Behavioural correlates of successful weight reduction over 3 y. Results from the Lean Habits Study.

OBJECTIVE

To examine behavioural characteristics of subjects with successful long-term weight reduction.

DESIGN

Prospective cohort study with 3 y follow-up.

SETTING

Multicentre study of participants of a commercial weight-reduction programme (BCM-Programme).

SUBJECTS

Until February 2000, 6857 voluntary study participants were included. Analyses are based on 1247 subjects with complete 3 y data.

INTERVENTIONS

Open-group dietary and behavioural counselling with initial meal substitutions.

RESULTS

Subjects show a number of significant behavioural improvements, for example, choice of low-fat food, flexible control of eating behaviour and coping with stress. Subjects who maintain these changes by the end of the first year have a higher probability of successful weight reduction after 3 y.

CONCLUSIONS

Successful weight maintenance is associated with more pronounced improvements of health behaviours after 1 y. The likelihood of success increases with the number of behavioural patterns which are involved in the process of change.
