Human Papillomavirus-Associated Sexual Risks Among High School Students in the U.S.: Does Sexual Orientation Play a Role?

We examined the association between sexual orientation and human papillomavirus (HPV)-related risky sexual behaviors among high school students in the U.S. We used the 2015 Youth Risk Behavior Survey, a three-stage cluster sample, nationally representative, cross-sectional study. Participants were sexually active students (Grades 9-12) in public, private, and Catholic schools in 50 states and the District of Columbia (n = 5,958). Sexual orientation dimensions were: sexual self-identity (heterosexual, gay, lesbian, bisexual, and not sure) and sex of sexual contacts. HPV-associated risky sexual risk behaviors selected a priori were early sexual debut (≤ 12 or ≥ 13 years old) and number of lifetime partners (≥ 2 or ≥ 4). Separate multiple logistic regression analyses estimated association between sexual orientation and sex of sexual contacts, and HPV-associated risky sexual behaviors. Among the 5,958 high school students, a quarter had ≥ 4, and two-thirds had ≥ 2 sexual partners. Students who self-identified as bisexual (aOR = 2.43, 99% CI 1.19-4.98) or "not sure" (aOR = 4.56, 99% CI 2.54-8.17) were more likely to have sexual debut before 13 years. Similarly, students whose sexual contacts were adolescent females who had sex with females and males were more likely to have sexual debut before they turned 13 years of age (aOR = 3.46, 99% CI 1.83-6.48), or had ≥ 4 sexual partners (aOR = 2.66, 99% CI 1.74-4.08), or had ≥ 2 sexual partners (aOR = 3.09, 99% CI 1.91-5.00). In conclusion, HPV-associated risky sexual behavior is prevalent among high school students, especially sexual minorities. Interventions tailored to this population could increase HPV vaccine uptake and prevent future HPV-associated cancers and other negative outcomes.

Outcomes of pediatric low-grade gliomas treated with radiation therapy: a single-institution study.

Radiation therapy is often considered the treatment of choice for low-grade gliomas. However, given the long-term effects of radiation on the developing brain, the appropriate use of radiation therapy in pediatric patients remains controversial. The purpose of this study was to evaluate progression-free survival (PFS) of pediatric low-grade glioma patients treated with radiation therapy. Data were obtained through a retrospective chart review of patients treated between 1991 and 2008 from a single tertiary care center in the midwest. The study population consisted of 17 patients, of whom 8 (47%) had tumor recurrence after radiation therapy. The median follow-up time was 8.2 years, with a range of 2.3 to 17.2 years. The median age at diagnosis was 5.4 years, and the median age at radiation therapy was 9.4 years. The 3- and the 10-year PFS were 69%± 11.7% and 46%± 13.3%, respectively. A significant difference in PFS was seen when comparing brainstem tumors with hypothalamic/optic pathway tumors (P=0.019). Differences in PFS based on the age at diagnosis, the extent of initial surgery, and indication for radiation therapy were not significant. A larger multicenter study is needed to better assess PFS in these patients.

The effect of maternal body mass index on perinatal outcomes in women with diabetes.

OBJECTIVE: To determine the effect of increasing maternal obesity, including superobesity (body mass index [BMI] ≥ 50 kg/m2), on perinatal outcomes in women with diabetes. STUDY DESIGN: Retrospective cohort study of birth records for all live-born nonanomalous singleton infants ≥ 37 weeks' gestation born to Missouri residents with diabetes from 2000 to 2006. Women with either pregestational or gestational diabetes were included. RESULTS: There were 14,595 births to women with diabetes meeting study criteria, including 7,082 women with a BMI > 30 kg/m2 (48.5%). Compared with normal-weight women with diabetes, increasing BMI category, especially superobesity, was associated with a significantly increased risk for preeclampsia (adjusted relative risk [aRR] 3.6, 95% confidence interval [CI] 2.5, 5.2) and macrosomia (aRR 3.0, 95% CI 1.8, 5.40). The majority of nulliparous obese women with diabetes delivered via cesarean including 50.5% of obese, 61.4% of morbidly obese, and 69.8% of superobese women. The incidence of primary elective cesarean among nulliparous women with diabetes increased significantly with increasing maternal BMI with over 33% of morbidly obese and 39% of superobese women with diabetes delivering electively by cesarean. CONCLUSION: Increasing maternal obesity in women with diabetes is significantly associated with higher risks of perinatal complications, especially cesarean delivery.

Obesity trends and perinatal outcomes in black and white teenagers.

OBJECTIVE: Our objective was to explore the trends in prepregnancy body mass index (BMI) for black and white teenagers over time and the association between elevated BMI and outcomes based on race. STUDY DESIGN: This was a retrospective cohort study of singleton infants (n = 38,158) born to black (34%) and white (66%) teenagers (<18 years of age). We determined the prevalence of elevated prepregnancy BMI between 1993 and 2006 and the association between elevated prepregnancy BMI (primary exposure) and maternal and perinatal outcomes based on race (2000-2006). RESULTS: The percentage of white teenagers with elevated prepregnancy BMI increased significantly from 17-26%. White and black overweight and obese teenagers were more likely to have pregnancy-related hypertension than normal-weight teenagers; postpartum hemorrhage was increased only in obese black teenagers, and infant complications were increased only in overweight and obese white teenagers. CONCLUSION: Because the percentage of elevated prepregnancy BMI has increased in white teenagers, specific risks for poor maternal and perinatal outcomes in the overweight and obese teenagers varies by race.

Maternal superobesity and perinatal outcomes.

OBJECTIVE: The purpose of this study was to determine the effect of maternal superobesity (body mass index [BMI], ≥ 50 kg/m(2)) compared with morbid obesity (BMI, 40-49.9 kg/m(2)) or obesity (BMI, 30-39.9 kg/m(2)) on perinatal outcomes. STUDY DESIGN: We conducted a retrospective cohort study of birth records that were linked to hospital discharge data for all liveborn singleton term infants who were born to obese Missouri residents from 2000-2006. We excluded major congenital anomalies and women with diabetes mellitus or chronic hypertension. RESULTS: There were 64,272 births that met the study criteria, which included 1185 superobese mothers (1.8%). Superobese women were significantly more likely than obese women to have preeclampsia (adjusted relative risk [aRR], 1.7; 95% confidence interval [CI], 1.4-2.1), macrosomia (aRR, 1.8; 95% CI, 1.3-2.5), and cesarean delivery (aRR, 1.8; 95% CI, 1.5-2.1). Almost one-half of all superobese women (49.1%) delivered by cesarean section, and 33.8% of superobese nulliparous women underwent scheduled primary cesarean delivery. CONCLUSION: Women with a BMI of ≥ 50 kg/m(2) are at significantly increased risk for perinatal complications compared with obese women with a lower BMI.

Prevalence of atopic disorders and immunodeficiency in patients with ectodermal dysplasia syndromes.

BACKGROUND: Ectodermal dysplasia (ED) syndromes are a diverse group of disorders that affect multiple ectodermally derived tissues. Small studies and case reports suggest an increase in atopy and primary immunodeficiencies (PIDs) among patients with ED syndromes. OBJECTIVE: To determine the prevalence of clinical symptoms suggestive of atopy or immunodeficiency among a large cohort of children with ED syndromes. METHODS: A 9-page questionnaire was mailed to families who were members of the National Foundation for Ectodermal Dysplasias. The surveys were completed by parents of children younger than 18 years with a diagnosis of an ED syndrome or carrier state. Portions of the questionnaire were adapted from previously validated questionnaires developed by the International Study of Asthma and Allergies in Childhood (ISAAC). RESULTS: We received 347 completed questionnaires (41%). When compared with the 13- to 14-year-old children surveyed by ISAAC, we found both all-aged and age-matched children with ED syndromes, respectively, had significantly higher rates of asthma (32.2% and 37.2% vs 16.4%), rhinitis symptoms (76.1% and 78.3% vs 38.9%), and eczema (58.9% and 48.9% vs 8.2%). The prevalence of physician-diagnosed food allergies (20.7%) and PIDs (6.1%) in these ED patients also exceeded known rates in the general pediatric population. CONCLUSION: This large-scale, retrospective study demonstrates a greater reported prevalence of symptoms suggestive of atopic disorders and PIDs among children with ED syndromes than the general pediatric population. A combination of genetic and environmental factors in ED syndromes may contribute to breaches of skin and mucosal barriers, permitting enhanced transmission and sensitization to irritants, allergens, and pathogens.

Preterm delivery and age of SIDS death.

PURPOSE: The aim of the study is to (i) reexamine risk factors for sudden infant death syndrome (SIDS) and (ii) describe the relationship between length of gestation and age at death from SIDS. METHODS: To evaluate risk factors for SIDS, we used multivariable logistic regression and included maternal demographic characteristics, maternal health and behavioral factors, and infant characteristics, including fetal growth, using US national linked birth and death files from 1996 to 1998. We used multivariable linear regression with mean postnatal age of death as the outcome of interest, controlling for the factors listed (referent length of gestation, 40 to 41 weeks). RESULTS: The crude SIDS rate was 0.7 deaths/1000 live births (8199 deaths). Length of gestation was a strong risk factor for SIDS, with the adjusted odds ratio (OR) greatest at shorter gestations: 28 to 32 weeks (OR, 2.9; 95% confidence interval, 2.6-3.2). Infants with gestations of 22 to 27 and 28 to 32 weeks died at mean ages of 20.9 (SD = 0.8) and 15.3 (SD = 0.5) weeks, respectively (p < or = 0.002). Term infants (40 to 41 weeks) died of SIDS at an adjusted mean age of 14.5 (SD = 0.4) weeks. CONCLUSIONS: Preterm birth continues to be a strong risk factor for SIDS after controlling for fetal growth. With increasing gestational age, mean age of SIDS death decreases considerably, with the postnatal age of death of very preterm infants 6 weeks later than that of term infants.

Hearing screening at well-child visits.

OBJECTIVES: To determine hearing screening failure rates in primary care settings and to examine the referral practices in response to an abnormal screening test. METHODS: We enrolled a convenience sample of children between 3 and 19 years of age who were undergoing hearing screening during a well-child visit. A failure was defined as missing any frequency (1000, 2000, or 4000 Hz) in either ear at 20-dB hearing level. The pediatrician made the decision of whether to refer the patient for further evaluation. RESULTS: Three academic and 5 private practices enrolled 1061 children. Sixty-seven children (7%) were unable to complete the screening. Of the 948 children who completed the screen, a total of 852 children (90%) passed the screening and 96 children (10%) failed. After multivariable logistic regression analysis, the only statistically significant factor predictive of a failed screen was developmental delay (P = .02). Of the 96 children who failed the hearing screening, 57 (59%) had no further evaluation, 12 (13%) were rechecked, and 27 (28%) were referred. Similar percentages were seen with children who could not be screened. CONCLUSIONS: Although 10% of the children failed hearing screening, pediatricians neither rechecked nor referred more than half of these children. Screening that does not result in action for those failing the screening wastes resources and fails to properly identify hearing impairment in children.

Feasibility and Perception of Using Text Messages as an Adjunct Therapy for Low-Income, Minority Mothers With Postpartum Depression.

BACKGROUND: Postpartum depression (PPD) is the most common medical problem among new mothers that can have a negative impact on infant health. Traditional treatments are often difficult for low-income mothers to complete, particularly given the numerous barriers families face. OBJECTIVE: Among low-income, primarily racial, and ethnic minority mothers with postpartum depression, our aim was to evaluate (1) the feasibility of sending supportive text messages, and (2) the perception of receiving private, supportive text messages for postpartum depression. METHODS: Mothers found to be at risk for postpartum depression received supportive text messages four times weekly for 6 months in addition to receiving access to traditional counseling services based within an academic pediatric office. Feasibility was evaluated along with cellular and text messaging use, access, and perception of the message protocol. Perception of the message protocol was evaluated at study completion via a Likert scale questionnaire and open-ended qualitative survey. RESULTS: In total, 4158/4790 (86.81%) text messages were successfully delivered to 54 mothers over a 6-month period at a low cost (US $777.60). Among the 96 scripted messages, 37 unique messages (38.54%) allowed for a response. Of all sent messages that allowed for responses, 7.30% (118/1616) were responded to, and 66.1% of those responses requested a call back; 46% (25/54) of mothers responded at least once to a text message. Mothers felt that messages were easily received and read (25/28, 89%) and relevant to them personally (23/28, 82%). Most shared texts with others (21/28, 75%). CONCLUSIONS: Text messaging is feasible, well-accepted, and may serve as a simple, inexpensive adjunct therapy well-suited to cross socioeconomic boundaries and provide private support for at-risk mothers suffering from postpartum depression.

Racial disparities in pregnancy outcomes in obese women.

OBJECTIVE: To estimate the effect of race on perinatal outcomes in obese women. METHODS: Retrospective cohort study of birth records linked to hospital discharge data for all live born singleton infants ≥37 weeks gestation born to African-American or Caucasian Missouri residents from 2000 to 2006. We excluded major congenital anomalies and women with diabetes or chronic hypertension. Obesity was defined as pre-pregnancy body mass index ≥30 kg/m(2). RESULTS: There were 312 412 births meeting study criteria. 27.1% (11 776) of African-American mothers and 19.1% (49 415) of Caucasian mothers were obese. There were no differences in cesarean delivery or preeclampsia between obese African-American and obese Caucasian women. Infants of obese African-American women were significantly less likely to be macrosomic (0.9% vs. 2.2%, adjusted odds ratio [aOR] 0.5, 95% confidence interval [CI] 0.4 0.6) and more likely to be low birth weight (3.4% vs. 1.8%, aOR 1.9, 95% CI 1.7, 2.2) compared to infants of obese Caucasian women. Compared to their normal weight peers, obese Caucasian women had a greater relative risk of developing preeclampsia (aOR 3.1, 95% CI 2.9, 3.2) than obese African-American women (aOR 2.1, 95% CI 1.9, 2.4). CONCLUSION: Racial disparities impact obesity-related maternal and neonatal complications of pregnancy.

Effect of revised IOM weight gain guidelines on perinatal outcomes.

OBJECTIVE: We sought to examine perinatal outcomes in women with a body mass index (BMI) of 25 kg/m(2) comparing those whose weight gain met 2009 IOM guidelines to women meeting 1990 IOM guidelines. METHODS: This is a retrospective cohort study utilizing birth records linked to hospital discharge data for all term, singleton infants born to overweight, Missouri residents (2000-2006) with a BMI of 25 kg/m(2). We excluded congenital anomalies, mothers with diabetes, hypertension, or previous cesarean delivery. RESULTS: Fourteen thousand nine hundred fifty-five women gained 25-35 lbs (1990 guidelines); 1.6% delivered low birth weight (LBW) infants and 1.1% delivered macrosomic infants. Eight thousand three hundred fifty women gained 15-25 lbs (2009 guidelines); 3.4% delivered LBW infants and 0.6% delivered macrosomic infants. Women who gained 15-25 lbs were 1.99 (95% CI 1.67, 2.38) times more likely to have a LBW infant and 0.59 (95% CI 0.40, 0.76) times less likely to deliver a macrosomic infant. CONCLUSION: Limiting weight gain in women with a BMI of 25 kg/m(2), per the 2009 guidelines, increases the risk of LBW deliveries and decreases the risk of macrosomia but does not reduce associated adverse perinatal outcomes. Further studies should explore the optimal weight gain to reduce these outcomes.

Multiple psychiatric diagnoses common in privately insured children on atypical antipsychotics.

OBJECTIVE: To evaluate the prevalence of atypical antipsychotic use in privately insured children and the diagnoses associated with treatment. STUDY DESIGN: Claims were used to conduct a retrospective cohort study of children aged 2 through 18 years in the Midwest, covered by private insurance between 2002 and 2005 (n = 172,766). The 1-year prevalence of children receiving atypical antipsychotics was determined along with associated diagnoses. RESULTS: The 1-year prevalence of atypical antipsychotics ranged from 7.9 per 1000 in 2002 to 9.0 in 2005. The leading diagnoses were disruptive behavior disorders (67%), mood disorders (65%), and anxiety disorders (43%).The authors found that 75% of children on atypical antipsychotics had more than one psychiatric diagnosis. CONCLUSIONS: Atypical antipsychotic use is primarily seen in children who have multiple psychiatric diagnoses. Studies are needed to assess the long-term safety and effectiveness in such patients with multiple diagnoses.

Validity of pure-tone hearing screening at well-child visits.

OBJECTIVE: To estimate the sensitivity and specificity of pure-tone audiometry hearing screening in the primary care setting. DESIGN: Prospective cohort study. SETTING: Eight academic and private pediatric practices. PARTICIPANTS: A subset of children from a convenience sample of 1061 children between 3 and 19 years of age were screened for hearing loss using pure-tone audiometry. Intervention Formal audiologic evaluations (gold standard) for those children referred by their primary care physician (28 children) and for a random sample of children not referred (102 children). Main Exposure Pure-tone audiometry screening. MAIN OUTCOME MEASURES: Audiologic evaluations. RESULTS: A total of 28 children were referred to an audiologist for formal hearing testing after pure-tone audiometry screening during a well-child visit, at which 25 children did not pass the initial screening and 3 could not complete the screening. Of the 25 children, only 7 were evaluated by an audiologist, for a follow-up rate of 25%. One child was diagnosed as having hearing loss. Formal audiologic assessment was also performed on a random sample of 102 children who were not referred to the audiologist. For the random sample, hearing loss was identified in 2 of 76 (3%) children who passed and 1 of 16 (6%) children who did not pass pure tone audiometry screening. The sensitivity and specificity of pure-tone audiometry were 50% and 78%, respectively. CONCLUSION: In light of the increasing burden on physicians to provide preventive care, this study calls into question the value of hearing screening using pure-tone audiometry during well-child visits given the lack of follow-up after referral and the poor sensitivity.

Trends in the prevalence of chronic medication use in children: 2002-2005.

OBJECTIVE: Our goal was to estimate the quarterly prevalence of and evaluate trends for chronic medication use in children. PATIENTS AND METHODS: A cross-sectional study of ambulatory prescription claims data from 2002 to 2005 was conducted for a nationally representative sample of >3.5 million commercially insured children who were 5 to 19 years old. Prevalence of chronic medication use was measured quarterly for antihypertensives, antihyperlipidemics, type 2 antidiabetics, antidepressants, attention-deficit disorder and attention-deficit/hyperactivity disorder medications, and asthma-controller therapy. RESULTS: First-quarter 2002 baseline prevalence of chronic medication use per 1000 child beneficiaries ranged from a high of 29.5 for antiasthmatics to a low of 0.27 for antihyperlipidemics. Except for asthma medication use, prevalence rates were higher for older teens aged 15 to 19 years. During the study period, the prevalence rate for type 2 antidiabetic agents doubled, driven by 166% and 135% increases in prevalence among females aged 10 to 14 and 15 to 19 years, respectively. Therapy classes with double-digit growth in prevalence of use were asthma medications (46.5%), attention-deficit disorder and attention-deficit/hyperactivity disorder medications (40.4%), and antihyperlipidemics (15%). Prevalence of use growth was more moderate for antihypertensives and antidepressants (1.8%). Rates of growth were dramatically higher among girls than boys for type 2 antidiabetics (147% vs 39%), attention-deficit disorder and attention-deficit/hyperactivity disorder medications (63% vs 33%), and antidepressants (7% vs -4%). CONCLUSIONS: Prevalence of chronic medication use in children increased across all therapy classes evaluated. Additional study is needed into the factors influencing these trends, including growth in chronic disease risk factors, greater awareness and screening, and greater affinity toward early use of drug therapy in children.
