There is a high prevalence of hypertension in Nigeria. Limited knowledge of hypertension, how to prevent it, its outcomes, rapid urbanization, and the adoption of Western eating habits are implicated. Hypertension is an important issue because chronic disease places economic, social, and disease burdens on society. The purpose of this mixed-methods study was to investigate lifestyle practices, knowledge, and attitudes on risks and prevention of hypertension among residents of Ogun State, Nigeria (N = 79). The conceptual framework for this study focused on how knowledge, attitudes, and practices influence the dietary habits, behaviors, and ultimately blood pressure . The PEN-3 model was also used as the theoretical framework for research. The general linear regression model with sums of squares and Pearson's product correlation were used in quantitative analysis of diet, blood pressures, educational attainment, height, physical exercise, and weight to determine the factors that were predictive of hypertension. The main predictors of hypertension were age (p < 0.03), BMI (p <.024), and educational attainment (p < 0.02). Deductive analysis of qualitative data from focus group discussions revealed mothers are a primary source of health knowledge. Also, Babcock University has made a major impact on community health by providing free health lectures. This study contributes to social change by extending the PEN-3 model with two new domains, support for health behavior, and power to change health behavior. This information can be used to help focus government health outreach programs for improved support of individual and community change.
