Conclusion The prevalence of sarcopenia depends mostly on the diagnostic cut-off points of different criteria .
Preoperative sarcopenia is a risk factor for both long-term and short-term outcomes
Background The impact of sarcopenia on the outcome of gastrointestinal ( GI ) oncological patients is still controversial .
We aim to discuss the prevalence of sarcopenia and its relation to the oncological outcome .
Physical activity as a determinant of change in mobility performance: the Longitudinal Aging Study Amsterdam.
OBJECTIVES This study examined the association of ( change in ) physical activity and decline in mobility performance in older men and women . DESIGN A 3-year prospect i ve study using data of the Longitudinal Aging Study . SETTING Netherl and s. PARTICIPANTS Two thous and one hundred nine men and women aged 55 to 85 . MEASUREMENTS  Total physical activity  ( expressed as hours per day and kilocalories per day ) and sports participation  were measured using a vali date d , interviewer-administered question naire .  Mobility performance was assessed using two timed tests : 6-meter walk and repeated chair st and s. RESULTS Mobility performance declined for 45.6 % of the sample . At baseline , the mean time + /- st and ard deviation spent on total physical activity was 3.0 + /- 2.1 h/d or 719 + /- 543 kcal/d , and 56.6 % of the sample participated in sports . Sports participation and a higher level of total physical activity , walking , or household activity were associated with a smaller mobility decline . After 3 years , total physical activity declined , and only 53.4 % of those reporting sports at baseline continued doing so . Continuation of physical activity over time was associated with the smallest decline in mobility . The observed associations were similar for those with and without chronic disease ( P > 0.3 ) . The conclusions did not change after adjustment for potential confounders , including demographic and lifestyle variables , depression , and cognitive status . CONCLUSIONS Physical activity , and especially a regularly active lifestyle , may slow the decline in mobility performance . A beneficial effect was observed for sports and nonsports activities , independent of the presence of chronic disease
