Furthermore, we found a relationship between physical activity and fallers: residents who walk occasionally or frequently are significantly more often
a faller. Overall, malnourished LTC residents are in general: (1) more prone to be a faller and (2) less active. However, we also observed that the rate of fallers is higher among the relatively active LTC residents. As these observations seem contradictory, we also investigated the role of activity in the relationship between nutritional status and fallers. From this analysis it appeared that in both the active and the inactive group, malnutrition is related to fallers in LTC settings. When specifically looking at the residents who walked occasionally or frequently, the fall rate was higher in those who walked occasionally and highest when concomitantly also malnourished. A plausible explanation for see more the observations with regard
to activity may be that the activity-item of the Braden scale provides rather a rough classification of (in)activity and lacks sensitivity in detecting small differences in the activity level of LTC residents. It is also not surprising that increased activity, as seen in the categories occasionally walking and frequently walking, increases the occasions where a fall can occur compared with the categories bedfast and chairfast (Bueno-Cavanillas et al., 2000, Graafmans et al., 1996, Halfens this website et al., 2007, Halfens et al., 2008, Halfens et al., 2010, Halfens et al., 2009 and Kiely et al., 1998). Therefore, further research is warranted
on this issue and measurement of actual physical activity is preferred. Finally, the influence of nutritional intervention on the relation between nutritional status and fallers was investigated. Specifically in malnourished residents, the results suggest a positive effect of nutritional intervention on the risk of being a faller. This strengthens the observed relationship between nutritional status and fallers. However, future prospective research is essential to further substantiate this finding among LTC residents PLEKHM2 and to gain a better understanding of the potential beneficial role of nutritional intervention and specific nutritional components in falls prevention. At present, few data regarding fall-related nutritional intervention are available, and only vitamin D supplementation has been shown effective in reducing the rate of falls in nursing care facilities (Cameron et al., 2010). There are also some limitations of the present study that need to be mentioned. First, a particular difficulty with cross-sectional studies focusing on relationships is the fact that causality cannot be determined, which can be addressed in future intervention studies.
