OBJECTIVE: This study aimed to estimate the direct healthcare costs associated with obesity in primary care and hospital settings in the adult population in Spain, and to describe the sociodemographic and clinical characteristics of individuals diagnosed with obesity.
METHODS: Observational, retrospective study using two unlinked nationwide public databases in Spain: the Primary Care Clinical Database (BDCAP) and the Specialized Care Activity Registry-Minimum Basic Data Set (RAE-CMBD), which collects data for hospitalizations. Adults aged ≥20 with obesity were identified based on diagnosis codes in medical records or discharge reports. Data included demographic and clinical characteristics, healthcare resource utilization, and characteristics of hospitalizations. Data for the year 2022 were analyzed independently for each database, using descriptive statistics.
RESULTS: Of 34,338,405 adults aged ≥20 identified in 2022 in the BDCAP, 10.3% had body mass index (BMI) records and, of these, 37.1% presented a BMI ≥30kg/m2. 3,285,946 (9.6%) had a diagnosis code for obesity. These had more visits to primary care in 2022 (22.2 versus 11.6), diagnostic or therapeutic procedures (20.5 versus 12.4 per person), or prescriptions for chronic medication than those without a diagnosis code. Annual cost in primary care for 2022 were €1656 per person diagnosed with obesity, versus €851 per person without a diagnosis. A total of 15,969 admissions to hospitals due to obesity were registered in the RAE-CMBD, with a cost of €79.8 million.
CONCLUSIONS: Obesity is under-recorded in public databases in Spain. Individuals diagnosed with obesity have higher estimated per-person costs than those without an obesity diagnosis.
