Randomized Controlled Trial Multicenter Study
Public parks and physical activity among adolescent girls.
Physical activity may be constrained or facilitated by local environments. The availability of neighborhood facilities for physical activity may be particularly relevant for youth, who are unable to drive and whose activity is often limited to the immediate distance they are able to walk or bicycle. Several studies have shown that proximity to recreational facilities and parks is one of the most important predictors of physical activity. Because the United States already has an extensive infrastructure of parks, with 70% of adults indicating that they live within walking distance of a park or playground, parks may be a potential venue for increasing physical activity. This might be particularly important for adolescent girls, whose physical activity levels decline substantially as they go through puberty. The goal of this study was to examine the association between park proximity, park type, and park features and physical activity in adolescent girls. ⋯ Adolescent girls who live near more parks, particularly near those with amenities that are conducive to walking and with active features, engage in more nonschool metabolic equivalent-weighted moderate/vigorous physical activity than those with fewer parks. Whether this is because of actual use of the parks or neighborhood choice could not be determined. Although the magnitude of the association between parks and additional minutes of metabolic equivalent-weighted moderate/vigorous physical activity was small for an individual, amounting to an average of 4%-6% of a girl's total nonschool metabolic equivalent-weighted moderate/vigorous physical activity, it is likely to have a large population-level association. Because of the potential population level impact, the use of parks to promote physical activity should be further studied.

Randomized Controlled Trial Multicenter Study
Reducing premature infants' length of stay and improving parents' mental health outcomes with the Creating Opportunities for Parent Empowerment (COPE) neonatal intensive care unit program: a randomized, controlled trial.
Although low birth weight premature infants and parents are at high risk for adverse health outcomes, there is a paucity of studies that test early NICU interventions with parents to prevent the development of negative parent-infant interaction trajectories and to reduce hospital length of stay. Our objective was to evaluate the efficacy of an educational-behavioral intervention program (ie, Creating Opportunities for Parent Empowerment) that was designed to enhance parent-infant interactions and parent mental health outcomes for the ultimate purpose of improving child developmental and behavior outcomes. ⋯ A reproducible educational-behavioral intervention program for parents that commences early in the NICU can improve parent mental health outcomes, enhance parent-infant interaction, and reduce hospital length of stay.

Tuberculosis control programs place an almost exclusive emphasis on adults with sputum smear-positive tuberculosis, because they are most infectious. However, children contribute a significant proportion of the global tuberculosis caseload and experience considerable tuberculosis-related morbidity and mortality, but few children in endemic areas have access to antituberculosis treatment. The diagnostic difficulty experienced in endemic areas with limited resources has been identified as a major factor contributing to poor treatment access. In general, there is a sense of scepticism regarding the potential value of symptom-based diagnostic approaches, because current clinical diagnostic approaches are often poorly validated. The natural history of childhood tuberculosis demonstrates that symptoms may offer good diagnostic value if they are well defined and if appropriate risk stratification is applied. This study aimed to determine the value of well-defined symptoms to diagnose childhood pulmonary tuberculosis in a tuberculosis-endemic area. ⋯ Pulmonary tuberculosis can be diagnosed with a reasonable degree of accuracy in HIV-uninfected children using a simple symptom-based approach. This offers the exciting prospect of improving treatment access for children, particularly in resource-limited settings where current access to antituberculosis treatment is poor.

Comparative Study
Variations in low birth weight and preterm delivery among blacks in relation to ancestry and nativity: New York City, 1998-2002.
Black women in the United States are more likely to give birth to preterm and low birth-weight infants than their white counterparts, but little is known about variation in birth outcomes within the black population. This study aimed to test the hypothesis that the risk of low birth weight and preterm birth within the black population varies by maternal ancestry and nativity. ⋯ Important health differences may be masked in studies that treat black women in America as a homogeneous group and do not take ethnic variation and nativity into account.

Practice Guideline Multicenter Study
Evaluation and development of potentially better practices to improve pain management of neonates.
Despite increased knowledge, improved options, and regulatory mandates, pain management of neonates remains inadequate, promoted by the ineffective translation of research data into clinical practice. The Neonatal Intensive Care Quality Improvement Collaborative 2002 was created to provide participating NICUs the tools necessary to translate research, related to prevention and treatment of neonatal pain, into practice. The objective for this study was to use proven quality improvement methods to develop a process to improve neonatal pain management collaboratively. ⋯ Collaborative use of quality improvement methods resulted in the creation of self-directed, efficient, and effective processes to improve neonatal pain management. Group establishment of potentially better practices, collective and site-specific goals, and extensive baseline data resulted in accelerated implementation of clinical practices that would not likely occur outside a collaborative setting.
