Specific health issues in ethnic minority groups

Prevalence of Self-Reported Chronic Diseases and Health Services Utilization by Ethnic Minorities in Manaus Metropolitan Region

Objectives

To assess the prevalence of, and associated factors to, self-reported chronic diseases and health care utilization by ethnicity in the Manaus Metropolitan Region.

Methods

We conducted a cross-sectional, population-based survey from May through August 2015. Using probabilistic sampling in three stages, we recruited adults aged ≥18 years. Ethnicity was self-identified as White, Black, Yellow, Brown (Brazilian mixed-race), and Indigenous. We calculated adjusted prevalence ratios (PR) and 95% CI of chronic diseases and health service utilization for each ethnic minority and compared the data using Poisson regression with data from White respondents.

Results

In this study, we interviewed 4,001 people. Of these, 15.9% were White, 7.5% Black, 3.4% Yellow, 72.1% Brown, and 1.0% Indigenous. Indigenous respondents had the highest prevalence of self-reported hypertension (29.4%), diabetes (12.3%) and hypercholesterolemia (17.0%) among the ethnic respondent groups. Compared with the White population, Browns had less health insurance coverage (PR=.76; 95% CI: .62-.93) and reported hypertension (PR=.84; 95% CI: .72-0.98) and diabetes (PR=.69; 95% CI: .51-.94) less frequently. Yellows visited the doctor more frequently than Whites (PR=1.13; 95% CI: 1.04-1.22), with no significant difference in prevalence of diseases.

Conclusions

Indigenous respondents had higher prevalence rates of the investigated diseases. Compared with Whites, Brown respondents had lower rates of self-reported arterial hypertension and diabetes, as well as lower rates of private health insurance coverage.

Tuberculosis in South Asian communities in the UK: a systematic review of the literature

BACKGROUND

Rates of tuberculosis (TB) in UK South Asian communities are up to 17 times higher than in white British groups. Latent infection in new migrants provides only a partial explanation. We undertook a systematic review of the literature to establish existing knowledge about TB in South Asian communities.

METHODS

We undertook a search for literature relating to TB and its management in South Asian communities in the UK. Articles initially identified were screened for relevance. A narrative review of relevant articles was then conducted.

RESULTS

We found 18 relevant articles. Associated risk factors for TB included poverty, deprivation, return visits to the Indian subcontinent, history of close contact with a case, gender, religion, possible dietary factors such as Vitamin D deficiency, duration of stay in the UK and country of birth. However, the evidence for these factors was often conflicting or weak, and suggests that commonly proposed hypotheses may not provide robust explanations for the higher rates of diagnosis.

CONCLUSIONS

Migration patterns and the demographic profile of the South Asian communities are constantly changing. Further research into the determinants of TB infection in these communities in the UK is urgently needed to inform the commissioning of TB health services.

Periodontal inflamed surface area and C-reactive protein as predictors of HbA1c: a study in Indonesia

Periodontitis may exert an infectious and inflammatory burden, evidenced by increased C-reactive protein (CRP). This burden may impair blood glucose control (HbA1c). The aim of our study was to analyze whether periodontitis severity as measured with the periodontal inflamed surface area (PISA) and CRP predict HbA1c levels in a group of healthy Indonesians and a group of Indonesians treated for type 2 diabetes mellitus (DM2). A full-mouth periodontal examination, including probing pocket depth, gingival recession, clinical attachment loss, plaque index and bleeding on probing, was performed in 132 healthy Indonesians and 101 Indonesians treated for DM2. Using these data, PISA was calculated. In addition, HbA1c and CRP were analyzed. A validated questionnaire was used to assess smoking, body mass index (BMI), education and medical conditions. In regression analyses, it was assessed whether periodontitis severity and CRP predict HbA1c, controlling for confounding and effect modification (i.e., age, sex, BMI, pack years, and education). In healthy Indonesians, PISA and CRP predicted HbA1c as did age, sex, and smoking. In Indonesians treated for DM2, PISA did not predict HbA1c. Periodontitis may impair blood glucose regulation in healthy Indonesians in conjunction with elevated CRP levels. The potential effect of periodontitis on glucose control in DM2 patients may be masked by DM2 treatment. Clinical relevance: periodontitis may impair blood glucose control through exerting an inflammatory and infectious burden evidenced by increased levels of CRP.

Cultural competence in health care and its implications for pharmacy. Part 1. Overview of key concepts in multicultural health care

Pharmacists are caring for more individuals of diverse age, gender, race, ethnicity, socioeconomic status, religion, sexual orientation, and health beliefs than in previous decades. Not all residents of the United States equally experience long life spans and good health. Health disparities in various cultures have been documented. One critical aspect of reducing health disparities is moving health care providers, staff, administrators, and practices toward increased cultural competence and proficiency. Effective delivery of culturally and linguistically appropriate service in cross-cultural settings is identified as cultural competence. Culture is a dynamic process, with people moving in and out of various cultures throughout their lives. The failure to understand and respect individuals and their cultures could impede pharmaceutical care. Incongruent beliefs and expectations between the patient and pharmacist could lead to misunderstandings, confusion, and ultimately to drug misadventures. Models and frameworks have been developed that provide descriptions of the process by which individuals, practice settings, and organizations can become culturally competent and proficient. This article, the first in a five-part series, presents an overview of issues related to cultural competence in health care with an emphasis on the pharmacy profession. Also provided are definitions for cultural competence and related terms, a brief overview of health disparities and challenges to the common morality, and a discussion of models and frameworks that describe pathways to cultural competence and proficiency.

Health worker style and trustworthiness as perceived by Pakistani-born persons with type 2 diabetes in Oslo, Norway

This article explores Pakistani-born persons' expectations regarding health encounters and health-worker style, and consequences for communication. It is part of a larger qualitative study involving both health workers and Pakistani-born persons in Oslo. An earlier publication based on interviews with health workers revealed dilemmas around role enactment, and described how they perceived Pakistani-born patients to expect an authoritarian health-worker style. The present article is based on interviews with patients and reveals that Pakistani-born diabetics expect empathy and care rather than an authoritarian style. The interviews indicate that lack of trust and diverging role expectations may be understood in the context of class and level of education, as well as ethnicity. Responding to theories about empowerment work and the dual impact of ethnicity and class, the study indicates that health workers should admit their professional expert role, and combine this role with a caring attitude in order to build trust.

Inflammation, obesity and cardiovascular function in African and Caucasian women from South Africa: the POWIRS study

The integrated relationship between inflammation, obesity and cardiovascular disease is currently a subject of much research interest. These specific relationships, however, have not been studied in-depth in South African population groups in order to determine the role of ethnicity. It is known that Africans, compared to Caucasians, suffer from a high prevalence of hypertension. It was therefore hypothesized that the levels of inflammatory markers (high-sensitivity C-reactive protein (hsCRP), fibrinogen and leptin) are higher in Africans compared to Caucasians and are notably associated with cardiovascular dysfunction in Africans. Apparently healthy African (N=102) and Caucasian (N=115) women, matched for age and body mass index (BMI), were recruited. Leptin, hsCRP, fibrinogen and lipid levels, waist circumference (WC), BMI, systolic and diastolic blood pressure, cardiac output (CO), total peripheral resistance (TPR) and Windkessel compliance were measured. Results showed that the levels of leptin, hsCRP and fibrinogen were significantly higher (P<0.05) in the African women. The inflammatory markers correlated strongly with cardiovascular parameters, age and obesity (BMI, WC) in both groups, but after adjusting for age and obesity, none of the correlations were significant anymore. Multiple regression analyses (with leptin, hsCRP or fibrinogen as dependent variable) showed that only leptin levels of African women were explained by cardiovascular parameters (BP, TPR and CO). In conclusion, even though African women had significantly higher leptin, hsCRP, fibrinogen and blood pressure levels than Caucasian women, no cardiovascular parameters explained the variation in the inflammatory markers (except for leptin levels of African women).
