Key result
Being born during the coldest months was associated with increased coronary heart disease prevalence in later life compared to warmer months (age-adjusted OR 1.24; 95% CI 1.03-1.50).
Why the study?
Does cold outdoor temperature at birth increase the risk of coronary heart disease and insulin resistance in later life in women?
Cross-Sectional (n=4,286)
Yes
Does cold outdoor temperature at birth increase the risk of coronary heart disease and insulin resistance in later life in women?
Odds Ratio: 1.24 (95% CI 1.03–1.5)
Cold outdoor temperature at birth is associated with increased prevalence of coronary heart disease and insulin resistance in later life, particularly among those from lower socioeconomic backgrounds in childhood.

Should not yet inform clinical risk assessment; leaves open whether cold exposure or confounders drive later CHD risk.
Gian M. Novaro (2004) reported a cross-sectional. Cold outdoor temperature at birth vs. Warmer outdoor temperature at birth (remaining three quarters) was evaluated on Coronary heart disease prevalence (OR 1.24, 95% CI 1.03 to 1.50). Being born during the coldest months was associated with increased coronary heart disease prevalence in later life compared to warmer months (age-adjusted OR 1.24; 95% CI 1.03-1.50).
