Hypothesis

Do folate deficiency, hyperhomocysteinemia, and low urinary creatinine increase the risk of arsenic-induced skin lesions among Bangladeshi adults?

Conclusion

Folate deficiency, hyperhomocysteinemia, and low urinary creatinine are risk factors for arsenic-induced skin lesions.

Supporting Evidence

  • Individuals with low folate had a 1.8 times higher risk of skin lesions.
  • Hyperhomocysteinemia increased the odds of skin lesions by 1.7 times.
  • Low urinary creatinine was associated with a 0.4-fold decrease in the odds of skin lesions.

Takeaway

If you don't have enough folate or have high levels of homocysteine, you might be more likely to get skin problems from arsenic in water.

Methodology

A nested case-control study was conducted with 274 cases of skin lesions and 274 matched controls based on sex, age, and water arsenic levels.

Potential Biases

Potential biases may arise from matching controls and cases based on limited criteria.

Limitations

The study may not account for all potential confounding factors and relies on self-reported data for some variables.

Participant Demographics

Participants were Bangladeshi adults aged 18-65, with a mix of genders and socioeconomic backgrounds.
