Early sexual initiation: the role of peer norms.

OBJECTIVE: To elucidate which components of peer norms influence the process of sexual initiation for young adolescents. Design. Prospective cohort study. Setting. Fourteen elementary and middle schools in an urban public school district. Participants. The 1389 sixth-grade students who completed the questionnaire at the beginning (time 1) and at the end (time 2) of the school year comprise the study sample. Mean age at time 1 was 11.7 years. RESULTS: Of students entering the sixth grade, 30% (n = 416) reported having already initiated sexual intercourse, 5% (n = 74) reported initiating sexual intercourse during the sixth-grade school year (initiated group), and 63% (n = 873) reported not having initiated sexual intercourse by the end of the sixth-grade school year (never group). Demographic comparisons revealed that students in the initiated group were significantly more likely than students in the never group to be older (11.9 years vs 11.6 years), male (58% vs 37%), African-American (70% vs 51%), attending a poorer school (87% vs 85%), and living in an area with a high proportion of single-parent families (45% vs 41%). Self-reports and reports of peers' participation in nonsexual risk behaviors were more common for students in the initiated group. Students in the initiated group were more likely than students in the never group to perceive: 1) a high prevalence of sexual initiation among peers; 2) social gains associated with early sexual intercourse; and 3) younger age of peers' sexual initiation. Students in the never group were more likely to believe that sexually-experienced 12-year-old boys would be negatively stigmatized compared with students in the initiated group. Three predictive models were developed to test the relationship between peer norms and the process of initiation. These models demonstrate that the strongest predictor of sexual initiation in sixth grade is having high intention to do so at the beginning of sixth grade. The strongest predictor of high intention is belief that most friends have already had sexual intercourse. Perceptions of social gain and stigma for sexually-experienced 12-year-old boys act independently of intention to decrease risk of early sexual initiation. CONCLUSION: Early sexual intercourse is not an unplanned experience for many teens. Decisions about initiation are strongly bound to social context with peers playing an important role in creating a sense of normative behavior. Specific components of peer norms impact the process of sexual initiation in both positive and negative ways. Interventions aimed at delaying the onset of sexual initiation need to focus on cohort norms as well as on an individual's perceptions and behaviors.

Pregnancy among American Indian adolescents: reactions and prenatal care.

PURPOSE: Adolescent childbearing is twice as common among Native Americans as among all US races combined. Despite this, little is written about the psychosocial context or prenatal care of pregnant Native American adolescents. The objective of this study was to explore the reactions and prenatal care of Navajo and Apache adolescents delivering infants at Shiprock Indian Hospital, New Mexico, between January and March 1991, and Whiteriver Indian Hospital, Arizona, between May and June 1991. METHODS: Of the 25 eligible adolescents aged 19 years and younger, 15 Navajo and 5 Apache participants were interviewed within 24 hours of delivery. The interview consisted of 121 questions divided into 5 areas: sociodemographics, personal and family reactions to the pregnancy, knowledge and attitudes toward prenatal care, barriers to care, and ways to improve access to care. RESULTS: The mean age was 17.4 +/- 1.1, 6 were married, and 13 were primiparous. According to the Maternal Health Services Index, 5 adolescents received adequate, 13 intermediate, and 2 inadequate prenatal care. During the pregnancy, 3 adolescents used tobacco, 3 used alcohol, and none admitted to other drugs. Although only 1 adolescent planned the pregnancy, 15 were not using contraception when they became pregnant. In exploring reactions to the pregnancy, 13 adolescents were afraid to tell their families and 4 concealed the pregnancy until confronted. During the pregnancy, 7 adolescents described loneliness and 6 expressed suicidal ideation. Although over half reported no barriers to obtaining prenatal care, barriers that were noted by the remainder included transportation, family problems, and missing school. CONCLUSION: We conclude that pregnancy among many American Indian adolescents is unplanned and characterized by uncertainty and fear of disclosure, resembling the reactions to pregnancy of other adolescent populations. Furthermore, despite universal access to health services, many American Indian adolescents continue to experience barriers to care and receive intermediate or inadequate prenatal care. These preliminary findings suggest further research may help clarify how adolescent reactions to pregnancy and knowledge of prenatal care affect health care utilization.

Barriers to adolescent prenatal care.

It is estimated that over one-half of all adolescent mothers receive inadequate prenatal care. Our objectives were to explore the barriers to care as perceived by adolescents and to develop a model to identify adolescents at risk for inadequate care. Structured interviews were conducted with 101 adolescents less than 17 years of age who delivered infants at an urban university hospital between September 1988 and January 1989. All the interviews were conducted within 48 hr of delivery by a single investigator. The Maternal Health Services Index was used to divide subjects into those who received inadequate care (Group 1, n = 37) and those who received intermediate or adequate care (Group 2, n = 64). Both groups were predominantly black (99%), poor (mean Hollingshead score = 2), and unmarried (99%). Groups 1 and 2 differed (p less than 0.05) in 12 variables pertaining to beliefs about prenatal care and course during the pregnancy. Of the 12 variables, 7 comprised a stepwise logistic regression model designed to maximally differentiate Groups 1 and 2--negative attitudes towards physicians (20% vs 6%), perceived importance of first trimester care (78% vs 94%), confusion about available prenatal services (24% vs 5%), lack of health insurance (41% vs 16%), exposure to pregnant friends (76% vs 95%), mean gestational age at recognition of pregnancy (15 wks vs 11 wks), and desire for an adolescent-only prenatal clinic (78% vs 58%). The adjusted odds ratios of the variables ranged in declining order from 15.4 to 4.7. The attributable risks, or etiologic fractions, of the variables ranged in increasing order from 0.19 to 0.49. Receiver-operating characteristic curve analysis of the model demonstrated a curve area of 0.89 +/- 0.04, significantly better than chance. We conclude that the model clarifies the barriers to care and helps identify pregnant adolescents who are likely to receive inadequate prenatal care.
