OBJECTIVE: To study the morbidity rate of children's cerebral palsy (CP) in Baku in children born in 2006-2016.
MATERIAL AND METHODS: During 2006-2016, 35 891, 37 130, 37 459, 40 050, 34 726, 34 192, 33 258, 30 373, 29 722, 29 654 and 29 564 children were born in Baku. CP was diagnosed in 1162 of these children. Newborns and children with CP were divided into 3 groups by body mass (<1500; 1500- 2500; 2500 and more) and into 4 groups by the gestational age (<28, 28-32; 32-36, 36 and more weeks). The morbidity rates were detected in these groups. The statistical significance of morbidity rates was assessed by χ criteria.
RESULTS: The morbidity rate of CP changed within the interval 0.27% (95% CI 0.22-0.33%) in 2006 to 0.37% (95% CI 0.30-0.44%) in 2016. The difference between the minimum and maximum morbidity rates was not statistically significant (>0.05). The morbidity rate of CP in newborns with body mass <1500 grams was 10.35% (95% CI 0-21.65%) and was 6.1 times higher than in the group of newborns weighing 1500-2500 grams at birth (1.72%; 95% CI 0.20-3.25%) and 30.4 times higher than in the group of newborns with body mass ≥2500 grams (0.34%; 95% CI 0.27-0.41%). The difference between morbidity rates of CP in groups depending on birth body mass was significant (<0.0001).
CONCLUSION: The incidence rate of CP in a cohort of newborns during the first 60 months after birth in 2006-2016 fluctuated in the range of 0.27-0.37% and had a weak growth trend. The morbidity rate of children's CP is significantly higher in children with body mass at birth <1500 (10.34%) and 1500-2500 grams (1.72%) than in children with body mass at birth 2500 and more grams (0.34%). The gestational age of newborns affects the morbidity rate of CP, which is 5.48; 1.78 and 0.34% at gestational age <32, 32-36 and ≥36 weeks. The structure of subtypes of this pathology is close to that in other populations against the background of the comparative morbidity rate of CP in Baku, the proportion of spastic unilateral, spastic bilateral, dyskinetic and atonic CP is 35.2; 58.0; 3.9 and 1.4%, respectively.
