Life engagement is an important proxy of successful ageing that may depend on psychological capital factors (e.g., optimism, self-efficacy, and resilience), especially among older adults with severe climate anxiety. This study aimed to assess the association of optimism with life engagement and ascertain whether this relationship is mediated by self-efficacy and resilience among older adults with severe climate anxiety. The data came from the Climate Psychology in Ageing Study 2024, a national survey involving 3994 middle-aged and older adults aged 50 years or over in Ghana. Multistage sampling was used to select the participants across Ghanaian cities, and the Climate Anxiety Scale was used to classify participants into severe, moderate, or mild climate anxiety. A path analysis (through structural equation modelling) was used to quantify the association. The sensitivity of the path model was investigated with data on moderate and mild climate anxiety. Optimism was associated with higher life engagement among older adults with severe and moderate climate anxiety but not among those with mild climate anxiety. Self-efficacy and resilience partially mediated the association of optimism with life engagement among older adults with severe and moderate climate anxiety but fully mediated this relationship among older adults with mild climate anxiety. Psychological capital may be more strongly associated with life engagement among older adults with severe climate anxiety, and policy-driven human development programmes enhancing this capital can facilitate life engagement.

Living in hilly neighbourhoods can be associated with sedentary behaviour, but no study has compared sedentary behaviour and its associations with frailty, chronic diseases, and poor health between flat and hilly neighbourhoods among older adults. This study, therefore, compared older adults’ sedentary behaviour and its association with frailty, poor health, and chronic disease status between low and hilly neighbourhoods. This study utilised a STROBE-compliant cross-sectional design with sensitivity analyses and a common methods bias assessment. The participants were 1,209 people aged 50⁺ years who resided in flat (Ablekuma North, n = 704) and hilly (Kwahu East, n = 505) neighbourhoods in Ghana. The data were analysed with the independent samples t-test and hierarchical linear regression. Older adults in the hilly neighbourhood were more sedentary than those in the flat neighbourhood. The association between sedentary behaviour and chronic disease status was significant in both neighbourhoods, but this relationship was stronger in the hilly neighbourhood. Older adults in the flat neighbourhood reported lower sedentary behaviour at higher frailty (β = -0.18; t = -3.2, p < 0.001), but those in the hilly neighbourhood reported higher sedentary behaviour at higher frailty (β = 0.16; t = 3.54, p < 0.001). Older adults living in the hilly neighbourhood reported higher sedentary behaviour. In the hilly neighbourhood, sedentary behaviour was more strongly associated with frailty and chronic disease status. Older adults in hilly neighbourhoods may need extra support to avoid sedentary behaviour.

The available evidence suggests that social networks can contribute to physical activity (PA) enjoyment, which is necessary for the maintenance of PA over the life course. This study assessed the associations of active and sedentary social networks with PA enjoyment and ascertained whether walkability moderates or modifies these associations. A cross-sectional design compliant with STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) was employed. The participants were 996 community-dwelling older Ghanaians aged 50 years or older. A hierarchical linear regression analysis was used to analyse the data. After adjusting for age and income, the study found that the active social network size (β = 0.09; p < 0.05) and sedentary social network size (β = 0.17; p < 0.001) were positively associated with PA enjoyment. These associations were strengthened by walkability. It is concluded that active and sedentary social networks may better support PA enjoyment in more walkable neighbourhoods. Therefore, enabling older adults to retain social networks and live in more walkable neighbourhoods may be an effective way to improve their PA enjoyment.

Background: Research to date suggests that frailty is higher in women and is associated with functional difficulty. This study builds on the evidence by examining the association between frailty and functional difficulty between low- and higher-income groups and between older men and women in these income groups. Methods: This study adopted a cross-sectional design that complied with the STROBE checklist and included steps against confounding and common methods bias. The population was community-dwelling older adults aged 50 years or older in two urban neighbourhoods in Accra, Ghana. Participants were either in the low-income group in a low socioeconomic neighbourhood (n = 704) or the higher-income group in a high socioeconomic neighbourhood (n = 510). The minimum sample necessary was calculated, and the hierarchical linear regression analysis was utilised to analyse the data. Results: Frailty was positively associated with functional difficulty in the low- and higher-income samples, but this association was stronger in the higher-income sample. Frailty was positively associated with frailty in men and women within the low- and higher-income samples. Conclusion: The association of frailty with functional difficulty was consistent between low- and higher-income samples, although the strength of the relationship differed between these samples. In both income samples, the foregoing relationship was consistent between men and women, although the strength of the relationship differed between men and women.
