Background:

Overweight and obesity are escalating public health challenges in South Africa. Healthcare workers (HCWs), expected to model healthy behaviours, are increasingly exposed to obesogenic environments, placing them at higher risk for poor dietary habits and obesity. This study investigated the prevalence of obesity and assessed dietary behaviours and workplace environmental influences among primary healthcare workers in Limpopo Province.

Methods:

A quantitative cross-sectional design was used. A total of 174 healthcare workers from clinics in Lepelle-Nkumpi Municipality participated. Stratified random sampling ensured representation across nursing, allied health, and support staff. Data were collected using a validated, self-administered questionnaire and Food Frequency Questionnaire. Anthropometric measurements were taken to calculate Body Mass Index (BMI). Data were analysed using SPSS version 28, with descriptive statistics and chi-square tests ( p  < 0.05) employed to explore associations.

Results:

Among participants, 76% were overweight (28%) or obese (48%), with significantly higher obesity prevalence among females ( p  = 0.001). A substantial proportion reported weekly fast-food consumption (50%), access to fast-food vendors near clinics (39.1%), and regular exposure to food advertisements (40.8%). Diets were characterized by frequent intake of full cream milk (64.9%), chicken with skin (53.4%), fried foods (47.7%), and low consumption of fruits and vegetables. Only 21.8% consumed traditional vegetables like spinach/morogo daily.

Conclusion:

This study reveals a high prevalence of overweight and obesity among healthcare workers, linked to unhealthy dietary patterns shaped by workplace food environments, fast-food access, and time constraints. Findings highlight the need for multi-level, culturally sensitive interventions and further exploration of home-based dietary influences.
