Factors associated with self-reported capacity to walk, jog and run in individuals with systemic lupus erythematosus

Dose-response relationship between sedentary time and anxiety and the moderating effect of a 10-min walk: a cross-sectional study

BACKGROUND

The effectiveness and generalisability of conventional anxiety treatment programmes is low across the population, and it is important to explore the research evidence for preventing and improving anxiety from a physical activity perspective. This study examined sedentary activity's impact on anxiety, its dose-response relationship, and the interactive effects of 10-min walks and sedentary duration on anxiety.

METHODS

A total of 28,977 individuals were chosen from the Chinese Psychological and Behavioural Study of the Population (PBICR) 2022. Binary logistic regression analyzed the association between sedentary time and anxiety and the interaction effect of daily 10-min walks and sedentary time on anxiety. Restricted cubic spline model explored the dose-response relationship between sedentary time and anxiety risk.

RESULTS

Participants who were sedentary for > 6 h had a 25.1% increased risk of anxiety (OR = 1.251). Among those sedentary for > 6 h, each additional hour of sedentary time increased the risk of anxiety by 4.3%. However, for participants sedentary for ≤ 6 h, sedentary time did not increase the risk of anxiety. A non-linear J-shaped relationship between sedentary time and the risk of anxiety (non-linear trend p < 0.001). Among individuals who were sedentary for > 6 h, those who walked more than 10 min on ≤ 5 days per week had a 67.1% increased risk of anxiety (OR = 1.671), whereas those who walked more than 10 min on > 5 days per week experienced a 19% decreased risk of anxiety (OR = 0.810). For individuals sedentary for ≤ 6 h, each additional day of walking for > 10 min reduced the risk of anxiety by 9.8%. Among those sedentary for > 6 h, each additional day of walking for > 10 min reduced the risk of anxiety by 10.3%.

CONCLUSIONS

A non-linear J-shaped relationship between sedentary time and anxiety risk. Walking for more than 10 min was associated with fewer negative effects of sedentary activity on anxiety. It is recommended that future empirical studies with a higher level of evidence be conducted to further confirm the effect of 10-min walking days on anxiety risk through empirical studies and to use specialized wearable devices to improve the accuracy of the measurements. By further exploring the effects of sedentary time and 10-min walking days on anxiety risk, the most effective treatment programs based on physical activity interventions can be established to reduce the prevalence of anxiety in the whole population.

Factors affecting patient activation among patients with systemic lupus erythematosus

There are limited published studies on patient activation among patients with systemic lupus erythematosus (SLE) in China. Disease activity can significantly influence a patient's perception of their condition, subsequently impacting patient activation. However, the mechanisms through which disease activity influences patient activation remain poorly understood. This study aimed to investigate patient activation among patients with SLE in China and explore the influencing factors. We conducted a cross-sectional study from June to December 2021 at a rheumatology and immunology department of a tertiary hospital in Chengdu, China. Data were collected by questionnaire, including general information, disease activity, quality of chronic illness care, health literacy, self-efficacy, motivation, social support, and patient activation. A patient activation model was constructed based on the conceptual framework derived from the individual and family self-management theory. To evaluate the moderating effect of disease activity on patient activation model, participants were divided into two subgroups (low disease activity group and high disease activity group). 426 SLE patients were included. The mean score of patient activation among SLE patients was 63.28 ± 11.82, indicating that most SLE patients lacked skills and confidence to stick with health-promoting behaviors. Health literacy, social support, and self-efficacy had the greatest effect on patient activation. In the multi-group analysis, social support and health literacy contributed more to patient activation in SLE patients with high and low disease activity, respectively. Patient activation among SLE patients in China was at the third level. Healthcare professionals should help them adhere to health-promoting behaviors. Health literacy, social support, and self-efficacy are vital factors for patient activation. These factors should be prioritized based on disease activity when developing individually tailored interventions for patient activation.
