RESUMO
OBJECTIVE: Substantial data on COVID-19-related morbidity and mortality among medically underserved populations are available, yet data on the social impact of the COVID-19 pandemic among immigrants in the United States are limited. We identified COVID-19-related health and social disparities among US immigrants. METHODS: We analyzed predictors of COVID-19-related health and social outcomes (including ever had or thought had COVID-19, vaccine uptake, risk-reduction behaviors, job loss, childcare difficulties, and difficulty paying rent) during the pandemic by citizenship status, using data from the 2021 California Health Interview Survey. The overall sample size included 24 453 US-born citizens, naturalized citizens, and noncitizens aged ≥18 years. We examined relationships between sociodemographic variables, including immigration-related factors, and COVID-19-related health and social outcomes using descriptive, bivariate, and multivariate logistic regression analysis. RESULTS: When accounting for sociodemographic characteristics, noncitizens had higher odds than naturalized and US-born citizens of experiencing challenges during the COVID-19 pandemic, including difficulty paying rent (adjusted odds ratio [aOR] = 1.54; 95% CI, 1.47-2.42) and job loss (aOR = 1.43; 95%, CI, 1.14-1.79). At the bivariate level, noncitizens had the highest rate of ever had or thought had COVID-19 (24.7%) compared with US-born citizens (20.8%) and naturalized citizens (16.8%; all P < .001). Noncitizens also had a significantly higher likelihood of risk-reduction behaviors (eg, always wearing a face covering, getting vaccinated if available) than US-born citizens (P < .001). CONCLUSION: These findings reveal the disproportionate impact of the COVID-19 pandemic among noncitizens and reflect limited socioeconomic resources, limited access to health care, and precarious employment among noncitizens in California during the pandemic. Citizenship status should be considered a critical immigration-related factor when examining disparities among immigrant populations.

BACKGROUND: Older adults' engagement on social media may be a resource to reduce loneliness and improve mental health. PURPOSE: This study aimed to examine loneliness and social media use and its association with severe psychological distress among older adults and whether social media use moderated the association of loneliness on severe psychological distress among older adults. METHODS: This study is a secondary analysis of the 2019-2020 California Health Interview Survey. The Kessler 6-item Psychological Distress Scale (K6) assessed symptoms of psychological distress, with a K6 score ≥ 13 associated with severe mental illness. Loneliness was measured using a revised Three Item Loneliness Scale (TILS) score. Multiple regression analyses were conducted to examine associations between loneliness and severe psychological distress. RESULTS: Loneliness, health status, and identification as Asian, remained strong predictors of severe psychological distress among older adults when adjusting for other factors. In bivariate analysis, high-frequent social media users, but did not remain significant when accounting for covariates. Social media use did not moderate the association between loneliness and severe psychological distress. CONCLUSION: This study underscores the significant impact of loneliness on poor mental health among older adults, emphasizing that while frequent social media use correlates with severe psychological distress, it may not alleviate the association of loneliness on poor mental health, thus highlighting the urgent need to address social isolation and promote genuine social connectedness, particularly among Asian older adults.
RESUMO
Background: Although effective antihypertensive medications have existed for decades, only about half of the hypertensive individuals are considered to have controlled blood pressure. Limited research studies have investigated gender disparity in the utilization and effectiveness of antihypertensive medications treatment. To examine the gender difference in antihypertensive medications' use and the effect of using antihypertensive medication treatment on blood pressure control among the U.S. adult with hypertension. Methods: Analysis of National Health and Nutrition Examination Survey (NHANES) data from (1999-2012) including individuals≥18 years old with hypertension. Study variables included gender, age, race/ethnicity, obesity, smoking, comorbidities, treatment medication type, and continuity of care. We used multivariate logistic regression in STATA V14. The data is presented as adjusted odds ratios (ORs) and 95% confidence interval (CI). Results: Of the 15719 participants, 52% were female. 49% of the antihypertensive medication users had their blood pressure under control (95% CI). In the adjusted logistic regression analysis, use of antihypertensive medications was found to be 12% greater in females as compared to males (OR=1.12; CI=1.02-1.22; P<0.05). No association between gender and blood pressure control was found. Blood pressure control was less likely achieved among 50 years or younger individuals, Blacks and Hispanics, obese, and those taking calcium channel blocker (CCB). Conclusion: Hypertensive females are more likely than males to use antihypertensive medications. The effectiveness of treatment to control blood pressure is equal across males and females. Our findings have implications for practitioners to account gender-specific approaches when discussing adherence to hypertension medication treatment with their patients.
RESUMO
BACKGROUND: South Los Angeles (SPA6), with mostly Black (27.4%) and Latinx (68.2%) residents, has the second highest rates of new HIV diagnoses (31 per 100,000) in Los Angeles County. However, there is limited understanding of the HIV testing-to-care continuum among newly diagnosed in this setting. METHODS: We conducted an exploratory study that analyzed de-identified data, including demographic characteristics and biomedical outcomes, from the electronic medical records of individuals newly diagnosed with HIV from 2016-2020 at the only public safety-net, county-run health department HIV clinic in SPA 6. We used Pearson Chi-square and Fisher's Exact test to explore associations with HIV outcomes and a Kaplan-Meier survival curve to assess the time to linkage to care. RESULTS: A total of 281 patients were identified. The majority (74.1%) presented with a baseline CD4 <500, many of which presented with a CD4<200 (39.2%). We found twice as many newly diagnosed Black individuals in our study population (48.2%) when compared to LAC (23%), despite only accounting for 27.4% of residents in SPA 6. The majority were linked to care within 30 days of positive test and prescribed anti-retroviral therapy. Viral suppression (59.8%) and undetectable VL (52.6%) were achieved within the year following diagnosis, with 9.3% lost to follow-up. Of those who became virally suppressed, 20.7% experienced viral rebound within the year following diagnosis. CONCLUSION: The large proportion of patients with a baseline CD4 <500 raises concerns about late diagnoses. Despite high rates of linkage to care and ART prescription, achievement of sustained viral suppression remains low with high rates of viral rebound. Longitudinal studies are needed to understand the barriers to early testing, retention in care, and treatment adherence to develop strategies and interventions with community organizations that respond to the unique needs of people living with HIV in South Los Angeles.

OBJECTIVE: Clinical guidelines recommend annual eye examinations to detect diabetic retinopathy (DR) in patients with diabetes. However, timely DR detection remains a problem in medically underserved and under-resourced settings in the United States. Machine learning that identifies patients with latent/undiagnosed DR could help to address this problem. MATERIALS AND METHODS: Using electronic health record data from 40 631 unique diabetic patients seen at Los Angeles County Department of Health Services healthcare facilities between January 1, 2015 and December 31, 2017, we compared ten machine learning environments, including five classifier models, for assessing the presence or absence of DR. We also used data from a distinct set of 9300 diabetic patients seen between January 1, 2018 and December 31, 2018 as an external validation set. RESULTS: Following feature subset selection, the classifier with the best AUC on the external validation set was a deep neural network using majority class undersampling, with an AUC of 0.8, the sensitivity of 72.17%, and specificity of 74.2%. DISCUSSION: A deep neural network produced the best AUCs and sensitivity results on the test set and external validation set. Models are intended to be used to screen guideline noncompliant diabetic patients in an urban safety-net setting. CONCLUSION: Machine learning on diabetic patients' routinely collected clinical data could help clinicians in safety-net settings to identify and target unscreened diabetic patients who potentially have undiagnosed DR.
RESUMO
There is high HIV prevalence and low rates of viral suppression for men who have sex with men (MSM) in South Africa, with few MSM-centered interventions to address these outcomes along the HIV treatment cascade. Participatory interventions may support community building among HIV-positive MSM through which they can share approaches of self-advocacy that are contextually grounded. We conducted a pilot study to assess the use of role-plays in influencing social isolation while also updating our understanding of MSM healthcare experiences in Mpumalanga, South Africa. The study was conducted with 21 MSM leaders who were HIV-positive. There were three groups of seven participants each who created and performed role-plays based on their healthcare experiences, with a focus group discussion (FGD) conducted afterward. Audio-recordings were transcribed, translated, and analyzed using a constant comparison approach. We found that MSM described role-play as cathartic and a future HIV care educational tool for other MSM, and that they outlined points of self-advocacy during HIV care in clinics. Our study suggests that future research should utilize role-play so to integrate contextual factors influencing HIV treatment, especially in high HIV prevalence settings.

Self-inflicted harm (SIH) has a substantial lifetime prevalence, it is associated with tremendous costs, and its rate is increasing on a national scale. To examine the characteristics of those admitted for SIH in the US and to investigate the factors that potentially modify the methods used for SIH. This was a retrospective analysis of admitted cases of SIH including suicide attempts between 2007 and 2012 using the National Trauma Data Bank. We included a total of 204,633 cases admitted for SIH. Our participants were 75.1% males. Those aged 15-24 (21%), 25-34 (22%), 35-44 (19%), 45-54 (19%), and 55-64 (10%) years comprised the largest age groups among our cases-70.8%, 11.5%, 11.1%, and 6.6% were, respectively, Caucasians, Hispanics, Blacks, and Asian/Others. Analyses of the SIH methods revealed that Blacks were less likely to self-poison [Odds Ratio (OR): 0.78] compared to Whites, whereas individuals with psychiatric disorders or substance abuse carried 2.5 and 2.0-fold higher risk, respectively. Blacks were also less likely to use anoxic methods (OR: 0.69), whereas patients with psychiatric disorders or substance abuse carried 1.5-fold higher risk. Being Black, Hispanic, and Asian (OR: 0.58, 0.55, and 0.55, respectively) as well as having psychiatric disorders (OR: 0.80) were associated with lower risks of using firearms, whereas its risk was increased with increasing age. Blacks (OR: 0.77) were less likely to cut or pierce in contrast to Hispanics (OR: 1.4), Asians/Others (OR: 1.29), and those with psychiatric disorders (2.5-fold higher risk) or drug abuse (2-fold higher risk). Blacks (OR: 1.11), Hispanics (OR: 1.13), and Asians/Others (OR: 1.57) were more likely to jump from high places, whereas those with substance abuse were less likely (OR: 0.77). Among patients admitted for SIH, males, those aged 15-64 years, and Whites comprised the largest sex, age, and racial/ethnic groups, respectively. We also found that several factors including race/ethnicity, gender, age, and having concurrent psychiatric or drug abuse disorders can potentially influence the methods used for SIH.

BACKGROUND: The objectives of this study are 1) to depict the prevalence of moderate depressive symptoms (MDS) in adolescents living in California, 2) to examine the role of acculturation in reported MDS, and 3) to identify any relationship between acculturation, "needing emotional help," and "receiving psychological or emotional counseling," as reported by adolescents with MDS. METHODS: We analyzed data from a cross-sectional population-based telephone survey for adolescents who completed the California Health Interview Survey (CHIS) in 2007, 2009, and 2011-2012. The primary predictor variable was level of acculturation. Outcome variables were 1) the presence of MDS, 2) whether participants needed help with emotional problems, and 3) whether they had received psychological or emotional counseling. RESULTS: Of the sample (n = 9816), 6.0% had MDS; 50% of these reported needing help for emotional problems, and 30% reported receiving psychological/emotional counseling. Multivariate analysis that included the interaction effects of race/ethnicity and acculturation showed that the latter was not associated with any of the outcome variables. However, Latino adolescent with MDS and moderate acculturation were less likely to report needing help for psychological/emotional problems, compared to their White counterparts with higher acculturation. CONCLUSION: Our findings suggest disparities in reporting depression symptoms and receiving psychological/emotional help are not driven by adolescents' acculturation levels. However, more studies are needed to clarify what cultural factors facilitate or inhibit moderately acculturated Latino adolescents from reporting needing help for psychological/emotional problems.
RESUMO
The objective of this study was to investigate the effectiveness of using decision support instruments (DSI) to assist African-American (AA) men in making a prostate cancer (CaP) screening decision. This nonrandomized pretest-posttest comparison study assessed two DSI that were either culturally tailored or culturally nonspecific. CaP knowledge, intention to screen, and preferences were assessed before and after exposure to DSI using a convenience sample of 120 AA men aged 40 years and above. Participants interested in screening were referred to healthcare providers through a community-based patient navigator to obtain prostate-specific antigen (PSA) testing. We followed up 3 months after to determine if participants screened for CaP. CaP knowledge increased following exposure to both DSI in equivalent proportions. While similar proportions of men ultimately intended on having a PSA test following both DSI, bivariate analysis revealed that the culturally tailored DSI demonstrated a statistically significant increase in intention to screen. Participants' degree of certainty in their decision-making process with regard to CaP screening increased following the culturally tailored DSI (p < .001). The majority of participants planned on discussing CaP screening with a healthcare provider upon completion of the study. Barbershop-based health education can change the knowledge, preferences, intentions, and behaviors of this at-risk population. At 3 months follow-up, half (n = 58) of the participants underwent PSA testing, which led to the diagnosis of CaP in one participant. Community-led interventions for CaP, such as cluster-randomized designs in barbershops, are needed to better assess the efficacy of DSI in community settings.

INTRODUCTION: Screening guidelines for diabetic patients recommend yearly eye examinations to detect diabetic retinopathy and other forms of diabetic eye disease. However, annual screening rates for retinopathy in US urban safety net settings remain low. METHODS: Using data gathered from a study of teleretinal screening in six urban safety net clinics, we assessed whether predictive modeling could be of value in identifying patients at risk of developing retinopathy. We developed and examined the accuracy of two predictive modeling approaches for diabetic retinopathy in a sample of 513 diabetic individuals, using routinely available clinical variables from retrospective medical record reviews. Bayesian networks and radial basis function (neural) networks were learned using ten-fold cross-validation. RESULTS: The predictive models were modestly predictive with the best model having an AUC of 0.71. DISCUSSION: Using routinely available clinical variables to predict patients at risk of developing retinopathy and to target them for annual eye screenings may be of some usefulness to safety net clinics.

OBJECTIVE: Teleretinal screening with nonmydriatic cameras has been presented as a means of increasing the number of patients assessed for diabetic retinopathy in urban safety net clinics. It has been hypothesized that automated nonmydriatic cameras may improve screening rates by reducing the learning curve for camera use. In this article, we examine the impact of introducing automated nonmydriatic cameras to urban safety net clinics whose photographers had previously used manual cameras. MATERIALS AND METHODS: We evaluated the impact of manual and automated digital nonmydriatic cameras on teleretinal screening using a quantitative analysis of readers' image quality ratings as well as a qualitative analysis, through in-depth interviews, of photographers' experiences. RESULTS: With the manual camera, 68% of images were rated "adequate" or better, including 24% rated "good" and 20% rated "excellent." With the automated camera, 61% were rated "adequate" or better, including 9% rated "good" and 0% rated "excellent." Photographers expressed frustration with their inability to control image-taking settings with the automated camera, which led to unexpected delays. CONCLUSIONS: For safety net clinics in which medical assistants are already trained to take photographs for diabetic retinopathy screening with a manual camera, the introduction of automated cameras may lead to frustration and paradoxically contribute to increased patient wait times. When photographers have achieved a high degree of aptitude with manual cameras and value the control they have over camera features, the introduction of automated cameras should be approached with caution and may require extensive training to increase user acceptability.

UNLABELLED: Obesity, a risk factor for hypertension, diabetes, and other chronic diseases is influenced by geographic accessibility to supermarkets, which has been shown to affect nutritional behaviors. PURPOSE: To determine how individual fruit and vegetable (FV) consumption was independently influenced by accessibility to supermarkets, and to quantify that relationship. METHODS: A distance decay based model was specified for a random sample (n=7,514) of urban residents. Associations between FV consumption and accessibility to supermarkets were explored, controlling for factors known to influence eating behaviors. RESULTS: There was as independent effect of accessibility to supermarkets, even after the inclusion of the significant controlling factors of age, gender, race/ethnicity, education, marital status, and knowledge of nutritional guidelines. CONCLUSION: Our model of accessibility was an effective predictor of FV consumption in an urban population, setting the stage for inclusion of supply and demand parameters, and estimation of local factors that contribute to differential obesity rates.

In a previous paper, we presented initial findings from a study on the feasibility and challenges of implementing teleretinal screening for diabetic retinopathy in an urban safety net setting facing eyecare specialist shortages. This paper presents some final results from that study, which involved six South Los Angeles safety net clinics. A total of 2,732 unique patients were screened for diabetic retinopathy by three ophthalmologist readers, with 1035 receiving a recommendation for referral to specialty care. Referrals included 48 for proliferative diabetic retinopathy, 115 for severe non-proliferative diabetic retinopathy (NPDR), 247 for moderate NPDR, 246 for mild NPDR, 97 for clinically significant macular edema, and 282 for a non-diabetic condition, such as glaucoma. Image quality was also assessed, with ophthalmologist readers grading 4% to 13% of retinal images taken at the different clinics as being inadequate for any diagnostic interpretation.

Diabetic retinopathy is a leading cause of blindness in US adults. This paper presents initial results of a teleretinal screening project for diabetic retinopathy involving six Los Angeles safety net clinics. A total of 1,943 patients have been screened for diabetic retinopathy by three ophthalmologist readers, with 416 receiving a recommendation for referral to specialty care. Of the cases recommended for referral, 24 had proliferative diabetic retinopathy, 62 had severe non-proliferative diabetic retinopathy (NPDR), 60 had moderate NPDR, 19 had mild NPDR, 138 had a non-diabetic condition, such as glaucoma, 63 had clinically significant macular edema without retinopathy and 50 had non-gradable images. Between 3% and 12.2% of retinal images taken at the clinics were assessed by readers as inadequate for any interpretation. The study shows the feasibility and challenges of teleretinal screening for diabetic retinopathy in urban areas facing specialist shortages and an overburdened, under-resourced safety net care-delivery system.

BACKGROUND: Literature documentation of the health consequences of obesity among adolescents continues to grow and includes the psychosocial consequences of obesity on this population. OBJECTIVE: The specific aim of this study was to identify prevalence of depression in adolescents, aged 12 to 17 years, and to identify the role of overweight as a risk factor for depression. METHODS: Secondary data analysis of the adolescent version of the 2005 California Health Interview Survey. Symptoms of depression were measured with a reduced version of the Center for Epidemiologic Studies Depression Scale. Weight status was determined using the Centers for Disease Control definitions and those recommended by the American Academy of Pediatrics. RESULTS: The sample was nearly half male (50.6%). The majority of the adolescents in the sample were White (47.2%) followed by Latino (33.5%). Approximately 10% of the adolescents reported more than 10 depression symptoms. Based on BMI, 16.5% of the sample were at-risk of being overweight, and 14.7% were overweight. However, 24.4% of sample thought they were 'slightly overweight or very overweight. We did not find any statistically significant association between weight status and symptoms of depression, but at the bivariate level we did find a statistically significant association between perception of one's weight and depression, P < .001. We also found that sex (OR 3.10; CI 2.07-4.51), perceived health (OR 2.25; CI 1.53-3.31), smoking (OR 1.8; CI 1.30-2.69), and alcohol use (OR 2.06; CI 1.44-2.95) were independently associated with depression symptoms. CONCLUSION: Even though we were unable to prove the proposed association, our findings are noteworthy given that the association between these variables are less clear in the literature. Future studies that attempt to examine the relationship between these two variables may benefit from longitudinal design, inclusion of multi-item risk and protective predictors, inclusion of social-context related variables, perceived weight, and family history of obesity.

The presence of street gangs has been hypothesized as influencing overall levels of violence in urban communities through a process of gun-drug diffusion and cross-type homicide. This effect is said to act independently of other known correlates of violence, i.e., neighborhood poverty. To test this hypothesis, we independently assessed the impact of population exposure to local street gang densities on 8-year homicide rates in small areas of Los Angeles County, California. Homicide data from the Los Angeles County Coroners Office were analyzed with original field survey data on street gang locations, while controlling for the established covariates of community homicide rates. Bivariate and multivariate regression analyses explicated strong relationships between homicide rates, gang density, race/ethnicity, and socioeconomic structure. Street gang densities alone had cumulative effects on small area homicide rates. Local gang densities, along with high school dropout rates, high unemployment rates, racial and ethnic concentration, and higher population densities, together explained 90% of the variation in local 8-year homicide rates. Several other commonly considered covariates were insignificant in the model. Urban environments with higher densities of street gangs exhibited higher overall homicide rates, independent of other community covariates of homicide. The unique nature of street gang killings and their greater potential to influence future local rates of violence suggests that more direct public health interventions are needed alongside traditional criminal justice mechanisms to combat urban violence and homicides.

OBJECTIVES: To compare the percentage of diabetics admitted to the hospital due to hypoglycemia in 1990-1993 (period 1) to that in 1997-2000 (period 2). METHODS: We analyzed data from the California Hospital Discharge Data Program. Eligibility included diabetic (ICD code 250) subjects aged > or =25 years old who were hospitalized due to hypoglycemia (ICD Codes 250.8) during the periods 1990-1993 and 1997-2000. Data were analyzed by demographics and health insurance status. RESULTS: Of the 2,905,091 hospitalized diabetics, 50,017 (1.7%) were due to hypoglycemia. The percentage of hospitalization due to hypoglycemic varied by sex, age, race/ethnicity, and insurance status (P = .0001). Male, Hispanic, age 25-64 years, with Medical/Medicare insurance had higher odds of being hospitalized due to hypoglycemia relative to other groups (P < .001). The percentage of diabetics hospitalized due to hypoglycemia increased from period 1 to period 2 (1.3% vs. 2.0%, P = .0001). Diabetics hospitalized in period 2 had higher adjusted odds of being hospitalized due to hypoglycemia relative to those admitted in period 1 (OR = 1.6, P < .0001). CONCLUSION: Our data show an increase in the hospitalization due to hypoglycemia in diabetic patients. Enhanced patient education about self-monitoring of blood sugar and recognizing and treating the symptoms of hypoglycemia may help to minimize hypoglycemic hospitalizations.

Studies have shown that hepatitis C (HCV) is associated with type 2 diabetes mellitus (DM2) possibly due to insulin resistance and inflammation. Metabolic syndrome is a risk factor for DM2. Our objectives were to assess the relationship between HCV and metabolic syndrome and inflammatory markers. We used data from The Third National Health Nutrition and Examination Survey (NHANES-III). We excluded pregnant women, subjects with diabetes, those taking non-steroidal anti-inflammatory drugs, and those diagnosed with concomitant infection. We analyzed the data controlling for demographic variables, body mass index, use of contraceptives, had arthritis, and had gout. Among the 10,383 subjects, 2.3% had HCV and 16.7% had metabolic syndrome using the ATP III criteria. After controlling for the confounders, HCV was not associated with metabolic syndrome but associated with HOMA insulin resistance and inflammatory marker ferritin. Among subjects with both HCV and metabolic syndrome, the adjusted HOMA insulin level was higher than those without HCV and metabolic syndrome. In addition, the serum ferritin level was a strong predictor of HOMA insulin resistance. In clinical practice, serum ferritin can be obtained along with routine blood tests in any laboratory, and it has a potential to be a surrogate marker of insulin resistance in people with HCV and metabolic syndrome.

OBJECTIVE: Inflammatory cytokines have been shown to play an important role in bone remodeling. We hypothesized that higher levels of C-reactive protein (CRP) are associated with low bone mineral density (BMD) in elderly females. DESIGN: Secondary data analysis of the Third National Health and Nutrition Examination Survey. PARTICIPANTS: 2,807 females 65 years and older. RESULTS: CRP was associated with BMD in the bivariate sis (p<0.001) but not in the multivariate analysis (p=0.23) Age, ethnicity, body mass index (BMI), hormone replacement therapy (HRT) and immobility were independently associated with BMD. CONCLUSIONS: CRP may be useful in screening for osteoporosis among community-dwelling elderly females. However, CRP appears to act as a surrogate for other factorsdirectly associated with osteoporosis. Further studies are needed to validate these findings.

OBJECTIVES: Minority women are less likely to use hormone replacement therapy (HRT), and the health characteristics associated with HRT use in this population are not well studied. We sought to examine the sociodemographic characteristics, health and preventive practices associated with HRT use among minority women. DESIGN: Survey SETTING: Inpatient and outpatient units of a teaching hospital. PARTICIPANTS: A convenience sample of 333 minority women aged 50 and above. VARIABLES: HRT use, demographic and lifestyle characteristics, and selected preventive practices. RESULTS: 14% of the study population, all minority women were using HRT. Regular exercise (p=0.03), and good perceived health status (p=0.02) were significant predictors of HRT use. None of the cancer screening measures studied were associated with HRT use. CONCLUSIONS: Only a small proportion of minority women were using HRT. Regular exercise and perceived good health were significant predictors of HRT use.
