Proximal deep vein thrombosis among hospitalised medical and obstetric patients in Rwandan university teaching hospitals: prevalence and associated risk factors: a cross-sectional study.

Objectives: To determine the prevalence of proximal deep vein thrombosis (DVT) by ultrasound scanning, as well as associated clinical features and known risk factors, among medical and obstetrics-gynaecology inpatients in two Rwandan tertiary hospitals.

Design: Cross-sectional study.

Settings: Rwanda teaching hospitals: Kigali and Butare University Teaching Hospitals.

List and text recall differ in their predictors: replication over samples and time.

This study tested the hypothesis that latent list and text recall invoke somewhat different processes. A bivariate outcome path model of latent list and text recall evaluated the effects of age, latent speed, working memory, and vocabulary as their predictors. Independent of age, working memory reliably predicted both recall variables, whereas speed reliably predicted list recall only.

Overweight among low-income Texas preschoolers aged 2 to 4 years.

Objective: Determine child/maternal factors associated with overweight among 2- to 4-year-olds enrolled in the Texas Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

Design: Matched child and maternal data collected by self-report of the mother during WIC certification. These data were extracted from existing statewide WIC databases and merged.

Prevalence and risk factors for adult paternity among adolescent females ages 14 through 16 years.

To investigate sociodemographic factors associated with adolescent females ages 14-16 years having children fathered by males age 20 years or older and identify differences in correlates across rural, urban, and border areas. The method section was a cross-sectional study using Texas birth record data. From 2000 through 2004, there were 29,186 births to adolescent females aged 14-16 years with valid paternal age.

Physical activity participation by parental language use in 4th, 8th, and 11th grade students in Texas, USA.

Research on physical activity (PA) by level of acculturation in Hispanic children is limited and findings have been mixed. We examined PA participation by primary language used with parents in a representative sample of 4th, 8th, and 11th grade Texas public school students. Mixed-effects regression models were conducted using cross-sectional data from the 2004-2005 School Physical Activity and Nutrition Study (n = 22,049).

Teen pregnancy in Texas: 2005 to 2015.

Objectives: Texas birth records and population projections were used to simulate pregnancy rates among women ages 15-19 years from 2005 to 2015.

Methods: Monte Carlo simulation based on historical rates of natural increase, contraceptive failure and sexual experience among racial/ethnic groups of teenaged women was used for numerical projections. These projections were used in a systems dynamics model which posits teen pregnancy risk as a stochastic process of contraceptive failure and sexual activity.

Prior contraceptive use among women who gave birth in the US-Mexico border region, 2005: the Brownsville-Matamoros Sister City Project for Women's Health.

Introduction: Dramatic population growth in the US-Mexico border region suggests more effective family planning services are needed, yet binational data are scarce. The Brownsville-Matamoros Sister City Project for Women's Health collected binational, standardized data from 947 postpartum women in Cameron County (Texas) and Matamoros (Tamaulipas, Mexico) hospitals from August through November 2005.

Methods: We analyzed these data to estimate the proportion of women with unintended pregnancy and the proportion of these women who reported contraceptive use, and to identify associated factors.

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.

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.

Attempted breastfeeding before hospital discharge on both sides of the US-Mexico border, 2005: the Brownsville-Matamoros Sister City Project for Women's Health.

Introduction: The US-Mexico border region has a growing population and limited health care infrastructure. Preventive health behaviors such as breastfeeding ease the burden on this region's health care system by reducing morbidity and health care costs. We examined correlates of attempted breastfeeding before hospital discharge on each side of the US-Mexico border and within the border region.

Cervical cancer screening among women who gave birth in the US-Mexico border region, 2005: the Brownsville-Matamoros Sister City Project for Women's Health.

Introduction: The objective of this study was to examine correlates of ever having had a Papanicolaou (Pap) test among women who recently delivered a live infant and who resided near the US-Mexico border.

Methods: This cross-sectional study included women who delivered a live infant in Matamoros, Mexico (n = 488) and Cameron County, Texas (n = 453). Women were interviewed in the hospital before discharge between August 21 and November 9, 2005.

BART to HIVEd: adapting an HIV education prevention program.

One of the fastest growing segments of the population infected with HIV is the nation's youths. Thus, prevention in this high-risk population is vital. The authors detail the process of adapting an evidence-based HIV/AIDS educational program (HIVEd) to the unique needs of high-risk youths in adjudicated and detained facilities and alternative high schools.

Adult age differences in multiple cognitive functions: differentiation, dedifferentiation, or process-specific change?

Adult age differences in covariance structures of latent variables of vocabulary, list recall, speed, working memory, and text recall, were analyzed to test hypotheses of structural changes with age. There were baseline data from 613 men and women aged 30-97, data from a second wave of testing from 322 people, and complete longitudinal data from 289 people. There were age differences in the size but not configuration of factor loadings cross-sectionally but not longitudinally.
