Abstract

BACKGROUND:

Depressive symptoms can lower adherence and change in dietary studies. Behavioral activation may reduce these effects.

PURPOSE:

This study aims to assess relationships among depressive symptoms on adherence and dietary change in the Women's Healthy Eating and Living (WHEL) Study

METHODS:

Secondary analyses from the WHEL Study, which achieved major dietary change in breast cancer survivors (N = 2817), were conducted. Logistic regressions were undertaken of baseline depressive symptoms (six-item Center for Epidemiologic Studies Depression Scale (CES-D)) with (1) completion of 1- and 4-year study assessments and (2) validated change in dietary behavior in the intervention group.

RESULTS:

In the comparison group (vs. intervention), depressive symptoms lowered completion of dietary recalls and clinic visits [4 years: odds ratio (OR) = 2.0; 95 % confidence interval (CI) = 1.4-3.0]. The behaviorally oriented intervention achieved major change in those furthest from study targets, although changes were lower in those with depressive symptoms: fruit/vegetable (+37.2 %), fiber (+49.0 %), and fat (-22.4 %).

CONCLUSIONS:

Behavioral activation in dietary change interventions can overcome the impact of depressive symptoms.
