Abstract:Metabolic Disorders and Adiposity in a Rural population.The aim of this cross-sectional study was to verify the prevalence of overweight and central adiposity (CA) in a sample of 287 adult subjects that lived in a rural community of Minas Gerais State. Means lipids, lipoproteins, glucose and blood pressure levels were compared according adiposity categories using One-way ANOVA and Tukey tests. Prevalence of overweight was 24.8% (37.4% for female; 11.5% for male). CA was verified in 28.1% of the individuals (50… Show more
“…Nutritional transition process and lifestyle changes have been observed in populations of metropolitan areas in Brazil since the 1970 8 . This phenomena has also been observed in rural areas, where major demographic, socioeconomic and epidemiological changes, results from forced modernization in the field and biased and exclusive development has caused changes in lifestyle profile of rural populations 9 , which has lead to increased lipid, glucose and blood levels, overweight and obesity 10,11 .…”
This article aims to evaluate associations between anthropometric changes in five years with lipid and blood pressure levels in Brazilian rural population. This longitudinal study evaluated 387 individuals aged 18 to 75 residents of two rural communities. Demographic, lifestyle, anthropometric, biochemical and hemodynamic characteristics were assessed in 2004 and repeated in 2009. Multivariate linear regression was used. Positive change in BMI was associated with increased diastolic blood pressure (DBP) (β = 0.07; 95%CI: 0.03-0.11), low-density lipoprotein (LDL-C) (increase of 0.01% to 10%: β = 0.08; 95%CI: 0.02-0.14, more than 10% increase: β = 0.09; 95%CI: 0.01-0.16) and low density lipoprotein/high density lipoprotein cholesterol ratio (LDL-C/HDL-C) (increase of 0.01% to 10%: β = 0.15; 95%CI: 0.06-0.25, more than 10% increase: β = 0.14; 95%CI: 0.02-0.25). Our results showed no association between positive changes in WC and lipid levels increase, only with blood pressure levels increase (SBP: β = 0.06; CI95%:0.02-0.10; DBP: β = 0.09; CI95%: 0.04;0.13). Positive changes in BMI are independent predictors of increased lipid and blood pressure levels and positive changes in WC of increased blood pressure.

“…No entanto, quando são considerados apenas os resultados de homens residentes na área rural do Brasil e na rural do Nordeste, observam-se diminuições das razões (1,5 e 0,7, respectivamente). Outros trabalhos realizados com adultos residentes em áreas rurais do Brasil apontaram para taxas de excesso de peso e obesidade mais baixas nos homens não indígenas 25,28,29 .…”
Este estudo transversal visa a descrever a distribuição de excesso de peso e obesidade e sua associação com variáveis demográficas e socioeconômicas entre 794 adultos indígenas, de 19 a 59 anos, da etnia Xukuru do Ororubá, povo indígena cujas terras estão localizadas no Município de Pesqueira, agreste de Pernambuco, Brasil. A análise da associação entre as variáveis de desfecho, excesso de peso (IMC > 24,99kg/m2) e obesidade (> 29,99kg/m2) e as variáveis explicativas foi realizada utilizando-se regressão logística multinível. Entre as mulheres, 52,2% estavam com excesso de peso e 21% obesas. Para os homens, as prevalências foram de 44,1% e 7,5%, respectivamente. As variáveis sexo feminino e idade (> 30 anos) estiveram associadas à ocorrência de ambos os agravos. Status socioeconômico e interação sexo masculino e renda per capita elevada apresentaram associação com obesidade. Assim como observado em outras populações indígenas, os achados sugerem que os Xukuru estão atravessando um acelerado processo de transição nutricional.
“…This result is expected, as this age group is more affected by factors that promote these metabolic alterations. The natural aging process associated to life habits, such as poor nutritional habits and sedentary lifestyle collaborates to the development of alterations in body composition and the metabolism of lipids and carbohydrates 32 . In addition to the aforementioned mechanisms, it is evident that the presence of diseases and stress can influence the levels of these tests, which are frequent conditions in elderly individuals 33 .…”
Background: Androgenic obesity is associated with a higher risk of metabolic disorders, thus favoring the occurrence of cardiovascular diseases and other morbidities.
