Hubungan Indeks Massa Tubuh dengan Tekanan Darah pada Lansia di Posyandu Lansia Dataran Tinggi Binjai Timur

Abstract

An increased number of elderly in Indonesia has an impact on an increase in

health problems due to the aging process. This condition triggers the development

of non-contagious diseases, one of which is high blood pressure (hypertension).

The increase in blood pressure can be affected by numerous factors, such as

excess body weight/obesity. Excess weight is assessed using the body mass index,

which is an indicator to measure nutritional status related to overweight and

underweight. A high body mass index indicates the possibility of an increase in

blood pressure. This study aims to determine the correlation between body mass

index and blood pressure of the elderly at the Integrated Health Post (Posyandu)

of Dataran Tinggi, East Binjai. This is a quantitative Cross Sectional research

design with an analytic observational research type that is carried out in October

2022. The samples employ 39 elderly as the respondents which are taken by the

Accidental Sampling sample technique based on the presence of elderly at

Posyandu. This study uses the Pearson statistical test to show that the results of

the analysis show that the majority of respondents (43.6%) have the category of a

normal body mass index and the category of systolic blood pressure in

hypertension II (59.0%). The results of the correlation analysis (p>0.05) show

that there is no significant correlation between body mass index and blood

pressure of systolic (r=-0.015; p=0.928) and diastolic (r=-0.258; p=0.133).
