Falls, especially recurrent, cause significant morbidity. Research on falls generally focuses on older adults but patterns of falling may start earlier in life. This study aimed to quantify the prevalence of falls and recurrent falls among late middle-aged community-dwelling adults and identify the socio-demographic, lifestyle and health-related factors associated with recurrent falls.

The Health and Employment After Fifty (HEAF) study is a longitudinal cohort of men and women aged 50–64 years recruited in 2013–14 from across England. At baseline and each of five approximately annual follow-ups, participants reported falls in the preceding year. Participants were categorised as recurrent fallers if they experienced more than one fall on at least two occasions, non-fallers if they never reported a fall, or intermediate fallers otherwise. Multinomial logistic regression explored associations between fall category and potential risk factors, presented as relative risk ratios with 95%CI.

Among 8134 participants, 7051 were eligible for this analysis. The prevalence of any falls ranged from 14–18% across follow-ups. Overall, 437 (6%) were recurrent fallers, 2738 (39%) intermediate and 3876 (55%) non-fallers. Independent predictors of recurrent falls included female gender, unpartnered, unemployed or retired and lack of home ownership. Health-related factors included obesity, fair/poor self-rated health, depression, poor sleep, slow walking speed and memory problems. The final model correctly classified 60% of participants.

Recurrent falls in mid-life were relatively common. Both socio-economic and health-related characteristics, alongside female gender, were identified as predictors, suggesting potential targets for early identification and risk mitigation in this age group.

Increasing physical activity and effectively managing stress can positively impact immunity and may reduce the duration of respiratory tract infections (RTIs). As part of a larger trial, participants accessed a digital behavioural change intervention that encouraged physical activity and stress management to reduce RTIs. We aimed to understand the barriers and facilitators to engaging in physical activity and stress reduction.

A qualitative process analysis from semistructured interviews of the behavioural intervention in a randomised control trial.

Primary care in the UK.

34 participants (aged 18–82 years) in the behavioural intervention arm.

The larger trial involved four interventions: a gel-based antiviral nasal spray; a saline water-based nasal spray; a behavioural intervention; usual care. In this study, we focused on participants allocated to the behavioural intervention. The behavioural intervention included two components: one to increase physical activity (getting active) and another for stress management techniques (healthy paths) to reduce RTIs.

We analysed the interviews using thematic analysis with a critical realist perspective (focusing on). We developed five themes: digital intervention engagement, views on intervention allocation, the role of getting active, the role of healthy paths and benefits reinforcing behaviour. Participants’ views on the relevance and benefit of the behavioural intervention shaped their engagement with the intervention website and behaviour. Facilitators of intervention engagement included awareness of inactivity, goal setting, increasing immunity, positive outcome expectations and benefits from changing behaviour. Barriers to engagement included negative outcome expectations, such as around efficacy of the behaviours.

Overall, the results highlighted the importance of positive expectations for a digital intervention promoting physical activity and stress management for RTI reduction. Future interventions should consider how to clearly communicate a broad range of perceived benefits to users.

The trial was prospectively registered with International Standard Randomized Controlled Trial Number (ISRCTN) registry (17936080).
