'Datta Banik S, Dickinson F, 2016: Comparison of height, body fatness and socioeconomic status between pre- and postmenarcheal girls 11 to 13 years of age in Merida, Yucatan. Anthropologie (Brno) 54, 2: 141-154'.
|Age at menarche (AAM) is a growth and development indicator in girls. A study compared height,
nutritional status and body fatness between premenarcheal and postmenarcheal girls (11 to 13 years old) from
Merida, Yucatan, in relation to socioeconomic status (SES). Height and weight were recorded for 212 girls (90
premenarcheal). Body fat (BF), dry lean mass (DLM) were estimated by bioelectrical impedance analyses. The SES
indicators included school type, parents' age, education, occupation, family structure, and mother's age at pregnancy.
Mean AAM was 11.21 years. Postmenarcheal girls were taller, had a lower frequency of stunting, and higher BMI,
BF (%), DLM than their premenarcheal age peers. A high frequency of excess weight (overweight plus obesity) was
noted among premenarcheal (37.77 %) and postmenarcheal (50.82 %) girls. Overweight prevalence was higher in
postmenarcheal girls but obesity was higher in premenarcheal girls. Excess weight was more frequent in early
menarche (AAM <12 years) girls (52.70 %) than not early menarche (AMM >12 years) girls (47.92 %). Height, BF
(%), SES, mother's early menarche significantly predicted menarche (pre or post) of the girls.|
