Locking Down Gender Roles? A Time-Use Perspective on Gender Division of Household Labour during the COVID-19 Pandemic Lockdown in Belgium.

The impact of the COVID-19 pandemic on the division of household labour could continue to lock down or start to break gender roles. Using time-use data of n = 473 individuals collected during the lockdown restrictions in Belgium from March to May 2020, we analyse the gendered division of routine and non-routine household labour in absolute time use and relative shares. We compare against the Belgian time-use data of 2013 for the same time period (n = 678 individuals). A time-demanding work and living situation associate with an increase in men's time spent on household labour during the lockdown but not with a change in women's time use. The gender gap closes in absolute time but not in relative shares of routine and non-routine household labour. The limited impact of the COVID-19 pandemic on the gender division of household labour indicates a temporal rather than a substantial change in gender roles.

Exploring human mixing patterns based on time use and social contact data and their implications for infectious disease transmission models.

BACKGROUND: The increasing availability of data on social contact patterns and time use provides invaluable information for studying transmission dynamics of infectious diseases. Social contact data provide information on the interaction of people in a population whereas the value of time use data lies in the quantification of exposure patterns. Both have been used as proxies for transmission risks within in a population and the combination of both sources has led to investigate which contacts are more suitable to describe these transmission risks. METHODS: We used social contact and time use data from 1707 participants from a survey conducted in Flanders, Belgium in 2010-2011. We calculated weighted exposure time and social contact matrices to analyze age- and gender-specific mixing patterns and to quantify behavioral changes by distance from home. We compared the value of both separate and combined data sources for explaining seroprevalence and incidence data on parvovirus-B19, Varicella-Zoster virus (VZV) and influenza like illnesses (ILI), respectively. RESULTS: Assortative mixing and inter-generational interaction is more pronounced in the exposure matrix due to the high proportion of time spent at home. This pattern is less pronounced in the social contact matrix, which is more impacted by the reported contacts at school and work. The average number of contacts declined with distance. On the individual-level, we observed an increase in the number of contacts and the transmission potential by distance when travelling. We found that both social contact data and time use data provide a good match with the seroprevalence and incidence data at hand. When comparing the use of different combinations of both data sources, we found that the social contact matrix based on close contacts of at least 4 h appeared to be the best proxy for parvovirus-B19 transmission. Social contacts and exposure time were both on their own able to explain VZV seroprevalence data though combining both scored best. Compared with the contact approach, the time use approach provided the better fit to the ILI incidence data. CONCLUSIONS: Our work emphasises the common and complementary value of time use and social contact data for analysing mixing behavior and analysing infectious disease transmission. We derived spatial, temporal, age-, gender- and distance-specific mixing patterns, which are informative for future modelling studies.

Graduate students locked down? PhD students' satisfaction with supervision during the first and second COVID-19 lockdown in Belgium.

BACKGROUND: Supervisor support is crucial for the successful and timely completion of the PhD and the largest contributor to PhD students' overall job satisfaction. The COVID-19 pandemic affected PhD students' life substantially through delayed experiments, missed timelines, running out of funding, change to online team- and supervisor meetings, mandatory working from home, and social confinement. AIM: This contribution considers PhD students' satisfaction scores to reflect the extent to which PhD students felt supported by their supervisor during the COVID-19 pandemic so far and aims to investigate to what extent did PhD students' satisfaction with supervisor support changed over time. METHOD: It uses two longitudinal two cohorts of wave 4 to 5 of the PhD Survey at a Belgian university. These cohorts are representative of two different ways the COVID-19 pandemic might have impacted doctoral research. Cohort 1 (n = 345) includes a pre-COVID measurement (April-May 2019) and a measurement immediately after the start of the abrupt lockdown in April-May 2020. Cohort 2 (n = 349) includes the measurement at the onset of the pandemic in 2020 and after a year with continuously changing containment policies (April-May 2021). The composite measure of satisfaction with supervisor support is based on six items with high internal consistency. RESULTS: No significant net effect of time was revealed. Instead within subject interactions with time showed that in cohort 1, PhD students at the start of their PhD trajectory and PhD students with family responsibilities reported lower supervisor satisfaction scores over time. In cohort 2, PhD students not pursuing academic careers reported lower satisfaction scores over time. CONCLUSION: In times of crises, special attention needs to be paid to PhD students who are extra susceptible to uncertainties because of their junior status or personal situation, and especially those PhD students for whom doctoral research is not a trajectory to position themselves in academia.

Testing compliance to WHO guidelines for physical activity in Flanders insights from time-use diaries.

BACKGROUND: Regular physical activity decreases the risk for numerous non-communicable diseases. The World Health Organization has suggested physical activity (PA) guidelines that, based on previous research, would provide health benefits to those who comply. The first guideline for health benefits suggests 150 min of moderate PA or equivalent per week. The guideline for additional health benefits suggests 300 min of PA or equivalent per week. The objective of this paper is to analyze to what extent these two WHO PA guidelines for adults are met in the Belgian region of Flanders. Furthermore, we are interested to see which groups are more or less likely to meet the PA guidelines. METHODS: Crosstables and logistic regressions are used on a sample of 3028 adults in the Belgian region of Flanders. All respondents filled in a 7-day time-diary in which they continuously recorded all their activities. RESULTS: Firstly, men are more likely than women to comply to both PA guidelines. Secondly, living with a partner increases the odds to comply to the guidelines. For men, this is the case for both guidelines, while for women, this only applies to the first guideline. Thirdly, women with a young child have lower odds to comply to the guidelines, while having a young child doesn't have an effect for men. CONCLUSION: Previous research on meeting PA guidelines in Flanders shows diverging results. Time-diary data allows researchers to strictly follow the WHO definition when operationalizing compliance to PA guidelines. There is a need for future research that combines time-diaries with a PA questionnaire and accelerometer data to gain more insights on the benefits and pitfalls of both methodologies.

Active work, passive leisure? Associations between occupational and non-occupational physical activity on weekdays.

Research from recent years reports that physical inactivity is a major risk factor for global mortality. Several societal trends in the last decades are likely to have contributed to the increasing prevalence of sedentary lifestyles. Physical activity throughout the day has become much less self-evident and much more a matter of personal effort. Its presumed discretionary character made leisure the time par excellence to compensate for daily inactivity in non-discretionary time. The historical dichotomy of leisure and paid work led to a large body of research assessing the association between occupational and non-occupational physical activity, almost always equated with leisure time physical activity. This study investigates the relationship between occupational and non-occupational physical activity and adds to existing knowledge by breaking down non-occupational physical activity to physical activity in different non-occupational domains of life. Using Belgian time-use data from 2013 coupled with metabolic equivalent of task scores, reveals no direct association between occupational physical activity and physical activity in the domains of leisure, household work and family care, and transport on weekdays after controlling for sociodemographic characteristics. The association between women's occupational physical activity and physical activity in household work and family care is the sole exception. The results suggest that a holistic, naturalistic approach to physical activity taking into account that individuals have to synchronize needs other than paid work (e.g. reproductive and social productive needs) with the institutional and cultural temporal structures of the society they live in, is more appropriate.

Convenience on the menu? A typological conceptualization of family food expenditures and food-related time patterns.

One of the most fundamental, but also controversial, food trends of the past years is convenience food. This article investigates the underexplored relationship between the heterogeneity in (convenience) food consumption (a feature of a food culture's cuisine) and meal patterns (characteristics of a food culture's structure). This study hopes to illustrate that convenience food can be interpreted both as a means to maintain a food culture's structure and as a means to overturn it. Latent Class Cluster Analysis is performed using data from the HBS 2005 survey on families' food expenditures to conceptualize convenience-orientation and to examine the relationships with families' meal behaviors. Whereas outsourcing cooking is most prevalent among single-person households; two-or more-person households are most likely to buy unprocessed and natural foods and to spend most time cooking and eating in. A higher consumption of convenience food is also more likely to affect individuals' kitchen than table habits.

Calculating the Social Rhythm Metric (SRM) and Examining Its Use in Interpersonal Social Rhythm Therapy (IPSRT) in a Healthy Population Study.

In psychiatry, the social zeitgeber theory argues that social life provides important social cues that entrain circadian rhythms. Disturbance of these social cues might lead do dis-entrainment of circadian rhythms and evoke somatic symptoms that increase the risk of mood disorders. In preventing and treating patients with bipolar disorders, the Interpersonal and Social Rhythm Therapy (IPSRT) relies on the Social Rhythm Metric (SRM) to (re)establish patients' social cues and an re-entrain circadian rhythms. Since the SRM quantifies social rhythms that are derived from a patient's interaction with a social environment, this contribution (a) calculates the SRM of the social environment of a representative healthy population study (n = 1249), (b) evaluates the robustness of the SRM as a quantifier of social rhythms by matching the scores of the pilot study, revealing the near absence of variance across population characteristics and investigation months-circadian rhythms need to be entrained for every month and for everyone-and (c) examines its use in IPSRT by relating high SRM-scores to lower psychological distress (p = 0.004) and low SRM-scores to higher social and emotional dysfunction (p = 0.018).

More than preparing a meal? Concerning the meanings of home cooking.

Cooking is one of the basic activities in our lives. However, people frequently feel they fall short of time to cook when facing problems with the temporal organization of daily life. How people think about home cooking is considered to be important for the time they spend on preparing meals. It is assumed that the meaning of cooking differs for different people, depending on the temporal and social context. This contribution allows us to clarify how the meaning of cooking varies according to individual and household characteristics and the cooking occasion. By using the pooled time-diary data from the Flemish time-use surveys from 1999 and 2004 we can examine people's views on cooking in order to understand how people use time for food preparation. Although the results suggest that people consider cooking primarily as a household chore, preparing food can also be a way to please others, as well as themselves. It seems that feelings of time pressure and the family situation are clearly related to men's and women's cooking experiences. Furthermore, the meaning of cooking also tends to be clearly influenced by the meal situation and (the moment of) the day.
