Background: The relationship between parent-reported and measured height and weight is not well established in schoolchildren. This relationship has never been studied in asthmatic children. The objective of this study is to test the validity of the parent-reported weight and height for defining obesity by BMI and to know whether the perception of this height and weight changes when the child suffers from asthma. Methods: All classes of children of the target ages of 6–8 years (n = 1,672, participation rate 70.2%) of all schools in four municipalities of Murcia (Spain) were included. Parents were asked about their children’s weight and height using a questionnaire which included the International Study of Asthma and Allergies in Childhood (ISAAC) core questions on asthma. Parents were not aware that their children were going to be weighed and measured within 1 week’s time. Measurements were performed using a rigid stadiometer to the nearest 0.1 cm and a scale to the nearest 0.1 kg. Results: The bias (reported minus real) was, respectively, for nonasthmatics and asthmatics: weight +0.42 kg (95% CI +0.24; +0.59 kg) versus +0.97 kg (+0.50; +1.44 kg), height +2.37 cm (+2.06; +2.68 cm) versus +2.87 cm (+1.87; +3.87 cm); BMI –0.39 kg/m² (–0.52; –0.23 kg/m²) versus –0.23 kg/m² (–0.58; +0.13 kg/m²). Diagnostic accuracy of obesity calculated from reported measurements was, respectively, for nonasthmatics and asthmatics: sensitivity 78.0 versus 77.8%, specificity 96.2 versus 94.5%, positive predictive value 77.2 versus 73.7% and negative predictive value 96.4 versus 91.7%. Conclusions: Reported weights and heights had large biases, comparable between parents of both asthmatic and those of nonasthmatic children. However, this information could be reasonably valid for classifying children as obese or nonobese in large epidemiological studies.

The aim of this study was to evaluate the data on the main imported infectious diseases and public health issues arising from the risk of transmission of tropical and common diseases in the immigrant population. During the period of study, 2,426 immigrants were attended in the Tropical Medicine Unit of the Hospital of Poniente. For each patient, a complete screening for common and tropical diseases was performed. The prevalence and main features of intestinal and urinary parasites, microfilarias, Chagas disease, malaria, hepatitis B (HBV) and C (HCV) viruses, extrapulmonary tuberculosis and syphilis was investigated taking into account the length of stay in Spain. Sub-Saharan Africa patients who had lived for <3 years in Spain had a high significantly number of infections produced by hookworms, Ascaris lumbricoides, Trichuris trichiura, Schistosoma mansoni, Giardia lamblia, Entamoeba histolytica/dispar and Plasmodium spp. In patients who had lived for more than 3 years, there were significantly high rates of HBV infections, although HBV rates in sub-Saharan African patients are high even if the patients have been in Spain for <3 years. However, patients with large stays in Spain had also an important number of parasitological diseases. The main objective of the diagnosis is to avoid important public health problems and further complications in patients. It is advisable to carry out a screening of the main transmissible infections in all immigrant population regardless of the time outside their country. This screening should be individualized according to the geographical area of origin.

The aim of this study is to describe the epidemiological profile, clinical characteristics, and microbiological findings in African immigrants newly arrived to Spain attended at a specialized reference unit from October 2004 to February 2017. A common protocol for the screening of imported and cosmopolitan diseases was designed to evaluate patients with ≤ 12 months of stay in Spain. A total of 523 patients were included in the study, 488 (93.3%) of sub-Saharan origin. A high number of helminthic infections were diagnosed in sub-Saharan patients, including geohelminthiasis (hookworms 14.3%; 4.1%; 3.1%), schistosomiasis (12.3%), strongyloidiasis (17.2%), and filariasis (8.4%). Thirty-five patients (7.2%) had malaria, most by Among communicable diseases, 33.6% of sub-Saharans presented HBsAg positivity compared with 5.7% of North African patients ( = 0.001). Thirteen patients were diagnosed with active tuberculosis. Seventy percent of the sub-Saharans and 40% of the North Africans who were tested had a latent tuberculosis infection (LTI). Treatment of LTI was administered in selected cases (14%), achieving end of treatment in 80% of them. In light of these results, effective screening strategies, particularly within the sub-Saharan immigrant population, including potentially communicable diseases and certain potentially serious parasitic diseases (, ), should be implemented. It is necessary to facilitate fully and free of charge access to the public health system to newly arrived immigrants, as well as to implement programs and actions aimed at favoring care and follow-up, especially for communicable diseases. Empirical treatment of some parasitic diseases could be a cost-effective action.
