Article Abstract
: Gait kinematic and kinetic changes have been identified in older adults, highlighting the need to explore the principal age-related components and how these are associated with functional disability. This study aims to perform a factor analysis, including gait kinematic and kinetic parameters in older adults to establish determinant gait domains. Additionally, this study aims to identify which domains differentiate those without and with functional disability. : Through a cross-sectional design, older adults aged 60 and over (n = 35 without and n = 25 with functional disability) were analyzed during overground gait. A principal component analysis (PCA) was used to determine principal components from gait parameters previously demonstrated to express age-related effects (spatiotemporal parameters, sagittal ankle moment and power, ground reaction forces peak, and tridimensional lower limb joints range of motion and positions at heel strike and toe-off). : , , , , , , , control, , and domains explained 83.90% of the total gait variance in older adults. and distinguished individuals with disabilities. : PCA identified ten gait domains in older adults. and distinguished disabilities, revealing cautious walking patterns and weaker hip abductor strength.

Background: A plant-focused, healthy dietary pattern, such as the Mediterranean diet enriched with dietary fiber, polyphenols, and polyunsaturated fats, is well known to positively influence the gut microbiota. Conversely, a processed diet high in saturated fats and sugars negatively impacts gut diversity, potentially leading to weight gain, insulin resistance, and chronic, low-grade inflammation. Despite this understanding, the mechanisms by which the Mediterranean diet impacts the gut microbiota and its associated health benefits remain unclear.

Objectives: This study investigated the cost-effectiveness of an early childhood obesity prevention intervention providing telephone and short message service (SMS) support to mothers of children aged 2-4 years by socioeconomic position (SEP).
Methods: A model-based SEP-specific economic evaluation of the intervention was conducted. SEP-specific intervention costs and effects at age 5 years were derived from the trial data and applied to a cohort of 4- to 5-year-old Australian children.

Objective: To systematically evaluate the association between anthropometric parameter and myopia in children and adolescents.
Methods: PubMed, Web of Science, EBSCO, Embase, CNKI, CBM, WanFang Data, and VIP databases were searched from inception to June, 2025. We collected cross-sectional studies on the association between anthropometric parameter and myopia in children and adolescents aged 0-25 years, including body mass index (BMI) and weight-adjusted waist index (WWI).
