Health-related quality of life and the ability to perform activities of daily living: a cross-sectional study on 1079 war veterans with ankle-foot disorders.

BACKGROUND

The ankle-foot injuries are among the war-related injuries that cause many serious secondary problems for a lifetime. This nationwide study aimed to assess health-related quality of life and the ability to perform activities of daily living in veterans with ankle-foot injuries due to the Iran-Iraq war.

METHODS

A total of 1079 veterans with ankle-foot injuries were enrolled in a cross-sectional study from 2014 to 2016. Demographic characteristics, including age, gender, marital status, disability percent, educational level, employment and additional injuries, were collected. The ability to perform daily activities was assessed using the Barthel activities of daily living (ADL) and Lawton instrumental activities of daily living (IADL) Indexes. Physical and mental health-related quality of life (HRQOL) data were measured via the SF-36 subscales. The data were compared with those of bilateral lower limb amputees (BLLAs) and of the general Iranian population. Statistical analyses, including Pearson's correlation coefficient, one-sample t-test and analysis of variance (ANOVA), were performed using SPSS16.0. A multiple linear regression model was used to determine the contribution of independent variables to the Physical Component Summary (PCS) and Mental Component Summary (MCS).

RESULTS

The highest and lowest scores were observed for mental health (48.93 ± 20.69) and bodily pain (28.16 ± 21.74), respectively. The mean scores of veterans with ankle-foot injuries on the SF-36 were significantly lower on all eight measures than those of the general Iranian male population and of the bilateral lower limb amputees (P < 0.001). The mean scores of ADLs and IADLs were 83.9 ± 16.3 and 5.3 ± 2.0, respectively. The higher dependency in ADLs (P < 0.001) and IADLs (P < 0.001), the higher disability rate (P < 0.001) and additional injury (P < 0.001) were significant determinants of the PCS. ADL (P < 0.001) and IADL (P < 0.001) limitations, additional injury (P < 0.001), history of hospitalization in the year preceding the study (P = 0.007) and employment (P = 0.001) were reported as determinants of the MCS.

CONCLUSION

The results strongly suggest that veterans with ankle-foot injuries suffer from critically poor health-related quality of life. The main predicting factors of HRQOL were the disability to perform ADLs/IADLs, suffering two or more injuries, a history of hospitalization in the year preceding the study and unemployment.
