Hypertension and cardiovascular disease burden are rising rapidly in Nigeria. This trend is partly attributed to a transition from healthy to unhealthy dietary patterns. However, health care professionals lack a dietary screening tool to assess patient dietary intake and offer personalized dietary advice.
We aimed to develop and validate a food frequency questionnaire (FFQ) that can quickly and accurately assess regional dietary intake for use by health care professionals in a hospital setting in Port Harcourt, Nigeria.
We recruited 58 patients from a single hospital in Nigeria. The FFQ was administered at baseline and again after 3 wk. To evaluate the validity of the FFQ, we used 3 repeated and nonconsecutive 24-h dietary recalls (24DR) as a reference method. Spearman rank correlations, Wilcoxon signed-rank tests, cross-classification, intraclass correlation coefficients (ICCs), and Bland-Altman analysis were performed in R software version 4.3.1 to assess the relative validity and reproducibility.
The mean correlation coefficient ( ) between the FFQ and 24DR was 0.60 ( < 0.05), and ranged from 0.20 to 0.78. The Wilcoxon signed-rank tests indicated no significant differences in the 19 food groups queried ( > 0.05), except for fats and oils ( < 0.05). The exact agreement for classifying individuals into quartiles ranged from 17% for salt to 88% for processed meats and alcoholic drinks, with 90% of individuals classified into the same or neighboring quartile. Additionally, the Bland-Altman analysis demonstrated acceptable agreement, with >96% of observations within the acceptable limits of agreement for all food groups. For reproducibility, the ICC ranged from 0.31 for stew to 0.98 for fruit, with an mean ICC of 0.77 between the FFQs delivered 2 wk apart.
Our results support the use of the FFQ as a valid and reliable tool for ranking intakes of certain food groups among patients in a hospital setting in Nigeria.The trial was registered at clinicaltrials.gov as NCT05973760.
在尼日利亚，高血压和心血管疾病负担正在迅速上升。这种趋势部分归因于从健康饮食模式向不健康饮食模式的转变。然而，医疗保健专业人员缺乏一种饮食筛查工具来评估患者的饮食摄入量并提供个性化的饮食建议。
我们旨在开发并验证一种食物频率问卷（FFQ），该问卷能够快速、准确地评估尼日利亚哈科特港一家医院环境中医疗保健专业人员使用的区域饮食摄入量。
我们从尼日利亚的一家单一医院招募了58名患者。FFQ在基线时进行发放，并在3周后再次发放。为了评估FFQ的有效性，我们使用3次重复且不连续的24小时饮食回顾（24DR）作为参考方法。在R软件版本4.3.1中进行Spearman等级相关性分析、Wilcoxon符号秩检验、交叉分类、组内相关系数（ICC）分析以及Bland - Altman分析，以评估相对有效性和可重复性。
FFQ与24DR之间的平均相关系数（ ）为0.60（<0.05），范围从0.20至0.78。Wilcoxon符号秩检验表明，除了油脂类（<0.05）外，所询问的19个食物组中没有显著差异（>0.05）。将个体分类到四分位数的精确一致性范围从盐的17%到加工肉类和酒精饮料的88%，90%的个体被分类到相同或相邻的四分位数。此外，Bland - Altman分析显示出可接受的一致性，所有食物组中超过96%的观察值在可接受的一致性限度内。对于可重复性，ICC范围从炖菜的0.31到水果的0.98，相隔2周发放的FFQ之间的平均ICC为0.77。
我们的结果支持将FFQ用作在尼日利亚医院环境中对患者某些食物组摄入量进行排名的有效且可靠的工具。该试验在clinicaltrials.gov上注册为NCT05973760。
