OBJECTIVE: To determine whether there is an association between hypotension and incident cases of idiopathic chronic fatigue. DESIGN: A prospective study. SETTING: Johns Hopkins Precursors Study. PARTICIPANTS: Medical students (n = 876) in graduating classes from 1948 to 1964. MAIN OUTCOME MEASURE: 'Easy fatigability' reported by participants at 5- or 10-year follow-up after graduation. RESULTS: The unadjusted risk in women was 5.0 (95% exact confidence interval =1.4 to 17.4) and in men was 1.7 (95% exact confidence interval = 0.8, to 3.5). CONCLUSION: These preliminary findings suggest that hypotension may be a risk factor for the development of idiopathic chronic fatigue in women. PMID: 15126909
