Abstract

Background: Hypertension, traditionally associated with older populations, is increasingly being diagnosed in young adults. Early onset of elevated blood pressure poses long-term health risks and increases the likelihood of cardiovascular complications. This study aimed to assess the prevalence of hypertension and identify associated risk factors among individuals aged 18–35 years. Materials and Methods: A cross-sectional study was conducted among 500 young adults aged between 18 and 35 years in an urban setting. Participants were recruited through stratified random sampling from colleges and workplaces. Blood pressure was measured using a calibrated sphygmomanometer following standard guidelines. Demographic data, lifestyle habits, and family history were collected using a structured questionnaire. Hypertension was classified according to the American Heart Association criteria. Statistical analysis was performed using SPSS version 26.0, with logistic regression to identify significant predictors. Results: The prevalence of hypertension among the participants was 18.4% (n=92), with a higher proportion in males (22.1%) than females (14.5%). Key risk factors significantly associated with hypertension included obesity (OR=2.9, p<0.01), family history of hypertension (OR=2.4, p=0.03), sedentary lifestyle (OR=1.8, p=0.04), and high salt intake (OR=2.1, p=0.02). Smoking and alcohol consumption also showed a positive correlation but did not reach statistical significance (p>0.05). Conclusion: The findings indicate a concerning prevalence of hypertension in young adults, with modifiable lifestyle and dietary factors playing a crucial role. Early identification and preventive strategies targeting this age group are essential to reduce future cardiovascular disease burden.

INTRODUCTION

Hypertension is a leading modifiable risk factor for cardiovascular morbidity and mortality worldwide, contributing significantly to the global burden of non-communicable diseases (1). Traditionally regarded as a condition of older adults, recent epidemiological trends suggest an alarming rise in the incidence of elevated blood pressure among younger populations, particularly those aged 18 to 35 years (2,3). The early onset of hypertension is especially concerning due to its prolonged exposure period, which increases the lifetime risk of end-organ damage and cardiovascular events such as myocardial infarction and stroke (4).

Multiple factors contribute to the development of hypertension in young adults, including genetic predisposition, dietary habits, sedentary lifestyles, psychosocial stress, and the increasing prevalence of obesity (5,6). Despite growing awareness, hypertension in this age group often remains underdiagnosed and poorly managed due to low screening rates and limited perception of personal risk (7). Moreover, asymptomatic presentation in the early stages further delays diagnosis and intervention (8).

 

Understanding the current prevalence and associated risk factors of hypertension among young adults is essential for designing effective preventive strategies. However, most existing literature is focused on middle-aged or elderly populations, with relatively fewer studies targeting the younger demographic (9). This study aims to determine the prevalence of hypertension among young adults in an urban setting and identify the key behavioral and clinical factors contributing to its development.

MATERIALS AND METHODS

A total of 500 individuals were selected using stratified random sampling from colleges, workplaces, and community centers. Participants who had known cardiovascular diseases, were on antihypertensive medication, or declined consent were excluded.

 

Data collection was done using a pre-validated, structured questionnaire that included sociodemographic information, lifestyle habits (such as smoking, alcohol use, physical activity), dietary patterns (especially salt intake), and family history of hypertension.

 

Blood pressure was measured using a standardized digital sphygmomanometer after the participant had rested for at least five minutes. Two readings were taken five minutes apart in a seated position, and the average was considered. Hypertension was defined as systolic blood pressure ≥130 mmHg and/or diastolic blood pressure ≥80 mmHg, in accordance with the American College of Cardiology/American Heart Association guidelines (1).

 

Anthropometric measurements including height and weight were recorded using calibrated instruments. Body Mass Index (BMI) was calculated and classified based on WHO guidelines. Physical activity was assessed using the Global Physical Activity Questionnaire (GPAQ).

 

Data were entered and analyzed using SPSS version 26.0. Descriptive statistics were used to summarize the baseline characteristics. The prevalence of hypertension was reported as percentages. Chi-square test and binary logistic regression were employed to identify associations between hypertension and potential risk factors. A p-value of <0.05 was considered statistically significant.

RESULTS

A total of 500 young adults participated in the study, comprising 280 males (56%) and 220 females (44%), with a mean age of 26.4 ± 4.8 years. The overall prevalence of hypertension was found to be 18.4% (n=92). Among these, stage 1 hypertension was identified in 67 participants (13.4%) and stage 2 hypertension in 25 participants (5.0%).

Table 1 presents the demographic distribution of the study population and the prevalence of hypertension according to gender, BMI, and lifestyle variables. The prevalence was significantly higher in males (22.1%) compared to females (14.1%) (p = 0.03).

In summary, the study identified a notable prevalence of hypertension among young adults, with modifiable lifestyle factors playing a prominent role in its development (Tables 1 and 2).

DISCUSSION

This cross-sectional study revealed that approximately 18.4% of young adults aged 18–35 years were hypertensive, aligning with recent findings that suggest hypertension is no longer confined to older populations (1,2). Our results underscore a growing public health concern, particularly as early-onset hypertension is strongly associated with a higher lifetime risk of cardiovascular disease and target organ damage (3,4).

 

Male participants exhibited a significantly higher prevalence of hypertension compared to females, consistent with earlier studies attributing this disparity to hormonal, behavioral, and lifestyle factors such as smoking, alcohol intake, and reduced healthcare engagement among men (5,6). Obesity emerged as a key independent predictor, with overweight individuals nearly three times more likely to be hypertensive. This finding echo previous research highlighting the strong link between elevated BMI and increased vascular resistance and sympathetic nervous system activation (7,8).

 

Our study also identified high dietary salt intake and sedentary lifestyle as significant modifiable risk factors. Participants consuming more than 5 grams of salt daily had a more than threefold increase in hypertension risk, which concurs with WHO recommendations and previous epidemiological data from both Western and Asian cohorts (9,10). Similarly, physical inactivity doubled the odds of developing hypertension, consistent with literature affirming the benefits of regular aerobic exercise in maintaining normotensive states (11,12).

 

Family history was another important determinant, reinforcing the genetic and familial aggregation of blood pressure traits (13). This emphasizes the need for targeted screening in individuals with a positive family history, even in the absence of symptoms.

 

Interestingly, while smoking and alcohol use were more prevalent in the hypertensive group, they did not achieve statistical significance in multivariate analysis. This may be due to underreporting, smaller sample sizes for these subgroups, or confounding factors. However, both have been implicated in endothelial dysfunction and long-term cardiovascular risk in several large-scale studies (14,15).

 

The cross-sectional design of our study limits the ability to establish causality, and recall bias cannot be entirely excluded due to the use of self-reported questionnaires. Nevertheless, the sample size and methodological rigor strengthen the internal validity of our findings.

 

In light of the observed trends, there is a pressing need for early intervention strategies focusing on lifestyle modification, regular blood pressure screening, and awareness programs tailored for the younger population. Future longitudinal studies could help establish causal pathways and evaluate the effectiveness of preventive strategies initiated in early adulthood.

CONCLUSION

This study highlights a significant prevalence of hypertension among young adults, with key risk factors including male gender, obesity, high salt intake, sedentary lifestyle, and family history. These findings emphasize the need for early screening and targeted lifestyle interventions to prevent long-term cardiovascular complications in this age group.
