Examine patterns of progression in substance use among Hispanic youth 13 to 17 years of age from two longitudinally representative studies.
Patterns of substance use among youth in Puerto Rico were examined using a longitudinal study (n=663) of adolescents living on the island. The National Longitudinal Study of Youth was used to examine patterns of substance use among Hispanics living in the United States (n=1,445). Latent transition analysis was used to estimate the probability of membership in each stage of substance use and incidence of transitions between different substance use stages over time.
Six stages best described the heterogeneity in substance use among youth in Puerto Rico. Five stages were sufficient to describe patterns of substance use among youth in the United States. Youth living in Puerto Rico reported lower rates of smoking and illicit drug use, but higher rates of alcohol use, when compared with rates among Hispanics in the United States.
Similar patterns of substance use were identified for Hispanic youth living in the United States and youth living in Puerto Rico.
通过两项具有纵向代表性的研究，考察13至17岁西班牙裔青少年物质使用的进展模式。
利用一项对波多黎各岛上青少年进行的纵向研究（n = 663），考察波多黎各青少年的物质使用模式。利用全国青少年纵向研究来考察居住在美国的西班牙裔青少年的物质使用模式（n = 1445）。采用潜在转变分析来估计处于物质使用各阶段的概率以及不同物质使用阶段随时间转变的发生率。
六个阶段最能描述波多黎各青少年物质使用的异质性。五个阶段足以描述美国青少年的物质使用模式。与美国西班牙裔的比率相比，居住在波多黎各的青少年报告的吸烟和非法药物使用率较低，但酒精使用率较高。
居住在美国的西班牙裔青少年和居住在波多黎各的青少年具有相似的物质使用模式。
