@sleepingdingo @raykellyfitness BMI (weight/height^2), is an imprecise measure of body composition (variability bw Pple /ethnic groups; we need sub cut fat, and we need muscle (but muscle weighs more than fat) and BMI can’t discern if weight is fat predominant or fat predominant. (Next)...
@sleepingdingo @raykellyfitness BMI is a size indicator of long term survival. But as a single measure might have limited prognostic survival indicator (next)...
@sleepingdingo @raykellyfitness previously, Regardless of adult age, normal range BMI was defined <25, &25-<30 as overweight (ie. lower survival with overweight)| now UN realises that healthy range BMI of older people needs refining to 24-30; because survival better associated with slightly higher BMI range.
@sleepingdingo @raykellyfitness But the take home message for all people, and older people, is preserve muscle, with resistance exercise and good nutrition, which has survival benefits; and for clinicians, to measure muscle mass (muscle is v important at rest and w exercise- antidiabetic and anti inflammatory
@sleepingdingo @raykellyfitness I tweeted this because I did my PHD in body composition of Aboriginal and Torres Strait Islander people across range of healthy- low kidney function
@sleepingdingo @raykellyfitness Our #eGFRstudy research, we showed a specific bioimpedance equation was accurate against DEXA FFM in Indigenous Australians- and this equation is different to populations where WHO develops its reference BMI measures
@sleepingdingo @raykellyfitness That was prob too much information... but population specific measures are so important; and I’m #proudtobeatorresstraitislander, and lead development of measures of interest which are specific and relevant to my community. Eso
@sleepingdingo @raykellyfitness What do my esteemed peers think on this? @raykellyfitness @SandroDemaio @synapse101 @Elif_Diabetes
