Deep phenotyping of pubertal development in Norwegian children
Ultrasound-based assessments of puberty provided novel references for breast developmental stages and enabled the measurement of testicular volume on a continuous scale. Endocrine z -scores allowed for an intuitive interpretation of changing hormonal levels during puberty on a quantitative scale, which, in turn, provides opportunities for further analysis of pubertal development using machine-learning approaches
Associations between different weight‐related anthropometric traits and lifestyle factors in Norwegian children and adolescents
OBJECTIVES: The purpose of this study was to investigate the association between weight-related anthropometric measures and children's eating habits, physical activity and sedentary lifestyle at a population level. METHODS: Data from the Bergen Growth Study were used to study the association of z-scores of waist circumference (WC), weight-to-height ratio (WHtR), subscapularis (SSF) and triceps (TSF) skinfolds and BMI, with lifestyle factors in 30…
BMI and BMI SDS in childhood
Background Early detection of abnormal weight gain in childhood may be important for preventive purposes. It is still debated which annual changes in BMI should warrant attention. Aim To analyse 1-year increments of Body Mass Index (BMI) and standardised BMI (BMI SDS) in childhood and explore conditional change in BMI SDS as an alternative method to evaluate 1-year changes in BMI. Subjects and methods The distributions of 1-year increments of BMI…
Interrelationships between anthropometric variables and overweight in childhood and adolescence
The interrelationships between BMI SDS and five standardized overweight related anthropometric variables were dependent on age, being weakest in the youngest age group. Independent of sex and age, WC SDS was in this study superior to other anthropometric variables in contributing to variation in BMI SDS during childhood
Growth references for 0–19 year-old Norwegian children for length/height, weight, body mass index and head circumference
Because of the observed secular trends in growth, it is advised to use the new references, which have been endorsed by the Norwegian Department of Health
The association between nutritional conditions during World War II and childhood anthropometric variables in the Nordic countries
The Nordic children were affected by WWII in terms of a transient reduction in temporal trends in height and weight, and the magnitude of this decrease was associated with the severity of the energy restriction prevailing in the respective country during the war. These findings warrant further studies of the chronic diseases associated with height and weight for cohorts being in their growth periods during WWII
