Gender differences in the perception of asthma respiratory symptoms in five Latin American countries.

OBJECTIVES

To determine the differences between sexes in perceptions of asthma symptoms, asthma control, daily activities, and symptom exacerbation in Latin American countries.

METHODS

This cross-sectional study was performed using data from the Latin America Asthma Insight and Management (LA-AIM) study (n = 2167) carried out in Argentina, Brazil, Mexico, Venezuela, and Puerto Rico. Face-to-face interviews were conducted, and patients orally completed a 53-question survey assessing five main domains of asthma: symptoms, impact on daily activities, disease control, exacerbation, and treatment/medication.

RESULTS

Of the 2167 participants, 762 (35.2%) were males and 1405 (64.8%) were females. Male participants smoked more than females, but history of rhinitis and allergies was more common in females (p < 0.05). Women aged 18-40 years had a higher proportion of uncontrolled asthma compared to men of the same age (37.8% and 30.0%, respectively). A higher proportion of symptomatic females reported more frequent symptoms (daytime cough, shortness of breath, breathlessness/wheezing, sputum, tightness in the chest, etc.) than males (p < 0.05). Females also experienced more limitations in sports/recreational activities, normal physical exertion, social activities, sleep, and daily activities. Females consulted with health professionals more often than males (67.8% and 59.6%, respectively; p < 0.05). Asthma caused a feeling of lack of control over life in 42.6% of females and 31.4% of males.

CONCLUSION

In Latin America, females report more asthma symptoms, poorer asthma control, more impact on their daily activities, and more visits with health professionals than males.
