“…This study primarily aimed to establish the prevalence of respiratory symptoms and the associated risk factors among street food vendors in Klang Valley, Malaysia. Various previous studies explored the respiratory health of roadside hawkers in countries such as Nigeria (Nwankwo et al 2018), Ghana (Amegah et al 2021), Thailand (Kongtip et al 2008), India (De et al 2019;Prabhu et al 2019), Brunei Darussalam (Wahid et al 2014) Egypt (Serya et al 2019) and South Africa (Sepadi and Nkosi 2022). However, there are only limited number of studies undertaken in Malaysia to understand the prevalence and risk factors of respiratory symptoms among the high-risk population of street food vendors.…”

The street vendors in Malaysia are at an increased risk of developing respiratory symptoms owing to the continuous exposure to road dust, vehicle emissions, extreme weather conditions, and air pollutants from industrial sites. Hence, the current study aimed to establish the prevalence of respiratory symptoms and the risk factors associated with it among street food vendors in Klang Valley, Malaysia through a cross-sectional study among 237 street food vendors. The socio-demographic data, work characteristics, and information on respiratory symptoms were collected using a self-administered questionnaire. The data analysis was done by using the Chi-square test of association and frequency distribution. The study results revealed that the most frequently reported respiratory symptoms among the street food vendors were sore throat (30.8%), followed by cough (29.1%). No significant association was found between age, gender, duration of job and cough, sputum production, breathing difficulty, chest pain, irritated nose, and sore throat. A statistically significant association was found between working hours and sputum production (p=0.014). Further, the working hours were significantly associated with breathing difficulty (p=0.011). A significant association was also found between the type of cooking fuel used and the presence of cough (p=0.001). Results of this study demonstrated a positive association between work-related risk factors such as working hours with breathlessness and sputum production, and also between cough and the type of cooking fuel used. Based on the aforementioned findings, various control measures such as regular monitoring of lung functions and health education programs can be undertaken. Moreover, vendors need to consider using clean fuels instead of charcoal.

Introduction: Informal street vending is a form of informal employment, and occupational conditions for people within this group have been proven to be detrimental to their health. Two independent reviewers carried out a systematic evaluation of the existing literature in South Africa on environmental and occupational exposures, as well as the health effects faced by informal street food vendors. Methods: 354 published publications were reviewed and 9 were included, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: The evidence showed that informal street vendors are exposed to workplace risks that affect their health and wellbeing. Non-enclosed vendor stalls and frequent use of open fires were among the risk concerns. Vendors are vulnerable to gastrointestinal diseases such as salmonellosis and respiratory infections such as influenza and COVID-19 due to inadequate access to water, waste disposal facilities, and basic hygiene awareness and practices. Exposure to air pollutants increased the risk of respiratory and urinary illnesses and an impact on the reproductive health of female street vendors. Conclusions: This investigation demonstrated the difficulties in complying with the requirements of the Regulations Governing General Hygiene Requirements for Food Premises, the Transport of Food, and Related Matters (no. R638 of 22 June 2018) and the Occupational Health and Safety (OHS) Act (no. 85 of 1993). Within South African borders, there is a scarcity of research on occupational exposures and health effects in this occupation. As a result, eliminating or preventing these occupational exposures should be at the top of government and stakeholder agendas. The majority of the research was carried out in KwaZulu Natal and used a quantitative, cross-sectional technique. Other designs, including cohorts, time series, and randomized intervention trials, were underutilized.
