Gold Mining =

Mercury Pollution =

Contaminated water =

 Diarrhea?

 U5MR?

specific questions
SPECIFIC QUESTIONS

Is water being used by indigenous people and maroons polluted by the mercury used in gold-mining?

Is there an increase in the incidence of diarrhea in children < 5 in the period after the scale up of gold-mining compared to the period prior?

Is there a difference between incidence of diarrhea in children < 5 in villages in gold-mining areas with incidence in matching villages in other areas?

Is there an increase in the < 5 child mortality rate with diarrhea as the underlying cause?

study population
STUDY POPULATION

Small populations

Geographically contained

design
DESIGN

I. O1 O2 X O3 O4

a) Kwakoegron - series

b) Bigi Poika - series

II. O1 X O2

O3 O4

a)Kwakoegron & Makakriki - control

b) Bigi Poika & Carolina - control

X= scale up of gold mining

data collection
DATA COLLECTION

HHS (questionnaire): females of childbearing age

Routine data (checklists/compilation sheet) from civil services bureau (vital registry)

Routine data (checklists/compilation sheet) from health care facilities:

- admission/discharge (incl. transfer)

- patient charts

** Direct Observation (QC)

indicators
INDICATORS

# of cases of diarrhea reported by interviewees

# of deaths related to diarrhea reported by interviewees

# of children under 5 admitted to local Medical Mission post with diarrhea

# of children under 5 admitted to Academisch Ziekenhuis with diarrhea

# of deaths in children under 5 as a result of diarrhea (either while at MM or at AZ)

presenting the data
PRESENTING THE DATA

Note: Gold Bar represents gold mining activity scale up

Blue Bar represents “flood of 2006”

limitations issues
LIMITATIONS/ISSUES
  • Confounding variables: other risk factors for diarrhea
  • Other advershe health effects of mercury not researched
limitations issues continued
LIMITATIONS/ISSUES(continued)
  • Of all villages only Kwakoegron has actually requested assistance with this issue.
  • Fictitious data used due to time limitations and outdated info.
  • For “actual research” more lead time needed to identify appropriate villages as target populations.
dissemination policy impact
DISSEMINATION/POLICY IMPACT
  • Research findings to be shared with stakeholders.
  • Depending on outcome village leaders may have more evidence to request interventions to address unsafe goldmining practices/contamination of water.
dissemination policy impact continued
DISSEMINATION/POLICY IMPACT(continued)
  • Possible interventions to be discussed with village leaders --potential for follow up research to assess whether interventions actually work and health of indigenous and maroon children improves.
