One dose versus two doses of COVID-19 vaccine for the prevention of breakthrough infections among people previously infected with SARS-Cov-2.

Studies have suggested the effectiveness of COVID-19 vaccines in preventing SARS-CoV-2 reinfection among those previously infected. However, it is not yet clear if one dose of the vaccine is enough to prevent breakthrough infections compared to two doses. Using data from Optum deidentified COVID-19 Electronic Health Record (EHR) data set, we assessed breakthrough infection risks in individuals previously infected, comparing those with one vaccine dose to those with two doses. Propensity scores were applied to mitigate confounding factors. Follow-up spanned 6 months, beginning 2 weeks postvaccination. Among 213 845 individuals, those receiving one vaccine dose had a significantly higher breakthrough infection risk than the two-dose group (HR 1.69, 95% CI 1.54-1.85). This pattern was observed across genders, racial/ethnic groups, age categories, and vaccine types. This study reveals a substantial disparity in the risk of breakthrough infections between individuals receiving one versus two doses of the COVID-19 vaccine, suggesting that a single dose may not provide adequate protection against reinfection.

Assessing incident depression among older people with and without HIV in U.S.

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.

Prevalence of Oral Human Papillomavirus Infection: Impact of Sex, Race/Ethnicity, and Vaccination Status.

BACKGROUND: Prior studies have demonstrated differences in oral human papillomavirus (HPV) prevalence by sex and race/ethnicity. In this study, we examined the impact of vaccination on these disparities. METHODS: We examined participants aged 18-59 years in the National Health and Nutrition Examination Survey from 2011 to 2016 who reported their HPV vaccination status and submitted an adequate oral sample (N = 9437). Oral prevalence of HPV, grouped by any, low-risk, high-risk, 4 valent (4v) HPV, 9 valent (9v) HPV, and nonvaccine types, was examined by sex, race/ethnicity, and vaccination status. Binary logistic regression was used to estimate prevalence ratios by vaccination status. Multivariable logistic regression models controlled for age, sex, and race/ethnicity. RESULTS: The prevalence of any, nonvaccine, low-risk, high-risk, 4vHPV, and 9vHPV types was higher among males than females, even among vaccinated participants. Examination of racial/ethnic differences demonstrated differences in all HPV groups among unvaccinated males and among low-risk types in females. In all but the 2 vaccine-type groups, the prevalence of oral HPV was notably higher among Black males compared with other groups. Significant differences were not observed by race/ethnicity among vaccinated males or females. CONCLUSIONS: Males tested positive for oral HPV more frequently than females, even among those vaccinated. This may have resulted from a lower frequency of males being vaccinated before initiating oral sex than females. Vaccination of males at the recommended age, therefore, may decrease differences in oral HPV by sex. Racial/ethnic differences were observed only in unvaccinated individuals, suggesting these disparities will decrease as more individuals are vaccinated.

Impact assessment of a provider-targeted national vaccine messaging campaign on human papillomavirus vaccination rates among US adolescent males.

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.

Knowledge, Attitudes, Willingness to Pay, and Patient Preferences About Genetic Testing and Subsequent Risk Management for Cancer Prevention.

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.

Prevalence of Genital Human Papillomavirus by Age and Race/Ethnicity Among Males.

BACKGROUND: Genital and oral cancers are often caused by human papillomavirus (HPV) types that can be prevented through HPV vaccination. Since HPV is sexually transmitted, knowledge of penile prevalence of vaccine-type HPV among US males can help predict potential disparities in these cancers. This study examines penile HPV prevalence by age and race/ethnicity among males. METHODS: This study was a secondary analysis of publicly available data from the National Health and Nutrition Examination Survey (NHANES). Using data from penile swab samples collected from males between 2013 and 2016, the prevalence of 4vHPV and 9vHPV vaccine types was examined across age groups and by race/ethnicity. Logistic regression models adjusting for demographics, sexual behavior, and circumcision were examined to determine whether associations remained after accounting for confounders. RESULTS: Among 2548 males evaluated, HPV infection prevalence differed by race/ethnicity, with Black males exhibiting a higher prevalence of HPV. Examination of 4vHPV type prevalence by age group showed that 18-26-year-old males had a lower prevalence than older age groups. After controlling for confounders, 4vHPV prevalence was only significantly elevated among 27-34-year-old males, those who were single, and males with ≥3 lifetime sex partners. In adjusted models, 9vHPV type prevalence remained elevated among Black males compared with White males. CONCLUSIONS: Variations in 9vHPV type prevalence between Black and White individuals indicate future disparities in HPV-related genital cancers may continue in the United States during the next decade. Revaccinating certain populations with the 9vHPV vaccine may be appropriate to help mitigate this.

Quantitative and qualitative assessment of an all-inclusive postpartum human papillomavirus vaccination program.

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.

BRCA testing in unaffected young women in the United States, 2006-2017.

BACKGROUND: The discovery of the BRCA gene in the 1990s created an opportunity for individualized cancer prevention. BRCA testing in young women before cancer onset enables early detection of those with an increased cancer risk and creates an opportunity to offer lifesaving prophylactic procedures and medications. This study assessed trends in BRCA testing in women younger than 40 years without diagnosed breast or ovarian cancer (unaffected young women [UYW]) for cancer prevention between 2006 and 2017 in the United States. METHODS: This study included 93,278 adult women 18 to 65 years old with insurance claims for BRCA testing between 2006 and 2017 from the de-identified Optum Clinformatics Data Mart database. The data contained medical claims and administrative information from privately insured individuals in the United States. The proportion of BRCA testing in UYW younger than 40 years among adult women aged 18 to 65 years who received BRCA testing was assessed. RESULTS: In 2006, only 10.5% of the tests were performed in UYW. The proportion of BRCA tests performed in UYW increased significantly to 25.5% in 2017 (annual percentage change for the 2006-2017 period, 6.9; 95% confidence interval, 6.4-7.3; P < .001). The increased trend in the proportion of BRCA tests in UYW significantly differed by region of residence and family history of breast or ovarian cancer. CONCLUSIONS: Over the past decade, there was increased use of BRCA testing for cancer prevention. Additional efforts are needed to maximize the early detection of women with BRCA pathogenic variants so that these cancers may be prevented.

Adolescent use of combined hormonal contraception and peak bone mineral density accrual: A meta-analysis of international prospective controlled studies.

OBJECTIVE: Many women use combined hormonal contraceptives (CHC) during adolescence during which they are accruing peak areal bone mineral density (BMD) that relates to lifetime fracture risk. To build BMD requires formation with which CHC-related exogenous oestrogen may interfere. We compared peak BMD accrual in adolescents using and not using CHC. DESIGN/PARTICIPANTS: We performed literature searches for prospective published peer-reviewed articles providing 12- to 24-month BMD change in adolescent (12- to 19-year-old) women using CHC vs CHC-unexposed control women. METHODS: Meta-analyses used random-effects models to assess BMD change rate at lumbar spine (LS) and other sites in adolescent CHC users vs CHC nonusers. RESULTS: Literature searches yielded 84 publications of which nine were eligible. Adolescent-only data were sought from cohorts with wider age inclusions. The 12-month LS meta-analysis with eight paired comparisons in 1535 adolescents showed a weighted mean BMD difference of -0.02 (95% confidence interval [CI]: -0.05 to 0.00) g/cm2 in CHC-exposed adolescents (P = 0.04). The 24-month LS meta-analysis with five paired comparisons in 885 adolescents showed a highly significant weighted mean BMD difference of -0.02 (95% CI: -0.03 to -0.01) g/cm2 in CHC-exposed adolescents (P = 0.0006). Heterogeneities by I2 were 96% and 85%, respectively. Insufficient data for other bone sites precluded quantitative analysis. CONCLUSION: Given that adolescent exposure to CHC appears to be increasing, this evidence for potential impairment of peak spinal BMD accrual is of concern and suggests a potential public health problem. Randomized controlled trial data are needed to determine CHC effects on adolescent bone health.

Prenatal vaccination of mothers and hepatitis B vaccination of their infants.

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 3 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 3 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.

Trends in breast cancer mortality by stage at diagnosis among young women in the United States.

BACKGROUND: Assessing trends in breast cancer survival among young women who are largely unaffected by breast cancer screening will provide important information regarding improvements in the effectiveness of cancer care for breast cancer in the last few decades. METHODS: The cohort for this study consisted of women who were diagnosed with breast cancer between ages 20 and 39 years from the Surveillance, Epidemiology, and End Results program's 9-registry areas from 1975 to 2015. Trends in the breast cancer incidence rate and survival were assessed among young women. RESULTS: Among women aged 20 to 39 years, breast cancer incidence increased from 24.6 per 100,000 in 1975 to 31.7 per 100,000 in 2015 (annual percent change, 0.5; 95% confidence interval [CI], 0.4-0.6). Among women with breast cancer, 5-year breast-cancer-specific survival increased significantly from 74.0% during 1975 to 1979 to 88.5% during 2010 to 2015 (hazard ratio for dying from breast cancer for 2010-2015 vs 1975-1979, 0.37; 95% CI, 0.32-0.41). The increase in cancer-specific survival reached a plateau in 2005; however, among young women with metastatic breast cancer, it continued to increase after 2005, from 45.6% during 2005 to 2009 to 56.5% during 2010 to 2015 (hazard ratio for dying from breast cancer for 2010-2015 vs 2005-2009, 0.74; 95% CI, 0.60-0.92). Similar patterns also were observed for 5-year overall survival and among women aged 20 to 29 years and those aged 30 to 39 years. CONCLUSIONS: There were substantial improvements in the effectiveness of breast cancer treatment on overall and cancer-specific survival from 1975 to 2015. However, improvements appeared to have reached a plateau after 2005, except among young women with metastatic breast cancer, in whom survival continued to improve throughout the period.

Adherence to ACIP Recommendation for Human Papillomavirus Vaccine Among US Adolescent Girls.

The objective of this study was to examine correlates of human papillomavirus (HPV) vaccine use according to Advisory Committee on Immunization Practices (ACIP)'s recommendations among US adolescent girls. We used National Immunization Survey of Teens 2013 data. Based on provider-verified (n = 9403) information, 57.3, 39.1 and 19.0 % of adolescent girls, initiated, completed and completed the HPV vaccine according to ACIP's recommendation (by age 12), respectively. Hispanic race/ethnicity, a physician recommendation for HPV vaccine and ≥1 influenza vaccine in the past 3 years were all associated with a higher likelihood of compliance with ACIP's recommendation. Girls from a larger family and those whose immunization provider was a STD/school/teen clinic were less likely to receive the vaccine at the recommended age compared to a girl raised in a smaller sized family and received immunization from a hospital facility, respectively. Only one-fifth of 13-17 yo girls receive the HPV vaccine by age 12 as recommended by ACIP. Physician visits and influenza vaccination settings are opportunities to improve vaccine series completion at the recommended age.

Reduction in Vaccine-Type Human Papillomavirus Prevalence Among Women in the United States, 2009-2012.

Between 2009 and 2012, the proportion of young women in the United States completing the human papillomavirus (HPV) vaccine doubled. To understand how quickly this increased uptake is affecting women in the United States, we evaluated the prevalence of vaccine-type (VT) HPV strains among young women in national data sets from 2009-2010 and 2011-2012. Among 18-26-year-old women, the prevalence of VT HPV decreased markedly over a short interval, from 15.4% in 2009-2010 to 8.5% in 2011-2012 (prevalence ratio, 0.51; 95% confidence interval, .28-.92), and the prevalence of high-risk VT HPV decreased from 13.1% to 6.5% (0.46; .25-.86). Reductions in HPV-related diseases will probably follow.

A human papillomavirus vaccination program for low-income postpartum women.

BACKGROUND: Effective interventions are needed to address the low rate of human papillomavirus (HPV) vaccination in the United States, particularly among girls and women 16-26 years old. Counseling and offering the vaccine to postpartum patients could be an effective strategy to increase uptake among young women who did not complete the 3-dose series at an earlier age. OBJECTIVE: The purpose of this evaluation was to assess the effectiveness of a multicomponent program designed for postpartum women that used patient navigators (PNs) and reminders for follow-up visits to improve uptake and completion of the HPV vaccine series. STUDY DESIGN: As part of standard care, patients ≤26 years of age from Galveston County, Texas, who delivered an infant from November 2012 through June 2014 at a public hospital were counseled and offered the HPV vaccine postpartum. PNs assisted with scheduling follow-up injections during postpartum or well-child visits. A program evaluation was conducted after 20 months. RESULTS: Of 1038 patients approached, only 161 (15.5%) had previously completed the vaccine series. Of the 877 patients who had not completed the series, 661 (75.4%) received at least 1 dose postpartum, with 575 patients receiving their first dose and 86 receiving their second or third doses. By April 2015, initiation rates had increased as a result of this program from 25.4% before the program was initiated to 80.8% and completion rates from 15.5-65.1%. Missed appointments for injections were less likely among those who received text message reminders and more likely among those with ≥2 prior pregnancies. Those who were Hispanic or had received an influenza vaccination in the last year were more likely to initiate and complete the series through this program. Patients who missed ≥1 follow-up appointments were less likely to complete the vaccine series. CONCLUSION: Offering the HPV vaccine postpartum dramatically increased initiation rates among postpartum patients. PN and text messages ensured that a high percentage completed all 3 doses.

Effect of number of human papillomavirus vaccine doses on guideline adherent cervical cytology screening among 19-26year old females.

PURPOSE: Little is known about how the number of HPV vaccine doses affect adherence to screening guidelines. This study compared adherence to cervical cancer screening by the number of HPV vaccine doses received by young women and assessed whether the specialty of vaccinating providers affected behavior. METHODS: This retrospective cohort study using administrative insurance claims records included 24,964 19-26year old women who received at least 1 injection of the HPV vaccine between January 2006 and November 2009. Vaccinated young women continuously enrolled in a nationally-representative private insurance plan for 6months prior to and 37months after HPV vaccine administration were included. Logistic regression was used to compare the odds of Papanicolaou (Pap) testing 3years after vaccine initiation by number of vaccine doses and provider type. RESULTS: In this sample, 79.3% had a Pap test 3years following vaccine initiation. Receiving 1 (aOR: 0.60, 95% CI 0.55-0.65) or 2 (aOR: 0.80, 95% CI 0.74-0.87) doses was associated with decreased odds of Pap testing compared to 3 doses. Many young women in our sample (16.5%) were diagnosed with cervical dysplasia prior to HPV vaccination. Patients vaccinated by non-obstetrician/gynecologists were less likely to get a Pap test following vaccination. CONCLUSIONS: Women who received 1 or 2 doses of the HPV vaccine were less likely than those who received 3 doses to be screened for cervical cancer 3years following vaccine initiation. Pediatricians and primary care physicians should convey the importance of initiating and continuing screening to HPV vaccinated patients.

Implementation of a Postpartum HPV Vaccination Program in a Southeast Texas Hospital: A Qualitative Study Evaluating Health Care Provider Acceptance.

Introduction The objective of this qualitative study was to assess healthcare providers' acceptability of an ongoing postpartum human papillomavirus (HPV) vaccination program in Southeast Texas and its integration into everyday clinical care. Methods In 2012, the Department of Obstetrics & Gynecology at the University of Texas Medical Branch (UTMB) began offering HPV vaccination as part of standard postpartum care to increase vaccination rates among young women in Galveston County. Initial vaccine doses were offered on the postpartum unit while subsequent doses were coordinated with postpartum and well-baby visits. Thirty months after project initiation, semi-structured interviews of physicians (n = 12) and nurses (n = 6) involved in postpartum and pediatric care at UTMB were conducted. Interview transcripts were analyzed using thematic analysis in Nvivo10. Results Overall, providers demonstrated "pro-vaccine" attitudes and stated the program was an effective strategy for vaccinating hard-to-reach women. Cancer prevention was the main perceived benefit while follow-up compliance was the primary perceived patient barrier. The initial challenges with integrating postpartum HPV vaccination included miscommunication between providers regarding vaccine orders and coordination issues with well-baby visits for follow-up doses. One novel finding was providers' beliefs that women's personal HPV vaccine practices may positively impact their decisions about later vaccinating their children against HPV. Providers' suggestions to improve the program included: enhancing postpartum HPV vaccine education for patients, offering more continuing education for providers, and increasing community awareness of HPV vaccination. Discussion These findings can help providers of postpartum care understand how to integrate postpartum HPV vaccination into their current practices and how to overcome perceived vaccination barriers.

Differences in Women Who Choose Subdermal Implants Versus Intrauterine Devices.

Objective: To determine if there are any differences in the patient populations that choose subdermal implants versus intrauterine devices (IUDs) for contraceptive purposes. Study Design: Retrospective chart review. Electronic medical records of women who presented to the University of Texas Medical Branch in Galveston's Regional Maternal Child Health Program Clinics in southeast Texas from March 2011 to March 2013 and received a subdermal implant or IUD were reviewed. Differences in characteristics of women who chose either form of contraception were determined. Results: A total of 356 charts were reviewed. Of those, 188 (53%) women chose the subdermal implant and 168 (47%) chose an IUD. Patients who chose subdermal implants were more likely to have had a long-acting reversible contraceptive (LARC) method previously (p<0.01), previous vaginal deliveries (p<0.001), and an interval from delivery to LARC placement of >1 year (p<0.001). LARC choice was race-specific in that, when compared to Caucasian women, African-American women were significantly more likely to choose an IUD, while Hispanic women were significantly more likely to choose subdermal implants (p=0.002). Conclusion: Different populations choose subdermal implants versus IUDs for contraception. Further research is needed to determine etiologies for these differences.

Complications and continuation rates associated with 2 types of long-acting contraception.

OBJECTIVE: We sought to compare complication and continuation rates of the levonorgestrel intrauterine system (LNG-IUS) with the subdermal etonogestrel (ENG) implant across the United States among girls and women 15-44 years of age. STUDY DESIGN: A retrospective study of health insurance claims records from 2007 through 2011 identified a cohort of women who had LNG-IUS (n = 79,920) or ENG implants (n = 7374) inserted and had insurance coverage for 12 months postinsertion. Claims for complications were examined 12 months after insertion, or until removal of either device within each of 3 age groups. RESULTS: After its introduction in 2007, the frequency of ENG implants increased each year and almost a third of all insertions were in teenagers. However, among women ≤24 years old who had delivered an infant in the prior 8 weeks, a LNG-IUS was more likely to be inserted than an ENG implant (P < .05). The most frequent complications with both methods were related to abnormal menstruation, which was more likely to occur among ENG implant users. Overall, 83-88% of the entire sample used their chosen method for at least 12 months. The odds of continuation were similar for both methods among teenagers, but ENG implants were more likely to be removed prematurely among women 20-24 years old (odds ratio, 1.21; 95% confidence interval, 1.06-1.39) and 25-44 years old (odds ratio, 1.49; 95% confidence interval, 1.35-1.64). CONCLUSION: Both of these long-acting contraceptive methods are well tolerated among women of all ages, and demonstrate high continuation rates.

Association of frequent use of food labels with weight loss behaviors among low-income reproductive-age women.

OBJECTIVE: To examine whether frequent use of food labels is associated with weight loss behaviors among low-income reproductive-age women. METHODS: A self-administered survey of 1245 women aged 16 to 40 years assessed the frequency of food label use and weight loss behaviors during the past 12 months. Multivariate logistic regression analyses were performed to examine the association between frequent use of food labels and weight loss behaviors after adjusting for confounders. RESULTS: Overall, 10.4% to 19.6% of women frequently used food labels to obtain information on different sections (ingredient list, nutrient claims, nutrition panel, serving size, or health claims), dietary components (calories, total fat, saturated fat, cholesterol, sodium/salt, fiber, sugar, vitamins, or minerals), and food products (desserts, snacks, frozen dinners, cereals, salad dressings, table spreads, or raw/processed meat). Women who used food labels frequently were more likely to engage in healthy weight loss behaviors compared to those who used them infrequently or did not use them at all. For example, the odds ratios (OR) and 95% confidence interval (CI) of "began to exercise/exercised more" for the 3 categories of food label use mentioned above were 2.24 and 1.65-3.04; 2.52 and 1.90-3.32; and 1.85 and 1.36-2.52, respectively. The odds of healthy weight loss behaviors were 2 to 4 times higher when food labels were used frequently to seek information on calories and nutrients such as total fat, saturated fat, or cholesterol. However, frequent food label users were also more likely to practice a few unhealthy weight loss behaviors, such as taking diet pills, medicines, herbs, or supplements without a prescription. CONCLUSIONS: Frequent use of food labels was associated with increased healthy weight loss behaviors among reproductive-age women, which can be incorporated into obesity preventive strategies with distinct awareness regarding unhealthy weight loss behaviors.
