Supplemental Material for Improving the Identification of Frailty in Long-Term Care Residents: A Cross-Sectional Study by Haritz Arrieta, Chloe Rezola-Pardo, Begoña Sanz, Janire Virgala, Mertxe Lacunza-Zumeta, Ana Rodriguez-Larrad, Jon Irazusta in Biological Research For Nursing

Background: We investigated the associations of replacing sedentary behavior (SB) with physical activity of different intensities on the physical function of octogenarians living in long-term care facilities. Methods: This pooled study recruited 427 older adults aged 80 years and older (69.1% female; body mass index: 27.53). For 345 participants who provided valid data, we assessed device-measured time spent in SB, light-intensity physical activity (LIPA), and moderate to vigorous physical activity (MVPA). We assessed lower limb physical function, strength, mobility, and disability. We used compositional data analysis to investigate the associations of replacing SB with physical activity on the outcomes. Results: Reallocation of SB to LIPA and MVPA was associated with a higher number of 30-second Chair Stand cycles (LIPA: +0.21, MVPA: +1.81; P P P P P P Conclusions: Replacing SB with LIPA or MVPA is associated with physical function and disability of older adults living in long-term care facilities.

Helburu nagusia ariketa fisikoan oinarritutako hiru esku-hartze desberdinen (osagai anitzeko ariketa fisikoko esku-hartzea, dual-task esku-hartzea, eta oinez ibiltzeko esku-hartzea) eraginkortasuna aztertzea da hirugarren adineko egoitzetan bizi diren adineko pertsonetan. Osagai anitzeko ariketa fisikoko eta dual-task esku-hartzeek funtzio fisikoa hobetu zuten arren, lehenengoak bakarrik hobetu zituen hauskortasuna eta afektibitate egoera. Emaitza horiek dual-task esku-hartzearen konplexutasuna eta bertaratze txikiagoarekin batera, ondorioztatzen dugu esku-hartze mota horrek ez duela onura gehigarririk ekartzen hirugarren adineko egoitzetan bizi diren adineko pertsonetan osagai anitzeko ariketa fisikoko esku-hartzeei dagokienez. Bestalde, osagai anitzeko ariketa fisikoko esku-hartzeak eta ibiltzeko esku-hartzeak parte-hartzaileen afektibitate egoera eta bizi-kalitatea hobetu bazuten ere, osagai anitzeko ariketa fisikoko taldeak hobekuntza handiagoak izan zituen funtzio fisikoan, baina era berean, ibiltzea, nahikoa izan zen parte-hartzaileen funtzionaltasuna mantentzeko. Esku-hartzeek ez zuten serumeko BDNF kontzentrazioan aldaketarik eragin. Arestian aipatutakoa kontutan hartuta, ondorioztatu dezakegu hiru esku-hartzeak eraginkorrak direla hirugarren adineko egoitzetan bizi diren adineko pertsonen funtzionaltasuna mantentzeko eta/edo hobetzeko frogatu dugu [EN]One of the challenges of ageing is to maintain independence as you age, and that in particular, is one of the main objectives of active ageing. Medium-term projections show rising rates of disability and dependency in society and, therefore, increasing needs for long-term nursing homes. Older adults living in these homes represent a complex and heterogeneous vulnerable population, with physical and cognitive impairments, along with a higher incidence of frailty, anxiety and depression than those living in the community. In this regard, in the past few years the number of studies into interventions to address the loss of function in older people has increased exponentially. Among the interventions that have so far shown a higher level of evidence are those composed of physical exercise. However, most research on the topic has been carried out on people living in the community and so far no conclusion has been reached on what type of physical exercise is most appropriate for the care of physical and cognitive function for people living in long-term nursing homes. Therefore, the main objective of this research project was to analyze the effectiveness of three different interventions based on physical exercise on the physical and cognitive function, and psycho-affective state of older adults living in long-term nursing homes.
