“…Close association between the trends and industrialization, perhaps a unique phenomenon so characteristic in many developing countries during the later 20th century, were found (Hwang et al, 2003;Lopez, 1995;Malina et al, 2004;Papadimitriou et al, 2002). Socioeconomic factors act through biological factors to influence physical growth.…”

Evidence shows a secular trend in physical growth in China in recent years. We analyze the secular trend of stature and body mass index (BMI) for the period 1950s-2005 to provide biological evidence for policy-makers to identify measures for improving Chinese children's health. Data come from the historical records in 1950s and the successive cycles of the Chinese National Survey on Student's Constitution and Health. Subjects were 7- to 18-year-old youth from 16 cities. Sex-age differences in mean stature and BMI values between the surveys were analyzed, and the increments per decade were compared. An overall positive secular trend was found in 1950s-2005. Mean stature of the 18-year olds increased from 166.6 to 173.4 cm for males and from 155.8 to 161.2 cm for females, yielding rates of 1.3 and 1.1 cm/decade; the overall increments of BMI values were 2.6 for males and 1.8 for females, yielding rates of 0.8 and 0.6/decade, respectively. The most significant changes occurred during puberty. The overall positive secular trend is closely associated with the socioeconomic progress and the improvement of livelihood. Strong evidence suggests that in China this trend will be continued for many years. Further studies are needed to explore how to ensure healthy changes for poorer rural youth. Effective preventive strategies and measures should be taken to prevent the progressive increase in the prevalence of childhood obesity accompanying this trend.

“…18 The evidence is that in a given population, positive changes in height may cease if there is no further improvement in the environmental conditions and/ or if the population reaches its genetic growth potential. 19 Furthermore, growth is mainly achieved during childhood, the traditionally higher growth rate during adolescence having diminished in populations in which the secular increase in tempo of growth has slowed down or stopped. 20 Data on secular changes in African populations are quite scarce and mainly concern Southern Africans during the first fifty years of the last century.…”

ObjecTIVe: The aim of this study was to investigate whether a secular trend in growth occurred during the last century in Pygmies from cameroon (West Pygmies) and in bantu rural farmers, the latter being studied to serve as controls. DeSIgn: The evolution in height of West Pygmies and bantu farmers from 1911 to 2006 was evaluated using data from the literature as well as data gathered by our research team during an expedition to cameroon in 2006. ReSUlTS: During the last century, no secular trend in west Pygmies is apparent, as height changed from 151 cm to 155 cm in males and from 143 cm to 146 cm in females. A small though significant (p=0.026), increment (about 2 cm) was observed only in female subjects during the last ten years. by contrast, bantu heights show a significant change from 1943 to 2006 for both males (from 159 cm to 172 cm; p=0.025) and females (from 148 cm to 160 cm; p=0.029). cOnclUSIOnS: Over the last century, the bantu population exhibited a significant secular trend for height, whereas West Pygmies did not increase their linear growth. The lack of secular trend in Pygmies possibly suggests that their stature reflects adaptation to the forest lifestyle. We may hypothesize that not only environmental but epigenetic factors have also contributed to their growth potential.
