A pioneering study led by Boston College researchers has found that personal networks in India could play a pivotal role in the adoption of cleaner cooking fuel, which would represent a significant step toward improving global public health.

鈥淭his is the first report to show that just like with tobacco use, obesity, or physical activity鈥攚here our networks play a role in shaping our behaviors and decisions鈥攑ersonal networks are also associated with what kinds of stoves rural poor use,鈥� said 糖心vlog直播平台 Assistant Professor of Social Work Praveen Kumar, coauthor of the new report, which was published in Environmental Research Letters.

In rural India, particularly among those living in poverty, people rely widely on solid fuels such as firewood, charcoal, animal dung, and crop residue for cooking. It has been estimated that household air pollution, to which indoor cooking contributes, accounted for roughly 600,000 premature deaths in India in 2019, making it a leading cause of preventable deaths in the nation of 1.4 billion residents. That鈥檚 why health officials have worked for decades to try to shift people to cleaner fuel sources, such as liquefied petroleum gas. But progress has been slow, due to economic, educational, and demographic barriers.

For the recent study, researchers queried 198 respondents from roughly thirty villages in the southern Indian state of Andhra Pradesh. They found that the more peers and friends a respondent has who use cleaner cooking technology, the more likely the respondent is to also use cleaner cooking technology鈥攁nd vice versa, Kumar said.

The study鈥檚 coauthors include Boston College School of Social Work Dean Gautam Yadama, as well as researchers from Harvard Medical School, Ohio State University, Chile鈥檚 Universidad Mayor, and Washington University, St. Louis. Their findings have implications for policymakers seeking ways to continue to convince poor households to shift to cleaner cooking fuels. 鈥淚f personal networks are so important,鈥� Kumar said, 鈥渢here is a need to find residents who are influencers or opinion leaders and build targeted awareness campaigns involving them.鈥�

Subsequent research should explore the threshold of personal networks with cleaner stoves that could shift households to cleaner cooking, Kumar said. 鈥淭he transition from traditional cooking to clean cooking is critically important鈥攏ot just in India,鈥� he said. 鈥淭his is a global public health problem.鈥澨�
