It is now thought that the distribution of fats towards the gluteofemoral region tend to be more plausible 8,9, Menstrual cycle is controlled by hormones and other factors influence its lengths and regularity 14and have a direct implication for women's fecundability and risk of hormonally associated diseases This study was designed to investigate if there are differences in the anthropometric and menstrual characteristics of girls from Nigeria and Niger Republic.

Methodology Subjects This study was based on a cross-sectional sample of female subjects who are students of the Ahmadu Bello University, Zaria. The method involved administering questionnaires for the collection of demographic data age, birth weight and nationalityand direct measurements of weight, height, chest, waist and hip circumference and menstrual status menarcheal age, menstrual cycle, menstrual bleeding and prevalence of menstrual disorders.

Anthropometry Measurements were taken as follows: Height was measured to the nearest 0. Waist chest, hip, thigh, forearm and arm circumferences were taken with the subject standing, the waist circumference was measured at the minimal abdominal girth approximately midway between the xiphoid process and the umbilicus. Hip circumference was measured at the level of the greatest protrusion of the gluteal muscle.

All circumference measurements were carried out using nonflexible tape. The questionnaire contained questions on the pattern of menstrual flow, menarcheal age, menstrual disorders such as menorrhagia, Mittleschemerz, amenorrhea and parameters constituting pre-menstrual syndrome as described by Antai et al Significant difference in prevalence of premenstrual syndrome was checked using Chi-square analysis. The differences were accepted as significant when P Results Descriptive statistics of the anthropometric characteristics of the subjects is shown in Table 1.

The result showed that birth weight, thigh circumference and BMI significantly differed between the population P The mean and standard deviation of menstrual characteristics of the two populations are shown in Table 2.

For all other anthropometric variables Nigerian girls had higher values than girls from Niger Republic, except the hip circumference where girls from Niger Republic had higher value. Table 3 shows the incidence of menstrual disorders and their occurrences in Nigerian and Nigerien girls.

Only amenorrhea showed significant difference in the prevalence P The prevalence of premenstrual syndrome in both populations is shown in Table 4. Significance association were observed in backache, tiredness and headache in girls from Niger Republic P Figure 1 Table 1: Menstrual disorders in Nigerian and Nigerien girls.

Figure 4 Table 4: Prevalence of Premenstrual Syndrome in Nigerian and Nigerien Girls Discussion Our results have characteristically demonstrated that anthropometric traits of girls from Nigeria are higher than that of girls from Niger Republic with BMI and thigh circumference reaching significant differences.

To the best of our knowledge this is the first report comparing such traits between to the two countries. Difference in anthropometric and menstrual traits across populations has been attributed to nutritional status and invariably a reflection of the socioeconomic status of that population A recent report by Lessek and Gaulin 10 has attributed early age of menarche to the nature of fat distribution rather than the earlier theory of critical weight proposed by Frisch and Arthur It could be drawn from that the early menarcheal age in girls from Nigeria may be due to this phenomenon.

Significant difference were noted in BMI and thigh circumference of the two groups with girls from Nigeria being higher than girls from Niger Republic, this also agrees with the findings of Lessek and Gaulin 10 in America were girls with menarche significantly differ in gluteofemoral fat. Even though, there are myriads causes of amenorrhea which include anatomic defects, primary hypogonadism, hypothalamic causes, pituitary causes and other endocrine disorders 21from the present study it seems the major cause of the high prevalence of amenorrhea among the Nigerien subjects compared to the Nigerian subjects is hypothalamic in origin.

This hypothalamic cause may be possibly due to higher degree of stress and poor nutrition, but this claim needs further probing. The prevalence and pattern of premenstrual syndrome observed in he present study is lower than the prevalence reported by Antai et al 16 on a sample of students from the University of Calabar.

Further is similarity and dissimilarity in the pattern. The result of the Nigerian and Nigerien girls are more comparable than the results from Antai et al Conclusion This study has shown using anthropometric and menstrual parameters that girls from Nigeria would have more reproductive success than girls from Niger Republic.

This may be due to the fact that the Nigerien girls are more exposed to higher level of stress factors which could be environmental, nutritional, psychological or socio-economical when compared to Nigerian girls.
