RESUMO

BACKGROUND: Black older-teenaged women have disproportionately high rates of sexually transmitted infections (STI) and unintended pregnancy (UTP). Internet-based interventions can be delivered to large groups of people in a relatively inexpensive manner. In this randomized trial, we examine the efficacy of an evidence-based STI/UTP prevention intervention adapted for older teens and for Internet delivery. METHODS: Black women aged 18-19 years who were not pregnant/seeking to become pregnant were enrolled (n = 637) and randomized to an 8-session intervention or attention control and were followed up at 6/12 months postintervention. The primary outcome was defined as uptake of reliable contraceptives. Other secondary outcomes were examined, including intention to use condoms, intention to use reliable contraception, and STI or pregnancy rates. RESULTS: Overall, at baseline, reliable contraception was 54.8% and dual protection was 29.4%, and the prevalence of STI was 11.1%. Participants were similar by arm for most factors considered. Participation and follow-up rates were excellent (60.9% and 80.3%). There was no statistically significant difference in uptake of reliable contraception for intervention versus controls at 6 months (1.45 [0.99-2.12]) or 12 months (1.33 [0.92-1.91]). At 6 months, several secondary outcomes were improved/trended toward improvement in intervention compared with control, but this effect waned by 12 months, except for intention to use condoms which remained improved. CONCLUSION AND RELEVANCE: The intervention was efficacious for increasing some self-reported UTP and STI prevention behaviors, which waned over time, and the intervention had minimal impact on STI or pregnancy rates suggesting that this type of online intervention may need additional components.

RESUMO

Patterns and correlates of substance use among urban African American young women (ages 18-19, n = 459) were examined. Four patterns were identified: no/infrequent alcohol and marijuana use (64.9%); recent alcohol only use (18.2%); recent marijuana only use (7.9%); and recent alcohol and marijuana use (9.0%). Having a recent male sexual partner and a history of sexual coercion were associated with increased odds of marijuana-only and dual use. Greater family support and childhood sexual abuse were associated with increased odds of alcohol-only use. Results suggest that sexual relationships and history of abuse/coercion are important factors in young African American women's substance use.

RESUMO

The ability to anticipate and respond appropriately to the challenges and opportunities present in our environments is critical for adaptive behavior. Recent methodological innovations have led to substantial advances in our understanding of the neurocircuitry supporting such motivated behavior in adulthood. However, the neural circuits and cognitive processes that enable threat- and reward-motivated behavior undergo substantive changes over the course of development, and these changes are less well understood. In this article, we highlight recent research in human and animal models demonstrating how developmental changes in prefrontal-subcortical neural circuits give rise to corresponding changes in the processing of threats and rewards from infancy to adulthood. We discuss how these developmental trajectories are altered by experiential factors, such as early-life stress, and highlight the relevance of this research for understanding the developmental onset and treatment of psychiatric disorders characterized by dysregulation of motivated behavior.

RESUMO

Introduction. While school-based kitchen garden programs are shown to improve fruit and vegetable consumption and knowledge among children, there has been little research on participant perceptions of these programs, specifically among minority populations that are disproportionately affected by and at high risk for overweight and obesity. This qualitative study examined the perceptions of and values associated with participation in school-based kitchen garden programs implemented through Edible Schoolyard New Orleans in low-income, predominantly African American schools in New Orleans, Louisiana. Method. Qualitative data were collected through semistructured focus group discussions with key stakeholder groups at schools offering Edible Schoolyard New Orleans. Results. A total of 10 focus groups were conducted across 4 middle schools with students (n = 27), parents (n = 17), and teachers (n = 17). Four primary themes emerged during data analysis: development of life skills, food and health, family and community, and experiential and participatory learning. Conclusions. To strengthen the sustainability and potential impact of school-based kitchen garden programs, future intervention strategies should place specific emphasis on the themes that emerged from this study. School-based kitchen garden programs may be a promising strategy to positively influence the individual, social, and physical environmental factors that contribute to overweight and obesity in low-income, African American communities.

RESUMO

Objectives Despite significant investments in Maternal and Child Health (MCH), the United States still lags behind other countries in key MCH indicators. A well-trained workforce is needed to improve MCH. The Division of MCH Workforce Development of HRSA's Maternal and Child Health Bureau provides funding to schools of Public Health to support Centers of Excellence in MCH, which is focused on preparing the next generation of MCH leaders through specialized training and mentorship. One such center, the Tulane Center of Excellence in MCH (CEMCH), is housed at the Tulane University School of Public Health and Tropical Medicine. This study evaluated the perceived effectiveness and acceptability of the CEMCH leadership training program. Methods A mixed-methods approach was used, consisting of semi-structured interviews and quantitative surveys which were analyzed through inductive methods based in grounded theory and non-parametric methods respectively. Results Results indicated an overall high level of program satisfaction by all stakeholders. Mentorship and personal attention emerged as an important benefit for both former and current Scholars. The opportunity to gain real-world understanding of MCH work through program activities was an added benefit, although these activities also presented the most challenges. Community stakeholders generally did not view the program as providing immediate organizational benefit, but recognized the distal benefit of contributing to a well-trained MCH workforce. Conclusions for Practice These results will be used to inform other MCH training programs and strengthen Tulane's CEMCH. A well-trained MCH workforce is essential to improving MCH, and high-quality training its foundation.

RESUMO

INTRODUCTION: Argentina and Uruguay have a high prevalence of smoking during pregnancy. However, and despite national recommendations, pregnant women are not routinely receiving cessation counseling during antenatal care (ANC). We evaluated a multifaceted strategy designed to increase the frequency of pregnant women who received a brief smoking cessation counseling based on the 5As (Ask, Advise, Assess, Assist, and Arrange). METHODS: We randomly assigned (1:1) 20 ANC clusters in Buenos Aires, Argentina and Montevideo, Uruguay to receive a multifaceted intervention to implement brief smoking cessation counseling into routine ANC, or to receive no intervention. The primary outcome was the frequency of women who recalled receiving the 5As during ANC at more than one visit. Frequency of women who smoked until the end of pregnancy, and attitudes and readiness of ANC providers towards providing counseling were secondary outcomes. Women's outcomes were measured at baseline and at the end of the 14- to 18-month intervention, by administering questionnaires at the postpartum hospital stay. Self-reported cessation was verified with saliva cotinine. The trial took place between October 03, 2011 and November 29, 2013. RESULTS: The rate of women who recalled receiving the 5As increased from 14.0% to 33.6% in the intervention group (median rate change, 22.1%), and from 10.8% to 17.0% in the control group (median rate change, 4.6%; P = .001 for the difference in change between groups). The effect of the intervention was larger in Argentina than in Uruguay. The proportion of women who continued smoking during pregnancy was unchanged at follow-up in both groups and the relative difference between groups was not statistically significant (ratio of odds ratios 1.16, 95% CI: 0.98-1.37; P = .086). No significant changes were observed in knowledge, attitudes, and self-confidence of ANC providers. CONCLUSIONS: The intervention showed a moderate effect in increasing the proportion of women who recalled receiving the 5As, with a third of women receiving counseling in more than one visit. However, the frequency of women who smoked until the end of the pregnancy was not significantly reduced by the intervention. IMPLICATIONS: No implementation trials of smoking cessation interventions for pregnant women have been carried out in Latin American or in middle-income countries where health care systems or capacities may differ. We evaluated a multifaceted strategy designed to increase the frequency of pregnant women who receive brief smoking cessation counseling based on the 5As in Argentina and Uruguay. We found that the intervention showed a moderate effect in increasing the proportion of women receiving the 5As, with a third of women receiving counseling in more than one visit. However, the frequency of women who smoked until the end of the pregnancy was not significantly reduced by the intervention.

RESUMO

INTRODUCTION: The 5A's (Ask, Advise, Assess, Assist, and Arrange) strategy, a best-practice approach for cessation counseling, has been widely implemented in high-income countries for pregnant women; however, no studies have evaluated implementation in middle-income countries. The study objectives were to assess smoking patterns and receipt of 5A's among pregnant women in Buenos Aires, Argentina and Montevideo, Uruguay. METHODS: Data were collected through administered questionnaires to women at delivery hospitalizations during October 2011-May 2012. Eligible women attended one of 12 maternity hospitals or 21 associated prenatal care clinics. The questionnaire included demographic data, tobacco use/cessation behaviors, and receipt of the 5A's. Self-reported cessation was verified with saliva cotinine. RESULTS: Overall, of 3400 pregnant women, 32.8% smoked at the beginning of pregnancy; 11.9% quit upon learning they were pregnant or later during pregnancy, and 20.9% smoked throughout pregnancy. Smoking prevalence varied by country with 16.1% and 26.7% who smoked throughout pregnancy in Argentina and Uruguay, respectively. Among pregnant smokers in Argentina, 23.8% reported that a provider asked them about smoking at more than one prenatal care visit; 18.5% were advised to quit; 5.3% were assessed for readiness to quit, 4.7% were provided assistance, and 0.7% reported follow-up was arranged. In Uruguay, those percentages were 36.3%, 27.9%, 5.4%, 5.6%, and 0.2%, respectively. CONCLUSIONS: Approximately, one in six pregnant women smoked throughout pregnancy in Buenos Aires and one in four in Montevideo. However, a low percentage of smokers received any cessation assistance in both countries. Healthcare providers are not fully implementing the recommended 5A's intervention to help pregnant women quit smoking.

RESUMO

Evidence of bias of self-reported smoking cessation during pregnancy is reported in high-income countries but not elsewhere. We sought to evaluate self-reported smoking cessation during pregnancy using biochemical verification and to compare characteristics of women with and without biochemically confirmed cessation in Argentina and Uruguay. In a cross-sectional study from October 2011 to May 2012, women who attended one of 21 prenatal clinics and delivered at selected hospitals in Buenos Aires, Argentina and Montevideo, Uruguay, were surveyed about their smoking cessation during pregnancy. We tested saliva collected from women <12 h after delivery for cotinine to evaluate self-reported smoking cessation during pregnancy. Overall, 10.0% (44/441) of women who self-reported smoking cessation during pregnancy had biochemical evidence of continued smoking. Women who reported quitting later in pregnancy had a higher percentage of nondisclosure (17.2%) than women who reported quitting when learning of their pregnancy (6.4%).

RESUMO

Secondhand smoke (SHS) exposure has negative effects on maternal and infant health. SHS exposure among pregnant women in Argentina and Uruguay has not been previously described, nor has the proportion of those who have received screening and advice to avoid SHS during prenatal care. Women who attended one of 21 clusters of publicly-funded prenatal care clinics were interviewed regarding SHS exposure during pregnancy at their delivery hospitalization during 2011-2012. Analyses were conducted using SURVEYFREQ procedure in SAS version 9.3 to account for prenatal clinic clusters. Of 3,427 pregnant women, 43.4 % had a partner who smoked, 52.3 % lived with household members who smoked cigarettes, and 34.4 % had no or partial smoke-free home rule. Of 528 pregnant women who worked outside of the home, 21.6 % reported past month SHS exposure at work and 38.1 % reported no or partial smoke-free work policy. Overall, 35.9 % of women were exposed to SHS at home or work. In at least one prenatal care visit, 67.2 % of women were screened for SHS exposure, and 56.6 % received advice to avoid SHS. Also, 52.6 % of women always avoided SHS for their unborn baby's health. In summary, a third of pregnant women attending publicly-funded prenatal clinics were exposed to SHS, and only half of pregnant women always avoided SHS for their unborn baby's health. Provider screening and advice rates can be improved in these prenatal care settings, as all pregnant women should be screened and advised of the harms of SHS and how to avoid it.

RESUMO

BACKGROUND: Comprehensive tobacco advertising/promotion bans are effective against adolescent smoking but many developing countries have implemented only partial bans. This study examines the association between advertising/promotions exposure and adolescent cigarette smoking risk in North Africa, and possible mediation of this association by parent and peer smoking. METHODS: Adolescent data (n=12 329) from the Global Youth Tobacco Survey were analyzed (Libya, 2007; Egypt, 2005; Morocco, 2006; Tunisia 2007; and Sudan, 2005). Current smoking (any cigarette use in the past 30 days) and never-smokers' initiation susceptibility (composite of openness to accepting a cigarette from a friend and intention to start smoking in the next year) outcomes were examined. Advertising/promotion exposures included media and in-person contacts. Weighted univariate, bivariate and multivariable analyses were conducted. RESULTS: Current smoking prevalence ranged from 5.6% (Egypt) to 15.3% (Tunisia) among boys, and 1.1% (Libya and Egypt) to 2.0% (Morocco and Sudan) among girls. Initiation susceptibility ranged from 14.1% (Sudan) to 25.0% (Tunisia) among boys, and from 13.3% (Sudan) to 15.0% (Libya) among girls. Ninety-eight percent of adolescents reported exposure to at least one type of advertising/promotion. In multivariable analyses adjusting for demographics, each type of advertising/promotion was significantly and positively associated with boys' current smoking status; most advertising/promotion exposure types were also positively associated with initiation susceptibility among boys and girls. Peer smoking only partially mediated these associations. CONCLUSIONS: Tobacco advertising/promotion exposure was highly prevalent and associated with adolescents' smoking risk in these countries. The comprehensiveness and enforcement of advertising/promotion bans needs to be enhanced.

RESUMO

This article explores cross-sectional associations between depressive symptoms and body mass index (BMI) in women working in schools in the Greater New Orleans area. Self-efficacy for eating and exercise, eating styles, and exercise are examined as potential pathways. This is a secondary data analysis of 743 women who were participating in a workplace wellness randomized controlled trial to address environmental factors influencing eating and exercise behaviors using baseline data prior to the intervention. BMI was the primary outcome examined. Path analysis suggested that increased depressive symptoms were associated with increased BMI in women. Indirect effects of depressive symptoms on BMI were found for increased healthy eating self-efficacy, increased emotional eating, and decreased exercise self-efficacy. The association between greater healthy eating self efficacy and BMI was unexpected, and may indicate a suppressor effect of eating self-efficacy in the relationship between depressive symptoms and BMI in women. The findings suggest the importance of depressive symptoms to BMI in women. Targets for interventions to reduce BMI include targeting depressive symptoms and related sequelae including self-efficacy for exercise, and emotional eating. Further investigation of eating self-efficacy and BMI are recommended with particular attention to both efficacy for health eating and avoidance of unhealthy foods.

RESUMO

BACKGROUND: Incorporating cycling into daily life is one way to increase physical activity. PURPOSE: This study examined the impact of building new bike lanes in New Orleans to determine whether more people were cycling on the street and with the flow of traffic after bike lanes were built. METHODS: Through direct observation of one intervention and two adjacent streets, observers counted cyclists riding on the street and sidewalk, with and against traffic, before and after installation of the lanes. Data were tallied separately for adults, children, males, females, and by race for each location. RESULTS: There was an increase in cyclists on all three streets after the installation of the bike lanes, with the largest increase on the street with the new lane. Additionally, the proportion of riders cycling with traffic increased after the lanes were striped. CONCLUSIONS: Bike lanes can have a positive impact in creating a healthy neighborhood.

RESUMO

BACKGROUND: Beliefs about smoking are important predictors of smoking behavior among adolescents, and adolescents who hold positive beliefs about the benefits of smoking are at an increased risk of smoking initiation. An alarming fact is the rising smoking prevalence in Asian countries, particularly the increasing trend in smoking during adolescence. PURPOSE: This cross-sectional study examined smoking beliefs and behavior among a nationally representative sample of youth in South Korea, Taiwan, and Thailand. METHODS: Descriptive statistics, linear regression, and logistic regression methods were used to analyze data from 13-15-year-old adolescents who participated in the 2005 Global Youth Tobacco Survey (GYTS) in South Korea (N = 4,765) and Thailand (N = 15,420) and the 2007 GYTS in Taiwan (N = 3,955). RESULTS: The rate of ever smoking among youth was similar in all three countries and ranged from 26.7 to 28.0 %. The prevalence of current smoking among youth in Thailand (11.4 %) was nearly double the prevalence in South Korea (6.6 %) and Taiwan (6.5 %). Pro-tobacco advertising exposure, as well as older ages, was a positive and significant predictor of positive beliefs about smoking among youth in all three countries. Additionally, youth who reported increased positive smoking-related beliefs, greater pro-tobacco advertising exposure, and were male were more likely to be current smokers in all three countries. CONCLUSION: Results suggest that greater attention be directed to understanding beliefs and attitudes about smoking among youth. Exploring the relationship between these factors and smoking behavior can provide a strong starting point in the development of effective smoking prevention interventions and tobacco control policies in this region.

RESUMO

The feasibility of working with neighborhood corner stores to increase the availability of fresh fruit and vegetables in low-income neighborhoods in New Orleans was assessed. Household interviews and 24-hour dietary recalls (n = 97), corner store customer intercept interviews (n = 60) and interviews with corner store operators (owners/managers) (n = 12) were conducted in three neighborhoods without supermarkets. Regional produce wholesalers were contacted by phone. Results indicated that the majority of neighborhood residents use supermarkets or super stores as their primary food source. Those who did shop at corner stores typically purchased prepared foods and/or beverages making up nearly one third of their daily energy intake. Most individuals would be likely to purchase fresh fruit and vegetables from the corner stores if these foods were offered. Store operators identified cost, infrastructure and lack of customer demand as major barriers to stocking more fresh produce. Produce wholesalers did not see much business opportunity in supplying fresh produce to neighborhood corner stores on a small scale. Increasing availability of fresh fruit and vegetables in corner stores may be more feasible with the addition of systems changes that provide incentives and make it easier for neighborhood corner stores to stock and sell fresh produce.

RESUMO

Given that alcohol consumption and binge drinking among adolescents in the United States remain prevalent, this study assesses changes in the influence of peer norms-and their interactions with time, gender, and ethnicity-on alcohol consumption. Panel survey interviews of adolescents (N = 1,607) were completed in 9th grade and then again in 12th grade with students from Louisiana. Fixed effects multiple regression assessed the relations between the changes in 2 types of peer norms (i.e., descriptive norms and injunctive norms) and 2 alcohol consumption measures: 30-day alcohol prevalence and binge drinking. Increases in 30-day alcohol prevalence and binge drinking were associated with only descriptive norms. The effects of both types of peer norms intensified over time, and the effects of descriptive norms varied according to gender and ethnicity. Specifically, the influence of descriptive norms was greater on boys than on girls and on Caucasians than on African Americans. Communication interventions that target adolescents in the context of alcohol consumption should consider the temporal variability of peer normative influence and how it varies by gender and ethnicity.

RESUMO

BACKGROUND: Argentina and Uruguay are among the countries with the highest proportion of pregnant women who smoke. The implementation of an effective smoking cessation intervention would have a significant impact on the health of mothers and infants. The "5 A's" (Ask, Advise, Assess, Assist, Arrange) is a strategy consisting of a brief cessation counseling session of 5-15 minutes delivered by a trained provider. The "5 A's" is considered the standard of care worldwide; however, it is under used in Argentina and Uruguay. METHODS: We will conduct a two-arm, parallel cluster randomized controlled trial of an implementation intervention in 20 prenatal care settings in Argentina and Uruguay. Prenatal care settings will be randomly allocated to either an intervention or a control group after a baseline data collection period. Midwives' facilitators in the 10 intervention prenatal clinics (clusters) will be identified and trained to deliver the "5 A's" to pregnant women and will then disseminate and implement the program. The 10 clusters in the control group will continue with their standard in-service activities. The intervention will be tailored by formative research to be readily applicable to local prenatal care services at maternity hospitals and acceptable to local pregnant women and health providers. Our primary hypothesis is that the intervention is feasible in prenatal clinics in Argentina and Uruguay and will increase the frequency of women receiving tobacco use cessation counseling during pregnancy in the intervention clinics compared to the control clinics. Our secondary hypotheses are that the intervention will decrease the frequency of women who smoke by the end of pregnancy, and that the intervention will increase the attitudes and readiness of midwives towards providing counseling to women in the intervention clinics compared to the control clinics.

RESUMO

BACKGROUND: Asset mapping is a commonly used method in public health to identify and describe the resources within a community. However, there is currently a lack of standardization in the methods used for asset mapping, which can make it difficult for users to apply the method and compare results between different studies. In this article, we present a new approach called Asset Mapping Score Analysis (AMSA), which is a framework for collecting and organizing data on community assets. We provide an example of the AMSA method through its application in the evaluation of maternal and child health resources in New Orleans, Louisiana. RESULTS: The AMSA approach consists of five steps and results in a data collection tool that uses a scoring system to quantify the functional and content areas defined by the users. This method is flexible, reproducible, quantitative, inexpensive, and can be adapted to fit the needs of different geographic areas and fields of study. It can also be repeated over time to monitor changes in systems. We conducted a pilot study to examine the participation of local maternal and child health organizations in four functional areas (education, direct services, policy/advocacy, and research) and 22 content areas. CONCLUSIONS: In addition to describing the AMSA method and providing an example of its application, we also discuss the methodological issues involved in using the AMSA approach. These include considerations related to study design, data analysis, and interpreting results. We assess the strengths, limitations, and potential future directions of the AMSA method. Finally, we present the results of our AMSA study on maternal and child health organizations in New Orleans to illustrate the utility of this approach. Our findings suggest that the AMSA method is a valuable tool for understanding and characterizing the assets and resources within a community.

RESUMO

INTRODUCTION: To define the role of focal and reentrant mechanisms underlying nonsustained (NSVT) and sustained ventricular tachycardia (SuVT) induced by programmed stimulation, 3-dimensional cardiac mapping was performed in 8 dogs with heart failure (HF) created by multiple intracoronary microsphere embolizations. METHODS AND RESULTS: Continuous recording from 232 intramural sites throughout the left and right ventricles and the interventricular septum was performed during programmed stimulation in the absence and presence of isoproterenol (Iso, 0.1 µg/kg/min). Sinus beats and the last extrastimuli preceding induced VT conducted with total activation times (TA) of 51 ± 10 and 111 ± 8 milliseconds, respectively, that did not change during Iso infusion (47 ± 4 and 109 ± 5 milliseconds, P = NS). NSVT was induced in 75% of HF dogs; SuVT was induced in 38%. In all cases, initiation and maintenance of SuVT and NSVT arose by a focal mechanism. Compared to NSVT, SuVT had a shorter coupling interval (CI; 150 ± 7 vs 186 ± 16, P < 0.05) and a predilection for certain critical subendocardial initiation sites (that were initiation sites for only 29% of NSVT beats). After 21-30 beats, acceleration of SuVT by a focal mechanism to a CI less than 120 milliseconds led to functional conduction delay (TA increasing from 111 ± 3 to 137 ± 3 milliseconds, P < 0.0001), intramural reentry, and transition to ventricular fibrillation. CONCLUSIONS: Thus, initiation of SuVT in a model of ischemic HF is due to a focal mechanism. However, subsequent acceleration of this focal mechanism can ultimately lead to functional conduction delay and development of intramural reentry.

RESUMO

Prior to the SARS-CoV-2 pandemic, antibiotic resistance was listed as the major global health care priority. Some analyses, including the O'Neill report, have predicted that deaths due to drug-resistant bacterial infections may eclipse the total number of cancer deaths by 2050. Although fungal infections remain in the shadow of public awareness, total attributable annual deaths are similar to, or exceeds, global mortalities due to malaria, tuberculosis or HIV. The impact of fungal infections has been exacerbated by the steady rise of antifungal drug resistant strains and species which reflects the widespread use of antifungals for prophylaxis and therapy, and in the case of azole resistance in Aspergillus, has been linked to the widespread agricultural use of antifungals. This review, based on a workshop hosted by the Medical Research Council and the University of Exeter, illuminates the problem of antifungal resistance and suggests how this growing threat might be mitigated.

RESUMO

This study assessed changes in the influence of social environmental and individual factors-and the interaction of these factors with time-on smoking prevalence for girls. Longitudinal panel surveys of adolescent girls (N = 921 in both 2000 and 2004) from schools in Louisiana were completed in the ninth grade (2000) and then again in the twelfth grade (2004). A fixed effects hierarchical multiple regression model assessed the relation of changes in social environmental and individual factors to smoking prevalence. Increases in smoking prevalence over time among adolescent girls were associated with their perceptions of themselves as overweight and perceiving low risk associated with smoking. Increases in smoking prevalence over time were also associated with having friends who smoked, perceptions of friends' approval of smoking, having family members who smoked, and having monetary discretionary spending. Having friends who smoked was more strongly associated with smoking in the twelfth grade than in the ninth grade. While more black adolescent girls smoked than did white girls in the ninth grade, by the twelfth grade, more white adolescents girls smoked than did black girls. Interventions that target adolescent girls should consider the temporal variability of individual and social environmental factors.
