ABSTRACT
BACKGROUND:
Understanding falls risk in advanced age is critical with people over 80 a rapidly growing demographic. Slow gait and cognitive complaint are established risk factors and together comprise the Motoric Cognitive Risk Syndrome (MCR). This study examined trajectories of gait and cognition and their association with falls over 5 years, and documented MCR in Maori and non-Maori of advanced age living in New Zealand.METHOD:
Falls frequency was ascertained retrospectively at annual assessments. 3 m gait speed was measured and cognition was assessed using the Modified Mini-Mental Status Examination (3MS). Frequency of MCR was reported. Gait and cognition trajectories were modelled and clusters identified from Latent Class Analysis. Generalised linear models examined association between changes in gait, cognition, MCR and falls.RESULTS:
At baseline, 138 of 408 Maori (34%) and 205 of 512 non-Maori (40%) had fallen. Mean (SD) gait speed (m/s) for Maori was 0.66 (0.29) and 0.82 (0.26) for non-Maori. Respective 3MS scores were 86.2 (15.6) and 91.6 (10.4). Ten (4.3%) Maori participants met MCR criteria, compared with 7 (1.9%) non-Maori participants. Maori men were more likely to fall (OR 1.56; 95% CI 1.0-2.43 (P = 0.04) whilst for non-Maori slow gait increased falls risk (OR 0.40; 95% CI 0.24-0.68(P < 0.001). Non-Maori with MCR were more than twice as likely to fall than those without MCR (OR 2.45; 95% CI 1.06-5.68 (P = 0.03).CONCLUSIONS:
Maori and non-Maori of advanced age show a mostly stable pattern of gait and cognition over time. Risk factors for falls differ for Maori, and do not include gait and cognition.
