Abstract

Objective

Preterm delivery, which is the most common cause of neonatal deaths and the second most 

common cause of death in children aged <5 years, is defined as birth before 37 weeks of 

pregnancy. The rate of preterm delivery worldwide ranges  from 5% to 18%, and this rate has 

gradually increased in recent years.

In this study, we evaluated the relationship between preterm delivery and the average Hb levels 

of pregnant women who attended at least four pregnancy follow-up visits at family health centres 

and in whom Hb levels were measured in the first and second trimesters of pregnancy. Our 

objective in this study, which is the first study to evaluate the relationship between Hb levels and 

preterm delivery in Turkey, was to examine the relationship between preterm delivery and 

maternal anaemia.

Material and Methods

This retrospective cohort study was conducted in eight different family health centres located in 

the provinces of Rize and Istanbul between 1 December 2017 and 1 March 2017. The study 

included a total of 483 women; 294 of them had normal delivery and 189 had preterm delivery. 

All mothers participating in the study had attended at least three pregnancy follow-up visits with 

their family physician (at least one visit in each trimester) as  per the pregnancy follow-up protocol set out by the Ministry of Health. Hb values of all the women participating in the study 

were measured in the first and second trimesters, and the average Hb values were calculated.

Results

The mean Hb level during pregnancy was 10.89  ± 0.85 mg/dl  in women who delivered preterm 

babies; 68.8% (n = 130) of these women had anaemia. The mean Hb level during pregnancy was 

11.66 ± 0.85 mg/dl in control women who delivered full-term babies; 76.19% (n = 224) of these 

women were non-anaemic. There was a significant difference between both groups (p < 0.001). 

The mean age of the mothers delivering preterm babies was  30.56  ± 5.84 years, and this was 

lower than that in the control group (32,23± 5,89) (p < 0.05)

Conclusions

Anaemia during pregnancy might be related with preterm delivery and this must be corrected.

Pregnant women should undergo more stringent follow-up programmes.
