GENERAL INFORMATION

10The territory of modern Guatemala once formed the core of the Maya civilization, which extended across Mesoamerica. The Spanish conquered most of the country by the 16th century. Guatemala attained independence from Spain in 1821 as part of the Federal Republic of Central America, which dissolved in 1841.

Guatemala's abundance of biologically significant and unique ecosystems includes a large number of endemic species and contributes to Mesoamerica's designation as a biodiversity hotspot. The country is also known for its rich and distinct culture, which is characterized by a fusion of Spanish and Indigenous influences.

Guatemala is a highly diverse country, populated by a variety of ethnic, cultural, racial, and linguistic groups. According to the 2010 Census conducted by the National Institute of Statistics (INE), about 41.5% of the population is Mestizo (also known as Ladino), reflecting mixed indigenous and European heritage. A similar proportion of Guatemalans (41%) are of full Amerindian ancestry, which is among one of the largest percentage in Latin America, behind only Peru and Bolivia. Most indigenous Guatemalans are of the Maya people, namely K'iche' (11.0% of the total population), Q'eqchi (8.3%), Kaqchikel (7.8%), Mam (5.2%), and "other Maya" (7.6%). Less than 1% are indigenous non-Maya.

Guatemala's sole official language is Spanish, spoken by 93 percent of the population as either the first or second language.

Twenty-one Mayan languages are spoken, especially in rural areas, as well as two non-Mayan Amerindian languages: Xinca, which is indigenous to the country, and Garifuna, an Arawakan language spoken on the Caribbean coast. According to the Language Law of 2003, these languages are unrecognized as National Languages.

In terms of religion, a 2012 survey estimated Catholics at 47.6%, Protestants at 38.2%, other religions at 2.6%, and the non-religious at 11.6%.

From 1970 to 2016, and particularly since the 1990s, Guatemala has experienced the rapid growth of  Protestantism, currently more than 38% of the population, and still growing.

Guatemala is a constitutional democratic republic whereby the President of Guatemala is both head of state and head of government, and of a multi-party system. The president exercises Executive powerLegislative power is vested in both the president and the Congress of the Republic. The judiciary is independent of the executive and the legislature.

Guatemala is the largest economy in Central America, with a GDP (PPP) per capita of US$5,200. Guatemala faces many social problems and is one of the poorest countries in Latin America. The distribution of income is highly unequal with more than half of the population below the national poverty line and just over 400,000 (3.2%) unemployed. The CIA World Fact Book considers 54.0% of the population of Guatemala to be living in poverty.

 

History of Audiology

 

Audiology services are present in Guatemala; however, there is only one university trained audiologist in the country.  Approximately 40 years ago, the first audiology shop started dispensing hearing aids; no diagnostic or repair services were available. 

Some years later, a second shop opened its doors.  This one had 4
better technology and more options for the clients.

As for pediatric services, hearing aids were being fitted without proper diagnosis; ABRs were being done by neurologists and no behavioral observation techniques were used.

Hearing aids were mainly Body aids and BTEs; very few people would try custom hearing aids, which were locally done.  Digital technology was still years away.

In 1990 a new clinic opened its doors led by a young professional with a master’s degree in Education for the Deaf from Gallaudet University. 
 This clinic offered top of the line hearing aids, which were assembled in the United States.  This seemed to be a trend for users who were looking for something new.  This clinic, Centro de Audición, CEDAF, rapidly became the leader in hearing services and was responsible for introducing new technology through the years.  Some examples are: the first completely in the canal (CIC) hearing aid line, the first digital aids, otoacoustic emissions (OAEs), Auditory Steady State Response (ASSR), cochlear implants, bone anchored and middle ear implants, vestibular diagnosis (with equipment), real-ear measurements, and behavioral observation audiometry (with all its variants).

During this time, the clinician pursued further studies and completed her Doctorate of Audiology at University of Florida.

After CEDAF, came few other clinics, most of which were opened by former employees of audiologic clinics.  They had some training, which was received during the time of their prior employment.

To date, there are approximately 10 hearing clinics throughout the country. Except for tw
o, all of them offer hearing aid fitting and pure tone audiometry.  One offers: hearing aid fitting, Auditory Brainstem Response (ABR), pure tone audiometry (PT) and recently vestibular testing.  CEDAF offers: neonatal and school hearing screening, diagnostics for all ages (PT, ABR, and ASSR), all types of implants, vestibular diagnosis and rehabilitation, and hearing, speech and language therapy.

Hearing loss incidence and prevalence

2Guatemala does not have prevalence nor incidence studies for hearing loss or any other disability; however, we have one of the highest birthrates in Latin America.  According to the National Institute of Statistics, it is 2.4%, which in 2016 meant that approximately 1000 babies were born every day.  If conservative international rates are applied, Guatemala should expect an average of 3 babies born every day with some degree of hearing loss.

INFORMATION ABOUT AUDIOLOGY

Education

No programs are available in Guatemala for audiology training.  Speech and language therapy is available as an undergraduate program in a public university.

 

Audiology Practice : Public Vs Private

Public Health System, through the S8ocial Security: offers diagnostic services through contracts with private practitioners. Hearing aids are given to children who completed their diagnostic tests before age five and whose parents are working either in private or public sector. Adults may receive hearing aids if they are prescribed before retirement and is not congenital type of loss. Hearing aids are very basic, for both children and adults. All these services are free of charge. Cochlear implants are not available through the public health services.

• Private Sector: As mentioned before, through the private clinics most all-audiological services are available. There are differences in prices and quality among clinics.

• Non-profit organizations:
Sonrisas que Escuchan / Smiles that Listen Foundation, which started in 2009. To date, it offers all services listed in the table below, except for cochlear implants.

Benemérito Comité Pro Ciegos y Sordos: is a non-profit that serves people who are blind and/or deaf. They offer educational, medical, and rehabilitation services. Within the medical services they offer the following audiological services: ABR, pure tone audiometry, tympanometry and hearing aid fitting (very basic technology).

Another program that does not offer services but instead collects money to support cochlear implantation is Ayúdame a Escuchar. It started in 2014; however, a drawback is that they do not have audiology professionals locally, so they bring an Ear, Nose, and Throat (ENT) surgeon for each surgery and an audiologist comes twice a year to MAP the implants. There are no spare parts or distributor of the brand in Guatemala.

    • Few trained people in the field of audiology
    • No Audiology preparation programs available
    • Lack of sufficient trained professionals, opens space to unethical “humanitarian missions”
