BP blood pressure, CI Confidence interval, F Female, M Male, SBP systolic blood pressure, DBP diastolic blood pressure

*p <0.05 ** p ≤ 0.01; *** p ≤ 0.001: significant difference between genders. For the age groups and the midlife age categories, p-values were calculated based on chi-square tests assessing the significance of differences in sample proportion. For the total sample, p-values were presented either as reported in the original publications [21, 24, 26–32, 34–37], or calculated based on chi-square tests [23, 25, 39]

^aNationally representative studies

^bThe age groups that were selected for each study in order to generate midlife prevalence of hypertension are highlighted in bold.

^cPrevalence of midlife hypertension by gender was compiled by selecting the age groups falling between 35 to 65 years in the original publications

^dHypertension was assessed by actual BP measurements [26, 27, 39], or by either BP measurements or self-report of previous diagnosis [21, 24, 29, 31, 32, 34–37]. For BP measurements, hypertension was identified when SBP > =140 and/or DBP > =90 mmHg for all studies except for Khader et al., 2007 [24] and Bouguerra et al., 2006 [36], where the cut-offs used were SBP > =130 and/or DBP > =85 mmHg

^eSignificance between genders and 95% confidence intervals could not be calculated due to insufficient data [25, 31, 35]

^fThe significant difference between genders for the total sample, reported from the original publications, was adjusted in three studies [29, 31, 34]

^gPrevalence of midlife hypertension could not be determined due to overlapping age ranges [24], or insufficient data to generate pooled prevalence [35]
