00:00.280 --> 00:02.860
This graph shows the results of

00:02.860 --> 00:05.060
a study carried out
in the Netherlands.

00:05.060 --> 00:06.820
The study explored the rates of

00:06.820 --> 00:09.460
developmental delay in
preschool children,

00:09.460 --> 00:12.420
measured using the ages
and stages questionnaire

00:12.420 --> 00:16.320
completed by parents when the
children were four years of age.

00:16.320 --> 00:19.320
The x axis along the
bottom of the graph

00:19.320 --> 00:22.680
shows the five areas of
development that were assessed.

00:22.680 --> 00:24.800
For each area of development,

00:24.800 --> 00:26.440
the graph shows the results for

00:26.440 --> 00:28.340
children who were
born at full term,

00:28.340 --> 00:30.600
shown in the dark grey bars,

00:30.600 --> 00:32.660
moderately or late pre term,

00:32.660 --> 00:34.580
shown in the light grey bars,

00:34.580 --> 00:36.100
and very pre term,

00:36.100 --> 00:37.855
shown in the blue bars.

00:37.855 --> 00:41.370
Y axis on the left hand
side of the graph shows

00:41.370 --> 00:42.770
the percentage of children in

00:42.770 --> 00:45.370
each group that had
developmental delay.

00:45.370 --> 00:47.410
The higher the bars on the graph,

00:47.410 --> 00:50.970
the higher the proportion of
children with developmental delay.

00:50.970 --> 00:53.330
Looking across the
graph as a whole,

00:53.330 --> 00:55.270
you can see that the proportion of

00:55.270 --> 00:57.410
children with
developmental delay was

00:57.410 --> 01:00.090
highest amongst those
born very pre term

01:00.090 --> 01:02.550
before 32 weeks of gestation.

01:02.550 --> 01:04.930
This was the same for every area

01:04.930 --> 01:06.925
of development that was assessed.

01:06.925 --> 01:09.500
Moderately and late
pre term children born

01:09.500 --> 01:12.360
at 32 to 36 weeks of gestation,

01:12.360 --> 01:15.300
had higher rates of developmental
delay than children

01:15.300 --> 01:18.760
born at full term in every
area of development.

01:18.760 --> 01:22.760
But this was not as high as for
children born very pre term.

01:22.760 --> 01:26.080
For example, looking at
the bars on the left,

01:26.080 --> 01:28.900
you can see that 3.5% of

01:28.900 --> 01:32.460
full term children had delayed
fine motor development,

01:32.460 --> 01:36.600
compared with 8% of children born
late and moderately pre term,

01:36.600 --> 01:39.680
and 12% of children
born very pre term.

01:39.680 --> 01:42.200
The same pattern of
results was found across

01:42.200 --> 01:45.565
all five areas of development
that were assessed.

01:45.565 --> 01:49.310
In summary, this graph
shows that on average,

01:49.310 --> 01:51.070
the earlier a baby is born,

01:51.070 --> 01:53.390
the greater the risk she or he will

01:53.390 --> 01:56.170
have developmental delay
in the preschool years,

01:56.170 --> 02:00.590
and this is evident in
all areas of development.
