Pediatric allergy and immunology in Spain

The data of the ISAAC project in Spain show a prevalence of childhood asthma ranging from 7.1% to 15.3%, with regional differences; a higher prevalence, 22.6% to 35.8%, is described for rhinitis, and atopic dermatitis is found in 4.1% to 7.6% of children. The prevalence of food allergy is 3%. All children in Spain have the right to be visited in the National Health System. The medical care at the primary level is provided by pediatricians, who have obtained their titles through a 4-yr medical residency training program. The education on pediatric allergy during that period is not compulsory and thus very variable. There are currently 112 certified European pediatric allergists in Spain, who have obtained the accreditation of the European Union of Medical Specialist for proven skills and experience in pediatric allergy. Future specialists in pediatric allergy should obtain their titles through a specific education program to be developed in one of the four accredited training units on pediatric allergy, after obtaining the title on pediatrics. The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) gathers over 350 pediatric allergists and pediatricians working in this field. SEICAP has a growing activity including yearly congresses, continued education courses, elaboration of technical clinical documents and protocols, education of patients, and collaboration with other scientific societies and associations of patients. The official journal of SEICAP is Allergologia et Immunophatologia, published every 2 months since 1972. The web site of SEICAP, http://www.seicap.es, open since 2004, offers information for professionals and extensive information on pediatric allergic and immunologic disorders for the lay public; the web site is receiving 750 daily visits during 2011. The pediatric allergy units are very active in clinical work, procedures as immunotherapy or induction of oral tolerance in food allergy, contribution to scientific literature, and collaboration in international projects.     

Early life predictors of body composition trajectories from adolescence to mid-adulthood

Objectives

Guatemala has experienced rapid increases in adult obesity. We characterized body composition trajectories from adolescence to mid-adulthood and determined the predictive role of parental characteristics, early life factors, and a nutrition intervention.

Methods

One thousand three hundred and sixty-four individuals who participated as children in a nutrition trial (1969–1977) were followed prospectively. Body composition characterized as body mass index (BMI), fat mass index (FMI), and fat-free mass indices (FFMI), was available at four ages between 10 and 55 years. We applied latent class growth analysis to derive sex-specific body composition trajectories. We estimated associations between parental (age, height, schooling) and self-characteristics (birth order, socioeconomic status, schooling, and exposure to a nutrition supplement) with body composition trajectories.

Results

In women, we identified two latent classes of FMI (low: 79.6%; high: 20.4%) and BMI (low: 73.0%; high: 27.0%), and three of FFMI (low: 20.2%; middle: 55.9%; high: 23.9%). In men, we identified two latent classes of FMI (low: 79.6%; high: 20.4%) and FFMI (low: 62.4%; high: 37.6%), and three of BMI (low: 43.1%; middle: 46.9%; high: 10.0%). Among women, self's schooling attainment inversely predicted FMI (OR [being in a high latent class]: 0.91, 95% CI: 0.85, 0.97), and maternal schooling positively predicted FFMI (OR: 1.16, 95% CI: 0.97, 1.39). Among men, maternal schooling, paternal age, and self's schooling attainment positively predicted FMI. Maternal schooling positively predicted FFMI, whereas maternal age and paternal schooling were inverse predictors. The nutrition intervention did not predict body composition class membership.

Conclusions

Parents' age and schooling, and self's schooling attainment are small but significant predictors of adult body composition trajectories.
