Article Abstract
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). After independently screening the literature, extracting the data and evaluating the risk of bias in the included studies by 2 researchers, meta-analysis was performed using Stata 18.0 software.
Results: A total of 18 cross-sectional studies were included, from which 1,505,099 participants were analyzed. Meta-analysis results suggested a positive relationship between anthropometric parameters and myopia. The pooled OR for overweight was 1.27 (95%CI: 1.08 ~ 1.51; I = 81.6%; P < 0.001). After excluding outliers, the pooled OR for overweight was 1.14 (95% CI: 1.13 ~ 1.15; I = 0.0%; P = 0.444). The pooled OR for obesity was 1.25 (95%CI: 1.12 ~ 1.39; I = 88.3%; P < 0.001). The results demonstrated inconsistency when subgroup analyses were performed based on age, geographic regions, visual acuity measurement methods, sample characteristics, whether covariates were adjusted in the original data, and whether one of 3 main confounders (parental myopia, outdoor time, or near work) was controlled. Results of meta-regression analysis showed that the publication year was not a source of heterogeneity across overweight, obesity and BMI/WWI groups. Subgroup evaluation revealed that a pooled value was 1.08 (95%CI: 1.00 ~ 1.18; I = 88.9%; P < 0.001) for BMI in BMI/WWI group. The results of Egger's test also suggested that there was no significant publication bias in overweight, obesity, and BMI/WWI groups, respectively.
Conclusions: Our findings support that anthropometric parameter was significantly associated with myopia in children and adolescents. However, given the limitations of the included cross-sectional studies, prospective studies are warranted to further investigate this issue.

Background: Sedentary behavior (SB) and the absence of physical activity (PA) have become increasingly prevalent in modern societies due to changes in physical and social-environmental conditions, particularly in university students. This cross-sectional study aimed to describe and identify the prevalence and correlates of self-reported and accelerometer-determined SB and PA of German university students.
Methods: A convenience sample of 532 students participated in a questionnaire survey during the lecture period in the summer term 2018.

Background: The appearance of pubic or axillary hair before the age of eight in girls or nine in boys, without other signs of puberty, is defined as premature adrenarche (PA) and may be an early sign of the metabolic syndrome. The second to fourth digit ratio (2D:4D), thought to reflect prenatal androgen exposure, has been associated with a variety of behavioral, metabolic, and hormonal conditions.
Objective: To evaluate the relationship between 2D:4D digit ratios and anthropometric, metabolic, and hormonal parameters in children with PA.
The Effect of Ginseng Supplementation on Cardiovascular Disease Risk Factors: A Comprehensive Systematic Review and Dose-Response Meta-Analysis.

Systematic Review and Meta-Analysis Expert Group (SRMEG), Universal Scientific Education and Research Network (USERN), Tehran, Iran.
Although numerous clinical studies suggest that ginseng supplementation may benefit cardiovascular disease (CVD) risk factors, results remain inconclusive. This systematic review and meta-analysis evaluated the effects of ginseng supplementation on CVD-related risk factors. Relevant studies were identified through electronic searches in Embase, Web of Science, Scopus, PubMed, and CENTRAL up to August 2024.

Background: Periodontitis, a chronic inflammatory disease of tooth-supporting tissues, shows significant associations with systemic conditions like type 2 diabetes mellitus (T2DM) and obesity. These metabolic disorders share chronic inflammatory pathways that may influence periodontal disease severity. This study investigated these relationships using advanced quantifiable metrics - periodontal epithelial surface area (PESA) and periodontal inflammatory surface area (PISA).

Objectives: This study aimed to investigate the relationship between the relative age effect (RAE) and success in ice hockey during adolescence and adulthood in male Swedish players, as well as potential interactions between relative age (RA) and biological maturation.
Methods: Anthropometric data were collected from high schools with a certified ice hockey programme over 20 years. Birth dates were extracted from public databases to calculate numerical relative age (n = 2211 players).
