Young women ( , with 1,356 women identified as plausible subsample aged 27.6£¿¡À£¿1.5 years at baseline) sampled from the Australian Longitudinal Study on Women¡¯s Health study completed food frequency questionnaires in 2003, which were used to evaluate diet quality using three indices: Australian Recommended Food Score (ARFS), Australian Diet Quality Index (Aus-DQI), and Fruit and Vegetable Index (FAVI). Weight was self-reported in 2003 and 2009. Multivariate linear regression was used to examine the association between tertiles of each diet quality index and weight change from 2003 to 2009. The ARFS and FAVI were significant predictors of 6-year weight change in this group of young women, while Aus-DQI did not predict weight change ( ). In the fully adjusted model, those who were in the top tertile of the ARFS significantly gained lower weight gain compared with the lower tertile for the plausible TEI sub-sample ( £¿kg (95% CI: £¿2.67 to £¿0.56), ). In the fully adjustment model, young women were classified in the highest FAVI tertile and gained significantly less weight than those in the lowest tertile for the plausible TEI ( £¿kg (95% CI: £¿2.4 to £¿0.3) ). In conclusion, overall diet quality measured by the ARFS and the frequency and variety of fruit and vegetable consumption may predict long-term weight gain in young women. Therefore, health promotion programs encouraging frequent consumption of a wide variety of fruits and vegetables are warranted. 1. Introduction Recently, there has been a focus on evaluating the association between the nutritional quality of dietary intake and health outcomes [1]. Several studies have reported an inverse association between higher diet quality, all-cause, and chronic disease-specific mortality [1]. Our recent systematic review demonstrated a significant association between poor diet quality and greater weight gain [2]. A recent study demonstrated, in a nationally representative sample in the United States, that younger adults have poorer diet quality when compared with both children and older adults [3]. The evidence indicates that early adulthood is a high-risk period for weight gain, especially for females [4, 5]. For example, the Australian Longitudinal Study on Women¡¯s Health (ALSWH) data shows that when young women reach their forties, they will be heavier than middle-aged women are now [5]. However, our systematic review found limited studies that have specifically examined the association between diet quality and weight %U http://www.hindawi.com/journals/jobe/2013/525161/
