Md. Resnick et al., PROTECTING ADOLESCENTS FROM HARM - FINDINGS FROM THE NATIONAL LONGITUDINAL-STUDY ON ADOLESCENT HEALTH, JAMA, the journal of the American Medical Association, 278(10), 1997, pp. 823-832
Context.-The main threats to adolescents' health are the risk behavior
s they choose, How their social context shapes their behaviors is poor
ly understood. Objective.-To identify risk and protective factors at t
he family, school, and individual levels as they relate to 4 domains o
f adolescent health and morbidity: emotional health, violence, substan
ce use, and sexuality. Design.-Cross-sectional analysis of interview d
ata from the National Longitudinal Study of Adolescent Health. Partici
pants.-A total of 12 118 adolescents in grades 7 through 12 drawn from
an initial national school survey of 90 118 adolescents from 80 high
schools plus their feeder middle schools. Setting.-The interview was c
ompleted in the subject's home. Main Outcome Measures.-Eight areas wer
e assessed: emotional distress; suicidal thoughts and behaviors; viole
nce; use of 3 substances (cigarettes, alcohol, marijuana); and 2 types
of sexual behaviors (age of sexual debut and pregnancy history), Inde
pendent variables included measures of family context, school context,
and individual characteristics. Results.-Parent-family connectedness
and perceived school connectedness were protective against every healt
h risk behavior measure except history of pregnancy, Conversely, ease
of access to guns at home was associated with suicidality (grades 9-12
: P<.001) and violence (grades 7-8: P<.001; grades 9-12: P<.001). Acce
ss to substances in the home was associated with use of cigarettes (P<
.001), alcohol (P<.001), and marijuana (P<.001) among all students. Wo
rking 20 or more hours a week was associated with emotional distress o
f high school students (P<.01), cigarette use (P<.001), alcohol use (P
<.001), and marijuana use (P<.001). Appearing ''older than most'' in c
lass was associated with emotional distress and suicidal thoughts and
behaviors among high school students (P<.001); it was also associated
with substance use and an earlier age of sexual debut among both junio
r and senior high students, Repeating a grade in school was associated
with emotional distress among students in junior high (P<.001) and hi
gh school (P<.01) and with tobacco use among junior high students (P<.
001). On the other hand, parental expectations regarding school achiev
ement were associated with lower levels of health risk behaviors; pare
ntal disapproval of early sexual debut was associated with a later age
of onset of intercourse (P<.001). Conclusions.-Family and school cont
exts as well as individual characteristics are associated with health
and risky behaviors in adolescents. The results should assist health a
nd social service providers, educators, and others in taking the first
steps to diminish risk factors and enhance protective factors for our
young people.
