Height and puberty in contemporary healthy Eastern Nigerian growing children: a clinical anthropological study.

This is a cross-sectional study of the growth curve for contemporary Nigerian children living in Port Harcourt. 2800 children between the ages of 3 and 18 were used for the study; they were divided into low and high socioeconomic class. The results indicate that height values for this group of children compare favorably with the World Health Organization (WHO) standards. There is no conclusive evidence that the children of low socioeconomic class attained puberty later than children of high socioeconomic class. Although the acceleration is faster in the high class group the average height attained at puberty is similar for both boys and girls. The age of puberty was also determined from cross-sectional analysis to be 17 years for male and 15 years for female children. When height is used together with other clinically important anthropometric parameters like surface area mid-arm circumference and weight it has a wide range of utility in preventive and diagnostic clinical work. Normal values of heights are subject to secular changes and must be re-evaluated from time to time.
