Mortality

DEFINITIONS

Mortality (general mortality ratio) – characterizes intensity of mortality in the whole. Mortality is calculated dividing number of deaths during the year by average number of population of the year. It is expressed per 1,000 populations usually.

Perinatal period – is time period from 22 completed weeks of pregnancy (154 days, when weight of foetus is 500g, usually) till 7 completed days after birth (6 days, 23 hours and 59 minutes).

Perinatal mortality – is number of stillborns and deaths during the first week life per 1,000 live and stillborns. Since 2017 fetocide cases (induced foetal death due to medical indications) are counted separately from stillbirths and these cases are not included in perinatal mortality.

Perinatal death – is death of foetus and newborn during perinatal period. Perinatal death includes dying of foetus before birth (from 154th day of pregnancy) and during birth (stillborn), and newborn dying during the first week of life (early neonatal death).

Stillbirth – is foetus born lifeless after 22 weeks of pregnancy (after 154 days, when weight of foetus is 500 g, usually). Death is confirmed with fact that foetus is not breezing after separating from mother and showing no evidence of life as heart activity, pulsation of umbilical cord or motion of muscles.

Antenatal death – is death of foetus before beginning of the childbirth.

Intranatal death – is death of foetus during the childbirth.

Neonatal death – is dying of live-born child during the time period from day 0 till 27th day of life (27 days, 23 hours, 59 minutes).

Early neonatal death – is dying of live-born child during the time period from day 0 till 6th day of life (6 days, 23 hours, 59 minutes).

Late neonatal death – is dying of live-born child during the time period from 7th till 27th day of life (27 days, 23 hours, 59 minutes).

Neonatal mortality – the number of deaths of live-born children under 28 days old per 1,000 live births.

Early neonatal mortality – the number of deaths of live-born children up to one week age per 1000 live births.

Infant death – is dying of live-born child during the first year of life (till age of 11 months and 30 days).

Infant mortality – is number live-born children died during the first year of life per 1000 life births.

Mother death – is death of female during pregnancy or 42 days after its ending irrespective of duration and localization of pregnancy due to reasons related with pregnancy or reasons that were aggravated by pregnancy or its management but not due to accidents or coincidences.

Maternal mortality – the numbers of death of a woman while pregnant, delivery or within 42 days after termination of pregnancy, irrespective of the duration and the site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management, but not from accidental or incidental causes per 100 000 of live births.

Direct obstetric deaths – direct obstetric deaths are those resulting from obstetric complications of the pregnant state (pregnancy, labour and puerperium), from interventions, omissions, incorrect treatment, or from a chain of events resulting from any of the above.

Indirect obstetric deaths – indirect obstetric deaths are those resulting from previous existing disease or disease that developed during pregnancy and which was not due to direct obstetric causes, but which was aggravated by physiologic effects of pregnancy.

Mean population per year – is arithmetical mean from numbers of population at the beginning and the end of the year.

Age – is number of complete years of life; for children under age of 1 year – number of months; for children under age of 1 month – number of days.

Causes of death – which are written in the Certificate about death are diseases, conditions or injuries caused or promoted death, and conditions of accident or violence that have caused such an injury.

Region – a territorial division in regions according to the Regulation (EC) No 1059/2003 of the European Parliament and of the Council of 26 May 2003 on the establishment of a common classification of territorial units for statistics (NUTS). NUTS classification is a hierarchical system for dividing up the economic territory of the EU for the purpose of the collection, development and harmonisation of EU regional statistics; socio-economic analyses of the regions (NUTS 1: major socio-economic regions, NUTS 2: basic regions for the application of regional policies, NUTS 3: as small regions for specific diagnoses); framing of EU regional policies. NUTS 3 applied in this yearbook. The list of administrative territories including in regions is available at: https://likumi.lv/doc.php?id=88074.

METHODOLOGY

Mortality rates are calculated per 100 000 average population over the period.The figures by age group and gender are calculated per 100 000 population of the respective age group and gender.

Mortality from Malignant neoplasm of cervix uteri (C53 according to International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10)), malignant neoplasm of corpus uteri (C54 according to ICD-10), malignant neoplasm of ovary (C56 according to ICD-10) and pregnancy, childbirth and the puerperium (O00-O99 according to ICD-10) ) was calculated only for the female population; mortality from malignant neoplasm of prostate (C61 according to ICD-10) per male population.
