Outcomes

1

Klemera-Doubal biological age

upin humans1

1 study

  1. Solid fuels increase Klemera-Doubal biological age in humans (0.14 years (95% CI: 0.08, 0.19)).

    “Compared to consistent use of cleaner fuels, consistent solid fuel use and switching from cleaner to solid fuels were significantly associated with an acceleration of 0.14 (95 % CI: 0.08, 0.19)”

    Humanscompared to consistent use of cleaner fuels2011-2015n = 8,561

Dual sensory impairment

upin humans1OR 1.23

1 study

  1. Solid fuels raise the risk of dual sensory impairment in humans (OR = 1.23, 95%CI: 1.02-1.49).

    “The use of solid fuels at baseline (OR = 1.23, 95%CI: 1.02-1.49) was associated with a higher risk of DSI compared to the use of clean fuels.”

  1. Solid fuels raise the risk of dementia in humans (HR = 1.32, 95 % CI: 1.06, 1.64).

    “consistent use of solid fuels was significantly associated with an evaluated risk of dementia (HR = 1.32, 95 % CI: 1.06, 1.64).”

Angina

1 study

  1. Solid fuels raise the risk of angina in humans (aOR 1.15, 99% CI 1.09-1.20).

    “The odds of angina were higher among individuals living in households that used solid fuels for cooking (aOR = 1.15, 99% CI- 1.09-1.20)”
