Review Randomized Controlled Trial Comparative Study Clinical TrialOral contraceptive use among female elite athletes and age-matched controls and its relation to low back pain.
Exogenous and endogenous female sex steroids may influence the risk of low back pain. The fact that back pain is a very common symptom during pregnancy supports this theory. Back pain is also more common among female than male athletes. Oral contraceptives have been suggested to increase the risk of low back pain. ⋯ This study does not support the theory that low back pain is affected by the use of oral contraceptives. Instead, constitutional factors and mechanical stress during intense physical activity is probably more important.
