Prevalence, risks factors, and control of hypertension in Guinean older adults in 2021: a cross-sectional survey.

BACKGROUND: The incidence of arterial hypertension increases with the aging of the population, but its magnitude remains insufficiently assessed. The aim of this study was to investigate the prevalence of hypertension and associated factors in elderly people in Guinea. METHODS: Data were obtained from a cross-sectional general population survey, conducted among people aged ≥ 60 years. A stratified enumeration area random sample survey was conducted in the four natural regions of Guinea from February to April 2021. This study included an interview on sociodemographic data, and a clinical examination. Hypertension was defined as systolic blood pressure ≥ 140mmHg and/or diastolic blood pressure ≥ 90mmHg or previous diagnosis of hypertension (with or without antihypertensive medication). Hypertension control was defined as blood pressure below 140/90 mmHg during treatment. Age-standardized prevalence was calculated, and logistic regression was used to examine factors associated with hypertension. RESULTS: A total of 1698 adults (1079 men, mean age: 71.6 ± 9.4 years) had at least two blood pressure measurements. The standardized prevalence of hypertension was 61.4% [95% CI: 61.3-61.6], ranging from 52% in Middle Guinea to 67% in Upper Guinea, and was higher in women (65.2%: 65.0-65.4) than in men (59.1%:58.9-59.3). Among those with hypertension, 46.7% were unaware of their condition before the survey and 49.6% were on treatment and only 18.5% had controlled hypertension. Whatever the residence (rural or urban), increasing age, being unmarried, working as a trader or functionary, jobless, living in upper Guinea, low monthly income, intake of extra salt, known diabetic, overweight, and obesity increased the risk of hypertension. In urban area, female sex (AOR: 1.14: 1.12-1.17), living in lower Guinea (AOR: 3.08: 2.97-3.20), being Maninka (AOR: 1.26: 1.21-1.31), being Nguerze (AOR: 1.71: 1.63-1.81) increased the risk of hypertension, but living in forest Guinea (AOR: 0.88: 0.83-0.93), being Soussou (AOR: 0.88: 0.85-0.92) decreased the risk. In rural area, living in forest Guinea (AOR: 2.14: 2.03-2.26), being Soussou (AOR: 1.14: 1.12-1.17) increased the risk of hypertension, but female sex (AOR: 0.96: 0.94-0.98), living in lower Guinea (AOR: 0.87: 0.85-0.89), being Maninka (AOR: 0.94: 0.92-0.97), being Nguerze (AOR: 0.50: 0.47-0.52) decreased the risk. CONCLUSION: Hypertension is a major problem in the elderly population in Guinea, and the level of treatment and control in elderly with known hypertension is inadequate. The place of hypertension among cardiovascular diseases and the identification of associated factors underlines the need to develop innovative approaches to control this major risk factor.

Plantains: Gluco-friendly usage.

Plantains are a staple food for a large proportion of the world's population. Rich sources of carbohydrates, they are considered taboo by most diabetes care providers. For persons living with diabetes, however, they are a preferred food item. This multi country authored article discusses the nutritional and culinary qualities of plantains. It discusses how to consume the fruit in a glucose-safe manner, by reducing the glycaemic load and total caloric load due to a low glycaemic index. Simple ways of modifying plantain preparation and serving are suggested, to help patients take this foodstuff without impacting glucose control.

Diabetes Care During Hajj.

Diabetes mellitus affects over 463 million individuals worldwide. Religious activities such as the Hajj pilgrimage have a major impact on patients with diabetes mellitus, including increasing the risk of hyperglycaemia and hypoglycaemia. This increased risk is due to dietary changes and intense physical activity during pilgrimage while being on antidiabetic medications. Approximately 20% of the pilgrims with underlying illnesses who visit Mecca are diabetic, and complications, such as diabetic ketoacidosis, nonketotic hyperosmolar state, and fatigue/unconsciousness due to hypoglycaemia, have been observed among these patients. Diabetic patients are also at a high risk for foot complications and infections. To avoid any aggravation of the diabetes, a complete biochemical evaluation of the patient must be conducted before Hajj, and the patients must be provided contextualized educational guidance to avert these potential health challenges. This counselling should include the importance of carrying with them at all time their relevant medical history, summaries of the current treatment regimen and emergency snacks. In addition, to reduce the risk of hypoglycaemia, the dosage of insulin should be reduced in selected patients by 20% and that of sulfonylurea should be reduced as needed. Basal insulin and glucagon-like peptide 1 receptor agonists are associated with fewer complications and can be preferentially prescribed. Those patients with type 1 diabetes can continue with the use of insulin pump with suitable education prior to Hajj. For the prevention of foot problems, the use of padded socks and well-fitting shoes is recommended along with an insistence on not walking barefoot. After Hajj, the patient must be followed up, and necessary investigations must be made along with readjustment of insulin dosage in those patients for whom it was reduced. Until the pandemic situation abates, all diabetic patients should avoid making the Hajj journey.

Prevalence and factors associated with hepatitis B in a cohort of HIV-infected children in the Pediatric Department at Donka National Hospital, Guinea.

INTRODUCTION: children pay a heavy price for infection with the hepatitis B virus (HBV). The objective of this work was to determine the prevalence of hepatitis B and describe the associated factors in children at the pediatric department of Donka Hospital. METHODS: this was a cross-sectional study of a cohort of children in the pediatric department of Donka Hospital. HBsAg was performed by using an immunochromatographic method. The analysis of the data was done with software R. The proportions were compared using the Chi-square test or the Fisher test at the significance level of 5%. A logistic regression model was used to explain the prevalence of hepatitis B. RESULTS: one hundred and forty-nine children were recruited between February and July 2017. HBsAg was present in 12 children, i.e. 8.16% (95% CI: 4.29-13.82). The average age was 93.32 months (IQR: 6-180). Male children were the most affected (n = 11, P <0.05), with a sex ratio of 1.01. The majority (51.35%) were on AZT + 3TC + NVP pediatric form and 25% were on AZT + 3TC + NVP adult form and 23.65% on TDF + FTC + EFV. In univariate analysis, ALT, HBsAg positivity, and maternal HBV vaccination status were associated with the prevalence of HBsAg (P <0.05). CONCLUSION: the prevalence of co-infection in children and adults is almost identical in our context. Hence the importance of strengthening preventive measures at all levels, especially the vaccination of children and mothers.

Poor glycemic control in type 2 diabetes in the South of the Sahara: the issue of limited access to an HbA1c test.

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.
