Socio-cultural Conceptions and HIV-related TB among Haitian Immigrants in Broward County, Florida: A Brief Historical Insight, 1995-2002

This study deals with tuberculosis (TB), human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) in Broward County, South Florida. Theoretically, it demonstrates the existing co-infection between TB and HIV that provokes HIV-related TB or AIDS. Additionally, it indicates that AIDS is provoked by HIV co-infection with all opportunistic infections. Nine (9) qualitative interviews and one focus group conducted with 12 Haitian patients and TB control program workers at Fort Lauderdale Health Care Center allowed to understand the connection between TB and HIV, and the patients’ socio-cultural conceptions about HIV-related TB. Then, the study reveals that the prevalence of TB and HIV-related TB has every year a dramatic increase among foreign-born individuals including Haitian residents. To determine this prevalence, the Broward County Health Department charts of 778 reported TB and HIV co-infection cases for the last 6 years were analyzed along with the qualitative interviews. Finally, the study shows that the indicated prevalence is due to both Haitian immigrants’ socio-cultural conceptions and reactions vis-à-vis the TB screening, prevention measures, and treatment.

Using Ecological Diversity Analyses to Characterize the Availability of Healthy Food and Socio-Economic Food Deserts

“Food deserts” are usually defined as geographic areas without local access to fresh, healthy food. We used community ecology statistics in supermarkets to quantify the availability of healthy food and to potentially identify food deserts as areas without a diverse selection of food, rather than a binary as to whether fresh food is present or not. We test whether produce diversity is correlated with neighborhood income or demographics. Abundance and diversity of fresh produce was quantified in supermarkets in Broward County, Florida, USA. Neighborhood income level and racial/ethnic makeup were retrieved from the U.S. Census and American Community Survey. Although diversity varied, there were no communities that had consistently less available fresh food, although the percent of a neighborhood identifying as “white” was positively correlated with produce diversity. There may be fewer choices in neighborhoods with a higher proportion of minorities, but there were no consistent patterns of produce diversity in Broward County. This method demonstrates an easy, inexpensive way to characterize food deserts beyond simple distance, and results in precise enough information to identify gaps in the availability of healthy foods.

Examining equity in an elementary school computer science intervention using component-based research

This article reports on implementation of a problem-based learning intervention developed with the intention of finding time for computer science (CS) in the elementary school day. This study investigated differences in effects on students in particular socio-demographic groups using a quasi-experimental design. We first provide an overview of the perennial problem of group differences or “gaps” in student outcomes. Then we illustrate how, using component-based research (CBR), we moved beyond the question of whether the intervention worked, to focus on which parts of the intervention worked, for whom, and under what conditions. Using hierarchical linear modeling, this study draws from a sample of 16 elementary schools with 321 teachers and 5791 students in Broward County, Florida, the sixth largest school system in the United States. This study complements a previous paper (Authors, 2020), which examined associations between intervention components and student outcomes by investigating how outcomes differ for students in different socio-demographic groups and whether the presence of particular intervention components amplify or reduce differences. Through CBR, our work illustrates that CS interventions which may appear to benefit students overall, may be less beneficial or even detrimental to particular groups.

Establishing a framework of a watershed-wide screening tool to support the development of watershed-based flood protection plans for low-lying coastal communities

Flood risk analysis is the instrument by which floodplain and stormwater utility managers create strategic adaptation plans to reduce the likelihood of flood damages in their communities, but there is a need to develop a screening tool to analyze watersheds and identify areas that should be targeted and prioritized for mitigation measures. The authors developed a screening tool that combines readily available data on topography, groundwater, surface water, tidal information for coastal communities, soils, land use, and precipitation data. Using the outputs of the screening tool for various design storms, a means to identify and prioritize improvements to be funded with scarce capital funds was developed, which combines the likelihood of flooding from the screening tool with a consequence of flooding assessment based on land use and parcel size. This framework appears to be viable across cities that may be inundated with water due to sea-level rise, rainfall, runoff upstream, and other natural events. The framework was applied to two communities using the 1-day 100-year storm event: one in southeast Broward County with an existing capital plan and one inland community with no capital plan.

A Logistic Regression Analysis to Assist Welfare Recipients Attaining Employment

This study reports on an experiment using logistic regression to uncover the preponderant factors influencing the likelihood of attaining employment by a welfare recipient in Broward County, Florida. Our study considers whether profiling the participants and tailoring the workforce development services based on their respective profiles can increase their likelihood of finding employment (Black et al., 2003). The study finds that our econometric model predicted the probability of employment with reasonably strong reliability. This finding is in alignment with the Welfare Profiling Model of Michigan’s (Barnow et al., 2012; Eberts, 1997;2002) and the Factors Influencing AFDC Duration and Labor Market Outcomes Research Study of Texas (Schexnayder et al., 1991). More specifically, the results indicate that education and prior employment history are significant factors increasing the likelihood of departing from welfare and achieving employment. Furthermore, the study concludes that the number of children, participant’s age, and the ethnicity of the welfare recipient also play a role in breaking away from welfare. The results from the experiment show that using the econometric model to assign services to individuals increases the likelihood of finding employment from 11% to 24% on average. This is a very encouraging finding since it motivates researchers to perform further research in this area of study.

Potential Risk Factors for Childhood Overweight and Obesity Among WIC Participating Preschool Children

Objectives To identify risk factors associated with the risk for overweight/obesity in preschool children ages 3 up to 5 years participating in the Broward County Special Supplementation Nutrition Program for Women, Infants, and Children (WIC). Methods Cross-sectional data were collected from all 7 Broward County Health Department WIC clinics over 4 months via a researcher-administered questionnaire. Additional data were extracted from the WIC data system. Children were classified into weight categories following the CDC's BMI-for-age percentiles, which were further combined into under/normal weight and overweight/obese. Results A total of 197 participants [90 boys (45.7%) and 107 girls (54.3%)] were included. From those, 68% were overweight/obese and 32% under/normal weight. Sugar sweetened beverage (SSB) intake was significantly greater in the overweight/obese group (7.45 ± 8.71 vs. 4.60 ± 6.64 oz/d, P = 0.024). Fruits were consumed daily by 67% of the children, and vegetables by 35%, with no significant association with weight category. Breakfast was skipped at least once/week by 16.5% of the children, independent of body weight. On average, children had 2.3 h/d of screen time and were physically active for 37.9 min/d. While screen time was not significantly different by weight category, children in the under/normal weight group were significantly more physically active when compared to their counterparts (41.9 ± 29.3 vs. 29.3 ± 27.0 min/d, P = 0.004). Only 15.2% of parents/guardians of overweight and 43.3% of obese children identified their child as being too big. Mean birth weight for overweight/obese children was significantly higher (7.41 ± 1.12 vs. 7.04 ± 1.17 lbs, P = 0.038). On a logistic regression model, SSB intake, physical activity, and birth weight were significant predictors of overweight/obesity. Conclusions Physical activity was negatively correlated with the risk of overweight/obesity, while the intake of SSB and birth weight were positively correlated. In addition, most participants failed to perceive their overweight/obese child as such. This study points out important factors to be considered in obesity prevention interventions in this population. Funding Sources AC was supported by a NIH/NIGMS R25 grant. The FIU Dietetics and Nutrition research foundation supported the study.

Mottled Water Hyacinth Weevil Neochetina eichhorniae Warner (Insecta: Coleoptera: Curculionidae)

Sometimes referred to as the ‘mottled water hyacinth weevil’, Neochetina eichhorniae Warner is a weevil that attacks the invasive, aquatic plant, water hyacinth, Eichhornia crassipes (Mart.) Solms. Water hyacinth is considered one of the most destructive plants in aquatic ecosystems in the United States and, as a result, is listed in both the federal noxious weed list and Florida’s list of prohibited aquatic plants. Neochetina eichhorniae is host specific and causes substantial damage to water hyacinth, making it a valuable biological control agent for this invasive weed in many parts of the world. The insect was first introduced into the United States from Argentina in 1972, when scientists released the insect in Broward County, Florida, to manage water hyacinth (Perkins 1973). Since then, the insect has been introduced in more than three dozen countries worldwide (Winston et al. 2014). Post-introduction studies indicate the insect substantially suppresses the growth of water hyacinth, significantly reducing biomass, flowers production, and water surface coverage (Grodowitz et al. 1991, Center et al. 1999, Tipping et al. 2014, Nesslage et al. 2016) and the need for herbicide applications (Haag 1986).

COVID-19 infection among first responders in Broward County, Florida, March–April 2020

Background First responders (FRs) may have a significant risk of coronavirus 19 (COVID-19) infection than the general population due to job-related exposures. We aimed to determine the prevalence and exposure patterns of COVID-19 among FRs. Methods Between March and April 2020, FRs in Broward County, Florida, were screened for COVID-19 infection by real-time reverse transcription polymerase chain reaction assay using nasopharyngeal swabs. Demographics and COVID-19 positive rate of the FRs were summarized. Results A total of 3375 FRs were screened for COVID-19 infection. The median age of FRs tested was 42 years (IQR 33–52 years), and 1464 (43.4%) were men. A total of 2902 (85.9%) were asymptomatic, and 473 (14.1%) reported symptoms associated with COVID-19. Overall, 289 (8.6%) were positive, with the highest rates among the age between 25 and 49 years. Of those testing positive, 235 (81.3%) were asymptomatic. Fourteen days after their first positive test, 81 (69.8%) of the 116 asymptomatically infected FRs were negative, and 35 (30.2%) remained positive and asymptomatic. Conclusions The FRs in Broward County, FL, had an overall infection rate of 8.6% at the time of COVID-19 testing, and asymptomatic FRs accounted for 81.3% of infection. Active surveillance should be focused on the asymptomatic FRs with COVID-19.
