The variables studied included UPF consumption habits with modified Food Frequency Questionnaire, waist circumference with metlin, and blood pressure with digital tensimeter.The sample was 71 respondents using purposive sampling technique, Data analysis was performed univariate analysis using frequency distribution and bivariate with Chi-Square test (α = 5%).Results: The results showed 49,3% of respondents often consumed UPF, the waist circumference measurement results showed 74,6% of respondents were obese, and 67,6% of respondents had abnormal blood pressure. Statistical tests show there is no relationship between UPF consumption habits and blood pressure (p-value = 0,063. There is a relationship between waist circumference and blood pressure with a risk of 3,8 times greater than respondents who have a normal waist circumference size (p-value = 0,015; OR = 3,846).Conclusion: Waist circumference is related to adult blood pressure while UPF consumption habits are not related to increased adult blood pressure at Kedungmundu Health Centre.]]>
