ABSTRACT: Individuals
successful at weight loss maintenance (WTLM) utilize similar behaviors but in
varying amounts and combinations. Research identifying characteristics which
predict WTLM success could be used to develop effective WTLM treatment
programs. The purpose of this retrospective analysis was to determine
behavioral (e.g., self monitoring of dietary intake) and biological factors
(e.g., sex) which may influence WTLM success. Methods: In a previously
conducted 12-month WTLM study, weight-reduced middle-aged and older men and
women (n = 39) were assigned behavioral goals and asked to daily self-monitor
body weight, fruit and vegetable intake, water consumption, and physical
activity. This investigation utilized a crisp set qualitative comparative
analysis (QCA) to characterize individuals’ weight changes and behaviors. Sex
difference in clinically significant weight loss (WL) (≥5% WL) at 12 months
was investigated, and growth curve models estimated interaction effects between
sex and WTLM predictors. Results: QCA findings suggest patterns of weight
change during the initial three months of WTLM treatment may dictate 12-month
weight outcomes. No sex difference was found in clinically significant WL or in
the interaction of sex and behaviors on weight change. Conclusions: WTLM
treatments should provide more intensive support during transition from WL to
WTLM, particularly during the first three months.
