Comparison of the accumulation of toxic metal biomarkers in Asian subgroups and other races in the United States: NHANES 2015-2016.

Toxic metals such as lead (Pb), cadmium (Cd), mercury (Hg) and arsenic (As) that lead to many visceral organ and nervous system diseases have attracted global attention due to their gradual accumulation in human bodies. The tolerance levels of exposure to toxic metals among race/ethnic groups are different due to the variance of sociodemographic, dietary, and behavioral characteristics. Few studies focused on investigating the biomarker levels of toxic metals in different race/ethnic groups and the potential mechanisms for controlling the accumulation in human bodies. Therefore, we selected eight biomarkers for four toxic metals from the National Health and Nutrition and Examination Survey (NHANES) in the 2-year data cycle of 2015-2016 to reveal the accumulation levels in different races. According to the NHANES rules, we applied probability sampling weights. The geometric mean levels of these biomarkers were calculated in all five race/ethnic groups (Mexican American, white, black, Asian, and other Hispanic) and two Asian subgroups (U.S.-born Asian, and other-born Asian), and compared with each other. The results showed that all the biomarkers in other-born Asians were 1.1-6.7 times in blood and 1.1-3.6 times in urine higher than other race/ethnic groups. Except Hg and As, the lowest biomarker levels were recorded in U.S.-born Asians, only 0.6-0.9 times of lead and 0.3-0.8 times of cadmium than other race/ethnic groups. Furthermore, the major factors of higher Hg and As biomarker levels in Asians were dietary intake of seafood and rice, indicating different accumulation mechanisms among Asians and other race/ethnic groups, especially for U.S.-born Asians. These findings provided new insight into a deeper understanding the accumulation of toxic metals and human health.

Eligibility criteria and enrollment of a diverse racial and ethnic population in multiple myeloma clinical trials.

The narrow eligibility criteria may contribute to the underrepresentation of racial and ethnic subgroups in cancer clinical trials. We conducted a retrospective pooled analysis of multicenter global clinical trials submitted to the US Food and Drug Administration between 2006 and 2019 to support the approval of the use of multiple myeloma (MM) therapies that analyze the rates and reasons for trial ineligibility based on race and ethnicity in MM clinical trials. Race and ethnicity were coded per Office of Management and Budget standards. Patients flagged as having screen failures were identified as ineligible. Ineligibility rates were calculated as the percentage of patients who were ineligible compared with the screened population within the respective racial and ethnic subgroups. Trial eligibility criteria were grouped into specific categories to analyze the reasons for trial ineligibility. Black patients (24%) and other (23%) race subgroups had higher ineligibility rates than White patients (17%). The Asian race had the lowest ineligibility rate (12%) among all racial subgroups. Failure to meet the hematologic laboratory criteria (19%) and treatment-related criteria (17%) were the most common reasons for ineligibility among Black patients and were more common in Black patients than in other races. Failure to meet disease-related criteria was the most common reason for ineligibility among White (28%) and Asian (29%) participants. Our analysis indicates that specific eligibility criteria may contribute to enrollment disparities for racial and ethnic subgroups in MM clinical trials. However, the small number of screened patients in the underrepresented racial and ethnic subgroups limits definitive conclusions.

Using Point-in-Time Homeless Counts to Monitor Mortality Trends Among People Experiencing Homelessness in Los Angeles County, California, 2015‒2019.

Objectives. To report trends in mortality rates, mortality rate ratios (MRRs), and causes of death among people experiencing homelessness (PEH) in Los Angeles County, California, by using annual point-in-time homeless counts and to compare findings to published longitudinal cohort studies of homeless mortality. Methods. We enumerated homeless deaths and determined causes by using 2015-2019 medical examiner‒coroner data matched to death certificate data. We estimated midyear homeless population denominators by averaging consecutive January point-in-time homeless counts. We used annual demographic surveys of PEH to estimate age- and gender-adjusted MRRs. We identified comparison studies through a literature review. Results. Mortality rates increased from 2015 to 2019. Drug overdose was the leading cause of death. Mortality was higher among White than among Black and Latino PEH. Compared with the general population, MRRs ranged from 2.8 (95% confidence interval [CI] = 2.7, 3.0) for all causes to 35.1 (95% CI = 31.9, 38.4) for drug overdose. Crude mortality rates and all-cause MRRs from comparison cohort studies were similar to those in the current study. Conclusions. These methods can be adapted by other urban jurisdictions seeking to better understand and reduce mortality in their homeless populations.

Visual impairment and blindness in the Xingu Indigenous Park - Brazil.

BACKGROUND: Most estimates of visual impairment and blindness worldwide do not include data from specific minority groups as indigenous populations. We aimed to evaluate frequencies and causes of visual impairment and blindness in a large population sample from the Xingu Indigenous Park. METHODS: Cross-sectional study performed at Xingu Indigenous Park, Brazil, from 2016 to 2017. Residents from 16 selected villages were invited to participate and underwent a detailed ocular examination, including uncorrected (UVA) and best-corrected visual acuity (BCVA). The main cause of UVA < 20/32 per eye was determined. RESULTS: A total of 2,099 individuals were evaluated. Overall, the frequency of visual impairment and blindness was 10.00% (95% CI: 8.72-11.29%) when considering UVA, decreasing to 7.15% (95% CI: 6.04-8.25%) when considering BCVA. For each increasing year on age, the risk  of being in the visually impaired or blind category increased by 9% (p < 0.001). Cataracts (39.1%) and uncorrected refractive errors (29.1%) were the most frequent causes of visual impairment and blindness in this population. The main causes among those aged 45 years and more were cataracts (54.5%) while refractive errors were the main cause in adults aged 18 to 45 years (50.0%) and children up to 18 years old (37.1%). CONCLUSIONS: A higher frequency of visual impairment and blindness was observed in the indigenous population when compared to worldwide estimates with most of the causes being preventable and/or treatable. Blindness prevention programs should focus on accessibility to eye exam, cataract surgeries and eyeglass distribution.

The Surgeon's Role in Addressing Racism and Achieving Health Equity.

In the United States, the nation's health is not an organic outcome. It is not a coincidence that certain groups of people living in the United States experience higher premature death rates or poorer health outcomes than others. For centuries, racial and ethnic as well as geographic differences in health outcomes have been part of the American landscape, so entrenched in society that many people fail to recognize that health inequities were intentionally derived. A national crisis tends to magnify inequities in our society, but even more alarming is the fact that as the country becomes more racially and ethnically diverse in the coming years, the health inequities are projected to worsen if we do not proactively and immediately address them. As we continue to grapple with the lasting impact of the pandemic, it is of vital importance that we utilize this time to acknowledge, understand, and seriously address the health inequities that have historically plagued the country for over 400 years. As the United States works overtime to stem the tide of the COVID-19 pandemic, it must also work equally hard to move in a more equitable, inclusive, and healthier direction, not only because of the more than 83 000 Americans dying prematurely each year but also because of the economic and national security toll it will have if not effectively addressed.

Relation of prior statin and anti-hypertensive use to severity of disease among patients hospitalized with COVID-19: Findings from the American Heart Association's COVID-19 Cardiovascular Disease Registry.

BACKGROUND: Statins have anti-inflammatory and immunomodulatory effects that may reduce the severity of coronavirus disease 2019 (COVID-19), in which organ dysfunction is mediated by severe inflammation. Large studies with diverse populations evaluating statin use and outcomes in COVID-19 are lacking. METHODS AND RESULTS: We used data from 10,541 patients hospitalized with COVID-19 through September 2020 at 104 US hospitals enrolled in the American Heart Association's COVID-19 Cardiovascular Disease (CVD) Registry to evaluate the associations between statin use and outcomes. Prior to admission, 42% of subjects (n = 4,449) used statins (7% on statins alone, 35% on statins plus anti-hypertensives). Death (or discharge to hospice) occurred in 2,212 subjects (21%). Outpatient use of statins, either alone or with anti-hypertensives, was associated with a reduced risk of death (adjusted odds ratio [aOR] 0.59, 95% CI 0.50-0.69), adjusting for demographic characteristics, insurance status, hospital site, and concurrent medications by logistic regression. In propensity-matched analyses, use of statins and/or anti-hypertensives was associated with a reduced risk of death among those with a history of CVD and/or hypertension (aOR 0.68, 95% CI 0.58-0.81). An observed 16% reduction in odds of death among those without CVD and/or hypertension was not statistically significant. CONCLUSIONS: Patients taking statins prior to hospitalization for COVID-19 had substantially lower odds of death, primarily among individuals with a history of CVD and/or hypertension. These observations support the continuation and aggressive initiation of statin and anti-hypertensive therapies among patients at risk for COVID-19, if these treatments are indicated based upon underlying medical conditions.

Trends in COVID-19 case-fatality rates in Brazilian public hospitals: A longitudinal cohort of 398,063 hospital admissions from 1st March to 3rd October 2020.

BACKGROUND: Almost 200,000 deaths from COVID-19 were reported in Brazil in 2020. The case fatality rate of a new infectious disease can vary by different risk factors and over time. We analysed the trends and associated factors of COVID-19 case fatality rates in Brazilian public hospital admissions during the first wave of the pandemic. METHODS: A retrospective cohort of all COVID-19-related admissions between epidemiological weeks 10-40 in the Brazilian Public Health System (SUS) was delimited from available reimbursement records. Smoothing time series and survival analyses were conducted to evaluate the trends of hospital case fatality rates (CFR) and the probability of death according to factors such as sex, age, ethnicity, comorbidities, length of stay and ICU use. RESULTS: With 398,063 admissions and 86,452 (21.7%) deaths, the overall age-standardized hospital CFR trend decreased throughout the period, varying from 31.8% (95%CI: 31.2 to 32.5%) in week 10 to 18.2% (95%CI: 17.6 to 18.8%) in week 40. This decreasing trend was observed in all sex, age, ethnic groups, length of stay and ICU admissions. Consistently, later admission (from July to September) was an independent protective factor. Patients 80+ year old had a hazard ratio of 8.18 (95% CI: 7.51 to 8.91). Ethnicity, comorbidities, and ICU need were also associated with the death risk. Although also decreasing, the CFR was always around 40-50% in people who needed an ICU admission. CONCLUSIONS: The overall hospital CFR of COVID-19 has decreased in Brazilian public hospitals during the first wave of the pandemic in 2020. Nevertheless, during the entire period, the CFR was still very high, suggesting the need for improving COVID-19 hospital care in Brazil.

[Nutritional Study in Spanish Pediatric Population (EsNuPI): updated findings and initial conclusions]. / Estudio Nutricional en Población Infantil Española (EsNuPI): actualización de hallazgos y primeras conclusiones.

INTRODUCTION: Introduction: eating habits and lifestyles during early childhood are important due to their association with chronic diseases in adulthood. Objectives: to evaluate energy and nutrient intake, main food sources, and dietary patterns in the EsNuPI study participants. Methods: a sociodemographic questionnaire, food frequency questionnaire, two 24 h recalls, and a physical activity questionnaire were used in two cohorts of Spanish children aged 1 to < 10 years, who were non-vegans living in municipalities > 50,000 inhabitants - one representative cohort of consumers of all types of milks (SRS = 707) and one other cohort consuming adapted milks (AMS = 741). Results: 84.7 % in SRS and 83.5 % in AMS showed a plausible, adequate energy (EI) (1503 and 1404 kcal/day, respectively). The percentage of children with protein intake > 20 % of EI was 12 % for SRS, and 6 % for AMS. Both cohorts exceeded the recommendations for total fat (36.5 % in SRS, 35.9 % in AMS) and saturated fat (13.1 % vs 12.1 %, respectively); DHA intake was significantly lower in SRS (20 mg vs 90 mg). Vitamin D intake was significantly lower in SRS, although both cohorts did not meet the recommendation. When analyzing dietary patterns, one of palatable energy-dense foods and two of Mediterranean type were highlighted. Conclusions: it is recommended that consumption of saturated fatty acids and protein be reduced, but calcium, vitamin D, and magnesium intakes should be increased, especially in children > 4 years. These findings are important for designing interventions in the Spanish child population. The findings of the EsNuPI study provide useful information for the design and promotion of appropriate interventions for Spanish children.

INTRODUCCIÓN: Introducción: los hábitos de alimentación y los estilos de vida durante las primeras etapas de la infancia son importantes por su asociación a enfermedades crónicas durante la vida adulta. Objetivos: evaluar la ingesta de energía, el aporte de nutrientes, las principales fuentes alimentarias y los patrones dietéticos de los participantes en el estudio EsNuPI. Métodos: se utilizaron un cuestionario sociodemográfico, un cuestionario de frecuencia de consumo de alimentos, dos recuerdos de 24 h y un cuestionario de actividad física en dos cohortes de niños españoles de 1 a < 10 años, no veganos, residentes en municipios > 50.000 habitantes: una representativa de los consumidores de todo tipo de leches (SRS = 707) y otra consumidora de leches adaptadas (AMS = 741). Resultados: el 84,7 % de la cohorte SRS y el 83,5 % de la AMS mostraron una ingesta energética (IE) plausible y adecuada (1503 y 1404 kcal/día, respectivamente) en ambas cohortes. El porcentaje de niños con ingesta proteica > 20 % de la IE fue del 12 % en la SRS y el 6 % en la AMS. Ambas cohortes sobrepasaron las recomendaciones de grasa total (36,5 % en la SRS; 35,9 % en la AMS) y de grasas saturadas (13,1 % vs. 12,1 %, respectivamente); la ingesta de DHA fue significativamente menor en la SRS (20 mg/d vs. 90 mg/d). La ingesta de vitamina D fue significativamente menor en la SRS, aunque ambas cohortes no alcanzaron las recomendaciones de los organismos internacionales. Al analizar los patrones alimentarios, destacan uno de alimentos apetitosos e hipercalóricos y dos de tipo mediterráneo. Conclusiones: es recomendable reducir la ingesta de grasas saturadas y proteínas, e incrementar la de calcio, vitamina D y magnesio, esto último especialmente en los niños > 4 años. Estos hallazgos son importantes para el diseño de intervenciones en la población infantil española.

Phylogenetic Networks and Parameters Inferred from HIV Nucleotide Sequences of High-Risk and General Population Groups in Uganda: Implications for Epidemic Control.

Phylogenetic inference is useful in characterising HIV transmission networks and assessing where prevention is likely to have the greatest impact. However, estimating parameters that influence the network structure is still scarce, but important in evaluating determinants of HIV spread. We analyzed 2017 HIV pol sequences (728 Lake Victoria fisherfolk communities (FFCs), 592 female sex workers (FSWs) and 697 general population (GP)) to identify transmission networks on Maximum Likelihood (ML) phylogenetic trees and refined them using time-resolved phylogenies. Network generative models were fitted to the observed degree distributions and network parameters, and corrected Akaike Information Criteria and Bayesian Information Criteria values were estimated. 347 (17.2%) HIV sequences were linked on ML trees (maximum genetic distance ≤4.5%, ≥95% bootstrap support) and, of these, 303 (86.7%) that consisted of pure A1 (n = 168) and D (n = 135) subtypes were analyzed in BEAST v1.8.4. The majority of networks (at least 40%) were found at a time depth of ≤5 years. The waring and yule models fitted best networks of FFCs and FSWs respectively while the negative binomial model fitted best networks in the GP. The network structure in the HIV-hyperendemic FFCs is likely to be scale-free and shaped by preferential attachment, in contrast to the GP. The findings support the targeting of interventions for FFCs in a timely manner for effective epidemic control. Interventions ought to be tailored according to the dynamics of the HIV epidemic in the target population and understanding the network structure is critical in ensuring the success of HIV prevention programs.

Need for Ethnic and Population Diversity in Psychosis Research.

This article aims to evaluate "racial", ethnic, and population diversity-or lack thereof-in psychosis research, with a particular focus on socio-environmental studies. Samples of psychosis research remain heavily biased toward Western, Educated, Industrialized, Rich, and Democratic (WEIRD) societies. Furthermore, we often fail to acknowledge the lack of diversity, thereby implying that our findings can be generalized to all populations regardless of their social, ethnic, and cultural background. This has major consequences. Clinical trials generate findings that are not generalizable across ethnicity. The genomic-based prediction models are far from being applicable to the "Majority World." Socio-environmental theories of psychosis are solely based on findings of the empirical studies conducted in WEIRD populations. If and how these socio-environmental factors affect individuals in entirely different geographic locations, gene pools, social structures and norms, cultures, and potentially protective counter-factors remain unclear. How socio-environmental factors are assessed and studied is another major shortcoming. By embracing the complexity of environment, the exposome paradigm may facilitate the evaluation of interdependent exposures, which could explain how variations in socio-environmental factors across different social and geographical settings could contribute to divergent paths to psychosis. Testing these divergent paths to psychosis will however require increasing the diversity of study populations that could be achieved by establishing true partnerships between WEIRD societies and the Majority World with the support of funding agencies aspired to foster replicable research across diverse populations. The time has come to make diversity in psychosis research more than a buzzword.

Ethnic disparities in COVID-19 mortality in Mexico: A cross-sectional study based on national data.

INTRODUCTION: Across the world, the COVID-19 pandemic has disproportionately affected racial and ethnic minorities. How ethnicity affects Indigenous peoples in Mexico is unclear. The aim of this cross-sectional study was to determine the mortality associated with ethnicity, particularly of Indigenous peoples, in a large sample of patients with COVID-19 in Mexico. METHODS: We used open access data from the Mexican Ministry of Health, which includes data of all confirmed COVID-19 cases in the country. We used descriptive statistics to compare differences among different groups of patients. Logistic regression was used to calculate odds ratios while adjusting for confounders. RESULTS: From February 28 to August 3, 2020, a total of 416546 adult patients were diagnosed with COVID-19. Among these, 4178 were Indigenous peoples. Among all patients with COVID-19, whether hospitalized or not, a higher proportion of Indigenous peoples died compared to non-Indigenous people (16.5% vs 11.1%, respectively). Among hospitalized patients, a higher proportion of Indigenous peoples died (37.1%) compared to non-Indigenous peoples (36.3%). Deaths outside the hospital were also higher among Indigenous peoples (3.7% vs 1.7%). A higher proportion of Indigenous peoples died in both the private and public health care sectors. The adjusted odds ratio for COVID-19 mortality among Indigenous peoples with COVID-19 was 1.13 (95% confidence interval 1.03 to 1.24). The adjusted odds ratio for COVID-19 mortality among Indigenous peoples with COVID-19 was higher among those who received only ambulatory care (1.55, 95% confidence interval 1.24 to 1.92). DISCUSSION: In this large sample of patients with COVID-19, the findings suggest that Indigenous peoples in Mexico have a higher risk of death from COVID-19, especially outside the hospital. These findings suggest Indigenous peoples lack access to care more so than non-Indigenous people during the COVID-19 pandemic in Mexico.

Programmatic mapping and size estimation of female sex workers, transgender sex workers and men who have sex with men in Istanbul and Ankara, Turkey.

OBJECTIVES: Despite a growing HIV threat, there is no definition and characterisation of key populations (KPs), who could be the major drivers of the epidemic in Turkey. We used programmatic mapping to identify locations where KPs congregate, estimate their numbers and understand their operational dynamics to develop appropriate HIV programme implementation strategies. METHODS: Female and transgender sex workers (FSWs and TGSWs), and men who have sex with men (MSM) were studied in Istanbul and Ankara. Within each district, hot spots were identified by interviewing key informants and a crude spot list in each district was developed. The spot validation process was led by KP members who facilitated spot access and interviews of KPs associated with that spot. Final estimates were derived by aggregating the estimated number of KPs at all spots, which was adjusted for the proportion of KPs who visit multiple spots, and for the proportion of KPs who do not visit spots. RESULTS: FSWs were the largest KP identified in Istanbul with an estimate of 30 447 (5.8/1000 women), followed by 15 780 TGSWs (2.9/1000 men) and 11 656 MSM (2.1/1000). The corresponding numbers in Ankara were 9945 FSWs (5.2/1000 women), 1770 TGSWs (1/1000 men) and 5018 MSM (2.5/1000 men). Each KP had unique typologies based on the way they find and interact with sex partners. MSM were mostly hidden and a higher proportion operated through internet and phone-based applications. Night time was the peak time with Friday, Saturday and Sunday being the peak days of activity in both Istanbul and Ankara. CONCLUSIONS: This study has highlighted the presence of a substantial number of FSWs, TGSW and MSM in Istanbul and Ankara. The information obtained from this study can be used to set priorities for resource allocation and provide HIV prevention services where coverage could be the highest.

Targeting Physical Inactivity - Effects of Three Different Consequence Frames on Population Subgroups' Health-Related Perceptions and Behavioral Intentions.

Physical inactivity constitutes a major health problem in many Western societies affecting a variety of social groups. As these groups often differ in responsivity to physical inactivity messages, the strategy of message targeting, i.e. the customization of messages toward shared characteristics of a social group provides a useful framework for designing effective communication. Whereas focusing on health consequences of physical inactivity might prove useful for some social groups, it might be more effective to emphasize its social or financial consequences for others. The current examination compares the effects of three types of consequence framing (health consequences vs. social consequences vs. financial consequences of physical inactivity) on health-related perceptions and intentions for different population subgroups. An experiment with a one-factorial between subjects design based on a quota sample was conducted. 348 respondents differing in terms of age, sex, and formal education were randomly assigned to one of the three experimental conditions and read an accordingly manipulated newspaper article. Findings show that financial and social consequence frames were more effective than health consequence frames. Both frames positively influenced behavioral intentions through perceptions of susceptibility. These effects were largely independent of sociodemographic variables, although sex and education emerged as moderators in some cases.

[A Meta-analysis on the infection rates on Mycoplasma genitalium in the genitourinary tract of different populations in China].

Objective: Mycoplasma genitalium (Mg) is an opportunity pathogenic microorganism mainly transmitted through sexual contact. In recent years, scholars have paid more attention to Mg infection and pathogenicity. This study was aimed to understand the condition of Mg in the genitourinary tract of different populations in China and provide evidence for further study of its pathogenic characteristics. Methods: Cross-section studies of Mg infection in the Chinese community were searched by China National Knowledge Infrastructure (CNKI), Wanfang digital database, SinoMed, Pubmed, and Web of Science from database construction to March 10th, 2020. Studies were sifted and screened independently by two evaluators based on inclusion and exclusion criteria, and Meta-analysis was conducted with R 1.1.463. If I2≤50%, the fixed-effect model should be adopted, if I2>50%, the random effect model should be adopted, and through subgroup analysis, the source of heterogeneity should be found out as far as possible. Results: A total of 47 research articles were included in this article, all of which were medium and high-quality articles. There was no obvious publication bias, and the results were more reliable. The research contained 19 provinces and Hong Kong Special administrative region, including 519 healthy people, 10 504 patients from clinics or hospitals of sexual transmitted disease (STD), 3 200 on Gynecology and 1 624 on Urology, 1 082 patients with men who have sex with men(MSM), 1 842 patients with Female sex worker(FSW), and 3 691 patients with HIV/AIDS. The infection rate of Mg in the genitourinary tract of the healthy population was 0.94% (95%CI: 0.07%-2.78%), the infection rate of Mg was 11.58% (95%CI: 8.57%-14.97%), 15.22% (95%CI: 7.99%-24.27%), 7.32% (95%CI: 4.24%-11.16%) among patients from clinics or hospitals of STD, gynecology and urology respectively. The infection rate of MSM was 9.70% (95%CI: 3.06%-19.52%),the infection rate of FSW was 13.49% (95%CI: 11.97%-15.08%). The infection rate of Mg among HIV infected patients was 20.46% (95%CI: 13.67%-28.22%). Conclusions: The infection rate of Mg in a healthy population was low. Mg infection rate in the genitourinary tract of other groups was still higher, which is worthy of further attention.

Health Care Seeking Behavior in a Scheduled Tribe Community in India: A Mixed Methods Research Using the Framework of Andersen's Behavioral Model.

India's scheduled tribe population very often bears the brunt of inequity in accessing health care. The mixed-method research assessed the health care seeking behavior (HSB) of a tribal community residing in the eastern fringes of Kolkata metropolis. An adult, preferably the head, in 209 households was interviewed followed by qualitative interviews with relevant stakeholders. Conceptual framework of Andersen's behavioral model helped in identifying the potential predisposing, enabling, and need factors that influenced HSB. A total of 25.4% respondents reportedly sought informal care during last illness episode. Multivariable hierarchical-regression model (Nagelkerke R2 = 0.381) showed that respondents' education level [adjusted odds ratio (AOR) = 2.52], household size (AOR = 3.14), nonenrollment to health insurance (AOR = 2.47), decision making by household head (AOR = 2.40), distance from the nearest urban primary health center (AOR = 3.18), and poor perception to illness severity (AOR = 2.24) were significantly associated to inappropriate HSB. Predominant health system barriers that emerged from qualitative interviews were irregular logistics, unfavorable outpatient timing, absence of female doctors, and nonretention of doctors at local urban primary health center. Community level barriers were poor awareness, self-medication practices, poor health insurance coverage, and poor public transportation. Recognition of these determinants may help in developing health promotion interventions tailored to their needs.

Oral health-seeking behavior among different population groups in Enugu Nigeria.

INTRODUCTION: This study investigates the oral health-seeking behaviour of households and its influence on demand for dental caries treatment services in Enugu state Nigeria. METHODS: A quantitative descriptive cross-sectional study was used to explore the oral health seeking pattern of 378 urban and 348 rural household respondents in Enugu state Nigeria. The study explored dental caries treatment-seeking, oral health behavior of respondents using the three dynamics of the Andersen and Newman health utilization model; predisposing, enabling and need factors. FINDINGS: Recommendations from community members (48.9%), severity of disease (22.1%), and cost of treatment (19.4%) all influenced where oral healthcare was first sought. Gender and type of occupation, influenced positive oral health-seeking behavior (p<0.05). The least poor socioeconomic status (SES) group, sought dental treatment in the private dental clinics, while the very poor and most poor SES groups used traditional healers, home treatment and patent medicine dealers more. Dental fillings and extractions were generally the most accessed treatment options for dental caries. The tendency for all the SES groups (especially the least poor), to choose tooth extraction more as a treatment option for dental caries was influenced by the oral health awareness level of respondents and the cost of dental fillings. (p<0.05). CONCLUSION: The findings suggest that interventions to create increased oral health awareness targeted at education on preventive strategies, appropriate time and place to seek oral health care and dental caries treatment, as well devising and implementing health financing options such as dental insurance would enable individuals to seek appropriate treatment for dental caries on time. In addition, it will reduce the proportion of people visiting unorthodox healthcare providers for their oral health problems or choosing cheaper but inappropriate treatment options.

Improving Diabetes Care in the British Columbia Southern Interior: Developing Community‒University Initiatives to Address Service Gaps.

OBJECTIVES: Diabetes rates in the British Columbia (BC) interior are rising more rapidly compared with the rest of Canada, whereas diabetes service provision is limited within this region. The purposes of this article were: 1) to identify characteristics of diabetes service delivery; and 2) to co-develop community‒university diabetes research projects to address service barriers and gaps in the BC southern interior across urban, rural and Indigenous populations. METHODS: A 3-step approach was used. In step 1, a web search was conducted to identify diabetes-related services. In step 2, 10 community members working or volunteering in diabetes organizations participated in semistructured telephone interviews pertaining to diabetes service access, priorities, barriers, benefits and gaps. In step 3, a meeting of researchers and community members (n=25) was held to foster collaboration and co-develop research projects. RESULTS: Seventy-eight urban, rural and Indigenous diabetes-related services were identified in the BC southern interior. Provision of care to those with new type 1 diabetes and gestational diabetes diagnoses was identified in the interviews as a key priority; the needs of these groups contribute to a deficiency of resources to deliver prediabetes programs. The meeting produced plans for 2 collaborative projects: (1) the development of a diabetes patient journey map, and (2) development of a diabetes service hub with navigators for patients. CONCLUSIONS: Together, community members and researchers have identified service gaps and formulated research projects to improve diabetes management for urban, rural and Indigenous peoples living in the BC southern interior.
