This study assessed the interactions between income, nutritional status and intestinal parasitism in children in Brazil.
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.
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 (β = 0.145; p = 0.003), female gender (β = 0.117; p = 0.015), and infections with A. lumbricoides (β = - 0.141; p = 0.006) and Entamoeba coli (β = - 0.100; p = 0.043). Weight-for-age z scores are influenced by monthly per capita family income (β = 0.175; p < 0.001), female gender (β = 0.123; p = 0.010), and infections with A. lumbricoides (β = - 0.127; p = 0.012), and Entamoeba coli (β = - 0.101; p = 0.039). Monthly per capita family income (β = 0.102; p = 0.039) and female gender (β = 0.134; p = 0.007) positively influences mid upper arm circumpherence.
Intestinal parasitism and low family income negatively influence the physical development of children in low-income communities in different Brazilian regions.
本研究评估了巴西儿童中收入、营养状况和肠道寄生虫感染之间的相互关系。
这是一项横断面研究（n=421 名 1 至 14 岁的儿童，居住在皮奥伊州（特雷西纳市的农村社区）和里约热内卢州（卡舒埃拉斯-德-马卡库市的农村和城郊社区），目的是获得收入和人体测量数据，以及通过里奇技术进行粪便样本寄生虫分析。
感染蛔虫的儿童身高年龄 z 评分（-1.36±0.75 与-0.11±1.02；p<0.001）、体重年龄 z 评分（-1.23±0.74 与 0.09±1.15；p=0.001）和体重身高 z 评分（-0.68±0.44 与 0.23±1.25；p=0.006）明显低于未感染儿童。钩虫感染也与较低的身高年龄 z 评分（-1.08±1.17 与-0.12±1.02；p=0.015）和体重年龄 z 评分（-1.03±1.13 与 0.08±1.15；p=0.012）相关。感染结肠内阿米巴的儿童身高年龄 z 评分（-0.54±1.02 与-0.09±1.02；p=0.005）和体重年龄 z 评分（-0.44±1.15 与 0.12±1.15；p=0.002）明显较低。多元线性回归分析显示，身高年龄 z 评分受家庭人均月收入（β=0.145；p=0.003）、女性性别（β=0.117；p=0.015）和感染蛔虫（β=-0.141；p=0.006）和结肠内阿米巴（β=-0.100；p=0.043）的独立影响。体重年龄 z 评分受家庭人均月收入（β=0.175；p<0.001）、女性性别（β=0.123；p=0.010）、感染蛔虫（β=-0.127；p=0.012）和结肠内阿米巴（β=-0.101；p=0.039）的影响。家庭人均月收入（β=0.102；p=0.039）和女性性别（β=0.134；p=0.007）对中上臂围度有积极影响。
肠道寄生虫感染和低家庭收入对巴西不同地区低收入社区儿童的身体发育有负面影响。
