Is there an association between family members' season of birth that could influence birth seasonality? Evidence from Spain and France.

The number of births varies by season. Research on birth seasonality has shown that women's season of birth somehow influences that of their children, but factors underlying the intergenerational transmission of birth seasonality remain unknown. With data from Spain and France, we analysed the possibility of transmission of birth season between generations, testing whether relatives tended to be born in the same season.

Effect of emergency obstetric care and proximity to comprehensive facilities on facility-based delivery in Malawi and Haiti.

Proximity of households to comprehensive obstetric care is a key determinant for preventing maternal mortality due to obstetric emergencies. The relationship between proximity to comprehensive care and facility delivery is further complicated by the use of varied methods in measuring facility obstetric capacity-which may misrepresent the real scenario of obstetric care availability in a service environment. We investigated the joint effects of proximity and two emergency obstetric care assessment (EmOC) methods on women's place of delivery in Malawi and Haiti.

Adverse birth outcomes in New York City women: Revisiting the Hispanic Paradox.

In the United States, African American or non-Hispanic Black infants experienced worst birth outcomes whereas Hispanic and Asian infants have intermediate or similar outcomes compared with non-Hispanic white infants. The findings of better birth outcomes for Hispanic women have been coined the "Hispanic Paradox" given their low education, income, and access to care. New York City (NYC) has a great racial/ethnic diversity with implications for neighborhood racial/ethnic composition on birth outcomes by protecting women from psychosocial stress via social support that may buffer against racial/ethnic discrimination and/or racism.

Circulation and seasonality of influenza viruses in different transmission zones in Africa.

Background: Influenza is responsible for more than 5 million severe cases and 290,000 to 650,000 deaths every year worldwide. Developing countries account for 99% of influenza deaths in children under 5 years of age. This paper aimed to determine the dynamics of influenza viruses in African transmission areas to identify regional seasonality for appropriate decision-making and the development of regional preparedness and response strategies.

Influence of sociodemographic factors in birth seasonality in Spain.

Objectives: The goal of the present research is to establish for the first time a hierarchy of sociodemographic factors according to their importance influencing birth seasonality.

Methods: We used Vital Statistics data on all births registered in Spain in the period 2016-2019. Differences in the degree of seasonality between sociodemographic groups (defined by maternal age, maternal marital status, maternal education, birth order, maternal job qualification, maternal employment status, maternal location population size, and maternal country of birth) were first examined with descriptive techniques.
