The change in single mothers’ educational gradient over time in Spain

Partnership, living arrangements, and low birth weight: evidence from a population-based study on Spanish mothers

BACKGROUND

Birth weight is considered a crucial indicator of individual and population health, as it determines a newborn's growth and development. An extensive body of research has explored various determinants of perinatal health, including the impact of living arrangements. This population-based study analyzes the relationship between mothers' partnership status and household structure and children's low birth weights. It addresses two basic research objectives: on one hand, how living/not living in a couple affects birth weight; on the other, how partnership status impact on birthweight when mothers live in extended households with other non-nuclear members.

METHODS

A novel database provided by the Spanish Office for National Statistics (INE), which links the 2011 census with births registered from 2011 to 2015 (sample size 22,433) is used. Llogistic regression models are estimated tto obtain adjusted odds ratios (OR) for the relative effects of living arrangements and other covariates such as characteristics of births and mothers' socioeconomic profiles, on birth weight.

RESULTS

Differences in low-birth-weight rates may be attributed to the dissimilar socio-demographic characteristics of the groups of mothers in the different coresidential situations. Although our models revealed that the impact of the covariates on birth weight was similar to that shown by previous studies, this was not the case for the effect of the main explanatory variable. Contrary to expectations, the presence/absence of a male partner in nuclear or in extended households does not reveal significant protection against low birth weight. Children born in households in which the male partner was absent were not more likely to have a low birth weight. On the other hand, analyzing the possible protective effect of extended households, we did not detect significant differences in the likelihood of low birth weight between single mothers without and with non-nuclear coresidents in their households.

CONCLUSIONS

Our analysis provides novel evidence regarding the effect of partnership status and household type on perinatal health in Spain. First, contrary to what has been observed in previous studies in Spain and elsewhere, our study shows that living without a partner has no effect on low birth weight. Second, we reveal that households including non-nuclear coresidents are associated with low birth weight suggesting that even in a basically familist societal context such as the Spanish one, the extended family does not fully protect against poor perinatal outcomes.

Single-Parent Families, Educational Gradient, and Child Deprivation: The Cases of Italy and Spain

This work examines whether the increase of single parenthood in Italy and Spain, specifically amongst women in an unfavourable socioeconomic position, has repercussions for child well-being, understood here as material deprivation. In particular, our main objective is to analyse the possible differential impact of single parenthood on children's material deprivation in relation to mothers' level of education. Using the 2014 EU-SILC Module on material deprivation, we identify five areas of child deprivation based on the EU-MODA approach: nutrition, clothing, education, leisure, and social life. In the case of Italy, our main results indicate that, compared to children from two-parent households, children of single mothers with a low level of education have a higher risk of nutrition and clothing deprivation. In Spain, living in a single-parent household is associated with a higher risk of deprivation in terms of social life for those children whose mothers do not have a high level of education. Therefore, the findings suggest that in both countries the growth of single parenthood amongst women with a lower educational level may have an impact on child well-being inequality. This article contributes empirical data to the growing literature on the rise of child poverty in Southern European countries.

The Demography of Families: A Review of Patterns and Change

The authors review demographic trends and research on families in the United States, with a special focus on the past decade. They consider the following several topics: (a) marriage and remarriage, (b) divorce, (c) cohabitation, (d) fertility, (e) same-gender unions, (f) immigrant families, and (g) children's living arrangements. Throughout, the authors review both overall trends and patterns as well as those by social class and race-ethnicity. The authors discuss major strands of recent research, emphasizing emerging themes and promising directions. They close with a summary of central patterns and trends and conclude that recent trends are not as uniform as they tended to be in earlier decades, making the description of family change increasingly complex.
