“…This confirms that children from the canton of Zurich are on average taller than the WHO reference population [34]. Previous studies reported a slightly higher age of peak height growth in Switzerland (13.9 years for males; 12.2 years for females) than the UK (13.6 years for males; 11.7 years for females), Canada (13.4 years for males; 11.8 years for females), and the United States (13 years for males, 11 years for females) [35][36][37].…”

BackgroundReferences from the Global Lung Function Initiative (GLI) are widely used to interpret children's spirometry results. We assessed fit for healthy schoolchildren.MethodsLuftiBus in the school (LUIS) is a population-based cross-sectional study done from 2013–2016 in the canton of Zurich, Switzerland. Parents and children aged 6–17 years answered questionnaires about respiratory symptoms and lifestyle. Children underwent spirometry in a mobile lung function lab. We calculated GLI-based z-scores for FEV1, FVC, FEV1/FVC, and FEF25–75 for healthy White participants. We defined appropriate fit to GLI references by mean values between+0.5 and −0.5 z-scores. We assessed if fit varied by age, body mass index, height, and sex using linear regression models.ResultsWe analysed data from 2036 children with valid FEV1 measurements of which 1762 also had valid FVC measurements. The median age was 12.2 years. Fit was appropriate for children aged 6–11 years for all indices. In adolescents aged 12–17 years, fit was appropriate for FEV1/FVC (mean: −0.09; sd: 1.02) z-scores, but not for FEV1 (mean: −0.62; sd: 0.98), FVC (mean: −0.60; sd: 0.98), and FEF25–75 (mean: −0.54; sd: 1.02). FEV1, FVC, and FEF25–75 z-scores fitted better in children considered overweight (means: −0.25, −0.13, −0.38) than normal weight (means: −0.55, −0.50, −0.55; p-trend: <0.001, 0.014, <0.001). FEV1, FVC, and FEF25–75 z-scores depended on both age and height (p-interaction: 0.034, 0.019, <0.01).ConclusionGLI-based FEV1, FVC, and FEF25–75 z-scores do not fit White Swiss adolescents well. This should be considered when using reference equations for clinical decision making, research and international comparison.

“…Fellows will need to understand growth, dietary intake, and physical activity patterns/capacity from a developmental perspective. For example, peak times for growth (height and weight) occur during the first 2 years of life (Wilmore & Costill, 1994) and then during adolescence (Abbassi, 1998). For dietary intake, developmental variations in growth affect caloric needs and help to guide prevention and intervention strategies.…”

Pediatric obesity is a complex condition in which psychologists play an important role in the interprofessional treatment team. Building upon graduate school practicum and internship training, the postdoctoral year offers an opportunity to obtain specialized training. This paper highlights the main training areas for psychology postdoctoral fellows interested in specializing in pediatric weight management. The American Psychological Association Benchmarks are used as a framework for highlighting main training issues relevant to working with pediatric patients with obesity focusing on (a) individual and cultural diversity, (b) ethical legal standards and policy, (c) reflective practice, (d) scientific knowledge and methods, (e) intervention and assessment, and (f) interdisciplinary systems. Although various training areas are addressed, the increasing need for psychologists to integrate themselves into medical settings underscores the need for expertise across all of these areas and applied to interprofessional collaborations.

“…The most recognizable physical and biological signs during puberty are statural growth (approximately 20% of adult stature matures during puberty) and the acquisition of secondary sexual characteristics [19]. The most widely employed staging system is that of sexual maturity assessments, also referred to as "Tanner stages", initially proposed by Marshall and Tanner [20,21].…”

Puberty is a critical phase of growth and development characterized by a complex process regulated by the neuroendocrine system. Precocious puberty (PP) is defined as the appearance of physical and hormonal signs of pubertal development at an earlier age than is considered normal. The timing of puberty has important public health, clinical, and social implications. In fact, it is crucial in psychological and physical development and can impact future health. Nutritional status is considered as one of the most important factors modulating pubertal development. This narrative review presents an overview on the role of nutritional factors as determinants of the timing of sexual maturation, focusing on early-life and childhood nutrition. As reported, breast milk seems to have an important protective role against early puberty onset, mainly due to its positive influence on infant growth rate and childhood overweight prevention. The energy imbalance, macro/micronutrient food content, and dietary patterns may modulate the premature activation of the hypothalamic–pituitary–gonadal axis, inducing precocious activation of puberty. An increase in knowledge on the mechanism whereby nutrients may influence puberty will be useful in providing adequate nutritional recommendations to prevent PP and related complications.
