Health and Nutrition Transitions
• Nutrition: from under-nutrition and malnutrition to
over-nutrition
• Health: from infectious to chronic diseases
• Implications:
– Chronic diseases affect elderly more
– Unawareness of chronic illness by individuals
– The public health system is designed to handle infectious
diseases and not chronic diseases
– Low incomes: inadequate resources to handle the expensive
treatment of chronic illnesses

Data: Indonesia Family Life Survey
IFLS : a large-scale broad -based longitudinal survey of
households and individuals that not only collects a set of socioeconomic characteristics , but also physical health biomarkers
and self-reported health measures
Four waves of IFLS: IFLS1 (1993), IFLS2 (1997), IFLS3
(2000), IFLS4 (2007).
V ery low attrition rates: over 90% of HHs from 1993 found in
2007, 88% of individuals
The paper will focus on markers and measures known to be
important for elderly health for which we have data for multiple
waves:
• Data available at http://www.rand.org/labor/FLS/IFLS
• Paper is RAND Labor and Population working paper WR-704

Health status-SES gradients
• SES variables: education, log per capita expenditure
•In this analysis is not causal!
•Omitted variables:
•For instance childhood health which can affect
completed schooling and adult income
•Reverse causality from health to income
•Can show health status differentials by SES
Impact of Respondent Schooling and
Household Per Capita Expenditure
• Have data on household PCE-better measure of longrun resources than current income
• Regress health outcomes for those 45+ in each wave
(1993, 1997, 2000, 2007) on health measures-pooled
regression for measures collected in multiple waves
• Covariates include:
– dummies for level of schooling
– linear spline in log PCE (around median)
– dummies for respondent age
– dummies for location (province/rural-urban) at
survey, year and interaction of year/location
dummies

Variables:
Source: IFLS4
Impact of Parental Health and Schooling
• Have measures of mother and father schooling and
health
• Health measures:
– Mother/father dead at 2007 (about 5% of sample parents
still alive)
– Mother/father in poor health at time of 2007 survey or just
prior to death, if dead
– Mother/father has difficulties with ADLs at time of 2007
survey or just prior to death, if dead
•
Regress health outcomes for those 50+ in 2007
on these measures, plus dummies for level of
parental schooling, plus dummies for respondent
age, plus dummies for province/rural-urban
location at birth
• Then regress changes 2007-1993 or 2007-1997 on same vars
