Gaps in secondary prevention among stroke survivors in rural Gadchiroli, India: a community-based cross-sectional study

Background: With epidemiological transition, stroke has emerged
as a public health priority in rural India. However, population-level information
on secondary prevention of stroke from rural areas of India and other low- and
middle-income countries remains exceedingly rare.

Methods: In a cross-sectional community-based survey, trained surveyors
screened a well-defined population of 74,095 individuals living in 64 villages
in Gadchiroli district of India for symptoms of stroke. A trained physician
evaluated screen positive patients, diagnosed stroke, measured blood pressure
and collected information on prior diagnosis of risk factors and current use of
medications using a structured questionnaire.

Results: A total of 265 stroke survivors were identified. Prior diagnosis of hypertension
was made in 57.4%, diabetes in 9.8%, hyperlipidaemia in 0.4%, ischaemic heart
disease in 1.5%. and atrial fibrillation in 1.1%. Blood pressure was
uncontrolled (>140/90) in 46% of stroke survivors. Among men 71.2% used
tobacco and 30% used alcohol, while among women 38.2% used tobacco and none
used alcohol. Only 40.8% of stroke survivors were receiving antihypertensive medications,
while 10.6% were on antiplatelet agents and 4.9% were on statins. In a
multivariate analysis, age <50 years (OR 0.2, 95% CI 0.1-0.5), male sex (OR 0.2,
95% CI 0.2-0.8) and lower economic status (no assets vs four assets; OR 0.3,
95% CI 0.1-0.9) were associated with lower odds of receiving medications for
secondary prevention of stroke.

Conclusions: There were significant gaps in secondary prevention
of stroke in rural Gadchiroli. Healthcare programmes for secondary prevention
of stroke in rural areas will have to ensure that blood pressure is adequately
controlled, alcohol and tobacco cessation is promoted and special attention is
paid to those who are younger, men and economically weaker.
