Key result
Ambulatory blood pressure monitoring showed normotensive women had significantly fewer values ≥140/90 mmHg than hypertensives, with peak pressures occurring in the late afternoon.
Why the study?
Does ambulatory blood pressure monitoring correlate with standard office blood pressure recordings in middle-aged women, and what is their diurnal blood pressure pattern?

Does ambulatory blood pressure monitoring correlate with standard office blood pressure recordings in middle-aged women, and what is their diurnal blood pressure pattern?
Standard office blood pressure diagnosis correlates well with ambulatory monitoring in middle-aged women, who uniquely demonstrate peak blood pressure in the late afternoon rather than the morning.

Office BP diagnosis may align with ABPM in middle-aged women; leaves open whether afternoon peaks require adjusted protocols.
A blood pressure screening was carried out in women aged 40-64 years in a geographically defined area in southern Sweden; the attendance was 72%. Middle-aged women classified as normotensives by standard criteria were found to differ from hypertensives also when blood pressure was recorded with non-invasive ambulatory technique; this was so when calculated for day, night, and 24 hours. The frequency of ambulatory blood pressure values > or = 140/90 mmHg was also significantly lower in normotensives than in hypertensives. The established way of diagnosing hypertension and normotension thus correlated well with the results of ambulatory monitoring in women. Furthermore, women had their highest blood pressure in the late afternoon and not in the mornings, as previously shown in men. This was so in all three groups of women (normotensives, borderline hypertensives, and hypertensives). This difference leaves room for speculation about different types of stress load during the day in men and women.

Enström et al. (1992) conducted a cross-sectional in Hypertension. Ambulatory blood pressure monitoring vs. Standard office blood pressure recording was evaluated on Frequency of ambulatory blood pressure values ≥140/90 mmHg. Ambulatory blood pressure monitoring showed normotensive women had significantly fewer values ≥140/90 mmHg than hypertensives, with peak pressures occurring in the late afternoon.
