Obesity rates on the rise in the US
The studies were carried out by Dr Marc Evans, University Hospital, Llandough, Penarth, Cardiff, UK, and Dr Jonathan Pearson-Stuttard at data and analytics firm Lane Clark & Peacock LLP, London, United Kingdom, and colleagues.
Obesity is known to cost health care approximately twice as much in the US as in people of a healthy weight.
The five studies spanned eight years and included 28,583 people living with obesity in the US. The authors concluded that: “Health care costs and hospital admissions are higher for taller individuals than for lower obesity. Our results emphasize the relationship between mass index and mass index.” body mass index (BMI) and increased utilization of health care resources and suggests that the progression of obesity can significantly contribute to the economic burden of the disease.”
Obesity rates and health care
Adults (18 years of age and older) were identified in the IQVIA Emergency Electronic Medical Record database and linked to the IQVIA PharMetrics Plus Administrative Claims database, both of which are normally used for large-scale research purposes.
People with a BMI of 30–70 kg/m² in the baseline period (1 January 2007-31 March 2012), and with continuous enrollment in the database for at least 1 year before base year and subsequent 8 years (up to 2020) were included in the analysis; Those who were pregnant or had cancer at the start of the study were excluded. The index date is the date their BMI was measured.
Three cohorts were established based on obesity class (class I: BMI 30–
High cost cases are defined as 20% of cases with the highest total cost in year 8; the remaining cases are specified in the low cost category.
Obesity classes and their burdens
For the obese group I, 20% of individuals have the highest healthcare expenditures, accounting for 79% of total healthcare expenditures in this group; for those with type II obesity, the figure was 77%, and for the class III obese group, it was 74%.
“We found that at least three-quarters of all direct health care costs among people with obesity in US clinical practice come from 20 percent of individuals,” the authors said. Those in the high-cost obesity group were substantially more likely to have obesity-related complications than those in the low-cost group, indicating a clear association between obesity-related complications and economic burden. .”
Second analysis of the same study subjects estimated how many ORCs (obstructive sleep apnea, heart failure, urinary incontinence, osteoarthritis of the knee, type 2 diabetes, prediabetes, asthma) , psoriasis, gastroesophageal reflux disease, hypertension, dyslipidemia, musculoskeletal pain, atherosclerotic cardiovascular disease and chronic kidney disease/renal failure) are present in people living with obesity at the start of the study.
The authors found that of the 28,583 people with obesity, 12,686 (44%) had no ORC, 7,242 (25%) had one ORC, 4,180 (15%) had two ORCs, and 4,475 (16%) had three ORCs. above.
The more ORCs an individual has, the higher their health care costs at the start of the study; and average costs increased for all groups during the eight years of the study, showing deterioration of ORCs or development of additional ORCs in all categories.
In each year, the cost increases with the number of ORCs; The average annual cost per person was highest for individuals with three or more ORCs (year 0, 14,290 USD; 8, 20,078) and lowest for those without ORC at the index (year). 0, 1,626 USD; year 8, 7,015 USD). For patients with one ORC or two ORCs, the costs were $4,649 and $7,089 in year 0, and $9,296 and $11,738 in year 8, respectively.
