Issue addressed The present study investigated the association between diet quality, measured using the Australian Recommended Food Score (ARFS), and 6-year risk of becoming overweight or obese in mid-age women from the Australian Longitudinal Study of Women's Health (ALSWH). Methods Women (n=1107) aged 47.6-55.8 years who were a healthy weight (body mass index (BMI) between ≤18.5 and <25.0kgm(-2)) at baseline and who reported valid total energy intakes were included in the study. BMI was calculated from self-reported data in 2001 and 2007. ARFS scores were calculated from data collected using the Dietary Questionnaire for Epidemiological Studies Version 2. Logistic regression was used to examine the relationship between ARFS score as a continuous variable and risk of becoming overweight or obese. Results The 6-year incidence of overweight and obesity was 18.5% and 1.1%, respectively. The mean (± s.d.) ARFS (maximum possible 74) among those who remained within the healthy weight range and those who became overweight or obese at follow-up was 35.3±8.1 and 34.3±8.8, respectively. There was no relationship between baseline ARFS and risk of becoming overweight or obese over 6 years. Women who were smokers were more likely to become overweight or obese (odds ratio 1.5; 95% confidence interval 1.11-2.09; P=0.008). Conclusions Poor diet quality was common among mid-age women of a healthy weight in the ALSWH. Higher diet quality was not associated with the risk of overweight or obesity after 6 years, yet smoking status was. So what? Better diet quality alone will not achieve maintenance of a healthy weight, but should be encouraged to improve other health outcomes.
研究问题 本研究利用澳大利亚推荐食物评分（ARFS）来衡量饮食质量，并探讨其与澳大利亚女性健康纵向研究（ALSWH）中中年女性6年超重或肥胖风险之间的关联。方法 纳入1107名年龄在47.6 - 55.8岁之间、基线时体重正常（体重指数（BMI）在≤18.5至<25.0kg/m²之间）且报告了有效总能量摄入量的女性。BMI根据2001年和2007年的自我报告数据计算得出。ARFS评分根据使用流行病学研究膳食问卷第2版收集的数据计算得出。采用逻辑回归分析来检验作为连续变量的ARFS评分与超重或肥胖风险之间的关系。结果 超重和肥胖的6年发病率分别为18.5%和1.1%。在随访期间体重仍保持在健康范围内的女性以及超重或肥胖的女性中，ARFS的平均（±标准差）得分（最高可能为74分）分别为35.3±8.1和34.3±8.8。基线ARFS与6年内超重或肥胖风险之间没有关系。吸烟者更有可能超重或肥胖（优势比1.5；95%置信区间1.11 - 2.09；P = 0.008）。结论 在ALSWH中，体重正常的中年女性饮食质量普遍较差。较高的饮食质量与6年后超重或肥胖风险无关，但吸烟状况与之有关。那又如何？仅靠改善饮食质量并不能维持健康体重，但仍应鼓励改善饮食质量以提高其他健康指标。
