Impacts of the COVID‐19 Lockdown on Gender Inequalities in Time Spent on Paid and Unpaid Work in Singapore
The COVID‐19 pandemic has affected gender inequalities in time spent on paid and unpaid work globally. Few studies outside of the Western context (i.e., countries in Australasia, Europe, or the Americas) have used longitudinal data to compare time use before and during the pandemic, focused on potential mechanisms through which the pandemic affects gender inequalities in time use, or examined the heterogeneous effects of socioeconomic status. We examine the impact of the COVID‐19 lockdown on gender inequalities in time spent on paid work, housework, and childcare in Singapore. Using a panel dataset of 290 married women interviewed before, during, and after the lockdown, and applying between‐within models, we find that gender gaps in housework hours increased during and persisted after the lockdown, even as the gender gap in paid work hours narrowed. The gap in childcare hours expanded among households with fewer resources but decreased among households with more resources. Mothers responded to loss of income and employment by increasing their childcare and housework time more than fathers, suggesting that “doing gender,” rather than time availability or material resources, provide the key mechanism explaining gendered changes in time use. Our results highlight that when a pandemic strikes, women, especially those in less‐resourced households, were put in a particularly vulnerable position compared to men.

Changes in Working Women’s Self-Reported Subjective Wellbeing and Quality of Interpersonal Relationships During COVID-19: A Quantitative Comparison of Essential and Non-essential Workers in Singapore
The COVID-19 pandemic has affected working women’s well-being in different ways due to contrasting national responses. This article focuses on the specific context of Singapore, which implemented differentiated rules for workers: essential workers continued to report to workplaces, while non-essential workers were required to work from home. This policy had far-reaching implications for working women, who are more likely than husbands to juggle paid work and household duties. The article uses longitudinal data collected in 2018 and during the pandemic in 2020, specifically during Singapore’s lockdown period, to measure changes in 287 working women’s self-reported levels of stress, fatigue, and quality of interpersonal relationships by essential worker status. While all workers were affected by the pandemic, female essential workers were more likely than their non-essential peers to report declines in stress levels from 2018 to 2020, and less likely to report changes in spousal relationships, both positive and negative. Findings suggest that the differences were driven by exposure to quarantine conditions faced by non-essential workers. Our results highlight the importance of policies supporting frontline workers and more gender-equitable labour market policies to support married women juggling the twin demands of employment and household responsibilities.

Changes in Frequency and Patterns of Marital Sexual Activity During COVID-19: Evidence from Longitudinal Data Prior to, During and After Lockdown in Singapore
Background: The literature suggests that the pandemic has affected sexual activity and sexual desire around the world, potentially due to increased levels of stress, movement restrictions under lockdown conditions, and changes in relationship quality.Aim: To investigate changes in frequency and patterns of marital sexual activity and the role of potential factors underlying these changes, during and after COVID-19 lockdown.Methods: This longitudinal study followed 409 heterosexual married female participants who completed a baseline survey in April–July 2018 and biweekly online surveys over the next 14 weeks; an online survey in May 2020 during the lockdown in Singapore; and an online survey in June 2020 after the lockdown was lifted. Participants were recruited in 2018 using street intercept and screened for inclusion and exclusion criteria. Logistic fixed-effects models were used to test for changes in frequency and patterns of marital sexual activity and assess underlying factors. Pseudo-design-based sample weights were applied.Outcomes: The 2018 in-person baseline survey collected information on demographic characteristics and ideal frequency of marital sex, while follow-up online questionnaires in May–June 2020 included items on exact dates of marital sexual activity of previous weeks; stress and fatigue levels; both spouses’ stay-at-home statuses during lockdown; and marital satisfaction.Results: 409 heterosexual married women were included in this study. Compared to pre-pandemic levels, the proportion of participants not having marital sex within a week remained stable while weekly sexual frequency increased, with more evenly distributed sexual activity on weekdays and weekends. Stress, fatigue, and marital satisfaction levels predicted probability of non-activity and sexual frequency.Clinical Translation: The increase in weekly sexual frequency has implications for sexual and reproductive health, including sexual satisfaction and prevalence of infertility and low birth weight associated with waiting time to pregnancy.Strengths & Limitations: The longitudinal nature of the dataset provides unique insights into differences in frequency of marital sexual activity during compared to before the pandemic. Unlike previous studies, detailed data on exact dates of sexual activity allow for detection of differences in sexual activity by day of the week. However, dates of sexual activity were recorded retrospectively and may contain recall errors. Data were collected only from wives and hence dates of marital sexual activities were not cross-validated with husbands.Conclusion: Results point to more active and flexible marital sex lives during the pandemic, with effects that persisted after the lockdown ended.

Ideal and actual intervals to first birth in Singapore
Postponement of first births is a key cause of declining fertility rates, especially in East Asia where recovery from delayed childbearing has been weak. This paper investigates achievement of ideal ages at marriage and first birth in Singapore using survey data on 657 married women aged 25–34. Almost 50 per cent marry within one year of their ideal age, but less than 30 per cent have their first child within six months of their ideal interval to first birth, with around 50 per cent waiting longer than ideal. The high proportion of women experiencing a longer-than-ideal first birth interval was observed across all age and educational groups. Regression results show that co-residence with a foreign domestic worker and paid leave entitlements are associated with higher probability of achieving their ideal first birth interval, whereas availability of parents/in-laws, husband’s help and unpaid leave do not reduce time to childbearing.

Stress, Fatigue, and Sexual Spontaneity Among Married Couples in a High-Stress Society: Evidence from Sex Diary Data from Singapore
This paper investigates the associations between stress and fatigue and sexual spontaneity among heterosexual married couples in Singapore, a high-income society with high work performance expectations and long working hours. Data on self-reported menstrual dates, sexual activity within the marriage, and stress and fatigue levels were collected from 657 married women aged 25–34 years through biweekly online diaries over 14 weeks. Using a two-way fixed effects logistic model which controlled for time-invariant individual fixed effects and menstrual cycle fixed effects, the paper tests three hypotheses: (1) sexual activity is significantly lower on weekdays compared to weekends and public holidays, (2) sexual activity is significantly lower during periods when women reported higher stress and fatigue, and (3) stress and fatigue are more predictive of sexual activity during weekdays than during weekends. Frequencies of marital sexual intercourse during the diary keeping period were 3.69 and 2.55 per 30 days among women aged 25–29 and 30–34 years, respectively, much lower than ideal frequencies of 6.40 and 5.23. Consistent with all three hypotheses, there was a strong positive weekend effect and a weak but positive public holiday effect, and strong negative effects of both stress and fatigue, especially during weekdays. There was no evidence of compensatory sex on weekends to make up for hectic workweeks. Increased support for work-life balance can contribute to more spontaneous marital sex lives and may reduce underachievement of ideals for sexual intimacy and childbearing in Singapore.
