Abstract Objective: Sedentary behavior (SB) is an independent predictor of all-cause mortality when compared to moderate-to-vigorous physical activity (MVPA). However, the influence of SB on the fear of falling (FOF) has not been investigated. We aimed to evaluate the association of SB and FOF in middle-aged and older adults. We conducted a cross-sectional study. FOF was achieved through the International Fall Efficiency Scale. SB and MVPA were obtained using triaxial accelerometers. Multiple linear regressions were performed to verify the association between SB, MVPA and FOF. Results: 75 middle-aged and older adults participated to the study. Sedentary breaks presented a more important role than the sedentary bouts and the MVPA in FOF. The SB and its pattern present a determinant association with postural balance and FOF in middle-aged and older adults. Hence, our findings reinforce the importance of middle-aged and older adults to perform the recommended amount of MVPA to maintain postural balance and reduce FOF.

Tyg Index

Abstract Background: Leukoaraiosis refers to lesions of high signal intensity in the periventricular and subcortical white matter that result from chronic microvascular ischemic damage to the brain. Increasing evidence suggests that the triglyceride glucose (TyG) index is associated with arterial stiffness and cardiovascular disease, which are both closely related to ischemic arterial damage. We hypothesized that the serum TyG index could be associated with cerebrovascular microangiopathy as measured by leukoaraiosis among middle-aged and older adults.Methods: This cross-sectional study included 2,162 Korean adults aged ≥45 years who participated in a health examination program between 2010 and 2011. TyG index was calculated as Ln (fasting triglycerides (mg/dl) × fasting blood glucose (mg/dl)/2). TyG index quartiles were categorized as follows: Q1, ≤8.12; Q2, 8.13-8.50 Q2, 8.51-8.89; and Q4, ≥8.90. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for leukoaraiosis based on brain MRI scans were calculated across TyG index quartiles using multiple logistic regression analysis.Results: The overall prevalence of leukoaraiosis was 5.4% and increased with serum TyG index quartiles. Compared to the lowest quartile, the ORs (95% CIs) of the highest TyG index quartile for leukoaraiosis was 2.37 (1.17-4.79) after adjusting for age, sex, body mass index, smoking status, alcohol intake, regular exercise, mean arterial pressure, total cholesterol, HDL cholesterol levels, hypertension, and type 2 diabetes.Conclusions: The serum TyG index was positively and independently associated with leukoaraiosis. Our findings indicate that the TyG index might be a useful additional measure for assessing cerebrovascular microangiopathy in clinical settings.

Background: To examine the level of physical activity and sedentary behavior (SB), measured with accelerometers, in older adults from a city in southern Brazil according to sociodemographic and health characteristics.Methods: The sample consisted of 425 older adults (≥63 y) from the EpiFloripa Aging Study. Light physical activity (LPA), moderate to vigorous physical activity (MVPA), and SB were measured with accelerometers over a period of 7 days.Results: The older adults spent two-thirds of the time of use in SB, one-third in LPA, and only 2.1% (95% confidence interval, 1.8–2.2) in MVPA. In the final adjusted model, lower levels of MVPA were observed for women, as well as higher SB and lower LPA and MVPA for those with higher age. There were also trends toward prolonged SB and lower LPA when participants had a higher educational level and toward lower MVPA with higher body mass index.Conclusions: Constant monitoring of physical activity levels and SB using objective measures is recommended and interventions should be directed at the groups most exposed to excessive SB and low levels of MVPA.
