Changing trends in cardiovascular risk factors among adults in southern Nigeria

Background: Globally, cardiovascular diseases (CVDs) cause 17.9 million deaths yearly. In nations like Nigeria, diabetes, hypertension, and obesity, coupled with modifiable behaviors such as physical inactivity, unhealthy diet, smoking, and alcohol use, are rising. This study focused on assessing the evolving prevalence and distribution of CVD risk factors among adults in southern Nigeria. Methods: This cross-sectional study, conducted in Port Harcourt, Rivers state, was part of world heart day celebrations over three years (September 2019-September 2023). 309 adults participated, undergoing screening for blood pressure, fasting blood glucose, lipid profile, and body mass index calculated from weight and height measurements. Results: Over three years, 309 subjects (mean age 46.63±12.03) were studied, with 53.40% females and 46.28% males. Most cardiovascular risk factors occurred in the 41-50 age group. Hypertension rose from 65.63% (2019) to 75.29% (2023), dipping to 64.79% (2022). Obesity decreased from 29.69% (2019) to 24.71% (2023), rising to 30.99% (2022). Diabetes increased from 23.44% (2019) to 27.59% (2023), decreasing to 19.71% (2022). Total cholesterol rose from 1.56% (2019) to 2.9% (2023). High LDL increased from 3.12% (2019) to 12.7% (2023). Low HDL and high TRIG decreased from 2019 to 2023. Conclusions: From 2019 to 2023, cardiovascular risk factors like hypertension, obesity, diabetes, and dyslipidemia increased, with a slight fluctuation in 2022. Heightened awareness and preventive measures against adult CVD risk factors are imperative. National education on risk factors is vital for individuals to monitor their blood pressure, weight, cholesterol, and blood sugar levels

Blood pressure control and left ventricular hypertrophy in hypertensive Nigerians

Background : Hypertension is a disease characterized by end-organ complications, leading to high morbidity and mortality in many cases. People with untreated or uncontrolled hypertension often run the risk of developing complications directly associated with the disease. Left ventricular hypertrophy (LVH) has been shown to be a significant risk factor for adverse outcomes both in patients with hypertension and in the general population. We investigated the prevalence and pattern of LVH in a treated hypertensive population at the University College Hospital, Ibadan, Nigeria, using non-hypertensive subjects as control. Design and Setting : A prospective observational study performed at the University College Hospital, Ibadan, Nigeria. Methods : Patients had 6 visits, when at least one blood pressure measurement was recorded for each hypertensive subject and average calculated for systolic blood pressure (SBP) and diastolic blood pressure (DBP) separately. The values obtained were used for stratification of the subjects into controlled and uncontrolled hypertension. Subjects also had echocardiograms to determine their left ventricular mass. Results : LVH was found in 14 (18.2%) of the normotensive group, 40 (20.8%) of the uncontrolled hypertensive group and 14 (24.1%) of the controlled hypertensive group when left ventricular mass (LVM) was indexed to body surface area (BSA). When LVM was indexed to height, left ventricular hypertrophy was found in none of the subjects of the normotensive group, while it was found present in 43 (22.4%) and 14 (24.1%) subjects of the uncontrolled and controlled hypertensive groups, respectively. Significant difference in the prevalence of LVH was detected only when LVM was indexed to height alone. Conclusion : Clinic blood pressure is an ineffective way of assessing BP control. Thus in apparently controlled hypertensive subjects, based on office blood pressure, cardiac structural changes do remain despite antihypertensive therapy. This population is still at risk of cardiovascular events.arri\ue8re-plan: l\u2019hypertension est une maladie caract\ue9ris\ue9e par l\u2019orgue de fi n complications menant \ue0 \ue9lev\ue9 de morbidit\ue9 et mortalit\ue9 dans de nombreux cas.
