Study purposeThe integration of methods to assess daytime physical activity (PA) and sedentary behavior (SB) nighttime sleep would allow the evaluation 24-hour daily using a single device. Accelerometer devices used PA have not been substantially validated evaluate sleep. The objective this study was use polysomnography (PSG) validate commonly accelerometer worn on both wrists hip.MethodsSeventeen participants (50-75years) completed single-night in-home PSG recording while concurrently...

Background: Young men who have sex with (YMSM) are disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition. It remains unclear if PrEP use increases rates of condomless (ie, risk compensation), which may increase infection adherence not optimal. This study aimed to examine whether and were associated change in sexual behaviors a large longitudinal cohort YMSM reporting on multiple partnerships over time. Method: Data obtained from...

Background Total sedentary time varies across population groups with important health consequences. Patterns of accumulation may vary and have differential risks. The purpose this study is to describe patterns older adults living in retirement communities illustrate gender age differences those patterns. Methods Baseline accelerometer data from 307 men women (mean = 84±6 years) who wore ActiGraph GT3X+ accelerometers for ≥ 4 days as part a physical activity intervention were classified into...

Older adults are the least active population group. Interventions in residential settings may support a multi-level approach to behavior change. In cluster randomized control trial, 11 San Diego retirement communities were assigned physical activity (PA) intervention or healthy aging attention condition. Participants 307 over 65 years old. The multilevel PA was delivered with assistance of peer leaders, who trained older adult from communities. Intervention components included individual...

Purpose This study aimed to determine whether physical activity patterns are associated with sleep later at night and if nighttime is the next day among adult women. Methods Women (N = 353) living throughout United States wore a wrist hip accelerometer for 7 d. Total time (TST, hours per night) efficiency (SE, %) were estimated from accelerometer, moderate vigorous (MVPA, >1040 counts minute, h·d−1) sedentary behavior (SB, <100 accelerometer. Mixed-effects models adjusted age, race, body...

Abstract Cerebrovascular disease is associated with an increased likelihood of developing dementia. risk factors are modifiable and may reduce the later-life cognitive dysfunction, however, relationship between cerebrovascular factors, brain integrity cognition remains poorly characterised. Using a UK Biobank sample mid-to-old aged adults, without neurological disease, our structural equation mediation models showed that poor health, indicated by presence was slowed processing speed. This...

Sleep disturbances are associated with poor health outcomes in older adults. The Patient-Reported Outcomes Information System (PROMIS) Disturbance Scale was designed to assess self-reported general sleep and disturbance. objective of this study validate the short-form PROMIS for use among adults living independent-living continuing care retirement communities. Older (N = 307) were recruited from communities San Diego, CA, participate a physical activity intervention. Study participants on...

Adolescent men who have sex with (AMSM) a high rate of HIV diagnoses. An estimated 14.5% infections in the United States are undiagnosed; but among 13- to 24-year-olds, is 51.4%. We describe testing rates and identifies salient individual, family, school, health care influences AMSM.Data were collected as part SMART, an ongoing pragmatic trial online prevention intervention for AMSM (N = 699). Measures included lifetime testing, demographics, sexual behaviors, condom use, education from...

Pre-exposure prophylaxis (PrEP) has been an available biomedical intervention for at-risk adolescents over 2 years; however, progression from awareness to uptake and adherence slow. In response, we map adolescent men who have sex with (AMSM) onto the PrEP Motivation Cascade identify stages intervention.We analyzed PrEP-related attitudinal behavioral data a US national cohort of 1398 AMSM.A majority sample (53.9%) were identified as appropriate candidates. Of those candidates, 51.8%...

Background Adolescent men who have sex with (AMSM), aged 13 to 18 years, account for more than 80% of teen HIV occurrences. Despite this disproportionate burden, there is a conspicuous lack evidence-based prevention programs. Implementation issues are critical as traditional delivery channels (eg, community-based organizations, schools) significant access limitations AMSM. As such, eHealth interventions, such our proposed SMART program, represent an excellent modality delivering...

This study used objective Global Positioning Systems (GPS) to investigate the relationship between pedestrian and vehicle trips physical, cognitive, psychological functioning in older adults living retirement communities. Older (N = 279; mean age 83 ± 6 years) wore a GPS accelerometer for days. Participants completed standard health measures. The Personal Activity Location Measurement System (PALMS) was calculate average daily number of trips, distance, minutes traveled from combined data....

HIV disproportionately impacts young men of color who have sex with men. Keep It Up! (KIU!) is an online intervention that addresses the needs this population. The study objective was to examine acceptability and engagement. Outcomes interests were qualitative quantitative engagement measures, content ratings, paradata. On average, participants rated (4 out 5 stars) (3.5 4) highly. Compared White participants, Black found KIU! more useful, engaging, acceptable; Latino engaging; other...

Purpose: Adolescent sexual minority men (ASMM) are affected disproportionately by HIV, and little is known about their utilization of health care services. We aimed to examine demographic, regional, political influences on the experiences a unique sample racially diverse ASMM from across United States. Methods: Data were collected between April 2018 February 2019 as part baseline survey an ongoing pragmatic trial suite HIV prevention interventions for ASMM. At time analysis, 699 participants...

Childhood sexual abuse (CSA) is associated with a wide range of health outcomes and more prevalent among men who have sex (MSM) compared to women exclusively transgender (TW) cisgender peers; however, there lack consensus regarding an explanatory theoretical model. This analysis examined these models across using baseline data from longitudinal study MSM TW in Chicago (n = 1,035) collected 2015 2019. Severity CSA was measured for two age ranges (prior 13 13–17). Logistic regression negative...

Energy balance is one component of weight management, but passive objective measures caloric intake are non-existent. Given the recent success actigraphy as a measure physical activity construct that relieves participants burden biased self-report, computer scientists and engineers aiming to find intake. Passive sensing food systems have failed go beyond lab into behavioral research in part due low adherence wearing monitoring systems. While system accuracy battery lifetime sine qua non...

Objectives Independently, physical activity (PA), sedentary behavior (SB), and sleep are related to the development progression of chronic diseases. Less is known about how rest-activity behaviors cluster within individuals profiles relate health. In this study we aimed investigate if adult women into based on they accumulate (including accelerometer-measured PA, SB, sleep), participant characteristics health outcomes differ by profile membership. Methods A convenience sample 372 (mean age...

As indications for radiotherapy in mastectomized patients grow, the need greater reconstructive options is critical. Preliminary research suggests an ameliorating impact of lipotransfer on irradiated with expander-to-implant reconstruction. Herein, we present our technique using during expansion stage to facilitate implant placement.A retrospective review postmastectomy reconstruction by one surgeon was performed. All were treated immediate expander and ADM placement at time mastectomy....

Twenty-four hour accelerometer assessments create the opportunity for concurrent measurement of daily behaviors previously examined in isolation, including physical activity (PA), sleep, and sedentary behavior (SB), as well increasing device wear compliance simplifying data capture. Evidence demonstrates that understanding how these make up 24 day will help understand their compositional impact interrelationships on health. This shift research focus calls integration methods to assess PA, SB...
