Influência de diuréticos em aspectos salivares de pessoas idosas hipertensas

Abstract

Diuretics, widely used by elderly people, aim to control systemic blood pressure (SBP), and may have adverse effects on the quantity and composition of body fluids. The objective of this study was to analyze salivary aspects in hypertensive elderly people who use diuretics, compare them with those who do not use them, as well as identify associated factors. This is a cross-sectional study. Through a questionnaire, the following were collected: sociodemographic data, general health status, medication use, edentulism, use of prosthesis and xerostomia. Stimulated salivary flow, hydrogen potential (pH), salivary economic capacity (TC) were impaired with colorimetric strips. The sample consisted of 160 elderly people with systemic arterial hypertension (SAH). To analyze the data, the chi-square, Mann Whitney, Kruskal-Wallis and Spearman Correlation tests were performed at a confidence level of 95%. The use of diuretics was statistically associated with female gender (p<0.0001), low level of education (illiteracy and primary education) (p=0.029), multimorbidities (p=0.002), DM (p=0.049) and osteoporosis ( p=0.026). There was no significant difference in the salivary aspects of elderly people who used diuretics, compared to those who did not use them. There was a significant reduction in FS in elderly people with arthritis (p=0.045). Lower pH values were found in females (p=0.043) and edentulous people (p=0.001), while a lower salivary CT was found in females (p=0.042), overweight (p=0.005) and edentulous people ( p=0.01). There was a significant association of xerostomia with multimorbidity (p=0.008), DM (p=0.049) and polypharmacy (p=0.008). The use of diuretics does not interfere with trained salivary aspects, which are influenced by morbidities, female sex, edentulism, overweight and polypharmacy.
