Evaluating awareness of health risks and self-reported symptoms among nail technicians in Johannesburg, South Africa ­ a pilot study

ABSTRACT

Background: The professional nailcare industry is expanding rapidly in South Africa. Nail treatment involves the use of solvents and acrylates. Exposure to these chemicals is associated with skin, eye, and respiratory tract irritation, and neurological and reproductive health effects. Objective: To test the feasibility of conducting a study on formal and informal nail technicians, which included testing a self-developed questionnaire, and to collect preliminary data about their knowledge and awareness of health risks associated with exposure to chemicals in nail products, and associated symptoms. Methods: A self-developed questionnaire was administered to 10 formal and 10 informal nail technicians working in conveniently selected nail salons in Johannesburg. Work practices and exposure control measures were observed. Demographic characteristics, working conditions, awareness of health risks, and self-reported symptoms in the two groups are presented as frequency distributions. Results: Poor phrasing was identified in some of the questions. Participants provided the correct terminology to describe nail services. The revised questionnaire comprised 39 questions. Seven of the informal nail technicians were male while all the formal nail technicians were female. Informal nail technicians worked longer hours per week than formal nail technicians (median of 61.5 and 46.5 hours, respectively) and reported more symptoms. Informal nail technicians used a wider range of nail products than formal nail technicians and used some unknown brands. Although all participants indicated that they were aware of health risks associated with nail products, only four of the formal nail technicians and one informal nail technician reported receiving training (although not specific to health and safety). Informal nail technicians reported using personal protective equipment (PPE); however, this practice was inconsistent, and they used the incorrect PPE. Conclusions: We showed that conducting a larger study in nail technicians is feasible. The questionnaire was revised to include more information about the chemical content of nail products, a wider range of symptoms, the frequency of their occurrence, and the work-relatedness nature of the self-reported symptoms. A knowledge gap was identified among nail technicians relating to risks associated with exposure to chemicals in nail products. The questionnaire was refined to assess more accurately nail technicians' understanding of exposure and awareness of health risks associated with chemicals in nail products.
