Context: Despite the massive scale of COVID-19 case investigation and contact tracing (CI/CT) programs operating worldwide, the evidence supporting the intervention's public health impact is limited. Objective: To evaluate the Public Health-Seattle & King County (PHSKC) CI/CT program, including its reach, timeliness, effect on isolation and quarantine (I&Q) adherence, and potential to mitigate pandemic-related hardships. Design: This program evaluation used descriptive statistics to analyze surveillance records, case and contact interviews, referral records, and survey data provided by a sample of cases who had recently ended isolation. Setting: The PHSKC is one of the largest governmental local health departments in the United States. It serves more than 2.2 million people who reside in Seattle and 38 other municipalities. Participants: King County residents who were diagnosed with COVID-19 between July 2020 and June 2021. Intervention: The PHSKC integrated COVID-19 CI/CT with prevention education and service provision. Results:The PHSKC CI/CT team interviewed 42 900 cases (82% of cases eligible for CI/CT), a mean of 6.1 days after symptom onset and 3.4 days after SARS-CoV-2 testing. Cases disclosed the names and addresses of 10 817 unique worksites (mean = 0.8/interview) and 11 432 other recently visited locations (mean = 0.5/interview) and provided contact information for 62 987 household members (mean = 2.7/interview) and 14 398 nonhousehold contacts (mean = 0.3/interview). The CI/CT team helped arrange COVID-19 testing for 5650 contacts, facilitated grocery delivery for 7253 households, and referred 9127 households for financial assistance. End of I&Q Survey participants (n = 304, 54% of sampled) reported self-notifying an average of 4 nonhousehold contacts and 69% agreed that the information and referrals provided by the CI/CT team helped them stay in isolation. Conclusions: In the 12-month evaluation period, CI/CT reached 42 611 households and identified thousands of exposure venues. The timing of CI/CT relative to infectiousness and difficulty eliciting nonhousehold contacts may have attenuated the intervention's effect. Through promotion of I&Q guidance and services, CI/CT can help mitigate pandemic-related hardships.

Public Health 3.0 approaches are critical for monitoring disparities in economic, social, and overall health impacts following the COVID-19 pandemic and its associated policy changes to slow community spread. Timely, cross-sector data as identified using this approach help decisionmakers identify changes, track racial disparities, and address unintended consequences during a pandemic. We applied a monitoring and evaluation framework that combined policy changes with timely, relevant cross-sector data and community review. Indicators covered unemployment, basic needs, family violence, education, childcare, access to health care, and mental, physical, and behavioral health. In response to increasing COVID-19 cases, nonpharmaceutical intervention strategies were implemented in March 2020 in King County, Washington. By December 2020, 554 000 unemployment claims were filed. Social service calls increased 100%, behavioral health crisis calls increased 25%, and domestic violence calls increased 25%, with disproportionate impact on communities of color. This framework can be replicated by local jurisdictions to inform and address racial inequities in ongoing COVID-19 mitigation and recovery. Cross-sector collaboration between public health and sectors addressing the social determinants of health are an essential first step to have an impact on long-standing racial inequities.

Background Personal care products may contain many chemicals, some of which are suspected endocrine disrupters. This is an important source of chemical exposure for women, but little is known about how chemical exposure differs among different races/ethnicities. Objective This study examines differences in personal care product use among Black, Latina, Vietnamese, Mixed Race, and White women in California. Methods We used a community-based participatory process to create and administer a personal care product usage survey to 321 Black, Latina, Vietnamese, Mixed Race, and White women. We used multivariate regression models with pairwise comparisons to examine the frequency of product use by race/ethnicity. Results We found distinct trends of personal care product use by race/ethnicity: Latina women typically used makeup most frequently; Black women used certain hair products or styles most frequently; and Vietnamese women were most likely to use facial cleansing products compared to other races/ethnicities. Latina and Vietnamese women were less likely to try to avoid certain ingredients in their products. Significance These findings can help estimate disparities in chemical exposure from personal care product use and complement future research on health inequities due to chemical exposures in the larger environmental and social context.

Background The purpose of this study was to examine the association between perceived social support and postpartum depression symptoms (PDS) and to understand how this association may differ for urban, suburban, rural Appalachian, and rural non‐Appalachian women in Ohio. Methods Data were obtained via the 2016 Ohio Pregnancy Assessment Survey (n = 3382), a representative sample of postpartum women in Ohio. We conducted bivariate analyses to assess the associations between self‐perceived social support and PDS, and covariates. Univariate and multivariate logistic regressions were conducted using a modified Poisson distribution to estimate the association between social support and PDS, adjusting for sociodemographic characteristics. We also examined geographical context as an independent predictor of PDS and as an effect modifier for the association between social support and PDS. Results 15.6% of survey respondents experienced PDS. Women with low levels of social support had slightly higher prevalence (aPR: 1.4, 95% CI: 1.0‐2.1) of PDS compared to women with high social support. Geographic context was an independent predictor of PDS; women in rural Appalachia had significantly lower prevalence (aPR: 0.5, 95% CI: 0.2‐0.9) of PDS compared to women in urban areas. We did not find that geographical context modified the relationship between social support and PDS (Wald P = .5). Conclusions Low social support was associated with increased PDS but did not reach statistical significance. Women living in rural Appalachia had a lower prevalence of PDS. Future studies should explore the reasons for lower rates of PDS in rural Appalachia.
