increased exercise 18 (13.5)

Use of fat- or calorie-modified foods 18 (12.8)

Consulted with health professionals 4 (3.0)

Decreased alcohol intake 3 (2.3)

Participants who were classified as having intentional weight loss were asked to

select multiple methods they used to lose weight from a list provided in a

questionnaire.
