ENERGY-LEVEL AND SLEEP QUALITY FOLLOWING BONE-MARROW TRANSPLANTATION

While problems with sleep and energy level (ie fatigue) are commonly r eported during recovery from bone marrow transplantation (BMT), little in-depth information regarding these two problem areas in BMT patient s is available, Using both questionnaire and telephone interview metho ds, information regarding current sleep and energy level problems was obtained from 172 adult BMT survivors drawn from five different BMT tr eatment centers, Respondents were a mean of 43.5 months post-BMT at th e time of the initial assessment, Similar questionnaire data was obtai ned from 137 respondents (80%) at a follow-up assessment 18 months aft er the initial assessment, Results suggested that half to two-thirds o f disease-free BMT recipients experience problems with regard to curre nt energy level or sleep quality, While for the majority of patients t hese problems were rated as mild, 15-20% of BMT recipients showed mode rate to severe problems in these areas with corresponding decrements i n quality of life, Furthermore, both cross-sectional and longitudinal analyses suggested that problems in these areas did not simply abate w ith time, Only low to moderate correlations were obtained between indi ces of sleep and energy problems and measures of anxious and depressed mood, Finally, the presence of current sleep problems was associated with older age at BMT, receipt of TBI during pre-BMT conditioning, and female gender, Further research needs to address the specific etiolog y of chronic problems with sleep and energy level in BMT recipients as well as evaluate biobehavioral strategies for managing these problems .
