Knowledge, attitudes, and practices of gouty arthritis in the general population aged > 30

A knowledge of gouty arthritis could help in the primary prevention of the disease development and lead to an early diagnosis if it occurs. This study investigated the knowledge, attitudes, and practices (KAP) toward gouty arthritis in the general population > 30 years old.

This web-based cross-sectional study was conducted among the general population > 30 years old between January and March 2023 in Chengdu, Sichuan. The questionnaire was designed by the investigators based on the available guidelines (Cronbach's α = 0.846). A score above 70% indicated good knowledge, a positive attitude, and proactive practice. Multivariable and structural equation modeling (SEM) analyses were performed to analyze the factors influencing KAP.

A total of 537 questionnaires were included. The knowledge, attitudes, and practices scores were 13.12 ± 6.41, 25.28 ± 3.97, and 45.25 ± 5.77, respectively. Female (OR = 0.47, 95%CI: 0.31-0.71, P < 0.001), suburban living (OR = 0.18, 95%CI: 0.04-0.78, P = 0.022), heads of institution/organization and professional and technical staff (OR = 2.04, 95%CI: 1.23-3.39, P = 0.006), and an income of < 2,000 yuan (OR = 0.35, 95%CI: 0.14-0.85, P = 0.021) were independently associated with knowledge. Female (OR = 2.17, 95%CI: 1.43-3.30, P < 0.001), age (OR = 1.03, 95%CI: 1.01-1.05, P = 0.001), college and above education (OR = 2.26, 95%CI: 1.16-4.41, P = 0.017), an income of 5,000-10,000 yuan (OR = 2.05, 95%CI: 1.27-3.31, P = 0.003), and an income of > 10,000 yuan (OR = 2.07, 95%CI: 1.12-3.81, P = 0.020) were independently associated with attitudes. Attitude (OR = 1.31, 95%CI: 1.23-1.40, P < 0.001), female (OR = 1.62, 95%CI: 1.01-2.58, P = 0.044), and age (OR = 1.02, 95%CI: 1.00-1.04, P = 0.016) were independently associated with practices. The structural equation modeling analysis showed that knowledge directly influenced attitude (β=-0.10, P < 0.001) and indirectly influenced practice (β=-0.07, P < 0.001), and attitude directly influenced practice (β = 0.68, P < 0.001).

The general population over 30 years old had inadequate knowledge, unfavorable attitudes, and less proactive practices toward gouty arthritis. Targeted interventions should focus on enhancing knowledge about gout and promoting positive attitudes toward its management.
