Dropout from physical activity interventions in people living with HIV: a systematic review and meta-analysis

A systematic review and meta-analysis evaluating the effectiveness of minimally supervised home and community exercise interventions in improving physical activity, body adiposity and quality of life in adults living with HIV

People living with HIV (PLWH) are physically inactive and risk cardiometabolic dysfunction. Home and community exercise (HCE) is pragmatic, cost-effective and improves health in varied chronic conditions. This review aimed to synthesize evidence on the effectiveness of minimally supervised HCE for physical activity (PA), adiposity, quality of life (QoL), and other physical and psychological health indices for PLWH.

METHODS

Databases were searched for studies published January 2000 to April 2023. Risk of bias in experimental and quasi-experimental studies was assessed with the Cochrane Risk-of-Bias for Randomized Trials and Risk-of-Bias in Non-Randomized Studies of Interventions tools, respectively. A random-effects meta-analysis was conducted.

RESULTS

From 9648 records, 13 studies (14 HCE groups) with 857 PLWH (average ages 29-56 years) were included; 12 comparator and one single group trial. Aerobic and strength HCE significantly improved PA relative to control by 0.377 units (95 %CI = 0.097, 0.657; p = 0.008) and 1097steps/day (95 %CI = 39.27, 2156.62; p = 0.042). There was a reduction from baseline in percent body fat of 3.36 % (95 %CI = -6.10, 0.42; p = 0.025), but no change in BMI (-0.21 kg/m2; 95 %CI = -0.67, 0.24; p = 0.351) relative to control. HCE improved QoL relative to control in the physical domain by 13points (95 %CI = 6.15, 19.86; p < 0.001), but not in other domains like general health (6.6points; 95 %CI = -1.19, 14.36; p < 0.097). HCE completed at moderate intensity or higher was associated with improvement in outcomes more so than lower intensity HCE. Walking-only interventions were at least as beneficial as other activities. No adverse events were recorded.

CONCLUSION

Minimally supervised HCE can improve PA, body fat, physical QoL and other health indices in PLWH.

Exercise preferences for young people at-risk for and living with HIV: a short report

Exercise can improve physical and mental health for young people at risk for and with HIV, but prevalence rates remain low. This study explored exercise preferences and barriers among young people at risk for and with HIV, and potential gender differences. A total of 129 participants (66.7% male, mean age = 23.8 [SD = 2.1; range: 19-28], 35.7% Black/African American) at-risk for or with HIV were recruited from a larger study and completed an online survey of exercise preferences and barriers. Overall, participants preferred an exercise program that takes place at a fitness center, occurs alone, has a coach/instructor present, is between 30 and 60 minutes, lasts longer than 8 weeks, and includes aerobic and resistance exercises. The fatiguing nature of exercise and cost were common barriers among all genders. Few gender differences emerged. These results should be used to design exercise programs for young adults at risk for and with HIV.

HIV in MOTION: a community of practice on physical rehabilitation for and by people living with HIV and their allies

Background

This paper describes the design, implementation, and evaluation of a community of practice (CoP), HIV in MOTION (HIM), to advance physical activity rehabilitation interventions with adults living with HIV, clinicians, researchers, and representatives from community-based organizations. We attracted a diverse audience of geographically dispersed people living with HIV, clinicians, exercise personnel, and trainees to eight HIM community of practice events that featured the clinical, research, and lived experience of people living with HIV. HIV in MOTION had (a) a domain related to physical rehabilitation, exercise, and social participation for people living with HIV; (b) a community of diverse individuals; and (c) a practice, that is, a series of sustained interactions online and offline, synchronous, and asynchronous. Our team included six diverse people living with HIV, two coordinators, and three academic researchers who planned, prepared, implemented, and evaluated each online session. To evaluate the HIV in MOTION CoP, we employed an evaluation framework composed of five criteria: Goals and Scope, Context and Structure, Process and Activities, Outcomes, and Impact. We collected quantitative and qualitative evaluative data using online evaluation, audiovisual archiving, and participant observations during the debriefing with all members of our team.

Results

We widened the Goals and Scope of the HIV in MOTION CoP to include the HIV narrative of lived experiences, including autopathography, and participant storytelling. In matters of Context and Structure, we received explicit satisfaction with our governance and leadership. Also, being flexible to fit online formats was a productive strategy that made the HIV in MOTION CoP sessions agile and amenable to audiovisual archiving. Our indicators of success in Process, Activities, and Outcomes included participant retention online, elicited verbal interventions and comments in the chat room, and a rate of three repeat visits online. The indicators of success of Impact were the presence of voluntary and unscripted autopathography, the patient storytelling and how it reportedly caused changes in the participants, and the "legitimate peripheral participation" of emerging research and clinical students. In conclusion, we recommend our form of CoP for mixing the knowledge of diverse persons in this area. However, we recommend considering budget and burnout as serious challenges to sustainability.

Preventing cardiovascular disease in midlife women with HIV: An examination of facilitators and barriers to heart health behaviors

Midlife women with HIV (WWH) are disproportionately impacted by cardiovascular disease (CVD), yet little is known about perceptions of CVD risk and the factors that influence engagement in heart health behaviors in this population. Few (if any) studies have used a qualitative approach to examine these perceptions, which has important implications for minimizing the negative impact of HIV-related noncommunicable diseases, the risk for which increases after midlife. Eighteen midlife WWH (aged 40-59) in Boston, MA, completed semistructured interviews to explore perceptions of CVD, HIV, and barriers and facilitators to healthy lifestyle behaviors. Interviews were analyzed via thematic analysis. Participants viewed heart health as important but were unaware of HIV-associated CVD risk. Facilitators included family and generational influences, social support, and access to resources. Physical symptoms, menopause, mental health challenges, and limited financial resources were barriers. Midlife WWH may benefit from tailored CVD prevention interventions that target their unique motivations and barriers to healthy behaviors.

Wireless physical activity monitor use among adults living with HIV in a community-based exercise intervention study: a quantitative, longitudinal, observational study

OBJECTIVES

Our aim was to examine wireless physical activity monitor (WPAM) use and its associations with contextual factors (age, highest education level, social support and mental health) among adults living with HIV engaged in a community-based exercise (CBE) intervention.

DESIGN

Quantitative, longitudinal, observational study.

SETTING

Toronto YMCA, Ontario, Canada.

PARTICIPANTS

Eighty adults living with HIV who initiated the CBE intervention.

INTERVENTION

Participants received a WPAM to track physical activity during a 25-week CBE intervention involving thrice-weekly exercise, supervised weekly (phase 1) and a 32-week follow-up involving thrice-weekly exercise with no supervision (phase 2), completed in December 2018.

OUTCOME MEASURES

Uptake was measured as participants who consented to WPAM use at initation of the intervention. Usage was defined as the proportion of days each participant had greater than 0 steps out of the total number of days in the study. We measured contextual factors using a baseline demographic questionnaire (age, highest education level), and median scores from the bimonthly administered Medical Outcomes Study-Social Support Scale and Patient Health Questionnaire (mental health), where higher scores indicated greater social support and mental health concerns, respectively. We calculated Spearman correlations between WPAM usage and contextual factors.

RESULTS

Seventy-six of 80 participants (95%) consented to WPAM use. In phase 1, 66% of participants (n=76) and in phase 2, 61% of participants (n=64) used the WPAM at least 1 day. In phase 1, median WPAM usage was 50% (25th, 75th percentile: 0%, 87%; n=76) of days enrolled and in phase 2, 23% (0%, 76%; n=64) of days. Correlation coefficients with WPAM usage ranged from weak for age (ρ=0.26) and mental health scores (ρ=-0.25) to no correlation (highest education level, social support).

CONCLUSIONS

Most adults living with HIV consented to WPAM use, however, usage declined over time from phase 1 to phase 2. Future implementation of WPAMs should consider factors to promote sustained usage by adults living with HIV.

Role of Environment on Physical Activity Patterns of Older Adults Living With HIV in New York City

ABSTRACT

The purpose of this study was to survey the physical activity (PA) patterns of older adults with HIV and investigate the relationship between environmental factors and PA in this population. This study was a secondary data analysis from 100 adults, ages 50 years and older, living with HIV in New York City. Descriptive statistics assessed PA patterns. Linear regression assessed the association between environmental factors and time spent in PA. All participants had been living with HIV for 21 years on average, were on antiretroviral therapy, ranged in age from 50 to 71 years, and were 50% female. Participants performed at 75% of their functional capacity ( p < .0001), and females walked less than males ( p < .05). Traffic hazards were the sole environmental predictor of PA participation. Targeted interventions are needed to increase PA in this growing population. Interventions at the policy level should reduce traffic hazards to support PA.

Home-based interventions to promote physical activity for people living with HIV - a systematic review

Although physical activity (PA) improves the physical, mental, and social outcomes of people living with HIV (PLH), multiple barriers prevent them from exercising. In this systematic review, we investigated the effect of home-based interventions to promote physical activity (HBI) among PLH. Randomised trials and quasi-experimental studies published in English until March 2020 were sought in five databases. Independent reviewers performed data extraction, risk of bias assessment and pragmatic-explanatory (PRECIS-2) evaluation of study characteristics. Outcomes included engagement in PA, body composition, cardiorespiratory fitness, strength, metabolic disturbances, and quality of life (QoL). Out of 480 retrieved references, six studies met inclusion criteria. Interventions lasted 12-48 weeks and involved 400 individuals (57.8% women). Ninety-eight (24.5%) participants completed interventions, but dropout rates varied considerably (5.0-54.5%). Resulted showed increased PA (two studies) and improved cardiorespiratory fitness or strength (three and two studies, respectively). Four studies demonstrated reduction of waist circumference and increase in lean body mass. QoL improved in two of three studies. We conclude HBI (aerobic and/or resistance exercises) may contribute to improve PA and/or cardiorespiratory fitness, body composition, strength and QoL of PLH. Further investigation using multi-centre standardised protocols is warranted to provide stronger evidence of their effectiveness in health promotion for PLH.

The Role of the Social Determinants of Health on Engagement in Physical Activity or Exercise among Adults Living with HIV: A Scoping Review

Physical activity (PA) and exercise are an effective rehabilitation strategy to improve health outcomes among people living with HIV (PLWH). However, engagement in exercise among PLWH can vary. Our aim was to characterize the literature on the role of social determinants of health (SDOH) on engagement in PA or exercise among adults living with HIV. We conducted a scoping review using the Arksey and O'Malley Framework. We searched databases between 1996 and 2021. We included articles that examined PA or exercise among adults with HIV and addressed at least one SDOH from the Public Health Agency of Canada Framework. We extracted data from included articles onto a data extraction charting form, and collated results using content analytical techniques. Of the 11,060 citations, we included 41 articles, with 35 studies involving primary data collection 23 (66%) quantitative, 8 (23%) qualitative, and four (11%) mixed methods. Of the 14,835 participants, 6398 (43%) were women. Gender (n = 24 articles), social support (n = 15), and income and social status (n = 14) were the most commonly reported SDOH in the literature with the majority of studies addressing only one SDOH. Future research should consider the intersection between multiple SDOH to better understand their combined impact on engagement in PA or exercise among PLWH.

Combined training improves the diagnostic measures of sarcopenia and decreases the inflammation in HIV-infected individuals

BACKGROUND

HIV-related sarcopenia is an emerging health issue that often remains undiagnosed and can lead to reduced quality of life, independence, and premature death if untreated. This study investigated the effects of a 6 month combined training (resistance plus aerobic exercise) (CT) intervention on diagnostic measures of sarcopenia, including grip strength, appendicular lean mass index (ALMI), and gait speed.

METHODS

Forty participants were randomized into either a CT group (n = 20; age = 38.3 ± 4.9 years) or a control group (CON; n = 20; age = 37.9 ± 5.1 years). Participants in the CT group performed three supervised sessions per week for 6 months, consisting of weekly reverse linear periodized resistance training followed by 20 min aerobic training. Participants in the CON group were instructed to continue with their current lifestyle habits. Assessments were completed at baseline and after 6 months. Statistical analyses were performed using a two-way analysis of covariance (ANCOVA) adjusted for sex and preintervention values. Primary outcomes included grip strength, ALMI, and gait speed. Secondary outcomes were changes in levels of pro-inflammatory cytokines (IL-6 and TNF-α), IGF-1, and myostatin. Associations were explored between changes in inflammatory markers (IL-6 and TNF-α), gait speed, and ALMI with grip strength.

RESULTS

A significant increase in ALMI was found for CT compared with CON (0.29 ± 0.13 kg/m² vs. -0.11 ± 0.14 kg/m² , respectively; P < 0.001). Significant improvements in grip strength (7.86 ± 8.50 kg for CT vs. -1.58 ± 2.47 kg for CON) and gait speed (0.16 ± 0.07 m/s² for CT vs. -0.06 ± 0.52 m/s² for CON; both P < 0.001) were also observed in CT compared with CON. Reduction in inflammatory biomarkers was found in CT compared with CON (IL-6; TNF-α, both P < 0.001). An increase in IGF-1 (74.36 ± 56.64 pg/mm³ for CT vs. 7.19 ± 99 pg/mm³ for CON; P < 0.001) and a decrease in myostatin (-158.90 ± 62.03 pg/mm³ for CT vs. -43.33 ± 146.60 pg/mm³ for CON; P < 0.001) was found following CT compared with the CON group. Change in grip strength was correlated with changes in IL-6 (r = -0.65, P < 0.001), TNF-α (r = -0.63, P < 0.001), gait speed (r = 0.63, P < 0.001), and ALMI (r = 0.54, P = 0.001), but not IGF-1 and myostatin. No adverse events were recorded, and compliance with the CT exercise sessions was high (>85%).

CONCLUSIONS

Combined training appears to be an effective means to counteract sarcopenia and improve various inflammatory markers and growth hormones in people living with HIV.

Retention in RCTs of physical rehabilitation for adults with frailty: a systematic review and meta-analysis

BACKGROUND

Physical rehabilitation (PR) interventions can improve physical function for adults with frailty; however, participant retention rates in randomized controlled trials (RCTs) are unknown. Objective is to summarize participant retention rates in RCTs of PR for adults with frailty. Design is a systematic review and meta-analysis (DOI:10.17605/OSF.IO/G6XR2). Participants are adults ≥ 18 years with frailty. Setting consists of inpatient, outpatient and community-based interventions. Intervention includes any PR intervention.

METHODS

We searched 7 electronic databases from inception to April 15, 2020 for published RCTs. Our primary outcome was participant retention rate to primary outcome measurement. Secondary outcomes included retention by study group, participant retention to intervention completion, reported reasons for attrition and reported strategies for maximizing retention. We completed screening, data extraction and risk of bias (ROB) assessments independently and in duplicate. We conducted a meta-analysis, calculating retention rates and 95% confidence intervals (CIs) using fixed or random-effects models, as appropriate.

RESULTS

We included 21 RCTs, enrolling 1685 adults with frailty (median age 82.5 years (79.0, 82.2), 59.8% female (57.5, 69.8)). Twenty RCTs reported retention data, of which 90.0% (n = 18) had high ROB. The pooled participant retention rate to primary outcome measurement was 85.0% [95%CI (80.0, 90.0), I2 = 83.9%, p < 0.05]. There were no differences by group for retention to the primary outcome [intervention 87.0% (83.0, 91.0), p < 0.05, comparator 85.0% (79.0, 90.0), p < 0.05] or in retention to intervention completion [83.0% (95.0% CI (78.0-87.0), p < 0.05]. Of the 18 studies reporting 24 reasons for attrition, 51.3% were categorized as potentially modifiable by the research team (e.g. low motivation). Only 20.0% (n = 4) of studies reported strategies for maximizing retention.

CONCLUSIONS

In this review of 21 RCTs of PR, we identified acceptable rates of retention for adults with frailty. High retention in PR interventions appears to be feasible in this population; however, our results are limited by a high ROB and heterogeneity.

Effectiveness of self-managed home and community exercise interventions in improving physical activity, body adiposity and related health indices in adults living with HIV: a protocol for a systematic review

BACKGROUND AND OBJECTIVES

Disorders of adipose tissue distribution in people living with the human immunodeficiency virus (HIV) have been associated with significant metabolic derangements that increase their risk of cardiometabolic and other chronic diseases. Systematic reviews focusing on supervised laboratory-based exercise interventions demonstrate that these interventions improve adipose tissue distribution and related health outcomes in people living with HIV (PLWH). However, there is a need to examine the effectiveness of more pragmatic home or community exercise programmes. The aim of this review will be to synthesize existing evidence on the effectiveness of self-managed home or community exercise interventions to improve physical activity levels, adipose tissue distribution and associated health indices in PLWH.

METHODS

This review will encompass interventional studies that evaluate the effect of prescribed exercise programmes performed in the home or community with minimal supervision, by adults living with HIV. The following will be searched from inception: PubMed, Embase, Scopus, Cumulative Index to Nursing and Allied Health Literature, Physiotherapy Evidence Database, SPORTDiscus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Clinicaltrials.gov. Screening of studies and data extraction will be conducted by two independent reviewers. The risk of bias in included studies will be assessed using version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) and the Risk of Bias In Non-Randomized Studies-of Interventions (ROBINS-I) tool for non-randomized concurrently controlled and single-arm interventional studies. A random effects meta-analysis will be used to pool effect estimates for outcomes of interest (measures of physical activity and body adiposity). However, if pooling is deemed inappropriate due to substantial differences between studies, a narrative synthesis will be performed. This protocol is written according to the Preferred Reporting Items for Systematic reviews and Meta-analysis Protocols 2015 statement (see Additional file 1).

DISCUSSION

This review shall provide evidence to support or disapprove the prescription of self-managed exercise interventions in a particularly vulnerable population. We will equally explore the potential impact of technology in improving physical activity outcomes. Our findings could help guide clinicians involved in the care of PLWH in prescribing exercise and inform the design of future trials and research.

A Qualitative Study of Fitness Coaches' Experiences in Community Based Exercise with People Living with HIV

Fitness coaches need to understand the needs of people living with HIV engaged in community-based exercise (CBE) to be competent in developing exercises programs with this population. Our aim was to understand coaches’ experiences engaging in a CBE intervention with PLWH in an urban center in Canada. As part of a broader study, coaches supervised weekly hour-long individualized exercise sessions with PLWH over a six-month period. Using qualitative longitudinal methods, we interviewed coaches up to three times over six months. Transcribed interviews were analyzed cross-sectionally and longitudinally. Seven coaches participated in 15 interviews. Developing confidence, improving health and experiencing a sense of community were viewed as key benefits to PLWH by the coaches. Challenges included accommodating the episodic nature of HIV and ensuring they felt prepared to work with PLWH. Understanding the experiences of coaches engaged in CBE can assist in tailoring exercise programs to meet the needs of PLWH.

Effects of a Health Promotion Intervention on Physical Activity in African American Men Living with HIV: Randomized Controlled Trial

HIV and its treatment with antiretroviral therapy increase the risk of noncommunicable diseases (NCDs) tied to physical inactivity. Older African American men are also at high risk for NCDs. We tested the efficacy of a theory-based intervention to increase adherence to federal aerobic and muscle-strengthening physical activity (PA) guidelines among African American men aged 40 years and older living with HIV. We randomized African American men aged 40 years and older living with HIV to a three-session social cognitive theory-informed health promotion intervention targeting PA or a one-session health awareness control condition. The primary outcome was PA guideline adherence assessed (self-reported) preintervention, immediate postintervention, and 3, 6, and 12 months postintervention. Secondary outcomes were the number of days on which participants reported moderate-intensity aerobic PA, vigorous-intensity aerobic PA, and muscle-strengthening PA in the past 7 days. Of 302 participants, 255 completed the 12-month postintervention measures. Generalized estimated equation logistic regression indicated that the health promotion intervention participants had higher odds of meeting PA guidelines than health awareness control participants, adjusting for baseline adherence (p = 0.011). Health promotion intervention participants also reported more muscle-strengthening PA (p = 0.001), vigorous-intensity aerobic PA (p = 0.049), and moderate-intensity aerobic PA (p = 0.010) than control participants. The rise in self-reported adherence to PA guidelines and improvements in muscle-strengthening and aerobic PA considered separately suggest that a relatively brief behavioral intervention can increase PA among African American men aged 40 years and older living with HIV and potentially curb their risk of NCDs that PA can prevent.

Examining the impact of a community-based exercise intervention on cardiorespiratory fitness, cardiovascular health, strength, flexibility and physical activity among adults living with HIV: A three-phased intervention study

PURPOSE

Our aim was to examine the impact of a community-based exercise (CBE) intervention on cardiorespiratory fitness, cardiovascular health, strength, flexibility, and physical activity outcomes among adults living with HIV.

METHODS

We conducted a longitudinal intervention study with community-dwelling adults living with HIV in Toronto, Canada. We measured cardiopulmonary fitness (V̇O2peak (primary outcome), heart rate, blood pressure), strength (grip strength, vertical jump, back extension, push-ups, curl ups), flexibility (sit and reach test), and self-reported physical activity bimonthly across three phases. Phase 1 included baseline monitoring (8 months); Phase 2 included the CBE Intervention (6 months): participants were asked to exercise (aerobic, strength, balance and flexibility training) for 90 minutes, 3 times/week, with weekly supervised coaching at a community-based fitness centre; and Phase 3 included follow-up (8 months) where participants were expected to continue with thrice weekly exercise independently. We used segmented regression (adjusted for baseline age and sex) to assess the change in trend (slope) among phases. Our main estimates of effect were the estimated change in slope, relative to baseline values, over the 6 month CBE intervention.

RESULTS

Of the 108 participants who initiated Phase 1, 80 (74%) started and 67/80 (84%) completed the intervention and 52/67 (77%) completed the study. Most participants were males (87%), with median age of 51 years (interquartile range (IQR): 45, 59). Participants reported a median of 4 concurrent health conditions in addition to HIV (IQR: 2,7). Participants attended a median of 18/25 (72%) weekly supervised sessions. Change in V̇O2peak attributed to the six-month Phase 2 CBE intervention was 0.56 ml/kg/min (95% Confidence Interval (CI): -1.27, 2.39). Significant effects of the intervention were observed for systolic blood pressure (-5.18 mmHg; 95% CI: -9.66, -0.71), push-ups (2.30 additional push-ups; 95% CI: 0.69, 3.91), curl ups (2.89 additional curl ups; 95% CI: 0.61, 5.17), and sit and reach test (1.74 cm; 95% CI: 0.21, 3.28). More participants engaged in self-reported strength (p<0.001) and flexibility (p = 0.02) physical activity at the end of intervention. During Phase 3 follow-up, there was a significant reduction in trend of benefits observed during the intervention phase for systolic blood pressure (1.52 mmHg/month; 95% CI: 0.67, 2.37) and sit and reach test (-0.42 cm/month; 95% CI: -0.68, -0.16).

CONCLUSION

Adults living with HIV who engaged in this six-month CBE intervention demonstrated inconclusive results in relation to V̇O2peak, and potential improvements in other outcomes of cardiovascular health, strength, flexibility and self-reported physical activity. Future research should consider features tailored to promote uptake and sustained engagement in independent exercise among adults living with HIV.

Action for better brain health among people living with HIV: protocol for a randomized controlled trial

BACKGROUND

Lifestyle changes can protect or improve brain health in older adults. However, sustained lifestyle change is difficult for everyone and may be more difficult for those with executive dysfunction, including some people living with HIV. Thus, the key question is how we can improve adherence to the most promising interventions among people living with HIV experiencing cognitive difficulties. Goal management training is a cognitive rehabilitation program that targets executive dysfunction by teaching goal-directed behaviour and self-management. It is a promising means to improve adherence to lifestyle interventions.

OBJECTIVE

To estimate the extent to which goal management training before a healthy lifestyle program is associated with greater adherence to health recommendations, achievement of health-related goals, and better brain health and health outcomes compared to the healthy lifestyle program alone among people living with HIV.

METHODS

Brain Health Now cohort participants with cognitive difficulties or are not aging successfully are eligible. All participants will be given health resources, a health coach, a goal-setting digital application, and access to an online goal-setting workshop. The intervention group will participate in nine 2-h goal management training sessions and then will enter the healthy lifestyle program. Control participants will enter the healthy lifestyle program directly. A total sample of 100 participants will participate for 12 months. The main outcome is adherence to the healthy lifestyle program, defined as the number of weeks where physical activity adherence targets were met (150 min per week, measured with an activity monitor). Weekly social activities will be captured via self-report with confidential photo validation. We will send weekly health state reports to the participants. Downstream outcomes include cognitive ability, health-related quality of life, mobility, vascular risk profile, and social network size. We will analyze the data using a linear regression model.

DISCUSSION

This project is the first to test whether goal management training can augment adherence to health recommendations among individuals with cognitive difficulties. If successful, behavioural interventions such as goal management training could be implemented as an adjunct to lifestyle interventions in other clinical populations.

TRIAL REGISTRATION

This trial was registered on clinicaltrials.gov (NCT04345484) on April 14, 2020, https://clinicaltrials.gov/ct2/show/NCT04345484?term=NCT04345484&draw=2&rank=1 .

Personalized feedback improves cardiovascular risk perception and physical activity levels in persons with HIV: results of a pilot randomized clinical trial

People with HIV (PWH) have an elevated risk for cardiovascular disease (CVD) compared with the general population. This study examined the feasibility, acceptability and preliminary efficacy of a tailored intervention aimed at increasing CVD risk perception and the adoption of heart-healthy behaviors in PWH. Forty adults were randomized to receive personalized feedback on CVD risk and discussion of risk reduction or health education. Participants were issued pedometers and seen for two treatment sessions. Participants were 60% male and had a mean age of 51.5 years. Ninety percent of participants completed all study sessions indicating good feasibility and acceptability. A medium effect size for the difference between treatment and control groups was found on both the Perceived Risk for Heart Disease (d = .38) and the Rapid Eating and Activity for Patients scales (d = .56) at 12 weeks. Atherosclerotic cardiovascular disease (ASCVD) risk score moderated the effect of treatment, such that at high (but not low) ASCVD risk, active intervention, compared to control, was associated with a greater increase in steps between baseline and both 8 (d = .38) and 12 weeks (d = .55). Findings provide preliminary evidence that tailored interventions delivered by nurses may be effective for primary prevention of CVD in PWH.

Perceived barriers to and facilitators of physical activity in people living with HIV: A qualitative study in a French sample

OBJECTIVES

The benefits of physical activity in people living with HIV (PLHIV) are numerous and are largely reported in the literature. Understanding why PLHIV engage or not in physical activity is key to better accompanying health behaviors. Through a qualitative approach, our study sought to identify barriers to and facilitators of physical activity participation in PLHIV.

METHODS

PLHIV were recruited by purposive sampling. Semi-structured interviews were carried-out in Center and Southern France. The data were analyzed following the principals of thematic analysis. Physical activity level was assessed through questions related to physical activity recommendations and a physical activity questionnaire.

RESULTS

Fifteen semi-structured interviews (seven men and eight women; M_age = 46.6; SD = 10.3) were analyzed. Only a third of our sample was considered physically active with almost half being considered inactive according to recommendations. A multidimensional perspective of physical activity barriers and facilitators emerged. Barriers to and facilitators of physical activity were related to the physical, psychological and socio-environmental domains.

DISCUSSION

Our research sought to better understand the beliefs and attitudes of PLHIV towards physical activity. Physical activity was overall viewed as beneficial by both active and less active PLHIV; however, PLHIV remain insufficiently active. This is discussed through our multidimensional approach of the barriers to and facilitators of physical activity.

The efficacy of a lay health workers – led physical activity counselling program in patients with HIV and mental health problems: a real-world intervention from Uganda

ABSTRACTThis study explored the efficacy of a lay health worker (LHW)-led physical activity (PA) counselling program for inactive patients with HIV/AIDS and mental health problems living in a Ugandan farming community. In total 49 (35 women) community patients (40.0 ± 11.2 years) followed an 8-week once weekly LHW-led PA counselling program based on a self-determination theory and motivational interviewing framework. Participants completed the Simple Physical Activity Questionnaire, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, HIV/AIDS Stress Scale and World Health Organization Disability Assessment Schedule 2 (WHODAS 2) pre- and immediately post-intervention. Small, significant (P < 0.05) effect sizes were found for reductions in HIV/AIDS-related stress (Cohen's d = 0.26) and in global disability (Cohen's d = 0.46). Large effect sizes were observed for reductions in time spent sedentary (Cohen's d = 1.97) and reductions in depressive (Cohen's d = 2.04) and anxiety (Cohen's d = 1.47) symptoms and increases in time spent active (Cohen's d = 1.98). Greater decrease in sedentary time was associated with greater anxiety symptoms reduction (r = 0.32, P = 0.021). In physically inactive patients with HIV/AIDS and mental health problems, an LHW-led PA counselling program reduced stress, anxiety, depression and disability. Randomized controlled trials are needed to confirm these preliminary positive findings.

Effectiveness of Structured Physical Activity Interventions Through the Evaluation of Physical Activity Levels, Adoption, Retention, Maintenance, and Adherence Rates: A Systematic Review and Meta-Analysis

Background: Structured physical activity (PA) interventions (ie, intentionally planned) can be implemented in a variety of facilities, and therefore can reach a large proportion of the population. The aim of the authors was to summarize the effectiveness of structured interventions upon PA outcomes, in addition to proportions of individuals adopting and maintaining PA, and adherence and retention rates. Methods: Systematic review with narrative synthesis and exploratory meta-analyses. Twelve studies were included. Results: Effectiveness on PA levels during adoption (pre- to first time point) showed a trivial standardized effect (0.15 [−0.06 to 0.36]); during maintenance (any time point after the first and >6 mo since initiation) the standardized effect was also trivial with a wide interval estimate (0.19 [−0.68 to 1.07]). Few studies reported adoption (k = 3) or maintenance rates (k = 2). Retention at follow-up did not differ between structured PA or controls (75.1% [65.0%–83.0%] vs 75.4% [67.0%–82.3%]), nor did intervention adherence (63.0% [55.6%–69.6%] vs 77.8% [19.4%–98.1%]). Conclusion: Structured PA interventions lack evidence for effectiveness in improving PA levels. Furthermore, though retention is often reported and is similar between interventions and controls, adoption, maintenance, and adherence rates were rarely reported rendering difficulty in interpreting results of effectiveness of structured PA interventions.

Effects of maximal strength training on bone mineral density in people living with HIV and receiving anti-retroviral therapy: a pilot study

BACKGROUND

Anti-retroviral therapy (ART) is associated with low bone mineral density (BMD) among people living with HIV (PLWHIV). Although physical activity is recommended for improving bone health in patients with reduced BMD, data on effects of strength exercises on low BMD among PLWHIV is scarce. This study therefore aimed to determine the effects of a 12 weeks maximal strength training (MST) on BMD among PLWHIV in Blantyre, Malawi.

METHODS

Twenty-six PLWHIV with reduced BMD were randomised into a training group (TG, n = 15) and control group (CG, n = 11). The TG underwent 12 weeks of MST consisting of 4 sets of 3 to 5 repetitions at 85-90% of one repetition maximum (1RM) 3 times per week. The CG was advised to maintain their usual lifestyle. Measurements of BMD using dual-energy X-ray absorptiometry, 1RM using a squat machine, heart rate using a heart rate monitor, weight, height and body mass index were obtained before and after the intervention in the TG and CG. Descriptive statistics and student's t - tests were used to analyse data.

RESULTS

The study was conducted for 12 weeks. Data of 24 participants [14 (TG) and 10 (CG)] were analysed. At base line, there were no significant differences in age (p = 0.34), height (p = 0.91), weight (p = 0.43) and body mass index (p = 0.34) between participants in the TG and the CG. After the intervention, there were significant improvements in lumbar BMD (p < 0.001) and resting heart rate (p = 0.03) in the TG compared to the CG. There were significant improvements in muscle strength (1 RM) in both the TG (p < 0.001) and the CG (p = 0.01).

CONCLUSIONS

MST improves lumbar BMD and strength in PLWHIV receiving ART in Blantyre, Malawi. MST with a shorter exercise duration of 12 weeks seem to have the potential in treating reduced BMD in PLWHIV.

Beyond the Disease: Contextualized Implications of the COVID-19 Pandemic for Children and Young People Living in Eastern and Southern Africa

The coronavirus disease 2019 (COVID-19) pandemic has created extraordinary challenges and prompted remarkable social changes around the world. The effects of COVID-19 and the public health control measures that have been implemented to mitigate its impact are likely to be accompanied by a unique set of consequences for specific subpopulations living in low-income countries that have fragile health systems and pervasive social-structural vulnerabilities. This paper discusses the implications of COVID-19 and related public health interventions for children and young people living in Eastern and Southern Africa. Actionable prevention, care, and health promotion initiatives are proposed to attenuate the negative effects of the pandemic and government-enforced movement restrictions on children and young people.

Correlates of physical activity stages of change in people living with HIV in a Ugandan community

Purpose: The transtheoretical model (TTM) of behavioral change posits that individuals move through five stages of change when adopting new behaviors: pre-contemplation, contemplation, preparation, action, and maintenance. The aim of this study was to determine the proportion of patients with HIV/AIDS within a Ugandan fishing community in the different physical activity (PA) stages. We also explored differences in variables, motives, and barriers for PA across the stages.Methods: In total, 256 individuals (77 men, 40.5 ± 10.3 years) completed the Patient-centered Assessment and Counseling for Exercise Questionnaire, the Patient Health Questionnaire-9 (PHQ-9) to assess depressive symptoms, and the Alcohol Use Disorders Identification Test. They were also asked about their most important PA motive and barrier.Results: Seventy-five individuals (29%) were in the (pre-)preparatory stages, 140 (55%) in the action and 41 (16%) in the maintenance stage. Those in the (pre-)preparatory stages had higher PHQ-9 total scores (p < 0.001) and were more likely to report barriers than those in the later stages (p < 0.001). Compared with those in the (pre-)preparatory stage, patients in the action stage experienced less body weakness (p = 0.015).Conclusions: Depression and barriers to PA should be considered in people with HIV/AIDS in low-resource settings when implementing interventions to assist them to become more active.Implications for rehabilitationPeople with HIV/AIDS are among the most physically inactive clinical populations.Clinicians should consider depression when motivating patients with HIV in low resourced settings to become active.Clinicians should consider body weakness when motivating patients with HIV in low resourced settings to become active.

Effects of a Combined Exercise Training Program on Health Indicators and Quality of Life of People Living with HIV: A Randomized Clinical Trial

The aim of this study was to evaluate the effects of 16 weeks of combined exercise training (CET) on muscle strength, body composition, depression, anxiety and quality of life of people living with HIV (PLHIV). Twenty-three participants completed the study, 14 in trained group (TG) and 9 in control group (CG). TG consisted of resistance and aerobic training three times a week, while the CG was exposed to recreational activities twice a week. CET promoted increased muscle strength (25% in overall strength) and aerobic capacity (+ 20% in training speed and + 23% in VO₂ during aerobic training; p < 0.05). In addition, TG had better quality of life and reduced depression rates (from 7 subjects with mild, moderate or severe depression to 1 post-training). In conclusion, this pilot data demonstrated that 16 weeks of CET increased muscle strength, and improved depression and quality of life indexes in a small sample of PLHIV.

Feasibility and Impact of a Yoga Intervention on Cognition, Physical Function, Physical Activity, and Affective Outcomes among People Living with HIV: A Randomized Controlled Pilot Trial

The purpose of this pilot randomized controlled trial is to assess the feasibility and impact of a triweekly 12-week yoga intervention among people living with HIV (PLWH). Additional objectives included evaluating cognition, physical function, medication adherence, health-related quality of life (HRQoL), and mental health among yoga participants versus controls using blinded assessors. We recruited 22 medically stable PLWH aged ≥35 years. A priori feasibility criteria were ≥70% yoga session attendance and ≥70% of participants satisfied with the intervention using a postparticipation questionnaire. Two participants withdrew from the yoga group. Mean yoga class attendance was 82%, with 100% satisfaction. Intention-to-treat analyses (yoga n = 11, control n = 11) showed no within- or between-group differences in cognitive and physical function. The yoga group improved over time in HRQoL cognition (P = .047) with trends toward improvements in HRQoL health transition (P =.063) and depression (P = .055). This pilot study provides preliminary evidence of feasibility and benefits of yoga for PLWH.

The effects of aerobic training on the CD4 cells, VO2max, and metabolic parameters in HIV-infected patients: a meta-analysis of randomized controlled trials

INTRODUCTION

To our knowledge, there are no systematic review study with meta-analysis that investigated the influence of training variables on specific outcomes (CD4 cell counts) addressed aerobic training (AT) for HIV+ patients. In this sense, the purpose of this study was to perform a systematic review with meta-analysis of randomized controlled trials on AT in HIV+ patients and to analyze the influence of AT modulating variables on the CD4 cells, VO2max, and metabolic parameters.

EVIDENCE ACQUISITION

Searches were performed in the databases PubMed, ISI Web of Knowledge, SportDiscus, Lilacs, Science Direct, and Scielo.

EVIDENCE SYNTHESIS

Twelve studies involving 438 subjects (78.2% male) were included. Overall, the sample was sedentary (pre-training VO2max of 30.5 mL.kg-1.min-1) with a mean time of virus infection of 66.9 months and mean number of CD4 cells of 467.8 cells/mm3. AT increased the VO2max (ES=1050 [0.455 to 1.64]; P<0.001) and CD4 cell count (ES=0.402 [0.203 to 0.601]; P<0.001). AT for 8-12 weeks appears to be sufficient to increase VO2max, and the highest gains are associated with patients who present higher initial CD4 cell values. There was no difference to metabolic parameters.

CONCLUSIONS

AT did not change the metabolic parameters, but it was AT is able to promote a greater magnitude of improvement in VO2max in the initial weeks of training and a greater increase in the number of CD4 cells in patients who present a better immune condition prior to training.

The efficacy of physical activity counseling in Ugandan patients with HIV and a co-morbid mental disorder: a pilot study

This study explored the efficacy of physical activity (PA) counseling in inactive patients with HIV/AIDS and a co-morbid mental health disorder living in a Ugandan fishing community. We investigated associations between changes in PA, sedentary behavior, mental health burden and quality of life (QoL) following an 8-week once per week PA counseling program using the self-determination theory and motivational interviewing framework. In total 41 (33 women) patients (39.8 ± 10.9years) completed the Simple Physical Activity Questionnaire, Patient Health Questionnaire, Alcohol Use Disorder Identification Test and World Health Organization Quality of Life Questionnaire pre- and post-intervention. Large effect sizes were found for reductions in time spent sedentary (Cohen's d = 2.85) and reductions in depressive symptoms (Cohen's d = 1.47). We also found large effect sizes for increases in time spent walking (Cohen's d = 1.38), in incidental PA such as household chores (Cohen's d = 1.69), and physical health (Cohen's d = 1.38), psychological health (Cohen's d = 0.95), and social relationships. (Cohen's d = 1.39). The more time spent sedentary decreased, the more the psychological health increased (r = -0.33, P = 0.037). In sedentary patients with HIV/AIDS and a co-morbid mental disorder, the mental health burden reduces and QoL improves following PA counseling. Controlled studies are however needed to confirm our findings.

Effect of 8 Weeks of Hospital-Based Resistance Training Program on TCD4+ Cell Count and Anthropometric Characteristic of Patients With HIV in Tehran, Iran: A Randomized Controlled Trial

Ghayomzadeh, M, SeyedAlinaghi, S, Shamsi, MM, Rezaei, S, Earnest, CP, Akbarnejad, S, Taj, L, Mohraz, M, Navalta, JW, Ghasemi, P, and Voltarelli, FA. Effect of 8 weeks of hospital-based resistance raining program on TCD4+ cell count and anthropometric characteristic of patients with HIV in Tehran, Iran: A randomized controlled trial. J Strength Cond Res 33(4): 1146-1155, 2019-We examined the effects of an 8-W circuit resistance training (RES) program using elastic bands and body weight on TCD4+ cell counts and anthropometry in patients with HIV. Patients (N = 21) receiving antiretroviral therapy were randomly assigned to resistance training (RES; n = 14) or control (CON; n = 7) groups. RES (3/W) consisted of training with elastic bands and bodyweight training focusing on major muscle groups. CON received standard care. Statistical analyses were performed using general linear models adjusted for age, sex, length of infection, and respective baseline measures. The primary outcome was TCD4+, and secondary outcomes were anthropometry indices. Tertiary assessments explored Pearson correlations surrounding the relationship between changes in anthropometry and TCD4+. We observed significant increases in TCD4+ count accompanying RES training (105.50 cells·mm, 95% confidence interval [CI], 47.42-163.59), whereas CON significantly decreased (-41.01 cells·mm, 95% CI, -126.78 to 44.76). Significant between-group differences were noted (p < 0.02; n = 0.42). We also observed significant reductions in fat mass for RES (1.18 kg, 95% CI = 1.80 to -0.56) vs. increased fat mass for CON (1.21 kg, 95% CI, 0.31 to 2.11). Significant between-group differences were noted (p = 0.001, n = 0.64). Similar effects were noted for lean body mass. No significant changes were observed for body mass. Significant correlations were observed for fat mass (r = -0.699, p = 0.001) and lean mass (r = 0.553, p = 0.017), but not body mass (r = -0.390, p = 0.109) vs. changes in TCD4+. Our results suggest that the RES program used in this study is effective for improving TCD4+ status and body composition in patients with HIV.

Randomized Controlled Trial of the SystemCHANGE Intervention on Behaviors Related to Cardiovascular Risk in HIV+ Adults

OBJECTIVE

To examine the effect of a lifestyle behavior intervention (SystemCHANGE) on physical activity and diet quality among sedentary people living with HIV (PLHIV). All participants expressed a desire to improve lifestyle health behaviors.

METHODS

One hundred and seven HIV+ adults were randomized to either the intervention (6, in-person, standardized group sessions focusing on improving lifestyle behaviors) or a control condition (general advice on AHA diet and exercise guidelines). All participants wore an ActiGraph accelerometer and completed 24-hour dietary recalls at baseline, 3, and 6 months. Generalized estimating equations were used to examine intervention effects. The primary activity outcome was time spent in moderate-to-vigorous physical activity, and the primary dietary outcome was Healthy Eating Index.

RESULTS

Mean age was 53 years, 65% were male, and 86% African American. Approximately 90% attended at least half of the sessions and 60% attended 5 or more sessions. The intervention did not significantly improve our primary lifestyle behavior endpoints (P ≥ 0.05); however, intervention participants consumed fewer carbohydrates-primarily sugar-sweetened beverages-per day and lost 0.732 kg body weight compared with a 0.153 weight gain in the control group (P = 0.03).

CONCLUSIONS

Among sedentary PLHIV at high risk of cardiovascular disease, the SystemCHANGE intervention reduced daily carbohydrate intake and body weight, but did not increase physical activity or improve overall diet quality. Future work should identify fundamental personal, interpersonal, and contextual factors that will increase physical activity and improve overall diet quality among this population, and integrate these factors into tailored, lifestyle interventions for aging PLHIV.

Effect of a Short-term Lifestyle Modification Program on Quality of Life, Anthropometric Characteristics and CD4+T Cell Count of HIV Infected Patients in Tehran/Iran: A Randomized Controlled Trial

CONTEXT

Increasing physical activity and promoting healthy behaviors may play a key role in reducing the adverse effects of antiretroviral therapy and HIV.

OBJECTIVE

This study investigated the effects of an 8-week lifestyle modification program (LMP) on quality of life, anthropometric characteristics and CD4+T cell count of people living with HIV (PLWH).

METHODS

Thirty PLWH taking ART were randomly assigned to a lifestyle modification program (LMP) (n = 15) or standard care control (CON) group (n = 15). All volunteers underwent body composition, CD4+T cell count measurement and quality of life assessments at the beginning and end of a two-month experimental period.

RESULTS

At follow-up, we observed a significant increase in CD4+T cell count (117.52 cells/mm³; 95% CI, 36.59-198.45) and all subscales and total quality of life score (Short-Form 36 (SF-36) in the LMP group. While we did not observe a significant change in body composition for the LMP group, we did observe a significant increase in body fat (1.75%; 95% CI, 0.15, 2.33) and a reduction in lean body mass (-1.26; 95% CI, -1.26, -2.39) for the CON group.

CONCLUSION

A LMP can be safely used as an effective intervention for improving quality of life and immune competence of PLWH who lack time to participate in a structured exercise regimen.

Predictors of completion of a psychological-behavioral intervention in acute coronary syndrome patients

OBJECTIVE

Dropout from health behavior interventions in patients with heart disease is a major clinical issue that can impact recovery and prognosis. Positive psychology (PP)-based treatments have the potential to promote health behaviors, but predictors of PP intervention completion have not been examined in persons with heart disease.

METHODS

Among 128 patients receiving a phone-based PP intervention to promote physical activity among acute coronary syndrome (ACS) patients, numerous baseline sociodemographic, medical, and psychological variables, along with self-reported pre/post improvements in happiness and optimism (on 0-10 Likert scales) associated with an initial PP exercise, were examined as potential predictors of intervention completion. Logistic and linear regression analyses were used to assess relationships between these predictors and (a) intervention completion (at least 4 of 8 sessions completed) and (b) number of total sessions completed.

RESULTS

No patient characteristic was associated with greater likelihood of completing the PP intervention. However, immediate pre-post change in optimism following the initial exercise was associated with intervention completion (odds ratio = 1.98; 95% confidence interval: 1.28-3.05; p = .002; mean post-exercise increase in optimism 0.79 [SD 1.52] in completers vs. mean optimism decrease of 0.59 [SD 1.42] in non-completers).

CONCLUSIONS

Pre-post change in optimism with a single PP activity predicted completion of an 8-week PP-based health behavior intervention in post-ACS patients. This information could be used clinically by having potential enrollees complete a single PP activity to assess intervention fit.

Management of Reduced Bone Mineral Density in HIV: Pharmacological Challenges and the Role of Exercise

Low bone mineral density is becoming more common among people living with HIV following the use of current antiretroviral therapy drugs such as tenofovir. Although pharmacological therapies used to treat low bone mineral density are associated with adverse effects and may increase the pill burden in people living with HIV who are already burdened by antiretroviral therapy drugs, non-pharmacological strategies to prevent and treat reduced bone mineral density resulting from antiretroviral therapy drugs in people living with HIV have not been fully explored. Despite evidence that exercise is effective in increasing bone mineral density, effects of exercise on low bone mineral density resulting from antiretroviral therapy drugs in HIV infected individuals are still unknown. This review highlights gaps in the strategies used to manage reduced bone mineral density resulting from antiretroviral therapy drugs and focuses on exercise as an alternative or adjunctive strategy.

A pilot randomized aerobic exercise trial in older HIV-infected men: Insights into strategies for successful aging with HIV

BACKGROUND

HIV-infected adults have increased risk for age-related diseases and low cardiorespiratory fitness that can be prevented and improved with exercise. Yet, exercise strategies have not been well studied in older adults with HIV and may require substantial adaptation to this special population.

OBJECTIVE

To determine the safety and efficacy of aerobic exercise in older HIV-infected men in a randomized trial comparing different levels of exercise intensity.

METHODS

We conducted a pilot exercise trial in 22 HIV-infected men ≥50 years of age receiving antiretroviral therapy who were randomized 1:1 to moderate-intensity aerobic exercise (Mod-AEX) or high-intensity aerobic exercise (High-AEX) that was performed three times weekly for 16 weeks in a supervised setting. Primary outcome was cardiorespiratory fitness (VO2peak) measured by treadmill testing. Secondary outcomes were exercise endurance, six-minute walk distance (6-MWD), body composition measured by Dual-energy X-ray absorptiometry (DXA), and fasting plasma levels of lipids and glucose.

RESULTS

VO2peak increased in the High-AEX group (3.6 ±1.2 mL/kg/min, p = 0.02) but not in the Mod-AEX group (0.4 ±1.4 mL/kg/min, p = 0.7) with a significant between group difference (p<0.01). Exercise endurance increased in both the High-AEX group (27 ±11%, p = 0.02) and the Mod-AEX group (11 ±4%, p = 0.04). The 6-MWD increased in both the High-AEX (62 ±18m, p = 0.01) and the Mod-AEX group (54 ±14m, p = 0.01). Changes in VO2peak and 6-MWD were clinically relevant. There were no serious exercise-related adverse events. Dropouts were similar between group (27% overall) and were related to joint pain.

CONCLUSIONS

This pilot exercise trial demonstrates that moderate to high-intensity aerobic exercise in older HIV-infected men increases endurance and ambulatory function. However, increased cardiorespiratory fitness was observed only with high-intensity aerobic exercise despite substantial baseline impairment. Future research is needed to determine exercise strategies in older HIV-infected adults that address advanced aging and comorbidity yet are durable and feasible.

Supervised Physical Activity and Improved Functional Capacity among Adults Living with HIV: A Systematic Review

Physical activity (PA) combats the effects of multimorbidity and antiretroviral therapy in people living with HIV (PLWH), but PLWH often don't meet recommended PA guidelines. The purpose of our review was to investigate whether supervised PA improved functional capacity in PLWH. Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed. Five databases were searched for randomized controlled trials in English, with participants ages 18 years and older, and a supervised PA intervention. A database search yielded 8,267 articles, with 15 eligible for review inclusion. We found a low risk of bias within and across studies. Combined aerobic/progressive resistance training (PRT) improved strength, cardiovascular, and flexibility outcomes; aerobic interventions alone showed no significant improvements; PRT improved strength outcomes; yoga or yoga/meditation showed no outcome differences; and t'ai chi showed cardiovascular and flexibility improvements. We found that supervised PA increased functional capacity in PLWH and that self-report was not a reliable assessment.

Cardiovascular Risk Reduction in Persons Living With HIV: Treatment Development, Feasibility, and Preliminary Results

Persons living with HIV (PLWH) have elevated risks for cardiovascular disease (CVD). Our goal was to develop and pilot test a tailored intervention to improve CVD risk perception and the adoption of heart-healthy behaviors. In-depth qualitative interviews were conducted with 30 PLWH participants to examine learning needs and preferences. An intervention manual was developed and tested in an open pilot with eight participants. Participants were stable on antiretroviral therapy and were recruited from two urban HIV clinics in the northeastern United States. Thematic analysis identified five major themes: (a) tailored structure and design for PLWH, (b) learning needs (specific to HIV), (c) desire for prompts/reminders (to exercise), (d) importance of participant resources, and (e) need for personal evaluation and goal setting. Feasibility and acceptability of the intervention were demonstrated with high session attendance and treatment satisfaction. Further testing is warranted.

Examining the effectiveness of a cognitive intervention to improve cognitive function in a population of older adults living with HIV: a pilot study

OBJECTIVE

The purpose of this randomized-controlled pilot study was to explore the effectiveness of a home-based computerized cognitive training intervention in improving cognitive function in a population of older adults with mild cognitive impairment who are living with HIV.

METHODS

In all, 24 participants were enrolled in this study. All study participants were impaired [defined as Montreal Cognitive Assessment (MoCA) score < 26]; 12 were randomly assigned to a computer-training intervention group and 12 to a control group. The intervention group used a home-based computerized cognitive training program for 8 weeks, while the control group received health-related newsletter via email and follow-up phone calls. Cognitive function was measured at study entry, immediately post intervention, and 8 and 16 weeks post intervention.

RESULTS

This study achieved a 92% retention rate, losing two persons from the intervention group. Participants in the intervention group scored significantly higher on cognitive testing immediately post intervention compared to the control group: F(1, 19) = 4.92, p = 0.04. The partial Eta squared of 0.32 indicates a small to moderate effect size.

DISCUSSION

Cognitive improvement was seen immediately after the intervention, and cognitive improvement was still evident 16 weeks post intervention. Cognitive training could be considered as an option for older adults with HIV experiencing mild cognitive impairment.
