Using measures of behaviors shown to predict low-fat intake in previous research, this study examined whether the behaviors would predict low-fat intake among urban African American adolescents. Recruited through youth services agencies in Philadelphia, Pa, participants were 399 African American adolescents (67% female subjects) with a mean age of 13.09 years (range, 10-15 years). Fat-related dietary behaviors were measured using items that were adapted from the Food Habits Questionnaire. Fat intake was measured using the Block Fat Screener. Spearman correlations examined the relationships between fat-related dietary behaviors and fat intake. Seven behaviors were significantly associated with low-fat intake: had chicken that was baked or broiled instead of fried; ordered pasta or pizza served without meat sauce or meat toppings; had a vegetarian dinner; used low-calorie instead of regular salad dressing; ate at least 2 vegetables (not green salad) at dinner; ate bread, rolls, or muffins without butter or margarine; and avoided foods that were fried in oil, shortening, or lard. Using multiple regression, fat intake was regressed on the linear combination of demographic variables and these fat-related dietary behaviors. The regression equation accounted for 17% of the variance in fat intake (adjusted R(2) = 0.13). Fat avoidance (ate bread, rolls, or muffins without butter or margarine) and replacement (ordered pasta or pizza served without meat sauce or meat toppings) behaviors were significant predictors of low-fat intake. Dietary interventions to lower fat intake among urban African American adolescents should promote the adoption of these behaviors.
本研究运用先前研究中已证实可预测低脂肪摄入量的行为指标,来检验这些行为能否预测城市非裔美国青少年的低脂肪摄入量。通过宾夕法尼亚州费城的青年服务机构招募参与者,共有399名非裔美国青少年(67%为女性),平均年龄为13.09岁(年龄范围为10 - 15岁)。与脂肪相关的饮食行为采用改编自《饮食习惯问卷》的条目进行测量。脂肪摄入量使用《Block脂肪筛选器》进行测量。斯皮尔曼相关性分析检验了与脂肪相关的饮食行为和脂肪摄入量之间的关系。七种行为与低脂肪摄入量显著相关:食用烘焙或烤制而非油炸的鸡肉;点没有肉酱或肉类配料的意大利面或披萨;吃素食晚餐;使用低热量而非常规的沙拉酱;晚餐至少吃两种蔬菜(非蔬菜沙拉);吃不加黄油或人造黄油的面包、面包卷或松饼;避免食用用植物油、起酥油或猪油油炸的食物。使用多元回归分析,将脂肪摄入量对人口统计学变量和这些与脂肪相关的饮食行为的线性组合进行回归。回归方程解释了脂肪摄入量方差的17%(调整后R² = 0.13)。避免食用脂肪(吃不加黄油或人造黄油的面包、面包卷或松饼)和替代行为(点没有肉酱或肉类配料的意大利面或披萨)是低脂肪摄入量的显著预测因素。针对城市非裔美国青少年降低脂肪摄入量的饮食干预措施应促进这些行为的养成。
