摘要目的
本研究检查了个体和集体因素作为全球饮食质量（DQ）变化的预测因子。MethodsSubjects为373名年龄在68-82岁的老年人（57%为女性），招募（T1）到NuAge队列研究中，并随访三年。研究资料以问卷调查、体能测验及人体测量等方式收集。在T1和T4使用三个非连续的24小时饮食回忆（24 HR）和DQ（加拿大健康饮食指数）评估饮食，并计算24 HR的平均值。DQ在三年内的变化被确定为“DQT 4-DQT 1”。基线（T1）的措施显着相关的DQ在T1进入后向逐步线性回归分析沿着选定的理论结构和控制基线DQ，以确定DQ的变化超过3年的预测因子。
结果在男性中，教育（p = .009）和饥饿感（p = .01）是DQ随时间变化的正预测因子，而T1时的DQ（p < .0001）、认知（p = .003）和社交网络（p = .019）是负预测因子（校正R2 = 30.4%）。最后，在妇女中，饮食知识（p = 0.044）是DQ变化的积极预测因子，而DQ在T1（p <0.0001）和社会网络（p = 0.033）是DQ变化的消极预测因子超过3年（调整R2 = 24.1%）。
AbstractPurpose
This study examined individual and collective factors as predictors of change in global diet quality (DQ).MethodsSubjects were 373 older adults (57 % female) aged 68–82 years at recruitment (T1) into the NuAge Cohort Study, and followed for three years. Data were collected by questionnaires, physical performance tests and anthropometric measurements. Diet was assessed at T1 and T4 using three non-consecutive 24-h diet recalls (24HR) and DQ (Canadian Healthy Eating Index), and was computed on the means of the 24HR. DQ change over three years was determined as “DQT4-DQT1”. Baseline (T1) measures significantly correlated with DQ at T1 were entered into backward stepwise linear regression analyses along with selected theoretical constructs and controlled for baseline DQ to determine predictors of change in DQ over 3 years.
ResultsAmong men, education (p = .009) and sensations of hunger (p = .01) were positive predictors of DQ change over time, while DQ at T1 (p < .0001), cognition (p = .003) and social network (p = .019) were negative predictors (adjusted R2 = 30.4 %). Finally, among women, diet knowledge (p = .044) was a positive predictor of DQ change, while DQ at T1 (p < .0001) and social network (p = .033) were negative predictors of DQ change over 3 years (adjusted R2 = 24.1 %).ConclusionsThese results can inform dietary intervention programmes targeting gender-specific determinants of diet quality in older adults.
