This study investigated the association between energy and macronutrient intake and bone health in 63 adolescents of both sexes who participated in volleyball, track and field, or swimming. Bone mineral content (BMC) and density (BMD) of the total body less head (TBLH), lumbar spine (L1-L4), and femoral neck were assessed using DXA. Bone geometry parameters, including cross-sectional area (CSA), cross-sectional moment of inertia (CSMI), and section modulus, were estimated.

Method: The study included adolescent (11-18 years) athletes, of both sexes, who practiced basketball (n = 26) or track and field (n = 24). Skeletal muscle mass was measured by bioelectrical impedance analysis.
Background: This study aimed to compare the prevalence of excess weight in adolescents living in Florianópolis, Santa Catarina, Brazil, from 2007 to 2017/2018 and assess associations with physical activity level, screen time, muscle strength, and cardiorespiratory fitness.
Methods: Two cross-sectional surveys were conducted with adolescents (14 to 19 years old). The body mass index was calculated from measurements of body weight (kg) and height (m2).
Objective: This study aimed to assess the mediation effects of lean mass and fat mass on the relationship between body mass index (BMI) and handgrip strength (HGS) in adolescents.
Method: The sample included 118 adolescents (60 girls) aged 10-14 years. Body composition, determined from lean mass (LM) and fat mass (FM), was measured by dual-energy x-ray absorptiometry.
Objective: The aim of this study was to analyze isolated and combined associations of physical inactivity excessive screen time with negative self-rated health, according to sex, among school adolescents.
Methods: In this cross-sectional study conducted with 2,517 adolescents in Amazonas State, participants were asked about their self-rated health with the following question: How do you rate your health? Responses were dichotomized into positive (excellent and good) and negative (regular, bad, and terrible). Information on sex, age group, family income, physical activity, and screen time (watching TV, using a computer, or playing video games) was collected through a self-administered questionnaire.
Article Synopsis
- * The study found that in normal-weight adolescents, both lean mass (LM) and fat mass (FM) positively correlated with bone mineral content (BMC), while in overweight adolescents, only LM was significantly linked to BMC.
- * Lean mass emerged as the primary predictor of bone mass for both groups, highlighting its importance for bone health and the need for activities that encourage LM growth to mitigate future fracture risks.
: This study aimed to verify the agreement between body mass index (BMI) and body fat in adolescents with different physical activity (PA) levels. : This cross-sectional study collected body fat data in 118 adolescents (aged 10 to 14 years) estimated using air-displacement plethysmography (ADP). Body mass 10 and height were used to calculate BMI.

This cross-sectional study aimed to identify HGS levels and associated modifiable and non-modifiable risk factors in adolescents.
Methods: The study included 971 adolescents (496 boys) aged 15-18 years.
Adolescence is an important period for the acquisition of bone mass, which can be enhanced by several factors. This study aimed examine the relationships of handgrip strength, free-fat mass, and fat mass with bone mineral density in adolescents. 118 adolescents (60 girls), aged 10 to 14 years, participated in the study.

Methods: A total of 960 adolescents (494 boys) aged 15-18 years old participated in this study. The dependent variable was WHtR; independent variables were self-reported age, economic level, sexual maturation, physical activity level, screen time, and body fat.
