Latin Dance and Working Memory: The Mediating Effects of Physical Activity Among Middle-Aged and Older Latinos.

Background: Physical activity (PA) is a promising method to improve cognition among middle-aged and older adults. Latinos are at high risk for cognitive decline and engaging in low levels of PA. Culturally relevant PA interventions for middle-aged and older Latinos are critically needed to reduce risk of cognitive decline.

BAILA: A Randomized Controlled Trial of Latin Dancing to Increase Physical Activity in Spanish-Speaking Older Latinos.

Background: Latinos are the fastest growing minority group of the older adult population. Although physical activity (PA) has documented health benefits, older Latinos are less likely to engage in leisure time PA than older non-Latino whites. Dance, popular among Latinos, holds promise as a culturally relevant form of PA.

Accelerometer-Measured Sedentary Patterns are Associated with Incident Falls in Older Women.

Background/objective: Falls cause significant problems for older adults. Sedentary time is associated with lower physical function and could increase the risk for falls.

Design: Prospective study.

Associations Between Office Location and Adiposity in Office Workers.

Objective: Evaluate whether having to walk longer distances to common destinations within office buildings is associated with less adiposity and greater occupational physical activity.

Methods: Distances between offices and amenities were measured for 108 office-based workers, as was body fat percentage, waist circumference, number of sedentary breaks at work, and duration and intensity of activity at work.

Results: Being further away from the building entrance was correlated with lower body fat percentage.

Determinants, circumstances and consequences of injurious falls among older women living in the community.

Objective: To identify the risk factors of women who fell with injury relative to women who did not fall or fell without injury and to describe the circumstances and consequences of injurious and non-injurious falls.

Methods: We analysed 5074 older women from the Objective Physical Activity and Cardiovascular Health Study who prospectively tracked their falls using a 13-month calendar. Women with a reported fall were phone interviewed about fall-related details, including injuries.

Hot Deck Multiple Imputation for Handling Missing Accelerometer Data.

Missing data due to non-wear are common in accelerometer studies measuring physical activity and sedentary behavior. Accelerometer output are high-dimensional time-series data that are episodic and often highly skewed, presenting unique challenges for handling missing data. Common methods for missing accelerometry either are ad-hoc, require restrictive parametric assumptions, or do not appropriately impute bouts.

Accelerometer-based predictive models of fall risk in older women: a pilot study.

Current clinical methods of screening older adults for fall risk have difficulties. We analyzed data on 67 women (mean age = 77.5 years) who participated in the Objective Physical Activity and Cardiovascular Health (OPACH) study within the Women's Health Initiative and in an accelerometer calibration substudy.

Physical Activity, Injurious Falls, and Physical Function in Aging: An Umbrella Review.

Purpose: To review and update the evidence of the relationship between physical activity, risk of fall-related injury, and physical function in community-dwelling older people that was presented in the 2018 Physical Activity Guidelines Advisory Committee Scientific Report (PAGAC Report).

Methods: Duplicate independent screenings of 1415 systematic reviews and meta-analyses published between 2006 and 2016 identified from PubMed®, Cochrane Library, and CINAHL databases yielded 111 articles used for the PAGAC Report. The PAGAC Aging Subcommittee members graded scientific evidence strength based upon a five-criteria rubric and assigned one of four grades: strong, moderate, limited, or not assignable.

Sedentary behavior and cardiovascular disease in older women: The Objective Physical Activity and Cardiovascular Health (OPACH) Study.

Background: Evidence that higher sedentary time is associated with higher risk for cardiovascular disease (CVD) is based mainly on self-reported measures. Few studies have examined whether patterns of sedentary time are associated with higher risk for CVD.

Methods: Women from the Objective Physical Activity and Cardiovascular Health (OPACH) Study (n=5638, aged 63-97, mean age=79±7) with no history of myocardial infarction (MI) or stroke wore accelerometers for 4-to-7 days and were followed for up to 4.

Association of Light Physical Activity Measured by Accelerometry and Incidence of Coronary Heart Disease and Cardiovascular Disease in Older Women.

Importance: To our knowledge, no studies have examined light physical activity (PA) measured by accelerometry and heart disease in older women.

Objective: To investigate whether higher levels of light PA were associated with reduced risks of coronary heart disease (CHD) or cardiovascular disease (CVD) in older women.

Design, Setting, And Participants: Prospective cohort study of older women from baseline (March 2012 to April 2014) through February 28, 2017, for up to 4.

Hypertension Treatment and Control and Risk of Falls in Older Women.

Background/objectives: A lower risk of falls is commonly cited as a reason to treat hypertension conservatively in older individuals. We examined the effect of hypertension treatment and control status and measured blood pressure (BP) level on the risk of falls in older women.

Design/setting: Prospective cohort study.

The Scientific Foundation for the Physical Activity Guidelines for Americans, 2nd Edition.

Background: The 2018 Physical Activity Guidelines Advisory Committee Scientific Report provides the evidence base for the Physical Activity Guidelines for Americans, 2nd Edition.

Methods: The 2018 Physical Activity Guidelines Advisory Committee addressed 38 questions and 104 subquestions selected for their public health relevance, potential to inform public policies and programs, maturity of the relevant science, and applicability to the general US population. Rigorous systematic literature searches and literature reviews were performed using standardized methods.

Occupational Physical Activity Opposes Obesity: A Cross-Sectional Modern Replication of the Morris 1953 London Busmen Study.

Objective: Examine the importance of occupational light-intensity physical activity (PA) and short bouts of moderate-vigorous PA (LSBPA), to opposing obesity, including an approximate replication of the London busmen study comparing waist circumference of workers with high versus low levels of occupational activity.

Methods: Working adults wore an accelerometer, completed anthropometric measurements, and provided work schedules. Participants' (n = 435) activity was classified as either occupational or non-occupational minutes, and by intensity.

The 24-Hour Activity Cycle: A New Paradigm for Physical Activity.

The physiologic mechanisms by which the four activities of sleep, sedentary behavior, light-intensity physical activity, and moderate-to-vigorous physical activity (MVPA) affect health are related, but these relationships have not been well explored in adults. Research studies have commonly evaluated how time spent in one activity affects health. Because one can only increase time in one activity by decreasing time in another, such studies cannot determine the extent that a health benefit is due to one activity versus due to reallocating time among the other activities.

CDC's Active People, Healthy Nation: Creating an Active America, Together.

Physical activity can reduce the risk of at least 20 chronic diseases and conditions and provide effective treatment for many of these conditions. Yet, physical activity levels of Americans remain low, with only small improvements over 20 years. The Centers for Disease Control and Prevention (CDC) considered what would accelerate progress and, as a result, developed Active People, Healthy Nation, an aspirational initiative to improve physical activity in 2.

Effect of short bouts of high intensity activity on glucose among adults with prediabetes: A pilot randomized crossover study.

Aim: Few data exist on the effects of vigorous-intensity activity on blood glucose. The study aim was to determine the effects of 2-min and 4-min bouts of vigorous-intensity stair climbing on glucose levels.

Methods: Nine overweight/obese adults with prediabetes (40-64 years, HbA 5.

Sedentary Behavior and Prevalent Diabetes in 6,166 Older Women: The Objective Physical Activity and Cardiovascular Health Study.

Background: We examined associations of sedentary time and sedentary accumulation patterns (ie, how sedentary time is accumulated) with prevalent diabetes in an ethnically diverse cohort of older women.

Methods: Community-dwelling women aged 63-99 (n = 6,116; median age = 79) wore ActiGraph GT3X+ accelerometers 24 h/day for up to 7 days from which we derived average daily sedentary time and three measures of sedentary accumulation patterns: breaks in sedentary time, usual sedentary bout duration, and alpha. Odds ratios (ORs) and 95% confidence intervals (CIs) for prevalent diabetes were estimated using multivariable logistic regression.

A comparative study of fruit and vegetable consumption and physical activity among adolescents in 49 Low-and-Middle-Income Countries.

Physical inactivity and low consumption of fruits and vegetables (FV) during adolescence may persist through adulthood, putting adolescents at risk of developing chronic diseases. Although studies from high-income countries have reported differences in FV consumption and physical activity (PA) between adolescent boys and girls, few exist from low-and-middle-income countries (LMICs). In this study, we examined patterns of FV consumption and PA among adolescent boys and girls in LMICs.

Design: Prospective cohort study with baseline data collection between March 2012 and April 2014.

Setting: Women's Health Initiative cohort in the United States.

Both Light Intensity and Moderate-to-Vigorous Physical Activity Measured by Accelerometry Are Favorably Associated With Cardiometabolic Risk Factors in Older Women: The Objective Physical Activity and Cardiovascular Health (OPACH) Study.

Background: The relationship between light intensity physical activity (PA), which is common in older adults, and cardiovascular disease (CVD) risk factors is unclear. This study examined associations of accelerometer-measured PA intensity with CVD risk factors in older women of different race-ethnicities.

Methods And Results: Cross-sectional analyses were conducted in 4832 women (mean age 78.

An examination of compensation effects in accelerometer-measured occupational and non-occupational physical activity.

Self-report data suggests a large proportion of total physical activity (PA) occurs at work. However, adults with higher levels of occupational PA may compensate by engaging in less non-occupational PA. The study aims were to 1) estimate the intensity, volume, and duration of PA in American adults that occurs at work, and 2) determine if those more active at work are less active outside of work.
