Helicobacter pylori treatment knowledge, access and barriers: A cross-sectional study.

BACKGROUND: Helicobacter pylori (Hp) is among the most common bacterial infections in the world and one of the most common infectious agents linked to malignancy, gastric cancer (GC). Within the US there is high disparity in the rates of Hp infection and associated diseases. Hp infection is treatable, and knowledge may influence screening and treatment seeking behaviors. MATERIALS AND METHODS: In this cross-sectional study of 1042 respondents recruited from the Online Amazon MTurk platform, we sought to assess baseline knowledge of Hp and to gain insight into barriers related to Hp care. RESULTS: Just over half (52.3%) reported some prior knowledge of Hp with 11.7% (n = 122) reporting being treated for Hp themselves and 21.4% reporting family members diagnosed with Hp. Of respondents reporting prior treatment, 95 (78%) reported GI upset and 27 (21%) reported not completing medications. Specific to Hp and GC, 70% indicated that a belief that the treatment was worse than the symptoms would affect their willingness to seek care, while 81% indicated knowing Hp can cause GC would affect their treatment decisions and knowing their gastric symptoms were caused by Hp would affect their willingness to receive care. CONCLUSIONS: Knowledge of Hp in this US sample of online respondents is low and self-reported difficulties with treatment compliance is high. Increasing awareness of this infection and addressing the challenges to treatment compliance could potentially reduce rates of Hp antibiotic resistance and progression to GC or other complications of Hp infection.

Chronic kidney disease unawareness and determinants using 1999-2014 National Health and Nutrition Examination Survey Data.

BACKGROUND: Although chronic kidney disease (CKD) affects 15% of the United States (US) population, <10% of the US CKD population is aware of their disease. This is significant as untreated CKD can progress to end-stage renal disease which would require dialysis or transplantation. This study aimed to provide updated information regarding US CKD unawareness. METHODS: Data from the 1999-2014 National Health and Nutrition Examination Survey (NHANES) were used (n = 38 474); response rate > 70%. CKD self-report and lab-confirmed CKD were used to assess CKD unawareness. Adjusted logistic regression models examined association between unawareness and patient characteristics. RESULTS: In individuals with lab-confirmed CKD (n = 7137, 14.3%), 91.5% answered 'no' to self-report question; in those without CKD, 1.1% answered 'yes' to self-report question. In those with lab-confirmed CKD, in the adjusted models, increased age [odds ratio (ORs), 1.03 (95%CI, 1.02-1.04)] and female sex [OR, 1.37 (95%CI, 1.08-1.72)] were statistically significantly associated with greater odds of being unaware of CKD. CONCLUSION: These findings demonstrated high unawareness of disease status as there was a discrepancy between respondents' self-reported CKD diagnosis and lab-confirmed CKD. Older individuals and women may be more unaware of their CKD; these groups should be queried about reasons for increased unawareness.

"Nobody Is Talking About It": Diné (Navajo) Communities Speak About Stomach Cancer and Helicobacter pylori Infections.

Stomach cancer is the third leading cause of cancer death globally. Helicobacter pylori plays a role in the healthy human gut, but is also associated with multiple chronic diseases, including stomach cancer. Though H. pylori prevalence is declining in parts of the world, it remains high among certain populations. In Arizona, stomach cancer rates are 3-4 times higher among the Navajo Nation population as compared with the non-Hispanic white population. This pilot project assessed adult Diné (Navajo) individuals' understanding and awareness regarding H. pylori infection and stomach cancer. Focus groups were held in three Diné communities. Data were analyzed thematically using a multi-investigator consensus approach. Participants had limited knowledge of H. pylori infection and stomach cancer and perceived local medical providers as also having limited knowledge on these conditions. Participants described poor health care experiences, structural inequalities, and environmental concerns and associated these with H. pylori infection and stomach cancer. This study highlights the need for additional research and education on current knowledge and perceptions of stomach cancer and H. pylori infections in Navajo Nation.

Factors Associated with Cancer Screening Among Hopi Men.

Cancer screening rates remain low among American Indian men, and cancer screening behaviors and barriers to cancer screening among American Indian men are not well understood. This study evaluated cancer screening behaviors in 102 Hopi men who were 50 years of age or older from the Hopi Survey of Cancer and Chronic Disease. Reported cancer screening frequencies were 15.7%, 45.1%, and 35.3% for fecal occult blood test (FOBT), colonoscopy, and prostate-specific antigen (PSA) test, respectively. Among men who reported having had a FOBT, 81.2% had the test more than 1 year ago. Among men who reported a colonoscopy, 60.8% had colonoscopy within the past 3 years. Similarly, among men who reported having had PSA, 72.3% had PSA within the past 3 years. "No one told me" was the most common answer for not undergoing FOBT (33.7%), colonoscopy (48.2%), and PSA (39.4%). Men who reported having had a PSA or digital rectal exam were three times as likely to also report having a FOBT or colonoscopy (odds ratio [OR] 3.19, 95% confidence interval [CI]: 1.21-8.46). Younger age (< 65) was associated with reduced odds of ever having prostate cancer screening (OR 0.28, 95% CI: 0.10-0.77). Ever having colorectal cancer screening and previous diagnosis of cancer increased odds of ever having prostate cancer screening (OR 3.15, 95% CI: 1.13-8.81 and OR 5.28, 95% CI: 1.15-24.18 respectively). This study illustrates the importance of community cancer education for men to improve cancer screening participation.

Community transmission of multidrug-resistant tuberculosis is associated with activity space overlap in Lima, Peru.

BACKGROUND: Transmission of multidrug-resistant tuberculosis (MDRTB) requires spatial proximity between infectious cases and susceptible persons. We assess activity space overlap among MDRTB cases and community controls to identify potential areas of transmission. METHODS: We enrolled 35 MDRTB cases and 64 TB-free community controls in Lima, Peru. Cases were whole genome sequenced and strain clustering was used as a proxy for transmission. GPS data were gathered from participants over seven days. Kernel density estimation methods were used to construct activity spaces from GPS locations and the utilization distribution overlap index (UDOI) was used to quantify activity space overlap. RESULTS: Activity spaces of controls (median = 35.6 km2, IQR = 25.1-54) were larger than cases (median = 21.3 km2, IQR = 17.9-48.6) (P = 0.02). Activity space overlap was greatest among genetically clustered cases (mean UDOI = 0.63, sd = 0.67) and lowest between cases and controls (mean UDOI = 0.13, sd = 0.28). UDOI was positively associated with genetic similarity of MDRTB strains between case pairs (P < 0.001). The odds of two cases being genetically clustered increased by 22% per 0.10 increase in UDOI (OR = 1.22, CI = 1.09-1.36, P < 0.001). CONCLUSIONS: Activity space overlap is associated with MDRTB clustering. MDRTB transmission may be occurring in small, overlapping activity spaces in community settings. GPS studies may be useful in identifying new areas of MDRTB transmission.

Household and behavioral determinants of indoor PM2.5 in a rural solid fuel burning Native American community.

Indoor and outdoor concentrations of PM2.5 were measured for 24 h during heating and non-heating seasons in a rural solid fuel burning Native American community. Household building characteristics were collected during the initial home sampling visit using technician walkthrough questionnaires, and behavioral factors were collected through questionnaires by interviewers. To identify seasonal behavioral factors and household characteristics associated with indoor PM2.5 , data were analyzed separately by heating and non-heating seasons using multivariable regression. Concentrations of PM2.5 were significantly higher during the heating season (indoor: 36.2 µg/m3 ; outdoor: 22.1 µg/m3 ) compared with the non-heating season (indoor: 14.6 µg/m3 ; outdoor: 9.3 µg/m3 ). Heating season indoor PM2.5 was strongly associated with heating fuel type, housing type, indoor pests, use of a climate control unit, number of interior doors, and indoor relative humidity. During the non-heating season, different behavioral and household characteristics were associated with indoor PM2.5 concentrations (indoor smoking and/or burning incense, opening doors and windows, area of surrounding environment, building size and height, and outdoor PM2.5 ). Homes heated with coal and/or wood, or a combination of coal and/or wood with electricity and/or natural gas had elevated indoor PM2.5 concentrations that exceeded both the EPA ambient standard (35 µg/m3 ) and the WHO guideline (25 µg/m3 ).

Use of cervical cancer preventive services among US women aged 21-29: an assessment of the 2010 Affordable Care Act rollout through 2018.

PURPOSE: The 2010 Affordable Care Act (ACA) provided millions of people with health insurance coverage and facilitated routine cancer screening by requiring insurers to cover preventive services without cost-sharing. Despite greater access to affordable cancer screening, Pap testing has declined over time. The aim of this study is to assess participation in Pap test and HPV vaccination, and adherence to guidelines as outlined by the American Cancer Society (ACS) from the 2010 ACA provision eliminating cost-sharing for preventive services. METHODS: Using multi-year responses from the Behavioral Risk Factor Surveillance System, we examined the association between the ACA and participation in and adherence to Pap testing and HPV vaccination behaviors as set by the ACS. The sample included women aged 21-29 who completed the survey between 2008 and 2018 (every other year) and who live in 24 US States (N = 37,893). RESULTS: Results showed significant decreases in Pap testing rates but increases in the uptake of the HPV vaccine series for all age groups and across all demographics. Post-ACA year significantly predicted increases in HPV + Pap co-testing participation and adherence. Women with health insurance coverage were more likely to engage in both behaviors. CONCLUSION: Findings raise concerns around declines in the proportion of women receiving and adhering to Pap testing guidelines. A need exists for research to examine the role of increases in HPV vaccination uptake on decreases in Pap testing. Moreover, effective strategies should target increases in cervical cancer screening uptake among women vaccinated against HPV.

Effects of HIV status on non-metastatic cervical cancer progression among patients in Lusaka, Zambia.

INTRODUCTION: Sub-Saharan Africa has the highest global incidence of cervical cancer. Cervical cancer is the most common cause of cancer morbidity and mortality among women in Zambia. HIV increases the risk for cervical cancer and with a national Zambian adult HIV prevalence of 16%, it is important to investigate the impact of HIV on the progression of cervical cancer. We measured differences in cervical cancer progression between HIV-positive and HIV-negative patients in Zambia. METHODS: This study included 577 stage I and II cervical cancer patients seen between January 2008 and December 2012 at the Cancer Diseases Hospital in Lusaka, Zambia. The inclusion criteria for records during the study period included known HIV status and FIGO stage I and II cervical cancer at initial date of registration in the Cancer Diseases Hospital. Medical records were abstracted for clinical and epidemiological data. Cancer databases were linked to the national HIV database to assess HIV status among cervical cancer patients. Logistic regression examined the association between HIV and progression, which was defined as metastatic or residual tumor after 3 months of initial treatment. RESULTS: A total of 2451 cervical cancer cases were identified, and after exclusion criteria were performed the final analysis population totaled 537 patients with stage I and II cervical cancer with known HIV status (224 HIV-positive and 313 HIV-negative). HIV-positive women were, on average, 10 years younger than HIV-negative women who had a median age of 42, ranging between 25 and 72. A total of 416 (77.5%) patients received external beam radiation, and only 249 (46.4%) patients received the recommended treatment of chemotherapy, external beam radiation, and brachytherapy. Most patients were stage II (85.7%) and had squamous cell carcinoma (74.7%). HIV-positive patients were more likely to receive lower doses of external beam radiation than HIV-negative patients (47% vs 37%; P<0.05, respectively). The median total dose of external beam radiation for HIV-positive and HIV-negative patients was 46 Gy and 50 Gy, respectively. HIV positivity did not lead to tumor progression (25.4% in HIV-positive vs 23.9% in HIV-negative, OR 1.04, 95% CI [0.57, 1.92]). However, among a subset of HIV-positive patients, longer duration of infection was associated with lower odds of progression. CONCLUSION: There was no significant impact on non-metastatic cervical cancer progression by HIV status among patients in Lusaka, Zambia. The high prevalence of HIV among cervical cancer patients suggest that HIV-positive patients should be a primary target group for HPV vaccinations, screening, and early detection.

A Case-Control Study to Identify Community Venues Associated with Genetically-clustered, Multidrug-resistant Tuberculosis Disease in Lima, Peru.

BACKGROUND: The majority of tuberculosis transmission occurs in community settings. Our primary aim in this study was to assess the association between exposure to community venues and multidrug-resistant (MDR) tuberculosis. Our secondary aim was to describe the social networks of MDR tuberculosis cases and controls. METHODS: We recruited laboratory-confirmed MDR tuberculosis cases and community controls that were matched on age and sex. Whole-genome sequencing was used to identify genetically clustered cases. Venue tracing interviews (nonblinded) were conducted to enumerate community venues frequented by participants. Logistic regression was used to assess the association between MDR tuberculosis and person-time spent in community venues. A location-based social network was constructed, with respondents connected if they reported frequenting the same venue, and an exponential random graph model (ERGM) was fitted to model the network. RESULTS: We enrolled 59 cases and 65 controls. Participants reported 729 unique venues. The mean number of venues reported was similar in both groups (P = .92). Person-time in healthcare venues (adjusted odds ratio [aOR] = 1.67, P = .01), schools (aOR = 1.53, P < .01), and transportation venues (aOR = 1.25, P = .03) was associated with MDR tuberculosis. Healthcare venues, markets, cinemas, and transportation venues were commonly shared among clustered cases. The ERGM indicated significant community segregation between cases and controls. Case networks were more densely connected. CONCLUSIONS: Exposure to healthcare venues, schools, and transportation venues was associated with MDR tuberculosis. Intervention across the segregated network of case venues may be necessary to effectively stem transmission.

Economic impact of epilepsy and the cost of nonadherence to antiepileptic drugs in older Medicare beneficiaries.

Epilepsy is most prevalent among older individuals, and its economic impact is substantial. The development of economic burden estimates that account for known confounders, and using percent incremental costs may provide meaningful comparison across time and different health systems. The first objective of the current study was to estimate the percent incremental healthcare costs and the odds ratio (OR) for inpatient utilization for older Medicare beneficiaries with epilepsy and without epilepsy. The second objective was to estimate the percent incremental healthcare costs and the OR for inpatient utilization associated with antiepileptic drug (AED) nonadherence among Medicare beneficiaries with epilepsy. The OR of inpatient utilization for cases compared with controls (i.e., non-cases) were 2.4 (95% CI 2.3 to 2.6, p-value<0.0001) for prevalent epilepsy and 3.6 (95% CI 3.2 to 4.0, p-value<0.0001) for incident epilepsy. With respect to total health care costs, prevalent cases incurred 61.8% (95% CI 56.6 to 67.1%, p-value<0.0001) higher costs than controls while incident cases incurred 71.2% (95% CI 63.2 to 79.5%, p-value <0.0001) higher costs than controls. The nonadherence rates were 33.6 and 32.9% for prevalent and incident cases, respectively. Compared to nonadherent cases, the OR of inpatient utilization for adherent prevalent cases was 0.66 (95% CI 0.55 to 0.81, p-value <0.0001). The cost saving for a prevalent case adherent to AEDs was 13.2% (95% CI 6.6 to 19.4%, p-value=0.0001) compared to a nonadherent case. An incident case adherent to AEDs spent 16.4% (95% CI 6.5 to 25.2%, p-value=0.002) less than a nonadherent incident case on health care. Epilepsy is associated with higher health care costs and utilization. Older Medicare beneficiaries with epilepsy incur higher total health care spending and have higher inpatient utilization than those without epilepsy. Total health care spending is less for older Medicare beneficiaries who have prevalent or incident epilepsy if they are adherent to AEDs.

Greater Adherence to Cancer Prevention Guidelines Is Associated with Higher Circulating Concentrations of Vitamin D Metabolites in a Cross-Sectional Analysis of Pooled Participants from 2 Chemoprevention Trials.

Background: Several lifestyle factors targeted by the American Cancer Society (ACS) Nutrition and Physical Activity Cancer Prevention Guidelines are also associated with circulating concentrations of vitamin D metabolites. This suggests that greater adherence to the ACS guidelines may be related to better vitamin D status.Objective: We examined the relation between adherence to the ACS guidelines and circulating concentrations of 2 vitamin D metabolites, 25-hydroxycholecalciferol [25(OH)D] and 1α,25-dihydroxyvitamin D [1,25(OH)2D].Methods: We conducted cross-sectional analyses of pooled participants from the Wheat Bran Fiber (n = 503) and Ursodeoxycholic Acid (n = 854) trials. A cumulative adherence score was constructed with the use of baseline data on body size, diet, physical activity, and alcohol consumption. Continuous vitamin D metabolite concentrations and clinically relevant categories were evaluated with the use of multiple linear and logistic regression models, respectively.Results: The most adherent participants were more likely to be older, white, and nonsmokers than were the least adherent. A statistically significant association was observed between guideline adherence and concentrations of circulating 25(OH)D (means ± SEs-high adherence: 32.0 ± 0.8 ng/mL; low adherence: 26.4 ± 0.7 ng/mL; P-trend < 0.001). For 1,25(OH)2D concentrations, high adherence was again significantly related to greater metabolite concentrations, with mean ± SE concentrations of 36.3 ± 1.3 pg/mL and 31.9 ± 1.0 pg/mL for high- and low-adherers, respectively (P-trend = 0.008). Furthermore, the odds of attaining a sufficient 25(OH)D status were 4.37 times higher for those most adherent than for those least adherent (95% CI: 2.47, 7.71 times).Conclusion: These findings demonstrate that greater adherence to the ACS guidelines is associated with higher circulating concentrations of both of 25(OH)D and 1,25(OH)2D.

Management of Helicobacter Pylori in the United States: Results from a national survey of gastroenterology physicians.

BACKGROUND AND AIMS: We sought to determine current knowledge and practices among gastroenterology physicians and assess adherence to current guidelines for H. pylori management. METHODS: Online surveys were distributed in 2014 to practicing gastroenterology physicians for information related to the diagnosis and treatment of H. pylori infection. RESULTS: A total of 582 completed surveys were reviewed. The H. pylori screening test used "almost always" was gastric biopsy obtained during endoscopy (histology) (59%) followed by stool antigen test (20%). Standard triple therapy for 14days was commonly prescribed by 53% of respondents. The stool antigen test was most frequently chosen to confirm H. pylori eradication (51%), although only 58% of physicians checked for eradication in patients who underwent treatment. CONCLUSIONS: Adherence to current American College of Gastroenterology guidelines is low. Although more physicians treat patients with a positive H. pylori test, only half ensure eradication after treatment. Improving knowledge of the resistance patterns of H. pylori may be critical to ensure successful eradication.

Self-reported depression and perceived financial burden among long-term rectal cancer survivors.

OBJECTIVES: Types of surgery for rectal cancer (RC), including permanent ostomy (PO) or temporary ostomy followed by anastomosis (TO) or initial anastomosis (AN), can affect psychological and financial well-being during active treatment. However, these relationships have not been well studied among long-term survivors (≥5 years post-diagnosis). METHODS: A mailed survey with 576 long-term RC survivors who were members of Kaiser Permanente was conducted in 2010-2011. Prevalence of current depression was ascertained using a score of ≤45.6 on the Short Form-12 version 2 mental component summary. Perceived financial burden was assessed using a Likert scale ranging from 0 (none) to 10 (severe). Regression analyses were used to measure associations after adjustment for covariates. RESULTS: The overall prevalence of depression was 24% among RC survivors with the highest prevalence among those with a history of PO (31%). The adjusted odds of depression among TO and AN survivors were lower than that among PO survivors, 0.42 (CI95% 0.20-0.89) and 0.59 (CI95% 0.37-0.93), respectively. Twenty-two percent perceived moderate-to-high current financial burden (≥4 points). PO survivors also reported higher mean financial burden than AN survivors (2.6 vs. 1.6, respectively; p = 0.002), but perceived burden comparably to TO survivors (2.3). Self-reported depression was associated with higher perceived financial burden (p < 0.001); surgical procedure history did not modify this relationship. CONCLUSIONS: Depression was reported frequently among these long-term RC survivors, particularly among PO survivors. Depression was associated with greater perception of financial burden. Screening for depression and assessing financial well-being might improve care among long-term RC survivors.Copyright © 2015 John Wiley & Sons, Ltd.

An Open-Label Randomized Crossover Trial of Lyophilized Black Raspberries on Postprandial Inflammation in Older Overweight Males: A Pilot Study.

This study was a 14-day, outpatient, open-label randomized crossover trial of lyophilized black raspberries (BRBs) in older overweight or obese males to determine whether BRB consumption affects postprandial inflammation associated with consumption of a high-fat high-calorie (HFHC) meal. Ten study participants consumed 45 g/d of lyophilized BRBs for 4 days, followed by a HFHC breakfast plus BRBs on day 6 or consumed the HFHC breakfast on day 6 without previous consumption of BRBs and then crossed over to the other treatment after a 2-day washout period. Blood samples were obtained before and 1, 2, 4, 8, and 12 hours after consumption of the HFHC breakfast. The primary study outcomes were changes in area under the concentration-time curve (AUC) for interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-α). The secondary outcomes were safety and tolerability of lyophilized BRB powder. The chronology and values of measured serum concentrations for IL-6, TNF-α, and CRP were consistent with those described previously by other investigators. The AUC of serum IL-6 was lowered significantly (P = 0.03, n = 10) with BRB consumption (34.3 ± 7.6 pg·mL⁻¹·h⁻¹ compared with 42.4 ± 17.9 pg·mL⁻¹·h⁻¹ for consumption of the HFHC meal alone). However, no significant differences (change in AUC) were calculated for serum CRP and TNF-α. The findings of this pilot study suggest that consumption of lyophilized BRBs may attenuate postprandial inflammation in overweight or obese males consuming a HFHC meal. Further investigation of BRBs is warranted to better elucidate their inflammomodulatory potential.

Fire fit: assessing comprehensive fitness and injury risk in the fire service.

PURPOSE: This study sought to develop a comprehensive measure of fitness that is predictive of injury risk and can be used in the fire service to assess individual-level health and fit-for-duty status. METHODS: A retrospective occupational cohort of 799 career fire service employees was observed over the years 2005-2009. An equally weighted score for comprehensive fitness was calculated based on cardiovascular fitness, muscular strength, endurance, flexibility, and body composition. Repeated measures survival analyses were used to estimate the risk of any injury, sprain or strain, and exercise-related injuries in relation to comprehensive fitness. RESULTS: A well-distributed comprehensive fitness score was developed to distinguish three tiers of overall fitness status. Intraclass correlations identified flexibility, total grip strength, percent body fat, and resting heart rate as the most reliable fitness metrics, while push-ups, sit-ups, and aerobic capacity demonstrated poor reliability. In general, individuals with a lower comprehensive fitness status had an increased injury risk of injury as compared to the most fit individuals. The risk of any injury was 1.82 (95% CI 1.06-3.11) times as likely for the least fit individuals, as compared to individuals in the top fire fitness category, increasing to 2.90 (95% CI 1.48-5.66) when restricted to sprains and strains. CONCLUSIONS: This 5-year analysis of clinical occupational health assessments enabled the development of a relevant metric for relating comprehensive fitness with the risk of injury. Results were consistent with previous studies focused on cardiorespiratory fitness, but also less susceptible to inter-individual variability of discrete measurements.

Evaluation of Project Students are Sun Safe (SASS): A University Student-Delivered Skin Cancer Prevention Program for Schools.

Skin cancer is the most common cancer in the USA and is increasing in children and young adults. Adolescents are an important target population for sun-safety interventions with ultraviolet radiation as the strongest risk factor for developing skin cancer. Schools are an ideal setting to intervene with adolescents. A novel Arizona skin cancer prevention in-class education-activity program, Project 'Students are Sun Safe' (SASS), was designed to be delivered by university students for middle school and high school students. Participant students completed the pre- and post-program tests and a satisfaction questionnaire; teachers completed reviews. The evaluation examined the program's influence on participants' sun-safety knowledge, perceptions, and behaviors; satisfaction with the program; and intent to change. After exposure to Project SASS, participants were more likely to perceive a high risk of skin cancer, report negative attitudes toward tanned skin, and answer knowledge-based questions correctly. There were minimal differences in self-reported sun-safety behaviors, though participants did report intent to change. Both participants and teachers were satisfied with the program. Project SASS appears to be an effective sun-safety program for middle school and high school students for knowledge and perceptions, and the results confirm that appropriately tailoring program components to the target population has strong potential to impact adolescent perceived susceptibility, knowledge, and behavioral intent. The strengths and weaknesses of Project SASS have many implications for public health practice, and Project SASS may hold promise to be a model for skin cancer prevention in adolescents.

The association of aerobic fitness with injuries in the fire service.

The aim of the present study was to understand the risk of injury in relation to fitness in a retrospective occupational cohort of firefighters in Tucson, Arizona, from 2005 to 2009. Annual medical evaluations and injury surveillance data were linked to compare levels of aerobic fitness in injured employees with those in noninjured employees. The individual outcomes evaluated included all injuries, exercise-related injuries, and sprains and strains. Time-to-event analyses were conducted to determine the association between levels of fitness and injury likelihood. Fitness, defined by relative aerobic capacity (Vo2max), was associated with injury risk. Persons in the lowest fitness level category (Vo2max <43 mL/kg/minute) were 2.2 times more likely (95% confidence interval: 1.72, 2.88) to sustain injury than were those in the highest fitness level category (Vo2max >48 mL/kg/minute). Those with a Vo2max between 43 and 48 mL/kg/minute were 1.38 times (95% confidence interval: 1.06, 1.78) more likely to incur injury. Hazard ratios were found to be greater for sprains and strains. Our results suggest that improving relative aerobic capacity by 1 metabolic equivalent of task (approximately 3.5 mL/kg/minute) reduces the risk of any injury by 14%. These findings illustrate the importance of fitness in reducing the risk of injury in physically demanding occupations, such as the fire service, and support the need to provide dedicated resources for structured fitness programming and the promotion of injury prevention strategies to people in those fields.

Sedentary behavior is associated with colorectal adenoma recurrence in men.

PURPOSE: The association between physical activity and colorectal adenoma is equivocal. This study was designed to assess the relationship between physical activity and colorectal adenoma recurrence. METHODS: Pooled analyses from two randomized, controlled trials included 1,730 participants who completed the Arizona Activity Frequency Questionnaire at baseline, had a colorectal adenoma removed within 6 months of study registration, and had a follow-up colonoscopy during the trial. Logistic regression modeling was employed to estimate the effect of sedentary behavior, light-intensity physical activity, and moderate-vigorous physical activity on colorectal adenoma recurrence. RESULTS: No statistically significant trends were found for any activity type and odds of colorectal adenoma recurrence in the pooled population. However, males with the highest levels of sedentary time experienced 47% higher odds of adenoma recurrence. Compared to the lowest quartile of sedentary time, the ORs (95% CIs) for the second, third, and fourth quartiles among men were 1.23 (0.88, 1.74), 1.41 (0.99, 2.01), and 1.47 (1.03, 2.11), respectively (p(trend) = 0.03). No similar association was observed for women. CONCLUSIONS: This study suggests that sedentary behavior is associated with a higher risk of colorectal adenoma recurrence among men, providing evidence of detrimental effects of a sedentary lifestyle early in the carcinogenesis pathway.

Mammography Compliance for Arizona and New Mexico Hispanic and American Indian Women 2016-2018.

Hispanic and American Indian (AI) women experience lower breast cancer incidence than non-Hispanic White (NHW) women, but later-stage diagnoses and lower survival rates, suggesting issues with screening and healthcare access. Between 1999-2015, NHW breast cancer incidence decreased by 10% but increased by 8% for AI women. This study used 2016 and 2018 Behavioral Risk Factor Surveillance System data for Arizona and New Mexico to explore mammography screening. Analyses included Hispanic, AI, and NHW women aged ≥40 years (n = 12,830) to calculate age-specific compliance by race/ethnicity, logistic regression, and adjusted and sample-weighted evaluated associations between compliance and socio-economic covariates. In total, 75.1% of Hispanic women aged 50-74 reported mammography in the past two years (United States Preventive Services Task Force compliant) compared to 73.9% of NHW and 71.0% of AI women. Women who reported doctor visits in the past 12 months were likelier to comply than those without (AOR = 4.2 for Hispanic, 2.9 for AI, and 3.2 for NHW women). Reporting access to a personal doctor was related to compliance, except for AI women. While screening compliance was over 74%, visiting a healthcare provider in the past 12 months was essential. AI women reported issues that suggest unique challenges when deciding on mammography.

Associations of Prenatal Agricultural Farm Work with Fetal Overgrowth and Pregnancy Complications in State of Arizona Birth Records.

OBJECTIVE: The purpose of this study is to examine fetal growth outcomes from agricultural worker households. METHODS: Using Arizona 2006 to 2013 birth certificates with parental occupation, we identified N = 623,185 live births by agricultural household status. Logistic regression models estimated adjusted odds ratios (aORs) for macrosomia (>4000 g), postterm birth (>41 weeks), low birth weight (<2500 g), preterm birth (<37 weeks), large for GA, small for GA, and 5-minute APGAR (<7). RESULTS: Newborns of agricultural households (n = 6371) had a higher risk of macrosomia (aOR, 1.15; 95% CI, 1.05-1.26), large for GA (aOR, 1.12; 95% CI, 1.03-1.22), postterm birth (aOR, 1.20; 95% CI, 1.09-1.33), and low 5-minute APGAR (aOR, 1.39; 95% CI, 1.07-1.81), whereas low birth weight (aOR, 0.85; 95% CI, 0.76-0.96) and preterm birth (aOR, 0.82; 95% CI, 0.74-0.92) were inversely related. CONCLUSIONS: Having an agriculture working parent increased the likelihood of fetal overgrowth and low APGAR.
