Résumé
Background: Body temperature is an indicator of health status. However, thermoregulatory function is thought to decline with aging. Objectives: To determine normal body temperature and the effects of age, sex, ambient temperature (AT), and body mass index (BMI) on normal oral temperatures (OTs). Design: A prospective four group comparative descriptive design was used to compare four cohorts: young adults in summer, older adults in summer, young adults in winter, and older adults in winter. Methods: The OT of 519 community dwelling older adults ages 65-95 and 540 younger adults ages 20-64 was compared. The OT was taken with an electronic thermometer between 8 a.m. and 10 a.m. during summer and winter in 2007 in Taipei, Taiwan. Results: There was no difference in mean OT between the <65 and >65 groups measured during winter. However, the mean OT of the <65 group was 0.11 °C lower than the >65 group measured in the summer. Subjects (>85 years) had a higher correlation coefficient (r = 0.48) between OTand AT than those in the 65-74 year older group (r = 0.31) and 75-84 year older group (r= 0.23). Moreover this study found that the mean OT of older females was higher than that of older males in both winter and summer cohorts. Finally, multiple regression analysis results indicated AT and sex were predictors of OT while age and BMI were not a significant predictor ofOT. These four factors together accounted for 9.4% of the variance in the overall sample (age 20-95), 12.8%, in thos
