OBJECTIVES We examined racial and ethnic disparities in the total potential burden of asthma in low-income, racially/ethnically heterogeneous Chicago schools. METHODS We used the Brief Pediatric Asthma Screen Plus (BPAS+) and the Spanish BPAS+, validated, caregiver-completed respiratory questionnaires, to identify asthma and possible asthma among students in 14 racially/ethnically diverse pub...

Breastfeeding practices in Italy need to be promoted and monitored with updated and standard data The objective of this study is to provide estimates of the prevalence of breastfeeding and exclusively breastfeeding and to identify factors that may be modifie...

In this paper, aimed at suitable planning, analysis, and follow-up of treatment, control, and eradication in a human onchocerciasis program, were studied 27 geographic areas and examined 3,974 inhabitants. Four epidemiological areas with different prevalences were identified and stratified.

BACKGROUND Low haemoglobin concentrations and anaemia are important risk factors for the health and development of women and children. We estimated trends in the distributions of haemoglobin concentration and in the prevalence of anaemia and severe anaemia in young children and pregnant and non-pregnant women between 1995 and 2011. METHODS We obtained data about haemoglobin and anaemia for ch...

In visual search tasks, the ratio of target-present to target-absent trials has an important effect on miss rates. The low prevalence effect indicates that we are more likely to miss a target when it occurs rarely rather than frequently. In this study, we examined whether probability cueing modulates the miss rate and the observer's criterion. The results indicated that probability cueing affec...

BACKGROUND Communities and nations seeking to foster social responsibility in their youth are interested in understanding factors that predict and promote youth involvement in public activities. Orphans and separated children (OSC) are a vulnerable population whose numbers are increasing, particularly in resource-poor settings. Understanding whether and how OSC are engaged in civic activities i...

It is imperative to identify disparities in physical activity in the country, to guide the design of public policies aimed at...

OBJECTIVE To describe prevalences and trends of overweight and obesity/OW&OB in Mexican children from 1988 to 2006 at the national level and by relevant subpopulations. MATERIAL AND METHODS Prevalences of OW&OB in children aged 2-18 years were estimated using body mass index data from three national surveys conducted in 1988, 1999 and 2006. RESULTS Prevalences of OW&OB are high in children ...

The objective of the study was to estimate the prevalence of extreme anthropometric measurements in children indicative of their nutritional status. A cross-sectional study was conducted in a random sample of 1,386 children under five in the state of Alagoas, northeastern Brazil. The prevalence of deficits (z <-2; WHO-2006 standard) for weight-for-age (underweight), weight-for-height (wasting) ...

To determine breast-feeding trends in the Region of the Americas and compare them with those observed in Cuba in the last decade, information was complied from a select group of national surveys conducted in the 1970s on the prevalence and duration of breast-feeding and then compared with information from a survey carried out in Cuba in 1973. In addition, data were taken from document HPN/92.7 ...
