Risk of ischemic heart disease in relation to the traditional risk factors and delivery of a small for gestational age infant in a multivariable analysis.
Multivariable logistic regression model of preterm birth included all investigated traditional risk factors for ischemic heart disease and SGA. IHD, ischemic heart disease. SGA, delivery of a small for gestational age infant, a term live born infant with birth weight <2500 g. No SGA, prior delivery of a term live born infant that was not small for gestational age. Smoking, smoked at least 100 cigarettes in lifetime. Low fiber diet, less than 25 g of fiber consumed daily. Antihyperlipidemic med., use of antihyperlipidemic medication at the time of examination. BMI, body mass index≥30. Inactivity, number of hours spent daily watching television or in front of the computer. Income, annual household income reported in $5,000 increments. Detectable cotinine, serum cotinine concentrations ≥0.05 ng/mL. Alcohol, no alcohol use comparing to a moderate <15 g/day alcohol consumption. Total cholesterol, total serum cholesterol ≥240 mg/dl. LDL cholesterol, LDL serum cholesterol ≥160 ng/ml. HDL cholesterol, HDL serum cholesterol <35 mg/dl. Triglycerides, serum triglycerides ≥200 mg/dl. Serum CRP, serum C-reactive protein ≥1 mg/dl. Hgb A1c, concentration of Hemoglobin A 1c >5.6%. OR (95% CI), population weighted odds ratios and 95% confidence intervals of ischemic heart disease in women with prior live term birth. The odds ratios and 95% confidence intervals were obtained using weighted logistic regression accounting for the sampling scheme of the survey and adjusted for all risk factors of ischemic heart disease.
