RESUMO
Elevated blood pressure (BP) is the leading cause of global mortality, but control rates remain poor because most patients, especially in Africa, are unaware. May Measurement Month (MMM) is an annual global BP screening campaign that was initiated by the International Society of Hypertension (ISH) in 2017 to raise awareness of raised BP. Following participation in 2017 and 2018, Kenya participated again in 2019 and the results are reported here. Screening was carried out in 30 sites by volunteers coordinated by the Kenya Cardiac Society. Participants had three BP readings by standard methods with the last two being averaged and recorded. Heart rate, weight, height, socio-demographic parameters, and co-morbidities were documented. Hypertension was defined as a systolic BP (SBP) ≥140 mmHg and/or a diastolic BP (DBP) ≥90 mmHg or being on treatment with at least one antihypertensive medication. A total of 33 992 participants were screened, mean age was 42.5 (SD 16.8) years and 58.7% of participants were female. Only 27.3% had their BPs checked within the preceding 12 months. After multiple imputation, 26.1% were hypertensive, of whom 34.5% were aware of their hypertension and 31.5% were on treatment. Of those on treatment, 59.7% were controlled translating to 18.8% of all hypertensives. Being on treatment for hypertension, overweight, obese or having had hypertension in previous pregnancy were associated with increased SBP and DBP, while diabetes was associated with raised SBP. Two-thirds of hypertensives were unaware. Only a third of those aware were on treatment, with about 60% of these controlled. Lack of awareness remains a significant barrier to BP control. Programmes to raise awareness such as MMM are significant in raising population awareness.
RESUMO
Hypertension (HTN) is highly prevalent and the leading cardiovascular risk factor for death globally. A large proportion of individuals with high blood pressure (BP) are unaware leading to under treatment and poor control. To address this, the International Society of Hypertension (ISH) initiated a global mass screening campaign, the May Measurement Month 2017 (MMM17), in which Kenya participated. Following the success of the campaign, its successor MMM18 was launched. Here, we present the Kenyan results for MMM18. Opportunistic screening of consenting adults was done in various sites across Kenya in May 2018, by volunteers trained using ISH material, under the co-ordination of the Kenya Cardiac Society. Blood pressure, pulse rate, weight, and height were measured by standard methods. Definitions of HTN and statistical methods all adhered to the standard MMM protocol. We screened 49 548 subjects, mean age 39.95 (15.3) years. In total, 49.4% had never had a BP measurement taken. After multiple imputation, 17.1% were hypertensive and of those who were hypertensive, 30.7% were aware, 26.6% were on antihypertensive treatment, and 13.0% had controlled BP. Alcohol use, excess weight, and treatment for HTN were associated with higher BP. The Kenyan MMM18 sites successfully screened more than three times the number screened in 2017, hence improving public awareness. Less than half the population had ever had a BP check. Less than a third of the hypertensives were aware with correspondingly poor treatment and control rates. Opportunistic mass screening is useful in raising public awareness.
RESUMO
BACKGROUND: Vitamin D deficiency is a common condition that affects approximately 30-50% of the worldwide population. Vitamin D deficiency is associated with an increased risk of cardiometabolic diseases and is considered a cardiovascular risk factor globally. Methods: This is a retrospective cross-sectional study that aimed to identify the prevalence of vitamin D deficiency and its associations with the cardiovascular disease (CVD) risk profile of patients presenting for cardiac evaluation at Primecare Heart Clinic, a private heart clinic in Nairobi, Kenya, between January 1, 2020 and January 31, 2022. RESULTS: Females with vitamin D deficiency composed 58.87% of the study participants. The average 10-year Framingham CVD risk level of the vitamin D-deficient participants was 7.09%. Participants with vitamin D deficiency that were older and had low serum high-density lipoprotein C (HDL-C) levels and high systolic blood pressure (BP) had a higher risk of CVDs. Male participants were at five times higher risk of CVDs. Vitamin D-deficient patients who were older and had a low HDL cholesterol level and high systolic BP are at a high risk of CVDs. The two-way analysis of variance (ANOVA) test value was 345.6992, and the p-value was 0.002884. CONCLUSION: Our study demonstrated that a low level of vitamin D was associated with a higher Framingham cardiovascular risk score and cardiovascular risk in patients. Nonetheless, this is a retrospective study, which is a major limitation of this study.
