Abstract
PURPOSE: Populations malnourished in early life are at increased risk for cardiometabolic diseases. We assessed if improved nutrition predicts cardiometabolic function, as assessed by postprandial biomarker responses. METHODS: Participants had been randomized at the village level to receive one of two nutritional supplements as children. At mean age 44 y (range 37-53 years), we obtained plasma samples before and 2 h after a mixed-component meal challenge. We assayed biomarkers including lipids, glycemic measurements, and inflammatory cytokines. We compared postprandial biomarker responses among those who received the improved nutrition intervention from conception through to their second birthday (the first 1000 days) to those with other exposure status, including those who received the improved nutrition intervention at other ages, and those who received the less nutritious supplement. RESULTS: Among 1027 participants (59.4% female), 22.9% were exposed to improved nutrition in the first 1000 days. Insulin increased the most in response to the meal challenge (over twofold), and non-esterified fatty acids decreased the most (by half). Glucose increased postprandial by 11.4% in the exposed group, compared with 15.7% in the other exposure group (p < 0.05), which remained significant after adjusting for confounders (- 4.7%; 95% confidence interval: - 9.3%, - 0.01%). Responses to the prandial challenges for the other biomarkers did not differ by intervention group (all p > 0.05). CONCLUSION: Early life exposure to improved nutrition was associated with a more favorable postprandial glucose response in this population. We did not observe a difference in overall cardiometabolic responses between the exposure groups.
