OBJECTIVES
This paper describes the Northwest Lipid Research Clinic Fat Intake Scale, a brief dietary questionnaire to screen and monitor dietary intake related to plasma cholesterol levels.
METHODS
The 12-item instrument assesses intake of foods high in fat, saturated fat, and cholesterol. Test-retest reliability was assessed on 194 men and 116 women with high cholesterol prior to a dietary intervention study. To measure validity and responsiveness to dietary change, scores were compared with 4-day food records before and after diet education classes.
RESULTS
Test-retest correlation coefficients were .88 for men and .90 for women (2 weeks between scores). Scores for men and women were correlated with nutrients shown by food records at baseline (.47 and .54, total fat; .50 and .51, saturated fat) and 18 months postintervention (.52 and .58, total fat; .56 and .64, saturated fat; all Ps < .001). Mean scores decreased from about 30 to 23 (P < .001, paired t test).
CONCLUSIONS
The Fat Intake Scale, a qualitative instrument, has acceptable reliability and validity for estimating the level of cholesterol-related diet components and reflects dietary modification. The format of the instrument also lends itself to patient education and goal setting.
目的
本文介绍了西北脂质研究诊所脂肪摄入量表，这是一种简短的饮食调查问卷，用于筛查和监测与血浆胆固醇水平相关的饮食摄入情况。
方法
该12项工具评估高脂肪、饱和脂肪和胆固醇食物的摄入量。在一项饮食干预研究之前，对194名高胆固醇男性和116名高胆固醇女性进行了重测信度评估。为了衡量有效性和对饮食变化的反应性，将得分与饮食教育课程前后的4天食物记录进行了比较。
结果
男性的重测相关系数为0.88，女性为0.90（两次得分间隔2周）。男性和女性的得分与基线时食物记录显示的营养素相关（总脂肪分别为0.47和0.54；饱和脂肪分别为0.50和0.51）以及干预后18个月（总脂肪分别为0.52和0.58；饱和脂肪分别为0.56和0.64；所有P值均<0.001）。平均得分从约30降至23（P<0.001，配对t检验）。
结论
脂肪摄入量表作为一种定性工具，在估计与胆固醇相关的饮食成分水平方面具有可接受的信度和效度，并能反映饮食变化。该工具的形式也有助于患者教育和目标设定。
