It is known that a larger number of blood glucose control, glycemic control of patients with type 1 Dm suffers improvement. Likewise, the presence of hypoglycaemias maintained, especially at night and in school-age patients, could have a significant influence on neurological aspects such as night rest, learning and memory. Improved technology has id allowed or development of control devices interstitial glucose, both blinded (retrospective) as erta abi (real time). The free FREE STYLE device is one of the most widely used in our environment because it is in the Services Portfolio since the end of 2017.

Objective: To assess the impact of nocturnal hypoglycaemias on the final school performance of adolescents affected by type 1a DM by studying the periods of hypoglycemia recorded through the use of FREESTYLE.

Methods: DM1 children over 12 years in secondary school, with at least 6 months duration from the debut. Use of free FREESTYLE system> 85% of the study period. Prospective longitudinal follow-up. Rating or f time hypoglycemia (blood glucose <70 md / dl) from March to June 2018; analiz ando schedule period 8:00 p.m. to 8:00 am; and the average scores reached at the end of the course (1-10) in core subjects (language, mathematics, environmental knowledge, social, English) Comparative study .IBM SPSS Stastistics 19.0., Paired nonparametric samples n <30. Survey of Health Questionnaire SF-36 (Spanish and summary).

Results: 25 children (17♂), 1 course repeater, average age 14.5 to [12-17 .5]. Needs: 1.1 IU / kg / day [0.88-1.56], sensitivity 58 mgr / dl / IU [25-102] H bA1c (DCA): 7.7% [6.8-9.2] p: 0.38, Events of hypoglycemia / month 4, 9 [3-8] Hyperglycaemia events / month 8 [7-20]. Night study hours 38% hyper (> 180 mgr / dl) in normo 44% (70-180 mgr / dl and 18% in hiccups (<70 mgr / dl) Average grade study 7.25 If you select those patients who spend on average> 33% of the night shift in hypoglycemia, they are 8/25 cases The distribution denotes average for this group of 6.6 vs 8.1 p: 0.02 95% IC
