- Comparison of questionnaire and accelerometer-based assessments of physical activity in patients with heart failure with preserved ejection fraction: clinical and prognostic implicationsPublication . Schmidt, Cristine; Santos, Mario; Bohn, Lucimere; Delgado, Bruno Miguel; Moreira-Gonçalves, Daniel; Leite-Moreira, Adelino; Oliveira, JoséObjective. (i) To compare daily physical activity (PA) levels evaluated by the International Physical Activity Questionnaire (IPAQ) and by triaxial accelerometry in heart failure with preserved ejection fraction (HFpEF) patients; (ii) to describe daily PA patterns based in objective measurements; and (iii) to observe the association between prognostic indicators and PA measurements. Design. This is a cross-sectional study with 24 stable HFpEF patients. PA was assessed through the IPAQ short version and triaxial accelerometer. Time spent in moderate-to-vigorous PA (MVPA) from IPAQ was computed as self-reported walking and MVPA. Prognostic indicators were: distance on the 6-minute-walking test (6MWT), oxygen consumption (VO2) during the test, quality of life (QoL), BNP plasma level, and E/e' ratio. Results. Compared to accelerometry, IPAQ underestimated sedentary time (253 ± 156 vs. 392 ± 104 min/day, p = .001) and overestimated MVPA (44 ± 56 vs. 19.3 ± 26 min/day, p < .001). Accelerometer-derived data showed that HFpEF patients spent 50% of their waking time in sedentary behaviours and 2.5% in MVPA. Of measured surrogate prognostic markers, functional capacity (6MWT, r = 0.652, p = .04; VO2, r = 0.512, p = .02) and QoL (r=-0.490, p = .04) were correlated with MVPA. Conclusions. The IPAQ underestimated sedentary time and over-estimated MVPA in HFpEF patients. Using accelerometer-derived data, HFpEF patients spent only a minority of their time involved in MVPA, which was the only PA pattern positively associated with prognostic indicators.
- Dynamic Balance and Mobility Explain Quality of Life in HFpEF, Outperforming All the Other Physical Fitness ComponentsPublication . Schmidt, Cristine; Santos, Mario; Bohn, Lucimere; Delgado, Bruno Miguel; Moreira-Gonçalves, Daniel; Leite-Moreira, Adelino; Oliveira, JoséBackground Physical fitness is an important determinant of quality of life (QoL) in heart failure with preserved ejection fraction (HFpEF) patients. However, how the different physical fitness components correlate with the specific dimensions of QoL in HFpEF patients remains unknown. Objective To evaluate the association between different physical fitness components and QoL dimensions in HFpEF patients, and, assess which physical fitness components were independently associated to QoL. Methods Patients with HFpEF were assessed for physical fitness [dynamic balance and mobility (8-foot-up-and go test), upper body strength (handgrip), cardiorespiratory fitness (CRF) (6-minute-walking test) and body composition (body mass index)] and for QoL (Minnesota Living With Heart Failure Questionnaire). Partial correlation was used to verify the association between physical fitness components and QoL dimensions. The determination of independent predictors in QoL dimensions was assessed through stepwise multivariate linear regression analysis. Statistical significance was set at p<0.05. Results Both CRF and dynamic balance and mobility are significantly associated with the total score and physical dimensions of QoL (p<0.05), but only dynamic balance and mobility were concomitantly associated with the emotional dimension (r=0.597; p=0.004). Dynamic balance and mobility were independently associated with total score (β=0.651; r2=0.424; p=0.001), physical (β=0.570; r2=0.324; p=0.04) and emotional (β=0.611; r2=0.373 p=0.002) dimensions of QoL. Conclusion Our data suggests that dynamic balance and mobility better assess QoL than CRF, which is commonly measured in clinical practice. Whether interventions specifically targeting dynamic balance and mobility have different impacts on QoL remains unknown. (Arq Bras Cardiol. 2020; 114(4):701-707).
- Predictors of Lower Depression Levels in Older Adults During COVID-19 LockdownPublication . Bohn, Lucimere; Gomes, Sérgio; Neto, Elzier Sampaio de Queiroz; Lage, Ana Carolina Silveira de Souza; de Freitas, Maria das Dores Bezerra; Magalhães, Fabíola de Paula; Mota, Jorge; Soares-Miranda, LBackground: Social distancing during the COVID-19 pandemic may lead to adverse mental health consequences, such as depression, among older adults. This study aimed to investigate the predictors of lower depression scores in older adults living under lockdown. Methods: 1,123 older Brazilian adults were cross-sectionally assessed for depression, physical activity (PA), pet ownership (dogs, cats, and birds), ability to make video calls, leaving home during lockdown, and not living alone. The statistical procedures included linear regression and analysis of covariance (ANCOVA). Results: After adjusting for age, sex, and race, moderate to vigorous PA (β = -0.014, p < .001), it was found that PA (β = -0.905, p < .001) and dog ownership (β = -0.545, p = .004) were associated with lower depression. No association was observed between depression and other conditions. Conclusions: With the likelihood of subsequent COVID-19 waves, remotely delivered PA programs might be a strategy to counteract the negative psychological effects of lockdown on older adults.
