Intergenerational transmission of dietary habits among Italian children and adolescents.

The aim of this paper is to investigate the relationship between parental dietary habits and child and adolescent diet quality in Italy by adopting a parent-child perspective. We apply quantile regression modelling to an original database developed within the DEDIPAC knowledge hub, integrating multiple sources of information on the aspects of Italian households' daily lives, food consumption frequency, and calorie intake. Given the relevance of maternal care in shaping children's eating patterns, we focus on mothers' lifestyles and time-use. Results show that the intergenerational transmission of diet quality is a gendered process, especially involving mothers and their daughters. Our findings also highlight the pivotal role schools play in the fight against child malnutrition and indicate that, contrary to what is found in the international research literature, maternal employment is not correlated with a deterioration in their children's diet quality.

The human sex ratio at birth and late fetal mortality: the Italian case.

This study explores the short-term relationships between sex ratio at birth and late fetal mortality in Italy from 1910 to 2016. As the leading scholars' attention traditionally focused on long-term trends and variations in the sex ratios at birth among different populations, less interest regarded short-term fluctuations as they were mainly seen as an effect of random variability. We detrended the national series of males proportion among live births and stillbirths by their medium-term component to consider the annual deviations from a normal trend. After controlling for fertility tendencies and wars effects, regression models seem to show the effects of stillbirth on the proportion of male newborns. A sensitivity analysis was also carried out to assess the effects of the perinatal deaths on the proportion of males at birth, combining stillbirths and early neonatal losses to control the possible misspecification between stillborn infants and early neonatal deaths. The significance of late fetal mortality reflects the mortality excess among male fetuses during the intrauterine life, showing evidence for the in utero hypothesis selection.

Reproductive behavior during the pre-transitional period: evidence from rural Bologna.

A longitudinal, micro-level study of the effect of socioeconomic transformations on fertility mechanisms in the rural hinterland of Bologna between 1818 and 1900 (the beginning of the demographic transition) demonstrates that the premature death of a last-born child reduces the interval between two consecutive childbirths. Thus does it confirm the importance of breast-feeding in determining birth spacing. Women living in complex sharecropping households experienced a significantly higher risk of childbirth than did women in families headed by daily wage earners. In addition, the reproductive behavior of sharecroppers seemed to be substantially invariant to short-term ºuctuations in prices, whereas the laborers' group experienced a negative price effect. Both descriptive and multivariate analyses indicate a slight and gradual decrease in fertility levels during the period in question.
