8 % and very unhealthy, in 3.4 %. Girls had poorer scores in physical activity (p < 0.001), and boys, in new technologies, although it was not significant. The final instrument was valid, reliable, and easily administered to assess modifiable behaviors in adolescents. The inclusion of technologies and environment helps to adapt the questionnaire to current changes. The greatest deficit was observed in the technology use and physical activity domains; and girls were more sedentary.

From an infectious perspective, children and adolescents were not highly affected by the COVID-19 pandemic. However, social isolation measures have deeply changed their lifestyle, which is believed to have a psychological impact on them. The objective was to assess the impact of COVID-19 lockdown on the emotional health of children and adolescents attending primary or secondary school. Parents of children and adolescents from San Carlos de Bariloche participated in the study. Adults' perception of the emotional and behavioral impact of lockdown on children and adolescents, changes in sleeping habits, screen use, sports-related activities, eating, and medical consultations, was assessed. A total of 267 parents were included. Of them, 96.3 % noticed emotional and behavioral changes. The most common ones were that their children were more bored (76.8 %), more irritable (59.2 %), more reluctant (56.9 %), and angrier (54.7 %). It was observed that they woke up and went to bed later, and slept 30 minutes more. Moreover, leisure screen use increased by 3 hours on weekdays. Time dedicated to physical activities did not change, but the type of activities did swimming and team sports were replaced by biking, walking, and skiing. COVID-19 lockdown affected the emotional health and habits of children and adolescents. Boredom, irritability, and reluctance were more present during lockdown. The possibility of doing outdoor physical activities allowed them to keep practicing sports. COVID-19 lockdown affected the emotional health and habits of children and adolescents.

There is little evidence regarding the influence of emotional variables on breastfeeding among mothers of very low birth weight infants (VLBWIs). The objective of this study was to measure breast milk production (BMP) at two points in time during neonatal hospitalization and its association with anxiety, depression, and breastfeeding self-efficacy levels among mothers of VLBWIs. Prospective, observational, and multicenter study in mothers of VLBWIs (500-1500 g) from 9 NEOCOSUR Network centers. BMP was obtained by measuring the amount extracted by each mother. The STAI scale was used for anxiety, the BDI scale for depression, and the ALMA pilot scale for selfefficacy. They were administered at 14 days of life and at 36 weeks of postmenstrual age. The biosocial characteristics of mothers and neonates were also recorded. A total of 118 mothers participated. Mean BMP was 169 mL (standard deviation [SD] ± 132.4) at 14 days and 285 mL (SD ± 266.9) at 36 weeks, and it was significantly associated with the perception of breastfeeding self-efficacy (p < 0.001), which was maintained during hospitalization. There was a lower production trend among mothers with higher depression indices at 14 days of life, but not at 36 weeks. No association was observed between BMP and anxiety. No consistently significant associations were o
