It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke.
The reason for this observation has not been clear.
This study aimed to examine the lifelong relation between body fat and stroke to shed light on why the public health risks of overweight and obesity have tended to be obscured in previous epidemiological studies.
Eleven general practices in west Birmingham.
Altogether 125 men and women who had just had their first stroke and were aged 35-74 years and 198 controls frequency matched for age and sex were recruited over 24 months during 1988-90.
Those in both the thinnest and fattest quartiles of subscapular skinfold thickness were at increased risk of stroke compared with those in the middle quartiles (age adjusted odds ratios 2.12 (95% confidence interval (CI) 1.2,3.9) and 2.08 (1.1,3.8) respectively).
When lifelong maximum reported body mass index was assessed the hazards of obesity but not leanness were seen and multiple risk factor adjusted.
Potentially important risks of excessive body fat for stroke can be obscured by both a history of cigarette smoking and thinness associated with deteriorating health.
The results seem to explain why excess body fat has previously been consistently related to hypertension and diabetes mellitus but less consistently to stroke.
