Predictors of calcium intake patterns: a longitudinal analysis. Abstract Text:

Susan J Blalock,

OBJECTIVE: The study was guided by the precaution adoption process model; the author examined factors associated with (a) stage of change with respect to calcium intake at 4 time points and (b) calcium intake patterns across time. DESIGN: Data were collected by mailed questionnaire at baseline and at 3 follow-up assessments over 1 year. MAIN OUTCOME MEASURES: The primary outcome measures were calcium intake, stage of change with respect to calcium intake, and pattern of calcium intake across follow-up. Three patterns were identified: successful maintenance (adequate calcium intake at all 3 follow-ups), vacillation (adequate calcium consumption at 1 or 2 follow-ups), and inertia (inadequate calcium consumption at all 3 follow-ups). RESULTS: Five hundred six women completed baseline questionnaires, and 346 completed 3 follow-up assessments. Even after baseline stage of change was controlled for, longitudinal analyses revealed 3 variables that predicted different patterns of behavior across time. Isolated instances of adequate calcium intake were predicted by higher levels of knowledge and perceived benefits, whereas long-term maintenance was predicted by lower levels of perceived difficulty. CONCLUSION: These findings provide support for a central premise of the model, that different factors are important at different points in the behavior change process.
