“The Impact of Demographic Change on Transfers of Care and Associated Well-being”

This study aims to evaluate the impact of demographic change on long-term, macro-level childcare and adult care transfers, accounting for the associated well-being effects of informal caregiving. We measure the impact of demographic change on non-monetary care exchanged between different groups by estimating matrices of time transfers by age and sex, and weighting the time flows by self-reported indicators of well-being, for activities related to childcare and adult care. The analysis employs cross-sectional data from the American Time Use Survey 2011–2013, and the Panel Study of Income Dynamics, Disability, and Use of Time Module 2013 to produce the estimates of well-being associated with the two forms of care and their future projections. Both men and women experience more positive feelings when caring for children than when caring for adults. As a whole, caregiving is an overwhelmingly more positive experience than it is negative across both genders and care types. Yet women often report more tiredness and stress than men when providing childcare, while also experiencing more pain while performing adult care, as compared to childcare activities. Women of reproductive ages spend double the amount of care time associated with negative feelings, relative to men, most of which is spent on early childcare. We project a progressively widening gender gap in terms of positive feelings related to care in the coming decades. Future reductions in absolute caregiver well-being influenced by demographic changes at the population level may reduce workforce participation, productivity, and adversely impact psycho-physical condition of caregivers, if not offset by targeted policies.

Replication and reproducibility issues in the relationship between C-reactive protein and depression: A systematic review and focused meta-analysis

One of the most common inflammatory markers examined in depression is C-reactive protein (CRP). However, the magnitude of the association between CRP and depression when controlling for potentially confounding factors such as age, sex, socio-economic status, body mass index, medication and other substance use, and medical illness, is unclear. Inconsistencies in other methodological practices, such as sample collection, assaying, and data cleaning and transformation, may contribute to variations in results. We aggregate studies that examined the association between CRP and depression in two ways. First, a systematic review summarizes how studies of CRP and depression have reported on methodological issues. Second, a tiered meta-analysis aggregates studies that have adhered to various levels of methodological rigor. Findings from the systematic review indicate a lack of protocol detail provided. The effect between depression and CRP was small, but highly significant across all stages of the meta-analysis (p < 0.01). The effect size in the most methodologically rigorous stage of the meta-analysis, which included studies controlling for age, sex, obesity, medical conditions and substance, medication, or psychosocial factors, was small (r = 0.05). There were also only 26 articles in this stage (13% of studies from the systematic review), suggesting that more studies that consistently account for these confounding factors are needed. Additionally, an a priori quality score of methodological rigor was a significant moderator in this stage of the meta-analysis. The effect size was strikingly attenuated (r = 0.005) and non-significant in studies with higher quality scores. We describe a set of recommended guidelines for future research to consider, including sample collection and assaying procedures, data cleaning and statistical methods, and control variables to assess.
