Physical Functioning Among Women Aged 80 Years and Older With Previous Fracture

Predictors for functional decline after an injurious fall: a population-based cohort study

Background

The functional consequences of injurious falls are well known. However, studies of the factors that can modify trajectories of disability after an injury from a fall are scarce.

Aims

We aimed to investigate whether sociodemographic and health-related factors may impact this association.

Methods

The study population consisted of 1426 community-dwelling older adults (≥ 60 years) from the SNAC-K cohort study in Stockholm, Sweden. Functional status over 12 years of follow-up was assessed using the number of limitations in basic and instrumental activities of daily living. Sex, cohabitation status, physical activity, and self-rated health were assessed at baseline. Injurious falls were defined as falls requiring healthcare and were assessed over 3 years starting at baseline. Data were analyzed using linear-mixed effects models.

Results

The fastest increase in the number of disabilities was observed in those who had endured an injurious fall and were living alone (β coefficient = 0.408; p < 0.001), been physically inactive (β coefficient = 0.587; p < 0.001), and had poor self-rated health (β coefficient = 0.514; p < 0.001). The negative impact of these factors was more pronounced among fallers compared to non-fallers.

Discussion

Living alone, being physically inactive, and having poor self-rated health magnifies the negative effect of an injurious fall on functional status. Among individuals who endure an injurious fall, the heterogeneity in long-term functional status is substantial, depending on the individuals’ characteristics and behaviors.

Conclusions

These findings emphasize the need for a person-centered approach in care provision and can guide secondary prevention within health care.

Association of Physical Activity and Fracture Risk Among Postmenopausal Women

Importance

Physical activity is inversely associated with hip fracture risk in older women. However, the association of physical activity with fracture at other sites and the role of sedentary behavior remain unclear.

Objective

To assess the associations of physical activity and sedentary behavior with fracture incidence among postmenopausal women.

Design, Setting, and Participants

The Women's Health Initiative prospective cohort study enrolled 77 206 postmenopausal women aged 50 to 79 years between October 1993 and December 1998 at 40 US clinical centers. Participants were observed for outcomes through September 2015, with data analysis conducted from June 2017 to August 2019.

Exposures

Self-reported physical activity and sedentary time.

Main Outcomes and Measures

Hazard ratios (HRs) and 95% CIs for total and site-specific fracture incidence.

Results

During a mean (SD) follow-up period of 14.0 (5.2) years among 77 206 women (mean [SD] age, 63.4 [7.3] years; 66 072 [85.6%] white), 25 516 (33.1%) reported a first incident fracture. Total physical activity was inversely associated with the multivariable-adjusted risk of hip fracture (>17.7 metabolic equivalent [MET] h/wk vs none: HR, 0.82; 95% CI, 0.72-0.95; P for trend < .001). Inverse associations with hip fracture were also observed for walking (>7.5 MET h/wk vs none: HR, 0.88; 95% CI, 0.78-0.98; P for trend = .01), mild activity (HR, 0.82; 95% CI, 0.73-0.93; P for trend = .003), moderate to vigorous activity (HR, 0.88; 95% CI, 0.81-0.96; P for trend = .002), and yard work (HR, 0.90; 95% CI, 0.82-0.99; P for trend = .04). Total activity was positively associated with knee fracture (>17.7 MET h/wk vs none: HR, 1.26; 95% CI, 1.05-1.50; P for trend = .08). Mild activity was associated with lower risks of clinical vertebral fracture (HR, 0.87; 95% CI, 0.78-0.96; P for trend = .006) and total fractures (HR, 0.91; 95% CI, 0.87-0.94; P for trend < .001). Moderate to vigorous activity was positively associated with wrist or forearm fracture (HR, 1.09; 95% CI, 1.03-1.15; P for trend = .004). After controlling for covariates and total physical activity, sedentary time was positively associated with total fracture risk (>9.5 h/d vs <6.5 h/d: HR, 1.04; 95% CI, 1.01-1.07; P for trend = .01). When analyzed jointly, higher total activity mitigated some of the total fracture risk associated with sedentary behavior. Analysis of time-varying exposures resulted in somewhat stronger associations for total physical activity, whereas those for sedentary time were materially unchanged.

Conclusions and Relevance

In older ambulatory women, higher total physical activity was associated with lower total and hip fracture risk but higher knee fracture risk. Mild activity and walking were associated with lower hip fracture risk, a finding with important public health implications because these activities are common in older adults. The positive association between sedentary time and total fracture risk requires further investigation.

The family in face of the elderly's reality of living alone

OBJECTIVE

to understand the family dynamics in face of the reality of the elderly living alone.

METHOD

study of qualitative approach with theoretical reference of symbolic interactionism that involved interviews with families. Data were analyzed by thematic analysis.

RESULTS

six families participated in the study. The discourse analysis originated the following categories: The family respecting their decision making; The family organizing itself to the process of living alone after the age of 80 years; The family experiencing the freedom of living alone.

CONCLUSION

in this study, it was possible to identify the facilitation of the possibility of living alone with preparation and agreements between the family during the family life cycle, leading to the feeling of freedom and quality of life of all members. Nursing, as a science responsible for elaborating care strategies, should work together with families to assist in the planning of care plans based on the individual social reality of the family.
