Abstract
We selected most informative risk factors of stroke as well as established the association
with stroke and derived a risk score of stroke using statistically acceptable
modi cations. Secondary data on the aging population of Ghana was used with
a sample size of 5119. The LASSO Logistic Regression was implemented through
\R"statistical software for windows version.3.1.1 using the penalised package. A
key risk factor identi ed was hypertension. A person who exercises regularly had
a low risk of developing stroke as compared to one who did not exercise. Data
about stroke discovered angina and arthritis as emerging risk factors of stroke
in addition to hypertension, physical activities, age and diabetes. We hypothesise
that hypertension, diabetes and lack of physical activities re
ect the trend of
stroke cases in Ghana. There must be public consciousness about the signi cance
of managing hypertension in Ghana.
