Article Synopsis
- * Conducted with 685 participants aged 8-15 years, it involved measuring various physical attributes and analyzing their correlation with the 2D:4D ratio.
- * Results indicate a significant positive correlation in girls between 2D:4D and measurements like waist circumference and skinfold thickness, while no such correlations were found in boys.
Background: Children's eating behaviors, body shape and body image cognition may be more susceptible to the influence of their parents, but these influences may be weakened with age. There may be different association pathways between parental pressure on children's body image (PPCBI), body mass index (BMI), body image dissatisfaction (BID) and eating disorders (EDs) among children and adolescents at different developmental stages.
Methods: The stratified cluster sampling method (Stratified by grade, and took the classes as clusters) was used to select 486 students aged 8-15 years in two 9-year schools.
Background: Physical activity and eating behavior are associated with hypertension in children and adolescents. Revealing the associations between physical activity patterns, eating behavior patterns and high blood pressure (HBP) could help improve the problem of hypertension from the actual children's physical activities and eating behaviors.
Methods: A total of 687 students aged 8-15 years were selected from two nine-year primary and secondary schools using stratified cluster random sampling method.
Objectives: The time of onset of puberty has been increasingly earlier, but its mechanism is still unclear. This study aimed to reveal the mechanism of leptin and NPY in the onset of puberty in male offspring rats after androgen intervention during pregnancy.
Methods: Eight-week-old specific pathogen-free (SPF) healthy male Sprague-Dawley (SD) rats and 16 female SD rats were selected and caged at 1:2.
An Association Between 5, -1α Genetic Variants and Obesity in Chinese Children: A Case-Control Study.

Background: Fibronectin type III domain containing protein 5 () gene encodes irisin that regulates adipose tissue metabolism. Peroxide-proliferator-activated receptor γ coactivator 1α () is a powerful promoter of mitochondrial biosynthesis and oxidative metabolism, which plays an important role in inducing heat production and energy consumption of brown fat. expression stimulated an increase in expression of .

The aim of this study was to analyze the associations between negative gender attitudes and eating behaviors among Chinese children and adolescents.
Methods: Primary and secondary school students aged 8-15 years were selected as participants using a stratified cluster random sampling method.
Article Synopsis
- The study investigated the relationship between hormone levels in the blood of pregnant women and their newborns, focusing on androgens such as testosterone (T), free testosterone (FT), dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), and sex hormone-binding globulin (SHBG).
- Results showed that male newborns had higher levels of cord blood T, FT, and DHT compared to females, while also noting different levels of hormones between prenatal and cord blood.
- Various association paths were identified for both male and female neonates, indicating how prenatal hormone levels influenced their cord blood counterparts, highlighting a complex interplay between these hormones.
Objective: Children at different developmental stages show different physical development and psychological cognitive characteristics and may pay different attention to body parts. The purpose of this study was to analyze the associations between body image dissatisfaction (BID) and body anthropometric indices (BAIs) among Chinese children and adolescents at different developmental stages.
Methods: A total of 609 Chinese primary and secondary school students aged 8-15 years (329 boys and 280 girls) were selected using stratified cluster sampling.
Background: Body image dissatisfaction and aggressive behavior have become important public health problem in children and adolescents, and body image dissatisfaction may increase the occurrence of aggressive behavior. The aim of this study was to explore the correlation between body image dissatisfaction and aggressive behavior among Chinese children in different developmental stages.
Methods: The stratified cluster sampling method was used to effectively survey 518 children aged 8-15 years.
Article Synopsis
- The research aimed to investigate how body mass index (BMI), sex hormones, leptin, and irisin are related in children and teens with varying body types.
- A total of 366 students (ages 8-15) were analyzed, measuring BMI and serum concentrations of leptin, irisin, oestradiol (E2), and testosterone (T), highlighting significant differences between normal-weight and overweight/obese individuals.
- The findings suggested that while BMI did not directly affect irisin levels, there were indirect influences through leptin, with notable negative pathways linking sex hormones to leptin and irisin in different body types.
