Untangling the health disparities of teen pregnancy

The Impact of Residing in a Gang Territory on Adverse Birth Outcomes: Evidence from Los Angeles

Gang violence remains an ongoing crisis in many communities in the United States. This paper assesses the potential association of gang-occupied neighborhoods with birth outcomes. Adverse birth outcomes serve as a "barometer" of population health, denoting both poor conditions for human development and portending future public health concerns. We draw upon (1) Los Angeles County Vital Statistics Birth Records (2008-2012), (2) GIS information on gang territory boundaries, (3) LA city geo-coded crime data, and (4) the 2010 U.S. Census and 2006-2010 American Community Survey. We find an association between gang-occupied neighborhoods and adverse birth outcomes; however, this association is largely explained by other neighborhood socio-demographic characteristics, crime notwithstanding. We also find that gangland neighborhoods tend to exacerbate the effects of crime for all birth outcomes, but only significantly so for small for gestational age births. Lastly, gang co-residence, crime, and other neighborhood demographics explain a substantial portion of socioeconomic and racial/ethnic disparities in adverse birth outcomes. Gangland neighborhoods appear to be a novel contributor to both population health and health disparities. Future studies should address these relationships in a broad range of metropolitan settings, paying careful attention to causal linkages and moderating effects of gangs and crime.

Race, Socioeconomic Status, and Sex Hormones among Male and Female American Adolescents

Although early sexual initiation and childbearing are major barriers against the upward social mobility of American adolescents, particularly those who belong to a low socioeconomic status (SES) and racial minorities such as Blacks, less is known on how SES and race correlate with adolescents' sex hormones. An understanding of the associations between race and SES with adolescents' sex hormones may help better understand why racial, and SES gaps exist in sexual risk behaviors and teen pregnancies. To extend the existing knowledge on social patterning of adolescents' sex hormones, in the current study, we studied social patterning of sex hormones in a national sample of male and female American adolescents, with a particular interest in the role of race and SES. For this cross-sectional study, data came from the baseline data (wave 1) of the Adolescent Brain Cognitive Development (ABCD) study, a national longitudinal prospective study of American adolescents. This analysis included 717 male and 576 female non-Hispanic White or Black adolescents ages 9-10. The dependent variables were sex hormones (testosterone for males and estradiol for females). Independent variables were age, race, family marital status, parental education, and financial difficulties. For data analysis, linear regression models were used. Age, race, parental education, and financial difficulties were associated with estradiol in female and testosterone levels in male adolescents. Associations were not identical for males and females, but the patterns were mainly similar. Low SES explained why race is associated with higher estradiol in female adolescents. Marital status of the family did not correlate with any of the sex hormones. Being Black and low SES were associated with a higher level of sex hormones in male and female adolescents. This information may help us understand the social patterning of sexual initiation and childbearing. Addressing racial and economic inequalities in early puberty, sexual initiation, and childbearing is an essential part of closing the racial and economic gaps in the US.

Contributing factors of teenage pregnancy among African-American females living in economically disadvantaged communities

AIM

To identify contributing factors that increased the risk of pregnancy among African-American adolescent females living in economically disadvantaged communities and to evaluate the current pregnancy prevention programs addressing these factors in order to provide suggestions for the development of tailored pregnancy prevention programs for this target population.

BACKGROUND

Pregnancy rates among adolescents in the United States have declined over the past several years. Despite this trend, the pregnancy rate for African-American adolescent females is disproportionately higher than the adolescent pregnancy rates for other ethnicities. Limited attempts have been made to compile and synthesize the factors that increase risk of pregnancy in this population or to evaluate the effectiveness of intervention programs for African-American females that incorporate these risk factors.

METHOD

An integrative literature review was conducted to identify the major contributing factors of pregnancy among African American adolescents living in economically disadvantaged areas.

RESULTS

Of the identified contributing risk factors for early pregnancy among African-American adolescent females, the five most supported risk factors were: parental influence, peer influence, social messages, substance use including alcohol, and pregnancy desire. Twelve pregnancy prevention programs were identified that addressed one or more of the five contributing factors to pregnancy. Parental influence and social messages were the most addressed factors among these programs.

CONCLUSIONS

This review found five contributing factors related to teenage pregnancy; however, current intervention programs are not well addressed substance use as a component of alcohol use. Thus, development of a tailored pregnancy prevention program incorporating those factors will help decrease the high pregnancy rate among this target population.

Intervention Now to Eliminate Repeat Unintended Pregnancy in Teenagers (INTERUPT): a systematic review of intervention effectiveness and cost-effectiveness, and qualitative and realist synthesis of implementation factors and user engagement

BACKGROUND

The UK has one of the highest rates of teenage pregnancies in Western Europe. One-fifth of these are repeat pregnancies. Unintended conceptions can cause substantial emotional, psychological and educational harm to teenagers, often with enduring implications for life chances. Babies of teenage mothers have increased mortality and are at a significantly increased risk of poverty, educational underachievement and unemployment later in life, with associated costs to society. It is important to identify effective, cost-effective and acceptable interventions.

OBJECTIVES

To identify who is at the greatest risk of repeat unintended pregnancies; which interventions are effective and cost-effective; and what the barriers to and facilitators of the uptake of these interventions are.

DATA SOURCES

We conducted a multistreamed, mixed-methods systematic review informed by service user and provider consultation to examine worldwide peer-reviewed evidence and UK-generated grey literature to find and evaluate interventions to reduce repeat unintended teenage pregnancies. We searched the following electronic databases: MEDLINE and MEDLINE In-Process & Other Non-Indexed Citations, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library (Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and the Health Technology Assessment Database), EMBASE (Excerpta Medica database), British Nursing Index, Educational Resources Information Center, Sociological Abstracts, Applied Social Sciences Index and Abstracts, BiblioMap (the Evidence for Policy and Practice Information and Co-ordinating Centre register of health promotion and public health research), Social Sciences Citation Index (supported by Web of Knowledge), Research Papers in Economics, EconLit (American Economic Association's electronic bibliography), OpenGrey, Scopus, Scirus, Social Care Online, National Research Register, National Institute for Health Research Clinical Research Network Portfolio and Index to THESES. Searches were conducted in May 2013 and updated in June 2014. In addition, we conducted a systematic search of Google (Google Inc., Mountain View, CA, USA) in January 2014. Database searches were guided by an advisory group of stakeholders.

REVIEW METHODS

To address the topic's complexities, we used a structured, innovative and iterative approach combining methods tailored to each evidence stream. Quantitative data (effectiveness, cost-effectiveness, risk factors and effect modifiers) were synthesised with reference to Cochrane guidelines for evaluating evidence on public health interventions. Qualitative evidence addressing facilitators of and barriers to the uptake of interventions, experience and acceptability of interventions was synthesised thematically. We applied the principles of realist synthesis to uncover theories and mechanisms underpinning interventions (what works, for whom and in what context). Finally, we conducted an overarching narrative of synthesis of evidence and gathered service user feedback.

RESULTS

We identified 8664 documents initially, and 816 in repeat searches. We filtered these to 12 randomised controlled trials (RCTs), four quasi-RCTs, 10 qualitative studies and 53 other quantitative studies published between 1996 and 2012. None of the RCTs was based in the UK. The RCTs evaluated an emergency contraception programme and psychosocial interventions. We found no evidence for effectiveness with regard to condom use, contraceptive use or rates of unprotected sex or use of birth control. Our primary outcome was repeat conception rate: the event rate was 132 of 308 (43%) in the intervention group versus 140 of 289 (48%) for the control goup, with a non-significant risk ratio (RR) of 0.92 [95% confidence interval (CI) 0.78 to 1.08]. Four studies reported subsequent birth rates: 29 of 237 (12%) events for the intervention arm versus 46 out of 224 (21%) for the control arm, with a RR of 0.60 (95% CI 0.39 to 0.93). Many repeat conceptions occurred in the context of poverty, low expectations and aspirations, and negligible opportunities. Service user feedback suggested that there were specific motivations for many repeat conceptions, for example to replace loss or to please a partner. Realist synthesis highlighted that context, motivation, planning for the future and letting young women take control with connectedness and tailoring provide a conceptual framework for future research.

LIMITATIONS

Included studies rarely characterised adolescent pregnancy as intended or unintended, that is interventions to reduce repeat conceptions rarely addressed whether or not pregnancies were intended. Furthermore, interventions were often not clearly defined, had multiple aims and did not indicate which elements were intended to address which aims. Nearly all of the studies were conducted in the USA and focused largely on African American or Hispanic and Latina American populations.

CONCLUSIONS

We found no evidence to indicate that existing interventions to reduce repeat teenage pregnancy were effective; however, subsequent births were reduced by home-based interventions. Qualitative and realist evidence helped to explain gaps in intervention design that should be addressed. More theory-based, rigorously evaluated programmes need to be developed to reduce repeat teenage pregnancy in the UK.

Never-pregnant African American adolescent girls' perceptions of adolescent pregnancy

Despite the decrease in adolescent pregnancy rates, rates among African American girls remain higher than other racial/ethnic adolescent groups. This descriptive qualitative study explored never-pregnant African American adolescent girls' perceptions about adolescent pregnancy. Sixty-four participants participated in individual interviews and focus groups. Individual interviews examined beliefs about adolescent pregnancy and perceptions of life changes resulting from becoming pregnant during adolescence. Focus groups were held to validate findings from the interviews. Participants agreed that becoming pregnant during adolescence would negatively impact their education, family, and peers. Participants anticipated feelings of shame and embarrassment in the event that they became pregnant.

Religiosity and the Transition to Nonmarital Parity

Nonmarital parity is associated with several negative outcomes, including health problems, educational problems, and poverty. Understanding the risk and protective factors associated with nonmarital parenthood can inform policy and interventions, reducing both the incidences and associated consequences. The current study focuses on how intrinsic and extrinsic religiosity (the degree to which individuals or groups employ religious ideology in forming values and making decisions) are related to the timing of nonmarital parity using discrete time hazard modeling of a nationally representative sample of adolescent females (N=7,367) from the National Longitudinal Study of Adolescent Health. The majority of the sample (86 %) claimed a religious affiliation and almost a third (32 %) had a nonmarital birth during the study. Even though the majority of the sample is White (67 %), Black and Hispanic females were more likely to experience a nonmarital birth. Results indicate that intrinsic and extrinsic religiosity and religious affiliation assert protective effects for some populations while religious affiliation increases risk in the full model. Recommendations for policy, intervention, and future research are offered.

Neighborhood contexts experienced by young Mexican-American women: enhancing our understanding of risk for early childbearing

Young Mexican-American women are disproportionately affected by teen pregnancy and early childbearing. While many of the studies that have investigated this population's high risk for early childbearing have focused predominantly on micro-level factors, a growing body of research has demonstrated the importance of neighborhood-level factors in shaping risk for this outcome. In order to elucidate the role of neighborhood context with regards to early childbearing among adolescent Mexican-American women, it is important to understand what these young women consider to be their neighborhood context and how they experience these contexts. This study utilized a mixed-methods design incorporating participatory photography, photo-elicitation, and focus groups in order to gain a more nuanced understanding of how neighborhood context is conceptualized and experienced by Mexican-American young women, and how these experiences may influence risk for early childbearing. Major findings include: (1) participants view the blocks on which they live as their neighborhood, but their exposure to neighborhood context extends beyond these blocks and includes the transient spaces they move through daily; and (2) within their neighborhood contexts, participants are influenced by experiences of discrimination and the presence of gangs and violence. These findings point to the importance of neighborhood-level factors in the lives of adolescent Mexican-American women, and may be used to inform future studies looking at the role of neighborhood context in shaping risk for early childbearing among this population.

Exposure to partner, family, and community violence: gang-affiliated Latina women and risk of unintended pregnancy

While teen pregnancy rates appear to be declining in the U.S.A. overall, the rate of decline among young Latinas has been less than other ethnic groups. Among the myriad factors associated with elevated pregnancy rates, for Latina girls living in the inner city, exposure to gang and community violence may be a critical context for increased pregnancy risk. This study explores the relationship between gang involvement and reproductive health, and the pathways through which childhood, family, and relationship violence exposure may lead to unintended pregnancy. Interviews of 20 young adult Latinas with known gang involvement in Los Angeles County were audiotaped, transcribed, and coded for key themes related to violence exposure and reproductive health. Limited access to reproductive health care compounded by male partner sexual and pregnancy coercion, as well as physical and sexual violence, emerged in the interviews. Exposures to interparental domestic violence, childhood physical and sexual abuse, and gang violence were prominent and closely associated with unhealthy and abusive intimate relationships. Adverse childhood experiences and exposure to partner, family, and community violence impact the reproductive lives and choices of young Latina women in gangs. These findings may guide targeted pregnancy prevention efforts among urban gang-affiliated Latinas as well as encourage the integration of sexual violence prevention and reproductive health promotion within gang violence intervention programs.

Predictors of Coparenting Relationship Quality in African American Single Mother Families: An Ecological Model

Nonmarital coparents, or adults who assist mothers with childrearing, play a significant role in the lives of African American single mothers and their children. Yet relatively little research has examined correlates of the quality of the coparenting relationship in these families. Using a broad ecological framework, the current study examined correlates of maternal-report of coparenting relationship quality in a sample of 242 low-income African American single mother families in the southeastern United States. Cross-sectionally, at each of two time points, neighborhoods characterized by lower levels of risk, higher levels of lax maternal parenting, and higher levels of maternal depressive symptoms were associated with a more compromised coparenting relationship.These findings were partially replicated in longitudinal analyses predicting coparenting relationship quality at Assessment 2 from Assessment 1 variables. Clinical implications and future research directions are discussed.

Runaway and pregnant: risk factors associated with pregnancy in a national sample of runaway/homeless female adolescents

PURPOSE

Homeless youth are at particularly high risk for teen pregnancy; research indicates as many as 20% of homeless young women become pregnant. These pregnant and homeless teens lack financial resources and adequate health care, resulting in increased risk for low-birth-weight babies and high infant mortality. This study investigated individual and family-level predictors of teen pregnancy among a national sample of runaway/homeless youth in order to better understand the needs of this vulnerable population.

METHODS

Data from the Runaway/Homeless Youth Management Information System (RHY MIS) provided a national sample of youth seeking services at crisis shelters. A sub-sample of pregnant females and a random sub-sample (matched by age) of nonpregnant females comprised the study sample (N = 951). Chi-square and t tests identified differences between pregnant and nonpregnant runaway females; maximum likelihood logistic regression identified individual and family-level predictors of teen pregnancy.

RESULTS

Teen pregnancy was associated with being an ethnic minority, dropping out of school, being away from home for longer periods of time, having a sexually transmitted disease, and feeling abandoned by one's family. Family factors, such as living in a single parent household and experiencing emotional abuse by one's mother, increased the odds of a teen being pregnant.

CONCLUSIONS

The complex problems associated with pregnant runaway/homeless teens create challenges for short-term shelter services. Suggestions are made for extending shelter services to include referrals and coordination with teen parenting programs and other systems of care.

Gang exposure and pregnancy incidence among female adolescents in San Francisco: evidence for the need to integrate reproductive health with violence prevention efforts

Among a cohort of 237 sexually active females aged 14-19 years recruited from community venues in a predominantly Latino neighborhood in San Francisco, California, the authors examined the relation between gang exposure and pregnancy incidence over 2 years of follow-up between 2001 and 2004. Using discrete-time survival analysis, they investigated whether gang membership by individuals and partners was associated with pregnancy incidence and determined whether partnership characteristics, contraceptive behaviors, and pregnancy intentions mediated the relation between gang membership and pregnancy. Pregnancy incidence was determined by urine-based testing and self-report. Latinas represented 77% of participants, with one in five born outside the United States. One quarter (27.4%) became pregnant over follow-up. Participants' gang membership had no significant effect on pregnancy incidence (hazard ratio = 1.25, 95% confidence interval: 0.54, 3.45); however, having partners who were in gangs was associated with pregnancy (hazard ratio = 1.90, 95% confidence interval: 1.09, 3.32). The male partner's perceived pregnancy intentions and having a partner in detention each mediated the effect of partner's gang membership on pregnancy risk. Increased pregnancy incidence among young women with gang-involved partners highlights the importance of integrating reproductive health prevention into programs for gang-involved youth. In addition, high pregnancy rates indicate a heightened risk for sexually transmitted infections.

Concept analysis: sexual decision-making in adolescence

PURPOSE

This papers aims to clarify and explore the topic of adolescent decision-making regarding sexual activity.

SOURCES

Published literature.

CONCLUSIONS

Adolescent decision-making regarding the initiation or continuation of sexual activity is influenced by desire for intimacy, perceived relationship safety, problem-solving ability, cognitive ability, family and peer relationships, and concern regarding pregnancy or sexually transmitted infection.
