Prevalence of home pregnancy testing among adolescents

Home pregnancy test use and timing of pregnancy confirmation among people seeking health care

OBJECTIVES

Understanding the timing of pregnancy suspicion and confirmation, including the role of home pregnancy tests, can facilitate earlier entry into pregnancy-related care and identify individuals likely to be impacted by gestation-based abortion restrictions.

STUDY DESIGN

We use data from 259 pregnant individuals participating in a cross-sectional survey at 8 primary and reproductive health care clinics in 6 U.S. states (2016-2017). We use regression models to identify differences in utilization of HPTs, barriers to use, and to compare gestational duration at pregnancy confirmation.

RESULTS

Three-quarters (74%) of respondents took a home pregnancy test as the first step in confirming pregnancy; this figure was lower among adolescents versus young adults (65 vs 81%, p = 0.01). Two-thirds (64%) reported delays in home testing, higher among adolescents (85%). People taking a test at home confirmed pregnancy 10 days earlier than those first testing at a clinic (41.3 vs 51.8 days gestation, p = 0.02). Those that did not test at home cited concerns about test accuracy (42%) and difficulties accessing one (26%). While overall 21% confirmed pregnancy at ≥7 weeks gestation, and 35% at ≥6 weeks, confirmation at ≥7 weeks was higher among adolescents versus young adults (47 vs 13%, p = 0.001), Latina versus white women (28 vs 11%, p = 0.02), food insecure versus secure women (28 vs 17%, p = 0.06), and people with unplanned versus planned/mistimed pregnancies (25 vs 13%, p = 0.07).

CONCLUSIONS

Home pregnancy testing is common and associated with earlier pregnancy confirmation. Still, barriers to at-home testing are evident, particularly among adolescents. Efforts to expand access to home pregnancy tests and increase knowledge about their accuracy may be impactful in increasing utilization.

IMPLICATIONS

While at home pregnancy testing is common and facilitates earlier confirmation of pregnancy, one in 5 confirm pregnancy at 7 weeks gestation or later (and one in 3 do so at 6 weeks or later). Gestational bans in the first trimester will disproportionately prevent young people, people of color, and those living with food insecurity from being able to access abortion.

Can the HIV home test promote access to care? Lessons learned from the in-home pregnancy test

Adolescents and young adults are the fastest growing age group of human immunodeficiency virus (HIV) positive individuals in the US, and many who are infected do not know their HIV status. The HIV home test has the potential to help curb the HIV epidemic by improving detection of persons living with HIV and enabling them to seek follow-up care but it has not yet been evaluated in adolescents. Analogous to the home pregnancy test, which was met with much resistance and only successfully marketed during a time of social change, the HIV home test has been met with resistance since its FDA approval. This commentary summarizes the need to systematically evaluate positive and untoward/unanticipated effects of HIV home testing, particularly in young adults. The overall incidence of HIV has been declining in the US, yet it continues to grow at alarming rates for adolescents and young adults [1]. Almost 40 % of new HIV infections in the US are in this age group [2]. Further, many HIV infected adolescents and young adults are unaware of their infection. Nationwide, only 22.6 % of sexually active high school students have ever been tested for HIV [3]. While advances in drug regimens have transformed HIV into a chronic disease, infected individuals need to be identified and subsequently engaged in care [4].

Pregnancy test taking is a correlate of unsafe sex, contraceptive nonadherence, pregnancy, and sexually transmitted infections in adolescent and young adult women

OBJECTIVES

This study was conducted to examine the hypotheses that adolescent and young adult pregnancy test takers are at increased risk for unsafe sex, oral contraception (OC) nonadherence, and higher pregnancy and sexually transmitted infection (STI) rates.

METHODS

We conducted secondary analyses using data collected for a study on OC adherence among 1155 women 16-24 years of age. Data collected at baseline and 3, 6, and 12 months were used for the analyses.

RESULTS

At baseline, 33% of women reported having undergone ≥1 pregnancy test at home or a clinic during the past 3 months. Pregnancy test takers were more likely to have ≥3 sexual partners (odds ratio [OR] 2.12; 95% confidence interval [CI] 1.49-3.02) in the past year, report unprotected oral (OR 1.48; 95% CI 1.28-1.72) or anal sex (OR 1.78; 95% CI 1.32-2.39), be diagnosed with an STI (OR 1.76; 95% CI 1.23-2.51), become pregnant (hazards ratio 1.52; 95% CI 1.10-2.10), or not use any birth control method (OR 2.11; 95% CI 1.66-2.60). Moreover, they were less likely to continue using OC that was prescribed at baseline (OR 0.38; 95% CI 0.31-0.47) and to report being ambivalent about pregnancy (OR 0.73; 95% CI 0.60-0.90) compared to non-test takers.

CONCLUSIONS

Pregnancy test taking is an important correlate of high-risk sexual behaviors, OC nonadherence, and risk of subsequent pregnancy and STIs among adolescent and young adult women. Future interventions should target these women to decrease the risk of unintended pregnancies and STIs.

'Do it yourself' sexual health care: the user experience

OBJECTIVES

To describe client experience of self-management within a busy walk-in, sexual health service. Self-management in this context is self-registration and take-home pregnancy tests, chlamydia (Chlamydia trachomatis) and gonorrhoea (Neisseria gonorrhoeae) tests, or condoms dispensed from a free vending machine.

METHODS

Twenty-four in-depth, semi-structured interviews with users; 19 structured written reports from mystery shoppers paid to visit the service and report their experience; demographic details of those using the self-management option from the clinic database and 40 h of recorded observation in the clinic waiting room.

RESULTS

Between 2 September 2008 and 1 September 2009, 18 657 people had 28 545 attendances at the service. Of these, 1845 (6.5%) attendances were self-managed by 1555 individuals (8.3% of all clients). Of those who self-managed, 646 (35%) obtained a chlamydia and gonorrhoea test only, 597 (32%) obtained condoms only and 488 (27%) obtained a pregnancy test only. Users valued the opportunity to self-manage because of the reduced waiting times, autonomy and privacy that such a service offers. Some prefer the additional support offered within a clinical consultation. Users made personalised decisions about self-management based on time pressure, need for additional services and preferred source of support. Users often required help and advice from client support workers to complete the self-management process. This created problems with confidentiality.

CONCLUSIONS

Self-management is an acceptable option within sexual health services if informal support is available. Self-management options in clinical services could mean that 8% of clients at 6% of visits do not need to see a clinician, thus freeing up clinical capacity.

What's the Point? How Point-of-Care STI Tests Can Impact Infected Patients

Point-of-care (POC) tests are an important strategy to address the epidemic of sexually transmitted infections (STIs) among both adolescents and young adults. While access to care and confidentiality are major barriers to STI care, POC tests allow the clinician to provide immediate and confidential test results and treatment. In addition, POC test results constitute a "teachable moment"; that is, an opportunity to provide immediate feedback to the patient that may impact his/her risk behaviors. This paper reviews published data and manufacturer's product literature describing current point-of-care STI tests, including studies of test performance as well as impact on treatment intervals and disease spread. It presents theoretical and proposed pitfalls and solutions of implementing POC tests in clinical settings, non-traditional settings, and home care venues. We reviewed the available STI tests according to the World Health Organization (WHO) criteria for judging POC tests: the "ASSURRED" criteria (Affordable, Sensitive, Specific, User-friendly, Rapid and Robust, Equipment-free, Delivered).

Making sense of home pregnancy test instructions

OBJECTIVE

To examine readability and related formatting characteristics of English language instructions accompanying home pregnancy tests (HPTs).

METHODS

We identified 16 HPTs; however, because of duplicate instructions, our final sample included 13 unique sets of HPT instructions (brand names, n = 9; store brand, n = 4). Reading grade level of How to Use and Interpret Results and General Information sections were calculated using the Simple Measure of Gobbledygoop readability formula. Total number of graphics was tallied. Foldout dimension, text point size, and graphic dimensions were measured to the nearest millimeter with a standard ruler. We also assessed layout features, graphic characteristics, presence of a clear message, and presentation of manageable information using the User-Friendliness Tool (UFT).

RESULTS

Reading level ranged from 7th to 10th grade (mean +/- SD 8.5 +/- 0.9) for the How to Use and Interpret Results sections, and the Question and Answer sections ranged from 11th to 14th grade (mean +/- SD 12.1 +/- 0.7). Mean page length was 29.7 +/- 6.6 cm, and average page width was 23.3 +/- 7.0 cm, similar in size to an 8.5 x 11 inch sheet of paper. Graphics were used throughout HPT instructions (range 2-9), and most were similar in size to a U.S. quarter. None of the instructions scored high in all criteria on the UFT.

CONCLUSIONS

Readability and formatting characteristics of most HPT instructions do not meet recommended criteria for compliance with plain language guidelines. These findings underscore the need for improved instructions and ultimately improving patients' ability to use HPTs and interpret results with accuracy.

Adolescent girls with negative pregnancy tests

STUDY OBJECTIVES AND DESIGN: This descriptive study assessed background characteristics and attitudes about pregnancy held by adolescent girls presenting for pregnancy tests and receiving negative results. An additional aim was to determine types of health care services that would be of perceived benefit to them to reduce their risk of subsequent pregnancy.

SETTING

Two health care sites in an urban community included a hospital-based adolescent clinic and a hospital-based women's health care clinic.

PARTICIPANTS

Sixty-five adolescent, low-income, single women with negative pregnancy test results in a consecutive sample were included in the study. Participants had a mean age of 16.9 (+/-1.3) years and described themselves as 64.1% African American, 26.6% Latina and 9.4% white, with 81.5% enrolled or recently graduated from high school.

MAIN OUTCOME MEASURES

The following variables were included: demographic characteristics, reproductive health history, personal and perceived partner attitude about the negative pregnancy test result, perceived parental influences, and teens' suggestions for health care services to prevent unintended pregnancy.

RESULTS

Health history data revealed high risk status for unintended pregnancy and sexually transmitted infections (STI); 28.5% of participants were ambivalent or disappointed with their negative result, 71.4% were pleased and the majority felt that their partners would be more disappointed with the negative result than they were. Health care services that teens felt would be most helpful were one-on-one contraceptive education and discussion sessions with their own health care provider.

CONCLUSIONS

Sexually active teen women with negative pregnancy test results are at high risk of subsequent pregnancy and STIs, and present important opportunities for preventive reproductive health care during visits with health care providers.

Home STI testing: the adolescent female's opinion

PURPOSE

To assess sexually active adolescent females' attitudes of home tests for sexually transmitted infections.

METHODS

This study represents a follow-up to a study on adolescent attitudes toward different sampling methods for STI testing. In the initial study participants completed a pre-examination health survey, provided first void urine (FVU) and self-collected vaginal swab samples followed by a pelvic examination with STI screening by endocervical swabs. Participants' attitudes about the three collection techniques were assessed at the end of the visit. For the current study, this same group of ethnically diverse adolescents (13-20-years-old) was contacted by telephone 9 months after their initial clinic visit to re-assess their attitudes about the three specimen collection techniques and to evaluate their attitudes regarding the use of home STI testing. Friedman tests of mean ranks evaluated teens' rankings of STI sampling methods and multivariate regression analysis was used to identify predictors of home test preference.

RESULTS

Home urine testing was the first choice for STI screening followed by the FVU, self-obtained vaginal swab and endocervical swab collected in a clinical setting. FVU was preferred to self-collected vaginal swabs (p = .01). Adolescents who worried about having an STI were more likely to favor home urine testing (OR 5.5, p = .01). Only 22% would seek any STI screening if asymptomatic.

CONCLUSIONS

Because young women preferred home STI testing, this may be an additional option, as the foundation for such testing kits has progressed. Adolescent preferences may be heavily influenced by the pelvic examination experience. Because of the largely asymptomatic nature of CT infections, multiple screening options (clinical and home-based) need to be available to increase access to care.

Improving technologies to reduce abortion-related morbidity and mortality

This article reviews the technologies used to diagnose pregnancy and manage abortion in developing countries. The author discusses methods of diagnosing pregnancy--including physical examination, laboratory and home testing, and ultrasound--as well as methods for performing safe abortions. Due to manual vacuum aspiration (MVA) advances, vacuum aspiration has become safer and more feasible in low-resource settings. The discussion of medical abortion includes the advantages and limitations of mifepristone, misoprostol-only regimens, methotrexate, and other methods. The author stresses the importance of post-abortion care and post-abortion contraception and, in the conclusion, identifies six areas in which technology can reduce abortion-related morbidity and mortality: pregnancy prevention, early diagnosis of pregnancy, accurate assessment of gestation, standardization and supply of MVA technology, and simple and affordable regimens for medical abortion.

Teen home pregnancy test takers: more worried or more wishful?

OBJECTIVE

To test the hypothesis that teenagers who have taken home pregnancy tests are more ambivalent about remaining nonpregnant than those who have not and, for this reason, use contraceptives less consistently.

METHODS

A racially diverse group of 340 inadequately contracepting, nulligravida teens, 94 (28%) of whom had taken a home pregnancy test, was studied. At enrollment, participants completed a self-administered questionnaire, were counseled about contraceptive options, and were given the opportunity to initiate their method of choice. The enrollment tool assessed traditional teen-pregnancy risk factors, expectations about the effects of childbearing, common deterrents to contraceptive use, the desirability of remaining nonpregnant, and contraceptive use and plans.

RESULTS

Home pregnancy test takers were more apt to be unsure that they wanted to remain nonpregnant (relative risk [RR]:1.3; 95% confidence interval [CI]:1.1-1.6), principally because they were more likely to lack negative expectations about the effects of childbearing on their lives (odds ratio: 2.2; 95% CI = 1.2-4.0). Although no more likely to perceive deterrents to contraceptive use, pregnancy-test-kit users were more apt to have had unprotected sexual intercourse in the past (RR:1.3; 95% CI:1.1-1.5) and to plan to do so in the future (RR:1.7; 95% CI:1.1-3.3). Group differences in the desire to remain nonpregnant accounted for differences in contraceptive behavior and plans.

CONCLUSION

Home pregnancy test taking should be regarded as a red flag by those who care for adolescents; although they are as capable of using contraceptives as their peers, test takers are less apt to do so because they expect less negative consequences from childbearing and, for this reason, may benefit more from discussing childbearing expectations than contraceptive options.

Use of Home Pregnancy Tests Among Adolescent Women

Many adolescents use home pregnancy tests when they suspect pregnancy. However, because of developmental issues and greater variation in menstrual cycles, teens are at risk for obtaining false-negative test results. Moreover, with teens, the need for a pregnancy test often accompanies the need for comprehensive reproductive care including evaluation for sexually transmitted infections and contraception. This article reviews the mechanisms of home pregnancy testing including sensitivity, accuracy, and home testing procedures. Clinical strategies for improving the accuracy of home pregnancy tests for teen users are discussed. Lastly, policy implications to improve teens' access to more accurate pregnancy testing and to reproductive health services are suggested.
