NEW YORK, Nov. 11, 2014—More than half of adults in Brazil are overweight or obese, with 34 percent having body mass index (BMI) levels that classify them as overweight (BMI ≥ 25 kg/m2 and BMI < 30 kg/m2) and 18 percent having BMI levels that classify them as being obese (BMI ≥ 30 kg/m2), according to new findings from Kantar Health’s National Health and Wellness Survey (NHWS). The research will be presented today at the 17th Annual ISPOR (International Society for Pharmacoeconomics and Outcomes Research) European Congress in Amsterdam.
“Obesity is becoming a major national health concern in Brazil,” said Shaloo Gupta, Manager, Health Outcomes Research, Kantar Health. “The high prevalence of obesity is associated with an increase in comorbidities such as hypertension, dyslipidemia, arthritis and type 2 diabetes in Brazil, and it also places a large burden on the healthcare system and is costly for patients.”
Kantar Health’s research found that obese adults in Brazil had greater presenteeism, or impairment due to health status while at work, than adults who have normal BMI. Activity impairment also increased significantly as BMI increased. The increased work productivity loss translates into higher indirect costs, or expenses incurred from reduction of work productivity, for obese adults compared with normal weight adults (R$333 per year for employed adults with normal BMI versus R$385 for obese class I respondents, R$395 for obese class II respondents, and R$458 for obese class III respondents).
Likewise, adults in Brazil with normal BMI reported significantly fewer provider and ER visits compared with obese adults. In line with higher resource use, total direct costs due to provider visits, ER visits and hospitalizations increased as BMI increased. Direct costs for private healthcare are R$1,722 per year for adults with normal BMI, rising to R$2,453 for adults with class III obesity.
“Our research provides evidence that health professionals should be aware that obese patients with even a modest amount of weight loss would benefit from a quality-of-life perspective,” Gupta said.
About the National Health and Wellness Survey (NHWS)
The study’s results were drawn from the 2011 and 2012 Brazil NHWS, a nationally representative, self-administered survey conducted annually. Topics covered include the health status, attitudes, behaviors and outcomes among adults 18 or older.
Kantar Health conducts the NHWS in the U.S., Europe, Asia and Latin America. The survey is the largest self-reported dataset in the healthcare industry.
