Article Abstract

Objective: We aim (1) to examine secular trends in height, weight, and waist circumference (WC) among Peruvian children and adolescents living in the city of Junín and (2) to compare their growth status with the World Health Organization (WHO) and US Centers for Disease Control and Prevention (CDC) reference data.

Methods: The sample included 2874 Peruvians (n = 1681 in the 2009 cohort and n = 1193 in the 2019 cohort) aged 6-16 years from the district of Junín (4107 m of altitude). Height, weight, and WC were measured using standardized protocols. Within each sex, a two-way between-subjects analysis of variance-age, and cohort as main factors and age-by-cohort as the interaction-was used to test for differences in height, weight, and WC. STATA 17 software was used in all statistical analyses.

Results: Height revealed a positive secular trend among girls, aged 6-11 years, and among boys up to 14 years of age. Similar positive secular trends in weight and WC were found across all age groups in both boys and girls. Compared to North American peers, children in the 2009 cohort were shorter, lighter, and had a smaller WC. For weight and WC, the 2019 cohort overlapped the 50th percentile across all age groups (except for 16-year-old girls).

Conclusions: Both boys' and girls' height, weight, and WC showed positive secular trends between 2009 and 2019, with statistically significant differences varying across age groups. Peruvian youth of both sexes were shorter and lighter than their North American peers.

BackgroundIn 2023, a collaborative UNICEF-WHO group introduced the concept of small vulnerable newborns (SVNs) to improve the identification of newborns at increased risk of adverse outcomes and to guide more effective preventive strategies. However, global data on the prevalence of SVNs remains scarce. This study aimed to examine secular trends in the prevalence of SVNs and their three subgroups, namely term small for gestational age (SGA), preterm SGA, and preterm non-SGA, in the Japanese population.

Secular trends in children's physical development are important indicators of population health, nutritional status, and socioeconomic conditions. This study aimed to assess long-term changes in the height, weight, Body Mass Index (BMI), and nutritional status of boys from Eastern Poland between 1986 and 2021. Anthropometric data were collected from 13,172 boys aged 8, 13, and 17 years at five time points (1986, 1996, 2006, 2016, and 2021).

This study aims to assess the secular changes in height of Chinese rural children and adolescents aged 718 years from 1985 to 2019. Height data for Chinese children and adolescents aged 718 years were obtained from the Chinese National Surveillance on Students Constitution and Health in 1985, 1995, 2005, 2014 and 2019. All provinces were divided into eastern, central, and western regions of China.

Background: Hemodialysis-associated bloodstream infections (BSIs) represent a significant burden for patients. Understanding the trends in BSIs among hemodialysis patients is crucial for informing strategies to reduce their incidence and improve patient outcomes. This study aimed to evaluate secular trends, identify causative organisms, assess resistance patterns, and determine the sources of hemodialysis-associated BSIs at Geneva University Hospitals, where Staphylococcus aureus screening and decolonization of hemodialysis patients have been implemented since the year 2000.
