Data are limited regarding the prevalence of substance use among adolescents in rural and ethnically diverse communities. This study examined rates and sociodemographic correlates of lifetime substance use among adolescents in Mississippi, a rural state that is the poorest in the country (21.3% poverty rate) and has the largest proportion of African Americans per capita (36.3%).
Participants in this cross-sectional study were 6349 adolescents (6th through 12th grade) who reported on lifetime tobacco, alcohol, marijuana, cocaine, inhalant, hallucinogen, and methamphetamine use.
Lifetime smoking (10.2% to 44.5%), alcohol (23.2% to 72.0%), and marijuana use (7.9% to 39.2%) increased steadily when comparing students in 6th to 12th grade. Substances with more serious abuse potential (cocaine [6.7% to 11.1%], inhalants [12.2% to 17.9%], hallucinogens [4.4% to 12.1%], and methamphetamine [3.0% to 6.7%]) displayed more modest increases across grade. Adolescents who classified their race/ethnicity as "Other" (i.e., not white, black/African American, Asian, or Hispanic/Latino/Latina) demonstrated more than 2-fold increased likelihood of methamphetamine use (odds ratio [OR] = 2.42), and increased risk for use of any illicit substance (OR = 1.49). In general, males demonstrated an increased risk for use across substances (OR = 1.15-1.94), and higher income was associated with a decreased likelihood of illicit substance use (OR = 0.51-0.67). Living in a more populated area was associated with an increased likelihood of alcohol (OR = 1.43), marijuana (OR = 2.11), and cocaine use (OR = 2.06), and use of any illicit substance (OR = 1.54).
Mississippi adolescents reported higher rates of lifetime cocaine, inhalant, hallucinogen, and methamphetamine use across all grade levels compared with national surveys. Male gender, low income, and residence in more populated areas were associated with increased use of several substances. Findings demonstrate the need for prevention and intervention programs targeting impoverished rural and ethnically diverse communities.
关于农村和种族多样化社区青少年物质使用的流行率数据有限。本研究调查了密西西比州青少年终生物质使用的发生率和社会人口学相关性，密西西比州是一个农村州，是全国最贫穷的州（贫困率为 21.3%），人均拥有最多的非裔美国人（36.3%）。
本横断面研究的参与者为 6349 名青少年（6 至 12 年级），他们报告了终生使用烟草、酒精、大麻、可卡因、吸入剂、迷幻剂和甲基苯丙胺的情况。
比较 6 至 12 年级的学生时，终生吸烟（10.2%至 44.5%）、饮酒（23.2%至 72.0%）和大麻使用（7.9%至 39.2%）稳步增加。具有更严重滥用潜力的物质（可卡因[6.7%至 11.1%]、吸入剂[12.2%至 17.9%]、迷幻剂[4.4%至 12.1%]和甲基苯丙胺[3.0%至 6.7%]）在年级间的增幅较为适度。将种族/族裔归类为“其他”（即非白人、非黑人/非裔美国人、亚裔或西班牙裔/拉丁裔/拉丁美洲人）的青少年使用甲基苯丙胺的可能性增加了两倍以上（优势比[OR] = 2.42），并且使用任何非法物质的风险也增加（OR = 1.49）。一般来说，男性在使用各种物质方面的风险增加（OR = 1.15-1.94），较高的收入与非法物质使用的可能性降低有关（OR = 0.51-0.67）。居住在人口较多的地区与酒精（OR = 1.43）、大麻（OR = 2.11）和可卡因使用（OR = 2.06）以及任何非法物质使用（OR = 1.54）的可能性增加有关。
与全国调查相比，密西西比州青少年在所有年级报告的终生可卡因、吸入剂、迷幻剂和甲基苯丙胺使用率均较高。男性性别、低收入和居住在人口较多的地区与几种物质的使用增加有关。研究结果表明，需要针对贫困的农村和种族多样化社区制定预防和干预计划。
