Summary
This summary is machine-generated.Social jetlag (SJL) is linked to negative changes in body composition and adiposity in females from adolescence to young adulthood. This association was not observed in males.
Area Of Science
- Chronobiology
- Human Physiology
- Public Health
Background
- Social jetlag (SJL), the discrepancy between internal biological rhythms and social schedules, is implicated in obesity and metabolic dysfunction.
- Understanding the long-term effects of SJL on body composition is crucial for public health interventions.
- Sex-specific differences in the impact of SJL on health are increasingly recognized.
Purpose Of The Study
- To investigate the relationship between social jetlag (SJL), adiposity, and body composition.
- To examine these associations longitudinally from adolescence to young adulthood.
- To determine if these relationships differ between sexes.
Main Methods
- A longitudinal study included 525 adolescents with complete adolescent and adult measurements.
- Assessed changes in body mass index (BMI), waist and hip circumferences, waist-to-hip ratio, waist-to-height ratio, and fat and lean mass percentages.
- Analyzed associations between adolescent SJL and subsequent changes in body composition.
Main Results
- In females, adolescent SJL correlated with BMI z-score, hip circumference, and fat and lean mass percentages.
- Longitudinal analysis showed adolescent SJL predicted increased fat mass, waist-to-height ratio, and waist and hip circumferences in adult women.
- No significant associations were found for males in either cross-sectional or longitudinal analyses.
Conclusions
- Social jetlag is associated with detrimental changes in adiposity and body composition in females during the transition from adolescence to young adulthood.
- These findings highlight potential sex-specific vulnerabilities to SJL.
- Further research may explore targeted interventions for females experiencing SJL.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
The hypodermis (the subcutaneous layer or superficial fascia) is present directly below the dermis. It connects the skin to the underlying fascia (fibrous tissue) of the bones and muscles. It is not strictly a part of the skin, although the border between the hypodermis and dermis can be difficult to distinguish. The hypodermis consists of well-vascularized, loose, areolar connective tissue and adipose tissue, which functions as a mode of fat storage and provides insulation and cushioning for...
