RESUMO

BACKGROUND: Although the levels of demand for family planning satisfied (DFPS) have increased in many countries, cultural norms remain a significant barrier in low- and middle-income countries. In the context of multireligious African countries, our objective was to investigate intersectional inequalities in DFPS by modern or traditional contraceptives according to religion and women's empowerment. METHODS: Analyses were based on Demographic and Health Surveys carried out between 2010 and 2021 in African countries. Countries with at least 10% of Muslims and Christians were selected to analyse inequalities in family planning. The religious groups were characterised by wealth, area of residence, women's age and women's empowerment. The mean level of empowerment was estimated for each religious group, and multilevel Poisson regression was used to assess whether DFPS varied based on the level of women's empowerment among Muslims and Christians. RESULTS: Our study sample of 14 countries comprised 35% of Muslim and 61% of Christian women. Christians had higher levels of empowerment across all three domains compared with Muslims and women with no/other religion. DFPS was also higher among Christians (57%) than among Muslims (36%). Pooled analysis indicated a consistent association between DFPS and women's empowerment, with higher prevalence ratios among Muslims than Christians, especially in the decision-making domain. CONCLUSIONS: The gap between Muslims and Christians in DFPS significantly reduced as the level of empowerment increased. It highlights the importance of understanding and addressing cultural factors sensibly and respectfully to satisfy the demand for family planning services.

RESUMO

BACKGROUND: Black adults are disproportionately affected by asthma and are often considered a homogeneous group in research studies despite cultural and ancestral differences. OBJECTIVE: We sought to determine if asthma morbidity differs across adults in Black ethnic subgroups. METHODS: Adults with moderate-severe asthma were recruited across the continental United States and Puerto Rico for the PREPARE (PeRson EmPowered Asthma RElief) trial. Using self-identifications, we categorized multiethnic Black (ME/B) participants (n = 226) as Black Latinx participants (n = 146) or Caribbean, continental African, or other Black participants (n = 80). African American (AA/B) participants (n = 518) were categorized as Black participants who identified their ethnicity as being American. Baseline characteristics and retrospective asthma morbidity measures (self-reported exacerbations requiring systemic corticosteroids [SCs], emergency department/urgent care [ED/UC] visits, hospitalizations) were compared across subgroups using multivariable regression. RESULTS: Compared with AA/B participants, ME/B participants were more likely to be younger, residing in the US Northeast, and Spanish speaking and to have lower body mass index, health literacy, and <1 comorbidity, but higher blood eosinophil counts. In a multivariable analysis, ME/B participants were significantly more likely to have ED/UC visits (incidence rate ratio [IRR] = 1.34, 95% CI = 1.04-1.72) and SC use (IRR = 1.27, 95% CI = 1.00-1.62) for asthma than AA/B participants. Of the ME/B subgroups, Puerto Rican Black Latinx participants (n = 120) were significantly more likely to have ED/UC visits (IRR = 1.64, 95% CI = 1.22-2.21) and SC use for asthma (IRR = 1.43, 95% CI = 1.06-1.92) than AA/B participants. There were no significant differences in hospitalizations for asthma among subgroups. CONCLUSIONS: ME/B adults, specifically Puerto Rican Black Latinx adults, have higher risk of ED/UC visits and SC use for asthma than other Black subgroups.

RESUMO

OBJECTIVES: We investigated access to dental services and associated factors in a community of Quilombola older people. BACKGROUND: Quilombola populations are groups of individuals descended from black Africans subjected to slavery during part of Brazilian history. As marginalised and neglected individuals, they have high rates of negative indicators and require further attention to the social determinants that affect their health reality. MATERIALS AND METHODS: A cross-sectional quantitative study was conducted in the Quilombola community of Castainho, in the Northeast region of Brazil. In this community, 34 older people aged between 65 and 74 resided. We collected self-report data on sociodemographic and economic characteristics, along with oral examinations by the researchers. The primary dependent variable was regular access to dental services. Statistical analysis used Fisher's exact test (P = .05). RESULTS: Among the 32 participants in the final sample, 18.8% (n = 6) reported accessing dental services in the previous 6 months. Self-declared individuals of mixed race, with positive self-assessment of oral health, and those who did not self-perceive the need for treatment had lower rates of regular access to dental services (P < .05). CONCLUSION: Use of dental services by older Quilombola people is low, and there are differences by ethnicity and individual perception of oral health.

RESUMO

The Mexico City Prospective Study is a prospective cohort of more than 150,000 adults recruited two decades ago from the urban districts of Coyoacán and Iztapalapa in Mexico City1. Here we generated genotype and exome-sequencing data for all individuals and whole-genome sequencing data for 9,950 selected individuals. We describe high levels of relatedness and substantial heterogeneity in ancestry composition across individuals. Most sequenced individuals had admixed Indigenous American, European and African ancestry, with extensive admixture from Indigenous populations in central, southern and southeastern Mexico. Indigenous Mexican segments of the genome had lower levels of coding variation but an excess of homozygous loss-of-function variants compared with segments of African and European origin. We estimated ancestry-specific allele frequencies at 142 million genomic variants, with an effective sample size of 91,856 for Indigenous Mexican ancestry at exome variants, all available through a public browser. Using whole-genome sequencing, we developed an imputation reference panel that outperforms existing panels at common variants in individuals with high proportions of central, southern and southeastern Indigenous Mexican ancestry. Our work illustrates the value of genetic studies in diverse populations and provides foundational imputation and allele frequency resources for future genetic studies in Mexico and in the United States, where the Hispanic/Latino population is predominantly of Mexican descent.

RESUMO

This article discusses the origin of quijila/kijila in Central West African culture, more particularly in the cultural universe of the Imbangala (Jaga) and the Ambundu and Kimbundu populations who lived in the Portuguese regions of Angola and the Congo in the seventeenth and eighteenth centuries. Following this, it investigates how the concept of quijila was structured, comprehended, and transformed, both in Africa, where it was basically a food prohibition, but whose applications and meanings varied; and in Brazil, to where it was transported in the 1700s, and where it transformed into a disease which attacked blacks, especially Africans of various origins, being framed as such in the Hippocratic-Galen universe characteristic of that time.


Este artigo discute a origem da quijila/kijila na cultura centro-ocidental africana, mais particularmente no universo cultural dos imbangalas (jagas) e das populações ambundos e kimbundos, que viviam nas regiões portuguesas de Angola e do Congo, nos séculos XVII e XVIII. Em seguida, investiga como foi estruturado, compreendido e transformado o conceito de quijila tanto na África, basicamente um interdito alimentar, mas cujos significados e aplicações variam, quanto no Brasil, para onde foi transportado nos Setecentos, transformando-se numa doença que atacava os negros, especialmente os africanos de diversas origens, sendo enquadrada pelos médicos locais no universo da medicina hipocrática-galena vigente na época.

RESUMO

The purpose of this work was to elaborate a diagnosis of the dissolution test in Africa in comparison with Brazil, evaluating the dissolution profile of low solubility drugs such as albendazole, ibuprofen, furosemide, glibenclamide, hydrochlorothiazide and carvedilol to ascertain their quality. The dissolution profiles were evaluated by utilizing the United States Pharmacopeia (USP). The glibenclamide medicine was evaluated according to the Food and Drug Administration (FDA), while a dissolution method was developed for the carvedilol medicine. A filter selection test for all the drugs showed that cannula is suitable for all, except for carvedilol, which is centrifuged. The various brands of Nigerian and Brazilian medicines tested showed some statistical differences. The suitable conditions that allowed the dissolution of carvedilol to be determined were the USP type II apparatus at 75 rpm containing 900 mL of acetate buffer, pH 4.5. The results of the dissolution test showed that out of the 17 different brands of Brazilian medicines and 17 different products from Nigeria, 94.12% and 58.82% passed respectively

RESUMO

The genetic background of Brazilians encompasses Amerindian, African, and European components as a result of the colonization of an already Amerindian inhabited region by Europeans, associated to a massive influx of Africans. Other migratory flows introduced into the Brazilian population genetic components from Asia and the Middle East. Currently, Brazil has a highly admixed population and, therefore, the study of genetic factors in the context of health or disease in Brazil is a challenging and remarkably interesting subject. This phenomenon is exemplified by the genetic variant CCR5Δ32, a 32 base-pair deletion in the CCR5 gene. CCR5Δ32 originated in Europe, but the time of origin as well as the selective pressures that allowed the maintenance of this variant and the establishment of its current frequencies in the different human populations is still a field of debates. Due to its origin, the CCR5Δ32 allele frequency is high in European-derived populations (~10%) and low in Asian and African native human populations. In Brazil, the CCR5Δ32 allele frequency is intermediate (4-6%) and varies on the Brazilian States, depending on the migratory history of each region. CCR5 is a protein that regulates the activity of several immune cells, also acting as the main HIV-1 co-receptor. The CCR5 expression is influenced by CCR5Δ32 genotypes. No CCR5 expression is observed in CCR5Δ32 homozygous individuals. Thus, the CCR5Δ32 has particular effects on different diseases. At the population level, the effect that CCR5Δ32 has on European populations may be different than that observed in highly admixed populations. Besides less evident due to its low frequency in admixed groups, the effect of the CCR5Δ32 variant may be affected by other genetic traits. Understanding the effects of CCR5Δ32 on Brazilians is essential to predict the potential use of pharmacological CCR5 modulators in Brazil. Therefore, this study reviews the impacts of the CCR5Δ32 on the Brazilian population, considering infectious diseases, inflammatory conditions, and cancer. Finally, this article provides a general discussion concerning the impacts of a European-derived variant, the CCR5Δ32, on a highly admixed population.

RESUMO

OBJECTIVES: Ageism has increased over 200 years and costs the U.S. health care system $63 billion a year. While scholars agree on the consequences of ageism, there are disagreements on whether it is related to the demographics of aging, or society's cultural values. We test both hypotheses across 20 countries. METHOD: To circumvent the sampling limitations of survey studies, we used an 8-billion-word corpus, identified 3 synonyms with the highest prevalence-aged, elderly, old people-and compiled the top 300 words (collocates) that were used most frequently with these synonyms for each of the 20 countries. The resulting 6,000 collocates were rated on an ageism scale by 2 raters to create an ageism score per country. Cultural dimension scores-Power Distance, Individualism, Masculinity, Uncertainty Avoidance, and Long-term Orientation-were taken from Hofstede, and demographics-size and speed of population aging-came from the World Development Indicators. RESULTS: Of the 20 countries, UK topped the ageism table, while Sri Lanka had the lowest ageism score. Multiple regression models showed that higher levels of masculinity and long-term orientation are associated with ageism, controlling for other cultural dimensions, demographics (size and speed of aging), and economics (GDP-per-capita). DISCUSSION: Our findings blunt the deterministic nature of ageism at the societal level. Demographics is only one side of the ageism coin, and the cultural side is equally, if not more important. This study lays the groundwork to tackle societal ageism-one of our generation's most pernicious threats.

RESUMO

The Mexican-Mestizo population arose following European contact with the Americas due to the admixture of principally Spaniards, Native Americans, and Africans around 500 years ago. Because the paternal lineage distribution of the Mexican population has been poorly investigated, this study inferred the haplogroups of ten populations based on 1859 haplotypes (Y-STR data) using two haplogroup predictor programs. In the Mexican population sample, we found predominantly European ancestry (50.1%), followed by Native American (32.5%), Eurasian (13.4%), African (2.1%), East African-South Eurasian (1.3%), and Asian (0.6%) ancestries. In general, our results support a contrary north-to-south gradient throughout the Mexican territory of European and Native-American ancestries, respectively. Moreover, the presence of West-European R1b and Sub-Saharan African E1b1a haplogroups agrees with historical and genetic data of gene flow during the European conquest. This study represents the effort to analyze these paternal lineages on a large scale by taking advantage of Y-STR haplotype data to determine the distribution and ancestry proportions in this country.
