Relationship between Body Mass Index and Waist Circumference with Isolated Systolic Hypertension in the Elderly
Keywords:body mass index (BMI), waist circumference, isolated systolic hypertension (ISH), elderly
Globally, it is estimated that 15% of the elderly had isolated systolic hypertension (ISH). ISH in the
elderly may occur because of the aging process or other risk factors, such as obesity. Obesity is
divided into total obesity which is measured by body mass index (BMI), and abdominal obesity
which is measured by waist circumference (WC). The difference in these measurement parameters
made this study aim to determine the relationship between BMI and WC with the incidence of ISH in
The study was an analytical observational cross-sectional method and used a consecutive sampling
technique with the samples aged ≥ 60 years old that had ISH. The research measured blood
pressure, weight, height, and waist circumference. The data was analyzed by Rank Spearman test
for the relationship between BMI with the incidence of ISH and Chi-Square test for the relationship
between waist circumference with the incidence of ISH, with α values for both tests being 0,05.
The samples in this study were 110 elderlies with the most criteria being young elderlies (60%),
female gender (67,3%), work as farm worker/farmer (41,8%), ISH grade I (66,4%), obesity (36,4%), and
abdominal obesity (54,5%). There was no relationship between BMI with the incidence of ISH in the
elderly (p= 0,827) but had a relationship between waist circumference with the incidence of ISH in
the elderly (p= 0,001).
BMI as an indicator of total obesity is not associated with the incidence of ISH in the elderly, but
waist circumference as an indicator of abdominal obesity shows a relationship with the incidence of
ISH in the elderly.
