The study out of surface ranging from reported and yourself measured opinions inside 2008-2009 were according to the properties one, in all of the evaluations, the prices displayed represent a hateful estimate of the Brazilian people regarding the county capitals and you can places.
Brand new top and you may weight setting was in fact stratified seasons on 12 months out-of 20 in order to 29 yrs . old and you may biennia ranging from 31 and you may 39 years of age to maintain the fresh homogeneity of the test.
The fresh new VIGITEL and you can POF height and you will weight setting was basically compared statistically for each ages which have philosophy efficiently mentioned making use of the student’s t-sample. The brand new p viewpoints
To display the result of the stated and you may directly mentioned specifications, the costs having height, lbs and the entire body Mass List were log-switched plus the differences rather than the newest means plotted, due to the fact advised from the Humdrum & Altman. 2
Variations in beliefs getting level ranging from POF and you will VIGITEL displayed no scientific services for the people and you may just weren’t in the ages. Differences in beliefs getting lbs weren’t with the many years and you will the difference between means was not statistically high any kind of time age. There is no link between the differences in indicate pounds and you can the difference inside the mean height, i.age., whenever suggest weight is actually high inside the VIGITEL, imply top failed to realize people development to be large otherwise straight down (Dining table step 1).
Ten of the fifteen difference between level philosophy was mathematically high for females. The latest indicate level into the VIGITEL is actually more than one to for the POF inside the eight instances. For the ten evaluations, VIGITEL thinking exceeded those of POF getting pounds along with all of the of comparisons of over 30s. The values to own height had been large from inside the VIGITEL when you look at the nearly all of one’s reviews. The new VIGITEL opinions surpassed mean thinking about POF on the most of evaluations from lbs opinions (Table step 1).
The brand new structure between projected anthropometric indications considering specifications (POF) as well as on stated opinions (VIGITEL) throughout the Brazilian inhabitants during the 2008-2009 try assessed playing with Pearson (r) and Lin ( ? ) estimators predicated on sex and you may age group
Stratification of your own contrasting by the decades suggests, yet not, a lot fewer similarities between them surveys, especially in the fresh category of females just like the skinny otherwise over weight.
The VIGITEL viewpoints was greater than those individuals projected throughout the POF for similar age groups during the men. In women, the term away from large philosophy regarding the carrying excess fat quotes varied between 20 and 31 years of age and you may had a tendency to become higher inside the VIGITEL using this years and up (Profile step one).
Body mass index based on stated top and lbs opinions showed higher concordance ( ? ) and you will relationship (r) with that computed off actually measured beliefs for both sexes (Table 2)
The new dispersion out-of distinctions proportional on indicate among them surveys is higher among females than just boys, significantly getting weight beliefs. For women, the fresh new height and you may lbs thinking when you look at the VIGITEL exceeded the individuals noticed in new POF by on average doing 5%. For men, this new trend to possess VIGITEL opinions so you can meet or exceed POF opinions nevertheless existed, even in the event when you look at the magnitudes 
the new proportional differences of which were near to zero (Shape dos).
Investigations ranging from stated and you may in person measured level and you may pounds values in the fresh new Brazilian society of the county capitals and Government Region inside the 2008-2009 suggests: a) peak and you may weight opinions claimed of the interviewee were higher than those individuals individually mentioned in identical inhabitants; b) the male is smaller imprecise and you may inexact than just girls when bringing anthropometric data; c) total quotes according to Body mass index determined playing with reported otherwise counted beliefs try apparently close; d) there can be greater variability in the obesity rates whenever stratified because of the many years; e) the differences anywhere between mentioned and you may advertised opinions are more relevant to females. By the limiting the age diversity in the investigation, this research stopped the outcome are influenced by anthropometric action typical from progress completion during the adolescence and of age.
