Thus, it is relevant to identify modifiable risk factors of early menarche. Some nutrients and foods have been linked to pubertal timing, but how menarche relates to overall dietary patterns is unclear.<h4>Methods</h4>The aim of this study was to analyze the association between dietary patterns and age at menarche in a prospective cohort of Chilean girls from low and middle-income families. We conducted a survival analysis of 215 girls (median = 12.7 years, IQR = 12.2-13.2) from the Growth and Obesity Cohort Study (GOCS) who had been followed prospectively since 4 years of age (2006). Age at menarche and anthropometric measurements were recorded every 6 months since Frontiers in public health995593https://www.ebi.ac.uk/biostudies/studies/S-EPMC9922868biostudies-literatureLower adherence to a prudent dietary pattern is associated with earlier age at menarche in adolescents from the Growth and Obesity Chilean Cohort Study.PMC9922868Martinez-Arroyo ACorvalan CCantor EFisberg RMfalseLower adherence to a prudent dietary pattern is associated with earlier age at menarche in adolescents from the Growth and Obesity Chilean Cohort Study.<h4>Introduction</h4>Early menarche is associated with obesity, and metabolic and mental health risks, among other diseases.
