OBJECTIVE
To examine whether changes in diet quality predict changes in central adiposity among postmenopausal women.

METHODS
At baseline and 3-year follow-up, Women's Health Initiative Observational Study participants completed food frequency questionnaires, and waist circumference was measured (WC, n = 67,175). In a subset, trunk fat was measured via dual-energy X-ray absorptiometry (DXA, n = 4,254). Using multivariable linear regression, 3-year changes in dietary patterns (Healthy Eating Index-2010, Alternate Healthy Eating Index-2010, Alternate Mediterranean Diet, and Dietary Approaches to Stop Hypertension) were examined as predictors of concurrent changes in WC and, secondarily, DXA.

RESULTS
Mean (SD) age and 3-year changes in weight and WC were 63 (7) years, 0.52 (4.26) kg, and 0.94 (6.65) cm. A 10% increase in any dietary pattern score, representing improved diet quality, was associated with 0.07 to 0.43 cm smaller increase in WC over 3 years (all P < 0.05). After adjusting for weight change, associations attenuated to 0.02 to 0.10 cm but remained statistically significant for all patterns except Alternate Mediterranean Diet. Results were similar for DXA trunk fat.

CONCLUSIONS
Three-year improvements in diet quality are modestly protective against gain in WC and partially explained by lesser weight gain. Achieving and maintaining a healthful diet after menopause may protect against gains in central adiposity.
