Relationship between perceived parental monitoring and young adolescent girls' sexual and substance use behaviors

STUDY OBJECTIVE The purpose of the study was to examine the independent effects of perceived parental monitoring on sexual experience, contraceptive, and substance use. DESIGN, SETTING, AND PARTICIPANTS Adolescent females at an urban-based adolescent clinic (N = 174; 41% sexually experienced) rated the extent to which they were directly and indirectly monitored by their parents. MAIN OUTCOME MEASURES These perceptions were compared with reported contraceptive use as well as substance use. Direct parental monitoring was best described using two dimensions: direct monitoring and direct monitoring when with peers. RESULTS Direct monitoring was found to be associated with the use of hormonal birth control methods at last intercourse. Direct parental monitoring when with peers was found to be associated with less use of alcohol and cigarettes. CONCLUSIONS These data suggest that parental monitoring is a relevant factor for primary care physicians to explore during treatment.

Depo-provera in adolescents: Effects of early second injection or prior oral contraception

PURPOSE To examine the effects of an early second injection or prior use of oral contraceptive pills (OCP) on side effects of Depo-Provera during the early months of use in adolescents. METHODS Thirty-six girls, gynecologic age 4.2 +/- 0.3 years, and body mass index (BMI) 23.2 +/- 0.8, received the currently recommended injection of 150 mg every three months. Twenty-seven girls (gynecologic age 3.9 +/- 0.5 years, BMI 24.0 +/- 0.8) received the second injection six weeks after the first injection. Fifteen girls (gynecologic age 5.0 +/- 0.5, BMI 25.4 +/- 1.3) switched directly from an OCP to Depo-Provera. The patients were periodically assessed by their care providers. RESULTS Early administration of the second injection of Depo-Provera did not alter the bleeding episodes, onset of bleeding, or total days of bleeding (14.3 +/- 3.7 vs. 17.1 +/- 4.0, p = 0.62) during the three months interval following injection, compared with the standard second injection interval. Moreover, an excessive BMI gain (BMI increase 0.99 +/- 0.22 vs. 0.40 +/- 0.14, p = 0.03) was observed in these girls. Girls who switched directly from OCP showed no difference in the rate of BMI gain when compared to those not previously on OCP (BMI increase 0.38 +/- 0.3). Bleeding duration of these girls, however, was markedly reduced; the total number of days of bleeding was 5.7 +/- 1.9 (p = 0.0003) during the first three month interval, and 5.7 +/- 2.3 (p = 0.019) during the three month period following the second injection. This reduction did not persist beyond the first six months. CONCLUSIONS Early second Depo-Provera injection does not alter the experience of menstrual abnormalities, and predisposes to greater weight gain; OCP use prior to Depo-Provera results in a decrease in the duration of bleeding with no change in the weight gain rate.

Comparison of adolescent and young adult self-collected and clinician-collected samples for human papillomavirus.

OBJECTIVE: To examine the concordance between self-collected and clinician-collected samples for human papillomavirus (HPV) DNA. METHODS: Sexually active adolescent and young adult women aged 14–21 years (N = 101) were enrolled in a prospective cohort study of HPV testing. Participants self-collected vaginal samples for HPV DNA, and clinicians collected cervicovaginal samples for HPV DNA and a cervical cytology specimen. We determined concordance between the results of self- and clinician-collected specimens using a &kgr; statistic and McNemar’s test. RESULTS: Of the 51% of participants who were HPV positive, 53% had 1 type, 25% had 2 types, and 22% had 3 types or more; 25 different HPV types were identified. Self-collected samples detected more participants with HPV than clinician-collected samples (45% versus 42%, P = .65). When results were categorized into presence or absence of high-risk HPV types, agreement between self- and clinician-collected specimens was high (&kgr; 0.72) and the difference between test results was not significant (McNemar’s P = .41). However, when all HPV types detected were considered, agreement was perfect in only 51% of those with 1 or more types of high-risk HPV type. There was no association between agreement and age or HPV type. CONCLUSION: Self testing for HPV DNA may be sufficiently sensitive for the detection of high-risk HPV DNA among adolescent and young adult women in clinical settings. LEVEL OF EVIDENCE: II-3

Acceptability of human papillomavirus self testing in female adolescents

Objectives: To develop scales assessing acceptability of human papillomavirus (HPV) testing in adolescents, to compare acceptability of self to clinician testing, and to identify adolescent characteristics associated with acceptability. Methods: Female adolescents 14–21 years of age attending a hospital based teen health centre self collected vaginal samples and a clinician, using a speculum, collected cervicovaginal samples for HPV DNA. Acceptability of and preferences for self and clinician testing were assessed at baseline and 2 week visits. Results: The mean age of the 121 participants was 17.8 years and 82% were black. The acceptability scales demonstrated good internal consistency, reliability, test-retest reliability, and factorial validity. Scores were significantly lower for self testing than clinician testing on the acceptability scale and three subscales measuring trust of the test result, confidence in one’s ability to collect a specimen, and perceived effects of testing (p<0.01). Of those who reported a preference, 73% preferred clinician to self testing. Acceptability scores for both self and clinician testing increased significantly pre-examination to post-examination (p<0.01). Multivariable analyses demonstrated that race was independently associated with pre-examination and post-examination acceptability of self testing, and that sexual behaviours and gynaecological experiences were associated with specific acceptability subscales. Conclusions: This sample of adolescents found clinician testing for HPV to be more acceptable than self testing and preferred clinician to self testing. If self testing for HPV is offered in the future, clinicians should not assume that adolescent patients will prefer self testing. Instead, they should educate adolescents about available testing options and discuss any concerns regarding self collection technique or accuracy of test results.

Education about human papillomavirus and human papillomavirus vaccines in adolescents.

Purpose of review The purpose of this article is to review recent literature that may help guide the development of effective, evidence-based strategies to educate adolescents about human papillomavirus (HPV) and HPV vaccines. Educational strategies are essential, given several new and highly effective technologies to prevent HPV and related diseases such as cervical cancer. Recent findings Although little has been published regarding adolescent knowledge about HPV and HPV vaccines, studies conducted primarily in adult women demonstrate that knowledge generally is poor. Studies of adolescent attitudes about HPV vaccines have identified several modifiable factors associated with intention and confidence in ones ability to receive the vaccine, including higher perceived severity of cervical cancer and fewer barriers to vaccination. Studies of clinician attitudes about HPV vaccines have demonstrated that although clinicians generally support vaccination, some report concerns; for example, adolescents may practice riskier sexual behaviors after vaccination. Studies also show that clinicians believe that educational materials developed specifically for adolescents are essential. Summary The recent literature on adolescent knowledge about HPV and attitudes about HPV vaccines supports the importance of designing developmentally appropriate educational materials for adolescents about HPV and HPV vaccines, and provides guidance for the development of key educational messages.

Adolescent Preferences for Human Immunodeficiency Virus Testing Methods and Impact of Rapid Tests on Receipt of Results

PURPOSE Rapid human immunodeficiency virus (HIV) tests may be more acceptable to adolescents and may improve receipt of test results. We conducted a study to determine (a) adolescent preferences for different HIV testing methods (rapid oral fluid vs. rapid fingerstick vs. traditional venipuncture), (b) factors associated with choice of a rapid vs. traditional test, and (c) whether those who chose a rapid method were more likely to receive test results. METHODS Participants (N=99, 13-22 years old, both genders) were recruited from an urban hospital-based adolescent primary care clinic, agreed to HIV testing with their choice of method, and completed a questionnaire assessing demographic characteristics and attitudes about HIV testing. Logistic regression modeling was used to determine factors associated with choice of a rapid versus traditional test. RESULTS Half (50.5%) of participants chose rapid oral fluid testing, 30.3% traditional venipuncture testing, and 19.2% rapid fingerstick testing (p < .01). Factors independently associated with choice of a rapid versus traditional method included preference for an oral fluid versus blood test and perceived approval of HIV testing by ones healthcare provider. Participants who chose a rapid test were more likely to receive their test results within the follow-up period than participants who chose a traditional test (91.3% vs. 46.7%, p < .001). CONCLUSIONS In this study, 70% of adolescents preferred rapid to traditional HIV testing, and rapid testers were more likely to receive their results within the follow-up period. Offering rapid testing may lead to improved receipt of results among adolescents in urban primary care settings.

Experience with Side Effects and Health Risks Associated with Norplant@ Implant Use in Adolescents

Levonorgestrel implants (Norplant) have been recommended as a contraceptive method for teenage women. Our experience suggests that the use of Norplant implants in adolescents is associated with bleeding irregularities and modest weight gain. There is no effect on condom use or STD acquisition. Despite the bleeding irregularities, we documented high continuation rates, suggesting that with appropriate pre-insertion counseling, Norplant implants can be a successful contraceptive method for adolescent women.

Access to care for adolescents seeking weight loss surgery

Adolescents seeking weight loss surgery (WLS) frequently encounter obstacles obtaining treatment authorization from insurance carriers. This study identified factors influencing authorization for adolescents with clinical indications for WLS.

Methods for managing pelvic examination anxiety: individual differences and relaxation techniques.

Many adolescent girls anticipate pelvic examinations with anxiety. Providing information about the examination procedure is not sufficient to help all girls cope with their anxiety. An assessment of the adolescents coping style allows the care provider to tailor the educational process to the individual adolescent. Once the care provider has become proficient in relaxation techniques, they can be used along with education. This article reviews coping styles and relaxation techniques that can be integrated into practice.

Changes in human immunodeficiency virus testing rates among urban adolescents after introduction of routine and rapid testing.

OBJECTIVES To examine human immunodeficiency virus (HIV) testing rates among adolescents during a 3-year period to determine (1) if the rate of testing increased after publication of national recommendations for routine HIV testing in 2006, and again after the introduction of rapid testing in the clinic in 2007, and (2) factors associated with HIV testing. DESIGN Retrospective medical record review. SETTING Urban hospital-based adolescent primary care clinic. PARTICIPANTS Thirteen- to 22-year-old sexually experienced patients who had computerized billing data reflecting testing for sexually transmitted infections, including HIV. OUTCOME MEASURES Rates of HIV testing for each of 3 one-year phases-phase 1 (pre-routine testing recommendations), phase 2 (post-routine testing recommendations but pre-rapid testing), and phase 3 (post-rapid testing)-and factors associated with HIV testing. RESULTS In total, 9491 patients were included. The rate of HIV testing in phase 2 was significantly higher than the rate of testing in phase 1 (27.7% vs 12.6%, P < .001). The rate of testing in phase 3 was significantly higher than the rate of testing in phase 2 (44.6% vs 27.7%, P < .001) and phase 1 (P < .001). Factors independently associated with HIV testing included phase, older age, male sex, race, public insurance status, and having a genitourinary-related diagnosis during the same phase. CONCLUSIONS The HIV testing rates increased significantly following publication of recommendations for routine testing and further increased following introduction of rapid testing. Combining routine and rapid testing strategies may increase uptake of HIV testing among adolescents in primary care settings.
