Cervical cancer screening in the US-Mexico border region: a binational analysis.

Cervical cancer mortality is high along the US-Mexico border. We describe the prevalence of a recent Papanicolaou screening test (Pap) among US and Mexican border women. We analyzed 2006 cross-sectional data from Mexico's National Survey of Health and Nutrition and the US Behavioral Risk Factor Surveillance System. Women aged 20-77 years in 44 US border counties (n = 1,724) and 80 Mexican border municipios (n = 1,454) were studied. We computed weighted proportions for a Pap within the past year by age, education, employment, marital status, health insurance, health status, risk behaviors, and ethnicity and adjusted prevalence ratios (APR) for the US, Mexico, and the region overall. Sixty-five percent (95 %CI 60.3-68.6) of US women and 32 % (95 %CI 28.7-35.2) of Mexican women had a recent Pap. US residence (APR = 2.01, 95 %CI 1.74-2.33), marriage (APR = 1.31, 95 %CI 1.17-1.47) and insurance (APR = 1.38, 95 %CI 1.22-1.56) were positively associated with a Pap test. Among US women, insurance and marriage were associated (APR = 1.21, 95 %CI 1.05-1.38 and 1.33, 95 %CI 1.10-1.61, respectively), and women aged 20-34 years were about 25 % more likely to have received a test than older women. Insurance and marriage were also positively associated with Pap testing among Mexican women (APR = 1.39, 95 %CI 1.17-1.64 and 1.50; 95 %CI 1.23-1.82, respectively), as were lower levels of education (≤8th grade or 9th-12th grade versus some college) (APR = 1.74; 95 %CI 1.21-2.52 and 1.60; 95 %CI 1.03-2.49, respectively). Marriage and insurance were associated with a recent Pap test on both sides of the border. Binational insurance coverage increases and/or cost reductions might bolster testing among unmarried and uninsured women, leading to earlier cervical cancer diagnosis and potentially lower mortality.

Association between depressed mood and perceived weight in middle and high school age students: Texas 2004-2005.

Research exploring the relationship between weight perception and depressed mood among adolescents is limited in the United States. The purpose of this study is to examine the association of perceived versus actual body weight and depressed mood in a representative sample of 8th and 11th grade public school students in Texas. Using data from the 2004-2005 School Physical Activity and Nutrition (SPAN) study, logistic regression analyses were conducted to assess the association of weight perception with depressed mood. Healthy weight students who perceived themselves to be a healthy weight were the reference group for all analyses. A high prevalence of misperception of body weight was observed. Overweight and obese 8th grade girls and boys who perceived themselves to be overweight had increased odds of depressed mood [Girls: OR 1.70 (95% CI: 1.07-2.69), Boys: OR 2.05 (95% CI: 1.16-3.62)]. Healthy weight 8th grade girls who perceived themselves to be overweight had 2.5 times greater odds of depressed mood (OR 2.63, 95% CI: 1.54-4.50). Healthy weight boys who perceived themselves to be underweight had more than twice the odds (OR 2.18, 95% CI: 1.23-3.89) of depressed mood. No weight category was significantly associated with depressed mood in boys or girls in 11th grade. The present study suggests that weight misperceptions are associated with depressed mood in young adolescents. Education about healthy body size is necessary to correct the common weight misperceptions observed. The high prevalence rates of depressed mood suggest a greater need for research into understanding factors that may contribute to depressed mood in adolescents.

Crime rates and sedentary behavior among 4th grade Texas school children.

INTRODUCTION: Although per capita crime has generally fallen over the period which coincides with the obesity epidemic, it has not fallen uniformly across communities. It also has not fallen enough to allay fears on the part of parents. Over the past 30 years, technological changes have made the indoor alternatives to playing outside, where children are more vulnerable to criminal activity, more enjoyable (cable TV, video games, and the internet) and comfortable (the spread of air conditioning to low income neighborhoods). We determined whether indoor sedentary behavior patterns are associated with community crime statistics. 4th graders in the U.S. are typically 9 or 10 years old. METHODS: We used data from the 2004-2005 Texas School Physical Activity and Nutrition (SPAN) survey linked with U.S. Department of Justice, Office of Justice Programs, Bureau of Justice Statistics data for the years 2000 through 2005 and Texas State data on sexual offenders. The probability-based sample included a total of 7,907 children in grade four. Multistage probability sampling weights were used. The dependent variables included were hours of TV watching, video game playing, computer use and total indoor sedentary behavior after school. Incremental Relative Rates were computed for community crime rates including robberies, all violent crimes, murders, assaults, property crimes, rapes, burglaries, larcenies and motor vehicle thefts as well as for sexual offenders living in the neighborhood. The neighborhood refers to the areas where the students at each school live. In the case of sexual offenders, sexual offenders per capita are estimated using the per capita rate in the zip code of the school attended; all other crime statistics are estimated by the crimes per capita in the police department jurisdiction covering the school attended. After controlling for sex, age, and African-American and Hispanic, cross-sectional associations were determined using multivariate Poisson regression. RESULTS: 4th grade boys were more likely to play video games in communities with increased per 100 population rates of larceny and burglary as well as in communities with increased per capita sexual offenders; 4th grade girls were more likely to watch television in communities with increased per capita sexual offenders. While 4th grade girls were more likely to watch TV in communities with increased per capita sex offenders, they were less likely to use computers. Per capita sexual offenders were negatively related to computer use amongst 4th grade girls. CONCLUSION: By combining community crime and cross-sectional individual level data on indoor sedentary behavior, we found that there is an association between community crimes/sex offender rates and certain types of indoor sedentary behavior. The development of technologies in recent decades which makes supervising children easier indoors, where children are much less vulnerable to crime, may be contributing to the epidemic of childhood obesity.

Characteristics of young women who gave birth in the US-Mexico border region, 2005: the Brownsville-Matamoros Sister City Project for Women's Health.

INTRODUCTION: Childbearing during adolescence and young adulthood is associated with adverse effects on health and quality of life. Lowering birth rates among young women is a binational priority in the US-Mexico border region, yet baseline information about birth rates and pregnancy risk is lacking. Increased understanding of the characteristics of young women who give birth in the region will help target high-risk groups for sexual and reproductive health services. METHODS: We examined data on reproductive health characteristics collected in hospitals from 456 women aged 24 years or younger who gave birth from August 21 through November 9, 2005, in Matamoros, Tamaulipas, Mexico, and Cameron County, Texas. We calculated weighted percentages and 95% confidence intervals (CIs) for each characteristic and adjusted odds ratios (AORs) for Matamoros and Cameron County women by using multiple logistic regression techniques. RESULTS: Numbers of births per 1,000 women aged 15 to 19 years and 20 to 24 years were similar in the 2 communities (110.6 and 190.2 in Matamoros and 97.5 and 213.1 in Cameron County, respectively). Overall, 38.5% of women experienced cesarean birth. Matamoros women reported fewer prior pregnancies than did Cameron County women and were less likely to receive early prenatal care but more likely to initiate breastfeeding. Few women smoked before pregnancy, but the prevalence of alcohol use in Cameron County was more than double that of Matamoros. In both communities combined, 34.0% of women used contraception at first sexual intercourse. CONCLUSION: Despite geographic proximity, similar ethnic origin, and comparable birth outcomes, young Mexican and US women showed different health behavior patterns. Findings suggest possible pregnancy prevention and health promotion interventions.

Prenatal HIV testing in the US-Mexico border region, 2005: the Brownsville-Matamoros Sister City Project for Women's Health.

INTRODUCTION: Routine prenatal human immunodeficiency virus (HIV) screening provides a critical opportunity to diagnose HIV infection, begin chronic care, and prevent mother-to-child transmission. However, little is known about the prevalence of prenatal HIV testing in the US-Mexico border region. We explored the correlation between prenatal HIV testing and sociodemographic, health behavior, and health exposure characteristics. METHODS: The study sample consisted of women who delivered live infants in 2005 in hospitals with more than 100 deliveries per year and resided in Matamoros, Tamaulipas, Mexico (n = 489), or Cameron County, Texas (n = 458). We examined univariate and bivariate distributions of HIV testing in Matamoros and Cameron County and quantified the difference in odds of HIV testing by using logistic regression. RESULTS: The prevalence of prenatal HIV testing varied by place of residence--57.6% in Matamoros and 94.8% in Cameron County. Women in Cameron County were significantly more likely than those in Matamoros to be tested. Marital status, education, knowledge of methods to prevent HIV transmission (adult-to-adult), discussion of HIV screening with a health care professional during prenatal care, and previous HIV testing were significantly associated with prenatal HIV testing in Matamoros, although only the latter 2 variables were significant in Cameron County. CONCLUSION: Although national policies in both the United States and Mexico recommend prenatal testing for HIV, a greater proportion of women in Cameron County were tested, compared with women in Matamoros. Efforts between Matamoros and Cameron County to improve HIV testing during pregnancy in the border region should consider correlates for testing in each community.

The effects of acculturation on healthy lifestyle characteristics among Hispanic fourth-grade children in Texas public schools, 2004-2005.

BACKGROUND: Childhood obesity is a national epidemic that disproportionately affects Hispanic children. Evidence suggests that increased acculturation among this population adversely affects diet and other healthy lifestyle characteristics, leading to higher rates of overweight and obesity. Healthy lifestyle characteristics must be understood in order to prevent or decrease overweight and obesity among Hispanic children. METHODS: Using the School Physical Activity and Nutrition (SPAN) study, we examined cross-sectional data on healthy lifestyle characteristics collected in Texas public schools from Hispanic fourth-grade children in 2004-2005. We calculated adjusted odds ratios and associated confidence intervals using multivariate logistic regression analyses to analyze the association between acculturation and healthy lifestyle characteristics among Spanish-speaking Hispanic children compared to English-speaking Hispanic children. RESULTS: Spanish-speaking Hispanic boys consumed more milk and fruit than English-speaking Hispanic boys (milk: adjusted odds ratio [AOR]: 1.7, p = .02; fruit: AOR: 2.5, p = .0001). The likelihood that Spanish-speaking Hispanic boys and girls did not know that there is a relationship between overweight and health problems were 2 times greater (boys: AOR: 1.7, p = .03; girls: AOR: 2.2, p = .006) than their English-speaking Hispanic counterparts. Likelihood of weight loss attempts was greater among Spanish-speaking Hispanic boys than English-speaking Hispanic boys (AOR: 1.9, p = .04). CONCLUSIONS: Results are mixed. Lower levels of acculturation appear to be associated with both positive and negative healthy lifestyle characteristics, depending on sex. These findings have important implications for school health policies and programs and should be distributed to school administrators.

Surveillance of bleeding disorders, Texas, 2007.

BACKGROUND: In 2007, some 1261 patients with hemophilia or other bleeding disorders were seen at federally funded hemophilia treatment centers (HTCs) in Texas. Although HTCs function as sites for passive surveillance of bleeding disorders, annual HTC visit data likely underestimate true prevalence of the disease due to the infrequent nature of healthcare utilization for this population. PURPOSE: The main aim of this study was to compare two alternative methods for estimating prevalence of hemophilia and to describe the challenges associated with making valid prevalence estimates. Each method utilized a separate data source, with the goal of validating one or both of the methods, compared to the gold standard of active case finding. METHODS: Two data sets, one describing treatment of hemophilia in an outpatient setting at HTCs and one describing treatment and care of patients in a hospital inpatient setting, were used to calculate annual prevalence estimates of hemophilia among men in Texas in 2007. The prevalence estimates resulting from each of the two methods were compared to each other and to past estimates based on active surveillance. RESULTS: Calculations based on HTC data resulted in estimated prevalence rates of 8.9 and 2.1/100,000 male population for hemophilia A and B, respectively. Prevalence estimates based on hospital discharge data yielded rates of 12.3 and 2.9/100,000 males for hemophilia A and B, respectively. CONCLUSIONS: Hemophilia is a rare, chronic disease with high treatment costs. Prevalence estimates based on HTC and hospital discharge data were similar to each other as well as to active surveillance prevalence estimates in published literature.

Observable weight distributions and children's individual weight assessment.

Social networks theory suggests obesity is "contagious" within peer groups in that known friends highly influence weight. On the other hand, an alternative model suggests that observable weight distributions affect perception of one's own obesity level. We examine whether the BMI levels of the most obese classmates in the individual student's grade by gender is positively associated with "under-assessment" of obesity and overweight (i.e., independently measured obesity or overweight, but subjective self-assessment of normal weight). The data are the 2004-2005 School Physical Activity and Nutrition III (SPAN), a stratified, multistage probability sample of 4th, 8th, and 11th grade public school children in Texas. We used logistic regression to test whether the gender-specific 85th percentile BMI level within the individual student's grade at their school is positively associated with "under-assessment" of obesity and overweight. The results show that students are much more likely to under-assess their own weight if the gender-specific 85th percentile BMI level is higher in their grade at their school. These data suggest that observable weight distributions play a key role in the obesity epidemic.

Strategies for engaging the private sector in sexual and reproductive health: how effective are they?

The private health sector provides a significant portion of sexual and reproductive health (SRH) services in developing countries. Yet little is known about which strategies for intervening with private providers can improve quality or coverage of services. We conducted a systematic review of the literature through PubMed from 1980 to 2003 to assess the effectiveness of private sector strategies for SRH services in developing countries. The strategies examined were regulating, contracting, financing, franchising, social marketing, training and collaborating. Over 700 studies were examined, though most were descriptive papers, with only 71 meeting our inclusion criteria of having a private sector strategy for one or more SRH services and the measurement of an outcome in the provider or the beneficiary. Nearly all studies (96%) had at least one positive association between SRH and the private sector strategy. About three-quarters of the studies involved training private providers, though combinations of strategies tended to give better results. Maternity services were most commonly addressed (55% of studies), followed by prevention and treatment of sexually transmitted diseases (32%). Using study design to rate the strength of evidence, we found that the evidence about effectiveness of private sector strategies on SRH services is weak. Most studies did not use comparison groups, or they relied on cross-sectional designs. Nearly all studies examined short-term effects, largely measuring changes in providers rather than changes in health status or other effects on beneficiaries. Five studies with more robust designs (randomized controlled trials) demonstrated that contraceptive use could be increased through supporting private providers, and showed cases where the knowledge and practices of private providers could be improved through training, regulation and incentives. Although tools to work with the private sector offer considerable promise, without stronger research designs, key questions regarding their feasibility and impact remain unanswered.
