An integrated postpartum health-care program was established by the Consultorio San Luis de Huechuraba (CSLH), a nongovernmental organization in a neighborhood of extreme poverty in Santiago, Chile. The main components were education, maternal and infant health care, support for the mothers, and active participation of women from the community served. The program was evaluated through indicators of contraceptive use, breastfeeding performance, infant growth and health, and a qualitative assessment of women's satisfaction. Controls were women of similar characteristics attending the nearby public clinic. Acceptability of contraceptive methods was similar but contraceptive options differed between clinics. The total number of pregnancies and of respondents lost to follow-up was significantly higher for the public clinic than for the CSLH. Breastfeeding duration was significantly longer and infant growth and health were found to be significantly better at the CSLH than at the public clinic. Women valued being treated with respect, receiving education and support, and being offered timesaving services and wider contraceptive choices at the CSLH. This study demonstrates that such interventions are possible for poor communities, providing significant advantages for women and children.

Family factors, such as poor family functioning and trauma, have been associated with negative outcomes for homeless adolescents. Further study is needed to better understand how family factors and trauma jointly relate to mental health problems and externalizing behaviors among homeless adolescents. Structural equation modeling was used to examine the influence of trauma (encompassing traumatic events experienced prior to, and after, becoming homeless) and family factors (poor family functioning and family conflict) on mental health problems and externalizing behaviors (substance use, delinquent behaviors, and sexual risk) among 201 homeless adolescents, ages 12 to 17 years. Trauma, poor family functioning, and family conflict significantly predicted greater mental health problems, delinquent behaviors, high-risk sexual behaviors and substance use. Overall, the findings suggest that family factors appear to be key to understanding mental health problems and externalizing behaviors among homeless adolescents. Implications, limitations and future directions are addressed.

The level of physical activity in this population is acceptable, although there are sex differences and there is a declining trend through the adolescence.

Health inequities and disparities among various racial/ethnic minority, sexual minority, and rural populations are the focus of increasing national efforts. Three health problems disproportionately affecting these populations—HIV/AIDS, substance abuse, and trauma—deserve particular attention because of their harmful effects on health across the life span. To address these problems, our training program, the UCLA HIV/AIDS, Substance Abuse, and Trauma Training Program (HA-STTP), mentors and trains early career behavioral health scientists to conduct research using scientifically sound, culturally collaborative, and population-centered approaches. HA-STTP has been highly successful in training a diverse, productive, nationwide group of scholars. The program provides 2 years of training and mentorship to 20 (5 per year over 4 years) scholars. It is unique in its attention to traumatic stress as a form of dysregulation, particularly as experienced by underserved populations. Furthermore, our training program embraces a uniquely comprehensive, culturally grounded understanding of traumatic stress and its implications for substance abuse and HIV. HA-STTP advances scholars’ knowledge of the interconnections among substance abuse, HIV/AIDS, traumatic stress, and health disparities, particularly in underrepresented populations; provides intensive mentorship to support scholars’ research interests and career trajectories; capitalizes on a multidisciplinary, multiracial/ethnic network of expert faculty; and evaluates the program’s impact on scholars’ knowledge and productivity. By fostering the growth of scholars committed to conducting research with underrepresented populations that are disproportionately affected by HIV/AIDS, substance abuse, and traumatic stress, this program enhances nationwide efforts to diminish the prevalence of these problems and improve health and quality of life.
