Abstract

BACKGROUND

Menarcheal age is a sensitive indicator of environmental conditions during childhood. The aim of study is to determine the age at menarche and growth status in adolescents in a rural area of Tarka, Wannune, Nigeria.

METHODS

Data on 722 female students (aged 12-18 years) were collected in February 2009. Height and weight were measured. Body mass index (BMI; kg m-2) was used as an index of relative weight.

RESULTS

Mean and median menarcheal age calculated by probit analysis were 13.02 (SD 3.0) (95% CI: 13.02-13.07), and age 13.00 (SD 2.8) (95% CI: 12.98-13.04), respectively. Girls who reach menarche are significantly heavier and taller with higher BMIs than those of their pre-menarcheal peers.

CONCLUSION

The age of menarche is probably still declining in Nigeria. Although BMI is an important factor in the onset of menstruation, some other unmeasured environmental variables may be implicated in this population.

摘要

背景

初潮年龄是儿童期环境条件的敏感指标。本研究旨在确定尼日利亚万努内塔卡地区农村青少年的初潮年龄和生长状况。

方法

2009 年 2 月收集了 722 名女性学生(年龄在 12-18 岁之间)的数据。测量了身高和体重。体重指数(BMI;kg m-2)用作相对体重的指标。

结果

通过概率分析计算出的平均和中位数初潮年龄分别为 13.02(SD 3.0)(95%CI:13.02-13.07)和 13.00(SD 2.8)(95%CI:12.98-13.04)。初潮的女孩比她们的初潮前同龄人明显更重、更高,BMI 也更高。

结论

在尼日利亚,初潮年龄可能仍在下降。虽然 BMI 是月经初潮的一个重要因素,但该人群中可能还涉及一些其他未测量的环境变量。
