2. Key fi nd<strong>in</strong>gs of <strong>the</strong> CEMACH <strong>Diabetes</strong> Programme<br />

The three modules of <strong>the</strong> CEMACH <strong>Diabetes</strong> Programme (<strong>the</strong> CEMACH survey of diabetes maternity<br />

services, <strong>the</strong> descriptive study of 3808 pregnancies to women with type 1 and type 2 diabetes, and <strong>the</strong><br />

national enquiry <strong>in</strong>to 521 diabetic pregnancies), have identifi ed a number of key fi nd<strong>in</strong>gs. These fi nd<strong>in</strong>gs<br />

<strong>are</strong> summarised <strong>in</strong> this chapter. Additional details can be found <strong>in</strong> <strong>the</strong> two previous reports of <strong>the</strong> <strong>Diabetes</strong><br />

Programme and <strong>in</strong> <strong>the</strong> relevant chapters of this report.<br />

2.1 Social and demographic characteristics<br />

Women with type 1 diabetes accounted for 73% (2767/3808) of women <strong>in</strong> <strong>the</strong> descriptive study<br />

and women with type 2 diabetes accounted for 27% (1041/3808) of women <strong>in</strong> <strong>the</strong> descriptive study. 1<br />

Women with type 2 diabetes <strong>we</strong>re more likely to be older, multiparous, live <strong>in</strong> a deprived <strong>are</strong>a and<br />

come from a Black, Asian or O<strong>the</strong>r Ethnic m<strong>in</strong>ority group, than women with type 1 diabetes. 1<br />

In <strong>the</strong> enquiry, maternal social deprivation (based on postcode of residence) was associated with<br />

poor <strong>pregnancy</strong> outcome.<br />

Smok<strong>in</strong>g before <strong>pregnancy</strong> <strong>in</strong> women with diabetes was associated with an <strong>in</strong>creased risk of poor<br />

<strong>pregnancy</strong> outcome. Fur<strong>the</strong>r work is required to elucidate <strong>the</strong> <strong>in</strong>terrelationship and relative contribution<br />

of factors such as smok<strong>in</strong>g, deprivation and ethnicity to <strong>pregnancy</strong> outcome <strong>in</strong> women with diabetes.<br />

2.2 Cl<strong>in</strong>ical characteristics<br />

In <strong>the</strong> descriptive study, <strong>the</strong>re was a 36% preterm delivery rate and a 67% caes<strong>are</strong>an section rate for<br />

women with diabetes. 1 This comp<strong>are</strong>s to a 7% preterm delivery rate and a 22% caes<strong>are</strong>an section rate<br />

<strong>in</strong> <strong>the</strong> general maternity population. 2<br />

In <strong>the</strong> descriptive study, 21% of s<strong>in</strong>gleton babies of women with diabetes had a birth <strong>we</strong>ight of 4000g or more<br />

comp<strong>are</strong>d to 11% of s<strong>in</strong>gleton babies <strong>in</strong> <strong>the</strong> general maternity population <strong>in</strong> England, 2002-03. 1 8% of babies<br />

<strong>in</strong> <strong>the</strong> descriptive study had shoulder dystocia, comp<strong>are</strong>d with 3% <strong>in</strong> a regional general maternity population. 3<br />

There was a ten-fold <strong>in</strong>creased <strong>in</strong>cidence of Erb’s palsy <strong>in</strong> babies of women with diabetes comp<strong>are</strong>d<br />

to babies <strong>in</strong> <strong>the</strong> general maternity population <strong>in</strong> <strong>the</strong> UK. 1, 4<br />

Nearly half of women <strong>in</strong> <strong>the</strong> enquiry had recurrent hypoglycaemia dur<strong>in</strong>g <strong>pregnancy</strong> and more than a tenth<br />

had at least one severe hypoglycaemic episode requir<strong>in</strong>g external help. There was no evidence from casecontrol<br />

analysis that hypoglycaemia was associated with a poor <strong>pregnancy</strong> outcome for <strong>the</strong> baby.<br />

2.3 Pregnancy outcomes<br />

In <strong>the</strong> descriptive study, women with diabetes had signifi cantly <strong>in</strong>creased risks of adverse <strong>pregnancy</strong><br />

outcome comp<strong>are</strong>d to <strong>the</strong> general maternity population: a fi vefold <strong>in</strong>creased risk of stillbirth, a threefold<br />

<strong>in</strong>creased risk of per<strong>in</strong>atal mortality and a twofold <strong>in</strong>creased risk of fetal congenital anomaly. 1<br />

A number of demographic and cl<strong>in</strong>ical characteristics, social and lifestyle factors, and cl<strong>in</strong>ical c<strong>are</strong> factors<br />

<strong>we</strong>re associated with poor <strong>pregnancy</strong> outcome, and <strong>are</strong> discussed <strong>in</strong> detail <strong>in</strong> o<strong>the</strong>r chapters of this report.<br />
