Determinants of visit-to-visit systolic blood pressure variability among Ghanaians with hypertension and diabetes mellitus

Objective: To identify the determinants of systolic blood pressure variability (SBPV) among Ghanaians. Design: We undertook a secondary analysis of data collected in a prospective study Setting: The study involved patients with hypertension and or diabetes receiving care in five hospitals in Ghana Main outcome measures: We assessed determinants of SBPV among 2,785 Ghanaian patients. We calculated the standard deviation (SD) of systolic BP recordings of 3 to 10 visits per patient over 18 months as a measure of SBPV. A multivariate linear regression analysis was fitted to identify factors independently associated with risk visit-to-visit SBP standard deviation. Results: The mean SD of individual patient visit-to-visit SBP overall was 14.8±6.3 mm Hg. Those with hypertension and diabetes had the highest SD of 15.4 ±6.2 mm Hg followed by 15.2 ±6.5 mm Hg among those with hypertension only and then 12.0 ± 5.2 mm Hg among those with diabetes only, p<0.0001. Factors independently associated with SBPV with adjusted ß coefficients (95% CI) included age: 0.06 (0.03 ­ 0.08) for each year rise in age, eGFR -0.03 (-0.05 - -0.02) for each ml/min rise, low monthly income of <210 Ghana cedis 1.45 (0.43-2.46), and secondary level of education -1.10 (-1.69, -0.50). Antihypertensive classes were associated with SBPV, the strongest associations being hydralazine 2.35 (0.03 ­ 4.68) and Methyldopa 3.08 (2.39 ­ 3.77). Conclusion: Several socio-demographic and clinical factors are associated with SBPV. Future studies should assess the contribution of SBPV to CVD outcomes among indigenous Africans and identify actionable targets.

Contemporary prevalence and predictors of anxiety among patients living with HIVAIDS in Ghana

Objectives: To identify the prevalence and associated factors of anxiety in people living with HIV/AIDS in a tertiary centre in Ghana. Design: The study employed a cross-sectional design. Setting: The study was conducted in the outpatient HIV clinic of a tertiary hospital. Participants: Participants were adult PLWHA receiving OPD care, including those established on combined antiretroviral therapy (cART) and newer patients who were not on cART. Four hundred ninety-five participants aged ≥30 years were consecutively enrolled on the study. Interventions: Demographic and clinical data were collected using standard questionnaires and patient files. Anxiety was assessed using the Hospital Anxiety and Depression Scale (HADS). Multivariate logistic regression analysis was done to identify associated factors. Main outcome measure: Proportion of PLWHA who had HADS score of ≥8 Results: Overall prevalence of anxiety was 61.0% (95%CI: 56.6 ­ 65.3), with no significant difference between recently diagnosed (≤ 6 months, 64.3%) and those with established diagnoses (>6 months, 59.1%). Urban residence (aOR: 1.67, 95%CI: 1.12 ­ 2.51), alcohol use (aOR: 1.64, 95%CI: 1.13 ­ 2.38) and depression (aOR: 13.62, 95%CI: 7.91 ­ 23.45) were independently associated with anxiety. Conclusion: In this sample, 6 in 10 Ghanaian PLWHA had evidence of anxiety. Liaison with the national mental health service for more comprehensive and integrated care and further research into the mental health of PLWHA is recommended to reduce this high burden of anxiety

Understanding the Rise in Cardiovascular Diseases in Africa : Harmonising H3Africa Genomic Epidemiological Teams and Tools : Cardiovascular Topic

Cardiovascular diseases; principally ischaemic heart disease and stroke; are the leading causes of global mortality and morbidity. Together with other non-communicable diseases; they account for more than 60 of global deaths and pose major social; economic and developmental challenges worldwide. In Africa; there is now compelling evidence that the major cardiovascular disease (CVD) risk factors are on the rise; and so are the related fatal and non-fatal sequelae; which occur at significantly younger ages than seen in high-income countries. In order to tackle this rising burden of CVD; the H3Africa Cardiovascular Working Group will hold an inaugural workshop on 30 May 2014 in Cape Town; South Africa. The primary workshop objectives are to enhance our understanding of the genetic underpinnings of the common major CVDs in Africa and strengthen collaborations among the H3Africa teams and other researchers using novel genomic and epidemiological tools to contribute to reducing the burden of CVD on the continent
