Abstract

Racial/ethnic disparities in rates of low birthweight (LBW) are well established, as are racial/ethnic differences in health outcomes over the life course. Yet, there is little empirical work examining whether the consequences of LBW for subsequent child health vary by race, ethnicity, and national origin. Using data from the 1998-2016 National Health Interview Survey, we examined whether racial, ethnic, and national differences existed in the association between LBW and subsequent health outcomes, namely being diagnosed with a developmental disability, asthma diagnosis, and poorer general health. Children born with LBW consistently had poorer health relative to children born with normal birthweight. There was no systematic evidence that the linkages between LBW and subsequent health were weaker for one racial/ethnic/national origin group relative to others. LBW was associated with subsequent poorer health. There was no systematic evidence that the link between LBW and subsequent child health were weaker for one racial/ethnic/national origin group relative to others. Together, these findings highlight the importance of reducing race/ethnic disparities in rates of LBW as a way of eradicating inequalities in childhood health.

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
