Using kerosene, wood for cooking ups cataract risk by 50% in women

Women who use wood, crop residues, kerosene and dried dung as fuel for cooking are about 50% more likely to have cataracts than those who do not, warns a new research.

Women who use wood, crop residues, kerosene and dried dung as fuel for cooking are about 50% more likely to have cataracts than those who do not, warns a new research.

The study was conducted by the All India Institute for Medical Sciences (AIIMS), Aravind Eye Hospitals and London School of Hygiene & Tropical Medicine.

“Our results reinforce the documented risks of biomass fuels on other health conditions in India and highlight the need for the rapid development of affordable, clean cooking fuels,” said study co-author RD Ravindran, the chairman of the Aravind Eye Care System.

The population-based study involved nearly 6,000 people aged 60 and over from randomly chosen rural villages and small towns in India.

Participants were interviewed at home on their use of cooking fuel over their adult life, and on a range of socioeconomic and lifestyle factors.

After taking into account other risk factors including indicators of poor nutrition, sun exposure, smoking and chewing tobacco, the researchers found that women who cooked with biomass fuels were 46 percent more likely to have nuclear cataracts compared to those who used gas.

Furthermore, the researchers found that the longer the women had been using biomass fuels, the greater was the risk of them getting cataracts — 50% more likely for 20 years use and 90 percent after 30 years.

“Our study provides the strongest evidence yet of an association with adult lifetime exposure to biomass fuels and cataracts,” professor Astrid Fletcher from the London School of Hygiene & Tropical Medicine who co-ordinated the study said.

“This was only found in women, probably because cooking was almost only done by women using stoves without chimneys, exposing them directly to smoke from burning biomass fuels. Unexpectedly we also found that women who cooked with kerosene were more likely to have cataracts,” Fletcher noted.

The study was published in the journal Environmental Health Perspectives.

Biomass cooking fuels are particularly common in India, especially in poorer communities, as they are generally cheap and easily accessible.

Recent estimates suggest that 83% of rural households and 19 percent of urban households in India use them. However, they are typically burnt in open stoves exposing households to high levels of health damaging pollutants including small respirable particulates.

It is thought these may impair the eye’s defence system, accelerating the clouding of the lens leading to cataract.
