Updating normative cross-sectional values and secular trends in body mass, body height and body mass index among Quebec children and adolescents.

ABSTRACT:

Objective

The main objective of this study was to examine secular trends in body mass, body height and body mass index (BMI) from measured rather than self-reported values between 1972 and 2017.

Methods

A total of 4500 students (males = 51%) were selected from a stratified sampling. The age range varied between 6.0 and 17.9 years. The sample came from 24 elementary schools and 12 high schools located in six urban cities from the province of Québec. All the tests selected were based on standardized procedures that are recognized as valid and reliable. Standardization and modeling of smoothed percentile curves for each variable for both sexes were produced.

Results

Regional variations between youth from the province of Québec and those from all other Canadian provinces
