Abstract
PURPOSE: Obesity and poor diet quality (DQ) are associated with increased risk of morbidity/mortality among breast cancer survivors. This study explored DQ changes during a weight loss maintenance intervention in a cohort of rural female breast cancer survivors (n = 131) who lost ≥ 5% body weight in a weight loss intervention. Previous analyses demonstrated significant DQ improvements during weight loss. METHODS: DQ was calculated using the alternate Healthy Eating Index (aHEI)-2010. Differences in scores across time for the cohort and between those that maintained weight loss within 5% (low regainers) and those that regained > 5% (high regainers) were analyzed by linear mixed models. RESULTS: Significant improvements in aHEI total score were observed from baseline (M = 52.3 ± 11) to 6 months (M = 60.7 ± 8; p < 0.001); these improvements were sustained from 6 to 18 months (M = 58.4 ± 11; p = 0.16). Total aHEI-2010 score at 18 months was higher in low regainers, compared with high regainers (60.7 vs. 56.0, p = 0.03), with healthier component scores for red meat (p = 0.01) and fruit (p = 0.04), and a trend for a healthier score for sugar-sweetened beverages (p = 0.08). CONCLUSIONS: Overall DQ improvements made during a weight loss intervention for rural breast cancer survivors were sustained during a weight loss maintenance intervention; this intervention was effective in helping low regainers maintain healthier scores in fruit, red meat, and sugar-sweetened beverage components. IMPLICATIONS FOR CANCER SURVIVORS: Maintaining higher DQ may help breast cancer survivors maintain weight loss, thereby reducing risk of breast cancer recurrence and premature death from comorbidities.
