Knowledge, Attitudes, and Reported Practices Regarding Prediabetes Among Hypertensive Patients With Abdominal Obesity: A Cross-Sectional Structural Equation Modeling Analysis
By Chen J, Cao X, Zhang J and 2 others.
Abstract
Background
We assessed prediabetes-related knowledge, attitudes, and reported practices among adults with hypertension and abdominal obesity and examined whether their associations were compatible with a hypothesized KAP structure.
Methods
This cross-sectional questionnaire survey included 446 adults recruited from April to June 2025. A revision-stage coding audit corrected P5 scoring. Because P4 and P6 had near-zero, nonsignificant loadings, the primary practice construct comprised P1, P2, P3, and P5; full-item models were retained as sensitivity analyses. Spearman correlations and structural equation modeling (SEM) were used.
Results
Mean knowledge, attitude, and four-item practice scores were 8.90 ± 2.14, 37.31 ± 3.68, and 10.75 ± 2.38. Correlations were 0.160 for knowledge-attitude, 0.173 for knowledge-practice, and 0.146 for attitude-practice (all p ≤ 0.002). The primary SEM showed acceptable fit (CMIN/DF = 2.127, RMSEA = 0.050, CFI = 0.925). Knowledge was associated with attitude (β = 0.160, p = 0.012), and attitude with practice (β = 0.281, p = 0.004); the direct knowledge-practice path was nonsignificant (β = 0.069, p = 0.402). The model-based indirect association was 0.045 (95% CI 0.016-0.091; p = 0.004). Practice showed weak convergent reliability (AVE = 0.199; CR = 0.464), and attitude responses had marked ceiling effects.
