Abstract P069: Vegetable Consumption And Hypertension Among 16,445 Africans

Abstract

Background: The association of vegetable consumption with hypertension remains poorly described in sub-Saharan Africa. This study assessed the relationship between vegetable consumption and hypertension among indigenous Africans. Methods: We harmonized data on the frequency of vegetable consumption (servings/week) and hypertension (defined as systolic blood pressure ≥ 140mmHg or diastolic blood pressure ≥ 90mmHg or previous diagnosis or use of antihypertensive medications) from 16,445 participants across five African countries (Ghana, Burkina Faso, Kenya, Nigeria and South Africa) from the SIREN and AWI-Gen studies. Using the recommendation of at least five servings/day (35 servings/week) adapted from the World Health Organization recommendations, and vegetable consumption was classified as 'inadequate' (<35 servings/week) or 'adequate' (≥35 servings/week). The odds ratio (OR) and 95% confidence interval (CI) for hypertension risk was estimated for adequate vegetable consumption using multivariable-adjusted logistic regressions at a two-sided P <0.05. Results: The mean age of participants was 53.0±10.7years, 45.9% (7,552 of 16,445) were males, and 42.9% (7,070 of 16,445) were hypertensives. Adequate vegetable consumption was associated with lower odds of hypertension; OR: 0.86 (95%CI: 0.76, 0.97). The sex-stratified odds was; OR: 0.87 (95%CI: 0.73, 1.02) for females and 0.84 (95%CI: 0.71, 1.00) for males. Conclusion: These findings provide new evidence for promoting regular vegetable consumption in the guidelines for the primary prevention of hypertension among Africans.
