Introduction:

The association of asthma and obesity has increased its prevalence in recent years.

Objectives:

Characterize asthmatic children and adolescents with associated obesity.

Methods:

Descriptive, cross-sectional and prospective research, 2017 - 2018, Pneumology Service, Centro Habana University Pediatric Hospital. 43 asthmatic patients from 5 to 18 years old with associated exogenous obesity were assessed. Age, sex, family history of asthma and obesity, severity and degree of asthma control were studied. Studies were conducted to evaluate lipid and carbohydrate metabolism.

Results:

Age distribution was similar (schoolers, early and late adolescence), predominated male sex in schoolchildren (11 of 16 - 68.7 %) and the female in late adolescence (12 of 15 -80 %). Family history of obesity was reported in 5 patients (11.6 %) and obesity-associated asthma in 26 (60.5%); most had mild persistent asthma (38 -88.4 %) poorly controlled: 28 uncontrolled (65.1 %) and 10 partially controlled (23.3 %). Two patients had carbohydrate intolerance (4.7 %), one of them with insulin resistance. Dyslipidemia was the most common metabolic disorder: serum cholesterol increased in 23 - 53.5 %, high LDLc in 13 - 30.2 %, and low HDLc in 10 - 23.3 %.

Conclusions:

Asthmatic children with a family history of obesity are also at high risk of being obese, which can make difficult to control asthma; metabolic alterations are common in them.
