RESUMO
Importance: The current method of BRCA testing for breast and ovarian cancer prevention, which is based on family history, often fails to identify many carriers of pathogenic variants. Population-based genetic testing offers a transformative approach in cancer prevention by allowing for proactive identification of any high-risk individuals and enabling early interventions. Objective: To assess the lifetime incremental effectiveness, costs, and cost-effectiveness of population-based multigene testing vs family history-based testing. Design, Setting, and Participants: This economic evaluation used a microsimulation model to assess the cost-effectiveness of multigene testing (BRCA1, BRCA2, and PALB2) for all women aged 30 to 35 years compared with the current standard of care that is family history based. Carriers of pathogenic variants were offered interventions, such as magnetic resonance imaging with or without mammography, chemoprevention, or risk-reducing mastectomy and salpingo-oophorectomy, to reduce cancer risk. A total of 2000 simulations were run on 1â¯000â¯000 women, using a lifetime time horizon and payer perspective, and costs were adjusted to 2022 US dollars. This study was conducted from September 1, 2020, to December 15, 2023. Main Outcomes and Measures: The main outcome measure was the incremental cost-effectiveness ratio (ICER), quantified as cost per quality-adjusted life-year (QALY) gained. Secondary outcomes included incremental cost, additional breast and ovarian cancer cases prevented, and excess deaths due to coronary heart disease (CHD). Results: The study assessed 1â¯000â¯000 simulated women aged 30 to 35 years in the US. In the base case, population-based multigene testing was more cost-effective compared with family history-based testing, with an ICER of $55â¯548 per QALY (95% CI, $47â¯288-$65â¯850 per QALY). Population-based multigene testing would be able to prevent an additional 1338 cases of breast cancer and 663 cases of ovarian cancer, but it would also result in 69 cases of excess CHD and 10 excess CHD deaths per million women. The probabilistic sensitivity analyses show that the probability that population-based multigene testing is cost-effective was 100%. When the cost of the multigene test exceeded $825, population-based testing was no longer cost-effective (ICER, $100â¯005 per QALY; 95% CI, $87â¯601-$11â¯6323). Conclusions and Relevance: In this economic analysis of population-based multigene testing, population-based testing was a more cost-effective strategy for the prevention of breast cancer and ovarian cancer when compared with the current family history-based testing strategy at the $100â¯000 per QALY willingness-to-pay threshold. These findings support the need for more comprehensive genetic testing strategies to identify pathogenic variant carriers and enable informed decision-making for personalized risk management.

BACKGROUND: Despite the growing concern that people with HIV (PWH) will experience a disproportionate burden of dementia as they age, very few studies have examined the sex-specific prevalence of dementia, including Alzheimer disease and related dementias (AD/ADRD) among older PWH versus people without HIV (PWOH) using large national samples. METHODS: We constructed successive cross-sectional cohorts including all PWH aged 65+ years from U.S. Medicare enrollees and PWOH in a 5% national sample of Medicare data from 2007 to 2019. All AD/ADRD cases were identified by ICD-9-CM/ICD-10-CM diagnosis codes. Prevalence of AD/ADRD was calculated for each calendar year by sex-age strata. Generalized estimating equations were used to assess factors associated with dementia and calculate the adjusted prevalence. RESULTS: PWH had a higher prevalence of AD/ADRD, which increased over time compared with PWOH, especially among female beneficiaries and with increasing age. For example, among those aged 80+ years, the prevalence increased from 2007 to 2019 (females with HIV: 31.4%-44.1%; females without HIV: 27.4%-29.9%; males with HIV: 26.2%-33.3%; males without HIV: 21.0%-23.5%). After adjustment for demographics and comorbidities, the differences in dementia burden by HIV status remained, especially among older age groups. CONCLUSIONS: Older Medicare enrollees with HIV had an increased dementia burden over time compared with those without HIV, especially women and older subjects. This underscores the need to develop tailored clinical practice guidelines that facilitate the integration of dementia and comorbidity screening, evaluation, and management into the routine primary care of aging PWH.

PURPOSE: Despite substantially higher prevalence of depression among people living with HIV/AIDS (PLWHA), few data exist on the incidence and correlates of depression in this population. This study assessed the effect of HIV infection, age, and cohort period on the risk of developing depression by sex among older U.S. Medicare beneficiaries. METHODS: We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries (1996-2015). People with newly diagnosed (n = 1309) and previously diagnosed (n = 1057) HIV were individually matched with up to three beneficiaries without HIV (n = 6805). Fine-Gray models adjusted for baseline covariates were used to assess the effect of HIV status on developing depression by sex strata. RESULTS: PLWHA, especially females, had higher risk of developing depression within five years. The relative subdistribution hazards (sHR) for depression among three HIV exposure groups differed between males and females and indicated a marginally significant interaction (p = 0.08). The sHR (95% CI) for newly and previously diagnosed HIV (vs. people without HIV) were 1.6 (1.3, 1.9) and 1.9 (1.5, 2.4) for males, and 1.5 (1.2, 1.8) and 1.2 (0.9, 1.7) for females. The risk of depression increased with age [sHR 1.3 (1.1, 1.5), 80 + vs. 65-69] and cohort period [sHR 1.3 (1.1, 1.5), 2011-2015 vs. 1995-2000]. CONCLUSIONS: HIV infection increased the risk of developing depression within 5 years, especially among people with newly diagnosed HIV and females. This risk increased with older age and in recent HIV epidemic periods, suggesting a need for robust mental health treatment in HIV primary care.

Initial uptake of the cancer-preventative human papillomavirus (HPV) vaccine in the US was slow, especially among adolescent males. To address this, the US Centers for Disease Control and Prevention (CDC) partnered with the Hager Sharp communications development company to launch a national campaign in 2015 to improve physician counseling and rebrand the vaccine as cancer prevention. In this study, we compared HPV vaccination rates among 13-17-year-old males before (2010-2014) and after (2015-2019) the CDC-Hager Sharp campaign using National Immunization Survey-Teen data to determine the potential impact of this campaign on improving vaccine uptake among adolescent males. Employing provider-verified vaccination data available for 49,644 males from 2010 to 2014 and 47,943 males from 2015 to 2019, we found that the adjusted prevalence ratios of 13-17-year-old males who initiated and completed the vaccine series increased approximately 5-fold between the 2010-2014 and 2015-2019 periods. Increases in post-campaign initiation/completion rates were greatest among respondents with mothers who were married or had attended college, respondents who lived in the Northeast or Midwest, and those from households with annual incomes > $75,000. Together, these data suggest that the campaign contributed to the observed increase in HPV vaccine uptake among adolescent males. Although sociodemographic disparities were identified, the greater improvement in vaccination rates observed among individuals with higher socio-demographic status may simply reflect their relatively poorer rates of initial vaccine uptake. Overall, the data suggest that provider-targeted campaigns can be a useful tool to boost vaccinations and should be considered for inclusion in future vaccination campaigns.

OBJECTIVE: Despite disproportionally high prevalence of HIV and depression in persons with disabilities, no data have been published on the incidence and correlates of depression in Medicare beneficiaries with disabilities. We assessed the effect of HIV infection on developing depression in this population. DESIGN: We conducted a retrospective matched cohort study using a 5% sample of Medicare beneficiaries who qualified for disability coverage (1996-2015). METHODS: Beneficiaries with incident ( n â=â2438) and prevalent ( n â=â5758) HIV were individually matched with beneficiaries without HIV (HIV-, n â=â20â778). Fine-Gray models with death as a competing risk were used to assess the effect of HIV status, age, and cohort period on developing depression by sex strata. RESULTS: Beneficiaries with HIV had a higher risk of developing depression within 5 years ( P â<â0.0001). Sex differences were observed ( P â<â0.0001), with higher subdistribution hazard ratios (sHR) in males with HIV compared with controls. The risk decreased with age ( P â<â0.0001) and increased in recent years ( P â<â0.0001). There were significant age-HIV ( P â=â0.004) and period-HIV ( P â=â0.006) interactions among male individuals, but not female individuals. The sHR was also higher within the first year of follow-up among male individuals, especially those with incident HIV. CONCLUSION: Medicare enrollees with disabilities and HIV had an increased risk of developing depression compared to those without HIV, especially among males and within the first year of HIV diagnosis. The HIV-depression association varied by sex, age, and cohort period. Our findings may help guide screening and comprehensive management of depression among subgroups in this vulnerable population.

Knowledge, attitudes, and patient preferences about genetic testing and subsequent risk management for cancer prevention among average risk populations are understudied, especially among Hispanics. This study was to assess these items by conducting an in-person survey in this understudied population. We conducted in-person surveys using a self-administered, structured questionnaire among young women in 2017. Survey questions were adapted from other validated surveys. This study had 677 participants in the final analyses. Data were collected in 2017 and analyzed in 2018 and 2019. Participants had little knowledge about genes or breast cancer risk, but most felt that genetic testing for cancer prevention is "a good idea" (87.0%), "a reassuring idea" (84.0%), and that "everyone should get the test" (87.7%). Most (64.0%) of these women would pay up to $25 for the test, 29.3% would pay $25-$500, and < 10% would pay more than $500 for the test. When asked about a hypothetical scenario of high breast cancer risk, 34.2% Hispanics and 24.5% non-Hispanics would choose chemoprevention. Women would be less likely to choose risk reduction procedures, such as mastectomy (19.6% among Hispanics and 15.1% among non-Hispanics) and salpingo-oophorectomy (11.8% among Hispanics and 10.7% among non-Hispanics). In this low-income, mostly Hispanic population, knowledge about genetic testing and cancer risk is poor, but most have positive opinions about genetic testing for cancer prevention. However, their strong preference for chemoprevention and lesser preference for prophylactic surgeries in a hypothetical scenario underscore the importance of genetic counseling and education.

OBJECTIVE: People with HIV infection experience excessive mortality compared with their noninfected counterparts. It is unclear whether the impact of HIV infection on mortality varies by comorbidities or whether sex difference exists in this relationship. This study assessed the effect of newly diagnosed HIV infection on overall mortality among Medicare beneficiaries for both disabled and older adults (≥65âyears old) based on their original entitlement. METHODS: We constructed a retrospective matched cohort using a 5% nationally representative sample of Medicare beneficiaries between 1996 and 2015. People with incident HIV diagnoses were individually matched to up to three controls based on demographics. Cox proportional hazards models adjusted for baseline demographics and comorbidities were used to assess the effect of HIV status on survival among four disabled groups by sex strata. Within each stratum, interactions between comorbidity variables and HIV status were examined. RESULTS: People with HIV, especially older women, had a higher prevalence of baseline comorbidities than controls. HIV--mortality association varied according to sex in older adults (Pâ=â0.004). Comorbidity--HIV interactions were more pronounced in disabled groups (Pâ<â0.0001). People with HIV with more chronic conditions had a less pronounced increase in the risk of death than those with fewer conditions, compared with uninfected controls. CONCLUSION: Medicare enrollees with newly diagnosed HIV had more prevalent baseline comorbidities and were at higher risk of death than people without HIV. HIV infection has a more pronounced effect among those with fewer comorbidities. Sex differences in HIV--mortality association exist among older Medicare enrollees.

BACKGROUND: A postpartum human papillomavirus vaccination program was locally implemented to address low initiation rates among young adults. Within 20 months, the program achieved high vaccine initiation and series completion rates. Based on the program's success, it was expanded to all 36 counties served by a public hospital. OBJECTIVE: This study aimed to conduct a quantitative and qualitative evaluation to examine the success and limitations of the program when expanded from 1 county to 36 counties, many of which are home to rural and medically underserved communities. STUDY DESIGN: Patient navigators reviewed the electronic medical records and immunization registry records of women aged ≤26 years, who delivered an infant at the public hospital, to determine whether they needed to initiate or complete the human papillomavirus vaccine series. Eligible women were counseled and offered the human papillomavirus vaccine during their hospital stay. Patient navigators scheduled follow-up injections in addition to the mother's postpartum or her infant's well-child visits, made reminder phone calls, and rescheduled missed appointments. Descriptive statistics, including frequencies and proportions, were used for patients approached in the initial and expansion programs. Frequencies from the initial and expansion programs were examined separately. Qualitative interviews were conducted with the clinic staff to evaluate the program. The qualitative analyses were conducted using NVivo (QSR International, Melbourne, Australia, version 10). RESULTS: Both initial and expanded programs achieved vaccine completion rates above 70%. Of the 2631 eligible postpartum women enrolled in the initial program, 785 (30%) had already been fully vaccinated. Of the remaining 1846 women, 1265 (69%) women received their first dose, and 196 (11%) women received their second or third dose on the postpartum unit. Of the 1461 women who received at least 1 dose through the initial program, 1124 (77%) completed all 3 doses. Of the 4330 eligible postpartum women enrolled in the expanded program, 886 (21%) had already been fully vaccinated. Of the remaining 3444 women, 2284 (66%) received their first dose, and 343 (10%) received their second or third dose on the postpartum unit. Of the 2627 women receiving at least 1 dose through the expanded program, 1932 (74%) completed all 3 doses. Clinic staff interviewed felt the program benefited the postpartum unit and clinics, because it increased patient knowledge of the vaccine, increased patient volume for vaccination, and gave healthcare providers more time to focus on other tasks. CONCLUSION: Human papillomavirus vaccination on the postpartum unit is an effective way to increase catchup rates and is well accepted by healthcare providers. High completion rates can be achieved if adequate support is provided, even among patients residing in rural or underserved areas who need extensive support to access primary healthcare services. Although this particular program may be considered costly, it is overall effective because the vaccine prevents 5 different types of cancer in women. The inclusion of human papillomavirus vaccination in routine postpartum care is a relatively easy way to reach many adults not vaccinated at a younger age and could help address low vaccination rates among young women in the United States, including hard-to-reach populations.

BACKGROUND: Human papillomavirus (HPV) vaccination has occurred unequally across the United States, potentially contributing to uneven vaccine-type HPV prevalence between regions. We examined whether emerging vaccine-related herd protection exhibits regional differences among unvaccinated girls and women. METHODS: We evaluated the prevalence of vaginal HPV among women 14-59 years of age from 2003 to 2014 using repeated cross-sectional data from the National Health and Nutrition Examination Survey (NHANES). Women who provided an adequate vaginal swab sample were included. Vaginal prevalence of vaccine-type HPV (types 6, 11, 16, 18) were examined in four regions of the United States between 2003 and 2014. We examined vaccine-type HPV prevalence in 2007-2014 in each US census region among younger participants (14-34 years old) stratified by vaccination status to determine whether one or both groups contributed to uneven HPV prevalence. RESULTS: A total of 12 175 participants 14-59 years of age met inclusion criteria. Vaccine-type HPV prevalence decreased in all regions. Vaccine-type HPV varied by region only among unvaccinated 14-34 year olds, with a higher prevalence in the Midwest (13.8%, 95% confidence interval (CI): 10.7-17.0) and South (12.5%, 95% CI: 10.2-14.8) compared to the Northeast (8.9%, 95% CI: 6.5-11.2). No regional variation in vaccine-type HPV prevalence was observed among vaccinated participants. CONCLUSIONS: Higher prevalence of vaccine-type HPV among unvaccinated women in the South and Midwest may contribute to regional disparities in HPV-related cancer incidence, as emerging herd immunity may not be as strong in those regions.

Tetanus, diphtheria, and acellular pertussis (Tdap) vaccination and influenza vaccination are recommended during pregnancy primarily to prevent influenza and pertussis in mothers and their infants. This study examines associations between prenatal Tdap vaccination and influenza vaccination of mothers and hepatitis B vaccination of their infants. A retrospective cohort study was conducted using data from electronic medical records from 15,468 deliveries to 14,925 mothers occurring April 2, 2014-December 3, 2016 at a university hospital in Texas. Hepatitis B vaccine receipt in the first 3â¯days of life was dichotomized. Margins post-estimation commands in Stata SE 15.1 were used to obtain predicted probabilities and risk differences after estimating odds ratios in logistic regression with robust variance estimates. Adjusted models included maternal age, race/ethnicity, Medicaid use, year of delivery, parity, and gravidity. Infants of mothers who received prenatal influenza vaccination in the 2014-2015 and 2015-2016 influenza seasons were more likely than those of mothers who did not to receive a hepatitis B vaccine in their first 3â¯days of life (adjusted risk difference (RD) 2.8%, 95% confidence interval (CI) 1.5-4.1% and RD 2.2%, 95% CI 0.9-3.5%, respectively). Hepatitis B vaccination was also higher among infants of Tdap-eligible mothers who received prenatal Tdap vaccination during pregnancy compared to those of mothers who did not (adjusted RD 9.1%, 95% CI 7.6-10.5%). Overall, prenatal vaccination was significantly associated with uptake of infant hepatitis B vaccine.

BACKGROUND: Human papillomavirus (HPV) vaccination is expected to reduce HPV-related disease and cancer in the US. However, many parents are hesitant to obtain the vaccine for their children. The purpose of this study is to examine how the reasons for refusing the HPV vaccine vary across regions of the US, across time, and by race/ethnicity. METHODS: This study used data on 13-17â¯year old adolescents collected by the National Immunization Survey - Teen (NIS-Teen) annually between 2008 and 2016. We evaluated the frequencies of parents who did not intend to vaccinate their children in the next year among unvaccinated children. Among these non-intenders, we evaluated how reasons for HPV vaccine hesitancy changed across time, by region of the US, and race/ethnicity. RESULTS: The proportion of non-intenders among unvaccinated decreased from 72% in 2010 to 58% in 2016. The most frequent reason for vaccine hesitancy was that parents felt HPV vaccination was not necessary (22.4%), followed by lack of provider recommendation (16.2%), and lack of knowledge (15.6%). Lack of provider recommendation increased in frequency as a reason for HPV vaccine hesitancy until 2012, then decreased in frequency through 2016. Cost was one reason that was elevated in all regions compared to the Northeast. Black non-intenders were less likely to report safety, costs, or their children's fear as reasons for not intending to vaccinate their children compared to white non-intenders. Hispanic non-intenders were more likely to report lack of knowledge and that the vaccine is not a school requirement as reasons not to vaccinate their children compared to white non-intenders. CONCLUSIONS: National advocacy for improving provider recommendation for HPV vaccination likely contributed to a sharp decline in HPV vaccine hesitancy due to lack of provider recommendation. Results indicate the need for multifaceted interventions to increase HPV vaccination.

BACKGROUND: Low human papillomavirus (HPV) vaccination rates early after introduction, particularly among low income and minority adolescents, may have resulted in disparities in vaccine-type HPV prevalence (types 6, 11, 16, 18). The purpose of this study was to examine racial/ethnic variations in HPV prevalence, and evaluate how HPV vaccination has affected vaccine-type HPV prevalence across time. METHODS: This study was a retrospective analysis of 6 cycles of the National Health and Nutrition Examination Survey (NHANES) data (2003-2014). Results on HPV status from vaginal samples of 14-26â¯year old females who responded about HPV vaccination were used to determine HPV prevalence. Prevaccine HPV prevalence was compared to post-licensure prevalence. Racial/ethnic comparisons were made across time, and models were developed to examine the role of HPV vaccination in observed variations for vaccine-type HPV prevalence. RESULTS: Among 4080 females, 29.7% were black, 25.6% were Mexican American, 8.9% were Hispanic, and 35.8% were white. Compared to prevaccine years (2003-2006), vaccine-type HPV did not decrease until late post-licensure years (2011-2014; 14.2% vs. 5.2%, pâ¯<â¯0.001). Most of the decrease occurred among white females between prevaccine and late post-licensure periods (15.2% vs. 4.1%, pâ¯<â¯0.001). Although a decrease in prevalence was observed among black females during the same periods (16.9% vs. 9.8%, pâ¯<â¯0.05), it was not as large as among white females. Prevalence decreased among Mexican Americans (8.2 vs. 4.0, pâ¯>â¯0.05) during the same periods, but the difference was not significant. Interactions between race and time were significant (pâ¯<â¯0.001), with uneven vaccination between black and white females contributing to the disparities observed. CONCLUSIONS: HPV vaccination was low in among black and Mexican American females, which contributed to disparities in HPV prevalence. Increasing vaccination among all adolescents, particularly 11-12â¯year olds, is important because most children this age will not have been exposed.

INTRODUCTION: Human papillomavirus vaccination is less prevalent among foreign-born than U.S.-born women and may lead to disparities in human papillomavirus-related cancers in the future. There is limited research on factors associated with vaccination uptake between these two groups. This study examined the association between place of birth and human papillomavirus vaccine uptake, and what determinants of vaccination attenuate this relationship. METHODS: The 2013-2015 National Health Interview Survey data on women was analyzed in 2016, to determine differences in prevalence of human papillomavirus vaccination between foreign- and U.S.-born women. Multivariate binary logistic regression analysis was used to examine the association between foreign-born status and human papillomavirus vaccine initiation, after controlling for health insurance status, having a usual source of care, obstetrician/gynecologist visits, Pap tests, length of U.S. residency, and citizenship. RESULTS: Human papillomavirus vaccination prevalence varied significantly among women born in different regions of the world. European and South-American women had the highest vaccination rates among all foreign-born women. Compared with U.S.-born women, foreign-born women were significantly less likely to report human papillomavirus vaccine initiation. This relationship was partially attenuated after adjusting for the covariates. Among foreign-born women, Asians were significantly less likely to report human papillomavirus vaccination uptake than white women. Additionally, living in the U.S. for >5 years was significantly associated with vaccine initiation, but attenuated by U.S. citizenship status. CONCLUSIONS: Public health interventions to improve human papillomavirus vaccination need to be developed to address multicultural audiences with limited access to health insurance and health care.

INTRODUCTION: BRCA mutation testing has been used for screening women at high risk of breast and ovarian cancer and for selecting the best treatment for those with breast cancer. To optimize the infrastructure and medical resources allocation for genetic testing, it is important to understand the use of BRCA mutation testing in the U.S. health system. METHODS: This retrospective cohort study included 53,254 adult women with insurance claims for BRCA mutation testing between 2004 and 2014 from ClinformaticsTM Data Mart Database. Data analysis was performed in 2016. This study assessed trends in the use of BRCA mutation testing in women with previously diagnosed breast or ovarian cancer and those without (unaffected women). RESULTS: Between 2004 and 2014, of those receiving BRCA testing, the proportion of BRCA tests performed in unaffected women increased significantly (p<0.001), from 24.3% in 2004 to 61.5% in 2014. An increase in the proportion of BRCA tests used in unaffected women was found in each characteristic subgroup. In 2014, most subgroups had a proportion surpassing 50%, except for those aged 51-65 years and those without a family history of breast cancer. There was a much lower proportion of those aged 20-40 years among tested women with previously diagnosed breast or ovarian cancer than in unaffected women (17.6% vs 41.7%, p<0.001). CONCLUSIONS: During the past decade, the role of BRCA testing has gradually shifted from being used primarily in cancer patients to being used in unaffected women in the U.S.

STUDY OBJECTIVE: To determine trends in characteristics associated with contraceptive use at coitarche from 1995 to 2006-2010. METHODS: The National Survey of Family Growth (NSFG) 1995 and 2006-2010 databases were used to abstract variables of interest. Generalized linear models (GLM) were applied to examine the association between the use of contraceptive methods at coitarche and variables abstracted for each database. RESULTS: Of the 9599 women from the 1995 database included in this study, 3885 (40%) used contraception at coitarche in comparison to 4860 (82%) out of 5931 women assessed in 2006-2010. For both time periods, Hispanic women were significantly less likely to use contraception at coitarche when compared to White women. In the 1995 database, only women from families with incomes >$50,000 were more likely to use contraception at coitarche, while women from families with income > $20,000 were more likely to use contraception at coitarche in 2006-2010. There were some differences noted in the association between age at coitarche and contraception use at coitarche, but in general, women who had a higher age at coitarche were more likely to use contraception. For both time periods, women were more likely to use contraception at coitarche if they used barrier methods as their first form of contraception or if they obtained their first contraceptive method from a spouse, partner, or friend. CONCLUSIONS: Our results suggest that access to contraception may be associated with use of a contraceptive method at coitarche. Innovative measures need to be investigated so that this young population has increased access to more reliable methods before their first sexual experience.

STUDY OBJECTIVE: To determine demographical and behavioral characteristics associated with contraceptive use at coitarche, or first sexual experience, to determine which populations are at greatest risk of contraceptive nonuse during early sexual experiences. DESIGN: Cross-sectional study. METHODS: We used the National Survey of Family Growth 2006-2010 database to abstract pertinent variables, including race, highest education, annual family income, parental living situation, importance of religion, age at coitarche, number of sexual partners, type of first contraception, and source of first contraception. Generalized linear models with logit link and binomial distribution were applied to examine the association between use of contraceptive methods at coitarche and the variables abstracted. RESULTS: Of the 5931 female participants included in the study, 1071 (18%) did not use contraceptive methods at coitarche. Only 199 (2%) of the female participants included in this study used the more reliable hormonal contraceptive methods at coitarche. Black females were significantly more likely than white females to use contraceptive methods at coitarche (p < 0.01). Females who initiated coitarche from 16 to 20 years of age were significantly more likely to use contraception at coitarche than females who had their first sexual experience at less than 16 years of age (p < 0.001). Females with greater educational background and greater family income were also significantly more likely to use contraception at coitarche (p < 0.001). Finally, females who obtained their first contraceptive methods from a spouse, partner, or friend were more likely to use contraception at coitarche than females who obtained their first method from a medical facility (p < 0.001). CONCLUSIONS: This study highlights several key differences between females who use contraceptive methods at coitarche versus those who do not. Greater effort needs to be focused on increasing access to more reliable contraceptive methods for young females, as females who obtain methods from nonmedical facilities are more likely to use contraceptive methods at coitarche.

OBJECTIVE: To examine the association between mother-child communication about sex, sexually transmitted diseases (STDs), and contraception/condoms and HPV vaccine uptake by gender. METHODS: Women (n = 1372) with ≥ 1 child aged 9-17 years receiving care in reproductive health clinics in Southeast Texas were asked to complete a self-administered questionnaire between September 2011 and October 2013. RESULTS: The majority of mothers with ≥ 1 eligible daughter (n = 886) reported having talked about 'sex' (77.7%), 'STDs' (76.6%) and 'contraception' (73.2%) with their daughters. The respective figures for mothers with ≥ 1 son (n = 836) were 68.8%, 69.0% and 65.3%. Mothers who discussed sex, STDs, or contraception with their daughters compared to those who did not were more likely to report that their daughter initiated (≥ 1 dose) HPV vaccination after adjusting for confounders (all p < .05). Similarly, mother-son discussions about STDs or condoms, but not sex, were associated with HPV vaccine initiation for their sons compared to those who did not discuss these topics. These associations were not significant with regard to HPV vaccine completion (3 doses) for neither daughters nor sons. CONCLUSION: Mother-child communication on STDs and contraception/condoms is associated with HPV vaccine initiation, but not completion, among both daughters and sons.

BACKGROUND: The objective of our study was to determine demographic characteristics, health and sexual behaviors, and psychological health associated with pregnancy ambivalence. We used a cross-sectional design for our study. METHODS: A self-administered cross-sectional survey was conducted among nonpregnant women 16-40 years old from southeast Texas from July 2010 to August 2011. The survey included questions pertaining to demographics, pregnancy intentions, health behaviors, sexual behaviors, violence exposure, pregnancy coercion, and psychological behaviors. Multivariate logistic regression analyses were performed to determine differences between ambivalent and nonambivalent females. RESULTS: Of the 1,388 women included in this analysis, 529 (38%) were ambivalent toward pregnancy. Ambivalent women were younger (p=0.03), had fewer children living at home (p<0.01), and were less likely to have been previously pregnant (p=0.01). Multivariate analysis showed that ambivalent women were more likely to smoke (p<0.01), sleep poorly (p=0.02), have had more sexual partners in the past month (p<0.01) and in their lifetime (p=0.01), not used contraception at last sex (p=0.01), be a victim of violence (p=0.01), and have experienced pregnancy coercion (p<0.01). In addition, these women exhibited higher scores on scales measuring depressive symptoms (p=0.01) and perceived stress (p<0.01). CONCLUSIONS: Women ambivalent toward pregnancy are not only less likely to use contraception but also more likely to have unhealthy behaviors and psychological risk factors. As this combination of characteristics may put a future pregnancy and child at risk, awareness about the possible consequences of pregnancy ambivalence needs to increase among the public and medical community. Providers need to focus efforts on screening for this patient population and preventive education through contraceptive counseling.

BACKGROUND: Prior studies have not examined the role of psychosocial stress in the relationship between poor sleep quality and obesity among women of lower socioeconomic status (SES). We tested the following hypotheses in a sample of reproductive-age women of lower SES: 1) Poor sleep quality is related to increased risk of obesity, and 2) psychosocial stress confounds this association between poor sleep quality and obesity. METHODS: A total of 927 women age 16 to 40 years attending public health clinics in Southeastern Texas provided information on the Pittsburgh Sleep Quality Index and sociodemographic and health characteristics, including the Perceived Stress Scale. Height, weight, and waist circumference (WC) were measured in clinic. A series of models examined the associations between sleep disturbance, perceived stress, and weight outcomes, accounting for potential confounding factors. RESULTS: Nearly 30% of women were overweight, and 35% were obese. Half of women had a WC of greater than 35 inches. Most women had poor sleep quality and high levels of stress. Sleep quality and perceived stress were not related to body mass index category or WC in models that adjusted for age and race/ethnicity. Adjusting for potential confounding factors did not alter results. Perceived stress did not modify the association between sleep quality and weight outcomes. CONCLUSIONS: Poor sleep quality and psychosocial stress were not related to weight in reproductive-aged women of lower SES. However, poor sleep quality, high stress, overweight, and obesity were common in this group.

OBJECTIVE: Many U.S. health care providers remain reluctant to prescribe intrauterine devices (IUDs) to teenagers as a result of concerns about serious complications. This study examined whether 15-19-year-old IUD users were more likely to experience complications, failure, or early discontinuation than adult users aged 20-24 years and 25-44 years and whether there were differences in these outcomes between users of levonorgestrel-releasing intrauterine systems and copper IUDs. METHODS: A retrospective cohort study was conducted using health insurance claims obtained from a private insurance company of 90,489 women who had an IUD inserted between 2002 and 2009. Logistic regression models were used to estimate the odds of experiencing complications, method failure, or early discontinuation within 12 months of insertion by age group and type of IUD inserted. RESULTS: Serious complications, including ectopic pregnancy and pelvic inflammatory disease, occurred in less than 1% of patients regardless of age or IUD type. Women aged 15-19 years were more likely than those aged 25-44 years to have a claim for dysmenorrhea (odds ratio [OR] 1.4, confidence interval [CI] 1.1-1.6), amenorrhea (OR 1.3, CI 1.1-1.5), or normal pregnancy (OR 1.4, CI 1.1-1.8). Overall, early discontinuation did not differ between teenagers and women aged 25-44 years (13% compared with 11%, P>.05). However, use of the levonorgestrel-releasing intrauterine system was associated with fewer complications and less early discontinuation than the copper IUD in all age groups. CONCLUSIONS: The IUD is as appropriate for teenagers to use as it is for older women, with serious complications occurring infrequently in all groups. The levonorgestrel-releasing intrauterine system may be a better choice than the copper IUD as a result of lower odds of complications, discontinuation, and failure. LEVEL OF EVIDENCE: II.
