The Child Care Facility Schedule (CCFS) represents an effort to develop a measure to assess quality child care. Initially 80 criteria, covering 8 areas considered important for attaining quality, were defined. These were subsequently tested in three different cultural contexts: Athens (Greece), Manila (Philippines), and Ibadan (Nigeria). Reliability studies were conducted in Athens and Ibadan, and a validity study was carried out in Athens. Concurrent validity was established by comparing the CCFS scores with those obtained from an unstructured observation by an observer unfamiliar with the content of the Schedule. Criterion validity was examined by comparing the CCFS scores with those derived from another well-established measure. Factor and cluster analyses were used as a means for establishing construct validity. A general quality factor that tapped the contribution of the caretakers to quality was revealed, and a shorter 43-item version was recommended. The CCFS appears to identify differences among the various types of day care centres, and can be used for self-evaluation by the personnel of day care centres.

The objective of this study was to evaluate the determinants of weight gain during pregnancy. The study adopted a prospective cohort design with four follow-up waves and included a sample of 255 pregnant women that received prenatal care at a public health care facility in Rio de Janeiro, Brazil. A mixed-effects linear longitudinal regression model was used, having as the dependent variable the weight assessed in four follow-up waves, and as independent variables: demographic, socioeconomic, reproductive, behavioral, and nutritional data. Mean weight gain was 0.413kg per gestational week, consistent with recommendations by the Institute of Medicine. Per capita family income and smoking were associated with total weight gain during gestation. According to the longitudinal multiple linear regression model, age (² = 0.6315), menarche (² = -2.3861), triglycerides (² = 0.0437), blood glucose (² = 0.1544), and adequacy of energy consumption (² = -0.0642) were associated with gestational weight gain. Special attention should be given to these sub-groups, due to increased risk of excessive weight gain.

The relative importance of the aerosol transmission route for influenza remains contentious. To determine the potential for influenza to spread via the aerosol route, we measured the size distribution of airborne influenza A viruses. We collected size-segregated aerosol samples during the 2009–2010 flu season in a health centre, a day-care facility and onboard aeroplanes. Filter extracts were analysed using quantitative reverse transcriptase polymerase chain reaction. Half of the 16 samples were positive, and their total virus concentrations ranged from 5800 to 37 000 genome copies m −3 . On average, 64 per cent of the viral genome copies were associated with fine particles smaller than 2.5 µm, which can remain suspended for hours. Modelling of virus concentrations indoors suggested a source strength of 1.6 ± 1.2 × 10 5 genome copies m −3 air h −1 and a deposition flux onto surfaces of 13 ± 7 genome copies m −2 h −1 by Brownian motion. Over 1 hour, the inhalation dose was estimated to be 30 ± 18 median tissue culture infectious dose (TCID 50 ), adequate to induce infection. These results provide quantitative support for the idea that the aerosol route could be an important mode of influenza transmission.
