Example of socioeconomic inequalities in STH: parental education and ascariasis infection in a rural community in Osun State, Nigeria (2005–2006) [71].

<p>A total of 440 children <16 years of age from randomly selected households were included. Information on parental education was collected through a questionnaire, and faecal samples were examined for the presence of <i>Ascaris</i> eggs. The prevalence of ascariasis was statistically significantly higher among children of parents without a primary education (<i>p</i> < 0.001).</p

Example of socioeconomic inequalities in schistosomiasis: association between <i>S</i>. <i>mansoni</i> prevalence (%) and educational attainment of household head in the town of Man, western Côte d’Ivoire (2004–2005) [30].

<p>The study was conducted in urban farming communities in the town of Man, western Côte d’Ivoire. A total of 113 farming households (586 individuals from all ages) and 21 nonfarming households (130 individuals from all ages) from six agricultural zones were interviewed, and stool samples were examined for <i>S</i>. <i>mansoni</i>. Infection prevalence was 51.4% in farming households and 44.6% in nonfarming households. Lower educational attainment was associated with higher infection prevalence in farming households (<i>p</i> = 0.008) but not in nonfarming households. Infection prevalence was higher in poorer households but not statistically significantly so.</p

Number of papers reporting greater odds of infection among lower socioeconomic strata than among higher socioeconomic strata, number of papers reporting mixed results, and number of papers reporting no inequality or a reverse association, 2004–2013.

<p><i>Inequality</i>: Statistically significant (<i>p</i> < 0.05) inequality in NTD distribution, with greater odds of infection among lower socioeconomic strata. This also includes papers reporting statistically significant inequality for one SEP indicator and nonsignificant inequality of at least 50% greater odds of infection among lower strata for another SEP indicator. The same criterion was used for socioeconomic inequality in NTD prevalence in one age group and not in another age group and for one NTD outcome measure and not for another NTD outcome measure. <i>Mixed</i>: Studies reporting a combination of statistically significant inequality—with greater odds of infection among lower socioeconomic strata—for one SEP indicator, age group, or NTD outcome measure and no such inequality (or reversed pattern) for another SEP indicator, age group, or NTD outcome measure. <i>No inequality</i>: Studies reporting no substantial and statistically significantly greater odds of infection among lower socioeconomic strata or reporting a reverse pattern, with greater odds of infection among higher strata. Of the 93 publications included in the review, two studies (Balen et al. 2011 and Steinmann et al. Acta Tropica 2007) reported findings for both schistosomiasis and STH separately. In the figure, we included these studies under both schistosomisasis and STH. Two other studies that reported on combined schistosomiasis and STH infection in the same individuals were not included in this figure (one reported inequality, the other no inequality).</p
