Abstract

Background: Puberty is the transition from childhood to adulthood, and nowadays, early puberty is particularly prevalent among girls. Early puberty can affect the psychological and intellectual development of children. Objectives: This study aims to 1) determine the prevalence of puberty among female middle school students in Can Tho City; and 2) investigate factors associated with puberty before the age of 11 among female middle school students in Can Tho City. Subjects and Methods: A descriptive cross-sectional study with statistical analysis was conducted on 971 female middle school students in Can Tho City in 2022. Results: Among the 971 students studied, the rate of puberty was 86%, with an average age of puberty onset at 11.29 years, and 21.9% experienced puberty before the age of 11. Factors associated with early puberty before age 11 include belonging to an ethnic minority other than the Kinh majority, living in economically better-off urban areas, residing in multi-story houses, and having a birth weight between 2500-3500 grams (p<0.05).
