Stillbirth risk by fetal size among 126.5 million births in 15 countries from 2000 to 2020: A fetuses-at-risk approach.

Objective: To compare stillbirth rates and risks for small for gestational age (SGA), large for gestational age (LGA) and appropriate for gestational age (AGA) pregnancies at 24-44 completed weeks of gestation using a birth-based and fetuses-at-risk approachs.

Design: Population-based, multi-country study.

Setting: National data systems in 15 high- and middle-income countries.

Changes in Resources and Volunteering: A Longitudinal Study of Active Engagement Among Older Europeans.

Background And Objectives: Volunteering is an important dimension of successful aging. Although prior studies have found that personal resources such as health and financial situations are associated with volunteering, there is a lack of research exploring the relationship between resource changes and volunteering. Here, we investigated whether changes in individuals' resources were associated with volunteer engagement among older Europeans.

Stillbirths: Contribution of preterm birth and size-for-gestational age for 125.4 million total births from nationwide records in 13 countries, 2000-2020.

Objective: To examine the contribution of preterm birth and size-for-gestational age in stillbirths using six 'newborn types'.

Design: Population-based multi-country analyses.

Setting: Births collected through routine data systems in 13 countries.

Comparing the cognitive functioning of middle-aged and older foreign-origin population in Estonia to host and origin populations.

Background: In migration and health research, the healthy migrant effect has been a common finding, but it usually pertains to specific contexts only. Existing findings are inconsistent and inconclusive regarding the cognitive functioning of the (aging) foreign-origin population relative to the populations of their host and sending countries. Moreover, this comparison is an understudied design setting.
