ABSTRACT
Introduction@#Hypertension in adult Filipinos is a significant concern for its increasing number (overall prevalence: 22.3). Percentage of thyroid function abnormalities is 8.53% with the greatest proportion of volunteers having subclinical thyroid disease. To our knowledge, there is no available Filipinobased study on hypertension and subclinical hyperthyroidism. The study aims to determine the prevalence of subclinical hyperthyroidism in adults with hypertension. It also aims to determine the difference among age groups and gender with subclinical hyperthyroidism and hypertension. @*Methods@#This was a prospective cross-sectional prevalence study. Minimum sample size was computed at 80 but total sample taken was 98. Study population was taken from January 2019 to May 2019. All hypertensive patients with thyroid function test done in a nuclear medicine section in a tertiary institution were included. This study utilized prevalence rate. To determine the difference between age groups of patients with subclinical hyperthyroidism and hypertension, age groups were treated as follows: late adolescence (18–24), early adulthood (25–34), middle adulthood (35–60), late adulthood (61–75), very old age (76+). Significant difference of prevalence rate for each age group and gender was determined using analysis of variance and t-test respectively. @*Results@#The over-all prevalence of subclinical hyperthyroidism in hypertensive patients is 13.13% with most prevalence on late adolescence and male population (25% and 17.65% respectively). @*Conclusion@#An increase in vigilance with thyroid disorders, especially subclinical hyperthyroidism might be warranted more in males in 18 to 24 years of age. An updated Filipino-based, or a larger Asian-based guideline which will encompass a larger population is needed, due to an increase in migration in this region. This Asian-based guideline will benefit healthcare standards in hypertensives in this region.
