Patterns and factors associated with electrolyte abnormalities among patients with heart failure in Uganda.

Electrolyte abnormalities (EAs) worsen the clinical course of patients with heart failure (HF). The patterns of EAs vary among patients with HF. This study investigated patterns and factors associated with EAs among patients with HF admitted to Hoima Regional Referral Hospital (HRRH) in western Uganda. This hospital-based cross-sectional study used quantitative data of 384 HF patients admitted at HRRH between 21st February and 15th May 2023. Data on sociodemographic, lifestyle, and medical characteristics were collected and presented as descriptive statistics. EAs were considered electrolyte values below or above the reference normal ranges. Bivariate and multiple logistic regression analyses were conducted to establish associations. An association with a p < 0.05 is considered statistically significant. Of 384 HF patients, 342 (89.1%) had EAs. Hypocalcemia was the most common EA, 165 (43.0%). Among the patients, 69 (18.0%) were on diuretics, 185 (48.2%) were on angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs), and 105 (27.3%) were on calcium channel blockers (CCBs). Additionally, 264 (68.8%) had a history of hypertension, and 20 (5.2%) demonstrated good drug adherence. Patients with good drug adherence had lower odds of EAs (Adjusted Prevalence Odds Ratio [Adjusted POR] = 0.2, 95% CI: 0.1-0.7, p = 0.009). Those on diuretics had higher odds of EAs compared to those on ACEIs/ARBs and CCBs, with an Adjusted POR of 5.7 (95% CI: 1.3-15.0, p = 0.019). A history of hypertension also increased the odds of EAs (Adjusted POR = 4.0, 95% CI: 1.9-8.4, p < 0.001). The prevalence of EAs in patients with HF at HRRH was high, with hypocalcemia being the most common. Patients with good drug adherence had lower odds of EAs. On the other hand, diuretic use and a history of hypertension were associated with increased odds of EAs.

Discrimination and Racial Inequities in Self-reported Mental Health Among Immigrants and Canadian-Born Individuals in a Large, Nationally Representative Canadian Survey.

We examined the link between discrimination and self-rated mental health (SRMH) among immigrants and Canadian-born individuals, stratified according to an individual's identification as racialized or white. Using data from Canada's General Social Survey (2014) (weighted N = 27,575,000) with a novel oversample of immigrants, we estimated the association of perceived discrimination with SRMH separately among immigrants and Canadian-born individuals and stratified by racialized status. Among immigrants, we also investigated whether age-at-arrival attenuated or strengthened associations. The prevalence of discrimination was higher among racialized compared to white immigrants (18.9% versus 11.8%), and among racialized compared to white non-immigrants (20.0% versus 10.5%). In the adjusted model with immigrants, where white immigrants not reporting discrimination were the referent group, both white (adjusted prevalence odds ratio [aPOR] 6.11, 95% confidence interval [CI] 3.08, 12.12) and racialized immigrants (aPOR 2.28, 95% CI 1.29, 4.04) who experienced discrimination reported poorer SRMH. The associations were weaker among immigrants who immigrated in adulthood. In the adjusted model with non-immigrants, compared to unexposed white respondents, Canadian-born white respondents who experienced discrimination reported poorer SRMH (aPOR 3.62, 95% CI 2.99, 4.40) while no statistically significant association was detected among racialized respondents (aPOR 2.24, 95% CI 0.90, 5.58). Racialized respondents experienced significant levels of discrimination compared to white respondents irrespective of immigrant status. Discrimination was associated with poor SRMH among all immigrants, with some evidence of a stronger association for white immigrants and immigrants who migrated at a younger age. For Canadian-born individuals, discrimination was associated with poor SRMH among white respondents only.

The food environment and hypertension: A cross-sectional analysis in Black breast cancer survivors in Maryland

ObjectivesThe Food Environment Index (FEI) has shown varying positive impacts on health outcomes related to diabetes, obesity, and hypertension. However, a relationship between FEI and hypertension among breast cancer (BC) survivors, particularly Black women survivors, remains underexplored. Black women who are BC survivors have a high prevalence of hypertension and increased risk of mortality compared to White women with BC. Our analysis aims to fill this gap by assessing the FEI's association with hypertension in this population. DesignUtilizing social media recruitment strategies and BC survivor networks, 100 Black female BC survivors completed an online survey, that included sociodemographic and clinical characteristics as well as lifestyle factors. The 2023 FEI County Health Rankings was used to assess the food environment and the index ranges from 0 (worst) to 10 (best). Adjusted prevalence odds ratios (PORs) and 95 % confidence intervals (CI) were calculated for the associations between FEI, sociodemographic and clinical factors, and hypertension status. ResultsAmong the 94 study participants with data on hypertension status, 54.3 % reported a diagnosis of hypertension. Residing in counties with a below-median FEI (<8.8 v. above median: ≥8.8) was significantly associated with hypertension (POR = 4.10, 95 % CI: 1.19–14.13). Age at survey (≥50 years compared to <50 years: POR= 0.29, 95 % CI: 0.10–0.87) and household income ($75,000-$99,999 compared to > $99,999/year: POR = 12.02, 95 % CI: 2.08–69.43) were also significantly associated with hypertension. ConclusionOur study highlights the potential impact of the food environment on hypertension among Black BC survivors living in Maryland. Our findings call attention to the need for targeted interventions to improve food accessibility and quality in underserved communities, especially for special populations such as cancer survivors.

Cross-sectional associations of low body mass index and being underweight with joint damage in Chinese patients with rheumatoid arthritis.

To characterize BMI in Chinese patients with RA vs US patients and examine its association with joint damage in Chinese patients. Each of the 1318 patients from a real-world Chinese RA population was first stratified by gender and then individually age-matched with one American RA patient from the US National Health and Nutritional Examination Survey 1999-2018. Data on BMI, bilateral hand radiographs and risk factors at enrolment were collected but radiographs were unavailable for the American patients. Logistic regression was used to evaluate the association of BMI with radiographic joint damage (RJD) in Chinese patients. Chinese patients had a significantly lower BMI [(weighted) median 21.8 vs 29.8 kg/m2; P < 0.001] and a higher prevalence of being underweight (15.2% vs 1.1%; P < 0.05) than their American counterparts. Underweight Chinese patients (BMI <18.5) had higher modified total Sharp scores (median 17 vs 10) and joint space narrowing (JSN) subscores (median 6 vs 2) (both P < 0.05) than normal-weight patients (BMI ≥18.5-<24). After controlling for confounding, continuous BMI was cross-sectionally negatively associated with RJD [adjusted prevalence odds ratio (OR) 0.90 (95% CI 0.85, 0.96)] and JSN [adjusted prevalence OR 0.92 (95% CI 0.87, 0.96)]; being underweight vs normal weight was associated with RJD [adjusted prevalence OR 2.14 (95% CI 1.37, 3.35)] and JSN [adjusted prevalence OR 1.77 (95% CI 1.10, 2.84)]. Low BMI and being underweight were cross-sectionally associated with joint damage in Chinese RA patients, especially JSN, suggesting the clinical importance of identifying underweight patients and focusing on weight gain to prevent joint damage.

Factors associated with the use of antibiotics for children presenting with illnesses with fever and cough obtained from prescription and non-prescription sources: a cross-sectional study of data for 37 sub-Saharan African countries

IntroductionFever and cough in under-five children are common and predominately self-limiting illnesses. Inappropriate prescribing of antibiotics in sub-Saharan Africa is a significant public health concern. However, prescription sources and use among children with fever or cough have not been explored. Therefore, we explored the factors associated with the use of antibiotics obtained from prescription and non-prescription sources for children with illnesses associated with fever and cough.MethodsA secondary data analysis was conducted based on the Demographic and Health Survey (DHS) data from 37 sub-Saharan African countries. A total weighted sample of 18,866 under-five children who had a fever/cough and took antibiotics were considered for this study. Given the hierarchical nature of DHS data and the use of antibiotics prescribed from the formal healthcare setting (> 10%), a multilevel modified poisson regression model was fitted. Deviance was used for model comparison and the model with the lowest deviance value was chosen as the best-fitted model. Variables with p ≤ 0.2 in the bivariable analysis were considered for the multivariable modified poisson regression model. In the multivariable multilevel modified poisson regression model, the Adjusted Prevalence Odds Ratio (APOR) with a 95% Confidence Interval (CI) and p-value < 0.05 were reported to declare a significant association with taking antibiotics for fever/cough prescribed from formal healthcare setting.ResultsIn sub-Saharan Africa, the proportion of use of antibiotics from informal healthcare setting for fever and cough among under-five children was 67.19% (95% CI: 66.51%, 67.85%). In the multilevel modified poisson regression analysis; residing in a rural area (APOR = 1.08, 95% CI: 1.04, 1.12), a child aged 36–47 months (APOR = 0.94, 95% CI: 0.90, 0.98), a child aged 48–59 months (APOR = 0.89, 95% CI: 0.84, 0.94), maternal primary education (APOR = 0.96, 95% CI: 0.93, 0.99), maternal secondary education (APOR = 0.95, 95% CI: 0.92, 0.99), belonged the middle household wealth status (APOR = 1.07, 95% CI: 1.02, 1.11), maternal exposure to news/electronic media (APR = 1.06, 95% CI: 1.02, 1.10), being from a household with 2 under-five children (APR = 0.94, 95% CI: 0.91, 0.97), being from a household with 3 under-five children (APR = 0.89, 95% CI: 0.85, 0.93), being from a household with 4 under-five children (APR = 0.90, 95% CI: 0.83, 0.98), and children of caregivers who were not involved in decision-making for their child health issues were significantly associated with taking antibiotics prescribed from formal healthcare setting for fever/cough among under-five children.ConclusionOnly two-thirds of the antibiotics used for children under five who had fever and cough were prescribed from formal healthcare setting. Our findings underscore the significance of addressing healthcare disparities, improving access to qualified healthcare providers, promoting maternal education, and empowering mothers in healthcare decision-making to ensure appropriate antibiotic use in this vulnerable population. Further research and interventions targeted at these factors are warranted to optimize antibiotic prescribing practices and promote responsible antibiotic use in the management of fever and cough in under-five children.

Prevalence and Associated Factors of Teenage Pregnancy in Sub-Saharan Africa: Multilevel Modified Poisson Regression Analysis

In sub-Saharan African countries, teenage pregnancy received less attention and weak policy responses, and the pooled prevalence of teenage pregnancy is not yet studied. Therefore, this study aimed to determine the pooled prevalence and determinants of teenage pregnancy in sub-Saharan African countries. A total weighted sample of 96,185 teenage girls were included in the study. A multilevel modified poison regression analysis model was fitted to identify factors associated with teenage pregnancy. Finally, the Adjusted Prevalence Odds Ratio (APOR) with its 95% confidence interval was reported. Statistical significance was declared at p-value &lt;.05. The overall pooled prevalence of teenage pregnancy in sub-Saharan Africa was 21.36% (95% CI: 21.10, 21.62%). Being 18 to 19 years (APOR = 1.70, 95% CI [1.64, 1.77]), teenager’s mother is working (APOR = 1.09, 95% CI: 1.06, 1.13), married adolescents (APOR = 5.54, 95% CI [5.01, 6.12]), media exposure (APOR = 0.96, 95% CI [0.94, 0.99]), middle and high wealth index (APOR = 0.96, 95% CI [0.93, 0.98]), and (APOR = 0.79, 95% CI [0.75, 0.83]), low-middle-income countries (APOR = 0.79, 95% CI [0.63, 0.92]), upper-middle-income (APOR = 0.61, 95% CI [0.41, 0.80]) and the Central African region (APOR = 1.46, 95% CI [1.29, 1.64]) were the factors found to be associated with teenage pregnancy. Teenage pregnancy in SSA was unacceptably high. Age, adolescent marital status, teenager’s mother’s working status, media exposure, wealth index, countries’ income, and regions of SSA had a significant association with teenage pregnancy. Therefore, addressing geographical disparities and socio-economic inequalities help to reduce teenage pregnancy.

Cancer Treatment Disparities in People With HIV in the United States, 2001-2019.

People with HIV (PWH) have worse cancer outcomes, partially because of inequities in cancer treatment. We evaluated cancer treatment disparities among PWH, including an assessment of changes in disparities over time. We used data from the HIV/AIDS Cancer Match Study, a population-based HIV and cancer registry linkage to examine diffuse large B-cell lymphoma (DLBCL), Hodgkin lymphoma (HL), and cancers of the cervix, lung, anus, prostate, colon, and female breast. Outcomes included receipt of (1) any cancer treatment and (2) standard therapy among patients with local-stage cancer. We assessed associations between HIV and each outcome by estimating adjusted prevalence odds ratios (aORs) with 95% CI and trends over time. We identified predictors of nonreceipt of cancer treatment in PWH. From 2001 to 2019, compared with people with cancer without HIV (n = 2,880,955), PWH (n = 16,334) were more likely to not receive cancer treatment for cervical cancer (aOR, 2.03 [95% CI, 1.52 to 2.70]), DLBCL (aOR, 1.53 [95% CI, 1.38 to 1.70]), HL (aOR, 1.39 [95% CI, 1.19 to 1.63]), lung cancer (aOR, 1.79 [95% CI, 1.65 to 1.93]), prostate cancer (aOR, 1.32 [95% CI, 1.21 to 1.44]), colon cancer (aOR, 1.73 [95% CI, 1.43 to 2.08]), and breast cancer (aOR, 1.38 [95% CI, 1.07 to 1.77]). Similar associations were observed in PWH with local-stage cancers although no difference was observed for anal cancers. The association between HIV and nonreceipt of cancer treatment significantly decreased over time for breast, colon, and prostate cancers (all P trend <.0001), but PWH remained less likely to receive treatment in 2014-2019 for DLBCL, cervix, and lung cancers. Among PWH, Black individuals, people who inject drugs, and those 65 years and older were less likely to receive cancer treatment. Disparities in receipt of cancer treatment persist for PWH in the United States in contemporary time periods. Solutions to address inequitable receipt of cancer treatment among PWH are urgently needed.

Transgender Women Experiencing Homelessness - National HIV Behavioral Surveillance Among Transgender Women, Seven Urban Areas, United States, 2019-2020.

Transgender women experience high prevalence of homelessness, which can affect their likelihood of acquiring HIV infection and can lead to poor medical outcomes. CDC analyzed data from the National HIV Behavioral Surveillance Among Transgender Women to identify whether personal characteristics and social factors affecting transgender women were associated with duration of homelessness during the past 12 months. Longer duration and chronic homelessness might indicate greater unmet needs, which increases their likelihood for acquiring HIV infection. Ordinal logistic regression was conducted to calculate adjusted prevalence odds ratios and 95% CIs for transgender women from seven urban areas in the United States experiencing homelessness 30-365 nights, 1-29 nights, and zero nights during the past 12 months. Among 1,566 transgender women, 9% reported 1-29 nights homeless and 31% reported 30-365 nights homeless during the past 12 months. Among participants who reported physical intimate partner violence or forced sex, 50% and 47%, respectively, reported experiencing 30-365 nights homeless. Furthermore, 55% who had been evicted or denied housing because of their gender identity and 58% who had been incarcerated during the past year experienced 30-365 nights homeless. The odds of transgender women experiencing longer duration of homelessness was associated with being younger and having a disability; higher psychological distress scores were associated with longer duration of homelessness. Analysis of social determinants of health found transgender women experiencing longer homelessness to be less educated, living below the Federal poverty level, and having lower social support. Therefore, focusing on HIV prevention and interventions addressing housing instability to reduce the duration of homelessness among transgender women is important. Further, integrating housing services with behavioral health services and clinical care, specifically designed for transgender women, could reduce HIV acquisition risk and improve HIV infection outcomes.

Analysis of Factors Associated with Constipation in the Population with Obesity: Evidence from the National Health and Nutrition Examination Survey

Introduction: Obesity and constipation are both global problems, but the factors associated with constipation in individuals with obesity are currently understudied. The aim of our study was to explore the factors associated with constipation in people with obesity. Methods: From three cycles of the National Health and Nutrition Examination Survey (NHANES) 2005–2010, data from 14,048 persons aged ≥20 years were collected. Variables included demographics, lifestyle, comorbidities, and dietary data. Multiple logistic regression analysis was used to calculate adjusted prevalence odds ratio (OR) and assess the relationship between different variables and constipation in population with obesity. Results: Using stool consistency definition, multivariate analysis revealed that education ≥12th grade (OR: 0.456; 95% CI: 0.300, 0.694; p = 0.00024), hypertension (OR: 0.505; 95% CI: 0.334, 0.763; p = 0.00119), polypharmacy (OR: 1.669; 95% CI: 1.104, 2.521; p = 0.01507), high cholesterol (OR: 0.400; 95% CI: 0.213, 0.750; p = 0.00430), and high dietary fiber (OR: 0.454; 95% CI: 0.245, 0.841; p = 0.01206) were substantially linked with constipation in the population with obesity. For constipation defined using stool frequency, multivariate regression analysis show constipation in people with obesity had a significant association with the female sex (OR: 2.684; 95% CI: 1.379, 5.223; p = 0.00366 multivariate), Mexican American (OR: 0.142; 95% CI, 0.033, 0.616; p = 0.00914 multivariate), hypertension (OR: 0.569; 95% CI: 0.324, 0.998; p = 0.04916), depression (OR: 2.280; 95% CI: 1.240, 4.195; p = 0.00803), occasional/often milk consumption (OR: 0.473; 95% CI: 0.286, 0.782; p = 0.00356), medium energy (OR: 0.318; 95% CI: 0.118, 0.856; p = 0.02338), polypharmacy (OR: 1.939; 95% CI: 1.115, 3.373; p = 0.01907), and medium moisture (OR: 0.534; 95% CI: 0.285, 0.999; p = 0.04959). In nonobese people, constipation was significantly associated with the female sex and high moisture but not with hypertension and polypharmacy. Conclusion: This study suggests that the population with obesity has many factors that affect constipation such as hypertension, polypharmacy, cholesterol, dietary fiber, depression, and so on, of which hypertension and polypharmacy were significant associated with constipation, regardless of definitions of constipation. Notably, hypertension might be associated with a reduced risk of constipation in people with obesity.

Lower PrEP Retention among Young and Black Clients Accessing PrEP at a Cluster of Safety Net Clinics for Gay and Bisexual Men.

Young men of color who have sex with men are vulnerable to HIV and experience poor PrEP uptake and retention. We conducted a secondary data analysis and calculated adjusted Prevalence Odds Ratios (aPORs) for PrEP retention along with 95% CIs at 90, 180, and 360 days at an organization running safety net clinics in Texas for gay and bisexual men. We found statistically significant association with age, race, in-clinic versus telehealth appointments, and having healthcare insurance. White clients had an aPOR of 1.29 [1.00, 1.67] as compared to Black clients at 90 days. Age group of 18-24 had a lower aPOR than all other age groups except 55 or older at all three time periods. Clients who met providers in person had an aPOR of 2.6 [2.14, 3.19] at 90, 2.6 [2.2, 3.30] at 180 days and 2.84 [2.27, 3.54] at 360 days. Our findings highlight the need for population-specific targeted interventions.

Financial hardship among siblings of long-term survivors of childhood cancer: A Childhood Cancer Survivor Study report.

Siblings of children with cancer may experience adverse household economic consequences, but their financial outcomes in adulthood are unknown. A total of 880 siblings (aged 18-64years) of adult-aged childhood cancer survivors were surveyed to estimate the prevalence of financial hardship by three established domains (behavioral, material, and psychological). For individual financial hardship items matching the contemporaneous National Health Interview Survey or Behavioral Risk Factor Surveillance System, siblings were compared with the general population by calculating adjusted prevalence odds ratios (ORs) to sample-weighted responses. Multivariable logistic regression models examined associations between sibling characteristics and each hardship domain and between sibling hardship and survivors' cancer/treatment characteristics. Behavioral, material, and psychological hardship was reported by 24%, 35%, and 28%, respectively. Compared with national survey respondents, siblings were more likely to report worries about medical bills (OR, 1.14; 95% confidence interval [CI], 1.06-1.22), difficulty affording nutritious foods (OR, 1.79; 95% CI, 1.54-2.07), and forgoing needed medical care (OR, 1.38; 95% CI, 1.10-1.73), prescription medications (OR, 2.52; 95% CI, 1.99-3.20), and dental care (OR, 1.34; 95% CI, 1.15-1.57) because of cost. Sibling characteristics associated with reporting financial hardship in one or more domains included female sex, older age, chronic health conditions, lower income, not having health insurance, high out-of-pocket medical expenditures, and nonmedical/nonhome debt. No survivor cancer/treatment characteristics were associated with sibling financial hardship. Adult siblings of childhood cancer survivors were more likely to experience financial hardship compared with the general population. Childhood cancer may adversely affect entire households, with potentially lasting implications.

Abstract B128: Cancer treatment inequities in people with HIV in the United States, 2001-2019

Abstract Background: People with HIV (PWH) are at increased risk of both AIDS-defining (i.e., Kaposi sarcoma, non-Hodgkin lymphoma, cervical cancer) and non-AIDS-defining cancers. Prior work with data from 1996-2010 reported that PWH with cancer in the US were less likely to receive cancer treatment. However, an updated analysis is warranted to see if the disparity in receipt of cancer treatment persists for PWH. Methods: We used data from the HIV/AIDS Cancer Match (HACM) Study, a population-based HIV and cancer registry linkage in 13 U.S. states to examine diffuse large B-cell lymphoma (DLBCL), Hodgkin-lymphoma (HL), and cancers of the cervix, lung, anal, prostate, colon, and breast. For each cancer type, we estimated adjusted prevalence odds ratios (aOR) and 95% confidence intervals using logistic regression to assess the relationship between HIV status and cancer treatment adjusted for race, age at cancer diagnosis, sex, cancer stage, year of cancer diagnosis and region. In addition, we used logistic regression to identify predictors of cancer treatment receipt in PWH by cancer site, including race, age at cancer diagnosis, sex, HIV mode of transmission, cancer stage, calendar year period of cancer diagnosis and region. Results: We evaluated 11,657 PWH with cancer and 2,687,946 patients with cancer without HIV. A total of 9,030 PWH with cancer received any cancer treatment (77.5%) compared to 2,218,200 individuals with cancer, without HIV (82.5%) who received any cancer treatment. HIV was associated with lower odds of receiving cancer treatment compared to people with cancer and no HIV for cervical cancer (aOR=0.46 95% CI: 0.35-0.60), DLBCL (0.55, 0.50-0.62), HL (0.64,0.53-0.76), lung cancer (0.57, 0.52-0.62), prostate cancer (0.74, 0.66-0.83), and colon cancer (0.60, 0.50-0.74). Non-Hispanic (NH)-Black PWH with lung cancer were less likely to receive cancer treatment compared to NH-White PWH. People who inject drugs (PWID), PWID/men who have sex with men (MSM) and heterosexual PWH were less likely to be treated for DLBCL, lung cancer and prostate cancer compared to MSM. In contrast, PWID were more likely to receive cancer treatment for anal cancer than MSM. For PWH with DLBCL, those diagnosed in 2011-2014 were 46% more likely to receive treatment (aOR=1.46, 1.00-2.12) compared to those diagnosed in 1996-2000. Conclusion: Inequities in receipt of cancer treatment persist for PWH in the US. We saw for some cancers, PWH had lower odds of receiving cancer treatment, even after controlling for important factors. Beginning in 2018, the National Comprehensive Cancer Network (NCCN) published cancer treatment guidelines explicit for PWH. Despite improvements in HIV-related treatment, inequitable receipt of cancer treatment will continue to prolong and exacerbate disparities among people with cancer with and without HIV.

Prevalence of prolonged otitis media with effusion among 2 to 3 years old Cameroonian children in the era of 13-valent pneumococcal conjugate vaccines

ObjectivesThere is data scarcity on the overall effects of pneumococcal conjugate vaccines (PCVs) on otitis media (OM) in low- and middle-income countries. The impact of the 13-valent PCV (PCV13) program on OM was evaluated in Cameroon where infant vaccination was implemented in July 2011 using a 3-dose primary series at 6, 10 and 14 weeks of age. MethodsThrough community-based surveillance, we used a retrospective cohort study design to assess OM prevalence among PCV13-vaccinated children aged 24 to 36 months in 2015. This was compared with a 2013 age-matched cohort of PCV13-unvaccinated children. OM was diagnosed by clinical inspection for chronic suppurative OM (CSOM) and tympanometry for OM with effusion (OME). CSOM was defined as draining of the middle ear with duration of more than 2 weeks and prolonged OME was defined as a flat ‘type B’ tympanogram. PCV13-vaccinated and PCV13-unvaccinated cohorts were compared by calculating prevalence odds ratios for OM and baseline characteristics. ResultsAltogether, 111 OM cases were identified; 42/433 (9.7%) in the PCV13-unvaccinated in 2013 and 69/413 (16.7%) in the PCV13-vaccinated cohort in 2015. In the 2013 baseline survey, 3/433 (0.7%) children were identified with unilateral CSOM compared to 9/413 (2.2%) in the PCV13-vaccinated cohort in 2015. Bilateral prolonged OME was diagnosed in 7/433 (1.6%) PCV13-unvaccinated children and in 12/413 (2.9%) in PCV13-vaccinated children. Proportions of children with unilateral prolonged OME were 31/433 (7.2%) in the PCV13-unvaccinated group compared with 48/413 (11.6%) in the PCV13-vaccinated group. Multivariate logistic regression analysis showed evidence that PCV13-vaccinated children in 2015 had 40% less risk of contracting OM compared to PCV13-unvaccinated children in 2013 (adjusted prevalence odds ratios = 0.60 [95% confidence interval: 0.38 to 0.94], P = 0.025). Additionally, attributable proportion estimates show that, 58% of OM infections among the PCV13-vaccinated group would still have occurred despite PCV13 vaccination. ConclusionOur findings provide significant evidence on the effect of PCV13 in decreasing OM or OME among children in this age group. It also supports justification for government's continuation of PCV13 immunization program in the absence of GAVI's funding. Further research is needed to assess the long-term impact of the PCV13 program on in OM Cameroon.

Perceived Accuracy Around Undetectable = Untransmitable Among Sexual and Gender Minorities Using Smartphones in India.

Sexual and gender minorities (SGM) using online venues in India are usually not reached by government HIV interventions, remaining an understudied yet important population. We investigated sociodemographic characteristics, sexual behaviours along with familiarity, knowledge, and correlated factors around perceived accuracy of the Undetectable = Untransmittable (U = U) slogan. Grindr users in India completed an online, cross-sectional survey in May-June 2022. We included individuals ≥ 18 years old who reported sex with men (excluding those who were born female and or identified as cis-gender female). Associations with perceived U = U accuracy were estimated using adjusted prevalence odds ratios (aPOR) with 95% confidence intervals (95% CI). The survey was completed by 3,126 eligible participants. The median age was 28 years and most participants lived in urban areas and had graduate or postgraduate education. HIV prevalence was 3.1%. Only 14% reported familiarity with the U = U slogan and after an explanation was provided, 25% perceived it as completely accurate. This was associated with knowing their HIV status (HIV Negative aPOR 1.37 [95%CI 1.1, 1.71], HIV Positive aPOR 3.39 [95%CI 2.11, 5.46]), having heard of PrEP (aPOR1.58 [95%CI 1.29,1.92]) or have used PrEP (aPOR1.56 [95%CI 1.15, 2.12]) along with use of party drugs (aPOR1.51 [95%CI 1.0 2.10]), being in touch with NGOs (aPOR 1.61 [95%CI 1.27, 2.02], p < .001) and having attended LGBTQIA + events (aPOR1.38 [95%CI 1.1, 1.73]). SGMs in India had low familiarity and low perceived accuracy around U = U. Education about U = U and innovating new strategies to reach this hidden population could reduce stigma around HIV in India.

Association between annual exposure to air pollution and systolic blood pressure among adolescents in Montréal, Canada

In adults, chronic exposure to air pollution is associated with elevated blood pressure, but few studies have examined this relationship in youth. We investigated the association between annual ambient concentrations of air pollutants (fine particulate matter [PM2.5] and nitrogen dioxide [NO2]) and systolic blood pressure (SBP) among adolescents in Montréal, Canada. Participants were students aged 15 to 17 years who provided SBP and residential postal code data in 2004/05 through their enrolment in the Nicotine Dependence in Teens study. Annual estimates for 2004 of residential exposure to NO2 and PM2.5 were provided by the Canadian Urban Environmental Health Research Consortium and linked to participants' residential postal code. Elevated SBP was defined as SBP ≥ 90th percentile adjusted for age, sex and height. Logistic regression was used to estimate odds ratios and 95% confidence intervals (CIs) for each pollutant with respect to elevated SBP, adjusted for relevant confounders. The sample consisted of 508 adolescents (mean age: 16.9, 46% male); 4% had elevated SBP. Although estimates were not statistically significant, there were generally modest positive associations between pollutant levels and SBP. The adjusted prevalence odds ratio of elevated SBP was 1.33 (95% CI: 0.64, 3.05) for every interquartile range (IQR) increase in residential PM2.5 levels (2.1μg/m3). Similarly, the adjusted prevalence odds ratio of elevated SBP was 1.17 (95% CI: 0.47, 2.70) for every IQR increase in residential NO2 levels (10.2 ppb). Findings support a possible relationship between exposure to air pollutants and increased SBP in adolescents, warranting further investigation for this important public health concern.

Employment Status in the United States and Use of Long-Acting Reversible Contraception or Moderately Effective Contraception before and after the Affordable Care Act: National Survey of Family Growth 2006–2010 and 2015–2017

Employment status has been previously associated with contraceptive use among women of reproductive age. We assessed the association between employment status and method of contraception among US women of reproductive age, before and after the implementation of the Affordable Care Act (ACA) passed in 2010. We conducted a cross-sectional study using data from the National Survey of Family Growth (NSFG): 2006–2010 survey for our pre-ACA analysis and 2015–2017 survey for post-ACA analysis. We combined the use of moderately-effective or long-acting reversible contraceptives (LARC) as the main study outcome. Multivariable logistic regression was used to estimate adjusted prevalence odds ratios (aPOR) and 95% confidence intervals (CI). Our study included 5,572 women pre-ACA and 2,340 women post-ACA. Pre-ACA, non-Hispanic white women who were employed were significantly more likely to use moderately-effective or LARC contraceptives (aPOR = 1.66; 95% CI = 1.28, 2.14), but post-ACA, this association was non-significant (aPOR = 0.94; 95% CI = 0.67, 1.33). Findings were not significant for other race/ethnic groups in either time frame. Our study shows that being employed was no longer associated with contraceptive method during a post-ACA time period among non-Hispanic white women. Modifications to the ACA should be scrutinized to further evaluate the impact it may have on women’s access to moderately-effective or LARC contraception.

7563 Association between Race and Utilization of Hysterectomy and Non-Hysterectomy Surgeries for Endometriosis

<h3>Study Objective</h3> To evaluate the association between race and self-reported prevalence of hysterectomy and non-hysterectomy surgeries for endometriosis treatment. <h3>Design</h3> This cross-sectional study used data from the National Survey of Family Growth (NSFG). The main study outcome was self-reported receipt of hysterectomy and non-hysterectomy surgeries for endometriosis. Multivariable logistic regression estimated adjusted prevalence odds ratios (aPOR) and 95% confidence intervals (CI). Differences in social determinants of health (SDH) among women who did and did not receive non-hysterectomy endometriosis surgery were tested using Rao-Scott chi-square analysis. <h3>Setting</h3> Data from the 2017-2019 NSFG cycle was collected from participants throughout the United States via in-person interviews and self-administered questionnaires. <h3>Patients or Participants</h3> This study included persons who identify as female, ages 15-49 years, who reported receiving a diagnosis of endometriosis by a healthcare provider. <h3>Interventions</h3> The main exposure was race, stratified by Non-Hispanic White, Non-Hispanic Black, Hispanic and other. <h3>Measurements and Main Results</h3> Of 6,141 survey participants, 314 (5.11%) answered yes to ever being diagnosed with endometriosis. Among women with endometriosis, there was no statistically significant difference in age, parity, history of PID and insurance status by race. Although there were no statistically significant differences in the odds of having a hysterectomy for endometriosis when stratified by race, Black women had a significantly lower odds of having non-hysterectomy endometriosis surgery compared to White women (aPOR=0.22, 95% CI 0.06, 0.77). The analysis of SDH revealed a lower prevalence of poverty among women who received non-hysterectomy endometriosis surgery (p=0.0041). However, including this variable in the logistic regression model did not change the findings. <h3>Conclusion</h3> White women have over four times higher odds of receiving non-hysterectomy endometriosis surgery compared to Black women in our full adjusted model, which cannot be explained by a secondary analysis of SDH. Further examination of factors that may influence decisions for non-hysterectomy surgery for endometriosis is warranted to better understand disparities in care.

Associations of race/ethnicity and socioeconomic factors with vaccination among US adults during the COVID-19 pandemic, January to March 2021

To date, there has been limited data available to understand the associations between race/ethnicity and socioeconomic and related characteristics with novel coronavirus disease (COVID-19) vaccination in the United States. I leveraged the large, nationally-representative cross-sectional surveys of the U.S. Household Pulse Survey between January and March 2021 with relatively complete race/ethnicity and socioeconomic data to examine national trends in levels of COVID-19 vaccine initiation and intention in adults aged 18–85 years. I further estimated the multivariable associations between race/ethnicity, education, income, and financial hardship with the adjusted prevalence odds ratios of: 1) receipt of ≥1 COVID-19 vaccine dose; and 2) among those unvaccinated, the definite intention to receive a vaccine. I observed persistent disparities in vaccine initiation for non-Hispanic Blacks, Hispanics, and non-Hispanic multiracial/other race persons, and vaccine intention for Blacks and multiracial/other race persons, compared to non-Hispanic Whites and Asians. In late March 2021, the prevalence estimates of Hispanics and Blacks receiving a vaccine were 12-percentage points and 8-percentage points lower than for Whites, respectively. Education and income exhibited dose–response relationships with vaccine initiation (P for trend ≤0.01 and <0.001, respectively). Substantial financial hardship was linked to 35–44% lower adjusted odds of vaccination (P<.001). In this large, nationally-representative study, I found persistent racial/ethnic and socioeconomic disparities in vaccine initiation and intention, more than three months after COVID-19 vaccines first became available. Addressing these persistent racial/ethnic and socioeconomic inequities in vaccination is essential to mitigate the pandemic's higher risks of infection and adverse health outcomes in Hispanic, Black, and socioeconomically-disadvantaged communities.

Benzophenone-3 and antinuclear antibodies in U.S. adolescents and adults ages 12-39 years.

BackgroundBetween 1988 and 2012, prevalence of antinuclear antibodies (ANA) increased in the U.S., especially in adolescents and non-Hispanic Whites. Female predominance of ANA suggests a role for hormonal factors, including xenobiotic exposures that may disrupt endocrine signaling. Benzophenone-3 (BP-3) is one such chemical with increasing exposure through sunscreen use. We investigated whether urinary BP-3 levels were related to ANA in adolescents and young adults.MethodsIn a sample of 1,785 individuals ages 12-39 years in the National Health and Nutrition Examination Survey (NHANES; 2003-4, 2011-12), we examined cross-sectional associations of ANA (N=192; 3+ or 4+ at the 1:80 dilution, measured by HEp-2 immunofluorescence) with urinary BP-3, and other phenols bisphenol-A, triclosan, and parabens. Adjusted prevalence odds ratios (POR) were calculated in season-stratified models [winter (November-April) and summer (May-October)], given differences in sunscreen use and BP-3 concentrations.ResultsBP-3 concentrations (detected in >98.5% of individuals) did not differ by ANA positivity in the summer (geometric mean, GM 30.6 ng/ml ANA-positive vs. 35.3 ANA-negative; GM ratio 1.15), but in winter were higher among ANA-positives (50.2 vs. 20.1 ANA-negative; GM ratio 2.50). ANA was associated with log10BP-3 in winter (POR 1.57; 95%CI 1.07-2.30 per unit increase) but not summer (0.94; 0.61, 1.44; interaction p=0.09). Triclosan, parabens, and bisphenol-A levels were unrelated to ANA overall or by season (ORs 0.64 to 1.33).ConclusionsThe association of urinary BP-3 with ANA in the winter may reflect different exposure patterns or unmeasured confounders. Findings warrant replication in prospective studies and including past and year-round exposures.
