Project description:IntroductionIn the U.S., children regularly consume foods from quick-service restaurants, but little is known about the marketing strategies currently used inside quick-service restaurants. This study aims to validate a child-focused Environmental Assessment Tool for quick-service restaurants, evaluate marketing strategies inside and on the exterior of quick-service restaurants, and examine differences by community race/ethnicity or income.MethodsThe inter-rater and test-retest reliability of the Environmental Assessment Tool were assessed across the top 5 national quick-service restaurant chains. Marketing techniques in 165 quick-service restaurants (33 per national chain) in socioeconomically and racially/ethnically diverse communities throughout New England were examined in 2018-2019. Mixed methods ANOVA examined the differences in marketing techniques in 2020.ResultsThe inter-rater and test-retest reliability of the Environmental Assessment Tool were high (Cohen's κ>0.80). Approximately 95% of quick-service restaurants marketed less healthy foods, whereas only 6.5% marketed healthy options. When examining the differences by community demographics, there were significantly more price promotion advertisements inside and on the exterior of quick-service restaurants in lower-income communities. In addition, there was a greater number of child-directed advertisements with cartoon or TV/movie characters as well as fewer healthy entrée options and more sugar-sweetened beverage and dessert options on the children's menu inside quick-service restaurants in communities with higher minority populations.ConclusionsEnvironmental Assessment Tool is a valid tool to evaluate marketing inside quick-service restaurants. Results suggest that there is a substantial amount of unhealthy food and beverage marketing inside quick-service restaurants, with differences in the number and types of techniques used in lower-income and minority communities. Policies that limit quick-service restaurant marketing to children should be considered.

Project description:ObjectiveTo evaluate the impact of a model of rural community health service (CHS) on the use and acceptability of primary healthcare services.DesignQuasi-experimental.SettingTwo adjacent rural counties in China.Participants5842 residents in 2009 and 3807 in 2010 from 980 households in 7 intervention townships and 49 villages; 2232 residents in 2009 and 2315 in 2010 from 628 households in 3 comparison townships and 9 villages. All residents were approached to participate, with no significant differences in age or sex between groups.InterventionMultilevel intervention in 2009 including training rural practitioners, encouraging clinic improvements, providing clinical guidelines, standards and subsidies.Data collectionSurveys of community members from randomly sampled households in 2009 and 2010.Primary outcome measuresSatisfaction with and utilisation of outpatient and public health services.AnalysisFactor analysis confirmed two components of satisfaction. Univariate and multilevel analysis was used.ResultsSatisfaction scores for intervention county respondents increased from 21.4 (95% CI 21.1 to 21.7) to 22.1 (95% CI 21.7 to 22.4) with no change in comparison area. In multilevel analysis, satisfaction with patient-centred care was associated with chronic disease, shorter waiting times and county. Satisfaction with clinic environment and cost was associated with female gender, shorter waiting times but not county. The proportion of children receiving immunisation in intervention village clinics increased from 42.5% (95% CI 27.9% to 47.1%) to 59.2% (95% CI 53.8% to 64.6%) whereas this decreased in comparison villages (16.5%; 95% CI 10.3% to 22.7% to 6.0%; 95% CI 1.3% to 10.7%). Antenatal visits increased in intervention villages (from 69.0%, 95% CI 65.8% to 73.1% to 75.8%, 95% CI 72.2% to 79.4%) with no change in comparison villages.ConclusionsIntroduction of a CHS model adapted to economically less-developed rural areas was associated with some improvements in satisfaction with care and use of some village-based public health services. Further research is needed to determine its public health impact and application to other areas.

Project description:We investigated if geologic factors are linked to elevated arsenic (As) concentrations above 5 μg/L in well water in the state of Virginia, USA. Using geologic unit data mapped within GIS and two datasets of measured As concentrations in well water (one from public wells, the other from private wells), we evaluated occurrences of elevated As (above 5 μg/L) based on geologic unit. We also constructed a logistic regression model to examine statistical relationships between elevated As and geologic units. Two geologic units, including Triassic-aged sedimentary rocks and Triassic-Jurassic intrusives of the Culpeper Basin in north-central Virginia, had higher occurrences of elevated As in well water than other geologic units in Virginia. Model results support these patterns, showing a higher probability for As occurrence above 5 μg/L in well water in these two units. Due to the lack of observations (<5%) having elevated As concentrations in our data set, our model cannot be used to predict As concentrations in other parts of the state. However, our results are useful for identifying areas of Virginia, defined by underlying geology, that are more likely to have elevated As concentrations in well water. Due to the ease of obtaining publicly available data and the accessibility of GIS, this study approach can be applied to other areas with existing datasets of As concentrations in well water and accessible data on geology.

Project description:Previous evidence has identified potential racial disparities in access to community water and sewer service in peri-urban areas adjacent to North Carolina municipalities. We performed the first quantitative, multi-county analysis of these disparities. Using publicly available data, we identified areas bordering municipalities and lacking community water and/or sewer service in 75 North Carolina counties. Logistic regression was performed to evaluate the relationship between race and access to service in peri-urban areas, controlling for population density, median home value, urban status, and percent white in the adjacent municipality. In the peri-urban areas analyzed, 67% of the population lacked community sewer service, and 33% lacked community water service. In areas other than those with no black residents, odds of having community water service (p<0.01) or at least one of the two services (p<0.05) were highest for census blocks with a small proportion of black residents and lowest in 100% black census blocks, though this trend did not hold for access to community sewer service alone. For example, odds of community water service were 85% higher in areas that were greater than 0% but less than 22% black than in 100% black areas (p<0.001). Peri-urban census blocks without black populations had the lowest odds of community water service, community sewer service, and at least one of the two services, but this difference was only statistically significant for sewer. Peri-urban areas lacking service with no black residents were wealthier than 100% black areas and areas with any percent black greater than 0%. Findings suggest two unserved groups of differing racial and socioeconomic status: (1) lower-income black populations potentially excluded from municipal services during the era of legal racial segregation and (2) higher-income non-black populations. Findings also suggest greater racial disparities in community water than community sewer services statewide.

Project description:BackgroundWater advisories, especially those concerning boiling drinking water, are widely used to reduce risks of infection from contaminants in the water supply. Since the effectiveness of boil water advisories (BWAs) depends on public compliance, monitoring the public response to such advisories is essential for protecting human health. However, assessments of public compliance with BWAs remain sparse. Thus, this study was aimed at investigating awareness and compliance among residents who had received BWAs in Baerum municipality in Norway.MethodWe conducted a cross-sectional study among 2764 residents who had received water advisories by SMS in the municipality of Baerum between January and September 2017. We analysed data from two focus group discussions and an online survey sent to all residents who had received an advisory. We conducted descriptive analyses and calculated odds ratios (OR) using logistic regression to identify associations of compliance and awareness with demographic characteristics.ResultsOf the 611 respondents, 67% reported that they had received a water advisory notification. Effective compliance rate with safe drinking water practices, either by storing clean drinking water or boiling tap water, after a water outage was 72% among those who remembered receiving a notification. Compliance with safe drinking water advisories was lower among men than women (OR 0.53, 95% CI 0.29-0.96), but was independent of age, education and household type. The main reason for respondents' non-compliance with safe water practices was that they perceived the water to be safe to drink after letting it flush through the tap until it became clear.ConclusionsAwareness of advisories was suboptimal among residents who had received notifications, but compliance was high. The present study highlights the need to improve the distribution, phrasing and content of water advisory notifications to achieve greater awareness and compliance. Future studies should include hard-to-reach groups with adequate data collection approaches and examine the use of BWAs in a national context to inform future policies on BWAs.

Project description:Urban areas usually display better health care services than rural areas, but data about suburban areas in China are lacking. Hence, this cross-sectional study compared the utilization of community basic medical services in Shanghai urban and suburban areas between 2009 and 2014. These data were used to improve the efficiency of community health service utilization and to provide a reference for solving the main health problems of the residents in urban and suburban areas of Shanghai. Using a two-stage random sampling method, questionnaires were completed by 73 community health service centers that were randomly selected from six districts that were also randomly selected from 17 counties in Shanghai. Descriptive statistics, principal component analysis, and forecast analysis were used to complete a gap analysis of basic health services utilization quality between urban and suburban areas. During the 6-year study period, there was an increasing trend toward greater efficiency of basic medical service provision, benefits of basic medical service provision, effectiveness of common chronic disease management, overall satisfaction of community residents, and two-way referral effects. In addition to the implementation effect of hypertension management and two-way referral, the remaining indicators showed a superior effect in urban areas compared with the suburbs (P<0.001). In addition, among the seven principal components, four principal component scores were better in urban areas than in suburban areas (P = <0.001, 0.004, 0.036, and 0.022). The urban comprehensive score also exceeded that of the suburbs (P<0.001). In summary, over the 6-year period, there was a rapidly increasing trend in basic medical service utilization. Comprehensive satisfaction clearly improved as well. Nevertheless, there was an imbalance in health service utilization between urban and suburban areas. There is a need for the health administrative department to address this imbalance between urban and suburban institutions and to provide the required support to underdeveloped areas to improve resident satisfaction.

Project description:ObjectivesThe objective of this study is to assess West Virginia pharmacists' stocking and dispensing practices of opioid-related medications and to identify the educational needs relating to providing naloxone in community pharmacies.DesignA cross-sectional, anonymous, 49-item survey was created and validated to assess the educational needs of West Virginia community pharmacists.SettingWest Virginia.ParticipantsThe data collection instrument was administered to 266 pharmacists currently licensed in West Virginia at 6 continuing pharmacy education events throughout the state from March 1 to June 15, 2016.Outcome measuresPharmacists' educational needs were determined using the Extended Parallel Process Model, which has 4 main constructs: perceived severity, perceived susceptibility, response efficacy, and self-efficacy. Pharmacists' stocking and dispensing of opioids and related medications were also assessed.ResultsPharmacists completed 157 surveys. They were mostly male (56.1%), full-time employees (67.5%), worked mostly in community pharmacies (69.4%), and had a mean age of 50.19 years (SD = 13.62). The newly adapted opioid perceived efficacy and perceived severity of opioid adverse events scales were tested for reliability and validity. Only 20.4% of the community pharmacists surveyed felt comfortable selling naloxone without a prescription. As for the other opioid-related medications, only 53.3% stocked buprenorphine and 74.8% stocked buprenorphine/naloxone.ConclusionsAs the most accessible health care providers, community pharmacists are acutely aware of how the opioid epidemic affects their communities. Some pharmacists in West Virginia are hesitant to stock and dispense opioids and opioid-dependence medications. Although this may decrease the flow of potentially abused drugs into the community, it may also restrict access to necessary therapy for patients with opioid use disorder. Furthermore, pharmacists in West Virginia are not yet comfortable stocking and dispensing naloxone. Tailored educational materials can help in controlling the pharmacists' fear and reinforce the benefits of over-the-counter naloxone use.

Project description:Abstract:Ten aerobic corrosive bacterial strains were isolated from a cooling tower water system (CWS) which were identified based on the biochemical characterization and 16S rRNA gene sequencing. Out of them, dominant corrosion-causing bacteria, namely, Bacillus thuringiensis EN2, Terribacillus aidingensis EN3, and Bacillus oleronius EN9, were selected for biocorrosion studies on mild steel 1010 (MS) in a CWS. The biocorrosion behaviour of EN2, EN3, and EN9 strains was studied using immersion test (weight loss method), electrochemical analysis, and surface analysis. To address the corrosion problems, an anti-corrosive study using a biocide, bronopol was also demonstrated. Scanning electron microscopy and Fourier-transform infrared spectroscopy analyses of the MS coupons with biofilm developed after exposure to CWS confirmed the accumulation of extracellular polymeric substances and revealed that biofilms was formed as microcolonies, which subsequently cause pitting corrosion. In contrast, the biocide system, no pitting type of corrosion, was observed and weight loss was reduced about 32 ± 2 mg over biotic system (286 ± 2 mg). FTIR results confirmed the adsorption of bronopol on the MS metal surface as protective layer (co-ordination of NH2-Fe3+) to prevent the biofilm formation and inhibit the corrosive chemical compounds and thus led to reduction of corrosion rate (10 ± 1 mm/year). Overall, the results from WL, EIS, SEM, XRD, and FTIR concluded that bronopol was identified as effective biocide and corrosion inhibitor which controls the both chemical and biocorrosion of MS in CWS.
