LSU: Knowledge and Attitudes Towards Low Dose Computed Tomography Lung cancer Screening and Smoking Among African Americans—a mixed method study

According to Dr. Tung-Sung Tseng, associate professor at Louisiana State University Health Sciences Center (LSUHSC) School of Public Health, the purpose of this study is to investigate knowledge, attitudes, and smoking cessation needs for African Americans who receive low dose computed tomography (LDCT) in an effort to reduce the health burden of lung cancer.

The research team gathered data using a self-administered questionnaire and structured in-depth interview. Descriptive statistics were used to provide summary information on knowledge, attitude and smoking behaviors, and thematic analysis was used to analyze interview data. The sample size for both the quantitative and qualitative approach was fifteen. The results showed that 73 percent of participants were male, the mean age was 61.8 years old, and 66.7 percent of participants had an income less than $20,000. Eighty percent had an education level of high school or below and 73.3 percent were overweight or obese. Smoking history was long (mean years =39 SD =14.9), but the number of cigarettes smoked per day was low (mean =9.2 SD =7.3), and 64 percent of the patients had a low nicotine dependence. Assessment of knowledge and attitudes towards LDCT revealed that participants had a moderate knowledge score (mean =4.3 SD =2.6), and most had a positive attitude. All participants planned to quit smoking, with 73 percent planning to quit within the next 6 months.  The team concluded that African Americans who receive LDCT lung cancer screening in this study have a moderate/lower knowledge score and positive attitude towards LDCT.   Understanding the factors associated with smoking cessation among at-risk African American smokers will help reduce disparities in lung cancer burden and is important to improve health for medically underserved minority populations.

LSU: Studies Association Between Smoking and Neutrophil to Lymphocyte Ratio Among Prostate Cancer Survivors

An elevated neutrophil to lymphocyte ratio (NLR) has been proven as a vital predictor of progression and mortality for prostate cancer. Smoking is a risk factor for increasing NLR. Drs. Tung-Sung Tseng, Yu-Hsiang Kao along with a team of researchers from the Louisiana State University Health Sciences Center (LSUHSC) School of Public  Health examined the effect of smoking on NLR among prostate cancer survivors.

A total of 354 men adults aged ≥20 years old with prostate cancer were analyzed using the National Health and Nutrition Examination Survey (NHANES) 2005–2016 data. The primary outcome was NLR, which was classified into two levels: high (≥3) and low (<3). Sampling weighted logistic regressions were used for evaluating associations between smoking and NLR among prostate cancer survivors. The team found that 33.2 percent (n=111) of prostate cancer survivors had an elevated NLR. Prostate cancer survivors with a high NLR were older (mean 73.5 years old), non-Hispanic white (38.5 percent), higher income (poverty income ratio >1, 34.7 percent), and longer years after diagnosis (8.8 years) compared to counterparts with a low NLR.

Smoking status did not have a significant impact on NLR. The interaction test between race and smoking status was significant (P=0.04). Non-Hispanic black who were current smokers were observed more likely to have high NLR than never smokers [adjusted odds ratio (OR) =3.69, 95 percent CI: 1.36–9.99]. However, the effect of smoking on NLR was not observed among either non-Hispanic whites or other races. In conclusion: Non-Hispanic black prostate cancer survivors who were a current smoker were more likely to have NLR ≥3 compared to non-smokers. Smoking cessation could benefit these patients in prostate cancer management and reduce the risk of progression and mortality.

LSU: Continuity of Outpatient Care and Avoidable Hospitalization: a Systematic Review

Continuity of care (COC) is a core element of primary care, which has been associated with improved health outcomes. Hospitalizations for ambulatory care sensitive conditions (ACSCs) are potentially preventable if these conditions are managed well in the primary care setting. The team of researchers, including from Louisiana State University Health Sciences Center School of Public Health, Dr. Kao and Dr. Tung-Sung Tseng’s aim, was to conduct a systematic review of literature on the association between COC and hospitalizations for ACSCs. They used the Systematic literature review, a method which all published literature was searched for in PubMed and MEDLINE using PRISMA guidelines for collecting empirical studies. Studies published in English between 2008 and 2017 that measured the association between COC and at least one measure of ACSC hospitalizations were included in this review

Their results, a total of 15 studies met the inclusion criteria and applied claims data to examine the association between COC and ACSC hospitalizations. Most studies (93.3 percent) demonstrated a statistically significant association of higher COC in the outpatient setting with reduced likelihood of hospitalization for either all ACSCs or a specific ACSC. A strong association was observed among studies focusing on patients with a specific ACSC.  The team concluded that this systematic review identified an increased COC in outpatient care is associated with fewer hospitalizations for ACSCs. Increasing COC is favorable for patients who are managing a specific ACSC.

Racial and Income Disparities in Health-Related Quality of Life among Smokers with a Quit Attempt in Louisiana

February 13, 2019 – New Orleans, LA

In the recent study, “Racial and Income Disparities in Health-Related Quality of Life among Smokers with a Quit Attempt in Louisiana,” published in Medicina 2019, smoking was found to be associated with a lower health-related quality of life (HRQOL). However, there is little information about the association between HRQOL in relation to race, income, and smoking status. The present study aimed to assess the association between HRQOL and smoking status for those of different races and income levels.

Authorship and contribution to this research and publication  from the LSU Health Sciences Center School of Public Health includes current Fellow Yu-Hsiang Kao,  Dr. Tung-Sung Tseng, Mr. Michael D. Celestin, Jr. , Dr. Sarah Moody-Thomas from Behavioral & Community Health. Also, contributing to this research is Mrs. Krysten Jones-Winn from the Tobacco Control Initiative Program and  Dr. Qingzhao Yu from Biostatics.

This study’s conclusions state that racial and income disparities were evident with regards to HRQOL, with lower-income black or African Americans who were current smokers with a quit attempt having a lower HRQOL. Intervention programs for smoking cessation should target lower-income black or African American smokers who have a prior quit attempt and provide effective cessation services to help them quit smoking and improve their HRQOL.

LSU: Faculty and Researchers Used Emergency Department Data to Estimate Prevalence of Smoking in Young Adults

Faculty and researchers at the LSU School of Medicine (Drs. Stephen Kantrow and Sarah Jolley), Louisiana State University Health Sciences Center School of Public Health (Ms. Xinnan Wang, Dr. Tung-Sung Tseng, Dr. Dodie Arnold, Dr. Claudia Leonardi, Dr. Richard Scribner, Dr. Edward Trapido, Dr. Hui-Yi Lin), Ochsner Health System (Eboni Price Haywood) and the Louisiana Public Health Institute (Dr. Lisanne Brown) used emergency department (ED) data to estimate the prevalence of smoking in young adults. Most state or national surveys of smoking are limited in size- especially when looking at county level data, and phone based surveys have had decreasing responses. School based surveys are helpful, but limited by age.

The researchers used data from electronic health records (EHRs) for five EDs within U.S. Census-defined metropolitan New Orleans (New Orleans–Metairie, LA) for persons 18-24 years old. (15 percent of young adults are reported to have used EDs in the past year). Smoking status was available for 55,777 persons (91 percent of the total Emergency Departments); 61 percent were women, 55 percent were black, 35 percent were white, and 8 percent were Hispanic. One third of patients were uninsured. Most smokers used cigarettes (95 percent ). Prevalence of current smoking was 21.7 percent for women and 42.5 percent for men. Smoking prevalence was highest for substance use disorder (58 percent ), psychiatric illness (41 percent ) and alcohol use (39 percent ), and lowest for pregnancy (13.5 percent ). In multivariable analyses, male gender, white race, lack of health insurance, alcohol use, and illicit drug use were independently associated with smoking. Smoking risk among alcohol and drug users varied by gender, race, and/or age.

The BRFSS estimated 29 percent prevalence during the same time, and had data on 597 subjects aged 18–30 years. Although ED data are likely to overestimate tobacco use, the large sample size is useful- especially for stratum-specific estimates- particularly in a demographically diverse population. Dr. Stephen Kantrow, the lead investigator, stated ”this approach provides smoking data for a large sample of young adults in one metropolitan area, and may support longitudinal studies of smoking in high and low risk populations.

ASPPH | LSU: Association between Continuity of Care and Emergency Department Visits and Hospitalization in Senior Adults with Asthma-COPD Overlap

Dr. Tung-Tseng, associate professor of Louisiana State University Health Sciences Center School of Public Health behavioral and community health sciences, explains that the objective of the research was to investigate associations between continuity of care (COC) and emergency department (ED) visits and hospitalization for chronic obstructive pulmonary disease (COPD) or asthma among elderly adults with asthma-COPD overlap (ACO).

The study was performed using the Taiwan National Health Insurance research database. A total of 1141 ACO patients aged ≥65 years during 2005–2011 were observed and followed for two years. The Bice and Boxerman COC index (COCI) was used to evaluate COC by considering ambulatory care visits due to COPD or asthma in the first year; ED visits and hospitalization for COPD or asthma were identified in the subsequent year, respectively. The COCI was divided into three levels(COCI < 0.3= low, 0.3 ≤ COCI<1=medium, COCI = 1=high). The Cox model was used to estimate the hazard ratio (HR) for ED visits and hospital admissions due to COPD or asthma. The team concluded that increasing COC is beneficial for elderly patients with ACO in disease management.  Policy-makers could create effective pay-for-performance programs for the elderly ACO population to enhance COC and improve care outcomes.

LSUHSC SPH Study: Improving low-income residents’ utilization of farmers markets

Read the full news released featured in the AAAS and EurekAlert!, “Improving low-income residents’ utilization of farmers markets”

February 20, 2018

New Orleans, LA – A pair of studies conducted at LSU Health New Orleans School of Public Health found reasons and possible solutions to improve low-income residents’ access to fresh, local produce at farmers markets. The first study, published in the Journal of Public Health Research, available at, found a lack of awareness of the existence of farmers markets, and of discounts and benefits available to low-income residents among those who did know about farmers markets.

“Our study for the first time shows that one barrier to farmers market utilization is simply not being aware that they exist.,” noted Henry Nuss, PhD, Assistant Professor at LSU Health New Orleans School of Public Health.

The researchers developed a questionnaire to assess demographic information, awareness of farmers markets in New Orleans, food-purchasing behaviors, internet use, diet and preferences among a variety of marketing media. They found that nearly two-thirds (63%) of low-income participants had never been to a farmers market. The research team reported that 73% of participants did not know that farmers markets accept Supplemental Nutrition Assistance Program (SNAP) benefits, and 77% were not aware that patrons could receive additional discounts with SNAP purchases. The researchers then tested the feasibility of their novel, internet-based social marketing strategy, Healthy Roots for You.

The second study, published in Ethnicity & Disease, available at, built upon the first study. Its findings included that low-income residents have adequate access to the internet and a variety of social media channels and that web-based marketing could be a cost-effective and efficient way to not only increase awareness of farmers markets, but also that they are sources of affordable and nutritious local foods. Researchers found that the majority of participants had internet access via smart phones or home PCs and used social media and the internet frequently, often as a means of obtaining health-related information. The research team used data from the preliminary study to target low-income residents with tailored content for both those who had never been to a farmers’ market and to encourage future use among those who had been to one before.

“Most participants liked the sample Healthy Roots marketing media we shared with them and agreed that notifications via social media, email and a dedicated website would increase their awareness of farmers markets,” Dr. Nuss said.

Researchers say the importance of this research is that farmers markets are being underutilized by the at-risk community members they intend to help. This research is working to identify and remove barriers to improve health in these underserved populations.

“Farmers’ markets were originally established to provide fresh, healthy and affordable food to underserved communities,” Nuss noted. “Unfortunately, this is not a case of ‘if you build it they will come.’ What we’re seeing now is that we need to put the word out that farmers’ markets are there for low-income residents, and that the affordability and quality of fresh, LOCAL produce are better and healthier that what they’d find at retail chains.”


In addition to Nuss, the research teams also included Meg Skizim, MPH; Melinda Sothern, PhD; Ondrej Blaha; Tung-Sung Tseng, DrPH; Lauren Griffiths, MPH; Jonathan Joseph; Hasheemah Afaneh; and Lucio Miele, MD, PhD.

These research projects were supported by the National Institutes of Health, the Albert Schweitzer Fellowship, Hollygrove Market and Farm, Hollygrove community and LSU Health New Orleans School of Public Health.

LSU Program Director Awarded Grant to Develop an Interactive Voice Response System Intervention for Pregnant Smokers

Mr. Michael Celestin, Director of the Louisiana Tobacco Control Initiative and Instructor of Behavioral and Community Health Sciences at Louisiana State University Health Sciences Center School of Public Health, has been awarded pilot funding by the Louisiana Cancer Research Consortium to develop a culturally tailored intervention using Interactive Voice Response System (IVRS) technology to promote and maintain smoking cessation among socioeconomically disadvantaged pregnant women in Louisiana.

In the U.S., one in five women smoked the three months before pregnancy, one in ten smoked during the last three months of pregnancy, and one in seven smoked postpartum. Maternal smoking is associated with miscarriage, preterm delivery, restricted fetal growth, infant mortality, birth defects and ADHD in children. Socioeconomically disadvantaged pregnant women have a greater risk of smoking during and after pregnancy. Evidence-based cessation interventions exist to aid quit attempts, but few target pregnant smokers and enrollment in and utilization of cessation programs remain low.

IVRS technology will serve as an innovative approach to recruit and enroll pregnant smokers into various types of cessation treatment. “This study will use a mixed method approach to explore pregnant smoker’s knowledge, attitudes, beliefs, behaviors, and perspectives on the facilitators and barriers to smoking cessation,” Mr. Celestin said. “These findings will inform IVRS message development to promote cessation and triage ready-to-quit smokers for preferred treatment.”

Mr. Celestin will collaborate with co-investigators Dr. Tyra Toston-Gross, assistant professor in the Department of Public Health Sciences at Xavier University of Louisiana, as well as associate professor Dr. Tung-Sung Tseng and professor emeritus Dr. Sarah Moody-Thomas of Behavioral and Community Health Sciences at LSU.
