Health effects of the 2003 Southern California wildfires on children.

ABSTRACT:

Rationale

In late October 2003, Southern California wildfires burned more than 3,000 km2. The wildfires produced heavy smoke that affected several communities participating in the University of Southern California Children's Health Study (CHS).

Objectives

To study the acute effects of fire smoke on the health of CHS participants.

Methods

A questionnaire was used to assess smoke exposure and occurrence of symptoms among CHS high-school students (n = 873; age, 17-18 yr) and elementary-school children (n = 5,551; age, 6-7 yr), in a total of 16 communities. Estimates of particulate matter (PM10) concentrations during the 5 d with the highest fire activity were used to characterize community smoke level.

Main results

All symptoms (nose, eyes, and throat irritations; cough; bronchitis; cold; wheezing; asthma attacks), medication usage, and physician visits were associated with individually reported exposure differences within communities. Risks increased monotonically with the number of reported smoky days. For most outcomes, reporting rates between communities were also associated with the fire-related PM10 levels. Associations tended to be strongest among those without asthma. Individuals with asthma were more likely to take preventive action, such as wearing masks or staying indoors during the fire.

Conclusions

Exposure to wildfire smoke was associated with increased eye and respiratory symptoms, medication use, and physician visits.

Project description:There is limited information on the public health impact of wildfires. The relationship of cardiorespiratory hospital admissions (n = 40 856) to wildfire-related particulate matter (PM(2.5)) during catastrophic wildfires in southern California in October 2003 was evaluated.Zip code level PM(2.5) concentrations were estimated using spatial interpolations from measured PM(2.5), light extinction, meteorological conditions, and smoke information from MODIS satellite images at 250 m resolution. Generalised estimating equations for Poisson data were used to assess the relationship between daily admissions and PM(2.5), adjusted for weather, fungal spores (associated with asthma), weekend, zip code-level population and sociodemographics.Associations of 2-day average PM(2.5) with respiratory admissions were stronger during than before or after the fires. Average increases of 70 microg/m(3) PM(2.5) during heavy smoke conditions compared with PM(2.5) in the pre-wildfire period were associated with 34% increases in asthma admissions. The strongest wildfire-related PM(2.5) associations were for people ages 65-99 years (10.1% increase per 10 microg/m(3) PM(2.5), 95% CI 3.0% to 17.8%) and ages 0-4 years (8.3%, 95% CI 2.2% to 14.9%) followed by ages 20-64 years (4.1%, 95% CI -0.5% to 9.0%). There were no PM(2.5)-asthma associations in children ages 5-18 years, although their admission rates significantly increased after the fires. Per 10 microg/m(3) wildfire-related PM(2.5), acute bronchitis admissions across all ages increased by 9.6% (95% CI 1.8% to 17.9%), chronic obstructive pulmonary disease admissions for ages 20-64 years by 6.9% (95% CI 0.9% to 13.1%), and pneumonia admissions for ages 5-18 years by 6.4% (95% CI -1.0% to 14.2%). Acute bronchitis and pneumonia admissions also increased after the fires. There was limited evidence of a small impact of wildfire-related PM(2.5) on cardiovascular admissions.Wildfire-related PM(2.5) led to increased respiratory hospital admissions, especially asthma, suggesting that better preventive measures are required to reduce morbidity among vulnerable populations.

Project description:Colorectal cancer (CRC) screening can reduce cancer deaths. However, screening and abnormal test follow-up rates are low among underserved populations. The screening rates of 19-58%, and rates of colonoscopy completion after abnormal stool tests of 18-57% in community health centers (CHC) systems are low. This highlights an opportunity to improve early detection and decrease burden of CRC in our region. Mailed outreach and navigation programs have been shown to increase colonoscopy completion rate. The next step is to understand how to best implement these programs in the community on a larger scale. To achieve this goal, the investigators propose a Hub-and-Spoke intervention combining centralized strategies to maximize CRC screening, follow-up, and referral-to-care. The investigators hypothesize that this intervention will be superior to usual care for increasing CRC screening, abnormal test follow-up, and referral-to-care. The investigators will conduct a randomized trial to determine effectiveness in: 1) improvement in proportion of individuals up-to-date with screening 3 years post implementation; 2) proportion with abnormal FIT who complete diagnostic colonoscopy within 6 months; and 3) proportion with CRC completing first treatment evaluation. The investigators will also evaluate the implementation, scalability, and sustainability of the multi-level implementation strategy. The intervention consists of: Mailed FIT and Reminders. Eligible individuals will receive an introductory letter describing the importance of CRC screening and noting that follow-up mail will include a FIT Kit. It will also be offered to patients who completed prior mailed FIT with normal test results. All materials will be in English and Spanish. Two weeks later, participants will receive a packet via mail containing the FIT kit, a one-page invitation inviting FIT completion and FIT instructions, a postage-paid envelope for return to the patient’s CHC, and COVID-19 message. For non-compliant individuals not returning the kit, a reminder phone call and text message will be delivered 2 weeks later. The investigators will track returned letters, individuals who are later found to be up-to date with screening, and those who decline screening. The CHC will provide care coordination for patients with an abnormal FIT result.

Project description:ImportanceResearch in the early 2000s in California demonstrated that racial and ethnic minorities, immigrants, and those with limited English proficiency (LEP) experienced high rates of discrimination in health care. Less is known about how patients' perceptions of discrimination in health care have changed since then.ObjectiveTo determine whether perceptions of discrimination in health care have changed overall and for specific vulnerable populations.Design, setting, and participantsThis cross-sectional study used data from the California Health Interview Survey for state residents aged 18 years and older for 2 periods, 2003 to 2005 and 2015 to 2017. χ2 analyses and multivariate logistic regression were performed to compare recent discrimination in health care in late vs early periods controlling for race/ethnicity, poverty level, education, insurance status, usual source of care, self-reported health, and LEP. Additional subanalyses were performed by race/ethnicity, immigrant status, and LEP status. Jackknife replicate weights were provided by the California Health Interview Survey.ExposureSurvey year was dichotomized as combined 2003 to 2005 and combined 2015 to 2017.Main outcomes and measuresSurvey respondents were identified as having experienced recent discrimination in health care if they responded "yes" to the question, "Was there ever a time when you would have gotten better medical care if you had belonged to a different race or ethnic group?" and reported that this occurred within the last 5 years.ResultsThere were 84 088 participants in 2003 to 2005 (51.0% female; 14.7% aged ≥65 years) and 63 242 participants in 2015 to 2017 (51.1% female; 18.0% aged ≥65 years). Rates of recent discrimination in health care decreased from 6.0% to 4.0% (difference, 2.0%; 95% CI, 1.5%-2.5%; P < .001). In adjusted analyses, perceptions of discrimination in health care decreased in 2015 to 2017 compared with 2003 to 2005 (odds ratio [OR], 0.60; 95% CI, 0.53-0.68; P < .001). There was a significant race × period interaction for Latino individuals (OR, 0.58; 95% CI, 0.40-0.83; P = .003) but not for Asian individuals (OR, 0.76; 95% CI, 0.50-1.16; P = .20) or African American individuals (OR, 1.24; 95% CI, 0.76-2.02; P = .40). There was a significant immigrant status × period interaction (OR, 0.55; 95% CI, 0.44-0.69; P < .001) and LEP status × period interaction (OR, 0.67; 95% CI, 0.51-0.89; P < .001).Conclusions and relevanceThis study suggests that perceptions of discrimination in health care in California decreased between 2003 to 2005 and 2015 to 2017 among Latino individuals, immigrants, and those with LEP. African American participants reported consistently high rates of discrimination, indicating that interventions targeting health care discrimination are still necessary.
