“…In Western European countries, around 20% of women born around 1965 remained childless, with the highest levels of permanent childlessness now in East Asia, ranging from 28% (Japan) to 35% (Hong Kong) for women born in 1975 7,8 . There has also been a sharp increase in childlessness over the last decades in countries such as in Finland, increasing since the 1970s from 14% to 22% (women aged 40 years) and 22% to 32% (men) 9,10 .…”

Background. Approximately 20% of men and 15% of women remain childless at the end of their reproductive lifespan, with childlessness increasing over time, yet we lack a comprehensive understanding of the role and relative importance of diseases associated with childlessness, particularly among men. Methods. We examined all individuals born in Finland (n=1,035,928) and Sweden (n=1,509,092) between 1956 and 1968 (men) or 1956 and 1973 (women) and followed them up until the end of 2018. Socio-demographic, health, and reproductive information was obtained from nationwide registers. We assessed the association of 414 diseases across 16 categories with having no children by age 45 (women) and 50 (men) using a matched pair case-control design based on 71,524 pairs of full-sisters and 77,622 full-brothers who were discordant for childlessness as well as a population-based approach. Findings. Mental-behavioral, congenital anomalies, and endocrine-nutritional-metabolic disorders had the strongest associations with childlessness. Novel associations were discovered with inflammatory (eg. myocarditis) and autoimmune diseases (eg. juvenile idiopathic arthritis). Mental-behavioral disorders had stronger associations amongst men, particularly for schizophrenia and acute alcohol intoxication, while congenital anomalies, obesity-related diseases such as diabetes, and inflammatory diseases had stronger associations amongst women. Associations were dependent on the age at onset of the disease, with the strongest association observed earlier in women (21-25 years old) than men (26-30 years old). For most diseases, the association with childlessness was mediated by singlehood, especially in men. Some diseases, however, remained associated with childlessness among partnered individuals, including some mood- and endocrine-nutritional-metabolic disorders. All results can be explored in an interactive online dashboard. Interpretation. We provide evidence that disease burden across multiple domains is associated with childlessness, identifying modifiable mental-behavioral disorders and novel autoimmune and inflammatory diseases. Evidence can be used for targeted health interventions to counter decreasing fertility, reproductive health, involuntary childlessness, and shrinking populations.

“…According to the literature, total fertility has also fallen from an already low level of 1.6 children per woman in the 1990s to 1.43 in 2016(Human Fertility Database, 2022. Childlessness has more than doubled, rising from 12% of Japanese women born in 1955 to 27% of those born in 1975 (Sobotka, 2021). In comparison, lifelong childlessness among Swedish women has remained stable at approximately 14% across the cohorts born during the period 1955-1974(Jalovaara et al, 2018.…”

The increase in one-person households (OPHs) in the developed world is often seen as the result of a trend in which individualistic values and behaviors are replacing family solidarity. Nordic countries have been identified as frontrunners in this development. In Asia, equally developed countries like Japan retain elements of a strong-family system and an asymmetrical gender regime, simultaneously as they are experiencing rapid increases in OPHs. This article aims to uncover how the demographic and socioeconomic composition of OPHs have developed since the 1990s among working-age women in Sweden and Japan. Our results show that, in particular, civil status and income play different roles for OPH-living in Sweden and Japan. In contrast to Japan, the level of OPHs remained stable over time in Sweden, and even declined among women with high incomes. This suggests that the negative association between family formation and women’s economic activity is temporary and only prevails as long as society has not adapted to the convergence of men’s and women’s socioeconomic roles. The findings are discussed in light of the “second demographic transition” and “dual equilibrium theory”.

“…Further, the introduction of Western-style dietary patterns to East Asian regions (such as Hong Kong and South Korea) is thought to be a key driver of obesity and cardiovascular disease in the region [ 115 ]. In tandem, the total fertility rate throughout East Asia has been falling precipitously over the last 50 years, and is now below the replacement rate of 2.1 [ 116 , 117 ]. Poor nutrition, obesity, and chronic disease could have contributed to infertility throughout the region, alongside the possible other influencing factors (cost of living, social programs, as well as others).…”

Anti-Inflammatory Diets in Fertility: An Evidence Review

Infertility is a global health concern affecting 48 million couples and 186 million individuals worldwide. Infertility creates a significant economic and social burden for couples who wish to conceive and has been associated with suboptimal lifestyle factors, including poor diet and physical inactivity. Modifying preconception nutrition to better adhere with Food-Based Dietary Guidelines (FBDGs) is a non-invasive and potentially effective means for improving fertility outcomes. While several dietary patterns have been associated with fertility outcomes, the mechanistic links between diet and infertility remain unclear. A key mechanism outlined in the literature relates to the adverse effects of inflammation on fertility, potentially contributing to irregular menstrual cyclicity, implantation failure, and other negative reproductive sequelae. Therefore, dietary interventions which act to reduce inflammation may improve fertility outcomes. This review consistently shows that adherence to anti-inflammatory diets such as the Mediterranean diet (specifically, increased intake of monounsaturated and n-3 polyunsaturated fatty acids, flavonoids, and reduced intake of red and processed meat) improves fertility, assisted reproductive technology (ART) success, and sperm quality in men. Therefore, integration of anti-inflammatory dietary patterns as low-risk adjunctive fertility treatments may improve fertility partially or fully and reduce the need for prolonged or intensive pharmacological or surgical interventions.
