AbstractBackgroundEthnic minorities have higher rates of SARS-CoV-2 diagnoses, but little is known about ethnic differences in past exposure. We aimed to determine whether prevalence and determinants of SARS-CoV-2 exposure varied between six ethnic groups in Amsterdam, the Netherlands.MethodsParticipants aged 25-79 years enrolled in a population-based prospective cohort were randomly selected within ethnic groups and invited to test for SARS-CoV-2-specific antibodies and answer COVID-19 related questions. We estimated prevalence and determinants of SARS-CoV-2 exposure within ethnic groups using survey-weighted logistic regression adjusting for age, sex and calendar time.ResultsBetween June 24-October 9, 2020, we included 2497 participants. Adjusted SARS-CoV-2 seroprevalence was comparable between ethnic-Dutch (25/498; 5.5%, 95%CI=3.2-7.9), South-Asian Surinamese (22/451; 4.8%, 95%CI=2.1-7.5), African Surinamese (22/400; 8.2%, 95%CI=3.0-13.4), Turkish (30/408; 7.8%, 95%CI=4.3-11.2) and Moroccan (32/391; 7.0%, 95%CI=4.0-9.9) participants, but higher among Ghanaians (95/327; 26.5%, 95%CI=18.7-34.4). 57.1% of SARS-CoV-2-positive participants did not suspect or were unsure of being infected, which was lowest in African Surinamese (18.2%) and highest in Ghanaians (90.5%). Determinants of SARS-CoV-2 exposure varied across ethnic groups, while the most common determinant was having a household member suspected of infection. In Ghanaians, seropositivity was associated with older age, larger household sizes, living with small children, leaving home to work and attending religious services.ConclusionsNo remarkable differences in SARS-CoV-2 seroprevalence were observed between the largest ethnic groups in Amsterdam after the first wave of infections. The higher infection seroprevalence observed among Ghanaians, which passed mostly unnoticed, warrants wider prevention efforts and opportunities for non-symptom-based testing.

ObjectivesIt has been suggested that ethnic minorities have been disproportionally affected by the COVID-19. We aimed to determine whether prevalence and correlates of past SARS-CoV-2 exposure varied between six ethnic groups in Amsterdam, the Netherlands.Design, setting, participantsParticipants aged 25–79 years enrolled in the Healthy Life in an Urban Setting population-based prospective cohort (n=16 889) were randomly selected within ethnic groups and invited to participate in a cross-sectional COVID-19 seroprevalence substudy.Outcome measuresWe tested participants for SARS-CoV-2-specific antibodies and collected information on SARS-CoV-2 exposures. We estimated prevalence and correlates of SARS-CoV-2 exposure within ethnic groups using survey-weighted logistic regression adjusting for age, sex and calendar time.ResultsBetween 24 June and 9 October 2020, we included 2497 participants. Adjusted SARS-CoV-2 seroprevalence was comparable between ethnic Dutch (24/498; 5.1%, 95% CI 2.8% to 7.4%), South-Asian Surinamese (22/451; 4.9%, 95% CI 2.2% to 7.7%), African Surinamese (22/400; 8.3%, 95% CI 3.1% to 13.6%), Turkish (30/408; 7.9%, 95% CI 4.4% to 11.4%) and Moroccan (32/391; 7.2%, 95% CI 4.2% to 10.1%) participants, but higher among Ghanaians (95/327; 26.3%, 95% CI 18.5% to 34.0%). 57.1% of SARS-CoV-2-positive participants did not suspect or were unsure of being infected, which was lowest in African Surinamese (18.2%) and highest in Ghanaians (90.5%). Correlates of SARS-CoV-2 exposure varied across ethnic groups, while the most common correlate was having a household member suspected of infection.

Different Genetic Background

Background: Craniofacial anthropometry is a technique used in both physical and clinical anthropology comprising precise and systematic measurements of the human skull. It also includes measurement of the medial and lateral canthal distances. People of different genetic background subjected to significantly different environmental influences have different craniofacial morphology.Objectives: To find out effect of gender and ethnicity on Canthal anthropometry.Methods: This descriptive cross-sectional study was carried out to determine and compare canthal anthropometry among 299 undergraduate students (Male=161, Female=138) of different ethnic groups (Indo-Nepalese, indigenous and Tibeto-Nepalese) of age group 19-21 years at BPKIHS. Medial and lateral canthal distances were measured by using straight vernier caliper and canthal index (medial canthal distances / lateral canthal distance × 100) for all three ethnic groups in both sexes were compared.Results: The study has shown that the female students had higher canthal index than male students (27.65±12.35 vs 23.96±5.76). When compared on the basis of ethnicity, Indo-Nepalese had highest value of canthal index followed by Indigenous and Tibeto-Nepalese.Conclusion: In conclusion, genetics and environmental factors are responsible for the variation in canthal indices and other craniofacial indices between and within populations. Therefore, its standard values are largely applicable for clinical assessment of patients with syndrome affecting canthal anatomy.DOI: http://dx.doi.org/10.3126/jkmc.v3i2.11231Journal of Kathmandu Medical CollegeVol. 3, No. 2, Issue 8, Apr.-Jun., 2014Page: 78-81

Objectives: To compare the prevalence of myasthenia gravis (MG) subgroups based on immunological markers and clinical presentation in two geographically complete MG populations in northern Europe. Methods: This cross-sectional study included all living MG patients in Norway and a regional cohort from the Netherlands. Patients were identified using their hospital registration codes. Medical charts of subjects >16 years were reviewed. Inclusion criteria were clinical MG, a positive antibody test for acetylcholine receptor (AChR MG) or muscle-specific kinase (MuSK MG), or if seronegative MG, confirmed by an electrophysiological test. Results: 1,205 MG patients (534 Norwegians and 671 Dutch) fulfilled the criteria, giving a higher point prevalence in the Netherlands (167/million, 95% CI 155-180) than in Norway (138/million, 95% CI 126-150). In particular, rates of AChR MG (143 vs. 111/million), MuSK MG (6.5 vs. 0.5/million), and ocular phenotype (62 vs. 24/million) were higher in the Netherlands. Conclusion: Novel findings are an AChR MG geographical north-south gradient and a 2.6-fold more ocular MG patients in the Netherlands than in Norway. The MuSK MG latitudinal gradient supports the notion of a north-south gradient in Europe, with a higher prevalence in the south. The variation is probably explained by genetic differences between the populations, in addition to environmental interactions.

Abstract AimTo assess the degree and determinants of COVID-19 Vaccine among NigeriansMaterials and methodsFollowing appropriate ethical protocol, a population-based cross-sectional study conducted from November 2020 to January 2021 using a pretested, self-administered questionnaire from a previous study adapted to suit the Nigeria setting and distributed among Nigerians aged 18 years and above. The country was grouped in to three regions: East, North and West representing the major ethnic groups in Nigeria. Participants were recruited based on six different catchments: residential, marketplace recreational areas, cooperate organizations, schools, and Faith-based organizations. Information obtained include socio-demographics, medical history related pertinent to COVID-19, level of knowledge, risk perception, and attitudes towards of COVID-19 and the vaccine amongst others. Descriptive and inferential statistics were done on the variables and results were summarized into percentages and associations noted.ResultsA total of 358 responses were obtained out of the 120 questionnaires distributed in each of the three regions of which. The mean age of respondents was 32years (± 11.2SD). Igbo and Yoruba were the major ethnic groups comprising 38% and 31% of study participants respectively. Three-quarter had tertiary education, 43% of them were civil servants and professionals, 34% of them were unemployed, and 8.9% of them were roadside traders. Majority (66.2%) were willing to accept the approved vaccine with male gender, identifying as Christian, Hausa ethnicity and living in the northern Nigeria had a significant positive association with COVID-19 vaccine uptake.Conclusiontwo out of three Nigerian adults indicated interest in accepting the corona virus vaccine. This calls with critical stakeholders and leaders at all levels to be involved in public education based on sound evidence and the discouragement of the spread of conspiracy theories to eliminate the negative associated factors will reduce vaccine hesitancy and increase COVID-19 vaccination rates in Nigeria.

Abstract Background Ethnic minority groups from Asia and Africa living in Western countries have a higher prevalence of type 2 diabetes (T2DM) than the general population. We aimed to assess ethnic differences in diabetes care by gender. Methods Population-based, cross-sectional study identified 10,161 individuals with T2DM cared for by 282 General Practitioners (GP) in Norway. Ethnicity was based on country of birth. Multilevel regression models adjusted for individual and GP factors were applied to evaluate ethnic differences by gender. Results Diabetes was diagnosed at a younger mean age in all other ethnic groups compared with Westerners (men: 45.9–51.6 years vs. 56.4 years, women: 44.9–53.8 years vs. 59.1 years). Among Westerners mean age at diagnosis was 2.7 years higher in women compared with men, while no gender difference in age at diagnosis was found in any minority group. Daily smoking was most common among Eastern European, South Asian and Middle East/North African men. In both genders, we found no ethnic differences in processes of care (GPs’ measurement of HbA1c, blood pressure, LDL-cholesterol, creatinine). The proportion who achieved the HbA1c treatment target was higher in Westerners (men: 62.3%; women: 66.1%), than in ethnic minorities (men 48.2%; women 53.5%). Compared with Western men, the odds ratio (OR) for achieving the target was 0.45 (95% CI 0.27 to 0.73) in Eastern European; 0.67 (0.51 to 0.87) in South Asian and 0.62 (0.43 to 0.88) in Middle Eastern/North African men. Compared with Western women, OR was 0.49 (0.28 to 0.87) in Eastern European and 0.64 (0.47 to 0.86) South Asian women. Compared with Westerners, the blood pressure target was more often achieved in South Asians and Middle Easterners/North Africans in both genders. Small ethnic differences in achieving the LDL-cholesterol treatment target by gender were found. Conclusion Diabetes was diagnosed at a considerably earlier age in both minority men and minority women compared with Westerners. Several minority groups had worse glycaemic control compared with Westerners in both genders, which implies that it is necessary to improve glucose lowering treatment for the minority groups. Smoking cessation advice should particularly be offered to men in most minority groups.
