General Flashcards
hypertrophic obersity
obersity characteriszed by increase in fat cell size
fat cell weight in avg-weight ppl = .5 micrograms
with weight gain, increase to 1.0 micrograms
what happens after the cell reaches 1.0 micrograms
hyperplastic obesity is more likely, i.e. increase in the NUMBER of fat cells rather than only inceeases in size
avg weight person number of fat cells?
25-35 billion.
a person with BMI over or at 40, can have as many as 100-150 billion cells
BEST Treatment
B = biological, e = enivron, s = social/psych, t = timing present weight loss effort, and together with patient in considering all four factors will choos ehte best Treatment
given what you know about hypertrophic vs. hyperplastic, why do some patients fail to reach sttsitically average weight even with bariatric surgery?
patients with severe hyperplastic obesity can have as many as two to three times as many fat cells as the average person. thus even when nomral fat cell weight (0.5 micrograsm) is aheived the patient still possess an increased fat mass
can i assess for fat cell size and number directly
no, obviously not, but i can estimate based of a chart in the Wadden and Phelan chapter
plots the relationship between cell number (billions) and percetnage of ideal body weight
how much variation to our genes account for when it comes to our weight
20-40%, twin and family studies (some estimates as high as 70%); polygenic
in addition to body weight, _______ seems to be heritable too
fat distribution
since there’s no good way yet to test someones genetic predispostion to obesity, how can i estimate how much biology is playing a role?
asses age of onsent, family history, and weight loss history
what is the strongest predictor of adult obseity?
the combination of, childhood onset of obseity + family history of obseity
70-75% of kids with these risk factor go on to be obse as adults
childhood and adolescent onset ____) your risk of adlt obseity
doubles
having one obese parent ______ your risk of adult obseity
doubles
which is stronger predciotr? mom or dad?
maternal obserity seems to be a stronger predicotr
when getting a family weight history dont forget to assess:
parents, sibiliing, maternal and paternal grandparents
what does rapid weight gain after treatment suggest?
higher likelyhood of hyperplastic obesity, greater biologiocal influence, patient may not regain statitically average weight
