Abstract

Introduction: The high incidence of low birth weight in relation to the presence of prematurity, smoking, infection and hemorrhage is a problem that may have significant implications for maternal and child health.

Objective: The aim of the study was to associate prematurity, smoking, infection and hemorrhage with low birth weight.

Methods: The study adopted a relational and observational approach, being retrospective and cross-sectional in its design, as well as being analytical in the statistical analysis used to examine the relationships between variables. The study population comprised 377 pregnant patients who received medical care at the Hospital General Docente Ambato, Ecuador. The Chi-square test of independence was developed with the support of SPSS Statistics software. It was assumed that if the calculated value of the test was greater than the critical value, it would be concluded that the association between the variables was significant and, therefore, the null hypothesis would be rejected.

Results: It was evidenced that prematurity is indeed associated with low birth weight (X2 = 14.291 and p-value = <0.01), as is smoking (X2 = 19.242 and p-value = <0.01), hemorrhage (X2 = 25.626 and p-value =<0.01) and infection (X2 = 16.333 and p-value = <0.01).

Conclusions: The results evidenced that prematurity, smoking, infection and hemorrhage are significantly associated with low birth weight.
