A Mixed Methods, Observational Investigation of Physical Activity, Exercise, and Diet Among Older Ugandans Living With and Without Chronic HIV Infection.

The study observed reported and measured activity and diet; it did not test an exercise or diet program, so it cannot show that any intervention works. Participants were purposively sampled from a cohort and were urban Ugandans older than 45 years with cardiovascular risk factors, so findings may not apply to rural, younger, or lower-income adults. Interviewers sometimes gave health education during interviews, which may have shaped participants' answers. Only 10% of transcripts and media were dual coded, so the qualitative coding was not fully checked for reliability. Photographs were not time stamped, so activity pictures could not be matched closely to accelerometer data. Less than half of participants reported yearly income, so the group's income level could not be determined.

The authors reported no real or perceived vested interests related to the article.

Do not conclude that nurse education or tailored exercise advice reduces cardiovascular risk in older Ugandans living with HIV. This was an observational mixed-methods study, not an intervention trial, and measured physical activity and six-minute walk distance did not differ significantly by HIV status.
