A two-tribe investigation has been carried out on & # 39; affecting western diet in blood pressure – ScienceDaily


The South American tribe resides in its remoteness as a whole and does not. affecting Western infection showed that there was no increase in average blood pressure from age to 60, according to survey led by researchers at the Public Health School Johns Hopkins Bloomberg. In comparison, a near-grown-up tribe includes some food and salt. show higher blood pressure at the end of age.

In U.S. and in most other countries, blood pressure is rising by age, and, begin early in life. The results of this survey support the view that the western western societies of Scotland do not increase blood pressure by age as a natural part of its & getting older, but this may be due to a gradual impact of taking care of Western food and lifestyle.

The results appear on November 14th in the magazine Cardio-knowledge JAMASouth Westerly

"The idea that raising blood pressure as a result of getting older than a cartoon belief, but our results add to evidence that pressure to have an impact on today's food and an outward lifestyle being rising to bloody blood rather than getting older, "said Noel Mueller, PhD, MPH, professor of the epidemiology at Bloomberg School and a member of the Welch Center for Prevention, Epidemiology and Research Clinic.

For the survey, researchers took a blood pressure measure from 72 Yanomami from one to 60 years old, and they did not find any move to read higher or lower readings than the older partners. Researchers also found their blood content in 83 members of the nearby Yekwana tribe, which are more pronounced to the West's effects. including food – and here they find a clear move to increase the weight of height to age.

The Yanomami lives as hunter-gatherers and gardeners in a remote water forest region of northern Brazil and southern Venezuela. The diet is low in fat and salt and high in fruit and fiber. Audits of an adult Yanomami from the 1980s have shown that knowledgeable creatures and obesity are largely unconnected, and that their blood pressure is relatively low at average, unlikely to increase when at age.

The new study indicates that Yanomami's premium blood pressure is an early childhood start. This is the first one that's a & # 39; compares the Yanomami and a co-settled population throughout the area – the Yekwana – which has differentiated Western diet and the influence of other Western life.

The researchers, who investigated members of Yanomami towns in southern Venezuela, had a degree of blood pressure. Approximately 95 (mm Hg) sistolic over 63 diastolic. (In the US adult, the systolic is average 122 and diastolic 71.) The low figure among Yanomami is consistent with pre-examinations in the Yanomami adults, but the researchers measured close to the same blood loss Yanomami children too. Indeed, the data shows that the blood pressure in this population is still relatively low at age one at least 60, without increasing or decreasing movement.

Compared to the Yanomami, the Yekwana has been open to some Western life and diet, including food handling, through interaction and trade with the industrial world . Although younger age-reader blood readings were broadly the same as those for their Yanomami contemporaries, there was a clear statistical shift in raising levels with age – approximately 0.25 mm Hg annually – therefore, levels at Yekwana level at 5.8 mm Hg were higher than 10, and 15.9 mm Hg were at the age of 50.

"This increase in blood is related to the age of early childhood – which suggests that early childhood may be a chance window & # 39; for lifestyle interventions to prevent further enhancement in blood pressure, "said Mueller.

In order to put these results into context, there will be a weight of about 1.5 mm Hg and 1.9 mm Hg in systolic blood pressure U.S. Each year, among boys and girls, and 0.6 mm Hg annually among adults.

Mueller and his colleagues are planning to go ahead with a review of the Yanutami and Yekwana gut bacteria; Determining whether the microbiome droplets describes the differences of the two tuberculosis in blood pressure by improving age.
