背景资料：以前的研究描述了美国大麻使用的趋势，并检查了年龄阶段队列（APC）的影响，发现1945年以后出生的队列中终身使用的增加。然而，没有研究利用当前消费的数据在多个横截面调查，估计这些factors.Methods：包括人口因素的logistic回归模型，估计在1984年和2000年之间进行的四个美国国家酒精调查（NAS）。在过去一年的大麻使用的趋势也evaluated.Results：大麻使用下降，在研究期间从10%到7.2%的人口。下降的主要是男子，这导致了一定程度的性别趋同，特别是对18-25岁的人而言。发现年龄、时期和队列的显著影响，从20岁出头到40岁，使用率急剧下降。1945年以后出生的所有男性队列和1945年和1960年之间出生的女性队列显示患病率升高相比，早期cohols.Conclusions：趋势结果从NAS不同于其他调查，并表明过去一年大麻的使用和性别趋同的患病率下降。APC结果证实了过去的年龄效应和1945年之前和之后出生的人群之间的队列差异的研究结果。海洋生物的使用带来了许多测量困难，需要进一步研究以了解不同调查之间的差异。(c)2006爱思唯尔爱尔兰有限公司保留所有权利。
Background: Previous studies have described trends in marijuana use in the US and examined age-period-cohort (APC) effects finding increased lifetime use among cohorts born after 1945. However, no studies have utilized data on current consumption in multiple cross-sectional surveys to estimate these factors.Methods: Age-period-cohort models including demographic factors are estimated using logistic regressions in four US National Alcohol Surveys (NAS) conducted between 1984 and 2000. Trends in past year marijuana use are also evaluated.Results: Marijuana use declined over the study period from 10% to 7.2% of the population. Declines were mainly seen among men, resulting in a degree of gender convergence, particularly for those aged 18-25. Significant effects of age, period and cohort were found, with steep declines in use by age from the early 20s to the 40s. All male cohorts born after 1945 and female cohorts born between 1945 and 1960 showed elevated prevalence compared to earlier cohorts.Conclusions: Trend results from the NAS differ from those in other surveys and indicate decreased prevalence of past year marijuana use and gender convergence. APC results confirm past findings of age effects and cohort differences between those born before and after 1945. Marijuana use presents many measurement difficulties and future research to understand differences across surveys is needed. (c) 2006 Elsevier Ireland Ltd. All rights reserved.
