Any such effects are limited by the time grandparents share with their grandchildren. Changing child mortality rates, grandparental longevity, and childbearing patterns may have profoundly altered the length of grandparenthood across the demographic transition, but this has received little scientific attention. Using a genealogical dataset from Finland, we investigate changes in this shared time, from the late 18th to mid-20th century. We found the number of shared years between grandparents and grandchildren was low until roughly the onset of industrialisation in Finland, after which point shared time increased rapidly, from both the grandchild and grandparent perspectives. Understanding changing patterns in the opportunity for intergenerational transfers between grandparents and grandchildren has implications for several fields of study, including biology, demography, sociology, health studies, and economics.</p> Simon N.

Finland has experienced two periods of deep economic recessions within last 25 years, one in the early 1990s and the other during the Great Recession in the 2000s. This study analyzes fertility response to economic recession in Finland through total and gender specific unemployment between 1991 and 2015 with sub-regional data. The method of analysis is sub-region fixed effect regression. The changes in unemployment were associated with changes in fertility in Finland from 1991 to 2015. One percentage increase in unemployment reduced delivery rate by 0.13 percentages. The effect of unemployment on fertility was stronger during the Great recession than during the recession in the 1990s.</p> Heikki Hiilamo ##submission.copyrightStatement## 2017-12-15 2017-12-15 52 15 28 10.23979/fypr.65254 Mental Wellbeing and Self-reported Symptoms of Reproductive Tract Infections among Girls <p>This study examined the self-reported mental wellbeing among slum-dwelling adolescents in Western India and asked whether adolescent postmenarcheal girls’ mental wellbeing and self-reported symptoms suggestive of reproductive tract infections (RTIs) were associated. A sub-section of a cross-sectional personal interview survey among unmarried 10–18-year-old adolescents (n= 85) in a slum in the city of Nashik was analyzed. Logistic regression models were used to assess the associations between sociodemographic variables, physical health indicators, and adolescent postmenarcheal girls’ mental wellbeing. Nearly every other postmenarcheal girl reported having experienced symptoms suggestive of RTIs during the last twelve months. Adolescent postmenarcheal girls’ mental health and some aspects of somatic health appear to be closely interrelated. Understanding the relationship between adolescent mental wellbeing and reproductive health in low-income countries requires further investigation. Health service development in growing informal urban agglomerations in India and beyond should provide combined mental and reproductive health services for adolescents.</p> <p>&nbsp;</p> Sushama A.

This paper is the first to compare the two language groups with regard to the receipt of sickness allowance, which is an objective health measure that reflects a less severe poor health condition. Register-based data covering the years 1988-2011 are used. We estimate logistic regression models with generalized estimating equations to account for repeated observations at the individual level. We find that Swedish-speaking men have approximately 30 percent lower odds of receiving sickness allowance than Finnish-speaking men, whereas the difference in women is about 15 percent. In correspondence with previous research on all-cause mortality at working ages, we find no language-group difference in sickness allowance receipt in the socially most successful subgroup of the population.</p> Kaarina S.

A register created during 1960s and published as a book series ‘Siirtokarjalaisten tie’ in 1970 documented the lives of individuals who fled the southern Karelian district of Finland after its first and second occupation by the Soviet Union in 1940 and 1944. To realize the potential value of these data for scientific research, we have recently scanned the register using optical character recognition (OCR) software, and developed proprietary computer code to extract these data. Here we outline the steps involved in the digitization process, and present an overview of the Migration Karelia (MiKARELIA) database now available to researchers. The digitized register contains over 160000 adults and a wide range of data on births, marriages, occupations and movements of these forced migrants, likely to be of interest to researchers across disciplines including demographers, anthropologists, evolutionary biologists, historians, economists and sociologists.</p> <p><em>&nbsp;</em></p> John Loehr Robert Lynch Johanna Mappes Tuomas Salmi Jenni Pettay Virpi Lummaa ##submission.copyrightStatement## 2017-12-15 2017-12-15 52 59 70 10.23979/fypr.65212 Book review: Grandfathers - Global Perspectives <p>Buchanan, A &amp; Rotkirch, A.
