RESUMO:

 

Background: Approximately 5% of the occupied population in Brazil works in their
own households. However, little is known about they work conditions, especially
occupational-related exposures that can potentially affect their health. Objectives:
This study describes the occupational characteristics, and occupational exposures,
potential risk factors for health, among home-based informal workers (HBW).
Materials and methods: This study is part of National Health System (SUS)
Integration Project, of teaching-research-cooperation, an initiative of the Institute of
Collective Health, Federal University of Bahia (ISC-UFBA), carried out in the Health
District of Freedom, Salvador, the state of Bahia, Brazil. One of its subprojects, the
Occupational Health Integration in Primary Health Care, trained community health
agents (CHA) to participate in the workers‘ health care and surveillance. As part of
the diagnosis and training, this cross-sectional survey was carried out with workers
living in areas covered by the Family Health Strategy and Community Health Agents
Program (Primary Health Care). Data from the Primary Health Care Information
System (SIAB) was used to identify HBW in the catchment area. Later, trained
interviewers joined CHA household visits to collect detailed occupational data.
Electronic questionnaires on tablets were used, together with quantitative
measurements of formaldehyde (ppm) and noise (dB(A)) assessed by dosimeters.
Results: In the areas covered by Primary Health Care in the Health District, 468
HBW were identified, mostly from retail (35.3%), production and sale of food (25.8%),
personal services/beauty (17.1%), clothing manufacturing (9.4%), and others
(12.4%). The majority of workers was female (77.1%), from 40 years of age or older
(67.3%) and own-account (92.5%), with over 44 hours of work time per week
(62.5%), with no vacations (63.0%). Most reported working every day (45.0%). The
prevalence of perceived noise-related occupational exposure (P-NE), i.e. when one
needs to raise the voice to be understood, was 16.4%. It was higher in the group of
more than 44 hours per week (20.1%), with higher income (19.1%) and among those
of 18 to 39 years of age (18.9%). Among 18 samples from 10 beauty salons, the
level of formaldehyde in the air was above the limit of 0.3 ppm (American Conference
of Governmental Industrial Hygienists, ACGIH) in 9 (50.0%) measurements. Among
female beauty service workers, hairdressers had a mean noise exposure of 75.1 dB
(A), less than the maximum LAEq, 8 h = 85 dB (A) as defined by the National Institute
for Occupational Safety and Health), higher, however, than the levels for the home
environment (Brazilian Association of Technical Standards, ABNT) of LAeq = 40 dB for
living room and LAeq = 30 dB in bedrooms. Conclusions: Informal workers in HBW
are commonly poor, have long working hours, with almost no resting time. They are
mostly women, from services and trading and do not contribute to social insurance.
They are commonly exposed to occupational noise, notably from external sources,
and to chemical agents, specifically formaldehyde, known carcinogenic. These
findings support the participation of Primary Health Care teams in the informal work
environment surveillance, and their strategic role in prevention of occupational health
hazards and their health effects in workers and families.
