Beliefs about hypertension among Nigerian immigrants to the United Kingdom: A qualitative study

OBJECTIVE: The aim of the study was to elicit beliefs about hypertension among Nigerian immigrants in the United Kingdom. BACKGROUND: The distributions of cardiovascular risk factors and diseases are not shared equally across ethnic and economic groups in the United Kingdom. Its burden is more clustered among minority ethnic populations and migrant groups including black African Nigerian migrants. Similar patterns have been reported across Europe, Australia, Canada, Nordic countries and the United States of America. There are about 300 distinct ethnic groups in Nigeria and reliable information about their beliefs about hypertension is not available. Given that the United Kingdom has a large community of Nigerian immigrants from these different ethno-cultural backgrounds, understanding their unique beliefs about hypertension may help promote appropriate care for this population in the United Kingdom and Nigeria. SETTING: A single Pentecostal church community in West London PARTICIPANTS: Twenty-seven Nigerian migrant members of the church entered and completed the study METHODS AND OUTCOME MEASURE: A qualitative interview study was conducted. The interviews were analysed using thematic framework analysis. The outcome measures were emerging themes from the thematic framework analysis. RESULTS: Participants expressed beliefs in four major areas related to hypertension: (1) The Meaning of the term hypertension, (2) Perceptions of causation, (3) Effects of hypertension, and (4) Perceptions of treatment. The study revealed a diversity of beliefs about hypertension which incorporated both orthodox and culturally framed ideas. CONCLUSIONS: This study identified important beliefs among Nigerian migrants about hypertension that can contribute to our understanding of the management of hypertension in this group and suggests the need for further research to determine whether these beliefs may be representative of this group.
