Abstract

INTRODUCTION

Reliable dietary information is crucial for measuring the habitual diet of healthy participants and patients with dyslipidaemia and/or coronary heart disease (CHD). Even so, methods are often complicated and time-consuming for everyone involved. We aimed to validate the new food frequency questionnaire (FFQ) named HeartDiet by comparing it to a validated 198-item FFQ and biomarkers.

METHODS

Healthy local participants (n = 100) and participants with CHD from Aalborg University Hospital (n = 100) randomly completed HeartDiet and the 198-item FFQ. Biomarkers were analysed in a random sample of 50 healthy participants. Scatter plots and Spearman's rank correlation coefficient were used for statistics.

RESULTS

We found a highly significant statistical correla-tion between the intake of fruit (ρ = 0.70; 95% confidence interval (CI): 0.62-0.76), vegetables (ρ = 0.54; 95% CI: 0.44-0.64), fish (ρ = 0.75; 95% CI: 0.68-0.81) and saturated fatty acids (ρ = -0.51; 95% CI:-0.61--0.40) measured by the HeartDiet and the 198-item FFQ. Also, correlations between the HeartDiet and serum β-carotene and serum n-3 polyunsaturated fatty acids were statistically significant (fruit and vegetables: ρ = 0.59; 95% CI: 0.37-0.74, and fish: ρ = 0.45; 95% CI: 0.19-0.65).

CONCLUSIONS

HeartDiet is well aligned with results from a semi-quantitative FFQ and biomarkers, and it is a practical, easy and quick-to-use tool to describe and monitor if a diet is heart-healthy or not.

摘要

引言

可靠的饮食信息对于衡量健康参与者以及血脂异常和/或冠心病（CHD）患者的习惯饮食至关重要。即便如此，对于所有相关人员而言，方法往往复杂且耗时。我们旨在通过将名为HeartDiet的新型食物频率问卷（FFQ）与经过验证的198项FFQ及生物标志物进行比较，来验证该问卷。

方法

健康的当地参与者（n = 100）和奥尔堡大学医院的冠心病患者（n = 100）随机完成HeartDiet和198项FFQ。对50名健康参与者的随机样本进行生物标志物分析。使用散点图和斯皮尔曼等级相关系数进行统计。

结果

我们发现，通过HeartDiet和198项FFQ测得的水果摄入量（ρ = 0.70；95%置信区间（CI）：0.62 - 0.76）、蔬菜摄入量（ρ = 0.54；95% CI：0.44 - 0.64）、鱼类摄入量（ρ = 0.75；95% CI：0.68 - 0.81）和饱和脂肪酸摄入量（ρ = -0.51；95% CI：-0.61 - -0.40）之间存在高度显著的统计相关性。此外，HeartDiet与血清β - 胡萝卜素和血清n - 3多不饱和脂肪酸之间的相关性也具有统计学意义（水果和蔬菜：ρ = 0.59；95% CI：0.37 - 0.74，鱼类：ρ = 0.45；95% CI：0.19 - 0.65）。
