Abstract

This study was performed to evaluate the differences in blood pressure, sodium intake and dietary behavior changes according to the extent of session attendance on sodium reduction education program for pre-hypertensive adults in a public health center. Sodium reduction education program consisted of 8 sessions for 8 weeks. Fifty three patients who completed the pre and post nutritional assessments were classified into 2 groups according to the session attendance rate. Nineteen participants who attended the education program 3 times or less (${\leq}3$) were categorized into the less attendance (LA) group and 34 participants attended 4 times or more (${\geq}4$) into the more attendance (MA) group. Blood pressure, anthropometric measurements, serum lipid profile, nutrient intakes including sodium, nutrition knowledge and dietary behavior score were assessed before and after the nutrition education program. Mean sodium intakes (p<0.001), systolic/diastolic blood pressure (p<0.001), and weight (p<0.001) were significantly decreased in the MA group after sodium reduction education program. Compared to the MA group, mean sodium intakes, systolic/diastolic blood pressure were not significantly changed after the education program even with significantly increased nutrition knowledge (p<0.05) and dietary behavior score (p<0.01) in the LA group. It appears that pre-hypertensive adults need to attend the sodium reduction education program for at least 4 times or more to gain beneficial effects from the intervention. Positive feedback of healthcare team or offering more cooking classes may be needed to raise the attendance rate in the sodium reduction education program.
