Abstract

Background: It is unclear if improving diet quality after midlife could reduce the risk of physical frailty at late life. We aimed to associate changes in diet quality after midlife with physical frailty at late life.

Methods: Diet quality in 12,580 participants from the Singapore Chinese Health Study was assessed with the Dietary Approaches to Stop Hypertension (DASH) scores at baseline (1993-1998; mean age 53 years) and follow-up 3 (2014-2016; mean age 73 years). Physical frailty was assessed using the modified Cardiovascular Health Study phenotype at follow-up 3. Multivariable logistic regressions examined associations between DASH scores and physical frailty.

Results: Comparing participants in extreme quartiles of DASH scores, the odds ratios (OR) [95% confidence interval (CI)] for physical frailty were 0.85 (0.73,0.99) at baseline and 0.49 (0.41, 0.58) at follow-up 3. Compared to participants with consistently low DASH scores, participants with consistently high scores (OR 0.74, 95% CI: 0.59, 0.94) and those with > 10% increase in scores (OR 0.78, 95% CI: 0.64, 0.95) had lower odds of frailty. Compared to those in the lowest DASH tertiles at both time-points, significantly lower odds of physical frailty were observed in those who were in the highest DASH tertiles at both time points [0.59 (0.48, 0.73)], and in those who improved their scores from the lowest [0.68 (0.51, 0.91)] or second tertile at baseline [0.61 (0.48, 0.76)] to the highest tertile at follow-up 3.

Conclusions: Maintaining a high diet quality or a substantial improvement in diet quality after midlife could lower the risk of physical frailty at late life.

中国成年人队列中从中年到晚年的饮食质量及其与晚年身体虚弱的关系。

背景：目前尚不清楚中年以后饮食质量的改善能否降低晚年身体虚弱的风险。我们的目的是将中年后饮食质量的变化与晚年身体虚弱联系起来：方法：在基线（1993-1998 年；平均年龄 53 岁）和随访 3（2014-2016 年；平均年龄 73 岁）期间，采用饮食疗法阻止高血压（DASH）评分对新加坡华人健康研究（Singapore Chinese Health Study）的 12,580 名参与者的饮食质量进行了评估。在随访 3 期，采用改良的心血管健康研究表型评估身体虚弱程度。多变量逻辑回归检验了DASH评分与身体虚弱之间的关联：结果：与 DASH 评分处于极端四分位数的参与者相比，基线时身体虚弱的几率比（OR）[95% 置信区间（CI）]为 0.85（0.73,0.99），随访 3 时为 0.49（0.41,0.58）。与DASH评分一直较低的参与者相比，评分一直较高的参与者（OR 0.74，95% CI：0.59，0.94）和评分增加>10%的参与者（OR 0.78，95% CI：0.64，0.95）出现虚弱的几率较低。与在两个时间点均处于最低DASH三分位数的人群相比，在两个时间点均处于最高DASH三分位数的人群[0.59 (0.48, 0.73)]，以及在随访3时得分从基线时的最低[0.68 (0.51, 0.91)]或第二三分位数[0.61 (0.48, 0.76)]提高到最高三分位数的人群中，身体虚弱的几率明显较低：结论：保持较高的饮食质量或在中年后大幅提高饮食质量可降低晚年身体虚弱的风险。

期刊介绍： Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
