Introduction: height variations across cohorts are a proxy of the evolution of living conditions and, specifically, of the nutritional status of a given population. However, the interpretation of the changes in stature sexual dimorphism are controversial. Objective: to test the association between nutritional status and the changes in height differentials between men and women (sexual dimorphism) in the long run (19th and 20th centuries). Methods: three data sources containing measured adult heights are used, namely: -- Data from previous works. -- Data from health examination surveys in OECD countries. -- Data from the NCD RisC Factor Collaboration project. Two indicators are analyzed: absolute sexual dimorphism (men's height minus women's height) and the ratio of sexual dimorphism (men's height divided by women's height). Results: a secular trend of sexual dimorphism is evidenced over the second half of the 20th century coinciding with the substantial improvement of environmental factors that determine the net nutritional status. Among cohorts born at the end of the 20th century in non-marginal environments, the average sexual dimorphism was found to be 13.69 cm --absolute- and 1.084 --ratio-. In comparison with these modern figures of sexual dimorphism, those found among cohorts born during the 19th century are abnormally low, especially during periods of worsening of living conditions. Conclusions: if properly addressed, sexual dimorphism has the ability to report on the degree of environmental stress and its impact on the nutritional status and its differentials across specific groups of the population both cross-sectionally and over time.

Introduction: many studies have used anthropometric data to approach the evolution of the net nutritional status but those focused on its socioeconomic differentials over time are still a few in Spain. Objective: to analyze the evolution of nutritional inequalities in the long run by using a sample of male statures from the Spanish towns of Elche and Orihuela. Methods: we use anthropometric and sociodemographic data entailed to conscripts aged 19-21 who were born between 1840 and 1964 and were measured between 1860 and 1984. Anthropometric inequalities are approached by analyzing height percentiles series, variation coefficient series as well as height series by socio-educational status: literate, illiterate and students. Results: there is a solid association between low height averages (poor nutritional status) and more heterogeneous height distribution (higher inequality). The highest values of the variation coefficient as well as the larger differences by socio-educational status are found during the central decades of the 19th century and during the context of the Spanish Civil War and the first postwar decade. Conclusion: nutritional inequalities as reflected by heights decreased from very high levels prior to the nutrition and epidemiological transitions moderate levels during such transitions. Nevertheless, an increase in nutritional inequality is found among the cohorts born during the decade of the 1940s which were fully or partially raised during the advanced stage of the nutrition transition.

This article underlines the relevance of anthropometric history among the disciplines concerned with health and nutrition. The examination of changes on the nutritional status and inequality in Spain focused the 4th Anthropometric History Workshop held at the beginning of 2018 where 18 original contributions were presented and discussed. We first show the ability of human stature to approach the impact of socioeconomic processes and environmental changes on the nutritional status over the last centuries. Then it is proceeded to present the main contents and advances achieved in the workshop. The papers coped with diverse dimensions of inequality regarding nutritional health and its determinants since the end of the 18th century until 2015. Aside of height and weight at different ages, principally adult ones, others anthropometric indicators were analyzed such as sexual dimorphism and low weight at birth. The results illustrate the large prevalence of malnutrition and social inequality in past Spain. These problems persisted over a good part of the 20th century (i.e. stunting) and, they acquired a different nature since the 1980s as the increasing prevalence of overweight and obesity reveals. It is concluded that the determinants of nutritional status and health-related inequalities request multidimensional approaches and the dialogue between social sciences and biomedical sciences. Knowing about their dimensions in the past and their evolution over time provides a valuable basis in order to understand current problems in these areas and to address future public policies more adequately on childhood and adolescence.

Objective: To explore the regional pattern of nutritional status and its evolution between the middle of the 19th century and the beginning of the 20th century in Spain. This period precedes the nutrition transition and it was characterized by the high prevalence of malnutrition. Methods: We use anthropometric data (province-level height means) from conscription in 1858 y 1913 as well as province-level means of height and weight from a large examination held among 119,571 soldiers in 1903-1906. These data are used to construct anthropometric cartography and descriptive statistics. Results: The complexion of Spanish conscripts as indicated by height and weight measures was among the lowest in Europe prior to the nutrition transition in this country. Male average height increased only 1.43 cm between 1858 and 1913. During that period significant changes in the anthropometric geography occurred in Spain which established a nutritional polarity on the eve of the World War I (WWI): inner and Southern provinces exhibited higher incidence of malnutrition whereas provinces in the North and East of the country displayed anthropometric figures above the national average. Conclusion: Spatial inequalities of nutritional status in Spain as reflected by anthropometric polarity may be largely associated with environmental changes. Such changes are related to the modernization and industrialization processes in this country at the time that a relative backwardness (e.g. economic and technological), structural scarcity, occasional subsistence and high exposure to illness persisted. Our results underline the utility of anthropometric data to approach the living conditions of past population and the process of nutrition transition in particular . [ABSTRACT FROM AUTHOR]
