Concentration of critical events over the life course and life satisfaction later in life.

Critical events create turning points, disrupt individuals' life courses, and affect wellbeing. Periods of life densely populated with critical events may translate into an acute resource drain, affecting long-term wellbeing more strongly than if the same events were sparsely distributed. We investigate how the co-occurrence of critical events and their concentration in time influence life satisfaction in later life. To do so, we construct a novel indicator, the Concentration Index, based not only on the number but also on the time lag between occurrences. Using retrospective information on critical events in family, work, health, and residential trajectories in Switzerland, we show that the higher the concentration in time of critical events is, the stronger their negative long-term relation to wellbeing, net of sociodemographic characteristics, the total number of events ever experienced, and the time since the last event. Furthermore, relevant gender and social origin differences emerged with a stronger negative association with wellbeing among men and respondents from low socioeconomic backgrounds. Our work clearly shows that simply counting the number of events gives only a partial and potentially inaccurate measure of the complexity of the life course and its relationship with quality of life. Not only how many events experienced matter but also the spacing between them.

The Swiss neighbourhood index of socioeconomic position: update and re-validation.

BACKGROUND: The widely used Swiss neighbourhood index of socioeconomic position (Swiss-SEP 1) was based on data from the 2000 national census on rent, household head education and occupation, and crowding. It may now be out of date. METHODS: We created a new index (Swiss-SEP 2) based on the 2012-2015 yearly micro censuses that have replaced the decennial house-to-house census in Switzerland since 2010. We used principal component analysis on neighbourhood-aggregated variables and standardised the index. We also created a hybrid version (Swiss-SEP 3), with updated values for neighbourhoods centred on buildings constructed after the year 2000 and original values for the remaining neighbourhoods. RESULTS: A total of 1.54 million neighbourhoods were included. With all three indices, the mean yearly equivalised household income increased from around 52,000 to 90,000 CHF from the lowest to the highest index decile. Analyses of mortality were based on 33.6 million person-years of follow-up. The age- and sex-adjusted hazard ratios of all-cause mortality comparing areas in the lowest Swiss-SEP decile with areas of the highest decile were 1.39 (95% confidence interval [CI] 1.36-1.41), 1.31 (1.29-1.33) and 1.34 (1.32-1.37) using the old, new and hybrid indices, respectively. DISCUSSION: The Swiss-SEP indices capture area-based SEP at a high resolution and allow the study of SEP when individual-level SEP data are missing or area-level effects are of interest. The hybrid version (Swiss-SEP 3) maintains high spatial resolution while adding information on new neighbourhoods. The index will continue to be useful for Switzerland's epidemiological and public health research.

A dynamic perspective on the evolution of perceived stress levels in Switzerland: drivers before and during the COVID-19 pandemic.

As a major socio-historical event affecting different aspects of life, the COVID-19 pandemic presents a unique opportunity to study how different population groups adapt. We investigate the impact of this crisis on the evolution of perceived stress in the short and medium term in Switzerland, using data of the Swiss Household Panel from 2016 to early 2021, which include annual measures of perceived stress and a study between waves, conducted in May and June 2020 at the end of the first semi-lockdown. Using the longitudinal structure of the data with pre-crisis measurements, we estimate pooled OLS, fixed effects and first difference models, which include socio-demographic variables, life events, socio-economic status, work-related variables, stress-reducing resources and restrictions in place. Results for the overall population show a continuous increase in stress levels between 2016 and 2019 and a stress reduction right after the first semi-lockdown followed by a return to pre-pandemic levels. Privileged groups with higher levels of stress before the pandemic were most likely to reduce perceived stress. Characteristics related to more favourable trajectories include stable or improved financial situations and high levels of education (short-term effects), and high-pressure jobs and working hours (short- and medium-term effects). Our analyses reveal the importance of resources, such as social relations and work-life balance, to individuals' management of the effects of the pandemic. Our results show that the effects of the pandemic on perceived stress are context-specific. They underline the importance of longitudinal analyses to understand the complexity of vulnerability and adaptation processes.

The gendered consequences of the COVID-19 lockdown on unpaid work in Swiss dual earner couples with children.

This article assesses the gendered impact of COVID-19 measures on changes in time that Swiss dual earner couples spent on unpaid work during the pandemic, focusing on families with children. Overcoming some of the methodological shortcomings of previous studies, high-quality representative panel data allow us to examine the change in time invested in housework and childcare before and during the pandemic, and test theoretical assumptions as to the mechanisms underlying the observed patterns. Gender inequalities are explained by the couple's work division prior to, and at the onset of, the pandemic and interpreted in the light of key theoretical approaches (economics of the family, bargaining and time availability, doing gender). Our results imply that in particular changes in the time availability of the partner are relevant for changes in time spent on housework, while in case of care work, the own time availability matters more. Moreover, we also found that the respondents' economic bargaining power within the couple matters both for housework and care work. Finally, the implemented COVID-19 measures neither led to an increase in patriarchal power structures nor did they foster an increase in equality for unpaid work among women and men. Instead, the results show that changes in time availability due to short-time, remote or overtime working schemes determined changes in time spent on unpaid care to a larger extent than gender alone.

Parenthood and Well-Being: The Moderating Role of Leisure and Paid Work.

This study contributes to our knowledge on the association between parenthood and psychological well-being by examining whether pre-parenthood lifestyles (leisure and paid work) moderate the transition to parenthood. We expected that people with less active lifestyles would find it easier to adapt to the demands of parenthood. Using eleven waves of the Swiss Household Panel (N = 1332 men and 1272 women; 1999-2008, 2010), fixed effects models are estimated for men and women separately. Results show that-on average-parenthood was not associated with well-being for men, whereas it increased well-being for women. As expected, the well-being premium/cost to parenthood was contingent upon individuals' lifestyle before the transition to parenthood. For men, parenthood reduced well-being, but only if they frequently participated in leisure before the birth of the child. For women, motherhood had a beneficial effect on well-being but this effect was weaker for women who combined leisure with working long hours before motherhood.

Just like family: fictive kin relationships in the Netherlands.

OBJECTIVES: This study examined the extent to which older adults in the Netherlands include a nonrelative as part of their family (create fictive kin), and whether this process is similar in other age groups. It assessed the importance of absence of close family ties and the experience of divorce in the family network for the creation of fictive kin. METHOD: Using data from the Netherlands Kinship Panel Study, logistic regression models for the different age groups tested the importance of absence of primary family relationships and the experience of divorce in the family among three age groups (18-40, 41-60, 61-79, N = 6,571). RESULTS: Prevalence of fictive kin relationships was higher in older age groups. Both the absence of close family relationships and the experience of divorce within the family were related to having fictive kin, although the latter was only found in the youngest age group. For older adults never having married, being widowed or divorced were important predictors of having fictive kin relationships. DISCUSSION: The study provides support for the idea that the creation of fictive kin is a form of substitution for absent family members and shows that older adults in the Netherlands are active agents in the construction of their family network.

A Swiss neighbourhood index of socioeconomic position: development and association with mortality.

BACKGROUND: Area-based measures of socioeconomic position (SEP) suitable for epidemiological research are lacking in Switzerland. The authors developed the Swiss neighbourhood index of SEP (Swiss-SEP). METHODS: Neighbourhoods of 50 households with overlapping boundaries were defined using Census 2000 and road network data. Median rent per square metre, proportion households headed by a person with primary education or less, proportion headed by a person in manual or unskilled occupation and the mean number of persons per room were analysed in principle component analysis. The authors compared the index with independent income data and examined associations with mortality from 2001 to 2008. RESULTS: 1.27 million overlapping neighbourhoods were defined. Education, occupation and housing variables had loadings of 0.578, 0.570 and 0.362, respectively, and median rent had a loading of -0.459. Mean yearly equivalised income of households increased from SFr42 000 to SFr72 000 between deciles of neighbourhoods with lowest and highest SEP. Comparing deciles of neighbourhoods with lowest to highest SEP, the age- and sex-adjusted HR was 1.38 (95% CI 1.36 to 1.41) for all-cause mortality, 1.83 (95% CI 1.71 to 1.95) for lung cancer, 1.48 (95% CI 1.44 to 1.51) for cardiovascular diseases, 2.42 (95% CI 1.94 to 3.01) for traffic accidents, 0.93 (95% CI 0.85 to 1.02) for breast cancer and 0.86 (95% CI 0.78 to 0.95) for suicide. CONCLUSIONS: Developed using a novel approach to define neighbourhoods, the Swiss-SEP index was strongly associated with household income and some causes of death. It will be useful for clinical- and population-based studies, where individual-level socioeconomic data are often missing, and to investigate the effects on health of the socioeconomic characteristics of a place.
