Exposure of California kindergartners to students with personal belief exemptions from mandated school entry vaccinations.

ABSTRACT: Personal belief exemptions (PBEs) from mandated school entry vaccinations have increased in California over the past decade. Infectious disease outbreaks in the state may be associated with the aggregation of intentionally unvaccinated children within schools. We sought to quantify the exposure of California kindergartners to children with PBEs at school.We used cross-sectional California Department of Public Health data on 3 kindergarten cohorts to define and calculate multiple measures of exposure to children with exemptions, including interaction and aggregation indices, for the state as a whole (2008-2010) and by county (2010).In 2010, the PBE rate in California was 2.3 per 100 students, and the school PBE rate for the average kindergartner with a PBE was 15.6 per 100. More than 7000 kindergartners in California attend schools with PBE rates greater than 20 per 100, including 2700 kindergartners with PBEs. Exposure measures vary considerably across counties.Our results suggest increasing levels of exposure among kindergarten students in California to other kindergartners with PBEs. Our data provide a concrete set of metrics through which public health and education officials can identify high-risk areas as targets for policy and programmatic interventions.

Project description:Importance:California implemented 3 interventions to increase uptake of vaccines. In 2014, Assembly bill 2109 tightened requirements for obtaining a personal belief exemption. A 2015 campaign provided educational materials to school staff on the proper application of conditional admission for kindergartners who were not up to date on required vaccinations. In 2016, Senate bill 277 eliminated personal belief exemptions. Prior research has not evaluated these 3 interventions together with regard to the vaccination status of students. Objective:To assess the changes in the yearly rates of kindergartners who were not up to date on required vaccinations who were entering school during the period of the interventions, by focusing on geographic clustering and the potential contacts of these kindergartners. Design, Setting, and Participants:Observational study that used cross-sectional school-entry data from 2000-2017 to calculate the rates of kindergartners attending California schools who were not up to date on required vaccinations. Exposures:Assembly bill 2109, a conditional admission education program, and Senate bill 277. Main Outcomes and Measures:The primary outcome was the yearly rate of kindergartners without up-to-date vaccination status. The secondary outcomes were (1) the modified aggregation index, which was used to assess the potential within-school contacts among kindergartners without up-to-date vaccination status, (2) the number of geographic clusters of schools with rates for kindergartners without up-to-date vaccination status that were higher than the rates for schools located outside the cluster, and (3) the number of schools located inside the geographic clusters. Results:In California between 2000 and 2017, 9 323 315 children started attending kindergarten and 721 593 were not up to date on required vaccinations. Prior to the interventions, the statewide rate of kindergartners without up-to-date status for required vaccinations increased from 7.80% during 2000 to 9.84% during 2013 and then decreased after the interventions to 4.87% during 2017. The percentage chance for within-school contact among kindergartners without up-to-date vaccination status decreased from 26.02% during 2014 to 4.56% (95% CI, 4.21%-4.99%) during 2017. During 2012-2013, there were 124 clusters that contained 3026 schools with high rates of kindergartners without up-to-date vaccination status. During 2014-2015, there were 93 clusters that contained 2290 schools with high rates of kindergartners without up-to-date vaccination status. During 2016-2017, there were 110 clusters that contained 1613 (95% CI, 1565-1691) schools. Conclusions and Relevance:In California, statewide legislative and educational interventions were associated with a decrease in the yearly rates of kindergartners without up-to-date vaccination status. These interventions also were associated with reductions in the number of schools inside the clusters with high rates of kindergartners without up-to-date vaccination status and the potential for contact among these kindergartners.

Project description:BACKGROUND:Psychological distress in medical students is a global issue and poses a risk to their health, academic performance, and ability to care for patients as clinicians. There has been limited research on psychological distress levels in students prior to starting medicine and no direct comparison between undergraduate and graduate-entry students. METHODS:Psychological distress was assessed using the 21-item Depression Anxiety and Stress Scale in 168 undergraduate-entry and 84 graduate-entry medical students at two separated campuses of the same university in the orientation week prior to starting classes. Mean scores and severity proportions were compared between the two cohorts of students. Demographic data was also collected and compared to distress scores using subgroup analysis. RESULTS:The response rate for the study was 60.9%. The majority of undergraduate and graduate-entry medical students were within the normal limits for depression (67.2% versus 70.2%, p = 0.63), anxiety (56.5% versus 44.0%, p = 0.06), and stress scores (74.4% versus 64.2%, p = 0.10). There was no significant difference between severity groups except for severe stress (2.3% versus 9.5%, p = 0.01). The mean scores of the clinically distressed groups indicated moderate levels of depression, moderate anxiety, and moderate stress scores. There were no significant differences between undergraduate or graduate-entry students for depressive ([Formula: see text] = 17.02 versus 15.76, p = 0.43), anxiety ([Formula: see text] = 14.22 versus 13.28, p = 0.39), and stress scores ([Formula: see text] = 20.83 versus 22.46, p = 0.24). Female gender and self-believed financial concerns were found be associated with higher levels stress in graduate entry students. CONCLUSIONS:The majority of medical students enter medical school with normal levels of psychological distress. However, a large number of undergraduate and graduate-entry medical students have significant levels of depressive, anxiety, and stress levels, without a significant difference between undergraduate or graduate-entry students. There are several limitation of this study but the results suggest that education and intervention may be required to support students from the earliest weeks of medical school.

Project description:Vaccine hesitancy continues to be an issue throughout the United States, as numerous vaccine hesitant parents are choosing to exempt their children from school-entry vaccination requirements for nonmedical reasons, despite the safety and effectiveness of vaccines. We conduct an analysis of how vaccine refusal, measured by the use of nonmedical exemptions (based on personal or religious beliefs) from vaccination (NMEs), evolved across space and over time in California.Using school-entry data from the California Department of Public Health, we examined NMEs for students entering kindergarten in California from 2000 to 2013. We conduct global and local spatial autocorrelation analysis to determine whether NME use became more geographically clustered over the study period and whether the location of local clusters of high use were temporally stable. We conducted a grouping analysis that identified the general temporal trends in NME use over the time period.The use of NMEs increased from 0.73% of all kindergarteners in 2000 to 3.09% in 2013 and became more geographically clustered over the study period. Local geographic clusters of high use were relatively isolated early in the study period, but expanded in size over time. The grouping analysis showed that regions with high NME use early in the study period were generally few (15% of all US Census tracts) and relatively isolated. Regions that had low initial NME use and moderate to large increases over the study period were located in close proximity to the initial high use regions. The grouping analysis also showed that roughly half of all tracts had 0% or very low NME use throughout the study period.We found an observable spatial structure to vaccine refusal and NME use over time, which appeared to be a self-reinforcing process, as well as a spatially diffusive process. Importantly, we found evidence that use of NMEs in the initially isolated regions appeared to stimulate vaccine refusal in geographically proximal regions. Thus, our results suggest that efforts aimed at decreasing future NME use may be most effective if they target regions where NME use is already high, as well as the nearby regions.
