Bariatric treatments for adult obesity - Institute of Health Economics

Results from Analysis of Provincial Health Utilization and CCHS dataTable E.6 shows the adjusted mean costs and visits from the six separate regression models. Whencombining physician and outpatient costs, the mean cost per obese resident in Alberta is $696. Thisis followed by costs of $545 for overweight, $523 for underweight, and $480 for normal weightresidents. Compared to normal weight, obesity, overweight, and underweight are associated withincreases of $217, $65, and $44, respectively.Based on information from the 2007 CCHS survey, for Alberta residents:463,000 were obese;843,000 were overweight; 58,000 were underweight.The economic burden of obesity in 2007 was estimated to be $100 million in Alberta when includingboth physician and outpatient services. This was followed by a cost for overweight of $55 millionand for underweight of $2.5 million. Furthermore, for obese individuals, the factors of femalegender, older age, lower income, lower education, no physical activity, and the presence ofcomorbidities were associated with increased economic burden (see Figure E.1). A similar pattern isobserved when analyzing health service visits (see Figure E.2.).Table E.6: Economic burden of obesity in 2007Mean cost/visit per resident by BMIBMIOutpatientandphysiciancostPhysiciancostOutpatientcostPhysicianvisitsOutpatientvisitsInpatientadmissionsUnderweight $523.24 $362.43 $192.35 7.272 0.705 0.066Normal weight $479.53 $315.77 $150.09 6.574 0.611 0.052Overweight $544.91 $372.93 $189.38 7.632 0.812 0.066Obese $696.44 $492.34 $245.68 9.877 1.130 0.081Incremental costs or visits compared to normal weightUnderweight $43.71 $46.65 $42.25 0.698 0.094 0.015Overweight $65.37 $57.16 $39.29 1.058 0.201 0.014Obese $216.90 $176.57 $95.58 3.303 0.519 0.029Economic burden of obesity (costs are in millions and visits are per 1000)Underweight versusnormal weightOverweight versusnormal weightObese versus normalweight$2.53 $2.70 $2.44 $0.33 5.45 0.85$55.10 $48.18 $33.11 $91.84 169.56 11.72$100.47 $81.79 $44.28 $530.24 240.44 13.61Bariatric treatments for adult obesity 172
