Indeks massa tubuh dan aktivitas fisik dengan tekanan darah pada pelajar SMA
Abstract: A trend towards in increase of hypertension
in adults and children. If criteria of hypertension according to JNC VII 2003
applied to the population aged 15-17 years in Indonesia, the prevalence of
hypertension in adolescents was obtained 5.3% nationally. Examination of blood
pressure and factors related to blood pressure are of particular importance in
children due to the decline in physical activity and weight changes
contributing to blood pressure elevations that occur at this point in
maturation. Blood pressure levels begin to increase as children approach
adolescence. Weight control and physical activity regularly are recommended to
prevent blood pressure elevations in both adult and youth.
Objective: Determine the relationship between body mass index and
physical activity with blood pressure in high school students in Pekanbaru.
Method: This is an analytic observational study with cross sectional
design. This study was involved 353 high school students in Pekanbaru who meets
inclusion and exclusion criteria through cluster sampling technique. Data
collected by direct measurements such as weight, height and blood pressure
whereas physical activity and characteristic of the subject was collected by
questionnaire. The results of the data collection were analyzed using
univariate, bivariate and multivariate analysis.
Results: There is a correlation between body mass index with systolic
(p=0.000; r=0.238) and diastolic blood pressure (p=0.010; r=0.136). Each
increase in 1 kg/m2 body mass index was linked with an increase of 2.339 mmHg
systolic blood pressure and 0.979 mmHg diastolic blood pressure. However, there
is no correlation between physical activity with systolic (p=0.829) nor
diastolic blood pressure (p=0,643). Multivariate analysis showed that sex and
screen time activity were factors most dominantly affecting blood pressure.
Conclusion: There is a correlation between body mass index with blood
pressure. However, there is no correlation between physical activity with blood
pressure.
