Table 3.

Age-adjusted odds ratio (and 95% confidence intervals) for self-reported OA across BF% categories stratified by BMI groups and sex

	BMI	Underweight/Normal	Overweight
	Body Fat Percentage	(BMI < 25 kg/m2)	(BMI 25–29.99 kg/m2)
Female	Athletic/Acceptable	Reference	Reference
	Overweight/Obese	1.92 (0.81,2.87)	1.84 (1.18,3.19)*
		(n = 711)	(n = 556)
Male	Athletic/Acceptable	Reference	Reference
	Overweight/Obese	1.41 (0.61,2.39)	1.32 (1.12,2.79)*
		(n = 394)	(n = 801)

All four models were adjusted for age; Individual body fat percentages were grouped into three body fat categories: athletic/good (males: < 14% females < 23%), acceptable (males 15–20%, females 24–30%), or overweight/obese (male > 21% females > 31%).;* p-value< 0.05
