Secular Changes in Growth in the Maya Village of Yalcoba: 1986-2023.

Objective: To analyze the changes in children's height, weight, BMI and rates of stunting and overweight and obesity over three periods: 1986-1987, 1996-1998, and 2023 for the community of Yalcoba in the Yucatan Peninsula.

Material And Methods: Four hundred forty (6-to-15 years) children measured in 2023 were compared with data obtained in 1986-1987 (n = 675) and 1996-1998 (n = 628). Z-scores of height and BMI were calculated to estimate percentages of stunting and high BMI-for-age (overweight and obesity).

Secular trends in the anthropometric characteristics of children in a rural community in Yucatan, Mexico.

Objective: To analyze changes in height, weight, and body mass index (BMI = kg/m ) from 1986 to 2022 in 3-11 year old children from Dzeal, a rural Maya community in Yucatan, Mexico.
