Parental acculturation and adolescent HPV uptake among Hispanics: Results from the California Health Interview Survey

Background. The Centers for Disease Control and Prevention (CDC), the American Cancer Society (ACS), and the American College of Obstetricians and Gynecologists (ACOG) all recommend the HPV vaccine for girls 11-12. The vaccine has the potential to reduce cervical cancer disparities if it is used by populations that do not participate in screening. Evidence suggests that incidence and mortality are higher among Hispanic women compared to non-Hispanic white women because they do not participate in screening. Past literature has found that acculturation has a mixed effect on cervical cancer screening and immunization. Little is known about whether parental acculturation is associated with adolescent HPV vaccine uptake among Hispanics and the mechanisms through which acculturation may affect vaccine uptake.^ Aims. To examine the association between parental acculturation and adolescent HPV uptake among Hispanics in California and test the structural hypothesis of acculturation by determining if socioeconomic status (SES) and health care access mediate the association between acculturation and HPV vaccine uptake.^ Methods. Cross-sectional data from the 2007 California Health Interview Survey (CHIS) were used for bivariate and multivariate logistic regression analyses. The sample used for analysis included 1,090 Hispanic parents, with a daughter age 11-17, who answered questions about the HPV vaccine. Outcome variable of interest was HPV vaccine uptake (≥1dose). Independent variables of interest were language spoken at home (a proxy variable for acculturation), household income (percent of federal poverty level), education level, and health care access (combined measure of health insurance coverage and usual source of care).^ Results. Parents who spoke only English or English and Spanish in the home were more likely to get the HPV vaccine for their daughter than parents who only spoke Spanish (Odds Ratio [OR]: 0.55, 95% Confidence Interval [CI]: 0.31-0.98). When SES and health care access variables were added to the logistic regression model, the association between language acculturation and HPV vaccine uptake became non-significant (OR: 0.68, 95% CI: 0.35-1.29). Both income and health care access were associated with uptake. Parents with lower income or who did not have insurance and a usual source of care were less likely to have a vaccinated daughter.^ Discussion. Socioeconomic status and health care access have a more proximal effect on HPV vaccine uptake than parental language acculturation among Hispanics in California.^ Conclusion. This study found support for the structural hypothesis of acculturation and suggest that interventions focus on informing low SES parents who lack access to health care about programs that provide free HPV vaccines.^

Shigellosis in Hidalgo County, Texas 2005--2009: A descriptive study

Shigellosis is a communicable disease harbored primarily by humans. The low infective dose, no vaccine availability, and mild or asymptomatic nature of disease has prevented eradication of Shigella in the United States. In addition, the lack of water and sewage infrastructures which normally contribute to the spread of disease in developing countries, for the most part, is a non-issue in the U.S. making surveillance and risk factor identification important prevention and control measures utilized to reduce the incidence rates of Shigellosis.^ The purpose of this study was to describe the Shigellosis disease burden among the Hidalgo County, Texas population during the 2005-2009 study period and compare these findings with national data available. The potential identification and publication of a health disparity in the form of increased Shigellosis rates among Hidalgo County residents when compared to national rates, especially age-specific rates, are intended to generate public health attention and public health action that will address this issue.^ There were 1,007 confirmed Shigellosis cases reported in Hidalgo County, Texas. An overwhelming majority (79%) of the Shigellosis cases during this time frame occurred in children less than ten years of age. Over the age of 10 through the age of 39, females constituted the majority of cases. Age-specific rates for children four years of age and younger were compared to national rates. The rates for Hidalgo County were higher at 9.2 and 1.8 cases for every one case reported nationally in 2005 and 2006, respectively. The total crude rates of Shigellosis were also higher than the rates available from the Foodborne Diseases Active Surveillance Network (FoodNet) of CDC’s Emerging Infections Program from 2005-2009. As a result, compared to the FoodNet surveillance rates, Hidalgo County experienced above average rates of Shigellosis throughout the study period. The majority of cases were identified in young children under the age of ten.^ The information gathered in this analysis could be used to implement and monitor infection control measures such as hand washing education at facilities that tend to the groups identified at higher risk of infection. In addition, the higher burden of disease found in Hidalgo County requires further study to determine if there are factors associated with an increased risk of Shigellosis in this community and other border communities along the U.S.-Mexico border exist.^

Liberation of hope: An ethnographic study of community-based initiatives in Houston, Texas

This is an ethnographic study about the worldview of community-based initiatives in Houston, Texas, and the people who work in them. People who participated in this study recognize that their direct constructive action is at the heart of authentic social change in their minority communities. Through qualitative data analysis, a constellation of relationships and process patterns were found to constitute themselves into the system of the community-based initiative. The predominant patterns identified from the findings in this study are: the pervasiveness of place, the importance of people, unique initiatory patterns, the concrete local sustainability, the ever-present action orientation, the resourceful use of networks and inter-relationships, the significance of church influence, the core sense of spirituality and the essence of hope. These patterns emerged out of the local knowledge, which is acutely sensitive to the elements of history and lived experience, embedded in the distinctive moral and visionary patterns of meaning and expression. Findings from the research reveal that these community-based initiatives are not programs--they are people--people who keep hope alive in their communities and who, by their daily practice, liberate others. ^

A systematic review of the methods used to assess race and racial disparities in uterine fibroid research

Context: Black women are reported to have a higher prevalence of uterine fibroids, and a threefold higher incidence rate and relative risk for clinical uterine fibroid development as compared to women of other races. Uterine fibroid research has reported that black women experience greater uterine fibroid morbidity and disproportionate uterine fibroid disease burden. With increased interest in understanding uterine fibroid development, and race being a critical component of uterine fibroid assessment, it is imperative that the methods used to determine the race of research participants is defined and the operational definition of the use of race as a variable is reported for methodological guidance, and to enable the research community to compare statistical data and replicate studies. ^ Objectives: To systematically review and evaluate the methods used to assess race and racial disparities in uterine fibroid research. ^ Data Sources: Databases searched for this review include: OVID Medline, NML PubMed, Ebscohost Cumulative Index to Nursing and Allied Health Plus with Full Text, and Elsevier Scopus. ^ Review Methods: Articles published in English were retrieved from data sources between January 2011 and March 2011. Broad search terms, uterine fibroids and race, were employed to retrieve a comprehensive list of citations for review screening. The initial database yield included 947 articles, after duplicate extraction 485 articles remained. In addition, 771 bibliographic citations were reviewed to identify additional articles not found through the primary database search, of which 17 new articles were included. In the first screening, 502 titles and abstracts were screened against eligibility questions to determine citations of exclusion and to retrieve full text articles for review. In the second screening, 197 full texted articles were screened against eligibility questions to determine whether or not they met full inclusion/exclusion criteria. ^ Results: 100 articles met inclusion criteria and were used in the results of this systematic review. The evidence suggested that black women have a higher prevalence of uterine fibroids when compared to white women. None of the 14 studies reporting data on prevalence reported an operational definition or conceptual framework for the use of race. There were a limited number of studies reporting on the prevalence of risk factors among racial subgroups. Of the 3 studies, 2 studies reported prevalence of risk factors lower for black women than other races, which was contrary to hypothesis. And, of the three studies reporting on prevalence of risk factors among racial subgroups, none of them reported a conceptual framework for the use of race. ^ Conclusion: In the 100 uterine fibroid studies included in this review over half, 66%, reported a specific objective to assess and recruit study participants based upon their race and/or ethnicity, but most, 51%, failed to report a method of determining the actual race of the participants, and far fewer, 4% (only four South American studies), reported a conceptual framework and/or operational definition of race as a variable. However, most, 95%, of all studies reported race-based health outcomes. The inadequate methodological guidance on the use of race in uterine fibroid studies, purporting to assess race and racial disparities, may be a primary reason that uterine fibroid research continues to report racial disparities, but fails to understand the high prevalence and increased exposures among African-American women. A standardized method of assessing race throughout uterine fibroid research would appear to be helpful in elucidating what race is actually measuring, and the risk of exposures for that measurement. ^

Use of contraception and contraceptive services among U.S. Hispanic women: 2006--2008

This study investigates the association between race/ethnicity and acculturation variables (language preference and nativity) with use of contraception and contraceptive services among Mexican/Mexican American and “other” Hispanic women aged 15-44 when compared to non- Hispanic white women.^ Data was analyzed from the 2006-2008 National Survey of Family Growth. The sample contained 3357 women aged 15-44. Multivariate logistic regression analysis was used to examine the association between race/ethnicity and acculturation variables and contraceptive-related behaviors adjusted for other known covariates. ^ After multivariate analysis, neither nativity nor language preference were significantly associated with contraception use or contraceptive services. Mexican/Mexican American women did not differ in their contraception-related behaviors when compared to non-Hispanic whites. Other Hispanic women, however, were less likely to obtain contraceptive services than non-Hispanic whites (OR=0.67, 95% CI=0.45-1.00). Women aged 30-39 and 40-44 were less likely to obtain contraception and contraceptive services than those aged 15-19. Single women were less likely to use contraception (OR=0.72, 95% CI=0.56-0.92) and contraceptive services (OR=0.69, 95% CI=0.53-0.89) than married/co-habiting women. Women with healthcare coverage were more likely to use contraception and contraceptive services than uninsured women.^ Among Hispanic women of different origin groups, age, marital status, and healthcare coverage were stronger indicators of contraception-related behavior than race/ethnicity, language preference, and nativity. Reproductive health programs that target increased use of contraception and contraceptive services among Hispanic origin groups should specifically target women who are over 30, single, and uninsured.^

Assessing the relationship between obesity and type II diabetes among South Asian Indians in Houston A population based study

Objective: My study aimed at determining the association between obesity and diabetes prevalence in South Asian Indian immigrants in Houston, Texas. To also compare the prevalence odds of diabetes given obesity, using WHO-BMI criteria and recommended Asian ethnic-specific BMI criteria for obesity, as well as using WHO-standard waist circumference criteria and ethnic-specific criteria for abdominal obesity, across gender and age, in this population. ^ Methods: My study was a secondary data analysis based on a cross-sectional study carried out on adult South Asian Indians who attended a local community health fair in Houston, in 2007. They recruited 213 voluntary, eligible, South Asian Indian participants aged between 18 to 79 years. Self reported history of Diabetes was obtained and height, weight, waist and hip circumference were measured. I classified BMI based on WHO-standard and ethnic-specific criteria, according to gender and age groups of 18–35 years, 36–64 years and 65 years and over. Waist circumference was also classified based on WHO-standard NCEP criteria and currently recommended ethnic-specific IDF criteria and analysis was done stratifying by gender and age groups. ^ Results: The prevalence of diabetes in this population was 14.6%, significantly higher in older age groups (25.8%) and males (19.2%). The prevalence of DM was statistically similar in individuals who were overweight/obese compared to those not overweight/obese, however in overweight/obese individuals, there was a statistically significant difference in the prevalence of DM between WHO and ethnic-specific criteria for both BMI and waist circumference. In older adults and in males, ethnic-specific criteria identified significantly more as overweight/obese compared to WHO-standard criteria. ^ Conclusions: Ethnic-specific criteria for both BMI and waist circumference give a better estimate for obesity in this South Asian Indian population. Diabetes is highly prevalent in migrant South Asian Indians even at low BMI or waist circumference levels and significantly more in males and older age groups, hence adequate awareness should be created for early prevention and intervention.^

Cross-sectional study examining the role of acculturation in self-reported hypertension among Mexican Americans in Harris County, Texas

The objective of this secondary analysis was to examine the role of acculturation and self-reported hypertension in a Mexican-American cohort from Harris County, Texas. Specifically, we examined the acculturation measures of language-based Bidimensional Acculturation Scale (BAS), nativity, and length of United States (U.S) residency. Of 6,229 participants aged 40 and older, 38.0% self-reported hypertension at baseline. ^ Multiple logistic regression was used to estimate the prevalence odds ratios (pOR) for the association of each acculturation measure and hypertension while controlling for confounding. When adjusted for age, gender, body mass index, number of comorbidities, and family history of hypertension, U.S.-born participants were 1.37 times more likely to report having hypertension compared to Mexico-born participants (95% CI: 1.21, 1.55). Similarly, immigrants residing in the U.S. for more than 20 years had an adjusted pOR of 1.40 (95% CI: 1.16, 1.70) as compared to immigrants living in the U.S. for less than 10 years. ^ In conclusion, individuals who were born in the U.S. or emigrated to the U.S. over 20 years ago were more likely to report having hypertension compared to individuals born in Mexico or compared to those who emigrated more recently to the U.S. This study will contribute to the literature in demonstrating the need for more initiatives in prevention of cardiovascular disease, specifically hypertension, in the acculturating Mexican American population.^

HPV knowledge, HPV vaccine awareness and initiation among Hispanics: The role of language, information seeking, and information scanning

Background. Among Hispanics, the HPV vaccine has the potential to eliminate disparities in cervical cancer incidence and mortality but only if optimal rates of vaccination are achieved. Media can be an important information source for increasing HPV knowledge and awareness of the vaccine. Very little is known about how media use among Hispanics affects their HPV knowledge and vaccine awareness. Even less is known about what differences exist in media use and information processing among English- and Spanish-speaking Hispanics.^ Aims. Examine the relationships between three health communication variables (media exposure, HPV-specific information scanning and seeking) and three HPV outcomes (knowledge, vaccine awareness and initiation) among English- and Spanish-speaking Hispanics.^ Methods. Cross-sectional data from a survey administered to Hispanic mothers in Dallas, Texas was used for univariate and multivariate logistic regression analyses. Sample used for analysis included 288 mothers of females aged 8-22 recruited from clinics and community events. Dependent variables of interest were HPV knowledge, HPV vaccine awareness and initiation. Independent variables were media exposure, HPV-specific information scanning and seeking. Language was tested as an effect modifier on the relationship between health communication variables and HPV outcomes.^ Results. English-speaking mothers reported more media exposure, HPV-specific information scanning and seeking than Spanish-speakers. Scanning for HPV information was associated with more HPV knowledge (OR = 4.26, 95% CI = 2.41 - 7.51), vaccine awareness (OR = 10.01, 95% CI = 5.43 - 18.47) and vaccine initiation (OR = 2.54, 95% CI = 1.09 - 5.91). Seeking HPV-specific information was associated with more knowledge (OR = 2.27, 95% CI = 1.23 - 4.16), awareness (OR = 6.60, 95% CI = 2.74 - 15.91) and initiation (OR = 4.93, 95% CI = 2.64 - 9.20). Language moderated the effect of information scanning and seeking on vaccine awareness.^ Discussion. Differences in information scanning and seeking behaviors among Hispanic subgroups have the potential to lead to disparities in vaccine awareness.^ Conclusion. Findings from this study underscore health communication differences among Hispanics and emphasize the need to target Spanish language media as well as English language media aimed at Hispanics to improve knowledge and awareness.^

The illness experiences of African Americans residing in an inner city community, Houston, Texas

This dissertation documents health and illness in the context of daily life circumstances and structural conditions faced by African American families living in Clover Heights (pseudonym), an inner city public housing project in the Third Ward, Houston, Texas. Drawing from Kleinman's (1980) model of culturally defined health care systems and using the holistic-content approach to narrative analysis (Lieblich, Tuval- Mashiach, & Zilber, 1998) the purpose of this research was to explore the ways in which social and health policy, economic mobility, the inner city environment, and cultural beliefs intertwined with African American families' health related ideas, behaviors, and practices. I recruited six families using a convenience sampling method (Schensul, Schensul, & LeCompte, 1999) and followed them for fourteen months (2010–2011). Family was defined as a household unit, or those living in the same residence, short or long-term. Single, African American women ranging in age from 29–80 years headed all families. All but one family included children or grandchildren 18 years of age and younger, or children or other relative 18 years of age and older. I also recruited six residents with who I became acquainted over the course of the project. I collected data using traditional ethnographic methods including participant-observation, archive review, field notes, mapping, free-listing, in-depth interviews, and life history interviews. ^ Doing ethnography afforded the families who participated in this project the freedom to construct their own experiences of health and illness. My role centered on listening to, learning from, and interpreting participants' narratives, exploring similarities and differences within and across families' experiences. As the research progressed, a pattern concerning diagnosis and pharmacotherapy for children's behavioral and emotional problems, particularly attention-deficit hyperactivity disorder (ADHD) and pediatric bipolar disorder (PBD), emerged from my formal interactions with participants and my informal interactions with residents. The findings presented in this dissertation document this pattern, focusing on how mothers and families interpreted, organized, and ascribed meaning to their experiences of ADHD and PBD. ^ In the first manuscript presented here, I documented three mothers' narrative constructions of a child's diagnosis with and pharmacotherapy for ADHD or PBD. Using Gergen's (1997) relational perspective I argued that mothers' knowledge and experiences of ADHD and PBD were not individually constructed, but were linguistically and discursively constituted through various social interactions and relationships, including family, spirituality and faith, community norms, and expert systems of knowledge. Mothers' narratives revealed the complexity of children's behavioral and emotional problems, the daily trials of living through these problems, how they coped with adversity and developed survival strategies, and how they interacted with various institutional authorities involved in evaluating, diagnosing, and encouraging pharmaceutical intervention for children's behavior. The findings highlight the ways in which mothers' social interactions and relationships introduced a scientific language and discourse for explaining children's behavior as mental illness, the discordances between expert systems of knowledge and mothers' understandings, and how discordances reflected mothers' ‘microsources of power’ for producing their own stories and experiences. ^ In the second manuscript presented here, I documented the ways in which structural factors, including gender, race/ethnicity, and socioeconomic status, coupled with a unique cultural and social standpoint (Collins, 1990/2009) influenced the strategies this group of African American mothers employed to understand and respond to ADHD or PBD. The most salient themes related to mother-child relationships coalesced around mothers' beliefs about the etiology of ADHD and PBD, ‘conceptualizing responsibility,’ and ‘protection-survival.’ The findings suggest that even though mothers' strategies varied, they were in pursuit of a common goal. Mothers' challenged the status quo, addressing children's behavioral and emotional problems in the ways that made the most sense to them, specifically protecting their children from further marginalization in society more so than believing these were the best options for their children.^

A cross-sectional analysis of the association between polycyclic aromatic hydrocarbons and diesel particulate matter exposures and hypertension among individuals of Mexican origin residing in Houston, TX

Background. Research has shown that elevations of only 10 mmHg diastolic blood pressure (BP) and 5 mmHg systolic BP are associated with substantial (as large as 50%) increases in risks for cardiovascular disease, a leading cause of death, worldwide. Epidemiological studies have found that particulate matter (PM) increases blood pressure (BP) and many biological mechanisms which may suggest that the organic matter of PM contributes to the increase in BP. To understand components of PM which may contribute to the increase in BP, this study focuses on diesel particulate matter (DPM) and polycyclic aromatic hydrocarbons (PAHs). To our knowledge, there have been only four epidemiological studies on BP and DPM, and no epidemiological studies on BP and PAHs. ^ Objective. Our objective was to evaluate the association between prevalent hypertension and two ambient exposures: DPM and PAHs amongst the Mano a Mano cohort. ^ Methods. The Mano a Mano cohort which was established by the M.D. Anderson Cancer Center in 2001, is comprised of individuals of Mexican origin residing in Houston, TX. Using geographical information systems, we linked modeled annual estimates of PAHs and DPM at the census track level from the U.S. Environmental Protection Agency's National-Scale Air Toxics Assessment to residential addresses of cohort members. Mixed-effects logistic regression models were applied to determine associations between DPM and PAHs and hypertension while adjusting for confounders. ^ Results. Ambient levels of DPM, categorized into quartiles, were not statistically associated with hypertension and did not indicate a dose response relationship. Ambient levels of PAHs, categorized into quartiles, were not associated with hypertension, but did indicate a dose response relationship in multiple models (for example: Q2: OR = 0.98; 95% CI, 0.73–1.31, Q3: OR = 1.08; 95% CI, 0.82–1.41, Q4: OR = 1.26; 95% CI, 0.94–1.70). ^ Conclusion. This is the first assessment to analyze the relationship between ambient levels of PAHs and hypertension and it is amongst a few studies investigating the association between ambient levels of DPM and hypertension. Future analyses are warranted to explore the effects DPM and PAHs using different categorizations in order to clarify their relationships with hypertension.^

Globesity: Food marketing to children in Asia-Pacific A systematic review

Food advertising and promotion to children has been identified as one possible contributing factor to the childhood obesity pandemic. Food marketing to children in "western" society consists mainly of foods that are high in fat, sugar and salt (HFSS), such as pre-sugared breakfast cereals; sugar sweetened beverages (SSBs); confectionary; savory snacks; and fast food. Of these heavily marketed items consumption of, SSBs, savory snacks and fast foods have been found to contribute to the childhood obesity pandemic. A systematic review was conducted to determine what types of products are being promoted and what types of techniques food marketers are using to promote these foods throughout the Asia-Pacific region. The review of current literature, while not abundant, clearly showed marketing styles and content similar to those in western countries were being employed in the Asia-Pacific. Advertisements in this geographic region often took on a local flair to make them more identifiable to children and adolescents in their respective regions and countries, due to the numerous cultural and traditional differences. Children in these developing parts of the world may be just as, if not more, susceptible to these advertising techniques than their counterparts in the west.^

Socioeconomic disparities in thyroid cancer incidence within the Surveillance, Epidemiology, and End Results (SEER) registry, 1980--2008

Background. In the past two decades, the incidence of thyroid cancer in the United States (US) has been increasing. There has been debate on whether the increase is real or an artifact of improved diagnostic scrutiny. Methods. We linked SEER9 database with 2000 US Census to obtain county-level SES (Socioeconomic Status) and compared thyroid cancer incidence trends between high and low SES counties. Joinpoint analysis was used to assess the thyroid cancer incidence trends. Annual Percentage Changes (APCs) were calculated to evaluate incidence trends. Results . The thyroid cancer incidence in high SES counties increased moderately (APC1=+2.5*, *P<0.05) before late 1990s and dramatically increased (APC2=+6.3*) after late 1990s, whereas incidence in low SES counties increased moderately (APC=+3.5*) during the entire time period (1980–2008). For smaller tumors (≤4cm), the APCs in high and low SES counties are similar to each other before late 1990s, but the incidence in high SES counties increased dramatically after late 1990s while that in low SES counties continued at a moderate increase. For large tumors (>4cm), the incidence trends in high SES counties are similar to those of low SES counties, which had a steady moderate increase. Conclusion. Our findings indicate that enhanced detection likely contributed to the increased thyroid cancer incidence in the past decades but cannot fully explain the increase, suggesting that a true increase also exists. Efforts should be made on identifying the cause of this observed increased incidence as well as more refined/selected screening and prevention measures.^

Association of processed red meat and prostate cancer stage in Mexican-Americans: A population based case-control study

Objective: The objective of this study is to investigate the association between processed and unprocessed red meat consumption and prostate cancer (PCa) stage in a homogenous Mexican-American population. Methods: This population-based case-control study had a total of 582 participants (287 cases with histologically confirmed adenocarcinoma of the prostate gland and 295 age and ethnicity-matched controls) that were all residing in the Southeast region of Texas from 1998 to 2006. All questionnaire information was collected using a validated data collection instrument. Statistical Analysis: Descriptive analyses included Student's t-test and Pearson's Chi-square tests. Odds ratios and 95% confidence intervals were calculated to quantify the association between nutritional factors and PCa stage. A multivariable model was used for unconditional logistic regression. Results: After adjusting for relevant covariates, those who consume high amounts of processed red meat have a non-significant increased odds of being diagnosed with localized PCa (OR = 1.60 95% CI: 0.85 - 3.03) and total PCa (OR = 1.43 95% CI: 0.81 - 2.52) but not for advanced PCa (OR = 0.91 95% CI: 1.37 - 2.23). Interestingly, high consumption of carbohydrates shows a significant reduction in the odds of being diagnosed with total PCa and advanced PCa (OR = 0.43 95% CI: 0.24 - 0.77; OR = 0.27 95% CI: 0.10 - 0.71, respectively). However, consuming high amounts of energy from protein and fat was shown to increase the odds of being diagnosed with advanced PCa (OR = 4.62 95% CI: 1.69 - 12.59; OR = 2.61 95% CI: 1.04 - 6.58, respectively). Conclusion: Mexican-Americans who consume high amounts of energy from protein and fat had increased odds of being diagnosed with advanced PCa, while high amounts of carbohydrates reduced the odds of being diagnosed with total and advanced PCa.^

Factors associated with contraception use among postpartum or parenting Latina adolescents: A systematic review

Despite advances in effective and long-acting contraceptive methods and the introduction into health care that an initial unplanned pregnancy allows, repeat unplanned pregnancy continues to affect Hispanic adolescents at a rate higher than that of non-Hispanic whites. The current study was undertaken to identify and categorize factors associated with uptake of long acting contraception (implant or intrauterine devices) or consistent use of highly effective methods (injectable DMPA, ring, patch, or pills), among Hispanic/Latina teens who have previously given birth. ^ I searched Ovid Medline, Pubmed, CINAHL, PsychINFO, POPLINE and Scopus, and reference lists for studies in English, ≥1980, of original data from the United States on factors related to initiation, maintenance, or discontinuation of contraceptive methods in postpartum or parenting adolescent females. I then identified articles that specified the inclusion of Hispanics/Latinas in the study population and either reported findings specific to race/ethnicity or used race/ethnicity as an independent variable in analyses of contributing factors. I then extracted data for each study and categorized independent variables as predisposing, enabling, or reinforcing following the PRECEDE model.1 Factors found to be associated with contraception use or non-use were combined to create a logic model of risk. ^ Of 9 eligible studies, one solely addressed initiation; one, initiation and maintenance; two, initiation and discontinuation; three, maintenance; and two, maintenance and discontinuation. There was some overlap in the studies' assessments of maintenance and discontinuation and the author(s) often did not distinguish between the two. Nearly all (k=7) were prospective observational studies with convenience samples and bivariate analyses (k=6). One study was initially a quasi-experimental design but became a prospective cohort due to extremely high attrition. Sociodemographic characteristics and predisposing factors were studied frequently, as were reinforcing factors; enabling factors were discussed infrequently and only in studies involving focus groups or interviews. Due to a paucity of research, a consensus of factors found consistently to influence the contraception behavior of postpartum Latina teens could not be established for the overall population nor for cultural subgroups. Future research is needed that focuses on postpartum/parenting Latina teens, with subgroup identification and differentiation, to determine the prevalent and pertinent predisposing, enabling, and reinforcing factors related to effective contraception initiation and maintenance.^

Risk factors for metabolic syndrome among overweight and obese Hispanic children attending a pediatric clinic in New Braunfels, Texas

Childhood obesity is a persistent problem in the U.S., especially among Hispanics. Health complications like hypertension, type II diabetes, and metabolic syndrome (Met-S) are being seen at younger ages, and current screening procedures may be inadequate. This study sought to describe the risk factors for Met-S present in a sample of 106 overweight and obese Hispanic children, aged 5-14 years, participating in Nutrition and Exercise Start Today (NEST), a randomized weight management intervention trial at a rural health clinic in New Braunfels, Texas; and to determine associations between these factors and other clinical and socio-demographic characteristics linked to obesity. Baseline data was analyzed for the prevalence of large waist circumference (WC), elevated blood pressure (BP), high fasting serum glucose and serum triglycerides (TG), and low serum HDL cholesterol, in relationship with selected sample characteristics. Main findings included high baseline prevalence rates of large WC (77%), reduced HDL (57%), and elevated BP (30%). WC was significantly associated with BMI percentile and the serum liver function test alanine aminotransferase (ALT) by Fisher's exact test (p<0.001 and p=0.032, respectively), while there were significant relationships between HDL and both female gender and ALT. BMI percentile and ALT were associated with all sets of Met-S diagnostic criteria examined. BMI percentile also had a strong association (p=0.005) with total number of Met-S risk factors, while ALT had a weaker association (p=0.093). WC is a low-cost, simple measure whose use may improve clinic surveillance for childhood obesity and complications like Met-S. WC, BP, HDL and ALT may be used as part of targeted screening for obesity complications like Met-S, particularly in situations where resources are limited.^
