Health Information Seeking and Its Associated Factors Among University Students: A Case in a Middle-Income SettingYilma, Tesfahun M., Inthiran, Anushia, Reidpath, Daniel, Orimaye, Sylvester Olubolu 01 January 2017 (has links)
This paper aims to describe health information seeking behaviour and identify its associated factors among undergraduate university students in developing countries. An online survey is used to collect data from 138 students. The data is analysed using the multivariate logistic regression analysis method. Results reveal that a substantial number of students have sought health information mostly from the Internet. Health literacy, perceived susceptibility to health problems and alcohol consumption are found to be the significant factors influencing health information seeking behaviour. Results provide an understanding of health information seeking behaviour in developing countries.

Association Between per and Polyfluoroalkyl Substances and Markers of Inflammation and Oxidative StressOmoike, Ogbebor E., Pack, Robert P., Mamudu, Hadii M., Liu, Ying, Strasser, Sheryl, Zheng, Shimin, Okoro, Joy, Wang, Liang 01 May 2021 (has links)
Objectives: This study aimed to examine the association of Per and Polyfluoroalkyl substances (PFAS) and markers of chronic inflammation and oxidative stress. Methods: Using data (n = 6652) from the National Health and Nutrition Examination Survey (NHANES) 2005–2012, generalized linear models were used to examine the association between PFAS and inflammatory (ferritin, alkaline phosphatase, C-reactive protein, absolute neutrophil count and lymphocyte count) and oxidative stress (serum bilirubin, albumin and iron) per unit exposure to PFAS while adjusting for covariates. Study participants were those ≥20 years of age. Outcome variables were markers of chronic inflammation and oxidative stress and exposure variables were PFAS. Resullts: Percentage change in Perfluorohexane sulfonic acid (PFHxS), Perfluorononanoic acid (PFNA), Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonic acid (PFOS), and Perfluorodecanoic acid (PFDA) were all significantly associated with percentage increases in lymphocyte counts, beta (95% confidence interval); 0.04(0.02,0.05), 0.04(0.02,0.05), 0.05(0.03, 0.07), 0.04(0.03,0.05), 0.03(0.13,1.23) and with percentage increases in serum iron 0.07(0.05,0.09), 0.04(0.02,0.07), 0.10(0.07,0.12), 0.05(0.03,0.07), 0.04(0.02,0.06) and increased serum albumin 0.02(0.02,0.02), 0.02(0.02,0.03), 0.03(0.03,0.04), 0.02(0.017, 0.025), 0.01 (0.01, 0.05). Only PFHxS, PFNA, PFOA and PFOS were associated with percentage increases in serum total bilirubin 0.04(0.03,0.05), 0.02(0.00,0.03), 0.06(0.04,0.08), 0.03(0.02,0.05). Similar results were obtained for categorical quintile analysis with PFOA showing a significant trend (P < 0.001) with lymphocyte count, serum iron, serum total bilirubin and serum albumin. Trend for neutrophil count was not significant (p = 0.183). Conclusion: Per and Polyfluoroalkyl substances are associated with markers of chronic inflammation and oxidative stress. Increased exposure leads to increase in serum concentration of these markers meaning these chemicals are associated with both chronic inflammation and oxidative stress.

A Cross-Sectional Study of the Association Between Perfluorinated Chemical Exposure and Cancers Related to Deregulation of Estrogen ReceptorsOmoike, Ogbebor E., Pack, Robert P., Mamudu, Hadii M., Liu, Ying, Wang, Liang 01 May 2021 (has links)
Background: Environmental exposures acting through different mechanisms have been linked with a number of cancers. Perfluoroalkyl chemicals (PFCs) are endocrine disrupting chemicals affecting estrogen homeostasis. Objectives: We examined the association between PFCs and a group of estrogen related cancers and explored if increased non-occupational exposure was associated with increased odds of developing these cancers. We also explored which of these chemical exposures was more correlated with each cancer. Methods: Using data from the National Health and Nutrition Examination Survey (NHANES), we selected participants ≥ 20 years of age. Our outcome variable was presence or absence of breast, prostate, ovarian and uterine cancer (yes/no); our exposure variables were serum PFCs. Logistic regression models were used in investigating the association between PFCs and cancer types and between quartiles of PFCs exposure concentrations and presence or absence of cancer while adjusting for covariates. Discriminant analysis was used to assess the correlation between individual PFCs compounds and individual cancer types. Results: PFCs were associated with increased odds of ovarian cancer; PFOA: 1.02(1.01, 1.02), PFOS: 1.01 (1.012, 1.013), PFHS 1.031 (1.030, 1.033), PFDE: 1.29(1.27, 1.30) and increased odds of breast cancer; PFOA: 1.089(1.089, 1.09), PFOS: 1.011(1.011, 1.011), PFNA: 1.031(1.030, 1.033), PFHS: 1.02 (1.02, 1.02), PFDE: 1.19(1.18, 1.19). PFCs were not associated with increased odds of prostate or uterine cancers. Comparing the odds in quartile 4 to quartile 1 for ovarian cancer, PFOA: 1.77(1.75,1.79), PFOS: 2.25(2.22, 2.28), PFHS: 1.86(1.84, 1.88), PFDE: 2.11(2.09, 2.14). For breast cancer, PFOA: 2.30(2.28, 2.31), PFOS: 1.47(1.46, 1.48), PFNA: 1.04(1.03, 1.05), PFHS:7.07(6.97,7.17), PFDE: 1.38(1.37, 1.39). PFOA was more correlated with breast cancer (0.7) and PFHS was more correlated with ovarian cancer (0.9). Discussion: PFCs were associated with increased odds of ovarian and breast cancers with a positive dose-response relationship. PFOA was more correlated with breast cancer and PFHS more with ovarian cancer.

Thoughts and Consideration Regarding Immigrant Clinicians: Is Cultural Preservation Influencing Providers’ Practice in HPV Vaccination?Ashing, Kimlin T., Ragin, Camille, Ariyo, Oluwatosin, Amini, Arya 01 January 2021 (has links)
Immigrant clinicians are vital to population healthcare delivery and therefore population health. One in four physicians in the United States are foreign-born and notably represented in family and pediatric medicine–specialties charged with administering childhood/adolescent vaccines, such as Human Papillomavirus vaccine (HPVV). Our examination suggests there may be unique cultural and socialization factors that influence clinician HPVV recommendation practice; however, immigrant clinicians have not been adequately engaged within the national HPVV agenda. Given the volume and significance of immigrant clinicians, engagement of these clinicians, in both community and nation-wide efforts to increase HPVV, is a necessary step for improving and achieving the national health goal of optimizing HPVV for cancer prevention.

Understanding the association between susceptibility to smoke e-cigarettes and the actual use of e-cigarette among school-going youths in rural appalachiaNwabueze, Christian, Wang, Liang, Osedeme, Fenose, McNabb, Michelle, Yang, Joshua, Boghozian, Rafie, Wood, David, Mamudu, Hadii 27 October 2020 (has links)
Background: The Central Appalachian region of the United States is disproportionately burdened with high prevalence of tobacco use and tobacco-induced diseases. Efforts to address tobacco use in the region have become complicated with uptake of Electronic Nicotine Products (ENPs), including e-cigarettes, among adolescents and young adults. The high prevalence of tobacco use, and the history of tobacco production have created a high-risk environment for the use of tobacco and ENP among adolescents in the region. However, research on how susceptibility to use e-cigarettes among school-going adolescents translates to usage is sparse. This study aimed to explore the association between susceptibility to use e-cigarette and e-cigarette use in school-going adolescents in Appalachian Tennessee.
Methods: Data (N=399) was collected from high school students in an Appalachian Regional Commission (ARC)-designated distressed County in Appalachian Tennessee. We ascertain the study’s outcomes (current e-cigarette use), the exposure (susceptibility to use e-cigarette) and co-variates (grade, sex, age at first use of tobacco, perception of the danger of smoking, parental counseling) using validated questions. Descriptive statistics and multi-variable logistics analyses were performed. The Odds Ratios (ORs) along with Confidence Intervals (CI) have been reported.
Results: 15.5% of the population were current e-cigarette users and 25.93% were identified as susceptible to use e-cigarettes. Susceptibility to use e–cigarette was associated with increased odds of the current use of e-cigarette (OR=6.40, CI=4.18–9.77). In addition, age at first use of tobacco (OR = 0.42, 95%CI =0.32 – 0.56) was associated with reduced odds of the current use of e-cigarette, while intention to smoke e-cigarette (OR =6.46, CI =3.63 -11.49) was associated with increased odds of the current use of e-cigarette.
Conclusion: Susceptibility to use e-cigarette was positively associated with the current use of e-cigarette among school going adolescents. Future longitudinal studies with large sample size are warranted to confirm the association.

A Cross-Sectional Analysis of Tobacco Use and Concurrent Alcohol and Substance Use Among Patients Living with HIV/HCV Co-infection: Findings from a Large Urban Tertiary CenterSims, Omar T., Jackson, Asti, Guo, Yuqi, Truong, Duong N., Odame, Emmanuel A., Mamudu, Hadii M. 01 January 2020 (has links)
This study aimed to assess the prevalence of and factors associated with tobacco use among patients living with HIV/HCV co-infection. Patient reported outcomes (PROs) were analyzed of patients living with HIV/HCV co-infection (n = 313) who presented for clinical evaluation and treatment of HCV between 2013 and 2017 at a university-affiliated HIV/HCV Co-infection Clinic. The prevalence of tobacco use in patients living with HIV/HCV co-infection was 48%. Compared to non-smokers, a higher proportion of tobacco smokers had substance use disorders and concurrent alcohol and substance use. In the multivariate analysis, concurrent alcohol and substance use was positively associated with tobacco use. The findings suggest clinical interventions are urgently needed to reduce tobacco use among patients living with HIV/HCV co-infection—a doubly-vulnerable immunocompromised population. Otherwise, failed efforts to dedicate resources and targeted behavioral interventions for this respective population will inhibit survival—especially considering the recent and evolving COVID-19 pandemic.

Young Adults' Human Papillomavirus–Related Knowledge: Source of Medical Information MattersBenavidez, G., Asare, M., Lanning, B., Ylitalo, K., Fakhoury, C., Thompson, N., Boozer, K., Mamudu, H. M. 01 May 2020 (has links)
Objectives: Few studies examine the influence that different sources of medical information has on human papillomavirus (HPV)–related knowledge. We examined the relationship between the primary source of medical information and knowledge about HPV in young adults aged 18–26 years. Study design: This study used cross-sectional data from the Health Information National Trends Survey. Methods: Respondents (n = 404) self-reported their knowledge about HPV-related diseases and vaccinations and their sources of medical information. Sources of medical information included electronic/print media, family/friends, or a healthcare provider. Bivariate and multivariate analyses were used to examine the association between the source of information and HPV knowledge. Results: Fifty-six percent of respondents used electronic or print media as their primary source of medical information. A greater proportion of Hispanic (40.0%) and black (36.0%) respondents received medical information from their family/friends than white respondents (20.0%). Respondents who received medical information from family/friends had 4.34 (95% confidence interval [CI]: 2.14, 8.79), 4.06 (95% CI: 2.05, 8.04), and 2.35 (95% CI: 1.10, 5.04) times higher odds than those who received information from healthcare providers of not knowing that HPV causes cervical cancer, knowing HPV is a sexually transmitted infection, and hearing about the HPV vaccine, respectively. Conclusion: Source of medical information was significantly associated with knowledge of HPV. Receiving medical information from family/friends negatively influenced young adults' HPV knowledge. These findings may guide future interventions to target peer and familial influence on medical decisions.

Increased Prevalence in Alzheimer Disease in the Northeast Tennessee Region of the United StatesOrimaye, Sylvester O., Southerland, Jodi L., Oke, Adekunle O., Ajibade, Aderonke 01 July 2020 (has links)
This study describes the changes in prevalence odds ratios (PORs) for Alzheimer disease (AD) in the northeast Tennessee region (NTR) during a 3-year period, describes the statistical assessment process, and critically assesses the database from which the statistical association was derived. The article also examines several beliefs pertinent to the clinical management of AD in the NTR from the perspective of professionals delivering services. Methods We extracted prevalence data for NTR counties for 2013, 2014, and 2015 from the Centers for Medicare and Medicaid Services Geographic Variation Public Use File. We used the crude prevalence and the 2010 US Census Data fixed population for each county to compute the POR. The 2013 Economic Research Service Rural-Urban Continuum Codes were used to identify rural and urban counties in the NTR. We collected primary data on the perceived observation of the increasing prevalence in the NTR during the last 3 years and barriers to early diagnosis through an online survey from 44 experts and professionals working in AD-related fields within the NTR. Results The PORs of AD in rural counties in NTR increased by 18.3%, 4.7%, and 19% compared with urban counties for 2013, 2014, and 2015, respectively. The POR of AD for the entire NTR region increased by 22.7%, 22.5%, and 21.2% compared with other regions in Tennessee for 2013, 2014, and 2015, respectively. Compared with 2012, 68.4% of respondents currently work with more individuals with AD; 71.8% reported that the NTR has a higher number of late-stage diagnoses of AD. A total of 92.3% strongly agreed that early detection of AD is important, and 95% agreed that early diagnosis could prolong the lives of patients with AD; 51.2% were unaware of existing AD screening services. Reported barriers were denial, lack of patient awareness, inefficient screening methods, communication, and lack of community resources. Conclusions Increased prevalence of AD among inhabitants in the NTR and identified barriers to early screening or diagnosis in the management of AD were identified. Access to early screening techniques must be prioritized in deprived areas within the NTR. Healthcare providers and medical professionals in the NTR must be well equipped with the required training and resources to respond adequately to the increasing prevalence of AD.

Association Between Smoking Status and Homocysteine Levels and Possible Effect Modification by Cholesterol and OestradiolOmoike, Ogbebor Enaholo, Paul, Timir K., Ridner, Stanley L., Awasthi, Manul, Harirforoosh, Sam, Mamudu, Hadii M. 17 February 2020 (has links)
Introduction: This study aimed to examine the association of smoking status with homocysteine levels and to determine whether the association is modified by oestradiol or cholesterol. Methods: Data (N = 4580) were obtained from National Health and Nutrition Examination Survey 2003–2004 with analysis done in 2018 on adults aged ≥20 years. The outcome was homocysteine; smoking status was the exposure variable and categorized as current, former or never smoker. Generalized linear models were used to examine the associations between smoking status and homocysteine levels, while assessing the impact of oestradiol and cholesterol. Results: After adjusting for age, sex, ethnicity, education and income level, homocysteine levels did differ by smoking status ((current smokers versus never smokers: β: 0.18 CI: 0.00, 0.36), (former smokers: β: 0.10 CI: –0.09, 0.28)). The addition of oestradiol as an interaction term in adjusted models was associated with a 16.6% increase in homocysteine levels when compared to models without the interaction term. Oestradiol but not cholesterol did moderate the association between smoking status and homocysteine levels. Discussion and conclusions: Homocysteine levels did differ across smoking status after adjusting for confounders. Oestradiol did moderate the relationship between homocysteine and smoking status.
