Does malnutrition in utero determine diabetes and coronary heart disease in adulthood? Results from the Leningrad siege study, a cross sectional study

Abstract Objective: To investigate the relation between decreased maternal food intake and risk factors for coronary heart disease in adult Design: Cross sectional study. Subjects: 169 subjects exposed to malnutrition in utero (intrauterine group) during the siege of Leningrad (now St Petersburg) in 1941-4; 192 subjects born in Leningrad just before rationing began, before the siege (infant group); and 188 subjects born concurrently with the first two groups but outside the area of the siege (unexposed group). Setting: Ott Institute of Obstetrics and Gynaecology, St Petersburg. Main outcome measures: Development of risk factors for coronary heart disease and diabetes mellitus—obesity, blood pressure, glucose tolerance, insulin concentrations, lipids, albumin excretion rate, and clotting factors. Results: There was no difference between the subjects exposed to starvation in utero and those starved during infant life in: (a) glucose tolerance (mean fasting glucose: intrauterine group 5.2(95% confidence interval 5.1 to 5.3), infant group 5.3 (5.1 to 5.5), P=0.94; mean 2 hour glucose: intrauterine group 6.1 (5.8 to 6.4), infant group 6.0 (5.7 to 6.3), P=0.99);(b) insulin concentration; (c) blood pressure; (d)lipid concentration; or (e) coagulation factors. Concentrations of von Willebrand factor were raised in the intrauterine group (156.5 (79.1 to 309.5)) compared with the infant group (127.6 (63.9 to 254.8); P
