Q

What info do we gain from mortality figures on disease?

A

LIFE EXPECTANCY
death rates across ages

AGE-SPECIFIC MORTALITY RATE
death rates within specific ranges e.g. neonate, infant, 60+, adult

MATERNAL MORTALITY RATIO
mothers who die during childbirth

CAUSE-SPECIFIC DEATH RATES
e.g. HIV, TB etc

Q

What is ‘healthy life expectancy (HALE) at birth’?

A

combo of mortality and morbidity together

= average number of years that a person can expect to live in ‘FULL HEALTH’

Takes into account years lives in < full health due to disease and/or injury

Q

What is the global pattern for HALE?

A

HALE = healthy life expectancy (HALE) at birth

Greater difference between HALE and life expectancy in MEDCs than in LEDCs

= in MEDCs, older age, but this comes with a lower QoL at the end years

Q

What is the global pattern of mortality at different ages?

A

1/3 of deaths 0-29y

1/3 of deaths at 30-69y

MEDCs: deaths mainly in older adults

LEDCs: deaths mainly in children, adults and mothers

  • AIDS
  • TB
    [and neglected tropical diseases]
20
Q

A

higher in low income, low life expectancy countries

21
Q

What are the IMMEDIATE causes of death for 15-60y?

A

usually a combo of:

24
Q

What is maternal mortality?

A

death of a woman while pregnant or within 42 days of birth, from causes related to pregnancy or its management

25
Q

How is maternal mortality assessed?

A

MATERNAL MORTALITY RATIO

= number of maternal deaths per 100,000 live births

26
Q

Where is the risk of maternal mortality highest globally?

A
  • SubS Africa
  • Oceania
  • S Asia
27
Q

What risk factors contribute to maternal death?

A
  • high maternal age
  • multiple pregnancies
  • poor nutrition
28
Q

What are the statistics for maternal death risk globally?

A

high income countries
~ 1 : 3000

low income countries
~ 1 : 40

29
Q

What are the main IMMEDIATE causes of maternal mortality?

A
  • severe haemorrhage
  • abortion complications
  • eclampsia/high BP
  • maternal sepsis
  • obstructed labour
30
Q

What are the current trends in life expectancy?

A
  • life expectancy is rising
  • death rates falling (esp. in young from infectious disease)
  • low life expectancy, low income countries still vulnerable to infectious disease and other chronic infections
  • growing numbers of deaths due to chronic, non-infectious disease (even in low and middle income countries)
31

  • high BM
32
Q

What are the key UNDERLYING causes of death and disability in SubS Africa?

A
  • underweight child
  • indoor air pollution
  • suboptimal breastfeeding
  • iron deficiency
  • high BP
33
Q

What factors contribute to the relationship between income and life expectancy?

A

Low income related to:

  • inadequate nutrition
  • inadequate sanitation/water
  • inadequate housing
  • poor educational prospects
  • conflict/war
  • difficulty overcoming ecological hazards
34
Q

What are the major types of undernutrition?

A

(v. important in low income countries)

  • protein-energy malnutrition
  • Iodine deficiency
  • Iron deficiency
  • Zn deficiency
  • Vit A deficiency
35
Q

What are the consequences of undernutrition?

A
  • susceptibility ot infection (esp. infancy and early childhood)
  • limits growth (stunting)
  • increases pregnancy risk
36
Q

What are the risks in pregnancy associated with undernutrition?

A
  • Stunting increases risk of complicated labour

- increases risk of maternal haemorrhage and infection

37
Q

What diseases does unsafe water increase risk of?

A
  • cholera
  • typhoid
  • giardiasis
38
Q

Which health care deficiencies are present in low income countries?

A

LACKING:

  • immunisation programmes
  • maternal medical care
  • child health
  • HIV/AIDS treatment programmes
  • medication costs not met by health services
39
Q

A

HIGH SATURATED FAT
coronary heart disease

HIGH SALT
high BP

HIGH ENERGY (compared to expenditure)
Obesity, T2DM
40
Q

What is the link between tobacco and mortality?

A

= most readily preventable modern cause of premature death and disease

  • cancers
  • CHD
  • stroke

now declining in high income countries

41
Q

What are the main consequences of physical inactivity?

A
  • obesity
  • T2DM
  • CHD
  • Stroke
  • Cancers (colon, breast, endometrium, prostate)
42
Q
