New research shows that many people are unaware of their weight's effect on their health. Some who are underweight still try to diet and some who are overweight classify themselves as being at the proper weight or underweight. The study from the University of Texas Medical Branch (UTMB) found that nearly 25% of overweight and obese women believed themselves to be at normal or even underweight, and many who were normal or underweight reported that they still diet to lose weight.
The researchers say that this misperception is dangerous, for both groups. Being overweight increases the risk of type-2 diabetes, heart disease, arthritis, and several other conditions. Being underweight is likewise risky with a weakened immune system and troubles with fertility and even hair loss.
The study looked at 2200 women aged 18-25. They were asked questions about their weight, activity level and socio-demographic variables. Study participants also reported the number of days they had exercised and any unhealthy weight-related behaviors like taking diet pills or skipping meals. Those who didn't recognize themselves as being overweight were much less likely to engage in healthy or unhealthy weight related behaviors and those who mistakenly thought they were overweight were more than twice as likely to skip meals or diet.
Study authors believe that people whose peers are similarly over- or underweight are more likely to believe that their own weight is normal. Researchers suggest that in order to give clarity on the matter, BMI should be a part of routine screenings during checkups. Just as a physician would tell you if your blood pressure was too high, the physician should also tell you if your BMI is too high or too low.
