Abstract
This quasi-experimental research study aimed to determine the effects of a lifestyle modification program on blood pressure and resting pulse rate among female older adults with prehypertension living in Na Ngio Sub District, Khao Suan Kwang District, Khon Kaen Province. The subjects were 64 older female adults with pre-hypertension (32 subjects in each group). The lifestyle modification program composed of three mains activities: exercising twice a day (in the morning and the evening), taking low saturated fat, sugar and salt diet, and drilling proper breathing. Blood pressure and heart rate record sheets were used for collecting the data. The resulting data were analyzed using descriptive statistics such as frequency, percentage, and standard deviation. An ANCOVA was used to compare means between the intervention and the control groups. Comparing means in each group used a paired t-test. Results show that systolic blood pressure (SBP) levels significantly decreased more among intervention subjects than among control subjects. Mean difference of SBP levels between intervention and control subjects was 9.72 mmHg (95% CI=7.73-11.71, p<.001). Diastolic blood pressure (DBP) levels also significantly decreased more among intervention subjects than the other subjects in which the difference of DBP level means between the two groups was 8.35 mmHg (95% CI=4.82-11.87, p<.001). Additionally, there was a significant reduction in the resting pulse rate among the intervention subjects less than the other subjects. Means difference of the resting pulse rate between the intervention and control subjects was 8.54 bpm. (95% CI=6.03-11.06, p<.001).
