The maximum weight prior to the onset of diabetes was studied in 177 patients.
The results were as follows:
1) Overweight (10 per cent or more over standard weight) was shown in 74.5 per cent of 177 patients, normal weight in 24.9 per cent and underweight in 0.5 per cent.
2) Remarkable overweight (40 per cent or more over standard weight) was found more frequently in the patients whose onset of diabetes was over 40 years old.
3) Remarkable overweight was more frequently in the male than in the female. 4) Within 2 years after showing the maximum body weight the clinical onset of diabetes was seen in 51 per cent of 177 diabetics, and within 10 years in 73 per cent of the patients.
5) Within 10 years after showing the maximum body weight the onset of diabetes was found in 50 per cent of the patients in 3 decade, 90 per cent in 4 decade, and 100 per cent in 5 decade.The duration between the manifestation of maximum body weight and the onset of diabetes was shorter in the older decade.
