Insights into associations between Life's essential 8 and lung function from NHANES data

Area of Science:

• Cardiovascular Health
• Pulmonary Function
• Public Health

Background:

• The American Heart Association's Life's Essential 8 (LE8) assesses cardiovascular health.
• Limited research exists on LE8's impact on lung function.
• Understanding this link can inform public health strategies for respiratory wellness.

Purpose of the Study:

• To investigate the association between LE8 scores and lung function.
• To explore how LE8 components correlate with lung function metrics.
• To evaluate LE8's potential as an indicator for respiratory health.

Main Methods:

• Utilized National Health and Nutrition Examination Surveys (NHANES 2007-2012) data from 10,400 participants.
• Calculated lung function (FEV1 Z-score) and LE8 scores.
• Employed regression models and restricted cubic splines to analyze correlations.

Main Results:

• Higher LE8 scores showed a positive association with improved lung function.
• Favorable diet, physical activity, reduced nicotine exposure, and better sleep correlated with better lung function.
• BMI, blood lipids, glucose, and blood pressure had variable effects.

Conclusions:

• Life's Essential 8 scores are significantly associated with lung function.
• Better cardiovascular health behaviors, as measured by LE8, correlate with enhanced lung function.
• LE8 may serve as a valuable tool for assessing and promoting respiratory health.
