Aim: Height velocity is considered a key auxological tool to monitor growth, but updated height velocity growth charts are lacking. We aimed to derive new French height velocity growth charts by using a big-data approach based on routine measurements., Methods: We extracted all growth data of children aged 1 month-18 years from the electronic medical records of 42 primary care physicians, between 1 January 1990 and 8 February 2018, throughout the French metropolitan territory. We derived annual and biannual height velocity growth charts until age 15 years by using the Lambda-Mu-Sigma method. These new growth charts were compared to the 1979 French and 2009 World Health Organisation (WHO) ones., Results: New height velocity growth charts were generated with 193 124 and 209 221 annual and biannual values from 80 204 and 87 260 children, respectively, and showed good internal fit. Median curves were close to the 1979 French or 2009 WHO ones, but SD curves displayed important differences. Similar results were found with the biannual height velocity growth charts., Conclusion: We produced new height velocity growth charts until age 15 years by using a big-data approach applied to measurements routinely collected in clinical practice. These updated growth charts could help optimise growth-monitoring performance., (© 2024 The Author(s). Acta Paediatrica published by John Wiley & Sons Ltd on behalf of Foundation Acta Paediatrica.)

Objectives: To describe the policies about parent visiting and involvement in care during admission to French PICUs., Design: A structured questionnaire was emailed to the chief of each of 35 French PICUs. Data about visiting policies, involvement in care, evolution of policies, and general characteristics were collected from April 2021 to May 2021. A descriptive analysis was conducted., Setting: Thirty-five PICUs in France., Patients: None., Interventions: None., Measurements and Main Results: Twenty-nine of 35 (83%) PICUs replied. Twenty-four-hour access for parents was reported for all PICUs responding. Other allowed visitors were grandparents (21/29, 72%) and siblings (19/29, 66%) with professional support. Simultaneous visits were restricted to two visitors in 83% (24/29) of PICUs. Family presence was always permitted during medical rounds for 20 of 29 (69%) PICUs. Most of the units rarely or never allowed parental presence during the most invasive procedures, such as central venous catheter placement (18/29, 62%) and intubation (22/29, 76%)., Conclusions: Unrestricted access to the PICU, for both parents, was available in all responding French units. There were, however, restrictions on the number of visitors and the presence of other family members at the bedside. Moreover, permission for parental presence during care procedures was heterogenous, and mainly restricted. National guidelines and educational programs are needed to support family wishes and promote acceptance by healthcare providers in French PICUs., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest., (Copyright © 2023 by the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies.)

Background: The monitoring of head circumference (HC) is essential to early detect any conditions affecting its growth in early childhood. A positive secular trend and regional specificities in HC suggested the need to provide updated national HC reference growth charts., Methods: We extracted all growth data collected from 42 primary-care physicians from across the French metropolitan territory who used the same electronic medical-records software. We selected HC measurements up to age five years for all children who were born after 1990 with birth weight > 2500 g. We derived new HC growth charts by using Generalized Additive Models for Location, Scale and Shape, then externally validated them until 30 months of age by comparison with the national population-based Étude Longitudinale Française depuis l'Enfance (ELFE) birth cohort and compared them to previous French and WHO growth charts., Findings: With 973,869 HC measurements from 157,762 children, new calibrated HC growth charts from birth to age five years were generated. The new HC growth charts showed good external fit by comparison with the ELFE birth cohort. As compared with the new HC growth charts, the previous French and WHO growth charts mean HC z-scores were, respectively, -0.4 and -0.6 SD for girls and -0.2 and -0.6 SD for boys., Interpretation: We produced and validated national calibrated HC growth charts by using a novel big-data approach applied to data routinely collected in clinical practice. Comparison with previous French and WHO growth charts confirmed a positive secular trend since the 1960s and regional specificities., Funding: The French Ministry of Health; Laboratoires Guigoz-General Pediatrics section of the French Society of Pediatrics-Paediatric Epidemiological Research Group; the French Association of Ambulatory Pediatrics; and educational grant from the Regional Health Agency of Ile-de-France., Competing Interests: BH, AW, MC, BF and PS are co-owners of the patent for the new national French AFPA/Inserm/CGM growth charts.
