Dataset Information

Prevalence and risk factors for wheeze, decreased forced expiratory volume in 1 s and bronchoconstriction in young children living in Havana, Cuba: a population-based cohort study.

ABSTRACT:

Objectives

Asthma has not been extensively studied in low-income and middle-income countries, where risk factors and access to treatment may differ from more affluent countries. We aimed to identify the prevalence of asthma and local risk factors in Havana, Cuba.

Setting

Four municipalities in Havana, Cuba.

Participants

A population-based cohort study design of young children living in Havana, Cuba. Children were recruited from primary care centres at age 12-15 months.

Primary and secondary outcome measures

Data on wheeze in the past 12 months, asthma treatment and environmental exposures collected regularly until the age of 6 years, when forced expiratory volume in 1 s (FEV₁) and reversibility to aerosolised salbutamol were also measured.
