Maternal periconceptional noise exposure was assessed using standardized questionnaires, capturing exposure duration, perceived interference, and dominant noise sources (traffic, construction, and industrial). Multivariable logistic regression estimated odds ratios (ORs) and 95% CIs, adjusting for potential confounders. Restricted cubic spline analysis assessed nonlinear exposure\u2013response relationships.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Maternal periconceptional noise exposure was associated with increased CHD risk (OR, 1.81; 95% CI, 1.36\u20132.40). Compared with no noise exposure, exposure for 4 to \u22648 hours per day was associated with higher risk (OR, 3.24; 95% CI, 2.02\u20135.20), as was exposure for more than 8 hours per day (OR, 2.07; 95% CI, 1.19\u20133.58). Traffic noise (OR, 1.75; 95% CI, 1.20\u20132.56) and construction and industrial noise (OR, 2.13; 95% CI, 1.29\u20133.50) were also independently associated with increased risk. Restricted cubic spline analysis indicated a positive nonlinear association between noise exposure duration and CHD risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Maternal periconceptional exposure to environmental noise was associated with increased CHD risk in offspring, particularly with prolonged exposure and specific sources such as traffic and construction.
