We have previously presented a multidimensional Aging Society Index, a weighted summation of five domains central to successful adaptation to societal aging: well-being, productivity and engagement, equity, cohesion and security, as a tool to assess countries’ adaptation to demographic transformation. As the index was based on data from developed countries and some of the individual metrics or weightings may not be well suited for application to low- and middle-income countries, we here present the scores on a modified index (Global Aging Society Index) on 143 countries distributed across the span of economic development. Only 5 out of 143 (3.5%) countries had higher scores for women than men. Countries with the most notable gender differences were primarily low-income countries. The multidimensional index permits cross-national comparisons and may facilitate the identification of targets for developing policies and programs to enhance the likelihood that older persons will age successfully. The authors score and rank the adaptation to societal aging across 143 countries using a newly developed index called the Global Aging Society Index, which may be helpful to identify targets for the development of policies and programs to enhance the likelihood that older people will age successfully.

To understand how the health of older adults today compares to that of previous generations, we estimated intrinsic capacity and subdomains of cognitive, locomotor, sensory, psychological and vitality capacities in participants of the English Longitudinal Study of Ageing and the China Health and Retirement Longitudinal Study. Applying multilevel growth curve models, we found that more recent cohorts entered older ages with higher levels of capacity, while subsequent age-related declines were somewhat compressed compared to earlier cohorts. Trends were most evident for the cognitive, locomotor and vitality capacities. Improvements were large, with the greatest gains being in the most recent cohorts. For example, a 68-year-old participant of the English Longitudinal Study of Ageing born in 1950 had higher capacity than a 62-year-old born 10 years earlier. Trends were similar for men and women and were generally consistent across English and Chinese cohorts. Possible causes include broad societal influences and improvements in medical care. Intrinsic capacity includes a person’s mental and physical capacities. The authors examined cohort trends in intrinsic capacity in two large English and Chinese studies. They report that more recently born participants entered older ages with markedly higher levels of functioning, while subsequent age-related declines were somewhat delayed.

A satisfying sex life is a key component of health and well-being for many older women. However, there is insufficient awareness of and care for women’s sexual health. This Comment discusses steps healthcare providers can take to support women’s sexual health across the lifespan, which should be a top priority.

People today are choosing to have children later in life, often in their thirties and forties, when their fertility is in decline. We sought to identify and compile effective methods for improving either male or female fertility in this context of advanced reproductive age. We found few clinical studies with strong evidence for therapeutics that mitigate reproductive aging or extend fertility; however, this Perspective summarizes the range of emerging experimental strategies under development. Preclinical studies, in mouse models of aging, have identified pharmaceutical candidates that improve egg and sperm quality. Further, a diverse array of medically assisted reproduction methodologies, including those that stimulate rare ovarian follicles and rejuvenate egg quality using mitochondria, may have future utility for older patients. Finally, we highlight the many knowledge gaps and possible future directions in the field of therapeutics to extend the age of healthy human reproduction. People now choose to start families in their 30s to 40s, when fertility is low owing to reproductive aging. In this Perspective, the authors highlight the absence of clinically confirmed therapeutics to mitigate reproductive aging or extend fertility, and they summarize the range of emerging strategies and point to knowledge gaps and future directions in the field.

Reproductive health is fundamentally connected with overall health. The Bia-Echo Asia Centre for Reproductive Longevity and Equality discusses an innovative approach to healthy longevity that is tailored uniquely to individual patterns of aging, which will require reproductive medicine, biological aging research and public engagement to join forces.

As fertility rates decline and childbearing age increases globally, assisted reproductive technology (ART) has a crucial role in enhancing birth rates and will contribute substantially to future generations. ART has fulfilled family formation wishes for many individuals facing infertility and aids in solving demographic challenges. Today, up to 9% of the European population is conceived after ART. Considerable advancements in ARTs have improved the effectiveness of treatment, but the ultimate quality control in ART is healthy offspring. Therefore, it is of utmost importance to monitor the health of individuals conceived through ART, and ensure that ART not only provides for the birth of healthy children but also for health into old age.

Substantial shifts in reproductive behaviors have recently taken place in many high-income countries including earlier age at menarche, advanced age at childbearing, rising childlessness and a lower number of children. As reproduction shifts to later ages, genetic factors may become increasingly important. Although monogenic genetic effects are known, the genetics underlying human reproductive traits are complex, with both causal effects and statistical bias often confounded by socioeconomic factors. Here, we review genome-wide association studies (GWASs) of 44 reproductive traits of both female and male individuals from 2007 to early 2024, examining reproductive behavior, reproductive lifespan and aging, infertility and hormonal concentration. Using the GWAS Catalog as a basis, from 159 relevant studies, we isolate 37 genes that harbor association signals for four or more reproductive traits, more than half of which are linked to rare Mendelian disorders, including ten genes linked to reproductive-related disorders: FSHB, MCM8, DNAH2, WNT4, ESR1, IGSF1, THRB, BRWD1, CYP19A1 and PTPRF. We also review the relationship of reproductive genetics to related health and behavioral traits, aging and longevity and the effect of parental age on offspring outcomes as well as reflecting on limitations, open questions and challenges in this fast-moving field. Benonisdottir et al. review the genetics of reproductive traits and examine how these associate with links to health, behavior, aging and longevity as well as outcomes for offspring.

Caloric restriction (CR) slows biological aging and prolongs healthy lifespan in model organisms. Findings from the CALERIE randomized, controlled trial of long-term CR in healthy, nonobese humans broadly supports a similar pattern of effects in humans. To expand our understanding of the molecular pathways and biological processes underpinning CR effects in humans, we generated a series of genomic datasets from stored biospecimens collected from n = 218 participants during the trial. These data constitute a genomic data resource for a randomized controlled trial of an intervention targeting the biology of aging. Datasets include whole-genome single-nucleotide polymorphism genotypes, and three-timepoint-longitudinal DNA methylation, mRNA and small RNA datasets generated from blood, skeletal muscle and adipose tissue samples (total sample n = 2,327). The CALERIE Genomic Data Resource described in this article is available from the Aging Research Biobank. This multi-tissue, multi-omics, longitudinal data resource has great potential to advance translational geroscience. ClinicalTrials.gov registration: NCT00427193 . Ryan and colleagues present multi-tissue, multi-omics, longitudinal datasets from the CALERIE phase 2 randomized controlled trial of caloric restriction in humans, providing a powerful resource for translational geroscience.

Sex hormone signaling declines during aging, from early midlife through menopause, as a consequence of reduced circulating estrogens and decreased receptiveness to these hormones in target tissues. Estrogens preserve energy homeostasis and promote metabolic health via coordinated and simultaneous effects throughout the brain and body. Age-associated loss of estrogen production during menopause has been implicated in a higher risk for metabolic diseases and increased mortality. However, it remains unclear whether age-associated changes in homeostasis are dependent on reduced estrogen signaling during menopause. Although menopausal hormone therapies containing estrogens can alleviate symptoms, concerns about the risks involved have contributed to a broad decline in the use of these approaches. Non-hormonal therapies have emerged that target tissues or pathways with varying levels of selectivity, reducing risk. We summarize here the broad effects of estrogen loss on homeostasis during menopause, current and emerging therapies and opportunities for understanding homeostatic disruptions associated with menopause. Sex hormone signaling declines during aging. In this Review, the authors provide an overview of the role of estrogen signaling in the maintenance of energy homeostasis and the dysregulation of this equilibrium during menopause, dissect the contributions of hormonal decline and aging to health changes and discuss current and emerging therapies.
