Surplus fat percentage review of the skinfold picture, bioimpedance and you may densitometry into the the elderly

Surplus fat percentage review of the skinfold picture, bioimpedance and you may densitometry into the the elderly

Extra fat estimate allows measuring alter through the years attributed to treatments and you may treatments in numerous setup including healthcare facilities, scientific routine, nursing homes and you may search. However, merely pair research has compared additional surplus fat estimation steps into the the elderly which have inconsistent overall performance. We projected excess fat commission (%BF) as well as the quantity of arrangement among twin time X-ray absorptiometry (DXA), bioelectrical impedance (BIA) and you may Durnin & Womersley’s skinfold eq. (SF) in older Brazilian adults old 60 ages and you will elderly on the More mature Venture Goiania, Brazil.


The new logical test made up of 132 users who’d DXA data. The degree of arrangement towards %BF estimated by BIA next, SF and DXA i.age. site strategy, was checked out playing with Terrifically boring and you can Altman’s and you may Lin’s area.

Overall performance

Overall, females got highest body mass index and you can %BF values mentioned from the all the around three procedures made use of. BIA and SF formula shown solid concordance so you can guess body fat fee in every players (CCC = 0.857 and 0.861, respectively) and you may certainly ladies (CCC = 0.788 and you may 0.726, respectively) when comparing to DXA. But not, both actions underestimated body fat fee in women and you will boys having highest extra fat fee. An effective level of agreement try noticed ranging from DXA and also the anthropometric formula created by Durnin & Womersley in men (CCC = 0.846), while BIA had a medium concordance (CCC = 0.505) contained in this class.


The new looked at steps conveyed other extra fat quotes. Although not, a knowledgeable arrangement is actually noticed anywhere between DXA and also the anthropometric SF equation for males. Upcoming research inside the the elderly would be to generate the SF equations given other cultural organizations.


New frequency from obesity has most enhanced global in the last partners ong the elderly . Being obese could have been regarding blood pressure levels, dyslipidemia, insulin resistance and diabetic issues mellitus, resulted in cardio illness instance cardiovascular system situation and you may ischemic coronary attack [2,step three,4]. The absolute most generally method accustomed measure the frequency of obesity position in society knowledge ‘s the body mass index (BMI) . Yet not, constraints and you can controversies concerning the the means to access Body mass index was indeed highlighted specifically due to its underestimation out of carrying excess fat frequency. Body constitution might have been felt a far greater alternative to Bmi inside the older adults due to many years-relevant increases from inside the excess fat fee (%BF) [5, 6]. High body fat is actually of this improved mortality and you will ineffective age . Ergo, %BF quote is very important into the epidemiological knowledge and also in health functions techniques instead of counting simply with the Bmi.

Skinfold (SF) proportions let the testing out of body structure because of the solid dating within quantity of subcutaneous fat and complete BF [nine, 10]. SF is actually a non-intrusive approach, an easy task to become mentioned possesses lowest performing costs . not, there can be nonetheless a need to take a look at SF equations’ reliability and you will agreement in order to anticipate %BF into the the elderly [eleven, 12].

The introduction of actions and/otherwise equations getting human anatomy constitution quote during the the elderly that will be taken for the populace studies if you’re bookkeeping into age-related alterations in muscles constitution stays a major difficulty [eleven, thirteen,fourteen,15]. Ageing impacts this new subcutaneous and you can visceral weight shipping. Thus, it’s important to use tips instance bioelectrical impedance (BIA) and you will dual-opportunity X-beam absorptiometry (DXA) to research the entire muscles. DXA ‘s the site fundamental means for human body structure estimation, particularly in the elderly, because individually procedures muscle tissue, fat and you may bone denseness which have each other an effective accuracy and you will accuracy [6, 16, 17]. However, its higher pricing and limited equipment access make this strategy unfeasible from inside the people degree and you can scientific setup.

Extra fat estimation is essential after in life [7, 8, eleven, sixteen, 18, 19]. They advances persistent conditions analysis and mortality risk analysis. At exactly the same time, extra fat estimate lets computing changes over time related to interventions and you can solutions in almost any options for example medical facilities, scientific practice, nursing facilities and you can research. However, only pair education [eleven, 20,21,22,23,24] has opposed some other surplus fat estimation procedures into the older adults with contradictory show. Thus, we aimed to test the fresh new arrangement away from BIA and you will SF picture which have DXA, since site means, to guess the newest BF fee inside older Brazilian adults.
