    bstract Introduction: Abnormal blood pressure (BP) dipping patterns are associated with increased cardiovascular risk among Africans. This study determined the association between BP dipping patterns and hypertension-mediated organ damage among patients with newly-diagnosed hypertension. Methods: Ambulatory BP monitoring and echocardiography were carried out on 120 participants. Participants were categorized based on the ratio of night-time to day-time systolic BP into 4 patterns: Normal dipper (≥ 10% but < 20%), non-dippers (≥ 0% but < 10%), reverse dippers (<0%) and extreme dippers (≥ 20%). Result: Fifty-one (42.5%) were males, the mean age and body mass index were 44.2±9.8years and 27.1±4.4kg/m2 respectively. The non-dipping pattern was the most prevalent while the reverse dipping had the lowest mitral E/A ratio. Office systolic blood pressure was the only predictor of left ventricular hypertrophy (OR=1.050, 95% CI=1.004-1.098; p-value = 0.034). Conclusions: The non-dipping pattern was the most prevalent abnormal dipping pattern while the reverse dippers had the highest risk of hypertension-mediated organ damage. Office blood pressure was the only predictor of left ventricular hypertrophy. Hence, office BP measurement as well as ambulatory blood pressure measurements are potentially important tools in risk stratification in resource-poor settings of sub-Saharan Africa.

    Association between Blood Pressure Dipping Patterns and Left Ventricular Hypertrophy among Apparently Healthy Normotensive Nigerians.
    (College of Health Sciences, Ekiti state University, Ado-Ekiti., 2021) Dele-Ojo, B.F; Ogunmodede, James Ayodele; Ojo, O.D
    ackground Abnormal blood pressure dipping pattern has been associated left ventricular hypertrophy among Africans with systemic hypertension. However, more studies are required to show whether abnormal blood pressure (BP) dipping patterns are associated with left ventricular hypertrophy (LVH) in healthy normotensive patients. This study determined the association between BP dipping patterns and left ventricular hypertrophy among normotensive Nigerians. Methods This was a cross-sectional study in which 120 normotensive individuals with no co-morbidities had ambulatory blood pressure monitoring (ABPM) and echocardiography. We defined extreme dippers, normal dippers, non-dippers and reverse dippers as nocturnal systolic BP decline of (≥ 20%), (10% to 19%), (0 to 9%) and (<0%) respectively. Results Fifty-four (45%) were males, the mean age and body mass index were 37.0 ± 10.1years and 24.0 ±4.2 kg/m2 respectively. Sixty-nine (57.5%) were non-dippers and 71 (59.2%) had LVH. Reverse dippers had the highest left ventricular mass index, it was not statistically significant. Binary logistic regression showed age as the only predictor of left ventricular hypertrophy (OR=1.055, 95% CI=1.004-1.109; p-value = 0.033). Conclusions A high prevalence of non-dipping pattern and left ventricular hypertrophy was found among apparently healthy Nigerian normotensives. Increasing age was the only predictor of LVH in our study population. Hence, ABPM and echocardiography are recommended to accurately assess cardiovascular risk in apparently healthy Nigerian normotensives.

    Smartphone Ownership and the Willingness to receive Mobile Health Services among Patients with Hypertension in Nigeria.
    (West African College Of Physicians, 2023) Dele-Ojo, B.F; Ojo, O.D; Omopariola, O.A.; Oseni, T.I.A; Ogunmodede, James Ayodele; Busari, O., Amu, E.O., Adefioye, A.
    BACKGROUND: There are traditional barriers to accessing quality hypertension care in sub-Saharan Africa. Mobile phone technology is increasingly being used to overcome these barriers. This study assessed smartphone ownership and the willingness to receive mobile health services among patients with hypertension in Nigeria. METHODS: Four hundred and twenty-seven (427) patients with hypertension were recruited from two tertiary health institutions in Ekiti State, Nigeria. Questionnaires were fed into the Open Data Kit form, which was used to take data on mobile phone ownership, the willingness to receive and the preferred type of mobile phone-based hypertension health care services. RESULTS: Males were 37.2%. Mean age was 60.6 ± 15.3 years. Of the participants, 48.7% owned smartphones, 21.1% had regular internet subscription on their phones, 94.8% were willing to receive and pay mobile health services. Phone calls (48.0%) and text messages (31.6%) were the most preferred modes of receiving hypertension-related health education. Age category of 45-64 years was the only predictor of willingness to receive mobile health services. CONCLUSION: All our participants owned mobile phones, with 48.7% being smartphones and almost all the participants were willing to receive and pay for mobile health services for prevention, treatment and information on hypertension. Middle age was the only predictor of willingness to receive mobile health, and the most preferred choices were through phone calls and text messages. The above information will guide in the design of favourable mHealth interventions that will be ideal for our study population
