This study sought to evaluate the associations between changes in glycemic status and changes in total body (TB), trunk, and appendicular fat (FM) and lean mass (LM) in men. A population-based study of men aged 20⁻66 years at baseline were included in cross-sectional ( = 430) and three-year longitudinal ( = 411) analyses. Prediabetes was defined as fasting glucose 100⁻125 mg/dL. Type 2 diabetes (T2D) was determined by: self-reported diabetes, current anti-diabetic drug use (insulin/oral hypoglycemic agents), fasting glucose (≥126 mg/dL), or non-fasting glucose (≥200 mg/dL). Body composition was evaluated by dual-energy X-ray absorptiometry. Longitudinal analyses showed that changes in TB FM and LM, and appendicular LM differed among glycemic groups. Normoglycemic men who converted to prediabetes lost more TB and appendicular LM than men who remained normoglycemic (all, < 0.05). Normoglycemic or prediabetic men who developed T2D had a greater loss of TB and appendicular LM than men who remained normoglycemic (both, < 0.05). T2D men had greater gains in TB FM and greater losses in TB and appendicular LM than men who remained normoglycemic (all, < 0.05). Dysglycemia is associated with adverse changes in TB and appendicular LM.

Health implications of racial differences in serum growth differentiation factor levels among men with obesity.
Physiol Rep

Division of Endocrinology Diabetes and Metabolism at Baylor College of Medicine, Houston, Texas, USA.
Article Synopsis
- The study examined the role of Growth differentiation factor (GDF15) in relation to health markers in obese men of different racial and ethnic backgrounds.
- It involved 193 participants and assessed various health metrics including body composition, hormonal levels, and bone mineral density.
- Findings indicated that GDF15 levels were higher in non-African Americans than in African Americans, and its relations to glucometabolic status and body composition varied by ethnicity, highlighting potential racial differences in health risks.
The gut microbiota genus Blautia is associated with skeletal muscle mass reduction in community-dwelling older Japanese adults: the Wakayama Study.

Department of Cardiology, Sumiya Rehabilitation Hospital, Wakayama, Japan.
Purpose: This cross-sectional study examined the gut microbiota species associated with skeletal muscle mass reduction in a community-based sample of older Japanese adults.
Methods: The study included 744 participants (320 men and 424 women) aged 65-89 years (mean age: 73 years) with no history of treatment for colorectal, chronic kidney, or liver diseases. Bioelectrical impedance analysis was performed to estimate the appendicular skeletal muscle mass (ASM) of each participant.
Exploring the association between muscle mass and thyroid function in Chinese community subjects over 45 years old with normal thyroid function: a cross-sectional analysis.

Article Synopsis
- - This study aimed to explore the relationship between muscle mass and thyroid hormone levels in middle-aged and elderly Chinese individuals who have normal thyroid function, focusing on a sample of 1,868 participants.
- - Results indicated a significant association between low muscle mass and lower levels of thyroid hormones FT3 and FT4, while no significant correlation was found with TSH or FT4 after adjusting for confounding factors like age and health conditions.
- - The findings suggest that higher muscle mass is positively correlated with higher levels of FT3/FT4, consistent across different demographic groups such as age, gender, and weight.

Introduction: The finger-ring test (FRT) offers a simple method to screen older adults at increased risk of sarcopenia.
Objective: To investigate the association between the FRT and lean soft tissue mass estimated by dual-energy X-ray absorptiometry (DXA), and to further elucidate the FRT as an indicator of muscle mass, while accounting for potential confounders, in a community-dwelling population.
Materials And Methods: Within this cross-sectional study 430 community-dwelling individuals aged 18 to 79 (286 women (66.
Diet quality from mid-life and body composition in older age: findings from a British birth cohort.

We investigated associations between 'healthy dietary pattern' scores, at ages 36, 43, 53 and 60-64 years, and body composition at age 60-64 among participants from the MRC National Survey of Health and Development (NSHD). Principal component analyses of dietary data (food diaries) at age 60-64 were used to calculate diet scores (healthy dietary pattern scores) at each age. Higher scores indicated healthier diets (higher consumption of fruit, vegetables and wholegrain bread).
