Could biomass fuel use perpetuate the poverty trap through cardiovascular disease and all-cause mortality?

Shuyi Qiu and John S Ji

Many people around the world are still using biomass as a fuel for cooking and heating. Inefficient combustion of solid fuels is the primary cause of indoor household air pollution, estimated to be responsible for 4.3 million premature deaths in 2012 (7.7% of total mortality).

The World Health Organization’s latest global air quality guidelines point out that indoor air pollution causes a health burden that mostly affects people in low- and middle-income countries. Many global development agencies are working with governments of developing countries to reduce household air pollution. For example, China’s Relocation Program in the poorest provinces is a significant part of China’s poverty eradication plans. This large-scale program relocates millions of residents in absolute poverty to places with better living conditions, including fuel type.

How has cardiovascular disease contributed to the rural–urban life expectancy gap?

Leah Abrams

In the United States, rural residents do not live as long as their urban counterparts. This disparity has been widening for decades. Around 1970, urban life expectancy was 70.9 years, compared with 70.5 in rural areas, but by 2005–2009, the difference was greater (78.8 versus 76.8 years). In our research recently published in the IJE, we found that the gap in life expectancy would be even wider today if declines in cardiovascular disease (CVD) mortality had not dramatically slowed around 2010.

“Not-so-good-anymore” cholesterol linked to vision loss in the elderly

Only a few years ago, doctors would advise their patients that elevated blood levels of high-density lipoprotein cholesterol (HDL-C), then termed the “good cholesterol”, were beneficial and would protect them against coronary heart disease. This belief has been called into question, however, as neither genetics nor clinical trials could demonstrate that raising HDL-C levels would protect against cardiovascular disease. Our study, published recently in the IJE, casts further doubt on this “not-so-good-anymore” cholesterol by showing that genetic variants that cause higher HDL-C levels also increase the risk for age-related macular degeneration (AMD).
