RESUMO

OBJECTIVE: to identify the risk factors associated with prehypertension and arterial hypertension among Munduruku indigenous people in the Brazilian Amazon. METHOD: a cross-sectional study carried out with 459 Munduruku indigenous people selected by means of stratified random sampling. Sociodemographic variables, habits and lifestyles, anthropometric data, fasting glucose and lipid profiles were evaluated. An automatic device calibrated and validated to measure blood pressure was used. The analyses of the data collected were carried out in the R software, version 3.5.1. For continuous variables, the Kruskall-Wallis test was used; for the categorical ones, Fischer's Exact. The significance level was set at 5% and p-value≤0.05. RESULTS: the prevalence of altered blood pressure levels was 10.2% for values suggestive of hypertension and 4.1% for pre-hypertension. The risk of prehypertension among indigenous people was associated with being male (OR=1.65; 95% CI=0.65-4.21) and having a substantially increased waist circumference (OR=7.82; 95% CI=1.80-34.04). Regarding the risk for arterial hypertension, it was associated with age (OR=1.09; 95% CI=1.06-1.12), with increased waist circumference (OR=3.89; 95% CI=1.43-10, 54) and with substantially increased waist circumference (OR=5.46; 95% CI=1.78-16.75). CONCLUSION: among Munduruku indigenous people, men were more vulnerable to developing hypertension; age and increased waist circumference proved to be strong cardiovascular risk factors.

RESUMO

OBJECTIVE: To evaluate the glycemic profile and its association with sociodemographic, anthropometric, clinical and lifestyle factors of Munduruku indigenous people. METHOD: Cross-sectional study with a quantitative and analytical approach, a total of 459 indigenous people (57.1% men, aged 36.3 ± 14.7 years old) belonging to the Munduruku ethnic group from the Kwatá-Laranjal Indigenous Land, in Amazonas, Brazil, were selected by probabilistic sampling in all households in the four most populous villages. Sociodemographic and anthropometric variables, blood pressure levels and lipid profile were evaluated. Fasting capillary blood glucose was measured with a digital device. The associations were assessed by multinomial logistic regression, and p-values≤0.05 were considered significant. RESULTS: For pre-diabetes, prevalence was 74.3% and, for diabetes, 12.2%. The variables associated with the risk for pre-diabetes were the following: age (OR = 1.03; 95% CI = 1.00 - 1.06) and obesity (OR = 9.69; 95% CI = 1.28 - 73.58). The positive associations indicating risk for diabetes were as follows: age (OR = 1.05; 95% CI = 1.03 - 1.08), overweight (OR = 4.17; 95% CI = 1.69 - 10.32) and obesity (OR = 35.26; 95% CI = 4.12 - 302.08). CONCLUSIONS: The risks associated with pre-diabetes and diabetes among the Munduruku indigenous people revealed a worrying index. It is necessary to consider changes in eating habits and lifestyle, as well as possible environmental and social changes that can affect this and other groups, with emphasis on those who live in vulnerable conditions.

Objetivo: identificar os fatores de risco associados à préhipertensão e hipertensão arterial entre indígenas Munduruku da Amazônia brasileira. Método: estudo transversal realizado com 459 indígenas Munduruku selecionados por meio de amostragem aleatória estratificada. Foram avaliadas variáveis sociodemográficas, hábitos e estilos de vida, dados antropométricos, glicemia de jejum e perfis lipídicos. Utilizou-se aparelho automático calibrado e validado para medir a pressão arterial. As análises dos dados coletados foram realizadas pelo software R versão 3.5.1. Para as variáveis contínuas, utilizou-se o teste Kruskall-Wallis; para as categóricas, o Exato de Fischer. Considerou-se nível de significância de 5% e valor p≤0,05. Resultados: a prevalência de níveis pressóricos alterados foi de 10,2% para valores sugestivos de hipertensão e de 4,1% para pré-hipertensão. O risco de pré-hipertensão entre indígenas associou-se a ser do sexo masculino (OR=1,65; IC95% 0,65-4,21) e ter circunferência da cintura aumentada substancialmente (OR=7,82; IC95% 1,80-34,04). Quanto ao risco para hipertensão arterial, associou-se à idade (OR=1,09; IC95% 1,06-1,12), à circunferência da cintura aumentada (OR=3,89; IC95% 1,43-10,54) e à circunferência da cintura aumentada substancialmente (OR=5,46; IC95% 1,78-16,75). Conclusão: entre indígenas Munduruku, os homens estavam mais vulneráveis para desenvolver hipertensão; a idade e a circunferência da cintura aumentada mostraram-se como fortes fatores de risco cardiovascular.
