Few studies have explored the content of colostrum from women with Type 1 diabetes.Research AimsThis study aimed to investigate the macronutrients in colostrum collected during pregnancy and in the early postpartum period to compare colostrum contents in women with and without Type 1 diabetes.MethodsIn this cohort study, we collected colostrum among 20 women, 10 with and 10 without Type 1 diabetes, at 10 different time points in gestational weeks 36-40 and postpartum Days 1-5. We measured carbohydrates, protein, fat, and kilocalories in colostrum using a human milk analyzer; and we analyzed data using linear mixed models. In a follow-up analysis, we compared the content of colostrum from Day 1 with the nutritional values provided on the commercial milk formula, using a one-sample <i>t</i> test.ResultsThere were no mean differences in carbohydrates (6.6 g/100 ml; 95% CI [6.3, 6.9] vs. 6.7 g/100 ml; 95% CI [6.4, 7.0] <i>p</i> = 0.29); kilocalories (71.1 kcal/100 ml; 95% CI [62.9, 79.3] vs. 85.3 kcal/100 ml; 95% CI [77.2, 93.3] <i>p</i> = 0.21], and fat (2.7 g/100 ml; 95% CI [1.8, 3.6] vs. 2.3 g/100 ml; 95% CI [1.4, 3.2] <i>p</i> = 0.55) in colostrum when comparing women with and without Type 1 diabetes.
