The rise in one-person households is one of the most significant sociodemographic phenomena Western societies have undergone since the mid-twentieth century. It is a phenomenon of particular interest in societies where family has traditionally held an important role in determining living arrangements. In Spain, only 4.1% of the population lived alone in 1991 while currently such percentage is more than 10% and approximately one in four homes are one-person households. This study analyses the process of generational replacement of these households taking into consideration four sociodemographic variables: age, sex, marital status and level of education. The influence of these variables, together with labour status, on solo-living is examined between 1991 and 2011 by applying demographic analysis and multivariate logistic regression models to census microdata samples from the Spanish National Institute of Statistics. Results show an inter-generational increase in solo living, affecting all age groups, as well as a diversification of the demographic profile of solo dwellers in Spain over the last three decades. This trend did not interrupt during the economic recession although being employed increased the probability of living alone invariably. Other factors contributing to a higher probability of living alone were being man and having higher education level (particularly among women). We find notable changes in the sociological profile of these households: an increase in the relative weight of young solo-dwellers and a drop in the weight of widowhood in favour of singlehood. These results are discussed in the context of the social changes that Spain has undergone [ABSTRACT FROM AUTHOR]

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.

This paper analyzes two possible determinants of disability, birth cohort and socioeconomic status, among Spanish elderly aged 65-89 living independently. We use microdata from the Spanish Health Interview Survey, particularly the self-reported ability to perform daily activities, to construct a continuous measure of disability. Multivariate linear regression models are applied separately for men and women controlling for the following variables: age, birth cohort, educational attainment and self-reported height. Results indicate stability in disability levels across successive generations as well as the existence of a socioeconomic dimension of disability especially among women and within ages 70-79.

Background: Applying sexual stature dimorphism (SSD) to history and the social sciences faces the difficulty of disentangling nature from nurture in addition to the limitations of sources (e.g. small, fragmented or heterogeneous samples). Aim: To investigate the relationship between inter-generational changes and social differences in SSD and the evolution of living conditions in 20th-century Spain. Subjects and methods: Self-reported height and socio-demographic information from individuals born 1910-1979 ( n = 99 023) were drawn from health interview surveys. Weighed least squares regression was used to construct continuous time-cohort series of SSD for the entire population and for specific socioeconomic groups represented by levels of educational attainment. Results: SSD remained below modern values among cohorts that were exposed to structural deprivation at pre-adult ages. Socioeconomic status mediated the correction of these deviations among subsequent cohorts. Lower classes (less educated segments of the population) systematically deviated to a greater extent from normal modern SSD values and they reached these values later in time. Conclusions: In Spain, variations in SSD have been found that are associated with both socioeconomic changes at a nationwide level and SES differentials at the individual level, thus continuous series of this indicator offer new opportunities in the study of living conditions of current and past generations.

Abstract: This paper seeks new insights concerning the health transition in 20th century Spain by analyzing both traditional (mortality-based) and alternative (anthropometric-based) health indicators. Data were drawn from national censuses, vital and cause-of-death statistics and seven National Health Surveys dating from 1987 to 2006 (almost 100,000 subjects aged 20–79 were used to compute cohort height averages). A multivariate regression analysis was performed on infant mortality and economic/historical dummy variables. Our results agree with the general timing of the health transition process in Spain as has been described to date insofar as we document that there was a rapid improvement of sanitary and health care related factors during the second half of the 20th century reflected by a steady decline in infant mortality and increase in adult height. However, the association between adult height and infant mortality turned out to be not linear. In addition, remarkable gender differences emerged: mean height increased continuously for male cohorts born after 1940 but meaningful improvements in height among female cohorts was not attained until the late 1950s.

Excess weight is becoming widespread in Spain due to changes in nutritional habits and lifestyles. Previous studies on this issue have focused on specific Spanish regions, subpopulations or relatively short time spans. This study analysed sex, age and cohort trends in the prevalence of adult overweight and obesity over the last two decades by applying a demographic methodology. Data came from the Spanish National Health Surveys that were held between 1987 and 2006. The respondent's demographic characteristics and self-reported height and weight were aggregated to a single dataset in order to analyse changes in weight and BMI by age and sex, over time and within and between quasi birth-cohorts. After correcting for sample bias and coding errors a total sample of about 100,000 subjects aged 20-79 was obtained. The results show that between 1987 and 2006 adult males and females increased their average weight by 8.2% and 2.8%, respectively. While among younger adults this is partly explained by height increases, prevalence in excess weight increased among 50- to 79-year-old males. Persons of the same 10-year age group but of a more recent 10-year quasi birth-cohort had a BMI that was 0.2-0.8 points higher. BMI increases were lower for women and mainly affected 60-79 year olds. In fact, even decreases were observed for 40- to 49 and 50- to 59-year-old women. Potential explanatory factors are discussed. [ABSTRACT FROM AUTHOR]

The article examines the long-term trends in stature in rural Eastern Andalusia based on data of height from adult males between the 18th century and 20th century. Time-cohort series and general trends were analyzed to compare average height with demographic and socioeconomic information to provide a basis for the potential interaction of variables. The possible implications of nutritional status shifts in social terms were considered. Results suggest a successive cycle of height variations until the mid-19th century. Institutional measures that may have interrupted the reproductive strategies of a significant portion of the rural population are discussed.

This article aims to assess the impact of autarchic policies on the biological dimensions of human well-being during Francoist regime in Spain. This is done by examining the nutritional status of the population through the study of male adult heights. Our case study is the Valencian Community with the focus on the period 1940–59 which witnessed the implementation of such policies. The heights of 21-year old draftees born between 1900 and 1954 from nine municipalities (N = 87,510) were analyzed in the light of inter-cohort deviations from a secular trend established for cohorts that were not exposed to autarchy-related hardships. Height was regressed on infant mortality as a way to control for infection and therefore approach the net effect of nutrition on height outcomes. Contrarily to what was displayed by cohort height trends in themselves, the results reveal a significant worsening of the nutritional status of the male population at the time. Deviations from the expected height trend across municipalities ranged between −0.5 and −3.4 mm per year. The effects of malnutrition are found to be larger among cohorts born in the period 1920–34 in coherence with a longer exposure to autarchy hardships during adolescence. Pre-autarchy nutrition levels observed among the cohorts of 1900–14 were not regained until the cohorts 1945–49. The results also show that malnutrition had an unequal impact with the large industrial towns of our sample experiencing the poorest height outcomes. Overall, these results invite to revise conclusions obtained from the sole evidence of height trends and they question the efficiency of intervention policies implemented in Spain during the 1940s. • Height trends must be interpreted as a function of the total burden of cohort exposure. • Height deviations help to assess the impact of environmental stress on nutritional status. • Over 90% of height deviations observed is associated with exposure to autarchy. • The effects of autarchy policies were larger among cohorts exposed during adolescence. • Nutrition levels observed among cohorts 1900–14 were not regained until 1945-49.
