Background: Sustained control of blood pressure, is dependent on degree of self-management, which includes self-inte- gration, self-regulation, self-monitoring and adherence to regimen. We assessed the pattern of self-management of hyper- tension among adult hypertensive patients in a developing country. Methods: Cross-sectional study design and convenience sampling, was used to recruit adult hypertensive patients, attending Lagos State University Teaching Hospital, Lagos, Nigeria. Interviewer-administered questionnaire was used to obtain data on self-management components. SPSS version 21.0 was used to analyze data, with p-value set at 0.05. Result: One hundred and seven (107) respondents, had mean age of 49.0 ± 12.0 years. Mean value for self-management was 3.15 ± 0.55, comprising self-integration (3.06 ± 0.36), self-regulation (3.32 ± 0.63), self-monitoring (3.29 ± 0.84) and adherence to regimen (3.15 ± 0.55). Most components of self-management, had high levels of mean score. Respondents that were less than 40 years, compared with those that were more than 40 years, had greater mean values for self-integration (3.37 vs 3.05), but significantly lesser values for all other components (p < 0.05). Conclusion: Young hypertensives had poor levels of most components of self-management. There is urgent need for health educational programs on self-management of hypertension among young people in sub-Saharan Africa.
