[The influence of Sudden Infant Death Syndrome (SIDS) risk factors on health, growth and development in the first year of life. A preliminary report].
OBJECTIVE
To establish the occurrence of SIDS risk factors (including 'removable' ones) and the incidence of the ecg long QT interval (accepted as a risk factor) and their influence upon infants development and morbidity.


METHODS
A group of 98 infants from normal birth at term to the end of first year of life was observed. The data sources were as follows: 1) a questionnaire filled by mothers before discharge front maternity ward, 2) records of four consecutive medical examinations (including ecg records) performed on 3rd day and 3rd, 6th and 12th month of life. Chi-Square test and Fisher test were used.


RESULTS
The most often identified risk factors were: prone sleeping position of infant (60.2%), environmental and maternal tobacco smoking (40.8%) and bed sharing practices (32.6%). A significant but transient signs of delay in psychomotor development (in motor zone) as well as more frequent respiratory tract infections in infants sleeping prone were noted. There were no deaths in the observed group neither cases of long QT interval.


CONCLUSIONS
1) the most frequently occurring SIDS risk factors are: environmental tobacco smoking, infant prone sleeping and bed sharing, 2) these inappropriate nursing practices and improper habits of adult family members known as a 'removable' SIDS risk factors have a bad effect on infant health and development, 3) identification of SIDS risk factors in an infant does not predict crib death.
