Abstract

The current measures of cognitive functioning in adulthood do not indicate a long-term association with prenatal exposure to the Dutch famine. However, whether such association emerges in China is poorly understood.

We aimed to investigate the potential effect of prenatal exposure to the 1959–1961 Chinese famine on adult cognitive impairment. We obtained data from the Second National Sample Survey on Disability implemented in thirty-one provinces in 2006, and restricted our analysis to 387 093 individuals born in 1956–1965.

Cognitive impairment was defined as intelligence quotient (IQ) score under 70 and IQ of adults was evaluated by the Wechsler Adult Intelligence Scale – China Revision. Famine severity was defined as excess death rate. The famine impact on adult cognitive impairment was estimated by difference-in-difference models, established by examining the variations of famine exposure across birth cohorts.

Results show that compared with adults born in 1956–1958, those who were exposed to Chinese famine during gestation (born in 1959–1961) were at greater risk of cognitive impairment in the total sample. Stratified analyses showed that this effect was evident in males and females, but only in rural, not in urban areas.

In conclusion, prenatal exposure to famine had an enduring deleterious effect on risk of cognitive impairment in rural adults.

Hunger and malnutrition are not problems exclusive to low income countries.

That is why the international community cannot realise its ambitious international agenda of achieving zero hunger and malnutrition without a renewed focus on countries in economic transition where hunger and malnutrition remain.

The majority of the world’s hungry and malnourished population now live in Middle Income Countries (MICs).

For these countries to best fulfil their vital role in supporting zero hunger and malnutrition, they must promote effective country-led strategies that will reduce hunger and malnutrition at home.
