RESUMO

BACKGROUND: This study assessed the interactions between income, nutritional status and intestinal parasitism in children in Brazil. METHODS: A cross-sectional study (n = 421 children aged 1 to 14 years living in the states of Piauí (rural communities in the city of Teresina) and Rio de Janeiro (rural and periurban communities in the city of Cachoeiras de Macacu) was performed in order to obtain income and anthropometric data, as well as fecal samples for parasitological analyses through the Ritchie technique. RESULTS: Children infected with Ascaris lumbricoides had significantly lower means of height-for-age z scores (- 1.36 ± 0.75 vs. - 0.11 ± 1.02; p < 0.001), weight-for-age z scores (- 1.23 ± 0.74 vs. 0.09 ± 1.15; p = 0.001), and weight-for-height z scores (- 0.68 ± 0.44 vs. 0.23 ± 1.25; p = 0.006) when compared with uninfected children. Infection with hookworm was also associated with lower means of height-for-age z scores (- 1.08 ± 1.17 vs. - 0.12 ± 1.02; p = 0.015) and weight-for-age z scores (- 1.03 ± 1.13 vs. 0.08 ± 1.15; p = 0.012). Children infected with Entamoeba coli presented significantly lower means of height-for-age z scores (- 0.54 ± 1.02 vs. - 0.09 ± 1.02; p = 0.005) and weight-for-age z scores (- 0.44 ± 1.15 vs. 0.12 ± 1.15; p = 0.002). The multivariate multiple linear regression analysis showed that height-for-age z scores are independently influenced by monthly per capita family income (ß = 0.145; p = 0.003), female gender (ß = 0.117; p = 0.015), and infections with A. lumbricoides (ß = - 0.141; p = 0.006) and Entamoeba coli (ß = - 0.100; p = 0.043). Weight-for-age z scores are influenced by monthly per capita family income (ß = 0.175; p < 0.001), female gender (ß = 0.123; p = 0.010), and infections with A. lumbricoides (ß = - 0.127; p = 0.012), and Entamoeba coli (ß = - 0.101; p = 0.039). Monthly per capita family income (ß = 0.102; p = 0.039) and female gender (ß = 0.134; p = 0.007) positively influences mid upper arm circumpherence. CONCLUSIONS: Intestinal parasitism and low family income negatively influence the physical development of children in low-income communities in different Brazilian regions.

RESUMO

This study aims to assess the prevalence, distribution, and etiological profile of intestinal parasitism in children living in periurban areas in Cachoeiras de Macacu, Rio de Janeiro, Brazil. A community-based cross-sectional survey (n = 479) was carried out. Prevalence of infection with G. duodenalis and E. histolytica/E. dispar was 8.6% (n = 41) and 13.4% (n = 64), respectively. Infection with G. duodenalis was significantly more frequent among children living in poor families (24/187 (12.8%) vs. 16/272 (5.9%); prevalence ratio (PR) = 2.18; 95% confidence interval (CI) = 1.19-3.99; p=0.011). This difference was also significant for infection with any pathogenic parasite (43/187 (23%) vs. 40/272 (14/7%); PR = 1.56; 95% CI = 1.06-2.30; p=0.026). In addition, people residing in houses with more than four inhabitants showed significantly higher positivity for infections with G. duodenalis and with E. histolytica/E. dispar (22/138 (15.9%) vs. 16/311 (5.1%); PR = 3.09; 95% CI = 1.68-5.71; p < 0.001 for G. duodenalis and 32/138 (23.2%) vs. 30/311 (9.6%); PR = 2.40; 95% CI = 1.52-3.79; p < 0.001 for E. histolytica/E. dispar). Laboratory diagnosis of protozoan enteric infections and effective drugs for their treatment are unmet goals in the primary health care system. Therefore, giardiasis and amebiasis are neglected conditions.
