Background Youth living with HIV (YLHIV) enrolled in HIV treatment experience higher loss to follow-up, suboptimal treatment adherence, and greater HIV-related mortality compared with younger children or adults. Despite poorer health outcomes, few interventions target youth specifically. Expanding access to mobile phone technology, in low- and middle-income countries (LMICs) in particular, has increased interest in using this technology to improve health outcomes. mHealth interventions may present innovative opportunities to improve adherence and retention among YLHIV in LMICs. Objective This study aimed to test the effectiveness of a structured support group intervention, Social Media to promote Adherence and Retention in Treatment (SMART) Connections, delivered through a social media platform, on HIV treatment retention among YLHIV aged 15 to 24 years and on secondary outcomes of antiretroviral therapy (ART) adherence, HIV knowledge, and social support. Methods We conducted a parallel, unblinded randomized controlled trial. YLHIV enrolled in HIV treatment for less than 12 months were randomized in a 1:1 ratio to receive SMART Connections (intervention) or standard of care alone (control). We collected data at baseline and endline through structured interviews and medical record extraction. We also conducted in-depth interviews with subsets of intervention group participants. The primary outcome was retention in HIV treatment. We conducted a time-to-event analysis examining time retained in treatment from study enrollment to the date the participant was no longer classified as active-on-treatment. Results A total of 349 YLHIV enrolled in the study and were randomly allocated to the intervention group (n=177) or control group (n=172). Our primary analysis included data from 324 participants at endline. The probability of being retained in treatment did not differ significantly between the 2 study arms during the study. Retention was high at endline, with 75.7% (112/163) of intervention group participants and 83.4% (126/161) of control group participants active on treatment. HIV-related knowledge was significantly better in the intervention group at endline, but no statistically significant differences were found for ART adherence or social support. Intervention group participants overwhelmingly reported that the intervention was useful, that they enjoyed taking part, and that they would recommend it to other YLHIV. Conclusions Our findings of improved HIV knowledge and high acceptability are encouraging, despite a lack of measurable effect on retention. Retention was greater than anticipated in both groups, likely a result of external efforts that began partway through the study. Qualitative data indicate that the SMART Connections intervention may have contributed to retention, adherence, and social support in ways that were not captured quantitatively. Web-based delivery of support group interventions can permit people to access information and other group members privately, when convenient, and without travel. Such digital health interventions may help fill critical gaps in services available for YLHIV. Trial Registration ClinicalTrials.gov NCT03516318; https://clinicaltrials.gov/ct2/show/NCT03516318

Purpose To determine if physical activity patterns are associated with sleep later at night, and if nighttime sleep is associated with physical activity patterns the next day, among adult women. Methods Women (N=353) living throughout the U.S. wore a wrist and a hip accelerometer for 7 days. Total sleep time (TST, hrs/night) and sleep efficiency (SE, %) were estimated from the wrist accelerometer; and moderate to vigorous physical activity (MVPA, >1040 counts per minute [cpm], hrs/d) and sedentary behavior (SB, <100 cpm, hrs/d) were estimated from the hip accelerometer. Mixed-effects models adjusted for age, race, body mass index (BMI), education, employment, marital status, health status, and hip accelerometer wear time were used to analyze the data. Follow-up analyses using quantile regression were used to investigate associations among women with below average TST and MVPA, and above average SB. Results The average age of our sample was 55.5 (SD = 10.2) years. The majority of participants were white (79%) and married (72%), and half were employed full-time (49%). The participants spent on average 8.9 and 1.1 hours per day in SB and MVPA, respectively, and 6.8 hours per night asleep. No associations were observed between MVPA and SB with nighttime TST or SE. There were no associations between nighttime TST and SE with MVPA or SB the next day. The findings were the same in the quantile regression analyses. Conclusion In free-living adult women, accelerometry-estimated nighttime sleep and physical activity patterns were not associated with one another. Based on our observational study involving a sample of adult women, higher physical activity will not necessarily improve sleep at night on a day-to-day basis (and vice versa).

BackgroundDespite increasing numbers of refugee women-at-risk being resettled and their potential vulnerability, there exists no empirical research into the psychiatric health of this unique subgroup with which to guide policy and practice. This research aimed to investigate psychiatric symptom status of a sample of refugee women-at-risk recently resettled in Australia, as well as factors contributing to symptoms of trauma, anxiety, depression, and somatization. The level of psychiatric symptomatology is compared to reference groups of women from Sudan and Burma, who entered Australia under the Humanitarian Entry Programme, and who did not meet criteria as women-at-risk.MethodsThis is a cross-sectional survey of 104 refugee women-at-risk across several ethnic groups including a demographic questionnaire, the Harvard Trauma Questionnaire, Post-migration Living Difficulties Checklist, and Hopkins Symptom Checklist to assess individual factors, traumatic experiences, post-migration problems, and symptoms of trauma, anxiety, depression, and somatization. A series of multiple hierarchical regression analyses examined factors predicting psychiatric symptoms.ResultsSubstantial proportions of participants reported psychiatric distress in symptomatic ranges, including for traumatization (41%), post-traumatic stress disorder (20%), anxiety (29%), and depression (41%), as well as significant symptoms of somatization (41%). These findings are significantly higher than those derived from reference groups of women from Sudan or Burma, resettled in the same area and utilizing a similar methodology. Higher numbers of trauma events and post-migration living difficulties predicted higher trauma, depression, and somatic (but not anxiety) symptoms. Having children predicted higher trauma, anxiety, and somatic symptoms. Greater English fluency predicted higher anxiety symptoms. Region of birth predicted anxiety and depression symptoms. Age predicted trauma and anxiety symptoms.ConclusionsFindings suggest that recently arrived refugee women-at-risk are at high risk of psychiatric disorders. The results indicate a need for comprehensive psychiatric assessment to identify women in need of treatment very early after resettlement, with implications for medical practice, service delivery, and policy programs.

Background The rapid expansion of direct-to-consumer wearable fitness products (eg, Flex 2, Fitbit) and research-grade sensors (eg, SenseCam, Microsoft Research; activPAL, PAL Technologies) coincides with new opportunities for biomedical and behavioral researchers. Underserved communities report among the highest rates of chronic disease and could benefit from mobile technologies designed to facilitate awareness of health behaviors. However, new and nuanced ethical issues are introduced with new technologies, which are challenging both institutional review boards (IRBs) and researchers alike. Given the potential benefits of such technologies, ethical and regulatory concerns must be carefully considered. ObjectiveOur aim was to understand potential barriers to using wearable sensors among members of Latino, Somali and Native Hawaiian Pacific Islander (NHPI) communities. These ethnic groups report high rates of disparate health conditions and could benefit from wearable technologies that translate the connection between physical activity and desired health outcomes. Moreover, these groups are traditionally under-represented in biomedical research. MethodsWe independently conducted formative research with individuals from southern California, who identified as Latino, Somali, or Native Hawaiian Pacific Islander (NHPI). Data collection methods included survey (NHPI), interview (Latino), and focus group (Somali) with analysis focusing on cross-cutting themes. ResultsThe results pointed to gaps in informed consent, challenges to data management (ie, participant privacy, data confidentiality, and data sharing conventions), social implications (ie, unwanted attention), and legal risks (ie, potential deportation). Conclusions Results shed light on concerns that may escalate the digital divide. Recommendations include suggestions for researchers and IRBs to collaborate with a goal of developing meaningful and ethical practices that are responsive to diverse research participants who can benefit from technology-enabled research methods.

Research has shown that taxi drivers are at risk for numerous health concerns, such as low back and leg pain, linked to their highly sedentary occupation, long work hours and stressors related to the job (e.g. low income, safety threats). The goal of this study was to explore occupational health risks and opportunities for health interventions with taxi drivers using community-based participatory research (CBPR) methods. A mixed methods approach included first a convenience sample of 19 East African taxi drivers participating in focus group discussions. Second, a convenience sample of 75 current taxi drivers (M age = 45.7 years) and 25 non-driver comparison participants (M age = 40.3 years) were recruited to complete a structured self-reported questionnaire and objective measures of health. Health education was provided alongside the research to address common health concerns and to ensure mutual benefit and an action orientation. The focus groups described numerous health concerns that drivers attributed to their occupation, including chronic pain, sleep deprivation, cardiovascular disease, diabetes, kidney disease and eye problems, as the most common. Participants offered ideas for health interventions that include workplace reform and driver education. Quantitative data indicate that 44% of drivers reported their health as 'fair' or 'poor'. Drivers were more likely to report musculoskeletal pain, less sleep, more fatigue and less physical activity as compared to non-drivers. The majority of drivers reported financial and job dissatisfaction. The research provides data to inform targeted health interventions that support the health and safety of taxi drivers.

Physical activity and time spent outdoors may be important non-pharmacological approaches to improve sleep quality and duration (or sleep patterns) but there is little empirical research evaluating the two simultaneously. The current study assesses the role of physical activity and time outdoors in predicting sleep health by using objective measurement of the three variables. A convenience sample of 360 adult women (mean age = 55.38 ±9.89 years; mean body mass index = 27.74 ±6.12) was recruited from different regions of the U.S. Participants wore a Global Positioning System device and ActiGraph GT3X+ accelerometers on the hip for 7 days and on the wrist for 7 days and 7 nights to assess total time and time of day spent outdoors, total minutes in moderate-to-vigorous physical activity per day, and 4 measures of sleep health, respectively. A generalized mixed-effects model was used to assess temporal associations between moderate-to-vigorous physical activity, outdoor time, and sleep at the daily level (days = 1931) within individuals. There was a significant interaction (p = 0.04) between moderate-to-vigorous physical activity and time spent outdoors in predicting total sleep time but not for predicting sleep efficiency. Increasing time outdoors in the afternoon (versus morning) predicted lower sleep efficiency, but had no effect on total sleep time. Time spent outdoors and the time of day spent outdoors may be important moderators in assessing the relation between physical activity and sleep. More research is needed in larger populations using experimental designs.

Europa is a premier target for advancing both planetary science and astrobiology, as well as for opening a new window into the burgeoning field of comparative oceanography. The potentially habitable subsurface ocean of Europa may harbor life, and the globally young and comparatively thin ice shell of Europa may contain biosignatures that are readily accessible to a surface lander. Europa’s icy shell also offers the opportunity to study tectonics and geologic cycles across a range of mechanisms and compositions. Here we detail the goals and mission architecture of the Europa Lander mission concept, as developed from 2015 through 2020. The science was developed by the 2016 Europa Lander Science Definition Team (SDT), and the mission architecture was developed by the preproject engineering team, in close collaboration with the SDT. In 2017 and 2018, the mission concept passed its mission concept review and delta-mission concept review, respectively. Since that time, the preproject has been advancing the technologies, and developing the hardware and software, needed to retire risks associated with technology, science, cost, and schedule.

Latinos living in the United States account for one-third of the uninsured population and face numerous cultural, linguistic, and financial barriers to accessing health care services. Community health fairs have developed to address the unmet need for no- and low-cost services that target prevention and education among underserved communities. The current research describes an ongoing effort in a community in southern California and examines the barriers to health care among participants registering to receive free breast health screenings, one of the major services offered at a 2010 health fair. A total of 186 adult Latina women completed a brief questionnaire assessing their health care utilization and self-reported barriers to engaging in preventive and screening services. Approximately two-thirds of participants reported never receiving or having more than 2 years passing since receiving a preventive health check-up. Participants identified cost (64.5%) and knowledge of locations for services (52.3%) as the primary barriers to engaging in routine health care services. Engaging with health professionals represents a leading way in which adults obtain health information and health fairs offering cancer health screenings represent a culturally appropriate venue for increased cancer health equity. Implications of the current research for future health fairs and their role in community cancer education are discussed.
