This cohort study describes the differences in kidney cancer age-adjusted incidence and mortality rates between American Indians/Alaskan Natives (AI/ANs) and Whites in Oklahoma. Additionally, rates for the U.S. are updated to establish an epidemiological comparison between Oklahoma and the rest of the country. Materials and Methods. Kidney cancer age-adjusted incidence and mortality rates for Oklahoma were gathered using the Oklahoma Central Cancer Registry since 1999. National rates were obtained from the Center for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research database between 1997 and 2017. Rate ratios were used to compare incidence and mortality rates for AI/ANs and Whites within Oklahoma as well as the entire country. Joinpoint regression models were created to illustrate trends in kidney cancer incidence and mortality. Results. The age-adjusted incidence rate of kidney cancer in Oklahoma for AI/ANs and Whites was 32.3 and 15.8 per ...
Improved Geocoding of Cancer Registry Addresses in Urban and Rural Oklahoma

Addresses in rural counties were geocoded with poorer quality, preventing the instructive geographic research that informs policymaking. To improve the accuracy of the geocodes, we first utilized the United States Postal Service's LACSLink database to correct addresses; specifically, to convert old rural route-based addresses to modernized Enhanced 911 (E911) addresses. We created custom geocoders using regional E911 reference data sets and used existing national scope geocoders of NAVTEQ and the North American Association of Central Cancer Registries. We attempted to geocode 5,102 addresses, which are either regular street addresses or rural route addresses. In the process, we evaluated and tabulated performances of the address correction. Accordingly, we first tabulated how well each geocoder could geocode origi...

This research examines trends in lung cancer incidence rates by race and by gender within race during 2001-2010 in Oklahoma. Incident cases of lung cancer were obtained from the Oklahoma State Department of Health public use database. Cases were linked to the Indian Health Service database to reduce misclassification of American Indian race. Annual percent change (APC) was estimated by race and by gender within race to describe rates over time. Rates were considered to increase or decrease if the p-value for trend was < 0.05. Average lung cancer incidence rates were highest among American Indians (105.52 per 100,000) and lowest among whites (78.64 per 100,000). Lung cancer incidence rates declined among the overall white (APC: -2.17%; p = 0.001) and African American (APC: -2.95%; p = 0.003) populations, as well as white (APC: -3.02%; p < .001) and African American m...

Age-adjusted incidence rates obtained from the Oklahoma Central Cancer Registry are presented for all cancer sites combined and for the most common cancer sites among AI/ANs with comparisons to whites. Percentages of late stage cancers for breast, colorectal, and melanoma cancers are also presented. AI/ANs had a significantly higher overall cancer incidence rate compared to whites (629.8/100,000 vs. 503.3/100,000), with a rate ratio of 1.25 (95% CI: 1.22, 1.28). There was a significant disparity in the percentage of late stage melanoma cancers between 2005 and 2009, with 14.0% late stage melanoma for whites and 20.0% for AI/ANs (p-value:0.03). Overall, there were cancer disparities between AI/ANs and whites in Oklahoma. Incidence rates were higher among AI/ANs for all cancers and many site specific cancers.

Methods: Surveys were distributed to a list of registered voters age 65 and older in Oklahoma with a total of 1,248 surveys returned. Survey items asked about interests in services, classes and activities, plus current barriers to accessing and/or engaging in such programs. Findings: Survey respondents living in large rural towns (23.7%) and the urban core (21.5%) were significantly more likely than those in small rural towns (14.0%) or suburban areas (15.5%) to have attended a free health information event in the past year (P=0.0393). Older Oklahomans in small towns and isolated rural areas reported more frequently than those in the urban core that they would participate in congregate meals at a center (small town/isolated rural: 14.4%, urban core: 7.2%) (P=0.05). Lack of adequate facilities was more frequently reported by those residing in small town and isolated rural areas compared to urban core areas (16.4% vs. 7.8%, P=0.01). Finally, older Oklahomans in the large rural towns (0.6%) and small town and isolated rural locations (2.13%) less frequently reported use of senior information lines (Senior Infoline) than those in the urban core (6.0%) and in suburban areas (7.1%) (P=0.0009). Conclusions: Results of this survey provide useful data on senior interests and current barriers to community programs/activities have some unique trends among both urban and rural populations.

The purpose of this cross-sectional study was to determine associations between community PA environments and ECE classroom PA practices. We included licensed Oklahoma ECE directors serving 3-to-5-year-old children. Parks and playground locations were exported from Google Earth. National Walkability Index was derived from 2010 US Census data. ArcMap 10.6 was used to geocode ECE locations, which were within an Activity Desert if no parks/playgrounds were located within a 1-mile radius or if Walkability Index was 10.5 or below. Classroom PA practices were determined by using the Nutrition and PA Self-Assessment tool (NAP SACC). Barriers to implementing practices were reported. Most Head Starts (n = 41; 80.3%), center-based childcare settings (CBC; n = 135; 87.0%), and family childcare homes (FCCHs; n = 153; 96.4%) were in an Activity Desert. Parks/pl...

We conducted a cross-sectional survey with directors of Oklahoma-licensed ECE programs to assess policies and practices related to asthma control and to evaluate potential differences between Centers and Family Childcare Homes (FCCHs). Surveyed ECEs (n = 476) included Centers (56.7%), FCCHs (40.6%), and other program types (2.7%). Almost half (47.2%) of directors reported never receiving any asthma training. More Center directors were asthma-trained than FCCH directors (61.0% versus 42.0%, p < 0.0001). Most ECEs used asthma triggers, including bleach (88.5%) and air fresheners (73.6%). Centers were more likely to use bleach daily than were FCCHs (7...

Women are equally as likely as men to have bleeding disorders other than hemophilia and are disproportionately affected by these diseases due to the bleeding challenges of menstruation and childbirth. The most common bleeding disorder identified in women is von Willebrand disease (VWD). Heavy menstrual bleeding (HMB) is the most common symptom in women with VWD, occurring in up to 93% of patients. Among women with HMB, the reported prevalence of VWD ranges from 5─20%. Women with VWD are also more likely to be diagnosed with hemorrhagic ovarian cysts due to ovulation-associated bleeding and endometriosis due to increased retrograde menstruation. As a result, women with bleeding disorders are more likely to undergo hysterectomy and also undergo hysterectomy at an earlier age than women without bleeding disorders. In 2001, the American College of Obstetrics and Gynecology (ACOG) recommended VWD screening pri...

Marked disparities in the development of this cancer exist, with testicular cancer being more common in Caucasian men and men of higher socioeconomic status. The incidence of testicular cancer is increasing worldwide, and the reasons for this have not been well documented. It has been proposed that this increase may be due to highly prevalent environmental factors, or from exposure to polychlorinated biphenyls, polyvinyl chloride, cigarette smoking, and tetrahydrocannabinol (THC). For our analysis, data were obtained from the Oklahoma Central Cancer Registry and the Surveillance, Epidemiology and End Results program. Age-adjusted incidence rates and five-year relative survival were calculated for Oklahoma and for the US. Overall, incidence was lower in Oklahoma than the US, but no differences were observed between the US and Oklahoma regarding survival by year of diagnosis, race, age, and stage.

Diets higher in plant-based foods and lower in sodium, sugar, cholesterol, and saturated fat reduce cardiovascular disease risk. Objective The purpose of this study is to determine if greater home access to fruits, vegetables, and snacks is associated with cardiac dietary heath at home and Early Care and Education (ECE) centers in preschool-age children and also to determine if there is a difference in children's cardiac dietary health between home and ECE. Study Design, Settings, Participants This cross-sectional study involved children (3-5 years old, n = 88) and their primary caregivers from 15 licensed ECEs across Oklahoma. Parents reported home food access using the Healthy Home Survey and child's home dinner intake using the 3-Dinner Dietary Recall. Child ECE lunch consumption was recorded using the Dietary Observation for Child Care. The cardiac dietary score was composed of 6...

However, uptake of the HPV vaccine among American Indian and Alaska Native (AI/AN) adolescents has been low. AI/ANs also bear a disproportionate burden of cervical and other HPV-associated cancers. Increasing HPV vaccination rates is a national priority, but reviews and national surveys on HPV vaccination factors are lacking for the AI/AN population. The objective of this systematic review is to assess factors associated with HPV vaccination among AI/ANs in the USA.Methods and analysisA systematic review is proposed to synthesise the current literature on HPV vaccination factors in AI/ANs from 1 July 2006 until 30 September 2019. As applicable, controlled vocabulary terms, keywords and special features (eg, limits, explode and focus) will be incorporated into database searches. To maximise the identification of relevant studi...

The racial distribution of Oklahoma County closely mirrors that of the United States. Objective To evaluate VTE incidence and mortality, including demographic and racial subgroups. Design Population-based prospective study. Setting We conducted VTE surveillance at all relevant tertiary care facilities and outpatient clinics in Oklahoma County, Oklahoma during 2012 to 2014, using both active and passive methods. Active surveillance involved reviewing all imaging reports used to diagnose VTE. Passive surveillance entailed identifying VTE events from hospital discharge data and death certificate records. Measurements We used Poisson regression to calculate crude, age-stratified, and age-adjusted incidence and mortality rates per 1,000 population per year and 95% confidence intervals (CIs). Results The incidence rate of all VTE was 3.02 (2.92–3.12) for those age ≥18 yea...

Surveys were distributed to a list of registered voters aged 65 and older in Oklahoma with a total of 1,248 surveys returned (19.8%). Survey items asked about interests in services, classes, and activities, plus current barriers to accessing and/or engaging in such programs. To account for survey weighting, Rao-Scott Chi-Square Tests were performed to determine differences by demographic characteristics. We identified services, classes, and activities that were (and were not) of interest to seniors in Oklahoma with legal assistance (52.1%), exercise classes (46.6%), internet classes (40.7%), and indoor exercise activities (45.5%) receiving the highest level of interest. Barriers to interest in participating in programs included not wanting to go and not knowing availability of such services. The results of this survey provide useful data on health promotion gaps for seniors, interests and barriers to engaging in such activities, and guidance for statewide program development. Future program development needs to be focused on areas of interest for older adults, including legal assistance, exercise classes, and internet classes.

Active cancer contributes a 4-7 fold increased risk for VTE; however, the incidence of VTE stratified by subpopulations of patients diagnosed with cancer, especially race/ethnicity, is uncertain. Objective: Describe the incidence of VTE among adult patients (age ≥ 18 years) with a cancer diagnosis in Oklahoma County, OK according to age, gender, race, and cancer type. Methods: In collaboration with the Centers for Disease Control and Prevention, we established a population-based surveillance system for VTE in Oklahoma County, OK between April 1, 2012-March 31, 2014 to estimate the incidences of first-time and recurrent VTE events. The Commissioner of Health made VTE a reportable condition and delegated surveillance-related responsibilities to the University of Oklahoma, College of Public Health. Active surveillance involved reviewing imaging studies (e.g., chest computed tomography and compressio...

However, most of these databases are de-identified which limits their utility for estimating VTE incidence due to the inability to identify multiple hospitalizations for the same VTE event, and the inability to differentiate between first-time and recurrent VTE events. Objective We aimed to estimate the magnitude of error in estimates of VTE incidence derived from hospital discharge data by comparing the results obtained when patient identifying information is included, thus enabling us to remove duplicate patient events and stratify by first-time and recurrent VTE events, to the estimates obtained using only de-identified data. Methods In collaboration with the Centers for Disease Control and Prevention (CDC) and the Oklahoma State Department of Health (OSDH), we established a pilot surveillance system for VTE events in Oklahoma County, OK during 2012–2014.

However, uptake of the HPV vaccine among American Indian and Alaska Native (AI/AN) adolescents has been low. AI/ANs also bear a disproportionate burden of cervical and other HPV-associated cancers. Increasing HPV vaccination rates is a national priority, but reviews and national surveys on HPV vaccination factors are lacking for the AI/AN population. The objective of this systematic review is to assess factors associated with HPV vaccination among AI/ANs in the USA.Methods and analysisA systematic review is proposed to synthesise the current literature on HPV vaccination factors in AI/ANs from 1 July 2006 until 30 September 2019. As applicable, controlled vocabulary terms, keywords and special features (eg, limits, explode and focus) will be incorporated into database searches. To maximise the identification of relevant studi...

The racial distribution of Oklahoma County closely mirrors that of the United States. Objective To evaluate VTE incidence and mortality, including demographic and racial subgroups. Design Population-based prospective study. Setting We conducted VTE surveillance at all relevant tertiary care facilities and outpatient clinics in Oklahoma County, Oklahoma during 2012 to 2014, using both active and passive methods. Active surveillance involved reviewing all imaging reports used to diagnose VTE. Passive surveillance entailed identifying VTE events from hospital discharge data and death certificate records. Measurements We used Poisson regression to calculate crude, age-stratified, and age-adjusted incidence and mortality rates per 1,000 population per year and 95% confidence intervals (CIs). Results The incidence rate of all VTE was 3.02 (2.92–3.12) for those age ≥18 yea...
Assessing Statewide Need for Older Adult Health Promotion Services: The Oklahoma Experience
Journal of Social Service Research

Surveys were distributed to a list of registered voters aged 65 and older in Oklahoma with a total of 1,248 surveys returned (19.8%). Survey items asked about interests in services, classes, and activities, plus current barriers to accessing and/or engaging in such programs. To account for survey weighting, Rao-Scott Chi-Square Tests were performed to determine differences by demographic characteristics. We identified services, classes, and activities that were (and were not) of interest to seniors in Oklahoma with legal assistance (52.1%), exercise classes (46.6%), internet classes (40.7%), and indoor exercise activities (45.5%) receiving the highest level of interest. Barriers to interest in participating in programs included not wanting to go and not knowing availability of such services. The results of this survey provide useful data on health promotion gaps for seniors, interests and barriers to engaging in such activities, and guidance for statewide program development. Future program development needs to be focused on areas of interest for older adults, including legal assistance, exercise classes, and internet classes.
Incidence of VTE Among Patients with a Cancer Diagnosis in Oklahoma County

Active cancer contributes a 4-7 fold increased risk for VTE; however, the incidence of VTE stratified by subpopulations of patients diagnosed with cancer, especially race/ethnicity, is uncertain. Objective: Describe the incidence of VTE among adult patients (age ≥ 18 years) with a cancer diagnosis in Oklahoma County, OK according to age, gender, race, and cancer type. Methods: In collaboration with the Centers for Disease Control and Prevention, we established a population-based surveillance system for VTE in Oklahoma County, OK between April 1, 2012-March 31, 2014 to estimate the incidences of first-time and recurrent VTE events. The Commissioner of Health made VTE a reportable condition and delegated surveillance-related responsibilities to the University of Oklahoma, College of Public Health. Active surveillance involved reviewing imaging studies (e.g., chest computed tomography and compressio...
Incidence of Venous Thromboembolism Estimated Using Hospital Discharge Data: Differences Between Event-Based Estimates and Patient-Based Estimates

However, most of these databases are de-identified which limits their utility for estimating VTE incidence due to the inability to identify multiple hospitalizations for the same VTE event, and the inability to differentiate between first-time and recurrent VTE events. Objective We aimed to estimate the magnitude of error in estimates of VTE incidence derived from hospital discharge data by comparing the results obtained when patient identifying information is included, thus enabling us to remove duplicate patient events and stratify by first-time and recurrent VTE events, to the estimates obtained using only de-identified data. Methods In collaboration with the Centers for Disease Control and Prevention (CDC) and the Oklahoma State Department of Health (OSDH), we established a pilot surveillance system for VTE events in Oklahoma County, OK during 2012–2014.
