Risk Factors Associated with Substance Use by Youth
Highlights

The NSDUH Report:  Youth Activities, Substance Use, and Family Income    Based on SAMHSA's 2005 National Survey on Drug Use and Health, 92.4% of youths aged 12 to 17 participated in one or more school-based, community-based, church or faith-based, or other such activities during the past year: 27.1% participated in one to three activities, 31.4% participated in four to six activities, and 33.9% participated in seven or more activities in the past year.   Youth in families of lower income were more likely not to participate in any school-based, community-based, church or faith-based or related activities; however, regardless of family income those youth who did participate had lower rates of cigarette, alcohol, or illicit drug use than those who did not participate in such activities.    The greater the number of activities, the lower the rates of past year use of cigarettes, alcohol, or illicit drugs among youth. For example, the rates of illicit drug use were 18.3% for youth who participated in no such activities, 11.9% for those with 1-3 activities, 9.4% for 4-6 activities, and 6.8% for 7 or more youth activities in the past year. 

The NSDUH Report:  Substance Use and Employment among Youths Aged 15 to 17  Based on SAMHSA's National Survey on Drug Use and Health, an estimated 33.7% of youths aged 15 to 17 were employed either part or fulltime during the past week. Employed youths were more likely than youths who were not employed to have used alcohol (35.9% vs. 24.4%), to have engaged in binge alcohol use (24.6% vs. 15.2%), and to have used an illicit drug (19.4% vs. 15.6%) during the past month. Youths working 20 or more hours per week were more likely than those working 19 or fewer hours per week to have drunk alcohol (41.1% vs. 33.8%), to have binged on alcohol (29.0% vs. 23.1%), and to have used any illicit drug (22.3% vs. 18.5%) during the past month.

The NSDUH Report:  Youth Violence and Illicit Drug Use   Based on SAMHSA's National Survey on Drug Use & Health, youths aged 12 to 17 who used an illicit drug in the past year were almost twice as likely to have engaged in a violent behavior as those who did not use an illicit drug (49.8% vs. 26.6%). Rates of past year violent behavior were higher among youths aged 13, 14, and 15 than those either younger or older. The likelihood of having engaged in violent behavior increased with the number of drugs used in the past year: 45.6% of youths who used one illicit drug engaged in violent behavior compared to 61.9% of youths who used three or more illicit drugs. 

The NSDUH Report:  Youths' Exposure to Substance Use Prevention Messages, 2003  Based on SAMHSA's National Survey on Drug Use and Health in 2003, most youths have been exposed to some kind of substance abuse prevention message - - whether having seen or heard an alcohol or drug prevention message or talked with a parent about the dangers of tobacco, alcohol, or drug use. About 84% of youths aged 12 to 17 (20.8 million) in 2003 reported having seen or heard an alcohol or drug prevention message from sources such as posters, pamphlets, radio, or TV in the past 12 months. About 59% of the youths (14.6 million) reported having talked with at least one of their parents during the past year about the dangers of tobacco, alcohol or drug use. Youth who had talked with a parent about the dangers of tobacco, alcohol, or drug use in the past year were less likely to report past month alcohol use, binge alcohol use, or illicit drug use than youths who had not talked with a parent.

The NSDUH Report:  Mother's Serious Mental Illness and Substance Use among Youths  Based on SAMHSA's National Survey on Drug Use and Health in 2002 and 2003, an annual average of 18 million women aged 18 or older lived with a biological, foster, step, or adoptive child aged 12 to 17. About 11.9% of mothers (2.1 million) living with youths aged 12 to 17 had serious mental illness during the past year. About 3.2% of the mothers had both a serious mental illness and also reported illicit drug use, binge alcohol use, or heavy alcohol use during the past month. Youths living with a mother who had serious mental illness (SMI) were more likely to have used alcohol or an illicit drug during the past month (26.7%) than youths living with a mother who did not have SMI (18.8%).

The NSDUH Report:  Alcohol Use and Delinquent Behaviors among Youths   Youths who reported heavy alcohol use in the past month were the most likely to have participated in any of the six delinquent behaviors assessed in SAMHSA's National Survey on Drug Use and Health. Heavy drinking was defined as drinking five or more alcoholic beverages on the same occasion on each of 5 or more days in the past 30 days. All heavy alcohol users are also binge alcohol users, i.e., drank five or more drinks on the same occasion on at least one day in the past 30 days. In 2003, an estimated 9 million (36.1%) youths aged 12 to 17 had engaged in at least one delinquent behavior in the past year. Almost 6 million (23.8%) took part in a serious fight at school or work; 4.5 million (18.1%) took part in a group-against-group fight; 2.1 million (8.3%) attacked someone with the intent to seriously hurt them; 1.1 million (4.5%) stole or tried to steal something worth more than $50; over 900,000 (3.6%) sold illegal drugs; and over 900,000 (3.6%) carried a handgun during the past year.

Youths aged 12 or 13 who used inhalants in their lifetime were more than twice as likely to have been in a serious fight at school or work during the past year than youths their age who had never used inhalants. About 35% of youths aged 12 or 13 who used inhalants in their lifetime also used another illicit drug compared with 7.5% of youths aged 12 or 13 who had never used inhalants in their lifetime.

Between 2002 and 2003, the proportion of girls increased who participated in serious fights at school or work (from 16.2% to 20%) and who participated in a group-against-group fight in the past year (from 13.5% to 16.8%). Past year substance use was the most prevalent delinquent behavior among girls aged 12 to 17, with 36.5% (4.5 million) reporting past year alcohol use and 21.9% (2.7 million) reporting past year illicit drug use.

The NSDUH Report:  Risk & Protective Factors for Substance Use Among American Indian or Alaska Native Youths    SAMHSA's 2002/2003 National Survey on Drug Use and Health provided data on three categories of risk factors for substance use among American Indian or Alaska Native youths: individual/peers, family, and school. American Indian or Alaska Native youths were more likely than other youths to perceive moderate to no risk associated with substance use, to perceive their parents as not strongly disapproving of their substance use, and to believe that all or most of the students in their school get drunk at least once a week. According to American Indian or Alaska Native youths, their parents were about as likely as those of other youths to talk to their child about dangers of substance use, to let the youth know they had done a good job, to tell their youth that they were proud of something they had done, to make their youth do chores around the house or to limit the amount of time watching TV. However, parents of American Indian or Alaska Native youths were less likely to provide help with school homework or to limit the time out with friends on school nights.

The NSDUH Report:  Underage Drinking in Rural Areas   Based on SAMHSA's 2002 National Survey on Drug Use and Health, rates of current underage drinking among youth aged 12 to 17 was higher in rural than nonrural areas. Current underage drinking among those aged 18 to 20, however, were higher in nonrural areas. Rural youth aged 12 to 17 reported lower levels of perceived risk from alcohol use, less disapproval of alcohol use, and less perceived parental disapproval of underage drinking than those in nonrural areas. Binge drinking (defined as 5 or more drinks on the same occasion at least one day in the past month) was also higher among rural youth age 12 to 17 (4.1%) than nonrural (1.6%) but did not differ by rural status for those aged 18 to 20.

The NSDUH Report: Participation in Youth Activities and Substance Use Among Youths   Based on SAMHSA's National Survey on Drug Use and Health, during 2002, approximately 91% of youths aged 12 to 17, participated in one or more school-based, community-based, church or faith-based, or other activities (e.g., karate lessons) during the past year.

Rates of heavy drinking and binge drinking among young drivers varied by the States' Graduated Driver Licensing ratings, based on the extent to which they restrict driving behavior among young drivers. This report identifies the States categorized from most restrictive to least restrictive according to the 4 category rating scheme developed by the Insurance Institute for Highway Safety and the Traffic Injury Research Foundation.
