Dissecting the midlife crisis: disentangling social, personality and demographic determinants in social brain anatomy

In any stage of life, humans crave connection with other people. In midlife, transitions in social networks can relate to new leadership roles at work or becoming a caregiver for aging parents. Previous neuroimaging studies have pinpointed the medial prefrontal cortex (mPFC) to undergo structural remodelling during midlife. Social behavior, personality predisposition, and demographic profile all have intimate links to the mPFC according in largely disconnected literatures. Here, we explicitly estimated their unique associations with brain structure using a fully Bayesian framework. We weighed against each other a rich collection of 40 UK Biobank traits with their interindividual variation in social brain morphology in ~10,000 middle-aged participants. Household size and daily routines showed several of the largest effects in explaining variation in social brain regions. We also revealed male-biased effects in the dorsal mPFC and amygdala for job income, and a female-biased effect in the ventral mPFC for health satisfaction.

Dissecting the midlife crisis: Disentangling social, personality and demographic determinants in social brain anatomy

In any stage of life, humans crave social connection with other people. In midlife, transitions in social networks can be related to new leadership roles at work or becoming a caregiver for aging parents. Previous neuroimaging studies have reported that during midlife, especially the medial prefrontal cortex (mPFC) undergoes structural remodeling changes. Social behavior, personality predisposition, and demographic profile all bear intimate relation with the mPFC according to separate literature streams. To integrate these three areas commonly studied in isolation, we explicitly modeled their unique links with brain structure using a fully probabilistic framework. We weighed against each other a rich collection of 40 traits with their interindividual variation in social brain morphology in ~10,000 middle-aged UK Biobank participants (40-69 years at recruitment). Across conducted analyses, household size and daily routine schedules showed several of the largest effects in explaining variation in social brain regions. We revealed male-biased effects in the dorsal mPFC and amygdala for job income, and a female-biased effect in the ventral mPFC for health satisfaction. Our population investigation offers a more complete perspective into how adults at the midlife milestone may navigate life depending on their identity and status.

Undoing age, redefining gender, and negotiating time: Embodied experiences of midlife women in endurance sports

Despite the increasing participation of midlife women in sports, and biomedical and consumerist discourses encouraging physical activity, research on intersections of age, gender, and the body in sports is lacking or fragmentary. Based on in-depth interviews with Israeli women aged 40–60 years participating in marathons, ultramarathons, and triathlons, we explore how they experience their participation and how these experiences correspond with normative socio-temporal assumptions about midlife transitions, gender, and the body. Findings reveal that endurance sports enable midlife women to challenge dominant discourses on the “decaying” and “menopausal” body by undoing age and formulating gender narratives that include new identities and negotiations of temporal orders. The interplay between undoing age and redefining gender operates through two mechanisms: “embodied experiences” that introduce the body as a material reality and a source of critical knowledge, and the liminality of mid-age as a life-course transition characterized by the absence of institutional and symbolic anchors. We make a twofold contribution to the critical literature on gender and life course. First, we develop the concept of embodied experiences as a vantage point for understanding the intersections of age and gender. Second, we highlight the potential of participation in endurance sports for negotiating temporal orders and formulate new narratives of femininity and aging.

Midlife Transitions—The Integrative Preventive Medicine Approach to the Evaluation and Management of Menopause and Andropause

Much more has been written about the pros and cons of hormone therapy for women in menopause than has been studied for men in andropause. In two separate sections, this chapter explores those pros and cons in more detail, as well as how to customize recommendations for individuals. Alternative modalities for managing symptoms are discussed, along with the key lifestyle interventions such as resistance training that can counter some of the physical changes associated with declining hormone levels. Attending to the emotional changes that may accompany menopause and andropause is an important component of working with women and men in this time of their lives. A whole-person approach, incorporating preventive and lifestyle medicine practices, may help shift concerns about aging and hormonal changes into a window of opportunity to embrace this next stage of life in as healthy and vibrant a way as possible.

Stressful Work Trajectories and Depressive Symptoms in Middle-Aged Couples: Moderating Effect of Marital Warmth

Objectives: The present study investigated the decade-long actor and partner infleunces between husbands’ and wives’ trajectories of stressful work conditions (SWCs) and their depressive symptoms while also considering the moderation of these influences by spousal warmth. Methods: Participants were 330 middle-aged dual-earner couples from the Iowa Midlife Transitions Project. Husbands and wives reported on own SWCs and reported on parenter’s warmth in the years of 1991, 1992, and 1994. Depressive symptoms for husbands and wives were measured by the SCL-90-R in 1994 and 2001. Structural equation models, growth curves, and longitudinal data were used to perform our analyses. Results: For husbands and wives, trajectories of SWCs over early middle years (1991-1994) contributed to depressive symptoms in 1994. Notably, for husbands and wives, the severity (level) of SWCs in 1991 had a persistent influence on depressive symptoms a decade later (2001). For husbands, under conditions of wives’ low warmth, SWCs exerted a relatively strong influence on their depressive symptoms. However, under conditions of high warmth from wives, most of these influences were greatly diminished. Discussion: Results from the current study indicate that contextual life experiences can have a persistent health influences over the life course.

Transitions, Wellness, and Life Satisfaction: Implications for Counseling Midlife Women

A diverse sample of 224 women, aged 35 to 65, participated in a study to examine the relations among transitions, life satisfaction, and wellness. The Women's Midlife Transitions Survey, developed for this study, provided information on the timeliness, expectedness, and impact of common midlife transitions. Implications for mental health counselors include the need to help midlife women understand and cope with a variety of common life changes that individually and collectively help to define their midlife experience.
