So as to facilitate the dietary assessment, we developed and assessed the validity and reproducibility of two food group-based meals frequency questionnaires (FG-FFQs), using a one-week (7-day FG-FFQ) as well as a one-month (30-day FG-FFQ) period of coverage for sufferers with pre-hypertension or hypertension. In 2010, 155 guys and women, 300 years old, have been invited to participate in a potential study in two outpatient clinics in Porto Alegre, southern Brazil. The participants responded to two 30-day, two 7-day FG-FFQ, 4 24-h dietary recalls, and underwent demographic, anthropometric, and blood stress assessments. The validity and reproducibility have been assessed using partial correlation coefficients adjusted for sex and age, and also the internal validity was tested making use of the intra-class correlation coefficient. The participants were aged 61 (0) years and 60 were women. The validity correlation coefficient was greater than r = 0.80 within the 30-day FG-FFQ for complete bread (r = 0.81) as well as the 7-day FG-FFQ for diet/light/zero soda and industrialized juices (r = 0.84) in comparison for the 24-h dietary recalls. The global internal validity was = 0.59, but it enhanced to = 0.76 when 19 redundant food groups had been excluded. The reproducibility was larger than r = 0.80 for pasta, potatoes and manioc, bakery goods, sugar and cocoa, and beans for both versions. The 30-day had a slightly greater validity, each had fantastic internal validity, as well as the 7-day FG-FFQ had a larger reproducibility.

Introduction Hypertension is usually a danger factor for stroke and coronary heart illness, and also other cardiovascular and non-cardiovascular diseases are amongst its consequences [1,2]. The challenge of preventing high blood stress (BP) should really drive population-based and clinical care interventions [2].
