In this Mendelian randomization study in 32,439 adults (average age of 47), coffee intake was associated with an increased risk of developing osteoarthritis.

The study
The authors analyzed data from 10 rounds of the National Health and Nutrition Examination Survey (1999–2018). Participants who were diagnosed with osteoarthritis made up 11% of the sample. Coffee intake was assessed using 24-hour dietary recalls.
In the non-Mendelian randomized analysis, higher coffee intake (over 4 cups per day) was associated with 19% higher odds of osteoarthritis than no coffee intake. The analysis was adjusted for potential confounders, including demographics, health status, and lifestyle factors.
The Mendelian randomization analysis supported the observational results, suggesting increased odds of developing knee (+60%), hip (+80%), or knee and hip (+66%) osteoarthritis when accounting for gene variants that influence coffee intake.
