Exploring Views about LARCs Among Parenting Rural Latinx Teenagers,Their Mothers,and Providers: Implications for Sexuality Education and Care

While long-acting reversible contraception (LARC) reduces risk of repeat-births, use remains low among rural Latinx adolescent mothers. This qualitative study identified perspectives about factors that influence LARC use among this population. Participants were dyads of parenting Latinx adolescent daughters and their mothers (n?=?9 dyads) and nurses (n?=?17). Findings revealed themes specific to this vulnerable population including (a) distinct ways LARC characteristics fit into parenting teenagers’ lives, (b) supportive health care climate toward LARCs, and (c) factors that inhibit LARC uptake. The study has implications for sexuality education that seeks to reduce repeat-births among this population.

An examination of emergency contraception use by undergraduate college students in the Midwest using the integrated behavioural model

The purpose of this study was to identify the factors that influence undergraduate college student use of emergency contraception (EC) and their level of knowledge about the product, in order to assist in the development of intervention programmes to increase its use, which could lead to lower rates of unintended pregnancies in this population. A response rate of 98.4% included 1553 surveys from students at 11 Midwestern universities. Students were predominantly female (63.5%), white (75.3%) and aged 18–21 years (80%). They ranged from first-year students (23.8%) through to fourth-year students (13.8%), with second-year students comprising the largest group (32.6%). The majority of respondents reported being heterosexual (92.1%), and 34.1% of those completing the questionnaire reported being in a committed relationship. Most respondents reported having had sexual intercourse at least once in their lifetime (78.9%). Of the 8.4% of sexually active students who had experienced an unintended pregnancy, 18.1% had used EC in the past 12 months. Knowledge of EC was not high; but as knowledge increased, the use of EC increased. The Integrated Behavioural Model predicted 50% of the variance in intention. Each construct contributed a portion of variance except experiential attitude, which was not statistically significant in the path analysis. The model could be used in any future interventions to increase EC use and decrease unintended pregnancies among college students.     

But I’m Married: Understanding Relationship Status and College Students’ Sexual Behaviors

Sexual health programs on college campuses are often directed toward single individuals with a focus on sexual risk. Using a sample of college students, this study examines how relationship status relates to sexual behaviors and may be a factor for sexual risk. Based on the study's results, expansion of sexual health programming on college campuses to include those married and in committed relationships is justified.     

Do Latino Youth Really Want to Get Pregnant?: Assessing Pregnancy Wantedness

Despite recent declines, Latinas bear a disproportionate burden of teen births. Understanding social, cultural, and demographic factors underlying pregnancy desire among Latino adolescents is needed to design effective teen pregnancy prevention interventions.

A questionnaire was completed by 794 Latino youth including a “pregnancy wantedness scale” (PWS) to assess attitudes toward an early pregnancy and socio-demographic variables. Regression analyses examined the association between these variables and PWS score. PWS scores for all groups were below but near the midpoint, suggesting ambivalence toward an early pregnancy. Being female, older, acculturated, using hormonal contraception, living with parents, and having an educated mother were significantly associated with lower PWS scores, but impacted youth differently depending on their sex and sexual experience. Multi-component Latino teen pregnancy prevention strategies should address behavioral and attitudinal differences based on sex and sexual experience and acknowledge the contribution of social determinants on pregnancy intentions.     

Preventing alcohol-exposed pregnancy among American-Indian youth

Research has determined that the prevention of alcohol-exposed pregnancies (AEP) must occur preconceptually, either by reducing alcohol intake in women planning pregnancy or at risk for becoming pregnant, or by preventing pregnancy in women drinking at risky levels. One such AEP prevention programme with non-pregnant American-Indian (AI) women is the Oglala Sioux Tribe (OST) Changing High-risk alcohOl use and Increasing Contraception Effectiveness Study (CHOICES) Programme, which shows promise in reducing AEP risk in AI women aged 18 or older. A community needs assessment was conducted with key informant interviews and focus groups with an emphasis on how to expand OST CHOICES. To identify relevant inter-related themes, a content analysis was conducted on qualitative feedback from the focus groups and interviews. Altogether, key informant interviews were completed with 25 health and social service professionals. Eight focus groups were held with 58 AI participants, including adult women of child-bearing age, elder women, and adult men. Several sub-themes regarding the prevention of AEP with youth were identified, expanding the OST CHOICES curriculum into the schools, and the role of family and culture within AEP prevention.
