RESUMO
BACKGROUND: Management of type 2 diabetes remains a challenge in Africa. The objective of this study was to evaluate the prevalence and predictors of poor glycemic control in patients with type 2 diabetes living in sub-Saharan. PATIENTS AND METHODS: This was a cross-sectional study involving 1267 people (61% women) with type 2 diabetes (mean age 58 years) recruited across health facilities in Cameroon and Guinea. Predictors of poor glycemic control (HbA1c ≥7.0% (53 mmol/mol)) were investigated via logistic regressions. RESULTS: The mean body mass index was 27.4 ± 5.8 kg/m(2), and 74% of patients had poor glycemic control. Predictors of poor glycemic control in multivariable regression models were recruitment in Guinea [odd ratio: 2.91 (95% confidence interval 2.07 to 4.11)], age <65 years [1.40 (1.04 to 1.88)], diabetes duration ≥3 years [2.36 (1.74 to 3.21)], treatment with: oral glucose control agents [3.46 (2.28 to 5.26)], insulin alone or with oral glucose control agents [7.74 (4.70 to 12.74)] and absence of a previous HbA1c measurement in Guinea [2.96 (1.30 to 6.75)]. CONCLUSION: Poor control of blood glucose is common in patients with type 2 diabetes in these two countries. Limited access to HbA1c appears to be a key factor associated with poor glycemic control in Guinea, and should be addressed by health policies targeting improvement in the outcomes of diabetes care.
