Objectives : The objective of this study is to assess the effectiveness of a 6-month nutrition intervention to improve glycemic parameters and inflammation in prediabetic PLWH on stable ART with undetectable HIV viral load.
Methods : A 6-month randomized, controlled nutrition intervention was conducted in prediabetic PLWH. The study participants for the intervention were recruited from the Miami Adult Studies for HIV (MASH) cohort at the FIU-Borinquen Research Clinic. Upon their consent, the participants were randomized into the intervention group or the control group. Participants randomized in the intervention group met once a month for approximately 1 hour where they received medical nutrition therapy, nutrition counseling and nutrition education; participants randomized into the control group received educational material at baseline. Blood was drawn at baseline and at 6-month to measure fasting blood glucose (FBG) and high sensitivity C-reactive protein (hs-CRP).
Results : A total of 38 participants were recruited and randomized into either the intervention group (n=20) or the control group (n=18). We found that the FBG for the 6-month follow-up for the intervention group was significantly lower than the baseline FBG values of the same study group (paired t-test; p=0.031). No significant difference was found in the control group between the baseline and 6-month fasting blood glucose values (p=0.068). Moreover, no significant difference was found in pre/post C-reactive protein (CRP) levels in the intervention or control group (paired t-test; p=0.404 and p= 0.117 respectively). There was a significant difference in CRP levels at baseline (p=0.028) between the study groups but no difference at the 6-month follow up (Mann Whitney U test: p=0.430).
Conclusions : The results from this intervention support the notion that a nutrition intervention is effective in prediabetic PLWH to lower diabetes risk by significantly lowering fasting blood glucose and may be implemented into larger scale interventions; however, no significant changes was seen in hs-CRP values between the 2 groups.
