Prevalence and clinical characteristics of urinary incontinence in elderly individuals of a low income

To estimate the prevalence of urinary incontinence (UI) in elderly individuals of low income assisted by the primary health care system in Sao Paulo, Brazil. In this community-based, observational, cross-sectional study, participants assisted by the health family program in Sao Paulo, Brazil, were sampled and interviewed face to face by questionnaire. Participants (n = 388) were selected from the collaborative program developed by the 10/66 Dementia Research Group, an International Network of investigators. Demographics, health history and a detailed assessment of UI and urinary symptoms were obtained. Prevalence of UI was calculated. Other variables included age, body mass index (BMI), duration of incontinence and characteristics of the symptoms. The association between UI and the variables was estimated using the Kruskal-Wallis test, Chi-squared test and Fisher test (depending on normality of the distribution and expected frequencies). Prevalence of UI was 38.4%. UI was more common in women than in men (50% vs. 18.3%, p < 0.001). Diabetes, obesity and hypertension were associated with UI. Almost 36.2% of the cases were of mixed incontinence, 26.8% of urge incontinence and 24.2% of stress incontinence. Men were more likely to have urge-incontinence, while women were more likely to have mixed incontinence (p = 0.001). UI is prevalent in the elderly of low income living in Sao Paulo and rates are higher than most previous studies. Chronic conditions such as hypertension, diabetes and obesity were associated with UI. (C) 2011 Elsevier Ireland Ltd. All rights reserved.

Nutritional transition of school children from low income families of a northeastern urban area, Brazil

Background: Evaluating child growth is, in practice, performed by measuring the development of a child's weight, height, and body composition in comparison to averages observed among a reference population. Objective: To describe the nutritional status of children of low income families who live in urban region in northeastern Brazil. Methods: This study is a population case series with a transversal and observational design. The study population consisted of 257 children, aged 5 to 10 years, who were enrolled in a public school to children of low income families. We used the cutoff point for short stature of -2 Z scores for age, and underweight, overweight, and obese were classified as the 5th, 85th, and 95th percentiles, respectively, of the body mass index (BMI) for age, with both classifications in accordance with the Center for Disease Control and Prevention (CDC 2000). Comparisons by gender were performed for the measures of the central tendency and the frequency of diagnoses, in addition to the tendency of the evolution of BMI by age. Results: The prevalence of short stature was 3.5% (95% CI: 1.9-6.5). In the evaluation of BMI for age, the prevalences found for underweight, overweight, and obese were 5.8% (95% CI: 3.6-9.4), 4.7% (95% CI: 2.7-8.0), and 2.3% (95% CI: 1.1-5.0), respectively. We found a significant trend in the reduction of BMI with the increase in age. Conclusions: According to CDC references, the prevalences of underweight and short stature were higher than expected and for the overweight and obesity were lower than expected, indicating that the nutritional transition had still not reached, as commonly is described, these low income children from the urban outskirts of the Northeast region.

The shock index and the simplified PESI for identification of low-risk patients with acute pulmonary embolism

We compared the test characteristics of the shock index (SI) and the simplified pulmonary embolism severity index (sPESI) for predicting 30-day outcomes in a cohort of 1,206 patients with objectively confirmed pulmonary embolism (PE). The primary outcome of the study was all-cause mortality. The secondary outcome was nonfatal symptomatic recurrent venous thromboembolism (VTE) or nonfatal major bleeding. Overall, 119 (9.9%) out of 1,206 patients died (95% CI 8.2-11.5%) during the first month of follow-up. The sPESI classified fewer patients as low-risk (369 (31%) out of 1,206 patients, 95% CI 28-33%) compared to the SI (1,024 (85%) out of 1,206 patients, 95% CI 83-87%) (p<0.001). Low-risk patients based on the sPESI had a lower 30-day mortality than those based on the SI (1.6% (95% CI 0.3-2.9%) versus 8.3% (95% CI 6.6-10.0%)), while the 30-day rate of nonfatal recurrent VTE or major bleeding was similar (2.2% (95%CI 0.7-3.6%) versus 3.3% (95%CI 2.2-4.4%)). The net reclassification improvement with the sPESI was 13.4% (p = 0.07). The integrated discrimination improvement was estimated as 1.8% (p<0.001). The sPESI quantified the prognosis of patients with PE better than the SI.

Commentary on "A Needs Assessment Examining Low-Income Fathers’ Barriers to Participation in Parenting Programs"

The article provides insight on issues serving as barriers to low-income fathers' involvement with their children and with parenting programs.

Low-Income Fathers’ Barriers to Participation in Family and Parenting Programs

This exploratory study used semi-structured focus groups to examine: 1) where and from whom fathers obtain information about parenting; 2) the types of parenting services men are aware of, and their attitudes about participating in such services; and 3) fathers’ perceived norms about the acceptability and utility of various parenting practices. Low-income men (N = 17) were recruited from a human services agency in Detroit, Michigan. Four major themes emerged. First was the need for male-focused community resources for fathers. Second was that men were aware of and used positive disciplinary strategies. Third was emphasis on fathers’ positive and effective communication, with male children in particular. Finally, men suggested that constructive and concrete activities, such as engaging with children in activities or mentorship programs with other adult men in the community, were preferable to traditional parenting class such as those offered through Child Protective Services.

Low-Income Developing Countries and WTO Litigation: Why Wake Up the Sleeping Dog?

The World Trade Organization (WTO) is one of the most judicialized dispute settlement systems in international politics. While a general appreciation has developed that the system has worked quite well, research has not paid sufficient attention to the weakest actors in the system. This paper addresses the puzzle of missing cases of least-developed countries initiating WTO disputes settlement procedures. It challenges the existing literature on developing countries in WTO dispute settlement which predominantly focuses on legal capacity and economic interests. The paper provides an argument that the small universe of ‘actionable cases’, the option of free riding and the assessment of the perceived opportunity costs related to other foreign policy priorities better explain the absence of cases. In addition (and somewhat counterintuitively), we argue that the absence of cases is not necessarily bad news and shows how the weakest actors can use the dispute settlement system in a ‘lighter version’ or in indirect ways. The argument is empirically assessed by conducting a case study on four West African cotton-producing countries (C4) and their involvement in dispute settlement.

Age-specific and sex-specific weight gain norms to monitor antiretroviral therapy in children in low-income and middle-income countries.

BACKGROUND Viral load and CD4% are often not available in resource-limited settings for monitoring children's responses to antiretroviral therapy (ART). We aimed to construct normative curves for weight gain at 6, 12, 18, and 24 months following initiation of ART in children, and to assess the association between poor weight gain and subsequent responses to ART. DESIGN Analysis of data from HIV-infected children younger than 10 years old from African and Asian clinics participating in the International epidemiologic Databases to Evaluate AIDS. METHODS The generalized additive model for location, scale, and shape was used to construct normative percentile curves for weight gain at 6, 12, 18, and 24 months following ART initiation. Cox proportional models were used to assess the association between lower percentiles (< 50th) of weight gain distribution at the different time points and subsequent death, virological suppression, and virological failure. RESULTS Among 7173 children from five regions of the world, 45% were underweight at baseline. Weight gain below the 50th percentile at 6, 12, 18, and 24 months of ART was associated with increased risk of death, independent of baseline characteristics. Poor weight gain was not associated with increased hazards of virological suppression or virological failure. CONCLUSION Monitoring weight gain on ART using age-specific and sex-specific normative curves specifically developed for HIV-infected children on ART is a simple, rapid, sustainable tool that can aid in the identification of children who are at increased risk of death in the first year of ART.

Characterization of diabetes risk factors of elementary school children in low income areas of San Antonio, Texas

The number of children developing type-2 diabetes mellitus (T2DM) is increasing globally, especially in Western countries. Previous studies have indicated that low socioeconomic status (SES) is a contributing factor to diabetes. This study of children examined the relationship of socioeconomic status and two physiological measures that are risk factors for diabetes: the level of fasting capillary glucose (FCG) and hyperglycemia, in which there is an elevated amount of glucose in the blood. This study utilized data from the study entitled Bienester: A School-Based Diabetes Mellitus Prevention Program. The sample was 1,426 fourth grade students from 27 San Antonio Independent School District elementary schools. The dependent variable was FCG and the independent variable was the median family income associated with the student's zip code based on Census information. Other variables included body mass index, gender, and ethnicity. The statistical results showed no relationship between FCG, continuously defined, and income. In addition, there was no relationship between hyperglycemia and income. Furthermore, there was no relationship of FCG with BMI, gender, or ethnicity. Income measured at the zip code level is likely too aggregate and distal an influence to demonstrate an impact on FCG. Research should continue to examine risk factors associated with the onset of T2DM.^

Formative evaluation of a parental involvement program for obesity prevention with low-income elementary school children

This study addresses the responses to a postcard campaign with health messages targeting the parents of children in a sample of low-income elementary schools and assesses the feasibility and areas of possible improvements in such a project. The campaign was implemented in Spring 2009 with 4 th grade students (n=1070) in fifteen economically disadvantaged elementary schools in Travis County, Texas. Postcards were sent home with children, and parents filled out a feedback card that the children returned to school. Response data, in the form of self-administered feedback cards (n=2665) and one-on-one teacher interviews (n=8), were qualitatively analyzed using NVivo 8 software. Postcard reception and points of improvement were then identified from the significant themes that emerged including health, cessation or reduction of unhealthy behaviors, motivation, family, and the comprehension of abstract health concepts. ^ Responses to the postcard campaign were almost completely positive, with less than 1% of responses reporting some sort of dislike, and many parents reported a modification of their behavior. However, possible improvements that could be made to the campaign are: increased focus of the postcards on the parents as the target population, increased information about serving size, greater emphasis on the link between obesity and health, alteration of certain skin tones used in the graphical depiction of people on the cards, and smaller but more frequent incentives to return the feedback cards for the students. The program appears to be an effective method of communicating health messages to the parents of 4th grade children.^

Examining seasonal variations in physical activity among low-income Hispanic walk-trail users living in the Cameron Park Colonia

This study examines variations in physical activity by season, and within seasons by age and gender among park users living in the Cameron Park Colonia, a low-income Hispanic community along the Texas-Mexico border. This is the first study of its kind to evaluate seasonal variations by physical activity among a Hispanic population. We hypothesized that (1) there are no differences in overall physical activity by season; (2) youth engage in more sport-related physical activity compared to adults, (3) males engage in more physical activity than females, and (4) there are differences in physical activity between walk-trail users compared to non walk-trail users in the park.^ Physical activity behavioral data was collected (males n=2,093; females n=1,014) at two time periods (winter 2007; summer 2007) via direct observations and assessed park use, walking trail use, and physical activity (moderate-to-vigorous physical activity (MVPA) by seasons. Frequencies for physical activities were calculated for gender, age groups, and season. Separate Pearson's chi-square analyses were used to address variations in physical activity, age, gender, intensity level of physical activity by season, between walk-trails users and non walk-trail users.^ People visiting the park engaged in more sedentary behavior in winter than summer and a higher percentage engaged in MVPA in the summer than winter (p<.05). More females engaged in light activity compared to males (p<.05). Walk-trail users consisted mostly of females and engaged in more light activity than non walk-trail users (p<.05) who participated in more MVPA.^ Increasing access to parks and walk-trails may be an intervention strategy to increase physical activity among Hispanics. More research is needed to assess promoting trail use and determining long-term effects on physical activity among minority/ethnic groups at greater risk of a sedentary lifestyle and reasons for trail use and non-use. Future studies should focus on the types of activities Hispanics engage in at different parks particularly between men and women. As a result of this study city officials and planners may use this information to build and design parks that cater to the types of activities that Hispanics engage in and may use to meet physical activity guidelines.^

The use of social media to communicate child health information to low-income parents: A formative study

The Internet, and specifically web 2.0 social media applications, offers an innovative method for communicating child health information to low-income parents. The main objective of this study was to use qualitative data to determine the value of using social media to reach low-income parents with child health information. A qualitative formative evaluation employing focus groups was used to determine the value of using social media for dissemination of child health information. Inclusion criteria included: (1) a parent with a child that attends a school in a designated Central Texas school district; and (2) English-speaking. The students who attend these schools are generally economically disadvantaged and are predominately Hispanic. The classic analysis strategy was used for data analysis. Focus group participants (n=19) were female (95%); White (53%), Hispanic (42%) or African American (5%); and received government assistance (63%). Most had access to the Internet (74%) and were likely to have low health literacy (53%). The most preferred source of child health information was the family pediatrician or general practitioner. Many participants were familiar with social media applications and had profiles on popular social networking sites, but used them infrequently. Objections to social media sites as sources of child health information included lack of credibility and parent time. Social media has excellent potential for reaching low-income parents when used as part of a multi-channel communication campaign. Further research should focus on the most effective type and format of messages that can promote behavior change in this population, such as story-telling. ^

Associations between teacher support and students' fruit and vegetable consumption in low-income elementary schools in central Texas

Background. Similar to parent support in the home environment, teacher support at school may positively influence children's fruit and vegetable (FV) consumption. This study assessed the relationship between teacher support for FV consumption and the FV intake of 4th and 5th grade students in low-income elementary schools in central Texas. Methods. A secondary analysis was performed on baseline data collected from 496 parent-child dyads during the Marathon Kids study carried out by the Michael & Susan Dell Center for Healthy Living at the University of Texas School of Public Health. A hierarchical linear regression analysis adjusting for key demographic variables, parent support, and home FV availability was conducted. In addition, separate linear regression models stratified by quartiles of home FV availability were conducted to assess the relationship between teacher support and FV intake by level of home FV availability. Results. Teacher support was not significantly related to students' FV intake (p = .44). However, the interaction of teacher support and home FV availability was positively associated with students' FV consumption (p < .05). For students in the lowest quartile of home FV availability, teacher support accounted for approximately 6% of the FV intake variance (p = .02). For higher levels of FV availability, teacher support and FV intake were not related. Conclusions. For lower income elementary school-aged children with low FV availability at home, greater teacher support may lead to modest increases in FV consumption.^

Let their voices be heard: Understanding the barriers to seeking early prenatal care for low-income non-Hispanic Black women

Background: Receipt of early prenatal care, care during the first three months of pregnancy, is the standard in the United States. Sixty percent of non-Hispanic Black women who had a live birth in the Sunnyside community of Houston did not obtain early prenatal care in 2009. ^ This study's aims were to: 1) Describe the barriers to obtaining early prenatal care in non-Hispanic Black women who live in the Sunnyside community of Houston; and, 2) Describe the actions that could encourage non-Hispanic Black women who live in the Sunnyside Community to obtain early prenatal care. The goal was to provide information to organizations that promote early prenatal care use in non-Hispanic Black women in Harris County that may aid in developing interventions. ^ Methods: The Participatory Learning for Action rapid assessment qualitative method was used in a group setting to answer the research questions on behalf of women in the community. Women who participated in the group sessions also participated in an in-depth interview. Key informants who work in the community with pregnant women, or promote the use of prenatal care services, were also interviewed. An inductive analysis of the data was conducted to identify common themes that address the study's aims. ^ Results: Aim 1: Group participants identified fear of the reaction from family and/or the baby's daddy and shame, not having insurance or money, and lack of knowledge of the pregnancy and resources as the top three barriers to early prenatal care for women in the community. Aim 2: Group participants stated that to help women to overcome these barriers, communication, awareness and support; help, resources and services; and information and early education are needed. Participant in-depth interviewees echoed the themes of fear of the reaction from family and/or the baby's daddy and not knowing of the pregnancy. Key informants mentioned these themes as well, though not at the same priority level. Participants and key informants also mentioned similar themes for helping women to overcome barriers to early prenatal care. ^ Conclusion: A comprehensive approach is needed to improve early prenatal care use in the Sunnyside community. Education efforts must include all members of the community, young and old, to promote support for pregnant women. Community members must be a part of the process for developing education campaigns. Engaging the community builds a relationship with organizations that serve the community, which may promote use of the organizations' services, and build trust with the community. All efforts must be ongoing so that women and men of all ages in the community understand the importance of prenatal care and support women obtaining care early in the pregnancy.^
