What they found
Studies in people
Use fell over time
The share of people reporting hydrogenated vegetable oil use dropped from 85.2% in 2006 to 55.7% in 2010. That is a 29.5% fall over the five years, averaging 5.9% per year.
Rural versus urban
People in rural areas were more likely to use hydrogenated vegetable oil than people in urban areas.
Money and education
Poorer people and people with less education were more likely to use hydrogenated vegetable oil than richer or college-educated people.
Ethnic group
Sisstani people were more likely to use hydrogenated vegetable oil than Fars-native people.
What the authors conclude
“HVO consumption decreased during the 5-year study (2006 to 2010), but HVO is still used extensively in northern Iran.”
Also in their conclusions
- They say hydrogenated vegetable oil use decreased over the five years but is still used extensively in northern Iran.
- They call for preventive early intervention strategies aimed at uneducated and poor families, with an emphasis on the Sisstanish ethnic group.
- They say these efforts should increase awareness about the negative consequences of hydrogenated vegetable oil consumption.
How it was done
The authors wanted to see how hydrogenated vegetable oil use changed over time and which family factors were linked to it.
They surveyed 6497 people aged 15 to 65 in northern Iran, chosen by cluster random sampling, once a year from 2006 to 2010. Interviewers asked about sociodemographic factors and the type of cooking oil used.
What it can’t tell you
- We summarised it from the abstract only.
- This study asked people which oil they used. It did not measure anyone's health.
- It can show links between family factors and oil use, but it cannot prove those factors caused the choice.
