In Chile the National Institute of Statistics established that this age has remained around 23 years for more than two decades. Motherhood postponement may be modulated by socioeconomic status. To determine whether the age at first delivery is higher in a private clinic compared to a public hospital. Two cohorts of primiparous women delivering in 1998 and 2008 in the public hospital San Borja Arriarán (HSBA) and a private setting Clínica Las Condes (CLC), were analyzed. The age of all delivering women was significantly lower in HSBA than in CLC in both study periods (26.3 ± 0.8 and 25.7 ± 0.9 compared to 31.6 ± 0.1 and 32.7 ± 0.1 years, respectively). Likewise, the frequency of adolescent pregnancy was significantly higher in HSBA than CLC in both study periods (38.8 and 42.2% compared to 1.7 and 1.6% respectively). The age at first delivery was significantly lower i...

The city of Atlanta hosted its first Open Streets event, Atlanta Streets Alive (ASA), in May 2010. An evaluation of the first 5 ASA events from May 2010 to May 2012 was conducted. The purpose was to learn about the characteristics of ASA participants, the influence of the event on their PA, and perceptions of safety and neighborhood social capital.Methods:ASA’s evaluation had 2 components: participant counts and a participant survey. Characteristics of participation were compared among the 3 different events in which surveys were conducted using the Pearson χ2 test and F test as appropriate.Results:The estimated participation at ASA increased from nearly 3,500 (ASA 1 to 4) to 12,520 (ASA 5). The number of events increased to 3 per year for a total of 10 ...

We assessed existing information about the Ciclovía as a public health strategy and proposed next steps for research and public health practice. We conducted a systematic search of peer-reviewed and other literature, which was complemented by expert interviews and consultation. We reviewed 38 Ciclovías from 11 countries. Most programs (84.2%) take place in urban settings. The programs range from 18-64 events per year (54 + or - 24.6; 52 [mean + or - standard deviation; median]) with events lasting from 2-12 hours (6 + or - 2.4; 6). The length of the streets ranges from 1-121 km (14.6 + or - 22.1; 7), and the estimated number of participants per event ranges from 60-1,000,000 persons (61,203 + or - 186,668; 3810). Seventy-one percent of the programs include physical activity classes and in 89%...

We describe the process of developing logic models (LM) of PA community interventions from Curitiba, Brazil, and discuss influential factors. The year-long process included engaging stakeholders involved in the promotion of PA in Curitiba, working with stakeholders to describe the programs and their goals, and developing LMs for the 2 main secretaries promoting PA in the city. As a result of stakeholder interviews and discussion and the development of the LMs, local officials are coordinating programming efforts and considering ways the programs can be more complementary. The process has prompted program managers to identify overlapping programs, refine program goals, and identify gaps in programming. It also helped to frame evalua...

Feline leukemia virus (FeLV) infection is unique as a naturally occurring, diametric example of effective vs. ineffective retroviral containment by the host. We developed a sensitive quantitative real-time DNA PCR assay specific for exogenous FeLV to further explore the FeLV-host relationship. By assaying p27 capsid antigen in blood and FeLV DNA in blood and tissues of successfully vaccinated, unsuccessfully vaccinated, and unvaccinated pathogen-free cats, we defined four statistically separable classes of FeLV infection, provisionally designated as abortive, regressive, latent, and progressive. These host-virus relationships were established by 8 weeks post-challenge and could be maintained for years. Real-time PCR methods offer promise in gaining deeper insight into the mechanisms of FeLV infection and immunity.
