Exposure Levels

The Amazonian indigenous peoples depend on natural resources to live, but human activities’ growing impacts threaten their health and livelihoods. Our objectives were to present the principal results of an integrated and multidisciplinary analysis of the health parameters and assess the mercury (Hg) exposure levels in indigenous populations in the Brazilian Amazon. We carried out a cross-sectional study based on a census of three Munduruku indigenous villages (Sawré Muybu, Poxo Muybu, and Sawré Aboy), located in the Sawré Muybu Indigenous Land, between 29 October and 9 November 2019. The investigation included: (i) sociodemographic characterization of the participants; (ii) health assessment; (iii) genetic polymorphism analysis; (iv) hair mercury determination; and (v) fish mercury determination. We used the logistic regression model with conditional Prevalence Ratio (PR), with the respective 95% confidence intervals (CI95%) to explore factors associated with mercury exposure levels ≥6.0 µg/g. A total of 200 participants were interviewed. Mercury levels (197 hair samples) ranged from 1.4 to 23.9 μg/g, with significant differences between the villages (Kruskal–Wallis test: 19.9; p-value < 0.001). On average, the general prevalence of Hg exposure ≥ 6.0 µg/g was 57.9%. For participants ≥12 years old, the Hg exposure ≥6.0 µg/g showed associated with no regular income (PR: 1.3; CI95%: 1.0–1.8), high blood pressure (PR: 1.6; CI95%: 1.3–2.1) and was more prominent in Sawré Aboy village (PR: 1.8; CI95%: 1.3–2.3). For women of childbearing age, the Hg exposure ≥6.0 µg/g was associated with high blood pressure (PR: 1.9; CI95%: 1.2–2.3), with pregnancy (PR: 1.5; CI95%: 1.0–2.1) and was more prominent among residents in Poxo Muybu (PR: 1.9; CI95%: 1.0–3.4) and Sawré Aboy (PR: 2.5; CI95%: 1.4–4.4) villages. Our findings suggest that chronic mercury exposure causes harmful effects to the studied indigenous communities, especially considering vulnerable groups of the population, such as women of childbearing age. Lastly, we propose to stop the illegal mining in these areas and develop a risk management plan that aims to ensure the health, livelihoods, and human rights of the indigenous people from Amazon Basin.

Sinar ultraviolet B adalah sumber utama vitamin D, tetapi wanita usia subur yang bekerja di dalam ruangan mempunyai vitamin D yang rendah meskipun Indonesia negara tropis. Tujuan penelitian ini untuk mengevaluasi peranan paparan sinar matahari pada wanita usia subur terhadap status vitamin D dan tekanan darah. Desain penelitian yang digunakan adalah eksperimen tanpa kelompok kontrol pada 21 wanita sehat. Penelitian ini membandingkan status vitamin D dan tekanan darah sebelum dan setelah mendapat paparan sinar matahari pada wajah dan lengan tiga kali seminggu selama 12 minggu. Analisis data menggunakan uji t-berpasangan. Paparan sinar matahari dapat meningkatkan vitamin D. Serum 25(OH)D meningkat 15,9% dari 15.7 ng/dL menjadi 18,2 ng/dL. Paparan sinar matahari menurunkan tekanan darah sistolik (nilai p = 0,004) dan diastolik (nilai p = 0,011). Ultraviolet B dari sinar matahari 30 menit tiga kali seminggu selama 12 minggu dapat memperbaiki status vitamin D dan tekanan darah.Ultraviolet B sunlight exposure is a primary source of vitamin D, but women of childbearing age who worked in room every day had low serum vitamin D despite Indonesia is a tropical country. The objective of this study was to evaluate the role of sun exposure in women of childbearing age on vitamin D status, and blood pressure. An intervention before-after study without group control was conducted on 21 healthy women. This study compared vitamin D status, and blood pressure before and after receiving ultraviolet B (UVB) from sun exposure on the face and both arms three times a week for 12 weeks. Anthropometric parameter and blood pressure were measured, were determined at baseline and after 12 weeks of sun exposure. The effect of sun exposure can improve vitamin D. Serum 25 (OH)D increase 15.9% from 15.7 ng/dL to 18.2 ng/dL. Sun exposure significantly reduced systolic blood pressure (p value = 0.004), and diastolic blood pressure (p value = 0.011). Ultraviolet B from sun exposure for 30 minutes, 3 times a week for 12 weeks improves the vitamin D status, and blood pressure.

Abstract Hypertensive disorders are among the leading conditions for severe maternal morbidity across all regions and has a major impact on health care costs. The aim of this study was to determine the sociodemographic correlates of hypertension in Lesotho. Methods: For analysis, women of women of childbearing age (15–49 years) who have ever given birth in the five years preceding the 2014 LDHS. The dependent variable of this study is hypertension. Univariate and bivariate analyses were done. The correlation was tested using Pearson correlation coefficient while binary logistic regression are used to determine sociodemographic correlates of hypertension Results: Results from this study revealed that one out of every five respondents of the study had hypertension and 79.3 % of the respondents were in prehypertension stage. The situation adds to overall future risk of hypertension. About 20% percent who were at stage 2 of hypertension (SBP ≥ 160 (mmHg) or DBP SBP ≥ 100 (mmHg) were either living with a partner or widowed. Higher ages (45–49 years) of women was found to be significantly associated with high blood pressure levels. Conclusion: Chances of being diagnosed with high blood pressure increased with an increase with age of the respondents. Age was found to be most significant sociodemographic correlate of hypertension. To control hypertension programs should also focus on the psychosocial hypertension interventions for Basotho women in the higher risk groups.

Methylmercury Exposure

In line with the 1000-day initiative and the Sustainable Development Goals (SDG) 2 and 3, we present a cross-sectional analysis of maternal health, infant nutrition, and methylmercury exposure within hard-to-reach indigenous communities in the state of Pará, Brazilian Amazon. We collected data from all women of childbearing age (i.e., 12–49) and their infants under two years old in three Munduruku communities (Sawré Muybu, Sawré Aboy, and Poxo Muybu) along the Tapajos River. We explored health outcomes through interviews, vaccine coverage and clinical assessment, and determined baseline hair methylmercury (H-Hg) levels. Hemoglobin, infant growth (Anthropometric Z scores) and neurodevelopment tests results were collected. We found that 62% of women of childbearing age exceeded the reference limit of 6.0 μg/g H-Hg (median = 7.115, IQR = 4.678), with the worst affected community (Sawré Aboy) registering an average H-Hg concentration of 12.67 μg/g. Half of infants aged under 24 months presented with anemia. Three of 16 (18.8%) infants presented H-Hg levels above 6.0 µg/g (median: 3.88; IQR = 3.05). Four of the 16 infants were found to be stunted and 38% of women overweight, evidencing possible nutritional transition. No infant presented with appropriate vaccination coverage for their age. These communities presented with an estimated Infant Mortality Rate (IMR) of 86.7/1000 live births. The highest H-Hg level (19.6 µg/g) was recorded in an 11-month-old girl who was found to have gross motor delay and anemia. This already vulnerable indigenous Munduruku community presents with undernutrition and a high prevalence of chronic methylmercury exposure in women of childbearing age. This dual public health crisis in the context of wider health inequalities has the potential to compromise the development, health and survival of the developing fetus and infant in the first two critical years of life. We encourage culturally sensitive intervention and further research to focus efforts.
