Impact of Perceived Safety and Barriers on Physical Activity Levels in Community-Dwelling Older Adults During the COVID-19 Pandemic in Singapore: A Cross-Sectional Mixed Methods Study.

This descriptive cross-sectional mixed methods study conducted in Singapore aimed to describe community-dwelling older adults' differences in physical activity (PA) based on perceived safety to exercise, barriers to PA, and preferred modes of PA during a pandemic. Out of 268 older adults, 25.4% felt unsafe to exercise during the pandemic. More participants who felt unsafe were aged 75 years and older (72.1% vs. 57.0%, p = .028) and lacked formal education (54.4% vs. 37.0%, p = .040). Barriers included difficulties exercising with masks, family concerns, and exercise center closures. Those who felt unsafe were significantly more likely to exercise at home and had significantly shorter duration of exercise and walks per week (2.72 vs. 4.50 hr, p = .002). Perceived barriers and exercise preferences should be considered when developing programs to improve older adults' PA during pandemics.

Factors influencing fear of falling in community-dwelling older adults in Singapore: a cross-sectional study.

BACKGROUND: Fear of falling (FoF) has far-reaching implications including activity restriction, functional decline and reduced quality of life. It is a common consequence of falls but may be present even in non-fallers. This study aimed to determine the factors associated with FoF in a segment of Singapore's community-dwelling older adults. METHODS: This descriptive cross-sectional study recruited a convenience sample of adults aged 65 and above from 4 primary care clinics from September 2020 to March 2021. Data were collected on demographic factors, clinical factors such as multi-morbidity, falls characteristics such as history of falls, injuries, and reasons for falls and frailty as determined by the Clinical Frailty Scale (CFS). FoF was measured using the Short Falls Efficacy Scale-International (Short FES-I), cut-off score of 14 and above indicated high FoF. Logistic regression was used to determine factors associated with high FoF. RESULTS: Out of 360 older adults, 78.1% were Chinese and 59.7% females. The mean age was 78.3 years and 76 (21.1%) had a history of falls in the past six months. Almost half (43.1%) were mildly to moderately frail and most (80.6%) had multi-morbidity. The mean FoF score was 15.5 (SD 5.97) and 60.8% reported high FoF. There were statistically significant differences in age, gender, ethnicity, marital status, educational level, use of walking aid, multi-morbidity, frailty status, history of falls within six months and reason for falls between patients who had high FoF versus those who had moderate or low FoF. Logistic regression found that Malay ethnicity (OR = 5.81, 95% CI 1.77-19.13), marital status, use of walking aids (OR = 3.67, 95% CI = 1.54-8.77) and frailty were significant factors associated with high FoF. Compared to those who were never married, the odds of high FoF were significantly higher in married older adults (OR = 6.75, 95% CI 1.39 to 32.76), those who were separated or divorced (OR 10.40, 95% CI 1.13 to 95.76) and those who were widowed (OR = 7.41, 95% CI 1.51 to 36.41). Compared to well older adults, the odds of high FoF were significantly higher in pre frail older adults (OR = 6.87, 95% CI = 2.66-17.37), mildly frail older adults (OR = 18.58, 95% CI = 4.88-70.34) and moderately frail older adults (OR = 144.78, 95% CI = 13.86-1512.60). CONCLUSIONS: The study found that pre frail to moderately frail older adults as determined by CFS have significantly higher risk of high FoF. The demographic factors such as marital status and ethnicity and falls characteristics associated with FoF in this study will be helpful to develop targeted and tailored interventions for FoF.

Does the multidimensional grading system (BODE) correspond to differences in health status of patients with COPD?

STUDY OBJECTIVES: To verify whether and to what extent the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index correlates with a disease-specific index of health status in patients with COPD. DESIGN: Cross-sectional study. SETTING: University-affiliated hospital. PATIENTS: One hundred patients with stable COPD recruited from the outpatient clinic of a single institution. MEASUREMENTS: The BODE index was calculated for each patient using variables obtained within 2 weeks of enrollment. At enrollment, all patients completed the St George's Respiratory Questionnaire (SGRQ). The Kruskal-Wallis test was used to compare health status scores with clinical and functional categories of COPD. The Spearman correlation coefficient (r) was calculated to assess the association between health status scores and clinical or functional variables. RESULTS: Categorizing the BODE scores into 4 quartiles, we found that higher BODE quartiles were associated with higher (worse) SGRQ scores. The differences among the BODE quartiles in health status indexes were significant for total SGRQ as well as all 3 of the SGRQ subscales. In all sections of the SGRQ, scores were moderately to strongly associated with the BODE quartiles (r = 0.27-0.46). In contrast, the association between the SGRQ total, impacts, activity and Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages were weaker (r = 0.27-0.28). There was no significant association between SGRQ symptoms and GOLD stages. CONCLUSIONS: The BODE scoring system corresponds to important differences in health status of patients with COPD. This grading system is better correlated to the health status indexes of the SGRQ than the GOLD staging criteria.
