Prevalence and Determinants of Hypertension Awareness, Treatment, and Control in Botswana: A Nationally Representative Population-Based Survey

Table 3

Distribution of severity of blood pressure elevation among uncontrolled hypertensives (those who are unaware, untreated, and suboptimally treated).

BP measurement	Unaware (N = 637)				Untreated (N = 307)				Suboptimally treated (N = 278)
	%	95%	CI	N	%	95%	CI	N	%	95%	CI	N
Stage1 BP (SBP 140–159)	0.744	0.69	0.791	446	0.56	0.471	0.645	168	0.529	0.444	0.6119	140
Stage2 BP (SBP 160–179)	0.181	0.144	0.225	139	0.253	0.193	0.325	86	0.277	0.214	0.3503	89
Stage3 BP (SBP ≥ 180)	0.075	0.047	0.119	52	0.187	0.121	0.279	53	0.194	0.131	0.2784	49

Unaware hypertensives were those who had elevated BP yet had not previously been informed of a hypertension diagnosis by a health professional. Untreated hypertensives were those who had been previously informed of a hypertension diagnosis but were not on medications in the past 2 weeks and had elevated BP. Suboptimally treated hypertensives were those who had been previously informed of a diagnosis and were on medications yet had elevated BP.
