Cartilage contact characteristics of the knee during gait in individuals with obesity.

Obesity increases the risk of knee osteoarthritis (OA). Knee joint contact characteristics have been thought to provide insights into the pathogenesis of knee OA; however, the cartilage contact characteristics in individuals with obesity have not been fully described. We conducted cartilage-to-cartilage contact analyses through high-precision fluoroscopy imaging with subject-specific magnetic resonance cartilage models.

Weight loss changed gait kinematics in individuals with obesity and knee pain.

Background: Obesity is a mechanical risk factor for osteoarthritis. In individuals with obesity, knee joint pain is prevalent. Weight loss reduces joint loads, and therefore potentially delays disease progression; however, how the knee joint responds to weight loss in individuals with obesity and knee pain is not clear.

Improved Financial Capability Can Reduce Material Hardship among Mothers.

This study draws on the theoretical framework of financial capability in investigating whether financial access (that is, availability of financial products and services) and financial knowledge (that is, understanding of basic financial concepts) can influence the risk of material hardship. Authors examine the possibility of direct associations as well as of indirect ones in which financial management (that is, individual financial behaviors) serves as a mediator. The probability sample of mothers with young children born in Oklahoma during 2007 (N = 2,529) was selected from Oklahoma birth certificates.
