The aim of this systematic review is to determine the current evidence on sex differences in the association between risk factors and knee osteoarthritis (KOA) and their prevalence. The results showed that women are associated with high BMI, alcohol consumption, atherosclerosis, and high vitamin E levels, while men are associated with high physical activity, soft drink consumption, and abdominal obesity. Knee injury, high blood pressure, and low step rate seem to affect both women and men. However, more high-quality studies are needed to assess the impact of sex differences on risk factors for KOA, especially for symptomatic/clinical OA.
Objectives Previous systematic reviews focused on the evidence of common risk factors for knee OA (KOA); however, the effect and strength of association between risk factors and KOA might be different between the two sexes. The aim of the present systematic review was to determine the current evidence on sex differences in the association between risk factors and KOA and their prevalence. Methods We searched the following electronic bibliographic databases: MEDLINE (PubMed), EMBASE and Web of Science. A methodological quality assessment was conducted independently by two researchers according to an adapted version of the standardized set of criteria known as the Newcastle-Ottawa Quality Assessment Scale (NOS). The NOS, a star system, was converted to three categories of quality. Results In total, 27 studies reported sex-specific risk estimates on several risk factors for KOA. Out of the 22 longitudinal cohort studies (except one nested case-control), 12 were of good quality and 10 were of fair quality. The five cross-sectional studies consisted of one of good, three of fair and one of poor quality. There was an indication of sex differences in risk factors leading to higher risk of KOA: high BMI, alcohol consumption, atherosclerosis and high vitamin E levels in women, and high physical activity, soft drink consumption and abdominal obesity in men. Knee injury, high blood pressure and low step rate seem to affect both women and men. Conclusion More good quality studies are needed to assess sex differences in risk factors for KOA, especially for symptomatic/clinical OA.
