Author	Sample size	Area	Main findings
Singh et al., 2017 [22]	640	Varanasi	About a third of the participants had high blood pressure, while half were at risk for developing hypertension. Low levels of education, care, and regulation of hypertension were also prevalent.
AlWabel et al., 2018 [23]	130	Saudi Arabia	Gender, BMI, and previous diagnoses of diabetes and hypertension were shown to be significantly linked. Their findings provide credence to the widely held belief that young individuals have a disproportionately high prevalence of prehypertension and hypertension, the vast majority of whom remain untreated.
Hu et al., 2017 [24]	15,296	China	There is a widespread pandemic of prehypertension and hypertension in southern China. More research is required to identify an indicator that correctly represents visceral fat and is closely related to cardiovascular disease.
Ondimu et al., 2019 [25]	160	Kenya	Individuals with a BMI of 25 or below were 3.05 times more likely to be hypertensive (95% CI: 1.26, 7.40; p=0.014). The risks of developing hypertension almost tripled if you had a blood pressure-raising relative (OR: 2.78, 95% CI: 1.20, 6.46; p=0.018). The risk of developing hypertension was cut by almost 70% in those who gave up alcohol.
Liu et al., 2017 [26]	4,120	China	Findings showed that hypertension rates among local youth increased between 2011 and 2014. Hypertension is most common in men aged 40 and over, those with lower socioeconomic status who work in rural regions, those who are overweight or obese, and those who smoke cigarettes.
Paul et al., 2020 [27]	322	Bangladesh	The main modifiable risk factors of hypertension in young people (18-44 years)include tobacco use, obesity, dyslipidemia, and excessive salt consumption. These variables, together with antihypertensive drugs, are essential for the prevention and treatment of hypertension.
Amanyire et al., 2019 [28]	156	Uganda	The BSU faculty and staff are not immune to the dangers of hypertension, diabetes, and obesity, but there is a lack of information about their causes, symptoms, and how to avoid them. Public health measures for the university workers include regular exercise, regular checkups, and a regulated diet.
Tymejczyk et al., 2019 [29]	61,000	Haiti	The rates of hypertension, obesity, and unmet healthcare requirements were all quite high across all age groups. The advantages of more cost-effective preventive and treatment programs should be extended to slum inhabitants; therefore, a deeper understanding of the links between intraurban migration and environmental risk factors for hypertension is necessary.
Mouhtadi et al., 2018 [30]	1,362	Lebanon	Although hypertension is common among adults in Lebanon due to a number of factors, these causes are often not fully appreciated, resulting in inadequate management of the condition. Young adult men (aged 18-29) had the highest prevalence of hypertension. These results highlight the urgent need for better hypertension identification, treatment, and management among adult populations in Lebanon.
Bui Van et al., 2020 [31]	319	Vietnam	High hypertension prevalence was found in two Chiem Hoa District communes in Tuyen Quang province. Overall hypertension and isolated systolic hypertension risk variables were age, BMI, waist-to-hip ratio, and inactivity. The effects of ethnicity on isolated systolic hypertension were particularly notable.
