Objective To test the validity of Benjamin Franklin's maxim early to bed and early to rise makes a man healthy, wealthy, and wise : Design Cross sectional analysis of sleeping patterns in a nationally representative group of elderly people, and longitudinal investigation of mortality.
Setting Eight areas in Britain (five in England, two in Scotland, and one in Wales).
Subjects 1229 men and women aged 65 and over who in 1973-4 had taken part in a survey funded by the Department of Health and Social Security and for whom data on sleeping patterns, health, socioeconomic circumstances, and cognitive function had been recorded.
Main outcome measures Self reported income, access to a car, standard of accommodation, performance on a test of cognitive function, state of health and mortality during 23 years of follow up.
Results 356 people (29%) were defined as larks (to bed before 11 pm and up before 8 am) and 318 (26%) were defined as owls (to bed at or after 11 pm and up at or after 8 am).
There was no indication that larks were richer than those with other sleeping patterns.
On the contrary, owls had the largest mean income and were more likely to have access to a car.
There was also no evidence that larks were superior to those with other sleeping patterns with regard to their cognitive performance or their state of health. (...)
