Longitudinal association between dysmenorrhoea in adolescence and chronic pain in adulthood: a UK population-based study.

Background: Dysmenorrhoea affects many adolescents and often goes untreated for various sociocultural reasons. Dysmenorrhoea frequently co-occurs with other chronic pain conditions, and adult women with dysmenorrhoea have greater sensory sensitivity compared with controls. We aimed to test the hypothesis that adolescent dysmenorrhoea leads to the development of general chronic pain, including pain outside the pelvis, by estimating the risk of chronic pain in adulthood following the experience of dysmenorrhoea at age 15 years.

Effect of Plant Versus Animal Protein on Muscle Mass, Strength, Physical Performance, and Sarcopenia: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Context: Dietary protein is recommended for sarcopenia-a debilitating condition of age-related loss of muscle mass and strength that affects 27% of older adults. The effects of protein on muscle health may depend on protein quality.

Objective: The aim was to synthesize randomized controlled trial (RCT) data comparing plant with animal protein for muscle health.

The effect of animal versus plant protein on muscle mass, muscle strength, physical performance and sarcopenia in adults: protocol for a systematic review.

Background: The evidence base for the role of dietary protein in maintaining good muscle health in older age is strong; however, the importance of protein source remains unclear. Plant proteins are generally of lower quality, with a less favourable amino acid profile and reduced bioavailability; therefore, it is possible that their therapeutic effects may be less than that of higher quality animal proteins. This review aims to evaluate the effectiveness of plant and animal protein interventions on muscle health outcomes.
