- ItemSociodemographic factors in older adults’ gait speed decline: a gender disaggregate growth curve analysis of the Ibadan Longitudinal Study of Ageing(Sage, 2025) Onyeso, Ogochukwu K.; Alumona, Chiedozie J.; Ojagbemi, Akin; Onyeso, Kelechi M.; Odole, Adesola C.; Victor, Janice; Doan, Jon; Bello, Toyin; Gureje, Oye; Awosoga, OluBackground Gait speed is an important predictor of older adults’ well-being. We estimated the influence of sociodemographic factors on the gait speed decline of community-dwelling older Nigerians. Methods Using the Ibadan Study of Ageing (2007, 2008, and 2009 cycles), we completed a gender disaggregate analysis of sociodemographic influences on participants’ gait speed trajectory using mixed-design ANOVA and growth curve analysis. Results At baseline, 53.2% of participants were female, 61.9% were married, with an average age of 75.5 ± 6.8 years and gait speed of 0.96 ± 0.32 m/s. Gender-specific models showed slower gait speed decline in men (β = −0.05, p < .001) compared to women (β = −0.09, p < .001). Widowhood (β = −0.07, p = .001) for women, high socioeconomic status (β = −0.01, p = .009) for men, and chronic disease burden for women (β = −0.02, p = .010) and men (β = −0.03, p = .008) were significant predictors of gait speed decline. Conclusion Addressing culture-related widowhood and women’s vulnerabilities, improving health coverage, and promoting lifestyle modifications may mitigate mobility decline among older Nigerians.
- ItemSociodemographic determinants of mobility decline among community-dwelling older adults: findings from the Canadian longitudinal study on ageing(SpringerNature, 2025) Onyeso, Ogochukwu K.; Alumona, Chiedozie J.; Odole, Adesola C.; Victor, Janice; Doan, Jon; Awosoga, Olu A.Background Mobility is fundamental to healthy ageing and quality of life. Mobility decline has been associated with functional impairment, falls, disability, dependency, and death among older adults. We explored the sociodemographic determinants of mobility decline among community-dwelling older Canadians. Methods This study was a secondary analysis of a six-year follow-up of the Canadian Longitudinal Study on Ageing (CLSA). Our analysis was based on 3882 community-dwelling older adults 65 years or older whose mobility was measured using timed-up and go (TUG) and 4-meter walk (4MWT) tests at baseline and follow-ups 1 and 2 after three- and six-year intervals, respectively. We analysed the cross-sectional and longitudinal association, main and interaction effects of the participants’ sociodemographic characteristics on mobility decline using chi-square, Pearson’s correlation, mixed-design repeated measures ANOVA, and bivariate and multivariate linear regression tests. Results At baseline, 52% of the participants were female, 70.4% were married, and the average age was 68.82 ± 2.78 years. Mean TUG and 4MWT scores were 9.59 ± 1.98 s and 4.29 ± 0.95 s, respectively. There was a strong positive longitudinal correlation between TUG and 4MWT (r = 0.65 to 0.75, p < 0.001), indicating concurrent validity of 4MWT. The multivariate linear regression (for TUG) showed that older age (β = 0.088, p < 0.001), being a female (β=-0.035, p < 0.001), retired (β=-0.058, p < 0.001), Canadian born (β=-0.046, p < 0.001), non-Caucasian (β=-0.063, p < 0.001), tenant (β = 0.050, p < 0.001), having no spouse/partner (β=-0.057, p < 0.001), household income of $50,000-$99,999 (β = 0.039, p < 0.001), wealth/investment lower than $50,000 (β=-0.089, p < 0.001), lower social status (β=-0.018,p = 0.025), secondary education and below (β = 0.043, p < 0.001), and living in certain provinces compared to others, were significant predictors of a six-year mobility decline. Conclusion Our study underscored the impact of modifiable and non-modifiable sociodemographic determinants of mobility trajectory. There is a need for nuanced ageing policies that support mobility in older adults, considering sociodemographic inequalities through equitable resource distribution, including people of lower socioeconomic backgrounds.
- ItemWell-being of professional older adults' caregivers in Alberta's assisted living and long-term care facilities: a cross-sectional study(Springer Nature, 2023) Awosoga, Olu A.; Odole, Adesola C.; Onyeso, Ogochukwu K.; Doan, Jon; Nord, Christina; Nwosu, Ifeoma B.; Steinke, Claudia; Ojo, Joshua O.; Ekediegwu, Ezinne C.; Murphy, SheliBackground For the care need of older adults, long-term care (LTC) and assisted living (AL) facilities are expanding in Alberta, but little is known about the caregivers’ well-being. The purpose of the study was to investigate the physical health conditions, mental and emotional health (MEH), health behaviour, stress levels, quality of life (QOL), and turnover and absenteeism (TAA) among professional caregivers in Alberta’s LTC and AL facilities. Methods This cross-sectional survey involved 933 conveniently selected caregivers working in Alberta’s LTC and AL facilities. Standardised questions were selected from the Canadian Community Health Survey, Patient Health Questionnaire-9, and Short Form-36 QOL survey revalidated and administered to the participants. The new questionnaire was used to assess the caregivers’ general health condition (GHC), physical health, health behaviour, stress level, QOL, and TAA. Data were analysed using descriptive statistics, Cronbach alpha, Pearson’s correlation, one-way analysis of variance, and multiple linear regression. Results Of 1385 surveys sent to 39 facilities, 933 valid responses were received (response rate = 67.4%). The majority of the caregivers were females (90.8%) who were ≥ 35 years (73.6%), worked between 20 to 40 h weekly (67.3%), and were satisfied with their GHC (68.1%). The Registered Nurses had better GHC (mean difference [MD] = 0.18, p = 0.004) and higher TAA than the Health Care Aides (MD = 0.24, p = 0.005). There were correlations between caregivers’ TAA and each of MEH (r = 0.398), QOL (r = 0.308), and stress (r = 0.251); p < 0.001. The most significant predictors of TAA were the propensity to quit a workplace or the profession, illness, job stress, and work-related injury, F (5, 551) = 76.62, p < 0.001, adjusted R2 = 0.998. Conclusion Reducing the caregivers’ job stressors such as work overload, inflexible schedule, and poor remuneration, and improving their quality of life, health behaviour, and mental, emotional, and physical health conditions may increase their job satisfaction and reduce turnover and absenteeism.
- ItemCaring for paid professional caregivers: investigating the health status of long-term care and assisted living facilities workers in Alberta(University of Lethbridge, 2020) Awosoga, Olu A.; Doan, Jon B.; Steinke, Claudia; Sajobi, Tolulope T.; Murphy, Sheli; Baerg, Scott; Bolarinwa, Remi; Nord, Christina; Varsanyi, Stephanie E.; Dosu, Benjamin; Lucchesi, AnnitaThis is a report on the health status of paid professional caregivers in long-term care (LTC) and Assisted Living (AL) Facilities that was carried out in Alberta Province between June 2017 and October 2019.
- ItemFunctional improvements associated with upper extremity motor stimulation in individuals with Parkinson's disease(Lippincott, Williams, & Wilkins, 2015) Bartoshyk, Patrick J.; De Bruin, Natalie; Brown, Lesley A.; Doan, Jon B.Background: While traditional neurotherapy promotes motor function in people living with Parkinson’s disease (PD), the benefits may be limited by compounding physical, cognitive, and attentional barriers. Since the nontraditional exercise of ice-skating is proving to positively influence motor function and postural control, the purpose of this study was to explore whether the addition of an upper body sensory-driven motor coordination task (stickhandling) would provide upper extremity neuromotor benefit among people with moderate PD. Methods: Seven non-PD control (CTRL) and 22 PD (14 ON-ICE, 8 OFF-ICE) participants completed three trials of a reaching-to-eat (fine motor) task and a button-push (gross motor) task, PRE-and POST-completion of two dynamic – either on- or off-ice – stickhandling tasks. Reaching-to-eat and button-push scores were compared between time periods (PRE, POST) and groups (CTRL, PD ON-ICE, PD OFF-ICE). Results: CTRL participants demonstrated higher scores when compared to the PD groups. Both PD groups demonstrated an improvement in reaching-to-eat and button-push scores immediately following the intervention. Conclusions: These findings suggest that sport-derived exercise programs may provide neuromotor benefit to people living with PD.
