Risk factors predicting hip pain in a 5-year prospective cohort study

by Tüchsen F, Hannerz H, Burr H, Lund T, Krause N

Objectives The aim of the study was to identify and quantify risk factors for hip pain.

Methods A representative sample of 5001 Danish men and women aged 18-65 years in 1990 were interviewed about occupational exposures (response rate 90%); 5 years later they were reinterviewed about hip pain (response rate 86%). Logistic regression with forced entry of all the independent variables was used to estimate the odds ratios for the possible risk factors. The impact of the various predictors was assessed through the calculation of population etiologic fractions.

Results A double risk of hip pain was found for the women as compared with the men [odds ratio (OR) 2.28, 95% confidence interval (95% CI) 1.68-3.09]. The risk increased with body mass index. Whole-body vibration (OR 1.86, 95% CI 1.09-2.71) and physically demanding work (OR 1.83, 95% CI 1.23-2.71) were strong predictors of hip pain, while a squatting work posture was protective (OR 0.64, 95% CI 0.42-0.98). The impact of the statistically significant predictors (the etiologic fractions) was as follows: 0.49 for body mass index, 0.05 for whole body vibration, 0.10 for physically demanding work, and 0.32 for squatting (preventive).

Conclusions Female gender, age, high body mass index, whole-body vibration, and physically demanding work are significant risk factors for hip pain.
