A recent global study has found a significant increase in stroke cases among younger adults, with a 36% rise in cases among people aged 15 to 49 between 1990 and 2021. According to research published in the Journal of the American Heart Association, this trend is a growing concern, as stroke is often associated with old age. The study examined stroke trends in 204 countries and territories, highlighting the need to address conditions and lifestyle factors that increase the risk of stroke at a younger age.
High blood pressure, also known as hypertension, is a major risk factor for stroke, particularly among younger adults. It occurs when the force of blood against artery walls remains consistently high, potentially damaging blood vessels over time. If left uncontrolled, hypertension can cause blood vessels in the brain to become damaged or rupture, leading to a stroke. A 2025 global analysis identified high systolic blood pressure as the leading contributor to stroke-related disability among young adults in Ghana.
The increasing prevalence of obesity and excess body weight is another significant risk factor for stroke among younger adults. Excess body weight can increase the risk of several conditions associated with stroke, including high blood pressure, diabetes, and unhealthy cholesterol levels. As younger adults in Ghana adopt increasingly sedentary lifestyles and diets high in calories, salt, and unhealthy fats, their risk of developing these conditions may increase.
Diabetes and high blood sugar are also important risk factors for stroke. When blood sugar levels remain high over time, they can damage blood vessels and contribute to cardiovascular complications. People with diabetes are also more likely to have high blood pressure, which further increases their risk. The concern is that type 2 diabetes is increasingly being diagnosed in younger populations in Ghana, exposing them to potential complications earlier in life.
Smoking and tobacco use are significant contributors to stroke risk, particularly among younger adults. Tobacco damages blood vessels and increases the likelihood of blood clots forming. Nicotine can raise blood pressure, while other chemicals in cigarette smoke damage the lining of blood vessels and reduce the amount of oxygen carried in the blood. The World Health Organization identifies tobacco use as one of the major modifiable contributors to stroke.
Other lifestyle factors, such as physical inactivity, unhealthy eating habits, and excessive alcohol consumption, also contribute to the risk of stroke among younger adults in Ghana. A lack of regular exercise increases the likelihood of developing obesity, high blood pressure, diabetes, and unhealthy cholesterol levels. Diets containing excessive salt, saturated fats, and processed foods can contribute to high blood pressure, obesity, and unhealthy cholesterol levels.
Recognising stroke symptoms early and managing underlying health conditions can help reduce the risk of stroke among younger adults. It is essential for individuals to be aware of the risk factors and take proactive steps to maintain a healthy lifestyle, including regular exercise, a balanced diet, and stress management. By addressing these modifiable risk factors, Ghana can reduce the burden of stroke among younger adults and promote overall cardiovascular health.
Key points
- High blood pressure, obesity, and diabetes are primary risk factors for stroke among younger adults.
- Lifestyle factors, such as physical inactivity, unhealthy eating habits, and excessive alcohol consumption, contribute to stroke risk.
- Recognising stroke symptoms early and managing underlying health conditions can help reduce the risk of stroke.
