Of the handful of national studies tracking trends in adolescent substance use in the United States, only the Health Behavior in School-Aged Children (HBSC) study collects data from 6th through 10th graders. The purpose of this study was to examine trends from 1998 to 2010 (four time points) in the prevalence of tobacco, alcohol, and marijuana use among 6th through 10th graders. Differences in trends by grade, gender, and race/ethnicity were examined for each substance use behavior, with a primary focus on trends for sixth and seventh graders. Overall, there were significant declines in tobacco, alcohol, and marijuana use from 1998 to 2010. The declines were largest for the younger grades, which suggest promise for future declines among high school students as these cohorts age into high school.
在美国，为数不多的追踪青少年物质使用趋势的全国性研究中，只有学龄儿童健康行为（HBSC）研究收集了6至10年级学生的数据。本研究的目的是调查1998年至2010年（四个时间点）6至10年级学生中烟草、酒精和大麻使用流行率的趋势。针对每种物质使用行为，研究了按年级、性别和种族/族裔划分的趋势差异，主要关注六年级和七年级学生的趋势。总体而言，1998年至2010年期间，烟草、酒精和大麻的使用显著下降。低年级学生的降幅最大，这表明随着这些学生群体升入高中，未来高中生中的使用量有望进一步下降。
