Abstract:

Objective:

To describe the characteristics of Mexican children and adolescents 5-17 years with severe functioning difficulties and disability and explore their participation in child labor.

Materials and methods:

Using data from the National Survey of Boys, Girls and Women in Mexico 2015 we estimated prevalence of functioning difficulties and disability and used logistic regression to explore the association between this condition and child labor.

Results:

While 11.2% of Mexicans 5-17 years-old has severe functioning difficulties or disability, 13.4% work. The functioning difficulty and disability domains with the highest prevalence are experiencing anxiety (5.4%) and depression (1.5%) daily. Children and adolescents with severe functioning difficulties and disability are 70% more likely to do child labor [OR=1.7, 95%CI:1.2,2.4]. Educational lag doubles the likelihood of doing child labor [OR=2.2, 95%CI:1.5,3.3].

Conclusions:

Guaranteeing educational opportunities and respect for the rights of children with severe functioning difficulties and disability is essential to achieve development of their full potential.

Introduction

An estimated 785 million people (15.6% of the total population) worldwide 15 years old or over live with some type of disability, of whom 110 millions have severe functioning difficulties. In addition, an estimated 95 million girls and boys have a functioning difficulty or disability, of whom 13 million have a severe disability.11. Organización Mundial de la Salud. Informe mundial sobre la discapacidad. Ginebra:OMS, 2011. In Mexico, the 2012 National Survey on Household Income and Expenses (ENIGH, using the Spanish acronym) estimated that approximately 564 000 children under 14 years old had difficulties carrying out daily activities.22. INEGI. Estadísticas a propósito del día del niño (30 de abril), 28 de abril de 2015. Aguascalientes, Ags: INEGI, 2015. Data from the 2014 National Survey on Demographic Dynamics (ENADID) estimated that 1.9% of minors under 18 years old in Mexico had a disability and 4.8% had a functional difficulty.33. INEGI. Estadísticas a propósito del día del niño (30 de abril), 27 de abril de 2016, Aguascalientes, Ags: INEGI, 2015.

In general the evidence has shown that people with a functioning difficulty or disability tend to live in households that compared to the average have greater poverty, less education, lower employment rates, poorer health and in general worse living conditions. Children with a functioning difficulty or disability in particular can experience a variety of disadvantages and types of exclusion, such as greater participation in child labor and reduced access to education and health services, all of which can have an impact on future opportunities and their potential in general.44.

However, there is a dearth of published or grey literature about the relationship between functioning difficulties or disabilities in children and child labor, including any possible associations with educational attainment. Such data is important for a variety of reasons; to begin with, child labor has been found to have a negative impact on children’s development6 as well as on health during childhood, adolescence and adulthood.66.

Moreover, child labor is recognized as a violation of children’s rights and can imply immediate and serious danger to children’s safety as well as curtail their education.44. UNICEF . Estado Mundial de la Infancia 2013. Niñas y niños con discapacidad. Ginebra: OMS, 2013.,99. Organización Internacional del Trabajo. Informe mundial de 2015 sobre el trabajo infantil: Allanar el camino hacia el trabajo decente para los jóvenes. Ginebra: OIT, 2015. Although the relationship between child labor and education is complex, child labor is often associated with inadequate educational opportunities and attainment;77. Roggero P, Mangiaterra V, Bustreo F, Rosati F. The health impact of child labor in developing countries: evidence from cross-country data.

in Latin America child labor has been found to result in lower test scores in mathematics and language.1010. Gunnarsson V, Orazem PF, Sánchez MA. Child labor and school achievement in Latin America. World Bank Econ Rev 2006;20(1):31-54. https://doi.org/10.1093/wber/lhj003
https://doi.org/10.1093/wber/lhj003...
In the specific case of children with a functioning difficulty or disability, they have fewer possibilities of starting or staying in school as compared to those without such difficulties or disability.11. Organización Mundial de la Salud. Informe mundial sobre la discapacidad. Ginebra:OMS, 2011. The issue of educational enrollment and attainment is of utmost importance given that research has found a causal impact of education on health and mortality.1111. Lleras-Muney A. The relationship between education and adult mortality in the United States. Rev Econ Stud 2005;72(1):189-221. https://doi.org/10.1111/0034-6527.00329
https://doi.org/10.1111/0034-6527.00329...
Since both lack of school enrollment and poverty are associated with child labor,77. Roggero P, Mangiaterra V, Bustreo F, Rosati F. The health impact of child labor in developing countries: evidence from cross-country data. Am J Public Health 2007;97(2):271-275. https://doi.org/10.2105/AJPH.2005.066829
https://doi.org/10.2105/AJPH.2005.066829...
there are worrisome indications of a vicious cycle of limited education and poverty for those who do child labor, perhaps especially for children who have a functioning difficulty or disability.55. Filmer D. Disability, poverty, and schooling in developing countries: Results from 14 Household Surveys. The World Bank Economic Review 2008;22:141-163. https://doi.org/10.1093/wber/lhm021
https://doi.org/10.1093/wber/lhm021...

Given the above, research exploring these relationships and associations are needed in order to position the issue of child labor (specifically among children with functioning difficulties or disabilities, and also among children in general) in the national and international political agenda and for developing related evidence-based policies (including laws and social programs). Such policies are important for two reasons. First, laws on compulsory school attendance and those limiting child labor can contribute to increased years of education and decreased educational inequality1212. Lleras-Muney A. Were Compulsory Attendance and Child Labor Laws effective? An Analysis from 1915 to 1939. J Law and Economics 2002;45(2):401-435. https://doi.org/10.1086/340393
https://doi.org/10.1086/340393...
(and given the cited causal impact of education on health and mortality, could thereby increase health and decrease early mortality). Second, that social policies such as poverty reduction programs have been found to increase educational attainment and decrease child labor.1313. Schultz TP. School Subsidies for the Poor: Evaluating the Mexican Progresa Poverty Program. J Development Economics 2004;74:199-250. https://doi.org/10.1016/j.jdeveco.2003.12.009

Data about general prevalence of functioning difficulty and disability among children and specifically on associations with child labor could be a first step in developing evidence-based policies aimed at guaranteeing these children’s rights and providing services.

The first objective of this article is to describe Mexican children and adolescents 5 to 17 years old who have severe functioning difficulties or disabilities, based on current information measured by an instrument developed by international experts. This description will provide context for our second objective, which is to measure the prevalence of child labor among children in this age group in Mexico and explore any associations with severe functioning difficulties or disabilities. In addition, we explore associations with educational lags. Our hypothesis is that children who do child labor will tend to have severe functioning difficulties or disabilities as well as an educational lag.

Materials and methods

We used data from the National Survey of Boys, Girls and Women in Mexico 2015. The Ethics Committee of the National Institute of Public Health of Mexico approved the survey research protocol, letters of consent and instruments. This was a probabilistic, multi-stage, cluster, household survey that is representative at the national and regional levels and for rural and urban areas. A detailed description of the survey methodology can be found elsewhere.1515. De Castro F, Rojas R, Villalobos A, Allen B, Hubert C, Romero M, et al. Bases metodológicas y resultados de la implementación de la Encuesta Nacional de Niños, Niñas y Mujeres en México 2015. Salud Publica Mex 2016;58(6):676-684. https://doi.org/10.21149/spm.v58i6.8192
https://doi.org/10.21149/spm.v58i6.8192...
The data used in this analysis were collected with two questionnaires: the first on household characteristics was applied to an adult member of the household; the second on functioning difficulties and disability of the child or adolescent was applied to the child’s or adolescent’s mother, except for emancipated adolescents (who live without a guardian) in which case they responded to the questionnaire themselves. The first questionnaire collected information about the household, including education levels for all members and child labor done by a randomly selected household member 5 to 17 years old. The second instrument included 40 questions that evaluate the type and level of functioning difficulties and disability in 14 domains; this questionnaire is based on the International Classification of Functioning, Disability and Health (ICF).1616. OMS/OPS. Clasificación Internacional del Funcionamiento, de la Discapacidad y de la Salud:CIF. Ginebra, Suiza: Organización Mundial de la Salud, 2001.

The initial data analysis explored prevalence of functioning difficulty and disability in general as well as within specific domains, among a representative sample of 11 607, 5-17 year-old Mexican children and adolescents. A subsample of 4 655 children and adolescents with information on child labor was then analyzed. Percentages and 95% confidence intervals (CI) were calculated, bivariate comparisons and Wald tests for independence1717. Lohr S. Muestreo: diseño y análisis. Ciudad de México: International Thompson, 2000. were done and a logistic regression model was constructed to test the associations between child labor and severe functioning difficulties and disabilities. Given the possibility that wealth index (socio-economic level) is strongly correlated to the other variables in the model (specifically child labor and educational lag), in the logistic regression model, we first analyzed the data adjusting by wealth index. Next we did the analysis eliminating wealth index from the model; the results obtained were extremely similar and we include the analysis that eliminates wealth index. Statistical analysis took into account the complex sample design, using the functioning difficulty and disability survey sample weight for analysis of this data and a scaled weight for analyzing the number of 5-17 year-olds for whom child labor data was collected. Analysis was done in Stata SE 12.1.

The main variables in this analysis were defined as follows:

Functioning difficulties and disability was defined as severe difficulties in functioning in at least one of the following domains: seeing, hearing, walking, feeding or dressing, being understood inside the home, being understood outside the home, learning, remembering, focusing, accepting change, making friends, controlling behavior, anxiety and depression. To generate the functioning difficulties and disability variable the questions on these domains were combined; greater detail about this variable can be found elsewhere in this issue.1818. Module on Child Functioning and Disability, Washington Group on Disability Statistics/UNICEF. Draft Document. Washington DC: WG, 2014 [accessed on: May 4, 2017]. Available at: https://www.cdc.gov/nchs/data/washington
https://www.cdc.gov/nchs/data/washington...

Socio-economic status was divided into three categories -low, middle and high; greater detail about the wealth index this was based on can be consulted elsewhere in this issue.1919. De Castro F, Hubert C, Strand E, Prado E, Braverman A. Severe functional difficulties and disabilities in children and adolescents and the Sustainable Development Goals. Salud Publica Mex 2017;59:354-360. https://doi.org/10.21149/8487
https://doi.org/10.21149/8487...

Educational lag assesses the progress of a student in the school system calculating schooling-for-age. We estimated years of completed schooling and we calculated the difference between schooling-for-age with the child’s actual age, and the normal age in a given grade (year in school). All differences higher than one are considered over-age students, which mean that their progress in the school system is below the normal performance because of grade repetition, late entry, or dropping out. In sum, educational lag indicates students over the normal age for the grade they are currently in.

Child labor was defined according to the MICS survey criteria, which are defined by UNICEF, are internationally comparable and are based on the International Labor Organization conventions.2020. Dayıoğlu M. Impact of Unpaid Household Services on the Measurement of Child Labour. MICS Methodological Papers, No. 2. New York: Statistics and Monitoring Section, Division of Policy and Strategy, United Nations Children’s Fund: 2013. Child labor is defined as carrying out housework above specified thresholds (any done by children under twelve, adolescents 12-14 years old who do 28 or more hours and adolescents 15-17 years old who do 43 or more hours per week), economic activity above the minimum specified number of hours for their age (an hour or more for children under twelve, 14 or more hours for adolescents 12-14 years old and 43 or more hours per week for adolescents 15-17 years old) or when the minor works in dangerous conditions.

Results

Socio-demographic and educational characteristics of children and adolescents with severe functioning difficulties and disability

Prevalence of severe functioning difficulties and disability in at least one domain is 11.2% among Mexican children and adolescents 5 to 17 years old and was higher in boys (12.7%, 95%CI 11.3,14.2) than in girls (9.7%, 95%CI 8.5,11.1) (table I). The domains with the highest prevalence are experiencing anxiety (5.5%, 95%CI 4.8,6.2) daily, having difficulty controlling behavior (5.2%, 95%CI 4.4,6.0) or experiencing depression (1.5%, 95%CI 1.2,1.9) daily. Difficulty controlling behavior was significantly greater among boys (6.9%, 95%CI 5.8,8.1) than girls (3.4%, 95%CI 2.6,4.4) (table I).

The socio-demographic characteristics associated with severe functioning difficulties and disability included a greater proportion of homes with a female head of household (29.1%, 95%CI 24.9,33.7 vs. 21.5%, 19.5,23.7) and heads of household with only a primary school education (38.7%, 95%CI 34.0,43.5 vs. 30.3%, 95%CI 27.8,32.9) (table II).

Table II

More children and adolescents with severe functioning difficulties and disability attended special education (19.0%, 95%CI 15.3,23.4) than those without this condition (11.1%, 95%CI 9.2,13.3) (table III). Fewer children and adolescents with severe functioning difficulties and disability had attended school in the previous school year (9.4% did not vs. 5.9% among children without a severe functioning difficulties and disability), fewer attended school in the current school year (9.8 vs. 6.4%) and more had an educational lag (8.0 vs. 4.9%).

Child labor among children and adolescents with severe functioning difficulties and disability

Of Mexican children and adolescents 5 to 17 years old in general (i.e., with or without severe functioning difficulties and disability), 13.4% do child labor, principally dangerous work (8.5%) and economic activities outside the home above the threshold specified or their age (7.5%), with only 0.6% doing housework above the specified thresholds (table IV).

Table IV

Children and adolescents with severe functioning difficulties and disability have a 70% greater likelihood of doing child labor (OR=1.7, 95%CI: 1.2,2.4) as compared to those without these difficulties (table V). Boys and male adolescents have an 80% greater likelihood of doing child labor as compared to girls and female adolescents (OR=1.8, 95%CI: 1.5,2.3). Older adolescents (those 15-19 years old) had twice the likelihood of doing child labor than those who were younger (OR=2.0, 95%CI: 1.4,2.7). Having an educational lag increased the likelihood of doing child labor; children with an educational lag had twice the likelihood of doing child labor than those without (OR=2.2,95%CI: 1.5,3.3). Living in urban areas reduced the likelihood that children and adolescents do child labor by 60% as compared with their rural peers (OR=0.4, 95%CI: 0.3,0.5).

Discussion

This study shows that 11.2% of Mexican children and adolescents 5 to 17 years old have severe functioning difficulties or disability in at least one of the measured domains and that the prevalence is higher in boys than girls. Comparison of these results with other studies is difficult given that there are few population-based surveys on this topic, the age groups studied are often quite different and above all because the way functioning difficulties and disability are measured by different instruments varies a great deal. In spite of this, in other studies a higher prevalence of functioning difficulties and disability has also been found in boys and young men as compared to girls.2121.

https://doi.org/10.1542/peds.2010-2989...
Keeping the differences in surveys in mind, a comparison shows that the survey reported on here found a higher prevalence of functioning difficulties and disability in children and adolescents living in homes with female heads of household as well as homes where the head of the household has only a primary school education.

The domains of severe functioning difficulty and disability with the highest prevalence among Mexican children 5 to 17 years old were experiencing daily anxiety and having difficulty controlling behavior, as well as a somewhat lower prevalence of daily depression. Anxiety disorders have been found to be associated with leaving school earlier.2323. Van Ameringen M, Mancini C, Farvolden P. The impact of anxiety disorders on educational achievement. J Anxiety Disord 2003;17(5):561-571. https://doi.org/10.1016/S0887-6185(02)00228-1
https://doi.org/10.1016/S0887-6185(02)00...
Also, childhood-onset of mental disorders (including anxiety disorders, disorders relating to controlling behavior and depression) has been found to be associated with not completing high school (with the same tendency for not completing primary school, but without statistical significance).2424. Breslau J, Lane M, Sampson N, Kessler RC. Mental disorders and subsequent educational attainment in a US national sample. J Psychiatr Res 2008;42(9):708-716. https://doi.org/10.1016/j.jpsychires.2008.01.016
https://doi.org/10.1016/j.jpsychires.200...
Research has yet to clarify the relationships between anxiety or depression and child labor; some authors theorize that child labor creates stress or trauma during childhood, which could lead to mental disorders at that time and later in life.2525. Edmonds EV. Child labor. IZA Discussion Papers, No. 2606. Bonn, Alemania: Forschungsinstitut zur Zukunft der Arbeit (IZA)/Institute for the Study of Labor, 2007 [accessed on May 4, 2017].

Systematic reviews show that improvements in depression and anxiety prevention programs (school-based or not)2626. Werner-Seidler A, Perry Y, Calear AL, Newby JM, Christensen H. School-based depression and anxiety prevention programs for young people: A systematic review and meta-analysis. Clin Psychol Rev 2017;51:30-47. https://doi.org/10.1016/j.cpr.2016.10.005
https://doi.org/10.1016/j.cpr.2016.10.00...
as well as cognitive behavioral therapy and interpersonal psychotherapy2727. Weersing VR, Jeffreys M, Do MT, Schwartz KT, Bolano C. Evidence Base Update of Psychosocial Treatments for Child and Adolescent Depression. J Clin Child Adolesc Psychol 2016:1-33. can be efficacious at reducing these important health problems. Either of these options (prevention programs or treatment) have the potential to reduce the possible contribution of these mental health issues on higher levels of child labor or of educational lag as well as their impact in adulthood.

This data shows important associations between educational issues and functioning difficulties and disability in Mexican children, as well as with child labor. Our data shows a to-be-expected association between functioning difficulties and disability and attending special education, since this type of school (or group within a regular school) was created specifically for children and young people with disabilities in order to promote their integral development and facilitate acquisition of skills and competencies needed to achieve their educational goals.2828. Instituto Nacional para la Evaluación de la Educación. Panorama Educativo de México 2013, Indicadores del Sistema Educativo Nacional. Educación Básica y Media Superior. Ciudad de México: INEE, 2014 School attendance and educational lag were also associated with having a functioning difficulty or disability. This reflects the issues faced by children and adolescents a functioning difficulty or disability in terms of attending school and completing age-appropriate educational levels.11. Organización Mundial de la Salud. Informe mundial sobre la discapacidad. Ginebra:OMS, 2011.,2929. Ellen-Groce N. Adolescents and youth with disability: issues and challenges. Asia Pacific Disability Rehabilitation Journal 2004;15(2):13-32. Children and adolescents with functioning difficulties or disability may have special education needs which are not being met either in special educational facilities or a group or individualized program mainstreamed into a regular school, as well as health needs, all of which can affect both school attendance and educational lag.3030. Johnson S, Hennessy E, Smith R, Trikic R, Wolke D, Marlow N. Academic attainment and special educational needs in extremely preterm children at 11 years of age: the EPICure study. Arch Dis Child Fetal Neonatal Ed 2009;94(4):F283-F289. https://doi.org/10.1136/adc.2008.152793
https://doi.org/10.1136/adc.2008.152793...

In addition, we found that children and adolescents with an educational lag are more likely to be involved in child labor. This result is consistent with previously published studies that have documented that the population that does child labor also tends to have problems with educational achievement. On average, children and adolescents who work are two years behind their standard school year and only one of every four children who work concludes their basic education.3131.

https://doi.org/10.3368/jhr.44.4.871...
This scenario is worrisome given that participation in education contributes to achieving social equity as well as constituting an opportunity for social integration and, evidently, acquiring skills and knowledge.3333.

https://doi.org/10.1080/0142569060099683...

Our study also found that Mexican children and adolescents 5-17 years of age who do child labor, do principally dangerous work (8.5%) or work outside the home, with few doing housework or chores above the level indicated for their age. This is of interest because while some child labor can benefit the child,3535. Bunch NH, Verner D. Revisiting the link between poverty and child lavor: the Ghanaian experience. Working Paper 01-03. Aarhus V, Dinamarca: Centre for Labour Market and Social Research, 2001 [accessed on May 4, 2017]. Available at: http://documents.worldbank.org/curated/en/167581468751536929/pdf/multi-page.pdf

this is not the case for dangerous work; some authors define child labor as beneficial to children only if it does not impact their educational attainment (more years of education or acquisition of specific skills such as math or reading).3636. Stabile M, Sara A. The economic cost of chilhood disability. The future of children 2012;22:65-96. https://doi.org/10.1353/foc.2012.0008

Our results show that among Mexican children and adolescents, there is an association between doing child labor and having a functional difficulty or disability; this has the potential to increase the inequalities that this group of children experiences. This is especially true given the social inequalities that families of children with functioning difficulties and disabilities experience. The evidence shows that when a household includes members with moderate or severe functioning difficulties, poor families are forced to spend a greater proportion of their income on healthcare than non-poor families. In addition, the direct and indirect costs associated with child functioning difficulties and disability are high.3636. Stabile M, Sara A. The economic cost of chilhood disability.

Our findings around these different associations between child labor and educational lag, between disability and educational issues and between child labor and disability constitute an initial exploration of a possible cycle of disadvantage through an accumulation of vulnerabilities. More research and analysis is needed to explore the directionality of these associations.

These results provide an evidence base that shows how essential it is to guarantee children’s opportunities and rights, including the most vulnerable groups. This implies developing public policy that takes into account social and economic factors and the diverse life circumstances of Mexican children and adolescents in order to promote their integral development and that each child reach his or her potential.

This survey has limitations including that measurement of functioning difficulties and disabilities is based on the mother’s or principal caretaker’s report and not a professional diagnosis. In addition, the study’s transversal design does not allow us to identify directionality in the association between child labor and functioning difficulties and disability; that is, we do not know if functioning difficulties and disability leads to higher level of child labor, or vice versa. In addition, it was not possible to analyze the relationship between child labor and specific functional difficulty and disability domains, given the sample size (number of children within each specific domain). We also do not have data about the cause of the child or adolescent’s functioning difficulty or disability, which might influence child labor or educational attainment.

In spite of these limitations, this study provides current, nationally representative data and an initial exploration of child labor and functioning difficulties and disability. These results can be the jumping off point for future, more in-depth research on the associations (and their directionality) between child labor and functioning difficulties and disability, preferably using instruments based on the International Classification of Functioning, Disability and Health (ICF) and which are internationally comparable, as was the instrument used in this study.
