What Is Obesity A life-long, progressive, life-threatening, costly, genetically related, multi-factorial disease of excess fat storage with multiple co-morbidities ASMBS.org

Malnutrition Any disorder of nutrition status including disorders resulting from a deficiency of nutrient intake, impaired nutrient metabolism or over nutrition Any disorder of nutrition status including disorders resulting from a deficiency of nutrient intake, impaired nutrient metabolism or over nutrition Therefore obesity is a form of malnutrition Therefore obesity is a form of malnutrition ASPEN – Board of Directors and Standards Committee

Malnutrition Historically, thought that micronutrient deficiencies were rare in Western countries because of the relatively low cost and ample food supply Historically, thought that micronutrient deficiencies were rare in Western countries because of the relatively low cost and ample food supply Many people consume food that is of poor nutritional quality however high in calories, fat, salt and/or sugar Many people consume food that is of poor nutritional quality however high in calories, fat, salt and/or sugar Kaidar-Person O, Person B, Szomstein S, Rosenthal RJ.

Measuring Obesity Measuring Obesity Determined by height and weight Determined by height and weight Body Mass Index (BMI) Body Mass Index (BMI) BMI = weight (kg)_____ height (m) x height (m) height (m) x height (m)

BMI Chart < 18.5 Underweight Healthy Weight Overweight Class I Obesity Class II Obesity >40.0Class III Obesity (Morbid Obesity)

BMI to Weight Examples A person 65” would have the following BMIs Weight (lbs)BMI (kg/m 2 ) Classification 10517Underweight 13022Healthy Wt 16527Overweight 19532Obesity I 23537Obesity II 26544Obesity III

Original Question If obesity is a form of malnutrition, what excesses or deficiencies should be evaluated, monitored and/or treated? If obesity is a form of malnutrition, what excesses or deficiencies should be evaluated, monitored and/or treated? Most research reporting micronutrient deficiencies in obese patients are the result of presurgical evaluations of bariatric patients Most research reporting micronutrient deficiencies in obese patients are the result of presurgical evaluations of bariatric patients

Study 1 Aim to assess concentrations of vitamins A, B1, B2, B6, folate, B12, C, D and E in morbidly obese patients compared to the concentrations in a healthy control group Aim to assess concentrations of vitamins A, B1, B2, B6, folate, B12, C, D and E in morbidly obese patients compared to the concentrations in a healthy control group Aasheim ET, Hofso D, Hjelmesaeth J, Birkeland KI, Bohmer T.

Discussion Having excess weight does not imply appropriate vitamin and trace mineral levels Having excess weight does not imply appropriate vitamin and trace mineral levels Poor nutrition habits of morbidly obese patients may make them more susceptible to lower levels of vitamins and minerals Poor nutrition habits of morbidly obese patients may make them more susceptible to lower levels of vitamins and minerals

Conclusions Consideration should be given to testing vitamin and trace minerals on any morbidly obese patients Consideration should be given to testing vitamin and trace minerals on any morbidly obese patients Other paper conclusions were specific to gastric bypass surgery Other paper conclusions were specific to gastric bypass surgery

Overall Conclusions When evaluated, obese patients presented with abnormal and deficient levels of several vitamin and trace minerals When evaluated, obese patients presented with abnormal and deficient levels of several vitamin and trace minerals
