Here is how your health risks increase at different BMIs(体重指数) if your waist circumference（腰围） is higher than 40 inches（102 cm） in men and 35 inches （88 cm） in women:
·If your BMI is in the 18.5 to 24.9 range, or “Normal”, then a larger waist that is near or greater than 40 inches for men and 35 inches for women can indicate that you are at “increased” risk.
·If your BMI is in the 25 to 29.9 range, or “Overweight”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “increased” risk. Above these sizes,the risk is considered “high”.
·If your BMI is in the 30 to 34.9 range, or “Obese(肥胖症)I”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “high” risk. Above these sizes, the risk is considered “very high.”
·If your BMI is in the 35 to 39.9 range, or “Obese II”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “very high” risk. Above these sizes, the risk is still considered “very high”.
·If your BMI is or in the 40 + range, or “Obese III”, then a larger waist (less than or equal to 40 inches for men and 35 inches for women) can indicate that you are at “extremely high” risk. Above these sizes, the risk is still considered “extremely high”.
