    Background/Objectives: Chrononutrition is an emergent field concerning the effect of eating patterns on human health and their relationship with biological rhythms. Current evidence points towards the benefits of early eating in the prevention of non-communicable diseases and circadian health. Despite the importance of eating/fasting rhythm, current methods are neither specific nor validated against physiological variables. This work aimed to explore an objective metabolic outcome, postprandial glucose, as an accuracy indicator of self-declared meal schedules registered in a mobile app. Methods: A 1-week protocol of ambulatory monitoring of meal schedules, glucose, and circadian variables was performed in 20 young adults. Meal annotations were registered using KronoEat 1.0, a smartphone app, allowing for both prospective and recall entries. A circadian monitoring device provided data on movement intensity, distal skin temperature, and prospective food annotation. Results: Participants annotated an average of 3.5 food events/day/participant with KronoEat. Breakfast (92.7%) and lunch (86.4%) showed the highest proportion of food events related to a glycemic excursion, whereas this proportion was lower for dinner (79.7%) and snacks (67.7%). Postprandial glucose after main meals differed significantly from average glucose levels. Interesting couplings were found in circadian variables and glucose—for example, between post-breakfast glycemic excursions and the morning increase in activity. Conclusions: Meal schedules registered under free-living conditions in KronoEat show high levels of correlation with postprandial glucose and glycemic excursions derived from continuous glucose monitoring.

    Is low docosahexaenoic acid associated with disturbed rhythms and neurodevelopment in offsprings of diabetic mothers?

    BACKGROUND/OBJECTIVE: To evaluate the relation between docosahexaenoic acid (DHA) status and neurodevelopment in the offsprings of gestational diabetic mothers (ODMs). SUBJECTS/METHODS: A prospective cohort study was performed. The offspring of 63 pregnant women (23 controls, 21 diet-controlled gestational diabetes mellitus (GDM) and 19 insulin-treated GDM) were recruited. Maternal and venous cord plasma DHA percentages were analyzed. Skin temperature and activity in children were recorded for 72 h at 3 and 6 months of life. Neurodevelopment was assessed using the Bayley Scale of Infant Development II (BSID II) at 6 and 12 months of age. RESULTS: Cord plasma DHA percentage was significantly lower in the ODMs compared with that in the controls (Control 6.43 [5.04–7.82]a; GDM+diet 5.65 [4.44–6.86]ab; GDM+insulin 5.53 [4.45–6.61]b). Both mental (Control 102.71 [97.61–107.81]a; GDM+diet100.39 [91.43–109.35]a; GDM+insulin 93.94 [88.31–99.57]b) and psychomotor (Control 91.52 [81.82–101.22]a; GDM+diet 81.67[73.95–89.39]b; GDM+insulin 81.89 [71.96–91.85]b) scores evaluated by the BSID II were significantly lower at 6 months in ODMs, even after adjusting for confounding factors such as breastfeeding, maternal educational level and gender. Cord plasma DHA percentage correlated with the psychomotor score from BSID II (r = 0.27; P = 0.049) and with the intra-daily variability in activity (r = − 0.24; P = 0.043) at 6 months. Maternal DHA was correlated with several sleep rhythm maturation parameters at 6 months. CONCLUSIONS: Lower DHA levels in cord plasma of ODMs could affect their neurodevelopment. Maternal DHA status was also associated with higher values in the sleep rhythm maturation parameters of children.
