More than half of these participants were males (56%, N=19), and only three reported a comorbidity at baseline (hypertension only). Blood glucose and blood pressure changes during follow-up Two hundred and thirty-five (63.9%) and 262 participants (71.2%) had blood glucose measurements documented at the second and fifth-month visits, respectively. Of 28 patients with elevated blood glucose at baseline, only 15 (54%) and 17 (61%) had a blood glucose measurement on the second and fifth-month visits, respectively. The median blood glucose was significantly different between visits (p=0.001). Compared to baseline median blood glucose, the median blood glucose at month two and month five reduced to 5.3mmol/l (IQR 4.8, 6.2) (p=0.041) and 5.2mmol/l (IQR 4.8, 5.9) (p<0.001). The number of patients with elevated blood glucose reduced from 28 (8.0%) at baseline to 9 (3.8%) at the second-month visit and 4 (1.5%) at the fifth-month visit. Amongst those with normal blood glucose at baseline (N=324), 6 (1.8%) had an elevated measurement during month two visit and 2 (0.6%) at month 5 (Figure 1). Overall, 43.3% and 33.8% of participants had elevated baseline systolic and diastolic blood pressure, respectively. The median baseline systolic blood pressure was 117.0
