Evaluation of School Wellness Policies in Low-Income California Districts After the 2016 USDA Final Rule.

BACKGROUND: Districts with federal nutrition programs must have an updated local school wellness policy (LSWP) to promote nutrition, physical activity, and student wellness. This study evaluates factors associated with LSWP quality among low-income districts. METHODS: In 2018, we collected LSWPs from websites of 200 randomly selected, county-stratified, low-income-serving California public districts. Multivariable linear regression assessed associations between district characteristics, model LSWP use (national, state, none), and adoption date on policy quality. RESULTS: On the WellSAT 3.0 scale of 0-100, mean (95% CI) comprehensiveness was 65.0 (63.2-66.7) and strength was 37.3 (35.3-39.2). Nearly verbatim adoption of model LSWPs was high (68.5% state model, 13.0% a national model). Half were adopted before mandated updates. District size (≥1000 students) and national model LSWP adoption were associated with higher comprehensive scores. National model LSWP adoption was associated with higher strength scores in updated policies compared with those not updated. IMPLICATIONS: LSWPs have improved school food and activity environments, but district engagement in LSWP is low. Integration into education frameworks that reduce learning barriers could provide synergy for re-engagement. CONCLUSIONS: High adoption of model policies and low update compliance indicate little district engagement in LSWP. Mixed methods studies of districts with high-quality LSWP are needed.

Spending by California's Department of Developmental Services for Persons with Autism across Demographic and Expenditure Categories.

BACKGROUND: Few autism spectrum disorder (ASD) studies have estimated non-medical costs for treatment or addressed possible differences in provision of services across gender, race-ethnic, age or demographic or expenditure categories, especially among adults. METHODS: The California Department of Developmental Services (CDDS) provides services to residents with developmental disabilities. CDDS provided aggregate data on primarily non-medical spending for fiscal year 2012-2013 for persons with ASD with or without intellectual disability (ID) (main sample, n = 42,274), and two sub-samples: ASD only (n = 30,164), and ASD+ID (n = 12,110). Demographic variables included sex, age and race-ethnicity. Spending categories included Employment Support, Community Care Facilities, Day Care, Transportation, and in-home and out-of-home Respite. RESULTS: Per-person spending for males and females were approximately the same: $10,488 and $10,791 for males and females for ages 3-17 and $26,491 and $26,627 for ages 18+. Among race/ethnicity categories, the ranking from highest to lowest among ages 3-17 was white non-Hispanics ($11,480), Asian non-Hispanics ($11,036), "Others" ($11,031), Hispanics ($9,571), and African-American non-Hispanics ($9,482). For ages 18+, the ranking was whites ($31,008), African-Americans ($26,831), "Others" ($25,395), Asians ($22,993), and Hispanics ($18,083). The ASD+ID sub-sample exerted disproportionate influence on findings from the main sample for persons 18+. Combining all ages, the top two expenditure categories for per-person spending were Community Care Facilities ($43,867) and Day Care ($11,244). For most adult age groups, the percentage of recipients participating were highest for Day Care (44.9% - 62.4%) and Transportation (38.6% - 50.9%). Per-person spending for Day Care, Transportation, and Employment Support was relatively low for children but relatively high for adults. CONCLUSION: White non-Hispanics received the highest per-person spending and Hispanics among the least. Amounts within spending categories varied considerably across age groups. Our estimates may be useful as baseline measures for stakeholders preparing for increasing ASD prevalence, especially among adults.

The effects of nutrition knowledge on food label use. A review of the literature.

Nutrition information on food labels is an important source of nutrition information but is typically underutilized by consumers. This review examined whether consumer nutrition knowledge is important for communication of nutrition information through labels on packaged foods. A cognitive processing model posits that consumers with prior knowledge are more likely to use label information effectively, that is, focus on salient information, understand information, and make healthful decisions based on this information. Consistent with this model, the review found that nutrition knowledge provides support for food label use. However, nutrition knowledge measures varied widely in terms of the dimensions they included and the extensiveness of the assessment. Relatively few studies investigated knowledge effects on the use of ingredient lists and claims, compared to nutrition facts labels. We also found an overreliance on convenience samples relying on younger adults, limiting our understanding of how knowledge supports food label use in later life. Future research should 1) investigate which dimensions, or forms, of nutrition knowledge are most critical to food label use and dietary decision making and 2) determine whether increases in nutrition knowledge can promote great use of nutrition information on food labels.

Misunderstanding of Front-Of-Package Nutrition Information on US Food Products.

Front-of-package nutrition symbols (FOPs) are presumably readily noticeable and require minimal prior nutrition knowledge to use. Although there is evidence to support this notion, few studies have focused on Facts Up Front type symbols which are used in the US. Participants with varying levels of prior knowledge were asked to view two products and decide which was more healthful. FOPs on packages were manipulated so that one product was more healthful, allowing us to assess accuracy. Attention to nutrition information was assessed via eye tracking to determine what if any FOP information was used to make their decisions. Results showed that accuracy was below chance on half of the comparisons despite consulting FOPs. Negative correlations between attention to calories, fat, and sodium and accuracy indicated that consumers over-relied on these nutrients. Although relatively little attention was allocated to fiber and sugar, associations between attention and accuracy were positive. Attention to vitamin D showed no association to accuracy, indicating confusion surrounding what constitutes a meaningful change across products. Greater nutrition knowledge was associated with greater accuracy, even when less attention was paid. Individuals, particularly those with less knowledge, are misled by calorie, sodium, and fat information on FOPs.

Relationships among food label use, motivation, and dietary quality.

Nutrition information on packaged foods supplies information that aids consumers in meeting the recommendations put forth in the US Dietary Guidelines for Americans such as reducing intake of solid fats and added sugars. It is important to understand how food label use is related to dietary intake. However, prior work is based only on self-reported use of food labels, making it unclear if subjective assessments are biased toward motivational influences. We assessed food label use using both self-reported and objective measures, the stage of change, and dietary quality in a sample of 392 stratified by income. Self-reported food label use was assessed using a questionnaire. Objective use was assessed using a mock shopping task in which participants viewed food labels and decided which foods to purchase. Eye movements were monitored to assess attention to nutrition information on the food labels. Individuals paid attention to nutrition information when selecting foods to buy. Self-reported and objective measures of label use showed some overlap with each other (r=0.29, p<0.001), and both predicted dietary quality (p<0.001 for both). The stage of change diminished the predictive power of subjective (p<0.09), but not objective (p<0.01), food label use. These data show both self-reported and objective measures of food label use are positively associated with dietary quality. However, self-reported measures appear to capture a greater motivational component of food label use than do more objective measures.

Building research capacity with members of underserved American Indian/Alaskan Native communities: training in research ethics and the protection of human subjects.

OBJECTIVE: To develop a research ethics training course for American Indian/Alaskan Native health clinic staff and community researchers who would be conducting human subjects research. METHOD: Community-based participatory research methods were used in facilitated discussions of research ethics centered around topics included in the Collaborative Institutional Training Initiative research ethics course. RESULTS: The community-based participatory research approach allowed all partners to jointly develop a research ethics training program that was relevant for American Indian/Alaskan Native communities. All community and clinic partners were able to pass the Collaborative Institutional Training Initiative course they were required to pass so that they could be certified to conduct research with human subjects on federally funded projects. In addition, the training sessions provided a foundation for increased community oversight of research. CONCLUSIONS: By using a collaborative process to engage community partners in research ethics discussions, rather than either an asynchronous online or a lecture/presentation format, resulted in significant mutual learning about research ethics and community concerns about research. This approach requires university researchers to invest time in learning about the communities in which they will be working prior to the training.

Evaluating local policy adoption campaigns in California: Tobacco Retail License (TRL) adoption.

As part of its state-wide "denormalization" campaign, the California Tobacco Control Program has funded local tobacco control projects to secure tobacco retail licenses (TRLs) in their communities. TRL policies generate funding by requiring tobacco retailers within a jurisdiction to obtain a license, which is in addition to the state license that tobacco retailers are legally required to purchase to sell tobacco products. The funding provided by TRLs enables local law enforcement to carry out inspection and enforcement operations. This paper examines the unique processes by which local project campaigns attempt to get TRL policies adopted in communities across the State of California. Twenty-two local projects submitted final evaluation reports pertaining to the adoption of TRLs, and the reports from these projects form the basis of the analysis. Successful campaigns tended to include the following strategies: (1) determining policy readiness; (2) gathering local data; (3) identifying and working with a "champion"; (4) building relationships with local law enforcement agencies and decision makers; and (5) educating community and decision makers. The major challenges faced by local projects included budget cuts and staffing issues, concern about creating an unfavorable environment for business by imposing more regulations and fees, and complaints about using law enforcement resources for tobacco control in light of more "pressing" public safety issues. These challenges proved difficult for local projects to overcome, and also highlight the need for projects to create and carry out strong but flexible tactical plans that incorporate the aforementioned strategies.

A qualitative evaluation of 40 voluntary, smoke-free, multiunit, housing policy campaigns in California.

BACKGROUND: Although it is legal for multiunit housing (MUH) property owners in all 50 states to prohibit smoking on their premises, including in individual units, MUH constitutes a relatively new setting to reduce exposure to secondhand smoke via voluntary smoke-free policy. This paper examines California state-funded smoke-free MUH policy campaigns between 2004 and 2010. METHODS: A cross-case analysis of 40 state-funded smoke-free MUH policy campaigns was conducted via an examination of final evaluation reports submitted to the California Tobacco Control Program. RESULTS: The most effective voluntary smoke-free MUH policy campaigns typically included: (1) learning the local [MUH] context, (2) finding and using a champion, (3) partnering with like-minded organisations, (4) building relationships with stakeholders, (5) collecting and using local data and (6) making a compelling case to decision makers. DISCUSSIONS: The aforementioned steps tended to be intertwined, and successfully securing voluntary smoke-free MUH policy required a strategic but flexible plan of implementation prior to entrance into the field. Campaigns designed to enhance voluntary smoke-free MUH policy adoption should underscore the economic viability of such policies during each strategic step.

Development of Time-location Weighted Spatial Measures Using Global Positioning System Data.

OBJECTIVES: Despite increasing availability of global positioning system (GPS), no research has been conducted to analyze GPS data for exposure opportunities associated with time at indoor and outdoor microenvironments. We developed location-based and time-weighted spatial measures that incorporate indoor and outdoor time-location data collected by GPS. METHODS: Time-location data were drawn from 38 female subjects in California who wore a GPS device for seven days. Ambient standard deviational ellipse was determined based on outdoor locations and time duration, while indoor time weighted standard deviational ellipse (SDE) was developed to incorporate indoor and outdoor times and locations data into the ellipse measure. RESULTS: Our findings indicated that there was considerable difference in the sizes of exposure potential measures when indoor time was taken into consideration, and that they were associated with day type (weekday/weekend) and employment status. CONCLUSIONS: This study provides evidence that time-location weighted measure may provide better accuracy in assessing exposure opportunities at different microenvironments. The use of GPS likely improves the geographical details and accuracy of time-location data, and further development of such location-time weighted spatial measure is encouraged.

Accommodating diverse clients' needs in evaluation capacity building: a case study of the Tobacco Control Evaluation Center.

In this case study, we detail and analyze how the Tobacco Control Evaluation Center (TCEC), an evaluation technical assistance center that serves approximately 100 local tobacco control organizations in California, endeavors to build capacity among the state-funded local providers it serves by using evaluation capacity building activities with an utilization-focused evaluation framework. We call this a "blended approach" and describe these methods. Satisfaction and demand for TCEC services are documented to provide measurements for evaluation capacity building. Final evaluation report scores from two intervention cycles (2004-2007 and 2007-2010) submitted to the California Health Department, Tobacco Control Division are also assessed and compared. These measures demonstrate an increase in evaluation capacity by local projects under TCEC's purview.

Navigating local smoke-free multi-unit housing policy adoption.

California state-funded local tobacco control projects have instituted smoke-free multi-unit housing (MUH) policy adoption campaigns in order to secure voluntary policy throughout the state. While landlords can legally prohibit smoking at MUH complexes in California, they often oppose such measures. The objective of this study was to analyze voluntary smoke-free policy campaigns of state-funded local projects by focusing on the challenges they faced. Specifically, we examined 40 local campaigns in California led by county health departments and community based organizations, focusing on the barriers the local projects often had to overcome to enact policy. Our results identify arguments and issues typically raised by MUH property landlords, including the notion of tenant smoker and privacy rights, potential negative effects of smoke-free policy, and issues concerning the enforcement of policy. Moreover, relationships between local project personnel and MUH management often soured, which sometimes derailed smoke-free policy campaigns altogether. Our findings provide agencies with insights from the MUH property landlord perspective that will serve to inform future campaign strategy.

Cancer and non-cancer health effects from food contaminant exposures for children and adults in California: a risk assessment.

BACKGROUND: In the absence of current cumulative dietary exposure assessments, this analysis was conducted to estimate exposure to multiple dietary contaminants for children, who are more vulnerable to toxic exposure than adults. METHODS: We estimated exposure to multiple food contaminants based on dietary data from preschool-age children (2-4 years, n=207), school-age children (5-7 years, n=157), parents of young children (n=446), and older adults (n=149). We compared exposure estimates for eleven toxic compounds (acrylamide, arsenic, lead, mercury, chlorpyrifos, permethrin, endosulfan, dieldrin, chlordane, DDE, and dioxin) based on self-reported food frequency data by age group. To determine if cancer and non-cancer benchmark levels were exceeded, chemical levels in food were derived from publicly available databases including the Total Diet Study. RESULTS: Cancer benchmark levels were exceeded by all children (100%) for arsenic, dieldrin, DDE, and dioxins. Non-cancer benchmarks were exceeded by >95% of preschool-age children for acrylamide and by 10% of preschool-age children for mercury. Preschool-age children had significantly higher estimated intakes of 6 of 11 compounds compared to school-age children (p<0.0001 to p=0.02). Based on self-reported dietary data, the greatest exposure to pesticides from foods included in this analysis were tomatoes, peaches, apples, peppers, grapes, lettuce, broccoli, strawberries, spinach, dairy, pears, green beans, and celery. CONCLUSIONS: Dietary strategies to reduce exposure to toxic compounds for which cancer and non-cancer benchmarks are exceeded by children vary by compound. These strategies include consuming organically produced dairy and selected fruits and vegetables to reduce pesticide intake, consuming less animal foods (meat, dairy, and fish) to reduce intake of persistent organic pollutants and metals, and consuming lower quantities of chips, cereal, crackers, and other processed carbohydrate foods to reduce acrylamide intake.

Making healthy food choices using nutrition facts panels. The roles of knowledge, motivation, dietary modifications goals, and age.

Nutrition facts panels (NFPs) contain a rich assortment of nutrition information and are available on most food packages. The importance of this information is potentially even greater among older adults due to their increased risk for diet-related diseases, as well as those with goals for dietary modifications that may impact food choice. Despite past work suggesting that knowledge and motivation impact attitudes surrounding and self-reported use of NFPs, we know little about how (i.e., strategies used) and how well (i.e., level of accuracy) younger and older individuals process NFP information when evaluating healthful qualities of foods. We manipulated the content of NFPs and, using eye tracking methodology, examined strategies associated with deciding which of two NFPs, presented side-by-side, was healthier. We examined associations among strategy use and accuracy as well as age, dietary modification status, knowledge, and motivation. Results showed that, across age groups, those with dietary modification goals made relatively more comparisons between NFPs with increasing knowledge and motivation; but that strategy effectiveness (relationship to accuracy) depended on age and motivation. Results also showed that knowledge and motivation may protect against declines in accuracy in later life and that, across age and dietary modification status, knowledge mediates the relationship between motivation and decision accuracy.

Feasibility of using web surveys to collect time-activity data.

Time-activity data are traditionally collected by telephone interviews or through paper diaries, which are time consuming and costly. As a potential alternative that may greatly save staff time, a web survey to collect time-activity data was developed and tested in this study. We collected 24-h recall web diaries from 151 parents of young children mostly under 55 years of age (who also answered for their children) and 55 older adults (≥ 55 years of age) both on a weekday and a weekend day every 3 months during an 18-month period. The performance and reliability of the web surveys collected were evaluated, including the survey-completion rate, and the percentage of surveys with unreasonable time being reported as spent sleeping and with missing reports of being in transit between locations. We also compared the web-survey data with time-activity information we collected from the same subjects in telephone interviews and found that these data sources were fairly consistent with each other. However, we observed slightly more compliance issues for the web than the telephone survey, but most of these issues could be addressed and minimized by refining some questions or the survey interface. Our study suggests that it is critical to reduce participants' burden and improve survey interface design for optimal compliance and data quality. In conclusion, web surveys are a promising method to consider for time-activity data collection.

Passive sampling methods to determine household and personal care product use.

Traditionally, use of household and personal care products has been collected through questionnaires, which is very time consuming, a burden on participants, and prone to recall bias. As part of the SUPERB Project (Study of Use of Products and Exposure-Related Behaviors), a novel platform was developed using bar codes to quickly and reliably determine what household and personal care products people have in their homes and determine the amount used over a 1-week period. We evaluated the acceptability and feasibility of our methodology in a longitudinal field study that included 47 California households, 30 with young children and 17 with an older adult. Acceptability was defined by refusal rates; feasibility was evaluated in terms of readable bar codes, useful product information in our database for all readable barcodes, and ability to find containers at both the start and end of the week. We found 63% of personal care products and 87% of the household care products had readable barcodes with 47% and 41% having sufficient data for product identification, respectively and secondly, the amount used could be determined most of the time. We present distributions for amount used by product category and compare inter- and intra-person variability. In summary, our method appears to be appropriate, acceptable, and useful for gathering information related to potential exposures stemming from the use of personal and household care products. A very low drop-out rate suggests that this methodology can be useful in longitudinal studies of exposure to household and personal care products.

Pandemics and vaccines: perceptions, reactions, and lessons learned from hard-to-reach Latinos and the H1N1 campaign.

This paper examines knowledge, risk perception, and attitudes around the H1N1 pandemic among Latino hard-to-reach (HTR) populations in the United States. Ten focus groups were conducted throughout California (N=90), representing Latino immigrants disproportionately affected by H1N1: farmworkers, indigenous Mexicans, pregnant women, and children. Overall, participants were aware of the H1N1 epidemic and common prevention practices. However, many expressed doubts that the H1N1 outbreak constituted an epidemic because the U.S. media reports of the epidemic in Mexico did not match reports from participants' families in Mexico and because of participants' absence of personal experience with the disease. Participants mistrusted the H1N1 vaccine due to its novelty, conspiracy theories, and inconsistent information. Study findings confirm that vaccination campaign strategies should reflect the diversity of meaning, experiences, and socio-economic realities among target populations. Key findings inform future emergency response activities targeting HTR Latino communities.

Building the evaluation capacity of California's local tobacco control programs.

Successful evaluation capacity building requires a dynamic balance between responding to local agency needs and ensuring that local staff have appropriate skills to conduct rigorous evaluations. In 2004, the California Tobacco Control Program established the Tobacco Control Evaluation Center (TCEC), based at a public research university, to provide evaluation technical assistance to approximately 100 local agencies implementing tobacco control programs. TCEC has been responsive to local needs, for instance, by answering 512 technical assistance requests in the first 5 years of operation and by tailoring training according to needs assessment results. About 50% of the technical assistance requests were for new data collection instruments (n = 255). TCEC has sought proactively to improve local evaluation skills, most recently in a data analysis and report writing skill building campaign that included a webinar, newsletter, and seven regional training meetings. Preliminary analysis suggests a 20% improvement in scores for the local final evaluation reports as a result of this campaign. It is concluded that evaluation technical assistance can be provided effectively by a university as long as the local context is kept in mind, and a balance of responsive and proactive technical assistance is provided.

Longitudinal variability of time-location/activity patterns of population at different ages: a longitudinal study in California.

BACKGROUND: Longitudinal time-activity data are important for exposure modeling, since the extent to which short-term time-activity data represent long-term activity patterns is not well understood. This study was designed to evaluate longitudinal variations in human time-activity patterns. METHOD: We report on 24-hour recall diaries and questionnaires collected via the internet from 151 parents of young children (mostly under age 55), and from 55 older adults of ages 55 and older, for both a weekday and a weekend day every three months over an 18-month period. Parents also provided data for their children. The self-administrated diary and questionnaire distinguished ~30 frequently visited microenvironments and ~20 activities which we selected to represent opportunities for exposure to toxic environmental compounds. Due to the non-normal distribution of time-location/activity data, we employed generalized linear mixed-distribution mixed-effect models to examine intra- and inter-individual variations. Here we describe variation in the likelihood of and time spent engaging in an activity or being in a microenvironment by age group, day-type (weekday/weekend), season (warm/cool), sex, employment status, and over the follow-up period. RESULTS: As expected, day-type and season influence time spent in many location and activity categories. Longitudinal changes were also observed, e.g., young children slept less with increasing follow-up, transit time increased, and time spent on working and shopping decreased during the study, possibly related to human physiological changes with age and changes in macro-economic factors such as gas prices and the economic recession. CONCLUSIONS: This study provides valuable new information about time-activity assessed longitudinally in three major age groups and greatly expands our knowledge about intra- and inter-individual variations in time-location/activity patterns. Longitudinal variations beyond weekly and seasonal patterns should be taken into account in simulating long-term time-activity patterns in exposure modeling.

Strategies implemented by 20 local tobacco control agencies to promote smoke-free recreation areas, California, 2004-2007.

INTRODUCTION: Since 2000, local jurisdictions in California have enacted hundreds of policies and ordinances in an effort to protect their citizens from the harmful effects of secondhand smoke. We evaluated strategies used by state-funded local tobacco control programs to enact local smoke-free policies involving outdoor recreational spaces. METHODS: The Tobacco Control Evaluation Center analyzed 23 final evaluation reports that discussed adopting local smoke-free policies in outdoor recreational facilities in California. These reports were submitted for the 2004 through 2007 funding period by local tobacco control organizations to the California Department of Public Health, Tobacco Control Program. We used a comparative technique whereby we coded passages and compared them by locale and case, focusing on strategies that led to the enactment of smoke-free policies. RESULTS: Our analysis found the following 6 strategies to be the most effective: 1) having a "champion" who helps to carry an objective forward, 2) tapping into a pool of potential youth volunteers, 3) collecting and using local data as a persuasive tool, 4) educating the community in smoke-free policy efforts, 5) working strategically in the local political climate, and 6) framing the policy appropriately. CONCLUSION: These strategies proved effective regardless of whether policies were voluntary, administrative, or legislative. Successful policy enactment required a strong foundation of agency funding and an experienced and committed staff. These results should be relevant to other tobacco control organizations that are attempting to secure local smoke-free policy.
