Racial and Socioeconomic Disparities in Preconception Health Risk Factors and Access to Care.

Background: Black birthing people have significantly higher risks of maternal mortality and morbidity compared with White people. Preconception chronic conditions increase the risk of adverse pregnancy outcomes, yet little is known about disparities in preconception health. This study applies an intersectional framework to examine the simultaneous contributions of racial marginalization and economic deprivation in determining disparities in preconception risk factors and access to care. Methods: Using data from the Pregnancy Risk Assessment Monitoring System, 2016-2020 (N = 123,697), we evaluated disparities by race and income in self-reported preconception hypertension, diabetes, obesity, depression, and smoking, as well as preconception insurance coverage and utilization of health care. We estimated linear regression models and calculated predicted probabilities. Results: Black respondents experienced higher probabilities of preconception obesity and high blood pressure at every income level compared with White respondents. Higher income did not attenuate the probability of obesity for Black respondents (linear trend p = 0.21), as it did for White respondents (p < 0.001). Conversely, while White respondents with low income were at higher risk of preconception depression and smoking than their Black counterparts, higher income was strongly associated with reduced risk, with significantly steeper reductions for White compared with Black respondents (difference in trends p < 0.001 for both risk factors). White respondents had higher probabilities of utilizing preconception care across all income levels, despite similar probabilities of insurance coverage. Conclusions: Higher income does not protect against the risk of preconception obesity and other preconception risk factors for Black birthing people as it does for White birthing people. Results point to the need to consider multiple forms of intersecting structural factors in policy and intervention research to improve preconception and maternal health.

Validity of Self-Reported Tobacco Smoke Exposure among Non-Smoking Adult Public Housing Residents.

INTRODUCTION: Tobacco smoke exposure (TSE) in public multi-unit housing (MUH) is of concern. However, the validity of self-reports for determining TSE among non-smoking residents in such housing is unclear. METHODS: We analyzed data from 285 non-smoking public MUH residents living in non-smoking households in the Boston area. Participants were interviewed about personal TSE in various locations in the past 7 days and completed a diary of home TSE for 7 days. Self-reported TSE was validated against measurable saliva cotinine (lower limit of detection (LOD) 0.02 ng/ml) and airborne apartment nicotine (LOD 5 ng). Correlations, estimates of inter-measure agreement, and logistic regression assessed associations between self-reported TSE items and measurable cotinine and nicotine. RESULTS: Cotinine and nicotine levels were low in this sample (median = 0.026 ng/ml and 0.022 µg/m(3), respectively). Prevalence of detectable personal TSE was 66.3% via self-report and 57.0% via measurable cotinine (median concentration among those with cotinine>LOD: 0.057 ng/ml), with poor agreement (kappa = 0.06; sensitivity = 68.9%; specificity = 37.1%). TSE in the home, car, and other peoples' homes was weakly associated with cotinine levels (Spearman correlations rs = 0.15-0.25), while TSE in public places was not associated with cotinine. Among those with airborne nicotine and daily diary data (n = 161), a smaller proportion had household TSE via self-report (41.6%) compared with measurable airborne nicotine (53.4%) (median concentration among those with nicotine>LOD: 0.04 µg/m(3)) (kappa = 0.09, sensitivity = 46.5%, specificity = 62.7%). CONCLUSIONS: Self-report alone was not adequate to identify individuals with TSE, as 31% with measurable cotinine and 53% with measurable nicotine did not report TSE. Self-report of TSE in private indoor spaces outside the home was most associated with measurable cotinine in this low-income non-smoking population.

Assessment of Residents' Attitudes and Satisfaction Before and After Implementation of a Smoke-Free Policy in Boston Multiunit Housing.

INTRODUCTION: In 2012, the Boston Housing Authority (BHA) in Massachusetts implemented a smoke-free policy prohibiting smoking within its residences. We sought to characterize BHA resident experiences before and after the smoke-free policy implementation, and compare them to that of nearby residents of the Cambridge Housing Authority, which had no such policy. METHODS: We recruited a convenience sample of nonsmoking residents from the BHA and Cambridge Housing Authority. We measured residents' awareness and support of their local smoking policies before and 9-12 months after the BHA's policy implementation, as well as BHA respondents' attitudes towards the smoke-free policy. We assessed tobacco smoke exposure via saliva cotinine, airborne apartment nicotine, and self-reported number of days smelling smoke in the home. We evaluated predictors of general satisfaction at follow-up using linear regression. RESULTS: At follow-up, 91% of BHA respondents knew that smoking was not allowed in apartments and 82% were supportive of such a policy in their building. BHA residents believed enforcement of the smoke-free policy was low. Fifty-one percent of BHA respondents indicated that other residents "never" or "rarely" followed the new smoke-free rule and 41% of respondents were dissatisfied with policy enforcement. Dissatisfaction with enforcement was the strongest predictor of general housing satisfaction, while objective and self-reported measures of tobacco smoke exposure were not predictive of satisfaction. At follow-up, 24% of BHA participants had complained to someone in charge about policy violations. CONCLUSIONS: Resident support for smoke-free policies is high. However, lack of enforcement of smoke-free policies may cause frustration and resentment among residents, potentially leading to a decrease in housing satisfaction. IMPLICATIONS: Smoke-free housing laws are becoming increasingly prevalent, yet little is known about satisfaction and compliance with such policies post-implementation. We evaluated nonsmoking residents' attitudes about smoke-free rules and their satisfaction with enforcement 1 year after the BHA implemented its comprehensive smoke-free policy. We found that while residents were supportive of the policy, they believed enforcement was low, a perception that was associated with a drop in housing satisfaction. Our findings point to a desire for smoke-free housing among public housing residents, and the importance of establishing systems and guidelines to help landlords monitor and enforce these policies effectively.
