A qualitative focus group study of perceived barriers and benefits to exercise by self-described exercise status among older adults living with HIV.

OBJECTIVES: Although exercise interventions have been shown to improve health outcomes among older people with HIV (PLWH), this population remains highly sedentary. The purpose of this study was to examine the differences in perceived barriers and benefits of exercise among older PLWH by self-identified exercise status. DESIGN: Five focus groups were formed among PLWH: two groups of exercising men, two groups of non-exercising men and one group of women (mixed exercisers and non-exercisers). Themes were analysed in relation to the social-ecological model, utilising the constant comparative approach. SETTING: Patients were recruited from an academic medical centre, HIV clinic and community locations. PARTICIPANTS: PLWH aged 50 or older, diagnosed with HIV for at least 2 years, with no other health conditions that would preclude exercise. PRIMARY AND SECONDARY OUTCOME MEASURES: Determine facilitators, barriers and the ideal environment for exercise or physical activity and determine whether these differ between older PLWH who self-identify as exercisers or non-exercisers. RESULTS: Among 25 men (11 exercisers and 14 non-exercisers) and four women (three non-exercisers and one exerciser), non-exercisers mentioned fewer benefits of exercise (n=46) than exercisers (n=75). Exercisers emphasised positive reinforcement, positive mood change and increased energy as benefits of exercise; interpersonal benefits of exercise were also discussed twice as often by exercisers than by non-exercisers. Non-exercisers emphasised barriers to exercise including lack of motivation, lack of self-efficacy and a negative perception of gym culture. Non-exercisers identified the need for age-appropriate activities as a feature of an ideal exercise environment. Both groups identified time, cost and health-related challenges as barriers to exercise. CONCLUSIONS: Unique exercise barriers and benefits by self-identified exercise status provide important insights into the design of future interventions to initiate and maintain exercise.

Disability Among Middle-Aged and Older Persons With Human Immunodeficiency Virus Infection.

BACKGROUND: Older human immunodeficiency virus (HIV)-infected adults may experience higher rates of frailty and disability than the general population. Improved understanding of the prevalence, risk factors, and types of impairment can better inform providers and the healthcare system. METHODS: HIV-infected participants within the AIDS Clinical Trials Group A5322 HAILO study self-reported disability by the Lawton-Brody Instrumental Activities of Daily Living (IADL) Questionnaire. Frailty was measured by 4-m walk time, grip strength, self-reported weight loss, exhaustion, and low activity. Logistic regression models identified characteristics associated with any IADL impairment. Agreement between IADL impairment and frailty was assessed using the weighted kappa statistic. RESULTS: Of 1015 participants, the median age was 51 years, 15% were aged ≥60 years, 19% were female, 29% black, and 20% Hispanic. At least 1 IADL impairment was reported in 18% of participants, most commonly with housekeeping (48%) and transportation (36%) and least commonly with medication management (5%). In multivariable models, greater disability was significantly associated with neurocognitive impairment, lower education, Medicare/Medicaid insurance (vs private/other coverage), smoking, and low physical activity. Although a greater proportion of frail participants had IADL impairment (52%) compared to non-frail (11%) persons, agreement was poor (weighted kappa <0.18, 95% confidence interval, 0.13, 0.23). CONCLUSION: IADL disability occurs frequently among middle-aged and older HIV-infected adults on effective antiretroviral therapy. Potentially modifiable risk factors (smoking, physical activity) provide targets for interventions to maintain independent living. Systematic recognition of persons at greater risk for disability can facilitate connection to resources that may help preserve independence.
