Comparison of respiratory and skin disorders between residents living close to and far from Solous landfill site in Lagos State, Nigeria.

BACKGROUND

Solid waste dump sites have proven to have potentially high risk to human health as it serves as a source of air, soil and underground water pollution.

AIM: This study aimed to assess and compare the knowledge, respiratory disorders and skin disorders between residents living close to and far from landfill sites in Lagos State, Nigeria.

SETTING

Igando (a community within 5 km close to) and Badagry (a community beyond 5 km from) Solous Landfill sites in Lagos state, Nigeria.

METHODS

A comparative cross-sectional study amongst 103 respondents recruited from each of the two study sites by multistage sampling method was carried out. Data were collected using pretested, structured, interviewer-administered questionnaire, and analysed using Microsoft Excel 2007, EPI Info 7 and WinPepi statistical software packages. Student t-test, Fisher's exact and Chi-square tests were carried out. The p ≤ 0.05 was considered statistically significant.

RESULTS

The mean age of Igando and Badagry respondents was 34.18 ± 10.21 years and 32.62 ± 9.84 years, respectively. The two communities differed significantly (p 0.0001) with respect to distance of workplace from landfill site and duration of stay in the residential location. The mean knowledge score of respondents on respiratory and skin disorders associated with solid waste dump site close to landfill sites (82.53 ± 20.60) was statistically significantly higher than those of respondents far from landfill sites (71.84 ± 20.57) (p = 0.0003). Respiratory and skin disorders experiences of respondents close to landfill sites were statistically significantly (p 0.0001) higher than those of residents far from landfill sites with respect to wheezing, frequent sneezing, unpleasant odour, fever and skin rashes.

CONCLUSION

Respiratory and skin disorders experienced by respondents close to landfill sites are higher than those of residents far from landfill sites. Landfill sites should not be located close to human settlements.
