Title: Measurement 8
1Measurement 8 9
2Health indicators
- Health risks
- Nutrition Water / Sanitation Tobacco, Alcohol
consumption - Morbidity / Health status
- Incidence (new cases flows) Prevalence
(infectionstocks) - ex. HIV seropositivity
-
- Direct measurement (vision, audition,
respiration, blood test) - Symptoms (absent from work for sickness, often
feels crying...) - Self-declaration been sick in the past 15 days?
? seen a doctor? - Mortality
- Infant Neonatal (1st month of life)
Postnatal (1st year of life) 1q0 - Under-five Infant Child 4q0
- Adult mortality (between 15 and 60)
- Life expectancy
- Mortality by causes of death
3Health systems and health policy
- Public and private expenditures
- Prevention (health risks) treatment
- Insurance
- Number of dispensaries, of hospital beds
- Number of physicians, nurses
- Availability and price of medicines
- Vaccination rates
4Correlates of Health
- Correlates
- Individual genetic predispositions
- Social background, education, income
- Ex1 Life expectancy according to occupation
- (around 10 years of diff. between a university
teacher and an unskilled worker) - Ex2 Children height stature inequality between
and within countries
5Equity (1)
- Outcome f(C,P)R
- C circumstances PPolicy Rresponsibility
- P ex-ante intervention or ex-post compensation
- 2 principles of equality of opportunity
- Natural reward P should let R its impact
- Compensation P should equalize f(C,P)
- Ex. Expenditures for cancer or AIDS
- C social origin (e.g. white/blue-collar,
white/black...) - R individual behavior (ex. smoking, sex)
- P public subsidy (cure of cancer, tri-therapy)
6Equity (2)
Rows Social origin Cols Risk level within
each social origin Cells Costs of treat-ment
7Nutrition
- Nutritional intakes quantity of food,
subsistence basket (see Roman example) quality
of food - Nutritional outcomes height, weight
8What does height reflect?
Individual stature genetics - exposure to
infectious pathogens nutrition during
growth Mean group stature genetics 0 ? !
Differential mortality exposure to
pathogens nutrition Weight, Quételet index (or
BMI) more short-term ? obesity, anorexia
9When is height determined?
Children growth timing In utero (ex.
phylloxera) From 0 to 2 From 2 to 5
Stabilization period During puberty
10Height and income
- Not much correlated with income
- Differential mortality
- Quantity and quality of calories
- Quality of the diet
- Causality
- Height and future wages
- Parental income and height (ex. Cocoa crisis in
Côte dIvoire, phylloxera in France)
11Tall Africans, Small Indians

14HIV/AIDS
15HIV/AIDS Epidemics
- Epidemiology and prevention
- Still not very well-known epidemics
- Heterosexual and a more feminine
- The epidemics is in fact rather evenly
distributed at high incidence rates - Strong sensitivity with respect to safe behavior
- Large fall of life expectancy and of population
growth - Orphans
- Costly medecine
- Opportunistic infections around 360 (2000
prices) /year /adult - HAART (Tri-Therapies) around 1000
- Mother-baby transmission
-
- Economic impact 5 main channels
- Medium-term
- Labor supply (dependence ratio, skill
composition) ?household information - Illness and labor productivity ?work
participation information - Enterprises and administrations disorganization ?
specific surveys - Long-term
16HIV/AIDS Prevalence Measurement
- Pre-natal visits ? blood test
- ? Bias to be corrected not all women go to a
pre-natal visit (80 women in Cote dIvoire) a
sample of pre-natal visits is not a sample of
women seropositivity of men remains unknown - Population surveys
- ? Saliva tests or blood tests?
17Morbidity self-declaration bias
- Cote dIvoire 2-5 years old children
- Sick in the 15 days preceding the interview
- 1988 16 if cons.per cap.ltmedian, 17 otherwise
- 1993 idem, 10 vs. 11
- Often encountered spurious correlation child
care and preference attrition - Cocoa producers compared to other farmers
- Cocoa p. wealthier by 20 in 1988, but at par in
1993 - 1988 19 sick in other farmers vs. 11 in cocoa
producing households - 1993 11 other farmers, 10 cocoa producers
- Double difference (10-11)-(11-19)7
- Wald estimator 7/-20 0.35 income elasticity
18Mortality
- Mortality rates
- 1q0 Cohort of born in t jan.dec. ? dead in
t1 jd - 4q1 Cohort of survivors in t1 j.d. ? dead
between t4 and t5 - 4q0 1q0 (1-1q0)4q1
- 1qa proba of dying between age a and age a1
- tpa proba of surviving from age a to age at
(tpT 0) - Life expectancy at age h
- La St0,..,T t tpa tqt1 (tpT 0 1qT 1)
19Rome (1)
- Measure welfare in Rome in comparison with
- GDP? Rather impossible
- Height stature of skeletons? They burnt their
dead (except in Pompeii) - Unskilled laborers household purchasing power
- Wages and prices in denarii (? silver grams)
from the Diocletian edict (maximum prices for
inflation control) - Bare bone basket
