Brown WJ et al. Int J Obes 1998;22:520-528. Data in the next 8 slides show results of a population-based longitudinal study by Brown and colleagues. The Australian Longitudinal Study on Womens Health enrolled 13,431 women who participated in a baseline survey of selected indicators of health and well-being for middle-aged women, age 45-49. The study explored the associations between body mass index and selected indicators of health and well-being; surgical procedures(cholescystectomy, hysterectomy), symptoms like back pain, and number of visits to general practitioners or specialists. BMI was calculated using self-reported height and weight, corrected following the method of Waters. Hypertension shows a strong monotonic relationship with BMI. Trend curve estimates the relationship between BMI and hypertension . The percentage of reported hypertension . . .

Relationship between BMI and crude percentage of women reporting medical problems, surgical procedures, symptoms, and health care utilization. The percentage of women reporting constant tiredness in the study by Brown and colleagues increases with increasing body mass index. This graph shows the trend curve estimated to show the relationship between BMI and constant tiredness. There is a J-curve associated with tiredness. Women with BMI < 20 report higher feelings of tiredness than those with BMI between 20 and 30, and are almost equivalent to those with BMI between 30 and 40. There is a 70% increase in odds ratio between women with BMI < 20 and those with BMI > 40. Page 15 BACKGROUND V 7 BMI P e r c e nt a ge 20 25 30 35 40 4 . . .
