High blood pressure and diabetes are known risk factors for stroke, but now a new study suggests that the risk may decrease as people age, researchers report online in Neurology. Medical Journal of the American Academy of Neurology.

,High blood pressure and diabetes are two important risk factors for stroke that can be controlled with medication, thereby reducing a person’s risk.recalls the author of the study george howardfrom the School of Public Health, University of Alabama (USA).

,Our findings suggest that its association with stroke risk may be significantly reduced in older age, although other risk factors do not change with age –highlight, These differences in risk factors mean that determining whether a person is at high risk of stroke may differ depending on their age.,

The study included 28,235 people who had never had a stroke. In this group, 41% were black and 59% were white. The participants were followed for an average of 11 years.


At the start of the study, participants were interviewed and physically examined to assess risk factors. Risk factors include high blood pressure, diabetes, smoking, atrial fibrillation, heart disease, and left ventricular hypertrophy, which is thickening of the left ventricle of the heart. Howard adds that because of the known increased risk of stroke in the black population, race was also taken into account as part of the risk factors assessed.

The researchers confirmed stroke by reviewing medical records with the participants every six months. During the study, 1,405 strokes occurred in 276,074 person-years. Person-years represent both the number of people participating in the study and the length of time each person was in the study.

The participants were divided into three age groups, which were compared. The age ranges of those groups varied slightly, depending on the data analyzed by the researchers. In general, the youngest group included participants between the ages of 45 and 69, the middle group those between 60 and 70, and the oldest group those 74 and older.

researchers discovered that People with diabetes in the youngest age group were twice as likely to have a stroke as people of the same age who did not have diabetesWhereas older people with diabetes had a nearly 30% higher risk of stroke compared to people of the same age who did not have diabetes.

They also found that people with high blood pressure in the younger age group had an 80% higher risk of stroke than people of the same age without high blood pressure, while the risk was reduced by 50% for those with high blood pressure. People of similar age without high blood pressure.

Furthermore, when the researchers examined race as a risk factor, they found a higher risk of stroke among younger black participants compared with white participants in that group. The racial gap narrowed in the older age group. For stroke risk factors, such as smoking, atrial fibrillation, and left ventricular hypertrophy, the investigators found no age-related change in risk.

,It is important to note that our results do not suggest that treatment of hypertension and diabetes is no longer important in older age groups. –needs Howard–. These treatments are still very important to a person’s health, but it may also be prudent for doctors to focus on managing risk factors as people age, such as atrial fibrillation, smoking, and left ventricular hypertrophy.,

Howard also points out that even when the effect of risk factors diminishes with age, the overall number of people who suffer a stroke may be higher at older ages, because the overall risk of stroke increases with age. For example, in the lowest age group for high blood pressure, researchers estimated that about 2.0% of people with normal blood pressure suffered a stroke, compared with 3.6% of those with high blood pressure. In the older age group, about 6.2% of people with normal blood pressure had a stroke, compared to 9.3% of people with high blood pressure.
