Epidemiology of cytomegalovirus infection in pregnancy in Israel: Real-world data from a large healthcare organization.

Congenital cytomegalovirus infection (cCMVi) is the leading cause of nonhereditary sensorineural hearing loss among newborns. Women newly acquiring cytomegalovirus infection (CMVi) during pregnancy have the highest risk of vertical transmission. This study aimed to describe the epidemiology of CMVi in pregnancy in a large healthcare database. A retrospective cohort study was performed using the Maccabi Healthcare Services database (Israel). Women aged 18-44 years old on July 1, 2013 with no record of pregnancy in the prior 6 months were followed through December 31, 2017 for first pregnancy occurrence. Pregnancy outcomes (live birth, spontaneous/therapeutic abortions, stillbirth, and uncertain outcomes) were captured. CMV test results were obtained to assess serostatus at the start of pregnancy (SoP) and primary CMV infection (CMVi) during pregnancy. Associations of demographic and reproductive factors with pCMVi were investigated (multivariable logistic regression). The study included 84 699 pregnant women (median age = 31 years; interquartile range = 28-35). Live birth, fetal loss, and uncertain pregnancy outcomes accounted for 76.8%, 18.2%, and 5.0%, respectively. The seroprevalence of CMV at the start of pregnancy in this cohort was 63.4% (95% confidence interval [CI]: 63.1-63.7). Among seronegative women with available test results (n = 10 657), CMVi incidence was 14.5 per 1000 (95% CI = 12.2-16.7). In multivariate logistic regression models adjusting for maternal age, CMVi was significantly associated with having one or more prior live births (odds ratio [OR]: 3.8 [95% CI: 2.6-5.4]) and having a child less than 6 years of age (OR: 4.3 [95%CI: 3.0-6.1]). One in three pregnant women in Israel is at risk for primary CMVi. This study demonstrates that real-world electronic healthcare data can be leveraged to support clinical management and development of interventions for congenital CMV by identifying women at high risk for CMVi during pregnancy.

Healthcare resource utilization and costs in 23-25-year-old women with human papillomavirus (HPV) associated anogenital diseases in Germany - a retrospective analysis of statutory health insurance claims data.

BACKGROUND: Human papilloma virus (HPV) causes multiple anogenital diseases including cervical cancer and is the most common sexually transmitted infection. Healthcare resource utilization (HRU) associated with HPV-related anogenital diseases includes diagnostic and disease specific treatment regimens. A recent study showed disease burden of young women aged 23-25 years, who were the first populations eligible to receive HPV vaccination after its introduction in Germany. Cost for the German statutory health insurance (SHI) due to HPV­related anogenital diseases in this population are unknown. This study aimed at assessing HRU and costs related to HPV-associated anogenital diseases for the Germany SHI. METHODS: We used a retrospective, matched cohort design to leverage the prior identified cohort of 23-25-year-old women born between 1989-1992 diagnosed with HPV-related anogenital disease from the Institute for Applied Health Research Berlin (InGef) Research Database. German SHI claims data from 2012-2017 were analyzed. The prior identified cases were matched (direct, without replacement) to women without anogenital diseases (1:10 ratio). HRU and costs for inpatient care, outpatient care, and pharmaceutical during a 3-year observation period were determined for both cases and controls and increments between the groups were assessed. RESULTS: 2,972 women diagnosed with anogenital diseases (cases) who were matched to 29,720 women without anogenital diseases (controls). Cases had more outpatient visits (52.4 visits vs. 39.2 visits) and more cases (45.2% vs. 31.7%) were hospitalized at least once in the 3­year observation period. Most common outpatient procedures performed in cases were conization of the cervix uteri (4.4% cases; n < 5 controls), followed by other excision and destruction of diseased tissue of the cervix uteri (3.1% in cases; 0.0% in controls). Median difference in total healthcare costs of €684 (mean difference: €1,089, 95%CI: €752-1,426) suggest that HPV-related anogenital diseases were responsible for approximately €3.2 Million more healthcare costs for the identified cases in the four birth cohorts within the 3­year observation period in the InGef Research Database. Costs were mainly driven by outpatient care (41.6% of total costs). CONCLUSION: In Germany, HPV-related anogenital diseases among young women are associated with considerable HRU and financial expenditures, mostly driven by outpatient care.

Burnout and the Sexual Assault Nurse Examiner: Who Is Experiencing Burnout and Why?

INTRODUCTION: A sexual assault nurse examiner role exemplifies the high-stress and highly emotional patient interactions that are often associated with burnout. The purpose of this study was to examine the frequency of burnout among sexual assault nurse examiners in North Carolina. METHODS: This cross-sectional study was an anonymous survey of practicing sexual assault nurse examiners within North Carolina using the Maslach Burnout Inventory and additional demographics. Results were analyzed with odds ratios, confidence intervals, Fisher exact, chi-square, and Kruskal Wallis tests as appropriate. RESULTS: Among 95 respondents, burnout was more frequent in sexual assault nurse examiners who stopped both emergency and nurse examiner work (55.6%, odds ratio 4.41, 95% confidence interval 1.07-18.06) and in dual function nurses (both emergency and nurse examiner work, 35.7%, odds ratio 2.71, 95% confidence interval 1.04-7.06). Sexual assault nurse examiners who had a high percentage of pediatric cases (above the median of 40%) were more likely to meet burnout thresholds for emotional exhaustion scores > 26 (48.78% vs 25.93%, χ2 = 5.30, P = .02) and more likely to meet burnout thresholds for depersonalization scores > 9 (48.78% vs 24.07%, χ2 = 6.28, P = .01). DISCUSSION: Higher frequency of burnout threshold criteria was found in those people who worked concurrently as a sexual assault nurse examiner and an emergency nurse and in those who had retired from both specialties. We also found that sexual assault nurse examiners with a higher case mix of pediatric cases had higher emotional exhaustion scores and higher depersonalization scores.

Genomic architecture and treatment outcome in pediatric acute myeloid leukemia: a Children's Oncology Group report.

Childhood acute myeloid leukemia (AML) is frequently characterized by chromosomal instability. Approximately 50% of patients have disease relapse, and novel prognostic markers are needed to improve risk stratification. We performed genome-wide genotyping in 446 pediatric patients with de novo AML enrolled in Children's Oncology Group (COG) studies AAML0531, AAML03P1, and CCG2961. Affymetrix and Illumina Omni 2.5 platforms were used to evaluate copy-number alterations (CNAs) and determine their associations with treatment outcome. Data from Affymetrix and Illumina studies were jointly analyzed with ASCAT and GISTIC software. An average of 1.14 somatically acquired CNAs per patient were observed. Novel reoccurring altered genomic regions were identified, and the presence of CNAs was found to be associated with decreased 3-year overall survival (OS), event-free survival (EFS), and relapse risk from the end of induction 1 (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.2-2.4; HR, 1.4; 95% CI, 1.0-1.8; and HR, 1.4; 95% CI, 1.0-2.0, respectively). Analyses by risk group demonstrated decreased OS and EFS in the standard-risk group only (HR, 1.9; 95% CI, 1.1-3.3 and HR, 1.7; 95% CI, 1.1-2.6, respectively). Additional studies are required to test the prognostic significance of CNA presence in disease relapse in patients with AML. COG studies AAML0531, AAML03P1, and CCG2961 were registered at www.clinicaltrials.gov as #NCT01407757, #NCT00070174, and #NCT00003790, respectively.

Associations of subjective social status with accelerometer-based physical activity and sedentary time among adolescents.

This study examined the associations of subjective social status (SSS) with physical activity (PA) and sedentary time (ST) among adolescents. The study population consisted of 420 Finnish adolescents aged 13 to 14 years. The adolescents reported their own SSS within their school (school SSS) and their family's social position within society (society SSS) based on the youth version of the Subjective Social Status Scale. Adolescents' moderate- to vigorous-intensity physical activity (MVPA) and ST were measured objectively by accelerometers and analyzed separately for the whole day and the school day. The associations between SSS and MVPA and ST outcomes were analyzed using multilevel modeling. School SSS was positively associated with whole-day MVPA and negatively associated with school-time ST. Society SSS was not significantly associated with objectively measured MVPA or ST. Both MVPA and ST are important behavioral determinants of health. As an important correlate of MVPA and ST, school SSS should be addressed by providers when discussing obesity risk and healthy behaviors with adolescents.

The Minneapolis-Manchester Quality of Life Instrument: reliability and validity of the Adult Form in cancer survivors.

PURPOSE: Childhood cancer survivors are at risk for deficits in health-related quality of life (HRQL) as they age. Youth (8-12 years) and adolescent (13-20 years) versions of the Minneapolis-Manchester Quality of Life Instrument (MMQL) have been developed to address survivor-specific issues and are currently in use; the MMQL-Adult Form has now been developed to assess HRQL in childhood cancer survivors aged 21-55 years. METHODS: The MMQL-Adult Form was administered to 499 adults: 65 cancer patients on-therapy, 107 off-therapy, and 327 healthy controls. Forty-four percent of patients were under 30 years old at cancer diagnosis. Principal components analysis was performed. We evaluated internal consistency reliability, stability (re-administration of the MMQL-Adult Form 2 weeks later), construct validity (concurrent administration of the SF-36), and known-groups validity (score comparisons across the three groups). RESULTS: Principal components analysis resulted in retention of 44 items across six scales: social functioning, physical functioning, cognitive functioning, outlook on life, body image, and psychological functioning. Internal consistency (Cronbach's α) was 0.80-0.90 for individual scales and 0.95 overall. Strong intraclass correlations (0.98 overall) indicated high stability. The MMQL-Adult Form distinguished between known groups; healthy controls scored better than patients on four of six scales. The MMQL-Adult Form scales correlated highly with similar SF-36 scales, demonstrating construct validity. CONCLUSIONS: The MMQL-Adult Form is a reliable and valid self-report instrument for measuring multidimensional HRQL in cancer survivors. Development of this instrument ensures availability of a tool enabling cross-sectional and longitudinal assessment of HRQL in childhood cancer survivors as they age.

The role of perceived discrimination during childhood and adolescence in understanding racial and socioeconomic influences on depression in young adulthood.

OBJECTIVE: To describe levels of perceived lifetime discrimination among young adults and determine its role in understanding this racial/ethnic disparity. STUDY DESIGN: Data were from the Princeton School District study, a 10-year cohort study in which investigators followed 545 non-Hispanic black (46%) and white initial 5-12 graders. Perceived lifetime racial discrimination was assessed with the General Ethnic Discrimination Scale and depressive symptoms with the Center for Epidemiological Studies Depression Scale. Stepped linear and logistic regression analyses assessed the relationships of race/ethnicity, parental education, and quintiles of discrimination to depressive symptoms. Stratification by race/ethnicity explored differences in the role of discrimination in explaining the relationship between parental education and depressive symptoms. RESULTS: Black students from professionally educated families had the greatest discrimination scores, 1.8 times greater than among their white peers (meanblack = 42.1 vs meanwhite = 22.8; P < .0001). Greater parental education was associated with lower depressive symptoms in all regression models. Race/ethnicity became predictive of depressive symptoms only after adjusting for discrimination, which was strongly associated with depressive symptoms. Stratified analysis suggested discrimination accounted for the relationship of parental education to depressive symptoms among whites. Among black subjects, accounting for discrimination unmasked a buffering effect of parental education. CONCLUSIONS: Greater levels of parent education are protective against depression for white youth. However, for black youth, greater parent education confers both risk and protective effects. The high discrimination among black youth from families with college or professionally educated parents overwhelms the protective effect of greater levels of parent education.

An 8-Year Prospective Study of Depressive Symptoms and Change in Insulin From Adolescence to Young Adulthood.

OBJECTIVE: To evaluate whether depressive symptoms predict change in fasting insulin among adolescents followed into young adulthood. We hypothesized that higher depressive symptoms would predict increased insulin and that puberty and race/ethnicity would moderate this relationship. METHODS: Data came from the Princeton School District Study, a school-based longitudinal cohort of non-Hispanic black and white adolescents (2001-2011). Depressive symptoms, fasting insulin, and body mass index were measured at baseline (adolescence) and 8 years later (young adulthood) in 685 participants. Puberty was assessed using a validated protocol measuring sex steroids and physical changes. The primary outcome was change in fasting insulin. Analyses accounted for age, sex, race, parental education, baseline insulin, body mass index z score, puberty, and time to follow-up. RESULTS: At baseline, depressive symptoms were correlated with insulin (ρ = 0.13, p = .001). High baseline insulin predicted insulin change (B = -11.50, standard error [SE] = 2.30, p < .001). Depressive symptoms also predicted insulin change, but only for pubertal adolescents (B = -0.23, SE = 0.11, p = .038). This relationship was moderated by race (p = .047); depressive symptoms predicted insulin change only among pubertal black adolescents (p = .030), not white (p = .49), and in the direction opposite that hypothesized (Bblacks = -0.51, SE = 0.23). Post hoc analyses revealed that pubertal black adolescents with high depressive symptoms had the highest baseline insulin, which stayed high across the follow-up period. CONCLUSIONS: Among pubertal black adolescents, elevated depressive symptoms are associated with increased risk for sustained hyperinsulinemia from adolescence into adulthood. These youths may be particularly vulnerable for Type 2 diabetes.

Sugar-Sweetened Beverage Intake Is Positively Associated with Baseline Triglyceride Concentrations, and Changes in Intake Are Inversely Associated with Changes in HDL Cholesterol over 12 Months in a Multi-Ethnic Sample of Children.

BACKGROUND: Intake of sugar-sweetened beverages (SSBs) is linked to greater cardiometabolic risk in adults. Although longitudinal evidence is sparse among children, SSB intake reduction is targeted to reduce cardiometabolic risk factors in this group. OBJECTIVE: We investigated characteristics associated with consumption of SSBs in a multi-ethnic sample of children/adolescents and measured cross-sectional and longitudinal associations between SSB intake and plasma HDL cholesterol and triglycerides (TGs) over 12 mo. METHODS: In a diverse cohort of children aged 8-15 y, cross-sectional associations (n = 613) between baseline SSB intake and blood lipid concentrations and longitudinal associations (n = 380) between mean SSB intake, changes in SSB intake, and lipid changes over 12 mo were assessed with multivariable linear regression. RESULTS: Greater SSB intake was associated with lower socioeconomic status, higher total energy intake, lower fruit/vegetable intake, and more sedentary time. In cross-sectional analysis, greater SSB intake was associated with higher plasma TG concentrations among consumers (62.4, 65.3, and 71.6 mg/dL in children who consumed >0 but <2, ≥2 but <7, and ≥7 servings/wk, respectively; P-trend: 0.03); plasma HDL cholesterol showed no cross-sectional association. In the longitudinal analysis, mean SSB intake over 12 mo was not associated with lipid changes; however, the 12-mo increase in plasma HDL-cholesterol concentration was greater among children who decreased their intake by ≥1 serving/wk (4.6 ± 0.8 mg/dL) compared with children whose intake stayed the same (2.0 ± 0.8 mg/dL) or increased (1.5 ± 0.8 mg/dL; P = 0.02). CONCLUSIONS: In a multi-ethnic sample of children, intake of SSBs was positively associated with TG concentrations among consumers, and changes in SSB intake were inversely associated with HDL cholesterol concentration changes over 12 mo. Further research in large diverse samples of children is needed to study the public health implications of reducing SSB intake among children of different racial/ethnic groups. The Daily D Health Study was registered at clinicaltrials.gov as NCT01537809.

Recruitment and retention of urban schoolchildren into a randomized double-blind vitamin D supplementation trial.

BACKGROUND: While rarely used for supplementation trials in the United States, schools present a practical alternative to a clinical setting. PURPOSE: We describe the successful recruitment and retention of urban schoolchildren into a 6-month randomized, double-blind vitamin D3 supplementation trial. METHODS: Boston-area urban schoolchildren, aged 8-15 years, were recruited in 2011-2012 through classroom and auditorium presentations. Informed consent forms in five languages were sent home to parents. Retention methods included regular telephone calls and gift cards for completed study visits. RESULTS: In total, 691 schoolchildren enrolled. Their mean (standard deviation) age was 11.7 (1.4) years; 59% were racial/ethnic minorities and 68% qualified for free or reduced-price school meals. Multi-level, culturally sensitive, creative approaches contributed to success in recruitment and retention. Of 691 participants, 81% completed the 6-month intervention period. Reasons for attrition included missed appointments and fear of a blood draw. More children from households with higher incomes were retained than those from households with lower incomes (85% vs 79%, respectively, P = 0.04). LIMITATIONS: The need for three fasting blood draws over the 6-month supplementation period was a limiting factor in the recruitment and retention of children in this study. CONCLUSION: Recruitment of urban children into a school-based randomized controlled trial represents a feasible approach for a supplementation study. Particular attention to children of lower socioeconomic status may enhance participation and retention when conducting intervention studies among diverse populations.

The role of curriculum dose for the promotion of fruit and vegetable intake among adolescents: results from the Boost intervention.

BACKGROUND: Multi-component interventions combining educational and environmental strategies have proved effective in increasing children and adolescents' fruit and vegetable intake. However such interventions are complex and difficult to implement and several studies report poor implementation. There is a need for knowledge on the role of dose for behaviour change and for assessment of intervention dose to avoid conclusions that intervention components which are not implemented are ineffective. This study aimed to examine 1) the association between dose of a class curriculum and adolescents' fruit and vegetable intake in a school-based multi-component intervention, 2) if gender and socioeconomic position modify this association. METHODS: We carried out secondary analysis of data from intervention schools in the cluster-randomized Boost study targeting 13-year-olds' fruit and vegetable intake. Teacher- and student data on curriculum dose delivered and received were aggregated to the school-level and class-level (only possible for student data). We analysed the association between curriculum dose and students' (n 995) self-reported fruit and vegetable intake (24-h recall questionnaire) after finalization of the intervention using multi-level analyses. Potential moderation was examined by analyses stratified by gender and socioeconomic position. RESULTS: Average dose received at class-level was significantly associated with students' fruit and vegetable intake (10 g (CI: 0.06, 20.33) per curricular activity received). In stratified analyses the association remained significant among boys only (14 g (CI: 2.84, 26.76) per curricular activity received). The average dose delivered and received at the school-level was not significantly associated with students' intake. CONCLUSIONS: We found a dose-response relationship between number of curricular activities received and adolescents' fruit and vegetable intake. The results indicate that curriculum dose received only mattered for promotion of fruit and vegetable intake among boys. Future studies should explore this gender difference in larger samples to guide the planning of school-based curricular interventions with regards to the optimal number of curricular activities required to promote behavioural change in subgroups with low fruit and vegetable intake at baseline.

Adolescents' use of the built environment for physical activity.

BACKGROUND: Physical activity is a health-enhancing behavior, but few adolescents achieve the recommended levels of moderate-to-vigorous physical activity. Understanding how adolescents use different built environment spaces for physical activity and activity varies by location could help in designing effective interventions to promote moderate-to-vigorous physical activity. The objective of this study was to describe the locations where adolescents engage in physical activity and compare traditional intensity-based measures with continuous activity when describing built environment use patterns among adolescents. METHODS: Eighty adolescents aged 11-14 years recruited from community health and recreation centers. Adolescents wore accelerometers (Actigraph GT3X) and global positioning system receivers (QStarz BT-Q1000XT) for two separate weeks to record their physical activity levels and locations. Accelerometer data provided a continuous measure of physical activity and intensity-based measures (sedentary time, moderate-to-vigorous physical activity). Physical activity was mapped by land-use classification (home, school, park, playground, streets & sidewalks, other) using geographic information systems and this location-based activity was assessed for both continuous and intensity-based physical activity derived from mixed-effects models which accounted for repeated measures and clustering effects within person, date, school, and town. RESULTS: Mean daily moderate-to-vigorous physical activity was 22 minutes, mean sedentary time was 134 minutes. Moderate-to-vigorous physical activity occurred in bouts lasting up to 15 minutes. Compared to being at home, being at school, on the streets and sidewalks, in parks, and playgrounds were all associated with greater odds of being in moderate-to-vigorous physical activity and achieving higher overall activity levels. Playground use was associated with the highest physical activity level (ß = 172 activity counts per minute, SE = 4, p < 0.0001) and greatest odds of being in moderate-to-vigorous physical activity (odds ratio 8.3, 95% confidence interval 4.8-14.2). CONCLUSION: Adolescents were more likely to engage in physical activity, and achieved their highest physical activity levels, when using built environments located outdoors. Novel objective methods for determining physical activity can provide insight into adolescents' spatial physical activity patterns, which could help guide physical activity interventions. Promoting zoning and health policies that encourage the design and regular use of outdoor spaces may offer another promising opportunity for increasing adolescent physical activity.

From violence exposure to development of sexual risk in low-income urban girls: the role of psychopathology.

This longitudinal study examined psychopathology as an explanatory mechanism linking childhood violence exposure (CVE) to sexual risk in 177 African American girls recruited from mental health clinics serving low-income communities in Chicago. Beginning at average age 14, girls completed five interviews over 2 years and a sixth assessment including trauma history. CVE reflected sexual, physical, or witnessed violence before age 12. Latent growth modeling accounted for developmental change across the six time points. Externalizing, but not internalizing, symptoms mediated the pathway from CVE to number of partners (indirect effect = .16, 95 % CIBCBS = .04-.29) and inconsistent condom use (indirect effect = .11, CIBCBS = .004-.21). Externalizing problems associated with CVE may help to explain its relationship with sexual risk in low-income, treatment-seeking African American girls. Behavioral interventions addressing aggression, impulsivity, and general risk-taking may be most effective in reducing sexual risk in this population.

Socioeconomic status gradients in inflammation in adolescence.

OBJECTIVE: To determine whether lower socioeconomic status (SES), broadly defined, is associated with increased inflammation in adolescence and whether adiposity mediates these relationships. METHODS: Fasting blood samples from 941 non-Hispanic black and white adolescents enrolled in a suburban, Midwestern school district were assayed for proinflammatory biomarkers (interleukin-6 [IL-6], tumor necrosis factor α soluble receptor 2 fibrinogen). A parent reported objective SES (parent education [E1 ≤ high school, E2 = some college, E3 = college graduate, E4 = professional degree], household income), and youth perceived SES (PSES). Multivariable linear regressions assessed the relationship of SES measures to biomarkers adjusting for age, race, sex, and puberty status. In the final step, body mass index (BMI) z score (BMIz) was added to models, and Sobel tests were performed to assess mediation by adiposity. RESULTS: Parent education was inversely associated with IL-6 (ßE1 = .11, ßE2 = .10, ßE3 = .02; p < .001). This association was attenuated but remained significant after BMIz adjustment (p = .01). Sobel testing confirmed BMIz's partial mediating role (p < .001). Parent education was also inversely associated with sTNFR2 (ßE1 = .03, ßE2 = .02, ßE3 = .001; p = .01); this relationship was mediated by BMIz. Although no main effect was noted for PSES, PSES by race interactions was observed for sTNFR2 (p = .02) and IL-6 (p = .06). High PSES was associated with lower sTNFR2 and IL-6 for white but not black youth. There were no associations with household income. CONCLUSIONS: Social disadvantage, specifically low parent education, is associated with increased inflammation in adolescence. Adiposity explains some but not all associations, suggesting that other mechanisms link lower SES to inflammation. High PSES is associated with lower inflammation for white but not black youth.

Exploring the perspectives of obese adolescent girls.

To understand obese adolescent girls' perspectives regarding their weight and health we studied video intervention/prevention assessment audiovisual narratives created by 14 obese girls ages 12 to 20 years. The narratives included interviews, monologues, and daily activities. Themes included illness conceptualizations, health concerns, health misinformation, and distress regarding appearance deriving from both within and without. The predominant theme was ambivalence about obesity. Close examination of these themes revealed potential footholds for intervention. Sensitive exploration of issues such as appearance and psychosocial distress might strengthen the patient-clinician partnership in identifying a patient's strengths and motivating weight loss.

Early Initiation of HPV Vaccination and Series Completion in Early and Mid-Adolescence.

OBJECTIVES: Routine human papillomavirus (HPV) vaccination has been recommended in the United States since 2006 but rates remain suboptimal. State-based studies suggest that initiation in late childhood at ages 9 to 10 years compared with the recommended early adolescent ages of 11 to 12 years improves series completion. No study with national scope has explored the early initiation-HPV series completion relationship. This study addresses this knowledge gap and explores whether early initiation might improve series completion by increasing time to target completion age (time pathway) or by moving initiation to an earlier developmental stage (development pathway). METHODS: Using data from the National Immunization Survey-Teen 2017-2020, a retrospective cohort of 19 575 15 to 17 year olds who initiated HPV vaccination between ages 9 and 12 years was assembled. Time pathway endpoints were series completion by ages 13 and 15 years. The development pathway endpoint was completion within 3 years of initiation. RESULTS: Early initiators were more likely to complete by ages 13 (74.0% vs 31.1%, P < .001) and 15 (91.7% vs 82.7%, P < .001) years but less likely to complete within 3 years (82.3% vs 84.9%, P = .007). The association of early initiation to completion was maintained in multivariable analyses for time pathway endpoints (age 13 years adjusted odds ratios [AOR] = 6.16; 95% confidence interval [CI], 5.45-6.96, age 15 years = AOR 2.56; 95% CI, 2.14-3.14) but not the development pathway endpoint (AOR = 0.93; 95% CI, 0.80-1.07). CONCLUSIONS: Moving routine HPV vaccination to ages 9 to 10 may improve vaccination coverage rates in early and mid-adolescence. Providers should be vigilant to patient interactions after HPV series initiation to optimize public health benefits of vaccination.

PALEOEPIDEMIOLOGY OF DIPHYLLOBOTHRIOSIS: CULTURAL AND ENVIRONMENTAL FACTORS AFFECTING ADENOCEPHALUS INTENSITY AND PREVALENCE.

Peruvian and Chilean mummies and coprolites provide a source of population-based parasitological information. This is especially true of the fish tapeworm, Adenocephalus pacificus. Our analysis of Chinchorro and Chiribaya mummies and diversified coprolite samples from Chile and Peru show variation in infection. There is a statistically significant difference in prevalence between Chinchorro hunter-gatherer and Chiribaya mixed-subsistence contexts. Furthermore, the most pronounced differences occur between populations within these groups. Chinchorro differences in cemeteries at the same location can be related to El Niño-Southern Oscillation variations. Pronounced prevalence variations between 3 Chiribaya villages within 7 km of each other relate to fish distribution and preparation variation. As with other recent archaeoparasitology studies, eggs-per-gram data exhibit overdispersion.

A prospective study of psychological distress and weight status in adolescents/young adults.

BACKGROUND: The obesity-psychological distress relationship remains controversial. PURPOSE: This study aims to assess whether adolescents' psychological distress was associated with body mass index (BMI) class membership determined by latent class analysis. METHODS: Distress (anxiety, depression) and BMI were measured annually for 4 years in 1,528 adolescents. Growth mixture modeling derived latent BMI trajectory classes for models with 2-11 classes. The relationship of distress to class membership was examined in the best-fitting model using vector generalized linear regression. RESULTS: BMI trajectories were basically flat. The five-class model [normal weight (48.8%), overweight (36.7%), obese who become overweight (3.7%), obese (9.4%), and severely obese (1.3%)] was the preferred model (Bayesian information criterion = 22789.2, df = 31; ρ = 0.84). Greater distress was associated with higher baseline BMI and, therefore, class membership. CONCLUSIONS: Psychological distress is associated with higher BMI class during adolescence. To determine whether distress "leads" to greater weight gain may require studies of younger populations.
