Child labor and severe functioning difficulties and disability in Mexican children and adolescents 5-17 years of age

Inequities in birth registration, violent discipline, and child labour by disability status and sex: Evidence from the Multiple Indicator Cluster Surveys in 24 countries

Nearly 240 million children are estimated to have a disability globally. We describe inequities by disability status and sex in birth registration, child labour, and violent discipline outcomes. Data come from Round 6 of the Multiple Indicator Cluster Survey programme and includes 323,436 children, aged 2-17 years in 24 countries. We estimated non-registration of birth, child labour, and violent discipline, stratified by sex and disability in each country. We estimated age-adjusted prevalence ratios and prevalence differences, accounting for survey design, to calculate inequities by disability. There was large variation across countries in the percentage of children with disabilities (range: 4% to 28%), in non-registration (range: 0% to73%), child labour (range: 2% to 40%), and violent discipline (range: 48% to 95%). We found relative inequities by disability in birth registration in two countries among girls and one country among boys, and in birth certification in two countries among girls and among boys. Child labour was higher among girls with disabilities in two countries and among boys in three countries. We found larger and more prevalent inequities by disability in hazardous labour in six countries among girls (aPR range: 1.23 to 1.95) and in seven countries among boys (aPR range: 1.24 to 1.80). Inequities in the prevalence of violent discipline by disability were significant in four countries among girls (aPR range: 1.02 to 1.18) and among boys (aPRs: 1.02 to 1.15) and we found inequities in severe punishment nine countries among girls (aPR range: 1.12 to 2.27) and in 13 countries among boys (aPRs: 1.13 to 1.95). Context specific research is needed to understand the large variations in inequities by disability status and sex within and across countries. Monitoring inequities in child rights by disability status and sex is important to achieve the SDGs and ensure child protection programs reduce inequities.

Youth with disabilities are more likely than their peers to engage in hazardous child labour

BACKGROUND

Little is known about the extent to which children and adolescents with disabilities are exposed to child labour.

OBJECTIVE

To estimate prevalence rates and adjusted rate ratios of exposure to child labour among children and adolescents with/without disability in middle- and low-income countries and to determine whether these rates vary between functional limitations associated with disability.

PARTICIPANTS AND SETTING

Nationally representative samples involving 142,499 children aged 5-14 from 15 countries.

METHODS

Secondary analysis of data collected in UNICEF's Multiple Indicator Cluster Surveys.

RESULTS

Overall children and youth with disability were not at significantly greater risk of exposure than children without disability to child labour when demographic and contextual factors were taken into account. However, children and youth with disability were at significantly greater risk of exposure than children without disability to hazardous child labour (adjusted relative risk [ARR] = 1.15 [1.10-1.21], P < 0.001). Specifically, children and youth with impairments related to poorer mental health or cognitive functioning were at significantly greater risk of exposure to hazardous child labour (e.g., ARR for learning impairment = 1.27 [1.14-1.42], P < 0.001). In contrast, children with impairments related to sensory functioning, mobility and expressive communication were at no greater risk of exposure than children with no disability.

CONCLUSIONS

Children and youth with disability are at greater risk of exposure to hazardous child labour than children with no disability in middle- and low-income countries. Responses to eradicate hazardous child labour need to take account of the situation of children and youth with disability.

Evaluation of Benzene Exposure and Early Biomarkers of Kidney Damage in Children Exposed to Solvents Due to Precarious Work in Ticul, Yucatán, México

BACKGROUND

The child labor situation has been associated with precarious job conditions and poor health conditions because children are often exposed to unsafe work environments, stressful psycho-social work conditions, scarce or no access to protective services, and heavy work burdens.

OBJECTIVE

The aim of the study was to evaluate markers of exposure to benzene through the exposure biomarker trans, trans-muconic acid (tt-MA), and biomarkers of early renal damage in children who work in sites that are under precarious job conditions.

METHOD

Samples of urine were obtained from children (aged 6-12 years old) who resided in Ticul, Yucatan, Mexico. Exposure to benzene was assessed through trans, trans-muconic acid (t,t-MA). Evaluated renal damage biomarkers were: Cystatin-C (Cys-C), Osteopontin (OPN), α1-Microglobulin (α1-MG) and Neutrophil Gelatinase-Associated Lipocalin (NGAL).

FINDINGS

Children who live where the workplace is inside the dwelling presented higher mean levels of tt-MA (0.59 mg/g creatinine) compared with those who live away from the workshops (0.19 mg/g creatinine). Likewise, mean levels of NGAL (4.7, 5.2 ng/ml), albuminuria (10, 10 ng/ml), Cys-C (11.8, 7.5 ng/ml), OPN (224.4, 226.5 ng/ml) and α1-MG (96.6, 73.6 ng/ml) were found in children where the workplace was inside the dwelling and outside, respectively.

CONCLUSION

Our data indicate that the children who work under precarious job conditions are exposed to benzene, and they exhibit protein levels that suggest renal damage in a population in precarious working conditions. Therefore, the child population should be considered as the most vulnerable and susceptible to suffer adverse health effects.
