The aim of this study was to investigate the long-term outcome of quality of life (QOL) in the lower-limb amputees 10 years after the 2008 Sichuan earthquake.
In the cross-sectional study, 66 lower-limb amputees were recruited. The prosthetics-related QOL was assessed using the Prosthetic Evaluation Questionnaire (PEQ) in terms of the scales of utility, appearance, sounds, residual limb health, perceived response, frustration, social burden, ambulation, and well-being. The score of each PEQ subscale was calculated and compared among the cohorts with different demographic characteristics.
The PEQ scores showed that the scales of sounds, residual limb health, and frustration were still low in the lower-limb amputees 10 years after the 2008 Sichuan earthquake. The comparison of PEQ scales among cohorts with different demographic characteristics indicated that the potential demographic risk factors, namely, age, marital status, educational level, living independence, and comorbidity, were associated with prosthesis-related QOL.
The prosthesis-related QOL of the lower-limb amputees 10 years after the 2008 Sichuan earthquake has been partly documented in this study. The potential demographic risk factors associated with QOL of amputees were also identified. These findings could enhance the understanding of prosthesis-related QOL of lower-limb amputees sustained in an earthquake and facilitate the optimization of post-disaster rehabilitation strategies.
There is a dearth of data on the iodine balance studies of Chinese population. In the present study, we aimed to explore the appropriate recommended nutrient intake (RNI) of iodine based on healthy Chinese women. A 4-week study was conducted in twenty-five Chinese euthyroid women. Uniform diets with different iodine contents were provided in two different periods, in which non-iodised salt was given in the first 3 weeks, followed by 1 week of iodised salt administration. The total iodine intake from diet, water and air as well as the total iodine excretion through urine, faeces and respiration were monitored and determined. The sweat iodine loss was also considered. Moreover, the regression curve model was established between the 24 h iodine intake and 24 h iodine excretion. The 24 h iodine intake in the two periods was 194·8 (sd 62·9) and 487·1 (sd 177·3) μg/d, respectively. The 24 h iodine excretion was 130·9 (sd 39·5) and 265·4 (sd 71·8) μg/d, respectively. Both 24 h iodine intake and 24 h iodine excretion of the two periods were significantly different (all P<0·05). The iodised salt contributed approximately 62·7 % of the total daily iodine intake. Moreover, 92·3 % (277/300) of samples were in positive balance, while twenty-three cases were in negative balance. Our data show that the estimated average requirement for iodine was 110·5 μg/d. Therefore, the RNI for iodine to non-pregnant, non-lactating Chinese women was 154·7 μg/d.
