Abstract

Introduction:

The association between sedentary lifestyle, physical activity, and risk of respiratory diseases is a crucial area of medical and health research. Despite numerous studies, uncertainties and controversies regarding the causal relationships persist. We utilized Mendelian randomization (MR) analysis, an advanced statistical tool, to further investigate causal links.

Methods:

In this study, bidirectional MR analysis was performed to determine the potential causal relationships between leisure screen time (LST), moderate-to-vigorous intensity physical activity during leisure time (MVPA), sedentary behavior at work (SBW), and 10 common respiratory diseases.

Results:

Aggregating outcomes from analytical assessments showed that LST was positively correlated with the risk of asthma (odds ratio [OR] = 1.22, 95% confidence interval [CI] = 1.10-1.34, p = 9.36E-5), chronic obstructive pulmonary disease (COPD) (OR = 1.31, 95% CI = 1.16-1.49, p = 2.45E-5), lung cancer (OR = 1.18, 95% CI = 1.05-1.32, p = 0.005), and obstructive sleep apnea (OR = 1.12, 95% CI = 1.04-1.22, p = 0.003). MVPA was correlated with a reduced risk of developing asthma (OR = 0.68, 95% CI = 0.53-0.88, p = 0.004) and COPD (OR = 0.62, 95% CI = 0.47-0.83, p = 0.001). A genetic predisposition to SBW was associated with a decreased risk of nasal polyps (OR = 0.60, 95% CI = 0.423-0.86, p = 0.005).

Conclusion:

Our findings demonstrate complex causal relationships among sedentary lifestyle, physical activity, and various respiratory system diseases. These discoveries hold significant value in devising precision-oriented approaches for the prevention and treatment of respiratory diseases.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Lung Capacity

Lung Capacity

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Pleiotropy

Pleiotropy

Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Behavioral Genetics and Its Designs

Behavioral Genetics and Its Designs

Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

Nature and Nurture

Nature and Nurture

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,...
