Self-reported hepatitis A vaccination as a predictor of hepatitis A virus antibody protection in U.S. adults: National Health and Nutrition Examination Survey 2007–2012

ObjectivesTo estimate the predictive value of self-reported hepatitis A vaccine (HepA) receipt for the presence of hepatitis A virus (HAV) antibody (anti-HAV) from either past infection or vaccination, as an indicator of HAV protection.MethodsUsing 2007–2012 National Health and Nutrition Examination Survey data, we assigned participants to 4 groups based on self-reported HepA receipt and anti-HAV results. We compared characteristics across groups and calculated three measures of agreement between self-report and serologic status (anti-HAV): percentage concordance, and positive (PPV) and negative (NPV) predictive values. Using logistic regression we investigated factors associated with agreement between self-reported vaccination status and serological results.ResultsDemographic and other characteristics varied significantly across the 4 groups. Overall agreement between self-reported HepA receipt and serological results was 63.6% (95% confidence interval [CI] 61.9–65.2); PPV and NPV of self-reported vaccination status for serological result were 47.0% (95% CI 44.2–49.8) and 69.4% (95% CI 67.0–71.8), respectively. Mexican American and foreign-born adults had the highest PPVs (71.5% [95% CI 65.9–76.5], and 75.8% [95% CI 71.4–79.7]) and the lowest NPVs (21.8% [95% CI 18.5–25.4], and 20.0% [95% CI 17.2–23.1]), respectively. Young (ages 20–29 years), US-born, and non-Hispanic White adults had the lowest PPVs (37.9% [95% CI 34.5–41.5], 39.1% [95% CI, 36.0–42.3], and 39.8% [36.1–43.7]), and the highest NPVs (76.9% [95% CI 72.2–81.0, 78.5% [95% CI 76.5–80.4)], and 80.6% [95% CI 78.2–82.8), respectively. Multivariate logistic analyses found age, race/ethnicity, education, place of birth and income to be significantly associated with agreement between self-reported vaccination status and serological results.ConclusionsWhen assessing hepatitis A protection, self-report of not having received HepA was most likely to identify persons at risk for hepatitis A infection (no anti-HAV) among young, US-born and non-Hispanic White adults, and self-report of HepA receipt was least likely to be reliable among adults with the same characteristics.     

The role of family conflict on risky sexual behavior in adolescents aged 15 to 21

PurposeFamily conflict is related to numerous risky behavioral outcomes during adolescence; however, few studies have examined how family conflict is associated with risky sexual behavior during adolescence.MethodsData from 1104 adolescents aged 15 to 21 who completed the 2008 National Longitudinal Survey of Youth were analyzed. Information on family conflict (family fighting and family criticizing) and sexual behavior (number of sexual partners in past year and use of contraception at last intercourse) was self-reported. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs).ResultsAfter adjustment, adolescents whose family members often fought had increased odds of not using contraception at last intercourse and having two or more sexual partners in the past year (OR, 1.40 [95% CI, 1.04–1.88] and OR, 1.62 [95% CI, 1.23–2.14], respectively). Adolescents whose family members often criticized each other also had increased odds of not using contraception at last intercourse and having two or more sexual partners in the past year (OR, 1.46 [95% CI, 1.12–1.90] and OR, 1.22 [95% CI, 0.96–1.55], respectively).ConclusionsFamily conflict was associated with risky sexual behaviors in this racially/ethnically diverse sample of adolescents. If confirmed in other studies, adolescents who experience family conflict may be an important population to target with information regarding safer sex practices.     

Racial-ethnic disparities in self-reported health status among US adults adjusted for sociodemographics and multimorbidities,National Health and Nutrition Examination Survey 2011–2014

ABSTRACT

Objective: To investigate racial-ethnic disparities in self-reported health status adjusting for sociodemographic factors and multimorbidities.

Design: A total of 9499 adult participants aged 20 years and older from the United States (US); reported by the National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey – for years 2011–2014. The main outcome measure was self-reported health status categorized as excellent/very good, good (moderate), and fair/poor.

Results: Of the NHANES participants, 40.7% reported excellent/very good health, 37.2% moderate health and 22.1% fair/poor health. There were 42.8% who were non-Hispanic whites, 20.2% were Hispanic, 23.8% were non-Hispanic blacks, and 13.2% were non-Hispanic Asians. Compared to non-Hispanic whites, Hispanics [Odds Ratio (OR)?=?2.91, 95% Confidence Interval (CI)?=?2.28–3.71] and non-Hispanic blacks [OR?=?1.51, 95% CI?=?1.26–1.83] were more likely to report fair/poor health, whereas, non-Hispanic Asians [OR?=?1.42, 95% CI?=?1.14–1.76] were more likely to report moderate health than excellent/very good health. Compared to those with no chronic conditions, participants with two or three chronic conditions [OR?=?9.35, 95% CI?=?7.26–12.00] and with four or more chronic conditions [OR?=?38.10, 95% CI?=?26.50–54.90] were more likely to report fair/poor health than excellent/very good health status.

Conclusion: The racial-ethnic differences in self-reported health persisted even after adjusting for sociodemographics and number of multimorbidities. The findings highlight the potential importance of self-reported health status and the need to increase health awareness through health assessment and health-promotional programs among the vulnerable minority US adults.     

Racial differences in gestational weight gain and pregnancy-related hypertension

PurposeThe aim of the study was to examine racial differences in gestational weight gain (GWG) and pregnancy-related hypertension.MethodsLogistic regression models tested racial differences in adequacy of GWG and pregnancy-induced hypertension in all singleton live births from the South Carolina 2004–2006 birth certificates.ResultsCompared with white women, black and Hispanic women had 16%–46% lower odds of gaining weight above the recommendations. However, the odds of inadequate GWG was ∼50% higher in black and Hispanic women with a pregnancy body mass index (BMI) less than 25 kg/m². Furthermore, compared with women with adequate GWG, women with excessive GWG had higher odds of pregnancy-related hypertension (underweight: 2.35, 95% confidence interval [CI; 1.66, 3.32]; normal: 2.05, 95% CI [1.84, 2.27]; overweight: 1.93, 95% CI [1.64, 2.27]; obese: 1.46, 95% CI [1.30, 1.63]). Among women with a BMI less than 25 kg/m², black women had higher odds of pregnancy-related hypertension than white women (underweight: 1.64, 95% CI [1.14, 2.36]; normal weight: 1.28, 95% CI [1.15, 1.42]), whereas among women with a BMI less than 25 kg/m², Hispanic women had 40% lower odds.ConclusionsPrograms are needed to curb excessive GWG in all racial groups and to help some sub-groups ensure adequate GWG. Maternal obesity and GWG are two factors that should be used in combination to reduce racial differences in pregnancy-related hypertension.     

School-Based Health Center Access,Reproductive Health Care,and Contraceptive Use Among Sexually Experienced High School Students

PurposeThe current analyses compared receipt of reproductive health care, contraceptive use, and screening for sexually transmitted diseases (STD) among adolescents who are sexually experienced, with or without access to a school clinic.MethodsA total of 12 urban California high schools, selected from areas with high teen pregnancy and STD rates, half with school-based health centers (SBHCs), participated in an intervention study designed to improve sexual health among adolescents. Of the participating students, 44% indicated that they had ever had intercourse and were included in these analyses.ResultsAccess to an SBHC did not influence receipt of reproductive health care for either males or females and did not influence contraceptive use, either hormonal or condoms, for males. For females, however, those with access to an SBHC had increased odds of having received pregnancy or disease prevention care (adjusted odds ratio [AOR] = 1.45, 95% confidence interval [CI] = 1.16–1.80), having used hormonal contraceptives at last sex (AOR = 1.68, 95% CI = 1.24–2.28), and were more likely to have ever been screened for an STD (AOR = 1.85, 95% CI = 1.43–2.40). Also among female students, those with access to an SBHC were more likely to have used emergency contraception at last sex (AOR = 2.1, 95% CI = 1.08–4.22).ConclusionAlthough access to an on-site clinic does not seem to lead to increases in all types of reproductive care in the population as a whole, sexually active females are more likely to have received more specific care and to have used hormonal contraceptives if their school has an SBHC.     

Television Use and Snacking Behaviors Among Children and Adolescents in China

PurposeTelevision (TV) use has been linked with poor eating behaviors and obesity in young people. This study examines the association between TV watching and paying attention to TV commercials with buying and requesting snacks seen on commercials, and eating snacks while watching TV among youth in China.MethodsData from 1,552 participants (ages 6–17.99) in the 2004 China Health and Nutrition Survey were analyzed cross-sectionally. The 2004 China Health and Nutrition Survey was conducted in nine Chinese provinces.ResultsMost respondents (92.2%) reported watching TV; on average children (6–11.99 years old) and adolescents (12–17.99 years old) watched TV for 9–10 hours per week. Nearly half (42.9%) of all the respondents said they “sometimes” or “often” paid attention to TV commercials. Respondents who reported paying attention to commercials had higher odds of requesting snacks (odds ratio [OR] = 3.43; 95% confidence interval [CI] = 2.55–4.60) and buying snacks (OR = 2.73; 95% CI = 2.17–3.43) seen on TV, and eating snacks while watching TV (OR = 1.60; 95% CI = 1.23–2.07) than those who did not pay attention. However, frequency of watching TV was not significantly related to snacking.ConclusionAttention to TV commercials for snack foods may be one of the factors affecting the increase in obesity among children and adolescents in China.     

Prevalence of intellectual disability among eight-year-old children from selected communities in the United States, 2014

BackgroundChildren with intellectual disability (ID), characterized by impairments in intellectual functioning and adaptive behavior, benefit from early identification and access to services. Previous U.S. estimates used administrative data or parent report with limited information for demographic subgroups.ObjectiveUsing empiric measures we examined ID characteristics among 8-year-old children and estimated prevalence by sex, race/ethnicity, geographic area and socioeconomic status (SES) area indicators.MethodsWe analyzed data for 8-year-old children in 9 geographic areas participating in the 2014 Autism and Developmental Disabilities Monitoring Network. Children with ID were identified through record review of IQ test data. Census and American Community Survey data were used to estimate the denominator.ResultsOverall, 11.8 per 1,000 (1.2%) had ID (IQ ≤ 70), of whom 39% (n = 998) also had autism spectrum disorder. Among children with ID, 1,823 had adaptive behavior test scores for which 64% were characterized as impaired. ID prevalence per 1,000 was 15.8 (95% confidence interval [95% CI], 15.0–16.5) among males and 7.7 (95% CI, 7.2–8.2) among females. ID prevalence was 17.7 (95% CI, 16.6–18.9) among children who were non-Hispanic black; 12.0 (95% CI, 11.1–13.0), among Hispanic; 8.6 (95% CI, 7.1–10.4), among non-Hispanic Asian; and 8.0 (95% CI, 7.5–8.6), among non-Hispanic white. Prevalence varied across geographic areas and was inversely associated with SES.ConclusionsID prevalence varied substantively among racial, ethnic, geographic, and SES groups. Results can inform strategies to enhance identification and improve access to services particularly for children who are minorities or living in areas with lower SES.     

COVID-19 vaccine hesitancy among people living with HIV in a low-resource setting: A multi-center study of prevalence,correlates and reasons

BackgroundHesitancy to COVID-19 vaccine may worsen the burden of COVID-19 among people living with HIV (PLHIV), who are at a higher risk of COVID-19-related hospitalization and death, compared to HIV non-infected individuals. Therefore, we evaluate the predictors and reasons for COVID-19 vaccine hesitancy among unvaccinated PLHIV in six antiretroviral therapy (ART) clinics across northern Nigeria.MethodologyIn this cross-sectional study, conducted between October 2021 and February 2022 in six hospitals across two geopolitical regions of Nigeria, we utilized interviewer-administered questionnaires to assess COVID-19 vaccine hesitancy among a convenience sample of 790 eligible adult PLHIV. Hesitancy was defined as answering ‘no' or ‘maybe’ to a question asking participants their willingness to accept the COVID-19 vaccine. A multivariate logistic regression model was used to estimate the adjusted odds ratio (aOR) and 95% confidence interval (CI) of the factors associated with COVID-19 vaccine hesitancy among PLHIV.ResultsOf the total 660 unvaccinated participants included in the analysis (61.82% female, mean age [SD] of 39.76 [10.75]), 381 (57.72%) were hesitant to COVID-19 vaccine. Being 50 years and older (aOR: 0.43; 95% CI: 0.21–0.89), being unemployed (aOR: 0.57; 95% CI: 0.34–0.95), experiencing the adverse effects of ART (aOR: 0.36; 95% CI: 0.15–0.86), and perception of being at high risk of contracting COVID-19 (aOR: 0.22; 95% CI: 0.13–0.37) were associated with significantly lower odds of hesitancy. Conversely, being female (aOR: 1.64; 95% CI: 1.02–2.61) and attending ART clinics at state administrative capital cities (IIDH Kano [aOR: 2.40; 95% CI: 1.10–5.25], MMSH Kano [aOR: 5.59; 95% CI: 1.97–10.66], YSSH Damaturu [aOR: 9.88; 95% CI: 4.02–24.29] vs. GH Gashua) were associated with significantly higher odds of hesitancy. The most common reasons for hesitancy include fear of potential adverse effects, skepticism about vaccine efficacy, the rapid development of the COVID-19 vaccine, and the perceived lack of effort to develop a cure or vaccine for HIV/AIDS.ConclusionInterventions aimed at combating misperceptions and misinformation regarding the COVID-19 vaccination program may reduce the prevalence of COVID-19 vaccine hesitancy among unvaccinated PLHIV.     

Painfully Obvious: A Longitudinal Examination of Medical Use and Misuse of Opioid Medication Among Adolescent Sports Participants

PurposeThe objective of this longitudinal study was to assess the prevalence of medical use, medical misuse, and non-medical use of opioid medication among adolescents who participate in organized sports.MethodsData for this study were taken from the Secondary Student Life Survey. A total of 1,540 adolescents participated in three waves of data collection occurring between the 2009–2010 and 2011–2012 school years, with 82% of the baseline sample completing all three waves.ResultsUsing generalized estimating equation models to analyze the longitudinal data, it was found that male adolescents who participated in organized sports during each wave of the Secondary Student Life Survey had higher odds of being prescribed an opioid medication (i.e., medical use) during the past year (adjusted odds ratio [AOR], 1.86; 95% confidence interval [CI], 1.23–2.82), higher odds of past-year medical misuse of opioid medication as a result of taking too much (AOR, 10.5; 95% CI, 2.42–45.5), and higher odds of past-year medical misuse of opioid medication to get high (AOR, 4.01; 95% CI, 1.13–14.2) compared with males who did not participate in organized sports during the study period. Among females, no association was found between participation in organized sports and medical use, medical misuse, and non-medical use of opioid medication.ConclusionsThe results of this study indicate that adolescent males who participate in sports may have greater access to opioid medication, which puts them at greater risk to misuse these controlled substances.     

Multimorbidity is associated with uptake of influenza vaccination

ObjectivePatients with chronic conditions have higher rates of severe influenza-related illness and mortality. However, influenza vaccination coverage in high-risk populations continues to be suboptimal. We describe the association between cumulative disease morbidity, measured by a previously validated multimorbidity index, and influenza vaccination among community-dwelling adults.MethodsWe obtained interview and medical record data for participants ≥18 years who sought outpatient care for influenza-like illness between 2011 and 2016 as part of an outpatient-based study of influenza vaccine effectiveness. We defined cumulative disease morbidity by using medical diagnosis codes to calculate a multimorbidity-weighted index (MWI) for each participant. MWI and influenza vaccination status was evaluated by logistic regression. Akaike information criterion was calculated for all models.ResultsOverall, 1458 (48%) of participants out of a total of 3033 received influenza vaccination. The median MWI was 0.9 (IQR 0.00–3.5) and was higher among vaccinated participants (median 1.6 versus 0.0; p < 0.001). We found a positive linear association between MWI and vaccination, and vaccination percentages were compared between categories of MWI. Compared to patients with no multimorbidity (MWI = 0), odds of vaccination were 17% higher in the second category (MWI 0.01–1.50; [OR: 1.17, 95% CI: 0.92–1.50]), 58% higher in the third category (MWI 1.51–3.00; [OR: 1.58, 95% CI: 1.26–1.99]), 130% higher in the fourth category (MWI 3.01–6.00; [OR: 2.30, 95% CI: 1.78–2.98]) and 214% higher in the fifth category (MWI 6.01–45.00;[OR: 3.14, 95% CI: 2.41–4.10]). Participants defined as high-risk had 86% greater odds of being vaccinated than non-high-risk individuals (OR: 1.86, 95% CI: 1.56–2.21). The AIC was lowest for MWI compared with high-risk conditions.ConclusionsOur results suggest a dose response relationship between level of multimorbidity and likelihood of influenza vaccination. Compared with high-risk condition designations, MWI provided improved precision and a better model fit for the measurement of chronic disease and influenza vaccination.     

Hierarchical Modeling of Psychosocial,Parental, and Environmental Factors for Susceptibility to Tobacco Product Use in 9–10-Year-Old Children

PurposeTobacco use during early adolescence can harm brain development and cause adverse health outcomes. Identifying susceptibility in early adolescence before initiation presents an opportunity for tobacco use prevention.MethodsData were drawn from the Adolescent Brain and Cognitive Development study that enrolled 9–10-year-old children in 21 US cities between 2016 and 2018 at baseline. Separate nested hierarchical models were performed to incrementally examine the associations of sociodemographic factors, psychosocial influences, parental substance use, immediate social contacts, and perceived neighborhood safety with tobacco use susceptibility among never tobacco users (n = 10,449), overall and stratified by gender.ResultsA total of 16.6% of youths who have never used tobacco reported susceptibility to tobacco. Females (vs. males, adjusted odds ratio [AOR] [95% confidence interval {CI}] = 0.80 [0.70–0.91]), positive parental monitoring (AOR [95% CI] = 0.76 [0.66–0.87]) and positive school environment (AOR [95% CI] = 0.95 [0.93–0.98]) were associated with reduced susceptibility to tobacco use. Parental education level (high school, AOR [95% CI] = 1.52 [1.02–2.28]; bachelor's degree, AOR [95% CI] = 1.53 [1.03–2.28]; or postgraduate degree, AOR [95% CI] = 1.54 [1.03–2.3] vs. less than high school), youth substance ever use (AOR [95% CI] = 2.24 [1.95–2.58]), internalizing problems (AOR [95% CI] = 1.03 [1–1.06]), and high scores on negative urgency, lack of premeditation, lack of perseverance, sensation seeking, and positive urgency-impulsive behavior scale were associated with increased susceptibility to tobacco use. Stratified analysis showed that parent-perceived neighborhood safety was associated with reduced susceptibility to tobacco use among males but not among females (AOR [95% CI] = 0.89 [0.81–0.99]) vs. (AOR [95% CI] = 1.01 [0.9–1.13]). A positive school environment was associated with lower susceptibility to tobacco use among females but not among males.DiscussionParental, environmental, and psychosocial factors influence early childhood tobacco susceptibility. Family and school-based tobacco prevention programs should consider integrating these factors into primary school curricula to reduce youth tobacco susceptibility and later initiation.     

Association between Sexual Behaviors,Bullying Victimization and Suicidal Ideation in a National Sample of High School Students: Implications of a Sexual Double Standard

PurposeThe sexual double standard is the notion that women are more harshly judged for their sexual behaviors than men. The purpose of this study was to investigate if the sexual double standard could explain gender differences in bullying victimization among adolescents and the extent to which that relationship correlated with depression and suicidal ideation.MethodsAnalyses were conducted using a sample of high school students (n = 13,065) from the 2011 Youth Risk Behavior Survey, a cross-sectional and national school-based survey conducted by the Centers for Disease Control and Prevention. Data were assessed using multiple logistic regression, gender-stratified analyses, and interaction terms.FindingsStudents who engaged in sexual intercourse (sexually active) had higher odds of being bullied. When this association was stratified by gender, odds of being bullying increased for girls (odds ratio [OR], 1.83; 95% CI, 1.58–2.13) and decreased for boys (OR, 0.94; 95% CI, 0.77–1.16). Sexually active students who were bullied also displayed more than five times (OR, 5.65; 95% CI, 4.71–6.78) the adjusted odds of depression and three times (adjusted OR, 3.38; 95% CI, 2.65–4.32) the adjusted odds of suicidal ideation compared with students who reported neither of those behavioral characteristics. When stratified by gender, girls had slightly higher odds of depression and suicidal ideation but overall, the odds remained strong for both genders.ConclusionsResults provide some evidence that a sexual double standard exists and may play a prominent role in bullying victimization among girls. Therefore, addressing the sexual double may be important to consider when tailoring school bullying intervention programs.     

Facteurs associés à la vaccination HPV chez les jeunes filles de 13 à 14 ans dans le canton de Genève,Suisse

BackgroundSchool vaccination programs against human papilloma virus (HPV) have been implemented in most Western countries. Only a few studies have investigated socio-economic factors related to school-based vaccination.MethodA cross-sectional study was conducted using the vaccination cards of 1158 randomized girls aged 13 to 14 years enrolled in the public schools of the canton of Geneva. Several other socio-economic variables (nationality, socio-professional category and marital status of the parents) were collected.ResultsImmunization coverage for three doses of HPV vaccine was 56%. After having controlled the covariates, Portuguese adolescents (adjusted OR [95% CI]: 4.18 [1.76–9.92]), adolescents whose mothers were workers (adjusted OR [95% CI]: 1.91 [1.38–2.65]) or married (adjusted OR [95% CI]: 1.44 [1.06–1.98]) showed significantly higher immunization rates than Swiss adolescents or those whose mothers’ socio-professional category was senior manager or executive.ConclusionThis study shows that the HPV vaccine coverage is not yet optimal in Geneva and varies significantly according to the socio-economic status, thus better promotion of HPV vaccination for certain target groups must be implemented.     

Description of tobacco use and cessation among Bhutanese refugees participating in a tobacco cessation program

Objectives. To compare the tobacco use, exposure, and cessation differences between Bhutanese refugee and non-Hispanic Caucasian tobacco users in a US federally qualified health center tobacco cessation program.

Design. A retrospective cohort study reviewing data from 374 patients counseled on tobacco cessation was performed. Demographic information, tobacco use history, exposure to tobacco, and type of tobacco used characterized baseline assessments. The patient record was followed forward in time to evaluate tobacco cessation outcomes as the dependent variable. Data were analyzed using odds ratios and the Mann–Whitney U-test.

Results. Data analysis included 318 patients (211 non-Hispanic Caucasian patients and 107 Bhutanese refugee patients). Bhutanese refugees demonstrated a higher likelihood of smokeless tobacco product use than the non-Hispanic Caucasian population (67.3% vs 1%, OR?=?214.971, 95% CI 50.429, 916.383), and a greater odds of having household tobacco users (OR?=?2.533, 95% CI 1.532, 4.186). Likewise, the non-Hispanic Caucasian population exhibited larger odds of smoking cigarettes vs the Bhutanese population (97.2% vs 26.2%, OR?=?96.399, 95% CI 38.449, 241.687), had a higher odds of passive smoke exposure (OR?=?12.765, 95% CI 5.36, 30.393), and higher likelihood of a past quit attempt (OR?=?9.037, 95% CI 5.180, 15.765). Significant gender differences with regard to type of tobacco used were noted among Bhutanese refugees. Bhutanese refugees demonstrated significantly higher likelihood of tobacco cessation, compared with the non-Hispanic Caucasian population, at all length cutpoints, while showing no difference in number of follow-up visits or median time followed.

Conclusion. These culture-specific findings, showing unique tobacco use characteristics and increased cessation among the Bhutanese refugee population, provide novel information helpful to professionals identifying and treating these individuals for tobacco cessation. More research is needed to confirm our results and findings.     

Factors Related to Undiagnosed Asthma in Urban Adolescents: A Multilevel Approach

PurposeWe report the results of a school-based asthma case-identification survey to determine the prevalence and predictors of possible undiagnosed asthma in a population of urban adolescents.MethodsDuring school years 2006–2008, middle school students in Oakland, California, completed a brief survey adapted from the International Study of Asthma and Allergy in Children. Students were classified into one of three categories: no asthma, current asthma, or possible undiagnosed asthma. Students reported demographic information and residential address, which was geocoded and matched tract-level data from the US Census 2000, Oakland land use designations, public and assisted housing locations, and distance from closed-access roadways. Logistic regression was used to examine factors associated with possible undiagnosed asthma.ResultsOf the 4,017 students who completed the survey, 4.8% (95% confidence interval [CI]: 4.1, 5.5) were classified as possible undiagnosed asthma. Female students (odds ratio: 1.53, 95% CI: 1.07, 2.19) and students who resided in an urban residential area (odds ratio: 2.05, 95% CI: 1.05, 4.05) had significantly increased odds of classification as “possible undiagnosed asthma” compared to current asthma. Percentage of noncitizen recent immigrants in a census tract was related to increased odds of possible undiagnosed asthma. Residence in a census tract with older residential units was significantly associated with decreased odds of undiagnosed asthma.ConclusionsIn urban settings, school-based asthma surveillance can aid in the identification of children with possible undiagnosed asthma. Implementation of a geographic information systems framework can enhance the identification of demographic and physical environmental factors associated with possible undiagnosed asthma.     

Underage E-Cigarette Purchasing and Vaping Progression Among Young Adults

PurposeDespite laws prohibiting sale of e-cigarettes to individuals aged less than 21 years, many underage young adults purchase e-cigarettes from retail stores, which may increase likelihood of continued use due to a greater access to vaping products and exposure to point-of-sale marketing.MethodsData are from a prospective cohort of young adults aged 18–20 years in Los Angeles who had ever used e-cigarettes at baseline (N = 1,029). We evaluated the association of underage e-cigarette purchasing behavior (owned and purchased vs. owned but never purchased vs. never owned an e-cigarette) with subsequent vaping frequency, intensity, and dependence symptoms one year later, adjusting for vaping behaviors prior to baseline; additional models evaluated whether associations differed by purchase location or product type.ResultsAt baseline, 332 (32%) had purchased e-cigarettes while underage, 227 (22%) owned but never purchased e-cigarettes themselves, and 470 (46%) never owned an e-cigarette. Compared to never owning e-cigarettes, those who had purchased their own e-cigarettes vaped more days in the past month (rate ratio [RR] = 2.97; 95% confidence interval [CI]: 2.15–4.09), had more vaping episodes per day (RR: 2.58; 95% CI: 2.12–3.14), vaped more puffs per vaping episode (RR: 1.90; 95% CI: 1.61–2.23), and had greater odds of dependence (odds ratio: 3.68; 95% CI: 2.51–5.40); elevated estimates were also observed for those who owned but never purchased e-cigarettes (vs. never owned). Vaping dependence was greatest among participants who purchased JUULs or other pod-mods.DiscussionParticipants who purchased e-cigarettes underage subsequently vaped more intensely and had greater vaping dependence. Regulations that reduce underage retail access to e-cigarettes may help prevent vaping progression among those most at risk of dependence.     

Are Illinois Contraceptive Providers Comfortable Providing Care to Adolescents? Results From a Statewide Provider Needs Assessment

ObjectivesLegislation allows adolescents to access comprehensive contraceptive care; however, provider practices remain unclear. We examined predictors of provider knowledge and comfort surrounding the provision of contraceptive care to adolescents.MethodsWe mailed a survey to Illinois contraceptive providers (n = 251). Study outcomes include 1) knowledge of adolescent consent laws, 2) comfort asking for time alone with adolescents, 3) comfort providing contraception to adolescents without parental consent, and 4) comfort providing long-acting reversible contraception (LARC) to adolescents without parental consent. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs).ResultsMost providers are knowledgeable of consent laws (90%) and report being comfortable asking for time alone with adolescents (94%) and comfortable providing contraception to adolescents without parental consent (88%). Having a large proportion of patients who are eligible for family planning services was associated with increased comfort asking for time alone with adolescents (aOR, 7.03; 95% CI, 1.58–31.3) and providing contraception to adolescents (aOR, 4.0; 95% CI, 1.4–11.1). Only one-half (54%) were comfortable providing LARC methods to adolescents, with higher comfort among providers who: received more than 2 days of formal family planning training (aOR, 2.77; 95% CI, 1.2–6.2), specialized in obstetrics-gynecology (aOR, 5.64; 95% CI, 2.1–15.1), and had a patient population with more than 50% patients from minoritized racial/ethnic groups (aOR, 2.9; 95% CI, 1.2–6.6).ConclusionsAlthough knowledge of consent laws was high, gaps remain. Only one-half of our sample indicated comfort with the provision of LARC methods without parental consent. Additional efforts to increase provider comfort with all contraceptive methods and training on adolescent-centered practices may be required to meet the needs of adolescent patients.
