Abstract
Objectives: This study aimed to assess the trend and factors associated with body fat percentage in 7- to 10-year-old schoolchildren in Florianópolis, Santa Catarina, Brazil, from 2002 to 2019.
Methods: This is a trend analysis of four cross-sectional surveys involving 6597 schoolchildren attending public and private schools. Body fat percentage (outcome variable) was calculated from triceps and subscapular skinfold thicknesses using Lohman equations and categorized into "no excess body fat" and "excess body fat." Sociodemographic and socioeconomic characteristics were also investigated. Trends and associated factors were analyzed using multivariate logistic regression.
Results: The prevalence of excess body fat was 22.6%, 25.5%, 37.5%, and 33.6% in 2002, 2007, 2013, and 2019, respectively, representing a 48.6% increase from 2002 to 2019. Schoolchildren assessed in 2013 (OR = 1.93) and 2019 (OR = 1.69), as well as those who were male (OR = 1.0) or older (9-10 years) (OR = 1.60), were more likely to have excess body fat.
Conclusions: The increasing trends of body fat percentage and excess body fat in 7- to 10-year-old schoolchildren from 2002 to 2019 underscore the need for targeted strategies to address the growing rates of childhood obesity, with particular attention to high-risk groups.
期刊介绍：
The American Journal of Human Biology is the Official Journal of the Human Biology Association.
The American Journal of Human Biology is a bimonthly, peer-reviewed, internationally circulated journal that publishes reports of original research, theoretical articles and timely reviews, and brief communications in the interdisciplinary field of human biology. As the official journal of the Human Biology Association, the Journal also publishes abstracts of research presented at its annual scientific meeting and book reviews relevant to the field.
The Journal seeks scholarly manuscripts that address all aspects of human biology, health, and disease, particularly those that stress comparative, developmental, ecological, or evolutionary perspectives. The transdisciplinary areas covered in the Journal include, but are not limited to, epidemiology, genetic variation, population biology and demography, physiology, anatomy, nutrition, growth and aging, physical performance, physical activity and fitness, ecology, and evolution, along with their interactions. The Journal publishes basic, applied, and methodologically oriented research from all areas, including measurement, analytical techniques and strategies, and computer applications in human biology.
Like many other biologically oriented disciplines, the field of human biology has undergone considerable growth and diversification in recent years, and the expansion of the aims and scope of the Journal is a reflection of this growth and membership diversification.
The Journal is committed to prompt review, and priority publication is given to manuscripts with novel or timely findings, and to manuscripts of unusual interest.
