“…Information on parity and age at first childbirth was retrieved from a questionnaire provided at baseline examinations where all women were 44 years or older, thus unlikely to have additional children following baseline. A previous study has confirmed selfreported parity to be highly accurate, 14 hence, we consider this information to be valid.…”

The aim of the present study was to examine parity and age at first childbirth, in relation to the risk of specific breast cancer subgroups. A prospective cohort, The Malmö Diet and Cancer Study, including 17,035 women were followed with linkage to Swedish Cancer Registry until December 31, 2004. A total of 622 incident breast cancers were diagnosed during follow‐up and were evaluated regarding invasiveness, tumour size, axillary lymph node status, Nottingham grade, tumour proliferation (Ki67), HER2, cyclin D1 and p27. The tumours were also examined for WHO type and hormone receptor status. Nulliparity was associated with an overall increased risk of breast cancer, although not statistically significant (the relative risk was 1.39 with a 95% confidence interval of 0.92–2.08). Nulliparity was also associated with large tumours (>20 mm) (1.89: 0.91–3.91), high Ki67 levels (1.95: 0.93–4.10), high cyclin D1 levels (2.15: 0.88–5.27), grade III (2.93: 1.29–6.64) and HER2 positive tumours (3.24: 1.02–10.25). High parity was not statistically significantly associated with any specific breast cancer subgroup. Older age at first childbirth (>30) was associated with a slightly increased risk of breast cancer (1.39: 0.94–2.07). There was a statistically significant association between late first childbirth and lobular type (2.51: 1.01–6.28), grade III tumours (2.67: 1.19–6.02), high levels of cyclin D1 (2.69: 1.18–6.12) and low levels of p27 (2.23: 1.15–4.35). We conclude that nulliparity and late first childbirth are associated with relatively more aggressive breast cancer subgroups. © 2009 UICC

“…In regions where registration is mandatory, but where births and deaths are not always registered, responses to surveys may depend on whether or not the vital events were officially registered. A study conducted in a remote Caribbean island, where careful historical census records had been maintained, reported that mothers are able to recall numbers of births and deaths accurately 10 . Most previous validation studies have compared maternal interviews with hospital records of vital events.…”

Reliability of maternal recall and reporting of child births and deaths in rural Egypt

Demographic indicators such as fertility rates and infant mortality rates are often measured in census surveys by interviewing mothers to obtain their pregnancy histories and child deaths. The validity of such surveys depends upon accurate recall of histories, truthful reporting of events and understanding of the questions posed. To measure the reliability of maternal reporting, two census surveys conducted in a rural Egyptian population were compared. Women between 15 and 55 years of age residing in 20 villages were asked their histories of live births, stillbirths and child deaths. An identical set of questions was posed 2 years later. Twice-monthly home visits were conducted in the intervening 2-year interval to identify accurately any new births, stillbirths and deaths occurring in the population. The maternal reports from the first census were combined with the prospectively identified births, stillbirths and deaths and compared with the maternal reports from the second census. For 1502 women, the discrepancies in the total number of births, stillbirths and child deaths reported between the two surveys were 0.6%, 4% and 0.6% respectively. However, when the consistency of responses was analysed, the proportion of women with discordant responses was 10%, 6% and 7% for the same measures. These results suggest that, despite the large number of births and deaths that women may experience in developing countries, maternal interviews provide reliable responses that can be used to estimate mortality and fertility rates in settings where vital records are incomplete or unreliable.
