title: Prevalence of hypertension in indigenous inhabitants of traditional communities from the north of Mexico.
abstract: The purpose of this study was to estimate the prevalence and risk factors of hypertension in adults indigenous to their traditional communities from the north of Mexico. The study was based on a cross- sectional survey of inhabitants from Mexicaneros, Huicholes and Tepehuanos communities, which have not been influenced by a western lifestyle. A home interview and clinical examination that included blood pressure and anthropometric measurements of 217 men and 598 non-pregnant women aged between 35 to 64 years was carried out. Eligible indigenous subjects must have had no migratory history to partially or totally urbanised areas. Target population represented approximately 100% of the indigenous people who have spent all their life time in the community of birthplace. Age and body mass index average was 48.9+/-12.9 years and 25.6+/-5.1 kg/m2. Hypertension was identified in 56 individuals, 45 women and 11 men (prevalence 6.87%, 95% confidence interval (CI) 5.1-8.6). Forty-one percent of the hypertensive subjects were aware of being hypertensive. Hypertensive subjects had a higher intake of saturated fats than non-hypertensives. Salt consumption was lower than 6 g per day in subjects with and without hypertension. High intake of saturated fats (odds ratio 6.4, 95% CI 2.1-12.3; P<0.01) was an independent predictor for hypertension. This study presents, for the first time, data concerning hypertension in adults who are indigenous to and living in traditional communities from Mexico. Prevalence of hypertension was lower than in the partly urbanised rural communities with a westernised lifestyle and the urban areas of Mexico.
