Item Close relations matter: the association between depression and refugee status in the Canadian Longitudinal Study on Aging (CLSA)(2020) Lin, Shen (Lamson); Kobayashi, Karen M.; Tong, Hongmei; Davison, Karen M.; Arora, Simran R. A.; Fuller‑Thomson, EsmeThis study examined the prevalence and social determinants of depression among refugee and non-refugee adults aged 45–85 in the Canadian Longitudinal Study on Aging. Bivariate analyses and multivariable binary logistic regression analyses were conducted. The prevalence of depression was higher in a sample of 272 refugees (22.1%) and 5059 non-refugee immigrants (16.6%), compared to 24,339 native-born Canadians (15.2%). The adjusted odds ratio (aOR) of depression for refugees were not attenuated when controlling factors such as, (1) socioeconomic status, (2) health conditions and behaviours, (3) social isolation and online social networking (aORs range from 1.61 to 1.70, p’s < 0.05). However, when social support representing close personal relationships was included, the odds of depression for refugees were reduced to non-significance (aOR = 1.30, 95% CI 0.97–1.74, p = 0.08). Refugees’ excess vulnerability to depression is mainly attributable to lower levels of affectionate social support. Targeted interventions in nurturing supportive interpersonal relationships for refugees are warranted.Item Nutrition, immigration and health determinants are linked to verbal fluency among Anglophone adults in the Canadian Longitudinal Study on Aging (CLSA)(2020) Fuller‑Thomson, Esme; Saab, Zahraa; Davison, Karen M.; Lin, Shen (Lamson); Taler, Vanessa; Kobayashi, Karen M.; Tong, HongmeiLater-life cognitive impairment is an important health issue; however, little is known about the condition among diverse groups such as immigrants. This study aims to examine whether the healthy immigrant effect exists for verbal fluency, an indicator of cognitive functioning, among anglophone middleaged and older adults in Canada. Methods: Using from the baseline data of the Canadian Longitudinal Study on Aging (CLSA), multiple linear regression was employed to compare associations among immigrants (recent and long-term) and Canadian-born residents without dementia for two verbal fluency tests, the Controlled Oral Word Association Test (COWAT) and the Animal Fluency (AF) task. Covariates included socioeconomic, physical health, and dietary intake. Results: Of 8,574 anglophone participants (85.7% Canada-born, 74.8% aged 45-65 years, 81.8% married, 81.9% with a post-secondary degree), long-term immigrants (settled in Canada >20 years) performed significantly better than Canadian-born residents for the COWAT (42.8 vs 40.9) but not the AF task (22.4 vs 22.4). Results of the multivariable adjusted regression analyses showed that long-term immigrants performed better than Canadian-born peers in both the COWAT (B=1.57, 95% CI: 0.80-2.34) and the AF test (B=0.57, 95% CI: 0.19-0.95), but this advantage was not observed among recent immigrants. Other factors associated with low verbal fluency performance included being single, socioeconomically disadvantaged, having hypertension, excess body fat, and consuming low amounts of pulses/nuts or fruit/vegetables. Conclusions: Long-term immigrants had higher verbal fluency test scores than their Canadian-born counterparts. Immigration status, social, health and nutritional factors are important considerations for possible intervention and prevention strategies for cognitive impairment.
